Specific embodiments

[0020] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0021] Embodiment 1, referring to the attached Figure 1 , an electric curtain provided by the present utility model with an integrated socket controller includes a curtain body 100, an external curtain controller 200, and a wireless remote control 300 used in conjunction with the external curtain controller 200. As shown in the attached Figure 2 , the curtain body 100 includes a curtain storage bin. A first fixing block 110 and a second fixing block 120 are respectively arranged on both sides of the curtain storage bin. The first fixing block 110 is fixedly connected with a rotating shaft driving motor 130. An automatic reset rotating shaft 180 is arranged on one side of the rotating shaft driving motor 130. A power control line 230 is wound around the automatic reset rotating shaft 180. The automatic reset rotating shaft 180 belongs to the prior art and uses elastic members such as springs to achieve the elastic reset of the rotating shaft. In this way, when the power control line 230 is not affected by external forces, it can be automatically stored on the automatic reset rotating shaft 180. The rotating shaft driving motor 130 is drivingly connected with a curtain driving rotating shaft 140. A curtain winding shaft 150 is sleeved outside the curtain driving rotating shaft 140. The curtain winding shaft 150 is hollow. Two rotating shaft driving wheels 141 are fixedly arranged at intervals along the axial direction of the curtain driving rotating shaft 140. The rotating shaft driving wheels 141 are in contact with the inner side wall of the curtain winding shaft 150. The rotating shaft driving wheels 141 drive the curtain winding shaft 150 to rotate through friction. The projection curtain 160 is wound around the curtain winding shaft 150. The second fixing block 120 is provided with a support bearing 170. One end of the curtain winding shaft 150 away from the rotating shaft driving motor 130 is rotatably connected with the second fixing block 120 through the support bearing 170. The support bearing 170, as an auxiliary fulcrum, can increase the stability of the curtain winding shaft 150 during rotation; as shown in the attached Figure 3As shown in the figure, the external curtain controller 200 includes a controller housing 210. A control circuit board 220 is arranged inside the controller housing 210. The control circuit board 220 includes a single-chip microcomputer, a forward rotation relay, and a reverse rotation relay. The control circuit board 220 is electrically connected to the shaft drive motor 130 through a power control line 230. The forward rotation relay and the reverse rotation relay respectively control the forward and reverse rotations of the shaft drive motor 130, so as to realize the rising and falling of the projection curtain 160. The controller housing 210 is provided with a power plug 211 and three control buttons 213. The three control buttons 213 are respectively an up button, a down button, and a stop button. The controller housing 210 is provided with several status indicator lights 212 on one side of the control buttons 213. The status indicator lights 212 and the control buttons 213 are both electrically connected to the single-chip microcomputer. The status indicator lights 212 can display the working status of the projection curtain 160 by being electrically connected to the single-chip microcomputer. Especially when an error occurs, it can help the user confirm in the first time. The power plug 211 is electrically connected to the control circuit board 220. The power plug 211 supplies power to the shaft drive motor 130 through the control circuit board 220. And the wireless remote control 300 adapted to the external curtain controller 200 is provided with a control end wireless radio frequency chip. The control circuit board 220 is provided with a driving end wireless radio frequency chip adapted to the operation end wireless radio frequency chip. The driving end wireless radio frequency chip is electrically connected to the single-chip microcomputer. The wireless remote control 300 notifies the projection curtain 160 wirelessly, which is more convenient.

[0022] In some of these embodiments, a magnetizable metal block 240 is arranged inside the controller housing 210. The first fixing block 110 is fixedly connected with a controller adsorption magnet 190 adapted to the magnetizable metal block 240. In this way, when the electric curtain is in a non-working state, the power control line 230 is received by the automatic reset shaft 180, and at the same time, the external curtain controller 200 is magnetically adsorbed on the curtain body 100. This can better protect the components when the electric curtain is moving and stored, and reduce accidental bumps and the like.

[0023] The working principle of this embodiment is as follows:

[0024] When the electric screen is not in use, the screen rotates around the shaft 150 to control the projection screen 160 to rise and be stored in the screen storage bin. The power plug 211 of the external screen controller 200 is separated from the socket. At this time, the power control line 230 automatically winds around and is stored on the automatic reset rotating shaft 180, and the external screen controller 200 is adsorbed to the outside of the screen storage bin through the cooperation of the magnetizable metal block 240 and the controller adsorption magnet 190, so that it can be conveniently stored or moved; when the electric screen is in use, only need to pull out the power control line 230, insert the power plug 211 of the external screen controller 200 into the socket to start power supply, and then the rising, falling and stopping operations of the projection screen 160 can be completed through the control button 213 or the wireless remote control 300.

[0025] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation to the protection scope of the present invention: the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0026] The above is only the preferred embodiment of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present invention falls within the scope of protection required by the present invention.
