Abstract

The invention discloses a vehicle bumper. The vehicle bumper comprises a first crossbeam, a second crossbeam and a third crossbeam; the third crossbeam comprises a first buffer bar and a second bufferbar which are symmetrically distributed, a connecting rack is arranged between the first buffer bar and the second buffer bar, grooves conforming to the first buffer bar and the second buffer bar areformed in the two sides of the connecting rack respectively, the first buffer bar and the second buffer bar are inserted into the grooves and fixedly connected with the connecting rack through the grooves, a first connecting rod is arranged between the first crossbeam and the first buffer bar, a second connecting rod is arranged between the first crossbeam and the second buffer bar, and the firstconnecting rod and the second connecting rod penetrate through the second crossbeam, and are located at the tail ends of the first buffer bar and the second buffer bar respectively. The vehicle bumper can effectively achieve damping and energy dissipation.

Description

technical field [0001] The invention relates to an automobile bumper. Background technique [0002] The front and rear ends of the car are equipped with bumpers, which not only have decorative functions, but more importantly, are safety devices that absorb and ease external impact, protect the body and protect the occupants. [0003] With the development of the automobile industry and the extensive application of engineering plastics in the automobile industry, automobile bumpers, as an important safety device, are also on the road of innovation. At present, in addition to maintaining the original protective function, the front and rear bumpers of automobiles also need to pursue harmony and unity with the shape of the car body, and pursue their own lightweight. The front and rear bumpers of cars are made of plastic, which are called plastic bumpers. [0004] However, the existing automobile bumper cannot effectively dissipate energy when an accidental collision occurs. bu...
