Abstract
A drone loading/unloading device includes an electric reel selectively movable for releasing/winding a cable adapted to be wound around the electric reel. A driver is operably connected to the electric reel to selectively drive the electric reel to reciprocally move from a locked position and an unlocked position and a buffer is mounted between the driver and the electric reel such that buffering effect is provided to the electric reel when moved from an unlocked position to a locked position.

A drone loading/unloading device comprising:
- an reel selectively movable for releasing/winding a cable adapted to be wound around the electric reel;
- a driver operably connected to the electric reel to selectively drive the reel to reciprocally move from a locked position and an unlocked position;
- and
- a second driver selectively connected to the reel to drive the reel to move linearly to optionally position the reel at the first position to allow the reel to engage with the driver and at the second position to allow the reel to release the cable;
- and
- a buffer mounted between the second driver and the reel to provide buffering effect to the electric reel when moved from an unlocked position to a locked position, wherein the reel is movably positioned between a first position where the driver drives the reel to retrieve the cable and a second position where the reel is disengaged with the driver to allow the reel to rotate freely so as to release the cable.
