Description

Technical Field

[0001] The present invention relates to the technical field of electric curtains, and particularly to an intelligent fully automatic electric curtain. Background Art

[0002] With the rapid development of social economy, Internet technology has entered our daily life. Smart home is an application result of Internet technology in the field of daily life. Smart home usually includes various smart home devices, a control system for controlling smart home devices, and a user smart terminal. The above three are connected through Internet technology to cooperate with each other. Smart home represents the mainstream lifestyle in the Internet era. Electric curtain is an important part of smart home. It uses an electric device to achieve automatic control of the curtain, eliminating the inconvenience brought by manual control of the curtain. Most of the existing electric curtains can only move the curtain left and right to open and close, and cannot perform up and down movement processing on the curtain. When the user needs to replace and clean the curtain, it is necessary to climb up a ladder to take down the curtain. During installation, it is necessary to climb up again for installation processing. It is not very convenient for a single person to operate during installation. For this reason, we have proposed an intelligent fully automatic electric curtain. Summary of the Invention

Both sides inside the curtain operation box 2 are fixedly connected with restraint hooks 12. One end of the curtain is placed on the traction hook 8, and the movement of the moving block 7 drives the curtain to stretch and contract through the traction hook 8.

[0035] Embodiment 2

[0036] Refer to Figures 4-5 : This embodiment provides a technical solution on the basis of Embodiment 1: The lifting mechanism further includes steel wires 15 wound around two winding wheels 14. Two connecting blocks 16 are fixedly connected to the top of the curtain operation box 2. One end of the steel wire 15 is fixedly connected to the connecting block 16. The rotation of the winding wheel 14 drives the winding of the steel wire 15, and at the same time drives the up and down movement of the curtain operation box 2 for processing.

[0037] Refer to Figures 3-4 : In the present invention, the transmission mechanism includes a worm 22 rotatably connected to the inside of the fixed mounting box 1. One end of the connecting rod 13 is fixedly sleeved with a worm gear 17. One side of the worm gear 17 is meshed and driven with the worm 22. A first bevel gear is fixedly sleeved on the drive rod 4. A second bevel gear 23 is fixedly sleeved on the worm 22. One side of the second bevel gear 23 is meshed and driven with the first bevel gear. The rotation of the drive rod 4 drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the synchronous rotation of the second bevel gear 23 for processing. The rotation of the second bevel gear 23 drives the rotation of the worm 17 for processing.

[0038] Refer to Figures 1-2 and Figure 6 : In the present invention, a plurality of mounting holes are arrayed and opened at the top of the fixed mounting box 1. The outer side of the curtain operation box 2 is closely attached to the inside of the fixed mounting box 1. A staggered tooth disc 24 is provided on one side of the worm 22. The staggered tooth disc 24 cuts off one side of the worm 22. The movement of the rotation of the worm is limited through the staggered tooth disc 24. The curtain operation box 2 is fixed through the close attachment of the curtain operation box 2 and the fixed mounting box 1.

[0039] Working principle: When in use, hang the curtain on the traction hook 8, auxiliary hook 10 and restraint hook 12 in sequence. When the drive motor 3 starts to rotate forward, it drives the drive rod 4 to rotate. The rotation of the drive rod 4 drives the synchronous rotation of the second pulley 5 and the first bevel gear. When the first bevel gear meshes and rotates with the second bevel gear 23, since the wire rope 15 has been completely wound by the winding wheel 14, and at the same time the top of the curtain operation box 2 abuts against the lower part inside the fixed installation box 1, the connecting rod 13 cannot continue to rotate, causing the meshing staggered tooth discs 24 to separate, so the worm 22 remains stationary. The rotation of the second pulley 5 drives the rotation of the first pulley 19 through the belt 20. The rotation of the first pulley 19 drives the rotation of the transmission rod 18. The rotation of the transmission rod 18 drives the rotation of the second gear 21. The rotation of the second gear 21 drives the rotation of the first gear 11. When the rotation of the first gear 11 drives the rotation of the bidirectional reciprocating lead screw 6, the rotation of the bidirectional reciprocating lead screw 6 drives the two moving blocks 7 to move smoothly along the guide rod 9 at the same time. When the movement of the moving block 7 drives the movement of the traction hook 8, the movement of the traction hook 8 drives the movement of a corner of the curtain. When the two moving blocks 7 move to the middle of the bidirectional reciprocating lead screw 6, the curtain is pulled up. When the two moving blocks 7 move to both ends of the bidirectional reciprocating lead screw 6, the curtain is opened;

[0040] When the curtain needs to be replaced and cleaned, the drive motor 3 starts to rotate in the reverse direction to drive the drive rod 4 to rotate in the reverse direction. When the drive rod 4 rotates in the reverse direction, it drives the first bevel gear and the second pulley 5 to move synchronously in the reverse direction. When the first bevel gear rotates in the reverse direction, it meshes and rotates with the second bevel gear 23. Through the engagement of the staggered tooth discs 24, when the second bevel gear 23 rotates, it drives the rotation of the worm 22. The rotation of the worm 22 is meshed and transmitted with the worm gear 17. The rotation of the worm gear 17 drives the rotation of the connecting rod 13. The rotation of the connecting rod 13 drives the rotation of the two winding wheels 14. The rotation of the winding wheel 14 relaxes the wire rope 15 downward. At the same time, due to gravity, the curtain operation box 2 moves downward synchronously. When the curtain operation box 2 moves downward, it drives the curtain to move downward synchronously. When the curtain operation box 2 is lowered, it is convenient for the operator to replace the curtain. After replacement, the drive motor 3 starts to rotate forward to drive the rotation of the worm 22. When the worm 22 rotates, it drives the worm gear 17 to rotate synchronously. When the worm gear 17 rotates, it drives the connecting rod 13 to rotate. The rotation of the connecting rod 13 drives the winding wheel 14 to wind the wire rope 15. When the wire rope 15 is wound, it drives the curtain operation box 2 to move upward synchronously, and at the same time pulls the replaced curtain upward, effectively improving the efficiency and effect of quickly replacing the high curtain.

[0041] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered by the protection scope of the present invention.
