Description
Technical field
The utility model relates to unmanned plane field more particularly to a kind of wing stable rotation and position it is collapsible nobody
Machine.
Background technique
In the unmanned plane of cartridge type emission-type, since horizontal space is very narrow, when unmanned plane is in cylinder, need wing
It folds.It after unmanned plane transmitting flies out cylinder, and needs wing energy Automatic-expanding and is in the locked position, to be provided for unmanned plane
Lift, to guarantee the normal flight of unmanned plane.Folded wing has many advantages, such as that lateral dimension is small, fills convenient for box type storing, transport,
Unmanned plane especially suitable for cartridge type emission-type.
For cartridge type emission-type unmanned plane, the folding of wing and expansion locking mechanism need to meet and connect reliable, mechanism letter
The conditions such as single, expansion is rapidly, locking is secured, light-weight, small in size, aerodynamic configuration is good.Wing-folding mode master common at present
There are wound formula, submersible, tail stacked, longitudinal folding formula, laterally folded formula etc..It is mostly spring mechanism that locking structure, which is unfolded,
The gaseous-pressure system that useful hydraulic system or priming system are formed.In the environment that vibration level is larger or other are harsh, at present
Solution exist fold and and expansion lock function it is incomplete, be easy to loosen and lead to the defects of ineffective.
The patent of invention that number of patent application is CN201711056963.3 discloses a kind of wing-folding locked component and nothing
It is man-machine, it is related to air vehicle technique field.A kind of wing-folding locked component, including wing, fixing seat and fold mechanism.It folds
Mechanism is connect with fixing seat, wing simultaneously, is in folding or unfolded state to control wing relative to fixing seat.Fixing seat includes
Main body, main body include spaced mounting portion and connector.Wing includes wing-body and wing shaft.The two of wing-body
End is connect with wing-body, mounting portion respectively.Connector is equipped with elastic spacing portion close to one end of wing-body, and wing-body is set
There are location hole, limiting section and location hole cooperation.A kind of unmanned plane, including above-mentioned wing-folding locked component.Wing-folding locking
Component can be realized folding and expansion and the lock function of unmanned plane wing, without using other power sources.
But the fold mechanism of above-mentioned unmanned plane is connect with fixing seat and wing respectively, and fold mechanism (torsional spring connection
Between the first pin and the second pin, the first pin is set in wing shaft, and the second pin is set to interconnecting piece.Torsional spring
Two ends be exposed to it is outer, when torsional spring is accepted excessive, rigidity is excessive, compression number is excessive when, spring is easy from the first pin
Or second pin fall off, cause wing can not normal rotation.Spring is also without any blocking or protective device, the mistake of wing rotation
Cheng Zhong, spring are easy to produce inclination, and wing is caused to rotate not in place or wing angle offset.Spring is directly set in shaft,
This pulls axes of rotation skew when will result directly in spring torsion, and wing, which can not be stablized, to be strutted.Wing rotation is unstable will to reduce nobody
Safety in machine use process not only reduces the service life of unmanned plane, and being also easy to, which causes wing to fall off, brings peace to personnel
It is complete to threaten.Wing strut process it is unstable in the case where, bolt may deviate from limiting slot, cause wing that can not be accurately positioned.
Utility model content
The utility model overcomes the deficiencies in the prior art, and providing a kind of wing being capable of stable rotation and can effective position
Collapsible unmanned plane, unreliable, stability and safety are low and can not accurately determine when solving the wing rotation of existing unmanned plane
The problem of position.
In order to solve the above technical problems, the utility model uses following technical scheme:
A kind of wing stable rotation and the collapsible unmanned plane positioned, including bulkhead are provided with several mounting bases on bulkhead,
It is provided with mounting hole in the middle part of mounting base, is arranged with wing shaft, one end of wing shaft is connected with wing；It is also set in mounting base
It is equipped with bulkhead annular groove, bulkhead annular groove and mounting hole are concentric, and wing annular groove is provided on wing, is arranged in bulkhead annular groove
There is torsional spring, the other end of torsional spring is sheathed in wing annular groove, and one end of torsional spring engages with bulkhead, the other end and wing of torsional spring
Engaging；It is provided with wing block on wing, the bulkhead block for stopping wing block when wing is unfolded is provided on bulkhead,
There is also torsion for torsional spring when wing unfolded state.
As a preferred embodiment of the present invention, L-type slot, the L-type slot on bulkhead are provided on the bulkhead and wing
It is connected to bulkhead annular groove, the L-type slot on wing is connected to wing annular groove；The both ends of torsional spring are bent into grab, close to cabin
The grab of wall one end snap-fits into the L-type slot on bulkhead, and the grab close to wing one end snap-fits into the L-type slot on wing.
As a preferred embodiment of the present invention, there are two bearing, wings for installation between the wing shaft and mounting hole
Spacer is arranged in shaft, spacer is located between two bearings.
As a preferred embodiment of the present invention, the middle part of the wing shaft is hollow structure.

Then torsional spring is isolated from each other with wing shaft, wing shaft energy band motivation wing smooth rotation, is avoided torsion spring set and is turned set on wing
Torsional spring drives the case where wing shaft offset when on axis, into the stability correspondinglyd increase when wing rotation is verted.
When wing expands in place under the action of torsional spring, bulkhead block stops wing block, avoid wing after
Continuous torsion.There is also torsion for torsional spring when due to wing unfolded state, then there are also the trend close to the rotation of bulkhead block, wings for wing
Block is pressed on bulkhead block, and wing is avoided to turn round, so that wing obtains reliable location.Due to wing energy smooth rotation, then
When wing expands in place, bulkhead block is always positioned in the movement routine of wing block, further ensures bulkhead block to machine
The reliable blocking of wing block.
2, the grab at torsional spring both ends is engaged in L-type slot, then one end of torsional spring is fixed relative to bulkhead, the other end of torsional spring
It is fixed relative to wing, then wing can be rotated relative to bulkhead in torsional spring twist process, thus wing expansion or gathering.Grab quilt
It is limited in without deviating from bulkhead or wing in L-type slot, guarantees wing energy accurate rotational, after avoiding torsional spring abjection bulkhead or wing
The case where wing can not rotate in place.
3, bearing can effectively reduce frictional force when wing rotates, and further increase the stability in wing rotation process,
Reduce the case where wing generates inclination or shakes.Spacer can separate two bearings, avoid the roller phase mutual friction of two bearings
The case where.
4, wing spindle central is hollow structure, can play loss of weight.
5, end cap and hold-doun nut can limit the axial movement of wing shaft, guarantee that wing shaft is connected relative to mounting base
Reliably.The nut segment of wing shaft is sheathed in the hexagonal hole of wing, then wing and wing shaft will not generate loosening.
