Amphibious unmanned plane

The invention discloses an amphibious unmanned plane, and the unmanned plane comprises a plane body. The interior of the plane body is provided with a processing unit and an engine, which are electrically connected with each other. The bottom of the plane body is provided with an undercarriage, and the undercarriage comprises an air bag and an undercarriage body. The air bag covers the surface of the undercarriage body. The interior of the plane body is also provided with an air filling device, and the air filling device is in transmission connection with the engine and is electrically connected with the processing unit. An air outlet of the air filling device is communicated with the air bag. The interior of the machine body is also provided with an acceleration inductor, and the acceleration inductor is electrically connected with the processing unit. The unmanned plane employs the principle of a swim ring to achieve an amphibious function, thereby preventing the electronic equipment from being damaged after the drone falls into water.
