Specific embodiment
It is an object of the invention to reduce in explosion environment driver leg to injure, thus under providing a kind of military vehicle lightning protection
Limb protective device disperses explosion energy, to reduce small leg strength, occupant's wound is effectively reduced by buffering the impact from floor
Evil.
The protective device includes foot pad and flexible energy-absorbing floor, and the foot pad is fixed on flexible energy-absorbing floor with rivet
Top；
As shown in figure 4, the foot pad 6, including 1 two parts of semi-circular tube 3 and upper flat plate.Wherein the semi-circular tube 3 is put down with upper
Plate 1 is connected by rivet, establishes close connection to enhance foot pad bonding strength.Upper flat plate 1 provides support peptizaiton.
The military vehicle lightning protection foot pad is deformed by self structure, is absorbed and is transmitted under occupant under explosion environment from floor
The impact of limb reaches and reduces the power that lower limb of passenger is subject to, to reduce personal damage.
The distribution of semi-circular tube 3 is opened in three misarrangements, reaches protective effect by compressing energy-absorbing, design requirement is greater than for number of rows
2, every row's semi-circular tube number is greater than 3.
The upper flat plate 1 provides the effect of support dispersion, and sufficient intensity can carry human foot's strength, 1 ruler of upper flat plate
Very little reference man's foot well, is designed as regular rectangular shape, places convenient for foot, while further absorbing the energy after resisting compression energy-absorbing
Amount.
As shown in Figure 1-3, a kind of military vehicle lightning protection foot pad, including 2 two parts of upper flat plate 1 and semi-circular tube.It is wherein described
Semi-circular tube 2 compresses energy-absorbing when by blast impulse, thus the explosion energy that dissipates.Entirety being capable of excellent support human leg weight
Amount.
Semi-circular tube 3 is distributed in the lower section of upper flat plate 1 in three row's displaced manners, it is contemplated that processing technology, gap between semi-circular tube 3
Setting is greater than 2mm.Upper flat plate 1 and semi-circular tube 3 are by installing rivet interlacement in 3 interstitial site of semi-circular tube.To guarantee the steady of structure
Qualitative, every section of 3 two sides number of rivets of semi-circular tube guarantees to be greater than 2.Reach uniform stressed and consumption by the design of three misarrangement open semicircle pipes 3
It can effect.3 design requirement of semi-circular tube is that number of rows is greater than 2, and 3 numbers of every row's semi-circular tube are greater than 3.
The features such as 6 material requirements ductility of foot pad is good, stable structure, hardness and strength are higher considers cost and lightweight
Target, this example select H14 aluminum material.
According to Analysis on Static Stiffness as a result, when applying 1kN power, the foot pad linear deformation with a thickness of 0.3mm is 8.65mm, thick
The foot pad linear deformation that degree is 0.4mm is 3.97mm, referring to design requirement: displacement < 5mm when 1kN, therefore, Footpad thickness design
It should be greater than 0.4mm.In conjunction with AEP-55 standard, i.e., small leg strength peak value < 5.4KN, when Footpad thickness is 0.5mm, small leg strength is down to
It is minimum.In conjunction with Static stiffness and torque requirement, design thickness is 0.5mm in this example.
1 size of upper flat plate meets human foot's placement space and guarantees that there are certain surpluses for two sides.It is set in this example
It is calculated as 310 × 310mm.
As shown in figure 5, the floor 7 includes upper plate 2, bracket 4 and bottom limit connection 5 three parts of frame.The wherein bottom
Portion's limit connection frame 5 and upper plate 2 are connected by bracket 4, and connection frame 5 is limited with bottom respectively by bolt for bracket 4 and upper plate 2 connects
It connects.Wherein right angle rack not only acts as connection function, can also buffering energy-absorbing.
The upper plate 2 is partly installed in 4 upside of bracket, and hollow design arranged side by side of interlocking separates plate outer ring and inside.
In explosion time, by Fracture Deformation, by the partial cut of the power of 2 outer ring of upper plate transmitting and the contact of inner ring foot, to reduce transmitting
To the power of human foot.
The bracket 4 is partly installed in 5 inside of 2 downside of upper plate and bottom limit connection frame, provides a supporting role.Using straight
Angle support had not only guaranteed its Static stiffness but also had been conducive to process.When energy transmission to floor, bracket 4 can reach energy-absorbing effect by deformation.
The bottom limit connection frame 5 is partly installed in 2 downside of 4 outside of bracket and upper plate.Bottom limit connection frame 5 with it is upper
It is hollow design between plate 2, deformation space is provided for upper plate 2, to reach part energy-absorbing effect.
By explode occur when vehicle from vehicle frame transmission force to limitting casing 5 to bracket 4 and upper plate 2, at upper plate slot
Deformation occurs, the transmitting of blocked force, reaches energy-absorbing effect, and hollow out upper plate and bottom limit connection frame combination reach flexible effect,
It reduces explosion and reaches human leg's energy.
The lightning protection floor reaches flexible protective effect by energy-absorbing buffering.
Floor is installed below driving staff foot, and whole to be installed in a manner of sinking, i.e., upper plate 2 is integrally concordant with floor,
It is bolted, strong applicability, replacement is convenient.Wherein upper plate 2 is bolted with bracket 4, and bracket 4 and bottom limit connect
Frame 5 is connect to be bolted.There is the slot of strip to be staggered around three sides on upper plate 2, strip slot length range is 30-
60mm, width are≤10mm, and along strip direction, slot interval takes 20-40mm, and slot number of rows is 2-5 row.This example is 45mm*
5mm is divided into 30mm between the slot of strip direction, totally three rows, is spaced 5mm.
As shown in Fig. 2, bracket 4 is L-type structure, the face being in contact with upper plate 2 is not to stop slot as boundary.Limit connection frame
5, in c-type, highly directly affect the performance on floor.After total height is to explode, upper plate 2 and limit connection frame 5 be not in contact for
Lower limit, the upper limit is related with specific vehicle, and setting height is 72mm in this example.
When car body is by blast impulse, vehicle bottom impact is transferred to floor first, is deformed by bracket 4 and upper plate 2
Energy-absorbing, upper plate 2 play position-limiting action, prevent sheet frame from bumping against to lower recess, bottom limit connection frame 5.Dump energy is transferred to people
Body leg.In whole process, driving staff's leg injury is significantly reduced.
When car body is by blast impulse, vehicle bottom impact is transferred to floor 7 first, and bottom limit connection frame 5 plays
Position-limiting action prevents upper plate 2 and bottom from limiting connection frame 5 and bumps against.Then energy transmission to foot pad 6, semi-circular tube 3 itself compression is inhaled
Can, the power dissipation of upper flat plate 1 is echoed, dump energy is transferred to human body lower limbs.In whole process, energy-absorbing effect is significant, multiplies and drives
Personnel's leg injury significantly reduces.
