In some embodiments, the pressure sensor 180A may be provided on the display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors and so on. The capacitive pressure sensor may include at least two parallel plates with conductive material. When a force is applied to the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the intensity of the pressure according to the change in capacitance. When a touch operation acts on the display screen 194, the electronic device 100 detects the intensity of the touch operation according to the pressure sensor 180A. The electronic device 100 may also calculate the touched position according to the detection signal of the pressure sensor 180A. In some embodiments, touch operations that act on the same touch location but have different touch operation strengths may correspond to different operation instructions. For example: when a touch operation whose intensity of the touch operation is less than the first pressure threshold is applied to the short message application icon, an instruction to view the short message is executed. When a touch operation with a touch operation intensity greater than or equal to the first pressure threshold acts on the short message application icon, an instruction to create a new short message is executed.

The ambient light sensor 180L is used to sense the brightness of the ambient light. The electronic device 100 can adaptively adjust the brightness of the display screen 194 according to the perceived brightness of the ambient light. The ambient light sensor 180L can also be used to automatically adjust the white balance when taking pictures.

For example, when the temperature reported by the temperature sensor 180J exceeds a threshold value, the electronic device 100 executes to reduce the performance of the processor located near the temperature sensor 180J, so as to reduce power consumption and implement thermal protection. In other embodiments, when the temperature is lower than another threshold, the electronic device 100 heats the battery 142 to avoid abnormal shutdown of the electronic device 100 due to low temperature. In some other embodiments, when the temperature is lower than another threshold, the electronic device 100 boosts the output voltage of the battery 142 to avoid abnormal shutdown caused by low temperature.

Touch sensor 180K, also called "touch device". The touch sensor 180K may be disposed on the display screen 194, and the touch screen is composed of the touch sensor 180K and the display screen 194, which is also called a “touch screen”. The touch sensor 180K is used to detect touch operations acting on or near it. The touch sensor can pass the detected touch operation to the application processor to determine the type of touch event. The visual output related to the touch operation can be provided through the display screen 194.

The parallel sensor 180N is used to detect a plane parallel to the electronic device. The parallel sensor 180N may include a transmitter and a receiver. The transmitter is used to emit light or sound waves; the receiver is used to receive the reflected light or sound waves. For the convenience of description, the light waves or sound waves emitted by the transmitter are referred to as "transmitted waves"; the light waves or sound waves reflected by objects are referred to as "reflected waves".

When the plane to be detected is parallel to the electronic device, the transmitted wave enters the plane perpendicularly, and the reflected wave returns to the parallel sensor 180N along the original path (that is, the path of the reflected wave is the same as the path of the transmitted wave, but the direction is opposite). The receiver receives. Conversely, when the plane to be detected is not parallel to the electronic device, the emitted wave is incident on the plane at a certain angle, and the reflected wave returns with a path deviating from the original path. At this time, the path of the reflected wave deviates from the parallel sensor 180N, and the reflected wave received by the receiver is reduced, which is less than the reflected wave received by the receiver when it is parallel. It can be seen that, by detecting the reflected wave received by the receiver, the electronic device can detect a plane parallel to the electronic device. If the reflected wave received by the receiver is greater than the predetermined first threshold, it is equivalent to the electronic device determining that the plane is parallel to the electronic device; conversely, if the reflected wave received by the receiver is less than the predetermined second threshold, it is equivalent to the electronic device determining the plane The plane is not parallel to the electronic device. It should be noted that the first threshold may be the same as or different from the second threshold. Or, if the reflected wave received by the receiver is the maximum value, it is equivalent to the electronic device determining that the plane is parallel to the electronic device; conversely, if the reflected wave received by the receiver is less than the above maximum value, it is equivalent to the electronic device determining that the plane is parallel to the electronic device Not parallel.

It should be noted that the electronic device may not have a separate parallel sensor 180N, and the proximity sensor 180G of the electronic device may serve as the parallel sensor.

Acting on touch operations in different areas of the display screen 194, the motor 191 can also correspond to different vibration feedback effects. Different application scenarios (for example: time reminding, receiving information, alarm clock, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

The software system of the electronic device 100 may adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. The embodiment of the present application takes a layered Android system as an example to illustrate the software structure of the electronic device 100.

FIG. 2 is a block diagram of the software structure of the electronic device 100 according to an embodiment of the present application.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Communication between layers through software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, the application layer, the application framework layer, the Android runtime and system library, and the kernel layer.

The application layer can include a series of application packages.

As shown in Figure 2, the application package can include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

The application framework layer provides application programming interfaces (application programming interface, API) and programming frameworks for applications in the application layer. The application framework layer includes some predefined functions.

As shown in Figure 2, the application framework layer can include a window manager, a content provider, a view system, a phone manager, a resource manager, and a notification manager.

The window manager is used to manage window programs. The window manager can obtain the size of the display, determine whether there is a status bar, lock the screen, take a screenshot, etc.

