[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] The embodiments of the present application provide a vehicle sunroof roller blind assembly and a vehicle, which can solve the problem in the related art that the middle cross beam of the top cover occupies a large amount of space in the passenger cabin, resulting in an abrupt shape and reduced visible space on the top of the passenger cabin.

[0044] See also Figure 3 As shown, the first aspect of the embodiment of the present application provides a vehicle sunroof roller blind assembly, comprising:

[0045] The top cover middle cross beam 20 is a sheet metal part formed by stamping a steel plate and extends along the width direction of the vehicle body for connecting the vehicle body side assembly 2. The top surface of the top cover middle cross beam 20 is recessed downward to form a covering space for accommodating the sunroof sunshade 10. The cross section of the top cover middle cross beam 20 is a "W" or "C" shaped structure with an open top. The X-axis direction in the embodiment of the present application is the length direction of the vehicle body, the Y-axis direction is the width direction of the vehicle body, and the Z-axis direction is the height direction of the vehicle body.

[0046] The sunroof sunshade 10 is located in the covering space of the middle cross beam 20 of the roof, and the sunroof sunshade 10 can rotate freely in the covering space of the middle cross beam 20 of the roof, so that the sunshade cloth 14 of the sunroof sunshade 10 can be extended from the covering space to cover the sunroof, and the sunshade cloth 14 of the sunroof sunshade 10 can be retracted into the covering space. The top of the middle cross beam 20 of the roof is bent to form an arc-shaped flange 21 extending along the width direction of the sunroof sunshade 10 and slidingly supporting the sunroof sunshade 10.

[0047] The part where the curved flange 21 of the cross beam 20 in the top cover fits with the sunshade cloth 14 of the sunroof sunshade 10 is the sliding part that supports the sunshade cloth 14 of the sunroof sunshade 10. Since the sunshade cloth 14 of the sunroof sunshade 10 is an appearance part and the curved flange 21 is a sheet metal part, the surface is usually rough. During the process of extending or rolling up the sunshade cloth 14, the sunshade cloth 14 and the curved flange 21 fit and rub all the way, which can easily scratch the sunshade cloth 14. To solve this problem, a black paint electrophoresis process is added to the surface of the curved flange 21 or a scratch-resistant rubber strip is applied to improve the surface quality of the sunshade cloth 14.

[0048] The top cover middle cross beam 20 of the vehicle sunroof roller blind assembly of the embodiment of the present application is not only used to connect the vehicle body side assembly 2 in the space enclosed by the sunroof, but also used as a sunshade bracket of the sunroof sunshade 10 to accommodate and slide support the sunroof sunshade 10. When the top cover middle cross beam 20 is connected to the vehicle body side assembly 2 in the space enclosed by the sunroof, it can not only meet the rigidity and strength design of the vehicle top cover, improve the bending, torsion and top pressure performance of the whole vehicle, but also can serve as a sunshade bracket of the sunroof sunshade 10 to accommodate and slide support the sunroof sunshade 10.

[0049] The embodiment of the present application cancels the sunshade bracket 1, and replaces the sunshade bracket 1 with the middle cross beam 20 of the top cover, and the middle cross beam 20 of the top cover accommodates and slidably supports the sunroof sunshade 10, thereby minimizing the X-axis and Z-axis dimensions of the middle cross beam 20 of the top cover and maximizing the visible area at the top of the passenger compartment. It can not only meet the arrangement of the sunroof sunshade 10, but also save a sunshade bracket 1, reduce the cost of parts, and increase the visible area in the middle of the sunroof.

[0050] In some alternative embodiments: See Figure 3As shown, the embodiment of the present application provides a vehicle sunroof roller blind assembly, wherein the sunroof sunshade curtain 10 of the vehicle sunroof roller blind assembly includes a first sunshade curtain 11 and a second sunshade curtain 12 arranged in parallel. The first sunshade curtain 11 and the second sunshade curtain 12 are parallel to each other and arranged at intervals, and the axes of the first sunshade curtain 11 and the second sunshade curtain 12 are parallel to the length direction of the cross beam 20 in the top cover. The first sunshade curtain 11 and the second sunshade curtain 12 both include a reel 13 and a sunshade curtain cloth 14 rolled up on the reel 13.

