With the development of mobile terminal technology, mobile terminals have become an indispensable tool for people. In order to cater to the needs of consumers, manufacturers and developers of mobile terminals are increasingly emphasizing the visual impact of human-computer interaction interfaces, so manufacturers and developers are making screens of mobile terminals bigger and bigger, touch screens and displays. The screen fits more and more tightly, the frame becomes narrower and narrower (the screen ratio is getting larger and larger), the battery capacity is getting larger and larger (the endurance is enhanced). With the improvement of these performances, the anti-drop performance of mobile terminals is becoming weaker and weaker. Therefore, the anti-drop performance of mobile terminals becomes more and more important.

When the mobile terminal accidentally landed, the most deadly damage is the LCD (Liquid Crystal Display) and the four corners of the LCD, and in many cases the edge of the LCD is damaged and the LCD is broken. However, if the mobile terminal is level-balanced, the probability of the LCD and its corners being broken is much smaller, and the damage of the mobile terminal is also much smaller when the casing of the mobile terminal is grounded.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.

Referring to FIG. 1 , a drop prevention device 10 according to an embodiment of the present invention is shown. The anti-fall device 10 can be applied to a mobile terminal, such as a smart phone, a tablet computer, a personal digital assistant (PDA, Personal Digital Assistant), and the like. . In a specific implementation process, the anti-drop device 10 can be designed as an edge portion of the mobile terminal to become an integral part of the mobile terminal; or can be designed as an edge casing of the mobile terminal to be coupled with the mobile terminal. In the embodiment of the present invention, the technical solution is described by taking the anti-drop device 10 as an edge portion of the mobile terminal, thereby becoming an integral part of the mobile terminal. It can be understood that the person skilled in the art can apply the anti-drop device 10 to the frame designed as a mobile terminal to be coupled with the mobile terminal according to the technical solution of the embodiment of the present invention.

As shown in FIG. 1 , the anti-drop device 10 may include: a state detecting module 101, a drop control module 102, a drop protection module 103, a motor group module 104, and a center of gravity adjustment module 105;

The state detecting module 101 is configured to determine, according to the collected sensor data of the mobile terminal, that the mobile terminal is in a falling state, and transmit the falling state value corresponding to the falling state of the mobile terminal to the drop control module 102;

The anti-drop control module 102 is configured to generate an attitude adjustment command and an adjustment parameter according to the falling state value of the mobile terminal and the preset anti-drop strategy, open the anti-drop protection module 103, and transmit the posture adjustment command and the adjustment parameter to the defense Fall protection module 103;

The drop protection module 103 is configured to control the working states of the motor group module 104 and the center of gravity adjustment module 105 according to the preset control strategy and the attitude adjustment command and the adjustment parameters, and adjust the position of the center of gravity and the falling posture when the mobile terminal is dropped.

Understandably, when a mobile terminal, such as a mobile phone, is dropped, the location of the location is mainly caused by the external force before the mobile phone is thrown, the instantaneous state when the mobile phone is dropped, the center of gravity of the mobile phone, and the landing hand. The horizontal or vertical state of the machine or other azimuth angles are determined. Therefore, the basic idea of the embodiment of the present invention is that by adjusting the state of the falling moment of the mobile phone, the posture in the falling process can change the grounding state before the mobile phone falls. And when the mobile phone is landing, the instantaneous landing speed will be very large. If it is in contact with the hard ground, the instantaneous impact will cause the mobile phone to be damaged. If the landing speed slows down, the hard landing will become a soft landing, and the impact damage will be reduced. Fall protection.

It can be known from the above basic idea that if the result of the fall of the mobile terminal is that the back shell is landing and landing horizontally, it is possible to avoid damage or cracking of the mobile terminal due to the corners. Therefore, the working principle of the anti-drop device shown in FIG. 1 is to control the working state of the motor group module 104 and the center of gravity adjustment module 105 through the drop protection module 103, thereby realizing that the rear shell is grounded and horizontally landed when the mobile terminal is dropped.

