[0046] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0047] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0048] Please refer to Figure 1 , Figure 1 1 is a three-dimensional schematic diagram of an electronic device provided in an embodiment of the present application. The present application provides an electronic device 100. Specifically, the electronic device 100 can be any of various types of computer system devices that are mobile or portable and perform wireless communication ( Figure 1Specifically, the electronic device 100 may be a mobile phone or a smart phone (e.g., a phone based on iPhone TM, a phone based on Android TM), a portable gaming device (e.g., Nintendo DS TM, PlayStation Portable TM, Gameboy Advance TM, iPhone TM), a laptop computer, a PDA, a portable Internet device, a music player, and a data storage device, other handheld devices, and headsets, etc. The electronic device 100 may also be other wearable devices that need to be charged (e.g., a head mounted device (HMD) such as an electronic bracelet, an electronic necklace, an electronic device, or a smart watch).

[0049] The electronic device 100 can also be any one of a plurality of electronic devices, including but not limited to cellular phones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, radios, medical devices, vehicle transportation instruments, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbook computers, personal digital assistants (PDAs), portable multimedia players (PMPs), Moving Picture Experts Group (MPEG-1 or MPEG-2) Audio Layer 3 (MP3) players, portable medical devices, and digital cameras and combinations thereof.

[0050] In some cases, the electronic device 100 can perform multiple functions (e.g., play music, display video, store pictures, and receive and send phone calls). If desired, the electronic device 100 can be a device such as a cellular phone, a media player, other handheld devices, a wristwatch device, a pendant device, a handset device, or other compact portable device.

[0051] It should be noted that the terms "first", "second", and "third" in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0052] Taking a mobile phone as an example, the electronic device 100 may be a foldable screen mobile phone, a straight-type mobile phone, or a pull-out screen mobile phone, and no specific limitation is made here.

[0053] Please refer to Figure 2 , Figure 2 yes Figure 1The present application provides an electronic device 100, which may include a support sheet 10, a screen assembly 20 and a housing assembly 30, wherein the support sheet 10 is located between the housing assembly 30 and the screen assembly 20, and specifically, the support sheet 10 and the screen assembly 20 are stacked to support the screen assembly 20.

[0054] Please refer to Figure 3 and Figure 4 , Figure 3 is a cross-sectional schematic diagram of an electronic device in the related art, Figure 4 yes Figure 3 A partial enlarged view of the area A shown. In the related art, the electronic device 600 takes a folding screen mobile phone as an example, and the electronic device 600 may include a support layer 601, a screen assembly 602 and a shell assembly 603, wherein the support layer 601 is located between the shell assembly 603 and the screen assembly 602, and the support layer 601 and the screen assembly 602 are stacked and support the screen assembly 602, which is used to support the screen assembly 602 and improve the reliability of the screen assembly 602. The shell assembly 603 includes a hinge structure 6031 and a first shell 6032 and a second shell 6033 connected to both ends of the hinge structure 6031, and both ends of the display screen assembly are connected to the first shell 6032 and the second shell 6033. One side surface of the support layer 601 is connected to the first shell 6032, the hinge structure 6031 and the second shell 6033, and the other side surface is stacked with the screen assembly 602, and the screen assembly 602 can be deformed synchronously with the support layer 601.

[0055] As the electronic device 600 becomes thinner and lighter, the hinge structure 6031 and the screen assembly 602 have an obvious trend of reducing weight and thickness. However, as the size of the hinge structure 6031 becomes smaller, the supporting strength of the components in the hinge structure 6031 also becomes weaker, which seriously affects the reliability of the screen assembly 602. The support layer 601 is located between the flexible screen and the shell assembly 603, and is used to improve the reliability of the screen assembly 602. The support layer 601 usually includes a stacked thin steel sheet 6011 and a buffer layer 6012. However, when the electronic device 600 is bent, due to the constraint of the thin steel sheet 6011, the area corresponding to the hinge structure 6031 cannot provide enough space for deformation for the screen assembly 602, which makes the local stress of the screen assembly 602 too high and unable to be released, thereby causing failure phenomena such as color spots and black masses.

[0056] Please refer to Figures 5 to 11 , Figure 5 yes Figure 1 A schematic cross-sectional view of the electronic device shown; Figure 6 yes Figure 5 A partial enlarged view of area B in the electronic device shown; Figure 7 yes Figure 6A partial cross-sectional schematic diagram of a support sheet in the electronic device shown;

[0057] Figure 8 yes Figure 7 A schematic cross-sectional view of a deformation of the support sheet shown; Fig. 9 yes Figure 7 A cross-sectional schematic diagram of another deformation of the support sheet shown; Fig.10 yes Figure 8 A schematic diagram of the force of an embodiment of the support sheet shown in FIG. Fig.11 yes Figure 8 A force diagram of another embodiment of the support sheet shown. Specifically, the support sheet 10 may include a substrate 11 and a plurality of elastic structures 12 disposed on the substrate 11. The substrate 11 and the screen assembly 20 are stacked and arranged, and the substrate 11 may include a first surface 111 and a second surface 112 disposed opposite to each other, and the plurality of elastic structures 12 may be disposed on the first surface 111 and / or the second surface 112.

[0058] Please refer to Fig.10 It can be understood that when the screen assembly 20 is squeezed by the vertical force F, the multiple elastic structures 12 can be deformed along the thickness direction of the electronic device 100, so that the elastic structure 12 becomes thicker, so as to provide a buffer for the substrate 11 when the substrate 11 is impacted. Since the multiple elastic structures 12 are arranged in gaps, if the substrate 11 is indeed deformed when it is impacted by external forces, it can also be deformed in the area where the gaps of the multiple elastic structures 12 are located, so that there is an area or space to release the internal stress of the substrate 11 when it is subjected to external forces. In addition, the multiple elastic structures 12 are arranged in gaps, so that each elastic structure 12 can deform along the thickness direction of the electronic device 100 (that is, perpendicular to the direction of the substrate 11) and each elastic structure 12 itself has enough deformation space to provide sufficient buffer for the substrate 11. Since the support sheet 10 is used to support the screen assembly 20, the support sheet 10 can provide a longitudinal deformation space and flexible support for the screen assembly 20.

