Abstract

The invention provides a light and thin keyboard comprising an elastic pressing layer which comprises a pressing area and an edge. The edge is fixed on a circuit board in a downward bending way. A pressing cavity is formed between the pressing layer and the circuit board. The pressing area is provided with a first surface and a second surface. The first surface is provided with pressing columns which are internally provided with accommodating cavities. The upper openings of the accommodating cavities are arranged on the second surface. Luminous bodies are arranged in the accommodating cavities. Light guide columns are arranged on the luminous bodies. The top ends of the light guide columns are connected with light transmitting keys. The keys are exposed out of the upper part of the second surface. An adhesive layer is adhered on the first surface. Through holes are arranged on the adhesive layer. Reversal sheets are adhered in the through holes. The surfaces of the reversal sheets are adhered with the internal part of the through holes. First static contacts and second static contacts are arranged on the circuit board. Elastic columns are arranged on the first surface. The elastic columns penetrate through the adhesive layer to extent to the surface of the circuit board. Double resetting can be realized; the luminous bodies absorb light energy in the daytime and automatically emit light at night; the light uniformity can be enhanced by the light guide columns so as to be softer; and a light transmitting layer does not need to be arranged so that the structure can be simplified and the light and thin degree can be enhanced.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a light and thin keypad. Background technique [0002] With the continuous development and progress of electronic technology, the design of electronic product components is developing in the direction of high performance and low cost. Therefore, any improvement in electronic products has industrial application value as long as it helps to simplify the structure, facilitate assembly and reduce costs. [0003] Generally, an electronic device, such as a computer, includes a decorative panel and a plurality of button devices fixed on the decorative panel, such as a power button, a sound button, and the like. In many cases, a keypad is used on an electronic device, including a plurality of keys for realizing different functions. LED lights that can be energized and lighted are often added to both sides of the key switch structure, and a light-transmitting layer is adde...
