Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, specifically relating to an airbag press structure. Background Technology

[0002] Most passenger cars are equipped with an airbag module on the steering wheel. The main function of this module is to provide an inflatable airbag between the driver and the steering wheel in the event of an emergency collision to protect the driver's safety. The airbag module mainly consists of parts such as the airbag, the housing, and the horn-activated mechanism. Currently, there are two common ways to activate the horn on the driver's side: one is to activate the horn through the multi-function button on the steering wheel, and the other is to activate the horn through the floating horn-activated mechanism of the airbag module itself. The horn-activated airbag module usually uses two connection structures between the horn-activated mechanism and the housing assembly: one is a threaded connection structure, and the other is a snap-fit ​​connection structure.

[0003] Currently, considering the issues of assembly accuracy and efficiency, existing technologies mostly use snap-fit ​​connections to fix the pressing mechanism.

[0004] A search revealed that Chinese utility model patent CN207818434U, authorized by the patent, discloses "a steering wheel horn switch structure, a steering wheel, and a vehicle," which includes a hook on the airbag module and a conductive strip exposed on the outer surface of the hook, a stationary contact on the steering wheel frame, a retaining spring, and an elastic body. The conductive strip corresponds to the stationary contact on the steering wheel frame; the retaining spring cooperates with the conductive strip; the steering wheel frame also has a groove corresponding to the hook, the elastic body is disposed in the groove, and the stationary contact is exposed on the outer surface of the elastic body. The entire airbag module and steering wheel frame are simple and ingeniously designed, and easy to manufacture, install, disassemble, and maintain.

[0005] The airbag pressing structure in the prior art, including the one mentioned above, is connected by several retaining rings. Although it can meet general usage requirements, the retaining rings need to be fixed and limited by bolts, which is cumbersome and has poor stability. The retaining rings are prone to detaching from the bolts, affecting the stability of the pressing mechanism installation.

[0051] Furthermore, by Figures 1-3 , Figures 8-10 As shown, in this embodiment, two No. 1 card holders 14 are symmetrically fixed to the steering wheel frame 1 and located in the non-pressing area, and each No. 1 card holder 14 has a hole. Two No. 1 card blocks 15 are symmetrically fixed to the fixing shell 3, and each No. 1 card block 15 is embedded in the hole of the No. 1 card holder 14 to form a locking structure. Two No. 1 Z-direction fixing hooks 16 are symmetrically fixed to the steering wheel frame 1 and located in the non-pressing area. Two No. 1 guide blocks 17 are symmetrically fixed to the fixing shell 3, and each No. 1 guide block 17 has a hole. Each No. 1 Z-direction fixing hook 16 is embedded in the hole of the No. 1 guide block 17. A No. 1 retaining spring 18 passes around the two No. 1 card holders 14 and through the No. 1 guide block 17, and the No. 1 retaining spring 18 is connected to the two No. 1 card holders 14. A first Z-axis fixing hook 16 engages with a second Z-axis fixing hook 19, which is fixed to the steering wheel frame 1 and located within the pressing area. A second guide block 20 is fixed to the fixed shell 3. One end of a second retaining spring 21 engages with the second guide block 20, and the other end engages with the second Z-axis fixing hook 19. With the above scheme, in use, the present invention achieves multi-point positioning and installation of the pressing mechanism 2 through the first retaining seat 14, the first retaining block 15, the first Z-axis fixing hook 16, the first guide block 17, the first retaining spring 18, the second Z-axis fixing hook 19, the second guide block 20, and the second retaining spring 21. This makes installation convenient, provides high stability, and extends the service life of the pressing mechanism 2.

[0052] Optionally, by Figures 1-7As shown in this embodiment, the pressing mechanism 2 further includes: a fixing ring 7, a horn plate 4, and a gas generator 5. The fixing ring 7 is fixed to the fixing shell 3 and has a central hole. The horn plate 4 is fixed on the fixing ring 7 and has two symmetrically distributed contact points 41. The gas generator 5 passes through the horn plate 4 and the fixing ring 7 and is fixed on the fixing ring 7. The outer wall of the gas generator 5 and the inner wall of the fixing ring 7 are connected to an airbag concealment groove 13 for placing an airbag.
