An unmanned aerial vehicle capable of moving on an inclined plane

Abstract

The invention discloses an unmanned aerial vehicle capable of moving on a slope. The unmanned aerial vehicle comprises an aircraft body and crawler-type landing gears, wherein the aircraft body is arranged on the two crawler-type landing gears through two landing supporting rods; the tops of the landing supporting rods are fixedly connected to the aircraft body, and the lower parts of the landingsupporting rods are connected to the crawler-type landing gears through a revolute pair; a hydraulic ejector rod hinged to the aircraft body is arranged on the crawler-type landing gear; a limiting device capable of locking the extending stroke of the hydraulic ejector rod is arranged on the hydraulic ejector rod; and each crawler-type landing gear comprises a trapezoidal supporting plate, load wheels arranged at four vertexes of the trapezoidal supporting plate, and a rubber crawler belt for connecting the plurality of load wheels. The unmanned aerial vehicle can adapt to site inclination through the crawler-type landing gears, so that take-off, landing and advance of the unmanned aerial vehicle on the slope with the determined angle can be realized, a visible light camera and the ultrasonic sensor which carry on the unmanned aerial vehicle can assist in landing, and the take-off and landing efficiency of the aircraft can be improved.

Description

technical field [0001] The invention belongs to the field of aircraft, and relates to an unmanned aerial vehicle, in particular to an unmanned aerial vehicle capable of moving on an inclined plane. Background technique [0002] In recent years, with the development of advanced manufacturing technology and the improvement of flight control system integration, the unmanned aerial vehicle market has developed strongly. As a production tool, unmanned aerial vehicles have been endowed with more practical functions and entered all walks of life and have also achieved good development in the civilian field. Among them, multi-rotor vertical take-off and landing unmanned aerial vehicles have been widely accepted for their simple and excellent control performance. attention and research. [0003] The multi-rotor vertical take-off and landing unmanned aerial vehicle has always had strict requirements on the terrain when it takes off and lands. In order to ensure the stability of the ...
