Abstract
Description
[0001] This application is a divisional application. The original application's application number is 202323456669.5, and the original application's invention title is... The application is for a smart switch, and the original application date was December 16, 2023. Technical Field
[0002] This application relates to the field of switches, and more particularly to a smart switch. Background Technology
[0003] With the development of smart homes, smart switches have gradually been used to replace traditional mechanical switches due to their advantages such as intelligence, diversified control, and convenient operation. As a triggering device for smart homes, smart switches play a very important role in the entire system, and more and more users are choosing smart switches to control indoor electrical appliances during home renovation.
[0004] For multi-button smart switches, users are easily confused about the corresponding functions of each button. Most existing smart switches pre-print text or patterns on the buttons to indicate their functions. If the function of a button is changed, the button needs to be replaced accordingly, which causes inconvenience to users and results in waste. Utility Model Content
[0005] One objective of this invention is to provide an intelligent switch in which multiple independent displays show the function information of each button. Users can change the content displayed on the screens to adapt to changes in button functions, solving the problem in the prior art where changing the pattern or text requires replacing the buttons. Furthermore, the advantage of using multiple displays compared to using a single display is that it improves the effective utilization rate of the display area of a single display, reduces blank areas, and allows for individual replacement of a damaged display, saving on maintenance costs.
[0006] Another objective of this invention is to provide an intelligent switch in which the ends of each button are connected to each other via connecting ends, thereby making the positional correspondence between the buttons and the display screen more accurate. At the same time, since the ends of each button are connected, each button can provide a reset force to each other, eliminating the need for an additional reset structure and simplifying the structure. Furthermore, the connection of each button prevents the buttons from wobbling or becoming loose, improving the pressing feel.
[0007] Another objective of this utility model is to provide an intelligent switch in which the pressing part adopts a combination of a plug-in structure and an abutment structure, so that the pressing part can be completely disassembled from the panel base without disassembling each button individually, thus avoiding the breakage of the connection ends of each button. Therefore, the pressing part disassembly scheme provided in this embodiment is more suitable for the row of buttons structure of this utility model.
[0008] Another objective of this invention is to provide an intelligent switch in which, when the pressing end is pressed, the pressing end moves with the supporting limiting structure as the fulcrum, and the plug-in position provides the plug-in structure with a resisting force in the second direction, so that the pressing end generates a reset force, thereby eliminating the need for an additional reset structure for the button and simplifying the structure.
[0009] Another objective of this invention is to provide an intelligent switch in which the snap-fit rotating structure improves the connection stability between the two sides of the pressing part and the panel base. When the button is pressed, the snap-fit rotating structure can also provide support and limiting force, making the pressing movement of the button more stable and reliable. Furthermore, when the pressing part is disassembled, if the movable snap-fit structure disengages from the panel base, the snap-fit rotating structure can provide auxiliary snap-fit force to prevent the pressing part from falling off.
[0010] Another objective of this utility model is to provide an intelligent switch in which the opening direction of the card interface is inclined, making the installation and disassembly of the pressing part simple and convenient. Furthermore, the combination of the card-connecting rotation structure and the abutting structure allows the pressing part to be disassembled and installed more conveniently as a whole, avoiding damage to the connection end by disassembling each button individually.
[0011] Another objective of this invention is to provide an intelligent switch in which the connecting structure is recessed in the first surface of the pressing part, so that when one button is pressed, the other buttons will not follow suit; and the connecting structure protrudes from the second surface of the pressing part to enhance the strength of the connection between the buttons.
[0012] Another objective of this invention is to provide an intelligent switch in which, when disassembling the display screen, only the circuit board needs to be removed to disassemble each display screen individually. The disassembly process does not affect the assembly status of other display screens, making it more suitable for the structure of multiple display screens in this invention embodiment. Moreover, the transparent cover does not need to be removed during the disassembly process, reducing the difficulty of disassembly and assembly.
[0013] Another objective of this invention is to provide a smart switch in which the ribbon cable is oriented in a third direction, making the distance between the display screen and the button closer and the indication effect better; and avoiding the stacking of the ribbon cable and the pressing part in the thickness direction, thereby reducing the thickness of the smart switch and preventing the movement of the pressing part from causing damage to the ribbon cable.
[0014] Another objective of this invention is to provide an intelligent switch in which a preset gap is provided between the transparent cover and the display screen, thereby increasing the creepage distance between the display screen and the upper surface of the transparent cover.
[0015] Another objective of this invention is to provide an intelligent switch in which a blank area is provided at one end of the display area facing the fourth direction, and no content is displayed in the blank area to avoid the display content being blocked by the light-blocking layer.
[0016] Another objective of this invention is to provide an intelligent switch in which at least one display screen is positioned between an infrared LED and an infrared receiver, thereby increasing the distance between them and reducing total internal reflection of the detection wave within the transparent cover. A shielding element surrounds the infrared LED, blocking detection waves from the sides of the LED, thus reducing the likelihood of the detection wave passing through the gap between the panel substrate and the circuit board or penetrating the panel substrate to reach the infrared receiver unit. These two solutions reduce the transmission of the detection wave within the intelligent switch, preventing false detections by the infrared detection device.
[0017] Another objective of this invention is to provide an intelligent switch in which the emission angle of the detection wave is limited to less than 90° by the emission window, so as to avoid the infrared detection device being falsely triggered due to an excessively large detection angle.
[0018] To achieve at least one of the above objectives, this utility model provides an intelligent switch, including a panel base, a pressing part, and a display device. The pressing part is connected to the panel base and includes multiple buttons. The display device includes multiple display screens corresponding to each of the buttons.

For example, it can refer to a fixed connection, a detachable connection, or an integral part; 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 utility model according to the specific circumstances.
[0079] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by the present utility model.
[0080] Currently, most button-type smart switches pre-print text or images on the buttons to indicate their functions. If the user changes the function of a button, the button itself needs to be replaced, which is inconvenient and wasteful. To solve this problem, please refer to... Figures 1-24 This utility model provides a smart switch 100, which is specifically illustrated below. For example... Figures 1-5As shown, the smart switch 100 includes a panel base 1, a pressing part 2, and a display device 10. The pressing part 2 is connected to the panel base 1 and includes multiple buttons 21. The display device 10 includes multiple display screens 101 corresponding to each button 21. Each display screen 101 is disposed on the panel base 1 and is used to display the button information of the corresponding button 21. The smart switch 100 provided by this utility model can display the information corresponding to each button 21 through the display screens 101. Users can change the content displayed on the display screens 101 to adapt to changes in button functions, solving the problem in the prior art that the pattern or text needs to be changed by replacing the buttons 21. The one-to-one correspondence between the display screens 101 and the buttons 21 can be understood as the number of display screens 101 being equal to the number of buttons 21, and their positions corresponding to the positions of the buttons 21. For example, each display screen 101 can be located near the end of each button 21. The advantage of using multiple independent displays 101 compared to using a single display 101 is that it improves the effective utilization rate of the display area of a single display 101, reduces blank areas, and when one of the displays 101 is damaged, it can be replaced individually, saving maintenance costs.
