Electronic device
View Patent ↗An electronic device including a base and an inclination-adjusting element is provided. The base has a receiving recess. The inclination-adjusting element is disposed within the receiving recess. The inclination-adjusting element includes a shaft and an eccentric wheel. The eccentric wheel is configured to rotate around the shaft to raise or lower the base.
1. An electronic device comprising:
a base having a receiving recess, a side wall of the receiving recess having a guide rail and a plurality of second engaging portions, the guide rail having a first engaging portion; and
an inclination-adjusting element disposed within the receiving recess and comprising:
a shaft; and
an eccentric wheel configured to rotate around the shaft to raise or lower the base,
and comprising a first bump and a second bump, the first bump adjacent to the shaft and disposed in the guide rail;
wherein when the base is raised to a highest position, the second bump is detached from all of the second engaging portions and located at a position lower than the base, and the first bump is engaged with the first engaging portion to fix the shaft.
2. The electronic device according to claim 1 , wherein when the eccentric wheel rotates, the first bump is selectively engaged with or detached from the first engaging portion.
3. The electronic device according to claim 2 , wherein the guide rail has a plurality of first engaging portions, and when the eccentric wheel rotates, the first bump is selectively engaged with or detached from one of the first engaging portions.
4. The electronic device according to claim 1 , wherein while the base is raised to the highest position from a lowest position, the second bump is selectively engaged with or detached from one of the second engaging portions.
5. The electronic device according to claim 1 , wherein the eccentric wheel further comprises a flexible cantilever extending towards a circumference of the eccentric wheel from a center of the eccentric wheel, and the second bump is disposed at one end of the flexible cantilever.
6. The electronic device according to claim 1 , wherein a central angle between the second bump and the first bump is 90 degrees.
7. The electronic device according to claim 1 , wherein the inclination-adjusting element further comprises a sheath disposed on a circumference of the eccentric wheel, and a plurality of engraving marks is disposed on a surface of the sheath.
8. The electronic device according to claim 7 , wherein the sheath is formed of a soft rubber.
9. The electronic device according to claim 1 , wherein the receiving recess and the inclination-adjusting element are disposed on a first side of the base, and the inclination-adjusting element is configured so that the first side is raised gradually while the eccentric wheel rotates.
10. The electronic device according to claim 1 , further comprising at least two sets of the receiving recess and the inclination-adjusting element, wherein the two sets are respectively disposed on a first side and a second side opposite to the first side of the base.
11. The electronic device according to claim 1 , wherein the electronic device is a keyboard, a mouse, a projector, a touch pad, a drawing board or a display stand.
