Detailed Implementation

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] As shown in Figures 1 to 12, this application proposes a lock. As shown in Figures 1 and 2, the lock includes a deadbolt 1000, a drive mechanism 2000, a trigger mechanism 3000, and a controller 4000. The deadbolt 1000 includes a lock body 1100 and a bolt 1200 movably connected to the lock body 1100. The bolt 1200 can be configured to have a locked position and an unlocked position. Therefore, the bolt 1200 can move to the locked position, thereby locking the lock, or the bolt 1200 can move to the unlocked position, thereby unlocking the lock.

[0064] The drive mechanism 2000 includes a knob 2100 and a drive member 2200. The knob 2100 has at least a first rotational position and a second rotational position. Therefore, the knob 2100 can be rotated to either the first rotational position or the second rotational position. As shown in Figures 3 and 4, when the knob 2100 is in the horizontal position shown in Figure 3, it has rotated to the first rotational position; when the knob 2100 is in the vertical position shown in Figure 4, it has rotated to the second rotational position. Furthermore, the knob 2100 is driven connected to the latch 1200, and the drive member 2200 is driven connected to the knob 2100.

[0065] Meanwhile, the triggering mechanism 3000 includes a detection component 3100 and a triggering component 3200. The detection component 3100 includes an unlocking detection element 3110 and a locking detection element 3120. The triggering component 3200 includes an unlocking trigger element 3210 and at least two locking trigger elements 3220, meaning that there can be two or more locking trigger elements 3220. This application uses two locking trigger elements 3220 as an example, with the two locking trigger elements 3220 respectively disposed on both sides of the unlocking trigger element 3210.

[0066] The unlocking detection element 3110 and the locking detection element 3120 of the detection component 3100 are used to cooperate with the unlocking trigger element 3210 and the two locking trigger elements 3220 of the trigger component 3200. The unlocking trigger element 3210 is used to trigger the unlocking detection element 3110, and the locking trigger element 3220 is used to trigger the locking detection element 3120. One of the detection component 3100 and the trigger component 3200 is disposed on the knob 2100, and the other is disposed on the lock body 1100. Therefore, when the unlocking detection element 3110 and the locking detection element 3120 of the detection component 3100 cooperate with the unlocking trigger element 3210 and the two locking trigger elements 3220 of the trigger component 3200, the trigger component 3200 can be used to make the detection component 3100 emit a trigger signal as the knob 2100 rotates. The controller 4000 is used to acquire the trigger signal, and after acquiring the trigger signal, the controller 4000 can determine the rotation scheme of the knob 2100 and the installation direction of the deadbolt 1000 based on the trigger signal.

[0067] When the above-mentioned lock is applied to a left-opening door, the knob 2100 is rotated to the horizontal state shown in Figure 3, indicating that the knob 2100 has been rotated to the first rotation position. The bolt 1200 also extends out of the deadbolt 1000. At this time, the knob 2100 can be rotated clockwise as shown in Figure 7, so that the knob 2100 is rotated to the vertical state shown in Figure 4, indicating that the knob 2100 has been rotated to the second rotation position. At this time, one of the locking triggers 3220 of the triggering component 3200 (the locking trigger 3220 on the left in Figure 7) triggers the locking detection component 3120 of the detection component 3100, thereby activating the detection component 3100 to issue a locking signal. At this time, the bolt 1200 also retracts into the deadbolt 1000 and moves to the locking position.

[0068] When the above-mentioned lock is applied to a right-opening door, the knob 2100 is rotated to the horizontal state shown in Figure 3, indicating that the knob 2100 has been rotated to the first rotation position. The bolt 1200 also extends out of the deadbolt 1000. At this time, the knob 2100 can be rotated counterclockwise as shown in Figure 8, so that the knob 2100 is rotated to the vertical state shown in Figure 4, indicating that the knob 2100 has been rotated to the second rotation position. At this time, one of the locking triggers 3220 of the triggering component 3200 (the locking trigger 3220 on the right in Figure 8) triggers the locking detection component 3120 of the detection component 3100, thereby activating the detection component 3100 to issue a locking signal. At this time, the bolt 1200 also retracts into the deadbolt 1000 and moves to the locking position.

