Claim 0:
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;
a touch member located over the base plate, wherein the touch member comprises a touch plate and a touch sensitive circuit board;
at least one pressure sensing module arranged between the base plate and the touch member, wherein each of the at least one pressure sensing module comprises a pressure sensor and a miniature supporting plate, wherein the pressure sensor is installed on the miniature supporting plate, wherein while the touch member is pressed in response to an external pressing force, the pressing force exerted on the touch member is sensed by the at least one pressure sensing module, and the at least one pressure sensing module generates a pressure sensing signal; and
at least one cantilever structure, wherein the at least one cantilever structure is arranged between the touch member and the base plate, and the at least one pressure sensing module is installed on the at least one cantilever structure, wherein while the touch member is pressed in response to the pressing force, the at least one cantilever structure is compressed by the touch member, so that the at least one cantilever structure is subjected to deformation and the at least one cantilever structure has a deformation amount, wherein when the pressing force exerted on the touch member is sensed by the pressure sensing module according to the deformation amount, the at least one pressure sensor generates the pressure sensing signal.
