Description

Foldable electronic device

[0001] The present application claims priority from the Chinese patent application No. 202410536195.5 filed on April 29, 2024, and entitled "Foldable electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a foldable electronic device. BACKGROUND

[0003] Foldable electronic devices can switch between different forms, integrating the advantages of large-screen display and small size and portability, and can meet various use scenarios, thus being favored by consumers. With the increasing maturity of folding technology, folding phones and other terminals are gradually gaining ground in the market.

[0004] Electronic devices are equipped with satellite communication antennas for satellite communication, carrying functions such as making and receiving calls and / or data transmission. The receiver of a foldable electronic device is generally provided at the top of one of the housings. When the satellite communication antenna is arranged near the receiver and the user selects to use the receiver mode for communication, the human body is close to the satellite communication antenna, for example, in a head-hand scenario where the user holds the electronic device and the head is close to or close to the electronic device, the absorption rate of the human body to the antenna energy is high. In order to control the radiation of the device to the human body within the standard range, it is usually necessary to take measures to reduce the antenna emission power to reduce the absorption of the human body to the antenna energy. However, after reducing the emission power of the satellite communication antenna, the energy radiated into the sky by the satellite communication antenna will also be reduced, which ultimately reflects in the decline of communication quality and the occurrence of signal interruption and other problems.

[0005] Therefore, how to improve the communication quality of the satellite communication antenna of the foldable electronic device in the head-hand scenario is a problem to be solved. SUMMARY

[0006] The foldable electronic device provided by the embodiments of the present application improves the communication quality of the satellite communication antenna thereof in the head-hand scenario.

[0007] The embodiments of the present application provide a foldable electronic device, which includes a housing assembly, the housing assembly includes at least two housings arranged in sequence, and the adjacent two housings are rotationally connected through a rotating shaft mechanism. The foldable electronic device further includes a first satellite communication antenna, a second satellite communication antenna, a radio frequency module, a processor, and a receiver.

[0008] The first satellite communication antenna comprises a first radiator, the second satellite communication antenna comprises a second radiator, the first radiator and the second radiator each have a feed point, the radio frequency module is configured to transmit signals of a satellite communication frequency band to the feed point of the first radiator and the feed point of the second radiator, and the processor is in communication connection with the radio frequency module and is configured to determine one of the first satellite communication antenna and the second satellite communication antenna as a transmitting antenna.

[0009] In addition, the at least two housings comprise a first housing and a second housing, the first radiator of the first satellite communication antenna and the earpiece are arranged on the top of the first housing, and the second radiator of the second satellite communication antenna is arranged on the upper half of the second housing.

[0010] When the earpiece is closed, the first satellite communication antenna works as the transmitting antenna. When the earpiece is opened, the second satellite communication antenna works as the transmitting antenna.

[0011] The foldable electronic device provided in the embodiments has a first housing and a second housing, the first housing and the second housing are different housings and can be folded or unfolded with each other. Satellite communication antennas are arranged on the two housings, and the satellite communication antennas on each housing can transmit signals of a satellite communication frequency band, so that one of the satellite communication antennas on the housings can be selectively used as a transmitting antenna according to different scenes, that is, the satellite communication antenna on one of the housings is selectively used for satellite communication.

[0012] The first radiating body of the first satellite communication antenna is located at the top of the first shell, and the position is provided with an earpiece. The second radiating body of the second satellite communication antenna is located at the upper half of the second shell. On the one hand, the first satellite communication antenna and the second satellite communication antenna are both located at the upper half of the shell, and the satellite communication antennas on the two shells are both directed to the sky when the user holds the device, which is beneficial to the signal radiation of the satellite communication frequency band. On the other hand, in the normal scenario of the closed earpiece (for example, in the scenarios of data transmission, intercom call mode, Bluetooth call mode, etc.), at this time, the user is far away from the device, and the radiation of the antenna to the human body is low. The first satellite communication antenna is used for satellite communication, and the performance of the first satellite communication antenna is generally better due to the influence of the GPS antenna position, which ensures the communication quality. When the earpiece is opened, for example, in the special head-hand scenario of using the earpiece mode to call, the user usually folds the device for use, holds the lower half of the device, and the head is close to the earpiece on the first shell. The second satellite communication antenna is selected for satellite communication. After folding, the second satellite communication antenna is farther away from the head, and the radiation of the second satellite communication antenna to the human body is lower than that of the first satellite communication antenna. The radiation of the second satellite communication antenna to the human body can be controlled within the standard range without reducing the transmission power of the second satellite antenna. Moreover, the antenna energy absorbed by the human body is less, and the energy radiated outward by the antenna is more, so that the communication quality can be ensured.

[0096] It can be understood by those skilled in the art that the shell assembly is used to carry and accommodate the first display screen 81, the second display screen 82 and other electronic components, and the specific structure is not limited. As shown in FIG. 1 and FIG. 3, in an embodiment, the first shell 11 includes a frame 111 and a bottom plate 112, wherein the frame 111 is a frame structure arranged circumferentially around the bottom plate 112, the bottom plate 112 is fixedly connected with the frame 111, and the first part 811 of the first display screen 81 and the second display screen 82 are arranged on both sides of the bottom plate 112 in the thickness direction Z1 of the first shell.