[0059] Please refer to Fig.11 Similarly, due to the gaps between the multiple elastic structures 12, each elastic structure 12 can also undergo lateral deformation along the plane direction of the electronic device 100 (that is, along the plane direction of the substrate 11), so that the support sheet 10 can undergo a slight displacement relative to the screen (that is, a lateral movement). Specifically, when the support sheet is located in the folding area of ​​the foldable electronic device, when the foldable electronic device is folded or unfolded, or when the screen assembly 20 is squeezed by a force F inclined in the direction of the screen assembly 20, the elastic structure 12 can undergo a slight lateral deformation, thereby reducing the internal stress constraint of the support sheet 10 on the screen assembly 20, and avoiding creases or wrinkles in the bending area 221 of the screen assembly 20 due to the inability to release the internal stress concentration.

[0060] Specifically, the force F inclined in the direction of the screen assembly 20 can be orthogonally decomposed into a first force F1 in the vertical direction and a second force F2 in the horizontal direction, wherein the first force F1 can cause the substrate 11 and the elastic structure 12 to deform in the thickness direction of the electronic device 100, and the elastic structure 12 is deformed and thickened to flexibly support the substrate 11 and the screen assembly 20. The second force F2 can cause the substrate 11 and the elastic structure 12 to deform in the horizontal direction of the electronic device, and the substrate 11 can deform along the gap area between the two elastic structures 12 to release its own internal stress. The elastic structure 12 tilts under the force to provide a buffer for the substrate 11. The deformation of the substrate 11 and the buffering of the elastic structure 12 work together to reduce the internal stress constraint of the support sheet 10 on the screen assembly 20, thereby avoiding creases or wrinkles in the bending area 221 of the screen assembly 20 due to the concentration of internal stress that cannot be released.

[0061] In this embodiment, the first surface 111 of the substrate 11 faces the screen assembly 20, and the second surface 20 of the substrate 11 faces the shell assembly 30. A plurality of elastic structures 12 are intermittently arranged on the second surface 112 (no elastic structure 12 is arranged on the first surface). On the one hand, the side of the substrate 111 facing the screen assembly 20 remains flat, so that the bending area of ​​the screen assembly 20 contacts a flat surface during the unfolding or folding process without any uneven protrusions, thereby avoiding the appearance of printed spots on the screen assembly 20. On the other hand, due to the intermittent arrangement of the plurality of elastic structures 12, the internal stress of the screen assembly 20 can be released through the gaps between the elastic structures 12, thereby avoiding creases or wrinkles in the bending area 221 of the screen assembly 20 due to the inability to release the internal stress concentration.

[0062] In other embodiments, the first surface 111 of the substrate 11 faces the screen assembly 20, the second surface 20 of the substrate 11 faces the shell assembly 30, and the multiple elastic structures 12 can also be intermittently arranged on the first surface 111. For example, in the case where the screen assembly 20 is a non-flexible screen, the elastic structure 12 contacts the screen assembly 20 and does not cause a printing point effect on the screen assembly 20. At this time, even if the support sheet 10 and the screen assembly 20 fit the internal stress of the bending of the screen assembly 20, due to the gap arrangement of the multiple elastic structures 12 between the support sheet 10 and the screen assembly 20, the internal stress of the screen assembly 20 can be released through the gap between the elastic structures 12, thereby avoiding the bending area 221 of the screen assembly 20 from generating creases or wrinkles due to the concentration of internal stress that cannot be released. Of course, the first surface 111 of the substrate 11 faces the screen assembly 20, the second surface 20 of the substrate 11 faces the shell assembly 30, and the multiple elastic structures 12 can be intermittently arranged on the first surface 111 and the second surface 112 at the same time.

[0063] Optionally, the thickness of the substrate 11 is between 0.025mm and 0.050mm to minimize the impact of the substrate 11 on the thickness of the electronic device 100 and enable the substrate 11 to be deformed more easily, so as to provide flexible support and deformation space for the screen assembly 20, and bend with the screen assembly 20 (such as a flexible display screen 21 assembly) to reduce bending resistance.

[0064] Optionally, the material of the substrate 11 may be one or more of stainless steel, carbon fiber, polyimide, and polyethylene terephthalate, and no specific limitation is made here. Specifically, the substrate 11 is made of a material with good tensile modulus and bending modulus, so that the substrate 11 has good bending performance and compressive performance, thereby improving the reliability of the electronic device 100.

[0065] Optionally, the elastic structure 12 may be cylindrical, prism-shaped or truncated cone-shaped, etc., and no specific limitation is made here. The height of the elastic structure 12 is approximately twice the thickness of the substrate 11, so that the elastic structure 12 can be sufficiently deformed along the thickness direction of the substrate 11 to provide a buffer for the substrate 11, thereby flexibly supporting the screen assembly 20. Specifically, the height of the elastic structure 12 may be between 0.05-0.10 mm, specifically 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm or 0.10 mm, so that the elastic structure 12 can provide support for the substrate 11 without affecting the thickness of the support sheet 10.

[0066] The width of the elastic structure 12 is between 0.30 mm and 0.70 mm, so that the elastic structure 12 can sensitively provide deformation feedback even when slightly squeezed, thereby improving the buffering performance of the screen assembly 20. Specifically, the width of the elastic structure 12 can be 0.30 mm, 0.40 mm, 0.50 mm, 0.60 mm or 0.70 mm, so that the elastic structure 12 has sufficient contact area with the substrate 11 to effectively support the substrate 11.

