[0034] Please refer to Figure 1 And Figure 2 The embodiment provides a vehicle, which comprises a vehicle body 90 and a display device 100, and the display device 100 is installed in an in-vehicle space inside the vehicle body 90. With the orientation of the vehicle body 90 in the driving state as a reference, the advancing direction of the vehicle body 90 is front, the retreating direction is back, the left side of the driver is left, the right side of the driver is right, the ground direction is down, and the direction away from the ground is up. The vehicle body 90 has a vehicle body portion and a roof portion 91, the roof portion 91 is located above the vehicle body portion, and the vehicle body portion and the roof portion 91 jointly enclose an in-vehicle space for driving and riding, and the roof portion 91 can be provided with a sunroof or a sky curtain 911.

[0035] The display device 100 can be slidably connected to the roof portion 91 through a rotary driving member, that is, the roof portion 91 is provided with a slide rail, the rotary driving member is slidably connected to the slide rail, the display device 100 is connected to the rotary driving member, and the rotary driving member can drive the display device 100 to rotate between a storage position and a viewing position. Wherein, the extension direction of the slide rail can be the front-back direction. Of course, in other embodiments, the slide rail direction can also be the left-right direction or the inclined direction, which is not limited here.

[0036] The display device 100 has a display surface for displaying a picture. The thickness direction of the display device 100 is perpendicular to the display surface, the length direction of the display device 100 can be the left-right direction of the vehicle body 90, the width direction of the display device 100 is perpendicular to the thickness direction and the length direction of the display device 100, the length of the display device 100 is greater than the width, and the width is greater than the thickness, so as to form a flat structure. When the display device 100 is in the storage position, the display surface of the display device 100 is substantially parallel to the roof portion 91, and at this time, the display device 100 is close to the roof portion 91 to reduce the occupation of space; when the display device 100 is in the viewing position, the display surface of the display device 100 forms a preset angle with the roof portion 91, and the preset angle is an angle convenient for passengers to view. The roof portion 91 has an inner surface facing the interior space of the vehicle, and the display surface being substantially parallel to the roof portion 91 means that the angle between the display surface and the inner surface of the roof portion 91 is 0°-10°. The angle between the display surface and the roof portion 91 is the angle between the display surface and the inner surface of the roof portion 91 located at the rear side of the rotary drive. In order to improve the comfort of passengers viewing the display surface, the preset angle can be obtuse, so that the display surface faces downward and rearward, so as to facilitate the rear passengers to view the picture on the display surface by looking upward.

[0037] When it is needed to view the display device 100, such as Figure 1 , the display device 100 can be first driven to the middle position of the roof portion 91, that is, the obliquely upward position of the rear passengers, and then the display device 100 is driven by the rotary drive to rotate from the storage position to the viewing position, so that the rear passengers can view the picture on the display surface by looking upward. When it is not needed to view the display device 100, such as Figure 2 , the display device 100 can be driven by the rotary drive to rotate from the viewing position to the storage position to avoid blocking the view of the passengers and reduce the occupation of the interior space of the vehicle in the up-down direction, and then the display device 100 is driven to the rear side of the roof portion 91, so that the display device 100 can avoid the sunroof 911 or the sunroof when not in use, avoid affecting the field of view of the sunroof 911 or the sunroof, and leave the head area of the passengers to reduce the occupation of the space of the passenger use area of the interior space of the vehicle.

[0038] Optionally, the roof portion 91 has a set of slide rails, the set of slide rails includes two single slide rails, the two single slide rails are respectively arranged on the left and right sides of the sunroof 911 or the sunroof, and extend in the front-rear direction, and the two ends of the rotary drive are respectively connected to a single slide rail in a sliding manner.

[0039] Optionally, please refer to Figure 3The roof portion 91 is provided with two sets of slide rails arranged side by side in the left-right direction. Each set of slide rails is slidably connected with a rotating driving member. The display device 100 is provided with two display devices 100, and each display device 100 is connected with a rotating driving member. In this way, two display devices 100 can be arranged on the vehicle body 90 to facilitate the two rear passengers to watch the display devices 100 respectively.

[0040] In other embodiments, the roof portion 91 can not be provided with the sunroof or the sky screen 911, and the display device 100 can be arranged at a fixed position on the roof portion 91 and cannot be moved. This is not limited here.

[0041] Please refer to Figure 4 and Figure 5 , the embodiment also provides a display device 100, which comprises a device body 10 and a display module 20.

[0042] The device body 10 comprises a first shell 11 and a second shell 12. The first shell 11 has a first end 10a, and the second shell 12 has a second end 10b. The second shell 12 can move relative to the first shell 11 so that the second end 10b is close to or away from the first end 10a. The first end 10a and the second end 10b can be the two ends farthest away from each other on the first shell 11 and the second shell 12, respectively, i.e. the two ends in the width direction of the display device 100. The first shell 11 and the second shell 12 can be independently arranged or movably connected with each other.

[0043] Specifically, as shown in Figure 4 , when the second end 10b is close to the first end 10a, the second shell 12 is in a first position. When the second end 10b is away from the first end 10a, as shown in Figure 5 , the second shell 12 is in a second position. The second shell 12 can move between the first position and the second position. The second position can be a fixed position or any position away from the first position.

