[0058] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0059] It should be noted that, in this article, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element. Optionally, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context in the specific embodiment.

[0060] It should be understood that, although the terms first, second, third, etc. may be used to describe various information in this article, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this article, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein can be interpreted as "at the time of..." or "when..." or "in response to determination". Furthermore, as used in this article, the singular forms "one", "one" and "the" are intended to also include plural forms, unless there is an opposite indication in the context. It should be further understood that the terms "comprising", "including" indicate that there are the described features, steps, operations, elements, components, projects, kinds, and / or groups, but do not exclude the existence, occurrence or addition of one or at least two other features, steps, operations, elements, components, projects, kinds, and / or groups. The terms "or", "and / or", "including at least one of the following" etc. used in this application can be interpreted as inclusive, or mean any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”, and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”. An exception to this definition will only occur when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.

[0061] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)", depending on the context.

[0062] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0063] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

The mobile terminal may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0067] Combine the following Figure 1 The following is a detailed introduction to the various components of the mobile terminal:

[0069] WiFi is a short-range wireless transmission technology. Mobile terminals can help users send and receive emails, browse web pages, and access streaming media through WiFi module 1020. It provides users with wireless broadband Internet access. Figure 1 The WiFi module 1020 is shown, but it is understandable that it is not an essential component of the mobile terminal and can be omitted as needed without changing the essence of the invention.

[0070] The audio output unit 1030 can convert the audio data received by the RF unit 1010 or the WiFi module 1020 or stored in the memory 1090 into an audio signal and output it as sound when the mobile terminal 1000 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, etc. Moreover, the audio output unit 1030 can also provide audio output related to a specific function performed by the mobile terminal 1000 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 1030 may include a speaker, a buzzer, etc.

[0071] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 1040 may include a graphics processor (GPU) 1041 and a microphone 1042, and the graphics processor 1041 processes the image data of a static picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The processed image frame can be displayed on the display unit 1060. The image frame processed by the graphics processor 1041 can be stored in the memory 1090 (or other storage medium) or sent via the radio frequency unit 1010 or the WiFi module 1020. The microphone 1042 can receive sound (audio data) via the microphone 1042 in the operation modes such as the telephone call mode, the recording mode, the voice recognition mode, etc., and can process such sound into audio data. The processed audio (voice) data can be converted into a format output that can be sent to a mobile communication base station via the radio frequency unit 1010 in the case of the telephone call mode. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the process of receiving and transmitting audio signals.

[0072] The mobile terminal 1000 also includes at least one sensor 1050, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 1000 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can also be configured on the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0073] The display unit 1060 is used to display information input by the user or information provided to the user. The display unit 1060 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0074] The user input unit 1070 can be used to receive input digital or character information, and generate key signal input related to user settings and function control of the mobile terminal. Optionally, the user input unit 1070 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 1071 or near the touch panel 1071 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 1100, and can receive and execute commands sent by the processor 1100. In addition, the touch panel 1071 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch panel 1071, the user input unit 1070 may further include other input devices 1072.

[0075] Optionally, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 1100 to determine the type of the touch event. Then, the processor 1100 provides a corresponding visual output on the display panel 1061 according to the type of the touch event. Figure 1 In the figure, the touch panel 1071 and the display panel 1061 are used as two independent components to implement the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to implement the input and output functions of the mobile terminal, which is not limited here.

[0077] The memory 1090 can be used to store software programs and various data. The memory 1090 can mainly include a program storage area and a data storage area. Optionally, the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory 1090 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0078] The processor 1100 is the control center of the mobile terminal. It uses various interfaces and lines to connect various parts of the entire mobile terminal. It executes various functions of the mobile terminal and processes data by running or executing software programs and / or modules stored in the memory 1090, and calling data stored in the memory 1090, so as to monitor the mobile terminal as a whole. The processor 1100 may include one or at least two processing units; preferably, the processor 1100 may integrate an application processor and a modem processor. Optionally, the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 1100.

