Embodiment Construction

[0052] Such as Figure 1-5 As shown, the rotor UAV with automatic center of gravity adjustment in this embodiment includes: a body 1, eight groups of rotor assemblies 2 evenly distributed in the circumferential direction on the body 1, and a detection device and a translation mechanism 4 at the bottom of the body 1.

[0053] The rotor assembly 2 includes a transmission shaft 21 connected to the machine body 1 and a rotor 22 installed at the free end of the transmission shaft 21 .

[0054] The detection device includes four support assemblies 3 vertically erected below the body 1 to jointly support the body so as to keep the body level and test the support force at the same time. The compression spring 33 and the spring pressure detection module (not shown in the figure) between the outer sleeves, the four inner sleeves 31 are respectively fixed on the transmission shaft 21 of the rotor assembly 2 at intervals, and the inner sleeves 31 are clamped and fixed on the transmission ...

Abstract

The invention provides a rotor-type unmanned aerial vehicle automatically adjusting a gravity center after loading and an adjustment method. The rotor-type unmanned aerial vehicle includes a machine body provided with a rotor assembly, the bottom of the machine body is provided with a testing device for supporting the machine body to test the weight and the gravity center of the machine body and a translational mechanism connected with the machine body; the translational mechanism comprises a mobile output end for fixing a load. According to the rotor-type unmanned aerial vehicle automatically adjusting the gravity center and the adjustment method, a gravity center position of the unmanned aerial vehicle is controlled through installation of the testing device and the translational mechanism on the machine body, so that the unmanned aerial vehicle can perform smooth taking-off and landing and safe landing, and the security of the unmanned aerial vehicle is improved; and the adjustment method is simple in process, enables detection and adjustment to be carried out from time to time, and is applicable to a working condition that requires to frequently modify the machine body.

Description

technical field [0001] The invention relates to a small unmanned aerial vehicle, in particular to a rotor type unmanned aerial vehicle for automatically adjusting the center of gravity and an adjustment method. Background technique [0002] At present, small drones at home and abroad have been widely used in civilian and military fields, such as disaster monitoring in disaster areas, aerial photography of TV stations, power line inspection, weather detection, target detection, etc. [0003] Small UAVs mainly include unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, and unmanned umbrella-wing aircraft. It is cheap and widely used. More importantly, it does not require a launch system, can take off and land vertically, can hover more freely, and has good flight flexibility. It can fly at various speeds and with various flight profiles. The rotor UAV mainly includes a body and a rotor assembly fixed on the body to drive the f...
