Abstract

The invention discloses a key lifting switching device, which comprises a keycap, a telescopic assembly, a switching mechanism and a pair of frames. The key cap is positioned above a bearing plate; the switching mechanism opens and closes a key signal corresponding to the lifting and descending motions of the keycap; the pair of frames is not contacted with each other and is oppositely arranged and provided with cavities; the corresponding bottom edges of the both frames can be arranged in first and second chute assemblies on both sides of the bearing plate in a sliding mode respectively, and the corresponding tops of the both frames are pivoted with first and second pivoting assemblies on both sides of a symmetry axis at the bottom of the keycap; synchronization sliding components for causing the pair of frames to synchronously lift and descend are arranged by passing through the cavities of the pair of frames; the bottom edges of the synchronization sliding components are pivoted in a third chute assembly on the bearing plate; the top edges of the synchronization sliding components are pivoted in a third pivoting assembly at the bottom of the keycap; and the bottom edges and the top edges of the synchronization sliding components are parallel to arm components of the two frames. The invention simplifies the structure of the key lifting switching device and improves the assembly clamp and the assembly process so as to further improve the production efficiency of the keyboard and the qualification rate of the finished product.

Description

【Technical field】 [0001] The invention relates to a keyboard and a key lifting switch device thereof, in particular to a keyboard used as an input device of an electronic instrument and a key lifting switch device of an ultrathin key used therein. 【Background technique】 [0002] In the CN101599379 patent announcement published on December 9, 2009, the applicant proposed a key lifting switch device and its assembly fixture and assembly process, abandoning decades of monopoly technology market relying on meshing or scissors "connecting" The key lifting switch device structure of the "rod part" is used instead of a pair of frames that are not in contact with each other and are formed with a cavity, combined with a synchronous slider that is used to suppress the synchronous lifting of the pair of frames to realize the guidance of the lifting action of the keycap. Citation, this technical improvement makes the key lifting switch device and its corresponding assembly process have ...
