Detailed ways

In order to enable those in the technical field to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

With the development of display technology in electronic devices, more and more electronic devices use scroll-type screens. Scroll-type electronic devices can not only provide users with a larger display area during use, but also can provide users with a larger display area without the need for a large display screen. The screen is closed when the area is selected, making it easier for users to carry it.

However, the size of the screen of a roll-type electronic device is relatively large when the screen is fully unfolded. If the electronic device falls, the screen will most likely be impacted and damaged. In addition, the screen cost of scroll-type electronic equipment is high, and maintenance will consume a lot of manpower and material resources.

In response to the above problems, the inventor proposes a screen protection method, device, electronic device and storage medium provided by embodiments of the present application, which can accurately detect that the electronic device is in a falling state and control the screen of the electronic device to close, thereby reducing the risk of the electronic device falling. Damage to the screen caused by impact, achieving screen protection for scroll-type electronic devices. The specific screen protection method will be described in detail in subsequent embodiments.

The scenarios involved in the embodiments of this application are first introduced below.

As shown in Figure 1, Figure 1 shows a scroll type electronic device 100. The electronic device 100 includes a screen 130. The screen 130 includes a first display area 131 and a second display area 132. The second display area 132 is selectively closed or expanded relative to the first display area 131, so that the first display area 131 and the second display area 132 can be displayed simultaneously or non-simultaneously. As shown in Figure 1, when the screen 130 is expanded, the second display area 132 is expanded relative to the first display area 131. At this time, the first display area 131 and the second display area 132 are displayed at the same time; as shown in Figure 2 , when the screen 130 is closed, the second display area 132 is hidden relative to the first display area 131. At this time, the first display area 131 and the second display area 132 are not displayed simultaneously. The screen 130 may be a flexible display screen.

The screen protection method provided by the embodiment of the present application will be introduced in detail below with reference to the accompanying drawings.

Please refer to Figure 3. Figure 3 shows a schematic flowchart of a screen protection method provided by an embodiment of the present application. In a specific embodiment, the screen protection method is applied to the above-mentioned electronic device. The screen of the electronic device includes a first display area and a second display area. The second display area is selectively opposite to the first display area. The display area collapses or expands. The process shown in Figure 3 will be described in detail below. The screen protection method may specifically include the following steps:

Step S110: When it is detected that the electronic device is in a weightless state, determine that the electronic device is in a falling state based on the current motion data of the electronic device.

Among them, the weightless state refers to the state when the electronic device is only affected by gravity, that is, the state of free fall. It should be noted that in actual scenarios, when an electronic device is in a free fall state, it is also affected by air resistance, but usually the air resistance is very small and can be ignored. At this time, the terminal can be considered to be in a weightless state. In this embodiment of the present application, the electronic device can detect the state of the electronic device through an internal sensor, thereby detecting whether the electronic device is in a weightless state.

In some embodiments, an acceleration sensor is provided in the electronic device to obtain the acceleration of the electronic device in real time, and determine whether the electronic device is in a weightless state based on the obtained acceleration. Among them, the acceleration in three mutually perpendicular axes can be obtained through the acceleration sensor, and then it can be determined whether the acceleration in the three axes is less than the preset acceleration. If the acceleration in the three axes is less than the preset acceleration, then it can be Make sure the electronic device is in a weightless state.

For example, the above three axes can be the x-axis, y-axis, and z-axis. The plane formed by the x-axis and the y-axis is the plane where the screen is located, and the x-axis and the y-axis are perpendicular to each other, and the z-axis is perpendicular to the x-axis and the y-axis. The formed plane is vertical, and the z-axis can take vertical downward as the positive direction. When the electronic device is in a stationary state, the force arm in the acceleration sensor deforms due to gravity, thereby sensing the gravity acceleration g in the z-axis direction. Under normal circumstances, it can be considered that g=9.8m/s ² ; when the electronic device is in In the free fall state, the acceleration sensor in the electronic device is also in the free fall state. At this time, the deformation of the force arm in the acceleration sensor due to gravity disappears. At this time, the acceleration sensor senses that the acceleration of the z-axis is 0 and the x-axis Since the y-axis direction is not affected by other external forces, the acceleration sensed in the x-axis and y-axis directions is also 0.

