DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be further described in detail below with reference to the drawings and through embodiments. The following embodiments are explanations of the present utility model and the present utility model is not limited to the following embodiments.

[0024] Embodiment

[0025] See Figures 4-9 , in this embodiment, the relay magnetic steel structure mainly includes a magnetic steel member 1, an armature 1 2, and an armature 2 3. The magnetic steel member 1 is provided with two magnetic poles with fixed polarities, namely magnetic pole 1 4 and magnetic pole 2 5. The polarities of magnetic pole 1 4 and magnetic pole 2 5 are opposite. Assuming that the polarity of magnetic pole 1 4 is the N pole and the polarity of magnetic pole 2 5 is the S pole.

[0026] In this embodiment, the armature 1 2 is fixedly connected to the magnetic pole 1 4 of the magnetic steel member 1, and the armature 2 3 is fixedly connected to the magnetic pole 2 5 of the magnetic steel member 1; the polarities of the armature 1 2 and the armature 2 3 are opposite.

[0027] In this embodiment, the projections of the armature 1 2 and the armature 2 3 on the first projection plane perpendicular to the Z-axis intersect with each other, and the intersecting part 6 of the armature 1 2 and the armature 2 3 forms a gap H along the Z-axis direction.

[0028] In this embodiment, the armature 1 2 is respectively provided with a suction 1 21 and a suction 2 22 on both sides along the Y-axis direction, and the armature 2 3 is respectively provided with a suction 3 31 and a suction 4 32 on both sides along the Y-axis direction.

[0029] In this embodiment, a notch 23 is formed on the armature 1 2, and the notch 23 is used for the avoidance of the installation of the armature 2 3.

[0030] Specific working cooperation process: Initially, in Figure 8 state, a positive current is applied to the coil 7, and a magnetic field is generated through the yoke 8. The polarity of the magnetic field is Figure 8 with the S pole on the right and the N pole on the left. When the generated magnetic force is greater than the magnetic force generated by the original magnet, like poles repel each other, and the magnetic steel member 1 starts to move in the -X direction. During the movement, the distance between the upper magnetic pole of the magnetic steel member 1 and the yoke is decreasing. Since the polarities of the upper magnetic pole of the magnetic steel member 1 and the yoke are exactly opposite, the magnetic force of the magnetic steel is superimposed at this time, accelerating the movement of the magnetic steel assembly in the -X direction, and finally forming Figure 9 state. At this time, the current applied to the coil 7 also stops, and the state of the magnetic steel member 1 is maintained by the magnetic force generated by the permanent magnet. Conversely, from Figure 9 state to Figure 8 state, only by applying a current to the coil 7 that is opposite to the previous one can it be achieved.
