Description

Technical Field

[0001] The present application relates to the field of antenna technology, and in particular to a foldable electronic device and a method for processing antenna signals. Background Art

[0002] The antenna design of conventional candy-bar phones is generally a single-antenna solution. In order to obtain better performance, the antenna is usually placed at the top of the phone to ensure that the antenna's maximum radiation direction is toward the sky for better signal reception. However, when the phone is folded, the antenna that was originally at the top of the phone is folded to the bottom. At this time, the foldable electronic device is easily blocked, resulting in a radiation effect that is usually worse than the unfolded state, and the antenna's maximum radiation direction is toward the ground, which ultimately leads to a significant reduction in linear radiation efficiency and reduces the signal quality of the foldable electronic device.

[0003] That is, the signal quality of the foldable electronic device in the prior art is poor when it is in the folded state. Summary of the invention

[0004] The embodiments of the present application provide a foldable electronic device and a method for processing antenna signals, which can improve the signal quality of the foldable electronic device when it is in a folded state.

[0005] In a first aspect, the foldable electronic device provided by the present application includes:

[0006] a first shell;

[0007] A second shell, wherein the second shell and the first shell are rotatably connected via a rotating shaft mechanism;

[0008] a first antenna, wherein the first antenna is disposed on the first housing;

[0009] a second antenna, the second antenna being disposed on the rotating shaft mechanism;

[0010] Wherein, at least one of the first antenna and the second antenna is used to transmit wireless signals;

[0011] When the first shell and the second shell are in a folded state, the maximum radiation direction of the second antenna is the direction in which the hinge mechanism is away from the second shell.

[0012] In a second aspect, the antenna signal processing method provided by the present application includes:

[0013] Detecting whether a foldable electronic device is in a folded state;

[0014] If the foldable electronic device is in a folded state, obtaining a first antenna signal of the first antenna and a second antenna signal of the second antenna;

[0015] The first antenna signal and the second antenna signal are processed to obtain an output signal.

[0016] In the present application, compared with the related art, when the user holds the second shell of the foldable electronic device, the second shell is in a vertical placement state. If the foldable electronic device is folded into a folded state, the first shell is also flipped to a vertical placement state, and the hinge mechanism is located above the first shell and the second shell. At this time, the maximum radiation direction of the second antenna is the direction in which the hinge mechanism is away from the second shell. The second antenna can radiate with maximum radiation power in the upward direction, and the first shell will not block the second antenna after being flipped. The antenna radiation power of the foldable electronic device in the folded state can be increased, and the signal quality of the foldable electronic device in the folded state can be improved.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0034] See also Figures 1 to 3 , Figure 1 is a schematic structural diagram of a first embodiment of a foldable electronic device provided in an embodiment of the present application when in an unfolded state; Figure 2 is a structural schematic diagram of a first embodiment of a foldable electronic device provided in an embodiment of the present application when in a folded state; Figure 3 It is a side schematic diagram of the first embodiment of the foldable electronic device provided in the embodiments of the present application in a folded state.

[0035] In the embodiment of the present application, the foldable electronic device 10 can be any device equipped with a processor and having processing capabilities, such as a fixed foldable electronic device with a processor, such as a smart phone, a tablet computer, a PDA, a laptop computer, etc. In the implementation of the present application, the foldable electronic device 10 is described as a mobile phone.

[0036] In the embodiment of the present application, the foldable electronic device 10 includes a first housing 11 , a second housing 12 , a hinge mechanism 13 , a first antenna 141 and a second antenna 142 .

[0037] The first shell 11 and the second shell 12 are two rotatable components of the foldable electronic device 10. The first shell 11 and the second shell 12 are connected by a hinge mechanism 13, wherein the first shell 11 and the second shell 12 can both rotate relative to the hinge mechanism 13, or only the first shell 11 can rotate around the hinge mechanism 13, or only the second shell 12 can rotate around the hinge mechanism 13. When the first shell 11 and the second shell 12 are in a folded state, the first shell 11 and the second shell 12 are arranged opposite to each other, and the first shell 11 and the second shell 12 are located on the same side of the hinge mechanism 13. When the first shell 11 and the second shell 12 are in an unfolded state, the first shell 11 and the second shell 12 are located on both sides of the hinge mechanism 13 respectively.

