Description
Technical field
The present invention relates to child safety seat field and in particular to locking can mechanism and side protection child safety seat.
Background technology
Human civilization and the progress and development of science and technology, make us have the vehicle of various difference 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 in the presence of inertia force with contact force, partes corporis humani's tissue will produce corresponding biomechanical response.Once tissue exceedes can recover the limit, to lead to solve brokenly disorganization or make normal physiological function impaired, decay or forfeiture, cause permanent damage, cause intracranial hemorrhage, faintness as fracture, tendon ligament rapture, Viscera rupture, swollen bleeding of becoming silted up, and cerebral concussion, nervous system is obstructed or blocks is lethal dying.For this to vehicle occupant：As spaceman, opportunity of combat driver, F1 equation racing driver, automobile passenger（Including child）Arise at the historic moment etc. emergent safety guard.
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; it is to cause tissue to be subject to different degrees of damaging, let us is analyzed one by one to existing safety guard technology：
1. spaceman safety guard uses technology：When spaceman lift-off and return ground; its acceleration and deceleration are very big; though subsiding using dorsad stress benzvalene form chaise longue, using honeycomb aluminum; broaching; the energy-absorbing cushion techniques such as tube extruding are consuming impact energy to protect spaceman safety; but the variable angle that spaceman produces relative to centrifugal force in running, make spaceman stress deviate its component of preferable damping, buffering track and still spaceman is produced with impact injury.
2. pilot, F1 equation racing driver's safety guard uses five-point type to fetter technology：Five-point type constraint technology is to limit occupant's displacement, prevents and vehicle components occur direct collision, by inertia force be dispersed to driver and crew two take on, costa sternaless, two thigh hipbones and crotch, increase stress point face, reduce the pressure of unit area.Simultaneously using the energy-absorbing expanded material intussusception impact energy such as EPP; but these technology can only play certain protective effect in relative velocity interval; but head by five-point type restraint system spacing when still to direction of motion displacement, its head inertia force cervical vertebra tendon ligament will be caused damage.When crossing shock peak value, its counteracting force also will bring secondary injury to occupant, when particularly headrest is clashed in head back motion, can cause cerebral concussion, cause multiple physiology reflections.
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, playing head cushioning effect and reaching prevents 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, lead to human body to be scurried out from preposition watch box fetters and lead to a disaster.Again because of individual variation, head is contacted with preposition watch box and is not ensured 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 having its dropped stitch fabric of the foldable advantage of small volume not yet to develop maturation is still that concept technology fails to list always so far.
5. automobile safety protector technology：Existing automobile all to protect driver and crew to reduce injury when clashing into using the technology of inclined type seat belt and air bag.This protection device can protect driver and crew's life within the scope 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, will produce great impact to head part, though not lethal; but its biological respinse equally can give people to bring different degrees of injury, such 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; using padded coaming come 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; reduce effect on human body pressure; impulsive force can be absorbed; impact energy can be pinned again, personnel's significantly displacement can be prevented, buffering protection function can be played to head again; the anti-power of work after impact peak value can be absorbed, the secondary damage to occupant for the counteracting force can be reduced again.
Protect the safety of occupant to greatest extent, so that occupant is escaped injury is face great of manufacturing enterprise of global each universities and colleges, scientific research institution and safety guard and the problem of complexity.

The multi-buffer body that the present invention is made up of base assembly, backrest assembly, foot-operated board component, a ring unlocking mechanism, anti-splashing protection shade assembly, safety belt assembly, head pillow mechanism etc..Using the combination of Shang Xu mechanism, the artificial Ge Bu elastic damping mechanism causing seat produces relative displacement with base（Increased multiple elastic damping inertial systems）The organic assembling of these elastic damping systems produces relative displacement and changes the direction of power, make these multiple buffer gears by impulse inertia power dissipation to the sub-agencies of each elastic damping, allow instantaneous maximum impact peak value to change in seat movement travel to increase, the acceleration of unit interval significantly reduces, the normal pressure that i.e. human body is impacted with seat contact point significantly declines, and part impact energy can be pinned in the middle of lockable mechanism the active force discharging to reduce secondary injury of counteracting force energy.Its automatic synchronization safety guard using self inertia plus seat belt drive backboard axle make a concerted effort overcome automatic synchronization safety guard mechanism spring energy, open rapidly within the extremely short time, when splash not yet flies out, covered human body to reach and protect an occupant from its evil.Ad hoc adjustable footrest mechanism, is unlikely to leg and hangs for a long time when taking for a long time, causes to oppress leg blood vessel, leads to blood flow freely not cause numbness and discomfort, simultaneously the stability of lifting children's ride-on, comfortableness.
