[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0046] This disclosure provides an electronic device including an antenna radiator and a feed unit. The antenna radiator is disposed on a hinge cover of the electronic device. When the two folded parts are in the folded state, the hinge cover is exposed between the two folded parts. The feed unit is used to feed power to the antenna radiator. In this disclosure, by disposing of the antenna radiator on the hinge cover, the antenna radiator has a larger clearance area. Furthermore, the size of the hinge cover is larger than the size of any single folded part of the electronic device, thereby facilitating the placement of antenna radiators with larger radiating surfaces and various forms, thus improving the wireless communication performance of the electronic device in the folded state.

[0047] According to an exemplary embodiment of this disclosure, such as Figure 1 and Figure 2 As shown, this embodiment provides an electronic device 100, such as a foldable screen phone, a laptop computer, or other electronic products with flipping or folding functions. (See reference...) Figure 1 The electronic device 100 includes a hinge (not shown in the figures) and two folding portions 30. The two folding portions 30 are mechanically connected by the hinge. The two folding portions 30 can be opened / unfolded or folded relative to the hinge to switch the electronic device 100 between a use state and a storage state, or to allow the user to use the electronic device 100 in different ways. See also Figure 1 The electronic device 100 also includes a hinge cover 20, which is a structure located on the outside of the hinge in the electronic device 100 and is used to protect the hinge when the electronic device 100 is in a folded state.

[0048] like Figure 1 and Figure 2 As shown, the electronic device 100 also includes an antenna device 10 consisting of an antenna radiator 11 and a power supply unit 12. The antenna radiator 11 is disposed on the hinge cover 20 of the electronic device 100. The power supply unit 12 can be electrically connected to the main board, antenna board, or other circuit boards of the electronic device 100 to receive power provided by the electronic device 100 and to power the antenna radiator 11 to excite the antenna radiator 11 to generate a target frequency band resonant signal. The power supply methods include, but are not limited to, direct power supply through physical connection and electromagnetic coupling power supply.

[0049] It should be noted that when the electronic device 100 with flip and folding functions is in the folded state, the hinge cover 20 will be exposed to the outside of the electronic device 100. Therefore, placing the antenna radiator 11 on the hinge cover 20 can give the antenna radiator 11 a larger clearance area, thereby enhancing the wireless communication performance of the electronic device 100 in the folded state. Additionally, see [link to relevant documentation]. Figure 1 Along the thickness direction of electronic device 100 ( Figure 1 (as shown in the z-direction), the dimension h1 of the hinge cover 20 is typically larger than the dimension of the mid-frame of any single fold 30 of the electronic device 100, for example, Figure 1 h2 and h3 in the figure, therefore, it is advantageous to realize antenna radiators 11 with a larger radiating surface and various forms on the hinge cover 20, thereby improving the wireless communication performance of the electronic device 100 in the folded state.

[0050] In one embodiment, such as Figures 2 to 6 As shown, the antenna radiator 11 can be formed by the pivot cover 20. For example, the conductive structure of the pivot cover 20 forms the antenna radiator 11, or the gap 27 in the pivot cover 20 forms the antenna radiator 11.

[0051] In another embodiment (not shown in the figures), the hinge cover 20 serves as a substrate for carrying the antenna radiator 11, and the antenna radiator 11 can be disposed on the hinge cover 20 by means of laser-direct-structuring (LDS) or bonding.

[0052] In this embodiment, by placing the antenna radiator on the hinge cover, the antenna radiator has a larger clearance area. Furthermore, the size of the hinge cover is larger than the size of any single fold of the electronic device, which facilitates the placement of antenna radiators with larger radiating surfaces and various forms, thereby improving the wireless communication performance of the electronic device.

[0053] In one exemplary embodiment, such as Figure 3 and Figure 4 As shown, this embodiment of the present disclosure provides an electronic device 100, which includes an antenna radiator 11 and a power supply unit 12. The antenna radiator 11 is disposed on a hinge cover 20 of the electronic device 100. When the two folded parts 30 are in the folded state, the hinge cover 20 is exposed between the two folded parts 30. The power supply unit 12 is used to supply power to the antenna radiator 11.

[0054] Among them, such as Figures 2 to 4 As shown, the hinge cover 20 includes a cover body 21 made of a conductive material, and at least one slit is provided in the cover body 21, which defines a portion of the cover body 21 to form an antenna radiator 11. The conductive material can be, for example, a metal, an alkali metal composite material, etc.

