[0051] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.
[0052] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0053] Combination Figure 1 As shown, this embodiment provides a foldable electronic device, which includes: a first body module 1, a second body module 2, a hinge module 3, and an antenna assembly 4.
[0054] The first fuselage module 1 and the second fuselage module 2 are rotatably connected to the rotating shaft module 3, respectively.
[0055] The antenna assembly 4 includes a first radiating stub 41 and at least one second radiating stub 42; the first radiating stub 41 is located on the pivot module 3, and at least one second radiating stub 42 is located on at least one of the first fuselage module 1 and the second fuselage module 2; the extension directions of the first radiating stub 41 and the second radiating stub 42 are perpendicular, and the phase difference between the operating current in the first radiating stub 41 and the operating current in the second radiating stub 42 is 90 degrees.
[0056] In this embodiment of the foldable electronic device, the antenna assembly 4 consists of two parts. The first radiating branch 41 is located in the pivot module 3, which can make full use of the axial space within the pivot module 3. Moreover, the pivot module 3 is far from the electrical components in the two body modules, providing a better clearance environment. The second radiating branch 42 is located in the two body modules and can be arranged along the edge of the body module, so that the second radiating branch 42 and the first radiating branch 41 remain perpendicular. By controlling the phase difference of the operating current in the first radiating branch 41 and the second radiating branch 42 to be 90 degrees, the first radiating branch 41 and the second radiating branch 42 can form a circularly polarized antenna. Utilizing the advantages of this circularly polarized antenna in terms of stability and adaptability, the antenna assembly 4 can meet the performance requirements of satellite communication technology, thereby enabling satellite communication for the foldable electronic device.
[0057] For example, the number of second radiating branches 42 is one, two, three, etc. When the number of second radiating branches 42 is two or more, the second radiating branches 42 can be located on the first fuselage module 1 or on the second fuselage module 2, or a portion of the second radiating branches 42 can be located on the first fuselage module 1 and another portion on the second fuselage module 2.
[0058] A circularly polarized antenna is a special type of antenna in which the electric field vector of the transmitted or received electromagnetic wave traces a circular or elliptical trajectory. A circularly polarized antenna simultaneously carries two signals of equal amplitude and orthogonality (90 degrees out of phase). Through a specific structure and feeding method, these two signals are superimposed in space, thereby generating a circularly polarized wave.
[0059] In complex environments, such as urban canyons and indoor environments, signals undergo multiple reflections and refractions, causing changes in polarization direction. Circularly polarized antennas can receive signals with arbitrary polarization directions, reducing polarization mismatch losses and effectively improving the stability and reliability of signal reception.
[0060] Circularly polarized antennas radiate energy uniformly in different directions, providing a wide signal coverage range. They are suitable for scenarios requiring all-around coverage, such as satellite communication and mobile communication base stations.
[0061] Compared to linearly polarized antennas, circularly polarized antennas have lower requirements for the directivity of the receiving antenna, enhancing the flexibility and reliability of the system. In applications where precise antenna alignment is difficult, such as emergency rescue and military operations, this characteristic of circularly polarized antennas makes them perform exceptionally well.
[0062] Circularly polarized waves exhibit minimal attenuation under adverse weather conditions such as rain, fog, and snow, possess strong penetrating power into the ionosphere, and are unaffected by the Faraday effect generated by the Earth's polar magnetic fields. They have significant application value in fields such as satellite communications.
[0063] In some possible implementations, the first radiating stub 41 and the second radiating stub 42 in the antenna assembly 4 of this embodiment are two mutually perpendicular dipole antennas. By controlling the amplitude and phase of the two dipole feeds, they can generate circularly polarized radiation, which has a wide bandwidth and good radiation characteristics.
[0064] In other possible implementations, the folding methods of the first fuselage module 1 and the second fuselage module 2 include horizontal inward folding, horizontal outward folding, and vertical inward folding.
[0065] For example, the foldable electronic device also includes a flexible screen 5, which is bendable and foldable. The flexible screen 5 covers the first body module 1, the second body module 2, and the hinge module 3. Optionally, the flexible screen 5 is an organic light-emitting diode (OLED) display. OLED displays have advantages such as self-illumination, high contrast, fast response speed, and bendability, which can achieve better folding effect and display quality.
