In order to achieve the purpose, the invention adopts the technical scheme that: a backlit keyboard, comprising:

the base plate is provided with a bearing surface, and the bearing surface is provided with a plurality of clamping hook parts;

the key cap is clamped in the clamping hook part and plays a key pressing role after being matched with the clamping hook part; and

the light-emitting module is arranged between the keycap and the bottom plate and used for providing backlight for the keycap; wherein, the light emitting module includes:

an insulating layer laid on the base plate;

the conductor circuit is arranged in the area where the insulating layer is laid on the bottom plate;

and the at least one LED is arranged in the conductor circuit and emits light after being conducted with the conductor circuit.

Furthermore, the bottom plate is made of metal.

Further, the insulating layer is made of insulating glue or plastic.

Further, the LED is attached in the conductor circuit.

Further, the thickness of the LED between the lower surface of the bottom plate is 1-1.5mm.

Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages:

the backlight keyboard provided by the scheme of the invention has a simple integral structure, the bottom plate not only plays a supporting role, but also the conductor circuit is directly arranged on the bottom plate through the insulating layer, and then the conductor circuit is conducted with the LED and then emits light.

FIG. 2 is a schematic structural diagram of a light emitting module according to an embodiment of the present invention;

FIG. 3 is a top view of FIG. 2;

FIG. 4 is a schematic view of the key cap, the hook and the light-emitting module separated according to an embodiment of the present invention;

wherein: the LED light source comprises a base plate 1, a light emitting module 2, a keycap 3, a clamping hook part 11, an insulating layer 20, a conductor circuit 21 and an LED22.

Detailed Description

The invention is described in further detail below with reference to the 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 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 a metal material, 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 key cap 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.

The LED22 is attached to the surface of the conductor circuit 21 and communicated with the conductor circuit 21; wherein, one or more quantity LED is placed to every key cap below for be the state of being shaded in the keyboard, including two LED22 in this embodiment, set up relatively on conductor circuit 21.

After the backlight keyboard in the embodiment is assembled, because the conductor line 21 of the LED is directly laid on the bottom plate 1 through the insulating layer 20, and then the LED emits light through the conductor line 21, the whole keyboard is in a backlight state, the thickness of the whole backlight keyboard is thinner, and the thickness from the LED22 to the lower surface of the bottom plate 1 is only 1-1.5mm, which is thinner than the thickness of the existing keyboard; the bottom plate 1 in this embodiment serves as a support for the LED and the conductor circuit, and the bottom plate 1 also supports the keycap through the hook 11.

As a further preferred embodiment, the insulating layer 20 includes, but is not limited to, an insulating paste as long as it can perform an insulating function.

The backlight keyboard disclosed by the invention is simple in integral structure, the bottom plate not only plays a supporting role, but also the conductor circuit is directly arranged on the bottom plate through the insulating layer, and then the conductor circuit is used for conducting the LED and then emitting light.

The above is only a specific application example of the present invention, and the protection scope of the present invention is not limited in any way. The technical solutions formed by using equivalent transformation or equivalent substitution are all within the protection scope of the present invention.
