Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle-mounted accessories, and particularly relates to a vehicle-mounted ceiling screen device and a vehicle. BACKGROUND

[0002] With the continuous improvement of people's living standards, various supporting devices of vehicles are also increasingly complete. The vehicle-mounted ceiling screen, as a vehicle-mounted device for realizing information interaction between people and vehicles, has a wide application on vehicles. The vehicle-mounted ceiling screen is usually installed on the top of a vehicle and can play multimedia information to meet the use requirements of rear passengers such as audio-visual entertainment, games, or video conferencing. The existing vehicle-mounted ceiling screen is generally fixed on the top of the vehicle and cannot be moved, which leads to a fixed distance between the vehicle-mounted ceiling screen and the rear passengers during use, and cannot meet the viewing requirements of passengers at different positions, and the use comfort is poor. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a vehicle-mounted ceiling screen device and a vehicle, which can move the vehicle-mounted ceiling screen during use, take into account the viewing requirements of passengers at different positions, and improve the use experience of passengers.

[0004] In a first aspect, the present application provides a vehicle-mounted ceiling screen device, which comprises:

[0005] a first track mechanism;

[0006] a second track mechanism, which is connected to the first track mechanism and can slide on the first track mechanism in a first direction, the first direction being the length direction of the vehicle;

[0007] a sliding mechanism, which is connected to the second track mechanism and can slide on the second track mechanism in a second direction, the second direction being the width direction of the vehicle, and the sliding mechanism is used for being connected with the display screen.

[0008] It can be understood that, since the sliding mechanism is slidingly connected to the second track mechanism, and the second track mechanism is slidingly connected to the first track mechanism. Therefore, when the second track mechanism slides on the first track mechanism in the first direction, the sliding mechanism will be driven to slide in the first direction. Since the sliding mechanism can also slide on the second track mechanism in the second direction. Therefore, the sliding mechanism can realize self-defined movement in the first direction and / or the second direction relative to the first track mechanism.

[0009] Based on the connection relationship between the sliding mechanism and the display screen, the display screen and the sliding mechanism can realize linkage. That is, when the sliding mechanism slides relative to the first track mechanism along the first direction and / or the second direction, it will drive the display screen to slide relative to the first track mechanism along the second direction and / or the first direction synchronously. Therefore, the position of the display screen in the vehicle interior can be constantly changed to meet the viewing distance requirements of passengers in different seats in the passenger compartment, so as to meet the viewing requirements of passengers and improve the viewing experience of passengers.

[0010] In a possible implementation, the first track mechanism includes two first sliding rails, the two first sliding rails extend along the first direction and are spaced apart in the second direction, and the two ends of the second track mechanism are respectively connected to the two first sliding rails.

[0011] It can be understood that, by connecting the two ends of the second track mechanism to the two first sliding rails respectively, the sliding stability and reliability of the second track mechanism as a whole can be improved, so that the sliding action of the second track mechanism on the first track mechanism can have better consistency and be more balanced in force.

[0012] In a possible implementation, the first track mechanism further includes two first lead screws, the two first lead screws are respectively connected to the two first sliding rails, each first lead screw extends along the first direction, and the two ends of the second track mechanism are respectively sleeved on the two first lead screws, and the second track mechanism can slide along the first direction on the two first sliding rails under the driving of the two first lead screws.

[0013] It can be understood that, by sleeving the two ends of the second track mechanism on the two first lead screws respectively, the rotational motion of the first lead screws can be converted into the linear motion of the second track mechanism by using the motion characteristics of the first lead screws, so that the second track mechanism can be driven by the first lead screws to slide along the first direction on the first sliding rails, which is beneficial to reducing the frictional resistance between the second track mechanism and the first track mechanism and improving the transmission efficiency between the second track mechanism and the first track mechanism.

[0014] In a possible implementation, the second track mechanism includes a second sliding rail, at least two sliding blocks, and at least two first connecting pieces.

[0015] The second sliding rail is arranged in a stack with the two first sliding rails, and extends along the second direction.

[0016] The at least two sliding blocks are fixedly connected to the bottom surface of the second sliding rail and are located at the two ends of the second sliding rail along the second direction, and the at least two sliding blocks are further connected to the two first sliding rails.

[0017] At least two first connecting members are fixedly connected to the bottom surface of the second slide rail and located at both ends of the second slide rail along the second direction. The at least two first connecting members are sleeved on the two first lead screws and can move along the first direction on the two first lead screws, and drive the at least two sliding blocks to slide along the first direction on the two first slide rails through the second slide rail.

[0018] It can be understood that, by fixedly connecting the at least two sliding blocks with the second slide rail and slidably connecting the at least two sliding blocks with the two first slide rails, not only the sliding connection between the second slide rail and the two first slide rails can be realized, but also the second slide rail can be arranged at a height relative to the two first slide rails, which is beneficial to avoiding the problem that the sliding mechanism arranged on the second slide rail interferes with the first slide rail due to the direct contact between the second slide rail and the two first slide rails, so that the vehicle-mounted ceiling screen device fails.

[0019] By movably connecting the first connecting member with the first lead screw, the first connecting member can be driven by the first lead screw to move linearly along the axial direction of the first lead screw when the first lead screw rotates, thereby driving the second slide rail to slide on the first slide rail, and the first connecting member can be controlled by the first lead screw to stop moving linearly along the axial direction of the first lead screw when the first lead screw stops rotating, thereby stopping the second slide rail from sliding on the first slide rail. That is, by slidably connecting the sliding blocks with the first slide rail and movably connecting the first connecting member with the first lead screw, the sliding and starting and stopping of the second rail mechanism on the first rail mechanism can be realized.

[0020] In a possible implementation, the second rail mechanism further includes a second lead screw connected to the second slide rail and extending along the second direction, and the sliding mechanism is slidably connected to the second slide rail and sleeved on the second lead screw and can slide along the second direction on the second slide rail under the drive of the second lead screw.

[0021] It can be understood that, by sleeving the sliding mechanism on the second lead screw, the rotary motion of the second lead screw can be converted into the linear motion of the sliding mechanism by using the motion characteristics of the second lead screw, so that the sliding mechanism can be driven by the second lead screw to slide along the second direction on the second slide rail, which is beneficial to reducing the frictional resistance between the sliding mechanism and the second rail mechanism and improving the transmission efficiency between the sliding mechanism and the second rail mechanism.

[0022] In a possible implementation, the sliding mechanism includes a mounting plate, at least two pulleys, and at least one second connecting member.

[0023] The mounting plate is located on the side of the second slide rail away from the first rail mechanism, and the mounting plate is used to be connected with the display screen.

[0024] At least two of the pulleys are fixedly connected to the back of the mounting plate and located on both sides of the mounting plate along the first direction, and the at least two pulleys are also slidingly connected to the second slide rail;

[0025] At least one of the second connectors is fixedly connected to the back of the mounting plate and located between the at least two pulleys, the at least one second connector is sleeved on the second lead screw, the at least one second connector can move on the second lead screw along the second direction, and the at least one second connector can drive the at least two pulleys to slide on the second slide rail along the second direction through the mounting plate.

