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 vehicle of various different purposes, operate in different field with speed by different way.When these vehicle accidents collide, occupant will be in mechanical impact load's environment, and under the inertia force effect with contact force, partes corporis humani's tissue will produce corresponding biomechanical response.Once tissue exceedes and can recover the limit, to cause solving brokenly disorganization or making normal physiological function impaired, decay or forfeiture, i.e. cause permanent damage, as fracture, tendon ligament rapture, Viscera rupture, silt are swollen hemorrhage, and cerebral concussion causes intracranial hemorrhage, faintness, 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.Although these safety guards play certain protective effect in relative velocity interval; but injury to occupant can not be greatly lowered; huge pressure will be born in human body and safety guard component contact position; being to cause tissue to be subject to damage in various degree, existing safety guard technology is analyzed by let us one by one:
1. spaceman safety guard uses technology: when spaceman lift-off and return ground; its acceleration and deceleration are the biggest; though using stress benzvalene form chaise longue, use honeycomb aluminum dorsad to subside; broaching; the energy-absorbing cushion techniques such as tube extruding consume impact energy 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 type constraint technology be restriction occupant's displacement; prevent and vehicle components generation direct collision; inertia force is dispersed to driver and crew two take on, costa sternales, two thigh hipbone and crotches; increase stress point face, reduce the pressure of unit are.Use the energy-absorbing expanded material intussusception impact energys such as EPP simultaneously; but these technology can only play certain protective effect in relative velocity interval; but head by 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 force.When crossing shock peak value, occupant also will be brought secondary injury by its counteracting force, when particularly headrest is clashed in head back motion, can cause cerebral concussion, 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 to stop displacement mode; human body impact force action is made to reduce unit pressure in large area cushion pad; head displacement may act on this device cushion pad; play head cushioning effect to 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 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 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 have its dropped stitch fabric of volume I sheet-prevalent not yet develop maturation be still so far concept technology always fail listing.
5. automobile safety protector technology: existing automobile all uses the inclined type seat belt technology with air bag to protect driver and crew to 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; when human body inertia force is bound to the limit by seat belt; huge inertia force would potentially result in clavicle, breastbone, shoulder potassium bone fracture; air bag reaches 300Km/h once opening its speed, head part will be produced great impact, though the most lethal; 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 from directly colliding with vehicle components; padded coaming is utilized to carry out apparatus with shock absorbing; certain protective effect is played in certain velocity interval; if outpacing scope; plus individual variation, it is impossible to ensure occupant safety.
When vehicle collides; occupant how is made to reduce acceleration; i.e. reduce effect on human body pressure; impulsive force can be absorbed; impact energy can be pinned again, personnel's significantly displacement can be prevented, head can be played buffering protection function again; the anti-power of work after impact peak value can be absorbed, the counteracting force secondary damage to occupant can be reduced again.Protect the safety of occupant to greatest extent, make occupant escape injury and be face great of global each universities and colleges, the manufacturing enterprise of scientific research institution and safety guard and the problem of complexity.

The present invention is formed its assembly relation by base assembly and hand basket assembly two large divisions, front dorsad can install by adjusting the side of hand basket, installs the most forward two kinds of forms.Safety seat base energy-absorbing buffering mechanism, retroaction energy lockable mechanism, base and carry blue is connected locking and unlocking mechanism, carry the buffer gear of indigo plant, the composition such as the mechanism of sunshade function, side protection mechanism held concurrently by seat cushion and headrest, Ti Lan handle mechanism structure, seat belt, anti-splashing thing safety guard, using the organic assembling chatting comprehensive organ, the artificial bottom buffer gear each with the top of seat causing seat produces relative displacement.These elastic damping systems produce relative displacement in collision process and change the direction of power, allow the impulse inertia power dissipation of gross mass in the sub-agencies of each elastic damping, make to act on human body instantaneous maximum impact peak value to increase in seat movement travel, the acceleration of unit interval reduces, i.e. human body significantly declines with the impact normal pressure of seat contact point, when crossing shock peak value, the impact energy of partial reaction power is pinned by lockable mechanism simultaneously, reduces the impact reactive force secondary injury to child.
