Description

Technical Field

[0001] This utility model relates to the field of automotive rear bumpers, specifically a lightweight automotive rear bumper bracket. Background Technology

[0002] Car bumpers serve multiple purposes, including safety protection, vehicle aesthetics, and improving aerodynamics. From a safety perspective, they act as a buffer in low-speed collisions, protecting the front and rear of the vehicle; and in accidents involving pedestrians, they can offer some protection.

[0003] Chinese Patent Publication No. CN221418172U discloses a lightweight automotive rear bumper, including a bumper body comprising an upper main guard plate, a lower guard plate, and side guard plates. The upper main guard plate includes a middle main guard plate and a transition guard plate. The middle main guard plate protrudes forward from the transition guard plate and has a reinforcing inner liner installed on its back. A strip-shaped cavity is provided on the lower edge of the transition guard plate, and a reflector is embedded in the strip-shaped cavity. The lower guard plate has a decorative main plate and a transition auxiliary plate. The decorative main plate corresponds to the middle main guard plate and is recessed, and an outer decorative panel is installed on the decorative main plate. This utility model achieves a lightweight design by integrally molding the upper main guard plate, lower guard plate, and side guard plates into the bumper body. The middle main guard plate, together with the transition guard plate, forms the upper main guard plate, with a reflector embedded in the strip-shaped cavity to enhance warning and improve safety. The decorative main plate, together with the transition auxiliary plate, forms the lower guard plate, enhancing the decorative effect of the outer liner.

[0004] When the aforementioned bumper bracket is installed on a vehicle, the vehicle body may become covered in static electricity in relatively dry weather. Traditional bumper brackets cannot eliminate static electricity on the vehicle body, and static electricity will be generated when the driver gets in and opens the door. Furthermore, the presence of static electricity on the vehicle body will increase the risk of spontaneous combustion for electric vehicles. Utility Model Content

[0005] The purpose of this utility model is to provide a lightweight automotive rear bumper bracket. A main connecting piece is provided at the lower end of the mounting bracket, and a fixed connecting block is provided at the lower end of the main connecting piece. A first connecting piece is provided on the end of the fixed connecting block away from the main connecting piece, and a second connecting piece is provided on the first connecting piece. The two are connected by bolts passing through through holes in the connecting pieces. A detachable connecting block is provided on the end of the second connecting piece away from the first connecting piece, and both ends of the detachable connecting block have second connecting pieces. After the mounting bracket is fixed to the vehicle frame, the operator can observe the distance between the vehicle chassis and the ground to appropriately increase the number of detachable connecting blocks on the fixed connecting block, ensuring that the last detachable connecting block is perpendicular to the ground. Furthermore, if the last detachable connecting block becomes worn and its length is insufficient to contact the ground after prolonged use, simply loosen the fixing bolts between the two detachable connecting blocks and replace it with a new detachable connecting block. This solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight automotive rear bumper bracket, including a mounting bracket, a first weight-reducing groove on the mounting bracket, and a main connecting piece, the main connecting piece being disposed at the lower end of the mounting bracket, the main connecting piece having bolt holes, a fixing connecting block being disposed at the lower end of the main connecting piece, a first connecting piece being disposed at the lower end of the fixing connecting block, a second connecting piece being disposed on the first connecting piece, and a detachable connecting block being disposed at the end of the second connecting piece away from the first connecting piece.

[0007] Preferably, the mounting bracket has a second weight-reducing groove on one side of the first weight-reducing groove.

[0008] Preferably, the mounting bracket is provided with a bumper, and the bumper and the mounting bracket are integrally connected.

[0009] Preferably, a reinforcing rib is provided at the angle between the bumper and the mounting.

[0010] Preferably, the upper outer surface of the bumper is provided with a mounting slot, and the mounting slot is integrally formed with the bumper.

[0011] Preferably, both ends of the bumper are provided with connecting blocks, which are welded to the bumper.

[0012] Preferably, the mounting bracket is provided with connecting fins at both the left and right ends.

[0013] Preferably, the mounting bracket is provided with a mounting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model comprises a main connecting piece at the lower end of a mounting bracket, a fixed connecting block at the lower end of the main connecting piece, a first connecting piece at the end of the fixed connecting block away from the main connecting piece, and a second connecting piece at the first connecting piece. The two are connected by bolts passing through through holes in the connecting pieces. A detachable connecting block is located at the end of the second connecting piece away from the first connecting piece, and both ends of the detachable connecting block have second connecting pieces. After the mounting bracket is fixed to the vehicle frame, workers can observe the distance between the vehicle chassis and the ground to appropriately add detachable connecting blocks to the fixed connecting block. The quantity ensures that the last detachable connecting block is perpendicular to the ground. If the last detachable connecting block becomes worn and its length is insufficient to contact the ground after prolonged use, simply loosen the fixing bolts between the two detachable connecting blocks and replace it with a new detachable connecting block. This effectively avoids the problem that when existing bumper brackets are installed on vehicles, the car body may become covered in static electricity in relatively dry weather. Traditional bumper brackets cannot eliminate static electricity on the car body, which will cause static electricity when the driver gets in and opens the door. Furthermore, static electricity on the car body also increases the risk of spontaneous combustion for electric vehicles. Attached Figure Description