[0066] Combination Figure 2 and Figure 3 As shown, in some embodiments, the pivot module 3 includes a pivot body 32 and a pivot cover 31, the pivot cover 31 being made of insulating material; a first radiating branch 41 is located on the pivot cover 31.
[0067] With the above arrangement, the hinge cover 31 in the hinge module 3 is made of insulating material and has insulating properties. Furthermore, the hinge cover 31 is far away from the internal components of the foldable electronic device, providing better clearance conditions. Thus, the first radiating branch 41 is arranged on the hinge cover 31, resulting in better electromagnetic wave transmission and reception performance.
[0068] Exemplary examples include, but are not limited to, polyamide (also known as nylon), polycarbonate (PC), fiber glass (FG), polyethylene (PE), polyether, polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), polypropylene, polystyrene (PS), polyvinyl chloride (PVC), and so on. Any one or any combination of the above materials can be used to form this embodiment.
[0069] Combination Figure 2 and Figure 3 As shown, in some embodiments, the first radiating branch 41 is located on the surface of the pivot cover 31, or the first radiating branch 41 is located inside the pivot cover 31.
[0070] In this embodiment, the first radiating branch 41 can be arranged on the surface of the rotating cover 31 or inside the rotating cover 31, both of which can realize the transmission and reception of electromagnetic waves.
[0071] In some possible implementations, the first radiating branch 41 is an LDS antenna, i.e., an antenna fabricated using Laser Direct Structuring (LDS) technology. The movement of the laser can be controlled by a computer, projecting it onto a molded three-dimensional plastic device (e.g., the surface of the hinge cover 31) along the trajectory of a conductive pattern. This causes the organometallic composite in the plastic device to release metal particles, activating the circuit pattern in a short time. Then, through electroplating, a three-dimensional metal circuit is formed, thereby giving the plastic part electrical properties and realizing the antenna function.
[0072] Since the first radiating stub 41 is directly laser-etched onto the hinge cover 31, interference from internal components of the foldable electronic device is avoided, effectively ensuring the signal quality of the foldable electronic device and providing users with a more stable communication experience. It also enhances the utilization of internal space in the foldable electronic device, helping to achieve a thinner design and meeting consumer demand for lightweight foldable electronic devices, while also providing more space for the layout of other components. The first radiating stub 41 can be fabricated on various complex three-dimensional plastic devices according to different product shapes and design requirements of the hinge cover 31, without being limited by the shape and size of traditional antennas, thus better meeting the personalized design needs of products.
[0073] For example, the first radiating branch 41 is located on the surface of the pivot cover 31 facing the inside of the foldable electronic device.
[0074] In some possible implementations, the first radiating branch 41 is a metallic conductor and is embedded inside the pivot cover 31. In this embodiment, the pivot cover 31, made of insulating material, can be manufactured using injection molding, during which the first radiating branch 41 can be embedded.
[0075] Combination Figure 4 As shown, in some embodiments, the antenna assembly 4 further includes at least one feed line 43.
[0076] The first radiating branch 41 is provided with at least one first feed point 411, and each first feed point 411 is electrically connected to a feed line 43.
[0077] With the above arrangement, the antenna assembly 4 can be fed by electrically connecting the feed line 43 to the first feed point 411 on the first radiating branch 41.
[0078] For example, the number of feeder lines 43 may be one, two, three, etc., and correspondingly, the number of first feed points 411 may be one, two, three, etc. Optionally, each first feed point 411 is electrically connected to a feeder line 43.
[0079] In some possible implementations, one end of the feed line 43 is connected to the first feed point 411, and the other end extends into the first fuselage module 1 or the second fuselage module 2.
[0080] Combination Figure 5 As shown, in some embodiments, when the first radiating branch 41 is located inside the pivot cover 31, the surface of the pivot cover 31 is provided with at least one wiring gap 311, each wiring gap 311 is connected to a first power supply point 411, and the wiring gap 311 is used to insert the power supply wire 43, so that the power supply wire 43 is electrically connected to the first power supply point 411.
[0081] With the above arrangement, when the first radiating branch 41 is built inside the rotating cover 31, the first radiating branch 41 can be electrically connected to the feeder wire 43 by setting a wiring gap 311 on the surface of the rotating cover 31.
[0082] In some possible implementations, the feed line 43 and the first feed point 411 of the first radiating branch 41 within the wiring gap 311 can be reliably connected together by means of welding, crimping, etc.
