TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile ornaments, and particularly relates to a bumper center support. BACKGROUND

[0002] With the development of the times, the automobile becomes the necessary traffic tool for people to travel. The front and rear ends of the automobile are provided with bumpers. When a collision accident occurs, the bumper can first contact the collision object and absorb and moderate the impact force generated thereby, thereby protecting the vehicle body and the safety of passengers. A bumper center support is arranged between the bumper and the vehicle body,

[0003] The bumper center support, as a structural part, mainly plays a role in supporting the bumper to ensure the firm connection of the bumper and the vehicle body.

[0004] This supporting role enables the bumper to remain stable during vehicle driving and prevents the bumper from falling off or deforming due to external forces. At the same time, when a vehicle collision occurs, the bumper support is made of plastic, which is more elastic. When a vehicle collides with a pedestrian, the plastic part can effectively absorb the impact force and reduce the harm to the pedestrian.

[0005] However, the existing bumper center support structure is relatively simple, and the buffering effect is limited during use. When the bumper collides with a hard object, the collision potential energy transmission direction is relatively single, and the protection effect is limited. When the bumper collides with a pedestrian, the energy absorption effect is also general, and the protection of the pedestrian is also limited. Therefore, it is necessary to further improve the buffering effect of the bumper center support and reduce the harm caused by the collision. SUMMARY
