Flexible screen module and electronic device

[0001] Cross Reference to Related Applications

[0002] The present application claims priority to the Chinese patent application No. 202410443356.6, filed on April 12, 2024, and entitled "Flexible screen module and electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application belongs to the technical field of electronic devices, and specifically relates to a flexible screen module and an electronic device. BACKGROUND

[0004] Affected by user demand, foldable electronic devices are increasingly favored by 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.

[0005] The flexible screen module generally includes a flexible screen and a support structure. In order to ensure that the support structure can deform with the flexible screen, the support structure needs to have a certain stretchability to adapt to its deformation state. At present, the middle region of the support structure is usually designed as a mesh structure to adapt to the deformation of the flexible screen by generating tensile deformation. As shown in FIG. 1, a plurality of etching holes 11 are usually formed on the support structure, each etching hole 11 penetrates the support structure along the thickness direction, and the etching holes in the same row extend along the Y direction, and the etching holes in multiple rows are arranged along the X direction, which enables the support structure 10 to have the ability to generate tensile deformation in the X direction.

[0006] However, since the mesh structure of the support structure 10 is arranged opposite to the hinge mechanism 20, when the hinge mechanism 20 is pressed by external forces such as impact, the components of the hinge mechanism 20 may directly press the flexible screen through the etching holes 11, which is easy to cause damage to the flexible screen. SUMMARY

[0007] In a first aspect, embodiments of the present application provide a flexible screen module, which comprises a support assembly and a flexible screen, the support assembly comprises a first support structure, a bending structure and a second support structure which are sequentially arranged and connected with each other, the bending structure comprises a first support piece and a second support piece which are separately arranged, wherein the first support piece comprises a first layer stack, a second layer stack and a third layer stack, the second support piece comprises a fourth layer stack, a fifth layer stack and a sixth layer stack, the second layer stack, the fourth layer stack and the sixth layer stack each comprise a layer stack part and an extension part which are connected with each other, the first layer stack, the layer stack part of the second layer stack and the third layer stack are sequentially arranged on a side of the flexible screen away from a display surface thereof, the layer stack part of the fourth layer stack, the fifth layer stack and the layer stack part of the sixth layer stack are sequentially arranged on a side of the flexible screen away from the display surface thereof; the extension part of the second layer stack is located outside the first layer stack and the third layer stack, the extension part of the fourth layer stack and the extension part of the sixth layer stack are each located outside a same side of the fifth layer stack, and a part of the extension part of the second layer stack is located between the extension part of the fourth layer stack and the extension part of the sixth layer stack.

[0008] In a second aspect, embodiments of the present application provide an electronic device, which comprises a first shell, a second shell, a hinge mechanism and the above-mentioned flexible screen module, the first shell and the second shell are rotationally connected through the hinge mechanism, so that the electronic device can be switched between an unfolded state and a folded state; the bending structure of the support assembly is opposite to the hinge assembly.

[0009] When the support assembly disclosed in the embodiments of the present application is applied to an electronic device, even if the hinge mechanism is extruded by the support assembly under the action of external force such as collision, since the second layer stack is not provided with a structure such as a through hole along its thickness, it can be ensured that the parts in the hinge mechanism will not pass through the support assembly and directly act on the flexible screen with the collision force; at the same time, since the extension part of the second layer stack, the fourth layer stack and the sixth layer stack can each provide a good barrier effect for the flexible screen and the hinge mechanism, when the hinge mechanism is subjected to a collision, the extension part of each of the foregoing can also provide a 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, and solving the problem that the flexible screen is easily damaged by the extrusion of the hinge mechanism in the current electronic device.

