Abstract

A panel embossing type thin film key hand feeling elastic sheet structure comprises a PCB base material, wherein four corner elastic sheets are arranged on key positions on the front surface of the PCB base material, a key panel is arranged on the upper layer of the front surface of the PCB base material, key convex hulls protruding outwards are arranged on the key panel, and the positions of the key convex hulls correspond to the positions of the four corner elastic sheets up and down; a hand feeling layer is arranged between the PCB substrate and the key panel, and hand feeling gaskets which vertically correspond to the positions of the key convex hulls and the four-corner elastic sheets are arranged on the hand feeling layer; according to the scheme, the hand-feeling elastic sheet structure of the panel embossed thin-film key shortens the stroke of the panel before the elastic sheet through the thickness of the hand-feeling gasket in the hand-feeling layer, improves the hand feeling of the key and increases the service life of the elastic sheet.

Description

Panel embossing type film key hand-feeling elastic sheet structure

Technical Field

The utility model belongs to the technical field of the film button, concretely relates to panel is pressed protruding type film button and is felt shell fragment structure.

Background

Traditional film class key structure, four corners shell fragment on key panel's the protruding package of button and the PCB board can have great space because middle glue film and protruding package special construction's reason between button protruding package and the four corners shell fragment, leads to the stroke before panel and the shell fragment to be increaseing, and the user feels not good when the button, and the button life-span shortens.

Therefore, the technical problem is solved by designing the touch elastic sheet structure of the embossed thin film key on the panel.
