Rolling shutter driving device and rolling shutter apparatus utilizing same

A rolling shutter driving device comprising:

• a gearbox;
• a motor comprising a stator and a rotor rotatable relative to the stator, the rotor comprising a rotary shaft connected to the gearbox, the rotary shaft of the motor being configured to drive through the gearbox a rolling shutter connected to one end of the gearbox;
• and
• a locking assembly comprising a brake pad circumferentially fixed relative to the stator and a rotary member circumferentially fixed relative to the rotary shaft, the rotary member being fixed relative to the rotary shaft, the brake pad being slidable axially relative to the rotary shaft between a locking position where the brake pad is engaged with the rotary member to lock the rotary shaft and hence hold the rolling shutter in position, and an unlocking position where the brake pad is disengaged from the rotary member to unlock the rotary shaft.
