Problems solved by technology

[0002] With the development of science and technology, people have higher and higher requirements for the comfort of car seats. Car seats usually have the functions of adjusting posture and shape, seat surface support, and seat surface massage. The combined pneumatic control of the pneumatic cavity (the pneumatic adjustment control device of the vehicle seat); but in the prior art, the pneumatic control mechanism of the complicated solenoid valve coil is usually used, which has the advantages of low life, inconvenient use, and inconvenient maintenance, etc. defect

Abstract

A pneumatic control valve device comprises an internal hollow valve body, an elastic assembly and an electric control module. The valve body is provided with an air inlet channel, an inflation channeland an air release channel which communicate with the outside, and a one-way valve is arranged in the air inlet channel. The air inlet channel is used for introducing air, and the inflation channel is used for supplying air to a pneumatic cavity. The elastic assembly is arranged at the end, communicating with the outside, of the air release channel. The electric control module comprises a circuitboard, an elastic first electrode and a memory alloy wire connected with the first electrode. One end of the first electrode is connected with the elastic assembly, and the other end of the first electrode is electrically connected with the circuit board. The end, far away from the first electrode, of the memory alloy wire is electrically connected with the circuit board. The electric control module is used for controlling the elastic assembly to close or open the air release channel.

Description

technical field [0001] The present disclosure generally relates to the technical field of automobile seats, and specifically relates to a pneumatic control valve device, a pneumatic control valve group and a pneumatic control assembly. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the comfort of car seats. Car seats usually have the functions of adjusting posture and shape, seat surface support, and seat surface massage. The combined pneumatic control of the pneumatic cavity (the pneumatic adjustment control device of the vehicle seat); but in the prior art, the pneumatic control mechanism of the complicated solenoid valve coil is usually used, which has the advantages of low life, inconvenient use, and inconvenient maintenance, etc. defect. Contents of the invention [0003] In view of the above defects or deficiencies in the prior art, it is desired to provide a pneumatic control valve device...
