Description

A kind of body structure of bulletproof car

Technical field

The utility model belongs to field of automobile, specially refers to the body structure of bullet-proof car.

Background technology

Bullet-proof car is owing to its ball proof special purpose, though according to the shellproof grade of difference, have any different in shellproof position, and protection personal security by bus is the most basic, preferentially will consider ball proof tightness when this requires design.And ball proof tightness contradicts with the automobile anti-corrosion treatment, the anticorrosion main employing electrophoresis of automotive interior is realized at present, the structure of bullet-proof car, particularly generally comparatively sealing of hollow cylinder places such as its A post, B post, C post and back timber, this has just hindered the speed that electrophoresis liquid enters automotive interior, thereby influences the thorough rate of electrophoresis of bullet-proof car, if arbitrarily open liquid-leaking nozzle, though can accelerate the speed that electrophoresis liquid enters automotive interior, improve the thorough rate of electrophoresis, can influence bulletproof effect.

The utility model content

The purpose of this utility model is that proposition is a kind of when guaranteeing bulletproof effect, can effectively improve the body structure of the bullet-proof car of the thorough rate of electrophoresis.

The key of the body structure of bullet-proof car of the present utility model is to be provided with in its hollow cylinder auxiliary armour plate, auxiliary armour plate center over against the cylinder steel plate have circular liquid-leaking nozzle, the both sides and the cylinder inside face of the Width of auxiliary armour plate are welded as a whole, the length of auxiliary armour plate Wherein

Be the liquid-leaking nozzle diameter,

The minimum diameter of the bullet that can prevent for bullet-proof car,

Be auxiliary armour plate and its distance over against the cylinder steel plate.

Liquid-leaking nozzle can make electrophoresis liquid enter in the hollow cylinder, the inside face of hollow cylinder is carried out anti-corrosion treatment, and the right opposite of liquid-leaking nozzle is provided with auxiliary armour plate, can avoid bullet by in the liquid-leaking nozzle into the car, guarantee bulletproof effect.For saving in material and alleviate complete vehicle weight, the length of auxiliary armour plate can not be long, the length computation principle of auxiliary armour plate as shown in Figure 2, the spacing of the armour plate (3) on auxiliary armour plate (1) and hollow cylinder surface The diameter of the liquid-leaking nozzle of being opened on the armour plate on hollow cylinder surface (3) (5) Be known,

Be the length of auxiliary armour plate (1), determine that according to the shellproof specification of bullet-proof car the minimum diameter of the bullet (7) that bullet-proof car can be prevented also is known, therefore just calculate the length dimension of auxiliary armour plate (1) as long as determine the incident angle of bullet (7)

When bullet is in liquid-leaking nozzle (5) directive car, as long as right-angled triangle △ ABC

Edge lengths is less than the bullet diameter, and bullet will be stopped and can't enter in the car by liquid-leaking nozzle (5) by armour plate on hollow cylinder surface (3) or auxiliary armour plate (1), promptly reaches bulletproof effect.

Be calculated as follows according to trigonometric function:

$\mathrm{Tan}\&angle;\mathrm{ABC}=\frac{\stackrel{\&OverBar;}{\mathrm{AC}}}{\stackrel{\&OverBar;}{\mathrm{CB}}},$ $\mathrm{Tan}\&angle;\mathrm{BED}=\frac{\stackrel{\&OverBar;}{\mathrm{BD}}}{\stackrel{\&OverBar;}{\mathrm{ED}}},$ ∠ABC＝∠BED；

Thus: $\stackrel{\&OverBar;}{\mathrm{ED}}=\frac{\stackrel{\&OverBar;}{\mathrm{CB}}}{\stackrel{\&OverBar;}{\mathrm{AC}}}\&CenterDot;\stackrel{\&OverBar;}{\mathrm{BD}};$

Again because $\stackrel{\&OverBar;}{\mathrm{AB}}=\stackrel{\&OverBar;}{\mathrm{GD}},$ $\stackrel{\&OverBar;}{\mathrm{ED}}=\stackrel{\&OverBar;}{\mathrm{EG}}+\stackrel{\&OverBar;}{\mathrm{GD}},$ $\stackrel{\&OverBar;}{\mathrm{EG}}=\stackrel{\&OverBar;}{\mathrm{DF}},$ $\stackrel{\&OverBar;}{\mathrm{CB}}=\sqrt{{\stackrel{\&OverBar;}{\mathrm{AB}}}^2-{\stackrel{\&OverBar;}{\mathrm{AC}}}^2};$

So can get: $\stackrel{\&OverBar;}{\mathrm{EF}}=\stackrel{\&OverBar;}{\mathrm{ED}}+\stackrel{\&OverBar;}{\mathrm{DF}}$

$=2\&CenterDot;\stackrel{\&OverBar;}{\mathrm{ED}}-\stackrel{\&OverBar;}{\mathrm{AB}}$

$=2\&CenterDot;\frac{\stackrel{\&OverBar;}{\mathrm{CB}}}{\stackrel{\&OverBar;}{\mathrm{AC}}}\&CenterDot;\stackrel{\&OverBar;}{\mathrm{BD}}-\stackrel{\&OverBar;}{\mathrm{AB}}$

$=2\&CenterDot;\sqrt{{\stackrel{\&OverBar;}{\mathrm{AB}}}^2-{\stackrel{\&OverBar;}{\mathrm{AC}}}^2}\&CenterDot;\frac{\stackrel{\&OverBar;}{\mathrm{BD}}}{\stackrel{\&OverBar;}{\mathrm{AC}}}-\stackrel{\&OverBar;}{\mathrm{AB}}$

From the above, as long as will assist the length of armour plate (1) $\stackrel{\&OverBar;}{\mathrm{EF}}\&GreaterEqual;2\&CenterDot;\sqrt{{\stackrel{\&OverBar;}{\mathrm{AB}}}^2-{\stackrel{\&OverBar;}{\mathrm{AC}}}^2}\&CenterDot;\frac{\stackrel{\&OverBar;}{\mathrm{BD}}}{\stackrel{\&OverBar;}{\mathrm{AC}}}-\stackrel{\&OverBar;}{\mathrm{AB}},$ Just can prevent that bullet from passing through liquid-leaking nozzle (5) into the car.

For accelerating the speed that electrophoresis liquid enters automotive interior, described auxiliary armour plate over against both sides cylinder steel plate all have liquid-leaking nozzle, like this when electrophoresis, electrophoresis liquid can enter in the hollow cylinder by the liquid-leaking nozzle of both sides, and auxiliary armour plate can be avoided the liquid-leaking nozzle of bullet by any side into the car.

The diameter of the hollow cylinder of bullet-proof car liquid-leaking nozzle of a side outside car is less than or equal to the diameter of hollow cylinder liquid-leaking nozzle of a side in car, can improve the speed that electrophoresis liquid enters automotive interior when guaranteeing bulletproof effect like this.Because bullet is all outside car in the directive car, so as long as the diameter of the liquid-leaking nozzle of the outer side of car is enough little, bullet just can't be by liquid-leaking nozzle into the car.

On the radial section of hollow cylinder, auxiliary armour plate is divided into sectional area two zones about equally with hollow cylinder, to reach best leakage effect.

The hollow cylinder of described bullet-proof car comprises A post, B post, C post and back timber at least, and certainly, the liquid-leaking nozzle of all the other positions also can be according to above-mentioned principle setting.

The body structure of bullet-proof car of the present utility model by the design of change ballistic structure, has improved the thorough rate of vehicle body electrophoresis, thereby has improved the corrosion resistance of car load under the prerequisite that does not influence bulletproof effect.
