Description

Keyboard that light energy charged

Technical Field

The utility model relates to the technical field of keyboards, in particular to a light energy charging keyboard.

Background

The wireless keyboard refers to a keyboard with a wireless cable directly connected to a host computer, and the wireless keyboard is communicated with the computer by adopting a wireless technology, so that the constraint of wires is omitted. Because the wireless keyboard is not connected with the host, the wireless keyboard cannot be powered through the host, and the power-off and power-off of the wireless keyboard cannot be realized like a wired keyboard, but a user is required to self-close a power-off switch of the wireless keyboard to power off, the energy supply of the wireless keyboard on the market is generally dry batteries and commercial power rechargeable lithium batteries, and the wireless keyboard has the trouble that the user can not use up electricity occasionally and timely replace batteries or can not use the keyboard because of no power charging in the scenes of going on a business trip, going out, outdoor parties and the like.
