[0037] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] like Figure 1 As shown, an embodiment of the present invention provides a vehicle, comprising a roof 1 and a display device. Figure 1 Only the connection structure between the ceiling 1 and the display device is shown.

[0039] like Figure 1 and Figure 3 As shown, the display screen device includes a display screen 2, a display screen frame 3, and a gap cover assembly. The display screen frame 3 is fixed to the ceiling 1. The display screen 2 has a display connection side 21 that is rotatably connected to the display screen frame 3, allowing the display screen 2 to rotate back and forth between a closed position and an open position. In the closed position, the display screen 2 is accommodated in the display screen frame 3. In the open position, the display screen 2 is flipped open.

[0040] like Figure 1 and Figure 2As shown, the gap cover assembly includes a gap cover 4, a roller 5 and an elastic reset part. The gap cover 4 is installed between the display screen connection side 21 of the display screen 2 and the display screen frame 3. The gap cover 4 has a cover connecting side 41 and a cover rotating side 42 that are relatively arranged. The cover connecting side 41 is rotatably connected to the display screen frame 3.

[0041] The roller 5 is rotatably mounted on the cover plate rotation side 42 and abuts against the back of the display screen connection side 21 under the elastic force of the elastic reset member. Figure 1 The surface indicated by A is the back surface of the display screen 2 .

[0042] like Figure 3 and Figure 4 As shown, the roller 5 is used to rotate and push the gap cover 4 to overcome the elastic force of the elastic reset member when the display screen 2 is flipped, so that the gap cover 4 is close to the back of the display screen 2, so that the gap cover 4 can block the gap between the back of the display screen connection side 21 and the display screen frame 3 during the flipping process of the display screen 2.

[0043] Specifically, if Figure 1 and Figure 2 As shown, when the display screen 2 is in the closed position, the display screen 2 is accommodated in the display screen frame 3, the gap cover 4 installed between the display screen connection side 21 and the display screen frame 3 blocks the gap between the display screen connection side 21 and the display screen frame 3, and the roller 5 abuts the display screen connection side 21.

[0044] like Figure 3 and Figure 4 As shown, when the display screen 2 turns to the open screen position, the flipped display screen 2 pushes the gap cover 4 through the roller 5 to overcome the elastic force of the elastic reset part and rotate, so that the gap cover 4 rotates with the display screen 2. The gap cover 4 can always be attached to the back of the display screen 2 during the flipping process of the display screen 2, so that the gap cover 4 can always cover the gap between the display screen connection side 21 and the display screen frame 3 during the flipping process of the display screen 2, thereby improving the appearance of the product and avoiding the risk of pinching hands.

[0045] Moreover, during the flipping process of the display screen 2, the position where the back surface of the display screen connection side 21 abuts against the roller 5 is constantly changing, that is, the display screen 2 and the roller 5 have a relative sliding motion along the plane where the back surface of the display screen 2 is located. Since the roller 5 is rotatably mounted on the slit cover plate 4, the roller 5 can roll when the display screen 2 slides relative to the roller 5, so that the friction between the roller 5 and the back surface of the display screen 2 is rolling friction. Compared with the sliding friction between the sliding sheet and the display screen 2 in the prior art, the rolling friction is smaller, thereby reducing the wear and scratches on the back surface of the display screen 2 during the flipping process.

[0046] In the vehicle of the present invention, the gap cover 4 is installed between the display screen connection side 21 of the display screen 2 and the display screen frame 3. The cover plate connection side 41 of the gap cover 4 is rotatably connected to the display screen frame 3. When the display screen 2 is flipped, the roller 5 rotatably installed on the cover plate rotation side 42 abuts the back of the display screen connection side 21. Therefore, the display screen 2 can push the gap cover 4 to rotate via the roller 5, so that the gap between the back of the display screen 2 and the display screen frame 3 is always blocked during the flipping process of the display screen 2. The roller 5 can rotate relative to the back of the display screen 2 during the flipping process of the display screen 2, so that the friction between the roller 5 and the back of the display screen 2 is rolling friction. Compared with the sliding friction between the sliding sheet and the display screen 2 in the prior art, the rolling friction is smaller, which can reduce wear and scratches on the back of the display screen 2 during the flipping process of the display screen 2, and is beneficial for protecting the appearance of the display screen 2.

