Detailed Implementation

[0038] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0039] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0040] The directional and positional terms used in this utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0041] An automotive switch with pull-up and push-down functions includes a housing assembly, a drive assembly, and a circuit assembly. Figures 1-3 As shown, the housing assembly includes an upper housing 1 and a bottom cover 2, which are connected to form a switching chamber. The drive assembly includes an operating element 3, an upward pull bracket 4, a downward press bracket 5, and an elastic reset element 6. Figure 4 As shown, the circuit assembly 7 includes a circuit board 701 and a pull-up trigger switch 702, a push-down trigger switch 703, an indicator light 704, and a wiring component 705 fixed on the circuit board 701.

[0042] like Figure 3As shown, the operating element 3 is confined within the switch chamber, allowing it to slide only vertically. The plane containing the circuit board 701 is horizontally oriented. The pull-up trigger switch 702 and the push-down trigger switch 703 are connected to the upper surface of the circuit board 701. The pull-up bracket 4 and the push-down bracket 5 are both located above the circuit board 701. Figure 5 As shown, the pull-up bracket 4 has a pull-up drive part 401, a first hinge shaft 402, and a pull-up trigger part 403 connected in sequence. The first hinge shaft 402 is rotatably fixed in the housing assembly, allowing the pull-up bracket 4 to rotate around the first hinge shaft 402 in the switch chamber. Figure 7 As shown, the operating member 3 is provided with an upward pulling part 301, the upward pulling drive part 401 is located above the upward pulling part 301, and the upward pulling trigger part 403 is provided corresponding to the upward pulling trigger switch 702. When the operating member 3 slides upward in the longitudinal direction, the upward pulling part 301 drives the upward pulling trigger part 403 to move upward, the upward pulling bracket 4 rotates around the first hinge axis 402, and the upward pulling trigger part 403 moves downward, triggering the upward pulling trigger switch 702 below. Figure 6 As shown, the pressing bracket 5 includes a pressing drive unit 501, a pressing trigger unit 502, and a second hinge shaft 503 connected in sequence. The second hinge shaft 503 is rotatably fixed inside the housing assembly, allowing the pressing bracket 5 to rotate around the second hinge shaft 503 within the switching chamber. Figure 7 As shown, the operating member 3 is provided with a pressing action part 302, and the pressing drive part 501 is located below the pressing action part 302. The pulling trigger part 403 is arranged corresponding to the pulling trigger switch 702. When the operating member 3 slides down in the longitudinal direction, the pressing action part 302 drives the pressing drive part 501 to move down, the pulling bracket 4 rotates around the second hinge axis 503, and the pressing trigger part 502 moves down, triggering the pressing trigger switch 703 below. Alternatively, the circuit board 701 can be placed above the pulling trigger switch 702 and the pressing trigger switch 703. Relatively speaking, this method requires more space in the horizontal direction to install the circuit board 701.

[0043] Specifically, such as Figure 7 As shown, the lower end of the control member 3 is provided with a crossbar 303. The upper pull action part 301 and the lower press action part 302 are the upper and lower ends of the crossbar 303, respectively. One end of the upper pull bracket 4 and one end of the lower press bracket 5 extend to the upper and lower ends of the crossbar 303, respectively, to form the upper pull drive part 401 and the lower press drive part 501.

[0044] The elastic reset element 6 is disposed in the area between the pull-up bracket 4, the press-down bracket 5, and the circuit board 701, and includes a first compression elastic reset structure 601 and a second compression elastic reset structure 602, such as... Figure 5As shown, the pull-up bracket 4 has a pull-up reset drive part 404 that cooperates with the first compression elastic reset structure 601 on the side of the first hinge shaft 402 away from the pull-up drive part 401, as shown. Figure 6 As shown, the pressing bracket 5 has a pressing reset driving part 504 that cooperates with the second compression elastic reset structure 602 on the side of the second hinge shaft 503 near the pressing drive part 501. Figure 9 As shown, when the operating member 3 slides upward in the longitudinal direction under the action of an external force, it drives the upper pull bracket 4 to rotate around the first hinge axis 402, and the upper pull reset drive part 404 presses down on the first compression elastic reset structure 601. At this time, the operating member 3 loses the action of external force, and under the drive of the elastic reset force of the first compression elastic reset structure 601, it pushes the upper pull bracket 4 to rotate and reset around the first hinge axis 402. When the operating member 3 slides downward in the longitudinal direction under the action of an external force, it drives the lower press bracket 5 to rotate around the second hinge axis 503, and the lower press reset drive part 504 presses down on the second compression elastic reset structure 602. At this time, the operating member 3 loses the action of external force, and under the drive of the elastic reset force of the second compression elastic reset structure 602, it pushes the lower press bracket 5 to rotate and reset around the second hinge axis 503.