[0069] Therefore, the aforementioned lock, equipped with a detection component 3100 and a triggering component 3200, and defining the interaction between the unlocking detection element 3110 and the locking detection element 3120 of the detection component 3100 and the unlocking triggering element 3210 and the two locking triggering elements 3220 of the triggering component 3200, can determine the rotation scheme of the knob 2100 and the installation direction of the deadbolt 1000 based on the triggering signal generated during the interaction. Thus, the unlocking detection element 3110 and the locking detection element 3120 built into the lock can always maintain a definite state. During installation and use, regardless of whether the lock is installed with the door opening direction to the left or right, it can quickly identify whether the current installation direction is left-opening or right-opening, thereby determining the rotation scheme that the lock should achieve in the current installation direction, and determining the installation direction of the deadbolt 1000 based on the rotation scheme.

[0070] Based on the above method, the lock no longer needs to be designed with two different models for different installation directions (left-opening or right-opening). Only one universal model needs to be produced to accommodate both left-opening and right-opening installation directions. After installation, the rotation scheme of the knob 2100 and the installation direction of the deadbolt 1000 can be determined by the cooperation of the detection component 3100 and the trigger component 3200 to obtain the corresponding trigger signal. This effectively reduces the difficulty of lock installation, eliminates installation restrictions, simplifies the lock installation and calibration process, and allows for quick and accurate determination of the lock's installation direction, applicable to both left-opening and right-opening installation directions.

[0071] When the unlocking detection element 3110 and the locking detection element 3120 of the detection component 3100 cooperate with the unlocking trigger element 3210 and the two locking trigger elements 3220 of the trigger component 3200, the generated trigger signals include unlocking signals and locking signals. As shown in Figures 3 and 4, in one embodiment, when the knob 2100 is rotated to the first rotation position, the detection component 3100 sends an unlocking signal, and the bolt 1200 moves to the unlocking position.

[0072] For example, when the knob 2100 can be rotated to the horizontal state shown in Figure 3, it means that the knob 2100 has been rotated to the first rotation position. When the knob 2100 is rotated to the first rotation position, the knob 2100 will cooperate with the detection component 3100, thereby triggering the detection component 3100 to send an unlocking signal. At this time, as shown in Figure 3, the bolt 1200 also extends out from the deadbolt 1000 and moves to the unlocking position. At this time, the first rotation position, the unlocking signal and the unlocking position can be logically related.

[0073] When the knob 2100 is rotated to the second rotation position, the detection component 3100 sends a locking signal, and the latch 1200 moves to the locking position. For example, when the knob 2100 can be rotated to the vertical position shown in Figure 4, it means that the knob 2100 has rotated to the second rotation position. When the knob 2100 is rotated to the second rotation position, the knob 2100 will cooperate with the detection component 3100, thereby triggering the detection component 3100 to send a locking signal. At this time, the latch 1200 also retracts into the deadbolt 1000 and moves to the locking position. This makes the second rotation position, the locking signal and the locking position logically related.

[0074] Regarding the rotation of knob 2100, knob 2100 can be designed for various rotation modes as needed, not limited to fixed-axis rotation. In one embodiment, when knob 2100 rotates along a fixed axis, knob 2100 is configured to have a virtual axis of rotation, which is a virtual axis defining the rotation of knob 2100. Therefore, the drive member 2200 can be used to drive knob 2100 to rotate along the virtual axis of rotation, rotating in a fixed-axis manner. At this time, the two locking triggers 3220 can be arranged in a centrally symmetrical state relative to the virtual axis of rotation.

[0075] As the knob 2100 rotates, the trigger component 3200 triggers the detection component 3100 to emit a trigger signal. During this process, the trigger component 3200 can be directly or indirectly connected to the knob 2100. Therefore, as the knob 2100 rotates, the unlocking trigger 3210 and the two locking triggers 3220 in the trigger component 3200 will move accordingly. For example, in one embodiment, the trigger component 3200 may further include a trigger mounting plate 3230, which is mounted on the knob 2100, allowing the trigger mounting plate 3230 to also rotate along the virtual rotation axis with the knob 2100. In this case, the rotation of the knob 2100 will drive the trigger mounting plate 3230 to rotate synchronously.

[0076] Based on the above structural configuration, the vertical distance of the unlocking detection element 3110 relative to the virtual rotation axis is defined as a first detection distance range. The unlocking trigger element 3210 is mounted on the trigger mounting plate 3230, and the vertical distance of the unlocking trigger element 3210 relative to the virtual rotation axis is defined as a first trigger distance. In this case, since the first trigger distance is limited to the first detection distance range, the unlocking trigger element 3210 can form contact with the unlocking detection element 3110 based on the relative distance limitation relationship between the first trigger distance and the first detection distance range, thereby triggering the unlocking detection element 3110 through relative contact.

