[0003] However, foldable electronic devices are inconvenient to operate when adjusting call notification modes. Summary of the Invention

[0004] This application provides a foldable electronic device to solve the technical problem of inconvenient operation when adjusting the caller ID mode of a foldable electronic device.

[0005] This application provides a foldable electronic device, including:

[0006] The shell assembly includes a first shell and a second shell that are movably connected;

[0007] A folding mechanism is connected between the first housing and the second housing, enabling the first housing and the second housing to fold and rotate relative to each other;

[0008] The detection module is used to detect the relative angle between the first housing and the second housing;

[0009] Incoming call alert module, used to alert callers, the incoming call alert module having a first response mode and a second response mode; and

[0010] The control module is electrically connected to the detection module and the incoming call reminder module. When the detection module detects that the first housing and the second housing are folded together, the control module controls the incoming call reminder module to switch from the first response mode to the second response mode.

[0011] In one embodiment, the incoming call alert module includes a vibrator and a speaker, the vibrator being used to respond to the first response mode and the speaker being used to respond to the second response mode.

[0012] In one embodiment, when the detection module detects that the first housing and the second housing are unfolded, the control module controls the incoming call reminder module to switch from the second response mode to the first response mode.

[0013] In one embodiment, the detection module includes at least one of a capacitive sensor, a pressure sensor, an optical sensor, or an ultrasonic sensor.

[0014] In one embodiment, the detection module includes a Hall sensor and a magnetic component. One of the Hall sensor and the magnetic component is disposed in the folding mechanism, and the other is disposed in the first housing or the second housing. When the first housing and the second housing rotate relative to each other, the Hall sensor and the magnetic component move relative to each other. The Hall sensor is used to obtain the relative rotation angle between the first housing and the second housing by detecting changes in the magnetic field.

[0015] In one embodiment, the folding mechanism includes a pivot, and the detection module is used to obtain the relative angle between the first housing and the second housing by detecting the rotation angle of the pivot.

[0016] In one embodiment, the folding mechanism includes a pivot and a first gear connected to the pivot. At least one of the first housing and the second housing is provided with a second gear. When the first housing and the second housing rotate relative to each other, the pivot drives the second gear to rotate via the first gear. The detection module is used to obtain the relative rotation angle between the first housing and the second housing by detecting the rotation angle of the second gear.

[0017] In one embodiment, the first gear and the second gear mesh with each other, and the transmission ratio between the first gear and the second gear is 1:3 to 1:2;

[0018] Alternatively, the first gear and the second gear can be linked together via a conveyor belt.

[0019] In one embodiment, the folding mechanism includes a rotating shaft and a gear connected to the rotating shaft. At least one of the first housing and the second housing is provided with a rack, which is slidably connected to the housing assembly and drivenly connected to the gear. The detection module obtains the relative rotation angle between the first housing and the second housing by detecting the displacement change of the rack.

[0020] In one embodiment, a flexible screen is included, which is connected to the first housing and the second housing, and the flexible screen can be retracted into or extended from the housing assembly as the first housing and the second housing rotate.

[0021] In this embodiment, since the incoming call reminder module is electrically connected to the detection module, and the incoming call reminder module switches from the first response mode to the second response mode when the detection module detects that the first housing and the second housing have unfolded together, the switching operation of the incoming call information prompt mode is simplified and the user experience is improved.

Detailed Implementation

[0033] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0034] As used herein, "foldable electronic device" refers to, but is not limited to, a device capable of receiving and / or transmitting communication signals connected via any one or more of the following connection methods:

[0035] (1) Via wired connection, such as via Public Switched Telephone Networks (PSTN), Digital Subscriber Line (DSL), digital cable, or direct cable connection;

[0036] (2) Via wireless interface, such as cellular network, wireless local area network (WLAN), digital television network such as DVB-H network, satellite network, AM-FM broadcast transmitter.

