Description

technical field [0001] The invention relates to a fuselage conductive structure of an unmanned aerial vehicle and a manufacturing method thereof. Background technique [0002] Unmanned aircraft, referred to as "drone" for short, and "UAV" for English abbreviation, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned parawing aircraft, etc. [0003] The existing common electric multi-rotor UAVs are all powered by lithium batteries. When the power supply system supplies power to the power motor on the outermost edge of the machine arm, it needs to connect long and thick power wires. It is difficult to avoid the problem of self-heaviness in the traditional fuselage structure. In the case of the same task load weight...
