[0124] The beneficial effects of the above-described technical solutions provided in the embodiments of the present invention include at least the following:

[0125] The button provided in this embodiment of the invention includes a thin-walled region and a thick-walled region. The thick-walled region secures the button, while the thin-walled region generates deformation, enabling effective triggering of the switching component under external force. It also possesses a self-restoring force, allowing for self-recovery. The integral molding design of the thin-walled and thick-walled regions achieves excellent waterproof and dustproof performance while maintaining a simple structure. The thick-walled region facilitates easy fixing of the button to other structures.

[0126] The switch assembly provided in this embodiment of the invention has a switch component positioned on a control board, and the thick-walled area of ​​the button is fixedly connected to the control board. This ensures that the assembly error of the switch component and the button is determined by the button and the control board, and the dimensions of other components do not affect the positioning accuracy of the switch component and the button. Even when the deformation of the thin-walled area of ​​the button is relatively small, the assembly dimensional accuracy of the switch component and the button can still be guaranteed.

[0127] This invention provides a signal transmitter that, based on a button, a bottom shell, and a seal, forms a waterproof sealed cavity. This simple structure achieves effective waterproof and dustproof sealing, meeting the needs of humid or dusty environments without requiring additional waterproof or dustproof design. The overall structure is simple, reliable, compact, and lightweight. Furthermore, based on the button, bottom shell, and seal, a fully functional signal transmitter module is formed, capable of independently transmitting signals under external force.

[0128] Effective light transmission can be achieved through a thin-walled structure, eliminating the need for a specially designed light-transmitting structure. This simplifies the design, facilitates implementation, saves space, and allows for a smaller, more compact signal transmitter with waterproof and dustproof capabilities. Alternatively, further thinning of the thin-walled area can achieve the same light transmission, simplifying the structure and providing waterproof and dustproof protection.

[0129] Another signal transmitter provided in this invention uses a button, a bottom shell, and a seal to form a waterproof sealed cavity. This simple structure achieves effective waterproof sealing, meeting the needs of use in humid environments without requiring additional waterproofing design. The overall structure is simple, reliable, compact, and lightweight. The button and bottom shell are fastened together by snap-fit ​​clips and / or anti-loosening clips, effectively preventing both separation and relative rotation. Once fastened, the button and bottom shell are securely fixed, ensuring more reliable installation.

[0170] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0171] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0172] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0173] To address the problems existing in the prior art, embodiments of the present invention provide a button. The switch assembly using this button utilizes a thick-walled region for button fixation and a thin-walled region to generate deformation, thereby enabling effective triggering of the switch component under external force and providing self-recovery. The integral molding design of the thin-walled and thick-walled regions achieves excellent waterproof and dustproof performance while maintaining a simple structure. The thick-walled region also facilitates easy fixing of the button to other structures. Specific embodiments are described in detail below.

[0174] Example 1

[0175] Embodiment 1 of the present invention provides a button, including a thin-walled region and a thick-walled region; wherein, the thickness of the thin-walled region is less than 2mm, the ratio of the area to the thickness of the thin-walled region is greater than 1177.5mm, and it can generate deformation under the action of external force; the thick-walled region is used to fix the button.

[0176] The aforementioned button features a thin-walled area with elasticity, allowing it to automatically reset upon removal of external force without requiring an additional reset support mechanism. This thin-walled area also possesses rigidity, directly triggering the switching component. While the thin-walled area provides the rigidity to trigger the switching component, it also has its own button return force, enabling self-reset. Furthermore, this thin-walled button also includes a thick-walled area, allowing for easy integration with other structures. In contrast, silicone buttons cannot achieve both self-support and automatic reset while possessing excellent rigidity for triggering; additionally, integrating silicone buttons with other structures is more complex.

[0177] For buttons with thin walls, on the one hand, it is desirable to have a large thin wall area to achieve a press-triggered switch structure over a wide range; on the other hand, if the thin wall area is too large and the thickness is too thin, it will be difficult to mold, reducing product yield. The inventors have determined through experiments that a thickness of 0.2–1 mm in the thin wall area is sufficient to produce an effective deformation-triggered switch component, preferably 0.5–0.7 mm. The thin wall area includes the button actuation area corresponding to the switch component position, and typically, under an external force of 1500g, the deformation of the button actuation area is not less than 0.69 mm.

