Abstract

The zero-weight-gain bulletproof upgrade of the automobile comprises zero-weight-gain bulletproof upgrade parts and an installation technology. Because the traditional automobile safety upgrading, particularly the safety upgrading of the bulletproof level, usually means adding weight type strength materials and parts, the weight of the upgraded automobile is greatly increased, the maneuverability of the automobile is seriously influenced, and the automobile is further influenced to break away from dangerous situations in time. The zero-weight-gain safe upgrade is realized by using various light-weight high-strength materials, improving the original parts of the automobile by reducing weight, thinning/deleting and the like, making overall planning on the local stress and deformation response of the automobile body from the perspective of the whole structure, and obtaining the protection effect of the whole automobile bulletproof at the cost of extremely slight weight gain of dozens of kilograms and even zero weight gain. The automobile body shell upgraded by the zero-weight-gain bulletproof technology has the anti-rollover deformation/anti-collision deformation strength which is improved by several times or even several tens of times, and can effectively relieve the injury of personnel and the damage of vehicles in accidents.

Description

Zero weight gain ballistic upgrade for automobiles

Technical Field

The invention relates to a safety upgrading technology of an automobile, in particular to a part kit and an installation technology which can prevent the automobile from rolling deformation, collision deformation and terrorist attack explosion fragmentation in severe accidents and aim at the gunshot of personnel in the automobile.

Background

The potential safety hazards of automobiles in accidents such as collision, rolling and the like and in man-made violence infringement such as gunshot explosion and the like are concentrated on the deficiency of the overall strength of the automobiles. The lack of overall strength is actually due to the lack of strength in several core components and locations. The key weak items are strengthened, and the problem of the overall mechanical strength of the automobile is solved.

In the standard design of the traditional automobile front windshield glass, in order to relieve the daily accidents that the probability of sudden braking of a vehicle, rear-end collision with a front automobile and the like is high, the head of a person is injured when the head of the person collides with the front windshield glass, the front windshield glass is required to be broken to absorb impact energy when being impacted by standards, and the situation that the impact energy is concentrated on the head of the person to injure the person is avoided. Because of the structural symmetry of traditional preceding windscreen, when bumping glass from the inboard very easily, just can't let glass have higher intensity from the outside yet and thus resist splash and do not take place to advance to split yet, can't realize higher anti penetration strength that faces on yet.

The traditional automobile side rear windshield technology still uses the relevant standards of European Community in 1970 s in terms of mechanical and mechanical properties, and the traditional side rear windshield with common use is generated by air-cooled tempering through 3-5mm single-piece float glass. The impact resistance index and the penetration resistance index of the existing standard are obviously lower than the actual requirements: when the vehicle overturns and rolls, the side rear windshield in the window frame often collapses in the twinkling of an eye in advance, so that the window frame loses support, and the rectangular window frame at the moment is easy to deform under the impact of collision and rolling, and the deformation of the rectangular window frame can undoubtedly cause direct injury to personnel in the vehicle.

When the glass in the automobile window frame does not collapse and maintains the original rigidity in the process of overturning and rolling of the automobile, the effective support can be generated on the window frame undoubtedly. At the moment of impact, once the rigidity of the vehicle is higher than that of the contacted object, the deformation is concentrated on the opposite side, and the vehicle collision contact part is not deformed obviously.

When the front windshield glass and the side window glass are designed to be in an asymmetric structure, the difference between the impact moments of the two surfaces of the glass is generated by utilizing the lever principle, and the internal and external difference of the mechanical properties of the front windshield glass and the side windshield glass can be realized.

The polyester safety lamination is pasted on the inner sides of the super front-grade glass and the side rear window explosion-proof glass, the glass is endowed with higher internal tensile stress, namely bending strength, from the inner side by utilizing extremely high tensile strength and bonding strength, and the glass is not cracked when being impacted by external splashes due to the higher stress value achieved by ion replacement of the outer surface.

When the glass is impacted from the inner side, the polyester safety lamination is firstly contacted, and the safety lamination which has the function of a moment pivot like the inner side is not arranged on the outer surface of the glass, so that the human head model test index of the front stop which cracks once the glass is collided with a piece of common glass can be completely met. And the safety lamination separates the head from the glass, so that the head cannot be scratched even if the glass is cracked.