[0098] As shown in FIG. 3, in an embodiment, the foldable electronic device 100 further comprises a first camera module 71 disposed on the second housing 12, which has one or more lenses (four lenses are taken as an example in the figure, and the number of lenses in the first camera module 71 is not limited in the present application), the lenses pass through the back cover 122 of the second housing 12 and are exposed outside the second housing 12, carrying the light-in function of the first camera module 71. In an embodiment, the foldable electronic device 100 further comprises a second camera module 72 disposed on the top of the first housing 11 and facing the second display screen 82. It should be understood that when a user holds the foldable electronic device 100 (for example, the user holds the electronic device and unlocks, or for example, the user holds the electronic device vertically and faces the screen), the orientation of the foldable electronic device 100 has a top and a bottom, the side facing the sky is the top, and the side facing the ground is the bottom. It should be noted that the top of the foldable electronic device 100 not only refers to one side facing the sky, but also can include a part of the area where the side is located, for example, the top frame of the foldable electronic device and the accommodating cavity close to the top frame, and the bottom of the foldable electronic device 100 is the same. Further, each display screen and each housing of the foldable electronic device 100 also has a top and a bottom. For example, when the user holds the foldable electronic device 100, the side of the second display screen 82 facing the sky (the upper side in FIG. 3) is the top of the second display screen 82, and the side facing the ground (the lower side in FIG. 3) is the bottom of the second display screen 82. The top and bottom of each housing mentioned hereinafter can also be understood in the same way, which will not be repeated here.

The second camera module 72 is the front camera module of the foldable electronic device 100, which can be used for self-portrait when the user faces the second display screen 82.

[0099] It can be understood by those skilled in the art that the foldable electronic device 100 generally has one or more circuit boards (not shown in the figure), wherein the circuit board with the most devices and the largest layout area is the main circuit board, and the others are auxiliary circuit boards. The main circuit board is connected with each auxiliary circuit board and carries the core computing function of the foldable electronic device 100. Generally, the main circuit board is arranged in the second housing 12, which can shorten the wiring distance between the first camera module 71 and the main circuit board and shorten the transmission loss. The auxiliary circuit board can be arranged in other housings and can be connected with the main circuit board through a device such as an FPC (Flexible Printed Circuit). It should be noted that the auxiliary circuit board can also be arranged in the second housing 12, that is, the second housing 12 and / or other housings can be provided with auxiliary circuit boards. Therefore, the second housing 12 where the first camera module 71 and the main circuit board are located is also called the main frame of the foldable electronic device 100, and the first housing 11 where the second display screen 82 is located is also called the auxiliary frame of the foldable electronic device 100. It should be noted that the structure of the foldable electronic device 100 described above is only schematic, and the electronic device provided in the present application can include more or fewer devices than in the figures and the above description, which is not limited in the present application.

[0100] The foldable electronic device 100 can also be provided with various antennas, different types of antennas are used to receive and transmit different signals, and various types of antennas are collected together to ensure that the foldable electronic device 100 has complete communication functions. For example, a satellite communication antenna is used to receive and transmit signals in a satellite communication frequency band, mainly supporting satellite communication (such as making and receiving calls) and data transmission services (such as browsing the web, receiving broadcasts, playing network videos, etc.) of the foldable electronic device 100. The GPS (Global Positioning System) antenna can receive and transmit signals in the GPS frequency band, mainly used for positioning. The cellular antenna is a kind of antenna used for terrestrial communication, which integrates 2G, 3G, 4G, 5G and other multi-band communication networks. In addition, the foldable electronic device 100 can also be equipped with MHB (Middle High Band) antennas, LB (Low Band) antennas, etc., to realize comprehensive coverage of communication networks. The type, number and setting position of the antennas in the foldable electronic device 100 are not limited in the present application. Among them, in an embodiment, the signals in the satellite communication frequency band may, for example, include part of the frequency band in the Tianhong satellite system, and can include the transmission frequency band (1980-2010 MHz) and the receiving frequency band (2170-2200 MHz) in the Tianhong satellite system. In an embodiment, the satellite communication frequency band can include part of the transmission frequency band (1610-1626.5 MHz) and the receiving frequency band (2483.5-2500 MHz) in the Beidou satellite system. In an embodiment, the satellite communication frequency band can include part of the transmission frequency band (1668-1675 MHz) and the receiving frequency band (1518-1525 MHz) in the low-orbit satellite system, which is not limited in the present application.

[0101] The positions of different antennas in the foldable electronic device 100 directly affect the radiation efficiency of the antennas and the coupling strength between different antennas. For a satellite communication antenna, it should be directed to the sky during operation, and can more efficiently radiate signals to the satellite in the sky. Therefore, the satellite communication antenna is generally arranged at the top of the foldable electronic device 100. In addition, considering the layout of various antennas in the foldable electronic device 100, the satellite communication antenna is preferably arranged at the top 113a of the sub-frame (i.e., the first housing 11). However, the top 113a of the sub-frame generally also has an earpiece (for example, the earpiece 61 in FIG. 6a). When the user selects to use the earpiece mode for communication, the human head is close to the satellite communication antenna, that is, the head-hand scenario of "holding the electronic device with the hand and the head close to or close to the electronic device", and the absorption rate of the human body to the antenna energy is high. In order to control the radiation of the device to the human body within the standard range, it is generally necessary to take measures to reduce the transmission power of the antenna to reduce the absorption of the human body to the antenna energy. However, after reducing the transmission power of the satellite communication antenna, the energy radiated to the sky will also be reduced, and the efficiency will also be lower, which ultimately reflects the decline in communication quality and the occurrence of signal interruption and other problems. Therefore, how to improve the communication quality of the satellite communication antenna of the foldable electronic device in the head-hand scenario is a problem to be solved.

