Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of display, and in particular, to a support structure and a display device. BACKGROUND

[0002] The application of the foldable display device in the field of display is more and more, and the user can fold the foldable display device according to the actual demand to adjust the screen size of the foldable display device. The foldable display device includes a flexible display panel and a support structure, and the support structure is used to support the flexible display panel.

[0003] In the related art, the support structure includes a rotating shaft, a chain, a support plate and two sliding connection mechanisms. The rotating shaft and the support plate are used to support the foldable display area of the flexible display panel. The two sliding connection mechanisms are respectively rotatably connected with the rotating shaft and located on both sides of the rotating shaft, and the sliding connection mechanisms are used to support the non-foldable display area of the flexible display panel. The middle part of the chain is connected with the rotating shaft, and the two ends of the chain are respectively connected with the two sliding connection mechanisms. The support plate is fixedly connected with the middle part of the chain. When the support structure is folded, the sliding connection mechanisms rotate around the rotating shaft to realize the folding of the support structure.

[0004] The rotating shaft, the chain and the support plate are stacked. In the case that the thickness of the rotating shaft and the thickness of the chain are constant, in order to reduce the thickness of the support structure, the support plate is usually designed to be relatively thin, which causes the support plate to be easily damaged and the support structure to be damaged.

DETAILED DESCRIPTION

[0067] In order to make the objects, technical solutions and advantages of the present disclosure clearer, the following further describes the embodiments of the present disclosure in detail with reference to the drawings.

[0068] Figure 1 is a structural schematic diagram of a foldable display device in an unfolded state according to an embodiment of the present disclosure. Referring to Figure 1 The foldable display device comprises a first planar display portion 1, a foldable display portion 2 and a second planar display portion 3 connected in sequence. Figure 1 In the unfolded state, the surface of the first planar display portion 1, the surface of the foldable display portion 2 and the surface of the second planar display portion 3 are in the same plane.

[0069] Figure 2 is a structural schematic diagram of a foldable display device in a folded state according to an embodiment of the present disclosure. Referring to Figure 2 In the folded state, the bottom surface of the first planar display portion 1 is opposite to the bottom surface of the second planar display portion 3 by folding the foldable display portion 2, so that the foldable display device is more portable. The surface of a display portion is a display surface, and the bottom surface of the display portion is opposite to the surface of the display portion.

[0070] The foldable display device comprises a flexible display panel and a support structure for providing support to the flexible display panel.

[0071] Figure 3 is a structural schematic diagram of a support structure according to an embodiment of the present disclosure. Referring to Figure 3 The support structure comprises a rotating shaft 10, a sliding connection mechanism 23 and at least two chains 40.

[0072] The two sliding connection mechanisms 23 are respectively rotatably connected to the rotating shaft 10 and located on the two sides of the rotating shaft 10, and the two sliding connection mechanisms 23 are respectively used for supporting the non-folding display area of the flexible display panel. The at least two chains 40 are arranged in the axial direction of the rotating shaft 10, the extension direction of the at least two chains 40 is perpendicular to the axial direction of the rotating shaft 10, the middle part of the at least two chains 40 is respectively connected to the rotating shaft 10, and the two ends of each chain 40 are respectively connected to the two sliding connection mechanisms 23.

[0073] It is worth mentioning that, in order to show the structure of the rotating shaft and the like, Figure 3 not all the structures of the support structure are shown in the drawings.

[0074] Figure 4 is a structural schematic diagram of a support structure according to an embodiment of the present disclosure. Referring to Figure 4In the axial direction of the rotating shaft 10, each first support assembly 50 is connected between two adjacent chains 40, and the surface of the first support assembly 50 and the surface of the chain 40 away from the surface of the rotating shaft 10 are used to support the bendable display area of the flexible display panel.

[0075] In the embodiments of the present disclosure, since the first support assembly 50 is located between two adjacent chains 40, the surface of the first support assembly 50 and the surface of the chain 40 together form a support surface to support the bendable display area of the flexible display panel. In the case that the thicknesses of the chain 40 and the rotating shaft 10 are constant, the upper part of the chain 40 does not need to be arranged with a support plate, and the thickness of the foldable support device can be reduced. Meanwhile, the first support assembly 50 is designed between two adjacent chains 40, and the mountable height of the first support assembly 50 is increased, and the thickness of the first support assembly 50 can be increased, thereby improving the support strength of the entire support structure and reducing the possibility of damage to the foldable support device.