[0079] The mobile terminal 1000 may also include a power supply 1110 (such as a battery) for supplying power to various components. Preferably, the power supply 1110 may be logically connected to the processor 1100 via a power management system, thereby implementing functions such as managing charging, discharging, and power consumption management through the power management system.

[0080] The mobile terminal 1000 may also include a Bluetooth module, etc. Figure 1 Structures not shown will not be described in detail here.

[0081] See also Figure 2 , Figure 2A communication network system architecture diagram is provided for an embodiment of the present application.

[0083] E-UTRAN 202 includes eNodeB 2021 and other eNodeBs 2022, etc. Optionally, eNodeB 2021 may be connected to other eNodeBs 2022 via a backhaul (eg, an X2 interface), and eNodeB 2021 is connected to EPC 203, and eNodeB 2021 may provide UE 201 with access to EPC 203.

HSS 2032 is used to provide some registers to manage functions such as home location register (not shown in the figure), and save some user-specific information such as service features and data rates. All user data can be sent through SGW2034. PGW2035 can provide IP address allocation and other functions for UE201. PCRF2036 is the policy and charging control policy decision point for service data flow and IP bearer resources. It selects and provides available policy and charging control decisions for the policy and charging execution function unit (not shown in the figure).

[0085] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) or other IP services.

[0086] Although the above introduction takes the LTE system as an example, those skilled in the art should know that the present application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G and future new network systems (such as 6G), etc., without limitation here.

[0087] Based on the above-mentioned mobile terminal hardware structure, various embodiments of the present application are proposed.

[0088] As described in the background technology, the signals of at least two antennas in the prior art interfere with each other when the smart terminal is in a folded state, which affects the performance of the antenna device and further affects the performance of the smart terminal. The reason for this problem is that the smart terminal in the prior art has two shells that can be folded with each other, and a part of the antenna in the antenna device is arranged in one of the shells, and another part is arranged in the other shell. When the smart terminal is in a folded state, the antennas on the two shells will at least partially overlap in the thickness direction of the smart terminal, which will cause the signals of the antennas in the overlapping parts to interfere with each other, affecting the performance of the antenna device and the performance of the smart terminal.

[0089] In another case, even if the antennas on the two shells do not overlap in the thickness direction of the smart terminal, interference will be caused to the signal reception of the two antennas. For example, the two antennas are closely spaced in the horizontal direction perpendicular to the thickness direction of the smart terminal, or the two antennas have the same operating frequency band.

[0090] In response to the above technical problems, an embodiment of the present application provides an antenna device and a smart terminal, the antenna device includes at least two antennas, the smart terminal includes at least two shells and a folding part, at least one of the antennas is arranged on the shell, and at least one of the antennas is arranged on the folding part. When the smart terminal is in an unfolded state, the antenna arranged on the shell receives and sends signals, and when the smart terminal is in a folded state, it switches to the antenna arranged on the folding part to receive and send signals, thereby avoiding mutual interference between the signals of the antennas arranged on the shell when the smart terminal is in the folded state, thereby improving the performance of the antenna device and the performance of the smart terminal.

[0091] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0093] When the smart terminal is in the unfolded state, the antenna 100 disposed on the housing 10 transmits and receives signals.

[0094] When the smart terminal is in the folded state, the antennas 100 disposed on at least two shells 10 may interfere with each other. At this time, the antennas 100 with mutual signal interference can be switched to the antenna 100 disposed on the folding portion 20 for signal transmission and reception.

[0095] Optionally, when the smart terminal is in the folded state, the at least two antennas 100 disposed on the at least two housings 10 are switched to the antenna 100 disposed on the folding portion 20 to transmit and receive signals.

[0096] refer to Figure 3 In some embodiments, the smart terminal may have two housings 10, three housings 10 or even at least two housings 10. When the smart terminal has two housings 10, the folding portion 20 may have one, and the two housings 10 are folded relative to the folding portion 20. At least one antenna 100 can be disposed on each of the two housings 10, and at least one antenna 100 can also be disposed on the folding portion 20.

[0097] When the smart terminal is in the unfolded state, the antennas 100 on the two housings 10 transmit and receive signals, and the antenna 100 on the folding portion 20 may not transmit and receive signals.

