[0021] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0022] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in a "or" relationship.

[0023] With the rapid development of information technology, the use of near field communication (NFC) is more and more, and the performance requirements of consumers for mobile phone NFC are also higher. Under the premise of smaller and smaller internal space of mobile phone, the design scheme of NFC structure needs to be more extreme, so that more mobile phones can have NFC function, which is convenient for people's life, so as to promote the development of NFC in more mobile terminal industry.

[0024] In the related art, the NFC antenna on the electronic device such as mobile phone is arranged on the metal frame. However, with the development of communication technology, the metal frame of the electronic device is usually used to deploy more important antennas, such as cellular antennas, etc., resulting in that the FPC constituting the radiator of the NFC antenna can only be placed on the back of the electronic device, such as shown in Figure 1a The NFC antenna 101 is arranged on the first mainboard support 102, so that the arrangement on the first mainboard support 102 increases the stack in the thickness direction of the electronic device, which is not conducive to the light and thin development trend of the electronic device. Or as shown in Figure 1b The NFC antenna 101 is placed in the battery area, and at this time, the NFC antenna 101 needs to be partially extended to the area where the first mainboard support 102 is located, so as to be fixedly connected with the first mainboard support 102 by adhesive fixing. At this time, the first mainboard spring piece 103 needs to be arranged at the middle position of the first mainboard 104, resulting in that the utilization rate of the board area of the first mainboard 104 is low, so that a larger size of the first mainboard 104 is needed. This method also has the problem of causing the whole size of the electronic device to be large.

[0025] In this embodiment, the circuit board assembly and the battery are arranged side by side in the electronic device, while the antenna assembly is arranged opposite to the battery. For example, the antenna assembly and the battery are stacked. In this way, the circuit board assembly and the antenna assembly are arranged side by side. By providing an electrical connection part on the edge of the radiating body, the circuit board assembly can be electrically connected to the circuit board assembly through the electrical connection part. In addition, the shielding component is stacked with the radiating body, and a flexible connector is provided on the side of the shielding component near the circuit board assembly. In this way, the antenna assembly can be fixed to one side of the circuit board assembly through the flexible connector, so that the NFC antenna assembly and the circuit board assembly do not overlap in the thickness direction of the electronic device, which helps to reduce the overall size of the electronic device.

[0026] It is worth mentioning that the radiating body in the embodiments of this application can be any antenna radiating body composed of FPC. In the embodiments of this application, an NFC antenna is usually used as an example for illustration. However, in other embodiments of this application, the radiating body can also be any antenna composed of FPC, such as a WiFi antenna or a Global Positioning System (GPS) antenna.

[0027] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0028] See Figure 2 , Figure 3 , Figure 4a and Figure 4b The electronic device provided in this application embodiment includes: an antenna assembly 100, a circuit board assembly 200, and a battery 300;

[0029] The circuit board assembly 200 and the battery 300 are arranged side by side, the antenna assembly 100 is arranged opposite to the battery 300, and the antenna assembly 100 is fixedly connected to the edge of the circuit board assembly 200 near the battery 300.

[0030] The antenna assembly 100 includes a radiating body 10 and a shielding member 23 stacked together. The shielding member 23 is located between the radiating body 10 and the battery 300. An electrical connection part 11 is provided on the side of the radiating body 10 near the circuit board assembly 200. The antenna assembly 100 is electrically connected to the circuit board assembly 200 through the electrical connection part 11. A flexible connector 24 is provided on the side of the shielding member 23 near the circuit board assembly 200. The antenna assembly 100 is fixedly connected to the circuit board assembly 200 through the flexible connector 24.

[0031] In some embodiments, the electronic device provided by the embodiments of the present application can be a terminal or other device than a terminal. For example, the electronic device can be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted electronic device, a Mobile Internet Device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc. The electronic device can also be a server, a Network Attached Storage (NAS), a personal computer (PC), a television (TV), a teller machine, or a self-service machine, etc. The embodiments of the present application are not limited in this regard.

