The first lifting structure 330 is connected to the first telescopic structure 320 to drive the battery 110 to move up and down. It is easy to understand that the battery 110 includes a depleted battery and a fully charged battery, and their movement principles are the same. During the battery replacement process, the battery 110 moves by first rising to a certain height through the first lifting structure 330 at the starting position, so that the battery 110 leaves the charging platform 500 or the main body 600 to be replaced, and then moves through the first telescopic structure 320. When it is translated above the target position, it then descends to the target position through the first lifting structure 330 . If the depleted battery on the main body 600 to be replaced is moved to the charging platform 500, the starting position is the installation position of the battery 110 of the main body 600 to be replaced, and the target position is the placement position of the battery 110 on the charging platform 500; When the fully charged battery on the charging platform 500 moves to the main body 600 to be replaced, the starting position is the placement position of the battery 110 on the charging platform 500 and the target position is the installation position of the battery 110 on the main body 600 to be replaced.

The second telescopic structure 340 only realizes one-way telescopic movement, that is, the second telescopic structure 340 can move in a direction toward the main body 600 to be exchanged or toward the charging surface. The platform is telescopic in the direction of 500.

The robot body rotates 180° through the first rotation mechanism and moves through the first track 100 to a position corresponding to the empty position on the charging platform 500. The battery replacement arm 310 moves toward the charging platform 500 again. The second lifting structure 350 drives the depleted battery to fall until the depleted battery is placed in the empty position. The second lifting structure 350 rises and separates from the depleted battery, and the battery replacement arm 310 retracts again.