[0047] In one embodiment, if Figure 1 and Figure 2 As shown, in the closed screen position, the surface of the side of the seam cover 4 facing the interior of the vehicle is flush with the back of the display screen 2, avoiding a height difference between the seam cover 4 and the back of the display screen 2, thereby improving the aesthetics and safety of the product.

[0048] In one embodiment, if Figure 7 and Figure 8 As shown, the roller 5 includes a roller body and an elastic layer 51. The roller body is a rigid part. The elastic layer 51 is arranged on the periphery of the roller body. The roller body is rotatably installed on the seam cover 4, so that the elastic layer 51 is in flexible contact with the back of the display screen 2. The friction between the elastic layer 51 and the display screen 2 is small, so as to further reduce the friction damage between the roller 5 and the back of the display screen 2 during the flipping of the display screen 2, and at the same time, avoid noise during the flipping of the display screen 2.

[0049] In one embodiment, the elastic layer 51 is made of elastic rubber, synthetic rubber, or thermoplastic polyurethane elastomer.

[0050] In one embodiment, if Figure 7 and Figure 8 As shown, the roller body includes a roller 52 and a roller shaft 53. An elastic layer 51 wraps around the outer circumference of the roller 52. The roller shaft 53 penetrates the roller 52 and is rotatably mounted on the rotating side 42 of the cover plate, so that the roller 52 and the roller shaft 53 are arranged separately. During the flipping process of the display screen 2, the roller shaft 53 can remain stationary on the slit cover plate 4 while the roller 52 rotates relative to the roller shaft 53. The display screen 2 transmits a driving force to the slit cover plate 4 via the path of roller 52-roller-slit cover plate 4, thereby reducing friction between the roller shaft 53 and the slit cover plate 4, reducing wear on the roller shaft 53, and increasing its service life.

[0051] In one embodiment, if Figure 5 As shown, the rotation axis of the slit cover 4 is parallel to the rotation axis of the roller 5, and the rotation axis of the roller 5 is parallel to the rotation axis of the display screen 2, so that during the flipping process of the display screen 2, the roller 5 can rotate stably with the display screen 2, and the roller 5 can push the slit cover 4 to rotate stably, so as to improve the stability of the slit cover 4 when rotating with the display screen 2.

[0052] In one embodiment, if Figure 2 As shown, the slit cover plate 4 has a first surface 43 and a second surface 44 disposed opposite each other. The first surface 43 is exposed to the interior of the vehicle. The outer circumference of the roller 5 at least partially protrudes from the second surface 44 in a direction away from the first surface 43 and abuts the display screen 2. Compared to the situation where the highest point of the outer circumference of the roller 5 is exactly flush with the second surface 44, this design can improve the reliability of the roller 5 abutting the back of the display screen 2 during the flipping process of the display screen 2.

[0053] In one embodiment, if Figure 3 and Figure 4 As shown, the roller 5 is rotatably mounted on the side of the second surface 44 facing away from the first surface 43. When the display screen 2 is flipped open, the roller 5 is hidden between the gap cover 4 and the display screen 2, improving the aesthetics of the product. In addition, the side of the second surface 44 facing away from the first surface 43 has a larger space, which is convenient for mounting the roller 5.

[0054] In one embodiment, if Figure 3 As shown, the outer peripheral surface of the roller 5 is in contact with the second surface 44. When the display screen 2 is flipped, the roller 5 can transmit the driving force to the slit cover 4 through the position where it contacts the second surface 44, and the slit cover 4 can also support the roller 5 through the second surface 44 to improve the stability of the roller 5.

