Automobile anti-collision device

Abstract

The invention discloses an automobile anti-collision device. The automobile anti-collision device comprises a front anti-collision beam, a front buffer oil cylinder, an energy storage oil cylinder anda reset device, wherein the front anti-collision beam is arranged in front of a frame; the front buffer oil cylinder is fixedly connected with the frame, a piston rod of the front buffer oil cylinderis fixedly connected with the front anti-collision beam, and the front buffer oil cylinder comprises a first cavity and a second cavity; the energy storage oil cylinder comprises an energy storage cylinder fixedly connected with the frame, an energy storage piston slidably arranged inside the energy storage cylinder and an energy storage spring of which one end is connected with the energy storage piston, the energy storage oil cylinder comprises a third cavity and a fourth cavity, and the second cavity of the front buffer oil cylinder is communicated with the third cavity of the energy storage oil cylinder through a first one-way valve; and the reset device is used for enabling the piston rod of the front buffer oil cylinder to stretch out. Through the arrangement, great impact energy generated by automobile collision can be absorbed and stored by using energy conversion so as to achieve a buffer function for an automobile, the damage degree of the automobile is alleviated, and the life safety of passengers and drivers is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile anti-collision, in particular to an automobile anti-collision device. Background technique [0002] With the progress of society and the continuous improvement of people's living standards, automobiles have become an important means of transportation for people to travel, and the safety performance of automobiles is also more and more valued by users. In terms of safety performance, collision safety performance is one of the important contents of automobile structural design. In current automobile design, anti-collision beams installed at the front and rear of the automobile are usually used to ensure that the body structure frame will not be seriously damaged under collision. In order to absorb the kinetic energy of the collision as much as possible, a collision energy-absorbing box will be designed behind the anti-collision beam to absorb the kinetic energy of the collision by collapse and de...

AI Technical Summary

Problems solved by technology

In the prior art, the collision acceleration of the car body is relatively high, and the collision load is directly transmitted to the dash panel, resulting in a large amount of intrusion, but the energy-absorbing box installed at the rear end of the anti-collision beam cannot absorb the energy generated by the collision well
