[0071] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts are within the scope of protection of the present application.

[0072] In the present application, the term "vertical" refers to a direction substantially perpendicular to the vehicle roof panel; the term "horizontal" refers to a direction substantially parallel to the vehicle roof panel.

[0073] Figure 1 Schematically shows a vehicle 1 according to an embodiment of the present application. As Figure 1 shown, a display device 2 for the vehicle roof panel 11 (hereinafter, simply referred to as the display device 2) is installed on the vehicle roof panel 11 of the passenger compartment of the vehicle 1. For example, the display device 2 is located between the front row seats 12 and the rear row seats 13 to provide entertainment for the rear row occupants.

[0074] Next, the display device 2 will be described.

[0075] As Figure 2 and Figure 4 shown, the display device 2 includes a display component 3, a driving component 4, and a locking component 5 (as Figure 3 shown).

[0076] The display component 3 includes a display screen 31 and two rotating shafts 32 extending from the display screen 31. The two rotating shafts 32 are arranged to have the same axial direction X. In this embodiment, the axial direction X of the two rotating shafts 32 is substantially parallel to the width direction of the vehicle 1. In one embodiment, one rotating shaft 32 is rotationally engaged with a carrying beam 201 that carries the display device 2, and the other rotating shaft 32 is connected to the driving component 4. Thus, under the drive of the driving component 4, the display screen 31 is adapted to rotate between a locked position A1 parallel to the vehicle roof panel 11 (i.e., along the horizontal direction H) and a use position A2 away from the vehicle roof panel 11 (as Figure 1 shown).

[0077] The locking component 5 is adapted to be driven by the driving component 4 to move to engage or disengage from the display screen 31. For example, when the display screen 31 is in the locked position A1, the locking component 5 engages with the display screen 31 to hold the display screen 31 in the locked position A1 (as Figure 3 shown). When the display screen 31 starts to rotate from the locked position A1 towards the use position A2, the locking component 5 disengages from the display screen 31.

[0078] As Figure 5As shown, the driving component 4 is located on the side of the display screen 31 along the axial direction X of the rotating shaft 32, and the driving component 4 is adapted to drive the display screen 31 to rotate and drive the locking component 5 to move. Specifically, the driving component 4 includes a guide rail plate 44, a moving seat 41, and a link mechanism 42.

[0079] The guide rail plate 44 is arranged along the horizontal direction H and is configured with a slideway 441. The slideway 441 is substantially perpendicular to the axial direction X of the rotating shaft 32.

[0080] The moving seat 41 is connected to the locking component 5. The moving seat 41 is arranged on the slideway 441 and is adapted to reciprocate along the slideway 441 to drive the locking component 5 to move.

[0081] One end of the link mechanism 42 is hinged to the moving seat 41, and the other end is fixedly connected to the rotating shaft 32. In this way, when the moving seat 41 moves on the slideway 441, it can drive the link mechanism 42 to rotate, and then drive the rotating shaft 32 (or the display screen 31) to rotate.

[0082] According to the display device 2 of the present application, when the display screen 31 is in the locked position A1, the moving seat 41 is in the first position in the slideway 441, and the locking component 5 is engaged with the display screen 31. When the moving seat 41 moves from the first position towards the second position, the locking component 5 is driven by the moving seat 41 to move away from the display screen 31. At the same time, the moving seat 41 drives the link mechanism 42 and the rotating shaft 32 to rotate, and then drives the display screen 31 to rotate from the locked position A1 towards the use position A2. When the moving seat 41 moves to the second position, the display screen 31 moves to the use position A2. When the moving seat 41 moves from the second position towards the first position, similar to the above description, the link mechanism 42 and the rotating shaft 32 will rotate accordingly, and then the display screen 31 rotates from the use position A2 towards the locked position A1. When the moving seat 41 moves to the first position, the locking component 5 is driven by the moving seat 41 to move into engagement with the display screen 31. Overall, in the display device 2 of the present application, the rotation of the display screen 31 and the movement of the locking component 5 are driven by the same moving seat 41. In this way, there is no need to configure an additional locking brake for the display device 2, which helps to reduce the costs of the display device 2 and the vehicle 1.

