[0002] Electric sunshades are increasingly being used in conjunction with panoramic sunroofs in automobiles to provide heat insulation and other benefits. Current technology typically involves attaching the sunshade fabric to a roller, with a motor driving the roller to roll up the fabric. However, with the evolution of automotive designs, the roofline now features a streamlined, curved shape. This increases the gap between the flat surface of the sunshade fabric and the curved roofline, resulting in wasted space in the vertical direction of the vehicle's interior. Utility Model Content

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium.

[0043] Considering the evolution of automotive styling, the roof of a vehicle now features a streamlined design with a certain degree of curvature. This increases the gap between the flat surface of the curtain and the curved roof, resulting in wasted space in the vertical direction of the vehicle interior. This application provides a roller assembly, a sunshade assembly, and a glass assembly that can adapt to the streamlined design of the roof with a certain degree of curvature, reducing the gap between the flat surface of the curtain and the curved roof, improving the utilization rate of space in the vertical direction of the vehicle interior, and facilitating application and promotion.

[0044] For details, please refer to Figure 1 and Figure 2 One embodiment of this application provides a sunshade assembly 1. It may include a roller assembly 10 and a fixing base 21, with the end of the roller assembly 10 connected to the fixing base 21. Additionally, the sunshade assembly 1 may also include a sunshade component 20, which may include a curtain fabric 22, a pull rod 23, and a guide rail assembly 24. The curtain fabric 22 is wound around the roller assembly 10 and has an exit end. The pull rod 23 is connected to the exit end and is slidably mounted on the guide rail assembly 24.

[0045] According to another aspect of this application, a glass assembly is also provided, which may include the aforementioned sunshade assembly 1. Depending on actual needs, the glass assembly may be, but is not limited to, any one of a sunroof glass assembly, a vehicle window glass assembly, or a corner window glass assembly. For example, in this application, the glass assembly is specifically a sunroof glass assembly. Specifically, the glass assembly may include a sunroof, and the sunshade assembly 1 may be installed on the sunroof to provide heat insulation and sun shading effects. Furthermore, the aforementioned sunroof may, but is not limited to, be implemented as a sunroof with a curved design.

[0046] This application makes the following improvements to the above-mentioned reel assembly 10.

[0047] Continue reading Figure 3 , Figure 4 , Figure 5 and Figure 6One embodiment of this application provides a reel assembly 10 that may include a reel assembly 100 and an outer tube assembly 200. The end of the reel assembly 100 is connected to a fixing base 21, and the fabric 22 is wound around the outer tube assembly 200. The reel assembly 100 is arc-shaped along its axial direction. Figure 7 As shown, the outer tube assembly 200 includes at least two connecting tubes 210 that are spliced ​​together and movably sleeved on the reel assembly 100. The ends of the connecting tubes 210 are provided with movable portions 210a. Two adjacent connecting tubes 210 are movably connected through the movable portions 210a, so that the axial included angle of the two adjacent connecting tubes 210 is set at a variable angle, and the outer tube assembly 200 can rotate about the axial direction of the reel assembly 100.

[0048] Understandably, the curtain 22 described above in this application can be wound around the connecting pipe 210 of the outer tube assembly 200.

[0049] It should be noted that, Figure 7 The diagram shows the state in which the snap-fit ​​part a1 and the snap-fit ​​slot are snapped together. Therefore, only the identifier of the snap-fit ​​part a1 is shown in the figure, and the identifier of the snap-fit ​​slot is not shown.

[0050] The aforementioned roller assembly 10 is movably connected to two adjacent connecting pipes 210 via a movable part 210a, allowing the axial included angle of the two adjacent connecting pipes 210 to be set at a variable angle. This allows the outer tube assembly 200 to have a certain curvature design. Thus, when the curtain 22 is installed on the outer tube assembly 200, the curtain 22 can also have a corresponding curvature design, thereby adapting to the streamlined design of the vehicle roof with a certain curvature, reducing the gap between the plane of the curtain 22 and the curvature design of the vehicle roof, improving the space utilization rate in the height direction of the vehicle interior, and facilitating application and promotion.

