Damping type electronic accelerator pedal

Abstract

The invention discloses a damping type electronic accelerator pedal, which comprises a rocker arm, a shell, a cover shell, a spring, a bracket, a movable block and an angle detecting component. One end of the rocker arm extends into the shell to be rotatably mounted on a shaft on a side wall surface of the shell, the cover shell is fixedly connected with the shell, an assembling hole is arranged at one end, which extends into the shell, of the rocker arm, the movable block is inserted into the assembling hole from an opening at the upper end of the assembling hole and is in clearance fit with the inside of the assembling hole, the top surface of the movable block matches with an arc-shaped top wall surface of the shell, the bracket extends into the assembling hole from an opening at the lower end of the assembling hole and is sleeved on the shaft of the side wall surface of the shell, a spiral surface is disposed on the bracket and matches with the lower surface of the movable block, one end of the bracket is connected with the rocker arm while the other end of the bracket is connected with one end of the spring, and the other end of the spring is limited by the aid of a top wall of the shell. By the aid of self-elasticity of the spring is transmitted to the movable block via the bracket, so that damping force in the direction opposite to that of the elasticity of the spring is generated by the movable block and the shell, and accurate rebounding of the spring is not affected.

Description

technical field [0001] The invention relates to the technical field of electronic accelerator pedals, in particular to a damping type electronic accelerator pedal. Background technique [0002] At present, the rapid development of automotive electronics and various sensors have brought automobiles into the era of intelligent comprehensive control. The accelerator pedal has evolved from a pull-wire type to a variable resistance angle sensor, and then to a non-contact angle sensor. The brain ECU of the car senses the accelerator operation and comprehensively controls the accelerator opening, intake air volume, supercharger, exhaust gas purification treatment, etc. etc., adjust the state of the car to the optimal operation. [0003] The non-contact electronic accelerator pedal has a common problem that is difficult to solve: it lacks the blocking feeling of the pull-wire accelerator pedal, and generally uses a spring to return, and there is a floating feeling when the foot is ...

AI Technical Summary

Problems solved by technology

[0003] The non-contact electronic accelerator pedal has a common problem that is difficult to solve: it lacks the blocking feeling of the pull-wire accelerator pedal, and generally uses a spring to return. When the foot controls the accelerator, there is a floating feeling. For example, the driver must control the accelerator to At the position of 2000 rpm, the electronic accelerator pedal always fluctuates up and down from 1800 to 2200 rpm. The driver's foot needs to frequently fine-tune the accelerator position, so it is difficult to control the accelerator stably and accurately. will feel very tired