Illustratively, the sensor data of the mobile terminal may include gravity acceleration detected by the acceleration sensor existing by the mobile terminal itself, x-axis, y-axis, z-axis acceleration and angular velocity detected by the three-axis gyroscope, and the light sensor. The amount of light detected. Therefore, the state detecting module 101 can be specifically used to:

When the acceleration sensor detects that the current vertical downward acceleration of the mobile terminal is gravitational acceleration, it is confirmed that the mobile terminal is in a falling state;

When the mobile terminal is in a falling state and the three-axis gyroscope detects that the current angular rate change value of the mobile terminal exceeds a preset first threshold, confirms the tilt value in the upward direction of the mobile terminal during the falling process, and drops the mobile terminal The inclination value in the respective directions is transmitted to the drop control module 102; and,

When the mobile terminal is in a falling state and the light sensor amount reduction value detected by the light sensor exceeds the second threshold, it is confirmed that the LCD face is facing down during the falling of the mobile terminal, and the information of the LCD face down in the process of dropping the mobile terminal is transmitted to the defense. Drop control module 102.

It should be noted that the tilt value of the mobile terminal in the upward direction during the falling process can represent the tilt state of the mobile terminal during the falling process, such as tilting left and right, or tilting up and down. Various tilting states of the vertical falling process;

Specifically, the state detecting module 101 can collect the current acceleration, angular rate data, and the like of the mobile terminal in real time, and perform corresponding calculation and conversion. If the acceleration or angular velocity is regularly changed, it can be matched with the typical motion model parameters pre-stored in the state detecting module 101, and the falling state of the mobile terminal can be thrown, thrown, thrown, and other external forces. The non-free fall motion is caused to make an accurate judgment, and the collected state value is transmitted to the anti-drop control module 102 to discriminate whether it is in an abnormal state, and corresponding drop control is performed on different drop states. To adjust the mobile phone landing status.

In addition, the amount of light sense detected by the light sensor can be used to indicate whether the LCD surface is landing during the falling of the mobile terminal or the back shell surface is landed. For example, when it is detected that the amount of light sensitivity is drastically decreasing, it indicates that the LCD face is falling downward; when it is detected that the amount of light perception is almost unchanged, it indicates that the back shell faces downward.

In the specific implementation process, taking a mobile phone as an example, in a natural light or lighting environment, the light sensing device at the top of the LCD surface of the mobile phone passes through the structural opening, when the LCD surface faces up and down, due to the light surface and the light protection The difference in the surface, the amount of light received by the light sensor will be significantly different. Therefore, by intermittently collecting the light sensitivity values in different time periods and environments, and then storing them in the register of the mobile phone state detection module as the first light sensitivity value; when detecting that the mobile phone is in a falling state, the light sensing device collects the falling process. The value of the light sensitivity in the second light sensitivity value; by comparing the difference between the two values, and simultaneously detecting whether the second light sensitivity value is exponentially decreased as the grounding distance decreases, and the index coefficient is passed The pre-tested parameter model is directly called, and its parameter model is tested by different levels of light perception and ground distance in the laboratory environment, and then the ground light perception change parameter model is established. Since the amount of light perception decreases with the approaching distance to the ground when the LCD is facing up, that is, the light sensing device is facing upward, the reduction is not sharply reduced, and the index mode is not sharply decreased. Therefore, it can be clearly distinguished from the case where the LCD face down. In the detection process in the state detection model, the error detection can be avoided by further judging the processing, specifically, the parameter model collected in the laboratory environment is mainly Distinguish the difference between the two.

Further, if the outdoor ambient light is relatively poor, or the indoor dark environment, the light perception cannot be effectively detected by the external light source to determine whether the mobile phone LCD is facing downward or the rear casing is facing downward. At this time, when detecting that the mobile phone is in a falling state, the anti-drop control module 102 can immediately control the mobile phone to turn on its own flash continuously, provide a continuous light source for the detection of the light sensor, and then continue the light sensing to determine the current mobile phone. Orientation.

Illustratively, after the fall prevention control module 102 acquires the drop state value of the mobile terminal, the gesture adjustment may be performed for the mobile terminal according to the drop state value of the mobile terminal, and the corresponding posture adjustment command and the adjustment parameter are generated, and the posture adjustment is performed. The command and the adjustment parameter are transmitted to the drop protection module 103, so that the drop protection module 103 can control the working state of the motor group module 104 and the center of gravity adjustment module 105 according to the posture adjustment command and the adjustment parameter, thereby adjusting the movement when the mobile terminal is dropped. Center of gravity and falling posture.

