[0002] At present, in a new energy vehicle battery swapping station, the transportation of the battery is realized through a battery swapping platform. During the use of the battery swapping platform, if the running route of the battery swapping platform deviates, problems will occur in subsequent operations, including uneven placement of the battery in the battery compartment, the battery not reaching the correct position in the battery compartment, damage during battery picking and placing due to inaccurate position, and inability to complete the replacement due to inaccurate battery positioning. Therefore, a solution is needed to improve or solve the above problems. Summary of the Utility Model

The positioning component includes a measurement module, which is used to convert the position information of the positioning component into digital signals and feedback them. The positioning component is fixedly connected to the battery swapping platform.

[0005] Preferably, the stroke guiding component is fixed on a stationary body. The stroke guiding component includes a guiding groove and a chain placed therein. The positioning component includes a sprocket wheel cooperating with the chain.

[0006] Preferably, the positioning component further includes a connecting frame, a vertical reset module, and a horizontal reset module;

[0007] One end of the connecting frame is fixed on the battery swapping platform, and the other end is provided with a horizontal reset module and a vertical reset module;

[0008] The vertical reset module includes a vertically arranged guide rail 1, a slider 1 sliding on the guide rail 1, and a reset spring 1. The reset spring 1 always applies a force to the slider 1 to make it slide downward along the guide rail 1;

The sprocket wheel is installed on the horizontal reset module. The reset spring 2 always applies a force to the slider 2, and this force makes the sprocket wheel move in the direction perpendicular to the chain in the horizontal direction towards the position where the chain is arranged.

[0010] Preferably, a tensioning assembly for adjusting the tightness of the chain in the set direction is fixed on the guiding groove.

[0011] Preferably, one set of the tensioning assemblies is arranged at each of the two ends of the guiding groove.

[0014] The beneficial effects of the present utility model: In this solution, a travel guiding assembly is set to determine the standard path of the displacement of the battery swapping platform. During the operation of the battery swapping platform, whether the battery swapping platform reaches the standard position is determined through the position information collected by the measuring module, effectively ensuring the stable operation of the entire battery swapping process of the battery swapping station;

[0015] Among them, affected by the connection strength, connection accuracy, and friction between components of mechanical equipment, after the battery swapping platform has an operation deviation and then returns to the standard path, the sprocket cannot return to the standard path, resulting in a reduction in the measurement accuracy of the measuring module. Therefore, by setting a vertical reset module and a horizontal reset module, by applying an external force, the above-mentioned influence can be effectively reduced;

[0016] Among them, by setting the tensioning assembly, the tightness of the chain can be adjusted, further ensuring the operation accuracy of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
