The invention discloses an air bag self-adaptive adjusting seat which is characterized in that an air bag is arranged on a backrest or/and a cushion, the air bag is inflated or deflated through an air pump, and the air pump is controlled through a control module; a sensing unit or a part of the sensing unit is arranged on the face, facing a passenger, of each air bag, the control module comprises an MCU module and a plurality of mutually independent oscillating circuits connected with the MCU module, and each oscillating circuit is electrically connected with one sensing unit; when a passenger makes contact with or applies pressure to any sensing unit, the charging and discharging frequency of the oscillating circuit connected with the sensing unit can be changed, the MCU module detects the change of the charging and discharging frequency before and after the oscillating circuit makes contact with or applies pressure to obtain a passenger contact pressure value, and the MCU module determines the passenger contact pressure value according to the detected passenger contact pressure value. An instruction is output through logical operation, and the air pump is controlled to conduct inflation or deflation adjustment on the air bag. The invention further discloses an air bag self-adaptive adjusting method.
本发明公开了一种气袋自适应调节座椅,在靠背或/和坐垫上布置有气袋,气袋的充气或者放气行为通过气泵来实现,气泵通过控制模块控制;其在每一气袋朝向乘员的一面设置有传感单元或者传感单元的一部分,控制模块包括MCU模块和与MCU模块连接的若干条相互独立的振荡电路,每一振荡电路与一个传感单元电连接;当乘员接触或施压任一传感单元时,会使得与该传感单元连接的振荡电路的充放电频率发生变化,MCU模块检测该振荡电路接触或施压前后的充放电频率的变化,即可得到乘员接触压力值,MCU模块依据所检测的乘员接触压力值,通过逻辑运算输出指令,控制气泵对气袋进行充气或者放气调节。本发明还公开了一种气袋自适应调节方法。
