Problems solved by technology
[0003] In the prior art, the battery pack is usually arranged under the floor panel of the vehicle, its upper size is limited by the floor panel, and its lower size is limited by the passability of the vehicle (that is, the minimum ground clearance required by the vehicle) ), its front size is limited by the front sub-frame, and its rear size is limited by structures such as the rear motor. That is to say, the overall size of the battery pack cannot be increased, so that The number is limited, and the battery life of the vehicle cannot be improved

Embodiment Construction
[0041] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0042] In this disclosure, unless stated otherwise, the orientation words used such as "up, down, left, right, top, bottom, front, rear" are usually relative to the normal driving state of the vehicle, specifically Generally speaking, when the vehicle is running normally, the direction towards the vehicle roof is "top" or "up", the direction towards the vehicle floor is "bottom" or "down", the direction towards the left wheel of the vehicle is "left", and the direction towards the right wheel of the vehicle is "left". The direction of the vehicle is "right", the direction towards the front of the vehicle is "front", and the direction towards the rear is "rear...

The present disclosure relates to a vehicle body structure and a vehicle. The vehicle body structure includes a floor panel (1) and a first beam (2). The floor panel (1) and the first beam (2) are arranged in the front and rear direction and connected to each other. , the bottom surface of the floor panel (1) is flush with the bottom surface of the first beam (2). Through the above technical solution, since the bottom surface of the first cross beam is flush with the bottom surface of the floor panel, the first cross beam cannot mechanically interfere with the battery pack in the front-rear direction, thereby allowing the battery pack to extend in the front-rear direction, that is, in the front-rear direction. The size can be increased, thereby increasing the number of single cells that can be arranged in the battery pack, and the vehicle's endurance is effectively improved.
Description
technical field [0001] The present disclosure relates to the technical field of vehicle manufacturing, and in particular, to a vehicle body structure and a vehicle using the vehicle body structure. Background technique [0002] With the increasingly prominent energy issues and environmental issues, pure electric vehicles with less impact on the environment are becoming more and more popular. The power of pure electric vehicles comes from the battery pack. The number of single cells in the battery pack determines the endurance of the vehicle. The more the number of single cells, the better the endurance of the vehicle. [0003] In the prior art, the battery pack is usually arranged under the floor panel of the vehicle, its upper size is limited by the floor panel, and its lower size is limited by the passability of the vehicle (that is, the minimum ground clearance required by the vehicle) ), its front size is limited by the front sub-frame, and its rear size is limited by s...
