DETAILED DESCRIPTION

[0035] The present application embodiment provides a vehicle, see Figure 1 and Figure 2 The vehicle includes a door frame 200 and the vehicle-mounted sunshade device 100 described in any embodiment of the present application.

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

[0037] Figure 1 The door frame 200 of a door of a small car is shown. A small car refers to a car with a total mass not exceeding 4500 kg, a number of passengers (including the driver) not exceeding 9, or a length of less than 6 m.

[0038] See also Figure 1 The vehicle-mounted sunshade device 100 of the embodiment of the present application includes a first rolling curtain assembly 10 and a second rolling curtain assembly 20 .

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

[0040] That is, when the first curtain 11 is not in use, the first curtain 11 can be wound on the first winder so that the first curtain 11 is stored in the first rolling box 12. When the first curtain 11 is needed, the first curtain 11 can be pulled out of the first rolling box 12 so that the first curtain 11 is unfolded outside the first rolling box 12.

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

[0042] That is, when the second curtain 21 is not in use, the second curtain 21 can be wound on the second winder so that the second curtain 21 is stored in the second rolling box 22. When the second curtain 21 is needed, the second curtain 21 can be pulled out of the second rolling box 22 so that the second curtain 21 is unfolded outside the second rolling box 22.

[0043] It should be noted that the way the first winder winds up or releases the first curtain fabric 11 and the way the second winder winds up or releases the second curtain fabric 21 can be implemented by any method in the prior art.

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

[0045] The vehicle-mounted sunshade device 100 is arranged on one side of the door and window 200a along the vehicle's forward direction, so as to shield the door and window 200a at least by unfolding the first curtain 11, that is, only the first curtain 11 can be unfolded, or the first curtain 11 and the second curtain 21 can be unfolded at the same time. To facilitate the disassembly and assembly of the vehicle-mounted sunshade device 100, the first rolling curtain box 12 can be detachably mounted on the frame 200, for example, the first rolling curtain box 12 can be bonded or clamped to the frame 200, or can be fastened to the frame 200 by fasteners such as screws.

[0046] Specifically, the vehicle-mounted side window sunshade device 100 has three states, namely: a storage state, a semi-shielding state, and a full-shielding state.

[0047] See also Figure 2 and Figure 3 When the vehicle-mounted side window sunshade device 100 is in the storage state, the first winder winds up the first curtain 11 so that the first curtain 11 is stored in the first rolling curtain box 12, and at the same time, the second winder winds up the second curtain 21 so that the second curtain 21 is stored in the second rolling curtain box 22. That is, the first curtain 11 and the second curtain 21 are both in the storage state, and the vehicle-mounted sunshade device 100 does not block the door window 200a in any way, and the door window 200a can be fully opened.

[0048] See also Figure 4 and Figure 5 When the vehicle-mounted sunshade device 100 is in a semi-shielding state, the first winder releases the first curtain 11 to unfold the first curtain 11 outside the first rolling shutter box 12, and at the same time, the second winder winds the second curtain 21 to store the second curtain 21 in the second rolling shutter box 22. That is, in the semi-shielding state, the first curtain 11 is unfolded to shield a part of the door and window 200a, while the second curtain 21 is in a stored state and does not shield the door and window 200a, so that another part of the door and window 200a is open.

[0049] See also Figure 1 When the vehicle-mounted sunshade device 100 is in the full shielding state, the first winder releases the first curtain 11 to unfold the first curtain 11 outside the first rolling shutter box 12, and the second winder releases the second curtain 21 to unfold the second curtain 21 outside the second rolling shutter box 22. That is, in the full shielding state, both the first curtain 11 and the second curtain 21 are in the unfolded state to shield the door window 200a together.

[0050] The vehicle sunshade device 100 of the embodiment of the present application can be easily installed in a small car by setting a first roller blind assembly 10 and a second roller blind assembly 20, and the second roller blind box 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 box 22 away from the first roller blind box 12, so that the occupant can only unfold the first curtain 11 or unfold the first curtain 11 and the second curtain 21 at the same time as needed. Therefore, the door and window 200a can be shaded in a segmented manner to meet the different shading needs of the occupants. In addition, when the vehicle-mounted sunshade device 100 is not needed, the first curtain 11 and the second curtain 21 can be stored in the first rolling curtain box 12 and the second rolling curtain box 22 respectively. In this way, the first curtain 11 and the second curtain 21 can be prevented from being exposed to the outside and affecting the appearance of the vehicle, and a certain protection effect can be provided to the first curtain 11 and the second curtain 21 to better prevent the first curtain 11 and the second curtain 21 from being dirty or damaged. Therefore, the vehicle-mounted sunshade device 100 of the embodiment of the present application can be better applied to the doors and windows 200a of small cars.

