NFC driven disc lock
Described herein is a Near Field Communication disc lock. The disc lock has a near field communication antenna which receives the near field signal to lock or unlock the disc lock. The antenna passes the signal via wires to a near field circuit board which controls the lock motor which turns a lock cam to pressure or release a lock ball. The lock ball triggers the lock ball lever to lock or unlock the lock ring. In this manner, there is now an NFC lock which cannot be cut with bolt cutters.
1. A disc lock comprising an antenna chamber, a lock ring, a top housing section, a bottom housing section assembled with the top housing section to form a housing having an annular shaped lock chamber and a housing notch, wherein the lock chamber houses a lock mechanism and the antenna chamber houses an antenna system, wherein the lock mechanism comprises a lock ball cam, a lock ball, and a lock ball lever, wherein the lock ball cam is configured to put pressure on the lock ball, which pushes the ball lever into a lock notch in the lock ring, thereby keeping the lock ring in a position in which the housing notch is closed by the lock ring and removes the pressure from the lock ball, which allows the lock ball lever to come out of the lock notch in the lock ring, thereby allowing the lock ring to rotate to a position in which the housing notch is open.
2. The disc lock of claim 1 , wherein the top housing section and the bottom housing section form the antenna chamber, with the antenna chamber located inside, a space protruding tangentially from the annular shape of the lock chamber.
3. A disc lock comprising an antenna chamber, a lock ring, a top housing section, a bottom housing section assembled with the top housing section to form a housing having an annular shaped lock chamber and a housing notch, wherein the lock chamber houses a lock mechanism and the antenna chamber houses an antenna system,
wherein the lock chamber comprises a motor, which when activated by the antenna system, moves the lock mechanism from a locked state to an unlocked state or from the unlocked state to the locked state
wherein the lock mechanism comprises a lock ball cam, a lock ball, and a lock ball lever, wherein the lock ball cam is configured to put pressure on the lock ball, which pushes the lock ball lever into a lock notch in the lock ring, thereby keeping the lock ring in a position in which the housing notch is closed by the lock ring and removes the pressure from the lock ball, which allows the lock ball lever to come out of the lock notch in the lock ring, thereby allowing the lock ring to rotate to a position in which the housing notch is open.
4. The disc lock of claim 3 , wherein the top housing section and the bottom housing section form the antenna chamber, with the antenna chamber located inside a space protruding tangentially from the annular shape of the lock chamber.
