Description

Digitize electromagnetic pulse formula active cervical vertebra protective device

Technical field

The utility model is related to high speed carrier safety protection structure, especially a kind of effectively protection cervical vertebra, the injured journey of reduction The digitlization electromagnetic pulse formula active cervical vertebra protective device of degree, reduction traffic mortality.

Background technology

With the expansion in mankind's activity space, the pursuit to speed and traffic causes various high-speed motion carriers, such as vapour Car, train, high speed naval vessels, aircraft carrier-based aircraft etc., it is fast-developing.Thus huge negative effect is also generated.The whole world Every year because traffic accident causes about 1,200,000 people dead, direct economy damages 518,000,000,000 dollars., China's mechanical transport thing in 2004 Therefore sum is 567753, cause 99217 people dead, 451810 people are injured, 27.7 hundred million yuan of direct property loss.In road collision In accident, death by accident 73% is preceding collision, and position 78.2% of causing injury concentrates on neck, is most especially with stretching-flexing damage See.

In preceding collision process, great change occurs for the speed of high-speed motion carrier, and the incidence of occupant is due to used Property effect, have larger compound movement relative to chest, under different motion modes, the structure of neck different parts reaches it The limit is born, so as to cause different degrees of damage, is mainly had：

（1）Shear property model.During head-on crash, when retarded motion occurs for chest, head is continued to protect by inertia force Linear uniform motion is held, chest, which is received, carries out retarded motion after belt force.Head applies under inertia force effect to neck One pulling force forward, chest applies a pulling force backward in the presence of safety belt to neck, when pulling force reaches suffered by neck During to the limit, atlanto occipital joint will be separated, it means that ligament and other soft tissues are torn.Multiply in this kind of collision accident Member's neck can cause the injuries such as joint separation and fracture due to having been exceeded tolerance limit by shearing force.

（2）Tensile damage.During head-on crash, axial compressive force is not present, and neck stress is mainly axial tension Power.Anteflexion deformation occurs for neck after an impact, and cervical vertebra is upright, and Cervical vertebra starts elongation, gradually causes upper cervical spine to extend, whole neck Vertebra is into " S " type curve.

（3）Bending Damage.Bending Damage shows as positive bending and lateral thrust.Forward direction bending shows as working as collision Occiput drives neck to front reduction gear and flutters motion downwards.When neck institute bending moment has reached cervical vertebra can be caused to take off after tenability limit Mortar, pulled muscle etc. are injured.The active force or inertia force that lateral thrust shows as acting on head depart significantly from center arrow Shape face, neck will be by the lateral thrust in company with axial load and shearing force.The impaired performance of this kind of bending is centrum Lateral wedge fracture and the fracture at vertebra side rear portion.

As can be seen here, the injury caused by preventing head-on crash is mostly important.Currently for the safeguard procedures of head-on crash Predominantly safety belt and air bag, but the two is respectively provided with deficiency.

Safety belt.Safety belt prevents that thorax abdomen from colliding by limiting trunk reach, can effectively reduce the death rate.But Also trunk reach is limited in preceding collision just because of safety belt, and head keeps reach due to the effect of inertia force, the two Relative displacement cause the generation of neck injury.

Air bag.Air bag is more and more applied on automobile as important passive security measure.It is acted on Principle is to start air bag ignition device by the acceleration change of paratonic movement carrier, and gas is filled by combusting solids fuels Capsule.Occurring when head-on crash, upper body quickly move forward and balloon contacts and buffering percussive force, it is to avoid it is by steering wheel, preceding wind The injury of the rigid part such as gear.But it is due to expensive, common vehicle is difficult to install multiple air bags and play perfect to occupant Protective effect.And typically air bag is not installed on the quick motion carrier such as train, quick naval vessels, aircraft carrier.Separately Outside, gasbag pressure is huge, and the duration of ignition has delay, and incidence damage is caused under the anxious deceleration situations such as preceding collision in contact gas Capsule has occurred and that, or occupant, and especially teenage occupant is injured by air bag impact.

A kind of cervical vertebra protective device for being exclusively used in high speed carrier of design is necessary.
