DETAILED DESCRIPTION

FIG. 1 is an electronic locking assembly 100, according to a first embodiment, including an electronic lock 60 for physically locking a device 200 (such as a bicycle), and an electronic key 10 for unlocking the electronic lock 60.

The electronic key 10 includes a first wireless charging module 11, a first battery 13, a first memory 15, a first signal transceiver 17, and a switching button 18. The first wireless charging module 11 is electrically connected to the first battery 13 to charge the first battery 13. In one embodiment, the first wireless charging module 11 includes a first coil, which can cooperatively form a closed electrical loop with the first battery 13. The first battery 13 is electrically connected to the first memory 15 and the first signal transceiver 17 through the switching button 18, and powers the first memory 15 and the first signal transceiver 17 when the switching button 18 is actuated.

The first memory 15 stores a first password. The first signal transceiver 17 encodes the first password into a first wireless signal and transmits the first wireless signal into the electronic lock 60.

The electronic lock 60 is integrated with the device 200, and includes a main body 61, a locking button 601, a processor 602, a wired charging module 62, a second wireless charging module 63, a second battery 64, a second memory 65, a second signal transceiver 66, a comparator 67, and a password resetting module 68.

The main body 61 physically locks or unlocks the device 200. The locking button 601 controls the main body 61 to physically lock the device 200. In this embodiment, the main body 61 has a cable like a bicycle lock, and the main body 61 locks the bicycle to a desk or a pole.

The wired charging module 62 is electrically connected between the second battery 64 and an external alternating-current (AC) power supply 300, and charges the second battery 64. The second wireless charging module 63 is electrically connected to the external power supply 300, and cooperates with the first wireless charging module 11 to charge the first battery 13. In particular, the second wireless charging module 63 includes a coil and obtains AC current from the external power supply 300 to generate a variable electromagnetic field. The first wireless charging module 11 is influenced by the variable electromagnetic field to generate induced currents to charge the first battery 13.

The second battery 64 powers the main body 61, the locking button 601, the processor 602, the second memory 65, the second signal transceiver 66, the comparator 67, and the password resetting module 68.

The second memory 65 stores a second password. The second signal transceiver 66 receives and decodes the first wireless signal into the first password. The processor 602 sends the first password from the second signal transceiver 66 and the second password in the second memory 65 to the comparator 67. The comparator 67 compares whether the first password and the second password match, and thus controls the main body 61 to unlock the device 200 or to keep the device 200 locked. In particular, if the first password and the second password match, the main body 61 unlocks the device 200, and if the first password and the second password do not match, the main body 61 keeps the device 200 locked.

The password resetting module 68 resets the first password and the second password synchronously, and includes a reset button 680, a password input unit 682, a confirmation button 683, and a signal lamp 684. The password input unit 682 may be a touch panel or a keyboard.

When the reset button 680 is actuated in an on state, the processor 602 switches the electronic locking assembly 100 to a password resetting mode. When the reset button 680 is actuated in an off state, the processor 602 switches the electronic locking assembly 100 to a normal mode (i.e. the electronic locking assembly 100 physically locks or unlocks the device 200).

When the electronic locking assembly 100 is in the password resetting mode, a user can input a number of first characters through the password input unit 685. The processor 602 further stores the first characters in the second memory 65 as a third password and sends the first characters to the second signal transceiver 66. The second signal transceiver 66 further encodes the first characters into a number of third wireless signals one by one. In addition, transmits the third wireless signals sequentially to the electronic key 10 (such as, when the password input unit 682 outputs “1”, and “1” is encoded into a third wireless signal to be transmitted first, then the password input unit 682 outputs “2”, and “2” is encoded into a third wireless signal to be transmitted next time). The first signal transceiver 17 further receives the third wireless signals and decodes the third wireless signals into a number of second characters to be stored in the first memory 15 as a fourth password.

During the password resetting process, when the electronic key 10 is within the transmitting range of third wireless signals from the second signal transceiver 66, the key 10 can receive the third wireless signals; when the electronic key 10 is outside the transmitting range of third wireless signals from the second signal transceiver 66, the key 10 can not receive the third wireless signals, therefore, sometimes, the second characters stored in the first memory 15 do not match with the first characters stored in the second memory 65.

Where upon actuation of the confirmation button 683, the processor 602 determines that the input of the third password has been finished. The first signal transceiver 17 encodes the fourth password into a fifth wireless signal and transmits the fifth wireless signal to the second signal transceiver 66, the second signal transceiver 66 receives the fifth wireless signal and decodes the fifth wireless signal into the fourth password. The processor 602 sends the third password and the fourth password to the comparator 67, the comparator 67 compares whether the third password and the fourth password match. If the third password and the fourth password match, the signal lamp 684 shows green, the first password and the second password are deleted, and the third password and the fourth password are set as new passwords of the electronic key 10 and the electronic lock 60 respectively. If the third password and the fourth password do not match, the signal lamp 684 shows red, the third password and the fourth password are deleted, the first password and the second password remain set as passwords of the electronic key 10 and the electronic lock 60 respectively.

Referring to FIG. 2, according to a second embodiment, an electronic locking assembly 200 is substantially same as the electronic locking assembly 100 except that the confirmation button 683 is replaced with a timer 700.

The timer 700 stores a predetermined time interval, and tests a first time interval when the password input unit 682 does not output signal after the password input unit 682 outputs at least one signal. In addition, a second time interval when the password input unit 682 does not output any signal since the electronic locking assembly 100 is switched to the password resetting mode. The processor 602 further compares the first time interval and the second time interval tested by the timer and the predetermined time respectively, if the first time interval is greater than the predetermined time interval, the processor 602 determines that the password input has been finished. If the second time interval is greater than the predetermined time interval, the processor 602 determines that the user does not want to reset the passwords, and switches the electronic locking assembly 100 to the normal mode.

In other embodiments, the locking button 601 can be omitted, when the second signal transceiver 66 cannot receive the first wireless signal, the processor 602 controls the main body 61 to automatically lock the device 200.

It will be understood that the above particular embodiments and methods are shown and described by way of illustration only. The principles and the features of the present disclosure may be employed in various and numerous embodiments thereof without departing from the scope of the disclosure as claimed. The above-described embodiments illustrate the scope of the disclosure but do not restrict the scope of the disclosure.