[0098] When the smart terminal is in a folded state, the two shells 10 are folded against each other, and the antenna 100 on one shell 10 can at least partially overlap with the antenna 100 on the other shell 10, for example, the two antennas 100 completely overlap or partially overlap, resulting in mutual interference between the signal reception and transmission of the antennas 100 on the two shells 10. At this time, the antennas 100 on the two shells 10 can switch to the antenna 100 on the folding portion 20 for signal reception and transmission.

[0099] In other embodiments, the smart terminal may also have three housings 10 and at least two folding portions 20. If there is one folding portion 20, two of the three housings 10 can be folded together, wherein at least the two housings 10 folded together can be provided with antennas 100, and the folding portion 20 can also be provided with antennas 100. When the smart terminal is in a folded state, the two housings 10 provided with antennas 100 are folded together, and the antenna 100 on one housing 10 can at least partially overlap with the antenna 100 on the other housing 10, and at this time, the antennas 100 on the two housings 10 can switch to the antenna 100 on the folding portion 20 for signal transmission and reception.

[0100] If there are two folding portions 20, the three housings 10 can all be folded relative to the folding portions 20. At least one antenna 100 can be provided on each housing 10, and the two folding portions 20 can also be provided with antennas 100. When the smart terminal is in a folded state, the antennas 100 on any two housings 10 can at least partially overlap in the thickness direction of the smart terminal. At this time, the antennas 100 on the housings 10 that at least partially overlap in the thickness direction of the smart terminal can switch to the antenna 100 on the folding portion 20 to send and receive signals.

[0101] In some embodiments, when the smart terminal is in a folded state, the signals of at least two antennas 100 that are arranged on at least two shells 10 and at least partially overlap in the thickness direction of the smart terminal may be antennas 100 of the same frequency band, or the operating frequency bands of at least two antennas 100 that at least partially overlap in the thickness direction of the smart terminal are at least partially the same.

[0102] The embodiment of the present application provides an antenna 100 device and a smart terminal. The antenna 100 device includes at least two antennas 100. The smart terminal includes at least two shells 10 and a folding portion 20. At least one of the at least two antennas 100 is arranged on one of the at least two shells 10, at least one of the at least two antennas 100 is arranged on the other of the at least two shells 10, and at least one of the at least two antennas 100 is arranged on the folding portion 20. When the smart terminal is in an unfolded state, the antenna 100 arranged on the shell 10 receives and sends signals. When the smart terminal is in a folded state, the at least two antennas 100 arranged on the at least two shells 10 switch to the antenna 100 arranged on the folding portion 20 for receiving and sending signals, thereby avoiding mutual interference of signals between the at least two antennas 100 arranged on the at least two shells 10 when the smart terminal is in a folded state, thereby improving the performance of the antenna 100 device and the performance of the smart terminal.

[0103] refer to Figure 5 In some embodiments, the antenna 100 device may further include at least two switches 200, and each housing 10 provided with the antenna 100 is provided with a part of the at least two switches 200, and the switch 200 is used to control the signal switching between the antenna 100 provided on the folding portion 20 and the antenna 100 on the housing 10. At least two antennas 100 provided on at least two housings 10 and at least partially overlapping in the thickness direction of the smart terminal are switched to the antenna 100 provided on the folding portion 20 for signal transmission and reception.

[0104] Optionally, the antenna 100 device includes a switch 200 so that the antenna 100 on the shell 10 can be switched to the antenna 100 on the folding portion 20 through the switch 200 to receive and send signals, thereby facilitating the switching of signals between the antenna 100 on the shell 10 and the antenna 100 on the folding portion 20, thereby improving the ease of use of the antenna 100 device.

[0105] refer to Figure 5 If at least two shells 10 have two, one of which has an antenna 100, and the other shell 10 also has an antenna 100, when the smart terminal is in a folded state, the two antennas 100 at least partially overlap, then one of the shells 10 can be provided with a switch 200, and the transmission and reception of signals can be switched between the antenna 100 on the shell 10 and the antenna 100 on the folding portion 20.

