[0051] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0052] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance. The term "plurality" refers to two or more, unless otherwise expressly defined. Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by those of ordinary skill in the art. To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0053] In the related art, in electronic devices such as mobile terminals, as the functions of electronic devices increase, the number of antennas in the electronic devices also increases. Among the multiple antennas, some antennas are far away from the mainboard 30, which makes it difficult to connect the antennas to the mainboard 30.

[0054] The exemplary embodiments of the present disclosure provide an electronic device such as Figure 1 and Figure 2 As shown, the electronic device includes an antenna assembly 10, a mainboard 30, and an adapter assembly 20. There is a gap between the mainboard 30 and the antenna assembly 10, and a feed terminal is provided on the mainboard 30. The adapter assembly 20 is electrically connected to the antenna assembly 10 and the feed terminal on the mainboard 30. The adapter assembly 20 includes a first adapter 21 and a second adapter 22. The first adapter 21 is electrically connected to the feed terminal on the mainboard 30, the second adapter 22 is electrically connected to the antenna assembly 10, and the first adapter 21 and the second adapter 22 are electrically connected.

[0055] The electronic device provided by the embodiment of the present disclosure includes an antenna assembly 10, a mainboard 30 and an adapter assembly 20. There is a gap between the mainboard 30 and the antenna assembly 10. A feeding end is provided on the mainboard 30. The adapter assembly 20 includes a first adapter 21 and a second adapter 22. The first adapter 21 is electrically connected to the feeding end on the mainboard 30, and the second adapter 22 is electrically connected to the antenna assembly 10. The adapter assembly 20 is formed by the first adapter 21 and the second adapter 22 to connect the antenna assembly 10 and the feeding end on the mainboard 30, thereby solving the problem of difficulty in connecting the antenna assembly 10 and the mainboard 30 due to the large distance between the antenna assembly 10 and the mainboard 30, and improving the convenience of connecting the antenna assembly 10 and the mainboard 30.

[0056] The electronic devices provided by the embodiments of the present disclosure are described below using multiple embodiments:

[0057] The antenna assembly 10 is used to transmit and receive electromagnetic waves. In other words, the antenna assembly 10 can be understood as an antenna radiator. The antenna assembly 10 can convert the electrical signals sent by the RF module into electromagnetic waves, and can also convert the received electromagnetic waves into electrical signals. The antenna assembly 10 is provided with at least one feeding point and at least one grounding point. The feeding point is used to connect to the feeding terminal on the mainboard 30, and the grounding point is used to connect to the grounding member.

[0058] The antenna assembly 10 may be made of metal material, and may be a metal branch, a metal sheet, or a metal ring, etc. For example, the antenna assembly 10 may be a rectangular ring or a structure similar to a rectangular ring.

[0059] There is a gap between the mainboard 30 and the antenna assembly 10. The mainboard 30 is provided with a feed terminal, which is used to transmit excitation signals to the antenna assembly 10 and receive signals received by the antenna assembly 10. The mainboard 30 may be provided with an antenna matching circuit, one end of which forms the feed terminal.

[0060] The mainboard 30 may be provided with a radio frequency module, which is connected to the antenna assembly 10 via an antenna matching circuit. The radio frequency module is used to process, convert, and amplify baseband signals, and to demodulate and filter signals received by the antenna.

[0061] like Figure 5 As shown, the electronic device may include a middle frame, a display device, a back cover 60, and a motherboard 30. The display device is located on one side of the middle frame, forming the display surface of the electronic device, and the back cover 60 is located on the other side of the middle frame, forming the rear surface of the electronic device. The display device, middle frame, and back cover 60 enclose a housing space, and the motherboard 30 is located within this housing space.

[0062] In some embodiments, the antenna assembly 10 can be disposed on the back cover 60. For example, the antenna assembly 10 can be a metal component in a lens deco. This metal component surrounds the lens assembly of the electronic device and serves as an antenna radiator for the electronic device. In addition, the metal component is used to decorate the rear camera of the electronic device.

[0063] When the antenna assembly 10 is arranged on the back cover 60, the antenna assembly 10 at least partially protrudes from the surface of the back cover 60, which can increase the distance between the antenna assembly 10 and other antennas in the electronic device, thereby avoiding mutual influence between the antenna assembly 10 and other antennas and improving the performance of the antenna assembly 10.

[0064] It is understood that the antenna assembly 10 in the disclosed embodiment is not limited to being disposed on the back cover 60, and the antenna assembly 10 may also be disposed on the middle frame. For example, the middle frame is made of metal material and includes multiple metal segments, and the metal segments on the middle frame are the antenna assembly 10.