[0067] Furthermore, the distance between two adjacent elastic structures 12 is greater than 0.30 mm, such as 0.40 mm, 0.50 mm, and no specific limitation is made here. With such a configuration, on the one hand, when the screen assembly 20 is squeezed, the gap between the elastic structures 12 can provide sufficient deformation space for the deformation of the substrate 11 along its thickness direction, and on the other hand, the gap between the elastic structures 12 can also provide sufficient deformation space for the deformation of the elastic structure 12 along the thickness direction of the substrate 11 (i.e., longitudinal deformation), thereby providing sufficient flexible support for the screen assembly 20. In addition, during the folding and unfolding process of the foldable electronic device, the gaps between the elastic structures 12 can also provide deformation space for the elastic structure 12 to deform along the planar direction of the substrate 11 (i.e., lateral deformation), so that multiple elastic structures 12 can be compressed or stretched. In particular, when the folding screen electronic device is bent, due to the gaps between the multiple elastic structures 12, the substrate 11 and the screen assembly 20 corresponding to the substrate can be deformed in the area corresponding to the gaps between the elastic structures 12, thereby releasing the internal stress in the corresponding area, thereby avoiding creases or wrinkles in the bending area 221 of the screen assembly 20 due to the inability to release the internal stress concentration.

[0068] Optionally, the multiple elastic structures 12 may be distributed in an array, and the spacing between the elastic structures 12 is uniform. That is, the multiple elastic structures 12 are evenly distributed on the first surface 111 and / or the second surface 112, so that the impact force can be evenly shared when the screen assembly 20 is squeezed, thereby improving the impact resistance of the screen assembly 20. In other embodiments, the multiple elastic structures 12 may also be arranged with different gaps and shapes according to the corresponding positions and functions of the screen to meet its actual needs, and no specific limitation is made here.

[0069] Optionally, the elastic structure 12 is made of one or more materials with good elasticity such as silicone, thermoplastic polyurethane elastomer rubber, etc., and no specific limitation is made here.

[0070] The support sheet 10 provided in the embodiment of the present application is provided with a plurality of elastic structures 12 with gaps therein through the first surface 111 and / or the second surface 112 of the substrate 11. On the one hand, the elastic structure 12 can sufficiently deform along the thickness direction of the substrate 11 to provide a buffer for the substrate 11, thereby flexibly supporting the screen assembly 20. On the other hand, the gaps between the elastic structures 12 can provide an area or space for the substrate 11 to deform, so that even if the substrate 11 and the screen assembly 20 are subjected to external force and deformation is indeed required, there is space for deformation to occur, thereby releasing internal stress.

[0071] Please continue to refer to Figure 5 and Figure 6In one embodiment, the electronic device 100 may be a folding screen electronic device, such as a folding screen mobile phone. The screen assembly 20 is a flexible screen assembly, and specifically, the screen assembly 20 may include a stacked flexible display screen 21 and a support plate 22 under the screen, and the support plate 22 under the screen is used to support and protect the flexible display screen 21. The support plate 22 under the screen may include a bending area 221 and a first fixing area 222 and a second fixing area 223 located on both sides of the bending area 221. When the electronic device 100 is in an unfolded state, the bending area 221, the first fixing area 222 and the second fixing area 223 are located on the same plane; when the electronic device 100 is in a folded state, the first fixing area 222 and the second fixing area 223 are parallel or mutually attached. When the electronic device 100 is bent, at least part of the support sheet 10 can be displaced relative to the screen assembly 20 to reduce the stress constraint of the support sheet 10 on the screen assembly 20, avoid creases or wrinkles on the flexible display screen 21 corresponding to the bending area 221, and improve the appearance performance of the electronic device 100.

[0072] Optionally, the material of the under-screen support plate 22 may be a material with good flexibility such as steel sheet or carbon fiber. It can be understood that the bending area 221 of the under-screen support plate 22 is usually evenly provided with a plurality of pressure relief holes (not shown in the figure), which are used to improve the bending performance of the under-screen support plate 22 and facilitate the bending of the under-screen support plate 22 on the one hand, and release the internal stress of the screen assembly 20 when it is bent on the other hand, so as to avoid the under-screen support plate 22 squeezing the flexible display screen 21, so as to cause creases or wrinkles on the surface of the flexible display screen 21.

[0073] The housing assembly 30 may include a hinge structure 31 and a first housing 32 and a second housing 33 connected to two ends of the hinge structure 31 , wherein two ends of the screen assembly 20 are fixed to the first housing 32 and the second housing 33 , respectively.

[0074] Specifically, the rotating shaft structure 31 includes a middle plate 311 and a first connecting plate 312 and a second connecting plate 313 which are respectively rotatably connected to both sides of the middle plate 311, wherein the first connecting plate 312 is rotatably connected to the first shell 32 on the side away from the middle plate 311, and the second connecting plate 313 is rotatably connected to the second shell 33 on the side away from the middle plate 311. The first fixing area 222 is fixed to the first shell 32, the second fixing area 223 is fixed to the second shell 33, and the bending area 221 corresponds to and fits the rotating shaft structure 31, that is, the bending area 221 corresponds to the first connecting plate 312, the middle plate 311 and the second connecting plate 313. In other words, the first fixing area 222 corresponds to and is fixed to the first shell 32, the second fixing area 223 corresponds to and is fixed to the second shell 33, and the bending area 221 is arranged corresponding to the rotating shaft structure 31.

[0075] In one embodiment, the support sheet 10 may be located between the hinge structure 31 and the screen assembly 20, and part of the support sheet 10 is fixed to the screen assembly 20. When the screen assembly 20 is bent, part of the support sheet 10 is fixed to the under-screen support plate 22, and the other part (that is, the part of the support sheet 10 that is not fixed to the under-screen support plate 22) may be displaced relative to the support sheet 10, so as to avoid stress constraint of the support sheet 10 on the under-screen support plate 22 when the support sheet 10 and the under-screen support plate 22 are completely overlapped, so as to provide sufficient space for the bending deformation of the under-screen support plate 22, thereby reducing the local internal stress of the screen assembly 20 when the screen assembly 20 is bent.

