Vehicle air extraction system and method

摘要

An automotive vehicle air extraction system in fluid communication with a cabin of the vehicle is provided. The extraction system may have a housing arrangement and a pair of extractors attached to the housing arrangement. A chamber may be formed between the housing arrangement and pair of extractors. An air pump may be in fluid communication with the chamber. The pair of extractors may be an inner extractor and an outer extractor. A controller may be configured to activate the air pump to supply airflow to the chamber to close the inner extractor and/or prevent inadvertent opening of the inner extractor.

1. A system for preventing fluid ingress to a vehicle cabin comprising:
a housing including an inner one-way valve opening to the cabin, an outer one-way valve opening to a vehicle exterior and located proximate the inner one-way valve defining a chamber there between, an inlet port and an air baffle proximal the inlet port: and an air pump in fluid communication with a chamber, the air pump activated by a controller to supply airflow to the chamber via the inlet port in response to sensing a predetermined condition, wherein airflow from the inlet port flows in a first direction and impinges on the air baffle, redirecting the airflow in a second direction orthogonal to the first direction and onto the inner one-way valve to prevent opening of the inner one-way valve.
