Abstract

A bullet-proof and explosion-proof garment has two schemes for realizing bullet-proof and explosion-proof functions. The proposal is that the elastic and viscous semi-solid substance is forced to extrude and overflow to the periphery, and the kinetic energy of the bullet is absorbed by the overflow process. And the semi-solid viscous substance which has certain elasticity and toughness and can deform in shape and overflow outwards when being extruded is replaced by springs with different elasticity and lengths to support the steel plate C, so that the kinetic energy of the bullet is absorbed by different springs in a grading manner.

Description

Bulletproof and explosion-proof garment

Technical Field

The utility model relates to a bulletproof material different from the previous bulletproof method, in particular to bulletproof and explosion-proof clothes.

Background

Since the time of mankind, the struggle between spears and shields has been long, but as mankind enters the age of new firearms, shields are actually gradually downwind, and on the one hand, materials that are both light and hard enough are developed more and more limitedly; on the other hand, the impact force of explosion is larger and larger, and the penetration force is stronger and stronger due to the autorotation of the bullet head, so that the bullet is inexhaustible. Moreover, the armor which is thicker and heavier can never flexibly and effectively protect the movable joint part of the human body. The inventor submits application (application number: 201921709979.4) of a practical model of 'bulletproof and explosion-proof material under a new concept' on 2019, 10 and 11, and on the basis of the scheme, the utility model provides two other different schemes.

Disclosure of Invention

In order to resist the bullet or shrapnel with stronger destructive power and killing power, the invention adopts a completely different concept from the previous various protections, namely, the original overall protection of hard-on-hard is changed into the step-by-step differentiation absorption of the kinetic energy of the bullet or shrapnel. The invention relates to two other schemes aiming at absorbing the kinetic energy of a bullet in stages on the basis of 'a bulletproof and explosion-proof material under a new concept' submitted in 2019, 10, 11 and 11. Scheme I referring to scheme I in figure 6 of the attached drawings, each single protection sheet consists of 5 parts, namely, a protection film layer for preventing semi-liquid viscose from overflowing, B an outermost layer of strong-viscosity colloid substance, C a middle high-strength thick steel plate, D a semi-solid-state viscosity substance with certain elasticity and toughness and capable of deforming in shape and overflowing outwards when being extruded, and E an innermost layer of high-strength thin steel plate. The elastic and viscous semi-solid substance is forced to extrude and overflow to the periphery, and the kinetic energy of the bullet is absorbed by the overflow process. Scheme two, the legend of which refers to scheme two in figure 6 of the specification, is that springs with different elasticity and length are used for replacing semi-solid viscous substances which have certain elasticity and toughness in the middle inner layer of the scheme one, can deform in shape when being extruded and overflow outwards, the middle high-strength thick steel plate C is supported, and after the middle high-strength thick steel plate C is stressed, the spring which extrudes the longest spring, the thinnest spring and the spring with the minimum elasticity retreats; with the continuous retreat of the middle high-strength thick steel plate C, the middle high-strength thick steel plate C is supported by a slightly thick spring with a secondary length and a slightly strong elasticity; and then the middle high-strength thick steel plate C continuously retreats, and finally the shortest, thickest and strongest-elasticity spring starts to contact and support the middle high-strength thick steel plate C. This grading uses different springs to absorb the kinetic energy of the bullet.

The specific implementation scheme is as follows:

in order to achieve the above purpose, the utility model adopts the following scheme:

fig. 1 and 2 are schematic front and back views of a body protective garment made of a single sheet of protective material for protection against bullets and explosions. The protective material is reduced and connected in a scaly way, so that the protective material not only completely covers the joint moving part of a human body, but also can increase air permeability and improve comfort. The connection mode is bonding, namely one of the three adjacent pieces of material is overlapped and bonded, and the connection mode is the same as that of ancient armor, but the connection mode is changed into bonding mode from nailing together, because nails and rivets can change the internal structure of the single piece of protective sheet, and the protective capability is influenced. According to the protection level and the requirements of key parts of a human body, the area of a single piece of protection material is increased as much as possible on the premise of not influencing joint movement, the larger the area of the single piece is, the smaller the pressure intensity under the same impact force is, and the larger the protection capability is, so that the single piece area is recommended to be not less than 10cm and 10cm, and the specific application design needs to be according to application 1, namely the possible danger, the larger the protection capability needs, and 2, according to different parts of the human body, important positions of the chest, the abdomen, the back and the like of the human body are recommended to be maximized as much as possible.

FIG. 3 is a schematic front and back view of a single guard plate.

Fig. 4 a is a side anatomical view of a single guard plate of scenario one. Each single piece of protective material is divided into A, B, C, D, E parts, A is a protective film layer for preventing semi-liquid viscose from overflowing; b is an outer layer strong adhesive colloid substance (hereinafter referred to as a strong adhesive substance), which mainly has the functions of adhering the elastic sheet to absorb a part of forward impact kinetic energy, reducing the spinning of the bullet to reduce the penetrating power of the bullet, and adhering the bullet when the bullet contacts the middle thick steel plate to avoid the rebound of the bullet; and fourthly, the action time of the bullet head on the impact force of the middle high-strength thick steel plate is prolonged. C is a middle high-strength thick steel plate; d is semisolid viscous substance (hereinafter referred to as strong-elasticity semisolid overflowing substance) with certain elasticity and toughness at the inner layer and capable of deforming and overflowing outwards when being extruded; e is an innermost high-strength steel sheet. Each sheet of such protective material is thick in the middle and thin at the periphery.

