Description

Technical Field

[0001] This application relates to the field of display device technology, and more particularly to a ceiling-mounted screen structure and an automobile. Background Technology

[0002] Ceiling-mounted displays are a common type of display device used in automotive environments. They are typically installed on the ceiling of the vehicle and can switch between a recessed and an open state to meet viewing needs in different usage scenarios. As users' requirements for viewing angles and comfort increase, ceiling-mounted displays need to have a wide opening angle to support diverse usage methods such as lying down.

[0003] Currently, there are ceiling-mounted screen structures on the market that achieve a large opening angle by increasing the gap between the display screen and the interior trim, and then using a shielding component to cover the gap. However, the display screen is prone to contact with the shielding component during the opening process, resulting in scratches. Therefore, how to reduce the probability of display screen scratches is one of the issues that the industry needs to study. Summary of the Invention

[0004] This application provides a ceiling-mounted screen structure and a car that can reduce the probability of scratches on the display screen.

[0005] The technical solution of this application embodiment is implemented as follows: The first aspect of this application provides a ceiling-mounted screen structure, comprising: a base structure having a mounting groove; a display screen, one end of which serves as a rotating connection end, the display screen being rotatably connected to the base structure via the rotating connection end, the display screen being able to reciprocate between a retracted position and a maximum open position, wherein in the retracted position the display screen is accommodated within the mounting groove, and a first gap exists between the end face of the rotating connection end and the side wall of the mounting groove, and in the maximum open position a portion of the display screen extends out of the mounting groove; a blocking member movably connected to the base structure, wherein when the display screen is in the retracted position, the blocking member blocks at least a portion of the first gap at the opening of the mounting groove; and a transmission assembly disposed on the base structure and connected to the blocking member, the transmission assembly being configured to drive the blocking member to avoid the display screen during the rotation of the display screen from the retracted position to the maximum open position, thereby creating a gap between the blocking member and the display screen.

[0006] In some embodiments, the transmission assembly includes a plurality of transmission members connected in sequence. The plurality of transmission members include a first transmission member and a second transmission member arranged adjacent to each other along the transmission direction. The display screen can also rotate to a first transition position, which is located between a retracted position and a maximum open position. During the process of the display screen rotating from the retracted position to the first transition position, the first transmission member and the second transmission member disengage from each other, and the blocking member blocks at least a portion of the first gap. During the process of the display screen rotating from the first transition position to the maximum open position, the first transmission member and the second transmission member are connected in transmission to drive the blocking member to rotate and avoid the display screen.

[0007] In some embodiments, of the first transmission member and the second transmission member, one is a full-tooth gear and the other is a toothed gear. The outer circumference of the full-tooth gear is formed with first teeth, and a portion of the outer circumference of the toothed gear is formed with second teeth, while the remaining portion is toothless. The first teeth can mesh with the second teeth.

[0008] In some embodiments, the toothed gear is toothless along a quarter of its outer circumference.

[0009] In some embodiments, the ceiling-mounted screen structure further includes a driving component connected to the base structure and driven by the display screen, which can drive the display screen to rotate. One end of the transmission component is connected to the output end of the driving component, and the other end is connected to the shielding component. The transmission component can drive the shielding component to avoid the display screen under the action of the driving component.

[0010] In some embodiments, the transmission assembly includes a first transmission shaft connected to the display screen and the output end of the drive component, which is capable of rotating under the action of the drive component and driving the display screen to rotate.

[0011] In some embodiments, the transmission assembly further includes a first gear, a second gear, and a third gear. The first gear is connected to a first transmission shaft. The first gear is a toothed gear, with teeth formed on a portion of its outer circumference and no teeth on the remaining portion. The second and third gears are both full-tooth gears and mesh with each other. The outer circumferences of the full-tooth gears are all formed with teeth. The teeth of the first gear can mesh with the teeth of the second gear. The third gear is connected to a shielding member.

[0012] In some embodiments, the transmission assembly further includes a second transmission shaft rotatably connected to the base structure, and the third gear and the shielding member are both rotatably connected to the second transmission shaft.