[0106] Optionally, a switch 200 may also be provided on the other housing 10 , and the transmission and reception of signals may also be switched between the antenna 100 on the housing 10 and the antenna 100 on the folding portion 20 .

[0107] In other embodiments, if at least two housings 10 have two antennas 100, one of the housings 10 has two antennas 100, and the other housing 10 also has two antennas 100. When the smart terminal is in a folded state, the two antennas 100 on one housing 10 at least partially overlap with the two antennas 100 on the other housing 10, and two switches 200 may be provided on both housings 10, wherein the two switches 200 on one housing 10 are respectively controlled and connected with the two antennas 100 on the housing 10 and the antenna 100 on the folding portion 20, and the signals of the two antennas 100 on the housing 10 can be switched to the antenna 100 on the folding portion 20 for transmission and reception through the corresponding switches 200.

[0108] Optionally, the two switches 200 on the other shell 10 are also controlled and connected to the two antennas 100 on the shell 10 and the antenna 100 on the folding part 20 respectively, and the signals of the two antennas 100 on the shell 10 can be switched to the antenna 100 on the folding part 20 for transmission and reception through the corresponding switches 200.

[0109] refer to Figure 5 In an exemplary embodiment, the at least two antennas 100 may include a first antenna 110, a second antenna 120 and a third antenna 130, and the first antenna 110 at least has the same operating frequency band as the second antenna 120. The at least two switches 200 may include a first switch 210 and a second switch 220.

[0110] Optionally, the shell 10 may include a first shell 10a and a second shell 10b, the first antenna 110 is arranged on the folding portion 20, the second antenna 120 is arranged on the first shell 10a, and the third antenna 130 is arranged on the second shell 10b. When the smart terminal is in a folded state, the second antenna 120 and the third antenna 130 at least partially overlap in the thickness direction of the smart terminal.

[0111] Optionally, the first switch 210 can control the signal to switch between the first antenna 110 and the second antenna 120 , and the second switch 220 can control the signal to switch between the first antenna 110 and the third antenna 130 .

[0112] Optionally, if the smart terminal is in the unfolded state, the first antenna 110 arranged on the folding portion 20 may not send or receive signals, but only transmit signals through the second antenna 120 arranged on the first shell 10 and the third antenna 130 arranged on the second shell 10. At this time, the signals of the second antenna 120 and the third antenna 130 will not interfere with each other.

[0113] Optionally, if the smart terminal is in the folded state, the transmission and reception of the signal of the second antenna 120 can be switched to the first antenna 110 through the first switch 210, and the transmission and reception of the signal of the third antenna 130 can also be switched to the first antenna 110 through the second switch 220. Thus, mutual interference between the signals of the second antenna 120 and the third antenna 130 can be avoided.

[0114] In one possible implementation, the second antenna 120 and the third antenna 130 may be antennas 100 of the same frequency band. When the smart terminal is in a folded state, since the second antenna 120 and the third antenna 130 at least partially overlap in the thickness direction of the smart terminal, the signal interference between the second antenna 120 and the third antenna 130 will be strong. In this case, it is necessary to switch the signal on the second antenna 120 to the first antenna 110 for transmission and reception through the first switch 210, or switch the signal on the third antenna 130 to the first antenna 110 for transmission and reception. Alternatively, while the signal on the second antenna 120 is switched to the first antenna 110 for transmission and reception, the signal on the third antenna 130 can also be switched to the first antenna 110 for transmission and reception.

[0115] refer to Figure 5 In some embodiments, the first antenna 110 may include at least one first radiator 111, which is disposed on the folding portion 20, the second antenna 120 may include a second radiator 121, which is disposed on the first shell 10a, and the third antenna 130 may include a third radiator 131, which is disposed on the second shell 10b. When the smart terminal is in a folded state, the second radiator 121 and the third radiator 131 at least partially overlap in the thickness direction of the smart terminal.

