An intelligent switch

Abstract

This application provides a wall-mounted smart switch, a wireless smart switch, and a switch mounting bracket. The wall-mounted smart switch includes a housing, a detection element, a wireless communication module, a reset unit, and at least one button. The button is disposed in the housing, and at least a portion of the button can respond to a control force to undergo a pressing movement, thereby generating displacement and a reaction force, such that the button passes through at least a first pressing position and a second pressing position in sequence. The reset unit responds to the displacement to generate a reset force, which cooperates with the first rebound force of the detection element, such that when the button is in the first pressing position, the reaction force is F1, and when the button is pressed from the first pressing position to the second pressing position, the reaction force of the button jumps from F1 to F2; wherein, F2 < F1 < 400g; the difference between the displacement of the button in the first pressing position and the displacement in the second pressing position is ≤2mm. This improves the smoothness of button pressing while also providing clear feedback to the user.

Description

[0001] This application is a divisional application. The original application's application number is 202280002415.5, the invention title of the original application is "A smart wall switch, a wireless smart switch and a switch mounting bracket", and the application date of the original application is November 25, 2022. Technical Field

[0002] This application relates to the field of switches, and more particularly to a smart switch. Background Technology

[0003] Smart switches typically consist of a button, a sensor, and a wireless communication module. The user applies force to the button, causing it to move. This movement triggers the sensor, which in turn controls the switch's on / off state. The wireless communication module receives and transmits wireless signals, allowing the switch to operate based on these signals. However, existing smart switches exhibit noticeable rebound force jumps during button presses, with significant displacement, resulting in a strong tactile feedback when pressing the button. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a wall-mounted smart switch, a wireless smart switch, and a switch mounting bracket.

[0005] According to a first aspect of the present invention, a smart wall switch is provided, comprising a housing, at least one button, a detection element, a reset part, and a wireless communication module. The button is disposed in the housing, and at least a portion of the button is capable of being pressed in response to a control force, thereby generating displacement, such that the button passes through at least a first pressing position and a second pressing position in sequence, and generates a reaction force. The detection element can be triggered based on the displacement and generates a first rebound force resisting the displacement. The reset part is configured to support the button to deform directly or indirectly in response to the pressing movement and generate a reset force to overcome the deformation. The wireless communication module is electrically connected to the detection element to receive a trigger signal from the detection element and controls the on / off state of the smart wall switch based on the trigger signal.

[0006] The detection element and the reset part cooperate to ensure that: when the button moves to the first pressing position, the reaction force is F1, and when the button moves from the first pressing position to the second pressing position, the reaction force changes from F1 to F2; wherein, F2 < F1 < 400g; the displacement S1 of the button at the first pressing position and the displacement S2 of the button at the second pressing position satisfy the relationship: S2 - S1 ≤ 2mm.

[0007] According to a second aspect of the present invention, a wireless smart switch is also provided, comprising a housing, at least one button, a detection element, a reset part, and a wireless communication module. The button is disposed in the housing, and at least a portion of the button is capable of being pressed in response to a control force, thereby generating displacement, such that the button passes through at least a first pressing position and a second pressing position in sequence, and generates a reaction force. The detection element can be triggered based on the displacement and generates a first rebound force resisting the displacement. The reset part is configured to support the button to deform directly or indirectly in response to the pressing movement and generate a reset force to overcome the deformation. The wireless communication module is communicatively connected to the detection element to receive a corresponding trigger signal and to send wireless messages externally based on the trigger signal.

[0008] The detection element and the reset part cooperate to ensure that: when the button moves to the first pressing position, the reaction force is F1, and when the button moves from the first pressing position to the second pressing position, the reaction force changes from F1 to F2; wherein, F2 < F1 < 400g; the displacement S1 of the button at the first pressing position and the displacement S2 of the button at the second pressing position satisfy the relationship: S2 - S1 ≤ 2mm.

[0009] According to a third aspect of the present invention, a switch mounting bracket is also provided, including an integral frame configured to mount the aforementioned wall smart switch and / or the aforementioned wireless smart switch; the integral frame is provided with at least one switch mounting position, and the wall smart switch or the wireless smart switch is detachably connected to the switch mounting position.

[0010] The beneficial effects of this invention are as follows:

[0011] The wall-mounted smart switch and wireless smart switch provided by this invention, by setting a reset part and a detection element that cooperate with the button, link the reaction force generated by the button during pressing to the reset force provided by the reset part and the first rebound force provided by the detection element. The reset force and the first rebound force are configured such that the reaction force when the button is pressed from the first pressing position to the second pressing position is less than or equal to 400g. Therefore, the pressing force required for the button's triggering process can be controlled within 400g, making it easier for the user to press the button and optimizing the user experience. Furthermore, by setting the displacement difference between the first and second pressing positions of the button to less than or equal to 2mm, the amount of displacement that jumps during the button's pressing process is reduced to within 2mm, reducing the stickiness when the user presses the button and improving the smoothness of the button's pressing. Simultaneously, because the amount of displacement that jumps during the button's pressing process is reduced, the feedback from the button trigger detection element is more crisp, reducing the stickiness of the button's pressing. This allows the button to provide clear feedback to the user while improving the smoothness of the pressing process. Attached Figure Description

[0124] In the description of this invention, the terms "inner", "outer", "longitudinal", "lateral", "upper", "lower", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and do not require that this invention must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0125] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0126] In the description of this invention, unless otherwise explicitly specified and limited, the term "connection" and other such terms should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0127] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0128] Please see Figures 1-56 ,based on Figures 1-56The present invention provides a specific description of a wall-mounted smart switch 101. When in use, the wall-mounted smart switch 101 is fixedly installed on a wall, floor, or other fixed mounting surface and connected to the household electrical circuit. It is electrically connected to the controlled device and can control the power supply of the controlled device. It also has wireless communication capabilities, can receive wireless messages, and execute corresponding control commands according to the content of the wireless messages, thereby controlling the power supply of the corresponding controlled device.

[0129] Specifically, such as Figure 1 and Figure 2 As shown, the wall smart switch 101 includes at least: a housing 14, at least one button 11, a detection element 12, and a wireless communication module 13; wherein:

[0130] The button 11 is disposed on the housing 14. At least a portion of the button 11 can be pressed in response to a control force, thereby generating displacement, such that the button 11 passes through at least a first pressing position and a second pressing position in sequence, and generates a reaction force. The detection element 12 can be triggered based on the displacement and generates a first rebound force to resist the displacement. The reset part 15 is configured to support the button 11 to deform directly or indirectly in response to the pressing movement and generate a reset force to overcome the deformation. The wireless communication module 13 is electrically connected to the detection element 12 to receive the trigger signal of the detection element 12 and control the on / off state of the wall smart switch 101 based on the trigger signal.

[0131] The statement that at least a portion of the button 11 can respond to a control force to undergo a pressing motion should be understood as meaning that a local portion of the button 11 can respond to the control force to undergo a pressing motion, or that the entire button 11 can respond to the control force to undergo a pressing motion. The pressing motion can be, for example, a pivoting motion, a linear motion, or a composite motion of displacement and rotation. The reaction force should be understood as the reaction force generated by the part of the button 11 that has been pressed and displaced relative to the control force, in the opposite direction to the displacement. The detection element 12 can be a push-button switch with a self-resetting function, thus generating the first rebound force resisting the pressing of the button 11 when triggered. The statement that the wireless communication module 13 controls the on / off state of the wall smart switch 101 based on the trigger signal can be understood as meaning that the wireless communication module 13 can trigger a switch on / off command, thereby controlling the power supply and de-energization of the controlled device. The user can operate the button 11 to trigger the detection element 12, and the wireless communication module 13 controls the switch on / off state according to the triggering of the detection element 12. Furthermore, the user can also send wireless messages to the switch, and the wireless communication module 13 controls the switch to be turned on or off according to the instructions in the wireless messages.

[0132] Among them, such as Figure 5As shown, the detection element 12 and the reset part 15 cooperate to ensure that: when the button 11 moves to the first pressing position, the reaction force is F1, and when the button 11 moves from the first pressing position to the second pressing position, the reaction force changes from F1 to F2; wherein, F2 < F1 < 400g; the displacement S1 of the button 11 at the first pressing position and the displacement S2 at the second pressing position satisfy the relationship: S2 - S1 ≤ 2mm.

[0133] As can be seen, the above solution, by setting a reset part 15 and a detection element 12 that cooperate with the button 11, makes the reaction force generated by the button 11 during the pressing process related to the reset force provided by the reset part 15 and the first rebound force provided by the detection element 12. Furthermore, the reset force and the first rebound force are configured such that the reaction force of the button 11 when it is pressed from the first pressing position to the second pressing position is less than or equal to 400g. Therefore, the pressing force required for the button 11 to be triggered can be controlled within 400g, making it easier for the user to press the button 11 and thus optimizing the user experience. It should be noted that 400g here represents the weight of a 400-gram object. Furthermore, the above solution also reduces the amount of displacement of button 11 during the pressing process by setting the displacement difference between the first pressing position and the second pressing position to less than or equal to 2mm. This reduces the stickiness when the user presses button 11, improving the smoothness of pressing button 11. At the same time, because the amount of displacement during the pressing process of button 11 is reduced, the feedback of button 11 triggering the detection element 12 is more crisp, reducing the stickiness of pressing button 11. This allows button 11 to provide clear feedback to the user while improving the smoothness of pressing.

[0134] like Figure 5 and Figures 69-76 The figure shows the force-displacement curves of multiple switch presses. The applicant designed various switch structures, configured different types of detection elements 12, and conducted pressure tests using a press machine. The press machine's contacts press against the button 11, causing the button 11 to generate displacement and reaction force during the pressing process. Force and displacement sensors are installed on the press machine's contacts. The press machine records the force-displacement curves during the pressing and rebound processes of the button 11. The vertical axis in the figure represents the pressing force, and the horizontal axis represents the displacement of the button 11. The left side shows the curve when pressing the main pressing area of ​​the button 11 (the middle position of the button 11), and the right side shows the curve when pressing the corner position of the button 11. Each side has two curves: the upper one is the curve during pressing, and the lower one is the curve during rebound. For details, see [link to details]. Figure 5 and Figures 69-76 The curve on the left side of the middle, Figure 5In the given condition, F1 = 252.62 g, and S2 - S1 < 0.2 mm; Figure 69 In the given condition, F1 = 50.25g, and S2 - S1 < 0.3mm; Figure 70 In the given condition, F1 = 50.25g, and S2 - S1 < 0.3mm; Figure 70 In the given condition, F1 = 102.27 g, and S2 - S1 < 0.3 mm; Figure 71 In the given condition, F1 = 130.95g, and S2 - S1 < 0.6mm; Figure 72 In the middle, F1 = 95.49g, S2 - S1 < 1mm; Figure 73 In the given condition, F1 = 237.99 g, and S2 - S1 < 0.2 mm; Figure 74 In the given condition, F1 = 199.55g, and S2 - S1 < 0.3mm; Figure 75 In the given condition, F1 = 341.97g, and S2 - S1 < 0.2mm; Figure 76 In the diagram, F1 = 264.94g, and S2 - S1 < 0.3mm. Therefore, the reaction force of the switch structure button 11 designed by the applicant is less than or equal to 400g, and the displacement difference between the first and second pressing positions of button 11 is less than or equal to 2mm. This makes pressing button 11 less strenuous for the user and improves the smoothness of button 11 pressing.

[0135] Furthermore, such as Figure 5As shown, the reset part 15 is also configured to use the reset force to drive the button 11 to perform a reset movement, so that the button 11 passes through at least the first rebound position, the second rebound position and the third rebound position in sequence; the reset force of the reset member cooperates with the first rebound force of the detection member 12, so that when the button 11 is in the first rebound position, the reaction force is F3, and when the button 11 rebounds from the first rebound position to the second rebound position, the reaction force jumps from F3 to F4, and the reaction force at the third rebound position is 0; wherein, F4 > F3 ≥ 22g, F2 < F1, and F3 / F1 > 0.3. When button 11 triggers the detection element 12, the user withdraws the operating force, and button 11 rebounds. During the rebound, button 11 is subjected to the reset force of the reset part 15, the first rebound force of the detection element 12, and the elastic force generated by the deformation of button 11 itself. Simultaneously, during the rebound, the user's finger does not leave the surface of button 11, and button 11 is still subjected to the user's operating force and the supporting force of the housing 14. Under the combined action of these forces, button 11 rebounds. This rebound motion, influenced by the interaction between the forces, can be uniform motion, accelerated motion, decelerated motion, or a combination of these. The reaction force of button 11 mainly consists of the reset force and the first rebound force. By controlling the reset force and the first rebound force and performing structural design (see the specific button structure embodiment below), and after multiple pressing tests, the applicant ensures that when button 11 rebounds from the first rebound position to the second rebound position, the reaction force of button 11 is greater than or equal to 22g, guaranteeing sufficient rebound force. See also... Figure 5 and Figures 69-76 The curve on the left side shows that F1 represents the reaction force of button 11 when the detection element 12 changes from a non-triggered state to a triggered state, and F3 represents the reaction force of button 11 when the detection element 12 changes from a triggered state to a non-triggered state. Figure 5 Medium, F4>F3=180.35g, F3 / F1=0.71; Figure 69 Medium, F4>F3=33.53g, F3 / F1=0.67; Figure 70 Medium, F4>F3=34.95g, F3 / F1=0.34; Figure 71 Medium, F4>F3=23.77g, F3 / F1=0.18; Figure 72 Medium, F4>F3=35.15g, F3 / F1=0.37; Figure 73 Medium, F4>F3=161.51g, F3 / F1=0.68; Figure 74 Medium, F4>F3=72.39g, F3 / F1=0.36; Figure 75 Medium, F4>F3=199.82g, F3 / F1=0.58; Figure 76 In the figure above, F4 > F3 = 119.21g, F3 / F1 = 0.45. As can be seen from the figure above, the applicant optimized the relationship between the reset force and the first rebound force, and controlled F3 / F1 > 0.3, so that the force of the button 11 pressing and the trigger detection element 12 during the rebound process would not differ too much, thereby reducing the stickiness of the button 11 trigger detection element 12.

[0136] Furthermore, the difference between F1 and F3 is less than or equal to 70g. This ensures that the force applied to the trigger detection element 12 during the pressing and rebound of button 11 is not significantly different, reducing the stickiness of the trigger detection element 12 and improving the smoothness of button 11 pressing and rebounding. Further, in a preferred embodiment, the difference between F1 and F3 is less than or equal to 20g. See details below. Figure 69 , Figure 70 and Figure 72 The curve on the left side of the middle, Figure 69 In the middle, F1-F3 = 16.72g; Figure 70 In the middle, F1-F3 = 67.32g; Figure 72 In the middle, F1-F3 = 60.34g;

[0137] Furthermore, such as Figure 6 and Figure 18As shown, the button 11 is movably connected to the housing 14; the button 11 is provided with an abutment portion 113 facing the detection element 12, which is used to press and trigger the detection element 12. The detection element 12 is provided with a force guide 121 at a corresponding position of the abutment portion 113. The force guide 121 moves in response to the pressure of the abutment portion 113. When the force guide 121 moves to a preset position, the contact force between it and the abutment portion 113 changes abruptly. The connection method between the button 11 and the housing 14 and the positional relationship of the abutment portion 113 relative to the button 11 are adapted to the force guide 121 so that when the button 11 is pressed, the reaction force changes from F1 to F2, and when the button 11 rebounds, the reaction force changes from F3 to F4. The movable connection includes a pivot connection, a slide rail connection, a movable snap-fit ​​connection, an elastic arm connection, or other connection methods that can be implemented by those skilled in the art. The button 11 can be pressed to move, including pivoting motion, linear motion, or a combination of displacement and rotation. The connection method between the button 11 and the housing 14, and the positional relationship of the contact part 113 relative to the button 11, adapted to the force guide 121, can be understood as follows: the applicant designs various connection structures between the button 11 and the housing 14 to obtain various relative motion modes between the button 11 and the housing 14, and selects a suitable connection structure through force analysis and optimizes the structure to obtain a structure that conforms to the pressing and rebound characteristics of the present invention. The position of the contact part 113 on the button 11 has a direct impact on the pressing and rebound force and displacement of the button 11. The applicant changes the position of the contact part 113 relative to the button 11 and performs force analysis to obtain a position that conforms to the pressing and rebound characteristics of the present invention, so that when the button 11 is pressed, the reaction force jumps from F1 to F2, and when the button 11 rebounds, the reaction force jumps from F3 to F4.

[0138] Furthermore, such as Figure 18As shown, the detection element 12 further includes an elastic force converter 122. The force guide 121 abuts against the elastic force converter 122 and is movable relative to the detection element 12. The elastic force converter 122 is configured to receive a pressure and undergo elastic deformation, generating elastic force. When the pressure reaches a preset value, the elastic force changes. When the button 11 responds to the operating force and undergoes displacement, the force guide 121 responds to the displacement of the button 11 by pressing against the elastic force converter 122 and undergoing elastic deformation. When the control force increases to F1, the force guide 121 acts on the elastic force converter 122 to reach the preset value, and the elastic force of the elastic force converter 122 changes, so that the reaction force of the button 11 changes from F1 to F2. When the button 11 rebounds, the control force gradually decreases to F3, and the force guide 121 acts on the elastic force converter 122 to reach another preset value, and the elastic force of the elastic force converter 122 changes, so that the reaction force of the button 11 changes from F3 to F4. The elastic force converter 122 can be a spring or a sheet spring. The force guide 121 abuts against the elastic force converter 122 and can move relative to the detection element 12. The elastic force converter 122 can receive a pressure and undergo elastic deformation to generate elastic force. When the pressure reaches a critical pressure, the elastic force jumps, and the metal contact at the right end of the sheet spring moves quickly from the upper limit position to the lower limit position, thereby switching the on / off state of the detection element 12 (i.e., being triggered). When the button 11 is displaced in response to the operating force, the button 11 directly or indirectly presses against the guide member 121. The guide member 121 moves and presses against the elastic spring inverter 122, causing elastic deformation. When the operating force increases to F1, the pressure exerted by the guide member 121 on the elastic spring inverter 122 reaches the critical pressure, and the elastic force of the elastic spring inverter 122 changes abruptly. Combined with the reset force of the reset part 15, the reaction force of the button 11 changes from F1 to F2. When the button 11 rebounds, the operating force gradually decreases. When the operating force decreases to F3, the pressure exerted by the guide member 121 on the elastic spring inverter 122 reaches another critical pressure, and the elastic force of the elastic spring inverter 122 changes abruptly. Combined with the reset force of the reset part 15, the reaction force of the button 11 changes abruptly from F3 to F4. The detection element 12 can be a micro switch, tactile switch, membrane switch, piezoelectric switch, or other switches that can be implemented by those skilled in the art. The applicant selects the detection element 12 and applies its triggering force and triggering displacement parameters to the structure of the button 11 for force analysis, thereby obtaining a detection element 12 model that conforms to the structure of the button 11, so that the pressing and rebound characteristics of the button 11 achieve the expected results of this invention.

[0139] Furthermore, such as Figure 5 and Figures 69-76 As shown, the difference between the reaction force F1 of the button 11 in the first pressed position and the reaction force F2 of the button 11 in the second pressed position is set as F3, and F3 < 0.5F1. The reset part 15, in conjunction with the detection element 12, optimizes the ratio of the reset force and the first rebound force, and improves the design of the button 11 structure and the selection of the detection element 12. This reduces the jump in the elastic force when the button 11 triggers the detection element 12, thus buffering the impact of the button 11 on the user's finger and improving the smoothness of pressing.

[0140] Furthermore, such as Figure 5 and Figures 69-76 As shown, the maximum displacement of button 11 in response to the operating force is set as S4. When button 11 is in the first pressed position, the displacement of button 11 is set as S3, wherein the operating displacement margin ratio (S4-S3) / S4≥0.2. Specifically, in designing the button 11 structure, button 11 is designed with a maximum pressing amount, i.e., the maximum displacement. When button 11 reaches the maximum pressing amount, button 11 abuts against housing 14, and button 11 is difficult to press further. The operating displacement margin ratio reflects the amount of pressure button 11 can continue to apply after triggering detection element 12. In the design of button 11 structure, the dimensional fit between button 11 and housing 14 is controlled so that the operating displacement margin ratio is greater than or equal to 0.2, ensuring that button 11 still has pressing margin after triggering detection element 12, guaranteeing successful triggering of detection element 12.

[0141] Furthermore, the control displacement margin at the corner of the button 11 is 0.5 times greater than the control displacement margin at the center of the button 11. By increasing the rigidity of the button 11 and reducing its deformation, the control displacement margin at the corner of the button 11 is kept relatively close to that at the center, thereby improving the tactile feel of pressing the button at its corner.

[0142] Furthermore, such as Figure 2As shown, the button 11 is movably connected to the housing 14. The housing 14 can restrict the button 11 to at least two displacement degrees of freedom and at least one rotational degree of freedom, enabling the button 11 to undergo displacement and / or rotational movements, and triggering the detection element 12 during the movement. The movable connection includes a pivot connection, a slide rail connection, a movable snap-fit ​​connection, an elastic arm connection, or other connection methods that can be implemented by those skilled in the art. The housing 14's ability to restrict the button 11 to at least two displacement degrees of freedom and at least one rotational degree of freedom can be understood as follows: the button 11 has three displacement degrees of freedom and three rotational degrees of freedom. The housing 14 restricts the button 11 to at least two displacement degrees of freedom and at least one rotational degree of freedom, meaning that the button 11 can move with a maximum of one displacement degree of freedom and two rotational degrees of freedom. The button 11 generates movement under the constraint of the housing 14, including pivotal movement, linear movement, or a combination of displacement and rotation. The specific movement mode is determined by the connection structure between the button 11 and the housing 14.

[0143] Furthermore, in this embodiment, as Figure 3 and Figure 4As shown, the reset part 15 is configured with at least one elastic limiting member 151, and the housing 14 is provided with the elastic limiting member 151 at the corresponding position of the button 11. The elastic limiting member 151 is a cantilever beam structure, including a fixed end 1511 and a free end 1512 away from the fixed end 1511. The fixed end 1511 is fixedly connected to or integrally formed with the housing 14, and the free end 1512 abuts against the button 11 to provide a reset force for the button 11. At the same time, the free end 1512 of the elastic limiting member 151 is positioned and connected to the button 11 to restrict the two displacement degrees of freedom and one rotational degree of freedom of the button 11 in the horizontal direction, so that the button 11 can undergo a superimposed displacement and rotational movement in the vertical direction. The provision of the elastic limiting member 151 at the corresponding position of the button 11 in the housing 14 can be understood as the elastic limiting member 151 provided in the housing 14 being able to abut against the bottom or side of the button 11 to provide a reset force for the button 11. The positioning connection can be understood as a connection method with positioning function, including setting a positioning pin and a positioning post on the button 11 and the free end 1512 respectively, with the positioning pin and positioning post cooperating to position the free end 1512 and the button 11; or opening a positioning groove on the button 11, the shape of which is adapted to the free end 1512, so that the free end 1512 is positioned by the positioning groove; or other connection methods with positioning function that can be implemented by those skilled in the art. The button 11 being able to undergo a superimposed motion of displacement and rotation in the vertical direction can be understood as the button 11 having 3 displacement degrees of freedom and 3 rotation degrees of freedom. The housing 14 restricts two displacement degrees of freedom and one rotational degree of freedom in the horizontal direction of the button 11, and releases one displacement degree of freedom and two rotational degrees of freedom in the vertical direction of the button 11, so that the button 11 can tilt and move downward in response to the operating force, thereby pressing and triggering the detection element 12.

[0144] The intelligent switch provided by this invention features a button 11 supported and positioned by an elastic limiting member 151. The button 11 has a high degree of freedom; when pressed, it undergoes a combined displacement and rotational motion, allowing it to tilt in multiple directions. This makes the button 11 surface more ergonomically designed to fit the user's finger, and minimizes the difference in pressing force at different points on the button 11, resulting in a more consistent tactile feedback. Simultaneously, the free end 1512 of the elastic limiting member 151 provides elastic positioning for the button 11. When the button 11 moves, the free end 1512 of the elastic limiting member 151 does not slide relative to the button 11. In contrast, traditional rigid positioning methods using clips or positioning plates result in relative sliding between the button 11 and the housing 14, creating significant frictional resistance and causing a sticking sensation when pressing the button 11. This invention utilizes the elastic positioning scheme of the elastic limiting member 151, resulting in greater button 11 flexibility, less frictional force, and clearer pressing feedback.

[0145] Furthermore, the detection element 12 can be a micro switch, tactile switch, membrane switch, piezoelectric switch, or other switches that can be implemented by those skilled in the art; preferably, the detection element 12 is a micro switch, also known as a sensitive switch, commonly used in mouse buttons 11. Compared to tactile switches, micro switches have a smaller contact spacing, are easier to trigger, generally require only 60g of triggering force, and have a lighter trigger feedback with a smaller displacement during triggering. The structure of the micro switch in conjunction with the elastic limiting element 151 allows the slight trigger feedback of the micro switch to be transmitted, ensuring a smooth pressing feel while providing clear trigger feedback. Here, 60g can be understood as the weight of a 60-gram object.

[0146] like Figure 5The figure shows the pressure-displacement curve of button 11. The vertical axis represents the value of the control force, and the horizontal axis represents the displacement of button 11. The left side shows the curve when pressing the main pressing area of ​​button 11 (the middle position of button 11), and the right side shows the curve when pressing the corner position of button 11. Each side has two curves: the upper one is the curve when pressing, and the lower one is the curve when rebounding. As can be seen from the figure, at the first rebound position, the reaction force of button 11 is F3, and when button 11 rebounds from the first rebound position to the second rebound position, the reaction force jumps from F3 to F4. The structure of the elastic limiting member 151 is used in conjunction with the micro switch. The length of the elastic limiting member 151 is designed and calculated to ensure that F4>F3≥22g, which ensures that the button 11 has sufficient rebound force. The reaction force at the third rebound position is 0. Meanwhile, the displacement of the button 11 in the first rebound position is set as S1, and the displacement of the button 11 in the second rebound position is set as S2, and S1-S2≤2mm, so that when the detection element 12 changes from the triggered state to the non-triggered state, the displacement jump of the button 11 is smaller, making the pressing feedback crisper and improving the pressing feel. In a specific embodiment, as... Figure 5 As shown, S1-S2 < 0.2mm. Because the detection element 12 in this embodiment uses a micro switch, the trigger feedback is small, and the displacement during triggering is small. The structure of the micro switch in conjunction with the elastic limiting element 151 allows the slight trigger feedback of the micro switch to be transmitted, enabling the button 11 to achieve a smooth and clear pressing feel. If other detection elements 12 are used, such as tactile switches, the trigger feedback is larger, and S1-S2 may even exceed 1mm, resulting in a stronger pressing vibration and a less pleasant feel than the micro switch.

[0147] Furthermore, such as Figure 3 , Figure 4 and Figure 7 As shown, the free end 1512 is provided with a first positioning hole 1513. The button 11 has a corresponding protruding button positioning pin 111 at the first positioning hole 1513. The button positioning pin 111 is inserted into the first positioning hole 1513 to achieve a positioning connection between the button 11 and the free end 1512. The first positioning hole 1513 is a through hole, and the button positioning pin 111 is a cylindrical or frustum-shaped protrusion with a shaft diameter adapted to the diameter of the first positioning hole 1513. This allows the first positioning hole 1513 to restrict the horizontal displacement of the button positioning pin 111, thereby positioning the button 11. Positioning the button 11 has the following advantages: it ensures the relative positional accuracy between the button 11 and the detection element 12, preventing positional misalignment that could prevent the detection element 12 from being triggered; simultaneously, positioning the button 11 ensures consistent gaps between the buttons 11, improving aesthetics.

