According to the present invention, the overall configuration is composed of an integrated control unit (1) folding aluminum rail portion (2) tension line pull portion (3) as shown in Figure 1 and the aluminum rail portion (2) Divide the rail into three and install the connecting part (4) consisting of connecting plate (23) in the middle to devise the structure to fold and unfold the aluminum rail.

In order to fold and unfold the aluminum rail, if there is a switch to detect an open / close in the middle of the rail, it becomes an obstacle, so the open / close detection device 147 is installed in the integrated controller unit 1 and the curtain fixed to the tension line 5 The ring 6 and 7 are detected when the opening and closing detection device 147 is pressed.

In the integrated controller unit 1, the electric control part used in the electric curtain is composed of a reverse rotation motor 11, a power transmission device, a jam detection device 148, a control circuit board 14, and an open / close detection device 147. Were all installed in an integrated controller

The power train has a motor gear 120, two middle gears 121 and 122, a middle gear fixing plate 123, and a tension to allow a user to open and close the curtain manually without a separate operation in case of power failure or failure. It is composed of line starvation 124

As illustrated in FIG. 2, the motor gear 120 is fixed to the shaft of the forward and reverse rotation motor 11, and the middle gear fixing plate 123 has two left and right middle gears 121 and 122. Assembled so as to rotate freely on the shaft, the center of the intermediate gear fixing plate 123 is fitted to the electric motor shaft, so that the two intermediate gears 121, 122 is engaged with the motor gear 120.

In addition, the tension wire gear 124 is assembled so as to rotate freely on a separate axis, and the tension wire 5 is connected to the tension wire pulley 125 at the bottom of the tension wire gear 124. ) Is configured to transmit power to the tension line (5) as it rotates.

To operate the electric curtain, if the electric motor 11 is rotated clockwise (assuming that the curtain is closed), the middle gear fixing plate 123 is rotated clockwise so that the middle gear 121 on the left side is a tension line. Meshes with starvation 124, causing the tension line 5 to move and the curtain hanging on the tension line 5 to close.

When the electric motor 11 is stopped while the curtain is closed, the tension wire gear 124 is turned clockwise when the user pushes it in the direction of closing the curtain, so that the tension wire 124 is the left middle gear 121. As the power transmission path between the motor gear 120 and the tension wire gear 124 is pulled out, the tension wire gear 124 can be freely rotated left and right, and the user can open and close the curtain manually. Become

You can switch manually in the same way with the curtain open.

The hook detecting device 148 is composed of two tensile wire pulleys 131 and 132, a disc shaped pulley 130, and an optical sensor 133, and a disc shaped pulley 130 between two tensile wire pulleys 131 and 132. ), The disc pulley 130 is rotated by the tension line 5 when the tension line 5 moves to the left and right.

The disc-shaped pulley 130 has a disc formed with holes to allow light to pass through at regular intervals, and an optical sensor 133 is installed with the disc interposed therebetween so that the disc-shaped pulley 130 rotates. Since the on / off signal is repeatedly generated at 133, the microcomputer 140 on the control circuit board 14 detects this signal and determines that the curtain is normally operating without jamming. When the microcomputer 140 detects a signal by contacting the open or closed pressing device 152 or 162 with 7, it is determined that the normal operation is completed, and the electric motor 11 is stopped.

However, if the on / off signal of the optical sensor 133 is not repeated while there is no signal from the open / close switches 15 and 16 while the electric motor 11 rotates, a curtain may be caught or a mechanical failure may occur. Judging that the microcomputer 140 to stop the electric motor 11 forcibly stopped by applying the jam detection device 148 to prevent the overload of the electric motor 11 or further mechanical failure in advance.

The control circuit board 14 is composed of a microcomputer 140, a wireless remote control receiver 141, a wired remote control receiver 142, a motor driver 143, a power supply unit 144, and the wired and wireless remote controllers 146 and 145. It is a main control unit which drives the electric motor 11 by receiving a signal such as an open / close / stop and stops the electric motor 11 by receiving the signals of the jam detection device 148 and the open / close detection device 147.

The open / close detection device 147 is composed of micro switches 15, 16, springs 151, 161, and pressing devices 152, 162, respectively, and is installed in the integrated controller 1 and is tensioned. The opening and closing switches 15 and 16 operate by pressing the pressing devices 152 and 162, which are fixed to the line 5 and moving along the aluminum rails 2, 7 and 7.

In order to operate the closing detection device, a separate curtain ring (7) fixed to the tension line (5) is installed in the middle of the aluminum rail so that the closing detection device can be pressed when the curtain is completely closed.
