Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a flexible screen module and electronic equipment. Background Art

[0002] Driven by user demand, foldable electronic devices are increasingly popular among consumers due to their large display area and strong portability. Generally, foldable electronic devices include a flexible screen module to ensure that the electronic device can switch between an unfolded state and a folded state.

[0003] Flexible screen modules usually include a flexible screen and a support structure. In order to ensure that the support structure can deform with the flexible screen, the support structure must have a certain degree of stretchability to adapt to its deformation state. Currently, the middle area of ​​the support structure is usually designed as a mesh structure to utilize the tensile deformation of the mesh structure to adapt to the deformation of the flexible screen. Figure 1 As shown, a plurality of etched holes 11 are usually formed on the support structure, each etched hole 11 penetrates the support structure along the thickness direction, and multiple etched holes in the same row extend along the Y direction. Multiple rows of etched holes are arranged along the X direction, which enables the support structure 10 to have the ability to produce tensile deformation in the X direction.

[0004] However, since the mesh structure of the support structure 10 is arranged relative to the hinge mechanism 20, when the hinge mechanism 20 is squeezed by external forces such as collision, components of the hinge mechanism 20 may pass through the etched holes 11 and directly squeeze the flexible screen, which may easily cause damage to the flexible screen. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a flexible screen module and an electronic device to solve the problem in current electronic devices that the flexible screen is easily damaged by being squeezed by the hinge mechanism.

[0006] In a first aspect, an embodiment of the present application provides a flexible screen module, which includes a support assembly and a flexible screen, wherein the support assembly includes a first support structure, a bending structure, and a second support structure that are sequentially arranged and interconnected, and the bending structure includes a first support member and a second support member that are separately arranged, wherein:

[0007] The first supporting member includes a first stack, a second stack, and a third stack; the second supporting member includes a fourth stack, a fifth stack, and a sixth stack; the second stack, the fourth stack, and the sixth stack each include correspondingly connected stacking portions and extension portions; the first stack, the stacking portions of the second stack, and the third stack are sequentially stacked on a side of the flexible screen away from its display surface; and the stacking portions of the fourth stack, the fifth stack, and the sixth stack are sequentially stacked on a side of the flexible screen away from its display surface;

[0008] The extension portion of the second stack is located outside the first stack and the third stack, the extension portions of the fourth stack and the sixth stack are each located outside the same side of the fifth stack, and a portion of the extension portion of the second stack is located between the extension portions of the fourth stack and the sixth stack.

[0009] In the second aspect, an embodiment of the present application provides an electronic device, which includes a first shell, a second shell, a hinge mechanism and the above-mentioned flexible screen module, the first shell and the second shell are rotatably connected through the hinge mechanism so that the electronic device can switch between an unfolded state and a folded state; the bending structure of the support component is opposite to the hinge component.

[0010] When the support assembly disclosed in the embodiment of the present application is used in an electronic device, even if the hinge mechanism is squeezed by external forces such as collision, since the second stack is not provided with structures such as perforations along its own thickness, it can be ensured that the parts in the hinge mechanism will not pass through the support assembly and directly apply the collision force to the flexible screen; at the same time, since the respective extended portions of the second stack, the fourth stack and the sixth stack can provide a good barrier effect for the flexible screen and the hinge mechanism, then when the hinge mechanism is hit, the respective extended portions of the aforementioned can also provide a relatively good buffering effect for the flexible screen, greatly reducing the impact amplitude and pressure of the hinge mechanism, thereby greatly improving the protection of the flexible screen.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0026] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0027] The embodiment of the present application discloses a flexible screen module, which includes a support assembly and a flexible screen. The support assembly 100 can be used to provide support for the flexible screen. The flexible screen module can be applied to electronic devices. Of course, the aforementioned electronic devices are foldable electronic devices. That is, the electronic device can switch between an unfolded state and a folded state, so that the electronic device has both a large display area and strong portability. The flexible screen may include structures such as a display layer and a touch layer. Of course, the flexible screen may also include devices such as polarizers. Considering the simplicity of the text, the flexible screen will not be introduced in detail here.

