Description

Technical Field

[0001] The utility model relates to the technical field of collision structures, in particular to an assembled truck anti-collision beam. Background Art

[0002] The anti-collision beam is an important part of the vehicle safety system and is usually located in the front and rear body structures of the vehicle. Its main function is to absorb and disperse the collision energy in a vehicle collision accident and protect the vehicle occupants from serious injuries.

[0003] When the applicant was making this application, after searching, he found that a Chinese patent disclosed an "anti-collision beam assembly", and its application number is "CN202010195100.X". This patent mainly includes an anti-collision beam, a first energy absorption box and a second energy absorption box. The first energy absorption box and the second energy absorption box are respectively arranged at both ends of the anti-collision beam, and the first energy absorption box and the anti-collision beam are rotatably connected through a first rotating shaft, and the second energy absorption box and the anti-collision beam are rotatably connected through a second rotating shaft. When the anti-collision beam assembly collides, the anti-collision beam and the first energy absorption box or the second energy absorption box form a rotating pair, which reduces the peak force at the initial moment of the collision and reduces the risk of tearing failure of the first energy absorption box and the second energy absorption box. However, this structure is not easy to disassemble, and it is not convenient to regularly maintain the internal structure. For this reason, we propose an assembled truck anti-collision beam to solve the above problems. Utility Model Content