The content provider is used to store and retrieve data and make these data accessible to applications. The data may include video, image, audio, phone calls made and received, browsing history and bookmarks, phone book, etc.

The view system includes visual controls, such as controls that display text and controls that display pictures. The view system can be used to build applications. The display interface can be composed of one or more views. For example, a display interface that includes a short message notification icon may include a view that displays text and a view that displays pictures.

The phone manager is used to provide the communication function of the electronic device 100. For example, the management of the call status (including connecting, hanging up, etc.).

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, etc.

The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and it can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify the download completion, message reminder, etc. The notification manager can also be a notification that appears in the status bar at the top of the system in the form of a chart or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, text messages are prompted in the status bar, prompt sounds, electronic devices vibrate, and indicator lights flash.

Android Runtime includes core libraries and virtual machines. Android runtime is responsible for the scheduling and management of the Android system.

The core library consists of two parts: one part is the function functions that the java language needs to call, and the other part is the core library of Android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes the java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

The system library can include multiple functional modules. For example: surface manager (surface manager), media library (Media Libraries), three-dimensional graphics processing library (for example: OpenGL ES), 2D graphics engine (for example: SGL), etc.

The surface manager is used to manage the display subsystem and provides a combination of 2D and 3D layers for multiple applications.

The media library supports playback and recording of a variety of commonly used audio and video formats, as well as still image files. The media library can support multiple audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The 3D graphics processing library is used to realize 3D graphics drawing, image rendering, synthesis, and layer processing.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, and sensor driver.

In the following, the workflow of the software and hardware of the electronic device 100 will be exemplified in conjunction with capturing a photo scene.

When the touch sensor 180K receives a touch operation, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes touch operations into original input events (including touch coordinates, time stamps of touch operations, etc.). The original input events are stored in the kernel layer. The application framework layer obtains the original input event from the kernel layer, and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation, and the control corresponding to the click operation is the control of the camera application icon as an example, the camera application calls the interface of the application framework layer to start the camera application, and then starts the camera driver by calling the kernel layer. The camera 193 captures still images or videos.

In the embodiment of the present application, the display screen 194 may be deformable. The deformable display screen 194 may be referred to as a "flexible screen." Deformation means that the radius of curvature of a part of the display screen 194 of the electronic device is smaller than the reference value. For example, the deformation may be any one of folding, bending, twisting, curling, and combinations thereof. Among them, folding and bending can be distinguished according to the degree of deformation. For example, if the display screen 194 is bent at an angle greater than a predetermined value, it can be defined as "folded." In contrast to this, if the display screen 194 is bent at an angle equal to or smaller than the predetermined value, it can be defined as "bending". For the convenience of description, this bending and folding is referred to as "bending" below. In the following embodiments, the structure of the electronic device related to the deformation of the display screen 194 will be described in more detail with reference to the drawings.

Illustratively, the electronic device is a double-folding mobile phone as an example for description. FIG. 3 is a schematic structural diagram of an electronic device 100 provided by an embodiment of the application. As shown in FIG. 3, the electronic device 100 includes: a connection unit 301, a main body 302, a main body 303 and a display screen 194. The connecting unit 301 is used to connect the main body 302 and the main body 303. The size of the main body 302 and the main body 303 may be the same or different. The thickness of the main body 302 and the main body 303 may be the same. The display screen 194 covers the connection unit 301, the main body 302 and the main body 303. The display screen 194 can be bent inward or outward through the connecting unit to change the angle between the main bodies. 4(a) and 4(b), the angle ɑ between the main body 302 and the main body 303 is the angle between the main body 302 and the main body 303 (ie, an angle less than 180 degrees).

Exemplarily, as shown in FIGS. 5(a) and 5(b), the electronic device is in a flat state, which may also be referred to as an unfolded state. At this time, the main body 302 and the main body 303 are located on the same horizontal plane. The angle ɑ between the main body 302 and the main body 303 is 180 degrees. As the user bends the display screen 194, the electronic device may change from a flat state to a folded state, or from a folded state to a flat state. The folded state may include a first folded state and/or a second folded state.

As shown in FIG. 5(c) and FIG. 5(d), the electronic device is in the first folded state. At this time, the main body 302 and the main body 303 are parallel to each other, the display screen 194 faces the outside of the electronic device, and the angle ɑ between the main body 302 and the main body 303 is 0 degree. When the display screen 194 is bent outward from the flat state to the first folded state, the angle between the main body 302 and the main body 303 gradually decreases, and the angle between the main body 302 and the main body 303 decreases from 180 degrees to 0 degrees. Folding the display screen 194 inward from the first folded state to the flat state, the angle between the main body 302 and the main body 303 gradually increases, and the angle between the main body 302 and the main body 303 increases from 0 degrees to 180 degrees.

