The invention particularly relates to a hatchback door metal plate structure and an automobile. The metal plate structure comprises a back door inner plate, two hinge reinforcing plates, an upper reinforcing plate, two side reinforcing plates and a middle reinforcing plate. The hinge reinforcing plates, the upper reinforcing plate, the side reinforcing plates and the middle reinforcing plate are all arranged on the back door inner plate, the two hinge reinforcing plates are arranged on the two sides of a window frame respectively and cover a hinge mounting area at the same time, the upper reinforcing plate is arranged on the upper portion of the window frame, and the two side reinforcing plates are arranged on the lower left portion and the lower right portion of the window frame respectively. The middle reinforcing plate is arranged below the window frame; the two hinge reinforcing plates, the upper reinforcing plate, the two side reinforcing plates and the middle reinforcing plate are all welded to the window frame and welded to the window frame in a lap joint mode. A double-ring welding structure is adopted, so that the reinforcing plates form a whole while meeting the local rigidity, various supports are formed between the inner plate and the outer plate, and the rigidity and modality are improved. The automobile uses the metal plate structure of the hatchback tail door.
