The two core portions 1211 and the conductive members 1213 may be integrally connected or detachably connected, and each of the first magnetic conductive units 121 may be fixed to the flow tube 111 of the housing 11 through the core portion 1211 thereof. Each of the cores 1211 described above defines a centerline C that is substantially perpendicular to the axis L.

The number of the soft magnetic conductive brushes 122 is substantially equal to the number of the core portions 1211 in the first magnetic conductive module 12, so that each of the core portions 1211 is provided with a soft magnetic conductive brush 122, that is, The soft magnetic conductive brushes 122 are respectively mounted on the ends of the core portions 1211 away from the flow tube 111 of the housing 11, and the soft magnetic conductive brushes 122 are located in the flow passage 113.

Referring to FIG. 2 and FIG. 3, the rotor assembly 2 is rotatably disposed on the shell. The rotor assembly 2 includes a rotating member 21 that is rotatable about the axis L and a first magnetic module 22 that is mounted on the rotating member 21. The rotating member 21 includes a cylinder 211 and a spiral blade 212 connected to the outer edge of the cylinder 211. The two ends of the cylinder 211 are respectively pivoted at the center of the two supporting portions 112 of the housing 11, and the column The center line of the body 211 overlaps with the above-described axis L in this embodiment. The edge of the spiral blade 212 is recessed in a radial direction of the vertical axis L to form at least one receiving groove 2121 (the radial direction is parallel to the center line C). Moreover, the distance of the edge of the helical blade 212 relative to the axis L is greater than the minimum distance of the soft magnetically permeable brush 122 relative to the axis L (ie, the distance between the free ends of the flexible metal wires and the axis L).

In addition, the rotating member 21 shown in FIG. 3 is exemplified by a single spiral blade 212 formed on the cylinder 211, but the embodiment can also be adjusted and changed according to requirements. For example, as shown in FIG. 4, the rotating member 21 of the present embodiment may be formed with a plurality of spiral blades 212 on its cylinder 211, and each of the spiral blades 212 may be in a specific position as required by the designer. A receiving groove 2121 is formed for the corresponding first magnetic module 22 to be disposed. Moreover, although the rotating member 21 is exemplified by the provision of the spiral blade 212, it is not excluded that the rotating member 21 is changed to a non-helical blade like a fan blade (not shown) or is used like a conventional generator or motor. Disc structure (figure omitted).

Referring to FIG. 5 , the first magnetic module 22 includes two permanent magnets 221 (eg, magnets) and a long strip of magnetic conductors 222 (eg, metal materials, silicon steel sheets, or iron blocks). And two position adjustment unit 223. The two position adjusting units 223 are respectively disposed in the two accommodating grooves 2121, and the two magnets 221 are respectively located in the two accommodating grooves 2121 and are respectively installed in the two position adjusting units 223. The magnetic conductor 222 is embedded in the spiral blade 212, and the two magnets 221 abut against opposite ends of the magnetic conductor 222, respectively. Moreover, the opposite end edges of the magnetic conductor 222 are preferably respectively aligned with the side edges of the two magnets 221 away from each other, so that the magnetic force can be completely transmitted, but not limited thereto.

It should be noted that one end of the two magnets 221 away from the cylinder 211 is defined as two magnetic poles 2211, respectively, and the first magnetic module 22 can respectively emit magnetic magnetic differences via the two magnetic pole ends 2211 (for example: FIG. 5 The magnetic magnet 221 on the left side is N pole, the right magnet 221 is S pole on the top, and the magnetic force generated by one of the magnets 221 is transmitted to the other magnet 221 via the magnetic conductor 222.

The position adjustment unit 223 includes a spring 2231, a fixed frame 2232, and a movable frame 2233 in this embodiment, but does not exclude the replacement of some components or other components. Furthermore, the spring 2231 may be a compression spring or a tension spring, or be replaced by other resilient members.

In more detail, viewed from one of the magnets 221 and its corresponding position adjusting unit 223 (as shown in FIGS. 5 and 6), the fixed frame 2232 and the movable frame 2233 each have a tubular portion 2232a, 2233a and a tubular portion thereof. The side portions 2232a and 2233b of the end portions 2232a and 2233a extend outwardly perpendicularly. The fixing frame 2232 is fixed at the top of the accommodating groove 2121 by the flank portion 2232b thereof, and has a gap G between the outer surface of the tubular portion 2232a and the side wall of the accommodating groove 2121. The magnet 221 is mounted on the inner side of the tubular portion 2233a of the movable frame 2233, and the tubular portion 2233a of the movable frame 2233 is movably disposed in the tubular portion 2232a of the fixed frame 2232, and the side flap portion 2233b of the movable frame 2233 is adjacently disposed. The groove of the groove 2121 is accommodated. Thereby, through the above arrangement, the movable frame 2233 has only one degree of freedom corresponding to the fixed frame 2232.

