AI Technical Summary
Technical Problem
Existing keyboard mechanisms, whether using rubber domes or springs, often fail to effectively provide appropriate rebound force and switch triggering due to improper stress deformation characteristics, leading to ineffective switch triggering and suboptimal pressing feel.
Method used
An elastic protrusion with a bottom ring portion, top ring portion, outer oblique ring wall, and inner oblique ring wall is designed to enhance rebound force and stability, featuring a narrowed upper portion and varying thicknesses to ensure uniform deformation and reliable switch triggering.
Benefits of technology
The elastic protrusion provides improved rebound force, enhanced pressing feel, and reliable switch triggering, ensuring consistent and effective operation.

Abstract
An elastic dome is used in a keyswitch structure and includes a bottom ring portion, a top ring portion, an outer oblique annular wall, a trigger post, and an inner oblique annular wall. The top ring portion is located above the bottom ring portion in a vertical direction. The outer oblique annular wall obliquely connects the top ring portion and the bottom ring portion between the top ring portion and the bottom ring portion. The trigger post is located inside the outer oblique annular wall. The inner oblique annular wall extends obliquely downward from the inside of the top ring portion and is connected to the trigger post. In an embodiment, the bottom ring portion has a narrowed upper portion and a lower portion connected to the upper portion. In another embodiment, when the elastic protrusion is compressed to a depressed state, the connection between the upper portion and the lower portion is higher than the connection between of the top ring portion and a top conical surface of the inner oblique annular wall. In another embodiment, the inner oblique annular wall is thinner in thickness from the top ring portion to the trigger post.
