DETAILED DESCRIPTION

[0042] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0043] Reference below Figures 1-15 A screen device 100 for a vehicle according to an embodiment of the present invention will be described.

[0044] Among them, the screen device 100 is set in the passenger compartment of the vehicle and connected to the top wall of the passenger compartment. The screen device 100 can form a projection area in the passenger compartment. The projection equipment (such as: projector and equipment with projection function, etc.) can project the picture into the projection area formed by the screen device 100 to present the image to the passengers in the passenger compartment, meeting the user's use needs of viewing images in the passenger compartment, such as: watching movies, watching PPT (PowerPoint: slides), etc.

[0045] The screen device 100 according to the embodiment of the present application includes: a shell assembly 1 , a screen assembly 2 , a privacy curtain assembly 3 , a first driving device 4 and a second driving device 5 .

[0046] Specifically, the shell assembly 1 includes an upper shell 11 and a lower shell 12. The upper shell 11 is installed on the top wall of the passenger compartment, and the lower shell 12 is arranged below the upper shell 11. The curtain assembly 2 is wound with a curtain 21 and installed on the upper shell 11. The curtain unfolding end 211 of the curtain 21 is connected to the lower shell 12. The privacy curtain assembly 3 is wound with a privacy curtain 31 and installed on the upper shell 11. The privacy curtain unfolding end 311 of the privacy curtain 31 is connected to the lower shell 12.

[0047] The first drive device 4 is mounted on the housing assembly 1 and is used to drive the lower housing 12 to rise and fall vertically relative to the upper housing 11, thereby driving the unfolded end 211 of the screen and the unfolded end of the privacy curtain 31 downwardly through the lower housing 12, thereby synchronously pulling down and unfolding the screen 21 and the privacy curtain 31. Thus, the first drive device 4 cooperates with the housing assembly 1 to achieve the synchronous unfolding of the screen 21 and the privacy curtain 31.

[0048] Furthermore, a second drive device 5 is installed on the shell assembly 1, and the second drive device 5 is used to drive the privacy curtain assembly 3 to translate along the Y direction of the vehicle, thereby adjusting the position of the privacy curtain 31 relative to the curtain 21 in the Y direction, so as to adjust the privacy curtain 31 to an area suitable for blocking the gap between the curtain 21 and the passenger compartment, thereby improving the privacy protection effect after the curtain device 100 is unfolded, and preventing light from passing through the gap between the curtain device 100 and the side wall of the passenger compartment and affecting the projection presentation effect on the curtain 21.

[0049] The "Y direction" of the vehicle refers to the left and right direction of the vehicle.

[0050] It's understandable that some vehicle models currently incorporate screens 21 within the passenger compartment to enhance user experience. For example, these screens 21 are installed in the passenger compartment to project images onto the screens 21, allowing passengers to view the images displayed on the screens 21 and enhancing the passenger experience. These screens 21 are typically located behind the driver's and front passenger's seats and are used to present images to rear-seat passengers. Furthermore, when deployed, the screens 21 are typically positioned parallel to the YZ plane, allowing rear-seat passengers to view the images displayed on the screens 21 from back to front.

[0051] In related technologies, the curtain 21 is usually arranged in the middle area of ​​the vehicle in the Y direction, resulting in a gap between the curtain 21 and the side walls of the passenger compartment on both sides in the Y direction. The light in front of the vehicle can pass through the gap to the rear area (i.e., the viewing area where the passengers are located) and affect the viewing effect of the image on the curtain 21.

[0052] It is understandable that if the light from the front of the vehicle passes through the gap and shines into the rear space of the passenger compartment, the areas on both sides of the screen 21 in the Y direction will be brighter, thereby affecting the rear passengers' experience of viewing the image presented on the screen 21 in front of them.

[0053] In the screen device 100 of the present application, the screen device 100 includes a screen assembly 2 and a privacy curtain assembly 3. The screen 21 in the screen assembly 2 is used to present images, and the privacy curtain 31 in the privacy curtain assembly 3 is suitable for moving to the gap between the screen 21 and the passenger compartment after unfolding, so that the privacy curtain 31 can block the gap between the screen 21 and the passenger compartment in the Y direction, so that the front and rear rows of the vehicle can be separated by the screen 21 and the privacy curtain 31, providing the rear passengers with a private environment suitable for business negotiations, watching movies and working, thereby improving the privacy protection effect of the screen device 100.

