Combined air-drop cushion airbag that can actively and synchronously open and exhaust quickly

Abstract

The combined air-drop buffer airbag that can be actively and synchronously opened and exhausted quickly includes a plurality of rectangular air-drop buffer airbags arranged side by side in the horizontal direction. The top of each air-drop buffer airbag is provided with an air inlet. An air intake nozzle is provided, and an exhaust port is respectively provided on the side wall of each airdrop buffer airbag, and a quick-opening exhaust valve is respectively provided at each exhaust port; each quick-opening exhaust valve includes a valve seat , the top end surface of the valve seat can be attached to the lower surface of the valve cover, the right side of the valve cover edge is fixedly connected with the inner end of the right connecting plate, and the outer end of the right connecting plate is provided with an upper piercing hole along the vertical direction . Its purpose is to provide a stable and reliable working performance, which can quickly and synchronously open the exhaust ports of multiple cushion airbags used in the same equipment, thereby stabilizing the cushioning performance of the cushion airbags, effectively reducing or avoiding the equipment from being overturned or even overturned. The damaged combined air-drop cushion airbag that can actively and quickly release the air simultaneously.

Description

Technical field [0001] The invention relates to a combined airdrop buffer airbag capable of actively synchronously opening and exhausting. Background technique [0002] If the equipment directly touches the ground after landing after parachute, the instantaneous impact overload will damage the mechanical structure of the equipment and the internal equipment. Therefore, a part of the impact energy needs to be absorbed by an energy absorption device. The widely used energy absorbing devices mainly include compressible materials, braking rockets, and cushioning airbags for airdrops. Compared with other energy absorbing devices, the airdrop cushion airbag has the advantages of simple structure, convenient use, good cushioning effect and low cost. The airbag cushioning system mainly uses the cushioning of the airbag to absorb most of the impact energy during landing and reduce the impact of the equipment at the moment of landing. Due to the many advantages of airdrop cushioning air...

AI Technical Summary

Problems solved by technology

However, when the equipment is large in size and needs to use multiple airbags at the same time, there will also be a time difference between the opening of the exhaust ports of each airbag, which will cause the equipment to overturn or even overturn, causing serious damage to the equipment.
