Description

Technical Field

[0001] This utility model relates to the field of vehicle interior display technology, and in particular to a rear-seat ceiling-mounted display device for vehicles. Background Technology

[0002] Currently, traditional single-axis ceiling-mounted screens have several design limitations, making it difficult to adapt to diverse user needs: First, the display surface faces the roof by default, and the display function is only available when the screen is fully open, directly limiting the use of the ceiling-mounted screen in camping mode and double bed mode. Second, the motor and pivot are positioned too far forward, limiting the size of the rear sunroof opening while ensuring the same viewing distance for passengers. The distance between the screen display surface and the sunroof opening exceeds 350mm, affecting the sense of openness and user experience in the rear space. Third, the maximum opening angle of the ceiling-mounted screen is limited, generally less than 120 degrees. However, current zero-gravity seats and large-angle seats require the ceiling-mounted screen to be positioned so that the user's line of sight is perpendicular to the screen display surface, i.e., the reference standard is the seat angle + 80° min. The traditional single-axis structure cannot meet this adaptation requirement.

[0003] Current technology uses a multi-link design to achieve the requirement of a downward-facing roof-mounted screen, but this design currently produces noise levels exceeding 43dB, failing to meet the 35dB requirement. Furthermore, the screen opening position in the multi-link design is located in the middle of the bracket assembly, which also affects the size of the rear sunroof opening. In addition, the multi-link design is more expensive. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0018] A rear-seat ceiling-mounted display device for fixing a display screen 2 to the top of a vehicle includes a bracket assembly 1, a display screen 2, a modular drive unit 3, an eccentric rotating shaft assembly 4, and a shielding cover 5.

[0019] The bracket assembly 1 is connected to the vehicle roof via fasteners. In this preferred embodiment, the bracket assembly 1 is made of die-cast aluminum alloy and is connected to the vehicle roof sheet metal via four sets of bolts.

[0020] The display screen 2 is movably connected to the bracket assembly 1, and the display surface of the display screen 2 faces downwards when closed. Preferably, in this embodiment, by inverting the display screen 2 so that the display surface faces downwards, the user can view the screen even when it is closed. Furthermore, the distance between the display screen 2 and the vehicle sunroof opening is less than 150mm. The display screen 2 can support a movement angle of 90~180 degrees, accommodating the needs of zero-gravity seats and seats with large-angle adjustments. Furthermore, heat dissipation fins can be provided on the back of the display screen 2. Furthermore, the movement angle of the display screen 2 is adjustable.

[0021] The modular drive unit 3 includes a position sensor 31 and a drive motor 32. The modular drive unit 3 is detachably mounted to one side of the bracket assembly 1 by screws. In this embodiment, the modular drive unit 3 is preferably arranged on one side of the bracket assembly 1, that is, near the rear of the vehicle, to ensure that the ceiling-mounted screen assembly has minimal impact on the size of the rear sunroof opening.

[0022] The first end of the eccentric rotating shaft assembly 4 is fixedly connected to the output shafts of the position sensor 31 and the drive motor 32 respectively via bearings, and the second end is connected to the back of the display screen 2 via screws.

[0023] The shielding cover 5 is fixed to the rotating side of the display screen 2. In this embodiment, the shielding cover 5 is preferably fixed to the display screen 2 by screws or adhesive.

[0024] In one embodiment of this utility model, the eccentric shaft assembly 4 includes multiple eccentric shafts. The first end of the first eccentric shaft 41 is fixedly connected to the position sensor 31 via a bearing, and the second end of the first eccentric shaft 41 is connected to the back of the display screen 2 via screws. The first end of the second eccentric shaft 42 is fixedly connected to the drive motor 32 via a bearing, and the second end of the second eccentric shaft 42 is connected to the back of the display screen 2 via screws. Preferably, in this embodiment, the design of the eccentric shafts can be flexibly adjusted according to the actual installation situation.

[0025] In one embodiment of this invention, the drive motor 32 controls the second eccentric shaft 42, which drives the display screen 2 to rotate within a range of 90-180°. The first eccentric shaft 41 rotates synchronously with the display screen 2, and the position sensor 31 detects the angle of the first eccentric shaft 41 in real time. Preferably, in this embodiment, when the display screen 2 rotates under external force or driven by the second eccentric shaft 42, the first eccentric shaft 41 rotates synchronously with the display screen 2, driving the input shaft of the position sensor 31 to rotate through the bearing. The position sensor 31 collects the rotation angle signal in real time and transmits the signal to the vehicle's central control system, achieving accurate feedback and control of the display screen 2's angle and avoiding damage to components due to excessive rotation.

[0026] Furthermore, when the vehicle's central control system issues an angle adjustment command, the drive motor 32 starts and drives the second eccentric shaft 42 to rotate through the flexible coupling. The second eccentric shaft 42 uses its own eccentric structure to convert the rotational motion into the flipping or tilting motion of the display screen 2. At the same time, the first eccentric shaft 41 rotates synchronously with the display screen 2 and provides real-time angle feedback through the position sensor 31. When the display screen 2 reaches the target angle, the central control system controls the drive motor 32 to stop running, thereby achieving precise adjustment of the angle of the display screen 2.

