[0047] To make the objectives, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0048] On the one hand, as shown in combination with Figure 1 and Figure 2 this embodiment provides a functional module, and the functional module is close to the antenna radiator 3 of the electronic device.

[0049] The functional module includes: a module body 1 and a metal foil 2, and the metal foil 2 is located on at least one surface of the module body 1; the metal foil 2 includes at least two ground return structures 21, and the at least two ground return structures 21 extend outward in different directions respectively, and the at least two ground return structures 21 are grounded respectively.

[0050] In the functional module of this embodiment, since there is a metal foil 2 on at least one surface of the module body 1 and it is close to the antenna radiator 3, when the antenna radiator 3 works, an induced current will be generated in the metal foil 2. Affected by the at least two ground return structures 21, the induced current is dispersed and then flows along at least two current paths to the two ground return structures 21 respectively. The dispersion of the induced current is beneficial to reducing the clutter interference of the metal foil 2 on the antenna radiator 3, thereby solving the influence of the functional module on the antenna performance.

[0051] Exemplarily, the metal foil 2 further includes an adhering structure 22, and the adhering structure 22 is arranged on the surface of the module body 1, which can simultaneously play the roles of signal shielding and heat dissipation. Exemplarily, the metal foil 2 is a composite material of metal copper and graphite material, and has conductive and heat-conducting characteristics.

[0052] Exemplarily, the number of the ground return structures 21 is, for example, two, three, four, etc.

[0053] In addition, by arranging at least two ground return structures 21, the area of the metal foil 2 can also be increased, which is beneficial to further improving the signal shielding and heat dissipation effects of the module body 1.

[0054] As shown in combination with Figure 1 In some embodiments, the metal foil 2 is located on the back of the module body 1, and the metal foil 2 is used to increase the heat dissipation area of the module body 1.

[0055] By arranging the metal foil 2 on the back of the module body 1, the heat dissipation area of the back of the module body 1 can be increased, and the heat dissipation effect of the module body 1 can be improved.

[0056] In some embodiments, the extension length of at least one of the at least two ground return structures 21 is less than or equal to a first target value. When the extension length of the ground return structure 21 is less than or equal to the first target value, it can ensure that the metal foil 2 is grounded at a short distance, which is beneficial to reducing the electrical length of the induced current, thereby reducing the clutter interference of the metal foil 2 on the antenna radiator 3.

[0057] Exemplarily, the first target value can be determined according to the stacking environment of the metal foil 2. For example, the first target value is the distance between the ground return point closest to the metal foil 2 and the metal foil 2. When the extension length of one of the ground return structures 21 is equal to the first target value, the metal foil 2 can be grounded nearby.

[0058] In some embodiments, the module body 1 is a camera, a sensor, a receiver or a speaker. The above functional devices are all relatively common functional devices in electronic devices, and they may all be arranged near the antenna radiator. When the functional module of the embodiment of the present invention is adopted, the clutter influence of the functional module on the antenna can be reduced, which is beneficial to improving the stacking efficiency of the electronic device.

[0059] The camera can be a front camera, a rear camera, an infrared camera, a natural light camera, a wide-angle camera, etc. The sensor can be a proximity sensor, a brightness sensor, a distance sensor, etc.

[0060] On the other hand, as shown in combination with Figure 3 and Figure 4 This embodiment provides an electronic device, and the electronic device includes the functional module of the present invention.

[0061] The electronic device of this embodiment adopts the functional module of the present invention and has all the beneficial technical effects of all the embodiments herein.

[0062] As shown in combination with Figure 3As shown, in some embodiments, the electronic device further includes an antenna radiator 3; the antenna radiator 3 is close to the functional module. The functional module can achieve grounding by using at least two grounding structures 21, without affecting the working performance of the antenna radiator 3.

[0063] Combined with Figure 3 As shown, in some embodiments, the electronic device further includes a main board module 4, and the functional module is located on one side of the main board module 4; the main board module 4 includes a shielding cover 41, and at least one of the at least two grounding structures 21 is connected to the shielding cover 41.

[0064] In this embodiment, the main board module 4 is the core component of the electronic device, equivalent to the "brain" of the electronic device, responsible for processing all information and controlling all functions. The main board module 4 is based on a circuit board, on which a processor, a memory, a storage chip, a communication chip, a power management chip, an audio decoding chip, a display chip, and various interfaces are respectively integrated, and so on.