[0081] In addition, such as Figures 1-5 As shown, in the smart switch 100 provided by this utility model, one end of each of the buttons 21 is connected to form the connection end 22 of the pressing part 2, and the other end of each button 21 away from the first end is separated to form the pressing end 23 of the pressing part 2. This ensures that when one button 21 is pressed, the other buttons 21 will not move accordingly, and each button 21 provides a reset force to each other through the connection end 22. Each display screen 101 is positioned close to the connection end 22. The connection of one end of each button 21 can be integrally formed, fixedly connected by a fixing piece, or other forms of connection. The mutual reset force provided by each button 21 can be understood as follows: the ends of each button 21 are connected through the connection end 22. When one button 21 is pressed, the button 21 causes the connection end 22 to move, while the connection end 22 remains stationary due to the connection of the other buttons 21. This causes deformation of the connection end 22 and the pressed button 21, thereby generating a reset force. The fact that the display screen 101 is located near the connection end 22 can be understood as each display screen 101 being located near the end of each button 21 in a corresponding manner.
[0082] The intelligent switch 100 provided by this utility model has its ends of each button 21 connected to each other, so that the spacing between each button 21 is consistent, and the positional correspondence between the button 21 and the display screen 101 is more accurate. At the same time, since the ends of each button 21 are connected, each button 21 can provide a reset force to each other, eliminating the need for an additional reset structure and simplifying the structure. Furthermore, the connection of each button 21 prevents the button 21 from shaking or becoming loose, improving the pressing feel.
[0083] According to embodiments of the present invention, such as Figure 9 and Figure 13 As shown, the smart switch 100 also includes a bottom shell 3, which has a mounting hole 31 for external installation. The pressing part 2 covers the mounting hole 31. When installing the smart switch 100, the user only needs to remove the pressing part 2 to expose the mounting hole 31, and then pass the mounting screw 32 through the mounting hole 31 to connect it to the wall junction box, thereby fixing the smart switch 100 to the wall. The installation process does not require removing the panel base 1, which protects the internal circuit board 5 and avoids the risk of the circuit board 5 falling and breaking after being removed along with the panel base 1.
[0084] Since the smart switch 100 provided by this utility model requires the button 21 to be disassembled before it can be installed externally, the button 21 needs to be easy to disassemble and assemble. Furthermore, each button 21 should not be disassembled individually during disassembly and assembly to avoid breaking the connecting ends 22 of each button 21. Based on this, this utility model embodiment provides a series of buttons 21 that are easy to disassemble and assemble, including a plug-in structure 241, an abutment structure 242, and a movable snap-fit structure 243. These three structures cooperate with each other to achieve the effect of easy disassembly and assembly of the button 21. Figure 6 , Figure 3 and Figure 9 As shown, the connecting end 22 of the pressing part 2 is provided with the insertion structure 241, and the panel base 1 is provided with the insertion position 11. The insertion structure 241 is inserted into the insertion position 11 and is restricted by the insertion position 11 to move in the fifth direction. The fifth direction is opposite to the direction in which the button 21 is pressed. Figure 5 This is a top view of the smart switch 100. Figure 6 for Figure 5 In the AA-step sectional view, it should be noted that the insertion structure 241, the abutment structure 242, and the movable snap-fit structure 243 are not on the same vertical plane (by...). Figure 3 It can be seen that... Figure 6 By using a stepped sectioning method to concentrate the three elements onto the same cross-section, the structure can be displayed more intuitively. The fifth direction is... Figure 6 The fifth direction is already in the vertical upward direction. Figure 6The selected structure is the plug-in structure 241, which can be a tongue, pin, plate, or other plug-in structure. The insertion direction of the plug-in structure 241 can be... Figure 6 The horizontal direction can be an upward or downward tilting direction. The plug-in position 11 can abut against the upper surface of the plug-in structure 241 during the movement of the button 21 to restrict the movement of the plug-in structure 241 toward the fifth direction.
[0085] The connecting end 22 of the pressing part 2 is provided with the abutting structure 242 facing the second direction. The abutting structure 242 is disposed between the insertion structure 241 and the pressing end 23. The second direction is the same as the direction in which the button 21 is pressed. Figure 6 The vertical downward direction is already in the second direction. Figure 6 The panel base 1 has a supporting and limiting structure 12 at the corresponding position of the abutting structure 242. The abutting structure 242 abuts against the supporting and limiting structure 12. The supporting and limiting structure 12 can restrict the insertion structure 241 from disengaging from the insertion position 11. When the abutting structure 242 abuts against the supporting and limiting structure 12, the two cooperate to restrict the button 21 from moving horizontally, thereby restricting the insertion structure 241 from disengaging from the insertion position 11 to the right. Figure 7 The diagram shows a schematic of the pressing end 23 of the pressing part 2 under pressure. When the pressing end 23 is pressed, it moves around the support limiting structure 12. For example, the button 21 can pivot around the support limiting structure 12, thereby driving the pressing end 23 to move; or the button 21 can deform around the support limiting structure 12, and the deformation of the button 21 can drive the pressing end 23 to move downward, thereby triggering the detection element 52. Each button 21 has a movable latching structure 243 near the pressing end 23 facing the second direction. The movable latching structure 243 is latched onto the panel base 1, which can restrict the pressing end 23 of the button 21 from detaching from the panel base 1 in the fifth direction, and the movable latching structure 243 can move in the second direction.
[0086] like Figure 8 As shown, Figure 8 for Figure 6The diagram illustrates the disassembly process of the pressing part 2. When the pressing part 2 is disassembled from the panel base 1, the user can first pry the pressing end 23 upwards, causing each of the movable locking structures 243 to disengage from the panel base 1. The pressing part 2 can then rotate counterclockwise based on the insertion structure 241. When the rotation angle reaches a certain value, the abutting structure 242 disengages from the supporting limiting structure 12, thereby freeing the pressing part 2 from the restriction of the supporting limiting structure 12, allowing the insertion structure 241 to disengage from the insertion position 11 to the right. The entire disassembly process is simple and quick, suitable for the feature of the smart switch 100 requiring the pressing part 2 to be disassembled before external installation. Moreover, compared to the prior art where each button 21 is provided with a hole for rotational connection with the panel base 1, this embodiment adopts a scheme in which the plug-in structure 241 and the abutment structure 242 cooperate, so that the pressing part 2 can be completely disassembled from the panel base 1 without disassembling each button 21 one by one, thus avoiding the connection end 22 connecting each button 21 from being broken. Therefore, the disassembly scheme of the pressing part 2 provided in this embodiment is more suitable for the row of buttons 21 structure of this utility model.
[0087] Correspondingly, the installation process of the pressing part 2 is the reverse of the disassembly process, such as... Figure 8 As shown, when the pressing part 2 is installed on the panel base 1, the plug-in structure 241 can be inserted into the plug-in position 11 at an angle to the lower left. Then, the pressing part 2 is rotated clockwise based on the plug-in structure 241, so that the abutting structure 242 abuts against the supporting limiting structure 12. Finally, the pressing end 23 is pressed down, so that the movable locking structure 243 is locked onto the panel base 1, completing the installation. The entire installation process is quick and convenient, which is suitable for the characteristic that the smart switch 100 of this utility model needs to have the pressing part 2 installed on the panel base 1 after being installed on the wall.
