Description

Technical Field

[0001] This application relates to the field of vehicle parts technology, and in particular to a switch assembly and a side stand switch. Background Technology

[0002] A kickstand is a support structure used on motorcycles or electric vehicles. It is equipped with a side kickstand switch to control the on / off of the circuit. This ensures that the vehicle cannot move even if it is powered on when the kickstand is down, and can only move when the kickstand is retracted, thereby improving the safety of vehicle use.

[0003] The applicant's prior application, Chinese Invention Publication No. CN119480480A, discloses a switch assembly and a side-support switch, which includes a housing, a drive block movably connected inside the housing, a pin fixedly connected inside the housing, an actuating spring fixed on the drive block, a linkage rod movably connected to the housing, a fixed base fixed at one end of the housing, and a mounting base for mounting the fixed base. By triggering the linkage rod to abut against the drive block, the actuating spring abuts against or disengages from the pin to control the circuit on / off. The fixed base is fixed to the mounting base with screws to achieve relative fixation between the fixed base and the housing. This fixing method requires the fixed base and the mounting base to have sufficient thickness, which is inconvenient and wasteful of materials during the production demolding process. In addition, a special screw fixing station is required, making installation inconvenient. Utility Model Content

[0004] To address the inconvenience of installing and securing the mounting base and housing, this application provides a switch assembly and a side-support switch.

[0005] The switching assembly provided in this application adopts the following technical solution:

[0006] A switch assembly includes a housing, pins, a slider, a reset member, and a cover plate. The slider and the reset member are located inside the housing. The pins are fixed to the housing. The housing has a cavity for the slider to slide. The reset member is used to reset the slider. The cover plate is fixed relative to the housing. The assembly further includes: latches on both sides of the cover plate; locking holes for inserting the latches on both sides of the housing; guide surfaces on both sides of the housing; the cover plate is inserted into the housing along the guide surfaces so that the latches are inserted into the locking holes; the rebound force of the reset member drives the slider to abut against the cover plate so that the latches abut against the wall of the locking holes.

[0007] By adopting the above technical solution, the sliding component and the resetting component are located inside the housing. The resetting component is an elastic component with elasticity, used to reset the sliding component after sliding. The cover plate has buckles on both sides, and the housing has matching buckle holes and guide surfaces for guidance. When installing the cover plate, one end of the cover plate is inserted into the housing. When the buckle is inserted into the buckle hole, the cover plate shifts, and the sliding component is compressed by the cover plate. When the cover plate is released after the buckle is inserted into the buckle hole, the restoring force of the resetting component drives the sliding component to move against the cover plate, causing the buckle to press against the hole wall, thereby achieving the snap-fit ​​fixation between the cover plate and the housing. This solves the problems of difficult demolding, material waste, and inconvenient installation caused by screw fixing in the prior art.

[0008] Preferably, the sliding member includes an actuating spring, and the pin includes an integrally connected abutting part and a plugging part. The abutting part is used to abut or disengage from the actuating spring, and the plugging part is used to connect to an external circuit. Fixing plates are fixed on the inner walls of both sides of the housing, and one of the fixing plates has a plugging groove through which the plugging part is inserted. The inner wall of the housing forms one side wall of the plugging groove.

[0009] Preferably, the sliding element further includes a linkage rod for driving the sliding member to slide. The sliding member also includes a fixed block and a limiting block. The fixed block and the limiting block are fixedly connected. The actuating spring is fixed between the fixed block and the limiting block. The linkage rod drives the limiting block and the fixed block to slide, so that the actuating spring abuts against or disengages from the pin. The fixed block includes a first fixing part and a second fixing part fixedly connected. The actuating spring is fixed on the side of the first fixing part facing the limiting block, and the second fixing part is fixed on the other side of the first fixing part. The side of the first fixing part facing the second fixing part is provided with a first mounting groove, and the middle of the second fixing part is provided with a second mounting groove. The second mounting groove and the first mounting groove are connected to each other for mounting the reset member.

[0010] Preferably, the cavity inside the housing for accommodating the sliding member includes a first accommodating groove and a second accommodating groove that are interconnected. The second accommodating groove is located on the side of the first accommodating groove opposite to the linkage rod. The axial projection of the second accommodating groove is located within the axial projection of the first accommodating groove. When the linkage rod drives the sliding member to slide, the first fixing part slides within the first accommodating groove, and the second fixing part slides from the first accommodating groove to the second accommodating groove.

[0011] Preferably, the limiting block has locking arms on both sides, and the locking arm has a locking protrusion at one end away from the limiting block. The fixing block has slots on both sides for the locking arms to engage. The slots include a first slot and a second slot that are connected to each other. The first slot is formed on the first fixing part, and the second slot is formed on the second fixing part. The second fixing part has an abutment protrusion for the locking protrusion to engage, and the abutment protrusion is located in the second slot.