[0083] In addition, as Figure 2 and Figure 4As shown, in the display device 2 of the present application, the driving assembly 4 is only connected to the display screen 31 through the rotating shaft 32 and moves independently of the display screen 31. Overall, the driving assembly 4 is formed as a module independent of the display screen 31. When the display device 2 is installed on the vehicle roof panel 11, the driving assembly 4 can be spaced apart from and hidden behind the display screen 31, which does not interfere with the movement of the display screen 31. For example, the carrying beam 201 is configured as a double-layer structure with an internal space; the driving assembly 4 is disposed within this internal space, and the rotating shaft 32 extends into this internal space to connect with the driving assembly 4. The hidden driving assembly 4 helps prevent foreign objects from entering the driving assembly 4, thereby protecting the driving assembly 4, and also helps prevent users from coming into contact with the driving assembly 4 to avoid harm to the users. Additionally, the hidden driving device 4 is basically not visible from the outside, which helps improve the aesthetics of the vehicle 1.

[0084] In one embodiment, also as Figure 3 shown, a locking hole 312 is formed on the back surface of the display screen 31 (i.e., the surface facing away from the screen of the display screen 31). In this way, the locking assembly 5 is disposed at the back surface of the display screen 31 to be adapted to engage or disengage with the locking hole 312.

[0085] In one embodiment, also as Figure 2 、 Figure 3 and Figure 4 shown, the display screen 31 is, for example, a flat panel display screen to reduce the space occupied by the display screen 31. The shape of the display screen 31 is, for example, generally rectangular. The rotating shaft 32 is disposed along one length edge of the rectangle (i.e., the axial direction X of the rotating shaft 32 is generally parallel to the length edge of the rectangle). The driving assembly 4 is disposed corresponding to the width edge of the rectangle, for example, on the side of the display screen 31 along the length direction of the display screen 31. When the display screen 31 is in the locked position A1, the slideway 441 is generally parallel to the width edge of the rectangle. Of course, the display screen 31 can also be of other shapes. For simplicity, in the present application, the technical solution of the present application is described by taking the display device 2 shown in Figure 2 、 Figure 3 and Figure 4 as an example.

[0086] In one embodiment, the display 31 is configured such that in the locked position A1, the screen of the display 31 faces away from the vehicle roof panel 11.

[0087] Optionally, as Figure 5As shown, the linkage mechanism 42 includes a first link 421 and a second link 422. The first end 423 of the first link 421 is fixedly connected to the rotating shaft 32, and the first end 424 of the second link 422 is hinged to the moving seat 41. The second end 425 of the first link 421 is hinged to the second end 426 of the second link 422. In addition, the first link 421 and the second link 422 are adapted to rotate in a vertical plane. According to this linkage mechanism 42, when the moving seat 41 moves between a first position and a second position along the slideway 441, the distance between the moving seat 41 and the rotating shaft 32 changes, so that the linkage mechanism 42 rotates in the vertical plane (as shown in Figure 12 and Figure 13 shown), thereby driving the rotation of the rotating shaft 32 (and the display screen 31). The structure of this linkage mechanism 42 is simple, with a small volume and low cost, which helps to reduce the overall size of the drive assembly 4, and thus facilitates the installation of the drive assembly 4 in a narrow space, and helps to reduce the costs of the display device 2 and the vehicle 1. It should be understood that those skilled in the art can also use other types of linkage mechanisms, which will not be elaborated here.

[0088] In one embodiment, as shown in Figure 4 shown, the first link 421 is arranged to be parallel to the display screen 31 and perpendicular to the axial direction X of the rotating shaft 32. For example, the first link 421 is parallel to a width edge of the display screen 31. In this way, the angle between the second link 422 and the first link 421 is equal to the angle between the second link 422 and the display screen 31.

[0089] As shown in Figure 12As shown, the linkage mechanism 42 is configured such that when the display screen 31 is in the locked position A1 in the horizontal direction H, the first link 421 is also in the generally horizontal direction H, and the second link 422 is above the first link 421 in the vertical direction Z and forms a first included angle α1 greater than 90 degrees with the first link 421. In one embodiment, the first included angle α1 is less than 100 degrees, such as 95 degrees, 96 degrees, etc. Thus, when the moving seat 41 moves along the slideway 441 from the first position to the second position, the moving seat 41 first drives the second link 422 to rotate (for example, clockwise) until it is perpendicular to the first link 421, and presses the second end 425 of the first link 421 downward (i.e., in the direction away from the vehicle roof 11). Under the lever action, the display screen 31 will slightly rotate upward in the vertical direction Z (i.e., slightly counterclockwise toward the vehicle roof 11). In this way, the locking hole 312 of the display screen 31 no longer contacts the locking assembly 5 tightly, but a gap is generated between the two. At this time, the moving seat 41 drives the locking assembly 5 to retract from the locking hole 312 to separate from the display screen 31. Since there is a gap between the locking assembly 5 and the locking hole 312, the resistance to the retraction movement of the locking assembly 5 is small, which helps the locking assembly 5 to move smoothly. Next, the display screen 31 continues to rotate clockwise until it reaches the use position A2.