As shown in Figure 5(e) and Figure 5(f), the electronic device is in the second folded state. At this time, the main body 302 and the main body 303 are parallel to each other, the display screen 194 faces the inside of the electronic device, and the angle ɑ between the main body 302 and the main body 303 is 0 degree. When the display screen 194 is bent inward from the flat state to the second folded state, the angle between the main body 302 and the main body 303 gradually decreases, and the angle between the main body 302 and the main body 303 gradually decreases from 180 degrees to 0 degrees. When the display screen 194 is bent outward from the second folded state to a flat state, the angle between the main body 302 and the main body 303 gradually increases, and the angle between the main body 302 and the main body 303 increases from 0 degrees to 180 degrees.

It should be noted that, in FIG. 5, a folding mobile phone that supports 180-degree bending is taken as an example for illustration. Understandably, the electronic device can also support 360 degrees. At this time, the user can bend the display screen 194 inwardly by 360 degrees from the first folded state to the second folded state, or bend outwardly by 360 degrees from the second folded state to the first folded state.

The electronic device 100 can recognize the angle between the main bodies (for example, the angle between the main body 302 and the main body 303). For example, the electronic device 100 may recognize the angle between the subjects through the acceleration sensor 180E. Exemplarily, the electronic device 100 includes a plurality of acceleration sensors 180E, which are respectively disposed in each main body. The electronic device can detect the acceleration of each axis (e.g., x-axis, y-axis, and z-axis) of each main body through the acceleration sensor provided in each main body (eg, main body 302, main body 303), and according to the detected acceleration of each axis Large and small electronic devices can determine the posture of each subject (e.g., the posture of the subject 302 and the posture of the subject 303), and then determine the angle between the subject according to the posture of any subject and the other subject (e.g., according to the posture of the subject 302 and the The posture of the main body 303 determines the angle between the main body 302 and the main body 303).

Taking the double-folding mobile phone described in FIG. 3 as an example, the electronic device 100 may include a first acceleration sensor and a second acceleration sensor. Among them, the first acceleration sensor is disposed on the main body 302; the second acceleration sensor is disposed on the main body 303. The first acceleration sensor detects the acceleration of the main body 302 on the x1, y1, and z1 axes, respectively. Exemplarily, the x1, y1 and z1 axes are shown in Figure 6(a), the x1 axis is the horizontal direction of the plane where the main body 302 is located; the y1 axis is the direction perpendicular to the x1 axis in the plane where the main body 302 is located; the z1 axis is the direction perpendicular to the main body 302 The direction perpendicular to the plane where 302 is located. The second acceleration sensor detects the acceleration of the main body 303 on the x2, y2, and z2 axes, respectively.

The electronic device 100 may determine the posture of each body based on the acceleration of each axis detected by the acceleration sensor provided in each body. For example, the electronic device 100 may determine the posture of the main body 302 according to the acceleration of the x1, y1 and z1 axes, and determine the posture of the main body 303 according to the acceleration of the x2, y2 and z2 axes. Exemplarily, the electronic device 100 may calculate the angle θ _z1 between the z1 axis and the horizontal direction according to the accelerations of the x1, y1 and z1 axes, and calculate the angle θ between the z2 axis and the horizontal direction according to the accelerations of the x2, y2 and z2 axes. _z2 . The calculation formula is shown in formula 1:

Where a _z is the acceleration of the x-axis, a _y is the acceleration of the y-axis, and a _z is the acceleration of the z-axis. θ _z is the angle between the z axis and the horizontal direction.

The electronic device 100 can determine the angle between the two main bodies according to the postures of any one main body and the other main body. For example, the electronic device 100 may determine the angle between the main body 302 and the main body 303 according to the postures of the main body 302 and the main body 303. It is understandable that, as shown in Figure 6(b), the electronic device can calculate the angle between the main body 302 and the main body 303 according to the angle θ _{z1 between the z1} axis and the horizontal direction, and the angle θ _z2 between the z2 axis and the horizontal direction. ɑ, its calculation formula is shown in formula 2:

ɑ=180+θ _Z1 -θ _Z2 (Equation 2)

It should be noted that, in the embodiment of the present application, the angle between the main body 302 and the main body 303 is calculated based on the angle between the z1 axis and the horizontal direction and the angle between the z2 axis and the horizontal direction as an example. The method of calculating the angle between the main body 302 and the main body 303 is not limited to this. For example, the electronic device 100 can calculate the angle between the main body 302 and the main body 303 according to the included angle θ _x1 between the x1 axis and the horizontal direction, and the included angle θ _x2 between the x2 axis and the horizontal direction, and the calculation formula is as shown in Equation 3:

ɑ=180-(θ _x1 -θ _x2 ) (Equation 3)

The electronic device 100 may calculate the angle θ _x1 between the x1 axis and the horizontal direction according to the accelerations of the x1, y1 and z1 axes, and obtain the angle θ _{x2 between the} x2 axis and the horizontal direction according to the accelerations of the x2, y2 and z2 axes. The calculation formula is shown in formula 4:

