All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described are capable of operation in sequences other than those illustrated or otherwise described herein.

Moreover, the terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not expressly listed or inherent to such process, method, article, or apparatus.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

For convenience of understanding and explanation, the automatic falling position adjusting protective shell, the device and the protection method based on the magnetic slider provided by the embodiment of the application are explained in detail through fig. 1 to 5.

Please refer to fig. 1, which is a schematic diagram of a basic structure of an automatic falling position adjusting protective case based on a magnetic slider according to an embodiment of the present application. The protective shell 100 is provided with a magnetic slider member 101 and a slide rail 102, and the magnetic slider member 101 moves on the slide rail 102 according to a control command of the fall monitoring device 103.

For example, as shown in fig. 2, a schematic structural diagram of an automatic falling position adjusting protective housing based on a magnetic slider according to an embodiment of the present application is provided. Assuming that the protective case 100 has a quadrangular shape, it can be seen that a slide rail 102 is provided around the edge of the protective case 100, and magnetic slider members 101 are provided on both ends of at least one diagonal line of the slide rail 102, respectively. The magnetic slider member 101 includes a magnet slider 1011, a vertical flap 1012 and a horizontal flap 1013, and the vertical flap 1012 and the horizontal flap 1013 are configured to be opened and closed according to a control command of the fall monitoring device 103 to limit the moving direction of the magnet slider 1011.

Of course, in the embodiment of the present application, the magnetic slider members 101 may be disposed on both ends of two diagonal lines of the slide rail 102. Fig. 3 is a schematic structural diagram of another automatic falling position adjusting protective case based on a magnetic slider according to an embodiment of the present application. Because the four corners of the protective shell 100 are provided with the magnetic slider members 101, controllable force is more comprehensive, the state of the electronic device when falling to the ground can be accurately changed, and the risk of screen breaking caused by edge contact with the ground is avoided.

Optionally, the combination of the magnetic slider member 101 and the sliding rail 102 in the embodiment of the present application may include, but is not limited to, suspension, penetration, or snap. Specifically, levitation refers to a way in which the magnetic slider member 101 is attracted to the surface of the slide rail 102 when not moving, and is not in contact with the surface of the slide rail 102 when moving, such as magnetic levitation; throughout means that the slide rail 102 passes through the center of the magnetic slider member 101; snap refers to the way that the portion of the magnetic slider member 101 and the sliding rail 102 that are in contact are mating mechanical structures, such as train wheels and rails.

Optionally, a fall monitoring device 103 is disposed on the protective shell 100 in the embodiment of the present application, and the fall monitoring device 103 includes a microprocessor and an acceleration sensor. It should be noted that, the fall monitoring device 103 may also be disposed on the electronic device, that is, the protective case 100 shares the fall monitoring device 103 of the electronic device. Specifically, the acceleration sensor in the fall monitoring device 103 may include, but is not limited to, any one of a piezoelectric acceleration sensor, a piezoresistive acceleration sensor, a capacitive acceleration sensor, or a servo acceleration sensor. By using the acceleration sensor, the falling state of the electronic apparatus can be detected, thereby facilitating control of the moving direction of the magnetic slider member 101 on the protective case 100. For example, when the electronic device is in a static state, the reported data of the acceleration sensor is 0, 9.8, and when the electronic device is in a free-fall state, the reported data of the acceleration sensor is 0, thereby completing the detection of the fall state of the electronic device.

Optionally, the fall monitoring device 103 in this embodiment of the present application further includes a gyroscope sensor. Specifically, the gyro sensor may include, but is not limited to, any one of a two-degree-of-freedom gyro sensor or a three-degree-of-freedom gyro sensor. For example, the offset of the electronic device from the reference coordinate system is obtained by the gyro sensor, so as to determine whether the electronic device faces the ground. The gyroscope sensor is actually equivalent to three angle sensors, and because a 3D reference coordinate system exists in the electronic equipment, when the coordinates of a chip in the gyroscope deflect relative to the reference coordinates, the chip can acquire the change, so that the deflection quantity of the electronic equipment in the directions of an x axis, a y axis or a z axis is acquired. Therefore, the falling state of the electronic device can be detected more accurately by using the acceleration sensor and the gyroscope sensor in a combined manner, so that the movement direction of the magnetic slider member 101 on the protective shell 100 is accurately controlled, the controllable force is more comprehensive, and the edge of the electronic device is prevented from touching the ground.

