DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0017] Reference Figure 1-4As shown, an integrated mounting structure for a handlebar combination switch includes an upper housing 1, a lower housing 2, a circuit board 3, micro switches 4, and a silicone panel 5. The lower housing 2 is provided with a mounting seat 6 for the circuit board 3. Several micro switches 4 are provided and mounted on the circuit board 3. The silicone panel 5 is mounted on the lower housing 2 and secured by the upper housing 1. The silicone panel 5 is provided with several raised cavities 7 corresponding to the positions of the micro switches 4. Several micro switches 4 are respectively mounted below the corresponding raised cavities 7. The upper housing 1 is provided with several windows 8 through which the raised cavities 7 extend. The circuit board 3 is placed on the mounting seat 6 of the lower housing 2. The mounting seat 6 supports and positions the circuit board 3, ensuring the stable position of the circuit board 3 during subsequent assembly and use. Several micro switches 4 are mounted on the circuit board 3, and the position of each micro switch 4 corresponds to the raised cavity 7 on the silicone panel 5. Then, the silicone panel 5 is mounted on the lower housing 2 and then pressed and fixed with the upper housing 1. At this time, the raised cavity 7 on the silicone panel 5 protrudes through the window 8 of the upper housing 1. During operation, when the raised cavity 7 is pressed, it presses the corresponding micro switch 4 downward, causing the micro switch 4 to perform the corresponding switching function. This technical solution simplifies the assembly steps and improves production efficiency.

[0018] The bottom of the silicone panel 5 is provided with a first extension portion 9, which surrounds the outline of the mounting seat 6 and is installed between the mounting seat 6 and the side wall of the lower shell 2. The bottom of the upper shell 1 is provided with a second extension portion 10, which surrounds the outline of the first extension portion 9. The second extension portion 10 is installed between the mounting seat 6 and the side wall of the lower shell 2 and squeezes the first extension portion 9 to form an interference fit. During assembly, the first extension portion 9 plays a preliminary positioning and filling role between the mounting seat 6 and the side wall of the lower shell 2, while the second extension portion 10 squeezes the first extension portion 9 to form an interference fit, making the connection between the silicone panel 5 and the lower shell 2 and upper shell 1 tighter and more secure, effectively preventing the silicone panel 5 from loosening or shifting during long-term use. At the same time, the interference fit can also enhance the sealing of the structure, prevent external dust, water vapor, etc. from entering the interior, protect components such as the circuit board 3 and the micro switch 4, and extend their service life.

[0019] A first sealing portion 11 and a second sealing portion 12 are provided at the bottom of the first extension portion 9. The first sealing portion 11 extends outward to the side wall of the lower shell 2 and is pressed against the lower shell 2 by the first extension portion 9. A sealing groove 13 is provided on the lower shell 2 for the second sealing portion 12 to be embedded in. The first sealing portion 11 fits tightly against the side wall of the lower shell 2 and forms a first sealing line of defense under the pressure of the first extension portion 9, effectively preventing external impurities from entering through the gap between the side wall of the lower shell 2 and the first extension portion 9. The second sealing portion 12 is embedded in the sealing groove 13 and is in close contact with the inner wall of the sealing groove 13, forming a second sealing line of defense, further enhancing the sealing of the overall structure. The double sealing structure improves the waterproof and dustproof performance, and can effectively protect the internal circuit board 3 and micro switch 4 even when used in a humid or dusty environment.

[0020] The first extension portion 9 is provided with a first stepped surface 14 that abuts and cooperates with the upper housing 1. The upper housing 1 is provided with a second stepped surface 15 that cooperates with the first stepped surface 14. The second stepped surface 15 abuts against the first stepped surface 14. The abutment and cooperation between the second stepped surface 15 and the first stepped surface 14 not only serves to position the first extension portion 9 and the upper housing 1, ensuring that the two are accurately positioned during assembly, but also increases the contact area between the upper housing 1 and the silicone panel 5, making the pressing force of the upper housing 1 on the silicone panel 5 more evenly distributed and further enhancing the stability of the installation of the silicone panel 5.

[0021] The circuit board 3 is provided with a number of through-holes for the flow of glue. The solidified glue strengthens the bond between the circuit board 3 and the mounting base 6. When the electric vehicle vibrates during operation, the circuit board 3 is less likely to loosen or shift, thereby ensuring the stable position of the micro switch 4 mounted on the circuit board 3. In this embodiment, the upper shell 1 and the lower shell 2 are ultrasonically welded, resulting in a tight and secure joint between the upper shell 1 and the lower shell 2, which effectively prevents the ingress of dust and moisture.

[0022] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
