[0057] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0058] Various modifications and variations can be made to this application without departing from its spirit or scope, which will be apparent to those skilled in the art. Therefore, this application is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the implementation methods provided in the embodiments of this application can be combined with each other without contradiction.

[0059] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] As described in the background section, improving the antenna performance of electronic devices while ensuring structural strength, heat dissipation efficiency, and aesthetic industrial design has become one of the core challenges in electronic device design.

[0061] This challenge manifests itself in the extremely limited freedom of antenna placement within electronic devices due to the stringent constraints of all-metal casings. An irreconcilable conflict exists between antenna radiation performance and the device's heat dissipation structure, aesthetics, and manufacturing costs. Designers must, within extremely limited space, ensure the antenna has a good "headroom" radiation environment to maintain a stable radiation pattern and efficiency, while avoiding excessive negative impacts on heat dissipation channels, product appearance, and assembly costs. Current industry solutions each have their own focus, but none have perfectly balanced these mutually constraining requirements.

[0062] Currently, antenna design solutions for all-metal casings in the industry mainly fall into two categories. The first type involves placing the antenna unit directly in the air intake and exhaust area of ​​the device's cooling system, utilizing the inherent perforation structure of this area to achieve electromagnetic wave radiation. The second type is more commonly found in clamshell devices such as laptops, where the antenna is constructed by creating coordinated slots on the base and screen sides. Specifically, a T-shaped slot is often created on the side of the base's back cover, with corresponding windows on the top cover of the base or the back cover of the screen, thus forming an H-shaped slotted antenna spanning multiple structural components. Signal overflow is achieved through these multiple "shell breaks."

[0063] However, all of the aforementioned existing design solutions have significant drawbacks. For the first type, utilizing heat dissipation vents, the complex structures such as metal grilles, support ribs, filters, or inclined guide plates at the vents reflect and scatter electromagnetic waves, severely disrupting the "clearance" environment upon which the antenna relies for operation. This leads to distortion of the antenna radiation pattern, creating signal "dead zones" or "abnormal sidelobes," making the wireless connection extremely unstable in specific directions. Simultaneously, because the antenna design occupies part of the heat dissipation vent space, the opening ratio in that area cannot reach 100%, directly limiting the effective ventilation area and airflow efficiency of the air duct, adversely affecting the equipment's heat dissipation performance. For the second type, the H-shaped slotted antenna with multi-faceted slots, precise slotting is required on multiple metal housing components, filled with plastic parts. This not only significantly disrupts the product's integrated metal appearance, imposing stringent limitations on industrial design, but also significantly increases mold complexity, assembly difficulty, and material costs, reducing the product's market competitiveness.

[0064] In summary, existing all-metal hull antenna designs struggle to achieve an ideal balance between electrical performance, heat dissipation efficiency, aesthetics, and manufacturing costs. An innovative design approach or structural solution is urgently needed to effectively address this multi-objective optimization challenge.

[0065] In view of this, embodiments of this application provide an electronic device, such as... Figure 1 As shown, the electronic device includes:

[0066] The equipment body includes a receiving space enclosed by a metal shell 10;

[0067] A first component structure 20 is disposed within the accommodating space, and the first component structure 20 cooperates with the metal housing 10 to form a resonant cavity within the accommodating space;

[0068] The antenna module disposed in the resonant cavity includes an antenna radiator 30, which is capable of signal coupling with the metal housing 10 forming the resonant cavity.

[0069] It should be noted that, in this embodiment, a slit 40 is provided on the metal housing 10 forming the resonant cavity. Part of the radiation signal generated by the antenna radiator 30 is directly radiated outward to the receiving space through the slit 40, and another part is radiated outward to the receiving space through the slit 40 after electromagnetic resonance is excited in the resonant cavity.

[0070] Optionally, in one embodiment of this application, the device body can be the main unit of a laptop computer, a metal chassis, a drone, a mobile phone, a tablet, etc. This application does not limit the specific type of device; it depends on the circumstances. The following description uses the main unit of a laptop computer as an example to illustrate the electronic device provided in the embodiments of this application.

[0071] Optionally, in one embodiment of this application, the antenna radiator may be an IFA antenna radiator, a loop antenna radiator, or other types of antenna radiators. This application does not limit this and the choice depends on the specific circumstances.

[0072] Optionally, in one embodiment of this application, the resonant cavity can be a rectangular resonant cavity, but this application does not limit it. In other embodiments of this application, the resonant cavity can also be a resonant cavity of other shapes, depending on the specific circumstances.

