Description

Technical Field

[0001] This application relates to the field of automotive parts, specifically a flipping mechanism, a display device, and a vehicle. Background Technology

[0002] In the automotive parts industry, in-car ceiling-mounted TVs are a common type of in-car entertainment device, and their electric flip design is the core function for enabling the screen to automatically unfold and close. This design not only affects the user experience but also relates to the stability and aesthetics of the device. Currently, the mainstream electric flip solutions on the market fall into two main categories: the first type places a direct-drive reduction mechanism on one side of the screen to provide power output, while the other side serves as a supporting driven mechanism; the second type places an independent direct-drive system on each side of the screen. While these designs can meet the basic flipping requirements, they still have some shortcomings overall.

[0003] The first type of design in existing technology (i.e., single-sided drive) has three main drawbacks. First, due to the accumulated gear backlash inside the reduction gearbox, the screen is prone to wobbling during rotation, requiring an additional damping mechanism to stabilize it. However, the damping force needs to be much greater than the actual driving force required for rotation, leading to an overkill of the selected motor, resulting in unnecessary energy waste and increased costs. Second, the rotation force is only applied to one side of the screen, and uneven force distribution causes the far end of the screen to sag, preventing complete closure, affecting aesthetics, and causing customer complaints. Finally, this type of solution also requires a locking mechanism to lock the closed state, further increasing manufacturing costs. While the second type of design (i.e., dual-sided drive) solves the problem of uneven force distribution, it requires a drive system on each side, resulting in a relatively high overall cost and limiting its adoption in economy vehicles. In summary, existing technologies still have significant shortcomings in terms of cost control, performance optimization, and user experience. Utility Model Content

[0056] The technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0057] Example 1

[0058] like Figure 1 and Figure 2 As shown, this embodiment provides a flipping mechanism, which has a base 10 and a flipping member 20. The flipping member 20 is movably connected to the base 10 and can be flipped relative to the base 10 to achieve an unfolded state or a closed state relative to the base 10.

[0059] Please see Figure 3In this embodiment, the base 10 is provided with two sliding components 40, two lead screw components 50, and a drive component 60. The two sliding components 40 are arranged in pairs, and each sliding component 40 is connected to a lead screw component 50. Each lead screw component 50 is connected to the drive component 60. The drive component 60 is used to drive the lead screw component 50 to rotate. The rotation of the lead screw component 50 pushes and pulls the sliding component 40, so that the sliding component 40 moves relative to the base 10.

[0060] In this embodiment, as Figure 6 As shown, the base 10 includes a base plate 11 and a housing 12. The sliding assembly 40, the lead screw assembly 50 and the drive assembly 60 are all disposed on the base plate 11. The housing 12 is connected to the base plate 11 and is used to cover the sliding assembly 40, the lead screw assembly 50 and the drive assembly 60.

[0061] Specifically, such as Figure 3 As shown, the sliding components 40 are disposed on both sides of the base plate 11 near the edge. Each sliding component 40 includes a slider 41, which is sleeved on the lead screw assembly 50. The lead screw assembly 50 can push the slider 41 to move along the extension direction of the lead screw assembly 50. The slider 41 is connected to the flipping member 20 through a shaft, thereby providing power for the flipping movement of the flipping member 20.

[0062] In this embodiment, as Figure 3 As shown, the sliding assembly 40 may also include a slider 41 and a slide rail 42. A slide rail 42 is provided below the slider 41 for sliding and supporting the slider 41. The slide rail 42 is fixedly mounted on the base plate 11, and the two slide rails 42 are arranged in parallel. Each slide rail 42 has a slider 41 mounted on it, and the slider 41 is slidably mounted on the slide rail 42, providing stable support for the slider 41.

[0063] like Figure 3 As shown, the lead screw assembly 50 includes a lead screw body 51. Two lead screw bodies 51 are respectively configured to correspond one-to-one with two slide rails 42. Each lead screw body 51 is threadedly engaged with the corresponding slider 41. By rotating itself, the lead screw body 51 can push the slider 41 to move along the slide rail 42.

