Abstract
The utility model discloses an air inlet assembly of a vehicle. The air inlet assembly of the vehicle comprises an air inlet duct upper body and an air inlet duct lower body which are connected together. The air inlet duct upper body comprises an air inlet cavity, a resonant cavity and a through hole, wherein the air inlet cavity and the resonant cavity are formed in an integrated mode, and the through hole communicates the air inlet cavity with the resonant cavity. An air inlet and an air outlet port are formed in the positions, located in the air inlet cavity, on the air inlet duct upper body, and the air outlet port is communicated with the air inlet duct lower body. By the adoption of the air inlet duct assembly, air enters the air inlet cavity through the air inlet and eventually flows into the air inlet duct lower body through the air outlet port, in the process of transmitting noise to the air inlet from the air inlet cavity, resonance sound waves are generated when the noise passes through the resonant cavity, the noise is attenuated, and therefore air inlet noise is reduced.
