The following describes the structure of the stylus by taking the auxiliary device being a stylus as an example.

Please refer to FIG. 4 , which is a schematic structural diagram of a stylus according to an embodiment of the present application. 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, which are used to detect the angle between the stylus and the horizontal direction, the rotation direction of the stylus, and the like.

The processing module is used for processing the data detected by the sensor module, for example, encapsulating and processing the data detected by the sensor according to the agreed communication method.

The storage module is used to store the agreed communication method between the stylus and the mobile phone 100, as well as other parameters, such as the initial angle E0 of the stylus relative to the horizontal direction, etc. The specific content will be introduced 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 following describes the process of controlling the mobile phone 100 through the stylus described in FIG. 4 :

After the stylus is connected to the mobile phone 100, the sensor module in the stylus detects sensor data such as the rotation angle and rotation direction of the stylus, and then sends the detected data to the processing module, which processes the data according to the agreed communication method. Encapsulation, 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, parses the encapsulated data according to the agreed communication method, obtains the rotation angle, rotation direction, etc., and then controls the shaft system 191 based on the rotation angle, rotation direction, etc. to change the mobile phone 100. Expand the angle.

In some embodiments, the stylus can detect data through the sensor module only when it detects that it meets certain conditions. For example, a switch can be set on the stylus, and the sensor module can only detect data when the switch is pressed. Specifically, when the processing module in the stylus detects that the switch is pressed, it can trigger and activate the sensor module to detect data.

Therefore, for the user, when the user needs to control the foldable mobile phone through the stylus, the switch on the stylus can be pressed.

In some embodiments of the present application, in order to prevent the user from erroneously triggering the switch, which may result in erroneous triggering of the sensor module detection data, the stylus may detect data through the sensor module only when it detects that the switch is long-pressed. For example, when the stylus detects that the switch is pressed for a preset time (for example, 2 seconds), the sensor module is triggered to detect data, and when the stylus detects that the switch is released (bounced up), the sensor module is turned off. That is to say, when the user controls the mobile phone 100 through the stylus, he can long press the switch on the stylus, and when he does not need to control the mobile phone 100, release the switch.

Of course, the stylus can also have other ways to control the sensor module to detect data. For example, the stylus can detect data through the sensor module when it detects that a certain switch is triggered, and when the stylus detects another switch is triggered, it can be turned off. sensor module. That is to say, the stylus is provided with two switches. When one switch is triggered, the stylus can control the mobile phone 100 , and when the other switch is triggered, the stylus stops controlling the mobile phone 100 .

It should be understood that when the user uses the stylus pen to control the mobile phone 100 for the first time, he may not know how to control the mobile phone 100 for the first time. Therefore, the mobile phone 100 or the stylus pen can give the user certain prompts. As an example, each switch on the stylus may be provided with identification information (such as a label) for indicating the function of each switch for the user to operate.

As another example, after the mobile phone 100 and the stylus are connected, the mobile phone 100 can display the interface of the process steps of controlling the mobile phone 100 through the stylus pen (the interface of the process steps can be displayed after the initial connection, or the interface of the process steps can be displayed after each connection After that, the interface of the process steps is displayed); or, after the mobile phone 100 is connected to the stylus, the stylus can output prompt information (such as voice output) to prompt the user to control the process steps of the mobile phone 100 through the stylus; After the connection between 100 and the stylus is established, a control can be displayed on the display screen of the mobile phone 100. When the control is triggered, an interface for controlling the process steps of the mobile phone 100 by the stylus pops up; For the operation steps of prompting the user to control the mobile phone 100 through the stylus pen, in practical applications, there may also be other prompting manners, which are not limited in the embodiments of the present application.

It should be noted that FIG. 4 only takes the auxiliary device being a stylus as an example. In practical applications, the auxiliary device may also be other devices, such as smart bracelets, watches, etc., which are not limited in the embodiments of the present application.

The following description takes the mobile phone 100 shown in FIG. 3 and the stylus shown in FIG. 4 as an example, and the mobile phone 100 and the stylus are connected via Bluetooth as an example for description.

It should be understood that, before the two devices perform data communication through Bluetooth, Bluetooth pairing may be performed first.

Exemplarily, the Bluetooth pairing process may include:

In the first step, the mobile phone 100 activates the Bluetooth module, and the stylus activates the Bluetooth module.

Exemplarily, the process of enabling the Bluetooth function of the mobile phone 100 may be a process in the prior art. Please refer to FIG. 5 , which is a schematic diagram of the GUI of the mobile phone 100 provided in this embodiment of the present application. When the control 501 is activated, the mobile phone 100 activates the Bluetooth function.

Exemplarily, a switch control may be set on the stylus, and when it is detected that the switch control is triggered, the stylus starts the Bluetooth module. It should be understood that the switch used on the stylus for controlling the activation of the Bluetooth module and the above-mentioned switch (the switch 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.

Please continue to refer to Fig. 5(a), after the mobile phone 100 scans the stylus device, it displays the stylus's logo 502 (the logo can be the name of the stylus, the stylus can be set at the factory, or the user Custom, which is not limited in this embodiment of the present application).