[0026] It can be understood that the pulleys are used to achieve the sliding connection between the mounting plate and the second slide rail, which not only can make the sliding mechanism have better appearance and concealment, i.e., the sliding mechanism has better appearance performance, but also can reduce the noise generated when the sliding mechanism slides, so that the sliding mechanism can slide on the second rail mechanism with smaller sound.

[0027] By slidingly connecting the at least two pulleys with the second slide rail along the two sides of the first direction, the sliding connection between the mounting plate and the second slide rail can be achieved, and the installation space of the at least two pulleys can reuse a part of the side space of the second slide rail, effectively reducing the space occupied by the sliding mechanism in the thickness direction of the vehicle ceiling screen device, which is beneficial to the light and thin of the vehicle ceiling screen device.

[0028] In a possible implementation, the vehicle ceiling screen device further comprises a display screen, the display screen is connected to the sliding mechanism and can be driven by the sliding mechanism to move relative to the first rail mechanism along the first direction and the second direction.

[0029] In a possible implementation, the display screen is rotationally connected with the sliding mechanism, the display screen can be closed relative to the sliding mechanism and stored in the sliding mechanism, or the display screen can be opened relative to the sliding mechanism for display.

[0030] It can be understood that by rotationally connecting the display screen with the sliding mechanism, the display screen can be opened relative to the sliding mechanism for large-screen display when the display screen is needed, so as to provide more information for the user and provide better user experience. When the display screen is not needed, the display screen is stored in the sliding mechanism, so that the vehicle ceiling screen device has smaller volume, reduces the occupation of the space in the vehicle, expands the visual transparency of the cabin, and brings better cabin experience.

[0031] In a possible implementation, the sliding mechanism further comprises a rotating shaft mechanism connected between the display screen and the mounting plate, the display screen rotates relative to the mounting plate about at least two rotating center lines through the rotating shaft mechanism, the at least two rotating center lines comprise a first rotating center line and a second rotating center line, the first rotating center line is arranged in parallel with the second direction, and the second rotating center line is arranged in parallel with a third direction, the third direction being a height direction of the vehicle.

[0032] It can be understood that, by rotating the display screen about the first rotating center line, the folding angle of the display screen relative to the sliding mechanism can be controlled, so that the included angle between the display screen and the sliding mechanism is at a comfortable viewing angle of the passenger, and the viewing experience comfort of the passenger is improved. By rotating the display screen about the second rotating center line, the circumferential rotation angle of the display screen can be controlled according to different positions of the passenger, so that the display surface of the display screen can face the face of the passenger, and the viewing comfort of the passenger is ensured.

[0033] In a possible implementation, the sliding mechanism further comprises a lifting mechanism, the lifting mechanism being liftable connected between the mounting plate and the display screen, and the lifting mechanism being configured to drive the display screen to move relative to the sliding mechanism along the third direction.

[0034] It can be understood that, by arranging the lifting mechanism, the display screen can be driven to ascend or descend relative to the mounting plate, so that the distance between the display screen and the passenger in the third direction is adjusted, and the passenger can better use the display screen for interaction.

[0035] In a possible implementation, the vehicle-mounted ceiling screen device further comprises a driving mechanism and a control unit.

[0036] The driving mechanism is connected with the first track mechanism and the second track mechanism, the driving mechanism is configured to drive the second track mechanism to slide on the first track mechanism along the first direction, and the driving mechanism is further configured to drive the sliding mechanism to slide on the second track mechanism along the second direction.

[0037] The control unit is electrically connected with the driving mechanism and is configured to control the opening and closing of the driving mechanism.

[0038] It can be understood that, by connecting the driving mechanism with the first track mechanism and the second track mechanism, the driving mechanism can be used as a power source for the second track mechanism to slide on the first track mechanism and the sliding mechanism to slide on the second track mechanism, so that the sliding actions of the second track mechanism and the sliding mechanism can be more smooth and smooth. In addition, the driving mechanism is controlled by the control unit, the starting and stopping of the second track mechanism on the first track mechanism and the starting and stopping of the sliding mechanism on the second track mechanism can be controlled, so that the starting and stopping of the display screen in the second direction and the first direction can be realized, and the reliability is good.

[0039] In a possible implementation, the display screen comprises a camera, the camera is electrically connected with the control unit, and the control unit is configured to control the second track mechanism and the sliding mechanism to slide according to a captured image of the camera, so that the display screen is in a preset position.

[0040] It can be understood that, because the camera has a shooting function, it can capture the image of the passenger in front of it to form a captured image. When the position of the passenger's face meets the optimal viewing position of the display screen, it can be determined that the passenger is in a good viewing position, and the passenger can have a good use experience. When the position of the passenger's face does not meet the optimal viewing position of the display screen, it can be determined that the passenger is in a poor viewing position, and at this time, the position of the display screen needs to be moved to ensure that the passenger's face is always in the optimal viewing position of the display screen.

[0041] In a second aspect, the application also provides a vehicle, which comprises a vehicle body and a vehicle-mounted ceiling screen device as described above, and the vehicle-mounted ceiling screen device is connected to the top of the vehicle body.

[0042] In a possible implementation, the vehicle further comprises a sunroof glass and a sunshade curtain mechanism, and the sunroof glass and the sunshade curtain mechanism are connected to the vehicle body.

[0043] The sunshade curtain mechanism comprises a roller shutter track mechanism and a roller shutter, the roller shutter track mechanism is located at the edge of the sunroof glass, the roller shutter is wound on the roller shutter track mechanism and can move in the first direction under the drive of the roller shutter track mechanism to cover or expose the sunroof glass, and the first track mechanism is located between the edge of the sunroof glass and the roller shutter track mechanism.

[0044] In a possible implementation, the vehicle further comprises a sunroof glass and a sunshade curtain mechanism, and the sunroof glass and the sunshade curtain mechanism are connected to the vehicle body.

[0045] The sunshade curtain mechanism comprises the first track mechanism and a roller curtain, the roller curtain is wound on the first track mechanism and can be moved along the first direction under the driving of the first track mechanism to cover or uncover the sunroof glass.

[0046] It can be understood that multiplexing the track in the first track mechanism as the track of the sunshade curtain mechanism can make the first track mechanism have the dual functions of winding the roller curtain and providing the slide for the second track mechanism, which is beneficial to realize the multifunctionalization of the first track mechanism, improve the space utilization of the vehicle, and improve the aesthetics and concealment of the structure in the vehicle.

[0072] The specific embodiments of the present application will be clearly described below with reference to the drawings.

