Screen disassembly and reuse can greatly reduce the associated scrapping costs caused by disassembly due to various defects in the production of the whole machine. Therefore, various terminal companies have a strong demand for screen disassembly and reuse. Utility Model Content

[0008] In the embodiment of the present application, a connector is added between the screen and the middle frame to achieve a fixed connection between the screen and the middle frame through the connector, thereby decoupling the direct force relationship between the screen and the middle frame. This can avoid direct bonding between the screen and the middle frame through the adhesive backing, and therefore there is no need to directly peel off the screen and the adhesive backing, thereby reducing direct deformation and force on the screen, and improving the success rate of disassembling the screen.

[0067] Figure 1 It is a schematic diagram of the overall structure of an electronic device 100 provided in an embodiment of the present application.

[0068] In the embodiment of the present application, the electronic device 100 is an electronic device with a communication function. The communication technology used by the electronic device 100 includes, but is not limited to, Bluetooth (BT) communication technology, global positioning system (GPS) communication technology, wireless fidelity (Wi-Fi) communication technology, global system for mobile communications (GSM) communication technology, wideband code division multiple access (WCDMA) communication technology, long term evolution (LTE) communication technology, fifth generation (5G) communication technology, SUB-6G communication technology (also known as low to medium frequency spectrum communication technology or centimeter wave communication technology, where SUB-6G refers to the frequency band less than 6 GHz in 5G), millimeter wave (mmW) communication technology, sixth generation (6G) communication technology and other future communication technologies.

[0069] The electronic device 100 in the embodiment of the present application can be a mobile phone (such as a folding screen mobile phone), a personal digital assistant (PDA) computer, a tablet computer, a laptop computer, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a smart watch, a smart wristband, a car computer, a TV (or a smart screen), an augmented reality (AR) / virtual reality (VR) device, a wearable device, a wireless headset, and other electronic devices with a display screen, and can also be other handheld devices with wireless communication functions, computing devices, or processing devices connected to a wireless modem, vehicle-mounted devices, and other electronic devices with a display screen. The embodiment of the present application does not impose any special restrictions on the specific form of the electronic device 100. For the convenience of explanation and understanding, the following description is based on the example of the electronic device 100 being a folding screen mobile phone.

[0070] like Figure 1 As shown, the electronic device 100 may include a screen 110 and a middle frame 120. The middle frame 120 is a support frame located inside the electronic device 100, and mainly plays a supporting role for the entire device. For example, the middle frame 120 can be used to support and fix the screen 110. Exemplarily, the middle frame 120 can be formed of a metal material such as copper, magnesium alloy, stainless steel, etc.

[0071] Exemplarily, the electronic device 100 may also include a cover, a back cover, an antenna, a speaker, a camera, a microphone, a sensor, a memory, a processor, a battery and other electronic components, which are not limited in the present application.

[0072] The screen 110 can be used to display images. Exemplarily, the screen 110 may include a liquid crystal display panel (LCD), a light emitting diode (LED) display panel, an organic light-emitting diode (OLED) display panel, an active-matrix organic light emitting diode or an active-matrix organic light emitting diode (AMOLED) display panel, a flexible light emitting diode (FLED) display panel, a quantum dot light emitting diode (QLED) display panel, etc., and the embodiments of the present application are not limited to this.

[0073] Figure 2 A schematic diagram of a screen fixing bonding area of ​​an electronic device is shown. Figure 3 A cross-sectional schematic diagram is shown after the screen and the middle frame are bonded and fixed. Figure 4 A schematic diagram of screen deformation during screen removal is shown.

[0074] like Figure 2 As shown, the electronic device 100 can be divided into a middle frame area 101, a hinge area 102 and an adhesive area 103, and the adhesive area 103 can be located at the edge of the middle frame area 101 and the hinge area 102. For example, when the electronic device 100 is a folding screen mobile phone, the adhesive area 103 can be located at the edge area of ​​the screen 110 and the hinge area of ​​the folding screen.

[0075] It should be understood that the screen 110 of the electronic device 100 and the middle frame 120, the shaft and other structural parts can be fixed by double-sided tape and / or glue. Figure 3 As shown, the screen 110 and the middle frame 120 may be fixedly connected via an adhesive layer 130 .

[0076] like Figure 4 As shown, when the screen 110 is disassembled, it is necessary to remove it from the first direction (i.e. Figure 4 The first direction is the thickness direction of the electronic device. After the flexible screen is deformed by stress, the packaging fails, and the screen displays abnormalities as black spots or local rainbow patterns. In addition, when the screen 110 is disassembled, a heating table is required to reduce the adhesion of the adhesive layer 130, which places high demands on the disassembly environment and jigs. In addition, the scenario of heating and disassembly may involve the disassembly of the battery of the electronic device 100. For the battery bonded by the adhesive layer 130, it will further lead to the joint scrapping of the battery.

