Abstract
The invention discloses an explosion shock wave protection device of a motor vehicle, which comprises an upper protection plate (1) and a lower protection plate (2) arranged in parallel, wherein a plurality of energy absorption mechanisms (3) used for absorbing and buffering an explosion shock wave are arranged between the upper protection plate (1) and the lower protection plate (2). The explosion shock wave protection device of the motor vehicle can improve the explosion shock wave protection capacity of the vehicle, and cannot reduce the maneuvering performance and the passing performance of the vehicle.
Description
Technical field
The invention belongs to motor vehicles protector technical field, particularly a kind of shock wave motor vehicles blast protection shock wave device that vehicle and occupant are damaged effectively can resisted land mine or improvised explosive blast and produce.
Background technology
In the war in Iraq and Afghanistan, the various haulage vehicles of the U.S. and allied forces thereof are often subject to the attack of land mine and improvised explosive devices (IED), cause the life of a large amount of battlefield personnel to be subject to serious threat, cause great personnel, property loss.West various countries are for international peace-keeping operations and the demand tackling day by day serious threat of terrorism challenge, from last century the nineties not just pay close attention to the anti-kinetic energy shell fragment of vehicle and land mine to the research of occupant's threat aspect, and formulated corresponding standard, as the STANAG4569 of NATO, the RSA-MIL-STD 1 etc. of the U.S..Lightning protection field at the bottom of the anti-kinetic energy shell fragment of car body and car, plentiful and substantial achievement in research has been obtained by development of new composite and country such as special car bottom structure, South Africa etc., and the product of this achievement of application has been put into Iraq and the use of Afghan battlefield, as the serial MRAP of RG 1, " poisonous snake " high motor-driven vehicle of OSHKOSH truck company production, G-Wagon280CDI lightweight armor patrol vehicle etc. of Benz Co.'s production of U.S. army.Make a general survey of this type of vehicle, car body and all have employed the composite with ballistic performance and the V-shape structure being beneficial to dispersion shock, but this V-shape structure sacrifices the minimum ground clearance of vehicle, what reduce vehicle passes through performance.
The armoring protection level of entirety of modern armed vehicle is more and more higher, can defend the threat of most of antivehicle mine or improvised explosive devices (IED), but show from the data that segregated area and peace-keeping operations obtain, antivehicle mine or improvised explosive thing and the injury caused is still in rising trend, this is because Tank and Armoured Vehicle is when being subject to such and attacking, a lot of casualty accident is not caused because plate armour punctures, but caused by by the detonation impact energy of the structure such as vehicle, seat to human body transmission.
Therefore, prior art Problems existing is: motor vehicles blast protection shock wave scarce capacity, security protection performance is inadequate.
Summary of the invention
The object of the present invention is to provide a kind of motor vehicles blast protection shock wave device, the blast protection shock wave ability of vehicle can be improved, do not reduce again the mobility of vehicle and pass through performance.
The technical solution realizing the object of the invention is: a kind of motor vehicles blast protection shock wave device, comprise the upper protective plate and lower protective plate that be arranged in parallel, on described, be provided with multiple energy absorber for absorbing, cushioning explosion wave between protective plate and lower protective plate.
The present invention compared with prior art, its remarkable advantage:
1, vehicle blast protection shock wave function is improved: the huge energy that blast produces effectively can be converted into the elastic potential energy of spring by the energy absorber be arranged between two pieces of protective plates; Meanwhile, two pieces of protective plates effectively can stop the kinetic energy shell fragment that blast produces, so the present invention can reduce the injury of exploding to vehicle and occupant greatly.
2, do not reduce the mobility of vehicle and pass through performance: the V-type plate foot guard mechanism that the present invention is different from the past, not sacrificing the minimum ground clearance of vehicle, substantially increase trafficability energy, and structure is simple, be easy to realize and install.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is motor vehicles blast protection shock wave device top view of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
In figure, protective plate on 1,2 times protective plates, 3 energy absorbers, 31 bolts, 32 nuts, spring card slot on 33,34 lower spring draw-in grooves, 35 springs, rubber blanket on 36,37 times rubber blankets.
Detailed description of the invention
As shown in Figure 1, motor vehicles blast protection shock wave device of the present invention, comprises the upper protective plate 1 and lower protective plate 2 that be arranged in parallel, on described, be provided with multiple energy absorber 3 for absorbing, cushioning explosion wave between protective plate 1 and lower protective plate 2.Described upper protective plate 1 can be also directly vehicle floor.
The huge energy that blast produces effectively can be converted into the elastic potential energy of spring by the energy absorber be arranged between two pieces of protective plates; Meanwhile, two pieces of protective plates effectively can stop the kinetic energy shell fragment that blast produces, so the present invention can reduce the injury of exploding to vehicle and occupant greatly.
And do not sacrifice the minimum ground clearance of vehicle, substantially increase trafficability energy, and structure is simple, is easy to realize and install.
Below all as shown in Figure 2.
Described energy absorber 3 comprises bolt 31, nut 32, upper spring card slot 33, lower spring draw-in groove 34 and spring 35, described bolt 31 is connected with nut 32 through after upper protective plate 1, upper spring card slot 33, spring 35, lower spring draw-in groove 34, lower protective plate 2 successively, be connected in aggregates by protective plate 1 with lower protective plate 2, the two ends of described spring 35 are separately fixed in spring card slot 33 and lower spring draw-in groove 34.
Bolt 31 not only plays the guide effect to spring 35, plays effect vehicle floor or upper protective plate 1 linked together with lower protective plate 2 simultaneously.
Upper spring card slot 33, lower spring draw-in groove 34 are welded on protective plate 1 and lower protective plate 2 respectively, and the two ends of spring 35 are separately fixed in the groove of spring card slot 33 and lower spring draw-in groove 34.Like this, when spring generation deformation, its two ends are still limited in groove and can not occurred level displacement.
As improvement, between the upper protective plate 1 and upper spring card slot 33 of described energy absorber 3, be also provided with rubber blanket 36.
As further improvement, between the lower spring draw-in groove 34 and lower protective plate 2 of described energy absorber 3, be also provided with lower rubber blanket 37.
Rubber blanket is damping original paper, can play endergonic effect, and effectively can alleviate the injury impacted and bring to protective plate.
Described spring 35 is metal spring.The spring of other identical performance can certainly be adopted.
