Description

Technical Field

[0001] The utility model relates to the technical field of blinds, in particular to a photovoltaic power generation blind. Background Art

[0002] Venetian blinds can achieve the required indoor lighting requirements and protect privacy by adjusting the deflection angle of the curtain blades; they can achieve an excellent cleaning-free effect by preventing dust from contaminating the blind blades; and they can improve the grade of buildings by providing ideal embellishment.

[0003] Currently, there are both manual and electric Venetian blinds. Electric Venetian blinds operate by using a motor to control the rotation of a reel, which in turn rotates the blades by pulling a cord. However, the motor requires either an external power source or batteries. External power requires wiring and plugging the window, while batteries require constant battery replacement, both of which are inconvenient. Furthermore, when rewinding the cord, current Venetian blinds tend to wind up in the same spot on the reel, resulting in uneven cord movement and an increased reel diameter. This can easily cause the cord to rub against the window frame, damaging it and causing it to become tangled, making it difficult to release the next time. Utility Model Content

The reel 8 is located between the first and second partitions 5, 6, and the motor 9 is connected to the reel 7 through a coupling. The operation of the motor 9 can drive the reel 7 to rotate, thereby driving the reel 8 to rotate to release or reel in the pull rope, thereby closing or opening the blind 4.

[0022] The top frame 1 is also provided with two guiding mechanisms, which include a screw rod 10 rotatably connected to the first and second partitions, a guide rod 11 connected to the first and second partitions, a slider 12 threadedly connected to the screw rod, side plates 13 connected to both sides of the slider, a rotating shaft 14 rotatably connected to the two side plates, and a guide wheel 15 fixedly connected to the rotating shaft.
