Description

Technical Field

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

[0002] With the development of communication technology, electronic devices such as smartphones are able to perform more and more functions, and their communication modes are becoming more diversified. Each communication mode requires a corresponding antenna to support it, and the performance of the antenna directly determines the communication quality and the user experience.

[0003] However, factors such as user hand posture and the folding shape of electronic devices can easily affect the antenna performance of electronic devices. Therefore, there is an urgent need to provide an antenna solution that is less affected by factors such as user hand posture and the folding shape of electronic devices. Summary of the Invention

[0004] This application provides an electronic device that, even when held by a user in a folded state, still possesses superior positioning signal antenna performance.

[0005] This application provides an electronic device, including:

[0006] The first body includes a first short border, a portion of a first long border, and a portion of a second long border;

[0007] The second body includes a second short frame, another part of a first long frame, and another part of a second long frame. The second body can be folded or unfolded relative to the first body, so that the first short frame overlaps with the second short frame in the folded state, and the length of the first short frame or the second short frame is less than the length of the first long frame or the second long frame in the unfolded state.

[0008] A first radiator is disposed on the first short frame. The first radiator includes a first end, a first feed point, a first ground point, a second ground point, a second feed point, and a second end arranged in sequence.

[0009] A first feed source is electrically connected to the first feed point. The first feed source is used to excite the radiation segment between the first end and the first ground point to support the first positioning signal, or to support the first positioning signal and the first Wi-Fi signal simultaneously.

[0010] The second feed source is electrically connected to the second feed point. The second feed source is used to excite the radiation segment between the second end and the second ground point to support the second positioning signal in the same frequency band as the first positioning signal.

[0011] A metal decorative element is disposed on the first body or the second body, and the metal decorative element is grounded; and

[0012] A third feed source is electrically connected to the metal decorative component, and the third feed source is used to excite the metal decorative component to support a third positioning signal with a different frequency band than the first positioning signal.

[0013] In the electronic device of this application, a first radiating segment between the first end of the first radiator and the first grounding point, together with the first feed source, can form a first positioning antenna and support a first positioning signal. A second radiating segment between the second end and the second grounding point, together with the second feed source, can form a second positioning antenna and support a second positioning signal in the same frequency band as the first positioning signal. A metal decorative piece and a third feed source can form a third positioning antenna and support a third positioning signal in a different frequency band than the first positioning signal. When the electronic device is in a folded state where the first short frame of the first body and the second short frame of the second body overlap, it is not easy for the user to hold the first positioning antenna and the second positioning antenna at the same time, nor is it easy for the user to hold the metal decorative piece. This allows the electronic device of this application to still support two positioning signals in different frequency bands when folded and held in hand. The electronic device has good anti-grip performance when folded and held in hand, and the positioning performance of the electronic device is superior. Attached Figure Description

[0029] The following will refer to the appendices in the embodiments of this application. Figure 1 To be continued Figure 14 The technical solutions in the embodiments of this application are clearly and completely described. 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.

[0030] This application provides an electronic device 10, which can be a smartphone, tablet computer, or other device, as well as a gaming device, augmented reality (AR) device, automotive device, data storage device, audio playback device, video playback device, laptop computer, desktop computing device, etc. The electronic device 10 has wireless communication capabilities. For example, the electronic device 10 can transmit Wireless Fidelity (Wi-Fi) signals, Global Positioning System (GPS) signals, 3rd Generation (3G), 4th Generation (4G), 5th Generation (5G), Near Field Communication (NFC) signals, Bluetooth (BT) signals, Ultra Wide Band (UWB) signals, etc.

[0031] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a first structure of the electronic device 10 provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows a partial structural schematic of the electronic device 10. The electronic device 10 includes a mid-frame 400, a first radiator 110, a first feed source 121, and a second feed source 122.

[0032] The middle frame 400 includes a first long frame 410 and a second long frame 420 disposed opposite to each other, and a first short frame 430 and a second short frame 440 disposed opposite to each other. A first radiator 110 is disposed on the first short frame 430. The first radiator 110 includes a first end 111, a first feed point 112, a first ground point 113, a second ground point 114, a second feed point 115, and a second end 116 arranged in sequence, such that a first radiating segment 117 can be formed between the first end 111 and the first ground point 113, and a second radiating segment 118 can be formed between the second end 116 and the second ground point 114. The first radiator 110 may include the first radiating segment 117, the second radiating segment 118, and the radiating segment between the two ground points. The first feed source 121 is directly or indirectly electrically connected to the first feed point 112. The first feed source 121 is used to excite the first radiating segment 117 between the first end 111 and the first ground point 113 to support the first positioning signal, or the first feed source 121 is used to excite the first radiating segment 117 to simultaneously support the first positioning signal and the first Wi-Fi signal. The second feed source 122 is directly or indirectly electrically connected to the second feed point 115. The second feed source 122 is used to excite the second radiating segment 118 between the second end 116 and the second ground point 114 to support the second positioning signal.

[0033] It is understood that the middle frame 400 can be a hollow frame structure or a thin plate structure. The middle frame 400 is used to provide support for the electronic devices or functional components in the electronic device 10, so as to install the electronic devices or functional components of the electronic device 10 together. For example, the middle frame 400 can be provided with structures such as grooves, protrusions, and through holes to facilitate the installation of electronic devices or functional components of the electronic device 10. The first long side 410, the first short side 430, the second long side 420, and the second short side 440 of the middle frame 400 can be connected sequentially to form a rectangular structure and form the outer frame of the electronic device 10. The first long side 410 and the second long side 420 can extend along the first direction H1, and the first short side 430 and the second short side 440 can be set along the second direction H2. The length of the first long side 410 and the second long side 420 along the first direction H1 can be greater than the length of the first short side 430 and the second short side 440 along the second direction H2. Wherein, the second direction H2 can be perpendicular to the first direction H1. When the first direction H1 is the length direction of the electronic device 10, the second direction H2 can be the width direction of the electronic device 10. Furthermore, as... Figure 1 As shown, the first short border 430 can be the top border of the electronic device 10 in a vertical orientation, and the second short border 440 can be the bottom border of the electronic device 10 in a vertical orientation. The first short border 430 is positioned towards the sky in the vertical orientation of the electronic device 10, and the second short border 440 is positioned towards the ground in the vertical orientation of the electronic device 10. When the electronic device 10 is in a vertical orientation... Figure 1When the user holds the device vertically, the user's hand is more likely to hold the first long frame 410 and the second long frame 420 of the electronic device 10, but less likely to hold the first short frame 430.