[0076] In the embodiments of the present disclosure, the rotating shaft 10 extends along a first direction a. The first support assembly 50 extends along the first direction a.

[0077] Referring again to Figure 3 and Figure 4 , the two sliding connection mechanisms 23 include at least two rotating plates 20 and at least one pair of sliding plates 30.

[0078] In a second direction b, the at least two rotating plates 20 are respectively located on two sides of the rotating shaft 10 and are respectively rotationally connected with the rotating shaft 10, and the second direction b is perpendicular to the first direction a. Each pair of sliding plates 30 includes two sliding plates 30 arranged at intervals along the second direction b, and different pairs of sliding plates 30 are arranged at intervals along the first direction a. The at least two chains 40 extend along the second direction b, and the at least two chains 40 are arranged at intervals along the first direction a. The middle parts of the at least two chains 40 are respectively connected with the rotating shaft 10, and any one of the at least two chains 40 is located between the two sliding plates 30 of a pair of sliding plates 30 and is respectively connected with the two sliding plates 30 of the pair of sliding plates 30 at two ends. Among them, any one of the at least two rotating plates 20 is opposite to one of the sliding plates 30, and the sliding plate 30 is slidingly connected with the opposite rotating plate 20, and the sliding direction of the sliding plate 30 is perpendicular to the second direction b.

[0079] In the embodiments of the present disclosure, the side of the sliding plate 30 away from the rotating plate 20 is used to support the flexible display panel, thereby providing support for the flexible display panel and ensuring the shape of the flexible display panel. The two ends of the chain 40 are respectively connected with the sliding plate 30, and the chain 40 also provides support for the flexible display panel while the sliding plate 30 provides support for the flexible display panel. The first support assembly 50 is located between the two adjacent chains 40, and the first support assembly 50 can also provide support for the flexible display panel.

[0080] In the embodiments of the present disclosure, the rotating shaft 10 and the chain 40 are respectively opposite to the bendable display part 2, and the sliding plates 30 located on both sides of the rotating shaft 10 are respectively opposite to the first planar display part 1 and the second planar display part 3. When it is needed to bend the bendable display device, the first planar display part 1 and the second planar display part 3 of the bendable display device are bent, and under the action of the extrusion force, the rotating plate 20 rotates around the rotating shaft 10, and the sliding plate 30 also rotates. Since the center line of the rotating of the rotating plate 20 is the center line of the rotating shaft 10, and the center line of the rotating of the sliding plate 30 is the center line of the chain 40, the center lines of the two do not coincide, and when rotating, the sliding plate 30 slides with the rotating plate 20, thereby enabling the bendable display device to be converted from the unbent state to the bent state.

[0081] In combination with Figure 3 and Figure 4 , the support structure includes four chains 40 and three first support assemblies 50. The four chains 40 are arranged at intervals along the first direction a, and the three first support assemblies 50 are respectively located between the two adjacent chains 40 of the four chains 40, and the three first support assemblies 50 are respectively located between different two chains 40.

[0082] In the embodiments of the present disclosure, the four chains 40 are arranged, and the rotation of the plurality of chains 40 drives the rotation of the sliding plate 30, so that the sliding plate 30 is more easily rotated. Meanwhile, the first support assembly 50 is arranged between any two adjacent chains 40, so as to ensure that the support surface formed by the chain 40 and the first support assembly 50 is more complete, and the support surface is larger, thereby improving the support performance of the support structure.

[0083] In other implementations, other numbers of chains 40 can be arranged, for example, two chains 40, three chains 40, five chains 40 or more chains, and the present disclosure does not limit this.

[0084] Again referring to Figure 4The four chains 40 include a first chain 41, a second chain 42, a third chain 43 and a fourth chain 44 arranged along the first direction a. The distance L1 between the first chain 41 and the second chain 42 is equal to the distance L2 between the third chain 43 and the fourth chain 44, and is less than the distance L3 between the second chain 42 and the third chain 43. That is, the length of the first support assembly 50 between the first chain 41 and the second chain 42 is equal to the length of the first support assembly 50 between the third chain 43 and the fourth chain 44, and is less than the length of the first support assembly 50 between the second chain 42 and the third chain 43. The length of the first support assembly 50 is the size of the first support assembly 50 in the first direction a.