[0073] In the electronic device provided in this application embodiment, a portion of the signal generated by the antenna radiator is directly radiated outwards from the receiving space through the gap, while another portion is radiated outwards from the receiving space through the gap after electromagnetic resonance is excited within the resonant cavity. The portion of the signal generated by the antenna radiator that radiates outwards from the receiving space through the gap after electromagnetic resonance is excited within the resonant cavity has strong directionality, thereby reducing the probability of signal "dead zones" or "sidelobe anomalies" and improving the antenna performance of the electronic device. This solution can also be used in subsequent millimeter-wave communication devices.

[0074] Furthermore, in the electronic device provided in this application embodiment, only one slit is opened on the metal shell forming the resonant cavity. Whether the signal generated by the antenna radiator is radiated directly to the outside of the receiving space through the slit, or radiated to the outside of the receiving space through the slit after electromagnetic resonance is excited in the resonant cavity, it is radiated to the outside of the receiving space through the same slit. This reduces the number of slits opened on the metal shell of the electronic device, does not damage the integrated metal appearance of the product, is beneficial to the ID design of the electronic device, and can also reduce the mold complexity, assembly difficulty and material cost in the shell manufacturing process of the electronic device, thereby improving the market competitiveness of the product.

[0075] Furthermore, since metal casings have good thermal conductivity, the electronic device provided in this application embodiment has its main body casing formed by a metal casing, which can improve the heat dissipation performance of the electronic device.

[0076] Furthermore, in the electronic device provided in this application embodiment, the antenna module is disposed in the resonant cavity formed by the first component structure and the metal shell in the accommodating space, rather than near the heat dissipation vent of the electronic device. This avoids the mutual interference between the antenna module and the heat dissipation components, thereby further improving the antenna performance and heat dissipation performance of the electronic device.

Taking the device body as the main unit of a laptop computer as an example, one of the first housing 11 and the second housing 12 is a D-shell and the other is a C-shell. The third housing 13 can be the housing portion in the device body that connects the C-shell and the D-shell.

[0078] Based on the above embodiments, in one embodiment of this application, the first component structure 20 is disposed between the first housing 11 and the second housing 12, and connected to the first housing 11 and the second housing 12, so as to be directly electrically connected to the metal housing 10 through the first component structure 20, so that the first component structure 20, the first housing 11, the second housing 12 and the third housing 13 enclose a closed resonant cavity; in another embodiment of this application, the first component structure 20 is connected to the first housing 11 and / or the second housing 12 through a conductor structure, so as to enclose a closed resonant cavity with the first housing 11, the second housing 12 and the third housing 13.

[0080] Based on any of the above embodiments, in one embodiment of this application, the following continues... Figure 1As shown, the gap 40 is a first gap provided in the first housing 11. The first gap extends along a first direction, which is the direction of the long side or the short side of the first housing 11. The metal housing 10 forming the resonant cavity can transmit the radiation signal generated by the antenna radiator 30 to the first gap in the form of a feed current or a reflected wave, so as to radiate wireless signals to the outside of the containing space using the first gap.

[0081] Specifically, in one embodiment of this application, the radiation signal generated by the antenna radiator 30 is coupled to the first housing 11, the second housing 12 or the third housing 13 and transmitted to the opening of the slot 40 on the first housing 11 in the manner of a feed current, and radiates outward from the accommodating space through the first slot on the first housing 11.

[0082] In another embodiment of this application, the radiation signal generated by the antenna radiator 30 is coupled to the first housing 11, the second housing 12, the third housing 13 or the first component structure 20, and is reflected. It is then radiated twice or multiple times in the resonant cavity formed by the first component structure 20 and the metal housing 10 in the accommodating space, and finally transmitted to the opening of the slot 40 on the first housing 11, and radiated outward from the accommodating space through the first slot on the first housing 11.

[0083] In another embodiment of this application, the gap is a second gap disposed on the third housing, the second gap extending along the long side of the third housing, the metal housing forming the resonant cavity can transmit the radiation signal generated by the antenna radiator to the second gap in the form of a feed current or a reflected wave, so as to radiate wireless signals to the outside of the accommodating space using the second gap.

[0084] Specifically, in one embodiment of this application, the radiation signal generated by the antenna radiator is coupled to the first housing, the second housing, or the third housing and transmitted to the slot opening on the third housing in the form of a feed current, and then radiated outward from the receiving space through the second slot on the third housing.

[0085] In another embodiment of this application, the radiation signal generated by the antenna radiator is coupled to the first housing, the second housing, the third housing or the first component structure, reflected, and radiated twice or multiple times in the resonant cavity formed by the first component structure and the metal housing in the accommodating space. Finally, it is transmitted to the gap opening on the third housing and radiated outward from the accommodating space through the second gap on the third housing.

