The invention belongs to the field of new energy automobile chassis and rear auxiliary frames, and particularly relates to a new energy automobile rear auxiliary frame with a modified box type structural cross beam, which is used for being mounted on a new energy automobile. A special multilayer stacked front cross beam structure for changing the properties of the cross beam in the prior art is broken through, an upper piece, a lower piece and a stacked metal plate body structure which can be flexibly replaced are adopted, a manufactured piece body is matched with an internal arrangement structure as much as possible, additional working procedures such as stamping, shaping and bending are reduced, the production cost is reduced, the upper piece and the lower piece are suitable for various types, and the production efficiency is improved. Design and replacement are easy; the rear auxiliary frame is used for being installed on a new energy automobile and comprises a front cross beam, a rear cross beam, a left longitudinal beam and a right longitudinal beam, the front cross beam and the rear cross beam are vertically arranged in parallel, the right longitudinal beam and the front cross beam are arranged on the left side and the right side to be spliced with the front cross beam and the rear cross beam to form the rear auxiliary frame of a frame body structure, the left longitudinal beam and the right longitudinal beam are of an arc-shaped hydraulic pipe body structure, and longitudinal beam lining seats are arranged at the head end and the tail end of the left longitudinal beam and the tail end of the right longitudinal beam. And a rear auxiliary frame bushing is arranged in the longitudinal beam bushing seat.
