  • the housing seat unit 61 has a seat frame 611 mounted on the externally facing surface 21 of the door panel 2, a housing shell 612 disposed outwardly of and covering the seat frame 611, and a power supply compartment 613 defined by the seat frame 611 and the housing shell 612.
  • the clutch unit 62 has a clutch driving member 65, an output axle 66, a clutch pin 67, a biasing member 68 and a ring-shaped retaining member 69.
  • the clutch driving member 65 is rotatably mounted on the housing seat unit 61 about a first axis (L1) in the first direction, and is engaged with the handle 4.
  • the clutch driving member 65 has an engaging end portion 656 which is engaged with the handle 4, a driving end portion 651 which is opposite to the engaging end portion 656 in the first direction and which has a receiving slot 652 that extends along the first axis (L1) for the output axle 66 to be rotatably received therein, and a communicating bore 653 that extends radially to be in spatial communication with the receiving slot 652 for the clutch pin 67 to be movably inserted therein.
  • the communicating bore 653 has a smaller-diameter segment 654 and a larger-diameter segment 655 formed proximate to and distal from the output axle 66, respectively, and a shoulder 657 formed between the smaller-diameter segment 654 and the larger-diameter segment 655.
  • the output axle 66 is rotatably received in the receiving slot 652 of the clutch driving member 65 , and is engaged with the deadbolt 51.
  • the output axle 66 has an embedded groove 661 extending along a second axis (L2) that is transverse to the first axis (L1).
  • the first axis (L1) is normal to the externally facing surface 21 of the door panel 2
  • the second axis (L2) is perpendicular to the first axis (L1).
  • predetermined angles may be included between the first and second axes (L1, L2), and between the first axis (L1) and the externally facing surface 21 as required.
  • the clutch pin 67 extends along the second axis (L2), and is disposed in and movable relative to the clutch driving member 65 along the second axis (L2) .
  • the clutch pin 67 has a flange 671 extending radially from a periphery thereof.
  • the clutch pin 67 is operative to move between an engaged position (see FIG. 5 ), where the clutch pin 67 is engaged in the embedded groove 661 of the output axle 66 when the communicating bore 653 is aligned with the embedded groove 661 along the second axis (L2), so as to allow synchronous rotation of the output axle 66 with the clutch driving member 65 to establish a connection between the handle 4 and the deadbolt 51, and a disengaged position (see FIG. 4 ), where the clutch pin 67 is disengaged from the embedded groove 661 so as to allow an idle rotation of the output axle 66 relative to the clutch driving member 65 to disconnect the connection between the handle 4 and the deadbolt 51.
  • the biasing member 68 is in the form of a coil spring which is sleeved around the clutch pin 67 and has two ends abutting against the shoulder 657 and the flange 671, respectively, to bias the clutch pin 67 away from the output axle 66.
  • the biasing member 68 may be an elastic block or the like.
  • the retaining member 69 is disposed over the larger-diameter segment 655 and has a through hole 691 which extends therethrough along the second axis (L2) for permitting movement of the clutch pin 67 and which has a diameter smaller than that of the flange 671 to stop the movement of the clutch pin 67 away from the output axle 66.
  • the driving unit 63 is disposed on the housing seat unit 61, and has a motor 631 which is disposed within the seat frame 611, and a pressing member 632 which is actuated by the motor 631 to be moved relative to the clutch driving member 65.
  • the pressing member 632 has a pressing end surface 633 which abuts against and presses on the clutch pin 67, and two guiding slope surfaces 634 which are adjoined to the pressing end surface 633.
  • the pressing member 632 is made of a polyoxymethylene (POM) material to minimize wearing by the clutch pin 67, or the like with high stiffness and lower friction.
  • POM polyoxymethylene
  • the power supply unit 64 is disposed in the power supply compartment 613 and is electronically connected with the motor 631 and the unlocking device 7.
  • the power supply unit 64 is a dry cell pack or a rechargeable battery pack to supply power to the motor 631.
  • the handle 4 is rotatably disposed on the housing seat unit 61.
  • the motor 631 is actuated to move the pressing member 632 to press and move the clutch pin 67 along the second axis (L2) to the engaged position.
  • turning of the handle 4 can rotate the clutch driving member 65 to bring an angular movement of the clutch pin 67 relative to the pressing member 632 along a path (a) that surrounds the second axis (L2), and a torque is transmitted through the clutch driving member 65, the clutch pin 67 and the output axle 66 to retreat the deadbolt 5 to the unlocking position.
  • the clutch pin 67 can be retained in the embedded groove 661 against the biasing action of the biasing member 68.
  • the clutch pin 67 is unintentionally disengaged from the embedded groove 661 during rotation of the handle 4 (i.e. when the communicating bore 653 is not aligned with the embedded groove 661)
  • the user can rotate the handle 4 back to its original position (i.e. a parallel position) such that the clutch pin 67 is turned along the path (a) .
  • the movement of the clutch pin 67 is guided by one of the guiding slope surfaces 634 which is adjoined to the pressing end surface 633 along the path (a) to reach the pressing end surface 633.
  • the clutch device 6 can be conveniently detached and replaced with usage of a hand tool without the need to remove component parts in the accommodation space 24 of the door panel 2. Additionally, the assembly and disassembly of the door lock 3 are convenient to conduct. For example, when it is desired to replace the unlocking device 7, the clutch device 6 is merely required to be replaced, which renders the operation convenient.
  • the unlocking device 7 utilizes a face recognition technology.
  • the unlocking device 7 is in the form of a digital code lock.
