With the continuous improvement of the scientific and technical level and the continuous development of the intelligent home technology, more and more home equipment can be intelligently controlled through technical improvement. For example, the shutter curtain can also be intelligently controlled by arranging a curtain motor and a control device.

In order to reduce the volume and save the cost, the intelligent blind is usually provided with only one curtain motor. And a single curtain motor can only control the stroke position of the shutter or the blade inclination angle of the shutter at the same time. That is, when the curtain motor controls the stroke of the blind, the inclination angle of the blades of the blind cannot be maintained at the same time.

Therefore, in order to prevent the instability of the blade inclination angle of the blind during the movement of the stroke position of the blind, the blades of the blind are often adjusted to be in a closed state before the position of the blind is moved, and then the stroke of the blind is adjusted, so that the blade inclination angle before the shutter cannot be restored after the movement of the stroke position of the blind, and the use experience of a user is affected.

The following description is provided to illustrate an application environment of the control method of the window blind.

Referring to fig. 1 and 2, fig. 1 and 2 are schematic structural views illustrating a venetian blind according to an embodiment of the present invention. As shown in fig. 1 and 2, the window blind 100 may include a blade 110 and a driving motor 120.

In some embodiments, the window blind 100 may further include a housing 130. The driving motor 120 may be disposed in a receiving cavity formed by the housing 130.

Therein, the window blind 100 may include a plurality of vanes 110. The plurality of blades 110 are arranged in parallel. Preferably, the plurality of blades 110 are arranged in parallel. In some embodiments, the plurality of blades 110 are connected by a connecting line. The plurality of blades 110 may be connected to the driving motor 120 through a connection line. The driving motor 120 can drive the plurality of blades 110 to adjust the stroke position. In some embodiments, as shown in FIG. 1, a plurality of blades 110 are arranged in a first direction. The driving motor 120 may move the plurality of blades 110 in the second direction to change the stroke positions of the plurality of blades 110. In some embodiments, as shown in fig. 3, fig. 3 illustrates a schematic structural view of a window blind according to another embodiment of the present invention, wherein a plurality of blades 210 are arranged along a second direction. The driving motor is disposed in the accommodating cavity of the housing 230.

Fig. 4 shows a side view of one of the blades 110 of fig. 1, wherein the blade 110 comprises an opposite first face 111 and an opposite second face 112. As shown in fig. 4, the driving motor 120 may drive the blades 110 to rotate in a forward rotation direction a in fig. 4 to change the blade pitch angle of the blades, or in a reverse rotation direction B in fig. 4 to change the blade pitch angle of the blades.

After the blades in fig. 4 are rotated 180 ° in the normal rotation direction a or in the reverse rotation direction B, the blade pitch angles of the blades are adjusted to a second operating angle, as shown in fig. 5.

In some embodiments, the blades in fig. 4 rotate in the forward rotation direction a, the amount of light transmission of the window blind 100 gradually increases, and the amount of light transmission of the window blind is the greatest when the blade angle is rotated by 90 ° in the forward rotation direction a from the first operation angle, as shown in fig. 6. In some embodiments, the blades in fig. 4 rotate in the reverse direction B, and the amount of light transmitted by the window blind 100 gradually increases, and the amount of light transmitted by the window blind is the greatest when the blade angle is rotated 90 ° in the reverse direction B from the first operating angle, as shown in fig. 7.

In some embodiments, the window blind is further provided with a communication module. The communication module can be connected with the mobile terminal through a network so as to carry out data transmission with the mobile terminal. In some embodiments, the mobile terminal may be, for example, a mobile phone, a computer, an intelligent switch control panel, and the like, which is not limited in this application. In some embodiments, the network may be, for example, a ZigBee (violet), WIFI (Wireless Fidelity), bluetooth, or the like network.

In some embodiments, the window blind is further provided with a control module. The control module is connected with the communication module. The communication module can transmit the received instruction to the control module, and the control module can control the driving motor to adjust the stroke position of the blind curtain and the blade inclination angle of the blades according to the instruction.

Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 8, an embodiment of the present application provides a method for controlling a window blind, which is applicable to a window blind, and the present embodiment describes a flow of steps of a window blind side, and the method may include steps S110 to S150.

And step S110, receiving a stroke control command for the window blind.

In an embodiment of the present application, a blind receives a stroke control command for the blind.

