Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.
It should be noted that, two electronic devices are referred to herein, one is a foldable device, and the other is an electronic device for controlling the foldable device, and for convenience of distinction, the foldable electronic device is hereinafter referred to as a main device, and the other electronic device for controlling the foldable device is referred to as an auxiliary device, and may also be referred to by other names such as a first electronic device or a second electronic device, which is not limited in this application.
The main device is foldableA sub-device. Such as a foldable cell phone, a foldable pad, a notebook, etc. Taking a foldable mobile phone as an example, please refer to fig. 1, which is a schematic structural diagram of the foldable mobile phone provided in the embodiment of the present application. As shown in fig. 1, the foldable phone includes a first body, a second body and a connecting device. The connecting device can drive the first body or the second body to rotate so as to change the included angle between the first body and the second body
Figure BDA0002009162160000071
The specific structure of the connecting device will be described later.
For example, only one screen may be disposed on the foldable mobile phone shown in fig. 1, that is, the first body and the second body are covered with a whole screen (the screen may be a flexible screen), and when the first body or the second body rotates, the screen is folded. Of course, the foldable mobile phone shown in fig. 1 may also be provided with two independent screens, for example, a screen is provided on the first body, and a screen is provided on the second body, in which case, the two screens may not be flexible screens. Of course, it is also possible to set only one screen on one body, and not set the screen but the keys on the other body, which is not limited in the embodiment of the present application.
The unfolding angle related to the embodiment of the present application, that is, the angle at which the main device (foldable electronic device) is opened, takes the foldable mobile phone shown in fig. 1 as an example, and the unfolding angle is an included angle between the first body and the second body
Figure BDA0002009162160000072
Such as included angles
Figure BDA0002009162160000073
When the angle is 0 degree, the mobile phone is closed and forms an included angle
Figure BDA0002009162160000074
And when the angle is 180 degrees, the mobile phone is completely opened. It will be appreciated that in other embodiments, the angle is such that the handset is fully open
Figure BDA0002009162160000075
Or greater than 180 degrees, which is not limited in the embodiments of the present invention.
It should be appreciated that the angles in FIG. 1 are for ease of understanding
Figure BDA0002009162160000076
May be the angle between the planes of the two bodies.

In the embodiment of the application, after the auxiliary device is connected with the main device, the auxiliary device can be used for controlling the main device to change the unfolding angle of the main device, so that the main device is controlled.
Fig. 2 is a schematic view of an application scenario provided in the embodiment of the present application. As shown in fig. 2, the application scenario includes a main device and an auxiliary device, where the main device is a foldable mobile phone, and the auxiliary device is a stylus pen.
After the foldable mobile phone is connected with the stylus pen (the connection process will be described later), when the stylus pen rotates by a certain angle under the operation of the user
Figure BDA0002009162160000077
In this case, the stylus pen may transmit indication information to the foldable phone, and the indication information may be used for indicating angle information (for example, the indication information is used for indicating an angle
Figure BDA0002009162160000078
). After receiving the indication information, the foldable mobile phone analyzes the angle information indicated by the indication information, and then controls to change the included angle l between the first body and the second body based on the angle information. It should be understood that angle lR includes angle
Figure BDA0002009162160000083
May be the same or different.
Of course, the stylus pen may also transmit other indication information to the foldable phone, such as indication information for indicating to unfold the phone 100 or fold the phone 100. For example, the indication information for indicating the angle information and other indication information for indicating to unfold or fold the mobile phone 100 may be sent separately, and may be sent by being packaged into a control command, which is not limited in the embodiment of the present application. Hereinafter, packing into a control command is taken as an example.
Therefore, the control method of the foldable electronic device (main device) provided by the embodiment of the application does not need a user to manually pull the foldable electronic device, but controls the unfolding angle of the foldable electronic device through other devices, so that the operation of the user is facilitated.

The following describes a host device, a Graphical User Interface (GUI) for such a host device, and embodiments for using such a host device. In some embodiments of the present application, the main device may be a portable device, such as a foldable cell phone, a foldable tablet, a notebook, etc. The portable device includes a device capable of performing communication (such as a wireless communication module, a mobile communication module, and the like), and a device capable of performing change of the deployment angle, such as a hinge system (described later).

Or other operating system. The above-described portable device may be other portable devices as long as data communication is enabled and the deployment angle is changed. It should also be understood that, in some other embodiments of the present application, the above-mentioned main device may also be other devices capable of implementing data communication and changing the deployment angle.
Taking the main device as a foldable mobile phone (such as the mobile phone in the application scenario shown in fig. 2) as an example, fig. 3 shows a schematic structural diagram of the mobile phone 100.
As shown in fig. 3, the mobile phone 100 may include a processor 110, an external memory interface 120, an internal memory 121, an antenna 1, an antenna 2, a mobile communication module 151, a wireless communication module 152, a sensor module 180, buttons 190, a display 194, a hinge system 191, and the like. Wherein the sensor module 180 may include a pressure sensor 180A, a fingerprint sensor 180H, a touch sensor 180K, etc. (the sensor module 180 may also include other sensors such as a temperature sensor, an ambient light sensor, a gyroscope sensor, etc., not shown in the figures).
It is to be understood that the illustrated structure of the embodiment of the present application does not specifically limit the mobile phone 100. In other embodiments of the present application, the handset 100 may include more or fewer components than shown, or some components may be combined, some components may be separated, or a different arrangement of components may be used. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.
The components of the handset 100 shown in figure 3 are described below.
Processor 110 may include one or more processing units, such as: the processor 110 may include an Application Processor (AP), a modem processor, a Graphics Processor (GPU), an Image Signal Processor (ISP), a controller, a memory, a video codec, a Digital Signal Processor (DSP), a baseband processor, and/or a neural-Network Processing Unit (NPU), etc. The different processing units may be separate devices or may be integrated into one or more processors. The controller may be a neural center and a command center of the cell phone 100, among others. The controller can generate an operation control signal according to the instruction operation code and the timing signal to complete the control of instruction fetching and instruction execution.
A memory may also be provided in processor 110 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that have just been used or recycled by the processor 110. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory. Avoiding repeated accesses reduces the latency of the processor 110, thereby increasing the efficiency of the system.
The processor 110 may be configured to analyze the control instruction received by the mobile phone 100, and then control the rotating shaft system 191 according to information (such as angle information, unfolding/folding, and the like) included in the analyzed control instruction, so as to drive the first body or the second body to rotate, so as to change the unfolding angle of the mobile phone 100, where a process of driving the first body or the second body to select by the rotating shaft system 191 will be described later.
Of course, the processor 110 may encapsulate data to be transmitted, and transmit the encapsulated data to an auxiliary device such as a stylus pen through the mobile communication module 151 or the wireless communication module 152.
It should be understood that a communication mode may be agreed between the mobile phone 100 and the stylus pen, and the communication mode may be agreed on the format of data, the meaning of parameters, and the like, so that when the mobile phone 100 parses a control command sent by the stylus pen, the parsing may be performed according to the agreed communication mode, and when the mobile phone 100 encapsulates data to be sent, the encapsulation may also be performed according to the agreed communication mode, so that the stylus pen can parse the encapsulated data, which will be described later with respect to the communication mode.