The drawings illustrate embodiments of the present application and, together with the description, serve to explain the principles of the present application. In the drawings: DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0017] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be exchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0018] The embodiment of the present application discloses a flexible screen module, which comprises a supporting assembly and a flexible screen. The supporting assembly 100 can be used to provide support for the flexible screen. The flexible screen module can be applied to an electronic device. Of course, the aforementioned electronic device belongs to a foldable electronic device. That is, the electronic device can be switched between an unfolded state and a folded state, so that the electronic device has a larger display area and stronger portability. The flexible screen can comprise a display layer, a touch layer and other structures. Of course, the flexible screen can also comprise a polarizer and other devices. For the sake of brevity, the flexible screen will not be described in detail here.

[0019] As shown in FIGS. 3 and 4, in the supporting assembly 100 disclosed by the embodiment of the present application, a plurality of parts are included, and a fixed connection relationship is formed between any two adjacent parts in the plurality of parts. Although the supporting assembly 100 comprises a plurality of parts as described above, during the formation of the supporting assembly 100, a whole structure can still be used for processing by etching and other methods, so that different parts of the supporting assembly 100 can be formed into the plurality of parts claimed by the present application.

[0020] As shown in FIG. 3, the plurality of parts included in the supporting assembly 100 can specifically comprise a first supporting structure 110, a bending structure 130 and a second supporting structure 120. The first supporting structure 110 and the second supporting structure 120 are used to provide support for the parts of the flexible screen that do not need to be bent and deformed. Correspondingly, the bending structure 130 is used to provide support for the parts of the flexible screen that need to be bent and deformed.

[0021] In other words, the flexible screen can comprise a first part, a second part and a third part. 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 can be formed by a hard display screen, and the third part can be formed by a flexible display screen, so that the entire flexible screen still has the ability to bend and deform. Alternatively, the first part, the second part and the third part are all formed by a flexible display screen, and the aforementioned three parts are only different in definition, and are essentially an integrated structure.

[0022] Based on the above structure of the flexible screen, in the supporting assembly 100, the first supporting structure 110 can be used to provide support for the first part, the second supporting structure 120 can be used to provide support for the second part, and the bending structure 130 can be used to provide support for the third part. In addition, the aforementioned two corresponding parts (such as the first part and the first supporting structure 110) can be connected to each other by adhesion or other methods.

[0023] As described above and in combination with FIG. 4, the support assembly 100 disclosed in the embodiments of the present application comprises the first support structure 110, the second support structure 120 and the bending structure 130, and meanwhile, the first support structure 110, the bending structure 130 and the second support structure 120 are sequentially arranged and connected with each other. That is, the bending structure 130 is arranged between and connected with the first support structure 110 and the second support structure 120, so that the first support structure 110 and the second support structure 120 can relatively move under the deformation of the bending structure 130, and thus the entire support assembly 100 can switch between the folded state and the unfolded state.

[0024] In the support assembly 100 disclosed in the embodiments 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, so that the bending structure 130 in the support assembly 100 has a relatively good deformability by reducing the thickness of at least part of the bending structure 130 relative to the first support structure 110 and the second support structure 120, and thus the middle region of the entire support assembly 100 can be deformed and the entire support assembly 100 can switch between the folded state and the unfolded state by using the deformability of the bending structure 130 arranged between the first support structure 110 and the second support structure 120 when the flexible screen needs to be folded.

[0025] 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 herein, and the thickness of both is greater than the minimum thickness of the 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 part of the flexible screen which 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 thereof can be different, and in another embodiment of the present application, the thickness of the first support structure 110 and the second support structure 120 at any position thereof is equal, and the thickness of both 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 the overall thickness of different positions of the first support structure 110 and the second support structure 120 in the flexible screen module can be ensured to be equivalent without improving the specific design form of the display layer and other structures of the flexible screen, thereby reducing the design difficulty of the entire flexible screen module.

[0026] In addition, since the flexible screen applied to the electronic device such as the mobile phone or the tablet computer 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, and of course, the sizes of the three in the distribution direction can be selected flexibly according to the size of the hinge mechanism and other actual conditions, which is not limited herein. In addition, when the flexible screen has other structural forms, the shapes of the first support structure 110, the second support structure 120 and the bending structure 130 can also have other forms, which will not be described in detail herein.