[0148] Furthermore, each button 11 corresponds to multiple elastic limiting members 151, and correspondingly, each button 11 also has multiple first positioning holes 1513 and button positioning pins 111. The button positioning pin 111 includes an integrally formed base of the button 11 and an end portion away from the base. The button positioning pin 111 is a frustum shape with a base diameter larger than an end diameter. Setting the button positioning pin 111 to a frustum shape with a base diameter larger than an end diameter facilitates insertion of the button positioning pin 111 into the first positioning hole 1513 and improves the positioning accuracy of the button 11. This is because, since each button 11 corresponds to multiple elastic limiting members 151, and each elastic limiting member 151 has a first positioning hole 1513, when the number of first positioning holes 1513 is three or more, each first positioning hole 1513 forms an over-positioning structure for the button 11. If the button positioning pin 111 is cylindrical, it will cause the button... The positioning pin 111 cannot be fully inserted into the first positioning hole 1513. The conventional solution is to increase the gap between the button positioning pin 111 and the first positioning hole 1513, but this will reduce the positioning accuracy. The button positioning pin 111 of the present invention adopts a frustum-shaped structure. The end of the frustum shape has a guiding function, so that the button positioning pin 111 can be smoothly inserted into the first positioning hole 1513. After insertion, as the button 11 approaches the housing 14, the gap between the button positioning pin 111 and the first positioning hole 1513 gradually decreases to achieve the effect of accurate positioning.

[0149] In a preferred implementation, such as Figure 7 As shown, the first positioning hole 1513 is a frustum-shaped hole, with its diameter on the side facing the button 11 being smaller than its diameter on the side away from the button 11. The button positioning pin 111 is inserted into the first positioning hole 1513 and then heat-fused to secure it. The smaller diameter of the first positioning hole 1513 on the side facing the button 11 ensures that the button positioning pin 111 is less likely to fall out after being heat-fused to the first positioning hole 1513. The advantage of using heat-fusion fixation is that it can further reduce the wobble between the button 11 and the upper housing 141, improve the stability of the button 11 when pressed, and further improve the positioning accuracy of the elastic limiting member 151.

[0150] Furthermore, such as Figure 8 and Figure 3As shown, in a first direction, the elastic limiting member 151 corresponding to each button 11 extends from the middle position of the button 11 toward the edge of the button 11. The first direction is parallel to one side of the button 11 and parallel to the upper surface of the button 11. The extension of the elastic limiting member 151 from the middle position of the button 11 toward the edge of the button 11 can be understood as the elastic limiting member 151 being integrally formed or fixedly connected to the housing 14. The housing 14 extends the elastic limiting member 151 from the middle position of the button 11 and extends toward the edge of the button 11, abutting against the edge of the button 11. This allows the reset force of each elastic limiting member 151 to act on the position of the button 11 near the edge, improving the stability of the support. The first direction is already... Figure 8 The arrow is used to indicate this.

[0151] Furthermore, each button 11 corresponds to four elastic limiting members 151. In the first direction, the four elastic limiting members 151 are symmetrically distributed in pairs; in the second direction, the four elastic limiting members 151 are arranged side-by-side in pairs. The second direction is parallel to the upper surface of the button 11 and perpendicular to the first direction. The first and second directions are as follows: Figure 8 As indicated by the middle arrow, the elastic limiting members 151 are symmetrically distributed in pairs and arranged side by side, so that the elastic limiting members 151 provide the button 11 with a symmetrical reset force, which can adapt to the combined motion of displacement and rotation of the button 11. The button 11 can tilt in multiple directions, and the symmetrical reset force provided by the elastic limiting members 151 can make the reset force received by the button 11 similar when it is tilted in any direction by the control force.

[0152] Meanwhile, the symmetrical reset force provided by the four elastic limiting members 151 makes it easy to control the reset force through structural design. By changing the angle, thickness, width, and length of the elastic limiting members 151, the applicant calculated and simulated to control the reset force to cooperate with the elastic force of the detection member 12, so that when the button 11 moves to the first pressing position, the reaction force is F1, and when the button 11 moves from the first pressing position to the second pressing position, the reaction force jumps from F1 to F2; where F2 < F1 < 400g; and the displacement S1 of the button 11 at the first pressing position and the displacement S2 at the second pressing position satisfy the relationship: S2 - S1 ≤ 2mm.

[0153] Furthermore, the extension direction of the elastic limiting member 151 is parallel to one side of the button 11, which reduces the space occupied by the elastic limiting member 151 in the second direction, leaving space for the housing 14 to arrange other components.

[0154] Furthermore, in combination Figure 8 and Figure 3 As shown, in the first direction, the length of the elastic limiting member 151 is greater than 1 / 4 of the length of the button 11. Since the four elastic limiting members 151 are symmetrically distributed in pairs in the first direction, and the elastic limiting members 151 extend from the middle position of the button 11 towards the edge position of the button 11, controlling the length of the elastic limiting member 151 to be greater than 1 / 4 of the length of the button 11 allows the elastic limiting member 151 to be as long as feasible. When the thickness of the elastic limiting member 151 remains unchanged, the longer its length, the better its flexibility and the less likely it is to break.

[0155] Furthermore, such as Figure 9 , Figure 4 and Figure 3 As shown, a reinforcing seat 116 is provided at the root of the button positioning pin 111. When the button positioning pin 111 is inserted into the first positioning hole 1513, the reinforcing seat 116 abuts against the elastic limiting member 151. Since the root of the button positioning pin 111 is prone to stress concentration and breakage, the reinforcing seat 116 at the root of the button positioning pin 111 prevents breakage at the root. In a specific embodiment, as... Figure 9 and Figure 10 As shown, the reinforcing seat 116 is configured with four reinforcing units 1161, which are evenly distributed circumferentially along the root of the button positioning pin 111. The reinforcing units 1161, the button positioning pin 111, and the button 11 are integrally formed. Specifically, the reinforcing unit 1161 is a square connecting block. The reinforcing seat 116 can strengthen the root of the button positioning pin 111 and prevent breakage. At the same time, the four reinforcing units 1161 are evenly distributed circumferentially along the button positioning pin 111, making it less prone to skewing during injection molding and cooling, thus improving the positioning accuracy of the button positioning pin 111.

[0156] Furthermore, such as Figure 7 As shown, the side of the elastic limiting member 151 facing the button 11 is parallel to the button 11 at the corresponding position of the first positioning hole 1513. That is, the upper surface of the free end 1512 of the elastic limiting member 151 is parallel to the lower surface of the button 11, so that the first positioning hole 1513 remains vertical during injection molding, facilitating the insertion of the button positioning pin 111 into the first positioning hole 1513 and improving the positioning accuracy of the first positioning hole 1513; at the same time, when the button positioning pin 111 is inserted into the first positioning hole 1513, the upper surface of the elastic limiting member 151 is in contact with the button 11 at the corresponding position of the first positioning hole 1513, and the elastic limiting member 151 and the button 11 are in surface contact, which improves the stability of the elastic limiting member 151 in supporting the button 11.

[0157] Furthermore, such as Figure 8 As shown, the elastic limiting member 151 extends from the housing 14, and the fixed end 1511 is integrally formed with the housing 14. Since the elastic limiting member 151 is integrally formed with the housing 14, no additional reset member is needed, simplifying the structure, reducing costs, decreasing the number of parts, and reducing assembly steps. Figure 7 As shown, the elastic limiting member 151 is a long strip-shaped sheet structure, and its thickness is less than the thickness of the shell 14, as... Figure 12 and Figure 8 As shown, the width at both ends is wider than the width in the middle. The elastic limiting member 151 can elastically deform in response to the pressure of the button 11, and the elastic deformation of the elastic limiting member 151 returns to its original state when the pressure is removed. The housing 14 needs to have a certain rigidity, while the elastic limiting member 151 needs to have a certain flexibility. Since the elastic limiting member 151 extends from the housing 14, its thickness is made thinner, so that while ensuring the rigidity of the housing 14, the elastic limiting member 151 has a certain degree of flexibility. The fact that the width at both ends is wider than the width in the middle can be understood as the width of the connection between the elastic limiting member 151 and the housing 14 at position 1197, as well as the width at the end, being wider in the second direction. Because the elastic limiting member 151 has a cantilever beam structure, the connection point with the housing 14 is prone to breakage. Therefore, controlling the width at both ends of the elastic limiting member 151 to be wider than the width in the middle strengthens the connection between the elastic limiting member 151 and the housing 14 at position 1197, preventing breakage due to excessive stress. Simultaneously, narrowing the width in the middle ensures the flexibility of the elastic limiting member 151. Furthermore, widening the end of the elastic limiting member 151 increases the size of the first positioning hole 1513, thereby increasing the diameter of the button positioning pin 111 and preventing breakage of the button positioning pin 111.

[0158] Furthermore, such as Figure 7 and Figure 8 As shown, the elastic limiting member 151 extends obliquely towards the button 11, and the side of the button 11 facing the housing 14 is designated as the first surface. The angle between the extending direction of the elastic limiting member 151 and the first surface of the button 11 is less than or equal to 40°. The first surface is... Figure 7On the lower surface of the middle button 11, an elastic limiting member 151 extends inclinedly towards the button 11, lifting the button 11 to a certain height, thus providing the button 11 with some downward movement space to ensure smooth triggering of the detection member 12. Simultaneously, since the elastic limiting member 151 abuts against the reinforcing seat 116 of the button positioning pin 111, the height of the upward tilt of the elastic limiting member 151 combined with the height of the reinforcing seat 116 equals the height the button 11 is lifted. Therefore, the upward tilt of the elastic limiting member 151 prevents the reinforcing seat 116 from becoming too high and tilted, affecting positioning accuracy. The angle between the extension direction of the elastic limiting member 151 and the first surface of the button 11 can be understood as... Figure 7 The angle between the extension direction of the elastic limiting member 151 and the upper surface of the housing 14 is less than or equal to 40° to prevent the elastic limiting member 151 from being difficult to bend or deform or from breaking during bending due to an excessively large angle. In a specific embodiment, the angle is equal to 7.9°.

[0159] In a preferred embodiment, the middle portion of the elastic limiting member 151 is bent at an arc (not shown in the figure), with the center of the arc facing away from the button 11. When the button 11 is pressed, it moves towards the housing 14, causing the elastic limiting member 151 to bend and deform towards the housing 14. During manufacturing, the middle portion of the elastic limiting member 151 is pre-bent at an arc with the arc facing away from the button 11, making the middle portion less prone to breakage when the elastic limiting member 151 undergoes this bending deformation.

[0160] Furthermore, such as Figure 7 and Figure 8 As shown, the connection between the elastic limiting member 151 and the housing 14 is a rounded transition. Since the elastic limiting member 151 is inclined towards the button 11, the connection between the elastic limiting member 151 and the housing 14 is a bending point, which is prone to stress concentration. Using a rounded transition at this point can reduce stress concentration and prevent the elastic limiting member 151 from breaking.

[0161] In another embodiment, the surface of the housing 14 facing the button 11 is designated as the second surface, and the extending direction of the elastic limiting member 151 is parallel to the second surface (not shown in the figure), and the surface of the elastic limiting member 151 facing the button 11 is coplanar with the second surface. The second surface is the upper surface of the housing 14. In this embodiment, the upper surface of the elastic limiting member 151 is parallel to and coplanar with the upper surface of the housing 14, causing the elastic limiting member 151 to extend horizontally from the housing 14. When the elastic limiting member 151 is subjected to downward pressure and bends, tearing points are less likely to occur, and the connection between the elastic limiting member 151 and the housing 14 is not bent in the vertical direction. Stress concentration at this connection point is reduced, making the elastic limiting member 151 less prone to breakage. Correspondingly, the height of the reinforcing seat 116 of the button positioning pin 111 is matched with the trigger displacement of the detection element 12, so that the reinforcing seat 116 abuts against the elastic limiting element 151 and raises the button 11 to a certain height, so that the button 11 has a certain pressing space to successfully trigger the detection element 12.

[0162] Furthermore, such as Figure 3 As shown, the housing 14 has a clearance portion 1411 on the side of the elastic limiting member 151 away from the button 11. The clearance portion 1411 is configured to have a shape adapted to the through hole or groove of the elastic limiting member 151. The elastic limiting member 151 deforms in response to the pressure of the button 11, and at least a portion of it is accommodated in the clearance portion 1411. The clearance portion 1411 on the side of the elastic limiting member 151 away from the button 11 can be understood as the clearance portion 1411 being formed on the upper surface of the housing 14 at a corresponding position on the elastic limiting member 151. The clearance portion 1411 being configured to have a shape adapted to the through hole or groove of the elastic limiting member 151 can be understood as the size of the clearance portion 1411 being slightly larger than the size of the elastic limiting member 151, so that the elastic limiting member 151 can be accommodated in the clearance portion 1411. In a specific embodiment, as... Figure 12 As shown, the elastic limiting member 151 includes a first side, a second side, and a third side. The housing 14 has a first strip-shaped through hole 1412 at a corresponding position on the first side, a second strip-shaped through hole 1413 at a corresponding position on the second side, and a third strip-shaped through hole 1414 at a corresponding position on the third side. The first strip-shaped through hole 1412 and the second strip-shaped through hole 1413 are opposite to each other, and the third strip-shaped through hole 1414 is opposite to the fixed end 1511 of the elastic limiting member 151. The first strip-shaped through hole 1412, the second strip-shaped through hole 1413, and the third strip-shaped through hole 1414 are interconnected to divide the housing 14 into the elastic limiting member 151. Figure 7 and Figure 3As shown, the elastic limiting member 151 is tilted upwards toward the button 11, so that the housing 14 forms the clearance portion 1411 at the corresponding position of the elastic limiting member 151. The elastic limiting member 151 is integrally injection molded from the housing 14. The first strip-shaped through hole 1412, the second strip-shaped through hole 1413, and the third strip-shaped through hole 1414 are formed by cutting during the injection molding of the housing 14. During injection molding, a space is reserved below the elastic limiting member 151, and the elastic limiting member 151 tilts upwards, forming the clearance portion 1411 below it.

[0163] In another embodiment, the button 11 has a first positioning groove (not shown in the figure) facing the elastic limiting member 151. The width and length of the first positioning groove are adapted to the width and length of the elastic limiting member 151, respectively. When the button 11 is installed on the housing 14, the first positioning groove is sleeved on the free end 1512 of the elastic limiting member 151, so that the first positioning groove is positioned by the elastic limiting member 151, thereby realizing the positioning connection between the button 11 and the free end 1512. Specifically, the elastic limiting member 151 is a rectangular strip structure, the button 11 has a certain thickness, and the first positioning groove is formed on the lower surface of the button 11. The first positioning groove is a rectangular groove with a size slightly larger than that of the elastic limiting member 151, so that the elastic limiting member 151 and the first positioning groove are in clearance fit, thereby allowing the first positioning groove to be completely sleeved on the elastic limiting member 151, and the elastic limiting member 151 abuts against the top wall of the first positioning groove. Furthermore, when the first limiting groove is fitted onto the elastic limiting member 151, the gap between the side wall of the elastic limiting member 151 and the side wall of the first limiting groove is less than 0.1 mm to prevent excessive gap from causing poor positioning accuracy. In another preferred embodiment, the first positioning groove is a trapezoidal shape with a lower opening size larger than the upper opening size, so that the first positioning groove fits onto the elastic limiting member 151, and the upper end of the first positioning groove and the elastic limiting member 151 adopt a transition fit. When the elastic limiting member 151 abuts against the top wall of the first positioning groove, the gap between the first positioning groove and the elastic limiting member 151 is reduced, thereby greatly increasing the positioning accuracy.

[0164] Furthermore, such as Figure 3 and Figure 9As shown, the button 11 is provided with a plurality of button clips 112 facing the housing 14. The housing 14 is provided with corresponding engagement positions 1415 for the button clips 112. The button clips 112 are engaged with the engagement positions 1415, thereby limiting the extreme position of the upward movement of the button 11. The button clips 112 extend integrally from the button 11, or the button clips 112 are fixedly connected to the button 11. The housing 14 is provided with a fastening position 1415 at a corresponding position of the key latch 112. This can be understood as the fastening position 1415 being located directly below the key latch 112, and the shape of the fastening position 1415 matching the end of the key latch 112, and slightly larger than the end of the key latch 112, so that the key latch 112 cannot detach after being fastened into the fastening position 1415. The multiple key latches 112 can be understood as each key 11 having three, four, six, eight, or other numbers of key latches 112, evenly distributed around the circumference of the key 11. Specifically, when there are three key latches 112, the key 11 can be set as a triangle (not shown in the figure), with the key latches 112 positioned at the three corners of the triangular key 11. When there are four key latches 112, the key 11 can be set as a quadrilateral, with the key latches 112 positioned at the four corners of the quadrilateral key 11. When there are six or eight button latches 112 (not shown in the figure), the button 11 can be set as a quadrilateral, with the button latches 112 symmetrically distributed on the four sides of the button 11. In this embodiment, the side of the button 11 facing the housing 14 is rectangular, and there are four button latches 112 distributed at the four corners of the rectangle, extending from the button 11 towards the housing 14. The placement of the button latches 112 at the four corners of the button 11 symmetrically restricts the button 11 at these corners, adapting to the combined displacement and rotational movements of the button 11. This facilitates the button 11 tilting in multiple directions. When one corner of the button 11 is subjected to a control force, that corner displaces downwards, and the button latches 112 diagonally distributed with that corner act as fulcrums, preventing the button 11 from tilting upwards and facilitating the triggering of the detection element 12. The symmetrical limiting provided by the button latches 112 ensures that the reset force experienced by the button 11 is similar when it tilts in different directions. Meanwhile, the button clips 112 are located at the four corners of the button 11, which makes the spacing between the button clips 112 larger. Due to the processing error, the height of each button clip 112 is incorrect, and the height of the latching position 1415 is also incorrect, which causes the upper surface of the button 11 to be not level. Increasing the distance between each button clip 112 can reduce the impact of the height error on the levelness of the upper surface of the button 11.

[0165] Furthermore, such as Figure 9 and Figure 10 As shown, the end of the button latch 112 is provided with a hook portion 1121. The button latch 112 is hooked to the lower edge of the fastening position 1415 through the hook portion 1121 to limit the extreme position of the upward movement of the button 11. The orientation of the hook portion 1121 is set from the four corners of the button 11 to the center of the button 11. The hook portion 1121 can be understood as a hook-shaped structure extending laterally from the end of the button latch 112. When the button latch 112 is fastened into the fastening position 1415, the hook-shaped structure of the hook portion 1121 hooks the lower edge of the fastening position 1415, so that the button latch 112 cannot disengage from the fastening position 1415 upwards. When the corner of button 11 is pressed, the button latch 112 located diagonally opposite the pressing area acts as a fulcrum and is inclined towards the outside of button 11. The hook portion 1121 facing the inside of button 11 can prevent the button latch 112 from interfering with the housing 14, thus affecting the pressing feel. Furthermore, the hook portion 1121 is inclined relative to the side of button 11, so that the four button latches 112 cooperate with each other to restrict the horizontal displacement and rotation of button 11, thus positioning button 11. Since the positioning accuracy of button latch 112 is relatively low, if the positioning function of button latch 112 is relied on only, without the use of elastic limiting member 151 for limiting, button 11 can make a small distance displacement in the horizontal direction, resulting in uneven gaps between buttons 11. It is necessary to reduce the fit gap between button latch 112 and housing 14 to improve the positioning accuracy of button latch 112. This will increase the friction between button latch 112 and housing 14, increasing the pressing resistance. This invention uses a button latch 112 in conjunction with an elastic limiting member 151. The button latch 112 pre-positions the button positioning pin 111 so that it aligns with the first positioning hole 1513 of the elastic limiting member 151. This facilitates the insertion of the button positioning pin 111 into the first positioning hole 1513. The elastic limiting member 151 serves as the main positioning element, which not only improves the positioning accuracy of the buttons 11 and ensures consistent gaps between the buttons 11, but also prevents friction between the button latch 112 and the housing 14, thus avoiding increased resistance and a sticky feeling when pressing the buttons 11.

[0166] Furthermore, such as Figure 10As shown, the side of the button 11 facing the housing 14 is designated as a first surface. The projection of the button latch 112 onto the first surface is a first arc shape, with the center of the first arc pointing towards the center of the button 11 and towards the button latch 112. Correspondingly, the projection of the hook portion 1121 onto the first surface is a second arc shape, with the center of the second arc shape being at the same position as the center of the first arc shape. The use of an arc-shaped latch further prevents the button 11 from detaching from the housing 14 and provides symmetrical positioning for the button 11 to accommodate pressing from various directions. Correspondingly, the projection of the engaging position 1415 of the housing 14 onto the upper surface of the housing 14 is a fan shape, and the arc edge of the fan shape matches the arc shape of the button latch 112; as... Figure 3 As shown, the latching position 1415 is a through hole, and a first guide slope 14151 is provided on the side facing the button 11 at the arc of the fan shape, so that the button buckle 112 can be latched into the latching position 1415.

[0167] Furthermore, such as Figure 11 As shown, the housing 14 has a latching space 1421 at the corresponding position of the latching position 1415. The space is configured as a groove with a shape adapted to the latching position 1415 to prevent the button latch 112 from interfering with the housing 14 during movement. Specifically, the housing 14 includes an upper housing 141 and a lower housing 142. The button 11 is disposed in the upper housing 141. Correspondingly, the upper housing 141 passes through the latching position 1415. The lower housing 142 has a groove with a shape matching the button latch 112 below the latching position 1415 to form the latching space 1421.

[0168] Furthermore, such as Figure 3 , Figure 6 and Figure 9As shown, the button 11 has a contact portion 113 at a corresponding position on the detection element 12. When the button 11 responds to the operating force and generates the displacement, the contact portion 113 directly or indirectly presses against and triggers the detection element 12. This can be understood as the contact portion 113 being positioned above the detection element 12, allowing direct pressure on it; or a waterproof silicone sleeve being provided between the contact portion 113 and the detection element 12, indirectly triggering the detection element 12 by pressing against the waterproof silicone sleeve; or a buffer being provided between the contact portion 113 and the detection element 12, with the contact portion 113 triggering the detection element 12 through the buffer, which prevents excessive pressure from the button 11 from damaging the detection element 12. Specifically, the detection element 12 is located below the center of the button 11, and the contact portion 113 extends downwards from the center of the button 11 towards the housing 14. Furthermore, in the third direction, the length of the button latch 112 is adapted to the length of the contact portion 113, such that when the button 11 does not produce the displacement, the gap between the contact portion 113 and the detection element 12 is less than or equal to 1.5mm; the third direction is the direction in which the button 11 points towards the housing 14. When the button 11 is not pressed, the button latch 112 hooks onto the engagement position 1415 to restrict the upward movement of the button 11, preventing the button 11 from detaching from the housing 14. The gap between the contact portion 113 and the detection element 12 is less than or equal to 1.5mm, that is, the downward travel of the button 11 is less than or equal to 1.5mm, improving the pressing feel of the button 11. In this embodiment, the gap between the contact portion 113 and the detection element 12 is set to 0.1mm. The purpose of leaving a gap between the contact portion 113 and the detection element 12 is to prevent assembly errors from causing the detection element 12 to be pre-pressed, or even leading to false triggering. Furthermore, the limit value of the displacement generated by the button 11 is greater than or equal to 1.2 mm. When the displacement reaches the limit value, at least a portion of the button 11 abuts against the housing 14. In this embodiment, the edge of the button 11 extends towards the housing 14 to form a button 11 enclosure portion, and the button 11 enclosure portions surround each other to cover a portion of the housing 14; wherein, in the third direction, the distance between the button 11 enclosure portion and the housing 14 is greater than or equal to 1.2 mm, such that the limit value of the displacement generated by the button 11 is greater than or equal to 1.2 mm.The button 11 surrounds a portion of the housing 14, improving its aesthetics. In this embodiment, the gap between the button 11 surround and the housing 14 is controlled so that the maximum downward stroke of the button 11 is 1.6mm. If the edge of the button 11 is pressed, according to the lever principle, pressing the edge of the button 11 by 1.6mm will cause the contact part 113 to press down by 0.8mm. The detection element 12 uses a micro switch with a theoretical trigger stroke of 0.3mm. Theoretically, pressing the contact part 113 down by 0.4mm will trigger the detection element 12. In actual production, the cumulative assembly tolerance and deformation of the button 11 may increase the reserved 0.1mm gap. Therefore, in the theoretical design, the downward stroke of the contact part 113 at the edge of the button 11 is designed to be 0.8mm. The extra 0.4mm downward stroke ensures that the detection element 12 can still be successfully triggered when the edge of the button 11 is pressed.

[0169] Furthermore, such as Figure 9 and Figure 10 As shown, the contact portion 113 is a column extending from the button 11 toward the detection element 12. Its cross-section perpendicular to the extension direction is designated as a first cross-section, which is composed of two intersecting and perpendicular rectangles. The first shape can be understood as a cross shape, which serves to prevent shrinkage caused by localized thickening of the glue in the contact portion 113 during injection molding, thus preventing the detection element 12 from being triggered.

[0170] In another embodiment, such as Figure 30 , Figure 31 and Figure 32 As shown, the free end 1512 of the elastic limiting member 151 extends towards the detection member 12 with a contact portion 113. When the button 11 responds to the operating force and generates the displacement, the button 11 presses against the elastic limiting member 151 and undergoes the deformation. The elastic limiting member 151 drives the contact portion 113 to trigger the detection member 12. In this embodiment, there is one elastic limiting member 151 corresponding to each button 11. The elastic limiting member 151 is a cantilever beam structure and is tilted towards the button 11. The contact portion 113 extends from the end of the elastic limiting member 151. Figure 31 and Figure 32As shown, the elastic limiting member 151 has a receiving portion 1514 protruding from the corresponding position of the contact portion 113 toward the button 11. The receiving portion 1514 is configured as an arc-shaped protrusion for abutting against the button 11 and causing the elastic limiting member 151 to generate the deformation. When the button 11 generates the displacement in response to the operating force, the lower surface of the button 11 presses against and drives the contact portion 113 to trigger the detection member 12. The beneficial effects of this embodiment are as follows: the contact part 113, the elastic limiting member 151, and the housing 14 are integrally formed, ensuring the relative positional accuracy between the contact part 113 and the housing 14. Since the detection member 12 is mounted on the housing 14, the positioning accuracy between the contact part 113 and the detection member 12 is guaranteed. Compared to placing the contact part 113 on the button 11, this embodiment places the contact part 113 on the elastic limiting member 151, shortening the error dimension chain between the contact part 113 and the detection member 12, making it easier to ensure the positioning accuracy between the contact part 113 and the detection member 12, thereby reducing the manufacturing precision requirements. Furthermore, no positioning relationship is needed between the button 11 and the detection member 12, reducing the positioning accuracy requirement of the button 11. No positioning structure is needed between the button 11 and the elastic limiting member 151, further reducing the manufacturing cost of the button 11 and the elastic limiting member 151.