[0178] To facilitate processing and molding, simplify the button structure, and effectively reduce costs by using the same material for the thin-walled part and other parts of the button, it is preferred that the thin-walled area and the thick-walled area be molded as one piece. The button material is plastic (with resin as the main material and some modified auxiliary materials added, such as color, fireproof, UV-resistant additives) or resin (PC, ABS, PC+ABS and other raw materials).

[0179] Optionally, the button can be designed in different shapes. In specific applications, the button is round or square. The outer part of the button is a thick-walled area, and the middle part is a thin-walled area. A button abutting arm is set at the center of the thin-walled area to abut against the switch component.

[0180] Optionally, one or more thin-walled regions can be provided for the button. When multiple thin-walled regions are provided, the button includes multiple thin-walled regions separated by thick-walled regions, with the thin-walled regions separated by thick walls. Preferably, the thickness of the gap between adjacent thin-walled regions is greater than the gap distance. For multiple thin-walled regions, the thickness of the gap between the thin-walled regions is greater than the gap between the thin-walled regions, which helps to reduce mutual interference between the thin-walled regions.

[0181] like Figure 1 The illustrated circular button includes a thin-walled region 111 and a thick-walled region 112. The thin-walled region 111 is located within the thick-walled region 112. A buffer region exists between the thin-walled and thick-walled regions, providing a gradual transition. To minimize defects from the integral molding of the thin and thick walls, the thin-walled region can be circular or elliptical. An abutment arm 13 is provided in the center of the thin-walled region 111. This facilitates integral molding and prevents significant molding defects. The abutment arm includes a central protrusion and a transition region that gradually thins from the center outwards. Figure 2 and Figure 3 The square button shown includes multiple thin-walled regions 111a, which are separated by thick-walled regions 112a. Each thin-walled region 111a has an abutment arm 13a in the middle. Figure 3 The cross-section of the thin-walled region 111a is shown in the figure.

[0182] Optionally, the above-mentioned button can be designed as a flat button or as a button with a sidewall. The button with a sidewall includes a button panel and a button sidewall. The button panel includes a thin-walled area and a thick-walled area. The thin-walled area is circular. The thickness of the button abutment arm is greater than the thickness of the thin-walled area. When the thin-walled area, including the abutment arm area, is pressed, the switch component is triggered. The button sidewall is a thick-walled area.

[0183] like Figure 1 The circular button shown can be designed as a flat button or it can include a button sidewall. Figure 1The example shown includes the button sidewall. The button includes a button panel 11 and a button sidewall 12. The button panel 11 includes a thin-walled area 111 and a thick-walled area 112. The button sidewall 12 and the thick-walled area 112 can also be referred to as the thick-walled area, as long as they can be distinguished from the thin-walled area and serve to fix the button and support the thin-walled area. The thin-walled area 111 is circular. The thickness of the button abutment arm 13 is greater than the thickness of the thin-walled area 111. When the thin-walled area, including the abutment arm area, is pressed, the switch component is triggered. The button sidewall 12 is the thick-walled area. The button low-mount arm and the button are integrally injection molded.

[0184] like Figure 2 The square button shown can be designed as a flat button or it can include button sidewalls. Figure 2 As shown, the button includes a button panel 11a and a button sidewall 12a. The button panel 11a includes a thick-walled region 112a and multiple thin-walled regions 111a. The thin-walled regions 111a are rectangular, and the multiple thin-walled regions 111a can be the same or different in shape. The multiple thin-walled regions 111a are separated by the thick-walled region 112a. The thickness of the button abutment arm 13a is greater than the thickness of the thin-walled regions 111a. When the thin-walled region, including the abutment arm region, is pressed, the switch component is triggered. The button sidewall 12a is a thick-walled region. Figure 2 The example shown is an 86-type switch with six thin-walled areas and six abutment arms. Supporting ribs 19a are also provided in the isolation areas between the thin-walled areas to reinforce these areas and further prevent mutual interference between the thin-walled areas, thus preventing accidental activation of the switching components corresponding to other thin-walled areas when pressing one thin-walled area.

