The name of the invention in the original application is The application is for: smart switch. The application date of the original application is: December 16, 2023. Technical Field

[0002] The present application relates to the field of switches, and in particular to an intelligent switch. Background Art

[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 the triggering device of smart homes, smart switches play a very critical role in the entire system. More and more users choose smart switches to control indoor electrical equipment when decorating.

[0004] For multi-button smart switches, users are easily confused about the corresponding functions of each button. Most existing smart switches are pre-printed with text or patterns on the buttons to indicate the button functions. If the function corresponding to a button is changed, the button needs to be replaced simultaneously, which brings inconvenience to the user and causes waste. Utility Model Content

[0005] One purpose of the present utility model is to provide an intelligent switch, in which the function information of each button is displayed separately through multiple independent display screens. The user can change the display content of the display screen to adapt to the change of the button function, which solves the problem in the prior art that it is necessary to change the pattern or text by replacing the button. The advantage of using multiple display screens over using a whole display screen is that the effective utilization rate of the display area of ​​a single display screen is improved, the blank area is reduced, and when one of the display screens is damaged, the display screen can be replaced separately, saving maintenance costs.

[0006] Another object of the present invention is to provide an intelligent switch, in which the ends of each button are connected to each other through a connecting end, so that the position correspondence between the button and the display screen is more accurate; at the same time, because the ends of each button are connected, the buttons can provide a reset force to each other, without the need for an additional reset structure, so that the structure is simplified; and, the connection of each button prevents the button from shaking or being loose, thereby improving the pressing feel.

[0007] Another object of the present invention is to provide an intelligent switch, in which the pressing portion adopts a scheme in which a plug-in structure and an abutment structure are matched, so that the pressing portion can be disassembled as a whole from the panel base without removing each button one by one, thereby avoiding breaking off the connection ends connecting the buttons. Therefore, the pressing portion disassembly scheme provided in this embodiment is more suitable for the continuous button structure of the present invention.

[0008] Another object of the present invention is to provide an intelligent switch, wherein when the pressing end is pressed, the pressing end moves with the supporting limit structure as a fulcrum, and the plug-in position gives the plug-in structure an abutment force toward the second direction, so that the pressing end generates a reset force, and thus the button does not require an additional reset structure, and the structure is simplified.

[0009] Another object of the present utility model is to provide an intelligent switch, in which the function of the snap-fitting and rotating structure is to improve the connection stability between the two sides of the pressing part and the panel base. When the button is pressed, the snap-fitting and rotating structure can also provide supporting force and limiting force, making the pressing movement of the button more stable and reliable; and when disassembling the pressing part, if the movable snap-fitting structure is disengaged from the panel base, the snap-fitting and rotating structure can provide auxiliary snap-fitting force to prevent the pressing part from falling.

[0010] Another object of the present invention is to provide an intelligent switch, in which the installation and removal processes of the pressing portion are relatively simple and convenient because the opening direction of the card interface is an inclined direction, and the card rotation structure cooperates with the abutment structure, so that the pressing portion can be more conveniently removed and installed as a whole, avoiding damage to the connection end by removing each button one by one.

[0011] Another object of the present invention is to provide an intelligent switch, wherein a connecting structure is recessed in a first surface of a pressing portion so that when one of the buttons is pressed, the other buttons do not follow the movement; and the connecting structure protrudes from a second surface of the pressing portion to enhance the strength of the connection between the buttons.

[0012] Another object of the present invention is to provide an intelligent switch, wherein when disassembling a display screen, only the circuit board needs to be removed, and each display screen can be removed separately. The display screen will not affect the assembly state of other display screens during the disassembly process, which is more suitable for the structure of multiple display screens in the embodiment of the present invention; and there is no need to remove the transparent cover during the disassembly process, which reduces the difficulty of disassembly and assembly.

[0013] Another object of the present invention is to provide an intelligent switch, in which the cable is arranged in a third direction, so that the distance between the display screen and the button is closer, and the indication effect is better; and the cable and the pressing portion are prevented from overlapping in the thickness direction, thereby reducing the thickness of the intelligent switch and preventing the cable from being damaged by the movement of the pressing portion.

[0014] Another object of the present invention is to provide an intelligent switch, wherein a preset gap is provided between the transparent cover and the display screen, so that the creepage distance between the display screen and the upper surface of the transparent cover is increased.

[0015] Another object of the present utility model is to provide an intelligent switch, wherein 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 prevent the displayed content from being blocked by the shading layer.

[0016] Another object of the present invention is to provide an intelligent switch in which at least one display screen is disposed between an infrared light-emitting tube and an infrared receiving head, thereby increasing the distance between the infrared receiving head and the infrared light-emitting tube, thereby reducing the total reflection of the detection wave within the transparent cover plate. A shielding member is disposed around the infrared light-emitting tube to block the detection wave from the side of the infrared light-emitting tube, thereby reducing the detection wave from passing through the gap between the panel substrate and the circuit board or penetrating the panel substrate to the infrared receiving unit. These two solutions reduce the transmission of the detection wave within the intelligent switch, thereby preventing misjudgments by the infrared detection device.

For example, it can mean fixed connection, detachable connection, or integration; it can mean mechanical connection, electrical connection, or mutual communication; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0079] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0080] At present, most of the button-type smart switches are pre-printed with text or patterns on the buttons to indicate the button function. If the user changes the function of the button, the button needs to be replaced at the same time, which brings inconvenience to the user and causes waste. To solve this problem, please refer to Figure 1-Figure 24 , the present invention provides a smart switch 100 is specifically explained. Figure 1-Figure 5As shown, the smart switch 100 includes a panel base 1, a pressing portion 2 and a display device 10; the pressing portion 2 is connected to the panel base 1, and the pressing portion 2 includes a plurality of buttons 21; the display device 10 includes a plurality of display screens 101 corresponding to each of the buttons 21, and each of the display screens 101 is provided on the panel base 1 for displaying the button information of the corresponding button 21; the smart switch 100 provided by the present invention can display the corresponding information of each button 21 through the display screen 101, and the user can change the display content of the display screen 101 to adapt to the change of the button function, which solves the problem in the prior art of needing to change the pattern or text by replacing the button 21. Among them, the one-to-one correspondence between the display screen 101 and the button 21 can be understood as that the number of the display screens 101 is equal to the number of the buttons 21, and the position corresponds to the position of the button 21. For example, each display screen 101 can be provided near the end of each button 21. The advantage of using multiple independent display screens 101 compared to using a whole display screen 101 is that the effective utilization rate of the display area of ​​a single display screen 101 is improved, the blank area is reduced, and when one of the display screens 101 is damaged, the display screen 101 can be replaced separately, saving maintenance costs.

