Embodiment Construction

[0038] figure 1 is an exploded perspective view of the first embodiment of the button device of the present invention, figure 2 It is another exploded perspective view of the first embodiment of the button device of the present invention. Such as figure 1 and figure 2 As shown, in this embodiment, the button device 1 includes a substrate 10 , a keycap 20 , a balance bar 30 and a film layer 40 . The keycap 20 is disposed above the substrate 10 , the balance bar 30 is disposed between the substrate 10 and the keycap 20 , and the film layer 40 is disposed on the substrate 10 .

[0039] In one embodiment, the substrate 10 is preferably a metal plate body. For example, the substrate 10 is made of iron, aluminum or other alloy materials, and has better structural strength, but this is not limited. The substrate 10 It can also be made of other hard materials.

[0040] Such as figure 1 and figure 2 As shown, the keycap 20 can be connected above the substrate 10 by a connecti...

Abstract

A button device includes a substrate, a keycap, balance bars and a film layer. The key cap is disposed at the upper portion of the substrate, the balance bars are arranged between the substrate and the key cap, each balance bar comprises a shaft lever and a side bar extended from the lateral direction of the shaft lever, and each side bar has a tail end far away from the shaft lever. The film layer is arranged on the substrate, the film layer is provided with a cutting structure, the cutting structure is adjacent to the tail ends of the side bars, the film layer comprises a flexible spacing area located at one side of the cutting structure, the side bars of the balance bars penetrate the cutting structure, and the tail ends of the side bars are butted against the flexible spacing area.

Description

technical field [0001] The invention relates to a keyboard assembly, in particular to a key device. Background technique [0002] A keyboard is a very common input device at present, and it is usually used with electronic devices, such as desktop computers, notebook computers, smart phones or tablet computers, and so on. At present, in order to make the keys of the keyboard more evenly transmit power after being pressed, a balance bar is usually installed inside the key, so that the pressing force is transmitted to the corner through the balance bar to make the keys drop evenly. [0003] The key structure of the existing keyboard mainly includes a metal bottom plate, a keycap and a balance bar. The balance bar is assembled between the keycap and the metal bottom plate. A fixed plate extends upward from the bottom plate, and the fixed plate is provided with a slide groove, and the end of the balance bar is passed through the slide groove of the fixed plate to combine with th...
