Description

Technical Field

[0001] The utility model relates to the field of locks, in particular to a passive lock core and a lock. Background Art

[0002] A passive lock is a motor-driven lock. Since there is no power source to drive the motor inside the lock body, it is called a passive lock.

[0003] The power supply of current passive locks is installed inside the key. After the key contacts the lock body, the power supply inside the key supplies power to the lock body and enables information exchange between the lock body and the key. After the information and key match successfully, the motor drives the locking mechanism inside the lock body to achieve the effect of electric unlocking. Passive locks can achieve the effect of opening multiple locks with one electronic key. Compared with mechanical locks opened with a single key, it can reduce the work of users carrying and finding keys for specific purposes.

[0004] Most of the current passive locks are newly designed. This type of passive lock does not consider the problem of mechanical lock cores and passive lock cores being commonly used in lock bodies, so newly designed passive locks can only use pre-designed passive lock cores; since there are many mechanical locks on the market, and mechanical locks are gradually beginning to transition to passive locks, the cost of replacing the entire lock is relatively high, and there is a demand to replace existing mechanical locks with passive locks by replacing the lock cores. Therefore, it is necessary to develop a lock core and lock that can replace the lock core according to needs, change the mechanical lock to a passive lock, or change the passive lock back to a mechanical lock according to actual needs.
