Description

Technical Field

[0001] The utility model belongs to the field of electric switches, and in particular relates to a side stand flameout switch. Background Art

[0002] A side stand kill switch is a common safety accessory for electric vehicles, primarily used to ensure the safety of the vehicle when parked. When the side stand of the electric vehicle is lowered so that it contacts the ground, the switch is disconnected, thereby cutting off the power supply to the electric vehicle, preventing the vehicle from accidentally starting or moving while parked, and improving the safety of vehicle use. In order to enhance the connection strength between the rotating body and the external component in the side stand kill switch, a shift block is usually provided protruding from the rotating body. The shift block is plugged into the external component to form a positioning connection, and when the external component rotates, the rotating body is driven to rotate relative to the outer shell. However, in actual use, the existing side stand kill switch is prone to the problem of the shift block breaking, which in turn causes the side stand kill switch to be damaged and fail, significantly shortening its service life.

In actual use, the relative position relationship between the contact piece 2 and the contact piece 2 4 is changed by relative rotation between the rotating body 2 and the shell 1; the rotating body 2 includes a central axis The middle shaft portion 21 and the flange portion 22, the middle shaft portion 21 is made of metal, and the middle shaft portion 21 includes an upper shaft portion 211, a connecting portion 212 and a lower shaft portion 213 arranged in sequence from top to bottom, the flange portion 22 is made of plastic and is injection-molded as one piece with the connecting portion 212, the contact piece 24 is mounted on the flange portion 22, the upper end of the upper shaft portion 211 is integrally provided with a shift block 214 protruding upward, and the root of the shift block 214 in the circumferential direction of the rotating body 2 ( Figure 4 The width at point a) increases gradually from top to bottom; the combination of the flange portion 22 made of plastic and the central axis portion 21 made of metal can reduce the weight of the rotating body 2 while ensuring the overall strength of the rotating body 2, and since the flange portion 22 is subjected to relatively small force in actual use, the use of plastic material to make the flange portion 22 will not affect the performance of the rotating body; and the contact piece 24 is installed on the flange portion 22, which can achieve insulation between the contact piece 24 and the central axis portion 21, and by optimizing the structure at the root of the shift block 214, the stress concentration is dispersed and the strength of the root of the shift block 214 is significantly enhanced; the improvement effectively avoids the problem of breakage of the root of the shift block 214 that is prone to occur in actual use, thereby extending the service life of the side support ignition switch and improving the reliability and durability of the product.

[0028] like Figure 2 and Figure 4 As shown, the rotating body 2 is further provided with a rounded transition between the two sides of the root of the shift block 214 and the upper end shaft portion 211 in the circumferential direction, or the arc transition can be changed to an oblique angle transition.

[0029] In practical applications, the central axis portion 21 is preferably made of zinc alloy, but may also be made of aluminum alloy, stainless steel, etc.

[0030] See Figure 4 and Figure 5 The housing 1 has an annular step 12, the contact piece 1 3 is fixed on the annular step 12, the bottom of the flange portion 22 has a mounting surface 23 located above the annular step 12, and the contact piece 2 4 is mounted on the mounting surface 23, so that the contact piece 2 4 and the contact piece 1 3 are arranged opposite to each other in an upper and lower direction; if the contact piece 1 3 is integrally injection-molded on the annular step 12, it can ensure that the contact piece 3 is reliably and fixedly connected to the annular step 12.

[0031] See Figure 4 、 Figure 6 and Figure 7 As shown, to facilitate the installation of contact piece 2 4 on flange portion 21, the mounting surface 23 is provided with several upwardly recessed positioning holes 231 and several spring positioning slots 232. Contact piece 2 4 is integrally provided with positioning pins 41 that plug into the positioning holes 231. Springs 5 ​​are embedded in the spring positioning slots 232. The lower end of the spring 5 abuts against contact piece 2 4 to maintain the downward movement of contact piece 2 4. The engagement of the positioning pins 41 with the positioning holes 231 ensures that contact piece 2 4 is securely positioned on flange portion 22. The springs 5 ​​provide a downward elastic force to contact piece 2 4, ensuring stable and effective contact between contact piece 2 4 and contact piece 1 3. Furthermore, contact points 42 are stamped into contact piece 2 4 at positions corresponding to the springs 5.

[0032] like Figure 6 and Figure 7 As shown, the contact piece 2 4 is an arc-shaped structure, and the positioning pins 41 are provided at both ends and the middle of the contact piece 2 4. A positioning hole 231 is provided on the mounting surface 23 corresponding to each positioning pin 41. By providing positioning pins 41 at different positions on the contact piece 2 4 to cooperate with the positioning holes 231 at corresponding positions, the connection between the contact piece 2 4 and the flange portion 22 can be enhanced.

[0033] See Figure 4 In order to realize the convenient connection between the temple ignition switch and the external wire, a wiring socket 13 is provided on the outside of the housing 1, and a pin terminal 30 is provided in the wiring socket 13. The pin terminal 30 and the contact piece 13 are integrally formed. The plug of the external wire can be connected to the wiring socket 13 to realize the connection.

[0034] In order to improve the sealing performance of the side stand ignition switch, an upper sealing ring 6 and a lower sealing ring 7 are embedded in the shell 1. The upper sealing ring 6 seals the gap between the upper end shaft 211 and the shell 1, and the lower sealing ring 7 seals the gap between the lower end shaft 213 and the shell 1. By sealing from the upper and lower ends of the shell 1 by the upper sealing ring 6 and the lower sealing ring 7, double sealing can be achieved, thereby preventing dust and impurities from entering the interior of the shell 1 and ensuring product performance.

[0035] As an optimization solution, the contact piece 2 4 is integrally injection-molded on the plastic part 14, and the plastic part 14 and the housing 1 are integrated through secondary injection molding; during production, the contact piece 2 4 and the plastic part 14 are injection-molded as a whole through one injection molding, and then the molded plastic part 14 and the housing 1 are combined together through secondary injection molding to complete the manufacture of the entire component. This design can enhance the structural strength of the component and avoid seams caused by assembly; it can also ensure the position accuracy of the contact piece 2 4 and ensure the performance of the product.
