[0041] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0042] In the related art, when designing a folding screen electronic device, considering that the screen may move when folded, a screen pressure bar is usually used to connect it to fix and protect the screen.

[0043] However, this structure requires a wider screen pressure strip to be set at the folding edge, with one end of the screen pressure strip connected to the display module and the other end connected to the upper surface of the middle frame. The height of the screen pressure strip itself increases the thickness of the entire electronic device, which is inconsistent with the current trend of electronic devices to be thinner and lighter, and will also affect the appearance of the entire device and user experience. For example, in the related art, a screen pressure strip is often set at the edge of the screen of a foldable electronic device to prevent the screen from moving when folded, but because the screen pressure strip is located above the screen, it will increase the thickness of the stacked mobile phones, affecting the appearance and user experience.

[0044] In order to solve the above technical problems, an electronic device 1 is provided according to an embodiment of the present disclosure. The electronic device 1 includes: a hinge structure. A screen 2 includes a flexible screen covered on the hinge structure. A middle frame 3 includes a side edge 33 and a screen back fixing portion 7, wherein the side edge 33 is used to fix the edge of the screen 2, and the screen back fixing portion 7 is used to fix the back 25 of the screen 2 opposite to the display surface 23.

[0045] The present invention fixes the screen 2 to the middle frame 3 by connecting the side edge 33 of the middle frame 3 and the fixing portion 33 on the back of the screen to the edge and the back 25 of the screen 2 respectively, thereby avoiding increasing the thickness of the electronic device 1 in the thickness direction and facilitating the realization of lightness and thinness.

[0046] Figure 1 It is a schematic structural diagram of an electronic device 1 according to an exemplary embodiment. Figure 2 It is a schematic structural diagram of an electronic device 1 according to an exemplary embodiment. Figure 8 According to yet another exemplary embodiment Figure 2 Schematic diagram of the structure of part C cut along line A-A'.

[0047] In some embodiments, Figure 1 , Figure 2 or Figure 8 As shown, the electronic device 1 mainly includes a hinge structure (not shown in the figure), a screen 2, a middle frame 3 and a fixing portion 7 on the back of the screen.

[0048] The screen 2 includes a flexible screen covering the hinge structure. For example, the flexible screen may be a flexible liquid crystal display panel (LCD) panel, a flexible organic light-emitting semiconductor (OLED) panel, etc., but the present disclosure does not specifically limit the type of the flexible screen, that is, those skilled in the art can adjust the type according to actual conditions, as long as the flexible screen can display image information and can be deformed.

[0049] like Figure 1 or Figure 2 As shown, the screen 2 may include a bending portion 21 and a non-bending portion 22. The non-bending portion 22 may be bent relative to the bending portion 21.

[0050] It can be understood that the electronic device 1 involved in the present disclosure realizes folding and unfolding through a hinge structure. The bending portion 21 may refer to a part of the screen 2, which can be bent by folding, so as to realize the folding function of the electronic device 1. The non-bending portion 22 may not have the ability to bend, and may be fixed on the middle frame 3. The difference between the bending portion 21 and the non-bending portion 22 is that the bending portion 21 can be bent, while the non-bending portion 22 may not be bent. When the screen 2 is folded, the bending portion 21 undergoes bending deformation, and the non-bending portion 22 remains in its original state.

[0051] Those skilled in the art should understand that the bending portion 21 and the non-bending portion 22 can be used to realize different forms of the electronic device 1 and the screen 2 in the folded and unfolded states. In the folded state, the bending portion 21 can be bent. In the unfolded state, the bending portion 21 can be stretched out to form a complete screen together with the non-bending portion 22, providing better visual effects and user experience.