[0051] Optionally, the movable part 210a may include a snap-fit ​​part a1 and a snap-fit ​​groove along the circumference of the connecting pipe 210. Two adjacent connecting pipes 210 are movably snapped together by the snap-fit ​​part a1 of one and the snap-fit ​​groove of the other. This allows the axial included angle of the two adjacent connecting pipes 210 to be set in a variable angle, and the structure is simple and reliable.

[0052] Optionally, the movable part 210a includes at least two snap-fit ​​parts a1 and at least two snap-fit ​​slots. The snap-fit ​​parts a1 and the snap-fit ​​slots are alternately arranged along the circumference of the connecting tube 210, and each snap-fit ​​part a1 and each snap-fit ​​slot is interconnected in a cyclic wave pattern. This helps to reduce the resistance to movement and improve the smoothness of the movement between the snap-fit ​​parts a1 and the snap-fit ​​slots. In addition, by adjusting the number of connecting tubes 210, the adaptability of the reel assembly 10 in different specification scenarios is improved.

[0053] It is worth noting that, upon rereading Figure 1 and Figure 2The curtain fabric 22 of the sunshade assembly 1 can be pasted and rolled up onto the outer tube assembly 200. In the rolled-up state, the curtain fabric 22 can have the same curvature design as the outer tube assembly 200. In the flattened state, the curtain fabric 22 can also have a corresponding curved plane under the restraint of the outer tube assembly 200, thereby reducing the droop of the curtain fabric 22 and reducing the gap between the plane of the curtain fabric 22 and the curved design of the car roof. This allows the curtain fabric 22 to fit the car roof better, improves the space utilization in the height direction of the car, and also helps to reduce the friction of the curtain fabric 22 during movement, thereby reducing the wrinkles of the curtain fabric 22 and the motor noise, making it easy to apply and promote.

[0054] More notably, the interlocking design of the snap-fit ​​part a1 and the snap-fit ​​groove allows the outer tube assembly 200 to adapt to the curvature of the support rod 110 during rotation by the real-time interaction between the snap-fit ​​part a1 and the snap-fit ​​groove. This ensures that the outer tube assembly 200 can rotate while maintaining a certain curvature, thereby guaranteeing the reliability of the fabric 22's function of feeding and retracting fabric as the outer tube assembly 200 rotates.

[0055] Of course, in other embodiments, the movable part 210a may also be implemented as a malleable sleeve or spring structure, etc. The malleable sleeve or spring structure is connected to the connecting pipe 210 by welding or snap-fitting, etc., so as to realize the design of the movable part 210a being deformable in real time, ensuring that the outer tube assembly 200 can rotate while maintaining a certain curvature.

[0056] Optionally, please refer to Figure 5 The reel assembly 100 may include a support rod 110 and an elastic component 120. The support rod 110 is arc-shaped and has a hollow cavity 110a. The elastic component 120 has a first end 120a and a second end 120b. The elastic component 120 passes through the hollow cavity 110a, and its second end 120b is fixedly connected to the support rod 110. Figure 3 , Figure 5 and Figure 8 As shown, the outer tube assembly 200 is sleeved on the support rod 110 and connected to the first end 120a, so that when the outer tube assembly 200 rotates axially around the roller assembly 100, the elastic component 120 can be twisted under the drive of the outer tube assembly 200. Specifically, the elastic component 120 is used to store energy by being twisted relative to the support rod 110 under the drive of the outer tube assembly 200 when the curtain 22 is rolled up, and further releases energy when the curtain 22 is unrolled to improve the smoothness of the unrolling of the curtain 22.

