The invention provides a vehicle body structure for a battery-replaceable electric vehicle, and belongs to the field of vehicles. The vehicle body structure is of a bilateral symmetry structure. The vehicle body structure comprises a plurality of longitudinal beams and a plurality of cross beams. The longitudinal beams extend along the longitudinal direction of the vehicle, the plurality of longitudinal beams at least comprise two doorsill beams and two battery replacing longitudinal beams which are positioned on the left side and the right side of the vehicle, and middle channel side reinforcing beams which are positioned on the left side and the right side of a middle channel of the vehicle, each battery replacing longitudinal beam is connected with the corresponding doorsill beam, and the battery replacing longitudinal beams are used for mounting a battery pack. The multiple cross beams extend in the transverse direction of the vehicle and are in lap joint among the multiple longitudinal beams, and at least one cross beam is through in the transverse direction of the vehicle. According to the vehicle body structure, the battery pack can be protected from being extruded, and theproblem that the precision of a battery replacing plane is poor due to the fact that the battery replacing beam bodies are directly connected with other components through a welding process is solved.

    本发明提供了一种用于可换电电动车的车身结构,属于车辆领域。所述车身结构为左右对称结构,包括:沿车辆的纵向延伸的多根纵梁,所述多根纵梁中至少包括位于所述车辆左右两侧的两个门槛梁和两个换电纵梁以及位于所述车辆的中通道左右两侧的中通道侧加强梁,其中每一所述换电纵梁与每一所述门槛梁相连,所述换电纵梁用于安装电池包;和多根横梁,均沿所述车辆的横向延伸且搭接于所述多根纵梁之间,其中至少一个所述横梁沿所述车辆的横向贯通。本发明一个的车身结构能够保护电池包不被挤压,避免换电梁主体直接通过焊接工艺与其他部件连接而导致换电平面精度差的问题。
