[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] In the description of the embodiments of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "thickness" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0027] It can be understood that in the conventional technical solutions, the GPS antenna in the L5 frequency band is arranged on the metal frame of the electronic device, or on the main board, circuit board, or bracket of the electronic device. The conventional GPS antenna structure in the L5 frequency band on the metal frame enables the GPS antenna in the L5 frequency band to obtain relatively good antenna efficiency, but it will occupy a relatively large antenna setting area, bringing an increase in the difficulty of the structural arrangement of other important communication antennas such as LTE and WIFI. Especially when the 5G antenna system is more and more applied to electronic devices, the area of the traditional frame of the electronic device available for setting the antenna radiator will become less and less. The conventional GPS antenna in the L5 frequency band is arranged on the main board, circuit board, or bracket, so that the performance of the antenna is limited by the size of the clearance area around the antenna. Since the operating frequency band of the L5 frequency band antenna is very low, compared with the L1 frequency band antenna, the L5 frequency band antenna requires a larger antenna clearance area. As electronic devices become thinner and lighter, the antenna clearance area of the L5 frequency band is restricted not to be too large. Therefore, the efficiency of arranging the radiator of the L5 frequency band antenna on the main board, circuit board, or bracket is often very low, usually not exceeding -15 dB. Therefore, in order to improve the electronic device to meet both the requirements of multi-antenna arrangement and the requirements of increasing the antenna clearance area, it is necessary to set the antenna radiator on the structure outside the frame, main board, circuit board, and bracket in the electronic device.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3, this application provides an electronic device 100, which includes a rear cover 10, a camera decorative part 20 embedded in the rear cover 10, and a first antenna module 30 fixed to the inner side of the rear cover 10. The first antenna module 30 is electrically connected to the camera decorative part 20 to feed power to the camera decorative part 20, so that the camera decorative part 20 radiates antenna signals.

[0029] It can be understood that the electronic device 100 can be a device such as a mobile phone, a laptop computer, or a tablet computer. The first antenna module 30 and the camera decorative part 20 form an antenna, and this antenna can be any one or a combination of a GPS antenna, a 5G antenna, a WIFI antenna, an NFC antenna, and a Bluetooth antenna.

[0030] By electrically connecting the camera decorative part 20 and the first antenna module 30, the camera decorative part 20 can receive the power feed from the first antenna module 30, so that the camera decorative part 20 can radiate antenna signals, making full use of the structural components of the electronic device 100, ensuring an increase in the clearance area of the antenna, and improving the antenna efficiency.

[0031] In this embodiment, the rear cover 10 serves as a protective structure on the back of the electronic device 100.

The bottom short side 12 can be adjacent to the power interface or the audio interface of the electronic device 100. The two long sides 13 can be respectively adjacent to the power button and the volume adjustment button of the electronic device 100.

[0033] The rear cover 10 has an outer surface 14 and an inner surface 15 opposite to the outer surface 14. The outer surface 14 forms the back of the electronic device 100 that can face the user. The space of the electronic device 100 adjacent to the inner surface 15 forms the inner space of the rear cover 10. The first antenna module 30 is fixed to the inner side of the rear cover 10, that is, the first antenna module 30 is fixed relative to the rear cover 10 and adjacent to the inner surface 15 of the rear cover 10.

[0034] Optionally, the rear cover 10 is a glass rear cover 10. Since the rear cover 10 is made of a non-metallic material, a relatively large clearance area can be provided for the camera decoration member 20, improving the antenna efficiency of the camera decoration member 20.

[0035] Optionally, the rear cover 10 is a ceramic rear cover 10. In addition to improving the antenna efficiency of the camera decoration member 20, the rear cover 10 can also increase the structural stability and ensure the safety of the electronic device 100.

[0036] Optionally, the rear cover 10 is a plastic rear cover 10. The rear cover 10 provides a relatively large antenna clearance area for the camera decoration member 20, and the rear cover 10 is easy to manufacture, reducing the production cost.