[0057] Optionally, continue reading Figure 7An adjustment gap d is provided between the movable portions 210a of two adjacent connecting pipes 210. The value range of the adjustment gap d is configured as follows: when the two adjacent connecting pipes 210 are coaxially arranged, the adjustment gap d is 0.05mm-0.5mm, such as 0.05mm, 0.08mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, or 0.5mm. This helps to set the adjustable margin of the two adjacent connecting pipes 210 within a reasonable range. It is worth noting that if the adjustment gap d is too large, there will be abnormal noise during the operation of the roller assembly 10. Therefore, setting the adjustment gap d to 0.05mm-0.5mm not only ensures sufficient adjustable margin between the two adjacent connecting pipes 210, but also helps to reduce abnormal noise and lower the noise level.

[0058] Preferably, the range of the aforementioned adjustment gap d is configured such that when two adjacent snap rings are coaxially arranged, the adjustment gap d is 0.05mm-0.25mm, such as 0.05mm, 0.08mm, 0.1mm, 0.15mm, 0.2mm or 0.25mm, etc.

[0059] Optionally, the movable portions 210a of two adjacent connecting pipes 210 can be formed by secondary processing on the straight pipe using processes such as laser cutting or high-pressure water cutting. Furthermore, the number of segments, cutting shape, and cutting gap of the connecting pipe 210 are standardized designs with adjustable allowances as needed. Understandably, the aforementioned adjustable gap d can be formed during the cutting process.

[0060] Optionally, continue reading Figure 5 The elastic component 120 has a first connecting end 122 at its first end 120a and a second connecting end 123 at its second end 120b. The elastic component 120 also includes an elastic body 121. The first connecting end 122 and the second connecting end 123 are respectively connected to the two ends of the elastic body 121. The first connecting end 122 movably abuts against the end of the support rod 110, and the second connecting end 123 is fixedly connected to the support rod 110. Thus, when the first connecting end 122 is driven to rotate relative to the support rod 110, the elastic body 121 can be twisted to store energy because the second connecting end 123 is fixedly connected to the support rod 110. The structure is simple and reliable.

[0061] Optionally, the elastomer 121 may, but is not limited to, be implemented as a torsion spring.

[0062] It is worth noting that the first connecting end 122 of the elastic component 120 can be used as the first end 120a of the aforementioned elastic component 120. The first end 120a of the aforementioned elastic component 120 is connected to the end of the outer tube assembly 200 near the first end 120a. This can be implemented as the first connecting end 122 being connected to the end of the outer tube assembly 200 near the first end 120a. This enables the outer tube assembly 200 and the elastic body 121 to rotate synchronously, realizing the torsional energy storage of the elastic body 121 while the curtain 22 is rolled up and down. The structure is durable and reliable.

[0063] It is also worth noting that the second connecting end 123 of the elastic component 120 can be used as the second end 120b of the aforementioned elastic component 120. The second end 120b of the aforementioned elastic component 120 and the support rod 110 are fixedly installed together. This can be implemented as the second connecting end 123 being fixedly installed with the support rod 110, thus improving the ease of installation of the elastic component 120 and the support rod 110.

[0064] Optionally, combined Figure 5 As shown, the second connecting end 123 may be provided with a first limiting hole 1231, and the support rod 110 may be provided with a second limiting hole 110b. The first limiting hole 1231 and the second limiting hole 110b are aligned with each other and fixed by a pin, thus realizing the mutual fixed installation between the elastic component 120 and the support rod 110, improving the ease of installation.

[0065] Optionally, both the first connecting end 122 and the second connecting end 123 may be provided with spiral grooves. The spiral grooves are used to engage the ends of the elastic body 121, thereby improving the ease and stability of engaging and fixing the two ends of the elastic body 121 with the first connecting end 122 and the second connecting end 123 respectively.

[0066] Optionally, see Figure 3 and Figure 8 The connecting pipe 210 of the outer pipe assembly 200 near the first end 120a is the first pipe 211. (Combined) Figure 8 and Figure 9 As shown, the outer tube assembly 200 may include a third connecting end 220, and the first connecting end 122 is connected to the end of the first tube 211 through the third connecting end 220. This helps to connect the outer tube assembly 200 with the elastic component 120 and realize torque transmission. The installation process is simple and reliable.

