the drop detection sensor 120 obtains a drop height when the electronic device is in a free-fall state;
the processor 110 determines a control parameter of a reverse motion according to the falling height, wherein the motion direction of the reverse motion is opposite to the vector direction of the first speed parameter of the electronic equipment;

Referring to fig. 1B, an electronic device described with reference to fig. 1A is a schematic flow chart of an embodiment of a fall protection method according to an embodiment of the present disclosure. The fall protection method is applied to electronic equipment, the electronic equipment comprises a processor, and a fall detection sensor and a driving device which are connected with the processor, and the fall protection method can comprise the following steps:
101. and when the electronic equipment is in a free falling body state, acquiring the falling height.
When the electronic equipment is in a free-falling body state, the electronic equipment is indicated to fall in an unconscious state, and the electronic equipment is easy to damage. In the embodiment of the application, the electronic equipment can acquire the falling height through the falling detection sensor. Different falling heights and gravity do different work on the electronic equipment, so that the stress between the electronic equipment and the ground is different, and the electronic equipment is more likely to be damaged if the stress is larger.
102. And determining a control parameter of reverse motion according to the falling height, wherein the motion direction of the reverse motion is opposite to the vector direction of the first speed parameter of the electronic equipment.
The first speed parameter in the embodiment of the present application may be one of the following: acceleration, velocity, angular velocity, and the like. Since the first speed parameter is a vector, it corresponds to a vector direction. The control parameter may be at least one of: the control time is duration of reverse motion, the control speed is speed of the reverse motion, the speed and the direction are variable, the control force is acting force of a control driving device, the control power is power of the control driving device, the control current is working current of the control driving device, the control voltage is control voltage of the control driving device, and the control energy is required to do work for controlling the reverse motion.
In addition, the landing time of the electronic equipment is different at different falling heights, so that the control parameter of the reverse motion of the electronic equipment can be determined according to the falling heights, and the motion direction of the reverse motion is opposite to the vector direction of the first speed parameter of the electronic equipment. For example, the second velocity parameter vector of the reverse motion may be reversed opposite to the gravitational acceleration direction. As shown in fig. 1C, it can be seen that the first speed parameter is opposite to the reverse motion direction, and thus, the reverse motion can slow down the fall tendency.
Optionally, the second speed parameter of the reverse motion is less than or equal to the first speed parameter. Thus, the falling tendency of the electronic equipment can be relieved.
Optionally, the second speed parameter of the reverse movement is greater than the first speed parameter, so that the electronic device can be turned over in the air, and the falling angle of the electronic device can be adjusted. For example, originally the screen was dropped downwards, and after the reverse motion adjusted the drop of the electronic device, the electronic device can now be dropped with the back cover downwards.
Of course, the magnitude of the second speed parameter of the reverse motion may be determined according to practical situations, and is not limited herein.
Optionally, between the step 101 and the step 102, the following steps may be further included:
a1, predicting the stress between the electronic equipment and the ground;
a2, acquiring a falling angle of the electronic equipment, and determining a hardware part of the electronic equipment, which is firstly contacted with the ground, according to the falling angle;
a3, determining a stress threshold corresponding to the hardware part;
a4, when the force is larger than the force threshold, executing the step of determining the control parameter of the reverse movement according to the falling height.
The electronic equipment is arranged on different grounds and suffers from different buffer forces from the ground, so that the stress between the electronic equipment and the ground can be estimated by combining different ground materials and the falling speed. The falling angle of the electronic equipment can be detected by the falling detection sensor, different falling angles determine that the hardware part of the electronic equipment firstly contacting the ground is different, specifically, the mapping relation between the falling angle and the hardware part firstly contacting the ground can be preset, and the mapping relation can be obtained through a large number of experiments. Of course, the stress thresholds of different hardware parts are different, for example, the stress thresholds of the screen falling and the rear cover falling are different, it can be understood that if the stress threshold is exceeded, the electronic device is damaged, and if the stress threshold is smaller than the stress threshold, the electronic device is relatively safe, the mapping relation between the hardware part and the stress threshold can be stored in the memory of the electronic device in advance, and then according to the mapping relation, the stress threshold corresponding to the hardware part firstly contacting the ground can be obtained, when the stress is larger than the stress threshold, the electronic device is very likely to be damaged, and at this time, the falling data of the electronic device can be obtained.