[0171] Meanwhile, because the relative positional accuracy between the contact part 113 and the detection element 12 in the above structure is controlled very highly, and a single elastic limiting element 151 is used to provide the reset force, the reset force is easy to control and can be calculated. Furthermore, since the elastic limiting element 151 is a cantilever beam structure, the calculated reset force has high reliability. By changing the tilt angle, thickness, width, and length of the elastic limiting element 151, and through calculation and simulation, the applicant controls the reset force to cooperate with the elastic force of the detection element 12, so that when the button 11 moves to the first pressing position, the reaction force is F1, and when the button 11 moves from the first pressing position to the second pressing position, the reaction force jumps from F1 to F2; where F2 < F1 < 400g; and the displacement S1 of the button 11 at the first pressing position and the displacement S2 at the second pressing position satisfy the relationship: S2 - S1 ≤ 2mm.

[0172] Furthermore, the upper housing 141 has a light-transmitting hole 1419 for the light-diffusing mask at a corresponding position on the detection element 12, and the contact part 113 can pass through the light-diffusing mask light-transmitting hole 1419 and abut against the detection element 12. The light-diffusing mask light-transmitting hole 1419 also allows the light-diffusing mask 183 to pass through; the technical details of the light-diffusing mask 183 and the light-diffusing mask light-transmitting hole 1419 are described in detail below.

[0173] In this embodiment, there is no positioning structure between the button 11 and the elastic limiting member 151; the button 11 is positioned by the housing 14. Specifically, as shown below... Figure 30and Figure 33 As shown, the button 11 is provided with four button latches 112 facing the housing 14. Each button latch 112 has a hook portion 1121 at its end. The housing 14 has corresponding engagement positions 1415 adapted to the button latches 112. When the button latch 112 is engaged with the engagement position 1415, the button latch 112 hooks the edge of the engagement position 1415 through the hook portion 1121, thus limiting the maximum upward movement of the button 11. The hook portions 1121 of any two adjacent button latches 112 are perpendicular to each other. This can be understood as the hook portions 1121 of the four button latches 112 being oriented opposite each other, and the hook portions 1121 of two adjacent button latches 112 being perpendicular to each other. Specifically, the upper surface of button 11 is square, and there are four button latches 112 distributed at the four corners of button 11. The corresponding hooks 1121 of the four button latches 112 are set from the four corners of button 11 toward the center of button 11. Thus, the four button latches 112 mutually restrict and cooperate with each other in the horizontal direction, which can limit the horizontal displacement and rotation of button 11, so that the housing 14 positions button 11.

[0174] In another embodiment, such as Figures 34-37 As shown, the reset part 15 is configured with at least one elastic reset member 152. The elastic reset member 152 is disposed between the button 11 and the housing 14, and can elastically deform in response to the displacement of the button 11, generating a reset force to overcome the elastic deformation. The elastic reset member 152 can be understood as an elastic component, including but not limited to springs, torsion springs, spring sheets, elastic foam, silicone, etc. The placement of the elastic reset member 152 between the button 11 and the housing 14 can be understood as follows: the elastic reset member 152 is installed on the button 11 or the housing 14, and is clamped between the button 11 and the housing 14. The elastic reset member 152 simultaneously abuts against the lower surface of the button 11 and the upper surface of the housing 14. When the button 11 presses against the elastic reset member 152, the elastic deformation occurs, and the elastic reset member 152 generates a reset force to overcome the elastic deformation, supporting the button 11 to return to its initial position.

[0175] Furthermore, such as Figure 35 and Figure 36As shown, the elastic reset member 152 is a spring 1521; the button 11 extends a spring limiting portion 118 towards the housing 14 at a position opposite to the spring 1521, and the spring 1521 is sleeved on the spring limiting portion 118, so that the spring 1521 is limited in the horizontal direction. The spring limiting portion 118 can be understood as a column extending downward from the button 11, the size of which is slightly smaller than the inner diameter of the spring 1521, so that the spring 1521 is sleeved on the spring limiting portion 118 and limited.

[0176] Furthermore, such as Figure 36 As shown, the side of the button 11 facing the housing 14 is rectangular. Four spring limiting portions 118 are distributed at the four corners of the rectangle. Correspondingly, four springs 1521 are also present, each fitted onto one of the four spring limiting portions 118. The spring limiting portions 118, distributed at the four corners of the rectangle, can provide balanced support for the button 11, adapting to the combined displacement and rotational movements of the button 11. The button 11 can tilt in multiple directions, and the symmetrical reset force provided by the elastic reset member 152 ensures that the reset force is similar regardless of which direction the button 11 is tilted by the control force.

[0177] Meanwhile, since the elastic force provided by spring 1521 is proportional to the compression amount, and the symmetrical reset force provided by the four springs 1521 makes the reset force easy to control and calculate, the applicant controlled the elastic force of spring 1521 by testing the elastic coefficient of various types of springs 1521. Through calculation and simulation, the reset force was controlled to cooperate with the elastic force of the detection element 12, so that when the button 11 moves to the first pressing position, the reaction force is F1, and when the button 11 moves from the first pressing position to the second pressing position, the reaction force jumps from F1 to F2; where F2 < F1 < 400g; and the displacement S1 of the button 11 at the first pressing position and the displacement S2 at the second pressing position satisfy the relationship: S2 - S1 ≤ 2mm.

[0178] Furthermore, such as Figure 35 and Figure 37As shown, the housing 14 has a clearance 143 at a corresponding position of the spring limiting part 118. When the button 11 responds to the operating force and generates the displacement, the button 11 drives the spring limiting part 118 to move. The clearance 143 provides clearance space at a corresponding position of the spring limiting part 118 to prevent interference between the spring limiting part 118 and the housing 14. The clearance 143 can be understood as a through hole in the housing 14 whose shape is adapted to the spring limiting part 118. The spring limiting part 118 is inserted into the clearance 143 and can move within it. Specifically, the spring limiting part 118 is a cylinder, and the clearance 143 is a cylindrical through hole. A certain gap is provided between the inner wall of the clearance 143 and the side wall of the spring limiting part 118 to prevent interference between the clearance 143 and the spring limiting part 118 when the button 11 is pressed at an angle. However, the gap between the clearance 143 and the spring limiting part 118 should not be too large, because the clearance 143 has a positioning function for the spring limiting part 118, positioning the button 11 and making the gaps between the buttons uniform. In a specific embodiment, the gap between the inner wall of the clearance 143 and the side wall of the spring limiting part 118 is set to 0.2 mm.

[0179] Furthermore, such as Figure 35 and Figure 36 As shown, the end of the spring limiting part 118 facing the button 11 is press-fitted with the spring 1521, while the end of the spring limiting part 118 away from the button 11 is clearance-fitted with the spring 1521. The press-fit between the end of the spring limiting part 118 facing the button 11 and the spring 1521 ensures that after the spring 1521 is fitted onto the spring limiting part 118, the end of the spring 1521 facing the button 11 is secured to the root of the spring limiting part 118, preventing the spring 1521 from falling off during assembly, thus facilitating the installation of the button 11 onto the housing 14. Conversely, the clearance-fit between the end of the spring limiting part 118 away from the button 11 and the spring 1521 ensures that the spring 1521 does not interfere with the spring limiting part 118 when compressed, guaranteeing the smoothness of the spring 1521's compression and recovery. In one specific embodiment, as... Figure 35 As shown, the spring limiting part 118 is cylindrical, and the spring 1521 is a frustum shape with an upper diameter smaller than a lower diameter. Its upper end is positioned facing the button 11, and its lower end is positioned away from the button 11. The upper diameter of the spring 1521 is smaller than the shaft diameter of the spring limiting part 118, so that the upper end of the spring 1521 is in an interference fit with the spring limiting part 118. The lower diameter of the spring 1521 is larger than the shaft diameter of the spring limiting part 118, so that the lower end of the spring 1521 is in a clearance fit with the spring limiting part 118.

[0180] In another specific embodiment, the spring 1521 is cylindrical (not shown in the figure), and the spring limiting part 118 is a frustum-shaped part with an upper diameter larger than its lower diameter. Its upper end is positioned facing the button 11, and its lower end is positioned away from the button 11. The diameter of the upper end of the spring limiting part 118 is larger than the shaft diameter of the spring limiting part 118, so that the upper end of the spring limiting part 118 is in an interference fit with the spring 1521. The diameter of the lower end of the spring limiting part 118 is smaller than the shaft diameter of the spring 1521, so that the lower end of the spring limiting part 118 is in a clearance fit with the spring 1521.

[0181] Furthermore, such as Figure 37 and Figure 35 As shown, the button 11 is provided with four button latches 112 facing the housing 14. Each button latch 112 has a hook portion 1121 at its end. The housing 14 has corresponding engagement positions 1415 adapted to the button latches 112. When the button latch 112 is engaged with the engagement position 1415, the button latch 112 hooks the edge of the engagement position 1415 through the hook portion 1121, thus limiting the maximum upward movement of the button 11. The hook portions 1121 of any two adjacent button latches 112 are perpendicular to each other. This can be understood as the hook portions 1121 of the four button latches 112 being oriented opposite each other, and the hook portions 1121 of two adjacent button latches 112 being perpendicular to each other. Specifically, the upper surface of button 11 is square, and there are four button latches 112 distributed at the four corners of button 11. The corresponding hook portions 1121 of the four button latches 112 are set from the four corners of button 11 toward the center of button 11. Thus, the four button latches 112 mutually restrict and cooperate in the horizontal direction, which can limit the horizontal displacement and rotation of button 11, so that button 11 is positioned by button latches 112. Although the clearance 143 on housing 14 has a positioning function for button 11, the positioning accuracy is not high due to the large gap between clearance 143 and the side wall of spring limiting part 118. Therefore, the positioning function of button latches 112 is combined to improve the positioning accuracy of housing 14 for button 11.

[0182] Furthermore, such as Figure 34As shown, the length of the spring 1521 matches the length of the button latch 112, so that when the button 11 is not displaced, the spring 1521 is in a compressed state. Matching the length of the spring 1521 with the length of the button latch 112 can be understood as the spring 1521 being clamped between the button 11 and the housing 14, while the length of the button latch 112 determines the distance between the button 11 and the housing 14. Controlling the length of the button latch 112 ensures that the distance between the button 11 and the housing 14 is less than the length of the spring 1521 in its natural state, thus keeping the spring 1521 compressed when installed between the button 11 and the housing 14. The beneficial effect is that the spring 1521 provides preload to the button 11, ensuring that the button 11 is still supported by the spring 1521 when not pressed, guaranteeing that the button 11 is in its upper limit position when not pressed, improving the flatness of the upper surface of each button 11, and increasing the tightness of the button 11, preventing it from becoming loose.

[0183] Furthermore, such as Figure 36 As shown, the button 11 has a contact portion 113 at a corresponding position on the detection element 12. When the button 11 responds to the operating force and generates the displacement, the contact portion 113 directly or indirectly presses against and triggers the detection element 12. Furthermore, in the third direction, the length of the button latch 112 is adapted to the length of the contact portion 113, such that when the button 11 does not generate the displacement, the gap between the contact portion 113 and the detection element 12 is less than or equal to 1.5 mm; the third direction is the direction in which the button 11 points towards the housing 14, i.e. Figure 35 The direction indicated by the middle arrow. The structural features and technical details of the contact portion 113 have been described previously and will not be repeated here.

[0184] In another embodiment, such as Figures 38-41As shown, the button 11 includes a function cover 1191 and a surface cover 1192. The surface cover 1192 at least partially covers the function cover 1191 and is fixedly connected to the function cover 1191. The function cover 1191 is movably connected to the housing 14 and can directly or indirectly press against and trigger the detection element 12. The surface cover 1192 can be understood as the outer cover of the button 11, covering the outer surface of the function cover 1191 for contact with the user's fingers, improving the tactile feel and aesthetics of the button 11. The function cover 1191 can be understood as the inner cover of the button 11, movably connected to the housing 14, for realizing the movement of the button 11 and triggering the detection element 12. Furthermore, the surface cover 1192 and the function cover 1191 are made of different materials. The surface cover 1192 uses a material that improves tactile feel or aesthetics, such as metal, glass, or AG frosted panel, while the function cover 1191 uses injection-molded hard plastic. The surface cover 1192 and the functional cover 1191 are fixedly connected by means of adhesive or double-sided tape, snap fasteners, sliding track snap fasteners, or other connection methods that can be implemented by those skilled in the art.

[0185] In some embodiments, such as Figures 38-41 As shown, the reset part 15 is configured as a spring 153. The spring 153 includes a clamping part 1531 located in the middle and deformable parts 1532 located at both ends of the clamping part 1531. The clamping part 1531 is clamped between the functional cover 1191 and the surface cover 1192. The deformable parts 1532 are bent toward the housing 14. When the button 11 produces the displacement, the deformable parts 1532 are pressed by the housing 14 and undergo elastic deformation, generating the reset force that overcomes the elastic deformation. The clamping part 1531 being clamped between the functional cover 1191 and the surface cover 1192 can be understood as the surface cover 1192 being attached to the upper surface of the functional cover 1191, and the clamping part 1531 being disposed between the surface cover 1192 and the functional cover 1191. The deformable part 1532 bending towards the housing 14 can be understood as the deformable parts 1532 located at both ends of the spring 153 bending obliquely towards the housing 14, and the functional cover 1191 having through holes at corresponding positions of the deformable parts 1532, so that the deformable parts 1532 can pass through the through holes of the functional cover 1191 and abut against the surface of the housing 14. The deformable part 1532 undergoing elastic deformation under pressure from the housing 14 can be understood as the spring 153 being made of an elastic material. In this embodiment, the spring 153 is made of spring steel 1521, which can be pressed and undergo elastic deformation, generating a restoring force.

[0186] In this embodiment, the deformable portion 1532 of the spring 153 provides a reset force through compressive deformation. The factors affecting this reset force are relatively few, making it easy to control the reset force through structural design. By changing the tilt angle, thickness, width, and length of the spring 153, the applicant, through calculation and simulation, controls the reset force to cooperate with the elastic force of the detection element 12, so that when the button 11 moves to the first pressing position, the reaction force is F1, and when the button 11 moves from the first pressing position to the second pressing position, the reaction force jumps from F1 to F2; wherein, F2 < F1 < 400g; and the displacement S1 of the button 11 at the first pressing position and the displacement S2 at the second pressing position satisfy the relationship: S2 - S1 ≤ 2mm.

[0187] In one specific embodiment, such as Figure 38 and Figure 39 As shown, the functional cover 1191 is recessed with a clamping part placement groove 1193 facing the clamping part 1531. The shape of the clamping part placement groove 1193 can accommodate the clamping part 1531, and the depth of the clamping part placement groove 1193 is greater than or equal to the thickness of the clamping part 1531, so that when the surface cover 1192 is placed on the functional cover 1191, the surface cover 1192 and the functional cover 1191 are in close contact. The close contact between the surface cover 1192 and the functional cover 1191 can be understood as follows: when the surface cover 1192 is placed on the functional cover 1191, the surface cover 1192 is not pushed up by the clamping part 1531, and the lower surface of the surface cover 1192 can be in contact with the upper surface of the functional cover 1191.

[0188] Furthermore, such as Figure 38 and Figure 39As shown, the clamping portion 1531 of the spring 153 has at least one positioning through hole 1533. The functional cover 1191 has a positioning boss 1194 protruding at the corresponding position of the positioning through hole 1533. The size of the positioning boss 1194 is adapted to the positioning through hole 1533, so that the positioning boss 1194 is inserted into the positioning through hole 1533 to position the spring 153. The positioning boss 1194 can be understood as a cylindrical boss protruding from the functional cover 1191 toward the surface cover 1192. The diameter of the positioning through hole 1533 is adapted to the outer diameter of the positioning boss 1194, so that the positioning through hole 1533 is fitted onto the positioning boss 1194, allowing the spring 153 to be positioned horizontally by the button 11. The positioning through hole 1533 and the positioning boss 1194 use a transition fit or a small clearance fit to improve positioning accuracy. When there is only one positioning through hole 1533, the cooperation between the positioning through hole 1533 and the positioning boss 1194 can only restrict the horizontal displacement freedom of the spring 153, but not its horizontal rotational freedom. Therefore, the width of the clamping part placement groove 1193 needs to be adapted to the width of the clamping part 1531 to restrict the horizontal rotational freedom of the spring 153. Since the spring 153 is clamped between the surface cover 1192 and the functional cover 1191, its vertical displacement and rotational freedom are restricted.

[0189] Furthermore, such as Figure 38 and Figure 39 As shown, there are at least two positioning through holes 1533, which are arranged at intervals along the long side of the clamping part 1531. When there are two or three positioning through holes 1533, the horizontal displacement and horizontal rotational freedom of the spring 153 can be restricted by the cooperation of the two positioning through holes 1533 and the corresponding two positioning bosses 1194. Since the spring 153 is clamped between the surface cover 1192 and the functional cover 1191, its vertical displacement and rotational freedom are restricted, and thus all the freedom of the spring 153 is restricted by the surface cover 1192 and the functional cover 1191.

[0190] Furthermore, such as Figure 39 and Figure 40As shown, the end of the deformable portion 1532 is attached to the upper surface of the housing 14, which is the side of the housing 14 facing the button 11. The attachment of the end of the deformable portion 1532 to the upper surface of the housing 14 can be understood as the end of the deformable portion 1532 being bent horizontally, making it parallel to the upper surface of the housing 14. The beneficial effect is that, since the restoring force provided by the spring 153 is generated by pressing against the deformation of the spring 153, the end of the deformable portion 1532 will slide outward relative to the housing 14 when the spring 153 deforms. If the deformable portion 1532 is tilted towards the housing 14, the end of the deformable portion 1532 will... Scraping the upper surface of the housing 14 like a shovel would create significant sliding resistance, resulting in high resistance when pressing the button 11 and causing considerable wear to the upper surface of the housing 14. Therefore, in this embodiment, the end of the deformable part 1532 is parallel to the upper surface of the housing 14, so that the end of the deformable part 1532 fits against the upper surface of the housing 14, changing from line contact to surface contact. This reduces contact stress and decreases the sliding resistance of the end of the deformable part 1532, making the button 11 smoother to press and reducing wear on the upper surface of the housing 14.

[0191] Furthermore, a wear-resistant component (not shown in the figure) is provided at the part of the housing 14 that contacts the spring 153. When the button 11 is moved, the end of the spring 153 presses against the wear-resistant component and moves relative to the wear-resistant component. The wear-resistant component provided at the contact point between the housing 14 and the spring 153 can be understood as follows: the wear-resistant component is fixedly attached to the upper surface of the housing 14, including by bonding or snapping it onto the upper surface of the housing 14. The wear-resistant component is made of materials such as metal sheet, glass sheet, or wear-resistant plastic, and its surface has high wear resistance. When the button 11 is moved, the button 11 compresses the spring 153, causing the deformable part 1532 to undergo elastic deformation. The end of the deformable part 1532 slides on the upper surface of the housing 14. Since the spring 153 is generally made of hard metal, it will cause wear to the upper surface of the housing 14. Therefore, a wear-resistant component is provided at the contact point between the spring 153 and the housing 14. The spring 153 abuts against the surface of the wear-resistant component to prevent wear on the upper surface of the housing 14. At the same time, the surface of the wear-resistant component is smoother, which can further improve the smoothness of pressing the button 11.

[0192] Furthermore, such as Figure 41 and Figure 38As shown, the button 11 has multiple button latches 112 facing the housing 14. The housing 14 has corresponding engagement positions 1415 for each button latch 112. The button latches 112 engage with the engagement positions 1415, thus limiting the maximum upward movement of the button 11. Furthermore, the side of the button 11 facing the housing 14 is rectangular, and four button latches 112 are distributed at the four corners of the rectangle, extending from the button 11 towards the housing 14. Each button latch 112 cooperates to restrict two displacement degrees of freedom and one rotational degree of freedom of the button 11 in the horizontal direction. The structural features and technical details of the button latches 112 have been described previously and will not be repeated here.

[0193] Furthermore, such as Figure 40 As shown, the length of the button latch 112 is adapted to the bending height of the deformable portion 1532 towards the housing 14, so that when the button 11 does not undergo the displacement, the end of the deformable portion 1532 presses against the housing 14. The adaptation of the length of the button latch 112 to the bending height of the deformable portion 1532 can be understood as follows: the deformable portion 1532 of the spring 153 bends towards the housing 14, the clamping portion 1531 of the spring 153 is fixed to the button 11, and the end of the deformable portion 1532 abuts against the upper surface of the housing 14. The deformable portion 1532 is clamped between the button 11 and the housing 14, and the length of the button latch 112 determines the distance between the button 11 and the housing 14. By controlling the length of the button latch 112, the distance between the button 11 and the housing 14 is less than the bending height of the deformable portion 1532 of the spring 153 in its natural state, so that when the button 11 is installed on the housing 14, the deformable portion 1532 of the spring 153 is in a state of being pressed and deformed. The beneficial effect is that the spring 153 has a preload force on the button 11, so that the button 11 is still supported by the spring 153 when it is not pressed, ensuring that the button 11 is in the upper limit position when it is not pressed, improving the flatness of the upper surface of each button 11, and improving the tightness of the button 11, so that it will not be loose.

[0194] Furthermore, such as Figure 41 As shown, the button 11 has a contact portion 113 at a corresponding position on the detection element 12. When the button 11 responds to the operating force and generates the displacement, the contact portion 113 directly or indirectly presses against and triggers the detection element 12. Furthermore, in the third direction, the length of the button latch 112 is adapted to the length of the contact portion 113, such that when the button 11 does not generate the displacement, the gap between the contact portion 113 and the detection element 12 is less than or equal to 1.5 mm; the third direction is the direction in which the button 11 points towards the housing 14, i.e. Figure 40 The direction indicated by the middle arrow. The structural features and technical details of the contact portion 113 have been described previously and will not be repeated here.

[0195] In some implementations, such as Figure 43 As shown, the button 11 is pivotally connected to the housing 14 to restrict three displacement degrees of freedom and two rotational degrees of freedom of the button 11. The button 11 responds to the control force and pivots based on the housing 14, triggering the detection element 12 during the movement. The pivotal connection between the button 11 and the housing 14 can be understood as the button 11 being able to rotate about a rotation axis of the housing 14. Specific structures include: shaft-hole type pivotal connection, snap-fit ​​type pivotal connection, abutment type pivotal connection, etc., as described below. The triggering of the detection element 12 during the movement of the housing 14 can be understood as the detection element 12 being positioned at the trajectory point of the pivotal movement of the housing 14, causing the housing 14 to press against the detection element 12 during the pivotal movement, thereby triggering the detection element 12.

[0196] In this embodiment, button 11 is pivotally connected to housing 14. Button 11 is equivalent to a lever, and its force relationship is relatively simple. Only the reset force needs to be calculated to obtain the corresponding reaction force. The reset force provided by the elastic arm is easy to control through structural design. The applicant can control the reaction force by controlling the reset force of the elastic arm. Through calculation and simulation, the reset force is controlled to cooperate with the elastic force of the detection element 12 so that when button 11 moves to the first pressing position, the reaction force is F1, and when button 11 moves from the first pressing position to the second pressing position, the reaction force jumps from F1 to F2; where F2 < F1 < 400g; and the displacement S1 of button 11 at the first pressing position and the displacement S2 of button 11 at the second pressing position satisfy the relationship: S2 - S1 ≤ 2mm.

[0197] Furthermore, such as Figure 42 and Figure 43 As shown, the button 11 is pivotally connected to the housing 14 at its middle position, and both ends of the button 11 can receive the operating force to generate the pivoting movement. The housing 14 is provided with detection elements 12 at both ends of the button 11. Both ends of the button 11 can be pressed to trigger the corresponding detection element 12. The advantage of this design is that one button 11 corresponds to two pressing functions at both ends, saving the number of buttons 11 and allowing the switch to achieve more pressing functions within the limited space of the button 11 panel.

[0198] In another embodiment, one end of the button 11 is pivotally connected to the housing 14 (not shown in the figure), and the other end can receive the operating force to generate the pivoting movement. The advantage of this design is that the area of ​​the button 11 that is pressed is increased, reducing the risk of accidental activation. Simultaneously, the button 11 acts as a lever, and placing the pivot at the end of the button 11 lengthens the power arm, improving the pressing feel.

[0199] Furthermore, such as Figure 42 As shown, the button 11 has a contact portion 113 facing the detection element 12. The button 11 responds to the operating force and pivots based on the housing 14, causing the contact portion 113 to directly or indirectly press against and trigger the detection element 12. The structural features and technical details of the contact portion 113 have been described above and will not be repeated here.

[0200] In some embodiments, such as Figure 42 and Figure 43 As shown, a pivot shaft and a pivot hole (not shown) with clearance fit are provided between the button 11 and the housing 14. One of the pivot shaft and the pivot hole is located in the button 11, and the other is located in the housing 14. The pivot shaft is inserted into the pivot hole, allowing the button 11 to pivot based on the pivot shaft. In a specific embodiment, pivot shafts protrude from both sides of the button 11, and the central axes of the two pivot shafts are collinear. The inner surface of the housing 14 has pivot holes recessed at corresponding positions of the two pivot shafts. The pivot holes and pivot shafts are clearance fit, allowing the pivot shafts to rotate within the pivot holes. A guide slope is provided at the lower end of the pivot shaft, allowing the pivot shaft to be engaged with the pivot hole from top to bottom.

[0201] In some embodiments, such as Figure 42As shown, a first claw 1195 and a first rotating shaft 144 are provided between the button 11 and the housing 14. One of the first claw 1195 and the first rotating shaft 144 is located on the button 11, and the other is located on the housing 14. The first claw 1195 engages with the first rotating shaft 144 and is in clearance fit with the first rotating shaft 144, allowing the first claw 1195 and the first rotating shaft 144 to rotate relative to each other, thereby enabling the button 11 to pivot based on the first rotating shaft 144. In a preferred embodiment, two first claws 1195 are arranged side by side facing the housing 14 at the middle position of the button 11, and the housing 14 integrally forms a protruding first rotating shaft 144 at the corresponding position of the first claws 1195. The first claw 1195 includes two opposing and non-contacting first claw arms 11951, which are integrally formed on the button 11. The two first claw arms 11951 interlock to form a circular first engagement hole 11952 between them. The diameter of the first engagement hole 11952 is larger than the diameter of the first rotating shaft 144, allowing for a clearance fit between the first engagement hole 11952 and the first rotating shaft 144. The two first claw arms 11951 have engagement openings facing the first rotating shaft 144. When installing the button 11, the engagement openings are pressed against the first rotating shaft 144 from top to bottom. The first claw arms 11951 separate under their own elastic force, allowing the first rotating shaft 144 to engage with the first engagement hole 11952. The first rotating shaft 144 can rotate within the first engagement hole 11952 to achieve a pivotal connection between the button 11 and the housing 14.

