[0073] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0074] Unless otherwise defined, the technical terms or scientific terms used herein shall have the usual meanings understood by persons with ordinary skills in the field to which the present disclosure belongs. The words "first", "second", "third" and similar words used in the patent application specification and claims of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "one" do not indicate a quantity limitation, but indicate the existence of at least one. Words such as "include" or "comprise" and similar words mean that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, and do not exclude other elements or objects. Words such as "connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right", "top", "bottom" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0075] In the related art, there is a foldable display device, which includes a flexible display panel and a support assembly, and the support assembly is located on the non-display surface of the flexible display panel. The support assembly includes a first support plate, a second support plate, a third support plate, a first bending assembly and a second bending assembly. The first bending assembly includes a first body and at least one pair of first rotating arms, each pair of first rotating arms is rotatably connected to both sides of the first body, and is respectively connected to the first support plate and the second support plate. The second bending assembly includes a second body and at least one pair of second rotating arms, each pair of second rotating arms is rotatably connected to both sides of the second body, and is respectively connected to the second support plate and the third support plate. The support assembly is configured to be switchable between a folded state and an unfolded state. In the folded state, the second support plate, the first support plate and the third support plate are stacked in sequence, and in the unfolded state, the first support plate, the second support plate and the third support plate are located in the same plane.

[0076] However, in the process of switching from the unfolded state to the folded state, the first support plate and the third support plate are both bent toward the same side of the second support plate in the middle, and the first support plate is still between the second support plate and the third support plate in the folded state, and the display device is folded in a G shape. Since both the support plate and the flexible display panel have thickness, the G-shaped folding method may result in insufficient space between the second support plate and the third support plate to accommodate the flexible display panel in the folded state, thereby causing damage to the flexible display panel on the support assembly during the bending process, affecting the reliability of the display device.

[0077] To this end, an embodiment of the present disclosure provides a display device that can switch between a folded state and an unfolded state, and can reduce the probability of damage to the flexible display panel on the supporting assembly during the bending process, thereby improving the reliability of the display device.

[0078] Figure 1 is a schematic diagram of the structure of a display device provided by an embodiment of the present disclosure. Figure 1 As shown, the display device includes a flexible display panel 1 and a supporting component 2 , and the supporting component 2 is located on the non-display surface of the flexible display panel 1 .

[0079] Figure 2 Schematic diagram of a support assembly provided by an embodiment of the present disclosure. Figure 2 As shown, the support assembly 2 includes a first support plate 10, a second support plate 11, a third support plate 12, a first bending assembly 20 and a second bending assembly 30. The first bending assembly 20 includes a first body 21 and at least one pair of first rotating arms 22, each pair of first rotating arms 22 is rotatably connected to both sides of the first body 21, and is respectively connected to the first support plate 10 and the second support plate 11. The second bending assembly 30 includes a second body 31 and at least one pair of second rotating arms 32, each pair of second rotating arms 32 is rotatably connected to both sides of the second body 31, and is respectively connected to the second support plate 11 and the third support plate 12.

[0080] Figure 3 It is a schematic diagram of the structure of a display device in a folded state provided by an embodiment of the present disclosure. Figure 4 It is a schematic diagram of the partial structure of a display device in a folded state provided by an embodiment of the present disclosure. Figure 4 Part (a) of Figure 2 Schematic diagram of the local structure when the middle section line A1 is in the folded state. Figure 4 Part (b) of Figure 2 Schematic diagram of the local structure with the middle section line A2 in the folded state. Figures 1 to 4 , the support assembly 2 is configured to be switchable between a folded state and an unfolded state. In the folded state, the second support plate 11, the first support plate 10, and the third support plate 12 are stacked in sequence, and the minimum distance H1 between each pair of first rotating arms 22 is less than the minimum distance H2 between each pair of second rotating arms 32. In the unfolded state, the first support plate 10, the second support plate 11, and the third support plate 12 are located in the same plane. Here, the minimum distance H1 between each pair of first rotating arms 22 refers to the minimum value of the distance between each pair of first rotating arms 22, and the minimum distance H2 between each pair of second rotating arms 32 refers to the minimum value of the distance between each pair of second rotating arms 32.

