Multi-rotor aircraft

Abstract

The invention relates to a multi-rotor aircraft. The multi-rotor aircraft comprises a base and a flight mechanism, wherein the base is made from a light material; a through air flow channel is formedin the base; the lower surface of the base is a plane or a smooth curved surface; when an optional medium surface falls to the ground, the lower surface of the base is in point contact or surface contact with the medium surface; the flight mechanism is connected with the base and comprises a plurality of rotors which are distributed at intervals; and the lower end surface of each rotor is higher than the lower surface of the base. By arrangement of the light base, the lower surface of the base and the medium surface have enough contact points or certain contact area, and therefore, the multi-rotor aircraft cannot roll over on an oblique or uneven road surface, can float on the water surface or can stay on marsh. The multi-rotor aircraft can adapt to various outdoor complicated environments, and can reliably park on an optional medium surface, the flexibility is improved, and the application range or scene is expanded.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to a multi-rotor aircraft. Background technique [0002] Traditional drones are equipped with landing gear at the bottom for a smooth landing, but in practice, drones are usually used outdoors and often land in complex environments, such as slopes and uneven ground (laid by stones or gravel), river beaches, swamps, water surfaces, etc. In such complex environments, the landing gear will rollover due to uneven ground, or will be stuck in the cracks of the stones, or directly submerged in the mud, or Falling into the water makes it impossible to start the drone operation again, and even leads to damage and destruction of the drone, which affects the efficiency of use. Contents of the invention [0003] In order to enable the UAV to adapt to the complex environment, it can be parked stably and reliably on the surface of complex media outdoors, which is conducive to taking off again. ...