[0090] When the moving seat 41 moves along the slideway 441 from the second position to the first position, the moving seat 41 drives the second link 422 to rotate counterclockwise and drives the second end 425 of the first link 421 to rotate counterclockwise. As a result, the display screen 31 rotates counterclockwise and upward from the use position A2. After the display screen 31 moves to the horizontal direction H, the second link 422 continues to rotate slightly counterclockwise and presses the second end 425 of the first link 421 downward. The display screen 31 thus continues to rotate slightly counterclockwise and upward, making the locking hole 312 face the locking assembly 5. At this time, the moving seat 41 drives the locking assembly 5 to move into the locking hole 312 to be combined with the locking hole 312 (or the display screen 31). It should also be noted that after the display screen 31 rotates slightly counterclockwise from the horizontal direction H, not only does the locking hole 312 face the locking assembly 5, but also when the locking assembly 5 is inserted into the locking hole 312, there is a gap between the locking hole 312 and the locking assembly 5, which helps to reduce the resistance of the locking assembly 5 to be inserted into the locking hole 312.

[0091] In one embodiment, as Figure 13As shown, when the display screen 31 is in the use position A2, the second link 422 is in a generally horizontal direction H, and the first link 421 is below the second link 422 in the vertical direction Z and forms a second included angle α2 less than 90 degrees with the second link 422. Overall, the first link 421 and the display screen 31 are in a generally inclined state to facilitate the rear row passengers to view the picture on the display screen 31. In one embodiment, when the display screen 31 is in the use position A2, the second included angle α2 can also be equal to 90 degrees, which will not be elaborated here.

[0092] In one embodiment, the length of the first link 421 is between 15 mm and 20 mm, for example, the length is 17 mm or 18 mm, and the length of the second link 422 is equal to the length of the first link 421. Overall, the first link 421 and the second link 422 with such lengths help to make the overall size of the drive assembly 4 smaller, so as to facilitate the installation of the drive assembly 4 in a narrow space. It is also found that by using the first link 421 and the second link 422 with such lengths, when the display screen 31 rotates counterclockwise from the use position A2 and approaches the locking position A1 (for example, when the included angle between the display screen 31 and the horizontal direction H is between 0 degrees and 30 degrees), the output power of the motor 43 (described below) of the drive assembly 4 is basically constant, and the current is also basically constant. When the display screen 31 is blocked by an obstacle (for example, a hand is pinched between the display screen 31 and the vehicle roof panel 11), the current of the motor 43 will suddenly increase, and this sudden increase is easy to be monitored. Then, the motor 43 can be commanded to stop or reverse, so as to remove the obstacle (for example, move the hand away from the display screen 31). This helps to avoid damage to the display device 2 and also helps to avoid pinching of the hand.

[0093] Optionally, also as Figure 5 shown, two sliding grooves are formed on the guide rail plate 44, and these two sliding grooves form the slideway 441 of the moving seat 41.

[0094] Also as Figure 6 shown, the moving seat 41 includes a main body 414 and two groups of sliding feet 415 extending from the main body 414. The two groups of sliding feet 415 are inserted into the corresponding sliding grooves and are adapted to slide along the corresponding sliding grooves. According to this structure, the two groups of sliding feet 415 help to improve the overall stability of the moving seat 41, thereby helping to improve the stability of the display screen 31 and thus improving the user experience. It should be understood that according to the actual situation, other numbers of sliding feet 415 can also be set, which will not be elaborated here. It should also be understood that the first end 424 of the second link 422 is hinged to the main body 414.

[0095] In one embodiment, the moving seat 41 is connected to the locking assembly 5 through a flexible cable 525 to drive the locking assembly 5 to move. The cable 525 can be deformed to be suitable for installation in a space with a complex and tortuous shape. In addition, the locking assembly 5 can be spaced apart from the moving seat 41 as long as the cable 525 can be arranged, which also facilitates the setting of the display device 2 in a narrow space.

[0096] Optionally, as also Figure 6 shown, an elastic sliding sleeve 416 is provided on each sliding foot 415. The sliding sleeve 416 is in sliding contact with the sliding groove. In this way, when the size of the sliding foot 415 is slightly deviated from the standard size, the deviation can be absorbed by the deformation of the sliding sleeve 416 to smoothly insert the sliding foot 415 into the sliding groove. In addition, the frictional resistance between the sliding sleeve 416 and the sliding groove is small, which helps to reduce the movement resistance of the moving seat 41. In one embodiment, the sliding sleeve 416 can be made of rubber.