[0202] Furthermore, such as Figure 42 and Figure 43As shown, the reset part 15 is configured as at least one first elastic arm 154 extending from the housing 14. The first elastic arm 154 abuts against at least a portion of the button 11, providing the reset force to the button 11. The first elastic arm 154 abutting against the lower surface of the button 11 can be understood as the first elastic arm 154 extending from the housing 14 toward the button 11 in a bent manner, i.e., the first elastic arm 154 is tilted upwards to a certain height, and the upper surface of the end of the first elastic arm 154 abuts against the lower surface of the button 11. In a preferred embodiment, the middle part of the button 11 is pivotally connected to the housing 14. Both ends of the button 11 can be pressed to generate pivoting movement and trigger the corresponding detection element 12. The housing 14 is provided with two first elastic arms 154 at each end of the button 11. The two first elastic arms 154 located at the same end extend toward both sides of the button 11 and abut against the lower surface of the button 11. The four first elastic arms 154 corresponding to the button 11 abut against the lower surface of the button 11 and are tilted upwards at the same height, so that the button 11 is supported to a horizontal state and the magnitude of the reset force on both ends of the button 11 is the same. Further, a cylindrical pressing boss 1199 is provided on the lower surface of the button 11 at the end of the first elastic arm 154. The button 11 presses against the first elastic arm 154 through the cylindrical pressing boss 1199 to prevent the first elastic arm 154 from bending too high and reducing its strength. The cylindrical pressing boss 1199 compensates for part of the height so that the tilting height of the first elastic arm 154 is not too high.

[0203] Furthermore, the edge of the button 11 is provided with a first hook (not shown in the figure) for hooking onto the housing 14 to limit the extreme position of the upward movement of the button 11. The first hook on the edge of the button 11 can be understood as the first hook protruding from both ends of the button 11 that undergo pivoting movement towards the side wall of the housing 14, with a limiting step provided on the side wall of the housing 14 at the corresponding position of the first hook. The first hook hooking onto the housing 14 means that when the button 11 is not pressed, the first hook hooks onto the edge of the limiting step to limit the extreme position of the button 11's upward bounce. Its function is that, due to manufacturing errors in the first elastic arm 154, the elastic force and upward tilting height of the four first elastic arms 154 corresponding to the same button 11 differ, causing the upper surface of the button 11 to tilt, and the upper surfaces of each button 11 are not on the same plane, affecting aesthetics; therefore, in this embodiment, a first hook is provided at the end of the button 11 to limit the extreme position of the button 11's upward bounce and ensure that the upper surface of the button 11 is horizontal.

[0204] Furthermore, the first elastic arm 154 is tilted upwards towards the button 11 by a preset height, and the length of the first latch matches the preset height, so that when the button 11 is not displaced, the first elastic arm 154 is in a state of being pressed against by the button 11. The matching of the length of the first latch to the preset height can be understood as the first elastic arm 154 being positioned between the button 11 and the housing 14, and the length of the button latch 112 determining the distance between the button 11 and the housing 14. By controlling the length of the button latch 112, the distance between the button 11 and the housing 14 is made smaller than the preset height of the first elastic arm 154, so that even when the button 11 is not pressed, the first elastic arm 154 is also in a state of being pressed and deformed. Furthermore, the part of button 11 that protrudes towards the end of the first elastic arm 154 has an abutting protrusion, which is used to raise button 11 to a certain height, so that button 11 has sufficient pressing margin, and at the same time further presses against the first elastic arm 154 to deform it, so that when button 11 is not pressed, the first elastic arm 154 is also in a state of being pressed and deformed. The beneficial effect is that the first elastic arm 154 has a pre-tightening force on button 11, so that button 11 is still supported by the first elastic arm 154 when it is not pressed, ensuring that button 11 is in the upper limit position when not pressed, improving the flatness of the upper surface of each button 11, and improving the tightness of button 11, so that it will not be loose.

[0205] In another embodiment, the first elastic arm 154 is at least partially disposed between the button 11 and the detection element 12 (not shown in the figure). The button 11 presses against and triggers the detection element 12 through the first elastic arm 154. The first elastic arm 154 being at least partially disposed between the button 11 and the detection element 12 can be understood as the first elastic arm 154 extending from the housing 14, with its end positioned above the detection element 12. The upper surface of the end of the first elastic arm 154 abuts against the lower surface of the button 11. The button 11 indirectly triggers the detection element 12 by pressing against the end of the first elastic arm 154, while the first elastic arm 154 provides a reset force for the button 11. Furthermore, the end of the first elastic arm 154 has an arc-shaped protrusion facing the button 11, which is used to abut against the lower surface of the button 11. The advantage of using an arc-shaped protrusion is that the contact between the arc-shaped protrusion and the button 11 is a point contact, and the contact point is close to the center of the arc-shaped protrusion. Compared with surface contact, the contact position of point contact is easier to control. Correspondingly, the position of the arc-shaped protrusion abutting against the button 11 is relatively constant and will not change much during the pressing process, so that the button 11 can vertically press against the detection element 12 through the first elastic arm 154. The advantage of this embodiment, where the first elastic arm 154 presses against and triggers the detection element 12, is that the first elastic arm 154 is integrally formed with the housing 14, ensuring the relative positional accuracy between the first elastic arm 154 and the housing 14. Since the detection element 12 is mounted on the housing 14, the positioning accuracy between the first elastic arm 154 and the detection element 12 is guaranteed. Compared to the contact part 113 being located on the button 11, this embodiment uses the first elastic arm 154 to directly trigger the detection element 12, avoiding the accumulation of error dimensional chains between the contact part 113 and the detection element 12, making it easier to ensure the positioning accuracy between the first elastic arm 154 and the detection element 12, thereby reducing manufacturing precision requirements. Furthermore, no positioning relationship is needed between the button 11 and the detection element 12, reducing the positioning accuracy requirement of the button 11. No positioning structure is needed between the button 11 and the elastic limiting member 151, further reducing the manufacturing cost of the button 11 and the elastic limiting member 151.

[0206] In some embodiments, such as Figure 44 and Figure 45As shown, the button 11 includes a button body 1196 and a connecting part 1197. The button 11 is fixed to the housing 14 through the connecting part 1197. The button body 1196 can elastically deform in response to the operating force and generate the reset force to overcome the deformation, thereby forming the reset part 15. The button body 1196 is provided with a contact part 113 facing the detection element 12. When the operating force is applied to the button 11, the button body 1196 elastically deforms, causing the contact part 113 to directly or indirectly press against and trigger the detection element 12. When the operating force is removed, the deformation of the button body 1196 is restored, causing the contact part 113 to return to its original position. The reset part 15 formed by the button body 1196 can be understood as follows: the button 11 is configured as an elastic sheet structure capable of elastic deformation and generating the reset force. One end of the button 11 is fixedly connected to the housing 14, and the other end can be pressed to cause the button body 1196 to elastically deform; or, the middle part of the button 11 is fixedly connected to the housing 14, and both ends of the button 11 can be pressed to cause the button body 1196 to elastically deform; the button body 1196 is the reset part 15. The contact part 113 provided on the button body 1196 facing the detection element 12 can be understood as follows: when the button body 1196 is pressed and undergoes elastic deformation, its end displaces downward, and the contact part 113 extends integrally from the button body 1196 towards the housing 14, with the contact part 113 positioned above the detection element 12; when the end of the button 11 moves downward, it drives the contact part 113 to press downward and trigger the detection element 12.

[0207] In this embodiment, the reset force is provided by the elastic deformation of the button body 1196. The reset force is influenced by a single factor, making it easy to control through structural design. By changing the thickness and material of the button body 1196 and through calculation and simulation, the applicant controls the reset force to cooperate with the elastic force of the detection element 12, so that when the button 11 moves to the first pressing position, the reaction force is F1, and when the button 11 moves from the first pressing position to the second pressing position, the reaction force jumps from F1 to F2; where F2 < F1 < 400g; and the displacement S1 of the button 11 at the first pressing position and the displacement S2 at the second pressing position satisfy the relationship: S2 - S1 ≤ 2mm.

[0208] Furthermore, the connecting part 1197 is fixedly connected to the housing 14 by means of bolts, riveting, or snap-fit. The bolt connection means that the housing 14 has bolt holes, and the connecting part 1197 is tightened and fixed to the bolt holes of the housing 14 by bolts. The riveting means that the connecting part 1197 is fixed to the housing 14 by rivets.

[0209] Furthermore, such as Figure 44 As shown, the connecting portion 1197 is located at the middle position of the button 11. The housing 14 has abutment portions 113 at both ends of the button 11. Both ends of the button 11 can be displaced in response to the operating force, thereby driving the abutment portions 113 to trigger the detection element 12. Detection elements 12 are respectively located below the abutment portions 113 at both ends of the button 11. The middle position of the button 11 is fixedly connected to the housing 14 via the connecting portion 1197, and the abutment portions 113 extend downwards from both ends to trigger the detection elements 12 below. The operating force can be applied to both ends of the button 11, causing the button 11 to undergo elastic deformation. Under the action of the operating force, the two ends of the button 11 displace, driving the abutment portions 113 to trigger the detection elements 12.

[0210] In another embodiment, the connecting portion 1197 is disposed at one end of the button 11 (not shown in the figure), and the housing 14 is provided with the abutting portion 113 at the other end of the button 11 away from the first end. The other end of the button 11 can be displaced in response to the operating force, thereby driving the abutting portion 113 to trigger the detection element 12. Specifically, one end of the button 11 is fixedly connected to the housing 14 via the connecting portion 1197, and the other end of the button 11 extends downwards with the abutting portion 113 to trigger the detection element 12 below. The operating force acts on the other end of the button 11, causing the button 11 to undergo elastic deformation. Under the action of the operating force, the other end of the button 11 is displaced, driving the abutting portion 113 to trigger the detection element 12.

[0211] In a preferred embodiment, such as Figure 44 and Figure 45As shown, the connecting part 1197 is snapped onto the housing 14; the connecting part 1197 is provided with a first snap-fit ​​part 11971 facing the housing 14, and the housing 14 is provided with a second snap-fit ​​part 145 at a corresponding position of the first snap-fit ​​part 11971. The shape and size of the second snap-fit ​​part 145 are adapted to the first snap-fit ​​part 11971, so that the first snap-fit ​​part 11971 is snapped onto the second snap-fit ​​part 145, thereby realizing the fixed connection between the connecting part 1197 and the housing 14. Furthermore, the first latching portion 11971 includes at least one second latching claw 11972, and the second latching portion 145 includes at least one latching shaft 1451. The second latching claw 11972 latches onto the latching shaft 1451 and is in an interference fit with the latching shaft 1451. The interference fit is such that the second latching claw 11972 and the latching shaft 1451 cannot rotate relative to each other within the preset deformation range of the button 11, so as to achieve a fixed connection between the second latching claw 11972 and the latching shaft 1451. The preset deformation range of the button 11 refers to the deformation range of the button 11 within its pressing stroke. In one specific embodiment, each button 11 has two corresponding second claws 11972, which are arranged side by side and spaced apart on the lower surface of the button 11. The second claw 11972 includes two opposing and non-contacting second claw arms 11973. The second claw arms 11973 are integrally formed on the button 11. The two second claw arms 11973 hug each other to form a circular second locking hole 11974 between the two second claw arms 11973. The diameter of the second locking hole 11974 is smaller than the shaft diameter of the locking shaft 1451, so that the second locking hole 11974 and the locking shaft 1451 are interference fit. Two second claw arms 11973 have guide openings facing the locking shaft 1451. When installing the button 11, the guide openings are pressed against the locking shaft 1451 from top to bottom. The second claw arms 11973 separate from each other under their own elastic force, so that the locking shaft 1451 is locked into the second locking hole 11974, thereby realizing the fixed connection between the connecting part 1197 and the housing 14.

[0212] Furthermore, such as Figure 44 and Figure 45As shown, the housing 14 is provided with a second elastic arm 155, which abuts against the button 11 to assist the button 11 in resetting. The second elastic arm 155 abutting against the lower surface of the button 11 can be understood as the second elastic arm 155 extending from the housing 14 toward the button 11 in a bent manner, i.e., the second elastic arm 155 is tilted upwards to a certain height, and the upper surface of the end of the second elastic arm 155 abuts against the lower surface of the button 11. The second elastic arm 155 assists in the reset of the button 11. This can be understood as follows: Since the button 11 is fixedly connected to the housing 14, pressing the button 11 causes elastic deformation and generates a reset force. Simultaneously, the second elastic arm 155 also exerts a reset force on the button 11. The purpose of this reset force is to prevent the button 11 from losing its original elasticity after prolonged use, thus preventing it from returning to its initial state. Frequently used buttons 11 may collapse downwards and fail to spring back, preventing the detection element 12 from returning to its non-triggered state and affecting normal use. Furthermore, infrequently used buttons 11 may rebound normally, leading to uneven surfaces on the upper surface of the button 11 after prolonged use. Therefore, the second elastic arm 155 is provided to assist the button 11 in returning to its initial position.

[0213] Furthermore, such as Figure 44 As shown, each button 11 has at least one second hook 1198 facing the housing 14. The second hook 1198 can hook onto the housing 14, ensuring that the upper surface height of each button 11 is consistent. The upper surface of each button 11 is set as the surface of the button 11 facing away from the housing 14. The ability of the second hook 1198 to hook onto the housing 14 can be understood as the housing 14 having a hook-through hole 146 at the corresponding position of the second hook 1198. When the button 11 is not pressed, the second hook 1198 extends into the hook-through hole 146 and hooks the lower edge of the hook-through hole 146, thus limiting the maximum upward movement of the button 11. In a preferred embodiment, each button 11 has four second hooks 1198, located at the four corners of the button 11, symmetrically providing a limiting force for the button 11. Its function is to address the issue that, due to manufacturing errors in the second elastic arms 155, the elastic force and upward tilting height of multiple second elastic arms 155 corresponding to the same button 11 vary, causing the upper surface of the button 11 to tilt and the upper surfaces of each button 11 to be not on the same plane, affecting aesthetics. Therefore, the second hook 1198 limits the upward tilting height of the button 11, ensuring that the upper surface of each button 11 is horizontal. In another preferred embodiment, the second hook 1198 is located at the end of the button 11 (not shown in the figure) to limit the extreme position of the upward tilting of the end of the button 11, thereby more accurately ensuring that the upper surface of each button 11 is horizontal.

[0214] Furthermore, such as Figure 11As shown, the housing 14 includes an upper housing 141 and a lower housing 142. The upper housing 141 covers the lower housing 142 and is detachably connected to the lower housing 142. The upper housing 141 covering the lower housing 142 can be understood as having a recessed receiving groove facing the lower housing 142, capable of accommodating at least a portion of the lower housing 142. When the upper housing 141 is fastened to the lower housing 142, at least a portion of the lower housing 142 is accommodated within the receiving groove. In one specific embodiment, four receiving groove sidewalls extend from the side of the upper housing 141 towards the lower housing 142, and the four receiving groove sidewalls surround each other to form the receiving groove. The detachable connection to the lower housing 142 includes magnetic, bolt, or snap-fit ​​connections.

[0215] Furthermore, such as Figure 3 , Figure 11 and Figure 16As shown, the button 11 is movably connected to the upper housing 141, allowing the button 11 to move relative to the upper housing 141 and trigger the detection element 12 during the movement. The movable connection between the button 11 and the upper housing 141 can be understood as follows: The button 11 is movably connected to the housing 14 as described above, with a detailed connection structure. Here, the connection between the button 11 and the upper housing 141 is specifically defined as the same as the connection structure described above, and will not be repeated here. The smart switch also includes a power board 17, disposed on the lower housing 142, for connecting an external power cord; at least one PCB board 16, electrically connected to the power board 17, providing power to the PCB board 16 via the power board 17; wherein the detection element 12 is disposed on the PCB board 16 and electrically connected to the PCB board 16. The power board 17 being disposed on the lower housing 142 can be understood as the power board 17 being fixedly connected to the lower housing 142 by bolts, snap-fit, clamping, or other feasible connection methods. The power board 17 is used to connect to an external power supply, meaning it is connected to an external 220V AC power source. The power board 17 also has electronic components that convert the 220V AC power to DC power to supply other DC electronic components. The PCB board 16 is electrically connected to the power board 17, meaning it can be electrically connected via metal contacts, wires, pin headers 161, or pin headers 173. The detection element 12 is disposed on and electrically connected to the PCB board 16, meaning it is soldered to the PCB board 16, snapped onto the PCB board 16, and abuts against the PCB board 16 via metal contacts or conductive springs. In a preferred embodiment, the PCB board 16 is fixedly mounted on the lower housing 142. In daily use of switches, when there are too many switch buttons 11, users easily forget the correspondence between buttons 11 and lights. With the introduction of smart switches, the switch may represent not only a single light but also many scene modes, such as "away mode" and "all-on mode," making the functions represented by the switch more complex and harder for users to remember. Based on this, existing technologies offer a certain degree of customer-customized laser engraving technology, allowing users to choose to laser engrave the text or icons they need on the switch. However, this solution makes it difficult to modify the display content of the buttons 11 later. Therefore, this invention detachably connects the upper housing 141 and the lower housing 142. When a button 11 is damaged or its display content needs to be changed, it is not necessary to replace the entire switch; only the upper housing 141 and the button 11 need to be replaced. Furthermore, the button 11 and the upper housing 141 can be combined into a button 11 module for complete replacement.The PCB board 16 and power board 17 are disposed in the lower housing 142. Correspondingly, the electronic components of the switch connected to the PCB board 16 and power board 17 are also disposed in the lower housing 142. The upper housing 141 is only provided with button 11. When the upper housing 141 is replaced, the circuit part will not be involved, which can reduce the cost of replacing the upper housing 141.

[0216] Furthermore, such as Figure 8 and Figure 11 As shown, the upper housing 141 and the lower housing 142 are connected by magnetic attraction. The upper housing 141 is provided with at least one magnet 1416, and the lower housing 142 is provided with at least one magnetic attractant 1422, which can be attracted by the magnet 1416. The upper housing 141 is attracted to the magnetic attractant 1422 by the magnet 1416, thereby achieving a detachable connection between the upper housing 141 and the lower housing 142. The provision of at least one magnet 1416 in the upper housing 141 can be understood as the upper housing 141 being fixedly connected to a magnet 1416, and the fixing method includes adhesive, snap-fit, bolt connection, or clamping. The provision of at least one magnetic attractant 1422 in the lower housing 142 can be understood as the lower housing 142 being fixedly connected to at least one magnetic attractant 1422, and the connection method includes snap-fit, adhesive, bolt connection, etc. The magnetic attractor 1422 is made of ferrous material so that it can attract the magnet 1416. Furthermore, the magnetic attractor 1422 is a sheet metal part 14221, which can be fixedly installed on a mounting surface to fix the lower housing 142 to the mounting surface. The mounting surface can be understood as a wall. In a specific embodiment, the sheet metal part 14221 has at least one screw hole 14222, the diameter of which is adapted to a screw, allowing the screw to pass through and fix the sheet metal part 14221 to the mounting surface. The screw fixing the sheet metal part 14221 to the mounting surface can be understood as follows: the diameter of the screw nut 17221 is larger than the diameter of the screw hole 14222; the screw shank 17222 passes through the screw hole 14222 and is tightened to fix it to the mounting surface, pressing the sheet metal part 14221 against the mounting surface. The beneficial effect of using sheet metal part 14221 for magnetic component 14222 is that sheet metal part 14221 is generally available in wall switches. Wall switches need to be installed on the wall through sheet metal part 14221. In this invention, sheet metal part 14221 is also used as magnetic component 1422, so that the lower housing 142 does not need to be provided with a separate magnetic component 1422 to complete the magnetic connection with the upper housing 141, which simplifies the structure and saves costs.

[0217] The upper housing 141 and the lower housing 142 are magnetically connected, which makes it easy to disassemble and replace the upper housing 141. When the surface of the button 11 is worn or damaged, or when the pattern or text on the surface of the button 11 needs to be replaced, the upper housing 141 and the button 11 can be quickly replaced as a whole to obtain a brand new switch panel with changed display content.

[0218] Furthermore, such as Figure 13 and Figure 14As shown, sheet metal part 14221 is snapped into lower housing 142. In one specific embodiment, a through hole matching the shape of the lower housing 142 is formed in the center of sheet metal part 14221. Sheet metal part 14221 is inserted from below the lower housing 142 and snapped into the outer surface of the lower housing 142. The through hole in the center of sheet metal part 14221 matching the shape of the lower housing 142 can be understood as the through hole in the center of sheet metal part 14221 fitting against the outer wall of the lower housing 142, so that the through hole of sheet metal part 14221 snaps into the outer wall of the lower housing 142. In one specific embodiment, the outer surface of the lower housing 142 includes at least a first outer side wall 14231, a second outer side wall 14232, a third outer side wall 14233, and a fourth outer side wall 14234 that surround each other, wherein the first outer side wall 14231 and the second outer side wall 14232 are disposed opposite to each other, and the third outer side wall 14233 and the fourth outer side wall 14234 are disposed opposite to each other. The first outer wall 14231 and the second outer wall 14232 are each provided with two sheet metal fasteners 14235. The first outer wall 14231 is provided with a first abutment 14236 between the two sheet metal fasteners 14235. The second outer wall 14232 is provided with a second abutment 14237 between the two sheet metal fasteners. The third outer wall 14233 is provided with two third abutments 14238. The fourth outer wall 14234 is provided with two fourth abutments 14239. The first abutment 14236, the second abutment 14237, the third abutment 14238 and the fourth abutment 14239 are at the same horizontal height. When the sheet metal part 14221 is inserted from below the lower housing 142, the upper surface of the sheet metal part 14221 abuts against the first abutting part 14236, the second abutting part 14237, the third abutting part 14238, and the fourth abutting part 14239 to restrict the upward displacement of the sheet metal part 14221. At the same time, the lower surface of the sheet metal part 14221 is respectively engaged with the sheet metal part buckle 14235 to restrict the downward displacement of the sheet metal part 14221. The first abutting part 14236, the second abutting part 14237, the third abutting part 14238, and the fourth abutting part 14239 cooperate with the horizontal height of the sheet metal part buckle 14235, so that the sheet metal part 14221 is locked into the lower housing 142. The aforementioned horizontal height coordination can be understood as follows: in the vertical direction, the distance between the first abutment 14236, the second abutment 14237, the third abutment 14238, and the fourth abutment 14239 and the sheet metal fastener 14235 is equal to the thickness of the sheet metal 14221, so that the sheet metal 14221 can be clamped and fixed.

[0219] Furthermore, such as Figure 8 , Figure 11 and Figure 12 As shown, the upper housing 141 has at least one magnet mounting groove 14161 on the side facing the button 11. The shape of the magnet mounting groove 14161 is adapted to the magnet 1416. The side wall of the magnet mounting groove 14161 is provided with a magnet limiting rib. The lower surface of the magnet 1416 is at least partially attached to the bottom wall of the magnet mounting groove 14161. The magnet limiting rib clamps the side surface of the magnet 1416 to limit the magnet 1416. The shape of the magnet mounting groove 14161 adapted to the magnet 1416 can be understood as follows: the magnet mounting groove 14161 is slightly larger than the magnet 1416, and the magnet mounting groove 14161 is open towards the button 11. The depth of the magnet mounting groove 14161 is greater than or equal to the height of the magnet 1416, so that after the magnet 1416 is inserted from the magnet mounting groove 14161 towards the button 11, the upper surface of the magnet 1416 is flush with or lower than the upper surface of the upper housing 141. The lower surface of the magnet 1416 is at least partially in contact with the bottom wall of the magnet mounting groove 14161 (e.g., Figure 21As shown, the bottom surface of the magnet mounting groove 14161 facing the magnetic suction member 1422 is at least partially attached to the magnetic suction member 1422 to reduce the distance between the magnet 1416 and the magnetic suction member 1422, thereby increasing the magnetic attraction between the magnet 1416 and the magnetic suction member 1422, and further increasing the magnetic attraction between the upper housing 141 and the lower housing 142, preventing the upper housing 141 from falling off. The magnet limiting ribs clamping the side surface of the magnet 1416 to limit the magnet 1416 can be understood as the distance between each magnet limiting rib matching the width of the magnet 1416, so that when the magnet 1416 is placed in the magnet mounting groove 14161, the magnet limiting ribs and the magnet 1416 have an interference or transition fit, so that the magnet mounting groove 14161 clamps the magnet 1416 in the middle to prevent the magnet 1416 from shaking in the magnet mounting groove 14161. The function of the magnet limiting rib is as follows: First, without the magnet limiting rib, if the magnet 1416 is clamped only by the side wall of the magnet mounting groove 14161, manufacturing errors may cause the magnet mounting groove 14161 to be too small, making it impossible to insert the magnet 14166, or the magnet mounting groove 14161 to be too large, making it impossible to clamp the magnet 14166, causing the magnet 14166 to wobble within the magnet mounting groove 14161. In this embodiment, the magnet limiting rib is used to clamp the magnet 1416, effectively avoiding the impact of manufacturing errors. During the dimensional design, the magnet limiting rib and the magnet 1416 are interference-fitted, and the interference is compensated by the deformation of the magnet limiting rib, thereby eliminating the impact of manufacturing errors. Furthermore, the magnet limiting rib has a guide slope at the entrance of the magnet mounting groove 14161 to help insert the magnet 1416 and prevent the magnet 1416 from being unable to be inserted due to excessive interference from the magnet limiting rib. The second function of the magnet limiting rib is to ensure that the lower surface of the magnet 1416 adheres to the bottom wall of the magnet mounting groove 14161. This is because without the magnet limiting rib, if the magnet 1416 is clamped by the side wall of the magnet mounting groove 14161, there will be a rounded corner between the side wall and the bottom wall. If this rounded corner is larger than the rounded corner of the magnet 1416, the lower surface of the magnet 1416 will not be able to adhere to the bottom wall of the magnet mounting groove 14161, weakening the attraction of the magnet 1416 to the magnetic attractor 1422. In this embodiment, the magnet limiting rib pushes the magnet 1416 away from the side wall of the magnet mounting groove 14161, ensuring that the rounded corner of the magnet mounting groove 14161 has no effect on the magnet 1416, and allowing the lower surface of the magnet 1416 to adhere to the bottom wall of the magnet mounting groove 14161.

[0220] Furthermore, such as Figure 8As shown, the magnet 1416 is rectangular in shape, and there are four magnets 1416, arranged in pairs at both ends of the upper housing 141. Two magnets 1416 at the same end are connected end-to-end, arranged in a line-like pattern. In one specific embodiment, the magnet 1416 is a long rectangular prism, and correspondingly, the magnet mounting groove 14161 is a long rectangular prism groove. In other embodiments, the magnet 1416 can be a cube or other shapes. Because the magnets 1416 are located at both ends of the upper housing 141, due to the lever principle, during the pressing of the button 11, the magnetic attraction of the magnets 1416 holds the upper housing 141 at both ends, making it less likely for the upper housing 141 to tilt or detach during the pressing process. Since the two magnets 1416 located at the same end are connected end to end and arranged in a similar "I" shape, the two magnets 1416 can cover the length of the upper shell 141 in the direction of magnet 1416 distribution as much as possible, thereby increasing the magnetic attraction between the magnets 1416 and the magnetic attractor 1422.

[0221] Furthermore, such as Figure 11 As shown, the outer side wall of the lower housing 142 is provided with a first positioning part 1424, and the inner side wall of the upper housing 141 is provided with a second positioning part 1418. When the upper housing 141 covers the lower housing 142, the second positioning part 1418 is sleeved on the first positioning part 1424, and the inner surface of the second positioning part 1418 at least partially abuts against the outer surface of the first positioning part 1424, so that the upper housing 141 is positioned by the lower housing 142 in the horizontal direction. In a specific embodiment, as shown... Figure 11 As shown, the inner sidewall of the upper housing 141 includes two first inner sidewalls with magnet mounting grooves 14161, and two second inner sidewalls adjacent to the two first inner sidewalls. Each of the two second inner sidewalls has a square protrusion 14181, which, together with the magnet mounting grooves 14161, forms the second positioning portion 1418. The lower housing 142 has positioning ribs 14241 protruding outwards from the first outer sidewall 14231 and the second outer sidewall 14232, respectively. The positioning ribs 14241, together with the third abutment portion 14238 and the fourth abutment portion 14239, form the first positioning portion 1424.