[0064] In some embodiments, the sliding assembly 40 may also include only a slider 41, which is threadedly connected to the lead screw body 51 and can move along the lead screw body 51. Since the slider 41 can be subjected to forces from both the lead screw body 51 and the flipper 20 simultaneously, even without the support of a support structure such as the slide rail 42, the slider 41 can still move smoothly, providing power for the flipping motion of the flipper 20, thereby reducing structural costs.

[0065] like Figure 3As shown, the drive assembly 60 in this embodiment includes a drive motor 61, which is installed in the middle of the base plate 11. The output end of the drive motor 61 is connected to a reduction gearbox 62, and the output end of the reduction gearbox 62 is connected to a transmission rod 63.

[0066] In this embodiment, the transmission rod 63 passes through the reduction gearbox 62 and extends to opposite sides of the reduction gearbox 62 to drive the lead screw assemblies 50 on both sides. Specifically, as shown... Figure 3 As shown, a first helical gear 52 is provided at the end of the lead screw body 51, and a second helical gear 64 is provided at the end of the transmission rod 63. The transmission rod 63 is set at an angle to the lead screw body 51. The first helical gear 52 and the second helical gear 64 mesh with each other, thereby realizing the transmission connection between the transmission rod 63 and the lead screw body 51.

[0067] Therefore, the drive motor 61 drives the transmission rod 63 to rotate through the reduction gearbox 62. The transmission rod 63 drives the two lead screw bodies 51 to rotate through the helical gears at both ends. The lead screw bodies 51 push the sliders 41, realizing the movement of the two sliders 41. The output shaft of the drive motor 61 can rotate in both forward and reverse directions, thereby causing the two lead screw bodies 51 to rotate in the forward or reverse direction, thus realizing the reciprocating motion of the sliders 41.

[0068] like Figure 3 As shown, in this embodiment, the flipping member 20 is disposed between two pairs of sliding components 40, that is, the flipping member 20 is located between two sliders 41 and is rotatably connected to each slider 41.

[0069] This embodiment also includes a support member 30, one end of which is rotatably connected to the base 10, and the other end is rotatably connected to the flipping member 20, for supporting the flipping member 20. In this embodiment, the slider 41 pushes or pulls the flipping member 20 during movement. The flipping member 20 is supported by the support member 30 during the process of being pushed or pulled by the slider 41, and rotates relative to the support member 30. Therefore, the flipping member 20 can flip relative to the base 10 under the pushing and pulling action of the slider 41 and the supporting action of the support member 30.

[0070] Please see Figure 4 When slider 41 moves to one side, the angle between the flipper 20 and the base 10 increases, at which point the flipper 20 unfolds relative to the base 10. (See also...) Figure 5 When the slider 41 moves to the other side, the angle formed between the flipper 20 and the base 10 becomes smaller. At this time, the flipper 20 closes relative to the base 10, and can even be made parallel to the base 10 or fit against the surface of the base 10 to be completely closed.

[0071] In this embodiment, due to the threaded engagement between the slider 41 and the lead screw body 51, the flipping component 20 can be automatically fixed when it is flipped to any angle relative to the base 10. The threaded engagement between the slider 41 and the lead screw body 51 locks the flipping position of the flipping component 20, effectively preventing the flipping component 20 from loosening, and there is no need to install other locking components.

[0072] The flipping mechanism provided in this embodiment achieves flipping by synchronously pushing and pulling the flipping component 20 with screw assemblies 50 on both sides of the flipping component 20, in conjunction with the rotational support of the support component 30. The screw assemblies 50 driven synchronously on both sides directly push the flipping component 20 to flip, and the flipping component 20 is subjected to uniform force, so that the flipping component 20 can be completely closed and will not sag. The threaded engagement between the slider 41 and the screw body 51 results in strong structural stability, eliminating the need for additional damping or locking components, reducing motor performance requirements and overall manufacturing costs. It solves the problems of wobbling, incomplete closure, and the need for additional locking caused by single-sided drive of the flipping component 20, and avoids the high cost of independent dual-sided drive. This makes the flipping component 20 more stable and less labor-intensive when unfolding and closing, achieving a more reliable, aesthetically pleasing, and economical flipping effect.