[0088] Furthermore, such as Figure 8 As shown, during the installation and removal of the pressing part 2, when the pressing part 2 is tilted, the left end of the pressing part 2 abuts against the transparent cover plate 4. To ensure that the pressing part 2 can be installed and removed smoothly, as follows... Figure 6 As shown, there is a certain gap between the left end of the pressing part 2 and the transparent cover plate 4. This gap is reserved for the pressing part 2 to rotate, so that when the pressing part 2 is tilted during the installation and disassembly of the pressing part 2, the transparent cover plate 4 will not interfere with the pressing part 2.
[0089] According to embodiments of the present invention, such as Figure 7 and Figure 6As shown, the insertion position 11 abuts against the side of the insertion structure 241 facing the fifth direction. When the pressing end 23 is pressed, the pressing end 23 moves with the support limiting structure 12 as the fulcrum. The insertion position 11 provides the insertion structure 241 with an abutting force facing the second direction, causing the pressing end 23 to generate a restoring force. The pressing part 2 is equivalent to a seesaw structure with the support limiting structure 12 as the fulcrum. The insertion position 11 restricts the left end of the pressing part 2 from moving upwards through the insertion structure 241. When the pressing end 23 located at the right end of the pressing part 2 is pressed, the pressing end 23 moves downwards. Because the left end of the pressing part 2 is restricted from moving upwards, the pressed button 21 bends and deforms, while the other unpressed buttons 21 remain in their initial state. The deformation of the buttons 21 generates a restoring force, which is set as the first restoring force. Secondly, since the buttons 21 are interconnected via the connecting end 22, they can also provide a reset force to each other, which is designated as the second reset force. In addition, the button 21 presses against the detection element 52, causing the detection element 52 to generate a reaction force on the button 21, which is designated as the third reset force. When the pressing force is removed, the pressed button 21 resets under the combined action of the first, second, and third reset forces, eliminating the need for an additional reset structure and simplifying the structure.
[0090] Furthermore, the detection element 52 is selected from one of a tactile switch, a micro switch, a detection switch, a membrane switch, and a Hall switch. In a preferred embodiment, the detection element 52 is selected from a tactile switch.
[0091] Furthermore, such as Figure 6 As shown, the detection element 52 is provided on the side of the circuit board 5 facing the panel substrate 1. A trigger post 211 is provided on the button 21 facing the detection element 52. The button 21 triggers the detection element 52 through the trigger post 211. When the button 21 is not pressed, the detection element 52 is still pressed against the trigger post 211, generating a small amount of compression. This compression is insufficient to trigger the detection element 52, but it provides preload to the button 21, preventing it from feeling loose and providing a firmer pressing feel. Furthermore, this compression ensures that the trigger post 211 and the detection element 52 remain in contact, eliminating the gap between them and thus eliminating the button 21's free travel and improving its trigger sensitivity. Further, as... Figure 3 , Figure 6 and Figure 9 As shown, the plug-in structure 241 includes a tongue disposed from the connecting end 22 toward a third direction. The tongue is inserted into the plug-in position 11 and is restricted by the plug-in position 11 from moving toward the fifth direction. The third direction is the direction from the pressing end 23 of the pressing part 2 toward the connecting end 22. Figure 6 The middle horizontal direction to the left, the third direction is already Figure 6 and Figure 3 The key is marked. In a specific embodiment, the connecting end 22 of the pressing part 2 extends into an extension wall 2411 in the second direction, and the bottom end of the extension wall 2411 protrudes into the third direction with the tongue; the number of the tongues is set to two, and the two tongues are arranged at intervals along the first direction, which is set as the arrangement direction of the button 21. The first direction has already been marked. Figure 3 The selected element is shown in the diagram. The number of abutting structures 242 is set to two, with the two abutting structures 242 arranged at intervals along a first direction, and located between two insertion structures 241 in the first direction. Additionally, each button 21 is provided with one movable latching structure 243 and one trigger post 211, with each movable latching structure 243 and each trigger post 211 arranged along the first direction. It is worth noting that, in the third direction, the movable latching structure 243, trigger post 211, abutting structure 242, and insertion structure 241 are arranged sequentially. Further, as shown in the diagram... Figure 9 As shown, the insertion position 11 includes a horizontally arranged limiting rib, which abuts against the upper surface of the tongue to restrict the upward movement of the tongue.
[0092] Furthermore, such as Figure 6 and Figure 3 As shown, the support limiting structure 12 is constructed as a first rotating shaft 121. The abutment structure 242 is provided with a flared abutment recess 2421 facing the first rotating shaft 121. The abutment recess 2421 abuts against the first rotating shaft 121 to restrict the pressing part 2 from translating in the opposite direction to the third direction, thereby restricting the insertion structure 241 from disengaging from the insertion position 11. Here, "flared" includes all flared shapes, and does not specifically refer to a precise flared shape. Figure 9 As shown, the first rotating shaft 121 is integrally formed on the panel base 1. The number and position of the first rotating shaft 121 correspond one-to-one with the abutment recess 2421, and each of the first rotating shafts 121 is coaxially arranged.
[0093] Furthermore, when button 21 is pressed, the pressing part 2 will rotate slightly based on the first rotating shaft 121, therefore, as Figure 6 and Figure 7 As shown, the top of the abutment recess 2421 is set to be arc-shaped, and its curvature is consistent with the curvature of the first rotating shaft 121, so that the abutment recess 2421 can fit against the first rotating shaft 121 to rotate, thereby making the pressing feel smoother.
[0094] Furthermore, such as Figures 6-9As shown, the movable latching structure 243 is constructed as a first latch extending from the button 21 toward the second direction. The panel base 1 is provided with a first latching position 13 adapted to the first latch. The movable latching structure 243 latches onto the first latching position 13. The first latching position 13 has reserved space for movement in the second direction, so that the first latch can move toward the second direction.
[0095] According to embodiments of the present invention, such as Figure 3 , Figure 9 and Figure 10 As shown, the pressing part 2 has locking and rotating structures 244 on both sides facing the second direction. The panel base 1 has a second rotating shaft 14 at a corresponding position to the locking and rotating structures 244. The locking and rotating structures 244 are locked to the second rotating shaft 14 and can rotate based on the second rotating shaft 14. The second rotating shaft 14 is coaxially arranged with the first rotating shaft 121. The function of the locking and rotating structures 244 is to improve the connection stability between the pressing part 2 and the panel base 1. When the button 21 is pressed, the locking and rotating structures 244 can also provide support and limiting force, making the pressing movement of the button 21 more stable and reliable. Furthermore, when disassembling or assembling the pressing part 2, if the movable locking structure 243 disengages from the panel base 1, the locking and rotating structures 244 can provide auxiliary locking force to prevent the pressing part 2 from falling off. Figure 10 This is a simplified assembly diagram showing the structure of the pressing part 2 and the panel base 1. Figure 10 Some of the structures in it have been simplified, but Figure 10 The plug-in structure 241, the snap-fit rotating structure 244, and the movable snap-fit structure 243 are in the middle. Figure 3 and Figure 9 To maintain consistency, it should be noted that the plug-in structure 241, the snap-fit rotation structure 244, and the movable snap-fit structure 243 are not on the same vertical plane (by...). Figure 3 It can be seen that... Figure 10 By using a stepped section method to concentrate the three elements on the same cross section, the structure can be displayed more intuitively.