Optionally, in the step a1, estimating the stress between the electronic device and the ground may include the following steps:
a11, acquiring the ground material and the current falling speed;
a12, determining buffer duration corresponding to the ground material;
a13, determining the final falling speed of the electronic equipment when falling to the ground according to the current falling speed and the falling height;
and A14, determining the stress between the electronic equipment and the ground according to the final falling speed, the buffering time and the momentum theorem.
The different buffering time lengths corresponding to different ground materials are different, the mapping relation between the ground materials and the buffering time lengths can be preset, then the ground materials can be detected by the aid of the camera, and the buffering time lengths corresponding to the ground materials are determined according to the mapping relation. Certainly, knowing the current falling speed and the current falling height, the final falling speed of the electronic device when falling to the ground can be obtained by a free fall formula, and then the stress between the electronic device and the electronic device can be obtained according to the momentum theorem, which is specifically as follows:
mv＝ft
wherein m is the mass of the electronic device, m is a known quantity (the mass of the electronic device), v is the final falling speed, t is the buffering duration, and f is the stress between the electronic device and the ground.
Optionally, the hardware portion may be one of: a screen, a back cover, a housing, a camera, etc., which are not particularly limited herein.
Further optionally, in step 102, the determining the control parameter of the reverse movement according to the falling height may include the following parameters:
21. determining a target falling speed corresponding to the stress threshold;
22. determining the minimum energy required to be generated by the reverse motion according to the final falling speed, the target falling speed and a kinetic energy conservation law;
23. configuring control parameters of the reverse motion according to the minimum energy.
The falling speed is different when the electronic equipment falls to the ground, and the stress between the electronic equipment and the ground is different, so that the corresponding relation between the stress threshold and the falling speed can be stored in the electronic equipment in advance, and the target falling speed corresponding to the stress threshold can be determined according to the corresponding relation.
Furthermore, the minimum energy required to be generated by the reverse motion can be calculated according to the following formula:
wherein E isminRepresenting minimum energy, m representing mass of the electronic device, v2Indicates the final drop velocity, v1Representing the target fall velocity. Of course, the amount of work required to be done by the reverse motion is not less than the minimum energy, and the minimum energy required to be produced by the reverse motion can be completed before the electronic device falls to the ground. And the minimum energy can be configured to the speed of the reverse motion,Duration, acceleration, power, current, voltage, etc. The corresponding relationship between the minimum energy and the control parameter can be preset, and then the control parameter can be rapidly configured according to the corresponding relationship.
103. And controlling the electronic equipment to perform the reverse motion according to the control parameter.
The electronic equipment can be controlled to move reversely according to the control parameters, so that the falling trend is reduced, the electronic equipment can safely fall to the ground, and the damage degree of the electronic equipment is reduced.
It can be seen that the fall protection method described in the embodiment of the present application is applied to an electronic device, where the electronic device includes a processor, and a fall detection sensor and a driving device connected to the processor, and is capable of acquiring a fall height when the electronic device is in a free fall state, determining a control parameter of a reverse motion according to the fall height, where a motion direction of the reverse motion is opposite to a vector direction of a first speed parameter of the electronic device, and controlling the electronic device to perform the reverse motion according to the control parameter, so that when the electronic device falls, a motion opposite to the speed parameter direction of the electronic device can be generated to slow down a fall degree of the electronic device, thereby implementing fall protection on the electronic device.
In accordance with the above, please refer to fig. 2, which is a flowchart illustrating an embodiment of a fall protection method according to an embodiment of the present application. The fall protection method described in this embodiment may include the steps of:
201. and when the electronic equipment is in a free falling body state, acquiring the falling height.
202. And when the falling height is greater than a height threshold value, determining a control parameter of reverse motion according to the falling height, wherein the motion direction of the reverse motion is opposite to the vector direction of the first speed parameter of the electronic equipment.
Wherein, in this application embodiment, fall and detect the sensor and can include range finding sensor, fall the height through this range finding sensor detection, perhaps fall and detect the sensor and include two cameras, utilize this two cameras to detect and fall the height. Taking the screen as an example, when the falling height is greater than the height threshold, it indicates that the falling height may cause great damage to the screen of the electronic device, and therefore, step 202 may be performed to perform falling protection on the screen of the electronic device. When the falling height is smaller than or equal to the height threshold, the height is safe, and the electronic equipment is generally not damaged when falling. The height threshold may be set by the user or by default.
Optionally, between the step 201 and the step 202, the following steps may be further included:
