The invention relates to the technical field of manufacturing and production of automobiles and auxiliary frames, in particular to a lightweight metal plate front auxiliary frame of an electric automobile. According to the front auxiliary frame applied to the multi-type center sill of the electric automobile, a bent pipe head front connecting beam body can be omitted, the weight is greatly reduced, parts are reduced, the cost is reduced, and the structural strength and modality are further improved. Comprising a front cross beam, a rear cross beam, a left longitudinal beam and a right longitudinal beam, the left longitudinal beam and the right longitudinal beam are of consistent and symmetrical structures and comprise longitudinal beam upper folded plates, longitudinal beam lower head plates and longitudinal beam lower tail plates, cross beam clamping grooves are formed in the head ends of the longitudinal beam upper folded plates, the front cross beam comprises a front cross beam upper plate and a front cross beam lower plate, and the rear cross beam comprises a front cross beam lower plate and a rear cross beam lower plate. The front cross beam upper plate and the front cross beam lower plate are spliced and connected up and down, and the head end and the tail end of the front cross beam are buckled into the cross beam clamping groove to be connected with the left longitudinal beam or the right longitudinal beam into a whole; the rear cross beam comprises a rear cross beam upper plate and a rear cross beam lower plate which are connected in an up-and-down splicing mode, wide connection welded junctions are formed in the head end and the tail end of the rear cross beam, and the wide connection welded junctions are spliced to the lower ends of the left longitudinal beam and the right longitudinal beam in an engaged mode.
