[0046] The technical solutions in the embodiments (or, implementations) of the present disclosure will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0047] If the present disclosure embodiments involve directional indications or positional relationships (for example, up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a certain posture (as shown in the drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. in the present disclosure embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0048] In order to facilitate understanding of the technical solutions of the present disclosure, the antenna structure and electronic device of the present disclosure will be described in detail below in conjunction with the accompanying drawings. In the case of no conflict, the features in the following embodiments and implementations can be combined with each other.

[0049] Referring to Figures 1 to 3As shown, the embodiment of the present disclosure provides an antenna structure 100, which can be applied to electronic products such as mobile phones, tablets, notebooks, smart glasses, smart watches, smart bracelets, wearable devices, etc. The antenna structure 100 can include a metal middle frame 10 and an electrical element 20 mounted on the metal middle frame 10. The electrical element 20 includes a conductive layer 21, which is electrically connected to the metal middle frame 10. The electrical element 20 and the metal middle frame 10 enclose a cavity antenna 30 with an opening 31, which can serve as a radiation aperture of the antenna. Optionally, the conductive layer 21 can be a conductive copper layer or a copper foil layer. Alternatively, it can be a flexible printed circuit (FPC) or other conductive layer, such as a laser direct structuring (LDS) layer, a printing direct structure (PDS) layer, etc. The cavity antenna 30 can be used as a GPS antenna or other types or frequency bands of antennas as needed.

[0050] As can be seen from the above embodiment, the antenna structure 100 of the present disclosure uses the metal middle frame 10 and the electrical element 20 to enclose a cavity with an opening 31, thereby constituting a cavity antenna 30. This can reduce the risk of uncertain electrical connection, maintain the sealing of the cavity, increase the performance of the entire antenna cavity, improve the performance of the antenna, and reduce the cost and production risk. Moreover, the use of the conductive layer structure can increase the flexibility of debugging and reduce the proofing cycle.

[0051] In some optional embodiments, the opening side of the cavity antenna 30 (i.e., the side where the opening 31 is located) can be provided with a feeding member as a feeding point, which is electrically connected to the conductive layer 21 to realize coupled feeding of the cavity antenna for signal feeding.

[0052] In some optional embodiments, the antenna structure 100 can further include an electrical connecting member 40 connected between the metal middle frame 10 and the electrical element 20 at a portion not corresponding to the opening 31, to realize electrical connection between the electrical element 20 and the metal middle frame 10. Optionally, the electrical connecting member 40 can be subjected to a sealing grounding process to improve the stability of the cavity antenna.

[0053] In combination with Figure 2As shown, in this embodiment, there are multiple electrical connectors 40, spaced apart circumferentially along the electrical element 20, improving the connection reliability between the electrical element 20 and the metal frame 10. For example, taking a rectangular electrical element 20 as an example, multiple electrical connectors 40 are spaced apart along three sides of the electrical element 20, thereby forming a cavity antenna 30 that is enclosed on three sides and open on one side. The side without electrical connectors 40 forms the opening 31. Combined with... Figure 3 As shown, in this embodiment, the electrical connector 40 can also be a long strip structure arranged along three sides of the electrical element 20, thereby forming a cavity antenna 30 that is enclosed on three sides and open on one side. The side without the electrical connector 40 forms the opening 31, thereby improving the overall performance of the antenna cavity. Optionally, the electrical connector 40 may include conductive foam, conductive silicone, conductive cloth, conductive metal sheet, metal spring, etc.

[0054] In some optional embodiments, the electrical component 20 includes a display screen, and the opening 31 corresponds to the top or bottom side of the display screen. It is understood that the electrical connectors are spaced apart circumferentially along the display screen, which improves the connection reliability between the electrical component 20 and the metal frame 10, and also allows the opening 31 to match the size of the top or bottom side of the display screen, so that the entire top or bottom side of the display screen can serve as an antenna radiating port to radiate signals outwards. It should be noted that the electrical component 20 can also be other devices that can form a cavity antenna with the metal frame; this disclosure does not impose any limitations on this. Optionally, the conductive layer 21 is a copper foil layer (CU) or a flexible printed circuit board (FPC) disposed on the display screen, i.e., the CU layer of the display screen or a large-area FPC layer.