[0076] Please refer to Figure 5 as well as Figures 12 to 17 , Fig.12 yes Figure 5 A cross-sectional schematic diagram of an embodiment of an electronic device is shown, Fig.13 yes Fig.12 A deformed cross-sectional schematic diagram of an electronic device is shown. Fig.14 yes Figure 5 A cross-sectional schematic diagram of another embodiment of an electronic device is shown, Fig.15 yes Fig.14 A deformed cross-sectional schematic diagram of an electronic device is shown. Fig.16 yes Figure 5 A cross-sectional schematic diagram of another embodiment of an electronic device is shown, Fig.17 yes Fig.16 A schematic cross-sectional view of a deformation of an electronic device shown. In a specific embodiment, the support sheet 10 may include a first support sheet 101 and a second support sheet 102 that are spaced apart. The first support sheet 101 includes a first support portion 1011, the first support portion 1011 corresponds to and covers the first connecting plate 312 and a portion of the middle plate 311, and the first support portion 1011 is used to flexibly support the screen assembly 20 corresponding to the portion of the bending area 221. The second support sheet 102 includes a second support portion 1021 that corresponds to and covers the second connecting plate 313 and a portion of the middle plate 311 (that is, the middle plate 311 away from the first support portion 1011), and the second support portion 1021 is used to flexibly support the screen assembly 20 corresponding to another portion of the bending area 221. That is, the first support sheet 101 and the second support sheet 102 are located within the range of the bending zone 221. On the one hand, they are used to flexibly support the screen assembly 20 corresponding to the bending zone 221, and on the other hand, they can provide deformation space for the screen assembly 20 along the planar direction, thereby avoiding creases or wrinkles on the flexible display screen 21 corresponding to the bending zone 221.

[0077] The electronic device 100 may further include a first adhesive portion 40, which may be located between the first support portion 1011 and the under-screen support plate 22 (i.e., the screen assembly 20) to fix the first support sheet 101 to the screen assembly 20. The first adhesive portion 40 may also be located between the second support portion 1021 and the under-screen support plate 22 (i.e., the screen assembly 20) to fix the second support sheet 102 to the screen assembly 20. It can be understood that since the first support sheet 101 and the second support sheet 102 are arranged at intervals, when the electronic device 100 is bent, the first support sheet 101 and the second support sheet 102 can flexibly support the screen assembly 20 without increasing the internal stress of the bending area 221 of the screen assembly 20, so as to avoid creases or wrinkles on the flexible display screen 21 corresponding to the bending area 221, thereby improving the appearance performance of the electronic device 100.

[0078] Furthermore, part of the first support portion 1011 is fixed to the bending area 221 of the under-screen support plate 22 (that is, the screen assembly 20) through the first adhesive portion 40, and another part of the first support portion 1011 is spaced from the under-screen support plate 22 (such as Fig.12 or Fig.14 As shown). Through the above-mentioned method, when the electronic device 100 is bent, the part of the first support sheet 101 away from the first glue part 40 can move relative to the support plate 22 under the screen, thereby reducing the constraint of the first support sheet 101 on the bending area 221, and facilitating the release of stress in the screen assembly 20. Specifically, one end of the first support part 1011 corresponding to the middle plate 311 can be fixed to the support plate 22 under the screen, or one end of the first support part 1011 corresponding to the first connecting plate 312 can be fixed to the support plate 22 under the screen, and no specific restrictions are made here. Alternatively, the first support part 1011 is completely fitted with the support plate 22 under the screen through the first glue part 40, and the second support part 1021 is completely fitted with the support plate 22 under the screen through the first glue part 40, and no specific restrictions are made here.

[0079] Similarly, part of the second support part 1021 is fixed to the bending area 221 of the under-screen support plate 22 through the first glue part 40, and the other part of the second support part 1021 is set with a gap between the under-screen support plate 22. In this way, when the electronic device 100 is bent, the part of the second support part 1021 away from the first glue part 40 can move relative to the under-screen support plate 22, reducing the constraint of the second support sheet 102 on the bending area 221, and facilitating the release of stress in the screen assembly 20. Specifically, one end of the second support part 1021 corresponding to the middle plate 311 can be fixed to the under-screen support plate 22, or one end of the second support part 1021 corresponding to the second connecting plate 313 can be fixed to the under-screen support plate 22, and no specific limitation is made here. That is, at least part of the first support part 1011 is connected to the screen assembly 20, and at least part of the second support part 1021 is connected to the screen assembly 20.

[0080] Optionally, based on the above embodiment, the electronic device 100 may further include a second adhesive portion 50, which may be located between the first support portion 1011 and the hinge structure 31, so as to fix the first support sheet 101 to the hinge structure 31. The second adhesive portion 50 may also be located between the second support portion 1021 and the hinge structure 31, so as to fix the second support sheet 102 to the hinge structure 31. The support sheet 10 is fixed to the screen assembly 20 through the first adhesive portion 40 and to the hinge structure 31 through the second adhesive portion 50, so as to improve the reliability of the connection between the screen assembly 20 and the housing assembly 30.

[0081] It can be understood that the second glue part 50 can be symmetrically arranged with the first glue part 40 about the first support part 1011 or the second support part 1021. On the one hand, it is used to improve the reliability of the connection between the screen assembly 20 and the shell assembly 30. On the other hand, it enables the part of the first support sheet 101 away from the first glue and the part of the second support sheet 102 away from the first glue part 40 to be displaced relative to the under-screen support plate 22, so as to provide sufficient buffer space for the bending of the screen assembly 20 and reduce the stress constraint of the support sheet 10 on the screen assembly 20.

