Abstract: A key structure is provided. The key structure includes a base plate, a keycap, a positioning element and a rod. The base plate has a through hole. The positioning element is engaged with the through hole. A projection area of the positioning element on the base plate along a lifting direction of the keycap is larger than an area of the through hole.

Abstract: The disclosure provides a keyboard including a bottom plate, a key unit and a shielding layer. The bottom plate includes a through hole. The key unit is disposed on the bottom plate. The shielding layer covering a portion of the bottom plate includes a main part and an extension part extending from the main part toward the through hole. The shielding layer is provided with a black surface, and an orthographic projection of the key unit on the shielding layer overlaps the black surface.

Abstract: The disclosure provides a keyboard includes a bottom plate, a key unit and a shielding layer. The bottom plate includes a body part and a through hole. The key unit is disposed on the body part. The shielding layer covers a portion of the bottom plate and comprising a main part disposed on the body part and an extension part extending from the main part toward the through hole, wherein the extension part has a hole with a size larger than or substantially equal to a size of the through hole.

Abstract: A key structure includes a base plate, a key cap, a supporting member, a link member, and a buffer member. The base plate includes a body portion and a protrusion portion protruding upward from the body portion. The body portion has an accommodating hole, the accommodating hole corresponds to the protrusion portion, and the protrusion portion has an opening. The key cap is disposed above the base plate. The supporting member is disposed between the key cap and the base plate. The link member includes a main body portion and an end portion. The main body portion is pivotally connected to the key cap, and the end portion is disposed at the opening of the protrusion portion. The buffer member is located below the end portion, and the end portion leans against the buffer member.

Abstract: A key structure includes a keycap, a connection assembly, engaging members, and a base plate. The connection assembly disposed between the base plate and the keycap is movably connected to the keycap and the engaging members, so that the keycap and the connection assembly engaged with the engaging members are positioned on the base plate. The base plate includes engaging protrusions protruding from an upper surface, so that the engaging members are bonded to the base plate through the engaging protrusions. Each engaging protrusion is located between two openings of the base plate, connects the two openings, or is disposed corresponding to the openings. Each engaging member covers one or more engaging protrusions through injection molding, and is fixed to the base plate. The engaging members are respectively disposed on the openings, fill the openings, or completely cover the engaging protrusions.
