Embodiment Construction

[0034] In order to describe in detail the technical content, structural features, achieved objectives and effects of the technical solution, the following detailed description will be given in conjunction with specific embodiments and accompanying drawings.

[0035] See figure 2 This embodiment provides an automobile energy absorbing device, which is arranged on the front and rear of the automobile to absorb the impact force generated when the automobile collides. Specifically, the automobile energy absorbing device is arranged on the automobile Between the longitudinal beam of the frame and the protective bar, the energy absorbing device is used to improve the passive safety of the automobile or the frame, thereby avoiding or reducing the main structure of the automobile frame and the passengers in the vehicle from being injured. Among them, the frame is the most important load-bearing component in the car, and the frame longitudinal beam is one of the key parts, so the longitud...

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 the kinetic energy of automobile collision. Background technique [0002] With the popularization of automobiles, the safety requirements for automobile driving are becoming more and more stringent. In order to improve the driving safety of automobiles, the safety of passengers and pedestrians is mainly protected through active safety measures and passive safety measures. Active safety measures include the body stabilization system and pre-collision automatic braking system of the current mainstream cars; passive safety measures include car airbags and car energy-absorbing boxes. 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 to reduce occupant injuries after a traffic accident. Among them, the safety of a frontal collision of the car is par...
