Problems solved by technology

This type of automobile bumper has only one beam. Even if a collision energy-absorbing box is added, the impact force it can withstand is still relatively small. Moreover, the force-bearing surface of a single beam is small, and it can only play a better role in anti-corrosion when the impact direction is facing the beam. When the impact direction deviates from the beam, the anti-collision performance will be greatly reduced; in addition, the connection mode between the internal structures of this type of automobile bumper is mainly integrally formed or fixedly connected, and different degrees of impact are all borne by the bumper as a whole, even if it is Slight collisions can also easily lead to damage to crash-absorbing boxes, beams and other components, resulting in short service life and high maintenance costs

Abstract

The invention discloses an automobile safety mechanism. The mechanism comprises an automobile front bumper and an automobile body which is matched with the automobile front bumper. The automobile bodycomprises a longitudinal beam which is arranged at the front end of the automobile body. The automobile front bumper comprises a shell and a reinforcement device which are elastically connected withthe longitudinal beam. The reinforcement device comprises an anti-collision mechanism which is fixedly connected with or integrally formed on the longitudinal beam, a first reinforcement mechanism which is elastically connected with the longitudinal beam and a second reinforcement mechanism which is elastically connected with the longitudinal beam. The maximum limit of elastic compression of the elastic junction between the first reinforcement mechanism and the longitudinal beam is that the elastic junction is compressed till the shell abuts against the first reinforcement mechanism and the anti-collision mechanism at the same time. The maximum limit of elastic compression of the elastic junction between the second reinforcement mechanism and the longitudinal beam is that the elastic junction is compressed till the shell abuts against the second reinforcement mechanism and the anti-collision mechanism at the same time. Multiple components are arranged, the mechanism bears collision ofdifferent degrees in a grading mode, the safety performance of the automobile front bumper is greatly improved, the maintenance cost is greatly reduced at the same time, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an auto safety mechanism. Background technique [0002] With the development of society, the use of cars in daily life is becoming more and more common. But along with the extensive use of automobile, traffic accident also often takes place. Therefore, people pay more and more attention to the safety performance of automobiles. Car safety mechanisms, especially the front bumper, are crucial to improving the safety performance of the car. [0003] The current automobile front bumper, such as the Chinese invention patent with the patent number ZL200510022817. Collision absorbing box cushioning. This type of automobile bumper has only one beam. Even if a collision energy-absorbing box is added, the impact force it can withstand is still relatively small. Moreover, the force-bearing surface of a single beam is small, and it can only play a better role in anti-corrosion when the impact d...
