Background
The automobile can protect personnel in the automobile as much as possible when accidents occur, and an airbag is arranged in the automobile and used for buffering the impact force.
The Chinese patent document of the grant publication No. CN209938522U is named as a mixed gas generator for a side airbag, and the specification describes that 'the first guide cup 4 and the second guide cup 7 are matched for use, so that the guide buffering is effectively carried out', and 2 guide has the guide effect and also has the effect of blocking pressure waves.
In the above technical documents, the existing air bag generator mostly includes a structure for blocking pressure waves, such as a guide cup, so as to create a curved path for the pressure waves, and the pressure waves squeeze inert gas to the guide cover along the curved path, so that larger internal pressure is required to be consumed; therefore, the balloon generator must increase its structural strength to counteract the higher internal pressure (iop), which is a design requirement for the tortuous path design.
Therefore, there is a need in the market for a structure of an air bag generator that can stably walk through pressure waves in the air bag generator without increasing the structure of the air bag generator.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
In one embodiment, referring to fig. 1, a gas generator for an airbag includes a gas generator body 10, the gas generator body 10 including a housing 12 containing a gas mixture 13, a squib assembly 14 secured to one end of the housing 12, and a pod 16 secured to an opposite end of the housing 12.
The squib assembly 14 receives the ignition signal and activates the airbag inflation. The squib assembly 14 includes a squib sleeve 18 for receiving a squib 20. The squib assembly 14 is known and similar to the start-up assembly of existing gas generators, further details will not be described.
The ignition tube 20 and the air guide sleeve 16 are positioned at two ends of the shell 12, the explosion-transfer medicine support assembly 22 is fixed in the shell 12, the explosion-transfer medicine support assembly 22 is positioned at the upper end of the ignition tube 20, the explosion-transfer medicine support assembly 22 is provided with an annular space 30 for placing explosion-transfer medicine 36, the center of the explosion-transfer medicine support assembly 22 is an open center opening 33, and the center opening 33 faces the air guide sleeve 16.
The booster support assembly 22 includes a booster support 24 and a booster cap 32.
See fig. 1, 2 and 3. A gap exists between the booster support 24 and squib sleeve 18 to allow gas flow.
The booster support 24 comprises a tubular body 26, the tubular body 26 is a metal round tube, an annular cover 28 is installed at one end of the tubular body 26, the inner diameter edge of the annular cover 28 is installed on the tubular body 26 in a matching manner, a through center of the annular cover 28 and the tubular body 26 after connection is provided with a central opening 33, and in the embodiment, the cross section of the annular cover 28 is U-shaped and is integrally connected with the tubular body 26; in other embodiments, the inner diameter of the annular cap 28 may be greater than the outer diameter of the tubular body 26, the annular cap 28 being nested within the tubular body 26, the outer diameter rim of the annular cap 28 still being secured to the inner wall of the housing 12.
The outer diameter rim of the annular cover 28 resiliently engages the inner wall of the housing 12.
The other end of the tubular body 26 is provided with a medicine cover 32, the medicine cover 32 is a hollow ring body, the inner diameter edge of the medicine cover 32 is sleeved on the outer side of the tubular body 26, and the outer diameter edge of the medicine cover 32 is matched and arranged on the inner wall of the shell 12;
the annular space 30 is the space enclosed by the outer wall of the tubular body 26, the inner wall of the housing 12, the annular cap 28 and the drug cap 32.
The inner diameter edge and the outer diameter edge of the medicine cover 32 are turned over towards the same direction to form a turned-over edge;
referring to fig. 1, 4 and 5, the inner diameter edge of the cap 32 is elastically abutted against the outer wall of the tubular body 26, and the outer diameter edge of the cap 32 is elastically abutted against the inner wall of the housing 12, so that the cap 32 can slide relative to the tubular body 26 to adjust the space size of the annular space 30 in order to adapt the amount of the booster charge 36 in the annular space 30.
The cap 32 is U-shaped in cross-section with the bottom of the U-shaped structure in the cap 32 abutting the booster charge 36 in the annular space 30, i.e. the bottom of the U-shape facing the annular space 30 and the cap 28.
Referring to fig. 1, 2 and 3, the tubular body 26 is provided with a plurality of openings 34 communicating the central opening 33 and the annular space 30, the openings 34 are arranged in rows along the circumferential direction of the tubular body 26, and the openings 34 are distributed on the tubular body 26 in 2 rows of 10 openings 34 each.
The openings 34 are used to control the combustion of the booster charge and to provide a continuous heating of the inert gas. The opening 34 is sized to receive the booster charge within the annular space.
A booster charge 36 is located within the annular space 30 and engages the annular cap 28. The booster charge 36 is loosely packed into the annular space 30 and unlike some prior designs, does not require bagging the booster charge.
Referring to fig. 1, 6 and 7, the tubular body 26 is sleeved with a sleeve 37 for shielding the opening 34, and the sleeve 37 is a paper tube. A sleeve 37 is located between the annular cap 28 and the drug cap 32, the sleeve 37 being frictionally secured to the tubular body 26. The sleeve 37 is used to prevent the passage of booster particles through the aperture 34 without affecting the function or operation of the airbag inflator 10. The sleeve 37 may be held in place by the drug cap 32.
Referring to fig. 1 and 8, the pod 16 includes a plurality of baffle apertures 40. In this embodiment, the number of the guide holes 40 is 6, and in other embodiments, the number of the guide holes 40 is 7, 8 or 9. The burst disk 38 is located at the inner mouth of the pod 16. In some embodiments, burst disk 38 is a cross-shaped disk that includes a pair of linear score lines intersecting at the center of disk 38 to form a cross-shaped score pattern. The cross score line controls the manner in which the rupture disk 38 bursts, thereby preventing fragments of the rupture disk 38 from blocking the deflector aperture 40 in the pod 16.
Working principle: the squib assembly 14 receives an electronic activation signal to activate the squib 10. Activation of the squib assembly 14 will break the squib sleeve 18, thereby igniting the booster charge 36 and causing a pressure wave to propagate to the outlet burst disk 38, thereby opening the disk 38.
The openings 34 serve to control combustion and provide sustained heating of the inert gas in the housing 12 as the booster charge 36 burns. The orifice 34 controls the flow rate of the gas combusted from the booster charge 36. The pod 16 inhibits the flow of gas, thereby controlling the sum of the time for the gas to reach the pressure in the bladder. The number of deflector holes 40 and the size of the openings in the pod 16 are specifically configured to prevent gas from entering the balloon too quickly, which could otherwise cause the balloon to expand, or to enter the balloon too slowly.
The open center in the booster support assembly 22 provides a clear path for the pressure wave generated by the squib 20 assembly 14. Thus, the gas generator body 10 can be operated with a lower internal operating pressure, which increases the safety factor. The openings 34 in the booster support 24 control the combustion of the booster 36 and provide a continuous heating of the inert gas in the housing 12, which further increases the safety margin. This design also reduces the time to first fill, which is an advantage over previous tortuous path designs.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above examples, and all technical solutions belonging to the concept of the present invention belong to the protection scope of the present invention. It should be noted that modifications and adaptations to the present invention may occur to one skilled in the art without departing from the principles of the present invention and are intended to be within the scope of the present invention.