[0052] In this embodiment, the electronic device 1 further includes a wrapping portion 4, which wraps at least part of the edge of the screen 2 and adheres and fixes the edge of the screen 2 to the side 33 of the middle frame 3, so that the screen 2 and the middle frame 3 can be relatively fixed, and the wrapping portion 4 can also play a role in sealing and protection. Compared with the screen pressing strip covering the upper surface of the middle frame 3 in the related art, the wrapping portion 4 in this embodiment only covers part of the edge of the screen 2 and the gap between the screen 2 and the side 33 of the middle frame 3, and does not need to cover the upper surface of the middle frame 3, thereby reducing the overall stacking thickness of the electronic device 1.

[0053] For example, in some embodiments, the wrapping portion 4 may be made of a colloid material, such as any one or more of UV light curing adhesive, hot melt adhesive, transparent epoxy adhesive, optical grade silicone, and optical grade polycarbonate.

[0054] In the present disclosure, the wrapping portion 4 may be formed by integral injection molding or integral glue injection.

[0055] In this embodiment, since UV light-curing glue, hot melt glue, transparent epoxy glue, optical grade silicone and optical grade polycarbonate all have plastic properties, they can be formed into the desired shape through injection molding. At the same time, these materials can remain liquid at room temperature, which is convenient for injection. After curing or cooling, they can form solids with a certain mechanical strength, so that they can be physically connected to the screen 2. In addition, these materials also have excellent optical properties and will not affect the image display effect after use.

[0056] In some embodiments, the screen 2 includes a display area and a frame area, and the wrapping portion 4 wraps the frame area. Figure 3 According to an exemplary embodiment Figure 2 Schematic diagram of the structure of part B cut along line A-A'. Figure 4 According to an exemplary embodiment Figure 2 The schematic diagram of the structure of the C part cut along the A-A' line in FIG. Figure 3 and Figure 4 As shown, in the present disclosure, the screen 2 may include a display surface 23, a side surface 24 intersecting the display surface 23, and a back surface 25 opposite to the display surface 23. The display surface 23 may include a display area for displaying a picture, and a non-display area surrounding the display area, i.e., a frame area. The frame area may generally be a wiring area, and the frame area may be located at the edge of the display surface 23.

[0057] In some embodiments, the wrapping portion 4 may cover the side surface 24 of the screen 2 and the frame area of ​​the display surface 23 .

[0058] In some embodiments, at least a portion of the wrapping portion 4 extends from the side edge 33 to the display surface 23 of the screen 2. For example, the screen 2 may be disposed on the middle frame 3, and there may be a gap between the screen 2 and the middle frame 3. Figure 3 or Figure 4 As shown, the wrapping portion 4 may include a first portion 41 and a second portion 42 adjacent to each other, and the first portion 41 may cover at least a portion of the display surface 23. For example, the first portion 41 may cover the frame area. The second portion 42 may cover the gap, the first portion 41 may be connected to the screen 2, and the second portion 42 may be connected to the inner side of the middle frame 3.

[0059] In this embodiment, the screen 2 and the middle frame 3 can be relatively fixed by covering the wrapping part 4 on the display surface 23 and the gap, and the wrapping part 4 can also play a role of sealing protection. Compared with the screen pressing strip covering the upper surface of the middle frame in the related art, the wrapping part 4 in this embodiment only covers a part of the display surface 23 and the gap between the screen 2 and the middle frame 3, and does not need to cover the upper surface of the middle frame 3, so that the overall stacking thickness of the electronic device 1 can be reduced. This wrapping part 4 structure that is only set on the display surface 23 and the gap is more in line with the current development trend of electronic devices to be thinner and lighter and to increase the screen-to-body ratio, and can optimize the overall appearance of the electronic device and enhance the user experience.

[0060] In the present disclosure, the display surface 23 of the screen 2 may be a side that displays images. Those skilled in the art should understand that, in the bendable screen 2, both the bending portion 21 and the non-bending portion 22 have a side that can display images.

