Electronic type accelerator pedal of automobile

Abstract

The invention discloses an electronic type accelerator pedal of an automobile. The electronic type accelerator pedal comprises a pedal arm, a shell, a return spring group and a rotating shaft, wherein the return spring group and the rotating shaft are installed in the shell; the pedal arm comprises a long arm part stretching out of the shell and a short arm part arranged in the shell; the return spring group is formed by sheathing two cylindrical helical springs; a sliding block is arranged between the end part far away from the rotating shaft, of the short arm part and the inner wall of the shell; the sliding block is slidably connected with the inner wall of the shell; and the sliding block is clamped with the short arm part of the pedal arm; and further, a foam isolation pad is installed between the two cylindrical helical springs, thereby preventing the two springs from mutually colliding in the movement process. The electronic type accelerator pedal provided by the invention can be smoothly and successfully reset, thus the operation comfortable sensation of driving personnel is enhanced.

Description

technical field [0001] The invention relates to an automobile electronic accelerator pedal. Background technique [0002] With the rapid development of the automobile industry, automobile drivers have higher and higher requirements for the comfort of vehicle operation. The driver of the car applies force to the electronic accelerator pedal to open the accelerator of the car. The currently used electronic accelerator pedal, the pedal arm returns to its position by the restoring tension of a single return spring. Once the driver's foot is separated from the pedal arm, the return spring quickly acts on the pedal arm, and the pedal arm returns too fast, which makes the driver feel very Discomfort; In addition, due to the limited service life of the spring, the return of the accelerator of the car cannot be guaranteed if the spring fails. Realizing the gentle and smooth return of the electronic accelerator pedal is a technical problem that needs to be solved urgently. Content...
