Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, and more specifically to an electronic device. Background Technology

[0002] With the development of technology, foldable electronic devices are becoming increasingly widely used. These devices can include two screens; when unfolded, they can be combined into one screen; when folded, they can remain as two independent screens. However, when the foldable device is folded and the antennas corresponding to the two screens are operating on the same frequency, the antennas located on the two screens will interfere with each other. Summary of the Invention

[0003] This invention provides an electronic device to solve the problem in related technologies where two antennas working at the same frequency in a folded state can interfere with each other.

[0004] To solve the above-mentioned technical problems, the present invention is implemented as follows:

[0005] This invention provides an electronic device, which includes: a first housing, a second housing, and a rotating assembly;

[0006] The first housing and the second housing are movably connected by the rotating assembly to make the electronic device foldable; a first antenna is provided on the first housing, a second antenna is provided on the second housing, and at least a portion of the projection area of ​​the second antenna and the first antenna on the second housing coincides;

[0007] When the electronic device is in a folded state and the operating frequency band of the first antenna is the same as that of the second antenna, the first antenna is in a first operating state and the second antenna is in a second operating state, and the current flow direction in the first antenna is opposite to that in the second antenna.

[0008] In this embodiment of the invention, the electronic device includes a first housing, a second housing, and a rotating assembly. The first housing and the second housing are rotatable relative to the rotating assembly, thereby allowing the electronic device to switch between a folded state and an unfolded state. Since a first antenna is disposed on the first housing and a second antenna is disposed on the second housing, and at least a portion of the projection area of ​​the second antenna on the second housing coincides with that of the first antenna, when the electronic device is in the folded state and the operating frequency bands of the first antenna and the second antenna are the same, the first antenna can be controlled to be in a first operating state and the second antenna to be in a second operating state. The current flow directions in the first antenna in the first operating state and the second antenna in the second operating state are opposite, thereby avoiding mutual interference between the first antenna and the second antenna and ensuring high isolation performance between them at the same frequency.

Figures 1 to 11 As shown, the electronic device 100 includes: a first housing 10, a second housing 20, and a rotating assembly 30; the first housing 10 and the second housing 20 are movably connected by the rotating assembly 30 so that the electronic device 100 is foldable; a first antenna 12 is provided on the first housing 10, and a second antenna 22 is provided on the second housing 20, and the second antenna 22 and at least a portion of the projection area of ​​the first antenna 12 on the second housing 20 coincide; when the electronic device 100 is in a folded state, and the operating frequency band of the first antenna 12 is the same as the operating frequency band of the second antenna 22, the first antenna 12 is in a first operating state, the second antenna 22 is in a second operating state, and the current flow direction in the first antenna 12 is opposite to the current flow direction in the second antenna 22.

[0025] In this embodiment of the invention, the electronic device 100 includes a first housing 10, a second housing 20, and a rotating assembly 30. The first housing 10 and the second housing 20 are rotatable relative to the rotating assembly 30, thereby allowing the electronic device 100 to switch between a folded state and an unfolded state. Since a first antenna 12 is disposed on the first housing 10 and a second antenna 22 is disposed on the second housing 20, and at least a portion of the projection area of ​​the second antenna 22 on the second housing 20 overlaps with that of the first antenna 12, when the electronic device 100 is in a folded state and the operating frequency bands of the first antenna 12 and the second antenna 22 are the same, the first antenna 12 can be controlled to be in a first operating state and the second antenna 22 to be in a second operating state. The current flow directions in the first antenna 12 in the first operating state and the second antenna 22 in the second operating state are opposite, thereby preventing mutual interference between the first antenna 12 and the second antenna 22 and ensuring high isolation performance between them at the same frequency.

