These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0078] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0079] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the external structure of a display device provided in an embodiment of the present application, Figure 2 1 is a partial structural diagram 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.

[0080] 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 .

[0081] 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.

[0082] 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 .

[0083] 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, Figure 2 Only a partial structure of the second housing 200 is shown.

[0084] Please refer to Figure 3 and Figure 4 , Figure 3 is a partial structural exploded view of a display device provided by an embodiment of the present application, Figure 4 is a partial structural exploded view of another display device provided by an embodiment of the present application. The flexible display panel 500 in the display device may include: a curled display portion 501 wound around a plurality of sub-spools 301, and a first planar display portion 502 and a second planar display portion 503 located on both sides of the curled display portion 501. The first planar display portion 502 in the flexible display panel 500 may be connected to the sliding member 102, and the second planar display portion 503 may be connected to the force-bearing member 400 within the second housing 200.

[0085] In the embodiment of the present application, by providing a spool 300 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 curled display portion 501 in the flexible display panel 500 can be wound around the spool 300. The spool 300 can be rotatably connected to the housing, so that the indirect rotation of the curled display portion 501 in the flexible display panel 500 when passing through the shaft area can be realized, thereby reducing the friction of the curled display portion 501 in the flexible display panel 500 and reducing the frictional resistance when the display device switches between the unfolded state and the contracted state. In addition, by arranging the spool 300 as a plurality of sub-spools 301 arranged in an array, the length of a single sub-spool 301 is short and easy to process, and the axial accuracy of the sub-spool 301 can be ensured. After the plurality of sub-spools 301 are installed on the housing, the coaxiality of the formed spool can be ensured to be good, so that the curled display portion 501 in the flexible display panel 500 will not have adverse phenomena such as warping or collapse when passing through the shaft area, ensuring a good display effect of the flexible display panel 500 in the display device.

[0086] 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 extension and contraction process, so that the flexible display panel 500 can be suitable for 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 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, the display area of ​​the flexible display screen is reduced, and a smaller display screen is used 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.

[0087] In summary, the embodiment of the present application provides a display device, which may include: a first shell, a second shell, a scroll, a force-bearing member, and a flexible display panel. By arranging a scroll between the first shell and the second shell, and after the first planar display part of the flexible display panel is connected to the sliding member and the second planar display part is connected to the force-bearing member, the curled display part in the flexible display panel can be wound on the scroll. The scroll can be rotatably connected to the shell, which can realize the indirect rotation of the curled display part in the flexible display panel when it passes through the axis area, thereby reducing the friction of the curled display part in the flexible display panel, so as to reduce the friction resistance when the display device switches between the unfolded state and the retracted state. In addition, by setting the scroll to a plurality of sub-scrolls arranged in an array, the length of a single sub-scroll is short and easy to process, and the axial accuracy of the sub-scroll can be guaranteed. After the plurality of sub-scrolls are installed on the shell, the coaxiality of the formed scroll can be guaranteed to be good, so that the curled display part in the flexible display panel will not produce the undesirable phenomenon of warping or collapse when passing through the axis area, and the display effect of the flexible display panel in the display device is guaranteed to be good.

[0088] Optional, please refer to Figure 5 , Figure 5 1 is a schematic diagram of a connection between a sub-reel and a housing provided in 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; or, 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.

[0089] In the embodiments of the present application,Figure 5 As shown, the display device may further include: a plurality of first support seats 600 and a plurality of second support seats 700, and the plurality of first support seats 600 and the plurality of second support seats 700 may be fixedly connected to the fixing member 101. The plurality of first support seats 600 and the plurality of second support seats 700 correspond to the plurality of sub-scrolls 301 one by one, and each sub-scroll 301 may be located between the corresponding first support seat 600 and the second support seat 700, and the first end of the rotating shaft 301a in the sub-scroll 301 may be connected to the corresponding first support seat 600, and the second end of the rotating shaft 301a in the sub-scroll 301 may be connected to the corresponding second support seat 700. In this case, each sub-scroll 301 corresponds to a group of first support seats 600 and a second support group 700, and after the two ends of the rotating shaft 301a in the sub-scroll 301 are respectively connected to the first support seat 600 and the second support seat 700, the first support seat 600 and the second support seat 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, the second support seat 700 and the fixing member 101, that is, the installation accuracy of the reel 300 and the shell can be ensured. It should be noted that by adjusting the installation accuracy of the two ends of the rotating shaft 301a in the sub-reel 301 and the two support seats, and the installation accuracy of the two support seats and the fixing member 101, the deviation formed during the processing of a single long rotating shaft can be compensated.

