Embodiment Construction

[0033] The invention provides a key structure with mute design and a keyboard device with the key structure. Specifically, the button structure of the present invention may be a button structure of a computer keyboard, but it is not intended to be such. The button structure of the present invention can be buttons, number keys, etc. of other electronic devices. The key structure of the present invention can be any key structure with a joint, especially a key structure with a joint connected to a balance bar, such as a multiple key, but not limited thereto. Hereinafter, taking a computer keyboard as an example, details of the key structure of the embodiment of the present invention will be described in detail with reference to the drawings.

[0034] Such as Figure 1A and Figure 6A As shown, in one embodiment, the button structure 100 / 200 of the present invention includes a keycap 110, a balance bar 122 / 124, a bottom plate 130 and a buffer sheet 140, wherein the keycap 110 is...

Abstract

The invention relates to a button structure. The button structure comprises a keycap, balance rods, a base plate, and a buffer plate, wherein the keycap comprises combination portions and a lower surface, the combination portions protrude from the lower surface, and when the keycap is pressed, the keycap moves downwardly to a decrease position; the balance rods are connected to the combination portions, and when the keycap is positioned at the decrease position, the lower points of the combination portions are lower than the balance rods; the base plate is arranged below the keycap, the base plate comprises recessed spaces corresponding to the combination portions, the buffer plate is arranged on the base plate, the buffer plate covers the recessed spaces and comprises deformable portions corresponding to the recessed spaces, and when the keycap moves to a lower position towards the base plate, the lower points of the combination portions are abutted against the deformable portions, and the deformable portions extend into the recessed spaces. According to the buffer design of the button structure, buffer elasticity can be provided during button operation, noises generated by direct collision with the base plate of the keycap can be avoided or reduced, and a multilayer structure of a membrane switch forms the buffer design so that the material cost is not increased, and the function of noise reduction can be effectively performed.

Description

technical field [0001] The present invention relates to a key structure, in particular, the present invention relates to a key structure with mute design and a keyboard device with the key structure. Background technique [0002] The keycaps of multiple keys (such as space (Space) key, carriage return (Enter) key, uppercase and lowercase switching (Caps Lock) key, displacement (Shift) key, etc.) of the keyboard device have a larger aspect ratio, so usually A balance bar is added to improve the structural strength of the keycap. Furthermore, with the setting of the balance bar, even if the user presses the non-central position of the keycap, the multiplier key will not be tilted during the pressing process. The balance bar is generally connected to the bottom of the keycap by engaging with the joint part protruding from the lower surface of the keycap. When the user presses the keycap, along with the downward movement of the keycap, usually the protruding joint portion belo...
