Abstract: A keyswitch includes a bottom board, a cap structure, a lifting mechanism, and an elastic member. The lifting mechanism is detachably connected to the cap structure and the bottom board to make the cap structure movable upward and downward relative to the bottom board. The elastic member is connected to the cap structure so as to be detached from the lifting mechanism together with the cap structure when the cap structure is separate from the lifting mechanism.

Abstract: A keyswitch structure includes a base plate, a keycap, and a keycap support mechanism that supports the keycap above the base plate in a vertical direction. The keycap and the keycap support mechanism extend lengthwise in a lengthwise direction. The keycap support mechanism includes an outer support and an inner support pivotally connected to each other. The outer support surrounds the inner support. The inner support includes a support body and a reinforcement part. The reinforcement part is embedded in the support body. The reinforcement part is greater in elastic modulus than the support body. The inner support defines a side connection section on both sides of the inner support in the lengthwise direction. Each side connection section includes at least one base plate connecting portion and at least one keycap connecting portion. The reinforcement part extends into the two side connection sections.

Abstract: A multi-size keyswitch structure includes a base plate, a multi-size keycap, and a keycap support mechanism that supports the multi-size keycap above the base plate in a vertical direction. The multi-size keycap and the keycap support mechanism extend lengthwise in a lengthwise direction. The keycap support mechanism includes an outer support and an inner support pivotally connected to each other. The outer support surrounds the inner support. The inner support includes a support body and a reinforcement part. The reinforcement part is embedded in the support body. The reinforcement part is greater in elastic modulus than the support body.

Abstract: 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.
