Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more particularly to a switch. Background Technology

[0002] Switches are typically mounted on walls and used to connect and disconnect circuits, controlling lighting equipment. With advancements in switch technology, conventional, thicker switches have gradually been phased out of the market, and ultra-thin switches are increasingly becoming a part of daily life. Therefore, developing ultra-thin switches has become a major focus for switch manufacturers in recent years.

[0003] However, in existing technologies, common two-stage transmission switches can only control the flip angle of the button to about 4°, which results in a switch thickness of about 10mm protruding from the wall, failing to meet the requirements for ultra-thin switches. Utility Model Content

[0004] This application provides a switch that reduces the thickness of the switch protruding from the wall.

[0005] In a first aspect, this application provides a switch comprising a pressure plate, a spring seat, and a button. The pressure plate has a pivot hole. The spring seat includes a front end with a pivot extending into the pivot hole. The button is located on one side of the spring seat and includes a rocker arm and a drive pawl connected to each other. The drive pawl faces the front end and is connected to the spring seat. When the rocker arm is driven to swing, the drive pawl causes the spring seat to swing. When the spring seat swings, the pivot can rotate within the pivot hole. The pivot hole provides dual-point limiting for the pivot.

[0006] The above scheme provides the necessary mounting conditions for the spring seat by setting up the pressure plate. Once the shaft is inserted into the shaft hole, the spring seat can swing using the pressure plate as its base. By setting a button, when force is applied to the rocker to make it swing, the drive pawl can drive the spring seat to swing synchronously. When the shaft hole provides double-point limiting for the shaft, the angle of shaft rotation can be reduced. As the angle of shaft rotation decreases, the swing angle of the spring seat also decreases. Since the rocker and spring seat swing synchronously, and the drive pawl is connected to the spring seat, the rocker's swing angle can be reduced. As the rocker's swing angle decreases, the height of the rocker protruding from the external mounting surface decreases, thus reducing the switch's wall thickness and achieving an ultra-thin switch design.

[0007] In one possible design, the pivot hole includes a first limiting part and a second limiting part, and the pivot includes a first abutting part and a second abutting part. During the process of the seesaw being driven to swing in a first direction, the first abutting part can abut against the first limiting part, and the second abutting part can abut against the second limiting part to limit the seesaw from continuing to swing in the first direction.

[0008] With the above scheme, during the process of the seesaw being driven to swing in the first direction, the first abutting part abuts against the first limiting part, so that the pivot hole can limit the pivot at the first point, and the second abutting part abuts against the second limiting part, so that the pivot hole can limit the pivot at the second point. In this way, during the process of the seesaw being driven to swing in the first direction, the pivot hole can limit the pivot at two points.

[0009] In one possible design, the pivot hole includes a third limiting part and a fourth limiting part, and the pivot includes a third abutting part and a fourth abutting part. During the process of the seesaw swinging in a second direction, the third abutting part abuts against the third limiting part, and the fourth abutting part abuts against the fourth limiting part, to limit the seesaw from continuing to swing in the second direction, which is opposite to the first direction.

[0010] With the above scheme, during the process of the seesaw being driven to swing in the second direction, the third abutting part abuts against the third limiting part, so that the pivot hole can limit the pivot at the first point, and the fourth abutting part abuts against the fourth limiting part, so that the pivot hole can limit the pivot at the second point. In this way, during the process of the seesaw being driven to swing in the second direction, the pivot hole can limit the pivot at two points.

[0011] In one possible design, the pivot hole is an elliptical hole, and the pivot is an elliptical cylinder. Alternatively, the pivot hole is an oblong hole, and the pivot is an oblong cylinder.

[0012] With the above scheme, both the rotating shaft and the rotating shaft hole have a certain curvature, which can achieve dual-point limiting of the rotating shaft by the rotating shaft hole without affecting the rotation of the rotating shaft within the rotating shaft hole.