[0027] In order to balance the good deformation ability and the extrusion resistance, in the support assembly 100 disclosed in the embodiments of the present application, the bending structure 130 includes the first support piece 131 and the second support piece 132, and the first support piece 131 and the second support piece 132 are arranged separately, so that the relative movement between the first support piece 131 and the second support piece 132 can be generated in the process of the bending deformation of the bending structure 130, thereby ensuring that the bending structure 130 can be deformed normally and basically without stretching.

[0028] In order to make the bending structure 130 have the deformation ability and also improve the support effect as much as possible, as shown in FIG. 4, the first support piece 131 includes the first laminated layer 1311, the second laminated layer 1312 and the third laminated layer 1313, and the second support piece 132 includes the fourth laminated layer 1321, the fifth laminated layer 1322 and the sixth laminated layer 1323, wherein the second laminated layer 1312, the fourth laminated layer 1321 and the sixth laminated layer 1323 each include a corresponding connecting layer 133 and an extension layer 134, the first laminated layer 1311, the connecting layer 133 of the second laminated layer 1312 and the third laminated layer 1313 are sequentially laminated on the side of the flexible screen away from the display surface, and the connecting layer 133 of the fourth laminated layer 1321, the fifth laminated layer 1322 and the connecting layer 133 of the sixth laminated layer 1323 are sequentially laminated on the side of the flexible screen away from the display surface.

[0029] In addition, the extension layer 134 of the second laminated layer 1312 is located outside the first laminated layer 1311 and the third laminated layer 1313, the extension layers 134 of the fourth laminated layer 1321 and the sixth laminated layer 1323 are each located outside the same side of the fifth laminated layer 1322, and part of the extension layer 134 of the second laminated layer 1312 is located between the extension layers 134 of the fourth laminated layer 1321 and the sixth laminated layer 1323.

[0030] In general, the two sides of the bending structure 130, which are adjacent to the first support structure 110 and the second support structure 120 respectively, have relatively good support effect, and the middle part of the bending structure 130 has relatively small thickness, so that the bending structure 130 has relatively good bending performance.

[0031] More intuitively, the two sides of the bending structure 130, which are adjacent to the first support structure 110 and the second support structure 120 respectively, at least include three-layer structure, so that the two sides of the bending structure 130 have relatively good support effect. The relatively central part of the bending structure 130 only includes one-layer structure or at most two-layer structure, and the one-layer structure and the two-layer structure have relatively movement ability, so that the relatively central part of the bending structure 130 has relatively strong bending performance.

[0032] As described above, a part of the extension part 134 of the second layer 1312 is located between the extension parts 134 of the fourth layer 1321 and the sixth layer 1323, and the second layer 1312 is in separable state with the whole second support part, so that in the process of the bending structure 130 being deformed by bending, since the thickness of the second layer 1312 is relatively small, and the extension part 134 of the second layer 1312 can gradually escape from the gap between the fourth layer 1321 and the sixth layer 1323, the extension part 134 of the second layer 1312 is basically not stretched while ensuring that the deformed structure can normally deform with the flexible screen by bending.

[0033] It should be noted that even in the folded state of the support assembly 100, a part of the extension part 134 of the second layer 1312 is still located between the extension parts 134 of the fourth layer 1321 and the sixth layer 1323, so as to ensure that the support assembly 100 can be restored to the unfolded state more smoothly.

