The mounting base is installed on the door, and the first handle is rotatably connected to the mounting base. The clutch assembly is installed on the first handle and includes a clutch block, a transmission component, and a clutch actuator. The battery can power the clutch actuator, which can drive the transmission component to rotate. A spiral groove is formed inside the clutch block by a helical spring. When the clutch actuator drives the transmission component to rotate, the transmission component can slide along the spiral groove, so that the clutch block moves to a position connected or disconnected from the lock cylinder drive shaft. The lock cylinder drive shaft rotates synchronously with the lock cylinder's actuating component.

[0003] When the clutch is disengaged from the lock cylinder drive shaft, the first handle is in an idle state, and turning the first handle will not unlock the lock.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0040] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0041] Reference Figures 1 to 6 The electronic lock cylinder driving device of this utility model embodiment includes a mounting base 100, a first handle 200, a lock cylinder drive shaft 300, a clutch assembly 400, a storage battery 500, and an emergency lock cylinder 600. The first handle 200 is rotatably mounted on the mounting base 100 about a first axis A. The lock cylinder drive shaft 300 is rotatably mounted on the mounting base 100 about the first axis A. The clutch assembly 400 includes a clutch block 410, a first transmission block 420, and a clutch driver 430. The clutch block 410 is movably mounted on the first handle 200 along the first axis A. The clutch block 410 includes a clutch block body 411 and a coil spring 412. The coil spring 412 is connected to the clutch block body 411 and forms a first spiral groove 4121. The coil spring 412 is arranged along the direction of the first axis A. The first transmission block 420 is slidably mounted in the first spiral groove 4121. The clutch driver... Clutch actuator 430 is disposed on the first handle 200. The clutch actuator 430 has an output shaft 431 disposed along the direction of the first axis A. The output shaft 431 is connected to the first transmission block 420 and the two rotate synchronously. The clutch block 410 is opposite to the lock cylinder transmission shaft 300 along the first axis A. The clutch block 410 can move to a position connected or disconnected from the lock cylinder transmission shaft 300. When the clutch block 410 is connected to the lock cylinder transmission shaft 300, the clutch block 410 and the lock cylinder transmission shaft 300 rotate synchronously. The battery 500 is disposed on the first handle 200 and electrically connected to the clutch actuator 430. The emergency lock cylinder 600 is disposed on the first handle 200. The emergency lock cylinder 600 is provided with a keyhole 621 and a telescopic part. The telescopic part can extend and retract along the direction of the first axis A. The telescopic part can drive the clutch block 410 to move toward the lock cylinder transmission shaft 300. The emergency lock cylinder 600 can be driven by a key to extend and retract the telescopic part.

[0042] When the clutch block 410 is not connected to the lock cylinder drive shaft 300, the user will not be able to turn the first handle 200 to make the lock cylinder drive shaft 300 rotate, thus making it impossible to unlock.

[0043] The lock cylinder drive shaft 300 is connected to the lock cylinder's actuating element. Under normal conditions, the battery 500 can supply power to the clutch driver 430. The clutch driver 430 drives the first transmission block 420 to rotate via the output shaft 431. When the first transmission block 420 rotates, it can slide along the first spiral groove 4121, applying force to move the clutch block 410 along the first axis A, thereby enabling the clutch block 410 to connect or disconnect from the lock cylinder drive shaft 300. When the clutch block 410 is connected to the lock cylinder drive shaft 300, when the user rotates the first handle 200, the actuating element of the lock cylinder can be rotated through the clutch assembly 400 and the lock cylinder drive shaft 300, thereby opening the door lock.

[0044] When the battery 500 has insufficient power to drive the clutch actuator 430, the user can insert a key into the emergency lock cylinder 600. The key drives the telescopic part of the emergency lock cylinder 600 to extend or retract. The telescopic part of the emergency lock cylinder 600 can directly drive the clutch block 410 to move toward the lock cylinder drive shaft 300, so that the clutch block 410 is connected to the lock cylinder drive shaft 300. Then the user can turn the first handle 200. The first handle 200 drives the lock cylinder's actuating component to rotate through the clutch block 410 to perform the unlocking operation, which is more convenient to use and has a better emergency effect.

