fourth link members

610, 620, 630, and 640. One of the first link members 610 is fixed to a center of rotation of any one of the driven

rollers

522, 523, 524 and 525, and the rest of the first link member 610 is The center portion is fixed to the tip of the rotation shaft 210 extending into the second space portion 120B. The second link member 620 has a pair of pins one end of which is connected to one end of the first link member 610 that is vertically adjacent to each other, and the other end of which is pin-connected to each other. In addition, the third link member 630 is pin-connected to the other end of the first link member 610, one end of which is vertically adjacent to each other, and the other end is composed of a pair of pin connected to each other. Both ends of the fourth link member 640 are pin-connected to the other end of the second link member 620 and the other end of the third link member 630, respectively. When the first and

second link members

third link members

620 and 630 are rotated. And one of the

third link members

620 and 630 ascends or descends relative to the other, so that the slat 200 rotates about the rotation shaft 210. In the process of lifting and lowering the slat 200, the other ends of the second and

third link members

620 and 630 are pivoted about one end connected to both ends of the first link member 610, respectively. As a result, the link mechanism 600 is folded all over. In this case, since the second and

third link members

620 and 630 are substantially connected by the fourth link member 640, they rotate in the same direction.

Meanwhile, in the present embodiment, the link mechanism 600 further includes a guide protrusion 650. The guide protrusion 650 serves to guide the folding direction of the link mechanism 600. In other words, the guide protrusion 650 may have the second and

third link members

620 and 630 folded in a predetermined direction inside the second space 120B, that is, to the right in the drawing in FIG. 4. The upper part of the second and

third link members

620 and 630 rotates in the counterclockwise direction about the upper end thereof, and the lower part guides the upper part to rotate in the clockwise direction about the lower end thereof. Play a role. In the present embodiment, the guide protrusion 650 is provided at the left end of the fourth link member 640 at one end of the drawing. The guide protrusion 650 may be formed of a substantially flexible material and may extend in the longitudinal direction of the fourth link member 640 from one end of the fourth link member 640. Accordingly, when the second and

third link members

third link members

620 and 630 are guided to the right side in FIG. 4. In addition, the guide protrusion 650 is formed of a flexible material, so that the guide protrusion 650 contacts the left side in the drawing of the second space portion 120B in the tilting process of the slat 200. Even if the operation of the link mechanism 600 is interfered with it can be prevented.

The input unit 700 receives a signal for raising and lowering and rotating the slat 200. For example, the input unit 700 may be provided with a button for receiving signals for lifting, lowering and rotating the slat 200, respectively.

The detector 800 includes a height detector 810 and a rotation angle detector 820. The height detection unit 810, the height of the slat 200 is raised or lowered, the rotation angle detector 820, the rotation angle of the slat 200 to detect. For example, the height detection unit 810 and the rotation angle detection unit 820 directly detects the height or rotation angle of the lifting or lowering of the slat 200, or the lifting motor 300 or the rotating motor From the number of revolutions of the rotor of 500 may be indirectly detect the height or rotation angle of the raised or lowered slat 200.

On the other hand, the control unit 900 controls the operation of the elevating motor 300 and the rotary motor 500 to raise or lower the slat 200 according to the signal received by the input unit 700. In particular, in the present embodiment, the control unit 900, even if the input unit 700 receives a signal for raising or lowering the slat 200, the rotated angle and the elevated height of the slat 200 As the slat 200 rotates or moves up and down, the input unit 700 controls the operation of the lifting motor 300 and the rotating motor 500 to move up or down according to the input signal.

More specifically, the input unit 700 is the slat 200 in a state in which the lifting angle or lowering of the slat 200 is interfered by another slat 200 adjacent to the rotating angle of the slat 200. When receiving a signal for lifting or lowering of), the controller 900 rotates the slat 200 by a predetermined angle and then moves up or down of the rotary motor 500 and the lifting motor 300. Control the operation. For example, in the state in which the slat 200 shields the opening, the adjacent slats 200 are in contact with each other, and thus, interference between the adjacent slats 200 during the ascending and descending process of the slats 200. This may occur. In this embodiment, in this case, even if a signal for lifting or lowering the slat 200 is input to the input unit 700, the control unit 900 at least adjacent to the slat 200 is spaced apart from each other. To control the operation of the lifting motor 300 and the rotary motor 500 to the lifting and lowering after the slat 200 rotates in the direction of opening the opening.

In addition, the input unit 700 rotates the slat 200 in a state where the height of the slat 200 is lowered or lowered within the range where the rotation of the slat 200 is interfered by another adjacent slat 200. When receiving a signal for the, the control unit 900, the slat 200 is lowered by a predetermined height to control the operation of the lifting motor 300 and the rotating motor 500 to rotate. For example, in a state where all or part of the slats 200 are elevated, in the case of at least some of the slats 200, the spacing between adjacent slats 200 is less than or equal to the radius of rotation of the slats 200. By doing so, rotation of the slat 200 may be interfered by another adjacent slat 200. Therefore, in the present embodiment, even if a signal for the rotation of the slat 200 is input, the slab to the position where the rotation of the slat 200 is not interfered with by another slat 200 adjacent to the slat 200 The operation of the lifting motor 300 and the rotating motor 500 is controlled to rotate after the 200 is lowered.

Particularly, in this embodiment, since one end of the chain 400 is connected to the lowermost slat 201, the ascending and descending of the slat 200 is substantially the slat located above the lowermost slat 201. It is made in the order of 200. Therefore, in the present embodiment, the upper and lower intervals between the lower end slat 201 and the lower end slat 202 located directly above the control unit 900 exceeds the rotation radius of the lower end slat 202. After the lowermost slat 201 is lowered to the position, the operation of the lifting motor 300 and the rotating motor 500 is controlled so that the slat 200 rotates.

Hereinafter, the operation of the motorized blind according to the first embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

6 and 7 are flow charts showing the motorized blind control method according to the first embodiment of the present invention, Figures 8 and 9 is an operational state diagram showing the operation of the motorized blinds according to the first embodiment of the present invention. .

First, referring to FIG. 6, in this embodiment, the lifting or lowering of the slat 200 is performed in the order of the lifting signal input step S110, the rotation angle sensing step S120, and the motor control step S130. do. In the lifting signal input step (S110), the input unit 700 receives a signal for lifting or lowering the slat 200. In the rotation angle detection step (S120), the rotation angle detection unit 820 detects the rotation angle of the slat 200. Next, in the motor control step (S130), the control unit 900, the slat 200 is raised or lowered or lowered according to the rotation angle of the slat 200 detected in the rotation angle detection step (S120) After the slat 200 rotates by a predetermined angle, the slab 200 controls the operation of the lifting motor 300 or the lifting motor 300 and the rotating motor 500 to move up or down.