[0090] For example, Figure 5 As shown, 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, and the first extensions 101a may be located between adjacent first sub-reels A1 and second sub-reels A2, and / or between adjacent two second sub-reels A2, and between adjacent first sub-reels A1 and second sub-reels A2. The second extension 101b may be located on the side of the first sub-reel A1 away from the second sub-reel A2. The first support seat 600 corresponding to the first sub-roll A1 can be fixedly connected to the second extension portion 101b, and the second support seat 700 corresponding to the first sub-roll A1 can be fixedly connected to the first extension portion 101a; the first support seat 600 corresponding to the second sub-roll A2 can be fixedly connected to the first extension portion 101a, and the second support seat 700 corresponding to the second sub-roll A2 can be fixedly connected to the first extension portion 101a.

[0091] It should be noted that both ends of the rotating shaft 301a in the sub-reel 301 can be rotatably connected to the corresponding first support base 600 and second support base 700, and the reel 301b can be fixedly connected to the rotating shaft 301a. In the present application, as Figure 5 shown, the display device may further include: two first bearings A3 corresponding to a set of first support bases 600 and second support bases 700. The outer ring of one first bearing A3 can be fixedly connected to the first support base 600, and the inner ring of one first bearing A3 can be sleeved on one end of the rotating shaft 301a; the outer ring of the other first bearing A3 can be fixedly connected to the second support base 700, and the inner ring of the other first bearing A3 can be sleeved on the other end of the rotating shaft 301a. In this case, both ends of the rotating shaft 301a are respectively connected to the first support base 600 and the second support base 700 through the first bearings A3, which can effectively ensure the installation accuracy of the rotating shaft 301a in each sub-reel 301 with respect to the two support bases, and can ensure the smooth sliding of the rotating shaft 301a in the sub-reel 301 relative to the two support bases.

[0092] Optionally, as Figure 5 shown, the first support base 600 and the second support base 700 located between two adjacent sub-reels 301 can be fixedly connected. That is to say, among 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 can be an integral structure.

Exemplarily, when the force-receiving member 400 is subjected to an external force and moves along the f1 axis direction, the force-receiving member 400 can drive the second end a2 of the tensioning rope 1000 to move in a direction close to the reel 300; and the tensioning rope 1000 wound around the first pulley 800 and the second pulley 900 can move under the action of the pulley, so that the first end a1 of the tensioning rope 1000 can drive the sliding member 102 to move relative to the fixing member 101 along the f2 axis direction, and further drive the entire flexible display panel 500 to unfold through the first flat display portion 502. Thus, through the cooperation of the tensioning rope 1000 and the two pulleys, while flattening the flexible display panel 500, a driving force can be provided for the movement of the sliding member 102, and further the thrust of the driving component in the required display device can be reduced, which is convenient for reducing the manufacturing cost. In addition, when the force-receiving member 400 is subjected to an external force and moves along the f3 axis direction, the force-receiving member 400 can apply a force to the second flat display portion 503 in the flexible display panel 500, and the force-receiving member 400 can drive the second end a2 of the tensioning rope 1000 to move in a direction away from the reel 300; and the tensioning rope 1000 wound around the first pulley 800 and the second pulley 900 can move under the action of the pulley, so that the first end a1 of the tensioning rope 1000 can drive the sliding member 102 to move relative to the fixing member 101 along the f4 axis direction, thereby realizing the contraction of the display device. It should be noted that after the first pulley 800 is connected to the fixing member 101, it can act as a fixed pulley to change the direction of the force on the tensioning rope 1000, and after the second pulley 900 is connected to the second housing 200, it can act as a fixed pulley to change the direction of the force on the tensioning rope.