[0013] In some embodiments, the display screen is rotatably connected to the base structure about a first rotational axis, and the shielding member is rotatably connected to the base structure about a second rotational axis, with the first and second rotational axes arranged parallel to each other.

[0014] In some embodiments, two transmission components are provided, with the two transmission components respectively located on opposite sides of the shield. A second aspect of this application provides an automobile that includes the ceiling-mounted screen structure provided in the first aspect.

[0015] The embodiments of this application have the following beneficial effects: In the embodiments of this application, when the display screen is in the retracted position, it is housed within the mounting slot, and the shielding member covers at least a portion of the first gap, improving aesthetics. When in the fully open position, a portion of the display screen extends beyond the mounting slot to meet the user's need for wide-angle viewing. Furthermore, during the rotation of the display screen from the retracted position to the fully open position, the transmission component can drive the shielding member to avoid the display screen, ensuring a gap between the shielding member and the display screen throughout the process. This prevents direct contact between the shielding member and the display screen, effectively reducing the risk of scratches and pinched fingers. Attached Figure Description

[0026] The following is a detailed description of this application.

[0027] Ceiling-mounted displays are a common type of display device used in automotive environments. They are typically installed on the ceiling of the vehicle and can switch between a recessed and an open state to meet viewing needs in different usage scenarios. As users' requirements for viewing angles and comfort increase, ceiling-mounted displays need to have a wide opening angle to support diverse usage methods such as lying down.

[0028] Currently, there are ceiling-mounted screen structures on the market that achieve a large opening angle by increasing the gap between the display screen and the interior trim, and then using a shielding component to cover the gap. These structures often use a method where the shielding component physically contacts the display screen to push it open, which can easily cause scratches between the shielding component and the display screen.

[0029] To address this issue, the inventors of this application have designed a ceiling-mounted screen structure. When the display screen is in the retracted position, the shielding component can block the gap. Furthermore, during the opening process, the shielding component can be driven by a transmission component to avoid the display screen. Throughout the opening process, there is always a gap between the shielding component and the display screen, preventing them from contacting each other and thus significantly reducing the scratching problem between the shielding component and the display screen.

[0030] The following is in conjunction with the appendix Figures 1 to 7 Some embodiments of this application will be described in detail.

[0031] Figure 1 A three-dimensional structural diagram of a ceiling-mounted screen structure according to one or more embodiments when the display screen is in the retracted position; Figure 2 This is a three-dimensional exploded structural diagram of a ceiling-mounted screen structure according to one or more embodiments; Figure 3 This is another exploded perspective view of a ceiling-mounted screen structure according to one or more embodiments; Figure 4 This is a front view of the display screen structure according to one or more embodiments when it is in a first transition position; Figure 5 This is a front view of the ceiling-mounted screen structure according to one or more embodiments when the display screen is in its maximum open position; Figure 6 A three-dimensional structural diagram of a ceiling-mounted screen structure according to one or more embodiments, with the interior panel removed; Figure 7 for Figure 6 Enlarged view of point A in the middle.

[0032] In some embodiments of this application, for ease of explanation, a first direction, a second direction, and a third direction are defined. These three directions intersect each other; here, intersecting includes perpendicularly intersecting. For ease of understanding of the embodiments of this application, an example is given where the first direction, second direction, and third direction intersect each other perpendicularly. However, those skilled in the art should understand that the embodiments of this application are not limited to the case where these three directions intersect each other perpendicularly. For ease of explanation, as... Figure 6 As shown by the arrows, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the third direction. In some cases, when the ceiling screen structure 100 is installed on the roof of the vehicle, the direction pointed to by arrow Z is called downward, and the direction opposite to the direction pointed to by arrow Z is called upward.

