Problems solved by technology

Among them, the silicone soft keyboard is made of medical-grade silicone material for the panel and base. Due to the elasticity of the silicone, the keyboard can be curled arbitrarily, which meets the requirements of portability. It is suitable for harsh conditions such as high temperature, and the production cost is high due to the use of medical silica gel

Embodiment 1

[0026] Put the cotton into a tube furnace, pass the protective gas, raise the temperature to 800°C at a rate of 2°C / min, and then perform high-temperature carbonization treatment at 800°C for several hours to obtain a whole piece of carbon fiber, and then carefully cut it with a blade Cut into 4 blocks with uniform thickness and small area difference, remove the insulation of the wire and insert it into the carbon fiber, use a conductive metal gel to make it fully contact with the carbon fiber, and then pour PDMS or PDVF base solution, do not make it submerge the carbon fiber, vacuum debubbles and then cure for 4 hours, then splice the two and a half keyboards together.

Embodiment 2

[0028] Put the vacuum-freeze-dried bacterial cellulose into a tube furnace, raise the temperature to 1000°C at a rate of 5°C / min, and then carry out high-temperature carbonization treatment at 1000°C for 2 hours to obtain a whole piece of carbon fiber, and then use a blade to Carefully cut it into 4 blocks with uniform thickness and small area difference, remove the insulation of the wire and insert it into the carbon fiber, use a conductive metal gel to make it fully contact with the carbon fiber, and then place it on a plastic of any shape The PDMS or PDVF base solution in the mold should not be covered with carbon fiber. After vacuum removal of air bubbles, cure for 3 hours, and then splice the two half-keyboards together.

Embodiment 3

[0030] Waste cotton wool such as clothes or quilts is subjected to high-temperature carbonization treatment at 900°C for 4 hours with protective gas to obtain a whole piece of carbon fiber, and then carefully cut it into 4 pieces with uniform thickness and small area difference with a blade Shape, remove the insulation of the wire and insert it into the carbon fiber, use a conductive metal gel to make it fully contact with the carbon fiber, and then pour PDMS or PDVF base solution into a plastic mold of any shape, do not let it submerge the carbon fiber, vacuum After removing air bubbles, carry out curing treatment for 5 hours, and then splice the two and a half keyboards together.

Abstract

The invention discloses a method for preparing a curly keyboard. Firstly, carbon fiber is carbonized at high temperature, connected with an electrode, put into a plastic mold of any shape, then poured into a PDMS or PDVF base solution, debubbled and solidified in a vacuum, and connected with a single-chip microcomputer as the core. keying circuit. The invention utilizes the excellent elastic characteristics and electrical conductivity of the elastic conductor to produce a keyboard with a simple structure, light and thin, no mechanical loading device, the keyboard base material is transparent, can be twisted arbitrarily, and has excellent waterproof, fireproof, high temperature resistance, etc., surpassing the traditional keyboard. characteristics, so that it can be used in aerospace, marine exploration and other fields.

Description

technical field [0001] The invention relates to the field of computer peripheral equipment and also belongs to the field of electronic materials and devices, in particular to a method for preparing a curled keyboard. Background technique [0002] For a long time, the structure and even the shape of the keyboard have always been in the traditional way, that is, the panel and the base are made of hard materials such as plastic, and the two parts are combined by means of plastic hooks or metal screws. Due to the use of hard materials, the keyboard will be damaged due to excessive pressure deformation. At the same time, the existing keyboards uniformly adopt the traditional QWER key position setting method. This key position setting makes the keyboard shape a long rectangle, so it is very inconvenient to carry. For consumers who have special requirements for the keyboard, they will Always carry the keyboard with you, the lack of portability of the traditional keyboard will affe...