[0096] Furthermore, such as Figure 10 As shown, the snap-fit rotating structure 244 includes a rotating hole 2441 and a snap-fit interface 2442 communicating with the rotating hole 2441. The second rotating shaft 14 is snapped into the rotating hole 2441 by the snap-fit interface 2442. The opening direction of the snap-fit interface 2442 is set as an inclined direction between the second direction and the third direction, wherein the third direction is the direction from the pressing end 23 of the pressing part 2 toward the connecting end 22. The second direction and the third direction are already... Figure 10 The winning bid was selected. Among them, Figure 10The document contains three diagrams, each corresponding to one of three states during the installation of the pressing part 2. The first state is the state where the pressing part 2 is detached; the second state is the state during the installation of the pressing part 2; and the third state is the state where the pressing part 2 is installed. In the second state, the insertion structure 241 of the pressing part 2 is inserted obliquely into the insertion position 11 facing downward to the left. The locking interface 2442 of the locking rotating structure 244 abuts against the second rotating shaft 14, and the movable locking structure 243 has not yet been locked into the panel base 1. At this time, due to the overall tilt of the pressing part 2, the opening direction of the locking interface 2442 is exactly vertically downward. When the pressing part 2 rotates downward based on the insertion structure 241, the movement direction of the locking interface 2442 is exactly consistent with the opening direction of the locking interface 2442, allowing the locking interface 2442 to be smoothly locked into the second rotating shaft 14. Subsequently, the movable locking structure 243 is locked into the first locking position 13, and the installation is completed. Furthermore, the disassembly process of the pressing part 2 is the reverse of the installation process. During disassembly, the movable locking structure 243 is first disengaged from the first locking position 13, and then the pressing part 2 is rotated upward based on the insertion structure 241. This allows the locking rotating structure 244 to disengage from the second rotating shaft 14. At this time, the abutting structure 242 also disengages from the supporting limiting structure 12, allowing the insertion structure 241 to disengage from the insertion position 11, thereby disassembling the pressing part 2. In this embodiment of the present invention, since the opening direction of the card interface 2442 is inclined, the installation and disassembly process of the pressing part 2 is relatively simple and convenient. Moreover, the cooperation between the locking rotating structure 244 and the abutting structure 242 makes it easier to disassemble and install the pressing part 2 as a whole, avoiding damage to the connecting end 22 by disassembling each button 21 one by one.
[0097] Furthermore, such as Figure 4 and Figure 3As shown, the buttons 21 at corresponding positions of the connecting end 22 are connected by a connecting structure 25. The connecting structure 25 is recessed in the first surface 27 of the pressing part 2, so that when one button 21 is pressed, the other buttons 21 will not follow suit. The first surface 27 is the side of the pressing part 2 facing away from the second direction. The connecting structure 25 protrudes from the second surface 28 of the pressing part 2 to enhance the connection strength between the buttons 21. The second surface 28 is the side of the pressing part 2 facing the second direction. The first surface 27 is the upper surface of the pressing part 2 in this embodiment, and the second surface 28 is the lower surface of the pressing part 2 in this embodiment. Furthermore, two adjacent buttons 21 are separated by a dividing seam 26. The first surface 27 of the pressing part 2 is provided with a strip groove 251 at the corresponding position of the connecting structure 25. The strip groove 251 extends into the dividing seam 26 to reduce the linkage effect between the two adjacent buttons 21, so that when one of the buttons 21 is pressed, the other buttons 21 will not follow.
[0098] According to embodiments of the present invention, such as Figure 13 and Figure 9As shown, the smart switch 100 also includes a circuit board 5. The panel base 1 covers the bottom shell 3, forming a receiving cavity with the bottom shell 3. The circuit board 5 is housed in the receiving cavity and carries both high-voltage and low-voltage circuits. The bottom shell 3 has mounting holes 31 for inserting mounting screws 32, which are used to mount the bottom shell 3 externally. The panel base 1 has an operating hole 15 at a position corresponding to the mounting hole 31. The nuts of the mounting screws 32 are exposed in the operating hole 15. The button 21 covers the operating hole 15 so that the mounting screws 32 can be operated after the button 21 is removed. This invention integrates the high-voltage and low-voltage circuits onto a single circuit board 5, saving space in the bottom shell 3, making the bottom shell 3 smaller, and allowing it to be placed more conveniently in a junction box, thus improving the installation convenience of the smart switch 100. It also leaves more space in the junction box to accommodate other structures, such as wiring harnesses. However, since the high-voltage and low-voltage circuits are housed on the same circuit board 5, the circuit board 5 cannot be exposed to the outside to prevent electric shock. Therefore, in this invention, the circuit board 5 is enclosed between the panel base 1 and the bottom shell 3, and the panel base 1 does not need to be removed when installing the smart switch 100. In this embodiment, the mounting hole 31 is located within the coverage area of the pressing part 2. When installing the smart switch 100, the user only needs to remove the pressing part 2 to expose the mounting hole 31, and then connect the mounting screw 32 to the wall recess, thereby fixing the smart switch 100 to the wall. The installation process does not require removing the panel base 1, thus protecting the circuit board 5 from damage and avoiding the risk of electric shock from exposed circuit board 5.
[0099] According to embodiments of the present invention, such as Figure 15 , Figure 17 and Figure 19 As shown, since the circuit board provided in this embodiment carries both high-voltage and low-voltage circuits, it needs to be protected from external exposure when powered on. Therefore, in this embodiment, the panel base 1 includes a disassembly structure 16 for detaching the panel base 1 from the bottom shell 3. The disassembly structure 16 is operable to detach the panel base 1 from the bottom shell 3. The disassembly structure 16 is located on the back of the panel base 1, so that when the smart switch 100 is installed on a wall, the disassembly structure 16 is hidden between the panel base 1 and the wall, preventing the user from removing the panel base 1. This avoids the user accidentally removing the panel base 1, exposing the circuit board 5 and posing a risk of electric shock. The disassembly structure 16 can be a clip, screw, or other operable structure that allows the panel base 1 to be detached from the bottom shell 3.
[0100] In one exemplary embodiment, such as Figure 15 and Figure 17 As shown, the disassembly structure 16 includes a second buckle 161, and the bottom shell 3 is provided with a second snap-fit position 33 adapted to the second buckle 161. The second buckle 161 is fastened to the second snap-fit position 33, and the second buckle 161 can be pried to allow the panel base 1 to be detached from the bottom shell 3. The second buckle 161 is integrally formed on the inner side wall of the panel base 1, and the second snap-fit position 33 is provided on the side of the bottom shell 3 away from the panel base 1, so that when the smart switch 100 is installed on the wall, the second buckle 161 is hidden between the panel base 1 and the wall.