[0061] In the present disclosure, the wrapping portion 4 can be configured to cover the display surface of the non-bending portion 22 and avoid the display surface of the bending portion 21. Such a configuration can further reduce the thickness of the electronic device when it is in a folded state. In addition, during the folding process of the electronic device, the bending portion generally requires a certain amount of free space to complete folding and bending. The wrapping portion 4 avoids the display surface of the bending portion and does not cover the display surface of the bending portion, thereby achieving the requirement of providing a certain amount of free space for the bending portion. It can be understood that the middle frame 3 in the present embodiment can be a component that accommodates the screen 2. For example, the middle frame 3 can be a middle frame, a back cover, a decorative cover or a bracket, etc., but the present disclosure does not specifically limit the type of the middle frame 3, that is, those skilled in the art can set or adjust it according to actual conditions, for example, Figure 1 or Figure 2 As shown, the middle frame 3 may be taken as an example, but the present disclosure is not limited thereto.

[0062] It can be understood that the wrapping part 4 can cover the gap between the screen 2 and the middle frame 3 and connect the screen 2 and the middle frame 3. The wrapping part 4 can be a covering part formed by injection molding or other methods. The wrapping part 4 protects the screen 2 and connects the middle frame 3 by covering the gap, and cooperates with the screen 2 and the middle frame 3 to provide better containment and protection effect.

[0063] It should be noted that the present disclosure does not specifically limit the type of the wrapping portion 4, that is, those skilled in the art can set or adjust it according to actual conditions. As long as the wrapping portion 4 can cover the gap between the screen 2 and the middle frame 3 and connect the screen 2 and the middle frame 3, it can be used.

[0064] It is understandable that if Figure 3 or Figure 4As shown, the wrapping portion 4 includes an adjacent first part 41 and a second part 42, which are arranged adjacent to each other in space and can be implemented with an integrated structure or a modular structure. It should be understood that no matter which structure is implemented, the first part 41 and the second part 42 are both components of the wrapping portion 4, and their positional relationship is adjacent.

[0065] For example, the first portion 41 may cover at least a portion of the display surface 23, where “at least a portion” refers to the coverage range of the first portion 41. In other words, when the first portion 41 covers the display surface 23, the coverage range is not necessarily the entire display surface 23, but at least covers a portion of the display surface 23.

[0066] In one possible scenario, Figure 3 or Figure 4 As shown, the first portion 41 may cover a small portion of the display surface 23 , which may be an edge portion of the display surface 23 . Covering the edge portion may provide some support to the wrapping portion 4 .

[0067] In another possible case, the first part 41 may also completely cover the display surface 23, that is, the first part 41 may cover the maximum area of ​​the display surface 23 in the non-bending part 22 of the screen 2, and covering the maximum area of ​​the display surface 23 can protect the display surface 23.

[0068] It is understandable that the present disclosure does not specifically limit the specific form of the first part 41 covering the display surface 23. The above situation is only an exemplary explanation of which parts of the display surface 23 the first part 41 can cover, but is not limited to the situation described in the above embodiment. As long as the first part 41 can be connected to the display surface 23, it can be used. In other words, as long as this condition is met, those skilled in the art can adjust the specific form of the first part 41 covering the display surface 23 according to actual conditions.

[0069] It can be understood that the second part 42 can cover the gap, which may refer to the space between the screen 2 and the middle frame 3. The second part 42 covering the gap means that the second part 42 is located in the space between the screen 2 and the middle frame 3, filling the gap between the two components. Structurally, the second part 42 is located in the gap to cover and fill it. Functionally, the second part 42 connects the screen 2 and the middle frame 3, and protects the screen 2 by covering the gap.

[0070] In one possible scenario, Figure 3 or Figure 4As shown, in the cross section of the electronic device 1, the gap has two dimensions of width (left-right direction) and depth (up-down direction), and the second part 42 can at least basically cover the width of the gap to protect the gap between the screen 2 and the middle frame 3.

[0071] In another possible case, the second portion 42 may substantially cover the width of the gap, and substantially cover the depth of the gap. In this case, a wider range of the gap may be covered, thereby increasing the strength of the wrapping portion 4 .