Alternatively, the electronic device 100 may determine the angle between the subjects through the gyro sensor 180B. Exemplarily, the electronic device may include multiple gyroscope sensors, which are respectively disposed in each main body. The electronic device can detect the angular velocity of each axis (eg, x-axis, y-axis, and z-axis) of each main body (eg, main body 302, main body 303) through the gyro sensor provided in each main body (eg, main body 302, main body 303), according to the detected angular velocity on each axis The electronic device can determine the posture of each subject (e.g., the posture of the subject 302 and the posture of the subject 303), and then determine the angle between the subject according to the posture of any subject and the other subject (e.g., according to the posture of the subject 302 and the subject The posture of 303 determines the angle between the main body 302 and the main body 303).

Taking the double-folding mobile phone described in FIG. 3 as an example, the electronic device 100 may include a first gyroscope sensor and a second gyroscope sensor. Among them, the first gyroscope sensor is disposed on the main body 302; the second gyroscope sensor is disposed on the main body 303. The electronic device 100 can calculate the posture of the main body 302 by the angular velocity detected by the first gyro sensor, and calculate the posture of the main body 303 by the angular velocity detected by the second gyro sensor; then, according to the posture of the main body 302 and the posture of the main body 303, the electronic The device can determine the angle between the main body 302 and the main body 303.

It should be noted that the method of identifying the angle between the subjects in the embodiments of the present application includes but is not limited to the above examples. For example, the electronic device 100 may determine the angle between the subjects through the acceleration sensor 180E and the gyro sensor 180B. For another example, the electronic device 100 further includes a rotation sensor. The electronic device 100 can determine the angle between any body and the other body by detecting the rotation angle of the body through the rotation sensor.

It is understandable that when a plane forming the angle to be measured is parallel to a certain body, another plane forming the angle to be measured is parallel to the other body, and the angle between the angle to be measured and the two bodies is in the same direction , The angle of the angle to be measured is equal to the angle between the two main bodies. Exemplarily, as shown in FIG. 7, the angle to be measured is: the angle β between the plane 501 and the plane 502. The main body 302 of the electronic device is parallel to the plane 501 of the object 500 and the main body 303 of the electronic device is parallel to the plane 502 of the object, and the angle between the first plane 501 and the second plane 502 is the same as the angle between the main body 302 and the main body 303. , Then the angle β between the plane 501 and the plane 502 of the object is equal to the angle ɑ between the main body 302 and the main body 303. Therefore, in the embodiment of the present application, by identifying the angle ɑ between the main body 302 and the main body 303 when the main body 302 is parallel to the plane 501 and the main body 303 is parallel to the plane 502, the electronic device 100 can determine the clamp between the plane 501 and the plane 502. Angle β. In other words, when a plane constituting the angle to be measured is parallel to a certain main body, and another plane constituting the angle to be measured is parallel to another main body, the electronic device 100 can measure the angle to be measured by identifying the angle between the main bodies. Angle of angle. In the following embodiments, the structure of an electronic device related to angle measurement will be explained in more detail with reference to the accompanying drawings.

The electronic device 100 includes a parallel sensor 600. The parallel sensor 600 may be arranged on a certain main body of the electronic device 100 to detect the parallel relationship between a certain plane constituting the angle to be measured and the main body provided with the parallel sensor 600. For example, when the angle to be measured is the angle β between the plane 501 and the plane 502, the parallel sensor provided on the main body can be used to detect the parallel relationship between the plane 502 and the main body or the parallel relationship between the plane 501 and the main body. The working principle of the parallel sensor 600 will be described below in conjunction with FIG. 8.

According to the law of reflection, the angle of reflection is equal to the angle of incidence. As shown in Figure 8(a), when the main body (for example, main body 303) provided with the parallel sensor 600 is parallel to a certain plane (for example, plane 502), the transmitted wave is incident on the plane perpendicularly, and the reflected wave returns along the original path To the parallel sensor 600 (that is, the path of the reflected wave is the same as the path of the transmitted wave but opposite in direction), the reflected wave is received by the receiver. On the contrary, as shown in Figure 8(b) or Figure 8(c), when the body is not parallel to the plane, the transmitted wave is incident on the plane at a certain angle (for example, the incident angle is A), and the reflected wave is The path deviating from the original path returns (the angle between the path of the reflected wave and the path of the transmitted wave is twice the incident angle). At this time, the path of the reflected wave deviates from the parallel sensor 600, and the reflected wave received by the receiver is reduced, which is less than the reflected wave received by the receiver when it is parallel. It can be seen that, by detecting the reflected wave received by the receiver, the electronic device 100 can determine the parallel relationship between the main body (for example, the main body 303) provided with the parallel sensor 600 and a certain plane (for example, the plane 502). For example, when the receiver receives the most reflected waves, the electronic device 100 can determine that the body (for example, the body 303) provided with the parallel sensor 600 is parallel to the plane (for example, the plane 502) that reflects the transmitted waves.

