The technical solution of the present invention is understood by the working conditions of the present invention.
The number of the blades is determined according to the height size of the louver, and the bearing bushes with the same number as the blades are uniformly distributed in the grooves on the two sides of the window frame and are fixed. A bearing is embedded in the bearing bush, an elastic connecting part, also called a spring support arm, is arranged on the bearing, and a gear is arranged on the other side of the bearing; an openable clamp is arranged on the spring support arm, the blade is horizontally clamped into a clamp notch, and two ends of the blade are respectively provided with a hole and a lead screw is inserted into the holes; one end of the screw rod is connected with the transmission device or the motor, and the supporting sheet is fixedly connected after penetrating into the screw rod.
The folding condition of the shutter blades:
the retractable motor is started in the forward direction to drive the lead screw to rotate in the forward direction, the supporting sheet moves upwards through the thread of the lead screw, the elastic force of the elastic connecting part is gradually overcome by the supporting sheet along the lower waist of the trapezoidal boss, the trapezoidal boss is gradually expanded, the blades are pushed to lift, and the like until all the blades are overlapped one by one and moved to the top of the shutter, and at the moment, all the blades are folded in, so that the shutter is in a completely opened ventilation state.
And (3) releasing of the shutter blades:

The blades move downwards under the action of self weight without the support of the supporting sheet. In the whole downward moving process of the blade, the blades are overlapped one by one, when the blades are together, the first blade (namely the lowermost blade) reaches the notch of the trapezoidal boss of the first fixture, and the blades can still overcome the elasticity to enable the trapezoidal boss of the fixture to be in an expanded state due to the fact that the blades are arranged on the blade, so that the first blade cannot be clamped by the notch of the trapezoidal boss of the first fixture. Only when the last blade (i.e. the uppermost blade) descends to the notch of the trapezoidal boss of the fixture, no blade on the notch overcomes the elastic force, so that the trapezoidal boss of the fixture is closed under the action of the spring to clamp the last blade in the notch. After the uppermost blade is clamped by the notch, the blade below the uppermost blade becomes the last blade, then the above process is repeated, and the rest is repeated until each blade is respectively clamped into the corresponding fixture trapezoidal boss notch, and at the moment, the shutter is in a semi-closed ventilation and sunshade state.
Rotation condition of the louver blades:
the rotating motor is started in the forward direction to drive the gear of the transmission device, the gear enables the bearing of the rotating device to rotate, and the bearing drives the clamping device and the blade clamped into the notch of the clamping device to rotate. The motor can be divided into a plurality of gears according to time or angle: the louver is in a semi-closed state of completely closing and not ventilating or ventilating and lighting by controlling the rotation of the blades to reach an ideal inclination angle through the motor according to the ventilation or light transmission degree of the blades at 20 degrees, 30 degrees, 45 degrees and 90 degrees.
And starting the rotating motor reversely to reset the inclined blades after rotation and restore to the horizontal state.
The following describes a method for controlling a blind according to the present invention, including the following two points:
firstly, the rotating motor and the retracting motor are connected with a power supply through a single-pole double-throw switch or a semiconductor device or an integrated circuit switch with the function equivalent to the single-pole double-throw switch, so that the rotating motor or the retracting motor can only be supplied with power, the rotating motor and the retracting motor can not be started simultaneously, namely, when the rotating motor is started, the retracting motor can not be started, and when the retracting motor is started, the rotating motor can not be started. In addition, a single-pole triple-throw switch can be adopted, wherein the single-pole triple-throw switch comprises a gear which can disconnect the retraction motor and the power supply of the rotating motor. As for the use of semiconductor devices, integrated circuit switches or electronic switches, it belongs to the prior art.
Secondly, the rotating motor and the retracting motor must be started strictly according to the following starting sequence:
And 2, reversely starting the retracting motor for releasing the retracted blades. After the retraction motor is started reversely, the power supply of the retraction motor is disconnected after part or all of the horizontal blades are released.
And 3, performing the step 1 or the step 4.
And 4, starting the rotating motor in the positive direction, and releasing the inclination of the blade. And the rotating motor keeps being started in the positive direction, and the power supply of the rotating motor is disconnected after the blades are continuously inclined to be less than or equal to 90 degrees.
And 5, starting the rotating motor reversely to return the inclined blade.
And 6, performing the step 1 or the step 4.
The above steps must be performed in sequence and cannot be skipped. The single-pole double-throw switch or the semiconductor device or the integrated circuit switch with the function equivalent to the single-pole double-throw switch has to firstly connect the power supply with the retraction motor to ensure that the retraction motor is started in the forward direction and started in the reverse direction, and after the rotation motor is connected, firstly the rotation motor is started in the forward direction and then started in the reverse direction. And then, and so on. For example, after step 1, step 2 cannot be skipped and step 3 can be performed because after the blades are folded, there is no need to rotate the blades, and once the bearing is rotated, the notches are no longer horizontal and the blades cannot be released. For another example, after step 3, step 4 cannot be skipped and step 5 cannot be performed because the slats of the blind are damaged once the retraction motor is started under the condition that the slats are not in the horizontal state if the slats cannot be returned after rotating. Therefore, after the rotating motor is started in the forward direction, the rotating motor must be started in the reverse direction again, so that the retracting motor can be started after the blades return to the horizontal position.
