These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0079] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0080] Referring to Figures 1 and 2 , Figure 1 is a schematic diagram of the external structure of a display device provided in an embodiment of the present application, and Figure 2 is a schematic diagram of a partial structure of a display device provided in an embodiment of the present application. The display device may include: a first housing 100, a second housing 200, a scroll 300, a force-bearing member 400, and a flexible display panel 500.

[0081] The first housing 100 in the display device may include a fixing member 101 and a sliding member 102 slidably connected to the fixing member 101 .

[0082] The second housing 200 in the display device may be fixedly connected to a side of the fixing member 101 facing away from the sliding member 102 , and an angle between the first housing 100 and the second housing 200 may be less than 180 degrees.

[0083] The scroll 300 in the display device may include: a plurality of sub-scrolls 301 arranged in an array, and each sub-scroll 301 may be rotatably connected to at least one of the first shell 100 and the second shell 200 .

[0084] The force-bearing member 400 in the display device may be located in the second housing 200 and may be movably connected to the second housing 200. In order to clearly see the position of the force-bearing member, only a partial structure of the second housing 200 is shown in FIG2 .

[0085] Please refer to Figures 3 and 4. Figure 3 is an exploded schematic diagram of a partial structure of a display device provided in an embodiment of the present application, and Figure 4 is an exploded schematic diagram of a partial structure of another display device provided in an embodiment of the present application. The flexible display panel 500 in the display device may include: a rollable display portion 501 wound around multiple sub-rollers 301, and a first planar display portion 502 and a second planar display portion 503 located on either side of the rollable display portion 501. The first planar display portion 502 in the flexible display panel 500 can be connected to the sliding member 102, and the second planar display portion 503 can be connected to the force-bearing member 400 within the second housing 200.

[0086] In the embodiment of the present application, a scroll 300 is provided between the first housing 100 and the second housing 200, and after the first planar display portion 502 of the flexible display panel 500 is connected to the sliding member 102 and the second planar display portion 503 is connected to the force-bearing member 400, the rolled display portion 501 in the flexible display panel 500 can be wound on the scroll 300. The scroll 300 can be rotatably connected to the housing, thereby enabling indirect rotation of the rolled display portion 501 in the flexible display panel 500 when passing through the axis area, thereby reducing the friction of the rolled display portion 501 in the flexible display panel 500, thereby reducing the frictional resistance when the display device switches between the expanded state and the retracted state. In addition, by setting the scroll 300 as a plurality of sub-scrolls 301 arranged in an array, the length of a single sub-scroll 301 is shorter and easier to process and the axial accuracy of the sub-scroll 301 can be guaranteed. After the plurality of sub-scrolls 301 are installed on the shell, the coaxiality of the formed scroll can be ensured to be better, so that the curled display part 501 in the flexible display panel 500 will not produce the undesirable phenomenon of warping or collapse when passing through the axis area, thereby ensuring that the display effect of the flexible display panel 500 in the display device is better.

[0087] For example, the flexible display panel 500 in the display device can flexibly adjust the size of the display surface of the flexible display panel during the process of extension and contraction, so that the flexible display panel 500 can be adapted to different usage scenarios. For example, when the display device is used on a means of transportation (e.g., a vehicle), the size of the flexible display panel extended from the display device can be flexibly adjusted, so that the flexible display panel is adapted to different usage scenarios of the vehicle. In this way, the user's entertainment and safety requirements can be met, and the installation space requirements for the vehicle are low. In particular, for large-sized flexible display screens, the size of the flexible display screen can be adjusted according to different usage scenarios in a vehicle environment. For example, when the vehicle is driving, part of the flexible display screen is accommodated in the internal space of the display device, reducing the display area of ​​the flexible display screen, and using a smaller display screen to provide driving information of the vehicle, providing a good driving field of view. When the vehicle is in an entertainment state, a larger part or all of the flexible display screen extends out of the internal space of the display device, increasing the display area and meeting the user's entertainment needs.

[0088] In summary, embodiments of the present application provide a display device that may include: a first housing, a second housing, a scroll, a force-bearing member, and a flexible display panel. By disposing the scroll between the first and second housings, and after the first planar display portion of the flexible display panel is connected to the sliding member and the second planar display portion is connected to the force-bearing member, the rolled display portion of the flexible display panel can be wound around the scroll. The scroll can be rotatably connected to the housing, enabling indirect rotation of the rolled display portion of the flexible display panel as it passes through an axial region, thereby reducing friction in the rolled display portion of the flexible display panel and thereby lowering frictional resistance when the display device switches between an expanded state and a retracted state. Furthermore, by configuring the scroll as a plurality of sub-scrolls arranged in an array, the length of each sub-scroll is relatively short, making it easier to manufacture and ensuring axial precision of the sub-scrolls. After the plurality of sub-scrolls are mounted on the housing, the resulting scroll can maintain good coaxiality, preventing the rolled display portion of the flexible display panel from warping or collapsing when passing through the axial region, thereby ensuring a good display effect of the flexible display panel in the display device.