[0037] Optionally, the rear cover 10 is a metal rear cover 10, enhancing the back appearance performance of the electronic device 100 and improving the metallic texture of the appearance of the electronic device 100. The rear cover 10 is isolated from the camera decoration member 20 by an insulating material, and the insulating material forms the antenna clearance area of the camera decoration member 20 to ensure that the camera decoration member 20 can effectively radiate antenna signals.

[0038] In this embodiment, the camera decoration member 20 penetrates through the outer surface 14 and the inner surface 15 of the rear cover 10. The camera decoration member 20 is provided with a top that protrudes relative to the outer surface 14 or is flush with the outer surface 14. The top constitutes a structure for decorating the camera module on the back of the electronic device 100, so as to increase the position recognition of the camera module of the electronic device 100 and improve the back appearance performance of the electronic device 100. The camera decoration is also provided with a bottom that protrudes relative to the inner surface 15 or is flush with the inner surface 15. The bottom is electrically connected to the first antenna module 30. The camera decoration member 20 can cover, protect, and block light for the camera module of the electronic device 100 to ensure the performance of the electronic device 100 for effective photographing using the camera module. The camera decoration member 20 is embedded in the rear cover 10 and can function as an antenna radiator to generate resonance signals. The camera decoration member 20 can obtain a relatively large antenna clearance area, so that the antenna efficiency of the camera decoration member 20 is -9 dB to -10 dB, greatly improving the antenna efficiency.

[0039] Optionally, the camera decoration member 20 is embedded between the included angle of the short side 11 and the long side 13 of the top. For example, the camera decoration member 20 is embedded between the short side 11 of the top and the long side 13 adjacent to the power button.

[0040] Optionally, the camera decorative member 20 is adjacent to the top short side 11 and is located at a position between the two long sides 13.

[0041] Optionally, the camera decorative member 20 is a full-metal member, so as to increase the area where the camera decorative member 20 can radiate antenna signals.

[0042] Optionally, the camera decorative member 20 is an integrally formed structural member of a metal part and a non-metal part, so as to reduce the cost of the camera decorative member 20.

[0043] Specifically, the camera decorative member 20 is a decorative member of a multi-camera module. The camera decorative member 20 has a long decorative edge 21 parallel to the long side 13 and two short decorative edges 22 substantially parallel to the top short side 11. The two long decorative edges 21 and the two short decorative members together form the peripheral side of the camera decorative member 20, so that the outer shape of the camera decorative member 20 is generally in an oval track shape.

[0044] Optionally, the resonant frequency band of the camera decorative member 20 is a single frequency band, and the resonant frequency band of the camera decorative member 20 is 1.17 GHz ± 5 MHz, so that the first antenna module 30 and the camera decorative member 20 form a GPS antenna, and the camera decorative member 20 can meet the communication requirements of the L5 frequency band of the GPS antenna. Using the camera decorative member 20 as the radiator of the L5 frequency band GPS antenna enables the L5 frequency band GPS antenna of the electronic device 100 to obtain a larger antenna clearance area, improve the antenna efficiency, and the antenna efficiency can reach -9 dB to -10 dB.

[0045] Optionally, the resonant frequency band of the camera decorative member 20 is 1.575 GHz ± 5 MHz, so that the camera decorative member 20 can meet the communication requirements of the L1 frequency band of the GPS antenna.

[0046] Optionally, the resonant frequency band of the camera decorative member 20 is a multi-frequency band. The camera decorative member 20 can be divided into multiple radiators, and the electronic device 100 includes multiple first antenna modules 30, and the multiple first antenna modules 30 can be respectively electrically connected to the multiple radiators of the camera decorative member 20.

[0047] It can be understood that the first antenna module 20 is integrated on the antenna chip, and the antenna chip is used to electrically connect to the camera decorative member 20 to realize power feeding to the camera decorative member 20.

[0048] Furthermore, the electronic device 100 further includes a main board 40 fixed to the inner side of the rear cover 10, and the first antenna module 30 is disposed on the main board 40.

[0049] In this embodiment, the main board 40 is adjacent to the inner surface 15 of the rear cover 10. The main board 40 is provided with a processor and a conductive circuit electrically connected to the first antenna module 30. The processor is electrically connected to the first antenna module 30 via the conductive circuit to enable the processor to transmit and receive electrical signals with the first antenna module 30 via the conductive circuit, so that the first antenna module 30 can effectively communicate with the antenna formed by the camera decorative member 20. The main board 40 is also provided with functional devices such as a memory, a sensor, a radio frequency device, a circuit board connector, and various electronic components.

