[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese patent application No. 202422133187.4, filed on August 30, 2024, entitled "Flip-up Assembly and Vehicle for Ceiling-Mounted Screen", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of vehicle technology, and more particularly to a ceiling-mounted screen flip assembly and a vehicle. Background Technology

[0004] In existing technologies, vehicles have begun to use flip screens in some scenarios, such as flip screens installed on the roof of a car. Users flip the screen open when they need to use it, and flip it closed when they get out of the car or when they do not need to use it.

[0005] However, the weight of in-vehicle rotating screens is significant. During frequent rotations, the existing technology using a single damping method will cause the damping to decay faster, resulting in a decrease in the damping's ability to maintain the screen's stable hovering.

[0006] Utility Model Content

[0007] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a ceiling-mounted screen flip assembly. The ceiling-mounted screen flip assembly, through a dual-damping installation method with a first damping structure in the active mechanism and a second damping structure in the driven mechanism, can effectively reduce damping attenuation and ensure smooth operation and stable hovering of the ceiling-mounted screen.

[0008] The ceiling-mounted screen flip assembly according to an embodiment of this application includes: an active mechanism, which includes a driving member, a first mounting shell, and a first output member. The first output member is rotatably mounted on the first mounting shell. The driving member is poweredly connected to the first output member and is used to drive the first output member to rotate. A first damping structure is provided between the driving member and the first output member. A driven mechanism includes a second mounting shell and a second output member. The second output member is rotatably mounted on the second mounting shell. A second damping structure is provided between the second mounting shell and the second output member. The first output member and the second output member are respectively used to connect to the ceiling-mounted screen.

[0009] According to the ceiling-mounted screen flip assembly of this application embodiment, the driving member of the active mechanism drives the first output member to rotate, thereby driving the ceiling-mounted screen and the driven mechanism to flip. The active mechanism is provided with a first damping structure, and the driven mechanism is provided with a second damping structure. When the driving member drives the first output member to rotate, the first damping structure between the driving member and the first output member generates frictional damping between the rotation of the driving member and the rotation of the first output member, which makes the first output member act more smoothly on the ceiling-mounted screen of the vehicle. Similarly, the second damping structure provided between the second output member and the second mounting shell generates frictional damping between the second output member and the second output member, which can further ensure that the ceiling-mounted screen moves more smoothly. Through the first damping structure and the second damping structure, the ceiling-mounted screen has appropriate damping on both the active and driven sides during the flipping process. This damping can ensure the smooth operation and stable hovering of the ceiling-mounted screen.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] The following description, with reference to Figures 1-12, describes the ceiling-mounted screen flipping assembly 100 according to an embodiment of this application. The first output component 13 is rotated by the drive component 11 of the active mechanism 1, thereby causing the ceiling-mounted screen 5 and the driven mechanism 2 to flip. The active mechanism 1 is provided with a first damping structure 14, and the driven mechanism 2 is provided with a second damping structure. The first damping structure 14 and the second damping structure enable the ceiling-mounted screen 5 to have appropriate damping during the flipping process. This damping can ensure the smooth operation and stable hovering of the ceiling-mounted screen 5.

[0044] As shown in Figures 1-12, a ceiling-mounted screen flipping assembly 100 according to an embodiment of this application includes: an active mechanism 1 and a driven mechanism 2.

[0045] The active mechanism 1 includes a drive member 11, a first mounting shell 12, and a first output member 13. The first output member 13 is rotatably mounted on the first mounting shell 12. The drive member 11 is poweredly connected to the first output member 13 and is used to drive the first output member 13 to rotate. A first damping structure 14 is provided between the drive member 11 and the first output member 13. The driven mechanism 2 includes a second mounting shell 22 and a second output member 21. The second output member 21 is rotatably mounted on the second mounting shell 22. A second damping structure is provided between the second mounting shell 22 and the second output member 21. The first output member 13 and the second output member 21 are respectively used to connect to the ceiling screen 5.

[0046] First, the ceiling-mounted screen 5 of vehicle 200 is a special screen design focused on creating a third space within the vehicle, enabling in-vehicle leisure and entertainment activities. When not in use, this screen is hidden in the roof, saving interior space and maintaining an aesthetically pleasing appearance. When needed, the screen lowers, creating a private in-vehicle cinema and providing passengers with a comfortable viewing experience. Referring to Figure 12, vehicle 200 includes a first-row seating area 201 and a rear seating area 202. The ceiling-mounted screen's flip assembly 100 is located on the top of vehicle 200, generally positioned behind the first-row seating area 201 and in front of the rear seating area 202, primarily for the convenience of passengers in the rear seating area 202.

