Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
Such as Fig. 1, shown in 2,3, a kind of folding unmanned plane wing, including inner end wing 1 and outer end wing 2, it is described in The side of the terminal wing is fixedly connected with fuselage, and the other side is flexibly connected outer end wing, the top airfoil of inner end wing and outer end wing It is connected by hinge 3, the lower end surface of the inner end wing and outer end wing is equipped at least two groups locking mechanism, the locking mechanism Including the first screw 4, connecting plate 5, the second screw 6, third screw 7, the connecting plate is carbon plate, and first screw 4 is fixed In the lower aerofoil of outer end wing 2, second screw 6 and third screw 7 are fixedly arranged on the lower aerofoil of inner end wing 1, the connection First through hole 9, the second through-hole 10 and concave card slot 8,9 company of being respectively arranged on of the concave card slot 8 and first through hole are offered on plate The both ends of fishplate bar 5, the second through-hole 10 are set between first through hole and concave card slot, and the first through hole 9 of the connecting plate is sheathed on On first screw 4, second through-hole 10 is socketed at the second screw 6 when opening for outer end wing, and concave card slot 8 is for outer The terminal wing is connected on third screw 7 when opening.
Further, first screw 4, the second screw 6, third screw 7 are located in a straight line, and with inner end wing It is parallel;The distance between second screw and third screw distance between the second through-hole and concave card slot are consistent, the first screw The distance between second screw and the distance between first through hole and the second through-hole are consistent;First screw, the second screw, third Screw is soket head cap screw, and the diameter of the first screw, the second screw, third screw is less than first through hole and the second through-hole Diameter;The lower aerofoil of the outer end wing is equipped with the 4th screw 9.By the setting of the 4th screw, so that after the wing-folding of outer end Second through-hole of connecting plate is socketed on the 4th screw, with fixed connecting plate, saves space.
One end of the hinge is fixedly arranged on the wing of inner end, and the other end is fixedly arranged on the wing of outer end, the iron axis among hinge It is parallel that the gap generated is contacted with inner end wing and outer end wing, and is located among gap.
In use, inner end wing is connected with fuselage, the wherein half of hinge is fixed on outer end wing, the other end with screw It is fixed on inner end wing, so that outer segment wing is rotated 0 ° to 180 ° relative to inner end wing, when wing needs to be unfolded, will pacify It is consistent with wing extension direction that connection carbon plate on the wing of outer end is threaded to three circular hole orientations on carbon plate, when under wing Can let go when putting angle greater than 45 ° allows it to rotate freely whereabouts by gravitional force, when wing substantially is unfolded to complete, connects carbon Plate will contact the soket head cap screw on the wing of inner end, and since connection carbon plate has certain elasticity, carbon plate can be bent outwardly, at this time Outer end wing is still in the angle for expanding itself and home position, and when angle is extended to 180 °, the outer end machine wing is expanded to and inner end When wing is parallel, connect carbon plate on corresponding hole will entangle with soket head cap screw mounted on the wing of inner end, make to connect Carbon plate is bonded two sections of wings completely, has just reached the function of locking after wing expansion at this time.
The foldable unmanned plane wing wing structure of the present invention is simple, and Foldable convenient coat not only realizes the folding of unmanned plane wing, And convenient locked simplicity is opened, guarantee the stability of wing in flight course.