[0073] The embodiments of the present application provide a vehicle-mounted ceiling screen device and a vehicle. The vehicle can be, but is not limited to, a pure electric vehicle, a range-extended electric vehicle, a hybrid electric vehicle, a fuel cell vehicle, a new energy vehicle, etc.

[0074] Please refer to Figure 1 , Figure 1 is an angle structure schematic diagram of the vehicle 200 provided by the embodiments of the present application.

[0075] In the following, in order to facilitate the description, the length direction of the vehicle 200 is defined as the first direction, the width direction of the vehicle 200 is defined as the second direction, and the height direction of the vehicle 200 is defined as the third direction. The first direction is identified as the Y-axis direction in the drawing, the second direction is identified as the X-axis direction in the drawing, and the third direction is identified as the Z-axis direction in the drawing. The X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other. In addition, the X direction referred to below includes the X-axis positive direction and the X-axis negative direction, wherein the arrow in the drawing indicates the X-axis positive direction, and the opposite direction of the arrow indicates the X-axis negative direction. The Y direction referred to below includes the Y-axis positive direction and the Y-axis negative direction, wherein the arrow in the drawing indicates the Y-axis positive direction, and the opposite direction of the arrow indicates the Y-axis negative direction. The Z direction referred to below includes the Z-axis positive direction and the Z-axis negative direction, wherein the arrow in the drawing indicates the Z-axis positive direction, and the opposite direction of the arrow indicates the Z-axis negative direction.

[0076] The vehicle 200 can include a vehicle body 210, a sunroof glass 220 and a vehicle-mounted ceiling screen device 100. The sunroof glass 220 can be connected to the top of the vehicle body 210 and constitute part of the appearance structure of the vehicle 200. The sunroof glass 220 can increase the ventilation of the vehicle 200, provide more lighting, widen the passenger's field of view, and bring the passenger a more comfortable riding experience. The vehicle-mounted ceiling screen device 100 can be located inside the vehicle body 210 and connected to the top of the vehicle body 210, and arranged close to the sunroof glass 220. The vehicle-mounted ceiling screen device 100 can be used to play multimedia information to meet the use needs of rear passengers such as audio and video entertainment, games, video conferencing, etc., and realize the information interaction between the passengers and the vehicle 200.

[0077] It should be noted that, Figure 1 The purpose of the above is only to schematically describe the connection relationship of the vehicle body 210, the sunroof glass 220 and the vehicle ceiling suction screen device 100, and is not a specific limitation on the connection position, specific structure and number of each component. The structure schematically shown in the embodiment does not constitute a specific limitation on the vehicle 200. In other embodiments of the present application, the vehicle 200 can include more or fewer components than Figure 1 shown, or combine certain components, or split certain components, or different component arrangements. Figure 2 The components shown can be implemented in hardware, software, or a combination of software and hardware.

[0078] It can be understood that in the related art, the vehicle ceiling suction screen in the vehicle ceiling suction screen device is generally fixed to the top of the vehicle and cannot be moved, which leads to a fixed distance between the vehicle ceiling suction screen and the rear passengers during use, and cannot meet the viewing needs of passengers in different positions, and the use comfort is poor.

[0079] In order to solve the above problems, the embodiment of the present application provides a vehicle ceiling suction screen device 100, which can move the vehicle ceiling suction screen during use, taking into account the viewing needs of passengers in different seats, improving the use experience of passengers, which will be described in detail below.

[0080] Please refer to Figure 2 , Figure 2 is a structural schematic diagram of the vehicle ceiling suction screen device 100 provided by the embodiment of the present application.

[0081] The vehicle ceiling suction screen device 100 can include a first track mechanism 10, a second track mechanism 20 and a sliding mechanism 30. The first track mechanism 10 can be connected to the vehicle body 210 and disposed adjacent to the outer edge of the sunroof glass 220. The first track mechanism 10 can extend along the length direction of the sunroof glass 220, i.e. along the Y direction. The second track mechanism 20 can be connected to the first track mechanism 10 and can reciprocate along the Y direction on the first track mechanism 10. The second track mechanism 20 can extend along the width direction of the sunroof glass 220, i.e. along the X direction, and span the sunroof glass 220. The sliding mechanism 30 can be connected to the second track mechanism 20 and can reciprocate along the X direction on the second track mechanism 20. The sliding mechanism 30 is used to connect with the display screen 40.

[0082] It is understandable that, since the sliding mechanism 30 is slidably connected to the second track mechanism 20, and the second track mechanism 20 is in turn slidably connected to the first track mechanism 10, when the second track mechanism 20 slides along the Y direction on the first track mechanism 10, the sliding mechanism 30 will be driven to slide along the Y direction as well. Furthermore, the sliding mechanism 30 can also slide along the X direction on the second track mechanism 20. Therefore, the sliding mechanism 30 can achieve customized movement relative to the first track mechanism 10 in the X and / or Y directions.

[0083] Based on the connection between the sliding mechanism 30 and the display screen 40, the display screen 40 and the sliding mechanism 30 can be linked. That is, when the sliding mechanism 30 slides relative to the first track mechanism 10 in the X and / or Y directions, it will drive the display screen 40 to slide synchronously relative to the first track mechanism 10 in the X and / or Y directions. Therefore, the position of the display screen 40 inside the vehicle 200 is not fixed but can be continuously changed to flexibly adjust according to the different viewing distance needs of passengers in different seats in the passenger compartment, thereby meeting passengers' viewing needs and improving their viewing experience.

[0084] It should be noted that, Figure 2 The purpose is merely to schematically illustrate the connection relationship between the first track mechanism 10, the second track mechanism 20, and the sliding mechanism 30, and is not to specifically limit the connection positions, specific structures, or quantities of each component. Furthermore, the structure illustrated in this embodiment does not constitute a specific limitation on the vehicle-mounted ceiling-mounted screen device 100. In other embodiments of this application, the vehicle-mounted ceiling-mounted screen device 100 may include... Figure 2 This may involve more or fewer components, or combining certain components, or splitting certain components, or different component arrangements. Figure 2 The components shown can be implemented in hardware, software, or a combination of both.

[0085] Please refer to the following: Figure 3 and Figure 3 , Figure 2 It is along Figure 2 The diagram shows a simplified cross-sectional view of a portion of the structure of the first track mechanism 10 obtained by cutting along section line AA.

[0086] The first track mechanism 10 may include two first slide rails 11. Both first slide rails 11 may be connected to the top of the vehicle body 210 and located on opposite sides of the sunroof glass 220 in the width direction (X direction in the diagram). The two first slide rails 11 may extend along the X direction and be spaced apart in the X direction. The structures of the two first slide rails 11 may be similar, identical, or different. The extension length of each first slide rail 11 along the Y direction may be less than, equal to, or greater than the extension length of the sunroof glass 220 along the Y direction.

