Description

A kind of space flight seat crash energy absorption equipment

Technical field

This utility model relates to space equipment technical field, is specially a kind of space flight seat crash energy absorption equipment.

Background technology

Along with the fast development of Aero-Space cause, the requirement to spacecraft component is more and more higher, ensures spacefarer simultaneously The life safety most important thing the most especially, in manned spaceship landing shock, spaceman protection is had important by seat buffer system Meaning, landing is the final step of human spaceflight operation, is also the final mark of manned space flight task success or failure, and return capsule enters The atmosphere stable decrease speed after parachute slows down is about 6～8m/s, and return capsule lands bigger by producing with this speed Impact acceleration, may cause damage to spaceman, consequently, it is desirable to install landing buffer gear absorb return capsule land time Energy, nowadays space flight seat buffer system technology is the most ripe, but along with the development of science and technology, needs safer, more just Just, sensitiveer space flight seat buffer device, current hydraulic damping technology, metal cutting technology, collapsing of metal tube are reacted Notch distortion technology etc. all can not better meet this requirement, for this it is proposed that a kind of space flight seat crash energy absorption equipment.

Utility model content

The purpose of this utility model is to provide a kind of space flight seat crash energy absorption equipment, to solve in above-mentioned background technology The problem proposed.

For achieving the above object, this utility model following technical scheme of offer: a kind of space flight seat crash energy absorption equipment, bag Including slide rail and support, two jiaos, the bottom of described support is equipped with slide rail, is bolted between described support and lifter, institute Stating lifter one end and connect chair cushion, arrange controller outside described chair cushion, the bottom of described chair cushion arranges pedal, and described foot Seat belt is installed on the top of pedal, and the inner chamber of described chair cushion arranges uplock and tensioner ring, described uplock and described piston rod it Between connected by piston rod, described uplock top connects pressure gas bag, described tensioner ring bottom and down lock compact siro spinning technology.

Preferably, described welding seat interface outside uplock；Between described tensioner ring and piston rod, conical ring is set.

Preferably, described piston rod embeds inside tensioner ring, and is slidably connected between piston rod and tensioner ring.

Preferably, described chair cushion mid portion is recessed.

Preferably, it is electrically connected with between described controller and lifter.

Preferably, it is slidably connected between described support and slide rail, and support can be moved in parallel by slide rail.

Compared with prior art, the beneficial effects of the utility model are: this space flight seat crash energy absorption equipment can make space flight Member keeps a kind of sitting posture curled in airship, provides comfortable, safe primary condition for spacefarer, the structural simulation people of seat The external form that body is complicated, to meet the optimal stress of human body, arranges a liter lifter, the supine position of regulation spacefarer, and passes through Controller realizes Automated condtrol, beneficially the prompt operation of spaceman, uses crash energy absorption equipment, incomplete by multiple wall thickness Identical tensioner ring is in series, and has a tensioner ring to rupture when expanding, do not interfere with the buffering of remaining tensioner ring in buffering course Function, improves the reliability of buffer for seats, and tensioner ring is by being as thin as thick setting, can be effectively reduced adding of output loads Speed increment rate, and have vibration-damping function, and this device to possess volume little, the feature such as light weight.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

Referring to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of space flight seat crash energy absorption equipment, including Slide rail 5 and support 3, two jiaos, the bottom of support 3 is equipped with slide rail 5, is bolted, lifter between support 3 and lifter 4 4 one end connect chair cushion 12, arrange controller 2 outside chair cushion 12, and the bottom of chair cushion 12 arranges pedal 6, and the top of pedal 6 Installing seat belt 1, the inner chamber of chair cushion 12 arranges uplock 10 and tensioner ring 8, between uplock 10 and tensioner ring 8 by piston rod 9 even Connecing, uplock 10 top connects pressure gas bag 11, tensioner ring 8 bottom and down lock 7 compact siro spinning technology.

Seat interface 13 is welded outside uplock 10；Conical ring 14 is set between tensioner ring 8 and piston rod 9；Piston rod 9 embeds Tensioner ring 8 is internal, and is slidably connected between piston rod 9 and tensioner ring 8；Chair cushion 12 mid portion is recessed；Controller 2 and lifter 4 it Between be electrically connected with；It is slidably connected between support 3 and slide rail 5, and support 3 can be moved in parallel by slide rail 5.

This utility model in use, utilizes the expanding deformation technology of thin-wall metal circular ring, Spacecraft Launch and aloft rail During road normal flight, buffer for seats is in down lock 7 one end, makes seat keep normal operation position, when return capsule will When returning to ground, pressure gas bag 11 is lighted a fire, and buffer for seats is risen to uplock 10 position by the high-pressure gas of generation, returns Reboard land moment time, if the outside impact load produced exceedes the threshold that buffer unit sets, buffer unit begins to fortune Dynamic, tensioner ring 8 passes sequentially through conical ring 14, and expanding phenomenon occurs, and outside impact energy is converted into the bullet of tensioner ring 8 material, moulds Frictional heat energy between property deformation energy and tensioner ring 8 and conical ring 14, thus reach the purpose of buffering energy-absorbing.
