Mouse device
A mouse device comprising a base, a first circuit board, a scroll wheel bearing, a light-emitting component and a scroll wheel. The first circuit board is disposed on the base. The scroll wheel bearing is mounted to the base. The light-emitting component is disposed on the scroll wheel bearing, and is electrically connected to the first circuit board. The scroll wheel is rotatably connected to the base and the scroll wheel bearing. The light-emitting component is disposed between the scroll wheel and the scroll wheel bearing. By disposing the light-emitting component in the scroll wheel, the light emitted from the light-emitting component would pass through the scroll wheel and the scroll wheel bearing to the outside, which can be evenly emitted from each side of the scroll wheel and the scroll wheel bearing for even light distribution and scrolling without obstruction.
1. A mouse device, comprising:
a base;
a first circuit board disposed on the base;
a scroll wheel bearing, wherein the scroll wheel bearing comprises a bearing body and a protrusion connected to the bearing body, and the scroll wheel bearing is mounted to the base through the protrusion;
a scroll wheel mounted to the base and rotatably connected to the scroll wheel bearing, wherein the scroll wheel comprises a scroll wheel body, the scroll wheel body comprises an opening, the bearing body is disposed in the scroll wheel through the opening such that an accommodating space is entirely enclosed by the scroll wheel and the bearing body of the scroll wheel bearing; and
a light-emitting component disposed in the accommodating space, and the light-emitting component being electrically connected to the first circuit board.
2. The mouse device according to claim 1 , wherein the light-emitting component comprises a second circuit board and a light-emitting element; the second circuit board is disposed on the scroll wheel bearing; and the second circuit board is electrically connected to the first circuit board; the light-emitting element is disposed on and electrically connected to the second circuit board.
3. The mouse device according to claim 2 , wherein the first circuit board comprises a first electrical connector; the second circuit board comprises a second electrical connector; the second electrical connector is electrically connected to the first electrical connector; the light-emitting element and the second electrical connector are respectively disposed on the same or different surfaces of the second circuit board.
4. The mouse device according to claim 2 , wherein the number of light-emitting element is plural; the plurality of light-emitting elements are respectively disposed on a surface of the second circuit board away from the scroll wheel and a surface of the second circuit board close to the scroll wheel.
5.
