  • Publication number: 20240360720
    Abstract: A cord divider is positioned on both sides of the cord winder of the control box of a cordless window curtain. Each cord divider is equipped with protrusions and crosspieces. When the cords are pulled out from the cord divider, the cords do not tangle or knot. The cords are wound up on the driving gear set, and the driving cord device prevents the cords from overlapping and causing uneven heights on both sides of the curtain. The use of cylinders in the cord dividers prevents excessive friction of the cords during use. There is no need to change the current cooperation way between the cords and the cord winder.

  • Publication number: 20220325577
    Abstract: A method for controlling curtain position of a curtain assembly includes a motor and a control unit. The motor includes a detection unit for detecting the working current of the motor. When the curtain moves upward and stops, the detection unit detects the working current increases. The detection unit sends a signal to a processor of the control unit to judge that the curtain reaches the upper-most position. Then the control unit stops the motor and demands the motor to operate reversely a range to lower the curtain slightly. The curtain that is lowered by operating the motor reversely is defined as at a limited position. When the curtain is lowered by the motor, the lower-most position of the curtain is defined by a pre-set number of revolutions of the motor. The pre-set number of revolutions of the motor is set by the control unit.
