Device for switching false urgent accelerator operation into emergency braking during emergency state of vehicle

Abstract

A device for switching false urgent accelerator operation into emergency braking during the emergency state of a vehicle comprises a retractor, a retractable belt-retracting spring and pawls, the retractor is connected with a braking system, a retractable belt of the retractor is connected with an accelerator cable, the principle of the retractable is similar to the principle of an automotive safety belt, the retractable belt-retracting spring is mounted on one side of the retractable belt in the retractor, the pawls are mounted on the other side of the retractable belt, and the pulling speedof the retractable belt controls the centrifugal force of the pawls and adjusts the centrifugal positions of pawl teeth, so that the retractable belt can be freely pulled or stuck and can drive the braking system to carry out braking. The device is characterized in that: the retractor is mounted in a rectangular cavity-shaped emergency brake box, and is normally located at one end in the emergency brake box, which is close to a connecting cable of the braking system, and when the accelerator-stepping speed is over-high, the retractable belt is stuck to pull the retractor and drive a braking cable, so that the braking system is pulled to carry out braking.

Description

technical field [0001] The invention relates to an emergency braking device which is converted by mistakenly stepping on the accelerator when a motor vehicle is in an emergency state, is applicable to various motor vehicles, and belongs to the technical field of automobile safety and braking. Background technique [0002] We often hear reports: When a driver encounters an emergency, he should have slammed on the brakes but accidentally stepped on the accelerator, causing a bigger accident, because the reaction time of the human brain is about 0.1 seconds, and it is judged in this extremely short time And send instructions to hands and feet to take relevant actions. Once you judge or give instructions to hands and feet or take related actions and step on the accelerator by mistake, the result will greatly increase the severity of the accident consequences; Stepping on the gas pedal in a hurry is converted into an emergency brake, which can greatly restore the serious consequ...

[0002] We often hear reports: When a driver encounters an emergency, he should have slammed on the brakes but accidentally stepped on the accelerator, causing a bigger accident, because the reaction time of the human brain is about 0.1 seconds, and it is judged in this extremely short time And send instructions to hands and feet to take relevant actions. Once you judge or give instructions to hands and feet or take related actions and step on the accelerator by mistake, the result will greatly increase the severity of the accident consequences; Stepping on the gas pedal in a hurry is converted into an emergency brake, which can greatly restore the serious consequences caused by stepping on the gas pedal in a wrong way, but when searching for relevant patent documents, no relevant content is found, and no relevant research results and Applications
