Abstract
Description
Technical Field
[0001] This application relates to the field of vehicles, and more particularly to a base, a two-way sunshade, and a vehicle window. Background Technology
[0002] The sunshades installed on vehicle windows primarily serve to insulate against heat, block ultraviolet rays, and protect the privacy of passengers inside the vehicle. Vehicle windows with glass guide rails include both lift-up and fixed glass. Because separate curtains are required for the lift-up and fixed glass, existing sunshades cannot simultaneously cover both types of glass. Furthermore, the existing sunshade bases cover a large area of the glass, affecting its normal use. Summary of the Invention
[0003] This application provides a base, a two-way sunshade, and a vehicle window. The curtain of the two-way sunshade can extend along both sides of the base to block light from the glass on both sides of the base. After the curtain of the two-way sunshade is rolled up, the area of the base that blocks the glass is relatively small.
[0004] In a first aspect, this application provides a base having a receiving space extending along a third direction. The receiving space has a first installation space and a second installation space, which are arranged side by side in a second direction. The base is provided with a first outlet corresponding to the first installation space and a second outlet corresponding to the second installation space. The orientation of the first outlet and the orientation of the second outlet are opposite in a first direction. The first direction X, the second direction Y, and the third direction Z intersect each other.
[0005] In some embodiments, the base includes a partition and two end plates, with one end plate connected to each end of the partition in the third direction, and the receiving space formed between the two end plates. The first mounting space and the second mounting space are located on both sides of the partition along the second direction.
[0006] In some embodiments, the partition includes a stepped first plate, a connecting plate, and a second plate, wherein the connecting plate is connected to the first plate and the second plate on opposite sides in the second direction, respectively.
[0007] In some embodiments, the base further includes a first cover and a second cover, the first cover and the second cover being distributed on both sides of the partition along the second direction;
[0008] The first cover is connected to the second plate and the first cover covers the side of the first installation space away from the partition.
[0009] The second cover is connected to the first plate and covers the second installation space on the side away from the partition.
[0010] In some embodiments, a first compensation plate is connected to the end of the first plate away from the second plate, and the first outlet is formed between the first cover and the first compensation plate;
[0011] The second outlet is formed between the second cover and the second plate.
[0012] Secondly, this application provides a two-way sunshade curtain, including the base described in the first aspect and a first roller blind assembly and a second roller blind assembly disposed on the base, wherein the first roller blind assembly is disposed in the first installation space and the second roller blind assembly is disposed in the second installation space.
[0013] The extension direction of the curtain of the first roller blind assembly is opposite to that of the extension direction of the curtain of the second roller blind assembly in a first direction. The first direction, the second direction, and the third direction intersect each other. The edge of the extension end of the curtain of the first roller blind assembly is inclined relative to the axis of the first roller blind assembly.
[0014] In some embodiments, the curtain of the first roller blind assembly extends from the side of the first roller blind assembly closer to the second roller blind assembly.
[0015] In some embodiments, the curtain of the second roller blind assembly extends from the side of the second roller blind assembly closer to the first roller blind assembly.
[0016] In some embodiments, the first roller blind assembly includes a fixed shaft, bushings, a return member, and the curtain fabric. Both ends of the fixed shaft are connected to the base. Two bushings are sleeved around the fixed shaft. The two bushings are located at both ends of the fixed shaft. Both bushings are connected to one end of the curtain fabric. At least one bushing is provided with the return member between it and the fixed shaft.
[0017] Thirdly, this application provides a vehicle window, which includes the two-way sunshade described in the second aspect.
[0018] The bidirectional sunshade, window, and vehicle provided in this application embodiment include a base with a receiving space extending in a third direction, allowing a first and a second roller blind assembly to be installed within the receiving space. By arranging the first mounting space for the first roller blind assembly and the second mounting space for the second roller blind assembly side-by-side in a second direction, the area of the base obstructing the window glass is minimized. By setting the first outlet of the first mounting space and the second outlet of the second mounting space opposite in a first direction, the curtains of the first roller blind assembly located in the first mounting space and the second roller blind assembly located in the second mounting space extend along opposite sides of the base in a first direction to cover the entire window glass. By tilting the edge of the extended end of the curtain of the first roller blind assembly relative to the axis of the first roller blind assembly, the extended curtain of the first roller blind assembly can completely cover the lifting glass.
[0019] The first and second roller blind assemblies respectively cover the lift-up glass and the fixed glass. After the curtains of the first and second roller blind assemblies are rolled up, the area of the base covering the window glass is relatively small. Attached Figure Description

[0036] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0037] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.