[0012] Preferably, the limiting block has limiting protrusions on both sides, and the outer shell has limiting grooves on both sides along the sliding direction of the limiting block. The limiting protrusions protrude into the limiting grooves, and when the limiting block slides, the limiting protrusions are restricted to sliding within the limiting grooves.

[0013] Preferably, the limiting protrusion is located on the side of the limiting block away from the fixing block. The limiting protrusion includes a connecting part and a limiting part integrally connected. The connecting part is connected to the side of the limiting block away from the fixing block, and the limiting part is connected to the end of the connecting part away from the fixing block. The limiting part protrudes into the limiting groove. When the limiting block slides, the limiting part slides in the limiting groove.

[0014] A side-support switch includes a switch assembly as described above, wherein one end of the plug portion for connection to an external circuit is connected to a lead cable, and a sealing element is fitted onto the connection end of the lead cable and the plug portion, and the sealing element is fixed relative to the housing.

[0015] Preferably, the sealing element is covered with a protective sleeve, and the lead cable passes through one end of the protective sleeve, while the other end of the protective sleeve is snapped onto the outer shell. The inner wall of one end of the sealing element has a first sealing lip, and both the inner and outer walls of the other end of the sealing element have second sealing lips. When the protective sleeve is snapped onto the outer shell, the first sealing lip is in close contact with the lead cable, the second sealing lip located on the outer wall of the sealing element is in close contact with the protective sleeve, and the second sealing lip located on the inner wall of the sealing element is in close contact with the outer shell.

[0035] The following is in conjunction with the appendix Figure 1-14 This application will be described in further detail.

[0036] This application discloses a switching assembly. (Refer to...) Figure 1 and Figure 2 The switch assembly includes a housing 1, pins 2, a slider 3 and a reset member 4 mounted inside the housing 1, a cover plate 5, and a linkage 6. The housing 1 has a cavity for the slider 3 to slide. The pins 2 are fixed to the housing 1. The slider 3 includes an actuating spring 31, which contacts or disengages from the pins 2 to control the on / off state of the circuit. The cover plate 5 is snapped and fixed to one end of the housing 1, allowing the slider 3 to be relatively fixed inside the housing 1. The linkage 6 extends from the outside of the cover plate 5 and abuts against the slider 3. The linkage 6 drives the slider 3 to slide so that the actuating spring 31 contacts or disengages from the pins 2. The reset member 4 is located at the end of the slider 3 furthest from the linkage 6, and the reset member 4 generates elastic force through elastic deformation to reset the slider 3.

[0037] Reference Figure 2 and Figure 3The cover plate 5 has buckles 51 on both sides, and the outer shell 1 has locking holes 11 on both sides for inserting the buckles 51. The buckles 51 can be implemented using injection-molded barb structures, and the locking holes 11 can be implemented using rectangular holes penetrating the side walls. The outer shell 1 has guide surfaces 12 on both sides to guide the cover plate 5 to be accurately inserted. The reset element 4 is a component that can provide elastic restoring force, and the reset element 4 is preferably a spring. When installing the cover plate 5, the cover plate 5 is pushed into the outer shell 1 along the guide surface 12. The buckles 51 on both sides are aligned with the locking holes 11 under the guidance of the guide surface 12, and then the buckles 51 are inserted into the locking holes 11, and the buckles 51 are embedded in the locking holes 11 to form a preliminary positioning. At this time, the reset element 4 is in a compressed state. After the cover plate 5 is released, the elastic force released by the reset element 4 pushes the sliding element 3 to press tightly against the inner surface of the cover plate 5, so that the buckles 51 press tightly against the hole wall of the locking hole 11 to further secure the cover plate 5 and the outer shell 1. Compared to screw connections, the insertion and engagement of the snap-fit ​​51 with the snap-fit ​​hole 11 simplifies the assembly process, and the outer shell 1 and cover plate 5 can adopt a thin-walled design, significantly reducing the difficulty of mold demolding. The linkage design of the reset component 4 and the sliding component 3, in conjunction with the snap-fit ​​51, forms a connection structure with a self-locking function, overcoming the defect of ordinary snap-fits being prone to loosening.

[0038] Reference Figure 1 and Figure 4 Pin 2 includes an integrally connected abutment portion 21 and a plug portion 22. The abutment portion 21 is used to abut or disengage from the actuating spring 31, and the plug portion 22 is plugged into and fixed to the housing 1 for connecting to external circuits. Specifically, fixing plates 13 are fixed on the inner walls of both sides of the housing 1. The sliding member 3 slides on one of the fixing plates 13, and the other fixing plate 13 has a plug groove 131 through which the plug portion 22 is inserted. One end of the plug groove 131 is connected to the outside. The inner wall of the housing 1 forms one side of the plug groove 131. The complete plug groove 131 formed by the inner wall of the housing 1 and the fixing plate 13 can reduce the thickness of the fixing plate 13 to a certain extent and reduce the difficulty of demolding.

