[0036] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0038] like Figures 1 to 3 As shown, the embodiment of the present application provides a curtain assembly, including a housing 3, a scissor frame 2, a driving assembly 6 and a lifting plate 11. A reel 5 and a curtain 1 connected to the reel 5 are arranged in the housing 3.

[0039] The scissor frame 2 includes a first rod 21 and a second rod 22 that are crossed and hinged. In a specific implementation, the middle portion of the first rod 21 and the middle portion of the second rod 22 can be hinged by a connecting rod rivet 25. The first rod 21 and the second rod 22 have a first end close to the reel 5 and a second end away from the reel 5. The embodiment of the present application takes the case 3 being arranged on the vehicle roof 14 as an example for explanation. The first ends of the first rod 21 and the second rod 22 are the top ends thereof, and the second ends of the first rod 21 and the second rod 22 are the bottom ends thereof.

[0040] The top end of the first rod 21 is connected to the driving assembly 6 , and the driving assembly 6 drives the top end of the first rod 21 to move along the width direction of the curtain 1 , so that the top end of the first rod 21 and the top end of the second rod 22 move away from or towards each other.

[0041] The lifting plate 11 is connected to the second end 16 of the curtain. A first slide rail 111 extending along the width direction of the curtain 1 is provided on the lifting plate 11. The bottom ends of the first rod 21 and the second rod 22 are both slidably connected to the first slide rail 111.

[0042] When implementing it specifically, Figure 2 As shown, the lifting plate 11 includes a second vertical plate and a second horizontal plate that intersect vertically, and the second horizontal plate is connected to the second end 16 of the curtain. Exemplarily, the first slide rail 111 can be a first slide groove arranged on the second vertical plate and extending along the width direction of the curtain 1. The first rivet 26 passes through the bottom end of the first rod 21 and the first slide groove, and the second rivet 27 passes through the bottom end of the second rod 22 and the first slide groove.

[0043] When the curtain assembly provided by the embodiment of the present application is in use, the housing 3 can be arranged at one end of the vehicle roof 14 close to the front of the vehicle, and the driving assembly 6 drives the top end of the first rod 21 to move along the width direction of the curtain 1, and the bottom end of the first rod 21 and the bottom end of the second rod 22 both move along the first slide rail 111. When the top end of the first rod 21 moves toward the top end of the second rod 22, as shown in FIG. Figure 1 and Figure 2 As shown, the bottom end of the first rod 21 moves away from the top end of the first rod 21 and the bottom end of the second rod 22 moves away from the top end of the second rod 22, the lifting plate 11 descends with the bottom ends of the first rod 21 and the second rod 22, and when the curtain 1 gradually unfolds to the target position as the lifting plate 1 descends, the driving assembly 6 stops working, and the projector 12 projects on the curtain 1. After the projection is completed, the driving assembly 6 drives the top end of the first rod 21 to move away from the top end of the second rod 22, the bottom end of the first rod 21 moves toward the top end of the first rod 21 and the bottom end of the second rod 22 moves toward the top end of the second rod 22, the lifting plate 11 rises with the bottom ends of the first rod 21 and the second rod 22, the curtain 1 rises with the lifting plate 11, and the reel 5 reels the curtain 1 under the action of the winding spring 8.

[0044] The curtain 1 is located on one side of the scissor frame 2. During the projection process, the lifting plate 11 can be suspended and stay at the target position between the lifting plate 11 and the shell 3 due to the support of the scissor frame 2. The lifting plate 11 will not deviate due to the support of the scissor frame 2. The back of the curtain 1 faces the scissor frame 2, and the bottom end of the curtain 1 is connected to the lifting plate 11. The lifting plate 11 and the scissor frame 2 support and limit the curtain 1 to prevent the curtain 1 from fluttering or bending due to external force or during vehicle driving, so that the curtain 1 remains flat and the projection effect is good.