[0013] In one possible design, the spring seat also includes a drive plate located at the front end. A boss is provided on the front-facing side of the rocker, which abuts against the drive plate.

[0014] The above solution involves setting a drive plate at the front end of the spring seat and a boss at the front end of the rocker. After the switch is assembled, the boss can abut against the drive plate. When the rocker swings, the boss can apply force to the drive plate, causing the drive plate to drive the spring seat to swing synchronously with the rocker. This reduces the probability of the rocker swinging but the spring seat not swinging, thus reducing the probability of switch failure.

[0015] In one possible design, the spring seat also includes an abutment block located on the side of the spring seat facing away from the rocker. The drive plate has a through slot through which the drive pawl passes and abuts against the abutment block.

[0016] By using the above solution, a through slot is provided on the drive plate to allow room for the drive claw, enabling it to abut against the abutment block. By placing the abutment block on the spring seat, allowing the drive claw to abut against the block, the probability of the rocker not being able to immediately swing the spring seat during its swing due to a gap between the drive claw and the spring seat is reduced, thus decreasing the probability of switch failure.

[0017] In one possible design, the abutment block includes a first abutment block and a second abutment block, which are symmetrically arranged about the central axis of the spring seat. The drive pawl includes a first pawl and a second pawl, with a gap between them, and is also symmetrically arranged about the central axis of the spring seat. The first pawl abuts against the first abutment block, and the second pawl abuts against the second abutment block.

[0018] With the above solution, a first abutting block and a second abutting block are set on the spring seat, and the driving claw is set in the form of a combination of the first claw and the second claw. When the driving claw is connected to the spring seat, the first claw and the second claw can clamp the spring seat by abutting the first abutting block and the second abutting block. In this way, whether the rocker swings clockwise or counterclockwise, the driving claw can drive the spring seat to swing immediately, reducing the probability of switch failure.

[0019] In one possible design, the switch also includes a rear seat containing a conductive component for connection to an external power source. Both the pressure plate and the spring seat are located within the rear seat. The spring seat includes a rear end, which is connected to the conductive component via a connector.

[0020] With the above solution, the rear seat can provide installation space for the conductive components, pressure plate and spring seat. When the spring seat is connected to the conductive components through the connector, the swing of the spring seat can be used to control the on and off of the conductive components, thereby realizing the basic function of a switch.

[0021] In one possible design, the switch also includes a mounting bracket that is fitted onto the rear seat. The mounting bracket has reinforcing ribs. The mounting bracket is secured to the external mounting surface by fasteners.

[0022] The above solution allows the mounting bracket to be used to fix the rear seat to an external mounting surface. The reinforcing ribs increase the strength of the mounting bracket. By adding reinforcing ribs, the probability of the mounting bracket denting towards the rear seat under external force during switch use can be reduced. This reduces the likelihood of connection failure between the drive claw and the spring seat after the mounting bracket dents, thus improving the reliability of the switch.

[0023] In one possible design, the switch also includes a panel disposed between the rocker and the mounting bracket. The panel is mounted on the mounting bracket, with the side of the panel away from the rocker abutting against an external mounting surface. A fixed shaft is provided on the side of the panel near the rocker, and an arc-shaped groove is provided on the side of the rocker facing the panel. The arc-shaped groove engages with the fixed shaft, allowing the rocker to swing around the fixed shaft.

[0024] The above design not only provides a mounting base for the buttons but also protects the backrest. When the panel is mounted on the mounting bracket, the side of the panel furthest from the rocker abuts against the external mounting surface, thus reducing the switch's thickness. The cooperation between the fixed shaft and the arc-shaped groove allows the rocker to swing under external force. Attached Figure Description

[0052] 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.