[0039] Reference Figure 1 and Figure 5 The sliding member 3 also includes a fixed block 32 and a limiting block 33. The fixed block 32 and the limiting block 33 are fixedly connected. The actuating spring 31 is fixed between the fixed block 32 and the limiting block 33. The connecting rod 6 is located on the side of the limiting block 33 away from the fixed block 32. Driving the connecting rod 6 to slide against the limiting block 33 causes the actuating spring 31 to disengage from the pin 2. The fixed block 32 and the limiting block 33 can be fixedly connected by snap-fit ​​or bolt, so that the actuating spring 31 can be clamped between the fixed block 32 and the limiting block 33 and is less likely to shift.

[0040] Reference Figure 2 and Figure 6The fixing block 32 includes a first fixing part 321 and a second fixing part 322 fixedly connected. The actuating spring 31 is fixed to the side of the first fixing part 321 facing the limiting block 33, and the second fixing part 322 is fixed to the other side of the first fixing part 321. The first fixing part 321 and the second fixing part 322 can be implemented by integral injection molding or by separate assembly. The first fixing part 321 has a first mounting groove 323 on the side facing the second fixing part 322, and the second fixing part 322 has a second mounting groove 324 in the middle. The second mounting groove 324 and the first mounting groove 323 are connected to form a continuous mounting channel, which facilitates the insertion of the reset member 4 along the sliding direction. One end of the reset member 4 located in the second mounting groove 324 and the first mounting groove 323 abuts against the first fixing part 321, and the other end of the reset member 4 abuts against the inner wall of the outer shell 1.

[0041] Reference Figure 5 and Figure 6 The limiting block 33 has locking arms 331 on both sides. The end of each locking arm 331 away from the limiting block 33 has a locking protrusion 332. The fixing block 32 has slots on both sides for the locking arms 331 to engage. These slots include a first slot 325 and a second slot 326 that are connected. The first slot 325 is located on the first fixing part 321, and the second slot 326 is located on the second fixing part 322. Both the first fixing part 321 and the second fixing part 322 have slots to ensure the connection strength between the fixing block 32 and the limiting block 33. Furthermore, the second fixing part 322 has an abutment protrusion 327 for the locking protrusion 332 to engage with. The abutment protrusion 327 is located within the second slot 326. Specifically, the abutment protrusion 327 can be a boss with a shape complementary to the locking protrusion 332 to limit the axial displacement of the locking protrusion 332.

[0042] Reference Figure 2 and Figure 7 The cavity inside the outer casing 1 for accommodating the sliding member 3 includes a first receiving groove 14 and a second receiving groove 15 that are interconnected. The second receiving groove 15 is located on the side of the first receiving groove 14 away from the linkage rod 6. The width of the second receiving groove 15 is smaller than that of the first receiving groove 14 to form a stepped groove. The axial projection of the second receiving groove 15 is located within the axial projection of the first receiving groove 14. The stepped groove design is used to limit the sliding trajectory of the second fixing part 322. When the linkage rod 6 drives the sliding member 3 to slide, the first fixing part 321 slides within the first receiving groove 14, and the second fixing part 322 slides from the first receiving groove 14 to the second receiving groove 15. The step formed by the groove wall of the second receiving groove 15 and the groove wall of the first receiving groove 14 restricts the sliding of the first fixing part 321 towards the second receiving groove 15, thereby limiting the sliding stroke of the second fixing part 322 and the compression stroke of the reset member 4. In addition, the narrowing of the second receiving groove 15 relative to the first receiving groove 14 can reduce the area of ​​the outer casing 1 to a certain extent, thus saving material.

[0043] Reference Figure 6 and Figure 8 The limiting block 33 has limiting protrusions 333 on both sides, and limiting grooves 16 are formed on both sides of the outer shell 1 along the sliding direction of the limiting block 33. When the limiting block 33 slides, the limiting protrusions 333 slide within the limiting grooves 16. The limiting protrusions 333 protrude into the limiting grooves 16, and the width of the limiting grooves 16 maintains a clearance fit with the limiting protrusions 333 to restrict the limiting protrusions 333 to slide linearly only along the length direction of the limiting grooves 16, thus preventing the limiting block 33 from displacing in other directions. The limiting grooves 16 have groove walls at both ends in the length direction, and the sliding trajectory of the limiting block 33 can be limited by setting the length of the limiting grooves 16.

