Vehicle body structure and vehicle

Abstract

Provided in the present application are a vehicle body structure and a vehicle. The vehicle body structure comprises a center tunnel, a front anti-collision beam, a first longitudinal beam, a front-wall cross beam assembly, a second longitudinal beam, and an intermediate energy absorption structure located in a frame structure and connected to the front-wall cross beam assembly. In a projection plane perpendicular to the height direction of the vehicle, the projection of the intermediate energy absorption structure at least partially overlaps that of the center tunnel. At least a middle portion of the front anti-collision beam located between the first longitudinal beam and the second longitudinal beam is a straight section. By means of the intermediate energy absorption structure, an intermediate force transmission channel located between the first longitudinal beam and the second longitudinal beam is established, so as to compensate for the inability of the first longitudinal beam and the second longitudinal beam to directly participate in support during collision of a central pillar, and to prevent a columnar barrier from invading a vehicle, thereby ensuring the safety of occupants in the vehicle. Furthermore, since the straight section of the front anti-collision beam collides with the barrier, intrusion into the barrier can be avoided during MPDB collision, thereby ensuring that no fatal damage is caused to the barrier.
