[0002] The present application belongs to the technical field of vehicle parts, in particular relates to a sunroof sunshade curtain structure and vehicle. BACKGROUND

[0003] The sunroof sunshade curtain on the vehicle can block the light outside the sunroof when it is opened. In the related art, the opening and closing of the sunroof sunshade curtain is realized by relying on a motor to drive a flexible shaft (connected to the front end of the sunshade curtain fabric) and a coiled spring or spring structure on the roller tube.

[0028] In the skylight sunshade structure of this application, when the power mechanism drives the winding wheel or curtain shaft to rotate forward and backward, one of the first and second pull cables is released while the other is rolled back. The rolled-back first pull cable can pull the slider to slide away from the curtain shaft, and the slider drives the curtain beam to move synchronously. The curtain beam drives the first side of the curtain to move, so that the curtain opens when the curtain shaft rotates. The rolled-back second pull cable can pull the slider to slide closer to the curtain shaft, so that the rotating curtain shaft rolls the curtain back up. This skylight sunshade structure realizes the opening and rolling up of the curtain by changing the release and retraction of the first and second pull cables on the winding wheel, eliminating the use of flexible shafts, coil springs and other parts in related technologies, and avoiding the noise problem that skylight sunshades using flexible shafts are prone to generate.

[0037] Implementation methods of this application

[0038] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0039] As shown in Figures 1 and 2, one embodiment of this application provides a skylight sunshade structure 100, including a frame 1, a curtain fabric 2, a curtain beam 3, a curtain shaft 4, a power mechanism 14, and a transmission mechanism. The curtain fabric 2 has a first side and a second side opposite to each other in its retraction direction. The first side of the curtain fabric 2 is connected to the curtain beam 3. The second side of the curtain fabric 2 is connected to the curtain shaft 4. The curtain shaft 4 is rotatable about its axis.

[0040] As shown in Figure 4, 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 to the curtain beam 3 and slidably connected to the frame 1, and the winding wheel 5 is mounted 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 that of the second cable 7.

[0041] The power mechanism 14 is used to drive the winding wheel 5 or the curtain shaft 4 to rotate in both directions, so that when one of the first cable 6 and the second cable 7 is wound back, the other is unwound. When the first cable 6 is wound back, it pulls the slider 8 to slide away from the curtain shaft 4, thereby opening the curtain 2. When the second cable 7 is wound back, it pulls the slider 8 to slide closer to the curtain shaft 4, thereby winding the curtain 2 back up.

[0042] Specifically, as shown in Figure 1, for example, when it is necessary to roll up the curtain 2, the power mechanism 14 drives the winding wheel 5 or the curtain shaft 4 to rotate clockwise. The first pull cable 6 wound on the winding wheel 5 is released and the second pull cable 7 is wound back. The length of the second pull cable 7 that is released becomes shorter, pulling the slider 8 to slide on the frame 1 towards the direction closer to the curtain shaft 4. At the same time, the length of the first pull cable 6 that is released becomes longer, and the first pull cable 6 releases the slider 8 to slide towards the side closer to the curtain shaft 4. The slider 8 fixed on the curtain beam 3 drives the first side of the curtain 2 to move towards the side closer to the curtain shaft 4, while the clockwise rotating curtain shaft 4 rolls up the curtain 2.

[0043] When the curtain 2 needs to be unfolded, as shown in Figures 2 and 6, the power mechanism 14 drives the winding wheel 5 or the curtain shaft 4 to reverse, the first pull cable 6 wound on the winding wheel 5 is rewound, and the second pull cable 7 is released. The length of the released first pull cable 6 becomes shorter, pulling the slider 8 to slide away from the curtain shaft 4 on the frame 1; at the same time, the length of the released second pull cable 7 becomes longer, and the second pull 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. When the curtain shaft 4 rotates in reverse, the curtain beam 3 drives the first side of the curtain 2 to move, so that the curtain 2 gradually opens.

[0044] Of course, the power mechanism 14 can drive the first cable 6 to rewind and the second cable 7 to unwind when rotating forward, and drive the first cable 6 to unwind and the second cable 7 to rewind when rotating in reverse.

