[0056] At present, the key version intelligent switch is mostly preprinted with characters or patterns on the key to prompt the key function, if the user changes the function corresponding to the key, the key needs to be replaced synchronously, which brings inconvenience to the user and causes waste. In order to solve this problem, please refer to Figures 1-24 The utility model provides a kind of intelligent switch 100 is specifically illustrated. As Figures 1-5As shown, the intelligent switch 100 comprises a panel base body 1, a pressing part 2 and a display device 10; the pressing part 2 is connected to the panel base body 1, the pressing part 2 comprises a plurality of keys 21; the display device 10 comprises a plurality of display screens 101 corresponding to each key 21, each display screen 101 is arranged on the panel base body 1 and is used for displaying key information of the corresponding key 21; the intelligent switch 100 can display corresponding information of each key 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 key function, thereby solving the problem that the pattern or the text needs to be changed by replacing the key 21 in the prior art. Wherein, the display screen 101 corresponding to the key 21 can be understood as that the number of the display screen 101 is equal to the number of the key 21, and the position of the display screen 101 corresponds to the position of the key 21, for example, each display screen 101 can be arranged near the end of each key 21. The advantage of using a plurality of independent display screens 101 compared with using an integral 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 individually, thereby saving maintenance cost.

[0057] In addition, as shown, Figures 1-5 As shown, the intelligent switch 100 comprises a panel base body 1, a pressing part 2 and a display device 10; the pressing part 2 is connected to the panel base body 1, the pressing part 2 comprises a plurality of keys 21; the display device 10 comprises a plurality of display screens 101 corresponding to each key 21, each display screen 101 is arranged on the panel base body 1 and is used for displaying key information of the corresponding key 21; the intelligent switch 100 can display corresponding information of each key 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 key function, thereby solving the problem that the pattern or the text needs to be changed by replacing the key 21 in the prior art. Wherein, the display screen 101 corresponding to the key 21 can be understood as that the number of the display screen 101 is equal to the number of the key 21, and the position of the display screen 101 corresponds to the position of the key 21, for example, each display screen 101 can be arranged near the end of each key 21. The advantage of using a plurality of independent display screens 101 compared with using an integral 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 individually, thereby saving maintenance cost.

[0058] The end portions of each key 21 of the intelligent switch 100 are connected to each other, so that the spacing between the keys 21 is kept consistent, and the positional correspondence relationship between the keys 21 and the display screen 101 is more accurate; meanwhile, since the end portions of the keys 21 are connected, the keys 21 can provide reset force to each other, without the need for an additional reset structure, so that the structure is simplified; and since the keys 21 are connected, the keys 21 will not shake or become loose, and the pressing feeling is improved.

[0059] According to the embodiment of the utility model, Figure 9 and Figure 13 As shown, the intelligent switch 100 further comprises a bottom shell 3, which is provided with a mounting hole 31, the mounting hole 31 is used for external installation, and the pressing portion 2 covers the mounting hole 31; when installing the intelligent switch 100, the user only needs to disassemble the pressing portion 2, so that the mounting hole 31 is exposed, and then the mounting screw 32 is connected to the hidden box of the wall through the mounting hole 31, so that the intelligent switch 100 is fixed to the wall; the mounting process does not need to disassemble the panel base body 1, so that the internal circuit board 5 is protected, and the risk of falling and breaking after the circuit board 5 is disassembled with the panel base body 1 is avoided.

[0060] Since the intelligent switch 100 provided by the utility model needs to disassemble the keys 21 before external installation, the keys 21 need to have the characteristics of easy disassembly and assembly, and each key 21 cannot be disassembled one by one during disassembly and assembly, so as to avoid the connection end 22 connecting the keys 21 being broken. Based on this, the utility model embodiment provides a kind of continuous row key 21 of easy disassembly and assembly, including plug-in structure 241, abutment structure 242 and movable clamping structure 243, and the three structures cooperate with each other to realize the easy disassembly and assembly effect of key 21. As shown in Figure 6 、 Figure 3 and Figure 9 The connection end 22 of the pressing portion 2 is provided with the plug-in structure 241, the panel base body 1 is provided with plug-in site 11, the plug-in structure 241 is inserted in the plug-in site 11, to be limited by the plug-in site 11 towards fifth direction movement, the fifth direction is opposite to the direction of being pressed of the key 21, wherein, Figure 5 is the top view of the intelligent switch 100, Figure 6 is Figure 5 A-A stepped section view in it, it needs to be noted that the plug-in structure 241, abutment structure 242 and movable clamping structure 243 are not in the same vertical plane (as can be seen from Figure 3 , Figure 6 Three are concentrated in the same section by the way of stepped section, so that structure can be more intuitively displayed. The fifth direction is Figure 6 vertical upward direction in it, and fifth direction has been in 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.

[0061] 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.

[0062] like Figure 8 As shown, Figure 8 for Figure 6The dismounting process schematic view of the pressing part 2 in the faceplate base 1, when the pressing part 2 is dismounted from the faceplate base 1, the user can first bend the pressing end 23 upwards, so that each movable clamping structure 243 is disengaged from the faceplate base 1, and the pressing part 2 can be integrally rotated counterclockwise based on the plug-in structure 241, when the rotation angle reaches a certain value, the abutting structure 242 is disengaged from the support limiting structure 12, and then the pressing part 2 loses the limitation of the support limiting structure 12, so that the plug-in structure 241 can be disengaged from the plug-in position 11 to the right. The whole dismounting process is simple and fast, and is suitable for the characteristics that the smart switch 100 needs to dismount the pressing part 2 and then install it externally. Moreover, compared with the prior art that each key 21 is provided with a hole position and is rotationally connected with the faceplate base 1, the embodiment adopts the scheme that the plug-in structure 241 cooperates with the abutting structure 242, so that the pressing part 2 can be integrally dismounted from the faceplate base 1, without dismounting each key 21 one by one, avoiding the connection end 22 connected with each key 21 from being broken, and therefore, the dismounting scheme of the pressing part 2 is more suitable for the structure of the continuous keys 21 of the utility model.