[0033] like Figures 1 to 5As shown, an embodiment of this application provides a ceiling-mounted screen structure 100, which includes a base structure 1, a display screen 2, a shielding member 3, and a transmission assembly 4. The base structure 1 has a mounting groove 10. One end of the display screen 2 serves as a rotating connection end 21, and the display screen 2 is rotatably connected to the base structure 1 through the rotating connection end 21. The display screen 2 can reciprocate between a retracted position and a fully open position. When in the retracted position, the display screen 2 is accommodated within the mounting groove 10, and the end face of the rotating connection end 21 is flush with the side wall of the mounting groove 10. The display screen 2 has a first gap 101, and when it is in the extreme open position, a portion of the display screen 2 extends out of the mounting groove 10; the shielding member 3 is movably connected to the base structure 1, and when the display screen 2 is in the retracted position, the shielding member 3 blocks at least a portion of the first gap 101 at the opening of the mounting groove 10; the transmission component 4 is disposed on the base structure 1 and connected to the shielding member 3, and the transmission component 4 is configured to drive the shielding member 3 to avoid the display screen 2 during the process of the display screen 2 rotating from the retracted position to the extreme open position, so that there is a gap between the shielding member 3 and the display screen 2.

[0034] The retracted position refers to the position of the display screen 2 when it is housed in the mounting slot 10 of the base structure 1. In this position, the screen of the display screen 2 faces inwards into the slot. The display screen 2 does not affect the use of external space and the obstruction member 3 blocks the external gap (first gap 101). The obstruction member 3 can completely block the first gap 101. For example, the obstruction member 3 can be offset from the display screen 2 towards the outside of the slot opening of the mounting slot 10 and projected along a direction perpendicular to the plane of the slot opening. The orthographic projection of the obstruction member 3 overlaps with the orthographic projection of the display screen 2. Thus, the obstruction member 3 has a gap from the display screen 2 while completely blocking the first gap 101. Alternatively, the obstruction member 3 can partially block the first gap 101. For example, the outer surface of the obstruction member 3 can be coplanar with the outer surface of the display screen 2, and there can be a gap between them. This gap is significantly smaller than the size of the first gap 101, making it less likely to affect the appearance and less likely to cause scratches to the display screen 2.

[0035] The maximum open position refers to the position where the display screen 2 is fully extended from the retracted position to its maximum angle. In this state, the display screen 2 can achieve a wide viewing angle. At the same time, the blocking member 3 avoids the display screen 2, and there is a gap between the two. The angle between the display screen 2 in the maximum open position and the retracted position can be greater than 90° and less than 180°. For example, the angle between the display screen 2 in the maximum open position and the retracted position can be, but is not limited to, 160°. Of course, other angles are also possible, and no specific limitation is made here.

[0036] The shielding component 3 is a part movably mounted on the base structure 1, used to shield the gap between the end face of the rotating connection end 21 of the display screen 2 and the side wall of the mounting groove 10, thereby improving the appearance and preventing the risk of pinching fingers. During the rotation of the display screen 2 to its maximum open position, the shielding component 3, under the action of the transmission assembly 4, avoids direct contact between the shielding component 3 and the display screen 2, reducing scratches or abnormal noises caused by direct contact. The movement of the shielding component 3 to avoid the display screen 2 can include rotational movement or translational movement, as long as it avoids the display screen 2, ensuring a gap between the display screen 2 and the shielding component 3. For example, the shielding component 3 can be a thin plastic sheet or a metal sheet.

[0037] The transmission component 4 refers to a set of transmission structures located on the base structure 1 and connected to the shielding member 3. During the rotation of the display screen 2 between the retracted position and the extreme open position, the transmission component 4 can drive the shielding member 3 to move, so that it always maintains a distance from the display screen 2.

[0038] The base structure 1 refers to the fixed part of the entire ceiling-mounted screen structure 100 used to support the display screen 2, the shielding member 3, and the transmission assembly 4. The base structure 1 is usually made of metal or high-strength plastic and has high structural stability. For example, the base structure 1 can be an integrated bracket structure, with a mounting groove 10 formed on one surface of the bracket structure. For example, the base structure 1 includes a base 11 and an interior panel 12. The base 11 can be embedded into the interior of the car roof, and the interior panel 12 is disposed on the outside of the base 11. The interior panel 12 has a through groove, which, together with the base 11, forms the mounting groove 10. Thus, the opening at the end of the through groove away from the base 11 is the opening of the mounting groove 10.

