Figure 2 An exploded view showing a partial structure of an electronic device 100 according to an embodiment of the present invention is shown below. Figure 1 and Figure 2 Provide a detailed description.

[0034] like Figure 1 and Figure 2As shown, electronic device 100 may be a camera and includes a mainboard 110, a first communication chip 120, a second communication chip 130, a first antenna 140, a second antenna 150, and a motor 160. The first communication chip 120 and the second communication chip 130 may also be two functional modules integrated on the same chip 170, which is connected to the upper side of the mainboard 110. In some embodiments, the first communication chip 120 and the second communication chip 130 may be independent chips, each of which is connected to the upper side of the mainboard 110. The first antenna 140 and the second antenna 150 are each connected to the upper side of the mainboard 110. The first antenna 140 is coupled to the first communication chip 120. The first communication chip 120 can transmit or receive wireless signals via the first antenna 140. For example, the first communication chip 120 may be a WiFi chip, which can receive or transmit 2.4 GHz WiFi signals or 5 GHz WiFi signals via the first antenna 140. The second antenna 150 is coupled to the second communication chip 130. The second communication chip 130 can transmit or receive wireless signals through the second antenna 150. For example, the second communication chip 130 can be a WiFi / BT chip. The second communication chip 130 can receive or transmit 2.4GHz Wi-Fi signals through the second antenna 150, or can receive or transmit 2.4GHz Bluetooth signals through the second antenna 150. The motor 160 is arranged between the first antenna 140 and the second antenna 150. The motor 160 can shield at least part of the signals transmitted by the first antenna 140 and the second antenna 150, thereby reducing interference between the first antenna 140 and the second antenna 150, thereby improving the stability of communication. Optionally, the electronic device 100 can also be an electric toothbrush, an electric shaver, a smart speaker, a mobile phone, a tablet computer, etc., but the present invention is not limited to this.

[0035] According to one embodiment of the present invention, Figure 1 As shown, the first antenna 140 and the second antenna 150 can be respectively arranged on both sides of the mainboard 110 to maximize the distance between the first antenna 140 and the second antenna 150, thereby reducing the interference between the first antenna 140 and the second antenna 150. Figure 1 In the illustrated embodiment, the first antenna 140 is disposed at the left edge of the mainboard 110, and the second antenna 150 is disposed at the right edge of the mainboard 110. Optionally, the first antenna 140 and / or the second antenna 150 are metal sheets, and the first antenna 140 and the second antenna 150 can be connected to the mainboard 110 by welding.

[0036] According to one embodiment of the present invention, Figure 1 As shown, the electronic device 100 further includes a housing 180 ( Figure 1 Only a portion of the housing 180 is shown. The motherboard 110 and the motor 160 are both disposed within the housing 180 and are fixedly connected to the housing 180 by screws or other fasteners. Optionally, the output shaft of the motor 160 extends outside the housing 180 and is connected to another portion of the electronic device 100 (e.g., the base), so that the motor 160 can drive the housing 180 to rotate about its output shaft.

[0037] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, the electronic device 100 may further include a metal heat sink 190, which is disposed on the upper side of the mainboard 110. The metal heat sink 190 can absorb the heat generated by the mainboard 110 and other electronic components, and dissipate the heat to the surrounding environment through its large surface area, thereby preventing the mainboard 110 and other electronic components from overheating and preventing the mainboard 110 and other electronic components from being degraded or damaged due to overheating. Figure 1 and Figure 2 As shown, at least a portion of the metal heat sink 190 is located between the first antenna 140 and the second antenna 150 to shield at least part of the signals transmitted by the first antenna 140 and the second antenna 150, thereby reducing interference between the first antenna 140 and the second antenna 150 and improving communication stability.

[0038] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, the metal heat sink 190 may include a first heat dissipation portion 191 and one or more connecting portions 192. The first heat dissipation portion 191 is generally parallel to the mainboard 110. The connecting portions 192 are integrally formed at the edge of the first heat dissipation portion 191 and connected to the sub-mainboard 110 via fasteners such as screws. Optionally, a portion of the first heat dissipation portion 191 extends between the first antenna 140 and the second antenna 150. Optionally, at least one connecting portion 192 is located between the first antenna 140 and the second antenna 150.

[0039] According to one embodiment of the present invention, Figure 1 and Figure 2As shown, the metal heat sink 190 may further include one or more second heat sinks 193, which are integrally formed on the edge of the first heat sink 191. The second heat sink 193 and the first heat sink 191 form a preset angle, for example, the second heat sink 193 and the first heat sink 191 are perpendicular to each other. By providing the second heat sink 193, the heat dissipation area of ​​the metal heat sink 190 can be increased, and the heat dissipation efficiency of the metal heat sink 190 can be improved, which is conducive to preventing the motherboard 110 and other electronic components from overheating, thereby avoiding the motherboard 110 and other electronic components from being degraded or damaged due to overheating. Optionally, at least one second heat sink 193 is located between the first antenna 140 and the second antenna 150 to further improve the signal shielding effect of the metal heat sink 190, thereby reducing the interference between the first antenna 140 and the second antenna 150, and thus improving the stability of communication.

[0040] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, a portion of the metal heat sink 190 extends below the motor 160. A thermal pad is disposed between the motor 160 and the metal heat sink 190. The thermal pad can direct heat generated by the motor 160 to the metal heat sink 190, thereby improving the heat dissipation efficiency of the motor 160. Alternatively, the thermal pad can be made of thermally conductive silicone, thermally conductive silicone grease, or a thermally conductive phase change material.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