[0026] It should be noted that the first and second outer shells can rotate relative to the rotating assembly 30, allowing the electronic device 100 to be in a folded or unfolded state, such as... Figure 2 As shown, Figure 2The median angle α is the angle between the first outer shell and the second outer shell. The electronic device 100 can be folded inwards or outwards. When the electronic device 100 is folded and the display screen is on the inside, i.e., when the outer shell is observable, this folding method is inward folding, such as... Figure 3 As shown, when the folded display screen is on the outside, i.e., when the screen is observable, this folding method is called outward folding, as... Figure 4 As shown. This embodiment of the invention does not specifically limit the folding state of the electronic device 100.

[0027] It should also be noted that the first screen 11 is disposed on the first housing, the second screen 21 is disposed on the second housing, the first antenna 12 can be located in any area of ​​the non-screen region between the first housing and the first screen 11, and the corresponding second antenna 22 can be located in any area of ​​the non-screen region between the second housing and the second screen 21, and there is an overlapping area between the second antenna 22 and the first antenna 12. Figure 1 The diagram shows the positions of the first antenna 12 and the second antenna 22.

[0028] In some embodiments, the first antenna 12 may include a first radiating structure 121 and a first feeding module 122, with the first radiating structure 121 connected to the first feeding module 122. The second antenna 22 may include a second radiating structure 221 and a second feeding module 222, with the second radiating structure 221 connected to the second feeding module 222. The second feeding module 222 includes a phase control module 229. When the electronic device 100 is in a folded state, the phase control module 229 controls the phase difference between the two feeding signals entering the second radiating structure 221 to be 180°, so that the current flow direction in the second antenna 22 is opposite to the current flow direction in the first antenna 12.

[0029] The first antenna 12 includes a first radiating structure 121 and a first feeding module 122, which are connected. The second antenna 22 includes a second radiating structure 221 and a second feeding module 222, which are connected. Thus, a feeding signal can be fed to the first antenna 12 through the first feeding module 122 and to the second antenna 22 through the second feeding module 222, enabling the first antenna 12 and the second antenna 22 to operate normally.

[0030] The second feeding module 222 includes a phase control module 229, which controls the phase of the feeding signal in the second feeding module 222, ensuring that the phase difference between the two feeding signals fed into the second radiating structure 221 by the second feeding module 222 is 180°. This results in the current in the second antenna 22 flowing in the opposite direction to the current in the first antenna 12. Because the current in the second antenna 22 flows in the opposite direction to the current in the first antenna 12, when the first antenna 12 and the second antenna 22 operate in the same frequency band, mutual interference between the first antenna 12 and the second antenna 22 can be avoided, improving the inter-band isolation between the two antennas in the folded state of the electronic device 100.

[0031] Additionally, in some embodiments, such as Figure 5 As shown, the first power supply module 122 includes a first excitation source 126, a first switch, and a first matching circuit 127. The first switch includes a first sub-switch 1281, a second sub-switch 1282, and a third sub-switch 1283. The first sub-switch 1281 is connected to the first contact point of the first radiating structure 121. One end of the second sub-switch 1282 is connected to the second and third contact points of the first radiating structure 121, respectively, and the other end of the second sub-switch 1282 is grounded. The third sub-switch 1283 is connected to the fourth contact point of the first radiating structure 121. One end of the first matching circuit 127 is connected to the first excitation source 126, and the other end of the first matching circuit 127 is connected to the first sub-switch 1281 and the third sub-switch 1283.

[0032] The first power supply module 122 includes a first excitation source 126, a first switch, and a first matching circuit 127. The first switch includes a first sub-switch 1281, a second sub-switch 1282, and a third sub-switch 1283. One end of the first matching circuit 127 is connected to the first excitation source 126, and the other end of the first matching circuit 127 is connected to the first sub-switch 1281 and the second sub-switch 1282. The first sub-switch 1281 is connected to a first contact point on the first radiating structure 121, the third sub-switch 1283 is connected to a fourth contact point on the first radiating structure 121, and one end of the second sub-switch 1282 is connected to a second and a third contact point on the first radiating structure 121, while the other end of the second sub-switch 1282 is grounded. Therefore, by controlling the opening and closing of the first sub-switch 1281, the second sub-switch 1282, and the third sub-switch 1283, the connection method between the first matching circuit 127 and the first radiating structure 121 can be different. That is, by controlling the first switch to be in different states, the connection between the first power supply module 122 and the first radiation structure 121 can be changed, so that the first antenna 12 can be in different modes.