It is understandable that, as shown in FIG. 7, when the plane to be measured (for example, plane 501) and the subject to be measured (for example, main body 302) are placed on the same plane (for example, the desktop), the plane to be measured is parallel to The subject to be tested. For another example, as shown in FIG. 8, when the plane to be measured is placed on a subject to be measured (for example, when the object 500 is placed on the main body 302 of the electronic device 100 with the plane 501 as the base), the plane to be measured is parallel On the subject to be tested.

That is to say, in the angle detection method in the embodiment of this application, the user can place a plane that forms the angle to be measured on a certain body of the electronic device, or place a plane that forms the angle to be measured on the body of the electronic device. On the same plane, so that a plane forming the angle to be measured is parallel to a main body. Then, the user can rotate the other main body of the electronic device so that the rotated other main body is parallel to the other plane constituting the angle to be measured. Thus, one plane constituting the angle to be measured is parallel to a main body of the electronic device, and another plane constituting the angle to be measured is parallel to the other main body. At this time, the angle between the two main bodies recognized by the electronic device is the angle to be measured.

Exemplarily, as shown in FIG. 8, an object 500 with a plane 501 as a base is placed on the main body 302 of the electronic device 100. At this time, the plane 501 is already parallel to the main body 302, and the electronic device 100 may not detect the parallel relationship between the plane 501 and the main body 302. It can be understood that when the main body 303 is parallel to the plane 502, the angle β between the plane 501 of the object and the plane 502 is equal to the angle ɑ between the main body 302 and the main body 303. The user can bend the display screen 194 inward or outward so that the main body 303 is parallel to the plane 502. Exemplarily, the user bends the display screen 194 inward from the first state where the angle ɑ between the main body 302 and the main body 303 of the electronic device is greater than the included angle β (as shown in FIG. 8(b)). The user bends the display 194 inward, the angle between the main body 302 and the main body 303 decreases accordingly, the main body 303 and the plane 502 tend to be parallel, and the reflected wave received by the receiver changes from less to more, until the main body 303 is parallel to the plane 502 (As shown in Figure 8(a)), the receiver receives the most reflected waves. Then, continue to bend the display screen 194 inward, and the angle between the main body 302 and the main body 303 continues to decrease, and the angle ɑ between the main body 302 and the main body 303 is smaller than the included angle β (as shown in FIG. 8(c)). As the user continues to bend the display screen 194 inward, the main body 303 and the plane 502 change from parallel to non-parallel, and the reflected waves received by the receiver change from more to less. It can be seen that when the main body 303 of the electronic device 100 is parallel to the plane 502 of the object, the receiver receives the most reflected waves. At this time, the angle between the main body 302 and the main body 303 is equal to the angle between the plane 501 and the plane 502. That is to say, when the receiver receives the most reflected waves, the electronic device can know the angle between the plane 501 and the plane 502 by identifying the angle between the main body 302 and the main body 303, thereby achieving a difference in the angle β. Angle measurement.

In the foregoing embodiment, FIG. 8 is taken as an example for description. It is understood that the embodiment of the present application includes but is not limited to the foregoing example. For example, as shown in FIG. 9(a), the user can bend the display screen 194 outward from the third state where the angle between the main body of the electronic device is smaller than the angle to be measured, so that the main body is parallel to the plane forming the angle to be measured. . As the user continues to bend the display screen 194 outward, the main body 303 and the plane 502 tend to be parallel, and the reflected wave received by the receiver changes from less to more. As shown in Figure 9(b), when the main body 303 and the plane 502 are parallel, the receiver receives the most reflected waves. By identifying the angle between the main body 302 and the main body 303, it is possible to know the clamping between the object plane 501 and the plane 502. Angle is the angle of the angle to be measured.

In the foregoing embodiment, FIG. 8 and FIG. 9 are taken as examples for description. It can be understood that the parallel sensor 600 may be a proximity optical sensor or an ultrasonic sensor. The parallel sensor 600 can be arranged on the same side as the display screen 194 or on the opposite side of the display screen 194. For example, as shown in FIG. 10(a), the parallel sensor 600 may be disposed on the side of the main body 302 opposite to the display screen. It is understandable that the electronic device 100 as shown in FIG. 10(a) can implement angle measurement according to the electronic device described in the above-mentioned embodiment, which will not be repeated here. The electronic device 100 may include one or more parallel sensors 600. For example, as shown in FIG. 10(b), the electronic device 100 includes two

parallel sensors

600a, 600b. They are respectively arranged on the main body 302 and the main body 303. It is understandable that the electronic device 100 as shown in FIG. 10(b) can bend the display screen 194 inward or outward so that the main body 302 is parallel to the plane 501 constituting the angle to be measured, and the main body 303 is parallel to the angle to be measured.的plane 502. When the main body 302 is parallel to the plane 501 forming the angle to be measured, the receiver of the parallel sensor 600a provided on the main body 302 receives the most reflected waves. When the main body 303 is parallel to the plane 502 constituting the angle to be measured, the receiver of the parallel sensor 600b provided on the main body 303 receives the most reflected waves. At this time, the electronic device 100 can know the angle of the angle to be measured by identifying the angle between the main body 302 and the main body 303. For the specific method of angle measurement, refer to the description in the above implementation, which will not be repeated here.

