Problems solved by technology

The existing bumper is mainly rigidly connected to the chassis. When a collision occurs, it can absorb a certain amount of energy, and a considerable part of it is transmitted to the body, resulting in damage to the body and casualties.
Although some bumpers also have an energy-absorbing effect, the effect is limited due to uneven energy absorption

Abstract

The invention discloses an energy-absorbing bumper. According to the energy-absorbing bumper, energy-absorbing elements and a telescoping mechanism are mounted between a front bumper beam and a rear bumper beam; each added energy-absorbing element comprises a damper and a spring to commonly enhance the energy-absorbing effect; the telescoping mechanism which can be shrunk elastically and uniformly is adopted to disperse collision energy on various damping and energy-absorbing elements so as to be uniformly absorbed by the bumper, nonuniform energy absorbing caused by centralized collision points is prevented, the buffering effect of the bumper is fully improved, and the energy-absorbing effect of the bumper is exerted to the maximal extent. Therefore, by adopting the novel bumper which can absorb collision energy in a telescoping manner, the effects of buffering and energy-absorbing of the bumper can be realized, and excessive impact caused by the rigid connection of the conventional bumper and a vehicle body is effectively avoided, so that collision energy transferred to the vehicle body and the human body is reduced, and the function of protecting the vehicle and passengers is realized.

Description

technical field [0001] The invention belongs to the field of automobile safety devices, in particular to an energy-absorbing bumper. Background technique [0002] The bumper belongs to the car safety auxiliary device and is installed at the front and rear of the car body. When a collision occurs, the bumper can protect the vehicle body and prevent the vehicle body from being directly impacted. For low-speed collisions, it can play a protective role by dispersing the impact force; for faster collisions, its energy absorption effect is limited, and its protective effect is also limited. The existing bumper is mainly rigidly connected on the chassis, and when a collision occurs, it can absorb a certain amount of energy, and a considerable part is transmitted to the vehicle body, thereby causing damage to the vehicle body and casualties. Although some bumpers also have an energy-absorbing effect, the effect is limited due to uneven energy absorption. Contents of the inventio...
