The above-mentioned luminous keyboards respectively disclose a variety of luminescent backplanes such as electroluminescent sheets (Electroluminescent Sheet) and optical fiber panels (Optical Fiber panels) are added above or below the bottom plate of the keyboard, so that the keys located above the luminescent backplane can shine through the light. For the user to identify the location. Although this kind of luminous keyboard can make the whole keyboard evenly luminous through a single luminous back panel, compared with the above-mentioned luminous keyboard arranged inside the keys, it can indeed reduce internal parts and facilitate assembly, and the consumption of electroluminescent boards and optical fiber boards The power is extremely low, which is conducive to long-term use. In addition, such as Taiwan Patent No. I269333 and U.S. Application No. 11/288,258, a keyboard with a backlight structure is disclosed, and a light source transmission space is defined between the bridge plate and the bottom plate below, and At least one light guide part is provided on the bridge plate corresponding to the place on the keyboard part where the light source is to be emitted to the light source conduction space, and the light guide part receives the emitted light source that enters the light source conduction space and guides it into the keyboard part to form the keyboard. backlit architecture.

Detailed ways

Relevant detailed description and technical content of the present utility model, cooperate schematic diagram to illustrate as follows now:

Please refer to Fig. 1, Fig. 2 and Fig. 3-1, which are partial decomposition, A-A structure section and B-B structure section schematic diagram of a preferred embodiment of the utility model, as shown in the figure: the utility model is a light-emitting structure The keyboard includes a keyboard portion 10 disposed in a housing body 40 and a base plate 20 for carrying the keyboard portion 10 . The keyboard portion 10 includes a plurality of pressing parts 11 for pressing by a user, and a linkage mechanism 12 disposed under the pressing surfaces of the pressing parts 11 and providing a displacement stroke of the pressing parts 11 according to the direction of the pressing force. The linkage mechanism 12 has an elastic element 13 to make the pressing member 11 reciprocate up and down. The base plate 20 has an assembly portion 21 for assembling the other end of the linkage mechanism 12 , so that the keyboard portion 10 is disposed on the base plate 20 . In this embodiment, the substrate 20 includes a bridge board 22 with the assembly portion 21 and a circuit board 23 triggered by the displacement of the pressing member 11 to generate a command signal.

The surface side of the substrate 20 has at least one light guide groove 24, and a light channel for light source transmission is formed in the light guide groove 24. The formed light-emitting spaces 31 have a mutual light-conducting relationship. A light emitter 30 is disposed on the substrate 20 to generate light input into the light guide groove 24 so that the light travels along the direction of the light channel. The light emitter 30 can be placed at the end of the light guide groove 24, as shown in FIG. 1, or can be arranged in the light guide groove 24, as shown in FIG. middle.

At least one inner wall surface in the light guiding groove 24 is a reflective surface. In this embodiment, please refer to FIG. 3-1 , the light guide groove 24 has two reflective surfaces, namely a first reflective surface 241 and a second reflective surface 242 . In order to make the light in the light guide groove 24 diffuse into the surrounding light-emitting space 31, the light guide groove 24 is in a V-shaped or U-shaped structure, and the first reflective surface 241 or the second reflective surface 242 are opposite to each other. There is a reflective angle θ on the surface of the substrate 20 , and the reflective angle θ can be between 180° and 0°, and a reflective layer 243 is provided on the first reflective surface 241 and the second reflective surface 242 . When the light emitter 30 generates light and enters it into the light guide groove 24, on the one hand, the light can be reflected on the first reflective surface 241 due to the reflection angle of the first reflective surface 241 or the second reflective surface 242. Pass back and forth with the second reflective surface 242, so that the light moves along the direction of the light guide groove 24 to the remote; The light-emitting space 31 formed between 20, the reflection angle θ can also reflect the light and the first reflective surface 241 or the second reflective surface 242 into the light-emitting space 31, so that the pressing member 11 has brightness. In addition, only one inner wall surface of the light guiding groove 24 may be the reflective surface 246, as shown in FIG. 3-2. In this embodiment, there is a reflection angle θ between the reflective surface 246 and the substrate 20 The reflective angle θ can be between 180° and 0°, and a reflective layer 243 is also disposed on the reflective surface 246 . When light enters the light guiding groove 24 , the light can be obliquely reflected to the pressing member 11 in the light emitting space 31 through the reflective surface 246 .

When the light is generated through the light emitter 30 , the brightness may decrease due to the farther transmission distance. Therefore, in another embodiment of the present invention, as shown in FIG. 5 , the depth of the light guiding groove 24 decreases as the distance from the light emitter 30 increases. That is to say, when the light enters the light guide groove 24, the depth of the light guide groove 24 becomes shallower as the distance from the light emitter 30 is farther away. In this way, the reflected light in the light guide groove 24 The space becomes smaller, making it easier for light to diffuse into the luminous space 31 , so that the luminous state of the entire keyboard is uniform. In this embodiment, the light guiding groove 24 has at least one smooth slope 244 to adjust the depth of the light guiding groove 24 . Alternatively, the light guiding groove 24 may have at least one stepped structure 245 (as shown in FIG. 6 ), so that the farther the distance from the light emitter 30 is, the shallower the depth of the light guiding groove 24 is.

To sum up, since the keyboard with light-emitting structure of the present invention only needs to be equipped with a few light-emitting devices, the light can be diffused in the light-emitting space below the keyboard through the light-guiding groove, which can reduce the number of light-emitting components and reduce the number of keyboards. The overall thickness, in order to achieve the purpose of thinning. In addition, the depth of the light-guiding groove is adjusted according to the change of the distance from the light emitter, so that the light-emitting space has uniform brightness.

The utility model has been described in detail above, but the above is only a preferred embodiment of the utility model, and should not limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made according to the claims of the utility model should still fall within the scope of the patent of the utility model.
