AIR CUSHION DEVICE AND WEIGHT CAPACITY SENSING METHOD

摘要

An air cushion device (10) comprises at least one pressure sensing air bag module (100). Each pressure sensing air bag module (100) comprises a pressure stabilizing air bag layer (110), a pressure equalizing air bag layer (120) and a pressure sensing layer (130). Wherein, the pressure equalizing air bag layer (120) is disposed on the pressure stabilizing air bag layer (110), and the pressure equalizing air bag layer (120) comprises multiple first cylindrical air bags (122) connected with each other and multiple second cylindrical air bags (124) connected with each other. The first cylindrical air bags (122) and the second cylindrical air bags (124) are stood on the pressure stabilizing air bag layer (110) and arranged into an array. The pressure sensing layer (130) is disposed between the pressure stabilizing air bag layer (110) and the pressure equalizing air bag layer (120) so as to sense the pressure which the multiple parts of the pressure equalizing air bag layer (120) bear. A weight capacity sensing method using the air cushion device is also included.