[0028] like Figure 3 and Figure 4 As shown, the support assembly 100 disclosed in the embodiment of the present application includes multiple parts, and any two adjacent parts are fixedly connected. Although the support assembly 100 includes multiple parts as described above, in the process of forming the support assembly 100, a single block structure can still be used through etching or other processing methods to enable different parts on the support assembly 100 to be formed into the multiple parts claimed in the present application.

[0029] Among them, such as Figure 3 As shown, the multiple parts included in the support component 100 may specifically include a first support structure 110, a bending structure 130 and a second support structure 120. The first support structure 110 and the second support structure 120 are used to provide support for the parts of the flexible screen that basically do not need to bend and deform. Correspondingly, the bending structure 130 is used to provide support for the parts of the flexible screen that need to bend and deform.

[0030] In other words, the flexible screen may include a first part, a second part and a third part, wherein the first part is connected to one side of the third part, and the second part is connected to the other side of the third part. The first part and the second part may be formed by a display screen with a rigid structure, and the third part may be a display screen with a flexible structure, so that the entire flexible screen still has the ability to bend and deform; or, the first part, the second part and the third part all use a display screen with a flexible structure, and the aforementioned three are only different in definition, and are essentially still an integrated structure.

[0031] Based on the above structure of the flexible screen, in the support assembly 100, the first support structure 110 can be used to provide support for the first portion, the second support structure 120 can be used to provide support for the second portion, and the bending structure 130 can be used to provide support for the third portion. In addition, the two corresponding parts (such as the first portion and the first support structure 110) can be connected to each other by bonding or other methods.

[0032] As above, combined with Figure 4 As shown, the support assembly 100 disclosed in the embodiment of the present application includes a first support structure 110, a second support structure 120, and a bending structure 130. Furthermore, the first support structure 110, the bending structure 130, and the second support structure 120 are sequentially arranged and interconnected. Specifically, the bending structure 130 is sandwiched and connected between the first support structure 110 and the second support structure 120. Thus, the deformation of the bending structure 130 enables relative movement between the first support structure 110 and the second support structure 120, thereby enabling the entire support assembly 100 to switch between a folded state and an unfolded state.

[0033] Moreover, in the support assembly 100 disclosed in the embodiment of the present application, the thickness of at least part of the bending structure 130 is smaller than the thickness of the first support structure 110 and the second support structure 120. Thus, relative to the first support structure 110 and the second support structure 120, by thinning the thickness of at least part of the bending structure 130, the bending structures 130 in the support assembly 100 have relatively good deformability. When the flexible screen needs to be folded, the deformation ability provided by the bending structure 130 located between the first support structure 110 and the second support structure 120 can be utilized, so that the middle area of ​​the entire support assembly 100 can be deformed, and the entire support assembly 100 can be switched between a folded state and an unfolded state.

[0034] More specifically, the thickness of the first support structure 110 and the second support structure 120 can be the same or different, which is not limited in this document, and the thickness of both is greater than the minimum thickness of the above-mentioned bending structure 130, so that the first support structure 110 and the second support structure 120 can provide a relatively reliable support effect for the portion of the flexible screen that basically does not need to be deformed. In addition, the thickness of the first support structure 110 and the second support structure 120 at any position can be different. In another embodiment of the present application, the thickness of the first support structure 110 and the second support structure 120 at any position are equal, and the thickness of the two is also equal, so that the support effect provided by the first support structure 110 and the second support structure 120 is the same, and there is no need to improve the specific design form of other structures such as the display layer in the flexible screen. It is also possible to ensure that the overall thickness of different positions of the first support structure 110 and the second support structure 120 in the flexible screen module is equal, thereby reducing the design difficulty of the entire flexible screen module.

[0035] In addition, since the flexible screen used in electronic devices such as mobile phones or tablets is generally rectangular in shape, in this case, the first support structure 110, the second support structure 120, and the bending structure 130 can also be generally rectangular structures. Of course, the dimensions of the above three in the distribution direction can be flexibly selected based on the actual situation such as the size of the hinge mechanism, and this is not limited herein. Moreover, if the flexible screen adopts other structural forms, the shapes of the first support structure 110, the second support structure 120, and the bending structure 130 can also adopt other forms, which will not be described in detail herein.