[0072] It is understood that the present disclosure does not specifically limit the specific form of the second part 42 covering the gap. The above situation is only an exemplary description of the degree of the second part 42 covering the gap, but is not limited to the situation described in the above embodiment. As long as the second part 42 can at least basically cover the width of the gap, it can be used. In other words, as long as it is under this condition, those skilled in the art can adjust the specific form of the second part 42 covering the gap according to actual conditions.

[0073] In the embodiment of the present disclosure, in the thickness direction D1 of the electronic device 1, the height of the wrapping portion 4 covering the display surface 23 may not exceed the height of the middle frame 3. Figures 3 to 6 As shown, the height of the wrapping portion 4 can be flush with the height of the middle frame 3. For example, the top surface of the first portion 41 and the second portion 42 is flush with the top of the middle frame 3. Compared with the solution of setting a screen pressing bar in the related art, this arrangement avoids increasing the thickness in the thickness direction, which is conducive to achieving a thin and light electronic device.

[0074] In some embodiments, in the thickness direction D1 of the electronic device 1 , the orthographic projection area of ​​the wrapping portion 4 may be located on the orthographic projection area of ​​the middle frame 3 .

[0075] In this embodiment, the orthographic projection area of ​​the wrapping portion 4 is located on the middle frame 3, which means that the outline of the wrapping portion 4 in the thickness direction D1 is within the outline of the middle frame 3 and will not exceed the boundary of the middle frame 3. Since the total thickness of the electronic device 1 is formed by the thickness of the middle frame 3 itself and the superposition of internal components, and the wrapping portion 4 is located inside the middle frame 3, if the outline of the wrapping portion 4 does not exceed the boundary of the middle frame 3, then the existence of the wrapping portion 4 will not increase the total thickness of the electronic device 1. The wrapping portion 4 will only occupy the internal space of the middle frame 3 without expanding the boundary of the middle frame 3, and therefore will not increase the total thickness of the electronic device 1. Compared with the related art, the present disclosure reduces the total thickness of the electronic device 1.

[0076] It can be understood that the thickness direction D1 refers to the side surface 24 of the electronic device 1 , and “in the thickness direction D1 ” refers to observing from the side surface 24 of the electronic device 1 .

[0077] It can be understood that the orthographic projection refers to the result of vertical projection. The orthographic projection area of ​​the wrapping portion 4 refers to the projection area of ​​the wrapping portion 4 vertically projected onto a plane in the thickness direction D1. The orthographic projection area of ​​the middle frame 3 refers to the projection area of ​​the middle frame 3 vertically projected onto a plane in the thickness direction D1.

[0078] It is understandable that when the electronic device 1 is placed in the thickness direction D1 for observation, and then the wrapping portion 4 is vertically projected onto a plane, the area of ​​the wrapping portion 4 obtained by projection should be located within the area where the vertical projection of the middle frame 3 is located. With this arrangement, the highest height of the wrapping portion 4 will not exceed the highest height of the middle frame 3, and compared with the related art, the stacking thickness of the electronic device 1 is reduced.

[0079] In some embodiments, Figure 3 or Figure 4 As shown, the middle frame 3 may include a middle plate 32 and side edges 33 connected to each other, and the display surface 23 , the side surface 24 and the back surface 25 may be adjacent in sequence, wherein the side surface 24 may be opposite to the side edge 33 , and the back surface 25 may be opposite to the middle plate 32 .

[0080] Among them, Figure 3 or Figure 4 As shown, the middle plate 32 can be the middle structure of the middle frame 3, which plays the role of bearing and supporting the screen 2. The side edges 33 can be the surrounding edge structures. The side edges 33 can be connected with the middle plate 32 to form a middle frame 3 with mechanical strength. The side edges 33 can block the border area for protection and decoration. The cooperation between the middle plate 32 and the side edges 33 can better install and protect the screen 2.

