Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electronics, and particularly relates to an electronic device. BACKGROUND

[0002] With the continuous development of electronic technology, people have more and more functional needs for electronic devices, so more and more functions can be implemented on electronic devices, and therefore more and more types of antennas need to be provided on electronic devices. However, due to the large number of types of antennas provided, the setting space reserved for satellite communication antennas in electronic devices is small, which leads to small size of satellite communication antennas that can be provided in electronic devices, and thus easily leads to poor satellite communication performance of electronic devices. SUMMARY

[0003] The present application aims to provide an electronic device, which solves the problem of poor satellite communication performance of electronic devices.

[0004] In order to solve the above technical problems, the present application is implemented as follows:

[0005] The electronic device provided by the present application comprises a frame, a satellite communication module, a first cellular communication module, a second cellular communication module, and a grounding plate. The frame comprises a first frame part, a second frame part, and a third frame part arranged in sequence. The second frame part comprises a first radiator and a first grounding branch. The first radiator is located at the top of the frame. The first frame part and the first radiator have a first gap therebetween. The first grounding branch is connected with the grounding plate. The third frame part comprises a second radiator. The first grounding branch and the second radiator have a second gap therebetween. The first radiator can be switched between the first cellular communication module and the satellite communication module, so that the first radiator is electrically connected with the first cellular communication module or the satellite communication module. The second radiator is electrically connected with the second cellular communication module.

[0006] When the satellite communication module is in a working state, the first radiator works in a satellite working frequency band, and under the action of the first radiator, the second radiator is at least partially in a satellite working mode.

[0007] In the present application, when the satellite communication module is in a working state, the first radiator works in a satellite working frequency band, and under the action of the first radiator, the second radiator is at least partially in a satellite working mode. That is, the second radiator at least partially and the first radiator can act cooperatively. In this way, the second radiator is no longer used as a cellular antenna, that is, the second radiator at least partially can act cooperatively with the first radiator serving as a satellite communication antenna, thereby improving the performance of the satellite communication antenna.

[0008] In addition, when both the first cellular communication module and the second cellular communication module are in operation, the first radiator and the second radiator are isolated by the ground plane to obtain a high degree of isolation, which can ensure good isolation between the first radiator and the second radiator, thereby ensuring good cellular communication performance between the first radiator and the second radiator.

[0020] Embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are for the purpose of explanation only, and are not to be taken as limiting of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0021] The terms "first", "second" in the description and claims of the present application can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents that the front and rear associated objects are in a "or" relationship.

[0022] Referring to Figure 1 , Figure 1 A structural schematic diagram of an electronic device provided by an embodiment of the present application is shown in Figure 2 , Figure 2 A structural schematic diagram of an electronic device provided by an embodiment of the present application is shown in Figure 1 An enlarged view of the structure of region A in Figures 2-3 As shown in the drawings, the electronic device comprises a frame 10, a satellite communication module 20, a first cellular communication module 30, a second cellular communication module 40 and a ground plate 50, the frame 10 comprises a first frame part 11, a second frame part 12 and a third frame part 13 arranged in sequence, the second frame part 12 comprises a first radiator 120 and a first ground branch 121, the first radiator 120 is located at the top of the frame 10, the first frame part 11 and the first radiator 120 have a first gap 14 therebetween, the first ground branch 121 is connected with the ground plate 50, the third frame part 13 comprises a second radiator 130, the first ground branch 121 and the second radiator 130 have a second gap 15 therebetween, the first radiator 120 can be switched between the first cellular communication module 30 and the satellite communication module 20, so that the first radiator 120 is electrically connected with the first cellular communication module 30 or the satellite communication module 20, and the second radiator 130 is electrically connected with the second cellular communication module 40.

[0023] Wherein, when the satellite communication module 20 is in a working state, the first radiator 120 works in a satellite working frequency band, and under the action of the first radiator 120, the second radiator 130 is at least partially in a satellite working mode.

[0024] It should be noted that due to the first ground branch 121 between the first radiator 120 and the second radiator 130, it is difficult to couple or the coupling effect is poor between the first radiator 120 and the second radiator 130, so when the first radiator 120 works in the satellite working frequency band, the first radiator 120 can at least partially have an induction effect on the second radiator 130, so that the second radiator 130 at least partially appears an induced current, that is, the second radiator 130 at least partially works in a satellite mode, at this time, the first radiator 120 and the second radiator 130 at least partially can work cooperatively, thereby improving the satellite communication performance of the electronic device.