[0045] For the aesthetics of the vehicle interior, an opening 32 is provided at the bottom of the housing 3, the driving assembly 6 is provided in the housing 3, the top end of the first rod 21 and the top end of the second rod 22 are both placed in the housing 3 through the opening 32, and the second end of the first rod 21 and the second end of the second rod 22 have a first use position and a second use position. In the first use position, the second end of the first rod 21 and the second end of the second rod 22 are both located on the side of the opening 32 facing the winding shaft 5, and in the second use position, the second end of the first rod 21 and the second end of the second rod 22 are both located on the side of the opening 32 away from the winding shaft 5. That is to say, after the curtain 1 is rolled up, the lifting plate 11 and part of the curtain 1 can be located outside the housing 3, or the lifting plate 11 and the curtain 1 can be located entirely inside the housing 3.

[0046] For some small cars, when the lifting plate 11 is located outside the housing 3, it is easy to cause inconvenience to the movement of people in the car. Therefore, in some embodiments, the lifting plate 11 and the opening 32 of the housing 3 can be covered and matched. Figure 3 As shown, after the curtain 1 is rolled up, the lifting plate 11 rises to the opening 32 of the housing 3 and covers the opening 32. At this time, the scissor frame 2 is stored in the housing 3. When passengers and other personnel look at the housing 3, they will not see the components in the housing 3, which does not affect the aesthetics of the vehicle. Figure 2 and Figure 3During production and processing, in order to facilitate the molding and demoulding of the shell 3, the bottom surface of the shell 3 is open, and the opening of the shell 3 is provided with a cover plate 33, and the cover plate 33 is detachably matched with the shell 3 at the opening of the shell 3, and an opening 32 is provided on the cover plate 33, and the area of ​​the opening 32 is smaller than the area of ​​the opening of the shell 3.

[0047] Since the opening 32 needs to be wide enough to allow the curtain 1 and the scissor frame 2 to extend, the length of the opening 32 in the thickness direction of the curtain 1 will be greater than the thickness of the curtain 1, and the curtain 1 will inevitably deviate slightly in the thickness direction. Figure 2 As shown, in some embodiments, a guide rod 31 is further provided in the shell 3, and the guide rod 31 extends along the width direction of the curtain 1, and a gap is formed between the guide rod 31 and the edge of the opening 32 for the curtain 1 to pass through, and the length of the gap in the thickness direction of the curtain 1 is smaller than the length of the opening 32 in the thickness direction of the curtain 1, and the curtain 1 is attached to the guide rod 31, and the curtain 1 is not easy to deviate, so that the curtain 1 extending out of the opening 32 of the shell 3 is flatter.

[0048] In some embodiments, the driving assembly 6 includes a screw 61 and a first screw nut 62 that cooperate with each other. The first screw nut 62 is connected to the top of the first rod 21. One end of the screw 61 is connected to the output shaft of the motor 64. The screw 61 is connected to the housing 3 through a screw frame 63. The motor 64 drives the screw 61 to rotate. The first screw nut 62 moves along the axial direction of the screw 61 (that is, the width direction of the curtain 1) to drive the top of the first rod 21 to move along the width direction of the curtain 1. In specific implementation, the first screw nut 62 and the top of the first rod 21 can be connected in a hinged manner. Alternatively, a groove is formed on the first screw nut 62, and the top of the first rod 21 extends into the groove on the first screw nut 62, so that the first screw nut 62 can simultaneously push and pull the first rod 21 along the width direction of the curtain 1.

[0049] The driving component 6 can also be a driving component in the form of an electric push rod, a telescopic cylinder or a piston mechanism. The movable end of the driving component 6 is connected to the top end of the first rod 21, and the fixed end of the driving component 6 is connected to the shell 3. The movable end of the driving component 6 moves along the width direction of the curtain 1, thereby driving the top end of the first rod 21 to move along the width direction of the curtain 1.

