the battery replacing arm 310 comprises a first telescopic structure 320 and a first lifting structure 330, the first telescopic structure 320 can realize bidirectional telescopic movement, that is, the first telescopic structure 320 can respectively extend and retract along the direction towards the main body 600 to be replaced and the direction towards the charging platform 500, so as to drive the battery 110 to move between the main body 600 to be replaced and the charging platform 500; the first lifting structure 330 is connected to the first telescopic structure 320, and is used for driving the battery 110 to perform lifting movement. It is easily understood that the battery 110 includes a low-charged battery and a full-charged battery, both of which have the same movement principle. In the battery replacing process, the battery 110 is moved in a manner that the battery 110 is lifted to a certain height by the first lifting structure 330 at the initial position, so that the battery 110 leaves the charging platform 500 or the main body 600 to be replaced, and then is translated by the first telescopic structure 320, and when the battery is translated to the upper side of the target position, the battery is lowered to the target position by the first lifting structure 330. If the insufficient battery on the main body 600 to be replaced is moved to the charging platform 500, the initial position is the battery 110 installation position of the main body 600 to be replaced, and the target position is the battery 110 placement position on the charging platform 500; if the fully charged battery on the charging platform 500 is moved to the main body 600 to be replaced, the initial position is a position for placing the battery 110 on the charging platform 500, and the target position is a position for installing the battery 110 on the main body 600 to be replaced.

It is easy to understand that when the second telescopic structure 340 only realizes the unidirectional telescopic movement, the battery replacement can be completed by means of the first rotating structure 360. If second extending structure 340 sets up the one side that is close to charging platform 500 at the robot main part, can realize through second extending structure 340 that battery 110 translates between robot main part and charging platform 500, drives the robot main part through first revolution mechanic 360 and rotates 180 degrees, and second extending structure 340 rotates to the robot main part and is close to the one side of treating the electricity main part 600 of trading, can realize that battery 110 translates between robot main part and the main part 600 of trading.

The second lifting structure 350 is lifted to separate from the deficient battery, and the battery replacing arm 310 is retracted again. The robot main body moves to the position corresponding to the fully charged battery on the charging platform 500 through the first rail 100, the battery replacing arm 310 stretches out to grab the fully charged battery, the connector and the positioning pin between the fully charged battery and the charging platform 500 are completely separated by lifting, the battery replacing arm 310 is retracted, the robot main body rotates 180 degrees through the first rotating structure 360 degrees, the robot main body moves to the position corresponding to the power-receiving heavy truck along the first rail 100, the battery replacing arm 310 stretches out to drive the fully charged battery to move to the position above the mounting position of the power-receiving heavy truck battery 110, the fully charged battery falls, so that the connector and the positioning pin are completely located, and the battery replacement is finished.

It should be understood that, if the battery replacing arm 310 adopts a bilateral telescopic manner, the battery replacing arm 310 may directly translate the power-deficient battery of the heavy-duty truck to the top of the charging platform 500, or directly translate the fully charged battery on the charging platform 500 to the top of the heavy-duty truck, and then move along the first track 100 after translation to perform alignment positioning, and implement the lifting motion of the battery 110 through the first lifting structure 330, without adopting the first rotating structure 360, and then complete the battery replacement.

In this embodiment, the battery swapping device includes a first battery swapping device 300 and a second battery swapping device 400, the first battery swapping device 300 and the second battery swapping device 400 have the same structure, the first battery swapping device 300 and the second battery swapping device 400 are respectively located on two sides of the charging platform 500, share the same charging platform 500, so that the occupied area is saved, the two battery swapping devices can operate simultaneously, the battery swapping operations are independently performed, the two battery swapping devices do not affect each other, and the service efficiency is higher.
