The invention discloses a back door multi-connecting-rod hinge mounting point structure which comprises a D-column inner plate and a back door frame body, and a water flowing groove is formed in the back door frame body. A D-column reinforcing rib plate is arranged between the D-column inner plate and the gutter channel, and bosses are arranged on the D-column reinforcing rib plate and correspond to the positions, hinged to the gutter channel and the multiple connecting rods, of the gutter channel respectively. A projection welding nut is arranged on the inner side of the boss, and the axis of the projection welding nut is perpendicular to the groove bottom of the water flowing groove. Connecting holes are formed in the positions, corresponding to the projection welding nuts, of the bottom of the boss and the bottom of the gutter channel. When the hinge mounting points are stressed, force can be transmitted to the whole back door frame, so that the rigidity performance of the hinge mounting points is remarkably improved, and the mounting stability of the whole back door is improved.

    本发明公开了一种背门多连杆铰链安装点结构,包括D柱内板和背门框体,所述背门框体上成型有流水槽;在D柱内板与流水槽之间设有D柱加强筋板,在D柱加强筋板上,对应流水槽与多连杆的各铰链位置分别设有一凸台;在该凸台内侧设有凸焊螺母,且所述凸焊螺母的轴心线垂直于流水槽的槽底;在凸台及流水槽的槽底,对应凸焊螺母的位置设有连接孔。本发明当铰链安装点受力时,能将力传递到整个背门框上,从而显著提升铰链安装点的刚度性能,进而提升整个背门的安装稳定性。
