Back door hinge mounting structure and automobile

Abstract

The invention provides a back door hinge mounting structure, and belongs to the technical field of automobiles, a first structural member is arranged in a D-column outer cavity, one end of the first structural member is connected with a gutter channel, the other end of the first structural member is connected with a D-column reinforcing plate, a second structural member is arranged in a D-column inner cavity, one end of the second structural member is connected with the D-column reinforcing plate, and the other end of the second structural member is connected with a D-column inner plate; wherein the first structural member and the second structural member are connected with each other. According to the back door hinge mounting structure provided by the invention, the first structural part is mounted in the D-column outer cavity so as to increase the structural strength of the D-column outer cavity, and the second structural part is mounted in the D-column inner cavity so as to increase the structural strength of the D-column inner cavity. Meanwhile, the first structural part and the second structural part are connected with each other, and the D-column outer cavity and the D-column inner cavity are associated with each other, so that the structural strength of the back door hinge mounting structure is improved, the problem that a back door droops is avoided, it is ensured that after the back door is matched with a rear tail lamp and a side wall, a gap face can meet theoretical design, and the delicate appearance of a whole vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and more specifically relates to a rear door hinge installation structure and an automobile. Background technique [0002] The rear door hinge is located in the rear gutter area of ​​the vehicle body, providing a fixed point for the rear door to ensure the installation strength and rigidity requirements of the rear door. The conventional rear door hinge installation structure is composed of a side wall outer panel, a gutter, a D-pillar reinforcement panel and a D-pillar inner panel. The side wall outer panel, the water tank and the D-pillar reinforcement panel form the D-pillar outer cavity, and the D-pillar reinforcement panel and the D-pillar inner panel form the D-pillar inner cavity. [0003] Among them, the outer cavity of the D-pillar and the inner cavity of the D-pillar are superimposed along the X-direction of the car body, and there is no other related structure, so that the rigidit...