[0047] In practice, the first output component 13 of the active mechanism 1 is mounted on the first mounting housing 12, and the second output component 21 of the driven mechanism 2 is mounted on the second mounting housing 22. The first output component 13 is supported and protected by the first mounting housing 12, and the second output component 21 is supported and protected by the second mounting housing 22. The driving component 11 of the active mechanism 1 is electrically connected to the first output component 13. If the driving component 11 and the first output component 13 can be indirectly or directly connected, then the driving component 11, as a power source, can drive the first output component 13. When the first output component 13 rotates, it connects to the ceiling screen 5. In other words, the rotation of the first output component 13 can drive the ceiling screen 5 to rotate. In addition, the second output component 21 of the driven mechanism 2 is also connected to the ceiling screen 5. The combined action of the first output component 13 and the second output component 21 can make the ceiling screen 5 rotate to the unfolded state or to the retracted state, so that passengers can unfold the ceiling screen 5 when using it and retract it when not using it, thereby saving space and maintaining the flatness of the vehicle interior.

[0048] In addition, a first damping structure 14 is provided between the driving component 11 and the first output component 13. When the driving component 11 outputs power to the first output component 13 through the output shaft 111, the first damping structure 14 causes frictional resistance between the driving component 11 and the first output component 13. This frictional resistance does not affect the first output component 13 from driving the ceiling screen 5, while ensuring that the ceiling screen 5 can move smoothly during rotation and achieve stable hovering.

[0049] Similarly, the ceiling screen 5 is also connected to the driven mechanism 2. During the rotation of the ceiling screen 5, it will also drive the second output component 21 of the driven mechanism 2 to rotate. The second output component 21 is installed in the second mounting shell 22, and a second damping structure is provided between the second output component 21 and the second mounting shell 22. The second damping structure can make the second output component 21 have friction, but at the same time, this friction does not affect the normal rotation of the ceiling screen 5. That is, by combining the first damping structure 14 and the second damping structure, compared with using a single damping structure, the smooth movement and smooth hovering of the ceiling screen 5 can be further achieved.

[0050] Therefore, the ceiling screen flip assembly 100 of this application embodiment, the first damping structure 14 and the second damping structure can reduce the attenuation of damping during frequent flipping, so that the ceiling screen 5 can maintain good stability after flipping for a long time; moreover, when the vehicle 200 passes through a bumpy road section, the ceiling screen 5 can still absorb these impact vibrations through damping force to achieve stable hovering.

[0051] In some embodiments, the first damping structure 14 includes a mounting shaft 141, a mounting plate 142, a damping element 143, and a fastening nut 114. The driving member 11 is poweredly connected to the mounting shaft 141 to drive the mounting shaft 141 to rotate. The mounting shaft 141 is connected to the first output member 13 to drive the first output member 13 to rotate. The mounting plate 142 and the damping element 143 are both sleeved on the outside of the mounting shaft 141. The mounting plate 142 is fixedly connected to the first mounting shell 12. The mounting shaft 141 is connected to the fastening nut 144, which is used to press the damping element 143 toward the mounting plate 142.

[0052] The drive component 11 can be directly or indirectly connected to the mounting shaft 141. The first output component 13 is fixedly connected to the ceiling screen 5, and the mounting shaft 141 is also fixedly connected to the first output component 13. Therefore, when the mounting shaft 141 rotates, it can drive the first output component 13 to rotate, thereby driving the ceiling screen 5 to rotate. At the same time, during the rotation of the mounting shaft 141, there is friction between the damping component 143 on the mounting shaft 141 and the mounting shaft 141. This friction forms damping between the mounting shaft 141 and the damping component 143, making the process of the mounting shaft 141 driving the first output component 13 to rotate more smoothly, that is, driving the ceiling screen 5 to rotate more smoothly.

