One of the second unlocking module 750 and the first unlocking module 730 is a password unlocking module and the other is an electronic unlocking module. The electronic unlocking module is electrically connected to the control circuit board 710. When the electric clutch 200 is in the closed state, the handle 300 can drive the locking tongue 600 to move through the electric clutch 200 to unlock or lock. When the electric clutch 200 is in the open state, the handle 300 cannot drive the locking tongue 600 to move through the electric clutch 200.

[0029] Reference Figure 1 and Figure 3 The control circuit board 710 is installed inside the handle 300, the first unlocking module 730 is located on the outer periphery of the handle 300, the key unlocking module 740 is located on the end face of the handle 300 opposite to the lock seat 100, and a cover 400 is movably installed on the end face of the handle 300 opposite to the lock seat 100. The second unlocking module 750 is installed on the cover 400 and electrically connected to the control circuit board 710. The cover 400 can be moved to avoid or cover the key unlocking module 740. Thus, through reasonable layout and the addition of the cover 400, the various modules of the unlocking system are successfully integrated into the space-constrained handle 300, thereby eliminating the need to add a panel to the lock seat 100 or increase the volume of the lock seat 100, effectively controlling the volume of the lock seat 100, and making the electric clutch lock structure more compact.

[0030] The handle 300 and the locking tongue 600 are connected by an electric clutch 200. The electric clutch 200 only needs to be installed in the mounting hole 120 on the lock seat 100. In the specific implementation, the electric clutch 200 can be designed to be relatively compact and small. As a result, the size of the lock seat 100 can be further controlled, making the electric clutch lock structure more compact.

[0031] In practical implementation, the lock seat 100 of the electric clutch lock is installed on the door body, and the handle 300 is on the outside of the door body and faces the door body. The handle 300 is within the rotation range of the door body. Therefore, the door body only needs to meet the installation requirements of the lock seat 100, and the electric clutch lock requires little installation space.

[0032] Through the above-described configuration, the electric clutch lock provided by this utility model can effectively integrate the control circuit board 710, the first unlocking module 730, the key unlocking module 740, and the second unlocking module 750 of the unlocking system onto the handle 300. The handle 300 and the lock tongue 600 are connected by an electric clutch 200, which only needs to be installed in the mounting hole 120 on the lock seat 100. Thus, the electric clutch lock provided by this utility model has multiple unlocking functions and can also effectively control the volume of the lock seat 100, thereby making the overall structure of the electric clutch lock more compact, requiring less installation space, and better meeting the needs of use in places with limited installation space, such as wardrobes and cabinets.

[0033] Of course, the electric clutch lock provided by this utility model can also meet the needs of bedroom doors, hall doors and other occasions.

[0034] Reference Figure 1 and Figure 2 In some embodiments, the main body 100a of the lock seat 100 is cylindrical, and an external thread 110 is provided on the outer periphery of the main body 100a. A mounting hole 120 is axially arranged along the main body 100a of the lock seat 100, and the mounting hole 120 is eccentric to the main body 100a of the lock seat 100. According to the illustrated embodiment, the outer diameter of the main body 100a of the lock seat 100 can be as small as 1.25 inches, requiring minimal installation space. Of course, in the specific implementation process, the outer diameter of the main body 100a of the lock seat 100 can also be increased or decreased according to actual needs: if the outer diameter of the main body 100a of the lock seat 100 is reduced, for example, if the outer diameter of the main body 100a of the lock seat 100 needs to be made to 1 inch, the eccentric distance of the mounting hole 120 can be reduced to keep the size of the mounting hole 120 unchanged; if the outer diameter of the main body 100a of the lock seat 100 is increased, for example, if the outer diameter of the locking main body 100a needs to be made to 2 inches, the eccentric distance of the mounting hole 120 can be increased to keep the size of the mounting hole 120 unchanged.

[0035] According to the illustrated embodiment, the outer diameter of the handle 300 can be 45mm. Of course, in other embodiments, the outer diameter of the handle 300 can be increased or decreased according to actual needs, for example, the outer diameter of the handle 300 can be set to 40mm or 50mm.

[0036] In some embodiments, the unlocking system may further include a battery 720, which is electrically connected to a control circuit board 710, thereby allowing the control circuit board 710 to be powered by the battery 720.

[0037] Of course, in some other embodiments, the control circuit board 710 may also be powered by the mains or a wireless power supply device, in which case the battery 720 mentioned above may not be required.

