This mechanism addresses the low efficiency of existing screw-mounted airbag frame installations. The mechanism comprises a mounting base with a mounting cavity that mates with the airbag frame. The sidewalls of the mounting cavity are provided with a first retaining groove extending perpendicular to the depth of the cavity. The airbag frame is provided with a first retaining block and a first drive mechanism for rotating the first retaining block. When the airbag frame is properly installed, the first drive mechanism engages the first retaining block in the first retaining groove. However, this mechanism does not address the aforementioned issues. Utility Model Content

[0021] The following is a further detailed description of the specific implementation methods of the present invention through the description of the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0022] Figure 1 This is a structural diagram of the airbag frame instrument panel welding positioning structure in an embodiment of the present utility model; Figure 2 It is a schematic structural diagram of the airbag frame instrument panel welding positioning structure in the embodiment of the present utility model in the direction of the top view.

[0023] like Figure 1 As shown, the airbag frame instrument panel welding positioning structure provided by the present invention includes a first positioning structure 10 and / or a second positioning structure 20. The first positioning structure 10 is arranged between the airbag frame 1 and the instrument panel 2, and the second positioning structure 20 is arranged between the airbag frame 1 and the instrument panel 2. The first positioning structure 10 and the second positioning structure 20 can provide installation positioning and guidance when the airbag frame 1 is pre-installed, improve the installation accuracy between the airbag frame 1 and the instrument panel 2, and improve the positioning accuracy when the airbag frame 1 and the instrument panel 2 are welded, thereby improving product quality and improving the stability of the airbag frame.

[0024] Figure 3 It is a structural schematic diagram of the instrument panel in an embodiment of the present utility model; Figure 4 It is a structural schematic diagram of the airbag frame in an embodiment of the present utility model.

[0025] like Figure 3 and Figure 4As shown, the first positioning structure 10 includes a first positioning rib 11 provided on the instrument panel 2 and a first positioning groove 12 provided on the airbag frame 1. The first positioning rib 11 and the second positioning groove 12 are adapted to each other. During pre-installation, the first positioning rib 11 is locked in the second positioning groove 12. The second positioning structure 20 includes a second positioning rib 21 provided on the instrument panel 2 and a second positioning groove 22 provided on the airbag frame 1. The second positioning rib 21 is adapted to the first positioning groove 22. During pre-installation, the second positioning rib 21 is locked in the second positioning groove 22. The first positioning rib 11 and the second positioning rib 21 are respectively located on both sides of the instrument panel 2, and the first positioning groove 12 and the second positioning groove 22 are respectively located on both sides of the instrument panel 2. This allows the first positioning structure 10 to provide primary positioning for the installation of the airbag frame 1, and the second positioning structure 20 to provide secondary positioning for the installation of the airbag frame 1. The primary and secondary positioning cooperate with each other to improve the positioning accuracy of the airbag frame 1 installed on the instrument panel 2.

[0026] Figure 5 It is a structural schematic diagram of the first positioning groove in an embodiment of the present utility model.

[0027] like Figure 3 As shown, the first positioning rib 11 and the second positioning rib 21 are fin-shaped. The height of the first positioning rib 11 gradually increases perpendicular to the direction of the friction welding amplitude, and the height of the second positioning rib 21 gradually increases perpendicular to the direction of the friction welding amplitude, so as not to interfere with the amplitude of the friction welding and ensure the smooth progress of the friction welding. Figure 5 As shown, weakening grooves 13 are provided on both sides of the first positioning groove 12. The weakening grooves 13 are evenly distributed on both sides of the first positioning groove 12, so that the single-side gap between the first positioning rib 11 and the first positioning groove 12 is 0.1 mm, which can effectively improve the positioning accuracy of the main positioning.

[0028] During the process of connecting the airbag frame 1 and the instrument panel 2 by friction welding, the first positioning rib 11 melts in the first positioning groove 12 and the weakening groove 13, and the second positioning rib 21 melts in the second positioning groove 22, thereby connecting the airbag frame 1 and the instrument panel 2 by friction welding.
