KEY MODULE AND KEYBOARD HAVING THE SAME

摘要

A key module and a keyboard having the key module are provided. The key module includes a base, a scissor-type unit and a keycap. The scissor-type unit has a first frame and a second frame. The first frame has a connection shaft rotatably pivotally connected to a shaft hole of the second frame. The shaft hole has a travel distance therein for the shaft to move within the shaft hole along a predetermined direction. The first and second frames respectively have a first side pivotally connected to a pivot connection unit of the key cap, and a second side slidably connected to a restricting unit of the base. Through the above-mentioned design, the first frame can rotate with respect to the second frame, so that the keycap can move up and down with respect to the base.

主权项

1. A key module comprising:
a base having a restricting unit; a scissor-type unit disposed on and connected to the base, and having a first frame and a second frame, wherein the first frame has a connection shaft, the second frame has a shaft hole, the first frame is rotatably connected to the second frame through an accommodation of the connection shaft in the shaft hole, and the shaft hole has a travel distance therein provided for the connection shaft to move within the shaft hole along a predetermined direction; and a keycap disposed on and connected to the scissor-type unit, and having a pivot connection unit, wherein a first side and a second side of the first frame are respectively rotatably connected to the pivot connection unit and slidably disposed at the restricting unit, a first side and a second side of the second frame are respectively rotatably connected to the pivot connection unit and slidably disposed at the restricting unit; wherein through the respective pivotal connections of the first side of the first frame and the first side of the second frame to the pivot connection unit, the respective slidable arrangement of the second side of the first frame and the second side of the first frame at the restricting unit, and the movement of the connection shaft within the shaft hole, the first frame rotates with respect to the second frame and the keycap moves up and down with respect to the base.
