Description

Technical Field

[0001] This application relates to the field of switch technology, specifically to a wall switch. Background Technology

[0002] A wall switch is an electrical switch that is installed on a wall. A wall switch typically includes a mounting bracket, electrical components, a panel, and buttons. The electrical components, panel, and buttons are all mounted on the mounting bracket, which is then installed on the wall and electrically connected to the circuit to realize the function of the wall switch.

[0003] Currently, some wall switches adopt a narrow bezel panel design. However, due to the limitations of the narrow bezel panel's own structural design, its structural strength is relatively weak. It is prone to deformation to varying degrees due to external forces or the release of its own stress, which can easily lead to gaps in the assembly between the panel and the mounting bracket, affecting the assembly stability of the wall switch.

[0004] Therefore, there is an urgent need to propose a wall switch to solve the problems existing in the current technology. Utility Model Content

[0005] The purpose of this application is to provide a wall switch that improves the assembly stability between the panel and the mounting bracket.

[0006] This application provides a wall switch, including a mounting bracket and a panel frame. The mounting bracket has a continuous first protrusion, a second protrusion, a third protrusion, and a fourth protrusion on its periphery. The first protrusion has a first positioning groove on its inner side, the second protrusion has a second positioning groove on its inner side, the third protrusion has a third positioning groove on its inner side, and the fourth protrusion has a fourth positioning groove on its inner side.

[0007] The panel frame includes a continuous first frame, a second frame, a third frame and a fourth frame. The first frame has a first limiting boss in the middle, the second frame has a second limiting boss in the middle, the third frame has a third limiting boss in the middle, and the fourth frame has a fourth limiting boss in the middle.

[0008] The panel frame is fixedly connected to the mounting bracket by a snap-fit ​​structure. The first limiting boss is inserted into the first positioning groove, the second limiting boss is inserted into the second positioning groove, the third limiting boss is inserted into the third positioning groove, and the fourth limiting boss is inserted into the fourth positioning groove.

[0009] The four edges of the panel frame are respectively matched with the corresponding positioning slots on the mounting bracket by corresponding limiting bosses, so that the middle of each edge can fit against the periphery of the mounting bracket, avoiding gaps between the panel frame and the mounting bracket due to deformation of one or more edges of the panel frame, thereby improving the assembly stability between the panel frame and the mounting bracket.

[0010] In some examples, the button is provided with a first support and a second support, a first receiving part is provided on the first limiting boss, a second receiving part is provided on the third limiting boss, the first support is connected to the first receiving part, and the second support is connected to the second receiving part.

[0011] The first receiving part corresponds to the first support part that receives the button, and the second receiving part corresponds to the second support part that receives the button, so as to provide stable support for the button. By setting the first receiving part on the first limiting boss and the second receiving part on the third limiting boss, the assembly stability between the button and the panel frame can be improved while achieving stable assembly of the panel frame to the mounting bracket, effectively solving the problem of assembly gaps between the panel frame and the button caused by the deformation of the panel frame.

[0012] In some examples, the first receiving portion includes a first extension plate angled to the first limiting boss, and a first limiting groove disposed on the first extension plate, with a first support portion limitedly connected to the first limiting groove. The second receiving portion includes a second extension plate angled to the third limiting boss, and a second limiting groove disposed on the second extension plate, with a second support portion limitedly connected to the second limiting groove.

[0013] By providing a first extension plate and a first limiting groove on the first extension plate, the position of the first support part can be restricted while providing support points for the first support part, thereby further improving the support reliability provided by the first receiving part. Similarly, by providing a second extension plate and a second limiting groove on the second extension plate, the position of the second support part can be restricted while providing support points for the second support part, thereby further improving the support reliability of the second receiving part.

[0014] In some examples, the mounting bracket is also provided with a first mounting slot and a second mounting slot. The first mounting slot is connected to a first positioning slot, and a first receiving part is installed in the first mounting slot. The second mounting slot is connected to a third positioning slot, and a second receiving part is installed in the second mounting slot.