[0095] Optionally, please refer to Figure 7 and Figure 8 , Figure 8It is a partial structural schematic diagram of another display device provided by an embodiment of the present application. The display device may further include: a first tensioning assembly (not shown in the figure) and / or a second tensioning assembly 1100. The first tensioning assembly may be respectively connected to the first pulley 800 and the fixing member 101, and the first tensioning assembly may be configured to: apply a force in a direction away from the reel 300 to the first pulley 800. The second tensioning assembly 1100 may be respectively connected to the second pulley 900 and the second housing 200, and the second tensioning assembly 1100 may be configured to: apply a force in a direction away from the reel 300 to the second pulley 900. It should be noted that the manner in which the first tensioning assembly provides a tensioning force to the tensioning rope 1000 through the first pulley 800 is the same as the manner in which the second tensioning assembly 1100 provides a tensioning force to the tensioning rope 1000 through the second pulley 900. The following embodiments will be schematically described by taking 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 bulging amount of the flexible display panel 500 in the display device is very small when switching between the unfolded state and the contracted state.

[0096] In the present application, the first tensioning assembly may include: a first elastic element, a first connecting block, and a first fastener. One end of the first fastener may be fixedly connected to the side of the fixing member away from the reel, the extending direction of the first fastener may intersect with the reel, and both the first connecting block and the first elastic element may be sleeved on the first fastener. The first elastic element may be located between the fixing member and the first connecting block. Two ends of the first elastic element may respectively abut against the fixing member and the first connecting block, and one end of the first fastener away from the fixing member may abut against the side of the first connecting block away from the fixing member. The first pulley may be rotatably connected to the first connecting block.

[0097] and / or, such as Figure 8As shown, 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 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 be sleeved on 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. One end of the second fastener 1103 away from the second housing 200 may abut against a side of the second connecting block 1102 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 connection block 1102 facing away from the second housing 200, the second elastic element 1101 located between the second housing 200 and the second connection block 1102 can apply a force in a direction away from the second housing 200 to the second connection block 1102, and then directly apply a force in a direction away from the second housing 200 to the tension rope wound on the second pulley 900 through the second pulley 900, so that the tension rope 1000 always has a pre-tensioning force. 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.

[0098] In an embodiment of the present application, the first connection block in the display device may have a first installation cavity and a first opening connected to the first installation cavity, and the first pulley may be located in the first installation cavity and may be rotatably connected to the first connection block. The first opening on the first connection block may be distributed toward the reel, and the first opening may be used for the tensioning rope to pass in and out. For example, the first end of the tensioning rope may pass through the first opening into the first installation cavity, bypass the first pulley, and then pass out from the first opening to connect with the sliding member.

[0099] and / or, if Figure 8As shown in the figure, the second connection block 1102 may have a second installation cavity b1 and a second opening b2 communicating with the second installation cavity b1. The second pulley 900 may be located in the second installation cavity b1 of the second connection block 1102 and may be rotatably connected to the second connection block 1102. The second opening b2 on the second connection block 1102 may be distributed towards the reel 300, and the second opening b2 may be used for the tensioning rope 1000 to pass through and out. For example, the second end of the tensioning rope 1000 may pass through the second opening b2 into the second installation cavity b1, bypass the second pulley 900, and then pass out of the second opening b2 to be connected to the force-bearing member 400. In this case, by providing the second installation cavity b1 and the second opening b2 communicating with the second installation cavity b1 in the second connection block 1102, the second pulley 900 is arranged in the second installation cavity b1 and rotatably connected to the second connection block 1102. In this way, the integration degree of the display device is improved, and the overall volume of the display device can be effectively reduced.

[0100] Optionally, please refer to Figure 9 , Figure 9 is a partial structural schematic diagram of another display device provided by an embodiment of the present application.

One end of the first pin shaft 802 may be connected to the fixing member 101, and the first pulley body 801 may be sleeved on the first pin shaft 802 and may be rotatably connected to the first pin shaft 802. The second pulley 900 in the display device may include: a second pulley body 901 and a second pin shaft 902. One end of the second pin shaft 902 may be connected to the second housing 200, and the second pulley body 901 may be sleeved on the second pin shaft 902 and may be rotatably connected to the second pin shaft 902. Wherein, the axial direction of the first pin shaft 802 may be perpendicular to the plane where the first housing 100 is located, and / or the axial direction of the second pin shaft 902 may be perpendicular to the plane where the second housing 200 is located. In this case, the first pulley body 801 is connected to the fixing member 101 through the first pin shaft 802, the second pulley body 901 is connected to the second housing 200 through the second pin shaft 902, the axial direction of the first pin shaft 802 is perpendicular to the plane where the first housing 100 is located, and the axial direction of the second pin shaft 902 is perpendicular to the plane where the second housing 200 is located. 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 the direction perpendicular to the plane where the first housing 100 is located and the overall thickness in the direction perpendicular to the plane where the second housing 200 is located are both small. It should be noted that in other possible implementation manners, the axial direction of the first pin shaft 802 may be parallel to the plane where the first housing 100 is located, and both ends of the first pin shaft 802 are connected to the fixing member 101; the axial direction of the second pin shaft 902 may also be parallel to the plane where the second housing is located, and both ends of the second pin shaft 902 may be connected to the second housing 200.

