[0031] A signal receiver 23 is arranged on the outside of the track box 1, and is used to receive instructions transmitted from the remote control. A drive controller 24 is fixedly installed on the top of the box cover 2, and one end of the drive controller 24 is fixedly connected to a shunt line 25. When the first infrared human body sensor 9 and the second infrared human body sensor 12 on the step curtain blades 10 or the bottom pendant 8 sense that a human body is passing, the signal will be transmitted to the drive controller 24 through the signal receiver 23. The drive controller 24 is connected to other internal components by wires through the shunt line 25, so that the electric venetian blinds in the retracted state can be lowered to unfold the step curtain blades 10, or if the step curtain blades 10 are not indirectly closed, the step curtain blades 10 are controlled to complete the angle closure.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the winding drum 6 is movably connected to the track box 1, and the center line of the transmission rod 5 coincides with the center line of the winding drum 6. The winding drum 6 rotates to drive the winding rope 7 to wind or spread, thereby completing the opening and closing and winding of the electric venetian blinds. The number of step curtain blades 10 is set to twelve, and the twelve step curtain blades 10 are evenly spaced on the winding rope 7. After the step curtain blades 10 are closed, the upper step curtain blades 10 and the lower step curtain blades 10 fit together, thereby improving the overall sealing of the electric venetian blinds, which can not only prevent indoor light exposure, but also prevent external light from entering, providing a comfortable environment for people to sleep at night.

[0033] Inside the track box 1, there is a mounting bracket 13. Inside the mounting bracket 13, there is a nail box 14 movably connected. Above the nail box 14, there is a nail cover 15 fixedly installed. Outside the nail box 14, there is a fixed rod 16. Outside the fixed rod 16, there is a first bevel gear 17. The nail box 14 and the nail cover 15 fix the end of the angle rope 20 in a way of upper and lower fitting, ensuring that the angle rope 20 drives the stepped curtain leaf 10 to complete the angle adjustment work.

Outside the wedge block 19, there is an angle rope 20 fixedly installed. The wedge block 19 assists in fixing the angle rope 20 outside each stepped curtain leaf 10. In this way, when the angle rope 20 is wound upwards, the stepped curtain leaf 10 is relatively linked to complete the angle adjustment. On the top of the box cover 2, there is a second micro motor 21. The output end of the second micro motor 21 is fixedly installed with a second bevel gear 22. Components such as the first bevel gear 17 and the second bevel gear 22 are inside the track box 1. It not only has a simple structure and low manufacturing cost, but also reduces the overall maintenance difficulty in case of failure.

[0034] Such as Figure 1 , Figure 4 and Figure 5As shown in the figure, the working principle of this utility model is as follows: First, connect to the external power supply and install the device on the window of the room. When people enter the room and come to the window, the first infrared human body sensor 9 and the second infrared human body sensor 12 on the stepped curtain leaf 10 or the bottom weight 8 will transmit the signal to the drive controller 24 through the signal receiver 23 when they sense that a human body passes by. Then, the drive controller 24 is electrically connected to other components inside through the shunt wire 25. At this time, if the electric louver is in the retracted state, the switch of the first micro motor 4 will be turned on. The first micro motor 4 drives the take-up reel 6 to rotate through the transmission rod 5, releases the take-up rope 7, and allows the stepped curtain leaf 10 to slide on the take-up rope 7. In this way, the electric louver in the retracted state is lowered and the stepped curtain leaf 10 is unfolded. Then, if the stepped curtain leaf 10 is not indirectly closed, the switch of the second micro motor 21 will be turned on. The second micro motor 21 drives the second bevel gear 22 to rotate. The second bevel gear 22 is meshed with the first bevel gear 17, so that the fixed rod 16 drives the nail box 14 to rotate. The nail box 14 and the nail cover 15 fix the end of the angle rope 20 in an up-and-down fitting manner, ensuring that the angle rope 20 is retracted upward by a certain distance to drive the stepped curtain leaf 10 to complete the angle adjustment work and control the stepped curtain leaf 10 to complete the angle closing. Subsequently, after the stepped curtain leaf 10 is closed, the upper stepped curtain leaf 10 and the lower stepped curtain leaf 10 are fitted together, improving the overall sealing of the electric louver, which can not only prevent indoor light leakage but also prevent external light from entering. In this way, the purpose of preventing indoor light leakage of the electric louver is achieved. If people do not need to close the electric louver after entering the room, they can simply use the external remote control to reverse the above operations to reopen the electric louver. Finally, after completing all the opening, closing, and angle adjustment operations of the electric louver according to the above operations, turn off the switches of the first micro motor 4 and the second micro motor 21. If it is not used for a long time, cut off the external power supply. The models of the first micro motor 4 and the second micro motor 21 are: 20BYJ46, the models of the signals of the first infrared human body sensor 9 and the second infrared human body sensor 12 are: ZP-12R, the model of the signal receiver 23 is: MWLA-005060G40, and the model of the drive controller 24 is: YPD800. In this way, the use process of the electric louver for preventing indoor light leakage is completed.

[0035] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways.