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

[0052] See also Figure 1 The unfolded forms 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 be more adapted to the doors and windows 200a of different shapes. In this way, it can not only ensure that the first curtain 11 and the second curtain 21 in the unfolded state can effectively cover various 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, see Figure 1 The shape of the door window 200a of a small car is mostly triangular, that is, the height dimension of the door window 200a on one side along the vehicle's forward direction is greater than the height dimension of the other side along the vehicle's forward direction. For example, Figure 1What is shown is the door window 200a of the front door. The height dimension of the door window 200a of the front door at the rear side along the vehicle's forward direction is greater than the height dimension of the front side along the vehicle's forward direction. For the door window 200a of the rear door, 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] See also Figure 1 , the first curtain 11 has a first side 111 and a second side 112 on opposite sides of the horizontal direction 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, a first spacing H1 is provided between the first side 111 and the second side 112, and a second spacing H2 is provided between the third side 211 and the fourth side 212. For the door and window 200a in a triangular shape, the first spacing H1 may be greater than the second spacing H2. In other words, the lateral width of the first curtain 11 is greater than the lateral width of the second curtain 21, and after the first curtain 11 is unfolded, the area of ​​the door and window 200a with a relatively large height dimension can be shielded, and after the second curtain 21 is unfolded, the area of ​​the door and window 200a with a relatively small height dimension can be shielded, so that the unfolded forms of the first curtain 11 and the second curtain 21 can be better adapted to the shape of the door and window 200a.

[0055] For further information, see Figure 1 For the area of ​​the door window 200a blocked by the first curtain 11, if the height dimension of the area does not vary much along the vehicle's forward direction, the first distance H1 between the first side edge 111 and the second side edge 112 of the first curtain 11 can remain substantially unchanged.

[0056] See also Figure 1 For the area of ​​the door and window 200a blocked by the second curtain 21, if the height dimension of the area varies greatly along the forward direction of the vehicle, the unfolded second curtain 21 can also be in a form in which the second spacing H2 gradually decreases in the direction away from the second rolling shutter box 22. In other words, the second curtain 21 can also be in a triangular shape to better adapt to the shape of the area of ​​the door and window 200a blocked by the second curtain 21.

[0057] It is understandable that if the height dimension of the area of ​​the door window 200a blocked by the first curtain 11 varies greatly along the vehicle's forward direction, the unfolded first curtain 11 may also present a first spacing H1 that gradually decreases in the direction away from the first roller shutter box 12.

[0058] See also Figure 1The top contour of the door and window 200a is generally arc-shaped, and the bottom contour is generally straight. In order to further fit the top contour and bottom contour of the door and window 200a to achieve a better shielding effect, please refer to Figure 1 The first side edge 111 of the first curtain 11 can be in an arc shape protruding toward the outside of the first curtain 11 to adapt to the arc-shaped top contour of the door and window 200a, and the second side edge 112 can be in a straight line shape to adapt to the straight bottom contour of the door and window 200a.

[0059] Likewise, see Figure 1 The third side 211 of the second curtain 21 can be in an arc shape protruding toward the outside of the second curtain 21 to adapt to the arc-shaped top contour of the door and window 200a, and the fourth side 212 can be in a straight line shape to adapt to the straight bottom contour 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-mounted 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 adaptively designed according to the outer contour of the doors and windows 200a of other shapes.

[0061] In addition, 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 accordingly 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 lines or arcs.

[0062] In one embodiment, the first winder includes a first drum, and the first curtain fabric 11 is wound on the first drum. The diameter of the first drum can be gradually reduced along the axial direction, that is, the first drum can be roughly conical. Figure 1 The triangular-shaped door and window 200a shown in the figure, when the vehicle-mounted sunshade device 100 is installed, the end of the first drum with a larger diameter faces the top of the door and window 200a, and the end of the first drum with a smaller diameter faces the bottom of the door and window 200a, so that the unfolding direction of the first curtain 11 can be tilted downward relative to the forward direction of the vehicle, that is, the first curtain 11 can be unfolded obliquely downward to the door and window 200a, so that the unfolded first curtain 11 can cover more areas of the door and window 200a without increasing the lateral width dimension of the first curtain 11 (that is, the dimension of the first spacing H1).

