Battery swap apparatus and battery swap system

A battery swap apparatus for swapping a battery of an electrical device comprising:

• a floating platform;
• a locking and unlocking mechanism, arranged on the floating platform and configured to lock the battery to the electrical device or to unlock the battery from the electrical device;
• and
• a positioning mechanism, arranged on the floating platform and configured to position the floating platform relative to the electrical device;
• the positioning mechanism comprises a positioning member and a driving member, the driving member being configured to drive the positioning member to move in a height direction of the battery swap apparatus, so as to adjust the height of the positioning member;
• the positioning mechanism comprises a transmission assembly, and the driving member is in transmission connection with the positioning member via the transmission assembly;
• and
• the transmission assembly is configured to convert a rotation of an output end of the driving member into a linear movement of the positioning member;
• and
• the transmission assembly comprises a first gear, a second gear and a lead screw, the first gear meshes with the second gear, the first gear is connected to the output end of the driving member, the second gear is sleeved on the lead screw and threadedly connected to the lead screw, and the positioning member is connected to the lead screw;
• and
• a rotation axis of the first gear, a rotation axis of the second gear and an axis of the lead screw are all consistent with the height direction of the battery swap apparatus.
