Abstract

This practicality proposes a kind of efficient bulletproof halmet, solves the problems, such as existing helmet bulletproof performance deficiency.It includes inner casing, compliant member, thin plate；The inner casing is connected with multiple compliant members by adhesive, is fixed on inner casing outer surface；Compliant member is connected with thin plate by adhesive, and compression occurs after being extruded by bullet for compliant member, and thin plate moves therewith so that bullet is changed into oblique penetration from positive penetration, and the motion of thin plate can absorb part bullet kinetic energy.This practicality is splashed by designing circular arc type thin plate bullet and sliding, by designing compressible flexible part and movable thin plate bullet " oblique penetration of going off course ", part bullet kinetic energy is absorbed by the motion of thin plate and the compression of compliant member, so as to weaken the Penetration Ability of bullet, the anti-bullet efficiency of the helmet is greatly improved.

Description

A kind of efficient bulletproof halmet

Technical field

This practicality is related to a kind of helmet, more particularly to a kind of efficient bulletproof halmet.

Background technology

The helmet is a kind of individual soldier protection harness for making head escape injury.Statistics shows, fragmentation and direct projection bullet The main reason for injury to combatant head is combat casualty, the probability fallen in battle far above other body parts injury. Therefore, bulletproof halmet is that combatant is most basic and most important protective gear.

The V50 values of existing military helmet are 630m/s, and anti-resilience energy power disclosure satisfy that battlefield individual soldier protection demand substantially.But It is that under Complex Battlefield Environments, the injury of fragmentation and direct projection bullet to combatant head closely is fatal, military helmet Low coverage ballistic performance need further to be improved.Therefore, it is highly desirable to develop a kind of efficient bulletproof halmet, disclosure satisfy that low coverage Individual soldier protection demand.

The content of the invention

This practicality proposes a kind of efficient bulletproof halmet, by designing circular arc type thin plate so that bullet, which is slided, to be splashed, and passes through design Compressible flexible part and movable thin plate cause bullet " oblique penetration of going off course ", pass through the motion of thin plate and the pressure of compliant member Compression deformation absorbs part bullet kinetic energy, so as to weaken the Penetration Ability of bullet, greatly improves the anti-bullet efficiency of the helmet, reduces fight Person head is hit by a bullet caused casualty rate.

Concrete technical scheme is as follows：

A kind of efficient bulletproof halmet, including inner casing, compliant member, thin plate；The inner casing uses high-strength lightweight composite material It is made, wraps up the whole head of combatant；The compliant member uses foamed material, column is shaped as, after being extruded by bullet Generation compression, part bullet kinetic energy is absorbed, whole inner casing outer surface is equidistantly uniformly distributed between the compliant member；Institute State thin plate to be made of the composite of high-strength light, its surface configuration is designed as circular arc type curved surface so that bullet connects in collision Cunning occurs when touching its surface to splash；The inner casing is connected with multiple compliant members by adhesive, is fixed on inner casing outer surface；It is described Compliant member is connected with the thin plate by adhesive, and 5mm is smaller than between the thin plate on adjacent flexible part；Flexible part Compression occurs after being extruded by bullet for part, and thin plate moves therewith so that bullet is changed into oblique penetration, the motion of thin plate from positive penetration Part bullet kinetic energy, bumper and absorbing shock can be absorbed.

Different applicable cases are further considered, the bulletproof halmet also includes covering, and the covering uses cotton Colour camoufague cloth, cover on thin plate, cover the whole helmet, do not influence the motion of thin plate.

The beneficial effect obtained using this practicality

Compared with prior art, its advantage is for this practicality：

1) efficiently for bulletproof halmet by increasing the thin multilayer composite material thin plate of attached high-strength light, its surface is designed as circular arc type Curved surface so that " cunning is splashed " is produced when bullet contacts its surface, can not effective penetration.

2) it is efficiently shellproof by setting up compressible flexible material after thin multilayer composite material thin plate so that bullet occurs inclined Boat, is changed into " oblique penetration " from " positive penetration ", effectively weakens the Penetration Ability of bullet.

3) efficiently bulletproof halmet passes through the yaw motion of thin plate and the part of the compression absorption bullet of flexible material is moved Energy, further weaken the Penetration Ability of bullet.

This practicality is the improvement to the shellproof buffer structure of the helmet, is not related to the specific configuration of the helmet.Therefore this practicality can be with The helmet applied to different designs configuration.

Brief description of the drawings

In order to illustrate more clearly of in this practical embodiment or technical scheme of the prior art, below will to embodiment or The required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only Some embodiments of this practicality, on the premise of not paying creative work, can be with root for ordinary skill Other accompanying drawings are obtained according to these accompanying drawings.

Embodiment

To make this practical purpose, technical scheme and advantage clearer, below in conjunction with accompanying drawing to this practical embodiment party Formula is described in further detail.

Reference picture 1 is the composition schematic diagram of efficient bulletproof halmet.A kind of efficient bulletproof halmet, including inner casing 1, compliant member 2nd, thin plate 3,

The outer surface of the inner casing 1 is connected with multiple compliant members 2, and the compliant member 2 is connected with thin plate 3, described thin Plate 3 is arc-shaped surface.

Further：The inner casing 1 is made of Kevlar fibre reinforced composites, wraps up the whole head of combatant Portion；

Further：Thin plate 3 is made of the 3K carbon fibre materials of high-strength light, thickness 20mm, with reference to its surface of figure 3 Shape is designed as circular arc type curved surface so that bullet occurs " cunning is splashed " in making contact thin sheet surface；Can not effective penetration.

Further：The compliant member 2 is made of soft polyurethane foam material, is shaped as column, thickness is 30mm, whole inner casing outer surface, compliant member after being extruded with reference to figure 4 by bullet are equidistantly uniformly distributed between the compliant member 2 occur compression, absorb part bullet kinetic energy；And thin plate 3 moves therewith so that bullet is changed into oblique penetration from positive penetration, thin The motion of plate 3 can absorb part bullet kinetic energy, greatly improve the anti-bullet efficiency of the helmet.

Further：The inner casing 1 is connected with multiple compliant members 2 by Araldite-2015 type adhesives, is fixed on The outer surface of inner casing 1；

Further：The compliant member 2 leads to Araldite-2015 type adhesives with the thin plate 3 and connected, adjacent flexible 5mm is smaller than between thin plate on part；

Further：Reference picture 2, it is contemplated that different applicable cases, the bulletproof halmet include covering, and the covering is adopted With cotton colour camoufague cloth, cover on thin plate, cover the whole helmet, do not influence the motion of thin plate.

Further：The covering lower end can be fixed on inner casing lower end.

This practical preferred embodiment is the foregoing is only, it is all in this practical essence not to limit this practicality God any modification, equivalent substitution and improvements done etc., should be included within this practical protection domain with principle.
