Description

CROSS-REFERENCE TO RELATED APPLICATION The present application claims priority to Chinese Patent Application No. 202321775824.7 filed on July 07, 2023 and entitled "BATTERY SWAPPING DEVICE AND BATTERY SWAPPING STATION", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD The present application relates to the field of batteries, and in particular, to a battery swapping device and a battery swapping station. BACKGROUND With the development of new energy technologies, batteries are widely used in electric devices, such as mobile phones, laptop computers, electric bicycles, electric vehicles, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, and electric tools. Limited by battery capacity, electric devices require frequent charging, which takes time and affects the user experience. SUMMARY The present application provides a battery swapping device and a battery swapping station, which can quickly swap a battery of an electric device. In a first aspect, the present application provides a battery swapping device. The battery swapping device includes a plurality of battery swapping platforms and a lifting mechanism. Each battery swapping platform is configured to disassemble and assemble a battery of an electric device. The lifting mechanism is connected to the plurality of battery swapping platforms and is configured to drive the plurality of battery swapping platforms to ascend or descend.