[0101] In another exemplary embodiment, such as Figure 19 As shown, the disassembly structure 16 includes a connecting screw 162. The left end of the panel base 1 is fastened to the bottom shell 3, and the right end is provided with a threaded connection hole adapted to the connecting screw 162. The bottom shell 3 is provided with a countersunk hole adapted to the threaded connection hole. The connecting screw 162 passes through the countersunk hole and connects to the threaded connection hole to achieve a detachable connection between the panel base 1 and the bottom shell 3. The countersunk hole is provided on the side of the bottom shell 3 that is in contact with the wall, and the countersunk hole can accommodate the nut of the connecting screw 162. When the smart switch 100 is installed on the wall, the connecting screw 162 is hidden between the panel base 1 and the wall.
[0102] Existing smart switches typically fix the high-voltage circuit board to the base shell. When installed on a wall, the base shell is prone to deformation towards the wall, causing the high-voltage circuit board to move inwards. In this invention, the high-voltage and low-voltage circuits are concentrated on the same circuit board 5, and the detection element 52 is also located on this circuit board 5. If the circuit board 5 moves inwards, the gap between the button 21 and the detection element 52 will increase, resulting in the button 21 failing to trigger the detection element 52. Furthermore, if the base shell 3 deforms significantly, the circuit board 5 can be easily damaged. To solve this problem, according to an embodiment of this invention, such as... Figure 18 and Figure 15 As shown, there is at least one circuit board 5, and each circuit board 5 is fixedly connected to the panel base 1. This ensures that when the bottom shell 3 deforms significantly, it will not directly affect the circuit board 5, thus preventing damage. The bottom shell 3 has mounting holes 31 on opposite sides for external installation. The sides of the bottom shell 3 without mounting holes 31 are connected to the panel base 1. This reduces the deformation of the panel base 1 and the circuit board 5 when the bottom shell 3 deforms during installation, ensuring that the button 21 can accurately trigger the detection element 52 even when the bottom shell 3 is deformed. Figure 18 This is a simplified cross-sectional view of the intelligent switch 100. Figure 18 It contains two diagrams. The first diagram is a structural schematic of the bottom shell 3 before deformation, and the second diagram is a structural schematic of the bottom shell 3 after deformation.
[0103] In a specific embodiment, the bottom shell 3 includes a first side and a second side disposed opposite to each other, and a first end and a second end disposed opposite to each other. The first side, the first end, the second side and the second end are sequentially adjacent to each other surrounding the bottom shell 3. The first side and the second side are respectively provided with the mounting holes 31, and the first end and the second end are respectively connected to the panel base 1. When the bottom shell 3 is installed externally through the mounting hole 31, the first end and the second end of the bottom shell 3 abut against the wall and are supported by the wall. The mounting hole 31 is connected to the junction box by mounting screws 32. If the mounting screws 32 are tightened too much, the first side and the second side of the bottom shell 3 will be driven by the mounting screws 32 and deform downward. At this time, the first end and the second end of the bottom shell 3 change a small range because they are supported by the wall. Since the panel base 1 is connected to the first end and the second end, but not to the first side and the second side, the panel base 1 is minimally affected by the deformation of the bottom shell 3. Since the circuit board 5 is fixedly connected to the panel base 1, the first circuit board 5 is less affected by the deformation of the bottom shell 3, thus ensuring that the first circuit board 5 will not deform downward with the bottom shell 3. This ensures that the relative positional relationship between the button 21 on the panel base 1 and the circuit board 5 is not affected by the deformation of the bottom shell 3, and that the button 21 can accurately trigger the detection element 52 even when the bottom shell 3 is deformed.
[0104] Furthermore, the bottom shell 3 does not provide direct fixing constraints to the circuit board 5, so as to further reduce the impact of deformation of the bottom shell 3 on the circuit board 5.
[0105] Furthermore, such as Figure 15 As shown, the panel base 1 and the bottom shell 3 are detachably connected, so that when the panel base 1 is detached from the bottom shell 3, each of the circuit boards 5 is also detached from the bottom shell 3 along with the panel base 1. Therefore, during assembly, only the circuit boards 5 need to be fixed to the panel base 1, and the bottom shell 3 can be quickly and easily snapped onto the panel base 1 to complete the assembly, improving assembly efficiency. The connection method between the panel base 1 and the bottom shell 3 can be a snap-fit connection, a screw connection, etc. In a specific embodiment, the first end and the second end of the bottom shell 3 are respectively provided with a second snap-fit position 33, and the panel base 1 is provided with a second buckle 161 that cooperates with the second snap-fit position 33. The second buckle 161 is snapped onto the second snap-fit position 33.
[0106] According to embodiments of the present invention, such as Figures 15-16 and Figure 11As shown, there is one circuit board 5. The circuit board 5 is connected to external wires and carries both high-voltage and low-voltage circuits. The circuit board 5 includes a relay 40, a power supply circuit 50, and a detection element 52. The power supply circuit 50 is electrically connected to the external wires and converts AC power to DC power. The detection element 52 is used for detection and control. The relay 40 is electrically connected to the detection element 52 and can switch its on / off state in response to the detection element 52 being controlled. In a specific embodiment, the lower surface of the circuit board 5 has multiple terminals 53. The terminals 53 connect to the neutral wire, the live wire, and the wires controlling the on / off state of the controlled device 200. The power supply circuit 50 and the relay 40 are located on the lower surface of the circuit board 5. The power supply circuit 50 is electrically connected to the terminals 53 and can convert 220V AC power to low-voltage DC power to supply power to the low-voltage circuits. The power supply circuit 50 consists of electronic components such as a transformer, capacitor, inductor, and resistor. Figure 16 This is a bottom view of the circuit board 5. Figure 16 The electronic components within the dashed box constitute the power supply circuit 50. The number of relays 40 is equal to the number of buttons 21. The relays 40 are electrically connected to the terminal block 53 and are used to control the on / off state of the controlled device 200.
[0107] Furthermore, such as Figure 15 and Figure 17 As shown, the terminal block 53 is soldered to the lower surface of the circuit board 5. The bottom shell 3 is provided with a wiring groove 34 at the corresponding position of each terminal block 53. Each terminal block 53 is accommodated in each wiring groove 34. A wiring hole is opened at the bottom of the wiring groove 34. The wire passes through the wiring hole and connects to the terminal block 53. A locking hole is opened on the side of the wiring groove 34. The wiring screw of the terminal block 53 is exposed in the locking hole, so that the user can lock the wiring screw through the locking hole.
[0108] Furthermore, since each terminal 53 must be accommodated in each terminal slot 34, and the position of the locking hole must correspond to the terminal screw, the relative positional accuracy between the terminal 53 and the terminal slot 34 requires high precision. Therefore, as follows: Figure 16 and Figure 15 As shown, in this embodiment, a long strip-shaped first positioning hole 54 is provided between each wiring terminal 53, and a long strip-shaped positioning rib 341 is provided between each wiring groove 34 of the bottom shell 3. The positioning rib 341 is inserted into the first positioning hole 54 to position the bottom shell 3 and the circuit board 5. The positioning rib 341 extends from bottom to top so that when the bottom shell 3 deforms downward, the positioning rib 341 will not affect the circuit board 5.
