Abstract
The invention discloses a water-air amphibious unmanned vehicle which comprises a flight assembly, a navigation assembly and a cabin assembly. The flying assembly comprises two annular supports which are oppositely arranged, supporting rod units are arranged on the two annular supports, first motors are arranged on the supporting rod units, ball screws are arranged on output shafts of the first motors, the ball screws are sleeved with folding support units, and a plurality of propellers are arranged at the ends, away from the first motors, of the folding support units. The navigation assembly comprises two power mechanisms and two gear shifting mechanisms which are oppositely arranged, each power mechanism comprises two gear disc units and a plurality of paddles, each gear disc unit comprises an inner gear ring, a connecting ring and an outer gear ring, and each gear shifting mechanism comprises a fixing support connected with a supporting rod unit and an annular support which are integrally shared. The high-speed maneuvering advantage of air flight is reserved, the water surface navigation operation capacity is enhanced, and the amphibious requirement of an actual combat scene is better met.
