Abstract

The invention relates to the field of automobile safety, and discloses an automobile energy absorption device. The energy absorption device comprises a first fixed plate, a second fixed plate and an energy absorption component; the energy absorption component is a three-dimensional spiral wire-shaped plastic material; the first fixed plate is arranged at one end of the plastic material, and the second fixed plate is arranged at the other end of the plastic material; the automobile energy absorption device is arranged between a vertical beam of an automobile and a protection lever, the first fixed plate is connected to the vertical beam, and the second fixed plate is connected to the protection lever. According to the technical scheme, the three-dimensional spiral wire-shaped plastic material is adopted in the energy absorption component, and the fixed plates are arranged at the two ends of the energy absorption component. The lateral shock resistance capability of the energy absorption component is improved, the lateral crumple is not likely to occur, each area of the energy absorption component in the axial direction has the same conquassation limit, so that when the energy absorption component is under shock, uniform and regular crumple can be achieved, and the energy absorption effect of the energy absorption component is sharply improved.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to an automobile energy absorbing device for absorbing collision kinetic energy of automobiles. Background technique [0002] With the popularity of automobiles, the safety requirements of automobile driving are becoming more and more stringent. In order to improve the driving safety of automobiles, it is mainly to protect the safety of passengers and pedestrians through active safety measures and passive safety measures. Active safety measures include body stabilization systems, pre-collision automatic braking systems, etc. that are configured in current mainstream vehicles; passive safety measures include automotive airbags, automotive energy-absorbing boxes, etc. The passive safety of a car is an important measure of the safety level of a car. Passive safety refers to the performance of the car itself in mitigating occupant injuries after a traffic accident. Among them, the safet...
