AI Technical Summary

Technical Problem

Existing L-shaped button devices suffer from problems such as time-consuming assembly, high cost, and noise generation when pressed due to the use of a balance bar.

Method used

The design employs a substrate, thin-film circuit board, elastomer, keycaps, and scissor-switch module. The scissor-switch module includes a first bracket, a second bracket, and a third bracket. Through the structural design of these brackets, the use of a balance bar is avoided, achieving stable support for the keycaps and simplifying assembly.

Benefits of technology

It achieves stable support for the keycaps, saves time and costs during assembly, and is less prone to noise when pressed, thus reducing the failure rate.

Abstract

An L-shaped key device includes a substrate, a thin-film circuit board disposed on the substrate, an elastomer disposed on the thin-film circuit board, a keycap shaped like an inverted L at the top of the elastomer, and a scissor-switch module located between the substrate and the keycap. The scissor-switch module includes a first support, a second support, and a third support. The first support is pivotally connected to the substrate and the keycap, and has a front receiving hole and a rear receiving hole. The second support is located within the front receiving hole and is rotatable about a first axis; the second support is inverted T-shaped and has a left top block pivotally connected to the keycap and a right bottom block pivotally connected to the substrate. The third support is located within the rear receiving hole and is rotatable about a second axis; the third support is pivotally connected to the substrate and the keycap. The structure of the scissor-switch module provides good support for the keycap, saving assembly time and reducing assembly costs.