[0038] like Figures 1 to 7 As shown, this application embodiment provides a two-way sunshade curtain, including a base 1 and a first roller blind assembly 2 and a second roller blind assembly 3 disposed on the base 1. The extension direction of the curtain fabric 8 of the first roller blind assembly 2 is opposite to the extension direction of the curtain fabric 8 of the second roller blind assembly 3 in a first direction X. The first roller blind assembly 2 and the second roller blind assembly 3 are distributed along a second direction Y, and the first direction X and the second direction Y intersect. The edge of the extended end of the curtain fabric 8 of the first roller blind assembly 2 is inclined relative to the axis of the first roller blind assembly 2. The first direction X, the second direction Y, and the third direction Z intersect each other.
[0039] The two-way sunshade provided in this embodiment can be installed on the glass guide rail 6 of a vehicle window. In specific application, the base 1 is installed on the glass guide rail 6. The first direction X is the length direction of the vehicle, that is, the length direction of the window. The vehicle window with the glass guide rail 6 includes a liftable glass and a fixed glass, which are located on both sides of the glass guide rail 6 in the first direction X. The extension direction of the curtain 8 of the first roller blind assembly 2 is opposite to the extension direction of the curtain 8 of the second roller blind assembly 3 in the first direction X, so that when the curtain 8 of the first roller blind assembly 2 and the curtain 8 of the second roller blind assembly 3 are extended, they respectively serve to block the light from the liftable glass and the fixed glass on both sides of the glass guide rail 6.
[0040] For example, the second direction Y intersects the first direction X perpendicularly, that is, the second direction Y is the thickness direction of the window glass 9.
[0041] The first roller blind assembly 2 and the second roller blind assembly 3 are distributed along the second direction Y, so that the projection of the base 1 used to accommodate the first roller blind assembly 2 and the second roller blind assembly 3 onto the window glass 9 along the second direction Y is small. When the curtain 8 of the first roller blind assembly 2 and the curtain 8 of the second roller blind assembly 3 are rolled up, the two-way sunshade covers the window glass 9 as little as possible and does not affect the normal use of the window glass 9.
[0042] Because the glass guide rail 6 is inclined relative to the height of the car window glass 9, such as Figure 1 and Figure 4 As shown, the glass guide rail 6 extends along the third direction Z. In order to ensure that the curtain 8 of the first roller blind assembly 2 can extend smoothly relative to the window glass 9 and maintain flatness after being pulled out, the axial direction of the fixed shaft 21 of the first roller blind assembly 2 is at a preset angle with the third direction Z. When the tilt angle of the window glass 9 is ignored, the axial direction of the fixed shaft 21 of the first roller blind assembly 2 is close to the vertical direction.
[0043] like Figure 1 and Figure 4 As shown, the mating edge between the window glass and the window frame is an inclined edge. The edge of the protruding end of the curtain 8 of the first roller blind assembly 2 is inclined relative to the axis of the first roller blind assembly 2 to match the window frame, so that when the curtain 8 of the first roller blind assembly 2 extends to cover the window glass, it can completely cover the window glass. Similarly, the edge of the curtain 8 of the second roller blind assembly 3 is inclined relative to the axis of the second roller blind assembly 3. The axis of the first roller blind assembly 2 is the axis of the roller 5 of the first roller blind assembly 2.
[0044] This application provides a base 1, such as... Figure 2 , Figure 4 and Figure 5As shown, the base 1 has a receiving space extending along the third direction Z. The receiving space has a first mounting space 4 and a second mounting space 5. The first mounting space 4 and the second mounting space 5 are arranged side by side in the second direction. The base 1 is provided with a first outlet 16 corresponding to the first mounting space 4 and a second outlet 17 corresponding to the second mounting space 5. The orientation of the first outlet 16 and the orientation of the second outlet 17 are opposite in the first direction.
[0045] The base 1 has a receiving space extending along the third direction Z, which allows the first roller blind assembly 2 and the second roller blind assembly 3 to be installed in the receiving space. By arranging the first mounting space 4 for mounting the first roller blind assembly 2 and the second mounting space 5 for mounting the second roller blind assembly 3 side by side in the second direction Y, the area of the base 1 that obstructs the vehicle window glass is minimized.
[0046] In some embodiments, the base 1 includes a partition 10 for connection with the glass guide rail 6. A first mounting space 4 and a second mounting space 5 are located on opposite sides of the partition 10 along a second direction Y. A first roller blind assembly 2 is disposed within the first mounting space 4, and a second roller blind assembly 3 is disposed within the second mounting space 5.