[0073] In this embodiment, as Figures 3 to 5 As shown, the flipper 20 is connected to each slider 41 via the first rotating shaft a, the flipper 20 is connected to one end of the support 30 via the second rotating shaft b, and the support 30 is rotatably connected to the base plate 11 via the third rotating shaft c. The first rotating shaft a, the second rotating shaft b, and the third rotating shaft c are arranged in parallel.

[0074] The drive assembly 60 is activated, causing the slider 41 to move. The slider 41 pushes and pulls the flipper 20 via the first rotating shaft a, causing the flipper 20 to rotate relative to the support 30 around the second rotating shaft b. Since the two ends of the support 30 are rotatably connected, the support 30 follows the rotation of the flipper 20 and rotates relative to the base 10 around the third rotating shaft c, thereby realizing the flipping movement of the flipper 20. During the flipping process of the flipper 20, the support 30 moves with the flipper 20 and forms an angle with the flipper 20. The support 30, the base 10 (including the lead screw assembly 50), and the flipper 20 form a triangular connection, which improves the stability of the support for the flipper 20.

[0075] In this embodiment, two support members 30 are provided, respectively located on both sides of the centerline of the flipping member 20. Specifically, the support member 30 is connected to the edge of the flipping member 20 near the lead screw assembly 50, and the second rotating shaft b is located near the center of the flipping member 20, while the first rotating shaft a is located near the edge of the flipping member 20. In this embodiment, the two first rotating shafts a, the two second rotating shafts b, and the two third rotating shafts c are on the same axis to ensure that the flipping member 20 flips smoothly.

[0076] In this embodiment, the first rotating shaft a is connected to the slider 41, and the first rotating shaft a is perpendicular to the extension direction of the slide rail 42. The first rotating shaft a can be fixed on the slider 41 and rotate relative to the flipping member 20, or the first rotating shaft a can be fixed on the flipping member 20 and rotate relative to the slider 41.

[0077] like Figure 6 As shown, the flipping component 20 has bushings 21 on both sides, and the first rotating shaft a extends into the bushing 21 and is rotatably connected to the flipping component 20.

[0078] Preferably, the first rotating shaft a can be a straight rod-shaped structure or a Z-shaped rod structure.

[0079] It is worth mentioning that, in this embodiment, in order to ensure that the movement of the first rotating shaft a can drive the support member 30 to rotate, so that the second rotating shaft b and the third rotating shaft c can rotate, the first rotating shaft a, the second rotating shaft b and the third rotating shaft c should not be on the same plane, and the first rotating shaft a, the second rotating shaft b and the third rotating shaft c should be arranged in a triangle on the projection plane of their axial direction.

[0080] Of course, in some embodiments, the first rotating shaft a, the second rotating shaft b, and the third rotating shaft c can also be arranged on the same plane. In this case, the surface of the base 10 should have an inclined guide sidewall, and one side of the flipping member 20 should have an inclined surface. The inclined surface is in contact with the guide sidewall when the flipping member 20 is closed. Under the pull of the sliding component 40, the inclined surface abuts against the guide sidewall and flips outward of the base 10 through the guide sidewall.

[0081] like Figure 6 and Figure 7 As shown, in one embodiment, the housing 12 has a receiving groove 121 for accommodating the flipper 20, at least a portion of which is located within the receiving groove 121. When the flipper 20 is flipped to the closed position, it can be fully accommodated within the receiving groove 121, thereby reducing the volume of the flipping mechanism.

[0082] In this embodiment, as Figure 7 As shown, the opposite side walls of the receiving groove 121 have a first clearance opening 122 corresponding to the moving direction of the sliding assembly 40. The first rotating shaft a extends from the slider 41 through the first clearance opening 122 to the flipping member 20. The first rotating shaft a moves along the first clearance opening 122 under the pushing and pulling action of the slider 41.

[0083] Furthermore, the inner wall of the receiving groove 121 has a second clearance opening 123 corresponding to the support member 30. The support member 30 extends from the base plate 11 through the second clearance opening 123 into the receiving groove 121 to connect the flipping member 20. In this embodiment, the housing 12 isolates the flipping member 20 from the base plate 11 and the various components disposed on the base plate 11, effectively preventing dust and ensuring the appearance of the flipping mechanism.

