Number in the figure explanation: 1 short circuit cap, 2 squibs, 3O shape seal ring, 4 guards, 5 band aluminium foil housings, 6 baffle plates, 7 aerogenesis tablets, 8 springs, 9 springs, 10 band medicine plugs, 11 deflation holes
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 occupant side electronic type gas generator of the present utility model, band aluminium foil housing 5 is for the middle part connects, the cavity structure of both ends open, and the diameter of its both ends open is slightly less than the middle part diameter; Joining with band aluminium foil housing 5 inside faces is provided with guard 4 with its coaxial core, and the length of guard 4 is less than the length of band aluminium foil housing 5, and a side end face and the squib 2 of guard 4 join, and its opposite side end face joins with being with medicine plug 10; Squib 2 is located at an end opening place of band aluminium foil housing 5, and in the short circuit cap 1 heart located therein hole, squib 2 is connected with the 5 inside face driving fits of band aluminium foil housing; Band medicine plug 10 is located at the other end opening part of band aluminium foil housing 5, and it is connected with the 5 inside face driving fits of band aluminium foil housing; Baffle plate 6 is located in the guard 4 end adjacent with squib 2, and its diameter is identical with empty diameters in the guard 4, and end face and spring 8,9 that band medicine plug 10 is positioned at the inboard join, and are provided with aerogenesis tablet 7 in the guard 4 between spring 8,9 and the baffle plate 6.
Place even 16 Φ, 2.5 deflation holes 11 that are furnished with of position symmetry of aerogenesis tablet 7 on the aluminium foil housing 5 in the corresponding guard 4.
Be provided with O-ring seals 3 in the groove that squib 2 and band aluminium foil housing 5 inside faces join.
Be provided with O-ring seals in the groove that band medicine plug 10 and band aluminium foil housing 5 inside faces join.
Guard 4 is netted multi-layer barrel structure and each laminar surface mesh shape difference for the surface.
When automobile crashes, sensor is experienced auto against intensity, electronic system receives the also signal of processes sensor, when judgement is necessary to open airbag,, trigger gas generator immediately by flip flop equipment generation ignition signal, gas generator produces a large amount of gases rapidly after receiving signal, and be full of airbag, make driver and crew to contact, rather than fiercely collide with the interior trimming parts of automobile with soft energy-absorbing buffering object.Rely on the deflation hole throttling damping of airbag to absorb the energy of collision, thereby reach the purpose that reduces the injury protection occupant.
Adopt a kind of occupant side electronic type gas generator of the present utility model, adopt between air bag module and the producer and get angry the location of part head and partly cooperate, and be fixed by support on the module and screw with the localization part of module.Receive the signal of electronic system reception and processes sensor when squib 2 after, squib 2 is got angry, get angry the flash hole of part by the band medicine and light aerogenesis tablet 7, gas generant composition in accordance burning back forms high temperature and high pressure gas, further filter again by guard 4 and the effect of flame arrest after, the aluminium foil that band aluminium foil housing 5 is preset the deflation hole place breaks through, and then ejection gas, in the regular hour, act on and finishing, in the airbag of gas spirt safety air bag, open airbag, thereby finish its effect.If in the gas generator working process, carry the higher flame of aluminium foil housing 5 ejection, might cause airbag to scorch or burn brokenly, do not have safety guard-safeguard occupant's effect.The different design of the multilayer of guard 4 and each laminar surface mesh shape can be played the effect of flame arrest and cooling.And adopt the spray orifice design of not having even 16 φ 2.5 of cloth on the shell of gas generator, then can play effects such as reducing enclosure interior temperature and pressure.Through experimental verification, this gas generator is in actual measurement, and the no flame or the length of flame are low less than 5mm, body skin temperature.
Therefore, adopt a kind of occupant side electronic type gas generator of the present utility model, overcome the traditional product service behaviour Unstable, have the technical problem such as potential safety hazard, when the utlity model has burning hull outside do not have flame or flame height is extremely low, Internal pressure stabilises, case temperature is low, overall performance is stable, the plurality of advantages such as safe and reliable.
