[0051] In the embodiment, the transmission guide mechanism and the sliding block 200 are both provided with two, which are located at two sides of the curtain cloth 100.

[0052] Preferably, in the embodiment, the cable 600 is arranged as a single-sided closed loop, and the specific implementation manner is that the fixed end is two disconnected ends of the cable 600, the two ends are fixed on the sliding block 200 by limiting, and the cable 600 forms a closed loop.

[0055] In the embodiment, the wire turning wheel 400 is preferably a straight wire turning wheel.

[0056] In the embodiment, the transmission guide mechanism further comprises a sliding rail 700 arranged between the wire turning wheel 400 and the guide wheel 500, and the sliding rail 700 is provided with a sliding groove 701 capable of accommodating the slider 200.

[0057] The slider 200 is limited in the sliding groove 701 and slides along the sliding groove 701, thereby ensuring the unfolding position of the curtain fabric 100.

[0058] In the embodiment, the sliding rail 700 is further provided with a cable groove 702 in the same direction as the sliding groove 701, and the cable 600 passes around the wire turning wheel 400 and the guide wheel 500, and the part between the wire turning wheel 400 and the guide wheel 500 is limited in the sliding groove 701 and the cable groove 702, respectively.

[0059] With reference to the drawings Figure 5 As shown, in the embodiment, the cross section of the sliding rail 700 is approximately S-shaped, and is formed with two grooves, namely the sliding groove 701 and the cable groove 702. In the embodiment, the sliding groove 701 and the cable groove 702 are arranged in an upper-lower manner, and after the cable 600 forms a closed loop, two symmetrical cable areas are formed between the wire turning wheel 400 and the guide wheel 500, and the two areas are arranged in the sliding groove 701 and the cable groove 702 and are limited in the grooves.

[0060] In the embodiment, in order to ensure the unfolding tension of the curtain fabric 100 and avoid wrinkles of the unfolded curtain fabric 100, the movable end of the curtain fabric 100 is provided with a sliding rod 800, and the slider 200 is assembled at both ends of the sliding rod 800 to drive the sliding rod 800 to slide together. Meanwhile, the sliding rail 700 is further provided with a curtain fabric groove 703 capable of accommodating the side end of the curtain fabric 100.

[0061] The two sides of the curtain fabric 100 are clamped into the curtain fabric groove 703, and the slide rail 700, the slide rod 800 and the winding pipe assembly 300 form a rigid support in quadrilateral shape, so that the four sides of the curtain fabric 100 are pulled tight, and the curtain fabric 100 is in a tension state when it is unfolded, and can cover the sunroof.

[0062] Specifically, referring to Figure 5 As shown in the figure, the side of the slide rail 700 is provided with an extension segment 710 on the side of the curtain fabric 100, and the end of the extension segment 710 is bent upward to form a top rib 711, and at the same side of the slide rail 700 and the extension segment 710, a limiting segment 720 is arranged, and the curtain fabric groove 703 is located between the limiting segment 720 and the extension segment 710.

[0063] When the side of the curtain fabric 100 is installed into the curtain fabric groove 703, it passes over the upper end of the top rib 711, and the top rib 711 holds the curtain fabric 100, so that the side of the curtain fabric 100 is in tension.

[0064] In this embodiment, the specific implementation of the winding pipe assembly 300 is that the winding pipe assembly 300 comprises a disc tensioning assembly for tensioning the rotating wire reel 400, and the disc tensioning assembly is always in a loaded state when the curtain fabric 100 is in an unfolded or stored state.

[0065] During the unfolding process, the disc tensioning assembly is always in a loaded state, that is, the disc tensioning assembly has a torsional force on the winding pipe assembly 300 and the rotating wire reel 400 at both ends, so that the rotating wire reel 400 is in a pre-tightened state relative to the winding pipe assembly, and maintains a consistent rotation rate during rotation.