[0185] The button provided in this embodiment of the invention includes a thin-walled region and a thick-walled region. The thick-walled region fixes the button and supports the thin-walled region. The deformation generated by the thin-walled region enables effective triggering of the switching component under external force, and it has a self-restoring force, allowing for self-recovery. Furthermore, the thin-walled region itself, or a low-mounted arm, can trigger the switching component, exhibiting superior rigidity compared to silicone materials. The thick-walled region provides a support point for the thin-walled region, facilitating easy connection with other components. The integral molding of the thin-walled and thick-walled regions saves production steps and costs, and the connection between the thin-walled and thick-walled regions provides a good seal, laying the foundation for subsequent design of waterproof and dustproof products.

[0186] The simulation effect of the displacement change of the button provided in Embodiment 1 of the present invention under the application of external force is as follows: Figure 4 and Figure 5 As shown, where, Figure 4 This is a schematic diagram illustrating the displacement change when an external force is applied to the central region of a thin-walled area. Figure 5This is a schematic diagram showing the displacement change when an external force is applied to a region of the thin-walled area that is off-center.

[0187] It is evident that the displacement change is greatest at the point of force application, then gradually decreases outwards. Changes in thickness and the area of ​​the thin-walled region both affect the displacement change; the larger the area of ​​the thin-walled region, the greater the displacement change. For the same area of ​​thin-walled region, the smaller the thickness, the greater the displacement. In practice, the pressing area of ​​the thin-walled region can be changed by altering these two parameters. For example, if a larger pressing area is desired, the thickness of the thin-walled region can be chosen; if a smaller pressing area is desired, the thin-walled region can be chosen to be thinner. Through simulation calculations and actual tests, the relationship between different areas and thicknesses can be demonstrated. Figure 6 The curve shown represents the relationship between displacement and the diameter of the circular thin-walled region. Under the same force (1500g) and the same thin-wall thickness (0.6mm), the ratio of the thin-walled region's area to its thickness needs to be greater than 1177.5mm² to ensure a displacement greater than 0.69mm. This is because a typical tactile button requires a displacement of approximately 0.3mm-0.5mm to trigger. Therefore, the thin-walled button needs to be designed with a displacement greater than that of a tactile button to ensure it can trigger the tactile button. Otherwise, the user experience will be poor, or it may even fail to function properly. Specifically, the pressing of a thin-walled button is not usually limited to the center; it can be pressed within a certain area. However, the detection point of the switch component is fixed. We can place the switch component in the center. In this case, if a non-center area is pressed, such as... Figure 4 and Figure 5 As shown, a larger ratio of area to thickness is needed for the thin-walled button to meet the requirements of pressing non-central areas. This design provides a suitable deformation allowance for the thin-walled button, ensuring a good tactile feel and meeting the conditions for frequent button pressing. It can be applied in environments where buttons are frequently triggered. Tests show that the pressing life of the thin-walled button can reach over 200,000 times.

[0188] Example 2

[0189] Embodiment 2 of the present invention provides a switching component, such as Figure 7 , Figure 8 As shown, it includes a switch component 5 and a button 1. The button 1 can be the button provided in Embodiment 1, and the switch component 5 can be implemented as a tactile switch.

[0190] Switch component 5 is mounted on control board 3;

[0191] The thick-walled area of ​​button 1 is fixedly connected to the control board 3, and its thin-walled area corresponds to the position of the switch component 5. It can abut against the switch component 5 under the action of external force, and can be reset when the external force is removed.

[0192] Optionally, one or more fixing posts can be provided in the thick-walled area of ​​the button for fixing the control board. The control board has fixing holes corresponding to the fixing posts. The fixing posts in the thick-walled area pass through the fixing holes of the control board and are fixed to the thick-walled area by heat fusion. The fixing posts on the thick-walled area of ​​the button are narrow strips. Optionally, there are more than one fixing post on the thick wall of the button, and at least one of them has a different shape from the other fixing posts. In this embodiment, there are four fixing posts, one of which, 171, is smaller than the other three fixing posts 172, 173, and 174. Similarly, one fixing hole 311 on the control board is adapted to fixing post 171, and the other three fixing holes 312, 313, and 314 are adapted to fixing posts 172, 173, and 174. This ensures that the control board can only be assembled in one direction during installation, guaranteeing the correct assembly direction.