[0077] It should be noted that the biggest problem with the current technical solution is that the success rate of screen removal is low, and the screen will inevitably deform during the screen removal process. The local stress concentration or excessive deformation of the screen 110 (such as a flexible screen) will cause the inorganic layer of the light-emitting devices such as the thin film transistor (TFT) and electroluminescence (EL) of the screen 110 to crack, further causing the EL material to fail due to water and oxygen corrosion, forming black spots. Therefore, it is necessary to provide an electronic device to solve the above problems.

[0078] The following will be combined Figures 5 to 11 The electronic device provided by the embodiment of the present application is described in detail. Figure 5 It is a cross-sectional schematic diagram of an electronic device provided in an embodiment of the present application. Figure 6 It is a cross-sectional schematic diagram of another electronic device provided in an embodiment of the present application. Figure 7 It is a cross-sectional schematic diagram of another electronic device provided in an embodiment of the present application. Figure 8 It is a cross-sectional schematic diagram of a middle frame provided in the present application. Fig. 9 It is a side view schematic diagram of a connecting piece provided in an embodiment of the present application. Fig.10 It is a top view schematic diagram of a connector provided in an embodiment of the present application. Fig.11 It is a schematic diagram of the slotted and holed area of ​​the middle frame.

[0079] like Figures 5 to 7 As shown, the electronic device 100 provided in the embodiment of the present application may include a screen 110, a middle frame 120 and a connector 300, and the screen 110 and the middle frame 120 may be fixedly connected by the connector 300. The middle frame 120 and the connector 300 may constitute a middle frame structure.

[0080] It should be noted that in the present application, the screen 110 and the middle frame 120 are not directly fixedly connected by the adhesive layer 130, but are fixedly connected by a connecting member 300, thereby avoiding deformation of the screen 110 caused by directly peeling off the adhesive layer 130 when disassembling the screen 110.

[0081] In some examples, the electronic device 100 may further include an adhesive layer 130, and the top surface of the connector 300 and the screen 110 may be fixedly connected by the adhesive layer 130. The projection of the adhesive layer 130 on the screen 110 along the first direction is located within the projection range of the connector 300 on the screen 110 along the first direction, and the first direction is the thickness direction of the screen 110. It should be understood that by limiting the projection of the adhesive layer 130 on the screen 110 along the first direction to be located within the projection range of the connector 300 on the screen 110 along the first direction, direct contact between the adhesive layer 130 and the middle frame 120 can be avoided, thereby avoiding the screen 110 and the middle frame 120 from being bonded together.

[0082] Exemplarily, the thickness of the adhesive layer 130 is about 50 μm.

[0083] Exemplarily, the adhesive layer 130 may be double-sided adhesive and / or liquid adhesive. For example, the screen 110 may be fixed to the middle frame 120 by overall laying of double-sided adhesive and local dispensing of adhesive.

[0084] like Figure 8 As shown, the middle frame 120 has a receiving groove, which can be wide at the top and narrow at the bottom. It should be understood that the receiving groove can also be called a receiving through hole, and this application does not limit this. Exemplarily, the middle frame 120 has a receiving groove, and the connector 300 can be embedded in the receiving groove and fixedly connected to the middle frame 120; the top surface of the connector 300 (i.e., the side of the connector 300 close to the screen 110) can be fixedly connected to the screen 110. For example, the connector 300 can be fixedly connected to the screen 110 through the adhesive layer 130, or it can be fixedly connected to the screen 110 through other mechanical locking methods.

[0085] In some examples, such as Figure 5 As shown, the side of the connector 300 close to the screen 110 is flush with the side of the middle frame 120 close to the screen 110, so that the connector 300 can be embedded in the middle frame 120. In this case, the side of the connector 300 close to the screen 110 is flush or approximately flush with the side of the middle frame 120 close to the screen 110. Since the thickness of the adhesive layer 130 is relatively small, the surface flatness of the screen of the electronic device 100 can be guaranteed to a certain extent, making the screen appearance more refined, and avoiding the occurrence of screen pits to a certain extent, so that the reliability of the screen is higher.

[0086] In other examples, such as Figure 6As shown, at least part of the adhesive layer 130 can be located in the receiving groove of the middle frame 120. Exemplarily, a portion of the adhesive layer 130 can be located in the receiving groove of the middle frame 120; the other portion protrudes toward the screen 110 and is located outside the receiving groove of the middle frame 120. It should be understood that at least part of the adhesive layer can be located in the receiving groove, so that the thickness of the electronic device can be reduced to a certain extent. In addition, the bonding processing requirements of the connector 300 of the electronic device and the screen 110 are also simplified.