[0053] A switch is typically mounted on a wall and used to connect and disconnect circuits to control lighting equipment. A switch usually consists of a drive assembly and a conductive assembly connected together. The drive assembly typically includes a button, a spring seat, and a pressure plate. The conductive assembly typically includes a moving contact and a stationary contact. The drive assembly and the conductive assembly are connected through the cooperation of the spring seat and the moving contact. After the drive assembly and the conductive assembly are connected, when the button is pressed, the button can directly or indirectly drive the spring seat to swing around the pressure plate. When the spring seat rotates, it can cause the moving contact to contact the stationary contact, thus connecting the circuit; or it can cause the moving contact to separate from the stationary contact, thus disconnecting the circuit.

[0054] With the development of switch technology, conventional, thicker switches have gradually been phased out of the market, and ultra-thin switches have gradually entered people's lives. Furthermore, switches are generally installed on external surfaces, such as walls. Thicker switches not only affect aesthetics but also increase the risk of bumps and knocks. Therefore, developing ultra-thin switches has become a major focus for switch manufacturers in recent years.

[0055] To achieve ultra-thin switches, those skilled in the art typically improve the drive assembly. For example, the drive assembly can be configured as an interconnected button, spring seat, and pressure plate, with the spring seat mounted on the pressure plate. When the button is connected to the spring seat, a two-stage transmission relationship can be formed between them. Based on this two-stage transmission relationship, when the rotation angle of the spring seat relative to the pressure plate decreases, the angle that the button needs to rotate can also be reduced. In this way, the thickness of the switch can also be reduced.

[0056] Based on this, this application provides a switch that reduces the thickness of the switch protruding from the wall by changing the rotation angle of the spring seat relative to the pressure plate.

[0057] Figure 1 This is a schematic diagram of the structure of the pressure plate provided in an embodiment of this application. Figure 2 This is a schematic diagram of the spring seat provided in an embodiment of this application from a first-view perspective. Figure 3 This is a schematic diagram of the button structure provided in an embodiment of this application. Figures 1 to 3As shown, this application provides a switch, which includes a pressure plate 100, a spring seat 200, and a button 300. The pressure plate 100 has a pivot hole 110. The spring seat 200 includes a front end 210, and the front end 210 has a pivot 211, which extends into the pivot hole 110. The button 300 is located on one side of the spring seat 200, and the button 300 includes a rocker arm 310 and a drive pawl 320 connected to each other. The drive pawl 320 is positioned towards the front end 210 and is connected to the spring seat 200. When the rocker arm 310 is driven to swing, the drive pawl 320 causes the spring seat 200 to swing. When the spring seat 200 swings, the pivot 211 can rotate within the pivot hole 110. The pivot hole 110 can provide dual-point limiting for the pivot 211.

[0058] The pressure plate 100 is a component for mounting the spring seat 200. When the spring seat 200 is mounted on the pressure plate 100, the pressure plate 100 can be fixedly set and the pivot 211 of the front end 210 of the spring seat 200 can be received through the pivot hole 110 so that the spring seat 200 is mounted on the pressure plate 100.

[0059] A clearance groove can be provided on the pressure plate 100 so that the spring seat 200 can pass through the pressure plate 100. Since the button 300 and the conductive component 500 are respectively provided on both sides of the pressure plate 100, the spring seat 200 can pass through the pressure plate 100 so that the button 300 and the conductive component 500 can be connected at the same time after the spring seat 200 is installed on the pressure plate 100.

[0060] The pivot hole 110 can be a hole-like structure near the clearance groove on the pressure plate 100, and there can be two pivot holes 110. The pivot hole 110 can be a through hole.

[0061] The spring seat 200 can swing under force. When the spring seat 200 swings, it can cause the moving contact component of the switch to contact or separate from the stationary contact component. A pivot 211 can be provided on each of the two opposite side walls of the spring seat 200. Both pivots 211 can be protrusions on the side walls of the spring seat 200. The two pivots 211 can be symmetrically arranged, thus making the spring seat 200 more stable when swinging.