[0015] The first mounting groove is used to position and install the first receiving part and to provide support for the first receiving part. The second mounting groove is used to position and install the second receiving part and to provide support for the second receiving part, which can improve the load-bearing capacity of the first and second receiving parts.

[0016] In some examples, the first frame has a first side plate opposite to the first limiting boss, the second frame has a second side plate opposite to the second limiting boss, the third frame has a third side plate opposite to the third limiting boss, and the fourth frame has a fourth side plate opposite to the fourth limiting boss. The first side plate, the second side plate, the third side plate, and the fourth side plate abut against the periphery of the mounting bracket.

[0017] By setting side plates on the four edges of the panel frame, the first side plate and the first limiting boss can clamp and fix it to the first protruding edge, the second side plate and the second limiting boss can clamp and fix it to the second protruding edge, the third side plate and the third limiting boss can clamp and fix it to the third protruding edge, and the fourth side plate and the fourth limiting boss can clamp and fix it to the fourth protruding edge. This further reduces the possibility of gaps appearing in the assembly of the panel frame on the mounting frame due to deformation, and enhances the assembly stability of the panel frame on the mounting frame.

[0018] In some examples, the snap-fit ​​structure includes a first snap-fit ​​groove disposed on the outer side of the second protrusion, a second snap-fit ​​groove disposed on the outer side of the fourth protrusion, a first snap-fit ​​boss disposed on the second side plate, and a second snap-fit ​​boss disposed on the fourth side plate. The first snap-fit ​​boss is snapped into the first snap-fit ​​groove, and the second snap-fit ​​boss is snapped into the second snap-fit ​​groove.

[0019] The panel frame and mounting bracket are fixedly connected by a combination of snap-fit ​​bosses and snap-fit ​​grooves, featuring a simple structure, easy assembly, and high assembly stability. Furthermore, by providing snap-fit ​​grooves on both the symmetrical second and fourth protruding edges, and snap-fit ​​bosses on the corresponding second and fourth side plates, snap-fit ​​fixing can be achieved simultaneously from two symmetrical positions, ensuring the panel frame is stably mounted on the mounting bracket.

[0020] In some examples, a first guide groove is provided on the outer side of the second protrusion, and a second guide groove is provided on the outer side of the fourth protrusion. The first snap-fit ​​boss can move along the first guide groove to snap into the first snap-fit ​​groove, and the second snap-fit ​​boss can move along the second guide groove to snap into the second snap-fit ​​groove.

[0021] The first guide groove facilitates the first snap-fit ​​boss to snap into the first snap-fit ​​slot, enabling quick and accurate connection. Similarly, the second guide groove facilitates the second snap-fit ​​boss to snap into the second snap-fit ​​slot, enabling quick and accurate snap-fit ​​between the second snap-fit ​​boss and the second snap-fit ​​slot.

[0022] In some examples, the ends of the first limiting boss, the second limiting boss, the third limiting boss, and the fourth limiting boss are all provided with guide ramps.

[0023] By setting a guide slope at the end of the limiting boss, the limiting boss can slide relative to the groove wall of the positioning groove during the insertion process when it is inserted into the corresponding positioning groove, so as to achieve smooth assembly.

[0024] In some examples, the mounting bracket has screw holes spaced apart, and the side of the screw holes near the center of the mounting bracket has a pre-deformation groove.

[0025] The pre-deformation groove provides deformation space for the mounting bracket. When the mounting bracket is fixed to the wall by screws and screw fastening holes, it will deform due to excessive force. The pre-deformation groove can reduce the deformation range of the mounting bracket, thereby reducing the impact on the structure and assembly of the panel frame, buttons and electrical connections.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] In wall switches with narrow bezel panels, the structural strength of the narrow bezel panel itself is limited, which makes it easy for the narrow bezel panel to deform during production and assembly. This can result in large assembly gaps in the finished wall switch, affecting the overall assembly stability of the wall switch.

[0047] Based on this, the present application provides a wall switch that can improve the assembly stability between the panel and the mounting bracket.

[0048] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0049] Reference Figures 1 to 6 This embodiment provides a wall switch 100, including a mounting bracket 1 and a panel frame 2.