The anti-drop device 10 shown in FIG. 2 is applied to the structure of the mobile terminal. In a preferred implementation, the motor group module 104 includes at least two vibration motors, as shown by the circle marked with M in FIG. Preferably, the vibration motor included in the motor group module 104 may be disposed at a corner position corresponding to the mobile terminal.

The center of gravity adjustment module 105 may include a gravity block 1051 disposed in the sliding cavity 1052 at an edge position corresponding to the mobile terminal, and connected to the vibration motor in the motor group module 104 via a connecting line, as shown by the hatched square in FIG. It can be understood that the sliding cavity 1052 is a track for the sliding block 1051 to slide, and can be disposed on the edge of the corresponding housing of the mobile terminal, and specifically can be a plastic hollow cavity, and the gravity block 1051 can move quickly in the hollow cavity. The sliding cavity 1052 may be provided as at least one set of vertical or horizontal directions of the mobile terminal, or may be set to be two sets of vertical and horizontal directions, as shown by the dashed box surrounding the diagonal square in FIG. In this embodiment, the four vibration motors shown in FIG. 2 and the corresponding four gravity blocks 1051 are taken as an example, and the technical solution is not limited. Preferably, the gravity block 1051 can be made of a substance having magnetic properties; correspondingly, an electromagnetic relay unit 1053 made of a semi-magnetic material is disposed around the periphery of the sliding cavity 1052, as shown in FIG. The dot fill box is shown. When the mobile terminal is in the normal use state, the electromagnetic relay unit 1053 is in a power-on state, has magnetic properties, and the gravity center block is attracted by the electromagnetic relay unit 1053, is in a relatively fixed state, and the rotor of the vibration motor and the center of gravity block are non-linear. When the mobile terminal is in a falling state, the electromagnetic relay unit 1053 is powered off, the electromagnetic relay unit 1053 is in a power-off state, and then the magnetic force is lost, the attraction force of the gravity block 1051 is weakened, and the vibration motor rotates. Under the pulling, the connecting line is straightened, and then the gravity block 1051 moves in the sliding cavity 1052 until the vibration motor stops, the electromagnetic relay unit 1053 is energized, and the gravity center block is attracted by the electromagnetic relay unit 1053, and is again in a relatively fixed state.

Further, in the anti-drop device 10, the attitude adjustment command and the adjustment parameter for controlling the working state of the motor group module 104 can be specifically used to control the running direction of the vibration motor in the motor group module 104, such as forward running and reverse running; It can also be used to control the running amplitude of the vibration motor in the motor group module 104, such as small deflection, large-scale centrifugal motion; and can also be used to control the operating speed of the vibration motor in the motor group module 104, such as slow speed, medium speed and high speed; It can also be used to control the running time, step value and the like of the vibration motor in the motor group module 104.

The attitude adjustment command and the adjustment parameter for controlling the working state of the center of gravity adjustment module 105 can be specifically used to adjust the running number of one or more sets of vibration motors in the motor group module 104, and the sliding direction of the gravity block 1051 of the center of gravity adjustment module 105. Make adjustments to adjust the center of gravity of the mobile terminal in a balanced direction. The above-described adjustment sliding direction may include lateral movement, or longitudinal movement, or flexible movement in four directions of up, down, left, and right.

It can be understood that the anti-drop control module 102 can complete the above control by controlling the software code instruction of the motor group module 104 to complete the specific customized detail parameter modulation by changing different motor drive commands and parameters. At the same time, the torque generated by each parameter adjustment and the parameter mode of the running direction are pre-established and stored in the drop protection module 103. In a specific implementation process, the drop control module 102 compares the drop state value of the mobile terminal currently detected by the state detecting module 101 with the preset target balance state model, and calculates a corresponding posture adjustment finger. And the parameter is adjusted; the anti-drop protection module 103 performs corresponding adjustment control by the opening of the anti-drop control module 102 and the attitude adjustment command and the adjustment parameter of the transmission, until the state detecting module 101 detects that the mobile phone is safely landing according to the target equilibrium state model.

