Automatic battery replacement apparatus, moving platform, and rechargeable battery

An automatic battery replacement apparatus, comprising:

• a movable carrier including:
• a carrying body having a power supply slot recessed in an outer surface thereof, wherein an inner lateral wall of the power supply slot is in a shape of an arc having a central angle that is less than or equal to 180 degrees;
• and
• a moving component assembled to the carrying body and configured to move on a working surface;
• a charging station configured to be located at a predetermined position, wherein the charging station has a charging slot recessed in an outer surface thereof, and an inner lateral wall of the charging slot is in a shape of an arc having a central angle that is less than or equal to 180 degrees;
• and
• a battery replacement module including:
• a driving gear assembled to at least one of the movable carrier and the charging station and configured to be driven by electricity supplied from the charging station;
• and
• two rechargeable batteries each having a matching structure that is configured to be engaged with the driving gear, wherein one of the two rechargeable batteries is assembled in the power supply slot for supplying electricity to the movable carrier, and another one of the two rechargeable batteries is assembled in the charging slot, and wherein the movable carrier and the rechargeable battery assembled therein are jointly defined as a moving platform, and the moving platform is configured to be in a movement operation mode where the moving platform is capable of motion relative to the charging station, or a stationary battery replacement mode where the moving platform is stationary relative to the charging station;
• wherein, when the moving platform is in the stationary battery replacement mode, a center of circle of the inner lateral wall of the power supply slot is overlapped with a center of circle of the inner lateral wall of the charging slot and defines a rotation axis, and the driving gear is engaged with the matching structure of at least one of the two rechargeable batteries so as to rotate the rechargeable batteries along the rotation axis until positions of the two rechargeable batteries are interchanged with each other.
