Abstract
A touchpad module includes an elastic bracket, a touch member, a plurality of connecting elements and a pressure sensing unit. The elastic bracket includes a plurality of cantilevers. The plurality of cantilevers have respective free ends and respective fixed ends. The plurality of connecting elements are connected with the respective free ends and the touch member. When the touch member is pressed in response to an external force, the external force is transmitted to at least one free end through at least one connecting element, the at least one free end is rotated relative to the at least one fixed end in a direction away from the touch member, and the pressure sensing unit is subjected to deformation. According to the deformation, the pressure sensing unit senses a magnitude of a pressing force exerted on the touch member and generates a corresponding pressure sensing signal.
