Description
Technical Field
[0001] The utility model relates to the technical field of electronic password locks, in particular to an electronic password lock. Background Art
[0002] Locks are used in many scenarios in life, such as anti-theft doors, cars, safes, etc. However, traditional mechanical locks can no longer meet everyone's needs, because the key of a mechanical lock can be quickly copied through a special machine, which greatly reduces the security of the lock.
[0003] With the development of information technology, electronic password locks have emerged. Electronic password locks are electronic products that control the operation of circuits or chips (access control systems) through password input, thereby controlling the closing of mechanical switches to complete unlocking and locking tasks.
[0004] With the advancement of technology, the performance and security of current electronic password locks have surpassed mechanical locks. However, electronic password locks need to rely on power to achieve the unlocking function. When the power is short of power or there is a problem with the circuit, the unlocking function cannot be achieved. Due to the limitations of electronic devices, the electronic password locks developed in the past are of few types and have poor confidentiality. The most basic ones only rely on the simplest analog electronic switches to achieve this, which are simple to make but very unsafe.
[0005] Therefore we propose an electronic password lock to solve the above problems. Utility Model Content