[0033] It should be noted that the first switch can also be a single-pole multi-throw switch. By controlling the single-pole multi-throw switch, different lines can be in a conducting state, so that the first power supply module 122 is in different states.

[0034] Additionally, in some embodiments, such as Figure 5 As shown, a first slit 123 may be provided on the first housing 10, which divides the first housing 10 into a first branch 124 and a second branch 125. Both the first branch 124 and the second branch 125 are grounded. The first slit 123, the first branch 124, and the second branch 125 form a first radial structure 121. The first contact point and the third contact point are both located on the first branch 124, and the second contact point and the fourth contact point are both located on the second branch 125.

[0035] A first slit 123 is provided on the first housing 10, dividing the first housing 10 into a first branch 124 and a second branch 125. Both the first branch 124 and the second branch 125 are grounded, thus forming a first radial structure 121. Since the first contact point and the third contact point are located on the first branch 124, and the second contact point and the fourth contact point are located on the second branch 125, that is, the first sub-switch 1281 is connected to the first branch 124, the third sub-switch 1283 is connected to the second branch 125, and one end of the second sub-switch 1282 is connected to both the first branch 124 and the second branch 125, the second radial structure 221 and the second power supply module 222 can be connected.

[0036] Additionally, in some embodiments, such as Figure 6 As shown, the second power supply module 222 may further include a second excitation source 226, a second switch 228, and a second matching circuit 227. The phase control module 229 includes a first phase control module 2291 and a second phase control module 2292. The first phase control module 2291 is connected to the second phase control module 2292. One end of the second matching circuit 227 is connected to the second excitation source 226, and the other end of the second matching circuit 227 is connected to both the first phase control module 2291 and the second phase control module 2292. 291 is connected to the fifth contact point of the second radiating structure 221, the second phase control module 2292 is connected to the sixth contact point of the second radiating structure 221, and the second switch 228 is connected between the second phase control module 2292 and the second matching circuit 227. When the second switch 228 is closed, the first phase control module 2291 and the second phase control module 2292 work, and the first phase control module 2291 and the second phase control module 2292 control the phase difference of the two feed signals entering the second radiating structure 221 to be 180°.

[0037] The second power supply module 222 includes a second excitation source 226, a second switch 228, a second matching circuit 227, and a phase control module 229. One end of the second matching circuit 227 is connected to the second excitation source 226, and the other end of the second matching circuit 227 is connected to the first phase control module 2291 and the second phase control module 2292. The first phase control module 2291 is connected to the fifth contact point on the second radiating structure 221, and the second phase control module 2292 is connected to the sixth contact point on the second radiating structure 221. The second switch 228 is located between the second matching circuit 227 and the second phase control module 2292. Therefore, by controlling the opening and closing of the second switch 228, a short circuit or connection can be formed between the second phase control module 2292 and the second radiating structure 221, so that the second antenna 22 can be in different modes.

[0038] It should be noted that the first phase control module 2291 and the second phase control module 2292 are connected, so that the first phase control module 2291 and the second phase control module 2292 can be used as a whole to control the phase difference of the two feed signals. Of course, the first phase control module 2291 and the second phase control module 2292 can also be disconnected, that is, the first phase control module 2291 and the second phase control module 2292 can be independent of each other. The first phase control module 2291 controls the phase of one feed signal, and the second phase control module 2292 controls the phase of the other feed signal, so that the phase difference of the two feed signals meets the condition.

[0039] Additionally, in some embodiments, such as Figure 6 As shown, a second slit 223 may be provided on the second housing 20, which divides the second housing 20 into a third branch 224 and a fourth branch 225. Both the third branch 224 and the fourth branch 225 are grounded. The second slit 223, the third branch 224, and the fourth branch 225 form a second radial structure 221. The fifth contact point is located on the third branch 224, and the sixth contact point is located on the fourth branch 225.

