[0028] In related technologies, the storage convenience and user experience of electronic devices are closely linked to their thinness and lightness. However, the overall thickness of an electronic device is limited by the structure and material of the midframe. When the midframe adopts an integrated structure, the material of the midframe is the same in areas with different strength requirements, thus affecting the structural layout flexibility of the midframe, the overall thickness, and the overall performance of the electronic device.

[0029] The present disclosure provides an electronic device, Figure 1 is a schematic diagram of a partial cross-sectional structure of an electronic device in an exemplary embodiment of the present disclosure, such as Figure 1 As shown, the electronic device 1 includes a middle frame structure 11, a battery module 12, and a screen module 13. The middle frame structure 11 includes a middle plate 112 and a frame 111 assembled on the periphery of the middle plate 112. The battery module 12 and the screen module 13 are arranged on both sides of the middle plate 112. The middle plate 112 includes a bent portion 1121. The bent portion 1121 forms a wiring groove 1122 on the side of the middle plate 112 facing the battery module 12. The bent portion 1121 forms a protrusion on the side of the middle plate 112 facing the screen module 13. A grounding layer 1123 is provided on the side of the middle plate 112 facing the screen module 13. The grounding layer 1123 is located outside the bent portion 1121.

[0030] Since the middle plate 112 of the above-mentioned middle frame structural member 11 includes a bent portion 1121, the bent portion 1121 forms a wiring groove 1122 on the side of the middle plate 112 facing the battery module 12, and the bent portion 1121 forms a protrusion on the side of the middle plate 112 facing the screen module 13. After the electronic device 1 is assembled, the gap between the protrusion of the middle plate 112 and the screen module 13 is small or non-existent. In response to the protrusion formed toward the screen module 13, a grounding layer 1123 is provided on the side of the middle plate 112 facing the screen module 13 outside the bent portion 1121, thereby preventing the bent portion 1121 from being connected to the screen module 13 due to their proximity, thereby reducing performance interference with the screen module 13. Among them, the grounding layer 1123 can be used to achieve grounding of the antenna module and other RF-related functions.

[0031] It should be noted that the above-mentioned grounding layer 1123 can be a coating, and the above-mentioned coating can be formed on the middle plate 112 by PVD (Physical Vapor Deposition). In other embodiments, the grounding layer 1123 can be a coating, a film layer, etc. The material of the grounding layer 1123 can be nickel, copper, steel, aluminum or an alloy, etc., whichever is greater, and the present disclosure is not limited to this. When the grounding layer 1123 adopts PVD coating, the area where the bent portion 1121 faces the screen module 13 can be shielded to obtain a PVD coating in the area other than the bent portion 1121.

[0032] The electronic device 1 may further include a fingerprint module, and the wiring groove 1122 may be used to accommodate the connection wiring 14 of the fingerprint module. Alternatively, the wiring groove 1122 may also be used to accommodate wiring of other functional modules, which is not limited in this disclosure.

[0033] The grounding layer 1123 can cover the area of the side of the middle plate 112 facing the screen module 13, excluding the bent portion 1121. Alternatively, the grounding layer 1123 can be located in a specific area of the side of the middle plate 112 facing the screen module 13 to achieve a grounding effect. For example, the middle plate 112 includes a main portion 1125 located outside the bent portion 1121. The main portion 1125 and the bent portion 1121 form the entire middle plate 112. The grounding layer 1123 covers the side of the main portion 1125 facing the screen module 13.

[0034] In some embodiments, the side of the bent portion 1121 facing the screen module 13 can be covered with an insulating layer 1124 to obtain an insulating effect on the side of the bent portion 1121 facing the screen module 13, further preventing the screen module 13 from being connected to the middle plate 112, and helping to improve the reliability of the setting of the middle plate 112 and the compactness of the overall structure of the electronic device 1.

[0035] The insulating layer 1124 may be made of ink, or other insulating materials such as plastic, rubber, etc., which are not limited in this disclosure. When the insulating layer 1124 is made of ink, the ink layer may be formed using a silk screen process.

