Multi-layer multi-group airbag air distributor

Abstract

The invention relates to a multi-layer multi-group airbag air distributor which comprises air transportation pipelines, airbag fixing device fixing pressing plates, air distributor upper cover retaining screws, a mounting rack fixing iron plate, a signal connecting line, electric detonator mounting racks, electric detonators, a firing pin mounting rack, firing pins, air cylinder sealing pieces, multiple groups of small air cylinders and the like. The multi-layer multi-group airbag air distributor is made of thick iron plates and composed of an upper portion and a lower portion, and the shape of the multi-layer multi-group airbag air distributor is a flat square. Air outlets of the multi-layer multi-group airbag air distributor are connected with automobile safety initiative multi-layer multi-group outer anti-collision airbags through the air transportation pipelines. A rectangular iron plate is installed in the middle of the air distributor to be used as the mounting rack fixing iron plate which is used for fixing the electric detonator mounting racks, the electric detonators, the firing pin mounting rack, the firing pins and locking recoil generated by the electric detonators during explosion. The air cylinder sealing pieces and air cylinder air transportation pipelines are arranged between the firing pins and the small air cylinders. Air inlets of the air distributor are connected with the multiple groups of small air cylinders through the air transportation pipelines, and the air inlets of the air distributor are separated from the small air cylinders through the air cylinder sealing pieces which are used for sealing high-pressure air in the small air cylinders. The air cylinder sealing pieces are installed on the rear wall of the air distributor, and the small air cylinders are also connected to the rear wall of the air distributor through the air transportation pipelines. The multi-layer multi-group airbag air distributor works through the small air cylinders filled with the high-pressure air and installed on the rear wall of the multi-layer multi-group airbag air distributor.

Description

technical field [0001] The invention relates to an active safety vehicle protection device for automobiles. It is an important part for multi-layer and multi-group airbags installed outside the car. In particular, it relates to a multi-layer and multi-group airbag gas distributor. Background technique [0002] With the progress and development of society, automobiles have gradually become the main means of transportation for people, so the incidence of traffic accidents is also on the rise. In particular, the traffic accidents caused by collisions account for a large proportion, causing serious losses and casualties to vehicles and personnel. Although countries all over the world have invested a considerable amount of manpower and material resources in a large amount of research and testing on car safety facilities, the results are not satisfactory. The bumper at the front of the car is still useless, and the anti-collision ability is quite limited. Safety airbag also can...

Problems solved by technology

Although countries all over the world have invested a considerable amount of manpower and material resources in a large amount of research and testing on car safety facilities, the results are not satisfactory. The bumper at the front of the car is still useless, and the anti-collision ability is quite limited. Airbags can't protect people from harm, and the explosive ejection will cause indirect damage to the human body

In addition, the gas in the existing inner airbag is a chemical gas-generating drug, and the gas produced has a high temperature and is very easy to burn out the airbag; secondly, the gas supply mode is a single channel, on the one hand, the gas supply speed is slow, and on the other hand On the one hand, once there is a problem in any link, the airbag cannot be ejected, and the protective effect cannot be achieved.
