Referring to FIGS. 1 to 5, a lock with multiple switchable operating modes according to an embodiment of the present disclosure has a first operating mode and a second operating mode, and comprises: a front lock body 100; a rear lock body 200; a connecting rod 300, wherein one end of the connecting rod is connected to the rear lock body 200, and the other end of the connecting rod is fixedly connected to a driving member 310 extending into the front lock body 100; an electric clutch mechanism 400 arranged on the front lock body 100, wherein the electric clutch mechanism 400 has a first clutch member 410 that is capable of being engaged with or separated from the driving member 310; a mechanical lock cylinder 500 arranged on the front lock body 100, wherein the mechanical lock cylinder 500 has a second clutch member 600 that is capable of being engaged with or separated from the driving member 310; an identification module arranged on the front lock body 100 and electrically connected to the electric clutch mechanism 400; a first switch member 710 arranged on the front lock body 100; a blocking member 720 movably arranged on the front lock body 100; a first linkage mechanism 800, wherein the first linkage mechanism 800 comprises an operating member 810 arranged on the rear lock body 200, a moving member 820 arranged on the front lock body 100, and a linkage member 830 arranged between the operating member 810 and the moving member 820, the moving member 820 has a first operating position and a second operating position, the operating member 810 is capable of driving the moving member 820 to switch between the first operating position and the second operating position through the linkage member 830, the moving member 820 located at the first operating position is capable of triggering the first switch member 710, so that the first switch member 710 generates a trigger signal, and the moving member 820 located at the second operating position is capable of driving the blocking member 720 to move so as to prevent the first clutch member 410 and the driving member 310 from being engaged to enable the lock to be switched to the second operating mode; and a control module, wherein the control module is electrically connected to the identification module, the electric clutch mechanism 400 and the first switch member 710, and controls the lock to be switched to the first operating mode according to the trigger signal.

The lock with the above structure can be switched to a first operating mode or a second operating mode by using the first linkage mechanism 800. In the first operating mode, the moving member 820 is capable of triggering the first switch member 710, so that the control module can control the electric clutch mechanism 400 to work only when receiving specific identification information, thereby limiting a condition that the lock can be opened. In the second operating mode, the moving member 820 is capable of driving the blocking member 720 to move so as to prevent the first clutch member 410 and the driving member 310 from being engaged, in this case, entering any identification information cannot achieve electric unlocking, any identification information input cannot achieve electric unlocking, and the mechanical lock cylinder 500 can only be unlocked using a key. With the above structure, a user can adjust the lock to the first operating mode or the second operating mode according to the required privacy degree to meet the needs of different usage scenarios and expand the functions of the lock.

It may be understood that, specifically, when a user in a room is not expected to the disturbance of others outside the room other than a designated person, the lock is adjusted to the first operating mode. In this case, the others other than the designated person cannot start the electric clutch mechanism 400 even if inputting ordinary authentication information. However, the authentication information of the designated person can start the electric clutch mechanism 400 to unlock the lock. For example, when a child enters a room and drives the operating member 810, the operating member 810 drives the moving member 820 to move to the first operating position through the linkage member 830, in this case, the moving member 820 triggers the first switch member 710, the first switch member 710 generates a trigger signal, and the control module adjusts the authentication information that can be identified by the identification module according to the trigger signal, so that other people other than parents cannot unlock through the electric clutch mechanism 400. For another example, when one or more users enter a room and perform a related privacy action, to obtain a use function with a higher privacy degree, the user may drive the operating member 810 to move the moving member 820 to the second operating position. In this case, the moving member 820 is capable of driving the blocking member 720 to move to a position where the first clutch member 410 and the driving member 310 are prevented from being engaged, so that the electric clutch mechanism 400 fails, and a person located outside the room door can only open the mechanical lock cylinder 500 by using a key to unlock, which not only achieves a better privacy protection effect, but also retains the function of unlocking, thereby ensuring security.

In some embodiments of the present disclosure, when the lock is in the first operating mode, the identification module receives an administrator password and can trigger the control module to drive the first clutch member 410 and the driving member 310 to be engaged; and when the lock is in the second operating mode, a user can only insert a key into the mechanical lock cylinder 500 to engage the second clutch member 600 with the driving member 310. It should be noted that the administrator password may be at least one of a designated digital password, a fingerprint password, and face information. When the operating member 810 is in an initial position, the lock is in other operating modes other than the first operating mode and the second operating mode, in this case, the lock can be unlocked by any preset password information. In a case that the lock is in the first operating mode, if and only when the identification module receives the administrator password, the control module can control the electric clutch mechanism 400 to act so as to achieve electric unlocking, thereby achieving a certain degree of privacy guarantee. When the user requires a higher level of privacy guarantee, the user drives the first linkage mechanism 800 to move the blocking member 720 to prevent the first clutch member 410 and the driving member 310 from being engaged. In this case, even if the first clutch member 410 tends to move toward the driving member 310, the first clutch member 410 cannot be engaged with the driving member 310 under the blocking of the blocking member 720.

