The utility model provides a box body structure and a battery pack. The box body structure comprises a main box body as well as side beams, longitudinal beams and cross beams which are arranged in the main box body, the side edge beams are fixedly connected to the inner walls of all the sides of the main box body, and the adjacent side edge beams are fixedly connected. The two ends of the longitudinal beam are fixedly connected with the two side beams respectively; the cross beams are fixedly connected with the longitudinal beams in a crossed mode, and the two ends of each cross beam are fixedly connected with the two side beams respectively. According to the arrangement, all the side edge beams, the transverse beams and the longitudinal beams form a frame structure, the inner wall of the main box body is reinforced, the structural stability of the main box body is enhanced, the longitudinal beams and the transverse beams which are connected in a crossed mode have good load bearing capacity, and therefore a s