Furthermore, the spring 2231 is disposed on the gap G formed between the outer surface of the tubular portion 2232a of the fixed frame 2232 and the side wall of the receiving groove 2121, and the opposite ends of the spring 2231 (such as the top end and the bottom end of the spring 2231 in FIG. 5) The abutting portion 2232b of the fixed frame 2232 and the side wing portion 2233b of the movable frame 2233 are respectively abutted so that the spring 2231 can be deformed when the magnet 221 is subjected to a force (such as the following centrifugal force). The deformed spring 2231 tends to return the magnet 221 (or the movable frame 2233) to the position before the displacement, so that the movable frame 2233 can transmit the centrifugal force and the spring 2231. With force, it reciprocates relative to the fixed frame 2232 (or the magnetic conductor 222).

The above is the configuration of the stator assembly 1 and the rotor assembly 2 of the present embodiment. The following describes the operational flow between the stator assembly 1 and the rotor assembly 2 and the corresponding relationship between them.

Referring to FIG. 5, when the rotating member 21 is stationary, the magnet 221 and the movable frame 2233 are located on the bottom of the receiving groove 2121. At this time, the magnet 221 is opposite to the rotating member 21 (or its receiving groove 2121. The position is defined as a first position (as shown in Figure 5).

When a fluid (such as a wind) outside the power generating device 100 enters the flow passage 113 of the casing 11 to apply a driving force to the spiral blade 212 of the rotating member 21, the rotating member 21 will rotate about the axis L. And the two magnets 221 are driven by a centrifugal force generated by the rotation of the rotating member 21, and move relative to the rotating member 21 from the first position in a direction away from the axis L toward a second position (as shown in FIG. 6). The spring 2231 of each position adjusting unit 223 is stored with a restoring force to respectively urge the two magnets 221 to return to the first position. The second position where the respective magnets 221 are located refers to a position away from the bottom of the groove of the receiving groove 2121 but not protruding from the edge of the rotating member 21 (ie, the notch of the receiving groove 2121). Moreover, when the magnet 221 of the present embodiment moves, the tubular portion 2233a of the movable frame 2233 is guided through the tubular portion 2232a of the fixed frame 2232, so that the magnet 221 in the tubular portion 2233a of the movable frame 2233 can be opposed to the receiving groove. 2121 is a linear motion.

Therefore, when the rotating member 21 continues to rotate, the two magnets 221 and the movable frame 2233 are both maintained in the second position, that is, both the magnets 221 and the inner edge of the flow tube 111 of the housing 11 are maintained at The two magnetic poles 2211 of the first magnetic module 22 face the two core portions 1211 of one of the first magnetic conductive units 121 in the radial direction, respectively, when the rotor assembly 2 is rotated to a predetermined position. As shown in FIG. 6, at a predetermined position, the center line C of the two core portions 1211 passes through the two magnets 2213) and abuts against the soft magnetic conductive brush 122, thereby making the two magnets The magnetic force generated by the magnetic pole end 2211 is transmitted to the two core portions 1211 via the soft magnetic conductive brush 122, so that the coil 1212 wound on the two core portions 1211 generates an induced current to generate electricity. effect.

Further, when the rotor assembly 2 is rotated to a predetermined position with the axis L as the axis, the two magnetic poles 2211 of the first magnetic module 22 face the two cores of one of the first magnetic conductive units 121 in the radial direction. The portions 1211 are respectively abutted with the free ends of the two soft magnetic conductive brushes 122 on the two core portions 1211, so that the magnetic energy generated by the two magnets 221 from the magnetic pole ends 2211 passes along the first magnetic module 22 (ie, two The magnet 221 and the magnetic conductor 222), the soft magnetic conductive brush 122, and the first magnetic conductive unit 121 (ie, the two core portions 1211 and the conduction member 1213) constitute a magnetic loop F. Further, since the first magnetic conductive module 12 has a plurality of first magnetic conductive units 121, when the rotor assembly 2 is rotated about the axis L, the first magnetic module 22 can be sequentially Facing the first magnetic conductive units 121, the magnetic force generated by the two magnetic pole ends 2211 constitutes the magnetic force loop F along the first magnetic module 22 and the first magnetic conductive unit 12 facing thereto.

