The invention is described in detail below by way of example with reference to the accompanying drawings.
Example 1:
the embodiment provides a but arm double-deck staggered arrangement, horizontal folding six rotor unmanned aerial vehicle, adopts layering, staggered arrangement to arrange, can reduce volume and weight after six rotor unmanned aerial vehicle are folding by a wide margin, improves its portability.
This six rotor unmanned aerial vehicle global design thinking do: divide into two-layer about six horn, three horn of every layer is along the outer circumference even interval distribution of unmanned aerial vehicle host computer frame 4, and six whole also along the outer circumference even interval distribution of host computer frame 4 of horn on upper and lower layer, and every layer of three horn is 120 degrees along unmanned aerial vehicle host computer outer fringe from this, and the adjacent horn of upper and lower layer is 60 staggered arrangement.
As shown in fig. 1-2, the six-rotor drone includes: the device comprises a main frame 4 and six arms uniformly distributed at intervals along the circumferential direction of the main frame 4; the six arms are divided into an upper layer and a lower layer along the axial direction of the main frame 4 (so that the six foldable propeller blades 2 are not completely positioned on the same plane), and the three arms of each layer are arranged at intervals of 120 degrees; and the three machine arms on the upper layer and the three machine arms on the lower layer are uniformly distributed at intervals, so that two adjacent machine arms are respectively positioned on the upper layer and the lower layer on the whole, and the interval between the two adjacent machine arms is 60 degrees.
Six horn lengths equal, connect a propeller blade 2 on every horn, the horn is collapsible, includes: a foldable long arm 5, a horn folding joint 3 and a short arm 6; one end of the short arm 6 is fixedly arranged on the host frame 4, the other end of the short arm is connected with one end of the foldable long arm 5 through the horn folding joint 3, and the foldable long arm 5 is folded in a plane through the horn folding joint 3; the propeller blades 2 are arranged at the other end of the foldable long arm 5; the motor 1 is fixed on the foldable long arm 5 through a motor base, and the power output end of the motor 1 is connected with the propeller blades 2 and used for driving the propeller blades 2 to rotate. When the size structure of the machine arm is designed, the lengths of the foldable long arm 5 and the foldable short arm 6 are determined according to the compact principle that the three machine arms on the same layer are just compatible after being folded.
Among the six propeller blades 2 of the unmanned aerial vehicle, three propeller blades 2 connected with the three arms positioned on the upper layer face upwards, and three propeller blades 2 connected with the three arms positioned on the lower layer face downwards; the six propeller blades 2 adopt three upward and three downward mounting structure forms, so that the larger load can be borne on the premise that the center of gravity of the upper half part of the main frame 4 is positioned at the center of the machine body.
Compare six rotor unmanned aerial vehicle vertical folding's of tradition mode, this unmanned aerial vehicle's horn adopts in the plane folding mode, the collapsible long arm 5 of every horn can be around its butt joint end horizontal rotation settlement angle with short arm 6 under the effect of horn folding joint 3, realize the folding of horn, as shown in fig. 3, when being in fold condition, be in the three horn of same floor and transversely rotate in its self place horizontal plane and fold into the triangle form, reduce space size area occupied under unmanned aerial vehicle packing and transportation condition from this.
The specific comparative analysis is as follows:
the specific structural dimension of this unmanned aerial vehicle in this example is: the diameter a of the overall machine radial outline 7 is 1694mm when the overall machine radial outline is unfolded, the height b of the main machine body longitudinal outline 10 is 0.17a 288mm when the overall machine radial outline is unfolded (or folded), the diameter d of the overall machine radial outline 9 is 0.46a 779mm when the overall machine radial outline is folded, and the arm length c of the foldable long arm 5 is (a-d)/2 is 457 mm. In this example, two adjacent propeller blade contours 8 overlap 20mm in plan view when in operation (i.e., when deployed). Therefore, the occupied area of the unmanned aerial vehicle in the unfolding state is as follows: s ═ pi (a/2)2=2.254×106mm2=2.254m2。

(2) Because six rotor unmanned aerial vehicle's of tradition horn is folding perpendicularly, the horn length c' after its folding back cylindrical profile highly be the extension, the bottom surface is the same with this embodiment, then folding back appearance profile volume is:
V’=π(d/2)2×c’=π(779/2)2×487=2.321×108=0.2321m3is 1.69 times of the volume of the folded profile of the unmanned aerial vehicle (or can be understood as adopting the scheme in the embodiment)The volume of the folded same-specification six-rotor unmanned aerial vehicle can be reduced by 41 percent.
(3) Because unmanned aerial vehicle needs extension horn in the present embodiment is compared to traditional six rotor unmanned aerial vehicle of folding perpendicularly, corresponding complete machine weight also increases to some extent.
The same kind of comparison unmanned aerial vehicle folding back main engine body longitudinal shape outline line 11 is shown in fig. 6.
