[0044] Vehicle-mounted ceiling screens typically flip up and down or move horizontally along the vehicle body to meet varying viewing distance requirements for passengers and vehicles. However, the mechanisms used in related art to drive these flipping and translational displays are complex and heavy, and are exposed to the outside of the display, affecting aesthetics. Therefore, there is a need for an improved vehicle-mounted ceiling screen and vehicle to address these issues. The following describes the embodiments of this specification in detail.

[0045] 1 and 4 , this embodiment provides a vehicle-mounted ceiling screen, which includes a mounting plate 10, a translation assembly 20, and a display assembly 30. The translation assembly 20 is arranged on the upper side of the mounting plate 10. The display assembly 30 includes a display 31, which is arranged on the lower side of the mounting plate 10. The translation assembly 20 drives the display assembly 30 to move, that is, to move along the length direction of the vehicle.

[0046] In this embodiment, the translation component 20 and the display screen 31 are respectively arranged on the upper and lower sides of the mounting plate 10, so that the translation component 20 is blocked by the display screen 31 and the mounting plate 10, thereby achieving the effect of the display screen 31 being suspended, and the overall ceiling screen occupies little space and is beautiful.

[0047] As shown in Figure 1, the display screen assembly 30 also includes a display screen connector 32, which is arranged on the sides of the translation assembly 20 and the display screen 31 and connects the translation assembly 20 and the display screen 31 respectively. Therefore, when the translation assembly 20 moves along the length direction of the vehicle, the display screen 31 in the display screen assembly 30 can be driven to move along the length direction of the vehicle through the display screen connector 32.

[0048] As shown in Figures 1 and 11 , the translation assembly 20 includes a movable rail 21, a fixed rail 22, and a first drive member 23. The fixed rail 22 is fixed to the upper side of the mounting plate 10. In some embodiments, the fixed rail 22 is integrally injection-molded with the mounting plate 10 to strengthen the connection between the mounting plate 10 and the fixed rail 22. The movable rail 21 is slidably connected to the fixed rail 22. The first drive member 23 is disposed on the upper side of the mounting plate 10 and drives the movable rail 21 to slide linearly relative to the fixed rail 22 along the length of the vehicle.

[0049] In some embodiments, the movable rail 21 is hollow or made of lightweight material, thereby reducing the power output of the first driving member 23 when driving the movable rail 21 to slide linearly along the length of the vehicle. Furthermore, the sliding length of the movable rail 21 is determined by combining its own length with the dimensions of the fixed rail 22 and mounting plate 10 along the length of the vehicle.

[0050] In the embodiments shown in Figures 1 and 11 , the top of the fixed rail 22 has an upwardly open groove-shaped structure, and the bottom of the movable rail 21 has a snap-fit ​​portion 213 that snaps into the groove-shaped structure. The maximum width of the snap-fit ​​portion 213 is greater than the maximum width of the top opening of the fixed rail 22, thereby restricting the movable rail 21 to sliding linearly within the groove-shaped structure along the length of the vehicle, preventing the fixed rail 22 and movable rail 21 from separating.

[0051] In addition to the aforementioned considerations regarding the possibility of the fixed rail 22 and movable rail 21 being disengaged, it is also necessary to be mindful of the possibility that the movable rail 21 could move vertically and horizontally, thereby pulling on the fixed rail 22 and affecting the stability of the connection between the fixed rail 22 and the mounting plate 10. In the embodiment shown in FIG1 , the outer walls of the engaging portion 213 abut against the inner walls of the grooved structure of the fixed rail 22, thereby limiting the vertical and horizontal movement of the engaging portion 213, and thus limiting the vertical and horizontal movement of the movable rail 21.

[0052] The weight of the movable guide rail 21 itself can also play a role in limiting the vertical movement of the movable guide rail 21. Flexible and / or elastic members can also be placed between the outer wall of the clamping portion 213 and the inner wall of the groove structure to further limit the vertical and horizontal movement of the clamping portion 213 and reduce the collision and extrusion force between the clamping portion 213 and the groove structure.

