[0036] Figure 2 An exploded diagram of an electronic device provided in an embodiment of the present disclosure, such as Figure 2 As shown, the heat sink 3 includes a supporting area 31 , which is configured to support one side of the camera assembly 2 .
[0037] The electronic device provided by the embodiment of the present disclosure includes a camera assembly 2 and a heat sink 3. The support area 31 of the heat sink 3 is configured to support the camera assembly 2. There is no need to support the camera assembly 2 through a middle frame or a steel sheet, which optimizes the internal layout space of the electronic device. In addition, the structure in which the camera assembly 2 is supported by the heat sink 3 is conducive to improving the heat dissipation effect of the camera assembly 2.
[0038] To make the technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be described in further detail below with reference to the accompanying drawings.
[0039] like Figure 1 As shown, the electronic device provided by the embodiment of the present disclosure includes a middle frame 1, a camera assembly 2, and a heat sink 3. The middle frame 1 has a first surface and a second surface facing each other in the thickness direction. The camera assembly 2 is located on the first surface of the middle frame 1, and the heat sink 3 is located on the second surface of the middle frame 1. The camera assembly 2 and the heat sink 3 are respectively fixedly connected to the middle frame 1. The heat sink 3 is opposite to the camera assembly 2 and is thermally connected to the end of the camera assembly 2 away from the lens, thereby dissipating heat from the camera assembly 2.
[0040] It should be noted that the electronic device provided in the embodiments of the present disclosure may be, but is not limited to, a mobile phone, a remote control, a tablet computer, an MP3 player (Moving Picture Experts Group Audio Layer III, Moving Picture Experts Group Audio Layer 3), or an MP4 player (Moving Picture Experts Group Audio Layer IV, Moving Picture Experts Group Audio Layer 4). The electronic device may also be referred to as a user device, a portable terminal, a laptop terminal, or other names. In some embodiments of the present disclosure, the electronic device is an electronic device with a foldable function, such as a foldable mobile phone, and the electronic device includes at least two middle frames 1. In some embodiments of the present disclosure, the electronic device is a non-foldable device, and the electronic device includes one middle frame 1. See Figure 1 The first surface of the middle frame 1 is located on a side close to the rear shell of the foldable electronic device, and the second surface of the middle frame 1 is located on a side close to the display screen of the foldable electronic device.
[0041] In some embodiments of the present disclosure, the heat sink 3 is located on a side of the camera assembly 2 away from the lens, and the support area 31 of the heat sink 3 is thermally connected to the camera assembly 2. For example, the side of the support area 31 close to the camera assembly 2 is connected to the camera assembly 2 via a thermal pad, which can be thermal grease, thermal adhesive, thermal gasket, graphite, etc.
[0042] like Figure 2As shown, the heat sink 3 includes a support area 31, and the middle frame 1 includes a middle plate 11. The support area 31 is located at a corner of the heat sink 3 and corresponds to the installation position of the camera assembly 2 on the middle plate 11. The area of the support area 31 is slightly larger than the area of the end of the camera assembly 2 near the middle plate 11, and the support area 31 can completely cover the end of the camera assembly 2 near the middle plate 11, thereby firmly supporting the camera assembly 2 and providing better heat dissipation for the camera assembly 2.
[0043] In some embodiments of the present disclosure, Figure 2 As shown, the middle plate 11 is provided with a first mounting opening 111 that passes through the first and second surfaces, and the camera assembly 2 is mounted in the first mounting opening 111. The end of the camera assembly 2 that is closest to the middle plate 11 can pass through the first mounting opening 111 and contact the support area 31 of the heat sink 3, thereby dissipating heat from the camera assembly 2.
[0044] In some embodiments of the present disclosure, see Figure 2 The electronic device also includes a battery assembly 4, which is located on the first side of the middle frame 1. The battery assembly 4 is fixedly connected to the middle plate 11. The heat sink 3 also includes a heat sink 32, which is thermally connected to the battery assembly 4. The heat sink 32 of the heat sink 3 is used to dissipate heat from the battery assembly 4.