[0087] The first track mechanism 10 can further include two first lead screws 12. The two first lead screws 12 are respectively connected to the two first sliding rails 11. The two first lead screws 12 can extend along the Y direction and are spaced apart in the X direction. Each first lead screw 12 can rotate about a central axis thereof relative to the first sliding rail 11 connected thereto. That is, one first lead screw 12 can be rotatably connected to one first sliding rail 11, and the other first lead screw 12 can be rotatably connected to the other first sliding rail 11. The two first lead screws 12 can be similar, identical or different in structure. The extension length of each first lead screw 12 along the Y direction can be less than, equal to or greater than the extension length of the first sliding rail 11 connected thereto along the Y direction. Exemplarily, the first lead screw 12 can be a ball screw.

[0088] In the embodiment of the present application, the two ends of the second track mechanism 20 are respectively slidably connected to the two first sliding rails 11 to achieve the slidable connection of the second track mechanism 20 and the first track mechanism 10. Specifically, the two ends of the second track mechanism 20 can be respectively sleeved on the two first lead screws 12. The second track mechanism 20 can slide along the Y direction on the two first sliding rails 11 under the driving of the two first lead screws 12. That is, the first lead screw 12 can control the start and stop of the second track mechanism 20 in the Y direction and determine the specific position of the display screen 40 in the Y direction.

[0089] It can be understood that by slidably connecting the two ends of the second track mechanism 20 to the two first sliding rails 11 respectively, the sliding stability and reliability of the second track mechanism 20 as a whole can be improved, so that the sliding action of the second track mechanism 20 on the first track mechanism 10 can have better consistency and be more balanced in stress.

[0090] By sleeving the two ends of the second track mechanism 20 on the two first lead screws 12 respectively, the rotational motion of the first lead screw 12 can be converted into the linear motion of the second track mechanism 20 by utilizing the motion characteristics of the first lead screw 12, so that the second track mechanism 20 can be driven by the first lead screw 12 to slide along the Y direction on the first sliding rail 11, which is conducive to reducing the frictional resistance between the second track mechanism 20 and the first track mechanism 10 and improving the transmission efficiency between the second track mechanism 20 and the first track mechanism 10.

[0091] Please refer to Figure 4 and Figure 4 , Figure 2 is Figure 4 the structural schematic diagram of the second track mechanism 20 of the vehicle-mounted ceiling screen device 100 shown in

[0092] The second rail mechanism 20 can include a second slide rail 21, at least two sliding blocks 22, and at least two first connecting members 23. The second slide rail 21 can be located on the side of the two first slide rails 11 away from the sunroof glass 220 and arranged in a stack with the two first slide rails 11. The second slide rail 21 can extend along the X direction and be capable of sliding along the Y direction on the two first slide rails 11. The second slide rail 21, the two first slide rails 11, and the sunroof glass 220 can be arranged in sequence along the Z direction.

[0093] The second slide rail 21 can include a top surface 211, a bottom surface 212, a first side surface 213, and a second side surface 214. The bottom surface 212 and the top surface 211 can be arranged opposite to each other along the thickness direction (the Z direction shown in the figure) of the second slide rail 21. The bottom surface 212 can face the first rail mechanism 10, and the top surface 211 can face away from the first rail mechanism 10. The first side surface 213 and the second side surface 214 can be arranged opposite to each other along the width direction (the Y direction shown in the figure) of the second slide rail 21 and connected between the top surface 211 and the bottom surface 212.

[0094] The second slide rail 21 can be provided with a mounting hole 215, a first sliding groove 216, and a second sliding groove 217. The mounting hole 215 can pass through the top surface 211 and the bottom surface 212. That is, the mounting hole 215 can pass through the second slide rail 21 along the thickness direction of the second slide rail 21. The opening of the first sliding groove 216 can be located on the first side surface 213. The first sliding groove 216 can be recessed from the first side surface 213 to the inside of the second slide rail 21. The opening of the second sliding groove 217 can be located on the second side surface 214, and the second sliding groove 217 can be recessed from the second side surface 214 to the inside of the second slide rail 21.

[0095] The at least two sliding blocks 22 can be fixedly connected to the bottom surface 212 of the second slide rail 21 and located at the two ends of the second slide rail 21 along the X direction. The at least two sliding blocks 22 can also be slidably connected to the two first slide rails 11 to achieve the sliding connection between the second rail mechanism 20 and the two first slide rails 11. For example, the first sliding groove 216 and the second sliding groove 217 can be symmetrically arranged. The number of sliding blocks 22 can be eight. Among the eight sliding blocks 22, every two sliding blocks form a sliding block group, thereby forming four sliding block groups. The four sliding block groups can be arranged at the four corners of the second slide rail 21, respectively. Each sliding block group can be slidably connected to one first slide rail 11. Of course, in other embodiments, the sliding connection between the second rail mechanism 20 and the first rail mechanism 10 can also be achieved by other ways.

[0096] It can be understood that by fixing the at least two sliding blocks 22 to the second sliding rail 21 and slidingly connecting them to the two first sliding rails 11, not only can the sliding connection between the second sliding rail 21 and the two first sliding rails 11 be achieved, but also the second sliding rail 21 can be arranged in a raised manner relative to the two first sliding rails 11, which is beneficial to avoid the problem that the sliding mechanism 30 arranged on the second sliding rail 21 interferes with the first sliding rail 11 due to direct contact between the second sliding rail 21 and the two first sliding rails 11, so that the vehicle-mounted ceiling screen device 100 fails.

[0097] Please refer to Figure 5 and Figure 5 , Figure 2 is Figure 6 the schematic diagram of the assembled structure of the first rail mechanism 10 and the second rail mechanism 20 of the vehicle-mounted ceiling screen device 100 shown in FIG. 1.

[0098] The at least two first connecting members 23 are fixedly connected to the bottom surface 212 of the second sliding rail 21 and are located at both ends of the second sliding rail 21 along the X direction. The at least two first connecting members 23 are sleeved on the two first lead screws 12 and are arranged at intervals with the at least two sliding blocks 22. The at least two first connecting members 23 can move along the Y direction on the two first lead screws 12 and drive the at least two sliding blocks 22 to slide along the Y direction on the two first sliding rails 11 through the second sliding rail 21. That is, the at least two first connecting members 23 can be used to control the start and stop of the second rail mechanism 20 in the Y direction. Exemplarily, the number of the first connecting members 23 can be two. The two first connecting members 23 are respectively sleeved on the two first lead screws 12. Each first connecting member 23 can be driven by one first lead screw 12 to move or stop along the Y direction on the first lead screw 12.

[0099] It can be understood that by arranging the first connecting member 23 and movably connecting the first connecting member 23 to the first lead screw 12, not only can the first connecting member 23 be driven by the first lead screw 12 to move linearly along the axial direction of the first lead screw 12 when the first lead screw 12 rotates, thereby driving the second sliding rail 21 to slide on the first sliding rail 11, but also the first connecting member 23 can be controlled by the first lead screw 12 to stop moving linearly along the axial direction of the first lead screw 12 when the first lead screw 12 stops rotating, thereby stopping the second sliding rail 21 from sliding on the first sliding rail 11. That is, by the sliding connection between the sliding block 22 and the first sliding rail 11 and the movable connection between the first connecting member 23 and the first lead screw 12, the sliding and start-stop of the second rail mechanism 20 on the first rail mechanism 10 can be achieved.

