Technical Field

[0001] This application relates to the field of vehicle accessories technology, specifically to a vehicle-mounted sunshade device and a vehicle. Background Technology

[0002] In related technologies, to meet the sunshade needs of passengers, some cars are equipped with sunshades that can block the windows.

[0003] However, sunshades are generally suitable for medium or large buses and coaches, but not for the doors and windows of small cars, although window tinting can be used to shade the doors and windows of small cars. However, the shading effect of window tinting is limited and cannot meet the sunshading needs of passengers. Summary of the Invention

[0004] In view of this, the main objective of the embodiments of this application is to provide a vehicle-mounted sunshade device and vehicle that can be applied to the doors and windows of small cars.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] This application provides a vehicle-mounted sunshade device, including:

[0007] The first roller blind assembly includes a first curtain, a first winder, and a first roller blind box. The first winder is disposed inside the first roller blind box and connected to the first curtain, so as to store the first curtain inside the first roller blind box by winding the first curtain, or to unfold the first curtain outside the first roller blind box by releasing the first curtain.

[0008] The second roller blind assembly includes a second curtain fabric, a second winder, and a second roller blind box. The second winder is disposed inside the second roller blind box and connected to the second curtain fabric, so as to wind the second curtain fabric to house it inside the second roller blind box, or to release the second curtain fabric to unfold it outside the second roller blind box. The second roller blind box is connected to the first curtain fabric, and the second winder releases the second curtain fabric toward the side of the second roller blind box away from the first roller blind box.

[0009] In one embodiment, the first curtain has a first side and a second side on opposite sides in the transverse direction perpendicular to the unfolding direction, the second curtain has a third side on the same side as the first side and a fourth side on the same side as the second side, a first gap between the first side and the second side, and a second gap between the third side and the fourth side, wherein the first gap is greater than the second gap.

[0010] In one embodiment, the unfolded second curtain has a shape in which the second spacing gradually decreases in the direction away from the second roller blind box.

[0011] In one embodiment, the first side is arc-shaped, protruding outward from the first curtain fabric, and the second side is straight; and / or,

[0012] The third side is an arc shape that protrudes outward from the second curtain, and the fourth side is a straight line.

[0013] In one embodiment, the first winder includes a first drum on which the first fabric is wound; the diameter of the first drum gradually decreases along the axial direction; and / or,

[0014] The second winder includes a second drum, on which the second fabric is wound; the diameter of the second drum gradually decreases along the axial direction.

[0015] In one embodiment, the two opposite ends of the first curtain fabric along the unfolding direction are a first free end and a first connecting end connected to the first winder, and the first roller blind assembly includes a snap-fit ​​member disposed at the first free end, the snap-fit ​​member snapping into the second roller blind box.

[0016] In one embodiment, the snap-fit ​​extends from one side of the first curtain fabric in a transverse direction perpendicular to the unfolding direction to the opposite side, and the second roller blind box is slidably connected to the snap-fit ​​so that the second roller blind assembly can slide along the extension direction of the snap-fit.

[0017] In one embodiment, the snap-fit ​​member and one of the second roller shutter boxes are provided with a connecting portion and a snap-fit ​​portion connected to the connecting portion, while the other is provided with a slot extending along the extending direction and having a clearance opening. The snap-fit ​​portion snaps into the slot and can slide along the slot, and the clearance opening avoids the connecting portion.

[0018] In one embodiment, the two opposite ends of the second curtain along the unfolding direction are a second free end and a second connecting end connected to the second winder, respectively. The vehicle sunshade device further includes a first positioning seat, a second positioning seat, a first positioning member, and a second positioning member. The first positioning member is disposed in the second roller blind box and is detachably connected to the first positioning seat when the first curtain is in the unfolded state. The second positioning member is disposed in the second free end of the second curtain and is detachably connected to the second positioning seat when the second curtain is in the unfolded state.

[0019] In one embodiment, the first positioning seat has an expandable first positioning groove, and the first positioning part engages with the first positioning groove; and / or,

[0020] The second positioning seat has an expandable second positioning groove, and the second positioning part engages with the second positioning groove.

[0021] In one embodiment, the first positioning member is threadedly connected to the second roller shutter box; and / or,

[0022] The second roller blind assembly also includes a handle strip disposed at the second free end of the second curtain fabric, and the second positioning member is threadedly connected to the handle strip.

[0023] In one embodiment, the first roller shutter box and the second roller shutter box are magnetically attached.

[0024] This application also provides a vehicle, which includes a door frame with doors and windows and the aforementioned vehicle-mounted sunshade device. The vehicle-mounted sunshade device is disposed on one side of the doors and windows along the vehicle's direction of travel, so as to at least cover the doors and windows by means of the unfolded first curtain.

