Title:
AIRFLOW SENSING SEAT
Document Type and Number:
WIPO Patent Application WO/2021/068419
Kind Code:
A1
Abstract:
An airflow sensing seat comprises a seat body (1), an airbag (2), a sensing assembly (3), and a micro control unit (4). The airbag (2) is provided in the seat body (1). A deformable support structure (21) is provided in the airbag (2). The support structure (21) is used to maintain an appropriate amount of gas in the airbag (2). A transmission mechanism (5) is provided between the airbag (2) and the sensing assembly (3). The transmission mechanism (5) is used to transmit gas disturbance in the airbag (2) to the sensing assembly (3). The sensing assembly (3) is used to generate a corresponding analog electrical signal according to the gas disturbance. The sensing assembly (3) is electrically connected to the micro control unit (4). The sensing assembly (3) transmits the analog electrical signal to the micro control unit (4). The micro control unit (4) is used to perform analysis and computation on the analog electrical signal so as to acquire a biological signal of a user. The invention also relates to a method for adjusting a smart seat. The airflow sensing seat and an adjustment method therefor obviate the need to embed other electronic pressure sensing assemblies in the seat body, thereby avoiding damage to an electronic pressure sensing assembly due to frequent pressing thereon. In addition, the airbag does not need to be inflated during testing, thereby reducing costs.
