[0037] Optionally, the first moving mechanism 120 includes a track 123 and a first roller 121 arranged in the track 123. The first roller 121 is connected to the bottom of the battery swapping chamber 110. The track 123 can be arranged on the ground. The first roller 121 can move in the track 123 to drive the whole battery swapping chamber 110 to move, so that the position where the first battery compartment 111 or the second battery compartment 113 is located is aligned with the position where battery swapping is required. In this embodiment, the battery swapping chamber 110 is installed on a moving bottom plate 125, and the first roller 121 is installed on the side of the moving bottom plate 125 away from the battery swapping chamber 110. The first moving mechanism 120 can realize the overall movement of the battery swapping chamber 110, and can move the battery swapping chamber 110 to a place close to the charging platform 300, so that the fully charged battery 115 on the charging platform 300 corresponds to the position of the first battery compartment 111, so that the telescopic forklift 160 can directly extend to the fully charged battery 115 on the charging platform 300 and move the fully charged battery 115 into the first battery compartment 111; and, can move the battery swapping chamber 110 to a place close to the parking area, so that the discharged battery 115 on the vehicle corresponds to the position of the second battery compartment 113, so that the telescopic forklift 160 can directly extend to the discharged battery 115, move the discharged battery 115 out of the vehicle and retract it into the second battery compartment 113.

[0038] In this embodiment, the setting direction of the track 123 on the ground is consistent with the axial direction of the first lead screw 131, and the telescopic direction of the telescopic fork 160 is substantially perpendicular to the axial direction of the first lead screw 131.

[0039] In an alternative embodiment, the battery swapping device 100 further includes an angle adjustment mechanism 180. The angle adjustment mechanism 180 is connected to the battery swapping chamber 110 and is used to adjust the angular position of the battery swapping chamber 110, so as to finely adjust the swinging angle of the telescopic fork 160 during the battery swapping process. In this way, it can be applicable when there are slight deviations in the parking angle of the vehicle entering the position.

The arrangement of the second roller 185 can make the battery swapping chamber 110 rotate more smoothly and the angle adjustment efficiency higher during the process of rotating around the fixed shaft 181.

[0041] Please refer to Figure 3 and Figure 4 , it can be understood that if the parking position of the vehicle in the parking area is inconsistent with the preset position of the battery swapping chamber 110, it will cause the battery swapping position 210 on the vehicle not to correspond to the position of the battery 115 in the battery swapping chamber 110. For example, their axes are not parallel. If battery swapping is performed in a non-parallel state, it may be difficult for the telescopic fork 160 to pick up or place the battery 115, or the positioning is inconvenient or there are errors, etc.; in this case, the angle adjustment mechanism 180 can appropriately adjust the angular position of the battery swapping chamber 110 so that the position of the battery 115 in the battery swapping chamber 110 corresponds to the battery swapping position on the vehicle, which is beneficial to the positioning accuracy of the battery 115 picking and placing, the operation is more convenient, and it is beneficial to improve the battery swapping efficiency.

[0043] During battery swapping, first, the first moving mechanism 120 drives the entire battery swapping chamber 110 to move, aligning the first battery compartment 111 with the fully charged battery 115 on the charging platform 300. The grasping mechanism 140 moves above the first battery compartment 111 under the action of the second moving mechanism. The telescopic fork 160 extends towards the charging platform 300 side. The lifting unit 150 lowers the telescopic fork 160 so that the grasping unit 170 on the telescopic fork 160 is connected to the fully charged battery 115. The lifting unit 150 raises the telescopic fork 160 to lift the fully charged battery 115. The telescopic fork 160 retracts above the first battery compartment 111, and the lifting unit 150 lowers the telescopic fork 160 to deposit the fully charged battery 115 into the first battery compartment 111.

[0044] The first moving mechanism 120 drives the entire battery swapping chamber 110 to move, aligning the second battery compartment 113 with the vehicle battery swapping position 210 of the battery swapping vehicle 200. The grasping mechanism 140 moves above the second battery compartment 113 under the action of the second moving mechanism. The telescopic fork 160 extends towards the battery swapping vehicle 200 side.

The grasping mechanism 140 moves above the first battery compartment 111 under the action of the second moving mechanism. The lifting unit 150 lowers the telescopic fork 160, so that the grasping unit 170 on the telescopic fork 160 is connected to the fully charged battery 115 in the first battery compartment 111. The lifting unit 150 raises the telescopic fork 160 to lift the fully charged battery 115. The telescopic fork 160 extends towards the battery swapping vehicle 200 side. The lifting unit 150 lowers the telescopic fork 160 to place the fully charged battery 115 into the battery swapping position of the battery swapping vehicle 200. The lifting unit 150 raises the telescopic fork 160, and the telescopic fork 160 retracts above the second battery compartment 113, completing the vehicle battery swapping.

[0046] Similarly, the telescopic fork 160 can also move the discharged battery 115 in the second battery compartment 113 to the charging platform 300 for charging by the charging platform 300 under the combined action of the first moving mechanism 120, the second moving mechanism and the lifting unit 150. It is easy to understand that when placing the battery 115, it includes but is not limited to placing the battery 115 at a specified position on the battery swapping vehicle 200, the battery swapping chamber 110 or the charging platform 300. If there is a positioning error during the placement process, the angle adjustment mechanism 180 can be used for fine angle adjustment to adapt to different application scenarios.