[0055] In this way, by using the display screen and the metal frame to form a cavity antenna, both the use of the display screen and the implementation of the antenna scheme can be taken into account. By aligning the opening 31 with the top or bottom side of the display screen, the user's fingers can be less likely to block the antenna when holding the device, thus reducing the amplitude drop in the closed state.

[0056] See Figure 4 and Figure 5 As shown, it is understandable. Figure 4 It can be understood as along Figure 5 A stacked schematic diagram of a cross-sectional view along the AA direction. In some alternative embodiments, the antenna structure 100 may further include a circuit board 50 mounted on the metal frame 10. One side of the circuit board 50 is electrically connected to the metal frame 10, and the other side is electrically connected to the display screen. Thus, both the display screen and the circuit board 50 are electrically connected, and the circuit board 50 can also be used to electrically connect the display screen to the metal frame 10, thereby forming the cavity antenna by the display screen and the metal frame 10.

[0057] In some alternative embodiments, the antenna structure 100 can further comprise a mounting bracket 60, which can be fixedly connected with the metal middle frame 10 by screws or other fasteners, and the circuit board 50 is arranged on the mounting bracket 60. In this way, the mounting bracket 60 can be used to mount electronic devices of the electronic device, and also can support the circuit board 50, increase the stability of the circuit board, and provide better structural strength. Alternatively, the mounting bracket 60 can be a plastic bracket or a bracket of other insulating material, which can support the circuit board 50, increase the stability of the circuit board, and provide better structural strength. Further, holes can be formed between the mounting bracket 60 and the circuit board 50 at corresponding positions, and the mounting bracket 60 and the circuit board 50 can be connected by screws or other connecting members, to ensure the stability of the circuit board.

[0058] Referring to Figure 6 Further, as shown in the drawings, the antenna structure 100 can further comprise a camera module 90, which is mounted on the mounting bracket 60 and electrically connected with the circuit board 50. In this way, the mounting bracket 60 can support the circuit board 50, and also can be used to mount electronic devices such as the camera module 90 and other electronic devices.

[0059] In some alternative embodiments, the metal middle frame 10 comprises a mounting area 11 for mounting electronic devices of the electronic device, and the mounting area 11 can be used to mount electronic devices such as the camera module.

In this way, the circuit board 50 is electrically connected with the metal middle frame 10 and the electrical element 20 in the mounting area 11, to realize the electrical connection of the metal middle frame 10 and the electrical element 20.

[0060] Further, the antenna structure 100 can further comprise a first electrical connecting member 41, a second electrical connecting member 42 and a third electrical connecting member 43, the first electrical connecting member 41 is connected between the circuit board 50 and the electrical element 20, the second electrical connecting member 42 is connected between the metal middle frame 10 and the electrical element 20 at a portion not corresponding to the opening 31, and the third electrical connecting member 43 is connected between the circuit board 50 and the metal middle frame 10. In this way, in the installation area 11, the circuit board 50 is electrically connected to the electrical element 20 through the first electrical connecting member 41, and is electrically connected to the metal middle frame 10 through the third electrical connecting member 43, so as to realize electrical connection between the metal middle frame 10 and the electrical element 20 at the portion in the installation area 11. Outside the installation area 11, the metal middle frame 10 and the electrical element 20 are directly electrically connected through the second electrical connecting member 42. Optionally, the first electrical connecting member 41, the second electrical connecting member 42 and the third electrical connecting member 43 can each comprise conductive foam, conductive silica gel, conductive cloth, conductive metal sheet, metal spring sheet, etc.