[0101] In the embodiments of the present application, as Figure 9 shown, the display device may further include: a first driving component 1200, the first driving component 1200 may be fixed in the second housing 200, and the first driving component 1200 may be connected to the force-receiving member 400. Among them, the first driving component 1200 may be configured to: drive the force-receiving member 400 to move in the second housing 200 in a direction perpendicular to the reel 300. In the present application, the display device further includes: a control component (not shown in the figure) electrically connected to the first driving component. After receiving a driving instruction, the control component may control the first driving component to work properly. In this case, by providing the first driving component 1200 in the display device, the first driving component 1200 can be used to drive the force-receiving member 400 to move, thereby driving the flexible display panel 500 in the display device to expand and contract, improving the automation degree of the display device.

[0102] For example, please refer to Figure 10 , Figure 10 which is a partial structural schematic diagram of another display device provided by the embodiments of the present application. The first driving component 1200 may include: a first driving motor 1201, a first transmission shaft 1202, and a first transmission member 1203. The first driving motor 1201 may be fixedly connected to the second housing 200, and the first driving motor 1201 may be connected to one end of the first transmission shaft 1202. The first transmission member 1203 may be sleeved on the first transmission shaft 1202. The first transmission shaft 1202 may be perpendicularly arranged with respect to the reel 300, and the first transmission member 1203 may be connected to the force-receiving member 400. Among them, the first driving motor 1201 may be configured to: when driving the first transmission shaft 1202 to rotate, drive the force-receiving member 400 to move along the length direction of the first transmission shaft 1202 through the first transmission member 1203. In this case, when the first driving motor 1201 works, the first driving motor 1201 can drive the first transmission shaft 1202 to rotate. During the rotation of the first transmission shaft 1202, the first transmission member 1203 can be driven to move on the first transmission shaft 1202. Further, the force-receiving member 400 can be driven to move along the length direction of the first transmission shaft 1202 through the first transmission member 1203. After the flexible display panel 500 in the display device moves to a specified position, the first driving motor 1201 stops working.

[0103] In the second alternative implementation, please refer to Figure 11 , Figure 11This is a schematic diagram showing the effect of a display device provided by an embodiment of the present application when switching between an unfolded state and a contracted state. The display device further includes: a second driving component 1300 located in the first housing 100, and an elastic recovery component 1400 fixed in the second housing 200. The second driving component 1300 can be connected to the sliding member 102 in the first housing 100, and a part of the second driving component 1300 can extend into the second housing 200 and be fixedly connected to the second housing 200. The elastic recovery component 1400 can be tightly connected to the side of the force-bearing member 400 facing away from the reel 300. Among them, the second driving component 1300 can be configured to: drive the sliding member 102 to move in the first housing 100 relative to the fixed member 102 in a direction perpendicular to the reel 300. In this case, by connecting the second driving component 1300 to the sliding member 102, the second driving component 1300 can drive the sliding member 102 to move relative to the fixed member 101, and then drive the entire flexible display panel 500 to unfold or contract through the first flat display part 502. In addition, the elastic recovery component 1400 fixed in 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 through the second flat display part 503, the elastic recovery component 1400 can always apply a force in the direction away from the reel 300 to the force-bearing member 400, so that the force-bearing member 400 can apply a tension force to the flexible display panel 500 to flatten the entire flexible display panel 500.

[0104] Optionally, please refer to Figure 12 and Figure 13 , Figure 12 This is an exploded structural schematic diagram of a display device provided by another embodiment of the present application. Figure 13 This is Figure 12 a partial structural schematic diagram of the display device shown. The display device may further include: a functional device 1500 and a circuit board 1600. Both the functional device 1500 and the second driving component 1300 can be electrically connected to the circuit board 1600. Among them, both the functional device 1500 and the circuit board 1600 can be fixed to the side of the sliding member 102 facing away from the first flat display part 502 in the flexible display panel 500. By way of example, both the functional device 1500 and the second driving component 1300 can be electrically connected to a PCB or an FPC, and then be electrically connected to the main board (not shown in the figure) in the display device. In the present application, as Figure 13As shown, the functional device 1500 may include: a device body (e.g., a speaker) and a first connecting plate 1501. The device body is fixed to 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 to 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.

