Abstract
A key structure includes a base and a linkage mechanism. The linkage mechanism includes a plurality of linking members movably connected to each other. The plurality of linking members includes at least two linking members rotatably positioned on the base, respectively. When a pressing force is applied to the linkage mechanism, the plurality of linking members move associated with each other to restrict a rotation range of the plurality of linking members with respect to the base.
Claims14
A key structure, comprising:
- a base;
- and
- a linkage mechanism comprising a first linking member and a second linking member movably connected to each other to form a coupling axis, the first linking member and the second linking member rotatably positioned on the base, respectively,
- wherein the first linking member has a first pivoting portion;
- the first linking member couples with the base through the first pivoting portion to form a first rotation axis;
- the second linking member has a second pivoting portion;
- the second linking member couples with the base through the second pivoting portion to form a second rotation axis,
- wherein when a pressing force is applied to the linkage mechanism, the first linking member rotates about the first rotation axis along a first direction to drive the coupling axis to move relative to the base, so the second linking member is driven to rotate about the second rotation axis along a second direction, the first direction and the second direction are a same direction or different directions, and a rotation range of the first linking member and the second linking member with respect to the base is restricted due to interference between moving paths of the first linking member and the second linking member.
