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

[0068] 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.

[0069] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of the structure of a display device provided in an embodiment of the present application, and Figure 2 is a schematic diagram of the partial structure of the display device shown in Figure 1. The display device can be any product with a display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, navigator, or the device body of a wearable device. The display device may include a main support assembly 100, two rotating support assemblies 200, a hinge 300, and a flexible display panel 400.

[0070] The two rotation support assemblies 200 in the display device may be distributed on both sides of the main body support assembly 100 in the first direction f1.

[0071] The hinge 300 in the display device can be distributed between the main support assembly 100 and the rotation support assembly 200 in the first direction f1, that is, one hinge 300 can be distributed between each rotation support assembly 200 and the main support assembly 100. The hinge 300 can include: a support base 301 and at least two flip assemblies 302. The support base 302 can extend along a second direction f2 that intersects the first direction f1 (for example, the first direction can be perpendicular to the second direction). The at least two flip assemblies 302 are arranged opposite to each other in the first direction f1 and are both connected to the support base 301. One of the at least two flip assemblies 302 can be connected to the main support assembly 100, and the other flip assembly can be connected to the rotation support assembly 200. For example, the hinge 300 may include four flip assemblies 302, wherein two flip assemblies 302 are distributed on one side of the support base 301 along the first direction f1 and are both connected to the support base 301 and the main support assembly 100, and the other two flip assemblies 302 are distributed on the other side of the support base 301 and are both connected to the support base 301 and the rotation support assembly 100.

[0072] The back of the flexible display panel 400 in the display device can be fixedly connected to the main support assembly 100, the support base 301 and the rotation support assembly 200. It should be noted that the back of the flexible display panel 400 is the side opposite to the display surface of the flexible display panel 400.

[0073] In an embodiment of the present application, a hinge 300 is provided between the main support assembly 100 and the rotating support assembly 200 in the display device, and at least two flip assemblies 302 in the hinge 300 are distributed on both sides of the support base 301 and connected to the support base 301. One flip assembly 302 is rotatably connected to the main support assembly 100, and the other flip assembly 302 is rotatably connected to the rotating support assembly 200. When the display device switches between the unfolded state and the folded state, under the action of an external force, the hinge 300 can rotate a certain angle relative to the main support assembly 100, and the rotating support assembly 200 can also rotate a certain angle relative to the hinge 300. At this time, the flexible display panel 400 can also be folded into different shapes under the action of the hinge 300 and the rotating support assembly 200. In this way, the display device equipped with the flexible display panel 400 in the present application has a variety of different folding shapes, making the display device more flexible and improving the user experience. Here, during the switching between the unfolded state and the folded state of the display device, the angle at which the hinge 300 rotates relative to the main support assembly 100 and the angle at which the rotation support assembly 200 rotates relative to the hinge 300 may both be acute angles.

[0074] For example, please refer to Figure 3, which is a schematic diagram of the effect of a display device provided by an embodiment of the present application switching between an unfolded state and a folding state. When the display device is in the unfolded state, the side of the main support assembly 100 facing the flexible display panel 400, the side of the support base 301 in the hinge 300 facing the flexible display panel 400, and the side of the rotation support assembly 200 facing the flexible display panel 400 can all be flush. When the display device switches from the unfolded state to the folded state, the hinge 300 and the rotation support assembly 200 located on one side of the main support assembly 100 are used as an example for schematic description: the direction in which the hinge 300 rotates relative to the main support assembly 100 via the flip assembly 302 can be the same as the direction in which the rotation support assembly 200 rotates relative to the hinge 300 via the flip assembly 302. It should be noted that the basic structural composition and movement principle of the rotation support assembly 200 and the hinge 300 distributed on opposite sides of the main support assembly 100 are the same, and reference can be made to the above description, which will not be repeated here.

[0075] In summary, an embodiment of the present application provides a display device, which may include: a main support assembly, two rotation support assemblies, a hinge, and a flexible display panel. By setting a hinge between the main support assembly and the rotation support assembly in the display device, at least two flip assemblies in the hinge are distributed on both sides of the support base and connected to the support base, another flip assembly is rotationally connected to the main support assembly, and another flip assembly is rotationally connected to the rotation support assembly. When the display device switches between the unfolded state and the folded state, under the action of an external force, the hinge can rotate a certain angle relative to the main support assembly, and the rotation support assembly can also rotate a certain angle relative to the hinge. At this time, the flexible display panel can also be folded into different shapes under the driving action of the hinge and the rotation support assembly. In this way, the display device equipped with a flexible display panel in the present application has a variety of different folding forms, which makes the display device more flexible to use and improves the user experience.