[0100] In the embodiments of the present application, the second track mechanism 20 can further include a second screw rod (not shown in the figure). The second screw rod can be connected to the second sliding rail 21 and extend along the X direction, i.e., along the length direction of the second sliding rail 21. Specifically, the second screw rod can be installed in the mounting hole 215 of the second sliding rail 21. At least part of the second screw rod can be exposed through the mounting hole 215 of the first sliding rail 11. The second screw rod can rotate about its central axis relative to the second sliding rail 21. That is, the second screw rod can be rotatably connected to the second sliding rail 21. The extension length of the second screw rod along the X direction can be less than, equal to, or greater than the extension length of the second sliding rail 21 along the X direction. Exemplarily, the second screw rod can be a ball screw rod.

[0101] Please refer to Figure 7 , Figure 8 and Figure 6 , Figure 2 is a structural schematic view of an angle of assembly of the second track mechanism 20 and the sliding mechanism 30 of the vehicle ceiling suction screen device 100 shown in Figure 7 , Figure 2 is a structural schematic view of an angle of the sliding mechanism 30 of the vehicle ceiling suction screen device 100 shown in Figure 8 , Figure 2 is another structural schematic view of an angle of the sliding mechanism 30 of the vehicle ceiling suction screen device 100 shown in Figure 9 .

[0102] The sliding mechanism 30 can be slidably connected to the second sliding rail 21 to realize the sliding connection of the sliding mechanism 30 and the second track mechanism 20. The sliding mechanism 30 can also be sleeved on the second screw rod and can slide along the X direction on the second sliding rail 21 under the driving of the second screw rod. That is, the second screw rod can control the start and stop of the sliding mechanism 30 in the X direction and determine the specific position of the display screen 40 in the X direction.

[0103] It can be understood that by sleeving the sliding mechanism 30 on the second screw rod, the rotational motion of the second screw rod can be converted into the linear motion of the sliding mechanism 30 by using the motion characteristics of the second screw rod, so that the sliding mechanism 30 can be driven by the second screw rod to slide along the X direction on the second sliding rail 21, which is beneficial to reduce the frictional resistance between the sliding mechanism 30 and the second track mechanism 20 and improve the transmission efficiency between the sliding mechanism 30 and the second track mechanism 20.

[0104] The sliding mechanism 30 can include a mounting plate 31, at least two pulleys 32, and at least one second connecting member 33. The mounting plate 31 can be located on a side of the second rail 21 facing away from the first rail mechanism 10 and arranged in a stack with the second rail 21. The mounting plate 31 can slide in the X direction on the second rail 21. The mounting plate 31 can include a mounting surface 311 and a back surface 312. The back surface 312 and the mounting surface 311 can be arranged opposite to each other in the thickness direction (the Z direction shown in the figure) of the mounting plate 31. The back surface 312 can face the second rail mechanism 20, and the mounting surface 311 can face away from the second rail mechanism 20. The mounting plate 31 can be provided with a receiving groove 313. The opening of the receiving groove 313 can be located on the mounting surface 311. The receiving groove 313 can be recessed from the mounting surface 311 to the inside of the mounting plate 31. The receiving groove 313 can be used to accommodate the display screen 40.

[0105] The at least two pulleys 32 can be fixedly connected to the back surface 312 of the mounting plate 31 and located on both sides of the mounting plate 31 in the Y direction. The at least two pulleys 32 are also located in the first sliding groove 216 and the second sliding groove 217 of the second rail 21 and can slide relative to the second rail 21 along the first sliding groove 216 and the second sliding groove 217. That is, the at least two pulleys 32 can be slidingly connected to the second rail 21 to achieve the sliding connection of the second rail mechanism 20 and the two first rails 11. Exemplarily, the number of pulleys 32 can be four. The four pulleys 32 can be arranged at the four corners of the mounting plate 31, respectively. Each pulley 32 can be slidingly connected to one second rail 21. Of course, in some other embodiments, the sliding connection of the sliding mechanism 30 and the second rail mechanism 20 can also be achieved by other means.

[0106] It can be understood that the use of pulleys 32 to achieve the sliding connection between the mounting plate 31 and the second rail 21 not only makes the sliding mechanism 30 have better aesthetic and concealment, i.e., better appearance performance, but also reduces the noise generated when the sliding mechanism 30 slides, so that the sliding mechanism 30 can slide on the second rail mechanism 20 with less noise.

[0107] By slidingly connecting the at least two pulleys 32 to both sides of the second rail 21 in the Y direction, not only can the sliding connection between the mounting plate 31 and the second rail 21 be achieved, but also the installation space of the at least two pulleys 32 can reuse a part of the side space of the second rail 21, effectively reducing the space occupied by the sliding mechanism 30 in the thickness direction of the vehicle ceiling screen device 100, and facilitating the realization of the light and thin vehicle ceiling screen device 100.

[0108] The at least one second connecting member 33 is fixedly connected to the back surface 312 of the mounting plate 31 and is located between the at least two pulleys 32. The at least one second connecting member 33 is sleeved on the second lead screw and is spaced apart from the at least two pulleys 32. The at least one second connecting member 33 can move along the X direction on the second lead screw and drive the at least two pulleys 32 to slide along the X direction on the second sliding rail 21 through the mounting plate 31. That is, the at least one second connecting member 33 can be used to control the start and stop of the sliding mechanism 30 in the X direction. Exemplarily, the number of the first connecting member 23 can be one. The first connecting member 23 is connected to the middle region of the back surface 312 of the mounting plate 31 and is sleeved on the second lead screw. The second connecting member 33 can be driven by the second lead screw to move or stop along the axial direction of the second lead screw.

[0109] It can be understood that, by arranging the second connecting member 33 and movably connecting the second connecting member 33 to the second lead screw, the second connecting member 33 can be driven by the second lead screw to move linearly along the axial direction of the second lead screw when the second lead screw rotates, thereby driving the mounting plate 31 to slide on the second sliding rail 21. The second connecting member 33 can also be controlled by the second lead screw to stop moving linearly along the axial direction of the second lead screw when the second lead screw stops rotating, thereby stopping the mounting plate 31 from sliding on the second sliding rail 21. That is, by the sliding connection of the pulley 32 and the second sliding rail 21 and the movable connection of the second connecting member 33 and the second lead screw, the sliding of the sliding mechanism 30 on the second rail mechanism 20 and the start and stop can be realized.

