A mouse device includes a mouse shell, a switch module, and a key module. The mouse shell has an upper shell and a lower shell, and the upper shell and the lower shell are joined together to form a chamber. The switch module is disposed within the chamber and is suspended from an inner side of the upper shell. The key module is disposed on an outer side of the upper shell. The key module is vertically movable and has a trigger. The trigger enters the chamber through the upper shell to activate the switch module when the key module is clicked.

A key structure including a base, a pivoting structure and a cap is provided. The base includes a plate, a first limiting unit and a second limiting unit. The pivoting structure includes a first pivoting part and a second pivoting part, the first pivoting part has a connecting shaft, and the second pivoting part has a shaft hole in which the connecting shaft is received and slidable, The cap has a first pivoting unit and a second pivoting unit, one side of the first pivoting part and one side of the second pivoting part are pivotally connected to the first pivoting unit and the second pivoting unit respectively, and the other side of the first pivoting part and the other side of the second pivoting part are slidably disposed in the first limiting unit and the second limiting unit respectively.

A key switch includes a base, a key cap, a link bar and a buffer member. A first hook of a first extending arm of the base and a second hook of a second extending arm of the base extend toward opposite directions respectively. An upper linking end of the link bar is movably connected to the key cap. The buffer member is made of material softer than material of the base. When the first hook and the second hook engage with a first engaging portion and a second engaging portion of the buffer member respectively, a recess structure of the buffer member is adjacent to the base to form a restraining structure. A lower linking end of the link bar is movably disposed through the restraining structure. Therefore, the key switch of the present invention has noise reduction capability.

An article comprising a bulk metallic glass skin having one or more functional features integrated therein is described and a method of forming the same is described. The one or more functional features exhibit a variation in stiffness between the one or more functional features and the bulk metallic glass skin that is defined by an applied force over an achieved deformation. The stiffness of each of the one or more functional features is at least 1000 times less than an average stiffness of the bulk metallic glass skin.

The present invention relates to a keyboard, including a first baseboard, a second baseboard, a deformation element, a key cap, and a connecting element. The deformation element is disposed between the first baseboard and the second baseboard and is capable of deforming according to a received voltage signal. The deformation element drags the second baseboard to move in a first direction when the deformation element receives the voltage signal and therefore deforms to be in an extended state, so that the key cap is at a first height. The deformation element pushes the second baseboard to move in a second direction when the deformation element does not receive the voltage signal and therefore deforms to be in a bent state, so that the key cap is at a relatively shorter second height.

A to-be-depressed member includes an elastic dome. A sectional shape of the dome orthogonal to an axis line (X2) of the dome is line-symmetric about a symmetry axis (Ax). The dome has a three-dimensional shape that is symmetric with respect to a virtual plane (Sx) containing the symmetry axis and the axis line. During a swinging movement responsive to a depressing operation, an opposed surface of an opposed member relatively approaches and contacts a distal end of the dome to deform the dome so as to generate a reactive force. As for an angle defined between the axis line of the dome and a normal line (X1) of the opposed surface, the angle (0) in an initial state falls in a range from a first angle variation amount from the initial state to a first-contact state to a second angle variation amount from the initial state to a depression-completed state.

The present invention provides a key structure, including: a key cap, a support board, an elastic element, and a support element. The elastic element includes an elastomer and an elastic piece. The elastomer has a first surface and a second surface, where the first surface includes a first protrusion portion and a second protrusion portion. The support element is connected the key cap and the support board and surrounds the elastic element. When the key cap descends, the first protrusion portion is pressed by the key cap and generates a deformation, so as to form a first pressing stroke, and subsequently, the key cap presses the second protrusion portion to enable the elastic piece to generate a deformation, so as to form a second pressing stroke.

An electric switch includes a base which receives a plurality of fixed electrical contacts and a movable electrical contact. The switch also includes an actuating body made of elastic material. The switch also includes a central, top, pushbutton. The body includes a lateral part, surrounding a top force-receiving portion. The pushbutton includes a lateral actuating surface for acting on this top lateral part of the body. When operated, successively, the central actuating surface of the pushbutton acts on the top force-receiving portion and elastically deforms a wall part of the body, and then the lateral actuating surface of the pushbutton acts on the top lateral part.

A key mechanism including one or more butterfly hinges. Each butterfly hinge may include a double wing design operative to move between a depressed position and non-depressed position. Hinged coupling mechanisms couple respective arms of the wings together. Additionally or alternatively, a key mechanism can include one or more half-butterfly hinges. Each half-butterfly hinge includes a double wing design operative to move between a depressed position and non-depressed position. A hinged coupling mechanism couples one set of corresponding arms of the wings together, while the other set of corresponding arms are not coupled together.

A keyboard device for a portable computer is disclosed. The portable computer includes a main body chassis and a display chassis. The main body chassis contains the keyboard device having multiple keycaps elastically supported to be moved up and down. Coupled to the main body chassis via a hinge, the display chassis contains a display. The main body chassis also includes a key depressing mechanism having a rotating shaft member provided along each of the keycaps and a pressing piece projecting from the outer circumferential surface of the rotating shaft member to the side of the keycap to allow a receiving part provided in the keycap to be depressed downward. The rotating shaft member rotates about the axis to cause the pressing piece to push down the receiving part and, in turn, pushing down and keeping the keycap in a depressed position.
