Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to an electronic device. Background Technology

[0002] As people's living standards continue to improve and their lives become increasingly richer, their demands for communication quality in various scenarios are also rising. For example, the quality of phone calls and internet access under weak signal conditions (elevators, underground parking garages, outdoors, high-speed rail, subways, bedroom / bathroom corners, etc.). Therefore, the performance requirements for various communication functions of mobile terminals are becoming increasingly stringent, as are the requirements for the adaptability of antenna functions to different scenarios.

[0003] In related technologies, antenna scenario adaptation design requires the addition of new components or electronic devices, as well as the development of additional software algorithms, which increases the production cost of electronic devices. Summary of the Invention

[0004] The purpose of this application is to provide an electronic device that uses a battery metal compartment and connectors to form an antenna energy structure, thereby transferring the radiated energy on the antenna radiator and adapting to more communication scenarios.

[0005] In a first aspect, embodiments of this application provide an electronic device, including: a first radiator, a battery metal compartment, and a connector;

[0006] The first radiator includes a first end and a second end, and the feed point of the first radiator is located between the first end and the second end;

[0007] The battery metal compartment includes a first sidewall and a back plate, the first sidewall being disposed around the periphery of the back plate, and the back plate being grounded;

[0008] The first radiator is located outside the battery metal compartment, and there is a first gap between the first radiator and the first sidewall;

[0009] The connector is located within the first gap and connects a first portion of the first sidewall to a second portion of the first radiator; the second portion is located between the first end of the first radiator and the feed point.

[0010] A first through hole is provided on the first sidewall, the first through hole extends along the length direction of the first radiator, and the first through hole is located between the first part and the back plate; or, a distributed inductance is formed between the connector and the first sidewall.

[0011] In this embodiment, the first sidewall of the battery metal compartment is connected to the first radiator via a connector, and the backplate of the battery metal compartment is grounded. A distributed inductance grounding structure can be formed by opening a first through hole extending along the length direction of the first radiator on the first sidewall, or by using a connector connecting the first sidewall and the first radiator to form a distributed inductance with the first sidewall. In this way, the excitation current on the first radiator is grounded through the distributed inductance grounding structure, thereby transferring energy from the first region on the first radiator to the second region. The first region is the region between the first end and the first part, and the second region is the region between the first end and the second part. This allows part of the energy of the antenna module to be transferred to the hand-held area in landscape gaming scenarios away from electronic devices, reducing the impact of hand-held operation and improving antenna performance in such scenarios.

[0027] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0028] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] In related technologies, the metal frame of an electronic device can be used to form an antenna radiator. In this application embodiment, the electronic device can be any electronic device with an antenna, such as a mobile phone, tablet computer, base station, watch, or laptop. For ease of explanation, this application embodiment uses a mobile phone as an example for illustration, which does not constitute a specific limitation.

[0030] Mobile phones and other electronic devices can be held in various ways, such as portrait mode and landscape mode. In different holding scenarios, the user's hand will block part of the antenna on the electronic device, thus affecting the antenna performance.

[0031] In related technologies, the following methods can be used to overcome the problem of reduced antenna performance of communication devices caused by human body obstruction when the user holds the communication device:

[0032] 1) Antennas operating under various standards need to adapt to various scenarios, such as Long Term Evolution (LTE), New Radio (NR), Wireless Fidelity (WIFI), and Global Positioning System (GPS). However, the scenario adaptation design proposed in this solution usually focuses on the high-frequency part.

[0033] 2) Due to the size limitations of mobile terminals, low-frequency bands often cannot be modified in many ways, making their adaptability to different scenarios more prominent. Currently, the common approach is to add switches combined with software algorithms to switch between different antennas, or to add additional components, which are also common methods for mid-to-high frequency bands.

[0034] However, the above methods have at least the following drawbacks: First, the antenna scene adaptation design in related technologies is more focused on high frequencies; second, the antenna scene adaptation design in related technologies requires the addition of new components or electronic devices (such as antenna switches), as well as the development of software algorithms, which often require a significant increase in costs.