[0025] In addition, when the first cellular communication module 30 and the second cellular communication module 40 are both in the working state, since the ground plate 50 is connected with the first ground branch 121, and the first ground branch 121 is located between the first radiator 120 and the second radiator 130, the first ground branch 121 lengthens the distance between the first radiator 120 and the second radiator 130, thereby improving the isolation between the first radiator 120 and the second radiator 130.

[0026] The first radiator 120 is located at the top of the frame body 10, which can be understood as that the first radiator 120 is located on the frame body 10 close to the earpiece. Optionally, the second frame body 12 of the frame body 10 is provided with an earpiece hole, or the second frame body 12 is arranged close to the earpiece hole, and the fourth frame body of the frame body 10 is provided with a loudspeaker hole, so that the first radiator 120 needs to be arranged on the second frame body 12. The fourth frame body and the second frame body 12 can be arranged oppositely, that is, the fourth frame body is located at the bottom of the electronic device. In this way, when the satellite communication module of the electronic device is in the working state, the strongest direction of the radiation pattern of the first radiator 120 can be ensured to point to the sky.

[0027] The working principle of the embodiment of the present application can be understood as follows:

[0028] When the satellite communication module is in the working state, the first radiator 120 works in the satellite working frequency band, and under the action of the first radiator 120, the second radiator 130 at least partially works in a satellite mode, that is, the second radiator 130 at least partially and the first radiator 120 can work cooperatively. In this way, the second radiator 130 is no longer used as a cellular antenna, that is, the second radiator 130 at least partially can work cooperatively with the first radiator 120 serving as a satellite communication antenna, thereby improving the performance of the satellite communication antenna.

[0029] In addition, when the first cellular communication module 30 and the second cellular communication module 40 are both in the working state, the first radiator 120 and the second radiator 130 are isolated by the ground plate to obtain isolation, that is, the isolation between the first radiator 120 and the second radiator 130 can be better, so as to ensure that the cellular communication performance of the first radiator 120 and the second radiator 130 is better.

[0030] It should be noted that when the second radiator 130 is at least partially used in the satellite working mode, the second radiator 130 will at least partially generate induced current, thereby changing the current path and distribution on the electronic device; and the current distribution determines the directivity pattern of the satellite communication antenna, and changing the current path and distribution can change the directivity pattern of the satellite communication antenna, as shown in Figure 5 and 6 , Figure 5 is the directivity pattern of the antenna corresponding to the satellite communication module of the electronic device before the second radiator 130 at least partially works cooperatively with the first radiator 120, Figure 6 is the directivity pattern of the radiator corresponding to the satellite communication module of the electronic device after the second radiator 130 at least partially works cooperatively with the first radiator 120, in combination with Figure 5 and Figure 6 It can be known that the upper hemisphere ratio is increased from 52% to 67%, and the upper hemisphere performance of the satellite communication antenna is obviously improved, Figure 5 and Figure 6 The darker the color is, the better the directivity is.

[0031] It should be noted that when the satellite communication module 20 is in the working state, the first radiator 120 works in the satellite working frequency band, and the second radiator 130 can be in the satellite working mode entirely or partially. When part of the second radiator 130 is in the satellite working mode, the above-mentioned part of the second radiator 130 can be referred to as a target radiator. When the second cellular communication module 40 is electrically connected to the second radiator 130 through the second feeding structure 71, the target radiator can refer to a region on the second radiator 130 and between the second feeding structure 71 and the end of the second radiator 130 facing the first ground branch 121. Referring to Figure 2 , Figure 2 The length of the target radiator can be represented by C, and the length of the second radiator 130 can be represented by B.

[0032] Meanwhile, when the second radiator 130 at least partially cooperates with the first radiator 120, i.e. the satellite communication module 20 in the embodiment of the application can multiplex at least part of the first radiator 120 and the second radiator 130, the first radiator 120 can serve as a radiating antenna of the first cellular communication module 30, and the second radiator 130 can serve as a radiating antenna of the second cellular communication module 40, so that a radiator does not need to be separately arranged for the satellite communication module 20, thereby enhancing the radiating performance of the electronic device, reducing the number of radiators and the arrangement space of the radiators on the electronic device, and further reducing the volume of the electronic device.