[0045] In the skylight sunshade structure 100 of this application, when the power mechanism 14 drives the winding wheel 5 or the curtain shaft 4 to rotate forward and backward, one of the first pull cable 6 and the second pull cable 7 is released while the other is rolled back. The rolled-back first pull cable 6 can pull the slider 8 to slide away from the curtain shaft 4. The slider 8 drives the curtain beam 3 to move synchronously. The curtain beam 3 drives the first side of the curtain 2 to move, so that the curtain 2 opens when the curtain shaft 4 rotates. The rolled-back second pull cable 7 can pull the slider 8 to slide closer to the curtain shaft 4, so that the curtain shaft 4, which rotates in the opposite direction, rolls up the curtain 2. This skylight sunshade structure 100 realizes the opening and rolling up of the curtain 2 by changing the rotation of the first pull cable 6 and the second pull cable 7 on the winding wheel 5, eliminating the use of flexible shafts, coil springs and other parts in related technologies, and avoiding the noise problem that skylight sunshades using flexible shafts are prone to generate.

[0046] In one embodiment, as shown in FIG1, the frame 1 includes a guide rail 11 extending along the winding direction of the curtain 2, and a slider 8 slidably connected to the guide rail 11. Specifically, the guide rail 11 is provided with a groove extending along the winding direction of the curtain 2, the groove covering the bottom of the slider 8, so that when the first pull cable 6 or the second pull cable 7 pulls the slider 8, the slider 8 is guided to slide within the groove, avoiding tilting of the slider 8 when it slides.

[0047] In one embodiment, two guide rails 11 are provided. The two guide rails 11 are provided on both sides of the frame 1 along the left-right direction. The winding direction of the curtain 2 is the front-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.

[0048] In one embodiment, two transmission mechanisms are provided, which are arranged opposite to each other on both sides of the frame 1 in the left-right direction.

[0049] The slider 8 of the transmission mechanism on the left is fixed to the left end of the curtain beam 3 and is slidably connected to the guide rail 11 on the left. The slider 8 of the transmission mechanism on the right is fixed to the right end of the curtain beam 3 and is slidably connected to the guide rail 11 on the right.

[0050] The winding wheel 5 of the transmission mechanism on the left is installed at the left end of the curtain shaft 4. The winding wheel 5 of the transmission mechanism on the right is installed at the right end of the curtain shaft 4.

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

[0052] The first cable 6 of the right-side transmission mechanism is wound around the winding wheel 5 of the right-side transmission mechanism, and the other end is connected to the slider 8 of the right-side transmission mechanism. The second cable 7 of the right-side transmission mechanism is wound around the winding wheel 5 of the right-side transmission mechanism, and the other end is connected to the slider 8 of the right-side transmission mechanism.

[0053] When the power mechanism 14 outputs power, the slider 8 of the left transmission mechanism and the slider 8 of the right transmission mechanism simultaneously drive the curtain beam 3 to move. Both sides of the curtain beam 3 are subjected to tension, making the movement of both ends of the curtain beam 3 more synchronized.

[0054] In one embodiment, as shown in FIG5, the transmission mechanism further includes a first spring 15 and a second spring 16. The slider 8 is provided with a first fixing groove and a second fixing groove located behind the first fixing groove. The first spring 15 is press-fitted into the first fixing groove, and the second spring 16 is press-fitted into the second fixing 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.

[0055] The first cable 6 of the transmission mechanism on the left and right sides is pre-tightened by the first spring 15 and the second cable 7 is pre-tightened by the second spring 16. Thus, the first cable 6 on the left and right sides can adjust the tension of the slider 8 by the first spring 15 and the second cable 7 on the left and right sides can adjust the tension of the slider 8 by the second spring 16, which is beneficial to the left and right balance during the movement of the curtain beam 3.

[0056] It should be noted that the "back" direction refers to the direction in which curtain 2 is rolled up, and the "front" direction refers to the direction in which curtain 2 is opened.

[0057] In one embodiment, the bottom side of the first fixing groove has an opening, and the first spring 15 is press-fitted into the first fixing groove through the opening, with its two ends abutting against the front and rear side walls of the first fixing groove, respectively. The bottom side of the second fixing groove has an opening, and the second spring 16 is press-fitted into the second fixing groove through the opening, with its two ends abutting against the front and rear side walls of the second fixing groove, respectively.