[0025] This application provides a vehicle-mounted sunshade device and a vehicle. The vehicle-mounted sunshade device, by incorporating a first roller blind assembly and a second roller blind assembly, facilitates installation in small cars. Connecting the second roller blind box to the first curtain fabric, and having the second winder release the second curtain fabric towards the side of the second roller blind box away from the first roller blind box, allows occupants to unfold only the first curtain fabric or both simultaneously as needed. This segmented approach to window and door shading caters to different occupant needs. Furthermore, when the vehicle-mounted sunshade device is not in use, the first and second curtain fabrics can be stored separately within the first and second roller blind boxes. This prevents the first and second curtain fabrics from being exposed and affecting the vehicle's aesthetics, and also provides some protection against dirt or damage. Therefore, the vehicle-mounted sunshade device of this application is well-suited for the doors and windows of small cars. Attached Figure Description

[0035] This application provides a vehicle; please refer to [the relevant documentation]. Figure 1 and Figure 2 The vehicle includes a door frame 200 and a vehicle-mounted sunshade device 100 as described in any embodiment of this application.

[0036] The door frame 200 is part of the door, and the door frame 200 has a door window 200a.

[0037] Figure 1 The image shows the door frame 200 of a small car. Small cars are defined as cars with a total mass not exceeding 4,500 kg, a passenger capacity (including the driver) not exceeding 9 people, or a length of less than 6 m.

[0038] Please see Figure 1 The vehicle sunshade device 100 in this application embodiment includes a first roller blind assembly 10 and a second roller blind assembly 20.

[0039] The first roller blind assembly 10 includes a first curtain 11, a first winder (not shown) and a first roller blind box 12. The first winder is disposed inside the first roller blind box 12 and connected to the first curtain 11 so that the first curtain 11 can be stored inside the first roller blind box 12 by winding the first curtain 11, or the first curtain 11 can be unfolded outside the first roller blind box 12 by releasing the first curtain 11.

[0040] In other words, when the first curtain 11 is not in use, it can be wound around the first winder so that it is stored inside the first roller blind box 12. When the first curtain 11 needs to be used, it can be pulled out from the first roller blind box 12 so that it is unfolded outside the first roller blind box 12.

[0041] The second roller blind assembly 20 includes a second curtain 21, a second winder (not shown), and a second roller blind box 22. The second winder is disposed inside the second roller blind box 22 and connected to the second curtain 21 so that the second curtain 21 can be stored inside the second roller blind box 22 by winding the second curtain 21, or the second curtain 21 can be unfolded outside the second roller blind box 22 by releasing the second curtain 21.

[0042] In other words, when the second curtain 21 is not in use, it can be wound around the second winder so that it is stored inside the second roller blind box 22. When the second curtain 21 is needed, it can be pulled out from the second roller blind box 22 so that it is unfolded outside the second roller blind box 22.

[0043] It should be noted that the way the first winder winds or releases the first curtain 11 and the way the second winder winds or releases the second curtain 21 can be implemented using any of the methods in the prior art.

[0044] Please continue reading. Figure 1 and Figure 2 The second roller blind 22 is connected to the first curtain 11, and the second winder releases the second curtain 21 toward the side of the second roller blind 22 away from the first roller blind 12. In other words, the second curtain 21 can be unfolded in a direction away from the first roller blind 12.

[0045] The vehicle-mounted sunshade device 100 is installed on one side of the door / window 200a along the vehicle's direction of travel, to at least block the door / window 200a with the unfolded first curtain 11. That is, only the first curtain 11 can be unfolded, or both the first curtain 11 and the second curtain 21 can be unfolded simultaneously. To facilitate the installation and removal of the vehicle-mounted sunshade device 100, the first roller blind box 12 can be detachably installed on the frame 200. For example, the first roller blind box 12 can be glued or snapped to the frame 200, or it can be fastened to the frame 200 with screws or other fasteners.

[0046] Specifically, the vehicle side window sunshade device 100 has three states: retracted state, half-covered state, and fully covered state.

[0047] Please see Figure 2 and Figure 3 When the vehicle-mounted side window sunshade 100 is in the retracted state, the first winder winds the first curtain 11, causing the first curtain 11 to be stored in the first roller blind box 12. At the same time, the second winder winds the second curtain 21, causing the second curtain 21 to be stored in the second roller blind box 22. That is to say, both the first curtain 11 and the second curtain 21 are in the retracted state, and the vehicle-mounted sunshade 100 does not obstruct the doors and windows 200a in any way, allowing the doors and windows 200a to be fully open.

