An intelligent self-locking damper for preventing automobile throttle from being misstepped

Abstract

The invention discloses an intelligent self-locking damper for preventing the automobile throttle valve from being misstepped, and relates to the application of the technology for preventing the throttle valve from being misstepped in the automobile field. The intelligent self-locking damper consists of three parts: a throttle pedal linkage, a throttle anti-misstepped intelligent self-locking damper and a damping unlocking device. The throttle pedal linkage consists of a throttle pedal, a piston connecting rod and a return spring. The intelligent self-locking damper is composed of a damping piston, a damping spring, a misstepped self-locking cap, and a segmented block damping cylinder. The damping unlocker consists of unlocking keys, solenoid valves, pressure switches and connecting pipes.The self-locking throttle valve can not be pressed down when the initial state of the throttle valve is mistakenly pressed. Automatic release of self-locking function when driving at high speed in automobile; The damper unlocking button can be manually released from the mistread protection function according to the need. The device has the advantages of small volume, low cost, simple structure, practical and reliable, convenient installation, and is suitable for automobile throttle anti-stepping application.

Description

technical field [0001] The patent of the present invention relates to a safety device for anti-misstepping on the throttle valve and warning brake in the field of automobiles. Background technique [0002] The throttle of an ordinary car is controlled by the pedal through mechanical or electronic means to open the throttle valve plate. With the development of society, the popularization of automobiles and the large increase of amateur drivers, due to unskilled operation and panic, the situation of accidentally stepping on the throttle when stepping on the brakes occurs from time to time, and the traffic accidents caused by this are increasing year by year. Unnecessary loss to society and family. In recent years, automobile research and development departments at home and abroad and friends who love inventions have released a variety of designs and patents for anti-misstepping devices, but due to various problems and deficiencies, there is currently no effective solution wor...

Problems solved by technology

With the development of society, the popularization of automobiles and the large increase of amateur drivers, due to unskilled operation and panic, the situation of accidentally stepping on the throttle when stepping on the brakes occurs from time to time, and the traffic accidents caused by this are increasing year by year. Unnecessary loss to society and family

In recent years, domestic and foreign automobile research and development departments and friends who love inventions have released a variety of designs and patents for anti-misstepping devices. However, due to various problems and deficiencies, there is currently no effective solution worth promoting and implementing.

These problems and deficiencies can be roughly divided into three categories: 1. Change the traditional driving habits and change the throttle control from the foot pedal to the suspended suspension rod, so that the stability of the heel against the cockpit floor when the throttle pedal is stepped on is gone. , When the human body is swaying left and right when driving in complex road conditions, it is too unreliable to control the throttle boom by the movement of legs and feet; 2. Analyze the strength of stepping on the throttle pedal and the brake pedal from various sensors Different, the sensor signal is input into the microcomputer chip, and the servo motor drive circuit and the throttle control circuit are used to achieve the purpose of preventing misstepping. This kind of scheme requires the driving computer to cooperate with the modification of some circuits, which makes the electronic circuit of the car more complicated, and the reliability of the electronic circuit Can not be fully guaranteed; 3, the third category is purely mechanical similar to the principle of car seat belt retractor, this anti-misstepping device due to low sensitivity, insufficient reliability, limited the high-speed overtaking or climbing. Rapid acceleration performance, so it has not been recognized by the market
