[0033] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0034] It should be noted that in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, elements defined by the statement "comprising..." do not exclude the presence of additional identical elements in the process, method, article or device comprising the said elements.

[0035] For a better understanding of the present application, on the one hand, the following combines Figures 1 to 13A detailed description is given according to the embodiments of the present application.

[0037] As Figures 1 to 3 shown, an embodiment of the present application provides a support component 100 for supporting a flexible display panel 6. The support component 100 includes a first reel 1, a flexible support plate 2, and a driving assembly 3. The first reel 1 is arranged to extend along a first direction X. The flexible support plate 2 is used to support the flexible display panel 6, and the flexible support plate 2 can be retracted and extended along a second direction Y on the first reel 1. The flexible support plate 2 includes a main body portion 21 and a driven structure assembly 22, and the driven structure assembly 22 includes a driven member 221. The driving assembly 3 is arranged on one side of the flexible support plate 2 in the exhibition direction of the first reel 1 in the second direction Y. The driving assembly 3 includes a driving member 31 coupled to the corresponding driven member 221. By controlling the driving member 31, the flexible support plate 2 can be hovered at a preset position through the coupling and cooperation of the driving member 31 and the driven structure member. The first direction X, the second direction Y, and the thickness direction Z of the flexible support plate 2 intersect pairwise.

[0038] The support component 100 provided by the embodiment of the present application includes a first reel 1, a flexible support plate 2, and a driving assembly 3. The first reel 1 is arranged to extend along a first direction X so that the first reel 1 has sufficient dimensions for accommodating the flexible support plate 2. The embodiment of the present application does not limit the number of the first reels 1. For example, the number of the first reels 1 includes one or more. Exemplarily, a plurality of first reels 1 can be arranged in sequence along the first direction X to increase the length of the flexible support plate 2 along the first direction X, and at the same time, the total weight of the first reel 1 can be reduced, thereby reducing the weight of the support component 100.

[0039] The flexible support plate 2 can be wound around the first reel 1 to achieve the storage of the flexible support plate 2, and the wound flexible support plate 2 can be unfolded to form a bearing area for supporting the flexible display panel 6. The embodiments of the present application do not limit the combined structure of the main body portion 21 and the driven structure assembly 22 in the flexible support plate 2. For example, the driven structure assembly 22 can be composed of a partial structure of the main body portion 21. Or, the driven structure assembly 22 can also be two separable or detachable parts from the main body portion 21 and are fixedly connected by various fixing methods. The embodiments of the present application do not limit the positional relationship between the main body portion 21 and the driven structure assembly 22 in the flexible support plate 2. For example, the driven structure assembly 22 is located on one or both sides of the main body portion 21 opposite in the thickness direction Z. And / or, the driven structure assembly 22 is located on one or both sides of the main body portion 21 opposite in the first direction X.

[0040] The main body portion 21 of the flexible support plate 2 can carry the flexible display panel 6, and the driven member 221 in the driven structure assembly 22 can be coupled and matched with the corresponding driving member 31 in the driving assembly 3. Exemplarily, the driven member 221 in the driven structure assembly 22 is located on one side close to the first reel 1 of the two sides of the main body portion 21 opposite in the thickness direction Z, and the corresponding driving member 31 is located on the side of the driven member 221 facing away from the main body portion 21 to achieve the coupling and matching between the driving member 31 and the driven member 221.

[0041] It should be noted that the coupling and matching between the driving member 31 and the driven member 221 refers to the cooperation between the driving member 31 and the driven member 221 through mechanical transmission therebetween. Exemplarily, the driving member 31 is a gear, and the driven member 221 is a rack, a serrated structure or other structures matching the gear. The driving member 31 and the driven member 221 can also be other mechanical transmission structures. On the premise of ensuring that the driving member 31 drives the driven member 221, it is also necessary to ensure that the driving member 31 can be clamped at any position in the driven member 221 to enable the flexible support plate 2 to be unfolded to any support area.

