AI Technical Summary

Technical Problem

Existing trackball mice suffer from hand muscle fatigue during use and cannot dynamically adjust posture based on muscle fatigue levels, leading to accumulated upper limb fatigue.

Method used

A trackball mouse was designed. By setting an anti-slip layer and damper on the bottom of the mouse body, combined with a limiting mechanism and a connecting mechanism, the mouse body can adjust its angle without changing its position when rotating. The connection methods include magnetic adsorption components, adhesive layers, screw fastening components and snap-fit ​​structures, as well as the limiting design of limiting columns and limiting grooves.

Benefits of technology

It achieves the ability to adjust the angle as needed while maintaining mouse stability, thereby relieving hand muscle fatigue and reducing the accumulation of upper limb fatigue.

Abstract

The application relates to the technical field of trackball mice, and discloses a trackball mouse which comprises a mouse body, a fixed groove arranged at the bottom of the mouse body, a base, an avoiding recess arranged at the outer periphery of the base and corresponding to a release hole of the mouse body, an anti-skid layer arranged at the side of the base away from the mouse body, and a damper which comprises a mounting block and a damping ring and is limited by a limiting mechanism. The anti-skid layer improves the anti-skid capacity of the mouse body, and the damper and other structures are arranged in a matched mode, so that the mouse body can rotate with resistance when the mouse body is subjected to a torsion force, and the angle of the mouse body can be adjusted without displacement of the position of the mouse body.
