Bi-directional communication coded lock

Abstract

The invention relates to a bi-directional communication coded lock. The bi-directional communication coded lock comprises a lock body, a lock core assembly, a key assembly and a lock bolt assembly, wherein the key assembly comprises a key plug, a key handle and a key control circuit board; the lock core assembly comprises a lock core shell and a lock core control circuit board; a plurality of contactors are respectively arranged in a key insertion hole and the key plug of the lock core shell; when the key plug is inserted into the key insertion hole and rotated in place, each contactor is correspondently communicated, so that the circuit of a power supply driving control circuit is conducted, and each circuit board is electrified; a lock core control chip and a key control chip, which are used for transmitting verification passwords and controlling the lock bolt assembly to be unlocked or locked according to the passwords, are arranged in a lock core control chip working circuit and a key control circuit board. By adopting the bi-directional communication coded lock, the contact matching structure of the lock core assembly and the key assembly is simplified; moreover, the lock core assembly and the key assembly communicate with each other through a single line so as to transmit and verify the passwords, so that the lock structure is simplified, the electricity consumption is small, and convenience in machining is realized.

Description

technical field [0001] The invention relates to a two-way communication password lock, which can be used in various high-grade locks such as anti-theft doors, automobiles, safes and the like. Background technique [0002] With the increasing material wealth of the society, security and anti-theft has become a hot issue of social concern. "Lock", as the iron general guarding the door, people have higher and higher requirements for it. Ordinary mechanical locks are affected by their manufacturing process, and their passwords are limited to a certain extent. They are no longer suitable for important places. However, all kinds of electronic combination locks generally have complex structures, large power consumption, high cost, inconvenient use and inconvenient password settings. Defects such as limitations or poor safety performance. Contents of the invention [0003] The purpose of the present invention is to provide a two-way communication combination lock, which not only ...