[0081] In the disclosed embodiment, each pair of first rotating arms 22 is connected to the first support plate 10 and the second support plate 11, respectively, and each pair of second rotating arms 32 is connected to the second support plate 11 and the third support plate 12, respectively. In the folded state, the second support plate 11, the first support plate 10 and the third support plate 12 are stacked in sequence. That is, in the process of switching from the unfolded state to the folded state, the first support plate 10 and the third support plate 12 are bent to the same side of the second support plate 11, and the first support plate 10 is still present between the second support plate 11 and the third support plate 12 in the folded state, and the display device is folded in a G shape. In the folded state, the minimum distance H1 between each pair of first rotating arms 22 is less than the minimum distance H2 between each pair of second rotating arms 32, that is, compared with the space between the first support plate 10 and the second support plate 11, the space between the second support plate 11 and the third support plate 12 is larger. This helps to form a space sufficient to accommodate the flexible display panel 1 between the second support plate 11 and the third support plate 12 in the folded state, thereby reducing the probability of damage to the flexible display panel 1 on the support assembly 2 during the bending process and improving the reliability of the display device.

[0082] Figure 5 It is a schematic diagram of the partial structure of a display device in an unfolded state provided by an embodiment of the present disclosure. Figure 5 Part (a) of Figure 2 Schematic diagram of the local structure when the middle section line A1 is in the unfolded state. Figure 5 Part (b) of Figure 2 Schematic diagram of the local structure with the middle section line A2 in the unfolded state. Figure 1 , Figure 2 , Figure 4 and Figure 5 The first bending assembly 20 further includes at least one pair of first co-moving gears 23, each pair of first co-moving gears 23 meshes with each other, and each pair of first co-moving gears 23 is located between a pair of first rotating arms 22. The first rotating arm 22 includes a first rotating member 220, and the first rotating member 220 has a first rotating plate portion 2201 and a first gear portion 2202 connected to each other. The first gear portion 2202 meshes with the first co-moving gear 23, and the first rotating plate portion 2201 includes a bent plate, and in a direction perpendicular to the non-display surface, the minimum distance between the end of the bent plate away from the first gear portion 2202 and the non-display surface is less than the minimum distance between the end of the bent plate close to the first gear portion 2202 and the non-display surface. That is, it can be understood that the first rotating plate portion 2201 includes a flat plate with a bent middle section, and in a direction close to the first gear portion 2202, the flat plate is bent in a direction away from the non-display surface to form the bent plate.

[0083] The second bending assembly 30 further includes at least one pair of second co-moving gears 33, each pair of second co-moving gears 33 meshes with each other, and each pair of second co-moving gears 33 is located between a pair of second rotating arms 32. The second rotating arm 32 includes a second rotating member 320, and the second rotating member 320 has a second rotating plate portion 3201 and a second gear portion 3202 connected to each other. The second gear portion 3202 meshes with the second co-moving gear 33, and the second rotating plate portion 3201 includes a flat plate, which is parallel to the non-display surface.

[0084] Through the cooperation of the first rotating member 220 and the first co-moving gear 23, and the cooperation of the second rotating member 320 and the second co-moving gear 33, the rotation effect of the first rotating arm 22 and the second rotating arm 32 can be achieved, so that the support assembly 2 can be switched between the folded state and the unfolded state. The first rotating plate portion 2201 includes a bending plate, and in the direction perpendicular to the non-display surface, the minimum distance between the end of the bending plate away from the first gear portion 2202 and the non-display surface is less than the minimum distance between the end of the bending plate close to the first gear portion 2202 and the non-display surface. The second rotating plate portion 3201 includes a flat plate, which is parallel to the non-display surface, so that the minimum distance between each pair of first rotating arms 22 can be less than the minimum distance between each pair of second rotating arms 32 through the bending shape of the first rotating plate portion 2201, which is conducive to reducing the probability of damage to the flexible display panel 1 on the support assembly 2 during the bending process.

