Abstract

A key module with energy storage function includes a transparent key unit, a sun cell, and an elastic unit. The transparent key unit has a plurality of transparent microstructures. The sun cell is disposed under a bottom side of the transparent key unit, and the sun cell has a light-receiving face facing the transparent key unit. The elastic unit is disposed under a bottom side of the sun cell. Therefore, the transparent microstructures of the transparent key unit guide and transmit external light sources onto the light-receiving face of the sun cell in order to increase light source on the light-receiving face.

Claims

a transparent key unit having a plurality of transparent microstructures;

a sun cell disposed under a bottom side of the transparent key unit, wherein the sun cell has a light-receiving face facing the transparent key unit; and

an elastic unit disposed under a bottom side of the sun cell;

wherein the transparent microstructures of the transparent key unit guide and transmit external light sources onto the light-receiving face of the sun cell in order to increase light source on the light-receiving face.

2. The key-module as claimed in claim 1, wherein the transparent key unit is composed of a plurality of key bodies, and the elastic unit is composed of a plurality of elastic bodies corresponding to the key bodies.

3. The key module as claimed in claim 1, wherein the transparent key unit has a plurality of opaque patterns, opaque symbols, opaque words or opaque numerals formed on a top surface thereof.

4. The key module as claimed in claim 1, wherein the transparent key unit has a plurality of opaque patterns, opaque symbols, opaque words or opaque numerals formed on a bottom surface thereof.

5. The key module as claimed in claim 1, wherein the transparent microstructures are disposed on a top surface or a bottom surface of the transparent key unit.

6. The key module as claimed in claim 1, wherein the transparent microstructures are prismatic structures or half round structures.

7.
