[0005] By adopting the above technical scheme, a mounting ring is provided, and the mounting ring is used to be fixed to the interior panel of the automobile. The cavity is installed and connected to the mounting ring through the first damping rod.

Since the mounting ring is fixedly installed on the interior panel of the automobile, and the cavity is installed on the mounting plate through the first damping rod, shaking is likely to occur between the cavity and the cover plate. Therefore, an elastic airbag is provided on the cover body. When the cavity moves, the first damping rod will swing, thereby driving the rotating ball to rotate, and then the connecting component drives the inflation component to inflate the elastic airbag. The elastic airbag is further expanded, thereby improving the connection stability between the cover body and the interior panel.

[0012] Optionally, each guide block is provided with two guide surfaces, and the two guide surfaces are symmetrically arranged so that the two guide surfaces form a V-shaped groove.

[0013] By adopting the above technical solution, since the movement of the cavity in any direction has two positive and negative movement trajectories, the first connecting rod can rotate clockwise and counterclockwise.

The elastic airbag is further expanded, thereby improving the connection stability between the cover body and the interior panel. The elastic airbag is an elastic part and will not cause resonance between the audio system and the car interior panel. BRIEF DESCRIPTION OF THE DRAWINGS
