Referring to FIGS. 1 to 3, an electronic lock 100 according to a first embodiment of this disclosure is adapted to be installed on a door 800 (e.g., a swing door) of an enclosed space(e.g., a room). The door 800 may be a left-hand door or a right-hand door. In this disclosure, the door 800 is an inswing door, and FIGS. 1 to 3 are viewed from a perspective of an interior of the enclosed space. For example, the electronic lock 100 is installed on an inner side of the door that faces the interior of the enclosed space. As shown in FIGS. 1 and 2, the door 800 is a left-hand door, and a plurality of hinges 801 are mounted on a right side of the door 800. On the other hand, the door 800 shown in FIG. 3 is a right-hand door, and a plurality of hinges 801 are mounted on a left-side of the door 800.

Referring to FIGS. 1, 2, 4 and 7, the electronic lock 100 according to the first embodiment of this disclosure includes a housing 2, a locking mechanism 3, and a control device 4. The control device 4 is electrically connected to the locking mechanism 3.

The locking mechanism 3 includes an electronic driving module 31 that is disposed in the housing 2, a deadbolt 33, and a turning-piece module 32 (e.g., a thumb turn) that is connected to the electronic driving module 31 and the deadbolt 33 (see FIG. 19). A part of the turning-piece module 32 protrudes outside of the housing 2.

The electronic driving module 31 is controlled by the control device 4 to drive the turning-piece module 32 to rotate. In this embodiment, the electronic driving module 31 includes a motor 311 that is electrically connected to the control device 4, and a transmission system 312 that is connected between the motor 311 and the turning-piece module 32. Since there is a multitude of available types of electronic driving modules, and since the electronic driving module 31 is not the emphasis of this disclosure, details of the electronic driving module 31 will not be further described hereinafter for the sake of brevity. For example, the transmission system 312 is a set of gears.

Referring to FIGS. 1, 2, 3 and 5, the turning-piece module 32 is configured to rotate among a first position (see FIG. 1) corresponding to a first state of the electronic lock 100, and a second position (see FIG. 2) and a third position (see FIG. 3) both corresponding to a second state of the electronic lock 100. In this embodiment of this disclosure, the first state of the electronic lock 100 is a locking state, and the first position of the turning-piece module 32 is a locking position for locking the door 800 (see FIG. 1); the second state of the electronic lock 100 is an unlocking state, the second position of the turning-piece module 32 is a left-open unlocking position for unlocking the door 800 (i.e. the left-hand door) (see FIG. 2), and the third positon of the turning-piece module 32 is a right-open unlocking position for unlocking the door 800 (i.e. the right-hand door) (see FIG. 3). The turning-piece module 32 is configured to rotate in one of a first manner where the turning-piece module 32 is manually operated and a second manner where the turning-piece module 32 is driven by the electronic driving module 31.

The turning-piece module 32 is further configured to, while rotating, drive the deadbolt 33 to move between a projection position where the deadbolt 33 projects from the door 800 (see FIG. 1) into a door strike (not shown), and a retraction position where the deadbolt 33 retracts into the door 800 (see FIGS. 2 and 3). In the first embodiment, the deadbolt 33 is at the projection position when the turning-piece module 32 is at the first position (i.e., the electronic lock 100 is in the locking state), and the deadbolt 33 is at the retraction position when the turning-piece module 32 is at the second position and the third position (i.e., the electronic lock 100 is in the unlocking state). Specifically, the turning-piece module 32 drives the deadbolt 33 to move from the retraction position to the projection position when being rotated from the second position or the third position to the first position, and drives the deadbolt 33 to move back to the retraction position when being rotated from the first position to the second position or the third position.

Referring to FIGS. 3, to 6, in this embodiment, the turning-piece module 32 includes a shaft 320 connected to the electronic driving module 31 and the deadbolt 33. The shaft 320 engages with a gear of the transmission system 312 so as to be driven by the electronic driving module 31 to rotate for further moving the deadbolt 33. The turning-piece module 32 further includes a turning piece 321 connected to one end of the shaft 320 opposite to the deadbolt 33. The turning piece 321 is disposed outside of the housing 2, and is configured to be manually operated to rotate the shaft 320, thereby moving the deadbolt 33 to switch between the projection position and the retraction position. The turning-piece module 32 further includes a ring-shaped component 322 fitting over the shaft 320 to co-rotate with the shaft 320. A connection structure between the turning piece 321 and the deadbolt 33 is well-known in the art, so details thereof will be omitted herein for the sake of brevity.