[0110] Please refer to Figure 10 and Figure 9 , Figure 2 is Figure 10 a schematic diagram of a state of the sliding mechanism 30 of the vehicle ceiling suction screen device 100 shown in Figure 2 is Figure 9 a schematic diagram of another state of the sliding mechanism 30 of the vehicle ceiling suction screen device 100 shown in

[0111] The vehicle ceiling suction screen device 100 can further include a display screen 40. The display screen 40 can be installed on the sliding mechanism 30 and can be driven by the sliding mechanism 30 to move relative to the first rail mechanism 10 along the X direction and / or the Y direction. The display screen 40 can include a camera (not shown in the figure). The camera can be oriented in the same direction as the display surface of the display screen 40 and can enable the display screen 40 to realize one or more of the functions of real-time image acquisition, instant video call, or acquisition of three-dimensional information of a to-be-measured object. The display surface can be the surface that presents information such as text, images, and videos to the passenger when the passenger uses the display screen 40. The camera can serve as a front-facing camera of the display screen 40 to capture still images or dynamic videos in front of the display screen 40.

[0112] The display screen 40 can be mounted in the accommodating groove 313 of the mounting plate 31 of the sliding mechanism 30. The display screen 40 can be of any size that can meet the viewing needs of the user. The camera can be built into the display screen 40, or externally mounted on the outer surface of the display screen 40, or partially located inside the display screen 40 and partially located outside the display screen 40, or any other position that does not affect the display of image information on the display screen 40. For example, the size of the display screen 40 can be 15.6 inches, 17.3 inches, 21.3 inches, 31 inches, etc.

[0113] The display screen 40 can be rotationally connected to the sliding mechanism 30. As shown in Figure 10 , the display screen 40 can be closed relative to the sliding mechanism 30 and accommodated in the sliding mechanism 30. Alternatively, as shown in Figure 11 , the display screen 40 can be opened relative to the sliding mechanism 30 for display. The opening angle of the display screen 40 relative to the sliding mechanism 30 can be selected according to the actual application scenario, and no strict limitation is made.

[0114] It can be understood that by rotationally connecting the display screen 40 to the sliding mechanism 30, the display screen 40 can be opened relative to the sliding mechanism 30 for large-screen display when the display screen 40 is needed, so as to provide more information to the user and provide a better user experience. And when the display screen 40 is not needed, the display screen 40 is accommodated in the sliding mechanism 30, so that the vehicle ceiling screen device 100 has a smaller size, reduces the occupation of the space in the vehicle, expands the visual transparency of the cabin, and brings a better cabin experience.

[0115] The sliding mechanism 30 can further include a rotating shaft mechanism (not shown). The rotating shaft mechanism can be connected between the display screen 40 and the mounting plate 31 to achieve rotational connection of the display screen 40 and the mounting plate 31. The display screen 40 can rotate relative to the mounting plate 31 about at least two rotation center lines. The at least two rotation center lines can include a first rotation center line R1 and a second rotation center line R2. The first rotation center line R1 can be arranged parallel to the Y direction, and the second rotation center line R2 can be arranged parallel to the Z direction.

[0116] It can be understood that by rotating the display screen 40 about the first rotation center line R1, the folding angle of the display screen 40 relative to the sliding mechanism 30 can be controlled, so that the included angle between the display screen 40 and the sliding mechanism 30 is at a comfortable viewing angle of the passenger, which is beneficial to improve the viewing experience comfort of the passenger. And by rotating the display screen 40 about the second rotation center line R2, the circumferential rotation angle of the display screen 40 can be controlled according to different positions of the passenger, so that the display surface of the display screen 40 can face the face of the passenger, and the viewing comfort of the passenger is ensured.

[0117] In a possible implementation, the sliding mechanism 30 can further include a lifting mechanism (not shown in the figure). The lifting mechanism can be connected between the mounting plate 31 and the display screen 40 in a lifting manner, and can be used to drive the display screen 40 to move relative to the sliding mechanism 30 along the Z direction. The moving distance of the display screen 40 relative to the sliding mechanism 30 along the Z direction can be selected according to actual application scenarios, and is not strictly limited.

[0118] It can be understood that, by arranging the lifting mechanism, the display screen 40 can be driven to ascend or descend relative to the mounting plate 31, so as to adjust the distance between the display screen 40 and the passenger in the Z direction, and enable the passenger to better use the display screen 40 for interaction.

[0119] Referring to Figure 11 , Figure 2 is Figure 12 a schematic diagram of a frame structure of a partial structure of the vehicle ceiling suction screen device 100.

[0120] In the embodiment of the present application, the vehicle ceiling suction screen device 100 can further include a driving mechanism 50 and a control unit 60.

[0121] The driving mechanism 50 can be connected with the first track mechanism 10 and the second track mechanism 20. The driving mechanism 50 can be used to drive the second track mechanism 20 to slide along the Y direction on the first track mechanism 10. In this process, the second track mechanism 20 will drive the sliding mechanism 30 to slide along the Y direction synchronously, and the display screen 40 will be driven by the second track mechanism 20 to slide along the Y direction synchronously. The driving mechanism 50 is also used to drive the sliding mechanism 30 to slide along the X direction on the second track mechanism 20. In this process, the display screen 40 will be driven by the second track mechanism 20 to slide along the X direction synchronously. The control unit 60 can be electrically connected with the driving mechanism 50, and is used to control the opening and closing of the driving mechanism 50.

[0122] Exemplarily, the driving mechanism 50 can be connected with the first lead screw 12 of the first track mechanism 10, and can drive the first lead screw 12 to rotate, so as to realize the sliding of the second track mechanism 20 on the first track mechanism 10. The driving mechanism 50 can also be connected with the second lead screw of the second track mechanism 20, and can drive the second lead screw to rotate, so as to realize the sliding of the sliding mechanism 30 on the second track mechanism 20. The control unit 60 can be a control system of the whole vehicle, or a remote controller, etc.

[0123] It can be understood that, by connecting the driving mechanism 50 with the first track mechanism 10 and the second track mechanism 20, the driving mechanism 50 can be used as a power source for the second track mechanism 20 to slide on the first track mechanism 10 and the sliding mechanism 30 to slide on the second track mechanism 20, so that the sliding actions of the second track mechanism 20 and the sliding mechanism 30 can be more smooth and smooth. In addition, the driving mechanism 50 is controlled by the control unit 60, the starting and stopping of the second track mechanism 20 on the first track mechanism 10 and the starting and stopping of the sliding mechanism 30 on the second track mechanism 20 can be controlled, so that the starting and stopping of the display screen 40 in the X direction and the Y direction can be realized, and the reliability is good.

[0124] In the embodiments of the present application, the control unit 60 can be electrically connected with the camera of the display screen 40. The control unit 60 can be used to control the second track mechanism 20 and the sliding mechanism 30 to slide according to the captured image of the camera, so that the display screen 40 is in a preset position. For example, when the number of passengers is one, the preset position of the display screen 40 can be the middle position in front of the passenger. When the number of passengers is two and the two passengers are in the same row, the preset position of the display screen 40 can be the middle position in front of the two passengers.

