Technical Field

[0001] The present application relates to the field of switch technology, and in particular to an ultra-thin wall switch. Background Art

[0002] A wall switch is an electrical switch mounted on a wall to connect and disconnect circuits. Traditional wall switches are often bulky, which limits the flexibility of interior design. To meet users' dual needs for aesthetics and practicality, ultra-thin wall switches have become a market trend.

[0003] Chinese patent number CN215955159U discloses an ultra-thin wall switch, including a button, a rotating member, a driving member and a toggle member; the button is fixedly connected to the rotating member, the rotating member and the driving member are interconnected, and the upper end surfaces of the driving member and the toggle member are in contact with each other; when the button is pressed, the button and the rotating member rotate and drive the driving member to rotate. During the rotation of the driving member, the upper end surface of the toggle member is pressed / released to control the swing of the toggle member, thereby controlling the closing or opening of the wall switch.

[0004] The above-mentioned ultra-thin wall switch has the advantage of ensuring normal circuit on and off while rotating at a small angle, but it contains many small-sized parts inside. During the automated assembly process, the positioning accuracy required for assembly is high, and problems are prone to occur during the automated assembly process, which is not conducive to the realization of automated assembly. Utility Model Content

[0005] In order to facilitate automated assembly, the present application provides an ultra-thin wall switch.

[0006] The present application provides an ultra-thin wall switch that adopts the following technical solution:

[0007] An ultra-thin wall switch, comprising:

[0008] A base, the base is provided with a groove, a lift piece is rotatably connected to the bottom of the groove, and a static contact piece group for contacting the lift piece is fixedly connected to the bottom of the groove;

[0009] A face frame, comprising a reinforcement frame fixedly connected to the top of the base and a frame fixedly connected to the reinforcement frame;

[0010] An angle magnification component, the angle magnification component includes a mounting base fixedly connected to the inside of the groove, a swinging member rotatably connected to the mounting base, and a pressure plate located above the swinging member, a swing rod for pressing the lifter is provided at the bottom of the swinging member, the swing rod is passed through the mounting base, a buckle arm is connected to the top of the mounting base, the swinging member is provided with a positioning hole for the buckle arm to pass through, the pressure plate is provided with a buckling portion for the buckle arm to buckle, the swinging member is provided with a positioning groove, and the positioning grooves are located on both sides of the swing rod;

[0011] The switch panel is rotatably connected to the top of the pressure plate, and the bottom of the switch panel is connected to a clamping arm for inserting into the positioning groove, and the clamping arm is used to drive the rocker to rotate.

[0012] By employing this technical solution, the angle magnification assembly effectively increases the travel of the swing arm, ensuring that the lifter is pressed to activate the static contact assembly. A positioning slot facilitates the positioning and assembly of the clamp arm. Inserting the clamp arm into the positioning slot ensures that the swing arm is centered, allowing the clamp arm to swing. The angle magnification assembly is divided into three components, enabling layered installation of the entire switch, facilitating automated assembly and significantly improving assembly efficiency.

[0013] Optionally, a positioning protrusion is provided on the inner wall of the positioning groove close to the rocker arm side, and a clamping block is provided on the end of the clamping arm close to the rocker arm side, and the clamping block abuts against the positioning protrusion.

[0014] By adopting the above technical solution, during installation, the clamping block abuts against the positioning protrusion so that the clamping arm can stably hold the positioning protrusion, ensuring that when the switch panel is pressed, the clamping arm can stably drive the rocker arm to swing, thereby ensuring the stability of the switch operation.

[0015] Optionally, a guide surface is provided on a side of the positioning protrusion close to the switch panel.

[0016] By adopting the above technical solution, during assembly, the guide surface can effectively guide the clamping portion of the clamping arm to abut against the positioning protrusion, thereby effectively improving assembly efficiency.

[0017] Optionally, two opposite ends of the swinging member are connected to rotating blocks, and two ends of the top of the mounting seat are provided with rotating seats that are buckled with and rotatably connected to the rotating blocks.

[0018] By adopting the above technical solution, the rotating block can cooperate with the rotating seat to realize the rotational connection of the swinging part. During installation, the rotating block is inserted into the rotating seat and buckled to achieve effective positioning and facilitate assembly.