[0038] In the embodiment of the present application, the first antenna 141 and the second antenna 142 are both used for transmitting and receiving antenna signals, the first antenna 141 is disposed in the first housing 11, and the second antenna 142 is disposed in the second housing 12. When the foldable electronic device 10 is in the unfolded state, the first housing 11 and the second housing 12 are respectively located on both sides of the hinge mechanism 13, and the maximum radiation direction of the first antenna 141 is the direction in which the first housing 11 is away from the hinge mechanism 13. When the foldable electronic device 10 is in the folded state, the first housing 11 and the second housing 12 are located on the same side of the hinge mechanism 13, and the maximum radiation direction of the second antenna 142 is the direction in which the hinge mechanism 13 is away from the second housing 12.

[0039] The first antenna 141 and the second antenna 142 may be positioning antennas, Bluetooth antennas, or WiFi antennas. For example, the first antenna 141 and the second antenna 142 are both positioning antennas for sending and receiving satellite positioning signals. The positioning antenna may be a Global Positioning System (GPS) antenna, a Beidou antenna, etc., which may be set according to the specific requirements.

[0040] The maximum radiation direction is the direction in which the antenna radiates the most, and the radiation power of the antenna is the highest in the maximum radiation direction. The antenna radiation pattern refers to a graph showing how the relative field strength of the radiation field changes with direction at a certain distance from the antenna. It is a graphical description of the antenna radiation characteristics, and various antenna parameters can be observed from the antenna pattern. It is usually represented by two mutually perpendicular plane patterns in the direction of the antenna's maximum radiation. Antenna Direction Figure 1 Generally, they are in the shape of petals, which are called lobes or beams. The lobe with the maximum radiation direction is called the main lobe, and the others are called side lobes or side lobes, which are divided into the first side lobe, the second side lobe, etc. The beam in the opposite direction to the main lobe is called the back lobe.

[0041] When the user holds the second housing 12 of the foldable electronic device 10 , the second housing 12 is in a vertical placement state.

[0042] like Figure 2 and Figure 3 As shown, if the foldable electronic device 10 is folded into a folded state, that is, the first shell 11 and the second shell 12 are located on the same side of the hinge mechanism 13, the first shell 11 is also flipped to a vertical placement state, and the hinge mechanism 13 is located above the first shell 11 and the second shell 12. At this time, the maximum radiation direction of the second antenna 142 is the direction in which the hinge mechanism 13 is away from the second shell 12. The second antenna 142 can radiate with maximum radiation power in the upward direction, and the first shell 11 will not block the second antenna 142, which can increase the antenna radiation power of the foldable electronic device 10 in the folded state and improve the signal quality of the foldable electronic device.

[0043] Furthermore, the display screen 19 includes a first screen body 191 and a second screen body 192, wherein the first screen body 191 is mounted on the first shell 11, and the second screen body 192 is mounted on the second shell 12. The display screen 19 may be a flexible display screen, wherein the first screen body 191 and the second screen body 192 are integrally designed, and the display screen 19 may be flatly spread out on the first shell 11 and the second shell 12. The display screen 19 may fully display the content, i.e., the display screen 19 is a whole display screen 19, and the first screen body 191 and the second screen body 192 are different display areas of the display screen 19. The first screen body 191 and the second screen body 192 may also be separated from each other, and when the display surfaces of the first screen body 191 and the second screen body 192 are located in the same plane, the first screen body 191 and the second screen body 192 are combined together to display the complete content. The display screen 19 may be an organic light-emitting diode display screen (OLED) or other display screens 19, which are not limited here.

[0044] Furthermore, in order to improve the signal quality when the foldable electronic device 10 is in the unfolded state, as Figure 1 As shown, when the first shell 11 and the second shell 12 are in the unfolded state, the first shell 11 and the second shell 12 are respectively located on both sides of the hinge mechanism 13, the display surface of the first screen 191 and the display surface of the second screen 192 are located in the same plane, and the maximum radiation direction of the first antenna 141 is the direction in which the first shell 11 is away from the hinge mechanism 13. The first antenna 141 in the first shell 11 is located above the hinge mechanism 13, and the first antenna 141 can radiate with maximum radiation power in the upward direction, which can improve the antenna radiation power of the foldable electronic device 10 in the unfolded state and improve the signal quality of the foldable electronic device. Of course, in other embodiments, when the foldable electronic device 10 is in the unfolded state, the maximum radiation direction of the first antenna 141 can also be other directions, and this application does not limit this.

