[0028] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0029] See also Figure 1 and Figure 2 , Figure 1 This is a structural diagram of an embodiment of the support assembly of this application. Figure 2 for Figure 1Exploded schematic diagram of an embodiment of a support assembly. The support assembly 1 is used to support a flexible screen, which can be a flexible OLED screen or a flexible Micro-LED screen. The support assembly 1 includes a main body 10 and a first support member 12.
[0030] Specifically, the main body mechanism 10 includes a first surface 1000, and the first surface 1000 is used to support a portion of the flexible screen; optionally, the first surface 1000 is also used to fix the portion of the flexible screen by means of an adhesive or the like. At least part of the first support member 12 is located outside the main body mechanism 10 and is arranged in alignment with the main body mechanism 10 to support the flexible screen beyond the first surface 1000. The first support member 12 includes a first end 121 and a second end 123 arranged along the length direction, and the first end 121 and the second end 123 refer to two ends arranged opposite to each other in the length direction when the first support member 12 is fully unfolded. The first end 121 is fixed relative to the main body mechanism 10, and the second end 123 slides in a direction close to or away from the main body mechanism 10 to change the size of the support surface formed by the first support member 12 and the host mechanism 10; and in the sliding direction X, as Figure 7 As shown, in the sliding direction X, the first support member 12 includes a plurality of flexible members 120 arranged in parallel, and adjacent flexible members 120 are interconnected to form a mesh structure. This design can improve the flexibility of the first support member 12 in the sliding direction X. Preferably, the meshes in the formed mesh structure can be approximately quadrilateral, for example, a diamond shape.
[0031] In the above-described design, the first support member 12 is used to support the flexible screen that extends beyond the first surface 1000, providing strong support for the flexible screen above, especially when the user performs touch operations on the flexible screen. It can be seen that in the sliding direction X of the first support member 12, the first support member 12 includes multiple flexible members 120 arranged in parallel, with adjacent flexible members 120 interconnected to form a mesh structure. This design improves the flexibility of the first support member 12 in the sliding direction X. When subsequently stored, the first support member 12 can curl in the sliding direction with a smaller radius to reduce the volume occupied by the first support member 12, which is conducive to a lighter and thinner display device.
[0032] Please continue reading Figure 2 The support assembly 1 provided in this application also includes a second support member 16, which has a certain rigidity and a flexibility less than that of the first support member 12; the second support member 16 is used to be stacked on the side of the first support member 12 away from the flexible screen body 2 when the first support member 12 supports the flexible screen body 2.
[0033] For example, Figure 3 As shown, Figure 3 for Figure 1Schematic diagram of the structure of the central support assembly and flexible screen in one embodiment. The main body 10 supports the portion of the flexible screen 2 located on its first surface 1000; the remaining flexible screen 2 outside the main body 10 is supported by the stacked first support members 12 and second support members 16 when unfolded. The first support members 12, with a certain degree of flexibility, can better conform to the flexible screen 2, while the second support members 16, with a certain degree of rigidity, can compensate for the strength of the first support members 12. The first and second support members 12, 16 can provide strong support for the flexible screen 2 above, especially when the user performs touch operations on the flexible screen 2.
[0034] Furthermore, the second support member 16 is slidably connected to the main body 10, and the sliding direction X in which the second end 123 slides relative to the main body 10 is the same as the sliding direction X in which the second support member 16 slides relative to the main body 10. This design allows the first support member 12 and the second support member 16 to translate synchronously to provide synchronous support for the unfolded flexible screen, thereby achieving a better support effect.
[0035] In one embodiment, Figure 3 As shown, the second end 123 and the second support member 16 simultaneously approach or move away from the main body 10 along the sliding direction X. This design is relatively simple in structure.
[0036] Optionally, refer again to Figure 2 The support assembly 1 provided in the present application further includes a translation mechanism 18 slidably connected to the main body 10; wherein, in the sliding direction X, the second support member 16 includes a fixed end 164, and the second end 123 of the first support member 12 and the fixed end 164 are fixedly disposed relative to the translation mechanism 18. In the above-described design, the translation mechanism 18 can synchronously drive the second support member 16 and the second end 123 to slide relative to the main body 10, thereby reducing the difficulty of sliding the second support member 16 and the second end 123 relative to the main body 10.