[0089] Alternatively, please refer to Figure 5, which is a schematic diagram illustrating the connection between a sub-reel and a housing according to an embodiment of the present application. Each sub-reel 301 in the reel 300 may include a rotating shaft 301a and a reel 301b sleeved on the rotating shaft 301a. The two ends of the rotating shaft 301a may be fixedly connected to the fixing member 101, and the reel 301b may be rotatably connected to the rotating shaft 301a; alternatively, the two ends of the rotating shaft 301a may be rotatably connected to the fixing member 101, and the reel 301b may be fixedly connected to the rotating shaft 301a.

[0090] In an embodiment of the present application, as shown in FIG5 , the display device may further include: a plurality of first support bases 600 and a plurality of second support bases 700, each of which may be fixedly connected to the fixing member 101. The plurality of first support bases 600 and the plurality of second support bases 700 each correspond one-to-one to the plurality of sub-scrolls 301, and each sub-scroll 301 may be located between the corresponding first support base 600 and the second support base 700, and the first end of the rotating shaft 301a in the sub-scroll 301 may be connected to the corresponding first support base 600, and the second end of the rotating shaft 301a in the sub-scroll 301 may be connected to the corresponding second support base 700. In this case, each sub-scroll 301 corresponds to a set of first support bases 600 and a second support set 700. After the ends of the rotating shaft 301a in the sub-scroll 301 are respectively connected to the first support base 600 and the second support base 700, the first support base 600 and the second support base 700 are fixed to the fixing member 101. In this way, after the sub-reel 301 ensures the installation accuracy with the first support seat 600 and the second support seat 700 through the rotating shaft 301a, it is only necessary to ensure the installation accuracy of the first support seat 600 and the second support seat 700 with the fixing member 101 to ensure the installation accuracy of the reel 300 with the housing. It should be noted that by adjusting the installation accuracy of the two ends of the rotating shaft 301a in the sub-reel 301 with the two support seats, and the installation accuracy of the two support seats with the fixing member 101, it is possible to compensate for the deviations formed during the processing of a single long rotating shaft.

[0091] For example, as shown in FIG5 , the plurality of sub-reels 301 may include: two first sub-reels A1 located at the outermost ends, and at least one second sub-reel A2 located between the two first sub-reels A1. The fixing member 101 has a plurality of first extensions 101a and two second extensions 101b. The first extensions 101a may be located between adjacent first sub-reels A1 and second sub-reels A2, and / or between adjacent second sub-reels A2, and between adjacent first sub-reels A1 and second sub-reels A2. The second extensions 101b may be located on the side of the first sub-reel A1 facing away from the second sub-reel A2. The first support seat 600 corresponding to the first sub-scroll A1 can be fixedly connected to the second extension part 101b, and the second support seat 700 corresponding to the first sub-scroll A1 can be fixedly connected to the first extension part 101a; the first support seat 600 corresponding to the second sub-scroll A2 can be fixedly connected to the first extension part 101a, and the second support seat 700 corresponding to the second sub-scroll A2 can be fixedly connected to the first extension part 101a.

[0092] It should be noted that the two ends of the rotating shaft 301a in the sub-scroll 301 can be rotatably connected to the corresponding first support seat 600 and second support seat 700, and the reel 301b can be fixedly connected to the rotating shaft 301a. In the present application, as shown in Figure 5, the display device may also include: two first bearings A3 corresponding to a set of first support seats 600 and second support seats 700, the outer ring of one first bearing A3 can be fixedly connected to the first support seat 600, and the inner ring of one first bearing A3 can be sleeved with one end of the rotating shaft 301a; the outer ring of the other first bearing A3 can be fixedly connected to the second support seat 700, and the inner ring of the other first bearing A3 can be sleeved with the other end of the rotating shaft 301a. In this case, the two ends of the rotating shaft 301a are respectively connected to the first support seat 600 and the second support seat 700 through the first bearing A3, which can effectively ensure the installation accuracy of the rotating shaft 301a in each sub-scroll 301 and the two support seats, and can ensure that the rotating shaft 301a in the sub-scroll 301 slides smoothly relative to the two support seats.

[0093] Optionally, as shown in FIG5 , the first support base 600 and the second support base 700 located between two adjacent sub-reels 301 may be fixedly connected. That is, in two adjacent sub-reels 301, the second support base 700 connected to one end of one sub-reel 301 and the first support base 600 connected to one end of the other sub-reel 301 may be an integrated structure.

