Roller with self-contained generator device

Abstract

A roller is disposed rotatably on a roller shaft of a scooter, and has a housing which includes two housing halves that are interconnected to define an accommodation chamber therebetween. The housing halves define two shaft holes to permit extension of the roller shaft. A light-permeable rim element is sleeved fixedly on the housing. A light emitting unit is disposed within the rim element. An induction generator device is disposed within the accommodation chamber of the roller housing, and includes a mounting tube sleeved fixedly on the shaft, and a permanent magnet sleeved on the tube. A winding unit is disposed within the accommodating chamber, and includes a sheave and a coil unit that is wound on the sheave and that is in electrical connection with the light emitting unit. The sheave is sleeved rotatably on the magnet, and is fixed to the housing. Two ring-shaped conducting plates are mounted fixedly in the housing, and are in electrical and coaxial connection with the coil unit. Each of the conducting plates has an inner ring, an outer ring, and a plurality of elongated radially extending sheets which are angularly spaced apart from each other and which have radial inner ends integrally formed with the inner ring, and radial outer ends integrally formed with the outer ring.