[0032] For ease of illustration, the embodiments of the present application are generally exemplified by taking a mobile phone as an example of the electronic device, which does not constitute a specific limitation.

[0033] In some embodiments, the circuit board assembly 200 and the battery 300 are arranged side by side, which can be arranged side by side along the length or width direction of the electronic device. For example, as shown in FIG. 2, the circuit board assembly 200 is arranged above the battery 300 along the length direction of the electronic device. Figure 2

[0034] In some embodiments, the antenna assembly 100 is arranged opposite to the battery 300, which can be arranged in a stack along the thickness direction of the electronic device. For example, as shown in FIG. 3, the antenna assembly 100 covers one side of the battery 300 facing the back cover of the electronic device. Figure 2

[0035] In some embodiments, the antenna assembly 100 is fixedly connected to the side edge of the circuit board assembly 200 close to the battery 300, which can be achieved by the shielding member 23 and the flexible connecting member 24. Specifically, the shielding member 23 is stacked with and fixed to the radiation body 10, for example, the shielding member 23 is stacked with and fixed to the radiation body 10 by gluing or clamping, etc. The flexible connecting member 24 is arranged on the side of the shielding member 23 close to the circuit board assembly 200 and is fixedly connected to the circuit board assembly 200. In this way, the antenna assembly 100 can be fixedly connected to the side edge of the circuit board assembly 200 close to the battery 300.

[0036] ​​In some embodiments, the antenna assembly 100 is electrically connected with the circuit board assembly 200 through the electrical connection part 11, which can be understood as that the electrical connection part 11 is located at the side of the radiation main body 10 close to the circuit board assembly 200, so as to extend to the edge area of the circuit board assembly 200 to contact with the spring, contact or other electrical connection structure arranged at the edge of the circuit board assembly 200, so as to realize the electrical connection between the antenna assembly 100 and the circuit board assembly 200.

[0037] In some embodiments, the electrical connection structure on the main board 201 electrically connected with the electrical connection part 11 can include any electrical connection structure such as a spring, a contact or the like. For the convenience of description, as shown in Figure 8 and Figure 9 , in the embodiments of the present application, the electrical connection structure is taken as the spring 2011 on the main board 201 as an example for illustration, which does not constitute a specific limitation.

[0038] In some embodiments, the circuit board assembly 200 includes a main board support 202 and a main board 201 fixed on one side surface of the main board support 202.

[0039] The edge area of the main board 201 is provided with a spring 2011, and the electrical connection part 11 is electrically connected with the spring 2011.

[0040] Among them, the main board 201 can be deployed with the feed of the antenna assembly 100, antenna matching, antenna switch and other radio frequency devices.

[0041] In some embodiments, the antenna assembly 100 is fixed on one side of the circuit board assembly 200 through the flexible connecting piece 24. Taking the antenna assembly 100 as an example, the NFC antenna assembly can be relatively fixed with the edge of the circuit board assembly 200, that is, the NFC antenna assembly is fixed on the edge of the circuit board assembly 200. In this way, the main board spring 2011 in the circuit board assembly 200 for electrical connection with the electrical connection part 11 can be arranged at the edge of the main board 201, which improves the utilization rate of the layout area of the main board 201, so that the main board function can be realized by using a smaller area of the main board 201, and the overall size of the electronic device can be reduced.

[0042] Compared with the related art, when the NFC antenna 101 is adhered with the first main board support 102, the NFC antenna 101 is partially stacked with the first main board support 102, and the first main board spring 103 needs to be arranged at the middle position of the first main board 104. In the embodiments of the present application, the radiation main body 10 and the main board support 202 are not stacked, which can reduce the stacking of the electronic device in the thickness direction, and the spring 2011 can be arranged at the edge of the main board 201, which can improve the utilization rate of the layout area of the main board 201, so that the main board function can be realized by using a smaller area of the main board 201, and the overall size of the electronic device can be reduced.