In the third step, when the mobile phone 100 detects the operation for triggering the establishment of the connection with the stylus, it connects with the stylus.

Referring to FIG. 5( a ), when the mobile phone 100 detects the operation of the control 503 triggered by the user, it establishes a connection with the stylus; or when the mobile phone 100 detects the operation of the control 503 triggered by the user, the display is shown in FIG. 5( b ). interface, that is, the mobile phone 100 pops up a prompt message 504 to prompt the user whether to establish a connection with the stylus. If the user selects yes, the mobile phone 100 establishes a Bluetooth connection with the stylus.

Of course, the process shown in FIG. 5 is only an example of the process of establishing a Bluetooth connection between the mobile phone 100 and the stylus, and other connection methods may be used in practical applications. The user may also be prompted to input the pairing code of the stylus. After the mobile phone 100 detects that the user has input the pairing code of the stylus, a connection is established with the stylus, which is not limited in the embodiment of the present application.

After the bluetooth connection is established between the stylus and the mobile phone 100, the user can control the unfolding angle of the mobile phone 100 through the stylus. It should be noted that, after the bluetooth connection is established between the stylus and the mobile phone 100, the data transmission between the stylus and the mobile phone 100 can be encapsulated by the agreed communication method.

It should be understood that the agreed communication method used when the mobile phone 100 sends data to the stylus and the agreed communication method used when the stylus sends data to the mobile phone 100 may be different, which will be introduced separately below.

The following describes the agreed communication method used when the stylus pen sends data to the mobile phone 100 .

Please refer to FIG. 6 , which is an example of the meanings of different parameter values specified in the agreed communication mode adopted when the stylus pen sends data to the mobile phone 100 . As shown in Figure 6, when the value of the parameter is 1, it represents 0 degrees; when the value of the parameter is 2, it represents 30 degrees; when the value of the parameter is 6, it represents entering the control state. When the value is 7, it means exiting the control state and so on. When the stylus sends data to the mobile phone 100, the data can be encapsulated with the meanings of different values shown in FIG. 6. For example, if the initial angle E0 of the stylus is 30 degrees, according to the table shown in FIG. 6, 30 degrees corresponds to If the value of the parameter is 2, the data sent by the stylus to the mobile phone 100 includes 2. It should be understood that, in FIG. 6 , the values of the parameters are taken as an example in decimal numbers. In fact, the parameters can also be presented in other ways, such as being represented by different characters (such as letters), or the values of the parameters can also be binary. number, which is not limited in the embodiments of the present application.

Please refer to FIG. 7( a ), which is an example of the data transmission format specified by the agreed communication method used when the stylus pen sends data to the mobile phone 100 . As shown in Figure 7(a), the data transmission format includes six fields. The parameters in the first field are used to indicate the access code; the parameters in the second field are used to indicate the header field. ); the value in the third field is used to indicate entering or exiting the screen control state; the value of each field in the fourth field to the fifth field can be used to indicate the sensor data of the stylus; for example, the fourth field The value in the first field is used to indicate the rotated angle E1 of the stylus, the value in the fifth field is used to indicate expansion or collapse, 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 between the stylus and the horizontal direction. The rotated angle E1 may be the included angle between the mobile phone and the horizontal direction after the mobile phone is rotated by a certain angle from the initial angle. Therefore, the absolute value of the difference between E1 and E0 is how much the stylus is rotated.

As an example, in the data format shown in Figure 7(a), the value of the fifth field may be determined by the stylus according to the user's operation. For example, switch 1 and switch 2 are set on the stylus. When the user wants to When the mobile phone 100 is controlled to be unfolded by the stylus, the user triggers switch 1, and the stylus detects that switch 1 is triggered, and the value of the third field is 8; when the user wants to control the folding of the mobile phone 100 by the stylus, then The user triggers switch 2, and the stylus detects that switch 2 is triggered, and the value of the third field is 9.

It should be understood that, as mentioned above, the stylus starts to control the mobile phone 100 when the stylus detects that the switch is long-pressed. Therefore, in practical applications, the stylus detects that the switch 1 is long-pressed and starts to control the mobile phone 100 to unfold. When the switch 1 is released, it stops controlling the mobile phone 100; when the stylus detects that the switch 2 is long pressed, it starts to control the folding of the mobile phone 100, and when the stylus detects that the switch 2 is released, it stops controlling the mobile phone 100. That is, the user can use different switches on the stylus to control whether the mobile phone 100 is unfolded or folded.

As another example, the value of the fifth field may also be determined by the stylus pen according to its own rotation direction. value is a positive number), the value of the fifth field of the stylus is 8, and the stylus detects that the user reduces the angle between the stylus and the horizontal plane (that is, the difference between E1 and E0 is a negative number), then the stylus determines the fifth The value of each field is 9. That is to say, in this example, the user realizes the effect of controlling the unfolding or folding of the mobile phone 100 by changing the rotation direction of the stylus.

It should be understood that in Figure 7(a), for the 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 parameters 1-4 can be is the value in the table shown in Figure 6.

