Embodiment Construction

[0022] See Figure 1 to Figure 3 . figure 1 Is a schematic diagram of a key structure 1 according to an embodiment of the present invention, figure 2 Is the exploded view of button structure 1, image 3 It is a cross-sectional view of the key structure 1 along the line X-X. In this embodiment, the key structure 1 is a case switch key of the keyboard, but the present invention is not limited to this, for example, it is applied to other function keys or letter and number keys. The key structure 1 includes a bottom plate 10, a key cap 12, a lifting mechanism 14, a thin film circuit board 16, an elastic dome 18, a light-emitting unit 20, an opaque cover 22 and a flexible opaque tubular member 24. The keycap 12 is disposed on the bottom plate 10 and has a light-transmitting portion 122 and a bottom surface 124. The lifting mechanism 14 is connected between the bottom surface 124 and the bottom plate 10, so that the keycap 12 can move up and down relative to the bottom plate 10 thro...

Abstract

The invention provides a key structure. The key structure comprises a bottom board, a keycap, a lifting mechanism, a light emitting unit, a light-proof cover and a flexible light-proof tubular part, wherein the keycap can vertically move through the lifting mechanism relative to the bottom board; the light emitting unit is arranged below the light transmission part of the keycap and used for emitting light; the light-proof cover covers the light emitting unit so that light passes through an opening of the light-proof cover and then is emitted out of the light-proof cover towards the keycap; the flexible light-proof tubular part is arranged between the keycap and the light emitting unit, and the open end of the flexible light-proof tubular part surrounds the light-proof cover so as to prevent light from being leaked; when the keycap moves towards the bottom board, the flexible light-proof tubular part is restrained by the keycap and the light-proof cover and then warps and deforms, and however light still can pass through the flexible light-proof tubular part and emit out of the light-proof cover towards the keycap. The key structure can effectively prevent light from being leaked from the periphery of the keycap.

Description

Technical field [0001] The present invention relates to a key structure, in particular to a key structure with light indication. Background technique [0002] The keyboard is a common input device. Traditional keyboards have more text and patterns printed on the surface of the keycaps to remind the user of the function of the key. In addition, lights (such as LED) are set on the structure frame to remind the user of specific keyboard functions, such as uppercase and lowercase. Switch prompts, enable numeric keypad area, window scroll lock, etc. At present, some keyboards directly set the indicator light of some specific functions on the function keys for switching that function, such as the uppercase and lowercase switch keys. At this time, the LED is fixedly arranged under the key cap, and the key cap has a corresponding light-transmitting part for the light emitted by the LED to penetrate, thereby achieving an indication effect. However, the light emitted by the general LED d...
