Description

A kind of air bag fluid feed line device and system

The present invention relates to a kind of system that has improved, in order to protection and help that those are collided, urgent victim that fire and noxious gas leakage etc. threaten.

At present, there are more than 400,000,000 roadlice and truck travelling on the All Around The World.None is not to move with the speed of giving the sizable kinetic energy of passenger for aircraft, automobile, steamer and bicycle.If this kinetic energy is not dissipated gradually, will cause the passenger injured.Each year, the people of killed or wounded is more than the people of killed or wounded in Vietnam War or Korean War in vehicle traffic accident.Be involved in the vehicle in the collision case, need better protection system at the passenger.Except the injures and deaths that cause because of collision, those blasts owing to industrial accident, fire and noxious gas also all can cause large-scale damage, death and wounded or disabled.

Aspect protection collision victim, air bag has shown positive effect.There are some problems in air bag in order to protection passenger in fire and traffic accident at present, and is unfavorable aspect several, comprising:

1 air bag can not guarantee that the victim does not suck the dangerous smog that catches fire.

2 air bags can not guarantee that the victim avoids noxious gas and/or makes us the harm of smothering gas.

3 usefulness are so that the solid fuel that air bag expands produces offensive radiation and residue such as triazo-compound.

4 solid fuel systems are dangerous in the originating firm of producing them, and a lot of accidents have taken place.

The residue that chemical that 5 solid fuels are adopted when producing and production process all can produce hostile environment causes handling problems.

The ignition system of 6 traditional air bag fuel system is insecure, and produces deletrious accessory substance.

7 have been applied to the hydro-carbon of air bag and the common problem of amino gaseous state, liquid state or " fluid " fuel comprises: burning before toxicity and burning or chemical reaction process in the generation of toxic substance.

8 fluid fuels must mix with oxidizer, and in flammable ratio, send in the spark gap of spark source at the required correct time branch of ignition.It is difficult doing like this, because enter the big variation of the air velocity of the geometry that fuel sprays, has caused different fuel penetrating depths and penetrates partially.

9 in order to generate the suitable fuel and the compound of oxidizer, be convenient to spark ignition, fluid fuel will be from fuel injector directive spark source, causes always having quite a large amount of fuel to be ejected into by in the waste of heat district of the shell that member limited of spark source ambient air capsule.Can cause the inhibition of burning and/or the cause thermal damage of air bag member like this, and the bag that usually causes because of underexpansion, bag fold and/or distortion is special-shaped and the leakage when being collided by the traffic accident victim etc. seriously jeopardizes the integraty of air bag.

10 with regard to using fluid fuel, and the trial of doing in the past all is insecure, because during being in very long stand-by state, fuel can leak in reservoir gradually.The state here all is the general state of transport applications.

In the 11 former air bag expansion systems, in very long standby period owing to do not detect the deferred reaction of the compound of leakage gradually and/or fuel and oxidizer, thus enough quick pressure capacity be lowered into a problem.

Fig. 4 is the schematic cross sectional views according to a kind of device of principles of construction of the present invention, and it is in order to the fluid mixture of storage of fuels and oxidizer, sprays this stored mixture and light this compound when it sprays the inside of air bag into.

Fig. 5 is the scheme drawing according to a kind of system of principles of construction of the present invention.

Fig. 1 shows an air bag assembly 1, it has container 2, in order to store suitable fluid, such as a certain amount of fuel material, this fuel material can be to select from the group of being made up of hydrogen, ammonia, methane, propane, butane, methyl alcohol, ethanol, air, nitrogen monoxide, nitrogen dioxide, oxygen, nitrogen, active metal and water, they are stored and are delivered into combustion chamber 8 by valve module 4,4 fuel valves of valve module and ignition system double action.The control of valve module 4 is realized by controller 14, it is desirable to by electric pulse control, and this electric pulse has filled electric capacitor stores in controller 14 as one.From valve 4 spray in the suitable oxidizer that is stored in the container 8 fluid fuel preferably by spark ignition, light or unite by catalyst and light by spark and catalyst, this depends on the size of air bag, the cost of system and the shelf life of hope.For providing the surge of suitable voltage, spark ignition preferably is stored in battery, inducer or the cond in controller 14.Can under the situation of the instrument electric system that suspends traffic because of collision, guarantee to open like this by electrically-energized valve 4 and the required electric energy of generation electro spark.This mode makes the present invention to be installed on the handlebar with the system of cheapness or is installed in the chest harness, so that protection cycling person.Because ensure by the electric energy that is stored in the controller 14, so, can guarantee that air bag launches.