[0036] In order to take into account both good deformation ability and anti-extrusion ability, in the support assembly 100 disclosed in the embodiment of the present application, the bending structure 130 includes a first support member 131 and a second support member 132, and the first support member 131 and the second support member 132 are separately arranged, so that during the bending deformation process of the bending structure 130, relative movement can be generated between the first support member 131 and the second support member 132, thereby ensuring that the bending structure 130 can bend and deform normally, and basically does not cause the bending structure 130 to be stretched.

[0037] At the same time, in order to make the bending structure 130 have the ability to deform, it is also possible to improve its supporting effect as much as possible, such as Figure 4 As shown, the first support member 131 includes a first stack 1311, a second stack 1312 and a third stack 1313, and the second support member 132 includes a fourth stack 1321, a fifth stack 1322 and a sixth stack 1323, wherein the second stack 1312, the fourth stack 1321 and the sixth stack 1323 each include a correspondingly connected stacking portion 133 and an extension portion 134, the first stack 1311, the stacking portion 133 of the second stack 1312 and the third stack 1313 are stacked in sequence on the side of the flexible screen away from its display surface, and the stacking portion 133 of the fourth stack 1321, the fifth stack 1322 and the sixth stack 1323 are stacked in sequence on the side of the flexible screen away from its display surface.

[0038] Furthermore, the extension portion 134 of the second stack 1312 is located outside the first stack 1311 and the third stack 1313, the extension portions 134 of the fourth stack 1321 and the sixth stack 1323 are both located outside the same side of the fifth stack 1322, and a portion of the extension portion 134 of the second stack 1312 is located between the extension portions 134 of the fourth stack 1321 and the sixth stack 1323.

[0039] In general, in the bending structure 130, the parts on both sides adjacent to the first support structure 110 and the second support structure 120 also have relatively good supporting effects, and since the thickness of the middle part of the bending structure 130 is relatively small, it can be ensured that the bending structure 130 has relatively good bending performance.

[0040] More intuitively, the portions of the bending structure 130 adjacent to the first support structure 110 and the second support structure 120 each include at least three layers, which provides relatively good support for the two side portions of the bending structure 130. The portion relatively central to the bending structure 130, on the other hand, includes only one layer, or at most two layers, and these layers are capable of relative movement, resulting in a relatively strong bending capability for the central portion of the bending structure 130.

[0041] As described above, a portion of the extension 134 of the second stack 1312 is located between the extension 134 of the fourth stack 1321 and the sixth stack 1323, and the second stack 1312 is separable from the entire second support portion. Therefore, during the bending deformation of the bending structure 130, since the thickness of the second stack 1312 is relatively small, and the extension 134 of the second stack 1312 can gradually escape from the gap between the fourth stack 1321 and the sixth stack 1323, while ensuring that the deformation structure can bend and deform normally with the flexible screen, the extension 134 of the second stack 1312 will basically not be stretched.

[0042] It should be noted that even when the support assembly 100 is in a folded state, a portion of the extension 134 of the second stack 1312 is still located between the extensions 134 of the fourth stack 1321 and the sixth stack 1323 to ensure that the support assembly 100 can be restored to the unfolded state relatively smoothly.

[0043] As described above, the entire support assembly 100 can be formed by etching a monolithic workpiece, and the monolithic workpiece is processed into the support assembly 100 including the first support structure 110, the second support structure 120, and the deformed structure. To this end, during the processing of the support assembly 100 disclosed in the embodiment of the present application, a layered processing method can also be used. Specifically, a three-layer structure can be used to form the support component 100, and the first layer of the three-layer structure is used as the substrate for the first stack 1311 and the fourth stack 1321, as well as the corresponding parts of the first support structure 110 and the second support structure 120; the second layer is used as the substrate for the second stack 1312 and the fifth stack 1322, as well as the corresponding parts of the first support structure 110 and the second support structure 120; the third layer is used as the substrate for the third stack 1313 and the sixth stack 1323, as well as the corresponding parts of the first support structure 110 and the second support structure 120; thereafter, the support component 100 claimed in the present application can be formed by sequentially processing the aforementioned first layer, second layer and third layer substrates, and connecting the first layer, second layer substrate and third layer substrate to each other.

