The invention belongs to the technical field of new energy passenger cars, and particularly discloses a lightweight aluminum alloy battery cover which is mainly made of aluminum profiles and comprises a cover body frame, a front end face, a rear end face, a top access door and side access doors. The front end face and the rear end face are fixed to the cover body frame in a bonding or welding mode, the top access door is fixed to the upper end face of the cover body frame through hinges, and the side access doors are fixed to the left end face and the right end face of the cover body frame through hinges. The cover body frame is of a cubic structure, the transverse frame is a cross beam, the longitudinal frame is a side longitudinal beam, the vertical frame is a side stand column, a middle longitudinal beam is arranged on the upper end face of the cubic structure, a front stand column is arranged between the front end face and the rear end face, and a middle cross beam is further arranged on the upper end face. The cover body frame is formed through integral welding. The structure is simple, the design is reasonable, the special section design meets the requirements of modeling, functions and the like, meanwhile, the top access door and the side access door enable maintenance to be convenient, the production efficiency is improved, and the production and use cost is reduced.