[0081] In addition, if Figure 1-Figure 5 As shown, one end of each button 21 of the intelligent switch 100 provided by the present invention is connected to each other to form the connecting end 22 of the pressing portion 2, and the other end of each button 21 away from the one end is separated from each other to form the pressing end 23 of the pressing portion 2, so that when one of the buttons 21 is pressed, the other buttons 21 will not follow the movement, and each button 21 provides a reset force to each other through the connecting end 22, and each display screen 101 is arranged near the connecting end 22. Among them, the connection between one end of each button 21 can be an integral connection, or the buttons 21 can be fixedly connected as a whole by a fixing plate, or other forms of connection. The reset force provided by each button 21 can be understood as the ends of each button 21 are connected through the connecting end 22. When one button 21 is pressed, the button 21 drives the connecting end 22 to generate a movement trend, while the connecting end 22 remains stationary under the connection action of the other buttons 21, thereby causing the connecting end 22 and the pressed button 21 to deform, thereby generating a reset force. The display screens 101 being disposed near the connection end 22 can be understood as each display screen 101 being disposed near the end of each button 21 in a one-to-one correspondence.

[0082] In the intelligent switch 100 provided by the present invention, the ends of the buttons 21 are interconnected, so that the spacing between the buttons 21 remains consistent, thereby making the positional correspondence between the buttons 21 and the display screen 101 more accurate. At the same time, since the ends of the buttons 21 are connected, the buttons 21 can provide a mutual reset force, eliminating the need for an additional reset structure and simplifying the structure. Furthermore, the connection of the buttons 21 prevents the buttons 21 from shaking or feeling loose, thereby improving the pressing feel.

[0083] According to the embodiment of the present utility model, Figure 9 and Figure 13 As shown, the smart switch 100 further includes a bottom shell 3, which is provided with a mounting hole 31 for external installation, and the pressing portion 2 covers the mounting hole 31. When installing the smart switch 100, the user only needs to remove the pressing portion 2 to expose the mounting hole 31, and then insert the mounting screw 32 through the mounting hole 31 to connect it to the hidden box on the wall, thereby fixing the smart switch 100 to the wall. The panel base 1 does not need to be removed during the installation process, which protects the internal circuit board 5 and avoids the risk of the circuit board 5 falling and being damaged after the panel base 1 is removed.

[0084] Since the smart switch 100 provided by the present invention requires the buttons 21 to be disassembled before being installed externally, the buttons 21 need to be easy to disassemble and assemble, and the buttons 21 cannot be disassembled one by one during disassembly and assembly to avoid the connection ends 22 connecting the buttons 21 being broken. Based on this, the embodiment of the present invention provides a row of buttons 21 that are easy to disassemble and assemble, including a plug-in structure 241, an abutment structure 242, and a movable clamping structure 243. These three structures cooperate with each other to achieve the effect of easy disassembly and assembly of the buttons 21. Figure 6 、 Figure 3 and Figure 9 As shown, the connecting end 22 of the pressing portion 2 is provided with the plug-in structure 241, the panel base 1 is provided with a plug-in position 11, and the plug-in structure 241 is plugged into the plug-in position 11 so as to be restricted by the plug-in position 11 to move toward a fifth direction, the fifth direction being opposite to the direction in which the button 21 is pressed, wherein, Figure 5 is a top view of the smart switch 100, Figure 6 for Figure 5 In the AA step cross-sectional view, it should be noted that the plug structure 241, the abutment structure 242 and the movable clamping structure 243 are not on the same vertical plane (by Figure 3 As can be seen), Figure 6 The three are concentrated on the same cross section by step section, so that the structure can be displayed more intuitively. Figure 6 The vertical upward direction, the fifth direction is already in Figure 6The plug-in structure 241 can be a tongue, a pin, a plate or other plug-in structure. The plug-in direction of the plug-in structure 241 can be Figure 6 The horizontal direction may be an upwardly inclined direction or a downwardly inclined direction, and the plug-in position 11 may abut against the upper surface of the plug-in structure 241 during the movement of the button 21 to limit the movement of the plug-in structure 241 toward the fifth direction.

[0085] The connecting end 22 of the pressing portion 2 is provided with the abutting structure 242 facing the second direction. The abutting structure 242 is provided between the plug-in 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, the second direction is already Figure 6 Marked in the middle; the panel base body 1 has a support and limiting structure 12 at the position corresponding to the abutment structure 242, the abutment structure 242 abuts against the support and limiting structure 12, and the support and limiting structure 12 can limit the plug-in structure 241 from being separated from the plug-in position 11, wherein, when the abutment structure 242 abuts against the support and limiting structure 12, the two cooperate to limit the horizontal movement of the button 21, thereby limiting the plug-in structure 241 from being separated from the plug-in position 11 to the right. Figure 7 The figure shows a schematic diagram of the pressing end 23 of the pressing portion 2 when it is subjected to a pressing force. When the pressing end 23 is pressed, the pressing end 23 moves with the support and limiting structure 12 as a fulcrum. For example, the button 21 can pivot with the support and limiting structure 12 as a fulcrum, thereby driving the pressing end 23 to move; or the button 21 can deform with the support and limiting structure 12 as a fulcrum, and the deformation of the button 21 drives the pressing end 23 to move downward, thereby triggering the detection member 52. Each button 21 is provided with a movable clamping structure 243 near the pressing end 23 facing the second direction. The movable clamping structure 243 is clamped to the panel base 1 and can limit the pressing end 23 of the button 21 from separating from the panel base 1 in the fifth direction. The movable clamping structure 243 can also move in the second direction.

[0086] like Figure 8 As shown, Figure 8 for Figure 6In the schematic diagram of the disassembly process of the pressing portion 2 in FIG, when the pressing portion 2 is disassembled from the panel base 1, the user can first bend the pressing end 23 upward to disengage the movable engaging structures 243 from the panel base 1. The pressing portion 2 can then rotate counterclockwise based on the plug-in structure 241 as a whole. When the rotation angle reaches a certain value, the abutment structure 242 disengages from the support and limiting structure 12, and the pressing portion 2 loses the restriction of the support and limiting structure 12, allowing the plug-in structure 241 to disengage from the plug-in position 11 to the right. The entire disassembly process is simple and quick, which is suitable for the characteristics of the smart switch 100 that the pressing portion 2 needs to be disassembled before external installation. Moreover, compared with the prior art in which each button 21 is provided with a hole for rotational connection with the panel base 1, this embodiment adopts a solution in which the plug-in structure 241 and the abutment structure 242 cooperate with each other, so that the pressing portion 2 can be disassembled as a whole from the panel base 1 without disassembling each button 21 one by one, thereby avoiding the connection ends 22 connecting each button 21 from being broken. Therefore, the pressing portion 2 disassembly solution provided in this embodiment is more suitable for the structure of the continuous button 21 of the present invention.

