Description

Technical Field

[0001] This invention relates to the field of vehicles, and more particularly to a curtain device for vehicles and a vehicle. Background Technology

[0002] Currently, some vehicle models incorporate features to enhance user experience, such as projecting images onto a screen within the passenger compartment. This allows occupants to view the displayed images, improving their overall riding experience. The screen is typically located behind the driver and front passenger seats and is used to project images to rear passengers.

[0003] In related technologies, the screen is usually placed in the middle area of ​​the vehicle in the Y direction, which results in gaps between the screen and the side walls of the passenger compartment on both sides of the Y direction. Light from the front of the vehicle can shine through the gaps into the rear area (i.e., the viewing area where the passengers are located), which will make the areas on both sides of the screen brighter and affect the viewing effect of the image on the screen. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a curtain device for vehicles that has a good shading effect and can improve the privacy protection effect of the curtain device in use.

[0006] The lower housing is adapted to drive the curtain and privacy curtain to unfold synchronously, and the second driving device is adapted to drive the privacy curtain to translate along the Y direction when the privacy curtain is in the unfolded state, so that the privacy curtain covers the gap between the curtain and the side wall of the passenger compartment.

[0007] According to the embodiments of this application, the screen device drives the lower housing to move relative to the upper housing through a first driving device to realize the opening and closing of the screen and privacy curtain. When the privacy curtain is in the unfolded state, the privacy curtain can be driven to translate along the Y direction through a second driving device to adjust the lateral position of the privacy curtain relative to the screen. The privacy curtain is arranged in a position that can block the gap between the screen and the side wall of the passenger compartment, which helps to improve the separation effect of the screen device on the front and rear space of the passenger compartment, can ensure the privacy needs of the rear passengers, and can improve the viewing experience of the rear passengers on the screen.

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

[0043] The following is for reference. Figures 1-15 A curtain device 100 for a vehicle according to an embodiment of the present invention is described.

[0044] The screen device 100 is installed 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 a projector and other equipment with projection function) can project the image onto the projection area formed by the screen device 100 to present the image to the occupants in the passenger compartment, so as to meet the user's needs for viewing images in the passenger compartment, such as watching movies or PPT (PowerPoint) slides.

[0045] The curtain device 100 according to the embodiments of this application includes: a shell assembly 1, a curtain 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 has a curtain 21 rolled up 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 has a privacy curtain 31 rolled up 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 driving device 4 is mounted on the shell assembly 1 and is used to drive the lower shell 12 to move vertically up and down relative to the upper shell 11. This causes the lower shell 12 to drive the unfolding ends of the curtain 211 and the privacy curtain 31 to move downwards, so as to pull the curtain 21 and the privacy curtain 31 down and unfold synchronously. Thus, the synchronous unfolding of the curtain 21 and the privacy curtain 31 is achieved through the driving cooperation between the first driving device 4 and the shell assembly 1.

[0048] Furthermore, the second drive device 5 is mounted on the housing 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 screen 21 in the Y direction, so as to adjust the privacy curtain 31 to a suitable area to block the gap between the screen 21 and the passenger compartment, thereby improving the privacy protection effect after the screen device 100 is unfolded, and preventing light from passing through the gap between the screen device 100 and the side wall of the passenger compartment and affecting the projection display effect on the screen 21.

[0049] The "Y-direction" of a vehicle refers to its left and right directions.

[0050] Understandably, some vehicle models currently incorporate features to enrich user experience, such as projecting images onto a screen 21 within the passenger compartment. This allows occupants to view the images displayed on the screen, enhancing their overall riding experience. The screen 21 is typically positioned behind the driver and front passenger seats to project images to rear passengers. Furthermore, when unfolded, the screen 21 is usually positioned parallel to the YZ plane, facilitating rear passengers' viewing of the images from rear to front.

[0051] In related technologies, the screen 21 is usually placed in the middle area of ​​the vehicle in the Y direction, which results in gaps between the screen 21 and the side walls of the passenger compartment on both sides in the Y direction. Light from the front of the vehicle can shine through the gaps into the rear area (i.e., the viewing area where the passengers are located) and affect the viewing effect of the image on the screen 21.

[0052] Understandably, if light from the front of the vehicle shines through the gaps into the rear passenger compartment, the areas on both sides of the screen 21 in the Y direction will be brighter, thus affecting the viewing experience of the rear passengers on the image displayed on the screen 21 in front of them.