In some embodiments, the user may send the stroke control instruction for the blind via the interactive interface of the mobile terminal. For example, the interactive interface presents real-time travel positions of the window blinds. The user can directly adjust the blind window curtain on the interactive interface, such as adjusting the stroke position of the blind window curtain. And if the stroke position and the blade inclination angle of the blind curtain are adjusted, the mobile terminal correspondingly generates a stroke control command for the blind curtain. And the mobile terminal sends the stroke control command to the blind. Therefore, the blind window receives the stroke control instruction through the communication module.

And step S120, determining the initial angle of the blades of the current venetian blind.

The driving motor of the shutter curtain can only control the stroke or the inclination angle of the blades at the same time. When the driving motor of the blind window curtain controls the stroke of the blades, the inclination angles of the blades of the blind window curtain cannot be controlled simultaneously.

In order to allow the blind to restore the blade inclination angle before adjustment after the stroke position adjustment. The embodiment of the application firstly determines the angle corresponding to the inclination angle of the blades of the blind before stroke adjustment, namely the initial angle of the blades. After the initial angle of the blade is determined, the angle information of the initial angle of the blade can be recorded, so that the angle information of the initial angle of the blade can be retrieved later to restore the blade inclination angle to the initial angle of the blade.

Step S130, adjusting the inclination angle of the blades of the current shutter curtain to a blade operation angle, wherein the blade operation angle is an angle at which the inclination angle of the blades of the shutter curtain is kept unchanged in the operation process.

In an embodiment of the present application, the window blind adjusts the blade inclination angle of the current window blind to the blade operation angle. Illustratively, the blade angle of the window blind in fig. 1 is used as the initial blade angle, and the blade angle of the window blind in fig. 1 is adjusted to the blade running angle, as shown in fig. 9.

In the embodiment of the application, the blades of the window blind have the least light transmission when the blade inclination angle is the blade running angle. The clearance between the adjacent blades is minimum, and the angle of the blades is kept relatively stable and unchanged. In order to ensure that the angle of the slats remains relatively stable during the adjustment of the stroke position of the window blind, and the window blind can move stably, in the embodiment of the present application, before the adjustment of the stroke position of the window blind, the tilt angle of the slats of the current window blind is adjusted to the slat operating angle.

In the embodiment of the present application, the vane angle of the current blind is adjusted to the vane operating angle by rotating the vane of the blind to a tilt angle fixing position, i.e., a position where the amount of light transmission of the blind is minimized.

And step S140, controlling the stroke position of the blind according to the stroke control command.

In an embodiment of the present application, the blind controls the stroke position of the blind according to the stroke control command. Illustratively, on the basis of fig. 9, the blind controls the stroke position of the blind in accordance with the stroke control command, as shown in fig. 10.

In some embodiments, if the stroke control command includes a target stroke position, the blind is controlled to operate to the target stroke position. In some embodiments, the fully deployed travel position of the blind is 0cm and the fully retracted travel position of the blind is 100 cm. For example, the stroke control command includes a target stroke position of 50cm, and if the current stroke position of the blind is 20cm, the blind moves the blind in the first direction by 30cm from the current stroke position according to the stroke control command, so that the blind is controlled to move to the target stroke position according to the stroke control command.

In some embodiments, if the stroke control command does not include the target stroke position, the blind is controlled to operate to a preset stroke position. For example, the user merely issues a stroke control command for raising a curtain via the mobile terminal, but the user does not specify a specific height adjustment. At this time, the shutter curtain can be heightened to a preset height so as to control the shutter curtain to move to a preset stroke position. The preset height may be, for example, 5cm, 8cm, and the like, and may be set according to an actual use requirement of a user, which is not limited in this application.

And S150, restoring the inclination angle of the blades of the blind from the blade running angle to the initial angle of the blades.

In an embodiment of the present application, the blind restores the blade inclination angle of the blind from the blade running angle to the blade initial angle. Illustratively, on the basis of FIG. 10, the blind restores the blade pitch angle from the blade running angle to the blade initial angle, as shown in FIG. 11.

In some embodiments, after step S140, the blind rotates the blades to restore the blade inclination angle from the blade running angle to the blade initial angle, thereby restoring the blade inclination angle before the stroke control. Namely the light transmission amount of the blind curtain before the stroke control is recovered. That is, after the stroke position of the blind is adjusted, the inclination angle of the blades of the blind is not changed, so that the effect of adjusting the stroke position of the blind in a non-inductive manner is achieved.