[0042] The embodiments of the present application do not limit the number and corresponding relationship between the driven member 221 and the driving member 31. Exemplarily, the driven member 221 and the driving member 31 are in a one-to-one correspondence relationship, or multiple driven members 221 correspond to one driving member 31, or multiple driving members 31 correspond to one driven member 221, as long as it can ensure that the driving member 31 provides sufficient driving force and limiting force to achieve the unfolding action, winding action, or hovering action in a preset area of the flexible support plate 2.

[0043] According to the support component 100 and the display device 200 provided by the present application, the flexible support plate 2 is wound around and unwound from the first reel 1, so as to realize the deployment and storage of the flexible display panel 6. The driven structure assembly 22 in the flexible support plate 2 includes a driven member 221. The driving assembly 3 is located on one side in the deployment direction of the flexible support plate 2. The driving assembly 3 includes a driving member 31. By controlling the coupled movement of the driving member 31 and the driven member 221, the flexible support plate 2 is suspended at a preset position, so as to deploy a flexible display panel 6 with a preset area to adapt to different application scenarios.

[0044] Figure 4 For Figure 1 Another schematic cross-sectional structure diagram taken along A-A in Figure 5 For Figure 4 An enlarged schematic structure diagram of Q in

[0045] As Figure 4 And Figure 5 As shown in and , in some optional embodiments of the present application, the flexible support plate 2 includes two first surfaces 23 facing away from each other along the thickness direction Z of itself. The driven structure assembly 22 includes a first driven member 2211. The first driven member 2211 is disposed on at least one of the two first surfaces 23, and the driving member 31 corresponding to the first driven member 2211 is disposed on the side of the first driven member 2211 facing away from the main body portion 21.

[0046] In some optional embodiments, one of the two first surfaces 23 facing away from each other along the thickness direction Z of the flexible support plate 2 is used to carry the flexible display panel 6. The first driven member 2211 can be disposed on the first surface 23 carrying the flexible display panel 6, or the first driven member 2211 can be disposed on the first surface 23 not carrying the flexible display panel 6, or the first driven member 2211 can be disposed on both of the two first surfaces 23. It can be understood that, taking the first driven member 2211 disposed on one first surface 23 as an example, the driving member 31 is disposed on the side of the first surface 23 facing away from the main body portion 21 to realize the coupled cooperation between the driving member 31 and the first driven member 2211. The two first surfaces 23 facing away from each other along the thickness direction Z of the flexible support plate 2 extend along the first direction X to have dimensions and spaces for disposing the first driven member 2211, reducing the possibility of interference between the first driven member 2211 and other components in the support component 100, and reducing the possibility of the coupled cooperation failure between the first driven member 2211 and the driving member 31 after being used for a period of time.

[0047] Figure 6 This is a top view structural schematic diagram of another support component provided by some embodiments of the present application. Figure 7 For Figure 6 An enlarged schematic structure diagram of R in

[0048] As Figure 6 AndFigure 7 As shown, in some alternative embodiments of the present application, the flexible support plate 2 includes two second surfaces 24 facing away from each other in the first direction X. The driven structure assembly 22 includes a second driven member 2212. The second driven member 2212 is disposed on at least one of the two second surfaces 24, and the driving member 31 corresponding to the second driven member 2212 is disposed on the side of the second driven member 2212 facing away from the main body portion 21.

[0049] The embodiments of the present application do not limit the number of the second driven members 2212. Exemplarily, the number of the second driven members 2212 includes one or more. For example, when the number of the second driven members 2212 is one, the second driven member 2212 can be disposed on one of the two second surfaces 24. When the number of the second driven members 2212 is multiple, the second driven members 2212 can be disposed on the two second surfaces 24, and the multiple second driven members 2212 located on one second surface 24 and the multiple second driven members 2212 located on the other second surface 24 can be disposed in one-to-one correspondence.

[0050] As some alternative embodiments, the two second surfaces 24 of the flexible support plate 2 facing away from each other in the first direction X do not carry the flexible display panel 6. The second driven member 2212 is disposed on the second surface 24. When the support assembly 100 is shaken by an external force during the unfolding process, the possibility of contact between the second driven member 2212 on the flexible support plate 2 and the flexible display panel 6 is reduced, and the possibility of scratching the flexible display panel 6 by the second driven member 2212 is lowered.