[0036] In some embodiments, electronic device 1 may further include a filling layer 15. Midplane 112 includes a main body 1125 located outside of bend 1121. A gap is defined between main body 1125 and screen module 13, and filling layer 15 is disposed in this gap. Filling layer 15 supports the gap between main body 1125 and screen module 13, thereby improving the reliability and stability of the fit between midplane 112 and screen module 13.

[0037] The filling layer 15 may be a graphite layer 152 and / or a Mylar layer 151. The filling layer 15 may achieve a supporting effect by completely filling the gap between the main body 1125 and the screen module 13, or may be disposed in a portion of the gap to achieve the desired supporting effect by abutting against the main body 1125 and the screen module 13, respectively. For example, when the filling layer 15 is a graphite layer 152, it may be filled in the gap formed between the main body 1125 and the screen module 13. When the filling layer 15 is a Mylar layer 151, the Mylar layer 151 may bend and coil within the gap and abut against the main body 1125 and the screen module 13, respectively, to achieve the desired supporting effect.

[0038] In the above embodiment, the material of the middle plate 112 is carbon fiber. The middle frame structural member 11 is disassembled to obtain the middle plate 112 and the frame 111. The middle plate 112 can be used to form a battery compartment. The middle plate 112 made of carbon fiber is thin and can reduce the thickness of the conventional metal integrated middle frame by more than 50%. The density of the carbon fiber middle plate 112 is lower than that of metal, which reduces the weight of the middle frame structural member 11 by more than 50%, thereby improving the competitiveness of the electronic device 1 in terms of thickness and weight. In other embodiments, the middle plate 112 can also be made of other lightweight materials with support strength that meets the requirements, and this disclosure is not limited to this.

[0039] The frame 111 can be made of metal to enhance the overall structural strength and functional requirements of the frame 111. Alternatively, the frame 111 can be made of a non-metallic material, depending on whether it can achieve the desired strength and functionality. The middle plate 112 and the frame 111 can be assembled and fixed by metallurgical bonding, clamping, adhesive bonding, etc.

[0040] Figure 2 is a structural diagram of an electronic device in an exemplary embodiment of the present disclosure, Figure 1 Can be Figure 2 The electronic device 1 is shown as a partially enlarged view at position AA. Figure 3 FIG. 1 is a partial enlarged schematic diagram of an electronic device 1 at position BB in an exemplary embodiment of the present disclosure. Figure 2 、 Figure 3 As shown, in some embodiments, the electronic device 1 further includes a rotating connection mechanism 16, and the middle frame structure 11 includes a pair of middle plates 112 located on either side of the rotating connection mechanism 16. Each middle plate 112 is provided with a battery and a screen module 13 on either side of the thickness direction. This structural arrangement, when applied to a foldable electronic device 1, helps to improve the overall lightness and thinness of the foldable electronic device 1.

[0041] In some embodiments, the middle plate 112 includes a main portion 1125 located outside the bent portion 1121. A first gap is defined between a first subsection 1125a of the main portion 1125 near the rotational connection mechanism 16 and the screen module 13. This first gap is filled with a Mylar layer 151. The Mylar layer 151 provides support near the rotational connection mechanism 16, helping to accommodate stress generated during the bending process of the electronic device 1 and improving the reliability of the electronic device 1.

[0042] like Figure 3 、 Figure 4As shown, the main body 1125 also includes a second subsection 1125b adjacent to the first subsection 1125a. A second gap is defined between the second subsection 1125b and the screen module 13. The second gap is filled with a graphite layer 152, while the first gap is filled with a Mylar layer 151. This optimizes the layout of the filling layer 15 and improves the efficiency of the filling material. The area of the second subsection 1125b can be larger than that of the first subsection 1125a, so that the graphite layer 152 can provide a large-area support effect.

[0043] It should be noted that the electronic device 1 can be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted terminal, a medical terminal, etc.

[0044] The above description is merely a preferred embodiment of the present disclosure and does not constitute any form of limitation to the present disclosure. Although the present disclosure has been disclosed as a preferred embodiment as above, it is not intended to limit the present disclosure. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present disclosure.
