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
The present invention is mainly concerned with air sac shock attenuation device field, refers in particular to a kind of multi-stage gasbag combination buffer unit that can be used to effectively protect the safe landing of large-scale heavy duty aerial delivery provisions.
Background technology
Often utilize in the prior art air sac shock attenuation device to aerial delivery provisions safe landing effectively protect; for example the safe landing of large-scale heavy duty aerial delivery provisions is commonly used to the buffer protection air bag, and its gordian technique is the safety of protection aerial delivery provisions and prevents that aerial delivery provisions from directly contacting to earth and the air bag explosion.In the existing airborne buffer air bag, most of structure mono-single chamber balloon device that adopts, this type of airbag apparatus always exist aerial delivery provisions directly to contact to earth or the big bounce even the problem of overturning, and these technical barriers is mutual containing in design in buffering course.Prevent big bounce if utilize big exhaust to reduce rigidity, just be easy to cause aerial delivery provisions directly to contact to earth; If adopt little exhaust to prevent that aerial delivery provisions from contacting to earth, then tend to reduce buffering effect and cause big bounce even overturn phenomenon.And in the airdrop mission of heavy drop equipment, the air bag explosion takes place in the air bag of single air chamber easily in the airborn landing process, and this will bring fatefulue infringement to aerial delivery provisions.
Summary of the invention
The technical problem to be solved in the present invention just is: at the technical matters that prior art exists, the invention provides a kind of simple in structure, easy and simple to handle, with low cost, can solve effectively that the large-scale heavy duty aerial delivery provisions directly contacts to earth and the easy explosion of single air bag etc. the multi-stage gasbag combination buffer unit of problem.
For solving the problems of the technologies described above, the solution that the present invention proposes is: a kind of multi-stage gasbag combination buffer unit, air bag and nested successively one or more outer air bag in it comprises, the outside of air bag in outer air bag is wrapped in; Offer air bag one-way vent in several in described on the air bag, offer several outer air bags holes on the outer air bag, it is characterized in that: total deflation hole area of several interior air bag one-way vent is greater than total deflation hole area in several outer air bags holes on the outer air bag on the described interior air bag.
Air bag and outer air bag are provided with the granny rag that is used for adjusting the pneumatophore shape in described, offer intercommunicating pore in the granny rag.
In described between air bag and the adjacent outer air bag and be provided with between the adjacent outer air bag and be used for the location drawstring of definite relative position.
Compared with prior art, advantage of the present invention just is: multi-stage gasbag combination buffer unit of the present invention adopts multistep staged venting energy-absorbing, can improve the safe reliability of buffer protection.The present invention can satisfy the particularly airdrop mission of heavy drop equipment of different aerial delivery provisions well, can effectively solve the problem of the existing air bag explosion of single air chamber aerial delivery provisions buffer air bag, can mediate aerial delivery provisions and directly contact to earth, short and safety factor of surge time problem such as low.And apparatus of the present invention are simple in structure, with low cost, be fit to use of large-scale production, simultaneously this shock absorber before inflation, take up space little, convenient disappointing the depositing in the back of landing.

The specific embodiment
Below with reference to the drawings and specific embodiments the present invention is described in further details.
As Fig. 1, Fig. 2 and shown in Figure 3, multi-stage gasbag combination buffer unit of the present invention, air bag 1 and nested successively one or more outer air bag 2 in it comprises, the outside of air bag 1 in outer air bag 2 is wrapped in, but interior air bag 1 is the air bag of exhaust, but outer air bag at different levels 2 is an exhaust on-inflatable air bag, and the interior air bag 1 inflation back outer air bag 2 of volume ratio is little, its volume ratio can according in the actual condition moment energy-absorbing the degree requirement, be optimized design; Interior air bag 1 and outer air bag 2 adopt the fiber cloth that certain intensity, good leak tightness are arranged to manufacture and form, do not have other mechanical auxiliary or packing material, only utilize the air of with low cost and environmental protection to carry out comprehensive effective protection to aerial delivery provisions.Offer air bag one-way vent 3 in several on the interior air bag 1, offer several outer air bags holes 4 on the outer air bag 2, total deflation hole area of several interior air bag one-way vent 3 is greater than total deflation hole area in several outer air bags holes 4 on the outer air bag 2 on the interior air bag 1.In the present embodiment, interior air bag 1 and outer air bag 2 are provided with the granny rag 5 that is used for adjusting the pneumatophore shape, offer intercommunicating pore 6 in the granny rag 5, and intercommunicating pore 6 makes the interior gas of air bag can free-flowing.Be provided with the location drawstring 7 that is used for determining relative position between interior air bag 1 and the adjacent outer air bag 2 and between the adjacent outer air bag 2.In the present embodiment, the outer air bag 2 of the volume ratio of interior air bag 1 is little, and its volume ratio is optimized design according to actual condition.Because the interior air bags hole more than 3 of interior air bag 1, thereby exhaust is rapid.And the outer air bags hole 4 of outer air bag 2 is less, and internally air bag 1 is little mutually for total deflation hole area, can be according to air bag in the actual condition optimal design 1 and outer air bag 2 exhaust velocities and flow.Adopt the synergy of multi-stage gasbag like this, air bag 1 is big in outer air bag 2 volume ratios, and not inflation in advance, generally can not break, and interior air bag 1 in buffering course if explosion suddenly, the effect of good moment energy-absorbing can be played on the contrary,, the effect of double insurance can be played to safe landing so improved safe reliability.During use, after internally air bag 1 charged into air in certain amount, interior air bag 1 had just had certain rigidity, and outer air bag 2 does not charge into gas before air-drop, and several outer air bags 2 are wrapped in interior air bag 1.When airborn landing moment, interior air bag 1 is subjected to the impact of aerial delivery provisions and volume reduces, pressure increases, the one-way exhaust valve meeting of adopting optimal design this moment is owing to the internal pressure effect is opened, a large amount of gases enter the outer air bag 2 adjacent with interior air bag 1 rapidly from the interior air bags hole 3 of interior air bag 1, thereby the gas pressure intensity of air bag 1 in reducing, the adjacent outer air bag 2 of this moment and interior air bag 1 is full of rapidly because of the moment exhaust of interior air bag 1 big flow, but, realize that moment impact can major part be absorbed because air bag 1 is big in outer air bag 2 volume ratios.Outer air bag 2 is in the gas filed while also exhaust; because the exhaust velocity of the outer air bag 2 by optimal design is 1 slower than interior air bag, flow lacks; beyond air bag 2 existing certain rigidity after inflation; also begin the slow venting energy-absorbing of subordinate phase simultaneously; can avoid directly the contact to earth problem of aerial delivery provisions after F/s big exhaust of moment, aerial delivery provisions is played good flexible protective effect all the time.