[0050] The mounting bracket 1 in the wall switch 100 is used to fix and assemble other components of the wall switch 100, such as the panel frame 2, button 3, electrical components, etc., and the mounting bracket 1 is used to fix and install it to a specific position on the wall, while connecting the wall switch 100 to the circuit to realize the normal use of the wall switch 100.

[0051] The panel frame 2 in the wall switch 100 is installed on the surface of the mounting bracket 1, which can provide corresponding protection for part of the structure of the mounting bracket 1 or other components assembled on the mounting bracket 1, and reduce the possibility of external factors such as dust and moisture entering the interior of the wall switch 100 and causing damage to the wall switch 100.

[0052] Reference Figures 2 to 4 The mounting bracket 1 has a continuous first protrusion 11, a second protrusion 12, a third protrusion 13 and a fourth protrusion 14 on its periphery. The first protrusion 11 has a first positioning groove 111 inside, the second protrusion 12 has a second positioning groove 121 inside, the third protrusion 13 has a third positioning groove 131 inside, and the fourth protrusion 14 has a fourth positioning groove 141 inside.

[0053] Reference Figures 2 to 4 The panel frame 2 includes a continuous first frame 21, a second frame 22, a third frame 23 and a fourth frame 24. The first frame 21 has a first limiting boss 211 in the middle, the second frame 22 has a second limiting boss 221 in the middle, the third frame 23 has a third limiting boss 231 in the middle, and the fourth frame 24 has a fourth limiting boss 241 in the middle.

[0054] Reference Figures 2 to 6 The panel frame 2 is fixedly connected to the mounting bracket 1 by a snap-fit ​​structure. The first limiting boss 211 is inserted into the first positioning groove 111, the second limiting boss 221 is inserted into the second positioning groove 121, the third limiting boss 231 is inserted into the third positioning groove 131, and the fourth limiting boss 241 is inserted into the fourth positioning groove 141.

[0055] Specifically, the mounting bracket 1 includes two parts: a main mounting plate 15 and an electrical connection part 16. The main mounting plate 15 is used to mount the panel frame 2 and to the wall. The electrical connection part 16 is located in the middle of the main mounting plate 15 and protrudes from the side of the main mounting plate 15 away from the mounting panel frame 2. The electrical connection part 16 is used to connect to an external circuit and to connect the button 3.

[0056] The main mounting plate 15 is typically designed as a quadrilateral. The first protruding edge 11, the second protruding edge 12, the third protruding edge 13 and the fourth protruding edge 14 are continuously arranged around the periphery of the main mounting plate 15. The structure of the protruding edges is such that the edge of the main mounting plate 15 protrudes to the side away from the direction where the electrical connection part 16 is located, and finally encloses the edge of the main mounting plate 15 to form a quadrilateral annular groove.

[0057] The panel frame 2 is formed by the first border 21, the second border 22, the third border 23 and the fourth border 24 to form a quadrilateral frame that matches the shape of the main mounting plate 15. The four borders of the panel frame 2 are installed on the four protruding edges of the main mounting plate 15 to achieve partial coverage of the mounting bracket 1 by the panel frame 2.

[0058] Among them, reference Figures 3 to 7The first frame 21 has a first limiting boss 211 in the middle and a first positioning groove 111 corresponding to the first limiting boss 211 on the first protruding edge 11. When the first frame 21 is assembled to the first protruding edge 11, the first limiting boss 211 is inserted into the first positioning groove 111. At this time, the middle part of the first frame 21 can be restricted to a position that fits against the first protruding edge 11, so as to reduce the possibility of gaps between the first frame 21 and the first protruding edge 11 due to deformation. Even if the first frame 21 has a small amount of deformation, the first frame 21 and the first protruding edge 11 can be kept in close contact and stably assembled through the cooperation of the first limiting boss 211 and the first positioning groove 111.

[0059] The first positioning groove 111 can be disposed on the surface of the first protruding edge 11, or it can be in the form of a blind hole disposed on the first protruding edge 11. In this embodiment, the first positioning groove 111 is disposed on the surface of the first protruding edge 11 and located inside the first protruding edge 11. The first limiting boss 211 is engaged inside the first protruding edge 11 to limit the deformation of the first frame 21 in a direction away from the first protruding edge 11, so that the first frame 21 can be fitted and assembled with the first protruding edge 11. This design has the advantages of simple structure and easy processing and assembly.