[0053] In the screen device 100 of this 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 display images. The privacy curtain 31 in the privacy curtain assembly 3 is adapted to move to the gap between the screen 21 and the passenger compartment after being unfolded, so as to block the gap between the screen 21 and the passenger compartment in the Y direction. Thus, the front and rear rows of the vehicle can be separated by the screen 21 and the privacy curtain 31, providing a private environment suitable for business negotiations, watching movies and working for the rear passenger, and improving the privacy protection effect of the screen device 100.

[0054] The lower housing 12 can drive the curtain 21 and 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 unfolded, 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] Combination Figure 1 and Figure 2 As shown, the privacy curtain 31 is positioned on the side of the screen 21 away from the projection surface, thereby exposing the projection area of ​​the screen 21 to the rear and preventing the privacy curtain 31 from blocking the projection area formed on the screen 21, thus ensuring the viewing experience of the occupants.

[0056] like Figure 10 As shown, the lower housing 12 moves downward relative to the upper housing 11, and the lower housing 12 can move the curtain 21 and the privacy curtain 31. Figure 10 (Not shown in the image) unfolds synchronously, thus fully presenting the screen 21 in front of the rear passengers, facilitating their viewing of the images displayed on the screen 21; such as Figure 11 As shown, the privacy curtain 31 extends from the front side of the screen 21 (i.e., the side 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. This prevents light from shining through the gap between the screen 21 and the passenger compartment to the rear, while providing a more private space for the rear passengers, thus improving the riding and movie-watching experience of the rear passengers.

[0057] It is understandable that in the curtain assembly 2, the curtain assembly 2 has a first roll-up section for rolling up the curtain 21. When the lower housing 12 moves downward relative to the upper housing 11, the lower housing 12 pulls out the curtain 21 by pulling the curtain unfolding end 211. And when the lower housing 12 moves upward relative to the upper housing 11, the first roll-up section can synchronously roll up the curtain 21 along with the upward movement of the lower housing 12, thereby realizing the rolling up and unrolling of the curtain 21. Similarly, the privacy curtain assembly 3 can also realize the rolling up and unrolling of the privacy curtain 31 by setting a second roll-up section, which is the same as the curtain 21 rolling up and unrolling method described above.

[0058] According to the embodiments of this application, the screen device 100 drives the lower housing 12 to move relative to the upper housing 11 through the first driving device 4, so as to realize the opening and closing of the screen 21 and the privacy curtain 31. When the privacy curtain 31 is in the unfolded state, the privacy curtain 31 can be driven to translate along the Y direction through the second driving device 5 to adjust the lateral position of the privacy curtain 31 relative to the screen 21. The privacy curtain 31 is arranged in a position that 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 space of the passenger compartment, can ensure the privacy needs of the rear passengers, and can improve the viewing experience of the rear passengers on the screen 21.

[0059] Combination Figure 4 and Figure 5 As shown, in some embodiments of this application, the first driving device 4 includes a linkage assembly 41 and a first driving part 42.

[0060] The linkage assembly 41 includes a first linkage 411 and a second linkage 412. One end of the first linkage 411 is rotatably connected to the upper housing 11, and one end of the second linkage 412 is connected to the lower housing 12. The other ends of the first linkage 411 and the second linkage 412 are rotatably connected to each other to form a linkage mechanism between the upper housing 11 and the lower housing 12.

[0061] It should be noted that the second link 412 is also rotatably connected to the lower housing 12, and the rotation axes of the first link 411 relative to the upper housing 11, the rotation axes of the lower housing 12 relative to the lower housing 12, and the rotation axes of the first link 411 relative to the second link 412 are arranged parallel to each other, so that the first link 411 and the second link 412 can be folded or unfolded in the same plane.

[0062] Furthermore, the first drive unit 42 is disposed on the upper housing 11 and is connected to the first connecting rod 411. The first drive unit 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 housing 12 to move through the second connecting rod 412, thereby realizing the position adjustment of the lower housing 12 relative to the upper housing 11.

[0063] Combination 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-shape faces the side wall of the passenger compartment, so that when the first link 411 and the second link 412 are folded together, they can be retracted inward (towards the central axis of the vehicle), thus avoiding the link assembly 41 from occupying too much external space and affecting the storage of the curtain device 100.

