AUTOMATIC CURTAIN
Document Type and Number:
WIPO Patent Application WO/2021/047511
Kind Code:
A1
Abstract:
An automatic curtain comprises a curtain cloth (100), a folding/unfolding assembly (200), a transmission assembly (300), a forward and reverse rotating motor (400), a fixing assembly (500), and a roller assembly (600). Sliding blocks (220) are driven by a screw shaft (310) to move, so as to drive connecting rods (210) to move, and the connecting rods (210) drive a supporting rod (120) on the curtain cloth to move together, so that the curtain cloth (100) can be folded inwards or unfolded outwards to realize automatic lateral folding or unfolding of the curtain. Moreover, a gear transmission is arranged to transfer the motion to the screw shaft (310), and a torque required to be output by the forward and reverse rotating motor (400) can be reduced by changing a gear ratio, so as to realize an energy-saving effect. The whole curtain is fixed to a windowsill by means of an edge fixing plate (510), and the automatic curtain has the advantages of being low in energy consumption and convenient to mount and dismount.