[0094] In the embodiments of the present application, there are multiple possible implementations of a tensioning system for tensioning a flexible display panel during switching between an expanded state and a contracted state in a display device. The following uses two optional implementations as examples for schematic illustration:

[0095] Regarding a first alternative implementation, please refer to Figures 6 and 7. Figure 6 is a schematic diagram of a display device in a retracted state according to an embodiment of the present application, and Figure 7 is a schematic diagram of a display device in an extended state according to an embodiment of the present application. The display device may further include a first pulley 800, a second pulley 900, and a tensioning cord 1000. The first pulley 800 may be connected to a side of the fixed member 101 facing away from the reel 300, and the second pulley 900 may be connected to a side of the second housing 200 facing away from the reel 300. A first end a1 of the tensioning cord 1000 may be fixedly connected to a side of the sliding member 102 proximal to the reel 300, and the tensioning cord 1000 is sequentially wound around the first pulley 800, the reel 300, and the second pulley 900. A second end a2 of the tensioning cord 1000 may be fixedly connected to a side of the force-bearing member 400 facing away from the reel 300. During the sliding of the sliding member 102 relative to the fixed member 101, the first end a1 of the tensioning cord 1000 can always be located on the side of the first pulley 800 facing the reel 300. For example, when the force-bearing member 400 is subjected to an external force and moves along the f1 axis, the force-bearing member 400 can drive the second end a2 of the tensioning cord 1000 to move in a direction closer to the reel 300. The tensioning cord 1000, wound around the first and second pulleys 800 and 900, can move under the action of the pulleys, allowing the first end a1 of the tensioning cord 1000 to drive the sliding member 102 to move along the f2 axis relative to the fixed member 101, thereby driving the entire flexible display panel 500 to unfold via the first planar display portion 502. In this way, the coordination of the tensioning cord 1000 and the two pulleys can simultaneously flatten the flexible display panel 500 while providing driving force for the movement of the sliding member 102. This can reduce the thrust of the drive components in the display device, thereby lowering manufacturing costs. Furthermore, when the force-bearing member 400 is subjected to an external force and moves along the f3 axis, the force-bearing member 400 can apply a force to the second planar display portion 503 of the flexible display panel 500, thereby driving the second end a2 of the tensioning cord 1000 to move away from the reel 300. Furthermore, the tensioning cord 1000, wound around the first pulley 800 and the second pulley 900, can move under the action of the pulleys, allowing the first end a1 of the tensioning cord 1000 to drive the sliding member 102 to move along the f4 axis relative to the fixed member 101, thereby achieving contraction of the display device. It should be noted that, after the first pulley 800 is connected to the fixed member 101, it can function as a fixed pulley to change the direction of the force acting on the tensioning cord 1000, and after the second pulley 900 is connected to the second housing 200, it can function as a fixed pulley to change the direction of the force acting on the tensioning cord.

[0096] Alternatively, please refer to Figures 7 and 8, which are partial structural diagrams of another display device provided in an embodiment of the present application. The display device may further include: a first tensioning assembly (not shown) and / or a second tensioning assembly 1100. The first tensioning assembly may be connected to the first pulley 800 and the fixing member 101, respectively, and the first tensioning assembly may be configured to apply a force to the first pulley 800 in a direction away from the reel 300. The second tensioning assembly 1100 may be connected to the second pulley 900 and the second housing 200, respectively, and the second tensioning assembly 1100 may be configured to apply a force to the second pulley 900 in a direction away from the reel 300. It should be noted that the manner in which the first tensioning assembly applies tension to the tensioning rope 1000 via the first pulley 800 is similar to the manner in which the second tensioning assembly 1100 applies tension to the tensioning rope 1000 via the second pulley 900. The following embodiments are schematically described using the second tensioning assembly 1100 as an example. In this way, by applying a force in a direction away from the reel 300 to the second pulley 900 through the second tensioning assembly 1100, a certain pre-tensioning force can be provided for the tensioning rope 1000, further ensuring that the flexible display panel 500 in the display device bulges very little when switching between the expanded state and the contracted state.

[0097] In the present application, the first tensioning assembly may include: a first elastic element, a first connecting block, and a first fastener, wherein one end of the first fastener may be fixedly connected to a side of the fixing member facing away from the reel, the extension direction of the first fastener may intersect with the reel, and the first connecting block and the first elastic element may both be sleeved on the first fastener. The first elastic element may be located between the fixing member and the first connecting block, wherein both ends of the first elastic element may respectively abut against the fixing member and the first connecting block, and the end of the first fastener facing away from the fixing member may abut against a side of the first connecting block facing away from the fixing member, and the first pulley may be rotatably connected to the first connecting block.