[0086] Based on any of the above embodiments, in one embodiment of this application, the first component structure is a conductive structure, so that the electronic device can use the first component structure and the metal housing to form a resonant cavity within the accommodating space to shield the radio frequency signals generated by the components located inside the accommodating space and outside the resonant cavity, thereby shielding the impact of the radio frequency signals on the antenna performance of the antenna module and improving the antenna performance of the electronic device. However, this application does not limit this, and it depends on the specific circumstances.

[0087] Optionally, in one embodiment of this application, such as Figure 2 As shown, the first component structure 20 is a support structure for supporting the antenna radiator 30. In this embodiment, the antenna radiator 30 is disposed at the first end of the support structure facing the third housing 13, and the second end of the support structure away from the first end is electrically connected to the first housing 11 and / or the second housing 12 through a conductor structure 60. In this embodiment, the conductor structure 60 can be conductive foam, a copper layer laid on the first side of the support structure, or a conductor structure formed on the support structure by LDS process. This application does not limit this, and it depends on the specific situation. It should be noted that LDS, short for Laser Direct Structuring, is an advanced electronic device manufacturing process that allows for the direct formation of a precise conductive layer on complex three-dimensional plastic parts through laser engraving and chemical plating.

[0088] Specifically, in one embodiment of this application, the following continues... Figure 2 As shown, the antenna radiator 30 includes a first radiating branch 31, which is the radiating part of the antenna radiator 30 near the second housing 12. In this embodiment, the first radiating branch 31 of the antenna radiator 30 is connected to the second housing 12, which serves as the antenna ground of the antenna module, through a conductive element 50, so as to realize the electrical connection of the grounding point of the antenna radiator 30.

The braided layer of the feed line is electrically connected to the second housing, which serves as the antenna ground of the antenna module.

[0090] Optionally, in one embodiment of this application, the bracket structure can be fixed to the second housing with screws, but this application does not limit this and it depends on the specific circumstances.

[0091] Based on any of the above embodiments, in one embodiment of this application, the following continues... Figure 1 As shown, the electronic device further includes a speaker module 70 disposed within the accommodating space, and the first gap is also used to output the sound signal generated by the speaker module 70. In this embodiment, the first component structure 20 is an auxiliary support structure disposed at the third end of the speaker module 70 away from the third housing 13, and the antenna radiator 30 is disposed at the fourth end of the speaker module 70 near the third housing 13.

In this embodiment, the auxiliary support structure directly serves as a retaining wall to form a resonant cavity with the metal housing. In another embodiment of this application, the branches of the auxiliary support structure are connected to the first housing and / or the second housing through a conductor structure. In this embodiment, the conductor structure serves as a retaining wall to form a resonant cavity with the metal housing, or the auxiliary support structure and the conductor structure cooperate to serve as a retaining wall to form a resonant cavity with the metal housing, depending on the relative positions of the conductor structure and the auxiliary support structure. For example, if the conductor structure is connected to the first housing at one end and to the second housing at the other end, and completely fills the gap between the first and second housings in the direction from the first housing to the second housing, then the conductor structure acts as a barrier to form a resonant cavity with the metal housing; if the conductor structure is connected to either the first or second housing at one end and not to either the first or second housing at the other end, and does not completely fill the gap between the first and second housings in the direction from the first housing to the second housing, then in this embodiment, the auxiliary support structure and the conductor structure cooperate to form a resonant cavity with the metal housing as a barrier.

Specifically, in one embodiment of this application, the second radiating branch 32 is disposed on the first surface of the antenna support of the antenna module facing the third housing 13, the first radiating branch 31 is disposed on the second surface of the antenna support of the antenna module facing the second housing 12, and the third radiating branch 33 is disposed on the third surface of the antenna support of the antenna module facing the first housing 11. In another embodiment of this application, the second radiating branch 32 is disposed on the first surface of the speaker module located in the resonant cavity facing the third housing 13; the first radiating branch 31 is disposed on the second surface of the speaker module located in the resonant cavity facing the second housing 12, and the third radiating branch 33 is disposed on the third surface of the speaker module located in the resonant cavity facing the first housing 11.

[0105] Based on the above embodiments, in one embodiment of this application, the following continues... Figure 1 As shown, the third radiating branch 22 is directly opposite the gap 40 on the first housing, and the minimum distance d between the third radiating branch 22 and the gap 40 is less than or equal to 1 mm, so that the radiation signal generated by the third radiating branch 33 can be coupled to the first housing 11, transmitted through the first housing 11 to the gap 40, and transmitted out of the accommodating space through the gap 40, thereby enhancing the radiation efficiency of the antenna module and expanding the bandwidth of the antenna module.

