[0022] The following description is merely exemplary in nature and is not intended to limit the present application, applications, or uses. Furthermore, no intention is to be bound by any expressed or implied theory presented in the preceding technical field, background, and summary 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 may be combined with any other (multiple) aspects. In particular, any feature indicated as preferred or advantageous may 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 spherical joint and the curved groove. Figure 1 , Attachment Figure 2 and attached Figure 3 , schematically illustrates a wing 100 according to the principles of the present application, comprising 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, in the present application, the ball joint 111 can be spherical or substantially spherical, for example, 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 extending through the thickness of the control surface, with its walls and bottom both being curved surfaces that can accommodate the ball joint 111. The curved groove 121 intersects with the surface of the control surface 120 to form a notch 123. The width b of the notch 123 is less than the width a of the ball joint 111, that is, less than the maximum dimension of the ball joint 111 along the length of the wing. Those skilled in the art will readily appreciate that, because 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 the use of additional accessories, preventing it from falling off. Furthermore, the engagement between the ball joint 111 and the curved groove 121 allows the control surface 120 to swing about the engagement point between the ball joint 111 and the curved groove 121 under the drive of a servo (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 a wing according to the principles of the present application, a ball joint may be provided on the rudder surface, and a curved groove may be provided on the wing body. In this embodiment, except for the different locations of the ball joint and the curved groove, other features are the same as those of the aforementioned 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. The first mounting hole 112 and the second mounting hole 122 are aligned and can be connected by a rod (not shown), such as a pin or a shaft. The rudder surface 120 can swing around the rod. This allows the ball joint 111 and the curved groove 121 to be connected simultaneously with the rod, further strengthening the stability of the connection between the two. Those skilled in the art will readily understand that after long-term use of the wing, the ball joint 111 and the curved groove 121 may wear, causing the connection between the two to loosen and even pose a risk of falling off. However, connecting the ball joint 111 and the curved groove 121 via a rod ensures that the ball joint 111 and the curved groove 121 remain stably connected even if they wear, and can ensure the normal rotation of the rudder surface 120.

[0027] Advantageously, the first mounting hole 112 can be a through hole, that is, the first mounting hole 112 passes through the ball joint 111. Advantageously, the second mounting hole 122 can 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 the multiple spherical joints 111 can be connected to the corresponding multiple curved grooves 122 through a rod, which simplifies 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 provided at the wing end surface. Those skilled in the art will readily appreciate that the wing end surface may be composed of the end surface of the wing body 110 and the end surface of the rudder surface 120 connected together, the hemispherical joint 113 may be provided at one or both end surfaces of the wing body 110, and the concave curved surface 124 may be provided at the end surface of the rudder surface 120 (wherein, Figure 3The concave curved surface 124 is shown disposed at both end surfaces of the control 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 flat surface 115 flush with the wing end surface, thereby making the flat surface a part of the wing end surface and ensuring a smooth wing end surface. The concave curved surface 124 can adapt to the hemispherical curved surface of the hemispherical joint 113 and does not affect the rotation of the control 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 and the fourth mounting hole 125 are aligned so that the hemispherical joint 113 and the concave curved surface 124 are connected via a rod (not shown). The third mounting hole 114 can be a through hole extending through the hemispherical joint 113, and the fourth mounting hole 125 can be a through hole connected to the second mounting hole 122 of the adjacent curved groove 121. This allows a single rod to connect the hemispherical joint 113, the concave curved surface 124, the spherical joint 111, and the curved groove 122. The connection between the hemispherical joint 113 and the concave curved surface 124 connects the wing body 110 and the control surface 120 at their respective end faces, increasing the strength of the connection and preventing deformation of the control surface 120 during long-term use. Advantageously, the hemispherical joint 113 is also provided with flat surfaces that are flush with the upper and lower surfaces of the wing, respectively. Alternatively, the hemispherical joint can be positioned on the control surface, while the concave curved surface can be positioned on the wing body.

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

[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 control surface 120. Those skilled in the art can select a specific gap value within this range based on the flexibility requirements of the control surface 120.

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

[0032] Advantageously, wings 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 comprising a wing according to the principles 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 principles of the present application clamp the wing body and the rudder surface together by providing a spherical joint and a curved groove, thereby simplifying the processing process and reducing costs. By providing a hemispherical joint and a concave curved surface, and using a rod to connect the spherical joint to the curved groove and the hemispherical joint to the concave curved surface, the connection stability between the wing body and the rudder surface is further strengthened, thereby preventing deformation of the rudder surface.
