Abstract
The invention relates to the field of automobiles, in particular to an automobile back floor structure. The automobile back floor structure comprises a back floor assembly, a back floor framework and a back outer plate. A spare tire limiting device is arranged on the lower surface of the back floor assembly. The spare tire limiting device is used for limiting a spare tire to a preset position. The spare tire limiting device comprises a horizontal limiter and a vertical limiter. The horizontal limiter prevents the spare tire from moving along a horizontal direction. The vertical limiter prevents the spare tire from moving along a vertical direction. Therefore, the spare tire is prevented from swaying, and abrasion of the back floor assembly is reduced. According to the automobile back floor structure, limiting blocks clamp the spare tire so that the spare tire is prevented from moving along the horizontal direction, and preferably, the limiting blocks comprise an outer stopping block and an inner stopping block which play a role together to further prevent the spare tire from moving along the horizontal direction.