[0105] In the embodiment of the present application, there are two possible cases for the connection manner of the second driving assembly 1300 with the sliding member 102 and the second housing 200. The following embodiments of the present application will schematically illustrate this:

[0106] For the first possible case, please refer to Figure 12 and Figure 14 , Figure 14 which is an installation explosion schematic diagram of a second driving assembly provided in another embodiment of the present application. The second driving assembly 1300 may include: a second driving motor 1301, a second transmission shaft 1302, and a second transmission member 1303. The second driving motor 1301 may be fixed to the side of the sliding member 102 facing away from the first flat display portion 502 in the flexible display panel 500, and the second driving motor 1301 may be connected to one end of the second transmission shaft 1302. A part of the second transmission member 1303 may be sleeved on the second transmission shaft 1302, and another part of the second transmission member 1303 may extend into the second housing 200 and be fixedly connected to the second housing 200. The length direction of the second transmission shaft 1302 may be parallel to the moving direction of the sliding member 102. Among them, the second driving motor 1301 may be electrically connected to the circuit board 1600, and the second driving motor 1301 may be configured to: when driving the second transmission shaft 1302 to rotate, move along the length direction of the second transmission shaft 1302 together with the second transmission shaft 1302. In this case, after the second driving motor 1301 is fixed to the sliding member 102, during the switching process between the unfolded state and the contracted state of the display device, the second driving motor 1301 can move with the sliding member 102. Thus, the second driving motor 1301 and the circuit board (e.g., flexible printed circuit board FPC) are relatively stationary, which can effectively reduce the risk of circuit board failure.

[0107] Exemplarily, such as Figure 14As shown in the figure, 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, and 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 driving motor 1301. One side of the fourth support base C1 may be fixedly connected to the second driving 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 driving motor 1301 to the sliding member 102.

[0108] For the second possible case, please refer to Figure 12 and Figure 15 , Figure 15 FIG. is an exploded view of the installation of another second driving assembly provided by another embodiment of the present application. The second driving assembly 1300 may include: a second driving motor 1301, a second transmission shaft 1302, and a second transmission member 1303. The second driving motor 1301 may be located on a 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 housing 200. The second driving 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 a 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. Among them, the second driving motor 1301 may be electrically connected to the circuit board 1600, and the second driving motor 1301 may be configured to: when driving the second transmission shaft 1302 to rotate, cause the second transmission member 1303 to drive the sliding member 102 to move in a direction parallel to the length direction of the second transmission shaft 1302. In this case, after fixing the second driving motor 1301 to the second housing 200 and fixedly connecting the second transmission member 1303 to the sliding member 102, when the second driving motor 1301 drives the second transmission shaft 1302 to rotate, the second transmission member 1303 moves on the second transmission shaft 1302, thereby driving the sliding member 102 to move relative to the fixing member 101. For example, the second driving motor 1301 may be fixed to the second housing 200 through the third support base B2, and the second transmission member 1303 may be fixed to the sliding member 102 through the fourth support base C1.

[0109] Optionally, please refer to Figure 12 and Figure 16 , Figure 16It is a schematic installation diagram 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 housing 200 facing away from the reel 300, and a torsion spring 1402 connected to the support member 1401. One end of the torsion spring 1402 may be connected to the side of the force-receiving member 400 facing away from the reel 300. In this case, during the unfolding process of the display device, when the force-receiving member 400 moves in the direction close to the reel 300, it can drive at least part of the torsion spring 1402 to stretch. At the same time, the torsion spring 1402 can apply a force in the direction away from the reel 300 to the force-receiving member 400, so as to provide a tension force to the flexible display panel 500 through the force-receiving member 400. And during the contraction process of the display device, when the force-receiving member 400 moves in the direction away from the reel 300, the stretched part of the torsion spring 1402 can gradually contract, and still be able to apply a force in the direction away from the reel 300 to the force-receiving member 400 during this process, so as to provide a tension force to the flexible display panel 500 through the force-receiving member 400. In the present application, as Figure 16 shown, the support member 1401 in the elastic recovery component 1400 may have a limiting cavity c1 and an opening area c2 communicating with the limiting cavity c1. At least part of the torsion spring 1402 may be installed in the limiting cavity c1, and one end of the torsion spring 1402 may extend out of the opening area c2 on the support member 1401 to be fixedly connected to the force-receiving member 400 outside the limiting cavity c1. In this case, the torsion spring 1402 can be installed and limited by the limiting cavity c1 in the support member 1401, so that the torsion spring 1402 will not separate from the support member 1401 during the stretching or contracting process.

