Description

Technical Field

[0001] This utility model relates to the field of lock technology, and more specifically to a combined IoT smart bouncy lock. Background Technology

[0002] In today's society, with the improvement of people's living standards and the continuous advancement of technology, the requirements for security locks are also increasing. As an important tool for protecting personal and property safety, locks have received widespread attention for their security, convenience, and intelligence. However, existing lock technology still has many shortcomings in practical applications and urgently needs improvement and innovation.

[0003] Traditional spring-loaded locks are mostly mechanical locks, which rely primarily on the physical insertion and rotation of a key to unlock and lock. These mechanical locks have several security vulnerabilities, such as low security, susceptibility to prying or technical unlocking, and the need for brute force when the key is lost, which can damage the lock itself.

[0004] With the rapid development of electronic technology, electronic spring-loaded locks have emerged. Compared to traditional mechanical spring-loaded locks, electronic spring-loaded locks offer significantly improved security. They can be opened with an electronic key, enhancing the security of traditional mechanical locks, and also easily enabling automatic recording of unlocking operations. However, electronic spring-loaded locks are not without their flaws. Due to limitations in lock size and installation, they are generally passively designed, requiring power from the electronic key for unlocking. This design means the lock is normally powered off, making it impossible to monitor the opening and closing status of the lock door and to track the usage of the protected enclosure or facility in real time. Furthermore, the requirement for power from the electronic key for unlocking makes electronic key management difficult to meet on-site usage requirements.

[0005] Therefore, developing a combined IoT-enabled smart bouncy lock that can not only effectively improve the security of locks but also achieve intelligent management and monitoring is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