[0102] To solve the above problems, the application creatively proposes an improved scheme which can ensure the quality of satellite communication in various use scenarios. The improved scheme of the application will be described below in conjunction with the drawings.

[0103] Please refer to FIGS. 5-6d, FIG. 5 is a schematic diagram of a first embodiment of a satellite communication system in a foldable electronic device according to the application; FIGS. 6a-6b are schematic diagrams of the position of a satellite communication antenna in a foldable electronic device according to the application, wherein FIG. 6a shows the foldable electronic device in an open state, and FIG. 6b shows the foldable electronic device in a folded state; FIG. 6c is a circuit schematic diagram one of a radio frequency module in a foldable electronic device according to the application; and FIG. 6d is a circuit schematic diagram two of a radio frequency module in a foldable electronic device according to the application.

[0104] As shown in FIGS. 5-6b, the foldable electronic device 100 further includes a first satellite communication antenna 2, a second satellite communication antenna 3, a radio frequency module, a processor 62, and an earpiece 61. The first satellite communication antenna 2 and the second satellite communication antenna 3 are both used for satellite communication, and the radio frequency module is used to transmit signals of a satellite communication frequency band to the first satellite communication antenna 2 and the second satellite communication antenna 3. It should be noted that the specific number of each satellite communication antenna and the radio frequency module is not limited, and can be one or more.

[0105] The processor 62 is responsible for executing instructions of an operating system and application programs, and can perform data processing and calculation.

Different processing units can be independent devices or integrated together, which are not limited in the present application. In an embodiment, the processor 62 can be a system on chip (SOC), which is an integrated circuit that integrates a computing processor 62 and other electronic systems into a single chip. In other alternative embodiments, the processor 62 can also adopt other types, which are not limited in the present application.

[0106] It should be noted that the position of the processor 62 is not limited and can be arranged on the first housing 11 or the second housing 12. When other housings are also arranged in the foldable electronic device 100, the processor 62 can also be arranged on the other housings. As shown in FIG. 6a, in an embodiment, the first camera module 71 and the processor 62 are arranged on the second housing 12, and the first camera module 71 is in communication connection with the processor 62. It can be understood that the first camera module 71 is a main camera module, which includes a large number of cameras and has high resolution. Arranging the processor 62 and the first camera module 71 on the same housing can shorten the transmission line between them, support high-speed transmission of photographic data, and support complex analysis and operation. Specifically, in an embodiment, the processor 62 includes an application processing unit 621, and the application processing unit 621 is in communication connection with the first camera module 71.

[0107] The earpiece 61 is a sound emitting device, mainly functions to receive and transmit sound during a call, and also protects the privacy of the user. When receiving a call or playing private voice, the user can only hear the voice of the other party when the ear is close to the earpiece 61 during the call, so the privacy is relatively strong. The earpiece 61 is arranged in the top area of the foldable electronic device 100, for example, arranged at the top of the accommodation space in the first housing 11, which is not limited in the present application. The foldable electronic device 100 can also be provided with a loudspeaker, the sound of the loudspeaker is large, and the user can hear the sound emitted by the loudspeaker in a certain space. The loudspeaker can be used to play audio and video, or to make a call in a walkie-talkie mode, and the user's head does not need to be close to the earpiece 61. In addition, the foldable electronic device 100 can also be provided with a Bluetooth module, and the user can connect a Bluetooth headset for voice communication, which is not limited in the present application.

[0108] Further, the first satellite communication antenna 2 includes a first radiator 21, the second satellite communication antenna 3 includes a second radiator 31, the first radiator 21 and the second radiator 31 each have a feed point, the radio frequency module is configured to transmit signals of a satellite communication frequency band to the feed point 210 of the first radiator 21 and the feed point 310 of the second radiator 31, and the processor 62 is in communication connection with the radio frequency module and is configured to determine one of the first satellite communication antenna 2 and the second satellite communication antenna 3 as a transmitting antenna. It should be noted that the present application does not limit the specific position of the feed point on each antenna radiator, which can be located at the end of the radiator or between the two ends, and the figure is only schematic. Among them, the communication connection can be through circuit connection, or coupling connection, which is not limited in the present application.

[0109] It should be noted that the number and form of the radiators in each satellite communication antenna are not limited. The first radiator 21 can be understood as the main feed radiator of the first satellite communication antenna 2, and the second radiator 31 can be understood as the main feed radiator of the second satellite communication antenna 3. In addition to the main feed radiator, each satellite communication antenna can also support the receiving / transmitting frequency band of the satellite communication antenna through coupling or electrical connection with other radiators (such as other parts of the shell frame), such as setting a parasitic radiator, or through a capacitively connected adjacent radiator. As long as the main feed radiators of the first satellite communication antenna 2 and the second satellite communication antenna 3 meet the positional relationship in the embodiments of the present application, they are within the protection scope of the present scheme.