[0040] The second housing 20 is provided with a second slit 223, which divides the second housing 20 into a third branch 224 and a fourth branch 225. Both the third branch 224 and the fourth branch 225 are grounded, thus forming a second radial structure 221. Since the fifth contact point is located on the third branch 224 and the sixth contact point is located on the fourth branch 225, that is, the first phase control module 2291 is connected to the third branch 224 and the second phase control module 2292 is connected to the fourth branch 225, the connection between the second radial structure 221 and the second power supply module 222 can be realized.

[0041] Furthermore, the first housing 10 and the second housing 20 can be metal housings, such as magnesium alloys, stainless steel, or other metals. It should be noted that the materials of the housings in this embodiment are not limited to these; other materials can also be used, such as plastic housings, ceramic housings, and so on.

[0042] It should be noted that when the first housing 10 and the second housing 20 are metal housings, the first housing 10 can serve as the first radiating structure 121, and the second housing 20 can serve as the second radiating structure 221. That is, as described in this application, the first housing 10 is provided with a first slit 123, which divides the first housing 10 into a first branch 124 and a second branch 125, and the second housing 20 is provided with a second slit 223, which divides the second housing 20 into a third branch 224 and a fourth branch 225. In other words, when the first housing 10 and the second housing 20 are metal housings, the first housing 10 and the second housing 20 can serve as the radiating structure of an antenna.

[0043] When the first housing 10 and the second housing 20 are non-metallic housings, the first radiating structure 121 can be formed by a radiating metal disposed in a certain region within the first housing 10, and the second radiating structure 221 can be formed by a radiating metal disposed in a corresponding region within the second housing 20, wherein the region within the first housing 10 and the corresponding region within the second housing 20 overlap. Of course, when the first housing 10 and the second housing 20 are metallic housings, the first radiating structure 121 can also be formed by a radiating metal disposed in a certain region within the first housing 10, and the second radiating structure 221 can also be formed by a radiating metal disposed in a corresponding region within the second housing 20. The embodiments of the present invention do not specifically limit the specific forms of the first radiating structure 121 and the second radiating structure 221.

[0044] In addition, in some embodiments, when the electronic device 100 is in a folded state, the first sub-switch 1281 and the third sub-switch 1283 can be closed, and the second sub-switch 1282 can be opened, so that the first antenna 12 is in a first working state; and the second switch 228 can be closed, the first phase control module 2291 and the second phase control module 2292 are in a working state, and the first phase control module 2291 and the second phase control module 2292 control the phase difference between the feed signal entering the third branch 224 and the feed signal entering the fourth branch 225 to be 180°, so that the second antenna 22 is in a second working state.

[0045] With the first sub-switch 1281 and the third sub-switch 1283 closed, and the second sub-switch 1282 open, the first matching circuit 127 is connected to both the first stub 124 and the second stub 125. The second sub-switch 1282 is disconnected from the second contact point. The first antenna 12 forms a slot antenna and is in half-wave mode. At this time, the first antenna 12 is in its first operating state, and the current flows in opposite directions in the first stub 124 and the second stub 125. (Refer to...) Figure 8 , Figure 8 The direction of the middle arrow indicates the direction of the current. In the first stub 124, the current flows to the left relative to the first gap 123, and in the second stub 125, the current flows to the right relative to the first gap 123. That is, when the first antenna 12 is in the first operating state, the first antenna 12 constitutes a slot antenna and is in half-wave mode, and the currents in the first stub 124 and the second stub 125 are in opposite directions.

