It should be understood that, in the conventional technology, the electronic device 1000 usually directly determines whether the electronic device 1000 is in a falling state according to the current acceleration of the electronic device 1000 detected by the gravitational accelerometer. In the falling state, the anti-drop function is turned on.

However, in practical applications, the downward direction of the gravitational acceleration of the electronic device 1000 does not necessarily mean that the anti-fall function needs to be turned on. Anti-drop function.

Therefore, in order to improve the accuracy of turning on the anti-fall function of the electronic device 1000, the electronic device 1000 of the present application judges whether the electronic device 1000 is in a weightless scene by combining other parameters other than the gravitational acceleration. 1000 state judgment accuracy to avoid false activation of the anti-fall function.

Specifically, in the embodiment of the present application, the electronic device 1000 further includes an antenna assembly 90 , a gravitational accelerometer 100 and a controller 110 .

Wherein, the antenna assembly 90 is used to obtain the communication signal strength of the electronic device, and the antenna assembly 90 is arranged in the casing 10 .

The gravitational accelerometer 100 is used to detect the gravitational acceleration information of the electronic device 1000, and the gravitational accelerometer 100 is arranged in the casing 10;

The controller 110 is connected with the driving assembly 40, the antenna assembly 90 and the gravitational accelerometer 100, and the controller 110 is electrically connected with the antenna assembly 90 and the gravitational accelerometer 100 to control the screen protector 30 to switch between the retracted state and the extended state.

Specifically, referring to FIG. 21 , the controller 110 is electrically connected to the antenna assembly 90 , the gravitational accelerometer 100 and the driving assembly 40 . When the controller 110 determines according to the information collected by the antenna assembly 90 and the gravitational accelerometer 100 that the electronic device 1000 needs to turn on the When the drop function is used, the controller 110 controls the driving assembly 40 to drive the screen protector 30 from the retracted state to the extended state through magnetic force, or, when the controller 110 determines that the electronic device 1000 does not need the information according to the antenna assembly 90 and the gravitational accelerometer 100 When the anti-drop function is turned on, the driving assembly 40 drives the screen protector 30 from the extended state to the retracted state through magnetic force.

It should be noted that the gravitational accelerometer 100 can detect whether the sensing electronic device 1000 is in a falling state. For example, when the electronic device 1000 is in a falling state, the gravitational accelerometer 100 can detect that the gravitational acceleration of the electronic device 1000 is vertical downward, The gravitational acceleration information is transmitted to the controller 110 , and the controller 110 can be connected to the main board 80 in communication. When the controller 110 receives the corresponding gravitational acceleration information, it does not directly judge whether the current electronic device 1000 is in a falling state according to the gravitational acceleration information, but obtains the communication signal strength detected by the antenna assembly 90, and obtains the communication signal connected by the antenna assembly 90. When the signal strength is low, it is considered that the current electronic device 1000 is in a weightless scene such as an elevator, so as to refine the judgment accuracy of the falling state. When the vertical gravitational acceleration value is greater than the improved vertical gravitational acceleration reference value, the electronic device 1000 is considered to be in a falling state. When the acquired communication signal strength connected to the antenna assembly 90 is normal, when the vertical gravitational acceleration of the electronic device 1000 is greater than The reference value of the direct gravitational acceleration, it is considered that the current electronic device 1000 is in a falling state, and the driving component 40 can be controlled to drive the screen protector 30 to switch to the extended state, and the screen protector 30 extends beyond the screen 20 to protect the screen 20, thereby making the screen protector The protection of the screen 20 by the component 30 is more accurate and reliable. For example, when it is detected that the electronic device 1000 is in a falling state according to the information detected by the antenna assembly 90 and the gravitational accelerometer 100 , the controller 110 controls to pass current to the electromagnetic part 41 , so that the electromagnetic part 41 and the permanent magnet 42 are repelled force. Thus, under the action of the magnetic repulsion force, the screen protector 30 is switched from the retracted state to the extended state, and the screen protector 30 extends beyond the screen 20 to protect the screen 20 from falling. Thus, the screen 20 protection function of the electronic device 1000 is automated, and the reliability of the screen 20 protection function of the electronic device 1000 is improved.

In some embodiments of the present application, the controller 110 may control the driving assembly 40 to operate regularly, so as to drive the screen protector 30 to switch back and forth regularly between the retracted state and the extended state. Thereby, the electronic device 1000 can have a massage function. Moreover, the screen protector 30 can be controlled to reciprocate regularly through the controller, and the vibration function of the electronic device 1000 can be implemented.

According to some embodiments of the present application, in order to further improve the accuracy of the fall judgment of the electronic device 1000, the current state of the electronic device 1000 can also be obtained in combination with other sensors, such as a gyroscope, an acceleration sensor, an inertial sensor, a camera, a height sensor, a motion sensor, etc. information. It can be understood that, in order to improve the accuracy and timeliness of the electronic device 1000 for detecting the falling state, a plurality of sensors may be provided in the electronic device 1000 . Therefore, corresponding sensors can be selected according to actual needs, which improves the design diversity of the electronic device 1000 .