[0064] Specifically, when the first drive unit 42 drives the first connecting rod 411 to swing downward relative to the upper housing 11, the angle between the first connecting rod 411 and the second connecting rod 412 forming a 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 housing 12 relative to the upper housing 11, thereby enabling the curtain 21 and privacy curtain 31 to be simultaneously unfolded downward through the lower housing 12; when the first drive unit 42 drives the first connecting rod 411 to swing upward relative to the upper housing 11, the angle between the first connecting rod 411 and the second connecting rod 412 forming a 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 housing 12 relative to the upper housing 11, thereby enabling the curtain 21 and privacy curtain 31 to be simultaneously rolled up, and facilitating the storage of the connecting rod assembly 41 at the curtain device 100.

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

[0066] The first drive screw 421 is threadedly engaged with the first sliding foot 422. The first drive motor 423 is mounted on the upper housing 11 and is configured to drive the first drive screw 421 to rotate, thereby driving the first sliding foot 422 to translate along the Y-direction of the vehicle. This allows the first sliding foot 422 to output a driving force (such as tension or thrust) in the Y-direction. Simultaneously, the two ends of the drive link 424 are rotatably connected to the first sliding foot 422 and the first link 411, respectively. The drive link 424 drives the first link 411 to swing, transmitting the driving force to the first link 411 and achieving the swing drive of the first link 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 sliding foot 422, and the drive link 424 can restrict the rotation of the first sliding foot 422. Thus, the first sliding foot 422 can be moved in the Y direction by the first drive motor 423, so as to output the driving force in the Y direction through the first sliding foot 422.

[0068] Furthermore, the first sliding foot 422 can drive the drive link 424 to move. The drive 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 drive link 424. The drive link 424 drives the first link 411 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 this application, the first drive motor 423 is located at the middle position of the upper housing 11 in the Y direction. When the drive motor drives the first sliding foot 422 to move outward in the Y direction, the first sliding foot 422 drives the drive link 424 to drive the first link 411 to swing downward relative to the upper housing 11, so as to drive the first link 411 and the second link 412 to unfold. When the drive motor drives the first sliding foot 422 to move inward in the Y direction (i.e., closer to the side of the first drive motor 423), the first sliding foot 422 drives the drive link 424 to drive the first link 411 to swing upward relative to the upper housing 11, so as to drive the first link 411 and the second link 412 to fold.

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

[0071] Combination Figure 4 and Figure 5 As shown, in some embodiments of this application, the first driving device 4 includes two sets of linkage assemblies 41, and the first driving part 42 is provided with two sets of first driving screws 421, first sliding feet 422 and driving connecting rods 424 respectively connected and cooperating with the two sets of linkage assemblies 41. Moreover, the first driving part 42 can drive the two sets of linkage assemblies 41 to move synchronously, so as to realize the synchronous unfolding or folding of the two sets of linkage assemblies 41, thereby improving the stability of the lower housing 12 relative to the upper housing 11 during movement.

[0072] Reference Figure 4As shown, when the first drive device 4 is provided with two sets of connecting rod assemblies 41, the two sets of connecting rod assemblies 41 are respectively connected between the upper housing 11 and the lower housing 12. Thus, the lower housing 12 can be driven to move relative to the upper housing 11 by the synchronous unfolding or folding of the two sets of connecting rod assemblies 41, which helps to improve the stability of the movement process of the lower housing 12 relative to the upper housing 11.

[0073] In the two sets of linkage assemblies 41, the connection positions of the two first linkages 411 and the upper housing 11 are arranged at intervals along the Y direction, and the connection positions of the two second linkages 412 and the lower housing 12 are arranged at intervals along the Y direction, so that the connection positions of the two sets of linkage assemblies 41 and the housing assembly 1 are arranged at four points.

[0074] Preferably, the two sets of connecting rod assemblies 41 are symmetrically arranged on both sides of the first drive motor 423 to improve the stability of the lower housing 12 when subjected to driving force, so that the lower housing 12 remains stable during movement relative to the upper housing 11 and avoids deflection. At the same time, the two sets of first drive screws 421, first sliding feet 422, and drive connecting rods 424 are also symmetrically arranged on both sides of the first drive motor 423.

[0075] In a further embodiment of this application, the first drive motor 423 is configured to drive two first drive screws 421 to move simultaneously, thereby achieving synchronous driving of two sets of drive components (each set of drive components includes a first drive screw 421, a first sliding foot 422, and a drive connecting rod 424) with only one drive motor (i.e., the first drive motor 423), which helps to improve the compactness of the arrangement of various devices in the upper housing 11 and avoids wasting space.