[0037] A foldable electronic device configured to communicate via a wireless interface can be referred to as a "mobile terminal". Examples of mobile terminals include, but are not limited to, the following foldable electronic devices:

[0038] (1) Satellite phone or cellular phone;

[0039] (2) A Personal Communications System (PCS) terminal that can combine cellular radio telephone with data processing, fax and data communication capabilities;

[0040] (3) Radio telephone, pager, Internet / intranet access, web browser, notepad, calendar, personal digital assistant (PDA) equipped with a Global Positioning System (GPS) receiver;

[0041] (4) Conventional above-knee and / or palm-sized receivers;

[0042] (5) Conventional knee-mounted and / or handheld wireless telephone transceivers, etc.

[0043] See Figure 1 and Figure 2As shown, this application provides a foldable electronic device 100, including a shell assembly 10 and a folding mechanism 20. The shell assembly 10 includes a first shell 12 and a second shell 14 movably connected. The second shell 14 and the first shell 12 are capable of relative movement about a folding axis Z. In this embodiment, the folding mechanism 20 is connected between the first shell 12 and the second shell 14, enabling the second shell 14 and the first shell 12 to fold around the folding axis Z. It is understood that the foldable electronic device 100 of this application includes, but is not limited to, foldable mobile phones, foldable computers, and other terminal devices.

[0044] The folding mechanism 20 can be a hinge structure or a support structure with a pivot 20a. The structure of the folding mechanism 20 is not limited here, as long as it can meet the folding and flattening requirements of the foldable electronic device 100.

[0045] Continue to combine Figure 1 and Figure 2 As shown, the foldable electronic device 100 includes a detection module 30, a call reminder module 40, and a control module 50. The detection module 30 detects the relative angle α between the first housing 12 and the second housing 14. The call reminder module 40 is used to indicate incoming calls and has a first response mode and a second response mode. Both the detection module 30 and the call reminder module 40 are electrically connected to the control module 50. When the detection module 30 detects that the first housing 12 and the second housing 14 are folded together, the control module 50 controls the call reminder module 40 to switch from the first response mode to the second response mode. In this embodiment, because the call reminder module 40 is electrically connected to the detection module 30, and the control module 50 controls the call reminder module 40 to switch from the first response mode to the second response mode when the detection module 30 detects that the first housing 12 and the second housing 14 are unfolded, the switching operation of the call information prompt mode is simplified, improving the user experience.

[0046] For ease of explanation, the two extreme positions of relative rotation between the first housing 12 and the second housing 14 are referred to as the "unfolded position" and the "folded position," respectively. That is, the second housing 14 can move relative to the first housing 12 around the folding axis Z to both the flattened position and the folded position. In the flattened position, the relative rotation angle α between the first housing 12 and the second housing 14 is 180°, and in the folded position, the relative rotation angle α between the first housing 12 and the second housing 14 is 0°. It is understood that in the embodiments described below, the terms "flattened position," "folded position," and similar expressions all refer to the relative position of the second housing 14 and the first housing 12. For simplicity, expressions such as "the second housing 14 is in the flattened position" or "in the flattened position" mean that the second housing 14 is in the flattened position relative to the first housing 12, and expressions such as "the second housing 14 is in the folded position" or "in the folded position" mean that the second housing 14 is in the folded position relative to the first housing 12.

[0047] The incoming call alert module 40 includes a vibrator 40a and a speaker 40b. The vibrator 40a is used to respond to a first response mode, and the speaker 40b is used to respond to a second response mode. When the detection module 30 detects that the first housing 12 and the second housing 14 are unfolded relative to each other, the control module 50 controls the vibration mode (i.e., the first response mode) of the vibrator 40a of the incoming call alert module 40 to switch to the ringing mode (i.e., the second response mode) of the speaker 40b. Therefore, it avoids the user not being able to easily receive incoming call alert information when the phone is placed in their pocket.

[0048] In some embodiments, when the detection module 30 detects that the first housing 12 and the second housing 14 are unfolded relative to each other, the control module 50 controls the incoming call reminder module 40 to switch from the second response mode to the first response mode. Thus, by operating the folded or unfolded state of the foldable electronic device 100, the incoming call reminder mode can be switched.

[0049] Taking the first response mode as vibration mode and the second response mode as ringing mode as an example, when the foldable electronic device 100 is folded, the incoming call reminder module 40 switches from the first response mode to the second response mode, and the foldable electronic device 100 enters the ringing mode; when the foldable electronic device 100 is unfolded, the incoming call reminder module 40 switches from the second response mode to the first response mode, and the foldable electronic device 100 enters the vibration mode.