[0116] In some embodiments, the folding portion 20 may have a metal part, which may serve as the first radiator 111 of the first antenna 110. The first shell 10a and the second shell 10b may both have a metal frame 11, and the second antenna 120 may use a part of the metal frame 11 on the first shell 10a as the second radiator 121, and the third antenna 130 may use a part of the metal frame 11 on the second shell 10b as the third radiator 131.

[0117] When the smart terminal is in the folded state, the second radiator 121 and the third radiator 131 can partially overlap in the thickness direction of the smart terminal, so that the second antenna 120 and the third antenna 130 can partially overlap in the thickness direction of the smart terminal.

[0118] refer to Figure 5In some embodiments, the first antenna 110 may also include at least one feeding point 112 and at least one grounding point 113 arranged on the folding portion 20, the feeding point 112 is electrically connected to the first radiator 111, the feeding point 112 is used to transmit a signal to the first radiator 111, the grounding point 113 is electrically connected to the first radiator 111, and the first radiator 111 is grounded through the grounding point 113.

[0119] In some embodiments, the second antenna 120 may also have a feeding point and a grounding point, and the first housing 10a where the second antenna 120 is located may also have a circuit board, which is electrically connected to the feeding point of the second antenna 120. The feeding point of the first antenna 110 may also be electrically connected to the circuit board.

[0120] Optionally, the third antenna 130 may also have a feeding point and a grounding point, and the second housing 10b where the third antenna 130 is located may also have a circuit board, which is electrically connected to the feeding point of the third antenna 130. The feeding point 112 of the first antenna 110 may also be electrically connected to the circuit board.

[0121] In other embodiments, the folding portion 20 of the smart terminal may also have a circuit board, and the feeding point 112 and the grounding point 113 of the first antenna 110 can be electrically connected to the circuit board on the folding portion 20. Compared with electrically connecting the feeding point 112 of the first antenna 110 to the circuit board arranged on the shell 10, the connection distance between the circuit board and the feeding point 112 can be shortened, and the transmission distance between the circuit board and the feeding point 112 can be shortened, which can simplify the internal structure of the smart terminal.

[0122] refer to Figure 5 In some embodiments, the antenna 100 device may further include a control mechanism 300, the control mechanism 300 is electrically connected to the switch 200, and the control mechanism 300 controls the switch 200 to switch between the antenna 100 on the housing 10 and the antenna 100 on the folding portion 20 with a control signal. The control mechanism 300 can control the switch 200 to be turned on or off according to the unfolded or folded state of the smart terminal.

[0123] When the smart terminal is in the unfolded state, the control mechanism 300 can control the switch 200 to be connected to the antenna 100 on the shell 10, and disconnect the switch 200 from the antenna 100 on the folding part 20 to prevent the antenna 100 on the shell 10 from switching to the antenna 100 on the folding part 20 for sending and receiving signals.

[0124] When the smart terminal is in a folded state, the control mechanism 300 can control the switch 200 to disconnect from the antenna 100 on the shell 10, and connect the switch 200 to the antenna 100 on the folding portion 20, so that the antenna 100 on the shell 10 can switch to the antenna 100 on the folding portion 20 for sending and receiving signals.

[0125] On the basis of the above embodiment, if the antenna 100 device includes a first antenna 110, a second antenna 120 and a third antenna 130, the first antenna 110 is arranged on the folding portion 20, the second antenna 120 is arranged on the first shell 10a, the third antenna 130 is arranged on the second shell 10b, and at least two switches 200 include a first switch 210 and a second switch 220.

[0126] Optionally, the first switch 210 may be selectively connected to the first antenna 110 or the second antenna 120 to control the signal to be switched between the first antenna 110 and the second antenna 120 .

[0127] Optionally, the first switch 210 may be selectively connected to the first antenna 110 or the third antenna 130 to control the signal to switch between the first antenna 110 and the third antenna 130 .

[0128] In some embodiments, the first switch 210 and the second switch 220 may both be single-pole double-throw switches.

[0129] If the smart terminal is in the unfolded state, the control mechanism 300 can control the first switch 210 to be connected to the second antenna 120, and disconnect the first switch 210 from the first antenna 110 to prevent the signal from being switched from the second antenna 120 to the first antenna 110 for transceiving. The control mechanism 300 can also control the second switch 220 to be connected to the third antenna 130, and disconnect the second switch 220 from the first antenna 110 to prevent the signal from being switched from the third antenna 130 to the first antenna 110 for transceiving.

