Detailed Implementation

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0024] The side-support switch of this utility model embodiment is used in electric vehicles or motorcycles, and its structure is as follows: Figures 1 to 3 As shown, it includes a housing 1 and a rotating shaft 2. The rotating shaft 2 is rotatably mounted inside the housing 1. A stationary contact piece 11 is fixed inside the housing 1. A movable contact piece 21 corresponding to the stationary contact piece 11 is mounted on the rotating shaft 2. In actual use, the relative positional relationship between the stationary contact piece 11 and the movable contact piece 21 is changed by the relative rotation between the rotating shaft 2 and the housing 1, thereby realizing the switch control function. In order to improve the waterproof performance of the product, sealing rings 4 can be provided between the upper end of the rotating shaft 2 and the housing 1 and between the lower end of the rotating shaft 2 and the housing 1 to prevent water and dust from entering through the gap between the housing 1 and the rotating shaft 2. The side support inside the switch affects the switching performance; furthermore, the end of the wire 3 is connected to the stationary contact piece 11 and injection molded and fixed inside the housing 1. The housing 1 has an integrally formed encapsulation part 12 that protrudes outward and is integrated with the outer surface of the wire 3. By fixing the stationary contact piece 11 and the wire 3 to the housing 1 through injection molding, the structure is stable. Moreover, by integrating the encapsulation part 12 with the outer surface of the wire 3, gaps at the connection between the wire and the housing 1 can be avoided. This helps to improve the sealing performance of the product, prevent moisture and dust and other impurities from entering the interior, protect the internal circuits and mechanical parts, and thus ensure the performance of the product.

[0025] Preferred options, see Figure 3As shown, the stationary contact 11 is integrally injection molded onto the primary plastic part 13. The stationary contact 11 has a terminal 14 extending out of the primary plastic part 13. After the terminal 14 is connected to the wire 3, it is integrally injection molded with the housing 1 through a secondary injection molding process. During production, the stationary contact 11 and the primary plastic part 13 are injection molded into a whole through a primary injection molding process. Then, the wire 3 is connected to the stationary contact 11. The housing 1 is injection molded into a whole with the connected wire 3 and the stationary contact 11 through a secondary injection molding process, thus completing the manufacturing of the entire component. This design can enhance the structural strength of the component, ensure the positional accuracy of the stationary contact 11, and avoid seams caused by assembly, which is beneficial to improving electrical performance.

[0026] Combination Figures 4 to 6 As shown, the rotating shaft 2 is provided with a plurality of recessed insertion holes 23 and a plurality of mounting grooves 22. The movable contact piece 21 is integrally provided with a pin 24 that is inserted into the insertion hole 23. A spring 25 is installed in the mounting groove 22. The outer end of the spring 25 abuts against the movable contact piece 21 so that the movable contact piece 21 maintains a tendency to move towards the stationary contact piece 11. The insertion and cooperation between the pin 24 and the insertion hole 23 can realize the reliable positioning of the movable contact piece 21 on the rotating shaft 2, and the spring 25 provides elastic force to the movable contact piece 21 to ensure that the movable contact piece 21 and the stationary contact piece 11 can form a stable and effective contact. Moreover, the limiting of the spring 25 by the mounting groove 22 can prevent the spring 25 from shifting.

[0027] Furthermore, such as Figure 5 As shown, at least one of the sockets 23 is provided with a mounting plate 231, and the pin 24 is provided with a hook 241 that engages with the mounting plate 231. Due to the presence of the spring 25, the movable contact piece 21 may easily detach from the rotating shaft 2, which is not conducive to the assembly between the rotating shaft 2 and the housing 1. Specifically, during assembly, the pin 24 is inserted into the socket 23 and engages with the mounting plate 231 through the hook 241, thereby allowing the pin 24 to move within the socket 23 without detaching. This can prevent the movable contact piece 21 from detaching from the rotating shaft 2 when the rotating shaft 2 is installed into the housing 1, thereby improving the ease of assembly.

[0028] See Figures 4 to 6 As shown, the rotating shaft 2 has stop blocks 26 at both ends corresponding to the moving contact piece 21 in its rotation direction. The stop blocks 26 can strengthen the limiting of the moving contact piece 21 and ensure that the rotating shaft 2 drives the moving contact piece 21 to rotate when it rotates. Moreover, the moving contact piece 21 has pins 24 at positions corresponding to the stop blocks 261. The rotating shaft 2 has a socket 23 at the stop blocks 26. The stop blocks 26 have a sloping guide surface 261 facing the socket 23. When the moving contact piece 21 is installed on the rotating shaft 2, the sloping guide surface 261 can guide the pins 24 at the end of the moving contact piece 21 to be inserted into the socket 23 along the sloping guide surface 261.

[0029] As a preferred embodiment of the above, see Figure 5 As shown, the rotating shaft 2 has a metal central shaft 27 and a plastic flange 28 integrally injection molded with the metal central shaft 27. The plastic flange 28 is arranged around the outer periphery of the metal central shaft 27, and the movable contact piece 21 is mounted on the plastic flange 28. The metal central shaft 27 is preferably made of zinc alloy, but aluminum alloy, stainless steel, etc. can also be used. By combining the plastic flange 28 with the metal central shaft 27, the overall strength of the rotating shaft 2 can be guaranteed while reducing the weight of the rotating shaft 2. Moreover, since the plastic flange 28 is subjected to relatively small forces in actual use, the use of the plastic flange 28 will not affect the performance of the rotating shaft 2. Furthermore, mounting the movable contact piece 21 on the plastic flange 28 can achieve insulation between the movable contact piece 21 and the metal central shaft 27.

[0030] like Figure 1 and Figure 2 As shown, the upper end of the rotating shaft 2 is provided with a lever 20 that protrudes outward along the axial direction; in the circumferential direction of the rotating shaft 2, the two sides of the root a of the lever 20 are connected to the rotating shaft 2 with rounded corners or beveled corners, so that the width of the root a of the lever 20 gradually increases from top to bottom. This can enhance the strength of the lever 20, making it less prone to breakage under force, improving the performance of the product, and making it more reliable and durable.

[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