[0051] As Figure 7 As shown, in some alternative embodiments of the present application, the driving member 31 is a gear including a plurality of first teeth 311 spaced apart from each other, and the driven member 221 is a serrated surface including a plurality of second teeth 2213 spaced apart from each other. The gear and the serrated surface are meshed and connected through the first teeth 311 and the second teeth 2213.

[0052] As some alternative embodiments, the circumferential side of the gear structure included in the driving member 31 has a plurality of first teeth 311, and the gaps between adjacent two first teeth 311 are used to cooperate with the second teeth 2213.

[0053] In some alternative embodiments, the driving member 31 is a gear and the driven member 221 is a serrated surface. As the driving member 31 rotates, the second teeth 2213 on the driven member 221 are sequentially meshed with the first teeth 311 to realize the driving of the driven member 221 by the driving member 31. And when the driving member 31 drives the flexible support plate 2 to a preset area, the first teeth 311 will lock the movement of the second teeth 2213 to reduce the possibility that the support area of the flexible support plate 2 changes under the action of an external force.

[0054] Please continue to refer toFigure 5 , in some alternative embodiments of the present application, the thickness of the flexible support plate 2 is H, the follower 221 further includes a recess 2214 between adjacent second teeth 2213, and the distance by which the recess 2214 is recessed in the thickness direction Z of the flexible support member is D1, and H and D1 satisfy the relationship 0.3H ≤ D1 ≤ 0.5H.

[0055] It can be understood that the thickness of the flexible support plate 2 is the sum of the thickness of the main body portion 21 and the thickness of the follower structure assembly 22. If the recess depth of the recess 2214 between adjacent second teeth 2213 on the follower 221 is too deep, it will affect the support performance of the flexible support plate 2. If the recess depth of the recess 2214 between adjacent second teeth 2213 on the follower 221 is too shallow, it will affect the coupling fit between the follower 221 and the driving member 31. In the embodiments of the present application, the relationship between the recess depth of the recess 2214 and the thickness of the flexible support plate 2 is defined as 0.3H ≤ D1 ≤ 0.5H to balance the coupling fit between the driving member 31 and the follower 221 and the support performance of the flexible support plate 2.

[0056] Please refer to Figure 1 and Figure 5 , in some alternative embodiments of the present application, the dimension of the driving member 31 in the axial direction is D2, and H and D2 satisfy the relationship 10H ≤ D2 ≤ 30H.

[0057] In some alternative embodiments, the axial direction of the driving member 31 is parallel to the first direction X. The longer the dimension of the driving member 31 in the axial direction, the larger the space occupied by the driving member 31. The smaller the dimension of the driving member 31 in the axial direction, the smaller the coupling contact area between the first teeth 311 in the driving member 31 and the second teeth 2213 in the follower 221, and the lower the efficiency of the driving force provided by the driving member 31 being transmitted to the follower 221. In the embodiments of the present application, the relationship between the dimension of the axial direction of the driving member 31 and the thickness of the flexible support plate 2 is defined as 10H ≤ D2 ≤ 30H to balance the space occupied by the driving member 31 and the driving efficiency between the driving member 31 and the follower 221.

[0058] Figure 8 For Figure 1 Another schematic cross-sectional structure diagram of A - A in

[0059] Please refer to Figure 6 and Figure 8 , in some alternative embodiments of the present application, the support assembly 100 further includes a guiding assembly 4, which is disposed on one side of the exhibition direction of the flexible support plate 2 of the first reel 1 in the second direction Y, and the flexible support plate 2 can be slidably disposed along the second direction Y with the guiding assembly 4.

[0060] In some alternative embodiments, the extension length of the guiding assembly 4 along the second direction Y is greater than the unfolded length of the flexible support plate 2 along the second direction Y, so as to reduce the possibility that the flexible support plate 2 curls due to the lack of restriction of the guiding assembly 4 at the end of the flexible support plate 2.

[0061] In some alternative embodiments, the guiding assembly 4 is arranged to extend along the second direction Y, and the flexible support plate 2 can slide relative to the guiding assembly 4 along the extending direction of the guiding assembly 4, so as to restrict the unfolding direction of the flexible support plate 2.

