It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.
[0043] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.
[0044] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. Example

[0075] In some embodiments, a vehicle is also provided, on which the automobile rearview mirror switch structure in any of the above embodiments is installed.
[0076] The automobile rearview mirror switch structure in the above embodiment is particularly suitable for being used as a switch for an automobile electric rearview mirror.
[0077] The automobile rearview mirror switch structure in the above embodiment is installed on the vehicle to control the electric rearview mirror. In actual use, when the rearview mirror needs to be adjusted in the four directions of up, down, left or right, the operator chooses to turn the knob 31 of the knob assembly 3 upward, down, left or right, the knob 31 drives the shaft 32, the shaft 32 drives the shift block 5, the shift block 5 drives the fixed column 10 to move, the relative position of the third magnet 11 on the fixed column 10 and the iron sheet 13 changes, there is a certain magnetic force between the third magnet 11 and the iron sheet 13, and the change of magnetic attraction improves the operating feel of shifting the gear. At the same time, the second magnet 6 adapted on the shift block 5 also changes its position with the movement of the shift block 5.

At the same time, the first magnet 4 installed at the lower end of the shaft 32 causes the N and S magnetic poles to change as the shaft 32 rotates. At this time, the magnetic field change signal is recognized by the first Hall chip 8 and transmitted to the control system, thereby realizing the switching function of the left / right selection, folding and heating functions of the rearview mirror.
[0078] In summary, the automobile rearview mirror switch structure of the utility model is cleverly provided with a first magnet on the knob assembly, and a first Hall chip matching the first magnet is precisely configured on the circuit board of the base. By rotating the knob assembly, the N and S magnetic poles of the first magnet change, so that the first Hall chip recognizes the magnetic field change signal and transmits it to the control system, thereby realizing the left / right selection, folding and heating functions of the rearview mirror. At the same time, by providing a stop block adapted to the knob assembly, a second magnet is provided on the stop block, and a second Hall chip matching the second magnet is configured on the circuit board of the base. By pulling the knob assembly, the knob assembly drives the position of the stop block to change, and the second magnet changes with the position change of the stop block, so that the second Hall chip transmits the corresponding signal to the control system by identifying the position change of the second magnet, thereby realizing the adjustment function of the rearview mirror in the four directions of up, down, left and right. Therefore, the first magnet is directly provided on the knob assembly, and the second magnet is directly provided on the stop block. Not only the assembly dimension chain between the components is significantly shortened, but also the reliability of the switch function is improved. It also effectively avoids the problem of wear caused by mutual friction between parts during the toggle or rotation of the switch, thereby greatly improving the durability of the switch. It solves the problems of insufficient durability and poor functional reliability of existing rearview mirror switches, and has promotion and application value in the field of automotive parts technology.