[0085] In other implementations, the distance L1 between the first chain 41 and the second chain 42, the distance L2 between the third chain 43 and the fourth chain 44, and the distance L3 between the second chain 42 and the third chain 43 are equal. Alternatively, L1, L2 and L3 are all not equal.

[0086] In the embodiments of the present disclosure, the rotating shaft 10 can include four sub-rotating shafts (not shown in the figure) arranged along the first direction. The first chain 41, the second chain 42, the third chain 43 and the fourth chain 44 are respectively connected to different sub-rotating shafts.

[0087] For reference Figure 3 and Figure 4 The support structure includes four rotating plates 20 and a pair of sliding plates 30. Two of the four rotating plates 20 are located at one end of the rotating shaft 10 and are respectively located on both sides of the rotating shaft 10. The other two of the four rotating plates 20 are located at the other end of the rotating shaft 10 and are respectively located on both sides of the rotating shaft 10. One of the pair of sliding plates 30 is connected to one end of each of the four chains 40, and the other of the pair of sliding plates 30 is connected to the other end of each of the four chains 40.

[0088] In the embodiments of the present disclosure, the pair of sliding plates 30 are arranged. One sliding plate 30 includes two sliding parts and an intermediate elongated connecting part, and the two sliding parts are connected to the connecting part. Thus, the sliding plate 30 located on one side of the rotating shaft 10 is a whole piece, and there is also a part of the sliding plate 30 between the second chain 42 and the third chain 43. The part of the sliding plate 30 can support the flexible display panel, thereby improving the support performance of the support structure. The rotating plate 20 is located below the sliding plate 30, and has little effect on the support performance of the support structure. The four rotating plates 20 are arranged, and there is no rotating plate 20 between the second chain 42 and the third chain 43, which can reduce the overall weight of the rotating plate 20 and facilitate the lightweight design of the support structure.

[0089] In other implementations, other numbers of rotating plates 20 and sliding plates 30 may be arranged, for example, two rotating plates 20 and four sliding plates 30 may be arranged (the sliding plate 30 located on one side of the rotating shaft 10 is not a single piece at this time), and this disclosure does not limit this.

[0090] Figure 5 This is a schematic diagram of a support structure provided in this disclosure when it is in a bent state. See also... Figure 5 When the support structure bends, the first support component 50 will bend along with the chains (41, 42, 43, 44) to ensure the bending performance of the support structure.

[0091] Figure 6 This is an assembly diagram of a first support component, chain, and sliding plate provided in an embodiment of this disclosure. See also... Figure 6 The first support assembly 50 includes a plurality of first support members 501 arranged side by side along the second direction b. Any two adjacent first support members 501 are rotatably connected, and the rotation center line is parallel to the first direction a. Along the third direction c, the chain 40 and the first support members 501 are located on the same side of the rotating shaft 10, and the first direction a, the second direction b, and the third direction c are mutually perpendicular.

[0092] In this embodiment of the disclosure, the first support component 50 is bent by rotating between two adjacent first support members 501, thereby achieving the bending of the first support component 50.

[0093] Figure 7 yes Figure 6 The diagram shows the supporting structure in a bent state. (See attached diagram.) Figure 6 and Figure 7 The first support component 50 includes a plurality of first support members 501.

[0094] See you again Figure 6 In any two adjacent first support members 501 of the plurality of first support members 501, one of the first support members 501 has a first groove 502 on the outer side wall facing the other first support member 501, and the other first support member 501 has a first protrusion 503 fitted in the first groove 502, and the first protrusion 503 is rotatably connected to the first groove 502.

[0095] In this embodiment of the present disclosure, a first groove 502 is arranged on one of the first support members 501, and a first protrusion 503 is arranged on an adjacent first support member 501. The first protrusion 503 is rotatably connected to the first groove 502. Thus, when the first support assembly 50 is bent, the first protrusion 503 rotates in the first groove 502, thereby realizing the bending of the first support assembly 50.