[0053] In addition to ensuring the stability of the movable guide rail 21 and the fixed guide rail 22 during linear sliding through the structural characteristics of the above-mentioned translation assembly 20 itself, this embodiment also provides a first driving member 23. Referring to Figures 11-13, the first driving member 23 includes a first motor 231, a winding wheel 232, and a cable 233. The outer wall of the winding wheel 232 is spirally arranged with a groove 2321. The middle part of the cable 233 is wound in the groove 2321 of the winding wheel 232, and the two ends of the cable 233 are arranged in opposite directions relative to the rotation direction of the winding wheel 232. The output shaft of the first motor 231 is coaxially arranged with the winding wheel 232. When the output shaft of the first motor 231 rotates, it drives the cable 233 to rotate forward or reverse around the winding wheel 232.

[0054] Specifically, the outer periphery of the output shaft of the first motor 231 is provided with external teeth 2311, and the inner wall of the winding wheel 232 is provided with internal teeth 2322 engaged with the external teeth 2311. When the first motor 231 drives the output shaft to rotate forward or reverse, it synchronously drives the winding wheel 232 to rotate forward or reverse, and finally drives the length of the two ends of the rope 233 on the winding wheel 232 to change, so as to realize the linear sliding of the movable guide rail 21.

[0055] In this embodiment, as shown in Figure 11 , the first driving member 23 further includes a first cable end fixing portion and a second cable end fixing portion. The first cable end fixing portion includes a first cable end fixing plate 236 and a first nail cap 237. The first cable end fixing plate 236 is fixed to the first end 211 of the movable guide rail 21, near one side of the first driving member 23. The first cable end fixing plate 236 is provided with a first notch 2361, and the first nail cap 237 is connected to the tail portion 2332 of the cable 233 and fixed in the first notch 2361.

[0056] The second cable end fixing portion includes a second cable end fixing plate 238 and a second nail cap (not shown). The second cable end fixing plate 238 is fixed to the second end 212 of the movable guide rail 21, near the side of the first driving member 23. That is, the first cable end fixing plate 236 and the second cable end fixing plate 238 are arranged on the same side. The second cable end fixing plate 238 has a second notch 2381, and the second nail cap is connected to the end 2331 of the cable 233 and fixed in the second notch 2381.

[0057] In some embodiments, to ensure the stability of the cable 233 during movement, reduce the tension of the cable 233, and enable smoother linear sliding of the movable guide rail 21 connected to the cable 233, as shown in FIG11 , the first driving member 23 further includes a first bracket 234 and a second bracket 235. The first bracket 234 is arranged on top of the mounting plate 10 and is located at the first end 211 of the movable guide rail 21, and the second bracket 235 is connected to the second end 212 of the movable guide rail 21. The end 2331 of the cable 233 passes through the first bracket 234 and is fixed to the second end 212 of the movable guide rail 21 via the second cable end fixing portion. The tail 2332 of the cable 233 passes through the second bracket 235 and is fixed to the first end 211 of the movable guide rail 21 via the first cable end fixing portion.

[0058] In order to avoid overlapping friction between the end 2331 of the cable 233 and the tail 2332 of the cable 233, the second bracket 235 is connected above the end 2331 of the cable 233, and the end 2331 of the cable 233 and the tail 2332 of the cable 233 are arranged up and down.

[0059] The following describes embodiments of the extension and contraction of the first driving member 23 .

[0060] The extension process of the first driving member 23: the first motor 231 drives the winding wheel 232 to rotate counterclockwise, at this time the tail 2332 of the cable 233 is released from the groove 2321 and extended, and at the same time the end 2331 of the cable 233 is contracted and rolled into the groove 2321. When the end 2331 of the cable 233 is contracted and rolled into the groove 2321, it drives the second cable end fixing part to move toward the direction close to the first bracket 234, thereby realizing the extension of the movable guide rail 21.

