[0042] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] In related technologies, such as Figure 5 As shown, electronic devices typically include a mid-frame assembly 1, a battery assembly 2, a heat spreader 3, and an FPC cable 4. The mid-frame assembly 1 includes an outer frame 11 and a mid-plate 12. The battery assembly 2 is fixed to the mid-plate 12, and the electronic components on both sides of the battery assembly 2 are electrically connected via the FPC cable 4. The mid-plate 12 has mounting holes 121, and the heat spreader 3 is fixed within these holes, attached to the motherboard and adjacent to the battery assembly 2, to transfer heat from the motherboard to the mid-plate 12 and the battery assembly 2, thereby achieving heat dissipation for the motherboard. In a specific arrangement, the heat spreader 3, battery assembly 2, and FPC cable 4 are stacked, with the battery assembly 2 and FPC cable 4 located on the same side of the heat spreader 3, and the FPC cable 4 positioned between the battery assembly 2 and the heat spreader 3.

[0045] However, in the above structure, since the FPC cable 4 has a certain thickness, it will occupy the space of the middle plate 12 near the battery component 2 in the overlapping direction, which will limit the size of the battery component 2 and thus limit the capacity of the battery component 2.

[0046] This disclosure provides an electronic device, such as... Figure 1As shown, the electronic device includes a middle frame assembly 1, a battery assembly 2, a vapor chamber 3, and an FPC cable 4. The middle frame assembly 1 includes a frame 11 and a middle plate 12 connected to each other, and the middle plate 12 has a mounting hole 121. The battery assembly 2 is located on one side of the middle plate 12 and connected to the middle plate 12. The vapor chamber 3 includes a main body 31 and a protruding part 32 connected to each other, and the main body 31 and the protruding part 32 are both located in the mounting hole 121. The main body 31 is connected to the middle plate 12, the protruding part 32 is located on the side of the main body 31 close to the battery assembly 2, and there is a gap between the protruding part 32 and the inner wall of the mounting hole 121. The protruding part 32 is attached to the battery assembly 2. At least part of the FPC cable 4 is located in the gap.

[0047] By using the electronic device provided by the embodiment of the present disclosure, the FPC cable 4 can be placed between the protruding part 32 and the inner wall of the mounting hole 121, that is, the FPC cable 4 is located in the mounting hole 121, thereby reducing or avoiding the FPC cable 4 occupying the space on the side of the middle plate 12 close to the battery assembly 2 in the arrangement direction of the battery assembly 2 and the middle plate 12, and further increasing the size of the battery assembly 2 and improving the capacity of the battery assembly 2.

[0048] It should be noted that the middle plate 12 is improved in the embodiment of the present disclosure. By comparing Figure 1 and Figure 5 , it can be found that, compared with the related art, the mounting hole 121 on the middle plate 12 in the embodiment of the present disclosure has a larger size, so as to ensure that the protruding part 32 has a sufficient size to ensure that the vapor chamber 3 can fully dissipate heat.

[0049] It should be noted that "at least part of the FPC cable 4 is located in the gap" can include "the part of the FPC cable 4 between the middle plate 12 and the battery is entirely within the surface on the side of the middle plate 12 close to the battery assembly 2"; or "at least part of the FPC cable 4 is located in the gap" can also include "the part of the FPC cable 4 between the middle plate 12 and the battery, part of which is within the surface on the side of the middle plate 12 close to the battery assembly 2, and part of which is outside the surface".

[0050] It should be noted that the type of electronic device is not limited in the embodiment of the present disclosure. For example, the electronic device can be a mobile phone or a tablet computer.

[0051] The electronic device provided by the embodiment of the present disclosure will be explained below in combination with some examples.

[0052] In some examples, the vapor chamber 3 can be a VC (Vapor Chamber) plate made of a metal material, and there is a cavity inside the VC plate, and the cavity has a heat exchange medium to transfer heat through the flow of the heat exchange medium.

[0053] Further, since the heat exchange medium needs to be injected into the VC plate, the VC plate often has a heat exchange medium inlet. After the heat exchange medium is injected, the heat exchange medium inlet needs to be closed. After the heat exchange medium inlet is closed, some burrs will inevitably appear on the surface of the VC plate. In the related art, the heat exchange medium inlet is often arranged on the side close to the battery. As shown in Figure 5 , the FPC flat cable 4 often directly contacts the vapor chamber 3, and the FPC flat cable 4 itself is easily punctured by the burrs on the vapor chamber 3. Therefore, a protective layer (for example, Mylar) needs to be arranged on the burrs.

[0054] Compared with the prior art, after the electronic device provided in the embodiments of the present application is used, the FPC flat cable 4 is placed between the protruding portion 32 and the inner wall of the mounting hole 121, and the FPC flat cable 4 does not contact the burrs on the vapor chamber 3. Therefore, the protective layer does not need to be arranged on the burrs, and the cost of arranging the protective layer can be saved.

