Maglev button device

The present invention relates to a button device, and more particularly to a maglev button device that utilizes the principle of maglev.

Generally, the definition of a keyboard is a set of buttons for operating a machine, and is a group of buttons arranged in a systematic manner. The most traditional buttons are mechanical buttons, which are designed on a circuit board. A plurality of dual-in-line package (DIP) switches are arranged, each DIP switch corresponds to a button, and the magnitude of the stress required for pressing is adjusted by adjusting the stress of the spring. Since the keyboard uses a DIP switch composed of a plurality of metal reeds and springs, the noise is large during use, and the key stroke is long, which is not suitable for high-speed input. On the other hand, it uses plural DIP switches make the thickness of the keyboard difficult to reduce, occupying a considerable amount of space in electronic devices, and are not suitable for deployment on portable electronic products, such as ultra-thin notebooks and smart phones. on. Therefore, a thin-film keyboard has been developed for the thin design of portable electronic products, which has low cost, simple structure, easy mass production, low noise during use, and short button stroke, compared with the conventional mechanical type. The keyboard is more suitable for high-speed input, and the elastic conductive rubber is used as a medium for the upper and lower electrodes of the button to be activated to trigger the function of the button, and the button can be bounced back to the initial position by the characteristics of the rubber material after the button is pressed. Pressed again.

However, the rubber has a problem of deterioration, which is easily damaged after repeated bending and pressing, and loses the elastic force; on the other hand, the keyboard cannot reduce the height of the button when it is not in use, and the storage of the keyboard and the design of the portable electronic product are , resulting in thinning and portability restrictions; therefore, Chinese Patent No. CN 103065844 B proposes a magnetic button and its keyboard, It does not have the problem of repeated extrusion and is prone to deterioration and loss of elasticity, and has a better service life.

However, the magnetic floating keyboard of the prior art does not have a sense of passage when pressed (that is, the feeling that the damping changes with the position of the pressing stroke), which is more laborious when pressed, and it is difficult for the user to judge whether the pressing is effective pressing or not. The result of uninput or repeated input causes inconvenience in use and poor user experience; on the other hand, the magnetic floating keyboard of the prior art is difficult to reduce the height of the button when it is not in use, and it is difficult to achieve convenient storage and convenient carrying. .