[0055] In one embodiment, if Figure 6 As shown, a fixing platform 46 is provided on the second surface 44 of the gap cover 4. The fixing platform 46 is located on the cover rotating side 42 of the gap cover 4. A notch is provided on the fixing platform 46, and the roller 5 is installed in the notch.

[0056] Specifically, shaft mounting holes are provided on both sides of the fixing platform 46 and the notch, and both ends of the roller shaft 53 are respectively inserted into the shaft mounting holes.

[0057] In one embodiment, if Figure 7 As shown, a plurality of rollers 5 are provided, and the plurality of rollers 5 are spaced apart along the direction of the rotation axis thereof, so that the display screen 2 can push the slit cover plate 4 to rotate through the plurality of rollers 5, so as to increase the force points of the slit cover plate 4, make the force on the slit cover plate 4 more balanced, and improve the stability of the slit cover plate 4 when rotating.

[0058] In one embodiment, three rollers 5 are provided, and the three rollers 5 are evenly spaced apart along the direction of the rotation axis.

[0059] In one embodiment, the fixing platform 46 extends along the rotation axis of the roller 5 , and three intervally distributed notches are provided on the fixing platform 46 .

[0060] In one embodiment, as shown in 7 , a cover plate rear cover 7 is further included, which is stacked on the side of the gap cover 4 facing away from the interior of the vehicle and fixed on the gap cover 4 , and a clearance opening for avoiding the roller 5 is provided on the cover plate rear cover 7 .

[0061] In one embodiment, if Figure 4 、 Figure 5 and Figure 6 As shown, the elastic reset member is a tension spring 6, which includes a first leg and a second leg. The first leg is connected to the cover connecting side 41, and the second leg is fixed to the display frame 3. The tension spring 6 pulls the cover connecting side 41 away from the interior of the vehicle.

[0062] Since the tension spring 6 pulls the cover plate connection side 41 away from the interior of the vehicle, the tension spring 6 can prevent the gap cover plate 4 from rotating toward the interior of the vehicle when the display screen 2 is in the closed position, so that the gap cover plate 4 remains in the closed position and covers the gap between the display screen 2 and the display screen frame 3. When the display screen 2 rotates toward the open position, the display screen 2 pushes the gap cover plate 4 via the roller 5, so that the gap cover plate 4 overcomes the pulling force of the tension spring 6 and rotates. When the display screen 2 rotates toward the closed position, the pushing force of the display screen 2 on the roller 5 is gradually withdrawn. Since the tension spring 6 pulls the cover plate connection side 41 away from the interior of the vehicle, the gap cover plate 4 can be rotated toward the outside of the vehicle under the pull of the tension spring 6, so that the roller 5 abuts the display screen 2 in the closed position.

[0063] Compared with the prior art, in which the slit cover plate assembly 4 is reset by a torsion spring, torsion springs need to be provided on both sides of the rotating shaft of the slit cover plate 4, and a rotating shaft fixing seat needs to be provided on the display screen frame 3. The rotating shaft is rotatably installed on the rotating shaft fixing seat, one end of the torsion spring is fixed on the rotating shaft fixing seat, and the other end is fixed on the rotating shaft, resulting in the slit cover plate assembly having more structural parts and a complex structure. The slit cover plate assembly in the utility model only uses a tension spring 6, which has a simple structure, low cost, and is easy to assemble.

[0064] In one embodiment, a fixing frame 8 is provided on the side of the cover connecting side 41 facing away from the roller 5, the fixing frame is fixed on the display screen frame 3, the tension spring 6 is accommodated in the fixing frame 8, and the second support leg is connected to the frame edge of the fixing frame 8 opposite to the cover connecting side 41.

[0065] In one embodiment, a first hanging hole is provided on the cover connecting side 41, and a second hanging hole is provided on the edge of the fixed frame 8. The first hanging hole and the second hanging hole are arranged opposite each other along the tension direction of the tension spring 6. The first leg is hung in the first hanging hole, and the second leg is hung in the second hanging hole. The tension spring 6 is easily installed by installing it through the first and second hanging holes.

