[0029] The following further describes the detailed embodiments of the present application with reference to the drawings.

[0030] It is easy to understand that according to the technical solution of the present application, without changing the essence of the present application, those of ordinary skill in the art can use various structural methods and implementation methods that can be mutually replaced. Therefore, the following detailed embodiments and the drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as all of the present application or as a limitation or restriction on the technical solution of the application.

[0031] The orientation terms such as up, down, left, right, front, back, front side, back side, top, and bottom mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings. They are relative concepts, and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0032] The embodiment of the present application provides an in-vehicle ceiling screen, as Figure 1 and Figure 2 shown. The in-vehicle ceiling screen includes a back plate 10, a support assembly 20, a driving component 30, and a rotating shaft 40. The back plate 10 is fixed to the top of the vehicle compartment. The support assembly 20 is arranged on the back plate 10, and a mounting hole is formed on the support assembly 20. The driving component 30 is arranged on the back plate 10. The driving component 10 and the support assembly 20 are located on both sides of the back plate 10. One end of the rotating shaft 40 passes through the mounting hole, and the other end is connected to the output shaft of the driving component 30. The screen 11 is fixed to the rotating shaft 40, and the screen 11 is located between the driving component 30 and the support assembly 20.

[0033] In the above solution, the driving component 30 may include a motor and a speed reducer. After the motor and the speed reducer are encapsulated as a whole, they are fixed on the backboard 10. The backboard 10 may be a metal backboard, and the metal backboard, as a support structure, connects other structures and components outside the screen 11. The metal backboard can be fixed to the roof crossbeam by bolts and is fixed above the crossbeam of the whole vehicle.

[0034] In the above solution provided by this application, the backboard 10 of the in-vehicle ceiling screen is fixed on the top of the carriage. A support component 20 and a driving component 30 are arranged on the backboard 10. One end of the rotating shaft 40 passes through the mounting hole on the support component 20, and the other end of the rotating shaft 40 is driven by the driving component 30. The screen 11 is fixed on the rotating shaft 40. The driving component 30 and the support component 20 are arranged on both sides of the backboard 10, and the screen 11 is located between the driving component 30 and the support component 20. The controller 50 controls the operating state of the driving component 30 to drive the rotating shaft 40 to drive the screen to flip or reset. In the above solution of this application, the driving component 30 and the support component 20 are arranged on the side of the screen instead of on the screen, reducing the thickness of the ceiling screen.

[0035] In some solutions, the in-vehicle ceiling screen further includes a damping member 60. The damping member 60 is arranged on the backboard 10 and the damping member 60 is in contact with at least one end of the rotating shaft 40. In some solutions, there may be two damping members 60. The two damping members 60 can be respectively arranged at both ends of the rotating shaft 40. The damping member 60 is in contact with both ends of the rotating shaft 40 and can provide a certain damping force during the rotation of the rotating shaft 40 to prevent the rotating speed of the rotating shaft 40 from being too fast under the drive of the driving component 30.

[0036] The magnitude of the damping force provided by the damping member 60 is coordinated with the magnitude of the driving force provided by the driving component 30, enabling the rotating shaft 40 to rotate at an appropriate speed. Specifically, the damping 60 can be realized in various ways. In some embodiments of this application, the damping member 60 is a round rod. The bottom end of the round rod is fixed on the backboard 10, and the side wall of the round rod is in interference fit with at least one end of the rotating shaft 40. If the round rod is in contact with the rotating shaft 40 and is in interference fit, there is a large frictional force between the round rod and the rotating shaft 40 to provide a damping effect.

[0037] In some other solutions, the damping member 60 is an elastic sheet; one end of the elastic sheet is fixed on the backboard 10, and the other end of the elastic sheet abuts against at least one end of the rotating shaft 40. Concave-convex patterns are formed on at least one end of the rotating shaft 40 where the elastic sheet abuts. The elastic sheet has elasticity. When the rotating shaft 40 rotates, the edge of the elastic sheet contacts the concave-convex patterns and undergoes elastic deformation, thereby providing a damping force.