[0027] In one embodiment of this invention, an offset distance is formed between the axis of the eccentric rotating shaft assembly 4 and the connection point on the back of the display screen 2. This offset distance is adapted to the thickness of the vehicle's headliner surface. When the display screen 2 is unfolded, the display surface faces downwards and is not obstructed by the vehicle's headliner. Preferably, in this embodiment, the eccentric rotating shaft is designed with an offset axis, and the mounting point of the rotating shaft forms a predetermined offset distance with the back of the display screen 2. This offset distance is adapted to the thickness of the headliner interior layer. When the display screen 2 is unfolded, the offset of the eccentric rotating shaft causes the display screen 2 to sink, increasing the vertical distance between the display surface and the vehicle's headliner, ensuring that the display surface is not visually obstructed.

[0028] In one embodiment of this utility model, when the display screen 2 is closed, the shielding cover 5 maintains a gap of 5±0.5mm with the vehicle headliner; when the display screen 2 is rotated, the shielding cover 5 moves with the display screen 2 to release the gap and ensure that the display screen 2 does not interfere with the vehicle headliner.

[0029] In one embodiment of this utility model, the shielding cover 5 is implemented in one of the following ways: curved surface adaptation type, where the shape of the shielding cover 5 matches the curvature of the vehicle roof; elastic material type, where the shielding cover 5 is made of a compressible material to absorb vibration deformation; glass extension type, where the protective glass of the display screen 2 is extended to serve as the main body of the shielding cover 5.

[0030] In one embodiment of this utility model, the bracket assembly 1 is provided with multiple cavities, and the display screen 2, the modular drive unit 3, the eccentric rotating shaft assembly 4, and the shielding cover 5 are disposed in the cavities. Preferably, in this embodiment, the bracket assembly 1 adopts a three-cavity design: the main cavity houses the closed display screen 2; the drive cavity encapsulates the modular drive unit 3; and the rotating shaft cavity uses a U-shaped groove to house the eccentric rotating shaft assembly 4. Furthermore, the bracket assembly 1 adopts a quick-positioning structure, allowing for pre-installation mounting points to be set on the vehicle roof.

[0031] In one embodiment of this utility model, the control method of the rear ceiling display device includes: pressing the "rear ceiling display device activation button" on the rear armrest side, telling the vehicle intelligent assistant to "turn on the rear ceiling display device" via voice, or triggering the command through the "rear comfort control" menu on the front center console screen.

[0032] In one embodiment of this utility model, the method of using the rear-seat ceiling-mounted display device is as follows: In the initial state, the display screen 2 is fitted into the vehicle roof with the display side facing down, the shielding cover 5 maintains a slight fitting gap with the vehicle roof, the drive unit is in standby mode, and the eccentric shaft assembly 4 is locked and fixed.

[0033] When activated, the rear ceiling-mounted display device allows the vehicle's intelligent assistant to "open the rear ceiling-mounted screen" via voice command. Subsequently, the drive motor 32 drives the second eccentric shaft 42 to rotate, causing the display screen 2 to flip downwards using the eccentric structure. The first eccentric shaft 41 rotates synchronously with the display screen 2, and the position sensor 31 provides real-time feedback on the angle information. When the display screen 2 reaches the default unfolded angle, i.e., when there is no ceiling obstruction and the viewing angle is suitable, the drive motor 32 stops operating, and the eccentric shaft locks.

[0034] If the angle needs to be adjusted, it can be triggered by voice command. The drive motor 32 drives the rotating shaft to rotate in the forward or reverse direction. The position sensor 31 continuously provides feedback on the angle. When the maximum or minimum unfolding angle is reached, the drive motor 32 automatically cuts off power to avoid excessive rotation and damage to the components.

[0035] In the off state, by saying "Close the rear ceiling screen", the drive motor 32 drives the rotating shaft in the opposite direction, and the display screen 2 is retracted towards the ceiling. The cover plate 5 moves with the display screen 2 to release space to prevent interference with the ceiling. After the display screen 2 is completely retracted, the drive motor 32 stops and the cover plate 5 returns to its initial gap.

[0036] This utility model has the following beneficial effects: This invention allows for display without a motor-driven rotation of the screen, satisfying various viewing needs of passengers in camping or double-bed modes. The drive unit is positioned in the rear, ensuring viewing distance while avoiding obstructing the rear sunroof opening, thus maintaining its size and maximizing rear passenger space. Furthermore, the eccentric pivot design enables multi-angle adjustment of the display screen, accommodating zero-gravity seats and seats with large angles. A dynamic cover plate that moves with the display screen also releases gaps, preventing interference with the vehicle roof. In summary, this invention ensures stable operation of multiple functions, enhances the reliability and safety of the device, and optimizes the user experience.