[0193] like Figure 7 This is a structural diagram of a switch assembly, taking a circular button and a square control board as examples. In practical applications, the shapes of the buttons and control boards can be designed according to requirements. Figure 7 The switch assembly shown includes a button 1 and a switch component 5. The switch component 5 is mounted on the control board 3, and the button 1 is fixed to the control board 3 through the thick-walled area of ​​the button 1.

[0194] The switch component is positioned on the control board (PCB board), which is fixedly connected to the thick-walled area of ​​the button. This ensures that the assembly error of the switch component and the button is determined only by the button and the PCB board, and the dimensions of other components of the entire button do not affect the positioning accuracy of the switch component and the button. Because the button has a thin-walled design and relatively small deformation, this design ensures the dimensional accuracy of the assembly between the switch component and the button.

[0195] Example 3

[0196] Embodiment 3 of the present invention provides a signal transmitter, the structure of which is as follows: Figure 9 As shown, it includes a button 1, a bottom shell 2, a control board 3, and a seal 4.

[0197] The sealing element 4 mates with the button 1 and the bottom shell 2 to form a sealed cavity;

[0198] The control panel 3 is located inside the sealed cavity, and the control panel 3 is connected to the switch component 5;

[0199] When button 1 is subjected to external force, it is pressed and triggers switch component 5.

[0200] The control board 3 can be a PCB board with wireless signal transceiver capabilities. It contains wireless transceiver circuits, its antenna, and other circuits, and is connected to a switch component. Of course, the antenna can also be placed outside the circuit board and instead use a wire or helical antenna. If it is placed on the circuit board, there are certain requirements for the size of the circuit board. In practical applications, if the transmitted signal is a high-frequency signal of 2.4GHz, the antenna size requirement is relatively small, so the size of the circuit board can be minimized as much as possible, for example, by arranging it in a square shape. Such a square circuit board can save PCB material during the manufacturing process. If the signal is a high-frequency signal with a slightly lower carrier frequency, such as 433MHz, the antenna size requirement is higher. In order to reduce the overall size of the button, the PCB board can be made into a circle to fit the area of ​​the entire button. This maximizes the area of ​​the PCB board, allowing the antenna to be arranged around it.

[0201] This embodiment provides a waterproof signal transmitter. Button 1 in the transmitter is the same as the button provided in Embodiment 1; specifically, button 1 is a thin-walled button. This thin-walled button enables a light touch to trigger a switching component, which can also be a tactile switch. By adding sealing components, such as waterproof strips or rubber rings, a seal is formed between the button's fixing part and the bottom shell of the signal transmitter, achieving waterproofing without the need for additional waterproofing design. The structure is simple and reliable. The signal transmitter has a simple overall structure, is easy to operate and disassemble, facilitating user replacement or repair of internal components. It has a tight fit, is not easily loosened, and has good waterproof performance. Through the design of the thin-walled button and the waterproof sealing ring, a simple and reliable waterproof and dustproof function is achieved.

[0202] The button 1 of this signal transmitter is illustrated using a circular button as an example. In practical applications, the shape of the button can be designed according to needs. Button 1 and the bottom shell 2 can be assembled and disassembled. The sealing element 4 cooperates with button 1 and bottom shell 2 to achieve a seal. The control board 3 is installed in the sealed cavity. One or more fixing posts can be set on button 1 or bottom shell 2. The control board 3 can be fixed to the fixing posts by heat fusion, or it can be fixed by screws, hooks or other methods. Pressing the thin-walled area of ​​the button can trigger the switching component, which can be a tactile switch or other detection switch.

[0203] In the aforementioned signal transmitter, the sealing element 4, together with the button 1 and the bottom shell 2, forms a sealed cavity to achieve an effective waterproof seal. A waterproof seal can be formed by compressing the sealing ring after assembling the button 1 and the bottom shell 2. The waterproof seal can have different designs and different mating methods, as long as it ultimately achieves a seal through the mating of the sealing element with the button and the bottom shell, ensuring a waterproof effect.

