Abstract
The present invention provides a key structure and a manufacturing method thereof. The key structure includes a keycap made of a first material and a graphics made of a second material. A part of the graphics is filled in a groove that extends downwards from an upper surface of the keycap, and an other part of the graphics is exposed outside the groove for press, and the graphics is molded by means of a resin dispensing process. In addition, the present invention further provides a keyboard devices that applies the foregoing key structure.
Claims20
A keyboard device, comprising:
- a keyboard base;
- a plurality of key structures, which is provided on the keyboard base, and is used to move up and down relative to the keyboard base, and each of the key structures comprises:
- a keycap, which is made of a first material, and comprises a groove that extends downwards from an upper surface of the keycap;
- and
- a graphics, which is made of a second material, and a part of the graphics is filled in the groove, and an other part of the graphics is exposed outside the groove;
- and
- a plurality of key switches, which respectively corresponds to the plurality of key structures, and any one of the plurality of key switches generates and outputs a corresponding key signal in responding to a press on the graphics of the corresponding key structure.
A key structure, comprising:
- a keycap, which is made of a first material, and comprises a groove that extends downwards from an upper surface of the keycap;
- and
- a graphics, which is made of a second material, which is different from the first material, and a part of the graphics is filled in the groove, and an other part of the graphics is exposed outside the groove for press.
A method for manufacturing a key structure, comprising:
- forming a keycap having a groove by means of an injection process, wherein the groove extends downwards from an upper surface of the keycap;
- and
- forming a graphics at the groove by means of a resin dispensing process, and at least a part of the graphics is exposed outside the groove.
