The invention discloses a VAN vehicle D column back door hinge mounting structure and method, and belongs to the field of automobile manufacturing. The hinge mounting structure comprises a column D, a hinge supporting assembly is fixed to the inner wall of the column D and comprises a hinge supporting ring, a mounting plate is fixed to the hinge supporting ring, a first through hole is formed in the column D, and a hinge mounting hole corresponding to the through hole is formed in the mounting plate; the hinge mounting method comprises the steps that firstly, the mounting plate is welded to the hinge supporting ring to form the hinge supporting assembly, then, the hinge supporting assembly is welded to the inner wall of the D column, and finally, the D column outer plate is welded to the D column inner plate through the D column connecting plate to form the D column. The back door hinge installation structure is installed on the inner wall of the D column through the hinge supporting assembly, the rigidity and the anti-fatigue performance of the back door hinge installation structure can be effectively improved, the surface rigidity of the D column can be well improved, and therefore the overall structural rigidity of the D column is improved, the performance of a whole vehicle body is improved, and the reliability of the vehicle body is improved.
本发明公开一种VAN车D柱背门铰链安装结构及方法,属于汽车制造领域。该铰链安装结构包括D柱,D柱的内壁上固定有铰链支撑组件,铰链支撑组件包括铰链支撑环,铰链支撑环上固定有安装板,D柱上设有第一通孔,安装板设有与通孔对应的铰链安装孔;该铰链安装方法包括首先将安装板焊接至铰链支撑环上组成铰链支撑组件,然后将铰链支撑组件焊接在D柱的内壁上,最后将D柱外板通过D柱连接板焊接在D柱内板上形成D柱。本发明通过铰链支撑组件安装至D柱内壁,此结构既能有效地增加了背门铰链安装结构刚度和抗疲劳性能,又能很好地提升D柱的表面刚度,从而提升D柱整体的结构刚度,进而提升整个车身性能,提升车身的可靠性。