It should also be noted that when the outer casing of the mobile terminal is subjected to reinforcement and anti-drop treatment in a certain part, the target balance state model of the mobile phone may be set to be in the corresponding direction in which the position after the anti-drop treatment is performed, and the anti-drop protection module 103 controls the falling process and the moving direction of the mobile terminal, so as to finally land the portion after the strengthening or anti-drop treatment, thereby protecting the mobile terminal and avoiding damage to other parts.

In summary, the specific structure and working principle of the motor group module 104 and the center of gravity adjustment module 105, preferably, the specific process of the anti-drop control module 102 to generate the attitude adjustment command and the adjustment parameter may be:

The anti-drop control module 102 is specifically configured to:

When it is determined that the current drop state of the mobile terminal is a slight imbalance according to the drop state value of the mobile terminal, an instruction and a motion parameter for indicating the eccentric motion of the vibration motor in the motor group module 104 are generated to pass the vibration motor in the motor group module 104. The eccentric torque to achieve fine-tuning of the phone imbalance. Specifically, when the vibration motor is in operation, the eccentric wheel on the rotating shaft of the vibration motor also rotates together, and since the center point of the eccentric wheel is not at the center of the vibration motor, the vibration motor is in a state of constant loss of balance. Vibration, thereby vibrating the motor for eccentric motion. When specifically implemented, during the fall, when the state detecting module 101 detects the tilt caused by the slight imbalance of the mobile terminal, the drop protection module 103 can initiate a resonance balancing mechanism to control the motor group module 104 in the corresponding imbalance direction. When the operation is large, the eccentric wheel on the motor shaft will rotate together, and since the center point of the eccentric wheel is not at the center of the motor, the motor will vibrate in a state of constant loss of balance, and the torque generated by the vibration is not only You can change the center of gravity of the current phone, and the torque of the two sets of corresponding directions can also return the phone to balance.

When determining the current drop state of the mobile terminal as the mobile terminal according to the drop state value of the mobile terminal When the center of gravity of the end is unbalanced, commands and parameters are generated for instructing the vibration motor in the motor group module 104 to control the movement of the gravity block 1051 in the center of gravity adjustment module 105, so that the center of gravity adjustment module 105 connected thereto is driven by the vibration motor rotation. The gravity block 1051 restores the center of gravity of the mobile terminal to the target equilibrium state. Specifically, the commands and parameters for indicating the vibration motor in the motor group module 104 to control the movement of the gravity block 1051 in the center of gravity adjustment module 105 may include the rotational speed, amplitude, number of revolutions, and steps of the vibration motor in the motor group module 104. Value and so on. In a specific implementation, the direction in which the movement of the gravity block 1051 in the gravity center adjustment module 105 is controlled may be a lateral movement of the gravity block 1051 on the edge region of the mobile terminal, or may be a longitudinal movement on the edge region, or may be up and down. Flexible movement in four directions,

During the operation of the center of gravity adjustment module 105, a set of motors may simultaneously drive the horizontal and vertical gravity blocks 1051 in the edge housing of the mobile terminal, or two sets of motors respectively drive the horizontal gravity block 1051 and the longitudinal gravity block 1051 in the mobile phone. . The position of the motor can be located in the four corners of the mobile phone as shown in the figure. The number of motors and the specific position can be flexibly selected due to the layout design of the mobile phone. The gravity block 1051 can be a light weight gravity adjustment block, which can reach a certain degree of torque by the growth of the force arm, or can be a heavy mass gravity adjustment block, so that the torque of the same effect can be moved within a short distance. The gravity adjustment mode may be that one set of motors is directly pulled, one is pulled by another, or may be magnetically adjusted. When the mobile phone is in a falling state, the electromagnetic relay circuit is powered off, and the center of gravity adjustment module 105 is unattractive. In the movable state, when the center of gravity balance is adjusted in place, the electromagnetic relay circuit starts the power supply, and the magnetic gravity block 1051 is adsorbed and fixed at the current position.

It should be noted that, in order to be able to assist in adjusting the position of the center of gravity and the falling posture when the mobile terminal is dropped, and to perform buffering during landing, as shown in FIG. 3, the above-mentioned anti-drop device 10 may further include: for placing the motor group module 104. The open-hole sealing cavity 106 of the middle vibration motor is used to control the falling posture of the mobile terminal when it is dropped by the recoil force of the compressed airflow generated by the high-speed rotation of the vibration motor in the motor group module 104, as shown by the chain line frame in FIG. And, when the mobile terminal is close At the time of the ground, the compressed airflow generated by the high-speed rotation of the vibration motor in the motor group module 104 forms an air protective layer on the ground to buffer the landing of the mobile terminal.