[0053] Specifically, referring to Figures 4-7, a mounting support plate 142 is sleeved on the mounting shaft 141. The mounting support plate 142 is fixedly connected to the first mounting shell 12. Simultaneously, the mounting shaft 141 rotates relative to the mounting support plate 142, and the damping element 143 is sleeved on the mounting shaft 141. Then, a fastening nut 144 is sleeved on the mounting shaft 141 and threadedly connected to it to press the damping element 143 tightly. After the fastening nut 144 is sleeved on the mounting shaft 141, it can limit the movement of the damping element 143, preventing it from being stopped. 43 generates a large axial displacement; the damping element 143 may include multiple friction pads 1431. As shown in FIG7, the multiple friction pads 1431 are sequentially sleeved on the mounting shaft 141. Friction is generated between the multiple friction pads 1431 and between the multiple friction pads 1431 and the mounting shaft 141. Frictional resistance is generated between the mounting support plate 142 and the mounting shaft 141, thereby forming damping. Under the action of frictional resistance, the driving element 11 drives the first output element 13 to rotate, thereby driving the ceiling screen 5 to rotate smoothly.

[0054] In some embodiments, the mounting shaft 141 includes a first shaft segment 1411, a second shaft segment 1412, a third shaft segment 1413, and a fourth shaft segment 1414 distributed sequentially along the axial direction. The fastening nut 144, the mounting support plate 142, and the damping member 143 are all sleeved on the first shaft segment 1411, and the mounting support plate 142 and the damping member 143 are pressed between the fastening nut 144 and the second shaft segment 1412. The third shaft segment 1413 is used for power connection with the driving member 11, and the fourth shaft segment 1414 is connected to the first output member 13.

[0055] In practice, a damping element 143 is set through the first shaft segment 1411, and the third shaft segment 1413 is poweredly connected to the drive element 11. The fourth shaft segment 1414 is connected to the first output element 13. Different positions of the mounting shaft 141 can be connected to the damping element 143, the drive element 11, and the first output element 13 simultaneously. Furthermore, the first shaft segment 1411, the second shaft segment 1412, and the third shaft segment 1413 of the mounting shaft 141 can be designed with different structures to meet the connection requirements of the mounting shaft 141 with the damping element 143, the drive element 11, and the first output element 13, respectively. For example, the damping element 143 is rotatably connected to the first shaft segment 1411, and the fourth shaft segment 1414 is interference-fitted to the first output element 13.

[0056] Referring to Figures 6 and 7, the first shaft segment 1411 is used to sleeve the mounting plate 142, the damping element 143, and the fastening nut 144. The diameter of the first shaft segment 1411 is smaller than the diameter of the second shaft segment 1412, so as to form a stepped limiting surface between the first shaft segment 1411 and the second shaft segment 1412. The mounting plate 142 is sleeved and connected to the first shaft segment 1411. The first shaft segment 1411 is also sleeved with a plurality of friction pads 1431. One friction pad 1431 is located on one side of the mounting plate 142 and between the mounting plate 142 and the stepped limiting surface. The other plurality of friction pads 1431 are located on the other side of the mounting plate 142 and between the fastening nut 144 and the mounting plate 142. The friction between the friction pad 1431 and the mounting plate 142 is equivalent to the mutual friction between one friction pad 1431 and another. By setting the friction pad 1431 on one side of the mounting plate 142, the mounting plate 142 can be positioned on the mounting shaft 141 and easily connected to the first mounting shell 12, thus supporting the mounting shaft 141. At the same time, it ensures that frictional force is generated between the multiple friction pads 1431 and between the friction pads 1431 and the mounting plate 142. Combined with the damping between the friction pads 1431 and the mounting shaft 141, this forms damping that allows the mounting shaft 141 to drive the first output component 13 and the ceiling screen 5 to rotate stably. Moreover, the first shaft segment 1411 is a stepped shaft, which facilitates the connection and fastening of the nut 144 and the pressure friction pads 1431.

[0057] In addition, the drive member 11 transmits power between the third shaft segment 1413 and the mounting shaft 141, and the mounting shaft 141, under the action of the drive member 11, transmits power between the fourth shaft segment 1414 and the first output member 13. The diameter of the third shaft segment 1413 is smaller than the diameter of the second shaft segment 1412, and the diameter of the fourth shaft segment 1414 is smaller than the diameter of the third shaft segment 1413, which better distinguishes the first shaft segment 1411, the second shaft segment 1412, the third shaft segment 1413 and the fourth shaft segment 1414. At the same time, it can also limit the structure of the mounting shaft 141 in different positions.

[0058] In some embodiments, the active mechanism 1 further includes a transmission gear set 15 and an output gear 16. The transmission gear set 15 includes a plurality of intermediate transmission members, which mesh sequentially. The output shaft 111 of the drive member 11 is connected to the first intermediate transmission member and the last intermediate transmission member meshes with the output gear 16. The output gear 16 is sleeved on the mounting shaft 141 and drives the mounting shaft 141 to rotate when it rotates.

