Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is based on and claims the priority to Chinese Patent Application No. 202310799492.4, 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 development. However, when battery packs of vehicles are replaced at swapping stations, the energy in the battery packs is often not fully depleted, resulting in energy waste. SUMMARY In view of the above issues, this application provides a battery installation frame, a frame assembly, and a vehicle, where the battery installation frame is capable of mounting a plurality of batteries, allowing for selective replacement of batteries based on actual needs, thereby alleviating the problem of energy waste. According to a first aspect, this application provides a battery installation frame, where the battery installation frame includes a first frame, the first frame includes a plurality of extension portions spaced apart along a first direction and a plurality of battery mounting spaces arranged sequentially along the first direction, the battery mounting space is defined between two adjacent extension portions along the first direction, and the battery installation frame is provided with a battery mounting structure configured to mount a battery in the battery mounting space. In the technical solution of the embodiments of this application, when such a battery installation frame is configured to install batteries in a vehicle, since the battery installation frame includes a plurality of battery mounting spaces and the battery installation frame is provided with a battery mounting structure, each battery mounting space can be used for mounting a battery, and thus batteries can be individually mounted in each battery mounting space. This allows the battery installation frame to have the function of installing a plurality of batteries. During battery swapping, only batteries that have depleted their energy can be replaced while retaining batteries with remaining energy, thereby improving the energy utilization of the batteries and alleviating the problem of energy waste. Moreover, when the battery installation frame is used in a vehicle, the first direction can be set as the length direction of the vehicle, enabling the battery installation frame to have the function of mounting a plurality of batteries along the length direction of the vehicle. This helps to increase the quantity of batteries that can be arranged on the vehicle and helps to enlarge the dimension of the battery mounting space in the length and width directions of the vehicle to increase the volumetric energy density of the batteries. Additionally, since the battery mounting space is defined between two adjacent extension portions along the first direction, the extension portions can be used to protect the batteries, alleviating problems such as collisions and heat transfer between batteries in two adjacent battery mounting spaces along the first direction. In some embodiments, at least two of the battery mounting spaces on the first frame have consistent lengths in the first direction. In the above technical solution, since at least two of the battery mounting spaces on the first frame have consistent lengths in the first direction, batteries of the same specification can be installed in the at least two battery mounting spaces with consistent lengths in the first direction, allowing a battery to be installed in any one of these battery mounting spaces, thereby improving the installation efficiency and installation flexibility. In some embodiments, at least two of the battery mounting spaces on the first frame have inconsistent lengths in the first direction. In the above technical solution, since at least two of the battery mounting spaces on the first frame have inconsistent lengths in the first direction, when batteries of different specifications are installed in the at least two battery mounting spaces with inconsistent lengths in the first direction, batteries of different specifications can be installed in battery mounting spaces of corresponding dimensions. This enables the configurations of the battery mounting spaces to match the specifications of the corresponding batteries, thereby reducing installation space waste and allowing the battery installation frame to accommodate at least two types of batteries with different specifications. In some embodiments, the battery installation frame inc
