Key structure and manufacturing method thereof, and keyboard device using key structure

Abstract

The invention provides a key structure and a manufacturing method thereof. The key structure comprises a key cap made from a first material and a graphic piece made from a second material, wherein onepart of the graphic piece is filled into a groove formed by downwards extending the upper surface of the key cap, the other part of the graphic piece is exposed out of the groove for being pressed, and the graphic piece is molded by a gluing technology. In addition, the invention also provides a keyboard device using the key structure. The key structure provided by the invention has the three-dimensional graphic piece, so that the user capacity for recognizing the key structure via operation hand feeling can be enhanced, and thus the key structure has extremely high industrial utilization value.

Description

technical field [0001] The invention relates to the field of input devices, in particular to a key structure, a manufacturing method thereof, and a keyboard device using the key structure. Background technique [0002] With the continuous advancement of science and technology in modern society, electronic products are widely used in daily life, and the button structure used in electronic products needs to be matched with various electronic products, and it is also constantly moving towards reducing manufacturing costs, improving processes and improving Yield and other aspects of efforts to enhance product competitiveness. In addition, common computer peripheral input devices include a mouse device, a keyboard device, and a trackball device. The keyboard device including a key structure has attracted considerable attention because it allows the user to directly input characters and symbols into the computer. [0003] see figure 1 , which is a structural top view of an exist...

AI Technical Summary

Problems solved by technology

However, the disadvantage of the existing key structure 12 is that the upper surface of the key cap 121 is too smooth, and its text or graphics 1211 cannot provide a three-dimensional effect, so the user cannot recognize the key structure 12 by the touch during operation.

[0005] Furthermore, when the existing key structure 12 is applied to a light-emitting keyboard, the text or graphics 1211 on the upper surface of the keycap 121 must be specially treated for light transmission, so that the light-emitting elements (not shown in the figure) arranged in the keyboard device 1 can be light-transmitting. As shown), the light beams provided are output outward, and in view of the limitations of the existing keycap 121 manufacturing process, the colors of the light beams output from the same character or the same shape are all the same, and it is not easy to present in colorful styles to assist visual recognition ,E.g figure 2 The four blocks of the shown graphic 1211 (windows logo key) cannot individually present beams of different colors
