Description
Technical field
The present invention relates to equipment drop from the air safety protection field, and in particular to it is a kind of equipment drop from the air multi-stage gasbag collaboration buffering dress
It sets.
Background technology
Air bag buffer has been widely used for equipping airborne, unmanned plane time because of the features such as light-weight, energy-absorbing effect is good
The technical fields such as receipts, space flight return, and as the important component of equipment safety guarantee.
In actual equipment drops from the air landing mission, existing air bag buffer has the following problems.
In existing airborne equipment landing air bag buffer, most of single gasbag buffering dress single using structure
It sets, to cause the setting of gas chamber initial buffer air pressure excessively single and there are limitations, causes buffering effect limited.
Existing list gasbag buffer unit is vented outward by gas vent, to realize pressure release.But it is airborne in equipment
During landing buffer, if air bag buffer gas vent is excessive, there are problems that airborne equipment directly contacts to earth；If gas
Capsule buffer unit gas vent is too small, is easy to increase severely because of airbag chamber internal pressure and exhaust velocity causes air bag quick-fried slowly excessively outward
Broken, this will bring fatefulue damage to airborne equipment.
The shortcomings that in order to overcome the easy explosion of single gasbag buffer unit, the small part prior art has used double gasbag
The technical solution of buffer unit：Such as the patent " multi-stage gasbag combination buffer unit " of Publication No. CN1923617A, but it is this more
Grade gasbag combination buffer unit is limited so as to cause effective cushion stroke using nested structure；Such as Publication No.
The patent " double gasbag buffer unit " of CN1923618A, although to use air bag top air chamber gentle for this air bag buffer
The mounting means of capsule spirit room superposition, but still caused without other buffer units between air bag top air chamber and air bag spirit room
Imitate that cushion stroke is limited, and air bag top air chamber and air bag spirit room are two sseparated independent air chambers, cause two gas chambers without
Method carries out collaboration buffering to airborne equipment, therefore cannot play good buffering effect to airborne equipment.
Invention content
In order to overcome the above problem, the present invention to propose while solving the air bag collaboration buffer unit of above-mentioned various problems.
The technical solution adopted by the present invention to solve the technical problems is：A kind of airborne multi-stage gasbag collaboration buffering dress of equipment
It sets, including upper air bag, air bag tubing string and lower gasbag；Upper air bag, air bag tubing string and lower gasbag are installed by the way of superposition；
Setting locking ring device is connected with airborne equipment at the top of upper air bag；Upper inside air bag is upper airbag chamber, the upper upper gas of balloon surface setting
Capsule charge valve；The upper upper air bags valve of balloon surface setting, upper balloon surface are arranged with the overlapping junction of air bag column surface
Joint air bleeding valve one；It is air bag tubing string chamber inside air bag tubing string, air bag tubing string charge valve is arranged in air bag column surface；Air bag tubing string
Air bag tubing string air bleeding valve, air bag column surface and the overlapping junction on lower gasbag surface setting joint air bleeding valve two is arranged in surface；
It is lower gasbag chamber inside lower gasbag, lower gasbag charge valve is arranged in lower gasbag surface, and lower gasbag air bleeding valve is arranged in lower gasbag surface.
Preferably, the upper air bag is consistent with the size of the lower gasbag.
Preferably, the upper air bags valve is one-way exhaust valve, and upper air bags valve is evenly arranged along upper balloon surface.
Preferably, the air bag tubing string is evenly arranged between upper air bag and lower gasbag.
Preferably, the air bag tubing string air bleeding valve is one-way exhaust valve, and air bag tubing string air bleeding valve is equal along air bag column surface
Even arrangement.
Preferably, the lower gasbag air bleeding valve is one-way exhaust valve, and lower gasbag air bleeding valve is evenly arranged along lower gasbag surface.
Preferably, the joint air bleeding valve one is one-way exhaust valve, combines the number and air bag tubing string number of air bleeding valve one
Unanimously.
Preferably, the joint air bleeding valve two is one-way exhaust valve, combines the number and air bag tubing string number of air bleeding valve two
Unanimously.
The beneficial effects of the invention are as follows：The 1st point proposed for background technology, includes upper air bag, airsac tube using structure
Column, lower gasbag multi-stage gasbag collaboration buffer unit solve the problems, such as this.Wherein, upper air bag, air bag tubing string and lower gasbag can be with
Different initial buffer air pressures is set according to specific airborne landing conditions, to realize that the multistage in the airborne landing mission of equipment is slow
Punching.
The 2nd point proposed for background technology, present invention employs following designs：Upper air bag can pass through upper air bags valve
Outwardly exhaust pressure relief, can also be vented by combining air bleeding valve one to air bag tubing string, and the expansion of air bag tubing string realizes that level-one is slow
Punching；Air bag tubing string can also be arranged by combining air bleeding valve two to lower gasbag by the outside exhaust pressure relief of air bag tubing string air bleeding valve
Gas, lower gasbag expansion, realizes level 2 buffering；Lower gasbag can outwardly exhaust pressure relief, realization three-level be slow by lower gasbag air bleeding valve
Punching；Cooperate with the multi-buffer of buffer unit that can not only prevent airborne equipment from directly contacting to earth by air bag, moreover it is possible to realize that air bag cooperates with
The multistage release of buffer unit internal pressure, prevents air bag explosion, and ensures that airborne equipment safety lands.
For the 3rd point of background technology, the present invention is pacified by the way of the superposition of upper air bag, air bag tubing string and lower gasbag
Dress, rather than nested mode；The air bag tubing string is arranged between upper air bag and lower gasbag to increase effective cushion stroke, to
Effectively enhancing airbag apparatus buffering effect.Moreover, dividing between the upper air bag and air bag tubing string, air bag tubing string and lower gasbag of the present invention
Collaboration buffering is not carried out by combining air bleeding valve one and joint air bleeding valve two, therefore buffering effect well can be played to airborne equipment
Fruit.
Note：Above-mentioned design in no particular order, each all make the present invention compared with the prior art have difference and significantly into
Step.