[0039] The mounting slot 10 refers to the storage space reserved in the base structure 1 for the display screen 2. When the display screen 2 is in the retracted position, it is stored in the mounting slot 10, thus achieving a concealed appearance. For example, in the roof area above the car seat, the mounting slot 10 can be rectangular or arc-shaped to adapt to the interior design of different car models. The mounting slot 10 can also be equipped with guide surfaces or limiting structures to improve the stability of the display screen 2 during rotation. The mounting slot 10 can also be equipped with a positioning structure, which fixes the position of the display screen 2 when it is stored in the mounting slot 10, reducing the possibility that the display screen 2 may fall out of the mounting slot 10 due to the shaking of the car during driving.

[0040] Rotary connection end 21 is one end of display screen 2. Rotary connection end 21 is rotatably connected to base structure 1 to realize the rotatable connection between display screen 2 and base structure 1. In this way, the rotation center axis of display screen 2 (the first rotation center axis in the following text) approaches or passes through rotary connection end 21. The other end of display screen 2 opposite to rotary connection end 21 is the part that sweeps through the longest path during the flipping process of display screen 2.

[0041] In the embodiments of this application, when the display screen 2 is in the retracted position, it is housed within the mounting groove 10, and the shielding member 3 blocks at least a portion of the first gap 101, improving aesthetics. When in the fully open position, a portion of the display screen 2 extends beyond the mounting groove 10 to meet the user's need for a wide viewing angle. For example, above the rear seat of a car, when a passenger lies down to watch a movie, the display screen 2 can rotate to a near-horizontal position, thereby achieving a wider field of view. Furthermore, during the rotation of the display screen 2 from the retracted position to the fully open position, the transmission component 4 can drive the shielding member 3 to avoid the display screen 2, ensuring a gap between the shielding member 3 and the display screen 2 throughout the process, preventing direct contact between the shielding member 3 and the display screen 2, thereby effectively reducing the risk of scratches and pinching.

[0042] In some embodiments, such as Figures 5 to 7 As shown, the transmission assembly 4 includes multiple transmission components connected in sequence. The multiple transmission components include a first transmission component 41 and a second transmission component 42 arranged adjacent to each other along the transmission direction. The display screen 2 can also rotate to a first transition position, which is located between the retracted position and the extreme open position. During the process of the display screen 2 rotating from the retracted position to the first transition position, the first transmission component 41 and the second transmission component 42 disengage from each other, and the blocking component 3 blocks at least a portion of the first gap 101. During the process of the display screen 2 rotating from the first transition position to the extreme open position, the first transmission component 41 and the second transmission component 42 are connected in transmission to drive the blocking component 3 to rotate and avoid the display screen 2.

[0043] It is understood that the first transition position is one of the positions of the display screen 2 during its rotation between the retracted position and the maximum open position, for example, such as... Figure 4 As shown, the first transition position is a position perpendicular to the display screen 2 when it is in the retracted position. When the display screen 2 is in the position between the retracted position and the first transition position, the blocking member 3 remains stationary in the initial position of blocking the first gap 101 and will not contact the display screen 2. In this stage, the blocking member 3 does not need to avoid the display screen 2. However, when the display screen 2 is in the position between the first transition position and the maximum open position, the opening angle of the display screen 2 is larger, and the display screen 2 is more likely to contact the blocking member 3. Therefore, in this stage, the blocking member 3 is set to avoid the display screen 2 by moving.

[0044] For example, the angle between the display screen 2 in the retracted position and the first transition position can be, but is not limited to, 90°.

[0045] It should be noted that transmission component 4 includes, but is not limited to, gear transmission components, belt transmission components, etc.