In this implementation, the above preset acceleration is an acceleration value pre-stored in the electronic device. For example, the default acceleration is 9.8m/s ² . After the electronic device obtains the acceleration in three axial directions through the acceleration sensor, it retrieves the preset acceleration in the memory of the electronic device. Compare the acceleration in the three axial directions with the preset acceleration respectively to determine whether the acceleration in the three axial directions is less than the preset acceleration. When making comparisons, the acceleration magnitudes in the three axes are all taken as absolute values. In practical applications, when an electronic device is in a free fall state, the electronic device will also be subject to air resistance, and the air resistance will affect the acceleration detected in the movement direction of the electronic device (ie, the z-axis direction). At the same time, since there will be a certain error in the detection of the sensor, the acceleration detected during free fall is not necessarily 0. For example, if the obtained x-axis acceleration is 0.01m/s ² , the y-axis acceleration is 0.02m/s ² , and the z-axis acceleration is 0.05m/s ² , then the accelerations in the three axes are all smaller than the preset values. With an acceleration of 0.5m/s ² , it can be determined that the electronic device enters a weightless state.

In the embodiment of the present application, when the electronic device detects that it is in a weightless state, the electronic device may be in a falling state at this time, or the electronic device may be in a weightless state when the user normally uses the electronic device. For example, the user carries The electronic device quickly sits down, or the user places the electronic device, etc., so the electronic device can further determine whether it is in a dropped state. Among them, the current motion data of the electronic device can be obtained, and whether it is in a falling state is determined based on the current motion data.

In some implementations, current motion data may include angular acceleration, linear acceleration, and altitude data. Among them, angular acceleration can be detected by a gyroscope. A gyroscope is also called an angular velocity sensor. Electronic equipment is usually equipped with a three-axis gyroscope, which can track displacement changes in six directions and obtain the three-axis position of the electronic equipment in x, y, and z. The angular acceleration in the direction can be used to measure the rotation and deflection of mobile phones, so as to perform corresponding operations on electronic devices. In electronic devices, gyroscopes are usually used in games, camera anti-shake, navigation, etc.; Linear acceleration can be detected by an acceleration sensor, and altitude can be detected by a barometer. Of course, the specific method of detecting the above motion data does not need to be limited. Since the above current motion data includes motion data in multiple dimensions, whether the electronic device is in a falling state can be accurately determined based on the current motion data. It can be understood that since the above current motion data includes a lot of data, determining whether the electronic device is in a dropped state based on the current motion data requires more processing resources and generates more power consumption than detecting whether the electronic device is in a weightless state. It is also larger. Therefore, when the electronic device detects that it is in a falling state, it can then determine whether it is in a falling state based on the current motion data, which can avoid unnecessary calculations and thus save the power consumption of the electronic device.

In some embodiments, the electronic device can match the current motion data with the motion data obtained during a fall from a preset test in the electronic device. If the current motion data matches the preset motion data, it can be determined that the electronic device is in a fall. status; if the current motion data does not match the preset motion data, it can be determined that the electronic device is not in a falling state.

In other embodiments, the electronic device may also be pre-set with a detection model for detecting a drop state, and the detection model may be trained based on the motion data obtained during the fall during the test. When the electronic device determines whether it is in a falling state based on the current motion data, it can input the current motion data into the detection model, and determine whether it is in a falling state based on the results output by the detection model.

In some embodiments, when the electronic device is in use, continuously detecting whether it is in a weightless state will also result in greater power consumption. Therefore, the electronic device can detect whether it is in a weightless state when the corresponding screen protection conditions are met, thereby eliminating the need to constantly detect whether it is in a weightless state, thereby saving power consumption of the electronic device.

In a possible implementation, since scroll-type electronic devices are prone to damage to the screen when the screen is in an unfolded state, the unfolded state of the screen can be detected, that is, whether the second display area is unfolded relative to the first display area, The detection of whether the second display area is in a weightless state is only performed when the second display area is expanded relative to the first display area.