[0063] Correspondingly, the mounting process of the pressing part 2 is opposite to the dismounting process, as shown in Figure 8 When the pressing part 2 is mounted on the faceplate base 1, the plug-in structure 241 can be obliquely inserted into the plug-in position 11 to the lower left, then the pressing part 2 is integrally rotated clockwise based on the plug-in structure 241, so that the abutting structure 242 abuts against the support limiting structure 12, finally the pressing end 23 is pressed downwards, so that the movable clamping structure 243 is clamped on the faceplate base 1, and the mounting is completed. The whole mounting process is fast and convenient, and is suitable for the characteristics that the smart switch 100 of the utility model needs to mount the pressing part 2 on the faceplate base 1 after being installed on the wall.

[0064] Further, as shown in Figure 8 During the mounting and dismounting process of the pressing part 2, when the pressing part 2 is inclined, the left end of the pressing part 2 abuts against the transparent cover plate 4, in order to ensure that the pressing part 2 can be smoothly mounted and dismounted, as shown in Figure 6 A certain gap is arranged between the left end of the pressing part 2 and the transparent cover plate 4, which reserves a space for the rotation of the pressing part 2, so that during the mounting and dismounting process of the pressing part 2, when the pressing part 2 is inclined, the transparent cover plate 4 will not interfere with the pressing part 2.

[0065] According to the embodiment of the utility model, as shown in Figure 7 and Figure 6As shown, the plug-in position 11 abuts against one 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 limiting structure 12 as the fulcrum. The plug-in position 11 gives the plug-in structure 241 an abutting force towards the second direction, so that the pressing end 23 generates a restoring force. The pressing part 2 is equivalent to a seesaw structure with the support limiting structure 12 as the fulcrum. The plug-in position 11 limits the left end of the pressing part 2 from moving upwards through the plug-in structure 241. When the pressing end 23 at the right end of the pressing part 2 is pressed, the pressing end 23 moves downwards. Since the left end of the pressing part 2 is limited from moving upwards, the pressed key 21 is bent and deformed. The other keys 21 that are not pressed remain in the initial state. The key 21 deforms to generate a restoring force, which is the first restoring force. Furthermore, since the keys 21 are connected to each other through the connecting end 22, the keys 21 can also provide a restoring force to each other, which is the second restoring force. In addition, the key 21 presses the detection member 52, so that the detection member 52 generates a reaction force to the key 21, which is the third restoring force. When the pressing force is removed, the pressed key 21 is restored under the joint action of the first, second, and third restoring forces. Therefore, the key 21 does not need an additional restoring structure, and the structure is simplified.

[0066] Further, the detection member 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 member 52 is a tactile switch.

[0067] Further, as shown in Figure 6 , one side of the circuit board 5 facing the panel base body 1 is provided with the detection member 52. The key 21 is provided with a trigger column 211 facing the detection member 52. When the key 21 is not pressed, the detection member 52 is still pressed by the trigger column 211 to generate a small amount of compression. The compression is not enough to trigger the detection member 52, but can provide a pre-tightening force to the key 21, so that the key 21 is not loose and the pressing feeling is more compact. Moreover, the compression can keep the trigger column 211 and the detection member 52 in abutment at all times, eliminate the gap between the trigger column 211 and the detection member 52, and further eliminate the dead stroke of the key 21, thereby improving the trigger sensitivity of the key 21. Figure 3 、 Figure 6 and Figure 9 , the plug-in structure 241 includes a plug-in tongue provided by the connecting end 22 facing the third direction. The plug-in tongue is inserted into the plug-in position 11 and is limited by the plug-in position 11 from moving towards the fifth direction. The third direction is the direction of the pressing end 23 of the pressing part 2 towards the connecting end 22. The third direction isFigure 6 the third direction has been marked in Figure 6 and Figure 3 In a specific embodiment, the connecting end 22 of the pressing part 2 extends an extension wall 2411 towards the second direction, the bottom end of the extension wall 2411 is provided with the plug tongue towards the third direction; the number of the plug tongue is set to two, the two plug tongues are arranged in the first direction, the first direction is set as the arrangement direction of the key 21, the first direction has been marked in Figure 3 The number of the abutting structure 242 is set to two, the two abutting structures 242 are arranged in the first direction, and in the first direction, the two abutting structures 242 are located between the two plug structures 241. In addition, each key 21 is provided with one movable clamping structure 243 and one trigger column 211, each movable clamping structure 243 and each trigger column 211 are arranged in the first direction. It is worth noting that in the third direction, the movable clamping structure 243, the trigger column 211, the abutting structure 242, and the plug structure 241 are sequentially arranged. Further, as shown in Figure 9 The plug-in position 11 includes a limiting rib arranged transversely, which abuts the upper surface of the plug tongue to limit the upward movement of the plug tongue.

[0068] Further, as shown in Figure 6 and Figure 3 The supporting limiting structure 12 is configured as a first rotating shaft 121, the abutting structure 242 is provided with a trumpet-shaped abutting recess 2421 towards the first rotating shaft 121, the abutting recess 2421 abuts the first rotating shaft 121 to limit the translation of the pressing part 2 towards the direction opposite to the third direction, thereby limiting the plug structure 241 from disengaging from the plug-in position 11. Wherein, the trumpet shape includes all shapes similar to a trumpet, rather than a specific trumpet shape. As shown in Figure 9 The first rotating shaft 121 is integrally formed on the panel base 1, the number and position of the first rotating shaft 121 correspond to the abutting recess 2421 one by one, and each first rotating shaft 121 is coaxially arranged.

[0069] Further, when the key 21 is pressed, the pressing part 2 will slightly rotate based on the first rotating shaft 121, therefore, as shown in Figure 6 and Figure 7 The top of the abutting recess 2421 is provided with a circular arc shape, the radius of the circular arc shape is consistent with the radius of the first rotating shaft 121, so that the abutting recess 2421 can fit the rotation of the first rotating shaft 121, thereby making the pressing feeling more smooth.

[0070] Further, as shown in Figures 6-9As shown, the movable clamping structure 243 is configured as a first clamping buckle extended by the key 21 towards the second direction, the panel base body 1 is provided with a first clamping position 13 matched with the first clamping buckle, and the movable clamping structure 243 is clamped in the first clamping position 13; the first clamping position 13 is provided with a movable space in the second direction, so that the first clamping buckle can move towards the second direction.