[0109] Furthermore, such as Figure 9 and Figure 11As shown, the detection element 52 is disposed on the side of the circuit board 5 facing the button 21. A trigger hole 17 is provided on the panel base 1 at the corresponding position of the detection element 52. A trigger post 211 is provided on the button 21 facing the detection element 52, and the trigger post 211 passes through the trigger hole 17 and abuts against the detection element 52. The number of detection elements 52, trigger posts 211, and trigger holes 17 corresponds to the number of buttons 21.
[0110] According to embodiments of the present invention, such as Figure 15 and Figure 18 As shown, the circuit board 5 is fixedly connected to the panel base 1 by a plurality of fixing screws 554. The bottom shell 3 is provided with a relief recess 35 at the corresponding position of the fixing screws 554. The relief recess 35 is used to accommodate the nuts of the fixing screws 554, so that the circuit board 5 can be close to the bottom shell 3, thereby reducing the thickness of the panel base. Here, "close" can be understood as the distance between the circuit board 5 and the bottom shell 3 being within 2mm. In one embodiment, the circuit board 5 is attached to the upper surface of the bottom shell 3.
[0111] Furthermore, such as Figure 11 As shown, the panel base 1 is provided with two second positioning posts 181, multiple second threaded connection holes 182, and three square protrusions 183 facing the circuit board 5. The circuit board 5 is provided with a second positioning hole 551, a second connecting through hole 552, and a square hole 553 corresponding to each other. The second positioning posts 181 are inserted into the second positioning holes 551 to position the circuit board 5 and the panel base 1. The fixing screw 554 passes through the second connecting through hole 552 and connects to the second threaded connection hole 182 to fix the circuit board 5 to the panel base 1. The square hole 553 is used to accommodate the square protrusion 183. The square protrusion 183 is provided with a first snap-fit position 13 and is hollow, providing space for the movable snap-fit structure 243 to move.
[0112] According to embodiments of the present invention, such as Figure 15 and Figure 16 As shown, a wireless communication module 56 is provided on the side of the circuit board 5 facing away from the panel substrate 1. No copper foil is laid on the circuit board 5 at the position corresponding to the wireless communication module 56, so that the wireless signal can pass through the circuit board 5 and the circuit board 5 can avoid shielding the wireless signal.
[0113] Since the circuit board 5 of this invention carries a high-voltage circuit, there is a certain probability that the high voltage on the circuit board 5 will be transmitted along the surface of the insulating material to the mounting screw 32. Therefore, sufficient creepage distance needs to be designed to prevent current leakage from the circuit board 5 to the mounting screw 32. Creepage distance is the shortest spatial distance measured along the surface of the insulating material between two conductive components. According to the embodiments of this invention, such as... Figure 15 and Figure 13 As shown, the bottom shell 3 has an isolation wall 36 protruding around the mounting hole 31 towards the panel base 1. The circuit board 5 is disposed on the outside of the isolation wall 36. The isolation wall 36 surrounds the mounting hole 31. The current on the circuit board 5 needs to cross the isolation wall 36 to reach the mounting screw 32, thereby increasing the creepage distance between the circuit board 5 and the mounting screw 32 and preventing the user from touching the mounting screw 32 and getting an electric shock.
[0114] Existing switches with displays typically place the display between a panel base and a transparent cover. The panel base limits the sides of the display, and the transparent cover covers the top surface of the display to secure it. The transparent cover is also adhered to both the panel base and the display. When the display needs to be removed, the transparent cover must be removed first, which is difficult. Furthermore, when there are multiple displays, this method of securing them makes it difficult to remove one display individually without affecting the others, making it unsuitable for the smart switch with multiple displays provided by this invention. Therefore, according to an embodiment of this invention, such as... Figure 14 , Figure 11 and Figure 12As shown, a circuit board 5 is provided on the side of the panel base 1 away from the pressing part 2. The display screen 101 is disposed between the panel base 1 and the circuit board 5 and is electrically connected to the circuit board 5. The display screen 101 has a third surface 1011 away from the circuit board 5. The side of the display screen 101 and the third surface 1011 abut against the panel base 1, so that the display screen 101 is limited by the panel base 1. A display area 1012 is provided on the third surface 1011. A display through hole 191 is provided on the panel base 1 at the position directly opposite to the display area 1012. A transparent cover plate 4 is provided on the side of the panel base 1 away from the circuit board 5. The transparent cover plate 4 covers the display through hole 191. The content displayed in the display area 1012 is displayed to the outside through the display through hole 191 and the transparent cover plate 4. The display screen 101 of this utility model embodiment is installed into the panel base 1 from the side of the panel base 1 away from the transparent cover plate 4 and is confined between the panel base 1 and the circuit board 5. When disassembling the display screen 101, only the circuit board 5 needs to be removed to disassemble each display screen 101 individually. The disassembly of the display screen 101 will not affect the assembly state of other display screens 101, which is more suitable for the structure of multiple display screens 101 in this utility model embodiment. Moreover, the transparent cover plate 4 does not need to be removed during the disassembly process, which reduces the difficulty of disassembly and assembly.
[0115] The statement that the display screen 101 abuts against the panel substrate 1 can be understood as the display screen 101 directly abutting against the panel substrate 1 or indirectly abutting against the panel substrate 1 through other structures. In one embodiment, such as... Figure 14 As shown, a first double-sided adhesive (not shown) is provided between the display screen 101 and the panel substrate 1. The display screen 101 is adhered to the panel substrate 1 by the first double-sided adhesive. The first double-sided adhesive covers the periphery of the third surface 1011, so that the third surface 1011 is sealed to the lower side of the display through hole 191. Additionally, as... Figure 20 As shown, the transparent cover plate 4 is attached to the upper side of the display through hole 191 with adhesive 41, so that the upper and lower sides of the display through hole 191 are sealed by the transparent cover plate 4 and the display screen 101 respectively, thereby preventing dust and moisture from entering between the transparent cover plate 4 and the display screen 101 and affecting the display effect.
[0116] Furthermore, such as Figure 12 As shown, the panel base 1 has abutment ribs 192 around the sides of the display screen 101. The abutment ribs 192 abut against the sides of the display screen 101 to limit the sides of the display screen 101.
[0117] Furthermore, such as Figure 11As shown, the circuit board 5 is fixedly connected to the panel base 1 by a plurality of fixing screws 554 to facilitate the installation and removal of the circuit board 5, thereby facilitating the installation and removal of the display screen 101. The display screen 101 and the circuit board 5 are connected by a ribbon cable 1013 to disconnect the display screen 101 from the circuit board 5 when it is disassembled. This improves the efficiency of replacing the display screen 101.
[0118] According to embodiments of the present invention, such as Figure 14 As shown, the circuit board 5 is provided with a ribbon cable connection terminal 57, and the display screen 101 is provided with a ribbon cable 1013 facing the third direction. The ribbon cable 1013 is bent and inserted into the ribbon cable connection terminal 57. The third direction is the direction from the pressing end 23 of the pressing part 2 towards the connecting end 22. The third direction has already been... Figure 14 The present invention has been approved. In this embodiment, the ribbon cable 1013 of the display screen 101 is oriented away from the button 21, so that the distance between the display screen 101 and the button 21 is closer and the indication effect is better; and it avoids the ribbon cable 1013 and the pressing part 2 from stacking in the thickness direction, which reduces the thickness of the smart switch 100 and avoids the movement of the pressing part 2 causing the ribbon cable 1013 to move and be damaged.
