Description
Technical field
The utility model relates to the vehicle passive safety technical field, particularly the gas generator used of automobile driver side airbag.
Background technology
Common automobile driver side airbag gas generator is a pyrotechnic DAB gas generator at present, and its characteristics are: loam cake separates with subpanel, is one with laser welding; Loam cake and body all adopt punch forming, and the material of taking usually is high 301 stainless steel materials of intensity, and the drawback that this class gas generator exists is as follows:
1. loam cake separates with subpanel, increases a part;
2. many one welding sequences increase a laser welder;
3. two parts are welded, and are difficult to guarantee the position of mounting hole, cause user installation to use difficulty;
4. use 301 corrosion-resistant steels, the material cost height.
Summary of the invention
The utility model is intended to solve orthodox car driver side safety air bag and uses be difficult to accurate location and installation hole site, user installation that gas generator exists that difficulty, manufacturing process are complicated, cost high-technology problem, so that the design of a kind of loam cake and subpanel integral type, accurately location and installation hole site, user installation is convenient, manufacturing process is simple and cost is low automobile driver side airbag gas generator to be provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of automobile driver side airbag gas generator of the present utility model, wherein body 2 driving fits of loam cake 1 and band steel foil are connected to become main cavity, ignition tube 16 perforations are passed loam cake 1 and are stretched in the aforementioned cavity, the medial surface of loam cake 1 is provided with cushion rubber II 7, the gas generant composition in accordance chamber 4 that is surrounded by guard seal cover cap 5 and guard 6 is positioned at the main cavity middle part, guard seal cover cap bottom is provided with cushion rubber I 3, in the gas generant composition in accordance chamber 4 gas generant composition in accordance is arranged.
A kind of automobile driver side airbag gas generator of the present utility model wherein is respectively equipped with mounting flange hole 17 on four of loam cake 1 jiaos.
A kind of automobile driver side airbag gas generator of the present utility model, wherein ignition tube 16 is by squib 11, igniter 12, light a fire tablet 13, base 14 and body 15 formed automatically, wherein base 14 is located at the top of body 15, squib 11 and base 14 are connected with core, igniter 12 and automatically igniting tablet 13 be located at base 14 bottoms.
A kind of automobile driver side airbag of the utility model beneficial effect of gas generator:
1. loam cake and subpanel integral type design reduces the part number, simplifies manufacturing process flow;
2. accurately location and installation hole site, user installation make things convenient for;
3. reduction manufacturing cost.
Description of drawings
Fig. 1 front view
Fig. 2 birds-eye view
The number in the figure explanation: 1 loam cake, 2 bodies, 3 cushion rubber I, 4 gas generant composition in accordance chambeies, 5 guard seal cover caps, 6 guards, 7 cushion rubber II, 11 squibs, 12 igniters, 13 are igniting tablet, 14 bases, 15 bodys, 16 ignition tubes, 17 mounting flange holes automatically
The specific embodiment
The utility model detailed structure, application principle, effect and effect with reference to accompanying drawing 1-2, are illustrated by following embodiment.
Consult shown in Fig. 1-2, a kind of automobile driver side airbag gas generator of the present utility model, wherein loam cake 1 has adopted flat shape and the mounting flange of being connected of big arc and little lunch box to be structure as a whole, and has so both guaranteed loam cake intensity to have guaranteed eccentric requirement again; Independent flange part and welding sequence have been removed simultaneously.
Be respectively equipped with mounting flange hole 17 on four jiaos of loam cake 1.
This gas generator has adopted the integral structure design, and each constituent elements is relatively independent, has separately technical requirements and inspection specification, helps production, assembling and the quality control of each parts like this.Also help to simplify the fitting process of finished product, make the overall performance of gas generator and quality controlled easily, thereby have favorable manufacturability.
After gas generator is subjected to the next certain galvanic action of extraneous transmission, squib is at first got angry, the ignition powder ignition retard is lighted aerogenesis tablet in the housing by certain passage, the gas that produces when aerogenesis tablet burning back reaches the steel foil that breaks through behind certain pressure on the body after by the guard filtration, spray a certain amount of gas, make the safety air bag smooth opening, finish its function.
Therefore, adopt a kind of driver's side airbag gas generator of the present utility model, have loam cake and peace The design of sabot integral type reduces number of components, simplifies manufacturing process flow; Accurately location and installation hole site, user installation are conveniently; Many beneficial effects and the technological merits such as the reduction manufacturing cost is low.
