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 pin and a slider, and further includes a first housing and a second housing. A sliding cavity is formed in the first housing, and the slider is slidably disposed in the sliding cavity. The pin is fixedly disposed on the first housing. An opening is formed in the sliding cavity on the side of the slider away from the pin. The opening is covered by the second housing. A snap fastener is provided on the outside of the second housing. The first housing and the second housing are fixedly connected by the snap fastener.

[0007] By adopting the above technical solution, the first housing provides a precise sliding track for the sliding component through its internal sliding cavity. Pins are fixed to the first housing to form circuit contacts, and the movement of the sliding component controls the on / off state of the contacts. The second housing directly snaps into the opening side of the first housing via a snap-fit, forming a complete closed cavity. During assembly, the second housing is pressed in a predetermined direction, and the snap-fit, after elastic deformation, locks into the first housing. This solution replaces screw fixing with snap-fit ​​connection, eliminating the need for machining screw mounting holes, reducing the thickness requirements of the housing components, making injection molding easier for demolding and saving materials. The assembly process requires no special tools or screw tightening steps, and the direct snap-fit ​​operation saves time compared to screw tightening, significantly improving assembly efficiency.

[0008] Preferably, it also includes a cover, which covers the outer side of the first housing away from the second housing, one end of the pin protrudes from the cover, and the other end of the pin is covered by the cover.

[0009] Preferably, the outer surface of the first housing is provided with a limiting block, and the housing cover is provided with a limiting groove. One end of the pin and the limiting block pass through the limiting groove, and the limiting block abuts against the pin and is relatively confined within the limiting groove.

[0010] Preferably, the sliding cavity has an abutment protrusion on the side wall facing the opening of the sliding cavity for the pin to abut against.

[0011] Preferably, the outer side of the first housing is provided with two limiting protrusions spaced apart. The limiting protrusions are provided with guide slopes along the insertion direction of the buckle. The buckle includes a buckle arm and a buckle hook. The buckle hook is located at the end of the buckle arm away from the second housing. The buckle hook is located on both sides of the buckle arm. The end face of the limiting protrusion away from the second housing abuts against the side of the buckle facing the second housing to restrict the buckle from falling out in the opposite direction.

[0012] Preferably, it further includes a reset member, wherein the second housing protrudes away from the first housing to form a receiving cavity for accommodating the reset member, one end of the reset member abuts against the sliding member, and the other end of the reset member abuts against the bottom wall of the receiving cavity.

[0013] Preferably, it further includes a linkage rod, one end of which passes through the first housing and the end away from the second housing to abut against the sliding member, and a sealing member is provided on the side of the cover away from the second housing, the sealing member being used to seal the connection between the linkage rod and the cover.

[0014] A side-support switch includes a switch assembly as described above, and a housing. One end of the housing has a mounting cavity for mounting the switch assembly. The second housing has a snap-fit ​​protrusion, and the cavity wall of the mounting cavity has a slot for the snap-fit ​​protrusion to engage.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] Injection molding is easier to demold and saves materials. The snap-fit ​​connection structure reduces the thickness requirements of the shell parts, and the shell wall thickness can be appropriately reduced. There is no need to set the mold core pulling mechanism corresponding to the screw hole position during injection molding, which simplifies the mold structure.

[0017] Easy to install, high production and assembly efficiency. The design of the first housing, second housing and cover optimizes the overall housing structure and assembly space of the switch assembly. The housing structure is simpler and more compact, reducing production complexity. Each component can be assembled through simple snap-fit ​​and press operations.

[0018] The sealing is simple and effective. The shells can be fitted together without the need for additional seals, which simplifies the sealing design and improves the sealing effect. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0027] This application discloses a switching assembly. (Refer to...) Figure 1 and Figure 2 The switch assembly includes an outer casing 1, a pin 2, a connecting rod 3, a slider 4 mounted inside the outer casing 1, and a reset member 5. The outer casing 1 has a sliding cavity 11, and the slider 4 is slidably disposed within the sliding cavity 11. The pin 2 is fixed to the outer casing 1, and one end of the pin 2 extends from inside the outer casing 1 to connect to an external circuit. (See attached diagram.) Figure 3 The sliding member 4 includes an actuating spring 41 and a fixing seat 42 for fixing the actuating spring 41. The actuating spring 41 abuts or disengages from the pin 2 to control the circuit's on / off state. The linkage 3 is movably connected to the outer casing 1 to drive the sliding member 4 to slide so that the actuating spring 41 abuts or disengages from the pin 2. The reset member 5 is located at the end of the sliding member 4 away from the linkage 3. The reset member 5 generates elastic force through elastic deformation to reset the sliding member 4.

