Automobile anti-collision beam and energy-absorbing box thereof

Abstract

The invention discloses an anti-collision beam energy-absorbing box of an automobile. The energy absorbing box comprises a first box body and a second box body, wherein one end of the first box body is a first fixed end used for fixedly connecting with the anti-collision beam, and the other end of the first box body is a first abutting end used for butting with one end of the second box body; one end of the second box body is a second fixed end used for fixedly connecting with an automobile body, and the other end of the second box body is a second abutting end used for butting with one end of the first box body; a gap is formed between the first abutting end and the second abutting end, and the first abutting end and the second abutting end are arranged in a manner of alignment; the first abutting end and the second abutting end are disconnected in fact, so that the first box body and the second box body do not work in the first time when a collision occurs to an automobile, and protection for pedestrians can be facilitated, the first box body and the second box body come into contact with each other along with a constantly collision, then a degeneration energy absorbing function works, intrinsical functions of anti-collision and energy absorbing of the energy absorbing box are retained as well. The invention also discloses an anti-collision beam of an automobile, which adopts the anti-collision beam energy-absorbing box of the automobile.

Description

technical field [0001] The invention relates to the technical field of automobile anti-collision, in particular to an automobile anti-collision beam and an energy-absorbing box thereof. Background technique [0002] In today's society, the safety performance of automobile collisions has attracted much attention. The front anti-collision beam assembly is one of the main assemblies for energy absorption in collisions, and the energy-absorbing box in the anti-collision beam assembly absorbs the collision through its own crush deformation during the collision Energy is one of the important components of the anti-collision beam assembly. [0003] In the past, the energy-absorbing box structure of the anti-collision beam of automobiles was mostly a box-shaped structure with a polygonal cross-section. Two box-shaped structures with the same or symmetrical structure were distributed on both sides of the anti-collision beam. The box-shaped structure was welded to the anti-collision b...

AI Technical Summary

Problems solved by technology

The absorption of collision energy by the energy-absorbing box depends on its own collapse and deformation, and this kind of single energy-absorbing box can only control the collapse and deformation by designing its own energy-absorbing ribs, cross-sectional shape, etc., and the design has limitations

Moreover, there is no structural design for pedestrian protection
