Front safety girder and rear safety girder capable of realizing rigidity and flexibility combined efficient buffering energy absorption

Abstract

The present invention replaces the front and rear anti-collision beams with the front and rear safety beams combining rigidity and flexibility with high-efficiency cushioning and energy absorption on the basis of theoretically calculating the energy absorption and under the condition of keeping the structure, shape, appearance and function of the automobile body unchanged. A new generation of automotive passive safety devices. It utilizes the positions and cavities of the front and rear anti-collision beams installed in existing automobiles, and installs safety beams on the two ends of the front and rear longitudinal beams of the automobile. The energy absorber and the bottom beam are composed of the bottom beam as the rigid force-bearing part, and the cover and the energy absorber are the flexible energy-absorbing parts, which have the structural characteristics of rigid-flexible combination and can solve the original anti-collision beam with little effect in high-speed and medium-speed collisions. Problems, greatly improve the impact resistance of the car, and protect the personal safety of the occupants to the greatest extent. It has been verified by implementation cases that compared with the existing anti-collision beams of automobiles, it is superior to the original anti-collision beams in terms of safety, technology, and economy. Replacing the anti-collision beams with safety beams with significant energy-absorbing effects will inevitably become the first choice for automobiles. The direction of security technology development.

Description

technical field [0001] The invention relates to automobile safety in the technical field of traffic safety, in particular to an energy-absorbing energy-absorbing device that combines rigidity and flexibility with high-efficiency energy absorption under the condition of keeping the structure, shape, appearance and function of the automobile body unchanged on the basis of theoretical calculation of energy absorption. A new generation of automotive passive safety devices that replace the front and rear anti-collision beams. Background technique [0002] At present, the most advanced vehicle active safety technology in the world is the intelligent automatic driving device.