[0033] The working frequency bands of the first cellular communication module 30 and the second cellular communication module 40 can be the same, so as to enhance the radiating performance of the electronic device, or the working frequency bands of the first cellular communication module 30 and the second cellular communication module 40 can also be different, so as to increase the bandwidth of the radiators of the electronic device.

[0034] The specific width of the first gap 14 and the second gap 15 is not limited herein, and the width of the first gap 14 and the second gap 15 can be the same or different.

[0035] As an optional embodiment, referring to Figure 2 The ground plate 50 comprises a first connecting portion 51, a second connecting portion 52 and a third connecting portion 53 which are connected to each other, the first connecting portion 51 is connected to the second connecting portion 52 through the third connecting portion 53, a first clearance area 60 is arranged between the first connecting portion 51 and the first radiator 120, a second clearance area 61 is arranged between the second connecting portion 52 and the second radiator 130, and the first clearance area 60 and the second clearance area 61 are respectively located on two sides of the third connecting portion 53.

[0036] The first connecting portion 51, the second connecting portion 52 and the third connecting portion 53 can be an integral molding structure, i.e. the ground plate 50 can be an integral ground plate, and the third connecting portion 53 can be electrically connected to the first ground branch 121, so that the third connecting portion 53 can provide isolation between the first radiator 120 and the second radiator 130 when the first cellular communication module 30 and the second cellular communication module 40 are both in the working state, thereby bettering the isolation between the first radiator 120 and the second radiator 130.

[0037] The first clearance area 60 can be understood as a non-metallic area between the first connecting portion 51 and the first radiator 120, and the second clearance area 61 can be understood as a non-metallic area between the second connecting portion 52 and the second radiator 130.

[0038] It should be noted that the size of the third connecting portion 53 can be determined according to the isolation requirement between the first radiator 120 and the second radiator 130.

[0039] In the embodiments of the present application, the first clearance area 60 and the second clearance area 61 are respectively located on the two sides of the third connecting portion 53, that is, the third connecting portion 53 can play a role of separating the first clearance area 60 and the second clearance area 61. When the first radiator 120 and the second radiator 130 are both used as cellular antennas, that is, the first cellular communication module 30 and the second cellular communication module 40 are in the working state, the isolation between the first radiator 120 and the second radiator 130 can be ensured to be good through the third connecting portion 53, so that the coupling degree between the first radiator 120 and the second radiator 130 can be reduced, and the mutual influence between the first radiator 120 and the second radiator 130 can be reduced.

[0040] As an optional embodiment, the first radiator 120 is located at the corner of the frame body 10, and the third frame portion 13 and the first frame portion 11 are respectively located on the two sides of the first radiator 120.

[0041] In the embodiments of the present application, when the satellite communication module 20 is in the working state, the first radiator 120 and the second radiator 130 can be made to work at least partially cooperatively, and the strongest direction of the radiation pattern of the antenna corresponding to the satellite communication module 20 can be made to point to the sky, so that the satellite is connected to establish, and the performance of the satellite communication function of the electronic device is enhanced.

[0042] As an optional embodiment, when the satellite communication module 20 is in the working state, the length of the radiator portion in the satellite working mode in the second radiator 130 and the length of the first radiator 120 are approximately equal. In this way, the cooperative working effect of the part of the second radiator 130 in the satellite working mode and the first radiator 120 can be better.

[0043] In the embodiments of the present application, when the satellite communication module 20 is in the working state, the length of the radiator portion in the satellite working mode in the second radiator 130 and the length of the first radiator 120 are approximately equal. In this way, the cooperative working effect of the part of the second radiator 130 in the satellite working mode and the first radiator 120 can be better.

[0044] As an optional embodiment, referring to Figure 2 、 Figure 7 、 Figure 8 andFigure 9 The first cellular communication module 30 or the satellite communication module 20 is electrically connected to the first radiator 120 through the first feeding structure 70, and the second cellular communication module 40 is electrically connected to the second radiator 130 through the second feeding structure 71. The length between the connection point of the second feeding structure 71 and the second radiator 130 and the first end of the third frame portion 13 is the first length, and the first end is the end facing the second frame portion 12.

[0045] In this embodiment of the application, by setting the first power supply structure 70 and the second power supply structure 71, the power supply to the first radiator 120 and the second radiator 130 can be made more stable and the power supply effect more reliable.

