Description
Technical Field
The invention relates to a self-adaptive safety airbag structure, and belongs to the technical field of airbags.
Background
Along with the convenience of traffic, all can install the air bag that plays the protective action to the passenger on vehicles such as car and aircraft, after the air bag receives the collision, the solid material produces gas rapidly after being burnt and makes the air bag swell, contact with people after the air bag swells and contact with the hard article at the interval, avoid people and contact with hard article on the car and produce and bump injury, make the air bag play the protective action, after the air bag contacts with people, receive people's pressure, the air in the air bag is discharged from the exhaust structure that a vent on the air bag constitutes;
because the body of a passenger is different and the pressure generated on the air bag is also different, when the body of the passenger is a tall passenger, the pressure generated on the air bag is very high, the air bag is compressed and has suddenly increased rigidity due to the fact that an exhaust structure formed by one exhaust hole is difficult to quickly exhaust gas in the air bag, the air bag with the suddenly increased rigidity rebounds the human body in the collision process, and the risk of injury of the passenger in the collision process is increased.
Disclosure of Invention
In order to solve the technical problem, the invention provides a self-adaptive safety airbag structure.
The invention is realized by the following technical scheme.
The invention provides a self-adaptive safety airbag structure, which comprises:
the air bag can be expanded after being filled with gas, and an exhaust hole A for exhausting is arranged on the air bag;
the air bag is also provided with a self-adaptive exhaust structure, the self-adaptive exhaust structure can only bear a certain range of force, once the force exceeds the certain range, the pull belt falls off from the air bag, and the diameter of the exhaust hole B is smaller than that of the exhaust hole A.
The self-adaptive exhaust structure is multiple.
The self-adaptive exhaust structure comprises an exhaust hole B which is arranged on the air bag and used for exhausting, and a drawstring which is fixed on the air bag at the side of the exhaust hole B through a fixing structure blocks the exhaust hole B to form the self-adaptive exhaust structure, the fixing structure can only bear a certain range of force, and once the force exceeds the certain range, the drawstring can fall off from the air bag.
The exhaust hole A and the exhaust hole B are of damping hole structures.
Self-adaptation exhaust structure is fixed with the stretching strap through fixed knot structure including the air cock of intercommunication air pocket and the air pocket that is located the air cock side, and the stretching strap is plugged up the air cock gas outlet and is constituted a self-adaptation exhaust structure, and fixed knot structure can only bear the power of certain limit, in case surpass will make the stretching strap drop from the air pocket.
The fixed structure formed by sewing the drawstring by a sewing thread or gluing the drawstring by glue is fixed on the air bag to form the fixed structure which can only bear a certain range of force.
The gas generator is communicated with the air bag, the exhaust hole of the gas generator is communicated with the air bag, and the gas generator can rapidly generate gas filled in the air bag.
The invention has the beneficial effects that: the pressure applied to the air bag is larger at the moment that the passenger is in contact with the expanded air bag, after the pressure exceeds the bearing force of the fixing structure of the self-adaptive exhaust structure between the drawstring and the air bag, the drawstring is separated from the air bag, the exhaust hole B is exposed, and the exhaust speed of gas from the exhaust hole B and the gap between the drawstring and the air bag is reduced, so that the pressure in the air bag is slowly increased within a certain time, the rigidity of the air bag is prevented from being suddenly increased, the passenger with the passenger is prevented from being damaged by bottom-touching collision, and the pressure in the air bag is released due to the existence of the exhaust hole B and the exhaust hole A after the expansion.

Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1.
The invention relates to an adaptive airbag structure, comprising:
the air bag 1 can be expanded after being filled with gas, and the air bag 1 is provided with an exhaust hole A for exhausting;
wherein, still be equipped with the exhaust hole B that is used for carminative on the air pocket 1, the air pocket 1 of exhaust hole B side is fixed with stretching strap 2 through the fixed knot structure of suture 3 sewing or glue joint formation, and stretching strap 2 blocks up exhaust hole B and constitutes a self-adaptation exhaust structure, and fixed knot structure can only bear the power of certain scope, once surpass and to make stretching strap 2 drop from air pocket 1, and exhaust hole B diameter is little than exhaust hole A.
The air bag 1 is high and large, the pressure applied to the air bag 1 is large at the moment when the passenger contacts the expanded air bag 1, after the pressure exceeds the bearing force of a fixing structure of a self-adaptive exhaust structure between the drawstring 2 and the air bag 1, the drawstring 2 is separated from the air bag 1, the exhaust hole B is exposed, and the exhaust speed of gas from the exhaust hole B and a gap between the drawstring 2 and the air bag 1 is reduced, so that the pressure in the air bag 1 is slowly increased in a certain time, the sudden increase of the rigidity of the air bag 1 is avoided, the high and large passenger is prevented from being damaged by bottom-touching collision, and the pressure in the air bag 1 is released due to the existence of the exhaust hole B and the exhaust hole A after the expansion.
The exhaust holes a and B may be a damping hole structure.
The adaptive exhaust structure may be more desirably provided in plurality.
Self-adaptation exhaust structure also can be the air cock of intercommunication air pocket 1, and the fixed knot structure that air pocket 1 of air cock side was made up or is glued joint through glue through suture 3 is fixed with stretching strap 2, and stretching strap 2 is stopped up the air cock gas outlet and is constituted a self-adaptation exhaust structure, and fixed knot structure can only bear the power of certain limit, in case surpass and will make stretching strap 2 drop from air pocket 1.
The gas generator is communicated with the air bag 1, the exhaust hole of the gas generator is communicated with the air bag 1, after collision occurs, the gas generator rapidly generates gas, and the air bag 1 can be rapidly expanded after being filled with the gas.
If the collision intensity is small or the passenger is short, the pressure applied to the air bag 1 is small at the moment when the passenger contacts the air bag 1, the stitching 3 of the drawstring 2 is not broken enough, and the gas is discharged from the vent hole A of the air bag 1. When the collision intensity is larger or a large passenger contacts the air bag 1, the pressure applied to the air bag 1 is larger at the moment, the sewing thread 3 of the drawstring 2 is broken, the drawstring 2 is flattened, and the gas is exhausted through the exhaust hole A and the exhaust hole B, so that the passenger is effectively protected.