[0054] Among them, the lower shell 12 can drive the curtain 21 and the privacy curtain 31 to unfold synchronously, and the second driving device 5 can drive the privacy curtain 31 to translate along the Y direction when the privacy curtain 31 is in the unfolded state, so that the privacy curtain 31 moves to a position suitable for blocking the gap between the curtain 21 and the side wall of the passenger compartment, thereby blocking the gap between the curtain 21 and the passenger compartment in the Y direction through the privacy curtain 31.

[0055] Combine Figure 1 and Figure 2 As shown, the privacy curtain 31 is set on the side of the screen 21 away from the projection surface, so that the projection area of ​​the screen 21 can be exposed to the rear side, avoiding the privacy curtain 31 blocking the projection area formed on the screen 21 to ensure the viewing experience of the passengers.

[0056] like Figure 10 As shown, the lower housing 12 moves downward relative to the upper housing 11, and the lower housing 12 can drive the curtain 21 and the privacy curtain 31 ( Figure 10 (not shown) is unfolded synchronously, so that the screen 21 is fully presented in front of the rear passengers, making it easier for the rear passengers to watch the image presented on the screen 21; Figure 11 As shown, the privacy curtain 31 extends from the front side of the screen 21 (i.e., the side facing away from the rear passengers viewing the screen 21) to both sides of the screen 21. The privacy curtain 31 can block the gap between the screen 21 and the passenger compartment on both sides in the Y direction, thereby separating the front and rear areas of the passenger compartment through the screen device 100, so as to prevent light from passing through the gap between the screen 21 and the passenger compartment to the rear side while providing a more private space for the rear passengers, thereby improving the rear passengers' riding and viewing experience.

[0057] It is understood that in the curtain assembly 2, the curtain assembly 2 has a first retracting portion, which is used to wind the curtain 21. When the lower housing 12 moves downward relative to the upper housing 11, the lower housing 12 pulls the curtain 21 out by pulling the curtain extension end 211. When the lower housing 12 moves upward relative to the upper housing 11, the first retracting portion can synchronously retract the curtain 21 with the upward movement of the lower housing 12, thereby achieving the winding and unwinding of the curtain 21. Similarly, the privacy curtain assembly 3 can also achieve the winding and unwinding of the privacy curtain 31 by providing a second retracting portion, similar to the winding method of the curtain 21 described above.

[0058] According to the screen device 100 of the embodiment of the present application, the lower shell 12 is driven by the first driving device 4 to move relative to the upper shell 11 to realize the retraction and extension of the screen 21 and the privacy curtain 31, and when the privacy curtain 31 is in the unfolded state, the privacy curtain 31 can be driven by the second driving device 5 to translate along the Y direction to adjust the lateral position of the privacy curtain 31 relative to the screen 21. The privacy curtain 31 is arranged in a position where it can block the gap between the screen 21 and the side wall of the passenger compartment, which helps to improve the separation effect of the screen device 100 on the front and rear rows of the passenger compartment, can ensure the privacy needs of the rear passengers, and can improve the viewing experience of the rear passengers of the picture presented on the screen 21.

[0059] Combine Figure 4 and Figure 5 As shown, in some embodiments of the present application, the first driving device 4 includes: a connecting rod assembly 41 and a first driving part 42 .

[0060] Among them, the connecting rod assembly 41 includes a first connecting rod 411 and a second connecting rod 412, one end of the first connecting rod 411 is rotatably connected to the upper shell 11, one end of the second connecting rod 412 is connected to the lower shell 12, and the other end of the first connecting rod 411 and the other end of the second connecting rod 412 are rotatably connected to form a connecting rod mechanism between the upper shell 11 and the lower shell 12.

[0061] It should be noted that the second connecting rod 412 is also connected to the lower shell 12 in a rotatable manner, and the rotation axis of the first connecting rod 411 relative to the upper shell 11, the rotation axis of the lower shell 12 relative to the lower shell 12, and the rotation axis of the first connecting rod 411 relative to the second connecting rod 412 are arranged parallel to each other, so that the first connecting rod 411 and the second connecting rod 412 can be folded or unfolded in the same plane.