[0046] It should be noted that the connection positions of the first feed structure 70 and the second feed structure 71 with the first radiator 120 and the second radiator 130 are not limited here. By changing the connection positions of the first feed structure 70 with the first radiator 120 and the second feed structure 71 with the second radiator 130, the operating frequency bands of the first radiator 120 and the second radiator 130 can be changed.

[0047] Among them, see Figure 2 , Figure 7 , Figure 8 and Figure 9 , Figure 2 , Figure 7 , Figure 8 and Figure 9 The C in the text can be used to represent the first length mentioned above. Figure 2 , Figure 7 , Figure 8 and Figure 9 The letter B can be used to represent the length of the second radiator 130 mentioned above.

[0048] In this embodiment of the application, changing the position of the connection point of the second radiator 130 of the second feed structure 71 can change the first length, and changing the first length can change the operating frequency band of the second radiator 130. Thus, by adjusting the position of the connection point of the second radiator 130 of the second feed structure 71, the operating frequency band of the second radiator 130 can be adjusted, thereby enhancing the flexibility of the adjustment method of the operating frequency band of the second radiator 130.

[0049] As an optional implementation, the length of the first radiator 120 and the first length are both one-quarter of λ1, where λ1 is the operating wavelength corresponding to the first target communication frequency of the first cellular communication module 30.

[0050] The working wavelength can be understood as a working wavelength of the first target communication frequency in an environment where the electronic device is located.

[0051] In this way, the working frequency bands of the first radiator 120 and the second radiator 130 can be ensured to be wide, and the working performance of the first radiator 120 and the second radiator 130 is good.

[0052] As an optional implementation, the first target communication frequency is located in 1.7 GHz-2.7 GHz, the length of the second radiator 130 is one quarter of λ2, and λ2 is a working wavelength corresponding to a second target communication frequency of the second cellular communication module 40. The second target communication frequency is located in 0.5 GHz-1 GHz. In this way, the radiation performance of the second radiator 130 is good.

[0053] As an optional implementation, referring to Figure 3 The electronic device further includes at least two first matching circuits 80 and at least two second matching circuits 81. The first radiator 120 is electrically connected to the first cellular communication module 30 and the satellite communication module 20 through a first target matching circuit. The second radiator 130 is electrically connected to the second cellular communication module 40 through a second target matching circuit. The first target matching circuit is any one of the at least two first matching circuits 80. The parameters of any two of the at least two first matching circuits 80 are different, and the working frequency band of the first radiator 120 is different when the first radiator 120 is electrically connected to different first matching circuits 80. The parameters of any two of the at least two second matching circuits 81 are different, and the working frequency band of the second radiator 130 is different when the second radiator 130 is electrically connected to different second matching circuits 81.

[0054] The parameters of the first matching circuit 80 and the parameters of the second matching circuit 81 can refer to the types of electronic components included in the first matching circuit 80 and the second matching circuit 81 and the specifications of the electronic components. Optionally, the electronic components can include at least one of a capacitor, an inductor, and a resistor, and the specific specifications of the electronic components are not limited.

[0055] In the embodiment, the first radiator 120 is electrically connected with the first cellular communication module 30 and the satellite communication module 20 through the first target matching circuit, the parameters of any two first matching circuits 80 of the at least two first matching circuits 80 are different, and the working frequency band of the first radiator 120 is different when the first radiator 120 is electrically connected with different first matching circuits 80; the second radiator 130 is electrically connected with the second cellular communication module 40 through the second target matching circuit, the parameters of any two second matching circuits 81 of the at least two second matching circuits 81 are different, and the working frequency band of the second radiator 130 is different when the second radiator 130 is electrically connected with different second matching circuits 81. In this way, by controlling different first target matching circuits to be electrically connected with the first radiator 120 and by controlling different second target matching circuits to be electrically connected with the second radiator 130, the working frequency bands of the first radiator 120 and the second radiator 130 can be adjusted, that is, the adjustment mode of the working frequency bands of the first radiator 120 and the second radiator 130 is relatively flexible, and the adjustment efficiency is relatively high.

[0056] As an optional embodiment, referring to Figure 3 , the electronic device further includes a first switch 82, a second switch 83, a third switch 84, at least two first matching circuits 80, and at least two second matching circuits 81. The first radiator 120 is electrically connected with one first matching circuit 80 of the at least two first matching circuits 80 through the first switch 82, and the first radiator 120 is electrically connected with the first cellular communication module 30 or the satellite communication module 20 through the second switch 83. The second radiator 130 is electrically connected with one second matching circuit 81 of the at least two second matching circuits 81 through the third switch 84.