[0076] Optionally, please refer to Figures 4 and 5. Figure 4 is a schematic diagram of a partial structure of a display device provided in an embodiment of the present application, and Figure 5 is a cross-sectional view of a partial structure of the display device. The flip assembly 302 in the hinge 300 may include: a rotating arm, a first end of which may be fixedly connected to the support base 301, and a second end of the rotating arm may be rotatably connected to a target support assembly, which may be a main support assembly 100 or a rotating support assembly 200. In the present application, the flip assembly 302 connected to the main support assembly 100 may be a first flip assembly 302a, and the flip assembly 302 connected to the rotating support assembly 200 may be a second flip assembly 302b. The first flip assembly 302a may include a first rotating arm 2a, a first end of which may be fixedly connected to one end of the support base 301, and a second end of which may be rotatably connected to the main support assembly 100. The second flip assembly 302b may include a second rotating arm 2b, a first end of which may be fixedly connected to the other end of the support base 301, and a second end of which may be rotatably connected to the rotation support assembly 200. In this case, by disposing the first rotating arm 2a and the second rotating arm 2b at opposite ends of the support base 301, respectively, and the first rotating arm 2a being rotatably connected to the main support assembly 100, and the second rotating arm 2b being rotatably connected to the rotation support assembly 200, the relative rotation between the main support assembly and the hinge, and between the hinge and the rotation support assembly, can be conveniently achieved through the rotational connection between the rotating arms and the target support assembly.

[0077] In the embodiment of the present application, as shown in Figures 4 and 5, the rotating arm in the flip assembly 302 can be a curved slide, and the side of the target support assembly facing the support base 301 can have a first curved slide that cooperates with the curved slide, and at least a portion of the curved slide can be located within the first curved slide and rotatably connected to the first curved slide. In the present application, the first rotating arm 2a can be a first curved slide a1, and the side of the main support assembly 100 facing the support base 301 can have a first curved slide A1 that cooperates with the first curved slide a1; the second rotating arm 2b can be a second curved slide b1, and the side of the rotating support assembly 200 facing the support base 301 can have a first curved slide A2 that cooperates with the second curved slide b1. Taking the first curved slide a1 and the first curved groove A1 in the main support assembly 100 as an example, when the first curved slide a1 slides in the first curved groove A1, the support seat 301 can rotate in two different directions relative to the main support assembly 100, thereby changing the angle between the hinge 300 and the main support assembly 100, thereby realizing the folding or unfolding of the display device.

[0078] Optionally, the target support assembly may include: a support portion and a first connecting block, the support portion may have a mounting groove on a side close to the support seat 301, and the first connecting block may be fixed in the mounting groove. The first connecting block may have a first arc-shaped slide groove on the side facing the rotating arm, and the side of the first connecting block facing the flexible display panel may be flush with the side of the support portion facing the flexible display panel. The strength of the first connecting block is greater than the strength of the support portion. In this case, by providing a mounting groove on the support portion in the target support assembly, the first connecting block can be fixed in the mounting groove, and it is ensured that the side of the first connecting block facing the flexible display panel is flush with the side of the support portion facing the flexible display panel, so that the flatness of the flexible display panel is better. In addition, the strength of the first connecting block is greater than the strength of the support portion, and the first arc-shaped slide groove is provided on the first connecting block to ensure that the first arc-shaped slide groove will basically not deform during the sliding process of the arc slide and the first arc-shaped slide groove, thereby ensuring that the sliding stability of the support seat and the target support assembly is better. For example, the first connection block may be made of steel, and the support portion may be made of aluminum, to ensure connection stability while keeping the weight of the entire device low.

[0079] In the present application, as shown in Figures 4 and 5 , the main support assembly 100 may include a first support portion 101 and a first connecting block B1. The side of the first support portion 101 near the support base 301 may have a first mounting groove c1, and the first connecting block B1 may be fixed in the first mounting groove c1. The side of the first connecting block B1 facing the first rotating arm 2a may have a first curved groove A1, and the side of the first connecting block B1 facing the flexible display panel 400 may be flush with the side of the first support portion 101 facing the flexible display panel 400. The rotating support assembly 200 may include a second support portion 201 and a first connecting block B2. The side of the second support portion 201 near the support base 301 may have a second mounting groove c2, and the first connecting block B2 may be fixed in the second mounting groove c2. The side of the first connecting block B2 facing the second rotating arm 2b may have a first curved groove A2, and the side of the first connecting block B2 facing the flexible display panel 400 may be flush with the side of the second support portion 201 facing the flexible display panel 400.