[0045] Further, the first shell 11 includes a bottom boundary 112 close to the hinge mechanism 13 and a top boundary 111 away from the hinge mechanism 13, and the distance between the first antenna 141 and the bottom boundary 112 is greater than the distance between the first antenna 141 and the top boundary 111. Optionally, the first antenna 141 contacts the top boundary 111 or extends out of the top boundary 111. The first antenna 141 is close to the top boundary 111, and the first antenna 141 is located at the top of the first shell 11, which is not easily blocked, and the first antenna 141 is far away from the second antenna 142 to avoid mutual interference, which can improve the radiation power and the signal quality of the foldable electronic device 10.

[0046] See also Figures 4 to 5 , Figure 4is a structural schematic diagram of a second embodiment of a foldable electronic device provided in an embodiment of the present application when in an unfolded state; Figure 5 It is a structural diagram of the first signal processing module in the second embodiment of the foldable electronic device provided in the embodiment of the present application.

[0047] In the embodiment of the present application, the foldable electronic device 10 includes a first housing 11, a second housing 12, a hinge mechanism 13, a display screen 19, a first antenna 141, and a second antenna 142. The first housing 11 and the second housing 12 are two rotatable components of the foldable electronic device 10. The first housing 11 and the second housing 12 are connected by a hinge mechanism 13. The first antenna 141 and the second antenna 142 are both used for transmitting and receiving antenna signals, the first antenna 141 is arranged in the first housing 11, and the second antenna 142 is arranged in the second housing 12. When the foldable electronic device 10 is in an unfolded state, the display surface of the first screen body 191 and the display surface of the second screen body 192 are located in the same plane, and the maximum radiation direction of the first antenna 141 is the direction in which the first housing 11 is away from the hinge mechanism 13. When the foldable electronic device 10 is in a folded state, the display surface of the first screen body 191 and the display surface of the second screen body 192 are arranged opposite to each other, and the maximum radiation direction of the second antenna 142 is the direction in which the hinge mechanism 13 is away from the second housing 12.

[0048] In the embodiment of the present application, the foldable electronic device 10 includes a first signal enhancement component 151, a second signal enhancement component 152 and an antenna selection switch 181. The first signal enhancement component 151 is arranged between the antenna selection switch 181 and the first antenna 141, and the second signal enhancement component 152 is arranged between the antenna selection switch 181 and the second antenna 142. The first signal enhancement component 151 enhances the first antenna signal to obtain a first enhanced signal, and the second signal enhancement component 152 enhances the second antenna 142 signal to obtain a second enhanced signal. The first signal enhancement component 151 is used to process the first enhanced signal and the second enhanced signal into one signal to obtain an output signal. The antenna selection switch 181 is electrically connected to the first antenna 141 and the second antenna 142, and is used to select one of the first antenna 141 and the second antenna 142 to transmit a wireless signal.

[0049] The present application first enhances the first antenna signal of the first antenna 141 and the second antenna signal of the second antenna 142 , and then processes the enhanced two signals into one signal, which can improve the quality of the output signal and improve the signal quality of the foldable electronic device 10 .

[0050] Furthermore, the foldable electronic device 10 includes a communication chip 16, and the antenna selection switch 181 inputs the output signal into the communication chip 16 for further signal processing. The communication chip 16 is electrically connected to the first antenna 141 and the second antenna 142; the communication chip 16 is used to process the wireless signal transmitted by at least one of the first antenna 141 and the second antenna 142.

[0051] In a specific embodiment, the communication chip 16 is a GPS chip, and at least one of the first antenna 141 and the second antenna 142 is used to transmit GPS signals. The communication chip 16 can be an SDR735 chip or other chips, which are not limited here.

[0052] In the embodiment of the present application, the first signal enhancement component 151 is close to the first antenna 141. The first signal enhancement component 151 is used to process the first antenna signal of the first antenna 141. The first signal enhancement component 151 is close to the first antenna 141, which can reduce the transmission distance of the signal between the first signal enhancement component 151 and the first antenna 141, and improve the effect of the first signal enhancement component 151 on the first antenna signal processing of the first antenna 141, thereby improving the signal processing effect of the foldable electronic device 10 and improving the signal quality of the foldable electronic device 10.