[0085] Exemplarily, the plane where the portion of the bending plate away from the first gear portion 2202 is located is parallel to the non-display surface, and the plane where the portion of the bending plate close to the first gear portion 2202 is located intersects with the non-display surface.

[0086] It should be noted that, in the embodiment of the present disclosure, the shapes of the first rotating plate portion 2201 and the second rotating plate portion 3201 are only used as an example. In other embodiments, the first rotating plate portion 2201 and the second rotating plate portion 3201 may also adopt other shapes, for example, the second rotating plate portion 3201 may also include a bending plate, etc., so long as the minimum distance between each pair of first rotating arms 22 in the folded state is smaller than the minimum distance between each pair of second rotating arms 32, and the present disclosure does not impose any limitation on this.

[0087] For example, the first rotating plate portion 2201 and the first gear portion 2202 of the first rotating member 220 may be an integrally formed structure. The second rotating plate portion 3201 and the second gear portion 3202 of the second rotating member 320 may be an integrally formed structure.

[0088] Exemplarily, the first gear portion 2202 has a plurality of teeth on one side close to the first co-moving gear 23 and close to the non-display surface, and the first gear portion 2202 is meshed with the first co-moving gear 23 through the plurality of teeth. The second gear portion 3202 has a plurality of teeth on one side close to the second co-moving gear 33 and close to the non-display surface, and the second gear portion 3202 is meshed with the second co-moving gear 33 through the plurality of teeth.

[0089] like Figure 5 As shown, the diameter D1 of the first co-moving gear 23 is smaller than the diameter D2 of the second co-moving gear 33. Through the differential setting of the diameters of the first co-moving gear 23 and the second co-moving gear 33, the minimum distance between each pair of second rotating arms 32 in the folded state can be effectively increased in cooperation with the bent plate and the straight plate, so that the minimum distance between each pair of first rotating arms 22 in the folded state is smaller than the minimum distance between each pair of second rotating arms 32.

The second bending assembly 30 further includes at least one second driving unit 34, which is fixed to the second body 31 and used to drive the at least one second rotating arm 32 to rotate. In this way, the first driving unit 24 and the second driving unit 34 facilitate the switching of the support assembly 2 between the folded state and the unfolded state, thereby improving the convenience and reliability of the state switching.

[0091] Exemplarily, the first body 21 includes a first shell having a first placement groove, and the second body 31 includes a second shell having a second placement groove.

[0093] Exemplarily, the first driving unit 24 is located in the first placement groove and fixed on the first shell, and the second driving unit 34 is located in the second placement groove and fixed on the second shell.

[0094] It should be noted that the configuration of the first drive unit 24 and the second drive unit 34 in the embodiment of the present disclosure is only an example. In other embodiments, the first drive unit 24 and the second drive unit 34 may also be configured in other ways, as long as they can realize the function of driving the first rotating arm 22 and the second rotating arm 32 to rotate, and the present disclosure does not limit this.

[0095] Figure 8 It is a schematic diagram of the partial structure of a display device in an unfolded state provided by an embodiment of the present disclosure. Figure 8 Part (a) of Figure 2 Schematic diagram of the local structure when the middle section line B1 is in the unfolded state. Figure 8 Part (b) of Figure 2 The schematic diagram of the local structure when the middle section line B2 is in the unfolded state. Figures 5 to 8 As shown, the first driving unit 24 includes a first motor 240 and a first transmission structure 241, and the output shaft of the first motor 240 is connected to a first co-moving gear 23 through the first transmission structure 241. The second driving unit 34 includes a second motor 340 and a second transmission structure 341, and the output shaft of the second motor 340 is connected to a second co-moving gear 33 through the second transmission structure 341.

