Embodiment Construction

[0062] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments. The inventive idea of ​​each embodiment of the present invention needs to consider the following basic limitations and solve related problems: (1) If the button is to achieve hand feel feedback, it is intuitively necessary to additionally set up a feedback mechanism to physically connect the pressing member to provide an appropriate feedback feel during use (2) The aforementioned feedback mechanism not only increases the complexity of the button structure, but also the feedback mechanism itself is easily worn due to repeated operations due to the physical connection; (3) when using the optical switch button, if the button has no other elasticity The component provides reset force, and the embodiments of the present invention must be able to provide pressing resistance as...

Abstract

The invention discloses a key structure. The key structure comprises a base, a key plate, a first magnetic action piece and a second magnetic action piece, a containing space is formed in the base, and a connecting part is arranged on the upper surface of the base. The key board is provided with a pressing end, a resetting end and a pivoting part; the pivot joint part is located between the pressing end and the reset end, and the pivot joint part is in pivot joint with the connecting part. The first magnetic acting piece is arranged at the reset end; the second magnetic action piece is arranged on the base, and the second magnetic action piece is arranged corresponding to the first magnetic action piece. The key structure is configured in a way that the first magnetic acting piece and the second magnetic acting piece attract or repel each other through magnetic force so as to provide or increase or decrease the pressing resistance of the pressing end.

Description

technical field [0001] The present invention relates to keys, and in particular, the present invention relates to a key structure that provides a pressing feedback feel through the configuration of a pair of magnetic components. Background technique [0002] The key structure generally includes a trigger switch and a pressing member (such as a key board or a key cap) disposed above the trigger switch; common trigger switches include mechanical micro switches, membrane switches and optical switches. The trigger point of the mechanical micro switch has a clear pressing resistance, allowing the user to feel the pressing feedback. Membrane switches have less tactile press feedback. [0003] Mechanical micro switches and membrane switches are subject to continuous wear and tear during use, resulting in a short lifespan. When the optical switch is triggered, there will be no movable or deformed parts inside the optical switch, which can effectively avoid wear and tear. However,...