It should be noted that, in the data transmission format shown in Figure 7(a), the fourth field is used to indicate the angle E1, the fifth field is used to indicate expansion or collapse, and the sixth field is used to indicate the initial angle E0 For example, in fact, it is not limited 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 expansion or collapse, and the sixth field is used to indicate the angle E1. Wait.

Therefore, when the stylus sends data to the mobile phone 100, the data can be encapsulated according to the meaning of the values shown in FIG. 6 and the data transmission format shown in FIG. 7(a), and the encapsulated data can be sent to the mobile phone 100.

The process of encapsulating data by the stylus shown in FIG. 4 is described below.

The sensor module in the stylus collects the sensor data of the stylus. It is assumed that the sensor data collected by the sensor module includes the initial angle E0 = 0 degrees between the stylus and the horizontal plane, and the included angle E1 = 30 degrees after the rotation and the horizontal plane. The sensor module can send sensor data to the processor module, and the processor module determines that the angle between the stylus and the horizontal plane increases, that is, corresponding to "expanding", and each value shown in Figure 6 is stored in the storage module in the stylus. The meaning of the representation, the processing module can query the storage module for the corresponding value when E0=0 degrees, which is 1, the corresponding value when E1=30 degrees, which is 2, and the value corresponding to "expand", which is 8. The data transmission format shown in Figure 7(a) fills in different fields with values to obtain the encapsulated data. The communication module sends the packaged data to the mobile phone 100 .

For example, please refer to FIG. 8 , which is a schematic diagram of the packaged data sent by the stylus to the mobile phone 100 . As shown in Figure 8, the encapsulated data includes six fields, of which the first field is the access code, the second field is the header, the third field is empty, and the value of the parameter in the fourth field is 2 , the value of the parameter in the fifth field is 8, and the value of the parameter in the sixth field is 1.

The following describes the process of parsing the encapsulated data after the mobile phone 100 receives the encapsulated data.

After the mobile phone 100 receives the encapsulated data, it can determine the access code, the header, and the value of each of the third to sixth fields. According to the table shown in FIG. The meaning of the value.

The access code may be used for data synchronization and identity recognition. For example, the access code may include the identity ID of the stylus. When the mobile phone 100 receives the encapsulated data sent by the stylus, it can parse the data The access code of the stylus is used to obtain the identity ID of the stylus, so as to verify whether the stylus is a device currently establishing a Bluetooth connection with the mobile phone 100 . Exemplarily, when the mobile phone 100 establishes a Bluetooth connection with the stylus, the identity ID of the stylus can be stored. After receiving the encapsulated data sent by the stylus, the mobile phone 100 parses the access code included in the data, and the learned identity ID and If the stored IDs are consistent, it is determined that the stylus is the device currently connected to the mobile phone 100 . Wherein, the identity ID may be a media access control (media access control, MAC) address, an internet protocol (internet protocol, IP) address, a device identifier (such as a product model), etc., which is not limited in this embodiment of the present application.

The header may include information indicating the bytes occupied by each of the third to sixth fields. The mobile phone 100 can accurately distinguish different fields according to the header. Exemplarily, the number of bytes occupied by each of the third field to the sixth field may be the same or different. For example, bytes 1-72 are the first field, bytes 73-127 are the second field, and bytes 128 to 129 are the third field, used to indicate entering or exiting the screen Control status, the data of the 130th-131st bytes is the fourth field, which is used to indicate the angle E1 of the stylus, and the data of the 132th-133th bytes is the fifth field, which is used to indicate expansion or folding, and the words 134-135 Section is the sixth field and is used to indicate the 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 to expand the mobile phone 100, and the mobile phone 100 can determine the absolute value of the difference between E1 (the meaning of the value of the third field) and E0 (the meaning of the value of the sixth field) , turn on the mobile phone 100 at a certain angle, and the angle may be the same as or different from the absolute value of the difference between E1 and E0.

The following describes the agreed communication method adopted when the mobile phone 100 sends data to the stylus.

Please refer to FIG. 9 , which is an example of the meaning of different values specified by the agreed communication mode adopted when the mobile phone 100 sends data to the stylus. As shown in FIG. 9 , when the value of the parameter is 0, it means that the mobile phone 100 responds successfully, and when the value of the parameter is 1, it means that the mobile phone 100 fails to respond.

Please refer to FIG. 7( b ), which is an example of the data transmission format specified by the agreed communication method used when the mobile phone 100 sends data to the stylus. 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, the second field is a header field, and the third field includes one value, which is used to indicate whether the mobile phone 100 responds successfully or fails.

It should be understood that the third field in the data transmission format shown in 7(b) is an example of a decimal number, and may actually be represented by a character or a binary number, which is not limited in the embodiments of the present application.

When the mobile phone 100 sends data to the stylus, it can encapsulate the data according to the data transmission format shown in FIG. 7( b ) and the meaning of the parameter values shown in FIG. 9 , and send the encapsulated data to the stylus.

