27 KEYBOARD AND NOTEBOOK COMPUTER WITH SAME US15339243 2016-10-31 US20170371422A1 2017-12-28 Che-Wei Yang; Yi-Chen Wang; Wei-Yung Huang
A keyboard and a notebook computer with the keyboard are provided. The keyboard is installed on the notebook computer. The keyboard includes a membrane circuit board, a key frame, a key, a linking rod and a fixing plate. The linking rod is connected with the key frame. The fixing plate is disposed under the key frame. While the linking rod is rotated relative to the key frame to push the key frame, a position-limiting structure of the key frame is moved along a guiding structure of the fixing plate. Consequently, the key frame is limited to be moved in a first axial direction. Moreover, when the key frame is moved to a locked position at the same level with a keycap of the key, the keycap cannot be pressed down.

A keyboard has an upper case, a lower case, and a stacked functional structure formed by stacking and fastening together a membrane switch sheet, a rubber sheet and a housing supporting keys in that order on a curved plate and a flat plate. When assembling the stacked functional structure, the membrane switch sheet and the rubber sheet are placed in that order on the curved plate and the flat plate supported in place on the bottom wall of the lower case and support ribs formed on the inner surface of the bottom wall of the lower case, connecting hooks formed integrally with the housing are inserted through aligned slots formed in the rubber sheet, the membrane switch sheet, the curved plate and the flat plate so that the connecting hooks engage with the lower surfaces of the curved plate and the flat plate with the membrane switch sheet and the rubber sheet are sandwiched firmly between the housing, and the curved plate and the flat plate. The stacked functional structure is sandwiched between the upper and the lower case, and then the upper and the lower case are fastened together to complete the keyboard.

A push button kind of switch has an elongate stem (7) mounting a cap member (14) and engaged at its lower end in a member (4) retained in a housing (2) and biassed upwardly by a spring (5). A switch member (1) comprising a diaphragm and contacts is operated upon downward movement of the elongate stem (7) by a cushion member (6).

Tactile indication of switch operation is given by a profiled portion (15) of the stem (7) co-operating with spring biassed balls (13) in bores (11) in a housing (10). The springs (12), balls (13) and profiled portion (15) provide a high initial resistance to axial movement of the stem (7) followed by rapid collapse and virtually no resistance.