[0110] It should be noted that the radio frequency modules of the satellite communication antennas can be separately arranged or shared, and the present application does not limit this. As shown in FIG. 6a, in an embodiment, the radio frequency modules include a first radio frequency module 22 and a second radio frequency module 32, the first radio frequency module 22 is used to transmit signals of a satellite communication frequency band to the feed point 210 of the first radiator 21, and the second radio frequency module 32 is used to transmit signals of a satellite communication frequency band to the feed point 310 of the second radiator 31. Each radio frequency module may, for example, be a radio frequency chip or the like, and the present application does not limit its specific form. In an embodiment, a first power amplifier 641 is arranged between the first radio frequency module 22 and the feed point 210 of the first radiator 21, and a second power amplifier 642 is arranged between the second radio frequency module 32 and the feed point 310 of the second radiator 31. The power amplifier can increase the power of the input signal to a higher level, so as to maintain the strength and quality of the signal during transmission. Each power amplifier may, for example, be a PA (Power Amplifier) or the like, and the present application does not limit this. The positions of each radio frequency module and power amplifier are not limited, and in an embodiment, the first radio frequency module 22 and the first power amplifier 641 are both arranged in the first shell 11, and the second radio frequency module 32 and the second power amplifier 642 are both arranged in the second shell 12, so as to shorten the connection line between each satellite communication antenna and the radio frequency module and reduce transmission loss.

[0111] As shown in FIG. 6c, in an alternative embodiment, the radio frequency modules include a first radio frequency module 22, the first radio frequency module 22 is arranged in the first shell 11 and is used to transmit signals of a satellite communication frequency band to the feed point 210 of the first radiator 21 and the feed point 310 of the second radiator 31. A first power amplifier 641 is arranged between the first radio frequency module 22 and the feed point 210 of the first radiator 21, and the first power amplifier 641 is arranged in the first shell. A second power amplifier 642 is arranged between the first radio frequency module 22 and the feed point 310 of the second radiator 31, and the second power amplifier 642 is arranged in the second shell 12. As shown in FIG. 6d, in an alternative embodiment, the radio frequency modules include a second radio frequency module 32, the second radio frequency module 32 is arranged in the second shell 12 and is used to transmit signals of a satellite communication frequency band to the feed point 210 of the first radiator 21 and the feed point 310 of the second radiator 31. A first power amplifier 641 is arranged between the second radio frequency module 32 and the feed point 210 of the first radiator 21, and the first power amplifier 641 is arranged in the first shell 11. A second power amplifier 642 is arranged between the second radio frequency module 32 and the feed point 310 of the second radiator 31, and the second power amplifier 642 is arranged in the second shell 12.

[0112] In an embodiment, the processor 62 comprises a signal processing unit 622, which is communicatively connected with the first radio frequency module 22 and the second radio frequency module 32 respectively. The signal processing unit 622 undertakes signal processing and conversion functions, which can specifically include signal acquisition, filtering, amplification, noise reduction, etc., as well as data compression and encryption. After the signal transmission of the radio frequency module to the signal processing unit 622, the signal can be converted into image, sound, etc. information, and vice versa, the image and sound information can be converted by the signal processing unit 622 into signal transmission to the radio frequency module, which is sent to the corresponding satellite communication antenna after being processed by the radio frequency module.

[0113] Further, the first radiating body 21 of the first satellite communication antenna 2 and the earpiece 61 are arranged on the top 113a of the first housing 11, and the first radio frequency module 22 is arranged in the first housing 11. The second radiating body 31 of the second satellite communication antenna 3 is arranged on the upper half of the second housing 12, and the second radio frequency module 32 is arranged in the second housing 12. Wherein, the upper half of the second housing 12 comprises the top 123a of the second housing 12. Or it can be understood that, taking the middle axis O of the foldable electronic device 100 as the dividing line (the middle axis O is perpendicular to the length direction Y of the rotation shaft mechanism), the second housing 12 is divided into upper and lower two parts, and the part where the top 123a is located is the upper half, and the part where the bottom 123b is located is the lower half. The upper half and the lower half of other housings in the foldable electronic device 100 can also be understood in the same way, and details are not repeated here.

[0114] The foldable electronic device 100 provided by the embodiments of the present application has a first housing 11 and a second housing 12, which are different housings and can be folded with each other. Satellite communication antennas and corresponding radio frequency modules are arranged on the two housings, and the satellite communication antennas on each housing can emit signals of satellite communication frequency bands, so that the satellite communication antenna on one of the housings can be selectively used as a transmitting antenna according to different scenes, i.e. the satellite communication antenna on one of the housings is selectively used for satellite communication.

