AI Technical Summary
Existing car seat air pump systems suffer from severe noise problems. Traditional methods include adding sound insulation cotton to wrap the air pipe or installing an independent sound insulation cover on the outside of the air pump for passive noise reduction. The single-walled smooth air pipe structure 5 causes frequent abrupt changes in the cross-sectional area of the airflow channel, resulting in turbulent noise due to airflow friction. The short air intake path design inside the air pump housing causes the airflow to directly enter the air pump cavity, resulting in superimposed vibration noise and affecting passenger comfort.
The noise-reducing air pipe adopts a multi-layer hollow structure, and a fixed sealing sleeve is provided at the connection between the air pump housing and the air pipe. The airflow path is extended and layered, and the airflow is damped by different media. The auxiliary air inlet enhances the stability of the air volume.
It effectively reduces airflow pulse frequency and turbulence noise, improves airflow stability and intake volume, and enhances the noise control and power output capabilities of automotive seat pneumatic systems.
