Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile rear bumpers, and particularly relates to an inner frame structure of an automobile rear bumper. Background Technique
[0002] Bumpers are provided at both the front and rear sides of a vehicle. The front bumper mainly serves a decorative function. In order to avoid serious injuries to pedestrians after a collision, there is no frame structure inside the front bumper. The rear bumper normally shields the rear anti-collision beam. Therefore, when the rear of the vehicle is impacted, the impact force is directly transmitted to the anti-collision beam. If the beam head connected to the anti-collision beam bends, then the vehicle becomes a severely damaged vehicle.
[0003] Most of the existing automobile rear bumpers are of concave structures. When the two ends of the automobile rear bumper are connected to the vehicle, the connection between the two ends of the bumper and the cross beam is usually only a bolt connection. When the vehicle collides, the connection between the two ends of the bumper and the cross beam is prone to shift, resulting in deformation of the automobile rear bumper and affecting the protection effect. For this reason, we propose an inner frame structure of an automobile rear bumper to facilitate increasing the anti-collision performance of the automobile rear bumper. Content of the Utility Model
[0004] In view of the problems in the prior art, the utility model provides an inner frame structure of an automobile rear bumper.

Reinforcement mechanisms are installed at both ends of the bumper main body. The reinforcement mechanism is composed of a support rod, a reinforcement plate, a base, a connecting plate and a locking bolt. Connecting plates are connected to both ends of the bumper main body through locking bolts. A support rod is welded to the bottom of the connecting plate. The other end of the support rod is welded to the base. One end of the rod wall of the support rod is connected to one end of the connecting plate through a bolt. The other end of the connecting plate is connected to the bottom of the bumper main body through a bolt.
[0006] By adopting the above technical solution, when increasing the anti-collision strength of the bumper main body, since reinforcement mechanisms are installed at both ends of the bumper main body, and the reinforcement mechanism is composed of a support rod, a reinforcement plate, a base, a connecting plate and a locking bolt. After the locking bolt passes through the connecting plate and is connected to the bumper, since the connecting plate and the base are welded and connected through the support rod, after the external bolt passes through the through hole at the base, the base is connected to the rear of the vehicle. One end of the reinforcement plate is connected to the rod wall of the support rod through a bolt, and the other end of the reinforcement plate is connected to the rod wall of the bumper main body through a bolt. The reinforcement plate forms a triangle with the bumper and the support rod, so as to realize the reinforcement of the support rod, and avoid the side bending of the support column when the bumper main body collides, resulting in deformation of the bumper main body and affecting the anti-collision performance.
[0007] Specifically, it includes an anti-collision mechanism, and the anti-collision mechanism is installed on the outer wall of the bumper main body.
[0008] By adopting the above technical solution, the anti-collision performance of the bumper main body can be increased through the anti-collision mechanism.
[0009] Specifically, the anti-collision mechanism is composed of a silica gel pad, a foam shock pad, and a rubber shock pad. The silica gel pad is adhered to the outer wall of the bumper main body, the foam shock pad is adhered to the outer wall of the silica gel pad, and the rubber shock pad is adhered to the outer wall of the foam shock pad.
[0010] By adopting the above technical solution, when increasing the anti-collision performance of the bumper main body, since the anti-collision mechanism is installed on the outer wall of the bumper main body, the anti-collision mechanism is composed of a silica gel pad, a foam shock pad, and a rubber shock pad. The silica gel pad is adhered to the outer wall of the bumper main body, the silica gel pad has good damping and shock absorption performance, the foam shock pad is adhered to the outer wall of the silica gel pad, the foam shock pad has good buffering performance, the rubber shock pad is adhered to the outer wall of the foam shock pad, and the rubber shock pad has good anti-collision performance, thereby increasing the anti-collision performance of the bumper main body.
[0011] Specifically, a cambered plate is installed at the arc of the bumper main body through bolts.
[0012] By adopting the above technical solution, the anti-piling performance of the bumper main body can be increased through the cambered plate.
[0013] Specifically, through holes for connecting with external bolts are opened on the outer wall of the base.
[0014] By adopting the above technical solution, it is convenient to connect the base to the vehicle by passing an external bolt through the through hole.
