Abstract
The invention discloses a novel folding rotor arm structure of an unmanned aerial vehicle. The structure comprises the unmanned aerial vehicle and a rotor of the unmanned aerial vehicle, wherein a cylindrical telescopic rod is connected to the rotor and connected with a bushing through a spring, one end of the bushing is connected with the unmanned aerial vehicle, the other end is open and matched with the telescopic rod, and the telescopic rod can move freely in the bushing in the axial direction of the bushing; a clamping handle perpendicular to the telescopic rod is further arranged on the telescopic rod, an opening matched with the clamping handle is formed in the bushing and is in the same direction with extension of the bushing. When the unmanned aerial vehicle collides with obstacles, the spring is compressed under stress to prevent the rotor arm from being damaged, and the clamping handle can only move along the opening, so that the problem of rotation of the telescopic rod in the bushing is solved. The novel folding rotor arm structure has the advantages that in the event of a collision, the rotor is prevented from being damaged by compressing the spring; storage is facilitated by the aid of the folding structure.

With aviation, office issues《Civilian push-button aircraft system driver management temporary provisions》, the people are responsible for by Chinese AOPA associations
With the related management of unmanned plane.According to《Regulation》, inland of China unmanned plane is operated can be divided into 11 according to type size, flying area
The situation of kind, wherein only more than 116 kilograms of unmanned plane and more than 4600 cubic metres of dirigible fly by civil aviaton in fusion spatial domain
Office's management, remaining situation, including other flights including day by day popular miniature aerial photography aircraft, managed by employer's organization,
Or be voluntarily responsible for by manipulator.
Existing unmanned plane based on fixed rotor, if collided with barrier during flight, pole
Easy damaged rotor.
The content of the invention
The technical problem to be solved be existing unmanned plane based on fixed rotor, flight process
In if collided with barrier, easily damage rotor, it is therefore intended that provide a kind of new unmanned plane folding rotor arm configuration,
Existing unmanned plane is solved based on fixed rotor, if collided with barrier during flight, is easily damaged
Hinder the problem of rotor.
The present invention is achieved through the following technical solutions：
A kind of new unmanned plane folding rotor arm configuration, including the rotor of unmanned plane and unmanned plane, connect on the rotor
There is expansion link, the expansion link is cylinder, and expansion link passes through spring and telescopic joint, described sleeve pipe one end connection unmanned plane,
Another end opening is matched with expansion link, and expansion link can also set in sleeve pipe along sleeve pipe axial free movement, the expansion link
The card handle perpendicular to expansion link is equipped with, the opening matched with card handle is provided with described sleeve pipe, the opening direction prolongs with sleeve pipe
Stretch direction identical.Traditional fixed rotor is improved, using sectional design, by traditional rotor arm replace with sleeve pipe with
The attachment structure of expansion link, is attached using spring, and when unmanned plane runs into obstacle to collide, spring stress compression keeps away
Exempt from rotor arm to be damaged, while card handle can only carry out moving the problem that expansion link rotates in sleeve pipe that avoids along opening.
The spring is in all the time compressive state.I.e. under normal circumstances, expansion link outreach from sleeve pipe is maximum, just
Need not manually adjust when often using, in the air collision rift rotor arm cannot reset to it also avoid unmanned plane.
Length of the length of described sleeve pipe more than rotor (5).Rotor is avoided to be collided by sending with fuselage again after crash compresses.
The opening (101) is also axially prolonged along sleeve pipe (1) wall away from one end of expansion link (2) perpendicular to sleeve pipe (1)
Stretch.When receiving to unmanned plane, card handle press-in sleeve pipe can be then threaded into extension lock near one end of unmanned aerial vehicle body
It is fixed, wing is folded.
The end of opening (101) extension axially carries out extension formation card along along sleeve pipe (1) wall parallel to sleeve pipe (1)
Mouth (102).Arranging card handle when bayonet socket ensure that wing-folding in extension will not skid off.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of new unmanned plane folding rotor arm configuration of the present invention, rotor is avoided when colliding by compression spring
It is impaired；
2nd, a kind of new unmanned plane folding rotor arm configuration of the present invention, with foldable structure, is easy to storage.
