  • Patent number: 11094479
    Abstract: A key structure includes a keycap, a pedestal and an elastic element. The keycap includes a main body and a coupling shaft. The pedestal includes a key slot. The key slot has an upper part and a lower part. The coupling shaft is penetrated through the upper part of the key slot and movable within the key slot upwardly or downwardly. The elastic element is installed in the lower part of the key slot. After an external force applied to the keycap is released, the elastic element is elastically restored, so that the keycap is returned to an original position. At the same time, the buffering elements in the key slot interfere with the coupling shaft. Consequently, an ascending speed of the keycap is reduced, and a click sound generated from the collision between keycap and the pedestal is reduced.

  • Patent number: 11061493
    Abstract: A mouse roller module includes a roller assembly, a sensing unit and a control unit. The roller assembly includes a stator and a rotator. When the roller assembly is in a first usage mode, the rotator is rotated relative to the stator in response to an applied force of a user. A rotating speed of the rotator relative to the stator is sensed by the sensing unit. If the rotating speed of the rotator relative to the stator reaches a threshold value when the roller assembly is in the first usage mode, the roller assembly is switched form the first usage mode to a second usage mode under control of the control unit. While the first usage mode is switched to the second usage mode, the roller assembly is switched to an enabled state, so that the stator drives rotation of the rotator.
