The best mode for implementing the present invention will be described below with reference to the drawings.

1 to 3, a wheel automatic power generating device according to the present invention is provided with a rotating part composed of a coil 4 capable of generating electric power, a magnetic pole group and a first cover 2, a second cover 6, and a first cover A spacer ball bearing device composed of a ball spacer 3, a ball 31, and a ball correction ring 1 between 2 and the second cover 6. The magnetic pole group is formed by a first magnetic pole 41 and a second magnetic pole 42. The two magnetic poles 41 and 42 protrude downward and upward on the inner edge of a circular ring body, respectively. And 421, the coil 4 is wound on a plastic skeleton 40 with a hollow I-shaped cross-section, and two ends of the coil 4 form an electric power output line 401 for connecting a light-emitting component 7 described later. The coil 4 (including the bobbin 40) is disposed between the first magnetic pole 41 and the second magnetic pole 42 so that the axial inner ring neck formed by the pole pieces 411 and 421 is adhered to the inner edge surface of the coil 4, and The radial toroids of the first magnetic pole 41 and the second magnetic pole 42 sandwich the coil 4 therein.

Referring again to FIG. 1 and FIG. 2, the coil and the magnetic pole group are installed in a space enclosed by the first cover 2, the ball spacer 3, the second cover 6, and the ball correction ring 1. A center pillar 60 having a central hole 601 that can be incorporated into the wheel shaft is perpendicularly extended at the closed inner bottom side center of the second cover body 6, and the inner edge wall of the second cover body 6 is near the middle section and near the upper opening edge, respectively. A circle of the second groove 61 and the internal thread 62 are formed at each place; a ring magnet 5 is sleeved around the center pillar 60, and the above-mentioned coil and magnetic pole group are sleeved around the ring magnet 5.

A circle of the first recessed groove 21 opposite to the aforementioned second recessed groove 61 is formed on the outer edge wall surface of the first cover body 2. The closed top surface thereof is provided with a shaft hole 20 at the center and PT / CN01 / 01482 A Y-shaped fixing frame 22 and a Y-shaped movable frame 23 screwed to the top surface by a fixing piece 231 are formed at two opposite positions; two other opposite positions of the shaft hole 20 are formed respectively The two convex connecting sleeves 63 which communicate with each other inside and outside, and both of the Y-shaped fixing frame 22 and the movable frame 23 can be used for the wheel spokes 91 to be interposed therebetween to drive the first cover 2 to rotate (as shown in FIG. 5). The first cover body 2 having an outer diameter smaller than the inner diameter of the second cover body 6 is sleeved inside the second cover body 6, and the first and second grooves 21 and 61 are relatively formed into a circle as shown in FIG. 3. The shape is so as to fit and install the ball 31.

The ball spacer 3 is ring-shaped and is provided with a plurality of ball holes 30 at an equal distance. Ball balls 31 are respectively installed in the ball holes, and the ball 31 is positioned at the first and the second through the ball holes 30. Two grooves 21 and 61. The ball spacer 3 on which the balls 31 have been mounted is installed between the first and second recesses 21 and 61 facing each other of the first cover 2 and the second cover 6 (see FIGS. 3 and 4). ), It is not necessary to fill the entire circumference between the first and second grooves 21 and 61, and only a few balls are required (in this embodiment, six balls are evenly distributed, and the ball spacer 3 is used to prevent them from being random. Displacement) can achieve the purpose of the first and second covers 2, 6 smoothly relative rotation.

However, even after assembling as described above, a space is formed above the inner edge side of the second cover 6 so that the balls 31 may be displaced. Therefore, the ball correction ring 1 is screwed into the gap. The external thread 10 provided thereon is screwed to the internal thread 62 of the second cover 6 as shown in FIG. 3. There is a gap between the ring magnet 5 and each of the pole pieces 411 and 421.

Referring to FIGS. 5 and 6, the wheel axle 90 of the wheel is axially extended into the shaft hole 20 of the first cover body 2 and the center hole 601 of the second cover body 6, and an outer end of the wheel shaft 90 is fixed to the frame 9 and simultaneously The axle 90 can be fixed on the second cover 6, and the wheel spokes 91 are first mounted on the fixed frame 22, and the movable frame 23 is adjusted so that they are also mounted on the wheel spokes 91 and then locked. The rotating part is driven to rotate by the rotation of the wheel. The rotating part and the second cover 6 and the ring magnet 5 fixed to the axle 90 generate a relative circular motion through the ball 31. The relative circular motion makes the magnetic field of the ring magnet 5 at the first, A periodically changing alternating magnetic field is generated on the second magnetic poles 41 and 42, and an induced electromotive force is generated on the coil 4 to drive the light emitting component 7.

As shown in FIG. 1, a lamp body suitable for an automatic wheel generating device of the present invention is composed of a light emitting component. T CN01 / 01482

7. The light guide rod 8 and the transparent sleeve 80 are formed. The light-emitting component 7 may be in the form of a light emitting diode (LED) and the like. The quilt is placed inside the light guide rod 8. The light guide rod 8 is set on the top of the first cover 2. On the connection sleeve 63 on the surface, the positive and negative leads of the light-emitting component 7 are connected to the power output line 401 of the coil 4 through the connection sleeve 63, and a transparent sleeve 80 is placed on the light guide rod 8 for waterproof and dustproof . 7 may be a light-emitting element may be a single color or in a plurality of different colors, and the peripheral surface of the light guide rod 8 is formed with a plurality of concave-convex shape portion ⁸² by reflection and refraction different media interface concave loop of the single light source generates The multi-point effect and different color light emitting components can produce multiple combinations with different numbers of light spots. In addition, the light at the four-ring 82 is brighter than a general straight rod light guide without the concave ring 82. Since the light guide rod 8 with the transparent sleeve 80 is located at the radial position between the wheel shaft and the wheel frame, when the wheel rotates, the entire wheel surface can have a bright dazzling aura, thereby providing a warning and improving the safety effect. It is also possible to install a flashing circuit for the light-emitting component 7, which can have a more obvious warning safety effect.

Referring to FIGS. 7, 8 and 9, the concave-convex shape portion formed on the outer surface of the light guide rod 8 may form a chamfered groove ring ^{82 a} shown in FIG. 7, a convex ring ⁸² b shown in FIG. 8, or FIG. 9. The rough torus 82c and the like shown all have the same effect and function. Industrial applicability

Since the wheel automatic power generation device according to the present invention has a spacer ball bearing device, it does not have the disadvantage of inconvenient assembly due to the use of another bearing during assembly; because of the spacer ball according to the present invention, The ball of the bearing device is located between the first groove of the first cover and the second groove of the second cover, and is located in the ball hole of the ball spacer, so only a few balls can be used to reach and fill The rotation effect of the same circumferential length of the two grooves of the ball, the reduction of the number of balls will correspondingly reduce their own weight, and the crust will also be simplified. In addition, the device itself will become smaller and more suitable for the wheel axle; The spacer-type ball bearing device according to the present invention has a ball correction ring, so that it is possible to effectively prevent the ball from being displaced or dislodged due to factors such as wheel bumps.