[0087] In some other examples, such as Figure 7 As shown, the adhesive layer 130 may also be completely located in the receiving groove of the middle frame 120, and the side of the adhesive layer 130 close to the screen 110 is flush with the side of the middle frame 120 close to the screen 110. In this case, the connector 300 and the adhesive layer 130 may both be located in the receiving groove, and the side of the adhesive layer 130 close to the screen 110 is flush or approximately flush with the side of the middle frame 120 close to the screen 110, so that the screen surface of the electronic device 100 is relatively flat, the flatness of the screen is ensured, the screen appearance is more refined, screen pits are avoided, and the reliability of the screen is higher.

[0088] In some examples, such as Figure 8 As shown, the accommodating groove on the middle frame 120 may include a first groove 121 and a first through hole 122, that is, the middle frame 120 has a first groove 121 and a first through hole 122, and the projection of the first through hole 122 on the screen 110 along the first direction is located within the projection range of the first groove 121 on the screen 110 along the first direction, and the first direction is the thickness direction of the screen 110.

[0089] It should be understood that there may be multiple first through holes 122 , and the projection of each of the multiple first through holes along the first direction on the screen 110 is located within the projection range of the first groove 121 along the first direction on the screen 110 .

[0090] like Fig. 9 and Fig.10 As shown, the connector 300 may include a main body 320 and a connecting portion 310, wherein the connecting portion 310 extends outwardly from the main body 320 to form a protrusion, and the connecting portion 310 has an internal thread or an external thread structure, which can be used for screws or other fasteners to fix the connection. Among them, the connecting portion 310 may be a nut seat.

[0091] Exemplarily, the main body 320 may include a plurality of connection portions 310 , and the plurality of connection portions 310 all extend outward in a second direction, and the second direction may be a thickness direction of the connection member 300 .

[0092] Exemplarily, the projection of the connecting portion 310 on the main body 320 along the second direction may be annular, the connecting portion 310 may be a hollow structure, and the inner wall of the connecting portion 310 may be provided with an internal thread or an external thread structure for fixed connection with a fastener (such as a screw).

[0093] It should be understood that the embodiment of the present application does not limit the shape and number of the connecting member 300, and the connecting member 300 or the main body 320 can be in the shape of an elongated strip.

[0094] It should be understood that the connector 300 can be placed in the receiving groove on the middle frame 120 and fixedly connected to the middle frame 120; the top surface of the connector 300 (i.e., the top surface of the main body 320 or the side of the main body 320 away from the connecting portion 310) can be fixedly connected to the screen 110. In other words, the connector 300 can be connected between the screen 110 and the middle frame 120, and the fixed connection between the screen 110 and the middle frame 120 is achieved through the connector 300, and the direct force relationship between the screen 110 and the middle frame 120 is decoupled, so that the screen 110 and the middle frame 120 can be avoided from being directly bonded by adhesive or glue.

[0095] It should be understood that a first through hole 122 may be provided at a position on the middle frame 120 corresponding to the connection portion 310 (such as a nut seat), so that the connection portion 310 (such as a nut seat) may pass through the middle frame 120 and be fixedly connected to the fastener 400 (such as a screw).

[0096] like Figures 5 to 7 As shown, the main body 320 of the connector 300 can be located in the first groove 121, and the connecting portion 310 (such as a nut seat) can be located in the first through hole 122; the electronic device 100 can also include a fastener 400 (such as a screw), and the fastener 400 (such as a screw) can pass through the first through hole 122 and be fixedly connected to the connecting portion 310 (such as a nut seat) to fix the connector 300 on the middle frame 120.

[0097] It should be understood that the connector 300 may be provided with a connecting portion 310 (such as a nut seat), and the connector 300 may be locked on the middle frame 120 by using the connecting portion 310 (such as a nut seat) in combination with the fastener 400 (such as a screw), thereby ensuring the connection stability between the connector 300 and the middle frame 120. In addition, when disassembling the screen 110, there is no need to use tools such as a heating platform, but the fastener 400 (such as a screw) may be directly removed from the middle frame 120, which is simple to operate, and the screen is not easily deformed after disassembly, which is more conducive to the reuse assembly of the screen.

[0098] In some examples, combined Figures 5 to 8It can be known that the first through hole 122 may include a first part and a second part, the first part is used to accommodate the connection part 310 (such as a nut seat), and the second part is used to accommodate a part of the fastener 400 (such as a screw cap of a screw). In other words, the nut seat and the screw can be locked in the first through hole 122, the screw will not be exposed, will not protrude on the surface of the middle frame 120, and the screw is locked on the nut seat to achieve a fixed connection between the connector 300 and the middle frame 120.

[0099] It should be understood that the present application mainly describes the connection portion 310 of the connector 300 as a nut seat and the fastener 400 as a screw. In the embodiment of the present application, the connector 300 can also be fixedly connected to the middle frame 120 in other ways, for example, the connector 300 is fixedly connected to the middle frame 120 by snap fastening or other mechanical locking methods.

