Description

Technical Field

[0001] This utility model belongs to the field of rear bumper installation technology, specifically a modular fixing device for a vehicle rear bumper mounting bracket assembly. Background Technology

[0002] Currently, many automotive rear bumper bracket mounting structures suffer from insufficient strength. Some brackets use plastic clips for fixing, such as the commonly used method of connecting the bracket to the side panel of the vehicle body. However, plastic clips have low strength and are prone to breakage. Once damaged or loosened, the installation firmness of the rear bumper is affected, and the fit and surface difference between the bracket and the side panel of the vehicle body cannot be guaranteed, resulting in poor overall appearance and product quality.

[0003] Due to design and molding process limitations, some rear bumper brackets interfere with the welding clamps at the stop position of the welded rear bulkhead assembly after welding to the outer rear panel. This fails to meet welding process specifications, not only compromising installation strength but also making it impossible to weld the rear bulkhead assembly. Furthermore, CAE fatigue analysis simulations show that some rear bumper bracket contact areas with the outer rear panel have low lifespans, failing to meet vehicle body CAE durability performance targets and impacting the overall vehicle lifespan.

[0004] When a vehicle is involved in a rear-end collision, insufficiently strong supports cannot effectively transmit and disperse the impact force, causing the rear bumper to fail to fully perform its buffering and energy-absorbing function, greatly reducing its anti-collision effect and significantly increasing the risk of injury to occupants and serious damage to the rear structure of the vehicle.
