The invention belongs to the technical field of automobile parts, and particularly relates to a rear auxiliary frame of a new energy automobile, which comprises a front cross beam, a rear cross beam, a left longitudinal beam and a right longitudinal beam which are integrally cast, the front cross beam and the rear cross beam are upwards arranged in parallel, the left longitudinal beam is vertically connected with the head ends of the front cross beam and the rear cross beam, and the right longitudinal beam is connected with the tail ends of the front cross beam and the rear cross beam. For the front cross beam, the rear cross beam, the left longitudinal beam and the right longitudinal beam, a stress lap bend is arranged in the center of the left longitudinal beam and the center of the right longitudinal beam, a component force supporting column is arranged on the outermost side of the stress lap bend, the right longitudinal beam is formed by casting and combining a right longitudinal beam upper plate and a right longitudinal beam lower plate which are located on the upper side and the lower side, the rear cross beam comprises a left lower cross beam and a right lower cross beam, and a semi-connection lower cross beam is arranged between the left lower cross beam and the right lower cross beam. A stress half cover is arranged at the bottom of the semi-connection lower cross beam. The manufacturing cost and the product weight are reduced to the greatest extent while the mounting positions of parts of a chassis system are guaranteed and the performance requirements of enough modality, safe collision and the like are met, and meanwhile, the overall rigidity and strength of the rear auxiliary frame are improved as much as possible.