[0047] In a specific implementation, the partition 10 has an end plate 19 connected to each end of its third direction Z. The rollers of the first roller blind assembly 2 and the second roller blind assembly 3 are connected between the two end plates 19. Alternatively, the two end plates 19 can be omitted, and two support parts can be formed by extending from both ends of the partition 10 along the second direction Y. The rollers of the first roller blind assembly 2 and the second roller blind assembly 3 are connected between the two support parts. Or, the support parts can be formed on other components of the base 1.
[0048] The partition 10 supports the first roller blind assembly 2 and the second roller blind assembly 3 via two end plates 19 or two support parts. The first roller blind assembly 2 and the second roller blind assembly 3 are located on opposite sides of the partition 10 in the second direction Y, and both the first direction X and the second direction Y intersect with the third direction Z. In practice, the partition 10 and the glass guide rail 6 can be connected by bolts, with multiple bolts spaced apart along the third direction Z.
[0049] By setting end plates 19 at both ends of the partition 10 along the third direction Z, the first roller blind assembly 2 and the second roller blind assembly 3 are connected between the two end plates 19. By setting the first roller blind assembly 2 and the second roller blind assembly 3 to be located on both sides of the partition 10 in the second direction Y, the area of the base 1 obstructing the window glass after the curtain 8 of the first roller blind assembly 2 and the curtain 8 of the second roller blind assembly 3 are minimized.
[0050] The first roller blind assembly 2 includes a fixed shaft 21, bushings 22, a return element, and curtain fabric 8. Both ends of the fixed shaft 21 are connected to the base 1. Two bushings 22 are fitted around the fixed shaft 21, located at both ends of the fixed shaft 21 and connected to one end of the curtain fabric 8. At least one bushing 22 has a return element between it and the fixed shaft 21, allowing the curtain fabric 8 to return to its original position when rolled up. The return element can be a spring or similar material with deformation capabilities, giving the bushing 22 a tendency to return to its initial position, thus keeping the curtain fabric 8 taut or allowing it to be rolled up to the fixed shaft 21. The structure of the second roller blind assembly 3 is the same as that of the first roller blind assembly 2, and will not be described further here.
[0051] In specific implementation, such as Figures 5 to 7 As shown, the two end plates 19 are respectively connected to both ends of the fixed shaft 21. Furthermore, one end of the fixed shaft 21 is connected to the end plate 19 by a fastener 23, and the other end of the fixed shaft 21 is inserted into the slot 100 of the end plate 19 and engaged with the base 1.
[0052] like Figure 1 and Figure 2 As shown, the curtain 8 of the first roller blind assembly 2 serves as a light-blocking element for the lift-up glass, while the curtain 8 of the second roller blind assembly 3 serves as a light-blocking element for the fixed glass. The area of the lift-up glass is larger than that of the fixed glass, therefore the length of the curtain 8 of the first roller blind assembly 2 is greater than the length of the curtain 8 of the second roller blind assembly 3.
[0053] In use, the two-way sunshade provided in this embodiment allows passengers to extend the curtain 8 beyond the base 1 to block light from the car window 9 by pulling the free end of the curtain 8. At this time, the base 1 is easily deformed by torque. In some embodiments, such as... Figure 2 As shown, the partition 10 includes a first plate 11, a connecting plate 13, and a second plate 12 connected in a stepped manner in the second direction Y. The first plate 11 is close to the glass guide rail 6 and is used to connect with the glass guide rail 6.
[0054] The stepped partition 10 has strong resistance to deformation and can effectively resist the torque force on the base 1 when the curtain 8 is pulled. Figure 2 As shown, the first plate 11 is close to the glass guide rail 6 and is used to connect with the glass guide rail 6. The lengths of the connecting plate 13 and the glass guide rail 6 in the second direction Y are just enough to provide usable space for the second roller blind assembly 3.
[0055] The length of the curtain fabric 8 in the first roller blind assembly 2 is greater than the length of the curtain fabric 8 in the second roller blind assembly 3, and the space occupied by the first roller blind assembly 2 within the base 1 is greater than the space occupied by the second roller blind assembly 3. Figure 2As shown, when the base 1 is installed on the glass guide rail 6, the stepped partition 10 divides the space inside the base 1 into a first installation space 4 and a second installation space 5. The first installation space 4 is larger than the second installation space 5. The first installation space 4 is used to accommodate the first roller blind assembly 2, and the second installation space 5 is used to accommodate the second roller blind assembly 3.
