Description

Air inlet structure assembly and vehicle

Technical Field

The utility model belongs to the technical field of vehicle parts, and particularly relates to an air inlet structure assembly and a vehicle.

Background

The main function of the air inlet system is to convey clean, dry, sufficient and stable air for the engine so as to meet the requirements of the engine and avoid abnormal abrasion of the engine caused by the fact that impurities and large-particle dust in the air enter the combustion chamber of the engine. Noise and vibration are generated during the air intake process, and energy of the noise and vibration is transmitted into the vehicle to affect NVH performance of the vehicle, so noise reduction of the air intake system is an important subject in the design process of the air intake system. The existing noise reduction mode mainly comprises the steps of adding a muffler, and dissipating noise energy through the sound absorption and resonance characteristics of the muffler; the vibration attenuation effect is realized mainly by increasing or decreasing the rigidity of the structure and increasing the damping of the system, so that on one hand, the resonance frequency is avoided, and on the other hand, the vibration energy is dissipated through the damping of the system. Generally, existing noise reduction means are mainly the conversion of acoustic energy to thermal energy and the conversion of vibrational energy to thermal energy. However, the conventional noise reduction method does not consider recycling of acoustic energy and vibration energy in many cases.
