Anti-pouring type brake pedal device

Abstract

The invention discloses an anti-pouring brake pedal device. The anti-pouring brake pedal device comprises a pedal seat; a connecting shaft is arranged on the pedal seat; the connecting shaft is rotationally connected with a long supporting arm and a pedal arm; a sliding groove is formed in the end part of the long supporting arm in the axial direction; a limiting clamping groove is formed in the end part of the sliding groove; a rotary shaft is arranged at the end part of the pedal arm; a short supporting arm is arranged on the rotary shaft in a sleeving mode; one end of the short supporting arm is connected with a cylindrical pin; a limiting block arranged in the limiting clamping groove is arranged on the cylindrical pin; the limiting block can rotate along with the cylindrical pin to move in the sliding groove; the end part of the cylindrical pin is fixedly connected with a rotary arm; a spring is connected between the rotary arm and the rotary shaft; the pedal seat is provided with a trigger part; the trigger part is arranged on one side of the rotary arm; and the rotary arm can be pushed to rotate when the trigger part rotates. According to the anti-pouring brake pedal device, a brake pedal power transmission route is integrated on the pedal arm, a stable geometric structure can be realized, the power transmission is stable before triggering, the energy transmission of the pedal arm can be effectively disconnected after triggering, passengers are protected, and the safety performance is high.

Description

technical field [0001] The invention relates to the technical field of automobile brake devices, in particular to an anti-tilting brake pedal device. Background technique [0002] With the continuous improvement of people's living standards, cars have brought a lot of convenience to people's travel. At the same time, with the continuous upgrading of products in the automotive market, the requirements for vehicle collision safety are becoming increasingly stringent, especially when it comes to passive safety. Human body protection in the field, etc. [0003] Some of the cars have the following phenomenon. When the car collides, the control mechanism in the cockpit will cause damage to the driver, especially the brake pedal will cause damage to the human calf. These possible injuries make the anti-dumping on the vehicle There are certain research and development and application needs for devices and energy-absorbing devices for collapse. [0004] For the anti-dumping device ...

AI Technical Summary

Problems solved by technology

The traditional anti-tilting pedal assembly is mostly set on the pedal shaft, and is assembled with a split base. When an impact occurs, the pedal base is separated, and the pedal pin falls off along the main seat groove when the pedal base is separated, realizing The transmission route is interrupted. This kind of mechanism is relatively complicated, and the deformation of the seat sheet metal is unstable, which affects safety.
