5 and FIG. 6, wherein FIG. 5 shows a schematic view of the magnetic drive unit 2 according to another embodiment of the present invention, and FIG. 6 shows a cross-sectional view of the magnetic drive unit 2 of FIG. It should be understood that the difference between the magnetic driving device 2 of the present embodiment and the magnetic driving device 1 (FIG. 1) of the foregoing embodiment is that the plurality of fixing units 10 and the rotating unit 20 (for example, 4) are further connected in series. The fixing unit 10 and the rotating unit 20, but the invention is not limited thereto, wherein the number of the fixing unit 10 and the rotating unit 20 connected in series may be determined as needed. Specifically, in the embodiment, the plurality of fixing units 10 can be locked together by a plurality of locking members P and fixed on opposite sides of a stationary base S, and the plurality of rotating units 20 have a common The rotating shaft 200 and the positions of the rotating unit 20 correspond to the fixed unit 10, respectively. Thereby, the magnetic drive device 2 of the present embodiment includes a plurality of sets of magnetic drive assemblies (the fixed unit 10 and the rotary unit 20), so that a larger rotational moment can be generated to drive the rotary base 202 of the rotary unit 20 and the rotary shaft 200 to rotate.

The magnitude of the repulsive force between the first magnet 102 of the 10 and the second magnet 204 of the rotating unit 20 controls even the magnetic force of the magnetic drive unit 2 to drive the switch.

For example, when the magnetic driving device 2 is in the state shown in FIGS. 5 and 6, the distance between the first magnet 102 of the fixing unit 10 and the second magnet 204 of the rotating unit 20 is large, resulting in the first The repulsive force between the second magnets 102 and 204 is small, and the rotation of the rotating base 202 and the rotating shaft 200 cannot be driven (that is, the magnetic driving of the magnetic drive device 2 is in an OFF state); and when the aforementioned adjusting member T is received When an external force acts to rotate along the circumference of the fixed disc 100 (as indicated by the arrow in FIG. 5), the spacing D between the first portion 100B and the second portion 100C can be adjusted (eg, enlarged) so that the fixing is fixed. The distance between the first magnet 102 of the unit 10 and the second magnet 204 of the rotating unit 20 can be made small, and the repulsive force between the first and second magnets 102 and 204 is thereby increased, thereby driving the rotating base 202 and the rotating shaft 200.

It should be understood that the difference between the magnetic drive device 2' (Figs. 7 and 8) of the present embodiment and the magnetic drive device 2 (Fig. 5) of the foregoing embodiment is that two pairs on one side of the base S are The fixing unit 10, 10' and the first magnet 102 and the second magnet 204 in the rotating unit 20, 20' are arranged oppositely (relatively, in the magnetic driving device 2 of Fig. 5, located at the base S Two pairs of fixed units 10 on one side The arrangement of the first magnet 102 and the second magnet 204 in the moving unit 20 is the same). Specifically, in the present embodiment, the first and second magnetic pole faces 102A and 204A of the fixed unit 10 (closer to the base S) and the corresponding rotating unit 20 are both N poles and are located above. The first and second magnetic pole faces 102A and 204A of the fixing unit 10' (relative to the base S) corresponding to the rotating unit 20' are both S poles.

The magnets 102 and 204, and the first and second magnets 102 and 204 located below correspond to the first and second magnets 102 and 204 in the fixed unit 10 and the rotating unit 20 in FIG.

In addition, when the aforementioned adjustment member T (refer to FIG. 7) is subjected to an external force to rotate around the fixed disc 100 of the upper fixed unit 10' (which is farther away from the base S), and is fixed at the upper side The distance between the unit 10' (i.e., the fixed unit located between the two rotating units 20 and 20') and the first magnet 102 and the second magnet 204 in the rotating unit 20' becomes larger (as in the right portion of Fig. 8) As shown, the repulsive force between the first and second magnets 102 and 204 can be made small, and the rotating base 202 and the rotating shaft 200 cannot be driven to continue to rotate (that is, the magnetic driving of the magnetic driving device 2' is turned off (OFF). status). It is worth mentioning that the first magnet 102 and the second magnet in the above-mentioned fixed unit 10' and the rotating unit 20' When the distance between the 204s becomes larger, the distance between the first magnet 102 and the second magnet 204 of the rotating unit 20 (below the base S) is relatively small, and an attractive force can be generated.
