Description

Button structure and portable computer using the same

The invention relates to a button structure, and in particular to a button structure with a lightweight and thin design and a portable computer using the button structure.

The conventional button structure uses an elastic member to provide an elastic restoring force of the keycap, and supports the keycap with a scissor-foot structure, so that the keycap can be restored to the position before pressing. However, the structure of the scissor foot is not easy to assemble, and the pressing stroke is high, which is not suitable for use in a thin keyboard. At the same time, when the cap is pressed, the downward pressure is transmitted to the thin film circuit board made by the double-layer circuit by the elastic member. If the downward pressure is too small, the double-layer line is not easily contacted, so the sensitivity is poor. In addition, the conventional button structure cannot be stored in a non-use state to reduce the structural height. In today's portable computer emphasizing ultra-thin thickness, it is necessary to develop a new button structure to reduce the overall thickness of the portable computer.

The present invention relates to a button structure and a portable computer using the same, which is designed to be lightweight and thin, to reduce the pressing stroke and to improve the sensitivity.

The present invention relates to a button structure that can be switched from a released state to a stored state to reduce the overall height of the button structure.

The present invention relates to a portable computer that can reduce the overall thickness of the portable computer when it is turned off by using a button structure that is reduced in overall height during storage.

According to an aspect of the invention, a button structure is provided, including a key cap, a pivoting assembly, a first support member, a second support member, a smokable member, and a magnetic member.
