[0054] Next, the embodiments of this specification will be described in detail.

[0055] Referring to Figure 1 and Figure 4 As shown, this embodiment provides an in - vehicle ceiling screen. The in - vehicle ceiling screen includes a mounting plate 10, a translation component 20, and a display screen component 30. The translation component 20 is arranged on the upper side of the mounting plate 10, and the display screen component 30 includes a display screen 31. The display screen 31 is arranged on the lower side of the mounting plate 10. The translation component 20 drives the display screen component 30 to move, that is, to move along the length direction of the vehicle.

[0056] 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, achieving the effect of the display screen 31 floating, and the overall ceiling-mounted screen occupies a small space and is beautiful.

[0057] Specifically:

[0058] Referring to Figure 1 As shown, the display screen assembly 30 further includes a display screen connecting piece 32. The display screen connecting piece 32 is arranged on the sides of the translation component 20 and the display screen 31 and respectively connects the translation component 20 and the display screen 31. Then, when the translation component 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 connecting piece 32.

[0059] Referring to Figure 11 As shown, the translation component 20 includes a movable guide rail 21, a fixed guide rail 22 and a first driving member 23. The fixed guide rail 22 is fixed on the upper side of the mounting plate 10. Optionally, the fixed guide rail 22 and the mounting plate 10 are integrally injection-molded to enhance the connection strength between the mounting plate 10 and the fixed guide rail 22. The movable guide rail 21 is slidably connected to the fixed guide rail 22; the first driving member 23 is arranged on the upper side of the mounting plate 10 and drives the movable guide rail 21 to linearly slide relative to the fixed guide rail 22 along the length direction of the vehicle.

[0060] In a possible implementation manner, the movable guide rail 21 is of a hollow structure or made of a lightweight material, thereby reducing the output power when the first driving member 23 drives the movable guide rail 21 to linearly slide along the length direction of the vehicle. In addition, the sliding length of the movable guide rail 21 needs to be determined in combination with its own length and the dimensions of the fixed guide rail 22 and the mounting plate 10 along the length direction of the vehicle.

[0061] Among them, in the embodiments shown in Figure 1 and Figure 11 as shown, the top of the fixed guide rail 22 has a groove-shaped structure with an upward opening, and correspondingly, the bottom of the movable guide rail 21 has a clamping portion 213 clamped in the groove-shaped structure. The maximum width of the clamping portion 213 is greater than the maximum width of the opening at the top of the fixed guide rail 22, so that the movable guide rail 21 can only linearly slide in the groove-shaped structure along the length direction of the vehicle, avoiding the separation of the fixed guide rail 22 and the movable guide rail 21.

[0062] In addition to the above consideration of the separation of the fixed guide rail 22 and the movable guide rail 21, it is also necessary to pay attention to the crosstalk of the movable guide rail 21 in the vertical and horizontal directions, thereby pulling the fixed guide rail 22 and affecting the connection stability between the fixed guide rail 22 and the mounting plate 10. As Figure 1In the illustrated embodiment, the outer walls of the clamping portions 213 are respectively abutted against the inner walls of the groove-shaped structure, thereby restricting the displacement of the clamping portions 213 in the vertical and horizontal directions, that is, restricting the displacement of the movable guide rail 21 in the vertical and horizontal directions.

[0063] Of course, the gravity of the movable guide rail 21 itself can also play a role in restricting the displacement of the movable guide rail 21 in the vertical direction. Flexible members and / or elastic members, etc. can also be placed between the outer wall of the clamping portion 213 and the inner wall of the groove-shaped structure to further restrict the displacement of the clamping portion 213 in the vertical and horizontal directions, and at the same time, the collision and extrusion force between the clamping portion 213 and the groove-shaped structure can be reduced.

[0064] In addition to ensuring the stability of the linear sliding of the movable guide rail 21 and the fixed guide rail 22 through the structural characteristics of the translation assembly 20 itself, the present embodiment further provides a first driving member 23. Refer to Figures 11 - 13 As shown, the first driving member 23 includes a first motor 231, a wire winding wheel 232, and a cable 233. A groove 2321 is spirally arranged circumferentially on the outer wall of the wire winding wheel 232. The middle part of the cable 233 is wound in the groove 2321 of the wire winding wheel 232, and the two ends of the cable 233 rotate in opposite directions relative to the rotation direction of the wire winding wheel 232. The output shaft of the first motor 231 is coaxially arranged with the wire winding wheel 232. When the output shaft rotates, it drives the cable 233 to rotate forward or backward around the wire winding wheel 232.