Specifically, when the motor is used as a conventional vibration device, the motor speed and steering are fixed, and the rotation speed is low and the duration is short. When the motor needs to rotate at a high speed, the conventional power supply of the control motor can be converted into a high voltage power supply by the variable voltage LDO. When the motor is under high voltage power supply, the rotation speed can be greatly increased instantaneously, and a continuous airflow of a certain intensity is generated, and the air flow can be One strand can also be two strands in the same clock direction, or four strands in the same clock direction. The recoil force of the thrust combination of these airflows changes the current fall state of the mobile terminal until the horizontal balance falls. For example, taking a mobile phone as an example, if the top of the mobile phone is on a horizontal plane, one or two sets of motors at the bottom of the mobile phone can be started to run at a high speed, and a high-speed airflow is generated to the bottom hole of the rear case, and the bottom of the mobile phone is lifted by the reverse thrust of the airflow. Above the horizontal plane, the motor at the top of the mobile phone can be activated at the same time to generate high-speed airflow, and the high-speed airflow is sprayed to the top of the front shell. The reverse thrust of the airflow pushes the top of the mobile phone down, and the bottom of the mobile phone returns to a horizontal plane. In addition, it is also possible to combine the above two types, and the top airflow and the bottom airflow work in opposite directions to achieve the purpose of rapidly changing the falling state of the mobile phone. Similarly, when the mobile phone is left and right unbalanced, the current left and right imbalance state of the mobile phone can be reversed by turning on the left or right side or the left and right side reverse air holes and the recoil force of the high speed compressed air flow generated by the motor.

At the same time, when the mobile phone crashes to contact the ground, the anti-drop protection module 103 simultaneously opens four air holes in the bottom direction of the mobile phone, and the motor drives the rotor to generate a high-speed compressed airflow to generate a gas flow protection layer on the ground, which acts as an air cushioning and landing. . Specifically, there may be multiple working modes, such as starting the opening time point by the speed detection in the vertical direction, and monitoring the falling speed or the falling time of the mobile phone in real time, and indicating the current falling height when the speed or the falling time is greater than a certain threshold. Exceeding the safe range, the impact on the ground is very large, and the continued fall will cause relatively large damage. At this time, the grounding buffer mechanism in the drop protection module is opened, and the air impulse generated by the high speed motor buffers the landing speed while the speed is from The maximum time to 0, so the mobile phone impulse to the ground will be greatly reduced.

It can be understood that the vibration motor in the motor unit module 104 can perform the high-speed rotation through the anti-drop protection module 103 by performing the attitude adjustment command and the adjustment parameter generated by the anti-drop control module 102, thereby generating a compressed airflow in the aperture sealing cavity 106. Moreover, controlling the falling posture of the mobile terminal when it is dropped by the recoil force of the compressed airflow is generally only applicable to the adjustment of the slight unbalanced state of the mobile terminal.

In addition, in order to prevent the accidental triggering of the anti-drop device 10, referring to FIG. 4, the anti-drop device 10 may further include an anti-false trigger module 107 for collecting the working state of the mobile terminal; and when the working state of the mobile terminal satisfies the preset When the condition is ignored, the function of the anti-drop control module 102 is turned off. For example, when the mobile terminal is in a running state in which the pedometer is turned on, or in the up and down state, the function of the anti-drop control module 102 is turned off; or the user can also turn off the anti-drop control module 102 in advance in the above-mentioned motion state. The function is turned off.

Specifically, when the proximity detecting or sensing circuit is built in the mobile terminal, the error prevention triggering module 107 can also automatically turn off the state detecting module 101 by detecting whether the mobile terminal is in the state of holding the hand. For example, when the pressure sensor in the pressure screen detects that the mobile terminal is in the hand, or the screen detects the pressure of the human hand, if the acceleration of the mobile terminal is detected to be abnormal at this time, the drop protection module 103 does not need to be opened. When the human hand pressure is not detected, the corresponding drop protection module 103 is activated.

