It will be appreciated that the foldable electronic device 1 may be a foldable display device or a foldable non-display device. In the present application, the electronic device 1 is taken as an example of a foldable mobile phone, and other devices may refer to the detailed description in the present application. It is understood that, in other embodiments, the electronic device 1 may also be an unfolded electronic device. In the schematic diagram of the embodiment of the present application, the antenna module 10 and the like shown in fig. 3 are a back view, that is, the antenna module 10 is seen from the housing 40 of the electronic device 1 toward the display screen 30 of the electronic device 1.
Referring to fig. 2, the electronic device 1 includes a foldable main body 20 and an antenna module 10. The foldable body 20 has an unfolded state and a folded state. The foldable body 20 is a skeleton structure of the electronic apparatus 1. The main body form of the foldable main body 20 coincides with the main body form of the electronic apparatus 1. When the foldable body 20 is in the unfolded state, the electronic apparatus 1 is in the unfolded state; when the foldable body 20 is in the folded state, the electronic apparatus 1 is in the folded state. Specifically, the foldable body 20 includes, but is not limited to, a middle frame of the electronic device 1. In the present embodiment, the foldable body 20 is taken as an example of a middle frame of the electronic device 1.
In the unfolded state, the foldable main body 20 may be in a flat state of 180 °, or in a flat state of approximately 180 ° (e.g., 170 °, or 175 °, or 185 °), or in a bent state with a certain bending angle, and the bending angle is not limited. In the present embodiment, a flattened state in which the developed state is 180 ° is taken as an example. When the electronic apparatus 1 has the display screen 30, the expanded area of the display screen 30 in the expanded state is relatively large, so that the user can enjoy the electronic apparatus 1 of a large screen. The folded state is a state in which the foldable main body 20 is folded and stacked, and at this time, the electronic apparatus 1 is small in overall size and convenient to carry.
Alternatively, the foldable body 20 includes, but is not limited to, a double-folded structure having one rotation axis, and may also be a triple-folded structure, a quadruple-folded structure, or the like having two or more rotation axes. The present embodiment will be described by taking the foldable main body 20 as a half-folded structure as an example.
Referring to fig. 2, the foldable main body 20 includes a first main body 210 and a second main body 220 rotatably connected to each other, and in the present embodiment, at least one of the first main body 210 and the second main body 220 is rotatably connected to each other by a rotating shaft 230. In other words, the foldable body 20 includes a first body 210, a hinge 230, and a second body 220 connected in sequence. In other embodiments, the first body 210 is directly connected to the second body 220, and the connection between the first body 210 and the second body 220 is bendable. The embodiment of the present application does not limit the manner in which the foldable main body 20 is bent, as long as the foldable main body 20 can be bent.
It should be noted that at least a portion of the first body 210 of the foldable body 20 is made of a conductive material, at least a portion of the second body 220 of the foldable body 20 is made of a conductive material, and the first body 210 is electrically connected to the second body 220. When the foldable main body 20 further includes a rotating shaft 230, at least a portion of the rotating shaft 230 is made of a conductive material, and the first main body 210 is electrically connected to the second main body 220 through the rotating shaft 230. As can be seen, the foldable body 20 can serve as a reference ground (also referred to as a ground pole) of the antenna module 10.
For convenience of description, it is defined that the connection direction of the first body 210, the rotation shaft 230, and the second body 220 is the negative X-axis direction, and the rotation axis L0 direction of the foldable body 20 is the Y-axis direction, that is, in the present embodiment, the extension direction of the rotation shaft 230 is the Y-axis direction. The thickness direction of the foldable body 20 in the unfolded state is the Z-axis direction. Wherein, the X-axis direction, the Y-axis direction and the Z-axis direction are vertical to each other. Wherein the direction indicated by the arrow is the forward direction.
Optionally, referring to fig. 2, the electronic device 1 further includes a display screen 30. The display 30 is disposed on one side of the foldable main body 20, in this embodiment, the display 30 is disposed on the front side of the foldable main body 20 (the front side refers to a direction toward a user when the user normally uses the display 30), and optionally, in one embodiment, a portion of the display 30 corresponding to the rotation shaft 230 is a flexible display 30. Alternatively, in another embodiment, the display 30 is not disposed at a position corresponding to the rotation shaft 230, and two display screens 30 are disposed at the front sides of the first body 210 and the second body 220, respectively.
