The invention discloses a memory alloy pneumatic control valve body structure, a pneumatic valve group and a controller assembly, and relates to the technical field of vehicles. An accommodating space is formed between the bottom cover and the shell; a first air port communicated with the accommodating space is formed in the shell; the valve core is arranged in the accommodating space; one end of the valve core corresponds to the first air port, and the other end penetrates through the bottom cover and can move relative to the bottom cover; the valve element is sleeved with the elastic element, the end, close to the first air opening, of the elastic element is connected with the valve element, and the end, away from the first air opening, of the elastic element abuts against the bottom cover; the sealing piece is arranged on one side, close to the first air port, of the bottom cover; the sealing piece comprises a flat gasket and a protruding structure connected with the flat gasket, and the flat gasket is connected with the bottom cover. The protruding structure is an annular umbrella-shaped structure extending in the direction away from the bottom cover, and the end, away from the bottom cover, of the protruding structure is arranged on the valve element in a sleeving mode. The structure reliability is improved, and the air path state of the valve body structure is prevented from being affected by external environment temperature.
本申请公开记忆合金气动控制阀体结构、气动阀组以及控制器总成,涉及车辆技术领域,该结构包括:底盖,其上罩设有外壳;底盖与外壳之间形成容纳空间;外壳上开设有与容纳空间连通的第一气口;阀芯,其设置在容纳空间内;阀芯一端和第一气口对应设置,另一端贯穿底盖且能够相对底盖移动;弹性元件,其套设在阀芯上,弹性元件靠近第一气口的一端和阀芯连接,弹性元件远离第一气口的一端和底盖相抵;密封件,设于底盖靠近第一气口一侧;密封件包括:平垫和与平垫连接的凸起结构,平垫与底盖连接;凸起结构为沿远离底盖的方向延伸的环形伞状结构,凸起结构远离底盖一端套设于阀芯上;提高结构可靠性,避免阀体结构的气路状态受到外部环境温度影响。
