Detailed Implementation

[0037] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0038] This application provides an electronic wall switch, which refers to a unit that uses a combination of control boards and electronic components and programming to achieve intelligent circuit switching control. The electronic wall switch is a new type of home appliance that is safer and more practical, based on the electronic processing of ordinary wall switches. A cable tray is embedded inside the wall, and the electronic wall switch is fixedly installed in the cable tray. Compared to existing wall switches, the electronic wall switch does not require moving and stationary contacts, which can reduce the thickness of the electronic wall switch and better meet current aesthetic requirements.

[0039] like Figures 1-16 As shown, the electronic wall switch of this application includes a cover plate 1, a pressure plate 2, a circuit board 3, and a switch base 4. The cover plate 1, pressure plate 2, and switch base 4 are stacked sequentially. The circuit board 3 is disposed inside the switch base 4, and at least one micro switch 31 is disposed on the circuit board 3. At least one pressing member 32 is disposed between the cover plate 1 and the circuit board 3. The pressure plate 2 is provided with at least one first through hole 21. At least one pressing member 32 passes through at least one first through hole 21 and acts on at least one micro switch 31. The switch base 4 includes an integrally formed mounting part 41 and a base box 42. The mounting part 41 is relative to the base box. 42 has a protrusion, and the protrusion of the mounting part 41 is provided with a second mounting hole 45 for mounting with the cable tray box. A metal plate 5 is embedded in the mounting part 41. The metal plate 5 has a similar structure to the mounting part 41. The metal plate 5 is located between the mounting part 41 and the pressure plate 2. A second through hole 51 for the circuit board 3 to pass through is provided in the middle of the metal plate 5. A first mounting hole 52 is provided on two opposite sides of the metal plate 5 for the first mounting screw to pass through. The first mounting hole 52 and the second mounting hole 45 correspond to each other. The first mounting screw can pass through the first mounting hole 52 and the second mounting hole 45 to fix the metal plate 5 and the switch base 4 on the cable tray box.

[0040] The electronic wall switch provided by this utility model has a higher structural strength by embedding a metal plate 5 inside the mounting part 41 of the switch base 4. The metal plate 5 is located between the pressure plate 2 and the switch base 4, making the electronic wall switch less prone to deformation during installation. The metal plate 5 is preferably made of steel plate, but other metal materials, such as iron plate and copper plate, are also within the scope of protection of this application.

[0041] in, Figure 2 A longitudinal sectional view of the electronic wall switch of this application is shown. Figure 3 A cross-sectional view of the electronic wall switch of this application is shown.

[0042] Preferred, such as Figure 4 and Figure 5 As shown, the metal plate 5 has a square frame structure. Furthermore, in this embodiment, the two opposite sides of the metal plate 5 extend into the middle part of the metal plate 5 to form a first limiting boss 53, and the first mounting hole 52 is formed on the first limiting boss 53.

[0043] Preferred, such as Figure 1 , Figure 6 and Figure 7 As shown, the mounting part 41 has a square frame structure. A third through hole 43 for the circuit board 3 to pass through is provided in the middle of the mounting part 41. Two opposite sides of the mounting part 41 extend into the middle of the mounting part 41 to form second limiting bosses 44. The second mounting hole 45 is provided on the second limiting bosses 44.

[0044] Preferred, such as Figure 8 and Figure 9 As shown, the pressure plate 2 has a square structure, and a fourth through hole 22 is provided on each of the opposite sides of the pressure plate 2. The fourth through hole 22 corresponds to the first mounting hole 52 and the second mounting hole 45. The fourth through hole 22 allows the first mounting screw to be removed and the switch base 4 to be removed from the wire trough box without disassembling the pressure plate 2.

[0045] Furthermore, such as Figure 1 As shown, the pressure plate 2 includes two fixing plugs 23, which are respectively embedded in two fourth through holes 22. Setting the fixing plugs 23 to block the fourth through holes 22 can prevent foreign objects from entering and improve the safety of the electronic wall switch.

[0046] Furthermore, such as Figure 10 and Figure 11 As shown, the fixing plug 23 includes an integrally formed blocking part 231 and a snap-fit ​​part 232. The snap-fit ​​part 232 includes two snap-fit ​​legs arranged opposite each other, and the two snap-fit ​​legs are provided with barbs. The fixing plug 23 is inserted into the fourth through hole 22 from the front of the pressure plate 2, and the two snap-fit ​​legs are engaged with the back of the pressure plate 2. Here, the front and back refer only to two different sides of the pressure plate 2, and do not specifically refer to which side is the front and which side is the back.

[0047] Preferred, such as Figure 1 , Figure 12 and Figure 13 As shown, at least one light-emitting element 33 is provided on the circuit board 3, and at least one pressing element 32 of the electronic wall switch is installed inside at least one first through hole 21. The at least one pressing element 32 corresponds to the position of at least one light-emitting element 33, as shown. Figure 14 As shown, at least one display window 11 is provided on the cover plate 1, and at least one display window 11 corresponds to at least one pressing member 32.

