Abstract: A mechanical keyboard is provided, which includes a plurality of mechanical keys, a circuit board, a plurality of first magnetic elements, a lower casing and a plurality of second magnetic elements. The mechanical keyboard has a key region and an edge region surrounding the key region. The mechanical keys are located in the key region. The circuit board is disposed beneath the mechanical keys. The first magnetic elements are disposed beneath the circuit board and distributed in the key region. The lower casing is disposed beneath the mechanical keys, the circuit board and the first magnetic elements. The second magnetic elements are disposed over the lower casing, in which the second magnetic elements respectively correspond to the first magnetic elements and respectively repel the first magnetic elements.

Abstract: A touchpad module for an electronic device is provided. The touchpad module includes a fixing frame, a touch member, a switch member and an adjusting element. The touch member is installed within an opening of the fixing frame. The switch member is installed on the touch member. The switch member includes a first magnetic element. The adjusting element is accommodated within an adjusting hole of the fixing frame. The adjusting element includes a second magnetic element corresponding to the first magnetic element. Moreover, like poles of the first magnetic element and the second magnetic element face each other. Consequently, a travelling distance of the touch member is adjusted according to a repulsive force between the first magnetic element and the second magnetic element.

Abstract: A touch module includes a touchpad assembly and a connection assembly. The connection assembly includes a main body, plural first coupling plates and plural protrusion posts. When the connection assembly is accommodated within a computer casing, the plural first coupling plates are penetrated through plural first openings of the computer casing and the plural protrusion posts are inserted into the corresponding fixing structures. The plural protrusion posts and the corresponding fixing structures are collaboratively formed as a hinge structure. While the touchpad assembly is pressed down, the connection assembly is swung relative to the computer casing by using the plural protrusion posts as the pivotal shafts, so that the touchpad assembly is correspondingly swung. Due to the hinge structure, the touchpad assembly is swung along a fixed direction. Consequently, the touch module is operated stably.

Abstract: A touchpad module includes a bracket member, a touch member, a supporting element and two elastic elements. The touch member is arranged between a first strip part and a second strip part of the bracket member. The supporting element is arranged between the elastic elements and the touch member. Each elastic element includes a swinging part, a fixing part and a shaft part. The fixing parts are installed on the first strip part and the second strip part, respectively. The swinging part and the fixing part are wider than the shaft portion. In response to an external force, the touch member is swung relative to the bracket member by using the shaft parts as fulcrums. While the touch member is swung, the shaft parts are subjected to deformation and the supporting element and the swinging parts are swung relative to the fixing parts.

Abstract: A touchpad module includes a touch member, a base plate, a switch, a supporting structure and a sheet-like elastic element. The base plate includes a triggering part. The switch is disposed on the touch member and aligned with the triggering part. The supporting structure is arranged between the base plate and the touch member. The sheet-like elastic element is located under the touch member and extended along an extension direction. The sheet-like elastic element includes plural vacant spaces. The plural vacant spaces are discretely arranged along the extension direction. The sheet-like elastic element is divided into a swinging structure and plural fixing structures by the plural vacant spaces. In response to an external force, the touch member is swung toward the base plate by using the supporting structure as a fulcrum, and the swinging structure is swung toward the base plate.
