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.
