[0041] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS It should be understood that the specific embodiments described herein are intended to illustrate and explain the disclosure and is not intended to limit the disclosure.

[0042] In the present disclosure, in the case of not explained, the orientation, such as "upper, lower, left, right, top, before, before, after", it is generally based on the normal driving state of the vehicle. On the ground, when the vehicle is running normally, the direction of the vehicle ceiling is "top" or "upper", and the direction "bottom" or "under" toward the vehicle floor, the direction of the vehicle's left wheels is "left", and the right wheel towards the vehicle right wheel The direction is "right", heading toward the direction of the head is "prior", and the direction of the car is "post". In addition, "Internal, external" refers to the inside and outside of the contour of the corresponding structural component.

[0043] Refer Figure 1 to 8 As shown, the present disclosure provides a body structure, including the floor panel 1 and the first beam 2, the floor panel 1 and the first cross member 2 are arranged in front-rear direction and interconnected, the bottom surface of the floor panel 1 and the bottom surface of the first beam 2 flat. Here, the first cross member 2 is adjacent to the floor panel 1, and the first cross member 2 can be located on the front side of the floor panel 1, or may be located on the rear side of the bottom plate panel, the bottom of the floor panel 1 is used to arrange a battery pack (not shown). Since the bottom surface of the first cross member 2 is set to flush with the bottom surface of the floor panel 1, the first beam 2 can be avoided in the front-rear direction.

[0044] By the above technical solution, since the bottom surface of the first cross member 2 is flush, the first beam 2 cannot be mechanically interfered with the battery pack in the front-rear direction, thereby allowing the battery pack to extend in the front-rear direction, ie, The size in the front-rear direction can increase, thereby enabling the number of monomer batteries that can be arranged in the battery pack, and the battery life of the vehicle is effectively improved.