Optionally, the electronic device can detect the angle between the first display area and the second display area to determine whether the second display area is in a state of being expanded relative to the first display area; after detecting the angle between the first display area and the second display area, After determining the angle between the second display areas, it can be determined based on the above detected angle whether the second display area is in a state of being expanded relative to the first display area. Wherein, when the angle between the first display area and the second display area is less than the set value, it can be determined that the second display area is closed relative to the first display area; it can be between the first display area and the second display area. When the angle is greater than or equal to the set value, it is determined that the second display area is expanded relative to the first display area. The above setting value may be an angle value when the first display area and the second display area are nearly parallel. For example, the setting value may be 0, 3, 5, etc.

In this method, the electronic device can use the above-mentioned angle detection module to detect the angle between the first display area and the second display area. The electronic device may also detect the repulsive force between the magnet provided in the first display area and the magnet provided in the second display area, thereby determining the first display area based on the repulsive force between the magnets between the first display area and the second display area. The angle between the display area and the second display area. It can be understood that when the magnets arranged in the first display area and the magnets arranged in the second display area are closer, the repulsive force between the magnets detected by the electronic device will be The larger the angle is, the closer the magnets are to each other, which means the smaller the angle between the first display area and the second display area. When the first display area and the second display area are relatively unfolded, the magnets are the farthest apart. Therefore, the angle formed between the first display area and the second display area can be determined based on the above-mentioned detected repulsive force, and whether the second display area is in a state of expansion relative to the first display area can be determined. Of course, the specific method of detecting the angle between the first display area and the second display area may not be limited in the embodiments of the present application.

In another possible implementation, a screen saver mode can be set in the electronic device. If the screen saver mode is turned on, the electronic device can detect whether it is in a weightless state; if the screen saver mode is not turned on, the electronic device The device does not perform detection of weightlessness. In this embodiment, a switch corresponding to the screen saver mode can be set, and the electronic device can respond to the operation of the switch and control the screen saver mode to be on or off, thereby determining whether to execute the screen saver mode according to the user's needs. Detecting whether it is in a weightless state and subsequent steps, that is, protecting the screen according to the user's needs.

Step S120: In response to the electronic device being in a falling state, control the second display area to close relative to the first display area.

In the embodiment of the present application, when the electronic device determines that the electronic device is in a falling state based on the current motion data, the second display area can be controlled to close relative to the first display area in response to the electronic device being in a falling state, thereby causing The second display area is hidden in the casing, effectively protecting the second display area, and the screen size is reduced, which can reduce damage to the screen when the electronic device hits it, thereby achieving effective protection for scroll-type screens.

In some embodiments, the electronic device may be provided with a motor that controls the closing and unfolding of the screen. When the electronic device determines that it is in a falling state, it can drive the motor to operate to control the second display area to close relative to the first display area.

In some embodiments, when the electronic device determines that the electronic device is in a fallen state based on the current motion data, the electronic device can also determine the height at which it is located, and compare the determined height with the preset height; if the electronic device is If the height of the electronic device is greater than or equal to the preset height, the second display area can be controlled to close relative to the first display area; if the height of the electronic device is less than the preset height, the second display area does not need to be controlled to close relative to the first display area. . Among them, the height of the electronic device can be detected by a barometer built into the electronic device.

In this implementation, the purpose of obtaining the height of the electronic device is to determine whether the electronic device fell from a lower height. If the height of the electronic device is less than the preset height, it means that the electronic device fell from a lower height. In this case, the screen is not controlled to close. This is because the electronic device will collide with the ground or object in a short period of time. The screen cannot be fully closed during the impact. If it is closed temporarily, it is easy to cause secondary damage to the screen; on the other hand, falling from a lower height may not cause damage to the screen of the electronic device, so there is no need to control the screen to close, thereby reducing unnecessary power consumption. .

In some embodiments, a protective device, such as a protective case, is provided around the housing of the electronic device. The protective device can be selectively hidden in the housing or protruded from the housing. When the electronic device controls the second display area to close relative to the first display area in response to the fact that the electronic device is in a falling state, the electronic device can synchronously control the protection device to extend from the housing to protect the screen of the electronic device.

In some embodiments, when the electronic device determines that the electronic device is in a falling state based on the current motion data, it can also control the operation of its internal motor to cause the electronic device to rotate in the air, thereby releasing gravitational potential energy and reducing the risk of falling. Damage to the screen during collision.

