Abstract

This disclosure provides a lock having a rotating component, the rotation of which drives the retractable movement of a latch bolt, and the rotating component is equipped with a trigger component; a first sensing component, fixedly set or arranged at the first position of the lock, where the first position is the position indicated by a knob fixedly connected to the rotating component when the lock is in the unlocked state, and when the trigger component is at the first position, the first sensing component generates a first trigger signal; a second sensing component is fixedly set or arranged at the second position of the lock, where the second position is the position indicated by the knob when the lock is in the locked state, and when the trigger component is at the second position, the second sensing component generates a second trigger signal.

First claim

What is claimed is:

1 . A lock, comprising:
a rotating component including a triggering component, wherein a rotation of the rotating component drives a retractable movement of a latch bolt; a first sensing component fixedly arranged at a first position of the lock, the first position being a position pointed to by a knob, fixedly connected to the rotating component, when the lock is in an unlocked state, wherein the first sensing component is configured to generate a first trigger signal when the triggering component is at the first position; and a second sensing component fixedly arranged at a second position of the lock, the second position being a position pointed to by the knob when the lock is in a locked state, wherein the second sensing component is configured to generate a second trigger signal when the triggering component is at the second position.

2 . The lock according to claim 1 , further comprising: a third sensing component fixedly arranged at a third position of the lock, the third position being between the first position and the second position, wherein the third sensing component is configured to send a detection signal to a control component of the lock when the third sensing component senses the triggering component.

3 . The lock according to claim 2 , wherein the control component, based on the detection signal, is configured to perform at least one of:
an unlocking action; a locking action; and a switching action from a low power mode to a working mode, wherein:
in the low power mode, one or more components of the lock in a sleep state are not powered, and
in the working mode, the one or more components of the lock in a sleep state are powered.

4 . The lock according to claim 2 , wherein the first sensing component and the second sensing component comprise photoelectric sensors, the triggering component comprises a light-blocking piece, the third sensing component comprises a Hall sensor, and the triggering component comprises a magnetic piece.

5 . The lock according to claim 2 , further comprising:
a driving component connected to the rotating component, wherein the driving component is electrically connected to the control component.

6 . The lock according to claim 2 , wherein the control component is configured to:
after receiving, from the first sensing component, the first trigger signal, generates a lock opening completion signal, wherein the rotating component is configured to continue rotating a preset angle; and after receiving, from the second sensing component, the second trigger signal, generate a lock closing completion signal, and cause the rotating component to continue rotating the preset angle, wherein the preset angle is determined by a compensation strategy.

7 . The lock according to claim 6 , wherein the control component is further configured to:
after receiving, from a terminal, a reminder message that a status of the lock is pending, control the rotating component to rotate towards the second position, wherein the reminder message is generated based on a detection that the rotating component is neither at the first position nor at the second position, and a duration of stay of the rotating component is greater than a preset duration.

8 . The lock according to claim 7 , wherein the control component is further configured to:
during the rotation of the rotating component and after receiving, from the third sensing component, the detection signal, cause the rotating component to rotate towards the first position and to point to the first position to perform an unlocking action; and during the rotation of the rotating component and after determining that no detection signal is received, cause the rotating component to continue rotating towards the second position and to point to the second position to perform a locking action.

9 . The lock according to claim 5 , wherein the control component is configured to: after determining that the driving component is not activated and after receiving, from the third sensing component, the detection signal, switch from a low power mode to a working mode, wherein:
in the low power mode, one or more components of the lock in a sleep state are not powered, and in the working mode, one or more components in the sleep state are powered.

10 . The lock according to claim 6 , wherein the control component is further configured to:
after generating the lock opening completion signal and controlling the rotating component to continue rotating the preset angle, send a first notification to a terminal, wherein the first notification indicates a successful unlocking; and after generating the lock closing completion signal and controlling the rotating component to continue rotating the preset angle, send a second notification to the terminal, wherein the second notification indicates a successful locking.

11 . A method for controlling locking and unlocking mechanisms of a lock comprising a controller, a rotating component comprising a triggering component, a first sensing component and a second sensing component, the method comprising:
receiving, by the controller, a first triggering signal or a second triggering signal, wherein the first triggering signal is generated by the first sensing component when the triggering component is in a first position, and the second triggering signal is generated by the second sensing component when the triggering component is in a second position; based on the receipt of the first triggering signal, generating a lock opening completion signal, wherein the rotating component is configured to continue rotating a preset angle, and wherein the preset angle is determined by a compensation strategy; and based on the receipt of the second triggering signal, generating a lock closing completion signal, wherein the rotating component is configured to continue rotating the preset angle.

12 . The method of claim 11 , wherein the lock comprises a third sensing component fixedly arranged at a third position of the lock, the third position being between the first position and the second position, the method further comprising:
receiving, by the controller and from a terminal, a reminder message that a status of the lock is pending; determining that the rotating component is neither at the first position nor at the second position, and a duration of stay of the rotating component is greater than a preset duration; and causing the rotating component to rotate towards the second position.

13 . The method of claim 12 , further comprising:
during the rotation of the rotating component and after receiving, from the third sensing component, a detection signal indicating that the third sensing component senses the triggering component at the third position, causing, by the controller, the rotating component to rotate towards the first position and to point to the first position to perform an unlocking action.

14 . The method of claim 12 , further comprising:
during the rotation of the rotating component and after receiving, from the third sensing component, a detection signal indicating that the third sensing component senses the triggering component at the third position, causing, by the controller, the rotating component to rotate towards the second position and to point to the second position to perform a locking action.

15 . The method of claim 12 , further comprising:
after receiving, from the third sensing component, a detection signal indicating that the third sensing component senses the triggering component at the third position, causing, by the controller, the