Referring to FIGS. 2, 3, and 4, in some embodiments of the present disclosure, a through hole 320 is formed in the connecting rod 300 and extends through the connecting rod along a length direction of the connecting rod, the linkage member 830 is a rod member that extends through the through hole 320, the operating member 810 is connected to one end of the rod member close to the rear lock body 200 and protruding out of an outer surface of the rear lock body 200, the moving member 820 is connected to one end of the rod member close to the front lock body 100 and protruding out of the driving member 310, the moving member 820 has a first eccentric portion 821 that protrudes out along a side portion of the rod member, and the operating member 810 is capable of driving the rod member and the moving member 820 to rotate together around a first axis relative to the connecting rod 300, so that the first eccentric portion 821 can contact the first switch member 710 or the blocking member 720. It may be understood that the operating member 810 is a knob member. When the operating member 810 rotates, the rod member and the moving member 820 are driven to rotate together, and in this case, the first eccentric portion 821 on the moving member 820 is capable of triggering the first switch member 710 or is capable of driving the blocking member 720 to move to a position where the first clutch member 410 can be blocked from moving toward the driving member 310. In this embodiment, the first switch member 710 and the blocking member 720 are respectively located at two opposite sides of the moving member 820, and rotating the operating member 810 clockwise and rotating the operating member 810 counterclockwise correspond to the first operating position and the second operating position of the moving member 820, respectively. The first linkage mechanism 800 is simple in structure and operation, and compared with a conventional mode of implementing back-locking by using a spring bolt, the first linkage mechanism has more functions and more application scenarios. Moreover, it should be noted that the connecting rod 300 in the existing technology is a solid rod. However, the lock of the present disclosure is skillfully provided with a through hole 320 inside the connecting rod 300, the linkage member 830 extends through the through hole 320, and the first eccentric portion 821 of the moving member 820 is linked to rotate in a rotating manner to trigger the first switch member 710 or drive the blocking member 720 to prevent the first clutch member 410 and the driving member 310 from being engaged, so that this structure is highly compact and does not change a basic structure of the original lock, which has a positive influence on the manufacturing of lock.

Referring to FIG. 5, in some embodiments of the present disclosure, the blocking member 720 is rotatably arranged on the front lock body 100 through a first pivot 721, one end of the blocking member 720 corresponds to the moving member 820, the other end of the blocking member 720 can rotate to abut against the first clutch member 410 to prevent the first clutch member 410 and the driving member 310 from being engaged, the blocking member 720 is connected to a first elastic member 722, and the first elastic member 722 drives the blocking member 720 away from the first clutch member 410 to enable the first clutch member 410 to be engaged with the driving member 310. It should be noted that when the first eccentric portion 821 of the moving member 820 does not contact the blocking member 720, the blocking member 720 is far away from the first clutch member 410 under the action of the first elastic member 722 to avoid blocking the first clutch member 410 and the driving member 310 from being engaged, and when the moving member 820 rotates such that the first eccentric portion 821 drives the blocking member 720 to rotate around the first pivot 721, one end of the blocking member 720 far away from the first eccentric portion 821 rotates to prevent the first clutch member 410 from extending toward the driving member 310.

It may be understood that the structure of the first linkage mechanism 800 is not limited to the above form, and the movement manner of the operating member 810, the linkage member 830 and the moving member 820 is not limited to rotation. Here, the applicant proposes another implementation for the first linkage mechanism 800. Referring to FIG. 6, the first linkage mechanism 800 comprises a rod member, wherein one end of the rod member is connected to the pressing member, the other end of the rod member is connected to the push block, and a pressing and positioning structure is provided between the pressing member and the rear lock body 200.