Optionally, the electronic device 100 may display angle information on the display screen 194 for the user to view. The angle information may include: the angle between the subjects recognized by the electronic device, and the result of the angle measurement of the electronic device.

For example, the electronic device 100 may recognize the angle between the main body 302 and the main body 303 and display the angle information on the display screen 194. For example, as shown in FIG. 11(a), when the angle between the main body 302 and the main body 303 recognized by the electronic device 100 is 60°, the electronic device may display "60°" on the display screen 194. When the user bends the display screen 194, the angle between the main body 302 and the main body 303 changes, and the angle information displayed on the display screen also changes accordingly.

For another example, the electronic device 100 can measure an angle, and display the result of the angle measurement on the display screen 194. For example, as shown in FIG. 11(b), when the electronic device determines that the angle to be measured is 52 degrees, the electronic device may display "52°" on the display screen 194.

Optionally, in order to facilitate the user to view or record the measurement result, the display of the measurement result may not disappear as the angle between the main body 302 and the main body 303 changes. For example, as shown in Figure 11(c), when the electronic device 100 displays the measurement result (52°), even if the angle between the main body 302 and the main body 303 changes (65°), the angle information displayed by the electronic device is still waiting Angle measurement result (52°). Optionally, the electronic device 100 may respond to the user's first operation to end the display of the measurement result. For example, as shown in FIG. 11(c), the first operation may be: double-click the display screen 194. As shown in FIG. 11(d), in response to the first operation, the electronic device 100 ends the display of the measurement result, and the electronic device 100 displays the angle between the main body 302 and the main body 303 currently recognized by the electronic device.

It is understandable that the electronic device can display one or more angle information. For example, the electronic device may display the results of multiple angle measurements, or the electronic device may simultaneously display the measurement results and the angles between the subjects.

Optionally, the electronic device 100 may determine the display position of the display information, so that the displayed angle information is convenient for the user to view. Exemplarily, the electronic device may determine the display position of the display information according to the motion state of each subject. As shown in Figure 10(a), when the electronic device is placed on the desktop with the main body 303 as the bottom, the position of the main body 303 is fixed, and the user bends the main body 302 inward or outward to make the main body 303 parallel to the second plane 502. If the main body 302 is in a motion state, the electronic device can preferentially display information on the part of the display screen 194 corresponding to the main body 302, so that the user can view the displayed angle information.

In the above embodiment, a double-folding mobile phone is taken as an example for description. It can be understood that the electronic device can be connected to more main bodies through more connection units. For example, the electronic device may be a three-folding mobile phone. FIG. 12 is a schematic structural diagram of yet another electronic device 100 provided by an embodiment of the application. As shown in FIG. 12, the electronic device 100 includes: a connection unit 401, a connection unit 402, a main body 403, a main body 404, and a main body 405. The connecting unit 401 is used for connecting the main body 403 and the main body 404, and the connecting unit 402 is used for connecting the main body 404 and the main body 405. The display screen 194 covers the connection unit 401, the connection unit 402, the main body 403, the main body 404, and the main body 405. The main body 403 and the main body 404 and the main body 405 may have the same size and thickness. The display screen 194 can be bent inward or outward through the connecting unit 401 to change the angle between the main body 403 and the main body 404, and the connecting unit 402 can be bent inward or outward to change the angle between the main body 404 and the main body 405.

In the foregoing embodiment, the electronic device 100 including main bodies of the same size is taken as an example for description. It is understandable that the sizes of the main bodies may be different. For example, as shown in FIG. 13(a), the main body 302 may be larger than the main body 303. The size of the main body 403, the main body 404 and the main body 405 may also be different. For example, as shown in FIG. 13(b), the sum of the width of the main body 403 and the main body 405 is equal to the width of the main body 404.

It can be understood that, similarly, the electronic device 100 can recognize the angles between the main bodies, such as the angle between the main body 403 and the main body 404, the angle between the main body 404 and the main body 405, and the angle between the main body 403 and the main body 405. . The method of identifying the angle between the main body 403 and the main body 404, the method of identifying the angle between the main body 404 and the main body 405, or the method of identifying the angle between the main body 403 and the main body 405, refer to the description in FIG. Repeat.