Moreover, referring to FIG. 4, the anti-drop device 10 may further include a self-balancing calibration module 108 for acquiring a balanced landing state of the mobile terminal. Specifically, the self-balancing calibration module 108 can adjust the center-of-gravity adjustment module 105 of the mobile terminal to a central symmetric position according to the position of the center of gravity of the mobile terminal, so that the mobile terminal can be in a self-balancing state when the mobile terminal is free to fall in the horizontal direction. In a preferred implementation process, after receiving the calibration command issued by the user, the self-balancing calibration module 108 prompts the user to make a free landing and short-distance falling body, and according to the foregoing scheme, according to the state of the state detecting module 101 during the falling process, The motor group module 104 is controlled by the anti-drop control module 102 and the drop protection module 103 to adjust the position of the gravity block 1051 in the center of gravity adjustment module 105. Keep the mobile terminal in a balanced state.

Specifically, for the self-balancing calibration module 108, its function is to provide self-balancing adjustment for the drop protection module. Understandably, taking a mobile phone as an example, for a state of a horizontally falling mobile phone, such as a free fall from a certain platform or desktop to the ground, if the overall center of gravity of the mobile phone is evenly distributed, there will be no top-heavy state, the mobile phone If the overall center of gravity of the mobile phone is uneven, in the process of free fall, it will cause vertical damage or vertical corners due to imbalance, causing relatively large damage to the mobile phone. Therefore, in this case, it is necessary to adjust the center of gravity of the self-balancing calibration module 108 to be uniform, so that even if an accidental fall occurs, when other anti-drop protection mechanisms are not opened in time, the horizontal landing can be balanced, and the mobile phone can be reduced. degree of damage.

Therefore, the user first needs to self-calibrate the gravity block 1051 in the center of gravity adjustment module 105 through the self-balancing calibration module 108. The self-balancing calibration module 108 adjusts the center of gravity adjustment module of the mobile phone to a central symmetrical position according to different gravity point position detections of the mobile phone, so that the mobile phone can be in a self-balancing state when the mobile phone is free to fall in the horizontal direction. In a specific implementation, after receiving the calibration instruction of the user, the self-balancing calibration module 108 prompts the user to perform one or three short-distance 10-30 CM free-fall calibration, which can be horizontally released from the user's right hand, and the left hand is below the right hand 10- When the 30CM is caught, the state detecting module 101 collects the state during the falling process, and the motor group module 104 is controlled by the anti-drop control module 102 and the drop protection module 103 to adjust the position of the gravity block 1051 in the center of gravity adjustment module 105 so as to be balanced. status. If the self-balancing calibration is successful, the mobile phone will not tilt to the level after each calibration. The LCD display interface on the mobile phone will prompt PASS, the user can use it normally; if the self-balancing calibration fails, the LCD display interface will prompt FAIL. The user needs to recalibrate until it is successful.

The embodiment provides a anti-drop device 10 applied to a mobile terminal, which forms an air protection layer on the ground by controlling the position of the center of gravity of the mobile terminal and generating a compressed airflow, thereby realizing protection and buffering of the landing of the mobile terminal, thereby eliminating the need for additional Increase the impact-resistant parts and protect them during the fall Hold the mobile terminal to balance the landing, and buffer the impact generated when falling, to avoid damage caused by landing at the corners of the mobile terminal when falling.

Based on the same technical concept of the foregoing embodiment, referring to FIG. 5, a method for preventing a fall of a mobile terminal according to an embodiment of the present invention is shown. The method can be applied to a drop prevention device of a mobile terminal, in a specific implementation process. The anti-drop device can be designed as an edge portion of the mobile terminal to become an integral part of the mobile terminal; it can also be designed as an edge casing of the mobile terminal to be coupled with the mobile terminal. The method can include:

S501: Determine, according to the collected sensor data of the mobile terminal, that the mobile terminal is in a falling state;

S502: Generate a posture adjustment instruction and an adjustment parameter according to the falling state value of the mobile terminal and the preset anti-drop strategy;

S503: Adjust a gravity center position and a falling posture when the mobile terminal is dropped according to a preset control strategy, a posture adjustment instruction, and an adjustment parameter.

