  • Patent number: 11164707
    Abstract: The invention provides a touch device and an input module. The touch device includes a cover plate, a circuit board, a restoration element, a bracket, at least one conductive pad, and a buffer layer. The circuit board is disposed on one side of the cover plate and has a first surface facing the cover plate, a second surface opposite to the first surface, and at least one conductive switch disposed on the second surface. The bracket is disposed on the second surface of the circuit board. The restoration element is disposed on the second surface, and the conductive pad is disposed on the bracket and located between the bracket and the circuit board. The conductive pad and the restoration element are separately disposed, and the conductive pad corresponds to the conductive switch. The buffer layer is disposed between the second surface and the restoration element.

  • Patent number: 11049672
    Abstract: The present invention provides a touch control device, including a cover plate, a circuit board, an elastic sheet body and a bracket. The circuit board is fixedly arranged below the cover plate. The circuit board is provided with a triggering region located on a bottom surface. The elastic sheet body is arranged under the circuit board and corresponds to the triggering region. The bracket is disposed below the circuit board. The bracket is provided with a first side and a second side which are opposite and a middle region located on the second side and further comprises two cantilevers which are located at both sides of the middle region of the second side and extend towards opposite directions. The elastic sheet body is in contact with the middle region. The end of each cantilever is provided with an abutting-joint structure and is in contact with the circuit board by the abutting-joint structure.
