[0029] For clearer descriptions of the objectives, technical solutions, and advantages of the present disclosure, embodiments of the present disclosure are described in detail hereinafter with reference to the accompanying drawings. Referring to FIGS. 1 and 2, FIG. 1 is a schematic structural diagram of a display apparatus according to some embodiments of the present disclosure, and FIG. 2 is a partial schematic structural diagram of the display apparatus shown in FIG. 1. The display apparatus is any product with a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, and a navigator, or a device body in a wearable device. The display apparatus may include: a body support assembly 100, two rotatable support assemblies 200, a hinge 300, and a flexible display panel 400.

[0030] The two rotatable support assemblies 200 in the display apparatus may be disposed on two sides of the body support assembly 100 in a first direction f1.

[0031] The hinge 300 in the display apparatus may be disposed between the body support assembly 100 and the rotatable support assembly 200 in the first direction f1, i.e., there may be one hinge 300 disposed between each rotatable support assembly 200 and the body support assembly 100. The hinge 300 may include: a support base 301 and at least two flip assemblies 302, the support base 302 may extend along a second direction f2 (e.g., the first direction may be perpendicular to the second direction) intersected with the first direction f1. At least two flip assemblies 302 are oppositely disposed in the first direction f1 and are both connected to the support base 301, one of the at least two flip assemblies 302 may be connected to the body support assembly 100, and another of the at least two flip assemblies may be connected to the rotatable support assembly 200. Exemplarily, the hinge 300 may include four flip assemblies 302, wherein two of the flip assemblies 302 are disposed along the first direction f1 on one side of the support base 301 and are both connected to the support base 301 and the body support assembly 100, and the other two flip assemblies 302 are disposed on the other side of the support base 301 and are both connected to the support base 301 and the rotatable support assembly 100.

[0032] The rear surface of the flexible display panel 400 in the display apparatus may be fixedly connected to the body support assembly 100, the support base 301, and the rotatable support assemblies 200, respectively. It should be noted that the rear surface of the flexible display panel 400 is a surface opposite to the display side of the flexible display panel 400.

[0033] In the embodiments of the present disclosure, by providing the hinge 300 between the body support assembly 100 and the rotatable support assembly 200 in the display apparatus, at least two flip assemblies 302 in the hinge 300 are disposed on two sides of the support base 301 and connected to the support base 301, wherein one flip assembly 302 can be rotatably connected to the body support assembly 100, and another flip assembly 302 can be rotatably connected to the rotatable support assembly 200. When the display apparatus is switched between the unfolded state and the folded state, the hinge 300 can rotate at a certain angle relative to the body support assembly 100 under the action of an external force, and the rotatable support assembly 200 can also rotate at a certain angle relative to the hinge 300. In this case, the flexible display panel 400 can also be folded into different patterns under the drive of the hinge 300 and the rotatable support assembly 200, such that the display apparatus provided with the flexible display panel 400 in the present disclosure supports various different folding patterns, which improves the flexibility in use of the display apparatus, and improves user experience. Here, in the process of switching between the unfolded state and the folded state of the display apparatus, the angle at which the hinge 300 rotates relative to the body support assembly 100 and the angle at which the rotatable support assembly 200 rotates relative to the hinge 300 may both be acute angles.

[0034] Exemplarily, referring to FIG. 3, FIG. 3 is a schematic effect diagram of switching between an unfolded state and a folded device according to some embodiments of the present disclosure. When the display apparatus is in the unfolded state, the side, facing towards the flexible display panel 400, of the body support assembly 100, the side, facing towards the flexible display panel 400, of the support base 301 in the hinge 300, and the side, facing towards the flexible display panel 400, of the rotatable support assembly 200 may be flush. When the display apparatus is switched from the unfolded state to the folded state, the hinge 300 and the rotatable support assembly 200 disposed on one side of the body support assembly 100 are illustrated schematically as an example: the direction in which the hinge 300 is rotated relative to the body support assembly 100 by the flip assembly 302 may be in the same direction as the direction in which the rotatable support assembly 200 is rotated relative to the hinge 300 by the flip assembly 302. It should be noted that the basic structural composition and movement principle of the rotatable support assembly 200 and the hinge 300, which are disposed on opposite sides of the body support assembly 100, are the same, and can be referred to as described above, and will not be repeated herein.

[0035] In summary, the embodiments of the present disclosure provide a display apparatus that may include: a body support assembly, two rotatable support assemblies, a hinge, and a flexible display panel. By providing the hinge between the body support assembly and the rotatable support assembly in the display apparatus, at least two flip assemblies in the hinge are disposed on two sides of the support base and are connected to the support base, another flip assembly is rotatably connected to the body support assembly, and another flip assembly is rotatably connected to the rotatable support assembly. When the display apparatus is switched between the unfolded state and the folded state, the hinge can rotate at a certain angle relative to the body support assembly under the action of an external force, and the rotatable support assembly can also rotate at a certain angle relative to the hinge. In this case, the flexible display panel can also be folded into different patterns under the drive of the hinge and the rotatable support assembly, such that the display apparatus provided with the flexible display panel in the present disclosure supports various different folding patterns, which improves the flexibility in use of the display apparatus, and improves user experience.