[0080] In an embodiment of the present application, a side of the inner wall of the mounting groove on the support portion facing the support seat (i.e., a side of the side wall of the mounting groove facing the support seat) may have a first positioning member, and a side of the inner wall of the mounting groove facing the flexible display panel (i.e., the bottom wall of the mounting groove) may have a through hole. The first connecting block may have a second positioning member that is engaged with the first positioning member, and a connecting hole that is connected to the through hole, and the connecting hole may be closer to the flexible display panel relative to the through hole. The target support assembly may also include: a fastener, one end of which may be passed through the through hole and fastened to the connecting hole on the first connecting block. In this case, the cooperation of the first positioning member and the second positioning member can effectively ensure the installation accuracy of the first connecting block in the mounting groove. And because the arrangement direction of the first positioning member and the second positioning member is perpendicular to the arrangement direction of the through hole and the connecting hole, the undesirable phenomenon of local warping of the first connecting block can be effectively prevented while connecting the support portion and the first connecting block with fewer fasteners. For example, the number of the fastener can be one, and the number of the through-hole on the support portion and the number of the connecting hole on the first connecting block can both be one, thereby achieving a better sealing effect on the interior of the display device. For example, one of the first positioning member and the second positioning member can be a positioning post, and the other can be a positioning hole. The embodiments of this application are schematically described using the example of the first positioning member being a positioning hole and the second positioning member being a positioning post.

[0081] In the present application, as shown in Figures 4 and 5, the inner wall of the first mounting groove c1 of the first support portion 101 may have a first positioning member 101a on one side facing the support seat 301, and the inner wall of the first mounting groove c1 may have a first through hole 101b on one side facing the flexible display panel 400. The first connecting block B1 may have a second positioning member B11 that is engaged with the first positioning member 101a, and a first connecting hole (not shown in the figure) that is connected to the first through hole 101b. The first connecting hole may be closer to the flexible display panel 400 than the first through hole 101b. The main support assembly 100 may also include: a first fastener (not shown in the figure), one end of which may pass through the first through hole 101b and be fastened to the first connecting hole on the first connecting block B1. In this way, the first connection block B1 and the first mounting groove c1 are positioned by the cooperation of the first positioning member 101a and the second positioning member B11. The first fastener passes through the first through-hole 101b and connects with the first connecting hole, thereby achieving a fixed connection between the first connection block B1 and the first support portion 101. The inner wall of the second mounting groove c2 of the second support portion 201, facing the support seat 301, may have a first positioning member (not shown), and the inner wall of the second mounting groove c2, facing the flexible display panel 400, may have a second through-hole 201b. The first connection block B2 may have a second positioning member B21 that engages with the first positioning member, and a second connecting hole (not shown) that communicates with the second through-hole 201b. This second connecting hole may be closer to the flexible display panel 400 than the second through-hole 201b. The rotating support assembly 200 may also include a second fastener (not shown), one end of which may pass through the second through-hole 201b and be fastened to the second connecting hole on the first connection block B2. In this way, the first connection block B2 and the second mounting groove c2 are positioned by the cooperation of the first positioning member and the second positioning member B21, and the second fastener passes through the second through hole 201b and is connected to the second connection hole to achieve a fixed connection between the first connection block B2 and the second support part 201.

