The invention relates to the technical field of automobiles, in particular to a rear collision beam welding assembly, a body-in-white welding assembly and an automobile. A left connecting piece and a right connecting piece are arranged at the left end and the right end of a rear anti-collision beam body correspondingly; the left connecting piece is used for correspondingly connecting and fixing the rear anti-collision beam body and the left end of the rear portion of a body-in-white welding assembly, and the right connecting piece is used for correspondingly connecting and fixing the rear anti-collision beam body and the right end of the rear portion of the body-in-white welding assembly. The rear portion of the rear anti-collision beam body is provided with the rear anti-collision beam upper supporting plate, the multiple reinforcing supporting blocks used for improving the connecting strength between the rear anti-collision beam body and the rear anti-collision beam upper supporting plate are welded to the corners of the rear anti-collision beam body and the rear anti-collision beam upper supporting plate, and the rear anti-collision beam body and the rear anti-collision beam upper supporting plate are arranged on the rear anti-collision beam body and the rear anti-collision beam upper supporting plate. A plurality of vertical bolt holes are formed in the middle of the rear anti-collision beam body; the problem that the connecting strength of the rear collision beam and a vehicle body is insufficient can be solved at least.

    本发明涉及汽车技术领域,具体而言,涉及一种后碰撞横梁焊接总成、白车身焊接总成及汽车,所述后防撞梁本体的左右两端分别设置有左连接件和右连接件,所述左连接件用于将所述后防撞梁本体与白车身焊接总成后部的左端对应连接固定,所述右连接件用于将所述后防撞梁本体与白车身焊接总成后部的右端对应连接固定;所述后防撞梁本体的后部设置所述后防碰撞梁上支撑板,且所述后防撞梁本体与所述后防碰撞梁上支撑板的拐角处焊接有多个用于提高其间连接强度的所述加强支撑块,所述后防撞梁本体与所述后防碰撞梁上支撑板之上;所述后防撞梁本体的中部开设有若干个竖向螺栓孔;其至少能够解决后碰撞横梁与车身连接强度不足的问题。
