Problems solved by technology

The traditional energy-absorbing box is composed of steel sheet metal parts. This kind of energy-absorbing box is heavy. In recent years, most of the energy-absorbing boxes developed are made of aluminum alloy. However, due to its simple extrusion structure, its crushing characteristics, Energy absorption capacity and crash stability are also not high

Abstract

The invention provides an efficient buffer energy absorption device for automobiles. The efficient buffer energy absorption device comprises a first connecting plate, a second connecting plate and a shell body, wherein the first connecting plate and the second connecting plate are arranged at the two ends of the shell body respectively, a porous aluminum alloy section and a hard rubber section arefilled in the shell body, a group of large hole transverse grooves and a group of small hole transverse grooves are formed in the porous aluminum alloy section, and the large hole transverse groovesand the small hole transverse grooves are sequentially arranged at intervals. The distances between every two adjacent large hole transverse grooves are equal, the distances between every two adjacentsmall hole transverse grooves are equal, and it is ensured that when the efficient buffer energy absorption device is stressed, all the parts are stressed uniformly.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile high-efficiency buffer energy-absorbing device. Background technique [0002] With the increasing number of automobiles and the increasing number of automobile safety accidents, people pay more and more attention to the collision safety performance of automobiles. As an important part of the passive safety of automobiles, the energy-absorbing box absorbs the kinetic energy of the collision and reduces the maximum impact force through the compression deformation of the energy-absorbing box when a collision accident occurs, so as to alleviate the impact and reduce the damage to the car body and the injury of personnel caused by the collision accident. . The traditional energy-absorbing box is composed of steel sheet metal parts. This kind of energy-absorbing box is heavy. In recent years, most of the energy-absorbing boxes developed are made of aluminum allo...