[0130] If the smart terminal is in the folded state, the control mechanism 300 can control the first switch 210 to disconnect from the second antenna 120, and connect the first switch 210 to the first antenna 110, so that the signal is switched from the second antenna 120 to the first antenna 110 for transceiving. The control mechanism 300 can also control the second switch 220 to disconnect from the third antenna 130, and connect the second switch 220 to the first antenna 110, so that the signal is also switched from the third antenna 130 to the first antenna 110 for transceiving.

[0131] In other embodiments, the control mechanism 300 can also determine the signal strength when the antenna 100 on the housing 10 is switched to the antenna 100 on the folding portion 20, and switch the signal with the weaker signal strength among the at least two signals switched to the folding portion 20 back to the antenna 100 on the housing 10 corresponding thereto. By setting the control mechanism 300, the use flexibility of the antenna 100 device can be improved, thereby enriching the functions of the antenna 100 device and the use flexibility of the smart terminal.

[0132] If the smart terminal is in the folded state, the control mechanism 300 can control the first switch 210 to disconnect from the second antenna 120, and connect the first switch 210 to the first antenna 110, so that the second antenna 120 switches to the first antenna 110 for signal transmission and reception. At this time, the control mechanism 300 can determine the signal strength in the working frequency band where the second antenna 120 and the third antenna 130 switched to the first antenna 110 are located. If the signal in the working frequency band where the second antenna 120 is located is weak, the control mechanism 300 can control the first switch 210 to switch the signal back to the second antenna 120. Similarly, if the signal in the working frequency band where the third antenna 130 is located is weak, the control mechanism 300 can control the second switch 220 to switch the signal back to the third antenna 130.

[0133] refer to Figure 6 The embodiment of the present application also provides a smart terminal, which may include at least two shells 10 and a folding portion 20, and the antenna 100 device as above.

[0134] Optionally, the folding portion 20 may include a rotating mechanism 30, and two of the at least two housings 10 are connected and folded by rotating the rotating mechanism 30. The antenna 100 device may include at least two antennas 100, at least one of the at least two antennas 100 is disposed on one of the at least two housings 10, at least one of the at least two antennas 100 is disposed on the other of the at least two housings 10, and at least one of the at least two antennas 100 is disposed on the rotating mechanism 30.

[0135] When the smart terminal is in the folded state, signals on at least two antennas 100 disposed on at least two housings 10 and at least partially overlapping in the thickness direction of the smart terminal are switched to the antenna 100 disposed on the rotating mechanism 30 for signal transmission and reception.

[0136] refer to Figure 6In some embodiments, each housing 10 may have a metal frame 11. When the smart terminal is folded, the metal frames 11 of each housing 10 overlap in the thickness direction of the smart terminal. The antenna 100 disposed on the housing 10 can use a portion of the metal frame 11 as a radiator to radiate signals. When the smart terminal is in the folded state, the radiator of the antenna 100 on the metal frame 11 can at least partially overlap in the thickness direction of the smart terminal.

[0137] refer to Figure 6 In some embodiments, the smart terminal may have two housings 10, three housings 10, or at least two housings 10. When the smart terminal has two housings 10, the rotating mechanism 30 may have one, and the two housings 10 are folded relative to the rotating mechanism 30 of the folding portion 20. At least one antenna 100 can be provided on each of the two housings 10, and at least one antenna 100 can also be provided on the rotating mechanism 30.

[0138] When the smart terminal is in the unfolded state, the antennas 100 on the two housings 10 transmit and receive signals, and the antenna 100 on the rotating mechanism 30 may not transmit and receive signals.

[0139] When the smart terminal is in a folded state, the two shells 10 are folded against each other, and the antenna 100 on one shell 10 can at least partially overlap with the antenna 100 on the other shell 10, for example, the two antennas 100 completely overlap or partially overlap. At this time, the antennas 100 on the two shells 10 can switch to the antenna 100 on the rotating mechanism 30 to send and receive signals.