[0046] With this configuration, when the first transmission member 41 and the second transmission member 42 are connected, the transmission motion in the transmission assembly 4 is continuous, allowing the blocking member 3 to avoid the movement of the display screen 2. When the first transmission member 41 and the second transmission member 42 are disengaged, the transmission motion of the transmission assembly 4 is blocked, preventing it from transmitting motion to the blocking member 3. Therefore, when the display screen 2 is opened at a small angle, the blocking member 3 can remain stationary, continuing to block the first gap 101. Conversely, when the display screen 2 is opened at a large angle, the transmission assembly 4 transmits motion to the blocking member 3, causing the blocking member 3 to avoid the display screen 2. This phased control method better adapts to the blocking requirements of the display screen 2 in different opening and closing states, more effectively blocking the gap and further improving aesthetics.

[0047] Of course, the movement of the blocking member 3 is not limited to stages. In some embodiments, the blocking member 3 can perform avoidance movement throughout the entire process of the display screen 2 opening.

[0048] In some embodiments, of the first transmission member 41 and the second transmission member 42, one is a full-tooth gear and the other is a toothed gear. The outer circumference of the full-tooth gear is formed with teeth, and a portion of the outer circumference of the toothed gear is formed with teeth, while the remaining portion is toothless. The teeth of the toothed gear can mesh with the teeth of the full-tooth gear.

[0049] Understandably, during the rotation of the display screen 2 from the retracted position to the first transition position, the teeth of the full-tooth gear disengage from the teeth of the missing-tooth gear; that is, the full-tooth gear and the missing-tooth gear are not meshed, and no motion is transmitted between them. During this stage, the position of the blocking member 3 is the same as when the display screen 2 is in the retracted position, and the blocking member 3 blocks at least a portion of the first gap 101. During the rotation of the display screen 2 from the first transition position to the ultimate open position, the first transmission member 41 and the second transmission member 42 are connected, that is, the teeth of the full-tooth gear mesh with the teeth of the missing-tooth gear, and can transmit motion toward the blocking member 3, so that the blocking member 3 avoids the display screen 2.

[0050] Thus, by using a combination of missing-tooth gears and full-tooth gears, the transmission component 4 achieves the function of intermittently transmitting motion by engaging within a specific angular range and disengaging within other angular ranges. This setting allows for precise control of the activation timing of the shielding component 3, ensuring that it only begins to avoid obstacles after the display screen 2 reaches a certain angle, thereby improving the accuracy and coordination of the shielding plate 31's movement and reducing unnecessary friction and wear.

[0051] Of course, it is understood that the transmission component 4 for intermittent motion transmission is not limited to a combination of a toothed gear and a full-toothed gear. In some embodiments, a device for driving the first transmission member 41 or the second transmission member 42 to shift can also be provided, for example, the two can be connected in transmission during the phase when motion transmission is required, and one of them can be moved to a different position and disengaged from the other during the phase when motion transmission is not required.

[0052] In some embodiments, such as Figure 7 As shown, the outer quarter of the toothed gear has no teeth, while the remaining three-quarters has teeth.

[0053] For example, such as Figure 7 As shown, the first transmission component 41 is a toothed gear, and the second transmission component 42 is a full-tooth gear.

[0054] It is understandable that the central angle corresponding to the toothless part of the toothed gear is 90°, which prevents the display screen 2 from transmitting movement to the blocking member 3 through the transmission component 4 within the rotation range of 0° to 90°. 0° to 90° represents the position of the display screen 2 and the angle it has rotated when it is in the retracted position.

[0055] Thus, during the rotation of the display screen 2 from the retracted position to the first transition position, the toothless part of the missing tooth gear is opposite to the full tooth gear, that is, the missing tooth gear and the full tooth gear are not meshed. Since a quarter of the outer circumference of the missing tooth gear is toothless, the transmission component 4 does not transmit motion to the shielding member 3 during the rotation of the display screen 2 from 0° to 90°. During this process, the shielding member 3 does not rotate and remains in the state of blocking the first gap 101. As the display screen 2 continues to rotate from the first transition position (at the 90° position) to the extreme open position at a larger angle, the teeth of the missing tooth gear mesh with the teeth of the full tooth gear, driving the shielding member 3 to rotate and avoid the display screen 2. Therefore, the shielding member 3 can block the first gap 101 as much as possible, improving the aesthetics, and when the shielding member 3 and the display screen 2 are about to contact, the shielding member 3 will avoid direct contact with the display screen 2.

