The configuration of the present invention will be described in detail as follows.

3 and 4, the automatic opening and closing apparatus 100 is installed in any one pair of sliding doors 21 which are opened and closed among at least one pair of the sliding doors 20 to automatically open and close the door 21 do. The automatic opening and closing apparatus 100 may be installed in an upper portion or a lower portion, or both an upper portion and a lower portion of an opening portion 21a in which a pair of window shades 20 are separated from each other. In the present invention, an example in which the automatic opening and closing apparatus 100 is installed at the upper portion and the lower portion of the opening portion 21a will be shown and described.

In this case, the automatic opening and closing apparatus 100 may be exposed to the outside when the case 21b coupled to the opening 21a is removed.

5, the automatic opening and closing apparatus 100 includes a driving motor 110 installed in an opening 21a of a sliding window 21 to be opened and closed, and a driving motor 110 rotated by receiving power from the driving motor 110 And a driving roller 120 provided on one surface 23a of the adjacent fixed window 23 to face the outer surface of the window 21 to open and close the window 21. [

In addition, the automatic opening and closing apparatus 100 may further include an electromagnetic clutch 130 for switching the window 21 to be opened or closed manually or automatically. The electromagnetic clutch 130 is installed on the shaft 111 connecting the drive motor 110 and the drive roller 120 to selectively cut off the power transmitted to the drive roller 120, At any time, the window 21 can be manually opened and opened.

The first gear 113 is integrally coupled to the rotating shaft of the driving motor 110 and the first gear 113 is connected to the second gear 115, And drives the driving roller 120 in such a manner that the shaft 111 is rotated. At this time, the second gear 115 is idly coupled to the shaft 111. On the same axis line of the shaft 111, the electromagnetic clutch 130 is coupled to the second gear 115 in parallel. The electromagnetic clutch 130 is integrally coupled with the shaft 111 and is rotated, and an electromagnet (not shown) is provided therein.

Therefore, when a current is applied to the electromagnet of the electromagnetic clutch 130, the second gear 115 provided adjacent to the electromagnet is rotated integrally with the electromagnetic clutch 130 so that the power of the driving motor 110 To the driving roller 120 so that the window 21 can be automatically opened and closed.

On the other hand, if the current flowing through the electromagnet is blocked, the electromagnetic clutch 130 and the second gear 115 are separated from each other and the power of the driving motor 110 transmitted to the driving roller 120 is cut off. Therefore, when the power failure or the automatic opening and closing apparatus 100 fails, the window 21 can be opened and closed smoothly.

In this case, the first gear 113 and the second gear 115 may be configured as spur gears, but it is preferable to use a helical gear so as to reduce generated noise.

Referring to FIG. 6, the driving roller 120 may be formed of rubber or urethane so as to improve adhesion with the window 23 where the outer circumferential surface of the driving roller 120 abuts.

In addition, a plurality of uneven grooves 121 may be formed on the outer circumferential surface of the driving roller 120 so as to provide frictional force upon contact with the one surface 23a of the window 23.

7, the automatic opening and closing apparatus 100 may further include a position adjusting device 150 for pressing the outer peripheral surface of the driving roller 120 against one surface 23a of the window 23. That is, the outer circumferential surface of the driving roller 120 may not be in close contact with the one side surface 23a (see FIG. 6) due to an assembly tolerance error between the components during installation of the automatic opening and closing apparatus 100. In other words, the power transmission may be unreliable even if the interval between the one side 23a of the window and the outer circumferential surface of the driving roller 120 is as small as 1 to 2 mm.

Therefore, it is necessary to provide a separate position adjusting device 150 so as to easily adjust the distance between the driving roller 120 and the window 23, thereby providing a frictional force necessary for automatic opening and closing of the window 21.

The magic glass used in the light control unit 300 is a laminated glass structure in which an ITO film and a liquid crystal are sandwiched between two sheets of glass. The light adjusting unit 300 can change a molecular arrangement between films by applying a voltage to a magic glass, instantly change from an opaque state to a transparent state, and change the transparency according to a change in voltage.

Specifically, in the state where no voltage is applied, liquid crystals appearing as rod-like molecules align along the inner wall of the capsule. In this state, the light incident on the magic glass is refracted from the capsule surface or inside due to the difference in the refractive index between the polymer and the liquid crystal and the birefringence of the liquid crystal. As a result, the light does not go straight and it appears to be opaque due to spawning.

On the contrary, when a voltage is applied, the liquid crystal molecules are arranged in a direction perpendicular to the electrodes because of the property of being parallel to the direction of applying the voltage. When the liquid crystal having the refractive index coincides with the refractive index of the polymer in this arrangement state is the same as the liquid crystal having no interface of the capsule, the light is straightened without scattering. Therefore, the magic glass looks transparent.