[0043] In some embodiments, the shielding member 23 can be nanocrystalline or other material capable of shielding electromagnetic radiation. For ease of illustration, the shielding member 23 is taken as an example of nanocrystalline in the embodiments of the present application.

[0044] In the present embodiment, based on the characteristic that the shielding member 23 can isolate electromagnetic waves, the shielding member 23 is arranged between the radiation body 10 and the battery 300, so that the shielding member 23 can separate the radiation body 10 from the battery 300, and the influence of the electromagnetic waves generated by the radiation body 10 on the battery 300 can be reduced.

[0045] In some embodiments, the flexible connecting member can be a material with flexibility and insulation, such as a polyethylene terephthalate (PET) film, a nylon insulating film, etc., which is not specifically limited herein.

[0046] It is worth mentioning that since nanocrystalline is a wafer made of hardware powder by a binder, it is easy to break when vibrating or bending. If the shielding member 23 is used to connect the radiation body 10 and the circuit board assembly 200, when the shielding member 23 breaks, the electrical connection part 12 will also be easy to break under the action of external force. In some embodiments of the present application, the shielding member 23 is arranged in a stack with the radiation body 10, and the flexible connecting member 24 is used to fix the antenna assembly 100 to the edge of the circuit board assembly 200, so that the connection reliability between the antenna assembly 100 and the circuit board assembly 200 can be improved.

[0047] In some embodiments, as shown in Figure 4b The antenna assembly 100 further includes a heat dissipation member 25, which is arranged on the side of the shielding member 23 facing the battery 300, and the side of the heat dissipation member 25 close to the circuit board assembly 200 is fixedly connected with the circuit board assembly 200.

[0048] In some embodiments, the heat dissipation member 25 can include a pyrolytic graphite sheet (PGS) or other structure capable of absorbing heat on one side of the circuit board assembly 200 and dissipating heat in other areas except the circuit board assembly 200, such as the battery area, which is not specifically limited herein.

[0049] In some embodiments, the heat dissipation member 25 is arranged on the side of the shielding member 23 facing the battery 300, and the heat dissipation member 25 can be fixed on the surface of the side of the shielding member 23 facing the battery 300 by any means such as adhesion, clamping, etc. At this time, the flexible connecting member 24 can be clamped between the heat dissipation member 25 and the shielding member 23, for example, as shown in Figure 4a and Figure 4bAs shown, the upper surface of the flexible connecting piece 24 is fixedly glued to the shielding piece 23, the lower surface of the flexible connecting piece 24 is fixedly glued to the heat dissipation piece 25, and the area of the heat dissipation piece 25 not opposite to the flexible connecting piece 24 is fixedly glued to the lower surface of the shielding piece 23.

[0050] In this way, the upper and lower surfaces of the flexible connecting piece 24 are fixedly connected to other structures in the antenna assembly 100, which can improve the connection firmness of the flexible connecting piece 24 and other structures in the antenna assembly 100.

[0051] Of course, in another embodiment, the heat dissipation piece 25 is arranged on the side of the shielding piece 23 facing the battery 300, which can be fixed on the surface of the side of the shielding piece 23 facing the battery 300 by any means such as gluing, clamping, etc., and the flexible connecting piece 24 can be fixed on the surface of the side of the heat dissipation piece 25 away from the shielding piece 23, which is not specifically limited here.

[0052] In this embodiment, the heat dissipation piece 25 can also be reused to strengthen the connection between the second main body part 21 and the main board support 202.

[0053] Of course, in some embodiments, the flexible connecting piece is part of the shielding piece 23, for example: Figure 10 As shown, the shielding piece 23 is used to form the flexible connecting piece, and at this time, the material of the flexible connecting piece can be nanocrystals.

[0054] In another embodiment, the flexible connecting piece 24 and the shielding piece 23 are made of different materials, for example: Figure 11 As shown, the material of the shielding piece 23 includes nanocrystals, which are only used to isolate electromagnetic radiation on the radiation main body 10, and are not used to connect the radiation main body 10 and the circuit board assembly 200; the material of the flexible connecting piece 24 can include a PET film, which is used to realize high-reliability connection between the radiation main body 10 and the circuit board assembly 200.