[0034] It is understood that when the first short frame 430 of the middle frame 400 includes a metal structure, the first short frame 430 may, but is not limited to, form metal branches through slots, and the first radiator 110 may include these metal branches, thereby the first radiator 110 can be formed on the first short frame 430. Of course, when the first short frame 430 of the middle frame 400 does not include a metal structure, the first radiator 110 may also be disposed on the first short frame 430 in the form of a mode-deformed antenna (MDA). It should be noted that the first radiator 110 may also be disposed on the first short frame 430 in other forms, and this application embodiment does not limit the specific manner in which the first radiator 110 is disposed on the first short frame 430.

[0035] It is understood that the first end 111 and the second end 116 of the first radiator 110 can be two free ends, open sections, or ends of the first radiator 110. The electronic device 10 may also include a ground plane 130. The first ground point 113 and the second ground point 114 can be directly or indirectly electrically connected to the ground plane 130 to achieve grounding. Thus, the first radiating section 117 between the first end 111 and the first ground point 113 can form a radiating structure, and the second radiating section 118 between the second end 116 and the second ground point 114 can form another radiating structure. When the first feed 121 is electrically connected to the first feed point 112 between the first end 111 and the first ground point 113, the first feed 121 and the first radiating section 117 can form a first positioning antenna. Under the action of the first feed 121, the first positioning antenna can at least support a first positioning signal. When the second feed source 122 is electrically connected to the second feed point 115 between the second terminal 116 and the second ground point 114, the second feed source 122 and the second radiating segment 118 can form a second positioning antenna. Under the action of the second feed source 122, the second positioning antenna can at least support the second positioning signal. Thus, the electronic device 10 of this application embodiment can be provided with two positioning antennas on the first short frame 430.

[0036] It is understood that the first positioning signal supported by the first positioning antenna and the second positioning signal supported by the second positioning antenna can be, but are not limited to, GPS signals, BeiDou Navigation Satellite System (BDS) signals, Galileo signals, and GLONASS signals. The first positioning signal supported by the first positioning antenna and the second positioning signal supported by the second positioning antenna can share the same frequency band. For example, both the first and second positioning signals can be GPS-L1 band signals (1575.42MHz±1.023MHz), or both can be GPS-L5 band signals (1166.45MHz±1.023MHz). Of course, the first and second positioning signals can be signals from different frequency bands; for example, one positioning signal can be a GPS-L1 band signal, and the other can be a GPS-L5 band signal. This application does not limit this aspect.

[0037] It is understood that the ground plane 130 can form the common ground of the electronic device 10. The ground plane 130 can be a plane or structure with zero potential. The ground plane 130 can be formed through conductors, printed circuits, or metal printed layers in the electronic device 10; or, the ground plane 130 can be formed on the motherboard, small board, or other carrier board of the electronic device 10; or, the ground plane 130 can also be formed on the frame of the electronic device 10 (e.g., the first middle board 450 and the second middle board 460 mentioned later). This application embodiment does not limit the specific location of the ground plane 130. The first grounding point 113 and the second grounding point 114 can be grounded to the ground plane 130 through grounding pads, grounding springs, etc., but are not limited to these methods.

[0038] It is understood that the area between the first grounding point 113 and the second grounding point 114 of the first radiator 110 can be grounded to reduce interference between the first positioning antenna and the second positioning antenna. Of course, the area between the first grounding point 113 and the second grounding point 114 may not require additional grounding points, or the first grounding point 113 and the second grounding point 114 may coincide so that the first radiating segment 117 and the second radiating segment 118 share the same grounding point. This application does not limit this aspect.

[0039] In the electronic device 10 of this application embodiment, the first radiator 110 is disposed on the first short frame 430 of the middle frame 400. The first radiating segment 117 between the first end 111 and the first grounding point 113 and the second radiating segment 118 between the second end 116 and the second grounding point 114 of the first radiator 110 can both be disposed on the first short frame 430. When both the first radiating segment 117 and the second radiating segment 118 support positioning signals, the electronic device 10 of this application can include two positioning antennas. The first short frame 430 can be provided with the radiating structure of two positioning antennas. When the user holds the electronic device 10 vertically, it is not easy to hold two positioning antennas at the same time, which can ensure the positioning antenna performance of the electronic device 10 in the hand-held state. The anti-hand-holding performance of the electronic device 10 when supporting positioning signals is better.

[0040] In this regard, please combine Figure 1 and Figure 2 Please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of a second structure of the electronic device 10 provided in the embodiments of this application. Figure 4 for Figure 3 A schematic diagram of the electronic device 10 in another state. (See diagram below.) Figure 3 and Figure 4 As shown, the electronic device 10 may also include a first body 200 and a second body 300, which can move toward each other so that the electronic device 10 has a foldable structure.

[0041] It is understood that the first long frame 410 includes a first part 411 and a second part 412 connected to each other, and the second long frame 420 includes a third part 421 and a fourth part 422 connected to each other. The electronic device 10 may also include a hinge structure 500, which allows the electronic device 10 to be folded along an axis extending in the second direction H2. This axis can serve as the dividing line between the first part 411 and the second part 412, as well as the dividing line between the third part 421 and the fourth part 422, so that the first body 200 includes a first short frame 430, a portion of the first long frame 410 (e.g., the first part 411), and a portion of the second long frame 420 (e.g., the third part 421); the second body 300 may include a second short frame 440, another portion of the first long frame 410 (e.g., the second part 412), and another portion of the second long frame 420 (e.g., the fourth part 422). The second body 300 can be folded or unfolded relative to the first body 200 along the axis of the electronic device 10. In the unfolded state, the first portion 411 and the second portion 412 of the first long frame 410 can form a first long frame 410 extending along the first direction H1, and the third portion 421 and the fourth portion 422 of the second long frame 420 can form a second long frame 420 extending along the first direction H1. The first short frame 430 and the second short frame 440 can be arranged opposite each other and form the top frame and bottom frame of the electronic device 10, respectively. The first short frame 430 can be set towards the sky, and the second short frame 440 can be set towards the ground. In the unfolded state, the lengths (e.g., the dimensions along the second direction H2) of the first short frame 430 and the second short frame 440 are smaller than the lengths (e.g., the dimensions along the first direction H1) of the first long frame 410 and the second long frame 420. In the folded state, the first portion 411 and the second portion 412 of the first long frame 410 can overlap each other, the third portion 421 and the fourth portion 422 of the second long frame 420 can overlap each other, and the first short frame 430 and the second short frame 440 can also overlap each other.

