[0002] Currently, the definition of a battery swapping station usually refers to a centralized site for swapping batteries for four-wheel household vehicles. Affected by the scale of battery swapping, for battery swapping of two-wheel, three-wheel battery-powered vehicles or other light multi-wheel battery-powered vehicles in the market, a battery swapping cabinet is generally used for battery swapping, and the overall structure of the battery swapping cabinet is generally in the form shown in the appearance patent with the publication number CN308663430S.

[0003] Looking at the entire market of battery swapping cabinets for battery-powered vehicles, it can be seen that all the battery swapping cabinets are multi-compartment type (as shown in the above-mentioned published patent) distributed horizontally and vertically. Affected by the height that people can reach to replace the battery, within a limited usable area, the number of battery compartments in the battery swapping cabinet will remain within a relatively stable range. Affected by the above-mentioned various conditions, the battery cabinets are small and numerous in the current market distribution, which also poses a major challenge to the management of the battery swapping cabinets, such as various safety hazards mainly including fire protection problems. At the same time, based on the supporting services of the battery swapping cabinet, problems such as the municipal burden caused by line access and fire protection pipeline access also emerge.

[0004] Exploring the core issues discussed above, it can be obtained that limited by the height that can be reached by hand, the battery swapping cabinets in the market usually maintain a height of about 2m. Facing the market demand for the number of batteries that can be swapped, the existing form of the battery swapping cabinet is in a small and numerous distribution form or a form with a large horizontal floor area, which poses huge challenges to the management or land occupation cost of the battery swapping cabinet. Therefore, the present application proposes a new solution to solve or improve the above problems. Summary of the Invention

[0006] To achieve the above purpose, a technical solution adopted by the present invention is: a battery swapping station for battery-powered vehicles, including a cabinet body, wherein a charging rack, a battery replacement position and a transfer mechanism are arranged in the cabinet body;

[0007] The charging rack is provided with multiple layers, and each layer is provided with a plurality of battery charging positions;

[0008] A battery swapping window is opened on the cabinet body, the battery replacement position is located at the battery swapping window and is used for putting in / taking out the battery, and a cabinet door is arranged at the battery swapping window;

[0009] The transfer mechanism is used for transferring the battery between the battery charging position and the battery replacement position;

[0010] It further includes an intermediate conversion electric mechanism, which includes a rotating disk and a first driving assembly for driving the rotating disk to rotate. There are at least two battery replacement positions on the rotating disk, and the first driving assembly can drive the battery replacement positions on the rotating disk to sequentially pass through the power exchange window.

[0011] Preferably, the transfer mechanism includes an X-axis moving assembly, a Y-axis moving assembly, a Z-axis moving assembly, and a clamping assembly capable of clamping the battery;

[0012] The X-axis moving assembly is arranged on the Z-axis moving assembly and moves in the vertical direction with it.

The clamping assembly is placed on the first telescopic plate.

[0014] Preferably, the base plate is placed at the rotating end of a horizontal rotating assembly, and the horizontal rotating assembly moves with the X-axis moving assembly.

[0015] Preferably, a fire protection component is further arranged in the cabinet. The fire protection component includes a fire protection medium storage tank and a liquid / gas outlet pipe communicated with the fire protection medium storage tank. The liquid / gas outlet pipe passes through each battery charging position, and a plurality of nozzles are arranged on the liquid / gas outlet pipe, and at least one nozzle corresponds to one battery charging position.

[0016] Preferably, a fire protection box capable of loading hidden danger batteries is arranged in the cabinet, and the fire protection box is placed on the operation path of the clamping assembly on the transfer mechanism.

[0026] Among them, by setting up a fire protection box, batteries with potential safety hazards can be placed into the fire protection box through the transfer mechanism, further preventing the expansion of hazards.

[0027] Among them, by setting up battery charging ports at the battery replacement positions, the problem of reduced battery power due to long-term non-replacement can be avoided.

[0028] Among them, by setting up positioning codes and scanning devices, the replaced batteries can be recorded. At the same time, by setting the reading range of the scanning device and the positions of the positioning codes, the position of the transfer mechanism can be located, enabling it to smoothly place the batteries onto the battery charging positions.

[0029] Among them, by setting up appearance detection sensors, when the batteries enter the cabinet, batteries with potential safety hazards such as damaged appearance and liquid leakage can be identified and warnings can be issued. BRIEF DESCRIPTION OF THE DRAWINGS