Specifically, the pressing and positioning structure comprises an elastic clamping block 811 arranged on the pressing member, a guide rail 210 is arranged in the rear lock body 200 and is configured to allow the elastic clamping block 811 to rotate, the guide rail 210 is provided with a first positioning groove 220 and a second positioning groove 230 at an interval in a pressing direction of the pressing member, the first positioning groove 220 has a first guide inclined surface 221 for guiding the elastic clamping block 811 to leave the first positioning groove 220 to enter the second positioning groove 230, the second positioning groove 230 has a second guide inclined surface 231 for guiding the elastic clamping block 811 to leave the second positioning groove 230 to return to the guide rail 210, and two opposite sides of the push block are provided with a first side push inclined surface 823 and a second side push inclined surface 824. When the pressing member is pushed forward for a specific distance, the elastic clamping block 811 enters the first positioning groove 220, in this case, the first guide inclined surface 221 abuts against the first switch member 710, the lock is switched to the first operating mode. When the pressing member is pushed forward for a specific distance again, the elastic clamping block 811 leaves the first positioning groove 220 along the first guide inclined surface 221 to enter the second positioning groove 230, in this case, the second guide inclined surface 231 abuts against the blocking member 720 to enable the blocking member 720 to move to a position where the first clutch member 410 can be blocked from moving toward the driving member 310, so as to prevent the first clutch member 410 and the driving member 310 from being engaged. When the pressing member is pushed forward for a specific distance again, the elastic clamping block 811 leaves the second positioning groove 230 along the second guide inclined surface 231 to return to the guide rail 210, and the pressing member is connected to a spring member that drives the return movement of the pressing member, so that the pressing member can retreat back to an original position. The first linkage mechanism 800 can also achieve the switching of the operating modes of the lock by using a pressing mode.

Referring to FIGS. 3 and 4, in some embodiments of the present disclosure, the rod member is a strip, the strip is freely rotatable in the through hole 320, the operating member 810 is provided with a first slot 812 for one end of the strip to be inserted, the other end of the strip is provided with a T-shaped anti-disengaging portion 831, the moving member 820 is provided with a second slot 822 matched with the T-shaped anti-disengaging portion 831, and a clamp 840 for driving the T-shaped anti-disengaging portion 831 to be tightly engaged with the second slot 822 is arranged outside the moving member 820. It may be understood that, in general, the operating member 810 and the moving member 820 are made of plastic material, the strip is made of metal material, and one end of the strip is inserted into the first slot 812 to form a tight engaging effect, so as to simplify a connection structure between the operating member 810 and the rod member without screwing or glue for fixing. Since the moving member 820 is located inside the front lock body 100, if the moving member 820 falls off the strip, it will cause the remaining parts inside the front lock body 100 to be locked. The other end of the strip is provided with a T-shaped anti-disengaging portion 831, and the T-shaped anti-disengaging portion 831 extends through the second slot 822 to facilitate the simplification of a connection structure between the moving member 820 and the rod member without screwing or glue for fixing. Moreover, the clamp 840 is configured to drive the T-shaped anti-disengaging portion 831 and the second slot 822 to be tightly engaged with each other, so that the shifting of the moving member 820 relative to the rod member can be prevented.

It should be noted that, when the lock is in the second operating mode, the electric clutch mechanism 400 cannot be electrically unlocked, in this case, people outside the room can still unlock the lock by using the key, and if people inside the room are engaging in a relatively private behavior, to ensure that this behavior is not disturbed, when the key is inserted into the keyhole 510, the sensing part detects the existence of the key and transmits information to the control module, and the control module controls the linear driver 530 to drive the pre-ejecting member 520 to extend out, so that the key is prevented from being completely inserted into the keyhole 510 to unlock the lock, and meanwhile, the alarm module is started, and people inside the room can approve or refuse people outside the room to use the key to unlock the lock through a voice instruction. Specifically, when the user agrees with the unlocking by the voice instruction, the alarm module is stopped, the linear driver 530 drives the pre-ejecting member 520 to be retracted, and the key can be completely inserted into the keyhole 510, and when the user refuses the unlocking by the voice instruction, the alarm module is stopped, the linear driver 530 drives the pre-ejecting member 520 to be kept extended out, and the key cannot be completely inserted into the keyhole 510. The linear driver 530 may be an electric push rod.

Referring to FIG. 7, in some embodiments of the present disclosure, the electric clutch mechanism 400 comprises a motor 420 fixedly arranged in the front lock body 100, a rotation block 430 connected to an output shaft of the motor 420, and a moving block 440 that is capable of reciprocating along an extending direction of the output shaft of the motor 420, the second clutch member 600 is a second plug pin arranged on the moving block 440, the driving member 310 is provided with a second plug hole corresponding to the second plug pin, a magnetic component 450 is arranged between the rotation block 430 and the moving block 440, and when the motor 420 drives the rotation block 430 to rotate, the magnetic component 450 drives the moving block 440 close to or away from the rotation block 430, so as to drive the second plug pin to insert into or separate from the second plug hole. Specifically, the rotation block 430 and the moving block 440 are circumferentially provided with a first magnet 451 and a second magnet 452 around the output shaft of the motor 420, the magnetic poles of ends of the first magnet 451 and the second magnet 452 close to each other are opposite, and two first magnets 451 and two second magnets 452 jointly form the magnetic component 450.