[0034] As described above, the entire support assembly 100 can be formed by etching a whole workpiece, and the whole workpiece is processed to form the support assembly 100 including the first support structure 110, the second support structure 120 and the deformation structure. For this purpose, in the process of processing the support assembly 100 disclosed in the embodiments of the present application, the support assembly 100 can also be formed by layer-by-layer processing. Specifically, the support assembly 100 can be formed by a three-layer structure, and the first layer of the three-layer structure is used as the first layer 1311 and the fourth layer 1321 of the first support structure 110 and the second support structure 120, and the second layer is used as the second layer 1312 and the fifth layer 1322 of the first support structure 110 and the second support structure 120, and the third layer is used as the third layer 1313 and the sixth layer 1323 of the first support structure 110 and the second support structure 120; then, the first layer, the second layer and the third layer of the substrate can be processed in sequence, and the first layer, the second layer and the third layer are connected to each other to form the support assembly 100 claimed in the present application.

[0035] More specifically, the middle part of the first layer of the substrate can be cut off, and the remaining part of the first layer of the substrate can be used as the first support structure 110 and the second support structure 120, and the first layer 1311 and the fourth layer 1321 of the deformation structure; then, the second layer of the substrate is connected to the first layer of the substrate which has been processed, and the middle part of the second layer of the substrate close to the second support structure 120 is cut off, and the remaining part of the second layer of the substrate can be used as the first support structure 110 and the second support structure 120, and the second layer 1312 and the fifth layer 1322 of the deformation structure; then, the third layer of the substrate is connected to the side of the second layer of the substrate away from the first layer of the substrate, and the middle part of the second layer of the substrate is cut off, and the remaining part of the third layer of the substrate can be used as the first support structure 110 and the second support structure 120, and the third layer 1313 and the sixth layer 1323 of the deformation structure. Obviously, after the above process is completed, the structure formed is the support assembly 100 claimed in the above embodiments. Of course, the connection between the first layer of the substrate, the second layer of the substrate and the third layer of the substrate can be achieved by ultrasonic welding or adhesion, which is not limited in the present application.

[0036] Of course, the above processing mode is only an optional embodiment, in other embodiments of the present application, a relatively thick material can be used to form the first support structure 110 and the second support structure 120 respectively, and the first laminated layer 1311, the second laminated layer 1312 and the third laminated layer 1313 with relatively small thickness are connected into one body by welding or the like, and connected with the first support structure 110, and the fourth laminated layer 1321, the fifth laminated layer 1322 and the sixth laminated layer 1323 with relatively small thickness are connected into one body, and connected with the second support structure 120, thereby forming the entire support assembly 100.

[0037] When the support assembly 100 disclosed in the embodiments of the present application is applied to an electronic device, even if the hinge mechanism is extruded by the support assembly 100 under the action of external force such as impact, since the second laminated layer 1312 is not provided with a structure such as a hole along the thickness thereof, it can be ensured that the parts in the hinge mechanism will not pass through the support assembly 100 to directly act on the flexible screen with the impact force; at the same time, since the extension parts 134 of the second laminated layer 1312, the fourth laminated layer 1321 and the sixth laminated layer 1323 can provide good blocking action for the flexible screen and the hinge mechanism, when the hinge mechanism is impacted, the extension parts 134 of the foregoing can also provide good buffering action for the flexible screen, greatly reducing the impact amplitude and pressure of the hinge mechanism, thereby greatly improving the protection of the flexible screen.

[0038] As described above, the second laminated layer 1312 is not provided with a structure such as a hole along the thickness thereof, in other words, in the embodiments of the present application, the thickness of any part of the bending structure 130 is greater than zero. In this case, when the hinge mechanism of the electronic device is extruded by external force, no matter how the hinge mechanism of the electronic device extrudes the bending structure 130, the bending structure 130 itself can be used to provide isolation between the flexible screen and the hinge mechanism, and since the bending structure 130 does not have a hole at any position, the anisotropy of the bending structure 130 is relatively poor when it is extruded, or in other words, when any position of the bending structure 130 is extruded by the extrusion force, the isotropy of the effect of the extrusion force is relatively strong, thereby reducing the significance of the extrusion effect of the extrusion force on a specific corresponding position on the flexible screen, and improving the service life of the flexible screen.