The screen protection method provided by the embodiment of the present application, by detecting that the electronic device is in a weightless state, and then determining whether the electronic device is in a falling state based on the current motion data, not only accurately detects that the electronic device is in a falling state, but also can save electronics. The power consumption of the device is determined, and when it is determined that the electronic device is in a dropped state, the second display area is controlled to be closed relative to the first display area, thereby reducing the damage to the screen caused by impact when the electronic device is dropped, and realizing the protection of scroll-type electronic devices. screen saver.

Please refer to FIG. 4 , which shows a schematic flowchart of a screen protection method provided by another embodiment of the present application. This screen protection method is applied to the above-mentioned electronic device. The screen of the electronic device includes a first display area and a second display area. The second display area is selectively closed or expanded relative to the first display area. The process shown in Figure 4 will be described in detail below. The screen protection method may specifically include the following steps:

Step S210: When it is detected that the electronic device is in a weightless state, determine that the electronic device is in a falling state based on the current motion data of the electronic device.

Step S220: In response to the electronic device being in a falling state, control the second display area to close relative to the first display area.

In the embodiment of the present application, the content of steps S210 and S220 can be referred to other embodiments, and will not be described again here.

Step S230: In response to detecting that the electronic device is in a collision state, suspend the control of the second display area to close relative to the first display area.

In the embodiment of the present application, when the electronic device falls, in addition to controlling the second display area to close relative to the first display area when the electronic device falls, the screen can also be protected at other stages during the fall of the electronic device. Understandably, the falling process of electronic equipment is mainly divided into the following order: the initial stage (the normal holding or placing state when the user uses the electronic equipment), the stage in the falling state, the collision stage with the ground or objects, and the post-collision stage. Buffering phase and resting state. When the electronic device detects that it is in a falling state, and the electronic device is still in the falling state, the screen is controlled to close, and then after the electronic device drops to a certain height, it is in the collision stage of colliding with the ground or object. If it collides with the ground or object, When an object collides, continuing to control the screen to close it will cause friction between the screen and the ground or objects, resulting in secondary scratches or dust on the screen. Therefore, when it is detected that the electronic device is in a collision state, the control can be suspended. The second display area is collapsed relative to the first display area.

In some implementations, the electronic device can determine the stage the electronic device is in when it falls through its current motion data. It is understandable that the angular acceleration, linear acceleration, and height of the electronic device will be different during the falling phase, the collision phase with the ground or an object, the buffer phase after the collision, and the stationary state. Therefore, based on the current situation of the electronic device, Motion data can determine the stage an electronic device was in when it was dropped.

Step S240: In response to detecting that the electronic device is in a stationary state, obtain the orientation of the screen.

In the embodiment of the present application, after the electronic device collides with the ground or an object, it will enter a static state after the buffering stage after the collision. When detecting that the electronic device is in a static state, it can respond to detecting that the electronic device is in a static state. In the static state, continue to control the screen to close to protect the screen. Before continuing to control the second display area to close relative to the first display area, the orientation of the screen may be obtained to determine whether to continue to control the second display area to close relative to the first display area according to the orientation of the screen. Optionally, the electronic device can detect its posture through a gyroscope or the like to determine the orientation of the screen.

Step S250: If the orientation of the screen is a target direction, continue to control the second display area to close relative to the first display area, wherein the target direction is opposite to the direction of gravity.

In the embodiment of the present application, after obtaining the orientation of the screen, it can be determined whether the orientation of the screen is the target direction. The target direction is opposite to the direction of gravity. If the orientation of the screen is the target direction, it means that the screen is facing upward. At this time Then you can continue to control the second display area to close relative to the first display area; conversely, if the orientation of the screen is not the target direction, if you continue to control the second display area to close relative to the first display area, it may cause the screen to be in contact with the ground or object. If friction occurs, you can continue to close the screen without controlling it.

In some embodiments, after detecting that the electronic device is in a stationary state, the electronic device can also detect the working status of the target hardware module of the electronic device; and generate a drop detection report of the electronic device based on the detected status of the target hardware module of the electronic device. . Among them, the target hardware module can include Bluetooth, WiFi module, camera module, SIM card slot, etc., and the specific hardware module is not limited; the working status of the target hardware module is used to indicate whether the target hardware module is working normally. Optionally, Determine the working status of the target hardware module by detecting the power-on connectivity status of the target hardware module. After the electronic device detects the working status of the target hardware module, it can generate a drop detection report including the working status of the target hardware module for this drop, so as to provide reference for maintenance personnel and for manufacturers to maintain electronic equipment. Provide basis for improvement.