The shutter curtain provided by the embodiment of the application determines the initial blade angle of the current shutter curtain by receiving the stroke control instruction for the shutter curtain, adjusts the blade inclination angle of the current shutter curtain to the blade operating angle, the blade operating angle is the angle at which the blade inclination angle of the shutter curtain is kept unchanged in the operating process, the stroke position of the shutter curtain is controlled according to the stroke control instruction, and the blade inclination angle of the shutter curtain is restored to the initial blade angle from the blade operating angle, so that the initial blade angle of the shutter curtain is obtained before the shutter curtain moves in the stroke position, the initial blade inclination angle of the shutter curtain is restored to the initial blade angle in time after the shutter curtain moves in the stroke position, the influence of the position movement on the blade inclination angle is reduced, and the use experience of a user is improved.

Referring to fig. 12, another embodiment of the present application provides a method for controlling a window blind, which can be applied to a window blind, and the present embodiment describes a flow of steps of a window blind side, and the method can include steps S210 to S260.

And step S210, receiving a stroke control command for the window blind.

And S220, determining the initial angle of the blades of the current venetian blind.

For the detailed description of steps S210 to S220, refer to steps S110 to S120, which are not described herein again.

Step S230, if the rotation angle required for adjusting the blade inclination angle of the window blind from the blade initial angle to the first operation angle is smaller than the rotation angle required for adjusting the blade inclination angle of the window blind from the blade initial angle to the second operation angle, adjusting the current blade inclination angle of the window blind to the first operation angle.

In an embodiment of the present application, the blade operating angles include a first operating angle and a second operating angle, the first operating angle and the second operating angle differing by 180 degrees. That is, the light transmission amount of the blind is minimum when the inclination angle of the blades of the blind is the first operation angle or the second operation angle, and the angle of the blind is maintained unchanged during the operation.

That is, in order to maintain the slats of the window blind to remain unchanged during the stroke position adjustment, the slat inclination angle of the slats may be adjusted to the first operating angle, or the slat inclination angle of the slats may be adjusted to the second operating angle.

Further, if the angle of rotation required for adjusting the blade inclination angle of the window blind from the blade initial angle to the first operating angle is smaller than the angle of rotation required for adjusting the blade inclination angle of the window blind from the blade initial angle to the second operating angle, the current blade inclination angle of the window blind is adjusted to the first operating angle, so that the rotation process of the blades of the window blind is further optimized, the blade inclination angle of the window blind is adjusted to the blade operating angle (here, the first operating angle) at the minimum angle, and the adjustment efficiency is improved.

Step S240, if the rotation angle required for adjusting the blade inclination angle of the window blind from the blade initial angle to the first operation angle is greater than the rotation angle required for adjusting the blade inclination angle of the window blind from the blade initial angle to the second operation angle, adjusting the current blade inclination angle of the window blind to the second operation angle.

Similarly, if the angle of rotation required by the blade inclination angle of the window blind to be adjusted from the blade initial angle to the first operating angle is greater than the angle of rotation required by the blade inclination angle of the window blind to be adjusted from the blade initial angle to the second operating angle, the blade inclination angle of the current window blind is adjusted to the second operating angle, so that the rotation process of the blades of the window blind is further optimized, the blade inclination angle of the window blind is adjusted to the blade operating angle (here, the second operating angle) at the minimum angle, and the adjustment efficiency is improved.

And step S250, controlling the stroke position of the blind according to the stroke control command.

And S260, restoring the inclination angle of the blades of the blind from the blade running angle to the initial angle of the blades.

For the detailed description of steps S250 to S260, refer to steps S140 to S150, which are not described herein again.

Another embodiment of the present application relates to a blind control method. Another embodiment of the present application is improved on the basis of the above embodiment, and the main improvements are as follows: the rotation process of the shutter blades rotating to the blade operation angle is further optimized, the shutter is adjusted to the blade operation angle at the minimum angle, and the adjustment efficiency is improved.

Referring to fig. 13, another embodiment of the present application provides a method for controlling a window blind, which can be applied to a window blind, and the present embodiment describes a flow of steps of a window blind side, and the method can include steps S310 to S360.

