Technical Field

[0002] The present application relates to the field of antenna technology, and in particular to an electronic device. Background Art

[0003] With users demanding more functionality and aesthetics from their devices, integrated mid-frame designs are becoming mainstream. For example, more and more mobile phones are adopting an integrated back cover and mid-frame structure. This integrated mid-frame structure makes traditional separate mid-frame antenna designs no longer suitable.

[0004] In the related art, for mobile phones with an integrated middle frame structure, the alloy insert inherent in the integrated middle frame is usually used as the mobile phone antenna. The alloy insert needs to be divided into multiple relatively independent insert structures, and the antenna feed point where the alloy insert is connected to the mobile phone's circuit board needs to be spot-welded with gold-plated copper foil.

[0005] However, the above-mentioned antenna configuration method has the problems of poor configuration flexibility and high cost. Summary of the Invention

[0006] The embodiments of the present application provide an antenna assembly and an electronic device, which can improve the configuration flexibility of the antenna assembly and reduce the cost of the antenna assembly.

[0008] an antenna bracket, the antenna bracket being accommodated in the gap, and one end of the antenna bracket being fixedly connected to the middle frame;

[0009] The flexible radiator is used to support the antenna bracket, and the flexible radiator is electrically connected to the circuit board to transmit and receive signals.

[0010] In a second aspect, an electronic device is provided.

[0014] The antenna assembly of the embodiment of the present application is used in an electronic device, which includes a middle frame and a shell with an integral structure. A circuit board is provided on the middle frame, and there is a gap between the circuit board and the shell. The antenna assembly includes an antenna bracket and a flexible radiator. The antenna bracket is used to support the flexible radiator. The antenna bracket is accommodated in the above-mentioned gap and one end of the antenna bracket is fixedly connected to the middle frame. The flexible radiator and the circuit board are electrically connected to receive and transmit signals. In this way, the embodiment of the present application provides an antenna bracket in the gap between the circuit board and the shell to support the flexible radiator to achieve antenna performance, without having to use an alloy insert in the middle frame of the integral structure as an antenna as in traditional technology. The alloy insert needs to be divided into multiple relatively independent insert structures. Under normal circumstances, in order to facilitate molding processing, the multiple independent insert structures need to be connected by a connecting material structure, and then CNC (Computerized Numerical) is performed after molding is completed.

[0025] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0027] It will be understood that the terms "first," "second," etc., used herein may be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, a first resistor may be referred to as a second resistor, and similarly, a second resistor may be referred to as a first resistor without departing from the scope of this application. The first resistor and the second resistor are both resistors, but they are not the same resistor.

[0028] It can be understood that the “connection” in the following embodiments should be understood as “electrical connection”, “communication connection”, etc. if there is transmission of electrical signals or data between the connected circuits, modules, units, etc.

[0029] As used herein, the singular forms "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include," "comprising," "having," and the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Furthermore, the term "and / or" as used in this specification includes any and all combinations of the relevant listed items.

[0030] The antenna of an electronic device is an essential component for communication. Taking a mobile phone as an example, in a conventional split midframe, the antenna is located on the inner surface of the B shell (i.e., the midframe). This antenna design provides a large antenna routing area and clearance, resulting in better antenna performance.

[0031] As users demand more functionality and appearance, unibody mid-frame phones have become mainstream. Currently, more and more phones are adopting a one-piece back cover and mid-frame structure. However, the antenna design solution mentioned above for a separate mid-frame is no longer applicable to phones with an unibody mid-frame structure.

[0032] In the related art, please refer to Figure 1, which is an exemplary schematic diagram of the antenna setting of a mobile phone with an integrated middle frame. For mobile phones with an integrated middle frame structure, the alloy inserts inherent in the integrated middle frame are generally used as mobile phone antennas. The alloy inserts need to be divided into multiple relatively independent insert structures. Usually, in order to facilitate molding processing, the multiple independent insert structures need to be connected with a connecting material structure, and CNC cutting is performed after molding is completed. This will lead to complicated antenna molding processing, long production cycle and high antenna costs.

[0033] Furthermore, to improve the contact reliability between the alloy insert and the phone's circuit board, the antenna feed point where the alloy insert connects to the phone's circuit board currently requires riveting or spot welding gold-plated copper foil, further increasing the antenna's material and processing costs. Consequently, conventional antenna placement methods for integrated mid-frame structures suffer from limited flexibility and high costs.

