[0011] As a further solution of the utility model, the cross-section of the side bracket is L-shaped, one end of the side bracket is in contact with the bottom wall of the longitudinal beam, and the projection welding nut is welded to the bottom wall of the longitudinal beam.

[0012] The beneficial effects of the utility model are:

[0013] The battery pack is directly connected to the longitudinal beam of the vehicle through the side bracket on the battery pack, which reduces the battery pack's encroachment on the Z-direction space of the vehicle body, increases the ground clearance of the battery pack, and facilitates increasing the capacity and size of the battery pack, thereby facilitating the improvement of the vehicle's carrying capacity;

[0014] The side bracket realizes convenient disassembly and assembly by means of mounting bolts and connecting bolts, and the convex welded nuts arranged on the longitudinal beam increase the stability of the connection between the mounting bolts and the longitudinal beam, and the first reinforcing plate on the longitudinal beam and the first reinforcing plate on the side bracket further increase the stability of the connection between the mounting bolts, the longitudinal beam and the side bracket.