[0084] In one embodiment, such as Figure 8 As shown, the support member 30 includes a first support part 31 and a second support part 32. The first support part 31 is connected to the flipping member 20 through a second rotating shaft b. The second support part 32 is connected to the base plate 11 through a third rotating shaft c. The second support part 32 and the first support part 31 are connected at an angle.

[0085] like Figure 9 As shown, a groove 23 is provided on one side surface of the flipping part 20. The second rotating shaft b is rotatably connected to the shaft hole in the groove 23. The first support part 31 can be rotated to be housed in the groove 23 and abut against the inner wall of the groove 23 to support the flipping part 20.

[0086] In other words, when the first support part 31 rotates to the outside of the groove 23, the first support part 31 only supports the flipping part 20 through its end or through the second rotating shaft b; when the first support part 31 rotates to the inside of the groove 23 and abuts against the inner wall of the groove 23, the entire side wall of the first support part 31 is used to support the flipping part 20, which increases the support area and improves the stability of the support for the flipping part 20.

[0087] Example 2

[0088] This embodiment provides a display device having a display screen and a flipping mechanism as mentioned in the above embodiment.

[0089] In one embodiment, the display screen is the flipping component 20 in the flipping mechanism described above. The two ends of the display screen are rotatably connected to the slider 41 via the first rotating shaft a, and the back of the display screen is rotatably connected to the support component 30 via the second rotating shaft b.

[0090] In one embodiment, the display screen is a separate device, and the flipping element 20 in the aforementioned flipping mechanism can be a mounting base 22. For example... Figure 9 As shown, the display screen is mounted on two mounting bases 22, each mounting base 22 having a groove 23, and the first rotating shaft a is rotatably connected within the groove 23. Preferably, the display screen is detachably connected to the two mounting bases 22 to facilitate maintenance and cleaning of the flipping mechanism or the display screen.

[0091] The movement of the flipping mechanism causes the display screen to flip. When in use, the flipping mechanism causes the display screen to unfold and form an angle with the base 10, so that the display screen can be presented at an appropriate angle for passengers to view. When closed, the flipping mechanism causes the display screen to close and be stored in the receiving slot 121 of the base 10, reducing the space occupied and protecting the display screen.

[0092] like Figure 10As shown, the back of the base 10 in this embodiment is provided with a connector 111. The connector 111 is used to fix the base 10 to the top of the carriage, so that the display device is hung upside down in the carriage for passenger use.

[0093] Preferably, a wiring port 112 is provided on the back of the base 10. The wiring port 112 is electrically connected to the display screen and is used to connect to the vehicle's electrical system to ensure the network and circuit connection of the display device.

[0094] The display device in this embodiment has a flipping mechanism, which realizes the unfolding and closing of the display screen. Its operation process is as described above, and will not be repeated here.

[0095] In the entire display device's operating system, the display screen's transmission utilizes a lead screw assembly 50. Because the lead screw assembly 50 is characterized by easy forward drive and labor-intensive reverse drive, when the transmission mechanism (forward drive) reaches the set opening / closing angle and stops working, the slider 41 on the lead screw assembly 50 will stop moving. If a force (reverse drive) is applied to the display screen (flipping component 20) at this time to move the slider 41, a significant overcoming force is required. In the unfolded state, the support component 30, the display screen itself, and the slider 41 together form a stable triangular structure. Therefore, the display screen is not limited by the wobbling problem caused by the accumulated gear clearance tolerances inside the gearbox at any angle. Thus, this system eliminates the need for the final-stage damping mechanism inside the gearbox and the locking mechanism when the display screen is closed, reducing product costs.

[0096] The display utilizes the reverse self-locking characteristic of the lead screw assembly 50, eliminating the need for a locking mechanism when the screen is closed. This design avoids the screen wobble caused by tolerance accumulation in the gearbox, eliminates the need for a damping system, reduces the overall system output force, and thus lowers the performance requirements of the motor. This not only reduces costs but also improves the overall system noise level. The design leverages the stability of a triangle to avoid gear damage issues caused by external forces on the screen end, as seen in similar products on the market when the screen is open. This makes the entire system more stable and adaptable.
