[0066] 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. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0067] In the present application, the term "horizontal direction" refers to a direction generally parallel to the ground; the term "vertical direction" refers to a direction generally perpendicular to the vehicle roof or the horizontal direction. The term "longitudinal direction of the vehicle" refers to a direction generally along the length direction of the vehicle.

[0068] Figure 1 Schematically shows a vehicle 1 according to an embodiment of the present application. AsFigure 1 As shown, a display device 2 for the vehicle roof is mounted on the vehicle roof 11 of the passenger compartment of the vehicle 1 (hereinafter, simply referred to as the display device 2). For example, the display device 2 is located between the front row seat 12 and the rear row seat 13 to provide entertainment for the rear passengers.

[0069] The display device 2 will be described below.

[0070] As Figure 2 and Figure 3 shown, the display device 2 includes a display component 3 and a driving component 4.

[0071] The display component 3 includes a display 31 and two rotating shafts 32 extending from the display 31. For example, the axial direction X of the two rotating shafts 32 is generally parallel to the width direction of the vehicle 1. The number of the driving components 4 is two and they are located on both sides of the display 31 along the axial direction X of the rotating shaft 32 to be respectively connected to the corresponding rotating shafts 32. In this way, under the drive of the driving component 4, the display 31 is adapted to rotate between a locked position A1 parallel to the vehicle roof 11 (i.e., along the horizontal direction H) and a use position A2 away from the vehicle roof 11 (as Figure 1 shown), and can also perform translational movement along the longitudinal direction of the vehicle 1, and can also perform translational movement while rotating (as described below). It should be understood that, according to the actual situation, only one driving component 4 can also be provided, which will not be elaborated here.

[0072] As Figure 4 and Figure 5 shown, the driving component 4 includes a guide rail plate 40, a first moving seat 41, a second moving seat 42 and a link mechanism 43. Specifically, the guide rail plate 40 is generally arranged along the horizontal direction H. The guide rail plate 40 is configured with a first slide way 401 and a second slide way 402 (as Figure 8 shown). The first slide way 401 and the second slide way 402 are parallel to each other and extend along the longitudinal direction L perpendicular to the axial direction X. For example, the longitudinal direction L is generally parallel to the front-rear direction of the vehicle 1.

[0073] The first moving seat 41 is arranged on the first slide way 401 and is adapted to reciprocate along the first slide way 401. The rotating shaft 32 is rotatably connected to the first moving seat 41.

[0074] The second moving seat 42 is arranged on the second slide way 402 and is adapted to reciprocate along the second slide way 402.

[0075] The first end of the link mechanism 43 is hinged to the second moving seat 42, and the second end is fixedly connected to the rotating shaft 32.

[0076] According to the display device 2 of the present application, the rotating shaft 32 of the display 31 is directly connected to the first moving seat 41 and is indirectly connected to the second moving seat 42 through the link mechanism 43.

[0077] When the first moving seat 41 and the second moving seat 42 move synchronously along the longitudinal direction L (i.e., the moving speed of the first moving seat 41 is equal to that of the second moving seat 42 and the directions are the same), the rotating shaft 32 also moves synchronously with the first moving seat 41 and the second moving seat 42. In this way, the distance between the rotating shaft 32 and the second moving seat 42 does not change, so that the link mechanism 43 does not rotate, and the rotating shaft 32 and the display 31 do not rotate accordingly. Overall, the rotating shaft 32 and the display 31 translate along the longitudinal direction L as the first moving seat 41 and the second moving seat 42 move, which realizes the adjustment of the distance between the display 31 and the rear row passengers. It should be noted that the display 31 can be driven by the first moving seat 41 and the second moving seat 42 to translate along the longitudinal direction L both when it is in the use position A2 or the locking position A1.

[0078] When the second moving seat 42 and the first moving seat 41 move asynchronously as follows, that is, one of the second moving seat 42 and the first moving seat 41 moves along the longitudinal direction L while the other stops, the distance between the second moving seat 42 and the rotating shaft 32 (or the display 31) will change. In this way, the link mechanism 43 will rotate, and the rotating shaft 32 is driven by the link mechanism 43 to rotate, so that the display 31 rotates accordingly. For example, the display 31 rotates downward from the locking position A1 to the use position A2 or rotates upward from the use position A2 to the locking position A1.