[0081] It is understandable that the middle plate 32 and the side 33 of the middle frame 3 can be in a mutually connected relationship, wherein the two can be either integrated or assembled after being separated. For example, the middle plate 32 and the side 33 can be realized by integrated molding, mechanical connection, adhesive connection, thermal melting connection, lock connection, etc., but the present disclosure does not specifically limit the type of connection between the middle frame and the side 33, that is, those skilled in the art can set or adjust according to actual conditions, as long as the middle plate 32 and the side 33 can become components of the middle frame 3 and jointly define the frame structure of the middle frame 3.

[0082] like Figure 3 or Figure 4As shown, the non-bending portion 22 may include a side surface 24 and a back surface 25 in addition to the display surface 23, wherein the side surface 24 may be the side area of ​​the screen 2, and the back surface 25 may refer to the bottom area of ​​the screen 2. The display surface 23, the side surface 24 and the back surface 25 are arranged and connected in sequence in spatial position to form the outer surface structure of the screen 2 in three directions, wherein the display surface 23 is used to display images, and the side surface 24 and the back surface 25 play a protective and non-display decorative role, and the three surfaces can together constitute the three-dimensional shape of the screen 2.

[0083] like Figure 3 or Figure 4 As shown, the side 24 can be opposite to the side 33, and the bottom plate can be opposite to the middle plate 32. For example, when the screen 2 is installed inside the middle frame 3, the side 24 of the screen 2 and the side 33 of the middle frame 3 are in a face-to-face corresponding relationship, and the two form a face-to-face geometric relationship. At the same time, the back 25 of the screen 2 and the middle plate 32 of the middle frame 3 are also face-to-face corresponding, and the two form a face-to-face relative geometric relationship. Through this face-to-face relative structural arrangement, the side 24 of the screen 2 is aligned with the side 33, and the back 25 is aligned with the middle plate 32, so that the screen 2 can be firmly installed in the middle frame 3, and the face-to-face correspondence between the side 24 and the side 33, and the back 25 and the middle plate 32 can enhance the positioning stability of the screen 2.

[0084] In some embodiments, before the screen 2 is installed inside the middle frame 3, the wrapping part 4 is connected to the screen 2 through an integrated injection molding process, and after the injection-molded material of the wrapping part 4 is cured to form a solid state, the screen 2 is set in the middle frame 3.

[0085] For example, the integral injection molding process of the wrapping part 4 may be: placing a pre-prepared screen 2 into an injection mold, injecting liquid wrapping part 4 material such as UV curing glue into the mold to cover the connection part of the screen 2, and taking out the wrapping part 4 material after it solidifies into a solid in the mold, thereby obtaining the wrapping part 4 connected to the screen 2, and then installing the formed screen 2 and wrapping part 4 assembly in the middle frame 3, and after subsequent connection and sealing operations, the electronic device 1 is finally assembled.

[0086] In some embodiments, Figure 3 or Figure 4 As shown, the electronic device 1 may further include a first adhesive layer 5 , and a side of the second portion 42 close to the side edge 33 may be connected via the first adhesive layer 5 .

[0087] In this embodiment, the connection between the second part 42 and the side 33 is achieved by providing a first adhesive layer 5. The first adhesive layer 5 can serve as a bonding interface. While achieving the connection between the two, it can also form a sealing effect between the screen 2 and the middle frame 3.

[0088] Among them, Figure 3 or Figure 4 As shown, the first adhesive layer 5 is an adhesive material layer that can play a role of bonding and connecting. For example, the first adhesive layer 5 can be formed by solidifying a liquid adhesive, or can be a double-sided adhesive material with bonding properties, but the present disclosure does not specifically limit the type of the first adhesive layer 5, that is, those skilled in the art can set or adjust it according to actual conditions, as long as the first adhesive layer 5 can play a role of bonding and connecting.

[0089] In this embodiment, the side of the second portion 42 close to the side edge 33 refers to the surface facing the side edge 33 when the second portion 42 is in a state opposite to the side edge 33. The first adhesive layer 5 can cover this surface to implement the bonding connection between the second portion 42 and the side edge 33.