[0098] And / or, as shown in FIG8 , the second tensioning assembly 1100 may include: a second elastic element 1101, a second connecting block 1102, and a second fastener 1103. One end of the second fastener 1103 may be fixedly connected to a side of the second housing 200 facing away from the reel 300, and the extension direction of the second fastener 1103 may intersect with the extension direction of the reel 300. The second connecting block 1102 and the second elastic element 1101 may both be sleeved onto the second fastener 1103. The second elastic element 1101 may be located between the second housing 200 and the second connecting block 1102. Both ends of the second elastic element 1101 may abut against the second housing 200 and the second connecting block 1102, respectively. The end of the second fastener 1103 facing away from the second housing 200 may abut against a side of the second connecting block 1102 facing away from the second housing 200. The second pulley 900 may be rotatably connected to the second connecting block 1102. In this case, by making the end of the second fastener 1103 facing away from the second housing 200 abut against the side of the second connecting block 1102 facing away from the second housing 200, the second elastic element 1101 located between the second housing 200 and the second connecting block 1102 can apply a force to the second connecting block 1102 in a direction away from the second housing 200, thereby directly applying a force in a direction away from the second housing 200 to the tension rope wrapped around the second pulley 900 through the second pulley 900, so that the tension rope 1000 is always pre-tensioned. For example, the first fastener and the second fastener 1103 can both be fastening screws, and the first elastic element and the second elastic element 1101 can both be compression springs.

[0099] In an embodiment of the present application, a first connecting block in a display device may have a first mounting cavity and a first opening communicating with the first mounting cavity. A first pulley may be located within the first mounting cavity and rotatably connected to the first connecting block. The first opening on the first connecting block may be oriented toward the reel, and the first opening may be used for passing a tensioning cord in and out. For example, the first end of the tensioning cord may pass through the first opening into the first mounting cavity, around the first pulley, and then out through the first opening to connect to the sliding member.

[0100] Alternatively, as shown in FIG8 , the second connecting block 1102 may have a second mounting cavity b1 and a second opening b2 communicating with the second mounting cavity b1. The second pulley 900 may be positioned within the second mounting cavity b1 of the second connecting block 1102 and rotatably connected to the second connecting block 1102. The second opening b2 on the second connecting block 1102 may be oriented toward the reel 300 and may be used to allow the tensioning cord 1000 to pass through and out of the second opening b2. For example, the second end of the tensioning cord 1000 may pass through the second opening b2 into the second mounting cavity b1, pass around the second pulley 900, and then exit through the second opening b2 to connect to the force-bearing member 400. In this case, by providing the second mounting cavity b1 and the second opening b2 communicating with the second mounting cavity b1 in the second connecting block 1102, the second pulley 900 is positioned within the second mounting cavity b1 and rotatably connected to the second connecting block 1102. This improves the integration of the display device and effectively reduces the overall size of the display device.

[0101] Optionally, please refer to Figure 9, which is a partial structural diagram of another display device provided in an embodiment of the present application. The first pulley 800 in the display device may include: a first pulley body 801 and a first pin 802, one end of the first pin 802 may be connected to the fixing member 101, the first pulley body 801 may be sleeved on the first pin 802 and may be rotatably connected to the first pin 802. The second pulley 900 in the display device may include: a second pulley body 901 and a second pin 902, one end of the second pin 902 may be connected to the second housing 200, the second pulley body 901 may be sleeved on the second pin 902 and may be rotatably connected to the second pin 902. The axial direction of the first pin 802 may be perpendicular to the plane of the first housing 100, and / or the axial direction of the second pin 902 may be perpendicular to the plane of the second housing 200. In this case, the first pulley body 801 is connected to the fixing member 101 via the first pin 802, and the second pulley body 901 is connected to the second housing 200 via the second pin 902. The axial direction of the first pin 802 is perpendicular to the plane of the first housing 100, and the axial direction of the second pin 902 is perpendicular to the plane of the second housing 200. That is, the first pulley body 801 and the second pulley body 901 are both installed flat, so that the overall thickness of the display device in a direction perpendicular to the plane of the first housing 100 and in a direction perpendicular to the plane of the second housing 200 are both small. It should be noted that in other possible implementations, the axial direction of the first pin 802 can be parallel to the plane of the first housing 100, and both ends of the first pin 802 can be connected to the fixing member 101; the axial direction of the second pin 902 can also be parallel to the plane of the second housing, and both ends of the second pin 902 can be connected to the second housing 200.

[0102] In an embodiment of the present application, as shown in Figure 9, the display device may further include: a first drive component 1200, which may be fixed in the second shell 200, and the first drive component 1200 may be connected to the force-bearing member 400. Among them, the first drive component 1200 may be configured to: drive the force-bearing member 400 to move in the second shell 200 in a direction perpendicular to the scroll 300. In the present application, the display device also includes: a control component (not shown in the figure) electrically connected to the first drive component, and the control component can control the first drive component to perform normal operation after receiving the drive instruction. In this case, by providing the first drive component 1200 in the display device, the force-bearing member 400 can be driven to move by the first drive component 1200, thereby driving the flexible display panel 500 in the display device to expand and contract, thereby improving the degree of automation of the display device.

