Embodiment Construction

[0048] figure 1 is a structural schematic diagram of a vehicle body structure according to an embodiment of the present invention. figure 1 In the middle, X direction is the longitudinal direction of the vehicle, Y is the lateral direction of the vehicle, +X is the rear side of the vehicle, and +Y is the right side of the vehicle. Such as figure 1 As shown, the present invention provides a vehicle body structure for a swappable electric vehicle. The vehicle body structure is a left-right symmetrical structure and includes multiple longitudinal beams and multiple cross beams. A plurality of longitudinal beams extend longitudinally along the vehicle, and the plurality of longitudinal beams at least include two sill beams 4 located on the left and right sides of the vehicle, two battery replacement longitudinal beams 5 and central channel side reinforcement beams located on the left and right sides of the central channel of the vehicle 2. Each battery-replacing longitudinal bea...

Abstract

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.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a vehicle body structure for a switchable electric vehicle. Background technique [0002] In recent years, with the depletion of global oil resources, air pollution has become more and more serious, which has had an impact that cannot be ignored on the sustainable development of human society. The research and application of electric vehicles with the goals of energy saving, environmental protection and safety has become the focus and inevitable choice of the development of the automobile industry. Pure electric vehicles usually have two modes of charging and battery swapping. The battery swapping mode is popular because it takes less time to swap batteries and does not need to wait for a long time for the battery to be fully charged. [0003] Compared with traditional vehicles, the electric vehicle body cannot arrange additional beams or longitudinal beams to improve the performance of ...
