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 ...

Abstract

The invention discloses an auxiliary device for adjusting the center of gravity of a multi-rotor UAV, which comprises a polygonal support frame formed by connecting a plurality of connecting rods sequentially, a telescopic tripod hinged on the connecting rods, slidingly fitted along each connecting rod and equipped with The slide block of the pressure sensor, the comparator used for comparing the pressure data of the slide block on the two opposite connecting rods, and the prompter activated according to the output pressure difference signal of the comparator. The invention can realize the adjustment of the center of gravity of a large multi-rotor UAV by a single person, and can judge whether the center of gravity is suitable through the sound frequency of the corresponding buzzer in real time.

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 patent literature with the existing publication number CN 204473120 U 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 connecting block, the sliding rod is connected with...
