[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The present application embodiment discloses a wind-breaking structure for the nose of a drone, referring to Figure 1 and Figure 2 , including a nose body 2, the nose body 2 is in the shape of a bullet, wherein horizontal main fins 4 are radially arranged on both sides of the nose body 2, the axis of the nose body 2 is located on the horizontal plane where the two horizontal main fins 4 are located, and the horizontal main fins 4 are symmetrically distributed on both sides of the nose. The horizontal main fins 4 symmetrical on both sides are combined with the nose in the shape of a bullet, thereby improving the wind-breaking ability of the nose and reducing wind resistance, while also improving the overall stability of the drone.

[0031] In this embodiment, aileron pieces 5 are vertically fixed on the upper and lower sides of each group of horizontal main wing pieces 4. The aileron pieces 5 are parallel to the axial direction of the nose body 2, and the aileron pieces 5 are close to the nose body 2, which is beneficial to maintaining the heading balance and stability of the drone during flight.

[0032] To facilitate on-site assembly, replacement and maintenance of the drone, in the embodiment of the present application, the fuselage body 1 and the head body 2 in the drone are assembled in a detachable connection manner. Specifically, the connecting end of the head body 2 is fixed with an annular protrusion 6, and the outer peripheral surface of the annular protrusion 6 is provided with an external thread. The annular protrusion 6 is used for threaded connection with the drone body, thereby achieving the purpose of detachable head body 2 and fuselage of the drone, which is beneficial to improve the connection stability between the fuselage body 1 and the head body 2 of the drone.

[0033] In order to improve the connection stability between the drone fuselage body 1 and the nose body 2, an anti-loosening washer 3 is sleeved on the outside of the annular protrusion 6. The anti-loosening washer 3 is clamped between the nose body and the fuselage, which is beneficial to reduce the loosening during the flight of the drone.

[0034] In order to reduce the overall volume of the bomb-carrying UAV, a warhead chamber 7 is provided inside the nose. The warhead chamber 7 is opened at one end close to the annular protrusion 6. The warhead chamber 7 is used to accommodate the bomb warhead, provide a storage space for the bomb warhead, and store the bomb, which is beneficial to improving the structural compactness of the bomb-carrying UAV. In this embodiment, a bomb body chamber is provided in the fuselage body 1. After the fuselage body 1 and the nose body 2 are assembled, the warhead chamber 7 and the bomb body chamber form a complete chamber to accommodate the bomb. Accommodating the bomb inside the UAV can minimize wind resistance, which is beneficial to improving the flight stability of the UAV.

[0035] The implementation principle of the wind-breaking structure of the drone nose in the embodiment of the present application is as follows:

[0036] When installing the bomb, the nose body 2 is removed from the UAV fuselage body 1, and then the bomb is loaded into the bomb body cavity of the fuselage body 1, and then the anti-loosening washer 3 is mounted on the outer periphery of the annular protrusion 6, and then the nose body 2 is threadedly connected with the fuselage body 1, thereby completing the assembly of the bomb-carrying UAV.

[0037] When the UAV is flying, the symmetrical horizontal main wing pieces 4 cooperate with the warhead-shaped nose, and under the action of the vertical aileron pieces 5, the wind-breaking ability of the nose is improved, the wind resistance is reduced, and the overall stability of the UAV is improved.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