[0044] More specifically, the middle portion of the first substrate can be cut off, and the remaining portion of the first substrate can serve as the corresponding portions of the first support structure 110 and the second support structure 120, as well as the first laminate 1311 and the fourth laminate 1321 in the deformed structure. Subsequently, the second substrate is connected to the processed first substrate, and the middle portion of the second substrate near the second support structure 120 is cut off. The remaining portion of the second substrate can serve as the corresponding portions of the first support structure 110 and the second support structure 120, as well as the second laminate 1312 and the fifth laminate 1322 in the deformed structure. Subsequently, the third substrate is connected to the side of the processed second substrate facing away from the first substrate, and the middle portion of the second substrate is cut off. The remaining portion of the third substrate can serve as the corresponding portions of the first support structure 110 and the second support structure 120, as well as the third laminate 1313 and the sixth laminate 1323 in the deformed structure. Obviously, after completing the above process, the resulting structure is the support assembly 100 claimed in the above embodiment. Of course, the connection between the first substrate layer, the second substrate layer and the third substrate layer may be by ultrasonic welding or bonding, etc., which is not limited herein.

[0045] Of course, the above processing method is only an optional implementation method. In other embodiments of the present application, a material with a relatively large thickness can also be used to form the first support structure 110 and the second support structure 120 respectively, and the first stack 1311, the second stack 1312 and the third stack 1313 with relatively small thicknesses are connected as a whole through welding or the like, and connected to the first support structure 110, and the fourth stack 1321, the fifth stack 1322 and the sixth stack 1323 with relatively small thicknesses are connected as a whole, and connected to the second support structure 120, thereby forming the entire support assembly 100.

[0046] When the support assembly 100 disclosed in the embodiment of the present application is applied to an electronic device, even if the hinge mechanism is squeezed by external forces such as collision, since the second stack 1312 is not provided with structures such as perforations along its own thickness, it can be ensured that the parts in the hinge mechanism will not pass through the support assembly 100 and directly apply the collision force to the flexible screen; at the same time, since the respective extensions 134 of the second stack 1312, the fourth stack 1321 and the sixth stack 1323 can provide a good barrier effect for the flexible screen and the hinge mechanism, then when the hinge mechanism is hit, the respective extensions 134 of the aforementioned ones can also provide a relatively good buffering effect for the flexible screen, greatly reducing the impact amplitude and pressure of the hinge mechanism, thereby greatly improving the protection of the flexible screen.

[0047] As described above, the second laminate 1312 is not provided with any perforations or other structures along its thickness. In other words, in the embodiment of the present application, the thickness of any location on the bending structure 130 is greater than zero. In this case, when the hinge mechanism of the electronic device is squeezed by an external force, no matter how the hinge mechanism of the electronic device squeezes the bending structure 130, the structure of the bending structure 130 itself can be used to provide isolation between the flexible screen and the hinge mechanism. Moreover, since no perforations are provided at any location on the bending structure 130, the anisotropy of the bending structure 130 when squeezed is relatively poor. In other words, when any location on the bending structure 130 is subjected to a squeezing force, the effect of the force is relatively isotropic, thereby reducing the significance of the squeezing effect of the aforementioned squeezing force on a specific corresponding location on the flexible screen and improving the service life of the flexible screen.

[0048] As described above, the two side portions of the bending structure 130 adjacent to the first support structure 110 and the second support structure 120, respectively, adopt a three-layer structure to provide good support for the two side portions of the third portion of the flexible screen adjacent to the first and second portions. In one embodiment of the present application, the thickness of the first stacked layer 1311 and the fifth stacked layer 1322 of the deformable structure can be the same at any position.