[0062] Figure 4 An exploded view of a switch provided in an embodiment of this application. Figure 2 as well as Figure 4As shown, the spring seat 200 may include a front end 210 and a rear end 240, which are positioned opposite each other. When the rotating shaft 211 is located at the front end 210, the rear end 240 can be connected to the conductive component 500. Furthermore, when the rotating shaft 211 is located at the front end 210, the spring seat 200 can increase the swing amplitude of the rear end 240 during its swinging process, thereby improving the reliability of the contact or separation between the moving contact component and the stationary contact component in the conductive component 500.

[0063] The button 300 can be a component that applies force to the spring seat 200, causing the spring seat 200 to swing. The drive pawl 320 can be a protrusion structure provided on the rocker 310 facing the front end 210 of the spring seat 200. The drive pawl 320 can be connected to the spring seat 200, so that when the rocker 310 is subjected to an external force and swings, the drive pawl 320 can drive the spring seat 200 to swing.

[0064] Since the pressure plate 100 is fixedly installed, the rotating shaft 211 extends into the rotating shaft hole 110. Therefore, when the spring seat 200 swings, the rotating shaft 211 can rotate within the rotating shaft hole 110. When the rotating shaft 211 rotates within the rotating shaft hole 110 until it can no longer rotate, the hole wall of the rotating shaft hole 110 and the side wall of the rotating shaft 211 abut at two points. At this time, the rotating shaft hole 110 limits the rotating shaft 211 at two points.

[0065] Dual-point limiting refers to the fact that when the rotating shaft 211 swings within the rotating shaft hole 110 to the point where it can no longer swing, the rotating shaft hole 110 can limit the rotating shaft 211 at two points.

[0066] In summary, the pressure plate 100 provides the necessary conditions for installing the spring seat 200. When the rotating shaft 211 extends into the rotating shaft hole 110, the spring seat 200 can swing relative to the pressure plate 100 base. By setting the button 300, when force is applied to the rocker 310 to cause it to swing, the drive pawl 320 can drive the spring seat 200 to swing synchronously.

[0067] Figure 5 This is a schematic diagram of the switch provided in an embodiment of this application from one viewpoint. Figure 6 An explanatory diagram of a two-point limiting device provided in an embodiment of this application. (See diagram below.) Figure 1 , Figure 2 , Figure 5 as well as Figure 6As shown, when the pivot hole 110 provides double-point limiting for the pivot 211, the rotation angle of the pivot 211 can be reduced. When the rotation angle of the pivot 211 decreases, the swing angle of the spring seat 200 also decreases. Since the rocker arm 310 swings synchronously with the spring seat 200, and the drive pawl 320 is connected to the spring seat 200, the swing angle of the rocker arm 310 can be reduced. When the swing angle of the rocker arm 310 decreases, the height of the rocker arm 310 protruding from the external mounting surface decreases. At this point, the wall thickness 'a' of the switch decreases, thus achieving an ultra-thin switch design.

[0068] To facilitate understanding of the dual-point limit, the following detailed explanation is provided in conjunction with the illustrations and embodiments.

[0069] like Figure 1 , Figure 2 as well as Figure 6 As shown, the pivot hole 110 includes a first limiting part and a second limiting part, and the pivot 211 includes a first abutting part and a second abutting part. During the process of the seesaw 310 being driven to swing in the first direction, the first abutting part can abut against the first limiting part, and the second abutting part can abut against the second limiting part to limit the seesaw 310 from continuing to swing in the first direction.

[0070] Figure 6 The two points marked in the middle can be the two limiting points between the rotating shaft hole 110 and the rotating shaft 211.

[0071] The first limiting part can be a part on the wall of the rotating shaft hole 110, and the second limiting part can also be a part on the wall of the rotating shaft hole 110. Furthermore, the first limiting part and the second limiting part are not on the same side, so that when the rotating shaft 211 rotates, the rotating shaft hole 110 can limit the rotating shaft 211 at two points.

[0072] The first abutment can be a part on the side wall of the rotating shaft 211, and the second abutment can also be a part on the side wall of the rotating shaft 211. Furthermore, the first abutment and the second abutment are not on the same side.