The priming signal that launches air bag can be produced by inertia switch controller assemblies 14 in or accelerator switch, perhaps by other devices, produces such as the signal that is positioned at the seat belt actuator (not shown) generation outside 14.

Preferably burning in the zone 8 in the air excess in being included in container 6 of the fuel of carrying by valve 4.Under the situation that air in container 6 is fully heated, pressure is elevated at desirable position spalling container 6, and air bag 16 is just promptly launched by escaping gas in container 6, and causes capsule 16 pressure inside to raise.Container 6 is preferably made by the thermoplastic material of low elastic modulus, such as polyethylene or polyester, apply with aluminium in the inboard of container 6, and the pattern that some have reduced thickness is set, so that press the geometric figure spalling, can prevent like this that air bag 16 from bumping against because of excessive heat or with the corner angle of point destroys, and distributed heat air equably, guarantees that air bag 16 launches rapidly.

Embodiment shown in Figure 1 has overcome the many defectives and the difficulty of prior art.It is desirable to; fuel and oxidizer are stored in the container under condition of high voltage; these containers are contained in a fail-safe and drain in the guiding bag 36, and this bag 36 has a desirable discharge-channel 35, and this discharge-channel 35 can deflect from gas the people's of air bag protection position.When air bag launches, protective bag 36 by the annular in the folding corrugated regions of air bag 16 expand disconnect so that reach that desirable air bag 16 expands and to passenger's protective effect.Fluid fuel is such as the hydrogen that is stored in the container 2, can mix mutually with the compound of water with the compound or the ethanol of water with fluid ratio such as calcium chloride, generate a kind of anticold additive, so that help the sealing of chamber 8, prevent the leakage of hydrogen when long term storage, and, just in case slowly leak, but hydrogen make-up.Enter capillary tub and micropore capillaceous and guarantee under the situation of the fuel of having selected hydrogen, carbonic oxide, methane and ammonia and so on for use that with the liquid that reaches sealing effectiveness ability the fuel gas storage system has a long storage life with its suitable antirust composition that carries and corrosion inhibitor.Have found that using fluid sealing agent and erosion resisting solution is one that can solve in the important improvement of the difficult problem of long term storage molecule under high pressure conditions.The representative type corrosion inhibitor comprises the NaNO that is used for Alfer ₂, Na ₂CrO ₄, Na ₂MoO ₄

With regard to existing systems, the problem of difficulty especially is the fuel of air bag, such as hydrogen may leak or deferred reaction to its stage that is exhausted fully, thereby can not reach the purpose that air bag is launched.The invention solves this problem, the present invention utilizes some right sensors 26,28,30 and 31 to monitor reserve temperature and pressure in container 2 and 6, so that judge that whether complete can this system and trouble free service.

If the pressure of the fuel material in the tank is reduced to below the predetermined threshold, then can change into hydrogen and heavily store up fuel being stored in container 2 water interior or that be stored in the additional reservoir by the work of electrolysis electrode 32 and 34.Water and iron have generated ferric hydroxide in the electrochemical reaction at an electrode place.Then discharge hydrogen at another root electrode place, with to container 2 pressurization.When voltage is higher, can generate hydrogen and oxygen, the oxygen of generation can as required or be delivered into tank 6 or be delivered into container 2.The present invention except the gaseous hydrogen cartridge 2 that provides utilization to discharge from the water that is stored within the airtight container 2 a kind of so safe, easily the production technology, also provide the measure of various faults automatic safe, these measures are all by controller 14 controls.If the insufficient pressure that pressure sensor 26 is judged in the container 2 so, will be applied to voltage on electrode 32 and 34,, reach the pressure of expectation until producing enough hydrogen.Temperature and pressures in the container 2 are monitored, judge leakage rate and with memory device in the predetermined value of storing compare so that urgent warning and require to repair.This system program can be arranged to produce suitable warning, alarm bell or interlocking, so that equipment can not move before repairing.

Add another effect in the fuel advance to be stored in the container 2 or that be stored in the fluid additive in the oxidizer in the container 6, provide and a kind ofly weaken the measure of combustion of hydrogen, so that reduce the peak temperature of the gas that discharges by the air bag expansion phase with cooling system conditioner.Representative type weakens agent and comprises one or more of following material: nitrogen; Water vapour; Carbon dioxide; The compound of ethanol and water; The compound of sodium bicarbonate, water and ethanol; The compound of calcium chloride, sodium chloride or muriate of potash and water, acetic acid, argon, helium, ammonia, ammonium hydroxide and air excess.