[0087] Correspondingly, the installation process of the pressing part 2 is opposite to the removal process, such as Figure 8 As shown, when the pressing portion 2 is installed on the panel base 1, the plug structure 241 can be first inserted into the plug position 11 at an angle toward the lower left. Then, the pressing portion 2 is rotated clockwise based on the plug structure 241 so that the abutment structure 242 abuts the support and limit structure 12. Finally, the pressing end 23 is pressed downward to engage the movable engaging structure 243 with the panel base 1, completing the installation. The entire installation process is quick and convenient, which is suitable for the characteristic of the smart switch 100 of the present invention that the pressing portion 2 needs to be installed on the panel base 1 after it is installed on the wall.

[0088] Furthermore, if Figure 8 As shown, during the installation and removal of the pressing portion 2, when the pressing portion 2 is tilted, the left end of the pressing portion 2 abuts against the transparent cover 4. In order to ensure that the pressing portion 2 can be smoothly installed and removed, as shown in FIG. Figure 6 As shown, a certain gap is set between the left end of the pressing part 2 and the transparent cover 4. The gap reserves space for the pressing part 2 to rotate, so that during the installation and disassembly of the pressing part 2, when the pressing part 2 is tilted, the transparent cover 4 will not interfere with the pressing part 2.

[0089] According to the embodiment of the present utility model, Figure 7 and Figure 6As shown, the plug-in position 11 abuts against the side of the plug-in structure 241 facing the fifth direction. When the pressing end 23 is pressed, the pressing end 23 moves with the support and limiting structure 12 as the fulcrum. The plug-in position 11 applies a contact force to the plug-in structure 241 in the second direction, so that the pressing end 23 generates a reset force. The pressing portion 2 is equivalent to a seesaw structure with the support and limiting structure 12 as the fulcrum. The plug-in position 11 restricts the left end of the pressing portion 2 from moving upward through the plug-in structure 241. When the pressing end 23 at the right end of the pressing portion 2 is pressed, the pressing end 23 moves downward. Since the left end of the pressing portion 2 is restricted and cannot move upward, the pressed key 21 is bent and deformed, while the other keys 21 that are not pressed remain in their initial state. The deformation of the keys 21 generates a reset force, which is set as the first reset force. Secondly, because the buttons 21 are interconnected via the connecting ends 22, they can also provide a mutual restoring force, which is defined as the second restoring force. Furthermore, the pressure exerted by the buttons 21 against the detection member 52 generates a reaction force on the buttons 21, which is defined as the third restoring force. When the pressing force is removed, the pressed buttons 21 are reset by the combined action of the first, second, and third restoring forces, eliminating the need for an additional restoring mechanism for the buttons 21 and simplifying their 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 a tactile switch.

[0091] Furthermore, if Figure 6 As shown, the detection member 52 is provided on one side of the circuit board 5 facing the panel base 1, and the button 21 is provided with a trigger column 211 facing the detection member 52. The button 21 triggers the detection member 52 through the trigger column 211. When the button 21 is not pressed, the detection member 52 is still pressed by the trigger column 211 to generate a small amount of compression. This compression is not enough to trigger the detection member 52, but it can provide a pre-tightening force for the button 21, so that the button 21 will not be loose and the pressing feel will be tighter. Moreover, this compression can keep the trigger column 211 and the detection member 52 in abutment state, eliminating the gap between the trigger column 211 and the detection member 52, thereby eliminating the empty travel of the button 21 and improving the trigger sensitivity of the button 21. Further, as Figure 3 、 Figure 6 and Figure 9 As shown, the plug-in structure 241 includes a tongue arranged from the connecting end 22 toward the third direction, the tongue is inserted into the plug-in position 11, and is restricted by the plug-in position 11 to move toward the fifth direction; wherein, the third direction is the direction of the pressing end 23 of the pressing portion 2 toward the connecting end 22, and the third direction is Figure 6 The middle horizontal direction is to the left, and the third direction is already Figure 6 and Figure 3 In a specific embodiment, the connecting end 22 of the pressing portion 2 extends an extension wall 2411 toward the second direction, and the bottom end of the extension wall 2411 is provided with the inserting tongue protruding toward the third direction; the number of the inserting tongues is set to two, and the two inserting tongues are arranged at intervals along the first direction, and the first direction is set as the arrangement direction of the button 21. The first direction has been Figure 3 Marked in. The number of the abutment structures 242 is set to two, and the two abutment structures 242 are arranged at intervals along the first direction, and in the first direction, the two abutment structures 242 are located between the two plug-in structures 241. In addition, each button 21 is provided with one of the movable snap-fit ​​structures 243 and one of the trigger columns 211, and each of the movable snap-fit ​​structures 243 and each of the trigger columns 211 are arranged along the first direction. It is worth noting that in the third direction, the movable snap-fit ​​structure 243, the trigger column 211, the abutment structure 242, and the plug-in structure 241 are arranged in sequence. Further, as Figure 9 As shown, the plug-in position 11 includes a transversely arranged limiting rib, which abuts against the upper surface of the plug-in tongue to limit the upward movement of the plug-in tongue.

[0092] Furthermore, if Figure 6 and Figure 3 As shown, the support and limiting structure 12 is constructed as a first rotating shaft 121, and the abutting structure 242 is provided with a trumpet-shaped abutting recess 2421 toward the first rotating shaft 121. The abutting recess 2421 abuts the first rotating shaft 121 to limit the translation of the pressing portion 2 in the direction opposite to the third direction, thereby limiting the insertion structure 241 from being separated from the insertion position 11. The trumpet shape includes all trumpet-like shapes, rather than a specific trumpet shape. Figure 9 As shown, the first rotating shafts 121 are integrally formed on the panel base 1 , the number and positions of the first rotating shafts 121 correspond one-to-one to the abutting recesses 2421 , and the first rotating shafts 121 are coaxially arranged.

