Abstract

A hinge mechanism is applicable to an electronic device. Two components of the electronic device pivotally open and close relative to each other via the hinge mechanism. The hinge mechanism includes a fixed frame, a pivot, a support frame, and an arc-shaped rack. The pivot is pivotally mounted on the fixed frame and has an external gear. The support frame is slidably coupled to the fixed frame and has an arc-shaped groove. The arc-shaped rack is disposed in the arc-shaped groove and movably meshes with the external gear. The support frame slides relative to the fixed frame and drives the pivot to rotate via the arc-shaped rack and the external gear, causing the support frame to pivot relative to the fixed frame along a virtual axis.
