Description

Vehicle body structure and vehicle Technical Field The application relates to the technical field of automobiles, in particular to a vehicle body structure and a vehicle. Background The cabin assembly is a main component of a vehicle body, and the structure of the front shock absorber assembly is used as an important collision force transmission path in the cabin, has the functions of absorbing and transmitting collision energy, protecting a passenger cabin and the like, so that the structure strength of the front shock absorber assembly of the automobile has a better structure in offset collision to meet the requirements. The existing connecting structure of the front shock absorber assembly and the front longitudinal beam assembly is usually directly connected, and when offset collision is carried out, the connecting point of the front shock absorber assembly and the front longitudinal beam assembly is easy to tear or the front end of the front shock absorber is broken, so that the offset collision requirement is difficult to meet. Disclosure of utility model The application mainly solves the technical problem of providing a vehicle body structure and a vehicle, which can improve the connection strength of a front shock absorber and a front longitudinal beam and meet the requirement of offset collision. In order to solve the technical problems, the technical scheme includes that the vehicle body structure comprises a front shock absorber tower assembly and a front longitudinal beam assembly, the front shock absorber tower assembly comprises a front shock absorber tower and a first reinforcing plate, a first buffer cavity is formed by surrounding the front shock absorber tower and the first reinforcing plate, the front longitudinal beam assembly comprises a front longitudinal beam and a second reinforcing plate, a second buffer cavity is formed by surrounding the front longitudinal beam and the second reinforcing plate, the front longitudinal beam is fixedly connected with the front shock absorber tower, and the first buffer cavity and the second buffer cavity are at least partially overlapped. Wherein the first reinforcing plate and the second reinforcing plate are at least partially overlapped. The first reinforcing plate is fixedly connected with the second reinforcing plate through bolts. Wherein, the second reinforcing plate set up in the first reinforcing plate deviates from the one side of preceding shock tower. The first reinforcing plate comprises a first main plate and a first side plate and a second side plate which are arranged on two sides of the first main plate respectively, the first side plate and the second side plate are fixedly connected with the front shock absorption tower, and the first main plate is arranged at intervals with the front shock absorption tower. The first side plate and the second side plate are fixedly connected with the front shock absorber through screws or rivets, and the first side plate and the second side plate are bonded with the front shock absorber through structural adhesive.