[0082] Specifically, when one end of the first support sheet 101 corresponding to the middle plate 311 is fixed to the under-screen support plate 22 through the first adhesive portion 40, the second adhesive portion 50 is located on the middle plate 311 (eg Fig.15 and / or, when one end of the first support sheet 101 corresponding to the first connecting plate 312 is fixed to the under-screen support plate 22 through the first adhesive portion 40, the second adhesive portion 50 is located on the first connecting plate 312 (such as Fig.13 or Fig.17 ). Similarly, when one end of the second support sheet 102 corresponding to the middle plate 311 is fixed to the under-screen support plate 22 through the first glue portion 40, the second glue portion 50 is located on the middle plate 311; and / or, when one end of the second support sheet 102 corresponding to the second connecting plate 313 is fixed to the under-screen support plate 22 through the first glue portion 40, the second glue portion 50 is located on the second connecting plate 313. That is, at least part of the first support portion 1011 is fixed to the middle plate 311 and / or the first connecting plate 312 through the second glue portion 50, and at least part of the second support portion 1021 is fixed to the middle plate 311 and / or the second connecting plate 313 through the second glue portion 50. That is, at least part of the first support portion 1011 is connected to the first connecting plate 312 and part of the middle plate 311 covered by the first support portion 1011, and at least part of the second support portion 1021 is connected to the second connecting plate 313 and part of the middle plate 311 covered by the second support portion 1021.

[0083] In summary, the support sheet 10 includes a first support sheet 101 and a second support sheet 102 that are spaced apart, the first support sheet 101 includes a first support portion 1011 that covers the first connecting plate 312 and a portion of the middle plate 311, and the second support sheet 102 includes a second support portion 1021 that covers the second connecting plate 313 and a portion of the middle plate 311, wherein the first support portion 1011 and the second support sheet together provide flexible support for the screen assembly 20 corresponding to the hinge structure 31. At least part of the first support portion 1011 is connected to the screen assembly 20 and / or the first connecting plate 312 and a portion of the middle plate 311 covered by the first support portion 1011, and at least part of the second support portion 1021 is connected to the screen assembly 20 and / or the second connecting plate 313 and a portion of the middle plate 311 covered by the second support portion 2021.

[0089] The electronic device 100 includes a third adhesive portion 60, and the first extension portion 1012 is fixed to the screen assembly 20 through the third adhesive portion 60, so that the first support portion 1011 can be displaced relative to the screen assembly 20, so as to provide sufficient space for the bending of the screen assembly 20 and reduce the stress constraint of the support sheet 10 on the screen assembly 20. Similarly, the second extension portion 1022 is fixed to the screen assembly 20 through the third adhesive portion 60, so that the second support portion 1021 can be displaced relative to the screen assembly 20, so as to provide sufficient space for the bending of the screen assembly 20 and reduce the stress constraint of the support sheet 10 on the screen assembly 20 (such as Fig. 20 shown).

[0090] And / or, the electronic device further includes a second adhesive portion 50, and the first extension portion 1012 is fixed to the first shell 32 through the second adhesive portion 50, so that on the one hand, the first extension portion 1012 is fixed to the first shell 32 and flexibly supports the screen assembly 20 corresponding to the first shell 32, and on the other hand, the first support portion 1011 can be displaced relative to the screen assembly 20 to provide sufficient space for the bending of the screen assembly 20 and reduce the stress constraint of the support sheet 10 on the screen assembly 20.

[0093] Fig.23 yes Fig. 22A schematic cross-sectional view of a deformation of an electronic device shown. In another specific embodiment, the support sheet 10 may include a first support sheet 101 and a second support sheet 102 arranged at intervals. The first support sheet 101 includes a first support portion 1011, the first support portion 1011 corresponds to and covers the first connecting plate 312 and a portion of the middle plate 311, and the first support portion 1011 is used to flexibly support the screen assembly 20 corresponding to the portion of the bending area 221. The second support sheet 102 corresponds to and covers the second connecting plate 313 and a portion of the middle plate 311 (that is, the middle plate 311 away from the first support portion 1011), and the second support portion 1021 is used to flexibly support the screen assembly 20 corresponding to another portion of the bending area 221. That is, the first support sheet 101 and the second support sheet 102 are located within the range of the bending zone 221. On the one hand, they are used to flexibly support the screen assembly 20 corresponding to the bending zone 221, and on the other hand, they can provide a deformation space for the screen assembly 20, so that the internal stress of the screen assembly 20 in the bending zone 221 can be released, thereby avoiding creases or wrinkles on the flexible display screen 21 corresponding to the bending zone 221.

[0094] The electronic device 100 may include a second adhesive portion 50, which may be located between the first support sheet 101 and the shell assembly 30 to fix the first support sheet 101 and the shell assembly 30; the second adhesive portion 50 may also be located between the second support sheet 102 and the shell assembly 30 to fix the second support sheet 102 and the shell assembly 30.

[0095] The first support portion 1011 can be fixedly connected to at least one of the middle plate 311 and the first connecting plate 312 through the second adhesive portion 50, and / or the first extension portion 1012 can be fixedly connected to the first shell 32 through the second adhesive portion 50, so that the first support sheet 101 can be bent along with the shell assembly 30, and the first support sheet 101 can be displaced as a whole relative to the screen assembly 20 to provide sufficient buffer space for the bending of the screen assembly 20 without increasing the internal stress of the bending zone 221, so as to avoid creases or wrinkles on the flexible display screen 21 corresponding to the bending zone 221, thereby improving the appearance performance of the electronic device 100. The second support portion 1021 may be fixedly connected to at least one of the middle plate 311 and the second connecting plate 313 through the second adhesive portion 50, and / or the second extension portion 1022 may be fixedly connected to the second shell 33 through the second adhesive portion 50, so that the second support sheet 102 can be bent along with the shell assembly 30, and the second support sheet 102 may be displaced as a whole relative to the screen assembly 20, so as to provide sufficient buffer space for the bending of the screen assembly 20 without increasing the internal stress of the bending area 221, so as to avoid creases or wrinkles on the flexible display screen 21 corresponding to the bending area 221, thereby improving the appearance performance of the electronic device 100 (such as Fig. 22 shown).

[0096] Further, the first support sheet 101 may further include a first extension portion 1012, the first extension portion 1012 corresponds to and covers at least a portion of the first shell 32, and the first extension portion 1012 may be used to flexibly support the first fixed area 222.

