Abstract:
A self-generating light-producing skateboard, comprising:a deck; front and rear wheel sup porter assemblies mounted to predetermined positions at an underside of said deck, each of said wheel supporter assemblies including a wheel supporter, at least one of which is fixedly provided on at least one end with a coil chamber; at least one induction coil assembly located in said coil chamber with an axle in said wheel supported extended therethrough, each said at least one induction coil assembly including a coil support, left and right outer magnetic pole halves, a copper foil, an insulating washer, and an inner magnetic pole, said axle extending through said inner magnetic pole, said copper foil, and said washer, said coil support extending at least partially around said inner magnetic pole, and said outer magnetic pole halves together extending at least partially around said coil support; a coil being wound around said coil support with two lead-out wires connected to wires that are then connected to at least one light-emitting element fixedly connected to an outer periphery of said deck; four wheel assemblies separately mounted to two ends of said two wheel supporters of said front and said rear wheel supporter assemblies, each said wheel assembly including a wheel rotatably mounted to an outer en of said axle; at least one of said wheels that is mounted to an outer side of said at least one coil chamber being provided at an inner end surface along an axle hole with a plurality of holes for each receiving a magnet therein; and a light-transferring strip mounted around an outer periphery of said deck; whereby when said wheel rotate at high speed, said magnets set at the inner end surface of said at least one wheel interact with said at least one induction coil assembly to generate current that drives said at least one light-emitting element to emit light, and said light in transferred via said light-transferring strip to light the outer periphery of said deck, enabling said skateboard to produce light without batteries and be safer for use.