[0065] In order to shield the electromagnetic radiation and interference of electronic components such as the processor in the main board module 4, a shielding cover 41 is covered on the electronic components. Exemplarily, the shielding cover 41 is made of a metal material, such as copper, aluminum, iron, etc., and is designed as a covering layer matching the main board module 4. The shielding cover 41 is directly welded to the circuit board of the main board module 4 and is grounded. The shape and size of the shielding cover 41 depend on the design of the main board module 4.

[0066] In the electronic device, the functional module needs to be connected to the main board module 4, and the main board module 4 provides electrical energy for it and conducts data exchange. Therefore, in this embodiment, the functional module is located on one side of the main board module 4, and at least one grounding structure 21 is connected to the shielding cover 41, so that the grounding of the metal foil 2 can be achieved by using the shielding cover 41.

[0067] Combined with Figure 3 and Figure 4 As shown, in some embodiments, the main board module 4 further includes a connection component 42, and the connection component 42 is used to fix the main board module 4; at least one of the at least two grounding structures 21 is connected to the connection component 42.

[0068] In this embodiment, the main board module 4 can be fixedly connected to the middle frame by using the connection component 42. Therefore, by connecting the grounding structure 21 to the connection component 42, the grounding of the metal foil 2 can be achieved.

[0069] Combined with Figure 4 As shown, in some embodiments, the electronic device includes a middle frame support part 5, the middle frame support part 5 is a part of the middle frame of the electronic device, and the connection component 42 is connected to the middle frame support part 5, so as to realize the fixed connection between the main board module 4 and the middle frame.

[0070] Combined withFigure 4 As shown, in some embodiments, the connection component 42 includes a spacer 421 and a screw member 422.

[0071] The spacer 421 is located between the main board module 4 and the middle frame support portion 5, and the screw member 422 is threadedly connected through the main board module 4, the spacer 421, and the middle frame support portion 5; the ground return structure 21 connected to the connection component 42 extends between two adjacent ones of the main board module 4, the spacer 421, and the middle frame support portion 5. The spacer 421 is made of a metal material.

[0072] With the above arrangement, by using the screw member 422 to press the ground return structure 21, the ground return of the metal foil 2 can be achieved. Exemplarily, the ground return structure 21 extends between the main board module 4 and the spacer 421, and the ground return structure 21 is connected to the middle frame support portion 5 through the spacer 421, and the middle frame support portion 5 provides the ground return potential. Another example is that the ground return structure 21 extends between the spacer 421 and the middle frame support portion 5, and the ground return structure 21 is directly connected to the middle frame support portion 5, and the middle frame support portion 5 provides the ground return potential.

[0073] Exemplarily, referring to Figure 1 or Figure 2 , the end of the ground return structure 21 has a hole-shaped structure, which can be used to pass through the screw member 422.

[0074] In some embodiments, the spacer 421 is a surface mount structure (or surface mount component) on the upper surface of the main board module 4.

[0075] In this embodiment, the surface mount structure is a component installed by SMT (Surface Mount Technology). By directly mounting the spacer 421 on the surface of the main board module 4 and then welding, the assembly of the spacer 421 is achieved.

[0076] Combined with Figure 3 As shown, in some embodiments, the module body 1 is a front camera. Among them, the front camera, or front shooter, can be a camera arranged on the front of the electronic device, and can be used for functions such as selfies, video calls, and face recognition.

[0077] The functional module is located at the top edge of the main board module 4, the shielding cover 41 is located below the functional module, and the connection component 42 is located on the horizontal side of the functional module.

[0078] The metal foil 2 is located on the back of the module body 1. The metal foil 2 includes a first ground return structure 211 and a second ground return structure 212. The first ground return structure 211 extends downward to connect to the shielding cover 41, and the second ground return structure 212 extends to the horizontal side to connect to the connection component 42.

[0079] In this embodiment, the main board module 4 is arranged at the upper part of the electronic device, the functional module (i.e., the front camera) is arranged at the top edge of the main board module 4, close to the top frame of the electronic device, and the antenna radiator 3 is located on the top frame. The bottom edge of the metal foil 2 is close to the shielding cover 41 of the main board module 4. Therefore, the first ground return structure 211 extends downward from the bottom edge of the metal foil 2 to connect to the shielding cover 41, realizing the first path of ground return. The left side of the metal foil 2 is closer to the connection component 42. Therefore, the second ground return structure 212 extends horizontally to the left from the left edge of the metal foil 2 to connect to the connection component 42, realizing the second path of ground return.

[0080] Both the first ground return structure 211 and the second ground return structure 212 are arranged at positions on the metal foil 2 that are relatively close to the ground return point, and both have short ground return paths, which can further reduce the influence of clutter.