[0055] In some examples, as shown in Figure 1 , the first side wall 32a of the protruding portion 32 and the first inner wall 121a of the mounting hole 121 have a first interval, and the second side wall 32b of the protruding portion 32 and the second inner wall 121b of the mounting hole 121 have a second interval. The FPC flat cable 4 includes a first portion 41 and a second portion 42 arranged at intervals, and the first portion 41 and the second portion 42 are respectively located in the first interval and the second interval.

[0056] The relative two sides of the protruding portion 32 and the inner wall have the first interval and the second interval, so that the protruding portion 32 is located close to the middle of the mounting hole 121, and the uniformity of temperature distribution at different positions in the electronic device is improved.

[0057] The first portion 41 and the second portion 42 can be used to connect different electronic elements. The FPC flat cable 4 is divided into two portions, and the two portions are respectively placed in the first interval and the second interval. The electronic elements in the electronic device can be arranged conveniently. For example, the first portion 41 is used to connect a mainboard and a display screen of the electronic device, and the second portion 42 is used to connect the mainboard and a loudspeaker located on the other side of the battery assembly 2.

[0058] Further, the distance of the first interval and the second interval is respectively a and b, and 6mm≤a+b≤10mm.

[0059] If the size of a+b is too small, the FPC flat cable 4 cannot be placed in the two intervals completely. If the size of a+b is too large, the size of the protruding portion 32 is too small, and the heat transfer of the vapor chamber 3 is affected. The size of a+b is in the range, so that the two portions of the FPC flat cable 4 can be placed in the first interval and the second interval, and the size of the first interval and the second interval is prevented from being too large, and the heat transfer effect of the vapor chamber 3 is affected.

[0060] wherein the value of [a, b] is mainly determined by the size of the first part 41 and the second part 42, and the value of [a, b] can be [3mm, 5mm], [3mm, 6mm], [4mm, 4mm], [4mm, 5mm], [4mm, 6mm] or [5mm, 5mm].

[0061] In some examples, as shown in FIG. 6, one side of the protruding part 32 has a fifth interval with the inner wall of the mounting hole 121, and the other side has a safety gap reserved with the inner wall of the mounting hole 121, and the FPC flat cable 4 is located in the fifth interval. The distance of the fifth interval is c, and 6mm≤c≤10mm, and the distance of the safety gap is between 0.05mm and 0.15mm. Figure 3

[0062] wherein if the size of c is too small, it is difficult to put the FPC flat cable 4 into the fifth interval, and if the size of c is too large, it may cause the size of the protruding part 32 to be too small, which is not conducive to the heat transfer of the vapor chamber 3. By adopting such a value range, it can not only ensure that the FPC flat cable 4 is put into the fifth interval, but also prevent the size of the fifth interval from being too large, which affects the heat transfer effect of the vapor chamber 3.

[0063] wherein in the use process, the protruding part 32 may be deformed, and by setting the safety gap, it can prevent the protruding part 32 from being extruded with the inner wall of the mounting hole 121, causing further deformation, thereby improving the stability of the structure of the vapor chamber 3.

[0064] In some examples, as shown in FIG. 6, in the thickness direction of the middle plate 12, the size of the main body part 31 is h1, and the size of the protruding part 32 is h2, and 0.3mm≤h1+h2≤0.4mm. Figure 1

[0065] wherein if h1+h2 is too small, it is not conducive to the heat transfer of the vapor chamber 3, and if h1+h2 is too large, it will cause the size of the vapor chamber 3 to be too large, which is not conducive to the layout inside the electronic device on the one hand, and will cause the weight of the electronic device to be too large on the other hand. By setting h1+h2 in this range, it can not only ensure the heat transfer effect of the vapor chamber 3, but also prevent the weight of the electronic device from being too large.

[0066] For example, when the vapor chamber 3 is a VC plate, if h1+h2 is too small, it is not conducive to the flow of the heat exchange medium inside the vapor chamber 3.

[0067] In some examples, as shown in FIG. 6, the inner wall of the mounting hole 121 has a limiting step 122, and the limiting step 122 is connected with the main body part 31. Figure 1

[0068] ​​​Wherein, since the thickness of the vapor chamber 3 is usually small, directly connecting the side wall of the vapor chamber 3 with the edge of the mounting hole 121 can hardly guarantee the stability of the connection, and is inconvenient for installation. By connecting the main body 31 with the edge of the mounting hole 121 through the limiting step 122, the contact area between the edge of the mounting hole 121 and the main body 31 can be increased, so that the stability of the installation of the vapor chamber 3 can be greatly improved, and the convenience of the installation of the vapor chamber 3 can also be greatly improved.

[0069] For example, the width of the limiting step 122 can be between 1mm and 2mm.

