Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is based on and claims the priority to Chinese Patent Application No. 202310799478.4, 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 advancement. During battery swapping operations for vehicles, not only is disassembly, replacement, and assembly of the battery required, but also the connection of electrical wires and pipelines between the battery and the vehicle, resulting in low swapping efficiency. SUMMARY In view of the above issues, this application provides a battery installation frame, a frame assembly, and a vehicle, which can improve the battery swapping efficiency and battery swapping success rate. According to a first aspect, this application provides a battery installation frame, including a frame body, a docking structure, and a mounting structure, where the frame body is configured to be installed to a vehicle body, the mounting structure is integrated on the frame body and configured to mount a battery, and the docking structure is also integrated on the frame body and configured to connect the vehicle body and dock with the battery, so as to enable the battery to form electrical and/or fluidic communication with the vehicle body. In the technical solution of the embodiments of this application, by integrating both the mounting structure and the docking structure on the frame body, when such a battery installation frame is used to install the battery to the vehicle body, the battery can be mounted and installed via the mounting structure integrated on the frame body, and the electrical and/or fluidic communication between the battery and the vehicle body can be achieved via the docking structure integrated on the frame body, thereby eliminating the need to connect electrical wires and pipelines, simplifying the complex battery swapping operation, and improving swapping efficiency. Moreover, since both the mounting structure and the docking structure are integrated on the frame body, a reference datum for the mounting position of the battery and a reference datum for the electrical/fluid docking position are consistent, that is, the frame body, thereby improving the battery swapping success rate. In some embodiments, the frame body includes a main body portion and an extension portion, where the main body portion is configured to be installed to the vehicle body, the docking structure is disposed on the main body portion, one end of the extension portion is connected to the main body portion, another end extends in a direction away from the main body portion, and the mounting structure is disposed on the extension portion. In the above technical solution, since the frame body includes the main body portion and the extension portion, with one end of the extension portion connected to the main body portion and the another end extending in the direction away from the main body portion, the docking structure and the mounting structure are respectively disposed on the main body portion and the extension portion, in other words, the docking structure and the mounting structure are disposed at different positions of the frame body, thereby avoiding mutual interference between the mounting structure and the docking structure, which helps to reduce the difficulty of coordinating the docking structure and the mounting structure with the battery 30. In some embodiments, the main body portion includes a beam avoidance groove, the beam avoidance groove has an opening running through along a first direction, and the docking structure is located within the beam avoidance groove. In the above technical solution, by providing the beam avoidance groove on the main body portion, when the main body portion is connected to the vehicle body, at least a portion of the vehicle beam can extend into the beam avoidance groove, making the connection between the main body portion and the vehicle body more compact. Additionally, by disposing the docking structure within the beam avoidance groove, the space within the beam avoidance groove can be fully utilized to improve space utilization and reduce the space occupied by the docking structure in other positions of the battery installation frame; the docking structure can be protected by the inner wall of the beam avoidance groove, thereby reducing the probability of the docking structure being damaged by collisions and alleviating the problem of corrosion f
