Thin keyboard composed of soft rubber parts and hard rubber parts

Abstract

The invention relates to a thin keyboard composed of soft rubber parts and hard rubber parts. The thin keyboard is just composed of a hard rubber key fixing plate, soft rubber keys, a printed circuit film and a bottom plate from top to bottom. The soft rubber keys are formed by soft rubber materials in an integral injection molding mode and are connected at intervals to form protruding pressing key bodies, and the protruding pressing key bodies are formed by connection of a top key surface body, an arc-shaped elastic connection body and a bottom key surface from top to bottom; the hard rubber key fixing plate is a plate-shaped body which is formed by hard rubber materials in an integral injection molding mode and is provided with a plurality of key holes; the key holes of the hard rubber key fixing plate are in one-to-one correspondence to the protruding pressing key bodies on the soft rubber keys. Due to the adoption of the structure, the thin keyboard composed of the soft rubber parts and the hard rubber parts has the advantages of being small in part number and low in cost, saving labor cost, and being extremely thin, firm in structure, good in had feeling, waterproof, dustproof and simple in structure.

Description

technical field [0001] The invention relates to the technical field of computer keyboards, in particular to a thin keyboard composed of soft rubber parts and hard rubber parts. Background technique [0002] Along with the development of information industry, computer is widely used day by day, no matter be notebook computer or desktop computer all can not do without computer keyboard, there are some defects in existing scissors structure keyboard: [0003] 1. A large amount of manual assembly is required, and low production efficiency is the most troublesome problem in this industry today; [0004] 2. The structure is not firm, the keycap is easy to shake, and the hand feel is poor; [0005] 3. In the future, all keyboards will develop in the direction of ultra-thin, and the traditional structure is no longer suitable; [0006] 4. The traditional scissor foot structure keyboard cannot be waterproof and dusty, and cannot protect the circuit part from moisture; [0007] 5. ...

AI Technical Summary

Problems solved by technology

[0003] 1. A large amount of manual assembly is required, and low production efficiency is the most troublesome problem in this industry today;

[0004] 2. The structure is not firm, the keycap is easy to shake, and the hand feel is poor;

[0005] 3. In the future, all keyboards will develop in the direction of ultra-thin, and the traditional structure is no longer suitable;

[0006] 4. The traditional scissor foot structure keyboard cannot be waterproof and dusty, and cannot protect the circuit part from moisture;

[0007] 5. When the temperature of the traditional scissors keyboard changes, the slot on the bottom of the keycap and the cylindrical shaft of the scissors bracket are not the same in expansion and contraction, and it is easy to fall off;

[0008] 6. The traditional scissor foot structure keyboard, in the case of accidental extrusion, impact or drop, the slot on the bottom of the keycap and the cylindrical shaft of the scissor bracket are easy to separate;

[0009] However, when soft rubber is used alone to make key cap parts, the soft rubber is easy to deform, and the ability to recover elastic deformation after deformation is not high. Therefore, directly using soft rubber to make a single key cap part cannot realize the recovery of deformation;