[0093] Furthermore, when the button 21 is pressed, the pressing portion 2 rotates slightly based on the first rotating shaft 121. Figure 6 and Figure 7 As shown, the top of the abutting recess 2421 is configured to be arc-shaped, and its curvature is consistent with the curvature of the first rotating shaft 121, so that the abutting recess 2421 can rotate in accordance with the first rotating shaft 121, thereby making the pressing feel smoother.

[0094] Furthermore, if Figure 6-Figure 9As shown, the movable snap-fit ​​structure 243 is constructed as a first snap-fit ​​extending from the button 21 toward the second direction, and the panel base 1 is provided with a first snap-fit ​​position 13 adapted to the first snap-fit, and the movable snap-fit ​​structure 243 is snap-fitted to the first snap-fit ​​position 13; the first snap-fit ​​position 13 reserves a movable space in the second direction, so that the first snap-fit ​​can move toward the second direction.

[0095] According to the embodiment of the present utility model, Figure 3 、 Figure 9 and Figure 10 As shown, a snap-fitting rotating structure 244 is provided on both sides of the pressing portion 2 facing the second direction, and the panel base 1 has a second rotating shaft 14 at a position corresponding to the snap-fitting rotating structure 244. The snap-fitting rotating structure 244 is snapped 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 snap-fitting rotating structure 244 is to improve the connection stability between the two sides of the pressing portion 2 and the panel base 1. When the button 21 is pressed, the snap-fitting rotating structure 244 can also provide supporting force and limiting force, making the pressing movement of the button 21 more stable and reliable. And when disassembling the pressing portion 2, if the movable snap-fitting structure 243 is disengaged from the panel base 1, the snap-fitting rotating structure 244 can provide auxiliary snap-fitting force to prevent the pressing portion 2 from falling. Among them, Figure 10 This is a simplified assembly diagram of the pressing portion 2 and the panel base 1. Figure 10 Some of the structures in have been simplified, but Figure 10 The plug-in structure 241, the locking and rotating structure 244, the movable locking structure 243 and Figure 3 and Figure 9 It should be noted that the plug-in structure 241, the locking rotation structure 244 and the movable locking structure 243 are not on the same vertical plane (by Figure 3 As can be seen), Figure 10 By combining the three elements into one section through stepped sectioning, the structure can be displayed more intuitively.

[0096] Furthermore, if Figure 10 As shown, the snap-in rotating structure 244 includes a rotating hole 2441 and a snap interface 2442 connected to the rotating hole 2441, and the second rotating shaft 14 is snapped into the rotating hole 2441 by the snap interface 2442; the opening direction of the snap interface 2442 is set to be an inclined direction between the second direction and the third direction, wherein the third direction is the direction of the pressing end 23 of the pressing portion 2 toward the connecting end 22, and the second direction and the third direction are already Figure 10 The winning bid is out. Among them, Figure 10The figure includes three figures, which correspond to the three states during the installation of the pressing part 2. The first state is the state in which the pressing part 2 is detached, the second state is the state in which the pressing part 2 is installed, and the third state is the state in which the pressing part 2 is installed. In the second state, the plug-in structure 241 of the pressing part 2 is inserted obliquely into the plug-in position 11 toward the lower left, the card interface 2442 of the card-connecting rotating structure 244 abuts against the second rotating shaft 14, and the movable card-connecting structure 243 has not yet been inserted into the panel base 1; at this time, due to the overall inclination of the pressing part 2, the opening direction of the card interface 2442 just becomes vertically downward. When the pressing part 2 rotates downward based on the plug-in structure 241, the movement direction of the card interface 2442 just coincides with the opening direction of the card interface 2442, so that the card interface 2442 can be smoothly inserted into the second rotating shaft 14; then, the movable card-connecting structure 243 is inserted into the first card position 13, and the installation is completed. In addition, the disassembly process of the pressing portion 2 is the opposite of the installation process. During the disassembly process, the movable engaging structure 243 is first disengaged from the first engaging position 13, and then the pressing portion 2 is rotated upward based on the plug-in structure 241, so that the engaging rotation structure 244 can be disengaged from the second rotating shaft 14. At this time, the abutting structure 242 is also disengaged from the supporting and limiting structure 12, and the plug-in structure 241 can be disengaged from the plug-in position 11, thereby removing the pressing portion 2. In this embodiment of the utility model, since the opening direction of the card interface 2442 is an inclined direction, the installation and disassembly process of the pressing portion 2 is relatively simple and convenient. In addition, the engaging rotation structure 244 cooperates with the abutting structure 242, making it easier to disassemble and install the pressing portion 2 as a whole, avoiding damage to the connecting end 22 by disassembling each button 21 one by one.

[0097] Furthermore, if Figure 4 and Figure 3As shown, the buttons 21 at the 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 portion 2 so that when one of the buttons 21 is pressed, the other buttons 21 will not follow the movement. The first surface 27 is set as the side of the pressing portion 2 facing away from the second direction. The connecting structure 25 protrudes from the second surface 28 of the pressing portion 2 to enhance the strength of the connection between the buttons 21. The second surface 28 is set as the side of the pressing portion 2 facing the second direction. The first surface 27 is the upper surface of the pressing portion 2 in this embodiment, and the second surface 28 is the lower surface of the pressing portion 2 in this embodiment. Furthermore, two adjacent buttons 21 are separated by a dividing seam 26, and a strip groove 251 is provided on the first surface 27 of the pressing portion 2 at a corresponding position of the connecting structure 25. The strip groove 251 extends from 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 the movement.

[0098] According to the embodiment of the present utility model, Figure 13 and Figure 9As shown, the intelligent switch 100 also includes a circuit board 5. The panel base 1 is covered with the bottom shell 3, forming a housing cavity with the bottom shell 3. The circuit board 5 is housed in the housing cavity and carries a high-voltage circuit and a low-voltage circuit. The bottom shell 3 is provided with a mounting hole 31 for inserting a mounting screw 32, and the bottom shell 3 is mounted to the outside via the mounting screw 32. The panel base 1 is provided with an operation hole 15 at a position corresponding to the mounting hole 31. The nut of the mounting screw 32 is exposed in the operation hole 15. The button 21 covers the operation hole 15 so that when the button 21 is removed, the mounting screw 32 can be operated. Among them, the utility model concentrates the high-voltage circuit and the low-voltage circuit on a single circuit board 5, which can save space in the bottom shell 3, making the bottom shell 3 smaller and making it easier to place the bottom shell 3 in a dark box, thereby improving the installation convenience of the intelligent switch 100. At the same time, it also leaves more space in the dark box to accommodate other structures, such as wiring harnesses. However, since the high-voltage circuit and the low-voltage circuit are arranged on the same circuit board 5, the circuit board 5 cannot be exposed to the outside to prevent electric shock. For this reason, the circuit board 5 of the utility model is contained 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. The embodiment of the utility model sets the mounting hole 31 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 hidden box on the wall, thereby fixing the smart switch 100 to the wall; the panel base 1 does not need to be removed during the installation process, which not only protects the circuit board 5 from damage, but also avoids the risk of electric shock caused by the circuit board 5 being exposed to the outside.