In the present embodiment, the display panel 30 includes a first display portion 310, a second display portion 320, and a connecting portion 330. The first display portion 310 is disposed corresponding to the first main body 210, the second display screen 320 is disposed corresponding to the second main body 220, the connecting portion 330 is disposed corresponding to the rotation shaft 230, and the connecting portion 330 is bendable. In the present embodiment, the display 30 is an integral structure. In another embodiment, the first display portion 310 and the second display portion 320 are separate bodies.
Optionally, referring to fig. 2, the electronic device 1 further includes a housing 40. The housing 40 includes a bezel 410 and a rear cover 420. When the electronic device 1 is in the flat state or the approximately flat state, the display screen 30 and the rear cover 420 are respectively located on two opposite sides (front and rear sides) of the foldable main body 20, wherein the frame 410 is connected between the display screen 30 and the rear cover 420 and surrounds the foldable main body 20, and the display screen 30, the frame 410 and the rear cover 420 enable the electronic device 1 to form a relatively closed complete machine. Of course, in other embodiments, the rear side of the electronic device 1 may also be provided with the display screen 30.
The frame 410 and the rear cover 420 may be an integral structure or a separate structure. When the bezel 410 and the rear cover 420 are separate structures, the inside of the bezel 410 may be integrated with the middle frame (the foldable main body 20). A plurality of mounting grooves for mounting various electronic devices are formed on the middle frame. The display screen 30, the middle frame and the rear cover 420 form accommodating spaces on two sides of the middle frame after being covered. The electronic device 1 further includes a circuit board (including a main board, a sub board, a flexible circuit board, etc.) disposed in the accommodating space, a battery, a camera module, a microphone, a receiver, a speaker, a face recognition module, a fingerprint recognition module, etc., which are capable of implementing the basic functions of the electronic device 1, and are not described in detail in this embodiment. It should be understood that the above description of the electronic device 1 is only an illustration of an environment in which the antenna module 10 is applied, and the specific structure of the electronic device 1 should not be construed as limiting the antenna module 10 provided in the present application.
The antenna module 10 may be disposed inside the housing 40 of the electronic device 1, or partially integrated with the housing 40, or partially disposed outside the housing 40. The antenna module 10 is configured to receive and transmit a radio frequency signal, where the radio frequency signal is transmitted in an air medium as an electromagnetic wave signal, so as to implement a communication function of the electronic device 1. The position of the antenna module 10 on the electronic device 1 is not specifically limited in the present application, and the position of the antenna module 10 on the electronic device 1 shown in fig. 2 is only an example.
It should be understood that, although the antenna module 10 illustrated in fig. 2 and 3 of the present embodiment includes the third radiator 150 and the fourth radiator 160 in addition to the first radiator 130 and the second radiator 140, it should be noted that in other embodiments, the antenna module 10 may not include the third radiator 150 and does not include the fourth radiator 160. Referring to fig. 4, fig. 4 is a top view of a part of the antenna module according to another embodiment of fig. 1 in an unfolded state.
The electronic device 1 includes an attitude recognition sensor 50, an antenna module 10, and a processor 60. The gesture recognition sensor 50 is used to recognize the current gesture of the electronic apparatus 1. The antenna module 10 includes a first feed 110, a switch 120, a first radiator 130, and a second radiator 140. The first feed 110 is used to generate an excitation current, so that the first radiator 130 or the second radiator 140 supports a frequency band for positioning. The switch 120 is electrically connected to the first feed source 110, the first radiator 130 and the second radiator 140 are disposed at an interval, and a main radiation direction of the first radiator 130 is different from a main radiation direction of the second radiator 140. The processor 60 is electrically connected to the gesture recognition sensor 50 and the switch 120, respectively, and is configured to control the switch 120 to be electrically connected to one of the first radiator 130 and the second radiator 140 according to the current gesture of the electronic device 1, where the strength of the signal received by the one of the first radiator 130 and the second radiator 140 is greater than the strength of the signal received by the other of the first radiator 130 and the second radiator 140.