[0066] If the rotation rates of the rotating wire reel 400 and the winding pipe assembly 300 are inconsistent, the traction speed of the cable 600 and the release speed of the curtain fabric 100 will be inconsistent, the traction speed of the cable 600 is too fast, which will cause the curtain fabric 100 to fail to keep up with the movement of the sliding block 200, resulting in jamming, and the release speed of the curtain fabric 100 is too fast, which will cause the released curtain fabric 100 to be excessively wrinkled.

[0067] Preferably, in this embodiment, the torsional force of the disc tensioning assembly on the rotating wire reel 400 and the winding pipe assembly 300 is in opposite directions.

[0068] Preferably, in this embodiment, the disc tensioning assembly comprises an outer pipe 310 winding the curtain fabric 100 and a tensioning spring 320, and the tensioning spring 320 is connected to the outer pipe 310 and the rotating wire reel 400, respectively.

[0069] One end of the tension spring 320 is fixed to the outer tube 310, and the other end is fixed to the line turning wheel 400. When assembled, the tension spring 320 is twisted at a certain angle, so that the line turning wheel 400 and the outer tube 310 have a torsional force in the initial state, so that the outer tube 310 and the line turning wheel 400 are kept in a tension state in any state.

[0070] Specifically, the outer tube 310 is coaxially provided with an inner tube 330, and the end of the inner tube 330 is connected with the line turning wheel 400 and is driven by the line turning wheel 400.

[0071] The two ends of the tension spring 320 are fixed on the inner tube 330 and the outer tube 310 respectively.

[0072] Specifically referring to Figure 6 As shown, the line turning wheel 400 is provided with two, and at least one is connected with the motor 2; at the same time, the end of the inner tube 330 is fixed or position-limiting connected with the line turning wheel 400, when the line turning wheel 400 rotates, it drives the inner tube 330 to rotate at the same angular velocity.

[0073] At the same time, referring to Figure 7 As shown, in the embodiment, two fixing seats 340 are arranged between the inner tube 330 and the outer tube 310, and the fixing seat 340 has a pipe hole 341 with an inner diameter consistent with the outer diameter of the inner tube 330, which can be sleeved on the inner tube 330 and fixed with the inner tube 330, and the shape of the fixing seat 340 is stepped, that is, the side away from the tension spring 320 is provided with a fixing ring 342, the outer diameter of the fixing ring 342 is consistent with the inner tube 330, and the fixing ring 342 can be fixed with the inner wall of the outer tube 310, and the spring fixing convex 343 is arranged on the outer periphery of the body close to the spring side, and the end of the tension spring 320 can be fixed to the spring fixing convex 343.

[0074] The spring fixing convex 343 can select a convex part, and the end of the tension spring 320 is provided with a sleeve part, which is sleeved on the spring fixing convex 343, and a limiting plate is arranged at the outer end of the convex part to limit the sleeve part of the tension spring 320, so as to avoid the sleeve part from being pulled out of the convex part.

[0075] In the embodiment, a bushing 350 is further arranged between the inner tube 330 and the outer tube 310 to limit the inner tube 330 and the outer tube 310.

[0076] In order to ensure that the line speed of the cable 600 is consistent during unwinding or winding, so as to ensure that the winding speed and unwinding speed of the cord fabric 100 are uniform, the line turning wheel 400 in the embodiment is preferably a straight wheel.

[0077] In order to reduce the noise generated during use, the winding pipe assembly 300 further comprises a mute assembly, which comprises a mute inner layer 370 and a mute outer layer 360 arranged on the inner and outer sides of the tension spring 320 respectively.

[0078] With reference to the drawings Figure 6 As shown in the drawings, the mute outer layer 360 is arranged between the tension spring 320 and the inner wall of the outer pipe 310 and is closely arranged on the inner wall of the outer pipe 310; the mute inner layer 370 is arranged between the tension spring 320 and the outer wall of the inner pipe 330 and is closely arranged on the outer wall of the inner pipe 330.
