Input device and lifting structure for the input device

摘要

An input device has a base, two shafts, a touchpad and a switch. The shafts are pivotally connected between the base and the touchpad, and intersect each other. When the touchpad is pressed, the shafts rotate relative to the base and the touchpad simultaneously. As the shafts intersect each other, an intersection of the shafts is nearby or exactly on a center of the touchpad, such that the shafts can pull down the touchpad from the center. Thus, no matter what location on the touchpad is pressed, a pressing force is spread uniformly, which makes the touchpad move down evenly without tilting. Besides, pulling down the touchpad from the center can further prevent leverage and deformation of the touchpad, thereby avoiding affecting the user's feel of pressing. To sum up, the input device can make the touchpad move down evenly, and prevent the touchpad from deformation.

主权项

1. An input device comprising:
a base having multiple limits mounted on a top of the base; two shafts intersecting each other, and each shaft having two ends each respectively mounted in the corresponding limits of the base; a touchpad mounted on the shafts; and a switch mounted between the base and the touchpad; wherein the ends of each shaft each respectively protrude to two diagonally opposite corners of the touchpad, and each shaft is nonparallel to a corresponding side of the touchpad; wherein one of the shafts has a bending segment bent in the rod part, and the bending segment is curved to allow the other shaft to pass through the bending segment such that the shafts intersect each other; wherein the base has a bending recess formed in the top of the base to receive the bending segment of the shaft; wherein the touchpad has multiple pivot segments formed on a bottom of the touchpad and each shaft is rotatably mounted in the corresponding pivot segments of the touchpad; and wherein the base has multiple pivot recesses formed in the top of the base to respectively receive the pivot segments of the touchpad.