[0048] The light-emitting element 33 may be, but is not limited to, an LED light. Preferably, the pressing element 32 in this application is a light-transmitting elastic pressing element made of light-transmitting elastic material, which can simultaneously play the roles of elastic reset and light guide post, eliminating the need for a separate light guide post.

[0049] Preferably, the pressing component 32 in this application is a light-transmitting silicone pad. The silicone pad is elastic, soft to the touch, and transparent, allowing it to act as a light guide to transmit the light source of the light-emitting component 33. When the microswitch 31 is triggered, the light-emitting component 33 illuminates, and the pressing component 32 can signal to the outside world that it is in operation. Simultaneously, the silicone pad can be tightly fitted into the first through hole 21, facilitating easy installation and removal. Figure 15 and Figure 16 A structural schematic diagram of the front and back of the pressing member 32 is shown. On the other hand, since the silicone pad is elastic, after the silicone pad is forced to drive the micro switch 31 to act, the silicone pad returns to its original shape, driving the cover plate 1 to reset, replacing the reset member in the prior art, saving internal space of the electronic wall switch, reducing the size of the electronic wall switch. The display window 11 can exist in the form of a through hole, or it can be provided with a transparent cover, or a silicone pad can also be provided in the through hole.

[0050] Furthermore, such as Figure 14 , Figure 15 and Figure 16 As shown, at least one driving part 12 is provided on the side of the cover plate 1 facing the pressure plate 2. The at least one driving part 12 corresponds to at least one pressing member 32. The driving part 12 is a boss extending from the side of the cover plate 1 facing the pressure plate 2. The pressing member 32 is provided with a driving groove or driving hole that cooperates with the driving part 12. The driving part 12 can extend into the driving groove or driving hole of the pressing member 32 to press the cover plate 1. The driving part 12 acts on the micro switch 31 through the pressing member 32 or directly acts on the micro switch 31 through the pressing member 32. The driving part 12 is close to the display window 11, and the driving part 12 and the display window 11 correspond to the pressing member 32 at the same time. Compared with the existing technology, only the first through hole 21 is provided on the pressure plate 2. The first through hole 21 is used to install the pressing member 32. The pressing member 32 is made of silicone material. It can be used to guide the light to the cover plate 1 and to drive the micro switch 31 of the drive unit 12. It achieves two goals at once and saves process steps and production time.

[0051] It should be noted that when the driving hole is opened on the pressing member 32, the connection position between the driving part 12 and the cover plate 1 is thickened to form a driving boss. When the driving part 12 passes through the driving hole and acts on the micro switch 31, the driving boss abuts against the pressing member 32, causing the pressing member 32 to deform. After releasing the force, the pressing member 32 releases energy to push the driving boss to reset the cover plate 1.

[0052] In a preferred embodiment of this application, the pressing member 32 is provided with the driving groove. When the cover plate 1 is pressed, the driving part 12 on the cover plate 1 extends into the driving groove, and the bottom of the driving groove contacts the micro switch 31. Since the pressing member 32 of this application is a light-transmitting silicone pad, it has a soft touch and a better pressing experience.

[0053] Preferably, four microswitches 31 are spaced apart on the circuit board 3, and light-emitting elements 33 are respectively arranged near the four microswitches 31. Four first through holes 21 are correspondingly arranged on the pressure plate 2. Four pressing elements 32 are arranged between the cover plate 1 and the circuit board 3. Four display windows 11 are correspondingly arranged on the pressure plate 2.

[0054] Furthermore, the cover plate 1 includes multiple first cover plates 18 arranged side by side. Each first cover plate 18 has at least two display windows 11, and the at least two display windows 11 correspond to at least two pressing elements 32. The at least two pressing elements 32 correspond to at least two micro switches 31 and at least two light-emitting elements 33. Setting at least two micro switches 31 can produce better tactile feedback and more sensitive response when pressing the cover plate 1, and setting at least two light-emitting elements 33 can produce better light guiding effect.

[0055] Furthermore, such as Figure 1 As shown in the embodiment of this application, the cover plate 1 includes two first cover plates 18 arranged side by side. Each first cover plate 18 has two display windows 11 spaced apart. The two display windows 11 correspond to two pressing members 32. The two pressing members 32 correspond to two micro switches 31 and two light-emitting members 33. In a preferred embodiment, two first through holes 21 are spaced apart in the middle of the pressure plate 2. The pressing members 32 are arranged inside the two first through holes 21. The two pressing members 32 correspond to the connection positions of the two first cover plates 18. The additional two pressing members 32 can produce a better light guiding effect.

[0056] Preferred, such as Figure 8 , Figure 9 and Figure 14 As shown, the cover plate 1 has two latches 13 spaced apart on the side facing the pressure plate 2. Each latch 13 includes two latch arms with a latch groove between them. The pressure plate 2 has a corresponding locking shaft 14, which is installed in the latch groove. The two latch arms clamp the locking shaft 14, allowing the cover plate 1 and the pressure plate 2 to rotate and be fixed together. The latch structure allows the cover plate 1 and the pressure plate 2 to be rotated and fixed together, which reduces the gap between them and thus reduces the thickness of the electronic switch.