[0049] To further enhance the deformation effect of the bending structure 130 and, thereby, its support for the flexible screen, in another embodiment of the present application, the third laminate 1313 of the bending structure 130 includes a first through-region 13131 and a first non-through-region 13132. The first through-region 13131 is located on the side of the first non-through-region 13132 facing away from the sixth laminate 1323, and the first through-region 13131 is provided with a plurality of perforations. In other words, the third laminate 1313 is connected to the first support structure 110 via the first through-region 13131.

[0050] In the first through-area 13131 of the third stack 1313, a plurality of perforations can be used to make the first through-area 13131 have a mesh structure, which makes the deformation ability of the first through-area 13131 greater than the deformation ability of the first non-through-area 13132, thereby improving the overall deformation ability of the part of the deformation structure where the first through-area 13131 is located, and the supporting effect on the flexible screen.

[0051] Of course, parameters such as the cross-sectional shape and size of the perforations in the first through-hole region 13131 can be flexibly selected based on practical circumstances and are not limited herein. For example, the first through-hole region 13131 can be a rectangular structure as a whole, and the perforations in the first through-hole region 13131 can all be cylindrical holes, with the multiple cylindrical holes distributed in a determinant pattern on the first through-hole region 13131 to ensure that the deformation effect is substantially the same at any location on the first through-hole region 13131.

[0052] To enhance the deformation symmetry of the support assembly 100, the sixth laminate 1323 may optionally include a second through-region 13231 and a second non-through-region 13232. Both the second through-region 13231 and the second non-through-region 13232 are included in the extension 134 of the sixth laminate 1323. Accordingly, the second through-region 13231 is located on the side of the second non-through-region facing away from the third laminate 1313, and is provided with a plurality of perforations. In other words, the second non-through-region 13232 is connected to the laminate portion 133 of the sixth laminate 1323 via the second through-region 13231, thereby integrating the sixth laminate 1323. Similarly, the second through-area 13231 can also be a rectangular structure as a whole, and correspond to the size of the first through-area 13131. The perforations on the second through-area 13231 can also be cylindrical holes, and are distributed in a determinant manner to ensure that the first through-area 13131 and the second through-area 13231 have basically the same deformation ability, thereby improving the deformation effect of the entire support assembly 100 and the support effect on the flexible screen.

[0053] As described above, in order to ensure that the deformation structure of the support assembly 100 can normally produce bending deformation, the first support member 131 and the second support member 132 are separately arranged. More specifically, the extension 134 of the second stack 1312 in the first support member 131 is separately arranged from the extension 134 of the fourth stack 1321 and the sixth stack 1323 in the second support member 132, and a portion of the extension 134 of the second stack 1312 extends between the extension 134 of the fourth stack 1321 and the sixth stack 1323.

[0054] In addition, in the above embodiments, the first support member 131 and the second support member 132 can be formed together with the first layer of substrate, the second layer of substrate and the third layer of substrate, or the first support member 131 and the second support member 132 can be formed separately and connected to the first support structure 110 and the second support structure 120 respectively to form the entire support assembly 100.

[0055] In the process of forming the support assembly 100, optionally, in the stacking direction of the fourth stack 1321 and the sixth stack 1323, the extension portion 134 of the second stack 1312 can be arranged in contact with the extension portions 134 of each of the fourth stack 1321 and the sixth stack 1323. For example, the upper surface of the extension portion 134 of the second stack 1312 is arranged in contact with the lower surface of the fourth stack 1321, and the lower surface of the extension portion 134 of the second stack 1312 is arranged in contact with the upper surface of the extension portion 134 of the sixth stack 1323.