[0106] Optionally, in one embodiment of this application, such as Figure 3As shown, the antenna radiator 30 further includes a fourth radiating branch 34 located between the first radiating branch 31 and the second radiating branch 32. The fourth radiating branch 34 is disposed on the second side of the antenna support of the antenna module or the speaker module located in the resonant cavity facing the second housing 12. That is, the fourth radiating branch 34 and the first radiating branch 31 are disposed on the same side of the antenna support of the antenna module or the speaker module located in the resonant cavity facing the second housing. In this embodiment, the fourth radiating branch does not overlap with the conductive element 50, and the distance between the fourth radiating branch and the second housing 12 is less than or equal to 2 mm, so that the radiated signal generated on the fourth radiating branch 34 can be coupled to the second housing 12 and transmitted through the metal housing 20 to the first gap on the first housing 11 in the manner of feeding current, thereby radiating outward from the receiving space using the first gap.

[0107] Based on any of the above embodiments, in one embodiment of this application, the radiation signal generated on the second radiating branch 32 is transmitted to the third housing 13 as a reflected wave, and then transmitted to the first gap on the first housing 11 as a feed current, so as to radiate a wireless signal outside the accommodating space using the first gap. In this embodiment, the electronic device does not limit the gap between the second radiating branch 32 and the third housing 13.

[0108] In another embodiment of this application, the radiated signal generated on the second radiating branch 32 is partially transmitted to the third housing 13 as a reflected wave, and then transmitted to the first gap on the first housing 11 as a feed current, so as to radiate a wireless signal outside the receiving space through the first gap. Part of the signal is directly coupled to the third housing 13 and transmitted to the first gap on the first housing 11 as a feed current, so as to radiate a wireless signal outside the receiving space through the first gap. In this embodiment, the gap between the second radiating branch 32 and the third housing 13 is less than or equal to 2 mm, so that the radiated signal generated on the second radiating branch 32 can be coupled to the third housing 13.

[0109] In summary, in the electronic device provided by the embodiments of this application, the radiation signal generated by the antenna radiator can be partially radiated directly to the outside of the accommodating space through the gap, partially radiated to the outside of the accommodating space after electromagnetic resonance is excited in the resonant cavity, partially coupled to the second housing and then transmitted to the gap for outward transmission through the gap, and partially coupled to the third housing and transmitted to the gap for outward transmission through the gap, thereby forming multiple resonant frequencies and expanding the bandwidth of the antenna module.

[0110] Optionally, if the speaker module includes a metal component, the antenna radiator can also achieve signal coupling with the metal component in the speaker module, so that the radiated signal generated by the antenna radiator is partially coupled to the metal component in the speaker module, and then radiated outwards from the receiving space through the gap, further extending the bandwidth of the antenna module. This application does not limit this, and it depends on the specific circumstances.

[0111] Based on any of the above embodiments, in one embodiment of this application, at least one sixth radiating branch may be provided on the inner surface of the support structure. The sixth radiating branch located on the inner surface of the support structure can be electrically connected to the portion of the antenna radiator located on the outer surface of the support structure through a through hole that penetrates from the inner surface to the outer surface of the support structure, thereby providing more freedom for the design of the antenna radiator. However, this application does not limit this and it depends on the specific circumstances.

[0112] Based on any of the above embodiments, in one embodiment of this application, such as Figure 4 As shown, the length S of the gap 40 is no greater than 4mm to ensure the antenna radiation performance of the gap, but this application does not limit this and it depends on the specific situation.

[0113] Based on any of the above embodiments, in one embodiment of this application, the structural parameters of the resonant cavity enable the antenna module of the electronic device to have an actual radiation efficiency of over 30% in the 2400-2500MHz, 5150-5850MHz, and 5925-7125MHz frequency bands.

[0114] It should be noted that the structural parameters of the resonant cavity can affect the frequency band and antenna performance of the antenna module of the electronic device.

[0115] Specifically, the electromagnetic waves excited by the radiation signal generated by the antenna radiator within the resonant cavity are reflected between the cavity walls to form standing waves. These standing waves are stable only at a specific resonant frequency (i.e., the resonant frequency), which can be expressed by the formula... (1) Calculated. Where c represents the speed of light, and The electrical constant and magnetic permeability of the medium are characterized respectively, such as Figure 5 As shown, L (perpendicular to the plane of the paper, not shown in the figure), W, and H represent the length, width, and height of the resonant cavity, respectively, and m, n, and p are integers representing the number of modes along the three directions.

[0116] Since the medium inside the resonant cavity is generally air, Formula (1) can be simplified to:

[0117] (2).

