Embodiment Construction

[0024] Such as figure 1 , 2 As shown, the portable quadrotor aircraft with replaceable rotor arms includes a fuselage 1, four rotor arms 2 and four rotors 3, and the four rotor arms 2 are symmetrically arranged at the four corners of the fuselage 1, and the four rotors The arm 2 and the fuselage 1 are combined into a "ten"-shaped structure, and the four rotors 3 are respectively arranged on the four rotor arms 2. The connecting ends of the rotor arms 2 are provided with threaded joints 4, and the rotor arms 2 are connected to the Body 1 threaded connection.

[0025] Of course, it also includes spare rotor arms with different load rotors. According to the weight of different equipment installed on the fuselage, different rotor arms are docked and installed to ensure that the aircraft has sufficient power.

[0026] The bottom of the rotor arm 2 is provided with a tripod 5, and the four rotor arms 2 are also provided with flashing lights.

[0027] The fuselage 1 is provided wi...

Abstract

The invention discloses a rotor wing replaceable portable four-rotor wing aircraft which comprises a plane body, four rotor wings and four rotors, wherein the four rotor wings are symmetrically arranged at four corners of the plane body; the four rotor wings and the plane body form a cross section; the four rotors are respectively arranged on the four rotor wings; the four rotor wings are in detachable connection with the plane body. Due to the detachable connection of the rotor wings and the plane body, when the rotor wing replaceable portable four-rotor wing aircraft is not used, the rotor wings can be dissociated from the plane body, so that the space occupied by the whole plane body can be reduced, and the rotor wing replaceable portable four-rotor wing aircraft can be conveniently carried over or transported; due to the detachable connection mode, spare rotor wings with rotors of different loads can be abutted and mounted according to different demands, so that the detachable connection is significant, and possibility is provided for replacing spare power equipment with different loads.

Description

technical field [0001] The invention relates to an aircraft, in particular to a quadrotor aircraft. Background technique [0002] In the prior art, both the rotor arm and the fuselage adopt an integrated design, so there are the following defects: one is that the volume is relatively large and takes up a lot of space, so it is inconvenient to carry and transport; the other is that the load of the power equipment is determined, Different power equipment cannot be changed according to the actual body weight. [0003] The State Intellectual Property Office published a patent with the publication number CN203294313U on November 20, 2013, and the patent name is a police four-rotor unmanned aerial vehicle. cover and GPS, power equipment is provided at the center of the lower end of the machine arm, and the GPS is connected to the power equipment; propellers are arranged on the outer end of each machine arm, and each propeller is connected with a corresponding motor respectively; ...
