Elastic collision buffer for automobile

Abstract

The elastic collision buffer for automobile includes a piston fixed to the bumper and a hydraulic cylinder fixed to the automobile frame, and features that the hydraulic cylinder is one high pressure oil cylinder with oil cavity filled with hydraulic oil, and the oil cavity may be connected through high pressure oil pipe pressure accumulating cylinder filled with hydraulic oil to form one closed hydraulic system. By means of the closed hydraulic system structure, the high pressure oil cylinder is designed as one true great force í‹springíŒ and can convert most of the kinetic energy collision produces into the elastic potential energy of the hydraulic oil while converting the rest energy into heat. The entire damping process has prolonged í‹springíŒ deformation period, increased impulse action time and effectively reduced impact force. The elastic collision buffer can protect rider in side the automobile and the automobile from collision effectively.

Description

technical field

[0001] The invention relates to a collision buffer, in particular to a collision elastic buffer applied to a car to prevent the car from being damaged at the moment of collision. Background technique

[0002] At present, automobiles have already become a closely related means of transportation in people's lives because of their convenience and speed. But the tragedies of car crashes and fatalities caused by the accompanying traffic accidents also occur from time to time. And from the analysis of various accidents, it can be seen that the collision loss of the front and rear ends of the car is the most serious. In order to protect the safety of the occupants in the car as much as possible, the traditional design of the front and rear ends of the car follows the principle of "it is better to destroy the car than to die". At the same time, a bumper is also designed at the front and rear of the car, which is rigidly connected with the car body. When the car su...
