Key structure

Abstract

The invention discloses a key structure. The key structure comprises a key cap, a bottom plate, a first bracket and a second bracket; the first bracket and the second bracket are pivotally connected with each other and connected between the key cap and the bottom plate; the first bracket includes a shaft groove, a shaft portion and a protruding interference portion which are arranged adjacently; the second bracket correspondingly includes a shaft portion, a shaft groove and a groove interference portion which are arranged adjacently; the groove interference portion has an avoidance space and is provided with a stopping block disposed beside the avoidance space; the shaft grooves and shaft portions of the first bracket and the second bracket are embedded into each other, so that the first bracket and the second bracket can be pivotally connected to each other; the protruding interference portion is located in the avoidance space; and the stopping block prevents the protruding interference portion from escaping from the avoidance space. According to the key structure of the invention, the axial deformation of the two brackets can be suppressed, and the stability of connection betweenthe two brackets can be improved.

Description

technical field [0001] The present invention relates to a key structure, in particular to a key structure with mutually pivoted brackets. Background technique [0002] A general keyboard mainly includes a base plate and a plurality of keycaps disposed above the base plate. In principle, each keycap is connected to the base plate via a lifting mechanism so as to be able to move up and down relative to the base plate. A common lifting mechanism, such as a scissor leg bracket, is composed of two mutually pivoted brackets, such as an inner ring bracket and an outer ring bracket. For example, the inner ring bracket protrudes a rotating shaft axially outward on both sides of the inner ring bracket, and a shaft hole is formed on the corresponding inner side of the outer ring bracket, and the pivot connection of the two brackets is realized by inserting the shaft into the corresponding shaft hole. . In actual operation, at least one of the two brackets needs to be deformed in the ...

AI Technical Summary

Problems solved by technology

However, in this interfitting structure, the hole is in the form of a perforated hole so that the corresponding hole and the shaft can be smoothly connected. This structural feature also makes the two brackets easy to separate after the pivot connection, affecting This affects the stability of the connection between the two brackets, and also affects the stability of their movement.

If the degree of interference between the corresponding holes and shafts during assembly is increased in order to improve the joint stability between the two brackets, it will easily cause assembly difficulties and residual deformation of the pivotal structure of the two brackets, which will also affect the The operating stability of the two brackets