It is understandable that, similarly, as shown in FIG. 15, the electronic device 100 can bend the display screen 194 so that any two main bodies of the electronic device are respectively parallel to the two planes forming the angle to be measured, and then identify the arbitrary The angle between the two main bodies can be used to measure the angle to be measured, which will not be repeated here.

It should be noted that when the electronic device includes N main bodies, the electronic device 100 can perform angle measurement on N-1 angles to be measured at the same time. Exemplarily, as shown in FIG. 15, when the electronic device includes three main bodies, the electronic device can simultaneously measure two angles to be measured. As shown in Figure 15(a), the electronic device detects whether the first body (eg, body 403) is parallel to the first plane (eg, plane 501); the electronic device detects whether the third body (eg, body 405) is parallel to the third plane (E.g., the plane 503) is parallel; the electronic device recognizes the angle between the first body and the second body; the electronic device recognizes the first body and the second body (e.g., the main body 404) The angle between. When the first body is parallel to the first plane, the angle between the second body and the third body recognized by the electronic device is equal to the angle β _{1 of the} first angle to be measured; when the third plane is parallel to the third body, the electronic device recognizes The angle between the second body and the third body is equal to the angle β _{2 of the} second angle to be measured. Or, as shown in FIG. 15(b), the electronic device detects whether the second body (eg, body 404) is parallel to the second plane (eg, plane 502); the electronic device detects whether the third body (eg, body 405) is parallel to the first Whether the three planes (eg, plane 503) are parallel; the electronic device recognizes the angle between the first body and the second body; the electronic device recognizes the first body (eg, the main body 403) and the second body The angle between the subjects. When the second body is parallel to the second plane, the angle between the first body and the second body recognized by the electronic device is equal to the angle β _{1 of the} first angle to be measured; the third plane is parallel to the third body and the second plane is parallel to the first When the two bodies are parallel, the angle between the second body and the third body recognized by the electronic device is equal to the angle β _{2 of the} second angle to be measured.

The method provided by the embodiment shown in FIG. 16 below is applied to the electronic equipment provided by the foregoing embodiments.

As shown in FIG. 16, an angle measurement method provided by an embodiment of the present application includes:

Step 1601: The electronic device detects whether at least one main body of the electronic device is parallel to at least one plane of the angle to be measured.

It is assumed that the angle to be measured is the angle between the first plane (eg, plane 501) and the second plane (eg, plane 502). The electronic device includes at least a first body (eg, body 302) and a second body (body 303).

The electronic device detects whether the first body (eg, body 302) of the electronic device is parallel to the first plane (eg, plane 501), and the second body (eg, body 303) of the electronic device is parallel to the second plane (plane 501). 502) Is it parallel? Or, when the first body and the first plane are already parallel, the electronic device may only detect whether the second body and the second body are parallel. When the second body and the second plane are already parallel, the electronic device can only detect whether the first body and the first body are parallel.

Specifically, the electronic device detects whether the main body is parallel to the plane through a parallel sensor.

Exemplarily, if the reflected wave received by the parallel sensor is greater than a predetermined threshold, the electronic device determines that the main body is parallel to the plane. Conversely, if the reflected wave received by the parallel sensor is less than a predetermined threshold, the electronic device determines that the main body is not parallel to the plane.

Alternatively, the user bends the display screen 194 inward or outward to rotate the main body so that the main body is parallel to the plane constituting the angle to be measured. As the user turns the main body by bending the display screen 194 inward or outward, the value of the reflected wave received by the parallel sensor provided on the main body changes from a small value to a peak value (ie, a maximum value), and then from a large value. Become smaller. If the reflected wave received by the parallel sensor is a peak, the electronic device determines that the main body is parallel to the plane. Conversely, if the reflected wave received by the parallel sensor is less than the peak value, the electronic device determines that the main body is not parallel to the plane.

Step 1602, the electronic device recognizes the angle between the subjects.

Specifically, the electronic device recognizes the angle between the first body and the second body. For the method of identifying the angle between the subjects, refer to the description in the foregoing embodiment, and will not be repeated here.

Step 1603: The electronic device outputs the angle between the main body recognized by the electronic device when the main body is parallel to the plane.

Specifically, when the angle to be measured is the angle between the first plane and the second plane, the angle of the angle to be measured is that the first body is parallel to the first plane and the second body is parallel to the first plane. When the two planes are parallel, the angle between the first body and the second body recognized by the electronic device.

Exemplarily, the electronic device may display the angle of the angle to be measured on the display screen 194. It should be noted that the embodiment of the present application does not limit the manner of outputting the angle of the angle to be measured. For example, the electronic device can output by voice.

It should be noted that the embodiment of the present application does not limit the sequence of step 1601 and step 1602. Step 1601 may be performed first, or step 1602 may be performed first, or step 1601 and step 1602 may be performed simultaneously. In other words, the electronic device can recognize and record the angle between the first body and the second body in real time. After the electronic device detects that the body is parallel to the plane forming the angle to be measured, it outputs the corresponding first body and second body It is also possible to first detect whether the main body is parallel to the plane constituting the angle to be measured, and then identify the angle between the first main body and the second main body after detecting that the main body is parallel to the plane constituting the angle to be measured.