[0056] In some embodiments, such as Figure 7 As shown, the ceiling-mounted screen structure 100 also includes a driving component 5, which is connected to the base structure 1 and driven to drive the display screen 2, and can drive the display screen 2 to rotate. One end of the transmission component 4 is driven to the output end of the driving component 5, and the other end is connected to the shielding component 3. The transmission component 4 can drive the shielding component 3 to avoid the display screen 2 under the action of the driving component 5.

[0057] The drive component 5 can be, but is not limited to, a rotary motor, a rotary cylinder, etc.

[0058] In this way, by linking the drive component 5 with the transmission component 4, the avoidance action of the shield 3 is uniformly controlled by the drive component 5, thereby realizing the coordinated movement of the display screen 2 and the shield 3, improving the accuracy and consistency of the action, and further reducing the possibility of scratches on the display screen 2 and the shield 3.

[0059] Of course, it is understood that the ceiling-mounted screen structure 100 is not limited to setting the driving component 5. In some embodiments, the ceiling-mounted screen structure 100 may not set the driving component 5. The display screen 2 can be rotated by manually turning it. During the rotation of the display screen 2, the transmission component 4 can transmit the rotational movement of the display screen 2 toward the baffle plate 31, thereby driving the baffle plate 31 to avoid the movement of the display screen 2.

[0060] In some embodiments, such as Figure 7 As shown, the transmission assembly 4 includes a first transmission shaft 44, which is connected to the display screen 2 and the output end of the drive component 5. It can rotate under the action of the drive component 5 and drive the display screen 2 to rotate.

[0061] For example, the first drive shaft 44 is rotatably connected to the base structure 1 around its own central axis and can rotate around its own central axis under the action of the drive member 5.

[0062] It is understandable that the first drive shaft 44 belongs to the transmission assembly 4, that is, the first drive shaft 44 has the function of transmitting motion to the shielding member 3.

[0063] Thus, the first drive shaft 44 has the function of transmitting motion to the display screen 2 and the function of transmitting motion to the shielding component 3, thereby reducing the number of parts, reducing space occupation, and facilitating the miniaturization of the ceiling screen structure 100.

[0064] Of course, the transmission assembly 4 is not limited to including the first drive shaft 44. In some embodiments, the transmission assembly 4 does not include the first drive shaft 44, and the output end of the drive member 5 can be directly connected to the display screen 2.

[0065] In some embodiments, such as Figure 7 As shown, the transmission assembly 4 also includes a first gear 41a, a second gear 42a, and a third gear 43. The first gear 41a is connected to the first transmission shaft 44. The first gear 41a is a toothed gear, with teeth formed on the outer circumference of the toothed gear and no teeth on the remaining part. The second gear 42a and the third gear 43 are both full-tooth gears and mesh with each other. The outer circumference of the full-tooth gears is formed with teeth. The teeth of the first gear can mesh with the teeth of the second gear. The third gear 43 is connected to the shielding member 3.

[0066] For example, the first gear 41a is connected to the first drive shaft 44 and shares a central axis.

[0067] For example, one-quarter of the outer circumference of a toothed gear is toothless, while the remaining three-quarters has teeth.

[0068] Thus, by setting different types of gear combinations, multi-stage transmission control is achieved between the drive component 5, the display screen 2, and the shielding component 3, enabling intermittent transmission of motion to the shielding component 3. Moreover, by setting three gears, the number of gears is reduced, and the space occupied is small. In addition, the mechanical fixation of the shielding component 3 by the gear combination helps to reduce the shaking of the shielding component 3, thereby reducing abnormal noises caused by collisions with surrounding components on bumpy roads.

[0069] Of course, it is understood that the transmission assembly 4 is not limited to having only three gears, but can also have four, five, or other numbers of gears. It is not limited to setting the first gear 41a as a toothed gear; in some embodiments, the third gear 43 can be set as a toothed gear.