[0110] In the embodiment of the present application, please refer to Figure 16 and Figure 17 , Figure 17It is a schematic diagram of the connection between a support member and a force-bearing member provided by an embodiment of the present application. The support member 1401 in the elastic recovery assembly 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 arc-shaped chute d1, and a third opening d2 communicating with the first arc-shaped chute d1. The second sub-support member D2 may have a second arc-shaped chute d3, and a fourth opening d4 and a fifth opening d5 communicating with the second arc-shaped chute d3. Among them, 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. The second arc-shaped chute d3 in the second sub-support member D2 communicates with the first arc-shaped 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. And the mutually communicating second arc-shaped chute d3 and the first arc-shaped chute d1 can be used to enclose a limiting cavity c1 in the support member 1401. The area in the fifth opening d5 of the second sub-support member D2 and the third opening d2 of the first sub-support member D1 that is not covered by the second sub-support member D2 can enclose an opening area c2 in the support member 1401. For example, the radian of the first arc-shaped chute d1 can be 180°, and the radian of the second arc-shaped chute d3 can be 90°. The limiting cavity c1 formed by the first arc-shaped chute d1 and the second arc-shaped chute d3 can limit the torsion spring 1402 to prevent it from detaching from the support member 1401, and the torsion spring 1402 can rotate smoothly within the limiting cavity c1.

[0111] Optionally, as Figure 16 and Figure 17 shown, there may be a plurality of strip-shaped weight-reducing grooves c11 on the inner wall of the limiting cavity c1 in the support member 1401. In this case, by providing a plurality of strip-shaped weight-reducing grooves c11 on the inner wall of the limiting cavity c1, the weight of the support member 1401 is relatively small, which is convenient for the lightweight design of the display device. And opening a plurality of weight-reducing grooves c11 can reduce the contact area between the torsion spring 1402 and the inner wall of the limiting cavity c1 in the support member 1401, thereby reducing the frictional resistance of the torsion spring 1402 during the stretching and contracting processes.

[0112] It should be noted that in other possible implementation manners, please refer to Figure 18 , Figure 18It is another connection schematic diagram of 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 may be fixedly connected to the side of the second shell 200 away from the reel 300, the connecting shaft E2 may be located between the two fixed seats E1, and the two ends of the connecting shaft E2 may be respectively rotatably connected to the two fixed seats E1. The coil spring 1402 may be wound on the connecting shaft E2, and one end of the coil spring 1402 may be fastened to the force-bearing member 400. In this way, the connecting shaft E2 can be driven to rotate around the fixed seat during the extension or contraction of the coil spring 1402, 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, so as to realize the smooth rotation of the connecting shaft E2 around the fixed seat E1.

[0113] In the embodiments of the present application, Figure 4 and Figure 5 As shown, the sliding member 102 fixedly connected to the first planar display portion 502 in the flexible display panel 500 may have a plurality of first guide rods 102a arranged in parallel, and the arrangement direction of the plurality of first guide rods 102a may be parallel to the extension direction of the reel 300; the fixing member 101 may have a plurality of second guide rods 101c arranged in parallel, and the arrangement direction of the plurality of second guide rods 101c may be parallel to the extension direction of the reel 300. Among them, 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 arranging a plurality of first guide rods 102a on the sliding member 102 connected to the first planar display portion 502, and arranging a plurality of second guide rods 101c on the fixing 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, which can guide and limit the movement of the sliding member 102 relative to the fixed member 101, thereby preventing the first plane display portion 502 connected to the sliding member 102 from tilting during the movement, thereby ensuring the reliability of the display device. In the present application, a first guide groove (not shown in the figure) 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 in the figure) is formed between each two adjacent second guide rods, and a first guide rod is distributed between the second guide grooves.