[0062] Please continue to refer to Figure 6 , in some alternative embodiments of the present application, the guiding assembly 4 includes two guiding members 41 arranged oppositely along the first direction X, and two opposite sides of the flexible support plate 2 along the first direction X are respectively slidably arranged with the corresponding guiding members 41.

[0063] Optionally, the guiding member 41 can be an integral structure. Of course, the guiding member 41 can also be composed of a plurality of foldable components.

[0064] It can be understood that the relative sliding between the guiding member 41 and the flexible support plate 2 can be achieved through a slot-slider, a slot-hook or other sliding methods.

[0065] Guiding members 41 are arranged on both sides of the flexible support plate 2 along the first direction X, so as to improve the stability of the flexible support plate 2 during the unfolding and winding processes.

[0066] Figure 9 For Figure 6 a schematic cross-sectional structure diagram of B-B in

[0067] Please refer to Figure 6 , Figure 8 and Figure 9 , in some alternative embodiments of the present application, the support assembly 100 includes a first state S1, the guiding member 41 includes a guiding groove 411 arranged along its own length direction, and in the first state S1, two opposite sides of the flexible support plate 2 along the first direction X extend into the guiding groove 411.

[0068] The flexible support plate 2 in the support assembly 100 can realize two states of unfolding and winding. In the embodiments of the present application, the first state S1 is taken as an example where the flexible support plate 2 is in the unfolded state for illustration.

[0069] As some alternative embodiments, the guiding groove 411 on the guiding member 41 has an opening, and the opposite sides of the flexible support plate 2 along the first direction X can extend into the guiding groove 411 through the opening. Extending the opposite sides of the flexible support plate 2 along the first direction X into the guiding groove 411 can increase the sliding area between the flexible support plate 2 and the guiding member 41, thereby reducing the possibility of separation between the flexible support plate 2 and the guiding member 41 when the flexible support plate 2 switches from the retracted state to the deployed state or from the deployed state to the retracted state.

[0070] As Figure 9 shown, in some alternative embodiments of the present application, the guiding assembly 4 further includes a guiding block 42. In the first state S1, the guiding block 42 is clamped and connected to the opposite side edges of the flexible support plate 2 along the first direction X within the guiding groove 411.

[0071] The surfaces of the guiding block 42 in contact with the guiding groove 411 can slide relative to each other. Optionally, a lubricating medium is filled between the guiding block 42 and the guiding groove 411 to reduce the sliding resistance.

[0072] The embodiments of the present application do not limit the shape of the guiding block 42. Exemplarily, the shape of the guiding block 42 includes a sphere, a cuboid, or other shapes.

[0073] The embodiments of the present application do not limit the number of the guiding blocks 42. Exemplarily, a plurality of guiding blocks 42 can be provided on one of the opposite side edges of the flexible support plate 2 along the first direction X to improve the guiding effect of the guiding assembly 4.

[0074] The guiding block 42 is clamped and connected to the opposite side edges of the flexible support plate 2 along the first direction X. The guiding block 42 provides the guiding effect for the flexible support plate 2, reducing the possibility of wear of the flexible support plate 2 after long-term sliding between the flexible support plate 2 and the guiding groove 411.

[0075] It can be understood that taking the flexible support plate 2 in the deployed state in the first state S1 as an example, the guiding block 42 is located within the guiding groove 411. During the process of the flexible support plate 2 transitioning from the deployed state to the retracted state, the guiding block 42 and the flexible support plate 2 are retracted onto the first reel 1 from within the guiding groove 411 together.

[0076] Optionally, the guiding block 42 can be located on the first surface 23 on one side of the flexible support plate 2. Or the guiding block 42 can also clamp the two first surfaces 23 of the flexible support plate 2 simultaneously.

[0077] Figure 10 For Figure 6 another schematic cross-sectional structure diagram of B-B in

[0078] As Figure 10As shown, in some alternative embodiments of the present application, the guiding groove 411 includes a plurality of repulsive portions 4111. The repulsive portions 4111 are located within the guiding groove 411 along the extending direction of the guiding groove 411, and the plurality of repulsive portions 4111 are correspondingly arranged on two opposite side surfaces along the thickness direction Z of the guiding member 41. The guiding block 42 repels the repulsive portions 4111.