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

[0077] The first sleeve 32 is mounted on the upper housing 11, and the second sleeve 33 is mounted on the first sleeve 32. The second sleeve 33 is connected to one end of the privacy curtain 31 and is connected to the second drive device 5. The second drive device 5 can drive the second sleeve 33 to slide relative to the first sleeve 32 in the Y direction, and the second sleeve 33 can rotate synchronously with the first sleeve 32 to roll up or unroll 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 relative to the first sleeve 32 in the Y direction, so as to drive the privacy curtain 31 to move synchronously in the Y direction, 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 relative to the first sleeve 32 in the Y direction, 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 relative to the first sleeve 32 in the Y direction, 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 rolling up of the privacy curtain 31.

[0080] Understandably, the second sleeve 33 rotates synchronously with the first sleeve 32, thus requiring the first sleeve 32 to be rotatably mounted on the upper housing 11 to meet the rotational requirements of both the first sleeve 32 and the second sleeve 33. Simultaneously, a privacy curtain 31 is connected to the second sleeve 33, allowing the privacy curtain 31 to be rolled up during the rotation of the second sleeve 33.

[0081] It should be noted that the privacy curtain 31's unfolding end 311 is connected to the lower housing 12, and the other end of the privacy curtain 31 is fixedly connected to the second sleeve 33. When the lower housing 12 moves downward relative to the upper housing 11, the lower housing 12 can drive the privacy curtain unfolding end 311 to move downward, so as to unfold the privacy curtain 31. Under the pull of the privacy curtain 31, the second sleeve 33 drives the first sleeve 32 to rotate synchronously to unroll the privacy curtain 31. At this time, the second winding part in the privacy curtain assembly 3 stores energy. When the lower housing 12 moves upward relative to the upper housing 11, the lower housing 12 can drive the privacy curtain unfolding end 311 to move upward. At this time, the second winding part releases energy and drives the first sleeve 32 and the second sleeve 33 to rotate, so as to roll up and wrap the privacy curtain 31 around the first sleeve 32 and the second sleeve 33, thereby realizing the winding up of the privacy curtain 31.

[0082] The “first winding section” and “second winding section” mentioned above can both be constructed as energy storage components such as torsion springs and leaf springs. The structure and arrangement of the first winding section and the second winding section are not specifically limited here. As long as they can drive the winding structure (such as the first sleeve 32 and the second sleeve 33 mentioned above) to realize the winding function.

[0083] Reference Figure 12 As shown, in some embodiments of this application, the outer peripheral wall of the first sleeve 32 is formed with a rib 321, which protrudes towards the second sleeve 33 along the radial direction of the first sleeve 32. The inner peripheral wall of the second sleeve 33 is formed with a groove that mates with the rib 321. At least part of the rib 321 extends into the groove to limit the second sleeve 33 relative to the first sleeve 32 in the circumferential direction, 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 this 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, multiple grooves are also formed on the inner circumferential wall of the second sleeve 33 to improve the circumferential limiting effect of the first sleeve 32 and the second sleeve 33.

[0085] like Figure 12 As shown, in some embodiments of this 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, thereby improving 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 parallel to the Y-direction of the vehicle.

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

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

[0089] Understandably, the second sliding foot 52 has a threaded hole that engages with the second drive screw 51. When the second motor drives the second drive screw 51 to rotate, the second drive screw 51 engages with the second sliding foot 52 to drive the second sliding foot 52 to move along the axial direction (i.e., the Y direction) of the second drive screw 51. The second sliding foot 52 can drive the second sleeve 33 to move synchronously, so as to realize the 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 this application, the upper housing 11 is provided with a guide groove 111 extending in the Y direction, and the second sliding foot 52 is provided with a guide protrusion 521. The guide protrusion 521 extends into the guide groove 111, and the guide groove 111 can guide and cooperate with the guide protrusion 521 to assist the second sliding foot 52 in translating relative to the upper housing 11 in the Y direction.

[0091] In some embodiments of this application, the outer wall surface of the second sleeve 33 is provided with a flange 331, the flange 331 protrudes along the radial direction of the second sleeve 33, and the second sliding foot 52 is provided with a clamping groove 522, the clamping groove 522 and the flange 331 are clamped and engaged in the Y direction, so that the second sliding 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. The flange 331 can also 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 this application, the clamping groove 522 extends along the circumferential direction of the second sleeve 33. The clamping groove 522 is U-shaped, allowing the second sleeve 33 to extend through the opening of the U-shaped structure to embed the flange 331 within the clamping groove 522, thereby achieving a clamping engagement between the second sliding foot 52 and the second sleeve 33. Furthermore, the installation and engagement method between the second sleeve 33 and the second sliding foot 52 is simple.

