Abstract

The invention relates to a self-stabilizing platform for high-attitude shooting of an unmanned aerial vehicle. The self-stabilizing platform comprises a fixing machine frame, wherein the fixing machine frame comprises a lower platform; a transmission shaft is mounted at the middle part of the upper end surface of the lower platform through a bearing; a transmission gear is mounted at the middle part of the transmission shaft through a key, and is meshed with six transmission branched chains in an axial direction; the upper ends of six driving shafts of the six transmission branched chains are respectively connected with a supporting platform through the bearings; the middle part of the supporting platform is connected with the transmission shaft through the bearings; six supporting columns are uniformly welded to the lower end surface of the supporting platform in the axial direction, and the lower end surfaces of the six supporting columns are respectively mounted on the lower platform; the upper end of the transmission shaft is connected with a transmission screw rod through a coupling; a transmission sliding block is mounted at the middle part of the transmission screw rod in a threaded connection manner. According to the self-stabilizing platform disclosed by the invention, a function of stable rise-and-fall aerial shooting of the unmanned aerial vehicle can be realized, and the self-stabilizing platform has the advantages of being simple in structure, good in stability quality of the mechanical structure, good in rise-and-fall aerial shooting performance, high in working efficiency and the like.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a self-stabilizing platform for high-altitude aerial photography of unmanned aerial vehicles. Background technique [0002] The pan / tilt is a supporting device used to install and fix the camera equipment in the monitoring system. It does not directly receive the image, but the pan / tilt controls the rotation direction of the camera or other equipment. The UAV aerial photography platform belongs to the category of the platform, which is mainly used in practical aerial photography such as construction planning, engineering survey, disaster survey, emergency rescue and disaster relief, traffic condition monitoring and high-altitude cruise. [0003] In the actual application process, due to the continuous change of the UAV's own attitude during the flight and the influence of external weather factors, a certain amount of vibration is brought to the entire UAV body, which serio...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a self-stabilizing platform for high-altitude aerial photography of unmanned aerial vehicles, which can solve the problem of poor stability of the mechanical structure of the existing unmanned aerial vehicles and hysteresis in the adjustment of the electronic detection system during the aerial photography of the existing unmanned aerial vehicles. The jitter caused by external weather factors leads to poor aerial photography effects, and the inability to rigidly adjust the lifting angle results in small aerial photography viewing angles and low work efficiency. This invention uses a 6-SPS parallel mechanism with good dynamic response, high rigidity, large carrying capacity, good stability and motion accuracy. It has the advantages of simple structure, good stability of its own mechanical structure, good performance of lifting aerial photography and high work efficiency.
