Hole and the assembly mechanism that cools, the cooling assembly mechanism includes the spray bag equipped with cooling medium, described to spray in bag and the air bag
Hymecromone crosses hot sealing suture, slot is provided with air bag inner bag of the spray bag with the air bag inner bag suture, in institute
Spray bag is stated with being provided with mechanical needle acanthopore on the spray bag of the air bag inner bag suture.
As the improvement of above-mentioned technical proposal, the black absorbing material layer be arranged on by way of thermal spraying it is described
On the madial wall of air bag inner bag.
As the improvement of above-mentioned technical proposal, the air bag inner bag is shaped as chondritic, and the air bag inner bag
Maximum volume is the 30-45% of gasbag maximum volume.
As the improvement of above-mentioned technical proposal, sealing is provided with around the gasbag and the gas generator junction
Connection sheet assembly, the sealed connection piece assembly are sutured with the gasbag by hot pressing, and on the sealed connection piece assembly
It is provided with drying layer.
Compared with prior art, implementation result of the present utility model is as follows for the utility model：
A kind of high temperature resistant automobile air bag described in the utility model, its is simple in construction, meet it is easy to use before
Put, start gas generator when colliding, air bag inner bag and gasbag expand immediately, now, in stronger height
Under moderate pressure effect, the slot of air bag inner bag and spray bag suture damaged can open under high temperature and high pressure effect, in spray band
Cooling medium can be extruded under high temperature and high pressure effect by mechanical needle acanthopore, cooling medium can be carried out to high temperature hot gas stream
Cooling effect, the problem of temperature is too high after gas inflated can be overcome, avoid air bag because temperature is too high and damaged, and cooled
Rapidly, effect is very good, it is ensured that human body will not be improved practicality by secondary injury, have preferable security performance, full
Foot actual operation requirements.
