Key structure and portable computer using the same

Abstract

The invention provides a key structure and a portable computer using the same. The key structure includes a key cap, a bridge assembly, a first supporting part, a second supporting part, an attractable element and a magnet. The bridge assembly includes first and second hinge parts. One end of the first hinge part has a first link bar, and the other end has a first pivot coupling portion and a first shaft having a first connecting portion. One end of the second hinge part has a second link bar, and the other end has a second pivot coupling portion and a second shaft having a second connecting portion coupled to the first connecting portion. The two connecting portions are engaged with each other to connect the first and second hinge parts. The first and second supporting parts are respectively coupled to both ends of the shaft fixing portion. The attractable element is disposed below the bridge assembly and the attractable element has a first and second end movable relative to an axis to a respective first and second attractable sites. The magnet may be moved back and forth to a position below the first or second attractable position, the first or second end of the attractable element being magnetically attracted to move to the first or second attractable position when the magnetic element is respectively below the first or second attractable position.

Description

technical field [0001] The invention relates to a button structure, and in particular to a lightweight and thin-designed button structure and a portable computer using the button structure. Background technique [0002] The existing key structure adopts an elastic member to provide an elastic restoring force of the key cap, and supports the key cap with a scissor foot structure, so that the key cap can return to the position before being pressed. However, the scissor foot structure is not easy to assemble, and the pressing stroke is relatively high, so it is not suitable for thin keyboards. At the same time, when the push cap is pressed, the downward force needs to be transmitted to the film circuit board made of double-layer circuit through the elastic member. If the downward force is too small, it will not be easy to make the double-layer circuit contact, so the sensitivity is poor. In addition, the existing button structure cannot be stored in the non-use state to reduce...

However, the scissor foot structure is not easy to assemble, and the pressing stroke is relatively high, so it is not suitable for thin keyboards

At the same time, when the button cap is pressed, the downward force needs to be transmitted to the film circuit board made of double-layer circuit through the elastic member. If the downward force is too small, it will not be easy to make the double-layer circuit contact, so the sensitivity is poor.

In addition, the existing button structure cannot be stored in the non-use state to reduce the height of the structure. Today, as portable computers emphasize ultra-thin thickness, it is necessary to develop a new button structure to reduce the overall thickness of the portable computer