[0034] In view of this, embodiments of the present application provide an antenna assembly and electronic device that can improve the flexibility of antenna assembly installation in electronic devices and reduce the cost of the antenna assembly. The following, in conjunction with the accompanying drawings, exemplarily illustrates the implementation of the antenna assembly and electronic device provided in embodiments of the present application.

[0035] The antenna assembly provided in the embodiments of the present application can be set in an electronic device, which may include, for example, a smart phone, a tablet computer, an Internet of Things device, and a portable wearable device. The Internet of Things device may be a smart speaker, a smart TV, a smart air conditioner, a smart car-mounted device, a smart car, etc. The portable wearable device may be a smart watch, a smart bracelet, a head-mounted device, etc.

[0036] In one embodiment, see Figure 2, which is a cross-sectional view of an electronic device along a first direction when an antenna assembly provided by an embodiment of the present application is disposed in the electronic device. For example, in the case of a smartphone, the first direction may be parallel to the display screen of the smartphone.

[0037] The electronic device in the embodiment of the present application includes a middle frame and a shell with an integrated structure, that is, the electronic device adopts an integrated middle frame structure, and a circuit board is arranged on the middle frame. The circuit board can be composed of a multi-layer circuit board, electronic components and connecting lines to realize various functions of the electronic device.

[0038] There is a gap between the circuit board and the shell, that is, the circuit board set on the middle frame is not completely fitted with the shell, but there is a cavity part, and the antenna assembly provided by the implementation of this application can be set in the gap.

[0039] Exemplarily, the antenna assembly may include an antenna bracket and a flexible radiator. The antenna bracket is accommodated in the gap between the circuit board and the housing, with one end of the antenna bracket fixedly connected to the middle frame and the other end of the antenna bracket being free. The antenna bracket is used to support the flexible radiator, which is electrically connected to the circuit board for signal transmission and reception.

[0040] Exemplarily, the antenna bracket may be made of an insulating material, for example, the antenna bracket is a plastic bracket; the flexible radiator may be an FPC (Flexible Printed Circuit) antenna body.

[0041] In this way, for electronic devices with an integrated structure of the middle frame and the shell, antenna performance is achieved by arranging an FPC on the plastic bracket. Compared with the traditional method of using the alloy insert inherent in the integrated middle frame as the mobile phone antenna, there is no need to divide the alloy insert into multiple relatively independent insert structures, nor is there any need to connect the multiple independent insert structures with a continuous material structure during the molding process, and then perform CNC cutting after the molding is completed. The manufacturing process of the antenna bracket and the flexible radiator in the embodiment of the present application is simple and low-cost, thereby shortening the processing cycle of the antenna assembly and reducing the cost of the antenna assembly.

[0042] The following is an exemplary description of possible shapes of the antenna bracket and the arrangement of the flexible radiator on the antenna bracket. First, the possible shapes of the antenna bracket are introduced.

[0043] For example, there may be multiple antenna assemblies, each of which includes at least one antenna bracket and a flexible radiator. The multiple antenna assemblies may include, for example, a cellular antenna assembly, a GPS (Global Positioning System) antenna assembly, a WiFi (Wireless Fidelity) antenna assembly, and the like.

[0044] Among them, different antenna components can be set at different positions of the electronic device, such as on the top, bottom or side of the electronic device. Taking the top of the electronic device as an example, different antenna components can be set at both ends of the top respectively.

[0045] The shape of the gap between the circuit board and the housing of an electronic device may also vary at different locations. To better utilize the gap between the circuit board and the housing and improve the antenna performance of the antenna assembly, the shape of the antenna bracket in the embodiment of the present application can match the shape of the gap used to accommodate the antenna bracket. Matching means that the shape of the antenna bracket can be a shape that is a predetermined ratio smaller than the shape of the corresponding gap. This ensures that the antenna bracket can still be accommodated in the gap after supporting the flexible radiator, thereby preventing additional increase in the size of the electronic device.

[0046] In other possible implementations, each antenna bracket may also be of a uniform fixed shape, and the fixed shape can be accommodated in gaps at different positions of the electronic device, which can further reduce the processing difficulty and save processing costs.

[0047] Next, the arrangement of the flexible radiator on the antenna bracket is introduced.

[0048] In the embodiment of the present application, the flexible radiator can be attached to multiple surfaces of the antenna bracket, and the multiple surfaces at least include a surface parallel to the circuit board and a surface perpendicular to the circuit board.