[0070] In some embodiments, such as Figure 7 As shown, the transmission assembly 4 also includes a second transmission shaft 45, which is rotatably connected to the base structure 1. The third gear 43 and the shielding member 3 are both rotatably connected to the second transmission shaft 45.

[0071] For example, the second drive shaft 45 is rotatably connected to the base structure 1 about its own central axis.

[0072] For example, the shielding member 3 includes a shielding plate 31 and a connecting part 32 connected to the shielding plate 31. The second drive shaft 45 passes through the upright plate of the base 11, and the two ends of the second drive shaft 45 are respectively connected to the third gear 43 and the connecting part 32 of the shielding member 3.

[0073] Thus, the rotational motion of the third gear 43 is transmitted to the blocking member 3 through the second transmission shaft 45, realizing the synchronous rotation of the third gear 43 and the blocking member 3. Moreover, the blocking member 3 is rotatably connected to the base structure 1 through the second transmission shaft 45, which improves the controllability of the movement trajectory of the blocking member 3 and improves the accuracy and stability of the overall structure.

[0074] Of course, it is understood that the transmission assembly 4 is not limited to including the second transmission shaft 45. In some embodiments, the transmission assembly 4 does not include the second transmission shaft 45, and the third gear 43 is directly connected to the shield 3.

[0075] In some embodiments, such as Figure 4 and Figure 5 As shown, the shielding component 3 is rotatably connected to the base structure 1, and the shielding component 3 avoids the display screen 2 by rotating.

[0076] For example, such as Figure 7As shown, the shielding member 3 is rotatably connected to the base structure 1 via the second transmission shaft 45.

[0077] See Figure 4 When the display screen 2 is in the first transition position, the blocking member 3 still does not avoid the display screen and remains in the initial position of blocking the first gap 101. As it continues to rotate along the opening rotation direction C, the blocking member 3 begins to rotate along the opening rotation direction C to avoid the display screen 2. When the display screen 2 rotates to... Figure 5 When the shielding part 3 is in the extreme open position shown, it also rotates to its maximum angle.

[0078] In this way, the avoidance of the blocking component 3 is achieved by rotation, which saves more space than translation and has a compact structure, making it suitable for scenarios with limited installation space. At the same time, the rotational motion is also easier to coordinate with other transmission components to achieve the coordinated execution of complex actions.

[0079] Of course, it is understood that the shielding member 3 is not limited to being rotatably connected to the base structure 1. In some embodiments, the shielding member 3 and the base structure 1 can be relatively translatably connected.

[0080] In some embodiments, such as Figure 4 and Figure 5 As shown, the display screen 2 is rotatably connected to the base structure 1 around the first rotation center axis, and the shielding member 3 is rotatably connected to the base structure 1 around the second rotation center axis. The first rotation center axis and the second rotation center axis are arranged parallel to each other.

[0081] For example, such as Figure 7 As shown, the display screen 2 is connected to the output end of the drive component 5 via a first drive shaft 44, the central axis of which is the first rotational central axis. The shielding component 3 is rotatably connected to the base structure 1 via a second drive shaft 45, the central axis of which is the second rotational central axis.

[0082] In this way, by setting mutually parallel rotation center axes, the rotation trajectories of the display screen 2 and the shielding component 3 do not interfere with each other, while improving the stability of the relative positional relationship between the two, reducing the occurrence of jamming or interference, and improving the overall structural coordination and operating efficiency.

[0083] Of course, the first rotation center axis and the second rotation center axis are not limited to being parallel. In some embodiments, the first rotation center axis and the second rotation center axis are not parallel.

[0084] In some embodiments, such as Figure 6 As shown, there are two transmission components 4, which are respectively located on opposite sides of the shield 3.

[0085] For example, such as Figure 6As shown, the extension direction of the first rotation center axis and the second rotation center axis is the first direction X. One end of the display screen 2 along the second direction Y serves as the rotation connection end 21. The slot of the mounting groove 10 faces the third direction Z. The first direction X, the second direction Y, and the third direction Z intersect each other. The two transmission components 4 are respectively set on opposite sides of the shielding member 3 along the first direction X.