Referring to FIGS. 5, to 8, the control device 4 includes three Hall sensors 41, a magnetic component 42, and a control module 43 that is electrically connected to the Hall sensors 41 and the motor 311 of the electronic driving module 31.

The Hall sensors 41 are disposed to surround a rotation axis of the turning-piece module 32, and are angularly spaced apart from each other. In this embodiment, for adjacent two of the Hall sensors 41, a difference between angular positions respectively of these two Hall sensors 41 with respect to the rotation axis of the turning-piece module 32 is 90 degrees.

Referring to FIGS. 5, and 7 to 11, the magnetic component 42 is fixedly mounted on the ring-shaped component 322 to co-rotate with the turning-piece module 32 relative to the Hall sensors 41. When the turning-piece module 32 is in one of the first position, the second position and the third position, the magnetic component 42 is aligned with one of the Hall sensors 41 in a direction along the rotation axis. Each one of the Hall sensors 41 is configured to detect a presence of the magnetic component 42 and to generate a sensing signal upon detecting the magnetic component 42. According to the first embodiment of this disclosure, when the turning-piece module 32 is in the first position (as shown in FIG. 8), a right one of the Hall sensors 41 generates a sensing signal (hereinafter referred to as “signal B”); when the turning-piece module 32 is in the second position (as shown in FIG. 10), an upper one of the Hall sensors 41 generates a sensing signal (hereinafter referred to as “signal C”); and when the turning-piece module 32 is in the third position (as shown in FIG. 11), a lower one of the Hall sensors 41 generates a sensing signal (hereinafter referred to as “signal A”).

The control module 43 is configured to control the electronic driving module 31 to operate. When operating, the electronic driving module 31 drives the turning-piece module 32 to rotate. The control module 43 is further configured to operate in an opening-side setting mode for activating one of a left-open setting and a right-open setting based on two of the sensing signals that are first received respectively from two of the Hall sensors 41 without controlling the electronic driving module 31 to drive the turning-piece module 32 to rotate. The control module 43 is configured to operate in the opening-side setting mode when powered on for the first time. The control module 43 may be programmed according to the left-open setting, so as to electrically control the electronic driving module 31 to drive the turning-piece module 32 to rotate only between the first position and the second position when activating the left-open setting. On the other hand, the control module 43 may be programmed according to the right-open setting, so as to electrically control the electronic driving module 31 to drive the turning-piece module 32 to rotate only between the first position and the third position when activating the right-open setting.

The control module 43 is further configured, upon activating the left-open setting, to automatically control the electronic driving module 31 to drive the turning-piece module 32 to switch between the first position and the second position once, while upon activating the right-open setting, to automatically control the electronic driving module 31 to drive the turning-piece 32 to switch between the first position and the third position once.

To install the electronic lock 100 on the door 800, the deadbolt 33 is set to be in the projection position, and the turning-piece module 32 is set to be in the first position. Subsequently, the deadbolt 33 is connected to the turning-piece module 32.

Referring to FIGS. 8, and 10 to 12, after the electronic lock 100 is installed on the door 800, the electronic lock 100 is powered on for the first time such that the electronic lock 100 is activated to implement a method for setting up the electronic lock 100. Specifically, the method is implemented to automatically determine whether the door 800 on which the electronic lock 100 is installed is a left-hand door or a right-hand door and then to automatically activate the left-open setting or the right-open setting according to the determination. The method for setting up the electronic lock 100 includes steps 901 to 904.

In step 901, the control module 43 operates in the opening-side setting mode to wait for the sensing signals from the Hall sensors 41 when powered on for the first time. In step 901, the control module 43 is operating without controlling the electronic driving module 31 to drive the turning-piece module 32 to rotate.

At this stage, a user may manually turn the turning piece 321 to make the turning-piece module 32 rotate between the first position and the second position for the left-hand door, or rotate between the first position and the third position for the right-hand door. The magnetic component 42, which co-rotates with the turning-piece module 32, is also moved to be aligned with two of the Hall sensors 41 in sequence. When the two of the Hall sensors 41 detect the presence of the magnetic component 42, the two of the Hall sensors 41 generate the sensing signals in sequence and transmit the sensing signals to the control module 43, and the control module 43 receives the sensing signals.