[0083] For example, the feeder wire 43 is crimped to the first feed point 411. The gap of the first feed point 411 of the first radiating branch 41 is arranged in the wiring gap 311. There is an insertion gap between the first feed point 411 and the inner wall of one side of the wiring gap 311. The end of the feeder wire 43 is inserted into the insertion gap. The inner wall of the wiring gap 311 can apply pressure to the end of the feeder wire 43, so that the feeder wire 43 is crimped together with the first feed point 411.
[0084] In some possible implementations, the feed line 43 is made of a flexible printed circuit board (FPC). The feed line 43 has a linear conductive portion 431 and a block conductive portion 432. The block conductive portion 432 is located at the end of the feed line 43 corresponding to the first feed point 411. The linear conductive portion 431 is connected to the block conductive portion 432 and extends along the feed line 43 to the other end of the feed line 43, electrically connecting the block conductive portion 432 to the radio frequency circuit within the first housing module 1 or the second housing module 2. Exemplarily, both the linear conductive portion 431 and the block conductive portion 432 are formed on the feed line 43 using processes such as etching.
[0085] For example, there is an insertion gap between the first power supply point 411 and one side inner wall of the wiring gap 311. The end of the power supply wire 43 with the block-shaped conductive part 432 is inserted into the insertion gap. The block-shaped conductive part 432 is opposite to the first power supply point 411. The inner wall of the wiring gap 311 can apply pressure to the block-shaped conductive part 432, so that the block-shaped conductive part 432 is pressed together with the first power supply point 411.
[0086] Combination Figure 1 As shown, in some embodiments, the first fuselage module 1 includes a first side 101 and a second side 102. The first side 101 is connected to the pivot module 3, and the second side 102 is perpendicularly connected to the first side 101. The second radial branch 42 is located on the second side 102.
[0087] With the above arrangement, the second radiating branch 42 can be arranged on the first body module 1, and can be perpendicular to the first radiating branch 41 in the pivot module 3 regardless of whether the foldable electronic device is in the folded or unfolded state, thus achieving circular polarization characteristics.
[0088] Combination Figure 1 As shown, in some embodiments, the second fuselage module 2 includes a third side 201 and a fourth side 202, the third side 201 being connected to the pivot module 3, and the fourth side 202 being perpendicularly connected to the third side 201; the second radial branch 42 is located on the fourth side 202.
[0089] With the above arrangement, the second radiating branch 42 can be arranged on the second body module 2. Whether the foldable electronic device is in the folded state or the unfolded state, it can be perpendicular to the first radiating branch 41 in the pivot module 3 to achieve circular polarization characteristics.
[0090] Combination Figure 1As shown, in some embodiments, the first fuselage module 1 includes a first side 101 and a second side 102, the first side 101 being connected to the pivot module 3, and the second side 102 being perpendicularly connected to the first side 101; the second fuselage module 2 includes a third side 201 and a fourth side 202, the third side 201 being connected to the pivot module 3, and the fourth side 202 being perpendicularly connected to the third side 201. There are two second radiating branches 42, one of which is located on the second side 102, and the other is located on the fourth side 202.
[0091] With the above arrangement, a second radiating stub 42 can be arranged on the second side 102 and the fourth side 202 of the first fuselage module 1 and the second fuselage module 2, which are perpendicular to the pivot module 3. The two second radiating stubs 42 can be combined with the first radiating stub 41 to form two circularly polarized antennas. Moreover, since the two second radiating stubs 42 are arranged on the left and right sides of the pivot module 3, that is, the two second radiating stubs 42 are located on the left and right sides of the first radiating stub 41, one of the two circularly polarized antennas formed is a left-hand circularly polarized antenna, and the other is a right-hand circularly polarized antenna.
[0092] For example, antenna assembly 4 uses a left-hand circularly polarized antenna as the receiving antenna. This is because in the downlink of satellite communication, satellites typically use left-hand circularly polarized antennas to transmit signals to ground stations. The interaction between the left-hand circularly polarized wave and environmental factors such as the Earth's magnetic field during propagation allows it to better maintain signal stability and accuracy at the receiving end.
[0093] In another exemplary embodiment, antenna assembly 4 employs a right-hand circularly polarized antenna as the transmitting antenna. This is because in the uplink of satellite communication, ground equipment typically uses a right-hand circularly polarized antenna to transmit signals to the satellite. Furthermore, right-hand circularly polarized signals can penetrate obstacles better in certain wireless communication scenarios, such as in urban environments where their diffraction ability against obstacles like buildings is relatively strong, thereby expanding the signal coverage area.
