Problems solved by technology

[0004] However, as shown in FIG. 1, the shape of the light guide plate 26 is too complicated, so it is very difficult to manufacture and shape. At the same time, due to the structure of the light guide plate 26, uneven light emission will occur in the central area of ​​the keycap 24. Phenomenon, so that the luminous effect of the keycap 24 is greatly reduced

[0050] For ease of description, the present invention is described in detail with a computer keyboard structure having a scissors-like connection mechanism. Of course, the present invention is also applicable to keyboard structures of mobile phones and personal digital assistants (PDAs).

[0051] see figure 2 The keyboard structure 100 of this embodiment mainly includes a bottom plate 110 , a light guide 120 , a thin film circuit board 130 , a key assembly 140 and a light emitting component 150 . The light guide 120 is disposed on the bottom plate 110 . The thin film circuit board 130 is disposed on the light guide 120 . The button assembly 140 is disposed on the thin film circuit board 130 and has a key cap 141 and a transparent elastic body 142 . Meanwhile, the transparent elastic body 142 is located between the key cap 141 and the thin film circuit board 130 . The light-emitting component 150 is arranged on one side of the light guide 120 and is located under the thin fi...

[0058] In this embodiment, components that are the same as those in the first embodiment are marked with the same symbols.

[0059] see image 3 , the keyboard structure 100' of this embodiment also includes a bottom plate 110, a light guide 120, a thin film circuit board 130, a key assembly 140 and a light emitting component 150. However, the light guide body 120 has a concave portion 123 , and the light emitting component 150 is disposed in the concave portion 123 .

[0060] Likewise, the light emitted by the light-emitting component 150 can be output or transmitted to the elastic body 142 and the keycap 141 through the conduction of the light guide body 120 and the reflection between the reflective layers 121 , so that the keycap 141 emits light evenly.

[0061] The configurations and functions of other components of this embodiment are the same as those of the first embodiment, so details will not be repeated here.

[0063] In this embodiment, components that are the same as those in the first embodiment are marked with the same symbols.

[0064] see Figure 4The keyboard structure 100" of this embodiment also includes a bottom plate 110, a light guide 120, a thin film circuit board 130, a key assembly 140, and a light-emitting component 150. However, the light guide 120 has a concave portion 124, The light-emitting component 150 is disposed in the concave portion 124 . In addition, another circuit board 170 is disposed under the bottom plate 110 . The light-emitting component 150 is electrically connected to the circuit board 170 under the bottom plate 110 to obtain power.

[0065] The keyboard structure 100 ″ of this embodiment is very similar to the keyboard structure 100 ′ of the second embodiment. The concave portion 124 of the light guide 120 of the present embodiment faces the bottom plate 110 , while the light guide of the second embodiment The concave portion 123 of 120 faces the...

Abstract

The keyboard structure fids one base board, one light conductor, one thin film circuit board, one button assembly and one light-emitting assembly. The light conductor is set on the base board, and the thin film circuit board is set on the light conductor. The button assembly is set on the thin film circuit board and has one key cap and one elastic body, which is between the key cap and the thin film circuit board. The light-emitting assembly is near the light conductor and below the thin film circuit board, and the light the light-emitting assembly emits is conducted to the elastic body and the key cap via the light conductor.

Description

technical field [0001] The invention relates to a keyboard structure, in particular to a keyboard structure which can make the lighting effect of keys more uniform. Background technique [0002] In general, in order to diversify the keyboards applied to notebook computers or mobile phones, etc., luminous keyboards have become a popular trend. [0003] Please refer to FIG. 1 , a traditional luminous keyboard structure 2 mainly includes a bottom plate 21 , a film circuit board 22 , an elastic component 23 , a keycap 24 , a light source 25 and a light guide plate 26 . The light guide plate 26 is disposed on the bottom plate 21 and the thin film circuit board 22 , and the light source 25 is disposed between the thin film circuit board 22 and the light guide plate 26 . The light emitted by the light source 25 can be transmitted through the light guide plate 26 to make the keycap 24 produce a luminous effect. [0004] However, as shown in FIG. 1, the shape of the light guide pla...