[0077] Based on the same principle, the vertical distance of the locking detection element 3120 relative to the virtual rotation axis can be defined as a second detection distance range. The second detection distance range is different from the first detection distance range. The two locking trigger elements 3220 are symmetrically mounted on the trigger mounting plate 3230 with respect to the virtual rotation axis. The vertical distance of the locking trigger element 3220 relative to the virtual rotation axis is defined as the second trigger distance. At this time, the second trigger distance is defined within the second detection distance range. Therefore, the locking trigger element 3220 can form contact with the locking detection element 3120 based on the relative distance definition relationship between the second trigger distance and the second detection distance range, and thus trigger the locking detection element 3120 through relative contact.

[0078] Furthermore, since the second detection distance range differs from the first detection distance range, this limitation on the relative distance can be used to ensure that the first triggering distance only forms a relative distance limitation relationship with the first detection distance range. This ensures that the unlocking trigger 3210 only contacts the unlocking detection element 3110 during movement, avoiding contact with the locking detection element 3120, and thus triggering the unlocking detection element 3110 through relative contact. Similarly, this limitation can also be used to ensure that the second triggering distance only forms a relative distance limitation relationship with the second detection distance range. This ensures that the locking trigger 3220 only contacts the locking detection element 3120 during movement, avoiding contact with the unlocking detection element 3110, and thus triggering the locking detection element 3120 through relative contact.

[0079] Taking the embodiments shown in Figures 5 to 8 as an example, the unlocking detection element 3110 and the locking detection element 3120 of the detection component 3100 can be located at the upper and lower relative positions shown in Figure 5, respectively. The unlocking trigger element 3210 and the two locking trigger elements 3220 of the trigger component 3200 are relatively fixed in position. For example, the unlocking trigger element 3210 and the two locking trigger elements 3220 of the trigger component 3200 are fixed in relative position by forming an integral shape through a disc-like structure shown in Figure 5. At this time, the trigger component 3200 can be set between the unlocking detection element 3110 and the locking detection element 3120 of the detection component 3100. The trigger component 3200 achieves contact triggering with the unlocking detection element 3110 or the locking detection element 3120 by rotating on a fixed axis between the unlocking detection element 3110 and the locking detection element 3120 of the detection component 3100.

[0080] At this time, as shown in Figures 5 and 6, the first detection distance range represents the straight-line distance between the virtual rotation axis of the trigger component 3200 and the upper unlocking detection component 3110, and the second detection distance range represents the straight-line distance between the virtual rotation axis of the trigger component 3200 and the lower locking detection component 3120. The fact that the first detection distance range and the second detection distance range are different indicates that the straight-line distance between the virtual rotation axis of the trigger component 3200 and the upper unlocking detection component 3110 is different from the straight-line distance between the virtual rotation axis of the trigger component 3200 and the lower locking detection component 3120.

[0081] Therefore, the first triggering distance of the unlocking trigger 3210 relative to the virtual rotation axis defines the rotation radius of the unlocking trigger 3210 during the fixed-axis rotation of the trigger assembly 3200. This ensures that the unlocking trigger 3210 maintains the same rotation radius during the fixed-axis rotation of the trigger assembly 3200, guaranteeing that the unlocking trigger 3210 can contact the unlocking detection element 3110 during movement. Similarly, the second triggering distance of the locking trigger 3220 relative to the virtual rotation axis defines the rotation radius of the locking trigger 3220 during the fixed-axis rotation of the trigger assembly 3200. This ensures that the locking trigger 3220 maintains the same rotation radius during the fixed-axis rotation of the trigger assembly 3200, guaranteeing that the locking trigger 3220 can contact the unlocking detection element 3110 during movement.

[0082] Therefore, by defining the first detection distance range, the second detection distance range, the first trigger distance, and the second trigger distance, the first trigger distance is limited to a relative distance relationship only with the first detection distance range, and the second trigger distance is limited to a relative distance relationship only with the second detection distance range. Thus, by defining these relative distances, it can be ensured that during the fixed-axis rotation of the trigger assembly 3200, the unlocking trigger 3210 only contacts the unlocking detection element 3110, avoiding contact with the locking detection element 3120, and the locking trigger 3220 only contacts the locking detection element 3120, avoiding contact with the unlocking detection element 3110.