[0048] Please see Figure 4 and Figure 5 When the vehicle-mounted sunshade device 100 is in a semi-shaded state, the first winder releases the first curtain 11, causing it to unfold outside the first roller blind box 12. Simultaneously, the second winder winds the second curtain 21, causing it to retract into the second roller blind box 22. In other words, in the semi-shaded state, the first curtain 11 is unfolded to partially cover the door / window 200a, while the second curtain 21 is retracted and does not cover the door / window 200a, leaving the other part of the door / window 200a open.

[0049] Please see Figure 1 When the vehicle-mounted sunshade device 100 is in the fully shading state, the first winder releases the first curtain 11, causing it to unfold outside the first roller blind 12. Simultaneously, the second winder releases the second curtain 21, causing it to unfold outside the second roller blind 22. In other words, in the fully shading state, both the first curtain 11 and the second curtain 21 are unfolded to jointly shade the door and window 200a.

[0050] The vehicle sunshade device 100 of this application embodiment, by setting a first roller blind assembly 10 and a second roller blind assembly 20, can be easily installed in a small car. By connecting the second roller blind box 22 to the first curtain 11, and releasing the second curtain 21 towards the side of the second roller blind box 22 away from the first roller blind box 12, the occupant can unfold only the first curtain 11 or unfold both the first curtain 11 and the second curtain 21 as needed. Thus, the doors and windows 200a can be blocked in a segmented manner to meet the different sunshade needs of the occupants. In addition, when the vehicle sunshade device 100 is not needed, the first curtain 11 and the second curtain 21 can be stored in the first roller blind box 12 and the second roller blind box 22 respectively. This can prevent the first curtain 11 and the second curtain 21 from being exposed and affecting the appearance of the vehicle, and can also provide a certain degree of protection for the first curtain 11 and the second curtain 21, so as to better prevent the first curtain 11 and the second curtain 21 from getting dirty or damaged. Therefore, the vehicle sunshade device 100 of this application embodiment can be well applied to the doors and windows 200a of small cars.

[0051] It should be noted that the vehicle sunshade device 100 of this application embodiment is not limited to use on the doors and windows 200a of small cars. The vehicle sunshade device 100 can also be used on any type of window of a small car, such as the front windshield and rear windshield. In addition, the vehicle sunshade device 100 of this application embodiment is not limited to use on small cars. Various windows of other types of vehicles, such as medium-sized cars and large cars, can also use the vehicle sunshade device 100 of this application embodiment as needed.

[0052] Please see Figure 1 The unfolded form of the first curtain 11 and the second curtain 21 can be designed according to the actual shape of the door and window 200a so that the first curtain 11 and the second curtain 21 can better adapt to different shapes of doors and windows 200a. Thus, it can not only ensure that the first curtain 11 and the second curtain 21 in the unfolded state can effectively cover all areas of the door and window 200a as much as possible, but also make the first curtain 11 and the second curtain 21 in the unfolded state more beautiful.

[0053] For example, please refer to Figure 1 The shapes of the doors and windows 200a in small cars are mostly triangular, meaning that the height of the door and window 200a on one side along the vehicle's direction of travel is greater than the height on the other side. For example, Figure 1The image shows the front door window 200a. The height dimension of the rear side of the front door window 200a along the vehicle's forward direction is greater than the height dimension of the front side along the vehicle's forward direction. For the rear door window 200a, the height dimension of the rear side along the vehicle's forward direction is generally smaller than the height dimension of the front side along the vehicle's forward direction.

[0054] Please see Figure 1 The first curtain 11 has a first side 111 and a second side 112 on opposite sides perpendicular to the unfolding direction. The second curtain 21 has a third side 211 on the same side as the first side 111 and a fourth side 212 on the same side as the second side 112. There is a first gap H1 between the first side 111 and the second side 112, and a second gap H2 between the third side 211 and the fourth side 212. For a door / window 200a with a near-triangular shape, the first gap H1 can be greater than the second gap H2. That is, the lateral width of the first curtain 11 is greater than the lateral width of the second curtain 21. When the first curtain 11 is unfolded, it can cover the area of ​​the door / window 200a with a relatively large height dimension, and when the second curtain 21 is unfolded, it can cover the area of ​​the door / window 200a with a relatively small height dimension. Thus, the unfolding shape of the first curtain 11 and the second curtain 21 can better adapt to the shape of the door / window 200a.

[0055] Further, please refer to Figure 1 For the area of ​​the door and window 200a that is covered by the first curtain 11, if the height dimension of the area does not change much along the direction of vehicle travel, the first distance H1 between the first side 111 and the second side 112 of the first curtain 11 can remain approximately unchanged.

