AI Technical Summary
Existing airbag structures have shortcomings in terms of comfort and size. Traditional single-cavity single-tube airbags have poor fit, while multi-cavity multi-tube airbag devices are bulky and require complex electronic control systems. TPU material is too hard, which affects long-term wearing comfort.
It adopts a three-layer composite multi-chamber airbag, with an outer layer of low-elasticity material and an inner layer of soft, high-elasticity material. The main air supply line is controlled by a solenoid valve and each inflation chamber is controlled by a segmented air valve, so as to achieve accurate control of zoned air pressure and air pressure gradient.
It improves the fit and comfort of the airbag to the human body, and enables individual control of each inflation chamber, making it suitable for lightweight wearable medical devices.