[0058] In one embodiment, the slider 8 is provided with a slot with an opening facing the side of the curtain 2, and the curtain beam 3 is inserted into the slot.

[0059] In one embodiment, the frame 1 further includes a front crossbeam 12 and a rear crossbeam 13. A left-side guide rail 11 connects the left end of the front crossbeam 12 to the left end of the rear crossbeam 13. A right-side guide rail 11 connects the right end of the front crossbeam 12 to the right end of the rear crossbeam 13. The two guide rails 11 are integral parts of the frame 1, eliminating the need for additional longitudinal beams and reducing the weight of the frame 1.

[0060] The power mechanism 14 is mounted on the rear crossbeam 13.

[0061] It should be noted that the grooves on the guide rail 11 can be formed during the stamping process of the guide rail 11.

[0062] In one embodiment, as shown in Figures 3 and 4, the power mechanism 14 is installed at the right end of the rear crossbeam 13. The power output of the power mechanism 14 is sent to the winding wheel 5 of the transmission mechanism on the right side, while the winding wheel 5 of the transmission mechanism on the left side is rotatably supported at the left end of the rear crossbeam 13. This reduces the number of power mechanisms 14, thereby lowering the cost and weight.

[0063] In one embodiment, the rotating shaft of the winding wheel 5 is connected to the end of the fabric shaft 4 via a spline, and the power mechanism 14 is connected to the winding wheel 5 on the right side via a transmission. When the power mechanism 14 outputs power, it drives the winding wheel 5 on the right side to rotate, and the fabric shaft 4 rotates synchronously with the winding wheel 5 on the right side. The fabric shaft 4 then drives the winding wheel 5 on the left side to rotate.

[0064] In one embodiment, the power mechanism 14 is a motor, and a transmission gear is fixed on the rotating shaft of the winding wheel 5. The driving gear of the motor meshes with the transmission gear.

[0065] In other embodiments, the power mechanism 14 can be installed at the left end of the rear crossbeam 13, and the power output of the power mechanism 14 is sent to the winding wheel 5 of the transmission mechanism at the left end, while the winding wheel 5 of the transmission mechanism on the right side is rotatably supported at the right end of the rear crossbeam 13.

[0066] In one embodiment, as shown in FIG5, the transmission mechanism further includes a steering component, which is installed on the side of the frame 1 away from the curtain shaft 4. The other end of the first pull cable 6 passes around the steering component and is connected to the slider 8. The direction of the first pull cable 6 is controlled by the steering component, which is beneficial to control the direction in which the first pull cable 6 pulls the slider 8, thereby improving the success rate of the sunroof sunshade structure 100 opening the curtain 2.

[0067] In one embodiment, the steering component is rotatably mounted on the frame 1, and the rotation center line of the steering component forms a non-zero angle with the sliding direction of the slider 8. When the first cable 6 is released or retracted, the steering component rotatably mounted on the frame 1 can rotate to reduce the friction between the first cable 6 and the steering component, thereby improving the effective service life of the first cable 6.

[0068] In one embodiment, the steering component is a fixed pulley 9, and the outer wall of the fixed pulley 9 is provided with a circumferential groove and a rotating groove. The circumferential groove extends along the circumference of the fixed pulley 9, and the rotating groove extends spirally around the rotation center line of the fixed pulley 9 and communicates with the circumferential groove. The rotating groove allows the first cable 6 to be wound into the circumferential groove so that the first cable 6 can be tightened and wound around the fixed pulley 9 during assembly.

[0069] In one embodiment, the rotation axis of the fixed pulley 9 is vertically fixed to the front end of the guide rail 11 on the right side, and the first end of the first cable 6 extends forward along the sliding direction of the slider 8, and extends backward after passing over the fixed pulley 9 to connect with the slider 8.

[0070] In one embodiment, as shown in FIG4, the transmission mechanism further includes a guide auxiliary wheel 10 rotatably mounted on the frame 1. The guide auxiliary wheel 10 and the winding wheel 5 are located on the same side of the frame 1, and the rotation center line of the guide auxiliary wheel 10 is parallel to the rotation center line of the winding wheel 5. The other end of the first pull cable 6 passes around the bottom of the guide auxiliary wheel 10 and extends in a direction away from the curtain shaft 4. The guide auxiliary wheel 10 is configured to guide the other end of the first pull cable 6 extending in a direction away from the curtain shaft 4, so as to prevent the other end of the first pull cable 6 from swinging left and right when the first pull cable 6 is wound back, thus affecting the pulling of the curtain beam 3.