[0059] In practice, the transmission gear set 15 can transmit power not only between parallel shafts, but also between non-parallel, coplanar, and intersecting shafts. It can also achieve smooth and precise transmission. In addition, by combining gears of different sizes, the rotational speed can be increased or decreased and the torque can be changed, so that the rotational speed and torque are within a suitable range.

[0060] Specifically, referring to Figure 5, the transmission gear set 15 includes a first gear 151, a second gear 152, a third gear 153, a fourth gear 154, and a fifth gear 155. That is to say, at this time, the first gear 151, the second gear 152, the third gear 153, the fourth gear 154, and the fifth gear 155 are all intermediate transmission components, with the first gear 151 being the first intermediate transmission component and the fifth gear 155 being the last intermediate transmission component.

[0061] The fifth gear 155 meshes with the output gear 16. The first gear 151 is sleeved on and fixedly connected to the output shaft 111 of the drive member 11. The second gear 152 meshes with the first gear 151, and the central axis of the second gear 152 is perpendicular to the central axis of the first gear 151. The third gear 153 meshes with the second gear 152, and the central axis of the third gear 153 is perpendicular to the central axis of the second gear 152. The fourth gear 154 meshes with the third gear 153, and the central axis of the fourth gear 154 is parallel to the central axis of the third gear 153. The fifth gear 155 meshes with the fourth gear 154, and the central axis of the fifth gear 155 is parallel to the central axis of the fourth gear 154. Meanwhile, a positioning ring 145 is fitted on the third shaft segment 1413 of the mounting shaft 141, and the output gear 16 is fitted on the positioning ring 145 of the third shaft segment 1413 and is relatively fixedly connected to the mounting shaft 141. At this time, when the output shaft 111 of the drive member 11 transmits power to the first gear 151, the power is transmitted in sequence to the second gear 152, the third gear 153, the fourth gear 154, the fifth gear 155 and the output gear 16 through the first gear 151. The output gear 16 drives the mounting shaft 141 to rotate, and the rotation of the mounting shaft 141 will drive the first output member 13 to rotate. The first output member 13 is poweredly connected to the ceiling screen 5, thereby realizing that the mounting shaft 141 drives the ceiling screen 5 to rotate.

[0062] At this time, by setting the transmission gear set 15 and the output gear 16, the output shaft 111 of the drive component 11 and the mounting shaft 141 can be arranged in parallel, making the active mechanism 1 of the entire ceiling screen 5 more concentrated.

[0063] In addition, a first bearing 1211 and a second bearing 1221 are respectively provided at one end of the first mounting housing 12 near the mounting shaft 141 and at the other end near the first output component 13. The first bearing 1211 and the second bearing 1221 enable the mounting shaft 141 to rotate relative to the first mounting housing 12 and are used to provide rotational support for the mounting shaft 141.

[0064] In some embodiments, the first mounting housing 12 includes a first housing portion 121 and a second housing portion 122. The first housing portion 121 and the second housing portion 122 are engaged and define a first mounting cavity. The mounting shaft 141 passes through the first housing portion 121 and the second housing portion 122. The transmission gear set 15 and the output gear 16 are both located in the first mounting cavity.

[0065] First, by setting the mounting housing as a first housing portion 121 and a second housing portion 122, and the first mounting cavity formed by the first housing portion 121 and the second housing portion 122 can be used to set the transmission gear set 15, the first housing portion 121 and the second housing portion 122 are detachable, which facilitates the installation and maintenance of the transmission gear set 15; at the same time, the first housing portion 121 and the second housing portion 122 are connected to form the whole of the first mounting housing 12, which can protect the transmission gear set 15, prevent dust, debris and other objects from falling into the position of the transmission gear set 15, and ensure the smooth transmission of torque of the drive component 11; in addition, setting the transmission gear set 15 in the first mounting housing 12 can also prevent the transmission gear set 15 from affecting the occupants of the vehicle, and the transmission gear set 15 set in the first mounting housing 12 can improve the aesthetics of the ceiling screen flip assembly 100.

[0066] In some embodiments, the first output member 13 includes a first connecting shaft portion 131, the first connecting shaft portion 131 having an axially open connecting hole 1311, and a fourth shaft segment 1414 being axially inserted into the connecting hole 1311 and engaging with the first output member 13 in a circumferential transmission cooperation.