[0042] It is understood that the mid-frame 400 of the electronic device 10 may also include a mid-plate, such as a first mid-plate 450 and a second mid-plate 460, which can provide support for the electronic devices or functional components of the electronic device 10. The first body 200 may include the first mid-plate 450, and the second body 300 may include the second mid-plate 460. The first short frame 430, the first portion 411 of the first long frame 410, and the third portion 421 of the second long frame 420 may be connected to the first mid-plate 450. The second short frame 440, the second portion 412 of the first long frame 410, and the fourth portion 422 of the second long frame 420 may be connected to the second mid-plate 460. When the first mid-plate 450 and the second mid-plate 460 include conductive structures, the ground plane 130 of the electronic device 10 may be formed on at least one structure of the first mid-plate 450 and the second mid-plate 460. For example, the ground plane 130 may include a first grounding region and a second grounding region. The first grounding region may be formed on the first intermediate plate 450, and the second grounding region may be formed on the second intermediate plate 460. Of course, it should be noted that the ground plane 130 of the electronic device 10 may also be formed on other structures of the electronic device 10, and this application embodiment does not limit this.

[0043] It is understandable that when the electronic device 10 is folded along its axis (also known as vertical folding or small folding), the size of the electronic device 10 along the first direction H1 becomes smaller, and the compact electronic device 10 is more popular with female users. However, with this small folding electronic device 10, on the one hand, the antennas on the overlapping first body 200 and second body 300 will also overlap, causing mutual interference; on the other hand, the smaller size of the folded electronic device 10 along the first direction H1 makes it easier for the user to hold the electronic device 10, which makes the antenna of the folded electronic device 10 more susceptible to the influence of the user's grip, resulting in poorer anti-grip performance of the folded electronic device 10.

[0044] For example, please refer to Figure 5 and Figure 6 , Figure 5 for Figure 4 The diagram shown illustrates the structure of the electronic device 10 in a hand-held state. Figure 6 for Figure 4 The diagram shows the electronic device 10 in another hand-held position. Figure 5 As shown, when the electronic device 10 is folded up and down along the axis, and when the user holds the folded electronic device 10 in a posture such as with their left hand, the first long frame 410 and the second long frame 420 of the electronic device 10 along the first direction H1 are relatively easy for the user to hold. Parts of the first short frame 430 and the second short frame 440 of the electronic device 10 along the second direction H2 are held by the user, while other parts are not. Figure 6As shown, when the user holds the folded electronic device 10 in another posture, such as with their right hand, the first long frame 410 and the second long frame 420 of the electronic device 10 along the first direction H1 are also easier for the user to hold, and a portion of the first short frame 430 and the second short frame 440 of the electronic device 10 along the second direction H2 is held by the user (this area is different from...). Figure 5 The area shown is where the first short frame 430 and the second short frame 440 are held when the left hand is gripping the device; the other part is not held by the user. In other words, in the folded state, the first long frame 410 and the second long frame 420 of the electronic device 10 along the first direction H1 are essentially completely held by the user's hand. In related technologies, electronic devices 10 often place the positioning antenna on the long frame. When this positioning antenna is applied to a new form of vertically folding electronic device 10, its performance is significantly reduced, resulting in lower anti-grip performance.

[0045] In the electronic device 10 of this application embodiment, the first radiator 110 is disposed on the first short frame 430, and the first radiating segment 117 and the second radiating segment 118 of the first radiator 110 are also disposed on the first short frame 430. Two positioning radiating structures can be disposed on the first short frame 430. When the electronic device 10 is in an unfolded or folded state, it is not easy for the user to simultaneously hold the first radiating segment 117 and the second radiating segment 118 when holding the electronic device 10 with either their left or right hand. It is also not easy for the user to completely hold both positioning antennas. This ensures that at least one of the two positioning antennas in this application is not held by the user, which can guarantee the positioning performance of the electronic device 10 and improve the anti-grip performance of the electronic device 10 in the folded state.

[0046] It should be noted that when the electronic device 10 is folded along its axis, the first body 200 can be folded towards the direction of the second body 300. In this case, the first short frame 430 and the second short frame 440 overlap and are both located at the bottom of the folded electronic device 10. Alternatively, the second body 300 can be folded towards the direction of the first body 200. In this case, the first short frame 430 and the second short frame 440 overlap and are both located at the top of the folded electronic device 10. Since the positioning satellite is located at the top of the sky, to improve the positioning performance of the electronic device 10, this application allows the second body 300 to fold towards the first body 200, with the first short frame 430 facing the sky. In practical use, a secondary display screen (e.g., ...) can be installed on the back of the second body 300. Figure 5 and Figure 6(Shadowed area of ​​the quadrilateral in the middle) When the electronic device 10 is in a folded state, the user can perform display operations through the secondary display screen on the back of the second body 300. At this time, due to the limited setting position of the secondary display screen, the user will often fold the second body 300 towards the first body 200 along the axis, so that the first short frame 430 after folding can still face the sky.

[0047] To improve the positioning performance of the electronic device 10, it can control the first feed 121 and the second feed 122 to operate simultaneously. In this case, the first radiating segment 117 and the second radiating segment 118 can simultaneously support positioning signals in the same frequency band. The electronic device 10 can achieve positioning through two positioning antennas, resulting in more accurate positioning. Furthermore, the electronic device 10 also controls the feed corresponding to the stronger positioning signal among the first and second positioning signals to operate, allowing it to select the more powerful positioning antenna to operate, thus ensuring the positioning performance of the electronic device 10.