[0222] Furthermore, such as Figure 11 As shown, the first positioning part 1424 is provided with a guide part 14242 facing the second positioning part 1418. The guide part 14242 is configured as an inclined surface so that the second positioning part 1418 can be fitted into the first positioning part 1424.

[0223] Furthermore, such as Figure 11As shown, the magnetic member 1422 is at least partially enclosed within the upper housing 141, and the lower surface of the magnetic member 1422 is flush with or protrudes from the lower end face of the upper housing 141. In one specific embodiment, the distance between the surface of the magnet mounting groove 14161 facing the magnetic member 1422 and the lower end face of the upper housing 141 is less than or equal to the thickness of the magnetic member 1422, such that the lower surface of the magnetic member 1422 is flush with or protrudes from the lower end face of the upper housing 141. The beneficial effect is that, since the magnetic member 1422 is a sheet metal part 14221, when the sheet metal part 14221 is tightened to the wall, the upper housing 141 will not abut against the wall surface, causing the surface of the magnet mounting groove 14161 facing the sheet metal part 14221 to not fit against the sheet metal part 14221, resulting in a reduction in magnetic attraction.

[0224] like Figure 16 and Figure 15 As shown, the specific connection structure of the power board 17 in the lower housing 142 is as follows: the inner wall of the lower housing 142 is provided with a power board limiting rib 1425, which is used to abut against the side of the power board 17 to pre-position the power board 17; the lower housing 142 is provided with a power board positioning post 1429 from bottom to top; the power board 17 is provided with a power board positioning hole 174 at the corresponding position of the power board positioning post 1429; the power board positioning post 1429 is inserted into the power board positioning hole 174 of the power board 17 to position the power board 17 in the horizontal direction; the lower housing 142 is provided with a power board mounting part; the power board mounting part is provided with a power board bolt hole 14291; the power board 17 is placed in the power board mounting part to be supported by the power board mounting part and is fastened to the power board bolt hole 14291 by the power board 17 bolts.

[0225] Furthermore, such as Figure 29 As shown, the power board 17 has at least three terminals 171 facing the bottom of the lower housing 142 for connecting the external power cord and the controlled devices. The terminals 171 are electrically connected to the power board 17; specifically, the terminals 171 are soldered to the power board 17. Each terminal 171 is a metal conductive post extending from the power board 17 towards the bottom of the lower housing 142, used to connect the live wire, neutral wire, and the controlled electrical appliance. In this embodiment, the power board 17 has six terminals 171 soldered on. Two terminals 171 connect the neutral wire and the live wire, and the other four terminals 171 are electrically connected to the live wire interfaces of four controlled devices. The four terminals 171 connected to the controlled devices are electrically connected to the power board 17 via relays 175. The power board 17 can control the power on and off of the four controlled devices via the relays 175, which are soldered to the power board 17.

[0226] Furthermore, such as Figure 17 As shown, the lower housing 142 has multiple strip-shaped heat dissipation holes 1427 vertically arranged on its side surface. These holes are arranged side-by-side horizontally, extending upwards from the bottom of the lower housing 142 with a height less than 13mm. Because the power board 17 is equipped with an AC / DC conversion module 176 (such as...), Figure 29 As shown, the power board 17 includes relays 175 and other electronic components. Its functions include at least converting 220V AC to DC via the AC-DC conversion module 176 and controlling the power supply to and from various controlled devices via relays 175. Since the controlled devices' power comes from the power board 17, it generates considerable heat. To prevent overheating and damage to the circuitry, heat dissipation holes 1427 are provided on the side surface of the lower housing 142 from bottom to top. The positions of the heat dissipation holes 1427 correspond to the electronic components on the power board 17, aiding in heat dissipation. Furthermore, the upward extension height of the heat dissipation holes 1427 is less than 13mm to prevent users from seeing the internal electronic components through the holes, thus avoiding aesthetic concerns.

[0227] Furthermore, such as Figure 16 As shown, a wiring module 172 is placed at a corresponding position at the end of the terminal 171 in the lower housing 142. The wiring module 172 includes a wiring sleeve 1721 and a wiring bolt 1722. The wiring sleeve 1721 is sleeved on the terminal 171. The side wall of the wiring sleeve 1721 has a threaded hole adapted to the wiring bolt 1722. The wiring bolt 1722 can be screwed into the threaded hole and presses the terminal 171 against the inner wall of the wiring sleeve 1721. The connection bolt 1722 pressing the terminal 171 against the inner wall of the terminal sleeve 1721 can be understood as follows: the wire passes through the terminal sleeve 1721 and is placed between the terminal 171 and the inner wall of the terminal sleeve 1721. The connection bolt 1722 presses the terminal 171 against the inner wall of the terminal sleeve 1721, so that the terminal 171 and the terminal sleeve 1721 clamp and fix the wire, and the terminal 171 and the wire are in contact and conductive. It is worth noting that the width of the terminal sleeve 1721 in the axial direction of the connection bolt 1722 is at least three times the width of the terminal 171, so that there is a gap between the terminal sleeve 1721 and the terminal 171 to allow the wire to pass through. The terminal 171 has an arc-shaped plate structure. The side of the terminal sleeve 1721 that abuts against the terminal 171 is arc-shaped to fit the shape of the terminal 171, so that the terminal 171 and the terminal sleeve 1721 clamp the wire more tightly. At the same time, the side of the terminal 171 that abuts against the terminal sleeve 1721 is processed with horizontal stripes, so that the terminal 171 presses against the wire more firmly and prevents the wire from falling off.

[0228] Furthermore, such as Figure 16 and Figure 17 As shown, the wiring bolt 1722 includes an integrally formed nut 17221 and a screw 17222. Multiple first wiring through holes 14261 are formed on the side surface of the lower housing 142 at corresponding positions on the wiring module 172. The diameter of the first wiring through holes 14261 is larger than the diameter of the nut 17221, allowing the nut 17221 to be inserted into the first wiring through hole 14261 from inside the lower housing 142, with at least a portion exposed outside the lower housing 142. The phrase "at least a portion exposed outside the lower housing 142" can be understood as the end of the nut 17221 of the wiring bolt 1722, away from the screw 17222, being exposed outside the lower housing 142. The end of the nut 17221 is provided with a cross-shaped or flat-head screwdriver for easy tightening. The bottom surface of the lower housing 142 has multiple second wiring through holes 14262 at corresponding positions of the terminal 171. The wire is inserted through the second wiring through hole 14262 and passes through at least between the terminal 171 and the wiring sleeve 1721. When the wiring bolt 1722 is screwed toward the inside of the wiring sleeve 1721 until it abuts against the terminal 171, the continued screwing of the wiring bolt 1722 will cause the wiring sleeve 1721 to move to the left. The wire is clamped between the terminal 171 and the inner wall of the wiring sleeve 1721, so that the wire and the terminal 171 are pressed together to achieve conductivity.

[0229] Furthermore, such as Figure 17 and Figure 15 As shown, a stop portion 17223 is provided between the nut 17221 and the screw 17222. The stop portion 17223 is a ring-shaped structure arranged around the nut 17221. The outer diameter of the stop portion 17223 is larger than the diameter of the nut 17221 and the diameter of the first wiring through hole 14261, so that the stop portion 17223 cannot pass through the first wiring through hole 14261. The inner wall of the lower housing 142 with the first wiring through hole 14261 is designated as the first inner wall. The wire bolt 1722 is inserted downward from above the lower housing 142, and the nut 17221 is inserted into the first wiring through hole 14261. The first wiring through hole 14261 restricts the vertical displacement of the wire bolt 1722. The end of the screw 17222 away from the nut 17221 is abutted by the terminal post 171. The terminal post 171 and the first inner wall clamp the stop part 17223 and the screw 17222 in the middle to restrict the horizontal displacement of the wire bolt 1722.

[0230] Specifically, the wiring bolt 1722 is inserted downward from above the lower housing 142, pressed against and pushed into the first wiring through hole 14261 by the wiring post 171. The first wiring through hole 14261 restricts the vertical displacement of the wiring bolt 1722. At the same time, the wiring post 171 and the inner wall of the lower housing 142 clamp the wiring bolt 1722 in the middle to restrict the horizontal displacement of the wiring bolt 1722. In one specific embodiment, the lower housing 142 is provided with a wiring module placement groove 14264, the shape of which is adapted to the wiring module 172 to limit the horizontal displacement of the wiring module 172 perpendicular to the axial direction of the wiring bolt 1722; the wiring module placement groove 14264 is provided with a bolt limiting rib 14265 from the upper part of the lower housing 142 toward the bottom of the lower housing 142, which restricts the nut 17221 of the wiring bolt 1722 between the bolt limiting rib 14265 and the inner wall of the lower housing 142, thereby restricting the movement of the wiring bolt 1722 toward the inner side of the lower housing 142; the side of the power board 17 is first pre-positioned against the power board limiting rib 1425, and is tilted downward into the lower housing 142, so that the wiring post 171 is tilted into the lower housing 142, and then turns to a vertical state. When the wiring post 171 changes from tilted to vertical, the wiring bolt 1722 is pressed by the wiring post 171 and pushed into the first wiring through hole 14261. The distance between the bolt limiting rib 14265 and the first inner wall of the lower housing 142 is greater than the height of the nut 17221 of the terminal 171 bolt, allowing the terminal 171 bolt to be inserted downwards into the terminal module placement slot 14264 from the upper part. The terminal bolt 1722 is inserted downwards from the upper part of the lower housing 142, pushing the nut 17221 into the first wiring through hole 14261, which restricts the vertical displacement of the terminal bolt 1722. When the power board 17 is installed on the lower housing 142, the end of the screw 17222 away from the nut 17221 is pressed against the terminal 171, so that the terminal 171 and the first inner wall clamp the stop part 17223 and the screw 17222 of the terminal bolt 1722 in the middle, thereby restricting the horizontal displacement of the terminal bolt 1722.

[0231] Furthermore, such as Figure 17 As shown, the distance between the portion of the terminal block 171 that abuts against the screw 17222 and the first inner wall is less than the total length of the wiring bolt 1722. This ensures that when the wiring module 172 is placed into the wiring module placement slot 14264 from above the lower housing 142, and the power board 17 is placed into the lower housing 142, the terminal block 171 presses against the tail end of the screw 17222 of the wiring bolt 1722, pushing the wiring bolt 1722 towards the first side wall. The nut 17221 is then pushed into the first wiring through hole 14261, thus limiting the wiring module 172 in the vertical direction and preventing it from moving up and down or tilting during transportation.

[0232] The distance between the bolt limiting rib 14265 and the first sidewall is greater than the sum of the thicknesses of the nut 17221 and the stop portion 17223 of the wiring bolt 1722, so that the wiring bolt 1722 can be inserted into the wiring module placement slot 14264 without interference. The first inner wall has a stop limiting part 14266 protruding at the corresponding position of the stop part 17223. The stop limiting part 14266 can limit the leftward displacement of the stop part 17223, so that the terminal bolt 1722 is restricted in the axial direction between the terminal post 171 and the stop limiting part, further restricting the displacement of the terminal bolt 1722 and preventing the terminal bolt 1722 from shaking. The height of the stop limiting part 14266 protruding from the first inner wall is less than the height of the nut 17221 of the terminal bolt 1722, so that the nut 17221 can partially extend into the first wiring through hole 14261. The distance between the terminal post 171 and the stop limiting part is greater than the sum of the length of the screw 17222 of the terminal bolt 1722 and the thickness of the stop part 17223, so that the terminal post 171 and the terminal bolt 1722 do not interfere with each other, and the terminal bolt 1722 will not bend the terminal post 171.

[0233] Furthermore, such as Figure 19 As shown, a header pin 161 and a header nut 173 that can cooperate with each other are provided between the PCB board 16 and the power board 17. One of the header pins 161 and the header nuts 173 is located on the PCB board 16, and the other is located on the power board 17. The header pin 161 is inserted into the header nut 173 to realize the electrical connection between the PCB board 16 and the power board 17. In a specific embodiment, the PCB board 16 is disposed above the power board 17, and the header pins 161 are soldered onto the PCB board 16 facing the power board 17. The power board 17 has header nuts 173 that can cooperate with the header pins 161 at corresponding positions. The header pins 161 are inserted into the header nuts 173 to realize the electrical connection between the PCB board 16 and the power board 17.

[0234] In addition, the PCB board 16 and the power board 17 can also be connected via metal contacts. Specifically, the PCB board 16 has multiple metal contacts (not shown in the figure) facing the power board 17. The power board 17 has conductive abutment posts at corresponding positions of the metal contacts. The abutment posts are electrically connected to the power board 17, and the metal contacts abut against the abutment posts to achieve electrical connection between the PCB board 16 and the power board 17. An elastic connector is provided between the abutment posts and the power board 17. The abutment posts compress the elastic connector in response to the pressure of the metal contacts. The elastic connector generates elastic deformation and a reaction force to overcome the elastic deformation, causing the abutment posts to generate compressive displacement and a rebound force in the opposite direction of the compressive displacement. The function of the elastic connector is that, due to the manufacturing errors and varying lengths of the multiple abutment posts, the elastic connector provides elasticity to the abutment posts, ensuring that all abutment posts abut against the metal contacts and guaranteeing good conductivity.

[0235] Furthermore, such as Figure 19 and Figure 20 As shown, the PCB board 16 is disposed on the lower housing 142; the two oppositely disposed sidewalls of the lower housing 142 are recessed inward to form two oppositely disposed U-shaped recesses 1428. The PCB board 16 has a U-shaped notch 162 passing through the U-shaped recesses 1428 at opposite positions. The position and shape of the U-shaped notch 162 match the U-shaped recesses 1428 to position the PCB board 16 in the horizontal direction. The matching of the position and shape of the U-shaped notch 162 with the U-shaped recesses 1428 can be understood as the width of the U-shaped notch 162 matching the width of the U-shaped recesses 1428, and the distance between the two U-shaped notches 162 matching the distance between the two U-shaped recesses 1428, so that the outer wall of the U-shaped notch 162 abuts against the inner wall of the U-shaped recesses 1428, and the PCB board 16 is limited by the lower housing 142 in the horizontal direction.

[0236] The lower housing 142 is provided with a PCB board 16 support portion for abutting against the lower surface of the PCB board 16 to support the PCB board 16; the upper end of the lower housing 142 is provided with an isolation cover 18, the isolation cover 18 extending downward to form a PCB board abutment portion 181 for abutting against the upper surface of the PCB board 16 to limit the PCB board 16 in the vertical direction. The PCB board 16 support portion can be understood as a support rib extending from the inner sidewall of the lower housing 142, and the PCB board abutment portion 181 is a pressure rib extending from the edge of the isolation cover 18 towards the lower housing 142. Additionally, as... Figure 13 As shown, the sheet metal part 14221 has screw holes 14222 at opposite positions of the two U-shaped recesses 1428 of the lower housing 142, so as to save space occupied by the screw holes 14222.

[0237] In some embodiments, such as Figure 46 As shown, a level 147 is provided on the side of the lower housing 142 facing the button 11 to indicate the levelness of the smart switch when it is installed on a mounting surface; the level 147 is configured as a cylindrical bubble level 147. In a specific embodiment, a level 147 latch is provided on the isolation cover 18, and the bubble level 147 is snapped and fixed to the isolation cover 18. When the user installs the switch on a mounting surface such as a wall, cabinet, or desktop, the user can see whether the switch is installed crookedly through the bubble level 147, which facilitates positioning and drilling in the wall.

[0238] In another embodiment, such as Figures 47-50 As shown, the upper housing 141 has a PCB board mounting shell 148 facing the lower housing 142. The upper housing 141 covers the PCB board mounting shell 148, forming a cavity with the PCB board mounting shell 148. The PCB board 16 is disposed inside the cavity and is fixedly connected to the PCB board mounting shell 148. The upper housing 141 covering the PCB board mounting shell 148 can be understood as the PCB board mounting shell 148 being a slot-shaped structure with a top opening, fixedly installed below the upper housing 141, with the upper housing 141 covering the top opening of the PCB board mounting shell 148. The PCB board 16 being disposed inside the cavity can be understood as the PCB board 16 being fixedly installed inside the slot-shaped structure of the PCB board mounting shell 148 and covered below the upper housing 141. The advantage of placing the PCB board 16 on the upper housing 141 is that it shortens the error dimension chain between the detection element 12 and the contact part 113, making it easier to control the positioning accuracy between the contact part 113 and the detection element 12. Specifically, since the button 11 is connected to the upper housing 141, and the PCB board 16 is fixedly connected to the upper housing 141 through the PCB board mounting shell 148, the positioning reference of the button 11 and the PCB board 16 is the upper housing 141, and the positioning accuracy between the two is high. Since the detection element 12 is soldered to the PCB board 16 and the contact part 113 protrudes from the button 11, the positioning error between the detection element 12 and the contact part 113 is very small, reducing the requirements for processing accuracy and thus reducing manufacturing costs. Compared to the previous embodiment where the PCB board 16 is fixedly mounted on the lower housing 142 and the button 11 is located on the upper housing 141, and the lower housing 142 is detachably connected to the upper housing 141, the positioning reference between the detection element 12 and the contact part 113 undergoes multiple conversions, resulting in dimensional chain accumulation. The cumulative errors of each dimension form a large error, requiring control of the machining accuracy of the parts to reduce the error, which increases manufacturing costs. However, mounting the PCB board 16 on the upper housing 141 avoids this problem, and simplifies the dimensional tolerance design.

[0239] Furthermore, such as Figure 48 As shown, the internal shape of the PCB mounting shell 148 matches the shape of the PCB board 16. The PCB mounting shell 148 is fitted onto the PCB board 16 and positions the PCB board 16 in the horizontal direction. The PCB board 16 is fixedly mounted to the PCB mounting shell 148 by screws. The matching of the internal shape of the PCB mounting shell 148 to the shape of the PCB board 16 can be understood as the inner wall of the PCB mounting shell 148 at least partially abutting against the side wall of the PCB board 16, thereby positioning the PCB board 16 in the horizontal direction. Wherein, as... Figure 49 and Figure 48 As shown, to allow the PCB mounting shell 148 to fit into the bottom shell 19, the shape of the PCB mounting shell 148 matches the inner wall shape of the bottom shell 19. Since bolt mounting holes are pre-drilled on both sides of the bottom shell 19, the two sides of the bottom shell 19 are recessed inwards. Consequently, the two sides of the PCB mounting shell 148 are also recessed inwards, and consequently, the two sides of the PCB board 16 are also recessed inwards. The PCB board 16 is fixed to the PCB mounting shell 148 by screws. This can be understood as the PCB mounting shell 148 having at least two threaded connecting posts protruding towards the PCB board 16, supporting the lower surface of the PCB board 16. The threaded connecting posts are threaded, and the PCB board 16 is tightened and fixed to the threaded connecting posts by screws. In this embodiment, the PCB board 16 is fixed to the threaded connecting posts by three screws.

[0240] Furthermore, such as Figure 48 As shown, the detection element 12 is soldered onto the PCB board 16, and LED lights 163 (not shown) are soldered around the detection element 12 on the PCB board 16. A light-diffusing sheet 1881 is provided between the detection element 12 and the upper housing 141. The light emitted by the LED lights 163 is diffused by the light-diffusing sheet 1881 and then projected onto the lower surface of the button 11. The upper housing 141 is recessed towards the light-diffusing sheet 1881, and a light-diffusing sheet mounting groove 1882 is provided that matches the shape of the light-diffusing sheet 1881. When the upper housing 141 covers the PCB board mounting shell 148, the light-diffusing sheet 1881 is limited by the light-diffusing sheet mounting groove 1882, and the lower surface of the light-diffusing sheet 1881 abuts against the detection element 12 and is supported by the detection element 12.

[0241] Furthermore, such as Figure 48 and Figure 49As shown, the upper housing 141 is provided with a PCB housing positioning part 1481 and a PCB housing buckle 1482 facing the PCB board mounting housing 148. The PCB board mounting housing 148 is provided with a second fastening position 1483 adapted to the PCB housing buckle 1482 at a corresponding position. When the upper housing 141 covers the PCB board mounting housing 148, the PCB housing positioning part 1481 abuts against the outer side wall of the PCB mounting housing to position the PCB mounting housing; the PCB housing buckle 1482 is fastened to the second fastening position 1483 to fix the PCB mounting housing to the upper housing 141.

[0242] Furthermore, such as Figure 49 As shown, an insulating plate 149 is provided between the power board 17 and the PCB board mounting shell 148, and the insulating plate 149 is fixedly connected to the lower shell 142. The insulating plate 149 has pin header through holes 1491 at corresponding positions of the pin headers 161. The size of the pin header through holes 1491 is adapted to the size of the pin headers 161 and the female headers 173, so that the pin headers 161 pass through the pin header through holes 1491 and are then inserted into the female headers 173. The insulating plate 149 is fixed to the lower shell 142 by screws, and the insulating plate 149 has a downward protruding part for abutting the power board 17, which is used to press and fix the power board 17 to the lower shell 142. The function of the insulating plate 149 is to isolate the power board 17. Since the PCB is connected to the upper housing 141, the PCB board 16 and the power board 17 are electrically connected through the pin header 161 and the socket 173. When the upper housing 141 is opened, the PCB board 16 and the power board 17 are separated. In order to prevent the power board 17 from being exposed and causing the user to be at risk of electric shock, the insulating plate 149 is set between the PCB board 16 and the power board, which also meets the safety requirements.

[0243] Furthermore, the outer side wall of the lower housing 142 is provided with a first positioning part 1424, and the inner side wall of the upper housing 141 is provided with a second positioning part 1418. When the upper housing 141 covers the lower housing 142, the second positioning part 1418 is sleeved on the first positioning part 1424, and the inner surface of the second positioning part 1418 at least partially abuts against the outer surface of the first positioning part 1424, so that the upper housing 141 is positioned by the lower housing 142 in the horizontal direction. Detailed technical details regarding the first positioning part 1424 and the second positioning part 1418 have been described above and will not be repeated here.

[0244] In some embodiments, such as Figure 50As shown, the power board 17 is equipped with an on / off switch 177, which can control the AC power supply to the power board 17. The on / off switch 177 is a mechanical switch, soldered to the power board 17, which can cut off the AC power supply. It can provide power outage protection during switch installation, limit the use of the smart switch, and enable the smart switch system to restart after a power outage.

[0245] Furthermore, such as Figure 50 As shown, the PCB board 16 has a first clearance hole 1771 at the corresponding position of the on / off switch 177, and the surface of the lower housing 142 facing the button 11 has a second clearance hole 1772 at the corresponding position of the on / off switch 177. The shapes of the first clearance hole 1771 and the second clearance hole 1772 are adapted to the on / off switch 177, so that the on / off switch 177 protrudes at least partially from the lower housing 142 after passing through the first clearance hole 1771 and the second clearance hole 1772. The surface of the lower housing 142 facing the button 11 can be understood as the upper surface of the lower housing 142, that is, the upper surface of the isolation cover 18. The power switch is set on the power board 17 and passes through the PCB board 16 and the isolation cover 18 above, exposing the isolation cover 18, so that the on / off switch 177 can be pressed after opening the upper housing 141, and the on / off switch 177 controls the power supply to and from the power board 17 and the PCB board 16.

[0246] Furthermore, such as Figure 20 and Figure 21 As shown, the PCB board 16 has at least one LED 163 at each corresponding position of each button 11. The light emitted by the LED 163 is projected onto the first surface of the button 11; the first surface is the side of the button 11 facing the housing 14. The first surface is the lower surface of the button 11. Each button 11 has multiple corresponding LEDs 163, which are symmetrically arranged around the detection element 12 corresponding to the button 11. In one specific embodiment, 4 or 6 LEDs 163 are symmetrically soldered to both sides of each detection element 12 on the PCB board 16.

[0247] Furthermore, such as Figure 22As shown, the button 11 is provided with a light guide portion 114. The light emitted by the LED lamp 163 is guided by the light guide portion 114 to the third surface of the button 11. The third surface is set as the side of the button 11 facing away from the housing 14. The shape of the light guide portion 114 is set to a predetermined shape, so that the light guide portion 114 displays a predetermined pattern 1141 corresponding to the predetermined shape on the third surface of the button 11. The light guide portion 114 is integrally formed or fixedly connected to the button 11, and can guide the light inside the button 11 to the outside of the button 11. Specifically, the button 11 is injection molded from a light-transmitting material, and an opaque coating 117 is coated on the outer surface of the button 11. The predetermined pattern 1141 is laser-engraved on the outer surface of the button 11, so that the opaque coating 117 is removed by laser engraving to form the light guide portion 114. The light of the LED shines through the laser-engraved part of the button 11, displaying the predetermined pattern 1141 on the outer surface of the button 11. The predetermined pattern 1141 includes graphics or text. The upper housing 141 is magnetically attached to the laser-engraved button 11, allowing users to freely select the predetermined pattern 1141 or a combination of multiple patterns. The magnetic structure enables quick switching of the upper housing 141, thereby quickly switching the content displayed on the button 11.

[0248] Furthermore, such as Figure 21 As shown, the PCB board 16 is disposed on the lower housing 142; the lower housing 142 includes a bottom shell 19 and an isolation cover 18. The isolation cover 18 covers the bottom shell 19 and forms a receiving cavity with the bottom shell 19, and the PCB board 16 is accommodated inside the receiving cavity. Specifically, the isolation cover 18 is snapped onto the bottom shell 19 by isolation cover buckles 186. At least one isolation cover buckle 186 is provided on the edge of the isolation cover 18 facing the bottom shell 19, and the isolation cover 18 is snapped onto the bottom shell 19 by the isolation cover buckles 186. The bottom shell 19 is a groove-shaped housing 14 with an opening at the top. The shape of the isolation cover 18 is adapted to the shape of the opening at the top of the bottom shell 19, and the edge of the isolation cover 18 extends outward to form a fastening eave 182. The isolation cover 18 is disposed on the opening at the top of the bottom shell 19, and the fastening eave 182 is attached to the upper surface of the bottom shell 19. The isolation cover 18 serves as an electrical isolation cover. Since the power board 17 carries high voltage, the power board 17 and the PCB board 16 cannot be exposed to the outside, so as to prevent the user from being at risk of electric shock after opening the upper casing 141.

[0249] Furthermore, such as Figure 8 and Figure 11As shown, the side of the upper housing 141 facing the button 11 is provided with a first positive marking 14171 to indicate the positive direction of the upper housing 141; the side of the upper housing 141 facing the isolation cover 18 is provided with a second positive marking 14172, and the side of the isolation cover 18 facing the upper housing 141 is provided with a third positive marking 185. The second positive marking 14172 and the third positive marking 185 indicate the same direction and are used to prevent mistaken installation when the upper housing 141 is placed on top of the lower housing 142. The first positive marking 14171 can be an arrow, text, or a shape mark, used to prevent mistaken installation of the button 11.