[0065] The antenna assembly 10 is provided with at least one feeding point and at least one grounding point, and the mainboard 30 is provided with a feeding terminal and a grounding terminal. The feeding point on the antenna assembly 10 is electrically connected to the feeding terminal on the mainboard 30 through the adapter assembly 20.

[0066] In some embodiments, the antenna assembly 10 is provided with a first feed point and a second feed point, each of which is connected to the second adapter 22. The antenna assembly 10 is connected to the second adapter 22 via two feed points, so that the antenna assembly 10 can still operate even if one feed point fails, thereby improving the stability of the connection between the antenna assembly 10 and the second adapter 22.

[0067] In order to achieve grounding of the antenna assembly, the electronic device in the embodiment of the present disclosure may further include at least one grounding member connected to a grounding point on the antenna assembly 10 and extending to a grounding terminal on the mainboard 30 .

[0068] In some embodiments, a first grounding point, a second grounding point, and a third grounding point are provided on the antenna assembly 10. Based on this, the electronic device includes a first grounding member 41, a second grounding member 42, and a third grounding member 43, wherein the first grounding member 41 is connected to the first grounding point, the second grounding member 42 is connected to the second grounding point, and the third grounding member 43 is connected to the third grounding point.

[0069] For example, the antenna assembly 10 has a rectangular or approximately rectangular ring structure and includes a first metal segment, a second metal segment, a third metal segment, and a fourth metal segment. The first metal segment, the second metal segment, the third metal segment, and the fourth metal segment are connected end to end, and the first metal segment, the second metal segment, the third metal segment, and the fourth metal segment each form a side of the rectangular antenna assembly 10. The first feeding point and the second feeding point can be provided on the first metal segment, the first grounding point can be provided on the second metal segment, the second grounding point can be provided on the third metal segment, and the third grounding point can be provided on the third metal segment.

[0070] Among them, the first grounding member 41 can be connected to the second metal segment by welding or bolting, the second grounding member 42 can be connected to the third metal segment by welding or bolting, and the third grounding member 43 can be connected to the fourth metal segment by welding or bolting.

[0071] The first adapter 21 includes an adapter post, one end of which is electrically connected to the feeding end on the mainboard 30, and the other end of which extends toward the direction close to the antenna assembly 10 and is electrically connected to the second adapter 22. The adapter post is perpendicular to the mainboard 30.

[0072] The adapter post is made of a metal material, such as a copper post, aluminum post, or steel post. It can have a cylindrical, quadrangular, or hexagonal structure. One end of the adapter post is welded to the feed port on the mainboard 30, and the other end is welded to the second adapter 22.

[0073] The diameter and height of the adapter post can be determined according to the distance between the mainboard 30 and the antenna assembly 10. For example, if the distance between the adapter and the antenna assembly 10 is 5.87 mm, the height of the adapter post can be 2.36 mm and the diameter of the adapter post is 1.9 mm.

[0074] In one possible implementation, Figure 3 As shown, the second adapter 22 may include a first elastic piece 221 and an adapter piece 222 . The first elastic piece 221 is electrically connected to the first adapter 21 ; the adapter piece 222 is electrically connected to the first elastic piece 221 and the antenna assembly 10 .

[0075] The thickness of the first spring piece 221 is smaller than that of the adapter piece 222. For example, the thickness of the first spring piece 221 is 0.35 mm, and the thickness of the adapter piece 222 is 2.05 mm. The stiffness of the first spring piece 221 is smaller than that of the adapter piece 222, and the stiffness of the first spring piece 221 is also smaller than that of the first adapter 21. In other words, the first spring piece 221 is more easily deformed than the first adapter 21 and the adapter piece 222. This effectively solves installation difficulties of the adapter assembly 20 caused by machining errors (e.g., inaccurate alignment or installation gaps).

[0076] like Figure 4 As shown, the adapter plate 222 may include a plate body 201, a first lug 202 and a second lug 203; the first lug 202 is provided at the first end of the plate body 201, and the first lug 202 is connected to the first elastic piece 221; the second lug 203 is provided at the second end of the plate body 201, and the second lug 203 is electrically connected to the antenna assembly 10.

[0077] The sheet 201 can be a rectangular or approximately rectangular sheet-like structure. The sheet 201 has a length, a width, and a thickness. The length of the sheet 201 is greater than the width, and the width is greater than the thickness. The first end and the second end of the sheet 201 are respectively located at the two ends of the sheet 201 along the length direction. That is, the first lug 202 and the second lug 203 are respectively located at the two ends of the sheet 201 along the length direction. The first lug 202 and the second lug 203 are also located at the two ends of the sheet 201 along the width direction. For example, the first lug 202 is located at the lower left corner of the sheet 201, and the second lug 203 is located at the upper right corner of the sheet 201.