[0079] When the first moving seat 41 and the second moving seat 42 move asynchronously as follows, that is, the first moving seat 41 and the second moving seat 42 move along the longitudinal direction L, but the moving speeds are not equal, the rotating shaft 32 rotates while translating along the longitudinal direction L, so that the display 31 also rotates while translating along the longitudinal direction L, thereby realizing the adjustment of the distance between the display 31 and the rear row passengers while the display 31 rotates.

[0080] It can be seen from this that according to the display device 2 of the present application, the driving component 4 enables the display 31 to rotate between the locking position A1 and the use position A2, and can also adjust the distance between the display 31 and the rear row passengers, which facilitates the user to use the display device 2.

[0081] In addition, according to the display device 2 of the present application, the driving component 4 is only connected to the display 31 through the rotating shaft 32, and the first moving seat 41 and the second moving seat 42 move independently of the display 31. Overall, the driving component 4 is formed as a module independent of the display 31. When the display device 2 of the present application is installed on the vehicle roof panel 11, the driving component 4 can be arranged at an interval from the display 31 and hidden, which will not interfere with the movement of the display 31. As Figure 4As shown, the drive assembly 4 is separated from the display 31 by a partition 310 and is shielded by a frame 33. This helps prevent foreign objects from entering the drive assembly 4, thereby protecting the drive assembly 4, and also helps prevent personnel from coming into contact with the drive assembly 4 to avoid harm to personnel. Additionally, the drive device 4 is substantially not visible from the outside, which helps improve the aesthetics of the vehicle 1.

[0082] In one embodiment, as Figure 2 and Figure 3 shown, the display 31 can be, for example, a flat panel display to reduce the space occupied by the display 31. For example, the shape of the display 31 is 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 guide rail plate 40 is disposed corresponding to the width edge of the rectangle. When the display 31 is in the locked position A1, the width edge of the rectangle is generally parallel to the longitudinal direction L, and the first slideway 401 and the second slideway 402 are also generally parallel to the width edge of the rectangle. Of course, the display 31 can also be of other shapes. For simplicity, in this application, the technical solution of this application is described by taking the display 31 having a generally rectangular shape and the display 31 being arranged such that its length edge (or, the axial direction X of the rotating shaft 32) is generally parallel to the width direction of the vehicle 1 as an example.

[0083] In one embodiment, the display 31 is configured such that in the locked position A1, the screen of the display 31 faces the vehicle roof panel 11. In this way, after the display 31 is retracted to the locked position A1, it is difficult to touch the display screen of the display 31, which protects the display 31.

[0084] Optionally, as also Figure 2 and Figure 3 shown, the display device 2 further includes a frame 33 surrounding the display 31. A fixed locking tongue 333 extending towards the display 31 is formed on the frame 33. A locking hole 311 matching the fixed locking tongue 333 is formed on the display 31. For example, the frame 33 includes two frame bars (i.e., the first frame bar 331 and the second frame bar 332) disposed corresponding to the two length edges of the display 31. The first frame bar 331 is away from the rotating shaft 32 and is provided with the fixed locking tongue 333, and the locking hole 311 is formed on the length edge of the display 31 away from the rotating shaft 32. When the display 31 is in the locked position A1, the display 31 can be driven to translate towards the first frame bar 331 and the locking hole 311 can be engaged with the fixed locking tongue 333 by the synchronous movement of the first moving seat 41 and the second moving seat 42, thereby realizing the locking of the display 31. According to this structure, the display device 2 does not need to provide an additional locking driver to drive the display or the locking tongue, which helps reduce the costs of the display device 2 and the vehicle 1.

[0085] In one embodiment, as Figure 3 shown, two fixed locking tongues 333 are provided, and the two fixed locking tongues 333 are close to both ends of the first frame bar 331. This helps to stably lock the display 31. In other embodiments, other numbers of fixed locking tongues may also be provided, which will not be elaborated here.

