In some embodiments, the attitude sensor of the protection module is disposed in a vertex angle area of the display surface of the display module.
The attitude sensor used in the present application may be a high-performance three-dimensional motion attitude measurement System based on a Micro-Electro-Mechanical System (MEMS) technology. The system comprises motion sensors such as a three-axis gyroscope, a three-axis accelerometer and a three-axis electronic compass, and data such as a three-dimensional attitude, an azimuth and the like subjected to temperature compensation are obtained through an embedded low-power processor.
In the embodiment of the disclosure, the attitude sensor can be arranged in the vertex angle area of the display surface of the display module, so that the attitude sensor can conveniently detect the attitude of the terminal equipment in the landing process.
When the terminal equipment contacts the ground in different postures after falling, the damage degree of the ground (or objects on the ground) to the terminal equipment is different. For example, one of the corner contact floors of the terminal equipment, especially a very thin terminal equipment, has a terminal of an ultra thin display device. The impact force generated by the ground surface of one corner of the terminal is applied to a point where the terminal is contacted with the ground surface, and under the same impact force, the impact strength of the impact force on the terminal equipment is obviously higher than that when one surface of the terminal is contacted with the ground surface, and the terminal equipment is also more easily damaged. Therefore, in the falling process of the terminal equipment, the posture of the terminal equipment is adjusted to enable the terminal equipment to be more likely to contact the ground in a larger area, so that the action area of the impact force of the ground on the terminal equipment is increased, and the probability of damage of the impact force on the terminal equipment is reduced.
In the process, the adjustment of the attitude of the terminal equipment can be embodied in the angular deflection of the terminal equipment, and the attitude adjustment is realized through the angular deflection. Therefore, the attitude sensor is arranged in the vertex angle area of the display surface of the display module, so that the adjustment condition of the attitude of the terminal equipment can be acquired more conveniently, and the final attitude of the terminal equipment in contact with the ground can be controlled more effectively.

and 41, when the protection module has protection requirements, providing a signal for generating a magnetic field to the coil surrounding the outer side of the pipeline according to the current posture of the equipment, wherein the magnetic fluid in the pipeline changes the distribution position under the action of the magnetic field force provided by the magnetic field.
In the embodiment of the disclosure, the attitude sensor of the protection module can be arranged on the terminal equipment, the protection module and the protected terminal equipment can be integrated, or the protection module can be detachably installed on the terminal equipment, so that the attitude sensor can detect the attitude of the terminal equipment in the descending process.
In the embodiment of the disclosure, the specific vertical downward acceleration when the terminal device falls is determined, and the detected posture of the device is not the preset posture, so that the device in the state can be determined to be protected, and the protection module has protection requirements. The preset posture is a preset required posture which needs to be adjusted to, namely a posture which can ensure that the terminal equipment is in a safe state when contacting the ground or an object contacting the ground.
In the embodiment of the disclosure, the posture can be understood as a relative position relationship between the terminal device and the ground, and specifically, a three-dimensional direct coordinate system can be established, and the three-dimensional direct coordinate system is embodied by a coordinate position of the terminal device in the coordinate system. The three-dimensional direct coordinate system may have a coordinate origin at a central point of the terminal device. The coordinate planes of the three-dimensional rectangular coordinate system have a constant corresponding relationship with the ground, for example, the coordinate system is O-XYZ, and if the XOY plane is parallel to the ground, that is, the three-dimensional rectangular coordinate system always uses the central point of the terminal device as the origin no matter where the terminal device is located in the space during the landing process (i.e., no matter where the terminal device is located relative to the ground), the XOY plane is always parallel to the ground.

Fig. 6 is a schematic diagram of magnetic fluid flow during attitude adjustment of a terminal device according to an exemplary embodiment. As shown in fig. 6, when the terminal device is adjusted from the current posture to the preset posture, the direction and the magnetic field strength of the magnetic field generated by the coil are controlled by controlling the magnitude and the direction of the signal (generally, current) of the coil surrounding each pipe, so as to control the flow direction and the flow speed of the magnetofluid in each pipe, further influence the rotation direction and the rotation angular speed of the terminal device on each coordinate axis, and the rotation angle of the terminal device on each coordinate axis can be obtained by differentiating the rotation angular speed in time, so as to finally realize the posture adjustment. In the case of 4 tubes as shown in fig. 4, the signal of the coil on each tube is controlled separately to drive the flow of the magnetic fluid in each tube separately. Under the coordination of magnetic fluid flowing in each pipeline, the distribution condition of the magnetic fluid is integrally changed, so that the centroid position of the terminal equipment is moved to a new centroid position from the original centroid position, and under the action of universal gravitation, the angular deflection of the terminal equipment is realized.
In some embodiments, the preset posture is a posture in which a maximum-area surface of the protection module faces a preset direction;
the method further comprises the following steps:
and changing the distribution position of the magnetic fluid in the pipeline, changing the mass center of the terminal equipment and enabling the terminal equipment to present the preset posture.
Fig. 7 is a schematic diagram illustrating a posture of the terminal device when the terminal device is landed after the posture adjustment according to an exemplary embodiment. As shown in fig. 6, since the protection module and the terminal device may be integrated or fixed to the terminal device, the position of the center of mass of the terminal device may be changed after the magnetic fluid flows in the pipeline under the action of the magnetic field force. In the falling process of the terminal, under the action of universal gravitation, the terminal deflects at an angle, so that the terminal equipment can have the posture that the surface with the largest area faces the preset direction when reaching the ground, and the damage to the terminal equipment, which is possibly caused by the ground or the table top when the terminal equipment contacts the ground or the table top, is reduced as far as possible.
In some embodiments, the determining whether the protection module has a protection requirement according to the gesture detected by the gesture sensor includes:

In the embodiment of the disclosure, when the terminal device contacts the ground in different postures after being dropped, the damage degree of the ground (or objects on the ground) to the terminal device is different. When one angle of the terminal contacts the ground, the impact force generated by the terminal and the ground acts on a point where the terminal is contacted with the ground, and under the same impact force, the impact strength of the impact force on the terminal equipment is obviously higher than that when one surface of the terminal is contacted with the ground, and the terminal equipment is easily damaged. Therefore, the posture of the maximum area surface of the terminal when contacting the ground can be taken as the preset posture, and other situations that the damage to the terminal equipment when contacting the ground may be larger than the preset posture can be considered as the state needing protection. The terminal device falling judging method comprises the steps of determining that the terminal device has acceleration in a preset direction, specifically vertical downward gravity acceleration, starting a protection function of the protection module on the terminal device, and adjusting the posture of the terminal device.
In the embodiment of the present disclosure, the preset direction is a preset moving direction of the terminal device, and may include a vertical direction toward the center of the earth; or the like, or, alternatively,

The vertical direction towards the center of the earth is the acceleration direction towards the center of the earth (including free fall or parabolic motion at a certain initial speed) when the terminal device falls, under the action of the gravitational force.
The maximum acceleration direction when the terminal device is not held is the overall acceleration direction of the overall stress when the terminal device moves, for example, the terminal device moves towards a certain preset direction under the stress to reach a preset position, and at the moment, the posture of the terminal device can be adjusted, so that the terminal device can have the posture that the surface with the largest area faces the preset direction when reaching the preset position, and the damage to the terminal device caused by the ground or the table board at the preset position when the terminal device contacts the ground or the table board at the preset position is reduced as much as possible. For example, a terminal device on an inclined staircase or acted on by an object may be popped up or slid out under the combined action of gravity or the acted object (e.g., a spring or a supporting surface with elasticity), and at this time, the direction of the maximum acceleration of the terminal device may be different from the vertical direction toward the center of the earth.
In the embodiment of the disclosure, when the terminal device is applied specifically, the terminal device falls in the process, the terminal gesture can be adjusted in a multi-cycle manner according to the situation, whether the gesture of the terminal device is adjusted in place or not is monitored in real time, so that the bottom surface of the terminal is contacted with the ground in the largest area as far as possible, the probability that a weak device is contacted with the bottom surface and damaged is reduced as far as possible, the probability that the screen and the glass rear cover are damaged is reduced, the reliability of the terminal device is enhanced, the battery play in a machine cabin is reduced, the impact between the battery and the periphery is reduced, the vibration of the terminal protection board is reduced, the connector loosening probability is reduced, the terminal middle frame is protected, and the probability that the middle frame is rubbed and damaged is reduced.
Fig. 8 is a flowchart illustrating a second method for posture adjustment based on a protection module according to an exemplary embodiment. As shown in fig. 7, after the terminal device falls, the whole protection process of the protection module on the terminal device is as follows:
after the terminal equipment falls down, the attitude sensor identifies the attitude of the terminal equipment;
when the protection requirement is determined (namely the terminal equipment needs to be subjected to posture adjustment), transmitting the posture data of the current posture of the terminal equipment to the controller;
controlling the current posture and the preset posture based on the terminal equipment, acquiring posture adjustment information, and acquiring a signal (generally current) to be output to the coil based on the posture adjustment information;
the coil generates a magnetic field under the action of a signal to control the flow of the magnetofluid in the pipeline;
the change of the position of the center of mass of the terminal is finally realized through the flow of the magnetic fluid, so that the posture of the terminal equipment is changed;
the attitude sensor acquires the attitude of the terminal equipment again, and if the attitude meets the preset attitude, the adjustment is finished; otherwise, the steps are installed and adjustment is continued until the preset posture is met.