In the actual execution process, in order to further avoid misjudgment of the falling state of the electronic device 1000, other sensors can also be combined to judge the current environment of the electronic device 1000:

As a possible implementation manner, as shown in FIG. 22 , the electronic device 1000 may further include at least one light sensor 120 (only one is shown in the figure) electrically connected to the controller 110 , at least one light sensor 120 A part is not blocked by the casing 10 , and at least one light sensor 120 is connected to the casing 10 .

It can be understood that in this embodiment, when the electronic device 1000 is in a weightless environment such as an elevator, the brightness of the environment where it is located is different from the brightness outside the elevator. After entering the elevator, the ambient brightness of the electronic device 1000 has a sudden change. process, in this embodiment, the light sensor 120 detects whether there is such a sudden change in the ambient brightness for the controller 110 to determine whether the current electronic device 1000 is in a weightless scene that is prone to misjudgment. Therefore, the accuracy of judging the falling state is refined, for example, the vertical gravitational acceleration reference value for judging whether the electronic device 1000 is in a falling state is increased, and the vertical gravitational acceleration value of the electronic device 1000 is greater than the improved vertical gravitational acceleration value. The electronic device 1000 is considered to be in a falling state only when the reference value of gravitational acceleration is obtained. When the ambient brightness detected by the light sensor 120 has no sudden change, when the vertical gravitational acceleration of the electronic device 1000 is greater than the vertical gravitational acceleration reference value, it is considered that the current electronic device 1000 In the falling state, the driving assembly 40 can be controlled to drive the screen protector 30 to switch to the extended state, and the screen protector 30 extends beyond the screen 20 to protect the screen 20 . The light sensor 120 can sensitively and accurately detect whether the electronic device 1000 is in a weightless scene where misjudgment is likely to occur, and transmit the corresponding ambient brightness to the controller 110 . The information determines that the current electronic device 1000 is in a falling state, and the screen protector 30 is switched to an extended state to protect the screen 20 from falling, thereby improving the anti-drop performance of the electronic device 1000 .

As a possible implementation, as shown in FIG. 23 , the electronic device 1000 may further include a sound sensor 130 that is electrically connected to the controller 110 , and the sound sensor 130 is connected to the housing 10 .

It can be understood that, in this embodiment, when the electronic device 1000 is in a weightless environment such as an elevator, the environment has sound information consistent with the current scene, for example, there is a floor reminder sound or a reminder sound in the elevator. , by detecting whether the sound sensor 130 has such sound information consistent with the weightless scene, it is judged whether the current electronic device 1000 is in a weightless scene that is prone to misjudgment. , to refine the judgment accuracy of the falling state, such as increasing the reference value of the vertical gravitational acceleration for judging whether the electronic device 1000 is in a falling state, and the electronic device 1000's vertical gravitational acceleration value is greater than the improved vertical gravitational acceleration reference value. The device 1000 is in a falling state, when it is obtained that the sound sensor 130 does not detect sound information consistent with the weightless scene, and when the vertical gravitational acceleration of the electronic device 1000 is greater than the vertical gravitational acceleration reference value, it is considered that the current electronic device 1000 is in a falling state, Therefore, the driving component 40 can be controlled to drive the screen protector 30 to switch to the extended state, and the screen protector 30 extends beyond the screen 20 to protect the screen 20 . Through the sound sensor 130, it can sensitively and accurately detect whether the electronic device 1000 is in a weightless scene that is prone to misjudgment, and transmit the corresponding sound information to the controller 110. If the controller 110 according to the corresponding sound information and gravitational acceleration information It is judged that the current electronic device 1000 is in a falling state, and the screen protector 30 is switched to an extended state, so as to protect the screen 20 from falling, thereby improving the anti-drop performance of the electronic device 1000 .

The electronic device of the embodiment of the present application can prevent the screen from being damaged and improve the anti-drop performance of the electronic device, and at the same time realize the accuracy of the anti-drop start, and avoid the false start of the anti-drop function of the electronic device.

In order to realize the above embodiments, the present application also proposes a control method for an electronic device. FIG. 24 is a flowchart of a control method for an electronic device according to an embodiment of the present application. As shown in FIG. 24 , the method includes:

Step 101: Obtain the communication signal strength of the electronic device through the antenna assembly.

Wherein, the communication signal may be a Wifi signal, a 3G communication signal, a 4G communication signal, etc. According to the different communication signals obtained, the corresponding antenna components are different. For example, when the obtained communication signal is a Wifi signal, the antenna for obtaining the communication signal is Wifi Antenna components, etc. Step 102: Acquire gravitational acceleration information of the electronic device through a gravitational accelerometer.

In the embodiment of the present application, the gravitational accelerometer is a three-axis gravity sensor, and the acceleration in the numerical direction, that is, the acceleration in the Z-axis direction, is calculated by a related calculation method, that is, the gravitational acceleration information. For example, the gravitational acceleration information measured by the three-axis gravity sensor is projected onto the In the Cartesian coordinate system, the acceleration in the Z-axis direction of the Cartesian coordinate system is used as the gravitational acceleration information.