[0100] In some examples, such as Fig.11 As shown, the first groove 121 on the middle frame 120 is provided in the hinge area 102 of the electronic device 100 and / or the edge area of ​​the middle frame 120. A first through hole 122 is provided at a local position of the first groove 121. In other words, the hinge area 102 of the electronic device 100 and / or the edge area of ​​the middle frame 120 may be provided with a receiving groove for accommodating the connector 300, wherein the edge position of the middle frame 120 may be, for example, a position at a preset distance (e.g., 0.3 mm) from the side of the middle frame 120.

[0101] It should be understood that in order to ensure the connection stability between the screen 110 and the middle frame 120 of the electronic device, a plurality of first grooves 121 can be set in the hinge area 102 of the electronic device 100 and / or the edge area of ​​the middle frame 120, and one or more first through holes 122 can be opened in the first groove 121. The connecting part 310 (such as a nut seat) and the fastener 400 (such as a screw) can be locked in the first through hole 122 to achieve a fixed connection between the connecting part 300 and the middle frame 120, thereby achieving a fixed connection between the screen 110 and the middle frame 120.

[0102] It should be noted that when the electronic device 100 adopts the connector solution provided in the embodiment of the present application, by adding a connector 300 between the screen 110 and the middle frame 120, the fixed connection between the screen 110 and the middle frame 120 is realized through the connector 300, and the direct force relationship between the screen 110 and the middle frame 120 is decoupled, so that the direct bonding between the screen 110 and the middle frame 120 through the back glue (such as the adhesive layer 130) can be avoided. Therefore, there is no need to directly peel the screen and the back glue, which reduces the direct deformation and force of the screen, improves the success rate of disassembling the screen, and does not affect the disassembly and reuse of the screen. In other words, in the process of screen assembly, screen disassembly and secondary assembly of the screen, large deformation of the screen 110 can be avoided, thereby avoiding screen failure caused by screen disassembly.

[0103] The following combination Figure 12 to Figure 14 A schematic diagram illustrating the process of screen assembly, screen disassembly, and screen secondary assembly of an electronic device provided by an embodiment of the present application.

[0104] like Fig.12 As shown, during the screen assembly process of the electronic device 100, the connector 300 can first be placed in the receiving groove on the middle frame 120, and the fastener 400 can be inserted into the first through hole 122 from the side of the middle frame 120 away from the screen 110 to fix the connector 300 on the middle frame 120. Then, double-sided tape and / or glue can be pasted on the side of the connector 300 close to the screen 110 to form an adhesive layer 130. It should be noted that the projection of the adhesive layer 130 on the screen 110 along the first direction is located within the projection range of the connector 300 on the screen 110 along the first direction. Finally, the screen 110 can be pasted on the side of the adhesive layer 130 away from the middle frame 120 to achieve a fixed connection between the connector 300 and the screen 110, so that the screen 110 can be assembled on the middle frame 120.

[0105] like Fig.13 As shown, during the screen disassembly process of the electronic device 100, the fully assembled electronic device can be obtained first, and then the fastener 400 (such as a screw) can be removed from the middle frame 120 using a screwdriver or other tool, and finally the screen 110 can be separated from the middle frame 120 together with the connector 300. The screen 110 and the middle frame 120 are connected by the connector 300, and there is no need to directly bond the screen 110 to the middle frame 120 through the adhesive. During the screen disassembly process, the screen 110 does not need to be peeled off from the adhesive, thereby avoiding stress and deformation of the screen. In addition, during the screen disassembly process, only the screws fixing the middle piece need to be removed with a screwdriver, and heating is not required. Therefore, there is no need for the intervention of a non-heating platform, and the disassembly is simpler, and there is no problem of disassembly and scrapping of the battery.

[0106] like Fig.14 As shown, during the secondary assembly of the screen of the electronic device 100, the screen 110 together with the connector 300 can first be aligned with the middle frame 120, that is, the connecting portion 310 (such as) of the connector 300 is aligned with the first through hole 122 on the middle frame 120, so that the projections of the two in the first direction overlap. Then, the screen 110 together with the connector 300 are placed in a predetermined position of the middle frame 120 for pre-fixation. Finally, the connector 300 is locked on the middle frame 120 by a fastener 400 (such as a screw), and the connector 300 is fixed to the middle frame 120, so that the screen 110 and the middle frame 120 can be fixed.

[0107] In summary, in order to decouple the fixed relationship between the screen 110 and the whole device, the adhesive layer 130 can be first fixed to the connector 300, then the connector 300 can be fixed to the middle frame 120, and finally the screen 110 can be bonded to the adhesive layer 130. In this way, when removing the screen 110, there is no need to directly peel the screen 110 from the adhesive (adhesive layer 130), which reduces the direct deformation and force of the screen 110 and improves the success rate of removing the screen.

[0108] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
