  • Publication number: 20180122596
    Abstract: A keyboard includes a base plate, a pressure sensing layer, plural key structures, a circuit board, a flexible layer and a controlling unit. The pressure sensing layer is disposed on the base plate and located under the circuit board. The flexible layer is disposed on the pressure sensing layer and located under the circuit board. While a key structure is depressed, a part of the key structure is penetrated through the circuit board to press the flexible layer, and a force is transmitted from the flexible layer to the pressure sensing layer. The controlling unit compares the force with a predetermined force value. According to the comparing result, the controlling unit generates a corresponding pressure sensing signal. Consequently, the use of a single key structure can achieve the functions of multiple keys.

  • Patent number: 9941068
    Abstract: A key structure includes a pedestal with a sliding groove, an upper cover, a triggering element, and a spring strip. The spring strip is movable within the sliding groove. The triggering element is arranged between the pedestal and the upper cover, and located beside the spring strip. When a keycap of the key structure is depressed, the triggering element is moved relative to the pedestal to push the spring strip. In response to the elasticity of the pushed spring strip, the spring strip is slid within the sliding groove to collide with the upper cover. Consequently, the key structure generates sound surely.

  • Patent number: 9941071
    Abstract: A key structure includes a circuit board, a housing, a first metallic element, a second metallic element, a keycap and a conductive strip. The conductive strip is disposed within the housing. The first metallic element and the second metallic element are electrically connected with the circuit board. The housing is disposed on the circuit board. The keycap is fixed on the housing. While the keycap is depressed, a first end of the conductive strip is pressed by the triggering part and the conductive strip is swung relative to the housing. Moreover, a second end of the conductive strip collides with the second metallic element. Consequently, the key structure is triggered. When the second end of the conductive strip collides with the second metallic element, a click sound is generated.

  • Publication number: 20170345588
    Abstract: A scissors-type connecting member includes a first frame and a second frame. The first frame includes a rotating shaft. The second frame includes a pivot hole, an entrance and a stopper. After the rotating shaft is introduced into the pivot hole through the entrance, the first frame is pivotally coupled to the second frame. The stopper is located near the entrance or arranged between the entrance and the pivot hole. A position of the rotating shaft is limited between the stopper and the pivotal hole by the stopper. Consequently, the scissors-type connecting member is assembled easily, and the stability of connecting a first frame and a second frame of the scissors-type connecting member is enhanced. Moreover, the present invention also provides a key structure with the scissors-type connecting member.