[0250] like Figure 21 and Figure 19 As shown, the isolation cover 18 is disposed between the button 11 and the PCB board 16. A light-diffusing cover 183 is respectively disposed at a corresponding position of each button 11 on the isolation cover 18. The light-diffusing cover 183 covers the LED light 163 corresponding to each button 11. The light emitted by the LED light 163 is diffused by the light-diffusing cover 183 and then projected onto the button 11. Specifically, the light-diffusing cover 183 disposed at a corresponding position of each button 11 on the isolation cover 18 can be understood as follows: the light-diffusing cover 183 is disposed below the center of the button 11, and the light-diffusing cover 183 is located above the LED light 163. The light emitted by the LED light 163 is diffused by the light-diffusing cover 183 and then projected onto the button 11. Specifically, the light-diffusing mask 183 extends towards the isolation plate with four light-diffusing mask clips 1831. The isolation plate has isolation cover through holes 1832 with shapes matching the light-diffusing mask 183. The sidewall of the isolation cover through holes 1832 is provided with light-diffusing mask fastening positions 1833. The four light-diffusing mask clips 1831 are fastened to the light-diffusing mask fastening positions 1833, so that the light-diffusing mask 183 is snapped onto the isolation plate. In a preferred embodiment, the light-diffusing mask 183 is made of a transparent material that has been atomized, or is made of an opaque material, such as white light-transmitting plastic, which has light transmittance and light-diffusing properties. In a preferred embodiment, the light-diffusing mask 183 is injection molded from PC plastic.

[0251] Furthermore, such as Figure 19 and Figure 21 As shown, the projection of the light-diffusing mask 183 onto the third surface of the button 11 covers the predetermined pattern 1141. The third surface is the upper surface of the button 11. Since the function of the light-diffusing mask 183 is to uniformly distribute the light emitted by the LED and project it onto the light guide 114, which then transmits the light, ensuring uniform brightness of the light transmitted through the light guide 114, the surface of the light-diffusing mask 183 facing the button 11 must cover the predetermined pattern 1141 of the light guide 114 to ensure uniform brightness of the predetermined pattern 1141.

[0252] Furthermore, such as Figure 19 and Figure 21 As shown, the surface of the light-diffusing cover 183 facing the button 11 is rectangular, and the light-diffusing cover 183 is a cuboid cover with an opening at the bottom. The surface of the light-diffusing cover 183 facing the button 11 is the upper surface of the light-diffusing cover 183. This surface can be rectangular, square, circular, or other shapes. In a preferred embodiment, the surface of the light-diffusing cover 183 facing the button 11 is rectangular, and the light-diffusing cover 183 is a cuboid cover with an opening at the bottom. The advantages are that the predetermined pattern 1141 on the button 11 is generally text, including Chinese or English, and the text is generally arranged horizontally. Using a rectangular light-diffusing cover 183 helps to cover all the text, making the text light-transmitting uniformly. Furthermore, in some preferred embodiments, the smart switch has four buttons 11, and correspondingly four light-diffusing covers 183. Using a rectangular light-diffusing cover 183 has a foolproof function.

[0253] Furthermore, such as Figure 19 and Figure 21 As shown, the detection element 12 is covered by the light-diffusing cover 183. The light-diffusing cover 183 has a pressure-sensitive through-hole 1834 at a corresponding position on the detection element 12. The button 11 has a contact portion 113 at a corresponding position on the detection element 12. The contact portion 113 passes through the pressure-sensitive through-hole 1834 and is positioned above the detection element 12. When the button 11 responds to the operating force and generates the displacement, the contact portion 113 presses against and triggers the detection element 12. The fact that the light-diffusing cover 183 has a pressure-sensitive through-hole 1834 at a corresponding position on the detection element 12 can be understood as the light-diffusing cover 183 covering the detection element 12 and having the pressure-sensitive through-hole 1834 directly above the detection element 12, so that the contact portion 113 is positioned directly above the detection element 12, improving the reliability of triggering the detection element 12. Figure 9 and Figure 6 As shown, the contact portion 113 is a column extending from the button 11 toward the detection element 12. Its cross-section perpendicular to the extension direction is designated as the first cross-section. The size of the pressure-sensitive through-hole 1834 is larger than the size of the first cross-section, and there is a certain gap between the contact portion 113 and the pressure-sensitive through-hole 1834. The first shape, composed of two intersecting and perpendicular rectangles, can be understood as a cross shape, designed to prevent shrinkage caused by localized thickening of the contact portion 113 during injection molding, which could affect the triggering of the detection element 12. Since the movement generated when the button 11 is pressed is a composite motion of displacement and rotation, and the button 11 can tilt in multiple directions, setting a certain gap between the contact portion 113 and the pressure-sensitive through-hole 1834 prevents interference between them when the button 11 moves.

[0254] Furthermore, such as Figure 19 and Figure 21 As shown, the light-diffusing cover 183 protrudes from the isolation cover 18. The height of the light-diffusing cover 183 protruding from the isolation cover 18 is adapted to the distance between the isolation cover 18 and the PCB board 16, so that the distance between the surface of the light-diffusing cover 183 facing the button 11 and the PCB board 16 is greater than 3mm. Since the light-diffusing cover 183 has a touch-sensitive through-hole 1834, in order to prevent users from touching the touch-sensitive through-hole 1834 and getting electric shock, there must be sufficient electrical clearance and creepage distance between the light-diffusing cover 183 and the PCB board 16. Therefore, the height of the light-diffusing cover 183 protruding from the isolation cover 18 is designed so that the distance between the upper surface of the light-diffusing cover 183 and the PCB board 16 is greater than 3mm, ensuring user safety.

[0255] Furthermore, such as Figure 8 and Figure 11 As shown, the upper housing 141 has a light-transmitting through-hole 1419 with a shape matching the light-transmitting cover 183 at a corresponding position. When the upper housing 141 covers the lower housing 142, the light-transmitting cover 183 is accommodated within the light-transmitting through-hole 1419. Specifically, the light-transmitting cover 183 is rectangular, and correspondingly, the light-transmitting through-hole 1419 is also a rectangular through-hole. The function of the light-transmitting through-hole 1419 is twofold: first, it allows light to pass through, enabling the light from the light-transmitting cover 183 to be projected onto the lower surface of the button 11; second, after passing through the light-transmitting through-hole 1419, the light-transmitting cover 183 is positioned below the button 11, further shortening the distance between the light-transmitting cover 183 and the button 11, thus reducing light attenuation.

[0256] In a preferred embodiment, such as Figure 23 As shown, the number of light-diffusing masks 183 is one more than the number of buttons 11, and correspondingly, the number of light-diffusing mask through-holes 1419 is one more than the number of buttons 11. Specifically, there are four buttons 11, five light-diffusing masks 183, and five corresponding light-diffusing mask through-holes 1419, which are arranged in a corresponding manner to the light-diffusing masks 183. Using five light-diffusing masks 183 facilitates the switching between single-key and multi-key operation of the buttons 11, as detailed below. Furthermore, since the four buttons 11 are symmetrically arranged, and the four light-diffusing masks 183 corresponding to the buttons 11 are also symmetrically arranged, it is difficult to distinguish the correspondence between the light-diffusing mask through-holes 1419 and the light-diffusing masks 183 when installing the upper housing 141. Therefore, setting five light-diffusing masks 183 has a foolproof function, enabling quick identification of the correspondence between the light-diffusing mask through-holes 1419 and the light-diffusing masks 183, thereby facilitating quick installation of the upper housing 141. In other embodiments, the number of light-diffusing masks 183 is the same as the number of buttons 11, such as... Figure 11As shown, the light-diffusing mask 183 corresponds one-to-one with the button 11, which can reduce the use of the light-diffusing mask 183 and save costs.

[0257] In another embodiment, such as Figures 51-54 As shown, a waterproof and light-transmitting element 41 is provided between the isolation cover 18 and the bottom shell 19. The waterproof and light-transmitting element 41 is sealed to the bottom shell 19, thereby forming a sealed cavity. The sealed cavity houses the detection element 12, the wireless communication module 13, the PCB board 16, and the LED light 163. The waterproof and light-transmitting element 41 can be understood as a waterproof housing 14, made of soft materials such as silicone or rubber, or plastic. Its function is to seal to the bottom shell 19, forming a waterproof sealed cavity, protecting the electronic components from water and moisture, and also providing electrical isolation.

[0258] Furthermore, such as Figure 52 and Figure 53 As shown, a sealing portion 187 extends from the edge of the isolation cover 18 towards the waterproof and light-transmitting component 41. The sealing portion 187 presses the edge of the waterproof and light-transmitting component 41 against the bottom shell 19 to achieve a sealed connection between the waterproof and light-transmitting component 41 and the bottom shell 19. The direction from the isolation cover 18 to the bottom of the bottom shell 19 is designated as the fifth direction. In this fifth direction, the gap between the sealing portion 187 and the bottom shell 19 is less than the thickness of the edge of the waterproof and light-transmitting component 41. The sealing portion 187 can be understood as a pressure rib surrounding the isolation cover 18. The sealing portion 187 pressing the edge of the waterproof and light-transmitting component 41 against the bottom shell 19 can be understood as the sealing portion 187 and the bottom shell 19 clamping the edge of the waterproof and light-transmitting component 41 in the middle to achieve a sealed connection between the waterproof and light-transmitting component 41 and the bottom shell 19. The gap between the sealing part 187 and the bottom shell 19 is less than the thickness of the edge of the waterproof and light-transmitting element 41. This can be understood as the sealing part 187 and the bottom shell 19 clamping the edge of the waterproof and light-transmitting element 41 with an interference fit in the middle to improve the sealing performance. The fifth direction is as follows: Figure 52 In this embodiment, the direction indicated by the middle arrow is the same as the third direction.

[0259] Furthermore, such as Figure 52As shown, the waterproof light-transmitting component 41 has a light-transmitting part 411 at a corresponding position on the LED lamp 163. The light-transmitting part 411 is integrally formed or sealed to the waterproof light-transmitting component 41. The light-transmitting part 411 is configured to allow light to pass through from one side to the other. The light-transmitting part 411 is located between the button 11 and the LED lamp 163. The light-transmitting part 411 is made of a light-transmitting material and is used to transmit the light emitted by the LED lamp 163 to the lower surface of the button 11. In addition, the light-transmitting part 411 has a light-uniforming function, which can uniformly project the light emitted by the LED lamp 163 onto the light guide part 114 of the button 11, so that the text or pattern displayed on the upper surface of the button 11 is illuminated uniformly. The sealed connection can be understood as a connection method that can be sealed, including the use of sealant, separate injection molding, or other feasible connection methods. In a specific embodiment, the light-transmitting part 411 and the waterproof light-transmitting component 41 are integrally injection molded from white silicone, so that it has the functions of light transmission and light uniformity.

[0260] Furthermore, the light-transmitting portion 411 is disposed between the light guide portion 114 and the LED lamp 163, and the projection of the light-transmitting portion 411 onto the third surface of the button 11 covers the predetermined pattern 1141. The third surface is the upper surface of the button 11. The function of the light-transmitting portion 411 is to uniformly project the light emitted by the LED lamp 163 onto the light guide portion 114 of the button 11, causing the predetermined pattern 1141 on the upper surface of the button 11 to emit light. Therefore, the light-transmitting portion 411 needs to cover the predetermined pattern 1141 so that all parts of the predetermined pattern 1141 can emit light, and the light emission is uniform.

[0261] Furthermore, such as Figure 52 and Figure 54 As shown, the light-transmitting portion 411 is disposed between the button 11 and the detection element 12. The button 11 abuts against the light-transmitting portion 411 and triggers the detection element 12 through the light-transmitting portion 411. The button 11 triggering the detection element 12 through the light-transmitting portion 411 can be understood as the button 11 abutting against the upper surface of the light-transmitting portion 411. Since the light-transmitting portion 411 is disposed between the button 11 and the detection element 12, when the button 11 responds to the operating force and undergoes displacement, it presses against and causes a portion of the light-transmitting portion 411 to displace, thus pressing against and triggering the detection element 12. The advantage of the button 11 indirectly pressing against the detection element 12 through the light-transmitting portion 411 is that, since the light-transmitting portion 411 is made of a soft material, it has a buffering effect on the pressure applied to the button 11, preventing damage to the detection element 12 when the button 11 is pressed with excessive force.

[0262] Furthermore, such as Figure 53As shown, the isolation cover 18 has an isolation cover through hole 1832 at the corresponding position of the light-transmitting part 411. The light-transmitting part 411 passes through the isolation cover through hole 1832 and is at least partially exposed on the upper surface of the isolation cover 18. Since the isolation cover 18 presses and fixes the waterproof light-transmitting component 41 to the bottom shell 19, and the light-transmitting part 411 needs to pass through the isolation cover 18 to project the light of the LED lamp 163 onto the lower surface of the button 11, the isolation cover 18 has an isolation cover through hole 1832 to allow the light-transmitting part 411 to pass through the isolation cover 18. The fact that the light-transmitting part 411 is at least partially exposed on the upper surface of the isolation cover 18 can be understood as the light-transmitting part 411 protruding from the upper surface of the isolation cover 18, or flush with or below the upper surface of the isolation cover 18, so that the contact part 113 of the button 11 can contact the light-transmitting part 411. Since the button 11 presses against and triggers the detection element 12 below through the light-transmitting part 411, in a preferred embodiment, the light-transmitting part 411 is protruding from the isolation cover 18, which makes it easier for the button 11 to press against the light-transmitting part 411. At the same time, the light-transmitting part 411 provides space for the detection element 12 below.

[0263] Furthermore, when the button 11 responds to the operating force and generates the displacement, the button 11 presses against the light-transmitting part 411 and undergoes elastic deformation. When the operating force is removed, the light-transmitting part 411 returns to its initial state under the action of its own elastic force, and drives the button 11 back to its initial position. Here, the light-transmitting part 411 driving the button 11 back to its initial position can be understood as the light-transmitting part 411 being elastic, capable of elastic deformation, and generating a restoring force to overcome the elastic deformation acting on the button 11. Further, as... Figure 54 As shown, the button 11 has a protruding abutment 113 facing the light-transmitting part 411. The abutment 113 is composed of four square pressing units, which occupy most of the upper surface of the light-transmitting part 411. The abutment 113 evenly presses against the upper surface of the light-transmitting part 411 to prevent the light-transmitting part 411 from slipping due to single-point pressing, thus preventing it from being triggered. In summary, the waterproof light-transmitting component 41 of this embodiment has at least four functions: 1. Sealing and waterproofing to protect internal electronic components; 2. Uniform light transmission, projecting the light emitted by the LED onto the button 11; 3. Buffering the pressure between the button 11 and the detection element 12 to prevent damage to the detection element 12 when the button 11 is pressed with excessive force; 4. Providing a reset force to help the button 11 return to its initial position. Compared with traditional waterproof components, the waterproof light-transmitting component 41 of this embodiment is multi-functional, simplifies the internal structure of the switch, reduces the number of parts, simplifies the assembly steps, and reduces manufacturing costs.

[0264] In another embodiment, such as Figure 55 and Figure 56As shown, the lower housing 142 is provided with at least one sound generator 189, which is electrically connected to the PCB board 16 and is used to emit a sound in response to the triggering of the detection element 12. The sound generator 189 emitting a sound in response to the triggering of the detection element 12 can be understood as using the sound generator 189 as feedback for the button 11, emitting a sound to indicate to the user that the detection element 12 has been triggered. Generally, switches use the tactile feedback of the detection element 12 itself as trigger feedback. During the pressing process, the elasticity of the detection element 12 changes abruptly, and the user judges whether the detection element 12 is easily triggered based on the tactile sensation. However, this design has at least two drawbacks: 1. When the detection element 12 is insensitive or damaged, pressing the detection element 12 provides tactile feedback, but the switch cannot detect the signal from the detection element 12 and cannot control the power on / off of the controlled device. In this case, the feedback of the button 11 does not correspond to the operation of the controlled device, which may lead to misjudgment by the user, who may mistakenly believe that the controlled device is on or off. When the controlled device is an appliance with a delayed activation, the user's misjudgment will be more obvious; 2. When the feedback from the detection element 12 is not obvious, or the user's tactile sensitivity is not high, the user may not feel the triggering of the detection element 12, which will cause inconvenience to the user. In this embodiment, a sound generator 189 is used as the trigger feedback. The sound generator 189 is soldered to the PCB board 16, and its feedback is synchronized with the control of the controlled device. When the detection element 12 is damaged, pressing the detection element 12 will not trigger feedback, and the user will not make a misjudgment. Moreover, the volume of the sound generator 189 is adjustable, so even users with low sensory sensitivity can still feel the feedback of the button 11, making it convenient to use.

[0265] Furthermore, such as Figure 56As shown, the sound generator 189 is configured as a speaker 1891, and the lower housing 142 is provided with a speaker mounting position 1892. The speaker 1891 is fixedly connected to the speaker mounting position 1892. The sound generator 189 can also be a buzzer or other sound-producing device. The speaker mounting position 1892 can be understood as a recessed groove on the surface of the lower housing 142, its shape matching the shape of the speaker 1891. This ensures that when the speaker 1891 is mounted in the speaker mounting position 1892, the upper surface of the speaker 1891 does not protrude too much from the surface of the lower housing 142, and the upper housing 141 is not pushed up by the speaker 1891 when it covers the lower housing 142. Alternatively, the speaker mounting position 1892 can be located inside the lower housing 142, with the sound-producing surface of the speaker 1891 facing outwards from the lower housing 142 when placed in the speaker mounting position 1892. The speaker 1891 can be disposed on the upper surface of the lower housing 142 or on the side of the lower housing 142. When the speaker 1891 is disposed on the upper surface of the lower housing 142, the upper housing 141 covers the lower housing 142, hiding the speaker 1891 under the upper housing 141, thus improving the aesthetics of the switch. The speaker 1891 is fixedly connected to the speaker mounting position 1892 by means of snap-fit, screw connection, adhesive, or other feasible connection methods.

[0266] In one specific embodiment, such as Figure 56As shown, the speaker mounting position 1892 is a cylindrical structure extending downward from the isolation cover 18. The inner diameter of the speaker mounting position 1892 is clearance-fitted with the speaker 1891. The speaker 1891 includes a speaker body 1893 and a speaker base 1894 disposed at the bottom of the speaker body 1893. The speaker base 1894 protrudes from the outer side wall of the speaker body 1893. The speaker 1891 is inserted from below the speaker mounting position 1892. The upper surface of the speaker base 1894 abuts against the lower surface of the speaker mounting position 1892. Adhesive is pasted on the upper surface of the speaker base 1894, or adhesive is pasted on the side surface of the speaker body 1893, so that the speaker 1891 is fixedly connected to the speaker mounting position 1892 by adhesive. The speaker base 1894 is electrically connected to a speaker wire 1895. A speaker connector 1896 is provided at the end of the speaker wire 1895. A speaker socket 1897, compatible with the speaker connector 1896, is soldered onto the PCB board 16. The speaker connector 1896 is inserted into the speaker socket 1897 to achieve an electrical connection between the speaker 1891 and the PCB board 16. When installing the isolation cover 18, the speaker 1891 is first fixed to the speaker mounting position 1892, then the speaker connector 1896 is inserted into the speaker socket 1897, and finally the isolation cover 18 is snapped onto the bottom shell 19. Furthermore, the isolation cover 18 has at least one sound-emitting hole 1898 at the corresponding position of the speaker 1891. The sound-emitting hole 1898 is a through hole penetrating the isolation cover 18, allowing sound emitted by the speaker 1891 to pass through the isolation cover 18.

[0267] In some embodiments, such as Figures 24-26 As shown, the button 11 can switch between single-button and multi-button configurations, and simultaneously, the corresponding configuration size changes according to the number of configurations, thereby realizing the switching of single-channel or multi-channel control functions. Specifically, as shown... Figure 24The diagram shows a single-button switch 11. The button 11 is enlarged to cover the entire upper surface of the upper housing 141. Button clips 112 are located at the four corners of the button 11, and their positions correspond to the engagement positions 1415 at the four corners of the upper housing 141. Button positioning pins 111 are respectively provided at the four corners of the button 11, corresponding to the positions of the first positioning holes 1513. The button positioning pins 111 are inserted into the first positioning holes 1513 for positioning. The advantage of placing the button positioning pins 111 at the four corners of the button 11 is that it maximizes the distance between the button positioning pins 111, resulting in more accurate positioning. It is worth noting that in this embodiment, there is only one detection element 12 and one light-diffusing mask 183, but there are five light-diffusing mask through-holes 1419, which are arranged side by side at both ends of the upper housing 141. Three light-diffusing mask through-holes 1419 are arranged at one end, and the detection element 12 is provided below the light-diffusing mask 183 corresponding to the light-diffusing mask 1419 located in the middle position. The button 11 extends a contact portion 113 at the corresponding position of the detection element 12. When the button 11 is pressed, the contact portion 113 triggers the detection element 12. The isolation cover 18 does not have a light-diffusing mask fastening position 1833 and an isolation cover through-hole 1832 at the corresponding positions of the other light-diffusing mask through-holes 1419, which further saves costs.

[0268] Additionally, the button 11 has at least one supporting portion 1122 protruding towards the housing 14 at the end away from the contact portion 113. This supporting portion abuts against the housing 14, thereby supporting the end of the button 11 away from the contact portion 113 and preventing this end of the button 11 from being pressed. The supporting portion 1122 supports the button 11, providing a fulcrum so that when the entire button 11 is pressed, the button 11 pivots based on the supporting portion 1122, and the end near the contact portion 113 moves downward, thereby triggering the detection element 12 at the contact portion 113. Simultaneously, this prevents the user from mistakenly believing that the detection element 12 has been triggered when the user presses the end of the button 11 away from the contact portion 113, even if the detection element 12 is not triggered.

[0269] like Figure 25The diagram shows a schematic of a dual-button switch 11. The buttons 11 are rectangular, arranged side-by-side. Button clips 112 are located at the four corners of each button 11, engaging with the engagement positions 1415 of the middle cover. Button positioning pins 111 are located at the four corners of each button 11, corresponding to the positions of the first positioning holes 1513. The button positioning pins 111 are inserted into the first positioning holes 1513 for positioning. In this embodiment, there are two detection elements 12 and two light-diffusing masks 183, but the light-diffusing mask has five light-transmitting holes 1419. Each end of the button 11 facing the lower housing 142 extends a contact portion 113. The position of the contact portion 113 corresponds to the position of the pressure-sensitive through-hole 1834 of the light-diffusing mask 183. The contact portion 113 passes through the pressure-sensitive through-hole 1834 and is positioned above the detection element 12. Figure 26 The diagram shows a three-button switch 11. The three buttons 11 include a rectangular button 11 and two square buttons 11. The three buttons 11 are arranged in a single unit on the upper housing 141. Each button 11 has a button clip 112 at one of its four corners to engage with the engagement position 1415 of the middle cover. In this embodiment, there are three detection elements 12 and three light-diffusing covers 183, but the light-diffusing cover has five light-transmitting holes 1419. Each end of the rectangular button 11 facing the lower housing 142 extends a contact portion 113. The middle portion of each of the two square buttons 11 extends a contact portion 113. The position of each contact portion 113 corresponds to the position of the pressure-sensitive through-hole 1834 of the light-diffusing cover 183. The contact portion 113 passes through the pressure-sensitive through-hole 1834 and is positioned above the detection element 12. The isolation cover 18 does not have a light-diffusing cover fastening position 1833 or an isolation cover through hole 1832 at the corresponding positions of the light-diffusing cover through holes 1419 of other light-diffusing covers, further saving costs. It is worth noting that, compared with the switch structure of single button 11 and multi-button 11, only the structure of button 11 and isolation cover 18 are different, while other parts are interchangeable. This design saves mold costs, design costs, and manufacturing costs; and users can flexibly switch between single button and multi-button, with low replacement costs.

[0270] In addition, such as Figure 25 and Figure 26As shown, when button 11 is elongated and covers two light-transmitting holes 1419 of the light-diffusing mask, button 11 has at least one supporting portion 1122 protruding from the end away from the contact portion 113 towards the housing 14. This supporting portion 1122 abuts against the housing 14, thereby supporting the end of button 11 away from the contact portion 113 and preventing this end of button 11 from being pressed. The function of the supporting portion 1122 is to support button 11, providing a fulcrum for button 11. When button 11 is pressed as a whole, button 11 pivots based on the supporting portion 1122, and the end near the contact portion 113 moves downward, thereby triggering the detection element 12 at the contact portion 113. At the same time, this prevents the user from mistakenly believing that the detection element 12 has been triggered when the user presses the end of button 11 away from the contact portion 113, even if the detection element 12 is not triggered.

[0271] This embodiment proposes an intelligent switch system comprising: a cloud platform, a gateway, an intelligent terminal, and at least one intelligent switch. The intelligent switch can be any switch device configured with a wireless communication module 13, which can be, for example, at least one of a Bluetooth wireless communication module 13, a Wi-Fi wireless communication module 13, and a radio frequency wireless communication module 13. In this embodiment, the intelligent switch is a wall switch. The intelligent terminal can be, for example, a mobile phone, tablet computer, computer, intelligent vehicle system, or intelligent home appliance. The intelligent terminal can interact with the cloud platform via a Wi-Fi network (router) or via a Bluetooth gateway. The gateway can be any device capable of communicating with both the cloud platform and the intelligent switch, such as a wall switch equipped with both a Wi-Fi wireless communication module 13 and a radio frequency wireless communication module 13, or a network device dedicated to data interaction and processing, such as a Wi-Fi gateway or a router. In this embodiment, the gateway is configured with a separate voice module, serving as a voice gateway. The cloud platform can be any device or combination of devices with data storage and processing capabilities and capable of interacting with the gateway, such as a server, on which the required programs can be deployed.

[0272] In a preferred embodiment, such as Figure 27 and Figure 28 As shown, the wall smart switch 101 also includes a display screen 164, which is electrically connected to the wireless communication module 13; the button 11 is positioned to match the display screen 164.

[0273] The wireless communication module 13 is used for:

[0274] The display screen 164 is controlled to display the function identifier of the button 11; the function identifier is used to represent the current function of the button 11;

[0275] The trigger signal of the button 11 being triggered is obtained directly or indirectly, and the trigger result corresponding to the current function is executed.

[0276] The wireless communication module 13 is further used for:

[0277] When the function of the button 11 changes, the system directly or indirectly receives and stores an identifier update instruction sent by a smart terminal, and updates the function identifier corresponding to the button 11 displayed on the display screen 164 based on the identifier update instruction, so that the function identifier can represent the current function of the button 11; the identifier update instruction carries the current function information of the button 11.

[0278] When there are too many switch buttons 11, users easily forget the correspondence between buttons 11 and lights. With the introduction of smart switches, the switch may represent not only a single light but also many scene modes, such as "away mode" and "all on mode," making the functions represented by the switch more complex and harder for users to remember. Based on this, existing technologies offer some customer-customized laser engraving technology, allowing users to choose to laser engrave the text or icons they need on the switch. However, this solution is difficult to modify later, and the customization service process is complex. On the other hand, although many smart home control screens provide control of whole-house smart lighting or offer scene mode buttons 11 on the control screen, full-size touchscreens are expensive, and the complex interface and operation of touchscreens are very unfriendly to the elderly. Therefore, a simple, low-cost switch that can dynamically configure the name or icon of the function displayed on button 11 is needed. The smart switch provided by the present invention carries a display screen 164 that can display the functions of the physical buttons 11 of the switch. The function representation of each button 11 displayed on the display screen 164 can be dynamically configured. For smart switches with a large number of buttons 11, users can easily change the function representation of the corresponding area on the display screen 164 based on the current function of each button 11, so that the function of the buttons 11 of the smart switch can be changed and marked flexibly.

