Description
Technical field
The utility model relates to seat field, is specifically related to the anti-land mine seat of a kind of vehicle.
Background technology
The armor facing technical merit of modern armed vehicle is more and more higher, but the data that obtain from segregated area and peace-keeping operations show, antivehicle mine or simple and easy explosive and the injures and deaths that cause are still in rising trend, this is because Tank and Armoured Vehicle is in the time being subject to such attack, a lot of casualty accidents are not to cause because plate armour is breakdown, but by passing through vehicle, the structures such as seat cause to the detonation impact energy of human body transmission, if armchair structure design is bad, making to be finally delivered to occupant's shock wave energy with it can be up to 20～30 of the Human Tolerance limit times, the injures and deaths that occupant is caused threaten conventionally more serious than blast itself, very easily cause the major casualties such as human spine fracture.
The special vehiclees such as at present domestic Tank and Armoured Vehicle are unequipped special anti-land mine seat all, and seat has become the weak link of vehicle to land mine protection.Have the application of a small amount of lightning protection seat abroad, but installation and energy-absorbing mode are not coordinated application, energy-absorbing effect does not maximize, and can not adapt to the installation requirement of domestic vehicle.
Summary of the invention
The technical problems to be solved in the utility model is, for existing seat above shortcomings, provides a kind of vehicle anti-land mine seat, reduces to greatest extent impact energy, makes it to be reduced to the Human Tolerance limit, protection personal security.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
The anti-land mine seat of a kind of vehicle, comprises seat body, and described seat body is made up of seat frame, seat seat surface and energy absorber; Described seat seat surface is connected side and is provided with horizontal lower carry bar with seat frame, the two ends of described lower carry bar are connected with the sliding sleeve being socketed on the mobile jib of seat frame, in described sliding sleeve, be provided with linear bearing, linear bearing, sliding sleeve, lower carry bar slide up and down along mobile jib with seat seat surface; The middle part of described lower carry bar is connected with longitudinal adapting rod, and the upper end of adapting rod is hung on (described seat seat surface is hung on energy absorber by sliding sleeve, lower carry bar and adapting rod) on energy absorber, and the upper end of energy absorber is arranged on the middle part of carry bar; Upper carry bar is fixedly connected on the mobile jib of seat frame both sides.
Press such scheme, described energy absorber comprises sleeve, top connection, upper fixed guide cover, nut, extrusion piston, upper orienting sleeve, energy-absorbing rod, tension bar, middle orienting sleeve, lower orienting sleeve, lower fixed guide cover and lower adaptor, the upper end of described top connection is connected with upper carry bar by bolt, and the lower end of top connection is socketed in the upper end of sleeve by upper fixed guide cover; Described extrusion piston is arranged on the upper end in sleeve; Described energy-absorbing rod is arranged on the inner chamber of sleeve by upper orienting sleeve, middle orienting sleeve, lower orienting sleeve, wherein, the adjacent extrusion piston of upper orienting sleeve, middle orienting sleeve is arranged on the middle part of barrel bore, and lower orienting sleeve is arranged on the bottom of barrel bore; Described tension bar is along the axis setting of sleeve, and tension bar is from top to bottom successively through extrusion piston, upper orienting sleeve, middle orienting sleeve, lower orienting sleeve and lower fixed guide cover, the upper end of tension bar by nut and extrusion piston is affixed and the upper end of tension bar just to top connection and leave certain interval, the lower end of tension bar is affixed by the upper end of nut and lower adaptor after overlapping through lower fixed guide, and the lower end of lower adaptor is connected with adapting rod by bolt.
Press such scheme, this seat also comprises suspension installing mechanism, and described suspension installing mechanism is by being fixed on the mounting means of car body sidewall or being fixed on the top fabricated section of car body top, and is fixed on the lower fabricated section composition of hull bottom plate; The top of seat body is connected by Quick-release pin with the mounting means or the top fabricated section that hang installing mechanism by the ears joint at seat frame top; The mobile jib and the lower fabricated section socket of hanging installing mechanism of seat frame both sides passed through in the bottom of seat body, after mobile jib and the socket of lower fabricated section, reserves certain interval at vertical direction.
Principle of work of the present utility model: when land mine or simple and easy explosive are in the time that vehicle bottom is blasted, detonation impact energy will upwards be transmitted by car body, car body floor is nearest apart from detonation point, can the very first time form violent plastic deformation, to be the most also that maximum detonation impact energy is upwards transmitted, but because mobile jib and lower fabricated section are at the reserved certain interval of vertical direction, detonation impact energy cannot upwards directly be transmitted by deformation, therefore be equivalent to block this bang path, also just prevented that maximum detonation energy from forming direct injury to human body.
And then, detonation impact energy continues upwards to transmit along car body sidewall, because bang path is far away, the structure meeting absorption portion energy of car body, and the mounting means of the suspension installing mechanism of seat is fixedly connected on car body side wall upper part, therefore the energy that seat receives has passed through the long range attenuation of car body sidewall, has also just reduced the injury that personnel may be subject to; If adopt top fabricated section to be fixedly connected with car body top, have better attenuating.
Blast impulse energy is passed to after seat, is passed to upper carry bar and energy absorber by the mobile jib of seat frame both sides, then is passed to successively adapting rod, lower carry bar, sliding sleeve and seat seat surface, is finally passed to human body from seat seat surface.In the time that detonation impact energy is passed to energy absorber, top connection and lower adaptor by energy absorber two ends stretch to the sleeve inner structure of energy absorber, lower adaptor pulls extrusion piston by tension bar and nut, thereby compression energy-absorbing rod, when the overload that energy-absorbing rod is subject to reaches certain threshold values, will there is compressive deformation, with attenuate shock energy; In this process, upper fixed guide cover and lower fixed guide cover in energy absorber play axially stable effect to tension bar, and upper orienting sleeve, middle orienting sleeve, lower orienting sleeve play guiding and stable effect to energy-absorbing rod.Energy-absorbing rod adopts special substance and technique to make, in the time that reaching design code value, bearing load can produce degeneration, by plastic deformation apparatus with shock absorbing, the compression of energy-absorbing rod starts the threshold values of load to be determined according to the Human Tolerance limit, to guarantee that the impact energy after decay can not damage human body.
The utlity model has following beneficial effect:
1, be applicable to the special vehiclees such as Tank and Armoured Vehicle, in the time being subject to the explosive threats such as land mine, extend the main bang path of land mine or simple and easy explosive detonation impact energy by hanging installing mechanism, reduce the detonation impact energy that is delivered to seat;
2, by the transmission of the further attenuate shock energy of energy absorber to human body is set; when the overload being subject to when seat reaches certain threshold values; will there is plastic deformation in the energy-absorbing rod of energy absorber, reduce to greatest extent the impact energy that occupant's health bears, protection personal security.