In a possible implementation, after the electronic device generates the above drop detection report, it can upload the drop detection report, the time, location and motion data of the fall and other information to the manufacturer's server, so as to provide maintenance services for the electronic device for the manufacturer. It can also provide a basis for improvement and avoid being unable to determine whether the failure of the hardware module was caused by a drop during maintenance.

Optionally, when it is detected that the electronic device is in a weightless state, and if it is determined that the electronic device is in a falling state based on the current motion data of the electronic device, the camera can also be controlled to shoot and the captured video can be saved. When sending the above drop detection report to the manufacturer's server, the captured video can also be sent to the manufacturer's server to provide evidence for the drop detection report to prove the hardware module during maintenance when the hardware module fails. of failures caused by falls, thus avoiding unnecessary disputes.

The screen protection method provided by the embodiment of the present application, by detecting that the electronic device is in a weightless state, and then determining whether the electronic device is in a falling state based on the current motion data, not only accurately detects that the electronic device is in a falling state, but also can save electronics. The power consumption of the device is determined, and when it is determined that the electronic device is in a dropped state, the second display area is controlled to be closed relative to the first display area, thereby reducing the damage to the screen caused by impact when the electronic device is dropped, and realizing the protection of scroll-type electronic devices. screen saver. In addition, it also provides screen protection measures for other stages after the electronic device is dropped, protecting the screen more effectively.

Please refer to FIG. 5 , which shows a schematic flowchart of a screen protection method provided by yet another embodiment of the present application. This screen protection method is applied to the above-mentioned electronic device. The screen of the electronic device includes a first display area and a second display area. The second display area is selectively closed or expanded relative to the first display area. The process shown in Figure 5 will be described in detail below. The screen protection method may specifically include the following steps:

Step S310: When it is detected that the electronic device is in a weightless state, match the current motion data of the electronic device with preset motion data. The preset motion data includes the test device corresponding to the electronic device. The first motion data in a real fall state and the second motion data in a weightless state when the test device is in use.

The electronic device may pre-store the first motion data when the corresponding test device is in a real fall state, and the second motion data when the test device is in a weightless state during use. Among them, the first movement data and the second movement data include angular acceleration, linear acceleration, height data, etc.; the first movement data when the test equipment is in a real falling state refers to the movement data measured when the test equipment is dropped in advance. ; The second movement data when the test equipment is in a weightless state during use refers to the movement data measured when the test equipment is used in advance and placed in a weightless state. For example, you can sit down quickly while carrying electronic equipment, place electronic equipment Motion data is measured under conditions such as equipment. The above first motion data and second motion data may be stored in the electronic device before the electronic device leaves the factory, or may be sent to the electronic device for storage by the manufacturer's server after the electronic device is used, which is not limited here.

In the embodiment of the present application, when the electronic device detects that it is in a weightless state and determines whether it is in a falling state based on its current motion data, the current motion data can be compared with the above first motion data and the second motion data. Match to determine whether the electronic device is in a dropped state based on the matching results.

Step S320: If the current motion data matches the first motion data, and the current motion data does not match the second motion data, determine that the electronic device is in a falling state.

In the embodiment of the present application, after the electronic device obtains the matching result between the current motion data and the above first motion data and the second motion data, if the current motion data matches the first motion data, and the current motion data matches the second motion data, If the motion data does not match, it means that the electronic device is in a weightless state under a real fall state, rather than a weightless state during normal use. Therefore, it can be determined that it is in a dropped state. Since the current motion data is compared with the first motion data and the second motion data respectively, The data is matched, and whether the electronic device is in a dropped state is determined based on the matching results. Therefore, dual detection of whether the electronic device is in a dropped state can be achieved and the accuracy of detecting the dropped state can be improved.

In some embodiments, after the electronic device obtains the matching result between the current motion data and the above first motion data and the second motion data, if the current motion data matches the first motion data, and the current motion data matches the first motion data, The two motion data are matched. At this time, it is impossible to determine whether the electronic device is in a falling state directly based on the matching results. In this case, the touch state of the electronic device can be determined. If the electronic device is not touched, it can be determined that the electronic device is in a fallen state; if the electronic device is in a touched state, it can be determined that the electronic device is not in a fallen state. . Among them, the electronic device can determine whether the electronic device is in a touched state based on whether the screen is touched and the touch sensor, pressure sensor, etc. provided on the housing.

