Abstract

The invention discloses a car bumper with high safety. All branched bumper bodies are connected with a car body. A joint seal-connecting piece is arranged between the adjacent ends of every two branched bumper bodies and covers and seals the adjacent ends of the two branched bumper bodies. S-shaped damping and energy-absorbing plates are arranged on the inner side faces of arc-shaped sections at the two ends of a shell, a U-shaped energy-absorbing groove plate is arranged on the outer side face of the shell in the longitudinal direction, and a rubber energy-absorbing strip is arranged in the U-shaped energy-absorbing groove plate; and a plurality of rubber vertical columns which are arranged in a matrix mode are arranged on the front side and the rear side of the inner wall of a rubber airbag arranged in the U-shaped energy-absorbing groove plate. When local collision damage occurs to the car bumper, the bumper does not need to be overall replaced, the use and maintenance cost of a carare reduced, and the damping and energy-absorbing effects of the bumper can be reinforced, the rubber airbag can achieve the dual buffering effects, the damping and buffering effects are improved, and the anti-impacting performance of the car bumper is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile bumper equipment, in particular to an automobile bumper with high safety. Background technique [0002] The bumper is a safety device that absorbs and moderates external impact and protects the front and rear of the car body. With the development of the automobile industry, the automobile bumper, as an important safety device, is also on the road of innovation. The original automobile bumper includes: a bumper body, which is directly composed of an inner layer fixing bracket and an outer layer blocking When the car bumper has a relatively large collision, the impact resistance is weak and the cushioning effect is poor. When the car bumper is slightly scratched, it is easy to be scratched. After the scratch, it needs to be painted or even replaced, which is a waste of time. Time increases the financial burden. The car bumper is an important vulnerable part of the car, especially the left and r...
