1. An electronic lock comprising:
a deadbolt operable to convert between a locking state and an unlocking state;
a driver mechanism;
a transmission mechanism including
a transmission gear that has a shaft hole extending along a rotating axis of said transmission gear, and that is driven by said driver mechanism to rotate when said driver mechanism is actuated,
a resilient unit that is mounted to and co-rotatable with said transmission gear, and that defines a movement space corresponding in position to said shaft hole, and
a rotary member that is connected to said deadbolt, that is operable to rotate relative to said transmission gear between a locking position and an unlocking position, and that has
a shaft portion extending through said shaft hole, rotatable relative to said transmission gear about the rotating axis, and having an outer surrounding surface, and
at least one protruding portion protruding from said outer surrounding surface, and rotating about the rotating axis in said movement space when said rotary member rotates, said resilient unit being capable of pushing said at least one protruding portion to urge said rotary member to rotate between the locking position and the unlocking position when said transmission gear rotates, said deadbolt being correspondingly converted between the locking state and the unlocking state when said rotary member rotates between the locking position and the unlocking position; and
a control mechanism connected to said rotary member, and ceasing operation of said driver mechanism when detecting that said rotary member has been rotated to one of the locking position and the unlocking position;
wherein said control mechanism is configured to store a locking procedure and an unlocking procedure that are executed one at a time;
wherein, when said control mechanism executes the unlocking procedure, said control mechanism controls said driver mechanism to drive said transmission gear to rotate from an initial position to a first position in a first rotating direction so that said resilient unit urges said rotary member to rotate from the locking position to the unlocking position, and said control mechanism subsequently controls said driver mechanism to drive said transmission gear to rotate relative to said rotary member from the first position to the initial position in a second rotating direction opposite to the first rotating direction;
wherein, when said control mechanism executes the locking procedure, said control mechanism controls said driver mechanism to drive said transmission gear to rotate from the initial position to a second position in the second rotating direction so that said resilient unit urges said rotary member to rotate from the unlocking position to the locking position, and said control mechanism subsequently controls said driver mechanism to drive said transmission gear to rotate relative to said rotary member from the second position to the initial position in the first rotating direction;
wherein, when said transmission gear is at the initial position, said rotary member is operable to rotate relative to said transmission gear between the unlocking position and the locking position without driving rotation of said transmission gear;
wherein said control mechanism includes
a lock orientation member that is fixedly sleeved onto said shaft portion of said rotary member and that is co-rotatable with said rotary member,
a first detecting member, and
a control unit that is signally coupled to said first detecting member and said driver mechanism;
wherein said lock orientation member is rotatable relative to said first detecting member, said first detecting member being convertible among three detecting states upon the relative rotation of said lock orientation member, and generating first detecting signals that respectively correspond to the detecting states;
wherein said control mechanism is further configured to store a locked signal set and an unlocked signal set, said control unit determining whether said first detecting member generates the first detecting signals that conform with one of the locked signal set and the unlocked signal set;
wherein, when said control mechanism executes the unlocking procedure, said control unit ceases the operation of said driver mechanism while determining that the first detecting signals generated by said first detecting member conform with the unlocked signal set; and
wherein, when said control mechanism executes the locking procedure, said control unit ceases the operation of said driver mechanism while determining that the first detecting signals generated by said first detecting member conform with the locked signal set.