[0037] Please refer again Figure 3 The support assembly 1 provided in the present application further includes a reel 14 for winding the first support member 12, and one of the first end 121 and the second end 123 is fixedly connected to the reel 14. The introduction of the reel 14 can make the process of winding and unwinding the first support member 12 simpler.
[0038] In an application scenario, such as Figure 2 and Figure 3As shown, the reel 14 can move toward or away from the main body 10 along the sliding direction X, driving the first support member 12 to wind or unwind; in this case, the reel 14 can be located outside the main body 10; for example, the reel 14 can be arranged side by side with the main body 10 in the sliding direction X in which the reel 14 slides relative to the main body 10. The first end 121 of the first support member 12 is fixedly mounted on the main body 10, and the second end 123 of the first support member 12 is fixedly mounted on the reel 14. The reel 14 can drive the first support member 12 to wind or unwind. Specifically, as the reel 14 approaches the main mechanism 10 along the sliding direction X, the second end 123 also approaches the main mechanism 10 along the sliding direction X, causing a portion of the first support member 12 to be wound around the reel 14, and the support surface area formed by the first support member 12 to decrease. As the reel 14 moves away from the main mechanism 10 along the sliding direction X, since the second end 123 is fixedly mounted on the reel 14, the second end 123 also moves away from the main mechanism 10 along the sliding direction X, causing the portion of the first support member 12 wound around the reel to unwind, and the support surface area formed by the first support member 12 to increase. In the above design, the method of driving the first support member 12 to wind or unwind via the reel 14 is relatively simple, and the process of winding or unwinding the first support member 12 can be made easier.
[0039] like Figure 2 and Figure 3 As shown, in the sliding direction X, a step portion 1002 is provided on the first surface 1000 of the main mechanism 10 adjacent to the edge of the first support member 12. The first end 121 of the first support member 12 is located within the step portion 1002 and is fixedly connected to the step portion 1002. This design can reduce the difficulty of fixing the first support member 12 to the main mechanism 10 and help reduce the thickness of the support assembly 1.
[0040] Optionally, the first end 121 of the first support member 12 may be fixedly connected to the step portion 1002 via an adhesive member or the like.
[0041] Alternatively, the main body 10 includes a first plate 100, which includes the aforementioned first surface 1000 and a second surface 1004 opposite to the first surface 1000. The first plate 100 includes the aforementioned step 1002. In a first direction Y from the first surface 1000 to the second surface 1004, the thickness of the first support member 12 is the same as the height of the step 1002. This design allows the side of the first support member 12 facing the flexible screen in the unfolded state to be flush with the first surface 1000, making the unfolded flexible screen 2 relatively flat and improving the display effect.
[0042] Please also refer to Figure 2 and Figure 4 , Figure 4 for Figure 1 A schematic structural diagram of the main body mechanism from another perspective. A receiving groove 1006 is also provided in the main body mechanism 10. At least a portion of the second support member 16 is located within the receiving groove 1006 and is slidably connected to the receiving groove 1006. In other words, the receiving groove 1006 can guide the sliding of the second support member 16. In this embodiment, the extending direction of the receiving groove 1006 is parallel to the sliding direction X mentioned above, so that the second support member 16 and the first support member 12 are deployed in the same direction, and the second support member 16 and the first support member 12 can simultaneously support the flexible screen 2.
[0043] Optionally, the step portion 1002 and the receiving groove 1006 may both be located on the first plate 100, and the receiving groove 1006 is located on one side of the second surface 1004. The structural design of the main body mechanism 10 is relatively simple.
[0044] Alternatively, as Figure 2 and Figure 4 As shown, in the first direction Y pointing from the first surface 1000 to the second surface 1004, the step portion 1002 includes a bottom portion 10020, the bottom portion 10020 includes a hollow area, the accommodating groove 1006 extends into the hollow area, and the side of the second support member 16 facing the first support member 12 is flush with the bottom portion 10020. This design allows the second support member 16 and the first support member 12 to contact each other, thereby improving the joint support effect formed by the second support member 16 and the first support member 12.
[0045] Alternatively, if Figure 2 As shown, in a second direction Z perpendicular to the sliding direction X, the second direction Z is also perpendicular to the first direction Y; the width of the main body mechanism 10 is greater than the width of the second support member 16, and the width of the receiving groove 1006 can be equal to the width of the second support member 16 slidably disposed within the receiving groove 1006. This design allows only a portion of the bottom 10020 of the step portion 1002 to be penetrated by the receiving groove 1006, while the remaining bottom 10020 not penetrated by the receiving groove 1006 can be fixedly connected to the first support member 12, thereby ensuring a secure connection between the first support member 12 and the step portion 1002.