[0073] The first direction can be clockwise. When the rocker arm 310 is driven by an external force to swing clockwise, the drive pawl 320 can drive the spring seat 200 to swing clockwise. When the rotating shaft 211 rotates in the rotating shaft hole 110 until it can no longer rotate, the first abutting part abuts against the first limiting part, and the second abutting part abuts against the second limiting part. At this time, the spring seat 200 can no longer swing clockwise, and at the same time, the rocker arm 310 can no longer swing clockwise.

[0074] With the above configuration, during the process of the rocker 310 being driven to swing in the first direction, the first abutting part abuts against the first limiting part, so that the pivot hole 110 can limit the pivot 211 at the first point, and the second abutting part abuts against the second limiting part, so that the pivot hole 110 can limit the pivot 211 at the second point. In this way, during the process of the rocker 310 being driven to swing in the first direction, the pivot hole 110 can limit the pivot 211 at two points.

[0075] Please continue to refer to Figure 1 , Figure 2 as well as Figure 6 As shown, the pivot hole 110 includes a third limiting part and a fourth limiting part, and the pivot 211 includes a third abutting part and a fourth abutting part. During the process of the seesaw 310 being driven to swing in the second direction, the third abutting part can abut against the third limiting part, and the fourth abutting part can abut against the fourth limiting part to limit the seesaw 310 from continuing to swing in the second direction, which is opposite to the first direction.

[0076] The third limiting part can be a part on the wall of the rotating shaft hole 110, and the fourth limiting part can also be a part on the wall of the rotating shaft hole 110. Furthermore, the third limiting part and the fourth limiting part are not on the same side, so that when the rotating shaft 211 rotates, the rotating shaft hole 110 can perform double-point limiting on the rotating shaft 211.

[0077] The third abutment can be a part on the side wall of the rotating shaft 211, and the fourth abutment can also be a part on the side wall of the rotating shaft 211. Furthermore, the third abutment and the fourth abutment are not on the same side.

[0078] The second direction is opposite to the first direction, and the second direction can be counterclockwise. The rocker 310 swinging in the first direction and the rocker 310 swinging in the second direction can control two states of the switch respectively. For example, when the rocker 310 swings in the first direction, the switch can switch from an open state to a closed state; when the rocker 310 swings in the second direction, the switch can switch from a closed state to an open state.

[0079] When the rocker arm 310 is driven by an external force to swing clockwise, the drive pawl 320 can drive the spring seat 200 to swing clockwise. When the rotating shaft 211 rotates within the rotating shaft hole 110 until it can no longer rotate, the third abutting part abuts against the third limiting part, and the fourth abutting part abuts against the fourth limiting part. At this time, the spring seat 200 can no longer swing counterclockwise, and at the same time, the rocker arm 310 can no longer swing counterclockwise.

[0080] With the above configuration, during the process of the seesaw 310 being driven to swing in the second direction, the third abutting part abuts against the third limiting part, so that the pivot hole 110 can limit the pivot 211 at the first point, and the fourth abutting part abuts against the fourth limiting part, so that the pivot hole 110 can limit the pivot 211 at the second point. In this way, during the process of the seesaw 310 being driven to swing in the second direction, the pivot hole 110 can limit the pivot 211 at two points.

[0081] Based on the above description, this application provides examples of the rocker 310 swinging clockwise and counterclockwise. During the swinging of the rocker 310 clockwise or counterclockwise, not only can the spring seat 200 connect or disconnect the conductive component 500, but the switch provided in this application can also utilize the pivot hole 110 on the pressure plate 100 to provide dual-point limiting for the pivot 211 on the spring seat 200. Thus, it can be demonstrated that the switch mentioned in this application can achieve ultra-thinness in both the open and closed states.

[0082] Since the rotating shaft 211 needs to rotate within the rotating shaft hole 110, and the rotating shaft hole 110 also needs to limit the rotating shaft 211 at two points, this application has made improvements to both the rotating shaft 211 and the rotating shaft hole 110. The improvements in the embodiments of this application will be specifically described below with reference to the accompanying drawings, but this does not constitute a limitation on the solution of this application.