[0048] For example, please refer to Figure 7 , Figure 7 This is a schematic diagram of a circuit structure of an electronic device 10 according to an embodiment of this application. When the first positioning signal and the second positioning signal are positioning signals of the same type and frequency band, taking the first positioning signal and the second positioning signal as GPS-L1 frequency band signals as an example, the electronic device 10 may include a GPS-L1 frequency band signal radio frequency path. The electronic device 10 may include a positioning signal radio frequency module 21 (e.g., a GPS-L1 frequency band radio frequency module) and a switching switch 22. The output terminal of the positioning signal radio frequency module 21 can be electrically connected to the input terminal a1 of the switching switch 22. One output terminal of the switching switch 22, such as the first output terminal b1, can be electrically connected to the first feed point 112 to achieve an electrical connection with the first radiation segment 117. The other output terminal of the switching switch 22, such as the second output terminal b2, can be electrically connected to the second feed point 115 to achieve an electrical connection with the second radiation segment 118. When the input terminal a1 of the switch 22 is connected to the first output terminal b1, the first radiating segment 117 between the first end 111 of the first radiator 110 and the first ground point 113 can form a first radio frequency link with the positioning signal radio frequency module 21. The first radiating segment 117 can support the first positioning signal in the GPS-L1 frequency band. When the input terminal a1 of the switch 22 is connected to the second output terminal b2, the second radiating segment 118 between the second end 116 of the first radiator 110 and the second ground point 114 can form a second radio frequency link with the positioning signal radio frequency module 21. The second radiating segment 118 can support the second positioning signal in the GPS-L1 frequency band. Thus, under the switching of the switch 22, the electronic device 10 can select either the first radiating segment 117 or the second radiating segment 118 to support the positioning signal.

[0049] It is understandable that the output terminal of the positioning signal radio frequency module 21 and the input terminal a1 and the first output terminal b1 of the switching switch 22 can form the first feed 121 of the electronic device 10, and the output terminal of the positioning signal radio frequency module 21 and the input terminal a1 and the second output terminal b2 of the switching switch 22 can form the second feed 122 of the electronic device 10. Thus, the electronic device 10 can control the operation of the first feed 121 or the second feed 122 through the switching switch 22.

[0050] It is understandable that when the electronic device 10 is in a folded or unfolded state, the first positioning signal supported by the first radiating segment 117 and the second positioning signal supported by the second radiating segment 118 may be interfered with by the user's grip or other interference factors. At this time, the electronic device 10 can obtain the signal strength of the first positioning signal and the signal strength of the second positioning signal (for example, the electronic device 10 can control the input terminal a1 of the switching switch 22 to be connected to the first output terminal b1 and the second output terminal b2 respectively to obtain the signal strength of the first positioning signal and the second positioning signal respectively). Then, the electronic device 10 can select the positioning signal with the greater signal strength and control the switching switch 22 to connect the corresponding link so that the feed source corresponding to the positioning signal works. The electronic device 10 can perform the positioning function with the positioning signal with better performance, and the positioning performance of the electronic device 10 is better.

[0051] It is understandable that, such as Figure 7 As shown, the electronic device 10 may also include other radio frequency devices, such as filters 23 and power amplifiers 24. Filter 23 refers to a device that can effectively filter out a specific frequency or frequencies other than a specific frequency to obtain a signal of that specific frequency or eliminate a signal of that specific frequency. Power amplifier 24 refers to a device that amplifies weak signals. The first radio frequency link formed by the first radiating segment 117 and the positioning signal radio frequency module 21 may include one or more filters 23 and power amplifiers 24; the second radio frequency link formed by the second radiating segment 118 and the positioning signal radio frequency module 21 may also include one or more filters 23 and power amplifiers 24. This application embodiment does not limit this aspect.

[0052] It is understandable that, considering that the area of ​​the first short frame 430 held by the user is different when the user holds the electronic device 10 with their left hand and when the user holds the electronic device 10 with their right hand, the electronic device 10 can also control the operation of the first feed source 121 and the second feed source 122 according to the user's holding posture. For example, when the electronic device 10 is in a folded state with its display facing the user, if the user holds the electronic device 10 vertically with their left hand, it is easy to block the second radiating segment 118; if the user holds the electronic device 10 vertically with their right hand, it is easy to block the first radiating segment 117. Therefore, if the left-hand grip posture is detected when the electronic device 10 is folded, the electronic device 10 can directly control the first feed source 121 to operate (e.g., control the switch 22 to turn on input terminal a1 and first output terminal b1), so that the first feed source 121 excites the first radiating segment 117 to support the first positioning signal. If the right-hand grip posture is detected when the electronic device 10 is folded, the electronic device 10 can directly control the second feed source 122 to operate (e.g., control the switch 22 to turn on input terminal a1 and second output terminal b2), so that the second feed source 122 excites the second radiating segment 118 to support the second positioning signal. Thus, the electronic device 10 can use a stronger positioning signal for positioning, resulting in higher positioning accuracy.

[0053] It is understood that the electronic device 10 can determine the user's grip posture using, but is not limited to, a posture sensor or a proximity sensor. For example, the electronic device 10 may include a proximity sensor that can detect the proximity state between the electronic device 10 and an object (e.g., the user's hand), so that the electronic device 10 can control the operation of the first feed source 121 or the second feed source 122 based on the proximity state. For example, the electronic device 10 may set multiple proximity detection areas in the first long frame 410, the second long frame 420, the first short frame 430, the second short frame 440, or other areas, and then determine the proximity state between the electronic device 10 and the object (e.g., the user's hand) based on the detection results of the multiple proximity detection areas to obtain the user's grip posture; subsequently, the electronic device 10 can control the operation of the first feed source 121 or the second feed source 122 based on the proximity state or grip posture.

[0054] It should be noted that the electronic device 10 can also control the operation of the first feed source 121 or the second feed source 122 in other ways, and this application embodiment does not limit this.

[0055] Please refer to the following: Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of an S11 curve and an efficiency curve of an electronic device 10 provided in an embodiment of this application. Figure 9 This is a schematic diagram of the radiation direction of an electronic device 10 according to an embodiment of this application. Figure 8 Curves S1 and S2 are the S11 curve and antenna efficiency curve, respectively, when the second feed 122 excites the second radiating segment 118 to support the second positioning signal, such as the GPS-L1 band signal. As can be seen from curves S1 and S2, the second radiating segment 118 has superior antenna performance when supporting the GPS-L1 band signal. Furthermore, Figure 9 The radiation pattern for the second radiation band 118 supporting GPS-L1 band signals is provided by Figure 9 It can be seen that the second radiation band 118 supports GPS-L1 band signals with a higher proportion in the upper hemisphere, allowing the electronic device 10 to communicate better with GPS satellites, thus resulting in better GPS performance of the electronic device 10.