1. the cushioning principle of this safety seat:
(1). the buffering of base assembly: when colliding, except base is forced seat anterior displacement by the lock inertia force of remaining upper parts and child's gross mass of ISOFIX, first linkage complies with upwards anterior displacement, on buffering slide bar and above parts, front upper place is to lifting, after when travelling forward, short connecting rod decline causes whole seat to rotate an angle, inertia force forward is made to resolve into two component forward and up, decomposition pressure on human body.The damping action of bar linkage motion mechanism is played in the extension spring of base both sides.Hand basket assembly inertia forward drives lock machine assembly forward simultaneously, and now, before and after buffering slide bar, spring assembly hand basket assembly provides two-way damping buffering；
(2). the buffering of hand basket assembly: the seat board in hand basket has three slide-bars of upper, middle and lower to slide in the kidney slot of side plate, and upper and lower two slide-bars carry out two-way damping buffering by spring rocker arm body, in hand basket, in swing, dress swings whole seat board；
(3). seat belt is installed on seat board, and the tail end of seat belt is enclosed within slide-bar, and child and seat board are fixed as an entirety, seat belt is cased with and the buffering slided protects bag, the head of child is lifted gentle punching, it is to avoid the damage of cervical region；
(4). the flexible package buffering on the parts such as seat board, side protection, headrest, energy-absorbing further.
(5). two-way rocking arm, the bidirectional spring etc. of buffering slide bar are all to provide two-way buffering, meet buffer requirement when knocking into the back and knocked into the back.
(6). base connecting rod buffer gear be provided with Suo Neng mechanism, the retaining mechanism when reaching the limit of position, prevent its Powerful Rebound from causing secondary injury.
2. the unblock principle of safety seat:
(1). the unblock principle of seat base: the seat ISOFIX fixing axle to the ISOFIX that prospective vehicle is preset, one push away i.e. lockable gently, during unblock, only need to pull draw ring, draw ring drives unblock steel cable to pull can unlocking of ISOFIX.Dismount efficient and convenient, it is to avoid in narrow and small motor space, with the hands rear portion at seat is drawn to dial and unlocked office.
(2). the unblock of hand basket assembly: no matter before dorsad or when phase premise indigo plant connection bearing pin in face enters former and later two mounting seats, dead bolt overcomes the tension force of spring to fall into mounting seat bottom land under downforce component effect, locking is put forward blue support shaft by dead bolt under the action of the spring, now base is connected as a single entity with putting forward indigo plant, dead bolt is provided with the inclined-plane of two angles, wherein: ramp is easy for the smooth and easy insertion of support shaft；Lower inclined plane eliminates support shaft and supports the effect of seat gap.When need to by base with when carrying blue the disengaging, only need to pull after carrying on unblock pull bar and be placed in solution lock hook slot, the unblock steel wire unlocking pull bar two ends draws bracing wire runner through directive wheel, the take-up while of when bracing wire runner rotates, being pulled out by forward and backward dead bolt, base is with to put forward indigo plant the most disengagable.
3. handle optional position is spacing: by coordinating of ball and ball-type groove so that handle can stop spacing in rotation process at an arbitrary position, and tarpaulin coordinates handle that tarpaulin can be made to rest on optional position simultaneously, easy to use；Handle is provided with coordinating of latch and locking groove, during handle is mentioned up and down, drives latch to coordinate stop in locking groove, prevents the 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, after colliding, 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 and prevents from splashing；When forward is installed, after colliding, handle adding inertia due to counterweight, handle rotates forward, drives tarpaulin strut rotating opening tarpaulin forward by dismountable connection, prevents the injury of splash.
Buffer gear in the technical program has taken into full account the situation of various collision; do two-way buffering to relate to, by the buffering energy-absorbing of spring, and think the impact peak value adding buffer distance to reduce collision; child can be protected comprehensively and effectively, reduce injury；The seat simultaneously simplified and the unlocking manner of hand basket so that convenient for unlocking is fast；Creatively consider the protection of splash, devise the splashing opening mechanism of linkage, and splatter guard when considering forward and reverse installation.
