Abstract

The invention provides a kind of automobile collision energy-absorbing box, comprising: an upper flange, a composite shell, an inner filler, a circular platform inner tube and a lower flange; the upper part of the composite shell is a square box, and each square box Five defect holes are arranged on the side along the diagonal; the lower part of the composite shell is a platform bellows, and its side edge is a sinusoidal corrugated structure; the circular platform inner tube is arranged in the composite shell, and the internal filler It is filled between the inner tube of the round table and the inner wall of the composite shell; the filling between the square box and the inner tube of the round table is a honeycomb structure, and the filling between the bellows of the table body and the inner tube of the round table is a lattice structure. The above-mentioned energy-absorbing box for automobiles has high energy-absorbing stability and good energy-absorbing effect.

Description

technical field [0001] The invention is a novel automobile collision energy-absorbing box device, which belongs to the field of automobile passive safety protection. Background technique [0002] With the continuous development of the automobile industry, automobiles have become an indispensable means of transportation for people's daily travel, but it is precisely because of the increase in the number of automobiles that traffic accidents occur frequently, causing huge human and financial losses. Therefore, automobile safety has become an important issue that we cannot ignore. The automobile energy absorbing box is an energy-absorbing device installed between the automobile beam and the frame longitudinal beam. It needs to absorb the impact energy and reduce the peak stress through its own collapse and deformation after the impact, so as to protect the automobile longitudinal beam and even the The cockpit is free from damage, reducing car maintenance costs and improving ca...
