Embodiment 1
[0035] Figure 1 to Figure 7 A first embodiment of the invention is shown in which, figure 1 is a structural schematic diagram of the first structure of the present invention; figure 2 Yes figure 1 The structural diagram of the intelligent dual power transfer switch shown when viewed from another angle; image 3 Yes figure 1 A schematic diagram of a three-dimensional structure of the permanent magnet drive mechanism in the intelligent dual power transfer switch shown; Figure 4 Yes image 3 The schematic diagram of the structure of the permanent magnet drive mechanism when viewed from the direction of the front cover; Figure 5 Yes Figure 4 Sectional view along line A-A; Image 6 Yes image 3 A schematic diagram of a three-dimensional structure of the permanent magnet drive mechanism shown after removing the front cover; Figure 7 Yes image 3 A schematic diagram of a half-section structure of the permanent magnet drive mechanism shown after removing the permanent ...
Embodiment 2
[0047] Figure 8 It is a half-sectional structural schematic diagram of the permanent magnet drive mechanism used in the second structure of the present invention after the permanent magnet is removed, showing the second embodiment of the present invention.
[0048] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 8 , the arrangement of the permanent magnets is different. In this embodiment, the inner wall of the housing 62 is provided with an annular groove 100 for limiting the permanent magnet 67 , and the permanent magnet 67 is disposed in the groove 100 . This structure enables the adjusting bolt to limit the yoke ring and at the same time limit the permanent magnet to avoid loosening and displacement due to vibration.
Embodiment 3
[0050] Figure 9 It is a schematic diagram of the half-section structure of the permanent magnet drive mechanism used in the third structure of the present invention after removing the permanent magnet, showing the third embodiment of the present invention.
[0051] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 9 , the arrangement of the permanent magnets is different. In this embodiment, the outer wall of the yoke ring 68 is provided with an annular groove 100 for limiting the permanent magnet 67 , and the permanent magnet 67 is disposed in the groove 100 . This structure enables the adjusting bolt to limit the yoke ring and at the same time limit the permanent magnet to avoid loosening and displacement due to vibration.