[0083] Figure 7 This is a schematic diagram of the spring seat 200 provided in an embodiment of this application from a second perspective. Figure 1 , Figure 2 as well as Figure 7 As shown, the pivot hole 110 can be an elliptical hole, and the pivot 211 can be an elliptical cylinder. Alternatively, the pivot hole 110 can be an oblong hole, and the pivot 211 can be an oblong cylinder.

[0084] When the pivot hole 110 is an elliptical hole, the aforementioned first limiting part, second limiting part, third limiting part, and fourth limiting part can all be provided on the hole wall with a smaller curvature inside the elliptical hole. When the pivot 211 is an elliptical cylinder, the cross section of the pivot 211 perpendicular to the axis direction can be elliptical, and the first abutting part, second abutting part, third abutting part, and fourth abutting part can all be provided on the side wall with a smaller curvature on the elliptical cylinder.

[0085] When the pivot hole 110 is an oblong hole, the aforementioned first limiting part, second limiting part, third limiting part, and fourth limiting part can all be provided on two parallel hole walls of the oblong hole. When the pivot 211 is an oblong column, the cross-section of the pivot 211 perpendicular to the axial direction can be oblong, and the first abutting part, second abutting part, third abutting part, and fourth abutting part can all be provided on two parallel side walls of the oblong column.

[0086] With the above settings, both the rotating shaft 211 and the rotating shaft hole 110 have a certain curvature, which can achieve dual-point limiting of the rotating shaft 211 by the rotating shaft hole 110 without affecting the rotation of the rotating shaft 211 within the rotating shaft hole 110.

[0087] Because the rotating shaft 211 is double-limited by the rotating shaft hole 110, the angle of rotation of the rotating shaft 211 within the rotating shaft hole 110 becomes smaller. This results in a smaller swing angle between the spring seat 200 and the rocker 310. When the swing angle between the spring seat 200 and the rocker 310 becomes smaller, the driving pawl 320 may not be able to drive the spring seat 200 to swing in time during the swing of the rocker 310, thus causing the switch to malfunction. Based on this, the following improvements have been made in this application.

[0088] Figure 7 This is a schematic diagram of the spring seat 200 provided in an embodiment of this application from a second perspective. Figure 2 , Figure 3 as well as Figure 7 As shown, the spring seat 200 also includes a drive plate 220, which is disposed at the front end 210. The rocker 310 has a boss 312 on the side facing the front end 210, and the boss 312 abuts against the drive plate 220.

[0089] The drive plate 220 can be a plate-like structure. Since the front end 210 faces the rocker 310, and the drive plate 220 needs to cooperate with the rocker 310, the drive plate 220 can be located at the front end 210. The boss 312 can be a protrusion structure of the rocker 310 facing the front end 210, and the boss 312 can be located on the same side as the drive claw 320.

[0090] There can be two bosses 312, which can be respectively set on the rocker 310 at positions corresponding to both ends of the drive plate 220. In this way, whether the rocker 310 rotates clockwise or counterclockwise, the bosses 312 can apply force to the rocker 310.

[0091] In summary, a drive plate 220 is provided at the front end 210 of the spring seat 200, and a boss 312 is provided on the rocker 310 facing the front end 210. After the switch is assembled, the boss 312 can abut against the drive plate 220. In this way, when the rocker 310 swings, the boss 312 can apply force to the drive plate 220, causing the drive plate 220 to drive the spring seat 200 to swing synchronously with the rocker 310. This reduces the probability of the rocker 310 swinging while the spring seat 200 does not swing, thus reducing the probability of switch failure.