[0056] It is understood that when the first positioning signal and the second positioning signal are positioning signals of different types or different frequency bands, the electronic device 10 can also use the above-mentioned radio frequency architecture (if the first positioning signal and the second positioning signal are positioning signals of different types, the electronic device 10 may include a positioning signal radio frequency module corresponding to the two positioning signals, and the switching switch 22 can select a suitable positioning signal radio frequency module to be turned on with the corresponding radiation band) to select the positioning signal with stronger signal strength for positioning. This application embodiment does not limit this.

[0057] It is understandable that when the first positioning signal and the second positioning signal are positioning signals of different types or different frequency bands, the electronic device 10 can also control the first feed source 121 and the second feed source 122 to work simultaneously. For example, if the first positioning signal and the second positioning signal share the same positioning signal RF module 21, then the switch 22 can control the input terminal a1 to be simultaneously connected to the first output terminal b1 and the second output terminal b2 (for example, the switch 22 can be a double-pole double-throw switch), so that the electronic device 10 can simultaneously control the first feed source 121 and the second feed source 122 to work, and the first radiating segment 117 and the second radiating segment 118 can simultaneously support the first positioning signal and the second positioning signal. The electronic device 10 can achieve dual positioning signal positioning, and the positioning of the electronic device 10 is more accurate. For example, the first positioning signal can be a GPS-L1 frequency band signal, and the second positioning signal can be a GPS-L5 frequency band signal, so the electronic device 10 can achieve dual GPS positioning. For example, if the first positioning signal and the second positioning signal are each electrically connected to a positioning signal RF module, then the control switch can include two input terminals and two output terminals (e.g., the control switch is a double-pole double-throw switch, or two single-pole single-throw switches). The control switch can achieve electrical connection between one positioning signal RF module and the first radiating segment 117 through one input terminal and one output terminal, and can achieve electrical connection between another positioning signal RF module and the second radiating segment 118 through the other input terminal and the other output terminal. Thus, the first radiating segment 117 and the second radiating segment 118 can simultaneously support the first positioning signal and the second positioning signal, and the electronic device 10 can also achieve dual positioning signal positioning, making the positioning of the electronic device 10 more accurate. It should be noted that the embodiments of this application do not limit the specific manner in which the first feed source 121 and the second feed source 122 work simultaneously.

[0058] It is understandable that when the first radiator 110, under the excitation of the first feed source 121, also supports the transmission and reception of the first Wi-Fi signal (transmission and reception include both sending and receiving), such as Figure 7As shown, the electronic device 10 may further include a Wi-Fi signal RF module 25 and a frequency divider 26. The frequency divider 26, also known as a splitter or distributor, can divide a single signal into multiple signals and support the reverse process. In this case, the first feed source 121 may also include a Wi-Fi signal RF module 25 and a frequency divider 26. The Wi-Fi signal RF module 25 can be electrically connected to the frequency divider 26, and the frequency divider 26 can also be electrically connected to the first output terminal b1 of the switch 22. The frequency divider 26 can mix the positioning signal and the Wi-Fi signal transmitted through the switch 22 and transmit them to the first radiating segment 117, so that the first radiating segment 117 can simultaneously transmit the first positioning signal and the first Wi-Fi signal. The first positioning signal and the first Wi-Fi signal received by the first radiating segment 117 can also be transmitted to the positioning signal RF module 21 and the Wi-Fi signal RF module 25 respectively through the frequency divider 26, thereby realizing the reception of the first positioning signal and the first Wi-Fi signal. Taking a GPS-L1 frequency band signal as the first positioning signal and a 2.4G Wi-Fi signal as the first Wi-Fi signal as an example, in Figure 7 In the illustrated radio frequency architecture, the first radiating segment 117 can simultaneously support GPS-L1 band signals and 2.4G Wi-Fi signals. It should be noted that the first Wi-Fi signal can also be a Wi-Fi signal of other frequency bands, such as a 5G Wi-Fi signal, and this embodiment of the application does not limit this.

[0059] The electronic device 10 in this application embodiment can select the feed source corresponding to the stronger positioning signal among the first positioning signal and the second positioning signal. The electronic device 10 can perform positioning operations through the stronger positioning signal, and the positioning of the electronic device 10 is more accurate.

[0060] Please refer to the following: Figure 10 , Figure 10 This is a schematic diagram of a third structure of the electronic device 10 provided in an embodiment of this application. The electronic device 10 may also include a metal decorative element 140 and a third feed source 123.

[0061] The metal decorative element 140 can be disposed on the first body 200 or the second body 300. The metal decorative element 140 can be directly or indirectly electrically connected to the grounding plane 130 to achieve grounding. The third feed 123 can be electrically connected to the metal decorative element 140. The third feed 123 and the metal decorative element 140 can form a third positioning antenna. The third feed 123 can excite the metal decorative element 140 to support the third positioning signal.

[0062] It is understood that the third positioning signal can be, but is not limited to, GPS signals, BeiDou positioning signals, Galileo positioning signals, GLONASS positioning signals, etc. The third positioning signal can be a positioning signal in the same frequency band as the first or second positioning signal, or it can be a positioning signal in a different frequency band than the first and second positioning signals.

[0063] For example, when the first positioning signal and the second positioning signal are both positioning signals in the same frequency band, such as, but not limited to, GPS-L1 band signals, the third positioning signal can be a positioning signal in a different frequency band than the first and second positioning signals, such as, but not limited to, GPS-L5 band signals. In this case, the third positioning signal supported by the metal decorative part 140 can assist the first and second positioning signals in achieving positioning, thereby making the positioning of the electronic device 10 more accurate. In some embodiments, the electronic device 10 can acquire the signal strength of the first and second positioning signals, and the electronic device 10 can also control the feed source corresponding to the positioning signal with stronger signal strength among the first and second positioning signals to work; at this time, the electronic device 10 can control the third feed source 123 to be in working state, so that the electronic device 10 controls the first feed source 121 and the third feed source 123 to work simultaneously, or controls the second feed source 122 and the third feed source 123 to work simultaneously. In other embodiments, the electronic device also includes a proximity sensor that can detect the proximity state between the electronic device 10 and an object (e.g., a user's hand). The electronic device 10 can also control the first feed source 121 or the second feed source 122 to work according to the proximity state. At this time, the electronic device 10 can also control the third feed source 123 to work, so that the electronic device 10 controls the first feed source 121 and the third feed source 123 to work simultaneously, or controls the second feed source 122 and the third feed source 123 to work simultaneously.