[0049] For example, referring to FIG3 and FIG4 , FIG3 is a schematic diagram of an exemplary antenna assembly at a first viewing angle, and FIG4 is a schematic diagram of an exemplary antenna assembly at a second viewing angle.

[0050] As shown in Figures 3 and 4, the flexible radiator is attached to two surfaces of the antenna bracket, which include a surface parallel to the circuit board and a surface perpendicular to the circuit board. In this way, the flexible radiator on the surface parallel to the circuit board can provide radiation performance in the x and y directions, and the flexible radiator on the surface perpendicular to the circuit board can provide radiation performance in the z direction.

[0051] The configuration of the antenna assembly in the embodiment of the present application not only ensures antenna performance, but also enables a lower-cost FPC antenna to be implemented in an electronic device with an integrated middle frame structure, thereby improving the configuration flexibility of the antenna assembly.

[0052] In one embodiment, please continue to refer to Figure 2. The antenna assembly of the embodiment of the present application also includes an antenna shrapnel. The antenna shrapnel can be a metal shrapnel or an alloy shrapnel. The flexible radiator is electrically connected to the circuit board through the antenna shrapnel. Through the antenna shrapnel, good contact and conduction between the flexible radiator and the circuit board can be achieved.

[0053] Optionally, as shown in Figure 2, the flexible radiator is electrically connected to the circuit board through the antenna shrapnel at the free end of the antenna bracket; optionally, the flexible radiator can also be electrically connected to the circuit board through the antenna shrapnel at the end where the antenna bracket is fixedly connected to the middle frame. There is no specific restriction on the position of the antenna shrapnel.

[0054] Overall, the above embodiment sets an antenna bracket in the gap between the circuit board and the shell to support the flexible radiator to achieve antenna performance. The manufacturing process of the antenna assembly is simple and the antenna cost is greatly reduced. In addition, there is no need to spot weld gold-plated copper foil at the connection position between the flexible radiator and the circuit board to increase contact reliability, thereby further reducing the cost of the antenna assembly and making the setting of the antenna assembly more flexible.

[0055] Based on any one of the embodiments shown in Figures 2 to 4, this embodiment introduces the configuration of each antenna assembly in an electronic device when there are multiple antenna assemblies, wherein the configuration positions of the multiple antenna assemblies in the electronic device do not overlap, and each antenna assembly may include at least one set of the above-mentioned antenna brackets and flexible radiators.

[0056] In the embodiment of the present application, the multiple antenna assemblies include a main set cellular antenna assembly and a diversity cellular antenna assembly, and the main set cellular antenna assembly and the diversity cellular antenna assembly are both used to transmit and receive cellular signals.

[0057] Several possible installation positions of the main cellular antenna assembly and the diversity cellular antenna assembly in the electronic device are exemplarily described below.

[0058] 1) Please refer to FIG5 , which is a schematic diagram of an exemplary arrangement of a main cellular antenna assembly and a diversity cellular antenna assembly in an electronic device.

[0059] As shown in FIG5 , the primary cellular antenna assembly is arranged at the bottom of the electronic device, and the diversity cellular antenna assembly is arranged at the top of the electronic device. ANT0 (antenna 0) shown in FIG5 is the primary cellular antenna assembly (PRX, English: Primary Receive, Chinese: Primary Receive) and ANT1 (antenna 1) shown in FIG5 is the diversity cellular antenna assembly (DRX, English: Diversity Receive, Chinese: Diversity Receive).

[0060] Both the main and diversity cellular antenna assemblies support the transmission and reception of cellular signals in the LB (Low Band) and MHB (Middle High Band) frequency bands. During use, if the main cellular antenna assembly is blocked or other scenarios that affect the transmission and reception of cellular signals, you can switch to the diversity cellular antenna assembly to transmit and receive cellular signals, thereby improving signal transmission and reception reliability.

[0061] 2) This embodiment is similar to the embodiment shown in FIG5 in that the main cellular antenna assembly is disposed at the bottom of the electronic device, and the main cellular antenna assembly supports the transmission and reception of cellular signals in the LB and MHB frequency bands.