[0097] Optionally, as also Figure 5 shown, the driving assembly 4 further includes a motor 43, and the output shaft of the motor 43 is a lead screw 433. The main body 414 of the moving seat 41 is in threaded cooperation with the lead screw 433. In this way, when the lead screw 433 rotates, the moving seat 41 will move along the axial direction of the lead screw 433, and then drive the locking assembly 4 to move and drive the rotating shaft 32 (or the display screen 31) to rotate. According to this structure, the threaded cooperation between the main body 414 and the lead screw 433 makes the movement accuracy of the moving seat 41 high and the movement stable, which helps the display screen 31 to rotate precisely and smoothly between the locking position A1 and the use position A2.

[0098] In one embodiment, as also Figure 5 shown, a first limit block 431 and a second limit block 432 are provided on the lead screw 433, and the first limit block 431 and the second limit block 432 are spaced apart along the axial direction of the lead screw 433. The main body 414 moves within the range defined by the first limit block 431 and the second limit block 432. According to this structure, the distance between the first limit block 431 and the second limit block 432 defines the stroke range of the moving seat 41, and the first limit block 431 and the second limit block 432 respectively define the first position and the second position in the sliding track 441 of the moving seat 41. The first limit block 431 and the second limit block 432 can also prevent the moving seat 41 from moving excessively and disengaging from the lead screw 433, and can ensure that the display screen 31 rotates within a preset angle range (i.e., between the locking position A1 and the use position A2).

[0099] In one embodiment, as Figure 5 and Figure 6As shown, the moving seat 41 further includes a connecting block 417. The connecting block 417 is fixedly connected to the main body 414 and is in threaded engagement with the lead screw 433. For example, a threaded hole 418 matching the lead screw 433 is formed in the connecting block 417, and thus the connecting block 417 is sleeved on the lead screw 433. In other embodiments, the main body 414 can also be directly in threaded engagement with the lead screw 433, which will not be elaborated here.

[0100] Next, the locking assembly 5 will be described.

[0101] As Figure 8 shown, the locking assembly 5 includes a locking tongue plate 51 and a guide member 52 driven by the moving seat 41. As Figure 9 shown, a first guide groove 513 is formed in the locking tongue plate 51. The first guide groove 513 includes a straight section 514 parallel to the axial direction X of the rotating shaft 32 and an inclined section 515 connected to the straight section 514 and forming an obtuse angle. Also as Figure 9 shown, the inclined section 515 can be located on the front side of the straight section 514 along the retracting direction D1 in which the locking tongue plate 51 moves away from the locking hole 312. In other embodiments, the inclined section 515 can also be located on the rear side of the straight section 514 along the retracting direction D1. For simplicity, in this application, only the Figure 9 shown locking tongue plate 51 is taken as an example to describe the technical solution of this application.

[0102] The guide member 52 is in sliding engagement with the first guide groove 513 and is adapted to reciprocate in a direction parallel to the axial direction X of the rotating shaft 32 under the drive of the moving seat 41. Overall, the movement direction of the guide member 52 is parallel to the straight section 514 and not parallel to the inclined section 515.

[0103] When the display screen 31 is in the locked position A1, the guide member 52 is within the inclined section 515, and the locking tongue plate 51 is engaged in the locking hole 312. When preparing to use the display screen 31, first rotate the display screen 31 slightly upward in the vertical direction Z from the locked position A1 (as described above). The guide member 52 moves from the inclined section 515 towards the straight section 514 under the drive of the moving seat 41, and thus applies a first thrust force along the retracting direction D1 to the locking tongue plate 51. Under the action of the first thrust force, the locking tongue plate 51 moves out of the locking hole 312 and separates from the display screen 31. After the locking tongue plate 51 separates from the display screen 31, the guide member 52 moves into the straight section 514, and the display screen 31 rotates towards the use position A2. As the display screen 31 rotates towards the use position A2, the guide member 52 continues to move away from the inclined section 515 within the straight section 514. Since the extending direction of the straight section 514 is parallel to the movement direction of the guide member 52, when the guide member 52 moves along the straight section 514, the guide member 52 does not push the locking tongue plate 51 towards or away from the locking hole 312.

