Abstract
The present invention relates to a kind of control device being arranged between safe automobile air bag and multifunctional tool box, when there is relatively big traffic accident in vehicle, controlled opening device will receive air bag by sensor and open signal, process signal by electronic controller and send the unlatching of multifunctional tool box.So, this multifunctional tool box is just opened after vehicle occurs relatively big or major traffic accidents, effectively controls its service efficiency, power and safety.
Description
Technical field
The present invention relates to a kind of control device being arranged between safe automobile air bag and multifunctional tool box, occur bigger at vehicle
During vehicle accident, controlled opening device will receive air bag by sensor and open signal, process letter by electronic controller
Number and send the unlatching of multifunctional tool box.
Background technology
Along with development and the raising of automotive performance of highway, automobile driving speed is increasingly faster, especially because automobile has
Increasing sharply of amount, traffic is more and more crowded so that accident is the most frequent, so the safety of automobile just becomes particularly important.
The safety of automobile is divided into active safety and passive security two kinds, and active safety refers to the ability that automobile tries to avert accidents, mainly
There are control stability, braking ability, ride comfort etc.；Passive security refers to that, in the case of just in case major accident occurs, automobile is protected
Protect the ability of occupant, currently mainly have seat belt, safety air cushion, Anti-collision vehicle body and air bag guard system (Airbag
RestraintSystem, hereinafter referred to as air bag) etc..Due to the complexity of reality, some accident is difficult to avoid that, therefore
Passive safety is the most extremely important, air bag as the achievement in research of passive safety, due to easy to use, effect notable,
Cost is the highest, so being developed rapidly in China and popularize in recent years.
Although being equipped with the equipment such as various break-in tools on a lot of cars, major part is all to be directly installed on automobile by break-in tool,
But often not reached its using value by artificial destruction, even some people holds the crime of this instrument.
Summary of the invention
For convenience of member on car after the occurrence of the traffic accident can be effective and rapid use multifunctional tool box, the controlled opening square in this workbox
Case selects the scheme with air bag united opening and designs its controlled opening device.So, this multifunctional tool box is sent out at vehicle
Life relatively greatly or is just opened after major traffic accidents, effectively controls its service efficiency, power and safety.
The present invention is the auxiliary equipment in the series multifunctional workbox of saving oneself of vehicle mounted traffic accident, it is desirable to de-for wanting in great traffic accident
Each car owner of danger and passenger provide a actual protection, and reduce the heavy burdens for specialty fire-fighting, traffic police, rescue personnel, and raising is rescued
Protect quality.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings the present invention is further described:
Fig. 1 is air bag operation principle schematic diagram.
Fig. 2 is this multifunctional tool box controlled open theory figure.
Fig. 3 is specifically to eject circuit diagram.
Detailed description of the invention
As it is shown in figure 1, when automobile collides under steam, first received by crash sensor and clash into signal, as long as collision
Intensity meets or exceeds the intensity of setting, and crash sensor i.e. produces action and sends signal to SRS-ECU；SRS-ECU
After receiving signal, comparing with the data stored, if having met or exceeded the standard that air bag is ignited, then sending instruction,
Sent by drive circuit gas generator in SRS air bag component and start signal；After signal received by the lighter of gas generator
Ignite aerating agent, produces a large amount of gas.If impact strength can make sensor output electrical signals that SRS～ECU can not be made to send
The instruction (during collision, speed is 20～30km/h) of firing air bag, SRS-ECU is issued by causing the instruction of safety belt pretensioner,
Make belt pull, protection driver and occupant.
As in figure 2 it is shown, in running car, left front crash sensor, right front crash sensor and master reference are constantly by car
The information of speed change is input to electronic controller, constantly calculates through electronic controller, analyzes, compares and judges, and accurate at any time
Preparation goes out instruction.When speed is collided less than 30km/h, the signal that master reference sends can not make electronic controller send ejection
The instruction in workbox.So, when low speed (deceleration is less) collides, workbox will not be ejected.At a high speed (deceleration is bigger)
During collision, upfront sensor and master reference input shock signals to electronic controller simultaneously, and electronic controller is judging rapidly
After send instruction, be also turned on device for ejecting, eject workbox.When automobile generation head-on crash accident, workbox controls system
System detects that, when impulsive force (deceleration) exceedes setting value, ejection circuit connected immediately by workbox computer, is ejected in workbox.
As it is shown on figure 3, in the driving circuit, photoelectric coupling is utilized to realize the isolation of control circuit and main circuit, to ensure circuit
Safety and improve capacity of resisting disturbance.In order to prevent mis-ignition, a safety mechanical sensing of connecting between firing circuit and air bag
Device.He is a mechanical type acceleration transducer in principle, is also lighted a fire with the ejection circuit of safety sensor circuit in parallel
The control of signal.Being in normally open under normal circumstances, when deceleration reaches some strength, sensor closes, it is allowed to igniting
Electric current passes through.
