When the protective housing shell 11 reciprocates circumferentially on the flight support plate 1 through the suspension shaft 6, it will drive the suspension support shaft 9 to slide reciprocatingly in the first rotating through hole and the second rotating through hole 13 in the circumferential direction, and then drive the slider 10 to slide reciprocatingly in the suspension connection slide groove 12 in the circumferential direction.

[0043] The automatic loading and unloading parts include horizontal loading and unloading parts and auxiliary loading and unloading parts, wherein the horizontal loading and unloading parts are arranged on the cargo accommodating parts and the auxiliary loading and unloading parts are arranged on the unmanned aerial parts. The horizontal loading and unloading parts include loading and unloading transmission parts and loading and unloading power parts, wherein the loading and unloading transmission parts and the loading and unloading power parts are both arranged on the accommodating shell.

[0044] The loading and unloading transmission member includes a loading and unloading support guide groove 14, a loading and unloading transmission plate 15, a loading and unloading transmission block 16 and a lower baffle 17. The loading and unloading support guide groove 14 is in a C-shaped tubular shape. The loading and unloading support guide groove 14 is fixedly arranged on the barrel mouth wall of the protective accommodating shell 11, and the axis of the loading and unloading support guide groove 14 is perpendicularly intersected with the axis of the protective accommodating shell 11. The loading and unloading transmission plate 15 is in the shape of a long thick plate. The loading and unloading transmission plate 15 is slidably embedded in the loading and unloading support guide groove 14, so that the loading and unloading transmission plate 15 slides back and forth axially in the loading and unloading support guide groove 14. The loading and unloading transmission block 16 is in the shape of a rectangular plate. The upper side of the loading and unloading transmission block 16 passes through the notch of the loading and unloading support guide groove 14 and is fixedly arranged on the bottom surface of the loading and unloading transmission plate 15. The lower baffle 17 is in the shape of a right-angled sector, and the radius of the lower baffle 17 is the same as the radius of the protective housing shell 11, and the circumferential angle of the lower baffle 17 is 90 degrees. The lower baffle 17 is horizontally fixed on the lower side of the loading and unloading transmission block 16, and the center of the circle of the lower baffle 17 can move radially with the loading and unloading transmission plate 15 and coincide with the axis of the protective housing shell 11. Furthermore, one end of the connection between the lower baffle 17, the loading and unloading transmission block 16 and the loading and unloading transmission plate 15 is treated with a slope 18. When the loading and unloading transmission plate 15 drives the lower baffle 17 to move toward the axis of the protective housing shell 11, the lower baffle 17 can be inserted between the package and the ground, thereby loading the package into the protective housing shell 11.

[0045] The loading and unloading power part includes a second motor 19 and a gear 20. The second motor 19 is fixedly arranged on the inner wall of the protective housing 11. The shaft of the second motor 19 rotates and penetrates into the loading and unloading support guide groove 14. The gear 20 is fixedly sleeved on the shaft of the second motor 19, and the gear 20 is located in a transmission groove 21 on the top surface of the loading and unloading transmission plate 15. A groove wall on one side of the transmission groove 21 is provided with gear teeth, and the gear teeth are meshed with the gear 20. When the second motor 19 drives the gear 20 to rotate, the loading and unloading transmission plate 15 is driven by the gear teeth to slide along the radial line in the loading and unloading support guide groove 14, thereby loading the package into the protective housing 11.

[0046] There are four sets of the horizontal loading and unloading parts, which are evenly distributed around the protective housing shell 11. It should be noted that when the package is placed at a predetermined position, the unmanned flying part will drive the cargo housing part to descend, and then the protective housing shell 11 will be put on the package from top to bottom, and then the package will be loaded into the protective housing shell 11 through the horizontal loading and unloading parts.

[0047] The auxiliary loading and unloading part includes a third motor 22, a worm 23 and a worm gear 24. The third motor 22 is fixedly arranged on the flight support plate 1, the worm 23 is arranged on the rotating shaft of the third motor 22, the worm gear 24 is fixedly sleeved on one end of the suspension rotating shaft 6, and the worm gear 24 is meshed with the worm 23. When the horizontal loading and unloading part moves along the radial line for loading and unloading, the auxiliary loading and unloading part drives the protective housing shell 11 to reciprocate and rotate rapidly in the circumferential direction by a certain angle to reduce the friction between the horizontal loading and unloading part and the package and the ground, so as to improve the loading and unloading efficiency of the package.

[0048] As described above, the low-altitude UAV with improved anti-interference capability of the present invention is provided with a protective housing shell and an automatic loading and unloading component, and the automatic loading and unloading component can automatically load the package into the protective housing shell; since the side wall of the protective housing shell is a streamlined body in the shape of an arc, when the low-altitude unstable air disturbance blows through the protective housing shell, it will pass over the side wall of the protective housing shell, thereby reducing the unstable air from blowing directly on the package and causing unstable shaking of the UAV, thereby improving the anti-interference capability and flight flexibility of the UAV during low-altitude flight.

[0049] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