[0061] The contraction process of the first driving member 23: After the above-mentioned extension process is completed, when the vehicle-mounted ceiling screen needs to be retracted, the first motor 231 drives the winding wheel 232 to rotate clockwise. At this time, the end 2331 of the cable 233 is released from the groove 2321 and extended. At the same time, the tail 2332 of the cable 233 is contracted and rolled into the groove 2321. When the tail 2332 of the cable 233 is contracted and rolled into the groove 2321, it drives the first cable end fixing part to move toward the direction close to the first bracket 234, as shown in Figure 1. The movable guide rail 21 is contracted and the first cable end fixing part moves to the vicinity of the first bracket 234.

[0062] In this embodiment, referring to Figures 1 and 14-15, a mounting portion is provided on the upper side of the mounting plate 10, and the mounting portion includes a winding wheel base 13 and a winding wheel cover 14. The winding wheel base 13 is arranged on the upper side of the mounting plate 10, and the winding wheel cover 14 is snapped onto the winding wheel base 13 and forms a chamber for accommodating the first motor 231 and the winding wheel 232.

[0063] In some embodiments, the reel base 13 is integrally formed with the mounting plate 10. The reel cover 14 is fastened to the reel base 13 and secured thereto via screws, thereby limiting the position of the first motor 231 and the reel 232 within the chamber. To facilitate the extension of the cable 233 from the chamber, a wire groove 141 is provided on the reel cover 14, as shown in FIG14 , for the cable 233 to extend or retract.

[0064] Of course, the above is only an embodiment of driving the movable guide rail 21 to translate along the length direction of the vehicle. The present application is not limited to this. It can also be achieved by sliding the slider and the slide rail or chain transmission, etc. The specific translation structure of the movable guide rail 21 is not limited here.

[0065] In some embodiments, as shown in FIG1 , two translation assemblies 20 are provided and symmetrically arranged at both ends of the upper side of the mounting plate 10 to enhance the stability of the horizontal movement of the movable guide rail 21. Alternatively, a single translation assembly 20 may be provided. In some embodiments, when a single translation assembly 20 is provided, the translation assembly 20 is positioned in the middle of the top of the mounting plate 10. Furthermore, multiple translation assemblies 20 may be provided, such as three or four, depending on the size of the mounting plate 10. This is not a limitation.

[0066] Among them, the size of the display screen 31 along the width direction of the vehicle is greater than or equal to the size of the mounting plate 10 and the translation assembly 20 along the width direction of the vehicle. Therefore, the mounting plate 10 and the translation assembly 20 can be blocked by the display screen 31, so that the display screen 31 produces a feeling of floating movement during the linear sliding process, thereby improving the driving experience of the passengers.

[0067] The display screen 31 is connected to the movable rail 21 in the translation assembly 20. Specifically, when two translation assemblies 20 are provided, two display screen connectors 32 are provided, one connecting each of the two translation assemblies 20 and the other end of the display screen 31. In some embodiments, the display screen connector 32 is rotatably connected to the movable rail 21, thereby allowing the display screen 31, which is connected to the other end of the display screen connector 32, to be rotated and adjusted to meet the different viewing angles required by passengers.

[0068] In other embodiments, the other end of the display screen connector 32 is rotatably connected to the display screen 31, and the display screen 31 is driven to rotate through the display screen 31's own rotation structure or a rotation mechanism connected to the display screen 31, thereby adjusting the viewing angle between the display screen 31 and the occupant.