[0204] See Figure 10The cross-sectional view of the signal transmitter shown illustrates an optional waterproof sealing design: the bottom shell 2 of the signal transmitter includes a bottom shell sidewall 21 and a bottom plate 22; the button 1 includes a button sidewall 12 and a panel 11; a first protrusion 113 is provided on the inner side of the panel 11, and the first protrusion 113 and the button sidewall 12 form a first sealing element mounting groove 114; the sealing element 4 is placed in the first sealing element mounting groove 114, and when the button 1 and the bottom shell 2 are engaged, the bottom shell sidewall 21 presses against the sealing element 4 to form a sealing cavity. This method places the sealing element 4 on the button 1, and the bottom shell 2 presses against the sealing element 4 to achieve a waterproof seal.

[0205] Another optional design for waterproof sealing is as follows: the bottom shell 2 includes a bottom shell sidewall 21 and a bottom plate 22; the button 1 includes a button sidewall 12 and a panel 11; a second protrusion is provided on the inner side of the bottom plate 22, and the second protrusion and the bottom shell 2 sidewall form a second sealing element mounting groove; the sealing element 4 is placed in the second sealing element mounting groove, and when the button 1 and the bottom shell 2 are engaged, the button sidewall 12 presses the sealing element 4 to form a sealing cavity. The second protrusion is similar to the first protrusion, except that it is located on the bottom shell 2. In this method, the sealing element 4 is placed on the bottom shell 2, and the button 1 presses the sealing element 4 to achieve waterproof sealing.

[0206] The seal can be clipped onto the button or onto the base shell. The first protrusion 113 or the second protrusion can also have different shapes, such as an annular rib, at least two arc-shaped ribs, or multiple columnar protrusions. That is, the protruding structure used to fix the sealing ring can be a ring-shaped protrusion or a four-corner protrusion. (Refer to...) Figure 8 As shown, the first protrusion is a series of discontinuous ribs or protrusions, such as Figure 8 181, 182, 183 shown, Figure 8 As shown, each rib protrusion corresponds to a positioning post, and there is a gap between each rib. One of the rib protrusions is not shown.

[0207] In the aforementioned signal transmitter, button 1 and bottom shell 2 can have different locking methods to ensure that the two can lock tightly together.

[0208] The first optional engagement method involves the bottom shell 2 and button 1 being fastened together using snap-fit ​​fasteners. One of the bottom shell 2 and button 1 has a male snap-fit ​​fastener, and the other has a female snap-fit ​​fastener. The male snap-fit ​​fastener is an assembly hook, and the female snap-fit ​​fastener is an assembly slot that matches the shape of the hook. After button 1 and bottom shell 2 are fastened together, the assembly hook is inserted into the assembly slot. The horizontal limiting surface of the assembly hook and the horizontal limiting surface of the assembly slot cooperate to prevent the button and bottom shell from separating. The left and right sides of the assembly hook and the left and right sides of the assembly slot cooperate to prevent the button and bottom shell from rotating. This method, by using snap-fit ​​fasteners to assemble bottom shell 2 and button 1, effectively prevents bottom shell 2 and button 1 from loosening vertically or horizontally. During disassembly, bottom shell 2 and button 1 are separated vertically to allow the assembly hook to disengage from the assembly slot.

[0209] The second optional engagement method is as follows: the bottom shell 2 and the button 1 are engaged by anti-loosening clips; one of the bottom shell 2 and the button 1 is equipped with an anti-loosening male clip, and the other with an anti-loosening female clip; the anti-loosening male clip is a fixed hook set in a groove, and the anti-loosening female clip is an elastic hook located in a hook hole. The spring end of the elastic hook is fixed to the side wall of the hook hole, and the hook end is a free end; after the button 2 and the bottom shell 1 are engaged, the hook end of the elastic hook is embedded in the groove and engages with the fixed hook. The vertical limiting surface of the fixed hook and the vertical limiting surface of the elastic hook cooperate to prevent the button 1 and the bottom shell 2 from rotating, and the upper and lower sides of the elastic hook and the upper and lower sides of the assembly groove cooperate to prevent the button 1 and the bottom shell 2 from separating. In this method, the assembly of the bottom shell 2 and the button 1 is achieved through anti-loosening clips, which can effectively prevent the bottom shell 2 and the button 1 from loosening vertically and horizontally. When disassembling, the bottom shell 2 and the button 1 are rotated relative to each other by a small angle in the direction of rotation, so that the elastic hook and the fixed hook disengage.