In the execution process of any step, the power is turned on again after the power is cut off, and the step executed when the power is cut off is restarted. That is, the blades can be completely folded, or the power supply of the folding and unfolding motor can be turned off after partial blades are folded, and at the moment, only the lower part of the blades of the shutter are folded. If the folding is continued, the folding and unfolding motor can be started to be started in the positive direction, and the ideal folding degree is achieved all the time. In the same way, the blades can be rotated to an inclination angle of 90 degrees, or the power supply of the motor can be turned off after the blades are inclined to any angle smaller than 90 degrees, and when the blades are further inclined to an ideal angle, the rotating motor is started in the positive direction.
Or the steps can be divided into two cases: steps 1, 2, 3 represent a first cyclical operating condition, steps 4, 5, 6 represent a second cyclical operating condition, which must be satisfied if the first cyclical operating condition has been performed at least once.
For example, the first cycle operating condition is: after step 1 is performed, step 2 is performed, and then step 1 is performed. Or step 2 is performed and then step 1 is performed. In this case, only the blades are retracted and not rotated.
The second cycle operating condition is: after step 2 in the first cycle, step 4 is executed, step 5 is executed again, and step 4 is executed without executing step 1, in which case only the rotation and return of the blades are performed, and the blades are not stored.
In a special case, such as when a power failure occurs or a fault requiring power failure occurs, when power is restored, the cyclic operating condition at the time of the fault must first be switched on. That is, the failure occurs in the first cycle operation, and when power is re-applied, the retraction motor must first be turned on. The fault occurs in the second cycle operating condition, and when re-energized, the rotating electrical machine must first be turned on.
For example, in the first cycle working condition, when the retraction motor is started reversely, the retraction motor is restarted after the power failure occurs, that is, the retraction motor is stopped when the blades are released. If the reverse starting cannot be carried out, the retraction motor can be started in the forward direction to enable the blades to be folded and then released, in a word, the first cycle working condition still needs to be recovered, and the rotating motor can not be started in the forward direction firstly, namely the second cycle working condition can not be recovered.
Similarly, in the second cycle, when the rotating electrical machine is started in reverse, a fault occurs and the electrical power is cut off, i.e. the blades are stopped while being returned, then after the electrical power is restored, the rotating electrical machine is first restarted in reverse. If the reverse start is still not possible, the rotating machine can also be started in the forward direction to rotate the blades and then returned to the second cycle, in any case, it must still be possible to return to the second cycle, never starting the rotating machine in the forward direction first, i.e. not to return to the first cycle.
Or after power failure occurs in the process of executing any one of the steps, the power is re-supplied, and the steps executed during the power failure are re-executed. That is, if the power is cut off when the slats are being folded, at this time, only part of the slats of the blind are already folded, after the power is turned on, the retraction motor is started at first to start in the forward direction, and the slats are continuously folded, so that the ideal folding degree is achieved. Similarly, if the power is cut off when the blades are being released, at the moment, only part of the blades of the louver are released, after the power is switched on, the retraction motor is started at first to be started reversely, and the blades are put down continuously to achieve the ideal release degree.
If the power is cut off when the blades are rotating, at the moment, if the blades do not rotate at the ideal inclination angle, after the power is turned on, the rotating motor is started to rotate in the forward direction, and the blades are continuously inclined to reach the ideal inclination angle. Similarly, if the blade is being reset and is de-energized, then if the blade has not reached the desired angle, then after energizing, the rotating electrical machine is first started to reverse direction to bring the tilted blade to the desired tilt angle or horizontal angle.
In order to ensure that the normal sequence is executed on duty and can be correctly recovered to a normal state under the fault condition, a controller can be designed, a programmable controller is adopted to realize or a singlechip is adopted to realize sequence control, the sequence control comprises the functions of a single-pole double-throw switch and the sequence of all the steps, and the controller can be controlled by a remote controller.
The controller can also comprise a sequence setting device which is realized by a programmable controller or a singlechip and is used for setting that the rotating motor can be started only after the retracting motor is started reversely and rotates to a preset angle; after the rotating motor is set to be started reversely and rotates to a preset angle, the retracting motor can be started; after the retraction motor is set to be started in the forward direction, the retraction motor can be started in the reverse direction; after the rotating motor is set to be started in the forward direction, the rotating motor can be started in the reverse direction.
If manual control is fully utilized, the operations should also be performed in the order described above. If only the rotation of the blades is controlled by the motor and the retraction of the blades is controlled manually, the operation should be performed in the above sequence.
If the blind window only comprises a rotating motor and does not comprise a retraction motor, the control method of the blind window comprises the following steps:
step 211, the rotating motor is started in the forward direction for inclining the horizontal blade;
in step 212, the rotating electrical machine is started in reverse for returning the tilted blade.
In step 213, go to step 211.
Step 211 further includes step 221, the rotating electrical machine is started in the forward direction, and the power of the rotating electrical machine is cut off after the blades are inclined to be less than or equal to 90 degrees.
Step 211 further includes step 231, after the power is re-applied, executing step 212 or 221.
If the louver comprises not only a rotating motor but also a retracting motor, the step 211 comprises the following steps:
241, starting a retraction motor in a forward direction for furling the horizontal blades;
242, reversely starting a retraction motor for releasing the furled blades;
in step 243, step 241 or step 211 is performed.
Step 241 includes step 251, after the retraction motor is started in the forward direction, the power supply of the retraction motor is cut off after a part or all of the horizontal blades are folded.
The step 241 includes a step 261 of executing the step 212 or the step 251 after the power is turned on again.
And in the execution process of any step, after power failure occurs, the power is re-supplied, and the step executed in the power failure is re-executed.