The internal memory 121 may be used to store computer-executable program code, which includes instructions. The processor 110 executes various functional applications of the cellular phone 100 and data processing by executing instructions stored in the internal memory 121. The internal memory 121 may include a program storage area and a data storage area. The storage program area may store an operating system, an application program (such as WeChat, Paibao, etc.) required by at least one function, and the like. The data storage area can store data (such as pictures, video, audio data, phone books, etc.) created during the use of the mobile phone 100.
The internal memory 121 may also be used to store an unlock fingerprint of the handset 100, and the like. The unlocking fingerprint is used to verify the fingerprint received by the mobile phone 100, and when the received fingerprint is consistent with the unlocking fingerprint, the verification is successful, otherwise, the verification fails.
The internal memory 121 may include a high-speed random access memory, and may further include a nonvolatile memory, such as at least one magnetic disk storage device, a flash memory device, a universal flash memory (UFS), and the like.
The function of the sensor module 180 is described below.
The pressure sensor 180A is used for sensing a pressure signal, and converting the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A may be disposed on the display screen 194.
The fingerprint sensor 180H is used to collect a fingerprint. The mobile phone 100 can utilize the collected fingerprint characteristics to unlock the fingerprint, access the application lock, take a photograph of the fingerprint, answer an incoming call with the fingerprint, and the like.
As an example, the fingerprint sensor 180H collects an unlocking fingerprint, which is used to verify the fingerprint received by the mobile phone 100, and then stores the unlocking fingerprint in the internal memory 121, and when the verification is successful, unlocks the mobile phone 100. In the embodiment of the present application, the user can control the mobile phone 100 through the auxiliary device, so the auxiliary device can collect the fingerprint of the user and send the collected fingerprint to the mobile phone 100. After the mobile phone 100 receives the fingerprint of the user sent by the auxiliary device through the wireless communication module 152 or the mobile communication module 151, the processor 110 may compare the received fingerprint with the unlocking fingerprint stored in the internal memory 121, and if the received fingerprint is consistent with the unlocking fingerprint stored in the internal memory 121, control the unlocking device; alternatively, after the mobile phone 100 receives the fingerprint of the user sent by the auxiliary device through the wireless communication module 152 or the mobile communication module 151, the fingerprint sensor 180H may compare the received fingerprint with the stored unlocking fingerprint, and if the comparison is consistent, the processor controls the unlocking device.
The touch sensor 180K is also referred to as a "touch panel". The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, which is also called a "touch screen". The touch sensor 180K is used to detect a touch operation applied thereto or nearby. The touch sensor 180K may pass the detected touch operation to the application processor to determine the touch event type. Visual output associated with the touch operation may be provided through the display screen 194. In other embodiments, the touch sensor 180K may be disposed on the surface of the mobile phone 100, different from the position of the display 194.
The mobile phone 100 implements the display function through the GPU, the display screen 194, and the application processor. The GPU is a microprocessor for image processing, and is connected to the display screen 194 and an application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 110 may include one or more GPUs that execute program instructions to generate or alter display information.
The display screen 194 is used to display images, video, and the like. The display screen 194 includes a display panel. The display panel may be a Liquid Crystal Display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (active-matrix organic light-emitting diode, AMOLED), a flexible light-emitting diode (FLED), a miniature, a Micro-oeld, a quantum dot light-emitting diode (QLED), or the like. In some embodiments, the cell phone 100 may include 1 or N display screens 194, with N being a positive integer greater than 1.
As can be seen from the foregoing, in the embodiment of the present application, the mobile phone 100 may have one display screen, or may have at least two display screens. Taking the mobile phone 100 with a display screen as an example, please refer to fig. 1, where the first body is provided with a display screen, and the second body is not provided with a display screen; or the second body is provided with a display screen, and the first body is not provided with the display screen; alternatively, the first body and the second body cover a complete display (e.g., a flexible screen) which is folded when the mobile phone 100 is folded.
When the first body and the second body cover a complete display screen, the display area on the first body and the display area on the second body on the display screen can be used as two independent display screens to display the same content or different contents, or the display screen can be used as a large screen to display an interface, which is not limited in the embodiment of the application.
Taking the mobile phone 100 with two display screens as an example, please continue to refer to fig. 1, and an independent display screen is disposed on both the first body and the second body. For example, when the mobile phone 100 includes two display screens, the two display screens may display the same content or different content, and the embodiment of the present application is not limited thereto.
The hinge system 191 is used to change the angle of the mobile phone 100, and the specific process will be described later.
The handset 100 may receive key 190 inputs, generating key signal inputs relating to user settings and function controls of the handset 100.
Although not shown in FIG. 3, the handset 100 may also include a camera, such as a front-facing camera, a rear-facing camera; audio modules (loudspeaker, receiver, microphone, earphone interface) and the like can be further included for realizing audio functions; a motor may also be included for generating a vibration alert (such as an incoming call vibration alert); indicators such as indicator lights may also be included to indicate charge status, charge level changes, and may also be used to indicate messages, missed calls, notifications, etc.
The structure of the stylus pen will be described below by taking the example where the auxiliary device is a stylus pen.
Fig. 4 is a schematic structural diagram of a stylus pen according to an embodiment of the present disclosure. As shown in FIG. 4, the stylus includes a communication module, a processing module, a sensor module, and a storage module.
The sensor module may include sensors such as an acceleration sensor and a gyroscope, and is configured to detect an included angle between the stylus pen and the horizontal direction, a rotation direction of the stylus pen, and the like.
And the processing module is used for processing the data detected by the sensor module, for example, encapsulating the data detected by the sensor module according to an agreed communication mode.
The storage module is used for storing the communication mode agreed between the stylus and the mobile phone 100, and other parameters, such as the initial angle E0 of the stylus relative to the horizontal direction, which will be described later.
The communication module may be a mobile communication module or a wireless communication module such as a bluetooth module. Taking the bluetooth module as an example, the bluetooth module can send the packaged data to the mobile phone 100.
The process of controlling the mobile phone 100 by the stylus described in fig. 4 is described as follows:
after the stylus pen is connected to the mobile phone 100, the sensor module in the stylus pen detects sensor data such as a rotation angle and a rotation direction of the stylus pen, and then sends the detected data to the processing module, the processing module encapsulates the data according to an agreed communication mode, and the encapsulated data is sent to the mobile phone 100 through the communication module. The mobile phone 100 receives the encapsulated data sent by the stylus pen, analyzes the encapsulated data according to an agreed communication mode to obtain a rotation angle, a rotation direction and the like, and then controls the rotating shaft system 191 to change the unfolding angle of the mobile phone 100 based on the rotation angle, the rotation direction and the like.
In some embodiments, the stylus pen may detect data through the sensor module when it detects that the stylus pen satisfies a certain condition, for example, a switch may be disposed on the stylus pen, and when the switch is pressed, the sensor module detects the data. Specifically, when the processing module in the stylus detects that the switch is pressed, the processing module may trigger the start sensor module to detect data.