The clamping rotating structure 244 can improve the connection stability of the two sides of the pressing part 2 and the panel base body 1, and when the key 21 is pressed, the clamping rotating structure 244 can also provide supporting force and limiting force, so that the pressing movement of the key 21 is more stable and reliable. When the pressing part 2 is disassembled, if the movable clamping structure 243 is disengaged from the panel base body 1, the clamping rotating structure 244 can provide auxiliary clamping force to prevent the pressing part 2 from falling. Among them, Figure 10 is an assembly schematic diagram after the structure of the pressing part 2 and the panel base body 1 is simplified. Although part of the structure in Figure 10 has been simplified, Figure 10 the plug-in structure 241, the clamping rotating structure 244 and the movable clamping structure 243 are consistent with Figure 3 and Figure 9 . It should be noted that the plug-in structure 241, the clamping rotating structure 244 and the movable clamping structure 243 are not in the same vertical plane (as can be seen from Figure 3 , Figure 10 the three are concentrated in the same section by means of stepped section, so that the structure can be more intuitively displayed.

[0072] Further, as shown in Figure 10 , the clamping rotating structure 244 comprises a rotating hole 2441 and a clamping hole 2442 communicated with the rotating hole 2441, and the second rotating shaft 14 is clamped into the rotating hole 2441 through the clamping hole 2442; the opening direction of the clamping hole 2442 is arranged as 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 part 2 towards the connecting end 22, and the second direction and the third direction have been marked in Figure 10 . Among them, Figure 10The three states in the installation process of the pressing part 2 are shown in the three figures. The first state is the state that the pressing part 2 is detached, the second state is the state in the installation process of the pressing part 2, and the third state is the state that the installation of the pressing part 2 is completed. In the second state, the plug-in structure 241 of the pressing part 2 is obliquely inserted into the plug-in position 11 towards the lower left, the clamping interface 2442 of the clamping rotating structure 244 abuts against the second rotating shaft 14, and the movable clamping structure 243 has not been clamped into the panel base body 1. At this time, due to the inclination of the whole pressing part 2, the opening direction of the clamping interface 2442 is just vertical downward, and when the pressing part 2 rotates downward based on the plug-in structure 241, the movement direction of the clamping interface 2442 is just consistent with the opening direction of the clamping interface 2442, so that the clamping interface 2442 can be smoothly clamped into the second rotating shaft 14. Then, the movable clamping structure 243 is clamped into the first clamping position 13, and the installation is completed. In addition, the disassembly process of the pressing part 2 is opposite to the installation process. In the disassembly process, the movable clamping structure 243 is first detached from the first clamping position 13, then the pressing part 2 is rotated upward based on the plug-in structure 241, the clamping rotating structure 244 is detached from the second rotating shaft 14, at this time, the abutting structure 242 is also detached from the supporting limiting structure 12, the plug-in structure 241 can be detached from the plug-in position 11, so that the pressing part 2 is disassembled. In the embodiment of the utility model, due to the inclination of the opening direction of the clamping interface 2442, the installation and disassembly process of the pressing part 2 are relatively simple and convenient, and the clamping rotating structure 244 cooperates with the abutting structure 242, so that the pressing part 2 can be more conveniently disassembled and installed as a whole, and the damage of the connecting end 22 caused by the disassembly of each key 21 is avoided.

[0073] Further, as Figure 4 and Figure 3As shown, the connection structure 25 is recessed in the first surface 27 of the pressing part 2, so that when one of the keys 21 is pressed, the other keys 21 will not be moved; wherein the first surface 27 is arranged as the side of the pressing part 2 facing away from the second direction; the connection structure 25 is protruded from the second surface 28 of the pressing part 2, so as to enhance the strength of the connection between the keys 21; the second surface 28 is arranged as the side of the pressing part 2 facing the second direction. Wherein 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. Further, two adjacent keys 21 are separated by a separation joint 26, and the first surface 27 of the pressing part 2 is provided with a strip-shaped groove 251 at the position corresponding to the connection structure 25, the strip-shaped groove 251 extends in the separation joint 26, so as to reduce the linkage effect between the two adjacent keys 21, so that when one of the keys 21 is pressed, the other keys 21 will not be moved.

[0074] According to the embodiments of the utility model, Figure 13 and Figure 9As shown, the intelligent switch 100 further comprises a circuit board 5, the panel base body 1 is covered on the bottom shell 3, and the bottom shell 3 forms a containing cavity, the circuit board 5 is contained in the containing cavity, and the circuit board 5 is loaded with strong current circuit and weak current circuit; The bottom shell 3 is provided with a mounting hole 31, the mounting hole 31 is used for inserting a mounting screw 32, and the bottom shell 3 is externally mounted through the mounting screw 32; The panel base body 1 is provided with an operation hole 15 at the position corresponding to the mounting hole 31, the screw cap of the mounting screw 32 is exposed to the operation hole 15, and the key 21 covers the operation hole 15, so that when the key 21 is disassembled, the mounting screw 32 can be operated. Wherein, the strong current circuit and the weak current circuit are concentrated on the circuit board 5, the space of the bottom shell 3 can be saved, the volume of the bottom shell 3 is smaller, the bottom shell 3 can be placed in the dark box more conveniently, and the installation convenience of the intelligent switch 100 is improved; Meanwhile, more space is left in the dark box to accommodate other structures, such as wire harness. However, since the strong current circuit and the weak current circuit are arranged on the same circuit board 5, the circuit board 5 cannot be exposed to prevent electric shock. Therefore, the circuit board 5 of the utility model is contained between the panel base body 1 and the bottom shell 3, and the panel base body 1 does not need to be disassembled when the intelligent switch 100 is installed. The mounting hole 31 of the utility model embodiment is arranged in the covered area of the pressing part 2, and the user only needs to disassemble the pressing part 2 when installing the intelligent switch 100, so that the mounting hole 31 is exposed, the mounting screw 32 can be connected to the dark box of the wall, and the intelligent switch 100 is fixed to the wall; The installation process does not need to disassemble the panel base body 1, which protects the circuit board 5 from being damaged and avoids the risk of electric shock caused by the external exposure of the circuit board 5.