[0140] In other embodiments, the smart terminal may have three housings 10 and at least two rotating mechanisms 30. If there is one rotating mechanism 30, two of the three housings 10 can be folded together, wherein at least the two housings 10 folded together can be provided with antennas 100, and the rotating mechanism 30 can also be provided with antennas 100. When the smart terminal is in a folded state, the two housings 10 provided with antennas 100 are folded together, and the antenna 100 on one housing 10 can at least partially overlap with the antenna 100 on the other housing 10, and at this time, the antennas 100 on the two housings 10 can switch to the antenna 100 on the rotating mechanism 30 for signal transmission and reception.

[0141] If there are two rotating mechanisms 30, the three housings 10 can be bent and folded relative to the rotating mechanisms 30. Each antenna 100 device can be provided with at least one antenna 100, and the two rotating mechanisms 30 can also be provided with antennas 100. When the smart terminal is in a folded state, the antennas 100 on any two housings 10 can at least partially overlap in the thickness direction of the smart terminal. At this time, the antennas 100 on the housings 10 that at least partially overlap in the thickness direction of the smart terminal can be switched to the antennas 100 on the rotating mechanism 30 for signal transmission and reception.

[0142] refer to Figure 6 In a possible implementation, the number of at least two shells 10 is two, the two shells 10 are connected by a rotating mechanism 30, and some of the at least two antennas 100 are respectively arranged on the two shells 10. When the smart terminal is in a folded state, the antennas 100 respectively arranged on the two shells 10 at least partially overlap in the thickness direction of the smart terminal.

[0143] Optionally, one of the shells 10 may be provided with one antenna 100, two antennas 100 or even at least two antennas 100 among the partial antennas 100, and the other shell 10 may also be provided with one antenna 100, two antennas 100 or even at least two antennas 100 among the partial antennas 100.

[0144] The number of antennas 100 on the two shells 10 is not necessarily the same, but at least one antenna 100 on one shell 10 at least partially overlaps with at least one antenna 100 on the other shell 10 in the thickness direction of the smart terminal.

[0145] refer to Figure 6 and Figure 7 In some embodiments, the rotating mechanism 30 may include a protective cover 32 and a rotating structure 31. The two housings 10 are rotatably connected through the rotating structure 31. The protective cover 32 is disposed on the outside of the rotating structure 31. The two housings 10 can be rotatably connected through the rotating structure 31, and the two housings 10 can be folded and unfolded relative to the rotating structure 31. By arranging the protective cover 32 on the outside of the rotating structure 31, the rotating structure 31 can be protected, and the damage to the rotating structure 31 caused by external impact or collision can be reduced. In addition, by arranging the protective cover 32, the probability of debris in the external environment entering the rotating structure 31 can be reduced, and the influence of external debris on the rotating structure 31 can be reduced.

[0146] refer to Figure 6In some embodiments, the antenna 100 disposed on the rotating mechanism 30 is a first antenna 110, and the first antenna 110 may include at least one first radiator 111, and the first radiator 111 is disposed on the side of the protective cover 32 facing the rotating structure 31. By disposing the first radiator 111 of the first antenna 110 on the protective cover 32, it is possible to switch the antenna 100 on the housing 10 to the first radiator 111 on the protective cover 32 for signal transmission and reception when the smart terminal is in a folded state.

[0147] In some embodiments, the first radiator 111 of the first antenna 110 may be a patch structure and formed on the protective cover 32 , or the first radiator 111 may be formed by a laser direct structuring (LDS) process and disposed on the protective cover 32 .

[0148] In other embodiments, the protective cover 32 may also be a metal cover, and the first antenna 110 uses the metal cover as the first radiator 111. By setting the protective cover 32 as a metal cover, the first antenna 110 can directly use the metal cover as the first radiator 111, thereby simplifying the preparation process of the first radiator 111, and allowing the metal cover to be used not only as the protective cover 32, but also as the first radiator 111 of the first antenna 110, so that the metal cover has multiple functions, reducing the manufacturing cost and reducing the space occupancy rate of the first antenna 110.