Therefore, for the user, when the user needs to control the foldable mobile phone through the stylus pen, the switch on the stylus pen can be pressed.
In some embodiments of the present application, in order to prevent the user from triggering the switch by mistake, which may result in the sensor module being triggered by mistake to detect data, the stylus pen may detect data through the sensor module only when detecting that the switch is pressed for a long time. For example, when the stylus pen detects that the switch is pressed for a preset time (for example, 2 seconds), the sensor module is triggered to start to detect data, and when the stylus pen detects that the switch is released (bounced), the sensor module is turned off. That is, the user can press the switch on the stylus pen for a long time when controlling the mobile phone 100 by the stylus pen, and release the switch when not needed to control the mobile phone 100.
Of course, the stylus pen may have other ways to control the sensor module to detect data, for example, the stylus pen may detect data through the sensor module when detecting that a switch is triggered, and turn off the sensor module when the stylus pen detects that another switch is triggered. That is, the stylus pen is provided with two switches, wherein when one switch is triggered, the stylus pen can control the mobile phone 100, and when the other switch is triggered, the stylus pen stops controlling the mobile phone 100.
It should be understood that it may not be clear how to control the mobile phone 100 in detail when the user first uses the stylus to control the mobile phone 100, so the mobile phone 100 or the stylus may give the user some prompt. As one example, each switch on the stylus may be provided with identification information (e.g., a label) indicating the role of each switch for user operation.
As another example, after the mobile phone 100 is connected to a stylus pen, the mobile phone 100 may display an interface for controlling the process steps of the mobile phone 100 by the stylus pen (the interface for the process steps may be displayed after the initial connection, or the interface for the process steps may be displayed after each connection); or, after the mobile phone 100 is connected to the stylus pen, the stylus pen may output a prompt message (such as a voice output) to prompt the user to control the flow steps of the mobile phone 100 through the stylus pen; or after the mobile phone 100 and the stylus pen are connected, a control may be displayed on the display screen of the mobile phone 100, and when the control is triggered, an interface of the process step of controlling the mobile phone 100 by the stylus pen is popped up; the above are only some exemplary prompt manners for prompting the user to control the operation steps of the mobile phone 100 by using the stylus pen, and in practical applications, other prompt manners may be provided.
It should be noted that fig. 4 only illustrates that the auxiliary device is a stylus pen, in practical applications, the auxiliary device may also be other devices, such as a smart band, a watch, and the like, which is not limited in this embodiment of the present application.
The following description will be made by taking the mobile phone 100 shown in fig. 3 and the stylus pen shown in fig. 4 as examples, and taking the mobile phone 100 and the stylus pen as examples connected via bluetooth.
It should be appreciated that bluetooth pairing can be performed before two devices communicate data via bluetooth.
Illustratively, the bluetooth pairing process may include:
in the first step, the mobile phone 100 starts the bluetooth module, and the stylus starts the bluetooth module.
For example, the process of enabling the bluetooth function by the mobile phone 100 may be a process in the prior art, please refer to fig. 5, which is a schematic diagram of a GUI of the mobile phone 100 provided in an embodiment of the present application, as shown in fig. 5(a), when the control 501 is activated, the mobile phone 100 enables the bluetooth function.
For example, a switch control may be provided on the stylus pen, and when it is detected that the switch control is triggered, the stylus pen activates the bluetooth module. It will be appreciated that the switch used on the stylus for controlling activation of the bluetooth module and the switch described above (for triggering the sensor module) may be different switches.
In the second step, after the mobile phone 100 scans the stylus, the identification information of the stylus is displayed.
Referring to fig. 5(a), after the mobile phone 100 scans the stylus device, an identifier 502 of the stylus is displayed (the identifier may be a name of the stylus, may be set when the stylus leaves a factory, or may be user-defined, which is not limited in this embodiment of the present application).
Thirdly, when the mobile phone 100 detects an operation for triggering connection with the stylus pen, the mobile phone is connected with the stylus pen.
Referring to fig. 5(a), when detecting that the user triggers the control 503, the mobile phone 100 establishes a connection with the stylus pen; or when the mobile phone 100 detects that the user triggers the operation of the control 503, an interface as shown in fig. 5(b) is displayed, that is, the mobile phone 100 pops up a prompt message 504 to prompt the user whether to establish a connection with the stylus pen, and if the user selects yes, the mobile phone 100 establishes a bluetooth connection with the stylus pen.
Certainly, the process shown in fig. 5 is only an example of a process of establishing a bluetooth connection between the mobile phone 100 and the stylus pen, and other connection manners may also be used in practical applications, for example, before the bluetooth connection between the mobile phone 100 and the stylus pen is established, the user may be prompted to input a pairing code of the stylus pen, and after the mobile phone 100 detects that the user inputs the pairing code of the stylus pen, the connection is established with the stylus pen, which is not limited in the embodiment of the present application.
After the handwriting pen establishes bluetooth connection with the mobile phone 100, the user can control the unfolding angle of the mobile phone 100 through the handwriting pen. It should be noted that, after the stylus pen and the mobile phone 100 establish the bluetooth connection, data transmission between the stylus pen and the mobile phone 100 may be encapsulated in an agreed communication manner.
It should be understood that the appointed communication mode used when the mobile phone 100 transmits data to the stylus pen and the appointed communication mode used when the stylus pen transmits data to the mobile phone 100 may be different, and will be separately described below.
The following describes the conventional communication method used when the stylus pen sends data to the mobile phone 100.
Fig. 6 shows an example of meanings of different parameter values defined by an agreed communication method adopted when the stylus pen sends data to the mobile phone 100. As shown in fig. 6, when the value of the parameter is 1, it represents 0 degree, when the value of the parameter is 2, it represents 30 degrees, when the value of the parameter is 6, it represents that the control state is entered, and when the value of the parameter is 7, it represents that the control state is exited, and so on. When the stylus pen sends data to the mobile phone 100, the data may be encapsulated by using different values shown in fig. 6, for example, if the initial angle E0 of the stylus pen is 30 degrees, it can be known from the table shown in fig. 6 that the value of the parameter corresponding to 30 degrees is 2, and the data sent by the stylus pen to the mobile phone 100 includes 2. It should be understood that, in fig. 6, the values of the parameters are shown as decimal numbers, and actually, the parameters may also be presented in other manners, such as being represented by different characters (such as letters), or the values of the parameters may also be binary numbers, and the embodiments of the present application are not limited thereto.
Fig. 7(a) shows an example of a data transmission format defined by a convention communication method adopted when a stylus pen transmits data to the mobile phone 100. As shown in fig. 7(a), the data transmission format includes six fields, and a parameter in the first field is used to indicate an access code (access code); a parameter in the second field is used to indicate a header field (header); the value in the third field is used for indicating to enter or exit the screen control state; the values of each of the fourth to fifth fields may be used to indicate sensor data of the stylus; for example, the value in the fourth field is used to indicate the rotated angle E1 of the stylus, the value in the fifth field is used to indicate the unfolding or folding, and the value in the sixth field is used to indicate the initial angle E0 of the stylus. The initial angle E0 may be the angle of the stylus with respect to the horizontal. The rotated angle E1 may be an angle between the mobile phone and the horizontal direction after the mobile phone is rotated from the initial angle. Thus, the absolute value of the difference between E1 and E0 is how much the stylus has been rotated.
