Three-axis stable pan/tilt of unmanned aerial vehicle

Abstract

The invention relates to the technical field of unmanned aerial vehicles. The invention aims to provide a three-axis stable pan / tilt of an unmanned aerial vehicle. The three-axis stable pan / tilt comprises a connecting mechanism used for being connected with an unmanned aerial vehicle body and a three-axis follow-up mechanism installed on the connecting mechanism. The three-axis follow-up mechanism comprises three steering engines and three L-shaped brackets, the steering engines are respectively a first steering engine, a second steering engine and a third steering engine, and the brackets are respectively a first bracket, a second bracket and a third bracket; the first steering engine is vertically arranged on the connecting mechanism, and the output end of the first steering engine faces downwards and is connected with one end of the first support. The three-axis stable pan / tilt further comprises a control system, and the first steering engine, the second steering engine and the third steering engine are all electrically connected with the control system. The cradle head is prevented from inclining along with the unmanned aerial vehicle, the advantages of being low in cost and sensitive in reaction are achieved, and an existing unmanned aerial vehicle can be automatically transformed and additionally installed conveniently.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a three-axis stable platform for unmanned aerial vehicles. Background technique [0002] War is the number one driving force for the development of UAVs. Since the 20th century, as the application potential of UAVs in military, civilian and other fields has been gradually tapped, UAV technology has developed rapidly. In recent years, as drones have become more and more well-known to the public, they have entered the lives of ordinary people. The UAV pan / tilt is a mechanical component installed on the UAV to carry cameras and other shooting equipment. At present, the general UAV pan / tilt can satisfy the rotation of the camera with three degrees of freedom, and each axis is equipped with a The gimbal motor, when the drone is tilted, will cooperate with the gyroscope to add power in the opposite direction to the corresponding gimbal motor, so as to prevent the came...

Problems solved by technology

However, traditional UAV gimbals are either complex in structure, difficult to process, and heavy in quality, leading to a sharp increase in the cost of gimbals, or the structure is too simple to ensure the stability and functionality of gimbal work, and at the same time, the safety is poor
