Automobile front end hydraulic buffer type anti-collision beam

Abstract

The invention provides an automobile front end hydraulic buffer type anti-collision beam which comprises a bow-shaped main beam, an arc-shaped collision plate is arranged on the front face of the bow-shaped main beam, a hollow communication groove is formed penetrating the center of the bow-shaped main beam, a fixing back plate is arranged on the back face of the bow-shaped main beam, and a plurality of reserved grooves are evenly formed in the middle of the bow-shaped main beam at intervals. And connecting clamping seats are symmetrically arranged at the left end and the right end of the fixing back plate. The bow-shaped main beam serves as a collision main beam and is connected and fixed through a horizontal fixing frame, the bow-shaped main beam and the horizontal fixing frame are connected through the positioning sleeve, a center guide rod and a hourglass energy absorption box, the bow-shaped main beam can conveniently move towards the rear side when collision occurs, and kinetic energy is absorbed through collapse of the hourglass energy absorption box; and the positioning sleeve and the center guide rod are fixed to the bow-shaped main beam and the horizontal fixing frame through the embedded connection structures correspondingly, so that the positioning sleeve and the center guide rod can be disassembled and assembled rapidly, and then the anti-collision beam can be maintained conveniently.

Description

technical field [0001] The present disclosure relates to the technical field of automobile anti-collision beams, in particular to an automobile front-end hydraulic buffer type anti-collision beam. Background technique [0002] The car 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 a main beam, an energy-absorbing box, and a mounting plate connected to the car. The energy-absorbing box is then connected to the longitudinal beam of the vehicle body in the form of bolts. Both the main beam and the energy-absorbing box can effectively absorb the collision energy when the vehicle collides at a low speed, and minimize the damage of the impact force to the longitudinal beam of the vehicle body. It can protect the vehicle, and the anti-collision beam structure should ensure that the low-speed energy-absorbing box can effectively absorb the energy of low-speed impact through collapse. The ant...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the purpose of this disclosure is to propose a hydraulic buffer type anti-collision beam at the front end of the automobile to solve the problem that after the collision of the vehicle, the main beam and the energy-absorbing box are easily deformed and damaged, especially in low-speed collisions. The main beam is deformed, and it needs to be replaced as a whole, the cost of use is high, and the maximum energy absorption of the overall structure is low.