[0038] According to some embodiments of the present invention, the unlocking system also includes a data interface, which is located on the end face of the handle 300 away from the lock seat 100. The cover 400 is movable to avoid or cover the data interface. The data interface can be a USB interface, a Type-C interface or other types of interface. Mobile phones, computers and other terminals can be connected to the data interface through data cables, and then these terminals can send unlocking signals or locking signals to the control circuit board 710.

[0039] Reference Figures 1 to 3 According to some embodiments of this utility model, the handle 300 includes a housing 300a and a mounting base 300b. The housing 300a has an opening 310 on its side opposite to the lock seat 100. The mounting base 300b is installed on the housing 300a through the opening 310. The key unlocking module 740 and the control circuit board 710 are fixedly installed on the mounting base 300b and located inside the housing 300a. During installation, the key unlocking module 740 and the control circuit board 710 can be installed onto the mounting base 300b first, and then the mounting base 300b can be installed into the housing 300a, making installation convenient and simple. The mounting base 300b can support the housing 300a, thereby improving the overall strength of the handle 300.

[0040] Reference Figures 1 to 3 According to some embodiments of this utility model, the outer shell 300a is connected to one end of the electric clutch 200. A threaded fastener 300c is installed on the side of the outer shell 300a facing the lock seat 100. The threaded fastener 300c is screwed to the mounting base 300b, wherein the length of the threaded fastener 300c is greater than the distance between the outer shell 300a and the lock seat 100. During the assembly process, the outer shell 300a and the mounting base 300b are assembled together first, and then the outer shell 300a is assembled with the electric clutch 200. After the electric clutch lock is assembled, the lock seat 100 can prevent people from disassembling the threaded fastener 300c between the mounting base 300b and the outer shell 300a, thereby preventing the mounting base 300b from being forcibly removed from the outer shell 300a, and thus preventing others from disassembling the control circuit board 710 and the key unlocking module 740, achieving anti-pry and anti-theft effects.

[0041] Reference Figures 1 to 3According to some embodiments of this utility model, the cover 400 is movably mounted on the end face of the mounting base 300b opposite to the lock base 100. The end face of the mounting base 300b opposite to the lock base 100 has an insertion hole 330 into which the battery 720 is inserted. A cover 500 is detachably mounted on the end face of the mounting base 300b opposite to the lock base 100, covering the insertion hole 330. Therefore, after opening the cover 400 and removing the cover 500, the battery 720 can be removed for replacement. Since the battery 720 replacement is also performed on the end face of the mounting base 300b opposite to the lock base 100, there is no need to provide other structures for battery replacement on the handle 300, thus avoiding a reduction in the strength of the handle 300.

[0042] Reference Figure 1 According to some embodiments of the present invention, the mounting base 300b and the outer shell 300a enclose to form a mounting groove 340, and the control circuit board 710 is located in the mounting groove 340. Thus, the control circuit board 710 can be protected to ensure the safety performance of the lock.

[0043] Reference Figure 1 and Figure 3 According to some embodiments of the present invention, the first unlocking module 730 is a password unlocking module. The password unlocking module includes a keyboard 730a electrically connected to the control circuit board 710. The keyboard 730a is installed on the housing 300a and is disposed opposite to the control circuit board 710. Thus, the electrical connection distance between the password unlocking module and the control circuit board 710 can be reduced.

[0044] Reference Figure 1 and Figure 3 In some embodiments, the outer casing 300a is provided with a window 320 opposite to the mounting groove 340, and the window 320 communicates with the mounting groove 340. The keyboard 730a is installed in the window 320, and an anti-pry protrusion 731 is provided between the keyboard 730a and the side wall of the window 320 to prevent the keyboard 730a from being removed from the window 320, thus ensuring the security performance of the lock. During assembly, the keyboard 730a can be installed in the window 320, the control circuit board 710 can be installed on the mounting base 300b, and then the mounting base 300b can be installed into the outer casing 300a.

[0045] Of course, in other embodiments, the keyboard 730a can also adopt other configuration methods. For example, multiple clearance holes can be provided in the housing 300a, the keyboard 730a is installed inside the housing 300a, and the multiple keys on the keyboard 730a are inserted into the multiple clearance holes one by one.

[0046] It should be noted that in some other embodiments, the password unlocking module can also be set as a mechanical password disk. The mechanical password disk is in transmission cooperation with the electric clutch 200. When the password entered by the mechanical password disk is correct, the mechanical password disk drives the electric clutch 200 to close.

