ELECTRIC DRIVE MECHANISM FOR OPERATING A LOCK
This invention describes an electric drive mechanism (120) for translating a blocking member (126) to secure or release a lock. The lock is configured as a latch lock (100), a slide bolt padlock (200), a U-shackle padlock (300) or a snap padlock (400). The blocking member (126) is supported by two or more steel balls (130) disposed in helical grooves formed on a helical member (124) to provide a self-centering and low friction drive mechanism (120), which allows an electric motor (122) connected to the helical member to be small and of low power. Unobstructed movement of the blocking member (126) is provided by an alignment or detent mechanism (160, 217, 317) or torsion spring in the snap padlock (400). An electronic control board (140) allows electronic operation of the lock via an application in a smartphone. A PCB (121) located near the electric motor provides tamper-proofing.