[0086] Optionally, as Figure 2 shown, a cover plate 334 extending along the axial direction X of the rotating shaft 32 is further provided on the frame 33. The cover plate 334 is on the opposite side of the fixed locking tongue 333 and is rotatably connected to the frame 33. The cover plate 334 can rotate in accordance with the rotation of the display 31 and cover the gap between the display 31 and the frame 33. For example, the cover plate 334 is rotatably connected to the second frame bar 332. In this way, the cover plate 334 covers the gap between the display 31 and the second frame bar 332 (as Figure 2 shown), so as to prevent foreign objects from entering the display device 2 and help to improve the aesthetics of the display device 2.

[0087] In one embodiment, the cover plate 334 is connected to the second frame bar 332 through a torsion spring (not shown in the figure). In this way, when the display 31 rotates from the locked position A1 towards the use position A2, the display 31 will push the cover plate 334 to rotate and compress the torsion spring. When the display 31 rotates from the use position A2 towards the locked position A1, the torsion spring drives the cover plate 334 to rotate along with the rotation of the display 31. This ensures that the cover plate 334 always covers the gap between the display 31 and the second frame bar 332.

[0088] In one embodiment, two motors 403 (such as Figure 2 and Figure 3 ) can be used to drive the first moving seat 41 and the second moving seat 42 to move respectively, so that the first moving seat 41 and the second moving seat 42 can move synchronously or asynchronously. In one embodiment, the motor 403 and the corresponding first moving seat 41 or second moving seat 42 are driven by a transmission chain 404 (such as Figure 5 shown). In this way, the motor 403 can be set at any appropriate position according to needs without having to be adjacent to the first moving seat 41 or the second moving seat 42, which facilitates the setting of the motor 403 in a narrow space. In one embodiment, the motor 403 can be set on the frame 33 and away from the first moving seat 41 and the second moving seat 42.

[0089] Optionally, as Figure 4As shown, the linkage mechanism 43 includes a first link 431 and a second link 432. The first link 431 is fixedly connected to the rotating shaft 32, and the second link 432 is hinged to the second moving seat 402. The first link 431 and the second link 432 are hinged and adapted to rotate in a vertical plane. The structure of this linkage mechanism 43 is simple and has a small volume, which helps to reduce the overall size of the driving assembly 4, and thus facilitates the installation of the driving assembly 4 in a narrow space. In addition, the cost of this linkage mechanism 43 is also relatively low, which 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.

[0090] Optionally, as Figure 10 and Figure 11 shown, a first included angle α1 greater than or equal to 90 degrees is formed between the first link 431 and the display 31. In one embodiment, the angle of the first included angle α1 can be 100 degrees, 110 degrees, 120 degrees, etc.

[0091] Also as Figure 10 shown, when the display 31 is in the locked position A1, the linkage mechanism 43 is configured such that the second link 432 is in the horizontal direction H, the first link 431 is below the second link 432 along the vertical direction Z and forms a second included angle α2 equal to the first included angle α1 with the second link 432. In this way, the display 31 is also in a generally horizontal direction H.

[0092] Also as Figure 11 shown, when the display 31 is in the use position A2, the first link 431 is generally in the horizontal direction H, and the second link 432 is above the first link 431 along the vertical direction Z and is in a generally vertical direction Z. Since the first angle α1 is greater than 90 degrees, in the use position A2 of the display 31, the display 31 is in an inclined state as a whole, which helps the rear row passengers to more clearly view the screen of the display 31, thereby improving the viewing experience of the rear row passengers.

[0093] Also according to this setting method of the linkage mechanism 43, it is found that in the initial stage when the display 31 rotates from the locked position A1 towards the use position A2 (for example, during the display 31 rotates clockwise from the locked position A to a position at an 85-degree angle with the horizontal direction H), the rotation speed of the display 31 is relatively fast to facilitate the quick opening of the display 31; while when the display 31 approaches the use position A2 (for example, during the display 31 rotates clockwise from a position at an 85-degree angle with the horizontal direction H to a position at an 110-degree angle with the horizontal direction H), the rotation speed of the display 31 will gradually slow down, which helps to accurately control and / or accurately adjust the final angle of the display 31 to provide a better viewing experience for the rear row passengers.