[0038] In some solutions, such asFigure 2 As shown in the figure, the in-vehicle ceiling screen further includes a controller 50, which is located on the other side of the back plate during installation and can be connected to the control end of the driving component 30 through a wire harness. The controller 50 is used to control the operating state of the driving component 30 to drive the rotating shaft 40 to drive the screen 11 to flip or reset; a sensor 80 is arranged on the rotating shaft 40, and the sensor 80 is used to detect the rotation angle of the rotating shaft 40 and send the rotation angle to the controller 50; the controller 50 controls the driving component 30 to stop when the rotation angle reaches a set angle. Specifically, the sensor 80 can be implemented by an encoder. The encoder can be arranged at the end of the rotating shaft 40 on the side opposite to the driving component 30. The encoder is used to detect the rotation angle of the rotating shaft 40, which is the actual flipping angle of the screen 11. After recording and reporting the angle information, the controller 50 can determine whether the screen is reversed in place or reaches the reset state through the rotation angle. For example, when in the reset state, the rotation angle should be zero degrees, and when flipped to the viewing position, the rotation angle should be ninety degrees. The controller 50 can determine whether to control the driving component 30 to continue running by judging the rotation angle.

[0039] Furthermore, the sensor 80 is also used to detect the rotation speed of the rotating shaft 40 and send an alarm prompt signal when the rotation speed exceeds a preset speed range. In the solution of this application, through the action of the reduction gearbox and the damping member 60 in the driving component 30, the rotation speed of the rotating shaft 40 can be prevented from being too fast. Specifically, a speed range is preset in advance. If the rotation speed of the rotating shaft 40 is too fast or too slow, it indicates that there may be a fault in the flipping control process. Therefore, an alarm prompt signal needs to be sent to remind the staff.

[0040] When the screen 11 is closed, if only the support assembly 20 provides the support force, the screen 11 will form a cantilever beam structure, and at this time, the screen 11 may have the risk of sagging. Therefore, the in-vehicle ceiling screen provided in the embodiment of this application further includes a locking member 71 and a locking structure 70. The locking member 71 is arranged on the screen 11; the locking structure 70 is arranged on the back plate 10 and is located on one side of the screen. The locking member 71 matches the locking structure 70 after the screen is reset. In the solution of this application, a locking mechanism 70 is added to the end of the screen 11 and cooperates with the locking member 71 on the screen 11 to limit the position of the screen, ensuring that the screen 11 does not appear uneven in appearance due to the influence of gravity. To avoid the locking mechanism 70 occupying the position of the ceiling and the skylight, the locking mechanism 70 is placed on the side of the screen 11. In some solutions, the locking structure 70 is a clamping groove, and the locking member 71 is a clamping member that cooperates with the clamping groove; or, both the locking structure 70 and the locking member 71 are magnetic members. The locking structure can be simplified through the clamping structure or the magnetic structure.

[0041] In some solutions, the locking member 71 is disposed at a corner of the screen 11, and the corner is located on a side opposite to the rotating shaft 40. That is, the locking member 71 is disposed at the end of the screen 11. When cooperating with the support assembly 20, the support assembly 20 provides a supporting force at the top of the screen, and the locking structure 70 provides a supporting force at the end, so as to better support the screen 11 and overcome the action of the gravity of the screen 11.

[0042] In some solutions, the in-vehicle ceiling screen further includes a shield, which is disposed on the back plate 10 and located between the back plate 10 and the screen. In a specific implementation, the shield can be fixed between the screen 11 and the back plate 10 by means of a buckle, so as to play a role in shielding the non-appearance part of the ceiling screen.

[0043] The embodiment of the present application further provides a vehicle, which includes the in-vehicle ceiling screen according to any one of the above embodiments. The in-vehicle ceiling screen in the solution of the present application realizes the minimization of space in terms of thickness, provides space for other parts of the vehicle ceiling, and improves the utilization efficiency of the space inside the vehicle compartment.

[0044] According to needs, the above technical solutions can be combined to achieve the best technical effect.

[0045] The above are only the principles and preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, based on the principle of the present application, several other modifications can be made, which should also be regarded as the protection scope of the present application.