[0279] Furthermore, directly or indirectly acquiring the trigger signal of the button 11 being triggered, and controlling the execution of the trigger result corresponding to the current function; including:

[0280] The system acquires the trigger signal of the button 11 being triggered, determines the key value information of the triggered button 11 based on the trigger signal, matches the target function in the stored function mapping table based on the key value information, and controls the trigger result indicated by the target function to be executed. The function mapping table of the button 11 defines the trigger relationship between at least one key value information and at least one trigger result, which is directly or indirectly sent by the user after being freely determined on the smart terminal and stored in the local memory of the wireless communication module 13.

[0281] In this embodiment, the smart switch can control the execution of the trigger result corresponding to the trigger signal based on the locally stored function mapping table, without relying on cloud or gateway control, thus achieving the goal of control even when the network is disconnected.

[0282] Furthermore, the system directly or indirectly acquires the trigger signal of the button 11 being triggered, and controls the execution of the trigger result corresponding to the current function; it also includes:

[0283] The trigger signal of the button 11 being triggered is obtained, and the key value information of the triggered button 11 is determined based on the trigger signal;

[0284] The key value information is uploaded to the cloud so that the cloud can match the target function in the stored function mapping table based on the key value information; the function mapping table is defined by the user through the smart terminal and pre-stored in the cloud; the function mapping table of button 11 defines the trigger relationship between at least one key value information and at least one trigger result.

[0285] The above triggering result can be understood as at least one executable function of at least one controlled device. The function involved in the triggering result may include turning the device on or off, or switching the specific function of the device, such as a controlled entertainment device playing specific music or video, or a curtain control device closing the curtains; in this embodiment, the smart switch is a wall switch with multiple relay 175 control channels, then the triggering result includes turning the relay 175 of at least one control channel of the smart switch on or off.

[0286] In this embodiment, the smart switch uploads the trigger signal to the cloud, which then judges and issues corresponding control commands, enabling a wider range of control needs to be met.

[0287] Furthermore, in some embodiments, the current control command may also be a voice control command uploaded by the user through a gateway; furthermore, the wireless communication module 13 is also used for:

[0288] The system executes control commands issued directly or indirectly from the cloud, and controls the execution of triggering results indicated by the control commands. The control commands are generated by the cloud after parsing voice control information and matching the target function in a stored function mapping table. The voice control information is generated by a gateway in response to external voice control information. The parsing result contains at least corresponding key-value information. The function mapping table is defined by the user via a smart terminal and pre-stored in the cloud. The function mapping table of button 11 defines a triggering relationship between at least one key-value information and at least one triggering result.

[0289] In this embodiment, voice control is introduced. Users can upload voice control information through a voice gateway, and then the cloud can issue control commands based on the parsing of the voice control information, freeing up users' hands and realizing more intelligent linkage control.

[0290] Furthermore, when the function of button 11 changes, an identifier update command sent by a smart terminal is received and stored directly or indirectly, and the function identifier corresponding to button 11 displayed on the display screen 164 is updated based on the identifier update command; including:

[0291] The system directly or indirectly receives and stores an identifier update instruction sent by a smart terminal, and updates the function identifier displayed on the display screen 164 corresponding to the button 11 based on the identifier update instruction; the identifier update instruction is also used to trigger the smart terminal to upload the identifier update instruction to the cloud, so that the cloud updates the stored function mapping table according to the correspondence between the key value information and the function identifier carried in the identifier update instruction.

[0292] In this embodiment, when the function of a smart switch or a button 11 changes, the user will update the function mapping table stored in the cloud and the smart switch in real time through a smart terminal (such as a mobile phone), so that the key value information of each smart switch in the function mapping table corresponds to the corresponding function identifier after the change, in order to prevent the problem that the trigger result of the actual control does not correspond after the function of button 11 changes.

[0293] The above triggering result can be understood as at least one executable function of at least one controlled device. The function involved in the triggering result may include turning the device on or off, or switching the specific function of the device, such as a controlled entertainment device playing specific music or video, or a curtain control device closing the curtains; in this embodiment, the smart switch is a wall switch with multiple relay 175 control channels, then the triggering result includes turning the relay 175 of at least one control channel of the smart switch on or off.

[0294] In this embodiment, the smart switch is a wall switch. If the wall switch has multiple buttons 11, the key value information described above can represent different buttons 11 in the smart switch, and different buttons 11 can correspond to different relay channels 175 in the wall switch. If the wall switch has only one button 11, the key value information can also represent the switch information of the smart switch, and the switch information can be, for example, the ID of the smart switch; the function identifier can be corresponding to the switch information or to the information of a certain button 11.

[0295] In one specific embodiment, such as Figure 27 and Figure 28 As shown, the display screen 164 includes a ribbon cable 165, and the display screen 164 is electrically connected to the PCB board 16 via the ribbon cable 165. The button 11 is adapted to the position of the display screen 164, and the display screen 164 is configured to display the corresponding function of the button 11. The display screen 164 transmits data via the ribbon cable 165. A ribbon cable connector 1651 is provided at the end of the ribbon cable 165 away from the display screen 164. A ribbon cable connector 166 is soldered onto the PCB board 16, and the ribbon cable connector 1651 is snapped into the ribbon cable connector 166 to achieve an electrical connection between the display screen 164 and the PCB board 16. In another embodiment, the PCB board 16 is provided with data transmission contacts (not shown in the figure), and the ribbon cable 165 is glued to the data transmission contacts to achieve an electrical connection between the display screen 164 and the PCB board 16; or the ribbon cable 165 is soldered to the PCB board 16 (not shown in the figure) to achieve an electrical connection between the display screen 164 and the PCB board 16. The matching of the positions of the buttons 11 and the display screen 164 can be understood as the display screen 164 being positioned to correspond to the buttons 11, so that the position displayed on the display screen 164 corresponds to the corresponding button 11. For example, the buttons 11 are arranged horizontally side by side on the upper surface of the housing 14, and the screen is set as a long strip, arranged horizontally at the ends of the buttons 11, wherein the long side of the screen is in the same direction as the arrangement of the buttons 11, and the screen can display the function corresponding to the button 11 at the corresponding position at the end of each button 11. Alternatively, as shown in the figure, there are four buttons 11, arranged in pairs side by side on the upper surface of the housing 14, with the four buttons 11 located at the four corners of the upper surface of the housing 14. The display screen 164 is rectangular, arranged at the intersection of the four buttons 11, and the screen is divided into four areas, with each area corresponding to the corresponding position of the four buttons 11, and each area of ​​the screen can display the function of the corresponding button 11. The wireless communication module 13 is soldered to the PCB board 16 to realize the electrical connection between the display screen 164 and the wireless communication module 13. The wireless communication module 13 controls the display content of the display screen 164 according to the function of the button 11.

[0296] Furthermore, such as Figure 27As shown, the lower housing 142 includes a bottom housing 19 and an isolation cover 18. The isolation cover 18 covers the bottom housing 19 and forms a receiving cavity with the bottom housing 19. The PCB board 16 is accommodated inside the receiving cavity. A display screen mounting position 184 protrudes from the center of the isolation cover 18 toward the button 11. The display screen mounting position 184 is a channel-shaped structure that runs vertically through the bottom. The display screen 164 is fixedly mounted on the upper surface of the display screen mounting position 184. The ribbon cable 165 passes through the display screen mounting position 184 and is electrically connected to the PCB board 16. The display screen 164 is fixedly installed in the display screen mounting position 184. Specifically, the middle part of the isolation cover 18 extends upward to form a first side 1841, a second side 1842, a third side 1843, and a fourth side 1844 that surround each other to form the display screen mounting position 184. The display screen mounting position 184 has an opening at the upper end. The display screen 164 covers and is pasted on the upper surface of the display screen mounting position 184. The ribbon cable 165 of the display screen 164 passes through the display screen mounting position 184 and is connected to the PCB board 16.

[0297] like Figure 27 and Figure 28 As shown, the button 11 has a corresponding clearance 115 on the display screen 164, and the display screen 164 is enclosed within the clearance 115, with the upper surface of the display screen 164 flush with the upper surface of the button 11. The clearance 115 on the button 11 at the corresponding position on the display screen 164 can be understood as a through-hole. The buttons 11 are arranged in a series on the upper housing 141, with through-holes on the display screen 164 at corresponding positions for the display screen 164 to pass through. A gap exists between the clearance 115 and the display screen 164 to prevent interference between the button 11 and the display screen 164 during movement. The flush alignment of the upper surface of the display screen 164 with the upper surface of the button 11 can be understood as the height of the display mounting position 184 matching the height of the button 11, ensuring that the upper surfaces of the display screen 164 and the button 11 are on the same plane, improving aesthetics.

[0298] Furthermore, such as Figure 27 As shown, the upper housing 141 has a through hole for the display screen 164 at a corresponding position. The shape of the through hole is adapted to the display screen 164. After passing through the through hole, the display screen 164 is placed in the display screen clearance position 115. Since the display screen mounting position 184 protrudes upward from the isolation cover 18, the upper housing 141 located above the isolation cover 18 needs to have a through hole for the display screen 164 to pass through.

[0299] Furthermore, such as Figure 28As shown, the button 11 extends towards the upper housing 141 from the corresponding positions of the first side 1841 and the third side 1843 of the display mounting position 184, with the button latch 112 extending outwards. The first side 1841 and the third side 1843 are arranged opposite to each other. Specifically, taking the four-button 11 version of the switch structure as an example, each button 11 is provided with four button latches 112. The button latches 112 are provided at the three corners of each button 11 away from the display screen 164. Due to the display screen clearance 115, the corner closest to the display screen 164 has a rectangular notch. The button latches 112 are provided near the rectangular notch of the button 11, so that the four button latches 112 are located as close as possible to the corner of the button 11 to provide stable limiting for the button 11.

[0300] According to another aspect of the present invention, a wireless smart switch 102 is also provided. Unlike the wall smart switch 101 described above, the wireless smart switch 102 is battery-powered and communicatively connected to a receiver, indirectly controlling the operation of the controlled device through the receiver. In a specific embodiment, the receiver is the wall smart switch 101 described above. In use, the wireless smart switch 102 triggers the detection element 12 in response to the user's operation, thereby sending a wireless message to the receiver. The receiver controls the operation of the controlled device according to the content of the wireless message, thus realizing the indirect control of the controlled device by the wireless smart switch 102. The controlled device can be a traditional electrical appliance such as a light or fan, which can be controlled to turn on and off by controlling the power supply; or it can be a smart device such as an air conditioner, television, robot vacuum cleaner, or smart curtain motor, which is controlled by the receiver issuing control commands to the controlled device.

[0301] Specifically, such as Figure 57 and Figure 58 As shown, the wireless smart switch 102 provided by the present invention includes: a housing 14, at least one button 11, a detection element 12, a reset part 15, and a wireless communication module 13. The button 11 is disposed on the housing 14, and at least a portion of the button 11 can respond to a control force to undergo a pressing movement, thereby generating displacement, such that the button 11 passes through at least a first pressing position and a second pressing position in sequence, and generates a reaction force. The detection element 12 can be triggered based on the displacement and generates a first rebound force to resist the displacement. The reset part 15 is configured to support the button 11 to deform directly or indirectly in response to the pressing movement, and generate a reset force to overcome the deformation. The wireless communication module 13 is communicatively connected to the detection element 12 to receive a corresponding trigger signal and send wireless messages to the outside based on the trigger signal.

[0302] The detection element 12 and the reset part 15 cooperate to ensure that: when the button 11 moves to the first pressing position, the reaction force is F1, and when the button 11 moves from the first pressing position to the second pressing position, the reaction force changes from F1 to F2; wherein, F2 < F1 < 400g; the displacement S1 of the button 11 at the first pressing position and the displacement S2 at the second pressing position satisfy the relationship: S2 - S1 ≤ 2mm.

[0303] The wireless communication module 13 sending wireless messages based on the trigger signal can be understood as follows: the wireless communication module 13 is electrically connected to the detection element 12. When the detection element 12 is triggered, a corresponding trigger signal is generated. When the wireless communication module 13 detects the trigger signal, it sends the corresponding wireless message. Other technical details and principles have been explained in detail above and will not be repeated here.

[0304] like Figure 57 and Figure 58 As shown, the wireless smart switch 102 provided by this invention shares many similarities with the wall smart switch 101 described above, such as the structure of the button 11, reset part 15, upper housing 141, and light diffuser 183. The technical details and principles are explained in detail above and will not be repeated here. The differences are: 1. The wireless smart switch 102 does not have a power board 17 or related electronic components; the PCB board 16 is powered by a battery. 2. The bottom housing 19 of the wireless smart switch 102 differs from that of the wall smart switch 101, specifically including different connection structures between the PCB board 16 and the bottom housing 19, different structures of the magnetic component 1422, different connection structures between the magnetic component 1422 and the bottom housing 19, and the absence of heat dissipation holes 1427 in the bottom housing 19. 3. The isolation cover 18 has through holes for battery installation and removal, indicating a structural difference. The following section will provide a detailed explanation of the distinguishing technical features between the wireless smart switch 102 and the wall smart switch 101.

[0305] First, the magnetic structure of the wireless smart switch 102 differs from that of the wall smart switch 101. Specifically, as follows: Figure 58 and Figure 59As shown, in some embodiments, the lower housing 142 is provided with a magnetic suction fixing part 42 at a corresponding position of the magnet mounting groove 14161, and the magnetic suction fixing part 42 is fixedly connected to the magnetic suction member 1422. The magnetic suction fixing part 42 can be understood as a structure capable of fixing and installing the magnetic suction member 1422. It is fixedly connected to or integrally formed in the lower housing 142. The magnetic suction member 1422 and the magnetic suction fixing part 42 can be fixedly connected by snap-fit, adhesive, clamping, screw fastening, or other feasible methods. A magnet 1416 is fixedly installed in the magnet mounting groove 14161 of the upper housing 141. The structural details of this magnet have been described in detail above and will not be repeated here. The upper housing 141 is attracted to the magnetic suction member 1422 of the lower housing 142 by the magnet 1416, thereby achieving a magnetically detachable connection between the upper housing 141 and the lower housing 142. The lower housing 142 is provided with a first positioning part 1424, which cooperates with the second positioning part 1418 of the upper housing 141 to position the upper housing 141 by the lower housing 142. This technical detail has been described in detail above and will not be repeated here. In a specific embodiment, the magnet 1416 fixing part corresponds to the position of the magnet 1416 described above. The lower housing 142 includes a bottom housing 19 and an isolation cover 18 (this technical detail has been described in detail above). There are two magnetic attraction fixing parts 42, located at the left and right ends of the bottom housing 19, to increase the stability of the magnetic attraction connection.

[0306] Furthermore, such as Figure 58 and Figure 59 As shown, the magnetic fastener fixing part 42 has a magnetic fastener through hole 421. The shape of the magnetic fastener through hole 421 is adapted to the magnet mounting groove 14161, so that the lower surface of the magnet mounting groove 14161 passes through the magnetic fastener through hole 421 and fits against the upper surface of the magnetic fastener 1422. The shape of the magnetic fastener through hole 421 adapting to the magnet mounting groove 14161 can be understood as the magnetic fastener through hole 421 being slightly larger than the lower surface of the magnet mounting groove 14161, allowing the magnet mounting groove 14161 to pass through the magnetic fastener through hole 421. The advantage of this design is that it reduces the distance between the magnet 1416 and the magnetic fastener 1422; furthermore, the wireless smart switch 102 of the present invention can adhere to an iron surface, increasing the magnetic attraction between the magnet 1416 and the magnetic fastener 1422, allowing the magnet 1416 to attract the iron mounting surface through the magnetic fastener 1422, preventing the switch from falling off due to insufficient magnetic attraction. Furthermore, such as Figure 57 and Figure 59 As shown, an anti-slip sticker 43 is pasted on the lower surface of the magnetic fixing part 42 at the corresponding position of the magnetic component 1422. The upper surface of the anti-slip sticker is adhesive and the lower surface is anti-slip. It can prevent the magnetic component 1422 from falling down out of the magnetic fixing part 42 and also play an anti-slip role. When the switch is magnetically attracted to an iron mounting surface, the anti-slip sticker 43 can prevent the switch from sliding.

[0307] In another embodiment, such as Figure 60 As shown, the magnetic chuck fixing part 42 has a magnetic chuck through hole 421. At least a portion of the upper surface of the magnetic chuck 1422 passes through the magnetic chuck through hole 421 and is flush with the upper surface of the magnetic chuck fixing part 42. When the upper housing 141 covers the lower housing 142, at least a portion of the upper surface of the magnetic chuck 1422 is in contact with the lower surface of the magnet mounting groove 14161. The fact that at least a portion of the upper surface of the magnetic chuck 1422 is flush with the upper surface of the magnetic chuck fixing part 42 can be understood as follows: Figure 60 As shown, with the direction from the bottom shell 19 to the button 11 as the upward direction, the shape of the magnetic suction through hole 421 is consistent with the upper shape of the magnetic suction 1422. After the upper part of the magnetic suction 1422 passes through the magnetic suction through hole 421, its upper surface is on the same plane as the upper surface of the magnetic suction fixing part 42. This allows the lower surface of the magnet mounting groove 14161 to simultaneously fit against both the magnetic suction 1422 and the magnetic suction fixing part 42. This shortens the distance between the magnet 1416 and the magnetic suction 1422 to enhance the magnetic attraction force, and also ensures that the magnet mounting groove 14161 is supported by the magnetic suction fixing part 42, preventing the upper shell 141 from tilting when the button 11 is pressed. In other embodiments, the upper surface of the magnetic suction 1422 can be slightly recessed below the upper surface of the magnetic suction fixing part 42 to ensure that the magnet mounting groove 14161 is supported by the bottom shell 19.

[0308] Furthermore, such as Figure 60 As shown, the magnetic attractor 1422 includes a fitting portion 14223 and a base portion 14224 integrally formed with the fitting portion 14223. The fitting portion 14223 passes through the magnetic attractor through hole 421 and fits against the lower surface of the magnet mounting groove 14161. The size of the base portion 14224 is larger than the size of the fitting portion 14223, so that a first step is formed between the fitting portion 14223 and the base portion 14224. The magnetic attractor through hole 421 includes a first through hole that mates with the fitting portion 14223 and a second through hole that mates with the base portion 14224. The size of the second through hole is larger than the size of the first through hole, so that a second step is formed between the first through hole and the second through hole. The second step abuts against the first step, thereby restricting the vertical upward displacement of the magnetic attractor 1422. The fitting portion 14223 is interference-fitted with the first through hole, such that the fitting portion 14223 passes through the first through hole and is clamped in the first through hole.

[0309] Furthermore, the magnetic suction fixing part 42 is configured as a downward-facing groove. The magnetic suction fixing part 42 is interference-fitted with the magnetic suction part 1422, so that the magnetic suction part 1422 is placed below the magnetic suction fixing part 42 and clamped therein. Furthermore, an anti-slip sticker 43 (not shown in the figure) is pasted on the lower surface of the magnetic suction fixing part 42 at a corresponding position on the magnetic suction part 1422. The upper surface of the anti-slip sticker is adhesive, and the lower surface has anti-slip properties, which not only prevents the magnetic suction part 1422 from falling out of the magnetic suction fixing part 42 but also provides an anti-slip function. Both the fitting part 14223 and the base part 14224 of the magnetic suction part 1422 are racetrack-shaped, which facilitates the insertion of the magnetic suction part 1422 into the magnetic suction fixing part 42.

[0310] In some embodiments, such as Figures 61-62 As shown, the projection of the magnetic fixing part 42 onto the bottom surface of the lower housing 142 is designated as the first projection pattern. A magnetic protrusion 44 protrudes from the magnetic fixing part 42 toward the magnet mounting groove 14161. The projection of the magnetic protrusion 44 onto the bottom surface of the lower housing 142 is designated as the second projection pattern, which covers the first projection pattern. A hollow through-hole 14162 is formed at the bottom of the magnet mounting groove 14161 toward the magnetic protrusion 44. The projection of the hollow through-hole 14162 onto the bottom of the lower housing 142 is designated as the third projection pattern, which covers the second projection pattern. The height of the magnetic protrusion 44 is greater than or equal to the thickness of the bottom of the magnet mounting groove 14161. The magnetic protrusion 44 passes through the hollow through-hole 14162 and adheres to the lower surface of the magnet 1416. Wherein, as... Figure 62 As shown, the magnetic suction protrusion 44 can be understood as follows: since the bottom shell 19 is relatively thin, similar in thickness to the magnetic suction component 1422, a groove is formed on the lower surface of the magnetic suction component fixing part 42 to accommodate the magnetic suction component 1422. Correspondingly, the magnetic suction component fixing part 42 has a magnetic suction protrusion 44 above the magnetic suction component 1422 to enhance the wall thickness of the magnetic suction component fixing part 42 above the magnetic suction component 1422 and increase the strength of the magnetic suction component fixing part 42. In addition, since the projected area of ​​the hollow through hole 14162 is larger than the projected area of ​​the magnetic suction protrusion 44, the magnetic suction protrusion 44 can pass through the hollow through hole 14162. The thickness of the magnetic suction protrusion 44 is consistent with the thickness of the bottom wall of the magnet mounting groove 14161, so that the lower surface of the magnet 1416 can fit against the upper surface of the magnetic suction protrusion 44.

[0311] In another embodiment, such as Figure 63 and Figure 64As shown, the magnetic suction member fixing part 42 has at least one magnetic suction member fixing through hole 422. A portion of the magnetic suction member 1422 has at least one magnetic suction member recess 14225 recessed downwards. The size of the magnetic suction member recess 14225 matches the size of the magnetic suction member fixing through hole 422, such that the magnetic suction member recess 14225 is placed in the magnetic suction member through hole 421, and the other parts of the magnetic suction member 1422, except for the magnetic suction member recess 14225, overlap the upper surface of the magnetic suction member fixing part 42. The magnetic suction member 1422 is bonded and fixed to the magnetic suction member fixing part 42. The size of the magnetic suction member recess 14225 matches the size of the magnetic suction member fixing through hole 422. This can be understood as follows: the size of the magnetic suction fixing through hole 422 is larger than the size of the magnetic suction recess 14225, so that the magnetic suction recess 14225 can sink into the magnetic suction fixing through hole 422. In a specific embodiment, two magnetic suction fixing through holes 422 are respectively provided at both ends of the bottom shell 19, and a magnetic suction 1422 is respectively provided at both ends of the bottom shell 19. Each magnetic suction 1422 includes two magnetic suction recesses 14225, which are respectively placed in the magnetic suction fixing through hole 422. The part of the magnetic suction 1422 other than the magnetic suction recess 14225 overlaps the upper surface of the magnetic suction fixing part 42, that is, part of the lower surface of the magnetic suction 1422 is attached to part of the upper surface of the bottom shell 19 and is fixed by adhesive.

[0312] like Figure 64 As shown, the depth of the magnetic suction recess 14225 is adapted to the thickness of the magnetic suction 1422, so that the upper surface of the magnetic suction recess 14225 is flush with the upper surface of the magnetic suction fixing part 42. The position of the magnetic suction recess 14225 corresponds to the position of the magnet mounting groove 14161, and the length of the magnetic suction recess 14225 is greater than the length of the lower surface of the magnet mounting groove 14161, so that the lower surface of the magnet mounting groove 14161 is in contact with the upper surface of the magnetic suction recess 14225.

[0313] In a preferred embodiment, the magnetic components 1422 are all stamped parts, which saves manufacturing costs.

[0314] In another embodiment, a light-diffusing sheet 1881 (not shown in the figure) is laid on the side of the button 11 facing the housing 14. The light-diffusing sheet 1881 is disposed between the LED lamp 163 and the light guide portion 114. The light emitted by the LED lamp 163 is diffused by the light-diffusing sheet 1881 and then projected onto the light guide portion 114. The light-diffusing sheet 1881 can be understood as a sheet-like component with a light-diffusing function, such as an opaque plastic sheet or a frosted glass sheet. In this embodiment, the light-diffusing sheet 1881 is made of a translucent white plastic sheet and is directly pasted onto the lower surface of the button 11, eliminating the need for a light-diffusing cover 183, saving costs, and allowing the switch to be made thinner.

[0315] Furthermore, the side of the button 11 facing the housing 14 is designated as a first surface. A light-transmitting sheet 1883 (not shown in the figure) is laid on the first surface at a corresponding position of the light guide portion 114. The light-transmitting sheet 1883 is configured as a rainbow film, capable of reflecting natural light into colored light. The projection of the light-transmitting sheet 1883 onto the first surface covers the projection of the light guide portion 114 onto the first surface. The rainbow film, also known as a seven-color film or iridescent film, is a plastic composite film made by melting and extruding two or more resins with different refractive indices and stacking them in layers at intervals, up to 100 layers or more, with each layer only a few hundred nanometers thick. The rainbow film is a transparent film whose surface reflects a seven-color luster under light. In this embodiment, the rainbow film is pasted onto the first surface of the button 11, that is, the rainbow film is placed below the light guide portion 114 of the button 11, so that when viewed from the top surface of the button 11, the light guide portion 114 of the button 11 reflects a seven-color luster, improving the aesthetics of the button 11.

[0316] It should be noted that, in this invention, the wireless communication module and the detection device can be electrically connected via a self-generating module or via a battery.

[0317] For details, please refer to Figure 57In one embodiment of the present invention, the wireless smart switch 102 further includes a power module 21, which includes at least one button battery 211 and a PCB board 16. The PCB board 16 is electrically connected to the button battery 211. The PCB board 16 is provided with the wireless communication module 13 and the detection element 12 for the wireless communication module 13 to be electrically connected to the detection element 12. Thus, the wireless communication module 13 and the detection element 12 are integrated on the PCB board 16, and the button battery 211 provides power to the PCB board 16, thereby completing the process of the detection element 12 sending a trigger signal to the wireless communication module 13, the wireless communication module 13 receiving the trigger signal from the detection element 12, and sending a wireless message to the outside based on the trigger signal. More specifically, in one embodiment of the present invention, the button battery 211 is of model CR2032. The CR2032 button battery 211 has high specific energy, long storage life, low self-discharge, long discharge time, and stable discharge voltage. Its operating temperature range is -20 to 70°C, making it very suitable for the wireless smart switch 102 product. In addition, the CR2032 button battery 211 is high-energy and environmentally friendly, free of lead, cadmium, and mercury, and complies with EU environmental regulations, meeting the modern green environmental protection concept.

[0318] It should be noted that the number of button batteries 211 is not limited; one button battery 211 can be used, or two can be used, etc. For details, please refer to [link / reference needed]. Figure 57 and Figure 58 In one embodiment of the present invention, two button batteries 211 are provided.

[0319] Furthermore, based on the above embodiment where "the housing 14 includes an upper housing 141 and a lower housing 142, the upper housing 141 covers the lower housing 142 and is detachably connected to the lower housing 142, the button 11 is located on the upper housing 141; and the PCB board 16 is located on the lower housing 142", the lower housing 142 has at least one battery accommodating cavity 22, the battery accommodating cavity 22 has an opening facing the upper housing 141, and the battery accommodating cavity 22 is used to accommodate the button battery 211. That is to say, the power module 21, the detection element 12, and the wireless communication module 13 are all located on the lower housing 142, thereby reducing the cost of replacing the upper housing 141.