[0035] In this embodiment, the first sidewall of the battery metal compartment is connected to the first radiator via a connector, and the back plate of the battery metal compartment is grounded. A distributed inductance grounding structure can be formed by opening a first through hole extending along the length direction of the first radiator on the first sidewall, or by using a connector connecting the first sidewall and the first radiator to form a distributed inductance with the first sidewall. In this way, the excitation current on the first radiator is grounded through the distributed inductance grounding structure, thereby transferring the energy in the first region of the first radiator to the second region. The first region is the region between the first end and the first part, and the second region is the region between the first end and the second part. This allows part of the energy of the antenna module to be transferred to the hand-held area in landscape gaming scenarios away from electronic devices, reducing the impact of hand-held operation and improving antenna performance in such scenarios.

[0036] Furthermore, compared to related technologies, the embodiments of this application do not require the addition of new electronic components or the matching of software algorithms, thereby improving the antenna's adaptability to different scenarios while reducing the structural complexity and production cost of the antenna module.

[0037] It is worth noting that the antenna module in the electronic device provided in this application embodiment can be a low-frequency working module or a mid-to-high frequency antenna module. For ease of explanation, this application embodiment usually uses the antenna module as a low-frequency working module as an example for illustration, which does not constitute a specific limitation.

[0038] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios. Example

[0039] Please see Figure 1 An electronic device provided in this application includes: a first radiator 10, a battery metal compartment 20, and a connector 30;

[0040] The first radiator 10 includes a first end and a second end, and the feed point A of the first radiator 10 is located between the first end and the second end;

[0041] The battery metal compartment 20 includes a first sidewall D1 and a back plate G1. The first sidewall D1 is disposed around the periphery of the back plate G1, and the back plate G1 is grounded.

[0042] The first radiator 10 is located outside the battery metal compartment 20, and there is a first gap 31 between the first radiator 10 and the first sidewall D1;

[0043] The connector 30 is located within the first gap 31 and connects the first part B1 of the first sidewall D1 and the second part B2 of the first radiator 10. The second part B2 is located between the first end of the first radiator 10 and the feed point A.

[0044] A first through hole S1 is provided on the first sidewall D1. The first through hole S1 extends along the length direction of the first radiator 10 and is located between the first part B1 and the back plate G1; or, a distributed inductance is formed between the connector 30 and the first sidewall D1.

[0045] During operation, the feed F1 provides an excitation current to the first radiator 10 through the feed point A, wherein at least a portion of the excitation current is distributed to ground through the connector 30 with a distributed inductance, so that the connector 30 is used to transfer at least a portion of the excitation current in the first region on the first radiator 10 to the second region on the first radiator 10. The first region is the region between the first end and the feed point A, and the second region is the region between the first end and the second part B2.

[0046] In some embodiments, the first end of the first radiator 10 may be as follows: Figure 1 The first radiator 10 shown in the diagram faces the end of the second fracture SL1, and the second end of the first radiator 10 can be as follows: Figure 1The first radiator 10 shown is oriented toward the end of the third fracture SL2.

[0047] Optionally, the first end is located on the first long side of the electronic device, and the second end is located on the first short side of the electronic device, with the first long side adjacent to the first short side.

[0048] Feed point A can be located in the corner area between the first long side and the first short side. This corner area is located within the horizontal hand-holding area of ​​the electronic device. That is, the radiated energy in the first area will be blocked by the user's hand. If the radiated energy passes through the first area, it will affect the antenna performance.

[0049] Optionally, the first radiator 10 is divided into a first sub-radiator and a second sub-radiator, with feed point A as the boundary. The first sub-radiator and the second sub-radiator are respectively located on adjacent sides of the metal frame. For example, the first sub-radiator is the radiator between feed point A and the second break SL1, and the second sub-radiator is the radiator between feed point A and the third break SL2. In this case, it is assumed that the first sub-radiator is located on the long side of the metal frame, and the second sub-radiator is located on the short side of the metal frame.

[0050] At this time, the area between the power supply point A and the second part B2 can be located within the horizontal grip area of ​​the electronic device. The horizontal grip area refers to the area that the user's fingers hold or cover when the electronic device is in a horizontal application scenario.

[0051] Optionally, the second part B2 is located in the target area on the first long side, and the target area is located outside the horizontal hand-holding area of ​​the electronic device.

[0052] In this embodiment, the second part B2 is located outside the horizontal grip area of ​​the electronic device. When the radiated energy in the first area is transferred to the second area, the second area is also located outside the horizontal grip area of ​​the electronic device.