[0104] When the display screen 31 is retracted and rotated from the use position A2 towards the locking position A1, the guide member 52 moves from the straight section 514 towards the inclined section 515 under the drive of the moving seat 41. When the display screen 31 rotates to the horizontal direction H, the guide member 52 moves from the straight section 514 into the inclined section 515. When the display screen 31 continues to rotate slightly upward in the vertical direction Z (as described above), the guide member 52 moves away from the straight section 514 within the inclined section 515, and thus exerts a second thrust force in the extending direction D2 opposite to the retracting direction D1 on the locking tongue plate 51 (i.e., the direction of the second thrust force is towards the locking hole 312). In this way, the locking tongue plate 51 gradually inserts into the locking hole 312 and engages with the display screen 31 together.

[0105] In a specific embodiment, as Figure 9 shown, the locking tongue plate 51 includes a plate body 511 and a locking tongue 512 extending from the plate body 511. In this case, the first guide groove 513 is formed on the plate body 511. Those skilled in the art can also construct the locking tongue plate 51 in other forms according to the actual situation, which will not be elaborated here.

[0106] Optionally, as also Figure 8 and Figure 10 shown, the locking assembly 5 further includes a bracket plate 53, on which a second guide groove 532 parallel to the axial direction X of the rotating shaft 32 is formed. The length of the second guide groove 532 matches the length of the first guide groove 513. In the assembled state of the locking assembly 5, the bracket plate 53 is stacked on the locking tongue plate 51, and the second guide groove 532 is basically corresponding to the first guide groove 513. In this case, the guide member 52 is in sliding fit with the second guide groove 532 and is adapted to reciprocate along the second guide groove 532. In this way, the second guide groove 532 defines the movement range of the guide member 52 and ensures that the guide member 52 can only move in a direction parallel to the axial direction X of the rotating shaft 32, which helps the guide member 52 to exert a thrust force on the locking tongue plate 51.

[0107] Optionally, as also Figure 9 and Figure 10As shown, two third guiding grooves 516 are formed on the locking tongue plate 51. The extending directions of the two third guiding grooves 516 are parallel to the moving direction of the locking tongue plate 51, and are located on both sides of the first guiding groove 513 along the extending direction of the first guiding groove 513. Two guiding ribs 531 are formed on the bracket plate 53. The two guiding ribs 531 are respectively in sliding fit with the corresponding third guiding grooves 516. According to this structure, the guiding ribs 531 and the third guiding grooves 516 restrict the locking tongue plate 51 to move only along the retracting direction D1 and the extending direction D2, and will not deflect, so as to ensure that the locking tongue plate 51 can be smoothly inserted into or move out of the locking hole 312. It should be understood that other numbers of third guiding grooves 516 and guiding ribs 531 can also be provided. In addition, the third guiding grooves 516 can also be provided on the bracket plate 53, and correspondingly, the guiding ribs 531 are provided on the locking tongue plate 51.

[0108] Optionally, as Figure 8 and Figure 11 shown, the locking assembly 5 further includes a first housing 501. The first housing 501 is arranged on the side of the bracket plate 53 facing away from the locking tongue plate 51. For example, the first housing 501 basically covers the bracket plate 53, and a receiving space 503 is formed between the first housing 501 and the bracket plate 53. A fourth guiding groove 504 corresponding to the second guiding groove 532 is formed on the first housing 501.

[0109] The guiding member 52 includes a slider 523, and a first pin 521 and a second pin 522 extending from the slider 523. The slider 523 is located in the receiving space 503. The first pin 521 extends through the second guiding groove 532 into the first guiding groove 513 and is in sliding fit with the first guiding groove 513 and the second guiding groove 532. The second pin 522 is in sliding fit in the fourth guiding groove 504. In this way, the second guiding groove 532 and the fourth guiding groove 504 restrict the slider 523 to reciprocate only in a direction parallel to the axial direction X of the rotating shaft 32. In addition, the first housing 501 also plays a role in protecting the bracket plate 53 and the guiding member 52.

[0110] In addition, the slider 523 is fixedly connected to the cable 525 (as Figure 8 shown), so as to facilitate the moving seat 41 to drive the slider 523 (or the guiding member 52) to move.

[0111] In one embodiment, as Figure 8 and Figure 11 shown, the locking assembly 5 further includes a second housing 502. The second housing 502 is located on the side of the locking tongue plate 51 facing away from the bracket plate 53. In this way, the locking tongue plate 51 and the bracket plate 53 are between the first housing 501 and the second housing 502, which plays a role in protecting the locking tongue plate 51, the bracket plate 53 and the guiding member 52.

[0112] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and variations can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
