Electronic lock and method for setting up electronic lock

An electronic lock comprising:

• a locking mechanism including an electronic driving module, a deadbolt, and a turning-piece module that is connected to said electronic driving module and said deadbolt, that is configured to be manually operated to rotate among a first position corresponding to a first state of said electronic lock, and a second position and a third position both corresponding to a second state of said electronic lock, and that is configured to drive said deadbolt to move between a projection position and a retraction position while rotating;
• and
• a control device including three Hall sensors that are disposed to surround a rotation axis of said turning-piece module and that are angularly spaced apart from each other, a magnetic component that is disposed on said turning-piece module so as to co-rotate with said turning-piece module relative to said Hall sensors, and a control module that is electrically connected to said Hall sensors and said electronic driving module and that is configured to control said electronic driving module to operate for driving said turning-piece module to rotate,
• wherein each of said Hall sensors is configured to detect a presence of said magnetic component and to generate a sensing signal upon detecting said magnetic component,
• wherein said control module is further configured to operate in an opening-side setting mode for activating one of a left-open setting and a right-open setting according to two of the sensing signals that are first received respectively from two of said Hall sensors without controlling said electronic driving module to drive said turning-piece module to rotate, and to control said electronic driving module to drive said turning-piece module to rotate between the first position and one of the second position and the third position according to the one of the left-open setting and the right-open setting that has been activated,
• wherein the first state of said electronic lock is a locking state and the second state of said electronic lock is an unlocking state, said deadbolt is at the projection position when said turning-piece module is at the first position, and said deadbolt is at the retraction position when said turning-piece module is at the second position and the third position,
• wherein said control module is configured to control said electronic driving module to drive said turning-piece module to rotate only between the first position and the second position when the left-open setting has been activated, and to control said electronic driving module to drive said turning-piece module to rotate only between the first position and the third position when the right-open setting has been activated,
• wherein said control module is further configured, upon activating the left-open setting, to automatically control said electronic driving module to drive said turning-piece module to switch between the first position and the second position once, and
• wherein said control module is further configured, upon activating the right-open setting, to automatically control said electronic driving module to drive said turning-piece module to switch between the first position and the third position once.
