The multi-function switch assembly at the bottom left side of the steering wheel

Abstract

The invention discloses a multifunctional switch assembly at the left bottom of the steering wheel of an automobile, which includes two parts: an insulating cover and a handle body, wherein the insulating cover is provided with two contact terminals for generating specified electrical signals, and the handle body is provided with Two rotary knobs, two handle arms that are rotated in conjunction with each rotary knob and whose ends respectively abut against the contact terminals, and a connecting portion that guides the ends of the two handle arms to rotate, and the first handle arm is axially disposed through the second Inside the handle arm. In particular, the two handle arms are provided with a spacer cavity on the overlapping section and between the exposed end of the first handle arm and the end of the second handle arm. By applying the multifunctional switch assembly solution of the present invention, the interference between the two handle arms is minimized by improving the end structure of the handle arms, and the reset force of the second handle arm is particularly improved, which can reduce the cost of the switch assembly. Operation failure phenomenon.

Description

technical field [0001] The present invention relates to an automobile multifunctional switch assembly, more specifically, the present invention relates to a new type of switch assembly that minimizes the operation interference between two handle arms in the multifunctional switch assembly at the left bottom of the automobile steering wheel. Background technique [0002] In general, when driving at night or in areas with narrow vision and darkness such as foggy areas, in order to turn on and off the headlights, or when it snows or rains while the vehicle is running, in order to adjust the windshield wiper The wiper ensures the driver's front sight and rear sight, and the car multi-function switch assembly is installed on the car. [0003] As shown in the figure, the automobile multifunction switch assembly 1 of the prior art has a handle body 80 extending in the longitudinal direction on the side of the steering wheel. The movement of the car's headlights and wipers. [000...

AI Technical Summary

Problems solved by technology

[0010] Yet, one implementation example of the automobile multifunction switch assembly of prior art, in order to prevent the front end portion of the first handle arm 60 from swimming in the length direction, it is installed close to the outer surface of the front end portion of the second handle arm 50, and Interference, so there is a problem that the return force of the second rotary knob decreases when the second rotary knob is turned as the first rotary knob N1 is rotated

[0011] As mentioned above, the reduction of the reset force of the second rotary knob 50 not only affects the quality of consumers' emotional evaluation, but also causes related problems caused by product failure.
