[0002] With the development of society, people are paying more and more attention to the comfort and maneuverability of cars. In order to meet people's requirements, the human-machine interface must be beautiful in appearance, comprehensive in function, quick in response, good in feel and durable. In civilian cars, the shift function is limited to the operation of the shift lever. Influenced by F1 racing cars and high-end sports cars, a shift paddle switch is added behind the steering wheel to replace the manual shift lever function. The advantage of the shift paddle assembly is that the driver does not need to take his hands off the steering wheel, but only uses his fingers to move the left and right shift paddles to control the upshift and downshift of the transmission, which makes the shifting faster and more convenient.

[0003] The shift paddle switches of some existing automobile steering wheels are arranged on the back of the steering wheel of the vehicle, so the driver's hands often touch the shift paddle switches, which makes it easy for the driver to shift gears without knowing it, so that the vehicle speed cannot be accurately controlled and the safety performance of the vehicle is reduced.

[0007] Furthermore, an anti-skid groove is provided on the upper end surface of the paddle upper cover, and a plurality of groups of anti-skid grooves are provided, and the plurality of groups of anti-skid grooves are equidistantly provided.

[0008] Furthermore, the front and rear end surfaces of the paddle base can be slidably connected to the inner wall of the mounting base, the outer diameter of the pin shaft is equal to the inner diameter of the hinge hole, and the two can be rotatably connected to each other.

[0009] Furthermore, the specifications of the positioning slide groove match those of the positioning slide block, and the two can fit and slide together, and the positioning slide block is configured as a semicircular arc structure.

[0010] Furthermore, two groups of positioning sliders are provided, the two groups of positioning sliders are equal in size, and are symmetrically fixed on the front and rear end surfaces of the paddle base.

[0011] Furthermore, the tail end of the movable contact rod is configured as an arc structure.

[0012] The beneficial effects of the utility model are as follows: the utility model provides a shift paddle switch for a car steering wheel.
