Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicle accessories, in particular to an impact-resistant carbon fiber shell of a unmanned aerial vehicle. Background Art

[0002] When performing flight missions, drones are prone to encounter adverse terrain or airflow, which may cause the drones to bump and collide, and the impact may cause a certain degree of damage to the drone's fuselage and wings. At present, in order to enhance the impact resistance of drones, most use carbon fiber fuselage shells, taking advantage of the high strength, light weight, low creep, and strong corrosion resistance of carbon fiber, so that the impact resistance of drones is enhanced, the use safety is high, and the service life is long, making them more suitable for aerial photography, detection, police use, plant protection and disaster relief and other fields. However, when encountering adverse airflow, the wings are more susceptible to impact, but the existing technology lacks means to protect the wings. Utility Model Content

[0003] The purpose of this application is to provide an impact-resistant carbon fiber shell for a drone, aiming to solve the problems existing in the prior art.

[0004] The embodiment of the present application provides an impact-resistant carbon fiber shell for a drone, including a cylindrical shell made of carbon fiber. The shell is installed on the outside of the drone wing, and a plurality of inclined air inlets are evenly arranged on the circumferential surface of the shell. The air flow direction generated by the inclined air inlets in the shell is consistent with the rotation direction of the drone wing; an upper cover is installed on the upper end of the shell, and a lower cover is installed on the lower end of the shell. Arc-shaped raised buffer belts are provided on the outer circumferential surfaces of the upper cover and the lower cover, and the interior of the buffer belt is hollow.

[0005] Furthermore, the inner diameter of the upper cover is smaller than the inner diameter of the shell so that the upper cover forms a convex body extending inwards.

[0006] Furthermore, a connecting rod extending inwardly is fixedly connected to the inner circumferential surface of the convex body, and the connecting rod is fixedly connected to the top plate at the center of the circle.

[0007] Furthermore, a connecting rod extending inward is fixedly connected to the inner circumference of the lower cover, and the connecting rod is fixedly connected to the bottom plate at the center of the circle, and the bottom plate and the top plate are located on the axis.

[0008] Furthermore, the width of the protrusion is smaller than the thickness of the shell.

[0009] Furthermore, the upper cover, the lower cover and the buffer belt are all made of carbon fiber.

[0010] The beneficial effects of the utility model are as follows: the utility model surrounds and protects the wings through the shell to prevent the wings from being impacted and collided. The inclined air inlet is provided on the circumference of the shell to generate vortex airflow in the shell in the same direction as the rotation direction of the wing, which drives the wing to rotate and reduces kinetic energy loss. The buffer belt arranged on the outer periphery of the shell is a hollow carbon fiber structure, which has the function of collision deformation and absorption of impact force.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0017] like Figure 1-Figure 3 The impact-resistant carbon fiber shell of a drone shown in the figure comprises a cylindrical shell 1, the shell 1 is made of carbon fiber and has the advantages of high strength and light weight. The shell 1 is installed on the outside of the drone wing to provide impact protection for the drone wing.

[0018] like Figure 2 As shown, the circumference of the shell 1 is evenly provided with a plurality of inclined air inlets 2, which penetrate the shell 1. The cross-sections of the air inlets 2 on the outer and inner circumferences of the shell 1 are rectangular, and there is a misalignment between the two circumferences so that the entire air inlet 2 flow channel is inclined. When the wing rotates, the air blows from the top of the wing to the bottom, and the air is sucked into the shell 1 from the air inlet 2. The inclined air inlet 2 generates a vortex-shaped airflow in the shell 1. The flow direction of the airflow is consistent with the rotation direction of the drone wing. When the airflow passes through the wing from top to bottom, it can assist the wing rotation and reduce the power consumption of the wing.

[0019] like Figure 3As shown, an upper cover 3 is installed at the upper end of the shell 1, and a lower cover 4 is installed at the lower end of the shell 1. A buffer belt 5 with an arc-shaped protrusion is provided on the outer peripheral surface of the upper cover 3 and the lower cover 4, and the inside of the buffer belt 5 is hollow. The upper cover 3, the lower cover 4 and the buffer belt 5 are all made of carbon fiber. The hollow buffer belt 5 is deformed by impact to absorb impact energy, thereby protecting and buffering the wing.

[0020] The inner diameter of the upper cover 3 is smaller than the inner diameter of the shell 1, so that the upper cover 3 forms a convex body 6 extending inward, and the width of the convex body 6 is smaller than the thickness of the shell 1. A connecting rod 7 extending inward is fixedly connected to the inner circumferential surface of the convex body 6, and the number of the connecting rods 7 is multiple, and the multiple connecting rods 7 are fixedly connected to the top plate 8 at the center of the circle.

[0021] The inner circumference of the lower cover 4 is fixedly connected with a connecting rod 7 extending inwardly. The connecting rod 7 is fixedly connected to the bottom plate 9 at the center of the circle. The bottom plate 9 and the top plate 8 are located on the axis.

[0022] Most UAVs have four wings. The utility model provides a shell 1 outside each wing. The wings of the UAV are located in the shell 1. The shaft that drives the wings to rotate passes through the bottom plate 9 and is connected to the external transmission mechanism. The bottom plate 9 is provided with an axis hole 10. The shaft is rotatably connected to the axis hole 10, and the rotating upper end is relatively rotatably connected to the top plate 8, so that the shell 1 is installed outside the wing.

[0023] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