[0065] Specifically, external teeth 2311 are provided on the outer periphery of the output shaft, and internal teeth 2322 meshing with the external teeth 2311 are provided on the inner wall of the wire winding wheel 232. When the first motor 231 drives the output shaft to rotate forward or backward, it synchronously drives the wire winding wheel 232 to rotate forward or backward, and finally drives the lengths of the two ends of the cable 233 on the wire winding wheel 232 to change, so as to realize the linear sliding of the movable guide rail 21.

[0066] In the present embodiment, refer to Figure 11 As shown, 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 head 237. The first cable end fixing plate 236 is fixed to the first end 211 of the movable guide rail 21 and is close to the side of the first driving member 23. A first notch 2361 is provided on the first cable end fixing plate 236, and the first nail head 237 connects the tail 2332 of the cable 233 and is fixed in the first notch 2361.

[0067] The second cable end fixing part includes a second cable end fixing plate 238 and a second nail cap (not shown in the figure). The second cable end fixing plate 238 is fixed to the second end 212 of the movable guide rail 21 and is close to 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 is provided with a second notch 2381. The second nail cap connects the end 2331 of the cable 233 and is fixed in the second notch 2381.

[0068] Further, in order to ensure the stability of the cable 233 during movement and reduce the tension of the cable 233, so that the linear sliding of the movable guide rail 21 connected to the cable 233 is smoother, the first driving member 23 further includes a first bracket 234 and a second bracket 235. The first bracket 234 is arranged on the top of the mounting plate 10 and is located at the first end 211 of the movable guide rail 21. 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 through the second cable end fixing part. 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 through the first cable end fixing part.

[0069] Wherein, in order to avoid the 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 vertically.

[0070] The following respectively elaborates on a feasible embodiment of the elongation and contraction of the first driving member 23.

[0071] Elongation process:

[0072] The first motor 231 drives the wire reel 232 to rotate counterclockwise. At this time, the tail 2332 of the cable 233 is released and elongated from the groove 2321, and at the same time, the end 2331 of the cable 233 is contracted and wound into the groove 2321. When the end 2331 of the cable 233 is contracted and wound into the groove 2321, it drives the second cable end fixing part to move in the direction close to the first bracket 234, that is, the elongation of the movable guide rail 21 is realized.

[0073] Contraction process:

[0074] After the above elongation process is completed and the in-vehicle ceiling screen needs to be retracted, the first motor 231 drives the wire reel 232 to rotate clockwise. At this time, the end 2331 of the cable 233 is released and elongated from the groove 2321, and the tail 2332 of the cable 233 is contracted and wound into the groove 2321. When the tail 2332 of the cable 233 is contracted and wound into the groove 2321, it drives the first cable end fixing part to move in the direction close to the first bracket 234, that is, as Figure 1 shown, the movable guide rail 21 is completely contracted, and the first cable end fixing part moves to the vicinity of the first bracket 234.

[0075] Furthermore, in this embodiment, referring to Figure 1 and Figures 14 - 15 shown, an installation part is provided on the upper side of the installation plate 10. The installation part includes a wire reel base 13 and a wire reel cover plate 14. The wire reel base 13 is arranged on the upper side of the installation plate 10, and the wire reel cover plate 14 is buckled on the wire reel base 13 to form a chamber for accommodating the first motor 231 and the wire reel 232.

[0076] Optionally, the wire reel base 13 is integrally formed with the installation plate 10. After the wire reel cover plate 14 and the wire reel base 13 are buckled, they are fixed by screws, thereby playing a role in limiting the first motor 231 and the wire reel 232 in the chamber. In order to facilitate the cable 233 to extend out of the chamber, a wire guiding groove 141 for the cable 233 to extend or contract is also provided on the wire reel cover plate 14 as shown in Figure 5 .

[0077] Of course, the above-mentioned is only an embodiment for driving the movable guide rail 21 to translate along the length direction of the vehicle. This application includes but is not limited to this. It can also be through the sliding fit of a slider and a slide rail or chain drive, etc. The specific translation structure of the movable guide rail 21 is not limited here.