1. a ring unlocking mechanism only need to pull draw ring can unlock in unblock, and dismounting is efficient and convenient.Avoid existing various safety seat and with the hands must draw group unblock office, operation facility at the rear portion of seat in narrow and small motor space；
2. ride the detachable square tube head being installed on base of board component, can dismantle as needed and install, pedal can move up and down and be adjusted to suitable position, make the stability of children's ride-on be unlikely to long-time leg and hang compressing leg blood vessel to lead to blood flow freely not cause numbness and discomfort, improve children's ride-on comfortableness.
3. seat buffering energy-absorbing mechanism structure principle：Seat assembly buffering energy-absorbing mechanism is made up of base assembly, backrest assembly, spring buffer sleeve, seat board, backboard, two-way slide bar buffer gear, seat belt.
When colliding, square tube except base is locked by ISOFIX, the inertia force of remaining upper parts and child's gross mass forces seat anterior displacement, linkage is complied with anterior displacement, seat upwards first and is anteriorly lifted from the parallel buffering above position of slide bar, when moving further along, afterwards when short connecting rod decline and cause whole seat to rotate an angle, make inertia force forward resolve into two component forward and up, reduce seat belt and act on the pressure on two shoulders.
Human body inertia force forward pulls sleeve pipe through seat belt, and buffering energy-absorbing function is played in the spring stress compression of two-way slide bar buffer gear, and seat belt acts on human body two shoulder stress and buffered.After quill crosses the dead point of two-way slide bar buffer gear, in spring tension release, backboard axial direction preacceleration displacement, act on human body two shoulder stress to be unloaded, when backboard axle moves to the front end of kidney slot, sleeve pipe drives backrest frames, with respect to the pin joint of base, rotation forwards occurs, and the spring buffer sleeve between backrest frames and base is compressed, and plays buffering energy-absorbing damping action again；Meanwhile, seat board is worn the base plate slide-bar connecing and also simultaneously work as buffering energy-absorbing function under the damping action of real estate management's inner spring.
When shock reaches peak value, i.e. seat moves forward to and will produce counteracting force backward during extreme position, spreading formula lock-stopping hinge moves band ratchet and ratchet latch hook simultaneously and hooks and closes after opening restriction front rod, all movement parts counteractive inertia total amount of seat upper portion will be locked out and limit its displacement and reduce reaction punch power.Now side plate, backboard, seat board certainly will chest-to-back acceleration displacements under releasable counteracting force in spring buffer sleeve, square tube inner spring and two-way slide bar buffer gear spring; human body also will accelerate position backward under counteracting force; because of displacement in the same direction; its speed difference will lead to pulling force in the case of seat belt is pulled back for the human body to substantially reduce; remaining impulsive force is again by the spring of two-way slide bar buffer gear; and the bidirectional spring in square tube to buffer further; reduce the load of secondary pulse to greatest extent, effective protection human body sustains damage.
4. the combination of back pad seat cushion, headrest mat structure are combined by surface fabric and EPP expanded material, this pad ergonomically form Design be equipped with some through holes, when human body acts on seat cushion, its compression area deforms rapidly, parcel supports body surface area to greatest extent, reduce unit area pressure, add that backboard pond, seat board pond built-in foam pad compound action sufficiently reach energy-absorbing buffering effect, reduce the peak pressure acting on human body to greatest extent.Headrest bolster presses human body head form force design, is equipped with some through holes in headrest periphery, is allowed to deform to fit well with head soon when head is with headrest collision and reduces the pressure of unit area.
Simultaneously when there is side collision, when the through hole of headrest bolster side setting can prevent child's ear from clashing into, the pressure of external ear road gas compression, reduces skyrocketing of external auditory meatus gas column pressure, can prevent tinnitus, tympanic member perforation.
5. safety belt assembly one key unblock subsidiary head displacement energy-absorbing bag buffering restraint system structural principle
Seat belt bilateral shoulder belt upper end is connected with backboard axle, and lower end constitutes a key unblock restraint system with tightening up actuator through seat belt unlocking device around under seat board；Head displacement buffer unit is placed on seat belt by safety belt protecting casing, and it is overall that buffering shield bag and safety belt protecting casing constitute adjustable one.Do not collide under normal circumstances, buffering shield bag is put and gives child front and child's lower jaw to have a certain distance, and when colliding, human body anterior displacement to seat belt fetters extreme position（I.e. seat belt is tightened human body and is no longer moved forward by seatbelt restraint; head is under inertia force effect still to preshoot; head still continues forward displacement because no constraining; now buffers packet is touched with the lower jaw of children head; head is inhaled under flexible situation in buffering shield bag; effectively cushioned head displacement, plays a very good protection to the cervical vertebra of child, tendon ligament.