[0119] Furthermore, such as Figure 14 and Figure 11 As shown, a supporting foam 59 is provided between the display screen 101 and the circuit board 5, providing support for the display screen 101. The upper end of the supporting foam 59 abuts against and is attached to the display screen 101, while the lower end abuts against the circuit board 5. The supporting foam 59 is in a compressed state, thereby providing support for the display screen 101 and making the connection between the display screen 101 and the panel substrate 1 more stable. The ribbon cable connection terminal 57 is located below the supporting foam 59 and is covered by the supporting foam 59, making the connection between the ribbon cable 1013 and the ribbon cable connection terminal 57 more stable.
[0120] According to embodiments of the present invention, such as Figure 20 and Figure 5 As shown, a light-shielding layer 42 is provided on the side of the transparent cover plate 4 facing the panel substrate 1; a display window 421 is opened on the light-shielding layer 42 directly opposite the display area 1012, and the content displayed in the display area 1012 is displayed to the outside through the display window 421; wherein, the light-shielding layer 42 is specifically a black coating, which is printed on the back of the transparent cover plate 4 by screen printing. The function of the light-shielding layer 42 is to cover the internal structure and improve the aesthetics. Since the circuit board 5 is equipped with high-voltage circuits and low-voltage circuits, the display screen 101 is considered to be a live body, and the creepage distance between the display screen 101 and the outer surface of the switch must be greater than 2mm to avoid electric shock to the user. Therefore, as Figure 14As shown, a preset gap is provided between the transparent cover plate 4 and the display screen 101, thereby increasing the creepage distance between the display screen 101 and the upper surface of the transparent cover plate 4. In one embodiment, the preset gap is 1.2 mm, and the thickness of the transparent cover plate 4 is 2 mm.
[0121] However, due to the existence of the preset gap, when the smart switch 100 is installed on the wall, the upper part of the display area 1012 will be partially blocked by the light-shielding layer 42 (e.g., Figure 21 As shown, since the smart switch 100 is installed on the wall at a position generally lower than eye level, the viewing angle of the human eye when looking at the display screen 101 is a downward tilted angle, causing the upper edge of the display window 421 to obscure a portion of the display area 1012. Therefore, a blank area is provided at one end of the display area 1012 facing the fourth direction. Figure 21 (Not shown in the image), no content is displayed in the blank area to avoid the content being blocked by the light-shielding layer 42; wherein, the fourth direction is the same as the vertical upward direction when the smart switch 100 is installed on the wall, in this embodiment, the fourth direction is the same as the third direction, and the fourth direction has been... Figure 21 The blank area is marked as the upper horizontal area of the display area 1012. Further, as... Figure 21 As shown, the display window 421 is positioned directly opposite the display area 1012. The size of the display window 421 is slightly larger than the size of the display area 1012 to reduce the amount of obstruction of the display area 1012 by the display window 421.
[0122] According to embodiments of the present invention, such as Figure 6 As shown, the transparent cover plate 4 and the connecting end 22 of the pressing part 2 are arranged side by side, and the side of the transparent cover plate 4 facing the fifth direction is flush with the side of the pressing part 2 facing the fifth direction. In one embodiment, when the pressing part 2 is not pressed, both the transparent cover plate 4 and the pressing part 2 are... Figure 6 The horizontal state in the middle.
[0123] According to embodiments of the present invention, such as Figure 11 and Figure 20As shown, the circuit board 5 is equipped with an infrared detection device 20, which includes an infrared emitting unit 201 for emitting a detection wave and an infrared receiving unit 202 for triggering the display screen 101 upon receiving the detection wave. The infrared detection device 20 detects the distance between an external object and the smart switch 100. When the distance is sufficiently close, the display screen 101 is triggered. Specifically, the detection wave emitted by the infrared emitting unit 201 is reflected by the external object and transmitted to the infrared receiving unit 202. The closer the external object is to the infrared receiving unit 202, the stronger the intensity of the reflected detection wave detected by the infrared receiving unit 202. When the intensity of the detection wave detected by the infrared receiving unit 202 is greater than a threshold, the smart switch 100 determines that the distance between the external object and the smart switch 100 is less than a predetermined distance, and then controls the display screen 101 to light up. The detection wave can be an infrared light wave or other electromagnetic waves. Furthermore, the transparent cover plate 4 covers the infrared emitting unit 201 and the infrared receiving unit 202, and the detection wave passes through the transparent cover plate 4 for external detection.
[0124] The inventors discovered that the detection wave emitted by the infrared emitting unit 201 can easily be transmitted from the inside of the smart switch 100 to the infrared receiving unit through two erroneous paths, causing the infrared detection device 20 to misjudge. One path is that the detection wave is transmitted to the infrared receiving unit 202 via total internal reflection inside the transparent cover plate 4; the other is that the detection wave passes through the gap between the panel substrate 1 and the circuit board 5 to the infrared receiving unit 202, or, when the panel substrate 1 is thin and light-colored, the detection wave directly penetrates the panel substrate 1 to the infrared receiving unit 202. To reduce these two erroneous transmission paths, this invention adopts the following solution: Figure 20 , Figure 11 and Figure 6 As shown, the infrared emitting unit 201 includes an infrared LED 2012, and the infrared receiving unit 202 includes an infrared receiver 2021. At least one display screen 101 is disposed between the infrared LED 2012 and the infrared receiver 2021, thereby increasing the distance between them and reducing the total internal reflection of the detection wave inside the transparent cover plate 4. A shielding member 58 is arranged around the infrared LED 2012 to block the detection wave from the side of the LED 2012, thus reducing the transmission of the detection wave through the gap between the panel substrate 1 and the circuit board 5 or through the panel substrate 1 to the infrared receiver 202. These two methods reduce the transmission of the detection wave inside the smart switch 100, preventing false detection by the infrared detection device 20.
[0125] It is worth mentioning that increasing the distance between the infrared receiver 2021 and the infrared LED 2012 can, to a certain extent, prevent small objects such as flies and mosquitoes from accidentally triggering the infrared detection device 20. Specifically, when flies and mosquitoes rest on the switch surface, because of their small size, their bodies can only cover either the infrared LED 2012 or the infrared receiver 2021, which is insufficient to trigger the infrared detection device 20.
[0126] In one embodiment, such as Figure 20 As shown, there are three display screens 101, which are arranged at intervals along the first direction. The infrared light-emitting tube 2012 is disposed between the left display screen 101 and the middle display screen 101, and the infrared receiver 2021 is disposed between the middle display screen 101 and the right display screen 101.
