Referring to fig. 1 to 3, a shading adjustment system for a smart building according to a first embodiment of the present utility model includes a window frame 10, an electric curtain 20, an electromagnet 30, and a circuit assembly 40, wherein the window frame 10 is mounted on a building body, a window sash 11 and a mounting bar 50 positioned at a front side of the window sash 11 are provided at an inner side of the window frame 10, a window opener 12 is provided between the window sash 11 and the window frame 10, the mounting bars 50 are arranged in two and vertically spaced apart, and guide grooves 51 are provided at opposite sides of the two mounting bars 50.

The electric curtain 20 comprises a motor 21, a curtain 22, a curtain rod 23 and a scroll 24, wherein the motor 21 is arranged on a window frame 10 or a building main body, the motor 21 is arranged above a window sash 11, the scroll 24 is connected with an output shaft of the motor 21, the curtain 22 is wound on the scroll 24 so as to drive the motor 21 to be connected with the curtain 22, the curtain rod 23 is arranged at the bottom of the curtain 22, magnetic attraction pieces 231 are arranged at two ends of the curtain rod 23, and the magnetic attraction pieces 231 are arranged in corresponding guide grooves 51. The electromagnet 30 is located in the guide groove 51 and is provided in an energized demagnetizing configuration. The circuit assembly 40 includes a first switch 41 and a second switch 42, the window opener 12 is electrically connected to the first switch 41, the motor 21 and the electromagnet 30 are electrically connected to the second switch 42, and the first switch 41 and the second switch 42 are connected in parallel to a total switch.

When in the power-off state, the electromagnet 30 attracts and positions the magnetic attraction member 231. When the curtain cloth 22 needs to be adjusted, the motor 21 and the electromagnet 30 are electrified through the closing of the second switch 42, the operation of the motor 21 can control the retraction and the extension of the curtain cloth 22, and the electromagnet 30 is electrified to demagnetize at the moment, so that the magnetic attraction piece 231 can move freely; after the curtain cloth 22 is adjusted, the second switch 42 is turned off, and the electromagnet 30 is powered off to attract and position the magnetic attraction piece 231. When the window is required to be opened, the window opener 12 is electrified through the closing of the first switch 41, and the window opener 12 pushes the window sash 11 to be opened; after the window is opened, the first switch 41 is turned off, and the electromagnet 30 magnetically attracts the magnetic attraction member 231 to be positioned when the electromagnet is powered off, so that the curtain 22 and the curtain rod can be restricted from shaking and impacting the window frame 10 under the action of air flow, and the noise can be reduced.

Wherein, the first switch 41 and the second switch 42 are both remote control switches, and when in installation and use, the first switch 41 and the second switch 42 are both in communication connection with the main control panel. By this structure, wiring can be reduced, and on-off of the first switch 41 and the second switch 42 can be controlled in a centralized manner at one position, thereby realizing centralized intelligent control of opening and closing the window and folding and unfolding the curtain.

In this embodiment, the curtain rod 23 has a mounting hole 232 penetrating through both ends, and the magnetic attraction member 231 is inserted into an end of the mounting hole 232. A tension spring 25 is also arranged in the mounting hole 232, and two ends of the tension spring 25 correspond to the magnetic attraction pieces 231 connected with two ends of the curtain rod 23. When the electromagnet 30 is powered off, the magnetic force of the electromagnet 30 pulls the magnetic attraction piece 231 to move back to the curtain rod 23, so that the magnetic attraction piece 231 is attracted with the electromagnet 30, and the tension spring 25 is stretched; when the electromagnet 30 is electrified and demagnetized, the tension spring 25 pulls the magnetic attraction member 231 to move towards the curtain rod 23, so that a gap is formed between the magnetic attraction member 231 and the electromagnet 30, and the curtain rod 23 can move up and down conveniently.

Specifically, when the electromagnet 30 is electrified and demagnetized, the distance between the two opposite sides of the magnetic attraction pieces 231 is set to L1, the distance between the electromagnets 30 in the two guide grooves 51 is set to L2, L1 < L2, and the difference between L1 and L2 is 5-10mm.

In some cases, the curtain 22 is lowered a long distance, so that the distance between the curtain rod 23 and the reel 24 is large, and the middle part of the curtain 22 still can shake somewhat under the action of air flow, and a certain noise still can be generated when the curtain hits the window frame 10. In order to solve this problem, the present utility model also proposes a second embodiment, referring to fig. 4 to 5, which differs from the first embodiment in that: a guide hole 52 communicated with the guide groove 51 is formed in the outer side wall of the mounting strip 50, a pressing piece 53 is arranged in the guide hole 52 in a sliding mode, the pressing piece 53 is connected with an electromagnetic push rod 54, and the electromagnetic push rod 54 is mounted on the mounting strip 50; the circuit assembly 40 further includes a wire holder 43, an input end of the wire holder 43 is electrically connected to the second switch 42, and an output end of the wire holder is electrically connected to the electromagnetic push rod 54 and the electromagnet 30, respectively.

Wherein the input and output terminals of the wire holder 43 are connected to each other so that the current supplied through the second switch 42 can be distributed to the electromagnetic push rod 54 and the electromagnet 30 through the wire holder 43. When the electromagnetic push rod 54 is powered off, the electromagnetic push rod 54 pushes the pressing sheet 53 to move into the guide groove 51 so as to press the side edge of the curtain cloth 22 on the inner side wall of the guide groove 51; when the electromagnetic push rod 54 is energized, the electromagnetic push rod 54 pushes the presser 53 back to the guide hole 52 to avoid affecting the movement of the curtain 22.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