[0067] In practice, the fourth shaft segment 1414 is inserted into the connecting hole 1311 of the first connecting shaft portion 131 and is interference-fitted with the first connecting shaft portion 131. Thus, when the mounting shaft 141 is driven, it drives the first connecting shaft portion 131 to rotate. The first connecting shaft portion 131 is powered to the ceiling screen 5. By inserting the fourth shaft segment 1414 of the mounting shaft 141 into the connecting hole 1311 and powering it with the first output component 13, the connection and disassembly are convenient. When it is necessary to replace the first output component 13 or the mounting shaft 141, it is easy to replace.

[0068] The fourth shaft segment 1414 is a prism structure with trapezoidal sides. The fourth shaft segment 1414 and the connecting hole 1311 of the first connecting shaft 131 are interference fit. Therefore, the mounting shaft 141 will always be subjected to the damping force provided by the first damping structure 14 during rotation. When the driving component 11 stops working, the ceiling screen 5 can be stably suspended in any angle range, thereby meeting the viewing angle requirements of different users for the ceiling screen 5.

[0069] In some embodiments, the second output member 21 includes a second connecting shaft portion 211, and the second damping structure includes an elastic damping member 27. The elastic damping member 27 is installed inside the second mounting housing 22 and is circumferentially limited to the second mounting housing 22. The second connecting shaft portion 211 extends into the second mounting housing 22, and the elastic damping member 27 is sleeved outside the second connecting shaft portion 211 and is interference-fitted with the second connecting shaft portion 211.

[0070] In practice, the second connecting shaft 211 is poweredly connected to the ceiling screen 5. The ceiling screen 5 rotates under the drive of the active mechanism 1. When the ceiling screen 5 rotates, it drives the second connecting shaft 211 to rotate. The second connecting shaft 211 is interference-fitted with an elastic damping element 27. The elastic damping element 27 is made of a highly wear-resistant elastic material. Interference fits generally include tight fits and loose fits. Two structural parts that are tight fit cannot rotate relative to each other, while two structural parts that are loose fit can rotate relative to each other. The interference fit here allows the second connecting shaft 211 to rotate relative to the elastic damping element 27 while generating friction. This friction forms damping between the second connecting shaft 211 and the elastic damping element 27, thereby enabling the ceiling screen 5 to rotate more stably.

[0071] Furthermore, the second connecting shaft 211 extends into the second mounting housing 22, and the elastic damping member 27 fitted onto the second connecting shaft 211 is fixedly connected to the second mounting housing 22. That is, after the elastic damping member 27 is installed, it remains stationary while the second connecting shaft 211 rotates relative to it. The second connecting shaft 211 is then poweredly connected to the ceiling screen 5; the frictional damping force between the elastic damping member 27 and the second connecting shaft 211 ensures smooth rotation of the ceiling screen 5. Moreover, the second connecting shaft 211 is fitted with a bushing 25 and a bearing 26, which support the second connecting shaft 211 when it extends into the second mounting housing 22, improving the stability of its rotation.

[0072] In some embodiments, one of the outer peripheral wall of the elastic damping member 27 and the inner peripheral wall of the second mounting shell 22 is provided with a limiting groove 221 and the other is provided with a limiting protrusion 271. The limiting protrusion 271 extends along the axial direction of the elastic damping member 27 and is inserted into the limiting groove 221 and is circumferentially limited.

[0073] In practice, the elastic damping element 27 may have a limiting protrusion 271 on its outer periphery, while the inner wall of the second mounting shell 22 may have a limiting groove 221. The elastic damping element 27 can be detachably installed inside the second mounting shell 22, and the limiting protrusion 271 is engaged with the limiting groove 221. This makes the installation and removal of the elastic damping element 27 more convenient. If the elastic damping element 27 is damaged, it can be easily replaced, and the relative fixation between the elastic damping element 27 and the second mounting shell 22 can be ensured. Alternatively, the limiting protrusion 271 can be provided on the inner wall of the second mounting shell 22, and the limiting groove 221 can be provided on the outer periphery of the elastic damping element 27. This also allows for a detachable connection between the elastic damping element 27 and the second mounting shell 22, while ensuring that the elastic damping element 27 and the second mounting shell 22 remain relatively fixed.

[0074] The outer peripheral wall of the elastic damping member 27 is provided with limiting protrusions 271 distributed at equal intervals along the circumference, while the inner wall of the second mounting shell 22 is provided with a plurality of corresponding limiting grooves 221. The cooperation of the plurality of limiting protrusions 271 and the plurality of limiting grooves 221 can improve the reliability of the elastic damping member 27 installed in the second mounting shell 22. At the same time, it can make the elastic damping member 27 bear force evenly, so the friction force of the second connecting shaft 211 relative to the elastic damping member 27 is more uniform, thereby improving the stability of the rotation of the ceiling screen 5.