[0060] Reference Figures 3 to 7 The first limiting boss 211 is a protruding structure on the side of the first frame 21 near the main mounting plate 15 of the mounting bracket 1, and the protrusion direction of the first limiting boss 211 faces the main mounting plate 15. When the panel frame 2 is fastened to the main mounting plate 15, the first limiting boss 211 can be inserted into the first positioning groove 111 along the fastening direction of the panel frame 2 to achieve accurate matching with the first positioning groove 111.

[0061] In addition, the number of first positioning grooves 111 can be two or more, and multiple first positioning grooves 111 are arranged at intervals on the inner side of the first protrusion 11. At the same time, the number of first limiting bosses 211 is set to correspond one-to-one with the first positioning grooves 111. The cooperation of multiple first limiting bosses 211 and multiple first positioning grooves 111 is conducive to further improving the assembly stability of the first frame 21 on the first protrusion 11.

[0062] The matching forms of the second positioning groove 121 with the second limiting boss 221, the third positioning groove 131 with the third limiting boss 231, and the fourth positioning groove 141 with the fourth limiting boss 241 are all the same as the matching forms of the first positioning groove 111 with the first limiting boss 211, and have the corresponding technical effects, which will not be elaborated here.

[0063] The four edges of the panel frame 2 are respectively engaged with the corresponding positioning grooves on the mounting bracket 1 through corresponding limiting bosses, so that the middle of each edge can fit against the periphery of the mounting bracket 1, avoiding gaps between the panel frame 2 and the mounting bracket 1 due to deformation of one or more edges of the panel frame 2, thereby improving the assembly stability between the panel frame 2 and the mounting bracket 1.

[0064] In some examples, refer to Figure 8 and Figure 9 The button 3 is provided with a first support part 31 and a second support part 32. The first limiting boss 211 is provided with a first receiving part 212, and the third limiting boss 231 is provided with a second receiving part 232. The first support part 31 is connected to the first receiving part 212, and the second support part 32 is connected to the second receiving part 232.

[0065] The first receiving part 212 receives the first support part 31 of the button 3, and the second receiving part 232 receives the second support part 32 of the button 3, so as to provide stable support for the button 3. By setting the first receiving part 212 on the first limiting boss 211 and the second receiving part 232 on the third limiting boss 231, the assembly stability between the button 3 and the panel frame 2 can be improved while achieving stable assembly of the panel frame 2 to the mounting bracket 1, effectively solving the problem of assembly gaps between the panel frame 2 and the button 3 caused by deformation of the panel frame.

[0066] In the wall switch 100 with a narrow bezel panel, the button 3 is usually a large flat button 3. The side of the button 3 near the mounting bracket 1 has a connection structure for connecting with the electrical connection part 16 to realize the switching function.

[0067] Reference Figure 9 The first support portion 31 and the second support portion 32 are also disposed on the side near the mounting frame 1, and the first support portion 31 and the second support portion 32 are symmetrically arranged. Specifically, the first support portion 31 and the second support portion 32 are designed as arc-shaped bosses, and the protrusion direction of the arc-shaped bosses faces the mounting frame 1.

[0068] The first limiting boss 211 and the third limiting boss 231 are also in symmetrical positions. The first receiving part 212 is integrally formed with the first limiting boss 211, and the second receiving part 232 is integrally formed with the third limiting boss 231. This ensures that the first receiving part 212 remains fixed after the first limiting boss 211 is engaged with the first positioning groove 111, and the second receiving part 232 remains fixed after the third limiting boss 231 is engaged with the third positioning groove 131, thereby ensuring that the button 3 can receive stable and reliable support.

[0069] Furthermore, referring to Figures 8 to 12The first receiving portion 212 includes a first extension plate 2121 angled to the first limiting boss 211, and a first limiting groove 2122 disposed on the first extension plate 2121. The first support portion 31 is limitedly connected to the first limiting groove 2122. The second receiving portion 232 includes a second extension plate angled to the third limiting boss 231, and a second limiting groove disposed on the second extension plate. The second support portion 32 is limitedly connected to the second limiting groove.

