Abstract
A drive mechanism which is adapted for use with a swing device includes at least one electromagnetic driving unit and a control unit. The at least one electromagnetic driving unit is adapted to be pivotally connected to a bottom of the swing device. The control unit is electrically connected to the at least one electromagnetic driving unit for controlling the at least one electromagnetic driving unit to be activated and deactivated, so as to generate an intermittent magnetic force to drive swinging movement of the swing device. The swing device including the drive mechanism is also disclosed.
