Abstract

The application discloses a bumper, a bumper assembly and a vehicle, wherein the bumper comprises a bumper body and a buffer reinforcement, a cavity is formed in the bumper body, the buffer reinforcement is arranged in the cavity, the bumper body comprises two first side walls which are oppositely arranged along a first direction and two second side walls which are oppositely arranged along a second direction, the first direction intersects with the second direction, the second side walls protrude towards the cavity to form a protruding part, and the buffer reinforcement is at least connected with the protruding part. Through setting up the buffering reinforcement in the bumper body, when the bumper receives great impact force or compression effect, two second lateral walls of bumper body can be to the cavity internal pressure crumple deformation in order to absorb impact energy, the buffering reinforcement in the bumper body cavity can produce the deformation effect opposite with two second lateral wall directions to hinder the further deformation of second lateral wall, thereby strengthen the rigidity of bumper body, improve the energy-absorbing effect of bumper, in order to reduce the injury to passenger and driver.
