Abstract
The invention relates to a device for absorbing energy for a special seat for a child to sit in an automobile when automobiles are in head-on collision. The device is characterized by consisting of a square framework 1, a fixed shaft 2, a front envelop 3, an extrusion head 4, a cushion block 5, extruding sheets 6, washers 7, a sliding bush 8, a seat board 9 and a rear envelop 10. According to the energy-absorbing framework for the child seat, under the action of acceleration generated when the automobiles are in the head-on collision, the child and the seat generate axial displacement, so that the energy-absorbing framework is driven to absorb energy. Through the cooperation of the energy-absorbing device and the conventional child seat with a seat belt, the purpose of protecting the child is achieved.
Description
Technical field
The present invention relates to, when automobile generation head-on crash, the endergonic a kind of device of automobile specified seat of children's ride-on.
Background technology
At present, when automobile generation head-on crash, no matter the safety measure of various child seat is the baby seat of backward installation, or the child seat of forward (comprising booster seat) is all rely on to use the safety on automobile to bring child protection.For this tender and lovely and fragile health of infant, bear the impulsive force under the accelerating action the same with adult, only rely on this safety method to be far from being enough.
Summary of the invention
Technical matters to be solved by this invention, is to provide a kind of child seat to absorb energy framework.At automobile generation head-on crash, under producing the effect of acceleration/accel, children and seat produce longitudinal travel, drive absorption energy framework absorption energy, with existing carry the child seat of safety strap coordinate the object reaching child protection.
Technical scheme of the present invention:
Construct a kind of child seat and absorb energy framework, it is characterized in that forming primarily of quadra, dead axle, front big envelope, extrusion head, cushion block, extruding plate, packing ring, sliding sleeve, seat board and rear big envelope.
Described quadra coordinates with adult seat to be installed.
Described extruding plate and packing ring be closed assembly some groups successively, is fitted in sliding sleeve with cushion block, and forward and backward big envelope seals sliding sleeve two ends and compresses cushion block, extruding plate, packing ring.Dead axle, through forward and backward big envelope and extrusion head, coordinates with forward and backward big envelope, extrusion head interporal lacuna, is arranged on sliding sleeve center, and fixedly mount with quadra.
Described sliding sleeve and seat board fixedly mount, and seat board coordinates fixing with the existing safety strap child seat that carries.
Absorb energy framework according to child seat provided by the invention, it is characterized in that, extrusion head outside diameter is greater than dead axle diameter, and with cushion block free-running fit, height is contour with cushion block.
Absorb energy framework according to child seat provided by the invention, it is characterized in that, extruding plate aperture is less than extrusion head outside diameter.
Absorb energy framework according to child seat provided by the invention, it is characterized in that, packing ring aperture is greater than extrusion head outside diameter, and thickness is greater than the height after the squeezed pressure head flange of extruding plate.
Absorb energy framework according to child seat provided by the invention, it is characterized in that, several the extruding plate thickness adjacent with extrusion head are greater than the thickness of other extruding plates.
Realize child seat of the present invention and absorb energy framework; produce the effect of acceleration/accel at automobile generation head-on crash under; the longitudinal travel that children and seat produce, drives and absorbs energy framework and absorb energy, with existing carry safety strap child seat coordinate the object reaching child protection.
Accompanying drawing explanation
Be illustrated as the structural representation that child seat of the present invention absorbs energy framework.
Detailed description of the invention
As shown in the figure, this is that a kind of child seat absorbs energy framework.Quadra 1 coordinates with adult seat to be installed, and extruding plate 6 and packing ring 7 successively closed assembly some groups and cushion block 5 are fitted in sliding sleeve 8.Front big envelope 3, rear big envelope 10, seal sliding sleeve 8 two ends and compress cushion block 5, extruding plate 6, packing ring 7.Dead axle 2, through front big envelope 3, rear big envelope 10 and extrusion head 4, with front big envelope 3, rear big envelope 10, extrusion head 4 free-running fit, is arranged on the center of sliding sleeve 8, and fixedly mounts with quadra 1.Sliding sleeve 8 and seat board 9 fixedly mount, and seat board 9 coordinates fixing with the existing safety strap child seat that carries.
Child seat of the present invention absorbs energy framework, coordinates and installs in use with the existing safety strap child seat that carries.When automobile generation head-on crash and high speed sudden stop, by the constraint of child seat belt, the impulsive force that children and child seat produce under acceleration/accel effect, drive seat board 9 and sliding sleeve 8 longitudinal travel, sliding sleeve 8, interior cushion block 5, extruding plate 6, packing ring 7 produce mutual motion with dead axle 2 and extrusion head 4.Extruding plate 6 is under the support of packing ring 7 is fixing, and squeezed pressure head 4 extrudes back aperture and is expanded into flange shape.Sliding sleeve 8 constantly moves forward, and causes extruding plate 6 below constantly to be extruded successively, and after causing again each extruding plate 6 to be above extruded, friction force mutual with extrusion head 4 superposes successively.After the length after some groups of extruding plates 6 are extruded exceedes the height of extrusion head 4, it continues squeese pressure that longitudinal travel produces and friction force, will remain on a more stable value in the scope of sliding sleeve 8 and dead axle 2.At this moment the distance that the energy absorbed and children and seat move forward, just alleviates the extent of injury of acceleration/accel to infant.
Meanwhile, the thickening of several group extruding plates 6 adjacent with extrusion head 4, be in order to prevent automobile slight impact and comparatively low speed brake under, the absorption energy motion of generation.In order to avoid impact is when high-speed crash and high speed sudden stop, the absorbent absorption maximum energy of device.
In addition, child seat of the present invention absorbs energy framework, also may be used for the absorption energy framework of adult seat.Meanwhile, after removal framework also improves, the absorption energy safety device bottom cage lifter can also be become.
