The invention discloses an automobile front wall plate and rear cross beam connecting structure, which relates to the technical field of passenger vehicle bodies. The structure comprises a side wall assembly and a front wall plate assembly, a front column inner plate is fixedly installed on the side face of the side wall assembly, the front wall plate assembly is connected with the side wall assembly, a front wall plate side cross beam is arranged on the front face of the front wall plate assembly, and the other end of the front wall plate side cross beam is movably installed on the inner sideface of the front column inner plate. The front wall plate side cross beam is connected with the front column inner plate through a bolt; the problem that the front wall plate side cross beam is notconnected with the side wall assembly due to the design of a welding line and the limitation of welding equipment is solved, effective conduction of energy from the front wall plate side cross beam tothe side wall assembly in the vehicle collision process is achieved, under the conditions of design of a welding line and limitation of welding equipment, the problem that performance improvement cannot be achieved due to production conditions is solved through a bolt connection mode, and the vehicle collision performance and rigidity are improved.

    本发明公开了一种汽车前壁板后横梁连接结构,涉及乘用车车身技术领域。包括侧围总成和前壁板总成,所述侧围总成的侧面固定安装有前柱内板,所述前壁板总成与侧围总成相互连接,所述前壁板总成的正面设置有前壁板侧横梁,所述前壁板侧横梁的另一端与前柱内板的内侧面活动安装。利用螺栓将前壁板侧横梁与前柱内板实行连接,解决了因焊接线的设计及焊接设备的限制导致前壁板侧横梁与侧围总成无连接的问题,实现了车辆碰撞过程中能量在前壁板侧横梁至侧围总成的有效传导,使得在焊接线的设计及焊接设备的限制的条件下,通过采用螺栓连接形式,解决了因生产条件而无法解决性能提升的问题,提升了汽车碰撞性能及刚度。