[0075] In some embodiments, the inner peripheral wall of the elastic damping member 27 is provided with a lubrication groove 272, which is open toward the outer peripheral wall of the second connecting shaft portion 211, and is filled with lubricating oil.

[0076] In practice, the elastic damping element 27 is configured to have an interference fit with the second connecting shaft 211. A lubrication groove 272 is provided on the inner peripheral wall of the elastic damping element 27. The lubrication groove 272 can be filled with lubricating oil. That is, while ensuring the interference fit, the second connecting shaft 211 can rotate relative to the elastic damping element 27 under the action of lubricating oil, thereby generating damping force, improving the service life of the elastic damping element 27, and reducing the problem of poor torque linearity caused by the deformation of the elastic damping element 27.

[0077] The lubrication grooves 272 are provided in multiples and distributed at intervals along the inner circumference of the elastic damping member 27. Each lubrication groove 272 extends along the axial direction of the elastic damping member 27. For example, in the embodiment of this application, there are eight lubrication grooves 272. This ensures that the entire elastic damping member 27 and the second connecting shaft portion 211 are in an interference fit, while also enabling lubrication between the elastic damping member 27 and the second connecting shaft portion 211. This allows the second connecting shaft portion 211 to rotate relative to the elastic damping member 27, thereby reducing the wear of the elastic damping member 27.

[0078] In some embodiments, the ceiling-mounted screen flip assembly 100 further includes a detection structure 24 and a control module 3. The detection structure 24 is used to detect the angle state of the second output member 21. The control module 3 controls the drive member 11 to stop outputting power when the second output member 21 reaches the closing angle of the ceiling-mounted screen 5 or when the ceiling-mounted screen 5 is unfolded to the maximum angle.

[0079] In practice, the control module 3 can not only control the drive component 11 of the active mechanism 1, but also output torque through the output shaft 111 of the drive component 11 to flip or stop the flipping of the ceiling screen 5. The maximum angle of the ceiling screen 5 can be pre-designed, that is, the range of rotation of the ceiling screen 5 driven by the drive component 11 is from closed to unfolded to the maximum angle. The control module 3 can also control the detection structure 24 to detect the angle rotation signal output by the second connecting shaft 211 of the driven mechanism 2. When the detection structure 24 detects that the ceiling screen 5 is at the closed angle, the control module 3 controls the drive component 11 to stop, or when the detection structure 24 detects that the ceiling screen 5 is at the maximum angle, the control module 3 controls the drive component 11 to stop. This makes it convenient to control the rotation and stop of the ceiling screen 5. The drive component 11 can work according to the actual situation to make the ceiling screen 5 rotate within a suitable angle range.

[0080] The ceiling-mounted screen's flip assembly 100 also includes a detection auxiliary structure 28, which includes an angle detection gear set 281 and a gear bracket 282. The angle detection gear set 281 includes a first detection gear 2811 and a second detection gear 2812. The first detection gear 2811 is connected to the end of the second connecting shaft 211, and the second detection gear 2812 is located on one side of the first detection gear 2811 and meshes with it. The second detection gear 2812 is equipped with a magnet 2813. When the second detection gear 2812 rotates, the magnetic poles also rotate, and the magnetic field changes accordingly. When the magnetic poles pass through the detection structure 24, which is an angle sensor, the magnetic flux changes, thereby generating an induced electromotive force in the angle sensor. The angle sensor converts the electrical signal into a rotation signal, thereby measuring the rotation angle of the second detection gear 2812. Magnet 2813 is opposite to detection structure 24, gear bracket 282 is connected to second mounting shell 22, the rotation angle of second connecting shaft 211 is obtained by the angle of first detection gear 2811, and the rotation angle is transmitted to control module 3 so that control module 3 can understand the rotation angle of ceiling screen 5.

[0081] In addition, the second mounting shell 22 is also connected to the top cover 23, which has an opening. The detection structure 24 is connected to the opening of the top cover 23. The top cover 23 has a wire sleeve 231 on the outside of the position opposite to the first detection gear 2811. The top cover 23 can protect the ends of the first detection gear 2811 and the second detection gear 2812. Moreover, the wire sleeve 231 makes it easy to observe the rotation dynamics of the first detection gear 2811. The wire sleeve 231 also facilitates the connection between the detection structure 24 and the control module 3 through the transmission line to form information transmission, facilitates the passage of the transmission line, prevents wear on the transmission line, and protects the transmission line.