[0070] By providing a first extension plate 2121 and a first limiting groove 2122 on the first extension plate 2121, the position of the first support part 31 can be restricted while providing support points for the first support part 31, thereby further improving the support reliability provided by the first receiving part 212. Similarly, by providing a second extension plate and a second limiting groove on the second extension plate, the position of the second support part 32 can be restricted while providing support points for the second support part 32, thereby further improving the support reliability of the second receiving part 232.

[0071] Specifically, refer to Figure 10 The first extension plate 2121 is angled to the first limiting boss 211, typically at 90°. This means the first extension plate 2121 is perpendicular to the first limiting boss 211, and its extension direction is from the first limiting boss 211 toward the third limiting boss 231. A first limiting groove 2122 is located on the surface of the first extension plate 2121, specifically on the side of the first extension plate 2121 facing the button 3. The first limiting groove 2122 is an arc-shaped groove that matches the arc-shaped boss of the first support portion 31. This design allows the first limiting groove 2122 to provide a limiting function for the first support portion 31 while reducing interference. It also facilitates assembly and allows the button 3 to smoothly swing to achieve the switching operation.

[0072] Similarly, the second extension plate and the third limiting boss 231 are designed at a 90° angle, that is, the second extension plate is perpendicular to the third limiting boss 231, and the extension direction of the second extension plate is based on the third limiting boss 231 towards the first limiting boss 211. The second limiting groove is provided on the surface of the second extension plate, specifically located on the side of the second extension plate facing the button 3. The second limiting groove is designed as an arc-shaped groove that matches the arc-shaped boss of the second support part 32. This design of the second limiting groove can reduce interference while providing a limiting function for the second support part 32, and can allow the button 3 to swing smoothly to achieve the switch operation while facilitating assembly.

[0073] Additionally, refer to Figure 10The two side walls of the first limiting groove 2122 are also designed to be arc-shaped, matching the rounded corners at the bottom of the arc-shaped boss. This facilitates assembly while reducing interference between the first limiting groove 2122 and the first support part 31. The second limiting groove is designed in the same way as the first limiting groove 2122, which facilitates assembly while reducing interference between the second limiting groove and the second support part 32.

[0074] In some examples, refer to Figure 11 and Figure 12 The mounting bracket 1 is also provided with a first mounting groove 151 and a second mounting groove 152. The first mounting groove 151 is connected to the first positioning groove 111. The first receiving part 212 is installed in the first mounting groove 151. The second mounting groove 152 is connected to the third positioning groove 131. The second receiving part 232 is installed in the second mounting groove 152.

[0075] The first mounting groove 151 is provided for positioning and installing the first receiving part 212 and for supporting the first receiving part 212. The second mounting groove 152 is provided for positioning and installing the second receiving part 232 and for supporting the second receiving part 232. This can improve the load-bearing capacity of the first receiving part 212 and the second receiving part 232.

[0076] Specifically, refer to Figure 12 The first mounting groove 151 is connected to the first positioning groove 111. When the first limiting boss 211 is inserted into the first positioning groove 111, the first receiving part 212 enters the first mounting groove 151. The side of the first receiving part 212 that is away from the first limiting groove 2122 can abut against the bottom of the first mounting groove 151. This can provide support for the first receiving part 212, which is beneficial to improve the load-bearing capacity of the first receiving part 212 and reduce the possibility of deformation of the first receiving part 212 due to excessive force.

[0077] The second mounting groove 152 is connected to the third positioning groove 131. While the third limiting boss 231 is inserted into the third positioning groove 131, the second receiving part 232 enters the second mounting groove 152. The side of the second receiving part 232 that is away from the second limiting groove can abut against the bottom of the second mounting groove 152. This provides support for the second receiving part 232, which helps to improve the load-bearing capacity of the second receiving part 232 and reduces the possibility of deformation of the second receiving part 232 due to excessive force. Together with the first receiving part 212 and the first mounting groove 151, it can be used in situations where a large force is applied.