As an example, in the data format shown in fig. 7(a), the value of the fifth field may be determined by the stylus pen according to the user operation, for example, a switch 1 and a switch 2 are set on the stylus pen, when the user wants to control the mobile phone 100 to expand by using the stylus pen, the user triggers the switch 1, and when the stylus pen detects that the switch 1 is triggered, the value of the third field is 8; when the user wants to control the mobile phone 100 to fold by using the stylus pen, the user triggers the switch 2, and when the stylus pen detects that the switch 2 is triggered, the value of the third field is 9.
It should be understood that, as mentioned above, the stylus pen detects that the switch is pressed for a long time, and starts to control the mobile phone 100, so in practical applications, the stylus pen detects that the switch 1 is pressed for a long time, and starts to control the mobile phone 100 to unfold, and when the stylus pen detects that the switch 1 is released, stops controlling the mobile phone 100; when the stylus pen detects that the switch 2 is pressed for a long time, the mobile phone 100 starts to be controlled to fold, and when the stylus pen detects that the switch 2 is released, the mobile phone 100 stops being controlled. That is, the user can control whether the cell phone 100 is unfolded or folded using different switches on the stylus.
As another example, the value of the fifth field may also be determined by the stylus pen according to its own rotation direction, for example, if the stylus pen detects that the angle between the user operating the stylus pen and the horizontal plane is increased (i.e. the difference between E1 and E0 is a positive number), the value of the fifth field of the stylus pen is 8, and if the stylus pen detects that the user operating the stylus pen and the horizontal plane is decreased (i.e. the difference between E1 and E0 is a negative number), the value of the fifth field is determined by the stylus pen to be 9. That is, in this example, the user realizes an effect of controlling the mobile phone 100 to be unfolded or folded by changing the rotation direction of the stylus pen.
It should be understood that, in fig. 7(a), for convenience of distinction, the parameters in the third field to the sixth field are distinguished by parameter 1, parameter 2, parameter 3, and parameter 4, respectively, and the values of the parameters 1 to 4 may be values in the table shown in fig. 6.
It should be noted that, in the data transmission format shown in fig. 7(a), for example, the fourth field is used to indicate the angle E1, the fifth field is used to indicate the unfolding or folding, and the sixth field is used to indicate the initial angle E0, actually, it is not limited to which field is used to indicate the angle E1, for example, the fourth field is used to indicate the initial angle E0, the fifth field is used to indicate the unfolding or folding, and the sixth field is used to indicate the angle E1.
Therefore, when the stylus pen sends data to the mobile phone 100, the data may be encapsulated according to the meaning of the value shown in fig. 6 and the data transmission format shown in fig. 7(a), and the encapsulated data is sent to the mobile phone 100.
The process of encapsulating data with the stylus shown in fig. 4 is described below.
The sensor module in the stylus pen collects sensor data of the stylus pen, and it is assumed that the sensor data collected by the sensor module includes an initial angle E0 between the stylus pen and the horizontal plane being 0 degree, and an included angle E1 between the stylus pen and the horizontal plane after rotation being 30 degrees. The sensor module can send sensor data to the processor module, the processor module determines that an included angle between the stylus pen and the horizontal plane is increased, namely corresponding to expansion, the storage module in the stylus pen stores meanings represented by each value shown in fig. 6, the processing module can inquire a corresponding value, namely 1, when the E0 is 0 degrees, a corresponding value, namely 2, when the E1 is 30 degrees, a corresponding value, namely 8, in the storage module, the processor module fills values in different fields according to a data transmission format shown in fig. 7(a), and packaged data are obtained. The communication module sends the encapsulated data to the handset 100.
For example, please refer to fig. 8, which is a schematic diagram of packaged data sent by the stylus to the mobile phone 100. As shown in fig. 8, the encapsulated data includes six fields, where a first field is an access code, a second field is a header, a third field is null, a value of a parameter in the fourth field is 2, a value of a parameter in the fifth field is 8, and a value of a parameter in the sixth field is 1.
The following describes a process of parsing the encapsulated data after the handset 100 receives the encapsulated data.
After receiving the encapsulated data, the mobile phone 100 may determine the value of each of the access code, the header, and the third to sixth fields, and determine the meaning of the value in each field according to the table shown in fig. 6.
For example, the access code may include an identity ID of the stylus pen, and after the mobile phone 100 receives the encapsulated data sent by the stylus pen, the identity ID of the stylus pen may be obtained by analyzing the access code in the data to verify whether the stylus pen is a device currently establishing a bluetooth connection with the mobile phone 100. For example, when the mobile phone 100 establishes a bluetooth connection with the stylus pen, the identity ID of the stylus pen may be stored, and after the mobile phone 100 receives the encapsulated data sent by the stylus pen, the access code included in the data is analyzed, and if the acquired identity ID is consistent with the stored identity ID, it is determined that the stylus pen is the device currently connected with the mobile phone 100. The identity ID may be a Media Access Control (MAC) address, an Internet Protocol (IP) address, a device identifier (such as a product model), and the like, which is not limited in this embodiment.
The header may include information indicating bytes occupied by each of the third to sixth fields. Handset 100 may accurately distinguish the different fields based on the header. Illustratively, the number of bytes occupied by each of the third to sixth fields may be the same or different. For example, bytes 1-72 are a first field, bytes 73-127 are a second field, bytes 128-129 are a third field for indicating entry or exit of a screen control state, bytes 130-131 are a fourth field for indicating an angle E1 of the stylus, bytes 132-133 are a fifth field for indicating expansion or collapse, and bytes 134-135 are a sixth field for indicating an initial angle E0 of the stylus.
After determining each field, the mobile phone 100 determines the value of each field, and determines the meaning of the value of each field according to the table shown in fig. 7. For example, the value in the fifth field indicates that the cell phone 100 is deployed, and the cell phone 100 may open the cell phone 100 by a certain angle according to the absolute value of the difference between E1 (meaning of the value in the third field) and E0 (meaning of the value in the sixth field), where the angle may be the same as or different from the absolute value of the difference between E1 and E0.
The following describes the conventional communication method used when the mobile phone 100 transmits data to the stylus pen.
Fig. 9 shows an example of meaning of different values defined by an agreed communication method adopted when the mobile phone 100 transmits data to the stylus pen. As shown in fig. 9, when the value of the parameter is 0, it represents that the response of the mobile phone 100 is successful, and when the value of the parameter is 1, it represents that the response of the mobile phone 100 is failed.