[0086] For example, such as Figure 6 and Figure 7 As shown, a drive member 5 is provided on one side of the display screen 2 along the first direction X. The drive member 5 is connected to the first drive shaft 44 of the transmission assembly 4 on that side. The transmission assembly 4 on the other side is not equipped with a drive member 5. That is, the first drive shaft 44 of the transmission assembly 4 on the other side is rotatably connected to the base structure 1 around its own central axis, and the first drive shaft 44 is fixedly connected to the display screen 2.

[0087] For example, the first drive shaft 44 and the second drive shaft 45 of the two transmission assemblies 4 located on opposite sides share a common central axis. The structures of the corresponding transmission components of the two transmission assemblies 4 located on opposite sides are substantially the same.

[0088] Thus, by setting transmission components 4 on both sides of the shield 3, the force balance of the shield 3 during rotation is achieved, avoiding excessive force on one side that could lead to deformation or damage, improving structural strength and service life, and also contributing to the smoothness and consistency of the shield 3's movement.

[0089] Embodiments of this application also provide a car including any of the above-described ceiling-mounted screen structures 100.

[0090] The car body forms a passenger compartment, and the ceiling-mounted screen structure 100 is installed on the ceiling of the passenger compartment. For example, the base 11 is embedded in the interior of the ceiling, and the interior panel 12 is disposed on the outside of the base 11, flush with the inner surface of the passenger compartment ceiling.

[0091] In this way, the display screen 2 of the ceiling-mounted screen structure 100 used in the car is not easily scratched, not easily pinched, and does not easily make abnormal noises.

[0092] The following is a brief description of the movement of each component in the ceiling-mounted screen structure 100 provided in this application embodiment during the opening and closing of the display screen 2.

[0093] First, the opening process.

[0094] During the rotation of the display screen 2 from the retracted position to the fully open position, the drive component 5 drives the display screen 2 to rotate outward via the first transmission shaft 44. Before the display screen 2 rotates to the first transition position, the teeth of the first gear 41a are not engaged with the teeth of the second gear 42a, that is, they are in a disengaged state, and the motion cannot be transmitted to the blocking component 3. During this stage, the blocking component 3 is stationary and remains in the initial position of blocking the first gap 101. When the drive component 5 drives the display screen 2 through the first transition position, the teeth of the first gear 41a are about to engage with the teeth of the second gear 42a. After the drive component 5 drives the display screen 2 through the first transition position, the teeth of the first gear 41a and the teeth of the second gear 42a have engaged. Thus, the rotational motion of the first transmission shaft 44 is transmitted to the blocking component 3 in sequence through the first gear 41a, the second gear 42a, the third gear 43, and the second transmission shaft 45, causing the blocking component 3 to rotate in the same direction as the rotation of the display screen 2, thereby avoiding the display screen 2 and creating a gap between the display screen 2 and the blocking component 3.

[0095] Second, the opening process.

[0096] During the rotation of the display screen 2 from the fully open position to the retracted position, the drive member 5 drives the display screen 2 to rotate toward the mounting groove 10 via the first transmission shaft 44. Before the display screen 2 rotates to the first transition position, the teeth of the first gear 41a mesh with the teeth of the second gear 42a, that is, the motion can be transmitted to the blocking member 3. Therefore, during this stage, as the display screen 2 rotates, the blocking member 3 also rotates toward the mounting groove 10. When the drive member 5 drives the display screen 2 past the first transition position, the blocking member 3 has rotated to the initial position of blocking the first gap 101, and the teeth of the first gear 41a are about to disengage from the teeth of the second gear 42a. After the drive member 5 drives the display screen 2 past the first transition position, the teeth of the first gear 41a and the teeth of the second gear 42a have disengaged. Thus, during this stage, the display screen 2 rotates, and the blocking member 3 remains stationary, maintaining the initial position of blocking the first gap 101, until the display screen 2 rotates to the retracted position housed in the mounting groove 10.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
