The keyboard device includes a substrate, a key, a first elastic member, and a second elastic member. The substrate includes a top surface having an assembly area. The assembly area has a pivoting base including a standing portion and an extension portion extending from the standing portion. The key is liftably disposed over the assembly area. A pivoting hook is extending from the bottom of the key toward the assembly area, and one end of the pivoting hook includes a pivoting portion. The first elastic member and the second elastic member are disposed on the assembly area and elastically abutted against the bottom of the key, so that the pivoting portion is abutted against and pivoted to the extension portion, and a liftable distance is maintained between the extension portion and the bottom of the key.

The present invention discloses a film structure for a keycap, including a molding film presenting a shape conforming with the outline of the upper surface outline of the keycap; and a polyurethane (PU) layer disposing on the molding film and engraved a symbol thereon, wherein the symbol indicates a specific keycap. In the present invention, the problems with the symbols of the keycaps becoming dislocated, yellowed and deformed when the keycaps are manufactured with currently available techniques can be overcome, and users can clearly see the symbols on a backlit keyboard.

The present invention discloses a keycap for keys of a keyboard device, wherein the keys are configured on the keyboard, and the keycap is configured on a key body. The keycap includes: a top fabric layer, a keycap body including an upper surface outline, and a molding film. The top fabric layer is used for engraving to have a symbol thereon to transmit light therethrough, wherein each symbol indicates a specific keycap. The molding film is disposed between the top fabric layer and the keycap body to render the top fabric layer in a specific shape matching with the upper surface outline. In the present invention, the problems with the symbols of the keycaps becoming dislocated, yellowed and deformed when the keycaps are manufactured with currently available techniques can be overcome, and users can clearly see the symbols on a backlit keyboard.

Example implementations relate to magnetic keyboard domes. In an example, a keyboard dome includes a dome with an exterior surface, and a metal magnetic pad on the exterior surface of the dome to guide the dome to a keyboard membrane.

A key device includes a substrate having an assembling area, a keycap, and a restoring member. A pivot coupling member and an elastic arm are provided in the assembling area. The pivot coupling member has a pivot axis, and the elastic arm is extending in a direction parallel to the pivot axis. The elastic arm includes a limiting member protruding out of the substrate. The keycap is disposed above the assembling area. A connection arm is extending from the keycap and includes a pivot portion pivoted with the pivot coupling member, so that the keycap is swingable relative to the substrate. The keycap further includes a limiting groove for detachably fitted with the limiting member. The restoring member is disposed between the substrate and the keycap. The restoring member is adapted to provide a restoring force for swinging the keycap relative to the substrate.

A keyboard structure and assembling method thereof are provided. The keyboard structure includes a baseplate, a keycap and a frame having a hook body. The keycap can be inserted into the frame and restricted by the hook body, so that the range of movement of the keycap is restricted. The keycap cannot be separated from the frame so that the coupling of the frame and the baseplate is not interfered by the keycap. Thus, the present invention can effectively simplify the assembling process of the keyboard.

A cap structure is combined with a lifting mechanism to be movable between a pressed position and a non-pressed position. The cap structure includes a first circuit, a second circuit, a flexible circuit board and a cap having a top surface, a bottom surface and an engaging structure. The engaging structure protrudes from the bottom surface for engaging with the lifting mechanism. The first circuit is laid out on the top surface for connecting to a sensing device or a display device attached on the top surface. The second circuit is laid out on the bottom surface and avoids the engaging structure. The second circuit passes through the cap to be connected to the first circuit. The flexible circuit board is connected to the second circuit for performing signal transmission of the sensing device or the display device via the first and second circuits.