In step 902, the control module 43 analyzes two of the sensing signals that are first received respectively from two of the Hall sensors 41 (hereinafter referred to as “first-received signals”) in the opening-side setting mode. based on the first-received signals (i.e., signal A and signal B, or signal C and signal B), the control module 43 may determine which two of the Hall sensors 41 sent the first-received signals.

In step 903, the control module 43 activates one of the left-open setting and the right-open setting according to the first-received signals. When the control module 43 determines that the first-received signals are signal C and signal B, the control module 43 activates the left-open setting. On the other hand, when the control module 43 determines that the first-received signals are signal A and signal B, the control module 43 activates the right-open setting.

In step 904, upon activating said one of the left-open setting and the right-open setting, the control module 43 automatically controls the electronic driving module 31 to drive the turning-piece module 32 to switch between the first position and a corresponding one of the second position and the third position once. Specifically, upon activating the left-open setting, the control module 43 automatically controls the electronic driving module 31 to drive the turning-piece module 32 to switch between the first position and the second position once, whereby the deadbolt 33 is driven by the turning-piece module 32 to switch between the projection position and the retraction position once; and upon activating the right-open setting, the control module 43 automatically controls the electronic driving module 31 to drive the turning-piece module 32 to switch between the first position and the third position once, whereby the deadbolt 33 is driven by the turning-piece module 32 to switch between the projection position and the retraction position once. By completing the foregoing operation of step 904, the user may be aware that the electronic lock 100 has been set.

In some embodiments of this disclosure, the control module 43 is configured to operate in the opening-side setting mode when being powered on for the first time. However, it should be understood that in other embodiments, the control device 4 may further include a switch that is operable by a user to activate the control module 43 to operate in the opening-side setting mode. As various ways may be employed to activate the control module 43 to operate in the opening-side setting mode, this disclosure is not limited to the above.

Referring to FIGS. 13 to 15, according to a second embodiment of this disclosure, the first state of the electronic lock 100 is the unlocking state, and the first position of the turning-piece module 32 is an unlocking position for unlocking the door 800 (see FIG. 13); the second state of the electronic lock is the locking state, the third position of the turning-piece module 32 is a left-open locking position for locking the door 800 (i.e. the left-hand door) (see FIG. 14), and the second positon of the turning-piece module 32 is a right-open locking position for locking the door 800 (i.e. the right-hand door) (see FIG. 15). In the second embodiment, the deadbolt 33 is at the retraction position when the turning-piece module 32 is at the first position (i.e., the electronic lock 100 is in the unlocking state), and the deadbolt 33 is at the projection position when the turning-piece 32 is at the second position and the third position (i.e., the electronic lock 100 is in the locking state). Specifically, the turning-piece module 32 drives the deadbolt 33 to move from the projection position to the retraction position when being rotated from the second position or the third position to the first position, and drives the deadbolt 33 to move from the retraction position to the projection position when being rotated from the first position to the second position or the third position.

In this embodiment, to install the electronic lock 100 on the door 800, the deadbolt 33 is set to be in the retraction position, and the turning-piece module 32 is set to be in the first position. Subsequently, the deadbolt 33 is connected to the turning-piece module 32.

Referring to FIGS. 13 to 18, according to the second embodiment of this disclosure, when the turning-piece module 32 is in the first position (see FIGS. 13 and 16), the right one of the Hall sensors 41 generates the signal B; when the turning-piece module 32 is in the third position (see FIGS. 14 and 17), the lower one of the Hall sensors 41 generates the signal A; and when the turning-piece module 32 is in the second position (see FIGS. 15 and 18), the upper one of the Hall sensors 41 generates the signal C. When the control module 43 determines that the first-received signals are the signal A and the signal B, the control module 43 activates the left-open setting. On the other hand, when the control module 43 determines that the first-received signals are the signal C and the signal B, the control module 43 activates the right-open setting. Upon activating said one of the left-open setting and the right-open setting, the control module 43 automatically controls the electronic driving module 31 to drive the turning-piece module 32 to switch between the first position and the corresponding one of the second position and the third position once.
