Anti-falling mobile phone shell with active defense function

The invention discloses an anti-falling mobile phone shell with an active defense function, and relates to the technical field of mobile phone accessories, the anti-falling mobile phone shell is provided with an infrared sensor, an acceleration sensor and a gyroscope sensor, the falling state of a mobile phone can be comprehensively judged by capturing changes of data of the three sensors, and the anti-falling mobile phone shell is more accurate and reasonable; the X-shaped support is designed, when the X-shaped support is opened by the elastic buffer piece, the elastic buffer piece provides better buffer performance, and a mobile phone can be better wrapped; the elastic buffer part is selected as an active defense energy storage part, so that when the protection function is executed, each mechanical component reacts quickly, and the mobile phone can be better protected; and after the telescopic shaft of the electromagnetic cylinder is contracted, the two rectangular frames are pressed and overlapped together
