Abstract
The invention is to provide an anti-thunder seat with a power absorber. The anti-thunder seat is formed by a helmet rack mechanism assembly, a backrest assembly, an installation rack assembly, a seat pad assembly and a pedal rack, wherein the backrest assembly and the installation rack assembly are connected via a four-connection rod mechanism. Upon landmine explosion impact energy of a vehicle cabin base plate can be obviously displayed and explosion impact energy transmitted to the seat can be reduced by a afterloading shearing suspension mechanism of the seat; and energy transmitted to human bodies can be further reduced by the power absorber, so human safety can be protected.
Description
Technical field
The present invention relates to a kind of lightning protection seat, it is adaptable to be assemblied on MRAP (panzer).There is the general requirement of the comfortableness taken under normal circumstances; when vehicle runs into landmine explosion; the impact energy that can highlight cabin base plate especially reduces the explosion impact energy being delivered to seat by the Rear mounted scissors suspension fork mechanism of seat; reduce the energy transmission to human body again through energy absorber further, protect personal security.
Technical background
It is increasingly recognised that in recent years, in cabin the performance of seat weaken underbody blast wave for the injury of human body in play vital effect, for this, Modern armored vehicle needs a kind of energy absorption seat.In order to ensure seat, there is good elasticity, it is possible to adopt roof-mounted or Rear mounted, to avoid being rigidly connected between seat and chassis, and prevent the foot of occupant from contacting with car bottom plate as much as possible, to reduce leg injury；Meanwhile, the both sides of occupant's head also add cushion, to reduce the amplitude of head double swerve.Additionally, at present also more commonly used can the four point seat belt constrained system of quick release, it is simple to occupant's escape.
Summary of the invention
One, structure
A kind of lightning protection seat (see diagram A), by the helmet support-folding lockable mechanism A1, quadric chain A2, seat mounting bracket A3, seat support plate A4, helmet support A5, backrest A6, four point seat belt A7, seat cushion A8, the critical piece compositions such as pedal frame A9, antivibrator A10, compression helical spring A11.
It is divided into the structure of upper-part composition: take component assembly, mounting bracket assembly and energy absorber core parts three part.
Take component assembly, mounting bracket assembly adopts quadric chain connection to be arranged to longitudinal scissors suspension, can move up and down at fore-and-aft plane, to avoid being rigidly connected between seat and chassis, and be constituted the core parts of energy absorber with two compression helical springs and antivibrator.When in blast wave is by cabin, floor is delivered to seat, seat energy absorption device reduces the energy transmission to human body further.
Take component assembly also can be divided into: helmet bracket assembly, backrest assembly, cushion assembly, pedal frame assembly and four point seat belt five part.
Helmet bracket assembly and backrest assembly connect with articulated form, realize three gears by helmet support-folding lockable mechanism and regulate in fore-and-aft plane, and helmet bracket assembly both sides also add cushion, to reduce the amplitude of head double swerve；Cushion assembly and backrest assembly connect with articulated form, are equipped with torsion spring member and support cushion, it is achieved be flipped up and downward resiliency supported；Pedal frame assembly and cushion assembly connect with articulated form, pass through governor motion, it is possible to achieve duty locking, fit together with seat cushion after amounting to.

Detailed description of the invention
Absorb energy function
Operation principle (see diagram 2),
When explosion impact energy passes to seat mounting bracket B3 by car body, its moment is made to shift up, take component assembly (being made up of B5, B6, B4, B8, B9 parts), oriented bottom offset is produced by quadric chain B2 moment by original duty, compression spring B 11 and antivibrator B10, produce to absorb energy process, alleviate the phenomenon that people is produced to be thrown simultaneously.
Absorption energy process is as follows, when explosion impact energy (G) is instantaneously transferred to seat mounting bracket B3, and equivalence spring carried mass (occupant weight and suspension fork mechanism weight) reverse extrusion, suspension system is begun to decline by elemental height.In compression process, a part of impact energy (G1), store when helical spring produces compression, the potential energy (potential energy) changed into, another part impact energy (G2) overcomes the compression stress of antivibrator to become thermal energy consumption to fall.When suspension system arrives lower fulcrum position, it is stored in the energy in helical spring (G1) and starts release, in recuperation, a part of impact energy (G11) overcomes equivalence spring carried mass to make suspension system reset into rapidly elemental height state, and another part impact energy (G12) overcomes the recuperability of antivibrator to become thermal energy consumption to fall.Knowing from a cyclic process: antivibrator energy expenditure=(G2)+(G12), so circulation is only gone down directly, and impact energy (G) all decay are complete, convert thermal energy consumption to and fall.
Owing to landmine explosion completes in very short time, it is of interest that compression process energy expenditure (G2)
Namely energy is absorbed by chair mechanism, it is desirable to (G)-(G2) is the smaller the better.So that human injury is more little.