[0062] Furthermore, the first driving part 42 is arranged on the upper shell 11, and the first driving part 42 is connected to the first connecting rod 411. The first driving part 42 is used to drive the first connecting rod 411 to swing, so as to drive the second connecting rod 412 to move through the first connecting rod 411, and further drive the lower shell 12 to move through the second connecting rod 412, thereby realizing the position adjustment of the lower shell 12 relative to the upper shell 11.

[0063] Combine Figure 2 and Figure 4 As shown, the first link 411 and the second link 412 are arranged in a V shape, and the opening of the V is facing the side wall of the passenger compartment, so that the first link 411 and the second link 412 can be retracted inward (close to the center axis of the vehicle) when folded together, avoiding the link assembly 41 occupying too much external space and affecting the storage of the curtain device 100.

[0064] Specifically, when the first driving part 42 drives the first connecting rod 411 to swing downward relative to the upper shell 11, the angle between the first connecting rod 411 and the second connecting rod 412 in the V-shaped structure gradually increases, and the opening of the V-shaped structure also increases accordingly, so as to unfold the connecting rod assembly 41 and realize the downward movement of the lower shell 12 relative to the upper shell 11, so that the curtain 21 and the privacy curtain 31 can be driven to unfold downward synchronously through the lower shell 12; when the first driving part 42 drives the first connecting rod 411 to swing upward relative to the upper shell 11, the angle between the first connecting rod 411 and the second connecting rod 412 in the V-shaped structure gradually decreases, and the opening of the V-shaped structure also decreases accordingly, so as to fold the connecting rod assembly 41 and realize the upward movement of the lower shell 12 relative to the upper shell 11, so that the curtain 21 and the privacy curtain 31 can be synchronously retracted, and it is convenient for the connecting rod assembly 41 to be stored at the curtain device 100.

[0065] like Figure 5 As shown, in a further embodiment of the present application, the first driving part 42 includes: a first driving screw 421 , a first sliding foot 422 , a first driving motor 423 and a driving connecting rod 424 .

[0066] Among them, the first drive screw 421 is threadedly engaged with the first slide 422, and the first drive motor 423 is installed on the upper shell 11, and the first drive motor 423 is configured to drive the first drive screw 421 to rotate to drive the first slide 422 to translate along the Y direction of the vehicle, so that the driving force (such as pulling force or pushing force) in the Y direction can be output through the first slide 422. At the same time, the two ends of the drive link 424 are rotatably connected to the first slide 422 and the first connecting rod 411 respectively, and the drive link 424 is used to drive the first connecting rod 411 to swing, so as to transmit the driving force to the first connecting rod 411 through the drive link 424, thereby realizing the swing drive of the first connecting rod 411.

[0067] Specifically, the first drive motor 423 is used to drive the first drive screw 421 to rotate, and the first drive screw 421 is threadedly engaged with the first slide 422, and the drive connecting rod 424 can limit the rotation of the first slide 422, so that the first drive motor 423 can be used to drive the first slide 422 to move in the Y direction, so as to output the driving force in the Y direction through the first slide 422.

[0068] Furthermore, the first sliding foot 422 can drive the driving link 424 to move, and the driving link 424 is connected between the first sliding foot 422 and the first link 411, so that the driving force can be transmitted to the first link 411 through the driving link 424, and the first link 411 is driven by the driving link 424 to drive the second link 412 to move, so as to realize the unfolding and folding action of the link assembly 41.

[0069] In some embodiments of the present application, the first drive motor 423 is arranged in the middle position of the upper shell 11 in the Y direction. When the drive motor drives the first slide 422 to move outward along the Y direction, the first slide 422 drives the drive link 424 to drive the first link 411 to swing downward relative to the upper shell 11, so as to drive the first link 411 and the second link 412 to unfold; when the drive motor drives the first slide 422 to move inward along the Y direction (that is, close to the side of the first drive motor 423), the first slide 422 drives the drive link 424 to drive the first link 411 to swing upward relative to the upper shell 11, so as to drive the first link 411 and the second link 412 to fold.

[0070] Among them, the driving force output stability of the screw mechanism formed by the first driving screw 421 and the first sliding foot 422 is good, and the movement reliability of the connecting rod assembly 41 driven by the driving connecting rod 424 is high, which can improve the stability and reliability of the first driving device 4 driving the lower shell 12 to move relative to the upper shell 11, and enable the lower shell 12 to drive the curtain 21 and the privacy curtain 31 to gradually unfold, and the unfolding action is smooth, which can effectively avoid problems such as jamming of the curtain 21 or the privacy curtain 31 during the unfolding process.

[0071] Combine Figure 4 and Figure 5 As shown, in some embodiments of the present application, the first drive device 4 includes two groups of connecting rod assemblies 41, and the first drive part 42 is provided with two groups of first drive screws 421, first sliding feet 422 and driving connecting rods 424 respectively connected to the two groups of connecting rod assemblies 41, and the first drive part 42 can drive the two groups of connecting rod assemblies 41 to move synchronously, so as to drive the two groups of connecting rod assemblies 41 to unfold or fold synchronously, thereby improving the stability of the movement process of the lower shell 12 relative to the upper shell 11.

[0072] Reference Figure 4As shown, when two sets of connecting rod assemblies 41 are provided in the first drive device 4, the two sets of connecting rod assemblies 41 are respectively connected between the upper shell 11 and the lower shell 12, so that the lower shell 12 can be driven to move relative to the upper shell 11 through the synchronous expansion or folding of the two sets of connecting rod assemblies 41, which helps to improve the stability of the movement process of the lower shell 12 relative to the upper shell 11.

[0073] In the two groups of connecting rod assemblies 41, the connection positions of the two first connecting rods 411 and the upper shell 11 are arranged at intervals along the Y direction, and the connection positions of the two second connecting rods 412 and the lower shell 12 are arranged at intervals along the Y direction, so that the connection positions of the two groups of connecting rod assemblies 41 and the shell assembly 1 are arranged at four points.

[0074] Preferably, the two sets of connecting rod assemblies 41 are symmetrically arranged on either side of the first drive motor 423 to enhance the stability of the lower housing 12 when driven, ensuring that the lower housing 12 remains stable and prevents deflection during movement relative to the upper housing 11. Simultaneously, the two sets of first drive screws 421, first sliding feet 422, and drive connecting rods 424 are also symmetrically arranged on either side of the first drive motor 423.

[0075] In a further embodiment of the present application, the first drive motor 423 is constructed to simultaneously drive the two first drive screws 421 to move, thereby realizing the synchronous driving of two groups of drive components (each group of drive components includes a first drive screw 421, a first slide foot 422 and a drive connecting rod 424) by only one drive motor (i.e., the first drive motor 423), which helps to improve the compactness of the arrangement between the various devices in the upper shell 11 and avoid space waste.

[0076] like Figure 4 and Figure 5 As shown, in some embodiments of the present application, the privacy curtain assembly 3 further includes a first sleeve 32 and a second sleeve 33 .

[0077] Among them, the first sleeve 32 is arranged on the upper shell 11, the second sleeve 33 is sleeved on the first sleeve 32, and the second sleeve 33 is connected to one end of the privacy curtain 31, the second sleeve 33 is connected to the second driving device 5, the second driving device 5 can drive the second sleeve 33 to slide relative to the first sleeve 32 along the Y direction, and the second sleeve 33 can rotate synchronously with the first sleeve 32 to reel in or unreel the privacy curtain 31.

[0078] like Figure 12 As shown, the second sleeve 33 is sleeved on the first sleeve 32, and the second sleeve 33 can slide in the Y direction relative to the first sleeve 32, so as to drive the privacy curtain 31 to move synchronously in the Y direction through the second sleeve 33, thereby realizing the position adjustment of the privacy curtain 31 relative to the upper shell 11 in the Y direction.

[0079] When the second sleeve 33 moves outward along the Y direction relative to the first sleeve 32, the second sleeve 33 will drive the privacy curtain 31 to move outward synchronously, thereby adjusting the privacy curtain 31 to a position suitable for blocking the gap between the curtain 21 and the side wall of the passenger compartment; when the second sleeve 33 moves inward along the Y direction relative to the first sleeve 32, the second sleeve 33 will drive the privacy curtain 31 to move inward synchronously, thereby adjusting the privacy curtain 31 to a position overlapping with the curtain 21, so as to facilitate the retraction of the privacy curtain 31.

[0080] It is understood that the second sleeve 33 rotates synchronously with the first sleeve 32, so the first sleeve 32 needs to be rotatably mounted on the upper housing 11 to meet the rotation requirements of the first sleeve 32 and the second sleeve 33. At the same time, the privacy curtain 31 is connected to the second sleeve 33, and the privacy curtain 31 can be retracted during the rotation of the second sleeve 33.

[0081] It should be noted that the privacy curtain unfolding end 311 of the privacy curtain 31 is connected to the lower shell 12, and the other end of the privacy curtain 31 is fixedly connected to the second sleeve 33. When the lower shell 12 moves downward relative to the upper shell 11, the lower shell 12 can drive the privacy curtain unfolding end 311 to move downward to unfold the privacy curtain 31, and under the pull of the privacy curtain 31, the second sleeve 33 drives the first sleeve 32 to rotate synchronously to unwind the privacy curtain 31. At this time, the second retracting part located in the privacy curtain assembly 3 accumulates energy; when the lower shell 12 moves upward relative to the upper shell 11, the lower shell 12 can drive the privacy curtain unfolding end 311 to move upward. At this time, the second retracting part releases energy and drives the first sleeve 32 and the second sleeve 33 to rotate, so that the privacy curtain 31 is retracted and wrapped around the first sleeve 32 and the second sleeve 33, thereby achieving the retraction of the privacy curtain 31.

[0082] Among them, the above-mentioned "first retracting part" and "second retracting part" can be constructed as energy storage components such as torsion springs and spring leaves. There is no specific limitation on the structure and arrangement position of the first retracting part and the second retracting part. It is sufficient to be able to drive the reel structure (such as: the above-mentioned first sleeve 32 and second sleeve 33) to realize the retracting function.

[0083] Reference Figure 12 As shown, in some embodiments of the present application, a rib 321 is formed on the outer peripheral wall of the first sleeve 32, and the rib 321 protrudes toward one side of the second sleeve 33 along the radial direction of the first sleeve 32. A groove is formed on the inner peripheral wall of the second sleeve 33 to cooperate with the rib 321, and at least part of the rib 321 extends into the groove to limit the second sleeve 33 in the circumferential direction relative to the first sleeve 32, so that the second sleeve 33 can rotate synchronously with the first sleeve 32 around the central axis of the sleeve structure (i.e., the first sleeve 32 and the second sleeve 33).

[0084] In a further embodiment of the present application, there are multiple ribs 321 on the first sleeve 32, and the multiple ribs 321 are arranged at intervals along the circumferential direction of the first sleeve 32. Correspondingly, the inner wall of the second sleeve 33 is also formed with multiple grooves to enhance the circumferential limiting effect of the first sleeve 32 and the second sleeve 33.

[0085] like Figure 12 As shown, in some embodiments of the present application, the rib 321 extends along the axial direction of the first sleeve 32 on the outer peripheral wall of the first sleeve 32, so as to guide the sliding of the second sleeve 33 relative to the first sleeve 32 through the rib 321, so as to improve the stability of the sliding process of the second sleeve 33 relative to the first sleeve 32.

[0086] Preferably, the axial direction of the first sleeve 32 is arranged parallel to the Y direction of the vehicle.

[0087] Combine Figure 9 and Figure 12 As shown, in some embodiments of the present application, the second driving device 5 includes a second driving screw 51 , a second sliding foot 52 and a second driving motor 53 .

[0088] Among them, the second driving screw 51 is arranged parallel to the Y direction, the second sliding foot 52 is threadedly engaged with the second driving screw 51, and the second sliding foot 52 is connected to the second sleeve 33, and the second sliding foot 52 can drive the second sleeve 33 to translate along the Y direction, the second driving motor 53 is arranged at the upper shell 11, and the second driving motor 53 is used to drive the second driving screw 51 to rotate.

[0089] It is understandable that a threaded hole is formed on the second slide foot 52 and is threadedly engaged with the second drive screw 51. When the second motor drives the second drive screw 51 to rotate, the second drive screw 51 is threadedly engaged with the second slide foot 52 to drive the second slide foot 52 to move along the axial direction of the second drive screw 51 (i.e., the Y direction). The second slide foot 52 can drive the second sleeve 33 to move synchronously to achieve position adjustment of the second sleeve 33 relative to the first sleeve 32 in the Y direction, thereby allowing the privacy curtain 31 to be translated along the Y direction.