[0050] In some embodiments, the detection module 30 may employ Hall effect detection technology to detect the relative rotation angle α between the first housing 12 and the second housing 14. For example, combined with... Figure 3As shown, the detection module 30 includes a Hall sensor 30a and a magnetic element 30b. One of the Hall sensor 30a and the magnetic element 30b is disposed on the folding mechanism 20, and the other is disposed on the first housing 12 or the second housing 14. When the first housing 12 and the second housing 14 rotate relative to each other, the Hall sensor 30a and the magnetic element 30b move relative to each other. The Hall sensor 30a is used to obtain the relative rotation angle α between the first housing 12 and the second housing 14 by detecting changes in the magnetic field. In this embodiment, the Hall sensor 30a can be a single-axis Hall element or a multi-axis Hall element. The magnetic element 30b can be a magnet or a magnetic steel, without limitation, as long as the Hall sensor 30a can detect the change in the magnetic field caused by the movement of the magnetic element 30b to meet the requirement of detecting the relative rotation angle α between the first housing 12 and the second housing 14. The magnetic element 30b can have its N pole facing the side where the Hall element is located, or its S pole facing the side where the Hall element is located.

[0051] It should be noted that the detection module 30 can detect the relative rotation angle α between the first housing 12 and the second housing 14 directly or indirectly.

[0052] For example, combining Figure 4 As shown, the folding mechanism 20 includes a rotating shaft 20a. The detection module 30 is used to obtain the relative rotation angle α between the first housing 12 and the second housing 14 by detecting the rotation angle of the rotating shaft 20a. It should be noted that the rotation angle of the rotating shaft 20a is relative to the first housing 12 or relative to the second housing 14. In other words, the rotation angle of the rotating shaft 20a corresponds to the angle of rotation of the first housing 12 around the rotating shaft 20a, or the rotation angle of the rotating shaft 20a corresponds to the angle of rotation of the second housing 14 around the rotating shaft 20a.

[0053] For example, combining Figure 5 As shown, the folding mechanism 20 includes a rotating shaft 20a and a first gear 20b connected to the rotating shaft 20a. At least one of the first housing 12 and the second housing 14 is provided with a second gear 10a. When the first housing 12 and the second housing 14 rotate relative to each other, the rotating shaft 20a drives the second gear 10a to rotate via the first gear 20b. The detection module 30 is used to obtain the relative rotation angle α between the first housing 12 and the second housing 14 by detecting the rotation angle of the second gear 10a.

[0054] The first gear 20b and the second gear 10a mesh with each other, and the transmission ratio between the first gear 20b and the second gear 10a is 1:3 to 1:2. This allows the second gear 10a to achieve a larger rotation angle than the first gear 20b, thus improving the detection accuracy of the detection module 30. Specifically, during the relative rotation of the first housing 12 and the second housing 14, the maximum rotation angle between them is from the folded position to the unfolded position. During this process, the first housing 12 relative to the axis 20a and the second housing 14 relative to the axis 20a may rotate only slightly, which is not conducive to accurate detection by the detection module 30. By setting the transmission ratio between the first gear 20b and the second gear 10a to 1:3 to 1:2, the aforementioned small-amplitude rotation can be effectively converted into a large-amplitude rotation of the second gear 10a. This allows the detection module 30 to accurately detect the rotation angle of the second gear 10a, and then calculate the relative rotation angle α between the first housing 12 and the second housing 14 using the transmission ratio between the second gear 10a and the first gear 20b (i.e., the rotating shaft 20a).

[0055] For example, in some implementations, combined with Figure 6 As shown, the folding mechanism 20 includes a rotating shaft 20a and a gear (e.g., a first gear 20b). The gear is connected to the rotating shaft 20a. At least one of the first housing 12 and the second housing 14 is provided with a rack 10b. The rack 10b is slidably connected to the housing assembly 10 and is driven by the gear. That is, when the gear rotates with the rotating shaft 20a, it can drive the rack 10b to slide relative to the housing assembly 10. The detection module 30 obtains the relative rotation angle α between the first housing 12 and the second housing 14 by detecting the displacement change of the rack 10b.