[0028] Reference Figure 2 and Figure 3The outer shell 1 includes a first shell 12 and a second shell 13. Pins 2 are fixed to the first shell 12. A sliding cavity 11 is located inside the first shell 12, with an opening on the side of the slider 4 away from the pins 2. The slider 4 is installed inside the first shell 12 through the opening of the sliding cavity 11. One end of the linkage rod 3 passes through the first shell 12, while the end away from the second shell 13 extends into the sliding cavity 11 to abut against the slider 4. A buckle 131 is located on the outer side of the second shell 13. The second shell 13 is detachably connected to the first shell 12 via the buckle 131 and covers the opening of the sliding cavity 11, forming a relatively closed cavity between the first shell 12 and the second shell 13. During assembly, the second shell 13 is pressed together in a predetermined direction, and the buckle 131, after elastic deformation, locks with the first shell 12. The buckle 131 connection structure reduces the thickness requirements of the shell components, making demolding easier during injection molding, saving materials, and simplifying the assembly process. Meanwhile, the opening of the sliding cavity 11 is completely covered by the second housing 13, which not only ensures the movement space of the sliding member 4, but also forms a relatively closed area to prevent foreign objects from entering.

[0029] Reference Figure 1 and Figure 3 In one embodiment, a limiting protrusion 121 extends from the outer surface of the first housing 12. Two limiting protrusions 121 are spaced apart on the outer side of the first housing 12. A guide slope 122 is provided on the limiting protrusion 121 along the insertion direction of the latch 131. Specifically, the limiting protrusion 121 can be implemented using a trapezoidal block structure. The latch 131 includes a latch arm 132 and a latch hook 133. The latch arm 132 is a straight rod-shaped structure extending from the second housing 13 toward the direction close to the first housing 12. The width of the latch arm 132 matches the distance between the two limiting protrusions 121 and is used to transmit locking force. The latch hook 133 is located at the end of the latch arm 132 away from the second housing 13. It is a protruding structure formed by the end of the latch arm 132 extending toward both sides of the latch arm 132 and is used to cooperate with the limiting protrusion 121 to prevent the latch 131 from disengaging in the opposite direction. The locking arm 132 and the locking hook 133 are preferably integrally connected elastic plastic parts. During assembly, the locking arm 132 moves along the channel between the two limiting protrusions 121 until the locking hook 133 is guided along the guide ramp 122 to the side of the limiting protrusion 121 away from the second housing 13. When the latch 131 is inserted into place, the side surface of the locking hook 133 facing the locking arm 132 abuts against the end face of the limiting protrusion 121 to restrict the latch 131 from retracting, while the locking arm 132 is constrained within the lateral space formed by the two limiting protrusions 121.

[0030] The outer casing 1 also includes a cover 14, which covers the end of the first casing 12 away from the second casing 13. The cover 14 covers the outer periphery and end face of the first casing 12. One end of the pin 2 extends through the cover 14 for connection with an external circuit. The other end of the pin 2 is covered by the cover 14. The covered end of the pin 2 forms a dustproof sealing area through the shielding of the cover 14 to prevent impurities from entering the gap between the pin 2 and the casing.

[0031] The linkage rod 3 protrudes from the first housing 12. The end face of the cover 14 must allow the linkage rod 3 to move. Since the linkage rod 3 will form a through hole by moving through the end face of the first housing 12, the component of the cover 14 that covers the linkage rod 3 is preferably an elastic sealing element 134. The sealing element 134 covers the through hole and maintains a dynamic seal. The sealing element 134 can be implemented using a rubber ring or a silicone gasket. The sealing element 134 can adopt a completely closed structure to completely enclose the linkage rod 3. Alternatively, a clearance hole can be retained on the sealing element 134 for the linkage rod 3 to pass through. In this case, the diameter of the hole in the sealing element 134 forms an interference fit with the outer diameter of the linkage rod 3.