[0078] The first and second lugs 202, 203 can be formed by bending the lugs on the sheet 201. The first and second lugs 202, 203 are respectively arranged perpendicular to the sheet 201. During installation, the width of the sheet 201 is perpendicular to the mainboard 30. The width of the sheet 201 is greater than its thickness. Therefore, by aligning the width of the sheet 201 with the mainboard 30, the space occupied by the sheet 201 in a direction parallel to the mainboard 30 can be reduced. Given the limited space within the lens trim of electronic devices, the arrangement of the sheet 201 effectively enables electrical connection perpendicular to the mainboard 30 and prevents the adapter 222 from occupying excessive space parallel to the mainboard 30.

[0079] In another feasible embodiment, the second adapter 22 may include a first spring clip 221, an adapter plate 222 and a second spring clip 223, wherein the first spring clip 221 is electrically connected to the first adapter 21; the adapter plate 222 is electrically connected to the first spring clip 221 and the antenna assembly 10, and the second spring clip 223 is electrically connected to the adapter plate 222 and the antenna assembly 10 respectively.

[0080] The thickness of the second spring piece 223 is smaller than that of the adapter plate 222, resulting in a smaller stiffness of the second spring piece 223 than that of the adapter plate 222. Furthermore, the stiffness of the second spring piece 223 is smaller than that of the first adapter 21. In other words, the second spring piece 223 is more easily deformed than the first adapter 21 and the adapter plate 222, effectively resolving difficulties in installing the adapter assembly 20 due to manufacturing errors and other factors (e.g., inaccurate alignment or installation gaps).

[0081] The adapter plate 222 is connected to the first feeding point of the antenna assembly 10, and the second spring piece 223 is connected to the second feeding point of the antenna assembly 10, realizing the dual connection between the adapter assembly 20 and the adapter assembly 20, and improving the stability of the electrical connection of the antenna assembly 10.

[0082] On this basis, the adapter plate 222 may include a plate body 201, a first lug 202, a second lug 203, and a third lug 204. The first lug 202 is provided at a first end of the plate body 201 and is connected to the first elastic piece 221. The second lug 203 is provided at a second end of the plate body 201 and is electrically connected to the antenna assembly 10. The third lug 204 is electrically connected to the second elastic piece 223 and is located between the first lug 202 and the second lug 203.

[0083] The sheet 201 can be a rectangular or approximately rectangular sheet-like structure. The sheet 201 has a length, a width, and a thickness. The length of the sheet 201 is greater than the width, and the width is greater than the thickness. The first end and the second end of the sheet 201 are respectively located at the two ends of the sheet 201 along the length direction. That is, the first lug 202 and the second lug 203 are respectively located at the two ends of the sheet 201 along the length direction. The first lug 202 and the second lug 203 are respectively located at the two ends of the sheet 201 along the width direction. For example, the first lug 202 is located at the lower left corner of the sheet 201, the second lug 203 is located at the upper right corner of the sheet 201, and the third lug 204 is located in the upper middle area of ​​the sheet 201.

[0084] The first lug 202, the second lug 203, and the third lug 204 can be formed by bending the lugs on the sheet 201. The first lug 202, the second lug 203, and the third lug 204 are respectively arranged perpendicular to the sheet 201. During installation, the width of the sheet 201 is perpendicular to the mainboard 30. The width of the sheet 201 is greater than the thickness of the sheet 201. Therefore, by making the width of the sheet 201 perpendicular to the mainboard 30, the space occupied by the sheet 201 in the direction parallel to the mainboard 30 can be reduced. In electronic devices, the space within the lens decorative component is limited. The arrangement of the sheet 201 effectively achieves electrical connection perpendicular to the mainboard 30 and prevents the adapter 222 from occupying excessive space parallel to the mainboard 30.

[0085] For example, when the antenna assembly 10 has a rectangular or approximately rectangular frame structure, the first and second feed points are located on the first metal segment. The first metal segment may be provided with an inwardly protruding connection lug, with the first feed point located on the main structure of the first metal segment and the second feed point located at the connection lug on the first metal segment. The second lug 203 is bolted to the first feed point, and the third lug 204 is welded to the connection lug on the first metal segment.

[0086] In some embodiments, the grounding member is used to connect to the feed terminal on the mainboard 30 and to reinforce the antenna assembly 10. The grounding member may include a grounding portion and a reinforcement portion. The grounding portion is connected to a grounding point on the antenna assembly 10, and the reinforcement portion is connected to the grounding portion. The reinforcement portion is connected to the back of the antenna assembly 10 to reinforce the antenna assembly 10.

[0087] In some embodiments, the electronic device may further include a suspension member 50 disposed on the antenna assembly 10. The suspension member 50 is made of a conductive material (e.g., a steel sheet) and is insulated from the antenna assembly 10. For example, an insulating layer may be provided between the antenna assembly 10 and the suspension member 50. The suspension member 50 can effectively improve the gain of the antenna assembly 10.

