Automobile collision buffer protector

Abstract

The invention relates to a car collision security protection equipment. It provides a car collision protection equipment, it includes the bumper, the buffer spring, the hydraulic pressure telescopic pole, the consuming gasoline tank and the vitta and electromagnetism controlling check valve and so on, it is connected to the brake release energy port and replacement balance port of the two hydraulic pressure telescopic poles through the balance equipment, the electromagnetism controlling check valve is joining up inseries in each replacement vitta (attached drawing ), the buffer spring is vary distance column helix spring. The invention solve the problem of current car collision buffer protection can not be improved with the improvement of the car speed, can not brake and close the accelerograph in time when the collision occurred , rolling because of the imbalance of strained, and the problem because of the spring of bumper to produce the second time collision and the self comeback problem. The invention can improve the car buffer protection speed to 80kilometer / hour, it has a simple structure, and is suitable to be fixed on the car head and car tail of all kinds of automobile.

Description

technical field [0001] The invention relates to an automobile collision safety protection device. Background technique [0002] At present, the collision safety protection devices used in automobiles produced in the world include: bumpers, passive energy-absorbing engine rooms (front engines), safety airbags and safety belts; Slight protective effect; in the event of a frontal collision, the airbag can only protect the head of the human body, the seat belt fixes the person on the seat, and can only prevent the human body from flying out of the car, and the passive energy-absorbing engine room can only passively absorb Yes, it cannot be recovered (destroyed) after a collision, as long as a larger collision occurs, the car will be destroyed. Now the best car, personal safety collision design speed is 50 km / h; with the increasing improvement of the expressway network, more and more time for high-speed driving, chain collision accidents on the expressway in foggy days occur fro...

AI Technical Summary

Problems solved by technology

Now there are PLZIV type vehicle energy-absorbing and energy-releasing buffer devices, three-stage buffer devices for patting cars and oil cylinder type buffer protection devices; The problem that the effect cannot be improved with the increase of the speed of the vehicle, the problem that the brakes and the accelerator cannot be closed in time when a collision occurs, the problem that the vehicle rolls over due to unbalanced forces during a collision, and the rebound of the bumper when the collision stops causes a secondary collision. Problems and problems with self-healing deformations