It can be understood that if the result of the falling of the mobile terminal is that the rear shell is landing and landing horizontally, it is possible to avoid damage or cracking of the mobile terminal due to the corners.

Illustratively, the sensor data of the mobile terminal may include gravity acceleration detected by the acceleration sensor existing by the mobile terminal itself, x-axis, y-axis, z-axis acceleration and angular velocity detected by the three-axis gyroscope, and the light sensor. The amount of light detected. Therefore, step S501 may specifically include:

When the mobile terminal is in a falling state and the three-axis gyroscope detects that the current angular rate change value of the mobile terminal exceeds a preset first threshold value, confirms the tilt value of the mobile terminal in each direction during the falling process; and

When the mobile terminal is in a falling state and the light sensor detected by the light sensor decreases by more than the second At the threshold, confirm that the LCD is facing down during the fall of the mobile terminal.

Illustratively, in combination with the structure of the anti-drop device of the foregoing embodiment, the anti-fall device includes a motor group module and a center of gravity adjustment module. Accordingly, step S503 may specifically include: adjusting an instruction and adjusting parameters according to a preset control strategy and posture. Control the working state of the motor group module and the center of gravity adjustment module, and adjust the position of the center of gravity and the falling posture when the mobile terminal is dropped.

In a preferred implementation, the motor module includes at least two vibration motors; preferably, the vibration motor included in the motor module can be disposed at a corresponding corner position of the mobile terminal.

The center of gravity adjustment module may include a gravity block disposed in the sliding cavity of the edge position corresponding to the mobile terminal, and connected to the vibration motor in the motor group module through a connecting line, as shown by the oblique square in FIG. It can be understood that the sliding cavity is a track for the sliding of the gravity block, and can be disposed on the edge of the corresponding casing of the mobile terminal, and specifically can be a plastic hollow cavity, and the gravity block can move quickly in the hollow cavity. The sliding cavity may be set to at least one of a vertical or horizontal direction of the mobile terminal, or may be set to two groups of vertical and horizontal directions, as shown by the dashed box surrounding the diagonal square in FIG. This embodiment is described by taking four vibration motors and four corresponding gravity blocks shown in FIG. 2 as an example, and is not intended to limit the technical solution. Preferably, the gravity block may be made of a substance having a magnetic property; accordingly, an electromagnetic relay unit made of a semi-magnetic material is disposed around the periphery of the sliding cavity, as shown by the dot-filled square in FIG. When the mobile terminal is in a normal use state, the electromagnetic relay unit is in a power-on state, has magnetic properties, and the gravity center block is attracted by the electromagnetic relay unit, is in a relatively fixed state, and the vibration motor is non-straightened between the rotor and the center of gravity block. Connection relationship; when the mobile terminal is in a falling state, the electromagnetic relay unit is powered off, the electromagnetic relay unit is in a power-off state, and then the magnetism is lost, the attraction force of the gravity block is weakened, and under the pulling of the vibration motor, the connecting line Straightening, and then the gravity block moves in the sliding cavity until the vibration motor stops, the electromagnetic relay unit is energized, and the gravity center block is attracted by the electromagnetic relay unit, and is again in a relatively fixed state.

Further, controlling the working state of the motor group module according to the preset control strategy and the posture adjustment command and the adjustment parameter may specifically include:

Controlling the running direction of the vibration motor in the motor module by the attitude adjustment command and the adjustment parameter, such as forward running and reverse running; and controlling the running amplitude of the vibration motor in the motor module, such as small deflection, large centrifugal movement; and controlling the motor The operating speed of the vibration motor in the group module, such as slow speed, medium speed and high speed; and the running time and step value of the vibration motor in the motor module.

The working state of the center of gravity adjustment module is controlled according to a preset control strategy, a posture adjustment command, and an adjustment parameter, which may specifically include:

Adjusting the running number of one or more sets of vibration motors in the motor group module, adjusting the sliding direction of the gravity block of the center of gravity adjustment module, thereby adjusting the center of gravity of the mobile terminal to the balance direction. The above-described adjustment sliding direction may include lateral movement, or longitudinal movement, or flexible movement in four directions of up, down, left, and right.

