[0022] The following description is merely exemplary in nature and is not intended to limit the present application, application or use. Furthermore, there is no intention to be limited by any express or implied theory presented in the preceding technical field, background technology and utility model content or the following detailed description. It should be understood that throughout the drawings, corresponding reference numerals identify similar or corresponding parts or features.

[0023] The present application will now be further elaborated. In the following paragraphs, different aspects of the present application are defined in more detail. Unless clearly indicated to the contrary, each aspect so defined can be combined with any other (multiple) aspects. Especially, any feature indicated as preferred or advantageous can be combined with any other (multiple) features indicated as preferred or advantageous.

[0024] The present application provides a new wing, which connects the wing body and the control surface through the clamping of the ball joint and the curved groove. Figure 1 , Attachment Figure 2 and attached Figure 3 , schematically shows a wing 100 according to the principle of the present application, including a wing body 110 and a control surface 120. The wing body 110 is provided with a ball joint 111. It should be noted that the ball joint 111 in the present application can be spherical or substantially spherical, for example, it can be spherical or ellipsoidal, or substantially spherical or substantially ellipsoidal. The control surface 120 is provided with a curved groove 121. The curved groove 121 is a through groove that runs through the thickness of the control surface. Its wall and bottom are both curved surfaces that can be matched with the ball joint 111. The curved groove 121 intersects with the surface of the control surface 120 to form a notch 123, and the width b of the notch 123 is smaller than the width a of the ball joint 111, that is, smaller than the maximum dimension of the ball joint 111 along the length direction of the wing. It is easy for a person skilled in the art to understand that, since the size of the notch 123 is smaller than the width of the ball joint 111, the ball joint 111 can be stably engaged in the curved groove 121 without using additional accessories and is not easy to fall off. At the same time, the engagement between the ball joint 111 and the curved groove 121 can make the control surface 120 swing around the engagement point between the ball joint 111 and the curved groove 121 under the drive of the steering gear (not shown). The number of ball joints 111 and curved grooves 121 can be set according to the design specifications of the wing 100.

[0025] Alternatively, in the wing according to the principle of the present application, the ball joint can also be arranged on the rudder surface, and the curved groove can be arranged on the wing body. In this embodiment, except that the arrangement positions of the ball joint and the curved groove are different, other features are the same as the above-mentioned embodiment.

[0026] Refer to the attached Figure 2The ball joint 111 may be provided with a first mounting hole 112, and the side wall (side) of the curved groove 121 may be provided with a second mounting hole 122, wherein the first mounting hole 112 and the second mounting hole 122 are aligned and may be connected by a rod (not shown) such as a pin or a shaft, and the rudder surface 120 can swing around the rod, which enables the ball joint 111 and the curved groove 121 to be connected by the rod while being clamped, further enhancing the connection stability between the two. It is easy for those skilled in the art to understand that since the ball joint 111 and the curved groove 121 may be worn after the wing is used for a long time, the clamping of the two may become loose and there is a risk of falling off, and the ball joint 111 and the curved groove 121 are connected by the rod, so that the ball joint 111 and the curved groove 121 can be stably connected even if they are worn, and the normal rotation of the rudder surface 120 can be guaranteed.

[0027] Advantageously, the first mounting hole 112 may be a through hole, that is, the first mounting hole 112 passes through the ball joint 111. Advantageously, the second mounting hole 122 may also be a through hole, that is, the second mounting holes 122 of adjacent curved grooves 122 are connected, or the second mounting hole 122 passes through the end surface of the wing body or the control surface to form a through hole, see the attached Figure 3 Thus, the processing difficulty of the first mounting hole 112 and the second mounting hole 122 is reduced, and a plurality of ball joints 111 can be connected with a plurality of corresponding curved grooves 122 through a rod, simplifying the assembly process.

[0028] Refer to the attached Figure 2 Advantageously, the wing 100 according to the principles of the present application may further include a hemispherical joint 113 and a concave curved surface 124 disposed at the wing end surface. It is easy for a person skilled in the art to understand that the wing end surface may be composed of an end surface of the wing body 110 and an end surface of the rudder surface 120 connected together, the hemispherical joint 113 may be disposed at one or both end surfaces of the wing body 110, and the concave curved surface 124 may be disposed at the end surface of the rudder surface 120 (wherein, Figure 3The concave curved surface 124 is shown to be arranged at the two end surfaces of the rudder surface 120). The hemispherical joint 113 may be hemispherical, hemi-ellipsoidal, substantially hemispherical or substantially hemispherical, and the hemispherical joint 113 may be provided with a plane 115 flush with the wing end surface, so that the plane becomes a part of the wing end surface, ensuring that the wing end surface is flat. The concave curved surface 124 can be adapted to the hemispherical curved surface of the hemispherical joint 113 and does not affect the rotation of the rudder surface 120. The hemispherical joint 113 may be provided with a third mounting hole 114, and the concave curved surface 124 may be provided with a fourth mounting hole 125, wherein the third mounting hole 114 is aligned with the fourth mounting hole 125 so that the hemispherical joint 113 and the concave curved surface 124 are connected by a rod (not shown). The third mounting hole 114 may be a through hole that passes through the hemispherical joint 113, and the fourth mounting hole 125 may be a through hole that communicates with the second mounting hole 122 of the adjacent curved groove 121, so that the hemispherical joint 113, the concave curved surface 124, the spherical joint 111 and the curved groove 122 may be connected by a rod. The connection between the hemispherical joint 113 and the concave curved surface 124 enables the wing body 110 and the control surface 120 to be connected at their respective end faces, thereby increasing the connection strength between the two and also preventing the control surface 120 from being deformed during long-term use. Advantageously, the hemispherical joint 113 is also provided with planes that are flush with the upper and lower surfaces of the wing, respectively. Alternatively, the hemispherical joint may also be provided on the control surface, and the concave curved surface may be provided on the wing body.

[0029] Refer to the attached Figure 4 Advantageously, the spherical joint 111 is provided with planes 116 and 117 respectively flush with the upper and lower surfaces of the wing 100, and the hemispherical joint 113 is provided with planes 118 and 119 respectively flush with the upper and lower surfaces of the wing 100 to ensure smooth upper and lower surfaces of the wing.

[0030] Advantageously, the gap between the spherical joint 111 and the curved groove 121 and the gap between the hemispherical joint 113 and the concave curved surface 124 are between 0.02 mm and 0.8 mm, thereby ensuring a stable connection between the wing body 110 and the rudder surface 120. Technical personnel in this field can select a specific gap value within this range based on the requirements for the flexibility of the rudder surface 120.

[0031] Advantageously, the wing according to the principles of the present application can be made of polymer materials such as ASA plastic, or metal to ensure its strength and reduce manufacturing costs.

[0032] Advantageously, a wing according to the principles of the present application may be manufactured by additive manufacturing or die forming.

[0033] The present application also discloses an aircraft including a wing according to the principle of the present application. The aircraft may be an unmanned aircraft or a manned aircraft.

[0034] The wing and the aircraft including the same according to the principle of the present application, by providing a spherical joint and a curved groove, the wing body and the rudder surface are clamped together, which simplifies the processing process and reduces the cost. By providing a hemispherical joint and a concave curved surface, and using a rod to connect the spherical joint with the curved groove and the hemispherical joint with the concave curved surface, the connection stability between the wing body and the rudder surface is further strengthened, and deformation of the rudder surface is prevented.