[0083] Referring again to Figures 1 and 2, in one embodiment, the drive mechanism 2000 may further include a first transmission member 5000 and a second transmission member 6000. The first transmission member 5000 is drivenly connected to the knob 2100 and the latch 1200, respectively, and the second transmission member 6000 is drivenly connected to the drive member 2200. The first transmission member 5000 and the second transmission member 6000 can be configured to have a engaged state and a disengaged state. In the engaged state, the first transmission member 5000 and the second transmission member 6000 form a transmission connection, enabling the latch 1200 to move between the locked position and the unlocked position via the first transmission member 5000. In the disengaged state, the first transmission member 5000 and the second transmission member 6000 are disengaged. Therefore, based on the engagement and disengagement states between the first transmission member 5000 and the second transmission member 6000, the drive member 2200 is used to drive the second transmission member 6000 to rotate, thereby controlling the second transmission member 6000 and the first transmission member 5000 to switch between the engagement and disengagement states.

[0084] Those skilled in the art can select appropriate structures or components to construct the first transmission member 5000 and the second transmission member 6000 according to requirements, thereby realizing the engagement and disengagement states between the first transmission member 5000 and the second transmission member 6000. For example, the first transmission member 5000 may be a component with a rotating shaft or similar structure, and the second transmission member 6000 may be a component with a gear set or similar structure, as long as it can smoothly switch between the engagement and disengagement states of the first transmission member 5000 and the second transmission member 6000 in the lock; no limitation is made here. In addition, in one embodiment, the first transmission member 5000 may be provided with a first clutch portion, and the second transmission member 6000 may be provided with a second clutch portion for cooperating with the first clutch portion. At this time, when the first transmission member 5000 and the second transmission member 6000 are in the engaged state, the first clutch part can be used to abut against the second clutch part, thereby realizing the engaged state of the first transmission member 5000 and the second transmission member 6000 in the lock. When the first transmission member 5000 and the second transmission member 6000 are in the disengaged state, the first clutch part can be used to disengage from the second clutch part, thereby realizing the disengaged state of the first transmission member 5000 and the second transmission member 6000 in the lock.

[0085] Based on the lock provided above, this application also provides a method of using the lock, which may include the following steps:

[0086] First, as shown in Figure 4, the controller 4000 of the lock can control the drive 2200 to drive the knob 2100 to rotate to the second rotation position. Rotating the knob 2100 to the second rotation position can lock the lock. As shown in Figure 7 or Figure 8, one of the locking triggers 3220 triggers the locking detection 3120, which in turn triggers the locking detection 3120 to send a locking signal, causing the bolt 1200 to retract into the deadbolt 1000 and move the bolt 1200 to the locked position.

[0087] Subsequently, as shown in Figure 3, the controller 4000 of the lock can control the drive 2200 to drive the knob 2100 to rotate from the second rotation position to the first rotation position. Rotating the knob 2100 to the first rotation position can unlock the lock. As shown in Figure 5 or Figure 6, the unlocking trigger 3210 triggers the unlocking detection 3110, which in turn triggers the unlocking detection 3110 to send an unlocking signal, causing the bolt 1200 to extend out of the deadbolt 1000 and move to the unlocking position.

[0088] Therefore, it can be seen that by controlling the knob 2100 through the controller 4000, locking and unlocking signals can be generated respectively, forming a trigger signal. At this time, the controller 4000 can continue to acquire the trigger signal emitted by the detection component 3100, determine the rotation scheme of the knob 2100 based on the trigger signal, and then determine the installation direction of the deadbolt 1000 based on the rotation scheme. Therefore, after the lock is installed, the installation direction of the lock has not yet been determined. At this time, the controller 4000 can acquire the correlation between the second rotation position, the locking signal, and the locking position when controlling the knob 2100 to perform different rotation movements. Similarly, it can also acquire the correlation between the first rotation position, the unlocking signal, and the unlocking position, and then determine the rotation scheme under this correlation, determine the installation direction under the current installation situation, and determine the future locking and unlocking of the lock.