[0050] Optionally, the first antenna module 30 is disposed on the side of the main board 40 facing the rear cover 10, reducing the distance between the first antenna module 30 and the camera decorative member 20, which facilitates the electrical connection between the first antenna module 30 and the camera decorative member 20.

[0051] Optionally, the first antenna module 30 is disposed on the side of the main board 40 away from the rear cover 10. The main board 40 can be provided with a conductive member connecting the first antenna module 30. The conductive member extends from the side of the main board 40 away from the rear cover 10 to the side facing the rear cover 10 to facilitate the electrical connection of the camera decorative member 20 by using the conductive member. The first antenna module 30 is disposed on the side of the main board 40 away from the rear cover 10, making full use of the layout area of the main board 40 and optimizing the internal structure of the electronic device 100.

[0052] It can be understood that disposing the first antenna module 30 on the main board 40 enables the first antenna module 30 to be directly electrically connected to the processor of the main board 40 via a conductive circuit, which facilitates the effective transmission and reception of electrical signals between the first antenna module 30 and the processor. Disposing the first antenna module 30 on the main board 40 realizes the integration of the first antenna module 30 and the processor on the main board 40, which facilitates the manufacture of the first antenna module 30 and increases the compactness of the internal structure of the electronic device 100.

[0053] In another embodiment, as Figure 4 shown, and Figure 1The illustrated embodiments are substantially the same. The difference is that the electronic device 100 is provided with a camera telescopic structure 101, and the rear cover 10 and the camera decorative member 20 are disposed on the camera telescopic structure 101. The electronic device 100 further includes a circuit board 102 disposed on the camera telescopic structure 101, and the first antenna module 30 is disposed on the circuit board 102. The electronic device 100 is provided with a device body 103 that can move relative to the rear cover 10 and the camera decorative member 20, and the device body 103 is provided with a main board 40. The main board 40 is electrically connected to the circuit board 102 via a flexible circuit board. That is, both the camera decorative member 20 and the first antenna module 30 are telescopic relative to the main board 40, and the camera decorative member 20 and the first antenna module 30 are electrically connected to the main board 40 via the circuit board 102 and the flexible circuit board, so that the camera decorative member 20 can effectively radiate antenna signals.

[0054] Further, please refer to Figure 5 and Figure 6 , the electronic device 100 further includes a pressing plate bracket 50. The pressing plate bracket 50 presses and covers the main board 40 and is located between the rear cover 10 and the main board 40. The pressing plate bracket 50 is provided with a metal trace 60 electrically connected to the first antenna module 30, and the camera decorative member 20 is electrically connected to the metal trace 60.

[0055] In this embodiment, the pressing plate bracket 50 presses and covers each component on the main board 40, making each component on the main board 40 more stable. For example, the pressing plate bracket 50 can press and cover the board-to-board connector on the main board 40, and the pressing cover bracket can press and cover the plug-in components on the main board 40. The pressing plate bracket 50 can also cover each component on the main board 40 to protect each component on the main board 40. The pressing plate bracket 50 can also cover the first antenna module 30 to protect the first antenna module 30 and prevent the first antenna module 30 from being damaged. The pressing plate bracket 50 is a non-metallic part. The pressing plate bracket 50 provides an insulating environment for each component of the main board 40 and the first antenna module 30, ensuring the safety of each component on the main board 40 and the first antenna module 30.

[0056] Optionally, the pressing plate bracket 50 is made of plastic material, reducing the production cost of the pressing plate bracket 50.

[0057] Optionally, the pressing plate bracket 50 is a ceramic part to increase the rigidity of the pressing plate bracket 50, so that the pressing plate bracket 50 can effectively protect the main board 40 and increase the effective support of the pressing plate bracket 50 for the rear cover 10.

[0058] Optionally, the pressing plate bracket 50 is an integrally formed structural member of a metal part and a non-metal part, so as to facilitate electrically connecting the first antenna module 30 and the camera decorative member 20 by using the metal part of the pressing plate bracket 50.