[0115] The first radiating body 21 of the first satellite communication antenna 2 is located at the top 113a of the first shell 11, and the second radiating body 31 of the second satellite communication antenna 3 is located at the upper half of the second shell 12. On the one hand, the first satellite communication antenna 2 and the second satellite communication antenna 3 are both located at the upper half of the shell, and the satellite communication antennas on the two shells are both directed to the sky when the user holds the device, which is conducive to the outward radiation of the satellite communication frequency band. On the other hand, in the data transmission, intercom mode, Bluetooth mode and other scenarios, the user's head is far away from the device, and the radiation of the antenna to the human body is low in itself. According to the arrangement of various antennas in the specific product, the satellite communication antenna with better performance can be selected as the transmitting antenna (generally, the performance of the first satellite communication antenna 2 is better due to the influence of the GPS antenna position). In the special head-hand scenario such as using the earpiece 61 mode to talk, the user usually folds the device for use, holds the lower half of the device and the head close to the earpiece 61 on the first shell 11. At this time, the second satellite communication antenna 3 can be selected for satellite communication. After folding, the second satellite communication antenna 3 is farther away from the head, and the radiation to the human body is lower than that of the first satellite communication antenna 2. Therefore, the second satellite antenna 3 can control the radiation to the human body within the standard range without reducing the transmitting power. Moreover, the human body absorbs less antenna energy, and the antenna radiates more energy outward, thereby ensuring the communication quality.

[0116] Therefore, the foldable electronic device 100 provided by the embodiment of the present application improves the communication quality of the satellite communication antenna in the head-hand scenario.

[0117] Please refer to FIG. 7, which is a selection logic diagram of the satellite communication antenna in the foldable electronic device of the embodiment of the present application.

[0118] As shown in FIGS. 6a-7, in one embodiment, when the earpiece 61 is closed, the first satellite communication antenna 2 works as a transmitting antenna. When the earpiece 61 is opened, the second satellite communication antenna 3 works as a transmitting antenna. Since the processor 62 of the foldable electronic device 100 is arranged on the second housing 12, the processor 62 generates a large amount of heat when working, and the satellite communication antenna also generates heat when working, so generally the commonly used satellite communication antenna is arranged on a different housing from the processor 62 to avoid heat concentration. Moreover, when the GPS antenna is close to the satellite communication antenna, the GPS antenna will be coupled with the satellite communication antenna, affecting the antenna efficiency. Therefore, generally the GPS antenna is arranged in the upper half area of the main frame (for example, the position of the GPS antenna 51 in FIG. 17), and the second satellite communication antenna 3 at the top 123a of the main frame is close to the GPS antenna, which is easy to be coupled, and the comprehensive performance of the first satellite communication antenna 2 is better than that of the second satellite communication antenna 3. In the normal scenario where the earpiece 61 is closed, the first satellite communication antenna 2 is used for satellite communication, at this time the human body does not need to be close to the foldable electronic device 100, the absorption rate of the antenna energy is low, and the antenna radiates more energy outward, which can ensure the communication quality. In the special scenario (for example, head-hand) where the earpiece 61 is opened, the second satellite communication antenna 3 is used as a transmitting antenna, at this time the user generally folds the device for use, the second satellite communication antenna 3 is far away from the head, and the radiation to the human body is lower than that of the first satellite communication antenna, so it is not necessary to reduce the transmitting power of the second satellite antenna to control the radiation to the human body within the standard range. Moreover, the human body absorbs less antenna energy, and the antenna radiates more energy outward, so the communication quality can be ensured.

[0119] As shown in FIG. 7, in one example scenario, the logic of the foldable electronic device 100 switching the satellite communication antenna can be: judging whether to use satellite communication according to the service state, if it is a service such as voice call or data transmission, satellite communication can be selected, and if it is other service, other communication mode such as cellular communication can be used. Further, judging the service type of the satellite communication, if it is ordinary data service, the first satellite communication antenna 2 is selected as a transmitting antenna. If it is language service, it is further judged whether the earpiece 61 is opened, and the first satellite communication antenna 2 is used as a transmitting antenna when the earpiece 61 is closed, and the second satellite communication antenna 3 is switched as a transmitting antenna when the earpiece 61 is opened.

[0120] Among them, the opening and closing of the earpiece 61 need corresponding trigger signals, which can be selected by the user, for example, clicking on the screen to open or close the earpiece 61 (or clicking to select to open or close the loudspeaker), or generated by other devices, which is not limited in the present application.

[0121] In one embodiment, when the earpiece 61 is closed and a first trigger signal is generated, the processor 62 controls the first radio frequency module 22 to send signals of satellite communication frequency band to the feed point 210 of the first radiator 21, so that the first satellite communication antenna 2 works as a transmitting antenna in response to the first trigger signal. When the earpiece 61 is opened and a second trigger signal is generated, the processor 62 controls the second radio frequency module 32 to send signals of satellite communication frequency band to the feed point 310 of the second radiator 31, so that the second satellite communication antenna 3 works as a transmitting antenna in response to the second trigger signal.

