The invention discloses a vehicle intake silencing structure. The vehicle intake silencing structure comprises a low-frequency resonant cavity fixed on the wall of an air inlet pipe, and further comprises a high-frequency resonant cavity positioned in the low-frequency resonant cavity and fixed on the wall of the air inlet pipe, and a silencing pipe, wherein a through hole is formed in the connected place between the wall of the air inlet pipe and the high-frequency resonant cavity; one end of the silencing pipe is communicated with the air inlet pipe through the through hole, and the other end penetrates outside the high-frequency resonant cavity to be communicated with the low-frequency resonant cavity; and multiple through holes are formed in the wall, positioned in the high-frequency resonant cavity, of the silencing pipe. The vehicle intake structure not only can solve the problem of intake low-frequency noise generated in the starting of a supercharged engine, bit also can solve the problem of high-frequency noise generated in the acceleration process of the supercharged engine. Meanwhile, the vehicle intake silencing structure reduces the manufacturing cost, and is convenient to arrange a cabin without losing beauty.
