Protection device for accelerator mistaken stepping in car emergency braking

Abstract

The invention provides a protection device for accelerator mistaken stepping in car emergency braking. The device is characterized in that the device comprises a braking foot bar, an accelerator foot bar, a locking mechanism and a mounting seat; the braking foot bar and the accelerator foot bar are mounted on a left ear base and a right ear base of the two ends of the mounting seat through a circular column of the left end of an outer ring and a core shaft correspondingly and axially fixed through flat keys; the locking mechanism comprises the outer ring and a star wheel, the star wheel is mounted in the outer ring, and a baffle is mounted at the right end of the star wheel; wedge-shaped grooves are formed in the star wheel, friction rollers are mounted in the wedge-shaped grooves and pressed at the larger-diameter ends of the wedge-shaped grooves through sensitive springs; and the star wheel and the core shaft are connected through a spline, block columns are arranged on the baffle and the mounting seat to enable a volute spiral spring mounted between the block columns to have compressed elastic potential energy, and the mounting seat is fixed to the corresponding position which a right foot in a vehicle can reach through a bolt set. According to the device, accelerator mistaken stepping can be effectively judged, and rapid response is achieved; and the device is simple in structure, safe and reliable. When danger is removed, automatic resetting of the protection device can be achieved only by loosening the foot.

Description

Technical field [0001] The invention belongs to the technical field of automobile parts and components, and particularly relates to a mechanical emergency protection device, in particular to a protection device for accidentally stepping on an accelerator pedal during emergency braking of an automobile. Background technique [0002] In recent years, with the rapid economic development, private cars have rapidly become popular in large, medium and small cities in China, and the number has increased sharply. The accelerator and brake of the car are controlled by the right foot, and the distance is relatively short. Many drivers with low driving age are likely to use the accelerator as a brake by mistake due to various improper operations or emergency accidents. According to statistics, a considerable part of automobile traffic accidents in China are caused by accidental acceleration caused by accidentally stepping on the accelerator during emergency braking, which brings great hidde...

AI Technical Summary

Problems solved by technology

The accelerator and brake of the car are controlled by the right foot, and the distance is relatively short. When many drivers with low driving experience are driving a car, due to various improper operations or emergency situations, it is easy to use the accelerator as a brake by mistake.

According to statistics, a considerable number of automobile traffic accidents in China are basically caused by false acceleration caused by emergency braking and accidental stepping on the accelerator, which brings great hidden dangers to people's travel safety.

[0003] Although the automobile industry is developing rapidly, and more and more safety devices have become the standard configuration of the automobile industry, the problem of accidentally stepping on the accelerator has not been fundamentally resolved for a long time

In order to prevent such traffic accidents, it is necessary to develop a device or system for preventing accidental stepping on the brakes and accelerators. However, many anti-misstepping devices and related patents are mostly complex in design, and use electronic systems such as pressure sensors and speed sensors.

Due to the complex driving conditions of the car, there are many electronic components and circuits in the car, which can easily cause interference to it, resulting in dangerous situations such as emergency brake failure or even mutual interference of accelerator and brake.