[0099] According to the embodiment of the present utility model, Figure 15 、 Figure 17 and Figure 19 As shown, since the circuit board provided in this embodiment carries both strong and weak electricity, the circuit board needs to avoid being exposed to the outside when it is powered on. Based on this, 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 can be operated to disassemble the panel base 1 from the bottom shell 3. The disassembly structure 16 is arranged on the back of the panel base 1 so that when the smart switch 100 is installed on the wall, the disassembly structure 16 is hidden between the panel base 1 and the wall, and the user cannot disassemble the panel base 1, thereby avoiding the user from accidentally disassembling the panel base 1, resulting in the circuit board 5 being exposed and posing a risk of electric shock. Among them, the disassembly structure 16 can be a buckle, a screw or other structure that can be operated to disassemble the panel base 1 from the bottom shell 3.

[0100] In an exemplary embodiment, Figure 15 and Figure 17 As shown, the disassembly structure 16 includes a second clip 161, and the bottom shell 3 is provided with a second clipping position 33 adapted to the second clip 161. The second clip 161 is engaged with the second clipping position 33, and the second clip 161 can be pried to detach the panel base 1 from the bottom shell 3; wherein, the second clip 161 is integrally formed on the inner side of the side wall of the panel base 1, and the second clipping 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 mounted on a wall, the second clip 161 is hidden between the panel base 1 and the wall;

[0101] In another exemplary embodiment, Figure 19 As shown, the disassembly structure 16 includes a connecting screw 162, the left end of the panel base 1 is buckled into 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, and the connecting screw 162 passes through the countersunk hole and is connected to the threaded connection hole to realize the detachable connection between the panel base 1 and the bottom shell 3; wherein, 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 generally fix the high-voltage circuit board to the bottom shell. When the bottom shell is installed on the wall, it is easy to deform toward the inside of the wall, causing the high-voltage circuit board to move toward the inside of the wall. In the present utility model, the high-voltage circuit and the low-voltage circuit are concentrated on the same circuit board 5, and the detection member 52 is also set on the circuit board 5. If the circuit board 5 moves toward the inside of the wall, the gap between the button 21 and the detection member 52 will become larger, and the button 21 may not be able to trigger the detection member 52. In addition, when the bottom shell 3 is greatly deformed, the circuit board 5 is easily damaged. To solve this problem, according to the embodiment of the present utility model, 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. Therefore, when the bottom shell 3 is greatly deformed, it will not directly affect the circuit board 5, thus avoiding damage to the circuit board 5. The opposite sides of the bottom shell 3 are provided with mounting holes 31 for external installation. The two sides of the bottom shell 3 without the mounting holes 31 are connected to the panel base 1, so that when the bottom shell 3 is deformed during installation, the deformation of the panel base 1 and the circuit board 5 following the deformation of the bottom shell 3 is reduced, thereby ensuring that the button 21 can accurately trigger the detection member 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 includes two figures, the first figure is a schematic diagram of the structure of the bottom shell 3 before deformation, and the second figure is a schematic diagram of the structure of the bottom shell 3 after deformation.

[0103] In a specific embodiment, the bottom shell 3 includes a first side and a second side arranged opposite to each other, and a first end and a second end arranged opposite to each other, and the first side, the first end, the second side and the second end are adjacently enclosed in the bottom shell 3 in sequence; 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 holes 31, the first end and the second end of the bottom shell 3 respectively abut against the wall to be supported by the wall; the mounting holes 31 are connected to the dark box through the mounting screws 32. If the mounting screws 32 are over-tightened, the first side and the second side of the bottom shell 3 will be driven by the mounting screws 32 to deform downward. At this time, the first end and the second end of the bottom shell 3 change less due to being supported by the wall. Since the panel base 1 is connected to the first end and the second end, and is not connected to the first side and the second side, the panel base 1 is less 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, thereby ensuring that the first circuit board 5 will not deform downward with the bottom shell 3, so that the relative position relationship between the button 21 set on the panel base 1 and the circuit board 5 will not be affected by the deformation of the bottom shell 3, ensuring that the button 21 can accurately trigger the detection member 52 even when the bottom shell 3 is deformed.

[0104] Furthermore, the bottom shell 3 does not provide direct fixing constraints for 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, if Figure 15 As shown, the panel base 1 and the bottom shell 3 are detachably connected, so that when the panel base 1 is removed from the bottom shell 3, each of the circuit boards 5 is removed from the bottom shell 3 along with the panel base 1. Then, during the assembly process, only the circuit boards 5 need to be fixed to the panel base 1, and the bottom shell 3 can be quickly and conveniently fastened to the panel base 1 to complete the assembly, thereby improving assembly efficiency. The connection method between the panel base 1 and the bottom shell 3 can be a snap 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 snap-fit ​​position 161 that cooperates with the second snap-fit ​​position 33, and the second snap-fit ​​position 161 is fastened to the second snap-fit ​​position 33.

[0106] According to the embodiment of the present utility model, Figure 15-16 and Figure 11As shown, the number of the circuit board 5 is one, and the circuit board 5 is connected to the external wire and is equipped with a high-voltage circuit and a low-voltage circuit. The circuit board 5 is provided with a relay 40, a power supply circuit 50 and the detection component 52; the power supply circuit 50 is electrically connected to the external wire and is used to convert AC power into DC power; the detection component 52 is used for detection and manipulation, and the relay 40 is electrically connected to the detection component 52 and can switch the on-off state in response to the detection component 52 being manipulated. In a specific embodiment, a plurality of wiring terminals 53 are provided on the lower surface of the circuit board 5, and the wiring terminals 53 are connected to the neutral wire, the live wire and the wire for controlling the on and off of the controlled device 200. The power supply circuit 50 and the relay 40 are provided on the lower surface of the circuit board 5, and the power supply circuit 50 is electrically connected to the wiring terminals 53, and can convert 220V AC power into low-voltage DC power, thereby supplying power to the low-voltage circuit. The power supply circuit 50 is composed of electronic components such as transformers, capacitors, inductors, and resistors. Figure 16 is a bottom view of the circuit board 5, Figure 16 The electronic components in the dotted box in the figure constitute the power supply circuit 50. The number of the relays 40 is equal to the number of the buttons 21. The relays 40 are electrically connected to the terminal 53 and are used to control the on and off of the controlled device 200.

