Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is based on and claims the priority to Chinese Patent Application No. 202310799065.6, filed on June 30, 2023, which is incorporated herein by reference in its entirety. TECHNICAL FIELD This application relates to the field of batteries, and specifically, to a battery installation frame, a frame assembly, and a vehicle. BACKGROUND Energy conservation and emission reduction are key to the sustainable development of the automotive industry. Electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important part of the sustainable development of the automotive industry. For electric vehicles, battery technology stands as a pivotal factor influencing their advancement. During the installation of batteries in vehicles, the space available for arranging the battery on the vehicle is limited, which leads to limited battery capacity and thus affects the driving range of the vehicle per battery swap. SUMMARY In view of the above issues, this application provides a battery installation frame, a frame assembly, and a vehicle, which can expand the battery mounting space, so as to increase the driving range of the vehicle per battery swap. According to a first aspect, this application provides a battery installation frame for installing a battery to a vehicle beam, where the battery installation frame includes a main body portion and an extension portion, where the main body portion is configured to be connected to the vehicle beam and extends along a length direction of the vehicle beam, the extension portion is at an angle to an extension direction of the main body portion and extends in a direction away from the main body portion, the extension portion is provided with a mounting structure, and the mounting structure is configured to mount the battery. In the technical solution of the embodiments of this application, since the length direction of the extension portion is at an angle to the extension direction of the main body portion and extends in the direction away from the main body portion, and the extension portion is provided with the mounting structure for mounting the battery, such a design can expand the battery mounting space in a width direction of the vehicle. This facilitates an increase in a dimension of the battery in the width direction of the vehicle, and also facilitates flexible arrangement of a distribution position, a quantity, and a structural form of the mounting structures on the extension portion, thereby improving the mounting strength of a large dimensional battery and increasing the driving range of the vehicle per battery swap. In some embodiments, the extension portion is provided in plurality on at least one side of the main body portion in a width direction of the main body portion, the plurality of extension portions are spaced apart along the extension direction of the main body portion, and a battery mounting space is defined between two adjacent extension portions.
