The invention belongs to the technical field of vehicle engineering, and particularly relates to a side opening type back door hinge installation supporting column, a D column structure and a back door frame. The side-opening type back door hinge installation supporting column comprises a first combined lamp holder plate assembly and a first stand column. The upper end of the first stand column is fixedly connected with one end of a top cover rear beam of the vehicle. The lower end of the first stand column is fixedly connected with one end of a rear floor rear beam of the vehicle. The first stand column is of a tubular structure, and the outer side face, in the left-right direction of the vehicle, of the first stand column is used for being welded to the inner side face of a first side wall outer plate of the vehicle. The outer end, in the left-right direction of the vehicle, of the first combined lamp holder plate assembly is used for being connected with the rear end of a first side wall outer plate in a welded mode, the inner end, in the left-right direction of the vehicle, of the first combined lamp holder plate assembly is connected with the first stand column in a welded mode, and a first inner cavity extending vertically is formed between the first stand column and the first combined lamp holder plate assembly. And a back door upper hinge mounting hole and a back door lower hinge mounting hole are formed in the first combined lamp holder plate assembly.
