The invention discloses an automobile anti-collision beam mounting structure and a mounting method. The automobile anti-collision beam mounting structure comprises an anti-collision beam, an automobile body longitudinal beam, a bolt, a reinforcing sleeve and a welding nut, the anti-collision beam is an arc-shaped cross beam matched with the outline shape of the front end of a vehicle body, the cross section of the anti-collision beam is of a hollow cavity structure, the two ends of the anti-collision beam are fixedly assembled with the front end face of a vehicle body longitudinal beam through bolts, and reinforcing sleeve assembly holes are formed in the inner side arc face and the outer side arc face of the matched position of the anti-collision beam and the front end face of the vehicle body longitudinal beam. A welding nut is pre-welded on the inner side wall of the front end surface of the vehicle body longitudinal beam; the two ends of the reinforcing sleeve are embedded in reinforcing sleeve assembly holes formed in the inner side arc face and the outer side arc face of the anti-collision beam respectively. The bolt penetrates through the reinforcing sleeve to be assembled with the welding nut. The strength of the joint of the anti-collision beam and the longitudinal beam of the automobile is effectively enhanced, the problem that a collision force transmission path is changed due to the fact that the anti-collision beam is pulled out too early at the joint is solved, and the purposes of improving the impact resistance of an automobile body and guaranteeing the safety of the automobile are achieved.

    一种汽车防撞梁安装结构及安装方法,所述汽车防撞梁安装结构包括防撞梁、车体纵梁、螺栓、加强套筒和焊接螺母;所述防撞梁为与车体前端外廓形状相匹配的弧形横梁,其横截面为空心型腔结构,防撞梁的两端通过螺栓与车体纵梁的前端面固定装配,在与车体纵梁前端面配合处的内、外侧弧面上均开设加强套筒装配孔;所述车体纵梁的前端面内侧壁上预焊有焊接螺母;所述加强套筒两端分别嵌装在设置于防撞梁内、外侧弧面的加强套筒装配孔中;所述螺栓穿过加强套筒与焊接螺母装配。本发明有效地增强了汽车防撞梁与纵梁连接处强度、避免了因防撞梁在连接处过早拉脱导致的改变碰撞力传递路径问题,达到了提高车体抗冲击能力、保证车辆安全性的目的。
