High reliability passive electronic lock with extensible function

Abstract

The invention discloses a high reliability passive electronic lock with an extensible function. The high reliability passive electronic lock comprises a lock shell, a front lock cylinder, an electric shifting piece, a rear lock cylinder, a key inserting opening and a circuit board. The front lock cylinder and the rear lock cylinder both can be mounted inside the lock shell in a rotatable mode, the electric shifting piece is mounted on the front lock cylinder, and the electric shifting piece and the key inserting opening are both electrically connected with the circuit board. The electric shifting piece can be driven by the circuit board to move, so that the front lock cylinder and the rear lock cylinder are in linkage connection through the electric shifting piece. The high reliability passive electronic lock with the extensible function is characterized in that the circuit board, the front lock cylinder and the rear lock cylinder are separately mounted inside the lock shell, a first electric connection lead between the electric shifting piece and the circuit board is arranged outside the front lock cylinder in a winding mode, and a space capable of sufficiently containing the first electric connection lead is arranged between the front lock cylinder and the lock shell. By means of the high reliability passive electronic lock with the extensible function, the limitation of an existing passive electronic lock to the function extension space of the circuit board is removed, and the electrical connecting reliability of the circuit board and the electric shifting piece in the lock cylinders can be guaranteed.

Description

technical field [0001] The invention relates to a high-reliability passive electronic lock with expandable functions. Background technique [0002] Compared with the access control system, passive electronic locks have the advantages of low implementation cost, energy saving and environmental protection, and have been widely used in various occasions, especially in important management occasions that need to record lock opening and closing operation events and operation occurrence time, such as important The door of the warehouse, oil pipeline valves, high-voltage electrical switches, etc. figure 1 Shown is a kind of existing passive electronic lockset, and this lockset comprises padlock housing, front lock cylinder 1, electric paddle 2, rear lock cylinder 3, key insertion interface 4 and circuit board 5; Front lock cylinder 1 and rear The lock cylinder 3 can be rotatably installed inside the padlock housing, and the electric pick 2, the circuit board 5 and the key insertio...