[0125] When the camera captures the position of the passenger that does not satisfy the best viewing position of the display screen 40, the camera transmits the position information to the control unit 60, and the control unit 60 controls the second track mechanism 20 to slide on the first track mechanism 10 and / or the sliding mechanism 30 to slide on the second track mechanism 20, so as to drive the display screen 40 to move, so that the display screen 40 is in a preset position, and the passenger can interact with the display screen 40 in the best viewing position. When the camera captures the position of the passenger that satisfies the best viewing position of the display screen 40, the camera transmits the position information to the control unit 60, and the control unit 60 controls the second track mechanism 20 to stop sliding on the first track mechanism 10 and / or the sliding mechanism 30 to stop sliding on the second track mechanism 20, and keeps stable hovering.

[0126] It can be understood that, because the camera has a shooting function, it can capture the image of the passenger in front of it to form a captured image. When the position of the passenger's face satisfies the best viewing position of the display screen 40, it can be determined that the passenger is in a good viewing position, and the passenger can have a good use experience. When the position of the passenger's face does not satisfy the best viewing position of the display screen 40, it can be determined that the passenger is in a poor viewing position, and at this time, the position of the display screen 40 needs to be moved to ensure that the passenger's face is always in the best viewing position of the display screen 40.

[0127] The following will exemplarily illustrate the position adjustment process of the display screen 40 and the intelligent experience of the rear-row viewing and entertainment scene by taking the seat rows in the cabin as three rows as an example. The rear row refers to the positions of the second row and the third row when the seat rows are three.

[0128] In the embodiments of the present application, the position adjustment process of the display screen 40 can at least include the following steps:

[0129] First step: Obtain the rear-row personnel information in the cabin. The rear-row personnel information includes the number of passengers in the rear row and the distance between the display screen 40 and the faces of each passenger in the rear row.

[0130] Second step: Obtain the movable path information of the display screen 40 in the cabin according to the rear-row personnel information. The movable path information includes one or more of the passable path of the display screen 40 along the X direction between the first row and the second row, the passable path of the display screen 40 along the Y direction between the first row and the second row, the passable path of the display screen 40 along the X direction between the second row and the third row, and the passable path of the display screen 40 along the Y direction between the second row and the third row.

[0131] Third step: Determine whether the position of the display screen 40 needs to be adjusted according to the movable path information. Specifically, when there is no obstruction in the movable path of the display screen 40 in the cabin, control the display screen 40 to move along the X direction and / or the Y direction so that the display screen 40 is in a preset position. When there is an obstruction in the passable path between the display screen 40 and the passengers, control the display screen 40 not to move (i.e., control the display screen 40 not to adjust the position) and give a voice prompt to remind the passengers that there is an obstruction in the passable path between the display screen 40 and the passengers. When there are multiple rows of passengers in the cabin, the viewing needs of the front-row passengers are given priority.

[0132] In summary, by combining the face position information of the passengers provided by the cabin and the movable path of the display screen 40 in the cabin, the display screen 40 is controlled to move along the X direction and / or the Y direction, which can effectively adjust the distance between the display screen 40 and each passenger in the rear row and make the distance the comfortable viewing distance for different passengers. This not only meets the viewing needs of passengers in different positions, realizes the intelligent adjustment of the optimal viewing position of the display screen 40, and improves the intelligent level of the whole vehicle. It also supports passengers to customize any specific position of the display screen 40, meets the individualized requirements of different passengers, and realizes the intelligent experience of the rear-row viewing and entertainment scene. In addition, by controlling the display screen 40 to move along the X direction and / or the Y direction, the space utilization in the vehicle can also be optimized, and movement interference between the vehicle-mounted ceiling screen device 100 and its surrounding parts, such as the seat, can be avoided.

[0133] For example, different passengers have different viewing needs. Elderly passengers need clear visual effects, child passengers need to adjust their seating height, and visually impaired passengers need more voice assistance prompts. By using the customizable adjustment capability of the in-vehicle ceiling-mounted screen device 100, the display screen 40 can be freely adjusted to any position required by different passengers, meeting their specific viewing position needs.

[0134] The following sections will illustrate the adjustment strategy of the display screen 40 through several application scenarios. Each scenario will be illustrated using an example of a cabin with three rows of seats, two seats in each row, for a total of six seats. In the accompanying drawings, shaded areas indicate seats occupied by passengers.

[0135] Scene 1:

[0136] Please see Figure 12 , Figure 2 yes Figure 13 The diagram shows a simplified illustration of the first application scenario of the vehicle-mounted ceiling screen device 100.

[0137] In this application scenario, there is only one passenger in the second row and no passengers in the third row. When the movable path of the display screen 40 within the cabin is unobstructed, meaning there is a passable path between the display screen 40 and the passenger in the second row, the display screen 40 is controlled to move along the X and / or Y directions to a preset position C, thus completing the position adjustment of the display screen 40. When the movable path of the display screen 40 within the cabin is obstructed, meaning there is no passable path between the display screen 40 and the passenger in the second row, the display screen 40 is not moved and a voice prompt is activated. For example, the preset position C can be the middle position in front of the passenger in the second row.

[0138] Scene 2:

[0139] Please see Figure 13 , Figure 2 yes Figure 14 The diagram shows a simplified illustration of the second application scenario for the vehicle-mounted ceiling-mounted screen device 100.

[0140] In this application scenario, there are two passengers in the second row and no passengers in the third row. When the movable path of the display screen 40 within the cabin is unobstructed, meaning there is a passable path between the display screen 40 and the passengers in the second row, the display screen 40 is controlled to move along the X and / or Y directions to a preset position D, thus completing the position adjustment of the display screen 40. When the movable path of the display screen 40 within the cabin is obstructed, meaning there is no passable path between the display screen 40 and the passengers in the second row, the display screen 40 is not moved and a voice prompt is activated. For example, the preset position D can be the middle position in front of these two passengers.

[0141] Scene 3:

[0142] Please see Figure 14 , Figure 2 yes Figure 15 A simplified schematic diagram of the third application scenario of the vehicle-mounted ceiling screen device 100 shown.

[0143] In this application scenario, there is one passenger in the second row and one in the third row, with the positions of the passenger in the second row and the passenger in the third row offset to each other. The position adjustment of the display screen 40 prioritizes the viewing experience of the passenger in the second row. When the movable path of the display screen 40 within the cabin is unobstructed, i.e., there is a passable path between the display screen 40 and the passenger in the second row, the display screen 40 is controlled to move along the X and / or Y directions to a preset position E, thus completing the position adjustment of the display screen 40. When the movable path of the display screen 40 within the cabin is obstructed, i.e., there is no passable path between the display screen 40 and the passenger in the second row, the display screen 40 is not moved and a voice prompt is activated. For example, the preset position E can be the middle position in front of these two passengers in the second row.