[0070] In some examples, as shown in Figure 3 The surface of the main body 31 away from the battery assembly 2 and the surface of the middle plate 12 away from the battery assembly 2 have a height difference h3 of 0.08mm≤h3≤0.1mm.

[0071] Wherein, the vapor chamber 3 may be deformed during use, thereby pressing the electronic devices on the side of the middle plate 12 away from the battery assembly 2, such as a display screen. By setting such a height difference, the above situation can be avoided, thereby preventing the electronic components inside the electronic device from being damaged.

[0072] For example, under the effect of thermal expansion and contraction, the vapor chamber 3 may expand, thereby pressing the electronic devices on the side of the middle plate 12 away from the battery assembly 2.

[0073] In some examples, the FPC flat cable 4 is fixedly connected with the main body 31.

[0074] In the related art, when the FPC flat cable 4 is arranged, the FPC flat cable 4 needs to be fixed. For example, in the technical solution in Figure 5 In order to avoid increasing the thickness of the adhesive layer between the battery assembly 2 and the FPC flat cable 4, the FPC flat cable 4 is often pre-bent, and the part of the FPC flat cable 4 between the battery assembly 2 and the vapor chamber 3 is limited in the corresponding position by the battery assembly 2 and the vapor chamber 3, so as to realize glue-free bonding. This will cause the FPC flat cable 4 to need to be slightly lengthened for pre-bending, thereby increasing the impedance of the FPC flat cable 4, and under the influence of tolerance and assembly process, the FPC flat cable 4 will inevitably have problems of warping or poor bonding.

[0075] Compared with the related art, the electronic device provided by the embodiments of the present disclosure can fix the FPC flat cable 4 by bonding the FPC flat cable 4 to the vapor chamber 3, since the FPC flat cable 4 is located in the interval between the vapor chamber 3 and the mounting hole 121. Compared with Figure 5The technical solution embodied not only avoids increasing the thickness of the battery assembly 2 due to the adhesive fixing of the FPC flat cable 4 on the side of the middle plate 12 close to the battery, but also avoids the problems of the FPC flat cable 4 being warped or poorly attached.

[0076] Based on the same concept, the embodiment of the present disclosure also provides an electronic device, as shown in the figure Figure 4 As shown in the figure, the electronic device includes a middle frame assembly 1, a battery assembly 2, a vapor chamber 3, and an FPC flat cable 4. The middle frame assembly 1 includes a connected outer frame 11 and a middle plate 12, and the middle plate 12 has a mounting hole 121. The battery assembly 2 is located on one side of the middle plate 12 and is connected to the middle plate 12. The vapor chamber 3 includes a main body 31 and a plurality of protruding portions 32 connected to each other, and the main body 31 and the plurality of protruding portions 32 are located in the mounting hole 121. The main body 31 is connected to the middle plate 12, and the plurality of protruding portions 32 are located on the side of the main body 31 close to the battery assembly 2 and are attached to the battery assembly 2. There is a gap between adjacent two of the plurality of protruding portions 32. At least part of the FPC flat cable 4 is located in the gap.

[0077] The electronic device provided by the embodiment of the present disclosure can place the FPC flat cable 4 between the plurality of protruding portions 32, that is, the FPC flat cable 4 is located in the mounting hole 121, thereby reducing or avoiding the FPC flat cable 4 occupying the space on the side of the middle plate 12 close to the battery assembly 2 in the arrangement direction of the battery and the middle plate 12, and thereby increasing the size of the battery assembly 2 and improving the capacity of the battery assembly 2.

[0078] In some examples, the plurality of protruding portions 32 includes a first protruding portion 321, a second protruding portion 322, and a third protruding portion 323 adjacent in turn, and there is a third gap between the first protruding portion 321 and the second protruding portion 322, and there is a fourth gap between the second protruding portion 322 and the third protruding portion 323. The FPC flat cable 4 includes a first portion 41 and a second portion 42 arranged in a gap, and the first portion 41 and the second portion 42 are located in the third gap and the fourth gap, respectively.

[0079] The FPC flat cable 4 is divided into two parts and placed in the third gap and the fourth gap, respectively, which can facilitate the arrangement of electronic elements inside the electronic device.

[0080] Further, the distances of the third gap and the fourth gap are d and e, respectively, and 6mm≤d+e≤10mm.

[0081] If the size of d+e is too small, it is difficult to put the FPC flat cable 4 into the two intervals, and if the size of d+e is too large, it can cause the size of the protruding part 32 to be too small, which is not conducive to the heat transfer of the vapor chamber 3. By adopting such a range of values, it can not only ensure that the two parts of the FPC flat cable 4 are put into the third interval and the fourth interval, but also prevent the size of the third interval and the fourth interval from being too large, which affects the heat transfer effect of the vapor chamber 3.
