AI Technical Summary
Technical Problem
The existing mouse scroll wheel has a complex structure and requires high processing and assembly techniques, which increases manufacturing costs and the possibility of structural failure.
Method used
By employing magnetic induction technology, a metal internal toothed ring and a permanent magnet unit are set in the concave cavity of the roller. The magnetic attraction between the permanent magnet and the internal tooth surface generates a scale feel, which simplifies the structural design and reduces the requirements for processing and assembly.
Benefits of technology
It simplifies the structural design, reduces manufacturing costs, effectively reduces the risk of production failures, and improves the mechanical feel and operating experience.

Abstract
The utility model discloses a mouse shuttle scroll wheel and mouse based on magnetic induction, which comprises a scroll wheel support, a scroll wheel rotatably arranged on the scroll wheel support, a concave cavity on one side of the scroll wheel in the axial direction, a metal inner gear ring arranged in the concave cavity, a fixed frame detachably connected to the scroll wheel support at one end and extending into the metal inner gear ring at the other end and provided with a permanent magnet mounting position, and a permanent magnet unit arranged in the permanent magnet mounting position and oppositely arranged with the inner tooth surface of the metal inner gear ring to be magnetically attracted to the inner tooth surface. In the present application, the fixed frame is stationary when the scroll wheel rotates, the metal inner gear ring is arranged in the concave cavity of the scroll wheel, and only the permanent magnet unit needs to be installed on the fixed frame, so that the permanent magnet unit is oppositely arranged with the inner tooth surface of the metal inner gear ring. When the scroll wheel rotates, the scale feeling is generated due to the magnetic attraction between the permanent magnet unit and the inner tooth surface of the metal inner gear ring, without the need to arrange side recessed teeth and outer protruding teeth on the fixed frame or to arrange side recessed teeth on the scroll wheel, thereby simplifying the structure.