[0210] The third optional engagement method is as follows: the bottom shell 2 and the button 1 are engaged by a snap-fit ​​buckle and an anti-loosening buckle; one of the bottom shell 2 and the button 1 is equipped with a male snap-fit ​​buckle, and the other with a female snap-fit ​​buckle; and one of the bottom shell 2 and the button 1 is equipped with an anti-loosening male buckle, and the other with an anti-loosening female buckle; the male snap-fit ​​buckle is an assembly hook, and the female snap-fit ​​buckle is an assembly groove that matches the shape of the hook; the anti-loosening male buckle is a fixed hook set in the groove, and the anti-loosening female buckle is an elastic hook located in the hook hole, with the spring end of the elastic hook fixed to the side wall of the hook hole and the hook end being the free end; after the button 2 and the bottom shell 1 are engaged, the assembly hook is embedded in the assembly groove, and the horizontal limiting surface of the assembly hook and the horizontal limiting surface of the assembly groove cooperate to prevent the button and the bottom shell from separating; the hook end of the elastic hook is embedded in the groove and engages with the fixed hook, and the vertical limiting surface of the fixed hook and the vertical limiting surface of the elastic hook cooperate to prevent the button and the bottom shell from rotating. This method assembles the base shell 2 and button 1 using snap-fit ​​clips and anti-loosening clips. The snap-fit ​​clips restrict vertical movement, while the anti-loosening clips restrict horizontal movement, effectively preventing the base shell 2 and button 1 from becoming loose vertically or horizontally. During disassembly, rotating the base shell 2 and button 1 a small angle relative to each other in the direction of rotation causes the elastic hook and the fixed hook to disengage. After rotating a small angle, the assembly hook and the assembly slot will also disengage. The anti-loosening clip, composed of the elastic hook and the fixed hook, allows the base shell 2 and button 1 to be easily rotated and engaged during assembly, but requires slightly more force to rotate and disengage during disassembly.

[0211] like Figure 11 , Figure 12 and Figure 13 As shown, taking the simultaneous installation of fastening clips and anti-loosening clips as an example, the bottom shell 2 is provided with an assembly hook 23 as a fastening male clip, and the button 1 is provided with an assembly groove 14 adapted to the shape of the hook as a fastening female clip. At the same time, the bottom shell is provided with an elastic hook 24 located in the hook hole as an anti-loosening female clip, and the button 1 is provided with a fixing hook 15 located in the groove as an anti-loosening male clip. The anti-loosening clips are arranged symmetrically in two examples, and the fastening clips are arranged evenly around the circumference in four examples.

[0212] like Figure 14 This is an enlarged view of the retaining hook 15 located in the groove on the side wall of button 1. Figure 15 This is an enlarged view of the elastic hook 24 located in the hook hole on the bottom shell 21. The spring end 241 of the elastic hook 24 is fixed to the side wall of the hook hole 25, and the hook end 242 is the free end. Figure 16The diagram shows an enlarged view of the structure after the elastic hook and fixed hook are engaged. After the button 2 and the bottom shell 1 are fastened together, the assembly hook 23 is embedded in the assembly slot 14. The horizontal limiting surface of the assembly hook 23 and the horizontal limiting surface of the assembly slot 14 cooperate to prevent the button 1 and the bottom shell 2 from separating. The hook end 242 of the elastic hook 24 is embedded in the groove and engages with the fixed hook 15. The vertical limiting surface of the fixed hook 15 and the vertical limiting surface of the elastic hook 24 cooperate to prevent the button 1 and the bottom shell 2 from rotating. The side of the assembly slot 14 near the edge of the button sidewall will bear force after assembly, so this side is thickened. The thickness of the force-bearing side of the assembly slot is greater than the thickness of the non-force-bearing side. The added thickness is adapted to the gap between the bottom shell and the button assembly. Within the allowable gap range, the thickness of the edge of the assembly slot is increased as much as possible to ensure that the assembly slot and the buckle are stably engaged. The part of the slot 14 that enters the slot has a certain slope to ensure that the buckle can enter smoothly.