[0118] It should be noted that in this embodiment, m, n, and p, as mode parameters, directly determine the electromagnetic field distribution pattern within the resonant cavity, and their values ​​are positively correlated with the resonant frequency generated by the resonant cavity. Taking a rectangular resonant cavity as an example, m, n, and p represent the standing wave distribution pattern of the electromagnetic field in the length (L), width (W), and height (H) directions of the rectangular resonant cavity, respectively, i.e., the number of half-wavelengths along each direction. Specifically, m represents the number of half-wavelengths along the length L direction of the resonant cavity, n represents the number of half-wavelengths along the width W direction of the resonant cavity, and p represents the number of half-wavelengths along the height H direction of the resonant cavity.

[0119] In the transverse electric mode (TE mode), the electric field has no longitudinal component; typically, one parameter is 0, and the others are ≥1. For example, in TEmnp, if p=0, it means there is no electric field component along the height direction of the resonant cavity.

[0120] For transverse magnetic modes (TM modes), the magnetic field has no longitudinal component, and all three parameters are generally ≥1. For example, the TE100 mode has a half-wavelength distribution along the length of the resonant cavity, while remaining unchanged along the width and height of the resonant cavity; the TM111 mode has a half-wavelength field distribution along the length, width, and height of the resonant cavity.

[0121] Therefore, in practical applications, the directivity of the antenna pattern can be improved by adjusting the size of the resonant cavity, the position of the slot, and the routing of the antenna radiator to optimize the excitation of specific modes.

[0122] Compared to a single-slot antenna, a portion of the radiated signal generated by the antenna radiator is excited by electromagnetic resonance within the resonant cavity and then radiated outwards through the slot into the containing space. This allows for more effective optimization and control of the antenna module's radiation directional characteristics. Furthermore, by finely adjusting key parameters such as the wiring layout of the antenna radiator within the resonant cavity, the physical dimensions of the resonant cavity, and the position of the slot on the metal casing, the distribution pattern of the electromagnetic field within the resonant cavity can be actively controlled. This alters the excitation characteristics and spatial arrangement of the equivalent radiation source at the slot, ultimately achieving directional optimization and performance improvement of the antenna module's radiation pattern.

[0123] For example, when implementing a Wi-Fi antenna with a center frequency of 5 GHz, since the wavelength corresponding to the resonant frequency of the antenna module in free space satisfies If a higher-order mode (such as TE) is used 201 (m=2, n=0, p=1), increasing the mode contribution in the L direction, then based on formula (2), we can obtain: (3). In this embodiment, assuming H=10mm, we can solve for L≈35mm. At this time, the size of the resonant cavity is 35mm×5mm×10mm, which can meet the resonant frequency requirement.

[0124] Therefore, the electronic device provided in this application embodiment can adjust the resonant frequency of the antenna module by setting the structural parameters of the resonant cavity. Thus, the electronic device provided in this application embodiment can achieve full frequency band coverage for its antenna module, including the 2400-2500MHz, 5150-5850MHz, and 5925-7125MHz bands, by setting the structural parameters of the resonant cavity. It should be noted that in actual debugging, simulation tools such as HFSS can be used in conjunction with physical testing to optimize the gap size and antenna radiator layout, ultimately achieving full target frequency band performance coverage for the antenna.

[0125] To achieve better antenna performance and a more optimized antenna pattern, the gap length can be set based on the target frequency band when adjusting the antenna performance of electrical equipment. Taking the antenna module covering the entire frequency band of the WIFI antenna as an example, the 2.4G, 5G, 6G, and 7G frequencies covered by the WIFI antenna are respectively represented as... Since the resonant frequency of a half-wave dipole slot antenna can approximately satisfy: (4), where f is the resonant frequency, c is the speed of light, and S is the path length for different resonances. is the relative permittivity. Therefore, when the resonant frequency f is known, the initial value of S can be obtained according to this formula (4).

[0126] It should be noted that in this embodiment, for the low frequency (f1) of WIFI, its resonant frequency is affected by the size of the gap in the metal shell on the one hand, and by the synchronization effect of the low-order modes of the electromagnetic waves formed in the resonant cavity to expand the bandwidth and enhance radiation, i.e., a composite structure of "slot antenna + resonant cavity antenna" is adopted; specifically, in this embodiment, the length S of the gap in the metal shell approximately satisfies ;

[0127] For the mid-to-high frequencies (f2, f3, f4) of Wi-Fi, the resonance is contributed by the following three parts: first, it is generated by at least a portion of the antenna radiator itself; second, the higher-order modes of electromagnetic waves formed within the resonant cavity extend the antenna bandwidth; and third, the portion of the antenna radiator used to generate the mid-to-high frequencies of Wi-Fi also couples with the gaps in the metal casing, further enhancing the bandwidth and antenna performance. Specifically, in this embodiment, as... Figure 6 As shown, the length S of the gap on the metal casing approximately satisfies , , The connection point between the corresponding parts of S1 and S2 is the grounding point.