[0061] In the embodiment, the first electrical connecting member 41 is one or more, and the second electrical connecting member 42 is one or more, and the first electrical connecting member 41 and the second electrical connecting member 42 are jointly and spacedly arranged along the circumference of the electrical element 20. For example, taking the electrical element 20 as a rectangle, the first electrical connecting member 41 and the second electrical connecting member 42 are jointly and spacedly arranged along three edges of the electrical element 20, so as to form a cavity antenna 30 with three closed sides and one open side, and the edge without the first electrical connecting member 41 and the second electrical connecting member 42 forms the opening 31. It should be noted that when the circuit board 50 is arranged on the side of the installation support 60 facing the metal middle frame 10, the position of the first electrical connecting member 41 needs to avoid the installation support 60. When the circuit board 50 is arranged on the side of the installation support 60 away from the metal middle frame 10, the position of the third electrical connecting member 43 needs to avoid the installation support 60. So as to ensure the reliability of the electrical connection between the circuit board 50 and the metal middle frame 10.

[0062] In some optional embodiments, the antenna structure 100 can further comprise an installation support 60 for installing electronic devices, which is fixedly connected to the metal middle frame 10 from the installation area 11, and the circuit board 50 is arranged on the installation support 60.

Optionally, the installation support 60 can be a plastic support or a support made of other insulating materials, which can support the circuit board 50, increase the stability of the circuit board, and provide better structural strength. Further, holes can be formed between the installation support 60 and the circuit board 50 at corresponding positions, and the installation support 60 and the circuit board 50 can be connected to each other through screws or other connecting members, so as to ensure the stability of the circuit board.

[0063] Further, the antenna structure 100 can further include fasteners 70, which pass through the mounting bracket 60 and the circuit board 50, and are fixedly connected with the metal middle frame 10, so as to fix the mounting bracket 60, the circuit board 50 and the metal middle frame 10. Optionally, the fasteners 70 can be screws.

[0064] Referring to Figures 1 to 7 The embodiment of the present disclosure further provides an electronic device 200, which can be a mobile phone or other electronic product. The electronic device 200 can include the antenna structure 100 as described in the above embodiments.

[0065] As can be seen from the above embodiments, the electronic device 200 and the antenna structure 100 of the present disclosure utilize the metal middle frame 10 and the electric element 20 to form a cavity with an opening 31, thereby constituting a cavity antenna 30. This can reduce the risk of uncertain electrical connection, and can perfectly maintain the sealing of the cavity, thereby increasing the performance of the entire antenna cavity, improving the antenna performance, reducing the cost and the risk of mass production. Moreover, the structure of the conductive layer can increase the flexibility of debugging and reduce the proofing cycle.

[0066] In some optional embodiments, the electronic device 200 can include a first display screen 80, and the electric element 20 is arranged on one side of the metal middle frame 10, and the first display screen 80 is mounted on the side of the metal middle frame 10 opposite to the electric element 20. It can be understood that the electric element 20 can be a display screen, or a back cover of the electronic device. In this way, the display screen or the back cover and the metal middle frame can be utilized to form the cavity antenna. Optionally, the electronic device 200 can further include a camera module 90 mounted in the mounting bracket 60 from the mounting area 11 of the metal middle frame 10.

[0067] In some optional embodiments, the electric element 20 can include a second display screen, the opening 31 corresponds to the top side or the bottom side of the second display screen, and the area of the second display screen is smaller than the area of the first display screen 80. It can be understood that the first display screen 80 can be understood as the main screen of the electronic device, and the second display screen can be understood as the auxiliary screen of the electronic device.

[0068] In this way, the auxiliary screen and the metal middle frame are utilized to form the cavity antenna, which can take into account the use of the display screen and the implementation of the antenna scheme. The opening 31 corresponds to and matches the size of the top side or the bottom side of the auxiliary screen, and the entire top side or the bottom side of the auxiliary screen can be used as an antenna radiation port to radiate signals outward, which can reduce the shielding of the antenna by the user's fingers when the user holds the electronic device, and reduce the closed state amplitude reduction.