It can be understood that, in the embodiment of the present application, there is no limitation on the signal strength of the switch 120 electrically connected to the one receiving the frequency band and the signal strength of the other receiving the frequency band. In one embodiment, when the processor 60 is electrically connected to the gesture recognition sensor 50 and the switch 120 respectively, and is configured to control the switch 120 to be electrically connected to one of the first radiator 130 and the second radiator 140 according to the current gesture of the electronic device 1, the signal strength of the one receiving the frequency band is greater than the signal strength of the other receiving the frequency band. In other embodiments, the processor 60 is electrically connected to the gesture recognition sensor 50 and the switch 120, respectively, and configured to control one of the first radiator 130 and the second radiator 140 to receive the signal of the frequency band when the switch 120 is electrically connected to the other of the first radiator 130 and the second radiator 140 according to the current gesture of the electronic device 1, where the signal strength of the frequency band received by the one of the first radiator and the second radiator may also be less than or equal to the signal strength of the frequency band received by the other of the first radiator and the second radiator.
In this embodiment, it is described as an example that when the first feed 110 is connected to the one of the first radiator 130 and the second radiator 140, the signal strength of the frequency band received and transmitted by the one is greater than the signal strength of the frequency band received and transmitted by the first feed 110 through the other of the first radiator 130 and the second radiator 140. It is to be understood that no limitation with respect to the embodiments of the disclosure is intended.
Specifically, in an embodiment, the processor 60 controls the switch 120 to be electrically connected to the first radiator 130 according to the current posture of the electronic device 1, wherein the signal strength of the frequency band received by the first feed 110 through the first radiator 130 is greater than the signal strength of the frequency band received by the first feed 110 through the second radiator 140. In another embodiment, the processor 60 controls the switch 120 to be electrically connected to the second radiator 140 according to the current posture of the electronic device 1, wherein the signal strength of the frequency band received by the first feed 110 through the second radiator 140 is greater than the signal strength of the frequency band received by the first feed 110 through the first radiator 130.
When the first feed source 110 is connected to the one of the first radiator 130 and the second radiator 140, the main radiation direction of the one is upward compared with the main radiation direction of the other one of the first radiator 130 and the second radiator 140. Generally, the antenna module 10 communicates with a satellite, which is usually located above the earth, by using radio frequency signals for positioning. When the main radiation direction of the one is upward compared with the main radiation direction of the other, the strength of the first feed 110 receiving the signal of the frequency band through the one is greater than the strength of the first feed 110 receiving the signal of the frequency band through the other. It should be noted that, the upward direction is referred to as vertical upward. The main radiation direction of one is upward compared with the main radiation direction of the other, which means that the main radiation direction of one is closer to a vertical ground surface than the main radiation direction of the other and points to an upward vertical line.
It should be noted that when the first feed 110 is connected to the one of the first radiator 130 and the second radiator 140, the main radiation direction of the one is upward compared to the main radiation direction of the other one, which is an embodiment that the strength of the first feed 110 receiving the signal of the frequency band through the second radiator 140 is greater than the strength of the first feed 110 receiving the signal of the frequency band through the first radiator 130. When the electronic device 1 horizontally faces upward with the display screen 30, or when the display screen 30 horizontally faces downward, and the main radiation direction of the first radiator 130 and the main radiation direction of the second radiator 140 are more difficult to determine which radiator's main radiation direction faces upward than the vertical line, as long as it is satisfied that the processor 60 controls the switch 120 to be electrically connected to one of the first radiator 130 and the second radiator 140 according to the current posture of the electronic device 1, wherein when the first feed 110 is connected to the one of the first radiator 130 and the second radiator 140, the strength of receiving the signal of the frequency band by the one is greater than the strength of receiving the signal of the frequency band by the other of the first radiator 130 and the second radiator 140 by the first feed 110.
The gesture recognition sensor 50 may be, but is not limited to, the gyroscope, the accelerometer, the electronic compass, and the like. The attitude sensor may identify the current attitude of the electronic device 1.
The first feed 110 is used to generate an excitation current, so that the first radiator 130 or the second radiator 140 supports a frequency band for positioning. The frequency band used for positioning is generally referred to as a Global Navigation Satellite System (GNSS) signal frequency band. Examples include, but are not limited to, global Positioning System (GPS) Positioning, beidou Positioning, GLONASS Positioning, GALILEO Positioning, etc. The frequency band generated by the first feed 110 for positioning is taken as a GPS frequency band as an example, and it should be understood that the frequency band is not limited to the electronic device 1 provided in the embodiments of the present application. The GPS frequency band includes, but is not limited to, a GPS L1 frequency band, or a GPS L5 frequency band.
