Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 , figure 2 and image 3 As shown, the multi-stage airbag combined cushioning device of the present invention includes an inner airbag 1 and one or more outer airbags 2 nested in sequence, the outer airbag 2 is wrapped on the outside of the inner airbag 1, and the inner airbag 1 is degassable Inflatable airbags, the outer airbags 2 of each level are degassable non-inflatable airbags, the volume of the inner airbag 1 is smaller than that of the outer airbag 2 after inflation, and its volume ratio can be optimally designed according to the degree of instantaneous energy absorption in actual working conditions; the inner airbag 1 and the outer airbag 2 are made of fiber cloth with certain strength and good airtightness. There are no other mechanical accessories or filling materials, and only the low-cost and env...

Abstract

This multiple airbags bumping device comprises of an inner air bag and progressively embedded one or more outside airbags around the inner airbag that has several unidirection venting hole and several others of the outside airbags with the overall occupant area of the unidirection venting holes of the inner airbag bigger than that of all the outside airbags. It is simple in structure, convenient in operation, low of cost, and efficient in solving the low safety issue of the single airbag and the direct landing of large scale heavy duty air dropping device.

Description

technical field [0001] The invention mainly relates to the field of airbag buffer equipment, in particular to a multi-stage airbag joint buffer device that can effectively protect large-scale heavy-duty airdrop equipment from landing safely. Background technique [0002] In the prior art, airbag buffer equipment is often used to effectively protect the safe landing of airdrop equipment. For example, cushioning and protective airbags are often used for the safe landing of large-scale heavy-duty airdrop equipment. The key technology is to protect the safety of airdrop equipment and prevent the airdrop equipment from directly touching the ground and The airbag burst. Most of the existing airborne cushioning airbags use a single-chamber airbag device with a single structure. During the buffering process of this type of airbag device, there are always problems that the airdrop equipment directly touches the ground or rebounds or even overturns. Technical difficulties are mutual ...
