Description

Technical Field

[0001] This utility model relates to the field of automotive bumper technology, specifically a heavy-duty truck flip-up bumper. Background Technology

[0002] Heavy truck bumpers are important safety devices installed at the front of heavy trucks. They not only absorb and cushion the impact force of a collision, protecting critical internal components (such as the engine and radiator) from direct impact damage and reducing maintenance costs, but also provide some protection for pedestrians and vehicles, reducing the degree of injury to people in collision accidents. At the same time, as part of the vehicle's appearance, the design of the bumper also affects the overall appearance and aerodynamic performance of the vehicle.

[0003] In the current field of heavy truck bumper design, the vast majority of heavy truck bumpers adopt a fixed connection method, that is, the bumper is fastened to the front of the vehicle by welding, riveting or a large number of bolts. However, when it is necessary to inspect the components inside the front of the vehicle, this fixed connection bumper exposes obvious drawbacks. Because the bumper is difficult to disassemble, maintenance personnel often need to spend a lot of time and energy on the removal of the bumper.

[0004] For example, when repairing large components such as engines and transmissions, it may be necessary to remove multiple bolts around the bumper, and even use special tools to cut or separate some connecting structures. This not only increases the difficulty and workload of the repair work, but may also cause damage to the bumper during disassembly, affecting its performance and appearance after reinstallation. Moreover, when reinstalling the bumper after repair, it is also necessary to accurately align and firmly fix it, otherwise it may affect the vehicle's driving safety and overall appearance quality.

[0005] In view of the above, this application is hereby submitted. Utility Model Content