[0053] In some implementations, in order to place the second part B2 within the target area, the distance between the second part B2 and the first short side can be greater than or equal to 1 / 6 or 1 / 5 of the length of the first long side.

[0054] Optionally, the length of the first sub-radiator can be greater than or equal to half the long side of the metal frame, and the length of the second sub-radiator can be greater than or equal to half the short side of the metal frame.

[0055] When the length of the first sub-radiator is greater than or equal to half the long side of the metal frame, the area on the first sub-radiator near the first end is obviously outside the horizontal hand-held area of ​​the electronic device.

[0056] Optionally, the end of the second sub-radiator near the third slit SL2 can be grounded via a tuning module SW0, which can tune the frequency of the antenna.

[0057] Of course, for antenna radiators of different types or structures, the ends do not necessarily have to be separated. For example, the ends of the antenna radiator may be connected to other metal structures and grounded through a feed structure. Furthermore, the radiator can be placed in other areas of the metal frame, or even in other locations besides the metal frame. For ease of explanation, this embodiment uses the example of a first radiator 10 being placed on a metal frame, with a second separation SL1 and a third separation SL2 respectively provided at both ends. The specific structure of the first radiator 10 is not limited here.

[0058] In this embodiment, the first region on the first radiator 10 can be the region between the second break SL1 and the feed point A, and the second region on the first radiator 10 can be the region between the second break SL1 and the second part B2. That is, the energy transfer path can be from the feed point A to the second part B2, and the distributed inductance is grounded through the connector 30.

[0059] In some implementations, the position of the second part B2 can be adjusted according to the user's handheld area in different application scenarios, that is, the distance between the power supply point A and the second part B2 is adjustable.

[0060] For example: Figure 1 As shown, in landscape mode, the user's hand typically obscures objects such as... Figure 1 The lower right corner of the metal frame shown is located in the area between the power supply point A and the second part B2, which is within the obscured area in this landscape scene. The position of the second part B2 is adjusted to move the energy between the power supply point A and the second part B2 to outside the obscured area.

[0061] In some embodiments, electronic devices such as mobile phones are provided with a battery metal compartment 20, which is used to house a battery. A first radiator 10 can be disposed outside the battery metal compartment 20 and spaced apart from a first sidewall D1 of the battery metal compartment 20. That is, the first sidewall D1 can be a sidewall on the battery metal compartment 20 that is parallel to the second region on the first radiator 10 (i.e., the region between the second fracture SL1 and the second portion B2) and is closest to the first radiator 10. Furthermore, as... Figure 2 As shown, the back plate of the battery metal compartment 20 can be grounded, so the back plate of the battery metal compartment 20 can be regarded as the main ground. That is, the bottom of the first side wall D1 is connected to the main ground. In this way, the second part B2 on the first radiator 10 can be connected to the main ground through the connector 30 and the first side wall D1.

[0062] For example: Figure 1 As shown, the first radiator 10 is disposed on a metal frame, which surrounds the battery metal compartment 20 and has a gap between it and the periphery of the battery metal compartment 20. At this time, a connector 30 can be disposed in the first gap 31 between the side wall of the battery metal compartment 20 near the first radiator 10 and the first radiator 10, so that the second part B2 of the first radiator 10 can be grounded through the connector 30 and the battery metal compartment, thereby realizing the transfer of energy from the second part B2 to the feed point A to the second part B2 to the second fracture SL1.

[0063] It should be noted that, in implementation, such as Figure 1 The antenna module in the electronic device shown has the following three operating modes in the operating frequency band:

[0064] Bottom monopole mode M11, which is the monopole mode excited on the second sub-radiator;

[0065] The inverted-F antenna (IFA) mode M12 on the side is the IFA mode excited on the first sub-radiator;

[0066] The half-wavelength mode M21 on the entire first radiator 10.

[0067] One of the modes for achieving energy transfer is the side-mounted IFA mode M12, which involves transferring energy from the first region to the second region under the M12 mode.

[0068] It is worth noting that in related technologies, if the connector 30 is not connected to the battery metal compartment 20, the energy distribution on the first radiator 10 in the side-mounted IFA mode is between the feed point A and the second gap SL1. However, in this embodiment, in the side-mounted IFA mode, the energy distribution on the first radiator 10 is between the second part B2 and the second gap SL1, thereby achieving partial energy transfer. This facilitates flexible adjustment of the distribution range of antenna radiated energy on the first radiator 10. Thus, when applied to specific scenarios, the radiated energy on the first radiator 10 can be transferred to the area not blocked by the user's hand, based on the user's hand-held area, thereby improving antenna performance in that scenario.

