Automobile energy absorption box

Abstract

The invention discloses an automobile energy absorption box. The automobile energy absorption box comprises an energy absorption box body; the section of the energy absorption box body is quadrilateral; a plurality of grooves are formed in the surface of the energy absorption box body; all the grooves are formed in the radial direction of the energy absorption box body; through holes are formed inthe positions, located in the grooves, of the energy absorption box body; a first connecting plate is arranged at one end of the energy absorption box body, and a second connecting plate is arrangedat the other end of the energy absorption box body; and reinforcing plates are arranged at the joint of the first connecting plate and the energy absorption box body and the joint of the second connecting plate and the energy absorption box body. According to the energy absorption box, the specific energy absorption rate of unit mass is very high, collision at low and medium collision speeds can be well coped with, and the maintenance and replacement cost is very low.

Description

technical field [0001] The invention relates to the technical field of automobile energy-absorbing boxes, in particular to an automobile energy-absorbing box. Background technique [0002] The energy-absorbing box is behind the front bumper. If there is a frontal collision accident, the energy-absorbing box will play a very important role in absorbing a large amount of impact energy and protecting the safety of the driver. my country's total automobile production is huge. And this is accompanied by the increase in traffic accidents, and many people lose their lives every year, so safety has become particularly important, which means that traffic safety has become a part of public safety. 67% of automobile accidents are frontal collisions, 28% are side collisions, and the ratios of rear-end collisions and rollovers are low. The energy-absorbing box in the bumper is the main device to absorb the energy of the collision accident. With the increasing requirements for automobi...

AI Technical Summary

Problems solved by technology

[0003] Traditional energy-absorbing boxes use steel, aluminum alloy and other materials, which have high density and high mass, and the structure is generally a single-layer thin-walled cylinder. Collisions at medium collision speeds are powerless, and the maintenance and replacement costs are relatively high. Therefore, an improved technology is urgently needed to solve this problem in the prior art