[0071] In one embodiment, a single guide wheel 10 is provided, positioned close to the winding wheel 5. This guide wheel 10 guides the other end of the first cable 6 extending from the winding wheel 5, allowing the longer first cable 6 to extend along a predetermined direction. Of course, the installation position and number of guide wheels 10 can be adjusted according to actual needs.

[0072] In one embodiment, a limiting seat located behind the slider 8 is fixed on the guide rail 11 on the right side. The limiting seat and the slider 8 are arranged in the front-rear direction. The limiting seat is U-shaped and has a through opening. The other end of the second cable 7 passes through the limiting seat and is connected to the slider 8. The limiting seat limits the second cable 7 to the left and right.

[0073] In one embodiment, a support is fixed on the guide rail 11 on the right side. In the left-right direction, the support is located on the right side of the limiting seat. A support platform is provided on the right side wall of the limiting seat. A rotating groove with an upward opening is provided on the support platform. The left end of the rotating shaft of the guide auxiliary wheel 10 is installed in the rotating groove, and the right end of the rotating shaft is installed on the support.

[0074] In one embodiment, the winding wheel 5 is cylindrical. Specifically, the winding wheel 5 is provided with a spiral groove, and the first cable 6 and the second cable 7 are wound in the spiral groove. Compared with the inverted spiral winding wheel 5, the spiral groove of the cylindrical winding wheel 5 has the same radius, which can avoid the first cable 6 and the second cable 7 from coming off during the process of winding from the large diameter spiral groove to the small diameter spiral groove of the winding wheel 5, thereby improving the stability of the winding wheel 5.

[0075] In other embodiments, only one transmission mechanism may be provided, which is arranged on one side of the frame 1 in the left-right direction.

[0076] In other embodiments, frame 1 may include a left longitudinal beam, a right longitudinal beam, a front crossbeam 12, and a rear crossbeam 13. The left longitudinal beam connects the left end of the front crossbeam 12 and the left end of the rear crossbeam 13, the right longitudinal beam connects the right end of the front crossbeam 12 and the right end of the rear crossbeam 13, the left guide rail 11 is fixed to the left longitudinal beam, and the right guide rail 11 is fixed to the right longitudinal beam.

[0077] In other embodiments, the output end of the power mechanism 14 can be connected to the curtain shaft 4 for transmission. The power mechanism 14 drives the curtain shaft 4 to rotate, and the rotating curtain shaft 4 drives the winding wheel 5 to rotate synchronously. In this case, the power mechanism 14 can be installed on the left guide rail 11 or the right guide rail 11.

[0078] In other embodiments, the steering component can be a round shaft. The round shaft can be fixed to the frame 1 or rotatably mounted on the frame 1. Of course, the steering component can be omitted, and a steering groove can be provided on the frame 1. The other end of the first cable 6 passes through the guide groove, turns, and connects to the slider 8.

[0079] In other embodiments, the rotation center line of the steering component may have an angle with the plane on which the frame 1 is located, such as 30°, 60°, etc.

[0080] In other embodiments, the power mechanism 14 can be a hydraulic cylinder and a crank-connecting rod mechanism. The crank-connecting rod mechanism includes a crank, a connecting rod, and a moving block. One end of the connecting rod is connected to the moving block, and the other end is connected to one end of the crank. The other end of the crank is fixed on the rotating shaft of the winding wheel 5. When the hydraulic cylinder drives the moving block to move in the back-and-forth direction, the moving block drives one end of the crank to rotate around the other end through the connecting rod, thereby driving the winding wheel 5 to rotate.

[0081] In other embodiments, the number of guide auxiliary wheels 10 can be set according to the size of the skylight opening, for example, two, three, etc., and multiple guide auxiliary wheels 10 are arranged at intervals along the sliding direction parallel to the slider 8.

[0082] In other embodiments, the power mechanism 14 and the winding wheel 5 can be driven by a belt.

[0083] Additionally, referring to FIG7, one embodiment of this application provides a vehicle 1000, including the sunroof sunshade structure 100 of the above embodiment.

[0084] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
