The invention provides a short carbon fiber composite (SCFC)-high-strength steel (HSS) hybrid bionic structure battery compartment and an integrated forming method thereof. A lower box body of the SCFC-HSS hybrid bionic structure comprises a bionic high-strength steel lower box body framework and an SCFC lower box body base body, and is characterized in that the SCFC-HSS hybrid bionic structure lower box body is arranged in the SCFC-HSS hybrid bionic structure battery compartment, and the SCFC-HSS hybrid bionic structure lower box body is arranged in the SCFC-HSS hybrid bionic structure battery compartment; and the upper box body and the lower box body are connected through bolts to form the complete SCFC-HSS hybrid bionic structure battery compartment. According to the battery compartment lower box body, a high-strength steel lower box body framework scheme is designed based on the bionics principle, a bionic lower box body framework structure is obtained through welding and surface treatment, and then the bionic lower box body framework structure is placed in a mold to be subjected to integrated injection molding through an SCFC base material. The SCFC-HSS hybrid bionic structure battery compartment overcomes the defects that a high-strength steel battery compartment is heavy and an aluminum alloy and carbon fiber composite material battery compartment is high in cost, realizes light weight and high performance of the battery compartment, has the characteristics of simple forming process, high efficiency and low cost, and has a wide application prospect.
