WINCH, AND AUTONOMOUS MOBILE APPARATUS COMPRISING SAME

摘要

Disclosed are a winch and an autonomous mobile apparatus comprising same. The winch comprises: a driving motor; a drum-driving shaft which rotates by means of the driving motor; a wire drum which rotates by means of the drum driving shaft; a roller-driving shaft which is arranged in parallel to the drum driving shaft, and which rotates in a direction other than the rotating direction of the drum-driving shaft by means of the driving motor; a roller which is connected to the roller-driving shaft, and which supports a wire being wound onto the wire drum or being unwound from the wire drum; and a one-way clutch installed on the roller-driving shaft to cut off the driving force transmitted by the roller-driving shaft to the roller when the wire drum rotates in the winding direction of the wire. The roller receives driving force by means of the roller-driving shaft, and rotates to enable the wire positioned between the wire drum and the roller to maintain tension force when the wire drum rotates in the unwinding direction of the wire.
