Description

Pneumatic massage utricule, pneumatic massage system and car seat

Technical Field

The present disclosure generally relates to the field of automotive pneumatic massage technologies, and in particular, to a pneumatic massage capsule, a pneumatic massage system, and an automotive seat.

Background

In the prior art, when a pneumatic massage system of a vehicle seat is inflated, air flow output by an air source body inflates an air bag body through an air path control valve group. The air flow passes through the pneumatic port in the control valve, is connected with the air pipe and is input into the pneumatic air bag body, and is gradually filled. At the moment, the high-speed airflow of the air source body is output to the air pipeline through the pneumatic port of the pneumatic valve body; the high-speed air flow in the air pipeline continuously inflates the massage bag body through the air pipe and the pipeline interface. The air flow, the side wall of the pipeline, the inner wall of the pipeline interface and the pipeline air port entering the massage bag body can generate flow speed friction, and the pneumatic resonance and noise of the air pipeline surge type can be easily generated. Meanwhile, when the air bag body of the pneumatic system is deflated to act, the airflow flows through the opposite pipelines and is discharged outwards through the pipeline air ports of the pneumatic bag body; at this time, the pipeline air port, the pipeline side wall and the pipeline interface inner wall can also generate pneumatic resonance and noise. Because the space in the vehicle is relatively narrow, particularly, the number of quieter vehicles such as pure electric vehicles is increased, and passengers are more sensitive to noise.

Although the effect of sealing and isolating noise can be achieved by using surface attachments such as felt-mat type coverings and sound-deadening sheaths. However, since the massage airbag body is generally laid on the sponge pad in the seat cover facing the human body side of the occupant, the surface attachment is liable to cause unevenness and a foreign body feeling of the seat.
