Abstract
A keyboard device includes a key structure, a base plate and a switch circuit board. The switch circuit board includes a soft covering element. The key structure includes a keycap and a stabilizer bar. The stabilizer bar is connected with the keycap and the soft covering element. The soft covering element is disposed on the switch circuit board. An accommodation space is formed between the soft covering element and the switch circuit board. The stabilizer bar is inserted into the accommodation space and connected with the switch circuit board. The stabilizer bar and the base plate are made of metallic material. Since the stabilizer bar and the base plate are separated by the switch circuit board, the keyboard device is capable of reducing noise.
Claims11
A keyboard device, comprising:
- a key structure comprising a keycap and a stabilizer bar, wherein the keycap is exposed outside the keyboard device, the stabilizer bar is connected with the keycap, and comprises a linking bar part and a hook part, wherein the linking bar part is connected with the keycap, and the hook part is located at an end of the linking bar part;
- a base plate disposed under the key structure, and connected with the key structure;
- and
- a switch circuit board arranged between the key structure and the base plate, wherein when the switch circuit board is triggered, a key signal is generated, wherein the switch circuit board comprises:
- a key switch aligned with the key structure, wherein when the key switch is triggered by the key structure, the key switch generates the key signal;
- a soft covering element disposed on the switch circuit board, wherein an accommodation spaces is defined by the soft covering element and the switch circuit board collaboratively, and the hook part is inserted into the accommodation space, so that the hook part is permitted to be moved within the accommodation space;
- an upper wiring plate comprising an upper circuit pattern, wherein the upper circuit pattern is formed on a bottom surtface of the upper wiring plate;
- a lower wiring plate disposed under the upper wiring plate, and comprising a lower circuit pattern, wherein the lower circuit pattern is formed on a top surface of the lower wiring plate;
- and
- a separation layer arranged between the upper wiring plate and the lower wiring plate, and comprising a perforation, wherein the upper circuit pattern and the lower circuit pattern are separated from each other through the separation layer, and the key switch is defined by the upper circuit pattern, the perforation and the lower circuit pattern collaboratively,
- wherein the lower wiring plate has an extension region, and the extension region is protruded out of the upper wiring plate and the separation layer, wherein the soft covering element is adhered on a top surface of the extension region, an end of the accommodation space is closed, and the hook part is inserted into the accommodation space.