[0062] The difference between this embodiment and the embodiment shown in Figure 5 is that the diversity cellular antenna assembly is split into a low-frequency diversity cellular antenna assembly and a medium- and high-frequency diversity cellular antenna assembly. The low-frequency diversity cellular antenna assembly supports the transmission and reception of cellular signals in the LB band, and the medium- and high-frequency diversity cellular antenna assembly supports the transmission and reception of cellular signals in the MHB band. Then, the low-frequency diversity cellular antenna assembly and the medium- and high-frequency diversity cellular antenna assembly are arranged on the top and / or the side of the electronic device.

[0063] In a possible implementation, please refer to FIG6 , which is a schematic diagram of exemplary installation positions of a main cellular antenna assembly and a diversity cellular antenna assembly in an electronic device according to this embodiment.

[0064] As shown in FIG6 , the low-frequency diversity cellular antenna assembly ( ANT1 shown in FIG6 ) is disposed on the top of the electronic device, and the mid- and high-frequency diversity cellular antenna assembly ( ANT2 shown in FIG6 ) is disposed on the side of the electronic device.

[0065] In another possible implementation, the low-frequency diversity cellular antenna assembly may also be disposed on the side of the electronic device, and the mid- and high-frequency diversity cellular antenna assembly may be disposed on the top of the electronic device.

[0066] By separating the diversity cellular antenna assembly and placing the low-frequency and mid- and high-frequency diversity cellular antenna assemblies on the sides of the electronic device, the attenuation of antenna performance in head-to-hand mode is reduced. Furthermore, separating the diversity cellular antenna assembly allows for greater flexibility in antenna performance testing.

[0067] In this embodiment, the low-frequency diversity cellular antenna assembly / medium-high frequency diversity cellular antenna assembly in the diversity cellular antenna assembly is arranged on the side of the electronic device, which can be the side of the electronic device where the volume button is not arranged. This can reduce the difficulty of antenna routing and help improve antenna performance.

[0068] 3) This embodiment is similar to the embodiment shown in FIG5 in that the diversity cellular antenna assembly is disposed on the top of the electronic device, and the diversity cellular antenna assembly supports the transmission and reception of cellular signals in the LB and MHB frequency bands.

[0069] The difference between this embodiment and the embodiment shown in Figure 5 is that the main set cellular antenna assembly is split into a low-frequency main set cellular antenna assembly and a medium- and high-frequency main set cellular antenna assembly. The low-frequency main set cellular antenna assembly supports the transmission and reception of cellular signals in the LB frequency band, and the medium- and high-frequency main set cellular antenna assembly supports the transmission and reception of cellular signals in the MHB frequency band. Then, the low-frequency main set cellular antenna assembly and the medium- and high-frequency main set cellular antenna assembly are arranged at the bottom and / or the side of the electronic device.

[0070] In a possible implementation, please refer to FIG. 7 , which is a schematic diagram of exemplary installation positions of a main cellular antenna assembly and a diversity cellular antenna assembly in an electronic device according to this embodiment.

[0071] As shown in FIG7 , the low-frequency main cellular antenna assembly (such as ANT0 shown in FIG7 ) is arranged on the side of the electronic device, and the medium- and high-frequency main cellular antenna assembly (such as ANT2 shown in FIG7 ) is arranged on the bottom of the electronic device.

[0072] In another possible implementation, the low-frequency main cellular antenna assembly may also be disposed at the bottom of the electronic device, and the mid- and high-frequency main cellular antenna assembly may be disposed at the side of the electronic device.

[0073] By splitting the main cellular antenna assembly and placing the low-frequency and mid- and high-frequency components on the sides of the electronic device, the attenuation of antenna performance in head-to-hand mode is reduced. Furthermore, splitting the main cellular antenna assembly allows for greater flexibility in antenna performance testing.

[0074] Similar to the embodiment shown in Figure 6, this embodiment arranges the low-frequency main cellular antenna assembly / medium-high frequency main cellular antenna assembly in the main cellular antenna assembly on the side of the electronic device, which can be the side of the electronic device where the volume button is not set. This can reduce the difficulty of antenna routing and help improve antenna performance.

[0075] The above description exemplifies several possible locations of the main cellular antenna assembly and the diversity cellular antenna assembly in the electronic device.

[0076] In an embodiment of the present application, both the main cellular antenna assembly and the diversity cellular antenna assembly include a switching circuit and an impedance matching circuit. The switching circuit is used to switch the operating frequency of the main cellular antenna assembly / diversity cellular antenna assembly, and the impedance matching circuit is used to perform RF impedance matching on the main cellular antenna assembly / diversity cellular antenna assembly.