For example, please refer to FIG. 10 , which is a schematic diagram of data sent by the mobile phone 100 to the stylus. As shown in FIG. 10 , the value of the third field in the data sent by the mobile phone 100 to the stylus is 0. It can be seen from FIG. 9 that the value of 0 represents a successful response.

The following describes the process of decapsulating the 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 can determine the access code, the header, and the values of the third field, and determine the meaning of the values in the third field according to the table shown in FIG. 9 .

The access code can be used for data synchronization and identity identification. For example, the access code can include the identity ID of the mobile phone 100. After the stylus pen receives the packaged data sent by the mobile phone 100, the stylus pen parses the data in the data. The access code can obtain the identity ID of the mobile phone 100 to verify whether the mobile phone 100 is the device currently connected with the stylus.

Among them, the header can include the number of bytes used to indicate each field. The stylus can accurately determine each byte according to the header. Taking the third field in the data shown in Figure 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 bytes 1-72 are the first field, and bytes 1-72 are the first field. Bytes 73-127 of data are the second field, and bytes 128-129 are the third field. 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 whether the mobile phone 100 responds successfully or fails.

The following describes the process of controlling the unfolding angle of the mobile phone 100 through the stylus.

Hereinafter, the first switch is set on the stylus pen as an example, and the first switch is used to enable the function of the stylus pen to control the unfolding angle of the mobile phone 100 .

Please refer to FIG. 11 , which is a schematic flowchart of a control method for a foldable electronic device according to an embodiment of the present application. This method can be applied to auxiliary devices, such as the stylus mentioned above. As shown in Figure 11, the flow of the method includes:

S1101: The stylus pen detects that a user inputs a first operation.

As can be seen from the foregoing, a first switch may be provided on the stylus, and when the user wants to control the unfolding angle of the mobile phone 100 through the stylus, the first switch may be pressed. Therefore, the first operation may be an operation in which the first switch is pressed.

S1102: In response to the first operation, the stylus sends a first instruction to the mobile phone 100, where the first instruction is used to instruct 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.

Exemplarily, the stylus pen sends the first instruction to the mobile phone 100 after detecting that the first switch is continuously pressed for a preset period of time.

Exemplarily, the stylus can use the data transmission format shown in FIG. 7( a ) to encapsulate the data to be sent, and encapsulate it into a first instruction. Please refer to FIG. 12 , which is a schematic diagram of the first instruction. As shown in FIG. 12 , the value of the third field in the first instruction is 6, that is, it is used to indicate entering the screen control state, and the fourth to sixth fields may be empty.

S1103: The mobile phone 100 enters the screen control state.

Exemplarily, when the mobile phone 100 enters the screen control state, preparations can be made for changing the deployment angle, such as recording the initial state of the mobile phone 100. The initial state includes which body of the mobile phone 100 is currently in contact with the horizontal plane, and the current deployment angle (hereinafter referred to as the initial deployment angle), etc. For another example, powering on the shaft system 191, etc., the specific process will be described later.

After the mobile phone 100 records the initial state (such as the current deployment angle), the deployment angle is adjusted in the initial state. For example, the current deployment angle is 30 degrees, and the mobile phone 100 receives an instruction, the angle information carried in the instruction is 30 degrees, and the instruction indicates When the mobile phone 100 is unfolded, the mobile phone 100 is further increased by 30 degrees on the basis of the current unfolding angle, that is, after adjustment, the unfolding angle is 60 degrees.

S1104: The mobile phone 100 feeds back a second instruction to the stylus, where the second instruction is used to indicate that the mobile phone 100 responds successfully.

The mobile phone 100 can encapsulate the data to be sent according to the data transmission format shown in FIG. 7( b ), obtain a second instruction, and send the second instruction to the stylus.

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 mobile phone 100 responds successfully.

It should be understood that the response success 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, which is not limited in this embodiment of the present application.

S1105: The stylus detects that it is rotated by the first angle.

The stylus is provided with a sensor module, including a gyroscope or an angular velocity sensor, which can be used to detect the rotation angle of the stylus.

As an example, when the stylus pen detects that the first switch is pressed, the sensor module detects the included angle between the stylus pen and the horizontal plane, that is, the initial angle E0, and records the initial angle E0. The sensor module can detect the angle between the stylus and the horizontal plane in real time or periodically. When the stylus is rotated under the operation of the user, the sensor module can detect the angle E1 after the stylus is rotated (the angle between the stylus and the horizontal direction after the stylus is rotated). The first angle may be the difference between E1 and E0.

S1106: The stylus 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 instruct the mobile phone 100 to be folded or unfolded.

As can be seen from the foregoing, the stylus 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 a positive number, unfold the mobile phone 10, and when the difference between E1 and E0 is a negative number, fold the mobile phone 100. Phone 100. The stylus can encapsulate the data to be sent by using the agreed communication method to obtain the third instruction.

For example, please refer to FIG. 14 , which is a schematic diagram of the third instruction. As shown in Figure 14, the value of the third field in the third instruction is empty, the value of the fourth field represents the rotated angle E1, the value of the fifth field represents expansion, and the value of the sixth field represents the initial Angle E0. In the example shown in FIG. 14 , the third instruction includes the initial angle E0 and the rotated angle E1 , and the absolute value of the difference between the two is the angle by which the stylus is rotated.

