The invention relates to an electromagnetic adsorption butt joint structure for a microgravity environment and application thereof, the butt joint structure comprises an armature component and an electromagnetic component, the armature component comprises a first annular magnetic circuit and two guide iron cores symmetrically distributed at the front end of the first annular magnetic circuit, and each guide iron core comprises an electromagnetic guide rod; the electromagnetic component comprises a second annular magnetic circuit and two electromagnetic coils which are symmetrically distributed at the front end of the second annular magnetic circuit and are opposite in polarity, a guide iron core is further fixed in each electromagnetic coil, and a guide pin hole is formed in each guide iron core; the front end of the guide iron core extends out of the electromagnetic coil, and a guide groove used for guiding the electromagnetic guide rod to enter the guide pin hole is formed in the front end face of the guide iron core. The device is simple in structure, easy to implement and small in size; the adsorption distance can be adjusted and the butt joint force can be controlled by controlling the magnitude of current in the electromagnetic coil; the electromagnetic force directly acts on the armature, and the directivity is good; in cooperation with a guide structure, the complexity of butt joint parts is reduced, and the device is suitable for being used in a microgravity environment.

    本发明关于一种用于微重力环境的电磁吸附对接结构及其应用,该对接结构包括衔铁部件和电磁部件,衔铁部件包括第一环状磁路和对称分布在该第一环状磁路前端的两个导向铁芯,导向铁芯包括和电磁导杆;电磁部件包括第二环状磁路和对称分布在该第二环状磁路前端的两个极性相反的电磁线圈,且每个电磁线圈内还固定一个导向铁芯,该导向铁芯内具有导销孔,且该导向铁芯前端伸出电磁线圈并在前端面上形成用于引导电磁导杆进入导销孔内的导向槽。本发明结构简单,易于实现,尺寸体积小;通过控制电磁线圈中的电流大小,即可调节吸附距离,控制对接力;电磁力直接作用于衔铁,方向性好;配合引导结构,降低了对接部件的复杂度,适合微重力环境使用。