[0053] In the embodiment of the present application, the second signal enhancement component 152 is close to the second antenna 142. The second signal enhancement component 152 is used to process the second antenna signal of the second antenna 142. The second signal enhancement component 152 is close to the second antenna 142, and the distance between the second signal enhancement component 152 and the second antenna 142 is reduced, which can reduce the transmission distance of the signal between the second signal enhancement component 152 and the second antenna 142, and can improve the effect of the second signal enhancement component 152 on the second antenna 142 signal processing, thereby improving the signal processing effect of the foldable electronic device 10 and improving the signal quality of the foldable electronic device 10.

[0054] In the embodiment of the present application, the antenna selection switch 181 is a radio frequency switch, and the antenna selection switch 181 is used to select the one with the highest signal performance index between the first antenna 141 and the second antenna 142 to transmit the wireless signal. Specifically, the first antenna 141 and the second antenna 142 are both global positioning system (GPS) antennas, and the first antenna signal and the second antenna signal are GPS signals. The signal performance index is the carrier-to-noise ratio. The antenna selection switch 181 obtains the carrier-to-noise ratio of the first antenna signal and the second antenna signal, and determines the signal with the highest carrier-to-noise ratio between the first antenna signal and the second antenna signal as the output signal.

[0055] In a specific embodiment, when the first shell 11 and the second shell 12 are in the unfolded state, the antenna selection switch 181 is used to select the first antenna 141 to transmit wireless signals; when the first shell 11 and the second shell 12 are in the folded state, the antenna selection switch 181 is used to select the second antenna 142 to transmit wireless signals.

[0056] The present application sets up two signal enhancement modules, and the two signal enhancement modules are respectively close to the corresponding antennas to perform signal processing, which can improve the signal processing effect and improve the signal quality of the foldable electronic device 10.

[0057] For further information, see Figure 5 , the first signal enhancement component 151 includes a first filter 155, a low noise amplifier 156 and a second filter 157 connected in series. The low noise amplifier is used to amplify the signal. Of course, in other embodiments, the first signal enhancement component 151 may also include only the low noise amplifier 156, the first signal enhancement component 151 may also include only the low noise amplifier 156 and the second filter 157, or the first signal enhancement component 151 may also include only the first filter 155 and the low noise amplifier 156. The first filter 155 and the second filter 157 can be a surface acoustic wave filter (Surface Acoustic Wave, SAW), a bulk acoustic wave filter (Bulk Acoustic Wave, BAW), a film bulk acoustic resonator filter (Film Bulk Acoustic Resonator, FBAR), etc., which can be selected according to the specific situation.

[0058] Among them, the surface acoustic wave filter is a transducer-type passive bandpass filter made by utilizing the piezoelectric effect of piezoelectric quartz crystal oscillator materials such as piezoelectric ceramics, lithium niobate, quartz and aluminum nitride and the physical characteristics of surface acoustic wave propagation. Compared with SAW filters, BAW filters are more suitable for high frequencies. Like SAW filters, the size of BAW filters also decreases with increasing frequency. In addition, BAW filters have the advantages of being insensitive to temperature changes, having low insertion loss, and having large out-of-band attenuation. FBAR filters are different from previous filters in that they are manufactured using silicon substrates and thin film technology. At this stage, FBAR filters already have characteristics slightly higher than ordinary SAW filters.

[0059] Among them, the low noise amplifier is an amplifier with a very low noise factor. It is generally used as a high-frequency or intermediate-frequency preamplifier for various radio receivers, as well as an amplifier circuit for highly sensitive electronic detection equipment. When amplifying weak signals, the noise of the amplifier itself may seriously interfere with the signal, so it is hoped to reduce this noise to improve the output signal-to-noise ratio.

[0060] In the embodiment of the present application, the first signal enhancement component 151 and the second signal enhancement component 152 have the same structure, which will not be described in detail. In other embodiments, the first signal enhancement component 151 and the second signal enhancement component 152 may also have different structures, which will not be limited here.

[0061] In another embodiment, the foldable electronic device 10 includes a first housing 11, a second housing 12, a hinge mechanism 13, a display screen 19, a first antenna 141, and a second antenna 142. The foldable electronic device 10 includes a first signal enhancement component 151, a second signal enhancement component 152, and a combiner 181. The first signal enhancement component 151 is arranged between the combiner 181 and the first antenna 141, and the second signal enhancement component 152 is arranged between the combiner 181 and the second antenna 142. In a wireless mobile phone communication system, the main function of the combiner is to combine the input multi-band signals together and output them to the same indoor distribution system. In engineering applications, it is necessary to output 800MHz network, 900MHz network or other different frequencies at the same time. By using a combiner, an indoor distribution system can work simultaneously in the CDMA frequency band, the GSM frequency band or other frequency bands. For example, in a radio antenna system, after the input and output signals of several different frequency bands are combined by a combiner, the signal is output using a feeder.

