Abstract
A key device for a keyboard includes a circuit board, a keycap located over the circuit board, a supporting plate disposed under the circuit board, a first stabilizing member, a second stabilizing member and two supporting members. The supporting plate includes two first mounting seats cooperatively defining a rotating axis extending in a first direction. Each of the first stabilizing member and the second stabilizing member is made of a plastic material, slidably engages the keycap, and is rotatably mounted to the first mounting seats. When the keycap is pressed toward the supporting plate, the first stabilizing member and the second stabilizing member rotate relative to the supporting plate about the rotating axis.
Claims8
A key device for a keyboard, said key device comprising:
- a circuit board;
- a keycap located over said circuit board and having
- an inner surface that faces said circuit board,
- an outer surface that faces away from said circuit board,
- two first engaging members that are disposed on said inner surface, and
- two second engaging members that are disposed on said inner surface;
- a supporting plate disposed under said circuit board and including
- a board body and two first mounting seats that are spaced apart from each other in a first direction, that are disposed on a surface of said board body facing said circuit board, and that cooperatively define a rotating axis extending in the first direction;
- a first stabilizing member made of a plastic material and including
- a first stabilizing rod that extends in the first direction and that slidably engages said first engaging members, and
- two first extending rods that respectively extend from two opposite ends of said first stabilizing rod, each of said first extending rods having a first mounting section that is rotatably mounted to a respective one of said first mounting seats such that said first stabilizing member is rotatable relative to said supporting plate about the rotating axis;
- a second stabilizing member made of a plastic material and including
- a second stabilizing rod that extends in the first direction and that slidably engages said second engaging members, and
- two second extending rods that respectively extend from two opposite ends of said second stabilizing rod, each of said second extending rods having a second mounting section that is rotatably mounted to a respective one of said first mounting seats such that said second stabilizing member is rotatable relative to said supporting plate about the rotating axis;
- and
- two supporting members each of which interconnecting said supporting plate and said keycap, and located between said first mounting seats of said supporting plate;
- wherein, when said keycap is pressed toward said supporting plate, said first stabilizing rod and said second stabilizing rod slide relative to said first engaging members and said second engaging members in a second direction perpendicular to the first direction, and said first stabilizing member and said second stabilizing member simultaneously rotate about the rotating axis.
