The control board 3 is provided with an electrical interface 31. The cover 11 and the housing 12 together define a second through hole 15. The second through hole 15 is used to accommodate the electrical interface 31, so that the electrical interface 31 can be exposed to the outside of the housing 1 through the second through hole 15.

[0094] It is understandable that by setting the second through hole 15 to be defined by the cover 11 and the housing 12, the molding difficulty of the second through hole 15 can be reduced, and the electrical interface 31 can be easily installed into the second through hole 15, thereby reducing the installation difficulty and improving the design rationality of the air pump assembly 100.

[0095] In some embodiments of this utility model, such as Figure 1 As shown, the housing 1 is also provided with a stop rib 16, which protrudes from the surface of the housing 1 and surrounds the second through hole 15. The stop rib 16 is used to protect the electrical interface 31 to ensure the connection stability between the electrical interface 31 and the domain control vehicle wiring harness. This can improve the reliability of the air pump assembly 100.

[0096] The utility model also provides a vehicle seat device.

[0097] The vehicle seat device according to the utility model embodiment, at least one of the side wing and the waist support is communicated with the air outlet pipe 71.

[0098] The vehicle seat device according to the utility model embodiment, the response speed block of the waist support and the side wing, meet the design requirement, improve the overall performance of vehicle seat device.