Thereby, the magnet 221 transmits the magnetic force to the core portion 1211 of the first magnetic conductive unit 121 via the soft magnetic conductive brush 122, so that the magnetic force between the magnetic pole end 2211 of the magnet 221 and the corresponding core portion 1211 is transmitted as The zero gap is used to enhance the magnetic transmission effect, and the magnet 221 or the spiral blade 212 can be prevented from colliding with the core 1211 due to improper design of the gap. Furthermore, the power generating device 100 can achieve the effect of increasing the amount of power generated by the magnetic coil F formed by the first magnetic module 22 and the first magnetic guiding unit 121 when the rotor assembly 2 is rotated relative to the stator assembly 1. And the number of the first magnetic guiding units 121 can be increased as needed to further increase the amount of power generation.

If the fluid outside the power generating device 100 (eg, wind) no longer enters the flow passage 113 of the housing 11, the rotating member 21 will gradually slow down its rotational speed until it is stationary, at which time the centrifugal force is less than the restoring force, and The spring 2231 will gradually release its restoring force in synchronization to push against the side wing portion 2232b of the fixed frame 2232 and the movable frame. The side flap portion 2233b of 2233, in turn, urges the magnet 221 fixed to the movable frame 2233 to move from the second position to the first position.

Furthermore, as shown in FIG. 2 to FIG. 4, the stator assembly 1 of the present embodiment can also be provided with a second magnetic module 13 in the housing 11, and the second magnetic module 13 includes a plurality of second magnetically conductive The unit 131, and the rotor assembly 2 of the present embodiment can be provided with a second magnetic module 23 on the spiral blade 212 of the rotating member 21. The configuration and arrangement principle of the second magnetic module 13 and the second magnetic module 23 are similar to the first magnetic module 12 and the first magnetic module 22, and thus are no longer directed to the second guide. The magnetic module 13 and the second magnetic module 23 will be described in detail.

In addition, the position, the number, and the shape of the spring 2231 in the position adjusting unit 223 can also be adjusted according to the needs of the designer. For example, as shown in FIG. 7 and FIG. 8, the first magnetic module 22 only includes a position adjusting unit 223, and the two magnets 221, the magnetic conductor 222, and the position adjusting unit 223 of the first magnetic module 22 are all disposed in the same receiving groove 2121, and the two magnets 221 are respectively abutted. At opposite ends of the magnetic conductor 222. In addition, the spring 2231 may be a substantially C-shaped or U-shaped sheet-like configuration (not shown), similar to a leaf spring. The central portion of the sheet-like spring 2231 is fixed to the groove bottom of the accommodating groove 2121, and the two ends of the sheet-shaped spring 2231 correspond to the two magnets 221 to provide a restoring force corresponding to the magnet 221 and the magnetic conductor 222. .

The conductive member 1213 is disposed on the housing 11 and includes two circular guides. The magnetic ring 1213a and at least one magnetic conductive connection portion 1213b connected between the two magnetic conductive rings 1213a.

In more detail, the two core portions 1211 of each of the first magnetic conductive units 121 are respectively located inside the two magnetic conductive rings 1213a, and the two core portions 1211 of each of the first magnetic conductive units 121 and the two guiding portions respectively The magnetic rings 1213a are connected, and the magnets 221 on the first magnetic module 22 are respectively located within the space surrounded by the two magnetic rings 1213a, so that the magnetic force generated by the magnet 221 can pass through each first guide. One of the core portions 1211 of the magnetic unit 121 is sequentially transferred to the other core portion 1211 via one of the magnetic conductive rings 1213a, the adjacent magnetic conductive connecting portion 1213b, and the other magnetic conductive ring 1213a thereof. That is, the magnetic force can form a magnetic loop F along the first magnetic module 22, the two core portions 1211 of each of the first magnetic conductive units 121, and the conductive members 1213.

Moreover, the outer surface of the conductive member 1213 does not protrude from the outer surface of the housing 11, and the outer surface of the conductive member 1213 is substantially aligned with the outer surface of the housing 11 in this embodiment, but Limited.
