Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application is a continuation of International Application No. PCT/CN2023/119836, filed on Sep. 19, 2023, which claims priority to Chinese Patent Application No. 202310798138.X filed on Jun. 30, 2023 and entitled “SUPPORT, SUPPORT ASSEMBLY, AND VEHICLE,” the entire content of each are incorporated herein by reference. TECHNICAL FIELD The present application relates to the technical field of new energy vehicles, and in particular to, a support, a support assembly, and a vehicle. BACKGROUND New energy vehicles have become an important part of the sustainable development in the vehicle industry due to their energy-saving and environmental protection advantages. With the development of the new energy vehicles, the requirement of people for the cruising range of the new energy vehicles is also increasing. In order to meet the needs of the new energy vehicles to replenish the power loss in time during driving, solutions for replenishing the power loss in time by battery swapping have emerged. For the new energy vehicles, how to improve the degree of weight reduction is a technical problem that needs to be solved urgently. SUMMARY The present application provides a support, a support assembly, and a vehicle. The technical solutions provided by the present application can improve the degree of weight reduction of the vehicle. The present application is implemented through the following technical solutions. In a first aspect, the present application provides a support, configured to be installed on a frame, where the support includes a mounting beam. The mounting beam is provided with a plurality of mounting portions, the plurality of mounting portions are arranged spaced apart in a length direction of the mounting beam, and the plurality of mounting portions are configured to be detachably connected to batteries. A cavity is formed inside the mounting beam, and the cavity extends in the length direction of the mounting beam. In the above solution, the support is configured to be installed on the frame of a vehicle, and the mounting portion on the mounting beam is configured to be detachably connected to the battery. By arranging the plurality of mounting portions spaced apart in the length direction of the mounting beam, it is possible to achieve modular battery swapping (that is, battery swapping on demand, for example, when the required cruising range is smaller, a smaller number of batteries can be installed on corresponding groups of mounting portions in the plurality of groups of mounting portions; when the required cruising range is larger, a larger number of batteries can be installed on corresponding groups of mounting portions in the plurality of groups of mounting portions) and/or increase locking points of the mounting beam and the battery to improve the locking strength. By forming the cavity inside the mounting beam, on the one hand, the support can be made lightweight, thereby improving the degree of weight reduction of the vehicle; on the other hand, since an extension direction of the cavity is consistent with an arrangement direction of the plurality of mounting portions, the influence of forming the cavity on the rigidity and strength of the support can be effectively reduced. Compared with the solution in which the cavity is formed inclined or perpendicular to the length direction of the mounting beam, the risk that due to impact, the support is bent or even broken along the location of the mounting portion can be reduced, so that the support has higher reliability under the condition of a high degree of weight reduction. According to some embodiments of the present application, the mounting portion includes a mounting hole formed in the mounting beam; the mounting hole penetrates through the mounting beam in a first direction, and the first direction is perpendicular to the length direction of the mounting beam. In the above solution, on the one hand, the mounting portion has a simple structure and thus is easy to manufacture; on the other hand, since the mounting portion has a simple structure, a connection method between the battery and the mounting portion is also simple, which can effectively improve the battery swapping efficiency; on the other hand, an extension direction of the cavity and a penetration direction of the mounting hole are perpendicular to each other, which can effectively reduce the influence of the cavity on the rigidity and strength of the support, so that the support has a higher structural strength to stably mount the battery, thereby improving the driving reliability of the vehicle. According to some embodiments of the present application, the mounting portion further includes a mounting sleeve, and at least a part of the mounting sleeve is arranged in the mounting hole. In the above solution, by arranging the mounting sleeve in the mounting hole, the structural strength of the mounting portion can be improved, so tha
