Four-rotor unmanned aerial vehicle capable of dwelling and stopping on vertical plane

Abstract

The invention discloses a four-rotor unmanned aerial vehicle capable of dwelling and stopping on a vertical plane, and belongs to the field of four-rotor unmanned aerial vehicles. The four-rotor unmanned aerial vehicle comprises a four-rotor unmanned aerial vehicle body and a vertical plane dwelling device, and the vertical plane dwelling device is fixedly installed below a fuselage of the four-rotor unmanned aerial vehicle body; the four-rotor unmanned aerial vehicle adopts an X layout, four motors are arranged at four end parts of vehicle arms, and the motors are connected with electronic speed regulators and are used for carrying out thrust control; the vertical plane dwelling device comprises cantilever claws, extension springs, a relaxation pull wire and a steering engine assembly; the cantilever claws are hinged to the front and rear parts of the unmanned aerial vehicle body, and the acting forces of the cantilever claws on the wall surface are increased through resilience forces of extension springs arranged in the middle; the steering engine assembly is installed in the middle of the lower portion of the unmanned aerial vehicle body and used for controlling and loosening the pull wire, then the cantilever claws of the front side dwelling device and the rear side dwelling device are pulled open in the spanwise direction, and acting force of the cantilever claws on the wall face is eliminated. The four-rotor unmanned aerial vehicle can be switched between the air mode and the dwelling mode, the task time of the unmanned aerial vehicle can be effectively prolonged, and the cooperative gain of the unmanned aerial vehicle and the dwelling device is improved.
