Moving-magnet type mouse scroll wheel mechanism

Abstract

A moving-magnet type mouse scroll wheel mechanism includes: a carrying unit, a roller and a magnetic conductive member; the carrying unit is disposed with a first mounting member and at least a second mounting member; the roller is rotatably disposed on the first mounting member; a plurality of magnetic poles are distributed radially around the circumference of the roller, and the adjacent magnetic poles have opposite polarities to each other; the magnetic conductive member is disposed on the second mounting member, so that the magnetic conductive member faces the roller at a distance; when the roller rotates, intermittent magnetic restoring force can be generated between the magnetic pole and the magnetic conductor; when the roller is stopped without external force, the intersection of two adjacent magnetic poles of the roller is at the extension of the center line of the magnetic conductive member.