[0127] Furthermore, such as Figure 6 , Figure 11 and Figure 20 As shown, the shielding member 58 is a black annular foam surrounding the infrared LED 2012. The upper end of the annular foam abuts against the adhesive 41 of the transparent cover plate 4, and the lower end abuts against the circuit board 5, thereby blocking the detection wave from passing through the annular foam from the side. It is worth noting that, since the annular foam is a flexible material, it can fit tightly against the circuit board 5, preventing the detection wave from propagating out through the gap between the annular foam and the circuit board 5. Furthermore, the panel substrate 1 has a transmitting through-hole 193 and a receiving through-hole 194 at corresponding positions of the annular foam and the infrared receiver 2021. The transmitting through-hole 193 accommodates the annular foam and limits its position, while the receiving through-hole 194 accommodates the infrared receiver 2021.
[0128] Furthermore, such as Figure 20 and Figure 5As shown, the light-shielding layer 42 has an emission window 422 directly opposite the infrared LED 2012, and a receiving window 423 directly opposite the infrared receiver 2021. The infrared receiver 2021 receives external detection waves through the receiving window 423; the infrared LED 2012 emits detection waves through the emission window 422, and the emission angle of the detection waves is limited to less than 90° by the emission window 422. When the distance between the infrared LED 2012 and the light-shielding layer 42 is fixed, the smaller the size of the emission window 422, the smaller the emission angle of the detection waves, and the smaller the detection angle of the infrared detection device 20. When the size of the emission window 422 is constant, the larger the distance between the infrared LED 2012 and the transparent cover plate 4, the smaller the emission angle of the detection waves, and the smaller the detection angle of the infrared detection device 20. By controlling the size of the emission window 422 and the distance between the infrared LED 2012 and the transparent cover plate 4, the detection angle of the infrared detection device 20 can be accurately controlled. In this embodiment of the invention, the detection angle of the infrared detection device 20 is controlled to be less than 90°. This is because if the detection angle is too large, the infrared detection device 20 is easily triggered falsely. Conversely, if the detection angle is too small, the smart switch 100 may not trigger when the user approaches it from the side. Therefore, the inventors, through experimental verification, controlled the detection angle to be between 30° and 60° to achieve a suitable triggering range.
[0129] Furthermore, such as Figure 20 As shown, the adhesive 41 of the transparent cover plate 4 has a first adhesive hole 411, a second adhesive hole 412, and a third adhesive hole 413 respectively at the positions directly opposite the display window 421, the transmitting window 422, and the receiving window 423. The size of the first adhesive hole 411, the second adhesive hole 412, and the third adhesive hole 413 is larger than the size of the display window 421, the transmitting window 422, and the receiving window 423.
[0130] In another embodiment, such as Figure 22 As shown, this embodiment is similar to Figures 1-21 The difference in this embodiment is that the engagement between the plug-in structure 241 and the plug-in position 11 is relatively loose. When the button 21 is pressed, the pressing part 2 will pivot based on the first pivot 121, and the plug-in structure 241 no longer provides a restoring force. A restoring foam 29 is provided between each button 21 and the panel base 1, and the restoring force is provided through the restoring foam 29. Compared with a spring, foam has the characteristic of slow rebound. Using foam to provide the restoring force can make the pressing feel of the button 21 have a damped feel, making the pressing feel more advanced. Furthermore, a foam mounting position 291 is provided on the lower surface of the button 21, and the restoring foam 29 is attached to the foam mounting position 291. Furthermore, in the first direction, reinforcing ribs are provided on both sides of each button 21 to enhance the rigidity of the button 21.
[0131] Furthermore, such as Figure 22 As shown, each button 21 has a thinning slope 261 on the side adjacent to other buttons 21. The thinning slope 261 is used to reduce the thickness of the edge of the button 21, making the button 21 thinner near the connecting structure 25, thereby reducing the linkage effect between the buttons 21, that is, the movement of one button 21 will not drive the movement of other adjacent buttons 21. In addition, the thinning slope 261 on the button 21 can also increase the width of the injection mold at this part, thereby making the injection mold corresponding to this part less prone to damage. Specifically, if the button 21 does not have the thinning slope 261, the injection mold at the position corresponding to the dividing seam 26 will be a thin strip, which is easy to damage. The thinning slope 261 reduces the thickness of the button 21 at the position corresponding to the dividing seam 26, and the injection mold at this position becomes wider, thereby increasing the strength of the injection mold.
[0132] In another embodiment, such as Figure 23 As shown in the figure, the transparent cover 4 is not displayed. This embodiment is a two-button version of the smart switch 100. This embodiment is similar to... Figures 1-21 The difference in this embodiment is that there are two buttons 21, and correspondingly, there are two displays 101, two relays 40, two detection elements 52, two trigger holes 17, and two trigger posts 211. The infrared LED 2012 is positioned between the two displays 101, and the infrared receiver 2021 is positioned on the right side of the right display 101, increasing the distance between the infrared LED 2012 and the infrared receiver 2021. This reduces the total internal reflection of the detection wave inside the transparent cover 4, preventing misjudgment by the infrared detection device 20. The displays 101, infrared LED 2012, and infrared receiver 2021 are arranged side-by-side along a first direction. The panel substrate 1 has display through holes 191, emission through holes 193, and reception through holes 194 respectively at the corresponding positions of the display area 1012 of the displays 101, the infrared LED 2012, and the infrared receiver 2021. The positions of the display window 421, the transmitting window 422, and the receiving window 423 on the light-shielding layer 42 correspond to the positions of the display through-hole 191, the transmitting through-hole 193, and the receiving through-hole 194. Each button 21 is provided with one of the aforementioned movable latching structures 243. The number and position of the first latching positions 13 on the panel base 1 are the same as those of the three-button version of the smart switch 100, both being three. The first latching positions 13 on the left and right sides of the panel base 1 are respectively latched into the movable latching structures 243 of the two buttons 21.
[0133] In another embodiment, such as Figure 24 As shown in the figure, the transparent cover 4 is not displayed; this embodiment is a single-button version of the smart switch 100. This embodiment is similar to... Figures 1-21The difference in this embodiment is that there is only one button 21, and correspondingly, there is one display screen 101, one relay 40, one detection element 52, one trigger hole 17, and one trigger post 211. The infrared LED 2012 is located on the left side of the display screen 101, and the infrared receiver 2021 is located on the right side of the display screen 101. This increases the distance between the infrared LED 2012 and the infrared receiver 2021, thereby reducing the total internal reflection of the detection wave inside the transparent cover plate 4 and preventing misjudgment by the infrared detection device 20. The display screen 101, the infrared LED 2012, and the infrared receiver 2021 are arranged side-by-side along a first direction. The panel substrate 1 has display through holes 191, emission through holes 193, and reception through holes 194 respectively at the corresponding positions of the display area 1012 of the display screen 101, the infrared LED 2012, and the infrared receiver 2021. The positions of the display window 421, the transmitting window 422, and the receiving window 423 on the light-shielding layer 42 correspond to the positions of the display through-hole 191, the transmitting through-hole 193, and the receiving through-hole 194. The button 21 is provided with two of the aforementioned movable latching structures 243. The number and position of the first latching positions 13 on the panel base 1 are the same as those of the three-button version of the smart switch 100, both being three. The first latching positions 13 on the left and right sides of the panel base 1 are respectively latched onto the two movable latching structures 243 of the button 21.