[0082] In some embodiments, the ceiling-mounted screen flip assembly 100 further includes: a mounting bracket 6, which is adapted to be connected to a vehicle body, a first mounting shell 12 and a second mounting shell 22 respectively connected to the mounting bracket 6, and the ceiling-mounted screen 5 adapted to be folded to the mounting bracket 6 or opened relative to the mounting bracket 6.

[0083] First, the active mechanism 1, the driven mechanism 2, and the control module 3 are all fixed to the mounting bracket 6 with bolts. The mounting bracket 6 then mates with the mounting surface on the vehicle roof to complete the placement of the vehicle-mounted ceiling screen 5 on the car. Connecting the ceiling screen 5 to the mounting bracket 6, and connecting the mounting bracket 6 to the vehicle body, facilitates the connection between the ceiling screen 5 and the vehicle body while ensuring the normal rotation of the ceiling screen 5. The mounting bracket 6 supports the ceiling screen 5 and also facilitates the installation of the first mounting shell 12 and the second mounting shell 22, which in turn facilitates the installation of the active mechanism 1 and the driven mechanism 2, allowing them to be supported and connected to the ceiling screen 5. Furthermore, by setting up the mounting bracket 6, the integration of the ceiling screen 5 with the active mechanism 1 and the driven mechanism 2 is improved.

[0084] In addition, the mounting bracket 6 is integrated with the vehicle body. When the ceiling screen 5 is opened relative to the mounting bracket 6, it is also open relative to the vehicle body. When the ceiling screen 5 is folded relative to the vehicle body, it is also folded relative to the vehicle body. The folded ceiling screen 5 can reduce the space occupied by the ceiling screen 5 in the vehicle body.

[0085] In some embodiments, one of the mounting bracket 6 and the ceiling screen 5 is provided with a locking member 4 and the other is provided with a locking hole 51. The locking member 4 is adapted to lock into the locking hole 51 after the ceiling screen 5 is folded to the mounting bracket 6, and the locking member 4 retracts from the locking hole 51 when the ceiling screen 5 needs to be unfolded.

[0086] Specifically, when the control module 3 receives the angle signal of the second output component 21 detected by the detection structure 24, and the angle of the second output component 21 is the rotation angle corresponding to the folding of the ceiling screen 5, the control module 3 controls the drive component 11 of the active mechanism 1 to stop. At this time, the control locking component 4 cooperates with the locking hole 51 to lock the ceiling screen 5, preventing the ceiling screen 5 from loosening during the driving of the vehicle 200, especially when the vehicle 200 shakes violently up and down on uneven road sections, ensuring that the ceiling screen 5 will not flip out. Similarly, when the ceiling screen 5 needs to be used, the control module 3 controls the locking component 4 to retract from the locking hole 51 to realize the normal rotation of the ceiling screen 5, so that the ceiling screen 5 is rotated to an angle that is convenient for passengers to view.

[0087] Referring to Figures 1-3, the locking component 4 may include a locking part 41. If the locking component 4 is a drive motor, the locking part 41 is the motor drive shaft. A locking groove is provided on the side of the ceiling screen 5, which is equivalent to the locking hole 51 mentioned above. When the control module 3 determines that the ceiling screen 5 is folded into place, it controls the drive motor to work, so that the motor drive shaft of the drive motor extends into the locking groove, thereby achieving the locking of the locking part 41 and the locking groove. In addition, an elastic material can be provided at the locking groove on the side of the ceiling screen 5. When the locking part 41 extends into the locking groove, it can compress the elastic material of the locking groove, thereby preventing the pressure of the locking part 41 from affecting the ceiling screen 5.

[0088] Furthermore, the mounting bracket 6 is equipped with two locking elements 4, which are located on both sides of the ceiling screen 5. At the same time, both sides of the ceiling screen 5 are equipped with locking grooves. The two locking elements 4 cooperate with the corresponding locking grooves to lock. Moreover, the two locking elements 4 are located at the ends of the mounting bracket 6 away from the active mechanism 1 and the driven mechanism 2. In this way, when the ceiling screen 5 is folded, the setting of the two locking elements 4 can make the two sides of the ceiling screen 5 evenly stressed and lock the ceiling screen 5 more reliably.