[0036] Optionally, referring to FIGS. 4 and 5, FIG. 4 is a partial schematic structural diagram of a display apparatus according to some embodiments of the present disclosure, and FIG. 5 is a partial structural sectional view of a display apparatus. Each of the at least two flip assemblies 302 in the hinge 300 may include: a rotating arm. A first end of the rotating arm 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. The target support assembly may be the body support assembly 100 or the rotational support assembly 200. In the present disclosure, the flip assembly 302 connected to the body support assembly 100 may be a first flip assembly 302a, and the flip assembly 302 connected to the rotatable 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 the first flip assembly 302a may be fixedly connected to an end of the support base 301, and a second end of the first flip assembly 302a may be rotatably connected to the body support assembly 100. The second flip assembly 302b may include a second turning arm 2b, a first end of the second turning arm 2b may be fixedly connected to the other end of the support base 301, and a second end of the second turning arm 2b may be rotatably connected to the rotatable support assembly 200. In this case, the first rotating arm 2a and the second rotating arm 2b are provided at opposite ends of the support base 301, the first rotating arm 2a is rotatably connected to the body support assembly 100, and the second rotating arm 2b is rotatably connected to the rotatable support assembly 200. In this way, the relative rotation between the body support assembly and the hinge, and between the hinge and the rotatable support assembly, can be easily realized by the rotation connection between the rotating arm and the target support assembly.

[0037] In the embodiment of the present disclosure, as shown in FIGS. 4 and 5, the rotating arm in the flip assembly 302 may be an arc-shaped slide plate, a side, facing towards the support base 301, of the target support assembly may be provided with a first arc-shaped chute matched with the arc-shaped slide plate, and at least a portion of the arc-shaped slide plate may be disposed in and rotatably connected to the first arc-shaped chute.

Taking the first arc-shaped slide plate a1 and the first arc-shaped chute A1 in the body support assembly 100 as examples, when the first arc-shaped slide plate a1 slides in the arc-shaped chute A1, the support base 301 can rotate in two different directions relative to the body support assembly 100, so as to change the angle between the hinge 300 and the body support assembly 100, and to realize the folding or unfolding of the display apparatus.

[0038] Optionally, the target support assembly may include: a support portion and a first connection block. A side, close to the support base 301, of the support portion may be provided with a mounting groove, and the first connection block may be secured in the mounting groove. A side, facing towards the rotating arm, of the first connection block may be provided with the first arc-shaped chute, and a surface, facing towards the flexible display panel, of the first connection block may be flush with a surface, facing towards the flexible display panel, of the support portion. The strength of the first connection block is greater than the strength of the support portion. In this case, by providing a mounting groove in the support portion in the target support assembly, the first connection block can be secured in the mounting groove, and it is ensured that the surface, facing towards the flexible display panel, of the first connection block is flush with the surface, facing towards the flexible display panel, of the support portion, which results in a better flatness of the flexible display panel. In addition, the strength of the first connection block is greater than the strength of the support portion, and the first arc-shaped chute is provided on the first connection block, which can ensure that the first arc-shaped chute basically does not deform during the process of the arc-shaped slide plate sliding in cooperation with the first arc-shaped chute, and ensures that the support base has better-sliding stability with the target support assembly. Exemplarily, the first connection block may be a structure made of a steel material, and the support portion may be a structure made of an aluminum material, such that the connection stability can be ensured, and a lower weight of the whole machine can be ensured.

[0039] In the present disclosure, as shown in FIGS. 4 and 5, the body support assembly 100 may include: a first support portion 101 and a first connection block B1. A side, close to the support base 301, of the first support portion 101 may be provided with a first mounting groove c1, and the first connection block B1 may be secured in the first mounting groove c1. A side, facing towards the first rotating arm 2a, of the first connection block B1 may be provided with a first arc-shaped chute A1, and a surface, facing towards the flexible display panel 400, of the first connection block B1 may be flush with a surface, facing towards the flexible display panel 400, of the first support portion 101. The rotatable support assembly 200 may include: a second support portion 201 and a first connection block B2.

The first connection block may be provided with a second positioning member clamped with the first positioning member and a connection hole in communication with the through hole, the connection hole may be closer to the flexible display panel than the through hole to the flexible display panel. The target support assembly may further include: a fastener, an end of the fastener may be fastened to the connection hole on the first connection block upon passing through the through hole. In this case, the coordination of the first positioning member and the second positioning member can effectively ensure the installation accuracy of the first connection block in the mounting groove. Moreover, since 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 connection hole, the first connection block can be effectively prevented from generating an undesirable phenomenon of local warping while connecting the support portion and the first connection block through fewer fasteners. For example, the number of fasteners may be one, and the number of through holes on the support portion and the number of connection holes on the first connection block may be one, which in turn can play a better role in sealing the interior of the display apparatus. Exemplarily, one of the first positioning member and the second positioning member may be a positioning column and the other may be a positioning hole, and the embodiments of the present disclosure are schematically illustrated with the first positioning member being a positioning hole and the second positioning member being a positioning column.

Furthermore, referring to FIG. 13, FIG. 13 is a schematic effect diagram of switching between an unfolded state and a folded state of a display apparatus according to some embodiments of the present disclosure. To prevent the body support assembly 100 and the rotatable support assembly 200 from interfering with the movement of the protective member 306 during the bending of the display apparatus, the protective member 306 is slidably connected to the body support assembly 100 and the rotatable support assembly 200, respectively, such that when the body support assembly 100 and the rotatable support assembly 200 rotate relative to the support base 301, the protective member 306 can be driven to move along a direction away from the support base 301, ensuring normal bending of the display apparatus.

In this case, by setting the second arc-shaped chute A3 on the connection plate B32, the strength of the connection plate B32 is greater, such that the second protrusion portion c3 has better stability when sliding within the second arc-shaped chute A3. Moreover, the connection plate B32 is fixed to the second connection block body B31 after the second arc-shaped chute A3 is processed on the connection plate B32, simplifying the preparation process of the second arc-shaped chute.