[0090] Figure 5 According to another exemplary embodiment Figure 2 Schematic diagram of the structure of part B cut along line A-A'. Figure 6 According to another exemplary embodiment Figure 2 Schematic diagram of the structure of part C cut along line A-A'.

[0091] In some embodiments, Figure 5 or Figure 6 As shown, the wrapping portion 4 may further include a third portion 43 , the third portion 43 may be adjacent to the second portion 42 , and the third portion 43 may cover the side surface 24 .

[0092] In this embodiment, the side 24 is covered by providing a third portion 43 adjacent to the second portion 42. On the one hand, the contact area between the wrapping portion 4 and the screen 2 can be increased to increase the connection strength between the wrapping portion 4 and the screen 2. On the other hand, the third portion 43 achieves sealing or protection of the side 24 of the screen 2. On the other hand, the third portion 43 can also increase the contact area between the wrapping portion 4 and the side edge 33 to increase the connection strength between the wrapping portion 4 and the side edge 33.

[0093] It can be understood that the third part 43 is adjacent to the second part 42, which may mean that the third part 43 is disposed adjacent to the second part 42 in space. The third part 43, the second part 42 and the first part 41 may be integrally formed to form the wrapping part 4.

[0094] In some embodiments, Figure 5 or Figure 6As shown, the electronic device 1 may further include a second adhesive layer 6, and a side of the third portion 43 close to the side edge 33 may be connected via the second adhesive layer 6. By providing the second adhesive layer 6, the connection between the third portion 43 and the side edge 33 is achieved, and the second adhesive layer 6 may serve as a bonding interface, and while achieving the connection between the two, a sealing effect may also be formed between the screen 2 and the middle frame 3.

[0095] It should be noted that the second adhesive layer 6 may refer to the description of the first adhesive layer 5 in the aforementioned embodiment, and the type of the second adhesive layer 6 may be similar to or the same as that of the first adhesive layer 5 , which will not be described in detail in the present disclosure.

[0096] In some embodiments, the first adhesive layer 5 may be formed by solidifying a liquid adhesive, and / or the second adhesive layer 6 may be formed by solidifying a liquid adhesive.

[0097] The liquid glue may be a flowable liquid adhesive, which may be injected between the wrapping portion 4 and the middle frame 3 and then cured to form a first adhesive layer 5 and / or a second adhesive layer 6 to achieve a bonding connection between the wrapping portion 4 and the middle frame 3. For example, the liquid glue may be an ultraviolet curing glue, a thermosetting glue, an epoxy glue, etc., but the present disclosure does not specifically limit the type of the liquid glue, that is, those skilled in the art may set or adjust according to actual conditions, as long as the liquid glue is a flowable liquid adhesive.

[0098] The term "and / or" means that there are three situations. In the first situation, the first adhesive layer 5 can be solidified by liquid glue, and the second adhesive layer 6 can be solidified by non-liquid glue; in the second situation, the first adhesive layer 5 can be solidified by non-liquid glue, and the second adhesive layer 6 can be solidified by liquid glue; in the third situation, the first adhesive layer 5 can be solidified by liquid glue, and the second adhesive layer 6 can also be solidified by liquid glue.

[0103] In some embodiments, Figure 7 or Figure 8 As shown, the screen 2 may further include a screen back fixing portion 7, which may be disposed on the back 25 of the screen 2, and the screen back fixing portion 7 may fix the screen 2 and the middle frame 3. For example, the screen back fixing portion 7 may fix the screen 2 and the middle frame 3 by fixing the wrapping portion 4 to the middle frame 3.

[0104] In some embodiments, the screen back fixing part 7 is adhesively fixed to the back side 25 of the screen 2. For example, the screen back fixing part 7 may include any one or more of UV light curing glue, hot melt glue, transparent epoxy glue, optical grade silicone, and optical grade polycarbonate.

