Benefits of technology

The keyboard device achieves a balance of reduced manufacturing costs and user feedback similar to mechanical switches, providing a slim and functional input experience.

Problems solved by technology

The resilience element and the sleeve may interfere with each other.
While the plunger-type support shaft is moved upwardly or downwardly relative to the sliding groove, the resilience element and the stopping structure interfere with each other, so that the key structure generates an operating sound.

Embodiment Construction

[0037]Please refer to FIGS. 5, 6, 7A and 7B. FIG. 5 is a schematic top view illustrating a keyboard device according to a first embodiment of the present invention. FIG. 6 is a schematic perspective view illustrating a portion of the keyboard device as shown in FIG. 5. FIG. 7A is a schematic exploded view illustrating a portion of the keyboard device as shown in FIG. 5 and taken along a viewpoint. FIG. 7B is a schematic exploded view illustrating a portion of the keyboard device as shown in FIG. 5 and taken along another viewpoint. For succinctness, only one key structure is shown in FIGS. 6, 7A and 7B. The keyboard device 3 comprises plural key structures 30, a base plate (not shown), a membrane wiring board 32 and an elastic element 31. The membrane wiring board 32 is disposed on the base plate. The elastic element 31 is arranged between the membrane wiring board 32 and the key structures 30. These key structures 30 are classified into some types, e.g., ordinary keys, numeric keys...

Abstract

A keyboard device includes a key structure, a membrane wiring board and an elastic element. The elastic element is arranged between the key structure and the membrane wiring board. The key structure includes a sleeve, a plunger-type support shaft, a keycap and a resilience element. The plunger-type support shaft is movable upwardly or downwardly relative to the sleeve. When the keycap is depressed in response to an external force, the resilience element and the sleeve interfere with each other. Consequently, the keyboard device provides the operating sound and the operating feedback like a mechanical switch.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an input device, and more particularly to a keyboard device.BACKGROUND OF THE INVENTION[0002]Generally, the widely-used peripheral input device of a computer system includes for example a mouse device, a keyboard device, a trackball device, or the like. Via the keyboard device, characters or symbols can be inputted into the computer system directly. As a consequence, most users pay much attention to the keyboard devices.[0003]Hereinafter, the structure and function of a conventional keyboard device with a mechanical key structure will be described with reference to FIGS. 1 and 2. FIG. 1 is a schematic cross-sectional view illustrating a conventional keyboard device with a mechanical key structure. FIG. 2 is a schematic cross-sectional view illustrating the mechanical switch of the conventional keyboard device of FIG. 1, wherein a keycap of the mechanical key structure is depressed. For succinctness, only one mechanical key...