For bigger air bag, preferably ammonia and/or the hydrogen solution with a suitable flowing fluid ratio such as water, ethanol and rare acetic acid is stored in the container 2.When airbag deployment, in container 6, this compound of hydrogen and light acetic acid can burn till sodium bicarbonate and AIR MIXTURES.Water vapour, carbon dioxide and air excess are full of container 6 with a gratifying temperature, break until it, and are full of air bag 16 rapidly, so that provide protection to the occupant of the vehicle that is equipped with apparatus of the present invention.The compound of fast burn hydrogen and acetic acid in the zone of container 6 is at this, because of acetic acid exhausts in excessive sodium bicarbonate, so can guarantee not have the acid ease in air bag 16.

In a kind of safe capsule expansion system that is specially adapted to little or big air bag, has a certain amount of reactant, these reactants are selected from the group of being made up of hydrogen, ammonia, methane, propane, butane, methyl alcohol, ethanol, air, nitrogen monoxide, nitrogen dioxide, oxygen, active metal and water, they are stored in the container 2, and by a suitable valve 4 flow to the reaction distributing box 5, at distributing box 5 places, technology by selecting from be made up of catalysis material, spark discharge, shearing spout and hot material one group causes the reaction of at least a reactant.This system also comprises a control circuit 14 in order to maneuvering valve 4.According to the size of the air bag that will expand, utilize various measures, the pressure in the container 2 are maintained the degree of the size that is suitable for the air bag that will launch with an amount of regulating.These measures comprise: electrolysis, metal-acid reaction, metal-water reaction, metal-cmpd reaction and catalytic cracking.The a part of reactant that utilizes the technology of selecting will be stored in the container 2 changes into the gaseous state composition, so that produce the pressure store of wishing.

Hydrogen can extremely promptly burn.Can guarantee that like this reaction expected and the expansion of air bag 16 all finish rapidly.The air bag compact storage, and at vehicle collision, be about to bump or when catching fire, launch rapidly by the expansion of air bag.For the speed of expansion and degrees of expansion of repairing air bag and the amount that makes the gas of protecting capsule to expand and producing; a certain amount of reactant is selected from the one group of material being made up of hydrogen, ammonia, methane, propane, butane, methyl alcohol, ethanol, air, nitrogen monoxide, nitrogen dioxide, oxygen, active metal and water that is stored in the container 2; and by valve 4 flow to the reaction distributing box 5; at reaction distributing box 5 places, react from least some in the reactant of container 2 and the reactant that is stored in second container 6.It is desirable to, pressurized air and diluent are contained in the container 6, yet plan is that pressurized air and the cmpd such as water, ammonia or the ammonium hydroxide that contain hydrogen are contained in the container 2, and the reactant of hydrogen and so on is contained in the container 6.The initiation of the reaction between the reactant can realize by any suitable means, comprising catalyst material, spark discharge, shearing spout and hot material.It is desirable to, the control of the pressure and temperature on vitals and surface, key realizes that by the intermittent use of valve 4 valve 4 can be piezo-electric type, electromagnetic type or air-driven type.

Device shown in Figure 2 can be used as a complex that integrates fuel storage, conduit, control cock and air bag detecting device, perhaps as the valve 4 among Fig. 1 or the preferred embodiment of the valve 170 among Fig. 5.This device can be very compact and storage of fuels effectively, as the oxide of the inwall of high pressure air, helium, argon or the hydrogen that comes by the water decomposition around the electrode 71 and oxygen and/or graphic 43.Give electrode 71 power supplies with a covered wire 77.In order to be adapted to medium-sized and large-scale air capsule, electrode 71 is preferably cylindrical, and by the flange support tube wall that is positioned at part 60, ccasual, dielectric.One double burned metal or pory polymer filtration plug (not shown) preferably are set between electrode 71 and member 48.

Particularly advantageously be, by solenoid coil 46 press seals within the high-intensity box hat 44 and the containers 60 in the member 43 are strengthened, solenoid coil 46 is around this single-piece high pressure storage container 60.Helium, nitrogen or air can be with 10, and 000PSI or higher pressure are stored in the container 60, so that be used for expanding air bag cheaply.For bigger safety air bag, by the burning of suitable fuel ratio such as hydrogen is next corresponding expansion phase is strengthened, so hydrogen produces by a spot of water of electrolysis under the gas storage pressure in container 60.