[0069] As shown in Figure 1, two sets of translation assemblies 20 are symmetrically arranged at either end of the top of the mounting plate 10. To reduce the weight and simplify the structure of the first driver 23, the first driver 23 is located at only one end of the mounting plate 10, i.e., only one set of first driver 23 is provided. However, considering the need to synchronously drive the movement of the other set of translation assemblies 20, the two display screen connectors 32 are connected to the same display screen 31. When the first driver 23 drives the movable guide rails 21 on one set of translation assemblies 20 to slide, the corresponding display screen connector 32 connected to the movable guide rail 21 moves synchronously, thereby driving the movement of the display screen 31 and ultimately the other set of translation assemblies 20 connected to the other end of the display screen 31.

[0070] In some embodiments, the vehicle-mounted ceiling screen also includes a connecting plate 24, which is arranged under the mounting plate 10 and connected to the movable guide rail 21; in this embodiment, the connecting plate 24 connects the two movable guide rails 21, and then when the movable guide rails 21 on one group of translation assemblies 20 slide, the movable guide rails 21 on the other group of translation assemblies 20 can be directly driven to slide through the connecting plate 24.

[0071] In some embodiments, as shown in FIG2 , the vehicle-mounted ceiling screen further includes a flip assembly 40 , which is disposed on the connecting plate 24 . The flip assembly 40 connects to the display screen 31 and causes the display screen 31 to flip up and down, thereby adjusting the viewing angle of the display screen for the occupants and improving the driving experience. FIG3-8 illustrate schematic diagrams of the display screen 31 in an open or closed state, when it moves to the front or rear end.

[0072] As shown in Figures 3 and 15 , the mounting plate 10 includes a bottom plate 15 and a top plate 16 located above the bottom plate. A first receiving space 17 is formed below the top plate 16, and a second receiving space 18 is formed above the bottom plate 15. In this embodiment, the bottom plate 15 and the top plate 16 are connected by vertically arranged plates and integrally formed to enhance the overall structural strength of the mounting plate 10. The bottom plate 15 and the top plate 16 may also be connected by plates of other structures, which are not limited here.

[0073] The first driving member 23 is disposed within the second receiving space 18, and the highest point of the first driving member 23 in the second receiving space 18 is no higher than the upper side of the top plate 16. The flip assembly 40 is partially located within the first receiving space 17, reducing leakage of the flip assembly 40 and improving the overall structure of the ceiling screen.

[0074] Specifically, as shown in Figure 2, the flip assembly 40 includes a connecting rod assembly 41 and a second driving member 42. One end of the connecting rod assembly 41 is fixedly connected to the display screen 31, and the other end of the connecting rod assembly 41 is hingedly connected to the second driving member 42. The second driving member 42 drives the connecting rod assembly 41 to move along the length of the vehicle, thereby driving the connecting rod assembly 41 to rotate, ultimately flipping the display screen 31 fixed to the connecting rod assembly 41.

[0075] In some embodiments, in order to improve the connection stability between the connecting rod assembly 41 and the display screen 31, the display screen assembly 30 also includes a display screen shaft 33, the display screen 31 is connected to the display screen shaft 33, the two ends of the display screen shaft 33 are respectively connected to the display screen connector 32, and one end of the connecting rod assembly 41 is fixedly connected to the middle part of the display screen shaft 33.

[0076] 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 fixedly connected to the display screen shaft 33. In some embodiments, one end of the first connecting rod 411 is fixedly connected to the middle portion of the display screen shaft 33; the other end of the first connecting rod 411 is hingedly connected to one end of the second connecting rod 412, and the other end of the second connecting rod 412 is hingedly connected to the second driving member 42.

[0077] Among them, the end of the connecting plate 24 near the display screen 31 is provided with a strip-shaped notch 241 for the rotation of the first connecting rod 411 and the second connecting rod 412, as shown in Figure 1. In this embodiment, as shown in Figure 4, when the second connecting rod 412 abuts within the strip-shaped notch 241, the second connecting rod 412 cannot continue to rotate downward due to the length limitation of the strip-shaped notch 241. At this time, the hinge point of the first connecting rod 411 and the second connecting rod 412 is located above the line connecting the center point of the connection between the first connecting rod 411 and the display screen 31 and the center point of the connection between the second connecting rod 412 and the second driving member 42. The advantage of this design is that it facilitates the first connecting rod 411 and the second connecting rod 412 to drive the display screen 31 to rotate in the opposite direction along the original rotation path to the closed state.