[0096] Figure 8is a structural schematic diagram of a chain provided by an embodiment of the present disclosure. Referring to Figure 8 The support structure further comprises a first connecting pin 60, a middle portion of the first connecting pin 60 is fixedly connected with the chain 40, and one end of the first connecting pin 60 is fixedly connected with an end portion of the first support 501. Among them Figure 7 In order to clearly show the first connecting pin 60, part of the first support 501 is not shown.

[0097] In the embodiment of the present disclosure, the middle portion of the first connecting pin 60 is connected with the chain 40, and the two ends of the first connecting pin 60 are respectively connected with the end portions of the two first supports 501, so that the chain 40 and the first support 501 can be connected, and the first support 501 can be driven to rotate when the chain 40 rotates.

[0098] In the embodiment of the present disclosure, the end portion of the first support 501 can be a tubular structure, the first connecting pin 60 is inserted into the cavity of the tubular structure, and the first connecting pin 60 is in interference fit with the tubular structure, so that the first support 501 and the first connecting pin 60 do not need to be connected through other components, and the structure is simpler.

[0099] Referring again to Figure 7 The middle portion of the first support 501 located in the middle of the plurality of first supports 501 has a mounting groove 5011, and the flexible display panel has a mounting protrusion corresponding to the mounting groove 5011, when the support structure is mounted with the flexible display panel, the mounting protrusion is located in the mounting groove 5011 to realize alignment.

[0100] Exemplarily, the mounting groove 5011 is a rectangular mounting groove.

[0101] Exemplarily, the mounting protrusion is a steel protrusion, for example, a stainless steel (SUS) structure in the panel.

[0102] Referring again to Figure 7 The support structure further comprises two second support assemblies 70. Along the first direction a, the at least two chains 40 are located between the two second support assemblies 70, a side surface of one of the two second support assemblies 70 is connected with a side surface of one of the at least two chains 40 close to one end of the rotating shaft 10, and one end of the other of the two second support assemblies 70 is connected with a side surface of one of the at least two chains 40 close to the other end of the rotating shaft 10, the side surface of the chain 40 is a surface of the chain 40 facing the end portion of the rotating shaft 10 close to.

[0103] In the embodiment of the present disclosure, the second support assembly 70 is arranged at the end portion, and the second support assembly 70 can also form a support surface to support the flexible display panel, thereby improving the support performance of the support structure.

[0104] Referring again to Figure 6 , the second support assembly 70 includes two pairs of support pieces 701, the two pairs of support pieces 701 are arranged in the second direction b, each of the two pairs of support pieces 701 includes two second support pieces 702 arranged side by side in the second direction b, one end of the two second support pieces 702 is connected with the side of the chain 40 respectively. The outer side wall of the two second support pieces 702 has a second protrusion 703, and the side wall of the two second support pieces 702 with the second protrusion 703 is opposite, and the second protrusion 703 of the two second support pieces 702 is rotationally connected.

[0105] In the embodiment of the present disclosure, the two second support pieces 702 in each pair of support pieces 701 are rotationally connected through the second protrusion 703, when the chain 40 rotates, the second support piece 702 can be driven to rotate, thereby realizing the folding of the support structure.

[0106] Referring again to Figure 6 , the two ends of the first connecting pin 60 connected with the fourth chain 44 are connected with the first support assembly 50 and the second support piece 702 respectively, that is, the fourth chain 44 is connected with the first support assembly 50 and the second support piece 702 through the first connecting pin 60.

[0107] Similarly, the first chain 41 is also connected with the first support assembly 50 and the second support piece 702 through the first connecting pin 60.

[0108] Exemplarily, the second support piece 702 and the second protrusion 703 both have a through hole (not shown in the figure), the first connecting pin 60 is in interference fit with the through hole, realizing the connection of the first connecting pin 60 and the second support piece 702.

[0109] As shown in Figure 6 and Figure 7 , the support structure further includes a second connecting pin 1705, the second connecting pin 1705 is connected with the middle part of the chain 40 (for example, the fourth chain 44). The end of the second connecting pin 1705 is arranged with a circlip 180. Avoiding the second connecting pin 1705 from sliding out of the chain 40.