[0107] Furthermore, if Figure 15 and Figure 17 As shown, the wiring terminals 53 are welded to the lower surface of the circuit board 5, and the bottom shell 3 is provided with wiring slots 34 at positions corresponding to the wiring terminals 53. Each wiring terminal 53 is accommodated in each wiring slot 34. The bottom of the wiring slot 34 is provided with a wiring hole, and the wire passes through the wiring hole to connect to the wiring terminal 53. The side of the wiring slot 34 is provided with a locking hole, and the wiring screw of the wiring terminal 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 is to be accommodated in each wiring slot 34 and the position of the locking hole is to correspond to the wiring screw, the relative position accuracy of the terminal 53 and the wiring slot 34 is required to be high. Figure 16 and Figure 15 As shown, in this embodiment, elongated first positioning holes 54 are provided between each of the wiring terminals 53. The bottom case 3 is provided with elongated positioning ribs 341 between each of the wiring slots 34. These positioning ribs 341 are inserted into the first positioning holes 54 to ensure positioning between the bottom case 3 and the circuit board 5. The positioning ribs 341 extend upward from the bottom, so that when the bottom case 3 deforms downward, the positioning ribs 341 do not affect the circuit board 5.

[0109] Furthermore, if Figure 9 and Figure 11As shown, the detection member 52 is disposed on a side of the circuit board 5 facing the button 21. The panel base 1 is provided with a trigger hole 17 at a position corresponding to the detection member 52. The button 21 is provided with a trigger post 211 facing the detection member 52. The trigger post 211 passes through the trigger hole 17 and abuts against the detection member 52. The number of the detection member 52, the trigger post 211, and the trigger hole 17 corresponds to the number of the buttons 21.

[0110] According to the embodiment of the present utility model, Figure 15 and Figure 18 As shown, the circuit board 5 is fixedly connected to the panel base 1 via a plurality of fixing screws 554. The bottom case 3 is provided with a relief recess 35 at the position corresponding to 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 case 3, thereby reducing the thickness of the panel base. The close proximity can be understood as a spacing of less than 2 mm between the circuit board 5 and the bottom case 3. In one embodiment, the circuit board 5 is in contact with the upper surface of the bottom case 3.

[0111] Furthermore, if Figure 11 As shown, the panel base 1 is provided with two second positioning columns 181, multiple second threaded connection holes 182 and three square protrusions 183 facing the circuit board 5, and the circuit board 5 is provided with second positioning holes 551, second connection through holes 552 and square holes 553 in a one-to-one correspondence. The second positioning column 181 is inserted into the second positioning hole 551 to position the circuit board 5 and the panel base 1; the fixing screw 554 passes through the second connection through hole 552 and is connected 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, and the first clamping position 13 is provided in the square protrusion 183, and the square protrusion 183 is hollow, and provides the movable clamping structure 243 with movable space.

[0112] According to the embodiment of the present utility model, 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, and no copper foil is laid on the circuit board 5 at the corresponding position of the wireless communication module 56, so that the wireless signal can pass through the circuit board 5, thereby preventing the circuit board 5 from shielding the wireless signal.

[0113] Since the circuit board 5 of the present invention carries a strong current circuit, there is a certain probability that the strong current on the circuit board 5 will be transmitted along the surface of the insulating material to the mounting screws 32. Therefore, it is necessary to design a sufficient creepage distance to prevent the current on the circuit board 5 from leaking to the mounting screws 32. The so-called creepage distance is the shortest spatial distance between two conductive components measured along the surface of the insulating material. According to the embodiment of the present invention, if Figure 15 and Figure 13 As shown, the bottom shell 3 is provided with an isolation wall 36 protruding around the mounting hole 31 toward the panel base 1, and the circuit board 5 is provided 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, avoiding the user from touching the mounting screw 32 and getting an electric shock.

[0114] In existing switches with display screens, the display screen is generally placed between a panel base and a transparent cover. The panel base limits the sides of the display screen, and the transparent cover covers the upper surface of the display screen to fix the display screen. The transparent cover is adhered to both the panel base and the display screen. When the display screen needs to be removed, the transparent cover needs to be removed first, which makes removal difficult. Moreover, when there are multiple display screens, this display screen fixing method makes it difficult to remove one of the display screens without affecting the other display screens. Therefore, it is not suitable for the smart switch with multiple display screens provided by the present invention. Therefore, according to an embodiment of the present invention, if Figure 14 、 Figure 11 and Figure 12As shown, the panel base 1 is provided with a circuit board 5 on the side away from the pressing portion 2, the display screen 101 is provided between the panel base 1 and the circuit board 5, and the display screen 101 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 surface of the display screen 101 and the third surface 1011 respectively abut against the panel base 1, so that the display screen 101 is limited by the panel base 1; the third surface 1011 is provided with a display area 1012, the panel base 1 is provided with a display through hole 191 at a position opposite to the display area 1012, and the side of the panel base 1 away from the circuit board 5 is covered with a transparent cover plate 4, the transparent cover plate 4 covers the display through hole 191, and 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 the embodiment of the present invention is installed into the panel base 1 from the side of the panel base 1 facing 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, it is only necessary to remove the circuit board 5 to remove each display screen 101 separately. The display screen 101 will not affect the assembly status of other display screens 101 during the disassembly process, which is more suitable for the structure of multiple display screens 101 of the embodiment of the present invention. In addition, there is no need to remove the transparent cover plate 4 during the disassembly process, which reduces the difficulty of disassembly and assembly.

[0115] The display screen 101 abutting against the panel base 1 can be understood as the display screen 101 directly abutting against the panel base 1 or indirectly abutting against the panel base 1 through other structures. Figure 14 As shown, a first double-sided tape (not shown in the figure) is provided between the display screen 101 and the panel substrate 1, and the display screen 101 is adhered to the panel substrate 1 by the first double-sided tape. The first double-sided tape covers the periphery of the third surface 1011 so that the third surface 1011 is sealed and connected to the lower side of the display through hole 191. In addition, as shown Figure 20 As shown, the transparent cover plate 4 is adhered to the upper side of the display through hole 191 by the 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 water vapor from entering between the transparent cover plate 4 and the display screen 101 and affecting the display effect.