[0144] Scene 4:

[0145] Please see Figure 15 , Figure 2 yes Figure 16 A simplified schematic diagram of the fourth application scenario of the vehicle-mounted ceiling screen device 100 shown.

[0146] In this application scenario, there is one passenger in the second row and two passengers in the third row. The position adjustment of the display screen 40 prioritizes the viewing experience of the passenger in the second row. When the movable path of the display screen 40 within the cabin is unobstructed, meaning there is a passable path between the display screen 40 and the passenger in the second row, the display screen 40 is controlled to move along the X and / or Y directions to a preset position F, thus completing the position adjustment of the display screen 40. When the movable path of the display screen 40 within the cabin is obstructed, meaning there is no passable path between the display screen 40 and the passenger in the second row, the display screen 40 is not moved and a voice prompt is activated. For example, the preset position F can be the middle position of the second row of seats.

[0147] Scene 5:

[0148] Please see Figure 16 , Figure 2 yes Figure 17 The diagram shows a simplified illustration of the fifth application scenario for the vehicle-mounted ceiling-mounted screen device 100.

[0149] In the application scenario, the second row has two passengers, and the third row has one passenger. The position adjustment requirement of the display screen 40 is to give priority to the viewing experience of the two passengers in the second row. When the movable path of the display screen 40 in the cabin is unobstructed, that is, there is a passable path between the display screen 40 and the two passengers in the second row, the display screen 40 is controlled to move in the X direction and / or the Y direction, so that the display screen 40 is in the preset position G, to complete the position adjustment of the display screen 40. When the movable path of the display screen 40 in the cabin is obstructed, that is, there is no passable path between the display screen 40 and the two passengers in the second row, the display screen 40 is controlled not to move and a voice prompt is started. Exemplarily, the preset position G can be the middle position of the two passengers in the second row.

[0150] Scenario six:

[0151] Referring to Figure 17 , Figure 2 is a schematic diagram of a sixth application scenario of the vehicle ceiling suction screen device 100 shown in Figure 18

[0152] In the application scenario, the second row has two passengers, and the third row has two passengers. The position adjustment requirement of the display screen 40 is to give priority to the viewing experience of the two passengers in the second row. When the movable path of the display screen 40 in the cabin is unobstructed, that is, there is a passable path between the display screen 40 and the two passengers in the second row, the display screen 40 is controlled to move in the X direction and / or the Y direction, so that the display screen 40 is in the preset position H, to complete the position adjustment of the display screen 40. When the movable path of the display screen 40 in the cabin is obstructed, that is, there is no passable path between the display screen 40 and the two passengers in the second row, the display screen 40 is controlled not to move and a voice prompt is started. Exemplarily, the preset position H can be the middle position of the two passengers in the second row.

[0153] Scenario seven:

[0154] Referring to Figure 18 , Figure 2 is a schematic diagram of a seventh application scenario of the vehicle ceiling suction screen device 100 shown in Figure 19

[0155] ​​In the application scenario, the second row has no passenger, and the third row has one passenger. When the movable path of the display screen 40 in the cabin is unobstructed, that is, there is a passable path between the display screen 40 and the passenger in the third row, the display screen 40 is controlled to move in the X direction and / or the Y direction, so that the display screen 40 is in the preset position I, to complete the position adjustment of the display screen 40. When the movable path of the display screen 40 in the cabin is obstructed, that is, there is no passable path between the display screen 40 and the passenger in the third row, the display screen 40 is controlled not to move and a voice prompt is started. Exemplarily, the preset position I can be a middle position in front of the passenger in the third row.

[0156] Scenario eight:

[0157] Referring to Figure 19 , Figure 2 is Figure 20 a schematic diagram of an eighth application scenario of the vehicle ceiling screen device 100.

[0158] In the application scenario, the second row has no passenger, and the third row has two passengers. When the movable path of the display screen 40 in the cabin is unobstructed, that is, there is a passable path between the display screen 40 and the two passengers in the third row, the display screen 40 is controlled to move in the X direction and / or the Y direction, so that the display screen 40 is in the preset position J, to complete the position adjustment of the display screen 40. When the movable path of the display screen 40 in the cabin is obstructed, that is, there is no passable path between the display screen 40 and the two passengers in the third row, the display screen 40 is controlled not to move and a voice prompt is started. Exemplarily, the preset position J can be a middle position in front of the two passengers in the third row.

[0159] In the embodiment of the application, the vehicle 200 can further include a sunshade curtain mechanism 230. The sunshade curtain mechanism 230 can be connected to the vehicle body 210 and disposed adjacent to the outer edge of the sunroof glass 220. In sunny weather conditions, the sunshade curtain mechanism can block the sunroof glass 220 and block the direct sunlight from entering the interior of the vehicle 200 through the sunroof glass 220, thereby playing a certain heat-blocking role and providing a comfortable experience for the passengers or the driver. Exemplarily, the sunshade curtain mechanism 230 can be fixed to the vehicle body 210 by means such as bonding, welding, riveting, etc.

[0160] In a possible implementation, referring to Figure 20 , Figure 1 is Figure 21 a schematic diagram of part of the structure of the vehicle 200.

[0161] The sunshade curtain mechanism 230 can include a roller curtain track mechanism 2310 and a roller curtain 2320. The roller curtain track mechanism 2310 is located at the edge of the sunroof glass 220. The roller curtain track mechanism 2310 can extend along the length direction of the sunroof glass 220, i.e., along the Y direction. The roller curtain 2320 is wound on the roller curtain track mechanism 2310 and can move along the Y direction under the drive of the roller curtain track mechanism 2310, so as to cover or expose the sunroof glass 220. The first track mechanism 10 can be located between the edge of the sunroof glass 220 and the roller curtain track mechanism 2310. That is, the first track mechanism 10 can be closer to the edge of the sunroof glass 220 relative to the roller curtain track mechanism 2310.

[0162] In another possible implementation, referring to Figure 21 , Figure 1 is ​ another schematic diagram of the partial structure of the vehicle 200.

[0163] Different from the previous implementation, the sunshade curtain mechanism 230 can include the first track mechanism 10 and the roller curtain 2320. The roller curtain 2320 is wound on the first track mechanism 10 and can move along the Y direction under the drive of the first track mechanism 10, so as to cover or expose the sunroof glass 220.

[0164] It can be understood that multiplexing the track in the first track mechanism 10 as the track of the sunshade curtain mechanism 230 can make the first track mechanism 10 have the dual functions of winding the roller curtain 2320 and providing the slide for the second track mechanism 20, which is conducive to the multifunctionalization of the first track mechanism 10 and improves the space utilization, the aesthetic and concealment of the structure in the vehicle 200.

[0165] The above is only part of the embodiments and implementations of the present application, and the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