[0094] In addition, according to the arrangement of the link mechanism 43, when the display 31 is in the use position A2 (eg Figure 11 As shown in the figure, since the first connecting rod 431 is in a substantially horizontal direction H and the second connecting rod 432 is in a substantially vertical direction Z. If the display 31 is accidentally subjected to a first thrust F1 in the horizontal direction H, the first connecting rod 431 will apply a second thrust F2 in the vertical direction H to the second connecting rod 432 (i.e., the direction of the second thrust F2 is perpendicular to the guide plate 40). Under the obstruction of the guide plate 40, the second connecting rod 432 will not rotate, and the first connecting rod 431 will not rotate either, thereby preventing the display 31 from accidentally rotating. It should be noted that when the display 31 is in the use position A2, even if the second connecting rod 432 deviates slightly from the vertical direction Z, the resistance applied by the guide plate 40 and the locking force applied by the transmission chain 404 are sufficient to prevent the second connecting rod 432 from rotating, thereby preventing the display 31 from rotating.

[0095] In one embodiment, the length of the first connecting rod 431 is between 15 mm and 20 mm, and the length of the second connecting rod 432 is between 25 mm and 30 mm. The first connecting rod 431 and the second connecting rod 432 of 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. In addition, it is also found that by using the first connecting rod 431 and the second connecting rod 432 of such lengths, when the display 31 rotates counterclockwise from the use position A2 to the locking position A1 (for example, when the angle between the display 31 and the horizontal direction H is between 0 degrees and 30 degrees), the output power of the motor 403 is substantially constant, and the current is also substantially constant. When the display 31 is blocked by an obstacle (for example, a hand is clamped between the display 31 and the guide plate 40), the current of the motor 403 will suddenly increase, and the sudden increase is easy to be monitored, and then the motor 403 can be instructed to stop or reverse, so as to eliminate the obstacle (for example, move the hand away from the display 31). This helps to avoid damage to the display device 2 and helps to avoid hand injuries.

[0096] Optionally, as shown in FIG. 9 , a shaft hole 414 is configured on the first moving seat 41 , and the shaft hole 414 extends substantially along the axial direction X of the rotating shaft 32 . Figure 7 As shown, the rotating shaft 32 includes a rotating shaft body 320. The rotating shaft body 320 is suitable for being inserted into the shaft hole 414, and the first connecting rod 431 is fixedly connected to the rotating shaft body 320. This realizes the rotation connection between the rotating shaft 32 and the first moving seat 41.

[0097] In one embodiment, Figure 7As shown, the rotating shaft 32 further includes a support plate 323 fixedly connected to the rotating shaft body 320. The support plate 323 is fixedly connected to the display 31 so as to facilitate the synchronous movement of the rotating shaft 32 and the display 31. In one embodiment, the first link 431, the rotating shaft body 320 and the support plate 323 are integrally formed, which helps to simplify the manufacture of the link mechanism 43 and the rotating shaft 32.

[0098] Also as Figure 7 shown, a first flange 321 with a circumferential notch 322 is formed on the rotating shaft body 320. The central angle corresponding to the circumferential notch 322 is equal to the first included angle α1. As Figure 9a shown, a limiting block 417 is provided at the edge of the shaft hole 414. After the rotating shaft body 320 is inserted into the shaft hole 414, the limiting block 417 is within the range of the circumferential notch 322, and when the rotating shaft body 320 rotates, the limiting block 417 is adapted to contact both ends of the circumferential notch 322, thereby limiting the rotation angle of the rotating shaft body 320 (or the display 31). For example, when the display 31 is in the locked position A1, one end of the circumferential notch 322 contacts the limiting block 417; when the display 31 is in the use position A2, the other end of the circumferential notch 322 contacts the limiting block 417. In this way, the limiting block 417 and the circumferential notch 322 together limit the rotation angle of the rotating shaft 32 (or the display 31) to be equal to the first included angle α1. It should also be understood that it is easy for a technician in the art to set the limiting block 417 and the circumferential notch 322 such that the display screen 31 is in a substantially horizontal direction H in the locked position A1, which will not be elaborated here.