S1107: The mobile phone 100 controls the deployment angle of the mobile phone 100 to be the second angle based on the third instruction.

After receiving the third instruction, the mobile phone 100 can parse the third instruction, determine the absolute value of the difference between E1 and E0, obtain the rotation angle of the stylus, and determine the unfolding or folding indicated in the third instruction.

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 contact between the first body and the horizontal plane, and the initial deployment angle of the mobile phone 100 is 30 degrees, if the third command instructs to unfold the mobile phone 100 and instructs the stylus to rotate 30 degrees, then The mobile phone 100 controls the rotating shaft system 191 to drive the second body to rotate by 30 degrees, so the final unfolding angle of the mobile phone 100 is 60 degrees. If the third command instructs to fold the mobile phone 100 and the rotation angle of the stylus is 30 degrees, the mobile phone 100 controls the hinge system 191 to drive the second body to rotate by 30 degrees. The spread angle is 0 degrees.

As another example, the mobile phone 100 may calculate another angle based on the rotation angle of the stylus, 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 contact between the first body and the horizontal plane, and the initial deployment angle of the mobile phone 100 being 30 degrees, the third instruction instructs the rotation angle of the stylus to be 30 degrees, and the third instruction instructs the deployment For the mobile phone 100, the mobile phone 100 calculates another angle value based on 30 degrees, and controls the rotating shaft system 191 to drive the second body to rotate by the calculated angle. Therefore, the final deployment angle of the mobile phone 100 is the sum of the initial deployment angle and the calculated angle.

Exemplarily, the mobile phone 100 can calculate the rotation angle according to the following formula (1):

Wherein, E1 is the rotation angle of the stylus pen, E0 is the initial angle of the stylus pen, V0 is a preset angle, and the preset angle may be the maximum angle that the mobile phone 100 can rotate, such as V0=180 degrees.

The mobile phone 100 can calculate the rotation angle V according to the values of E1, E0 and the value of V0 carried in the third instruction. Therefore, the angle by which the mobile phone 100 is rotated is V, not (E1-E0).

S1108: The mobile phone 100 sends a fourth instruction to the stylus, where the fourth instruction is used to indicate that the response is successful.

Exemplarily, after the mobile phone 100 rotates the angle successfully, a fourth instruction may be sent to the stylus to indicate that the rotation is successful. Of course, after the rotation of the mobile phone 100 fails (for example, the rotating shaft system 191 works abnormally, cannot be powered on, etc., so that the deployment angle does not change, or the mobile phone 100 has been deployed to the maximum angle), the stylus can also be sent to the stylus for the rotation failure. instruction.

As an example, after the stylus pen receives an instruction for indicating that the mobile phone 100 fails to rotate, it can output prompt information to prompt the user that the mobile phone 100 fails to rotate. Of course, after the mobile phone 100 fails to rotate, the mobile phone 100 can also output prompt information by itself to prompt the user that the rotation fails.

In other embodiments, the mobile phone 100 may also not need to send the fourth instruction to the stylus, which is not limited in the embodiments of the present application.

S1009: The stylus detects the second operation.

Exemplarily, the second operation may be an operation in which the first switch on the stylus is released.

S1010: In response to the second operation, the stylus sends a fifth instruction to the mobile phone 100, where the fifth instruction is used to instruct the mobile phone 100 to exit the screen control state.

Exemplarily, the fifth instruction is similar to the foregoing first instruction, and details are not repeated here.

S1111: The mobile phone 100 exits the screen control state.

Exemplarily, when the mobile phone 100 exits the screen control state, the hinge system 191 may be turned off, for example, the hinge system 191 may be powered off; or, the recorded data related to the initial state may be deleted.

The control flow of the stylus pen to the mobile phone 100 is described below by way of example.

Example 1:

Please refer to FIG. 15 , which is a schematic flowchart of a stylus pen controlling the unfolding angle of the mobile phone 100 . As shown in Figure 15, the process includes:

The first process: the stylus is placed horizontally, the mobile phone 100 is closed (the deployment angle is 0 degrees), and the second body is in contact with the horizontal plane. After the stylus detects that the switch K1 is long pressed, it sends a first command to the mobile phone 100. The first field in the first command includes the access code, the second field includes the header, and the value in the third field is 6, which is used for Indicates that the mobile phone 100 enters the screen control state, and other fields are empty. The mobile phone 100 receives the first instruction, enters the screen control state, and records the initial state, where the initial state includes that the initial deployment angle is 0 degrees.

The second process: the stylus is rotated 30 degrees by the user, and the stylus sends a second command to the mobile phone 100. The first field of the second command includes the access code, the second field includes the header, the third field is empty, and the third field is empty. The value of the four fields is 2, the value of the fifth field is 8, and the value of the sixth field is 1. After the mobile phone 100 receives the second command, it analyzes the meaning of each value according to the meaning of the values shown in FIG. 6 , and determines that it needs to be rotated 60 degrees according to the above formula (1), that is, the mobile phone 100 controls the rotating shaft system 191 to drive the first value. A body is rotated 60 degrees, and the final deployment angle is 60 degrees.

