Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy automobile anti-collision beams, in particular to a novel lightweight high-strength aluminum alloy automobile anti-collision beam. Background Art

[0002] Automobile anti-collision beams refer to a component designed in the vehicle structure to increase the safety performance of the vehicle in the event of a collision. These beams are usually installed at the front, rear and side of the vehicle to provide additional support and protection. They can be made of different materials, such as steel, aluminum alloy or carbon fiber composite materials, to reduce the impact force on vehicle occupants during a collision and reduce the risk of injury. There are at least the following disadvantages in the use of existing aluminum alloy automobile anti-collision beams: Most of the existing aluminum alloy automobile anti-collision beams are arc-shaped square tube structures with relatively simple structures. They are very easy to deform and break after collision, and have limited energy absorption for impact, thus affecting the protection effect. Therefore, we have launched a new type of lightweight high-strength aluminum alloy automobile anti-collision beam. Utility Model Content