[0099] Optionally, as Figure 8 shown, two parallel first chutes are formed on the guide rail plate 40, and these two first chutes form a first slideway 401. As Figure 9a and Figure 9b shown, the first moving seat 41 includes a first main body 410 and two groups of first sliding feet 416 extending from the first main body 410. The two groups of first sliding feet 416 are parallel to each other and are respectively inserted into the corresponding first chutes and are adapted to slide along the first chutes. According to this structure, the two groups of first sliding feet 416 help to improve the overall stability of the first moving seat 41, which helps to improve the stability of the display 31 and further improve the user experience. It should be understood that according to the actual situation, other numbers of first sliding feet 416 can also be set, which will not be elaborated here.

[0100] In one embodiment, a stop block (not shown in the figure) is further provided in the first chute to limit the stroke range of the first moving seat 41.

[0101] Optionally, also as Figure 9a and Figure 9bAs shown, an elastic first sliding sleeve 412 is provided on each first sliding foot 416, and the first sliding sleeve 412 is in sliding contact with the first sliding groove. In this way, when the size of the first sliding foot 416 has a slight deviation compared with the standard size, the deviation can be absorbed by the deformation of the first sliding sleeve 412, so as to smoothly insert the first sliding foot 416 into the first sliding groove. In addition, the frictional force between the first sliding sleeve 412 and the first sliding groove is small, which helps to reduce the movement resistance of the first moving seat 41. In one embodiment, the first sliding sleeve 412 can be made of rubber.

[0102] It should be noted that, as also Figure 9a and Figure 9b shown, a first sliding sleeve 412 is connected to the corresponding drive chain 404 to facilitate driving the movement of the first moving seat 41 by the corresponding motor 403.

[0103] Also as Figure 9a and Figure 9b shown, the first main body 410 includes two first extension arms 411 that are parallel to each other and spaced apart, and a connecting portion 413 that connects the two first extension arms 411. The two first extension arms 411 are respectively formed with first sliding feet 416. Overall, the first main body 410 is generally formed in a U shape (as Figure 9b shown). In one embodiment, the first main body 410 can be integrally formed by bending a metal plate, which facilitates the manufacture of the first main body 410.

[0104] Through holes facing each other are formed on the two first extension arms 411, and these two through holes form the shaft hole 414 described above. In one embodiment, as Figure 9a and Figure 9b shown, a bushing 418 is installed in the shaft hole 414, and the rotating shaft body 320 extends rotatably through the bushing 418. The bushing 418 has a second flange 419 corresponding to the first flange 321 on the rotating shaft 32, and a limiting block 417 is formed on the second flange 419. According to this structure, the bushing 418 with the limiting block 417 can be manufactured separately, for example, by injection molding. For the first main body 410 with a relatively complex manufacturing process, this is very beneficial.

[0105] In one embodiment, as Figure 9b shown, a support block 415 is provided between the two first extension arms 411. The support block 415 can prevent the two first extension arms 411 from shaking relative to each other, which also helps to improve the stability of the first moving seat 41. In one embodiment, the rotating shaft body 320 extends through the support block 415 to prevent the support block 415 from detaching from the first main body 410.

[0106] Optionally, also as Figure 8As shown, two parallel second chutes are formed on the guide rail plate 40, and these two second chutes form the second slideway 402. Correspondingly, as Figure 6 shown, the second moving seat 42 includes a second main body 420 and two sets of second sliding feet 422 extending from the second main body 420. The two sets of second sliding feet 422 are parallel to each other and are respectively inserted into the corresponding second chutes and are adapted to move along the second chutes. Similar to the first moving seat 41, the second moving seat 42 with this structure also has good stability, which helps to improve the stability of the display 3. It should be noted that the link mechanism 43 (or the second link 432) is hinged to the second main body 420.

[0107] Optionally, also as Figure 6 shown, an elastic second sliding sleeve 423 is provided on the second sliding foot 422, and the second sliding sleeve 423 is in sliding contact with the second chute. Similar to the first moving seat 41, the second sliding sleeve 423 also helps to insert the second sliding foot 422 into the second chute and helps to reduce the movement resistance of the second moving seat 42. In addition, one second sliding sleeve 423 is connected to the corresponding drive chain 404 to facilitate driving the second moving seat 42 to move through the corresponding motor 403.

[0108] The above are only embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications 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.