The operation principle of the protective case 100 in the embodiment of the present application will be described below with reference to fig. 3 as an example. After the fall monitoring device 103 detects the fall state of the electronic device, assuming that the point a of the electronic device is close to the ground, the electronic device is subjected to downward gravity to perform free fall movement, and at this time, an upward force needs to be applied to the electronic device to change the fall state of the point a with the edge touching the ground, for example, a microprocessor in the fall monitoring device 103 controls to open a vertical movable baffle 1012 of the point a magnet slider 1011, so that the magnet slider 1011 can move toward the point B along the slide rail 102.

The automatic position control protective housing that falls based on magnetism slider that this application embodiment provided is provided with magnetism slider component and slide rail on this protective housing, and magnetism slider component moves on the slide rail according to the control command that falls monitoring devices. This application is when falling monitoring devices and detecting that electronic equipment is falling, through the direction of motion of the magnetic slider component on the slide rail that control command control protective housing set up, produces the power opposite with this electronic equipment direction of falling from this to automatically, changed this electronic equipment's the state of falling to the ground, effectively avoided the edge to touch to ground the screen that causes cracked.

Those skilled in the art will appreciate that the configuration shown in fig. 4 does not constitute a limitation of electronic device 401, and may include more or fewer components than shown, or combine certain components, or employ a different arrangement of components.

The electronic equipment provided by the embodiment of the application comprises the automatic falling position adjusting protective shell based on the magnetic slider and a falling monitoring device arranged on the electronic equipment. When the falling monitoring device detects that the electronic equipment falls, the movement direction of the magnetic slider component arranged on the protective shell on the sliding rail is controlled through the control command, so that a force opposite to the falling direction of the electronic equipment is generated, the falling state of the electronic equipment is automatically changed, and screen fragmentation caused by edge contact with the ground is effectively avoided.

Based on the foregoing embodiments, an embodiment of the present application provides a method for protecting an electronic device. As shown in fig. 5, the electronic device protection method is used in an electronic device 401, and includes the following steps:

s501, acquiring acceleration change values of the electronic equipment in all directions, which are acquired by the falling monitoring device.

For example, when the electronic device 401 is in a stationary state, three direction data of an x axis, a y axis, and a z axis reported by the acceleration sensor are 0, and 9.8, respectively, and when the electronic device 401 is in a free-fall state, the reported data of the acceleration sensor is changed to 0, and 0, at this time, the acceleration change values in the x axis and the y axis are both 0, and the acceleration change value in the z axis is 9.8.

And S502, when the acceleration change value in the direction is larger than or equal to a preset threshold value, the falling monitoring device sends out a command for controlling the magnetic slider component to move along the sliding rail in the direction opposite to the direction.

For example, assuming that the preset threshold is 9.8, since the acceleration variation value of 9.8 in the z-axis direction is equal to the preset threshold at this time, it indicates that the electronic device 401 has a large movement in the z-axis direction. Thus, the fall monitoring device 103 issues commands to control the movement of the magnetic slider member 101 along the slide rail 102 in the direction opposite to the z-axis direction to avoid the risk of screen breakage due to the edge of the electronic device 401 touching the ground.

When the protection process of the electronic device 401 is implemented, for example, the magnetic slider 101 may be connected to the power supply 4017 of the electronic device 401 through a switch, the switch may be controlled by a command from the microprocessor 4011 in the fall monitoring apparatus 103, and the moving speed of the magnetic slider 101 along the sliding rail 102 may be adjusted by the magnitude of the current. Of course, the switch may also be a movable baffle in the magnetic slider member 101, that is, the vertical movable baffle 1012 and the horizontal movable baffle 1013, and the vertical movable baffle 1012 and the horizontal movable baffle 1013 can be opened and closed according to the control instruction of the fall monitoring device 103 to limit the moving direction of the magnetic slider 1011 in the magnetic slider member 101, thereby enriching the protection mode of the electronic device.

According to the electronic equipment protection method provided by the embodiment of the application, the falling state of the electronic equipment is detected by comparing the acceleration change values of the electronic equipment in all directions, which are acquired by the falling monitoring device, with the preset threshold value. When the acceleration change value in a certain direction is larger than or equal to the preset threshold value, the edge in the direction is indicated to touch the ground, and at the moment, the falling monitoring device sends a command for controlling the magnetic slider component on the protective shell to move along the sliding rail in the direction opposite to the direction based on the automatic falling position adjustment of the magnetic slider, so that a force opposite to the falling direction of the electronic equipment is generated, the falling state of the electronic equipment is automatically changed, and screen fragmentation caused by the edge touching the ground is effectively avoided.

Based on the foregoing embodiments, the present application further provides a non-transitory computer-readable storage medium comprising instructions, such as the memory 4012 comprising instructions, which are executable by the microprocessor 4011 of the electronic device 401 to implement the electronic device protection method.