[0069] Referring to Figure 8 and Figure 9As shown, in some optional embodiments, the metal middle frame 10 includes a first shell 12 and a second shell 13, and the second shell 13 is foldably connected with the first shell 12. The first display screen 80 includes a first flexible screen 81 and a second flexible screen 82, and the second flexible screen 82 is foldably connected with the first flexible screen 81. The first flexible screen 81 is arranged corresponding to the first shell 12, and the second flexible screen 82 is arranged corresponding to the second shell 13. When the electronic element 20 is the second display screen, it is arranged on the side of the first shell 12 opposite to the first flexible screen 81. The electronic device 200 can further include a rear shell 91 arranged on the side of the second shell 13 opposite to the second flexible screen 82. It can be understood that the electronic device 200 of the embodiment is a folding mobile phone. It can be a small folding Flip folding mobile phone, that is, the first shell 12 and the second shell 13 are folded along a set direction X, and the set direction X is parallel to the direction of the short side of the metal middle frame 10, as shown in Figure 8 and Figure 9 . It can also be a large folding Fold folding mobile phone, that is, the first shell 12 and the second shell 13 are folded along a set direction, and the set direction is parallel to the direction of the long side of the metal middle frame 10.

[0070] As shown in Figure 8 , Figure 10 and Figure 11 , in combination with Figure 8 , the cavity antenna scheme of the present disclosure is arranged corresponding to the top side of the secondary screen and matches the size of the secondary screen, and the entire top side of the secondary screen can be used as an antenna radiation port to radiate signals outward, the radiation aperture is expanded, the signal interference between the antennas located at the top of the first shell and the second shell in the closed state is reduced, the user's fingers are shielded when the user holds the device, and the closed state amplitude is reduced, as shown in Figure 11 , thereby improving the performance of the antenna.

[0071] In combination with Figure 10 , in the related art, the antenna of the conventional folding mobile phone is located at the upper left corner of the back view of the whole machine, as shown in Figure 10 , which is a conventional IFA frame antenna scheme. The performance of this scheme in the unfolded state is not much different from that of a straight mobile phone. However, in the closed state, there is signal interference between the antennas located at the top of the first shell and the second shell, and the antennas are shielded by the user's fingers due to the user's holding relationship, as shown in Figure 11 , which affects the performance of the antenna and the user experience.

[0072] In some optional embodiments, the metal middle frame 10 is rectangular, and the first shell 12 and the second shell 13 are folded relative to each other along a set direction X, which is parallel to the direction of the short side of the metal middle frame 10. It can be understood that the electronic device 200 of the embodiment is a Flip form folding mobile phone, which has a fashionable appearance after folding, is small and exquisite, and has the advantages of practicality, and is increasingly popular among users.

[0073] Unlike the frame antenna scheme of the conventional mobile phone in the related art, the Flip form folding mobile phone of the present disclosure adopts the above-mentioned antenna structure 100, uses the sub-screen and the metal middle frame to form a cavity antenna, can consider the use of the display screen and the implementation of the antenna scheme, and can simultaneously consider the performance in the unfolded and closed states. When the cavity antenna is used as a GPS antenna, the GPS positioning and navigation function is a strong demand point of user experience, and the unfolded and closed states have good antenna performance to ensure the accuracy of positioning. After the mobile phone is closed, the closed state has basically no decrease, and the cavity antenna can also radiate signals through the opening, and the closed handheld will not hold the radiator, which can simultaneously consider compatible with multiple hand holding postures, thereby maximizing the antenna performance and providing the user with the optimal navigation and positioning experience. Moreover, the signal interference between antennas can be reduced, and the influence of user holding on the antenna can be reduced, thereby ensuring good positioning accuracy.
