Abstract
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.
Claims12
An electromagnetic clutch-controlled electric blind comprising:
- a blind body, said blind body having a headrail and a slat set, said headrail having an internal holding chamber, said slat set having a plurality of slats;
- a power drive, said power drive comprising only a single motor, and at least one first electromagnetic clutch controlled by a single receiver to actuate said first electromagnetic clutch between a first position engaged to said single motor and a second position disengaged from said single motor;
- an amplitude modulation set, said amplitude modulation set having a spindle engaged to said single motor for rotation with said single motor to lift/lower said slats to a desired elevation;
- a frequency modulation set, said frequency modulation set having a spindle engaged to said single motor through said first electromagnetic clutch when said first electromagnetic clutch is actuated to be in said first position to rotate and control a tilting angle of said slats.
