Abstract

The invention discloses an airphibious four-rotor aircraft. The airphibious four-rotor aircraft comprises four execution mechanisms and a driving deformation mechanism. The driving deformation mechanism comprises a driving motor, two driving shafts and two driven shafts. The driving shafts and the driven shafts are arranged on supporting seats, and the driving motor is provided with two motor output shafts; each motor output shaft is connected with the corresponding driving shaft through a coupler, and each driving shaft is connected with the corresponding driven shaft through a gear pair; and rotor supports of two execution mechanisms are connected with the two driving shafts respectively, and rotor supports of the other two execution mechanisms are connected with the two driven shafts respectively. Air-land double purposes of the four-rotor aircraft can be conveniently and rapidly achieved, and when the road is flat, the airphibious four-rotor aircraft can serve as a robot trolley to walk; when obstacles occur, the robot trolley can be transformed to the four-rotor aircraft to fly over the obstacles; and the two manners are switched for walking, energy consumption can be saved, and the cruising power of the aircraft can be improved.

Description

technical field [0001] The patent of the present invention relates to a quadrotor aircraft, specifically a quadrotor aircraft capable of using the rotors of the quadrotor aircraft as wheels for both air and ground purposes. Background technique [0002] In 1907, Bréguet Richet took the world's first quadrotor aircraft "Gyroplane No. 1" into the sky. Quadrotor aircraft is a relatively common and classic small aircraft, which is widely used in military reconnaissance, resource survey, civil aerial photography and other technical fields. The aircraft is compact in structure and flexible in movement, and is suitable for use in narrow spaces or complex environments. [0003] In the 1980s, the United States developed a small aircraft that used ducted fans to provide lift for small aircraft for aerial reconnaissance and surveillance, laying the foundation for the use of ducted fans on aircraft. [0004] And with the good flight performance of the quadrotor aircraft, the land oper...
