Description

Technical Field

[0002] The lumbar support and massage functions of a seat have become important considerations for seat comfort. The traditional solenoid valve pneumatic lumbar support massage system controls the opening or closing of the air circuit by generating electromagnetic force through the electromagnetic coil after power is applied. Since the components of each air circuit control are integrated in the valve body located at the interface, and there are many iron and copper parts in the valve body, the structure is complex and the weight is heavy. Chinese utility model patent CN212480225U discloses a pneumatically controlled massage control valve group and a multi-link pneumatic control unit, which uses a memory wire made of shape memory alloy. The shape memory alloy can shrink when powered on and heat, and return to its original shape after power is turned off and cooled. This property is used to make a memory wire. By powering and heating the memory wire, the bidirectional elastomer seal can be controlled to move up and down, thereby realizing the inflation and deflation of the air bag by the massage control valve group. However, the control valve group cannot maintain the pressure of the air bag, and therefore cannot realize the lumbar support function. Utility Model Content
