Problems solved by technology
Small multi-rotor drones can judge whether the center of gravity of the drone is in the center by grasping two symmetrical points of the center of the multi-rotor drone with both hands. Large multi-rotor drones need two people to cooperate to determine whether the center of gravity is appropriate, and It is very inconvenient to judge whether the center of gravity is suitable after each adjustment

Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0022] Such as figure 1 As shown, the auxiliary device in this embodiment includes: a slider 1 with a pressure sensor, a connecting rod 2, a telescopic tripod 3, a tripod limit connector 4, a connecting rod limit connector 6, a spirit level 5, a MCU with two buzzers 7.
[0023] The slider 1 with the pressure sensor can slide horizontally on the connecting rod 2.
[0024] Four connecting rods 2 form a diamond-shaped support frame, and two adjacent connecting rods 2 are hinged. One of the connecting rods 2 has a connecting rod limit connector 6, which can fix the four connecting rods 2 in a square shape.
[0025] The connecting rod limit connector 6 has a plurality of locating grooves, and the other adjacent connecting rod 2 is provided with a locating pin cooperating with the locating groove, and the locating pin is snapped into the locating groove, and the ...

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.
Description
technical field [0001] The invention relates to an auxiliary device for adjusting the center of gravity, in particular to an auxiliary device for adjusting the center of gravity of a multi-rotor drone. Background technique [0002] Drone technology has advanced by leaps and bounds in recent years. Due to its low cost, good maneuverability, strong survivability, and no risk of casualties, UAVs occupy an extremely important position in modern military warfare and have a very broad prospect in the civilian field. The current UAVs mainly include fixed-wing UAVs and rotary-wing UAVs. [0003] In order to ensure that the center of gravity of the UAV is in a balanced position, the existing patent document CN204473120U provides a UAV center of gravity adjustment mechanism, which is provided with a slide bar mechanism, a slide frame and bolts; the slide bar mechanism is provided with a slide bar and a connection block, the slide bar is connected with the fuselage through the connec...