[0044] The first shell 11 and the second shell 12 jointly define a display opening 101. The area of the display opening 101 decreases when the second end 10b is close to the first end 10a, and the area of the display opening 101 increases when the second end 10b is away from the first end 10a. In this embodiment, the width of the display opening 101 is substantially equal to the distance between the first end 10a and the second end 10b, and the length of the display opening 101 is substantially equal to the length of the display device 100.

[0045] Please refer to Figure 6 and Figure 7The display module 20 comprises a winding structure 21, a winding belt 22 and a flexible screen 23. The winding structure 21 is connected to the second housing 12. The winding belt 22 is wound around the winding structure 21 and connected to the first housing 11. The flexible screen 23 is connected to the winding belt 22. When the driving mechanism drives the second end 10b to move away from the first end 10a, the winding structure 21 releases the winding belt 22, and at least the flexible screen 23 on the released winding belt 22 is exposed to the display opening 101. In some embodiments, the winding belt 22 is in a belt shape, and the flexible screen 23 is laid on the winding belt 22 and located on the side of the winding belt 22 facing the display opening 101. The flexible screen 23 can also be a touch screen, and can also not have a touch screen function. The surface of the flexible screen 23 exposed to the display opening 101 forms the display surface of the display device 100.

[0046] When the display device 100 needs to be stored, the second housing 12 can be driven to move to the first position, at which time the first end 10a is close to the second end 10b, the width of the display body is small, and the space occupation is reduced. When the display device 100 needs to be viewed, the second housing 12 can be driven to move towards the second position, at which time the display opening 101 gradually becomes larger, and the winding structure 21 releases the winding belt 22. The flexible screen 23 on the released winding belt 22 is exposed to the part of the display opening 101 that becomes larger. Thus, when the driving structure 13 drives the second housing 12 to move to the second position, the area of the part of the flexible screen 23 exposed to the display opening 101 is larger than the area of the part of the flexible screen 23 exposed to the display opening 101 when the second housing 12 is in the first position. Therefore, the area of the display surface of the display device 100 is increased, so that the passenger can have a large screen experience and the comfort of the passenger is improved.

[0047] In some embodiments, when the second housing 12 is in the first position, the display screen can be partially exposed to the display opening 101 to increase the area of the display surface viewed by the passenger. Of course, in other embodiments, when the second housing 12 is in the first position, the display opening 101 can also be in a closed state, or the display screen can completely avoid the display opening 101 to further reduce the volume of the equipment body 10, which is not limited herein.

[0048] In some embodiments, please refer to Figure 6 and Figure 7The device main body 10 further comprises a driving structure 13 connected to the first shell 11 and capable of driving the second shell 12 to move relative to the first shell 11 so as to move the second end 10b closer to or farther away from the first end 10a. That is, the driving structure 13 can drive the second shell 12 to move between the first position and the second position, and when it is needed to view the display device 100, the second shell 12 can be driven by the driving structure 13 to move from the first position toward the second position, and when it is needed to store the display device 100, the second shell 12 can be driven by the driving structure 13 to move toward the first position. The winding and releasing of the winding belt 22 are realized by the relative movement between the second shell 12 and the first shell 11, or can be realized by the driving of the storage structure by the driving structure 13. When the second shell 12 is driven to move between the first position and the second position, the winding belt 22 is always kept in tension so as to keep the flexible screen 23 flat.

[0049] In other embodiments, the movement of the second shell 12 relative to the first shell 11 and the winding and releasing of the winding belt 22 can also be realized manually, which is not limited here.

[0050] In some embodiments, the second shell 12 and the first shell 11 can be slidably connected to improve the stability of the device main body 10.

[0051] Specifically, referring to Figure 6 and Figure 7 , the first shell 11 comprises a shell body 111 and a support plate 112 connected thereto. The shell body 111 comprises a front shell plate 1111, a rear shell plate 1112 and a side shell plate 1113. The rear shell plate 1112 and the front shell plate 1111 are oppositely arranged and spaced apart in the thickness direction of the first shell 11, and the side shell plate 1113 is annularly arranged around the rear shell body and the front shell body. The rear shell plate 1112, the front shell plate 1111 and the side shell plate 1113 jointly form an installation cavity 102. The side shell plate 1113 comprises a first side portion, a second side portion 1113a and a third side portion connected in sequence. The second side portion 1113a is located at the first end 10a of the first shell 11. The first side portion and the third side portion are oppositely arranged in the length direction of the first shell 11. The edge of the first side portion away from the second side portion 1113a, the edge of the third side portion away from the second side portion 1113a, the edge of the front shell plate 1111 away from the second side portion 1113a and the edge of the rear shell plate 1112 away from the second side portion 1113a jointly form an aperture. The front shell plate 1111 is provided with a first display opening 1011 (in combination with Figure 4 ), which penetrates to the aperture.