[0082] Optionally, the first arc-shaped slide groove on the target support assembly may have a slide groove opening for the arc-shaped slide plate to enter, and a limiting blind end arranged opposite to the slide groove opening, and the inner wall of the first arc-shaped slide groove may have a first limiting protrusion. The end of the arc-shaped slide plate may have a second limiting protrusion that matches the first limiting protrusion. Wherein, after the display device is in the folded state, the end of the arc-shaped slide plate may abut against the limiting blind end of the first arc-shaped slide groove; after the display device is in the unfolded state, the first limiting protrusion and the second limiting protrusion abut. In the present application, as shown in Figures 4 and 5, the first arc-shaped slide plate a1 and the first arc-shaped slide groove A1 are used as examples for schematic description: the first arc-shaped slide groove A1 on the main support assembly 100 may have a slide groove opening for the first arc-shaped slide plate a1 to enter, and a first limiting blind end d1 arranged opposite to the slide groove opening, and the inner wall of the first arc-shaped slide groove A1 may have a first limiting protrusion d2. The end of the first curved slide a1 can have a second limiting protrusion d3 that matches the first limiting protrusion d2. Thus, when the display device switches from the unfolded state to the folded state, the first curved slide a1 can slide within the first curved chute A1 toward the first limiting blind end d1 of the first curved chute A1. After rotating to the target angle, the end of the first curved slide a1 can abut against the limiting blind end d1 of the first curved chute A1. This prevents excessive rotation of the support base 301, and the limiting blind end d1 of the first curved chute A1 facing the side of the flexible display panel 400 can effectively support the flexible display panel 400. During the transition of the display device from the folded state to the unfolded state, the first curved slide a1 drives the second limiting protrusion d3 to move toward the first limiting protrusion d2 within the first curved chute A1. When the display device is rotated to the flattened state, one side of the second limiting protrusion d3 can abut against one side of the first limiting protrusion d2 to achieve position limiting in the flattened state. It should be noted that the limiting principle of the second curved slide b1 and the first curved chute A2 via the first limiting protrusion and the second limiting protrusion can refer to the limiting principle of the first curved slide a1 and the first curved chute A1 described above, and will not be repeated here.

[0083] In the embodiment of the present application, please refer to Figures 6, 7 and 8. Figure 6 is a partial structural exploded schematic diagram of a display device provided in the embodiment of the present application, Figure 7 is a partial structural schematic diagram of another display device provided in the embodiment of the present application, and Figure 8 is a cross-sectional view of another display device provided in the embodiment of the present application. The flip assembly 302 may also include: a driving rod and a first protrusion, one end of the driving rod can be rotatably connected to the support base 301, and the other end of the driving rod can be fixedly connected to the first protrusion. Wherein, the target support assembly can have a linear slide groove on one side facing the support base 301, the other end of the driving rod can extend into the linear slide groove, and the first protrusion can slide relative to the target support assembly in the linear slide groove. In this case, during the process of the support base rotating with the target support assembly through the rotating arm, one end of the driving rod can rotate relative to the support base, and the first protrusion fixed on the other end of the driving rod can slide in the linear slide groove in the target support assembly. It should be noted that the rotation axis of the driving rod relative to the support base is parallel to but not overlapped with the rotation axis of the arc slide relative to the first arc slide groove.

[0084] In the present application, as shown in Figures 6, 7, and 8, the first flip assembly 302a may include: a first drive rod 2c and a first protrusion 2d, one end of the first drive rod 2c may be rotatably connected to the support base 301, and the other end of the first drive rod 2c may be fixedly connected to the first protrusion 2d. The main body support assembly 100 may have a first linear slide e1 on the side facing the support base 301, the other end of the first drive rod 2c may extend into the first linear slide e1, and the first protrusion 2d may slide relative to the main body support assembly 100 in the first linear slide e1. The second flip assembly 302b may include: a second drive rod 2e and a first protrusion 2f, one end of the second drive rod 2e may be rotatably connected to the support base 301, and the other end of the second drive rod 2e may be fixedly connected to the first protrusion 2f. The rotating support assembly 200 may have a second linear groove e2 on one side facing the support seat 301, the other end of the second driving rod 2e may extend into the second linear groove e2, and the first protrusion 2f may slide relative to the rotating support assembly 200 in the second linear groove e2.

[0085] Optionally, as shown in Figures 6, 7 and 8, the hinge 300 may further include: two connecting shafts 303 corresponding to the two flip assemblies 302 arranged opposite each other, both of which can be fixed in the support base 301, and one end of the driving rod in each flip assembly can be sleeved on the corresponding connecting shaft and can be rotatably connected to the corresponding connecting shaft. In this case, by fixing two connecting shafts 303 distributed side by side on the side of the support base 301 away from the flexible display panel 400, one end of the driving rod can be sleeved on the connecting shaft and rotatably connected to the connecting shaft, thereby realizing the rotational connection between the driving rod and the support base. For example, one end of the first driving rod 2c can be sleeved on one connecting shaft 303 and rotatably connected to this connecting shaft; one end of the second driving rod 2e can be sleeved on another connecting shaft 303 and rotatably connected to this connecting shaft.