[0055] In some embodiments, the antenna device 10 includes a dipole antenna. For example... Figure 2 As shown, along the extending direction of the cover plate body 21 ( Figure 4 As shown in the x-direction, a first slit 22 is provided at the middle position of the cover plate body 21. The two parts of the cover plate body 21 located on both sides of the first slit 22 are electrically insulated, thereby forming two antenna radiators 11 of the dipole antenna. In this embodiment, by setting the first slit 22 at the middle position of the cover plate body 21, it is convenient to divide the cover plate body 21 into two symmetrical antenna radiators 11 (the length of each antenna radiator 11 is about 1 / 4 wavelength), so as to meet the setting requirements of the dipole antenna.

[0056] In some alternative implementations, see Figure 2 The first slit 22 is provided with an insulating filler structure 26, which is connected to the cover body 21 and flush with the surface of the cover body 21, thereby ensuring the appearance integrity of the pivot cover 20. The insulating filler structure 26 is made of materials such as plastic. In one example, the insulating filler structure 26 can be formed in the first slit 22 using a nano-injection molding process (see reference). Figure 4 ).

[0057] In some alternative embodiments (not shown in the figures), a sheath pin is provided at the end of each antenna radiator. By providing the sheath pin, the length of the antenna radiator can be adjusted (reduced), enabling the antenna radiator to radiate and receive antenna signals in a specified frequency band, or to enhance the antenna's radiation performance.

[0058] In other embodiments, the antenna device 10 includes an inverted-F antenna (IFA antenna). For example... Figure 3 and Figure 4 As shown, a second slit 23 is provided on the cover plate body 21, which divides the cover plate body 21 into a first segment 21a and a second segment 21b. The length of the first segment 21a is ( Figure 4 The length of the first segment 21a (in the x direction shown in the diagram) is greater than that of the second segment 21b. The first segment 21a constitutes the antenna radiator 11 of the IFA antenna. The first segment 21a is connected to the feed section 12 and grounded.

[0059] The second segment 21b of the cover plate body 21 can serve as a parasitic branch of the antenna device 10, forming a symmetrically coupled parasitic element structure. (See also...) Figure 3 and Figure 4The second segment 21b of the cover plate body 21 is coupled with the first segment 21a through the second gap 23 to generate energy interaction. Thus, the variable current in the first segment 21a can generate excitation in the second segment 21b, so that additional resonant modes are generated in the second segment 21b, or work together with the first segment 21a to adjust the resonant frequency of the first segment 21a, thereby increasing the coverage frequency band and radiation efficiency of the antenna device 10.

[0060] In some alternative implementations, see Figure 3 and Figure 4 An insulating filling structure 26 is provided within the second fracture 23. This has been explained in the foregoing embodiments and will not be repeated here.

[0061] In some other embodiments, the antenna device 10 includes a monopole antenna. For example... Figure 5 As shown, along the extending direction of the cover plate body 21 ( Figure 4 (as shown in the x direction), the cover plate body 21 is provided with a third slit 24 and a fourth slit 25 spaced apart, and the cover plate body 21 between the third slit 24 and the fourth slit 25 constitutes the antenna radiator 11 of the monopole antenna.

[0062] In some alternative implementations, see Figure 5 Insulating filling structures 26 are provided in the third fracture 24 and the fourth fracture 25 (see reference). Figure 4 As explained in the foregoing embodiments, it will not be repeated here.

[0063] In one exemplary embodiment, such as Figure 3 and Figure 4 As shown, this embodiment of the present disclosure provides an electronic device 100, which includes an antenna radiator 11 and a power supply unit 12. The antenna radiator 11 is disposed on a hinge cover 20 of the electronic device 100. When the two folded parts 30 are in the folded state, the hinge cover 20 is exposed between the two folded parts 30. The power supply unit 12 is used to supply power to the antenna radiator 11.

[0064] In this embodiment, the antenna device 10 of the electronic device 100 includes a slot antenna. For example... Figure 6 As shown, the hinge cover 20 is made of conductive material, and a slot 27 is provided on the hinge cover 20. The slot 27 constitutes the antenna radiator 11 of the slot antenna. The slot 27 with different geometric shapes can change the current path, electric field distribution and coupling mode, thereby affecting the operating frequency band, radiation characteristics and achievable functions of the slot antenna.

[0065] In one example, see Figure 6 The gap 27 is straight and extends in the same direction as the cover body 21. Figure 4The x-direction shown is the same. The straight-line slot 27 is suitable for narrowband communications (such as Bluetooth, Wi-Fi 2.4GHz), and its length is typically half or a quarter of the wavelength of the target frequency band.

[0066] In some alternative embodiments (not shown in the figures), the slot shape may also be H-shaped or annular. For example, an antenna device with an annular slot is suitable for ultra-wideband communications (such as radar).