[0046] With the second switch 228 closed, the second matching circuit 227 is connected to the third stub 224 and the fourth stub 225. The feed signal from the second excitation source 226 is fed into the third stub 224 and the fourth stub 225 respectively via two paths. The first phase control module 2291 and the second phase control module 2292 can control the phase difference between the two feed signals to meet 180°. At this time, the second antenna 22 is in the second operating state, forming a slot antenna, and is in half-wave mode. The current flow direction in the third stub 224 is the same as that in the fourth stub 225. Figure 10 , Figure 10 The direction of the middle arrow indicates the current direction. The current in the third stub 224 flows to the right relative to the second slot 223, and the current in the fourth stub 225 also flows to the right relative to the second slot 223. That is, when the second antenna 22 is in the second operating state, the second antenna 22 constitutes a slot antenna and is in half-wave mode, and the currents in the third stub 224 and the fourth stub 225 are in the same direction.

[0047] When the electronic device 100 is in a folded state, the first sub-switch 1281 and the third sub-switch 1283 are closed, the second sub-switch 1282 is open, and the second switch 228 is closed, causing the first antenna 12 to be in a first operating state and the second antenna 22 to be in a second operating state. The currents in the first operating state of the first antenna 12 and the second operating state of the second antenna 22 are opposite, and the modes are naturally orthogonal, which can avoid interference between the first antenna 12 and the second antenna 22.

[0048] In some embodiments, when the electronic device 100 is in the unfolded state, the second sub-switch 1282 can be opened, the first sub-switch 1281 or the third sub-switch 1283 can be closed, the first antenna 12 is an IFA antenna, and the first antenna 12 is in half-wave mode; or, the first sub-switch 1281 and the third sub-switch 1283 can both be closed, the second sub-switch 1282 can be opened, the first antenna 12 is a slot antenna, and the antenna mode of the first antenna 12 is half-wave mode; or, the first sub-switch 1281, the second sub-switch 1282 and the third sub-switch 1283 can all be closed, and the first antenna 12 is in full-wave mode.

[0049] When the electronic device 100 is in the deployed state, the first antenna 12 has three operating states, namely state one, state two and state three, and the first antenna 12 can operate in any of the three states.

[0050] When the second sub-switch 1282 is open and the first sub-switch 1281 or the third sub-switch 1283 is closed, the first antenna 12 is in state one. At this time, the first antenna 12 constitutes an IFA antenna (inverted F antenna), as shown in the reference. Figure 7 The diagram shows a simplified antenna mode diagram when the first antenna 12 is in state one, at which time the first antenna 12 is in half-wave mode.

[0051] With the first sub-switch 1281 and the third sub-switch 1283 both closed, and the second sub-switch 1282 open, the first antenna 12 is in state two, i.e., the first operating state of the first antenna 12. At this time, the first antenna 12 constitutes a slot antenna and is in half-wave mode, with the currents in the first stub 124 and the second stub 125 reversed. (Refer to...) Figure 8 The diagram shows a simplified antenna mode diagram when the first antenna 12 is in state two.

[0052] With the first sub-switch 1281, the second sub-switch 1282, and the third sub-switch 1283 all closed, the first antenna 12 is in state three. At this time, the first antenna 12 is a loop antenna and is in full-wave mode. (Refer to...) Figure 9 The diagram shows a simplified antenna mode diagram when the first antenna 12 is in state three.

[0053] In some embodiments, when the electronic device 100 is in the deployed state, the second switch 228 can be closed, and the first phase control module 2291 and the second phase control module 2292 control the phase difference between the current entering the third stub 224 and the feed signal entering the fourth stub 225 to be 180°, and the second antenna 22 is a slot antenna and is in half-wave mode; or, the second switch 228 can be opened, the second antenna 22 is an IFA antenna and is in half-wave mode.

[0054] When the electronic device 100 is in the deployed state, the second antenna 22 has two working states, namely state four and state five, and the second antenna 22 can work in either of the two states.

[0055] With the second switch 228 closed, the second antenna 22 is in state four, i.e., the second operating state of the second antenna 22. At this time, the second antenna 22 constitutes a slot antenna and is in half-wave mode, with the currents in the second stub 125 and the fourth stub 225 flowing in the same direction. (Refer to...) Figure 10 The diagram shows a simplified antenna pattern when antenna 22 is in state four.

