Auxiliary device for adjustment of center of gravity of multi-rotor unmanned plane

The invention discloses an auxiliary device for adjustment of a center of gravity of a multi-rotor unmanned plane. The auxiliary device comprises a polygonal support frame formed by successive connection of a plurality of connecting rods, telescoping foot stands hinged to the connecting rods, sliding blocks, comparators, and prompting devices. The sliding blocks are provided with pressure sensors and the sliding blocks and the connecting rods are in a sliding fit relation; the comparators are used for comparing compressed data of the sliding blocks arranged on each two opposite connecting rods; and the prompting devices are started according to pressure difference signals outputted by the comparators. According to the invention, adjustment of the center of gravity of the large multi-rotor unmanned plane can be realized; whether the center of gravity is proper can be determined in real time according to the buzzing frequency of the corresponding buzzer. The device with a simple structure can be folded and thus can be carried conveniently and is suitable for a rugged ground environment.