[0032] Reference Figure 2 and Figure 3 A limiting block 123 is provided on the outside of the first housing 12, and a limiting groove 141 is formed on the housing cover 14. One end of the limiting block 123 and the pin 2 protrudes from the limiting groove 141. The limiting block 123 is located on one side of the end of the pin 2 that protrudes from the housing cover 14. One side of the limiting block 123 abuts against the pin 2, and the other side of the limiting block 123 abuts against the groove wall of the limiting groove 141. The limiting block 123 is relatively fixed in the limiting groove 141 to limit the lateral displacement of the housing cover 14. At the same time, the limiting block 123 provides support for the pin 2, improving the structural strength of the pin 2.

[0033] Reference Figure 2 and Figure 4 On the side wall of the sliding cavity 11 facing the opening of the sliding cavity 11, there is an abutment protrusion 111 for the pin 2 to abut against. The abutment protrusion 111 extends along the cavity wall of the sliding cavity 11, covering the contact area between the pin 2 inside the sliding cavity 11 and the cavity wall of the sliding cavity 11. This allows the pin 2 to maintain effective contact with the actuating spring 41 through the support of the abutment protrusion when subjected to external vibration or lateral force generated by the movement of the slider 4. (See attached diagram) Figure 3 When assembling pin 2, after the limiting block 123 passes through the limiting groove 141, the cover 14 is placed on the first housing 12, and then pin 2 is inserted through the limiting groove 141 into the slot on the first housing 12 for pin 2 installation.

[0034] Reference Figure 3 and Figure 5The second housing 13 protrudes away from the first housing 12 to form a receiving cavity 135 for accommodating the reset member 5. The end face of the receiving cavity 135 away from the sliding cavity 11 forms the bottom wall of the receiving cavity 135. One end of the reset member 5 abuts against the sliding member 4, and the other end of the reset member 5 abuts against the bottom wall of the receiving cavity 135. The receiving cavity 135 is used to limit the displacement path of the reset member 5 and provide support for the reset member 5, preventing the reset member 5 from shifting or detaching during deformation. Correspondingly, the fixing base 42 may also be provided with a chamber for installing the reset member 5. The chamber on the fixing base 42 and the receiving cavity 135 together form a closed chamber for installing the reset member 5, thereby better limiting the displacement path of the reset member 5. The reset member is preferably a spring. The receiving cavity 135 is directly formed by the second housing 13, so that the installation space of the reset member 5 is directly formed on the housing structure, eliminating the need for additional fixing and installation structures for the reset member 5, simplifying the processing technology and installation process.

[0035] This application also discloses a side-support switch, which includes a switch assembly and a housing 6 as described above. One end of the housing 6 has a mounting cavity 61 for mounting the switch assembly. The switch assembly includes a first housing 12, a second housing 13, a cover 14, a connecting rod 3, and a pin 2. The first housing 12 and the second housing 13 are detachably connected. The cover 14 covers the end of the first housing 12 away from the second housing 13. The connecting rod 3 is movably connected to the end of the first housing 12 away from the second housing 13. The pin 2 passes through and is fixed on the first housing 12, with one end extending out of the cover 14 to connect to an external circuit. The second housing 13 has a snap-fit ​​protrusion 136, and the cavity wall of the mounting cavity 61 has a slot 62 for the snap-fit ​​protrusion 136 to engage. When the switch assembly is inserted into the mounting cavity 61, the snap-fit ​​protrusion 136 is compressed and undergoes elastic deformation before engaging into the slot 62, thereby fixing the switch assembly relatively to the housing 6.

[0036] The implementation principle of a switch assembly and a side-support switch according to an embodiment of this application is as follows: A sliding member 4 is installed in a sliding cavity 11, a reset member 5 is installed in a receiving cavity 135, and a second housing 13 covers the opening end of a first housing 12, with a limiting protrusion 121 and a latch 131 engaging to prevent the second housing 13 from detaching from the first housing 12. A cover 14 covers the end of the first housing 12 away from the second housing 13, and a limiting block 123 is relatively restricted within a limiting groove 141 to prevent the cover 14 from detaching laterally from the first housing 12. A sealing member 134 seals the connection between the connecting rod 3 and the cover 14. After assembling the first housing 12, the second housing 13, and the cover 14, one end of the pin 2 is inserted into the first housing 12 through the limiting groove 141, and one end of the pin 2 protrudes from the cover 14 to connect to an external circuit, while the other end of the pin 2 is covered by the cover 14. Insert the assembled switch assembly into the mounting cavity 61, so that the snap-fit ​​protrusion 136 snaps into the slot 62 to achieve relative fixation between the switch assembly and the housing 6.

[0037] 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.
