The invention discloses an automobile body structure and an automobile. The automobile body structure comprises an A column, an automobile door assembly, an engine compartment assembly and an engine compartment upper longitudinal beam and further comprises an upper longitudinal beam reinforcing plate, a first anti-collision beam and a second anti-collision beam, the front end of the upper longitudinal beam reinforcing plate is connected with the middle of the engine compartment upper longitudinal beam, the rear end of the upper longitudinal beam reinforcing plate is connected with the engine compartment assembly, the engine compartment upper longitudinal beam and the upper longitudinal beam reinforcing plate form a first triangular area on the engine compartment assembly; the first anti-collision beam and the second anti-collision beam are installed on a vehicle door assembly in the front-back direction of a vehicle body, and the first anti-collision beam is located above the second anti-collision beam. By improving the force transmission structure and increasing the force transmission path during collision, the problems that the small offset collision performance of an existing automobile does not reach the standard, the weight of an automobile body is heavy and the cost is high due to the fact that the local structure of the automobile body is reinforced are solved, and the problem that the automobile body is impacted by the chassis due to the fact that wheels are connected with the chassis during collision is solved.
本发明公开了一种车身结构及汽车,包括A柱、车门总成、发动机舱总成和发动机舱上纵梁,还包括上纵梁加强板、第一防撞梁和第二防撞梁,上纵梁加强板的前端与发动机舱上纵梁的中部连接,上纵梁加强板的后端与发动机舱总成连接,发动机舱上纵梁和上纵梁加强板在发动机舱总成上形成第一三角区域;第一防撞梁和第二防撞梁沿车身前后方向安装在车门总成上,第一防撞梁位于第二防撞梁的上方。本发明通过改善传力结构和增加碰撞时的传力路径,解决了现有汽车小偏置碰撞性能不达标,而通过车身局部结构加强的方式造成车身重量较重、成本较高的问题,并且避免了碰撞时车轮和底盘连接导致底盘对车身造成冲击的问题。