[0039] As described above, the two side parts 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 parts of the third part of the flexible screen adjacent to the first part and the second part. In an embodiment of the present application, the thickness of any position in the part where the first laminated layer 1311 and the fifth laminated layer 1322 of the deformation structure are located can be the same.

[0040] To further improve the deformation effect of the bending structure 130, and thus improve the supporting effect of the bending structure 130 on the flexible screen, in another embodiment of the present application, the third layer 1313 of the bending structure 130 includes a first through region 13131 and a first non-through region 13132, wherein the first through region 13131 is located on the side of the first non-through region 13132 away from the sixth layer 1323, and the first through region 13131 is provided with a plurality of perforations. Or, the third layer 1313 is connected with the first support structure 110 through the first through region 13131.

[0041] In the first through region 13131 of the third layer 1313, the plurality of perforations can make the first through region 13131 have a mesh structure, which makes the deformation ability of the first through region 13131 greater than that of the first non-through region 13132, thereby improving the overall deformation ability of the part where the first through region 13131 is located in the deformation structure, and the supporting effect on the flexible screen.

[0042] Of course, the cross-sectional shape and size of the perforations on the first through region 13131 and other parameters can be flexibly selected according to actual conditions, which are not limited herein. For example, the first through region 13131 can also be a rectangular structure as a whole, and the perforations on the first through region 13131 can all be cylindrical holes, and the plurality of cylindrical holes are arranged in a matrix on the first through region 13131 to ensure that the deformation effect at any position on the first through region 13131 is basically equivalent.

[0043] To improve the deformation symmetry of the support assembly 100, optionally, the sixth layer 1323 can include a second through region 13231 and a second non-through region 13232, of course, the second through region 13231 and the second non-through region 13232 are included in the extended part 134 of the sixth layer 1323. Correspondingly, the second through region 13231 is located on the side of the second non-through region 13232 away from the third layer 1313, and the second through region 13231 is provided with a plurality of perforations. That is, the second non-through region 13232 is connected with the layered part 133 of the sixth layer 1323 through the second through region 13231, so that the sixth layer 1323 is integrated. Similarly, the second through region 13231 can also have a rectangular structure as a whole, and the size of the second through region 13231 corresponds to that of the first through region 13131, and the perforations on the second through region 13231 can also be cylindrical holes arranged in a matrix, so as to ensure that the first through region 13131 and the second through region 13231 have basically the same deformation ability, and improve the deformation effect of the entire support assembly 100 and the supporting effect on the flexible screen.

[0044] As described above, in order to ensure that the deformation structure of the support assembly 100 can normally generate the bending deformation, the first support member 131 is arranged separately from the second support member 132. More specifically, the extension part 134 of the second layer 1312 in the first support member 131 is arranged separately from the extension part 134 of the fourth layer 1321 and the sixth layer 1323 in the second support member 132, and a part of the extension part 134 of the second layer 1312 extends into between the extension part 134 of the fourth layer 1321 and the extension part 134 of the sixth layer 1323.

[0045] In addition, in the above embodiment, the first support member 131 and the second support member 132 can be formed together by using the first layer substrate, the second layer substrate and the third layer 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.

[0046] In the process of forming the support assembly 100, the extension part 134 of the second layer 1312 can be arranged in contact with the extension part 134 of the fourth layer 1321 and the extension part 134 of the sixth layer 1323 in the stacking direction of the fourth layer 1321 and the sixth layer 1323. For example, the upper surface of the extension part 134 of the second layer 1312 is arranged in abutment with the lower surface of the fourth layer 1321, and the lower surface of the extension part 134 of the second layer 1312 is arranged in abutment with the upper surface of the extension part 134 of the sixth layer 1323.