[0320] It should be noted that the number of battery accommodating cavities 22 corresponds to the number of button batteries 211. For details, please refer to [link / reference needed]. Figure 57 and Figure 58 In one embodiment of the present invention, two button batteries 211 are provided, and correspondingly, two battery accommodating cavities 22 are also provided.

[0321] Furthermore, based on the aforementioned embodiment where "the lower housing 142 includes a bottom housing 19 and an isolation cover 18, the isolation cover 18 covers the bottom housing 19 and forms a receiving cavity 191 with the bottom housing 19, and the PCB board 16 is accommodated inside the receiving cavity 191", the button battery 211 is also disposed inside the receiving cavity 191. Thus, the battery receiving cavity 22 is formed in the bottom housing 19 and / or the isolation cover 18. That is to say, the battery receiving cavity 22 can be formed in the bottom housing 19 or in the isolation cover 18. Of course, a part of the battery receiving cavity 22 can also be formed in the bottom housing 19 and another part in the isolation cover 18, thereby reducing the thickness of the lower housing 142 and making the wireless smart switch 102 thinner and lighter, easier to carry and transport. More specifically, a portion of the battery accommodating cavity 22 formed in the bottom housing 19 may be formed on the bottom wall of the bottom housing 19, that is, on the side wall of the bottom housing 19 away from the upper housing 141. Alternatively, it may be formed on the PCB board 16 located within the bottom housing 19, thereby reducing the thickness of the lower housing 142. For details, please refer to... Figure 57 In one embodiment of the present invention, a portion of the battery accommodating cavity 22 is formed in the isolation cover 18, and another portion is formed in the PCB board 16.

[0322] It should be noted that the connection method between the isolation cover 18 and the bottom shell 19 is not limited. Specifically, in some embodiments of the present invention, the isolation cover 18 and the bottom shell 19 are detachably connected. Compared with the non-detachable connection method, when the components in the receiving cavity 191 have problems, maintenance personnel can directly disassemble the isolation cover 18 and the bottom shell 19, which is very convenient for repairing or replacing faulty components, and the product has high economic efficiency. Furthermore, in some embodiments of the present invention, the isolation cover 18 and the bottom shell 19 are snap-fit ​​connected; in other embodiments of the present invention, the isolation cover 18 and the bottom shell 19 are threaded connected. This connection method can ensure the stable connection between the isolation cover 18 and the bottom shell 19, and its operation is simple and quick, and the cost is low.

[0323] Of course, the connection method between the PCB board 16 and the bottom shell 19 is not limited. Specifically, the PCB board 16 and the bottom shell 19 can be detachably connected, which is very convenient compared to some non-detachable connection methods. Furthermore, in some embodiments of the present invention, the PCB board 16 and the bottom shell 19 are snapped together. This connection method is simple to operate and does not require tools to assist in installation or disassembly, resulting in high assembly efficiency.

[0324] It should be noted that in this invention, the above two technical features can be configured selectively or simultaneously. For details, please refer to [link / reference needed]. Figure 57 , Figure 58 and Figure 79 In some embodiments of the present invention, the above two technical features are provided simultaneously, that is, the isolation cover 18 is threadedly connected to the bottom shell 19, and the PCB board 16 is snapped into the bottom shell 19. In other words, the connection between the bottom shell 19 and the isolation cover 18 and the PCB board 16 is a detachable connection, which facilitates installation and disassembly and improves the economic efficiency of product use.

[0325] For further details, please refer to Figure 58 , Figures 77 to 80 In one embodiment of the present invention, the bottom wall of the receiving cavity 191 of the bottom shell 19 is provided with a plurality of mounting posts 192 spaced apart along its circumference. Each mounting post 192 has a first mounting hole 193 with an opening facing away from the bottom shell 19. The isolation cover 18 has a plurality of second mounting holes 18a corresponding to the plurality of first mounting holes 193. Each second mounting hole 18a and its corresponding first mounting hole 193 are sequentially used for a screw to be inserted, so that the isolation cover 18 is threadedly connected to the bottom shell 19. The PCB board 16 has a plurality of locking holes corresponding to the plurality of mounting posts 192. Each locking hole is used for its corresponding mounting post 192 to be inserted, so that the PCB board 16 and the bottom shell 19 are locked together by the plurality of mounting posts 192. With this configuration, the bottom shell 19 achieves both threaded connection with the isolation cover 18 and locking connection with the PCB board 16 through the plurality of mounting posts 192, which greatly simplifies the structure and saves space. More specifically, the plurality of mounting posts 192 abut against the sidewall of the receiving cavity 191. To this end, a plurality of locking holes are formed on the periphery of the PCB board 16, and each locking hole is a semi-circular hole so that when the PCB board 16 is installed, the inner sidewall of each locking hole is adapted to abut against a portion of the outer peripheral wall of the corresponding mounting post 192.

[0326] For further details, please refer to Figure 57 , Figure 58 , Figure 77 and Figure 78In one embodiment of the present invention, the isolation cover 18 includes an isolation cover body and a plurality of mounting portions disposed around the periphery of the isolation cover body. The plurality of mounting portions are used to be threadedly connected to a plurality of mounting posts 192 in a one-to-one correspondence. Each mounting portion protrudes from the periphery of the end of the isolation cover body away from the bottom shell 19. Thus, by setting the size, after the isolation cover 18 is threadedly connected to the plurality of mounting posts 192, a portion of the isolation cover body is located in the receiving cavity 191 of the bottom shell 19 and pressed onto the PCB board 16, so as to fix the PCB board 16 together with the bottom shell 19, thereby improving the installation stability of the PCB board 16 and reducing the thickness of the lower shell 142.

[0327] Specifically, in order to ensure that the button battery 211 is securely installed, the lower housing 142 is provided with a battery fixing structure 23 for detachably installing the button battery 211 in the battery receiving cavity 22. The battery fixing structure 23 is not only used to fix the button battery 211, but also facilitates the installation or removal of the battery, so as to facilitate the replacement of old and new batteries, extend the service life of the wireless smart switch 102, and improve its practicality.

[0328] It should be noted that in some embodiments of the present invention, the button battery 211 can be directly snapped into the battery housing 22. However, to prevent the button battery 211 from moving along with the wireless smart switch 102 when it is activated, thus affecting the power supply effect or even causing it to fall out of the battery housing 22, and because the sidewall of the battery housing 22 defines the button battery 211 in a direction parallel to the bottom wall of the battery housing 22, the battery fixing structure 23 further includes a movable latch 231. The movable latch 231 includes a latch attached to the lower housing 14. The device comprises a connecting portion 2311 and a fastening portion 2312 connected to the connecting portion 2311. The fastening portion 2312 is located at one end of the connecting portion 2311 near the battery housing cavity 22. The fastening portion 2312 can be close to or away from the battery housing cavity 22. When close to the battery housing cavity 22, it is used to fix the button battery 211 together with the bottom wall of the battery housing cavity 22. Thus, by providing the movable buckle 231, the button battery 21 can be fixed and limited together with the bottom wall of the battery housing cavity 22 in a direction perpendicular to the bottom wall of the battery housing cavity 22. 1. To prevent the button battery 211 from falling out of the battery housing cavity 22, thereby improving the installation stability of the button battery 211; specifically, when installing or removing the button battery 211, the engaging portion 2312 of the movable latch 231 moves away from the battery housing cavity 22, and moves beyond the range of motion for installing or removing the button battery 211, thereby ensuring that the engaging portion 2312 of the movable latch 231 does not interfere with the button battery 211 during the installation or removal process, allowing the button battery 211 to be smoothly placed... The button battery 211 is placed or removed into the battery housing cavity 22. During the installation of the button battery 211, after the button battery 211 is placed into the battery housing cavity 22, the engaging part 2312 of the movable buckle 231 moves towards the battery housing cavity 22 until it abuts against the upper wall of the button battery 211, thereby fixing the button battery 211 together with the bottom wall of the battery housing cavity 22, completing the installation and fixing of the button battery 211, and preventing the button battery 211 from falling out of the battery housing cavity 22 when the wireless smart switch 102 is activated.

[0329] It should also be noted that, in this invention, the movement of the engaging portion 2312 of the movable buckle 231 towards or away from the battery accommodating cavity 22 is not restricted. It can be that the movable buckle 231 moves relative to the lower housing 142, or that the engaging portion 2312 of the movable buckle 231 rotates relative to the connecting portion 2311. Of course, both of the above methods can be used simultaneously, that is, while the movable buckle 231 moves relative to the battery accommodating cavity 22, its engaging portion 2312 is also subjected to force to rotate relative to its connecting portion 2311, thereby quickly completing the installation or removal of the button battery 211.

[0330] For further details, please refer to Figure 77 and Figure 78 In some embodiments of the present invention, by setting the material of the connection portion 2311 between the movable buckle 231 and the lower housing 142, the movable buckle 231 can move relative to the lower housing 142. Specifically, the lower housing 142 has a first clearance hole 18e extending through it in a direction perpendicular to the bottom wall of the battery accommodating cavity 22. There is an elastic wall 221 between the first clearance hole 18e and the battery accommodating cavity 22. The elastic wall 221 can be elastically deformed in a direction toward or away from the first clearance hole 18e under force. The movable buckle 231 is disposed on the elastic wall 221 so as to move closer to or away from the battery accommodating cavity 22 during the elastic deformation of the elastic wall 221. The sidewall of the cavity 22 includes the elastic wall 221; that is, through the movable space provided by the first clearance hole 18e, the elastic arm, due to its material properties, can undergo elastic deformation in the direction toward or away from the first clearance hole 18e under force. Thus, when the movable buckle 231 is subjected to force, the elastic arm undergoes elastic deformation under the force transmitted from the movable buckle 231, thereby causing the movable buckle 231 to move as a whole away from or toward the battery receiving cavity 22, so that the fastening part 2312 moves away from or toward the battery receiving cavity 22, realizing the installation or removal of the button battery 211; more specifically, the material of the elastic wall 221 is plastic, etc., which is low in cost and simple to process.

[0331] It should be noted that in this invention, the extending direction of the first clearance hole 18e is not limited. For details, please refer to [link / reference needed]. Figure 77 and Figure 78 In some embodiments of the present invention, the first clearance hole 18e extends circumferentially along the battery accommodating cavity 22, so that the deformation stress of the elastic wall 221 is uniformly distributed.

[0332] For further details, please refer to Figure 77In one embodiment of the present invention, the lower housing 142 is provided with two compensation holes 18b in a direction perpendicular to the bottom wall of the battery accommodating cavity 22. The two compensation holes 18b are respectively located on both sides of the elastic wall 221, and each compensation hole 18b communicates with the battery accommodating cavity 22. When the movable buckle 231 is subjected to force away from the battery accommodating cavity 22, the side wall of each compensation hole 18b near the elastic wall 221 undergoes elastic deformation in the direction toward the movable buckle 231, compensating for the elastic wall 221 used for connection. The elastic deformation of a portion of the movable buckle 231 allows the elastic wall 221 to be subjected to force as a whole when the movable buckle 231 moves away from the battery accommodating cavity 22. This prevents the deformation stress of the elastic wall 221 from concentrating at the connection between the elastic wall 221 and the movable buckle 231, thus avoiding breakage at the connection between the elastic wall 221 and the movable buckle 231. Furthermore, the provision of the compensation hole 18b makes the elastic arm more easily deformable, thereby making it more convenient to install or remove the button battery 211.

[0333] Specifically, in order to further reduce the thickness of the lower housing 142, please refer to... Figure 77 In one embodiment of the present invention, the elastic wall 221 is recessed to a certain preset depth in the direction toward the bottom wall of the battery accommodating cavity 22, and the first clearance hole 18e communicates with the battery accommodating cavity 22, which reduces the height of the movable buckle 231 protruding from the lower housing 142, which is beneficial to the thin and light design of the wireless smart switch 102; at the same time, the elastic wall 221 is thinner due to its recess, so it is easier to undergo elastic deformation when subjected to force, which facilitates operation.

[0334] For details, please refer to Figure 78 In some embodiments of the present invention, one end of the first clearance hole 18e is configured as a connecting end, which is connected to the battery accommodating cavity 22; that is, the connecting end is located between one end of the elastic wall 221 and the side wall of the battery accommodating cavity 22. Therefore, during the movement of the movable buckle 231 towards or away from the battery accommodating cavity 22, the force exerted by the side wall of the battery accommodating cavity 22 on the elastic wall 221 is reduced, and the elastic wall 221 is more likely to undergo elastic deformation, which facilitates operation.

[0335] Furthermore, the position of the movable latch 231 on the elastic wall 221 is not restricted. However, since the force exerted on the elastic wall 221 by the side wall of the battery accommodating cavity 22 gradually decreases from the end of the elastic wall 221 away from the connecting end to the end of the elastic wall 221 closer to the connecting end, the end of the elastic wall 221 closer to the connecting end can move relative to the side wall of the battery accommodating cavity 22. Therefore, please refer to... Figure 78In some embodiments of the present invention, the movable latch 231 is disposed close to the connecting end. Compared to being disposed away from the connecting end, the movable latch 231 has a larger range of motion when disposed close to the connecting end, and is more easily activated by force, thereby making the installation and removal of the button battery 211 more convenient. More specifically, the movable latch 231 is disposed at one end of the elastic wall 221 close to the connecting end, improving the efficiency of installing and removing the button battery 211.

[0336] Please see Figure 77 and Figure 78 In some embodiments of the present invention, when the movable buckle 231 moves, its fastening part 2312 can be rotated relative to its connecting part 2311 under force. Specifically, the movable buckle 231 is configured as an elastic buckle. According to the material characteristics of the movable buckle 231, when subjected to force, its fastening part 2312 can be elastically deformed and rotate relative to its connecting part 2311. More specifically, the material of the movable buckle 231 is plastic or rubber, etc., which is low in cost and easy to process.

[0337] Of course, in other embodiments of the present invention, the engagement portion 2312 of the movable buckle 231 can be rotated relative to the connecting portion 2311 to allow the engagement portion 2312 to move closer to or further away from the battery accommodating cavity 22. Specifically, the portion of the battery accommodating cavity 22 away from the opening end face of the bottom shell 19 is recessed to form a relief groove. The movable buckle 231 is disposed on the bottom wall of the relief groove, and the movable buckle 231 and the side wall of the relief groove away from the battery accommodating cavity 22 are spaced apart to form a first relief space. The first relief space is used to allow the engagement portion 2312 to move when the engagement portion 2312 of the movable buckle 231 moves away from the battery accommodating cavity 22. The first clearance space is configured to provide rotation space for the latching part 2312 of the movable buckle 231, ensuring that the latching part 2312 has sufficient space to rotate to avoid the button battery 211 during the installation or removal of the button battery 211, and does not interfere with the button battery 211, thereby ensuring the smooth installation and removal of the button battery 211. In addition, the movable buckle 231 is located in the clearance groove, so that the movable buckle 231 is flush with, lower than or slightly higher than the opening end face of the battery receiving cavity 22. Compared with the movable buckle 231 being directly located at the opening end of the battery receiving cavity 22, it can save space and is conducive to the thin and light design of the wireless smart switch 102.

[0338] Specifically, based on the above embodiment where "the lower housing 142 includes a bottom housing 19 and an isolation cover 18, the isolation cover 18 covers the bottom housing 19 and forms a receiving cavity 191 with the bottom housing 19, and the PCB board 16 is accommodated inside the receiving cavity 191", the movable buckle 231 is provided on the bottom housing 19 or the isolation cover 18, and the setting position of the movable buckle 231 is determined according to the setting position of the battery receiving cavity 22.

[0339] Specifically, when the battery accommodating cavity 22 is formed only in the isolation cover 18, the isolation cover 18 has a first accommodating through hole 222, the battery accommodating cavity 22 includes the first accommodating through hole 222, and the movable buckle 231 is disposed on the isolation cover 18 or the PCB board 16; when the battery accommodating cavity 22 is formed only in the PCB board 16, the PCB board 16 has a second accommodating through hole 223, the battery accommodating cavity 22 includes the second accommodating through hole 223, and the movable buckle 231 is disposed on the bottom shell 19, the... The PCB board 16 or the isolation cover 18; when a part of the battery accommodating cavity 22 is formed on the isolation cover 18 and another part is formed on the PCB board 16, the isolation cover 18 has a first accommodating through hole 222, the PCB board 16 has a second accommodating through hole 223, the first accommodating through hole 222 and the second accommodating through hole 223 are connected, the battery accommodating cavity 22 includes the first accommodating through hole 222 and the second accommodating through hole 223, and the movable buckle 231 is provided on the bottom shell 19 or the isolation cover 18.

[0340] For more details, please see Figures 1 to 3 In one embodiment of the present invention, in order to further reduce the thickness of the lower housing 142 and achieve a thinner and lighter design for the wireless smart switch 102, a portion of the battery accommodating cavity 22 is formed in the isolation cover 18 and another portion is formed in the bottom housing 19. Specifically, the isolation cover 18 has a first accommodating through-hole 222, and the PCB board 16 has a second accommodating through-hole 223. The first accommodating through-hole 222 and the second accommodating through-hole 223 are connected. The battery accommodating cavity 22 includes the first... The movable latch 231 is located on the bottom shell 19 or the isolation cover 18, and the second accommodating through hole 222 and the second accommodating through hole 223 are respectively located thereon. The volume of the movable latch 231 varies depending on its location. When the movable latch 231 is located on the isolation cover 18, its length is shorter than when it is located on the bottom shell 19, making it less prone to breakage when the latching part 2312 rotates, and also occupying less space. For more details, please refer to... Figure 57 and Figure 77In one embodiment of the present invention, the movable buckle 231 is disposed on the isolation cover 18 and on the side wall of the first accommodating through hole 222. The movable buckle 231 is movable relative to the lower housing 142, and the fastening part 2312 of the movable buckle 231 is rotatable relative to the connecting part 2311. The side wall of the first accommodating through hole 222 includes the elastic wall 221, and the elastic wall 221 is the bottom wall of the clearance groove.

[0341] To further improve the installation stability of the button battery 211, the battery fixing structure 23 also includes a limiting buckle 232. The limiting buckle 232 is disposed on the side wall or opening end of the battery receiving cavity 22 and is disposed opposite to the movable buckle 231. It is used to limit the button battery 211 in a direction perpendicular to the bottom wall of the battery receiving cavity 22. In this way, by setting the limiting buckle 232 and the movable buckle 231 to cooperate in fixing the button battery 211, the button battery 211 is prevented from falling out of the battery receiving cavity 22 during the operation of the wireless smart switch 102.

[0342] It should be noted that in this invention, the number of movable buckles 231 is not limited; there can be one, two, three, etc. For details, please refer to [link / reference needed]. Figures 1 to 3 In one embodiment of the present invention, based on the above embodiment in which "the battery fixing structure 23 further includes a limiting buckle 232, the limiting buckle 232 is disposed on the side wall or opening end of the battery accommodating cavity 22 and is disposed opposite to the movable buckle 231, for limiting the button battery 211 in a direction perpendicular to the bottom wall of the battery accommodating cavity 22", only one movable buckle 231 is required. This ensures the installation stability of the button battery 211, and the operator only needs to operate one movable buckle 231 to install or remove the button battery 211, which is simple and convenient.

[0343] Specifically, to facilitate the operation of the movable buckle 231, the movable buckle 231 also has a gripping part 2313. The gripping part 2313 is located on the side of the connecting part 2311 away from the battery housing 22 in a direction perpendicular to the bottom wall of the battery housing cavity 22. A second guide slope is provided between the gripping part 2313 and the fastening part 2312. The gripping part 2313 greatly facilitates the operator to apply force to the movable buckle 231, while the second guide slope guides the button battery 211. The button battery 211 can slide directly into the battery housing cavity 22 along the second guide slope, making the installation of the button battery 211 simpler and more convenient.

[0344] Specifically, to ensure stable installation of the button battery 211, the gap between the button battery 211 and the battery housing 22 is generally small. This results in insufficient space for operators to quickly and directly remove the button battery 211 from the battery housing 22, thus affecting the disassembly efficiency of the button battery 211. Therefore, in some embodiments of the present invention, an elastic member 24 is provided in the battery housing 22. The elastic member 24 has a natural state and a pressed state under the pressure of the button battery 211, for use in... When the engaging portion 2312 of the movable latch 231 moves away from the button battery 211, the elastic member 24 returns from the pressed state to the natural state and acts on the button battery 211 to eject part of the button battery 211 from the battery receiving cavity 22. Thus, by providing the elastic member 24, when the button battery 211 is not restricted by the movable latch 231, part of the button battery 211 is ejected from the battery receiving cavity 22 by the elastic force of the elastic member 24, improving the convenience of removing the button battery 211.

[0345] It should be noted that, based on the above embodiment where "the battery fixing structure 23 further includes a limiting buckle 232, which is disposed on the side wall or opening end of the battery accommodating cavity 22 and is disposed opposite to the movable buckle 231 to limit the button battery 211 in a direction perpendicular to the bottom wall of the battery accommodating cavity 22", the elastic member 24 is disposed close to the movable buckle 231. Thus, when the fastening part 2312 of the movable buckle 231 is away from the button battery 211, the force exerted by the limiting buckle 232 on the part of the button battery 211 close to the movable buckle 231 is small and less than the elastic force exerted by the elastic member 24, thereby ensuring that part of the button battery 211 can be smoothly ejected from the battery accommodating cavity 22.

[0346] It should also be noted that the form of the elastic element 24 is not limited, and it can be a sheet or a spring, etc.

[0347] Furthermore, the power module 21 also includes battery contacts, which include a positive contact 213 and a negative contact 212. The positive contact 213 and the negative contact 212 are electrically connected to the positive and negative terminals of the button cell 211, respectively, and are also electrically connected to the PCB board 16. The negative contact 212 is disposed on the bottom wall of the battery housing 22 to make contact with the bottom wall of the button cell 211 for conducting electricity. The elastic element 24 includes the negative contact 212. Because the negative contact 212 is elastic and is disposed on the battery... The bottom wall of the receiving cavity 22 is such that the negative electrode spring 212 not only electrically connects the button battery 211 and the PCB board 16, but also provides a certain elastic force to the button battery 211 when it is disassembled, so that part of the button battery 211 pops out of the battery receiving cavity 22, improving the convenience of removing the button battery 211. That is, it has the function of the elastic element 24, so there is no need to set another elastic element 24, thereby simplifying the structure, saving internal space, and reducing production costs.

[0348] Specifically, the button battery 211 can be removed using tools for easy disassembly. However, to ensure stable installation of the button battery 211, the gap between the button battery 211 and the battery housing 22 is generally small, lacking sufficient space for tools to reach into the battery housing 22 and remove the button battery 211. Therefore, in some embodiments of the present invention, a battery removal groove 18c is provided on the lower housing 142. The battery removal groove 18c communicates with the button battery 211 housing and is located near the movable latch 231. When the engaging portion 2312 of the movable latch 231 moves away from the battery housing 22, i.e., away from the... When the button battery 211 is in use, the portion of the button battery 211 near the movable latch 231 is no longer fixed by the fastening part 2312. At this time, a disassembly tool can be used to pry the portion of the button battery 211 near the movable latch 231 out of the battery receiving cavity 22 by inserting it into the battery disassembly slot 18c and applying force to the button battery 211, making it easier to remove the button battery 211. It should be noted that the type of disassembly tool is not limited, as long as it can be inserted into the battery disassembly slot 18c to remove the button battery 211. Specifically, the disassembly tool can be a screwdriver, etc.

[0349] It should be noted that, based on the above embodiment where "the lower housing 142 is provided with two compensation holes 18b in a direction perpendicular to the bottom wall of the battery accommodating cavity 22, the two compensation holes 18b are respectively located on both sides of the elastic wall 221, and each compensation hole 18b is connected to the battery accommodating cavity 22, so that when the movable buckle 231 is subjected to force away from the battery accommodating cavity 22, the side wall of each compensation hole 18b near the elastic wall 221 undergoes elastic deformation in the direction toward the movable buckle 231, compensating for the elastic deformation of the part of the elastic wall 221 used to connect the movable buckle 231", when the size of the compensation hole 18b is set to be adapted to the disassembly tool, the compensation hole 18b can be the battery disassembly slot 18c. That is to say, the disassembly tool can be directly inserted into the compensation hole 18b to disassemble the button battery 211.

[0350] Specifically, in order to improve the installation stability of the button battery 211, the sidewall of the battery accommodating cavity 22 is adapted to the outer peripheral wall of the button battery 211; in this way, the limiting effect of the sidewall of the battery accommodating cavity 22 on the button battery 211 can be enhanced, thereby improving the installation stability of the button battery 211.

[0351] For details, please refer to Figure 57 , Figures 79 to 95 In some embodiments of the present invention, the power module 21 further includes battery contacts, which include a positive contact 213 and a negative contact 212. The positive contact 213 and the negative contact 212 are electrically connected to the positive and negative terminals of the button cell 211, respectively, and are also electrically connected to the PCB board 16. The electrical connection between the button cell 211 and the PCB board 16 is achieved through the positive contact 213 and the negative contact 212, thereby supplying power to the wireless communication module 13 and the detection element 12, so that the detection element 12 can send a trigger signal, and the wireless communication module 13 can receive the trigger signal and send a message.

[0352] It should be noted that the negative electrode spring 212 and the positive electrode spring 213 can be integrally formed or separate structures. For details, please refer to [link / reference needed]. Figures 79 to 95 In some embodiments of the present invention, the negative electrode spring 212 and the positive electrode spring 213 are both integrally formed structures, and are formed from a single base material sheet through processes such as cutting, stamping, and bending, thereby increasing the reliability of the battery spring and simplifying the processing.

[0353] Furthermore, the negative electrode area of ​​the button cell 211 generally includes the bottom wall of the button cell 211. However, in this invention, the bottom wall of the button cell 211 is the side wall of the button cell 211 facing the bottom shell 19. Correspondingly, the negative electrode spring 212 includes a negative electrode current-carrying piece 2121 and a negative electrode elastic contact arm 2122 connected to the negative electrode current-carrying piece 2121. The negative electrode current-carrying piece 2121 is in contact with the negative electrode of the PCB board 16 for conductivity. The negative electrode elastic contact arm 2122 is disposed corresponding to the battery accommodating cavity 22 to be in contact with the bottom wall of the button cell 211 for conductivity. This allows the negative electrode of the PCB board 16 to be electrically connected to the negative electrode of the button cell 211.

[0354] Furthermore, the position of the battery spring is set according to the position of the battery receiving cavity 22. In conjunction with the above description, "the lower housing 142 includes a bottom housing 19 and an isolation cover 18. The isolation cover 18 covers the bottom housing 19 and forms a receiving cavity 191 with the bottom housing 19. The PCB board 16 is received inside the receiving cavity 191. The isolation cover 18 has a first receiving through hole 222, and the PCB board 16 has a second receiving through hole 223. The battery receiving cavity 22 includes the first receiving through hole 222, and the first receiving through hole 222 and the second receiving through hole 223..." In an embodiment where the battery accommodating cavity 22 includes the first accommodating through hole 222 and the second accommodating through hole 223, when the button battery 211 is installed in the battery accommodating cavity 22, the bottom wall of the button battery 211 is located in the second accommodating through hole 223. Therefore, the negative electrode spring 212 is disposed between the bottom shell 19 and the PCB board 16, and the negative electrode elastic contact arm 2122 is disposed corresponding to the second accommodating through hole 223 to make contact with the bottom wall of the button battery 211 for conduction, thereby realizing the negative electrode spring 212 and the negative electrode contact conduction of the PCB board 16.
