Automobile anti-collision cross beam with good energy absorption effect

Abstract

The invention provides an automobile anti-collision cross beam with the good energy absorption effect. The cross beam comprises a front beam structure, a first-stage energy absorption structure, a transverse column, a second-stage energy absorption structure, a third-stage energy absorption structure and a cross beam set, the first-stage energy absorption structure capable of buffering impact force in different directions is fixedly installed on the lower surface of the front beam structure, the transverse column is arranged below the first-stage energy absorption structure, the second-stage energy absorption structure capable of buffering impact force from the first-stage energy absorption structure to a certain degree is arranged in the transverse column, the second-stage energy absorption structure is elastically connected with the first-stage energy absorption structure, the third-stage energy absorption structure capable of buffering impact force from the second-stage energy absorption structure is fixedly installed on the lower surface of the transverse column, and the cross beam set is fixedly mounted on the lower surface of the third-stage energy absorption structure. The front beam structure, the first-stage energy absorption structure, the second-stage energy absorption structure and the third-stage energy absorption structure match one another, accordingly, high-benefit graded buffering effects can be realized, excellent energy absorption effects can be realized, and the integral cross beam set can be assuredly prevented from being deformed and damaged due to excessively high impact force.

Description

technical field [0001] The invention relates to the technical field of automobile anti-collision beams, in particular to an automobile anti-collision beam with good energy absorption effect. Background technique [0002] Automobile anti-collision beams are an important part of the body structure. They are generally installed on the front and rear bumpers, side doors, etc. of vehicles, which can directly protect the safety of drivers and passengers in collisions. Made of high-safety steel plates, when the collision force is applied, it will be transmitted to the frame of the vehicle to bear it. [0003] Generally, the first anti-collision beam of a car is an anti-collision steel beam, which is connected to the whole frame of the car through an energy-absorbing box. If it is passed to the beam, it cannot be buffered in stages, and the damage to the entire frame of the car body is relatively large, and the repair work in the later stage is difficult. [0004] Therefore, we pr...