[0075] According to the embodiment of the utility model, as Figure 15 、 Figure 17 and Figure 19 shown, since the circuit board provided by the embodiment simultaneously carries strong current and weak current, the circuit board needs to be avoided to be externally exposed in the case of power on. Based on this, in the embodiment, the panel base body 1 comprises a disassembly structure 16 for disassembling the panel base body 1 from the bottom shell 3, the disassembly structure 16 can be operated to disassemble the panel base body 1 from the bottom shell 3, and the disassembly structure 16 is arranged on the back of the panel base body 1, so that when the intelligent switch 100 is installed on the wall, the disassembly structure 16 is hidden between the panel base body 1 and the wall, and the user cannot disassemble the panel base body 1, thereby avoiding that the user mistakenly disassembles the panel base body 1, causing the circuit board 5 to be exposed and existing the risk of electric shock. Wherein, the disassembly structure 16 can be a buckle, a screw or other structure capable of being operated to disassemble the panel base body 1 from the bottom shell 3.

[0076] In an exemplary embodiment, as Figure 15 andFigure 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] According to embodiments of the present invention, such as Figures 15-16 and Figure 11As shown, the number of the circuit board 5 is one, the circuit board 5 is connected with external wires, and is loaded with strong current circuit and weak current circuit, the circuit board 5 is provided with a relay 40, a power supply circuit 50 and the detection piece 52; the power supply circuit 50 is electrically connected to the external wires, and is used for converting alternating current into direct current; the detection piece 52 is used for detecting operation, and the relay 40 is electrically connected to the detection piece 52, and can switch on-off state in response to the detection piece 52 being operated. In a specific embodiment, the lower surface of the circuit board 5 is provided with a plurality of wiring terminals 53, the wiring terminals 53 are connected with zero line, firewire and wires for controlling on-off of the controlled device 200.

[0084] Further, since each of the wiring terminals 53 is to be accommodated in each of the wiring grooves 34, and the position of the locking hole is to correspond to the wiring screw, the relative position accuracy of the wiring terminal 53 and the wiring groove 34 is required to be high, therefore, as shown in Figure 16 and Figure 15 The first positioning hole 54 in strip shape is arranged between each of the wiring terminals 53, the bottom shell 3 is provided with a positioning rib 341 in strip shape between each of the wiring grooves 34, the positioning rib 341 is inserted into the first positioning hole 54, so as to position the bottom shell 3 and the circuit board 5. Wherein, the positioning rib 341 is arranged from bottom to top, so that when the bottom shell 3 is deformed downward, the positioning rib 341 will not affect the circuit board 5.

[0085] Further, as shown in Figure 9 and Figure 11As shown, the detection piece 52 is arranged on the side of the circuit board 5 facing the key 21, the panel base body 1 is provided with a trigger hole 17 at the position corresponding to the detection piece 52, the key 21 is provided with a trigger column 211 facing the detection piece 52, and the trigger column 211 penetrates through the trigger hole 17 and abuts against the detection piece 52. Wherein, the number of the detection piece 52, the trigger column 211 and the trigger hole 17 corresponds to the number of the key 21.

[0086] According to the embodiment of the utility model, as Figure 15 and Figure 18 As shown, the circuit board 5 is fixedly connected to the panel base body 1 through a plurality of fixing screws 554, the bottom shell 3 is provided with an avoiding recess 35 at the position corresponding to the fixing screw 554, the avoiding recess 35 is used for accommodating the nut of the fixing screw 554, so that the circuit board 5 can be close to the bottom shell 3, thereby reducing the thickness of the panel base body. Wherein, the close can be understood as the spacing between the circuit board 5 and the bottom shell 3 is within 2mm, in an embodiment, the circuit board 5 is attached to the upper surface of the bottom shell 3.

[0087] Further, as Figure 11 As shown, the panel base body 1 is provided with two second positioning columns 181, a plurality of second threaded connection holes 182 and three square protrusions 183 facing the circuit board 5, the circuit board 5 is correspondingly provided with a second positioning hole 551, a second connection through hole 552 and a square hole 553, the second positioning column 181 is inserted into the second positioning hole 551, so that the circuit board 5 and the panel base body 1 are positioned;The fixing screw 554 penetrates through the second connection through hole 552 and is connected to the second threaded connection hole 182, so as to fix the circuit board 5 to the panel base body 1;The square hole 553 is used for accommodating the square protrusion 183, the square protrusion 183 is provided with the first clamping position 13, and the square protrusion 183 is hollow, and provides the activity space for the movable clamping structure 243.

[0089] Since the circuit board 5 bears strong current circuit, the strong current on the circuit board 5 has a certain probability to be transmitted to the mounting screw 32 along the surface of the insulating material, therefore, sufficient creepage distance needs to be designed to avoid the current on the circuit board 5 from leaking to the mounting screw 32. The so-called creepage distance is the shortest spatial distance measured along the surface of the insulating material between two conductive components. According to the embodiment of the utility model, as shown in Figure 15 and Figure 13 , the bottom shell 3 is provided with an isolation wall 36 around the mounting hole 31 and towards the panel base 1, the circuit board 5 is arranged outside the isolation wall 36, the isolation wall 36 surrounds the mounting hole 31, and the current on the circuit board 5 needs to climb over 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 avoiding electric shock when the user touches the mounting screw 32.

[0090] The existing switch with display screen generally sets the display screen between the panel base and the transparent cover plate, the panel base limits the side surface of the display screen, the transparent cover plate covers the upper surface of the display screen to fix the display screen, and the transparent cover plate is pasted on the panel base and the display screen. When the display screen needs to be disassembled, the transparent cover plate needs to be disassembled first, and the disassembly difficulty is relatively large; and when there are multiple display screens, the display screen fixing mode is difficult to disassemble one of the display screens without affecting the other display screens, and is not suitable for the intelligent switch with multiple display screens provided by the utility model. Therefore, according to the embodiment of the utility model, as shown in Figure 14 , Figure 11 and Figure 12As shown, the panel base body 1 is provided with a circuit board 5 on the side away from the pressing part 2, the display screen 101 is arranged between the panel base body 1 and the circuit board 5, and the display screen 101 is electrically connected with the circuit board 5; the display screen 101 has a third surface 1011 away from the circuit board 5, and the side surface and the third surface 1011 of the display screen 101 abut against the panel base body 1 respectively, so that the display screen 101 is limited by the panel base body 1; the third surface 1011 is provided with a display area 1012, the panel base body 1 is provided with a display through hole 191 at the position opposite to the display area 1012, the side of the panel base body 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 by the display area 1012 is displayed externally through the display through hole 191 and the transparent cover plate 4. The display screen 101 of the embodiment of the utility model is arranged in the panel base body 1 from the side away from the transparent cover plate 4, and is limited between the panel base body 1 and the circuit board 5, when the display screen 101 is disassembled, only the circuit board 5 needs to be disassembled, and each display screen 101 can be disassembled individually, the display screen 101 will not affect the assembly state of other display screens 101 in the disassembly process, and is more suitable for the structure of the plurality of display screens 101 of the embodiment of the utility model; and the transparent cover plate 4 does not need to be disassembled in the disassembly process, and the disassembly difficulty is reduced.