[0056] In another embodiment of the present application, in order to reduce the relative movement difficulty between the second stack 1312 and the entire second support member 132, as shown in FIG. Figure 4 As shown, in the stacking direction of the fourth stack 1321 and the sixth stack 1323, the portion of the extension 134 of the second stack 1312 located between the fourth stack 1321 and the sixth stack 1323 is spaced apart from the extension 134 of each of the fourth stack 1321 and the sixth stack 1323. That is, the upper surface of the extension 134 of the second stack 1312 is spaced apart from the lower surface of the fourth stack 1321, and the lower surface of the extension 134 of the second stack 1312 is also spaced apart from the upper surface of the extension 134 of the sixth stack 1323. In this case, when the extension portion 134 of the second stack 1312 extends from between the fourth stack 1321 and the sixth stack 1323, and when the extension portion 134 of the second stack 1312 extends into between the fourth stack 1321 and the sixth stack 1323, the second stack 1312 can be prevented from rubbing against the fourth stack 1321 and the sixth stack 1323, thereby hindering the movement process of the second stack 1312, and the noise generated by the deformation of the support assembly 100 can be reduced.

[0057] In the case of the above embodiment, specifically, by making the thickness of the second stack 1312 smaller than the thickness of the fifth stack 1322, the portion of the second stack 1312 extending between the fourth stack 1321 and the sixth stack 1323 can be spaced apart from the extension portions 134 of each of the fourth stack 1321 and the sixth stack 1323. In this case, the thickness of the first stack 1311 can be equal to that of the fourth stack 1321, and the thickness of the third stack 1313 can be equal to that of the sixth stack 1323.

[0058] In another embodiment of the present application, the thicknesses of the first laminate 1311 and the fourth laminate 1321 can be equal, the thicknesses of the third laminate 1313 and the sixth laminate 1323 can be equal, and the thicknesses of the second laminate 1312 and the fifth laminate 1322 can be equal. Furthermore, to achieve the above technical objectives, adhesive layers 140 can be provided between the laminated portion 133 of the second laminate 1312 and the first laminate 1311, between the laminated portion 133 of the second laminate 1312 and the third laminate 1313, between the laminated portion 133 of the fourth laminate 1321 and the fifth laminate 1322, and between the laminated portion 133 of the sixth laminate 1323 and the fifth laminate 1322. In other words, an adhesive layer 140 is provided between any two adjacent layers of the first support member 131 and the second support member 132, so that the adhesive layer 140 forms a fixed connection between the two adjacent layers. At the same time, in the process of setting the adhesive layer 140, the adhesive layer 140 in the first support member 131 is extended only to the stacking portion 133 of the second stack 1312, so that the adhesive layer 140 is no longer provided on the extension portion 134 of the second stack 1312, and the adhesive layer 140 in the second support member 132 is extended only to the stacking portions 133 of each of the fourth stack 1321 and the sixth stack 1323, so that the adhesive layer 140 is no longer provided on the extension portion 134 of each of the fourth stack 1321 and the sixth stack 1323. This can also ensure that the portion of the second stack 1312 located between the fourth stack 1321 and the sixth stack 1323 can be spaced apart from the extension portions 134 of each of the fourth stack 1321 and the sixth stack 1323 in the aforementioned stacking direction.

[0059] Since the second stack 1312 itself has the ability to resist deformation, during the bending process of the support component 100, even if the thickness of the extension 134 of the second stack 1312 is smaller than the size of the gap between the extension 134 of the fourth stack 1321 and the sixth stack 1323 as described above, it is still possible that the upper surfaces of the second stack 1312 and the sixth stack 1323 will contact each other and generate dynamic friction, thereby generating noise and having a certain hindering effect on the normal movement of the second stack 1312.

[0060] To address the above situation, in one specific embodiment of the present application, a slip-enhancing structure 150 can be provided on opposite sides of the extension 134 of the second stack 1312. This slip-enhancing structure 150 reduces friction between the second stack 1312 and the fourth and sixth stacks 1321, 1323, thereby improving the smoothness of movement between the second stack 1312 and the other two stacks. Furthermore, the slip-enhancing structure 150 can also reduce friction noise when the second stack 1312 moves relative to the second support member 132, thereby improving the user experience.