The switch 120 may be disposed on a circuit board (e.g., a PCB), and the switch 120 may be disposed on the circuit board by, but not limited to, soldering, or bonding with conductive glue. When the switch 120 is disposed on the circuit board, the switch 120 can be electrically connected to the processor 60 through a trace on the circuit board, or a coaxial line. The switch 120 can also be electrically connected to the first radiator 130 and the second radiator 140 by a trace on the circuit board or a coaxial line. The present embodiment does not limit the type of the switch 120, as long as the switch 120 can be electrically connected to one of the first radiator 130 and the second radiator 140 under the control of the processor 60.
The shape of the first radiator 130 includes, but is not limited to, a strip, a sheet, a rod, a coating, a film, etc. The first radiator 130 shown in the schematic diagram of the present embodiment is merely an example, and the shape of the first radiator 130 provided in the present application is not limited. Optionally, when the frame 410 in the housing 40 of the electronic device 1 is made of a conductive material, the first radiator 130 may be integrated with the frame 410, that is, the first radiator 130 is a frame antenna, and a part of the frame is used as the first radiator 130. Still alternatively, the first radiator 130 may also be a portion of the middle frame (i.e., the foldable main body 20), and thus, the first radiator 130 and the middle frame are interconnected into a single structure. The first radiator 130 may be formed by cutting a slit in the middle frame. In this embodiment, the frame 410 of the housing 40 corresponding to the first radiator 130 may be made of a non-conductive material, so that the first radiator 130 can receive and transmit electromagnetic wave signals through the frame. Still optionally, the antenna formed by the first radiator 130 is a bracket antenna.

The electromagnetic wave signal of the first preset frequency band is different from the GPS frequency band. In other words, when the electronic apparatus 1 is in the flattened state and the navigation function of the electronic apparatus 1 is not turned on, or when the electronic apparatus 1 is in the folded state: the second radiator 140 is used as another antenna radiator, such as a 4G antenna, or a 5G antenna.

When the preset content is displayed on the display 30, indicating that the display 30 is used, the processor 60 will play the voice in the navigation application installed in the electronic device 1 through the speaker 80, and the navigation function can still be used in the case that the preset content is displayed on the display 30. Therefore, the electronic device 1 can watch the preset content through the display screen 30 and can also use the navigation function.
Referring to fig. 23, fig. 23 is a circuit block diagram of an electronic device according to still another embodiment of the present application. The electronic device 1 further comprises a display 30 and a communication unit 90.

The communication unit 90 may include the other of the first radiator 130 and the second radiator 140. The other one is not electrically connected to the first feed source 110, and the communication unit 90 including the other one can avoid adding an additional radiator, so that the electronic device 1 is thinner and lighter. It is understood that in other embodiments, the communication unit 90 includes other radiators as long as the communication function can be achieved.
It can be understood that, when the antenna module 10 includes the first radiator 130 and the second radiator 140, and further includes the third radiator 150 and the fourth radiator 160, the processor 60 controls the switch 120 to be electrically connected to one of the first radiator 130 and the second radiator 140 according to the current posture of the electronic device 1, so that the first feed 110 is electrically connected to one of the first radiator 130 and the second radiator 140 through the switch 120, and receives and transmits the electromagnetic wave signal of the GPS frequency band through the one. The communication unit 90 may include the other of the first radiator 130 and the second radiator 140, or the third radiator 150 or the fourth radiator 160. The other one, the third radiator 150 and the fourth radiator 160 are not electrically connected to the first feed source 110, and the communication unit 90 includes any one of the other one, the third radiator 150 and the fourth radiator 160, which can avoid adding an additional radiator, so that the electronic device 1 is thinner and lighter.

The processor 60 outputs a display interface of a navigation application in the electronic device 1 through the communication unit 90 to be displayed on a vehicle-mounted screen communicatively connected to the communication unit 90.
