Keyboard device

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 switch circuit board located under the key structure, and comprising a key switch corresponding to the key structure, wherein when the key switch of the switch circuit board is triggered by the key structure, a key signal is generated;
• a base plate located under the switch circuit board, and supporting the key structure, wherein the base plate comprises a connecting structure, and the connecting structure is connected with the hook part, so that the stabilizer bar is connected with the base plate;
• and a buffering element coupled with the connecting structure, wherein the hook part and the connecting structure are separated from each other through the buffering element;
• wherein the buffering element comprises:
• an upper buffering part contacted with a top surface of the connecting structure, wherein when the keycap is depressed, the upper buffering part is contacted with the keycap to absorb an impact from the keycap;
• a lower buffering part contacted with a bottom surface of the connecting structure and arranged between the connecting structure and the hook part, wherein the hook part and the connecting structure are separated from each other through the lower buffering part;
• and an extension part arranged between the upper buffering part and the lower buffering part and connected with the upper buffering part and the lower buffering part.