[0056] With the second switch 228 open, the second antenna 22 is in state five. At this time, the second antenna 22 constitutes the IFA antenna, as shown in the reference. Figure 11 The diagram shows a simplified antenna pattern when the second antenna 22 is in state five, at which time the first antenna 12 is in half-wave mode.

[0057] It should be noted that, in this embodiment of the invention, the first antenna 12 and the second antenna 22 in the folded electronic device 100 can be prevented from interfering with each other under different circumstances. For example, when neither the first antenna 12 nor the second antenna 22 is working, the folded electronic device 100 can control the first antenna 12 to be in a first working state and the second antenna 22 to be in a second working state. At this time, the phase control module 229 can control the phase difference between the two feed signals entering the second radiation structure 221 to be 180°. At this time, current flows through the second antenna 22, and the current flow direction in the second antenna 22 is the same as the current flow direction in the first antenna 12. Alternatively, the electronic device 100 can be folded while the first antenna 12 and the second antenna 22 are working. Specifically, the first antenna 12 can be in any of the states one, two, and three, and the second antenna 22 can be in state five. In this case, the electronic device 100 can control the first antenna 12 to be in the first working state, while the phase control module 229 can control the phase difference of the two feed signals entering the second radiation structure 221 to be 180°, so that the current direction in the second antenna 22 changes, and the second antenna 22 is in the second working state, i.e., state four, so that the current flow direction in the second antenna 22 is opposite to the current flow direction in the first antenna 12.

[0058] The first switch and the second switch 228 can be electrically connected to the control module of the electronic device 100, such as the CPU in the electronic device 100. The user can send a mode switching command to the electronic device 100, and the control module of the electronic device 100 controls the state of the first switch and the second switch 228 according to the mode switching command, thereby controlling the working state of the first antenna 12 and the second antenna 22. To facilitate user operation of the electronic device 100, the electronic device 100 can also detect whether it is in a folded state. When the electronic device 100 is in a folded state, the control module automatically controls the first antenna 12 to be in a first working state and the second antenna 22 to be in a second working state.

[0059] Additionally, in some embodiments, such as Figure 5 , Figure 6 As shown, the first switch can be set close to the first excitation source 126, and the second switch 228 can be set close to the second excitation source 226.

[0060] The first switch is positioned close to the first excitation source 126, and the second switch 228 is positioned close to the second excitation source 226, thereby reducing the impact of stub loading on impedance.

[0061] It should be noted that the positions of the first switch and the second switch 228 can be matched to the performance of the electronic device 100 to reduce the impact of stub loads on impedance. For example, the distance between the first switch and the first excitation source 126 can be 4mm, 5mm, 6mm, etc., and the distance between the second switch 228 and the second excitation source 226 can also be 4mm, 5mm, 6mm, etc. The specific positions of the first switch and the second switch 228 are not specifically limited in this embodiment of the invention.

[0062] It should also be noted that, in the embodiments of the present invention, the electronic device 100 includes, but is not limited to, mobile phones, tablet computers, laptops, handheld computers, vehicle terminals, wearable devices, and pedometers.

[0063] Furthermore, in this embodiment of the invention, the first antenna 12 and the second antenna 22 are not limited to being used in the same frequency state. That is, when the electronic device 100 is in a folded state, the first antenna 12 and the second antenna 22 can operate in the same frequency band, or they can operate in different frequency bands. When the first antenna 12 and the second antenna 22 operate in the same frequency band, the first antenna 12 is in a first operating state and the second antenna 22 is in a second operating state, which avoids mutual interference between the first antenna 12 and the second antenna 22. When the first antenna 12 and the second antenna 22 operate in different frequency bands, the first antenna 12 can be in the first operating state and the second antenna 22 can be in the second operating state; in addition, the first antenna 12 and the second antenna 22 can also be in other states.

[0064] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0065] Although alternative embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make further changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the alternative embodiments and all changes and modifications falling within the scope of the embodiments of the present invention.

[0066] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used merely to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or terminal device that includes that element.

Specific examples have been used to illustrate the principle and implementation of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the principle and implementation of the present invention.