[0103] For example, please refer to Figure 10, which is a partial structural diagram of another display device provided in an embodiment of the present application. The first drive assembly 1200 may include: a first drive motor 1201, a first transmission shaft 1202 and a first transmission member 1203. The first drive motor 1201 can be fixedly connected to the second shell 200, and the first drive motor 1201 can be connected to one end of the first transmission shaft 1202. The first transmission member 1203 can be sleeved on the first transmission shaft 1202, the first transmission shaft 1202 can be arranged perpendicular to the scroll 300, and the first transmission member 1203 can be connected to the force-bearing member 400. Among them, the first drive motor 1201 can be configured to: when driving the first transmission shaft 1202 to rotate, the force-bearing member 400 is driven to move along the length direction of the first transmission shaft 1202 through the first transmission member 1203. In this case, when the first drive motor 1201 is operating, it can drive the first transmission shaft 1202 to rotate. During the rotation of the first transmission shaft 1202, it can drive the first transmission member 1203 to move along the first transmission shaft 1202. The first transmission member 1203 can then drive the force-bearing member 400 to move along the length direction of the first transmission shaft 1202. After the flexible display panel 500 in the display device moves to the designated position, the first drive motor 1201 stops operating.

[0104] In a second optional implementation, please refer to Figure 11, which is a schematic diagram of the effect of a display device provided in an embodiment of the present application switching between an expanded state and a retracted state. The display device also includes: a second drive assembly 1300 located in the first shell 100, and an elastic recovery assembly 1400 fixed in the second shell 200. The second drive assembly 1300 can be connected to the sliding member 102 in the first shell 100, and a portion of the second drive assembly 1300 can extend into the second shell 200 and be fixedly connected to the second shell 200, and the elastic recovery assembly 1400 can be fastened to the side of the force-bearing member 400 away from the scroll 300. The second drive assembly 1300 can be configured to: drive the sliding member 102 to move relative to the fixing member 102 in the first shell 100 in a direction perpendicular to the scroll 300. In this case, by connecting the second driving assembly 1300 to the sliding member 102, the second driving assembly 1300 can drive the sliding member 102 to move relative to the fixed member 101, thereby driving the entire flexible display panel 500 to expand or contract via the first planar display portion 502. In addition, the elastic recovery assembly 1400 fixed within the second housing 200 can be connected to the force-bearing member 400. During the process of driving the force-bearing member 400 to move via the second planar display portion 503, the elastic recovery assembly 1400 can always apply a force to the force-bearing member 400 in a direction away from the reel 300, so that the force-bearing member 400 can apply a tensioning force to the flexible display panel 500, thereby flattening the entire flexible display panel 500.

[0105] Alternatively, please refer to Figures 12 and 13. Figure 12 is an exploded structural diagram of a display device provided by another embodiment of the present application, and Figure 13 is a partial structural diagram of the display device shown in Figure 12. The display device may further include: a functional device 1500 and a circuit board 1600. The functional device 1500 and the second driving assembly 1300 can both be electrically connected to the circuit board 1600. Among them, the functional device 1500 and the circuit board 1600 can both be fixed to the side of the sliding member 102 facing away from the first planar display portion 502 in the flexible display panel 500. For example, the functional device 1500 and the second driving assembly 1300 can both be electrically connected to the PCB or FPC, and then electrically connected to the main board (not shown) in the display device. In the present application, as shown in Figure 13, the functional device 1500 may include: a device body (for example, a speaker) and a first connecting plate 1501. The device body is fixed on one side of the first connecting plate 1501, and the other side of the first connecting plate 1501 is fixedly connected to the sliding member 102. The circuit board 1600 may include: a circuit board body and a second connecting plate 1601 . The circuit board body may be fixed on one side of the second connecting plate 1601 , and the other side of the second connecting plate 1601 is fixedly connected to the sliding member 102 .

[0106] In the embodiment of the present application, there are two possible ways of connecting the second driving assembly 1300 with the sliding member 102 and the second housing 200, which are schematically described in the following embodiments of the present application:

[0107] For the first possible scenario, please refer to Figures 12 and 14. Figure 14 is an exploded schematic diagram of the installation of a second drive assembly provided by another embodiment of the present application. The second drive assembly 1300 may include: a second drive motor 1301, a second transmission shaft 1302, and a second transmission member 1303. The second drive motor 1301 may be fixed to the side of the sliding member 102 that is away from the first planar display portion 502 in the flexible display panel 500, and the second drive motor 1301 may be connected to one end of the second transmission shaft 1302. A portion of the second transmission member 1303 may be sleeved on the second transmission shaft 1302, and another portion of the second transmission member 1303 may extend into the second shell 200 and be fixedly connected to the second shell 200. The length direction of the second transmission shaft 1302 may be parallel to the moving direction of the sliding member 102. The second drive motor 1301 can be electrically connected to the circuit board 1600, and the second drive motor 1301 can be configured to move along the length of the second transmission shaft 1302 when driving the second transmission shaft 1302 to rotate. In this case, after the second drive motor 1301 is fixed to the slider 102, the second drive motor 1301 can move along with the slider 102 when the display device switches between the expanded state and the retracted state. In this way, the second drive motor 1301 and the circuit board (e.g., a flexible circuit board (FPC)) are relatively stationary, which can effectively reduce the risk of circuit board failure.