[0078] Compared to the traditional wall switch 100 where the first support portion 31 and the second support portion 32 of the button 3 directly act on the mounting bracket 1, this embodiment supports the first support portion 31 through the cooperation of the first mounting groove 151 and the first receiving portion 212, and supports the second support portion 32 through the cooperation of the second mounting groove 152 and the second receiving portion 232. Even if the mounting bracket 1 deforms during assembly, causing the first mounting groove 151 to separate from the first receiving portion 212, or causing the second mounting groove 152 to separate from the second receiving portion 232, the first receiving portion 212 and the second receiving portion 232 can still ensure that the positions of the first support portion 31 and the second support portion 32 remain unchanged, thereby keeping the position of the button 3 fixed, avoiding affecting normal switch operation, and improving the stability of the wall switch 100.

[0079] In some examples, refer to Figures 3 to 7 The first frame 21 is provided with a first side plate 213 opposite to the first limiting boss 211, the second frame 22 is provided with a second side plate 222 opposite to the second limiting boss 221, the third frame 23 is provided with a third side plate opposite to the third limiting boss 231, and the fourth frame 24 is provided with a fourth side plate 242 opposite to the fourth limiting boss 241. The first side plate 213, the second side plate 222, the third side plate and the fourth side plate 242 are respectively abutted against the periphery of the mounting bracket 1.

[0080] By providing side plates on the four edges of the panel frame 2, it can be clamped and fixed to the first protruding edge 11 by the first side plate 213 and the first limiting boss 211, clamped and fixed to the second protruding edge 12 by the second side plate 222 and the second limiting boss 221, clamped and fixed to the third protruding edge 13 by the third side plate and the third limiting boss 231, and clamped and fixed to the fourth protruding edge 14 by the fourth side plate 242 and the fourth limiting boss 241. This further reduces the possibility of gaps appearing in the assembly of the panel frame 2 on the mounting bracket 1 due to deformation, and enhances the assembly stability of the panel frame 2 on the mounting bracket 1.

[0081] Specifically, refer to Figure 7 The first side plate 213 and the first limiting boss 211 are arranged opposite to each other, and there is a gap between the first side plate 213 and the first limiting boss 211. When the first frame 21 is assembled to the first protruding edge 11, the first limiting boss 211 is inserted into the first positioning groove 111 provided on the inner side of the first protruding edge 11, and the first side plate 213 is parallel to the outer side of the first protruding edge 11. The first side plate 213 and the first limiting boss 211 form a clamping relationship to achieve the assembly effect of clamping the first frame 21 on the first protruding edge 11, thereby effectively reducing the possibility of assembly gap between the first frame 21 and the mounting bracket 1 due to deformation of the first frame 21.

[0082] Correspondingly, the assembly of the second side plate 222 and the second limiting boss 221 on the second protruding edge 12, the assembly of the third side plate and the third limiting boss 231 on the third protruding edge 13, and the assembly of the fourth side plate 242 and the fourth limiting boss 241 on the fourth protruding edge 14 are the same as the assembly of the first side plate 213 and the first limiting boss 211 on the first protruding edge 11, thereby effectively improving the assembly stability between each frame on the panel frame 2 and the mounting bracket 1.

[0083] In some examples, refer to Figure 3 and Figure 4 The snap-fit ​​structure includes a first snap-fit ​​groove 122 disposed on the outer side of the second protrusion 12, a second snap-fit ​​groove 142 disposed on the outer side of the fourth protrusion 14, a first snap-fit ​​boss 2221 disposed on the second side plate 222, and a second snap-fit ​​boss disposed on the fourth side plate 242. The first snap-fit ​​boss 2221 is snapped into the first snap-fit ​​groove 122, and the second snap-fit ​​boss is snapped into the second snap-fit ​​groove 142.