[0110] Referring again to Figure 8 , the chain 40 includes a first chain link 401 and a plurality of second chain links 402. One end of the first chain link 401 is connected with one of the pair of sliding plates 30. The plurality of second chain links 402 are rotationally connected in sequence, the second chain link 402 at one end of the plurality of second chain links 402 is rotationally connected with the other end of the first chain link 401, and the second chain link 402 at the other end of the plurality of second chain links 402 is connected with the other of the pair of sliding plates 30.

[0111] In this embodiment of the disclosure, the chain 40 is divided into multiple links to facilitate the rotation of the chain 40.

[0112] like Figure 8 As shown, one end of the first link 401 is connected to the middle of the first connecting pin 60, thus forming a connection. Figure 8 and Figure 7 One end of the first link 401 is connected to the sliding plate 30 via a first connecting pin 60. The first link 401 and the second link 402 are also connected via a first connecting pin 60, with the middle second link 402 connected via a second connecting pin 1705. Figure 8 (Not shown) is connected to the adjacent second link 402, and the remaining second links 402 are connected via the first connecting pin 60. (Combination) Figure 8 and Figure 7 The second link 402 at the second end is also connected to the sliding plate 30 via the first connecting pin 60. That is, the first connecting pin 60 at both ends connects the chain 40, the sliding plate 30, and the first support member 501.

[0113] like Figure 8 As shown, a chain 40 includes a first link 401 and five second links 402, that is, the chain 40 includes a total of six links. A chain 40 is connected to six first connecting pins 60. Since the chain 40 is connected to the first support component 50 through the first connecting pins 60, a first support component 50 also includes six first support members 501.

[0114] In other implementations, a chain 40 may include a different number of links. Similarly, the number of first connecting pins 60 and first support components 50 can be adjusted according to the number of links.

[0115] Figure 9 This is a schematic diagram of the structure of a first link provided in an embodiment of this disclosure. See also... Figure 9 The first link 401 is in the shape of an "I". One end of the "I"-shaped first link 401 has two first through holes 407. The first connecting pin 60 passes through the first through holes 407 to connect the first link 401 to the sliding plate 30 and the first support member 501. The other end of the "I"-shaped first link 401 also has two first through holes 407.

[0116] Figure 10 This is a schematic diagram of the structure of a second link provided in an embodiment of this disclosure. See also... Figure 10The other end of the second link 402 has a protrusion 409 matching the groove 408 of the other end of the first link 401. The protrusion 409 is located in the groove 408, and the protrusion 409 also has a second through hole 4010. The first support 501 passes through one first through hole 407 on the first link 401, the second through hole 4010 on the second link 402, and another first through hole 407 on the first link 401 in sequence, so as to connect the first link 401 and the second link 402.

[0117] Referring to body 8 and Figure 9 The first link 401 has a first limiting surface 403 and a second limiting surface 404. Referring to body 8 and Figure 10 The second link 402 also has a first limiting surface 403 and a second limiting surface 404. The second link 402 also has a third limiting surface 405 and a fourth limiting surface 406.

[0118] Referring to Figure 8 When the chain 40 is not bent, the first limiting surface 403 is attached to the third limiting surface 405. In this way, the flatness of the surface of the chain 40 can be ensured.

[0119] Figure 11 is a structural diagram of a chain bending provided by an embodiment of the present disclosure. Referring to Figure 11 When the chain 40 is in the maximum bending state, the second limiting surface 404 is attached to the fourth limiting surface 406. In this way, the chain cannot be bent any more, and the situation of over-bending or reverse-bending of the chain is avoided.

[0120] Figure 12 is a bottom view of a support structure provided by an embodiment of the present disclosure. Referring to Figure 12 The support structure has two rotating shafts 10 arranged side by side along the second direction b. Two rotating plates 20 located on both sides of the two rotating shafts 10 are connected with the two rotating shafts respectively.

[0121] Referring to Figure 12 The bending support structure also includes a lifting assembly 170. Referring to Figure 4 One end of the lifting assembly 170 is connected with the middle part of the chain 40, and the other end of the lifting assembly 170 is connected with the rotating shaft 10. The lifting assembly 170 is used to change the distance between the middle part of the chain 40 and the rotating shaft 10.

