Unmanned aerial vehicle with telescopic propeller arms and telescopic landing legs

Abstract

The invention discloses an unmanned aerial vehicle (UAV) with telescopic propeller arms and telescopic landing legs. The structure of the UAV comprises a UAV body, a telescopic adjustment connecting frame, a first propeller, blades, the landing legs, a second propeller, a second telescopic adjustment connecting frame, a third propeller and a fourth propeller, wherein the telescopic adjustment connecting frame is perpendicularly connected to the left end surface of the UAV body; the left end surface of the telescopic adjustment connecting frame is movably connected with the first propeller; the upper end surface of the first propeller is perpendicularly connected with a spiral rotating shaft; the corresponding blades are perpendicularly connected to the outer surface of the spiral rotating shaft; and the left end of the telescopic adjustment connecting frame is downwardly and movably connected with one of the landing legs. The UAV with the telescopic propeller arms and the telescopic landing legs can freely and flexibly adjust the state of the propeller arms and the landing legs according to actual needs, thereby ensuring the on-time and efficient accomplishment of corresponding tasks and effectively improving the practical performance of the UAV.

Description

technical field [0001] The invention is an unmanned aerial vehicle with retractable paddle arms and a tripod, which belongs to the technical field of unmanned aerial vehicle manufacturing. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. Drones are often better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protection, micro selfies, express delivery, disa...
