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.

Key structure

A button assembly includes a bottom plate, a cap, an elastic member, a link member, and an interference member. The cap is disposed on the bottom plate, and the cap has a button surface and an inner surface relative to each other. The elastic member is disposed under the cap. The link member has two parallel portions parallel to each other and a horizontal portion connected with the two parallel portions, wherein the two parallel portions are disposed to the bottom plate and the horizontal portion is disposed to the inner surface. The interference member is disposed between the inner surface and the link member.

Button assembly

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.

Keyboard

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.

Positioning member and keyboard containing the same

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.

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.

The disclosure provides a key structure including a base plate, a keycap, and a compressible supporting mechanism. The keycap is disposed above the base plate. The keycap has a top surface and a bottom surface opposite to each other and includes a bonding member protruding from the base surface. The bonding member has a groove and a guiding surface. The compressible supporting mechanism is disposed between the base plate and the keycap. The compressible supporting mechanism is assembled into the groove as being guided by the guiding surface. In the key structure provided by the disclosure, since the compressible supporting mechanism is guided by the guiding surface, interference generated when the compressible supporting mechanism and the keycap are assembled may be reduced, so that the bonding member is prevented from being damaged or collapsing when being pressed in a process of assembling.

The disclosure provides a positioning member includes a bottom plate and a shielding layer. The bottom plate includes a body part and a protruding part. The body part has a connection part. The protruding part has a through hole. The body part is upwardly connected to the protruding part through the connection part, such that the body part, the connection part and the protruding part jointly enclose an accommodating space below the through hole. An joint member having a stud and a head connected to the stud, wherein the stud passes through the through hole to be fixed in the accommodating space via the head. The shielding layer is disposed on the body part, partly extending to the through hole of the protruding part to shield the protruding part exposed by the joint member. A keyboard is further provided.

A key structure and a keyboard using the same are disclosed. The key structure includes a bottom plate, a keycap, a lifting mechanism, a backlight module, a fixer and a fixing portion. The lifting mechanism pivotally connects the bottom plate and the keycap. The backlight module is disposed on the bottom plate and is provided with a through hole, a first surface and a second surface opposite to the first surface. The through hole is extended to the second surface from the first surface. The fixer presses the first surface. The fixing portion presses the fixer on the bottom plate.

Key structure and keyboard using the same

The disclosure provides a key module including a bottom plate, a keycap and a scissor structure. The keycap is located above the bottom plate. The key cap includes a pivoting member protruding from the bottom surface and a sliding member. The pivoting member has a pivot hole and a hollowed-out area communicating with the pivot hole. The scissor structure is disposed between the bottom plate and the keycap, and includes a first leg and a second leg pivotally connected to each other, the first side of the first leg and the second side of the second leg are connected to the bottom plate, the third side of the first leg is rotatably connected to the pivoting member of the keycap, and the fourth side of the second leg is slidably connected to the sliding member of the keycap.

Key module

Provided is a key structure including a base plate having at least one connecting seat and at least one notch adjacent to a lower portion of the connecting seat; a keycap disposed above the base plate in a liftable manner; a thin film circuit assembly disposed on the base plate and located between the base plate and the keycap; and a supporting rod connected to the keycap and the base plate and located between the thin film circuit assembly and the keycap. An accommodating space formed by the notch extends from and communicates with a through hole of the connecting seat. The connecting seat protrudes out from an opening of the thin film circuit assembly. A vertical projection region of the notch on the base plate is located within a vertical projection region of the opening on the base plate. The invention also provides a keyboard module.
