The acceleration sensor 20 can be a two-axis acceleration sensor (Two-Axis Accelerator), a three-axis acceleration sensor (Three-Axis Accelerator) and the like. The electronic gyroscope 21 can be a two-axis gyroscope (Two-Axis Gyro), a three-axis gyroscope (Three-Axis Gyro) and the like.

Referring to FIG. 4A , the anti-collision protection device 22 includes an actuating unit 220 , a movable bracket 221 , a fixed frame 222 , a tenon 223 , a spring 224 and an anti-collision material 225 . The actuating unit 220 is connected to the body 26 of the handheld device 2, the first end of the movable bracket 221 is connected to the actuating unit 220, the second end is connected to the tenon 223, and the fixed frame 222 is placed in the tenon 223 close to the side of the movable bracket 221. On one side, the anti-collision material 225 is connected with the spring 224 and is locked by the tenon 223 .

The body 26 of the handheld device 2 refers to the shell of the handheld device 2 , including the front (ie screen), side and back. The anti-collision material 225 can be rubber or metal. A schematic diagram of the exploded structure of the anti-collision protection device 22 is shown in FIG. 4B .

When the anti-collision protection device 22 is not activated, the spring 224 is in a compressed state, and the anti-collision material 225 connected to the spring 224 is fixed inside the tenon due to the limitation of the tenon 223 .

5, the anti-collision protection device 22 is arranged at four corners of the body 26 of the handheld device 2, and each corner is provided with two such anti-collision protection devices 22, one on the upper layer and one on the lower layer. In this embodiment, the number of the anti-collision protection devices 22 is 8, 4 on the front and 4 on the back. Of course, the number of installations and the location of the setting points of the anti-collision protection devices 22 can also be adjusted according to the shape characteristics of different handheld devices 2 .

When the screen impact prevention system 24 detects that the handheld device 2 is in a falling state, the screen impact prevention system 24 will immediately push the movable bracket 221 forward through the actuating unit 220. Moving forward, the tenon 223 is loosened due to being hindered by the fixed frame 222. At this time, the anti-collision material 225 connected to the spring 224 in the tenon 223 is limited by the anti-collision material 225, which is immediately released and bounced upward. The opening 260 of the body pops out to become a shock buffer protection device for the handheld device 2 .

In this embodiment, the screen impact prevention system 24 can be divided into one or more modules, and the one or more modules are stored in the memory 23 and configured to be controlled by one or more processors ( In this embodiment, one processor 25) is executed to complete the present invention. For example, referring to FIG. 2 , the screen impact prevention system 24 is divided into a state data acquisition module 240 , a movement state determination module 241 and an instruction sending module 242 . The module referred to in the present invention is a program segment that completes a specific function, and is more suitable for describing the execution process of software in the processor 25 than a program. The functions of each module will be described in detail in the flow chart of FIG. 3 .

As shown in FIG. 3 , it is a flow chart of protecting the screen of the handheld device by using the built-in anti-collision protection device of the handheld device.

Step S10 , the state data acquiring module 240 acquires the acceleration of the handheld device 2 detected by the built-in acceleration sensor 20 of the handheld device 2 and the flip angle of the handheld device 2 detected by the electronic gyroscope 21 .

Step S11 , the moving state determining module 241 determines the moving state of the handheld device 2 according to the acceleration and the turning angle of the handheld device 2 . In this embodiment, the moving state includes a falling state and a safe state.

For example, if the acceleration of the handheld device 2 is greater than a first preset value, and the flip angle of the handheld device 2 is greater than a second preset value, the moving state determining module 241 determines that the handheld device 2 is in a falling state. In this embodiment, the first preset value is 6.5(g), and the second preset value is 60 degrees.

If the acceleration of the handheld device 2 is less than or equal to the first preset value, or the flip angle of the handheld device 2 is smaller than or equal to the second preset value, the moving state determination module 241 determines that the handheld device 2 is in a safe state.

It should be pointed out that the mobile state detection method used in the present invention is not limited to the above example method, and those skilled in the art can also use other mobile state detection technologies with the same function. For example, in other embodiments, only the acceleration of the handheld device 2 may be used to determine whether the handheld device 2 is in a falling state. If the acceleration of the handheld device 2 is greater than the first preset value, the moving state determination module 241 judges that the handheld device 2 is in a falling state.

In other embodiments, the acceleration sensor 20 can also be used to detect the movement amount of the handheld device 2 in the Z-axis of the three-dimensional space coordinate system per unit time. When the movement amount is greater than the third preset value, the movement state determination module 241 It is judged that the handheld device 2 is in a falling state.

In step S12, the moving state determining module 241 judges whether the handheld device 2 is in a falling state. If the handheld device 2 is in a falling state, then step S13 is performed. If the handheld device 2 is not in the falling state, then return to step S10.

In step S13, the command sending module 242 sends a drive command to the actuating unit 220 of the anti-collision protection device 22, and the movable bracket 221 of the anti-collision protection device 22 at each position of the handheld device body 26 is pushed forward by the actuation unit 220.

Step S14, the tenon 223 of the anti-collision protection device 22 is temporarily loosened due to being pushed to the fixing frame 222 (see FIG. 6A).

Step S15, the anti-collision material 225 of the anti-collision protection device 22 pops out of the openings of the body 26 of the handheld device 2 when the tenon 223 is released (refer to FIG. 6B ), so as to protect the body 26 of the handheld device 2 .

In step S16, the user can manually press the ejected anti-collision material 225 back into the body of the handheld device 2 until it pops up again when the anti-collision protection device 22 is activated next time.

Referring to FIG. 7 , after the movable bracket 221 of the anti-collision protection device 22 is pushed forward by the actuating unit 220, it returns to the original position again, and the tenon 223 of the anti-collision protection device 22 is no longer pushed by the fixed frame 222. , and immediately bounce back to the original place. When the user picks up the handheld device 2 again and presses the ejected anti-collision material 225 back into the body of the handheld device 2, the anti-collision material 225 will be restricted by the tenon 223 again and will no longer pop up.

It should be pointed out that the anti-collision material 225 of the present invention can also protect the handheld device 2 in other different forms. For example, in other embodiments, the anti-collision material 225 can be made into a shape as shown in FIG. 8 .

Referring to FIG. 8, after the anti-collision material 225 pops out of the opening 260 of the body, one or more telescopic parts 300 (two are shown in the example in FIG. 8 ) will pop out from the inside of the anti-collision material 225, so as to increase the durability of the handheld device 2. The protection point improves the protection effect of the anti-collision protection device 22 on the handheld device 2 . When the user needs to press the anti-collision material 225 back into the body of the handheld device 2 , the telescopic member 300 is first pressed back into the anti-collision material 225 , and then the anti-collision material 225 is pressed back into the body of the handheld device 2 .

Of course, from the perspective of reducing the manufacturing cost of the handheld device 2, the anti-collision protection device 22 may also be provided only on the front of the handheld device 2 (ie, the side where the screen is located) to provide protection against the impact of the screen.

In summary, the present invention detects in real time whether the handheld device 2 is in a falling state, and when it is detected that the handheld device 2 is in a falling state, automatically activates the built-in anti-collision protection device 22 of the handheld device 2 to effectively reduce the impact of the handheld device 2. The impact force when falling to the ground can avoid damage to the handheld device 2 .