[0064] For example, when one of the first and second positioning signals is a GPS-L1 band signal and the other is a GPS-L5 band signal, the third positioning signal supported by the metal decorative part 140 can be either a GPS-L1 band signal or a GPS-L5 band signal. In some embodiments, the electronic device 10 can control the third feed source 123 to select one signal from the GPS-L1 band signal and the GPS-L5 band signal based on the operating states of the first feed source 121 and the second feed source 122, so that the frequency band of the positioning signal supported by the metal decorative part 140 is different from the frequency band of the positioning signal supported by the feed sources operating in the first and second feed sources 121 and 122, so that the electronic device 10 can achieve dual GPS positioning. It should be noted that the first to third positioning signals can also be other positioning signals, which are not limited here.

[0065] It should be noted that the first positioning signal, the second positioning signal, and the third signal can also be positioning signals of the same frequency band. The electronic device can also control the first feed source 121, the second feed source 122, and the third feed source 123 to work simultaneously. The specific working mode of the three feed sources is not limited in the embodiments of this application.

[0066] It is understood that the metal decorative element 140 is often used to decorate the functional modules 600 of the electronic device 10 (e.g., but not limited to, the camera module and sensor module of the electronic device 10) to give the electronic device 10 a certain aesthetic appeal. The electronic device 10 may include a back cover 700, which can be connected to the mid-frame 400 to form a certain accommodating space. Through holes may be provided on the back cover 700, and the functional modules 600 of the electronic device 10 can be located within the accommodating space and collect signals from outside the electronic device 10 through these through holes. A portion of the metal decorative element 140 may be located inside the back cover 700, and another portion may be located on the outer surface of the back cover 700. The metal decorative element 140 may surround the functional modules. Of course, all of the metal decorative elements 140 may also be located on the outer surface of the back cover 700; this embodiment does not limit this.

[0067] It is understandable that when the electronic device 10 has a foldable structure, the back cover 700 of the electronic device 10 can also include two parts. For example, the back cover 700 includes a fifth part 710 and a sixth part 720. The first body 200 can include the fifth part 710 of the back cover 700, and the second body 300 can include the sixth part 720 of the back cover 700. The metal decorative piece 140 can be disposed on the back cover 700 of the first body 200. When the electronic device 10 is folded along the axis such that the second short frame 440 of the second body 300 overlaps with the first short frame 430 and both the first short frame 430 and the second short frame 440 are facing the sky and away from the ground, the fifth part 710 of the back cover 700 of the first body 200 is still opposite to the display surface of the electronic device 10. Furthermore, by Figure 4 and Figure 5 As shown, users generally do not easily grip the metal decorative piece 140, thus the user's grip is unlikely to affect the antenna performance of the metal decorative piece 140. The electronic device 10 has superior anti-grip performance when using the metal decorative piece 140 as a radiator. It should be noted that the metal decorative piece 140 can also be disposed in the sixth part 720 of the second body 300. The specific placement position of the metal decorative piece 140 is not limited in this embodiment.

[0068] It is understandable that when the third feed 123 is electrically connected to the metal decorative element 140, the third feed 123 can excite the metal decorative element 140 to support the third positioning signal, and the metal decorative element 140 can be reused as a radiating structure. To further improve the radiation performance of the metal decorative element 140 as a radiating structure, one or more (two or more) grounding points can be set in a suitable area of ​​the metal decorative element 140. The metal decorative element 140 can achieve grounding by electrically connecting more grounding points to the grounding plane 130. When the metal decorative element 140 supports the third positioning signal, less clutter is generated on the metal decorative element 140, and the antenna performance of the metal decorative element 140 supporting the third positioning signal is superior.

[0069] Understandably, in order to further reduce clutter on the metal trim 140, such as Figure 10 As shown, the electronic device 10 can also be equipped with one or more matching structures 150. One matching structure 150 can be electrically connected between the grounding point of the metal decorative part 140 and the grounding plane 130. By adjusting the matching structure 150 (also known as a matching circuit or matching network, which may include components such as capacitors and inductors), the clutter on the metal decorative part 140 is reduced. When the structure of the metal decorative part 140 is relatively regular and the electrical length meets the design requirements, the matching structure 150 can be a zero-ohm component to further improve the antenna performance of the metal decorative part 140.

[0070] In the electronic device 10 of this application embodiment, the first radiating segment 117 between the first end 111 and the first grounding point 113 on the first radiator 110 and the first feed 121 can form a first positioning antenna and support a first positioning signal. The second radiating segment 118 between the second end 116 and the second grounding point 114 and the second feed 122 can form a second positioning antenna and support a second positioning signal in the same frequency band as the first positioning signal. The metal decorative part 140 and the third feed 123 can form a third positioning antenna and support a third positioning signal in a different frequency band than the first positioning signal. The electronic device 10 can reuse the metal decorative part 140 as the radiating structure for the third positioning signal, and the electronic device 10 can achieve a miniaturized design. At the same time, the metal decorative part 140 and the first radiating segment 117 and the second radiating segment 118 disposed on the first short frame 430 can form a first positioning antenna and support a first positioning signal. With different settings, when the electronic device 10 is folded along the axis of the extension direction of the first short frame 430 (e.g., the second direction H2) so that the first short frame 430 of the first body 200 overlaps with the second short frame 440 of the second body 300, it is not easy for the user to hold the metal decorative piece 140, the first radiating segment 117 and the second radiating segment 118 at the same time when holding the electronic device 10. This allows the electronic device 10 of this application to still support at least two different positioning frequency bands of positioning signals when folded and held in the hand. Furthermore, the third positioning signal supported by the metal decorative piece 140 can assist the first positioning signal or the second positioning signal. Thus, the electronic device 10 of this application can achieve a miniaturized design and ensure good anti-grip performance of the electronic device 10 in the folded state, and the positioning performance of the electronic device is superior.