[0094] In this case, left-hand circular polarization means that the horizontal polarization signal (i.e., the polarization signal corresponding to the left-hand second radiating branch 42) lags behind the vertical polarization signal (i.e., the polarization signal of the first radiating branch 41) by 90 degrees; right-hand circular polarization means that the horizontal polarization signal (i.e., the polarization signal corresponding to the right-hand second radiating branch 42) leads the vertical polarization signal (i.e., the polarization signal of the first radiating branch 41) by 90 degrees.
[0095] In this embodiment, the antenna assembly 4 utilizes the characteristic of mutual isolation between left-hand circular polarization and right-hand circular polarization to transmit two different signals simultaneously in the same frequency band, thereby doubling the satellite communication capacity.
[0096] Furthermore, when the foldable electronic device is in the folded state, the current directions of the two second radiating branches 42 are the same, which helps to improve the radiation performance of the antenna assembly 4 and enhance the wireless communication performance of the foldable electronic device in the folded state.
[0097] Combination Figure 1 As shown, in some embodiments, the first fuselage module 1 includes a first fuselage mid-frame 11, and the second fuselage module 2 includes a second fuselage mid-frame 21.
[0098] When the second radial branch 42 is located on the second side 102, the second radial branch 42 is located on the first fuselage mid-frame 11 corresponding to the second side 102; when the second radial branch 42 is located on the fourth side 202, the second radial branch 42 is located on the second fuselage mid-frame 21 corresponding to the fourth side 202.
[0099] With the above arrangement, the second radiating branch 42 can be integrated into the first fuselage mid-frame 11 and / or the second fuselage mid-frame 21, making full use of the middle of the mid-frame, increasing the effective area of the antenna, enabling better signal reception and transmission, maintaining good signal stability in complex environments, and reducing signal attenuation and interference.
[0100] Among some possible implementations, refer to Figure 1 As shown, a second feed point 423 is provided on the second radiating branch 42, and the second radiating branch 42 is arranged with a gap structure 424 between it and the first fuselage middle frame 11 or the second fuselage middle frame 21.
[0101] Combination Figure 1 and Figure 6 As shown, in some embodiments, when the second radiating branch 42 is located on the second side 102 and the fourth side 202 respectively, the second radiating branch 42 includes a second radiating branch one 421 and a second radiating branch two 422.
[0102] The length of the second radiating branch 421 is L1, and the length of the second radiating branch 422 is L2, where L1 ≠ L2.
[0103] With the above arrangement, the two second radiating stubs 42 have different lengths, so they can be combined with the first radiating stub 41 to form a left-hand circularly polarized antenna and a right-hand circularly polarized antenna, respectively.
[0104] For example, the second radiating stub 421 and the first radiating stub 41 form a left-hand circularly polarized antenna, and the second radiating stub 422 and the first radiating stub 41 form a right-hand circularly polarized antenna, wherein L1 is greater than L2.
[0105] Combination Figure 4 and Figure 6As shown, in some embodiments, the number of first feed points 411 of the first radiating branch 41 is two, and the two first feed points 411 are arranged at intervals along the axial direction of the rotating shaft module 3.
[0106] With the above arrangement, in order to meet the feeding requirements of the antenna assembly 4 having a left-hand circularly polarized antenna and a right-hand circularly polarized antenna, the number of first feeding points 411 is two, and according to the wavelength requirements of the left-hand circularly polarized antenna and the right-hand circularly polarized antenna, the two first feeding points 411 are arranged at intervals on the first radiating stub 41.
[0107] For example, the first feed point 411 includes a first feed point 4111 and a first feed point 4112. The vertical distance from the first feed point 4111 to the second radiating stub 422 is L3, and the vertical distance from the first feed point 4112 to the second radiating stub 422 is L4, wherein L3 is greater than L4.
[0108] In some embodiments, the antenna assembly 4, consisting of the first radiating stub 41 and the second radiating stub 42, is used to cover satellite communication frequency bands. These satellite communication frequency bands include the L-band (frequency range of 1.5-2.7 GHz), the S-band (frequency range of 2-4 GHz), and the C-band (its downlink frequency range is 3.7-4.2 GHz, and its uplink frequency range is 5.925-6.425 GHz).
[0109] It should be noted that, in this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