Exemplarily, as shown in FIG. 10(a), the electronic device includes a first body (eg, body 302), a second body (eg, body 303), and a device for connecting the first body and the second body The first connection unit (for example, the connection unit 301) and the first parallel sensor 600 provided on the first body. The user places the object 500 to be measured on the second main body (eg, main body 303) of the electronic device 100 with the second plane (eg, plane 501) constituting the angle to be measured as the bottom. At this time, the second plane is parallel to the second body. The electronic device may not detect the parallel relationship between the second plane and the second body. The electronic device detects whether the first body (for example, the body 302) is parallel to the first plane (for example, the plane 502) constituting the angle to be measured. If the reflected wave received by the first parallel sensor 600 is less than the predetermined threshold, the electronic device determines that the first body is not parallel to the first plane, and the electronic device outputs a first prompt, prompting that the first body is not parallel to the first plane, and prompting the user to rotate The first subject. The user rotates the first body, and if the reflected wave received by the first parallel sensor 600 is still less than the predetermined threshold, the first prompt will continue to be output until the reflected wave received by the first parallel sensor 600 is greater than the predetermined threshold, and the electronic device determines the first The main body is parallel to the first plane. The electronic device recognizes the angle between the first body and the second body. The electronic device outputs the angle between the first body and the second body when the first body is parallel to the first plane.

Exemplarily, as shown in FIG. 10(b), the electronic device includes a first body (eg, body 302), a second body (eg, body 303), and is used to connect the first body and the second body A first connection unit (eg, connection unit 301), a first parallel sensor (eg, parallel sensor 600a) disposed on the first body, and a second parallel sensor (eg, parallel sensor 600b) disposed on the second body. The electronic device detects whether the first body 302 is parallel to the first plane 501 and whether the second body 503 is parallel to the second plane 502.

When the first body is not parallel to the first plane, the electronic device outputs a first prompt, prompting the user that the first body is not parallel to the first plane, and prompting the user to rotate the first body. When the second body is not parallel to the second plane, the electronic device outputs a second prompt, prompting the user that the second body is not parallel to the second plane, and prompting the user to rotate the second body. First, the user can bend the display screen 194 inward or outward to rotate the first body so that the first body is parallel to the first plane. If the reflected wave received by the first parallel sensor is less than the predetermined threshold, the electronic device determines that the first body is not parallel to the first plane, and the electronic device continues to output the first prompt until the reflected wave received by the first parallel sensor is greater than the predetermined threshold, The electronic device determines that the first body is parallel to the first plane, and the electronic device outputs a third prompt to prompt the user that the first body is parallel to the first plane. Then, keeping the first body unchanged, the user bends the display screen 194 inward or outward to rotate the second body so that the second body is parallel to the second plane. If the reflected wave received by the second parallel sensor is less than the predetermined threshold, the electronic device determines that the second body is not parallel to the second plane, and the electronic device continues to output a second prompt until the reflected wave received by the second parallel sensor is greater than the predetermined threshold, The electronic device determines that the second body is parallel to the second plane, and the electronic device outputs a fourth prompt to prompt the user that the second body is parallel to the second plane. Then, the electronic device recognizes the angle between the first body and the second body, and outputs the angle between the first body and the second body, that is, the angle to be measured.

Optionally, when the first body is not parallel to the first plane, the electronic device outputs a first prompt, prompting the user that the first body is not parallel to the first plane, and prompting the user to rotate the first body. When the second body is not parallel to the second plane, the electronic device outputs a second prompt, prompting the user that the second body is not parallel to the second plane, and prompting the user to rotate the second body. The user rotates the first body so that the first body is parallel to the first plane. The reflected wave received by the first parallel sensor is greater than a predetermined threshold, the electronic device determines that the first body is parallel to the first plane, and the electronic device outputs a third prompt to prompt the user that the first body is parallel to the first plane. The electronic device starts to recognize and record the angle between the first body and the second body. Then, the user bends the display screen 194 inward or outward to rotate the second body so that the second body is parallel to the second plane. When the second body is parallel to the second plane, the recorded angle between the first body and the second body is the angle to be measured. Compared with the foregoing embodiment, there is no need for the user to keep the second plane parallel to the second body at this time. It should be noted that in the above embodiment, the first body is first rotated, and the second body is rotated after the first body is parallel to the first plane. It is understood that the second body can also be rotated first. If you turn the first body again, you can also rotate the first body and the second body together.

To sum up, bending the display 194 changes the angle between the main bodies so that the main body is parallel to the plane constituting the angle to be measured, and then by identifying the angle between the main bodies, the measurement of the angle to be measured can be realized, which is convenient for users. The angle is measured by a deformable electronic device.