[0116] Furthermore, if Figure 12 As shown, the panel base 1 is provided with abutting ribs 192 around the sides of the display screen 101 . The abutting ribs 192 abut against the sides of the display screen 101 to limit the sides of the display screen 101 .

[0117] Furthermore, if Figure 11As shown, the circuit board 5 is fixedly connected to the panel base 1 via a plurality of fixing screws 554, facilitating the removal of the circuit board 5 and, in turn, the display screen 101. The display screen 101 and the circuit board 5 are connected via a flexible cable 1013, which facilitates disconnection when the circuit board 5 is removed. This improves the efficiency of replacing the display screen 101.

[0118] According to the embodiment of the present utility model, Figure 14 As shown, the circuit board 5 is provided with a cable connection terminal 57, and the display screen 101 is provided with a cable 1013 facing the third direction. The cable 1013 is bent and inserted into the cable connection terminal 57. The third direction is the direction from the pressing end 23 of the pressing portion 2 to the connecting end 22. The third direction is already in the Figure 14 In this embodiment of the utility model, the flexible cable 1013 of the display screen 101 is arranged in a direction 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. It also avoids the flexible cable 1013 and the pressing portion 2 from overlapping in the thickness direction. While reducing the thickness of the smart switch 100, it can also prevent the movement of the pressing portion 2 from driving the flexible cable 1013 and causing damage to the flexible cable 1013.

[0119] Further, if Figure 14 and Figure 11 As shown, a support foam 59 is disposed between the display screen 101 and the circuit board 5 to provide support for the display screen 101. The upper end of the support foam 59 abuts and adheres to the display screen 101, while the lower end abuts the circuit board 5. The support foam 59 is in a compressed state, thereby providing support for the display screen 101 and ensuring a more stable connection between the display screen 101 and the panel substrate 1. The cable connection terminal 57 is disposed below and covered by the support foam 59, ensuring a more stable connection between the cable 1013 and the cable connection terminal 57.

[0120] According to the embodiment of the present utility model, Figure 20 and Figure 5 As shown, a light-shielding layer 42 is provided on one side of the transparent cover plate 4 facing the panel substrate 1; a display window 421 is provided on the light-shielding layer 42 at a position directly opposite to 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 silk-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 a high-voltage circuit and a low-voltage circuit, the display screen 101 is regarded as a charged body, and the creepage distance between the display screen 101 and the outer surface of the switch needs to be greater than 2 mm to avoid electric shock to the user. For this purpose, 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 presence of the preset gap, when the smart switch 100 is mounted on the wall, the upper end 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 the human eye, the viewing angle of the display screen 101 is tilted downward, resulting in the upper edge of the display window 421 blocking a portion of the display area 1012). For this reason, a blank area ( Figure 21 Not shown), no content is displayed in the blank area to avoid the displayed 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 set as the upper horizontal area of ​​the display area 1012. Figure 21 As shown, the display window 421 is arranged opposite to the display area 1012 , and the size of the display window 421 is slightly larger than the size of the display area 1012 to reduce the amount of occlusion of the display area 1012 by the display window 421 .

[0122] According to the embodiment of the present utility model, Figure 6 As shown, the transparent cover plate 4 is arranged in parallel with the connecting end 22 of the pressing portion 2, and the side of the transparent cover plate 4 facing the fifth direction is flush with the side of the pressing portion 2 facing the fifth direction. In one embodiment, when the pressing portion 2 is not pressed, the transparent cover plate 4 and the pressing portion 2 are both Figure 6 The horizontal state.

[0123] According to the embodiment of the present utility model, Figure 11 and Figure 20As shown, the circuit board 5 is provided with an infrared detection device 20. The infrared detection device 20 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 functions to detect the distance between an external object and the intelligent switch 100, and triggers the display screen 101 when the distance is sufficiently close. 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 distance between the external object and 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 exceeds a threshold, the intelligent switch 100 determines that the distance between the external object and the intelligent switch 100 is less than a predetermined distance, and controls the display screen 101 to illuminate. The detection wave can be an infrared light wave or other electromagnetic wave. 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 have discovered that the detection wave emitted by the infrared emitting unit 201 can easily be transmitted from the inside of the intelligent switch 100 to the infrared receiving unit through two erroneous pathways, causing the infrared detection device 20 to misjudge. One is that the detection wave is transmitted to the infrared receiving unit 202 through total 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 and is transmitted to the infrared receiving unit 202. Or, when the panel substrate 1 is thin and light in color, the detection wave directly penetrates the panel substrate 1 and is transmitted to the infrared receiving unit 202. In order to reduce these two erroneous transmission pathways, the present invention adopts the following scheme: Figure 20 、 Figure 11 and Figure 6 As shown, the infrared emitting unit 201 includes an infrared light-emitting tube 2012, and the infrared receiving unit 202 includes an infrared receiving head 2021. At least one display screen 101 is disposed between the infrared light-emitting tube 2012 and the infrared receiving head 2021, thereby increasing the distance between the infrared receiving head 2021 and the infrared light-emitting tube 2012, thereby reducing the total reflection of the detection wave within the transparent cover 4. The infrared light-emitting tube 2012 is surrounded by a shielding member 58, which blocks the detection wave from the side of the infrared light-emitting tube 2012, thereby reducing the detection wave from passing through the gap between the panel base 1 and the circuit board 5 or penetrating the panel base 1 to the infrared receiving unit 202. These two solutions reduce the transmission of the detection wave within the intelligent switch 100, avoiding misjudgment by the infrared detection device 20.

[0125] It is worth mentioning that increasing the distance between the infrared receiving head 2021 and the infrared light-emitting tube 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 surface of the switch, due to their small size, their bodies can only cover one of the infrared light-emitting tube 2012 or the infrared receiving head 2021, which is not enough to trigger the infrared detection device 20.

[0126] In one embodiment, if Figure 20 As shown, there are three display screens 101 , which are spaced apart 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 receiving head 2021 is disposed between the middle display screen 101 and the right display screen 101 .

[0127] Further, if Figure 6 、 Figure 11 and Figure 20 As shown, the shielding member 58 is a black annular foam that surrounds the infrared light-emitting tube 2012. The upper end of the annular foam abuts against the adhesive backing 41 of the transparent cover plate 4, and the lower end abuts against the circuit board 5, thereby preventing the detection wave from passing through the annular foam from the side. It is worth noting that because the annular foam is a flexible material, it can fit tightly against the circuit board 5, preventing the detection wave from propagating out of the gap between the annular foam and the circuit board 5. Furthermore, the panel base 1 is provided with a transmitting through hole 193 and a receiving through hole 194 at positions corresponding to the annular foam and the infrared receiving head 2021. The transmitting through hole 193 accommodates the annular foam and limits the annular foam, and the receiving through hole 194 accommodates the infrared receiving head 2021.