[0098] Since the arrangement of the output shaft of the first motor 240 and the rotation axis of the first co-moving gear 23 is limited by the space of the first body 21, the arrangement of the output shaft of the second motor 340 and the rotation axis of the second co-moving gear 33 is limited by the space of the second body 31, and the diameter D1 of the first co-moving gear 23 is smaller than the diameter D2 of the second co-moving gear 33, the output shaft of the first motor 240 is more easily connected to the first co-moving gear 23, and the output shaft of the second motor 340 may be difficult to be connected to the second co-moving gear 33. The second transmission structure 341 is set as the first transmission gear 3411 and the second transmission gear 3412, which can better transmit the power, ensure the better control effect of the second motor 340, and is conducive to realizing that in the folded state, the second support plate 11, the first support plate 10 and the third support plate 12 are stacked in sequence, and the minimum distance between each pair of first rotating arms 22 is smaller than the minimum distance between each pair of second rotating arms 32.

Fig.13 Can be expressed Fig.11 Schematic diagram of the local structure when the middle section line E1 is in the unfolded state. Fig.14 It is a schematic diagram of the partial structure of a support assembly provided in an embodiment of the present disclosure. Fig.14 It can represent the local structure of the second bending component. Fig.15 It is a schematic diagram of the partial structure of a display device in an unfolded state provided by an embodiment of the present disclosure. Fig.15 Can be expressed Fig.11 The schematic diagram of the local structure when the middle section line E2 is in the unfolded state. Figures 11 to 15 As shown, the first torsion spring 242 includes a first torsion spring arm 2421, a second torsion spring arm 2422 and two first body parts 2423, the two first body parts 2423 are respectively sleeved on the two ends of the axial direction of the first gear part 2202, and the first body part 2423 is coaxially connected to the first gear part 2202, the first torsion spring arm 2421 is connected to the first rotating plate part 2201, and the second torsion spring arm 2422 is fixed to the first body 21. The second torsion spring 342 includes a third torsion spring arm 3421, a fourth torsion spring arm 3422 and two second body parts 3423, the two second body parts 3423 are respectively sleeved on the two ends of the axial direction of the second gear part 3202, and the second body part 3423 is coaxially connected to the second gear part 3202, the third torsion spring arm 3421 is connected to the second rotating plate part 3201, and the fourth torsion spring arm 3422 is fixed to the second body 31.

[0123] Fig.16 It is a structural schematic diagram of a support assembly provided in an embodiment of the present disclosure. Fig.16 It may refer to the structure of the side of the supporting component away from the flexible display panel. Fig.17 FIG. 1 is a partial structural diagram of a support assembly provided by an embodiment of the present disclosure. Figures 11 to 17As shown, the support assembly 2 also includes a first magnetic body 40, a second magnetic body 41 and a third magnetic body 42. The first magnetic body 40 is located on the surface of the first support plate 10 away from the flexible display panel, the second magnetic body 41 is located on the surface of the second support plate 11 away from the flexible display panel, and the third magnetic body 42 is located on the surface of the third support plate 12 away from the flexible display panel. In the folded state, the first magnetic body 40, the second magnetic body 41 and the third magnetic body 42 are used to provide a first locking force so that the display device can remain in the folded state, and the first locking force is greater than the sum of the first torsion provided by the first torsion spring 242 and the second torsion spring 342. Through the sum of the attractive forces between the first magnetic body 40, the second magnetic body 41 and the third magnetic body 42, that is, the magnetic attraction, the first locking force can be provided in the folded state so that the display device can remain in the folded state, and when an external force is applied so that the sum of the external force and the first torsion provided by the first torsion spring 242 and the second torsion spring 342 is greater than the first locking force, the display device can be switched to the unfolded state.

