Flexible fabric keyboard

Abstract

The invention relates to a flexible fabric keyboard which comprises a key layer, an upper function layer, an isolation layer, a lower function layer and a protection layer, wherein the key layer, the upper function layer, the isolation layer, the lower function layer and the protection layer are sequentially arranged from top to bottom; key symbols of the keyboard are marked on the surface of the key layer; open holes corresponding to the key symbols of the key layer are arranged on the isolation layer; and a single thread of upper spun conductive yarn and a single thread of lower spun conductive yarn are respectively arranged on the upper function layer and the lower function layer, each of the upper spun conductive yarn and the lower spun conductive yarn is of a structure in the shape of a Chinese character gong, the upper spun conductive yarn and the lower spun conductive yarn are in 90-degree warp and weft staggered and aligned arrangement, and staggered points are arranged in the positions corresponding to the open holes on the isolation layer. Each of the upper function layer and the lower function layer of the flexible fabric keyboard provided by the invention only has two points for being in contact with external signal interfaces, so that the points of the flexible fabric keyboard for being in contact with a computer, a mobile phone or other types of hardware are greatly reduced; and portability, foldability and full-fabric property are realized, and a way for developing the computer which can be worn on a human body is opened.

Description

technical field [0001] The invention relates to a computer peripheral device, in particular to a flexible fabric keyboard. Background technique [0002] At present, there are some reports on flexible fabric keyboards for computers at home and abroad, but there is no large-scale production and application so far. Contact point issues with non-flex external signal interfaces. [0003] Fabric keyboards are mostly composed of multi-layer structures, and the operation processes such as alignment, stitching or bonding of each layer are relatively complicated, which limits mass production. At present, there are related technologies to realize the problem of multi-layer alignment combination, such as Chinese patent CN101369185A, which combines two functional layers and the isolation layer therebetween through three-dimensional weaving technology, thereby effectively reducing the 5-layer keyboard to 3 layers. [0004] However, the functional layer (i.e. the conductive fabric layer)...

AI Technical Summary

Problems solved by technology

Because the textile conductive yarn is softer than ordinary metal wires, it is not easy to fix, and it has poor friction resistance and is easy to break. Too many contact points are not suitable for flexible fabric keyboards, and the keyboard and external circuits will be accelerated during long-term washing or folding. Damage to the contact points, so it is not suitable for the development of wearable computer field
