Magnetic buffering type anti-collision beam at front end of automobile

Abstract

The invention provides a magnetic buffering type anti-collision beam at the front end of an automobile. The anti-collision beam comprises a bow-shaped main beam the back surface of which are provided with connecting clamping bases symmetrically on the left side and the right side, with connecting rotating shafts being arranged in the middles of the connecting clamping bases; a horizontal fixing frame arranged on the rear side of the bow-shaped main beam in parallel; and a telescopic guide rod arranged on the rear side of the connecting clamping bases, a circular sliding block is arranged at the rear end of the telescopic guide rod, and a permanent magnet blocking ring is arranged in the middle of the circular sliding block in a surrounding mode. According to the anti-collision beam, the bow-shaped main beam serves as the collision main beam and is fixed to an automobile through the horizontal fixing frame, the bow-shaped main beam and the horizontal fixing frame are connected through the telescopic guide rod and a telescopic guide cylinder, and the bow-shaped main beam can move towards the rear side to enable the telescopic guide rod and the telescopic guide cylinder to slide relatively when collided, then thepermanent magnet blocking ring is driven to slide in a magnetic resistance inner copper tube, and the telescopic guide rod is hindered through electromagnetic resistance generated by a buffer spring and relative sliding of the buffer spring, so that buffering and energy absorption are carried out.

Description

technical field [0001] The present disclosure relates to the technical field of automobile anti-collision beams, in particular to an automobile front-end magnetic 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 anti...

Problems solved by technology

[0004] In view of this, the purpose of this disclosure is to propose a magnetic buffer type anti-collision beam at the front end of a car to solve the problem that after a collision, the main beam and the energy-absorbing box are easily deformed and damaged, especially in low-speed collisions, which often cause The main beam is deformed and needs to be replaced as a whole, the cost of use is high, and the buffering force of the collision is difficult to adjust flexibly