[0105] like Figure 7 or Figure 8 As shown, the wrapping portion 4 extends from the display surface 23 of the screen 2 to the back surface 25 of the screen 2, and the screen back fixing portion 7 connects the wrapping portion 4 covering the back surface 25 of the screen 2 to the middle frame 3. For example, in the present disclosure, a side of the fourth portion 44 close to the middle plate 32 can be connected through the screen back fixing portion 7. With this arrangement, the screen 2 can be connected to the middle plate 32 of the middle frame 3 through the screen back fixing portion 7, and at the same time, the screen back fixing portion 7 can form a sealing effect between the screen 2 and the middle frame 3 while realizing the connection between the two.

[0106] In the present disclosure, the screen back fixing portion 7 may also be a part of the wrapping portion 4. The present disclosure does not make any specific limitation, as long as the screen back fixing portion 7 can fix the screen 2 and the middle frame 3.

[0107] In this disclosure, Figure 5 As shown, the outer surface of the side 24 of the screen 2 is opposite to the middle frame 3, and the second portion 42 can wrap and cover the outer surface of the side of the screen 2. For example, in some embodiments, taking a mobile phone as an example of an electronic device, Figure 5The side of the screen 2 shown in the figure can be the upper side, left side or right side of the mobile phone.

[0108] In this disclosure, Figure 6 As shown, the screen 2 may include a wiring portion 26 and a protective layer 27. The wiring portion 26 may include a portion extending from the side surface 24 of the screen 2 and bent toward the back surface 25 of the screen 2 and fixed to the back surface 25.

[0109] In the present disclosure, the wiring portion 26 may have a first side facing the middle frame 3, and the protective layer 27 may be arranged on the first side. The first side may also be considered as the outer side of the wiring portion 26. In the present disclosure, the wrapping portion 4 may cover the protective layer 27. In the present disclosure, the protective layer 27 may be a buffer layer and may have a certain flexibility. For example, the protective layer 27 may be an adhesive layer, for example, a UV adhesive layer. The wrapping portion 4 covers the protective layer 27. On the one hand, it may further include the wiring portion 26 to avoid damage to the circuits, components, etc. on the wiring portion 26. On the other hand, by covering the wrapping portion 4, the under-screen bonding of the folding screen may be limited. For example, if the wrapping portion 4 does not cover the protective layer 27, after the under-screen bonding of the folding screen, the wiring portion 26 and the protective layer 27 may be damaged during the disassembly process. The setting of the present disclosure can avoid damage to the wiring portion 26 and the protective layer 27 during the disassembly process, and thus, the present disclosure can achieve under-screen bonding of the folding screen.

[0110] In this disclosure, Figure 6 As shown, the wrapping portion 4 can fill the gap between the wiring portion 26 and the side 24. For example, the second portion 42 can fill the space between the wiring portion 26 and the screen 2.

[0111] In some embodiments, taking a mobile phone as an example of an electronic device, Figure 6 The side of the screen 2 shown in the figure may be the bottom side of the mobile phone. The bottom side of the mobile phone may be the wiring side of the screen 2, through which the circuit of the display element of the screen 2 is connected to the mainboard. For example, a COP, COF or COG packaging process may be used on this side.

[0112] In some embodiments, the screen back fixing part 7 can be any one of double-sided adhesive, foam, and structural adhesive. With this arrangement, a reliable connection between the fourth part 44 and the middle plate 32 is achieved, wherein the double-sided adhesive has good bonding performance, and the foam and structural adhesive have both buffering and supporting functions. Using any of these materials as the base material of the screen back fixing part 7 can enhance the connection strength between the fourth part 44 and the middle plate 32 to prevent falling off, and at the same time has a certain buffering and supporting effect, thereby improving the reliability and anti-seismic performance of the electronic device 1.

[0113] It should be noted that the present disclosure does not specifically limit the type of substrate selected for the screen back fixing part 7 , that is, those skilled in the art can set or adjust it according to actual conditions, as long as the screen back fixing part 7 can achieve the connection between the fourth part 44 and the middle plate 32 .