[0047] Reference Figure 1 and Figure 4 According to some embodiments of this utility model, the electric clutch 200 includes a clutch housing 210, a first clutch element 220, a second clutch element 230, a motor 240, and a first push rod 250. The clutch housing 210 is rotatably mounted in the mounting hole 120. The handle 300 is fixedly connected to the clutch housing 210. The motor 240 is installed inside the clutch housing 210. The first clutch element 220 is rotatably mounted in the mounting hole 120 and located on the side of the clutch housing 210 opposite to the handle 300. The first clutch element 220 is fixedly connected to the locking tongue 600. The second clutch element 230 and the first push rod 250 are slidably mounted inside the clutch housing 210. The electric clutch 200 is connected to the second clutch 230 and driven by the motor 240. The motor 240 drives the first push rod 250 to slide the second clutch 230, so that the second clutch 230 is engaged with or disengaged from the first clutch 220. When the first clutch 220 and the second clutch 230 are engaged, the electric clutch 200 is in the engaged state. At this time, the handle 300 can drive the locking tongue 600 to rotate through the electric clutch 200 to unlock or lock. When the second clutch 230 is disengaged from the first clutch 220, the electric clutch 200 is in the disengaged state. At this time, the handle 300 cannot drive the locking tongue 600 to rotate. With the above configuration, the electric clutch 200 has a compact structure, which is beneficial to controlling the size of the electric clutch 200 and realizing the miniaturization of the electric clutch 200.

[0048] It should be noted that the electric clutch 200 described above can also be configured in other ways. For example, an electromagnetic push rod can be used to replace the motor 240 and the first push rod 250.

[0049] Reference Figure 1 and Figure 4According to some embodiments of this utility model, the electric clutch 200 further includes a second push rod 270 and a reset structure 260. The second push rod 270 is slidably installed inside the clutch housing 210. The second push rod 270 is in transmission cooperation with the key unlocking module 740. The key unlocking module 740 can drive the second push rod 270 to slide the second clutch member 230 so that the first clutch member 220 and the second clutch member 230 are engaged. The reset structure 260 can drive the second push rod 270 to move the second clutch member 230 away from the first clutch member 220. Thus, when the control circuit board 710 fails, the electric clutch 200 can be engaged by operating the key unlocking module 740 with the key, and then the handle 300 can be turned to unlock, realizing the function of emergency key unlocking.

[0050] The reset structure 260 is configured as a spring, which is sleeved on the output shaft of the motor 240. A helical drive part 241 is provided on the output shaft of the motor 240, and the helical drive part 241 is in drive engagement with the spring. Both ends of the spring abut against the first push rod 250, and the spring abuts against the second push rod 270. Therefore, when the output shaft of the motor 240 rotates, the helical drive part 241 can drive the spring to slide, thereby pushing the first push rod 250 to slide. When the second push rod 270 slides towards the first clutch member 220, it can compress the spring, thereby driving the second push rod 270 to reset. Thus, the spring can realize the drive connection between the first push rod 250 and the motor 240, and also realize the reset function of the second push rod 270. Through the above configuration, the structure of the electric clutch 200 can be made more compact.

[0051] It is conceivable that the aforementioned reset structure 260 can also be configured in other ways. For example, the reset structure 260 can be configured as a magnet, and the first push rod 250 and the second push rod 270 can be made of magnetic material. The magnet can generate an attractive force on the first push rod 250 and the second push rod 270 to pull the first push rod 250 and the second push rod 270 away from the first clutch 220.

[0052] Of course, in other embodiments, a switch can also be provided on the control circuit board 710. The key unlocking module 740 cooperates with the switch. When the key unlocking module 740 is operated by the key, the key unlocking module 740 can trigger the switch, thereby controlling the control circuit board 710 to control the electric clutch 200 to close.

[0053] In some embodiments, the key unlocking module 740 includes a lock cylinder, wherein the lock cylinder is a commonly used component in the art, and its specific structure will not be described in detail here.

[0054] According to some embodiments of this utility model, the electronic unlocking module is set as a fingerprint recognition module to realize fingerprint recognition unlocking.

[0055] Of course, in other embodiments, the electronic unlocking module can also be configured as an NFC recognition module, an iris recognition module, a wireless signal receiving module, or other electronic components to identify human characteristics or receive wireless unlocking signals.

[0056] 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.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
