[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Combine the following Figures 1 to 4 The wing provided in the embodiment of the present invention is described.

[0035] Specifically, the wing is used to connect to the top or bottom of the fuselage 3 of the aircraft. Figure 1 What is shown is a schematic diagram of a wing connected to the top of a fuselage 3. The wing includes a wing body 1 and a connection seat 2.

[0036] The length direction of the wing body 1 extends in the lateral direction of the fuselage 3, and the two ends of the wing body 1 in the length direction are respectively arranged on both sides of the fuselage 3. Specifically, one end of the wing body 1 in the length direction is arranged on the left side of the fuselage 3, and the other end of the wing body 1 in the length direction is arranged on the right side of the fuselage 3.

[0037] The connection base 2 is connected to the wing body 1. Optionally, the connection base 2 is welded to the wing body 1. The connection base 2 is provided with a connection hole 201 for the threaded connector 5 to pass through, and the connection base 2 is detachably connected to the fuselage 3 through the threaded connector 5 passing through the connection hole 201. For example, the fuselage 3 is provided with a connection plate 4, and the threaded connector 5 passes through the connection hole 201 of the connection base 2 and the connection plate 4 and cooperates with the nut thread, so as to connect the connection base 2 to the fuselage 3.

[0038] The wing provided in the embodiment of the utility model extends in the lateral direction of the fuselage 3 through the length direction of the wing body 1, and the two ends of the wing body 1 in the length direction are respectively arranged on both sides of the fuselage 3, that is, the wing body 1 is equivalent to the left wing and the right wing of the aircraft in the prior art being combined into one, thereby reducing the number of wings relative to the aircraft in the prior art. In addition, by arranging a connection seat 2 on the wing body 1, and the connection seat 2 is provided with a connection hole 201 for the threaded connector 5 to pass through, the wing body 1 can be detachably connected to the fuselage 3 through the threaded connector 5 passing through the connection hole 201, so as to facilitate the disassembly of the wing body 1.

[0039] In summary, in the wing provided in the embodiment of the utility model, the connection seat 2 of the wing body 1 is detachably connected to the fuselage 3 through the threaded connector 5, so that the wing can be removed from the fuselage 3. By making the length direction of the wing body 1 extend along the lateral direction of the fuselage 3, and the two ends of the wing body 1 in the length direction are respectively arranged on both sides of the fuselage 3, the number of wings on the aircraft can be reduced, so when the wings are disassembled and assembled, the disassembly and assembly efficiency of the wings of the aircraft is higher.

[0040] In addition, since the number of wings of the aircraft is reduced, the number of threaded connectors 5 required for the wings provided by the utility model is less than the number of threaded connectors 5 required for the left and right wings in the prior art. This can reduce the time spent on disassembling and assembling the threaded connectors 5 and reduce the cost of the aircraft.

[0041] refer to Figure 1-Figure 4 As shown, in some embodiments provided by the present invention, at least two groups of connection seats 2 arranged along the length direction of the wing body 1 are provided on the wing body 1, and each group of connection seats 2 includes at least two connection seats 2 arranged along the width direction of the wing body 1. Such an arrangement can improve the connection strength between the wing and the fuselage 3.

[0042] For example, Figure 1-Figure 4 As shown in the figure, two groups of connection seats 2 are arranged along the length direction of the wing body 1, and the two groups of connection seats 2 are close to the two sides of the fuselage, so that the airflow can flow between the two groups of connection seats 2 during the flight of the aircraft, reducing the obstruction of the connection seats 2 to the airflow and improving the aerodynamic performance of the aircraft. Each group of connection seats 2 includes two connection seats 2 arranged along the width direction of the wing body 1, so as to ensure the connection strength and stability between the wing and the fuselage 3.

[0043] Furthermore, each connecting seat 2 is provided with a connecting hole 201, so that when disassembling the wing, only four threaded connectors 5 need to be disassembled. Compared with the prior art in which the left and right wings of the aircraft require at least four connectors to be fixed, this can greatly reduce the difficulty of disassembling the wing and improve the efficiency of disassembling the wing.

[0044] refer to Figure 3 and Figure 4 As shown, in some embodiments provided by the utility model, the connection base 2 includes a pair of connection ears 202. There is a spacing between the pair of connection ears 202, so that the connection plate 4 on the body 3 can be inserted, and the connection hole 201 on the connection base 2 passes through the pair of connection ears 202. During use, the connection plate 4 on the body 3 is inserted between the pair of connection ears 202, and the threaded connector 5 passes through the connection ears 202 and the connection plate 4 and is connected to the nut to connect the connection plate 4 to the connection ears 202.

[0045] In this way, a pair of connecting ears 202 are connected to the connecting plate 4 at the same time, so that the pair of connecting ears 202 can share the force with each other, reduce the force on a single connecting ear 202, reduce the probability of damage, and extend the service life of the connecting ear 202.