Fig. 7(b) shows an example of a data transmission format defined by an agreed communication method adopted when the mobile phone 100 transmits data to the stylus pen. As shown in fig. 7(b), the data transmission format includes a first field, a second field, and a third field. The first field is an access code (access code), the second field is a header field (header), and the third field includes 1 value, which is used to indicate success or failure of the response of the mobile phone 100.
It should be understood that the third field in the data transmission format shown in fig. 7(b) is a decimal number, and may actually be represented by a character, or represented by a binary number, etc., and the embodiment of the present application is not limited.
When the mobile phone 100 sends data to the stylus pen, the data may be encapsulated according to the data transmission format shown in fig. 7(b) and the meaning of the parameter value shown in fig. 9, and the encapsulated data may be sent to the stylus pen.
For example, please refer to fig. 10, which is a schematic diagram illustrating data transmitted from the mobile phone 100 to the stylus. As shown in fig. 10, the value in the third field of the data sent by the mobile phone 100 to the stylus pen is 0, and as can be seen from fig. 9, the value of 0 represents that the response is successful.
The following describes a process of decapsulating data after the stylus pen receives the encapsulated data sent by the mobile phone 100.
After receiving the encapsulated data sent by the mobile phone 100, the stylus pen may determine values of the access code, the header, and the third field, and determine a meaning of the value in the third field according to the table shown in fig. 9.
For example, the access code may include an identity ID of the mobile phone 100, and after the stylus pen receives the encapsulated data sent by the mobile phone 100, the stylus pen may obtain the identity ID of the mobile phone 100 by analyzing the access code in the data, so as to verify whether the mobile phone 100 is a device currently connected to the stylus pen.
The header may include a number of bytes used to indicate the number of bytes occupied by each field. The stylus can accurately determine each byte from the header. Taking the third field in the data shown in fig. 10 occupying two bytes as an example, after the stylus receives the encapsulated data sent by the mobile phone 100, it can be determined that the 1 st to 72 th bytes are the first field, the 73 th to 127 th bytes are the second field, and the 128 th and 129 th bytes are the third fields. The stylus determines the meaning corresponding to the value of the third field based on the table shown in fig. 9, and the value in the third field is used to indicate success or failure of the response of the mobile phone 100.
The following describes a process of controlling the unfolding angle of the mobile phone 100 by the stylus pen.
Hereinafter, the first switch provided on the stylus pen is taken as an example, and the first switch is used to turn on the function of controlling the unfolding angle of the mobile phone 100 by the stylus pen.
Fig. 11 is a schematic flowchart illustrating a method for controlling a foldable electronic device according to an embodiment of the present application. The method may be applied to an auxiliary device such as a stylus as described above. As shown in fig. 11, the flow of the method includes:
s1101: the handwriting pen detects that a user inputs a first operation.
As can be seen from the foregoing, the stylus pen may be provided with a first switch, and when the user wants to control the unfolding angle of the mobile phone 100 through the stylus pen, the user may press the first switch. Therefore, the first operation may be an operation in which the first switch is pressed.
S1102: the stylus pen responds to a first operation and sends a first instruction to the mobile phone 100, and the first instruction is used for indicating the mobile phone 100 to enter a screen control state; the screen control state is used to indicate that the deployment angle is ready to be adjusted.
Illustratively, after detecting that the first switch is continuously pressed for a preset time period, the stylus pen sends a first instruction to the mobile phone 100.
For example, the stylus pen may use the data transmission format shown in fig. 7(a) to package the data to be transmitted into the first command, please refer to fig. 12, which is a schematic diagram of the first command. As shown in fig. 12, the value of the third field in the first instruction is 6, that is, the third field is used to indicate that the screen control state is entered, and the fourth to sixth fields may be empty.
S1103: the handset 100 enters a screen control state.
For example, when the mobile phone 100 enters the screen control state, preparations may be made for changing the unfolding angle, such as recording the initial state of the mobile phone 100, where the initial state includes which body of the mobile phone 100 is currently in contact with the horizontal plane, the current unfolding angle (hereinafter referred to as the initial unfolding angle), and the like. For another example, the power is applied to the shaft system 191, and the specific process will be described later.
After the mobile phone 100 records an initial state (for example, a current unfolding angle), the unfolding angle is adjusted in the initial state, for example, the current unfolding angle is 30 degrees, the mobile phone 100 receives an instruction, the angle information carried in the instruction is 30 degrees, and the instruction indicates that the mobile phone 100 is unfolded, and then the mobile phone 100 is increased by 30 degrees on the basis of the current unfolding angle, that is, after the adjustment, the unfolding angle is 60 degrees.
S1104: the mobile phone 100 feeds back a second instruction to the stylus pen, wherein the second instruction is used for indicating that the mobile phone 100 successfully responds.
The mobile phone 100 may encapsulate the data to be transmitted according to the data transmission format shown in fig. 7(b), obtain a second instruction, and transmit the second instruction to the stylus pen.
For example, please refer to fig. 13, which is a schematic diagram of the second instruction. As shown in fig. 12, the value of the third field in the second instruction is 0, which is used to indicate that the response of the mobile phone 100 is successful.
It should be understood that the success of the response may be used to indicate that the mobile phone 100 successfully receives the first instruction, or to indicate that the mobile phone 100 successfully enters the screen control state, and the embodiment of the present application is not limited thereto.
S1105: the stylus detects a first angle of rotation of itself.
The sensor module is arranged on the stylus pen, comprises a gyroscope or an angular velocity sensor, and can be used for detecting the rotation angle of the stylus pen.
As an example, the stylus pen may detect an angle of the stylus pen with the horizontal plane, i.e., an initial angle E0, through the sensor module when detecting that the first switch is pressed, and record the initial angle E0. The sensor module can detect the included angle between the stylus and the horizontal plane in real time or periodically. When the stylus is rotated by the user, the sensor module may detect the rotated angle E1 (the angle from the horizontal after the stylus is rotated). The first angle may be the difference between E1 and E0.
S1106: the stylus pen sends a third instruction to the mobile phone 100, where the third instruction may be used to indicate the first angle and may also be used to indicate to fold or unfold the mobile phone 100.
As can be seen from the foregoing, the stylus pen can determine whether to unfold or fold the mobile phone 100 according to the difference between E1 and E0, for example, when the difference between E1 and E0 is positive, the mobile phone 10 is unfolded, and when the difference between E1 and E0 is negative, the mobile phone 100 is folded. The stylus pen may encapsulate data to be transmitted in an agreed communication manner to obtain a third instruction.
For example, please refer to fig. 14, which is a schematic diagram of the third instruction. As shown in fig. 14, the value of the third field in the third instruction is null, the value of the fourth field represents the rotated angle E1, the value of the fifth field represents the expansion, and the value of the sixth field represents the initial angle E0. In the example shown in FIG. 14, the third command includes an initial angle E0 and a rotated angle E1, the absolute value of the difference between the initial angle E0 and the rotated angle E1, i.e., how many degrees the stylus has been rotated.
S1107: the mobile phone 100 controls the unfolding angle of the mobile phone 100 to be the second angle based on the third instruction.