[0084] The panel frame 2 and the mounting bracket 1 are fixedly connected by a combination of snap-fit ​​bosses and snap-fit ​​grooves, which features a simple structure, easy assembly, and high assembly stability. Furthermore, by providing snap-fit ​​grooves on the symmetrical second protrusion 12 and fourth protrusion 14, and snap-fit ​​bosses on the corresponding second side plate 222 and fourth side plate 242, snap-fit ​​fixing can be achieved simultaneously from two symmetrical positions, ensuring that the panel frame 2 is stably installed on the mounting bracket 1.

[0085] The first snap-fit ​​groove 122 is located on the outer side of the second protrusion 12, and the first snap-fit ​​boss 2221 is located on the side of the second side plate 222 close to the second protrusion 12. During the assembly of the second frame 22 and the second protrusion 12, the second limiting boss 221 is inserted into the second positioning groove 121, and the first snap-fit ​​boss 2221 is snapped into the first snap-fit ​​groove 122. This achieves both the fixed assembly and position limitation of the second frame 22 and the second protrusion 12, resulting in high assembly convenience.

[0086] Correspondingly, the second snap-fit ​​groove 142 is located on the outer side of the fourth protrusion 14, and the second snap-fit ​​boss is located on the side of the fourth side plate 242 close to the fourth protrusion 14. During the assembly of the fourth frame 24 and the fourth protrusion 14, the fourth limiting boss 241 is inserted into the fourth positioning groove 141, and the second snap-fit ​​boss is snapped into the second snap-fit ​​groove 142, thereby achieving the fixed assembly and position limitation of the fourth frame 24 and the fourth protrusion 14.

[0087] In one optional embodiment, multiple first snap-fit ​​bosses 2221 can be provided, and the multiple first snap-fit ​​bosses 2221 are arranged at intervals on the second side plate 222. Multiple first snap-fit ​​grooves 122 are also provided, and the multiple first snap-fit ​​grooves 122 are engaged one-to-one with the multiple first snap-fit ​​bosses 2221. Increasing the number of snap-fit ​​engagements can further improve assembly stability. The same applies to the second snap-fit ​​bosses and the second snap-fit ​​grooves 142.

[0088] In another alternative embodiment, a similar snap-fit ​​structure can also be provided between the first protruding edge 11 and the first side plate 213, and a similar snap-fit ​​structure can also be provided between the third protruding edge 13 and the third side plate. This allows for snap-fit ​​fixing in all four directions, which helps to eliminate the assembly gap between the panel frame 2 and the mounting bracket 1 caused by deformation, and significantly improves assembly stability.

[0089] In some examples, refer to Figure 3 and Figure 4 The outer side of the second protrusion 12 is also provided with a first guide groove 123, and the outer side of the fourth protrusion 14 is also provided with a second guide groove 143. The first snap-fit ​​boss 2221 can move along the first guide groove 123 to snap into the first snap-fit ​​groove 122, and the second snap-fit ​​boss can move along the second guide groove 143 to snap into the second snap-fit ​​groove 142.

[0090] The first guide groove 123 facilitates the first snap-fit ​​boss 2221 to snap-fit ​​groove 122, enabling quick and accurate connection. Similarly, the second guide groove 143 facilitates the second snap-fit ​​boss to snap-fit ​​groove 142, enabling quick and accurate snap-fit ​​between the second snap-fit ​​boss and the second snap-fit ​​groove 142.

[0091] The first guide groove 123 is located on the outside of the second protruding edge 12 and on the side of the second protruding edge 12 closer to the button 3. The first snap-fit ​​groove 122 is located on the outside of the second protruding edge 12 and on the side of the second protruding edge 12 away from the button 3. When the second frame 22 is fastened to the second protruding edge 12, the first snap-fit ​​boss 2221 can be aligned with the first guide groove 123 and slide along the first guide groove 123 so that the position of the first snap-fit ​​boss 2221 can undergo a slight deformation so that the first snap-fit ​​boss 2221 can move smoothly and snap into the first snap-fit ​​groove 122.

[0092] Similarly, the second guide groove 143 is disposed on the outer side of the fourth protrusion 14 and located on the side of the fourth protrusion 14 closer to the button 3, and the second snap-fit ​​groove 142 is disposed on the outer side of the fourth protrusion 14 and located on the side of the fourth protrusion 14 away from the button 3. When the fourth frame 24 is fastened to the fourth protrusion 14, the second snap-fit ​​boss can be aligned with the second guide groove 143 and slide along the second guide groove 143, so that the position of the second snap-fit ​​boss can undergo a slight deformation, so that the second snap-fit ​​boss can move smoothly and snap into the second snap-fit ​​groove 142.

[0093] In some examples, refer to Figure 7 The ends of the first limiting boss 211, the second limiting boss 221, the third limiting boss 231, and the fourth limiting boss 241 are all provided with guide slopes.

[0094] By setting a guide slope at the end of the limiting boss, the limiting boss can slide relative to the groove wall of the positioning groove during the insertion process when it is inserted into the corresponding positioning groove, so as to achieve smooth assembly.

[0095] The guide ramp on the first limiting boss 211 is located on the side of the first limiting boss 211 near the first side plate 213, and the guiding direction of the guide ramp is from the end of the first limiting boss 211 toward the root of the first limiting boss 211. The second limiting boss 221, the third limiting boss 231 and the fourth limiting boss 241 are all the same as the first limiting boss 211 and have the same technical effect, so they will not be described in detail here.

[0096] In some examples, refer to Figure 2 , Figure 11 and Figure 13 The mounting bracket 1 is provided with screw fixing holes 17 at intervals, and the screw fixing holes 17 are provided with pre-deformation grooves 18 on the side near the middle of the mounting bracket 1.

[0097] The pre-deformation groove 18 provides deformation space for the mounting bracket 1. When the mounting bracket 1 is fixed to the wall by screws and screw fastening holes, the mounting bracket 1 will deform due to excessive force. The pre-deformation groove 18 can reduce the deformation range of the mounting bracket 1, thereby reducing the impact on the structure and assembly of the panel frame 2, button 3 and electrical connection part 16.

[0098] Two screw fastening holes are provided, which are symmetrically arranged on the main mounting plate 15 and located on both sides of the electrical connection part 16. Two pre-deformation grooves 18 are provided, and both pre-deformation grooves 18 are located between the screw fastening holes and the electrical connection part 16.

[0099] When the mounting bracket 1 is subjected to a large clamping force, the deformation generated by the mounting bracket 1 will be concentrated at the pre-deformation groove 18, causing the pre-deformation groove 18 to undergo corresponding deformation, thereby reducing the possibility of deformation of the electrical connection part 16, and further reducing the risk of damage to the electrical components in the electrical connection part 16, which is beneficial to improving the structural stability and safety of the wall switch 100.

[0100] In some examples, refer to Figure 13 The first groove wall 181 in the pre-deformation groove 18 is inclined and extends to the second groove wall 182 opposite to the first groove wall 181. The second groove wall 182 is provided with a relief slope 1821, and the inclination direction of the relief slope 1821 is the same as the inclination direction of the first groove wall 181.

[0101] The pre-deformation groove 18 is set at an angle, which can reduce the impact of deformation of the mounting bracket 1, and at the same time reduce the possibility of dust or water vapor and other impurities entering the wall switch 100 from the pre-deformation groove 18, further improving the protective effect of the wall switch 100, and helping the wall switch 100 to maintain structural stability and electrical safety.

[0102] Specifically, the pre-deformation groove 18 is designed as a long strip. The first groove wall 181 of the pre-deformation groove 18 is inclined towards the second groove wall 182, and the second groove wall 182 is provided with a corresponding avoidance slope 1821 to cooperate with the second groove wall 182, so that the groove opening of the pre-deformation groove 18 forms an acute angle with the plane where the main mounting plate 15 is located. With this design, when the mounting bracket 1 is subjected to a large clamping force, the first groove wall 181 of the pre-deformation groove 18 will deform along the inclined direction towards the side closer to the second groove wall 182, thereby reducing the risk of damage to the electrical connection part 16 located on the side of the second groove wall 182 away from the first groove wall 181. At the same time, the inclined groove opening can effectively reduce the possibility of dust or moisture entering, reducing the risk of electrical accidents caused by the wall switch 100 being affected.

[0103] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