It can be understood that the anti-drop device can complete the above control by controlling the software code command of the motor group module to complete the specific custom parameter modulation by changing different motor drive commands and parameters. At the same time, the torque generated by each parameter adjustment and the parameter mode of the running direction are pre-established. In the specific implementation process, the anti-drop device compares the drop state value of the currently detected mobile terminal with the preset target balance state model, and calculates a corresponding posture adjustment command and an adjustment parameter; and adopts the attitude adjustment command and the adjustment parameter. The corresponding adjustment control is performed until the anti-drop device detects that the mobile terminal is safely landing according to the target equilibrium state model.

In combination with the specific structure and working principle of the motor module and the center of gravity adjustment module, the step S502 may specifically include:

When it is determined that the current drop state of the mobile terminal is a slight imbalance according to the drop state value of the mobile terminal, an instruction and a motion parameter for indicating the eccentric motion of the vibration motor in the motor group module are generated to make the eccentricity of the vibration motor in the motor group module Torque to achieve mobile phone imbalance Tune. Specifically, when the vibration motor is in operation, the eccentric wheel on the rotating shaft of the vibration motor also rotates together, and since the center point of the eccentric wheel is not at the center of the vibration motor, the vibration motor is in a state of constant loss of balance. Vibration, thereby vibrating the motor for eccentric motion.

When determining that the current drop state of the mobile terminal is the imbalance of the center of gravity of the mobile terminal according to the drop state value of the mobile terminal, generating an instruction and a parameter for instructing the vibration motor in the motor group module to control the movement of the gravity block in the gravity center adjustment module, The center of gravity of the mobile terminal is restored to the target equilibrium state by causing the gravity block in the gravity center adjustment module connected thereto by the vibration motor to rotate. Specifically, the command and parameters for indicating the vibration motor in the motor group module to control the movement of the gravity block in the center of gravity adjustment module may include the rotational speed, the amplitude, the number of revolutions, the step value, and the like of the vibration motor in the motor group module.

It should be noted that, in order to be able to assist in adjusting the position of the center of gravity and the falling posture when the mobile terminal is dropped, and to buffer during landing, as shown in FIG. 3, the anti-drop device may further include: a vibration motor for placing the motor module. The aperture sealing cavity is as shown by the dotted line frame in FIG. 3; accordingly, the method may further include:

Controlling the falling posture of the mobile terminal when it is dropped by the recoil force of the compressed airflow generated by the high-speed rotation of the vibration motor in the motor module; and, when the mobile terminal is close to the ground, the compressed airflow generated by the high-speed rotation of the vibration motor in the motor module The ground forms an air protective layer to buffer the landing of the mobile terminal.

It can be understood that the vibration motor in the motor unit module can be rotated at a high speed by the attitude adjustment command and the adjustment parameter generated by the anti-drop device, thereby generating a compressed air flow in the open-hole sealing cavity. Moreover, controlling the falling posture of the mobile terminal when it is dropped by the recoil force of the compressed airflow is generally only applicable to the adjustment of the slight unbalanced state of the mobile terminal.

In addition, in order to prevent the false triggering of the anti-drop device from working, the method may further include: collecting an operating state of the mobile terminal; and turning off the function of the anti-drop device when the working state of the mobile terminal satisfies a preset ignore condition.

Moreover, the method may further include: acquiring a balanced landing state of the mobile terminal; specifically, the method may include:

According to the position of the center of gravity of the different mobile terminals, the center of gravity adjustment module is adjusted to the central symmetrical position, so that the mobile terminal can be in a self-balancing state when it is free to fall in the horizontal direction.

In the preferred implementation process, after receiving the calibration command issued by the user, the anti-drop device prompts the user to make a free landing and short-distance falling body, and according to the foregoing scheme, according to the state in the falling process, the motor group module is controlled to adjust the center of gravity. Adjust the position of the gravity block in the module to make the mobile terminal in a balanced landing state.

The embodiment provides a method for preventing a fall of a mobile terminal. The air protection layer is formed on the ground by controlling the position of the center of gravity of the mobile terminal and generating a compressed airflow, thereby realizing protection and buffering of the landing of the mobile terminal, thereby eliminating the need for additional The anti-impact component keeps the mobile terminal balanced and landing during the falling process, and buffers the impact generated during the fall to avoid the damage caused by landing at the corner of the mobile terminal when falling.