[0056] Please see Figure 1 For the area of ​​the door and window 200a that is covered by the second curtain 21, if the height of the area varies greatly along the direction of vehicle travel, the unfolded second curtain 21 can also be in the form of a second spacing H2 that gradually decreases in the direction away from the second roller shutter box 22. In other words, the second curtain 21 can also be in a triangular shape to better fit the shape of the area of ​​the door and window 200a covered by the second curtain 21.

[0057] It is understandable that if the height of the area of ​​the door and window 200a covered by the first curtain 11 varies greatly along the direction of vehicle travel, the unfolded first curtain 11 can also be in the form of the first spacing H1 gradually decreasing in the direction away from the first roller shutter box 12.

[0058] Please see Figure 1The top profile of door and window 200a is generally curved, and the bottom profile is generally straight. To further conform to the top and bottom profiles of door and window 200a for better shading, please refer to [the relevant documentation / reference]. Figure 1 The first side 111 of the first curtain 11 can be an arc shape protruding outward from the first curtain 11 to match the arc-shaped top profile of the door and window 200a, and the second side 112 can be a straight line to match the straight bottom profile of the door and window 200a.

[0059] Similarly, please see Figure 1 The third side 211 of the second curtain 21 can be an arc shape protruding outward from the second curtain 21 to match the arc-shaped top profile of the door and window 200a, and the fourth side 212 can be a straight line to match the straight bottom profile of the door and window 200a.

[0060] It should be noted that the first side 111, the second side 112, the third side 211 and the fourth side 212 are not limited to the above-mentioned shapes. When the vehicle sunshade device 100 is applied to doors and windows 200a of other shapes, the first side 111, the second side 112, the third side 211 and the fourth side 212 can be adapted to the outer contour of the doors and windows 200a of other shapes.

[0061] In other embodiments, the shapes of the first side 111, the second side 112, the third side 211, and the fourth side 212 may not change with the outer contour of the door and window 200a. For example, the first side 111, the second side 112, the third side 211, and the fourth side 212 may all be straight or curved.

[0062] In one embodiment, the first winder includes a first drum on which the first fabric 11 is wound. The diameter of the first drum may gradually decrease along the axial direction; that is, the first drum may be approximately conical. Figure 1 The door and window 200a shown is in a triangular shape. When the vehicle sunshade device 100 is installed, the larger diameter end of the first roller faces the top of the door and window 200a, and the smaller diameter end faces the bottom of the door and window 200a. This allows the unfolding direction of the first curtain 11 to be tilted downward relative to the vehicle's forward direction. In other words, the first curtain 11 can be unfolded diagonally downward towards the door and window 200a. This allows the unfolded first curtain 11 to cover more areas of the door and window 200a without increasing the lateral width of the first curtain 11 (i.e., the size of the first spacing H1).

[0063] In one embodiment, the second winder includes a second spool on which the second curtain 21 is wound. The diameter of the second spool may also gradually decrease along the axial direction, that is, the second spool may also be approximately conical. It is understood that if the first winder is provided with a first spool whose diameter gradually decreases along the axial direction, then the larger diameter end of the second spool is located on the same side of the vehicle sunshade device 100 as the larger diameter end of the first spool.

[0064] for Figure 1 The door and window 200a shown is in a triangular shape. When the vehicle sunshade device 100 is installed, the larger diameter end of the second roller faces the top of the door and window 200a, and the smaller diameter end faces the bottom of the door and window 200a. This allows the unfolding direction of the second curtain 21 to be tilted downward relative to the vehicle's forward direction. In other words, the second curtain 21 can be unfolded diagonally downward towards the door and window 200a. This also allows the unfolded second curtain 21 to cover more areas of the door and window 200a without increasing the lateral width dimension of the second curtain 21 (i.e., the dimension of the second spacing H2).

[0065] In one embodiment, please refer to Figure 1 For ease of description, the two opposite ends of the first curtain 11 along the unfolding direction can be referred to as the first free end 113 and the first connecting end 114, respectively. The first free end 113 is the end of the first curtain 11 that is away from the first roller blind box 12 along the unfolding direction after it is unfolded, and the first connecting end 114 is the end that is connected to the first winder. The first roller blind assembly 10 includes a snap-fit ​​member 115 disposed at the first free end 113. The snap-fit ​​member 115 connects the second roller blind box 22 to the first curtain 11 by snapping with the second roller blind box 22.