[0052] The support plate 112 is located in the mounting cavity 102, and is close to and parallel to the front shell plate 1111. The support plate 112 has a support surface facing the first display opening 1011. The portion of the winding belt 22 that is not wound around the winding structure 21 can be located on the side of the support surface facing the first display opening 1011. The flexible screen 23 is located on the side of the winding belt 22 facing away from the support plate 112. The flexible screen 23 includes a first screen part 231 and a second screen part 232 connected to each other. The support plate 112 supports the first screen part 231. The first screen part 231 is exposed to the first display opening 1011. The second screen part 232 is wound around the winding structure 21 when the second shell 12 is in the first position, and is exposed to the second display opening 1012 when the second shell 12 is in the second position (in combination with Figure 5 ). The support plate 112 can support the first screen part 231 to prevent the first screen part 231 from sagging and affecting the viewing experience.

[0053] The second shell 12 includes a sliding body 121 and a limiting shell 122 connected to each other. The sliding body 121 is inserted into the mounting cavity 102 through the gap, and is in sliding connection with the shell body 111. The limiting shell 122 is located at the second end 10b of the second shell 12. When the second shell 12 is in the first position, the limiting shell 122 abuts against the shell body 111. When the second shell 12 slides toward the second position, the limiting shell 122 forms the second display opening 1012 with the front shell plate 1111. The second display opening 1012 gradually increases in size. The second display opening 1012 and the first display opening 1011 jointly form a display opening 101. When the second shell 12 reaches the second position, the display opening 101 is the largest. The area of the display surface of the flexible screen 23 is the same as the area of the display opening 101, so as to improve the viewing experience.

[0054] The driving structure 13 is connected to the rear shell plate 1112, and is capable of driving the sliding body 121 to reciprocally slide relative to the shell body 111.

[0055] In some embodiments, please refer to Figure 6 and Figure 7The driving structure 13 comprises a telescopic driving member 131 and a screw rod 132 connected to the telescopic driving member 131, and the second shell 12 is threadedly connected to the screw rod 132 through a screw member 24. The telescopic driving member 131 is connected to the first shell 11 and can drive the screw rod 132 to rotate, so as to drive the second shell 12 to move relative to the first shell 11 through the screw member 24, and the second end 10b moves close to or away from the first end 10a. The telescopic driving member 131 can be an electric motor, the driving shaft of the electric motor is in transmission connection with the screw rod 132, and the screw rod 132 extends along the thickness direction of the first shell 11. The telescopic driving member 131 is connected to the rear shell plate 1112, the screw member 24 is connected to the sliding body 121, and the telescopic driving member 131 drives the sliding body 121 to slide relative to the shell body 111 by driving the screw rod 132 to rotate, so as to drive the second shell 12 to move between the first position and the second position.

[0056] The first shell 11 is provided with a circuit board 30, and the circuit board 30 is electrically connected to the flexible screen 23 and the telescopic driving member 131 through wiring. In this way, when the driving structure 13 drives the second shell 12 to move, the wiring is always located in the first shell 11 and does not change position, thereby improving the electrical connection reliability between the circuit board 30 and the flexible screen 23 and the telescopic driving member 131.

[0057] Optionally, the driving structure 13 further comprises a driving shell 133, and the telescopic driving member 131 and the screw rod 132 are located in the driving shell 133. The driving shell 133 is connected to the rear shell plate 1112, and the driving shell 133 can protect the telescopic driving member 131 and the screw rod 132.

[0058] In other embodiments, the driving structure 13 can also be a pneumatic cylinder, a scissor-shaped driving member, a gear structure, a track structure, etc., as long as it can realize the movement of the second shell 12 relative to the first shell 11, and the present application is not limited in this regard.

[0059] In some embodiments, referring to Figure 6 and Figure 7 The winding structure 21 comprises first and second winding shafts 211 and 212 which are spaced apart from each other. The first and second winding shafts 211 and 212 are both rotationally connected to the second shell 12, the first winding shaft 211 is close to the first end 10a, and the second winding shaft 212 is close to the second end 10b, i.e., the first winding shaft 211 is located on the side of the second winding shaft 212 close to the first end 10a, and the winding belt 22 is wound around the first and second winding shafts 211 and 212 in sequence. The axis of the second winding shaft 212 avoids the display opening 101 in the thickness direction of the second shell 12, so that the flexible screen 23 covers the display opening 101. In this way, the winding belt 22 can be tensioned through the first and second winding shafts 211 and 212, and the flexible screen 23 is prevented from being damaged or scratched due to laminated winding.

[0060] Optionally, referring to Figure 6 and Figure 7 Both ends of the winding belt 22 are connected to the first housing 11, wherein the first winding shaft 211 is located on the side of the support plate 112 facing away from the first display port 1011, one end of the winding belt 22 is connected to the first end 10a of the housing body 111, and the other end is connected to the side of the support plate 112 facing away from the first display port 1011. When the driving structure 13 drives the second housing 12 to move from the first position to the second position, the second winding shaft 212 pulls the winding belt 22 to release, the first winding shaft 211 moves from the position close to the first end 10a of the first housing 11 to the position away from the first end 10a, until it approaches the connected end of the winding belt 22 on the support plate 112, and the flexible screen 23 gradually unfolds from the folded state with the release of the winding belt 22.