[0213] like Figure 17 As shown, when the elastic hook is set on the side wall of the bottom shell or the side wall of the button, the position of the elastic hook on the side wall of the bottom shell or the side wall of the button is a double-layer side wall with an arc-shaped hole between the two layers. One layer of the side wall has a hook hole to accommodate the elastic hook. Through the design of the double-layer side wall structure, although the hook hole is opened on the outer wall, the existence of the inner wall can still achieve a good waterproof effect and ensure the sealing and waterproof performance. In other words, through the design of the double-layer side wall, the inner wall, the waterproof seal and the button form a waterproof cavity, while the snap-fit ​​and other moving mechanisms are set on the outer wall without affecting the waterproof effect.

[0214] Optionally, the signal transmitter described above also includes a light-emitting component 61 and a focusing component 62. For example... Figure 9 and 18 As shown, the light-emitting component is connected to the control board 3, and the light-concentrating component 62 surrounds the light-emitting component 61. The light-emitting component 61 and the light-concentrating component 62 can have different design forms in practical applications. Generally, the light-emitting area corresponding to the light-emitting component 61 is located within the thin-walled area to facilitate the transmission of light. To further improve the light transmission effect, the thin-walled area can be further thinned to form the light-emitting area.

[0215] The light-emitting component 61 can be an LED, and the light-focusing component 62 can be a ring-shaped foam. The ring-shaped foam is attached to the PCB, surrounding the LED and acting as a light-focusing element. Pressing the center area of ​​the button triggers a detection switch, at which point the transmitter emits a signal, and the LED lights up. The light emitted by the LED is focused by the ring-shaped foam and passes directly through the thin wall of the button, eliminating the need for an additional light guide column and achieving a relatively good waterproof effect.

[0216] One arrangement of the light-emitting component 61 and the focusing component 62 is as follows: the light-emitting component 61 is disposed on the control panel 3, and the focusing component 62 surrounds the light-emitting component 61 and is located within the coverage area of ​​the thin-walled region of the button 1.

[0217] Among them, the light-concentrating component 62 is a flexible component that can deform with the deformation of the thin-walled region.

[0218] The thickness of the thin-walled region corresponding to the light-emitting area of ​​the light-emitting component 61 is less than the thickness of other parts of the thin-walled region, so as to facilitate the transmission of light.

[0219] Another optional arrangement of the light-emitting component 61 and the focusing component 62 is as follows: the light-emitting component 61 is set on the control panel 3, and the focusing component 62 surrounds the light-emitting component and is located within the coverage area of ​​the thick-walled area of ​​the button. The light-emitting area corresponding to the thick-walled area needs to be thinned to achieve good light transmission and waterproof and dustproof effect.

[0220] The control board 3 of the aforementioned signal transmitter can be mounted on either the button 1 or the base shell 2, and it also includes a structure for mounting a battery. For example, a mounting bracket for the control board can be provided inside the button or the base shell. A switch component 5 is mounted on top of the control board, and a battery mounting bracket 71 is mounted below it. A battery 72 can be inserted into the battery mounting bracket.

[0221] like Figure 18 As shown, the battery mounting base 71 is located below the control board 3, the switch component is located above the control board 3, and the battery is on the other side of the switch component 5. This ensures that both the switch component 5 and the battery 72 are centered, which helps to reduce the product size, provides sufficient space for the battery, increases the flexibility of battery selection, keeps the product's center of gravity in the center, and improves the product's user experience. When the battery needs to be replaced, turn the button 1 with a little force to disengage the latch and / or anti-loosening latch, and then remove the button 1. If the control board 3 is installed on the button, the control board 3 will be removed at the same time. If the control board 3 is installed on the bottom shell 2, the control board 3 will be removed. At this time, the battery can be replaced. After replacement, reassemble.

[0222] The battery mounting bracket 71 can be designed to allow the battery to be installed vertically or sideways.