When the preset content is displayed on the display screen 30, indicating that the display screen 30 is used, the processor 60 outputs a display interface of a navigation application in the electronic device 1 through the communication unit 90 to be displayed on a vehicle-mounted screen communicatively connected to the communication unit 90, and navigation is still possible in a case where the preset content is displayed on the display screen 30. Therefore, the dual effects of the electronic device 1 being capable of using the navigation function as well as watching the preset content through the display screen 30 are achieved.
With reference to fig. 1 and fig. 3, the electronic apparatus 1 has a first folding axis L1. When the electronic device 1 is in the flat state, the first radiator 130 and the third radiator 150 are located on the same side of the first folding axis L1, the second radiator 140 and the fourth radiator 160 are located on the same side of the first folding axis L1, and the second radiator 140 and the first radiator 130 are located on different sides of the first folding axis L1. The folded state includes a first folded state, and when the electronic device 1 is in the first folded state, the first radiator 130 and the fourth radiator 160 are arranged in a staggered manner, and the second radiator 140 and the third radiator 150 are arranged in a staggered manner. When the electronic apparatus 1 is in the first folded state, the electronic apparatus 1 is folded along the first folding axis L1 from the flat state.
In this embodiment, the folded state includes a first folded state, when the electronic device 1 is in the first folded state, the first radiator 130 and the fourth radiator 160 are arranged in a staggered manner, and there is no overlap between the first radiator 130 and the fourth radiator 160; the second radiator 140 and the third radiator 150 are disposed in a staggered manner, and there is no overlap between the second radiator 140 and the third radiator 150. Therefore, the antenna module 10 can still have better communication performance when the electronic device 1 is in the first folded state.
When the electronic device 1 is in the first folded state, the first radiator 130 and the fourth radiator 160 are disposed in a staggered manner, so that shielding and interference between the first radiator 130 and the fourth radiator 160 can be reduced or even avoided. For example, when the processor 60 controls the switch 120 to be electrically connected to the first radiator 130, the first feed 110 receives and transmits electromagnetic wave signals in a GPS frequency band through the first radiator 130, and when the electronic device 1 is in the first folded state, the shielding and interference of the fourth radiator 160 on the electromagnetic wave signals in the GPS frequency band received and transmitted by the first radiator 130 can be reduced or even avoided. Accordingly, for example, when the processor 60 controls the switch 120 to be electrically connected to the fourth radiator 160, the first feed 110 transceives electromagnetic wave signals in a GPS frequency band through the fourth radiator 160, and when the electronic device 1 is in the first folding state, the shielding and interference of the first radiator 130 on the electromagnetic wave signals transceived by the fourth radiator 160 in the GPS frequency band can be reduced or even avoided.
When the electronic device 1 is in the first folded state, the second radiator 140 and the third radiator 150 are arranged in a staggered manner, so that shielding and interference between the second radiator 140 and the third radiator 150 can be reduced or even avoided.
For example, when the processor 60 controls the switch 120 to be electrically connected to the second radiator 140, the first feed 110 receives and transmits the electromagnetic wave signal in the GPS frequency band through the second radiator 140, and when the electronic device 1 is in the first folded state, the shielding and interference of the electromagnetic wave signal in the GPS frequency band received and transmitted by the second radiator 140 by the third radiator 150 can be reduced or even avoided.

In the present embodiment, the electronic apparatus 1 has a second folding axis L2. When the electronic device 1 is in the flat state, the first radiator 130 and the fourth radiator 160 are located on the same side of the second folding axis L2, the second radiator 140 and the third radiator 150 are located on the same side of the second folding axis L2, and the second radiator 140 and the first radiator 130 are located on different sides of the second folding axis L2.

Therefore, the antenna module 10 can still have better communication performance when the electronic device 1 is in the second folded state.
When the electronic device 1 is in the second folded state, the first radiator 130 and the third radiator 150 are disposed in a staggered manner, so that shielding and interference between the first radiator 130 and the third radiator 150 can be reduced or even avoided. For example, when the processor 60 controls the switch 120 to be electrically connected to the first radiator 130, the first feed 110 receives and transmits electromagnetic wave signals in a GPS frequency band through the first radiator 130, and when the electronic device 1 is in the second folded state, the blocking and interference of the electromagnetic wave signals in the GPS frequency band received and transmitted by the first radiator 130 by the third radiator 150 can be reduced or even avoided. Accordingly, for example, when the processor 60 controls the switch 120 to be electrically connected to the third radiator 150, the first feed 110 receives and transmits electromagnetic wave signals in the GPS frequency band through the third radiator 150, and when the electronic device 1 is in the second folded state, the shielding and interference of the first radiator 130 to the electromagnetic wave signals in the GPS frequency band received and transmitted by the third radiator 150 can be reduced or even avoided.
