  • the padlock 1600 When the padlock 1600 is in the active state, it can be unlocked by the electronic-lock mechanism as follows.
  • the padlock 1700 also has a processor 520, a driving electronic circuit 530 as shown in Figure 31 , the driving electronic circuit 530 is arranged to cause the shaft 1691 of the solenoid 1690 to move halfway downward upon receiving a combination code from the keypad 1740 (see Figure 38 ) or a correct password conveyed in a wireless signal from an electronic device 700 (see Figures 34 , 35A-35E ).
  • the shaft 1691 of the solenoid 1690 is moved halfway downward, the shaft 1691 is disengaged from the locking hole 1662 of the single-hole latch 1660 while the shaft 1691 is still located in the activating hole 1671 of the double-hole latch 1670.
  • a spring 1664 at the single-hole latch 1660 is arranged to urge the single-hole latch 1660 to remain in contact with the locking ring 1680.
  • the shackle 1700 can be pulled upward to disengage the short leg 1701 from the blocking plate 1610. The shackle 1700 can then be rotated to change the combination lock 1600 from the locked mode to the opened mode as shown in Figure 52 .
  • the rotatable cam 1640 is also rotated in the same manner.
  • the driving pin 1611 of the block plate 1610 is movably engaged in the pin slope 1641 of the rotatable cam 1640, the pin slope 1641 causes the blocking plate 1610 to move downward relative to the fixed cam 1620 so as to release the short leg 1701 of the shackle 1700.
  • the single-hole latch 1660 remains engaged with the locking ring 1680, the shackle 1700 can be rotated to change the padlock 1600 from the locked position to the opened position.
  • the padlock 1600 When the padlock 1600 is in the deactivation state as a result of a command from a first-level user of the detached electronic device 700, the padlock 1600 cannot be unlocked by a correct key or by a combination code entered via the touch panel 1740 by any user.
  • the first-level user can activate the "deactivation" icon 716 on the display 710 of the electronic device 700 to disable both the touch panel 1740 and the key-lock mechanism of the padlock 1600.
  • the shaft 1691 of the solenoid 1690 is located in both the locking hole 1662 of the single-hole latch 1660 and the activating hole 1671 of the double-hole latch 1670.
  • a wireless signal indicative of the deactivation function is conveyed to the padlock 1600 and received by the signal receiver 515 on the padlock 1600 as shown in Figure 37B .
  • the driving electronic circuit 530 is configured to send out two types of signals for energizing the solenoid 1690: an activating signal 907 and a deactivating/re-activation signal 908.
  • the driving electronic circuit 530 in Figure 37B is arranged to send out the activating signal 907 when the combination code entered via the touch pad 1740 is valid or the password indicated in the wireless signal matches the combination code.
  • the deactivation signal 908 is provided only when the user of the first level activates the deactivation icon 716 or the reactivation icon 717 (see Figure 35F ).
  • the shaft 1691 of solenoid 1690 is retracted halfway to release the single-hole latch 1660.
  • the shaft 1691 of solenoid 1690 is retracted further downward to release both the single-hole latch 1660 and the double-hole latch 1670.
  • a spring 1674 at the double-hole latch 1670 urges the double-hole latch 1670 to move into the de-activating cutout 1612 of the blocking plate 1610.
  • the de-activating hole 1672 of the double-hole latch 1670 is aligned with the shaft 1691 of the solenoid 1690.
  • the groove 661 of the single-hole latch 1660 is kept in the locking ring 1681 of the locking ring 1680 by the urging force of the spring 1664 (see Figure 51 ).
  • the latch hole 1662 of the single-hole latch 1660 is also aligned with the shaft 1691. After a predetermined time period, such as 10 seconds, the shaft 1691 is moved into the de-activating hole 1672 of the double-hole latch 1670 and the latch hole 1662 of the single-hole latch 1660 as shown in Figure 54B .
  • the padlock 1600 can only be unlocked with a combination code conveyed from the mobile device 700 via a wireless signal.
  • a user of the first, second or third access level can unlock the padlock 1600 with a correct combination code conveyed from the mobile device 700.
  • only a user of the first access level can unlock the padlock 1600 via the wireless signal.
  • a user of the first or second access level can unlock the padlock 1600 remotely.
  • the padlock 1600 When the padlock 1600 is in the deactivated state, only the user of a first level can "re-activate” the padlock 1600 by activating the "re-activation” icon 717.
  • the driving electronic circuit 530 sends out a deactivating/re-activating signal 908 to cause the shaft 1691 of the solenoid 1690 to retract fully to release both the single-hole latch 1660 and the double-hole latch 1670.
  • the single-hole latch 1660 is urged by the spring to move away and disengaged from the ring neck 1681 of the locking ring 1680. As such, the shackle 1700 can be pulled upward to unlock the padlock 1600.
  • the shackle 1700 can be rotated away from the blocking plate 1610 and the fixed cam 1620 as shown in Figure 55 . While the shaft 1691 of the solenoid 1690 is still disengaged from the double-hole latch 1670, a re-activating key 1730 can be inserted into the re-activating hole 1621 of the fixed cam 1620 to push the rod 1630 downward. As the rod 1630 is moved downward, the rod slope 1631 of the rod 1630 applies a force against the latch edge 1673 of the double-hole latch 1670, causing the double-hole latch 1670 to move away until the activating hole 1671 of the double-hole latch 1670 is aligned with the shaft 1691 of the solenoid 1690.
  • the shaft 1691 is moved back into the activating hole 1671.
  • the key-lock mechanism can be used to unlock the padlock 1600.
  • the same signal 908 is used both in the deactivation and the reactivation of the padlock 1600.
  • the signal 908 is only arranged to cause the shaft 1691 of the solenoid 1690 to retract fully within a predetermined period of the time. Therefore, the "deactivation" icon 716 and the “re-activation” icon 717 are effectively the same. Their only function is to cause the shaft 1691 of the solenoid to retract fully.
  • the padlock 1600 has also has a battery to power the solenoid 1690 and a charging slot (not shown).
  • a battery 510 as depicted in Figure 31 is representative of the battery used in the padlock 10, 420 or 1600.