[0046] Optionally, refer again to Figure 1 and Figure 2The support assembly 1 provided in the present application further includes a translation mechanism 18, which is slidably connected to the main body 10. In the sliding direction X in which the reel 14 slides relative to the main body 10, the second support member 16 includes a fixed end 164. The reel 14 and the fixed end 164 are fixedly connected to the translation mechanism 18, and the reel 14 is located on the side of the fixed end 164 away from the main body 10. In the above design, the translation mechanism 18 can synchronously drive the second support member 16 and the reel 14 to slide relative to the main body 10, thereby reducing the difficulty of sliding the second support member 16 and the reel 14 relative to the main body 10.
[0047] Alternatively, in a direction perpendicular to the first surface 1000 (i.e., the first direction Y), the main mechanism 10 further includes a second plate 102 disposed opposite and spaced from the first plate 100; the translation mechanism 18 includes at least one extension plate 180, which is positioned between the first and second plates 100, 102 and slidably connected thereto. For example, guide grooves are additionally provided on the first and second plates 100, 102 at positions corresponding to the extension plates 180, with the guide grooves extending parallel to the sliding direction X. The extension plates 180 are disposed within the corresponding guide grooves on either side of the extension plates 180 in the first direction Y. The sliding connection between the main mechanism 10 and the translation mechanism 18 is relatively simple.
[0048] Preferably, if Figure 2 As shown in , in the second direction Z, the translation mechanism 18 includes two extension plates 180 that are opposite and spaced apart, the first plate 100 includes two first edges 1008 that are opposite and spaced apart, and an extension plate 180 is provided at the position of each first edge 1008.
[0049] Furthermore, the fixed end 164 of the second support member 16 and the two ends of the reel 14 in the second direction Z may be fixedly connected to the two extension plates 180 respectively.
[0050] In addition, the translation mechanism 18 may further include a first connecting plate 182 connecting the two extension plates 180, and the first connecting plate 182 is located on the side of the extension plates 180 away from the main mechanism 10. Similarly, the main mechanism 10 also includes a second connecting plate 104 connecting the first plate 100 and the second plate 102, and the second connecting plate 104 is located on the side of the first plate 100 away from the translation mechanism 18.
[0051] In the above application scenario, the reel 14 is located outside the main body 10, and the reel 14 can be closer to or farther away from the main body 10. Of course, in other application scenarios, the reel 14 can also be fixed relative to the main body 10. For example, see Figure 5-Figure 6 , Figure 5This is a structural diagram of another embodiment of the support assembly and flexible screen of this application. Figure 6 for Figure 5 Schematic diagram of an exploded view of an embodiment of a support assembly. Specifically, the support assembly 1 and Figure 2 The differences between the support assemblies include: the first end 121 of the first support member 12 is fixedly mounted on the reel 14, and the reel 14 is fixed relative to the main mechanism 10. The second end 123 of the first support member 12 moves toward or away from the main mechanism 10 along a sliding direction X. Optionally, the second end 123 of the first support member 12 is fixedly connected to the translation mechanism 18 and is located on the side of the fixed end 164 of the second support member 16 away from the main mechanism 10. The reel 14 can slide in a direction toward or away from the translation mechanism 18 to drive the first support member 12 to wind or unwind, and the sliding direction X of the translation mechanism 18 relative to the main mechanism 10 is the same as the sliding direction X of the second support member 16 relative to the main mechanism 10. Specifically, because the reel 14 is fixed relative to the main mechanism 10, the reel 14 slides in a direction toward or away from the translation mechanism 18, that is, the main mechanism 10 slides in a direction toward or away from the translation mechanism 18. In other words, the translation mechanism 18 slides in a direction toward or away from the main mechanism 10. The translation mechanism 18 approaches the main mechanism 10 or the reel 14 along the sliding direction X, and the second end 123 also approaches the main mechanism 10 or the reel 14 along the sliding direction X, causing the reel 14 to wind the first support member 12. The translation mechanism 18 moves away from the main mechanism 10 or the reel 14 along the sliding direction X, and the second end 123 also moves away from the main mechanism 10 or the reel 14 along the sliding direction X, causing the reel 14 to unwind the first support member 12. The above design is relatively simple in structure and can provide better smoothness and feel, so that the first support member 12 and the second support member 16 can support a larger area of the flexible screen 2.