[0047] In another embodiment of the present application, in order to reduce the difficulty of relative movement between the second layer 1312 and the entire second support member 132, as shown in FIG. 4, the part of the extension part 134 of the second layer 1312 between the fourth layer 1321 and the sixth layer 1323 is spaced apart from the extension part 134 of the fourth layer 1321 and the extension part 134 of the sixth layer 1323 in the stacking direction of the fourth layer 1321 and the sixth layer 1323. That is, the upper surface of the extension part 134 of the second layer 1312 is spaced apart from the lower surface of the fourth layer 1321, and the lower surface of the extension part 134 of the second layer 1312 is also spaced apart from the upper surface of the extension part 134 of the sixth layer 1323. In this case, when the extension part 134 of the second layer 1312 extends from between the fourth layer 1321 and the sixth layer 1323, and when the extension part 134 of the second layer 1312 extends into between the fourth layer 1321 and the sixth layer 1323, the second layer 1312 can be prevented from rubbing against the fourth layer 1321 and the sixth layer 1323, thereby hindering the movement process of the second layer 1312, and the noise generated by the deformation of the support assembly 100 can be reduced.

[0048] In the case of using the above-described embodiments, specifically, the portion of the second layer 1312 that extends between the fourth layer 1321 and the sixth layer 1323 can be spaced apart from the respective extension portions 134 of the fourth layer 1321 and the sixth layer 1323 by making the thickness of the second layer 1312 smaller than the thickness of the fifth layer 1322. In this case, the first layer 1311 can have a thickness equivalent to that of the fourth layer 1321, and the third layer 1313 can have a thickness equivalent to that of the sixth layer 1323.

[0049] In another embodiment of the present application, the thickness of the first layer 1311 can be equivalent to that of the fourth layer 1321, the thickness of the third layer 1313 can be equivalent to that of the sixth layer 1323, and the thickness of the second layer 1312 can be equivalent to that of the fifth layer 1322. Meanwhile, in order to achieve the above-described technical purpose, the bonding layer 140 can be provided between the layering portion 133 of the second layer 1312 and the first layer 1311, between the layering portion 133 of the second layer 1312 and the third layer 1313, between the layering portion 133 of the fourth layer 1321 and the fifth layer 1322, and between the layering portion 133 of the sixth layer 1323 and the fifth layer 1322. In other words, the bonding layer 140 can be provided between any two adjacent layers of the first support 131 and the second support 132 to form a fixed connection relationship between the two adjacent layers by using the bonding layer 140. Meanwhile, in the process of providing the bonding layer 140, the bonding layer 140 in the first support 131 can extend only to the layering portion 133 of the second layer 1312, so that the extension portion 134 of the second layer 1312 is no longer provided with the bonding layer 140, and the bonding layer 140 in the second support 132 can extend only to the layering portion 133 of the fourth layer 1321 and the sixth layer 1323, so that the extension portion 134 of the fourth layer 1321 and the sixth layer 1323 is no longer provided with the bonding layer 140, which can also ensure that the portion of the second layer 1312 between the fourth layer 1321 and the sixth layer 1323 can be spaced apart from the respective extension portions 134 of the fourth layer 1321 and the sixth layer 1323 in the layering direction.

[0050] Since the second layer 1312 itself has the ability to resist deformation, even if the thickness of the extension portion 134 of the second layer 1312 is smaller than the size of the gap between the extension portions 134 of the fourth layer 1321 and the sixth layer 1323 as described above, it is still possible that the second layer 1312 and the upper surface of the sixth layer 1323 come into contact with each other and generate dynamic friction, which in turn generates noise and hinders the normal movement of the second layer 1312.

[0051] In view of the above, in one embodiment of the present application, the glide structure 150 can be arranged on the opposite sides of the epitaxial part 134 of the second stack 1312, so as to reduce the friction between the second stack 1312 and the fourth stack 1321 and the sixth stack 1323 by means of the glide structure 150, and improve the smoothness of the movement between the second stack 1312 and the other two. In addition, under the action of the glide structure 150, the friction noise generated when the second stack 1312 moves relative to the second support 132 can also be reduced to some extent, thereby improving the user experience.

