The pursuit of technology has been developed in the convenience degree for pursuing and using and carrying by individually pursuing performance indicator.It is existing to have
The blade of major diameter is generally arranged in the multi-rotor unmanned aerial vehicle that load-carrying requires on the body construction.Meanwhile at present existing more rotors without
It is man-machine mostly there is structure is complicated, volume is big, the component that loads is more；It is not readily portable: not foldable, do not have to easily worn part
It is protected；The disadvantages of not easy to disassemble.
The Chinese utility model that notification number is CN204937480U discloses a kind of multistage folded wing component and has it
Aircraft.Endpiece wing the last period wing connected to it of the multistage folded wing component passes through Worm Wheel System
Mechanism connection, and by Worm Wheel System mode to its last period wing direction folding movement；Each interlude wing is equal
It is connect by Worm and worm-wheel gearing with its last period wing, and by Worm Wheel System mode to its last period wing side
To folding movement；The first section wing is connect by Worm and worm-wheel gearing with the fuselage, and passes through Worm Wheel System
Mode is to fuselage direction folding movement.There is the wing in flight course and main body mechanisms for the locking of worm and gear form
The problem of connecting unstable situation, being especially in the presence of wing flutter aggravation.
Therefore, it is necessary to which locking mechanism in place is additionally arranged, effect is to keep the movable rudder face of folding accurate in predetermined position
Positioning, and reliably lock, and bear and transmit service load.Conventional locking mechanism in place generally uses spring detent,
And corresponding pin hole is designed on aerofoil connector.When aerofoil is in folded state, lock pin keeps pre-tightening under spring force
State is slided along aerofoil joint surface to pin hole position at the top of lock pin, under spring force lock pin during aerofoil expansion
Bullet locks aerofoil into pin hole.In flight course, the spring of such locking mechanism needs to overcome the service load of wing, therefore,
In Series Pilotless Aircraft, with the increasing of unmanned plane size, service load is inevitably enlarged, and the specification of spring even more increases therewith
Greatly.But the variation of the specification of standard spring and the structure size variation of unmanned plane are not same standard tolerance sequence of values
Variation necessarily brings the confusion for selecting stake spring.Meanwhile the increase of spring specification necessarily brings being significantly increased for weight, with
Light-weighted design requirement on unmanned plane is a pair of contradiction that can not be reconciled.Therefore, it is necessary to seek a kind of new locking in place
Device realizes the accurate positionin of wing.
Utility model content
The purpose of this utility model is that: in view of the above-mentioned problems, providing a kind of unmanned plane folded wing expands in place locking
Structure, the modular construction is simple, convenient for using on tandem product, and meets the light-weighted design requirement of unmanned plane.
The technical solution adopted in the utility model is as follows:
A kind of unmanned plane folded wing expands in place locking structure, including body, and blade fixed arm, paddle are provided on body
Mounting hole is offered on leaf fixed arm, main shaft is arranged in mounting hole, and wing is fixed on main shaft, and is also opened up on blade fixed arm
There is location hole, the tail end of wing is provided with pin hole, and positioning hole is arranged with positioning pin, and positioning pin one end is provided with plectrum, main shaft
One end on be provided with card slot compatible with plectrum.
Further, plectrum is set as fan-shaped eccentric plectrum, and plectrum is fixedly connected with positioning pin.
Further, main shaft is set as punching bolt.
Further, gasket is fixed on the nut of main shaft, there are certain interval, gaps between gasket and blade fixed arm
Equal to the thickness of plectrum.
Further, sleeve is also arranged on main shaft, one end of sleeve is connect with gasket, and the other end and blade of sleeve are solid
Fixed arm connection；The thickness of sleeve is equal to the thickness of plectrum.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, in the utility model, when unmanned plane is increased in size, the size of main shaft, i.e. enlarged diameter, the present embodiment are determined
Position pin size, i.e. diameter also increase accordingly, and the thickness of plectrum increases, and three's stress model does not change, i.e., dimension scale is fixed
's.And when selecting spring, standard spring has the variation numerical value of itself.The form of spring detent compared to the prior art, this reality
The structure for applying example is simpler, and size amplification is easier to meet the standard of tolerance numerical value of unmanned plane structure size, exists without worry
The puzzlement that spring bring weight is considered, the space interference of spring arrangement is considered is selected during this.Therefore, the present embodiment discloses
Structure can readily be used in the unmanned plane of plurality of specifications, to realize the seriation of unmanned plane, modularization, standardization, be convenient for
To marketing, to reduce design, production cost.
2, in the utility model, wing in high-speed rotation process, eccentric plectrum under the influence of centrifugal force, direction always
The direction of wing blade tip, in this way, eccentric plectrum is stuck in always in the card slot on main shaft, so that eccentric plectrum be avoided to be detached from card
Slot, thus keep card slot press always positioning pin locking and positioning.Namely it eliminates existing in the prior art various multiple
Miscellaneous spring, worm gear structure.When wing-folding, eccentric plectrum is stirred, eccentric plectrum is freed from the card slot of main shaft, i.e.,
Eccentric plectrum can be transferred to, eccentric plectrum is detached from from card slot, then can extract positioning pin.This reality adopted this technical solution
A clever structure is applied, design requirement complicated on unmanned plane is met using simple eccentric structure, compared to springlock pin-shaped
Formula, the structure of the present embodiment is relatively reliable in high-speed flight, and easy to operate, is easy to use.
3, in the utility model, fluting can destroy shape, the stress of main shaft on main shaft, therefore below the nut of main shaft
A gasket is fixed, existing annular space is card slot between gasket 7 and the surface of blade fixed arm.