The one-way protection function can also expand the front windshield into an escape passage. Because the traditional front windshield is of a sandwich structure, once the head of a person passes through the shoulders of the glass and cannot pass through the shoulders of the glass, a dangerous 'neck' situation can be formed, and therefore the automobile front windshield is not an originally designed escape channel. However, due to the structure of the super front windshield, the inner side of the super front windshield has the tough polyester safety lamination, so that people in the automobile cannot be scratched by the glass no matter using instruments or colliding the front windshield with bodies, and on the contrary, due to the protection of the safety lamination, the people in the automobile can easily take off the front windshield in a pedal mode, so that the people can escape from the front windshield from the inside;

according to the requirement, the strength of the super front-grade glass can reach the bulletproof level of military police, and the biggest bright point is the one-way bulletproof and counterattack performance of the front-grade glass. Namely, the shooting from the outside to the inside can be effectively prevented, and the shooting can be effectively carried out from the inside to the outside. The principle is the same as the above-mentioned penetration resistance, a polyester foil with a thickness of less than 1mm is in any case not capable of providing an effective barrier to the impact of bullets with extremely high impact pressure. When the shooting is counterstruck from the inside to the outside, the trajectory does not deflect obviously, and the bullet speed does not reduce obviously.

The automobile is easy to strongly deform in accidents such as collision and the like, and further personal injury in the automobile is caused. The root of the method is that the parts such as the car body, the car door and the like are made of steel plates with the thickness of less than 1mm, and the impact strength and the deformation strength are very low. When two objects collide with each other, if one of the objects is deformed and collapsed first due to insufficient strength, the impact energy of the collision is absorbed by the first deformed object, and the other object is not deformed. Therefore, the deformation resistance of the vehicle body and the vehicle door is improved, and the vehicle door has a direct corresponding relation for protecting the personal safety of personnel in the vehicle.

The coating is sprayed to the inner side of an outer skin steel plate and the inner side of an inner lining steel plate of the vehicle body from a high polyester liquid tank with more than two components, and functional attachments are generated in an AB material reaction mode and attached to the surfaces of the steel plates; the reinforced coating is composed of high polymer resin, and the components contain polyurethane; the coating has high temperature resistance, flame retardance, explosion prevention, noise reduction and bulletproof functions when the thickness is 0.3-1.5mm and the components are different;

in the traditional automobile manufacturing link, strength improvement on the parts such as doors and the like is not required due to the requirement of weight reduction, and the ultra-high molecular weight energy-absorbing fiber lining plate for the automobile body lining adopts nonmetallic ultra-high molecular weight polyethylene and aramid fiber materials, so that the weight of the plate is far lower than that of a steel plate with the same thickness and strength.

When the car body lining ultra-high molecular weight energy-absorbing fiber lining plate is pasted along the whole area of the car door and the car body outline, a composite structure of metal-high polymer material is formed, and the hardness and the rigidity of the metal and the toughness strength of the high polymer material are combined together to form an effective shock-resistant combination.

Professional live-fire attacks, which may be fired at the rear seat VIP using the so-called 45 degree angle of the a-pillar, occur in 5% of the incidence. Therefore, the bulletproof reconstruction of the A column is also indispensable, the ultra-narrow and trapezoidal grooves which are generated by impregnating the modified aramid fiber lining strips with the reinforced resin spraying coating are embedded in the lining of the A column to form the A column sniping-proof ultra-high molecular weight energy-absorbing fiber lining strips, and the bulletproof grade is different from 3mm to 15 mm.

The ultrathin explosion-proof and collision-proof chassis is sprayed with flexible armor, generally generated with the thickness of 1.0-3.0mm, corresponds to the curvature and the whole area of the chassis of the vehicle, is favorable for protection and heat dissipation and is generated in a spraying mode;

the metal gasket sheet at the groove bottom of the wheel rim groove of the vehicle anti-tire-burst overturning wheel hub and the tire anti-burst spraying are enhanced, the groove bottom of the wheel rim groove is sunken and sealed from the surface of the wheel rim through an alloy steel sheet, so that the tire can not be screwed out through the groove bottom and is tightly attached to the wheel hub, the tire is kept on the wheel hub for a long time, and the vehicle is ensured to normally run at a certain speed without overturning; before or after the tyre is installed on the wheel hub, the reinforcing paint is sprayed on the outer part along the surface, so that the penetration of explosion shock waves, explosion splashers and small fragments can be resisted.