[0044] Furthermore, a limiting protrusion 333 is provided on the side of the limiting block 33 facing away from the fixing block 32. The limiting protrusion 333 includes an integrally connected connecting part 334 and a limiting part 335. The connecting part 334 is connected to the side of the limiting block 33 facing away from the fixing block 32, and the limiting part 335 is connected to the end of the connecting part 334 facing away from the fixing block 32. The limiting part 335 protrudes into the limiting groove 16. Correspondingly, the cover plate 5 is provided with a clearance groove 52 for the connecting part 334 to slide. The limiting groove 16 communicates with the clearance groove 52. When the limiting block 33 slides, the connecting part 334 slides in the clearance groove 52, and the limiting part 335 slides in the limiting groove 16.

[0045] This application also discloses a side-support switch, as shown in the embodiments. Figure 9 and Figure 10 The side support switch includes the switch assembly described above. The plug-in part 22 is connected to an external circuit by a lead cable 7. The lead cable 7 can be a rubber cable with a metal conductor. The connection end of the lead cable 7 and the plug-in part 22 is fitted with a sealing element 8. The sealing element 8 can be made of silicone or rubber material. It forms a tight contact with the outer shell 1 by compression deformation to prevent external medium from entering the connection part 334.

[0046] Reference Figure 11 The seal 8 is covered by a protective sleeve 9, which can be made of elastic rubber or thermoplastic material. The lead cable 7 passes through one end of the protective sleeve 9, and the other end of the protective sleeve 9 is snapped and fixed to the outer shell 1. The axial pressure of the protective sleeve 9 when snapped in fixes the seal 8 between the outer shell 1 and the protective sleeve 9. The protective sleeve 9 covers the outer surface of the seal 8 to form a double-wrap structure, providing mechanical protection for the seal 8 and enhancing the stability of the sealing interface. The exit end of the lead cable 7 is fitted with a tail tube protective cover to further protect the point where the lead cable 7 passes through the protective sleeve 9.

[0047] Reference Figure 12The inner wall of one end of the seal 8 is provided with a first sealing lip 81. The first sealing lip 81 undergoes elastic deformation when squeezed by the lead cable 7, forming a tight fit with the surface of the lead cable 7. The inner and outer walls of the other end of the seal 8 are provided with second sealing lips 82. When the protective sleeve 9 is snapped onto the outer shell 1, the second sealing lip 82 located on the outer wall of the seal 8 is in close contact with the protective sleeve 9, and the second sealing lip 82 located on the inner wall of the seal 8 is in close contact with the outer shell 1. The second sealing lips 82 on both the inner and outer sides of the seal 8 form a double sealing barrier between the protective sleeve 9 and the outer shell 1, preventing liquid or dust from seeping in from the connection between the protective sleeve 9 and the outer shell 1.

[0048] Reference Figure 13 and Figure 14 The outer casing 1 includes a cover 17 and a housing 18. A sealing ring 19 is provided between the cover 17 and the housing 18. The sealing ring 19 is used to seal the connection between the cover 17 and the housing 18.

[0049] The implementation principle of a switch assembly and a side-support switch in this application embodiment is as follows: The cover plate 5 is snapped into the slot 11 by a buckle 51, and the rebound force of the reset member 4 drives the limiting block 33 to abut against the cover plate 5, thereby causing the buckle 51 to press against the inner wall of the slot 11 to fix the cover plate 5 and the outer shell 1. The fixing block 32, the limiting block 33, and the actuating spring 31 are installed in the cavity between two fixing plates 13. The fixing block 32 and the limiting block 33 are relatively fixed by the snap-fit ​​arm 331 snapping into the slot and the snap-fit ​​protrusion 332 abutting against the abutting protrusion 327. The actuating spring 31 is fixed between the fixing block 32 and the limiting block 33. The reset member 4 is installed in the first mounting groove 323 and the second mounting groove 324. One end of the reset member 4 abuts against the inner wall of the outer shell 1, and the other end of the reset member 4 abuts against the groove wall of the first mounting groove 323. The axial projection of the second receiving groove 15 lies within the axial projection of the first receiving groove 14 to form a stepped groove. The stepped groove design restricts the sliding trajectory of the first fixing part 321 and the second fixing part 322. The limiting part 335 slides within the limiting groove 16 to limit the sliding direction and sliding distance of the limiting block 33. The plug-in part 22 connects to the lead cable 7 to transmit electrical signals. The protective sleeve 9 is snapped onto the outer shell 1 so that the first sealing lip 81 fits tightly with the lead cable 7, and the second sealing lip 82 fits tightly with the protective sleeve 9 and the outer shell 1, thereby achieving sealing protection at the connection between the lead cable 7 and the seal 8, as well as at the connection between the seal 8 and the outer shell 1 and the protective sleeve 9.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
