Abstract:
1. A flickering device for an automobile wheel, the flickering device flickering using electromotive force, generated by interaction between a magnetic force and a coil unit as a rotating body rotates, as an electric power source, the flickering device comprising: a housing, a coupling ring inserted from an inside of an wheel hub to an outside thereof to couple the housing to a wheel, a deviation correction ring engaged with the coupling ring before the coupling ring combining with the housing to compensate for a gap which may occur between the housing and the coupling ring when the housing and the coupling ring are combined with each other through the wheel hub in a screw manner the wheel hub having a thickness thinner than a standard thickness, a stopper protrusion of the coupling ring for stopping the deviation correction ring, a fastening hole formed through a portion of the coupling ring to prevent the housing and the coupling ring from being loosened from each other by external force having vibrations, during the operation of the automobile after the housing and the coupling ring are combined with each other in a screw manner, and a fastening pin tightened into the fastening hole; a fastening shaft formed at a center of an inside of the housing, a magnetic core and a washer fitted on the fastening shaft, a frame seated in the housing, a power generation unit inserted into a lower end of the frame, a notch formed on one side of a lower end of the frame, and a power supply terminal of the power supply unit fitted into the notch; a weight partially inserted into the frame, a bearing inserted into a cylindrical depression formed at a center of an upper end of the frame, a bearing fastening protrusion formed on the fastening shaft of the housing passing through the bearing inserted into the cylindrical depression, and a bolt tightened into a fastening hole of the fastening shaft to combine the bearing, the frame and the housing with each other; a circular circuit board seated on the frame, LEDs and elements mounted on the circuit board, a fastening protrusion formed on the frame to fasten the circuit board to the frame, and a fastening notch formed on the circuit board to be engaged with the fastening protrusion; a cap seated on the circuit board, insertion recesses formed in the circumference of the cap to correspond to the LEDs mounted along the circumference of the circular circuit board, a fastening recess formed in the cap to fasten the cap to the frame and the circuit board, and a film coated on a surface of a top of the cap; and a transparent casing fitted into the housing, a cover combined with the housing to protect the transparent casing, a cut-away portion formed in the cover to allow light emitted from the LEDs to pass therethrough, a fastening pin adapted to fasten the cover and the housing, and a fastening hole of the cover adapted to accommodate the fastening pin.
