In this way, each lever group can form a rotatable connection with the wing element edge member on the wing element outer frame 400 by the hinged support, thereby realizing a linkage relationship between the airfoil control structure and the wing element outer frame 400.

In order to enable the first airfoil control unit 500 at the front of the wing element to still realize airfoil control capability under complex deformation of the first wing element edge member 2, the second wing element edge member 4, the seventh wing element edge member 12 and the eighth wing element edge member 14, and to transmit the relative movement between the first sliding ring 24 and the first sliding rod 25, as shown in FIG. 8, the first sliding ring connecting rod 23 is connected to the wing leading edge support rod connecting member 110 in a spherical hinge manner, and the first sliding rod 25 is connected to the wing middle support rod connecting member 210 in a fixed hinge manner.

As described above, the wing middle support rod connecting member 210 is connected to the wind trailing edge support rod connecting member 310 by the second airfoil control unit 600. As shown in FIG. 9, FIG. 9 shows a three-dimensional structure of the second airfoil control unit 600 and a connection relationship between same and the wing middle support rod connecting member 210 and the wing trailing edge support rod connecting member 310. The structure of the second airfoil control unit 600 is the same as that of the first airfoil control unit 500, and will not be elaborated more in the present disclosure.

Hereinafter, the movement control of the first airfoil control unit 500 located at the front of the wing element is described specifically:

- in the actual movement of the wing element structure, as long as the relative position between the wing leading edge support rod 100 and the wing middle support rod 200 changes, no matter swinging in a horizontal plane, or swinging in a vertical plane, or combined movement in the horizontal and vertical planes, the first sliding rod 25 will move relative to the first sliding ring 24. Further, due to the linkage relationship between the airfoil control structure and the wing element outer frame, due to the movement between the first sliding ring hinged support 39, the second sliding ring hinged support 40, the third sliding ring hinged support 41, and the fourth sliding ring hinged support 42 which are fixedly connected onto the first sliding ring 24 relative to the first sliding rod base hinged support 31, the second sliding rod base hinged support 32, the third sliding rod base hinged support 33, and the fourth sliding rod base hinged support 34 on the first sliding rod base 30 of the first sliding rod 25, the relative movement between the first sliding rod 25 and the first sliding ring 24 is transferred to the first rod 43, the second rod 44, the third rod 47, the fourth rod 48, the fifth rod 51, the sixth rod 52, the seventh rod 55, and the eighth rod 56; wherein a linkage relationship is generated between the first rod 43 and the second rod 44 by the second hinged support 46, a linkage relationship is generated between the third rod 47 and the fourth rod 48 by the fourth hinged support 50, a linkage relationship is generated between the fifth rod 51 and the sixth rod 52 by the sixth hinged support 54, and a linkage relationship is generated between the seventh rod 55 and the eighth rod 56 by the eighth hinged support 58. In addition, the relative movement between the first sliding ring 24 and the first sliding rod 25 is transferred to the first hinged support 45, the third hinged support 49, the fifth hinged support 53 and the seventh hinged support 57, and thus the relative movement between the first sliding ring 24 and the first sliding rod 25 is transferred to the first wing element edge member 2, the second wing element edge member 4, the seventh wing element edge member 12 and the eighth wing element edge member 14 which can achieve passive deformation. In this way, the first wing element edge member 2, the second wing element edge member 4, the seventh wing element edge member 12 and the eighth wing element edge member 14 which can achieve passive deformation can follow the relative movement between the first sliding ring 24 and the first sliding rod 25.

Further, along with the movement of the first wing element edge member 2, the second wing element edge member 4, the seventh wing element edge member 12 and the eighth wing element edge member 14, the first flexible connecting member 301 and the fourth flexible connecting member 1301 each forming a flexible connection between adjacent wing element edge members can also generate telescopic movement. One end of the first sliding cover plate 302 is fixedly connected to the first wing element edge member 2, and the other end thereof is a movement end and is slidably connected to the second wing element edge member 4, and along with the relative movement between the first wing element edge member 2 and the second wing element edge member 4, the movement end of the first sliding cover plate 302 is always closely attached to the second wing element edge member 4; and one end of the fourth sliding cover plate 1302 is fixed to the eighth wing element edge member 14, and the other end thereof is a movement end and is slidably connected to the seventh wing element edge member 12, and along with the relative movement between the eighth wing element edge member 14 and the seventh wing element edge member 12, the movement end of the fourth sliding cover plate 1302 is always closely attached to the seventh wing element edge member 12.

In addition, it should be noted that the wing leading edge support rod connecting member 110 can rotate around the wing leading edge support rod 100 or be fixed, and can serve as an active motor in a wing element structure requiring active change of angle of attack; and the wing leading edge support rod connecting member can serve as a passive rotation shaft sleeve in a wing element structure requiring passive change of angle of attack.

Of course, as for the motion control of the second airfoil control unit 600, reference is made to the first airfoil control unit 500, which will not be repeated herein.

By the wing element structure of the present embodiment, on the basis of the adjustment of the airfoil control units, the movement of the wing element structure can be realized, for example, by means of the movement of the wing structure or the change of relative positions; that is to say, various airfoil deformations can be realized, thereby realizing the basic action of plane airfoil transformation. FIGS. 10 and 11 are schematic diagrams of change of airfoil angle of attack. By means of the movement of the wing structure, cross sections of the wing element structures where the wing leading edge support rod 100, the wing middle support rod 200 and the wing trailing edge support rod 300 are located are in the same straight line and form a certain angle with respect to the horizontal plane, so as to achieve a pitch down action as shown in FIG. 10 and a pitch up action as shown in FIG. 11. Of course, as shown in FIGS. 12 and 13, the wing element structure in the embodiments of the present disclosure can also realize change in the shape of the wing element structure, i.e. telescoping deformation of the airfoil, for example, the two airfoil control units drive the wing element structure to be reduced; for example, by shortening the distances between the wing leading edge support rod 100, the wing middle support rod 200 and the wing trailing edge support rod 300, the relative movement between the first sliding ring connecting rod 23 and the first sliding rod 25 achieves an airfoil reduction action as shown in FIG. 12; or by prolonging the distances between the wing leading edge support rod 100, the wing middle support rod 200 and the wing trailing edge support rod 300, the two airfoil control units drive the wing element structure to be increased, thereby realizing an airfoil increase action as shown in FIG. 13. The embodiments of the present disclosure can also achieve a bending action of the airfoil plane of the wing element structure. FIGS. 14 and 15 are schematic diagrams of bending actions of an airfoil plane of the wing element structure, in which FIG. 14 shows a schematic diagram of upward bending of the wing element structure, and FIG. 15 shows a schematic diagram of downward bending of the wing element structure.

Of course, the airfoil change actions can realize complex actions of plane airfoil transformation by combination: such transformation uses permutation and combination of basic actions of the plane airfoil, belongs to a combined motion, and realizes complex transformation of the airfoil, which will not be elaborated more herein in the present disclosure. By the wing element structure of the present embodiment, multiple airfoil deformations can be achieved on the basis of the adjustment of the airfoil control units.