[0061] Alternatively, the aforementioned slip-enhancing structure 150 may be provided on both the side of the extension portion 134 of the fourth laminate 1321 facing the sixth laminate 1323, and the side of the extension portion 134 of the sixth laminate 1323 facing the fourth laminate 1321. This can also ensure relatively smooth movement between the second laminate 1312, the fourth laminate 1321, and the sixth laminate 1323, and reduce friction noise. Of course, the aforementioned two technical solutions can be implemented together, which can further enhance the aforementioned effects.

[0062] As described above, the extension portion 134 of the second stack 1312 in the first support member 131 in the deformed structure is arranged to be extended relative to the first stack 1311 and the third stack 1313, and in the second support member 132, the extension portions 134 of the fourth stack 1321 and the sixth stack 1323 are arranged to be extended relative to the fifth stack 1322, and a portion of the second stack 1312 can extend into or out of the gap between the fourth stack 1321 and the sixth stack 1323, so that the middle area of ​​the deformed structure has only a single layer structure of the extension portion 134 of the second stack 1312. Compared with the two side parts of the deformed structure, the supporting effect of the aforementioned middle area is relatively poor.

[0063] To further enhance the structural reliability of the middle region of the deformable structure in the entire support assembly 100 and improve the strength and support effect in the aforementioned middle region, the flexible screen module disclosed in the embodiment of the present application optionally further includes a reinforcement structure 160, which is sandwiched between the first laminate 1311 and the fourth laminate 1321. The reinforcement structure 160 is formed of a material such as a deformable plastic. That is, the reinforcement structure 160 is deformable to ensure that the reinforcement structure 160 can deform with the extension 134 of the second laminate 1312. For example, the reinforcement structure 160 can be formed of polyethylene glycol terephthalate (PET), which can further enhance the adhesion between the middle region of the deformable structure of the support assembly 100 and the flexible screen. Of course, during the formation of the reinforcement structure 160, the thickness of the reinforcement structure 160 needs to be slightly smaller than the distance between the extension 134 of the second laminate 1312 and the flexible screen to prevent the presence of the reinforcement structure 160 from interfering with the movement of the second laminate 1312 relative to the second support member 132. Accordingly, in the general distribution direction of the first support members 131 and the second support members 132, it is also necessary to space the opposite sides of the reinforcement structure 160 from the first laminate 1311 and the fourth laminate 1321. It should be noted that the distribution direction of the first support members 131 and the second support members 132 can specifically be the distribution direction of the first laminate 1311 and the fourth laminate 1321 in the deployed state.

[0064] As described above, when the support assembly 100 disclosed in the embodiment of the present application is applied to an electronic device, the bending structure 130 can be arranged relative to the hinge mechanism of the electronic device. Based on this, the flexible screen module disclosed in the embodiment of the present application can also include a buffer structure, and the buffer structure is sandwiched between the third laminate 1313 and the sixth laminate 1323. That is, the buffer structure is provided on the side of the extension 134 of the second laminate 1312 facing away from the flexible screen, so that the buffer structure is used to isolate the bending structure 130 and the hinge mechanism of the support assembly 100, thereby further reducing the squeezing effect of the hinge mechanism on the flexible screen through the support assembly 100, thereby improving the display effect and service life of the flexible screen.

[0065] Specifically, the buffer structure can be formed of a relatively soft elastic material such as foam, which can be embedded between the third laminate 1313 and the sixth laminate 1323. Of course, the thickness of the buffer structure can usually be equal to or slightly less than the thickness of the third laminate 1313 and the sixth laminate 1323 to prevent the buffer structure from interfering with the normal assembly process of the flexible screen module. Of course, in view of the fact that the buffer structure has a certain elasticity, and further, in order to enhance its buffering effect, the thickness of the buffer structure can also be slightly greater than the thickness of the third laminate 1313 and the sixth laminate 1323, but cannot exceed the thickness of the third laminate 1313 and the sixth laminate 1323 by too much. The buffer structure can be bonded to the surface of the extension 134 of the second laminate 1312, or the buffer structure can be simply sandwiched between the extension 134 of the second laminate 1312 and the hinge mechanism, which can also basically ensure that the position reliability of the buffer structure is relatively high.