[0078] In this embodiment, the sliding distance of the slider 421 of the second driving member 42 and the length of the first connecting rod 411 and the second connecting rod 412 further limit the first connecting rod 411 from driving the second connecting rod 412 to continue to rotate toward the lower end in the original rotation direction, causing the display screen 31 to flip over to the lower end and then continue to flip over upward in the original rotation direction, resulting in the inability to rotate to the closed state.

[0079] In addition, the second driving member 42 includes a slider 421, a second motor 422 and a screw rod 423. The other end of the second connecting rod 412 is hinged to the slider 421. The second motor 422 drives the slider 421 to move linearly on the screw rod 423, thereby driving the rotation of the second connecting rod 412.

[0080] In some embodiments, as shown in FIG1 , the vehicle-mounted ceiling screen further includes a ceiling screen fixture 12 for connecting to the vehicle roof. The ceiling screen fixture 12 is fixed to the upper side of the roof panel 16, i.e., the upper side of the mounting plate 10. The dimension of the display screen 31 along the vehicle width direction is greater than or equal to the dimension of the ceiling screen fixture 12 along the vehicle width direction. Thus, the ceiling screen fixture 12 can also be obscured by the display screen 31, thereby achieving the effect of a suspended display screen 31. Specifically, in some embodiments, a rubber coating layer is provided around the top of the ceiling screen fixture 12, and the fixture is bonded to the sunroof glass or roof panel metal by applying glue to the rubber coating layer.

[0081] Furthermore, as shown in FIG15 , the mounting plate 10 is provided with a ceiling screen mounting hole 11, and the bottom portion of the ceiling screen fixing member 12 is removably mounted to the ceiling screen mounting hole 11, for example, by means of a bolt and nut. It should be noted that the ceiling screen fixing member 12 and the first driving member 23 are staggered to minimize contact between the ceiling screen fixing member 12 and the first driving member 23, thereby reducing the impact on the driving effect of the first driving member 23 or the fixing effect of the ceiling screen fixing member 12 on the vehicle roof.

[0082] In some embodiments, as shown in FIG10 , the vehicle-mounted ceiling screen further includes a curtain retracting assembly 50, which includes a retracting mechanism 51 and a curtain 52. The retracting mechanism 51 is connected to the lower end of the display screen 31. One end of the curtain 52 is connected to the mounting plate 10 or the connecting plate 24, and the other end is wound within the retracting mechanism 51. When the display screen 31 flips downward, the retracting mechanism 51 is simultaneously driven downward, and the curtain 52 within the retracting mechanism 51 is pulled out. Simultaneously, in conjunction with projection equipment, the display screen 31 and the curtain 52 can be viewed from both sides, allowing passengers in two rows to watch the screen simultaneously.

[0083] In some embodiments, as shown in Figure 9, the vehicle-mounted ceiling screen also includes a lighting assembly 60, including but not limited to a ceiling lamp. The lighting assembly 60 is installed on the lower side of the mounting plate 10. When the display screen 31 is driven by the movable guide rail 21 to slide along the fixed guide rail 22, the lighting assembly 60 is gradually exposed as the display screen 31 moves.

[0084] Corresponding to the aforementioned embodiment of the vehicle-mounted ceiling screen, this specification also provides an embodiment of a vehicle using the vehicle-mounted ceiling screen. By bonding the above-mentioned vehicle-mounted ceiling screen to the vehicle's sunroof glass or roof sheet metal, the requirements of different passengers' human-machine visibility can be met, thereby improving the passengers' driving experience.