[0149] refer to Figure 6 In some embodiments, the first antenna 110 may further include a feeding point 112 and a grounding point 113; the smart terminal also includes a circuit board 40, the feeding point 112 and the grounding point 113 are arranged on the circuit board 40, the first radiator 111 is electrically connected to the feeding point 112, and is grounded through the grounding point 113, and the circuit board 40 is arranged on the rotating structure 31.

[0150] The first antenna 110 includes a feeding point 112 and a grounding point 113, and the smart terminal includes a circuit board 40. The circuit board 40 is set on the rotating structure 31, and the feeding point 112 and the grounding point 113 are both set on the circuit board 40, thereby shortening the transmission distance of the first antenna 110 for feeding and grounding, improving the transmission efficiency, further simplifying the internal structure of the smart terminal, and improving the internal space utilization of the smart terminal.

[0151] In some embodiments, the circuit board 40 may be connected to the rotating structure 31, or be disposed near the rotating structure 31, for example, disposed on the side of the protective cover 32 facing the rotating structure 31. When the smart terminal is folded or opened, the rotating structure 31 may rotate relative to the rotating structure 31, and the circuit board 40 does not rotate with the rotation of the rotating structure 31, thereby avoiding the reduction of the connection stability between the feeding point 112 and the grounding point 113 and the first antenna 110 due to the frequent movement of the circuit board 40.

[0152] refer to Figure 6 and Figure 7 In a possible implementation, there is a receiving cavity 33 between the rotating structure 31 and the protective cover 32, and the circuit board 40 is disposed in the receiving cavity 33, and the circuit board 40 is connected to the rotating structure 31. It is understandable that a gap 34 is required between the protective cover 32 and the rotating structure 31 to avoid frequent friction between the protective cover 32 and the rotating structure 31, which may cause wear of the rotating structure 31 or the protective cover 32, and to avoid the friction resistance between the rotating structure 31 and the protective cover 32 affecting the user experience during the folding and opening of the smart terminal.

[0153] The circuit board 40 is arranged in the accommodating cavity 33 between the rotating structure 31 and the protective cover 32, and is relatively fixed by being connected to the circuit board 40, so that the space of the accommodating cavity 33 can be fully utilized, and the distance from the first antenna 110 to the feeding point 112 and the grounding point 113 is shortened, thereby improving the internal space utilization rate of the smart terminal.

[0154] refer to Figure 6 In some other embodiments, in another possible implementation, there are at least two rotating structures 31 , there is a gap 34 between every two adjacent rotating structures 31 , and the circuit board 40 is disposed in the gap 34 between the two adjacent rotating structures 31 .

[0155] By disposing the circuit board 40 in the gap 34 between two adjacent rotating structures 31 , the influence of the circuit board 40 on the rotating process of the rotating structure 31 can be reduced, and wear between the circuit board 40 and the protective cover 32 can be avoided.

[0156] Furthermore, by setting the circuit board 40 in the interval 34 between the two rotating structures 31, the interval 34 between the two adjacent rotating structures 31 can be fully utilized to avoid occupying the accommodating cavity 33 between the rotating structure 31 and the protective cover 32, thereby further improving the internal space utilization of the smart terminal.

[0157] In some embodiments, the rotating structure 31 can be a rotating shaft. If the smart terminal has two housings 10, the two housings 10 can be rotatably connected via the rotating shaft. If there are at least two rotating shafts, the at least two rotating shafts can be arranged at intervals 34 in the axial direction of the rotating shafts, and the circuit board 40 can be disposed in the interval 34 between any two connected rotating shafts.

[0158] refer to Figure 6 In some embodiments, the smart terminal may further include a detection device 50, which is disposed in at least one of the two housings 10, and is used to detect the folding and unfolding states of the smart terminal.

[0159] By setting up a detection device 50 in the smart terminal, the folding and unfolding state of the smart terminal can be detected by the detection device 50, and the state of the smart terminal can be fed back to the control mechanism 300.
