Abstract
The utility model discloses a safety air bag for automobile drivers, comprising a mechanical transducer (1), a nitrogenous generator (2) and an air bag (3), wherein, the mechanical transducer is provided with a pyramidal coasting body (17) which can be rotated around a spring piece (16) connected with one end of the pyramidal coasting body whose the other end is abutted with the steel ball (21) of a clamping firing pin (20). The back portion of the firing pin is provided with a firing pin spring (19). When an automobile is crashed, the pyramidal coasting body responses deceleration and rotates around the fulcrum of the spring piece. The steel ball tightly pressed is loosened, and a percussion cap (29) is triggered under the action of the spring force to ignite starting mix (30) and nitrogen gas propellant (27). The gas generated is filled into the air bag to protect drivers.
Description
The utility model relates to a kind of air bag device that is used to protect automobile driver, and it is made up of mechanical sensor, nitrogen gas generator and airbag.
Busy day by day along with the increase of automobile quantity and communications and transportation is because of the casualty accident that auto against causes is on the increase.At present, states such as U.S., day have all carried out the research to auto against, have developed various safety devices, and Automotive Safety Air Bags is considered to have most the device of development prospect, Japanese magazine " car equipment " (" self-moving vehicle
Equipment ") the 10th phase of nineteen ninety published one piece of article " airbag apparatus relatively " (" エ ァ バ Star グ シ ス テ system
The Ru relatively ") a kind of airbag apparatus of being made up of mechanical sensor, nitrogen gas generator and airbag disclosed.When automobile high-speed collides, mechanical pick-up device induction deceleration/decel, arming, the firing pin percussion primer is also lighted starting mix, nitrogen generating agent, generation nitrogen charge into airbag.This apparatus structure is simple, but in order to make this airbag apparatus reliable operation, requires the firing pin in its mechanical pick-up device with drive link to be arranged high-precision the cooperation, thereby assembling is difficult, cost is high.
The purpose of this utility model be to provide a kind of simple in structure, its mechanical pick-up device quality of fit is low, cost is low, assembling is easy to air bag device.
For achieving the above object, the mechanical pick-up device in the utility model has adopted the taper coasting body, and it can be around propping up spot wobble with the contacted spring leaf of one end, and its other end heads on the steel ball that blocks firing pin, and the firing pin back is being subjected to the application force of striker spring.
After adopting said structure, adopt common processing technology, just can realize high reliability request, and be easy to assembling.
More insure for the work that makes the air bag device mechanical sensor, two covers coasting body, firing pin, striker spring and steel ball in parallel arranged in the mechanical sensor.
When the break-in circle that a change gas flow direction is set over against the place of deflation hole at the outside face of gas generator upper body, just can avoid the residue damage airbag of thermal current and trace.
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is the utility model air bag device structural representation.
Fig. 2 is the structure cross-sectional schematic of mechanical sensor in the prior art airbag apparatus.
Fig. 3 is the cross-sectional schematic that the mechanical sensor of the utility model air bag device is in safety position.
Fig. 4 is along the cutaway view of A-A line among Fig. 3.
Fig. 5 is the cross-sectional schematic that the mechanical sensor of the utility model air bag device is in the percussion state.
The utility model air bag device shown in Figure 1 is made up of mechanical pick-up device 1, nitrogen gas generator 2 and airbag 3.The upper body 25 of nitrogen gas generator 2 and following body 11 are fastenedly connected by screw, and its inside comprises the starting mix chamber 110 that starting mix 30 is housed, the combustion chamber 111 that granular nitrogen generating agent 27 is housed and the filter chamber 112 that is made up of two filter layers 22,23.Mechanical pick-up device 1 is positioned at the cavity of the following body 11 of 110 belows, starting mix chamber, igniter cap 29 corresponding sections have through hole 113 in 110 bottoms, starting mix chamber and the mechanical pick-up device, be surrounded by aluminium foil 28 around the side, starting mix chamber, there is boss 47 inside of following body 11, to fix cover 14 and overcoat 13 in first filter layer, be tied with the iron net between these two supporting sleeves, copper mesh, glass fiber mesh, form first filter layer 22, both played filtration residue, play the effect of absorbing and cooling temperature again, the internal diameter of following body 11 is littler than the internal diameter of upper body 25, like this when last, when following body matches, can form a step surface, to fix the second filter layer supporting sleeve 12.Have deflation hole 48 on upper body 25 walls, nitrogen can charge into airbag 3 thus.
The structure of the mechanical pick-up device in airbag apparatus comparison one literary composition as shown in Figure 2, when automobile is run into obstacle, deceleration/decel is during greater than a certain rated value, inertia ball 61 acts on downwards on the drive link 62, thereby spring 63 is discharged, promote firing pin 64, percussion primer 29, light starting mix 30 and nitrogen generating agent 27, the gas of generation charges into airbag 3.
The structure of the utility model mechanical pick-up device such as Fig. 3 be to shown in Figure 5, and when the deceleration/decel of auto against obstacle during less than a certain predetermined value, the spring force of striker spring 19 makes firing pin 20 compress steel ball 21, and steel ball 21 and flexure strip 16 compress coasting body 17 again.In this case, above-mentioned each other part all is in safety position shown in Figure 3.When the deceleration/decel of collision obstacle greater than a certain predetermined value, coasting body 17 is with the overcome friction square, be fulcrum with spring leaf 16 as shown in Figure 5, working direction along car is rotated, steel ball 21 discharges firing pin 20, at this moment firing pin 20 is subjected to striker spring 19 effects, percussion primer 29, and this mechanical sensor adopts two cover coasting bodies in parallel, the machine insurance mechanism of ball type as seen from Figure 4.
Outside at nitrogen gas generator upper body 25.Over against the place of deflation hole 48, be provided with a break-in circle 10, be used to change gas flow direction, to avoid the residue damage airbag 3 of thermal current and trace.Airbag 3 adopts polyamide fabric to make, and is shaped as ellipse garden shape, and volume is 60 liters, and internal layer scribbles poly-chloroprene rubber.
Can adopt the nitrogen gas generator and the airbag of other structure in the foregoing description.Every air bag device of being made up of mechanical pick-up device, nitrogen gas generator and the airbag of band taper coasting body and firing pin all drops within the protection domain of the present utility model.