[0052] Alternatively, as Figure 5 and Figure 6 As shown, the reel 14 is located inside the main body 10, and the main body 10 includes a hollow portion 106, wherein the first end 121 of the first support member 12 passes through the hollow portion 106 and is fixedly connected to the reel 14. This structural design is relatively simple.
[0053] Alternatively, if Figure 5 and Figure 6 As shown, the main body 10 includes a first plate 100 and a second plate 102 that are opposite and spaced apart. The reel 14 is located in the spaced apart area between the first plate 100 and the second plate 102. The side of the first plate 100 facing away from the second plate 102 is used to support the flexible screen 2 (such as Figure 5 As shown in FIG, a hollow portion 106 is provided on the first plate 100. The structural design of the main body mechanism 10 provided with the hollow portion 106 is relatively simple.
[0054] Furthermore, the first plate 100 is provided with a receiving groove 1006 that is slidably connected to the second support member 16. The specific structure of the receiving groove 1006 can be found in the above embodiment and will not be further described here. The second support member 16 includes a fixed end 164 that is fixed to the translation mechanism 18. In the sliding direction X, the hollow portion 106 is located away from the fixed end 164 relative to the receiving groove 1006.
[0055] Optionally, the length extension direction of the accommodating groove 1006 is parallel to the sliding direction X, and the length extension direction of the hollow portion 106 is parallel to the second direction Z. And / or, one end of the first support member 12 can be fixedly connected to the fixed end 164 of the second support member 16. This design method can enable the first support member 12 and the second support member 16 to synchronously support the unfolded flexible screen 2.
[0056] See also Figure 7 , Figure 7 for Figure 2 A partial schematic diagram of an embodiment of the first support member in FIG. The flexibility of the first support member 12 in the sliding direction X is greater than its flexibility in the aforementioned second direction Z. The greater flexibility in the sliding direction X reduces the difficulty of winding the first support member 12 along the reel 14 and enables subsequent winding of the first support member 12 at a very small radius. The lower flexibility in the second direction Z allows the first support member 12 to have a certain degree of rigidity in the second direction Z when deployed, thereby improving the support effect.
[0057] Optionally, the flexible member 120 extends in a spiral shape in the second direction Z. This design can impart a certain degree of rigidity to the flexible member 120 in the second direction Z. Preferably, the wire diameter of the flexible member 120 is 0.05 mm to 1 mm (e.g., 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, etc.), and the outer diameter of the spiral formed by the flexible member 120 is 0.05 mm to 3 mm (e.g., 0.1 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, etc.). This design can reduce the thickness and winding radius of the resulting first support member 12.
[0058] Alternatively, adjacent flexible members 120 are staggered and intersected with each other in the sliding direction X to form a mesh structure. The structural design of the flexible members 120 is relatively simple, and adjacent flexible members 120 can be connected to each other without additional connectors.
[0059] Further, if Figure 7As shown, the flexible member 120 includes alternating convex portions 1200 and concave portions 1202, with the top A of the convex portion 1200 of the flexible member 120 intersecting with the bottom B of the concave portion 1202 of the adjacent flexible member 120. The above-mentioned intersecting method of forming the first support member 12 is relatively simple and easy to manufacture.
[0060] Of course, in other embodiments, the structural design of the first support member 12 may also be other. For example, see Figure 8 , Figure 8 for Figure 2 A schematic structural diagram of another embodiment of the first support member 12 is shown. The first support member 12 includes multiple connecting members 122 and multiple flexible members 120. The connecting members 122 and the flexible members 120 are arranged side by side in the sliding direction X, and adjacent flexible members 120 are connected by a connecting member 122. The structural design of the first support member 12 is relatively simple and easy to manufacture.
[0061] Alternatively, as Figure 8 As shown, in the sliding direction X, all flexible members 120 are aligned with each other. The flexible members 120 include alternating convex portions 1200 and concave portions 1202. The top A of the convex portion 1200 of one of the two adjacent flexible members 120 intersects with the connecting member 122 located between the two adjacent flexible members 120, and the bottom B of the concave portion 1202 of the other of the two adjacent flexible members 120 intersects with the connecting member 122 located between the two adjacent flexible members 120. The structural design of the first support member 12 is relatively simple and easy to manufacture.
