Problems solved by technology

[0002] Nowadays, the use scenarios of mobile terminals are becoming more and more complex, and the industry and users have higher and higher requirements for the anti-drop performance of terminals. As the screens of terminals are getting larger and thinner, the borders are getting smaller and even smaller. There is no border, which leads to weaker and weaker anti-drop performance of the terminal
Therefore, the quality of anti-drop performance is a very important indicator of high-performance terminals, which affects the stability and service life of the whole machine

example 1

[0109] As shown in Figure 7(A), the charge sensing element includes the antennas at the four corners of the terminal. When the terminals are all placed on the table, since all the projected areas of the antennas at the four corners of the terminal are on the table, the charge collection circuit will test out a If the induced charge value is relatively large, and the induced charge value is the same as the induced charge value corresponding to the pre-stored desktop material property, it can be determined that the terminal is safely placed on the desktop.

[0110] As shown in Figure 7(B), if the induced charge value detected by a certain charge sensing element at the bottom of the terminal is very small, such as 1fF, the system will automatically adjust the amplification gain to detect its distance to the ground. If the distance to the ground is greater than A preset threshold, such as 0.5 meters, can determine that the bottom of the current terminal is placed in the air.

example 2

[0112] As shown in Figure 8(A), when the terminal is placed on the human hand, the induced charge values ​​of the three areas A, B, and C are obtained, and it is judged that the terminal is in contact with the human hand in the three areas A, B, and C, and it can be identified that the terminal is in In the normal hand grip range, the detection terminal is placed on the user's hand, and it is judged that the terminal is in a stable and safe state at three points.

[0113] If the terminal moves on the human hand and becomes the position shown in Figure 8(B), at this time, it is detected that the induced charge value in area A is the same as the induced charge value corresponding to the pre-stored air medium, not the human hand, while areas B and C are still On the human hand, it is judged that the upper left side of the terminal is out of the range of the hand grip and does not belong to the three-point stable state, and an alarm can be sent at this time.

example 3

[0115] Such as Figure 9 As shown, in this embodiment, when it is determined that the terminal is in a free fall state, the distance between the terminal and the ground is detected, and when the changes in the induced charge values ​​detected by the charge sensing elements located at the four corners of the terminal are relatively equal values, it is determined that the terminal Land horizontally.

Abstract

A protection device and method, the protection device comprising: one or more charge sensing elements arranged on a terminal, a charge collection circuit connected to the charge sensing elements, and a state detection module connected to the charge collection circuit, the The charge collection circuit generates charges and radiates them through the charge sensing elements, collects the charges reflected from each of the charge sensing elements to generate corresponding induced charge values, and outputs the induced charge values ​​of each charge sensing element to the state detection module; the state detection module is configured to judge whether the terminal is in a falling state according to the induced charge value. The solution provided by this application can determine whether the terminal has fallen.

Description

technical field [0001] The present invention relates to terminal technology, in particular to a protection method and device. Background technique [0002] Nowadays, the use scenarios of mobile terminals are becoming more and more complex, and the industry and users have higher and higher requirements for the anti-drop performance of terminals. As the screens of terminals are getting larger and thinner, the borders are getting smaller and even smaller. Without borders, the terminal's anti-drop performance is getting weaker and weaker. Therefore, the quality of anti-drop performance is a very important indicator of high-performance terminals, which affects the stability and service life of the whole machine. Contents of the invention [0003] At least one embodiment of the present invention provides a protection method and device for timely judging whether a terminal is dropped. [0004] In order to achieve the purpose of the present invention, at least one embodiment of ...