[0090] like Figure 12 As shown, in a further embodiment of the present application, the upper shell 11 is provided with a guide groove 111 extending along the Y direction, and the second slide foot 52 is provided with a guide protrusion 521, which extends into the guide groove 111, and the guide groove 111 can be guided and cooperated with the guide protrusion 521 to assist the second slide foot 52 to translate relative to the upper shell 11 along the Y direction.

[0091] In some embodiments of the present application, a flange 331 is provided on the outer wall of the second sleeve 33, and the flange 331 protrudes along the radial direction of the second sleeve 33. A clamping groove 522 is provided on the second slide foot 52, and the clamping groove 522 is clamped and cooperated with the flange 331 in the Y direction, so that the second slide foot 52 can drive the second sleeve 33 to translate along the Y direction through the flange 331.

[0092] like Figure 12 As shown, the flange 331 is formed at the inner end of the second sleeve 33 in the axial direction, so that the flange 331 can be arranged on the inner side of the privacy curtain 31 to prevent interference between the flange 331 and the privacy curtain 31, and the flange 331 can limit the privacy curtain 31 wound on the second sleeve 33 to prevent the privacy curtain 31 from moving.

[0093] Reference Figure 12 As shown, in a further embodiment of the present application, the clamping groove 522 extends along the circumferential direction of the second sleeve 33. The clamping groove 522 is arranged in a U-shape, so that the second sleeve 33 can be inserted through the opening of the U-shaped structure, and the flange 331 is embedded in the clamping groove 522 to achieve a clamping fit between the second sliding foot 52 and the second sleeve 33. The installation and fit of the second sleeve 33 and the second sliding foot 52 are simple.

[0094] Combine Figure 7 and Figure 8 As shown, in some embodiments of the present application, the lower shell 12 is provided with a slide groove 121 extending along the Y direction, and the privacy curtain assembly 3 also includes a slide rod 34, which is connected to the other end of the privacy curtain 31 (that is, the above-mentioned privacy curtain unfolding end 311), and the slide rod 34 can slide with the slide groove 121.

[0095] Combine Figure 2 、 Figure 10 and Figure 11 As shown, during the opening process of the curtain device 100, the curtain 21 and the privacy curtain 31 are synchronously unfolded downward, and after the curtain 21 and the privacy curtain 31 are unfolded downward into place, the privacy curtain 31 is driven to translate along the Y direction by the second driving device 5 to adjust part of the privacy curtain 31 to be suitable for both sides of the curtain 21 in the Y direction.

[0096] Among them, the upper end of the privacy curtain 31 (that is, the end of the privacy curtain 31 connected to the second sleeve 33) is driven by the second sleeve 33 to achieve Y-direction translation, and the lower end of the privacy curtain 31 (that is, the unfolded end 311 of the privacy curtain) can slide along the Y-direction relative to the lower shell 12 under the action of the sliding rod 34, thereby achieving the overall translation of the privacy curtain 31 along the Y-direction and preventing wrinkles from forming on the privacy curtain 31.

[0097] It can be understood that the unfolded end 311 of the privacy curtain is slidably set on the lower shell 12 through the sliding rod 34, which can reduce the difficulty of adjusting the position of the unfolded end 311 of the privacy curtain, so that the position adjustment of the privacy curtain 31 in the Y direction is smooth.

[0098] like Figure 13 As shown, in a further embodiment of the present application, a driving gear 511 is provided on the second driving screw 51, and the driving gear 511 rotates synchronously with the second driving screw 51, and the second driving device 5 also includes a wire wheel 54, a driven gear 55 and a guide wheel 56.

[0099] Reference Figure 13 As shown, a pull wire (not shown) is wound around the pulley 54, which is used to reel in or release the pull wire, and the pull wire is connected to the slide rod 34 to drive the slide rod 34 to slide on the lower shell 12 through the pull wire, thereby realizing position adjustment of the slide rod 34 on the lower shell 12.

[0100] Furthermore, the driven gear 55 is power-connected to the driving gear 511, and is used to drive the wire pulley 54 to rotate, thereby realizing the wire pulley 54's winding and releasing action on the wire pulley. The guide wheel 56 is provided on the connecting rod assembly 41, and is used to guide the wire pulley so that the wire pulley can slide smoothly. When the second driving device 5 drives the second sleeve 33 to translate outward, the wire pulley 54 reels the wire pulley, thereby pulling the slide bar 34 through the wire pulley, and the privacy curtain 31 translates outward.

