Automobile anti-collision beam

Abstract

The invention belongs to the technical field of automobile accessories, and particularly relates to an automobile anti-collision beam which comprises a main beam, an energy absorption component and a frame connecting piece. The side wall of the energy absorption component is arranged to be of a corrugated structure, so that when a vehicle collides with the energy absorption component and is subjected to front impact, impact force parallel to the axial direction of the energy absorption component cannot be kept parallel to the side wall of the energy absorption component, force borne by the face, not parallel to the axis, of the side wall of the energy absorption component and the face form a certain included angle, force borne by the side wall of the energy absorption component has component force in the direction perpendicular to the side wall, then the local side wall bears radial force, the energy absorption component can easily and evenly deform, and in the whole process, the energy absorption component always absorbs impact energy through deformation till the maximum deformation amount is achieved. Therefore, it is guaranteed that the energy absorption component can stably and reliably absorb impact energy, impact on a driver is reduced, and the safety of the driver and passengers is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to an anti-collision beam for an automobile. Background technique [0002] The anti-collision beam is a device used to reduce the absorption of collision energy when the vehicle is hit by a collision. It is composed of the main beam, the energy-absorbing box, and the mounting plate connected to the car. The main beam and the energy-absorbing box can effectively absorb when the vehicle collides at a low speed. Collision energy, to minimize the damage of the impact force to the longitudinal beam of the vehicle body, through which it can play its protective role on the vehicle; the structure of the anti-collision beam should ensure that the low-speed energy-absorbing box can effectively absorb the energy of low-speed impact through collapse , The anti-collision beam is connected to the body by bolts, which is convenient for disassembly and replacement. Now a layer of foam buffer is...

AI Technical Summary

Problems solved by technology

The invention is mainly used to solve the problem that when the traditional anti-collision beam is subjected to a frontal impact, the energy-absorbing box is not easy to deform and cannot absorb the impact energy, and then the impact energy is transmitted to the vehicle body to cause damage to the driver and passengers
