Embodiment 1

[0048] Such as figure 1 , 4 As shown in 21, what this embodiment provides is a multi-rotor helicopter folding system, which is a three-rotor folding system. The specific structure is described in detail with the structure in the three-rotor as a representative. And the cantilever fixing seat 18 that is respectively arranged on the triangular support, the middle hole formed by the interlocking of the cantilever fixing seat 18 and the cantilever positioning seat 20 is provided with a cantilever 1, and the cantilever fixing seat 18 and the cantilever positioning seat 20 A pin hole 19 is provided on the cantilever 1. One end of the cantilever 1 is provided with a cantilever folding seat 14. Two folding reference shafts 13 are oppositely provided on the outside of the cantilever folding seat 14. One side of the folding reference shaft 13 is provided with a folding Worm wheel 3, the bottom of the folding worm wheel 3 is provided with a first travel limit sensor 17, the folding worm...

Embodiment 2

[0057] This embodiment has been improved on the basis of Embodiment 1, and other structures are the same, the difference is: as figure 2 As shown, the quadrotor device described in this embodiment includes a folding device arranged at 45° on a circular support.

Embodiment 3

[0059] This embodiment has been improved on the basis of Embodiment 1, and other structures are the same, the difference is: as image 3 As shown, the six-rotor device includes a folding device arranged on a circular support at 60°, and the rotors are arranged in layers up and down.

Abstract

The invention relates to the technical field of manufacture of helicopters, in particular to a multi-rotor helicopter folding system. According to the multi-rotor helicopter folding system, the reliability of folding and unfolding of helicopter wings is improved through combination of a worm and gear structure with a control unit and a relay. The provided multi-rotor helicopter folding system comprises a folding device adopting a three-rotor, four-rotor or six-rotor structure. The multi-rotor helicopter folding system has broad applications such as military, civil use, agriculture, payload, unmanned aerial vehicles, model airplanes and the like.

Description

technical field [0001] The invention relates to the technical field of aircraft manufacturing, in particular to a multi-rotor helicopter folding system. Background technique [0002] Vertical take-off and landing aircraft currently on the market mainly include electric multi-rotors, direct-drive multi-rotors, single-rotor helicopters and coaxial twin-screw helicopters. [0003] Chinese patent CN201385780Y discloses a propeller on an aircraft, especially a new type of foldable and telescopic propeller. The propeller includes a rotating shaft and blades mounted on the rotating shaft. It is characterized in that there are There is an auxiliary chute at the root of the telescopic blade, the telescopic blade is set in the chute at the end of the main blade, the main blade is set in the auxiliary chute of the telescopic blade, the main blade and the rotating shaft chain connection. The utility model can realize the change of the rotation diameter of the blade by installing the r...