[0062] Different from the previous embodiment, the combiner 181 in the embodiment of the present application replaces the antenna selection switch 181 in the previous embodiment. The combiner 181 is used to combine at least two input signals into one signal to obtain a combined signal, and input the combined signal as an output signal into the communication chip 16 for the next signal processing. The embodiment of the present application combines two signals into one signal through the combiner 181, thereby improving the signal quality.

[0063] See also Figure 6 , Figure 6 It is a structural schematic diagram of the third embodiment of the foldable electronic device provided in the embodiments of the present application when it is in an unfolded state.

[0064] In the embodiment of the present application, the foldable electronic device 10 includes a first housing 11, a second housing 12, a hinge mechanism 13, a display screen 19, a first antenna 141, and a second antenna 142. The first housing 11 and the second housing 12 are two rotatable components of the foldable electronic device 10. The first housing 11 and the second housing 12 are connected by a hinge mechanism 13. The first antenna 141 and the second antenna 142 are both used for transmitting and receiving antenna signals, the first antenna 141 is arranged in the first housing 11, and the second antenna 142 is arranged in the second housing 12. When the foldable electronic device 10 is in an unfolded state, the display surface of the first screen body 191 and the display surface of the second screen body 192 are located in the same plane, and the maximum radiation direction of the first antenna 141 is the direction in which the first housing 11 is away from the hinge mechanism 13. When the foldable electronic device 10 is in a folded state, the display surface of the first screen body 191 and the display surface of the second screen body 192 are arranged opposite to each other, and the maximum radiation direction of the second antenna 142 is the direction in which the hinge mechanism 13 is away from the second housing 12.

[0065] The foldable electronic device 10 includes a first signal enhancement component 151 and an antenna selection switch 181. The antenna selection switch 181 is used to process the first antenna signal received by the first antenna 141 and the second antenna signal received by the second antenna 142 into one signal. The first signal enhancement component 151 enhances the one-way signal output by the antenna selection switch 181 to obtain an output signal. The output signal is finally input into the communication chip 16.

[0066] In an optional implementation, the antenna selection switch 181 is a radio frequency switch, and the antenna selection switch 181 is used to determine one of the at least two input signals as an output signal. Specifically, the first antenna 141 and the second antenna 142 are both global positioning system (GPS) antennas, and the first antenna signal and the second antenna signal are GPS signals. The antenna selection switch 181 obtains the carrier-to-noise ratio of the first antenna signal and the second antenna signal, and inputs the signal with a higher carrier-to-noise ratio in the first antenna signal and the second antenna signal into the first signal enhancement component 151 for enhancement processing to obtain an output signal.

[0067] In the present application, the signal processing module first processes the signals of the two antennas into one signal, and then only one signal enhancement module is needed to enhance the signal to obtain an output signal, which can reduce the number of signal enhancement modules, reduce the loss of the foldable electronic device 10 during use, and reduce the manufacturing cost of the foldable electronic device 10.

[0068] In another embodiment, the foldable electronic device 10 includes a first shell 11, a second shell 12, a hinge mechanism 13, a display screen 19, a first antenna 141 and a second antenna 142. The foldable electronic device 10 includes a first signal enhancement component 151 and a combiner 181. Different from the previous embodiment, the combiner 181 in the embodiment of the present application replaces the antenna selection switch 181 of the previous embodiment. The combiner 181 is used to combine at least two input signals into one signal to obtain a combined signal, and input the combined signal as an output signal into the communication chip 16 for the next signal processing. The embodiment of the present application combines two signals into one signal through the combiner 181, thereby improving the signal quality.

[0071] Specifically, it is detected whether the foldable electronic device is in a folded state, and if the foldable electronic device is in a folded state, a first antenna signal of the first antenna and a second antenna signal of the second antenna are obtained. If the foldable electronic device is not in a folded state, the second antenna is turned off.

Specifically, the first antenna and the second antenna are both global positioning system (GPS) antennas, and the first antenna signal and the second antenna signal are GPS signals. The signal performance index is the carrier-to-noise ratio of the antenna signal, and the signal with the higher carrier-to-noise ratio of the first antenna signal and the second antenna signal is determined as the output signal.
