Computer keyboard provided with backlight

Abstract

The invention discloses a computer keyboard provided with a backlight. The computer keyboard provided with the backlight comprises a keyboard base body, a plurality of press keys are arranged on the keyboard base body, each press key is composed of a transparent keycap, a movable support and a base board, the top end of the movable supports are connected with the lower sides of the transparent keycaps, the lower ends of the movable supports are arranged on the base boards, silica gel elastic bodies are arranged between the transparent keycaps and the base boards, the base boards are further provided with illuminating lamps which are located below the transparent keycaps, light sent by the illuminating lamps can be shot out from the transparent keycaps, preferably, the illuminating lamps are light-emitting diode (LED) lamps, connecting clamping ports are arranged on the lower sides of the transparent keycaps, the upper ends of the movable supports are clamped in the connecting clamping ports and can be taken out from the connecting clamping ports, overhaul of the press keys is convenient, and a switch controlling turn-on and turn-off of the illuminating lamps is arranged on the keyboard base body and can turn on or turn off the illuminating lamps according to light conditions. The keyboard is provided with the transparent keycaps, the illuminating lamps are installed below the transparent keycaps, the illuminating lamps can be turned on to illuminate the transparent keycaps under the condition that light is insufficient, and input operation of the keyboard is convenient.

Description

technical field [0001] The invention relates to a computer input device, in particular to a computer keyboard with a backlight. Background technique [0002] The early keyboards were almost all mechanical keyboards, to be precise, mechanical contact keyboards, which used electrical contact contacts as joint signs, and mechanical metal springs as elastic mechanisms. This kind of keyboard has a hard feel, long key stroke, quick and crisp change of key resistance, and the feel is very close to that of a typewriter keyboard, so it was very popular at that time. However, the two biggest disadvantages of the mechanical contact keyboard are that the mechanical spring is easily damaged, and The electrical contacts will oxidize after prolonged use, causing the keys to fail. So after the 1990s, mechanical contact keyboards gradually withdrew from the historical stage. At first, it was replaced by electromechanical keyboards. The electromagnetic mechanical keyboard is still a kind o...