[0091] Wherein, the display screen 101 abutting against the panel base body 1 can be understood as the display screen 101 directly abutting against the panel base body 1 or indirectly abutting against the panel base body 1 through other structures. Figure 14 As shown, the display screen 101 and the panel base body 1 are provided with a first double-sided adhesive tape (not shown in the figure), the display screen 101 is pasted to the panel base body 1 through the first double-sided adhesive tape, and the first double-sided adhesive tape covers the periphery of the third surface 1011, so that the third surface 1011 is sealingly connected with the lower side of the display through hole 191. Figure 20 As shown, the transparent cover plate 4 is pasted to the upper side of the display through hole 191 through a back adhesive 41, so that the upper and lower sides of the display through hole 191 are respectively sealed by the transparent cover plate 4 and the display screen 101, thereby avoiding dust and water vapor from entering between the transparent cover plate 4 and the display screen 101 and affecting the display effect.

[0092] Further, as shown, Figure 12 The panel base body 1 is provided with an abutting rib 192 around the side surface of the display screen 101, the abutting rib 192 abuts against the side surface of the display screen 101 to limit the side surface of the display screen 101.

[0093] Further, as shown, Figure 11As shown, the circuit board 5 is fixedly connected to the panel base body 1 through a plurality of fixing screws 554, so as to facilitate disassembly of the circuit board 5, thereby facilitating disassembly of the display screen 101. The display screen 101 is connected with the circuit board 5 through a wire 1013, so as to facilitate disconnection of the display screen 101 and the circuit board 5 when the circuit board 5 is disassembled. Thus, the efficiency of replacing the display screen 101 is improved.

[0094] According to the embodiment of the utility model, Figure 14 As shown, the circuit board 5 is provided with a wire connecting terminal 57, the display screen 101 is provided with a wire 1013 facing the third direction, the wire 1013 is inserted into the wire connecting terminal 57 after being bent, the third direction is the direction of the pressing end 23 of the pressing part 2 facing the connecting end 22, and the third direction has been indicated in the Figure 14 The utility model embodiment sets the wire 1013 of the display screen 101 to face the direction away from the key 21, so that the distance between the display screen 101 and the key 21 is closer, the indication effect is better, and the wire 1013 and the pressing part 2 are avoided from being stacked in the thickness direction, thereby reducing the thickness of the intelligent switch 100 and avoiding the movement of the pressing part 2 from driving the wire 1013 to move and causing damage to the wire 1013.

[0095] Further, as shown in Figure 14 and Figure 11 The display screen 101 and the circuit board 5 are provided with a supporting foam 59, the supporting foam 59 provides a supporting force for the display screen 101. The upper end of the supporting foam 59 abuts and is pasted to the display screen 101, and the lower end abuts the circuit board 5, and the supporting foam 59 is in a compressed state, thereby providing a supporting force for the display screen 101, and making the connection between the display screen 101 and the panel base body 1 more stable. The wire connecting terminal 57 is arranged below the supporting foam 59 and is covered by the supporting foam 59, so that the connection between the wire 1013 and the wire connecting terminal 57 is more stable.

[0096] According to the embodiment of the utility model, as shown in Figure 20 and Figure 5 One side of the transparent cover plate 4 facing the panel base body 1 is provided with a light shielding layer 42; the light shielding layer 42 is provided with a display window 421 at the position opposite to the display area 1012, the content displayed by the display area 1012 is displayed externally through the display window 421; wherein the light shielding layer 42 is a black coating layer and is printed on the back of the transparent cover plate 4 by silk printing. The light shielding layer 42 functions to cover the internal structure and improve the appearance. Since the circuit board 5 is provided with strong current circuits and weak current circuits, the display screen 101 is regarded as a live body, and the creepage distance between the display screen 101 and the outer surface of the switch needs to be greater than 2mm to avoid electric shock of the user, and therefore, as shown in 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.

[0097] 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.

[0098] 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.

[0099] According to embodiments of the present invention, such as Figure 11 and Figure 20As shown, the circuit board 5 is provided with an infrared detection device 20, which comprises: an infrared emission unit 201 for emitting a detection wave; an infrared receiving unit 202 for triggering the display screen 101 when the detection wave is received. Wherein, the function of the infrared detection device 20 is to detect the distance between the external object and the smart switch 100, when the distance is close enough, the display screen 101 is triggered. Specifically, the detection wave emitted by the infrared emission unit 201 is transmitted to the infrared receiving unit 202 after being reflected by the external object, the closer the distance between the external object and the infrared receiving unit 202, the stronger the reflected detection wave detected by the infrared receiving unit 202, when the detection wave detected by the infrared receiving unit 202 is greater than a threshold value, the smart switch 100 judges 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. Wherein, the detection wave can be an infrared light wave or other electromagnetic wave. Further, the transparent cover plate 4 covers the infrared emission unit 201 and the infrared receiving unit 202, and the detection wave is detected externally through the transparent cover plate 4.

