Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] As shown in the figure, the automobile bumper device of this embodiment includes a bumper shell 1, and also includes several damping springs 3 between the bumper shell 1 and the frame beam 2 and are fixed on the frame beam 2 in parallel. The spring holder 4, the shock-absorbing spring cover 3 is on the spring holder 4; the bumper shell 1 is connected with the frame beam 2 through an energy-absorbing box, and the energy-absorbing box includes a regular hexagonal shell 5 and An X-shaped cross plate 6 arranged in a regular hexagonal shell;

[0026] The outer surface of the bumper shell 1 is longitudinally provided with a U-shaped energy-absorbing groove plate 7, and a rubber energy-absorbing strip 8 is arranged inside the U-shaped energy-absorbing groove plate 7, and the U-shaped energy-absorbing groove plate 7 and The bumper shells 1 are connected...

Abstract

The invention discloses an automobile bumper device which comprises a bumper shell, a damping spring and a spring fixing seat. The bumper shell is connected with a frame beam through an energy absorption box. A U-shaped energy absorption groove plate is longitudinally arranged on the outer side face of the bumper shell. A rubber energy absorption strip is arranged in the U-shaped energy absorption groove plate which is connected with the bumper shell through bolts. By means of the U-shaped energy absorption groove plate and the rubber energy absorption strip, the damping and energy absorption effects of a bumper can be enhanced, the passive collision protection capacity of the bumper is improved, the buffering and damping protection effects can be achieved through deformation of the U-shaped energy absorption groove plate and the rubber energy absorption strip during slight collision, the bumper shell can be prevented from deformation and damage, the U-shaped energy absorption groove plate can be detached and maintained, and the maintenance cost is low; meanwhile, the automobile bumper device comprises multi-stage composite damping parts such as the U-shaped energy absorption groove plate, the bumper shell and the energy absorption box, the damping and energy absorption capacity is high, and the life safety of personnel in an automobile can be better protected.

Description

technical field [0001] The invention relates to an automobile component, in particular to an automobile bumper device. Background technique [0002] The existing automobile bumper device is generally an arc-shaped shell structure made of steel plate stamping. During the collision process, the deformation of the bumper absorbs the collision energy, and its buffering and shock absorption function protects the life safety of the people in the car. [0003] But because the existing automobile bumper device absorbs and consumes the collision energy only by the deformation of the housing, its buffering and energy-absorbing effect is not good enough, and its protection ability to the occupants and the vehicle itself needs to be improved. [0004] Moreover, the existing automobile bumper device has an integral structure. When the bumper is partially collided and deformed, it needs to be replaced as a whole, and the maintenance cost is relatively high. [0005] Simultaneously existi...