[0101] It should be noted that, in the curtain device 100, a plurality of guide wheels 56 are provided, and the plurality of guide wheels 56 can be arranged according to the routing requirements of the cable, such as arranging the guide wheel 56 at the connecting inflection point of the first connecting rod 411 and the second connecting rod 412, arranging the guide wheel 56 at the connection position between the second connecting rod 412 and the lower shell 12 in the lower shell 12, etc., so as to realize the reversal of the routing direction of the cable through the guide wheel 56, so as to facilitate the guidance of the direction of the cable. Figure 14 and Figure 15 As shown, when the guide wheel 56 is arranged horizontally (ie, the axial direction of the guide wheel 56 is arranged vertically), the pull wire can better apply a driving force to the slide rod 34 parallel to its sliding direction relative to the lower shell 12.

[0102] like Figure 13 As shown, the driven gear 55 is coaxially arranged and connected to the wire wheel 54. The driven gear 55 can drive the wire wheel 54 to rotate synchronously to realize the winding and releasing action of the wire wheel 54 on the pulling line.

[0103] Furthermore, the driving gear 511 is arranged on the second driving screw 51, and the second driving screw 51 can drive the driving gear 511 to rotate synchronously, so that the driving gear 511 can be driven by the second driving motor 53, and the driving force can be further transmitted to the pulley 54 through the driven gear 55, which helps to improve the integration of the second driving device 5 in the upper shell 11 and save layout space.

[0104] It is understood that when the wire pulley 54 reels the wire, the wire can drive the slide bar 34 to translate outward, thereby adjusting the position of the lower end of the privacy curtain 31 in the Y direction; when the second sleeve 33 slides outward along the Y direction, the position of the upper end of the privacy curtain 31 in the Y direction can be adjusted. In other words, under the drive of the second drive device 5, the upper and lower ends of the privacy curtain 31 can be translated synchronously in the Y direction (outward or inward), which helps to improve the stability of the Y-direction position adjustment process of the privacy curtain 31.

[0105] Specifically, when the second drive motor 53 outputs a driving force to drive the second drive screw 51 to rotate, the drive gear 511 rotates synchronously with the second drive screw 51, so that the driving force can be transmitted to the pulley 54 through the cooperation of the drive gear 511 and the driven gear 55, thereby realizing the winding action of the pulley 54, so as to drive the slide rod 34 to drive the lower end of the privacy curtain 31 to translate outward, and the second drive screw 51 drives the second slide foot 52 to drive the second sleeve 33 to move outward along the Y direction, so as to drive the upper end of the privacy curtain 31 to translate outward through the second sleeve 33, thereby realizing the synchronous outward translation of the upper and lower ends of the privacy curtain 31.

[0106] It should be noted that the winding length of the wire pulley 54, the translation distance of the slide rod 34, and the translation distance of the second sleeve 33 driven by the second slide foot 52 can be correlated and matched, so that the privacy curtain 31 can perform translational actions at the upper and lower ends of the driving action of the second drive device 5 synchronously.

[0107] In some embodiments of the present application, the connection position between the pull wire and the slide rod 34 is preferably set near the inner end of the slide rod 34, so as to increase the sliding stroke of the slide rod 34 in the Y direction relative to the lower shell 12, and reduce the difficulty of arranging the slide rod 34 and the pull wire at the lower shell 12.

[0108] Combine Figure 10 and Figure 11 As shown, there are two groups of privacy curtain assemblies 3, and the two groups of privacy curtain assemblies 3 are arranged along the Y direction, so that the areas on both sides of the curtain 21 in the Y direction can be blocked by the two groups of privacy curtain assemblies 3 respectively, thereby fully improving the privacy protection effect on both sides of the curtain 21.

[0109] Further integration Figure 6As shown, the second drive device 5 also includes a return spring 57, which is connected between the two slide bars 34 in the two sets of privacy curtain assemblies 3, and the return spring 57 can store energy when the two slide bars 34 slide outward, so that the return spring 57 has a movement tendency to pull the two slide bars 34 inward to reset.

