Press-fitting type energy absorption box assembly and vehicle

Abstract

The invention discloses a press-fitting type energy absorption box assembly and vehicle. The press-fitting type energy absorption box assembly comprises an energy absorption box body, wherein the energy absorption box body is an aluminum alloy extrusion forming part, the rear end of the energy absorption box body is arranged in the front end of a front longitudinal beam in an interference fit mode in the left-right direction, and the energy absorption box body and the front end of the front longitudinal beam are fixed through a connecting bolt. The press-fitting type energy absorption box assembly is good in energy absorption effect and simple in structure, problems of poor connection or vibration abnormal sound and the like between the energy absorption box body and the front longitudinal beam can be effectively avoided, meanwhile, a problem of longitudinal beam limiting is avoided, universality is good, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a press-fitted energy-absorbing box assembly and a vehicle. Background technique [0002] The front and rear energy-absorbing boxes of the car can effectively absorb the collision energy during the collision process, and minimize the damage to the car body longitudinal beam by the impact force, which can not only improve the passive safety of the car body, but also reduce the maintenance cost. [0003] At present, with the adoption of higher collision standards in the automobile industry and the requirements of lightweight goals and reduction of maintenance costs caused by collisions, the crash box, as a component to improve the safety of automobiles in collision accidents, has become the development of the automobile industry. It is one of the important research tasks in realizing the target requirements such as crash performance. Generally speaking, the materi...

AI Technical Summary

Problems solved by technology

Generally speaking, the materials of energy-absorbing boxes commonly used in the automotive industry are steel or aluminum, and the way to install them on the longitudinal beams is end-plate type or plug-in type. From the perspective of materials, energy-absorbing boxes made of steel materials are the most developed in the industry. It is relatively mature, and the energy-absorbing box made of steel is generally installed in the end-plate type. The disadvantage is that it can only absorb the collision by breaking and deforming, which requires a large energy-absorbing area. The installation method of the aluminum energy-absorbing box is generally end-plate or inserting It can be used in any form, and has a certain lightweight effect. It can absorb the collision energy in the form of crushing, which can reduce the space of the energy-absorbing area, but it brings huge challenges to the flanging welding process and installation method of aluminum materials.