[0097] The first support sheet 101 can be fixedly connected to one or more of the middle plate 311, the first connecting plate 312 and the first shell 32 through the second adhesive portion 50, and the first support sheet 101 can be bent along with the shell assembly 30. The first support sheet 101 can be displaced as a whole relative to the screen assembly 20 to provide sufficient buffer space for the bending of the screen assembly 20 without increasing the internal stress of the bending zone 221, so as to avoid creases or wrinkles on the flexible display screen 21 corresponding to the bending zone 221, thereby improving the appearance performance of the electronic device 100.

[0098] Similarly, the second support sheet 102 can be fixedly connected to one or more of the middle plate 311, the second connecting plate 313 and the second shell 33 through the second adhesive portion 50, so that the second support sheet 102 can be bent along with the shell assembly 30, and the second support sheet 102 can be displaced as a whole relative to the screen assembly 20 to provide sufficient buffer space for the bending of the screen assembly 20 without increasing the internal stress of the bending zone 221, so as to avoid creases or wrinkles on the flexible display screen 21 corresponding to the bending zone 221, thereby improving the appearance performance of the electronic device 100 (such as Fig.23 shown).

[0099] That is, the first support sheet 101 is connected to the first housing 32 and / or the hinge structure 31, and a gap is set between the first support sheet 101 and the screen assembly 20, so that the first support sheet 101 can be displaced relative to the screen assembly 20; the second support sheet 102 is connected to the second housing 33 and / or the hinge structure 31, and a gap is set between the second support sheet 102 and the screen assembly 20, so that the second support sheet 102 can be displaced relative to the screen assembly 20. In the above manner, the support sheet 10 can bend the screen assembly 20 and provide sufficient buffer space without increasing the internal stress of the bending area 221, so as to avoid creases or wrinkles on the flexible display screen 21 corresponding to the bending area 221, thereby improving the appearance performance of the electronic device 100.

[0100] Please refer to Figure 5 as well as Figure 24 to Figure 27 middle, Fig.24 yes Figure 5 The cross-sectional schematic diagram of another embodiment of the electronic device shown is Fig.25 yes Fig.24A deformed cross-sectional schematic diagram of an electronic device is shown. Fig.26 yes Fig.25 A schematic cross-sectional view of a deformation of the electronic device, Fig. 27 yes Fig.26 A cross-sectional schematic diagram of a deformation of the electronic device shown. In another embodiment, the support sheet 10 may include a main board portion 103, and the main board portion 103 corresponds to and covers the first connecting plate 312, the middle plate 311 and the second connecting plate 313, that is, the main board portion 103 is arranged corresponding to the hinge structure 31. Since a plurality of elastic structures 12 are provided on the support sheet 10, the support sheet 10 can flexibly and elastically support the bending area 221 of the screen assembly 20, and can provide a certain buffer space for the screen assembly 20.

[0101] The electronic device 100 further includes a first adhesive portion 40 , through which the main board portion 103 is fixed to the screen assembly 20 , and a projection of the first adhesive portion 40 on the support sheet 10 is located within the range of at least one of the first connecting plate 312 , the middle plate 311 and the second connecting plate 313 .

[0102] Specifically, take the projection of the first adhesive portion 40 on the support sheet 10 being within the range of the first connecting plate 312 as an example (eg Fig.25 As shown), when the electronic device 100 is folded, the support sheet 10 can bend along with the bending of the electronic device 100. Since one end of the support sheet 10 is fixed to the area of ​​the screen assembly 20 corresponding to the first connecting plate 312, the end of the support sheet 10 away from the first adhesive portion 40 can be displaced relative to the screen assembly 20. In the above manner, on the one hand, the internal stress generated by the bending of the main board portion 103 does not need to be transmitted to the screen assembly 20, thereby avoiding the stress constraint of the support sheet 10 on the under-screen support plate 22 when the support sheet 10 and the under-screen support plate 22 are completely overlapped. On the other hand, the relative movement of the support sheet 10 relative to the screen assembly 20 can provide a certain buffer space for the bending of the screen assembly 20, thereby reducing the local internal stress when the screen assembly 20 is bent. Similarly, in other embodiments, the projection of the first adhesive portion 40 on the support sheet 10 is located within the range of the second connecting plate 313.

[0103] In another embodiment, the projection of the first adhesive portion 40 on the support sheet 10 is located within the range of the middle plate 311 (eg Fig.26As shown). It can be understood that the first adhesive portion 40 is located in the middle of the main board portion 103. In other words, the middle area of ​​the main board portion 103 is fixed to the screen assembly 20 through the first adhesive portion 40, and the two ends of the main board portion 103 are spaced apart from the screen assembly 20. When the electronic device 100 is bent, the two ends of the main board portion 103 can be displaced relative to the screen assembly 20 at the same time. On the one hand, the support sheet 10 can be prevented from transmitting stress to the screen assembly 20. On the other hand, the support sheet 10 can move relative to the screen assembly 20, which can provide a certain buffer space for the bending of the screen assembly 20, thereby preventing the flexible display screen 21 corresponding to the bending area 221 from generating creases or wrinkles.

