Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] As shown in Figure 1, Figure 2 and Figure 3, the double-chamber airbag cushioning device of the present invention includes an airbag body 7, which is made of fiber cloth with a certain strength and good airtightness, without other mechanical Auxiliary parts or filling materials, only use low-cost and environmentally friendly air to effectively protect the airdrop equipment in all directions. According to the needs of actual working conditions, the airbag body 7 can be designed as a circle, a square, an ellipse or other shapes. The airbag body 7 is divided into independent airbag top air chamber 1 and airbag bottom air chamber 2 from top to bottom. The airbag top air chamber 1 is a closed air chamber that does not exhaust externally. The airbag bottom air chamber 2 is provided with a bottom air chamber vent hole. 5. A one-way e...

Abstract

This airbag bumper of a double air chamber comprises of pneumatophores that have independent upper airbag chambers and lower airbag chambers top to bottom. Upper airbag chamber is enclosed and the lower airbag chamber has venting holes. Upper airbag chamber is thin in the middle and thick at the ridge and the lower airbag chamber is thicker and bigger. This airbag bumper with a double air chamber is simple in structure, convenient in operation, low of cost, and effective in solving the rebound, reverse and direct landing of equipments of the light and precise air dropping device in buffer landing.

Description

technical field [0001] The invention mainly relates to the field of airbag buffer equipment, in particular to a double-chamber airbag buffer device that can effectively protect light precision 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 light precision equipment such as unmanned reconnaissance aircraft. Prevent rebounding, overturning, and airdrop equipment directly touching the ground. 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 checks and balances. If a large exhaust is used to pr...