[0046] like Figure 3 As shown, in some embodiments provided by the utility model, the thickness direction of the connecting ear 202 is arranged along the length direction of the wing body 1. The connecting hole 201 penetrates the connecting ear 202 along the thickness direction of the connecting ear 202, that is, the axial direction of the connecting hole 201 extends along the length direction of the wing body 1. Specifically, the connecting ear 202 is arranged as a plate-shaped structure, that is, the plate thickness direction of the plate-shaped structure is arranged along the length direction of the wing body 1. Since the thickness direction dimension of the connecting ear 202 is smaller than the dimension of the plate surface of the connecting ear 202, the thickness direction of the connecting ear 202 has less obstruction to the airflow during the flight of the aircraft, so that the aerodynamic performance of the aircraft is better. The connecting hole 201 is arranged on the plate surface of the connecting ear 202, so that the processing difficulty of the connecting hole 201 is smaller. In addition, after the connecting plate 4 of the fuselage 3 is docked with the connecting ear 202, the thickness direction of the connecting plate 4 can also be arranged along the length direction of the wing body 1, thereby reducing the obstruction of the connecting plate 4 to the airflow.

[0047] In some embodiments provided by the present invention, the wing body 1 includes a left wing portion 101 and a right wing portion 102 .

[0048] The left wing portion 101 and the right wing portion 102 are connected, and the left wing portion 101 and the right wing portion 102 extend toward both sides of the fuselage 3, respectively. Specifically, the left wing portion 101 extends toward the left side of the fuselage 3, and the right wing portion 102 extends toward the right side of the fuselage 3. There is a non-180-degree angle between the left wing portion 101 and the right wing portion 102, and the left wing portion 101 and the right wing portion 102 are both provided with a connecting seat 2, so that the left wing portion 101 and the right wing portion 102 can be connected to the fuselage 3 through the corresponding connecting seat 2.

[0049] Specifically, for example, refer to Figure 1 As shown, the ends of the left wing part 101 and the right wing part 102 that are away from each other are both tilted upward, so that the left wing part 101 and the right wing part 102 both form an upward dihedral, thereby increasing the lateral stability of the aircraft. Alternatively, the ends of the left wing part 101 and the right wing part 102 that are away from each other are both tilted downward, so that the left wing part 101 and the right wing part 102 both form an downward dihedral, achieving the purpose of reducing lateral stability and improving maneuverability.

[0050] In some embodiments provided by the utility model, the left wing part 101 includes a left wing frame and a left wing skin 101d covered on the outside of the left wing frame. The right wing part 102 includes a right wing frame and a right wing skin 102d covered on the outside of the right wing frame. The left wing frame and the right wing frame are connected, for example, the left wing frame and the right wing frame can be welded or connected by threaded fasteners or anchors. The left wing skin 101d and the right wing skin 102d are connected, for example, the left wing skin 101d and the right wing skin 102d can be adhesively connected. The connecting seat 2 is connected to the left wing frame or the right wing frame.

[0051] With such arrangement, the left wing part 101 and the right wing part 102 can be assembled and connected after being processed separately, thereby reducing the processing difficulty of the wing body 1.

[0052] In some embodiments provided by the present invention, the left wing skeleton includes a left wing front beam 101a, a left wing rear beam 101b and a left wing reinforcement rib 101c, and the left wing reinforcement rib 101c connects the left wing front beam 101a and the left wing rear beam 101b. For example, the left wing reinforcement rib 101c connects the left wing front beam 101a and the left wing rear beam 101b by welding or riveting.

[0053] The right wing frame includes a right wing front beam 102a, a right wing rear beam 102b and a right wing reinforcement rib 102c, and the right wing reinforcement rib 102c connects the right wing front beam 102a and the right wing rear beam 102b. For example, the right wing reinforcement rib 102c connects the right wing front beam 102a and the right wing rear beam 102b by welding or riveting.

[0054] The left wing front beam 101a is connected to the right wing front beam 102a, and the left wing rear beam 101b is connected to the right wing rear beam 102b. For example, the left wing front beam 101a and the right wing front beam 102a can be welded or connected by threaded fasteners or anchors. The left wing rear beam 101b and the right wing rear beam 102b can be welded or connected by threaded fasteners or anchors. The connecting seat 2 can be connected to the left wing reinforcement rib 101c or the right wing reinforcement rib 102c.

[0055] In some embodiments provided by the present invention, the left wing skin 101d and the right wing skin 102d each include two skin components spliced ​​up and down, for example, the two skin components can be bonded together. In this way, the two skin components can be processed separately and then spliced ​​onto the left wing frame or the right wing frame, thereby reducing the processing difficulty of the left wing skin 101d and the right wing skin 102d.

[0056] An embodiment of the utility model also provides an aircraft.

[0057] In particular, the aircraft comprises a fuselage 3 and wings as described above.

[0058] It should be noted that an airplane includes wings and also includes all the above-mentioned advantages of wings, which will not be elaborated here.
