Bumper with buffering structure

Abstract

The invention relates to a bumper with a buffering structure. The bumper comprises a transverse beam, buffer plates, elastic bodies and connecting seats, wherein the transverse beam is arranged along the width direction of an automobile; energy absorbing boxes are arranged on the two end parts of the transverse beam along the longitudinal direction of the automobile; the two ends of the buffer plates extend along the width direction of the automobile; the buffer plates are fixed on the surface, which faces an automobile body, of the transverse beam; the buffer plates are provided with at least two bumps facing the automobile body; the surfaces, facing the transverse beam, of the bumps are not in contact with the transverse beam; one end of each elastic body is fixed on the surface, which faces away from the transverse beam, of each bump; the other ends of the elastic bodies are fixedly connected with the connecting seats. When the transverse beam is collided, the collision acting force can be transferred onto the energy-absorbing boxes in time, so that the collision acting force among colliders is reduced.

Description

technical field [0001] The invention relates to a protective device on an automobile body, in particular to a bumper with a buffer structure. Background technique [0002] In motor vehicles, bumper bumpers are fitted as standard on the front and rear sides in order to absorb the impact energy of minor crashes so that the vehicle's own supporting structure is as little as possible damaged. The bumper bumper usually consists of a cross member which, when installed in a crash box, can be fastened transversely to the longitudinal members of the vehicle frame. The crossbeam is used to guide the energy caused by the impact into the crash box, where the impact energy is converted and absorbed. [0003] Although the energy-absorbing box can absorb energy during the collision process, as far as the assembly relationship between the energy-absorbing box and the beam is concerned, the energy-absorbing box is assembled at the two ends of the beam. For such an assembly structure, when t...

Problems solved by technology

[0003] Although the energy-absorbing box can absorb energy during the collision process, as far as the assembly relationship between the energy-absorbing box and the beam is concerned, the energy-absorbing box is assembled at the two ends of the beam. For such an assembly structure, when the front of the beam is impacted When the force is applied, the collision force is concentrated in the middle of the beam. In an instant, the beam cannot quickly transfer the collision force to the energy-absorbing box. The resulting problem is that if the force is too large, the beam will be directly damaged.