[0050] The ends of the first rod 21 and the second rod 22 can both move in the width direction of the curtain 1, so that the scissor frame 2 formed by the first rod 21 and the second rod 22 can be relatively unfolded and folded with only a small range of movement at the top of the first rod 21. This enables the lifting plate 11 to be lifted and lowered in a large range in the vertical direction. In other words, the length of the lead screw 61 only needs to meet the small range of movement of the top of the first rod 21, and the drive assembly 6 occupies a small space in the housing 3.

[0051] A second slide rail is also provided in the housing 3, and the second slide rail extends along the width direction of the curtain 1. The top end of the second rod 22 is slidably connected to the second slide rail. To prevent the top end of the second rod 22 from shaking due to lack of support, and when the top end of the first rod 21 is driven to move along the width direction of the curtain 1, the second rod 22 is likely to generate a pulling force on the lifting plate 11 in the vertical direction to tilt it, and the second slide rail supports and limits the top end of the second rod 22, so that the lifting plate 11 remains stable, and the curtain 1 also remains flat.

[0052] In specific implementation, a bracket 4 is provided in the housing 3. Figure 2 As shown, the bracket 4 includes a first vertical plate and a first horizontal plate arranged in an L-shape and intersecting with each other, and the first horizontal plate is connected to the shell 3. Exemplarily, the second slide rail can be a second slide groove arranged on the first vertical plate, and the third rivet 28 passes through the top end of the second rod 22 and the second slide groove. Both ends of the third rivet 28 are formed with large ends to prevent it from falling off.

[0053] The space inside the shell 3 is limited, and the drive assembly 6, the bracket 4 and the reel 5 must be arranged reasonably to be accommodated in the shell 3. At the same time, the volume of the shell 3 needs to meet the space requirements for its arrangement on the vehicle ceiling 14. Therefore, along the thickness direction of the curtain 1, the drive assembly 6 and the reel 5 are respectively located on both sides of the first vertical plate (not shown in the figure), and a winding spring 8 is provided between the reel 5 and the curtain 1. Both ends of the reel 5 are connected to a reel shell 7, which is connected to the shell 3, and at least part of the reel 5 is located below the first horizontal plate, so that the various components in the shell 3 are compactly arranged to save space.

[0054] Of course, the bracket 4 may not be provided. In some feasible embodiments, the driving assembly 6 includes a lead screw 61 and a first lead screw nut 62 and a second lead screw nut (not shown in the figure) matched with the lead screw 61, the first lead screw nut 62 and the second lead screw nut move away from each other along the axial direction of the lead screw 61, the first lead screw nut 62 is connected to the top end of the first rod 21, and the second lead screw nut is connected to the top end of the second rod 22.

[0055] In specific implementation, a first thread segment that cooperates with the first screw nut 62 and a second thread segment that cooperates with the second screw nut are formed on the screw 61. The spiral directions of the first thread segment and the second thread segment are opposite. When the motor 64 drives the screw 61 to rotate, the first screw nut 62 and the second screw nut can move in opposite directions along the axial direction of the screw 61.

[0056] Another embodiment of the present application provides a vehicle, the vehicle comprising a roof 14, the above-mentioned screen assembly and a projector 12 disposed on a skylight glass 13 of the roof 14. The projector 12 can be detachably connected to the skylight glass 13 via a suction cup 17.

[0057] like Figure 1 and Figure 3 As shown, a groove 9 is provided at one end of the ceiling 14 near the front of the vehicle, and the housing 3 is located in the groove 9. The top of the housing 3 can be connected to the roof sheet metal through a support 15 and a fastener. An opening is provided at the bottom of the groove 9 for the lifting plate 11 to pass through.

[0058] In the vehicle provided by the embodiment of the present application, passengers can watch movies, video chat, and project files through the projector 12 and the curtain 11, which greatly meets the entertainment, learning, and other needs of passengers. After the curtain is unfolded, it is not easy to flutter or bend and wrinkle, the projection effect is good, and the passenger experience is good.
