Backlight crystal key cap applied to computer keyboard

Abstract

The invention relates to the field of keyboards, and especially relates to a backlight crystal key cap applied to a computer keyboard. The backlight crystal key cap comprises a key cap body and a bottom projection light source, the key cap body comprises a pedestal and a crystal cover covering the pedestal, the surface, of the pedestal, facing the crystal cover is provided with a character, and the character is formed in a way that laser can penetrate the crystal cover, and engrave the character on the pedestal to form a character pattern; or the character is formed by die injection moulding and does not need to be engraved or printed, and the pedestal and the crystal cover are made of sizing materials having different transparency and are combined to form an integral structure through double-material injection moulding integral moulding manner. According to the invention, in a conventional technology, the process that the character is achieved by being printed on the surface of the button is changed, under the condition that any printing ink is not employed, the conventional way that after monochromatic injection moulding, the character is printed and then is pasted is improved, seamless combination is achieved, the dustproof and waterproof effect is good, during the laser engraving process, the crystal cover is resistant to laser engraving and is not engraved through by laser, and laser does not engrave the crystal cover; by adjusting the power of a laser beam, the pedestal can be gasified or carbonized, and therefore a character, a symbol or a pattern can be engraved in the pedestal.

Description

technical field [0001] The invention relates to the field of keyboards, in particular to a backlight crystal keycap used on a computer keyboard. Background technique [0002] The traditional computer keyboard keys currently on the market are very convenient to use in a bright environment, but in a dark environment, because the operator cannot see the handwriting and symbols on the keyboard, it cannot be operated flexibly, and after the keyboard is used for a long time, The characters printed on the keyboard will be easily worn due to nail scratches or sweat and other substances, and the handwriting will not be clear, thereby affecting the normal use of the computer keyboard.