[0071] For the structure of the aforementioned electronic device 10, please refer to... Figure 11 , Figure 11 This is a schematic diagram of a fourth structure of the electronic device 10 provided in an embodiment of this application. The electronic device 10 also includes a second radiator 160 and a fourth feed source 124.

[0072] A portion of the second radiator 160 can be disposed on the first short frame 430, and another portion of the second radiator 160 can be disposed on the second long frame 420, for example, the third portion 421. One end of the second radiator 160 can be spaced apart from the second end 116 of the first radiator 110, and the other end of the second radiator 160 can extend in a direction away from the first radiator 110 and be electrically connected to the grounding plane 130 to achieve grounding. The fourth feed 124 can be directly or indirectly electrically connected to the second radiator 160, and the fourth feed 124 can excite the second radiator 160 to support the first wireless signal.

[0073] It is understood that the first wireless signal can be, but is not limited to, Wi-Fi, positioning, 3G, 4G, 5G, NFC, Bluetooth, UWB, etc. The first wireless signal can be a single type of wireless signal or multiple types of wireless signals. For example, the fourth feed 124 can excite the second radiator 160 to support at least one of mid-to-high frequency signals (1710MHz-2690MHz) and N78 band (3300MHz-3800MHz) wireless signals. When the second radiator 160 simultaneously supports both mid-to-high frequency signals and N78 band wireless signals, the excitation signal provided by the fourth feed 124 can excite the second radiator 160 to form two resonant current paths. One resonant current path can excite the second radiator 160 to support the transmission and reception of mid-to-high frequency signals, and the other resonant current path can excite the second radiator 160 to support the transmission and reception of N78 band wireless signals. Thus, the second radiator 160 can simultaneously achieve the transmission and reception of mid-to-high frequency signals and N78 band signals. The embodiments of this application do not specifically limit the first wireless signal.

[0074] It is understood that the fourth feed 124 can be electrically connected between the two ends of the second radiator 160, or it can be electrically connected to the end of the second radiator 160 closer to the first radiator 110. This embodiment does not limit this connection. Since the free ends of the second radiator 160 and the second radiating segment 118 of the first radiator 110 are opposite each other and a gap is formed between their free ends, and the grounded ends of the second radiator 160 and the second radiating segment 118 are far apart, the second radiator 160 and the second radiating segment 118 can form a one-to-one antenna structure. The second radiator 160 and the second radiating segment 118 are easily electromagnetically coupled. When the fourth feed 124 excites the second radiator 160 to support the first wireless signal, the fourth feed 124 can also excite the second radiator 160 and the second radiating segment 118 to jointly support the first wireless signal. This embodiment does not limit the specific excitation form of the first wireless signal.

[0075] It is understood that the first wireless signal may be different from the second positioning signal. For example, the first wireless signal and the second positioning signal may be wireless signals with significantly different frequencies. For instance, the first wireless signal may be a mid-to-high frequency wireless signal, and the second positioning signal may be a GPS-L1 band signal. In this case, the interference between the two wireless signals is relatively small. Of course, the first wireless signal and the second positioning signal may also be other wireless signals, and this application does not limit this.

[0076] To further reduce the interference of the first wireless signal on the second positioning signal, please refer again... Figure 11 The electronic device 10 may also include a matching circuit 170.

[0077] Matching circuit 170 can be directly or indirectly electrically connected between second feed source 122 and second feed point 115. Matching circuit 170 can allow the first resonant current formed when the second feed source 122 excites and generates the second positioning signal to pass through, and can be used to block the second resonant current formed when the fourth feed source 124 excites and generates the first wireless signal to pass through.

[0078] It is understood that when the second feed 122 excites the second radiating segment 118 to support the second positioning signal, a first resonant current can be generated on the second radiating segment 118. This first resonant current can flow through the second feed 122 to the second radiator 160 to form a resonant mode and enable the second radiating segment 118 to support the second positioning signal. The first resonant current can flow through the matching circuit 170 to the second radiating segment 118. When the fourth feed 124 excites the second radiator 160 to support the first wireless signal, the second resonant current generated on the second radiator 160 can be electromagnetically coupled to the second radiating segment 118 through the gap between the second radiating segment 118 and the second radiator 160 and flow on the second radiating segment 118. Since the matching circuit 170 can cut off the second resonant current, the second resonant current is not easy to flow into the second feed 122 through the matching circuit 170. Therefore, the second resonant current is not easy to interfere with the second feed 122. When the second radiator 160 supports the first wireless signal, the interference to the second radiating segment 118 supporting the second positioning signal is small. The antenna performance of the electronic device 10 that supports both the first wireless signal and the second positioning signal is better.

[0079] It is understood that the matching circuit 170 may include, but is not limited to, electronic components such as capacitors, inductors, and switches. For example, please refer to... Figure 11 Please refer to Figure 12 , Figure 12 for Figure 11 The diagram shows an electrical connection of the matching circuit 170. The matching circuit 170 may include a first inductor 171, a first capacitor 172, a second inductor 173, and a third inductor 174.

[0080] One end of the first inductor 171 can be directly or indirectly connected between the second feed source 122 and the second feed point 115. One end of the first capacitor 172 can be electrically connected to one end of the first inductor 171, and the other end of the first capacitor 172 is electrically connected to the ground plane 130 to achieve grounding. One end of the second inductor 173 is directly or indirectly connected between one end of the first inductor 171 and the second feed source 122, and the other end of the second inductor 173 is electrically connected to the ground plane 130 to achieve grounding. One end of the third inductor 174 is directly or indirectly connected to one end of the second inductor 173, and the other end of the third inductor 174 is electrically connected to the second feed source 122.

[0081] It is understood that the first inductor 171 and the first capacitor 172 can be connected in series, and the combined series connection can be connected in parallel with the second inductor 173 to form a new system. This new system can then be connected in series with the third inductor 174 between the second feed source 122 and the second feed point 115. The system formed by the first inductor 171, the first capacitor 172, and the second inductor 173 can filter out the second resonant current generated when the fourth feed source 124 excites and generates the first wireless signal. This allows the second resonant current to return to ground through the first inductor 171, the first capacitor 172, and the second inductor 173, making it difficult for the second resonant current to flow into the second feed source 122. Furthermore, the third inductor 174 can further block the second resonant current from flowing into the second feed source 122, thereby further cutting off the second resonant current.