[0114] Optional, please refer to Figure 13 and Figure 19 , Figure 19It is a partial structural schematic diagram of a display device provided by another embodiment of the present application. The display device may further include: a first guide rail 1700 and a first slider 1800. The first guide rail 1700 may be fixed on the fixing 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 fixing 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 of the first guide rail 1700 and the first slider 1800 can ensure the stability of the sliding member 102 when moving relative to the fixing member 101, improving the user experience. It should be noted that in other possible implementation manners, the first guide rail 1700 may also be fixed on 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 fixing member 101. The first slider 1800 may be fixedly connected to the fixing 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 Figure 19 shown, in order to facilitate the connection between the sliding member and the first slider, the display device may further include: a first adapter 1900. The first adapter is located on the side of the sliding member 102 away from the first flat 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 can cover the back surface of the sliding member 102.

[0115] In the embodiment of the present application, please refer to Figure 20 , Figure 20 It is a partial structural schematic diagram of another display device provided by another embodiment of the present application. The display device may further include: a second guide rail 2000 and a second slider 2100. The second guide rail 2000 may be fixed on 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 may 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 of the second guide rail 2000 and the second slider 2100, the force-bearing member 400 will not deviate during the movement, and the force-bearing member 400 can be limited in the direction perpendicular to the plane where the second housing 200 is located, thereby preventing the second flat display portion 503 in the flexible display panel 500 from arching during the movement.

[0116] Optionally, please refer to Figure 12 and Figure 21 , Figure 21It is an exploded view of a display device provided by an embodiment of the present application. The display device may further include: a covering member 2200, which can cover the side and back of the display device to protect the internal components of the display device and improve the aesthetics of the display device.

[0117] In summary, the embodiment of the present application provides a display device, which may include: a first housing, a second housing, a reel, a force-bearing member, and a flexible display panel. By arranging a reel between the first housing and the second housing, and connecting the first planar display portion of the flexible display panel to a sliding member and the second planar display portion to a force-bearing member, the curled display portion in the flexible display panel can be wound around the reel. The reel can be rotatably connected to the housing, enabling the indirect rotation of the curled display portion in the flexible display panel when passing through the shaft area, thereby reducing the friction of the curled display portion in the flexible display panel and reducing the frictional resistance when the display device switches between the unfolded state and the contracted state. Additionally, by arranging the reel as a plurality of sub-reels arranged in an array, the length of a single sub-reel is short and easy to process, and the axial accuracy of the sub-reel can be ensured. After multiple sub-reels are installed on the housing, the coaxiality of the formed reel can be ensured to be good, so that the curled display portion in the flexible display panel will not produce adverse phenomena such as warping or collapse when passing through the shaft area, ensuring a good display effect of the flexible display panel in the display device.

[0118] The embodiment of the present application also provides a means of transportation. Please refer to Figure 22 , Figure 22 It is a block diagram of a means of transportation provided by an embodiment of the present application. The means of transportation may include: a display device fixed in the cabin of the means of transportation, and the display device may be any of the display devices given above. By way of example, the means of transportation 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 cabin of the means of transportation. For example, the display device may be fixed on the vehicle instrument panel, the roof, or the seat in the vehicle cockpit.

[0119] Thus, please refer to Figure 23 , Figure 23It is a schematic diagram of the telescoping and unfolding effects of a display device in a vehicle provided by an embodiment of the present application. When the display device is used in a vehicle (e.g., a car), it can flexibly adjust the size of the flexible display panel extended from the display device, enabling the flexible display panel to be suitable for different usage scenarios of the vehicle. Thus, it can meet the requirements of user entertainment and safety, and has a low requirement for the installation space of the vehicle. Especially for large-sized flexible display screens, their sizes can be adjusted according to different usage scenarios in the in-vehicle environment. For example, when the vehicle is in motion, part of the flexible display screen is housed 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, thus providing a good driving 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 to meet the entertainment needs of users.

[0120] It should be noted that in the drawings, the sizes of layers and regions may be exaggerated for clarity of illustration. Also, it can be understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be an intermediate layer. Additionally, it can be understood that when an element or layer is referred to as being "under" another element or layer, it can be directly under the other element, or there may be more than one intermediate layer or element. Further, it can also be understood that when a layer or element is referred to as being "between" two layers or two elements, it can be the only layer between the two layers or two elements, or there may be more than one intermediate layer or element. Like reference numerals throughout the specification indicate like elements.

[0121] In the present application, the terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance. The term "plurality" refers to two or more, unless otherwise clearly defined.

[0122] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