[0122] In the embodiment of the present disclosure, the lifting assembly 170 is used to connect the rotating shaft 10 and the chain 40, so as to ensure the stability of the chain 40. Since one end of the lifting assembly 170 is connected with the middle part of the chain 40, the bending of the chain 40 at the middle part can be ensured. The lifting assembly 170 can change the distance between the middle part of the chain 40 and the rotating shaft 10, so that more labor can be saved when bending.

[0123] Figure 13 is a structural schematic diagram of a lifting assembly provided by an embodiment of the present disclosure. Referring to Figure 13 The lifting assembly 170 comprises a first connecting block 1701, a second connecting block 1703, and an elastic sheet 1706. The second connecting block 1703 is in sliding connection with the first connecting block 1701. The first connecting block 1701 has a second shaft through hole 1702, and the middle part of the shaft 10 is located in the second shaft through hole 1702. The second connecting block 1703 has a connecting pin through hole 1704. One end of the elastic sheet 1706 is connected with the first connecting block 1701, and the other end of the elastic sheet 1706 is connected with the second connecting block 1703. In combination with Figure 4 One end of the second connecting pin 1705 is connected with the middle part of the chain 40, and the other end of the second connecting pin 1705 is connected with the connecting pin through hole 1704.

[0124] In the embodiment of the present disclosure, since the second connecting block 1703 is in sliding connection with the first connecting block 1701, the elastic sheet 1706 has elasticity, and the sliding of the second connecting block 1703 in the first connecting block 1701 is controlled by the elastic force of the elastic sheet 1706. The distance between the second shaft through hole 1702 and the connecting pin through hole 1704 can be changed, so that the distance between the middle part of the chain 40 and the shaft 10 can be changed.

[0125] Figure 13 The elastic sheet 1706 in the lifting assembly shown is in a compressed state. Figure 14 is a structural schematic diagram of a lifting assembly in another state provided by an embodiment of the present disclosure. In the process of rotation of the support structure, the distance between the middle part of the chain 40 and the shaft 10 will change. The lifting assembly 170 is used to control the distance between the middle part of the chain 40 and the shaft 10. When the support structure is in a planar state, the distance between the middle part of the chain 40 and the shaft 10 becomes short. At this time, the elastic sheet 1706 is compressed, so that the distance between the second connecting block 1703 and the first connecting block 1701 is reduced, thereby making the distance between the middle part of the chain 40 and the shaft 10 become short. When the support structure is in a bent state, the distance between the middle part of the chain 40 and the shaft 10 becomes long. The elastic force provided by the elastic sheet 1706 can make the distance between the second connecting block 1703 and the first connecting block 1701 increase, thereby making the distance between the middle part of the chain 40 and the shaft 10 become long.

[0126] Exemplarily, the first connecting block 1701 and the second connecting block 1703 are both block-shaped structures, and the elastic sheet 1706 is a sheet-shaped structure similar to a "W" shape.

[0127] In other implementations, the elastic sheet 1706 can also be composed of two end sheet-shaped structures and a middle elastic connecting part. The two end sheet-shaped structures are respectively used for connection and limiting, and the middle elastic connecting part is used for providing elastic force.

[0128] In other implementations, the lifting assembly can further not include the elastic sheet, and the lifting function of the lifting assembly can be realized only by the assembly relationship between the first connecting block and the second connecting block.

[0129] Figure 15 is an assembly diagram of the first connecting block and the second connecting block provided by an embodiment of the present disclosure. Referring to Figure 15 , the first connecting block 1701 has a convex through hole 1707 for mounting the second connecting block 1703, one end of the second connecting block 1703 is located in the convex through hole 1707, the other end of the second connecting block 1703 is located outside the convex through hole 1707, and the other end of the second connecting block 1703 has a limiting protrusion 1709 for limiting the other end of the second connecting block 1703 from being pulled out of the convex through hole 1707. The first connecting block 1701 and the second connecting block 1703 both have square through holes 1708. Referring to Figure 13 and Figure 14 The two ends of the elastic sheet 1706 are respectively located in the two square through holes 1708.

[0130] Figure 16 is a partial schematic view of a support structure provided by an embodiment of the present disclosure. Referring to Figure 16 , the support structure further includes a limiting assembly 80.