[0057] In the embodiment, by switching of the first switch 82, the first radiator 120 can be connected with different first matching circuits 80, so that the working frequency band of the first radiator 120 can be adjusted. By switching of the third switch 84, the second radiator 130 can be connected with different second matching circuits 81, so that the working frequency band of the second radiator 130 can be adjusted. In this way, the flexibility of the adjustment mode of the working frequency bands of the first radiator 120 and the second radiator 130 is further enhanced, and the adjustment efficiency is improved.

[0058] Optionally, by the first switch 82 and the third switch 84, the first radiator 120 can work in the B1, B3, B40, B41, or satellite communication frequency band, the second radiator 130 can work in the B5, B8, B28, B1, B3, B40, B41, or the like, or the switch can be connected with a matching device such as an inductor or directly connected with the ground plate 50, so that the first radiator 120 and the second radiator 130 can work in the B1, B3, B40, B41, B5, B8, B28, or the like.Figure 2 The electrical length of segment C shown is close to the electrical length of the first radiator 120. When the first radiator 120 is working in the satellite frequency band, it can improve the performance. The switch mentioned above can be the first switch 82 or the third switch 84.

[0059] As an optional implementation, see [link to implementation details]. Figure 3 The electronic device further includes a fourth switch 85. The satellite communication module 20 includes an uplink communication module 21 and a downlink communication module 22. The second switch 83 is electrically connected to the uplink communication module 21 or the downlink communication module 22 through the fourth switch 85.

[0060] In this embodiment, the first radiator 120 can be switched to be electrically connected to the uplink communication module 21 or the downlink communication module 22 by the second switch 83 and the fourth switch 85. When the first radiator 120 is electrically connected to the uplink communication module 21, the first radiator 120 can be in the uplink signal transmission mode of the satellite communication mode. When the first radiator 120 is electrically connected to the downlink communication module, the first radiator 120 can be in the downlink signal transmission mode of the satellite communication mode. In this way, the switching effect of the working mode of the first radiator 120 can be further enhanced.

[0061] As an optional implementation, the first frame portion 11 includes a third radiator 110, which is spaced apart from the first radiator 120 through the first gap 14. When the satellite communication module 20 is in operation, the third radiator 110 is coupled to the first radiator 120.

[0062] Among them, see Figure 7 and Figure 8 , Figure 7 and Figure 8 The length of the third radiator 110 can be represented by E, see [reference]. Figure 8 , Figure 8 The length of the first frame part 11 can be represented by F.

[0063] In this embodiment, since the first frame portion 11 also includes a third radiator 110, and when the satellite communication module 20 is in working state, the third radiator 110 is coupled to the first radiator 120, thereby further enhancing the length of the radiator and enhancing the radiation performance of the electronic device, that is, enhancing the performance of the satellite communication function of the electronic device.

[0064] As an optional implementation, the length of the third radiator 110 is L4, and λ1 / 16≤L4≤3λ1 / 16, where λ1 is the working wavelength corresponding to the first target communication frequency of the satellite communication module 20, and the first target communication frequency is within 1.7GHz-2.7GHz.

[0065] The working wavelength corresponding to the first target communication frequency can be understood as the working wavelength corresponding to the first target communication frequency in the environment where the electronic device is located.

[0066] In the embodiments of the present application, the length of the third radiator 110 is L4, so as to ensure that the working frequency bands of the first radiator 120 and the third radiator 110 are wide, that is, the bandwidths of the first radiator 120 and the third radiator 110 are enhanced.

[0068] The third clearance area 62 can be understood as a non-metal area between the first frame part 11 and the first connecting part 51.

[0069] Referring to Figure 8 and Figure 7 , the length L4 can be expressed by E in Figure 8 and Figure 9 .

[0070] The UWB communication module can be used for positioning and ranging, so that the electronic device has the functions of unlocking, locking, and welcoming, etc.

[0071] In the embodiments of the present application, the first frame part 11 and the first connecting part 51 are provided with the third clearance area 62, that is, the first connecting part 51 is not directly electrically connected with the first frame part 11, so as to enhance the performance of the third radiator 110.