[0086] In an embodiment of the present application, the end of the drive rod in the flip assembly facing away from the first protrusion may have multiple synchronized external teeth. The two drive rods in the two oppositely arranged flip assemblies are meshed through the synchronized external teeth. In the present application, as shown in Figures 6, 7, 8, and 9, Figure 9 is a schematic diagram of the effect of a display device in a bent state provided by an embodiment of the present application. The end of the first drive rod 2c facing away from the first protrusion 2d may have multiple first synchronized external teeth 2g, and the end of the second drive rod 2e facing away from the first protrusion 2f may have multiple second synchronized external teeth 2h. The multiple first synchronized external teeth 2g and the multiple second synchronized external teeth 2h are meshed. Thus, during the rotation of the support base 301 relative to the main support assembly 100, one end of the first drive rod 2c rotates about the connecting shaft 303. Simultaneously, through the meshing action of the first synchronized external teeth 2g and the second synchronized external teeth 2h, the second drive rod 2e is driven to rotate about the connecting shaft 303, thereby driving the rotating support assembly 200 to rotate relative to the support base 301. This allows for synchronized rotation of the two, enhancing the user experience.

[0087] Optionally, as shown in Figures 6, 7 and 8, the hinge 300 may further include: a torsion mechanism 304 connected to the two connecting shafts 303, and the torsion mechanism 304 may be configured to provide a damping force when the target support assembly rotates relative to the support seat. In this case, by providing the torsion mechanism 304 in the hinge 300, a damping force can be provided when the target support assembly rotates relative to the support seat, that is, the damping effect of the display device when switching between the folded state and the unfolded state is increased. In the present application, the torsion mechanism 304 may include: a torsion piece and an elastic element sleeved on each connecting shaft 303, the torsion piece may abut against the portion of the drive rod sleeved on the connecting shaft, and the elastic element may be distributed on the side of the torsion piece away from the drive rod. Wherein, the two torsion pieces sleeved on the two connecting shafts are fixedly connected. In this case, the elastic element can be used to apply a force to the torsion member, so that the torsion member can simultaneously apply a squeezing force to the drive rods sleeved on the two connecting shafts, thereby providing a damping force for the rotation of the main support assembly relative to the support base, and for the rotation of the rotation support assembly relative to the support base, thereby achieving a hovering function at different angles. For example, please refer to Figures 7 and 10. Figure 10 is a partial exploded schematic diagram of the structure of another display device provided in an embodiment of the present application. The torsion mechanism 304 may include: a first torsion member 304a and a first elastic element 304b sleeved on a connecting shaft 303, wherein the first torsion member 304a can abut against the portion of the first drive rod 2c sleeved on the connecting shaft, and the first elastic element 304b is located on the side of the first torsion member 304a facing away from the first drive rod 2c; the torsion mechanism 304 may also include: a second torsion member 304c and a second elastic element 304d sleeved on another connecting shaft, wherein the second torsion member 304c can abut against the portion of the second drive rod 2e sleeved on the connecting shaft 303, and the second elastic element 304d is located on the side of the second torsion member 304c facing away from the second drive rod 2e. It should be noted that the first elastic element 304b and the second elastic element 304d may be coil springs or multiple disc springs stacked in layers, and this embodiment of the application does not specifically limit this.

[0088] In an embodiment of the present application, the portion of the drive rod that is sleeved on the connecting shaft can have multiple first abutments on the side facing the torsion member, and the torsion member can have multiple second abutments on the side facing the drive rod. For example, one of the first abutment and the second abutment can be a protrusion, and the other can be a depression. As shown in the figure, the portion of the drive rod that is sleeved on the connecting shaft can have multiple first protrusions on the side facing the torsion member, and the torsion member can have multiple first depressions on the side facing the drive rod. For example, taking the multiple first protrusions 2j on the first drive rod 2c and the multiple first depressions 2k on the first torsion member 304a as an example, when the display device is in a fully expanded state, the first protrusion 2j on the first drive rod 2c can be located within the first depression 2k on the first torsion member 304a, so that the display device can maintain this specific angle, and when the user touches or presses the flexible screen, the display device will not be easily folded under the action of external force. When the display device is in a fully folded state, the first protrusion 2j on the first drive rod 2c can be located within the first recess 2k on the first torsion member 304a, allowing the display device to maintain this specific angle. When a user touches or presses the flexible screen, the display device will not be randomly unfolded under the action of external forces, thereby ensuring the safety of the display device. It should be noted that the coordination of multiple first protrusions and multiple first recesses can also achieve the display device hovering at any position between fully unfolded and fully folded.