[0100] The inventor found that the detection wave emitted by the infrared emission unit 201 is easily transmitted from the inside of the smart switch 100 to the infrared receiving unit through two wrong ways, causing the infrared detection device 20 to misjudge, one is that the detection wave is transmitted to the infrared receiving unit 202 through internal total reflection of the transparent cover plate 4; the other is that the detection wave is transmitted to the infrared receiving unit 202 through the gap between the panel base body 1 and the circuit board 5, or when the panel base body 1 is thin and the color is light, the detection wave directly penetrates the panel base body 1 and is transmitted to the infrared receiving unit 202. In order to weaken the two wrong transmission ways, the utility model adopts the following scheme: Figure 20 、 Figure 11 and Figure 6 As shown, the infrared emission unit 201 comprises an infrared light pipe 2012, and the infrared receiving unit 202 comprises an infrared receiving head 2021; at least one display screen 101 is arranged between the infrared light pipe 2012 and the infrared receiving head 2021, so that the distance between the infrared receiving head 2021 and the infrared light pipe 2012 is increased, thereby weakening the internal total reflection of the detection wave in the transparent cover plate 4; the infrared light pipe 2012 is surrounded by a shielding piece 58, which blocks the detection wave on the side of the infrared light pipe 2012, thereby weakening the transmission of the detection wave through the gap between the panel base body 1 and the circuit board 5 or penetrating the panel base body 1 to the infrared receiving unit 202. Through the two schemes, the transmission of the detection wave in the smart switch 100 is weakened, and the misjudgment of the infrared detection device 20 is avoided.

[0101] It is worth mentioning that increasing the distance between the infrared receiving head 2021 and the infrared light emitting tube 2012 can avoid the small objects such as flies and mosquitoes from triggering the infrared detection device 20 to a certain extent. Specifically, when the flies and mosquitoes stop on the surface of the switch, since the size of the flies and mosquitoes is small, the body 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.

[0102] In an embodiment, as shown in FIG. 1, the number of display screens 101 is three, and the three display screens 101 are arranged at intervals along the first direction. The infrared light emitting tube 2012 is arranged between the left display screen 101 and the middle display screen 101, and the infrared receiving head 2021 is arranged between the middle display screen 101 and the right display screen 101. Figure 20

[0103] Further, as shown in FIG. 1, the shielding member 58 is a black ring-shaped foam, which surrounds the infrared light emitting tube 2012. The upper end of the ring-shaped foam abuts against the back adhesive 41 of the transparent cover plate 4, and the lower end abuts against the circuit board 5, so as to block the detection wave from passing through the ring-shaped foam from the side. It is worth noting that since the ring-shaped foam is a flexible material, it can be closely attached to the circuit board 5, avoiding the propagation of the detection wave from the gap between the ring-shaped foam and the circuit board 5. Further, the panel base body 1 is provided with a transmission through hole 193 and a receiving through hole 194 at the positions corresponding to the ring-shaped foam and the infrared receiving head 2021. The transmission through hole 193 accommodates and limits the ring-shaped foam, and the receiving through hole 194 accommodates the infrared receiving head 2021. Figure 6 Figure 11 Figure 20 Further, as shown in FIG. 1, the shielding member 58 is a black ring-shaped foam, which surrounds the infrared light emitting tube 2012. The upper end of the ring-shaped foam abuts against the back adhesive 41 of the transparent cover plate 4, and the lower end abuts against the circuit board 5, so as to block the detection wave from passing through the ring-shaped foam from the side. It is worth noting that since the ring-shaped foam is a flexible material, it can be closely attached to the circuit board 5, avoiding the propagation of the detection wave from the gap between the ring-shaped foam and the circuit board 5. Further, the panel base body 1 is provided with a transmission through hole 193 and a receiving through hole 194 at the positions corresponding to the ring-shaped foam and the infrared receiving head 2021. The transmission through hole 193 accommodates and limits the ring-shaped foam, and the receiving through hole 194 accommodates the infrared receiving head 2021.

[0104] Further, as shown in FIG. 1, the shielding member 58 is a black ring-shaped foam, which surrounds the infrared light emitting tube 2012. The upper end of the ring-shaped foam abuts against the back adhesive 41 of the transparent cover plate 4, and the lower end abuts against the circuit board 5, so as to block the detection wave from passing through the ring-shaped foam from the side. It is worth noting that since the ring-shaped foam is a flexible material, it can be closely attached to the circuit board 5, avoiding the propagation of the detection wave from the gap between the ring-shaped foam and the circuit board 5. Further, the panel base body 1 is provided with a transmission through hole 193 and a receiving through hole 194 at the positions corresponding to the ring-shaped foam and the infrared receiving head 2021. The transmission through hole 193 accommodates and limits the ring-shaped foam, and the receiving through hole 194 accommodates the infrared receiving head 2021. Figure 20 Figure 5 ​​​​As shown, the light shielding layer 42 is provided with an emission window 422 opposite to the infrared emitting tube 2012, and is provided with a receiving window 423 opposite to the infrared receiving head 2021, the infrared receiving head 2021 receives external detection waves through the receiving window 423, and the infrared emitting tube 2012 emits detection waves to the outside 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 emitting tube 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 greater the distance between the infrared emitting tube 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. The detection angle of the infrared detection device 20 can be accurately controlled by controlling the size of the emission window 422 and the distance between the infrared emitting tube 2012 and the transparent cover plate 4. The detection angle of the infrared detection device 20 is controlled to be less than 90° in the embodiment of the utility model, because when the detection angle is too large, the infrared detection device 20 is easy to be triggered by mistake. When the detection angle is too small, the user is easy to not trigger the intelligent switch 100 when approaching from the side, therefore, the inventors verify by experiment that the detection angle is controlled to be 30°-60°, so as to reach the appropriate trigger range.

[0105] Further, as shown in the figure, Figure 20 the back adhesive 41 of the transparent cover plate 4 is provided with a first back adhesive hole 411, a second back adhesive hole 412 and a third back adhesive hole 413 opposite to the display window 421, the emission window 422 and the receiving window 423 respectively, and the sizes of the first back adhesive hole 411, the second back adhesive hole 412 and the third back adhesive hole 413 are greater than those of the display window 421, the emission window 422 and the receiving window 423 respectively.

[0106] In another embodiment, as shown in the figure, Figure 22 the difference between this embodiment and the Figures 1-21 embodiment is that the plug-in structure 241 is relatively loose with the plug-in position 11, when the key 21 is pressed, the pressing part 2 will be pivoted based on the first pivot 121, the plug-in structure 241 no longer provides a reset force, and the reset foam 29 is arranged between each key 21 and the panel base 1, and the reset force is provided through the reset foam 29. Compared with the spring, the foam has the characteristic of slow rebound, and the use of the foam to provide the reset force can make the pressing feeling of the key 21 have a damping feeling, and the pressing feeling is more advanced. Further, the lower surface of the key 21 is provided with a foam mounting position 291, and the reset foam 29 is pasted to the foam mounting position 291. Further, in the first direction, both sides of each key 21 are provided with a reinforcing rib position for reinforcing the rigidity of the key 21.