[0051] The free end of the sunshade curtain fabric 14 of the first sunshade curtain 11 extends toward the front of the middle cross beam 20 of the roof, and can be rolled up on the reel 13 of the first sunshade curtain 11 or moved forward relative to the reel 13 of the first sunshade curtain 11 to unfold. The free end of the sunshade curtain fabric 14 of the second sunshade curtain 12 extends toward the rear of the middle cross beam 20 of the roof, and can be rolled up on the reel 13 of the second sunshade curtain 12 or moved backward relative to the reel 13 of the second sunshade curtain 12 to unfold.

[0052] In the embodiment of the present application, a first sunshade curtain 11 and a second sunshade curtain 12 are arranged in the covering space of the middle cross beam 20 of the roof, and the sunshade curtain fabric 14 of the first sunshade curtain 11 is used to cover the front skylight located in front of the middle cross beam 20 of the roof after being unfolded toward the front of the vehicle body. The sunshade curtain fabric 14 of the second sunshade curtain 12 is used to cover the rear skylight located behind the middle cross beam 20 of the roof after being unfolded toward the rear of the vehicle body. The first sunshade curtain 11 and the second sunshade curtain 12 can be automatically unfolded sunshades or manually unfolded sunshades.

[0053] In some alternative embodiments: See Figure 3 As shown, an embodiment of the present application provides a vehicle sunroof roller blind assembly, the arc-shaped flange 21 of the vehicle sunroof roller blind assembly includes a front arc-shaped flange 22 located at the front end of the middle cross beam 20 of the top cover for slidingly supporting the sunshade fabric 14 of the first sunshade curtain 11 to extend or retract, and a rear arc-shaped flange 23 located at the rear end of the middle cross beam 20 of the top cover for slidingly supporting the sunshade fabric 14 of the second sunshade curtain 12 to extend or retract.

[0054] The front arc flange 22, the rear arc flange 23 and the top cover middle cross beam 20 of the embodiment of the present application are formed by stamping and bending steel plate materials. The front arc flange 22 and the rear arc flange 23 provide support for the sunshade fabric 14 of the first sunshade curtain 11 and the second sunshade curtain 12 to extend or roll up, so that the height of the sunshade fabric 14 of the first sunshade curtain 11 and the second sunshade curtain 12 is higher than the ceiling interior panel in the vehicle.

[0055] In some alternative embodiments: See Figures 4 to 7As shown, the embodiment of the present application provides a vehicle sunroof roller blind assembly, the top cover middle cross beam of the vehicle sunroof roller blind assembly includes a top cover middle cross beam body 24, and end connecting plates 25 connected to the left and right ends of the top cover middle cross beam body 24 by bolts 31, and the top cover middle cross beam body 24 and the end connecting plates 25 are designed in a split type, so that the sunroof roller blind assembly can be installed on the vehicle body side assembly 2. The top cover middle cross beam body 24 is connected to the vehicle body side assembly 2 through the end connecting plates 25.

[0056] In some alternative embodiments: See Figure 4 , Figure 5 , Fig.12 and Fig.13 As shown, an embodiment of the present application provides a vehicle sunroof roller blind assembly, in which first mounting holes 26 for connecting end connecting plates 25 are provided at both left and right ends of a middle cross beam body 24 of a top cover, and two first mounting holes 26 are respectively provided at the left and right ends of the middle cross beam body 24 of the top cover, and both are located at the bottom position of the middle cross beam body 24 of the top cover.

[0057] A second mounting hole 27 adapted to the first mounting hole 26 for connecting to the top cover middle cross beam body 24 is formed at one end of the end connecting plate 25, and a third mounting hole 28 bolted to the body side assembly 2 is formed at the other end of the end connecting plate 25. The second mounting hole 27 is an oblong hole extending along the width direction of the body.

[0058] The vehicle sunroof roller blind assembly also includes sunshade guide rails 30 located at the left and right ends of the top cover middle cross beam body 24 and fixedly connected to the top cover middle cross beam body 24 by bolts 31, and the sunshade guide rails 30 are located above the top cover middle cross beam body 24. The reel 13 of the sunroof sunshade 10 is rotatably connected to the sunshade guide rails 30. The end connecting plate 25 and the top cover middle cross beam body 24 are sub-components of the top cover middle cross beam 20, and are connected to the sunshade guide rails 30 by bolts 31 respectively.

