Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 and 4, a backlight keyboard according to an embodiment of the present invention includes a bottom plate 1, a hook portion 11, a key cap 3, and a light emitting module 2; the bottom plate 1 is provided with a bearing surface for bearing all relevant components in the backlight keyboard, the bearing surface is provided with a plurality of clamping hook parts 11 for clamping the keycaps, the distribution mode of the clamping hook parts 11 on the bottom plate 1 is the same as that of the keys of the keyboard, the keycaps 3 are clamped in the clamping hook parts 11, the clamping hook parts and the keycaps are mutually matched to form the key function of the backlight keyboard, and the clamping hook parts 11 are diversified in shape and used for being matched with the keycaps 3 in different shapes.

In the present embodiment, the base plate 1 is made of metal, but other materials may be used.

In this embodiment, after each hook portion 11 is disposed on the bottom plate 1, a gap is disposed between the hook portion 11 and the bottom plate 1, and the light emitting module 2 is disposed in the gap and just located between the keycap and the bottom plate 1.

Referring to fig. 2-3, the light emitting module 2 includes an insulating layer 20, a conductor line 21, and an LED22; the insulating layer 20 is laid on the bearing surface of the bottom plate 1, and the conductor circuit 4 is arranged in the area where the insulating layer 20 is laid, so that the bottom plate 1 made of metal and the conductor circuit 21 can be well prevented from generating short circuit, and the conductor circuit 21 can be ensured to work normally to supply power to the LED22 to enable the LED22 to emit light.