[0122] In an alternative embodiment, the foldable electronic device 100 can further comprise a trigger device (not shown in the figure). When the trigger device generates a first trigger signal, the processor 62 controls the first radio frequency module 22 to send signals of satellite communication frequency band to the feed point 210 of the first radiator 21, so that the first satellite communication antenna 2 works as a transmitting antenna in response to the first trigger signal. When the trigger device generates a second trigger signal, the processor 62 controls the second radio frequency module 32 to send signals of satellite communication frequency band to the feed point 310 of the second radiator 31, so that the second satellite communication antenna 3 works as a transmitting antenna in response to the second trigger signal. The trigger device can be, but is not limited to, a proximity light sensor or an ambient light sensor or a distance sensor, wherein the trigger device generates the first trigger signal when the trigger device is away from an object, and the trigger device generates the second trigger signal when the trigger device is blocked by the object. In one example scenario, the trigger device is an ambient light sensor, which can be arranged near the earpiece 61. When the user's head is close to the earpiece 61, the ambient light sensor is blocked and the amount of incoming light decreases, thereby generating the second trigger signal to make the second satellite communication antenna 3 work. When the user's head is away from the earpiece 61, the amount of incoming light is larger, generating the first trigger signal to make the first satellite communication antenna 2 work.

[0125] As shown in FIG. 6a-FIG. 6b, in one embodiment, the second radiating body 31 of the second satellite communication antenna 3 is arranged on the frame 121 of the second housing 12 and located at the top 123a of the second housing 12.

[0126] As shown in FIG. 8a-FIG. 8b, in an alternative embodiment, the second radiating body 31 can also be arranged on the side frame of the second housing 12, and the second radiating body 31 can also efficiently receive and transmit signals of the satellite communication frequency band on the side of the upper half of the second housing 12. It should be noted that the first radiating body 21 and the second radiating body 31 can both be directly formed by the frame of the housing, for example, the antenna slots are directly processed on the frame made of metal material to form the radiating bodies of the antennas, or the patch structure is attached to the frame, and the present application does not limit this.

[0127] As shown in FIGS. 9a-11, in an embodiment, the second radiator 31 can also be arranged on the rear cover 122 of the second housing 12. The specific position of the second radiator 31 on the rear cover 122 is not limited, as long as it is located on the upper half of the rear cover 122, for example, above the first camera module 71 and away from the rotation shaft mechanism 14 (as shown in FIGS. 9a-9b), above the first camera module 71 and close to the rotation shaft mechanism 14 (as shown in FIG. 10), between the first camera module 71 and the rotation shaft mechanism 14 (as shown in FIG. 11), etc. The second satellite communication antenna 3 can be a rear cover antenna, a bracket antenna, a patch antenna, etc., which is not limited in the present application. In an embodiment, the second radiator 31 is formed by the rear cover 122 of the second housing 12, i.e., arranged as a rear cover antenna, and the second radiator 31 is directly processed on the metal part of the second housing 12.

[0129] Those skilled in the art can understand that when the satellite communication antenna works as a transmitting antenna, its radiator can transmit signals to the satellite, and the communication is mutual, and a receiving antenna is also needed to receive signals, and the first satellite communication antenna 2 and the second satellite communication antenna 3 can both work as receiving antennas. When the first satellite communication antenna 2 works as a transmitting antenna, signals can be received by only the first satellite communication antenna 2 (signals of the satellite communication frequency band can be transmitted to the radio frequency module), signals can be received by the first satellite communication antenna 2 and the second satellite communication antenna 3 at the same time (signals of the satellite communication frequency band can be transmitted to the radio frequency module by the first satellite communication antenna 2 and the second satellite communication antenna 3), or signals can be received by only the second satellite communication antenna 3 (signals of the satellite communication frequency band can be transmitted to the radio frequency module), or signals of the satellite communication frequency band can be received by other radiators. When the second satellite communication antenna 3 works as a transmitting antenna, the radiators for receiving signals of the satellite communication frequency band are also not limited, and signals of the satellite communication frequency band can be received by only the second satellite communication antenna 3, signals of the satellite communication frequency band can be received by only the first satellite communication antenna 2, signals of the satellite communication frequency band can be received by the first satellite communication antenna 2 and the second satellite communication antenna 3 at the same time, or additional radiators can be arranged to receive signals of the satellite communication frequency band to enhance the ability of the foldable electronic device 100 to receive signals of the satellite communication frequency band.

[0130] It should be noted that when each satellite communication antenna works as a transmitting antenna and a receiving antenna, the receiving and transmitting of signals of the satellite communication frequency band can be synchronous or asynchronous, and the present application does not limit this. For example, different frequency bands of signals can be transmitted and received at the same time (the signal paths of different frequency bands of signals are different), that is, frequency division, or signals can be transmitted and received in different time periods, that is, time division (time is divided into a plurality of non-overlapping time periods, and each signal occupies one time period).

[0131] Please refer to FIGS. 13-16a-16b, FIG. 13 is a schematic diagram of the principle of a second embodiment of a satellite communication system in the foldable electronic device according to the present application; FIG. 14 is a schematic diagram of the position of a first embodiment of a third radiator in the foldable electronic device according to the present application; FIG. 15 is a schematic diagram of the principle of a third embodiment of a satellite communication system in the foldable electronic device according to the present application; and FIGS. 16a-16b are schematic diagrams of the position of a second embodiment of a third radiator in the foldable electronic device according to the present application.