[0052] Alternatively, the glide structure 150 can also be arranged on the side of the epitaxial part 134 of the fourth stack 1321 facing the sixth stack 1323, and on the side of the epitaxial part 134 of the sixth stack 1323 facing the fourth stack 1321, which can also ensure that the smoothness of the movement between the second stack 1312 and the fourth stack 1321 and the sixth stack 1323 is relatively good, and the friction noise can be reduced. Of course, the above two technical solutions can be implemented together, which can further improve the above effects.

[0053] As described above, in the deformation structure, the epitaxial part 134 of the second stack 1312 in the first support 131 is arranged relative to the first stack 1311 and the third stack 1313, and in the second support 132, the epitaxial parts 134 of the fourth stack 1321 and the sixth stack 1323 are arranged relative to the fifth stack 1322, and a part of the second stack 1312 can extend into or out of the gap between the fourth stack 1321 and the sixth stack 1323, which makes the middle region of the deformation structure only have the epitaxial part 134 of the second stack 1312, and the support effect of the above-mentioned middle region is relatively poor compared with the two side parts of the deformation structure.

[0054] To further improve the structural reliability of the middle region of the deformation structure in the whole support assembly 100, and improve the strength and support effect at the aforementioned middle region, optionally, the flexible screen module disclosed by the embodiments of the present application further comprises a reinforcing structure 160, which is clamped between the first laminated layer 1311 and the fourth laminated layer 1321. The reinforcing structure 160 is formed of deformable plastic material or the like, that is, the reinforcing structure 160 is deformable to ensure that the reinforcing structure 160 has the ability to deform with the extension part 134 of the second laminated layer 1312. For example, the reinforcing structure 160 can be formed of polyethylene glycol terephthalate (PET), which can further improve the fitting effect between the middle region of the deformation structure of the support assembly 100 and the flexible screen. Of course, in the process of forming the reinforcing structure 160, the thickness of the reinforcing structure 160 needs to be slightly smaller than the distance between the extension part 134 of the second laminated layer 1312 and the flexible screen, so as to prevent the existence of the reinforcing structure 160 from hindering the movement of the second laminated layer 1312 relative to the second support 132. Accordingly, in the distribution direction of the aforementioned first support 131 and second support 132, the opposite sides of the reinforcing structure 160 also need to be spaced apart from the first laminated layer 1311 and the fourth laminated layer 1321, respectively. It should be noted that the distribution direction of the aforementioned first support 131 and second support 132 can be the distribution direction of the first laminated layer 1311 and the fourth laminated layer 1321 in the unfolded state.

[0055] As described above, when the support assembly 100 disclosed by the embodiments of the present application is applied to an electronic device, the bending structure 130 can be arranged opposite to the hinge mechanism of the electronic device. Based on this, the flexible screen module disclosed by the embodiments of the present application can further comprise a buffer structure, and the buffer structure is clamped between the third laminated layer 1313 and the sixth laminated layer 1323. That is, the buffer structure is arranged on the side of the extension part 134 of the second laminated layer 1312 away from the flexible screen, so as to isolate the bending structure 130 of the support assembly 100 and the hinge mechanism, thereby further reducing the extrusion effect of the hinge mechanism on the flexible screen through the support assembly 100, and further improving the display effect and service life of the flexible screen.