And B is a schematic diagram of the bullet in flight in the first scheme, wherein the bullet rotates forwards to approach the protective sheet.

Fig. 5 is a schematic diagram of the scheme that the bullet head which rotates at high speed and moves forwards hits the outermost adhesive layer. When the bullet hits the protective material, firstly, the outermost protective film layer and the semi-liquid viscose with extremely strong viscosity are hit, the viscose can absorb a part of forward kinetic energy of the bullet by utilizing the viscosity of the viscose, and more importantly, the bullet cluster can be enclosed by a wrapping mode to absorb the kinetic energy of the bullet in high-speed rotation, namely, the rotation speed of the bullet is reduced to the maximum extent, and the penetrability of the bullet is greatly weakened. In fact, at this stage, the self-rotation energy and the forward impact kinetic energy of the bullet are partially absorbed by the semi-liquid adhesive, and more importantly, the self-rotation energy and the forward impact kinetic energy prolong the impact time of the bullet on the first protective steel plate. When the bullet enters the adhesive area, the forward impact force of the bullet head starts to pass through the extruded adhesive and transmits the forward impact kinetic energy until the bullet head directly contacts the first layer of steel plate, which is completely different from the situation that the bullet head directly hits the steel plate, because the action time of the steel plate affected by the impact force of the bullet is prolonged, according to F & ltm & gtv/t (F is the impact force, m is the mass, v is the velocity, and t is the impact time), it can be seen that F is inversely proportional to t, that is, the impact force of the steel plate on a unit area is reduced, so that the possibility of the steel plate being punctured by the bullet is low.

Scheme one of fig. 6: the schematic diagram of the first embodiment is that the elastic and tough semisolid viscous substance in the inner layer of the solution D overflows when being extruded. The middle high-strength thick steel plate C is impacted by the bullet heads, so that the steel plate integrally extrudes the elastic semi-solid viscous substance, and the elastic semi-solid viscous substance is backward 'yielded' when being extruded by the steel plate due to the elasticity and toughness of the layer of substance, so that the layer of substance begins to be extruded and yielded when the forward impact force of the bullet heads begins to act on the middle high-strength thick steel plate C. And because the periphery of the layer of material is not provided with a sealing frame, the material is extruded and then overflows outwards to deform, the whole middle high-strength thick steel plate C is retreated along with the outward overflow of the semi-solid viscous material D with certain elasticity and toughness behind the thick steel plate C, the larger the impact force is, the more the viscous material overflows until the forward impact kinetic energy of the bullet head is completely absorbed, and the breakdown is avoided. On one hand, after the steel plate is subjected to the impact action force of the bullet, the whole steel plate is retreated, and the time of the impact force of the bullet on the layer of steel plate is prolonged again according to F ═ m v/t, so that the impact force of the bullet on the steel plate is reduced; on the other hand, the process of overflowing the elastic semi-solid viscous substance in the layer can greatly absorb the impact kinetic energy of the bullet on the human body. Because the damage of the bullet to the human body is divided into two categories: the first is the penetration of the bullet to destroy the tissue of the human body, and the second is the kinetic energy of the impact. Besides the damage of the bullet penetrating through the human body, the bullet has impact force on the human body, the damage of the impact force cannot be reduced by the hard collision of the traditional armor protection, so the human body cannot be pushed down by the bullet under the protection. In the design, after the semi-solid viscous substance D with certain elasticity and toughness is extruded and deformed by the middle high-strength thick steel plate C, the edge of the protective material layer is open, and no shell exists around the semi-solid viscous substance D, so that the colloid can be extruded out, and the extruded process is the process of absorbing forward impact kinetic energy of a bullet to a human body, so that the damage of the bullet and the impact on the human body can be reduced in the mode. When the kinetic energy of the bullet is completely absorbed, the substance which is spilled over the edge will return to the original position with the disappearance of the impact force and be ready to resist the impact of the next bullet, so that the bulletproof material is not disposable and can be used repeatedly.

Scheme two of fig. 6: in the second scheme, the inner layer is a spring schematic diagram with elasticity and toughness. When the middle high-strength thick steel plate C is impacted by a bullet, the middle high-strength thick steel plate C is extruded to the inner layer, the inner layer is sequentially arranged by three springs with different strengths, thicknesses and lengths, and firstly, the springs with the first, thin, long and loose inner layers are extruded and then receded; when the pressure is stronger and stronger, the middle high-strength steel plate C continues to be extruded backwards, and then thicker, shorter and tighter springs are extruded and receded; when the middle high-strength steel plate C continues to extrude backwards, the inner layer is provided with a strong spring with a large, short and tight structure to resist the extrusion of the middle high-strength steel plate C and further absorb the impact kinetic energy of bullets, thereby playing a role of defense. When the impact kinetic energy of the bullet is completely absorbed, all the springs are reset to prepare for the impact of the next bullet. The design that the grading spring and the steel plate are matched to gradually absorb the energy of the bullet is the key point of the scheme. If the absorption is not graded and gradual, the steel plate is likely to be hit by a bullet in the process, so that the hardness of the steel plate, the strength of the spring and the grading layer number must be matched with factors of the weight of the bulletproof clothes made of the material, which can be adapted by people, in practical application, and no specific experimental data is provided in the design.

FIG. 8: the schematic diagram of the flying bullet in the second scheme that the steel plate spring is completely extruded when the flying bullet hits. When the protection sheet enters the outermost layer of strong viscous substance and reaches the thick steel plate during bullet impact, the three-stage spring is extruded and retreats backwards in sequence.
