[0032] like Figures 8 to 13 As shown, the curtain system also includes a cover shell 25, both ends of the cover shell 25 are fixed with brackets 26, and the brackets 26 are provided with clamping columns 27.

The limit point set by the motor is easy to be lost when the power is exhausted, especially the motor of the power-connected model has a built-in backup battery to maintain the existence of the limit point.

[0034] like Figure 3 to Figure 4 As shown, the Hall sensor unit 13 includes a first Hall sensor and a second Hall sensor, and the first Hall sensor and the second Hall sensor are fixed at different positions beside the magnetic ring 8. The first Hall sensor and the second Hall sensor are arranged at different positions, and are used to detect the direction of rotation of the magnetic ring 8. According to the different phases sensed by the first Hall sensor and the second Hall sensor, the rotation direction of the magnetic ring 8 is judged. The first Hall sensor and the second Hall sensor transmit the sensed phase to the controller, and the controller drives the motor to rotate clockwise or counterclockwise according to the phase situation.

[0035] In this embodiment, the output revolution speed of the motor 9 is N1, the output revolution speed of the speed reducer 10 is N2, and the speed ratio of the motor to the speed reducer is N1 / N2. Among them, N1 < N2. When the variation of the runner 12 is n turns, the variation of the rotating shaft of the motor 9 is n*N2 / N1. The variation of the rotating shaft of the motor 9 is greater than that of the runner 12, and the rotating shaft of the motor has good sensitivity.

[0036] The power supply 6 is a lithium battery. A controller is also provided on the circuit board 7. The drive motor 9 and the Hall sensing unit 13 are both electrically connected to the controller, and the controller is a single-chip microcomputer.

[0037] The system also includes a remote controller, and the remote controller is wirelessly communicatively connected to the circuit board 7.

[0038] The specific working process of the flashlight integrated curtain system is as follows: When it is necessary to lower the curtain, manually pull the lower beam 1, and the lower beam 1 drives the reel 4 to rotate through the curtain fabric. As Figure 1 shown, if the curtain fabric is manually pulled downward, when looking from the Figure 1 right side, the reel 4 rotates clockwise. When the reel 4 rotates clockwise, the runner 12 and the support rod 17 inside the reel 4 will be driven to rotate clockwise at the same time. The clockwise rotation of the support rod 17 causes the torsion spring 19 to start storing energy, as Figure 6 shown; while the clockwise rotation of the runner 12 causes the speed reducer 10 to start rotating clockwise. The rotation of the speed reducer 10 drives the rotating shaft of the motor 9 to start rotating clockwise. While the rotating shaft 9 rotates clockwise, it will drive the magnetic ring 8 on the rotating shaft to rotate clockwise. The Hall sensing unit 13 senses the clockwise rotation of the magnetic ring 8, and then transmits the sensed electrical signal to the controller through the circuit board 7. The controller thus drives the motor 9 to start, and after starting, the rotating shaft of the motor 9 rotates clockwise. The rotating shaft of the motor 9 drives the runner 12 to rotate clockwise through the speed reducer 10. At this time, the runner 12 drives the reel 4 to rotate clockwise. At this time, without manual pulling down, the curtain fabric starts to descend under the drive of the motor 12.

[0039] During the process of the motor 12 starting to rotate, the torsion spring 19 on the support rod 17 further stores energy. When the curtain descends to the limit point, at this time, the resultant force of the energy stored in the torsion spring and the torque of the motor shaft is equal to the resultant force of the gravity of the curtain and the gravity of the lower beam. At this time, the force reaches balance, and the curtain hovers at the lower limit point.

[0040] During the process of the curtain descending, the Hall sensing unit records the number of turns of the motor shaft rotation. A preset number of turns value when reaching the lower limit point of the curtain is pre-stored in the controller. When the number of turns of the motor rotation is equal to the preset number of turns value, the controller drives the motor to stop rotating.

[0041] When the curtain needs to be pulled up, the lower beam 1 is manually lifted up. As the lower beam 1 is lifted up, the gravity of the lower beam disappears, and the force balance is broken. At this time, the stored force in the torsion spring 19 begins to be released, and the torsion spring 19 drives the rotating wheel 12 to rotate, Figure 1 Looking from the right side, the rotating wheel 12 rotates counterclockwise, and the rotating wheel 12 rotates counterclockwise and drives the rolling tube 4 to rotate counterclockwise at the same time, so that the rolling tube 4 starts to roll up the curtain cloth to pull up the curtain.

[0042] When the wheel 12 rotates counterclockwise, the reducer 10 and the shaft of the motor 9 rotate counterclockwise at the same time. The shaft of the motor 9 rotates counterclockwise, driving the magnetic ring 8 on the shaft to rotate counterclockwise at the same time. When the Hall sensor unit 13 detects that the magnetic ring rotates counterclockwise, the induced electrical signal is transmitted to the controller through the circuit board 7. The controller drives the motor 9 to start, and at this time, the shaft of the motor 9 rotates counterclockwise.

[0043] The shaft of the motor 9 rotates counterclockwise, driving the reducer 10 and the rotating wheel 12 to rotate counterclockwise at the same time. When the rotating wheel 12 rotates counterclockwise, the torsion spring 19 further releases the stored force. Under the action of the rotating wheel 12 and the torsion spring 19, the rolling tube 4 accelerates to rotate counterclockwise, thereby achieving the effect of quickly rolling up the curtain fabric 2, that is, realizing the rapid retraction of the curtain.

[0044] The present invention discloses an intelligent dual-drive curtain system including a roller tube, wherein curtain fabric is wound on the roller tube, wherein a lower beam is fixed at one end of the curtain fabric, wherein a tubular motor and a spring rod driving unit are arranged in the roller tube, wherein during operation, the lower beam of the curtain is lightly pulled to break a suspended state of the curtain, and the lower beam drives the fabric and the roller tube to rotate, triggering a motor wheel in the roller tube to rotate and start the motor, thereby realizing automatic unfolding of the curtain to a limit point, and when the curtain needs to be retracted, only the lower beam needs to be pushed, and the spring driving force breaks the suspended state of the curtain due to the force of pushing the lower beam upward, and the spring driving force is greater than the torque of the motor, driving the roller tube to rotate, triggering a motor wheel in the roller tube to rotate and start the motor, thereby realizing automatic retraction of the curtain to a limit point driven by the motor, thereby improving the retraction and unfolding speed of the curtain and providing a better experience.

[0045] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
