Problems solved by technology

However, the design of the oblique guide groove is limited by the use of space in the horizontal direction of the notebook computer, and the oblique guide groove needs to be formed by machine tool processing, so the problem of excessive stroke tolerance caused by process variation is easy to occur

Abstract

A linkage mechanism includes a pivot assembly, a gear assembly, and a linkage assembly. The pivot assembly pivots around a first rotation axis. The gear assembly is pivoted with the pivot assembly andmoves in conjunction with the pivot assembly. The gear assembly includes a cam, and the cam pivots around a second rotation axis. The second rotation axis is not parallel to the first rotation axis.The linkage assembly is disposed at a side of the gear assembly and contacts the cam. When the pivot assembly drives the gear assembly to pivot, the linkage assembly abuts against the cam to produce arelative movement with the cam.

Description

technical field [0001] The present invention relates to a linkage mechanism, and in particular to a linkage mechanism suitable for electronic devices with different rotation axes. Background technique [0002] Generally speaking, a notebook computer is mostly composed of an upper body with a display screen and a lower body with a host system and / or a keyboard, wherein the upper body and the lower body are pivotally connected to each other through a hinge structure. However, the keyboard in the prior art is at the same height in both the use state and the non-use state, so that the overall thickness of the notebook computer cannot be reduced. Therefore, in order to reduce the overall thickness of the notebook computer to facilitate the convenience of carrying, the existing pivot design is to use the hinge cap (hinge cap) to rotate the sleeve with the inclined guide groove in an axially rotating manner, so that The linkage piece slidingly arranged in the guide groove of the s...
