[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0016] like Figure 1-4 The double-layer curtain roller blind structure shown includes a curtain cover 1, a day blind 2, and a night blind 3. The rollers 4 of the day blind 2 and the night blind 3 are rotatably mounted relative to the curtain cover 1, and the day blind 2 and the night blind 3 are equipped with independent rolling control systems. The bottom of the day blind 2 and the night blind 3 are respectively equipped with counterweight beams 5. The day blind 2 includes a mesh layer 21 and a fabric layer 22, and the day blind 2 is rolled up in a double-layer configuration at the counterweight beam 5. The height of a single unit of the fabric layer 22 is greater than the height of a single unit of the mesh layer 21. The fabric layer 22 can be used to cover the transparent mesh of the mesh layer 21. The night blind 3 adopts a three-layer composite structure, which is a full-light-blocking fabric made by composite thermoplastic polyurethane elastomer material in the middle of the double-layer fiber woven layers on both sides.

[0017] As described above, in this embodiment of the double-layer curtain roller blind structure, an independent double-axis roller 4 is installed within a set of curtain covers 1 for hanging the day curtain 2 and the night curtain 3. As mentioned above, the day curtain 2 in this embodiment adopts a double-layer non-fabricated curtain structure. (Refer to...) Figure 3 The day blind 2 shown is designed in the style of a Roman blind. The mesh layer 21 has perforations between the light-transmitting fabric layer 22. When the two mesh layers 21 are facing each other, they allow for better access to outdoor light. When the fabric layer 22 is facing the mesh layer 21, it forms a double-layered semi-transparent fabric layer 22 that blocks direct sunlight. When complete blackout is needed, simply lower the night blind 3. The fabric with a thermoplastic polyurethane elastomer interlayer provides a light-blocking effect, ensuring that no light from inside or outside the window can pass through, whether at night or day. This allows users to... This utility model's roller blind structure allows for full light and view transmission when both roller blinds are rolled up. When the day blind 2 is lowered, the offset of the double-layered fabric allows switching between light transmission and semi-transparency. Lowering the night blind 3 provides complete blackout. This multi-functional design is highly practical. Furthermore, in this embodiment, the double-layered roller blinds are offset in height, making it easier to roll up the fabric, saving space and preventing friction and interference. In terms of usage, this embodiment also provides multiple control methods, including manual (beaded chains, etc.) and electric (remote control or voice control) control, similar to existing technologies.

[0018] As a further provision of the above scheme, the upper end of the curtain cover 1 is provided with a mounting bracket fixing groove 6, and the two sides of the curtain cover 1 are provided with cover plates 61 with mounting blocks 62 that engage in the mounting bracket fixing groove 6. The rollers 4 of the day curtain 2 and the night curtain 3 are arranged sequentially in a vertical direction relative to the curtain cover 1, and the roller 4 of the night curtain 3 is located above the roller 4 of the day curtain 2 and is offset towards the rear side of the curtain cover 1. Figure 3 As shown, in this embodiment, the cover plates 61 on both sides of the curtain 1 are inserted into the mounting bracket fixing groove 6 of the curtain 1 by the provided mounting blocks 62. Then, the bolts are pushed in from above, and the mounting blocks 62 are over-tightened to make them fit into the mounting bracket fixing groove 6, which facilitates installation.

[0019] As a further provision of the above scheme, the counterweight beam 5 includes a retaining beam 51 for the daytime curtain 2 and a fabric-covering beam 52 for the nighttime curtain 3. The retaining beam 51 is provided with inserts 53, slots 58, counterweight bars 54, and counterweight adjustment grooves 55. The counterweight adjustment grooves 55 are also provided with two counterweight locking blocks 56, such as... Figure 3 and Figure 4 The night curtain 3 shown in this embodiment uses a single layer of fabric to wrap around the counterweight beam 5 and then secure it within the fabric-wrapping beam 52. The day curtain 2, being a double-layered single-fabric curtain, requires positional adjustment and is therefore configured as follows: Figure 3 and Figure 4The sleeve beam 51 shown is installed by fitting the fabric with insert 53 and then inserting the insert 53 into the slot 58. Since the sun curtain 2 is adjusted between two states, and the sun curtain 2 is more likely to be horizontal, the sleeve beam 51 is also provided with a counterweight bar 54 and a counterweight block 56 that is easy to disassemble and install and restricts the position of the counterweight bar 54 to fix its position. As shown in the figure, the counterweight block 56 can be flipped and inserted relative to the counterweight adjustment groove 55 during use. After being inserted, it is located on both sides of the counterweight bar 54 to form a fixed position. When disassembling, it can be flipped on one side.

[0020] As a further feature of the above solution, the winding control system includes a winding motor and a control unit. The control unit is equipped with a remote control component and a remote controller 8. The remote controller 8 includes a detachable keypad 81, which is snapped onto the remote controller 8.

[0021] Furthermore, when the roller blind is electrically controlled, the existing electric remote control technology often encounters the problem of incorrect direction. This is usually due to wiring or motor installation direction after maintenance or disassembly, which causes the down button and up button on the remote control to be reversed, resulting in inconvenience. Therefore, this embodiment provides a remote control 8 that matches the day and night double-layer electric roller blind. When the user finds that the button and the curtain retraction state are inconsistent, the up and down direction can be adjusted by disassembling and rotating the detachable keypad 81 relative to the remote control 8 and then reinstalling it. This ensures that the button indication pattern is the same as the actual control setting.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