[0089] Optionally, the torsion mechanism 304 in the hinge 300 may further include: an auxiliary torsion piece sleeved on each connecting shaft 303, the auxiliary torsion piece may be distributed on the side of the driving stem away from the torsion piece, and the auxiliary torsion piece may abut against the portion of the driving rod sleeved on the connecting shaft. The two auxiliary torsion pieces sleeved on the two connecting shafts are fixedly connected. In this case, by providing an auxiliary torsion piece in the torsion mechanism, the degree of compression of the elastic element can be ensured through the cooperation of the auxiliary torsion piece and the torsion piece, thereby obtaining sufficiently large damping. In the present application, as shown in Figures 7 and 10, the torsion mechanism 304 includes: a first auxiliary torsion piece 304e sleeved on one connecting shaft 303, and a second auxiliary torsion piece 304f sleeved on the other connecting shaft 303, the first auxiliary torsion piece 304e and the second auxiliary torsion piece 304f being fixedly connected. It should be noted that the structure of the auxiliary torsion member can be the same as that of the torsion member, and the principle of generating torque by the abutment between the auxiliary torsion member and the driving rod can be the same as the principle of generating torque by the abutment between the torsion member and the driving rod, which will not be repeated here.

[0090] In an embodiment of the present application, as shown in Figures 7 and 10, the support base 301 in the hinge 300 can have a first limiting plate 301a and a second limiting plate 301b arranged opposite to each other. The arrangement direction of the first limiting plate 301a and the second limiting plate 301b can be parallel to the extension direction of the support base 301, and the two ends of the connecting shaft 303 can be connected to the first limiting plate 301a and the second limiting plate 301b respectively. The auxiliary torsion member, drive rod, torsion member and elastic element in the torsion mechanism 304 are all arranged in sequence between the first limiting plate 301a and the second limiting plate 301b, and the end of the elastic element facing away from the torsion member can abut against the second limiting plate. For example, the first limiting plate 301a can be located at the end of the support base 301, and the second limiting plate 301b can be a certain distance away from the first limiting plate 301a. The distance can be set according to the size of the auxiliary torsion member, drive rod, torsion member and elastic element in the torsion mechanism. In the present application, as shown in FIG10 , the first limiting plate 301a may have two first through holes g1, and the second limiting plate 301b may have two second through holes g2 corresponding to the two first through holes g1. The torque mechanism 304 may further include a first locking member 304g and a second locking member 304h. One end of a connecting shaft 303 may pass through one of the first through holes g1 and one of the second through holes g2 in sequence and then be located on a side of the second limiting plate 301b facing away from the first limiting plate 301a. The first locking member 304g may be mounted on one end of a connecting shaft 303 and abut against the second limiting plate 301b. The other end of a connecting shaft 303 may be located on a side of the first limiting plate 301a facing away from the second limiting plate 301b and may be securely connected to the second limiting plate 301b, so that the connecting shaft 303 does not detach from the support base 301 and does not rotate relative to the support base 301. One end of the other connecting shaft 303 can sequentially pass through the other first through-hole g1 and the other second through-hole g2 and then be located on the side of the second limiting plate 301b facing away from the first limiting plate 301a. The second locking member 304h can be clamped onto one end of the other connecting shaft 303 and abut against the second limiting plate 301b. The other end of the other connecting shaft 303 can be located on the side of the first limiting plate 301a facing away from the second limiting plate 301b and can be tightly connected to the second limiting plate 301b, so that this connecting shaft 303 cannot be separated from the support base and cannot rotate relative to the support base 301.

[0091] In the present application, as shown in FIG10 , the hinge 300 may further include two protective side panels 305 connected to both ends of the support base 301. The support base 301 may be located between the two protective side panels 305 in the second direction f1. The side surfaces of the target support assembly may include escape grooves that cooperate with the protective side panels 305. For example, the side surfaces of the main support assembly 100 may include a first escape groove 103 that cooperates with the protective side panels 305, and the side surfaces of the rotation support assembly 200 may include a second escape groove 203 that cooperates with the protective side panels 305. In this case, by providing protective side panels 305 at both ends of the support base 301, the protective side panels 305 can protect both sides of the support base 301. During the bending process of the display device, the first avoidance groove 103 on the main support assembly 100 can avoid the protective side panels 305 without interfering with the normal rotation of the main support assembly 100. At the same time, the second avoidance groove 203 on the rotation support assembly 200 can avoid the protective side panels 305 without interfering with the normal rotation of the rotation support assembly 200. In other possible implementations, the other ends of the two connecting shafts 303 can be fixedly connected to the protective side panels 305 on the side of the first limiting plate 301a facing away from the second limiting plate 301b.

