Embodiment Construction

[0022] see Figure 1 to Figure 3 . figure 1 It is a schematic diagram of a key structure 1 according to an embodiment of the present invention, figure 2 is the exploded view of key 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 switching key of a keyboard, but the present invention is not limited thereto, for example, it is applied to other function keys or letter and number keys. The key structure 1 includes a bottom plate 10 , a keycap 12 , a lifting mechanism 14 , a film circuit board 16 , an elastic round protrusion 18 , a light emitting unit 20 , a light-proof cover 22 and a flexible light-proof tubular member 24 . The keycap 12 is arranged on the base 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 base plate 10, so that the keycap 12 can move up and down relative to t...

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 are more printed with text and patterns on the surface of the keycap to remind the user of the function of the button. In addition, lights (such as LEDs) are set on the frame of the structure to remind the user of the specific function of the keyboard, such as upper and lower case. Toggle hints, numpad area enable, window scroll lock, etc. At present, some keyboards directly set the indicator lights of some specific functions on the function keys that switch the functions, such as the upper and lower case switching keys. At this time, the LED is fixedly arranged under the keycap, and the keycap has a corresponding light-transmitting part for the light emitted by the LED to penetrate, thereby achieving an indication effect. However, generally, the light emit...