[0059] In this embodiment, the metal trace 60 extends from the side of the pressing plate bracket 50 facing the main board 40 to the side facing the camera decorative member 20. The metal trace 60 can extend on the pressing plate bracket 50 according to a preset route, so that the metal trace 60 can avoid the position where the pressing plate bracket 50 presses the electronic devices on the main board 40, preventing the metal trace 60 from being short-circuited with the electronic devices on the main board 40. The function of the metal trace 60 is to be responsible for transmitting electrical signals between the first antenna module 30 and the camera decorative member 20, so that the antenna formed by the first antenna module 30 and the camera decorative member 20 can normally receive and transmit signals.

[0060] It can be understood that the metal trace 60 is a narrow strip-shaped metal conductive object. By arranging the metal trace 60 on the pressing plate bracket 50, it is ensured that most of the area of the pressing plate bracket 50 is a non-metal area, so that the pressing plate bracket 50 can provide an insulating environment and effectively stabilize the various devices on the main board 40. The metal trace 60 conducts electricity for the first antenna module 30 in a targeted manner, and uses the structure of the pressing plate bracket 50 to stack the main board 40, making full use of the layout space on the pressing plate bracket 50, so that the internal structure of the electronic device 100 is compact, and the conductive structure between the camera decorative member 20 and the first antenna module 30 is simplified. When assembling the electronic device 100, only need to press the pressing plate bracket 50 on the main board 40, and cover the camera decorative member 20 on the main board 40 along with the rear cover 10, then the camera decorative member 20 and the first antenna module 30 are conducted, which is fast and effective, and ensures the conduction performance between the camera decorative member 20 and the first antenna module 30.

[0061] Optionally, the metal trace 60 is arranged on the pressing plate bracket 50 by using laser direct structuring technology. The metal trace 60 extends along the surface of the pressing plate bracket 50 to ensure the scratch resistance of the metal trace 60 and ensure the effective conductive performance of the metal trace 60.

[0062] Optionally, the metal trace 60 is formed on the pressing plate bracket 50 by using a metal coating process, so that the metal trace 60 can be formed quickly and simply.

[0063] Optionally, the metal trace 60 is a copper foil circuit formed by screen printing process.

[0064] Optionally, the metal trace 60 is a columnar metal conductor passing through the pressing plate bracket 50.

[0065] Specifically, please refer to Figure 5 , Figure 7 and Figure 8 . The pressing plate bracket 50 is provided with through holes 51 with two open ends facing the main board 40 and the camera decorative member 20 respectively. The metal trace 60 passes through the inner wall of the through hole 51. The through hole 51 is generally opposite to the edge of the camera decorative member 20. The extending direction of the through hole 51 is generally perpendicular to the pressing plate bracket 50. The opening diameter of the through hole 51 facing the main board 40 is larger than the opening diameter facing the camera decorative member 20. The part of the metal trace 60 passing through the inner wall of the through hole 51 covers the peripheral side wall of the through hole 51. The metal trace 60 is further provided with a first connection end 61 extending out of the opening end of the through hole 51 facing the outside of the main board 40, and a second connection end 62 extending out of the opening end of the through hole 51 facing the outside of the decorative member. The first connection end 61 and the second connection end 62 extend along the bottom surface and the top surface of the pressing plate bracket 50 respectively. By using one end of the through hole 51 having a larger diameter than the other end, it is convenient for the covering area of the first connection end 61 to be larger than that of the second connection end 62, so as to facilitate the first connection end 61 to connect to the first antenna module 30 of the main board 40 and the second connection end 62 to connect to the edge of the camera decorative member 20.

[0066] Optionally, two through holes 51 are provided on the pressing plate bracket 50, and the metal traces 60 are arranged on the inner walls of the two through holes 51. The two through holes 51 are respectively opposite to two decorative long sides 13 of the camera decorative member 20, or respectively opposite to two decorative short sides.

[0067] Optionally, one through hole 51 is provided on the pressing plate bracket 50, and the one through hole 51 is opposite to one of the decorative long sides 13 of the camera decorative member 20, or opposite to one of the decorative short sides.

