Buffer protection adjustable swing arm position device for single-rotor UAV (unmanned aerial vehicle) servo control system

Abstract

The invention discloses a buffer protection adjustable swing arm position device for a single-rotor UAV (unmanned aerial vehicle) servo control system. The buffer protection adjustable swing arm position device for the single-rotor UAV servo control system is characterized in that the device comprises an active swing arm, a buffer connecting rod and an executive swing arm; the active swing arm isconnected with an output shaft of a servo control actuator of a servo control system, and the active swing arm is driven to rotate by the output shaft; the executive swing arm is fixed on a frame of asingle-rotor UAV through a hinge, and the executive swing arm can rotate round the hinge; the buffer connecting rod is connected between the active swing arm and the executive swing arm and used fortransferring the rotation of the active swing arm to the executive swing arm; the buffer connecting rod is used for absorbing impact energy by self deformation or destruction when the single-rotor UAVis subjected to an impact that can damage a servo control actuator. The buffer protection adjustable swing arm position device for the single-rotor UAV servo control system has the advantage of effectively solving the problem that the servo control system that controls rotor pitch is vulnerable to impact damage when a single-rotor unmanned helicopter falls.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a buffer protection adjustable swing arm position device of a single-rotor unmanned aerial vehicle servo control system. Background technique [0002] At present, single-rotor unmanned helicopters generally adopt a method of controlling the pitch of the main rotor through a servo control system to control the attitude of the aircraft. The internal structure of the servo control system is complex and precise, and the cost is expensive. Most of them are equipped with control boards, brushless motors, reduction gears, output shafts, miniature bearings, magnetic encoder disks and other components. During normal operation, the control board receives the angular position signal from the external controller in real time, controls the rotation of the brushless motor, drives the output shaft to rotate through a series of reduction gears to output angular displ...