After receiving the third command, the mobile phone 100 may parse the third command, determine an absolute value of a difference between E1 and E0, obtain a rotation angle of the stylus pen, and determine the unfolding or folding indicated in the third command.
As an example, the rotation angle of the mobile phone 100 may be equal to the rotation angle of the stylus.
For example, taking the initial state of the mobile phone 100 including the first body contacting the horizontal plane and the initial unfolding angle of the mobile phone 100 being 30 degrees as an example, if the third instruction indicates to unfold the mobile phone 100 and indicates to rotate the stylus pen by 30 degrees, the mobile phone 100 controls the rotating shaft system 191 to drive the second body to rotate by 30 degrees, and the final unfolding angle of the mobile phone 100 is 60 degrees. If the third instruction indicates to fold the mobile phone 100 and the rotation angle of the stylus pen is 30 degrees, the mobile phone 100 controls the rotation axis system 191 to drive the second body to rotate 30 degrees, and if the initial unfolding angle of the mobile phone 100 is 30 degrees, the final unfolding angle of the mobile phone 100 is 0 degree.
As another example, the mobile phone 100 may calculate another angle based on the rotation angle of the stylus pen, and the rotation angle of the mobile phone 100 is the calculated angle.
For example, taking the initial state of the mobile phone 100 including the first body contacting the horizontal plane and the initial unfolding angle of the mobile phone 100 being 30 degrees as an example, the third instruction indicates that the rotation angle of the stylus pen is 30 degrees, and the third instruction indicates that the mobile phone 100 is unfolded, the mobile phone 100 calculates another angle value based on the 30 degrees, and controls the rotation shaft system 191 to drive the second body to rotate the calculated angle. Thus, the final deployment angle of the handset 100 is the sum of the initial deployment angle and the calculated angle.
For example, the mobile phone 100 may calculate the rotation angle according to the following formula (1):
Figure BDA0002009162160000171
where E1 is the rotated angle of the stylus pen, E0 is the initial angle of the stylus pen, and V0 is a preset angle, where the preset angle may be the maximum angle that the mobile phone 100 can rotate, for example, V0 is 180 degrees.
The cell phone 100 can calculate the rotation angle V according to the values of E1 and E0 and the value of V0 carried in the third command. Thus, the angle of rotation of the handset 100 is V, rather than (E1-E0).
S1108: the handset 100 sends a fourth instruction to the stylus indicating that the response was successful.
For example, after the rotation angle of the mobile phone 100 is successful, a fourth instruction may be sent to the stylus pen to indicate that the rotation is successful. Of course, after the rotation of the mobile phone 100 fails (for example, the rotation shaft system 191 is abnormally operated and cannot be powered on, and the like, so that the unfolding angle is not changed, or the mobile phone 100 is unfolded to the maximum angle), an instruction for the rotation failure may also be sent to the stylus pen.
As an example, when the stylus pen receives an instruction indicating that the rotation of the mobile phone 100 has failed, a prompt message may be output to prompt the user that the rotation of the mobile phone 100 has failed. Of course, after the rotation of the mobile phone 100 fails, the mobile phone may output a prompt message to prompt the user of the rotation failure.
In other embodiments, the mobile phone 100 may not need to send the fourth instruction to the stylus pen, and the embodiment of the present application is not limited thereto.
S1009: the stylus pen detects the second operation.
For example, the second operation may be an operation in which the first switch on the stylus pen is released.
S1010: the stylus pen sends a fifth instruction to the mobile phone 100 in response to the second operation, the fifth instruction being used for instructing the mobile phone 100 to exit the screen control state.
For example, the fifth instruction is similar to the first instruction, and is not repeated here.
S1111: the handset 100 exits the screen control state.
For example, when the mobile phone 100 exits the screen control state, the hinge system 191 may be turned off, such as by powering down the hinge system 191; or deleting the related data of the recorded initial state.
The control flow of the stylus to the mobile phone 100 is described below by way of example.
Example 1:
fig. 15 is a schematic flow chart illustrating the process of controlling the unfolding angle of the mobile phone 100 by the pen. As shown in fig. 15, the process includes:
the first process is as follows: the pen is placed horizontally, the mobile phone 100 is closed (the expansion angle is 0 degree), and the second body is in contact with the horizontal plane. After detecting that the switch K1 is pressed for a long time, the stylus pen sends a first instruction to the mobile phone 100, where a first field in the first instruction includes an access code, a second field includes a header, a value in a third field is 6, the third field is used to indicate that the mobile phone 100 enters a screen control state, and other fields are empty. The mobile phone 100 receives the first instruction, enters a screen control state, and records an initial state, wherein the initial state includes an initial unfolding angle of 0 degree.
The second process: when the stylus pen is rotated by 30 degrees by the user, the stylus pen sends a second instruction to the mobile phone 100, where a first field in the second instruction includes an access code, a second field includes a header, a third field is empty, a value in a fourth field is 2, a value in a fifth field is 8, and a value in a sixth field is 1. After the mobile phone 100 receives the second instruction, the meaning of each value is analyzed according to the meaning of the value shown in fig. 6, and it is determined that 60 degrees needs to be rotated according to the formula (1), that is, the mobile phone 100 controls the rotating shaft system 191 to drive the first body to rotate 60 degrees, and the final expansion angle is 60 degrees.
In the third process, the stylus pen is rotated by the user for 30 degrees, the stylus pen sends a third instruction to the mobile phone 100, and in the third instruction, the value in the fourth field is 3, the value in the fifth field is 8, and the value in the sixth field is 2. After the mobile phone 100 receives the third instruction, the meaning of each value is analyzed according to the meaning of the value shown in fig. 6, and it is determined that 60 degrees needs to be rotated according to the above formula (1), then the mobile phone 100 controls the rotating shaft system 191 to drive the first body to continue to rotate by 60 degrees, and the final expansion angle is 120 degrees.
A fourth process: the stylus pen is rotated by the user for 30 degrees, the stylus pen sends a fourth instruction to the mobile phone 100, where a value of a fourth field in the fourth instruction is 4, a value of a fifth field is 8, and a value of a sixth field is 3. After receiving the fourth instruction, the mobile phone 100 analyzes the meaning of each value according to the meaning of the value shown in fig. 6, and determines that the first body needs to rotate for 60 degrees continuously according to the formula (1), so that the mobile phone controls the rotating shaft system 191 to drive the first body to rotate for 60 degrees continuously, and the final expansion angle is 180 degrees.
The fifth process: and after detecting that the switch K1 is released, the stylus pen sends a fifth instruction to the mobile phone 100, wherein a value in a third field in the fifth instruction is 7. After receiving the fifth instruction, the mobile phone 100 exits the screen control state.
It should be noted that in the process shown in fig. 15, the screen may be automatically lighted up in the process of opening the mobile phone 100 from 0 degree to 180 degrees.
As an example, the mobile phone 100 may determine which screen to illuminate based on the current deployment angle. For example, if the current unfolding angle is within the first angle range, the mobile phone 100 lights up the main screen; if the current expansion angle is within the second angle range, the secondary screen is turned on by the mobile phone 100, and the minimum value of the second angle range is greater than the maximum value of the first angle range.