[0068] Optionally, more than two through holes 51 are provided on the pressing plate bracket 50, and the metal traces 60 are arranged on the inner walls of the more than two through holes 51. The more than two through holes 51 are arranged equidistantly along the periphery of the camera decorative member 20.

[0069] Furthermore, please refer to Figure 5 and Figure 9 . The electronic device 100 further includes a conductive elastic sheet 70 fixed to the main board 40. One end of the conductive elastic sheet 70 is electrically connected to the first antenna module 30, and the other end elastically abuts against the metal trace 60 of the pressing plate bracket 50.

[0070] In this embodiment, the conductive elastic sheet 70 is provided with a fixed end 71 and an elastic contact end 72 extending from the fixed end 71. The fixed end 71 is fixed to one end of the main board 40 facing the pressing plate bracket 50, and the elastic contact end 72 elastically contacts the first connection end 61 of the metal trace 60. The conductive elastic sheet 70 serves as the feed conduction device of the first antenna module 30. The conductive elastic sheet 70 is responsible for the electrical signal transmission between the first antenna module 30 and the metal trace 60, and facilitates the metal trace 60 to remain in a conductive state with the conductive elastic sheet 70 after the pressing plate bracket 50 is combined and covered on the main board 40, so as to facilitate the electrical connection between the first antenna module 30 and the camera decorative member 20. The fixed end 71 is constantly fixed to the main board 40 and is constantly in conduction with the feed signal output end of the first antenna module 30 on the main board 40, so that the first antenna module 30 and the conductive elastic sheet 70 are constantly connected. After the pressing plate bracket 50 and the main board 40 are pressed and covered, the elastic contact end 72 generates elastic deformation under the action of the pressing force of the pressing plate bracket 50, so that the elastic contact end 72 can stably contact the first connection end 61 of the metal trace 60 under the action of the elastic deformation force. By using the relatively large effective covering area of the first connection end 61, the elastic contact end 72 can effectively contact the first connection end 61 of the metal trace 60, avoiding the disconnection between the conductive elastic member and the metal trace 60.

[0071] Optionally, the fixed end 71 of the conductive elastic sheet 70 is welded to the first antenna module 30 on the main board 40, so that the first antenna module 30 and the conductive elastic sheet 70 are firmly connected.

[0072] Optionally, the fixed end 71 of the conductive elastic sheet 70 and the first antenna module 30 on the main board 40 can be inserted and conducted through a jack, so as to facilitate the disassembly and maintenance of the conductive elastic sheet 70.

[0073] Optionally, the fixed end 71 of the conductive elastic sheet 70 can also be bonded to the first antenna module 30 on the main board 40 through conductive adhesive, so as to facilitate the quick assembly and firmness of the conductive elastic sheet 70 and the main board 40.

[0074] Optionally, an anti-oxidation layer can be coated on the first connection end 61 to avoid oxidation of the first connection end 61 and ensure effective contact between the first connection end 61 and the conductive elastic sheet 70.

[0075] Optionally, a scratch-resistant coating can also be coated on the first connection end 61 to increase the scratch resistance of the first connection end 61 and avoid the elastic contact end 72 scratching the first connection end 61.

[0076] Further, the electronic device 100 further includes an elastic conductive member 80, which is elastically compressed between the pressing plate bracket 50 and the camera decorative member 20, and the camera decorative member 20 is electrically connected to the metal trace 60 through the elastic conductive member 80.

[0077] In this embodiment, the elastic conductive member 80 is assembled between the camera decorative member 20 and the pressing plate bracket 50. One side of the elastic conductive member 80 abuts against the bottom edge of the camera decorative member 20, and the other side abuts against the second connection end 62 of the metal trace 60. The elastic conductive member 80 serves as an electrical conductor between the metal trace 60 and the camera decorative member 20, and is responsible for the electrical signal transmission between the second connection end 62 of the metal trace 60 and the camera decorative member 20. The elastic conductive member 80 has electrical conductivity and can be elastically deformed and compressed under the pressing force, so that the elastic conductive member 80 can tightly abut against the metal trace 60 on the pressing plate bracket 50 and tightly abut against the camera decorative member 20.
