Problems solved by technology

The traditional support ring is made of metal sheet metal material, which is heavy, limited by the stamping process, and has a relatively simple structure. It can only be formed by stamping and flanging to form a vertical wall
The inflation performance of the gas generator is not ideal
[0003] At the same time, when the gas generator is detonated, the surface temperature of the gas generator is extremely high, and the bag body of the airbag is folded and pressed on the gas generator, so the high temperature is easy to burn the bag body of the airbag
Therefore, there are certain limitations in the protection of the airbag body

Embodiment Construction

[0024] like figure 1 As shown, the automotive airbag support ring structure is composed of a dome 1, a wall 5 and a bottom plate 6 located around the dome 1, and the dome 1, the wall 5 and the bottom plate 6 are integrated and made of plastic material There are multiple round holes 2 on the dome 1, and the four corners of the dome 1 are special-shaped holes 3 (that is, the gap between the dome 1 and the wall 5). The number of round holes 2 in this embodiment for 5. Four corners of the base plate 6 are provided with screw holes 4 , which are approximately triangular in this embodiment, and reinforcing ribs 7 are provided between the wall body 5 and the base plate 6 . like figure 2 As shown, a plurality of small protrusions 8 are evenly arranged on the back of the bottom plate 6 .

[0025] like image 3 As shown, the bolts 9 are respectively loaded into the screw holes 4 of the support ring, and the heads of the bolts 9 are shaped. Interference fit, the bolt 9 is pressed i...

Abstract

A supporting ring structure for an automobile safe airbag is composed of a circular arch top, a wall body placed at the periphery of the circular arch top and a bottom plate, wherein the circular arch top, the wall body and the bottom plate are integrated and an injection molding part is adopted and the material of the injection molding part is plastic rubber. A plurality of round holes are formed in the circular arch top. Irregular holes are respectively formed in four corners of the circular arch top. Screw holes are formed in four corners of the bottom plate. According to the supporting ring structure for the automobile safe airbag, an air inflation function, for the airbag, of an air generator can be improved and the airbag can be prevented from being burnt. The supporting ring structure for the automobile safe airbag is low in cost and light in weight and accords with the development tendency of weight reduction of automobiles.

Description

technical field [0001] The invention relates to an automobile safety air bag support ring structure. Background technique [0002] The role of the support ring in the airbag device is to reduce the possibility of burning the bag body of the airbag by the high-pressure hot gas generated by the gas generator when the gas generator is detonated. The traditional support ring is made of metal sheet metal material, which is heavy, limited by the stamping process, and has a relatively simple structure. It can only be formed by stamping and flanging to form a vertical wall. The inflation performance of the gas generator is not ideal. [0003] Simultaneously because when the gas generator is detonated, the surface temperature of the gas generator is extremely high, and the bag body of the airbag is folded and pressed on the gas generator, and the high temperature easily makes the bag body of the airbag burn. Therefore, there are certain limitations to the protection of the air bag ...
