A high-reliability passive electronic lock with scalable functions

Abstract

The invention discloses a high-reliability passive electronic lockset with expandable functions, which comprises a lockset housing, a front lock cylinder, an electric paddle, a rear lock cylinder, a key insertion interface and a circuit board; the front lock cylinder and the rear lock cylinder are both It is rotatably installed inside the lock housing, and the electric pick is installed on the front lock cylinder. The electric pick and the key insertion interface are respectively electrically connected to the circuit board. The electric pick can be driven by the circuit board to make the front lock cylinder and the key insert The rear lock cylinder is linked and connected through the electric paddle, which is characterized in that the circuit board is installed inside the lock housing separately from the front lock cylinder and the rear lock cylinder, and the first electrical connection lead coil between the electric paddle and the circuit board The coil is arranged outside the front lock core, and there is a space enough to accommodate the first electrical connection lead wire between the front lock core and the lock housing. The invention removes the limitation of the function expansion space of the circuit board by the existing passive electronic lockset, and can ensure the reliability of the electrical connection between the circuit board and the electric plectrum in the lock cylinder.

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...