[0104] In other embodiments, the projection of the first adhesive portion 40 on the support sheet 10 can also be located within the range of the first connecting plate 312 and the middle plate 311 at the same time. Specifically, the first adhesive portion 40 is roughly strip-shaped and there are two of them, and the projection area of ​​one first adhesive portion 40 on the first connecting plate 312 is smaller than the area of ​​the first connecting plate 312, and the projection area of ​​the other first adhesive portion 40 on the middle plate 311 is smaller than the area of ​​the middle plate 311. On the one hand, the support sheet 10 and the screen assembly 20 are fixed, and on the other hand, only the internal stress of the area of ​​the support sheet 10 corresponding to the first adhesive portion 40 is constrained, so that the internal stress of the screen assembly 20 can be released through the area of ​​the support sheet 10 away from the first adhesive portion 40. In addition, the area of ​​the support sheet 10 away from the first adhesive portion 40 can be displaced relative to the screen assembly 20, which can provide a certain buffer space for the bending of the screen assembly 20, thereby reducing the local internal stress of the screen assembly 20 when it is bent. Similarly, the projection of the first adhesive portion 40 on the support sheet 10 can also be located within the range of the second connecting plate 313 and the middle plate 311 at the same time. Specifically, the first adhesive portion 40 is roughly strip-shaped and there are two of them, and the projection area of ​​one first adhesive portion 40 on the first connecting plate 312 is smaller than the area of ​​the second connecting plate 313 , and the projection area of ​​the first adhesive portion 40 on the middle plate 311 is smaller than the area of ​​the middle plate 311 .

[0105] Alternatively, the projection of the first adhesive portion 40 on the support sheet 10 may also be simultaneously located on the first connecting plate 312, the middle plate 311, and the second connecting plate 313. Specifically, the first adhesive portion 40 is roughly strip-shaped and there are three of them, and the projection area of ​​one first adhesive portion 40 on the first connecting plate 312 is smaller than the area of ​​the first connecting plate 312, the projection area of ​​another first adhesive portion 40 on the middle plate 311 is smaller than the area of ​​the middle plate 311, and the projection area of ​​the remaining first adhesive portion 40 on the first connecting plate 312 is smaller than the area of ​​the second connecting plate 313. On the one hand, the support sheet 10 and the screen assembly 20 are fixed, and on the other hand, only the internal stress of the support sheet 10 corresponding to the first adhesive portion 40 is constrained, so that the internal stress of the screen assembly 20 can be released through the area of ​​the support sheet 10 away from the first adhesive portion 40.

[0106] That is, the main board portion 103 is fixed to the screen assembly 20 through the first adhesive portion 40, and the projection of the first adhesive portion 40 on the support sheet 10 is located within the range of at least one of the first connecting plate 312, the middle plate 311, and the second connecting plate 313. In other words, the projection of the area where the main board portion 103 connects to the screen assembly 20 on the support sheet 10 is located within the range of at least one of the first connecting plate 312, the middle plate 311, and the second connecting plate 313.

[0107] Furthermore, the electronic device 100 may further include a second adhesive portion 50, and the mainboard portion 103 is fixedly connected to the hinge structure 31 through the second adhesive portion 50, and the second adhesive portion 50 and the first adhesive portion 40 are symmetrical about the mainboard portion 103. The support sheet 10 is fixed to the screen assembly 20 through the first adhesive portion 40 and to the hinge structure 31 through the second adhesive portion 50, so as to improve the reliability of the connection between the screen assembly 20 and the housing assembly 30.

[0108] In a specific embodiment, the second adhesive portion 50 may be located between the first connecting plate 312 and the main board portion 103, and correspondingly, the first adhesive portion 40 is located between the main board portion 103 and the screen assembly 20 and the first adhesive portion 40 is located within the range of the main board portion 103 corresponding to the first connecting plate 312. One end of the main board portion 103 is fixed to the screen assembly 20 and the first connecting plate 312 at the same time, so as to improve the reliability of the connection between the main board portion 103 and the electronic device 100; one end of the main board portion 103 away from the first adhesive portion 40 is provided with a gap between the screen assembly 20 and the hinge structure 31 at the same time, so that when the electronic device 100 is bent, the end of the main board portion 103 away from the first adhesive portion 40 can be displaced relative to the screen assembly 20, so as to provide space for the deformation of the screen assembly 20, reduce the stress constraint of the support sheet 10 on the screen assembly 20, avoid creases or wrinkles on the flexible display screen 21 corresponding to the bending zone 221, and improve the appearance performance of the electronic device 100.

[0109] Similarly, in a specific embodiment, the second adhesive portion 50 may also be located between the second connecting plate 313 and the main board portion 103, and correspondingly, the first adhesive portion 40 is located between the main board portion 103 and the screen assembly 20, and the first adhesive portion 40 is located within the range of the main board portion 103 corresponding to the second connecting plate 313. Alternatively, the second adhesive portion 50 may also be located between the middle plate 311 and the main board portion 103, and correspondingly, the first adhesive portion 40 is located between the main board portion 103 and the screen assembly 20, and the first adhesive portion 40 is located within the range of the main board portion 103 corresponding to the middle plate 311 (e.g., Fig. 27 shown).

[0110] That is, the main board portion 103 is also connected to at least one of the first connecting plate 312, the middle plate 311 and the second connecting plate 313 through the second adhesive portion 50. In other words, the main board portion 103 can be connected to at least one of the first connecting plate 312, the middle plate 311 and the second connecting plate 313.

[0111] In summary, the support sheet 10 includes a main board portion 103 covering the first connecting plate 312, the middle plate 311 and the second connecting plate 313; the main board portion 103 is connected to the screen assembly 20, and the projection of the area of ​​the main board portion 103 connected to the screen assembly 20 on the support sheet 10 is located within the range of at least one of the first connecting plate 312, the middle plate 311 and the second connecting plate 313; and / or the main board portion 103 is connected to at least one of the first connecting plate 312, the middle plate 311 and the second connecting plate 313.

In another embodiment, based on the above embodiment, the support sheet 10 may further include a main board portion 103 and a first connection portion 104 and a second connection portion 105 respectively located on both sides of the main board portion 103, the first connection portion 104 covers at least a portion of the first shell 32, and is used to flexibly support the screen assembly 20 corresponding to the first connection plate 312; the second connection portion 105 covers at least a portion of the second shell 33, and is used to flexibly support the screen assembly 20 corresponding to the second shell 33.

[0113] The electronic device 100 further includes a third adhesive portion 60 , and the first connection portion 104 may be fixed to the first housing 32 via the third adhesive portion 60 , and / or the second connection portion 105 may be fixed to the second housing 33 via the third adhesive portion 60 .

