The battery pack of new energy vehicles is generally located at the bottom of the middle of the vehicle, under the front floor. In the vehicle chassis structure, especially the frame structure near the battery pack, it not only bears the weight of the battery pack and protects the battery pack, but also is an important supporting structure of the vehicle. It needs to bear the main weight of the vehicle body and also has to have anti-collision strength to reduce the risk of side collisions from the vehicle.

In the existing vehicle body structure, when the vehicle collides, the battery pack is easily squeezed and collided, causing the risk of fire due to unreasonable structural design. Therefore, it is urgent to design a vehicle body structure that can reduce the risk of fire caused by squeezing and collision of the battery pack when the vehicle collides with a large collision.
