Abstract

The invention provides an automobile collision energy absorbing box. The automobile collision energy absorbing box comprises an upper flange plate, a compound shell, internal filling, a cone-frustum inner tube and a lower flange plate; the upper portion of the compound shell is a square box, and five defect holes are formed in each side face of the square box along the diagonal line; the lower portion of the compound shell is a table body corrugated pipe, and the lateral edges of the compound shell are of sinusoidal corrugation structures; the cone frustum inner tube is arranged in the compound shell, and the space between the cone frustum inner tube and the compound shell is filled with the internal filling, wherein the filling between the square box and the cone frustum inner tube is ofa honeycomb structure, and the filling between the table body corrugated pipe and the cone frustum inner tube is of a lattice structure. The automobile energy absorbing box is high in energy absorbingstability and good in 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...