For example, the main screen and the auxiliary screen on the mobile phone 100 can be set by the user; or, the main screen and the sub-screen on the mobile phone 100 may be default screens set when the mobile phone 100 leaves a factory; or, the main screen on the mobile phone 100 may be a rotated main screen, and the sub-screen is a screen on the main body that is not rotated; alternatively, the mobile phone 100 detects which screen the user gazes at (for example, if the camera on the first body detects a face, the user gazes at the screen on the first body), and which screen is the main screen.
Illustratively, continuing with fig. 15 as an example, when the mobile phone 100 detects that the unfolding angle is 60 degrees, the main screen may be lighted, assuming that the main screen is a screen of the rotated body (i.e., a screen on the first body). After the main screen is lightened by the mobile phone 100, a screen locking interface can be displayed; or a fingerprint sensor is arranged on the switch K1 on the stylus pen, and the fingerprint sensor can be used for collecting a fingerprint of a user and sending the collected fingerprint to the mobile phone 100, after the mobile phone 100 lights the main screen, whether the fingerprint is consistent with the stored fingerprint can be verified, and if so, the device is unlocked, that is, the main screen is lighted and then the main interface is displayed. For example, after the main screen is lit by the mobile phone 100, a prompt message (e.g., a voice prompt) may be sent to the stylus pen, where the prompt message is used to prompt the user to enter a fingerprint at the side of the stylus pen, and the stylus pen sends the fingerprint to the mobile phone 100 after detecting that the user enters the fingerprint. For example, the fingerprint sensor of the stylus pen may be integrated with the switch K1 shown in fig. 15, that is, when the user presses the switch K1 for a long time to control the mobile phone 100 by the stylus pen, the fingerprint sensor of the switch K1 collects the fingerprint of the user and then transmits the collected fingerprint to the mobile phone 100.
For example, after the main screen is lighted up, the screen locking interface may be displayed first, and when the fingerprint verification is successful, the main interface is entered, or the mobile phone 100 may verify the fingerprint first, and after the fingerprint verification is successful, the main interface may be directly displayed without displaying the screen locking interface. In a second process, the secondary screen may be in a screen-off state.
In the third process, when the mobile phone 100 detects that the mobile phone is opened by 120 degrees, the secondary screen may be lit, and the same content as that of the main screen may be displayed after the secondary screen is lit, that is, the display interfaces of the secondary screen and the main screen are the same. When the mobile phone 100 detects that the mobile phone is opened by 180 degrees, the main screen and the sub-screen are used as a complete screen to display an interface, that is, the mobile phone 100 can be used as a pad. The specific process will be described later.
Example 2:
fig. 16 is a schematic flow chart illustrating the process of controlling the unfolding angle of the mobile phone 100 by the pen. As can be seen from a comparison between the process shown in fig. 16 and the process shown in fig. 15, in the flow shown in fig. 16, the stylus pen is gradually changed from the vertically-disposed state to the horizontally-disposed state, and therefore, the unfolding angle of the mobile phone 100 is adjusted from 180 degrees to 0 degrees.
In the process shown in fig. 16, the screen of the mobile phone 100 may be gradually turned off from 180 degrees to 0 degrees.
Illustratively, in the example shown in fig. 16, the unfolding angle of the mobile phone 100 is 180 degrees (the first process), and the main screen and the sub-screen can be used as a complete display screen to display an interface. In the process of decreasing the spread angle from 180 degrees to 120 degrees (second process), the main screen and the sub-screen may display the same interface as two separate display screens. In the process (third process) of reducing the spread angle from 120 degrees to 60 degrees, the sub-screen may be turned off, and in the process of reducing the spread angle from 60 degrees to 0 degrees, the main screen may be turned off.
The process of controlling the deployment angle by the pivot system 191 in the handpiece 100 is described below.
Referring to fig. 17, which is a schematic view of a spindle system 191, as shown in fig. 17, the spindle system 191 includes a first spindle system and a second spindle system, where the first spindle system may be used to drive the first body to rotate, and the second spindle system may be used to drive the second body to rotate. As can be seen from the foregoing, when the mobile phone 100 enters the screen control state, the initial state of the mobile phone 100 can be recorded, where the initial state includes which body of the mobile phone 100 is in contact with the desktop, and if the first body is in contact with the desktop, the first rotating shaft system of the mobile phone 100 drives the first body to rotate; if the second body contacts the desktop, the mobile phone 100 controls the second hinge system to rotate the second body.
In some embodiments, the cell phone 100 can determine which body is in contact with the object through a pressure sensor. For example, when one body of the mobile phone 100 contacts a desktop, a pressure sensor on the body generates a pressure signal, and the mobile phone 100 can determine that the body contacts the desktop, the other body is controlled to rotate by a rotating shaft system corresponding to the other body.
In other embodiments, the mobile phone 100 may also determine which body does not need to rotate through the ambient light sensor, for example, the first body and the second body are both provided with the ambient light sensor, and if the ambient light sensor on the first body detects that the ambient light is weak, the mobile phone 100 may rotate the second body. For example, if the user holds the first body of the mobile phone 100, the ambient light sensor on the first body detects that the ambient light is weak, and the mobile phone 100 rotates the second body.
In other embodiments, the mobile phone 100 may determine which body does not need to rotate in other manners, for example, if the mobile phone 100 determines that the contact area between the first body and the hand of the user is larger, the first body does not need to rotate, and the second body rotates.
Taking the first rotating shaft system as an example, please refer to fig. 18(a), the first rotating shaft system includes a first cylinder and a second cylinder, the second cylinder may be hollow and is sleeved outside the first cylinder, that is, the outer diameter of the first cylinder is smaller than the inner diameter of the second cylinder. The first cylinder is connected with the first connecting body, and the first connecting body is connected with the first body, so when the first cylinder rotates, the first body is driven to rotate through the first connecting body.
The first cylinder can have magnetism, and four magnets are arranged outside the first cylinder and inside the second cylinder and used for driving the first cylinder to rotate. It will be appreciated that the four magnets may be metal bodies having an outer surface wrapped around a wire, the metal bodies being magnetic when the wire is energized.
For example, with continued reference to fig. 18(b), the first pillar itself has magnetic properties, and half of the first pillar is S-level and the other half is N-level. The wires are wound outside the 4 metal bodies, the wires on the periphery of each metal body are connected with a power supply, and when the wires on the periphery of one metal body are electrified, the metal body generates magnetism and can attract or repel the first cylinder, so that the first cylinder is caused to rotate. With continued reference to fig. 18(b), when the switch S3 is closed, the side of the third magnet facing the first column is in S-stage, attracting N-stage of the first column.
Fig. 19 is a schematic diagram showing two forms of the mobile phone 100. When the second body contacts with the table top, the cross section of the first rotating shaft system is as shown in fig. 19(a), and the first cylinder drives the first body to rotate. As an example, the mobile phone 100 may be provided with four magnets, namely a first magnet, a second magnet, a third magnet, and a fourth magnet. Wherein the positions of the four magnets do not change. For example, when the included angle between the first body and the second body is 0, the S-stage of the first column faces the first magnet, because the side of the first magnet facing the first column is N-stage. When the included angle between the first body and the second body is 90 degrees, the S-level of the first column body is over against the second magnet, because the side of the second magnet over against the first column body is N-level at the moment.