When the electronic device 1 is in the second folded state, the second radiator 140 and the fourth radiator 160 are disposed in a staggered manner, so that shielding and interference between the second radiator 140 and the fourth radiator 160 can be reduced or even avoided.

In the electronic device 1 according to the embodiment of the present invention, the current posture of the electronic device 1 recognized by the posture recognition sensor 50 is linked with the switching of the switch 120, so as to achieve the purpose of intelligently switching the antenna radiator. The processor 60 intelligently controls the switch 120 to be electrically connected to the antenna radiator with a better upper hemisphere in the far-field pattern according to the current posture of the electronic device 1, so that the antenna module 10 of the electronic device 1 has better communication performance when communicating by using the GPS frequency band.
In an embodiment, when the electronic device 1 is in a flat state (also referred to as a large screen state), the first radiator 130, the second radiator 140, the third radiator 150, and the fourth radiator 160 of the antenna module 10 in the electronic device 1 are further based on the recognition function of the attitude recognition sensor 50, and specifically, the attitude sensor recognizes the current attitude of the electronic device 1 as a first attitude (in this embodiment, a left landscape attitude), a second attitude (in this embodiment, a right landscape attitude), a third attitude (in this embodiment, an inverted attitude), or a fourth attitude (in this embodiment, an upright attitude), and the processor 60 controls the switch 120 to be electrically connected to an antenna radiator with an optimal upper hemisphere in a far-field pattern, so as to obtain an optimal navigation performance.
For example, when the gesture recognition sensor 50 recognizes that the current gesture of the electronic device 1 is the second gesture (in the present embodiment, the right landscape) the processor 60 generates a switch switching control signal (or referred to as a switch switching state signal) and controls the switch 120 to be electrically connected to the second radiator 140, that is, the second radiator 140 operates, so that the X-axis forward direction (the direction toward the sky) has a good upper hemisphere ratio.
It should be noted that, in other embodiments, when the electronic device 1 is in the folded state, based on the recognition function of the gesture recognition sensor 50, the processor 60 controls the switch 120 to be electrically connected to the antenna radiator with the upper hemisphere of the far-field pattern being optimal, so as to obtain the optimal navigation performance.
When the antenna module 10 includes the first radiator 130, the second radiator 140, the third radiator 150, and the fourth radiator 160, the layout of the four radiators, i.e., the first radiator 130, the second radiator 140, the third radiator 150, and the fourth radiator 160, is designed based on the principle that the far-field pattern is along the direction of current lag, so that the switch 120 can be switched to the antenna radiator with the upper hemisphere occupying a better ratio in the far-field pattern in each posture of the electronic device 1, thereby achieving a better upper hemisphere occupying ratio in each direction.
It should be noted that, in the present application, the layout of the four radiators, i.e., the first radiator 140, the second radiator 150, and the fourth radiator 160, is adopted to ensure that the switch 120 can switch the antenna radiator with the upper hemisphere in the far-field pattern better in each posture of the electronic device 1, so as to achieve the upper hemisphere in each direction better. If the requirement is not particularly high for some navigational patterns (e.g., the upper hemisphere of the far-field pattern is around 50%), the antenna module 10 may include two radiators, such as the first radiator 130 and the second radiator 140, instead of the third radiator 150 and the fourth radiator 160. In other embodiments, the antenna module 10 may include the third radiator 150 and the fourth radiator 160, but not the first radiator 130 and the second radiator 140. It should be noted that, when the antenna module 10 includes the third radiator 150 and the fourth radiator 160, but does not include the first radiator 130 and the second radiator 140, the third radiator 150 may also be named as the first radiator 130, and the fourth radiator 160 may also be named as the second radiator 140.
While the foregoing is directed to embodiments of the present application, it will be appreciated by those skilled in the art that various modifications may be made without departing from the scope of the present application, and that such modifications and adaptations are intended to be within the scope of the present application.
