Mouse scroll wheel mechanism

Abstract

A mouse scroll wheel mechanism includes: a carrying unit, a roller, a plurality of sheet-shaped magnetic conductive members and a magnet member; the carrying unit is provided with a first mounting member and at least a second mounting member, and the roller is rotatably disposed on the first mounting member; the plurality of sheet-shaped magnetic conductive members have the same shape and are distributed at equal angles and equal intervals around the circumference of the roller, and two adjacent sheet-shaped magnetic conductive members are separated by an non-magnetic conductive object; the magnet member has a magnetic pole side with strong magnetism, and the magnet member is disposed on the second mounting member with the magnetic pole side facing the roller at a distance. When the roller rotates, the intermittent magnetic restoring force generated between the magnet member and the sheet-shaped magnetic conductive member allows users to feel the resistance.