[0067] In one exemplary embodiment, such as Figure 3 and Figure 4 As shown, this embodiment of the present disclosure provides an electronic device 100, which includes an antenna radiator 11 and a power supply unit 12. The antenna radiator 11 is disposed on the pivot cover 20 of the electronic device 100, and the power supply unit 12 is used to supply power to the antenna radiator 11.

[0068] In this embodiment, the hinge cover 20 of the electronic device 100 serves as the substrate of the antenna device 10, supporting the antenna radiator 11. The hinge cover 20 can be made of insulating material to avoid obstructing the antenna signal. Insulating materials such as composite fibers and ceramics are materials that combine mechanical strength and insulation.

[0069] In some embodiments, the antenna radiator 11 is disposed on the inner side of the pivot cover 20, that is, on the side of the pivot cover 20 facing the pivot. For example, the antenna radiator 11 can be disposed on the pivot cover 20 by laser direct molding, bonding or other methods.

[0070] In another embodiment, the antenna radiator 11 is embedded inside the hinge cover 20. For example, the antenna radiator 11 can be embedded in the hinge cover 20 using an injection molding process.

[0071] In this embodiment, the antenna radiator 11 can be formed as any one or more of a cavity antenna, a patch antenna, and an array antenna. By placing the antenna radiator 11 on the inner side of the hinge cover 20 or embedding it inside the hinge cover 20, the exposed surface of the hinge cover 20 will not be affected, which helps to ensure the structural strength and appearance of the hinge cover 20.

[0072] In one exemplary embodiment, such as Figure 3 and Figure 4 As shown, this embodiment of the present disclosure provides an electronic device 100, which includes an antenna radiator 11 and a power supply unit 12. The antenna radiator 11 is disposed on a hinge cover 20 of the electronic device 100. When the two folded parts 30 are in the folded state, the hinge cover 20 is exposed between the two folded parts 30. The power supply unit 12 is used to supply power to the antenna radiator 11.

[0073] The electronic device 100 provided in this embodiment may include various structures of the antenna device 10 provided in any of the foregoing embodiments.

[0074] Among them, such as Figure 4 As shown, the feed section 12 of the antenna device 10 includes a first circuit board, which transmits electrical energy and antenna signals from the electronic device 100 to the antenna radiator 11. In some embodiments, the first circuit board can be a rigid circuit board (e.g., a printed circuit board, or PCB for short), which is disposed opposite to the hinge cover 20, for example, between the inner side of the hinge cover 20 and the hinge. In other embodiments, the first circuit board may also be a flexible circuit board 121 of the electronic device 100 passing through the hinge, which is used to realize the electrical connection between the two folded portions 30. An extension 122 is provided on the flexible circuit board 121, which is disposed opposite to the hinge cover 20 and connected to the electrical connection portion 123.

[0075] Among them, such as Figure 4 As shown, the power supply section 12 also includes an electrical connection section 123, which connects the first circuit board and the power supply point 111 of the antenna radiator 11. The electrical connection section 123 is used to achieve a contact effect in a compact and narrow space, such as connecting the power supply point 111 and the return point 112 of the first circuit board and the antenna radiator 11 within the space between the hinge cover 20 and the hinge. In some embodiments, see... Figure 3 and Figure 4 Taking the IFA antenna in antenna device 10 as an example, the electrical connection part 123 includes a spring piece disposed between the first circuit board and the feed point 111. The elasticity of the spring piece can absorb and disperse external impacts to prevent damage to the antenna device 10. In some other embodiments (not shown in the figures), the electrical connection part includes a coaxial probe, which can be used to connect the antenna radiators together to form an electrical connection.

[0076] The power supply unit 12 includes a second circuit board (not shown in the figures), on which a radiating structure is disposed. The radiating structure is used to radiate electromagnetic signals, which are then coupled to the antenna radiator 11 for power supply. In one example, the antenna device 10 includes a slot antenna, and the radiating structure of the second circuit board is coupled through the slot 27 of the slot antenna.

[0077] In one example, see Figure 7The diagram illustrates the performance simulation of an IFA antenna. The horizontal axis represents frequency (GHz), and the vertical axis represents values ​​in dB. The orange curve represents S1.1, or reflection coefficient, showing the degree of signal reflection at different frequencies. A lower S1.1 value indicates better matching and less reflection. The green curve represents System Rad. Efficiency, which is the antenna's ability to convert input power into radiation. The blue curve represents System Total Efficiency, which takes into account all loss factors. Figure 7 It can be seen that when the electronic device provided in this embodiment has an IFA antenna on the hinge cover, the average B1 RX efficiency is -4.1dB, which exceeds the performance of conventional antennas.
