Patent ID: 8726408

Claim:
An electronic device with encryption function, comprising: a housing having a groove; a function module disposed in said housing; and a mechanical lock disposed in said groove, a portion of said mechanical lock being exposed from said groove, said mechanical lock including: a lock shell; a plurality of lock wheels rotatably disposed in said lock shell, a portion of each of said lock wheels being accessible externally of said lock shell; a lock axle disposed in said lock shell and movably extended through said lock wheels; a first conductive component; and a second conductive component; said lock axle having a first connecting end, said first conductive component being disposed in said lock shell and being disposed at said first connecting end of said lock axle, and being coupled to one of a power source and said function module, said second conductive component being disposed in said lock shell and being disposed at one end of said lock shell proximate to said first connecting end, and being coupled to the other one of the power source and said function module; wherein rotation of said lock wheels to an unlocking state permits movement of said lock axle between a first position, where said first conductive component and said second conductive component are electrically connected, and a second position, where said first conductive component and said second conductive component are electrically disconnected, and when said first conductive component and said second conductive component are electrically connected, said function module is able to electrically connect to the power source so as to obtain electrical power therefrom, and wherein said lock axle further has a second connecting end disposed opposite to said first connecting end, said mechanical lock further including a resilient component disposed in said lock shell, said resilient component being connected between said second connecting end and one end of said lock shell proximate to said second connecting end, and rotation of said lock wheels to the unlocking state enabling said resilient component to release a restoring force for moving said lock axle to make electrical connection between said first conductive component and said second conductive component.