[0128] Therefore, the electronic device provided in this application embodiment can be debugged based on the actual environment. By setting the size of the gap on the metal shell and the structural parameters of the resonant cavity, the full coverage of the target frequency band and the performance optimization can be achieved.

[0129] Therefore, based on any of the above embodiments, in one embodiment of this application, the electronic device further includes an adjustment structure disposed within the accommodating space for adjusting the parameters of the resonant cavity and / or the slot structure. The adjustment structure can change the operating frequency of the antenna module by adjusting the structural parameters, thereby enabling the electronic device to change the operating frequency of the antenna module by adjusting the structural parameters through the adjustment structure according to actual usage requirements, thereby improving the antenna performance of the antenna module.

[0130] Based on any of the above embodiments, in one embodiment of this application, a fifth radiating branch is further provided on the side of the first housing facing the second housing. The fifth radiating branch is electrically connected to the first housing, and at least a portion of the fifth radiating branch is located at the position of the gap. In this embodiment, when the antenna module is in the working state, the fifth radiating branch and the gap together serve as radiating branches of the antenna module to transmit and receive wireless signals, thereby increasing the number of resonant frequencies of the antenna module and widening the bandwidth of the antenna module.

[0131] It should be noted that, in this embodiment, the first housing may have one, two, or more fifth radiating stubs on the side facing the second housing. Each additional fifth radiating stub on the side facing the second housing increases the resonant frequency of the antenna module and widens the bandwidth of the antenna module.

[0132] Based on any of the above embodiments, in one embodiment of this application, such as Figure 7 As shown, the device body includes a first body 100 and a second body 200 rotatably connected, and the antenna module and the first component structure are disposed within the accommodating space formed by the second body 200. Specifically, in this embodiment, the first body 100 includes a display portion composed of a fourth housing and a display screen, and the second body 200 includes a host portion composed of a first housing, a second housing, a third housing, and an input device, such as a laptop computer. Optionally, in this embodiment, the input device includes a keyboard and / or a touchpad to enable input to the electronic device using the keyboard and / or touchpad.

[0133] Based on the above embodiments, in one embodiment of this application, the electronic device includes two sets of antenna modules and a first component structure. The two sets of antenna modules and the first component structure are respectively disposed on both sides of the keyboard or the touchpad in a second direction to improve the antenna performance of the electronic device. The second direction is the long side direction of the second body. In this embodiment, as... Figure 8 As shown, the gap 40 on the metal casing is provided in a portion of the two opposite edges of the first casing 11 along the second direction.

[0134] In another embodiment of this application, the two sets of antenna modules and the first component structure are spaced apart at a first edge of the second body, the first edge being the edge of the second body away from the connection point with the first body. In this embodiment, as... Figure 9 As shown, the gap 40 is provided on the first edge of the first housing 11 in the second body 200.

[0135] It should be noted that in this embodiment, no gaps are opened on the second and third shells of the second body, so that the number of gaps opened on the metal shell of the electronic device is reduced, which will not damage the integrated metal appearance of the product, which is beneficial to the ID design of the electronic device. It can also reduce the mold complexity, assembly difficulty and material cost in the manufacturing process of the electronic device shell, and improve the market competitiveness of the product.

[0136] Optionally, in one embodiment of this application, the electronic device further includes a speaker module disposed within the accommodating space. The speaker module further includes a metal dustproof mesh disposed corresponding to the first gap on the first housing, so as to prevent dust from outside the accommodating space from entering the interior of the resonant cavity through the first gap and affecting the performance of the speaker module. It should be noted that, in this embodiment, the metal dustproof mesh can also work with the gap as a radiating stub of the antenna module to transmit and receive wireless signals. That is, the metal dustproof mesh serves as a radiating stub or adjustable stub connected to the gap, working together with the gap as a radiating stub to transmit and receive wireless signals, further improving the antenna performance of the electronic device. However, this application does not limit this, and it depends on the specific circumstances.

[0137] Based on any of the above embodiments, in one embodiment of this application, the adjustment structure built into the electronic device can also adjust the structural parameters of the resonant cavity and / or the gap according to the device form of the electronic device. For example, the performance of the antenna module when the electronic device is in the open state and the structural parameters of the resonant cavity and / or the gap are different when the electronic device is in the closed state, so that the antenna performance of the antenna module remains at its best regardless of the device form of the electronic device.

[0138] Furthermore, if the electronic device is in the open state, and the angle between the first body and the second body is different, the structural parameters of the resonant cavity and / or the gap will also be different, so as to further improve the antenna performance of the antenna module.

