The invention relates to an automobile front wall plate assembly structure which comprises a middle reinforcing cross beam, a left side connecting reinforcing beam, a right side connecting reinforcing beam and a middle reinforcing longitudinal beam which are arranged on a front wall plate, the middle reinforcing cross beam is in a long strip shape, the cross section of the middle reinforcing cross beam is of an omega-shaped structure, and the middle reinforcing cross beam is tightly connected with the front side of the front wall plate to form a cavity. The left side connecting reinforcing beam is in an L shape, comprises a front floor left connecting section, a side wall left connecting section and a left right-angle area and is connected with the left side of the rear side of the front wall plate in a fastened mode through structural adhesive. The end of the front floor left connecting section of the left connecting reinforcing beam is located on the edge of the lower portion of the front wall plate and connected with a front floor assembly, and the end of the side wall left connecting section is located on the edge of the left side of the front wall plate and connected with a side wall connecting assembly. The middle reinforcing longitudinal beam is located on the rear side of the front wall plate, the cross section of the middle reinforcing longitudinal beam is M-shaped, and the middle reinforcing longitudinal beam is fixedly connected with the lower portion of the rear side of the front wall plate through structural adhesive. The automobile front wall plate assembly structure is high in integration level, light in weight, capable of meeting the automobile collision requirement and low in manufacturing cost.
