Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 202310802180.4, filed on June 30, 2023 and entitled "VEHICLE BODY AND VEHICLE", which is incorporated herein by reference in its entirety. TECHNICAL FIELD This application relates to the technical field of new energy vehicles, and more particularly, to a vehicle body and a vehicle. BACKGROUND New energy vehicles have become an important part of the sustainable development of the vehicle industry due to their energy-saving and environmentally friendly advantages. With the development of new energy vehicles, the demand for longer driving ranges has increased. To ensure that power consumption during vehicle operation can be promptly replenished, a solution of battery swapping to supplement power loss has emerged. For new energy vehicles, reducing battery swapping costs is a technical problem urgently needing resolution. SUMMARY This application provides a vehicle body and a vehicle, which can effectively reduce battery swapping costs. This application is implemented through the following technical solutions: According to a first aspect, this application provides a vehicle body, the vehicle body including: a bracket assembly, where the bracket assembly is provided with multiple groups of first mounting portions, each group of the first mounting portions being configured to detachably connect one battery; and multiple first connectors, the number of the first connectors being equal to the number of groups of the first mounting portions, each first connector being configured to connect with a second connector of one battery. In the above solution, the vehicle body includes a bracket assembly and multiple first connectors. By providing multiple first connectors and multiple groups of first mounting portions on the bracket assembly, the number of batteries to be replaced can be adjusted based on driving range requirements (that is, on-demand battery swapping; for example, when the required driving range is short, a smaller number of batteries can be mounted on a corresponding number of groups of the first mounting portions, with the second connector of each battery connected to a corresponding first connector; when the required driving range is long, a larger number of batteries can be mounted on a corresponding number of groups of the first mounting portions, with the second connector of each battery connected to a corresponding first connector), thereby saving the costs of additional batteries and effectively reducing battery swapping costs. According to some embodiments of this application, the bracket assembly includes a frame. In the above solution, the frame can serve as the main support of the vehicle body, capable of bearing various loads inside and outside the vehicle body. The frame can be provided with the first mounting portions, which, on the one hand, can stably support the batteries, improving the connection stability between the batteries and the vehicle body and reducing the risk of battery detachment; on the other hand, the frame is located at the bottom of the vehicle body, allowing batteries to be swapped from below the vehicle body. Compared to the current backpack-style battery swapping for heavy trucks (where batteries are mounted on the back of the cab), this changes the positional layout of the batteries in the vehicle body, effectively saving space in the longitudinal direction of the vehicle, thereby increasing the cargo capacity of the vehicle. According to some embodiments of this application, the bracket assembly further includes a bracket, the bracket being fixedly connected to the frame and the bracket being provided with the first mounting portions. In the above solution, by fixedly connecting the bracket to the frame, on the one hand, the impact on the structural reliability of the vehicle body due to the installation of the bracket can be reduced; on the other hand, the bracket can be stably disposed on the vehicle body to effectively support the batteries; furthermore, the bracket can be retrofitted onto the frame of existing vehicle bodies with low installation difficulty and high installation efficiency, enabling existing vehicles to quickly acquire on-demand battery swapping functionality. According to some embodiments of this application, the frame includes a first longitudinal beam and a second longitudinal beam, a highest point of the bracket being not higher than an upper end surface of the first longitudinal beam and a highest point of the bracket being not higher than an upper end surface of the second longitudinal beam. In the above solution, the frame may include the first longitudinal beam and the second longitudinal beam among main beams, for example, the frame may include the first longitudinal beam and the second longitudinal beam of main beams for large vehicles (such as heavy trucks). By disposing the bracket on the frame without protruding above the upper e
