Embodiment Construction

[0029] Such as figure 1 As shown in the drone with the embodiment of the present invention, the drone 8 includes a landing buffer system 1, the landing buffer system 1 is arranged below the drone 8, and the landing buffer airbag of the present invention is folded and arranged in the landing buffer system 1.

[0030] Such as figure 2 , Figure 4 As shown, the embodiment of the landing buffer airbag of the present invention includes a skeleton airbag and an outer capsule body 5, the skeleton airbag communicates with the air source 7 in the landing buffer system 1, and the upper end of the skeleton airbag is connected to the bottom of the drone.

[0031] The skeleton airbag comprises an upper annular airbag 2, a lower annular airbag 3 and a strut airbag 4. The strut airbag 4 is arranged between the upper annular airbag 2 and the lower annular airbag 3, and the upper annular airbag (2) is connected to the bottom of the drone. connect. The upper annular airbag 2, the lower annu...

Abstract

The invention relates to a landing cushion gasbag, which comprises a frame type gasbag, wherein the frame type gasbag is communicated with gas resource in a landing cushion system (1), and the upper end of the frame type gasbag is communicated with the bottom of an unmanned aerial vehicle. The landing cushion gasbag has the advantages that: the frame type gasbag is communicated with the gas resource in the landing cushion system, and the gas resources such as a mini-type high-pressure gas bottle or a gas generating device, and the like, are used for aerating the frame type gasbag when the unmanned aerial vehicle is landed with a parachute, so that the gasbag can provide cushion to the unmanned aerial vehicle when loading after the frame type gasbag is aerated. As the cubage of the frame type gasbag is far less than the existing gasbag, the package of the gasbag is less, the weight is light, and the gasbag can be aerated without atmosphere source.

Description

technical field [0001] The invention relates to an unmanned aircraft, in particular to a landing buffer system for a parachute landing UAV, especially a landing buffer airbag in the landing buffer system. Background technique [0002] The UAV recovery system is generally composed of a parachute system and a landing buffer system. The parachute system slows down the UAV and makes it land at a certain speed, while the landing buffer system absorbs the impact energy of landing to further reduce the impact of the UAV. Landing speed to ensure safe landing of the UAV. The landing cushion airbag is a cushioning method with relatively simple structure, low cost and wide application range among many cushioning systems. [0003] Landing buffer airbags are generally made of fabric-coated materials, and are pre-inflated and deployed by their own air source. When landing, the gas in the airbag is compressed by the impact energy of landing, and the gas is released after blasting through ...