[0056] In some embodiments, the first gear 20b and the second gear 10a can also be linked by a conveyor belt. Thus, the rotation angle of the first gear 20b can be calculated from the rotation angle of the second gear 10a. Since the first gear 20b is caused by the relative rotation of the first housing 12 and the second housing 14, the relative rotation angle α between the first housing 12 and the second housing 14 can be calculated from the rotation angle of the first gear 20b.

[0057] The type of detection module 30 is not limited here. In some embodiments, the detection module 30 may also be at least one of a capacitive sensor, a pressure sensor, an optical sensor, or an ultrasonic sensor.

[0058] In some embodiments, the foldable electronic device 100 may be a display-enabled device, for example, combined with Figure 7 and Figure 8As shown, the foldable electronic device 100 includes a flexible screen 60 connected to the housing assembly 10. Specifically, the flexible screen 60 is connected to the first housing 12 and the second housing 14, and the flexible screen 60 can be retracted into or extended from the housing assembly 10 as the first housing 12 and the second housing 14 rotate.

[0059] As the first housing 12 and the second housing 14 move relative to each other around the folding axis Z, the flexible screen 60 bends around the folding axis Z. Finally, when the second housing 14 moves to the folded position, the flexible screen 60 is folded between the first housing 12 and the second housing 14 and is not exposed. Thus, the foldable electronic device 100 is not only convenient to carry, but also provides good protection for the flexible screen 60 when the foldable electronic device 100 is dropped.

[0060] When the second housing 14 is in the flat position, the foldable electronic device 100 can obtain a relatively large display area, thereby obtaining a large-screen display visual experience and improving the user experience of the foldable electronic device 100.

[0061] It should be noted that the housing assembly 10 has a receiving cavity (not shown), and the foldable electronic device 100 may also include a circuit board (not shown) and a battery (not shown), both of which can be disposed within the receiving cavity of the housing assembly 10. The circuit board may integrate the processor, power management module, storage unit, and baseband chip of the foldable electronic device 100.

[0062] In embodiments of the foldable electronic device 100 that include a flexible screen 60, the flexible screen 60 is communicatively connected to a processor, and a battery powers the flexible screen 60 and electronic components on the circuit board. In some embodiments, the foldable electronic device 100 may also include a camera module (not shown), which is communicatively connected to the circuit board, and a battery powers the camera module.

[0063] refer to Figure 9 , Figure 9 This is a schematic diagram of the structure of a foldable electronic device 100 provided in an embodiment of this application. The foldable electronic device 100 may include a radio frequency (RF) circuit 501, a memory 502 including one or more computer-readable storage media, an input unit 503, a display unit 504, a sensor 505, an audio circuit 506, a wireless fidelity (WiFi) module 507, a processor 508 including one or more processing cores, and a power supply 509, etc. Those skilled in the art will understand that... Figure 9The structure of the foldable electronic device 100 shown does not constitute a limitation on the foldable electronic device 100, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0064] The radio frequency (RF) circuit 501 can be used to send and receive information, or to receive and send signals during a call. Specifically, it receives downlink information from the base station and hands it over to one or more processors 508 for processing; additionally, it sends uplink data to the base station. Typically, the RF circuit 501 includes, but is not limited to, an antenna, at least one amplifier, a tuner, one or more oscillators, a Subscriber Identity Module (SIM) card, a transceiver, a coupler, a low-noise amplifier (LNA), a duplexer, etc. Furthermore, the RF circuit 501 can also communicate wirelessly with networks and other devices. This wireless communication can use any communication standard or protocol, including but not limited to GSM, GPRS, CDMA, WCDMA, LTE, email, and SMS.

[0065] Memory 502 can be used to store applications and data. The applications stored in memory 502 contain executable code. Applications can be composed of various functional modules. Processor 508 executes various functional applications and data processing by running the applications stored in memory 502. Memory 502 may primarily include a program storage area and a data storage area. The program storage area may store the operating system, applications required for at least one function (such as sound playback, image playback, etc.), etc.; the data storage area may store data created based on the use of the foldable electronic device 100 (such as audio data, phonebook, etc.). Furthermore, memory 502 may include high-speed random access memory and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device. Accordingly, memory 502 may also include a memory controller to provide access to memory 502 for processor 508 and input unit 503.

