Dual spin speed for mouse scroll wheel
A mouse configured to communicatively couple to an information handling system may include an enclosure, a scroll wheel enclosed within the enclosure, with a portion of the scroll wheel extending from the enclosure, the scroll wheel configured to rotate about a first rotational axis, a scroll wheel gear mechanically coupled to the scroll wheel and configured to rotate about the first rotational axis at the same angular velocity as the scroll wheel, and a damping gear assembly. The damping gear assembly may include a damping gear enclosed with the enclosure and configured to rotate about a second rotational axis parallel to the first rotational axis of the scroll wheel and a slider enclosed within the enclosure and exposed through an opening of the enclosure proximate to the portion of the scroll wheel which is exposed through the enclosure, the slider mechanically coupled to the damping gear to enable a user to selectively engage the damping gear to the scroll wheel gear and selectively disengage the damping gear from the scroll wheel gear by interacting with the slider, such that the damping gear inhibits rotation of the scroll wheel when the damping gear is engaged with the scroll wheel gear and such that the scroll wheel rotates freely when the damping gear is disengaged from the scroll wheel gear.
1. A mouse configured to communicatively couple to an information handling system, comprising:
an enclosure;
a scroll wheel enclosed within the enclosure, with a portion of the scroll wheel extending from the enclosure, the scroll wheel configured to rotate about a first rotational axis;
a scroll wheel gear mechanically coupled to the scroll wheel and configured to rotate about the first rotational axis at the same angular velocity as the scroll wheel; and
a damping gear assembly comprising:
a damping gear enclosed with the enclosure and configured to rotate about a second rotational axis parallel to the first rotational axis of the scroll wheel; and
a slider enclosed within the enclosure and exposed through an opening of the enclosure proximate to the portion of the scroll wheel which is exposed through the enclosure, the slider mechanically coupled to the damping gear to enable a user to selectively engage the damping gear to the scroll wheel gear and selectively disengage the damping gear from the scroll wheel gear by interacting with the slider, such that the damping gear inhibits rotation of the scroll wheel when the damping gear is engaged with the scroll wheel gear and such that the scroll wheel rotates freely when the damping gear is disengaged from the scroll wheel gear.
2. The mouse of claim 1 , wherein the damping assembly further comprises:
a gear box mechanically coupled to the damping gear; and
a link bar mechanically coupled between the gear box and the slider.
3. The mouse of claim 2 , wherein the damping assembly is constrained to move in a linear direction between a first position in which the damping gear is engaged with the scroll wheel gear and a second position in which the damping gear is disengaged from the scroll wheel gear.
4. The mouse of claim 1 , wherein the damping gear is mechanically coupled to a mechanical encoder configured to inhibit rotation of the scroll wheel when the damping gear is engaged with the scroll wheel gear.
5. The mouse of claim 3 , wherein the mechanical encoder is configured to provide tactile feedback to the scroll wheel via the damping gear and the scroll wheel gear.
6. The mouse of claim 1 , further comprising:
a magnet mechanically coupled to the scroll wheel and configured to rotate about the first rotational axis at the same angular velocity as the scroll wheel; and
a magnetometer located proximate to the magnet and configured to:
sense rotational motion of the magnet; and
generate an electrical or electronic signal based on a rotational motion.
7. The mouse of claim 6 , wherein the magnetometer comprises a Hall effect sensor.
8. A method comprising:
enclosing a scroll wheel within an enclosure of a mouse, with a portion of the scroll wheel extending from the enclosure and the scroll wheel configured to rotate about a first rotational axis;
mechanically coupling a scroll wheel gear to the scroll wheel and configured to rotate about the first rotational axis at the same angular velocity as the scroll wheel; and
enclosing a damping gear assembly within the enclosure, the damping gear assembly comprising:
a damping gear enclosed with the enclosure and configured to rotate about a second rotational axis parallel to the first rotational axis of the scroll wheel; and
a slider enclosed within the enclosure and exposed through an opening of the enclosure proximate to the portion of the scroll wheel which is exposed through the enclosure, the slider mechanically coupled to the damping gear to enable a user to selectively engage the damping gear to the scroll wheel gear and selectively disengage the damping gear from the scroll wheel gear by interacting with the slider, such that the damping gear inhibits rotation of the scroll wheel when the damping gear is engaged with the scroll wheel gear and such that the scroll wheel rotates freely when the damping gear is disengaged from the scroll wheel gear.
9. The method of claim 8 , wherein the damping assembly further comprises:
a gear box mechanically coupled to the damping gear; and
a link bar mechanically coupled between the gear box and the slider.
10. The method of claim 9 , further comprising constraining the damping assembly to move in a linear direction between a first position in which the damping gear is engaged with the scroll wheel gear and a second position in which the damping gear is disengaged from the scroll wheel gear.
11. The method of claim 8 , further comprising mechanically coupling the damping gear to a mechanical encoder configured to inhibit rotation of the scroll wheel when the damping gear is engaged with the scroll wheel gear.
12. The method of claim 11 , wherein the mechanical encoder is configured to provide tactile feedback to the scroll wheel via the damping gear and the scroll wheel gear.
13. The method of claim 8 , further comprising:
mechanically coupling a magnet to the scroll wheel and configured to rotate about the first rotational axis at the same angular velocity as the scroll wheel; and
locating a magnetometer proximate to the magnet and configured to:
sense rotational motion of the magnet; and
generate an electrical or electronic signal based on a rotational motion.