[0094] Combination Figure 7 and Figure 8 As shown, in some embodiments of this application, the lower housing 12 is provided with a sliding groove 121 extending in the Y direction, and the privacy curtain assembly 3 also includes a sliding rod 34, which is connected to the other end of the privacy curtain 31 (i.e., the privacy curtain unfolding end 311 mentioned above), and the sliding rod 34 can slide in cooperation with the sliding groove 121.

[0095] Combination 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 unfold downwards synchronously. After the curtain 21 and the privacy curtain 31 are unfolded into position, the privacy curtain 31 is driven to move horizontally in the Y direction by the second drive device 5, so as to adjust part of the privacy curtain 31 to be suitable for both sides of the curtain 21 in the Y direction.

[0096] The upper end of the privacy curtain 31 (i.e. 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 (i.e. the unfolded end 311 of the privacy curtain) can slide relative to the lower housing 12 in the Y-direction under the action of the slide rod 34, thereby realizing the overall translation of the privacy curtain 31 in the Y-direction and preventing wrinkles from forming at the privacy curtain 31.

[0097] Understandably, the privacy curtain unfolding end 311 is slidably mounted on the lower housing 12 via the slide bar 34, which can reduce the difficulty of adjusting the position of the privacy curtain unfolding end 311 and make the position adjustment of the privacy curtain 31 in the Y direction smooth.

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

[0099] Reference Figure 13 As shown, a pull line (not shown) is wound on the reel 54. The reel 54 is used to wind or release the pull line, and the pull line is connected to the slide bar 34 so that the slide bar 34 can slide on the lower housing 12 by pulling the pull line, thereby realizing the position adjustment of the slide bar 34 on the lower housing 12.

[0100] Furthermore, the driven gear 55 is poweredly connected to the drive gear 511, and the driven gear 55 drives the reel 54 to rotate, thereby enabling the reel 54 to wind and release the pull cord. The guide wheel 56 is mounted on the linkage assembly 41 and guides the pull cord, allowing it to slide smoothly. Specifically, when the second drive device 5 drives the second sleeve 33 to translate outwards, the reel 54 winds up the pull cord, thereby pulling the slide bar 34 and translating the privacy curtain 31 outwards.

[0101] It should be noted that multiple guide wheels 56 are provided in the curtain device 100. These guide wheels 56 can be arranged according to the routing requirements of the cable, such as placing the guide wheels 56 at the junction of the first link 411 and the second link 412, or placing the guide wheels 56 in the lower housing 12 near the connection point between the second link 412 and the lower housing 12. This allows for changing the routing direction of the cable through the guide wheels 56, facilitating the guidance of the cable's path. (Refer to...) Figure 14 and Figure 15 As shown, when the guide wheel 56 is arranged laterally (i.e., the axial direction of the guide wheel 56 is arranged vertically), the pull cable can better apply a driving force to the slide bar 34 in a direction parallel to its sliding direction relative to the lower housing 12.

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

[0103] Furthermore, the drive gear 511 is mounted on the second drive screw 51. The second drive screw 51 can drive the drive gear 511 to rotate synchronously, thereby driving the drive gear 511 through the second drive motor 53, and further transmitting the driving force to the pulley 54 through the driven gear 55. This helps to improve the integration of the second drive device 5 in the upper housing 11 and saves layout space.

[0104] Understandably, when the reel 54 winds up the pull cord, the pull cord can drive the slide bar 34 to move 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 in 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 move synchronously in the Y direction (outward or inward), which helps to improve the stability of the privacy curtain 31's Y-direction position adjustment process.

[0105] Specifically, when the second drive motor 53 outputs driving force to drive the second drive screw 51 to rotate, the drive gear 511 rotates synchronously with the second drive screw 51. Thus, the driving force can be transmitted to the spool 54 through the cooperation of the drive gear 511 and the driven gear 55, realizing the winding action of the spool 54. This drives the slide bar 34 to move the lower end of the privacy curtain 31 outward. Furthermore, the second drive screw 51 drives the second slide foot 52 to move the second sleeve 33 outward in the Y direction. This causes the upper end of the privacy curtain 31 to move outward through the second sleeve 33, thereby enabling the upper and lower ends of the privacy curtain 31 to move outward synchronously.