[0062] Preferably, the connecting member 122 may be in a broken line shape, and the connecting member 122 includes corner points 1220 that are spaced apart. The intersection of the flexible member 120 and the connecting member 122 is located at the corner point 1220 .
[0063] Also, see Figure 9 , Figure 9 for Figure 2 Schematic diagram of another embodiment of the first support member. The ends 1204 of adjacent flexible members 120 intersect. This design reduces misalignment of the first support member 12 in the second direction Z during winding or unwinding. Optionally, the ends 1204 of adjacent flexible members 120 can be flush and interconnected to form a fixed locking structure, further reducing the possibility of misalignment of the first support member 12 in the second direction Z during winding or unwinding.
[0064] Further, if Figure 2As shown, the second support member 16 includes a plurality of support bars 160 and a connecting bar 162. The plurality of support bars 160 are arranged side by side in the second direction Z, and each support bar 160 can extend along the sliding direction X. The connecting bar 162 extends along the second direction Z and is fixedly connected to each support bar 160. This design can reduce the cost of the second support member 16.
[0065] For example, Figure 2 and Figure 7 As shown, since the first support member 12 has a certain rigidity in the second direction Z, a plurality of support bars 160 can be adopted for intermittent support; and the support bars 160 extending along the sliding direction X can compensate for the rigidity of the first support member 12 in the sliding direction X, so that the joint support effect of the support bars 160 and the first support member 12 is better.
[0066] Optionally, the connecting bar 162 is fixedly connected to the end of the support bar 160 that is away from the main body 10. This structural design is relatively simple; of course, in other embodiments, the number of connecting bars 162 can also be multiple, in which case the second support member 16 can also form a mesh-like structure. Optionally, the connecting bar 162 farthest from the main body 10 forms the fixed end 164 mentioned above.
[0067] Alternatively, if Figure 2 and Figure 4 As shown, the main body 10 is provided with a plurality of receiving grooves 1006, each of which extends in the same direction, and a support bar 160 is located in each receiving groove 1006 and is slidably connected to the receiving groove 1006. This structural design is relatively simple and can ensure that the sliding direction X of each support bar 160 remains the same.
[0068] Alternatively, the second support member 16 is a magnet, and the first support member 12 can be attracted by the magnet. For example, the first support member 12 can be made of stainless steel. This design can make the unfolded first support member 12 and the second support member 16 fit more closely, thereby further improving the support effect.
[0069] Alternatively, see Figure 10 , Figure 10 for Figure 2A partial schematic diagram of another embodiment of the first and second support members in FIG. When the first and second support members 12 and 16 are unfolded, the first support member 12 includes alternating first portions 124 and second portions 126. The orthographic projection of the first portion 124 on the second support member 16 overlaps with the support bar 160, while the orthographic projection of the second portion 126 on the second support member 16 is offset from the support bar 160. The mesh structure of the first portion 124 has a larger aperture than the mesh structure of the second portion 122. Generally speaking, a smaller mesh structure aperture indicates a greater support mesh density of the first support member 12, better support performance, but lower winding performance. In the above-mentioned design, in the second direction Z, the mesh structure of the first support member 12 has density variations. At the position opposite to the second support member 16 (i.e., the first part 124), the first support member 12 is relatively sparse. Although the supporting performance of the first support member 12 is weakened here, due to the support compensation by the second support member 16, the supporting performance of the entire support assembly 1 at this location is not weakened. On the contrary, the overall winding performance of the first support member 12 can be improved.
[0070] Also, please refer again to Figure 2 or Figure 6 The support bar 160 in the second support member 16 is a linear, non-retractable structure. In other embodiments, the support bar 160 can also be retractable to reduce the volume occupied by the support bar 160. Specifically, the support bar 160 includes multiple supporting portions that are slidably connected in sequence, one of which is fixedly connected to the translation mechanism 18. This design approach can reduce the volume occupied by the second support member 16.