[0124] Fig.18 It is a schematic diagram of the structure of a display device in a folded state provided by an embodiment of the present disclosure. Fig.19 is a schematic diagram of the structure of a display device in a folded state provided by an embodiment of the present disclosure. Figures 11 to 19 The support assembly 2 further includes a switch assembly 50, which is connected to the first magnetic body 40. The switch assembly 50 is used to move the first magnetic body 40 from the first position to the second position under the action of an external force. When the first magnetic body 40 is located at the first position, the sum of the attractive forces between the first magnetic body 40, the second magnetic body 41 and the third magnetic body 42 in the folded state is the first locking force. When the first magnetic body 40 is located at the second position, the sum of the attractive forces between the first magnetic body 40, the second magnetic body 41 and the third magnetic body 42 in the folded state is less than the sum of the first torsion provided by the first torsion spring 242 and the second torsion spring 342. The movement of the first magnetic body 40 can be controlled by the switch assembly 50. Since the sum of the attractive forces between the first magnetic body 40, the second magnetic body 41 and the third magnetic body 42 is affected by the position, the magnitude of the attractive forces between the magnetic bodies can be changed, so that the sum of the first torsion provided by the first torsion spring 242 and the second torsion spring 342 is larger, so that the display device is switched between the folded state and the unfolded state through the switch assembly 50, which improves the convenience of operation.

[0125] Fig.18 The first magnetic body 40 is located at the first position, Fig.19 The first magnetic body 40 is located at the second position. Figures 11 to 19The switch assembly 50 includes a pressing member 51, a lever 52 and an elastic reset member 53. The first end of the lever 52 contacts the pressing member 51, the second end of the lever 52 is connected to the first magnetic body 40, and the middle part of the lever 52 is rotatably connected to the first support plate 10. The first end of the elastic reset member 53 is fixed to the first support plate 10, the second end of the elastic reset member 53 is connected to the first magnetic body 40, and the elastic reset member 53 is used to apply a reset force to the first magnetic body 40 when the first magnetic body 40 is in the second position, so that the first magnetic body 40 moves from the second position to the first position.

[0126] The elastic reset member 53 refers to a component that uses the elastic properties of the material to store and release energy. When an external force acts on the elastic reset member 53, the elastic reset member 53 will deform and store energy; when the external force disappears, the elastic reset member 53 will release the stored energy and automatically return to its original shape, thereby achieving the function of automatic reset.

[0127] The cooperation between the pressing member 51, the lever 52 and the elastic return member 53 can better control the movement of the first magnetic body 40. When the first magnetic body 40 is in the first position in the folded state, the sum of the attractive forces between the first magnetic body 40, the second magnetic body 41 and the third magnetic body 42 is large, equal to the first locking force, and greater than the sum of the first torques provided by the first torsion spring 242 and the second torsion spring 342, so that the display device can maintain the folded state. In the folded state, the first magnetic body 40 can be controlled to move to the second position by the pressing member 51 and the lever 52. The sum of the attractive forces between the first magnetic body 40, the second magnetic body 41 and the third magnetic body 42 is small, which is smaller than the sum of the first torsion provided by the first torsion spring 242 and the second torsion spring 342. Under the action of the first torsion spring 242 and the second torsion spring 342, the connected first rotating plate portion 2201 and the second rotating plate portion 3201 can be driven to rotate, thereby driving at least one pair of first rotating arms 22 on both sides of the first body 21 to rotate, and driving at least one pair of second rotating arms 23 on both sides of the second body 31 to rotate, so as to control the rotation of the first support plate 10, the second support plate 11, and the third support plate 12. In this way, the display device will switch to the unfolded state, and at this time, the elastic reset member 53 will deform and store energy. After the external force on the pressing member 51 stops being applied in the unfolded state, the elastic return member 53 releases the stored energy and automatically returns to the original shape. That is, the first magnetic body 40 can be moved back to the first position by the elastic return member 53, so that the display device can be manually switched to the folded state and the folded state can be kept unchanged.

[0128] Exemplarily, the sliding stroke of the first magnetic body 40 when moving from the first position to the second position is 5 mm.

[0129] Exemplarily, the lever 52 includes a first sub-rod 520, a second sub-rod 521, and a third sub-rod 522.
