Repeatedly usable self-locking energy-absorbing automobile bumper

Abstract

The invention discloses a repeatedly usable self-locking energy-absorbing automobile bumper, which comprises two parallel bumpers and a plurality of self-locking energy-absorbing spring components. The two ends of each self-locking energy-absorbing spring component are fixed between the two parallel bumpers through universal joint connection. In the bumper structure provided by the invention, the motion of the compression springs is limited in a sleeve to prevent the springs from torsion due to stress and from becoming invalid; therefore, when an automobile come into incidental collision, the springs can move in preset tracks to effectively absorb energy in the collision of the automobile.

Description

technical field [0001] The invention relates to a self-locking energy-absorbing automobile bumper, in particular to a reusable self-locking energy-absorbing automobile bumper. Background technique [0002] At present, the car bumper adopts a curved beam structure and is installed in front of the car to protect the engine from damage. This kind of bumper will generate a huge impact force when the vehicle collides, resulting in serious deformation of the bumper. In view of this situation, There is a patent document that adopts a clip-type semi-spring structure to design a new type of automobile bumper. For details, refer to the patent document CN102019892A. damage, but the spring of this structure is in a semi-free state, that is, after the accidental collision of the car, the spring is compressed and there is no stable structure to fix the spring in the compressed state, and the bumper of this structure may rebound Moreover, the spring of this structure is in an exposed st...

[0002] At present, the car bumper adopts a curved beam structure and is installed in front of the car to protect the engine from damage. This kind of bumper will generate a huge impact force when the vehicle collides, resulting in serious deformation of the bumper. In view of this situation, There is a patent document that adopts a clip-type semi-spring structure to design a new type of automobile bumper. For details, refer to the patent document CN102019892A. damage, but the spring of this structure is in a semi-free state, that is, after the accidental collision of the car, the spring is compressed and there is no stable structure to fix the spring in the compressed state, and the bumper of this structure may rebound Moreover, the spring of this structure is in an exposed state. When the force on both ends of the spring is not on the same center line, the spring will be twisted and deformed, thus affecting the energy absorption effect of the spring.