[0055] In this embodiment, based on the characteristic that the flexible connecting piece 24 has high toughness, compared with the way of using nanocrystals to fixedly connect the radiation main body 10 and the circuit board assembly 200, the connection reliability between the radiation main body 10 and the circuit board assembly 200 can be improved, and the service life of the electrical connecting part 11 can be improved, in addition, the replacement of part of the nanocrystals by the flexible connecting piece 24 can reduce the amount of nanocrystals used, thereby reducing the cost of the electronic device.

[0056] As shown in Figure 4a and Figure 4b As shown, the radiation main body 10, the shielding piece 23, the flexible connecting piece 24, and the heat dissipation piece 25 are arranged in sequence.

[0057] In some embodiments, the flexible connecting member 24 includes a first main body portion 241 and a first protruding portion 242, the first main body portion 241 being adhered to a side of the shielding member 23 facing away from the main body 10, and the first protruding portion 242 being fixedly connected to the circuit board assembly 200.

[0058] In some embodiments, the heat dissipation member 25 includes a second main body portion 251 and a second protruding portion 252, the second main body portion 251 being adhered to a side of the flexible connecting member 24 facing away from the shielding member 23, and the second protruding portion 252 being fixedly connected to the circuit board assembly 200.

[0059] In some embodiments, the first protruding portion 242 is fixedly connected to the circuit board assembly 200. In this case, the first protruding portion 242 with high toughness can improve the connection reliability between the antenna assembly 100 and the circuit board assembly 200.

[0060] In other embodiments, the second protruding portion 252 is fixedly connected to the circuit board assembly 200. In this case, the heat dissipation member 25 for dissipating heat from the main board 201 in the electronic device can be reused to achieve the connection between the antenna assembly 100 and the circuit board assembly 200, and the structure of the electronic device can be simplified.

[0061] In yet other embodiments, the first protruding portion 242 and the second protruding portion 252 are fixedly connected to the circuit board assembly 200, respectively.

[0062] For example, as shown in FIGS. 1 and 2, the shielding member 23, the first main body portion 241 of the flexible connecting member 24, and the second main body portion 251 of the heat dissipation member 25 are sequentially stacked. Figure 4a And Figure 4b The side of the first main body portion 241 close to the circuit board assembly 200 extends the first protruding portion 242, and the side of the second main body portion 251 close to the circuit board assembly 200 extends the second protruding portion 252, so as to be fixedly connected to the main board support 202 in the circuit board assembly 200 by the first protruding portion 242 and the second protruding portion 252.

[0063] In some embodiments, in the case where the flexible connecting member 24 includes the first protruding portion 242 and the heat dissipation member 25 includes the second protruding portion 252, the second protruding portion 252 is stacked with the first protruding portion 242.

[0064] In this way, when the first protrusion 242 and the second protrusion 252 are provided simultaneously, by stacking the second protrusion 252 and the first protrusion 242, the stacked second protrusion 252 and the first protrusion 242 form an integral protrusion, reducing the space occupied by the second protrusion 252 and the first protrusion 242, and also reducing the space occupied by the connecting parts on the motherboard bracket 202 that are respectively used to connect with the first protrusion 242 and the second protrusion 252.

[0065] For ease of explanation, in the following embodiments, the second protrusion 252 and the first protrusion 242 are stacked together to form a connector between the antenna assembly 100 and the circuit board assembly 200.

[0066] In some embodiments, the number of first protrusions 242 is at least two, and the at least two first protrusions 242 are spaced apart on opposite sides of the electrical connection portion 11;

[0067] And / or, the number of second protrusions 252 is at least two, and at least two second protrusions 252 are spaced apart on opposite sides of the electrical connection portion 11.

