Problems solved by technology
For some installed artificially driven blackout roller blinds, electric automatic control can be realized by adding an electric drive device to them, but because the manufacturer of the electric drive device cannot predict the existing installation conditions of various roller blinds, such as the thickness of the curtain surface and length, the transmission or the like that may be present in the roller shutter box, and the electric drive is usually installed in a recess in the wall, and it is impossible to monitor the winding of the belt inside. In this case, the maximum permissible winding capacity of the electric drive winder may be exceeded before the end position is adjusted, causing damage to or even destruction of the tape cassette containing the belt and the entire drive

Embodiment 1
[0023] This example is provided with housing 14, and the drive motor 9 is housed in the lower part of the housing cavity, and the output shaft of the motor is connected with the winder 18 through the drive gear set. On the moving guide wheel 6, turn an angle and stick on the guide wheel 5 to change direction and stretch out from the housing 14, and the control circuit board 11 of the motor is also contained in the housing.
[0024] The structure of the driving gear set is as follows: the motor 9 meshes with the third gear worm wheel 3 through the worm 8 on the output shaft, the third gear 3 meshes with the second gear 2 through the coaxial pinion, and the second gear meshes with the second gear through the first gear. The gear 7 of the winding machine is connected in transmission, and the rotating shaft of the winding machine 18 coaxial with the gear 7 rotates synchronously with the gear 7.
[0025]In the housing 14, a driven speed sensor 16 and a driving speed sensor 15 are r...

The present invention relates to a method and apparatus of a coiling type window shade, belt which is used for driving the window shade is coiled on the tape coiling machine, the electrical machine drives tape coiling machine running by driving gear group, and the driven leading sheave (5, 6) driven by belt is supposed, the terminal rotate speed rate (DM) is carried out and stored in memorizer when the coiling belt radius of the tape coiling machine is the maximum permissible value between the tape coiling machine and the driven guide wheel; in the running process of tape coiling machine, the rotate speed rate (D) between the tape coiling machine and the driven guide wheel is determined by using a rotational speed sensor, the real-time rotate speed rate (D) is inputted into the comparator and is compared with the terminal rotate speed rate (DM), when the real-time rotate speed rate (D) is equal to the terminal rotate speed rate (DM), the control signal for breaking the driving electrical machine is sent. The present invention is suitable for mounting various shade curtains with different length and thickness, can effective avoiding the situation of overload coil capacity and ensure device safe.
Description
technical field [0001] The invention belongs to a driving device capable of opening and closing a shading object, in particular a driving device for a winding type shading curtain. Background technique [0002] Blackout curtains such as roll-up blinds, roller blinds or sheet curtains are usually wound on a reel, and the reel is driven by a belt wound on a winder driven by a manual drive or by a motor, so as to realize opening or lowering of the shade. For some installed artificially driven blackout roller blinds, electric automatic control can be realized by adding an electric drive device to them, but because the manufacturer of the electric drive device cannot predict the existing installation conditions of various roller blinds, such as the thickness of the curtain surface and length, the transmission or the like that may be present in the roller shutter box, and the electric drive is usually installed in a recess in the wall, and it is impossible to monitor the winding o...