The control of air bag speed of expansion, expansion condition and degrees of expansion is to carry out such as 55 among Fig. 2,62 and 63 by detecting device.This pressure information is used for determining what degree when air bag expand, expand into, and when the protege be subjected to expansion phase collision, have how many people protected.If the protege is child and has lower impulse force buffering requirement, then uses injection system frugally.If the protege is the adult or exists big impulse force to need buffering, then in the train of impulses of a series of weak points, use valve module 40, to enlarge the degree of required cushion rubber.In the initial 15-20 millisecond of collision sequence, Electronic Valve 48 can be opened more than 15 times, and supercharging distributes and generation meets protege's build and the required cushion rubber of impulse force requirement to optimize.The correction of the cushion rubber state that this set of vehicle acceleration and air bag pressures, readings information and the intermitten by valve 40 carry out is favourable; it can promptly reach protection purpose and don't overinflation air bag and injury traffic accident victim, particularly child and weak patient.

Because the pressure in the polymer insulator 64 on insulator 72 increases, this polymer insulator 64 passes to valve seat 54 to power.Using under the situation of piezoceramic disk 63, it is desirable to select to make the material of insulator 64, making it have enough Poisson displacements that the power that applied by fuel pressure causes, so that produce a sizable axial force and on sensor disk 63, produce piezoelectric signal.In this case, it is desirable to select to have the poly-phenylene sulfide of filling than the material of low elastic modulus such as unfilled ETFE rather than harder material such as glass.

By a power or " pressure " sensor 63 are set between valve seat 54 and insulating polymer 64, then reactant reaction in 69,22 and 134 and pressure transient can be monitored.Being used for the useful especially pressure sensor of this purpose is strain gage and piezoelectric gauge, comprise ceramic-like such as quartz and barium titanate, polymer class such as polyvinylidene fluoride (PVDF).O type ring 62 on the valve seat 54 can be made with this material, so that promptly reach sealing effectiveness again as pressure sensor.This distortion of materials can produce a voltage signal, and this voltage signal is detected, to determine from valve seat 54 to electrode nozzle the fluid pressure in 70 the passage.Changing the axial force that is produced by the pressure in the reaction zone 8 is also detected by the O type ring 62 of the piezoelectricity on the valve seat 54.O type ring 62 can be in the electrostatic field of the last one molded forming, so that piezoelectric property to be provided, perhaps after molded, handle, to produce piezoelectric effect.

Cover worn-out O type ring 62 and, can make voltage signal from assembly, to take out by enough suitable cables, pass to a peripheral control unit with electrically conductive ink plating O type ring or by surperficial plating NiCu electrode pattern at O type ring.The pattern of electrode can be well-designed, to strengthen the used signal of fuel pressure monitoring, perhaps strengthens the used signal of combustion chamber prrassure monitoring, and perhaps electrode pattern can be designed to monitor simultaneously the activity of the two, so that regulation speed of expansion and buffering effect.

From being positioned at Valley Forge, this piezoelectric (PVDF) of all thickness and size can be buied by the Pennwalt company of PA19482.Have found that, PVDF dish 63 with following size can play the effect of reactant pressures and catalyst chamber reaction monitoring device well, promptly, its outer dia equals the interior hole size of shell 76 at valve seat 54 places, and its diameter of bore equals the interior hole dimension of graphic O type platen, about 50 microns of its thickness.Preferably electrode be made in valve seat 54 and exhausted level body 64 contacted two faces on.If seat 54 is metallo-s and by contact and ground connection with shell 72, just then only an insulated wire of need lead to controller outside and be enough to monitor important pressure activity.

Using under the situation of piezoceramic disk 63, preferably selecting to make the material of insulator 64, making it have enough Poisson displacements that the power that applied by fuel pressure causes, so that produce a sizable axial force and on piezoceramic disk 63, produce piezoelectric signal.In this case, it is desirable to select to have the poly-phenylene sulfide of filling such as glass such as unfilled ETFE rather than harder material than the material of low elastic modulus.

