[0037] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0038] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a sunroof sunshade structure, including a frame 1, a curtain 2, a curtain beam 3, a curtain shaft 4, a power mechanism 14 and a transmission mechanism, the curtain 2 has a first side and a second side opposite to each other in its winding direction, the first side of the curtain 2 is connected to the curtain beam 3, the second side of the curtain 2 is connected to the curtain shaft 4, and the curtain shaft 4 can rotate around its axis.

[0039] like Figure 4As shown, the transmission mechanism includes a slider 8, a first cable 6, a second cable 7 and a winding wheel 5. The slider 8 is fixed on the curtain crossbeam 3 and slidably connected to the frame 1. The winding wheel 5 is installed on the curtain shaft 4. One end of the first cable 6 is wound around the winding wheel 5, and the other end is connected to the slider 8. One end of the second cable 7 is wound around the winding wheel 5, and the other end is connected to the slider 8. The winding direction of the first cable 6 is opposite to the winding direction of the second cable 7.

[0040] The power mechanism 14 is used to drive the winding wheel 5 or the curtain shaft 4 to rotate forward and reversely, so that one of the first cable 6 and the second cable 7 is wound back while the other is released. When the first cable 6 is wound back, the slider 8 is pulled to slide away from the curtain shaft 4 to drive the curtain 2 to open, and when the second cable 7 is wound back, the slider 8 is pulled to slide toward the curtain shaft 4 to drive the curtain 2 to retract.

[0041] Specifically, Figure 1 As shown, for example, when the curtain 2 needs to be rolled up, the power mechanism 14 drives the winding wheel 5 or the curtain shaft 4 to rotate forward, the first cable 6 wound on the winding wheel 5 is released, and the second cable 7 is reeled in, the length of the second cable 7 released becomes shorter, and the slider 8 is pulled on the frame 1 to slide toward the curtain shaft 4. At the same time, the length of the first cable 6 released becomes longer, and the first cable 6 releases the slider 8 to slide toward the side close to the curtain shaft 4, and the slider 8 fixed on the curtain crossbeam 3 drives the first side of the curtain 2 to move toward the side close to the curtain shaft 4, and the curtain shaft 4 rotating forwardly rolls up the curtain 2.

[0042] When the curtain 2 needs to be unfolded, Figure 2 and Figure 6 As shown, the power mechanism 14 drives the winding wheel 5 or the curtain shaft 4 to reverse, the first cable 6 wound on the winding wheel 5 is rewound, and the second cable 7 is released, the length of the released first cable 6 becomes shorter, and the slider 8 is pulled on the frame 1 to slide away from the curtain shaft 4. At the same time, the length of the released second cable 7 becomes longer, and the second cable 7 releases the slider 8 to slide away from the curtain shaft 4. The slider 8 drives the curtain beam 3 to move synchronously, and the curtain beam 3 drives the first side of the curtain 2 to move when the reversed curtain shaft 4 rotates, so that the curtain 2 gradually opens.

[0043] Of course, the power mechanism 14 can drive the first cable 6 to rewind and the second cable 7 to release during forward rotation, and can drive the first cable 6 to release and the second cable 7 to rewind during reverse rotation.

[0044] In the sunroof sunshade structure of the utility model, when the power mechanism 14 drives the winding wheel 5 or the curtain shaft 4 to rotate forward and reverse, one of the first cable 6 and the second cable 7 is released while the other is rewound, and the rewound first cable 6 can pull the slider 8 to slide in the direction away from the curtain shaft 4, and the slider 8 drives the curtain crossbeam 3 to move synchronously, and the curtain crossbeam 3 drives the first side of the curtain 2 to move, so that the curtain 2 is opened when the curtain shaft 4 rotates, and the rewound second cable 7 can pull the slider 8 to slide in the direction close to the curtain shaft 4, so that the curtain shaft 4 rotating in the opposite direction rewinds the curtain 2. The sunroof sunshade structure realizes the opening and rewinding of the curtain 2 by the conversion of the first cable 6 and the second cable 7 on the winding wheel 5, and eliminates the use of parts such as flexible shafts and coil springs in related technologies, thereby avoiding the problem that the sunroof sunshade using flexible shafts is prone to noise.

[0045] In one embodiment, if Figure 1 As shown, the frame 1 includes a guide rail 11 extending along the retracting direction of the curtain 2, and the slider 8 is slidably connected to the guide rail 11. Specifically, a slide groove extending along the retracting direction of the curtain 2 is provided on the guide rail 11, and the slide groove wraps the bottom of the slider 8, so that when the first cable 6 or the second cable 7 pulls the slider 8, the slider 8 is guided to slide in the slide groove to avoid tilting when the slider 8 slides.

[0046] In one embodiment, two guide rails 11 are provided, and the two guide rails 11 are provided on both sides of the frame 1 along the left-right direction, wherein the winding direction of the curtain 2 is the front-to-back direction, and on the plane where the curtain 2 is located, the direction perpendicular to the winding direction of the curtain 2 is the left-right direction.

[0047] In one embodiment, two transmission mechanisms are provided, and the two transmission mechanisms are arranged oppositely on two sides of the frame 1 along the left-right direction.

[0048] The slider 8 of the left transmission mechanism is fixed to the left end of the curtain fabric cross beam 3 and is slidably connected to the left guide rail 11. The slider 8 of the right transmission mechanism is fixed to the right end of the curtain fabric cross beam 3 and is slidably connected to the right guide rail 11.