[0069] In some implementations, given that directly grounding the second portion B2 via connector 3 might make it difficult to excite the IFA mode M12, a distributed inductor grounding structure can be provided at the high current point of the IFA mode M12. In this case, the distributed inductor grounding also allows energy across a wide frequency band to pass through the grounding point and excite the IFA mode M12 in the second region between the second gap SL1 and the second portion B2. Simultaneously, due to the introduction of this distributed inductor, there is better impedance matching across a wide frequency band. Therefore, within the operating frequency band, a traveling wave transmission characteristic is formed between the feed point A and the second portion B2, thereby more effectively transferring the side-mounted IFA mode M12 from the first region to the second region.

[0070] In one alternative implementation, the length direction of the first through hole S1 is parallel to the first radiator 10, which can be understood as: the length direction of the first through hole S1 is parallel to the portion of the first radiator 10 located in the second region.

[0071] The first through hole S1 is located between the first part B1 and the back plate G1. This can be understood as the first part B1 and the back plate G1 being located on either side of the first through hole S1. For example: Figure 2 As shown, a first through hole S1 extending laterally is provided on the first side D1, wherein the first part B1 is located on the upper side of the first through hole S1, and the back plate G1 is located on the lower side of the first through hole S1.

[0072] In this embodiment, a distributed inductance structure can be formed using the first through-hole S1, for example: Figure 2 As shown, based on the first through hole S1, the current at the second part B2 on the first radiator 10 can be grounded through the distributed inductance path L1 and the distributed inductance path L2. That is, the antenna energy flows back to the backplane G1 (i.e., the main ground) through the connector 30 via the two paths L1 and L2.

[0073] Optionally, the length of the first through-hole S1 is less than or equal to half the wavelength of the first operating frequency band of the antenna module corresponding to the first radiator 10.

[0074] In the case where the antenna module is a low-frequency antenna, the first operating frequency band of the antenna module can be a low-frequency band. In this case, the length of the first through hole S1 can be between 30-60mm.

[0075] In this embodiment, by controlling the length of the first through hole S1 to be within 1 / 2 wavelength of the first operating frequency band of the antenna module, the resonant interference generated by the first through hole S1 can be reduced.

[0076] It is worth mentioning that, in some embodiments, the length of the first through hole S1 can be adjusted to excite a high-frequency slot mode (such as N41 / N78 / N79) in the slot structure of the first through hole S1, thereby increasing the operating frequency band of the antenna module.

[0077] Optionally, the length of the region in the first radiator located between the feed point A and the second part B2 is less than or equal to half the wavelength of the first operating frequency band, where the first operating frequency band is the operating frequency band of the antenna module corresponding to the first radiator 10.

[0078] In the case where the antenna module is a low-frequency antenna, the operating frequency band of the antenna module can be a low-frequency band. That is, the length from the feed point A to the second part B2 is less than or equal to 1 / 2 wavelength of the operating frequency band of the antenna module.

[0079] It is worth noting that if the length from the feed point A to the second part B2 exceeds half the wavelength of the first operating frequency band of the antenna module, additional influencing modes may be introduced. In this case, it will interfere with the existing modes of the antenna module, such as the bottom monopole mode M11, the side IFA mode M12, and the half-wavelength mode M21 on the entire first radiator 10.

[0080] The first operating frequency band can be the operating frequency band corresponding to the bottom monopole mode M11, the side IFA mode M12, or the half-wavelength mode M21 on the entire first radiator 10, such as the low-frequency operating frequency band.

[0081] In another alternative implementation, the connector 30 can also be used to form a distributed inductance structure or an inductor can be connected in series with the connector 30. For example: Figure 11 As shown, the connector 30 includes a third connecting portion PL1 that is parallel to and spaced apart from the first sidewall D1. Thus, PL1 and the first sidewall D1 can form a distributed inductance, or, as... Figure 14 As shown, a second switching module Q1 can be connected in series on the connector 30 to adjust at least one of the grounding capacitor, resistor and inductor of the second part B2.

[0082] It is worth noting that, compared with the above-mentioned method of using the connector 30 to form a distributed inductor structure or connecting an inductor in series on the connector 30, the method of using the first through hole S1 on the first side D1 to realize the grounding of the distributed inductor is not necessary to increase the gap between the battery metal compartment 20 and the metal frame to set up the more complex connector 30, thus not occupying the space of the battery metal compartment 20 and not reducing the battery capacity.

[0083] Of course, while utilizing the first through hole S1 on the first side D1 to achieve grounding of the distributed inductance, it is also possible to set up, for example, Figure 11 The structure of the connector 30 shown is not specifically limited here.

[0084] Corresponding to Figure 1 and Figure 2 The electronic device shown has a first radiator 10 of the antenna module disposed on the metal frame of the mobile phone. In this case, the antenna module of the electronic device in this application embodiment can transfer part of the energy on the antenna radiator to improve the antenna performance of the electronic device in various scenarios.

[0085] Specifically, assuming as Figure 1 and Figure 2 The antenna module in the illustrated electronic device and the antenna module in the related technology both operate in the N28 (approximately 0.705 GHz - 0.805 GHz) frequency band. Therefore, if... Figure 4 As shown, Figure 1 and Figure 2 Compared to antenna modules that do not perform energy transfer, the antenna module in the electronic device shown has a significantly improved radiation efficiency in various scenarios, such as when the phone is held in the left hand and the phone in the right hand.

[0086] In addition, such as Figure 5 As shown, by comparing the low-frequency total efficiency in free space and left / right hand mold states, it can be concluded that in terms of total efficiency, as... Figure 1 and Figure 2 The antenna module shown is also significantly superior to antenna modules in related technologies. Example

[0087] like Figure 6 As shown, in this embodiment of the application, based on the above embodiment one, a first break S2 is also provided on the first sidewall D1. The first break S2 is connected to the first gap 31 and the first through hole S1, and the first part B1 is located on one side of the first break S2.

[0088] like Figure 6 In the illustrated embodiment, the example given is that the first part B1 is located on the left side of the first fracture S2, that is, on the side wall of the first fracture S2 near the second fracture joint SL1. In another embodiment, the first part B1 may be located on the right side of the first fracture S2, which is not specifically limited here. For ease of explanation, this embodiment uses the example of the first part B1 being located on the left side of the first fracture S2, which does not constitute a specific limitation.

[0089] In this embodiment, the first gap 31 and the first through hole S1 are connected by the first break S2. At this time, the grounding path of the antenna energy at the second part B2 is: connector 30 --> first part B1 --> L1 --> G1. The area of ​​the first through hole S1 located between the side wall on the right side of the first break S2 and the back plate G1 can form the resonant path L2.

[0090] In other words, in this embodiment, the ground return path L1 and the connector 30 are used to form an energy transmission section, and the first through hole S1 can form a high-frequency working resonance (such as N41 / N78 / N79). At the same time, the area between the side wall of the first through hole S1 located on the right side of the first break S2 and the back plate G1 can also form a high-frequency working resonance (such as N41 / N78 / N79), thereby greatly widening the working frequency band of the antenna module.

[0091] Optionally, the distance between the first part B1 and the first short side SC1 of the first through hole S1 is less than or equal to 1 / 2 wavelength of the first operating frequency band, and the first part B1 and the first short side SC1 are located on the same side of the first break.

[0092] Optionally, in actual engineering, the distance between the first part B1 and the first short side SC1 of the first through hole S1 can be controlled to be between 30-60mm.

[0093] In this embodiment, by limiting the distance between the first part B1 and the first short side SC1 of the first through hole S1 to be less than or equal to 1 / 2 wavelength of the first operating frequency band, the resonant interference generated by the slot between the first part B1 and the short side SC1 of the first through hole S1 can be reduced.

[0094] like Figure 3 As shown, the operating frequency band of the antenna module in the electronic device provided in Embodiment 1 of this application may include three bands: AL01, AL02 and AL03. AL01 and AL02 are two low-frequency operating resonances (formed by the M11 mode, M12 mode and M21 mode on the entire first radiator 10 between the second slot SL1 and the third slot SL2). AL03 is a resonance operating in the mid-to-high frequency range (corresponding to the half-wavelength slot mode formed by the first through-hole S1, which can be N41 or other frequency bands).

