By providing the body 6 with the mounting notch 61, and by configuring the battery pack 5 to constitute at least part of the floor of the body assembly 100, part of the floor of a conventional body can be omitted, so that the weight of the body 6 can be reduced, which is advantageous for the lightweight design of the vehicle, and for improving the range of the vehicle.

Along the length direction of the vehicle body main body 6 (i.e., the X direction shown in fig. 1), the dash panel 321 is located on the front side of the seal assembly 7, and the dash panel 621 is connected with the seal assembly 7 to form an annular structure. At least a portion of the seal assembly 7 is located between the body 6 and the battery pack 5. As some alternative embodiments of the present application, the seal assembly 7 is located between the body 6 and the battery pack 5. The seal assembly 7 can seal the gap between the vehicle body main body 6 and the battery pack 5.