[0132] As shown in FIG. 5, FIG. 13, in an embodiment, the first satellite communication antenna 2 also functions as a receiving antenna, and can send signals of a satellite communication frequency band to the first radio frequency module 22 through the feed point 210 of the first radiator 21. In an embodiment, the second satellite communication antenna 3 also functions as a receiving antenna, and can send signals of a satellite communication frequency band to the second radio frequency module 32 through the feed point 310 of the second radiator 31. As shown in FIG. 13-FIG. 14, in an embodiment, the foldable electronic device 100 further comprises a third satellite communication antenna 4, which functions as a receiving antenna and comprises a third radiator 41 having a feed point 410, and the third radiator 41 can send signals of a satellite communication frequency band to the first radio frequency module 22 through the feed point 210. At this time, the first radio frequency module 22 is a 1T2R radio frequency module (1 transmission, 2 receptions), and when the first satellite communication antenna 2 is working, the first radio frequency module 22 sends signals to the first radiator 21 and simultaneously receives signals from the first radiator 21 and the third radiator 41. With this structure, the signal receiving capability of the foldable electronic device 100 can be enhanced, and the voice of the other party during a call is clearer.

[0133] The third radiating body 41 of the third satellite communication antenna 4 can be separately arranged or multiplexed by other radiating bodies, which is not limited in the application. As shown in FIGS. 13-14, in an embodiment, the third radiating body 41 is arranged on the first shell 11. Arranging the third radiating body 41 on the first shell 11 can reduce the line loss between the third radiating body 41 and the first radio frequency module 22. Specifically, the third radiating body 41 can be arranged on the frame 111 of the first shell 11 (for example, on the side frame of the upper half of the first shell 11 in FIG. 14, which is conducive to receiving signals) or other positions, which is not limited in the application. As shown in FIGS. 15-16b, in an alternative embodiment, the second radiating body 31 of the second satellite communication antenna 3 further has an additional feeding point 311, the second radiating body 31 is multiplexed as the third radiating body 41, and the additional feeding point 311 is multiplexed as the feeding point 410 of the third radiating body 41. That is, the second radiating body 31 of the second satellite communication antenna 3 is multiplexed as the third radiating body 41 of the third satellite communication antenna 4, and when the first satellite communication antenna 2 is working, the first radio frequency module 22 transmits signals to the first radiating body 21 and simultaneously receives signals from the first radiating body 21 and the second radiating body 31. As shown in FIG. 16a, in an embodiment, a low-noise amplifier 63 is arranged between the additional feeding point 311 of the second radiating body 31 and the first radio frequency module 22. It can be understood that the line between the second radiating body 31 and the first radio frequency module 22 needs to pass through the rotating shaft mechanism 14, and the loss is large. Arranging the low-noise amplifier 63 between the second radiating body 31 and the first radio frequency module 22 can make up for this part of the loss of passing through the shaft. The low-noise amplifier 63 includes but is not limited to a low noise amplifier (LNA), which is not limited in the application.

[0134] The additional feeding point 311 and the feeding point 310 of the second radiating body 31 can be the same or different, which is not limited in the application. As shown in FIG. 16a, in an embodiment, the additional feeding point 311 and the feeding point 310 of the second radiating body 31 are different feeding points, and at this time, the two feeding points are connected with the corresponding radio frequency modules through respective circuits. As shown in FIG. 16b, in an alternative embodiment, the additional feeding point 311 and the feeding point 310 of the second radiating body 31 are the same feeding point, and at this time, a switch (for example, a single-pole double-throw switch) can be added in the feeding circuit to selectively connect the feeding point with the first radio frequency module 22 or the second radio frequency module 32 in communication.

[0135] Those skilled in the art can immediately understand that other types of antennas can also be arranged in the foldable electronic device 100, and the following is an example to illustrate the types and positions of the antennas that can be arranged.

[0136] Please refer to FIG. 17-FIG. 19, FIG. 17 is a schematic diagram of the position of the GPS antenna in the foldable electronic device according to the embodiments of the present application; FIG. 18 is a schematic diagram of the position of the cellular antenna in the foldable electronic device according to the embodiments of the present application; FIG. 19 is a schematic diagram of the position of the cellular antenna in the foldable electronic device according to the embodiments of the present application.

[0137] As shown in FIG. 17, in one embodiment, the foldable electronic device 100 further comprises a GPS antenna 51. The number of the GPS antenna 51 is not limited, which can be one, two, three or more. The GPS antenna 51 has a fourth radiator 511, at least a part of which along its extension direction is arranged on the top 123a of the second housing 12. The GPS antenna 51 can support the positioning of the foldable electronic device 100, and the GPS antenna 51 transmits signals (for example, 1227.6MHz-1575.42MHz) of the GPS communication frequency band with the GPS satellite. Arranging at least a part of the structure of the fourth radiator 511 of the GPS antenna 51 on the top 123a of the second housing 12 can improve its signal transceiving capability. Wherein, the GPS antenna 51 can only have a part arranged on the top 123a of the second housing 12, or can be arranged entirely on the top 123a of the second housing 12, which is not limited by the present application. Since the top 123a of the second housing 12 is provided with the second satellite communication antenna 3, the distance between the GPS antenna 51 and the second satellite communication antenna 3 is relatively close, and the two are easy to be coupled, which leads to the decrease of the efficiency of the second satellite communication antenna 3, so in the normal mode of the non-head-hand, the first satellite communication antenna 2 is generally selected as the transmitting antenna. In an alternative embodiment, the fourth radiator 511 of the GPS antenna 51 can also be arranged on the side of the upper half of the second housing 12, which is not limited by the present application.