[0071] For example, the outer sides of two adjacent support portions on the same support bar 160 are connected in a sliding manner. Figure 11 As shown, Figure 11 This is a schematic diagram of the structure of another embodiment of the support assembly of the present application. The support bar 160 includes a first support portion 1600 and a second support portion 1602. The outer side surface of the first support portion 1600 is slidably connected to the outer side surface of the second support portion 1602. The second support portion 1602 is fixedly connected to the translation mechanism 18. During deployment, the second support portion 1602 first slides along the sliding direction X following the translation mechanism 18. When the second support portion 1602 slides relative to the first support portion 1600 to the end of its travel, the second support portion 1602 then drives the first support portion 1600 to slide out of the receiving slot 1006.
[0072] Optionally, the extension length of the second support portion 1602 in the sliding direction X is the same as the extension length of the accommodating groove 1006 in the sliding direction X, and the extension length of the first support portion 1600 in the sliding direction X is less than or equal to the extension length of the accommodating groove 1006. When the extension length of the first support portion 1600 in the sliding direction X is less than the extension length of the accommodating groove 1006, as shown in FIG. Figure 11 As shown, the second support portion 1602 is provided with a groove 16020 , and the groove 16020 is used to accommodate the first support portion 1600 and is slidably connected to the first support portion 1600 .
[0073] For another example, one of the two adjacent support portions on the same support bar 160 is provided with an accommodating space, and the outer surface of the other support portion is slidably connected to the inner surface of the accommodating space. Optionally, the extension length of each support portion in the sliding direction X is the same as the extension length of the accommodating groove 1006. In an application scenario, please refer to Figure 12 , Figure 12 This is a schematic diagram of the structure of another embodiment of the support assembly of the present application. The support bar 160 includes a first support portion 1600, a second support portion 1602, and a third support portion 1604, which are slidably connected. The third support portion 1604 is fixedly connected to the translation mechanism 18. The outer surface of the second support portion 1602 is slidably connected to the inner surface of the accommodating space of the first support portion 1600, and the outer surface of the third support portion 1604 is slidably connected to the inner surface of the accommodating space of the second support portion 1602.
[0074] Also, please refer again to Figure 2 or Figure 6 , in the direction away from the main body 10, the width of the support bars 160 in the second support member 16 in the second direction Z is the same. In other embodiments, such as Figure 13 As shown, Figure 13 for Figure 2 Schematic diagram of another embodiment of the second support member. In the direction away from the main body 10, the width of the support bar 160 in the second direction Z gradually increases. Figure 14 As shown, Figure 14 for Figure 2 Schematic diagram of another embodiment of the second support member. The width of the support bar 160 in the second direction Z gradually increases in steps as it moves away from the main body 10. Generally speaking, the further away the flexible screen is from the main body, the lower its strength becomes, requiring a higher support strength from the support assembly. The above two design approaches can ensure that the support assembly provides higher support strength in the direction away from the main body.
[0075] Please refer again Figure 2 and Figure 3The support assembly 1 provided in the present application may further include: a rotating shaft 11, which is located on the side of the scroll 14 away from the main body mechanism 10 and is used to limit the sliding direction X of the flexible screen 2.
[0076] Optionally, the rotating shaft 11 is used to be fixedly connected to one end of the flexible screen 2 so that the flexible screen 2 can be wound on the rotating shaft 11. This design method can make the process of winding and unfolding the flexible screen 2 easier; and in this embodiment, the first support member 12 and the flexible screen 2 are provided separately, the flexible screen 2 is wound and stored on the rotating shaft 11, and the first support member 12 is wound and stored on the reel 14. During the winding and storage process, the first support member 12 has no squeezing effect on the flexible screen 2, reducing the probability of damage to the flexible screen 2 during the winding process.
[0077] Furthermore, the rotating shaft 11 and the reel 14 are arranged parallel to each other, and the rotating shaft 11 can be fixedly connected to the above-mentioned translation mechanism 18 .
[0078] Furthermore, the thickness of the first support member 12 is greater than the thickness of the flexible screen body 2, and the radius of the reel 14 is smaller than the radius of the rotating shaft 11. This design method can make the winding radius of the flexible screen body 2 larger during the winding process, which is beneficial to reducing the bending stress of the flexible screen body 2. Furthermore, when the first support member 12 and the flexible screen body 2 are fully wound, the cylinder formed by the reel 14 and the first support member 12 located on its periphery has a first radius, and the cylinder formed by the rotating shaft 11 and the flexible screen body 2 located on its periphery has a second radius. The first radius is smaller than the second radius, and the difference between the first radius and the second radius is the thickness of the flexible screen body 2, so that the display surface of the flexible screen body 2 exposed after being fully wound remains flat.
