摘要
A keyboard lift mechanism includes a sliding block, a link bar, a hinge assembly, a driving member and a resilient member. The sliding block is slidably disposed inside a lower casing. Both ends of the link bar are pivoted to a keyboard and the sliding block, respectively. The driving member is coupled to the hinge assembly. The resilient member abuts against the lower casing and the sliding block. The resilient member and the driving member drive the sliding block to move in a first direction when the upper casing rotates in a first rotating direction, such that the link bar is driven to rotate the keyboard to a containing position, and drive the sliding block to move in a second direction when the upper casing rotates in a second rotating direction, such that the link bar is driven to rotate the keyboard to an opening position.