[0063] In one embodiment, the second winder includes a second drum, and the second curtain 21 is wound on the second drum. The diameter of the second drum may also gradually decrease along the axial direction, that is, the second drum may also be substantially conical. It is understandable that if the first winder is provided with a first drum whose diameter gradually decreases along the axial direction, the end of the second drum with a larger diameter and the end of the first drum with a larger diameter are located on the same side of the vehicle-mounted sunshade device 100.

[0064] for Figure 1 The triangular-shaped door and window 200a shown in the figure, when the vehicle-mounted sunshade device 100 is installed, the end of the second drum with a larger diameter faces the top of the door and window 200a, and the end of the second drum with a smaller diameter faces the bottom of the door and window 200a, so that the unfolding direction of the second curtain 21 can be tilted downward relative to the forward direction of the vehicle, that is, the second curtain 21 can be unfolded obliquely downward to the door and window 200a, so that the unfolded second curtain 21 can cover more areas of the door and window 200a without increasing the lateral width dimension of the second curtain 21 (that is, 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 may 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 away from the first rolling shutter box 12 along the unfolding direction after the first curtain 11 is unfolded, and the first connecting end 114 is the end connected to the first winder. The first rolling shutter assembly 10 includes a clamping member 115 disposed at the first free end 113, and the clamping member 115 is clamped with the second rolling shutter box 22 to achieve the connection between the second rolling shutter box 22 and the first curtain 11.

[0066] In one embodiment, please refer to Figure 1 and Figure 6 The snap-in piece 115 can extend from one lateral side of the first curtain 11 that is perpendicular to the unfolding direction to the other opposite side, and the second rolling shutter box 22 can be slidably connected to the snap-in piece 115 so that the second rolling shutter assembly 20 can slide along the extension direction of the snap-in piece 115. That is to say, when the second rolling shutter box 22 is snapped with the snap-in piece 115, the second rolling shutter box 22 can also slide along the extension direction of the snap-in piece 115. Therefore, the position of the second rolling shutter assembly 20 can be adjusted by sliding the second rolling shutter assembly 20, thereby improving the compatibility of the vehicle-mounted sunshade device 100 with the door and window 200a.

[0067] For example, see Figure 6The snap-fitting part 115 can be provided with a connecting part 1151 and a snap-fitting part 1152 connected to the connecting part 1151. The second rolling shutter box 22 is provided with a slot 22a extending along the extension direction and having an avoidance opening 22b. The snap-fitting 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, in the process of the snap-fitting part 1152 sliding along the slot 22a, the connecting part 1151 can move along the avoidance opening 22b. Thus, the snap-fitting and sliding connection between the second rolling shutter box 22 and the snap-fitting part 115 can be realized.

[0068] In other embodiments, the second rolling shutter box 22 may be provided with a connecting portion 1151 and a snap-fit ​​portion 1152 connected to the connecting portion 1151, and the snap-fit ​​component 115 is provided with a slot 22a extending along the extension direction and having an avoidance opening 22b, and the snap-fit ​​portion 1152 is snapped into the slot 22a and can slide along the slot 22a to avoid the opening 22b and avoid the connecting portion 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 may 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 away from the second rolling shutter box 22 along the unfolding direction after the second curtain 21 is unfolded, and the second connecting end 214 is the end connected to the second winder. The vehicle-mounted sunshade device 100 further 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 rolling shutter 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] That is to say, after the first curtain 11 is unfolded outside the first rolling shutter box 12, the first positioning piece 50 on the second rolling shutter box 22 can be detachably connected to the first positioning seat 30 to keep the first curtain 11 in the unfolded state. Similarly, after the second curtain 21 is unfolded outside the second rolling shutter box 22, the second positioning piece 60 on the second curtain 21 can be detachably connected to the second positioning seat 40 to keep the second curtain 21 in the unfolded state.

[0071] The manner in which the first positioning member 50 is detachably connected to the first positioning seat 30 is not limited. For example, please refer to Figure 6 and Figure 7The first positioning seat 30 may have a first positioning groove 30a that can be expanded, and the first positioning member 50 is snap-fitted with the first positioning groove 30a, that is, the first positioning member 50 is snapped into the first positioning groove 30a, and by expanding the first positioning groove 30a, the first positioning member 50 remains in a state of snap-fitting 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.