[0045] Specifically, the direction along the first axis A can refer to the direction parallel to the first axis A, or directly on the first axis A.

[0046] Specifically, the clutch actuator 430 is a motor that can output rotational power. It is understood that in other embodiments, the clutch actuator 430 may also be other structures that output rotational power, and those skilled in the art can choose according to actual needs.

[0047] Specifically, in this embodiment, the lock cylinder drive shaft 300 is provided with a square rod, which can be directly inserted into the actuating part of the lock cylinder for transmission. It is understood that in other embodiments, the lock cylinder drive shaft 300 may be provided with a non-circular rod, which is inserted into the actuating part of the lock cylinder for transmission.

[0048] In this embodiment, the emergency lock cylinder 600 includes a housing 610, a rotating shaft 620, a telescopic shaft 630, and a tumbler structure. The rotating shaft 620 is rotatably mounted on the housing 610, and the telescopic shaft 630 is telescopically mounted on the housing 610 along the direction of the first axis A. The telescopic shaft 630 has a telescopic portion. The rotating shaft 620 is provided with a second spiral groove 622, and the telescopic shaft 630 is provided with a second transmission block 631. The second transmission block 631 is slidably mounted on the second spiral groove 622. A keyhole 621 is provided on the rotating shaft 620, and the tumbler structure is provided between the housing 610 and the rotating shaft 620. The tumbler structure can lock or unlock the position of the rotating shaft 620 relative to the housing 610. When a key is inserted into the keyhole 621, the tumbler structure unlocks the position of the rotating shaft 620 relative to the housing 610.

[0049] When the key is not inserted, the pin tumbler structure locks the position of the rotating shaft 620 relative to the outer casing 610, and the emergency lock cylinder 600 is not in operation. When the key is inserted, it drives the pin tumbler structure to the unlocked state. At this time, the rotating shaft 620 can rotate relative to the outer casing 610. When the rotating shaft 620 rotates, it applies force to the second transmission block 631 through the second helical groove 622, causing the telescopic shaft 630 to move along the first axis A. This, in turn, pushes the clutch block 410 to move along the first axis A. The emergency lock cylinder 600 has a relatively simple structure and is easy to implement.

[0050] Specifically, the tumbler structure may include a movable pin and a drive spring. Both the rotating shaft 620 and the housing 610 are provided with pin holes. The movable pin is slidably disposed in the pin hole and can slide between the rotating shaft 620 and the housing 610. The drive spring is connected to the housing 610 and abuts against one end of the movable pin. In the normal state, the drive spring causes the movable pin to be inserted into both the pin hole of the rotating shaft 620 and the pin hole of the housing 610 simultaneously, at which time the position of the rotating shaft 620 is locked. When the key is inserted, the movable pin is pushed out of the pin hole of the rotating shaft 620 and fully enters the pin hole of the housing 610. At this time, the position of the rotating shaft 620 is unlocked and can be driven to rotate by the key, thereby causing the telescopic shaft 630 to extend and retract.

[0051] There are also some existing electronic lock cylinder drive devices with an emergency lock cylinder inside. However, the emergency lock cylinder is in rigid contact with the clutch assembly. If the first handle (200) is not rotated to reset accurately, the emergency lock cylinder may be damaged if it is used directly. Therefore, the following improvements are made.

[0052] In this embodiment, an elastic element 632 is provided at one end of the telescopic shaft 630 near the clutch block 410. The elastic element 632 forms a telescopic part, and the telescopic shaft 630 contacts the clutch block 410 through the elastic element 632. When the telescopic shaft 630 pushes the clutch block 410 towards the lock cylinder drive shaft 300, the elastic deformation of the elastic element 632 makes the change in the movement speed of the clutch block 410 smoother, avoiding the risk of the clutch block 410 being damaged by collision due to rigid contact between the telescopic shaft 630 and the clutch block 410, and reducing the risk of damage to the clutch block 410 and the lock cylinder drive shaft 300 when the first handle 200 is not accurately reset and the lock is opened by the emergency lock cylinder 600.