[0056] In some embodiments, such as Figure 2 As shown, the base 1 also includes a first cover 14 and a second cover 15, which are distributed along the second direction Y on both sides of the partition 10. The first cover 14 is connected to the second plate 12 and covers the side of the first roller blind assembly 2 away from the partition 10, preventing passengers inside the vehicle from touching the first roller blind assembly 2 while also shielding it and improving the aesthetics of the window. A first compensation plate 18 is connected to the end of the first plate 11 away from the second plate 12, and a first outlet 16 is formed between the first cover 14 and the first compensation plate 18 for the curtain 8 of the first roller blind assembly 2 to extend out. When a passenger pulls the free end of the curtain 8 of the first roller blind assembly 2, the curtain 8 extends out from the first outlet 16. By setting the first compensation plate 18, the first outlet 16 can be shielded to a certain extent, thereby reducing the outlet area and allowing only the curtain to pass through. This prevents debris other than the curtain from entering the base and interfering with the normal stretching or retraction of the curtain, while also providing a certain degree of aesthetic appeal.
[0057] Furthermore, the end of the second plate 12 away from the first plate 11 extends along the window glass 9 in the second direction Y towards the inside of the vehicle, forming an extension 121. The first cover 14 is engaged with the extension 121 by a snap-fit (not shown in the figure). The first cover 14 is an arc-shaped cover to prevent the edges of the first cover 14 from hitting or bumping the passengers inside the vehicle.
[0058] The second cover 15 is connected to the first plate 11 and covers the side of the second roller blind assembly 3 away from the partition 10. A second opening 17 is formed between the second cover 15 and the second plate 12 for the curtain 8 of the second roller blind assembly 3 to extend out. The second cover 15 can cover the second roller blind assembly 3, preventing the second roller blind assembly 3 from being seen through the outside of the vehicle window glass 9, thereby improving the aesthetics of the vehicle window glass 9.
[0059] Because the length of the curtain fabric 8 of the first roller blind assembly 2 is greater than the length of the curtain fabric 8 of the second roller blind assembly 3, such as Figure 2As shown, when the curtain 8 of the first roller blind assembly 2 is pulled out, the base 1 is subjected to a rightward pulling force. In some embodiments, the second cover 15 includes a force-bearing plate 151 connected to the first plate 11, the force-bearing plate 151 extending along the second direction Y and used to abut against the glass guide rail 6. In this way, both the side of the glass guide rail 6 connected to the first plate 11 and the side of the glass guide rail 6 abutting against the force-bearing plate 151 can provide support for the base 1, further improving the deformation resistance of the base 1.
[0060] In some embodiments, the curtain 8 of the first roller blind assembly 2 extends from the side of the first roller blind assembly 2 closer to the second roller blind assembly 3. Compared to the method where the curtain 8 extends from the side of the first roller blind assembly 2 away from the second roller blind assembly 3, the method where the curtain 8 extends from the side of the first roller blind assembly 2 closer to the second roller blind assembly 3 keeps the curtain 8 away from the passengers in the vehicle, thus avoiding the curtain 8 affecting the riding comfort of the passengers in the vehicle.
[0061] refer to Figure 2 The second roller blind assembly 3 is located between the partition 10 and the window glass 9. In some embodiments, the curtain 8 of the second roller blind assembly 3 extends from the side of the second roller blind assembly 3 closer to the first roller blind assembly 2, so as to prevent the curtain 8 of the second roller blind assembly 3 from being too close to the window glass 9 and difficult for passengers to pull out.
[0062] Secondly, this application provides a vehicle window, which includes a glass guide rail 6 and the aforementioned two-way sunshade. The base 1 is connected to the side of the glass guide rail 6 away from the vehicle window glass 9. The vehicle window mounts the base 1 of the two-way sunshade onto the glass guide rail 6. The two curtains 8 of the two-way sunshade can provide shading for the lift-up glass and fixed glass on both sides of the glass guide rail 6. The first roller blind assembly 2 and the second roller blind assembly 3 are distributed along the second direction Y, so that the projection of the base 1 used to accommodate the first roller blind assembly 2 and the second roller blind assembly 3 along the second direction Y on the vehicle window glass 9 is small. When the curtains 8 of the first roller blind assembly 2 and the second roller blind assembly 3 are rolled up, the two-way sunshade obstructs the vehicle window glass 9 as little as possible, without affecting the normal use of the vehicle window glass 9.
[0063] like Figure 1 and Figure 3 As shown, in some embodiments, the window frame of the vehicle window is provided with multiple first connecting portions 7, and the curtain 8 of the first roller blind assembly 2 and the curtain 8 of the second roller blind assembly 3 are both provided with second connecting portions 81 that connect to the first connecting portions 7. The first connecting portion 7 can be a hook, and the second connecting portion 81 can be a locking hole. After the curtain 8 of the first roller blind assembly 2 and the curtain 8 of the second roller blind assembly 3 are extended, they can be hooked to the hook on the window frame of the vehicle window through the locking hole, which is convenient for passengers to operate and the hook and locking hole are securely connected.
