Problems solved by technology

This type of limit relief valve is bulky, costly, and has a high failure rate, so it is not suitable for arrangement in a narrow space environment
[0005] At the same time, the pneumatic system of such vehicle seats usually adopts noise reduction methods such as air pumps, pneumatic valve groups and pipelines with noise-absorbing coatings, noise-absorbing shells, etc., which have poor noise reduction effects, large volume, and difficult installation Disadvantages such as layout

Embodiment 1

[0035] Please refer to figure 1 A micro-air pump for a vehicle provided in this embodiment includes a pump body and an air distribution layer 3 communicating with the pump body. The air distribution layer 3 is provided with at least one device for communicating with an air device The gas supply port 4 of the gas distribution layer part 3 is provided with at least one overflow hole 10, and one end of the overflow hole 10 communicates with the gas in the gas distribution layer part 3 and the pump body part, and the overflow The other end of the hole 10 communicates with the outside atmosphere.

[0036] Specifically, the gas distribution layer part 3 has a cavity inside, and the overflow hole 10 can be opened at any position communicating with the cavity. Further, it can be set on the air distribution layer part 3 and away from the air supply port 4, such as image 3 As shown; it can be set on the gas distribution layer part 3 and close to the air supply port 3, such as figur...

Embodiment 2

[0065] This embodiment provides a pneumatic adjustment system for a car seat, which includes the micro-air pump for a car with the structure described above, and also includes at least one air bag and a connecting pipeline.

[0066] Specifically, the pneumatic adjustment system is used for vehicle seats, and may also be used for furniture seats; the pneumatic adjustment system includes a pneumatic support system and / or a pneumatic massage system.

[0067] Since the pneumatic adjustment system includes the micro-air pump for vehicles with the above structure, the pneumatic adjustment system can avoid the surge of the air pressure and prevent the large noise caused by the fluctuation of the air pressure.

Abstract

The invention provides an automotive miniature air pump and a pneumatic adjusting system for an automobile seat. The automotive miniature air pump comprises a pump body part and an air distribution layer part communicated with the pump body part, the air distribution layer part is provided with at least one air supply port used for being communicated with an air using device, the air distribution layer part is provided with at least one overflow hole, one end of the overflow hole is communicated with gas in the air distribution layer part and the pump body part, and the other end of the overflow hole is communicated with the outside atmosphere. According to the automotive miniature air pump, output air pressure is uniform, air pressure fluctuation can be avoided, and noise is low.

Description

technical field [0001] The present disclosure generally relates to the technical field of air pumps, in particular to a micro-air pump for vehicles and a pneumatic adjustment system for car seats. Background technique [0002] The micro-air pump for vehicles is usually a micro-piston type air pump in which the motor drives the rubber tile valve chamber to cycle. When it operates, the motor will drive each leather tile valve chamber to squeeze out air in turn every time the motor rotates one circle. The output air flow is output in the pipeline in the form of surge and pulsation. At this time, the airflow output by the air pump is often affected by intermittent airflow surges, causing surge noise in the output pipeline. When the output airflow of the air pump is inflated to the external pneumatic components (airbag body, cylinder, etc.) through the control of the pneumatic valve group, it is also easy to produce abnormal sound caused by uneven and fluctuating air pressure. ...
