3. The battery swapping connector protection device according to claim 2, characterized in that: There are two pull ropes, which are located on both sides of the battery swapping connector vehicle. The waterproof cover is unfolded by pulling the two pull ropes together.

4. The battery swapping connector protection device according to claim 1, characterized in that: The power unit includes two winch mechanisms located on both sides of the base; One of the hoisting mechanisms includes a motor I and a drum I. The drum I is rotatably supported on a base. The motor I is fixed on the base and connected to the drum I. The motor I drives the drum I to rotate. Another hoisting mechanism includes a motor II and a drum II. The drum II is rotatably supported on the base, and the motor II is fixed on the base and connected to the drum II. The motor II drives the drum II to rotate. One end of the waterproof shielding cloth is wound around roll I and the other end is wound around roll II. The waterproof shielding cloth has an opening at the position directly above the battery swapping connector vehicle end to expose the battery swapping connector vehicle end. Motor I is not powered on, while motor II is powered on and drives the drum to rotate, moving the opening on the waterproof cover away from the battery swapping connector vehicle end; Motor II is not powered on, while Motor I is powered on and drives the drum to rotate, bringing the opening on the waterproof cover cloth close to the end of the battery swapping connector vehicle.

5. A battery swapping connector protection device according to claim 1, characterized in that: The power components include separate pull ropes, winch mechanisms located on both sides of the base, and drums with power storage components; The drum is rotatably supported on the base, and the waterproof covering cloth is wrapped around the drum; The hoisting mechanism includes a motor and a rotating shaft. The rotating shaft is rotatably supported on the base. The motor is fixed on the base and connected to the rotating shaft. The motor drives the rotating shaft to rotate. One end of the pull rope is wound around the rotating shaft, and the other end is connected to the waterproof cover cloth. When the motor is powered on, it drives the rotating shaft to rotate, and the waterproof cover cloth on the drum is unfolded by pulling the rope. Without powering on the motor, the power storage component drives the drum to rotate, rewinding the unfolded waterproof tarpaulin back onto the drum.

6. A battery swapping connector protection device according to claim 5, characterized in that: There are two pull ropes, which are located on both sides of the battery swapping connector vehicle. The waterproof cover is unfolded by pulling the two pull ropes together.

7. A battery swapping connector protection device according to claim 1, characterized in that: The power components include a hoisting mechanism located on both sides of the base and a drum II with a power storage component; The drum II is rotatably supported on the base; The hoisting mechanism includes a motor and a drum I. The drum I is rotatably supported on the base. The motor is fixed on the base and connected to the drum I. The motor drives the drum I to rotate.
