MULTI-ROTOR UNMANNED AERIAL VEHICLE

WIPO Patent Application WO/2023/082292

A1

A multi-rotor unmanned aerial vehicle (UAV), comprising: a center body (10); a landing frame (11), which is located below the center body (10); two pairs of arms (12), which are rotatably connected to the center body (10), so as to achieve an unfolded state and a folded state of the arms (12); and multiple rotor devices (13), which are respectively mounted on the two pairs of arms (12), the rotor devices (13) being used for providing flight power, and the center body (10) being obliquely arranged relative to a landing plane of the landing frame (11). In the unfolded state, the arms (12) are radially unfolded relative to the center body (10); and in the folded state, each pair of arms (12) is in an up-down folded state, an arm (12) that is connected to a lower side of the center body (10) is located below, and an arm (12) that is connected to a higher side of the center body (10) is located above. The present multi-rotor UAV has a relatively low overall height and relatively small volume after being folded, which facilitates carrying, transporting and storing the multi-rotor UAV.