[0067] Optionally, continue reading Figure 8 and Figure 9The first tube 211 is provided with a first limiting groove 211a at the end away from its movable part 210a. The third connecting end 220 is provided with a first limiting part 220a along its circumference. The first limiting part 220a is engaged with the first limiting groove 211a. In this way, the third connecting end 220 and the first tube 211 are limited in the circumference. The structure is simple and reliable.

[0068] Optionally, please continue reading Figure 8 and Figure 9 As shown, both the first connecting end 122 and the third connecting end 220 are provided with a second limiting part 220b and a second limiting groove along the circumferential direction. The first connecting end 122 passes through the third connecting end 220, and the second limiting part 220b and the second limiting groove are locked together. This achieves the circumferential limiting of the first connecting end 122 and the third connecting end 220, thereby realizing the connection between the outer tube assembly 200 and the elastic assembly 120 and realizing the torque transmission. The structure is simple and reliable, and the ease of installation is improved.

[0069] It should be noted that, Figure 8 The diagram shows the state in which the second limiting part 220b and the second limiting groove are engaged with each other. Therefore, only the identifier of the second limiting part 220b is shown in the figure, and the identifier of the second limiting groove is not shown. Understandably, the second limiting part 220b and the second limiting groove are alternately arranged in the circumferential direction.

[0070] Optionally, please continue reading Figure 9 The first tube 211 has a first locking hole 211b at one end away from its movable part 210a, and the third connecting end 220 has a first locking claw 220c at one end. A portion of the third connecting end 220 passes through the first tube 211 and the first locking claw 220c engages with the first locking hole 211b. This enables quick assembly and disassembly of the third connecting end 220 and the first tube 211, improving the ease of assembly and disassembly.

[0071] Of course, in some other embodiments, the limiting of the third connecting end 220 and the first tube 211, and the limiting of the first connecting end 122 and the third connecting end 220, can be achieved by means of, but not limited to, opening pins or welding, which will not be elaborated here.

[0072] Optionally, combined Figure 5 , Figure 6 , Figure 10 and Figure 11 As shown, the connecting pipe 210 near the second end 120b of the outer tube assembly 200 is the second pipe 212. The outer tube assembly 200 includes an end cap 230, which is connected to the end of the second pipe 212. The end cap 230 is used to fit onto the roller assembly 100, which helps to improve the smoothness of the rotation of the outer tube assembly 200 relative to the support rod 110 and helps to reduce rotation noise.

[0073] Optionally, combined Figure 10 As shown, the second tube 212 has a second locking hole 212a at one end away from its movable part 210a, and the end cap 230 has a second locking claw 230a at one end. The end cap 230 is partially inserted through the first tube 211, so that the second locking claw 230a engages with the second locking hole 212a. This enables quick assembly and disassembly of the end cap 230 and the second tube 212, improving the ease of assembly and disassembly.

[0074] Optionally, please continue reading Figure 10 The second tube 212 is provided with a third limiting groove 212b at the end away from its movable part 210a. The end cap 230 is provided with a third limiting part 230b along its circumference. The third limiting part 230b is engaged with the third limiting groove 212b. This helps to improve the circumferential limiting effect of the outer tube assembly 200 and the end cap 230, and improves the rotational stability of the outer tube assembly 200.

[0075] Optionally, combined Figure 3 , Figure 5 and Figure 11 As shown, the reel assembly 100 may include a support base 130, which is engaged with the end of the support rod 110 near the second end 120b. The support base 130 is also fixedly connected to the fixed base 21, thereby fixing the support rod 110 relative to the fixed base 21. This enables both the outer tube assembly 200 and the elastic assembly 120 to rotate relative to the support rod 110, resulting in a simple and reliable structure.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
