Abstract
A light-generating bicycle pedal includes an axle, a pedal body mounted on the axle, and a light-generating unit including a magnet wheel, a coil device and a lamp unit. The pedal body is formed with a board receiving cavity to receive a circuit board of the lamp unit. The coil device includes a set of anchoring lugs to be anchored in a set of anchoring holes in the circuit board. Rotation of the axle relative to the pedal body results in rotation of the magnet wheel relative to the coil device, thereby inducing electrical currents in the coil device that are provided to the lamp unit via the anchoring lugs so as to enable the lamp unit to generate a light output.
Claims9
A light-generating bicycle pedal comprising:
- a pedal body formed with a tubular axle sleeve having an axle hole with front and rear ends, a cage member disposed around and connected to said axle sleeve, and a generator chamber disposed adjacent to one of said front and rear ends of said axle hole, said cage member including a pair of lateral cage portions that extend parallel to said axle sleeve and that are disposed respectively on opposite lateral sides of said axle sleeve, at least one of said lateral cage portions having an outer wall surface formed with a board receiving cavity;
- an axle extending into said axle hole and coupled rotatably to said axle sleeve;
- and
- a light-generating unit including a magnet wheel disposed in said generator chamber and mounted coaxially and co-rotatably on said axle, a coil device disposed in said generator chamber around said magnet wheel and mounted on said pedal body, and a lamp unit connected electrically to said coil device and mounted on said cage member;
- said coil device including a spool, a coil wound around said spool, and a pair of conductive caps capped on an assembly of said spool and said coil, each of said conductive caps being connected electrically to a respective end of said coil, said conductive caps being formed with a set of anchoring lugs;
- said lamp unit including a circuit board received in said board receiving cavity and having at least one lamp mounted thereon, said circuit board being formed with a set of anchoring. holes that permit extension of said set of anchoring lugs therein so as to establish electrical connection between said lamp unit and said coil device;
- wherein rotation of said axle relative to said pedal body results in rotation of said magnet wheel relative to said coil device, thereby inducing electrical currents in said coil device that are provided to said lamp unit via said anchoring lugs on said conductive caps so as to enable said lamp unit to generate a light output;
- wherein each of said anchoring lugs includes:
- a wider base section extending from one of said conductive caps, a restricted neck section extending from said base section and into one of said anchoring holes, and a head section extending from said neck section and twisted relative to said neck section to interconnect said circuit board and said coil device.
