Title: KEYS OF KEYBOARD AND ASSEMBLY METHOD THEREOF
Abstract:
The keys of a keyboard and an assembly method thereof. Each key of the keyboard includes a base (250), a sensor pad (240 )with a silicon rubber body (230), a scissor hinge (220) and a keycap, and also includes a middle plate (260) having a first surface (261) and a second surface (264), said middle plate (260) having a square hole (262) which penetrates the first surface (261) and the second surface (264), and said second surface (264) of the middle board (260) having grooves (263) formed along the four corners of the square hole (262). Stop-posts (222a, 224a) of the lower part of the scissor hinge (220) are set in the grooves (263) and the stop-posts (222b, 224b) of the upside part of the scissor hinge (220) pass through the first surface (261) of the middle plate (260) through the square hole (262) to connect to the keycap (210). The sensor pad (240) and the base (250) are fixed on the second surface (264) of the middle plate (260). The keys of the keyboard use the middle plate (260) to change the positioning structure of conventional scissor hinges, avoiding high-precision stamping of the base (250), and reducing processing difficulties and cost. The assembly method simplifies the whole assembly process and its manipulations.