[0139] Optionally, in one embodiment of this application, the device form includes a laptop form, a book form, a tablet form, a tent form, etc., and this application does not limit this; it depends on the specific circumstances.

[0140] When the device body is in laptop form, the B side of the first body and the C side of the second body are usually opened at an angle greater than 90 degrees (such as 100-120 degrees), forming a shape similar to "L" or "V". This can be applied to scenarios that require a lot of typing, programming, document processing, and precise interaction between the keyboard and touchpad.

[0141] When the device body is in book form, the first body and the second body are 180 degrees apart and are located in the same plane, so that the display content of the screen can be completely laid flat to be viewed by the person opposite. It can be used in small spaces or used with a stylus as a slightly angled drawing board.

[0142] When the device body is in tablet form, the first body and the second body can be folded together via a 360-degree hinge, allowing the second body to be folded onto the A-side of the first body and placed close together. In this state, the electronic device looks and operates like a large tablet computer, making it suitable for content consumption and touch-first scenarios, such as reading e-books, browsing web pages, watching videos, playing touch games, taking handwritten notes, or drawing.

[0143] When the device body is in tent form, the electronic device is set up like a tent. Typically, by flipping the second housing more than 180 degrees (about 245 degrees), the D-shell of the second housing and the A-shell of the first body form an inverted "V" shape, which can be used to watch videos in places with limited space, such as kitchens, bedside tables, and airplanes.

[0144] The electronic device provided in the embodiments of this application will now be described in conjunction with specific examples.

[0145] In one specific embodiment of this application, the electronic device is provided with two sets of antenna modules. The dimensions of the resonant cavity are 63mm × 20mm × 6.5mm, that is, the length of the resonant cavity is 63mm, the width is 20mm, and the height is 6.5mm; the dimensions of the gap on the metal shell are 65mm × 3.5mm, that is, the length of the gap is 65mm and the width is 3.5mm. When the performance of the antenna module is tested, the results are as follows: Figures 10-12 ,in, Figure 10 This is a schematic diagram of the S11 curve of the main antenna in the two antenna modules. Figure 11 This is a schematic diagram of the S11 curve of the sub-antenna in the two antenna modules. Figure 12 This diagram illustrates the antenna radiation efficiency of the electronic device when it is in an open state (e.g., the angle between surface B of the first body and surface C of the second body is 110°). Curve a is the baseline of -5 dB, and curve b is the antenna radiation efficiency curve of the electronic device.

[0146] from Figure 10 As can be seen from the data, the return loss of the main antenna in both antenna modules is greater than 5dB in 2.4G, 5G, 6G, and 7G (i.e., S11 < -5dB), which means that the main antenna has good circuit transmission characteristics in the entire WIFI frequency band and has good antenna performance.

[0147] from Figure 11 It can be seen that the return loss of the secondary antenna in both antenna modules is greater than 5dB in 2.4G, 5G, 6G and 7G (i.e. S11 < -5dB), which means that the secondary antenna has good circuit transmission characteristics in the entire WIFI frequency band and has good antenna performance.

[0148] from Figure 12 It can be seen that when the electronic device is in the open state (e.g., the angle between the B side of the first body and the C side of the second body is 110°), the WIFI antenna radiation efficiency of the electronic device is ≥-5 dB in 2400-2500MHz, ≥-5 dB in 5150-5850MHz, and ≥-5 dB in 5925-7125MHz. The antenna has good spatial radiation performance, and the efficiency is ≥30% in the entire frequency band.

[0149] like Figure 13 As shown, Figure 13 A schematic diagram shows a structure for constructing an antenna by creating a slot in the foot pad at the base of the device. The antenna location K3 is a non-metallic area, while housings K1 and K2 are metal housings. The antenna opening K is located on housing K1. It should be noted that... Figure 13The structure shown differs from the electronic device provided in the embodiments of this application in terms of structure, signal radiation method, grounding method, signal feeding method, and energy distribution. Specifically,

[0150] In terms of structure, Figure 13 In the structure shown, there is no additional metal barrier on the surface of the antenna radiator, the antenna environment is relatively good, the structure is relatively "open" and there is no obvious rectangular cavity structure; while the electronic device provided in this application embodiment forms a rectangular cavity through the first component structure, the first housing (D housing), the second housing (C housing) and the third housing (side wall), and the rectangular cavity has gaps, the structure is more complex, more "closed" and has a specific cavity;

[0151] Regarding signal radiation, Figure 13 In the structure shown, the antenna radiator may rely on a portion of the metal shell K1 (the metal portion surrounding the non-metallic area of ​​the antenna location), or a structure related to the non-metallic area as the radiator. The overall radiator shape is affected by the "open" structure and is relatively dispersed. In contrast, in the electronic device provided in the embodiments of this application, the antenna module radiates energy using a resonant mode combining a slot and a resonant cavity.