[0089] Since the unlocking and locking states of the deadbolt 1000 can be determined after the lock is installed, the installation direction of the lock can be determined accordingly. After the lock is installed, the execution plan of the lock can be determined based on the detection results, and the locking and unlocking can be performed according to the detection results. The above-mentioned lock is equipped with a detection component 3100 and a trigger component 3200. The unlocking detection component 3110 and the locking detection component 3120 of the detection component 3100, as well as the unlocking trigger component 3210 and the two locking trigger components 3220 of the trigger component 3200, all have fixed positions and are limited to fixed cooperation methods. Therefore, the lock provided in this application can determine the installation direction at an opportune time to adapt to different schemes of left-opening and right-opening doors. When producing this lock, it is no longer necessary to design two different models for different installation directions according to the installation direction of left-opening doors or right-opening doors. That is, only one general model of lock needs to be produced to adapt to the installation direction of left-opening doors or right-opening doors. It effectively reduces the difficulty of lock installation and does not require restrictions on installation conditions, simplifying the lock installation and calibration process.

[0090] Furthermore, in the step of controlling the drive member 2200 to drive the knob 2100 to rotate to the second rotation position, those skilled in the art can use various suitable methods to control the rotation of the knob 2100. For example, in one embodiment, this step may include the following steps:

[0091] Based on the position of the knob 2100 obtained by the controller 4000, when the controller 4000 receives feedback that the knob 2100 is not initially in the second rotation position, the drive unit 2200 can be used to drive the knob 2100 to rotate to the second rotation position. The drive unit 2200 can be an active drive device such as a drive motor. The knob 2100 can rotate to any position other than the second rotation position in response to the controller 4000, so that after receiving feedback, the controller 4000 will drive the knob 2100, which is not in the second rotation position, to rotate to the second rotation position. That is, when the knob 2100 is already in the second rotation position, the controller 4000 will not perform the operation of driving the knob 2100 to rotate to the second rotation position.

[0092] Referring again to Figures 5 and 6, in one embodiment, the unlocking detection element 3110 includes a first unlocking trigger point and a second unlocking trigger point arranged sequentially along a first direction. The first unlocking trigger point and the second unlocking trigger point can be set to two different positions of the unlocking detection element 3110. For example, the first unlocking trigger point can be set to the position where the unlocking trigger element 3210 contacts the right side of the unlocking detection element 3110 when the unlocking trigger element 3210 rotates to the left in Figure 5. At this time, the second unlocking trigger point can be set to the position where the unlocking trigger element 3210 contacts the left side of the unlocking detection element 3110 when the unlocking trigger element 3210 rotates to the right in Figure 6. At this time, the first direction is the direction of the unlocking detection element 3110 from right to left and the counterclockwise rotation direction of the trigger component 3200.

[0093] In addition, the first unlocking trigger point and the second unlocking trigger point can also be arranged in the opposite direction to the above settings. That is, the first unlocking trigger point can be set to the position where the unlocking trigger 3210 contacts the left side of the unlocking detection member 3110 when the unlocking trigger 3210 rotates to the right in Figure 6. At this time, the first unlocking trigger point can be set to the position where the unlocking trigger 3210 contacts the right side of the unlocking detection member 3110 when the unlocking trigger 3210 rotates to the left in Figure 5. At this time, the first direction mentioned above is the direction of the unlocking detection member 3110 from left to right, and the clockwise rotation direction of the trigger assembly 3200.

[0094] Therefore, those skilled in the art can set the aforementioned first direction according to actual needs, and no limitation is made here. Based on the above setting of the first direction, in different settings of embodiments, in the execution steps of the controller 4000, which involve acquiring the trigger signal emitted by the detection component 3100, determining the rotation scheme of the knob 2100 based on the trigger signal, and determining the installation direction of the deadbolt 1000 based on the rotation scheme, the execution steps may include:

[0095] When the controller 4000 controls the knob 2100 to rotate to the first rotation position, the unlocking trigger 3210 triggers the first unlocking trigger point, and the detection component 3100 sends a first unlocking signal. At this time, the controller 4000 can immediately acquire the first unlocking signal and determine, based on the first unlocking signal, that the knob 2100 is rotating along a first rotation scheme, and based on the first rotation scheme, determine that the lock 1000 is in a first installation direction. Therefore, the current logic determines that the lock is installed in the aforementioned first direction, and this unlocking and locking logic will be executed in all future use.