[0108] For example, as shown in FIG14 , the second transmission member 1303 may include: a second transmission member body B1 and a third support base B2. The second transmission member body B1 is sleeved on the second transmission shaft 1302 and fixedly connected to the third support base B2. The third support base B2 may be fixedly connected to the second housing 200. The display device may further include: a fourth support base C1 located between the sliding member 102 and the second drive motor 1301. One side of the fourth support base C1 may be fixedly connected to the second drive motor 1301, and the other side of the fourth support base C1 may be fixedly connected to the sliding member 102 to fix the second drive motor 1301 to the sliding member 102.

[0109] For the second possible situation, please refer to Figures 12 and 15. Figure 15 is an exploded schematic diagram of the installation of another second drive assembly provided by another embodiment of the present application. The second drive assembly 1300 may include: a second drive motor 1301, a second transmission shaft 1302, and a second transmission member 1303. The second drive motor 1301 may be located on the side of the sliding member 102 away from the first planar display portion 502 in the flexible display panel 500 and may be fixedly connected to the second shell 200. The second drive motor 1301 may be connected to one end of the second transmission shaft 1302. The second transmission member 1303 may be sleeved on the second transmission shaft 1302, and the second transmission member 1303 may be connected to the side of the sliding member 102 away from the first planar display portion 502. The length direction of the second transmission shaft 1302 may be parallel to the moving direction of the sliding member 102. The second drive motor 1301 can be electrically connected to the circuit board 1600, and the second drive motor 1301 can be configured to: when driving the second transmission shaft 1302 to rotate, the second transmission member 1303 drives the sliding member 102 to move in a direction parallel to the length direction of the second transmission shaft 1302. In this case, after the second drive motor 1301 is fixed to the second shell 200 and the second transmission member 1303 is fixedly connected to the sliding member 102, the second drive motor 1301 drives the second transmission shaft 1302 to rotate while causing the second transmission member 1303 to move on the second transmission shaft 1302, thereby driving the sliding member 102 to move relative to the fixed member 101. For example, the second drive motor 1301 can be fixed to the second shell 200 via the third support base B2, and the second transmission member 1303 can be fixed to the sliding member 102 via the fourth support base C1.

[0110] Optionally, please refer to Figures 12 and 16, which is a schematic diagram of the installation of an elastic recovery component provided by another embodiment of the present application. The elastic recovery component 1400 in the display device may include: a support member 1401 fixed to the side of the second shell 200 away from the scroll 300, and a coil spring 1402 connected to the support member 1401, and one end of the coil spring 1402 can be connected to the side of the force-bearing member 400 away from the scroll 300. In this case, during the unfolding of the display device, when the force-bearing member 400 moves in the direction close to the scroll 300, it can drive at least part of the coil spring 1402 to stretch, and at the same time, the coil spring 1402 can apply a force to the force-bearing member 400 in the direction away from the scroll 300, so as to provide tension to the flexible display panel 500 through the force-bearing member 400. During the contraction of the display device, when the force-bearing member 400 moves in a direction away from the scroll 300, the extended portion of the coil spring 1402 can gradually contract, and in this process, it can still apply a force in a direction away from the scroll 300 to the force-bearing member 400, so as to provide tension to the flexible display panel 500 through the force-bearing member 400. In the present application, as shown in FIG16 , the support member 1401 in the elastic recovery assembly 1400 can have a limiting cavity c1 and an opening area c2 connected to the limiting cavity c1. At least a portion of the coil spring 1402 can be installed in the limiting cavity c1, and one end of the coil spring 1402 can extend from the opening area c2 on the support member 1401 to the outside of the limiting cavity c1 and be fastened to the force-bearing member 400. In this case, the coil spring 1402 can be installed and limited by the limiting cavity c1 in the support member 1401, so that the coil spring 1402 will not separate from the support member 1401 during the extension or contraction process.