[0019] Optionally, a receiving groove is opened inside the rocker arm, a sliding head for pressing the lifter is connected to the opening of the receiving groove, a spring is arranged between the top wall of the receiving groove and the sliding head, and a fixing block for fixing one end of the spring is connected to the inner wall of the receiving groove, and the fixing blocks are respectively located on both sides of the spring.

[0020] By adopting the above technical solution, the spring can effectively abut the sliding head, so that when the rocker arm rotates, the restoring force generated by the elastic deformation of the spring pushes the sliding head to abut the lifter, thereby ensuring that the switch can achieve the operation of switching the circuit.

[0021] Optionally, a positioning column for the spring to be sleeved is provided on the side of the sliding head away from the lifter.

[0022] This technical solution facilitates spring positioning and installation, and the positioning post effectively secures the spring. During use, the spring's released elastic potential energy fully acts on the slider, ensuring it always abuts the lifter. The positioning post facilitates spring positioning and securing during assembly, improving assembly efficiency.

[0023] Optionally, a rotating shaft is passed through the middle of the pressure plate, and a clamp arm for clamping the rotating shaft is connected to the bottom of the switch panel, and the distance from the axis of the rotating shaft to the center of the rocker arm is greater than the distance from the axis of the rotating block to the center of the rocker arm.

[0024] By employing this technical solution, the clamp arms effectively clamp the shaft and achieve a rotational connection, allowing the switch panel to rotate about the shaft, thereby adjusting the on / off state of the circuit. Multiple clamp arms clamp the shaft, ensuring the stability of the switch panel after assembly. The distance from the shaft to the center of the swing arm is longer than the distance from the rotating block to the center of the swing arm. This allows the swing arm at the bottom to rotate at a greater angle when the switch panel rotates, ensuring that the paddle can rotate to achieve the on / off state of the circuit.

[0025] Optionally, the inner wall of the frame is connected to a fixed shaft for clamping by the clamp arm, and the axis of the fixed shaft is colinear with the axis of the rotating shaft.

[0026] By adopting the above technical solution, when the switch panel is pressed, the fixed shaft can evenly transfer the panel pressure to the frame, thereby achieving uniform force on the switch panel and improving its service life.

[0027] Optionally, a clamping arm is connected to the inner wall of the groove, and the pressure plate is provided with a clamping groove for the clamping arm to be engaged, and the clamping groove is located on both sides of the rotating shaft.

[0028] By adopting the above technical solution, the pressing plate can be fixed by the base and the mounting seat at the same time, thereby ensuring the stability of the overall structure after assembly.

[0029] Optionally, the pressing plate is fixedly connected to the frame.

[0030] By adopting the above technical solution, the pressure plate and the surface frame are fixedly connected to achieve further simplification of the structure, facilitate the production and manufacturing of parts and the assembly of switches, and improve production efficiency.

[0031] In summary, this application has the following beneficial effects:

[0032] 1. By setting the angle magnification component, the rocker arm can still have a large rotation angle when the switch panel is rotated at a small angle, so that the travel of the sliding head on the lifter can still meet the requirements of the switch on and off, thereby improving the stability of use.

[0033] 2. By dividing the angle magnification component into three components: a mounting base, a swinging part, and a pressing plate, layered assembly is achieved, making automated assembly easier. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-8 This application is described in further detail.

[0044] Example 1 of the present application discloses an ultra-thin wall switch. Figure 1 、 Figure 2 and Figure 3 The ultra-thin wall switch includes a base 1, a face frame 2 fixedly connected to the base 1, an angle magnification component 3 disposed within the base 1, and a switch panel 4 rotatably connected to the angle magnification component 3. The face frame 2 includes a reinforcement frame 21 fixedly connected to the top of the base 1 and a frame 22 fixedly connected to the reinforcement frame 21. The base 1 has a groove 11, a tilting piece 12 rotatably connected to the bottom of the groove 11, and a static contact piece group 13 fixedly connected to the bottom of the groove 11 for contact with the tilting piece 12. By pressing the switch panel 4, the angle magnification component 3 can drive the tilting piece 12 to rotate, causing the contact point of the tilting piece 12 to open and close with the contact point of the static contact piece group 13, thereby changing the power state of the switch.

