[0020] A first motor 8 is provided on one side of the upper frame 1, and the first motor 8 is connected to the reel 7 through a coupling. The first motor 8 works to drive the reel 7 to rotate, so that the first pull rope 602 can be retracted and released. When the first pull rope 602 is reeled in, the first pull rope 602 pulls one side of the blade 601 upward, and the other side of the blade 601 is fixed by the second pull rope 603. Therefore, the first pull rope 602 will pull one side of the blade 601 to rotate upward, thereby closing the blade 601 and putting the venetian blind 6 in a closed state; when the first pull rope 602 is released, the blade 601 will rotate downward, thereby unfolding the blade and putting the venetian blind 6 in an open state.

[0021] A slide 9 is connected to one side of the upper frame 1 via a position adjustment mechanism. A second motor 10 is mounted on the slide 9. The second motor 10 is connected to a transmission shaft via a coupling. A first gear 11 is connected to the transmission shaft. A second gear 12 is connected to one end of the reel 7. The slide 9 can be driven toward the first motor 8 by the position adjustment mechanism so that the first gear 11 meshes with the second gear 12. The position adjustment mechanism includes two bearing plates 13 connected to one side of the inner side of the upper frame, a screw rod 14 rotatably connected to the two bearing plates, and a guide rod 15 connected to the two bearing plates. The lower end of the screw rod 14 extends into the right side frame 2 and is connected to a first bevel gear 16 at the extended end. A rotating shaft 17 is rotatably connected to the upper part of the right side frame 2.

When the first motor 8 is damaged, the handle 18 is turned to drive the rotating shaft 17 to rotate. The rotating shaft 17 drives the screw 14 to rotate through the cooperation of the second bevel gear 21 and the first bevel gear 16, thereby driving the slide plate 9 to move toward the first motor 8 until the first gear 11 is engaged with the second gear 12. At this time, the second motor 10 is controlled to work, which can also drive the reel 7 to rotate and open the blinds 6.

[0022] A photovoltaic panel 19 is connected to the outside of the right frame 2. A battery and control board are located inside the right frame 2. The first motor 8, the second motor 10, and the battery are all electrically connected to the control board. The photovoltaic panel 19 is electrically connected to the battery.
