Part is the travelling gear engaged with center ring.
As a further improvement on the present invention：The travelling gear is two, and the week side of boss of center ring is installed in symmetry shape,
And be fixed on bottom plate.
As a further improvement on the present invention：Region on the bottom plate between center ring and bottom plate outward flange is provided with energy
Enough accommodate the space of all horns.
As a further improvement on the present invention：Being shaped as of the bottom plate is equipped with receiving one at polygon, each edge
The space of horn.
Compared with prior art, the advantage of the invention is that：
1st, the propeller folding device for unmanned plane of the invention, simple and compact for structure, small volume, gathering effect are good,
The motion of all horns is so all in the region that each horn can turn to bottom plate completely when carrying out folding to rotate
Horn will not be exposed, to ensure optimal portability.That is, the present invention will cause the consumer level unmanned plane of the type most
Folding and unfolding is realized in limits, in the case where not sacrificing stability and basic function, real portability is realized.
2nd, the propeller folding device for unmanned plane of the invention, is driven, rotational angle can using motor mate gear
To realize autonomous control by software, it can reach and preferably draw deployed condition in, so that the folding and unfolding of whole mechanism is realized, and
Ensure stability.
3rd, the propeller folding device for unmanned plane of the invention, the design of center ring is in only two driving sources
In the case of, it is ensured that the design of four power output synchronisms, this will cause four horn uniform forces and coordination is synchronous.

Embodiment
The present invention is described in further details below with reference to Figure of description and specific embodiment.
As depicted in figs. 1 and 2, the propeller folding device for unmanned plane of the invention, including bottom plate 6, more than three
Horn 1, center ring 5, driving part（Do not show in figure）And gear transmission part 3, the horn 1 of more than three is circumferentially
Be sequentially arranged on bottom plate 6, one end of horn 1 is articulated with bottom plate 6 by axle and can rotated around pin joint, horn 1 it is another
End is used for installing unmanned plane propeller component.Center ring 5 is located at the middle part of bottom plate 6, and gear transmission part 3 is installed on center ring 5
The week side of boss, the driving cog for coordinating with gear transmission part 3 is provided with center ring 5, driving part passes through gear drive portion
Part 3, which is rotated, rotates center ring 5.Region on bottom plate 6 between center ring 5 and the outward flange of bottom plate 6 is all provided with that can accommodate
The space of horn 1.Connecting rod 2 is each provided between horn 1 and center ring 5, i.e. one end of connecting rod 2 is articulated with horn 1, connecting rod
2 other end is articulated with center ring 5.When center ring 5 is rotated, will drivening rod 2 move, so as to pass through connecting rod 2
Drive horn 1 to realize to be synchronized with the movement, reach the purpose that horn 1 is folded or opened.Because the motion of horn 1 is rotates, carrying out
Each horn 1 can be turned in the region of bottom plate 6 completely during folding, and so all horns 1 will not be exposed, optimal to ensure
Portability.
In the present embodiment, several leads 4 are provided with center ring 5（This example is 2）, lead 4 include thrust
Axle and central shaft, center ring 5 are clamped by several thrust shafts of periphery, center ring 5 is merely able to the free degree of parallel rotation.
