Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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. 1-5, an intelligent electric curtain comprises a side installation rod 1, a motor 3 is fixedly connected to the right side of the top end of the side installation rod 1, a threaded rod 4 is fixedly connected to the right side of the motor 3, a first sleeve 5 is connected to the left end of the threaded rod 4 in a threaded manner, a second sleeve 6 is connected to the right end of the first sleeve 5 in a threaded manner, a U-shaped magnet 7 is fixedly connected to the lower end of the threaded rod 4 and positioned at the back of the first sleeve 5, a metal guide rail 501 is fixedly connected to the lower end of the first sleeve 5, a cross bar 2 is transversely and fixedly connected to the lower end of the U-shaped magnet 7, a curtain body 11 is fixedly connected to the lower end of the cross bar 2, a fixed wheel 9 is fixedly connected to the left end of the cross bar 2, a sliding box 8 is slidably connected to the right side of the fixed wheel 9, an alternating current magnet 802 is fixedly connected to, two slide rails 806 are fixedly connected to the left side and the right side of the inner top of the sliding box 8, the first magnet 801 and the second magnet 803 are located inside the slide rails 806, a first spring 804 is fixedly connected to the lower end of the first magnet 801, a second spring 805 is fixedly connected to the lower end of the second magnet 803, and a roller 10 is slidably connected to the right end of the sliding box 8. When the window curtain is opened, induced electromotive force is generated when the metal guide 501 at the lower end of the first sleeve 5 runs into the U-shaped magnet 7, the ac electromagnet 802 is energized, the first magnet 801 moves towards the left side and the second magnet 803 moves towards the right side under the repulsive force of the homopolar magnet, and slides in the slide rail 806 to press the first spring 804 and the second spring 805, so as to open the middle part of the curtain body 11 to the same extent, when the window curtain is closed, the motor 3 rotates in the opposite direction, when the metal guide 501 runs into the U-shaped magnet, the direction of the induced electromotive force generated at this time changes due to the change of the moving direction of the metal guide 501, the ac electromagnet 802 is energized, at this time, the ac electromagnet 802, the first magnet 801 and the second magnet 803 become magnets of different grade, and under the attraction force of the magnets of different grade, the original first magnet 801 and the second magnet 803 move towards the ac electromagnet 802, restoring it to its original state. The metal guide 501 is a smooth copper rail, which reduces power loss due to excessive resistance. The pitch value of the inner diameter of the first sleeve 5 is half of the pitch value of the inner diameter of the second sleeve 6. Since the pitch of the inner diameter of the first sleeve 5 is set to be half of the pitch of the inner diameter of the second sleeve 6, the moving speed of the second sleeve 6 during the sliding process is guaranteed to be twice of the moving speed of the first sleeve 5. The slide rail 806 is provided as an arc-shaped rail and the end extends to the outside of the slide box 8, and the width of the slide rail 806 is larger than the diameter of the first magnet 801. Ensuring that the magnet then slides within the track 806 and the curtains on either side are fully opened. The first magnet 801 and the second magnet 803 are arranged in a spherical shape and are homopolar magnets, so that sliding friction is reduced, and both ends keep synchronous motion under the action of magnetic force.

The use method (working principle) of the invention is as follows:

when the curtain is opened, the motor 3 is electrified to drive the threaded rod 4 to rotate, the first sleeve 5 and the second sleeve 6 which are positioned at the upper end of the threaded rod 4 move along with the threaded rod, and because the inner diameter pitch of the first sleeve 5 is set to be half of the inner diameter pitch of the second sleeve 6, the moving speed of the second sleeve 6 is twice of the moving speed of the first sleeve 5, when the second sleeve 6 moves to the rightmost end, the opening degree of one end, close to the wall, of the curtain body 11 and the opening degree of one end, far away from the wall are the same (figure two state), in the moving process, because the metal guide rail 501 at the lower end of the first sleeve 5 moves to the inside of the U-shaped magnet 7, induced electromotive force is generated, the alternating current electromagnet 802 is electrified, under the repulsion action of the homopolar magnet, the first magnet 801 moves towards the left side, the second magnet 803 moves towards the right side, slides, the middle part of the curtain body 11 is opened to the same degree (the state shown in figure 3), the gravity center of the curtain body 11 is always kept at the central point of the geometric position of the curtain in the whole curtain opening process, and the moment in the curtain moving process is effectively reduced; when the curtain is closed, the motor 3 rotates in the reverse direction, when the metal guide track 501 moves into the U-shaped magnet, the moving direction of the metal guide track 501 changes, the direction of the induced electromotive force generated at this time changes, the ac electromagnet 802 is energized, the ac electromagnet 802, the first magnet 801 and the second magnet 803 become magnets of different levels, and under the action of the attraction of the magnets of different levels, the original first magnet 801 and the original second magnet 803 move toward the ac electromagnet 802, so that the curtain body 11 is restored to the initial state, and the curtain body 11 is completely closed. And continuing to open, and repeatedly executing the process.
