  • the internal locking sleeve 114 is sleeved at the outer periphery of the internal locking lever 113, and an outer end of the internal locking sleeve 114 is connected to the thumb turn 12 and co-rotate with the latter.
  • the transmission clutch assembly 101 comprises a clutch transmission wheel 14, a slipping collar 15, and a shift fork 16.
  • the clutch transmission wheel 14 is axially located at the inner end of the internal locking lever 113 and co-rotates with the latter.
  • the slipping collar 15 is in sliding connection with the inner end of the internal locking sleeve 114 and is peripherally limited by the latter, i.e., the slipping collar 15 is axially slidable along the internal locking sleeve 114 and maintains synchronous rotation with the internal locking sleeve 114.
  • the slipping collar 15 maintains transmitting connection with the second mechanical unlocking assembly 202 and under the action of the second mechanical unlocking assembly 202, maintains separated from the clutch transmission wheel 14.
  • the shift fork 16 comprises a driven end 161, a connecting portion 162, and a fork body 163, the driven end 161 being connected to the electric actuator 201, the connecting portion 162 being rotatably connected to the fitting base 18, the fork body 163 extending till the outer end side of the slipping collar 15.
  • the inner wall of the accommodation groove 29 is provided with a notch 294 for avoiding the driven end 161.
  • the electric actuator 201 drives the driven end 161 so that the fork body 163 abuts against the slipping collar 15, allowing for fitting between the slipping collar 15 and the clutch transmission wheel 14 for transmission purpose, whereby the internal locking lever 113 may drive, sequentially via the clutch transmission wheel 14, the slipping collar 15, and the internal locking sleeve 114, the thumb turn 12 to enable unlocking.
  • a plug pin 151 is provided for the slipping collar 15, and a socket 141 is provided on an end surface of the clutch transmission wheel 14, so that when the slipping collar 15 is engaged with the clutch transmission wheel 14, the plug pin 151 is insert-fitted in the socket 141, as illustrated in Fig. 9 .
  • the slipping collar 15 is driven to rotate; the first mechanical unlocking assembly 102 may drive, sequentially via the exterior cylinder core 13, the internal locking lever 113, the clutch transmission wheel 14, the slipping collar 15, and the internal locking sleeve 114, the thumb turn 12 to enable unlocking.
  • the plug pin 151 departs from the socket 141, in which case the clutch transmission wheel 14 cannot transmit a torque to the slipping collar 15, so that the internal locking lever 113 cannot drive the internal locking sleeve 114 to move; hence, unlocking is disabled, and the first mechanical unlocking assembly 102 only rotates idly.
  • the interior cylinder core 11 generally further comprises an interior lock housing 115, the interior lock housing 115 housing the internal locking lever 113 and the internal locking sleeve 114, the internal locking sleeve 114 being axially located in the interior lock housing 115, the internal locking lever 113 being axially located in the internal locking sleeve 114.
  • locking can be achieved through various methods such as delayed electric locking, elastic reset locking, or manual mechanical locking.
  • the clutch transmission wheel 14 may utilize a ratchet mechanism.
  • an elastic ejector pin 152 is situated on the slipping collar 15.
  • the elastic ejector pin 152 consistently engages with the teeth 142 of the ratchet, regardless of whether the slipping collar 15 and the clutch transmission wheel 14 are engaged or disengaged. For instance, when viewing inwardly from the outer side of the door, counterclockwise rotation of the thumb turn 12 facilitates unlocking, while clockwise rotation initiates locking.
  • the elastic ejector pin 152 intermittently misses the teeth 142 of the ratchet, preventing the slipping collar 15 from rotating. Consequently, the first mechanical unlocking assembly 102 remains idle, and the thumb turn 12 remains stationary. Furthermore, since doors may open to the left or right, the ratchet can be flipped accordingly for adaptation. For example, the ratchet may be adjusted so that its teeth 142 extend and protrude in a counterclockwise direction. The adjustment of the ratchet depends on the specific installation environment.
  • the electric actuator 201 includes an electric motor 23 and a transmission member 24.
  • the electric motor 23 is connected electrically to the control circuit board 21, while the transmission member 24 is affixed to the output shaft of the electric motor 23. This transmission member 24 extends into the notch 294, establishing a transmitting connection with the driven end 161.
  • the transmission member 24 is configured as a cam featuring a transmitting recessed groove 241.
  • the driven end 161 fits into this recessed groove 241, and when the cam is driven to rotate by the electric motor 23, it moves the driven end 161. Consequently, the fork body 163 shifts, further prompting the slipping collar 15 to move relative to the internal locking sleeve 114, thereby engaging with the clutch transmission wheel 14 for transmission purposes.
  • This transmission member 24 setup can be based on the rotating cam design disclosed in CN218759296U .
  • the second mechanical unlocking assembly 202 comprises three main components: the interior handle 25, the inner coupling shaft 26, and the inner drive wheel 27.
  • the interior handle 25 is affixed to the inner end of the inner coupling shaft 26.

  • the inner drive wheel 27 is set in a sliding connection to the outer end of the inner coupling shaft 26, being peripherally limited by it. This configuration allows the inner drive wheel 27 to slide axially along the inner coupling shaft 26 while remaining in co- rotation with it.
  • a keeper spring 28 is positioned between the inner drive wheel 27 and the smart control box 200. The elastic force exerted by the keeper spring 28 ensures that the inner drive wheel 27 maintains its transmitting connection with the slipping collar 15.
  • the electric actuator 201 can overcome the elastic force of the keeper spring 28 to push the slipping collar 15 into motion.
  • the inner coupling shaft 26 can serve to axially limit the clutch transmission wheel 14.
  • the lock body 100 is designed with a keyless structure, meaning that the user can solely unlock the first mechanical unlocking assembly 102 from outside the door using a smart control unit to operate the electric actuator 201.
  • the exterior cylinder core 13 comprises two main components: an exterior lock housing 131 and an external locking lever 132.
