An electromagnetic clutch-controlled electric blind is constructed to include a blind body formed of a headrail defining a receiving chamber, a set of slats, and a bottom rail, a power drive, the power drive including a reversible motor and electromagnetic clutch apparatus connectable to the motor, an amplitude modulation set coupled to the motor for rotation with the motor to lift/lower the slats to the desired elevation, a frequency modulation set coupled to the motor through the electromagnetic clutch apparatus and adapted for controlling tilting angle of the slats.

Electromagnetic clutch-controlled electric blind

A screw transmission mechanism for a motor-driven blind is constructed to include a driving unit, and at least one cord roll-up unit controlled by the driving unit to lift/lower or tilt the slats of the motor-driven Venetian blind. Each cord roll-up unit includes an amplitude modulation set controlled by the driving unit to lift/lower the slats and bottom rail of the Venetian blind, a frequency modulation set for rotation with the amplitude modulation set to tilt the slats of the Venetian blind, and a linkage adapted to control connection between the frequency modulation set and the amplitude modulation set.

Screw transmission mechanism for a blind

A friction transmission mechanism for a motor-driven blind is constructed to include a driving unit, and at least one cord roll-up unit controlled to the driving unit to lift/lower or tilt the slats of the motor-driven Venetian blind. Each cord roll-up unit includes an amplitude modulation wheel controlled by the driving unit to lift/lower the slats and bottom rail of the Venetian blind, a frequency modulation wheel for rotation with the amplitude modulation set to tilt the slats of the Venetian blind, spring elements, which forces the frequency modulation wheel into friction-engagement with the amplitude modulation wheel, and a support supporting the amplitude modulation wheel, the support having a shoulder adapted to act with a protruding block of the frequency modulation wheel and to further limit angle of rotation of the frequency modulation wheel.

Friction transmission mechanism for a motor-driven blind

A plug-in transmission mechanism for a motor-driven blind is constructed to include a driving unit, two cord roll-up units controlled by the driving unit to lift/lower or tilt the slats of the motor-driven Venetian blind. Each cord roll-up unit includes an amplitude modulation wheel rotated by the driving unit to lift/lower the slats and bottom rail of the Venetian blind, a frequency modulation wheel for rotation with the amplitude modulation wheel to tilt the slats of the Venetian blind, a stop block adapted to limit the angle of rotation of the frequency modulation wheel, and a link supported on a spring in a longitudinal groove of the amplitude modulation wheel and detachably engaged into a notch of the frequency modulation wheel to control linkage between the amplitude modulation wheel and the frequency modulation wheel.