[0106] It should be noted that the winding length of the pull cord by the spool 54, the translation distance of the slide bar 34, and the translation distance of the second slide foot 52 driving the second sleeve 33 can be matched and matched so that the privacy curtain 31 can perform translational movements at the upper and lower ends under the driving action of the second drive device 5.

[0107] In some embodiments of this application, the connection position of the pull wire and the slide bar 34 is preferably located near the inner end of the slide bar 34, which can increase the sliding stroke of the slide bar 34 relative to the lower housing 12 in the Y direction and reduce the difficulty of arranging the slide bar 34 and the pull wire at the lower housing 12.

[0108] Combination Figure 10 and Figure 11 As shown, there are two sets of privacy curtain components 3, which are arranged along the Y direction. This allows the curtain 21 to be covered on both sides of the Y direction by the two sets of privacy curtain components 3, thus 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 two slide rods 34 in the two sets of privacy curtain assemblies 3. The return spring 57 can store energy when the two slide rods 34 slide outward, so that the return spring 57 has a tendency to pull the two slide rods 34 inward to reset.

[0110] Understandably, the slide bar 34 is pulled outward relative to the lower housing 12 by a pull wire. During the outward movement of the slide bar 34, the slide bar 34 can pull the return spring 57 to store energy, so that the return spring 57 has a tendency to pull the slide bar 34 back inward.

[0111] Specifically, when the second drive device 5 drives the second sleeve 33 to move inward (i.e., to the side closer to the second drive motor 53), the upper end of the privacy curtain 31 translates inward, and the pulley 54 rotates in the opposite direction to release the pull cord. The slide bar 34 can translate inward under the pulling force of the return spring 57 to achieve the 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 be synchronously translated to improve the stability of the reset process.

[0112] In a further embodiment of this application, the second driving device 5 is provided with two sets of driving mechanisms (such as the second driving screw 51, the second sliding foot 52, the second driving motor 53, the driving gear 511, the spool 54, the driven gear 55, and the guide wheel 56, etc.) corresponding to the two sets of privacy curtain components 3. The two second driving screws 51 in the two sets of driving mechanisms can be driven by the same second driving motor 53, thereby reducing the number of driving motors while realizing the synchronous driving of the two sets of driving mechanisms.

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

[0114] The curtain assembly 2 can be pulled downward by the lower housing 12 to unfold the curtain unfolding end 211, without having to avoid the device arranged on the upper housing 11.

[0115] like Figure 6As shown, in some embodiments of this 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. Furthermore, the portion of the privacy curtain 31 whose width is greater than that of the second sleeve 33 can be wrapped around the first sleeve 32. It is understood that the shape and dimensions of the privacy curtain 31 can be adaptively designed according to the contour of the passenger compartment to ensure that the privacy curtain 31 can match the shape of the inner wall of the passenger compartment.

[0116] Combination 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 curtain 21 are overlapped in the X direction, so as to facilitate the synchronous opening and closing of the privacy curtain 31 and the curtain 21.

[0117] like Figure 2 As shown, in some embodiments of this application, the privacy curtain assembly 3 further includes a support rod 36, which extends along the Y direction and is connected to the privacy curtain 31 to support the privacy curtain 31, thereby improving the stability of the privacy curtain 31 in the unfolded state and preventing interference when the privacy curtain 31 is rolled up.

[0118] Reference Figures 1-15 Describe the unfolding and use process of the curtain device 100 according to the embodiments of this application:

[0119] First, the first driving device 4 drives the connecting rod 424 assembly to unfold, so that the connecting rod assembly 41 drives the lower housing 12 to move downward relative to the upper housing 11. Under the drive of the lower housing 12, the curtain 21 and the privacy curtain 31 unfold downward synchronously.

[0120] Secondly, after the curtain 21 and privacy curtain 31 are simultaneously deployed, the second drive device 5 drives the second sleeve 33 to move the upper end of the privacy curtain 31 outward. Furthermore, the lower end of the privacy curtain 31 can be moved synchronously by pulling the slide bar 34 with a pull cable, thus achieving synchronous translation of the upper and lower ends of the privacy curtain 31 until it is adjusted into position along the Y direction. Simultaneously, the return spring 57 stores energy during this process.

[0121] It should be noted that the unfolding drive of the curtain device 100 is the opposite of the rewinding drive.

[0122] The vehicle according to an embodiment of this application includes the curtain device 100 described above.
