Technical field
The present invention relates to and belong to armored motor vehicles preventer technical field, the motor vehicles blast protection shock wave floating floor structure that particularly occupant is damaged by a kind of shock wave that can be effective against Rhizoma Anemones flaccidae or improvised explosive blast generation.
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 Rhizoma Anemones flaccidae and the attack of improvised explosive devices (IED), cause that the life of a large amount of battlefield personnel is subject to serious threat, cause great personnel, property loss. The demand that west various countries challenge for the threat of terrorism that international peace-keeping operations and reply are day by day serious, do not begin to pay close attention to the anti-kinetic energy shell fragment of vehicle and the Rhizoma Anemones flaccidae research to occupant's threat aspect from the nineties in last century, and formulated corresponding standard, such as the RSA-MIL-STD-37 etc. of the STANAG4569 of NATO, the U.S.. In the anti-kinetic energy shell fragment of car body and underbody lightning protection field, by development of new composite and special underbody structure, South Africa etc., country has been obtained for plentiful and substantial achievement in research, and the product applying this achievement has been put into Iraq and Afghanistan battlefield uses, the G-Wagon280CDI lightweight armor patrol vehicle etc. that " poisonous snake " high motor-driven part vehicle of producing such as the RG-33 series MRAP of U.S. army, OSHKOSH truck company, Benz Co. produce. Make a general survey of this type of vehicle, car body all have employed the composite with ballistic performance and be beneficial to the V-shape structure of dispersion shock, although this V-shape structure disperses explosion wave, but still some impact can act on vehicle floor, member is caused certain damage.
The overall armoring protection level of modern armed vehicle is more and more higher, most of antivehicle mine or the threat of improvised explosive devices (IED) can be defendd, but the data obtained from segregated area and peace-keeping operations show, antivehicle mine or improvised explosive thing and the injury that causes is still in rising trend, this is because Tank and Armoured Vehicle is when being subject to such and attacking, a lot of casualty accidents are not due to plate armour and puncture and caused, but are caused by the detonation impact energy transmitted to human body by the structure such as vehicle, seat.
Therefore, there are the following problems for prior art: motor vehicles blast protection shock wave scarce capacity, security protection performance is inadequate.
Summary of the invention
It is an object of the invention to provide a kind of vehicle blast protection shock wave floating floor structure, under the premise protecting the injury that vehicle is caused by base plate dispersed shock wave, reduce the detonation impact energy that shock wave is transmitted to member by vehicle floor further, to reduce damage.
For achieving the above object, the technical scheme is that a kind of vehicle blast protection shock wave floating floor structure of design, including:
It is positioned at body bottom, the protection base plate extended along length of wagon direction,
It is fixed on vehicle body, is positioned at directly over protection base plate and protects a pair rectangular steel tube that base plate extends in the same direction, is divided into protection both sides, baseplate width direction,
With above-mentioned a pair rectangular steel tube one_to_one corresponding, be individually fixed in a pair rubber mounting that corresponding square steel pipe top face extends in the same direction with corresponding rectangular steel tube,
The floating floor that base plate extends in the same direction is fixed and protects, with above-mentioned a pair rubber mounting end face, respectively in width two ends;
Described floating floor includes the two-layer of stacked on top of one another: be positioned at the composite floor on upper strata, is positioned at the skeleton steel plate of lower floor; Described composite floor is by securing member and skeleton steel plate fastening; Described for the securing member of composite floor with skeleton steel plate fastening is included: to sequentially pass through the lag bolt of composite floor, skeleton steel plate and the nut supporting with this lag bolt;
It is positioned at the rectangular steel tube of width the same side of floating floor, rubber mounting and floating floor to be fastened by securing member; Described for the securing member that rectangular steel tube, rubber mounting and floating floor fasten is included: to sequentially pass through the stay bolt of composite floor, skeleton steel plate, rubber mounting, rectangular steel tube and the nut supporting with this stay bolt.
Preferably, described rectangular steel tube is together with automobile body welding.
Preferably, described protection base plate is V-type protection base plate.
Advantages of the present invention and having the beneficial effects that: a kind of vehicle blast protection shock wave floating floor structure is provided, under the premise protecting the injury that vehicle is caused by base plate dispersed shock wave, reduce the detonation impact energy that shock wave is transmitted to member by vehicle floor further, to reduce damage.
Rubber mounting is positioned between floating floor and rectangular steel tube, plays a supportive role and cushions, energy-absorbing function. Described rectangular steel tube supporting construction is alternatively the reinforcement of protection base plate.
When blasting, vehicle floor can produce impact upwards, and the floating floor that member rides can move downward by relative vehicle under the pressure of member, directly reduces the impact to member's leg; Simultaneously as floor deformation, it is possible to the effective energy consuming blast generation, reduces the energy passing to member, protects member further; Floating floor can effectively stop the kinetic energy shell fragment that blast produces, so the present invention can be substantially reduced the blast injury to occupant.
And present configuration is simple, improves on an existing structure, it is easy to accomplish with installation.
Stay bolt not only acts as the guide effect to rubber mounting, simultaneously works as effect floating floor and rectangular steel tube linked together.
Rubber mounting is damping element, it is possible to plays the effect absorbing energy, and can effectively alleviate and impact the injury brought to composite floor.
Compared with prior art, the present invention has a characteristic that the present invention
1, improve vehicle blast protection shock wave function: flexible floating floor can be subjected to displacement by relative vehicle body when blasting, and has certain energy-absorbing function, reduce the impact to member;Meanwhile, the floating floor of composite is adopted can effectively to stop the kinetic energy shell fragment that blast produces, so the present invention can be substantially reduced the blast injury to occupant.
2, less labor content: the present invention improves on existing vehicle structure, advantageously reduces cost, and the suitability is strong, and simple in construction, it is easy to accomplish with installation.
