Multi-rotor aircraft and airframe and extension module of multi-rotor aircraft

Abstract

The invention discloses an airframe of a multi-rotor aircraft. An extension connection device is arranged on the airframe. An external extension module extends from the airframe through an extension connection device. The airframe has the beneficial effect that the extendibility of the airframe is improved. The invention further discloses the extension module matched with the airframe and used for the multi-rotor aircraft. The extension module is provided with a connection part capable of being connected with the extension connection device on the airframe. The extension module has the beneficial effects of achieving interface uniformity of the external extension module and improving reusability. The invention further discloses the multi-rotor aircraft adopting the airframe and the extension module, and an extendable and modular aircraft is obtained.

Description

technical field [0001] The invention relates to a robot and its accessories, in particular to a multi-rotor aircraft and its frame. Background technique [0002] Multi-rotor aircraft is a kind of robot that has emerged in recent years. It is widely used in aerial photography, entertainment, and monitoring fields because of its convenient manipulation, simplicity, practicality, and low price. [0003] The quadrotor aircraft uses four rotors as the direct power source for the flight. The rotors are symmetrically distributed in the front, rear, left and right directions of the body. The four rotors are at the same height plane, and the structures and radii of the four rotors are the same. 3 Rotate counterclockwise, rotor 2 and rotor 4 rotate clockwise, the four motors are symmetrically installed on the bracket end of the aircraft, and the flight control computer and external equipment are placed in the middle space of the bracket. [0004] The patent application with the Chine...