[0053] Specifically, the elastic element 632 is a spring. It is conceivable that in other embodiments, the elastic element 632 may also be an elastic component such as a rubber block or a silicone block, which can be selected by those skilled in the art according to actual needs.

[0054] Specifically, the telescopic shaft 630 is provided with a recessed hole, and the elastic element 632 is partially embedded in the recessed hole, which avoids the risk of the elastic element 632 being misaligned when compressed, and ensures relatively accurate installation and positioning of the elastic element 632.

[0055] In this embodiment, the rotating shaft 620 is provided with a receiving hole 623, the telescopic shaft 630 is located in the receiving hole 623, the second spiral groove 622 is provided on the wall of the receiving hole 623, the second transmission block 631 passes through the second spiral groove 622, and the outer shell 610 is provided with a guide groove 611 along the direction of the first axis A. One end of the second transmission block 631 is slidably connected to the guide groove 611. The second transmission block 631 is slidably connected to both the second spiral groove 622 and the guide groove 611. The guide groove 611 can guide the telescopic shaft 630 through the second transmission block 631, so that the telescopic shaft 630 can only slide along the direction of the first axis A. The second spiral groove 622 can cooperate with the second transmission block 631, so that when the rotating shaft 620 rotates, it can abut against the second transmission block 631 through the groove wall of the second spiral groove 622, thereby driving the telescopic shaft 630 to move along the direction of the first axis A. The emergency lock cylinder 600 has a relatively compact structure and good performance.

[0056] In this embodiment, the first handle 200 includes a handle body 210 and a first cover plate 220. The handle body 210 is provided with a battery mounting hole 211 and a lock cylinder mounting hole 212. A storage battery 500 is disposed in the battery mounting hole 211, and an emergency lock cylinder 600 is disposed in the lock cylinder mounting hole 212. The first cover plate 220 is detachably disposed on the handle body 210 and covers the openings of the battery mounting hole 211 and the lock cylinder mounting hole 212. The keyhole 621 of the emergency lock cylinder 600 is opposite to the first cover plate 220. By using a single first cover plate 220 to simultaneously cover both the storage battery 500 and the emergency lock cylinder 600, the structure is simpler and manufacturing costs are reduced compared to the previous method of using two covers to separately cover the battery mounting hole 211 and the lock cylinder mounting hole 212.

[0057] Specifically, the first cover plate 220 is detachably connected to the handle body 210 by means of screws. It is conceivable that in other embodiments, the first cover plate 220 may also be detachably connected to the handle body 210 by means of, for example, snap-fit ​​or magnetic engagement.

[0058] Furthermore, the first handle 200 also includes a second cover plate 230, which is pivotally connected to the handle body 210 and can rotate to a position that avoids or covers the first cover plate 220. The second cover plate 230 can rotate to a position that covers the first cover plate 220, thereby concealing the first cover plate 220 and improving its concealment; when the second cover plate 230 is rotated to a position that avoids the first cover plate 220, it is convenient for the user to remove the first cover plate 220 with a screwdriver to use the emergency lock cylinder 600.

[0059] In this embodiment, the lock cylinder drive shaft 300, clutch assembly 400 and emergency lock cylinder 600 are all located on the first axis A. The clutch assembly 400 is located between the lock cylinder drive shaft 300 and the emergency lock cylinder 600, which allows the layout of the clutch assembly 400 and the emergency lock cylinder 600 to be relatively compact, without requiring the first handle 200 to be large, which is beneficial to the miniaturization requirement.

[0060] Furthermore, the rotating shaft 620 and telescopic shaft 630 of the emergency lock cylinder 600 are also located on the first axis A, and the output shaft 431 is also located on the first axis A, which is conducive to the miniaturization of the structure of the first handle 200 and the relatively compact layout.

