Abstract

A hub generator for bicycle that can be correctly grounded and supply electricity. A hub generator for bicycle includes a hub casing rotating along with the front wheel (4) and affixed with a magnet around an axle surrounded by a generating coil (21), where the rotation of the front wheel (4) would generate electricity. This invention is characterized in that: the power supply line (23) for supplying electricity generated by the generating coil and the grounding of the generating coil (21) serve as a power supply socket (18) provided outside of the hub casing (18). To supply electricity to the electrical components of the bicycle, the power supplying wire (26) and the grounding wire (26) are connected to the power supply socket (18) so as to supply electricity to the electrical components without damaging the bicycle frame while ensuring conduction of electricity.

Description

technical field

[0001] The present invention relates to a bicycle hub dynamo provided on a front wheel of a bicycle or the like. Background technique

[0002] As a conventional hub dynamo for bicycles, the following structure is known: the hub shell of the front wheel whose inner surface is fixed with magnets alternately having N poles and S poles is rotatably supported on the axle protruding from the hub shell at both ends. The generator coil is installed on the axle in the hub shell, and at the same time, the output terminal powered by the generator coil is fixed on the axle outside the hub shell. This type of generator is installed on the bicycle by inserting both ends of the axle shaft with a circular cross section protruding from the hub shell into the U-shaped mounting groove of the bicycle front fork, and screwing nuts into the threaded part of the axle shaft. And when it is installed on the front fork, a toothed washer is inserted between the nut and the front fork,...