[0078] In a possible implementation manner, as shown in Figure 1 , two sets of translation assemblies 20 are provided and are symmetrically arranged at both ends of the upper side of the installation plate 10 respectively to enhance the stability of the horizontal movement of the movable guide rail 21. Of course, one set of translation assembly 20 can also be set. Preferably, when one set of translation assembly 20 is set, the translation assembly 20 is arranged at the middle position of the top of the installation plate 10; in addition, multiple sets of translation assemblies 20 such as three sets and four sets can be set in combination with the size of the installation plate 10, which is not limited here specifically.

[0079] Among them, the size of the display screen 31 in the vehicle width direction is greater than or equal to the size of the installation plate 10 and the translation assembly 20 in the vehicle width direction. Therefore, the installation plate 10 and the translation assembly 20 can be blocked by the display screen 31, so that a feeling of floating movement is generated during the linear sliding of the display screen 31, improving the riding experience of the occupants.

[0080] The display screen 31 is connected to the movable guide rail 21 in the translation assembly 20. Specifically, when there are two sets of the translation assembly 20, there are two display screen connectors 32 which are respectively connected to the two ends of the two sets of the translation assembly 20 and the display screen 31. Optionally, in an alternative embodiment, the display screen connector 32 is rotatably connected to the movable guide rail 21, and thus the viewing angle of the display screen 31 connected to the other end of the display screen connector 32 can be rotationally adjusted to meet the different viewing angle requirements of the passengers.

[0081] Certainly, in another alternative embodiment, 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 rotation structure of the display screen 31 itself or the rotation mechanism connected to the display screen 31, and thus the viewing angle between the display screen 31 and the passengers is adjusted.

[0082] As Figure 1 shown, there are two sets of the translation assembly 20 which are symmetrically arranged at the two ends of the top of the mounting plate 10 respectively. In order to reduce the weight of the first driving member 23 and simplify the structure of the first driving member 23, the first driving member 23 is only arranged at one end of the mounting plate 10, that is, only one set of the first driving member 23 is provided. However, considering that it is necessary to synchronously drive the other set of the translation assembly 20 to move, the same display screen 31 is connected by the two display screen connectors 32 as above. When the first driving member 23 drives the movable guide rail 21 on one set of the translation assembly 20 to slide, the display screen connector 32 correspondingly connected to the movable guide rail 21 moves synchronously, and thus drives the display screen 31 to move. Finally, the other set of the translation assembly 20 connected to the other end of the display screen 31 also moves synchronously.

[0083] Furthermore, the in-vehicle ceiling-mounted screen further includes a connecting plate 24 which is arranged below the mounting plate 10 and connected to the movable guide rail 21; in this embodiment, the connecting plate 24 is connected to the two movable guide rails 21, and thus when the movable guide rail 21 on one set of the translation assembly 20 slides, the movable guide rail 21 on the other set of the translation assembly 20 can be directly driven to slide through the connecting plate 24.

[0084] Optionally, as shown in Figure 2 , the in-vehicle ceiling-mounted screen further includes a flipping assembly 40 which is arranged on the connecting plate 24. The flipping assembly 40 is connected to the display screen 31 and drives the display screen 31 to flip up and down, and thus the viewing angle of the passengers to the display screen is increased, and the driving and riding experience of the passengers is improved. Among them Figures 3 - 8 shows a schematic diagram of the open or closed state when the display screen 31 moves to the front end or the rear end.

[0085] As Figure 3 and Figure 15As shown in the figure, the mounting plate 10 has 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 a vertically arranged plate and integrally formed to improve the overall structural strength of the mounting plate 10. Of course, the bottom plate 15 and the top plate 16 can also be connected by plates of other structures, which is not limited here.

[0086] Among them, the first driving member 23 is arranged in the second receiving space 18, and the highest point of the first driving member 23 at the second receiving space 18 is not higher than the upper side height of the top plate 16. Part of the flipping assembly 40 is located in the first receiving space 17, reducing the external leakage of the flipping assembly 40 and making the overall structure of the ceiling screen beautiful.

[0087] Specifically, the flipping assembly 40 includes a link assembly 41 and a second driving member 42. One end of the link assembly 41 is fixedly connected to the display screen 31, and the other end of the link assembly 41 is hinged to the second driving member 42. The second driving member 42 drives the link assembly 41 to move along the length direction of the vehicle, and then drives the link assembly 41 to rotate, and finally the display screen 31 fixed on the link assembly 41 realizes flipping.

