Device for arm folding and turning of multi-rotorcraft

Abstract

The invention discloses a device for arm folding and turning of a rotorcraft and belongs to the field of structural design of an unmanned rotorcraft. The device is composed of a telescopic assembly, amotor plate assembly, a locking assembly, a main control assembly and a rotating assembly, wherein the motor plate assembly is connected with an upper portion of an outer side of the telescopic assembly, an inner side of the telescopic assembly and an outer side of the locking assembly are parallel and connected together, the locking assembly is fixed above the rotating assembly, the main controlassembly is fixed above a rotorcraft bottom plate, a base of the rotating assembly is fixed above the rotorcraft bottom plate, and the main control assembly and the rotating assembly are parallel onthe rotorcraft bottom plate. The device is advantaged in that the length of vehicle arms is reduced and extended through stretching, transportation and carrying are facilitated in a reduced state, problems that the rotorcraft is large in unfolding area and inconvenient to transport and carry are solved, accelerating and decelerating effects are achieved through rotation of the vehicle arms, and problems of accelerating and decelerating in a short time and saving the electric quantity are solved.

Description

Technical field [0001] The invention relates to a device for folding the arms of a multi-rotor unmanned aerial vehicle and changing the flight mode. Specifically, it reduces the space occupied by the rotorcraft by changing the arms, and changes the flight mode by changing the angle of the arms. The field of structural design of human rotorcraft. Background technique [0002] With the improvement of people’s quality of life and the development of science and technology, the field of unmanned aerial vehicles represented by multi-rotor aircraft is developing rapidly. The application fields also involve aerial photography, electric cruise, pesticide spraying and other fields, because of the fixed shape mechanism of multi-rotor aircraft. , It occupies a particularly large area and is not suitable for fast and convenient transportation, which reduces work efficiency. The extended arm also reduces the reliability of use due to the bumps in transportation. The fixed arm is not conducive ...