When the first body contacts with the desktop, the cross section of the second rotating shaft system is as shown in fig. 19(b), and the first cylinder in the second rotating shaft system drives the second body to rotate. As an example, the mobile phone 100 may be provided with four magnets, namely a first magnet, a second magnet, a third magnet, and a fourth magnet. Wherein the positions of the four magnets do not change. For example, when the included angle between the first body and the second body is 0, the S-stage of the first column faces the first magnet, because the side of the first magnet facing the first column is N-stage. When the included angle between the first body and the second body is 90 degrees, the S-level of the first column body is over against the second magnet, because the side of the second magnet over against the first column body is N-level at the moment.
It should be understood that, in order to control a certain metal body to generate magnetism, a switch may be disposed between the conducting wire and the power source at the periphery of each metal body in the first rotating shaft system or the second rotating shaft system.
The following description will take an example in which the second body of the mobile phone 100 contacts with a desktop and the first body is driven to rotate by the first rotating shaft system.
When the mobile phone 100 enters the screen control state, the initial state is recorded, where the initial state may include an initial deployment angle, the mobile phone 100 receives a control instruction sent by the stylus pen, and assuming that angle information indicated by the control instruction is 30 degrees, the mobile phone 100 needs to control the first body to rotate by 30, that is, the final deployment angle is 60 degrees (assuming that the initial deployment angle is also 30 degrees), and when the final deployment angle is 60 degrees, the mobile phone 100 may determine how the closed state of S1\ S2\ S3\ S4 is in the correspondence between the stored deployment angle and the closed state of S1\ S2\ S3\ S4.
Please refer to fig. 20, which is a diagram illustrating an example of a corresponding relationship according to an embodiment of the present application. The cellular phone 100 may determine that the final deployment angle is 60 degrees based on the correspondence relationship shown in fig. 20, S1 is closed, S2 is closed, and S3 and S4 are opened. Thus, the handset 100 will close S1, S2, and open S3, S4. With continued reference to fig. 18(b), when S1 is closed, S2 is closed, and S3 and S4 are opened, the side of the first magnet facing the first column is N-level, and the side of the second magnet facing the first column is also N-level. Therefore, the S-stage of the first body rotates 30 degrees under the attraction of the first and second magnets, so that the first body is driven by the first cylinder to rotate 30 degrees, and the mobile phone 100 is finally unfolded 60 degrees.
It should be noted that, the correspondence shown in fig. 20 only lists the closed states of S1\ S2\ S3\ S4 corresponding to 4 deployment angles, and in practical applications, the correspondence may further include closed states of S1\ S2\ S3\ S4 corresponding to more deployment angles, which is not listed in this embodiment of the present application.
The second rotating shaft system in the mobile phone 100 can also drive the second body to rotate in a similar manner, and for brevity of the description, no further description is provided here.
The software architecture of the handset 100 is described below
Please refer to fig. 21, which is a schematic diagram of a software architecture of a mobile phone 100 according to an embodiment of the present application. Fig. 21 takes the android architecture as an example, and as shown in the figure, the architecture includes 4 layers, which are respectively: an application (application) layer, a framework (frame) layer, a system layer and a kernel (Linux) layer.
The application layer includes various applications such as a system interface (system UI), a WeChat, a camera, and the like.
And the framework layer comprises a display policy management module, a multimedia system (DMS) and a Window Manager Service (WMS). The display policy management module is configured to actually light a mode, such as which display screen is lighted, or what content is displayed on the display screen, and the like, according to an open/close state of the mobile phone, where specific content will be described later.
And a DMS for transmitting the lighting mode to the WMS.
And the WMS is used for displaying the interface according to the lighting mode sent by the DMS.
The system library comprises a state detection service module and a surfaceflag. The state detection service module is used for determining the opening and closing state of the mobile phone according to the sensor data and reporting the determined opening and closing state to the framework layer. The surfefringer is used for triggering the display driver to drive the display screen to display the interface.
And the inner core layer comprises a sensor driver and a display driver. The sensor driver is configured to report sensor data acquired by the sensor to the system layer, where the sensor data includes an opening angle of the mobile phone 100. The display driver is used for driving a display interface of the display screen.
The process of intelligently lighting up the screen of the mobile phone 100 will be described below with reference to the hardware architecture of the mobile phone 100 shown in fig. 3 and the software architecture of the mobile phone 100 shown in fig. 20 as examples.
(1) And the sensor driver in the kernel layer reports the sensor data acquired by the sensor to a state detection service module in the system library. Wherein the sensor data includes an angle at which the handset 100 is open.
(2) The state detection service module may report the opening angle of the mobile phone 100 to the display policy management module in the framework layer.
(3) And the display strategy management module determines the lighting mode according to the current opening angle.
As an example, the display policy management module may determine the lighting mode according to a current opening angle, for example, when the current opening angle is 60 degrees, the lighting mode is a lighting mode in which the main screen is lit and the sub-screen is extinguished.
It should be understood that the correspondence between the lighting mode and the open angle may be stored in the cellular phone 100. Please refer to fig. 22, which is an example of the corresponding relationship between the opening angle and the lighting mode provided in the embodiment of the present application. The mobile phone 100 may determine, according to fig. 22, that when the current opening angle is 60 degrees, the current opening angle is within the range of the interval [60, 120], and the corresponding lighting mode is that the main screen is lit, and the sub-screen is extinguished.
(4) After the display policy management module determines the lighting mode, the display mode may be determined.
Assuming that the current opening angle of the mobile phone 100 is 150, after the display policy management module determines that the main screen and the sub-screen are illuminated, it can also determine what interfaces are respectively displayed on the main screen and the sub-screen. For example, continuing to refer to fig. 22, where the current opening angle of the cell phone 100 is 150, it may be determined that the primary screen and the secondary screen each display the same interface. Referring to fig. 23, when the opening angle of the mobile phone 100 is 150 degrees, the display interfaces of the main screen and the sub screen are the same. If the current opening angle of the mobile phone 100 is 180 degrees, it can be seen from the corresponding relationship shown in fig. 22 that the main screen and the sub-screen are used as a large screen to display an interface, please refer to fig. 24, and the main screen and the sub-screen of the mobile phone 100 are used as a large screen to display the main interface.
(4) And after the display strategy management module determines the display mode, the display mode can be sent to the WMS through the DMS.
(5) The WMS transmits the display mode to the system UI, and the system UI adjusts parameters of the display interface based on the display mode. For example, when the display mode is the main screen is lit and the sub-screen is not lit, the system UI may adjust the parameter of the display interface to be a parameter suitable for the main screen, for example, the resolution of the main screen is 1024 × 768, and the system UI may adjust the resolution of the display interface to be 1024 × 768.
