It is an object of the present invention to provide a screen which is formed to correspond to a window and adjusts the amount of transmitted sunlight while being raised and lowered. A solar cell module mounted on the outer surface of the closing member, and the solar cell module is mounted on the outer surface of the solar cell module, And the solar blind is converted into electric energy and supplied to the power source of the driving unit.

The closing member is hollow inside and has an upper portion formed with a narrowing slit portion which is fitted to the lower end of the screen and is narrowed.

The closure member may be circular, square, or triangular in cross section, and the second solar module may be detachably coupled to the outer surface of the closure member by a detachable unit.

The sub solar module is also formed in the housing, and the solar module and the sub solar module of the closing member are connected by a power cable, and the power cable is closely attached to the back surface of the screen.

According to the present invention, since the power of the motor can be supplied by power generation using solar light, complicated power wiring work can be omitted, the construction cost can be significantly reduced, and the size of the blind and the driving force The number of solar modules to be mounted can be appropriately adjusted by adjusting the voltage and the current so that the weight can be reduced while an appropriate voltage can be provided and the performance can be improved.

FIG. 4 is a cross-sectional view of various embodiments showing an example of coupling of a 'lower closure member and a second solar module' in an electric blind using photovoltaic power generation. Detachment means'.

1 to 4, an electric blind A using solar power generation according to an embodiment of the present invention includes a screen 100 (see FIG. 1) that is formed to correspond to a window and adjusts the amount of transmitted sunlight while being raised and lowered ); A housing 200 mounted on an upper end of the window frame and having a driving part 250 for raising and lowering the screen 100; A closure member 3 coupled to the lower end of the screen 100 and a solar module 5 mounted on the outer surface of the closure member 3.

Accordingly, the solar module 5 converts solar light into electric energy and supplies the electric power to the driving unit 250.

The screen 100 is made of a fabric or a synthetic resin material having a non-transmitting or semi-transmitting property. The screen 100 is raised and lowered to control the amount of sunlight coming in through the window. Further, the window 100 is shielded to provide privacy and comfort .

The screen 100 may be woven by incorporating metal yarn and may be woven by incorporating wires, conductive polymer pastes or metal pastes at the time of fabric weaving, or the wires may be fixed to the fabric by post- . When a carbon heating element fabric combined with a carbon fiber yarn is used, heat can be dissipated to help indoor heating. The fabric of the present invention can also be applied to roll screens, combination blinds, honeycomb blinds, venetian blinds, and the like.

The driving unit is constituted by a shaft around which the screen 100 is wound, a motor for rotating the shaft, a reduction gear, and the like, which exerts the power to wind the screen 100 and wind it up or down.

Accordingly, the screen 100 is wound or unwound while the screen 100 is lifted or lowered in conjunction with forward and reverse rotation of the motor.

The construction and operation of such electric blinds are well known and those skilled in the art can easily understand the structure of such electric blinds, so that a detailed description thereof will be omitted.

It is preferable that the closing member 3 has a hollow shape and a pipe-like shape in which a narrowing slit portion 30 is formed at the upper portion of the lower portion of the screen 100 to be narrowed.

The narrowing slit portion 30 is formed so that elastic pieces 31 to be pressed on both surfaces of the closing member 3 are spaced apart from each other with a predetermined interval (the same interval as the thickness of the closing member is appropriate) A space is formed so that the lower end of the closing member 3 is inserted.

The closure member 3 may be circular, square, triangular or rhombic in cross section.

The solar module 5 is formed on the outer surface of the closing member 3 and the solar module 5 may be formed on only one side of the closing member 3 or on both sides of the closing member 3, And the closure member 3 are adhered and fixed together.

Here, the solar module 5 may be a coupling using a detachable structure so as to be detachable from the closure member 3.

4, a fitting protrusion 51 is formed on one surface of the solar module 5, and a fitting hole 35 is formed on one surface of the covering member 3 so as to correspond to the fitting protrusion 51. As shown in FIG. 4, .

Alternatively, another embodiment of the detachable structure may be a velcro fastener (not shown) in which the solar module 5 and the closure member 3 are formed and attached to each other.

It is to be understood that the present invention is not limited thereto and that various types of detachable structures can be included in the technical idea of the present invention.

On the other hand, the sub solar module 8 may be formed in the housing 200 mounted on the top of the window frame.

In addition, the solar module 5 and the sub solar module 8 of the closing member 3 are connected to each other through the power cable 400 so as to be electrically connected.

The power cable 400 is formed to be in close contact with the back surface of the screen 100 so that the winding operation can be smoothly performed.

Hereinafter, the operation of the present invention will be described.

The housing 200 is mounted on the upper portion of the window frame and the driving unit 250 is mounted in the housing 200 and the screen 100 is connected to the driving unit 250 so as to correspond to the window.

A closure member 3 is coupled to the lower end of the screen 100 and a solar module 5 is formed outside the closure member 3.

A power cable 400 for connecting the solar module 5 and the motor of the driving unit 250 is disposed via the back surface of the screen 100. [

Therefore, it can be used as a power source for driving the driving unit 250 by using the electric energy generated from the solar module 5.

When the position of the sun is changed, after the closure member 3 with the solar module 5 attached thereto is detached from the screen 100, the solar module 5 is relocated toward the side receiving a lot of sunlight, Can be stably maintained.

The sub solar module 8 is also formed in the housing 200 so that the driving unit 250 operates by receiving the electric energy generated from the solar module 5 and the sub solar module 8.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