[0077] For example, please refer to FIG8 , which is a circuit diagram of a switching circuit and an impedance matching circuit of an exemplary main cellular antenna assembly. The main cellular antenna assembly may be arranged in the electronic device at a position as shown in FIG5 .

[0078] Among them, the switching circuit is connected to the tuning point position of the main set cellular antenna assembly through a spring clip. The switching circuit adjusts the medium and low frequencies of the main set cellular antenna assembly by adjusting the return path (RF1, RF2, RF3 or RF4 as shown in Figure 8). 13124c shown in Figure 8 is the switching assembly.

[0079] The impedance matching circuit is connected to the main set cellular antenna assembly through a spring clip. The impedance matching circuit can perform radio frequency impedance matching on the main set cellular antenna assembly, so that the impedance of the main set cellular antenna assembly is close to 50 ohms.

[0080] In this way, this embodiment can automatically adjust the operating frequency of the main cellular antenna assembly / diversity cellular antenna assembly through the switching circuit, making the antenna assembly more intelligent.

[0081] Please refer to Figure 9, which is a schematic diagram of the return loss of the main cellular antenna assembly in one embodiment. The horizontal axis in Figure 9 is the frequency range of 0-4GHZ. In Figure 9, the curves corresponding to numbers 119, 120, 210, 225, and 255 are schematic diagrams of the return loss of the switching circuit shown in Figure 8 in the four modes RF1-RF4 and when the switch is closed. It can be seen from Figure 9 that the main cellular antenna assembly in the embodiment of the present application has good return loss performance.

[0082] Based on the embodiment shown in FIG. 5 above, in this embodiment, in addition to the main cellular antenna assembly and the diversity cellular antenna assembly, the multiple antenna assemblies also include at least one of a GPS antenna assembly, a WiFi antenna assembly, and an NFC antenna assembly.

[0083] Among them, the GPS antenna assembly is used to transmit and receive GPS signals, the WiFi antenna assembly is used to transmit and receive WiFi signals, and the NFC antenna assembly is used to transmit and receive NFC signals.

[0084] The following is an exemplary description of how the GPS antenna assembly, the WiFi antenna assembly, and the NFC antenna assembly are arranged in an electronic device.

[0085] Please refer to FIG. 10 , which is a schematic diagram illustrating exemplary placement of a GPS antenna assembly, a WiFi antenna assembly, and an NFC (Near Field Communication) antenna assembly in an electronic device.

[0086] As shown in FIG10 , the GPS antenna assembly is disposed on the top of the electronic device so that the GPS antenna assembly can transmit and receive GPS signals. Specifically, when the main cellular antenna assembly is also disposed on the top of the electronic device, the GPS antenna assembly and the main cellular antenna assembly are respectively disposed at the two ends of the top of the electronic device; and when the diversity cellular antenna assembly is disposed on the top of the electronic device, the GPS antenna assembly and the diversity cellular antenna assembly are respectively disposed at the two ends of the top of the electronic device.

[0087] Continuing to refer to FIG10 , the multiple antenna components further include an NFC antenna component, which is used to transmit and receive NFC signals.

[0088] Please continue to refer to Figure 10. The WiFi antenna assembly is arranged on the side of the electronic device. The WiFi antenna assembly is arranged close to the GPS antenna assembly. This is conducive to the WiFi antenna assembly and the GPS antenna assembly sharing the signal transceiver chip. The side of the electronic device where the WiFi antenna assembly is arranged can be the side of the electronic device where the volume button is arranged. In this way, the WiFi antenna assembly can be staggered with the main cellular antenna assembly and the diversity cellular antenna assembly, which are split to the antenna assembly at the waist of the electronic device, which is conducive to improving communication quality.

[0089] Based on the same inventive concept, an embodiment of the present application also provides an electronic device, which includes a middle frame and a shell with an integrated structure, a circuit board arranged on the middle frame, and the antenna assembly described in any of the above embodiments. There is a gap between the circuit board and the shell. The antenna assembly includes an antenna bracket and a flexible radiator. The antenna bracket is accommodated in the gap, and one end of the antenna bracket is fixedly connected to the middle frame. The antenna bracket is used to support the flexible radiator. The flexible radiator and the circuit board are electrically connected for signal reception and transmission.

[0090] The implementation solution provided by the electronic device to solve the problem is similar to the implementation solution described in the embodiment of the above antenna assembly. Please refer to the above definition of the antenna assembly and will not be repeated here.

[0091] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application.