[0107] Further, as shown in Figure 22 , each side of the key 21 adjacent to other keys 21 is provided with a thinning slope 261 for thinning the thickness of the edge of the key 21, so that the thickness of the key 21 near the connecting structure 25 is thinned, thereby reducing the linkage effect between the keys 21, i.e. the movement of one key 21 will not drive the adjacent other keys 21 to move. Moreover, the key 21 is provided with the thinning slope 261, which can also increase the width of the injection mold at this position, so that this position is not easy to damage the corresponding injection mold. Specifically, if the key 21 is not provided with the thinning slope 261, the injection mold at the position corresponding to the split seam 26 will be in an elongated strip shape, which is easy to damage. The thinning slope 261 thins the thickness of the key 21 at the position corresponding to the split seam 26, and correspondingly, the injection mold at this position is widened, thereby increasing the strength of the injection mold.

[0108] In another embodiment, as shown in Figure 23 , the transparent cover plate 4 is not shown in the figure, and this embodiment is a two-key version of the intelligent switch 100. The difference between this embodiment and the Figures 1-21 embodiment is that the number of keys 21 is 2, and correspondingly, the number of display screens 101, relays 40, detection pieces 52, trigger holes 17 and trigger columns 211 is 2 respectively. 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 weakening the total reflection of the detection wave inside the transparent cover plate 4, and avoiding the 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 body 1 is provided with the display through hole 191, the emission through hole 193 and the receiving through hole 194 at positions corresponding to 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 emission window 422 and the receiving window 423 on the light shielding layer 42 correspond to the positions of the display through hole 191, the emission through hole 193 and the receiving through hole 194 respectively. Each key 21 is provided with a movable clamping structure 243, and the number and positions of the first clamping positions 13 of the panel base body 1 are the same as those of the three-key version of the intelligent switch 100, which are all 3, and the first clamping positions 13 on the left and right sides of the panel base body 1 are clamped to the movable clamping structures 243 of the two keys 21 respectively.

[0109] In another embodiment, as shown in Figure 24 , the transparent cover plate 4 is not shown in the figure, and this embodiment is a single-key version of the intelligent switch 100. The difference between this embodiment and the Figures 1-21The difference of the embodiment is that the number of the key 21 is one, and the number of the display screen 101, the relay 40, the detection piece 52, the trigger hole 17 and the trigger column 211 is one respectively. The infrared light emitting tube 2012 is arranged at the left side of the display screen 101, and the infrared receiving head 2021 is arranged at 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 weakening the total reflection of the detection wave inside the transparent cover plate 4, and avoiding the 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 display through hole 191, the emission through hole 193 and the receiving through hole 194 are respectively arranged at the positions corresponding to the display area 1012 of the display screen 101, the infrared light emitting tube 2012 and the infrared receiving head 2021 of the panel base body 1. The positions of the display window 421, the emission window 422 and the receiving window 423 on the light shielding layer 42 correspond to the positions of the display through hole 191, the emission through hole 193 and the receiving through hole 194. The key 21 is provided with two movable clamping structures 243, and the number and positions of the first clamping positions 13 of the panel base body 1 are the same as those of the three-key version of the intelligent switch 100, that is, three first clamping positions 13 are arranged on the left and right sides of the panel base body 1, and the two movable clamping structures 243 of the key 21 are clamped to the first clamping positions 13.

[0110] In addition, the existing intelligent wall switch generally has at least one circuit board fixedly connected to the bottom shell. When the bottom shell is installed on the wall, the bottom shell is easily deformed towards the inside of the wall due to the too tight installation screw, and the circuit board will be deformed along with the bottom shell. When the deformation amount of the bottom shell is too large, the circuit board may be damaged. Based on this, the utility model also provides an intelligent switch to solve the above problems. In this embodiment, the drawings are shared with the drawings of the above-mentioned embodiments.

[0111] As shown in Figure 18 and Figure 15 , the intelligent switch 100 comprises a bottom shell 3, a panel base body 1 and at least one circuit board 5, the panel base body 1 covers the bottom shell 3; each of the circuit boards 5 is fixedly connected to the panel base body 1, and the opposite sides of the bottom shell 3 are provided with mounting holes 31 for external installation, and the two sides of the bottom shell 3 which are not provided with the mounting holes 31 are connected to the panel base body 1, so that when the bottom shell 3 is deformed during installation, the deformation amount of the panel base body 1 and the circuit board 5 following the deformation of the bottom shell 3 is reduced. Wherein, the technical details of the bottom shell 3, the panel base body 1 and the circuit board 5 have been described in detail above, and will not be repeated here. Figure 18 It is a sectional view of the simplified structure of the intelligent switch 100. Figure 18The first drawing is a structural schematic diagram of the bottom shell 3 before deformation, and the second drawing is a structural schematic diagram of the bottom shell 3 after deformation, and it can be seen from the drawings that when the bottom shell 3 deforms towards the inside of the wall, since the panel base body 1 is connected to the left and right ends of the bottom shell 3, and the mounting screws 32 are arranged on the two sides of the bottom shell 3 which are not connected to the panel base body 1, the deformation of the bottom shell 3 caused by the mounting screws 32 has less effect on the panel base body 1, and the left and right ends of the bottom shell 3 abut against the wall, further reducing the effect of the deformation of the bottom shell 3 on the panel base body 1. Since each circuit board 5 is connected to the panel base body 1 and not directly connected to the bottom shell 3, the effect of the deformation of the bottom shell 3 on the circuit board 5 is very small, thereby avoiding damage to the circuit board 5.