[0045] Reference Figure 3 、 Figure 4 and Figure 5 The angle magnification assembly 3 includes a mounting base 31 fixedly connected to the interior of the groove 11, a swinging member 32 rotatably connected to the top of the mounting base 31, and a pressure plate 33 located above the swinging member 32 and buckled with the mounting base 31. The bottom edge of the pressure plate 33 abuts the top of the reinforcement frame 21. The bottom of the swinging member 32 is provided with a swing rod 34 that penetrates the mounting base 31 and is used to press the tilting tab 12. A snap arm 311 is fixedly connected to the top of the mounting base 31. The swinging member 32 defines a positioning hole 321 for the snap arm 311 to pass through. The pressure plate 33 defines a snapping portion 331 for the snap arm 311 to buckle.

[0046] During assembly, the mounting base 31 is first fixed inside the groove 11 of the base 1, and then the swing member 32 and the pressure plate 33 are installed on the top of the mounting base 31 in sequence. The snap arm 311, the positioning hole 321 and the snap-fitting part 331 cooperate with each other to realize the layered installation of the angle magnification component 3, which facilitates automated assembly and improves installation efficiency.

[0047] Reference Figure 3 、 Figure 4 and Figure 5 The switch panel 4 has two clamping arms 41 connected to the bottom, which are used to control the swing lever 34. The swing member 32 has two positioning slots 322 for the clamping arms 41 to insert into. The two positioning slots 322 are located on either side of the swing lever 34. During assembly, the positioning slots 322 facilitate the positioning of the clamping arms 41 and clamping of the swing lever 34, thereby facilitating assembly and improving assembly efficiency. They also ensure that the swing lever 34 is located between the clamping arms 41 on both sides, allowing the clamping arms 41 to drive the swing lever 34 to swing, thereby improving the stability of the switch during use.

[0048] Reference Figure 3 、 Figure 4 and Figure 5 The inner wall of the positioning slot 322 near the rocker 34 is provided with a positioning protrusion 323, which is located at the bottom of the positioning slot 322. Clamping blocks 411 are located at the ends of the clamping arms 41 on the side near the rocker 34. The clamping blocks 411 abut against the positioning protrusion 323, and the positioning protrusion 323 is provided with a guide surface 3231 on the side near the switch panel 4. When the clamping arms 41 are inserted into the positioning slot 322, guided by the guide surface 3231, the clamping blocks 411 can move along the guide surface 3231 and abut against the positioning protrusion 323, thereby ensuring that the clamping arms 41 can effectively clamp the positioning protrusion 323. When the switch panel rotates, at least one side of the clamping arms 41 can always abut against the positioning protrusion 323, thereby driving the rocker 34 to rotate, improving the stability of the switch and ensuring the accuracy during assembly, thereby improving assembly precision.

[0049] Reference Figure 3 、 Figure 4 and Figure 5 The bottom wall of the swing arm 34 is provided with a receiving groove 341. A slider 35 for pressing the lift tab 12 is inserted into the opening of the receiving groove 341. A spring 36 is disposed within the receiving groove 341. One end of the spring 36 abuts the slider 35, and the other end abuts the top wall of the receiving groove 341. When the swing arm 34 swings, the restoring force generated by the elastic deformation of the spring 36 effectively pushes the slider 35 against the lift tab 12, thereby ensuring that the switch can achieve circuit switching operation and improving user stability.

[0050] Reference Figure 3 、 Figure 4 and Figure 5The inner wall of the receiving groove 341 is connected to a fixing block 342 for securing the spring 36. Two fixing blocks 342 are provided, one on each side of the spring 36. A positioning post 351 for the spring 36 to engage is provided on the side of the sliding head 35 away from the lifter 12. The fixing blocks 342 cooperate with the positioning posts 351 to effectively secure both ends of the spring 36, facilitating positioning and assembly, and improving assembly efficiency. During use, the spring 36 is fitted onto the positioning posts 351, ensuring that the spring 36 is always pushed toward the sliding head 35, ensuring that the sliding head 35 always abuts the lifter 12.

[0051] Reference Figure 3 、 Figure 4 and Figure 5 A rotating shaft 332 is provided in the middle of the pressure plate 33, and a plurality of clamp arms 42 for clamping the rotating shaft 332 are connected to the bottom of the switch panel 4. The plurality of clamp arms 42 can effectively clamp the rotating shaft 332, thereby achieving a stable connection between the switch panel 4 and the pressure plate 33, ensuring the stability of the connection.