[0068] For example: Figure 4a , Figure 4b , Figure 5 and Figure 7 As shown, there are two first protrusions 242 and two second protrusions 252, and the two first protrusions 242 and the two second protrusions 252 are stacked in a one-to-one correspondence, so that the two first protrusions 242 are distributed at intervals on opposite sides of the electrical connection portion 11, and the two second protrusions 252 are distributed at intervals on opposite sides of the electrical connection portion 12.

[0069] Of course, the number of the first protrusion 242 or the second protrusion 252 may be greater than two, and no specific limitation is made here.

[0070] In this embodiment, at least one of a first protrusion 242 and a second protrusion 252 can be provided on opposite sides of the electrical connection portion 11, so that there are at least two fixed connection points between the antenna assembly 100 and the circuit board assembly 200, so that the antenna structure and the motherboard bracket 202 can be fixed at opposite sides of the electrical connection portion 11. Compared with the method of fixing the antenna assembly 100 and the circuit board assembly 200 only at one side of the electrical connection portion 11, this can improve the connection stability between the antenna assembly 100 and the circuit board assembly 200, and improve the relative stability between the electrical connection portion 11 and the circuit board assembly 200, thereby improving the electrical connection stability between the spring 2011 on the electrical connection portion 11 and the circuit board assembly 200.

[0071] In some embodiments, as shown in Figure 4a , Figure 4b , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the electric connection part 11 is provided with a first through hole 111, and the mainboard support 202 is provided with a first limiting piece 2021, and the first limiting piece 2021 is arranged through the first through hole 111.

[0072] In this embodiment, the first limiting piece 2021 can be a anti-falling positioning column on the mainboard support 202. By arranging the first limiting piece 2021 through the first through hole 111, the electric connection part 11 can be firmly hung on the first limiting piece 2021 when the electronic device receives external force, preventing the problem of disconnection between the electric connection part 11 and the spring piece 2011 caused by displacement of the electric connection part 11 due to external force, and improving the electrical connection reliability between the radiation main body 10 and the mainboard 201.

[0073] In some embodiments, as shown in Figure 4a , Figure 4b , Figure 5 , Figure 6 , Figure 7 and Figure 8 , in the case that the flexible connection piece 24 includes a first protruding part 242, the first protruding part 242 is provided with a second through hole 2421, and / or in the case that the heat dissipation piece 25 includes a second protruding part 252, the second protruding part 252 is provided with a third through hole 2521.

[0074] The mainboard support 202 is provided with a second limiting piece 2022, and the second limiting piece 2022 is arranged through the second through hole 2421 and / or the third through hole 2521.

[0075] In some embodiments, the second limiting piece 2022 can be a anti-falling positioning column on the mainboard support 202. By arranging the second limiting piece 2022 through the second through hole 2421 and / or the third through hole 2521, the flexible connection piece 24 and / or the heat dissipation piece 25 can be firmly hung on the second limiting piece 2022 when the electronic device receives external force, preventing the problem of the flexible connection piece 24 and / or the heat dissipation piece 25 being separated from the mainboard support 202 caused by the electronic device being subjected to external force, and improving the connection reliability between the flexible connection piece 24 and / or the heat dissipation piece 25 and the mainboard support 202.

[0076] In some embodiments, the electrical connection part 11 and the connecting part between the antenna assembly 100 and the circuit board assembly 200 are staggered along the first direction Z, wherein the first direction Z is the thickness direction of the electronic device, and the connecting part between the antenna assembly 100 and the circuit board assembly 200 can include at least one of the first protruding part 242 and the second protruding part 252.

[0077] In some embodiments, by staggering the electrical connection part 11 and the connecting part between the antenna assembly 100 and the circuit board assembly 200 along the first direction Z, the electrical connection part 11 and the connecting part between the antenna assembly 100 and the circuit board assembly 200 can respectively contact the opposite surfaces of the main board support 202, and thus be fixed on the opposite surfaces of the main board support 202.

[0078] For example, the main board 201 is fixed on one side of the main board support 202, at this time, the electrical connection part 11 can extend to the side of the main board support 202 facing the main board 201, and at least one of the first protruding part 242 and the second protruding part 252 can extend to the side of the main board support 202 away from the main board 201.

