Abstract

A wirelessly charging electronic lock device includes an electronic key and a electronic lock, a key code and a pre-stored matching code are pre-stored in the electronic key, an electronic lock code is pre-stored in the electronic lock, the electronic key includes a wireless charging device and a first wireless signal device, the wireless charging device charges the electronic device by wireless transmission, the electronic lock includes a wireless charging receiving device, a second wireless signal device, and a processing unit, the processing unit is configured to figure out a current matching code, the current matching code is compared with the pre-stored matching code, which is validated as to whether the electronic key matches with the electronic lock.

Claims

1. A wirelessly charging electronic lock device, comprising:

an electronic key comprising a wireless charging device and a first wireless signal device; and

an electronic lock comprising a wireless charging receiving device, a second wireless signal device, and a processing unit;

wherein a key code and a pre-stored matching code are pre-stored in the electronic key, an electronic lock code is pre-stored in the electronic lock, the first wireless signal device is configured to send the key code and the pre-stored matching code and receive the electronic lock code;

wherein the wireless charging device charges the electronic lock through the wireless charging receiving device by wireless transmission, the second wireless signal device is configured to receive the key code and the pre-stored matching code and send the electronic lock code;

wherein the processing unit is configured to calculate a current matching code according to a calculation formula, the current matching code is compared with the pre-stored matching code, which is validated as to whether the electronic key matches with the electronic lock, and if matching, the electronic lock is unlocked, and if not matching, the electronic lock remains locked; and

wherein the calculation formula of the current matching code is Code III1=Code I XOR Code II+Code I AND Code II, wherein Code III1 is the current matching code, Code I is the key code, and Code II is the electronic lock code.