[0138] As shown in FIG. 18, in an embodiment, the foldable electronic device 100 further includes at least one first cellular antenna 52, for example, 1, 2, 3, etc., without limitation. The first cellular antenna 52 has a fifth radiator 521 provided with a feed point. In an embodiment, the fifth radiator 521 of the first cellular antenna 52 is disposed on the frame 111 of the first housing 11. Specifically, the fifth radiator 521 of the first cellular antenna 52 can be located on the bottom 113b (as shown in FIG. 18), the top 113a of the first housing 11, or the side frame of the first housing 11, without limitation. In an embodiment, the first cellular antenna 52 is in communication connection with the first radio frequency module 22, and the first radio frequency module 22 is configured to transmit signals of a cellular communication frequency band to the feed point on the fifth radiator 521. Without the need to additionally provide a radio frequency module for the first cellular antenna 52, the circuit structure of the foldable electronic device 100 can be simplified, and the production cost can be saved. It should be noted that the radio frequency module of the first cellular antenna 52 can also be shared with the radio frequency module of the first satellite communication antenna 2, without limitation.

[0139] As shown in FIG. 19, in an embodiment, the foldable electronic device 100 can further include at least one second cellular antenna 53, for example, 1, 2, 3, etc., without limitation. The second cellular antenna 53 has a sixth radiator 531 disposed on the second housing 12, without limitation on the specific position of the sixth radiator 531 on the second housing 12. The second cellular antenna 53 can also be in communication connection with the second radio frequency module 32, so as to simplify the circuit structure of the foldable electronic device 100 and save production cost.

[0140] The first cellular antenna 52 and the second cellular antenna can each include one or more of a 2G antenna (2-generation wireless telephone technology), a 3G antenna (3rd-generation), a 4G antenna (the 4th generation mobile communication technology), and a 5G antenna (5th generation mobile communication technology, also known as new radio, abbreviated as NR). The 2G antenna, the 3G antenna, and the 4G antenna can each include a middle and high band (MHB) antenna and a low band (LB) antenna, without limitation. The signals of the cellular communication frequency band can include 2G signals, 3G signals, 4G signals, 5G signals, etc., without limitation.

[0141] In one embodiment, the first cellular antennas 52 on the first housing 11 and the second cellular antennas 53 on the second housing 12 are one-to-one corresponding in number, position and type, so that the cellular antennas on the first housing 11 or the second housing 12 can be selectively used for the purpose of reducing the radiation of the cellular antennas to the human body or improving the cellular communication quality. For example, six first cellular antennas 52 are shown in FIG. 19, one of which is arranged on the top 113a of the first housing 11, one is arranged on the bottom 113b of the first housing 11, and the rest are arranged on the side frame of the first housing 11. Among the six first cellular antennas 52, four antennas include MHB antennas and NR antennas, and two antennas are LB antennas. Correspondingly, six second cellular antennas 53 are arranged on the second housing 12, and the types and positions of the six second cellular antennas 53 correspond to those of the six first cellular antennas 52 on the first housing 11. For example, when the user is far away from the foldable electronic device 100 (such as in data transmission, Bluetooth mode, walkie-talkie mode, etc.), the first cellular antennas 52 on the first housing 11 can be used for cellular communication, and when the user is close to the foldable electronic device 100 (such as in head and hand mode), the second cellular antennas 53 on the second housing 12 can be used for cellular communication.

[0142] In one embodiment, one of the six first cellular antennas 52 works as a transmitting antenna, and all or part of the six first cellular antennas 52 work as receiving antennas. One of the six second cellular antennas 53 works as a transmitting antenna, and all or part of the six second cellular antennas 53 work as receiving antennas. In other alternative embodiments, multiple first cellular antennas 52 and / or multiple second cellular antennas 53 can also work as transmitting antennas, which are not limited in the present application.

[0143] As shown in FIG. 19, in one embodiment, the first satellite communication antenna 2 and the first cellular antenna 52 can share a radiator to simplify the antenna system of the foldable electronic device 100 and reduce production costs. The first satellite communication antenna 2 and the first cellular antenna 52 can also be arranged separately, which are not limited in the present application. Similarly, the second satellite communication antenna 3 and the second cellular antenna 53 can also share a radiator or be arranged separately, which are not limited in the present application.

[0145] As shown in FIG. 20a-21b, in addition to the first shell 11 and the second shell 12, the foldable electronic device 100 can also be provided with a third shell 13, and the number of the third shell 13 is not limited and can be one or more. As shown in FIG. 20a-20b, in an embodiment, the first shell 11 and the second shell 12 are adjacent to each other to shorten the connection line between the first radio frequency module 22 and the processor 62 and reduce the line loss. As shown in FIG. 21a-21b, in an embodiment, the third shell 13 can be located between the first shell 11 and the second shell 12 to separate the first shell 11 and the second shell 12, and at this time, the second shell 12 is farther away from the first shell 11, and after folding, the second satellite communication antenna 3 can be farther away from the user's head, which can further reduce the radiation of the device to the human body and help to improve the communication quality of the satellite communication antenna in the head-hand scenario.