[0082] It is understood that the inductance value of the first inductor 171 may be, but is not limited to, 2.7 nH (nanohenry), the capacitance value of the first capacitor 172 may be, but is not limited to, 2.2 pF (picofarad), the inductance value of the second inductor 173 may be, but is not limited to, 8.2 nH, and the inductance value of the third inductor 174 may be, but is not limited to, 10 nH. Of course, the parameter values ​​of the above-mentioned inductors and capacitors may also be other values, and this application embodiment does not limit them.

[0083] The electronic device 10 in this embodiment of the application prevents the second resonant current generated by the excitation of the fourth feed 124 from flowing into the second feed 122 through the matching circuit 170. The mutual interference between the second feed 122 and the fourth feed 124 is smaller, and the antenna performance of the electronic device 10 is better when it supports the second positioning signal and the first wireless signal at the same time.

[0084] Please refer to the following: Figure 13 , Figure 13 This is a fifth structural schematic diagram of the electronic device 10 provided in an embodiment of this application. The electronic device 10 may further include a third radiator 180 and a fifth feed source 125.

[0085] A portion of the third radiator 180 can be disposed on the first short frame 430, and another portion of the third radiator 180 can be disposed on the first long frame 410, for example, the first portion 411. The third radiator 180 can be disposed at the corner connecting the first short frame 430 and the first long frame 410. One end of the third radiator 180 can be spaced apart from the first end 111 of the first radiator 110, and the other end of the third radiator 180 can extend away from the first radiator 110 and be electrically connected to the grounding plane 130 to achieve grounding. The fifth feed 125 can be directly or indirectly electrically connected to the third radiator 180, and the fifth feed 125 is used to excite the third radiator 180 to support the second wireless signal.

[0086] It is understood that the second wireless signal can be, but is not limited to, a Wi-Fi signal, a positioning signal, a 3G signal, a 4G signal, a 5G signal, an NFC signal, a Bluetooth signal, a UWB signal, etc. The second wireless signal can be a single type of wireless signal or multiple types of wireless signals. For example, the second wireless signal can include at least one of a 5G Wi-Fi signal and an N78 band signal. When the third radiator 180 simultaneously supports both 5G Wi-Fi signals and N78 band signals, the excitation signal provided by the fifth feed source 125 can excite the third radiator 180 to form two resonant current paths. One resonant current path can excite the third radiator 180 to support the transmission and reception of 5G Wi-Fi signals, and the other resonant current path can excite the third radiator 180 to support the transmission and reception of N78 band wireless signals. Thus, the third radiator 180 can simultaneously achieve the transmission and reception of both 5G Wi-Fi signals and N78 band signals. This application embodiment does not specifically limit the second wireless signal.

[0087] It is understood that the fifth feed 125 can be electrically connected between the two ends of the third radiator 180, or the fifth feed 125 can be electrically connected to the end of the third radiator 180 near the first radiator 110. This application embodiment does not limit this.

[0088] The electronic device 10 of this application embodiment is provided with two positioning antennas on the first short frame 430. At the same time, a mid-to-high frequency antenna, an N78 band antenna and a 5G Wi-Fi antenna are provided on the first short frame 430 and the first long frame 410 and the second long frame 420 connected to the first short frame 430. The entire antenna architecture is compact and the interference between antennas is small. The electronic device 10 has better antenna performance.

[0089] For the structure of the aforementioned electronic device 10, please refer to... Figure 14 , Figure 14This is a sixth structural schematic diagram of the electronic device 10 provided in the embodiments of this application. The electronic device 10 in the embodiments of this application may further include a display screen, such as a flexible display screen 800, a circuit board 900, and a power supply 1000.

[0090] The display screen, such as a flexible display screen 800, can form the display surface of the electronic device 10 for displaying images, text, and other information. The flexible display screen 800 may include a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display screen. The display screen can be connected to the mid-frame 400; for example, one end of the flexible display screen 800 can be connected to the first body 200, and the other end can be connected to the second body 300. When the first body 200 and the second body 300 are in an unfolded state, the two ends of the flexible display screen 800 can be on the same plane as the first body 200 and the second body 300 unfold. When the first body 200 and the second body 300 are in an overlapping state, the flexible display screen 800 can fold as the first body 200 and the second body 300 are folded, so that the two ends of the flexible display screen 800 can be close to each other or completely close to each other and folded together.

[0091] It is understood that the flexible display screen 800 can serve as the main display screen of the electronic device 10.

The electronic device 10 may also include a secondary display screen, which can be disposed on the first body 200 or the second body 300. When the electronic device 10 is in a folded state, the electronic device 10 can display information through the secondary display screen. This application embodiment does not limit the display method of the electronic device 10.

[0092] The circuit board 900 can be mounted on the mid-frame 400. When the electronic device 10 has a folding structure, the circuit board 900 can be mounted on the first body 200 or the second body 300. The circuit board 900 can be the motherboard of the electronic device 10. The circuit board 900 can integrate a processor, and can also integrate one or more functional components such as a headphone jack, an accelerometer, a gyroscope, and a motor.

[0093] It is understood that the first feed source 121 to the fifth feed source 125 and the matching circuit 170 can be disposed on the circuit board 900 so that they can be controlled by the processor on the circuit board 900. Of course, the above structure can also be disposed on other carrier boards of the electronic device 10, and this application embodiment does not limit this.

[0094] The power supply 1000 can be mounted on the mid-frame 400, for example, on the first body 200 or the second body 300. Simultaneously, the power supply 1000 can be electrically connected to the circuit board 900 to power the electronic device 10. The circuit board 900 can be equipped with a power supply 1000 management circuit. This circuit distributes the voltage provided by the power supply 1000 to the various electronic components within the electronic device 10.

[0095] It is understood that the above are merely exemplary examples of the electronic device 10. The electronic device 10 in this application embodiment may also include components such as a camera, a sensor, and a sound-to-electric conversion device. These components can be found in the descriptions in related technologies and will not be repeated here.
