It will further explain how to control the operation of the motorized curtain 1 via external wireless transmission, thereby effectively improving the problems disclosed in the prior art and further achieving the intended effects of the present invention.

[0071] First, please also refer to Figures 1 to 3 、 Figure 5 By utilizing the technical feature that the first transmission port 57 and the second transmission port 59 of the wireless control unit 50 accommodated in the accommodating portion 173 of the control device 17 are connected to the outside world, the transmission device 61 of the wireless remote control unit 60, which complies with the Wireless USB communication standard, is electrically plugged from the outside into the position corresponding to the first transmission port 57 or the second transmission port 59 of the wireless control unit 50 in the control device 17 of the upper beam 10.

[0073] Third, please also refer to Figures 1 to 5When the remote control device 63 of the wireless remote control unit 60 generates a folding signal, an extending signal, or a stop motion signal, the signal is electrically transmitted to the microprocessor 51 through the transmission device 61 and the corresponding first transmission port 57 or second transmission port 59 of the wireless control unit 50.

Then it is tied and fixed to the lower beam 40A, so that the multiple blades 31A of the curtain body 30A and the lower beam 40A can be affected by the rotation of the two rope-winding devices 15A and accordingly present movement states such as upward folding, downward unfolding or stopping; and any flip component 70A is basically composed of a flip part 71A and two flip ropes 73A tied to the flip part 71A. The flip parts 71A of any flip component 70A are respectively arranged on one side of the two rope-winding devices 15A and are all sequentially passed through the rotating rod 11A of the upper beam 10A in the same direction, so that the flip part 71A of any flip component 70A can also be affected by the pivoting of components such as the rotating rod 11A of the upper beam 10A, the pivot part 13A and the rope-winding device 15A to produce a flipping movement in the clockwise direction or counterclockwise direction. In addition, the electric curtain 1A disclosed in this embodiment is mainly achieved by the following technical features: one end of the two flip ropes 73A of any flip component 70A is respectively tied to the opposite sides of the flip part 71A and moves accordingly due to the pivoting of the two rope winding devices 15A, and the other end of the two flip ropes 73A of any flip component 70A is respectively passed through the two rope passing holes 101A of the upper beam 10A and connected to the multiple blades 31A of the curtain body 30A and fixed to the lower beam 40A.