In the third process, the stylus is continuously rotated by the user by 30 degrees, and the stylus sends a third command to the mobile phone 100. The value of the fourth field in the third command is 3, the fifth field is 8, and the sixth field is 2. After the mobile phone 100 receives the third instruction, it analyzes the meaning of each value according to the meaning of the values shown in FIG. 6, and according to the above formula (1), it is determined that it needs to be rotated by 60 degrees, then the mobile phone 100 controls the rotating shaft system 191 to drive the first value. A body continues to rotate 60 degrees, and the final deployment angle is 120 degrees.

The fourth process: the stylus is continuously rotated by the user by 30 degrees, and the stylus sends a fourth instruction to the mobile phone 100. In the fourth instruction, the value of the fourth field is 4, the value of the fifth field is 8, and the value of the sixth field The value is 3. After the mobile phone 100 receives the fourth instruction, it analyzes the meaning of each value according to the meaning of the values shown in FIG. 6, and according to the aforementioned formula (1), it is determined that it needs to continue to rotate 60 degrees, then the mobile phone controls the rotating shaft system 191 to drive the first value. A body continues to rotate 60 degrees, and the final deployment angle is 180 degrees.

Fifth process: after detecting that the switch K1 is released, the stylus pen sends a fifth instruction to the mobile phone 100, and the value of the 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 , during the process of opening the mobile phone 100 from 0 degrees to 180 degrees, the screen can be automatically turned on.

As an example, the mobile phone 100 may determine which screen to light up according to the current deployment angle. For example, if the current deployment angle is within the first angle range, the mobile phone 100 lights up the main screen; if the current deployment angle is within the second angle range, the mobile phone 100 lights up the secondary screen, and the minimum value of the second angle range is greater than the second angle range. The maximum value of an angular range.

Exemplarily, the main screen and the secondary screen on the mobile phone 100 may be set by the user; alternatively, the main screen and the secondary screen on the mobile phone 100 may be set by default when the mobile phone 100 leaves the factory; or, the main screen on the mobile phone 100 may be a body that rotates The upper screen, the secondary screen is the screen on the main body that has not rotated; or, the mobile phone 100 detects which screen the user is looking at (for example, if the camera on the first main body detects a human face, the user is looking at the screen on the first main body), Which screen is the home screen.

Exemplarily, continuing to take FIG. 15 as an example, when the mobile phone 100 detects that the unfolding angle is 60 degrees, it can light up the main screen, assuming that the main screen is the screen of the rotating body (ie the screen on the first body). After the mobile phone 100 lights up the main screen, the lock screen interface can be displayed; or the switch K1 on the stylus is provided with a fingerprint sensor, which can be used to collect the user's fingerprint and send the collected fingerprint to the mobile phone 100, and the mobile phone 100 lights up the main screen After that, it can be verified whether the fingerprint is consistent with the stored fingerprint. If they are consistent, the device is unlocked, that is, the main interface is displayed after the main screen is lit. Exemplarily, after the mobile phone 100 lights up the home screen, it can send a prompt message to the stylus, and the prompt message (such as a voice prompt) is used to prompt the user to enter a fingerprint on the side of the stylus. Sent to mobile phone 100. Exemplarily, the fingerprint sensor on the stylus can be integrated on 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 through the stylus, the fingerprint sensor on the switch K1 collects the user’s fingerprint, Then, the collected fingerprints are sent to the mobile phone 100 .

Exemplarily, after the main screen is turned on, the lock screen interface can be displayed first, and after the fingerprint verification is successful, the main interface is entered, or the mobile phone 100 can verify the fingerprint first, and after the verification is successful, the main interface can be directly displayed without displaying the lock screen interface. . In the second process, the secondary screen can be in an off-screen state.

In the third process, the mobile phone 100 detects that it is opened by 120 degrees, and can light up the secondary screen. After the secondary screen is lit, it can display the same content as the main screen, that is, the display interfaces of the secondary screen and the main screen are the same. When the mobile phone 100 detects that it is opened by 180 degrees, the main screen and the secondary screen act 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 introduced later.

Example 2:

Please refer to FIG. 16 , which is a schematic flowchart of a stylus pen controlling the unfolding angle of the mobile phone 100 . Comparing the process shown in FIG. 16 with the process shown in FIG. 15, it can be seen that in the process shown in FIG. 16, the stylus is gradually changed from the vertical placement state to the horizontal placement state, so the deployment angle of the mobile phone 100 is adjusted from 180 degrees is 0 degrees.

It should be noted that, in the process shown in FIG. 16 , during the process of the mobile phone 100 from 180 degrees to 0 degrees, the screen can be gradually turned off.