[0110] It can be understood that the slide rod 34 is pulled by the pull wire to move outward relative to the lower shell 12. During the outward movement of the slide rod 34, the slide rod 34 can pull the return spring 57 to store energy in the return spring 57, so that the return spring 57 has a movement tendency to pull the slide rod 34 back inward.

[0111] Specifically, when the second drive device 5 drives the second sleeve 33 to move inward (i.e., toward the side closer to the second drive motor 53), the upper end of the privacy curtain 31 translates inward, and the wire pulley 54 rotates in the opposite direction to release the pull wire. The slide bar 34 can translate inward under the tension of the return spring 57 to achieve reset adjustment of the privacy curtain 31 in the Y direction. At the same time, during the reset process of the privacy curtain 31, the upper and lower ends of the privacy curtain 31 can achieve synchronous translation to improve the stability of the reset process of the privacy curtain 31.

[0112] In a further embodiment of the present application, the second drive device 5 is provided with two sets of drive mechanisms corresponding to the two sets of privacy curtain assemblies 3 (such as: including the above-mentioned second drive screw 51, second slide foot 52, second drive motor 53, drive gear 511, wire pulley 54, driven gear 55 and guide wheel 56, etc.), and the two second drive screws 51 in the two sets of drive mechanisms can be driven by the same second drive motor 53, thereby being able to achieve synchronous driving of the two sets of drive mechanisms while reducing the number of drive motors set.

[0113] like Figure 12 As shown, in some embodiments of the present application, the curtain device 100 also includes a guide rod 35, which is arranged at the upper shell 11, and the guide rod 35 is arranged above the second drive device 5. The guide rod 35 is used to guide and cooperate with the privacy curtain 31, so that the privacy curtain 31 led out from the second sleeve 33 can pass over the second drive device 5 from the guide rod 35 to avoid the device arranged on the upper shell 11 (such as: the second drive device 5).

[0114] The curtain assembly 2 can be unfolded downward by pulling the curtain unfolding end 211 by the lower shell 12, without having to avoid the device arranged at the upper shell 11.

[0115] like Figure 6As shown, in some embodiments of the present application, when the privacy curtain 31 is in the unfolded state, the width of the privacy curtain 31 in the Y direction gradually increases from top to bottom, thereby facilitating the matching of the privacy curtain 31 with the shape of the inner wall of the passenger compartment, and the portion of the privacy curtain 31 that is wider than the second sleeve 33 can be wrapped around the first sleeve 32. It is understood that the shape and size of the privacy curtain 31 can be adaptively designed according to the contours of the passenger compartment so that the privacy curtain 31 can match the shape of the inner wall of the passenger compartment.

[0116] Combine Figure 10 and Figure 11 As shown, it can be understood that before the privacy curtain 31 moves outward along the Y direction, the privacy curtain 31 and the screen 21 are overlapped in the X direction, thereby facilitating the synchronous retraction and extension of the privacy curtain 31 and the screen 21.

[0117] like Figure 2 As shown, in some embodiments of the present application, the privacy curtain assembly 3 also includes a support rod 36, which extends along the Y direction. The support rod 36 is connected to the privacy curtain 31 and is used to support the privacy curtain 31 to improve the stability of the privacy curtain 31 in the unfolded state and will not cause interference when the privacy curtain 31 is rolled up.

[0118] Reference Figures 1-15 Describe the unfolding and using process of the curtain device 100 according to the embodiment of the present application:

[0119] First, the connecting rod 424 assembly is driven to unfold by the first driving device 4, so as to drive the lower shell 12 to move downward relative to the upper shell 11 through the connecting rod assembly 41. Driven by the lower shell 12, the curtain 21 and the privacy curtain 31 are synchronously unfolded downward.

[0120] Next, after the curtain 21 and the privacy curtain 31 are synchronously deployed, the second drive device 5 drives the second sleeve 33 to cause the upper end of the privacy curtain 31 to translate outward. The pull wire can then pull the slide bar 34 to cause the lower end of the privacy curtain 31 to translate synchronously, thereby achieving synchronous translation of the upper and lower ends of the privacy curtain 31 until the privacy curtain 31 is adjusted into position along the Y direction. Simultaneously, during this process, the return spring 57 accumulates energy.

[0121] It should be noted that the unfolding driving mode of the screen device 100 is opposite to the retracting driving mode.

[0122] The vehicle according to the embodiment of the present application includes the above-mentioned curtain device 100 .
