Description

Technical Field

[0001] The utility model belongs to the technical field of automobile seats, in particular to a seat structure with air suction function and a vehicle. Background Art

[0002] At present, as passengers' requirements for in-car comfort increase, some cars' rear seats are required to have ventilation functions, and most of them are suction functions. Air is sucked from the A side of the seat, that is, from the cab, and introduced into the trunk to meet the passengers' cooling needs. It can also prevent the odor generated by the trunk due to complicated storage such as shoes, fish, etc. from being introduced into the cab.

[0003] However, the space between the backrest A side and the back of the seat is usually limited; the frame is a back plate structure and a platform part, which cannot be changed; and in order to achieve the air suction function, the fan blade side must be connected to the foam air duct side facing the foam B side, and cannot be directly bonded to the foam. How to place and fix the fan with ventilation function and how to achieve the sealing of the ventilation system are technical problems that must be solved. Summary of the invention

[0004] The utility model provides a seat structure and a vehicle with an air suction function, which solves the problems of fixing the fan and sealing the air inlet and outlet channels by designing a ventilation system cover and a sealing ring structure embedded in the foam B surface, without changing the backrest frame to fix the fan and increasing the space requirement between the foam A surface and the back plate frame.
