Abstract

The invention discloses an automobile energy absorption box. The automobile energy absorption box comprises an energy absorption box body. The energy absorption box body is made of carbon fiber composite materials and is filled with foam aluminum alloy ingots. According to the automobile energy absorption box, as the energy absorption box body is made of the carbon fiber composite materials, the light weight effect is achieved; compared with a common metal energy absorption box, the weight of the energy absorption box which is filled with the foam aluminum alloy ingots and made of the carbon fiber composite materials is reduced by 25% to 40%, the absorbed energy is 1.5 times to 3 times that of the common metal energy absorption box, the collision energy absorption effect can be accordingly improved, and the light weight effect is achieved.

Description

Technical field [0001] The invention belongs to the technical field of automobile collision safety. Specifically, the invention relates to an automobile energy absorbing box. Background technique [0002] In order to avoid deformation of the front side member when a car is in a slight frontal collision, an energy-absorbing box is usually installed between the front cross member and the front side member of the car. When the impact energy of the collision exceeds the energy-absorbing capacity of the front bumper, the energy-absorbing box begins The crushing deformation can absorb part of the impact energy, thereby avoiding the impact energy directly acting on the front side member and causing its deformation. Currently, the commonly used energy-absorbing box structure has a pre-deformed design on its box body to improve its energy-absorbing deformation characteristics, but the energy-absorbing box made of sheet metal parts has a relatively high weight, resulting in low specific en...