[0111] In the embodiment of the present application, please refer to Figures 16 and 17. Figure 17 is a schematic diagram of the connection between a support member and a force-bearing member provided in the embodiment of the present application. The support member 1401 in the elastic recovery component 1400 may include: a first sub-support member D1 and a second sub-support member D2. The first sub-support member D1 may have: a first arcuate chute d1, and a third opening d2 connected to the first arcuate chute d1. The second sub-support member D2 may have a second arcuate chute d3, and a fourth opening d4 and a fifth opening d5 connected to the second arcuate chute d3. The second sub-support member D2 is fixedly connected to the first sub-support member D1 at the third opening d2 of the first sub-support member D1, and the second arcuate chute d3 in the second sub-support member D2 is connected to the first arcuate chute d1 in the first sub-support member D1 through the fourth opening d4 and the third opening d2 on the first sub-support member D1. The interconnected second curved groove d3 and the first curved groove d1 can be used to enclose a limiting cavity c1 in the support member 1401. The fifth opening d5 in the second sub-support member D2 and the area of ​​the third opening d2 in the first sub-support member D1 not covered by the second sub-support member D2 can enclose an opening area c2 in the support member 1401. For example, the curvature of the first curved groove d1 can be 180°, and the curvature of the second curved groove d3 can be 90°. The limiting cavity c1 enclosed by the first curved groove d1 and the second curved groove d3 can limit the coil spring 1402 to prevent it from separating from the support member 1401, and the coil spring 1402 can rotate smoothly within the limiting cavity c1.

[0112] Optionally, as shown in Figures 16 and 17 , the inner wall of the limiting cavity c1 in the support member 1401 may include multiple strip-shaped weight-reducing grooves c11. In this case, by providing multiple strip-shaped weight-reducing grooves c11 on the inner wall of the limiting cavity c1, the weight of the support member 1401 is reduced, facilitating a lightweight design for the display device. Furthermore, the provision of multiple weight-reducing grooves c11 can reduce the contact area between the coil spring 1402 and the inner wall of the limiting cavity c1 in the support member 1401, thereby reducing the frictional resistance of the coil spring 1402 during its extension and contraction.

[0113] It should be noted that, in other possible implementations, please refer to Figure 18, which is a schematic diagram of another connection between a support member and a force-bearing member provided in an embodiment of the present application. The support member 1401 may include: two relatively arranged fixed seats E1 and a connecting shaft E2, the fixed seat E1 can be fixedly connected to the side of the second shell 200 away from the scroll 300, the connecting shaft E2 can be located between the two fixed seats E1, and the two ends of the connecting shaft E2 can be rotatably connected to the two fixed seats E1 respectively. The coil spring 1402 can be wound around the connecting shaft E2, and one end of the coil spring 1402 can be fastened to the force-bearing member 400. In this way, during the process of extending or contracting the coil spring 1402, the connecting shaft E2 can be driven to rotate around the fixed seat, ensuring that the coil spring 1402 can be conveniently extended or contracted. In the present application, the support member 1401 may also include: two second bearings E3, the outer ring of the second bearing E3 may be fixedly connected to the fixed seat E1, and the two ends of the connecting shaft E2 may be respectively connected to the inner rings of the two second bearings E3 to achieve smooth rotation of the connecting shaft E2 around the fixed seat E1.

[0114] In an embodiment of the present application, as shown in Figures 4 and 5, the sliding member 102 fixedly connected to the first planar display portion 502 in the flexible display panel 500 can have a plurality of first guide rods 102a arranged in parallel, and the arrangement direction of the plurality of first guide rods 102a can be parallel to the extension direction of the scroll 300; the fixed member 101 can have a plurality of second guide rods 101c arranged in parallel, and the arrangement direction of the plurality of second guide rods 101c can be parallel to the extension direction of the scroll 300. Wherein, the plurality of first guide rods 102a and the plurality of second guide rods 101c are arranged in an interlaced manner. In this case, by providing a plurality of first guide rods 102a on the sliding member 102 connected to the first planar display portion 502 and providing a plurality of second guide rods 101c on the fixed member 101, the plurality of first guide rods 102a and the plurality of second guide rods 101c are arranged in an interlaced manner. In this way, during the movement of the sliding member 102 relative to the fixed member 101, the plurality of first guide rods 102a and the plurality of second guide rods 101c can slide relative to each other, thereby providing a guiding and limiting effect on the movement of the sliding member 102 relative to the fixed member 101, preventing the first planar display portion 502 connected to the sliding member 102 from tilting during movement, thereby ensuring the reliability of the display device. In the present application, a first guide groove (not shown) is formed between each two adjacent first guide rods, and a second guide rod is distributed between the first guide grooves. A second guide groove (not shown) is formed between each two adjacent second guide rods, and a first guide rod is distributed between the second guide grooves.