[0096] When the controller 4000 controls the knob 2100 to rotate to the first rotation position, the unlocking trigger 3210 triggers the second unlocking trigger point, and the detection component 3100 sends a second unlocking signal. At this time, the controller 4000 can immediately acquire the second unlocking signal and determine, based on the second unlocking signal, that the knob 2100 is rotating along the second rotation scheme, and based on the second rotation scheme, determine that the lock 1000 is in the second installation direction. Therefore, the current logic determines that the lock is installed in the aforementioned second direction, and this unlocking and locking logic will be executed in all future use.

[0097] Referring again to Figures 9 to 12, this application provides a method of using the lock, wherein the detection component 3100 may further include a judgment detection element 3130, which is disposed between the unlocking detection element 3110 and the locking detection element 3120. As shown in Figure 9, the locking detection element 3120, the judgment detection element 3130, and the unlocking detection element 3110 are arranged sequentially along the aforementioned first direction, such that the triggering component 3200 can sequentially pass through the locking detection element 3120, the judgment detection element 3130, and the unlocking detection element 3110 during rotation. Therefore, in the embodiment where the judgment detection element 3130 is provided, the method of using the lock may include the following steps:

[0098] First, the controller 4000 can control the drive unit 2200 to drive the knob 2100 to rotate to the second rotation position. Rotating the knob 2100 to the second rotation position locks the lock, as shown in Figure 11 or Figure 12. One of the locking triggers 3220 triggers the locking detection unit 3120, which sends a locking signal, causing the bolt 1200 to retract into the deadbolt 1000 and move to the locked position. The second rotation position, the locking signal, and the locked position are then associated. At this time, the controller 4000 can respond to the locking signal by acquiring the trigger signal from the judgment detection unit 3130, which includes the locking signal. Based on the trigger signal, it determines the rotation pattern of the knob 2100 and, based on the rotation pattern, determines the installation direction of the deadbolt 1000.

[0099] In one of the above embodiments, when the controller 4000 performs the aforementioned step of determining the rotation scheme of the knob 2100 based on the trigger signal and determining the installation direction of the deadbolt 1000 based on the rotation scheme, it may include the following steps: when the controller 4000 controls the knob 2100 to rotate to the second rotation position, as shown in FIG11, the unlocking trigger 3210 triggers the judgment detection element 3130. At this time, since the judgment detection element 3130 is triggered by the unlocking trigger 3210 in the manner shown in FIG11, the judgment detection element 3130 can issue a first judgment signal. The first judgment signal can determine that the trigger component 3200 is rotating on a fixed axis in a counterclockwise rotation manner as shown in FIG11. Therefore, when the controller 4000 obtains the first judgment signal, it can determine that the knob 2100 rotates in the first rotation scheme in the counterclockwise direction based on the first judgment signal, and then determine that the deadbolt 1000 is in the first installation direction based on the first rotation scheme.

[0100] Similarly, when the knob 2100 is rotated to the second rotation position, as shown in Figure 12, the unlocking trigger 3210 does not trigger the judgment detection element 3130. At this time, since the judgment detection element 3130 is not triggered by the unlocking trigger 3210 in the manner shown in Figure 12, the judgment detection element 3130 can issue a second judgment signal. This second judgment signal can determine that the trigger component 3200 is rotating on a fixed axis in a clockwise rotation manner as shown in Figure 12. Therefore, when the controller 4000 obtains the second judgment signal, it can determine that the knob 2100 rotates in the second clockwise direction according to the second judgment signal, and then determine that the deadbolt 1000 is in the second installation direction according to the second rotation scheme.

[0101] Therefore, the setting of the detection element 3130 can be used to determine the rotation direction of the knob 2100 and the trigger component 3200 during the detection process. That is, when the knob 2100 is rotated to the second rotation position, the detection element 3130 is triggered, resulting in a counterclockwise rotation as shown in Figure 11; when the detection element 3130 is not triggered, it rotates clockwise as shown in Figure 12. In the above detection process, the installation direction of the lock can be determined by the detection element 3130, adapting to different schemes of left-opening and right-opening doors. Therefore, during the installation and use of this lock, it can adapt to the installation direction of either the left-opening or right-opening door. That is, regardless of whether it is installed in the direction of the left-opening door or the direction of the right-opening door, the lock can be used normally. This effectively reduces the difficulty of lock installation and does not require restrictions on installation conditions, simplifying the lock installation and calibration process.

[0102] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0103] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