[0079] In some embodiments, the electrical connection part 11 and the connecting part between the antenna assembly 100 and the circuit board assembly 200 are staggered along the first direction Z, which can be that the free end of the electrical connection part 11 is bent towards the surface of one side of the main board support 202 to contact the surface of one side of the main board support 202, and the free end of at least one of the first protruding part 242 and the second protruding part 252 is bent towards the surface of the other side of the main board support 202 to contact the surface of the other side of the main board support 202.

[0080] In this embodiment, the surface of the side of the main board support 202 facing the main board 201 can have more areas to contact the electrical connection part 11 to press the electrical connection part 11 on the spring sheet 2011 on the main board 201, and the surface of the side of the main board support 202 away from the main board 201 can have more areas to be fixedly connected with at least one of the first protruding part 242 and the second protruding part 252, which can increase the fixed area of at least one of the first protruding part 242 and the second protruding part 252 with the main board support 202, thereby improving the connection reliability between the antenna assembly 100 and the circuit board assembly 200.

[0081] For example, the electric connecting part 11 is fixedly adhered to the first connecting part 2023 on the first surface 20A of the mainboard support 202, and the second protruding part 252 is fixedly adhered to the second connecting part 2024 on the second surface 20B of the mainboard support 202. In this way, the electric connecting part 11 and the second protruding part 252 are adhered to the opposite surfaces of the mainboard support 202, which can increase the area of the connecting part on the mainboard support 202 for adhering the electric connecting part 11 and the second protruding part 252, and further increase the adhesion strength between the electric connecting part 11 and the first connecting part 2023, and the adhesion strength between the second protruding part 252 and the second connecting part 2024.

[0082] In some embodiments, on the basis of the fixed connection of the electric connecting part 11 and the first connecting part 2023, and the fixed connection of the second protruding part 252 and the second connecting part 2024 by adhesive fixing, the connection reliability between the antenna assembly 100 and the circuit board assembly 200 can be further enhanced by combining the above-mentioned way of penetrating the through holes on the electric connecting part 11, the first protruding part 242 and the second protruding part 252 with the anti-disengagement positioning columns on the mainboard support 202.

[0083] As an optional embodiment, as shown in Figure 7 and Figure 8 The first limiting part 2021 is located on the first surface 20A of the mainboard support 202, and the second limiting part 2022 is located on the second surface 20B of the mainboard support 202. The first surface 20A is the surface of the mainboard support 202 facing the mainboard 201, and the second surface 20B is the surface of the mainboard support 202 facing away from the mainboard 201.

[0084] In some embodiments, the first limiting part 2021 can be specifically arranged at the first connecting part 2023 of the mainboard support 202, and the second limiting part 2022 can be specifically arranged at the second connecting part 2024 of the mainboard support 202.

[0085] In some embodiments, as shown in Figure 2 The antenna assembly 100 is at least partially stacked with the battery 300 of the electronic device. By clamping the shielding part 23 between the radiation main body 10 and the battery 300, the influence of the electromagnetic radiation of the radiation main body 10 on the battery 300 can be reduced by using the radiation isolation function of the shielding part 23.

[0086] In the embodiment of the present application, the electronic device comprises a circuit board assembly, a battery and an antenna assembly; the circuit board assembly and the battery are arranged side by side, the antenna assembly is arranged opposite to the battery, and the antenna assembly is fixedly connected to the side edge of the circuit board assembly close to the battery; by arranging the electrically connecting part on the edge of the radiation main body, when the antenna assembly and the circuit board assembly are fixedly connected through the flexible connecting piece, the edge of the radiation main body and the edge of the circuit board assembly can be kept relatively fixed, that is, the radiation main body is fixed to the edge of the circuit board assembly, so that the radiation main body and the circuit board assembly are not stacked in the thickness direction of the electronic device, which is beneficial to reduce the overall size of the electronic device.