[0066] In one embodiment, if Figure 2 As shown, the gap cover plate 4 is provided with a vertical edge 47 extending along its rotation axis direction. The vertical edge 47 is located at the edge of the cover plate connecting side 41 and is perpendicular to the gap cover plate 4. The first hanging hole is provided on the vertical edge 47.

[0067] In one embodiment, the display screen 2 is a square screen, the slit cover plate 4 is a square plate, the cover plate rotating side 42 and the cover plate connecting side 41 are arranged opposite to each other along the width direction of the slit cover plate 4, the display screen connecting side 21 is located on one side in the width direction of the display screen 2, and the length of the slit cover plate 4 is the same as the length of the display screen 2.

[0068] In one embodiment, if Figure 5 As shown, the tension direction of the tension spring 6 is perpendicular to the rotation axis of the cover plate 4. The tension spring 6 is provided with a first leg connected to the middle position of the cover plate connection side 41. The tension force exerted by the tension spring 6 on the cover plate 4 is perpendicular to the rotation axis of the cover plate 4 and is located in the middle position of the cover plate 4 along its rotation axis, so that the cover plate 4 is subjected to a balanced force and prevents the cover plate 4 from swinging when rotating.

[0069] In one embodiment, if Figure 5 As shown, two cover plate shafts 45 are also included. Cover plate shaft holes 45 are provided at both ends of the cover plate rotating side 42 along its rotation axis. Frame shaft holes are provided on the two frame edges of the display screen frame 3 that are relatively arranged along the rotation axis of the slit cover plate 4. The two ends of the cover plate shaft 45 are respectively inserted into the cover plate shaft holes 45 and the frame shaft holes.

[0070] In other embodiments, a plurality of tension springs 6 are provided, and the plurality of tension springs 6 are spaced apart along the direction of the rotation axis of the slot cover plate 4. The number of tension springs 6 can be adjusted according to actual needs, for example, two, three or more.

[0071] In other embodiments, the roller 5 may only include a roller body.

[0072] In other embodiments, the roller 5 and the roller shaft 53 may be integrally formed.

[0073] In other embodiments, the rotation axis of the gap cover 4 may have an angle with the rotation axis of the roller 5, such as 30°, 60°, etc., and the rotation axis of the roller 5 may have an angle with the rotation axis of the display screen 2, such as 30°, 60°, etc., to ensure that the roller 5 can rotate circumferentially during the flipping of the display screen 2.

[0074] In other embodiments, the roller 5 can be rotated to install the edge of the rotating side 42 of the cover and be located between the first surface 43 and the second surface 44. The highest point of the outer peripheral surface of the roller 5 can be flush with the second surface 44. In order to avoid interference between the second surface 44 and the back of the display screen 2 during the flipping process of the display screen 2, the edge of the second surface 44 can be designed to be inclined so that the roller 5 can always abut the back of the display screen 2.

[0075] In other embodiments, only one roller 5 may be provided, which is rotatably mounted in the middle of the cover plate rotation side 42. Of course, the number of rollers 5 may be adjusted according to actual application requirements, such as two, four, or more.

[0076] In other embodiments, the elastic reset member can be a torsion spring. The display screen frame 3 is provided with a fixed seat arranged relatively along the rotation axis direction of the slit cover 4. The two ends of the roller shaft 53 are respectively rotatably mounted on the two fixed seats. The roller shaft 53 is provided with a torsion spring, one end of the torsion spring is fixed on the fixed seat, and the other end is fixed on the roller shaft 53.

[0077] In addition, an embodiment of the present invention provides a display screen device, the structure of which is the same as that of the display screen device in any of the above embodiments, and will not be described in detail here.

[0078] In addition, an embodiment of the present invention provides a gap cover assembly, the structure of which is the same as that of the gap cover assembly in any of the above embodiments, and will not be repeated here.