[0066] In order to further enhance the deformation capability of the flexible screen module disclosed in the embodiment of the present application, in the embodiment of the present application, a plurality of through holes 101 may be provided on the first support structure 110 and the second support structure 120, so that a portion of the first support structure 110 and the second support structure 120 may be formed into a mesh structure, which enables the first support structure 110 and the second support structure 120 to be stretched as the flexible screen is folded, thereby further enhancing the deformation effect of the entire support assembly 100.

[0067] Specifically, the through holes 101 are arranged along the thickness direction of the support assembly 100, and in the process of forming the through holes 101, the through holes 101 on the first support structure 110 and the second support structure 120 can be roughly distributed in a determinant. In order to further improve the stretchability of the first support structure 110 and the second support structure 120, the size of the structure sandwiched between any adjacent through holes 101 on the first support structure 110 and the second support structure 120 can be made relatively small, that is, the wall thickness of the hole wall between adjacent through holes 101 is relatively small. Of course, during the assembly process of the flexible screen module of the embodiment of the present application, it is necessary to ensure that the area where the through holes 101 of each of the first support structure 110 and the second support structure 120 are located shall not form a fixed connection relationship with the flexible screen. It is even possible to make all parts sandwiched between the area where the through holes 101 of the first support structure 110 are located and the area where the through holes of the second support structure 120 are located non-fixedly connected to the display screen, thereby ensuring that the support assembly 100 has a good deformation effect.

[0068] As mentioned above, the support assembly 100 disclosed in the above embodiments of the present application can be formed by a three-layer structure. Specifically, the support assembly 100 can be formed by three layers of steel plates and two layers of pressure-sensitive adhesive, wherein Figure 4 For example, the thicknesses of the steel plates distributed from top to bottom may be 0.05 mm, 0.03 mm, and 0.015 mm, respectively, and the thicknesses of the pressure-sensitive adhesives distributed from top to bottom may be 0.01 mm and 0.015 mm, respectively.

[0069] Based on the above, both the first support structure 110 and the second support structure 120 can include the aforementioned three layers of steel plates and two layers of pressure-sensitive adhesive. Furthermore, the portion of the deformed structure where the first laminate 1311 is located, as well as the portion where the laminated portion 133 of the fourth laminate 1321 is located, can also include the aforementioned three layers of steel plates and two layers of pressure-sensitive adhesive. Of course, it should be noted that the first through-hole region 13131, the second through-hole region 13231, and the first support structure 110 and the second support structure 120 can each be formed with partially or fully through-hole structures. The outer extensions 134 of the fourth laminate 1321 and the sixth laminate 1323 each comprise only the upper and lower layers of steel plates, excluding the intermediate steel plate and the two layers of pressure-sensitive adhesive. The outer extension 134 of the second laminate 1312 only comprises the intermediate steel plate.

[0070] Based on the flexible screen module disclosed in any of the above embodiments, the present application also discloses an electronic device, which includes a shell 2, a hinge mechanism 1 and any of the above flexible screen modules, wherein the number of shells 2 can be multiple, and the multiple shells 2 can include a first shell and a second shell, and the first shell and the second shell can form a rotational connection relationship through the hinge mechanism 1, so that the electronic device can switch between a folded state and an unfolded state. In addition, in the process of assembling the flexible screen module, the flexible screen module can be installed on the first shell and the second shell, and the bending structure 130 of the support assembly 100 in the flexible screen module is arranged relative to the hinge mechanism 1, to ensure that the flexible screen module can be deformed during the unfolding and folding action to switch between the folded state and the unfolded state.

[0071] More specifically, if Figure 5 As shown, the flexible screen module may include a first screen body 31, a second screen body 32 and a third screen body 33, wherein the first screen body 31 and the second screen body 32 are connected to each other through the third screen body 33, the first screen body 31 is opposite to the first shell, the second screen body 32 is opposite to the second shell, the third screen body 33 is opposite to the hinge mechanism 1, and the third screen body 33 includes a bending structure 130.

[0072] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