Exemplarily, 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 reducing the deployment angle from 180 degrees to 120 degrees (the second process), the main screen and the secondary screen can display the same interface as two separate display screens. In the process of reducing the deployment angle from 120 degrees to 60 degrees (the third process), the secondary screen can be turned off, and when the deployment angle is reduced from 60 degrees to 0 degrees, the main screen can be turned off.

The following describes the process of controlling the unfolding angle by the rotating shaft system 191 of the mobile phone 100 .

Please refer to FIG. 17, which is a schematic diagram of the rotating shaft system 191. As shown in FIG. 17, the rotating shaft system 191 includes a first rotating shaft system and a second rotating shaft system, wherein the first rotating shaft system can be used to drive the first body to rotate. The second shaft system can 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, and the initial state includes which body on the mobile phone 100 is in contact with the desktop. The first body rotates; if the second body is in contact with the desktop, the mobile phone 100 controls the second shaft system to drive the second body to rotate.

In some embodiments, the mobile phone 100 can determine which body is in contact with the object through the pressure sensor. For example, if a body of the mobile phone 100 is in contact with the desktop, a pressure sensor on the body generates a pressure signal, the mobile phone 100 can determine that the body is in contact with the desktop, and control the rotation of the other body through the shaft system corresponding to the other body.

In other embodiments, the mobile phone 100 can also determine which body does not need to rotate through the ambient light sensor. For example, both the first body and the second body are provided with ambient light sensors. If the ambient light sensor on the first body When it is detected that the ambient light is weak, the mobile phone 100 can 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 can also determine which body does not need to be rotated in other ways. For example, if the mobile phone 100 determines that the contact area between the first body and the user's hand is larger, the first body does not need to be rotated, and the first body does not need to be rotated. The two bodies rotate.

Taking the first shaft system as an example, please refer to Fig. 18(a), the first shaft system includes a first cylinder and a second cylinder, and the second cylinder may be hollow and 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 connecting body drives the first body to rotate.

The first cylinder may have magnetism, and four magnets are arranged outside the first cylinder and inside the second cylinder to drive the first cylinder to rotate. It should be understood that the four magnets may be metal bodies with wires wound around their outer surfaces, and when the wires are energized, the metal bodies generate magnetism.

Exemplarily, please continue to refer to FIG. 18( b ), the first cylinder itself has magnetism, and half of the first cylinder is S-level, and the other half is N-level. The 4 metal bodies are surrounded by wires, and the wires around the periphery of each metal body are connected to the power supply. When the wire around a metal body is energized, the metal body generates magnetism, which can attract or repel the first cylinder, which in turn leads to the first cylinder. A cylinder rotates. Please continue to refer to Fig. 18(b), when the switch S3 is closed, the side of the third magnet facing the first cylinder is in the S-level, attracting the N-level of the first cylinder.

Please refer to FIG. 19 , which are schematic diagrams of two forms of the mobile phone 100 . When the second body is in contact with the desktop, the cross section of the first shaft system is shown in Figure 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. Among them, the positions of the four magnets do not change. For example, when the angle between the first body and the second body is 0, the S-level of the first cylinder is facing the first magnet, because the side of the first magnet facing the first cylinder is the N-level at this time. . When the angle between the first body and the second body is 90 degrees, the S-level of the first cylinder is facing the second magnet, because at this time the side of the second magnet facing the first cylinder is the N-level .

When the first body is in contact with the desktop, the cross section of the second shaft system is shown in Figure 19(b), and the first cylinder in the second 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. Among them, the positions of the four magnets do not change. For example, when the angle between the first body and the second body is 0, the S-level of the first cylinder is facing the first magnet, because the side of the first magnet facing the first cylinder is the N-level at this time. . When the angle between the first body and the second body is 90 degrees, the S-level of the first cylinder is facing the second magnet, because at this time the side of the second magnet facing the first cylinder is the N-level .

It should be understood that, in order to conveniently control a certain metal body to generate magnetism, a switch may be provided between the wires on the periphery of each metal body in the first rotating shaft system or the second rotating shaft system and the power source.

The following description will be given by taking the second body of the mobile phone 100 in contact with the desktop and driving the first body to rotate through the first rotating shaft system as an example.

When the mobile phone 100 enters the screen control state, the initial state is recorded. The initial state may include the initial expansion angle. The mobile phone 100 receives the control command sent by the stylus. Assuming that the angle information indicated by the control command is 30 degrees, the mobile phone 100 needs to control the first The body rotates 30 degrees, that is to say, the final deployment angle is 60 degrees (assuming the initial deployment angle is also 30 degrees), the mobile phone 100 can determine the corresponding relationship between the stored deployment angle and the closed state of S1\S2\S3\S4 When the final deployment angle is 60 degrees, what is the closed state of S1\S2\S3\S4.

