Electronically operated lock

An electronically driven lock comprising:

• a bolt assembly having a latch therein;
• a transmission shaft extending through the bolt assembly for actuating the latch;
• a lock unit comprising a base, a top cover attached on the base, a handle assembly, a clutch and a driving unit;
• the handle assembly comprising a pinion and a controller shaft, the controller shaft comprising a first gear portion, the controller shaft receiving the transmission shaft therein;
• the clutch comprising a sleeve and a second gear portion arranged at the sleeve, the driving unit comprising a gear plate, the gear plate comprising a third gear portion arranged at a circumferential wall thereof;
• the clutch being received in the gear plate and actuatable thereby;
• the second gear portion of the clutch meshing with the pinion of the handle assembly, and the pinion of the handle assembly meshing with the first gear portion of the controller shaft.

An electrically operated lock equipped with manual operation mechanism, comprising:

• a stationary base;
• a transmission shaft rotatable relative to the base and extending in a first direction, said transmission shaft being adapted to be rotated to two positions deciding whether a lock bolt is allowed to move along a second direction perpendicular to said first direction;
• an inner lock unit actuating the transmission shaft to rotate clockwise or counterclockwise, said inner lock unit including:
• a driving unit having a gear plate actuated by a motor, said gear plate defining a driving protrusion thereon;
• and
• a clutch unit connected, via a pinion, to a mating shaft linked to said transmission shaft, said clutch unit defining a driven protrusion engaged with said driving protrusion;
• wherein
• said driving unit and said clutch unit are concentrically rotated relative to the base.