[0114] Specifically, when the projection of the first adhesive portion 40 on the support sheet 10 is located within the range of the first connecting plate 312, the first connecting portion 104 is fixed to the first shell 32 through the third adhesive portion 60, which improves the reliability of the connection between the support sheet 10 and the screen assembly 20 on the one hand, and allows the end of the support sheet 10 away from the first connecting portion 104 to be displaced relative to the screen assembly 20 on the other hand. Alternatively, when the projection of the first adhesive portion 40 on the support sheet 10 is located on the second connecting plate 313, the second connecting portion 105 is fixed to the second shell 33 through the third adhesive portion 60, which improves the reliability of the connection between the support sheet 10 and the screen assembly 20 on the one hand, and allows the end of the support sheet 10 away from the first connecting portion 104 to be displaced relative to the screen assembly 20 on the other hand.

In another embodiment, the support sheet 10 may include a main board portion 103, and the main board portion 103 corresponds to and covers the first connecting plate 312, the middle plate 311 and the second connecting plate 313, that is, the main board portion 103 is arranged corresponding to the hinge structure 31. Since a plurality of elastic structures 12 are provided on the support sheet 10, the support sheet 10 can flexibly and elastically support the bending area 221 of the screen assembly 20, and can provide a certain buffer space for the screen assembly 20.

[0116] The electronic device 100 further includes a second adhesive portion 50, and the main board portion 103 is fixed to the hinge structure 31 through the second adhesive portion 50. Specifically, the main board portion 103 is fixedly connected to at least one of the first connecting plate 312, the middle plate 311, and the second connecting plate 313 through the second adhesive portion 50, so as to fix the support sheet 10 to the hinge structure 31.

[0117] It can be understood that since the support sheet 10 is only fixed to the hinge structure 31, when the electronic device 100 is bent, the support sheet 10 can not only bend with the shell assembly 30 and undergo elastic deformation, but can also displace relative to the screen assembly 20, so as to provide sufficient buffer space for the screen assembly 20 to bend, without increasing the internal stress of the bending zone 221, so as to avoid creases or wrinkles on the flexible display screen 21 corresponding to the bending zone 221, thereby improving the appearance performance of the electronic device 100.

[0118] Please refer to Fig.31 , Fig.31 yes Fig.28 Another deformed cross-sectional schematic diagram of the electronic device shown. In another embodiment, the support sheet 10 may also include a main board portion 103 and a first connecting plate 312 and a second connecting plate 313 respectively located on both sides of the main board portion 103. The main board portion 103 covers the first connecting plate 312, the middle plate 311 and the second connecting plate 313, and is used to flexibly support the screen assembly 20 corresponding to the first connecting plate 312, the middle plate 311 and the second connecting plate 313; the first connecting plate 312 covers at least a portion of the first shell 32, and is used to flexibly support the screen assembly 20 corresponding to the first connecting plate 312; the second connecting portion 105 covers at least a portion of the second shell 33, and is used to flexibly support the screen assembly 20 corresponding to the second shell 33. Since a plurality of elastic structures 12 are provided on the support sheet 10, the support sheet 10 can flexibly and elastically support the bending area 221 of the screen assembly 20, and can provide a certain buffer space for the screen assembly 20.

[0119] The electronic device 100 further includes a second adhesive portion 50, and the main board portion 103 is fixed to the hinge structure 31 through the second adhesive portion 50. Specifically, the support sheet 10 is fixedly connected to at least one of the first housing 32, the first connecting plate 312, the middle plate 311, the second connecting plate 313, and the second housing 33 through the second adhesive portion 50, so as to fix the support sheet 10 to the hinge structure 31.

[0120] It can be understood that since the support sheet 10 is fixed to the shell assembly 30, when the electronic device 100 is bent, the support sheet 10 can not only bend with the shell assembly 30 and undergo elastic deformation, but can also displace relative to the screen assembly 20, so as to provide sufficient buffer space for the screen assembly 20 to bend, without increasing the internal stress of the bending zone 221, so as to avoid creases or wrinkles on the flexible display screen 21 corresponding to the bending zone 221, thereby improving the appearance performance of the electronic device 100.

[0121] That is, the support sheet 10 also includes a first connecting portion 104 and a second connecting portion 105 located on both sides of the main board portion 103, the first connecting portion 104 covers at least a portion of the first shell 32, and the second connecting portion 105 covers at least a portion of the second shell 33; the first connecting portion 104 is connected to the screen assembly 20 and / or the first shell 32, and the second connecting portion 105 is connected to the screen assembly 20 and / or the second shell 33.

[0122] In another embodiment, the electronic device 100 may also be a straight electronic device 100 or a pull-out screen electronic device 100. When the electronic device 100 is a straight electronic device 100, the support sheet 10 may be directly located between the screen assembly 20 and the housing assembly 30. In other words, the support sheet 10 does not need to be bonded and fixed to the screen assembly 20 and / or the housing assembly 30, and the thickness of the electronic device 100 is reduced without affecting the reliability of the electronic device 100. When the electronic device 100 is a pull-out screen electronic device 100, the support sheet 10 may be fixed to the housing assembly 30, so that the screen assembly 20 can be displaced relative to the support sheet 10, thereby achieving flexible support for the screen assembly 20.

[0123] The electronic device 100 provided in the embodiment of the present application is configured such that a support sheet 10 is disposed between the screen assembly 20 and the shell assembly 30, and a plurality of elastic structures 12 with gaps are disposed on the first surface 111 and / or the second surface 112 of the substrate 11. On the one hand, the elastic structure 12 can sufficiently deform along the thickness direction of the substrate 11 to provide a buffer for the substrate 11, thereby flexibly supporting the screen assembly 20. On the other hand, the gaps between the elastic structures 12 can provide an area or space for the substrate 11 to deform, so that even if the substrate 11 and the screen assembly 20 are subjected to external force and need to be deformed, they still have space to deform and release internal stress.
