an inflatable component 1 is arranged in the accommodating space;
one end of the inflation component 1 is connected with the accommodating space, and the end far away from the accommodating space is connected with the bottom shell cover 4;
the elastic component 2 is positioned in the accommodating space, one end of the elastic component is abutted against the bottom shell surface cover 4, the end far away from the bottom shell surface cover 4 is fixed on the bottom shell 3, and the elastic component 2 is in a compressed state;
when the sensor detects abnormality, the control circuit board 5 controls the movable locking device 7 to move, so that the bottom shell cover 4 is separated from the bottom shell 3, the elastic component 2 extends towards the direction away from the bottom shell 3 to pop the bottom shell cover 4 outwards, and the inflation component 1 expands after contacting with external air.
In the embodiment of the present invention, the inflatable member 1 is an airbag, the elastic member 2 is a spring, and the accommodating space is the first groove 6. The sensor, the control circuit board 5 and the movable locking device 7 are respectively electrically connected with a power supply 17, and the power supply 17 supplies voltage to the sensor, the control circuit board 5 and the movable locking device 7. When the bottom cover 4 is separated from the bottom case 3, the air charging member 1 is connected to the bottom cover 4 so that the bottom cover 4 is not separated from the bottom case 3, so that the bottom cover 4 is lost. The spring is located first recess 6, and the spring does not contact with the gasbag for when the gasbag was in the compression state, the shrivelled state promptly, avoid the gasbag to hinder the spring and pop out towards keeping away from drain pan 3 direction. The spring is used for driving the bottom shell surface cover 4 to be separated from the bottom shell 3, so that the air bag positioned in the first groove 6 can be fully contacted with the external air. When the sensor detects unusual, if detect that the protective sheath descends or the protective sheath soaks with higher speed, control circuit board 5 control activity locking device 7 moves for bottom shell face lid 4 breaks away from bottom shell 3, and the spring extends towards keeping away from bottom shell 3 direction, and the gasbag expands behind the contact outside air. Increase the whole volume of protective sheath, reduce the whole density of protective sheath and mobile device 8 to increase the buoyancy that mobile device 8 received, slow down or stop mobile device 8 and sink. With the above arrangement, waterproof sinking of the mobile device 8 is achieved without changing the design of the mobile device 8. In other embodiments of the present invention, the first groove 6 is quadrilateral, each edge of the first groove 6 is provided with one inflation component 1, one end of each inflation component 1 is connected with the edge of the first groove 6, and the end far away from the edge of the first groove 6 is connected with the bottom shell cover 4. Therefore, when the bottom shell surface cover 4 is separated from the bottom shell 3, the four inflation components 1 respectively positioned on the four sides of the first groove 6 expand simultaneously after contacting with the external air, so that the problem that the protective sleeve cannot realize the function of preventing the mobile device 8 from sinking due to the damage of the single inflation component 1 is avoided.