[0052] Reference Figure 4 、 Figure 5 and Figure 6 The two opposite ends of the swing member 32 are connected to rotating blocks 324, and the top ends of the mounting base 31 are connected to rotating bases 312 for the rotating blocks 324 to engage and rotate with. During assembly, the rotating blocks 324 are inserted into the rotating bases 312 and snap-fit together, effectively securing the swing member 32 to the mounting base 31, preventing the swing member 32 from falling out of the mounting base 31, thereby improving assembly accuracy and efficiency.

[0053] Reference Figure 6 The rotating shaft 332 is located directly above the rotating block 324. The distance between the axis of the rotating shaft 332 and the center of the swing rod 34 is greater than the distance between the axis of the rotating block 324 and the center of the swing rod 34. The longer distance between the rotating shaft 332 and the center of the swing rod 34 allows the swing rod 34 at the bottom to rotate at a greater angle when the switch panel 4 rotates, ensuring that the paddle 12 can rotate, thereby achieving circuit closure.

[0054] Reference Figure 3 、 Figure 7 The inner wall of the frame 22 is connected to a fixed shaft 221 for clamping by the clamp arm 42. The axis of the fixed shaft 221 is collinear with the axis of the rotating shaft 332. The fixed shaft 221 effectively positions and secures the switch panel 4 on both sides for rotation. When the switch panel 4 is pressed, the fixed shaft 221 evenly transfers the panel pressure to the frame 22, ensuring uniform force on the switch panel 4 and extending its service life.

[0055] Reference Figure 2 、 Figure 7The inner wall of the groove 11 is connected to a clamping arm 111, and the pressure plate 33 is provided with a clamping groove 333 for the clamping arm 111 to engage. The clamping groove 333 is located on both sides of the rotating shaft 332. This allows the pressure plate 33 to be fixed by both the base 1 and the mounting base 31 at the same time. Even if the connection between the mounting base 31 and the base 1 is unstable, the pressure plate 33 will not fall out of the face frame 2 and cause the switch panel 4 to disassemble, thereby ensuring the stability of the overall structure after assembly.

[0056] The implementation principle of the ultra-thin wall switch of Example 1 of the present application is as follows: during assembly, the mounting seat 31 is installed into the base 1, and then the swinging piece 32 is inserted into the mounting seat 31, the snap arm 311 of the mounting seat 31 can pass through the positioning hole 321 of the swinging piece 32, the rotating blocks 324 at both ends of the swinging piece 32 are snapped and rotated with the rotating seat 312 of the mounting seat 31, and then the pressure plate 33 is covered, the bottom edge of the pressure plate 33 abuts against the reinforcement frame 21, the snap arm 111 of the base 1 is snapped with the snap groove 333 of the pressure plate 33, and the snap arm 311 of the mounting seat 31 is snapped with the snapping part 331 of the pressure plate 33, thereby realizing a stable connection of the pressure plate 33, and finally the switch panel 4 is covered on the surface of the pressure plate 33. This process realizes layered installation, facilitates automated assembly, and improves assembly efficiency.

[0057] Example 2 of the present application discloses an ultra-thin wall switch. The only difference between Example 2 of the present application and Example 1 is that the fixing method of the pressure plate 33 is different.

[0058] Reference Figure 8 The pressing plate 33 is fixedly connected to the frame 22 and is an integrally formed design. Since the pressing plate 33 and the frame 22 are integrally formed, the number of parts of the switch is further reduced, thereby simplifying the assembly process and improving assembly efficiency.

[0059] The implementation principle of the ultra-thin wall switch of Example 2 of the present application is: during assembly, the reinforcement frame 21 is fixedly connected to the base 1, the mounting seat 31 is inserted into the groove 11 of the base 1, and then the swing member 32 is inserted into the mounting seat 31, and the pressure plate 33 is covered. At this time, the frame 22 will be buckled with the reinforcement frame 21, and finally the switch panel 4 is buckled on the surface of the pressure plate 33 to realize assembly. This process facilitates automated assembly and effectively improves assembly efficiency.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