[0128] Further, if Figure 20 and Figure 5As shown, the light shielding layer 42 has a transmitting window 422 directly opposite the infrared light emitting tube 2012, and a receiving window 423 directly opposite the infrared receiving head 2021. The infrared receiving head 2021 receives external detection waves through the receiving window 423. The infrared light emitting tube 2012 transmits the detection wave through the transmitting window 422, and the transmission angle of the detection wave is limited to less than 90° by the transmitting window 422. When the distance between the infrared light emitting tube 2012 and the light shielding layer 42 is fixed, the smaller the size of the transmitting window 422, the smaller the detection wave transmission angle, and the smaller the detection angle of the infrared detection device 20. When the size of the transmitting window 422 is constant, the larger the distance between the infrared light emitting tube 2012 and the transparent cover plate 4, the smaller the detection wave transmission angle, and the smaller the detection angle of the infrared detection device 20. By controlling the size of the transmitting window 422 and the distance between the infrared light emitting tube 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 utility model, the detection angle of the infrared detection device 20 is controlled to be less than 90°. The reason is that when the detection angle is too large, the infrared detection device 20 is easily triggered by mistake. When the detection angle is too small, the smart switch 100 is likely to fail to trigger when the user approaches from the side. Therefore, the inventors have experimentally verified that the detection angle is controlled within 30°-60° to achieve an appropriate triggering range.

[0129] Further, if Figure 20 As shown, the adhesive backing 41 of the transparent cover plate 4 is respectively provided with a first adhesive hole 411, a second adhesive hole 412 and a third adhesive hole 413 at positions opposite to the display window 421, the transmitting window 422 and the receiving window 423. The sizes of the first adhesive hole 411, the second adhesive hole 412 and the third adhesive hole 413 are respectively larger than the sizes of the display window 421, the transmitting window 422 and the receiving window 423.

[0130] In another embodiment, if Figure 22 As shown, this embodiment is Figures 1-21 The difference between the embodiments is that the insertion structure 241 and the insertion position 11 are relatively loosely matched. When the button 21 is pressed, the pressing portion 2 pivots about the first rotating shaft 121, and the insertion structure 241 no longer provides a reset force. A reset foam 29 is provided between each button 21 and the panel base 1, and the reset force is provided by the reset foam 29. Compared to springs, foam has the characteristic of slow rebound. Using foam to provide the reset force can make the pressing feel of the button 21 damped, and the pressing feel is more advanced. Furthermore, a foam mounting position 291 is provided on the lower surface of the button 21, and the reset foam 29 is adhered to the foam mounting position 291. Furthermore, in the first direction, reinforcing ribs are provided on both sides of each button 21 to increase the rigidity of the button 21.

[0131] Further, if Figure 22 As shown, each key 21 is provided with a thinning bevel 261 on one side adjacent to the other keys 21. The thinning bevel 261 is used to reduce the thickness of the edge of the key 21, making the thickness of the key 21 thinner near the connecting structure 25, thereby reducing the linkage effect between the keys 21, that is, the movement of one key 21 will not drive the movement of other adjacent keys 21. In addition, the provision of the thinning bevel 261 on the key 21 can also increase the width of the injection mold at that location, thereby making the injection mold corresponding to that location less susceptible to damage. Specifically, if the key 21 is not provided with the thinning bevel 261, the injection mold at the location corresponding to the dividing seam 26 will be slender and easily damaged. The thinning bevel 261 reduces the thickness of the key 21 at the location corresponding to the dividing seam 26, and accordingly, the injection mold at that location becomes wider, thereby increasing the strength of the injection mold.

[0132] In another embodiment, if Figure 23 As shown, the transparent cover 4 is not shown in the figure. This embodiment is a two-button version of the smart switch 100. Figures 1-21 The difference between the embodiments is that the number of the buttons 21 is two, and correspondingly, the number of the display screen 101, the relay 40, the detection member 52, the trigger hole 17, and the trigger column 211 are each two. The infrared light-emitting tube 2012 is arranged between the two display screens 101, and the infrared receiving head 2021 is arranged on the right side of the right display screen 101, so that the distance between the infrared light-emitting tube 2012 and the infrared receiving head 2021 is increased, thereby reducing the total reflection of the detection wave inside the transparent cover 4 and avoiding misjudgment of the infrared detection device 20. The display screen 101, the infrared light-emitting tube 2012, and the infrared receiving head 2021 are arranged side by side along the first direction. The panel base 1 is provided with the display through hole 191, the transmitting through hole 193, and the receiving through hole 194 at the corresponding positions of the display area 1012 of the display screen 101, the infrared light-emitting tube 2012, and the infrared receiving head 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 a movable engaging structure 243. The number and position of the first engaging positions 13 of the panel base 1 are the same as those of the three-button version of the smart switch 100, both being three. The first engaging positions 13 on the left and right sides of the panel base 1 are respectively engaged with the movable engaging structures 243 of the two buttons 21.

[0133] In another embodiment, if Figure 24 As shown in the figure, the transparent cover 4 is not shown. This embodiment is a single-button version of the smart switch 100. Figures 1-21The difference between the embodiments is that the number of the button 21 is one, and correspondingly, the number of the display screen 101, the relay 40, the detection element 52, the trigger hole 17, and the trigger column 211 are each one. The infrared light-emitting tube 2012 is arranged on the left side of the display screen 101, and the infrared receiving head 2021 is arranged on the right side of the display screen 101, so that the distance between the infrared light-emitting tube 2012 and the infrared receiving head 2021 is increased, thereby reducing the total reflection of the detection wave inside the transparent cover 4 and avoiding misjudgment of the infrared detection device 20. The display screen 101, the infrared light-emitting tube 2012, and the infrared receiving head 2021 are arranged side by side along the first direction. The panel base 1 is provided with the display through hole 191, the transmitting through hole 193, and the receiving through hole 194 at the corresponding positions of the display area 1012 of the display screen 101, the infrared light-emitting tube 2012, and the infrared receiving head 2021, respectively. 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 movable engaging structures 243. The number and position of the first engaging positions 13 of the panel base 1 are the same as those of the three-button version of the smart switch 100, both being three. The first engaging positions 13 on the left and right sides of the panel base 1 are respectively engaged with the two movable engaging structures 243 of the button 21.