[0152] Regarding grounding methods, Figure 13 In the structure shown, the antenna module grounding relies on the overall structure of the metal housing K2, with "metal housing K2 (C-shell) + surrounding metal boundary" as the grounding reference, and the radiation structure of the non-metallic area is grounded through the surrounding metal; while in the electronic device provided in the embodiments of this application, the antenna module grounding can be achieved through the second housing (C-shell) and the third housing (side wall), one side of the rectangular resonant cavity (the second housing) directly serves as the grounding terminal, and the first component structure is also connected to the grounding structure (the second housing) to form the grounding boundary of the cavity;

[0153] Regarding the feeding method, Figure 13 In the structures shown, the power supply is mostly a direct excitation of the radiation structure of the non-metallic region + metal edge by the coaxial line / PCB trace, which belongs to the near-field direct feeding; while in the electronic device provided by the embodiments of this application, the power supply is indirectly fed in by "exciting the long gap of the first housing (D Cover)" and "injecting energy into the rectangular resonant cavity", utilizing the resonant mode of the cavity (such as TE / TM mode), which relies more on the resonant radiation characteristics of the cavity;

[0154] In terms of energy distribution, Figure 13In the structure shown, the energy is distributed in the "open" structural space, which is relatively dispersed. Affected by the non-metallic area and the window, the energy is easy to diffuse into the surrounding space. However, in the electronic device provided in the embodiment of this application, the energy is distributed in the "long strip gap of the first shell" and "inside the rectangular resonant cavity". The energy is confined in the cavity through cavity resonance and then radiated directionally through the gap. The energy is more "concentrated" in the resonant region of the cavity and the gap.

[0155] Regarding antenna design principles, Figure 13 The structure shown is based on an "open" metal-nonmetal composite structure, utilizing the radiation characteristics of the metal part. The principle is more inclined towards the traditional metal radiator antenna design, relying on the shape of the radiator itself and the radiation mechanism of the open space. The antenna performance is adjusted by controlling the antenna wiring in the non-metallic area and the layout of the metal part. The electronic device provided in this application embodiment is based on a rectangular resonant cavity structure. Utilizing the cavity resonance principle, the rectangular cavity can form a resonant cavity. By adjusting the size of the cavity (length L, width W, height H), parameters such as the resonant frequency can be controlled. At the same time, the metal enclosure structure of the cavity serves as a radiation-related part to achieve the regulation of antenna performance (such as resonance, radiation direction, etc.). The principle is more inclined towards cavity resonant antenna design. On the other hand, part of the radiator of the antenna module is designed on the upper surface and side of the antenna support. This part of the radiator can also generate coupling synchronously according to the gap with the first shell being less than or equal to 1mm, thereby enhancing radiation efficiency and expanding the antenna bandwidth.

[0156] This time, Figure 13 The pattern of the antenna radiator in the structure shown is different from the pattern of the antenna radiator in the electronic device provided in the embodiments of this application.

[0157] In summary, in the electronic device provided by the embodiments of this application, a portion of the signal generated by the antenna radiator is directly radiated to the outside of the accommodating space through the gap, and another portion is radiated to the outside of the accommodating space through the gap after electromagnetic resonance is excited in the resonant cavity. The portion of the signal generated by the antenna radiator that is radiated to the outside of the accommodating space through the gap after electromagnetic resonance is excited in the resonant cavity has strong directionality, thereby reducing the probability of generating signal "dead zone" or "side lobe abnormality" phenomena and improving the antenna performance of the electronic device.

[0158] Furthermore, in the electronic device provided in this application embodiment, only one slit is opened on the metal shell forming the resonant cavity. Whether the signal generated by the antenna radiator is radiated directly to the outside of the receiving space through the slit, or radiated to the outside of the receiving space through the slit after electromagnetic resonance is excited in the resonant cavity, it is radiated to the outside of the receiving space through the same slit. This reduces the number of slits opened on the metal shell of the electronic device, does not damage the integrated metal appearance of the product, is beneficial to the ID design of the electronic device, and can also reduce the mold complexity, assembly difficulty and material cost in the shell manufacturing process of the electronic device, thereby improving the market competitiveness of the product.

[0159] Furthermore, in the electronic device provided in this application embodiment, the antenna module can also use the same gap as the speaker module, so that the acoustic and electromagnetic functions share the same physical channel, and the antenna module design is more miniaturized, thereby providing more space for system stacking in the electronic device, which is beneficial to improving the flexibility of system design in the electronic device.
