[0028] Combine the following Figures 1 to 6 An electronic device 100 according to an embodiment of the present application is described.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, an embodiment of the present application provides an electronic device 100, including: a frame 110; a heat spreader 120, which is arranged on the frame 110; a battery shell 130, which is arranged on the heat spreader 120, and a receiving cavity 190 is formed between the battery shell 130 and the heat spreader 120; and a battery 140, which is arranged in the receiving cavity 190.

[0030] In an embodiment of the present application, the electronic device 100 includes a frame 110, a heat spreader 120, a battery shell 130 and a battery 140. The battery shell 130 is arranged on the heat spreader 120, and the battery shell 130 and the heat spreader 120 surround a accommodating cavity 190. The battery 140 is arranged in the accommodating cavity 190, so that the battery 140 is protected by the battery shell 130 and the heat spreader 120. The heat spreader 120 is arranged on the frame 110, so as to fix the heat spreader 120, the battery 140 and the battery shell 130. Due to the protection of the battery shell 130 and the heat spreader 120, the possibility of the battery 140 being subjected to impact and shock when the electronic device 100 falls or other situations occurs can be reduced, and the possibility of the battery 140 being damaged by external force can be reduced, thereby improving the safety of the battery 140 and improving the safety of the electronic device 100.

[0031] Furthermore, there is no frame 110 between the heat spreader 120 and the battery 140 , which can improve the heat spread effect of the heat spreader 120 on the battery 140 .

[0032] like Figure 3 , Figure 4 and Figure 5 As shown, as a possible implementation, the frame 110 has a mounting hole 112 , the heat spreader 120 is disposed at one end of the mounting hole 112 , and the battery shell 130 passes through the mounting hole 112 .

[0033] Specifically, the frame 110 has a mounting hole 112, and the battery shell 130 passes through the mounting hole 112, thereby reducing the weight of the frame 110 and reducing the weight of the electronic device 100. The battery shell 130 can also play a supporting role to ensure the strength of the electronic device 100. Moreover, the battery shell 130 passes through the mounting hole 112 to reduce the thickness of the electronic device 100.

[0034] The frame 110 is hollowed out at the position corresponding to the battery 140 to form a mounting hole 112. The assembly formed by the battery 140, the battery shell 130 and the heat spreader 120 is mounted at the mounting hole 112 of the frame 110 through the fixing member 150. The heat spreader 120 is a structural member that supports the battery 140. Secondly, the heat spreader 120 will cover the entire mounting hole 112. Compared with the solutions in the related art, the influence of the frame 110 on the heat spreader 120 is reduced, the area of ​​the heat spreader 120 is increased, and the heat dissipation capacity of the electronic device 100 can also be improved. At the same time, the heat dissipation capacity of the electronic device 100 is enhanced, and the use of the Pyrolytic Graphite Sheet (PGS) can be eliminated, reducing costs and reducing the thickness of the electronic device 100. Specifically, the thickness of the electronic device 100 can be reduced by more than 0.11 mm. Among them, the fixing member 150 can be a screw, a rivet or a buckle. The number of the fixing members 150 may be at least two, and the at least two fixing members 150 are respectively disposed on at least two of the first plate 1162 , the second plate 1164 , and the frame 114 .

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, as a possible implementation, the frame 110 includes: a frame 114 ; a plate 116 located inside the frame 114 , the mounting hole 112 is located in the plate 116 , and the heat spreader 120 is fixed to the plate 116 .

[0036] Specifically, the frame 110 includes a frame 114 and a plate 116 . The plate 116 is arranged inside the frame 114 , the mounting hole 112 is arranged on the plate 116 , and the heat equalizing member 120 is fixed on the plate 116 to ensure that the heat equalizing member 120 can equalize the heat of components such as circuit boards or cameras arranged on the plate 116 .

[0037] like Figure 5 As shown, as a possible implementation, the plate body 116 includes: a first plate body 1162; a second plate body 1164, which is located on one side of the first plate body 1162, the mounting hole 112 is located between the first plate body 1162 and the second plate body 1164, and the heat equalizing member 120 is in contact with the first plate body 1162 and the second plate body 1164.

[0038] Specifically, the plate body 116 includes a first plate body 1162 and a second plate body 1164. The first plate body 1162 and the second plate body 1164 are arranged at intervals in the frame body 110. A mounting hole 112 is formed between the first plate body 1162 and the second plate body 1164. The first plate body 1162 can be used to install components such as a motherboard, a camera, a speaker or an antenna. Similarly, the second plate body 1164 can be used to install components such as a motherboard, a camera, a speaker or an antenna. The first plate body 1162 and the second plate body 1164 are both in contact with the heat equalizing member 120, thereby enhancing the heat equalizing effect of the heat equalizing member 120, so that the heat on the first plate body 1162 and the second plate body 1164 can be heat equalized through the heat equalizing member 120, which helps to dissipate heat of the electronic device 100 and improves the performance of the electronic device 100.