[0089] In some embodiments, the mounting bracket 6 forms a storage area 7, the active mechanism 1 and the driven mechanism 2 are respectively located on both sides of the storage area 7, the ceiling screen 5 is adapted to be stored in the storage area 7, and the first output member 13 and the second output member 21 are respectively connected to the two ends of the ceiling screen 5.

[0090] In practice, the first output component 13 and the second output component 21 are connected to both ends of the ceiling screen 5. When the first output component 13 transmits power to the ceiling screen 5, the ceiling screen 5 can directly transmit power to the second output component 21, resulting in smoother power transmission. Moreover, the active mechanism 1 and the driven mechanism 2 are both located at both ends of the ceiling screen 5 and in the storage area 7 of the mounting bracket 6, which increases the integration of the active mechanism 1 and the driven mechanism 2 with the ceiling screen 5. Furthermore, when the ceiling screen 5 is folded, it is located within the storage area 7, which improves the flatness of the ceiling screen 5 with the vehicle body.

[0091] Furthermore, it should be noted that the detection structure 24 simultaneously detects the rotation angle of the ceiling screen 5 when it is rotated to the storage position. At the same time that the ceiling screen 5 enters the storage position, the control module 3 controls the locking component 4 to lock the ceiling screen 5, so that the locking operation of the locking component 4 and the time when the ceiling screen 5 rotates to the storage position can be well kept in sync. There will be no situation where the locking operation of the locking component 4 is performed before the ceiling screen 5 rotates to the storage position. The coordination between the locking component 4 and the ceiling screen 5 rotating to the storage position is good.

[0092] In some embodiments, the first output member 13 has a first mounting surface 132, which is adapted to be attached to and connected with the ceiling screen 5; and the second output member 21 has a second mounting surface 212, which is adapted to be attached to and connected with the ceiling screen 5.

[0093] Of course, the first output component 13 may have a first mounting surface 132, which is adapted to be attached to the ceiling screen 5, or the second output component 21 may have a second mounting surface 212, which is adapted to be attached to the ceiling screen 5. This can also satisfy the requirement that the first output component 13 transmits power to the second output component 21 through the ceiling screen 5.

[0094] In practice, the first mounting surface 132 of the first output component 13 is connected to the side of the ceiling screen 5 near the mounting bracket 6. Similarly, the second mounting surface 212 of the second output component 21 is connected to the side of the ceiling screen 5 near the mounting bracket 6. Both the first mounting surface 132 and the second mounting surface 212 are connected to the end of the ceiling screen 5 by screws, that is, avoiding the position of the screen. By setting the first mounting surface 132 and the second mounting surface 212, the connection area between the first output component 13 and the ceiling screen 5 is increased, and the connection area between the second output component 21 and the ceiling screen 5 is also increased, thereby improving the stability of the drive component 11 driving the ceiling screen 5 to rotate.

[0095] It should be noted that, in the embodiment of this application, the rotating assembly 100 of the ceiling screen can reduce the damping attenuation by setting the first damping structure 14 and the second damping structure, while also facilitating the setting and control of the anti-pinch force of the ceiling screen 5.

[0096] Alternatively, the ceiling-mounted screen flip assembly 100 of this application embodiment can also have two damping structures installed in the active mechanism 1 and one damping structure installed in the driven mechanism 2, adopting a three-damping installation method to further distribute the damping force, reduce the damping attenuation, and ensure the smooth operation and stable suspension of the ceiling-mounted screen 5; or the oil groove, grease, material hardness, etc. of the damping structure can also be changed to improve the attenuation rate of the damping structure.

[0097] This application also discloses a vehicle 200, including a ceiling-mounted screen 5, which is disposed on the top of the vehicle interior. It also includes the aforementioned ceiling-mounted screen flipping assembly 100. The first output component 13 is driven to rotate by the drive component 11 of the active mechanism 1, thereby causing the ceiling-mounted screen 5 and the driven mechanism 2 to flip, so that the ceiling-mounted screen 5 flips from a folded state on the roof to an unfolded state. The active mechanism 1 is provided with a first damping structure 14, and the driven mechanism 2 is provided with a second damping structure. The first damping structure 14 and the second damping structure enable the ceiling-mounted screen 5 to have appropriate damping during the flipping process. This damping can ensure that the ceiling-mounted screen 5 operates smoothly and hovers stably, improving the user experience when the ceiling-mounted screen 5 of the vehicle 200 is hovering. At the same time, it prevents the ceiling-mounted screen 5 from shaking and flipping out when it is stored.