[0115] Alternatively, please refer to Figures 13 and 19, which is a partial structural diagram of a display device provided in another embodiment of the present application. The display device may further include: a first guide rail 1700 and a first slider 1800, wherein the first guide rail 1700 may be fixed to the fixed member 101, and the length direction of the first guide rail 1700 may be parallel to the sliding direction of the sliding member 102 relative to the fixed member 101, the first slider 1800 may be fixedly connected to the sliding member 102, and the first slider 1800 is sleeved on the first guide rail 1700 and slidably connected to the first guide rail 1700. In this case, the cooperation between the first guide rail 1700 and the first slider 1800 can ensure the stability of the sliding member 102 when moving relative to the fixed member 101, thereby improving the user experience. It should be noted that in other possible implementations, the first guide rail 1700 may also be fixed to the sliding member 102, and the length direction of the first guide rail 1700 may be parallel to the sliding direction of the sliding member 102 relative to the fixed member 101. The first slider 1800 may be fixedly connected to the fixed member 101, and the first slider 1800 is sleeved on the first guide rail 1700 and slidably connected to the first guide rail 1700. As shown in Figure 19, to facilitate the connection between the sliding member and the first slider, the display device may further include: a first adapter 1900, which is located on the side of the sliding member 102 facing away from the first planar display portion, and the first adapter 1900 is respectively connected to the first slider 1800 and the sliding member, and the first rotating member 1900 is capable of covering the back surface of the sliding member 102.

[0116] In an embodiment of the present application, please refer to FIG20 , which is a partial structural diagram of another display device provided in another embodiment of the present application. The display device may further include: a second guide rail 2000 and a second slider 2100 , wherein the second guide rail 2000 can be fixed to the second housing 200 , and the length direction of the second guide rail 2000 is parallel to the sliding direction of the force-bearing member 400 , the second slider 2100 can be fixedly connected to the force-bearing member 400 , and the second slider 2100 is sleeved on the second guide rail 2000 and slidably connected to the second guide rail 2000 . In this case, through the cooperation between the second guide rail 2000 and the second slider 2100 , the force-bearing member 400 will not deviate during movement, and the force-bearing member 400 can be limited in a direction perpendicular to the plane of the second housing 200 , thereby preventing the second planar display portion 503 in the flexible display panel 500 from arching during movement.

[0117] Alternatively, referring to Figures 12 and 21, Figure 21 is an exploded schematic diagram of a display device provided in an embodiment of the present application. The display device may further include a cover 2200 that covers the sides and back of the display device to protect the internal components of the display device and enhance the aesthetics of the display device.

[0118] In summary, embodiments of the present application provide a display device that may include: a first housing, a second housing, a scroll, a force-bearing member, and a flexible display panel. By disposing the scroll between the first and second housings, and after the first planar display portion of the flexible display panel is connected to the sliding member and the second planar display portion is connected to the force-bearing member, the rolled display portion of the flexible display panel can be wound around the scroll. The scroll can be rotatably connected to the housing, enabling indirect rotation of the rolled display portion of the flexible display panel as it passes through an axial region, thereby reducing friction in the rolled display portion of the flexible display panel and thereby lowering frictional resistance when the display device switches between an expanded state and a retracted state. Furthermore, by configuring the scroll as a plurality of sub-scrolls arranged in an array, the length of each sub-scroll is relatively short, making it easier to manufacture and ensuring axial precision of the sub-scrolls. After the plurality of sub-scrolls are mounted on the housing, the resulting scroll can maintain good coaxiality, preventing the rolled display portion of the flexible display panel from warping or collapsing when passing through the axial region, thereby ensuring a good display effect of the flexible display panel in the display device.

[0119] The present application also provides a vehicle. Please refer to Figure 22, which is a block diagram of a vehicle provided by an embodiment of the present application. The vehicle may include: a display device fixed in the cabin of the vehicle, and the display device may be any of the display devices given above. For example, the vehicle may be a vehicle or a ship or other means with a carrying function, and the display device may be fixed in the cockpit or passenger compartment of the vehicle. For example, the display device may be fixed to the vehicle dashboard, roof, or seat in the vehicle cockpit.

[0120] Thus, please refer to Figure 23, which is a schematic diagram of the effect of the telescoping and unfolding of a display device in a vehicle provided by an embodiment of the present application. When the display device is used on a vehicle (for example, a vehicle), the size of the flexible display panel extending from the display device can be flexibly adjusted, so that the flexible display panel is suitable for different usage scenarios of the vehicle. In this way, the user's entertainment and safety requirements can be met, and the installation space requirements for the vehicle are low. In particular, for large-sized flexible display screens, the size of the flexible display screen can be adjusted according to different usage scenarios in a vehicle environment. For example, when the vehicle is driving, part of the flexible display screen is accommodated in the internal space of the display device, reducing the display area of ​​the flexible display screen, and using a smaller display screen to provide driving information of the vehicle, providing a good driving field of view. When the vehicle is in an entertainment state, a larger part or all of the flexible display screen extends out of the internal space of the display device, increasing the display area and meeting the user's entertainment needs.
