[0002] Generally, an airbag module is installed on the steering wheel of a passenger car. The main function of the module is to provide an inflated airbag between the driver and the steering wheel in case of an emergency collision to protect the driver's safety. The airbag module mainly includes parts such as an airbag, a shell and a pressing mechanism. Currently, there are two common ways to press the horn for the main driver: one is to press the horn through the multi-function button on the steering wheel, and the other is to press the horn through the floating pressing mechanism of the airbag module itself. The airbag module with a pressing function usually adopts two connection structures between the pressing mechanism and the shell assembly: one is a threaded connection structure, and the other is a snap-on connection structure.
