Miniaturized full-cloth copilot airbag box body

Abstract

The invention relates to the technical field of automobile safety airbags and discloses a miniaturized full-cloth copilot safety airbag box body which comprises a safety airbag box body made of a PA66material, an airbag is arranged in the safety airbag box body, a clamping plate is arranged at the bottom of the airbag, and a gas generator is arranged at the bottom of the clamping plate. The copilot airbag box body is formed by tailoring and sewing cloth, the product consistency is good, and the quality of batch production of copilot airbags is stable; the passenger airbag is wrapped by full cloth, a metal box body is not needed, the manufacturing process of the full cloth box body is simple, the processing period is shortened, the product weight is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile airbags, in particular to a miniaturized full-cloth passenger airbag box body. Background technique [0002] Automobile safety, energy saving, and environmental protection have become the three major issues facing the automobile industry and even the entire human society, and the automobile safety issue is the first to bear the brunt. Car safety can be divided into active safety and passive safety. The passive safety devices widely installed and used in automobiles mainly include safety airbags. Safety airbags are a product with high technical content in the passive safety of automobiles. The air is opened so that the occupant's body will not hit the steering wheel, instrument panel and windshield, avoiding secondary collisions for the occupants; at the same time, preventing the occupants from being thrown out of their seats in dangerous situations such as vehicle rollover. The protection pri...

AI Technical Summary

Problems solved by technology

At present, the co-pilot safety airbag box widely adopts a box structure composed of multiple sheet metal parts welded. Due to the limitation of stamping sheet metal, this kind of box body is generally welded by two or three sheet metal parts. In order to provide a stable structure connected with the external body beam bracket, body instrument panel bracket, and body instrument, it is usually necessary to weld square nuts at their corresponding positions. After the above processes are completed, the box body needs to be galvanized, Paint spraying treatment, in the whole production process of this stamped box body, multiple welding and other process treatments are required, which will gradually amplify some errors and deformation effects in the manufacturing process, and finally cause the shape and position accuracy of the box body Low height and unstable size, the outstanding performance is that the consistency of the box body is difficult to guarantee, which affects the consistency of the entire airbag and makes it difficult to control the mass production quality of the airbag; at the same time, the metal box needs to develop molds, and the processing technology is cumbersome. Defects of heavy product, high production cost, inability to meet body and space layout requirements, and low adaptability
