Description

[0002] Electric roller blinds are a type of motorized roller blind mechanism powered by a tubular motor. They are operated by toggling a power switch or using a remote control, offering simple operation, quiet and stable performance, and represent an upgrade from manual roller blinds. Electric roller blinds are typically installed indoors, have a long service life, and are suitable for various environments.

[0003] Chinese patent CN222045625U discloses an electric sunshade roller blind structure.

[0028] Example 1, as Figures 1-5As shown, the present invention proposes an electric roller shutter structure, including a storage box 1, a feeding roller 3, a winding roller 7, a counterweight plate 11, a curtain fabric 13, and a clamping mechanism. The storage box 1 has a through hole 101 communicating with its interior. The feeding roller 3 is rotatably disposed within the storage box 1, and a motor A4 is mounted on the storage box 1 to drive the feeding roller 3 to rotate. A guide roller A5 corresponding to the feeding roller 3 is rotatably disposed within the storage box 1, and a speed measuring component A for monitoring the rotational speed of the guide roller A5 is mounted on the storage box 1. The winding roller 7 is rotatably disposed within the storage box 1, and a motor B8 is mounted on the storage box 1 to drive the winding roller 7 to rotate. A guide roller B9 corresponding to the winding roller 7 is rotatably disposed within the storage box 1, and a speed measuring component B for monitoring the rotational speed of the guide roller B9 is mounted on the storage box 1. Speed ​​measuring component A includes speed sensor A6, and speed measuring component B includes speed sensor B10; both speed sensor A6 and speed sensor B10 are rotational speed sensors, and the bodies of the rotational speed sensors are connected to the storage box 1; a main controller is installed inside the storage box 1, and motor A4, speed sensor A6, motor B8, and speed sensor B10 are all electrically connected to the main controller. An arc-shaped groove 111 is provided on the counterweight plate 11, and a guide roller C12 is rotatably installed in the arc-shaped groove 111. The body of the curtain fabric 13 is wound around the feed roller 3, and the movable end of the curtain fabric 13 passes through the guide roller A5, guide roller C12, and guide roller B9 in sequence before connecting to the take-up roller 7. The curtain fabric 13 is a multi-segment curtain fabric (including at least opaque and semi-transparent segments), and the light transmittance of each segment of the curtain fabric 13 is different, and the length of each segment with different light transmittance is greater than twice the maximum stroke of the counterweight plate 11. The clamping mechanism is mounted on the counterweight plate 11 and abuts against the frame in the working state. The clamping mechanism includes two clamping plates 16 and a drive assembly 17. The two clamping plates 16 are located at opposite ends of the counterweight plate 11. The drive assembly 17 is located within the counterweight plate 11 and drives the two clamping plates 16 to move synchronously away from or towards each other. The drive assembly includes a slide rod 171, a bidirectional lead screw 172, and a motor C173. The ends of the two slide rods 171 that are far apart are connected to the corresponding clamping plates 16, while the ends that are close together are inserted into and slidably connected to the counterweight plate 11. The bidirectional lead screw 172 is rotatably mounted within the counterweight plate 11. A sliding shuttle is fitted onto the threaded ends of the bidirectional lead screw 172, and the two sliding shuttles are connected to the corresponding slide rods 171. The motor C173 is mounted on the counterweight plate 11, and its output end is connected to the bidirectional lead screw 172. A wireless transceiver is installed on the storage box 1, and a wireless signal receiver, a sub-controller, and an energy storage battery are installed on the counterweight plate 11. The energy storage battery is electrically connected to the wireless signal receiver, the sub-controller, and the clamping mechanism. The sub-controller is electrically connected to the wireless signal receiver and the clamping mechanism. The sub-controller and the main controller are connected to each other through the wireless transceiver and the wireless signal receiver.A male plug 15 is vertically downward on the storage box 1, and a female plug 14 with an opening vertically upward is provided on the counterweight plate 11. The female plug 14 is electrically connected to the energy storage battery and is compatible with the male plug 15.

[0029] It should be noted that motors A4, B8 and C173 in this embodiment are all servo motors, and the main controller of this device is connected to the user terminal device (mobile phone, etc.).

[0030] In this embodiment, the storage box 1 is installed at the top of the window frame with the counterweight plate 11 facing downwards. The device is then powered on. At this time, the energy storage battery in the counterweight plate 11 is charged due to the cooperation of the male plug 15 and the female plug 14. When it is necessary to cover the window, the device is started by controlling the mobile phone APP. At this time, the motor B8 remains stationary, and the motor A4 drives the feeding roller 3 to rotate and start releasing the curtain 13. The counterweight plate 11, together with the guide roller C12, drives the curtain 13 downwards and covers the window in a double-sided manner. When the curtain 13 is released, the speed sensor A6 measures the height of the curtain based on the speed and number of rotations of the guide roller A5 driven by the curtain 13. When the counterweight 11 reaches the set point, the motor A4 stops rotating, and the motor C173 drives the bidirectional lead screw 172 to rotate. The two shuttles push the corresponding slide rods 171 to slide, so that the two side plates 16 move away synchronously until they abut against the side of the window frame, thereby preventing the curtain 13 from swinging due to the wind. When it is necessary to change the blocking effect of different light transmittance, motors A4 and B8 start synchronously to realize the simultaneous feeding and winding of the curtain 13. The speed of feeding and winding of the curtain is measured synchronously by speed sensors A6 and B10, and the output speed of motors A4 and B8 is controlled by the main controller to achieve synchronous feeding and winding of both ends of the curtain.

[0031] Example 2, as Figure 2 As shown, the electric roller shutter structure proposed in this utility model, compared with the first embodiment, has a partition plate 2 centrally arranged in the through hole 101, and flexible brushes are arranged on both sides of the partition plate 2 and on the inner wall of the through hole 101.

[0032] Using a flexible brush to gently clean the surface of the curtain 3 that runs along its two side channels can remove dust from the surface of the curtain 3 and prevent dust from entering the storage box 1.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