[0079] The present application also provides a display device, in an application scenario, such as Figure 2 、 Figure 3 and Figure 4 As shown, when the translation mechanism 18 moves along the sliding direction X away from the main mechanism 10 under the action of an external force (i.e., when the display device is unfolded), since the rotating shaft 11, the reel 14, and the second support member 16 are fixedly connected to the translation mechanism 18, the rotating shaft 11, the reel 14, and the second support member 16 will follow the translation mechanism 18 and move along the sliding direction X away from the main mechanism 10. At this time, the flexible screen 2 wound on the rotating shaft 11 unfolds, the first support member 12 wound on the reel 14 unfolds, and the second support member 16 accommodated in the receiving groove 1006 of the main mechanism 10 slides out of the receiving groove 1006 and is stacked on the side of the first support member 12 facing away from the flexible screen 2. The first support member 12 and the second support member 16 can support the flexible screen 2 located outside the main mechanism 10.
[0080] Further, if Figure 2 、 Figure 3 and Figure 4 As shown, when the translation mechanism 18 moves along the sliding direction X toward the main body 10 under the action of an external force (i.e., when the display device is rolled up), since the rotating shaft 11, the reel 14, and the second support member 16 are fixedly connected to the translation mechanism 18, the rotating shaft 11, the reel 14, and the second support member 16 will follow the translation mechanism 18 and move along the sliding direction X toward the main body 10. At this time, the flexible screen 2 located outside the main body 10 and unfolded can be rolled up on the rotating shaft 11, the first support member 12 located outside the main body 10 and unfolded can be rolled up on the reel 14, and the second support member 16 that has slid out of the accommodating groove 1006 can slide into the accommodating groove 1006.
[0081] In another application scenario, such as Figure 5 and Figure 6 As shown, when the translation mechanism 18 moves along the sliding direction X away from the main mechanism 10 under the action of an external force (i.e., when the display device is unfolded), since the rotating shaft 11 and the second support member 16 are fixedly connected to the translation mechanism 18, the rotating shaft 11 and the second support member 16 will follow the translation mechanism 18 in moving along the sliding direction X away from the main mechanism 10. Since the reel 14 is fixedly connected to the main mechanism 10, the reel 14 will follow the main mechanism 10 in moving along the sliding direction X away from the translation mechanism 18. At this time, the flexible screen 2 wound on the rotating shaft 11 unfolds, the first support member 12 wound on the reel 14 unfolds, and the second support member 16 accommodated in the receiving groove 1006 of the main mechanism 10 slides out of the receiving groove 1006 and is stacked on the side of the first support member 12 facing away from the flexible screen 2. The first support member 12 and the second support member 16 can support the flexible screen 2 located outside the main mechanism 10.
[0082] Further, if Figure 5 and Figure 6 As shown, when the translation mechanism 18 moves along the sliding direction X toward the main mechanism 10 under the action of an external force (i.e., when the display device is rolled up), since the rotating shaft 11 and the second support member 16 are fixedly connected to the translation mechanism 18, the rotating shaft 11 and the second support member 16 will follow the translation mechanism 18 in moving along the sliding direction X toward the main mechanism 10; and since the reel 14 is fixedly connected to the main mechanism 10, the reel 14 will follow the main mechanism 10 in moving along the sliding direction X toward the translation mechanism 18. At this time, the flexible screen 2, which is located outside the main mechanism 10 and has been unfolded, can be rolled up on the rotating shaft 11, the first support member 12, which is located outside the main mechanism 10 and has been unfolded, can be rolled up on the reel 14, and the second support member 16, which has slid out of the accommodating groove 1006, can slide back into the accommodating groove 1006.
[0083] In the above embodiment, the flexible screen 2 and the first support member 12 are wound separately and independently. Figure 15 As shown, Figure 15 Schematic diagram of another embodiment of the support assembly and the flexible screen. The first support member 12 is used to fit with the flexible screen 2, and the reel 14 is used to drive the flexible screen 2 and the first support member 12 to be wound or unwound together.
