It is to be understood that the described embodiments are merely a few embodiments of the utility model, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 4, an embodiment of the present invention provides an intelligent blind, including: at least two window blades 6, a window frame 7, a drive device, a control switch 14, a first electromagnetic device 501 and a second electromagnetic device 502; the window blades 6 are provided with window blade rotating shafts 8, and the window blades 6 are rotatably arranged on the window frame 7 through the window blade rotating shafts 8; the driving device drives the rotating shaft 8 of the window blade to rotate; the first electromagnetic device 501 is arranged at the bottom of the window frame 7 in a rotating mode, and the second electromagnetic device 502 is arranged on the window blade 6 close to the bottom of the window frame; the control switch 14 is respectively connected with the circuits of the first electromagnetic device 501 and the second electromagnetic device 502 in a control mode; when the louver blades 6 are in the open state, the first electromagnetic device 501 and the second electromagnetic device 502 repel each other.

The driving device comprises a mounting frame 10, a driving motor 1, a rotating part 4, a transmission belt 9, a first gear 2 and a second gear 3; the mounting frame 10 is mounted on the side of the window frame 7 by screws; the upper bottom of the installation frame 10 is connected with a motor base through bolts, the driving motor 1 is installed on the motor base through bolts, the first gear 2 is coaxially sleeved at the shaft end of the driving motor 1, the second gear 3 is coaxially sleeved on the rotating shaft 8 of the window vane, the driving motor 1 drives the first gear 2 to rotate, and the first gear 2 is meshed with the second gear 3 to rotate; the rotating shaft 8 of the louver extends from the side edge of the window frame 7 where the installation frame 10 is installed, the rotating member 4 is coaxially fixed on the extending end of the rotating shaft 8 of the louver, and the extending end is the end of the rotating shaft 8 of the louver extending from the window frame 7. The transmission of conveyer belt is connected and is rotated piece 4, and the conveyer belt is used for making each louver pivot 8 synchronous rotation. The first gear 2 and the second gear 3 form a gear set, and the driving motor 1 drives the window vane rotating shaft 8 to rotate through the gear set. Therefore, the installation positions of the driving motor 1 and the second gear 3 are not unique, and as long as the driving motor 1 drives the rotating part 4 to rotate through the gear set, the rotating part 4 drives the transmission belt 9 to open or close the whole shutter.

It should be noted that, when the rotating member 4 may be a third gear, the transmission belt 9 is a soft rack; the soft rack connects the gear III at the topmost end with the gear III at the lowest end to form a tight soft gear ring, and each gear III is meshed with the soft gear ring, so that the driving motor 1 drives the gear at the lowest end, and the whole shutter is opened or closed through the movement of the soft gear ring. When the rotating member 4 can also be a chain wheel, the transmission belt 9 is a chain; each chain wheel is connected to the chain through the chain to form a fastened chain ring, and each chain wheel is connected with the chain ring, so that the driving motor 1 drives the chain wheel at the lowest end to rotate, the whole blind window is opened or closed through the chain ring, and therefore the relation between the rotating piece 4 and the driving belt 9 is that the whole blind window is opened.

The first electromagnetic device 501 and the second electromagnetic device 502 form an electromagnetic device 5; the first electromagnetic device 501 is fixedly embedded at the bottom of the window frame 6, the top of the first electromagnetic device 501 is flush with the window frame 6, and the second electromagnetic device 502 is installed on the window blade 6 closest to the window frame 6 through a screw; when the window blade 6 is opened, the control switch 14 is used to make the current directions in the first electromagnetic device 501 and the second electromagnetic device 502 opposite, so that the polarity of the top surface of the first electromagnetic device 501 is the same as the polarity of the bottom surface of the second electromagnetic device 502; during the closing of the blind, the control switch 14 is used to make the current directions in the first electromagnetic device 501 and the second electromagnetic device 502 the same, so that the polarity of the top surface of the first electromagnetic device 501 is opposite to the polarity of the bottom surface of the second electromagnetic device 502.

It should be noted that the electromagnetic device 5 is only a summary of the first electromagnetic device 501 and the second electromagnetic device 502, and is not practical for the convenience of the entire description. In the process of opening the window blade 6, by using the principle that like magnetic forces repel each other, when the top surface of the first electromagnetic device 501 is an N pole, the bottom surface of the second electromagnetic device 502 is also an N pole; when the top surface of the first electromagnetic device 501 is S-pole, the bottom surface of the second electromagnetic device 502 is S-pole, so that the electromagnetic device 5 assists the driving motor 1 to open the blind. In the closing process of the shutter, by using the principle that opposite magnetic forces attract each other, when the top surface of the first electromagnetic device 501 is an N pole, the bottom surface of the second electromagnetic device 502 is also an S pole; when the top surface of the first electromagnetic device 501 is an S-pole, the bottom surface of the second electromagnetic device 502 is also an N-pole; thus, the electromagnetic device 5 assists the driving motor 1 to close the shutter, thereby reducing the working conformity of the driving motor 1 and prolonging the service life of the driving motor 1.

It should be noted that the number and type of the electromagnetic devices 5 of each window leaf 6 are the same, so that one control switch 14 can be used to control the electromagnetic devices 5. When the types and the number of the electromagnetic devices 5 are different on each blade, a control switch 14 is required to be arranged on each electromagnetic device 5, so that the magnetic field on each window blade 6 is adjusted to be consistent through the controller 13, and the electromagnetic devices 5 help the driving motor 1 to open or close the shutter. The control switch 14 is a component for adjusting the current, and can change the magnitude of the current and the direction of the current. The electromagnetic device 5 is connected with the control switch 14, and the constant passing current on the electromagnetic device 5 is direct current; the intensity of the magnetic field of the electromagnetic device 5 can be changed by changing the magnitude of the current through the control switch 14, and the magnetic pole direction of the electromagnetic device 5 can be changed by changing the direction of the current through the control switch 14. For example, the magnitude of the control current may be a rotary switch mounted in the circuit; or a current regulator; during the rotation of the shutter, when the current passing through the electromagnetic device 5 is increased, the magnetic force applied to the louver blades 6 near the bottom of the window frame is increased, so that the shutter rotates faster and the load of the motor is reduced. For example, a double pole double throw switch may be added to the circuit to control the direction of current flow. In summary, the control switch 14 is used to control the direction and magnitude of the current in the electromagnetic device 5, thereby changing the direction and intensity of the magnetic field of the electromagnetic device 5. A schematic diagram of the double-pole double-throw switch for changing the current direction of the electromagnetic device 5 is shown in fig. 4, where S is the double-pole double-throw switch, a and b are two contacts of the double-pole double-throw switch, when the S-direction contact is closed, the double-pole double-throw switch and the contact a make up a circuit, the current directions of the first electromagnetic device 501 and the second electromagnetic device 502 are the same, and when the S-direction contact is closed, the double-pole double-throw switch and the contact b make up a circuit, the current directions of the first electromagnetic device 501 and the second electromagnetic device 502 are opposite. The double-pole double-throw switch is only one type for changing the current direction in the electromagnetic device 5, and other devices can be adopted to change the current direction and the current magnitude in the electromagnetic device 5, which are all in line with the utility model.