[0045] Alternatively, as Figure 2 As shown, the middle plate 11 is provided with a second mounting opening 112 that passes through the first and second surfaces, and the battery assembly 4 is mounted within the second mounting opening 112. The second mounting opening 112 reduces the volume occupied by the middle plate 11, thereby providing more space for the battery assembly 4 and facilitating an increase in the capacity of the battery assembly 4. Furthermore, the battery assembly 4 directly contacts the heat sink 32 of the heat sink 3, enhancing the heat dissipation effect of the heat sink 3 on the battery assembly 4.
[0046] In some embodiments of the present disclosure, see Figure 2 , the orthographic projection of the support area 31 on the middle plate 11 covers the first mounting opening 111 ; and / or the orthographic projection of the heat sink 32 on the middle plate 11 covers the second mounting opening 112 .

Figure 3 As shown, the support area 31 can cover the first mounting port 111, and the heat sink 32 can cover the second mounting port 112, thereby completely covering the portion of the camera assembly 2 located in the first mounting port 111 and the portion of the battery assembly 4 located in the second mounting port 112, providing better heat dissipation effect for the battery assembly 4 and the camera assembly 2.
[0048] In some embodiments of the present disclosure, the electronic device further includes a mainboard, and the heat sink 32 can also cover at least a portion of the mainboard, that is, the area of the mainboard where the chip is provided, thereby dissipating heat from the mainboard of the electronic device.
[0049] Optionally, the thickness of the support region 31 is 0.05mm to 0.16mm; and / or the thickness of the heat sink 32 is 0.2mm to 0.5mm. Preferably, the thickness of the support region 31 is 0.12mm, and the thickness of the heat sink 32 is 0.38mm. The appropriate thickness of the support region 31 and the heat sink 32 can increase the strength of the heat sink 3 and prevent it from deforming when the electronic device is dropped or impacted.
[0050] It should be noted that the heat sink 3 provided in the embodiment of the present disclosure is a vacuum chamber heat spreader or a loop heat pipe. Among them, the loop heat pipe (Loop Heat Pipe, abbreviated as LHP in English) is a closed-loop ring-type heat pipe that can perform cyclic heat dissipation and has a good heat dissipation function. The vacuum chamber heat spreader (Vapor Chamber, abbreviated as VC in English) has a vacuum cavity with a microstructure and has a good heat dissipation function. Its materials include but are not limited to copper, stainless steel, titanium alloy, etc. The heat sink 3 may include an upper cover plate and a lower cover plate, and the edge of the upper cover plate is sealed to the edge of the lower cover plate. In the heat sink 32 part, a cavity is formed between the upper cover plate and the lower cover plate, and the cavity is filled with a heat-conducting medium to improve the heat dissipation effect of the battery assembly 4. In the support area 31 part, the upper cover plate and the lower cover plate are completely attached to each other, and there is no cavity between the upper cover plate and the lower cover plate to reduce the thickness of the heat sink 3 at the support area 31. The thickness of the upper cover plate and the lower cover plate can be equal, respectively 0.06mm.

In some embodiments of the present disclosure, such as Figure 4 As shown, the heat sink 3 further includes a skirt region 33. The edge of the heat sink 32 is connected to the edge of the support region 31. The skirt region 33 surrounds the heat sink 32 and the support region 31. The skirt region 33 is formed by the connection between the upper cover plate and the lower cover plate to form a sealed cavity in the heat sink 3.
[0052] In some embodiments of the present disclosure, Figure 4 As shown, a plurality of protrusions 331 are provided at the edge of the skirt area 33 , and the heat sink 3 is welded to the middle frame 1 via the protrusions 331 .
[0053] Alternatively, see Figure 1 The electronic device further includes a colloid 5, through which the skirt region 33 of the heat sink 3 is bonded to the middle frame 1. The colloid 5 may be a conductive colloid, through which the heat sink 3 is connected to the grounding point of the middle frame 1.
[0054] Optionally, the heat sink 3 may also be connected to the middle frame 1 via screws.
[0055] In some embodiments of the present disclosure, Figure 1 As shown, the electronic device further includes a heat conductor 6 and a screen assembly 7.
