• wherein the battery pack frame comprises a plurality of adapter assemblies for pre-mounting two adjacent frame beams of the plurality of frame beams;
• at least one adapter assembly of the plurality of adapter assemblies is arranged between any of the two adjacent frame beams;
• each adapter assembly of the plurality of adapter assemblies comprises a threaded connection assembly and an inserting limiting assembly;
• the inserting limiting assembly is configured to limit relative positions of the two adjacent frame beams;
• the threaded connection assembly is configured to pre-connect the two adjacent frame beams;
• the two adjacent frame beams are pre-mounted through the each adapter assembly and then welded, each frame beam of the plurality of frame beams is a hollow beam body with a rectangular cross section, the at least one adapter assembly is arranged in a cavity of the each frame beam in a penetrating manner and is located at an end of the each frame beam, a weld between the two adjacent frame beams is a rectangular annular weld, and the rectangular annular weld is arranged around the at least one adapter assembly, a surface where an end opening of the each frame beam is located is inclined relative to a surface perpendicular to an extension direction of the each frame beam;
• the inserting limiting assembly comprises an inserting protrusion arranged in the cavity of the each frame beam, wherein an end of the inserting protrusion protrudes from the end opening but does not protrudes from the each frame beam;
• an inserting groove is formed in an end opening of another frame beam of the two adjacent frame beams;
• the two adjacent frame beams are matched with the inserting groove by means of the inserting protrusion in an inserted manner, a reinforced beam set is arranged in the cavity of the each frame beam, a part, protruding from the end opening, of the reinforced beam set forms the inserting protrusion, and the inserting groove is arranged at one end of the reinforced beam set which does not protrude from the end opening, the each frame beam comprises two oppositely arranged side beams, wherein an auxiliary support beam is integrally arranged at a bottom of each of the side beams, and two auxiliary support beams at bottoms of the two oppositely arranged side beams are oppositely arranged;
• and
• the frame body further comprises a main support beam arranged between the two auxiliary support beams and connected to the two auxiliary support beams, wherein the main support beam and the two auxiliary support beams are configured to jointly support the battery pack body, liquid-cooled channels are distributed on the main support beam and the auxiliary support beam, and the liquid-cooled channels are configured to cool the battery pack body.