[0092] Alternatively, please refer to Figures 11 and 12. Figure 11 is an exploded view of a portion of the structure of another display device provided in an embodiment of the present application, and Figure 12 is a schematic view of a portion of the structure of another display device provided in an embodiment of the present application. The hinge 300 may further include: a protective member 306 movably connected to the side of the support base 301 facing away from the flexible display panel 400. The protective member 306 can be used to cover at least a portion of the flip assembly and at least a portion of the torsion mechanism 304. The protective member 306 can be slidably connected to the main support assembly 100 and the rotation support assembly 200, respectively, and the protective member 306 can be configured to: move away from the support base 301 during the process of switching the display device from the unfolded state to the folded state; and move toward the support base 301 during the process of switching the display device from the folded state to the unfolded state. In this case, by providing a protective member on the back of the display device, the protective member can protect the components between the protective member and the support base and can also provide a certain decorative effect on the back of the display device. In addition, please refer to Figure 13, which is a schematic diagram of the effect of switching between the unfolded state and the folded state of a display device provided in an embodiment of the present application. In order to prevent the main support assembly 100 and the rotating support assembly 200 from interfering with the protective member 306 during the bending process of the display device, the protective member 306 is slidably connected to the main support assembly 100 and the rotating support assembly 200, respectively, so that when the main support assembly 100 and the rotating support assembly 200 rotate relative to the support base 301, the protective member 306 can be driven to move in a direction away from the support base 301, thereby ensuring normal bending of the display device.

[0093] In an embodiment of the present application, please refer to Figure 14, which is a structural schematic diagram of a protective member provided in an embodiment of the present application. The target support assembly may include: a support portion and a second connecting block, the second connecting block may be fixedly connected to the side of the support portion facing away from the flexible display panel, and the side of the second connecting block has a second arc-shaped groove. The protective member 306 may include: a protective plate 306a, an extension portion 306b fixed to the side of the protective plate 306a facing the support seat 301, and a rotating plate 306c fixedly connected to the side of the extension portion 306b facing away from the protective plate 306a, the rotating plate 306c may have a second protrusion c3 that cooperates with the second arc-shaped groove on the second connecting block, and the second protrusion c3 may be slidably connected to the second connecting block in the second arc-shaped groove. In this case, through the cooperation between the second protrusion c3 on the rotating plate 306c and the second arc-shaped groove on the second connecting block, during the bending process of the display device, the target support assembly uses the second arc-shaped groove to limit the second protrusion, causing the second protrusion c3 to slide from one end of the second arc-shaped groove to the other end of the second arc-shaped groove, thereby driving the movement of the protective member 306. It should be noted that the arc length of the second arc-shaped groove can be set according to the actual movement distance of the protective member.

[0094] In the present application, as shown in Figures 11 and 12, the main support assembly 100 may include: a first support portion 101 and a second connecting block B3. The second connecting block B3 may be fixedly connected to the side of the first support portion 101 facing away from the flexible display panel 400, and the side of the second connecting block B3 may have a second curved groove A3. The rotation support assembly 200 may include: a second support portion 201 and a second connecting block B4. The second connecting block B4 may be fixedly connected to the side of the second support portion 201 facing away from the flexible display panel 400, and the side of the second connecting block B4 may have a second curved groove A4. The number of rotating plates in the protective member 305 may be two, each of which is provided with a second protrusion. For example, taking the second connecting block B3 as an example, the second connecting block B3 may include: a second connecting block body B31, and a connecting plate B32 fixedly connected to the second connecting block body B31. The side of the connecting plate B32 may have a second arc-shaped chute A3, and the strength of the connecting plate B32 may be greater than the strength of the second connecting block body B31. In this case, by setting the second arc-shaped chute A3 on the connecting plate B32, the strength of the connecting plate B32 is greater, so that the second protrusion c3 has better stability when sliding in the second arc-shaped chute A3. And after the second arc-shaped chute A3 is processed on the connecting plate B32, the connecting plate B32 is fixed to the second connecting block body B31, which simplifies the preparation process of the second arc-shaped chute. It should be noted that the structure of the second connecting block B4 is the same as that of the second connecting block B3, and will not be repeated here.

[0095] In the present application, as shown in Figure 12, the target support assembly may include: two second connecting blocks, the rotating plate may be distributed between the two second connecting blocks, and the rotating plate may have two second protrusions arranged opposite to each other. The two second protrusions may be respectively located in the two second arc-shaped grooves in the two second connecting blocks. That is, the main support assembly and the rotation support assembly may each include two second connecting blocks arranged opposite to each other. In this case, by setting two second connecting blocks in the target support assembly, the rotating plate in the protective member may be distributed between the two second connecting blocks, and the two second protrusions on the two rotating plates may be respectively connected with the second arc-shaped grooves on the two second connecting blocks, thereby effectively increasing the connection stability between the protective member and the rotation support assembly as well as the main support assembly.