[0095] like Figure 7As shown, the antenna module in the electronic device provided in Embodiment 2 of this application may include four operating frequency bands: AL1, AL2, AL3 and AL4. AL1 and AL2 are two low-frequency operating resonances (formed by the M11 mode, M12 mode and M21 mode on the entire first radiator 10 between the second gap SL1 and the third gap SL2). AL3 is a resonance operating in the mid-to-high frequency range (corresponding to the half-wavelength slot mode formed by the first through hole S1, which can be N41 or other frequency bands). AL4 is a resonance operating in the higher frequency range (corresponding to the IFA 1 / 4 wavelength mode formed in the area between the right sidewall of the first through hole S1 and the back plate G1, which can be N78 or N79 or other frequency bands).

[0096] have Figure 3 and Figure 7 It can be concluded that the above embodiment 2 can increase the operating frequency band of the antenna module in the mid-to-high frequency range by adding the first break S2. Example

[0097] Please see Figure 8 Compared to Embodiment 2 described above, this embodiment adds a first switching module 40 between the two ends of the first break S2. The first switching module 40 is connected between the two ends of the first break S2, and its first parameter is adjustable, including at least one of capacitance, resistance, and inductance values.

[0098] Optionally, in some embodiments, the first switching module 40 may include at least one of the following devices: a switching switch, a capacitor, a resistor, an inductor, etc. Based on the first switching module 40, at least one of the capacitance, resistance, and inductance values ​​between the opposite side walls of the first break S2 can be adjusted.

[0099] For example: Figure 9 As shown, the first switching module 40 may include a switching switch SW1. One end of the switching switch SW1 is connected to one side wall of the first break S2, and the other end of the switching switch SW1 is connected to the other side wall of the first break S2 through different resistive, capacitive and inductive devices such as the first inductor LG1, the second inductor LG2, and the first capacitor CG1. In this way, at least one of the capacitance, resistance and inductance values ​​between the two opposite side walls of the first break S2 can be switched by the switching switch SW1.

[0100] Optionally, the first switching module 40 can be spot-welded between the opposite side walls of the first break S2 on a flexible printed circuit (FPC), or it can be connected between the opposite side walls of the first break S2 on a rigid board such as a printed circuit board (PCB) via a spring clip.

[0101] In this embodiment, the first switching module 40 can be used to adjust at least one of the capacitance, resistance and inductance values ​​between the two opposite side walls of the first break S2, so as to achieve frequency tuning of the moved M12 mode, thereby enabling the antenna module to work in more frequency bands and improving antenna performance in hand-held scenarios in more low frequency bands.

[0102] For example: Figure 10 As shown, by adjusting at least one of the capacitance, resistance, and inductance values ​​between the opposite side walls of the first break S2 through the first switching module 40, it is possible to achieve the following: Figure 7 The AL1 and AL2 frequency bands shown are switched from the N28 frequency band to the N8 frequency band, and / or, will Figure 7 The AL3 band shown is switched from the N41 band to the N3 band, and / or, will Figure 7 The AL4 band can be switched from the N78 band to the N79 band or the WIFI 5G band. Example

[0103] Compared with Embodiment 1 above, the connector 30 is improved in this application embodiment.

[0104] like Figure 11 or Figure 12 As shown, the connector 30 includes: a first connecting part P2, a second connecting part P1 and a third connecting part PL1;

[0105] The first connecting part P2 is connected to the first part B1, the second connecting part P1 is connected to the second part B2, and the third connecting part PL1 is connected between the first connecting part P2 and the second connecting part P1.

[0106] In this embodiment, the first connecting part P2, the second connecting part P1 and the third connecting part PL1 can be located on the same straight line or on different straight lines.

[0107] For example: Figure 11As shown, the third connecting portion PL1 is parallel to and spaced apart from the first sidewall D1, and the first connecting portion P2 and the second connecting portion P1 are located at opposite ends of the third connecting portion PL1. In this case, a distributed inductance grounding structure can be formed through the gap between the third connecting portion PL1 and the first sidewall D1, thus eliminating the need to open a first through hole S1 on the first sidewall D1. Compared to the embodiment where a first through hole S1 is opened on the first sidewall D1, this improves the structural strength of the battery metal compartment 20.

[0108] For example: Figure 12 As shown, the first connecting part P2, the second connecting part P1 and the third connecting part PL1 can be located on the same straight line. In this case, a first through hole S1 can be opened on the first side wall D1 to form a distributed inductance grounding structure.

