Description

Electronic lock

Technical Field

The utility model belongs to the technical field of the tool to lock and specifically relates to an electronic lock opened and close through electric control.

Background

At present, the lock is roughly classified into a mechanical lock and an electronic lock. The mechanical lock realizes opening and closing by controlling the straight line telescopic motion of the lock tongue through the mechanical cooperation of the lock core and the linkage mechanism thereof, and in order to realize automatic locking of the lock in collision, the lock tongue of the lock can adopt a single-arc-surface lock tongue and is provided with a return spring. This mechanical lock is equipped with key or code disc usually, when unblanking, needs to rotate lock core or code disc many times, especially is furnished with the tool to lock of key, when the key wrench movement, need be with the help of wrist power to still there is the hand condition of coming and going a lot of wrench movements, thereby it is comparatively hard to cause to unblank, complex operation and inconvenience, and the key that the quality is poor is broken at the in-process of wrench movement very easily moreover, and the lockhole is blocked up, the flexible not smooth scheduling problem of spring bolt. Some electronic locks mainly replace the lock core into the motor on the basis of the aforementioned mechanical lock, and be furnished with the circuit board of taking password or fingerprint and control the motor work, in order to realize that the spring bolt stretches out and draws back and reach the function that the tool to lock opened and close, this kind of electronic lock can overcome the not enough that mechanical lock exists to a certain extent, however, the addition of motor can make the whole volume change of tool to lock, link gear increases and complicated, consequently, most electronic locks are all not suitable for the less tool to lock of volume too much, for example, products such as drawer, password type drawer cabinet and filing cabinet. The electronic lock adopts the linear telescopic lock tongue, and the unlocking or locking needs to be driven by the motor, so that the use frequency of the motor is high, the power consumption is high, and the electronic lock is easy to cause insufficient power and cannot be unlocked. In addition, when the lock is unlocked, the motor needs to control the lock tongue to retract into the lock hole through the linkage mechanism, and in the state, the lock tongue with the return spring is pressed for a long time, so that the lock tongue is easy to damage and lose efficacy, and the automatic locking function of the lock tongue can be failed.

The chinese utility model specification (publication No. CN 202181767U) discloses an electronic lock, which comprises a lock case, wherein a motor 3, a transmission mechanism, a latch bolt assembly and a circuit board 14 are arranged in the lock case.
