Description
Technical field
The present invention relates to airbag device field, more particularly, relate to a kind of safety air bag with automobile of speeding.
Background technology
Automobile since being born at the end of last century, more than 100 year of trials and hardships of having passed by.When automobile is convoy on single track with speeding, rear car follows the motoring condition of front truck, and namely front truck and rear car reach information communication, and rear car is according to the information of front truck, car parameter differences before and after contrast, is scaled rear car and drives scheme and realize automatic Pilot.Safety air bag namely in order to when reducing automobile generation head-on crash due to the injury to chaufeur and occupant that huge inertia causes, therefore safety air bag is for very important with automobile of speeding.
Safety air bag comprises outer cover, gas generator, air bag buffering substantially.The expansion gas that air bag buffering is supplied by gas generator is opened, and outside the expansion gas that gas generator process inside is filled, also comprises inflator, after inflator outburst, launches gas and is supplied to air bag buffering.
The expansion gas of the outburst supply of inflator is high-temperature gas, and now, gas generator, except release launches gas, also discharges the high temperature impurity of high temperature.But, when the high temperature impurity of high temperature touches air bag buffering, hole can be produced, i.e. corrosion hole in air bag buffering.
Existing technology, in order to prevent corrosion hole, adopting structure as shown in Figure 4, namely adopting guard ring, and wherein guard ring comprises the curve stopping sill and be positioned on obstruction sill, makes high temperature impurity fly to the inside stopping sill.But due to curve structure as shown in Figure 4, high temperature impurity can drop on the top of gas generator, as shown by the arrows in Figure 4, because the impulsive force of gas is strong, the high temperature impurity of minority very easily rebounds, and namely acts on the top of air bag buffering, still can produce corrosion hole.Adopt existing structure, its corrosion that high temperature impurity can not be stoped completely to cushion air bag.
Summary of the invention
Technical matters to be solved by this invention is to provide the safety air bag with automobile of speeding, its erosion that can prevent high temperature impurity from cushioning air bag completely.
The present invention's adopted technical scheme that solves the problem is:
With the safety air bag of automobile of speeding, comprise the guard ring in air bag buffering and air bag buffering, barrier flaps is provided with in described air bag buffering, described barrier flaps comprises the first barrier flaps and the second barrier flaps, the first described barrier flaps and the two ends of the second barrier flaps are all connected to air bag buffering upper and the first barrier flaps and the second barrier flaps and mutually intersect, and the first described barrier flaps and the both sides of the second barrier flaps are provided with high temperature impurity adhering layer.The present invention improves on the basis of existing technology, one, arranges barrier flaps, intercept the bounce-back approach of high temperature impurity in air bag buffering; Its two, barrier flaps arranges high temperature impurity adhering layer, avoid high temperature impurity occur second time bounce-back.As shown in Figure 1, high temperature impurity rebounds on gas generator, ejects the opening of guard ring.Because the bounce-back direction of high temperature impurity has certain gradient, in air bag buffering, barrier flaps is set, high temperature impurity is caught in its bounce-back process, namely high temperature impurity finally sticks on the high temperature impurity adhering layer of barrier flaps, avoid high temperature impurity that second time bounce-back occurs, namely the approach of completely isolated high temperature impurity contact air bag buffering, prevents the erosion that high temperature impurity cushions air bag completely.Because guard ring is square, the bounce-back direction of high temperature impurity is four direction, the first barrier flaps and the second barrier flaps mutually arranged in a crossed manner, can ensure to adsorb the high temperature impurity in each direction.
As preferably, the first described barrier flaps and cross connection place of the second barrier flaps are provided with barrier sheet, and the bottom of described barrier sheet is provided with high temperature impurity adhering layer.Can find out in the research process to high temperature impurity bounce-back approach, high temperature impurity finally can stick on the high temperature impurity adhering layer of the first barrier flaps and the second barrier flaps.Optimize, adopt barrier sheet, the motion of high temperature impurity can be stopped as early as possible, namely adopt the motion of barrier sheet to high temperature impurity to stop, make it in barrier sheet place and stop motion.
Further, described air bag buffering is circular after launching, and cross connection place of the first barrier flaps and the second barrier flaps is positioned at the center of air bag buffering.Cross connection place of the first barrier flaps and the second barrier flaps is positioned at the center of air bag buffering, make each chamber separated by the first barrier flaps and the second barrier flaps, its volume is equal, and what can ensure to inflate in gas replenishment process is even, namely at same time, the air pressure of each chamber is equal.
Further, the first described barrier flaps is mutually vertical with the second barrier flaps.First barrier flaps and the second barrier flaps perpendicular, all have barrier flaps and its sense of motion place plane orthogonal when can ensure that high temperature impurity rebounds, ensure to high temperature impurity absorption validity.
Further, described barrier sheet and the first barrier flaps and the second barrier flaps perpendicular, namely reduce the contact angle of high temperature impurity and barrier sheet, ensure that the effective absorption to high temperature impurity.
To sum up, the invention has the beneficial effects as follows:
The present invention arranges barrier flaps in air bag buffering, intercepts the bounce-back approach of high temperature impurity, avoids high temperature impurity to contact air bag buffering, can prevent the erosion that high temperature impurity cushions air bag completely.