[0088] In a possible implementation manner, in order to improve the connection stability between the link assembly 41 and the display screen 31, the display screen assembly 30 further includes a display screen shaft 33. The display screen 31 is connected to the display screen shaft 33, and both ends of the display screen shaft 33 are respectively connected to a display screen connecting member 32. One end of the link assembly 41 is fixedly connected to the middle part of the display screen shaft 33.

[0089] The link assembly 41 includes a first link 411 and a second link 412. One end of the first link 411 is fixedly connected to the display screen shaft 33. Preferably, one end of the first link 411 is fixedly connected to the middle part of the display screen shaft 33. The other end of the first link 411 is hinged to one end of the second link 412, and the other end of the second link 412 is hinged to the second driving member 42.

[0090] Among them, a strip-shaped notch 241 for the first link 411 and the second link 412 to rotate is provided at one end of the connecting plate 24 close to the display screen 31. In this embodiment, as Figure 4 shown, when the second link 412 abuts in the strip-shaped notch 241, due to the length limitation of the strip-shaped notch 241, the second link 412 cannot continue to rotate downward. At this time, the hinge point of the first link 411 and the second link 412 is located above the connection center line of the connection center of the first link 411 and the display screen 31 and the connection center of the second link 412 and the second driving member 42. The advantage of such a design is that it is convenient for the first link 411 and the second link 412 to drive the display screen 31 to rotate reversely along the original rotation path to the closed state.

[0091] Certainly, in this embodiment, the sliding distance of the slider 421 and the lengths of the first link 411 and the second link 412 also further limit the first link 411 from driving the second link 412 to continue rotating downward in the original rotation direction, causing the display screen 31 to continue flipping upward along the original rotation direction after flipping downward, and unable to rotate to the closed state.

[0092] In addition, the second driving member 42 includes a slider 421, a second motor 422, and a lead screw 423. The other end of the second link 412 is hinged to the slider 421, and the second motor 422 drives the slider 421 to translate on the lead screw 423, thereby driving the rotation of the second link 412.

The ceiling-mounted screen fixing member 12 is fixed on the upper side of the top plate 16, that is, the upper side of the mounting plate 10. The dimension of the display screen 31 in the vehicle width direction is greater than or equal to the dimension of the ceiling-mounted screen fixing member 12 in the vehicle width direction. Thus, the ceiling-mounted screen fixing member 12 can also be blocked by the display screen 31, achieving the effect of the display screen 31 floating. Specifically, in a possible implementation manner, glue application layers are provided around the top of the ceiling-mounted screen fixing member 12, and after applying glue in the glue application layers, it is bonded to the sunroof glass or the roof sheet metal.

[0094] In addition, a ceiling-mounted screen mounting hole 11 is provided on the mounting plate 10, and the bottom of the ceiling-mounted screen fixing member 12 is detachably mounted on the ceiling-mounted screen mounting hole 11, for example, by cooperating with bolts and nuts. It should be noted that in order to reduce the contact between the ceiling-mounted screen fixing member 12 and the first driving member 23 and affect the driving effect of the first driving member 23 or the fixing effect of the ceiling-mounted screen fixing member 12 on the vehicle roof, the ceiling-mounted screen fixing member 12 and the first driving member 23 are arranged staggeredly.

[0095] Optionally, referring to Figure 10 As shown, the in-vehicle ceiling-mounted screen further includes a curtain winding and retracting assembly 50. The curtain winding and retracting assembly 50 includes a winding mechanism 51 and a curtain 52. The winding 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 inside the winding mechanism 51. When the display screen 31 flips downward, it synchronously drives the winding mechanism 51 to move downward. Thus, the curtain 52 inside the winding mechanism 51 is pulled out, and at the same time, it can cooperate with the projection device to realize viewing from both sides of the display screen 31 and the curtain 52, so as to meet the viewing needs of two rows of occupants.

[0096] Optionally, referring to Figure 9As shown, the vehicle-mounted ceiling screen further includes a lighting component 60, including but not limited to a ceiling lamp. The lighting component 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 component 60 is gradually exposed as the display screen 31 moves.

[0097] Corresponding to the foregoing embodiments of the vehicle-mounted ceiling screen, this specification also provides an embodiment of a vehicle applying the vehicle-mounted ceiling screen. By bonding the above-mentioned vehicle-mounted ceiling screen to the skylight glass or roof sheet metal of the vehicle, the requirements of different occupants' human-machine visual distances can be met, and the driving and riding experience of the occupants can be improved.
