Abstract:
1. A motor drive unit assembly for a motorized shade system having a covering material, the motor drive unit assembly comprising: a motor; a drive shaft that is operably connected to the motor such that the drive shaft rotates about a drive axis that extends along a first direction; an output member that is rotatable about the drive axis, such that rotation of the output member about the drive axis causes the covering material to move; a drag cup that includes a body, the drag cup defining a channel that extends into the body along the first direction; an input member that is disposed within the channel of the drag cup, the input member having a base that is configured to couple to the drive shaft and a body that extends from the base along the first direction, the body including a sidewall that defines a channel; a mandrel coupled to the output member and disposed within the channel of the input member body; and a spring disposed about the mandrel, wherein manual actuation of the output member causes the mandrel to rotate about the drive axis relative to the spring such that the output member is disengaged from the drive shaft, and wherein actuation of the drive shaft by the motor causes the input member to rotate relative to the drag cup such that the input member engages the spring to cause the spring to tighten about the mandrel to thereby impart rotation of the drive shaft to the output member.
