Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0036] Embodiment 1:

[0037] This embodiment provides a rearview mirror adjustment switch, including:

[0038] A switch box 1, wherein a plurality of first through holes 5 are arranged on the top of the switch box 1;

[0039] A circuit board 2 is installed in the switch box 1, and a plurality of micro switches 6 passing through a plurality of first through holes 5 are electrically connected to the circuit board 2;

[0040] The button assembly 3 is arranged on the top of the switch box 1, and the bottom of the button assembly 3 abuts against the tops of the plurality of micro switches 6;

[0041] The cover plate 4 is arranged on the top of the switch box 1. The cover plate 4 is provided with a plurality of second through holes 7 corresponding to the key assembly 3. The top of the key assembly 3 passes through the plurality of second through holes 7.

[0042] Among them, the button assembly 3 includes a rearview mirror adjustment key 31, two rearview mirror selection keys 32 respectively located on both sides of the rearview mirror adjustment key 31, a third through hole 8 is provided on the rearview mirror adjustment key 31, and the button assembly 3 also includes a rearview mirror folding key 33 arranged in the third through hole 8, the rearview mirror selection key 32 and the rearview mirror adjustment key 31 are connected by two elastic connecting strips 34, and the elastic connecting strip 34 includes a first connecting strip 341, a second connecting strip 342 and a third connecting strip 343 which are bent and connected in sequence, and an annular convex portion 9 located below the rearview mirror selection key 32 and the rearview mirror folding key 33 is provided on the top of the switch box 1, and the rearview mirror selection key 32 and the rearview mirror folding key 33 are respectively inserted on the annular convex portion 9, and a plurality of limit grooves 10 are opened on the annular convex portion 9 located below the rearview mirror folding key 33, and a limit portion 13 is provided on the rearview mirror folding key 33 that is clamped in the limit groove 10.

[0043] In the present technical solution, the button assembly 3, the switch box 1 and the cover plate 4 can all be made of plastic materials, the micro switch 6 can be an existing micro switch 6, and the micro switch 6 can be fixed on the circuit board 2 by welding.

[0044] The rearview mirror adjustment key 31 is an integrated structure and can be used to adjust the rearview mirror to rotate up and down and left and right. Figure 1 As shown, by pressing the upper and lower sides of the rearview mirror adjustment key 31, the upper and lower micro switches 6 below it are triggered, and the rearview mirror can be controlled to rotate up and down. By pressing the left and right sides of the rearview mirror adjustment key 31, the left and right micro switches 6 below it are triggered, and the rearview mirror can be controlled to rotate left and right. The rotation angle of the rearview mirror can be controlled by pressing the rearview mirror adjustment key 31 times, and a suitable circuit is designed. For example, pressing the right side once can make the rearview mirror rotate 10 degrees to the right, and pressing it twice can make it rotate 20 degrees to the right.

[0045] The rearview mirror selection key 32 is used to select the left rearview mirror and the right rearview mirror for adjustment. When the rearview mirror selection key 32 on the right side of the rearview mirror adjustment key 31 is pressed, the micro switch 6 below it is triggered, and after the right rearview mirror is selected, the rearview mirror on the right side is adjusted by pressing the rearview mirror adjustment key 31. Conversely, the left rearview mirror can be adjusted by pressing the rearview mirror selection key 32 on the left side.

[0046] Pressing the rearview mirror folding key 33 once triggers the micro switch 6 below it, so that the rearview mirror can be folded back, and pressing it again can reset the rearview mirror.

When the rearview mirror adjustment key 31 is pressed, it can tilt toward one side, and the two elastic connecting strips 34 on the pressed side are stretched and deformed, and the two elastic connecting strips 34 on the opposite side are also stretched and deformed. After releasing the finger, the rearview mirror adjustment key 31 is reset to maintain a horizontal state due to the rebound force of the elastic connecting strip 34.

[0049] The rearview mirror adjustment key 31 is connected to the rearview mirror selection keys 32 on the left and right sides through an elastic connecting strip 34, which can also avoid the risk of one of the keys falling off or lost. On the premise of ensuring that the rearview mirror adjustment key 31 can adjust the rearview mirror in the up, down, left and right directions, the number of button installations can be reduced, saving time and effort.

[0050] The rearview mirror selection key 32 and the rearview mirror folding key 33 are respectively inserted on the annular protrusion 9, which are used to limit and fix the rearview mirror selection key 32 and the rearview mirror folding key 33, ensuring that the rearview mirror selection key 32 and the rearview mirror folding key 33 move in the vertical direction to improve stability.

[0051] Among them, the limiting part 13 of the rearview mirror folding key 33 is clamped in the limiting groove 10. The limiting groove 10 can be a strip groove. The limiting part 13 can slide up and down in the limiting groove 10 to ensure that the rearview mirror folding key 33 will not fall off.
