Background technology
Human civilization and the progress and development of science and technology, make us have the vehicle of various different purposes, with notDifferent field is operated in mode and speed.When these vehicle accidents collide, occupant will be in a machineIn tool shock loading environment, under the inertia force effect with contact force, partes corporis humani's tissue rings producing corresponding biomechanicsShould.Once tissue exceedes and can recover the limit, will cause solving brokenly disorganization or making normal physiological function impaired, decay orLosing, i.e. cause permanent damage, as fracture, tendon ligament rapture, Viscera rupture, silt are swollen hemorrhage, and cerebral concussion causes intracranialHemorrhage, faint, nervous system is obstructed or blocks is lethal dying.For this to vehicle occupant: such as spaceman, opportunity of combat driver,The F1 equation emergent safety guard such as driver, automobile passenger (including child) of competing for speed arises at the historic moment.
The technology of comprehensive existing various safety guards, cuts both ways.These safety guards are in relative velocity districtPlay certain protective effect in although, but injury to occupant can not be greatly lowered, human body and safety guard structureHuge pressure will be born in part contact position, be to cause tissue to be subject to damage in various degree, and existing safeguard protection is filled by let usTechnology of putting is analyzed one by one:
1. spaceman safety guard uses technology: when spaceman lift-off and return ground, its acceleration and deceleration are veryGreatly, though use dorsad stress benzvalene form chaise longue, use honeycomb aluminum to subside, broaching, the energy-absorbing cushion technique such as tube extruding disappearsConsumption impact energy is to protect spaceman safety, but the variable angle that spaceman produces relative to centrifugal force in running,Make spaceman stress deviate preferable its component of damping, buffering track and still spaceman is produced impact injury.
2. pilot, F1 equation compete for speed driver's safety guard use five-point type constraint technology: five-point typeConstraint technology is to limit occupant's displacement, prevents and vehicle components generation direct collision, inertia force is dispersed to driver and crewTwo shoulders, costa sternales, two thigh hipbone and crotches, increase stress point face, reduces the pressure of unit are.Use the energy-absorbings such as EPP simultaneouslyExpanded material intussusception impact energy, but these technology can only play certain protective effect in relative velocity interval, but headBy five-point type restraint system spacing time still to direction of motion displacement, cervical vertebra tendon ligament will be caused damage by its head inertia forceWound.When crossing shock peak value, occupant also will be brought secondary injury by its counteracting force, particularly head back motion impact headDuring pillow, cerebral concussion can be caused, cause multiple physiology to reflect.
3. child safety seat preposition watch box security protection technology: children's safety preposition watch box technology: this technology usesLarge area stops displacement mode, makes human body impact force action reduce unit pressure in large area cushion pad, and head displacement can be madeFor this device cushion pad, play head cushioning effect and reach to prevent cervical vertebra cervical muscle ligament injury, but this method makes human bodyThorax abdomen stress but unfavorable to internal organs, and because of undirected upper force constraint, cause human body to be scurried out from preposition watch box fetters and lead to a disaster.Again because of individual variation, head contacts with preposition watch box and does not ensures that and accurately strike on preferable cushion pad, and head is likely toStrike on preposition watch box skeleton, be likely to result in lisp, cervical spine injury.
4. inflated portable safety guard: inflated portable safety guard, though there being volume I sheet-prevalentIts dropped stitch fabric not yet develop maturation be still so far concept technology always fail listing.
5. automobile safety protector technology: existing automobile all uses the technology of inclined type seat belt and air bag to protectProtect driver and crew and reduce injury when clashing into.This protection device can protect driver and crew's life in the range of relative velocity,But occupant can not be protected injury-free, and when human body inertia force is bound to the limit by seat belt, huge inertia force would potentially result inClavicle, breastbone, shoulder potassium bone are fractured, and air bag reaching 300Km/h once opening its speed, head part will be produced great impact, though notLethal, but its biological respinse can bring to people equally and injure in various degree, as cerebral concussion causes faintness or even intracranial hemorrhage etc..
Summary existing safety guard technology, its technical characteristic is that restriction personnel's displacement prevents human body and delivery workTool component directly collides, and utilizes padded coaming to carry out apparatus with shock absorbing, plays certain guarantor in certain velocity intervalProtecting effect, if outpacing scope, adding individual variation, it is impossible to ensure occupant safety.
When vehicle collides, how to make occupant reduce acceleration, i.e. reduce effect on human body pressure, can absorbImpulsive force, can pin again impact energy, can prevent personnel's significantly displacement, head can be played buffering protection function again, bothThe anti-power of work after impact peak value can be absorbed, the counteracting force secondary damage to occupant can be reduced again.Protect occupant to greatest extentSafety, making occupant escape injury is that global each universities and colleges, the manufacturing enterprise of scientific research institution and safety guard faceGreat and the problem of complexity.