Step 103, when it is determined that the strength of the communication signal is lower than a preset threshold, determine whether the gravitational acceleration information is greater than a default threshold, where the default threshold is a critical value of gravitational acceleration information used to determine whether the electronic device is in a falling state.

Step 104 , when the gravitational acceleration information is greater than the default threshold, control the driving component of the electronic device to drive the screen protector to drive from the retracted state to the extended state.

Among them, the default threshold can be understood as a threshold value that is greater than the reference value of gravitational acceleration for judging whether the electronic device is in a falling state under ordinary circumstances, and the default threshold can be understood as a weightless scene that may be misjudged whether the electronic device is in a falling state. The reference value of gravitational acceleration, where the greater the weightlessness in the weightless scene, the greater the default threshold. In addition, the preset threshold value corresponding to the strength of the communication signal is calibrated according to a large amount of experimental data, and the specific value of the preset threshold value is related to the weightless environment in which it is located.

Specifically, when it is determined that the strength of the communication signal is lower than the preset threshold, it indicates that the current scene is a weightless scene prone to fall misjudgment, so as to determine whether the gravitational acceleration information is greater than the default threshold.

Further, when the gravitational acceleration information is greater than the default threshold value, the driving component of the control electronic device drives the screen protector to drive the screen protector from the retracted state to the extended state. The screen of the electronic device, thus, in a scene where misjudgment of the fall state is likely to occur, the reference value of the judged gravitational acceleration is increased to compensate for the influence of the gravitational acceleration in the weightless scene.

Of course, in order to avoid misjudgments caused by sudden changes in gravitational acceleration information in some application scenarios, it is also possible to perform gravitational acceleration when it is judged that the gravitational acceleration information of the electronic device is downward and lasts longer than a certain period of time, which is consistent with the falling scene. Comparison with the default threshold.

It should be noted that, in order to further protect the screen of the electronic device in the falling state, it is also possible to control the electronic device to be adjusted to the state where the screen is facing upward, for example, by combining hardware devices such as spring buckles and support frames to complete the posture adjustment to control the electronic device. When falling, the screen is farther from the ground to further avoid the impact of the screen.

In the actual execution process, in order to further avoid the misjudgment of the falling state of the electronic device, other sensors can also be combined to judge the current environment of the electronic device:

In an embodiment of the present application, when the electronic device is in a weightless environment such as an elevator, the brightness of the environment where it is located is different from the brightness outside the elevator. After entering the elevator, the ambient brightness of the electronic device has a sudden change. Therefore, in this embodiment, the light sensor detects the current ambient brightness information and the previous moment ambient brightness information, and determines whether the difference between the current ambient brightness information and the previous moment ambient brightness information is greater than a preset threshold, where the preset threshold It varies according to the current environment brightness, for example, the preset threshold value corresponding to the sunny day is smaller than the corresponding preset threshold value of the cloudy sky, and the like.

Further, when it is determined that the difference between the current ambient brightness information and the ambient brightness information at the previous moment is greater than a preset threshold, that is, when the electronic device is in a weightless scene that is prone to misjudgment, the accuracy of the judgment of the falling state is refined, and the gravity is judged. Whether the acceleration information is greater than the default threshold, when the gravitational acceleration information is greater than the default threshold, the driving component of the control electronic device drives the screen protector to drive from the retracted state to the extended state.

When it is determined that the difference between the current ambient brightness information and the ambient brightness information at the previous moment is not greater than the preset threshold, that is, when the electronic device is not in a weightless scene that is prone to misjudgment, it can be determined whether the gravitational acceleration information is greater than the default threshold. When it is determined that the gravitational acceleration information is greater than the default threshold, the driving component of the control electronic device drives the screen protector to drive from the retracted state to the extended state.

In an embodiment of the present application, when the electronic device is in a weightless environment such as an elevator, the environment in which it is located has sound information that matches the current scene, for example, there is a floor reminder sound or a reminder sound in the elevator. In this embodiment, Acquire the sound information of the current environment obtained by the sound sensor, and determine whether the sound information contains target scene identification information. The target scene identification information is the symbolic information corresponding to a weightless scene that is prone to misjudgment. When it is determined that the sound information contains the target scene identification information, it is determined that the electronic device is in a weightless scene that is prone to misjudgment, so as to refine the fall The judgment accuracy of the state, when it is determined that the strength of the communication signal is lower than the preset threshold, it is judged whether the gravitational acceleration information is greater than the default threshold, and when the gravitational acceleration information is greater than the default threshold, the driving component of the control electronic device drives the screen protector to drive from the retracted state to stretched state.

The control method of the electronic device in the embodiment of the present application can prevent the screen from being damaged and improve the anti-drop performance of the electronic device, and at the same time realize the accuracy of the anti-drop start, and avoid the false start of the anti-drop function of the electronic device.

As shown in FIG. 25 , the control device for the electronic device is shown in FIG.