[0059] The end connecting plate 25, the top cover middle cross beam body 24 and the sunshade guide rail 30 are arranged in order from bottom to top in the height direction of the vehicle body. The end connecting plate 25, the top cover middle cross beam body 24 and the sunshade guide rail 30 are connected and fastened together by bolts 31. After the end connecting plate 25 is inserted into the bolts 31 through the third mounting hole 28 and connected to the vehicle body side assembly 2, the top cover middle cross beam body 24 and the sunshade guide rail 30 are fixed to the vehicle body side assembly 2.

[0060] In some alternative embodiments: See Figures 4 to 7As shown, an embodiment of the present application provides a vehicle sunroof roller blind assembly, wherein the tops of the left and right ends of the top cover middle cross beam body 24 of the vehicle sunroof roller blind assembly are provided with rubber-coated support blocks 40 for elastically supporting the sunshade guide rail 30, and the rubber-coated support blocks 40 are located between the sunshade guide rail 30 and the top cover middle cross beam body 24 and are located in the covering space of the top cover middle cross beam 20.

[0061] The end connecting plate 25, the top cover middle cross beam body 24, the rubber-coated support block 40 and the sunshade guide rail 30 are connected by bolts 31. The end connecting plate 25, the top cover middle cross beam body 24, the rubber-coated support block 40 and the sunshade guide rail 30 are arranged in sequence from bottom to top in the height direction of the vehicle body. The rubber-coated support block 40 includes a metal frame, a plastic cladding coated on the outer wall of the metal frame, and a rubber outer layer coated on the outer wall of the plastic cladding.

[0062] Since the sunshade guide rail 30 has a very high installation accuracy requirement, and the end connecting plate 25, the top cover middle cross beam body 24 and the sunshade guide rail 30 are arranged in sequence from bottom to top in the height direction of the vehicle body and are connected to each other through bolts 31, the dimensional processing accuracy of the parts is high, and the accuracy of the parts is difficult to control, resulting in a very high risk of deformation of the sunshade guide rail 30 after assembly. Therefore, a rubber-coated support block 40 that elastically supports the sunshade guide rail 30 is provided at the top of the left and right ends of the top cover middle cross beam body 24. The rubber-coated support block 40 itself has elastic deformation and rigid support capabilities, and can absorb the tolerance of dimensional fluctuations in the Y and Z directions.

[0063] The rubber-coated support block 40 of the embodiment of the present application comprises a metal frame, a plastic coating wrapped around the outer wall of the metal frame, and a rubber outer layer wrapped around the outer wall of the plastic coating. During assembly, the rubber outer layer surrounding the rubber-coated support block 40 is squeezed to absorb the tolerances brought by various components.

[0064] The metal frame of the rubber-coated support block 40 is used to improve the overall rigidity of the rubber-coated support block 40, the plastic cladding coated on the outer wall of the metal frame is used to reduce the weight of the rubber-coated support block 40 and control the outer dimensions of the outer wall, and the rubber outer layer is coated on the outer wall of the plastic cladding to reduce the surface hardness of the rubber-coated support block 40, so that the rubber-coated support block 40 has elastic deformation capability.

[0065] The rubber-coated support block 40 is located at a joint where the force is concentrated, which is particularly important for the stiffness, strength, top pressure and other performances of the whole vehicle. In order to improve the performance, a metal skeleton is embedded in the rubber-coated support block 40 as a sheet metal part (the sheet metal thickness range is 0.6mm-2.5mm, selected according to performance requirements). The material of the plastic cladding is usually PA6, PC+ABS, PP+GF30, PP+EPDM-TD20, etc., which is selected according to the requirements.

[0066] In some alternative embodiments: See Figures 8 to 11 As shown, an embodiment of the present application provides a vehicle sunroof roller blind assembly, wherein the rubber-coated support block 40 of the vehicle sunroof roller blind assembly includes a vertically arranged side support block 42 and a laterally arranged bottom support block 41, and the side support block 42 and the bottom support block 41 are interconnected to form an "L"-shaped structure.

[0067] The bottom surface of the bottom support block 41 is provided with a lower elastic support column 44 that contacts the middle cross beam body 24 of the top cover, and the top surface of the bottom support block 41 is provided with an upper elastic support column 45 that contacts the sunshade guide rail 30. A side of the side support block 42 close to the sunshade guide rail 30 is provided with a plurality of elastic protrusions 43 arranged at intervals, and the elastic protrusions 43 contact the sunshade guide rail 30. The side support block 42 is fixedly connected to the sunshade guide rail 30 by bolts 31.