[0131] Figure 17 is a partial schematic view of a support structure provided by an embodiment of the present disclosure. Referring to Figure 18 , one end of the limiting assembly 80 abuts against the side surface of at least one rotating plate 20 of the at least two rotating plates 20, and the middle part of the limiting assembly 80 is fixedly connected with the rotating shaft 10. The end face of the other end of the limiting assembly 80 has a plurality of first limiting protrusions 801, the plurality of first limiting protrusions 801 are arranged in a circumferential interval, and a first limiting groove 802 is formed between adjacent two first limiting protrusions 801. The side surface of the rotating plate 20 abutting against the other end of the limiting assembly 80 has a plurality of second limiting protrusions 201, the plurality of second limiting protrusions 201 are arranged in a circumferential interval, a second limiting groove 202 is formed between adjacent two second limiting protrusions 201, and the center line of the rotating shaft 10 connected with the rotating plate 20 is on the same straight line as the center line of the circumference where the plurality of second limiting protrusions 201 are located. The first limiting protrusion 801 is located in the second limiting groove 202, the second limiting protrusion 201 is located in the first limiting groove 802, or the first limiting protrusion 801 abuts against the second limiting protrusion 201. Wherein, the limiting assembly 80 is located between the two sliding plates 30 of a pair of sliding plates 30.

[0132] Referring to Figure 17The limiting assembly 80 comprises a first stop block 803, a second stop block 804, an elastic member 805, and a mounting block 806. The first limiting protrusion 801 is located on an end surface of the first stop block 803 facing the rotating plate 20. The second stop block 804 is spaced apart from the first stop block 803 in the first direction. One end of the elastic member 805 is connected to the other end surface of the first stop block 803, and the other end of the elastic member 805 is connected to an end surface of the second stop block 804. The mounting block 806 is connected to the other end surface of the second stop block 804, and the mounting block 806 is fixedly connected to the rotating shaft 10.

[0133] Figure 18 is another partial view of the support structure provided by the embodiment of the present disclosure. Figure 18 and Figure 17 The main difference lies in the shape of the second stop block 804. In Figure 17 , the second stop block 804 is a columnar structure formed by stacking a plurality of rectangular corner pieces, and in Figure 18 , the second stop block 804 is a convex structure.

[0134] The support structure of Figure 18 is taken as an example for description. A limiting assembly 80 is added to the support structure. When the support structure is in different bending states, the limiting assembly 80 is used for limiting, so that the support structure is kept in a specific state, such as fully open, fully closed, half open, etc.

[0135] In Figure 18 , the support structure is in a fully closed state. At this time, the first limiting protrusion 801 is located in the second limiting groove 202, and the second limiting protrusion 201 is located in the first limiting groove 802.

[0136] Figure 19 is a partial view of a support structure provided by an embodiment of the present disclosure. Referring to Figure 19 , the support structure is in a fully open state. When the support structure is bent, the rotating plate 20 rotates, and the second limiting protrusion 201 on the rotating plate 20 rotates with the rotating plate 20. The second limiting protrusion 201 needs to overcome the resistance between the first limiting protrusion 801 and the second limiting protrusion 201, so that the first limiting protrusion 801 abuts against the second limiting protrusion 201, or the relative position of the second limiting protrusion 201 and the first limiting groove 802 changes, and the second limiting protrusion 201 is located in another first limiting groove 802, so that the support structure is kept in a specific state.

[0137] Figure 20 is a structural view of a limiting assembly provided by an embodiment of the present disclosure. Referring to Figure 20 , the end of the rotating shaft 10 passes through the first stop block 803, the elastic member 805, and the second stop block 804 in sequence, and then the end of the rotating shaft 10 is fixedly connected with the mounting block 806.

[0138] It is worth mentioning that in the embodiments of the present disclosure, the rotating shaft 10 can be composed of multiple sub-rotating shafts which are disconnected with each other. For example, in the embodiment shown in Figure 16 , one sub-rotating shaft passes through the left chain 40, and another sub-rotating shaft passes through the right chain 40 and is connected to the limiting assembly 80.

