Abstract

The invention relates to a vehicle body front longitudinal beam structure, and belongs to the technical field of vehicle design and manufacturing. The vehicle body front longitudinal beam structure comprises a front longitudinal beam assembly, an upper edge beam assembly, a front longitudinal beam connecting plate assembly, an upper edge beam front section assembly, a front anti-collision beam energy absorption box assembly and a front anti-collision beam assembly. According to the vehicle body front longitudinal beam structure, the force transmission path is optimized, the energy absorption capacity of the front end of the vehicle body is effectively improved, the load of the cabin longitudinal beam is reduced, the invasion amount of a front cabin to a passenger cabin is reduced or avoided, and the safety of a driver is improved.

Description

technical field [0001] The invention relates to the technical field of automobile design and manufacture, more specifically, the invention relates to a vehicle body front longitudinal beam structure. Background technique [0002] At present, domestic automobile consumers pay more and more attention to the safety evaluation of automobile collision. Among them, offset collision is one of the evaluation items, including 25% and 40% offset collision, that is, the overlapping area between the vehicle and the collision object is equivalent to 25% and 40% of the width of the vehicle body. The smaller the overlapping area, the greater the impact pressure on the car, and the stricter the collision requirements for the body. [0003] At present, most models on the market mainly transmit the collision force through the front longitudinal beam during collision, thereby reducing the amount of intrusion of the front cabin into the passenger compartment. However, since the collision forc...