[0039] Among them, by setting the mounting hole 112 on the plate body 116, the restriction of the plate body 116 on the heat spreader 120 is reduced, the heat dissipation area of ​​the heat spreader 120 is increased, and the heat dissipation capacity of the electronic device 100 is improved. Moreover, as the heat dissipation capacity of the electronic device 100 is enhanced, the use of the graphite film can be eliminated and the thickness of the electronic device 100 can be reduced.

[0040] like Figure 3 and Figure 4 As shown, as a possible implementation, it also includes: a fixing member 150 that passes through the frame 110 and is connected to the heat dissipating member 120 .

[0041] Specifically, the electronic device 100 also includes a fixing member 150, which passes through the frame 110 and is connected to the heat spreader 120, thereby reducing the degree of protrusion of the fixing member 150 on the side of the heat spreader 120 away from the battery shell 130, or the fixing member 150 does not form a protrusion on the side of the heat spreader 120 away from the battery shell 130, thereby facilitating the setting of the screen assembly 160 or other components.

[0042] Furthermore, when the battery 140 needs to be replaced or repaired, the battery 140 can be disassembled by simply removing the fixing part 150, without the need to remove the glue from the frame 110 or other operations. Moreover, when replacing the battery 140, the battery 140, the battery shell 130 and the heat spreader 120 can be directly replaced, thereby increasing the speed of replacing and repairing the battery 140.

[0043] like Figure 4 As shown, as a possible implementation, it also includes: a screen assembly 160, which is disposed on the frame 110, and the screen assembly 160 and the heat spreader 120 are in contact with each other.

[0044] Specifically, the electronic device 100 further includes a screen assembly 160 , which is disposed on the frame 110 . The screen assembly 160 and the heat spreader 120 are in contact with each other, thereby helping to reduce the thickness of the electronic device 100 and facilitating heat dissipation of the electronic device 100 .

[0045] The screen assembly 160 and the heat spreader 120 are bonded together, and a graphite film is no longer arranged between the screen assembly 160 and the heat spreader 120 , thereby reducing the thickness of the electronic device 100 .

[0046] like Figure 1 As shown, as a possible implementation, it also includes: a camera decoration 170, at least a portion of the camera decoration 170 is located on the side of the battery shell 130 away from the heat spreader 120.

[0047] Specifically, the electronic device 100 also includes a camera decoration 170, and at least part of the camera decoration 170 is located on the side of the battery shell 130 away from the heat spreader 120, that is, at least part of the camera decoration 170 and the battery shell 130 are stacked, which is beneficial to increase the volume of the battery shell 130 or the camera decoration 170, that is, it is beneficial to increase the volume of the battery 140 and the camera, so that the electronic device 100 has a longer battery life and a better shooting effect.

[0048] Due to the existence of the battery shell 130 , when the electronic device 100 falls, the camera decoration 170 can only cause impact to the battery shell 130 , and the battery 140 can be better protected, thereby improving the safety of the electronic device 100 .

[0049] That is, the battery case 130 is used to improve the reliability of the protection of the battery 140, and the safety of the battery 140 of the electronic device 100 is improved. At the same time, the design of the camera decoration 170 can be more flexible, so that it can be placed overlapping with the battery 140. Specifically, Figure 1 As shown, Figure 1 Part of the camera decoration 170 and part of the battery shell 130 are overlapped at A in the figure.

[0050] As a possible implementation manner, the thickness of the battery shell 130 is between 0.1 mm and 0.2 mm, for example, 0.1 mm, 0.13 mm, 0.15 mm, 0.17 mm or 0.2 mm.

[0051] Specifically, the battery 140 is wrapped by a concave battery shell 130 with an installation cavity, and the battery 140 is bonded to the heat spreader 120 through the colloid 180. The battery shell 130 and the heat spreader 120 are connected by electric welding, so that the heat spreader 120, the battery 140 and the battery shell 130 are combined into one component. In this case, the battery 140 and the camera decoration 170 can be stacked. When the camera decoration 170 is dropped or hit, so that external force is transmitted to the battery 140 through the camera decoration 170, the battery shell 130 can play a protective role, thereby improving the safety and reliability of the battery 140.

[0052] like Figure 6 As shown, as a possible implementation, the battery shell 130 is recessed on one side facing the heat spreader 120 to form a receiving cavity 190 . The heat spreader 120 is plate-shaped and is covered on the battery shell 130 to seal the receiving cavity 190 .

[0053] Specifically, the heat equalizing member 120 is in the shape of a plate, and the battery shell 130 is recessed on one side toward the heat equalizing member 120 to form a accommodating cavity 190. The heat equalizing member 120 is covered on the battery shell 130 to seal the accommodating cavity 190. Since the heat equalizing member 120 usually has a heat conduction channel, it is configured in the shape of a plate to facilitate the production and manufacturing of the heat equalizing member 120.