[0066] Input unit 503 can be used to receive input numbers, character information, or user characteristic information (such as fingerprints), and to generate keyboard, mouse, joystick, optical, or trackball signal inputs related to user settings and function control. Specifically, in one embodiment, input unit 503 may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display or touchpad, can collect user touch operations on or near it (such as user operations using fingers, styluses, or any suitable object or accessory on or near the touch-sensitive surface) and drive corresponding connection devices according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. The touch detection device detects the user's touch orientation and the signal generated by the touch operation, transmitting the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to the processor 508, and can receive and execute commands from the processor 508.

[0067] Furthermore, the touch-sensitive surface can cover the liquid crystal panel. When the touch-sensitive surface detects a touch operation on or near it, it transmits the information to the processor 508 to determine the type of touch event. Subsequently, the processor 508 provides corresponding visual output on the liquid crystal panel according to the type of touch event.

[0068] Display unit 504 can be used to display information input by the user or information provided to the user, as well as various graphical user interfaces of the foldable electronic device 100. These graphical user interfaces can be composed of graphics, text, icons, video, and any combination thereof. Display unit 504 may include the aforementioned liquid crystal panel.

[0069] Although Figure 9 In this embodiment, the touch-sensitive surface and the liquid crystal panel are two separate components for implementing input and output functions. However, in some embodiments, the touch-sensitive surface and the liquid crystal panel can be integrated to achieve both input and output functions. It is understood that the display screen may include an input unit 503 and a display unit 504.

[0070] The foldable electronic device 100 may also include at least one sensor 505, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor. The ambient light sensor can adjust the brightness of the LCD panel according to the ambient light level, and the proximity sensor can turn off the LCD panel and / or backlight when the foldable electronic device 100 is moved to the ear. As a type of motion sensor, a gravity acceleration sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition-related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the foldable electronic device 100, such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0071] The audio circuit 506 provides an audio interface between the user and the foldable electronic device 100 via the speaker 40b and a microphone. The audio circuit 506 converts received audio data into electrical signals, transmits them to the speaker 40b, and the speaker 40b converts them into sound signals for output. Conversely, the microphone converts collected sound signals into electrical signals, which are received by the audio circuit 506, converted back into audio data, and then processed by the processor 508 before being transmitted via the radio frequency circuit 501 to, for example, another foldable electronic device 100, or output to the memory 502 for further processing. The audio circuit 506 may also include a headphone jack to facilitate communication between a peripheral headset and the foldable electronic device 100.

[0072] WiFi (Wireless Fidelity) is a short-range wireless transmission technology. The foldable electronic device 100, through the WiFi module 507, can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 9 The wireless fidelity module 507 is shown, but it is understood that it is not a necessary component of the foldable electronic device 100 and can be omitted as needed without changing the nature of the invention.

[0073] The processor 508 is the control center of the foldable electronic device 100. It connects various parts of the foldable electronic device 100 via various interfaces and lines. By running or executing applications stored in the memory 502 and calling data stored in the memory 502, it performs various functions and processes data of the foldable electronic device 100, thereby providing overall monitoring of the foldable electronic device 100. Optionally, the processor 508 may include one or more processing cores; preferably, the processor 508 may integrate an application processor and a modem processor, wherein the application processor mainly handles the operating system, user interface, and applications, and the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 508.

[0074] The foldable electronic device 100 also includes a power supply 509 for supplying power to the various components. Preferably, the power supply 509 can be logically connected to the processor 508 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system. The power supply 509 may also include one or more DC or AC power supplies, recharging systems, power fault detection circuits, power converters or inverters, power status indicators, and other arbitrary components.

[0075] although Figure 9 As not shown in the diagram, the foldable electronic device 100 may also include a Bluetooth module, etc., which will not be described in detail here. In specific implementation, the above modules can be implemented as independent entities, or they can be arbitrarily combined and implemented as the same or several entities. For the specific implementation of the above modules, please refer to the previous method embodiments, which will not be described in detail here.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