[0092] Figure 8 This is a schematic diagram of the spring seat 200 provided in an embodiment of this application from a third-person perspective. Further, as... Figure 3 as well as Figure 8 As shown, the spring seat 200 also includes an abutment block 230, which is disposed on the side of the spring seat 200 facing away from the rocker plate 310. The drive plate 220 is provided with a through groove 221, through which the drive claw 320 passes and abuts against the abutment block 230.

[0093] The abutment block 230 can be a protrusion on the spring seat 200, and can be located on the side of the drive plate 220 facing away from the rocker arm 310. The abutment block 230 can also be located on the side wall of the spring seat 200. Since the drive plate 220 is located at the front end 210, it can have a through groove 221 along the mounting direction of the spring seat 200, allowing the drive claw 320 to pass through the through groove 221 and abut against the abutment block 230.

[0094] With the above configuration, the through slot 221 on the drive plate 220 allows space for the drive claw 320, enabling it to abut against the abutment block 230. The abutment block 230 on the spring seat 200, allowing the drive claw 320 to abut against it, reduces the probability of the rocker 310 failing to immediately drive the spring seat 200 during its swing due to a gap between the drive claw 320 and the spring seat 200, thus reducing the probability of switch failure.

[0095] Further, please continue to refer to Figure 3 as well as Figure 8 As shown, the abutment block 230 includes a first abutment block 231 and a second abutment block 232, which are symmetrically arranged about the central axis of the spring seat 200. The drive claw 320 includes a first claw 321 and a second claw 322, with a gap between them. The first claw 321 and the second claw 322 are symmetrically arranged about the central axis of the spring seat 200. The first claw 321 abuts against the first abutment block 231, and the second claw 322 abuts against the second abutment block 232.

[0096] The first abutment block 231 and the second abutment block 232 can be disposed on two opposite sidewalls of the spring seat 200. The distance between the first claw 321 and the second claw 322 can be equal to the farthest distance between the first abutment block 231 and the second abutment block 232. This farthest distance is the maximum distance between the side of the first abutment block 231 facing away from the second abutment block 232 and the side of the second abutment block 232 facing away from the first abutment block 231.

[0097] With the above configuration, a first abutment block 231 and a second abutment block 232 are provided on the spring seat 200, and the driving claw 320 is configured as a combination of the first claw 321 and the second claw 322. When the driving claw 320 is connected to the spring seat 200, the first claw 321 and the second claw 322 can clamp the spring seat 200 by abutting against the first abutment block 231 and the second abutment block 232. In this way, whether the rocker 310 swings clockwise or counterclockwise, the driving claw 320 can drive the spring seat 200 to swing immediately, reducing the probability of switch failure.

[0098] like Figure 2 , Figure 4 as well as Figure 7 As shown, the switch also includes a rear seat 400, within which a conductive component 500 is provided for connection to an external power source. The pressure plate 100 and the spring seat 200 are both located within the rear seat 400. The spring seat 200 includes a rear end 240, which is connected to the conductive component 500 via a connector.

[0099] The rear seat 400 can be located on the side of the spring seat 200 away from the button 300. The rear seat 400 has an installation space inside, and the conductive component 500, the pressure plate 100 and the spring seat 200 can all be installed in this installation space. The pressure plate 100 can be fixedly connected to the rear seat 400, so that the spring seat 200 will be more stable during the swinging process.

[0100] The conductive component 500 typically includes a moving contact component and a stationary contact component. The moving contact component is connected to the spring seat 200, which can drive the moving contact component to swing during the swinging process. The stationary contact component is fixedly installed inside the rear seat 400 and is connected to an external wire.

[0101] The rear end 240 of the spring seat 200 is positioned opposite the front end 210 of the spring seat 200, and the abutment block 230 can be disposed between the front end 210 and the rear end 240. The rear end 240 may be provided with a mounting hole, and the spring seat 200 can be connected to the moving contact member by a spring. One end of the spring can be inserted into the mounting hole of the rear end 240, and the other end of the spring can be fixedly connected to the moving contact member.

