Problems solved by technology

However, the pressing feeling provided by the pressing spacer is not only still not comparable to that of the traditional keyboard, but also must face the problem of alignment accuracy when the pressing spacer is arranged on the cover layer, so its manufacturing cost will also be affected by the additional pressing spacer. piece by piece
[0004] In addition, in the manufacturing process of the existing pressing pads, the glue needs to be injected into the mold to form the shape of the corresponding button. After the glue is hardened and formed, it is then adhered to the sheet body. The overall process is time-consuming and complicated.

Abstract

The invention discloses an overlay structure which comprises a bottom coating layer, a top coating layer and a thermoplastic material layer. The thermoplastic material layer is overlapped between the bottom coating layer and the top coating layer. The thermoplastic material layer comprises first thermoplastic material layer portions and second thermoplastic material layer portions which are connected with one another. The first thermoplastic material layer portions have first thicknesses. The second thermoplastic material layer portions have second thicknesses. The first thicknesses are larger than the thickness of the top coating layer. Each first thickness is 4-7 times each second thickness. The invention further discloses an input device with the overlay structure and a method for manufacturing the overlay structure.

Description

technical field [0001] The invention relates to a covering structure, an input device using the covering structure and a manufacturing method of the covering structure. Background technique [0002] Although tablet PCs have become more and more popular in recent years, the keyboard (or mouse) is still an important input device for inputting characters, symbols or numbers in terms of current usage habits of personal computers. Therefore, at present, some operators have introduced a thin touch keyboard specially used for tablet computers, which can also be used as a protective cover for tablet computers. In order to achieve a thinner appearance, the touch keyboard uses a force sensitive resistor (Force Sensitive Resistor, FSR) as a component for sensing input signals, and covers the surface with a covering layer for the user's finger to touch. [0003] However, the touch keyboard cannot provide the user with a pressing feeling similar to that provided by a traditional keyboar...