[0068] The side support block 42 of the embodiment of the present application is fitted with the sunshade guide rail 30 in the Y direction, and is usually designed to fit the entire large surface, but the overlapping structure in this area is complex, which will cause difficulties in dimensional accuracy matching and easy friction noise. To solve this problem, a plurality of elastic protrusions 43 are arranged at intervals on the side of the side support block 42 close to the sunshade guide rail 30. The elastic protrusions 43 are long strips, and the width of the elastic protrusions 43 is usually 1mm to 3mm. The elastic protrusions 43 protrude from the surface of the side support block 42 by 0.5mm.

[0069] In the embodiment of the present application, a lower elastic support column 44 in contact with the middle cross beam body 24 of the top cover is provided on the bottom surface of the bottom support block 41, and an upper elastic support column 45 in contact with the sunshade guide rail 30 is provided on the top surface of the bottom support block 41. The lower elastic support column 44 and the upper elastic support column 45 are both made of rubber elastic material. The bottom support block 41 is respectively fitted with the sunshade guide rail 30 and the middle cross beam body 24 of the top cover in the Z direction, and the performance is usually improved by designing a full fit. However, the overlap structure in this area is complex, and there is a problem of difficulty in matching dimensional accuracy. In order to solve this problem, a partial fit is adopted in the bolt 31 connection area through the lower elastic support column 44 and the upper elastic support column 45.

[0070] The bottom support block 41 is partially fitted with the sunshade guide rail 30 and the top cover middle cross beam body 24 in the Z direction using the lower elastic support column 44 and the upper elastic support column 45. Two lower elastic support columns 44 and two upper elastic support columns 45 are symmetrically provided on the bottom support block 41. The lower elastic support column 44 is a rectangular structure, and the upper elastic support column 45 is a circular structure. The lower elastic support column 44 bears more weight than the upper elastic support column 45, so the cross section of the lower elastic support column 44 is larger than the cross section of the upper elastic support column 45.

[0071] In some alternative embodiments: See Figures 5 to 11As shown, the embodiment of the present application provides a vehicle sunroof roller blind assembly, the top surface of the bottom support block 41 of the vehicle sunroof roller blind assembly is provided with a positioning pin 47 connected to the sunshade guide rail 30, the positioning pin 47 is used to pre-position the sunshade guide rail 30 before installing the sunshade guide rail 30 on the rubber-coated support block 40, so as to facilitate the subsequent precise fixing of the sunshade guide rail 30 on the top of the rubber-coated support block 40. A fourth mounting hole 46 is provided on the bottom support block 41, which passes through the lower elastic support column 44 and the upper elastic support column 45.

[0072] When the end connecting plate 25, the middle cross beam body 24 of the top cover, the rubber-coated support block 40 and the sunshade guide rail 30 are connected in sequence from bottom to top in the height direction of the vehicle body, the bolts 31 are sequentially inserted into the second mounting hole 27 of the end connecting plate 25, the first mounting hole 26 of the middle cross beam body 24 of the top cover, the fourth mounting hole 46 of the rubber-coated support block 40, and then inserted into the sunshade guide rail 30 and tighten the nuts.

[0073] The top of the left and right ends of the middle cross beam body 24 of the top cover and the top of the end connecting plate 25 are provided with fifth mounting holes 29 for directly connecting the sunshade guide rail 30 through bolts 31. When the end connecting plate 25, the middle cross beam body 24 of the top cover and the sunshade guide rail 30 are connected in sequence from bottom to top in the height direction of the vehicle body, the bolts 31 are sequentially inserted into the fifth mounting holes 29 of the end connecting plate 25 and the fifth mounting holes 29 of the middle cross beam body 24 of the top cover, and then inserted into the sunshade guide rail 30 and tightened with nuts.

[0074] The second mounting hole 27 of the end connecting plate 25 is designed to be an oblong hole extending along the Y direction. The second mounting hole 27 mainly absorbs the dimensional tolerance caused by the manufacturing and assembly process of the body side assembly 2 and the top cover assembly. The opening size of the second mounting hole 27 is designed to be an oblong hole of 10*20mm, with a tolerance of (0mm~+0.2mm).
