  • Patent number: 10629394
    Abstract: A keyswitch assembly is provided. The keyswitch assembly includes a keyswitch module having a key cap, a light guiding member disposed above an outer surface of the key cap and a light source module disposed corresponding to the light guiding member. The light guiding member has a first surface adjacent to the key cap and a second surface facing away from the key cap and opposite the first surface. The light source module provides a light beam incident to the light guiding member. In the invention, the illumination effect of the keyswitch assembly is improved and the power consumption of the keyswitch assembly is reduced by way of disposing the light guiding member of the keyswitch assembly above the outer surface of the key cap.

  • Patent number: 10184609
    Abstract: Disclosed is a key supporting structure. The key supporting structure includes a scissor-type component having a first supporting element and a second supporting element that are pivotally connected to each other. The first supporting element has a first frame, and two end of the first frame have at least one first pivot and at least one second pivot respectively. The second supporting element has a second frame, and two end of the second frame have at least one third pivot and at least one fourth pivot respectively. The first frame and the second frame are made from a powder sintered material. The first pivot, the second pivot, the third pivot, and the fourth pivot are formed on the first frame and the second frame by plastic injection molding method.

  • Patent number: 6982870
    Abstract: A portable storage device assembled inside a housing of a computer. The computer includes a storage device fixture including at least one fixing hole. The portable storage device includes a storage module, a bracket for carrying the storage module, and an elastic structure connected to the bracket including at least one stop component on the elastic structure for wedging in the fixing hole on the storage device fixture so as to fix the connection between the portable storage device and the computer. When the elastic structure is pressed down, the stop component of the elastic structure does not wedge in the fixing hole on the storage device fixture, and when the elastic structure is not pressed down and is restored to the original location, the stop component of the elastic structure wedges in the fixing hole on the storage device fixture.