[0084] In addition, in the above embodiments, the display device composed of the flexible screen 2 and the support assembly 1 is a roll-up display device. Of course, in other embodiments, the flexible screen 2 and the support assembly 1 can also constitute a sliding display device. For example, Figure 16 and Figure 17 As shown, Figure 16 This is a schematic structural diagram of an embodiment of the display device of the present application. Figure 17 for Figure 16 Schematic diagram of the structure of an embodiment of the display device when it is fully unfolded. At this time, the flexible screen body 2 is partially wrapped around the side of the rotating shaft 11 away from the main body 10 and slides along the circumference of the rotating shaft 11. The flexible screen body 2 located on the side of the first plate 100 facing the second plate 102 is accommodated in a non-wound form; for example, Figure 16 As shown in , when the flexible screen 2 is not fully unfolded, the flexible screen 2 includes a first portion 20 and a second portion 22 that are connected to each other; the first portion 20 is located on the first plate 100 and can be fixedly connected to the first plate 100, and the second portion 22 is the portion of the flexible screen 2 other than the first portion 20. The sub-portion of the second portion 22 located between the first plate 100 and the second plate 102 can be arranged parallel to the first portion 20, and the second portion 22 can slide along the rotating shaft 11 away from the outside of the main body 10 to be unfolded or retracted.
[0085] Finally, the mainstream flexible screen support methods currently include perforated steel sheet and bracelet-type supports. Generally speaking, the support and curling properties of perforated steel sheets are related to their material properties, thickness, and hole density. To achieve a small curling radius, the perforated steel sheet must be thinned, the hole diameter increased, and the hole spacing reduced. However, this inevitably leads to weakened support and increased damage to the perforated steel sheet. Furthermore, the perforated steel sheet is a single piece, which accumulates significant stress during curling, resulting in large gaps between adjacent loops of perforated steel sheet. The bracelet-type support consists of joints connected by thin shafts. The curling radius depends on the joint length and the diameter of the shaft. Due to structural and manufacturing constraints, it is impossible to achieve an extremely small joint length and shaft diameter. Furthermore, because each joint is fixed by the thin shaft, it cannot move flexibly in the direction of the flexible screen's winding, and generally cannot curl with the flexible screen.
[0086] Compared with the above two types of support members, the first support member in the support assembly provided by the present application is a mesh structure composed of spiral flexible members. The connection of each spiral flexible member in the sliding direction X is very flexible and can be curled in the sliding direction X with a very small radius. At the same time, it can have a certain strength in the second direction Z. There is no locked fixed connection between the two adjacent flexible members. The connection is only achieved through a simple cross setting method, so that the first support member can flexibly move a small distance in the sliding direction X to compensate for the displacement difference caused by the difference in the neutral layer of the flexible screen during the winding process. In addition, the above-mentioned first support member and the flexible screen can be arranged side by side and wound on different axes, or they can be wound on the same axis in a fit with the flexible screen. Its design is relatively flexible. In addition, a second support member is provided below the first support member. The second support member can provide a certain support strength for the first support member and the flexible screen above. When the second support member is magnetic, the second support member can also adsorb the first support member above, so that the loose structure is tightly attached, further improving the overall strength of the first support member.
[0087] In a specific embodiment, see Figure 18 , Figure 18 for Figure 2 A partial schematic diagram of an embodiment of the first support member in the figure. Assume that the wire diameter of the flexible member in the first support member in this application is 0.3mm, the diameter D1 of the spiral formed by the flexible member is 1.2mm, and the aperture D2 of the mesh structure in the first support member is 0.5mm (i.e. 1.2-0.3*2-0.1, where 0.1 is the gap at the intersection). The curling radius of the first support member is half the spiral diameter (i.e. 0.6mm). When the first support member supports alone, it withstands a support force of 3N within a deformation range of 1mm; when the first support member and the second support member support together, and the spacing between adjacent support bars in the second support member is 50mm, the aperture of the mesh structure in the first support member is reduced to 0.1mm, and within a deformation range of 1mm, the support force borne by the area of the first support member not supported by the support bar is 8N.
[0088] For comparison, consider a perforated steel sheet with a hole diameter of 0.5 mm, a hole pitch of 0.5 mm, a thickness of 0.05 mm, and a curl radius of 1 mm. Within a 1 mm deformation range, the support force is 0.5 N. When a second support member is installed on one side of the perforated steel sheet, and the spacing between adjacent support bars is 50 mm, the support force on the area of the perforated steel sheet not supported by the support bars is 2 N.
[0089] Through the above comparison, it can be found that the first support member provided in the present application has a smaller curling radius and can improve the supporting force when flattened compared to the existing perforated steel sheet.
