Problems solved by technology

However, due to the wiring or internal structure arrangement in the keyboard, it is necessary to open holes at some specific positions of the backlight module for the wiring or the internal structure to pass through, but the wiring or the internal structure is often thinner than the opening , and its volume cannot completely cover the opening, so there will always be a problem of light leakage at the position of the backlight module relative to the above-mentioned positions

Embodiment Construction

[0046] Such as figure 1 as shown, figure 1 It is a schematic cross-sectional view of the backlight module of the first embodiment of the luminous keyboard of the present invention that has not been pierced. The luminous keyboard 1 of the present invention includes a plurality of keys 2 , a thin film circuit board 3 , a structural support board 5 and a backlight module 4 . The positional relationship is that the thin film circuit board 3 is stacked on the structural support board 5 , and the button 2 passes through an opening 30 of the thin film circuit board 3 to be connected to the structural support board 5 . The backlight module 4 is disposed under the structural support plate 5 . That is, the thin film circuit board 3 , the structural support plate 5 and the backlight module 4 are sequentially arranged from top to bottom.

[0047] Furthermore, the button 2 has a scissors structure 21 , the scissors structure 21 passes through the opening 30 of the thin film circuit boar...

Abstract

The invention provides a luminous keyboard, comprising multiple keys and one backlight module arranged below multiple keys. The backlight module comprises one light blocking plate, one light guiding plate and one reflecting plate, and the light blocking plate, the light guiding plate and the reflecting plate are overlaid in order from top to bottom. The light blocking plate is provided with one first cutting opening and one first cutting opening periphery defined by the first cutting opening, the reflecting plate is provided with one second cutting opening and one second cutting opening periphery defined by the second cutting opening, and one upper surface of the second cutting opening periphery of the reflecting plate passes through one perforation of the light guiding plate to be stuck on one lower surface of the first cutting opening periphery of the light blocking plate. Therefore, when one object passes through the first cutting opening and the second cutting opening, the first cutting opening periphery and the second cutting opening periphery closely cover the object by virtue of respective elastic restoring forces.

Description

technical field [0001] The invention relates to a luminous keyboard, in particular to a luminous keyboard which avoids light leakage. Background technique [0002] A keyboard is an indispensable device for modern people to use a computer. Many keys are arranged on the keyboard for users to press to input commands. [0003] With the improvement of keyboards, keyboards with backlight modules, or generally called luminous keyboards, have appeared. These keyboards are used in indoor lighting environments (such as offices, rooms), and the human eye can clearly recognize the light passing through the bottom of the keyboard upwards. Permeate the light of each key, and present a visual effect. [0004] The backlight module is composed of a light-shielding plate, a light-guiding plate, and a reflector. The light-shielding plate and the reflecting plate sandwich the light-guiding plate, so that the light is restricted to travel in the light-guiding plate and only emits from a specia...