[0112] Further, the number of the circuit board 5 is one, the circuit board 5 is connected to an external wire and carries a strong current circuit and a weak current circuit, the circuit board 5 is provided with a relay 40, a power supply circuit 50 and a detection piece 52; the power supply circuit 50 is electrically connected to the external wire and is used for converting alternating current into direct current; the detection piece 52 is used for detecting operation, and the relay 40 is electrically connected to the detection piece 52 and can switch on and off in response to the detection piece 52 being operated. The operation can be a pressing operation or a touch operation, when the operation is the pressing operation, the detection piece 52 can be a detection switch, a touch switch, a micro switch, a thin film switch, a Hall, etc., and can be triggered in response to the pressing operation; when the operation is the touch operation, the detection piece 52 can be a capacitive touch sensing module, etc., and can be triggered in response to the touch operation. The technical details of the detection piece 52, the relay 40 and the power supply circuit 50 are described in detail above, and will not be repeated here. The strong current circuit and the weak current circuit in the utility model are concentrated on one circuit board 5, which can save the space of the bottom shell 3, make the volume of the bottom shell 3 smaller, make the bottom shell 3 more conveniently placed in the dark box, and improve the installation convenience of the intelligent switch 100; at the same time, more space is left in the dark box to accommodate other structures, such as a wire harness.

[0113] The existing intelligent switch generally fixes a strong current circuit board to a bottom shell, and the bottom shell is prone to deformation towards the inside of the wall when installed in the wall, causing the strong current circuit board to move towards the inside of the wall. The strong current circuit and the weak current circuit in the utility model are concentrated on the same circuit board, and then the detection piece is arranged on the circuit board, if the circuit board moves towards the inside of the wall, the gap between the key and the detection piece will be larger, and the key cannot trigger the detection piece. To solve this problem, according to the embodiment of the utility model, Figure 6 and Figure 9As shown, the intelligent switch 100 further comprises a button 21 abutting the detection piece 52 for receiving a pressing operation and triggering the detection piece 52 in response to the pressing operation; wherein the button 21 is connected to the panel base 1, so that when the bottom shell 3 deforms, the relative position relationship between the circuit board 5 and the button 21 is not affected too much, and then the button 21 can also trigger the detection piece 52 when the bottom shell 3 deforms. The connection structure 25 of the button 21 and the panel base 1 has been described in detail above, and will not be repeated here. The detection piece 52 is preferably a tactile switch.

[0114] According to the embodiment of the utility model, the bottom shell 3 does not provide direct fixing constraint for the circuit board 5, to further reduce the influence of the deformation of the bottom shell 3 on the circuit board 5.

[0115] According to the embodiment of the utility model, as shown in Figure 13 and Figure 9 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 circuit board 5 is detached from the bottom shell 3 along with the panel base 1, and then in the assembly process, the circuit board 5 only needs to be fixed to the panel base 1, and the bottom shell 3 can be quickly and conveniently buckled to the panel base 1 to complete the assembly, improving the assembly efficiency. Further, the panel base 1 and the bottom shell 3 form a containing cavity, the circuit board 5 is contained in the containing cavity, and the circuit board 5 carries strong current circuit and weak current circuit; the panel base 1 comprises a detachment structure 16 for detaching the panel base 1 from the bottom shell 3, and the detachment structure 16 is arranged on the back of the panel base 1, so that when the intelligent switch 100 is installed on the wall, the detachment structure 16 is hidden between the panel base 1 and the wall. Since the strong current circuit and the weak current circuit are arranged on the same circuit board 5 in the utility model, the circuit board 5 cannot be exposed to prevent electric shock. Therefore, 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 detached when the intelligent switch 100 is installed. Since the detachment structure 16 is hidden between the panel base 1 and the wall, the user cannot detach the panel base 1, thereby avoiding that the user mistakenly detaches the panel base 1, causing the circuit board 5 to be exposed and having the risk of electric shock. The technical details of the panel base 1, the bottom shell 3 and the detachment structure 16 have been described in detail above, and will not be repeated here.

[0116] In an exemplary embodiment, as Figure 15 and Figure 17As shown, the dismounting structure 16 comprises a second buckle 161, the bottom shell 3 is provided with a second buckling position 33 matched with the second buckle 161, the second buckle 161 is buckled in the second buckling position 33, the second buckle 161 can be pried to make the panel base 1 dismount from the bottom shell 3; wherein the second buckle 161 is integrally formed in the inner side of the side wall of the panel base 1, the second buckling position 33 is arranged 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.

[0117] In another exemplary embodiment, as shown in Figure 19 the dismounting structure 16 comprises a connecting screw 162, the left end of the panel base 1 is buckled in the bottom shell 3, and the right end is provided with a threaded connection hole matched with the connecting screw 162; the bottom shell 3 is provided with a counterbore matched with the threaded connection hole, the connecting screw 162 is connected to the threaded connection hole through the counterbore to realize the detachable connection of the panel base 1 and the bottom shell 3; wherein the counterbore is arranged on the side of the bottom shell 3 abutting the wall, and the counterbore 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.

[0118] According to the embodiment of the present application, as shown in Figure 15 and Figure 18 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 recess 35 at a position corresponding to the fixing screw 554, the recess 35 is used to accommodate the nut of the fixing screw 554, so that the circuit board 5 can be close to the bottom shell 3, thereby reducing the thickness of the panel base. Wherein, the technical details of the recess 35 are described in detail above, and will not be repeated here.

[0119] According to the embodiment of the present application, as shown in Figure 15 and Figure 16 the side of the circuit board 5 away from the panel base 1 is provided with a wireless communication module 56, the circuit board 5 is not laid with copper foil at a position corresponding to the wireless communication module 56, so that the wireless signal can pass through the circuit board 5, avoiding the shielding of the wireless signal by the circuit board 5.

[0120] Since the circuit board 5 bears strong current circuit, the strong current on the circuit board 5 has a certain probability to be transmitted to the mounting screw 32 along the surface of the insulating material, therefore, sufficient creepage distance needs to be designed to avoid the current on the circuit board 5 from leaking to the mounting screw 32. The so-called creepage distance is the shortest spatial distance measured between two conductive components along the surface of the insulating material. According to the embodiment of the utility model, as shown in Figure 15 and Figure 13 The mounting hole 31 is used for inserting the mounting screw 32, and the bottom shell 3 is externally mounted through the mounting screw 32; the bottom shell 3 is provided with an isolation wall 36 around the mounting hole 31 and towards the panel base body 1, the circuit board 5 is arranged outside the isolation wall 36, the isolation wall 36 surrounds the mounting hole 31, and the current on the circuit board 5 needs to jump over 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 avoiding electric shock caused by the user touching the mounting screw 32.

[0121] It is obvious for those skilled in the art that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the utility model is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model.
