Description

Technical Field

[0001] The utility model relates to the field of front bumpers, in particular to a front bumper assembly. Background Art

[0002] The front bumper is located at the front of the vehicle, below the hood. The front bumper of a motor vehicle is made of plastic. Its main function is to protect pedestrians and other vehicles. When a collision occurs, it can effectively buffer and avoid injuries. The front bumper is generally made of two materials: metal and plastic. Among them, the plastic bumper assembly is generally composed of a plastic bumper body, a metal frame and a connecting bracket, and the bumper assembly is installed on the frame through the connecting bracket.

[0003] In the prior art, the front bumper assembly includes a bumper body, a bumper frame fixedly connected to the inner side of the bumper body, and a connecting bracket fixedly connected to the vehicle frame. The connecting bracket is arranged at the lower inner side of the bumper body. Specifically, at the lower part of the bumper body, the connecting bracket is connected to the lower part of the connecting bracket by bolts. The connecting bracket is L-shaped, and the upper end of the connecting bracket is connected to the vehicle frame by bolts. By using the L-shaped connecting bracket, the bumper body has a better supporting effect and is prevented from falling.

[0004] When the above technical solution is adopted, the bumper body is connected to the connecting bracket by bolts. When the bumper body is hit, only the connecting bolts provide support for the bumper body along the impact direction. The support strength is weak and easy to deform. After the bumper body is hit, the deformation of the lower part is greater than the middle and upper part of the bumper body, so that the energy absorption and buffering function of the middle and upper part of the bumper body cannot be fully exerted. In addition, the contact area between the middle and upper part of the bumper body and the pedestrian is large, resulting in poor protection for pedestrians. Utility Model Content

[0007] Furthermore, a buffer slope is provided at one end of the limiting boss close to the connecting portion. The buffer slope can enable the limiting boss to smoothly move to the bottom of the connecting portion under impact, thereby avoiding a hard collision between the connecting portion and the limiting boss and causing deformation of the connecting piece.

[0008] Furthermore, a reinforcing plate is provided on the inner wall of the lower part of the bumper body near the connecting piece. The reinforcing plate is provided to further enhance the strength of the lower part of the bumper body and reduce impact deformation.

[0013] Furthermore, the upper support member is in a C-shaped structure, the opening of the upper support member is upward, and a frame connecting plate and a grille connecting plate are respectively provided at both ends of the upper support member.

[0014] Furthermore, along the driving direction of the vehicle, the middle support extends backward, the thickness of the middle support increases gradually, and a clamping hole is vertically arranged at the rear end of the middle support, and the clamping hole can be clamped with a clamping tongue on the frame. The middle support is clamped and connected with the frame, which facilitates the installation of the grille.

[0015] Furthermore, the middle support member is provided with reinforcing ribs, and the reinforcing ribs extend backwards. The strength of the middle support member is enhanced by providing the reinforcing ribs.