[0045] Specifically, such as Figure 8 As shown, the elastic reset component 6 is a rubber pad. The elastic reset component 6 is positioned above the circuit board 701 and has a through hole 603 for the pull-up trigger switch 702 and the push-down trigger switch 703 to pass through. The first compression elastic reset structure 601 and the second compression elastic reset structure 602 are both integrally formed on the elastic reset component 6 as upwardly protruding elastic rubber caps. Other elastic structures, such as compression springs, torsion springs, or spring sheets, can also be used for the first compression elastic reset structure 601 and the second compression elastic reset structure 602. These elastic structures all require separate mounting structures, and the first compression elastic reset structure 601 and the second compression elastic reset structure 602 need to be installed separately. In this embodiment, a rubber sleeve is used to integrate the first compression elastic reset structure 601 and the second compression elastic reset structure 602 into a single part for easy assembly.

[0046] Furthermore, the pull-up bracket 4 includes two first levers 405. The first hinge shaft 402 is a protruding post protruding from the middle of the outer wall of the first lever 405. One end of the first lever 405 constitutes the pull-up drive part 401, and the other end is connected through the first connecting rod 406. The middle part of the first connecting rod 406 is disposed above the pull-up trigger switch 702 to form the pull-up trigger part 403, and both ends are disposed above the first compression elastic reset structure 601 to form the pull-up reset drive part 404. The press-down bracket 5 includes two second levers 505. One end of the second lever 505 constitutes the press-down drive part 501, and the other end is connected through the second connecting rod 506. The second hinge shaft 503 is disposed on the second connecting rod 506. The middle parts of the two second levers 505 are connected through the third connecting rod 507. The middle part of the third connecting rod 507 is disposed above the press-down trigger switch 703 to form the press-down trigger part 502, and both ends are disposed above the second compression elastic reset structure 602 to form the press-down reset drive part 504. Figure 9 As shown, the distance between the two first levers 405 is greater than the distance between the two second levers 505, and the two first levers 405 are located outside the two second levers 505, as shown. Figure 10 As shown, two first support columns 101 and two second support columns 102 extend downward within the upper housing 1. The two first support columns 101 are located outside the two second support columns 102. The first support column 101 is provided with a first hinge hole 103 that forms a hinge limit engagement with the first hinge shaft 402. The second support column 102 is provided with a second hinge hole 104 that forms a hinge limit engagement with the second hinge shaft 503. The second hinge shaft 503 is formed by two annular grooves on the second connecting rod 506. The axial position limit of the upper pull bracket 4 and the lower press bracket 5 is achieved by the cooperation of the two first support columns 101 and the two first levers 405, and the cooperation of the two second support columns 102 and the two annular grooves, respectively, and the space is fully utilized to form a stable drive transmission structure.

[0047] Furthermore, both the first hinge hole 103 and the second hinge hole 104 are open at the bottom and the width of the opening is smaller than the outer diameter of the first hinge shaft 402 and the second hinge shaft 503, respectively. The first support column 101 and the second support column 102 are provided with a certain elasticity so that the first hinge shaft 402 and the second hinge shaft 503 can be inserted and installed in a limited position.

[0048] Furthermore, such as Figure 7 , Figure 11 As shown, the two side walls of the operating member 3 are provided with first limiting blocks 304, and the two inner walls of the upper housing 1 are provided with second limiting blocks 105. The second limiting blocks 105 are located above the first limiting blocks 304 and limit their upward travel.

[0049] Furthermore, such as Figure 7 , Figure 11 As shown, the indicator light 704 is positioned below the control component 3. The upper housing 1 has a hollow light guide column 106 corresponding to the indicator light 704. The control component 3 has a longitudinally arranged light-transmitting hole 305 corresponding to the light guide column 106 for light to pass through, so that the light from the indicator light 704 can pass through.

[0050] The connector 705 is connected to the lower surface of the circuit board 701, and the bottom cover 2 is provided with a wiring hole for the connector 705 to pass through.

[0051] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