[0057] Furthermore, such as Figure 1 , Figure 8 and Figure 9As shown, the cover plate 1 includes two first cover plates 18 arranged side by side. The locking shafts 14 extend from both sides of the pressure plate 2. Two locking holes 15 or two locking slots are provided at intervals in the middle of the pressure plate 2. The locking shafts 14 are disposed in the locking holes 15 or locking slots. One first cover plate 18 corresponds to one locking shaft 14 extending to one side and one locking shaft 14 disposed in the locking hole 15 or locking slot. The buckle 13 extends into the locking hole 15 or locking slot. The rotation axis of the cover plate 1 is located in the plane of the pressure plate 2. Lowering the position of the rotation axis of the cover plate can reduce the thickness of the electronic wall switch.

[0058] Preferred, such as Figure 6 , Figure 7 , Figure 12 and Figure 13 As shown, the circuit board 3 has multiple parallel terminal blocks 34. The base box 42 of the switch base 4 has terminal block slots 35 corresponding to each of the terminal blocks 34. Insulating partitions 36 are provided between the terminal block slots 35. The circuit board 3 has first fixing holes 37 for fixing the insulating partitions 36 and second fixing holes 38 for installing the terminal blocks 34. The insulating partitions 36 between the terminal block slots 35 enhance the insulation performance between the terminal blocks 34 and prevent phase-to-phase short circuits. The insulating partitions 36 can be integrally formed with the switch base 4, reducing the manufacturing process and improving production efficiency. In this embodiment, the terminal blocks 34 are located on the side of the circuit board 3 facing the base box 42.

[0059] Furthermore, such as Figure 7 As shown, a through hole 46 is provided on the back of the terminal block slot 35 for connecting external cables. In this embodiment, the circuit board 3 is provided with six terminals 34.

[0060] Furthermore, such as Figure 12 and Figure 13 As shown, the circuit board 3 is provided with two first clearance areas 39 that are recessed towards the center of the circuit board 3. The two first clearance areas 39 correspond to the two second limiting protrusions 44 of the switch base 4 and are used to avoid the two second limiting protrusions 44. At the same time, the two second limiting protrusions 44 limit the circuit board 3.

[0061] Furthermore, such as Figure 7As shown, the base box 42 is provided with two second relief areas 47 that are recessed towards the center of the base box 42. The two second relief areas 47 correspond to the two first relief areas 39 respectively. That is, the first mounting hole 52 of the metal plate 5, the second mounting hole 45 on the mounting part 41 of the switch base 4, the first relief area 39 and the second relief area 47 correspond one-to-one. The first mounting screw can be passed through the first mounting hole 52 and the second mounting hole 45 and the wire trough box for fixing. The first relief area 39 and the second relief area 47 can avoid the first mounting screw.

[0062] Preferred, such as Figure 6 , Figure 7 and Figure 9 As shown, the pressure plate 2 is provided with a first buckle 16 on the side facing the switch base 4, and the switch base 4 is provided with a first buckle hole 17 that cooperates with the first buckle 16. The structure of the first buckle 16 is that the pressure plate 2 extends with a boss in the direction facing the switch base 4, and a barb is formed on the boss. The first buckle 16 extends into the first buckle hole 17 from the front of the switch base 4, and the barb on the first buckle 16 hooks onto the back of the switch base 4.

[0063] Furthermore, in this embodiment, the pressure plate 2 is provided with the first buckle 16 at each of its four corners, and the connection position between the mounting part 41 of the switch base 4 and the base box 42 is provided with four first buckle holes 17 corresponding to the first buckle 16. The circuit board 3 is placed inside the base box 42, the metal plate 5 is embedded in the mounting part 41 of the switch base 4, the pressure plate 2 is fixedly connected to the switch base 4 through the first buckle 16, the pressure plate 2 presses against the circuit board 3, and the pressure plate 2 and the switch base 4 clamp and fix the metal plate 5.

[0064] It should be noted that existing electronic wall switches are relatively thick, which does not meet market aesthetic demands. The mounting portion 41 of the electronic wall switch in this application has a mounting groove. A metal plate 5 and a pressure plate 2 are sequentially installed in the mounting groove. The pressure plate 2 is fixedly installed to the switch base 4. The mounting groove and the pressure plate 2 clamp and fix the metal plate 5. A cover plate 1 is rotatably installed on the pressure plate 2. The cover plate 1 and the mounting portion 41 have the same structural size. The cover plate 1 covers the switch base 4 and the mounting portion 41, covering the pressure plate 2 and concealing the mounting groove. This structure can reduce the thickness of the electronic wall switch, making its structure more aesthetically pleasing.

[0065] Furthermore, a first force-bearing part 54 is formed by protruding on the side of the second through hole 51 of the metal plate 5 facing the pressure plate 2, and a second force-bearing part 55 is formed by protruding on the side of the pressure plate 2 facing the metal plate 5. Through the cooperation of the second force-bearing part and the first force-bearing part 54, the pressure plate 2 can limit and fix the metal plate 5.

[0066] Furthermore, in this embodiment, the first force-receiving part 54 and the second force-receiving part 55 are strip-shaped, which can produce a better contact effect.
