Description
Technical field
The present invention relates to a kind of child safety seat, be specifically related to baby's two-way basket type safety seat.
Background technology
Human civilization and the progress and development of science and technology, make us have the delivery vehicle of various different purposes, with not
Operate in different field with mode and speed.When these delivery vehicle accidents collide, occupant will be in a machine
In tool shock loading environment, under the effect with contact force for the inertia force, partes corporis humani's tissue rings producing corresponding biomethanics
Should.Once tissue exceedes and can recover the limit, will cause Xie Poxue disorganization or make normal physiological function impaired, decay or
Losing, i.e. causing permanent damage, as fracture, tendon rupture of ligament, Viscera rupture, silt are swollen bleeding, and cerebral concussion causes encephalic
Bleeding, faintness, nervous system is obstructed or is blocked is lethal dying.For this to delivery vehicle occupant: such as astronaut, opportunity of combat driver,
The F1 equation emergent safety guard such as driver, automobile passenger (including children) 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 district
Although interior play certain protective effect, but injury to occupant can not be greatly lowered, human body and safety guard structure
Huge 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 us
Technology of putting is analyzed one by one:
1. astronaut's safety guard uses technology: when astronaut's lift-off and return ground, its acceleration and deceleration are very
Greatly, though use dorsad stress benzvalene form chaise longue, use honeycomb aluminum to subside, broaching, the energy-absorbing cushion technique such as tube extruding disappears
Consumption impact energy is protecting astronaut's safety, but the variable angle that astronaut produces relative to centrifugal force in running,
Preferable its component of damping, buffering track of astronaut's stress deviation is made still to produce impact injury to astronaut.
2. pilot, F1 equation compete for speed driver's safety guard use five-point type constraint technology: five-point type
Constraint technology is to limit occupant's displacement, prevents and vehicle components generation direct collision, inertia force is dispersed to driver and crew
Two shoulders, sternal rib, two thigh hipbones and crotch, increase stress point face, reduces the pressure of unit are.Use the energy-absorbings such as EPP simultaneously
Expanded material intussusception impact energy, but these technology can only play certain protective effect in relative velocity is interval, but head
By five-point type restraint system spacing when still to direction of motion displacement, cervical vertebra tendon ligament will be caused damage by its head inertia force
Wound.When crossing shock peak value, occupant also will be brought secondary injury by its reaction force, particularly head back motion impact head
During 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 uses
Large area stops displacement mode, makes human body impact force action reduce unit pressure in large area cushion pad, and head displacement can be made
For this device cushion pad, play head cushioning effect and reach to prevent cervical vertebra cervical muscle ligament injury, but this method makes human body
Thorax abdomen stress but unfavorable to internal organs, and because of undirected upper force constraint, cause human body to be scurried out from the constraint of preposition watch box and lead to a disaster.
Again because of individual difference, head contacts with preposition watch box and does not ensures that and accurately strike on preferable cushion pad, and head is likely to
Strike 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-prevalent
Maturation not yet developed by its dropped stitch fabric is still that concept technology fails to list always so far.
5. automobile safety protector technology: existing automobile all uses the technology of inclined type safety belt and air bag to protect
Protect 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 safety belt, huge inertia force would potentially result in
Clavicle, breastbone, shoulder potassium bone fracture, air bag reaching 300Km/h once opening its speed, will produce great impact to head part, though not
Lethal, but its biological respinse can bring to people equally and injure in various degree, as cerebral concussion causes faintness or even intracranials hemorrhage.
Summary existing safety guard technology, its technical characteristic is that restriction personnel's displacement prevents human body and delivery work
Tool component directly collides, and utilizes padded coaming to carry out apparatus with shock absorbing, plays certain guarantor in certain velocity interval
Protecting effect, if outpacing scope, adding individual difference, it is impossible to ensure occupant safety.
When delivery vehicle collides, how to make occupant reduce acceleration, i.e. reduce effect on human body pressure, can absorb
Impulsive force, can pin again impact energy, can prevent personnel's significantly displacement, can play buffering protection function to head again, both
The anti-power of work after impact peak value can be absorbed, the secondary damage to occupant for the reaction force can be reduced again.Protect occupant to greatest extent
Safety, making occupant escape injury is that global each universities and colleges, the manufacturing enterprise of scientific research institution and safety guard face
Great and the problem of complexity.

Unlocking to pull after carrying on pull bar and being placed in solution lock hook slot, the unblock steel wire unlocking pull bar two ends draws bracing wire runner through directive wheel,
Forward and backward dead bolt is pulled out by take-up simultaneously when bracing wire runner rotates, and base and hand basket are i.e. disengagable.
3. handle optional position is spacing: by coordinating of ball and ball-type groove so that handle can be in rotation process
Staying at random location is spacing, and tarpaulin coordinates handle that tarpaulin can be made to rest on optional position simultaneously, easy to use；Handle is provided with
Latch coordinates with locking groove, during handle is mentioned up and down, drives latch to coordinate stop in locking groove, prevents hand basket
Swing when being used alone.
4. anti-splashing safety guard mechanism: tarpaulin push rod is linked with lower slide-bar by connecting rod, when installing dorsad, collides
After, lower slide-bar moves forward, and pulls connecting rod, and connecting rod drives tarpaulin push rod to rotate, and tarpaulin push rod drives tarpaulin strut to rotate, and opens
Tarpaulin prevents from splashing；When forward is installed, after colliding, owing to counterweight adds inertia on handle, handle rotates forward, logical
Cross and dismountable connection drive tarpaulin strut rotating opening tarpaulin forward, prevent the injury of splash.
Buffer gear in the technical program has taken into full account the situation of various collision, has done two-way buffering and has related to, logical
Cross the buffering energy-absorbing of spring, and think and add buffer distance to reduce the impact peak value of collision, can comprehensively and effectively
Protection children, reduce injury；The seat simultaneously simplifying and the unlocking manner of hand basket so that convenient for unlocking is fast；Creatively examine
Splatter guard when having considered the protection of splash, devised the splashing opening mechanism of linkage, and considered forward and reverse installation.
