Photoelectric principle-based waterproof keyboard

Abstract

Disclosed is a photoelectric principle-based waterproof keyboard. The photoelectric principle-based waterproof keyboard comprises an integrated elastic key, an upper shell and a lower shell; the elastic key comprises a bottom plate and at least one key body; each key body is elastically connected with the bottom plate; the bottom plate is fixed on the upper shell through a key pressing plate; theupper shell is sealed and fixed in the lower shell; a circuit board is arranged on the lower shell; the key body is electrically connected with the circuit board; each key body is isolated into an independent space by a light-shielding plate; a photosensitive element and a light emitting element corresponding to each independent space are arranged on the circuit board separately; the photosensitive element and the light emitting element are positioned on the two sides of each key body respectively; the upper shell adopts a light-permeating material while the rest structure adopts a non-light-permeating material; when the key body is pressed downwardly, the light from the light emitting part can be shielded; and when the key body is reset, the light from the light emitting part illuminatesthe corresponding photosensitive element. The keyboard can be used in a water-spraying moisture environment, without being intervened by external light rays; and the keyboard has the core part of thelight emitting parts and the photosensitive parts, so that the keyboard has super-long service life.

Description

Technical field [0001] The invention belongs to the technical field of human-computer interaction, and specifically relates to a waterproof keyboard with photoelectric principle. Background technique [0002] When the keyboard is used in the bathroom, toilet, etc. where it is exposed to water and wet, it will inevitably involve the waterproof problem of the keys. The existing keyboards using conductive glue, pot slices, etc. cannot be used for a long time in a wet environment, although the touch keyboard can It is waterproof, but if there are water drops on the surface of the button, it will cause the button to operate incorrectly or even fail to work normally. [0003] In addition, in the use field that does not involve waterproofing, the keyboard of the conductive glue and the pot plate also has a certain limit in the service life. Summary of the invention [0004] In view of the above-mentioned shortcomings of the prior art, the present invention aims to provide a waterproof key...

AI Technical Summary

Problems solved by technology

[0002] When the keyboard is used in wet and wet places such as bathrooms and toilets, it will inevitably involve the waterproof problem of the keys. The existing keyboards using conductive glue, metal pins, etc. It is waterproof, but if there are water droplets on the surface of the button, it will cause misoperation of the button or even malfunction

[0003] In addition, in the field of use that does not involve waterproofing, the keyboard with conductive glue and domes also has certain limitations in terms of service life.
