detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Fig. 1-3, the present invention provides a kind of technical solution: a kind of buffer structure for unmanned aerial vehicle landing, comprises fuselage 1 and cushioning leg 14, and the lower end edge of fuselage 1 is provided with fuselage leg 2, and machine The lower end of the body support leg 2 is equipped with a support leg cushioning device 3, and the fuselage support leg 2 and the wrapping groove 6 are embedded installation structures, which are convenient for the support leg cushioning device 3 while protecting the fuselage support leg 2. The installation and disassembly of the fuselage 1 is fixed with a fuselage base 4 at the center of the lower end of the fuselage 1, and the fuselage cushioning device 5 is arranged at the lower end of the fuselage base 4, and the inner upper end of the outrigger cushioning device 3 is provided with a wrapping groove 6, and the support The inner lower end of the leg cushioning device 3 is respectively equipped with a cushioning block 7 and a first spring 8 from top to bottom, the lower end of the first spring 8 is fixed with a base 9, and the lower end of the base 9 is provided with a wear-resistant pad 10, the fuselage A foam layer 11 is installed on the upper surface of the cushioning device 5, and connectors 12 are fixed on both sides of the fuselage cushioning device 5.