Step S330: In response to the electronic device being in a falling state, control the second display area to close relative to the first display area.

In the embodiment of this application, the content of step S330 can be referred to other embodiments, and will not be described again here.

The screen protection method provided by the embodiment of the present application, when it is detected that the electronic device is in a weightless state, then combines the current motion data with the first motion data when the test device is in a real fall state and the weightless state when the test device is in use. The second motion data is matched, and whether the electronic device is in a falling state is determined based on the matching result. Thus, dual detection of whether the electronic device is in a falling state can be achieved, and the accuracy of detecting the falling state can be improved. And when it is determined that the electronic device is in a fallen state, the second display area is controlled to be closed relative to the first display area, thereby reducing damage to the screen caused by impact when the electronic device falls, and achieving screen protection for scroll-type electronic devices.

Please refer to FIG. 6 , which shows a schematic flowchart of a screen protection method provided by yet another embodiment of the present application. This screen protection method is applied to the above-mentioned electronic device. The screen of the electronic device includes a first display area and a second display area. The second display area is selectively closed or expanded relative to the first display area. The process shown in Figure 6 will be described in detail below. The screen protection method may specifically include the following steps:

Step S410: When it is detected that the electronic device is in a weightless state, input the current motion data of the electronic device into a drop detection model. The drop detection model is based on the fact that the test equipment corresponding to the electronic device is in a real drop state. The third motion data is obtained by training with the test device and the fourth motion data is not in the falling state. The fourth motion data at least includes the motion data in the weightless state when the test device is in use.

In this embodiment of the present application, the electronic device stores a drop detection model trained based on the third motion data of the test device corresponding to the electronic device in a real fall state and the fourth motion data not in a fall state, and The fourth motion data at least includes motion data when the test device is in a weightless state when in use. When the electronic device detects that it is in a state of weightlessness and determines whether it is in a fall state based on its current motion data, the current motion data can be input to the fall detection model, so that based on the results output by the fall detection model, it can be determined whether the electronic device is in a state of weightlessness. In a dropped state.

In some implementations, the fall detection model can be trained in the following manner:

Obtain the third motion data of the test device corresponding to the electronic device when it is in a real fall state and the fourth motion data when it is not in the fall state. The fourth motion data at least includes the weightless state of the test device when in use. motion data; based on the third motion data and the fourth motion data, train the initial detection model to obtain the fall detection model.

Among them, the initial detection model can be a neural network, etc. By labeling the third motion data as a falling state, labeling the fourth motion data as a non-falling state, and then using the labeled third motion data and fourth motion data to train the initial detection model, a fall detection model can be obtained .

In some implementations, the above drop detection model may be obtained by the server pre-training the initial detection model based on the above third motion data and the above fourth motion data. After the server obtains the above drop detection model through training, it sends the drop detection model to the electronic device, and the electronic device saves the received drop detection model. In addition, the server can also collect the movement data of the user's electronic equipment when it is actually dropped during use, as well as the movement data of the weightless state during use, and continuously update and train the drop detection model based on the collected movement data, and The updated and trained drop detection model is delivered to the electronic device to ensure the accuracy of the drop detection model. Of course, the above drop detection model can also be pre-trained by the manufacturer and stored in the electronic device before it leaves the factory.

Step S420: Based on the result output by the drop detection model, determine that the electronic device is in a dropped state.

In the embodiment of the present application, after obtaining the output result of the drop detection model, it can be determined whether the electronic device is in a dropped state based on the output result. Optionally, if the output result is a first result, such as output 0, it can be determined that the electronic device is in a dropped state; if the output result is a second result, such as output 1, it can be determined that the electronic device is not in a dropped state. Understandably, since the sample data used in training the above drop detection model not only includes motion data in a real fall state, but also motion data in a weightless state during use, the trained fall detection model can accurately distinguish real falls. state and a suspected dropped state (that is, a state of weightlessness during use), so it can accurately detect whether the electronic device is in a dropped state.

Step S430: In response to the electronic device being in a falling state, control the second display area to close relative to the first display area.
