Problems solved by technology

However, because this design only has a single-sided gear slot structure, during the rotation of the knob, the internal rotating block will be forced on one side when it rotates together, and the knob will shake slightly and feel unstable.
[0007] In addition, in the above two design schemes, when rotating to the folding gear, there is no corresponding force value feel. If the operator exerts a small force, it is easy for the knob assembly to stay on the middle line of the knob, which cannot make the rear view of the car mirror folding

Abstract

The invention discloses a knob switch structure, which comprises a housing, a swing rod, a rotor and a gear plate. The gear plate comprises a first layer and a second layer. A first through hole is formed in the first layer, and a second through hole is formed in the second layer. The first through hole comprises a smooth gear part and a gear sudden change area. The second through hole and the first through hole are of the same structure. The second through hole rotates by 180 degrees along the axial center line of the first through hole and coincides with the first through hole. The structurefurther comprises a first top column and a second top column. One end of the first top column is fixedly connected with the rotor, and the other end of the first top column slides along the inner wall of the first through hole. One end of the second top column is fixedly connected with the rotor, and the other end of the second top column slides along the inner wall of the second through hole. The first top column and the second top column are symmetrically arranged along the central axis of the rotor. The invention further discloses an automobile. The automobile comprises the knob switch structure. According to the invention, force values can be mutually offset, and the stable and smooth operation at each gear can be realized. The stagnation phenomenon can occur on the surface of the arranged gear abrupt change area at the horizontal position. Therefore, the smooth hand feeling is achieved.

Description

technical field [0001] The invention relates to the technical field of rotary switches, in particular to a rotary switch structure and an automobile. Background technique [0002] At present, there are two kinds of gear feel designs for the left (L) and right (R) mirror selection of the knob-type exterior rearview mirror switch: [0003] 1. When the knob is from "O" gear --> "L" or "R" gear, the force feel changes suddenly when the knob rotates to an angle of about 30°, and then reaches "L" or "R" through a 15° rotation angle When the knob returns from the "L" or "R" position to the "O" position, it is just the opposite. It first turns 15°, then the force value changes abruptly, and then returns to the "O" position through a 30° rotation angle. The sudden change of force feel is at the position of the 2 / 3 angle dividing line of "O" gear --> "L" or "R" gear. [0004] This design is due to the position of the sudden change point of the hand feeling force value at the p...