6. headrest energy-absorbing releases energy buffer gear structural principle
Knowable to child safety seat dummy's crash tests video, when peak value is crossed in collision, the release of human body and seat each stress interior energy will make child under reaction force acts with very high acceleration to reverse displacement, head is produced with headrest and clashes into, can be to cervical vertebra or cerebral concussion equivalent damage.
The present invention protects child's cervical vertebra and head using two-way slide bar buffer gear.When colliding, once reaching shock peak value, human body is in the presence of counteracting force, by rapid rearward displacement, back contact back pad is obstructed head still rearward displacement this moment, the headrest buffering energy-absorbing of the present invention and the rocking arm elastic damping mechanism releasing energy, when head is by clashing into headrest, headrest will be compressed to priming lever spring in the presence of counteracting force, reduced rapidly because headrest damps, by spring force, the speed that it runs backward, and head and headrest are because moving in the same direction, reduction power acceleration makes head and the impact force of the contact of headrest weaken, when exceeding priming lever spring compression travel minimum point, spring expansion force makes headrest accelerate rearward displacement, so head and the contact force of headrest will be unloaded.Remaining footprint pressure will be by headrest Soft Roll（EPP expanded material）Absorb, make the counteracting force of children head absorb degraded to greatest extent, effectively control the secondary injury that counteracting force causes to children head.
When there is side collision, the rocking arm elastic damping mechanism of headrest will produce lateral displacement, add headrest Soft Roll headrest bolster（EPP expanded material）Side arranges the pressure of external ear road gas compression when some through holes can prevent child's ear from clashing into, and reduces skyrocketing of external auditory meatus gas column pressure, can prevent tinnitus, tympanic member perforation.
7. automatic synchronization anti-splashing thing safety guard mechanism structure do not collide normal condition when, by two groups of left and right cluster spring）Tarpaulin is made to be in closure state in the presence of prestressing force, once the automatic synchronization anti-splashing thing safety guard that collides overcomes spring under the dual function motive force that self inertia power and seat belt pull backboard axle（T-15）Tension force; make the spring line of force exceed tarpaulin and fix axle bed centrage; the contractility of spring will make tarpaulin fully open; cover facing material draws bulletproof fabric using slim Kev; this covers on inertia force, belt force, the contractility of spring can fully open under synchronously driving in most time; i.e. this cover spills prior to splash and opens, and this cover is fully able to prevent the injury to occupant for the splash, implements to protect comprehensively.
If after colliding, when need to save occupant, tension force of spring is overcome to make spring as long as lifting tarpaulin bar（T-15）Line exceedes tarpaulin fixation axle bed with joint efforts（T-12）Centrage, spring（T-15）Contractility tarpaulin will be made to pack up and without locking system（.
8. unidirectional elastic endergonic buffer gear structural principle is protected in handrail and side
Handrail and side protect unidirectional elastic endergonic buffer gear to form its assembly relation by outside steel wire, inner side steel wire, fixed plate, establishment sheath; human body is when seat Inside To Outside extrudes; the outside deformation displacement of steel wire assembly can be made with less power; when by external force steel wire assembly by outside phase inside displacement when; once reaching leverage movement dead; steel wire assembly then can not be to inner side deformation displacement, admittedly playing the effect of protection occupant.
After the technical program, according to the impact force curve of laboratory simulation impact test, devise multistage buffer system, collaborative by multi-buffer system, reduce the peak value impacting force curve during collision, effectively reduce the extent of injury for human body for the impact；Take into full account the bounce problem after impact peak value simultaneously, entered row buffering using twice Suo Neng mechanism and two-way spring buffer mechanism, simultaneously auxiliary honeycomb EPP lamp softness implant buffering, in order to reduce impact.It has been specifically designed anti-splashing protection shade assembly, in order to the injury to human body for splash when preventing from clashing into.Buffer gear in the technical program favorably uses inertia active buffer, when favorably being moved forward with human body, a series of passive buffering that seat belt pulls sleeve pipe and touches, and buffering settings at different levels are reasonable, collaborative buffering energy-absorbing, and buffering effect is obvious.
