The automobile is usually provided with a pressure release valve for exhausting the gas with excessive pressure in the automobile, thereby playing a role in adjusting the pressure difference between the inside and the outside of the automobile. When the pressure relief valve is used for pressure relief, the valve plate of the pressure relief valve is opened, so that high-pressure gas in the vehicle can smoothly flow out. However, since the valve plate of the relief valve is a low sound insulation material, noise outside the vehicle is easy to enter the vehicle through the relief valve, so that the noise inside the vehicle is increased, and the comfort of passengers is affected.

Referring to fig. 1, in order to solve the problem that the noise in the vehicle is increased due to the existing pressure release valve, a sound insulation pad assembly 100 is provided.