[0102] With the above configuration, the rear seat 400 can provide installation space for the conductive component 500, the pressure plate 100 and the spring seat 200. When the spring seat 200 is connected to the conductive component 500 through the connector, the swing of the spring seat 200 can be used to control the on / off state of the conductive component 500, thereby realizing the basic function of a switch.

[0103] Figure 9 This is a structural schematic diagram of the mounting bracket 600 provided in an embodiment of this application. Figure 4 as well as Figure 9 As shown, the switch also includes a mounting bracket 600, which is fitted onto the rear seat 400. The mounting bracket 600 is provided with reinforcing ribs 610. The mounting bracket 600 is fixed to the external mounting surface by fasteners.

[0104] The mounting bracket 600 can be a U-shaped structure. A reinforcing rib 610 can be provided on the side of the mounting bracket 600 facing the button 300, and another reinforcing rib 610 can be provided on the side of the mounting bracket 600 facing the rear seat 400. The mounting bracket 600 can be made of high-strength cold-rolled steel strip.

[0105] The mounting bracket 600 is fixedly connected to the rear seat 400. The mounting bracket 600 is provided with mounting holes. The mounting bracket 600 can be fixed to the external mounting surface by fasteners. At this time, the rear seat 400 is located inside the external mounting surface.

[0106] Stiffener 610 is a commonly used reinforcing material in structural design, typically used to increase the strength and rigidity of a structure. During structural design, if the overhang of a structure is too large or the span is too large, the load-bearing capacity of the connection surfaces of the structural components is limited. In this case, a reinforcing plate, commonly known as stiffener 610, can be added to the common vertical surface of the two connected components. This application uses stiffener 610 on the mounting frame 600 to improve the strength of the mounting frame 600.

[0107] In summary, the mounting bracket 600 can be used to fix the rear seat 400 to an external mounting surface. The reinforcing rib 610 can improve the strength of the mounting bracket 600. By setting the reinforcing rib 610, the probability of the mounting bracket 600 denting towards the rear seat 400 under external force during use can be reduced. This reduces the probability of the drive claw 320 failing to connect with the spring seat 200 after the mounting bracket 600 dents, thus improving the reliability of the switch.

[0108] Figure 10 This is a schematic diagram of the structure of panel 700 provided in an embodiment of this application. Figure 3 , Figure 4 as well as Figure 10As shown, the switch also includes a panel 700, which is disposed between the rocker arm 310 and the mounting bracket 600. The panel 700 covers the mounting bracket 600, and the side of the panel 700 away from the rocker arm 310 abuts against the external mounting surface. A fixed shaft 710 is provided on the side of the panel 700 near the rocker arm 310, and an arc-shaped groove 311 is provided on the side of the rocker arm 310 facing the panel 700. The arc-shaped groove 311 engages with the fixed shaft 710, allowing the rocker arm 310 to swing around the fixed shaft 710.

[0109] The panel 700 can be positioned between the rocker arm 310 and the mounting bracket 600. The panel 700 has a mounting space facing the mounting bracket 600. When the panel 700 is placed on the mounting bracket 600, the side of the panel 700 facing the mounting bracket 600 abuts against the external mounting surface. The panel 700 can provide a mounting base for the button 300.

[0110] The fixed shaft 710 can be a columnar structure provided on the side of the panel 700 facing the rocker 310. The arc-shaped slot 311 can be a groove structure provided on the side of the rocker 310 facing the panel 700. The arc-shaped slot 311 can match the fixed shaft 710. When the arc-shaped slot 311 is engaged with the fixed shaft 710, the rocker 310 can swing around the fixed shaft 710.

[0111] In summary, the panel 700 not only provides a mounting base for the button 300, but also provides protection for the rear seat 400. When the panel 700 is mounted on the mounting bracket 600, the side of the panel 700 away from the rocker 310 abuts against the external mounting surface, thus reducing the thickness of the switch. The cooperation between the fixed shaft 710 and the arc-shaped slot 311 allows the rocker 310 to swing under external force.
