Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is based on and claims priority to Chinese Patent Application No. 202310798928.8, filed on June 30, 2023, which is incorporated into this application by reference in its entirety. TECHNICAL FIELD This application relates to the field of batteries, and more particularly, 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 advantages in energy efficiency and environmental friendliness, have become an important component of sustainable development in the automotive industry. For electric vehicles, the energy density of batteries affects the driving range per battery swap, which is beneficial for further improvement. SUMMARY In view of the above issues, this application provides a battery installation frame, a frame assembly, and a vehicle, capable of increasing the dimensional energy density of batteries, thereby improving the driving range per battery swap of the vehicle. According to a first aspect, this application provides a battery installation frame, where the battery installation frame includes a plurality of extension portions spaced apart, a battery mounting space running through along a height direction of the extension portions is formed between two adjacent extension portions, and the battery installation frame is provided with a battery mounting structure configured for mounting a battery in the battery mounting space. In the technical solution of the embodiments of this application, by configuring the battery mounting space to run through along the height direction of the extension portions, the space utilization of the battery in the height direction of the extension portions is improved, thereby increasing the dimension of the battery in the height direction of the extension portions, which is conducive to improving the dimensional energy density of the battery, thus enhancing the driving range per battery swap of the vehicle. Additionally, by providing the battery mounting structure, the efficiency of battery swap is improved. Furthermore, the battery mounting space runs through along the height direction of the extension portions, so that heat dissipation of the battery is facilitated, and the weight of the battery installation frame is reduced, thereby lowering the onboard burden of the battery installation frame. In some embodiments, the two extension portions defining the battery mounting space are spaced apart in a first direction and connected through a main body portion, the main body portion is located on one side of the extension portions in a second direction, and the first direction intersects with the second direction in a plane perpendicular to the height direction of the extension portions. In the above technical solution, the two adjacent extension portions are connected through the main body portion, making the structure of the battery installation frame simpler and easier to design, facilitating welding or integral molding. When the first direction is the length direction of the vehicle, the plurality of extension portions are spaced apart along the length direction of the vehicle, enabling full utilization of the space in the length direction of the vehicle to arrange more extension portions, thereby defining a greater number of battery mounting spaces to mount more batteries. This increases the battery dimension while also increasing the number of mounted batteries, enhancing the driving range per battery swap of the vehicle and reducing the frequency of battery swaps per unit mileage. In some embodiments, the two extension portions defining the battery mounting space are further connected through a reinforcing portion, and the reinforcing portion and the main body portion are disposed on both sides of the extension portions in the second direction. In the above technical solution, by providing the reinforcing portion, the two extension portions defining the battery mounting space are connected at both ends in the second direction through the main body portion and the reinforcing portion, respectively, forming a ring-shaped structure around the battery mounting space. This structure has higher strength and enhances the mounting reliability of the battery, providing more comprehensive protection to the battery from all sides and allowing flexible positioning of the battery mounting structure. In some embodiments, at least one of the main body portion, the extension portion, and the reinforcing portion is provided with the battery mounting structure. In the above technical solution, the battery mounting structure can be arranged on any one or more of the main body portion, the extension portion, and the reinforcing portion, making the positioning of the battery mounting structure more flexible. This facilitates setting the position of the battery mounting s