And step S310, receiving a stroke control command for the window blind.

And step S320, determining the initial angle of the blades of the current venetian blind.

And S330, adjusting the inclination angle of the blades of the current shutter curtain to a blade operation angle, wherein the blade operation angle is an angle at which the inclination angle of the blades of the shutter curtain is kept unchanged in the operation process.

And step S340, controlling the stroke position of the blind according to the stroke control command.

For the detailed description of steps S310 to S340, refer to steps S110 to S140, which are not described herein again.

And step S350, if the stroke control command does not comprise the target angle of the blades, restoring the inclination angle of the blades of the blind from the operation angle of the blades to the initial angle of the blades.

In the embodiment of the application, if the stroke control command does not include the target angle of the blade, the user only controls the stroke position of the blind, and does not control the blade inclination angle of the blind. The inclination angle of the slats of the window blind is restored from the slat running angle to the slat initial angle.

In some embodiments, the blade inclination angle of the window blind may be rotated in a first direction or a second direction by the blade running angle so that the blade inclination angle is restored to the blade initial angle from the blade running angle. Further, in order to optimize the rotation process of the window blind, the inclination angle of the vanes is restored from the vane running angle to the vane initial angle at the minimum angle, and the initial rotation direction may be determined according to the vane initial angle. The initial rotation direction is a direction in which the rotation angle required for rotating the inclination angle of the slats of the window blind from the running angle of the slats to the initial angle of the slats is the smallest. Further, the blind is rotated in the initial rotation direction to restore the inclination angle of the slats of the blind from the running angle to the original angle of the slats,

and S360, if the lifting control command comprises a blade target angle, adjusting the blade inclination angle of the blind to the blade target angle from the blade operation angle.

In some embodiments, if the lift control command includes a target angle of the slats, the user may need to adjust the tilt angle of the slats in addition to the position of the travel of the window covering. At this time, the inclination angle of the blades of the blind is adjusted from the initial angle of the blades to the target angle of the blades.

Further, in order to make the user feel the adjustment process of the blade pitch angle, please refer to fig. 14, step S360 of the embodiment of the present application may further include steps S361 to S362.

And S361, restoring the inclination angle of the blades of the shutter curtain from the blade running angle to the initial angle of the blades.

In the embodiment of the present application, the adjustment of the blade inclination angle of the blind from the blade operating angle to the target blade angle can be divided into two processes. The first process is to restore the blade inclination angle of the shutter from the blade running angle to the blade initial angle.

In some embodiments, the window blind may first rotate the slats at a first predetermined rotational speed to adjust the window blind to the initial slat angle.

And S362, adjusting the inclination angle of the blades of the blind from the initial angle of the blades to the target angle of the blades.

In the embodiment of the present application, the second process is to continue to adjust the tilt angle of the slats of the window blind from the initial slat angle to the target slat angle. Illustratively, on the basis of FIG. 10, the window blind continues to adjust the blade pitch angle of the window blind from the initial blade angle to the target blade angle, as shown in FIG. 15.

In order to distinguish the two adjustment processes, the user is made to experience two different adjustment processes. In some embodiments, the rotation of the slats may be continued after a preset time for the slat inclination angle of the window blind to return from the slat operating angle to the slat initial angle, so that the slat inclination angle of the window blind is adjusted from the slat initial angle to the slat target angle.

In other embodiments, the window blind may rotate the slats at a second predetermined rotational speed such that the slat pitch of the window blind is adjusted from the slat initial angle to the slat target angle.

In an embodiment of the present application, the first preset rotation speed may be set to be different from the second preset rotation speed, thereby distinguishing two rotation processes.

Further, the first preset rotation speed may be set to be greater than the second preset rotation speed. Thereby making the second rotation process more apparent.

In some embodiments, the blind may determine a target turning direction based on the initial angle of the slats and the target angle of the slats, the target turning direction being a direction that minimizes the turning angle required to turn the slats from the initial angle of the slats to the target angle of the slats. The blind rotates the slats in a target rotational direction such that the slats are adjusted from the initial tilt angle to a target tilt angle. Therefore, the rotation process of the blind is optimized, so that the blind rotates from the initial angle of the blades to the target angle of the blades at the minimum rotation angle, the efficiency is improved, and the energy consumption is reduced.