[0066] In one embodiment, please refer to Figure 1 and Figure 6 The snap-fit ​​115 can extend from one side of the first curtain 11 perpendicular to the unfolding direction to the opposite side. The second roller blind box 22 can be slidably connected to the snap-fit ​​115 so that the second roller blind assembly 20 can slide along the extension direction of the snap-fit ​​115. That is, while the second roller blind box 22 is snapped with the snap-fit ​​115, the second roller blind box 22 can also slide along the extension direction of the snap-fit ​​115. Thus, the position of the second roller blind assembly 20 can be adjusted by sliding the second roller blind assembly 20, thereby improving the compatibility between the vehicle sunshade device 100 and the door and window 200a.

[0067] For example, please refer to Figure 6The snap-fit ​​component 115 can be provided with a connecting part 1151 and a snap-fit ​​part 1152 connected to the connecting part 1151. The second roller blind box 22 is provided with a slot 22a that extends along the extension direction and has an avoidance opening 22b. The snap-fit ​​part 1152 is snapped into the slot 22a and can slide along the slot 22a. The avoidance opening 22b avoids the connecting part 1151. That is to say, during the process of the snap-fit ​​part 1152 sliding along the slot 22a, the connecting part 1151 can move along the avoidance opening 22b. Thus, the snap-fit ​​and sliding connection between the second roller blind box 22 and the snap-fit ​​component 115 can be realized.

[0068] In other embodiments, the second roller shutter box 22 may be provided with a connecting part 1151 and a snap-fit ​​part 1152 connected to the connecting part 1151. The snap-fit ​​part 115 is provided with a slot 22a extending in the extension direction and having an avoidance opening 22b. The snap-fit ​​part 1152 is snapped into the slot 22a and can slide along the slot 22a, while the avoidance opening 22b avoids the connecting part 1151.

[0069] In one embodiment, please refer to Figure 1 For ease of description, the two opposite ends of the second curtain 21 along the unfolding direction can be referred to as the second free end 213 and the second connecting end 214, respectively. The second free end 213 is the end of the second curtain 21 that is away from the second roller blind box 22 along the unfolding direction after it is unfolded, and the second connecting end 214 is the end that is connected to the second winder. The vehicle sunshade device 100 also includes a first positioning seat 30, a second positioning seat 40, a first positioning member 50, and a second positioning member 60. The first positioning member 50 is disposed on the second roller blind box 22 and is detachably connected to the first positioning seat 30 when the first curtain 11 is in the unfolded state. The second positioning member 60 is disposed on the second free end 213 of the second curtain 21 and is detachably connected to the second positioning seat 40 when the second curtain 21 is in the unfolded state.

[0070] In other words, after the first curtain 11 is unfolded outside the first roller blind 12, the first positioning member 50 on the second roller blind 22 can be detachably connected to the first positioning seat 30 so that the first curtain 11 remains unfolded. Similarly, after the second curtain 21 is unfolded outside the second roller blind 22, the second positioning member 60 on the second curtain 21 can be detachably connected to the second positioning seat 40 so that the second curtain 21 remains unfolded.

[0071] The manner in which the first positioning member 50 and the first positioning seat 30 are detachably connected is not limited. For example, please refer to [link to example]. Figure 6 and Figure 7The first positioning seat 30 may have an expandable first positioning groove 30a, and the first positioning member 50 is engaged with the first positioning groove 30a. That is, the first positioning member 50 is engaged in the first positioning groove 30a, and by expanding the first positioning groove 30a, the first positioning member 50 is kept engaged with the first positioning groove 30a.

[0072] The manner in which the second positioning member 60 is detachably connected to the second positioning seat 40 is not limited. For example, please refer to [link to example]. Figure 6 and Figure 7 The second positioning seat 40 may have an expandable second positioning groove 40a, and the second positioning member 60 is engaged with the second positioning groove 40a. That is, the second positioning member 60 is engaged in the second positioning groove 40a, and by expanding the second positioning groove 40a, the second positioning member 60 is kept engaged with the second positioning groove 40a.

[0073] In other embodiments, the first positioning seat 30 and the first positioning member 50, and the second positioning seat 40 and the second positioning member 60, can also be engaged in other ways. For example, the first positioning member 50 can be a hook, and the first positioning seat 30 can be provided with a slot, or the second positioning seat 40 can be a hook, and the second positioning member 60 can be provided with a slot, with the hook and slot engaging in a snap-fit ​​relationship.

[0074] In other embodiments, the first positioning seat 30 and the first positioning member 50, and the second positioning seat 40 and the second positioning member 60, can also be detachably connected by other means such as plugging or magnetic attraction.

[0075] In one embodiment, please refer to Figure 6 The first positioning member 50 can be threadedly connected to the second roller blind box 22. The first positioning member 50 is provided with external threads and screwed into the second roller blind box 22.
