3) as shown in fig. 11, the direction of the second guide wheel 142 is adjusted by rotation, the second guide wheel 142 enters the inside of the rail 21 from the slot on the side of the rail 21, the direction of the second guide wheel 142 is adjusted by rotation, and the second guide wheel 142 is guided and rolled inside the rail 21;
4) as shown in fig. 12, the first guide wheel 141 is inserted into the rail 21 from the slit on the side surface of the rail 21 with the second guide wheel 142 as a fulcrum, and the direction of the first guide wheel 141 is rotationally adjusted, so that the 1 st guide wheel 141 rolls on the guide rail inside the rail 21;
at this time, as shown in fig. 13, the tension wheel 143 also contacts the outer lower surface of the rail 21, and presses both the first guide wheel 141 and the second guide wheel 142 against the inner rail of the rail 21;
because the heights of different tracks 21 are different, the length of the guide belt block 11 entering the track 21 is adapted to the height of the track 21, so as to prevent the upper wall of the track 21 from obstructing the extension of the action belt 131, as shown in fig. 12, 13 and 3, a through threaded hole is formed in the side surface of the interface flange 121b, the fastening block bolt 126 is matched with the threaded hole, the fastening block bolt 126 is screwed, the fastening block bolt 126 is tightly pressed on the side surface of the guide belt block 11, the guide belt block 11 is fixedly connected with the interface flange 121b, the fastening block bolt 126 is screwed, and the guide belt block 11 can be pulled up and down along the opening direction of the interface flange 121b for adjustment;

The principle and control method of the driver 1 for opening and closing a monorail double-open curtain,
as shown in figures 14 to 17 of the drawings,
the driver 1 is installed between the rolling units 22 near the moving end of any one curtain 23 (for convenience of expression, called a first curtain) at a certain distance from the moving end of the curtain, and preferably, the guide belt block 11 is located between the rolling units 22 at the outermost side and the next outer side of the moving end; the second end of the operating band 131 is fixed to the moving end of another curtain 23 (called the second curtain for convenience of expression) of the same track 21.
As shown in fig. 14 and fig. 15, when the driver 1 retracts the operating belt 131, the second end of the operating belt 131 pulls the second curtain to approach the first curtain, the forces are mutual, the operating belt 131 also pulls the first curtain to approach the second curtain, and finally the first curtain and the second curtain are closed, so as to close the two curtains 23 on the track 21. It should be noted that, the pulling forces applied to the first curtain and the second curtain are the same, but the moving resistances of the first curtain and the second curtain are different, and the movement of the first curtain and the second curtain may not be synchronous in the process, assuming that the moving resistance of the first curtain is greater than that of the second curtain, the second curtain moves first under the pulling of the driver 1, the pulling force is not enough to overcome the resistance of the moving end of the first curtain, the moving end of the first curtain remains stationary, and when the moving end of the second curtain moves to the middle of the track 21, the second curtain is hindered by the stationary end thereof and cannot move continuously, or as the number of the rolling units 22 of the second curtain increases, the moving resistance increases, the pulling force of the driver 1 increases, the moving resistance of the first curtain is overcome, the moving end of the first curtain starts to move, and finally; when the resistance of the first curtain motion is smaller than that of the second curtain, the principle is the same, and the description is omitted.
As shown in fig. 16 and 17, when the actuator 1 pushes the operation belt 131, the operation belt 131 has a certain width, and the gap between the operation belt 131 and the inner wall of the side surface of the rail 21 in the width direction is small, and the inner wall of the side surface of the rail 21 blocks the bending of the operation belt 131 in the width direction, so that the operation belt 131 is not bent in the width direction; the thickness of the action belt 131 is far smaller than the width, the two ends of the action belt 131 are squeezed, the action belt 131 can generate snake-shaped bending in the thickness direction, the upper side and the lower side of the bending are limited by the upper wall and the guide rail in the track 21, the curvature radius of the action belt 131 is not smaller than the height in the track 21, and therefore the two ends of the action belt 131 are squeezed and cannot be piled together, and the force for opening the curtain can be transmitted. It should be noted that, because the bending of the operating band 131 increases the resistance to contact with the inside of the track 21, a phenomenon that the first curtain and the second curtain move alternately may occur in the process, and assuming that the moving end of the first curtain moves to the fully opened state first and does not move any more, the operating band 131 continues to push the second curtain to move to the fully opened state, and finally the first curtain and the second curtain are fully opened.
In order to recognize the fully closed and fully open states of the window covering 23, and thus to control the actuator 1 to move,
according to the first scheme, the motor 125 is a direct current motor, the control device 15 controls the rotation direction of the motor 125 to roll up and push the action belt 131, when the curtain 23 is completely closed or completely opened, the curtain 23 moves to the limit position and cannot move continuously, the motor 125 is in a locked-rotor state, the control device 15 detects the current of the motor 125, and the current is compared with a preset locked-rotor current value, and the state that the curtain 23 is completely closed or completely opened is identified by combining the rotation direction of the motor 125.
In the second scheme, the motor 125 is a numerical control motor, and the control device 15 can accurately control the rotation angle of the motor 125, so that the winding and pushing lengths of the action belt 131 are indirectly controlled; the user initiates after the control device 15 has been installed,
1) the user moves the curtain 23 to the limit state, and the user informs the control device 15 of the state of the curtain 23 at the moment, wherein the informing mode can be manual input, software input, voice input and the like, and the control device 15 records the state;
2) the user moves the curtain 23 to another limit state, and the user informs the control device 15 of the state of the curtain 23 at the moment, wherein the informing mode can be manual input, software input, voice input and the like, and the control device 15 records the state; the controller knows the angle that the motor 125 is rotating when the two states are switched;
3) the control device 15 calculates the difference between the rotation angles of the corresponding motors 125 in the two extreme states;
4) the control device 15 controls the motor 125 to rotate according to the angle in step 2, so as to achieve the complete closing or the complete opening of the curtain 23.
The above is a concrete explanation of the structure and principle of the first embodiment, and in the practical application, the driver 1, the rail 21, the rolling unit 22 and the curtain 23 are developed and sold together, so that the workload of later-stage user installation is avoided.

The included angle between the first opening end face and the second opening end face of the guide belt block 11 is β, this included angle β satisfies that the second opening of the guide belt block 11 will not be obstructed by the upper wall inside the track 21 when guiding out the action belt 131, in order to make the action belt 131 move smoothly inside the guide belt block 11, the smaller the angle β angle is, the better, as long as the action belt 131 is not in 90-degree contact with the upper wall inside the track 21, there is a certain included angle, the upper wall inside the track 21 will also play a role in guiding the action belt 131, the angle β angle can be selected to be smaller than 90 degrees, preferably, within the range of 60 degrees to 90 degrees.
The driver 1 drives the curtain 23 to close and open through the rolling and pushing action belt 131, and the principle, the process and the control method are the same as those explained in the first embodiment, and are not described again.