[0109] In one implementation, such as Figure 11 or Figure 12 As shown, the first connecting part P2, the second connecting part P1 and the third connecting part PL1 can together form a metal ultrasonic FPC. In this case, ultrasonic welding of the FPC can be used to achieve the connection between the first connecting part P2 and the first part B1, and the connection between the second connecting part P1 and the second part B2.

[0110] In another implementation, such as Figure 13 As shown, a small board 32, such as a PCB, FPC, liquid crystal polymer (LCP), or modified polyimide (MPI) circuit board, can be set in the first gap 31. A first spring TP1 and a second spring TP2 can be set at both ends of the small board 32, respectively. The small board 32 can be horizontally or vertically embedded in the plastic in the first gap 31. In this way, one end of the first spring TP1 is fixedly connected to the small board 32, and the other end is used to press it onto the first part B1; one end of the second spring TP2 is fixedly connected to the small board 32, and the other end is used to press it onto the second part B2. The first spring TP1 and the second spring TP2 can be connected on the small board 32 by a metal wire.

[0111] In other words, the first spring TP1 serves as the first connecting part, the second spring TP2 serves as the second connecting part, and the metal wire connecting the first spring TP1 and the second spring TP2 serves as the third connecting part.

[0112] This embodiment utilizes a connection method where a spring is pressed onto the corresponding part, compared to... Figure 11 or Figure 12As shown in the ultrasonic welding FPC connection method, ultrasonic welding is not required, which reduces the complexity and cost of antenna module assembly. At the same time, compared with the above welding structure, it can also improve connection reliability, for example, the weld may crack under impact. Example

[0113] like Figure 14 As shown, in this embodiment, as Figure 13 Based on the embodiment shown, a second switching module Q1 is connected in series on the metal line on the small board 32 used to connect the first spring TP1 and the second spring TP2.

[0114] Optionally, the third connecting portion includes:

[0115] The second switching module Q1 is connected in series between the first connection part and the second connection part. The second parameter of the second switching module Q1 is adjustable, and the second parameter includes at least one of capacitance value, resistance value and inductance value.

[0116] Optionally, the structure of the second switching module Q1 is similar to that of the first switching module 40. For example, the second switching module Q1 may include at least one of the following devices: a switching switch, a capacitor, a resistor, an inductor, etc. Based on the second switching module Q1, at least one of the capacitance, resistance, and inductance values ​​between the first spring TP1 and the second spring TP2 can be adjusted.

[0117] The second switching module Q1 can be connected in series between the first spring TP1 and the second spring TP2 via a metal wire on the small board 32.

[0118] For example: Figure 15 As shown, the second switching module Q1 may include a switching switch SW2. One end of the switching switch SW2 is connected to the first spring TP1, and the other ends of the switching switch SW2 are connected to the second spring TP2 through different resistive, capacitive and inductive devices such as the third inductor L01, the fourth inductor L02, and the second capacitor C01. In this way, at least one of the capacitance, resistance and inductance values ​​between the first spring TP1 and the second spring TP2 can be switched by the switching switch SW2.

[0119] This fifth embodiment has the same characteristics as... Figure 13 The spring-loaded connection structure shown in the diagram has the same beneficial effects. Furthermore, the second switching module Q1 can adjust at least one of the capacitance, resistance, and inductance values ​​between the first spring-loaded TP1 and the second spring-loaded TP2 to achieve tuning functions for more operating frequency bands, such as: obtaining the same values ​​as shown in the diagram. Figure 10 The effect shown is to increase the operating frequency band of the antenna module.

[0120] Optionally, the electronic device provided in this application embodiment can be a terminal, or it can be a device other than a terminal. The terminal can be a mobile electronic device or a non-mobile electronic device. For example, mobile electronic devices can be mobile phones, tablets, laptops, handheld computers, in-vehicle electronic devices, mobile internet devices (MID), augmented reality (AR) / virtual reality (VR) devices, robots, wearable devices, ultra-mobile personal computers (UMPCs), netbooks, or personal digital assistants (PDAs), etc. Non-mobile electronic devices can also be servers, network attached storage (NAS), personal computers (PCs), televisions (TVs), ATMs, or self-service machines, etc. This application embodiment does not specifically limit the scope.
