Embodiment 1

[0024] Embodiment 1: as figure 1 The shown secondary delayed detonation inflatable gas generator includes a lower casing 1 and an upper casing 2, the opening end of the lower casing 1 extends outward to form a connecting ring 20, the opening end of the upper casing is connected to the lower casing The open ends of the body are connected by friction welding; the upper shell 1 and the lower shell 2 are connected to form a closed medicine storage chamber 3, the medicine storage chamber is provided with a gas-generating medicine 4, and the lower shell is provided with a fire tube container 5 The open end of the fire tube container 5 is provided with an ignition tube container 6, the ignition tube container 6 is provided with an electric ignition tube 7, the outside of the ignition tube container is clamped with the lower shell, and the fire transmission tube container 5 is provided with a fire transfer powder 8 , the fire tube container 5 is provided with a plurality of first vent...

Embodiment 2

[0030] Embodiment 2: as Figure 4 As shown, a pressure-triggered ignition mechanism 15 is provided in the middle of the cover plate 14. The pressure-triggered ignition mechanism 15 includes an ignition hole 30 arranged on the cover plate and a pressing piece 31 bonded to the outer end of the ignition hole. Can be broken when pressed. After the gas-generating drug in the drug storage chamber is ignited, a large amount of gas is generated. When the air pressure in the drug storage chamber reaches a certain value, the compressed tablet ruptures under pressure, and the high-temperature gas burned by the gas-generating drug in the drug storage chamber enters from the ignition hole. into the auxiliary medicine box, thereby igniting the gas-generating medicine in the auxiliary medicine box, and realizing secondary delayed detonation and inflation.

Abstract

The invention relates to the technical field of safety airbags of automobiles and discloses an inflatable gas generator capable of achieving a secondary delayed detonation. The inflatable gas generator capable of achieving the secondary delayed detonation comprises a lower shell and an upper shell. The upper shell and the lower shell are connected to form a closed explosive storage cavity. Gas generation explosives are stored in the explosive storage cavity. A starting mix pipe container is arranged on the lower shell. An ignition pipe container is arranged at the open end of the starting mix pipe container. An electric ignition pipe is arranged in the ignition pipe container. Starting mix is placed in the starting mix pipe container. A plurality of first exhaust holes are formed in the starting mix pipe container. A plurality of second exhaust holes are formed in the two sides of the upper shell. An auxiliary explosive box is arranged in the explosive storage cavity. The bottom of the auxiliary explosive box is connected with the bottom surface of the lower shell through a connecting block. A cover plate is arranged at the open end of the auxiliary explosive box. The cover plate is connected with the auxiliary explosive box in a clamped mode. Gas generation explosives are placed in the auxiliary explosive box. A pressure trigger ignition mechanism is arranged in the middle of the cover plate. The inflatable gas generator capable of achieving the secondary delayed detonation has the beneficial effects that secondary delayed detonation can be conducted, gas is continuously provided for an air bag, and smooth unfolding of an air bag module is facilitated.

Description

technical field [0001] The invention relates to the technical field of automobile airbag components, in particular to a gas generator for an airbag. Background technique [0002] The airbag is a very important safety device on the car. When an accident occurs in the car, it can effectively reduce the damage to the human body of the accident, thereby protecting the lives of the driver and passengers. The airbag is mainly composed of a gas generator, a combustion chamber, a filter / filter, an explosive / expanding agent, a gas-generating agent / gas-generating agent, an ignition device / ignition tube, a vent hole, a medicine box and other components. Airbag Gas Generator: A component that generates and releases gas in an automotive airbag system. Combustion chamber: The cavity filled with gas-generating powder (gunpowder) in the gas generator. Filter / Strainer: Filters the gas produced and retains solid residues in it. Propagating powder / expanding powder: A kind of gunpowder that ...