[0056] Specifically, the buffer structure can be formed of a relatively soft elastic material such as foam, which can be embedded between the third layer 1313 and the sixth layer 1323. Of course, the thickness of the buffer structure can be equal to or slightly smaller than the thickness of each of the third layer 1313 and the sixth layer 1323, so as to prevent the buffer structure from interfering with the normal assembly process of the flexible screen module. Of course, since the buffer structure has a certain elastic capacity, in order to improve its buffering effect, the thickness of the buffer structure can also be slightly larger than the thickness of each of the third layer 1313 and the sixth layer 1323, but cannot exceed the thickness of each of the third layer 1313 and the sixth layer 1323 too much. The buffer structure can be attached to the surface of the extension part 134 of the second layer 1312, or the buffer structure can be only sandwiched between the extension part 134 of the second layer 1312 and the hinge mechanism, which can also basically ensure that the position reliability of the buffer structure is relatively high.

[0057] In order to further improve the deformation capability of the flexible screen module disclosed in the embodiments of the present application, a plurality of through holes 101 can also be provided on the first support structure 110 and the second support structure 120 in the embodiments of the present application, so that a part of the first support structure 110 and the second support structure 120 can be formed as a mesh structure, which enables the first support structure 110 and the second support structure 120 to also be stretched with the folding of the flexible screen, thereby further improving the deformation effect of the entire support assembly 100.

[0058] Specifically, the through holes 101 are provided in 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 arranged in a matrix. In order to further improve the stretchable effect 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 relatively small, that is, the wall thickness of the hole wall between adjacent through holes 101 is relatively small. Of course, in the assembly process of the flexible screen module in the embodiments of the present application, it is necessary to ensure that the area where the through holes 101 of the first support structure 110 and the second support structure 120 are located is not in a fixed connection relationship with the flexible screen, and even all the 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 can be arranged in a non-fixed connection with the display screen, so as to ensure that the support assembly 100 has good deformation effect.

[0059] As described above, the support assembly 100 disclosed in the above embodiments of the present application can all be formed in 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. For example, as shown in FIG. 4, the thicknesses of the steel plates arranged from top to bottom can be 0.05 mm, 0.03 mm and 0.015 mm, respectively, and the thicknesses of the pressure-sensitive adhesive arranged from top to bottom can be 0.01 mm and 0.015 mm, respectively.

[0060] Based on the above, the first support structure 110 and the second support structure 120 can both include the aforementioned three layers of steel plates and two layers of pressure-sensitive adhesive, and the portion where the first stack 1311 in the deformation structure is located and the portion where the layer-stacking portion 133 of the fourth stack 1321 is located also both include the aforementioned three layers of steel plates and two layers of pressure-sensitive adhesive. Of course, it should be noted that, for the first through-penetrating region 13131, the second through-penetrating region 13231, and the first support structure 110 and the second support structure 120, holes can be formed in the aforementioned structures in a partially or fully penetrating manner. For the extension portion 134 of the fourth stack 1321 and the extension portion 134 of the sixth stack 1323, only the upper and lower layers of steel plates are included, and the middle layer of steel plate and the two layers of pressure-sensitive adhesive are not included. For the extension portion 134 of the second stack 1312, only the middle layer of steel plate is included.

[0061] Based on the flexible screen module disclosed in any of the above embodiments, the present application further discloses an electronic device, which includes a housing 2, a hinge mechanism 1 and any of the above flexible screen modules. The number of the housings 2 can be multiple, and the multiple housings 2 can include a first housing and a second housing, and the first housing and the second housing can be rotationally connected through the hinge mechanism 1, so that the electronic device can be switched between a folded state and an unfolded state. During assembly of the flexible screen module, the flexible screen module can be mounted on the first housing and the second housing, and the bending structure 130 of the support assembly 100 in the flexible screen module can be arranged opposite to the hinge mechanism 1, so as to ensure that the flexible screen module can be deformed during unfolding and folding actions, so as to be switched between the folded state and the unfolded state.

[0062] More specifically, as shown in FIG. 5, the flexible screen module can include a first screen body 31, a second screen body 32 and a third screen body 33. 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 housing, the second screen body 32 is opposite to the second housing, the third screen body 33 is opposite to the hinge mechanism 1, and the third screen body 33 includes the bending structure 130.