[0223] like Figure 18 and 19As shown, one optional structure for vertical battery insertion is that the battery mounting base 71 includes multiple elastic tabs 711 mounted below the control board 3. These elastic tabs 711 form an annular battery receiving groove that allows the battery to be inserted from a direction perpendicular to the bottom surface of the control board. The multiple elastic tabs 711 cooperate to secure the battery 72 inserted into the battery receiving groove, ensuring that the positive and negative terminals of the battery 72 contact the positive and negative terminals on the control board, respectively. The battery 72 is vertically inserted into the battery mounting base, facilitating battery replacement.

[0224] like Figure 20 , 21 As shown in Figures 22 and 23, an optional structure for side-mounted batteries can be that the battery mounting base 71 includes a battery tray 712 fixed below the control board. The battery tray 712 has a battery inlet / outlet on at least one side. After the battery is inserted into the conductive battery tray, one of its positive and negative terminals contacts the conductive tray, and the other terminal contacts the electrode 31 on the control board. The battery is inserted or removed from the side, and the negative terminal of the battery directly uses a PCB pad, eliminating the need for soldering an additional negative terminal, thus saving costs. The control board can adopt different shapes such as square or round, and the board shape can be selected according to the actual situation, especially the layout of the wireless signal transmitting antenna. Figure 20 and 21 This is an example diagram of a circular control panel. Figure 22 This is an example diagram of a square control panel. Figure 20 Taking the control panel shown as fixed on button 1 as an example, button 1 has four fixing posts 17, one of which is smaller than the others.

[0225] like Figure 24 , Figure 25 , Figure 26 An example diagram showing a battery holder with a battery tray 712 on the control board 3, wherein... Figure 24 for Figure 25 The right view shows the structure above the control panel. Figure 26 for Figure 25 The left view shows the structure beneath the control board. Optionally, electrodes 31 for contacting the battery are drawn on the control board 3 using copper foil on the PCB. The electrodes can be drawn in a grid pattern. The electrode surfaces are tin-plated or immersed. Furthermore, a reflective layer 63 can be applied to a certain area centered on the light-emitting component 61 on the control board 3, which facilitates light transmission from the thin-walled area of ​​the button. This reflective layer can be a white silkscreen used in PCB manufacturing, which can be directly fabricated during PCB production without increasing costs.

[0226] The shape of the electrode 3, drawn on the copper foil of the PCB on the control board 3, can be designed as needed. For example, it can be circular, and the electrode area is larger than the surface area of ​​the battery's electrode terminals used for contact, ensuring good contact between the battery electrode and the PCB electrode. Optionally, in addition to the circular shape, the electrode on the control board also includes a square structure on one side. This square structure is located on the battery inlet / outlet side, ensuring that the entire diameter of the battery is occupied by electrodes during inlet / outlet operation, without any other possible PCB traces. Figure 26 The upper half of the electrode 31 shown is circular, and the lower half is square; it can be either rectangular or square.

[0227] A support member 73 for auxiliary support of the battery mounting base can also be provided below the battery mounting base. The support member 73 is installed inside the bottom plate 22 of the bottom shell 2 or below the battery mounting base 71. This support member can be a ring-shaped support member, specifically a ring-shaped foam, which is attached to the bottom shell 2 to help fix the battery and prevent it from falling off, and can also help support the control board.

[0228] like Figure 27 As shown, multiple support ribs 223 can also be provided on the bottom shell 2. The support ribs 223 are used to assist in supporting the control board and to limit the battery position. Figure 27 Taking the four support ribs as an example, on the one hand, they can assist in supporting the control plate 3; on the other hand, for the side battery mounting base, the support ribs can limit the battery and prevent the battery from sliding out of the effective contact area.

[0229] The aforementioned signal transmitter also includes a permanent magnet 74 that can be attached to the battery mounting base or the battery. The permanent magnet 74 is located within the area surrounding the support member 73. When using a side-mounted battery design, the permanent magnet can be used more conveniently, directly attaching to the battery mounting base or the battery. This allows the signal transmitter to be directly attached to ferrous or magnetic surfaces during use, without the need for additional methods such as double-sided tape or screws for fixation. Simultaneously, the aforementioned support member can use adhesive-backed ring-shaped foam, which is attached to the battery mounting base or bottom shell. This serves two purposes: firstly, it supports the battery mounting base, preventing the battery mounting base pads from detaching; secondly, it encircles the permanent magnet, preventing it from sliding freely.

[0230] Example 4
