1. A touchpad module for a computing device, the touchpad module being installed within a fixing frame of the computing device, the touchpad module comprising:
a base plate comprises an elastic arm;
a touch member located over the base plate;
a conductive supporting structure arranged between the elastic arm and the touch member, wherein the elastic arm is aligned with the conductive supporting structure in a thickness direction of the touchpad module;
a first adhesive layer arranged between the conductive supporting structure and the touch member;
a second adhesive layer arranged between the conductive supporting structure and the elastic arm; and
a conducting element connected between the base plate and the fixing frame of the computing device,
wherein an electrostatic discharge path is defined by the touch member, the conductive supporting structure, the base plate, the conducting element and the fixing frame of the computing device collaboratively, and static electricity generated on the touch member is guided out of the touchpad module through the electrostatic discharge path;
wherein the touchpad module further comprises a pressure sensor, and the pressure sensor is installed on the elastic arm, wherein when an external pressing force is exerted on the touch member, the touch member is moved in a direction toward the base plate, wherein while the touch member is moved in the direction toward the base plate, the conductive supporting structure is correspondingly moved with the touch member to push the base plate, so that the base plate is subjected to deformation and the base plate has a deformation amount, wherein when the pressing force exerted on the touch member is sensed by the pressure sensor according to the deformation amount, the pressure sensor generates a pressure sensing signal;
wherein while the touch member is moved in the direction toward the base plate, the conductive supporting structure is correspondingly moved with the touch member to push the elastic arm of the base plate, so that the elastic arm is subjected to the deformation and the elastic arm has the deformation amount, wherein when the pressing force exerted on the touch member is sensed by the pressure sensor according to the deformation amount, the pressure sensor generates the pressure sensing signal.