[0088] When the antenna assembly 10 is rectangular or approximately rectangular, the suspension member 50 is disposed on the second metal segment and is located on the side of the first grounding member 41 that is closer to the first metal segment. The suspension member 50 can also further enhance the strength of the antenna assembly 10 as a lens decoration.

[0089] In order to improve the isolation of the antenna assembly 10, an antenna matching circuit is provided on the mainboard 30, such as Figure 6 As shown, the antenna matching circuit includes a matching inductor L, a first capacitor C1, and a second capacitor C2. The first end of the matching inductor L is connected to the RF circuit, and the second end of the matching inductor L is connected to the feed terminal. The first end of the first capacitor C1 is connected to the first end of the matching inductor L, and the second end of the first capacitor C1 is connected to a reference power supply terminal (e.g., ground). The first end of the second capacitor C2 is connected to the second end of the matching inductor L, and the second end of the second capacitor C2 is connected to the reference power supply terminal. The parallel connection of the first capacitor C1 and the second capacitor C2 can effectively improve the isolation between the antenna assembly 10 and other antennas in the electronic device.

[0090] The mainboard 30 may be provided with a connector 31 (Cable connector), the antenna matching circuit is connected to the connector 31, and the connector 31 is connected to the RF module. Connecting the antenna matching circuit and the RF circuit via the connector 31 can improve the convenience of connection and facilitate disassembly and maintenance.

[0091] For example, the operating frequency band of the antenna assembly 10 is the L5 band. For example, the center frequency of the L5 band is 1176.45 MHz, and the frequency range corresponding to the L5 band can be 1176.45±1.023 MHz, that is, 1175.427 MHz to approximately 1177.473 MHz. The antenna assembly 10 can be used as a GPS L5 band antenna.

[0092] In some embodiments, the antenna assembly 10 is also used to form a lens trim for an electronic device. For example, the lens trim includes a metal ring that forms the antenna assembly 10. In this case, the antenna assembly 10 is located on the back cover 60 of the electronic device and surrounds the camera assembly 70 on the back cover 60. In addition to the antenna formed by the lens trim, other antennas may also be provided in the electronic device. For example, multiple metal segments may be provided on the frame of the electronic device, and these metal segments may serve as antennas.

[0093] For example, the antenna assembly 10 formed by the lens trim is the first antenna radiator, and multiple second antenna radiators are also formed on the frame of the electronic device. One of the multiple second antenna radiators is an antenna radiator for the GPS L1 band. This enables wireless communication between the electronic device's L1 and L5 bands, improving the communication performance of the electronic device's GPS. The multiple second antenna radiators can also include WiFi 2.4 antennas, WiFi 5G antennas, MHB antennas, N78 antennas, etc.

[0094] When the antenna assembly 10 provided by the embodiment of the present disclosure is used as an antenna in the GPS L5 frequency band, the current in the antenna assembly 10 is as follows: Figure 7 When the antenna assembly 10 is fed, a LOOP mode is excited, and a unidirectional current is generated in the y direction in this mode of the antenna assembly, thereby ensuring good radiation performance of the antenna assembly 10.

[0095] Figure 8 is the S parameter curve of the antenna assembly 10 when it works in the GPS L5 frequency band, Figure 8 The antenna assembly 10 can be seen to resonate at 1.176 GHz, which is the operating frequency of GPS L5. Figure 9 : is the efficiency curve of the antenna assembly 10, and its radiation efficiency is -7dB, achieving excellent performance. Figure 10 The isolation between the antenna assembly 10 and the WiFi2.4 antenna, WiFi5G antenna, MHB antenna, and N78 antenna on the frame of the electronic device is higher than 25dB, achieving good antenna isolation.

[0096] The electronic device provided in the embodiments of the present disclosure can be a mobile phone, tablet computer, e-reader, MP3 player, MP4 player, laptop computer, car computer or desktop computer, portable terminal, laptop terminal, desktop terminal, sports camera, drone, monitor camera and other similar products.

[0097] like Figure 11 As shown, the electronic device may also include one or more of the following components: a processing component 802 , a memory 804 , a power component 806 , a multimedia component 808 , an audio component 810 , an input / output (I / O) interface 812 , a sensor component 814 , and a communication component 816 .

[0098] The processing component 802 generally controls the overall operation of the electronic device, such as operations associated with display, phone calls, data communications, camera operation, and recording operations. The processing component 802 may include one or more processors 820 to execute instructions to perform all or part of the steps of the above-described method. In addition, the processing component 802 may include one or more modules to facilitate interaction between the processing component 802 and other components.
