Thin pressing type button structure

Abstract

A thin pressing type button structure comprises a sheet type conductor, wherein a plurality of protruding parts are provided on the lower surface of the sheet type conductor; a sheet type spacing layer set below the sheet type conductor, wherein the sheet type spacing layer comprises a plurality of holes that are correspond to the protruding parts of the sheet type conductor; and a conductive layer set below the sheet type spacing layer, wherein the surface of the conductive layer has conductive material. A preset value is set by setting a parameter to the sheet type spacing layer; a forcing value is generated by forcing the sheet type conductor; when the forcing value is less than the preset value, the sheet type conductor isn't electrically connected with the conductive layer; when the forcing value is larger than the preset value, the sheet type conductor is electrically connected with the conductive layer. The thin pressing type button structure in the invention can thin the buttons effectively.

Description

technical field [0001] The present invention relates to a thin pressure key structure, in particular, to a thin pressure key structure capable of sensing key force. Background technique [0002] Buttons have been widely used in input devices in the past. For example, consumer electronic products in daily life or large-scale processing equipment used in the industry need to be equipped with a button structure as an input device to operate the above-mentioned electronic products and processing equipment. . In response to the trend of thinner electronic products, there is a need for thinner buttons in design. [0003] In terms of structural design, the general key must have a supporting structure and elastic elements. The supporting structure allows the key to rise and fall vertically when pressed by the user, so as to trigger the switch. Most of the general keys are made of the outer frame of the keyboard or the scissors structure. Supporting structure; the elastic element e...

Problems solved by technology

However, because the supporting structure and elastic elements require a specific shape or structure to achieve their functions, the design of the key cannot achieve the purpose of thinning due to the shape or structure requirements.

[0004] In addition, in the structure of the known key, it is easy to produce the problem of uneven application of force, especially in the design of long keys, such as blank keys, when the user presses the edge of the key, the support structure may not be balanced due to uneven application of force. The ground rises and falls vertically, but the key signal cannot be triggered correctly