[0139] In the embodiments of the present disclosure, the first resisting block 803 is used to mount the first limiting protrusion 801, and the elastic member 805 provides elastic force to the first limiting protrusion 801, so that the first limiting protrusion 801 extrudes the rotating plate 20, so that the rotating plate 20 needs to overcome this part of the elastic force to rotate when rotating, thereby ensuring that the support structure remains in a specific state. The mounting block 806 is used to fix the second resisting block 804, so as to ensure that the position of the second resisting block 804 does not change, so that the elastic member 805 can be compressed to generate elastic force on the first limiting protrusion 801.

[0140] In the embodiments of the present disclosure, the first resisting block 803 has two circles of first limiting protrusions 801, and the two circles of first limiting protrusions 801 correspond to the second limiting protrusions 201 on the two rotating plates 20 respectively. That is, one circle of first limiting protrusions 801 matches the second limiting protrusions 201 on one rotating plate 20.

[0141] In the embodiments of the present disclosure, the support structure realizes the fixation of the rotating plate 20 in the rotating process through the damping of the elastic member 805 in the limiting assembly 80, that is, the self-locking can be realized through the limiting assembly 80.

[0142] Exemplarily, the elastic member 805 is a spring, or the elastic member 805 is a rubber sleeve, etc.

[0143] In the embodiments of the present disclosure, the elastic member 805 between the first resisting block 803 and the second resisting block 804 can be one, two, three or more.

[0144] Again referring to Figure 20 , the limiting assembly 80 further includes a mounting through hole 808, which is used to realize the connection with other components.

[0145] In the implementation manner of the present disclosure, the mounting block 806 and the second resisting block 804 can be made by an integral molding manner, and of course other connection manners can also be adopted.

[0146] Again referring to Figure 3 , the support structure further includes a cladding assembly 90. The cladding assembly 90 extends along the first direction a.

[0147] Figure 21 is an assembly schematic view of a cladding assembly and a rotating shaft connecting block provided by the embodiments of the present disclosure. Referring to Figure 21The support structure further comprises a rotating shaft connecting block 100. The rotating shaft connecting block 100 is fixedly connected to the middle part of the cladding assembly 90, and the rotating shaft connecting block 100 has a first rotating shaft through hole 1001 for the rotating shaft 10 to pass through. Wherein, along the third direction c, the limiting assembly 80 is located between the first support assembly 50 and the cladding assembly 90, and the cladding assembly 90 is connected with the limiting assembly 80.

[0148] In the embodiments of the present disclosure, the cladding assembly 90 clads the two ends of the support structure, ensuring the aesthetics of the bendable display device. Meanwhile, the rotating shaft connecting block 100 is arranged, the rotating shaft connecting block 100 is connected with the cladding assembly 90, the rotating shaft 10 passes through the first rotating shaft through hole 1001 on the rotating shaft connecting block 100, thereby connecting the rotating shaft 10 and the cladding assembly 90, ensuring the stability of the cladding assembly 90,

[0149] Referring to 20 again, the cladding assembly 90 comprises: a middle cladding plate 901, two rotating cladding plates 902 and a fixed protrusion 903. The middle cladding plate 901 extends along the first direction a, and the rotating shaft connecting block 100 is connected with the surface of the middle cladding plate 901. The two rotating cladding plates 902 both extend along the first direction a, and along the second direction b, the two rotating cladding plates 902 are respectively located on the two sides of the middle cladding plate 901, and the two rotating cladding plates 902 are respectively rotatably connected with the middle cladding plate 901. The fixed protrusion 903 is connected with the surface of the middle cladding plate 901, and the rotating shaft connecting block 100 and the fixed protrusion 903 are connected with the same surface of the middle cladding plate 901.

Such an arrangement not only ensures that the cover assembly 90 and the limiting assembly 80 can be installed together, but also when disassembled, the fixing protrusion 903 can be directly taken out of the fixing groove 807, so that the cover assembly 90 and the limiting assembly 80 are separated, which is more convenient.

[0152] Exemplarily, the fixing groove 807 includes a first sub-fixing groove 8071 and a second sub-fixing groove 8072, and the fixing protrusion 903 has a first sub-fixing boss 9031 and a second sub-fixing boss 9032, the first sub-fixing boss 9031 is located in the first sub-fixing groove 8071, and the second sub-fixing boss 9032 is located in the second sub-fixing groove 8072.