[0079] In some alternative embodiments, the material of the repulsive portions 4111 includes a magnetic material. Exemplarily, magnetic materials are attached to two opposite side surfaces along the thickness direction Z of the guiding member 41 within the guiding groove 411 to form the repulsive portions 4111. It can be understood that the guiding block 42 includes a magnetic material with the same magnetism as the repulsive portions 4111, so that the guiding block 42 can be suspended in the guiding groove 411, thereby reducing the sliding resistance between the guiding block 42 and the guiding groove 411.

[0080] In some alternative embodiments of the present application, the guiding groove 411 includes a rotating portion located within the guiding groove 411. The rotating portion is rotatably arranged with the guiding groove 411, and the guiding block 42 is coupled to the rotating portion.

[0081] In some alternative embodiments, a rotating portion can be provided on the surface opposite to the opening of the guiding groove 411. It can be understood that one side of the guiding block 42 facing the rotating portion has a serrated structure that cooperates with the rotating portion, so that when the guiding block 42 moves in the guiding groove 411, the rotating portion can engage and rotate with the guiding block 42. In some other alternative embodiments, rotating portions can be provided on both sides along the thickness direction Z of the guiding member 41 within the guiding groove 411.

[0082] Figure 11 It is a top - view structural schematic diagram of a support assembly provided in some embodiments of the present application in the second state.

[0083] Please refer to Figure 11 , in some alternative embodiments of the present application, the support assembly 100 further includes a storage member 5. The storage member 5 includes a storage space 51. The first reel 1 is located within the storage space 51, and the flexible support plate 2 can be stored within the storage space 51.

[0084] Figure 11 It is the storage state of the support assembly 100. The storage state of the support assembly 100 is described as the second state S2.

[0085] The present application does not limit the shape of the storage member 5. Exemplarily, the shape of the storage member 5 includes a cube, a cuboid, a sphere, or other structures.

[0086] It is understandable that an opening is provided on the storage member 5, and the flexible support plate 2 in the storage space 51 can be wound and unfolded through the opening. The storage member 5 can prevent the flexible support member in the second state S2 from being scratched by external objects.

[0087] As Figure 11 shown, in some alternative embodiments of the present application, one end of the guiding member 41 is rotatably connected to the storage member 5, and the guiding member 41 is rotatably wound and unwound from this end into the storage space 51.

[0088] In some alternative embodiments, one end of the guiding member 41 is rotatably connected to the storage member 5. For example, one end of the guiding member 41 is rotatably connected to a surface of the storage member 5 located outside. Or, one end of the guiding member 41 is rotatably connected to a surface within the storage space 51 of the storage member 5.

[0089] It is understandable that the guiding member 41 can rotate with this rotatably connected end as the rotation fulcrum and rotate into the storage space 51 in a preset rotation direction. For the convenience of storage, the guiding member 41 can be provided as being composed of multiple components. In the second state S2, these multiple components are nested with each other, thereby shortening the extended length of the guiding member 41.

[0090] On the other hand, an embodiment of the present application further provides a display device 200, including a flexible display panel 6 and a support assembly 100 as any one of the above. The support assembly 100 is used to support the flexible display panel 6.

[0091] Figure 12 It is a top view structural schematic diagram of a display device provided by some embodiments of the present application. Figure 13 For Figure 12 a cross-sectional structural schematic diagram of C-C in

[0092] As Figure 12 and Figure 13 shown, in some alternative embodiments of the present application, the display device 200 further includes a second reel 7. The second reel 7 is located on a side of the first reel 1 facing away from the driving assembly 3, and the flexible display panel 6 can be wound and unwound on the second reel 7 along the second direction Y.

[0093] Optionally, the second reel 7 is used to wind and unwind the flexible display panel 6. One end of the flexible display panel 6 can be fixedly connected to the second reel 7, thereby reducing the possibility that the flexible display panel 6 cannot be wound up after being unfolded.