[0049] The winding wheel 5 of the transmission mechanism on the left is installed at the left end of the cord shaft 4 , and the winding wheel 5 of the transmission mechanism on the right is installed at the right end of the cord shaft 4 .

[0050] One end of the first cable 6 of the left transmission mechanism is wound around the winding wheel 5 of the left transmission mechanism, and the other end is connected to the slider 8 of the left transmission mechanism. One end of the second cable 7 of the left transmission mechanism is wound around the winding wheel 5 of the left transmission mechanism, and the other end is connected to the slider 8 of the left transmission mechanism.

[0051] The first cable 6 of the transmission mechanism on the right side is wound around the winding wheel 5 of the transmission mechanism on the right side, and the other end is connected to the slider 8 of the transmission mechanism on the right side. The second cable 7 of the transmission mechanism on the right side is wound around the winding wheel 5 of the transmission mechanism on the right side, and the other end is connected to the slider 8 of the transmission mechanism on the right side.

[0052] When the power mechanism 14 outputs power, the slider 8 of the transmission mechanism on the left and the slider 8 of the transmission mechanism on the right simultaneously drive the curtain beam 3 to move, and both sides of the curtain beam 3 are subjected to tension, so that the movement of both ends of the curtain beam 3 is more synchronized.

[0053] In one embodiment, if Figure 5 As shown, the transmission mechanism also includes a first spring 15 and a second spring 16. The slider 8 is provided with a first fixed groove and a second fixed groove located at the rear side of the first fixed groove. The first spring 15 is pressed into the first fixed groove, and the second spring 16 is pressed into the second fixed groove. The other end of the first cable 6 is connected to the first spring 15, and the other end of the second cable 7 is connected to the second spring 16.

[0054] The first cables 6 of the transmission mechanism on the left and right sides are pre-tensioned by the first spring 15, and the second cables 7 are pre-tensioned by the second spring 16, so that the first cables 6 on the left and right sides can adjust the tension on the slider 8 through the first spring 15, and the second cables 7 on the left and right sides can adjust the tension on the slider 8 through the second spring 16, which is beneficial to the left and right balance during the movement of the curtain beam 3.

[0055] It should be noted that the orientation “rear” refers to the direction in which the curtain 2 is rolled up, and “front” refers to the direction in which the curtain 2 is opened.

[0056] In one embodiment, the bottom side of the first fixing groove has an opening, the first spring 15 is pressed into the first fixing groove through the opening, and the two ends of the first spring 15 respectively abut against the front and rear side walls of the first fixing groove. The bottom side of the second fixing groove has an opening, the second spring 16 is pressed into the second fixing groove through the opening, and the two ends of the second spring 16 respectively abut against the front and rear side walls of the second fixing groove.

[0057] In one embodiment, the slider 8 is provided with a slot with an opening facing one side of the curtain 2, and the curtain cross beam 3 is inserted into the slot.

[0058] In one embodiment, the frame 1 also includes a front crossbeam 12 and a rear crossbeam 13. The left guide rail 11 is connected between the left end of the front crossbeam 12 and the left end of the rear crossbeam 13. The right guide rail 11 is connected between the right end of the front crossbeam 12 and the right end of the rear crossbeam 13. The two guide rails 11 are components of the frame 1, and there is no need to set up additional longitudinal beams, thereby reducing the weight of the frame 1.

[0059] The power mechanism 14 is mounted on the rear cross beam 13 .

[0060] It should be noted that the slide groove on the guide rail 11 can be formed when the guide rail 11 is stamped.

[0061] In one embodiment, if Figure 3 and Figure 4 As shown, the power mechanism 14 is installed at the right end of the rear cross beam 13, and the power of the power mechanism 14 is output to the winding wheel 5 of the transmission mechanism on the right side. The winding wheel 5 of the transmission mechanism on the left side is rotatably supported on the left end of the rear cross beam 13, so that the winding wheels 5 on the left and right sides are driven to rotate by only one power mechanism 14, thereby reducing the power mechanism 14 and reducing the cost and weight.

[0062] In one embodiment, the rotating shaft of the winding wheel 5 is connected to the end of the curtain shaft 4 through a spline, and the power mechanism 14 is transmission-connected to the winding wheel 5 on the right side. When the power mechanism 14 outputs power, the power mechanism 14 drives the winding wheel 5 on the right side to rotate, and the curtain shaft 4 rotates synchronously with the winding wheel 5 on the right side, and the curtain shaft 4 then drives the winding wheel 5 on the left side to rotate.

[0063] In one embodiment, the power mechanism 14 is a motor, a transmission gear is fixed on the rotating shaft of the winding wheel 5, and the driving gear of the motor is meshed with the transmission gear.

The other end of the first cable 6 is connected to the slider 8 after bypassing the steering member. The direction of the first cable 6 is controlled by the steering member, which is beneficial to controlling the direction in which the first cable 6 pulls the slider 8, thereby improving the success rate of the sunroof sunshade structure to open the curtain 2.

[0066] In one embodiment, the steering member is rotatably mounted on the frame 1, and a rotation centerline of the steering member has a non-zero angle with the sliding direction of the slider 8. When the first cable 6 is released or rewound, the steering member rotatably mounted on the frame 1 can rotate to reduce the friction between the first cable 6 and the steering member, thereby increasing the effective service life of the first cable 6.

[0067] In one embodiment, the steering member is a fixed pulley 9, and a circumferential groove and a rotating groove are provided on the outer wall of the fixed pulley 9. The circumferential groove extends along the circumferential direction of the fixed pulley 9, and the rotating groove spirally extends around the rotation center line of the fixed pulley 9 and is connected to the circumferential groove.
