Description

TECHNICAL AREA

The present application belongs to the technical field of electronic locks and relates in particular to an intelligent lock

STATE OF THE ART

Nowadays, with the improvement of security awareness among people, more and more consumers have made a choice to use more convenient and secure electronic smart locks. In the smart locks in use today, a main control board is usually provided within the lock. Several modules with information reception or acquisition are integrated on the main control board. When these modules have received the relevant information, they are transmitted to the main control board, and then the main control board sends relevant instructions to the drive motor to unlock the electronic lock itself. Due to the interaction of the mechanical structure, the unlocking process can then be implemented, for example by swiping the card, identifying the password or the fingerprint. However, the existing intelligent locks are usually only equipped with one set of control arrangement, i.e. a control board for controlling the drive motor and the transmission mechanism. If the control arrangement fails, problems such as incorrect unlocking or non-unlocking will arise, which lead to safety risks, inconvenience in use, or the like.

Similarly, the second control assembly 900 includes a second main control board 910, a second drive mechanism 920 and a second transmission mechanism 930; the second main control board 910 is in the first mounting space 110 built-in, the second transmission mechanism 930 and the second drive mechanism 920 are both built in the main body member 210. The second main control board 910 is electrical with the second drive mechanism 920 connected. When the first control arrangement 800 is stationary, the second transmission mechanism 930 is driven by the second drive mechanism 920 driven to the cam element 220 to rotate relative to the main body member 210.

It should be noted that the first control arrangement 800 and the second control arrangement 900 of the present intelligent lock are two independent control systems, both of which can complete the intelligent unlocking process under appropriate conditions. In actual use, the user can swipe the card, enter password or fingerprint or use mobile phone app, so that the first main control board 810 or the second main control board 910 which is in the foregrip 100 receives relevant information. It is then judged that the information is correct and the control command is issued. After the appropriate drive mechanism has received the relevant control command, it can control the cam element 220 drive to rotate through the corresponding transmission mechanism, and take the mechanical structure on the intelligent lock with it to rotate during the rotation, thereby achieving the unlocking mechanism. Hereby, the first drive mechanism 820 and the second drive mechanism 920 Driving motors, i.e. motors, are, but not limited to, using the axial direction, i.e. the length direction of the smart lock as the front and rear directions, is the fore grip 100 via a profile square shaft 300 connected to the front end of the lock core 200.

The complete unlocking process is thus implemented. In this way, in actual use, the first control device 800 can be used as the main control system for daily use, and the second control device 900 can be used as a backup control system. As a result, not only can various intelligent unlocking methods be implemented, but the unlocking process can also be implemented via the second backup control arrangement 900 if the main control system fails due to the backup control system. Therefore, the risk that the smart lock cannot be used in only one set of control systems can be effectively avoided, and the convenience of using the smart lock is greatly improved.