Please refer to FIG. 20 , which is an example of a corresponding relationship provided by this embodiment of the present application. Based on the corresponding relationship shown in FIG. 20 , the mobile phone 100 can determine that when the final deployment angle is 60 degrees, S1 is closed, S2 is closed, and S3 and S4 are open. Therefore, the handset 100 will close S1, S2 and open S3, S4. Please continue to refer to Figure 18(b), when S1 is closed, S2 is closed, and S3 and S4 are open, the side of the first magnet opposite to the first cylinder is N-level, and the second magnet is connected to the first cylinder. The opposite side is also rated N. Therefore, the S stage on the first body rotates 30 degrees under the attractive force of the first magnet and the second magnet. In this case, the first cylinder drives the first body to rotate 30 degrees, and the mobile phone 100 is finally unfolded by 60 degrees.

It should be noted that the correspondence shown in Figure 20 only lists the closed states of S1\S2\S3\S4 corresponding to the four deployment angles. The closed states of S2\S3\S4 and the embodiments of the present application are not listed one by one.

The second rotating shaft system in the mobile phone 100 can also drive the second body to rotate in a similar manner, which is not repeated here for the sake of brevity of the description.

The software architecture of the mobile phone 100 is described below

Please refer to FIG. 21 , which is a schematic diagram of the software architecture of the mobile phone 100 according to the embodiment of the present application. Figure 21 takes the Android architecture as an example. As shown in the figure, the architecture includes four layers, namely: an application layer, a framework layer, a system layer, and a kernel (Linux) layer.

Among them, the application layer includes various applications, such as system UI, WeChat, camera, and so on.

The framework layer includes a display strategy management module, a multimedia system (demand multimedia system, DMS), and a window management service (window manager service, WMS). Among them, the display strategy management module is used to determine the lighting mode according to the opening and closing state of the mobile phone, such as which display screen is lit, or what content is displayed on the display screen, etc. The specific content will be introduced later.

DMS, used to send lighting pattern to WMS.

WMS, used to display the interface according to the lighting mode sent by DMS.

The system library includes the state detection service module and surfaceflinger. Among them, the state detection service module is used to determine the opening and closing state of the mobile phone according to the sensor data, and report the determined opening and closing state to the framework layer. Surfaceflinger is used to trigger the display driver to drive the display interface.

Kernel layer, including sensor driver and display driver. The sensor driver is used to report the sensor data collected by the sensor to the system layer, and the sensor data includes the opening angle of the mobile phone 100 . The display driver is used to drive the display interface of the display screen.

Taking 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 an example, the following describes the process of intelligently lighting the screen of the mobile phone 100 .

(1) The sensor driver in the kernel layer reports the sensor data collected by the sensor to the state detection service module in the system library. The sensor data includes the opening angle of the mobile phone 100 .

(2) The state detection service module can report the opening angle of the mobile phone 100 to the display policy management module in the framework layer.

(3) The display strategy management module determines the lighting mode according to the current opening angle.

As an example, the display strategy management module may determine the lighting mode according to the 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 turned on and the secondary screen is turned off.

It should be understood that the corresponding relationship between the lighting mode and the opening angle may be stored in the mobile phone 100 . Please refer to FIG. 22 , which is an example of the correspondence between the opening angle and the lighting mode provided by the embodiment of the present application. The mobile phone 100 can be determined according to FIG. 22 , when the current opening angle is 60 degrees, which is in the range of [60, 120], the corresponding lighting mode is to turn on the main screen and turn off the secondary screen.

(4) After the display strategy management module determines the lighting mode, it can also determine the display mode.

Assuming that the current opening angle of the mobile phone 100 is 150 degrees, after the display policy management module determines that the main screen and the secondary screen are lit, it can also determine which interface is displayed on the main screen and the secondary screen respectively. 22, the current opening angle of the mobile phone 100 is 150 degrees, and it can be determined that the main screen and the secondary screen display the same interface respectively. 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 secondary screen are used as a large screen to display an interface, as shown in FIG. 24, the main screen and the secondary screen of the mobile phone 100 are used as a large screen screen to display the main interface.

(4) 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 sends the display mode to the system UI, and the system UI adjusts the parameters of the display interface based on the display mode. For example, when the display mode is on the main screen and the secondary screen is off, the system UI can adjust the parameters of the display interface to the parameters suitable for the main screen. For example, the resolution of the main screen is 1024*768, then the system UI can adjust the resolution of the display interface to 1024 *768.

For another example, if the display mode is on both the main screen and the secondary screen, and the main screen and the secondary screen display the same interface (see Figure 22), the system UI can adjust the resolution of the display interface to 1024*768, and the main screen display, and adjust the resolution of the other display interface to 2400*1200, and display it through the secondary screen.

It should be noted that the main screen and the secondary screen involved in FIGS. 22 , 23 and 24 can be set by default when the mobile phone 100 leaves the factory, or they can be customized by the user in the process of using the mobile phone 100 , or they can be The mobile phone 100 automatically recognizes that it is determined. For example, taking FIG. 1 as an example, when the mobile phone 100 detects that the current second body is in contact with the desktop, it determines that the display screen corresponding to the second body is the secondary screen, and the display screen corresponding to the first body is the main screen; when the mobile phone 100 detects that the current second body is in contact with the desktop When a main body is in contact with the desktop, it is determined that the display screen corresponding to the first main body is the main screen, and the display screen corresponding to the second main body is the secondary screen.
