Electronic lock and method for setting up electronic lock

1 . 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.

2 . The electronic lock as claimed in claim 1 , wherein said control module is configured to operate in the opening-side setting mode when being powered on for the first time.

3 . The electronic lock as claimed in claim 1 , wherein said turning-piece module includes a shaft connected to said electronic driving module and said deadbolt so as to be driven by said electronic driving module to rotate for moving said deadbolt, a turning piece connected to one end of said shaft opposite to said deadbolt and configured to be manually operated to rotate said shaft, and a ring-shaped component fitting over said shaft to co-rotate with said shaft,

wherein said magnetic component is mounted on said ring-shaped component.

4 . A method for setting up an electronic lock as claimed in claim 1 , the method comprising:

the control module operating in the opening-side setting mode and receiving one or more of the sensing signals from the Hall sensors without controlling the electronic driving module to drive the turning-piece module to rotate;

the control module analyzing two of the sensing signals that are first received respectively from two of the Hall sensors;

the control module activating one of the left-open setting and the right-open setting based on the two of the sensing signals that are first received;

the control module controlling the electronic driving module to drive the turning-piece module to rotate only between the first position and the second position when the left-open setting has been activated, and controlling the electronic driving module to drive the turning-piece module to rotate only between the first position and the third position when the right-open setting has been activated;

upon activating the left-open setting, the control module automatically controlling the electronic driving module to drive the turning-piece module to switch between the first position and the second position once; and

upon activating the right-open setting, the control module automatically controlling the electronic driving module to drive the turning-piece module to switch between the first position and the third position once.

5 . The method as claimed in claim 4 , wherein the control module operating in the opening-side setting mode is implemented only when the control module is powered on for the first time.
