AI Technical Summary
Existing mouse wheels have issues with tactile feedback when scrolling quickly, which affects efficiency and makes operation cumbersome. Switching between damping states is also cumbersome.
An adaptive roller device is adopted, which automatically switches the damping state through the cooperation of planetary gear assembly and magnet and bearing. It uses the magnetic force and inertial force of magnet and bearing to switch between tactile and high-speed rotation at different stages of rotation, combined with the feedback electrical signal of Hall sensor.
It enables a smooth switching between slow and fast rotation of the scroll wheel, providing stability and ease of operation, and enhancing the user experience.