[0096] Optionally, please refer to Figure 15, which is a schematic structural diagram of a support base provided in an embodiment of the present application. The protective member 306 may also include: a first guide member 306d fixedly connected to the side of the extension portion 306b facing away from the protective plate 306a, and the support base 301 may have a second guide member 301c on the side facing the protective plate 306a. Among them, one of the first guide member 306d and the second guide member 301c may be a blind hole, and the other of the first guide member 306d and the second guide member 301c may extend into this blind hole and be able to slide in the blind hole. In the present application, the protective member 306 may also include: a first guide plate 306e fixedly connected to the end of the protective plate 306a, the first guide plate 306e and the protective plate 306a are arranged vertically, and the first guide plate 306e has a guide groove c4 on the side facing the support base 301. The support seat 301 may also have a second guide plate 301d, which may be located on the side of the first limiting plate 301a away from the second limiting plate 301b. A portion of the second guide plate 301d may be located in the guide groove c4 and slidably connected to the first guide plate 306e.

[0097] In the embodiment of the present application, please refer to Figures 16 and 17.

The plurality of light-emitting devices 403 may be electrically connected to the driving backplane 401. The rotation axis of the support base 301 in the hinge 300 when rotating relative to the main support assembly 100 (the rotation axis passes through the virtual center of the first arc-shaped chute A1) can be located within the side I of the flat layer 402 that is away from the drive back plate 401; the rotation axis of the rotation support assembly 200 when rotating relative to the support base 301 in the hinge 300 (the rotation axis passes through the virtual center of the first arc-shaped chute A2) can be located within the side I of the flat layer 302 that is away from the drive back plate 301. In this case, the rotation axis of the support base 301 in the hinge 300 when rotating relative to the main support assembly 100 is located within the side of the flat layer 402 that is away from the drive back plate 401, and the rotation axis of the rotation support assembly 200 when rotating relative to the support base 301 in the hinge 300 is located within the side of the flat layer 402 that is away from the drive back plate 401. In this way, when the display device switches between the unfolded state and the folded state, the misalignment of the flexible display panel 400 caused by the inner and outer diameters when the rotating support assembly and the hinge rotate is effectively avoided, thereby avoiding the generation of tensile / compressive stress on the flexible display panel 400, ensuring a good display effect of the flexible display panel 400. In this application, the driving backplane 401 may include: a flexible substrate 401a, and a plurality of driving circuits 401b located on a side of the flexible substrate 401a close to the flat layer 402, the driving circuits 401b being used to drive the light-emitting devices 403 to operate.

The bottom plate 1200 may be fixedly connected to the side of the middle frame facing away from the flexible display panel 400. The covering member 1300 may be located on the side of the flexible display panel 400 facing away from the middle frame, and the covering member 1300 may cover the non-display area of ​​the flexible display panel 400. The covering member 1300 may include: a first rigid frame 1301 corresponding to the main support assembly 100, a first flexible frame 1302 corresponding to the hinge 300, and a second rigid frame 1303 corresponding to the rotation support assembly 200. The covering member 1300 may be engaged with the middle frame.

[0100] For example, the base plate 1200 may include: a first base plate 1201 and a second base plate 1202. The first base plate 1201 may be fixedly connected to the side of the main support assembly 100 facing away from the flexible display panel 400, and the second base plate 1202 may be fixedly connected to the side of the rotation support assembly 200 facing away from the flexible display panel 400.

[0101] In summary, an embodiment of the present application provides a display device, which may include: a main support assembly, two rotation support assemblies, a hinge, and a flexible display panel. By setting a hinge between the main support assembly and the rotation support assembly in the display device, at least two flip assemblies in the hinge are distributed on both sides of the support base and connected to the support base, another flip assembly is rotationally connected to the main support assembly, and another flip assembly is rotationally connected to the rotation support assembly. When the display device switches between the unfolded state and the folded state, under the action of an external force, the hinge can rotate a certain angle relative to the main support assembly, and the rotation support assembly can also rotate a certain angle relative to the hinge. At this time, the flexible display panel can also be folded into different shapes under the driving action of the hinge and the rotation support assembly. In this way, the display device equipped with a flexible display panel in the present application has a variety of different folding forms, which makes the display device more flexible to use and improves the user experience.