[0054] like Figure 3 and Figure 4 As shown, as a possible implementation, the battery 140 is bonded to the heat spreader 120 via the colloid 180 ; the colloid 180 covers the side of the battery 140 facing the heat spreader 120 .

[0055] Specifically, the battery 140 is bonded to the heat spreader 120 by the colloid 180, so that the battery 140 and the heat spreader 120 are firmly connected together, ensuring the heat dissipation effect of the heat spreader 120 on the battery 140, and the colloid 180 covers the side of the battery 140 facing the heat spreader 120, thereby improving the firmness of the battery 140 and the heat spreader 120 and reducing the possibility of the battery 140 being subjected to force and movement. In addition, bonding the battery 140 and the heat spreader 120 by the colloid 180 can reduce the difficulty of assembling the battery 140 and the heat spreader 120.

[0056] Moreover, with such a design, there is no flexible printed circuit (FPC) wiring between the battery 140 and the heat spreader 120, thereby increasing the area of ​​the heat spreader 120 used to fix the battery 140, that is, increasing the fitting area between the heat spreader 120 and the battery 140, thereby improving the stability and heat dissipation effect of the battery 120.

[0057] As a possible implementation, the battery housing 130 and the heat spreader 120 are connected by welding.

[0058] Specifically, the battery shell 130 and the heat spreader 120 are connected by welding to ensure the reliability of the connection between the heat spreader 120 and the battery shell 130 , ensure the protective effect of the battery shell 130 and the heat spreader 120 on the battery 140 , and facilitate the positioning of the battery shell 130 inside the electronic device 100 .

[0059] As a possible implementation, the battery shell 130 may be made of metal. The metal battery shell 130 may provide a higher protection effect and also play a certain heat dissipation role. Specifically, the battery shell 130 may be made of steel or copper.

[0060] As a possible implementation, the heat spreader 120 may be a vacuum chamber (VC) heat spreader or a metal heat sink.

[0061] The battery 140 is bonded to one side of the heat spreader 120 by the colloid 180, which greatly increases the adhesive area between the battery 140 and the heat spreader 120, effectively reducing the possibility of movement of the battery 140, and when the battery 140 needs to be replaced or repaired, the entire assembly can be removed by removing the fixing member 150, without the need to disassemble the battery 140 through the handle. The operation of replacing or repairing the battery 140 is simpler and more effective, and will not cause pulling and deformation to the flexible circuit board.

[0062] Furthermore, since the battery 140 is taken out by disassembling the fixing member 150, the handle design of the battery 140 can be eliminated, which is conducive to reducing the thickness of the electronic device 100. Specifically, the thickness can be reduced by more than 0.06mm×2mm=0.12mm. Among them, 0.06mm is the thickness of the single-layer handle, and the thickness of the double-layer handle is 0.12mm.

[0063] As above, as Figures 1 to 6 As shown, the electronic device 100 provided in the present application wraps the battery 140 with the battery shell 130, which can improve the reliability of protecting the battery 140, and the design of the camera decoration 170 and the battery 140 has better freedom.

[0064] Furthermore, the heat spreader 120 has two functions: first, it serves as a structural member to fix the battery 140 , and second, it serves as a heat sink to dissipate heat, thereby improving the heat dissipation capability of the electronic device 100 .

[0065] The maintenance of the electronic device 100 is simpler and more effective, and the battery 140 can be replaced by disassembling the fixing member 150 .

[0066] Furthermore, the frame 110 is provided with a mounting hole 112 to reduce the influence of the frame 110 on the heat spreader 120, thereby increasing the area of ​​the heat spreader 120, thereby reducing the use of graphite film and reducing the thickness of the electronic device 100. In addition, the handle design of the battery 140 can be eliminated, and the thickness of the electronic device 100 can be further reduced to achieve a light and thin design of the electronic device 100. Specifically, the thickness of the electronic device 100 can be reduced by more than 0.11mm+0.12mm-0.15mm=0.08mm, wherein 0.11mm is the thickness of the graphite film, 0.12mm is the thickness of the handle of the battery 140, and 0.15mm is the thickness of the battery shell 130. If a thinner battery shell 130 is used, the thickness of the electronic device 100 can be further reduced.

[0067] The electronic device 100 may be a terminal or other device except the electronic device 100. For example, the electronic device 100 may be a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a music player, a private network communication terminal device (such as a walkie-talkie), a mobile Internet device (Mobile Internet Device, MID), an augmented reality / virtual reality / mixed reality device, a robot, a wearable device, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook or a personal digital assistant (personal digital assistant, PDA), etc. It may also be a server, a network attached storage (Network Attached Storage, NAS), a personal computer (personal computer, PC), a television (television, TV), a teller machine or a self-service machine, etc., and the embodiments of the present application are not specifically limited.

[0068] In the description of this specification, the description with reference to the terms "one embodiment" or "specific embodiment" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0069] Although the embodiments of the present application have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the claims and their equivalents.