[0061] In this embodiment, the clutch block body 411 includes a clutch head 4111, a first mounting member 4112, and a second mounting member 4113. The first mounting member 4112 and the second mounting member 4113 are arranged around the output shaft 431. A spring mounting cavity 4114 and a pin limiting groove 4115 are formed between the first mounting member 4112 and the second mounting member 4113. The pin limiting groove 4115 communicates with the spring mounting cavity 4114 and is located along the first axis A. Extending inward, the helical spring 412 includes a helical portion 4122 and pin portions 4123 located at both ends of the helical portion 4122. The helical portion 4122 is located in the mounting cavity, and both pin portions 4123 are located in the pin limiting groove 4115. The output shaft 431 passes through the spring mounting cavity 4114. The clutch head 4111 is located at one end of the clutch block 410 near the lock cylinder drive shaft 300. The clutch head 4111 is engaged with the first mounting member 4112 and the second mounting member 4113.

[0062] The aforementioned clutch block body 411 restricts the position of the pin portion 4123 via the pin limiting groove 4115, preventing the coil spring 412 from rotating relative to the clutch block body 411. Furthermore, the spring mounting cavity 4114 restricts the position of the helical portion 4122, facilitating the first transmission block 420 to apply force through the helical portion 4122 of the coil spring 412, thus moving the clutch block 410. The structure is simple and easy to implement. The clutch head 4111 engages with one end of the first mounting member 4112 and one end of the second mounting member 4113, allowing the clutch head 4111 to assemble and fix the first mounting member 4112 and the second mounting member 4113 without the need for screws. Moreover, the clutch head 4111 can be selected to a suitable size according to the specifications of the lock cylinder transmission shaft 300, offering greater versatility.

[0063] Specifically, using a helical spring 412 to form the first helical groove 4121 avoids rigid transmission between the clutch block 410 and the first transmission block 420, making the movement of the clutch block 410 smoother and reducing the risk of the clutch block 410 being damaged by collision. Furthermore, the helical spring 412 forming the first helical groove 4121 eliminates the need to manufacture a relatively complex helical groove on the clutch block 410, simplifying the production process and saving production costs. Moreover, when the first helical groove 4121 wears out, it is only necessary to disassemble the clutch block 410 and replace the helical spring 412 to restore the function of the clutch block 410, which is convenient for maintenance and extends its service life.

[0064] In this embodiment, one end of the lock cylinder drive shaft 300 is provided with a insertion hole 310, which can be inserted into the end of the clutch block 410 near the lock cylinder drive shaft 300. The insertion hole 310 is a non-circular hole. When the clutch block 410 is inserted into the insertion hole 310 of the lock cylinder drive shaft 300, because the insertion hole 310 is a non-circular hole, the lock cylinder drive shaft 300 and the clutch block 410 can rotate synchronously to perform the unlocking operation. The structure is relatively simple and relatively convenient to use. It is conceivable that in some other embodiments, the insertion hole 310 can also be provided in the clutch block 410, and one end of the lock cylinder drive shaft 300 can be adapted to the insertion hole 310.

[0065] Specifically, the insertion hole 310 is a cross-shaped hole, and the clutch block 410 has a straight cross-section, so that the clutch block 410 and the insertion hole 310 can be inserted and engaged at two different angle positions.

[0066] In one embodiment, the first handle 200 has a guide hole 213 along the first axis A. The clutch block 410 is slidably connected to the guide hole 213, and both the first mounting member 4112 and the second mounting member 4113 abut against the wall of the guide hole 213. While the clutch block 410 is slidably connected to the guide hole 213, the first mounting member 4112 and the second mounting member 4113 are located within the guide hole 213, allowing the wall of the guide hole 213 to clamp the first mounting member 4112 and the second mounting member 4113, maintaining their connection. This ensures that the first mounting member 4112 and the second mounting member 4113 can have good assembly stability without the need for screw fastening. It is conceivable that in other embodiments, the clutch block 410 can also slide relative to the first handle 200 through a guide post and guide sleeve structure.

[0067] In this embodiment, a second handle 700 is also included, rotatably mounted on the mounting base 100 about the first axis A. The first handle 200 and the second handle 700 are respectively located at both ends of the lock cylinder drive shaft 300. The second handle 700 is connected to the lock cylinder drive shaft 300, and the two rotate synchronously. Specifically, the first handle 200 is located outside the door, and the second handle 700 is located inside the door.
