Description

Technical Field

[0001] The utility model relates to the technical field of intelligent locks, in particular to an intelligent lock for a security door. Background Art

[0002] Smart door locks are improved upon traditional mechanical locks and are more intelligent and simple in terms of user security, identification, and management. Smart door locks are the executive components of door locks in access control systems. Smart door locks are different from traditional mechanical locks and are composite locks that are safe, convenient, and technologically advanced.

[0003] For example, a smart lock disclosed in publication number CN220184867U has the following beneficial effects: the light-type solar cell can absorb light energy and convert the energy into electrical energy and store it inside the battery assembly, providing backup power support for the smart lock body for backup power supply. When the dry battery assembly used for the main power supply of the smart lock body is exhausted, the weak-light solar cell can also provide the smart lock body with enough power to unlock the lock, thereby improving the convenience of the smart lock body during use; the smart lock body can be unlocked by password, fingerprint, and NFC technology reading, and there are various unlocking methods. When one of them cannot be used, it can be unlocked in time by other methods, thereby improving the flexibility of the smart lock body during use; when the power of the smart lock body is too low, the power indicator light lights up to remind personnel to replace the dry battery assembly in time. When the smart lock body is violently damaged by external force, the thin wire connected to the disconnection alarm will be disconnected, causing the disconnection alarm to sound and light alarm for a period of time.

[0004] Regarding the above solution: The reference document provides backup power for the smart lock body by converting light energy into electrical energy. However, when the smart lock is installed in a place where sunlight cannot reach, light energy conversion cannot be performed. When the power in the smart lock is exhausted, the smart lock cannot be used anymore. At the same time, with the long-term use of the smart lock, the internal battery will age, causing a short circuit inside the smart lock, which is inconvenient for users to repair the smart lock.