The another kind of shape of piezoelectric transducer is a right cylindrical such as shown in Figure 2 65,67 or 69.This class external diameter is 6.35-25.4mm (0.25 ＂-1.00 ＂), and conventional wall thickness is that 0.51-1.27mm (0.02 ＂-0.05 ＂) and cylinder length can be buied up to the cylindrical piezoelectric sensor of 300mm or 12 ＂.These devices can be ordered from " AtochemSensors, P.O.Box 799, Valley Forge, PA.19482 " is special.Flowing through pressure and the combustion chamber prrassure circulation that the fuel of tubular space 61 transfers out causes piezoelectric gauge 65,67 or 69 to produce electric signal.The rising of pressure and reduction detect by component assembly 53,55,70,72 and 64 in the expansion phase.Produce piezoelectric signal by sensor 55,62,63,65,67 and 69.But the storing state of monitoring reaction thing and expansion phase like this, with the decision service conditions such as the temperature that causes by expansion phase, pressure and stress.The pressure and temperature state that determine to solve allows and sprayed and the measure of the heat effusion trend that response characteristic is caused by fuel can promptly be optimized the expansion of air bag.The measure of this solution pressure detection problem and the characteristic of course of reaction provide than traditional " blow formula " measure more fast and more widely to the control and the optimization of expansion phase.

In when work, by force gauge 55 and 63, the O type ring 62 that detects power or some other sensor being connected to a suitable circuit as 65 etc. electrode and they being monitored, with the generation of definite piezoelectric signal.Operated by the device of Fig. 2 in order to other suitable pressure sensor of determining stress, pressure and temperature rising state, they comprise:

1 fiber-optic device in this device, is placed an interferometry formula cavity resonator between a fiber optic end face and a Reflective mode silicon sheet chip that approaches.This chip plays a diaphragm, and crooked or crooked along with moving of material around along with different pressure, and said material around is out of shape because of the pressure in the reactant gas delivery path and the pressure in the catalyst chamber.This crooked cavity depth that changes as the function of diaphragm radius of diaphragm, and at the total spectral reflectivity of pressure adjustment.In intensity, frequency, phase place or these four basic variables that polarize any one can be selected for use, with by this light transmitting fiber instrument detected pressures.Intensity modulation is a simple case, and here, catoptrical resulting intensity is just represented the pressure of fuel conductor and combustion chamber.One suitable source of this device is the state of Michigan, " the Fiber Optic Sensor Technologies " in Ann Arbor city.Referring to Fig. 2, material 55 is regarded as the light transmitting fiber coupled configuration of opto-electronic pickup 53.

2 polysilicon piezoelectric gauge members, it is by on the bonding pipe 61 of substrate such as Fig. 2 that is bonded to temperature coupling of chemical vapor deposition or molecular linkage, perhaps on the face of valve seat 54 or on 55.This class device can be buied from the peculiar limit of sieve phase awns company that Ming Nisu answers state, Eden Prairie city, and perhaps " Dresser/Ashcroft " from Connecticut State Stanford city buys.

3 have the capacitive transducer that uses light transmitting fiber, two-way transmitter sensitive or mobile cart communication.All types ofly all use a little capacitive silicon sensor.This class device can be buied from the Industrial Co., Ltd of Fuji of Tokyo.Referring to Fig. 2, the 55 light transmitting fiber coupled arrangement of regarding opto-electronic pickup 53 as.

4 ceramic diaphragms can be used for capacitive pressure transducer.Such pressure sensor is suitable and can buys from the Endress+Hauser Instruments in the Greenwood of Indiana city.

5 determine that along with the change of frequency the tuning fork instrument of pressure also suits, and this pressure sensor is measured natural frequency with piezoelectric element.This device can be from buying in " Yokogwa " in Georgia State Newman city u s company.

6 fiber-optic devices, in this device, catoptrical intensity is adjusted with the deformable metallo-mirror that is coated with of a pressurized.A diaphragm with reflecting surface is equipped with in the end of fiber, and this diaphragm plays a variable parasite.This diaphragm is crooked or crooked with moving of material around with different pressure, and said material around causes distortion by the pressure in the fuel conductor or the pressure in the combustion chamber.This bending of diaphragm has changed the catoptrical amount as the function of diaphragm radius, and adjusts total spectral reflectivity of light at pressure.

When work, when fuel flowed to catalyst chamber, piezoceramic disk 63 sent a signal along with the rising of hole 61 internal pressures.

A kind of liquid that for example has the ethanol of 50% distilled water and 50% and be added with sodium bicarbonate carbonate can provide enough antifreezing effects, can reach-34 ℃ of C (37).The solution that another example that also forms leak free solution capillaceous when antifreeze function is provided is made up of 70% glycerine and 30% distilled water, its crystallization when-39 ℃ (38).Another solution that is used for this purpose is the compound of ethene, ethylene glycol and water, and when wherein distilled water was 50%, its antifreeze temperature that reaches was about-39 ℃ (38 °F).Can change according to material institute requirement in order to the anti-corrosion additive by the various members of building fuel reservoir and combustion systems.
