Electronic lock body

Abstract

The invention relates to an electronic lock body which comprises a dead bolt assembly, a dead bolt transmission device, a motor assembly and a lock cylinder, the lock cylinder is connected with the dead bolt assembly, the dead bolt transmission device comprises a pulling rod and a motor gear, and an arc-shaped groove is formed in the motor gear; the pulling rod is provided with a pulling rod bulge; the motor gear is driven by the motor assembly, and the two ends of the arc-shaped groove act on the pulling rod protrusions respectively so that the dead bolt can stretch out of the lock body or retract into the lock body. After the dead bolt extends out of the lock body or retracts into the lock body, the motor gear rotates to a reset position, and the pulling rod protrusion slides along the arc-shaped groove in the process that the pulling rod of the lock cylinder pulls the dead bolt assembly to enable the dead bolt to extend out of the lock body or retract into the lock body. The lock cylinder has the advantages that the pulling rod protrusion slides along the arc-shaped groove and does not touch the two ends of the arc-shaped groove, so that in the mechanical unlocking process through the lock cylinder, the pulling rod does not drive the motor gear but idles relative to the motor gear, and unlocking or locking is quite labor-saving.

Description

technical field [0001] The invention relates to an electronic lock body. Background technique [0002] The electronic lock includes a square tongue assembly, a square tongue transmission device, a motor assembly, a PCB board, and a lock body control module. The PCB board is connected to the lock body control module, and the square tongue transmission device is connected to the square tongue assembly and the motor assembly. The signal of the lock body control module drives the motor assembly to act on the square tongue transmission device, so that the square tongue of the square tongue assembly protrudes or retracts into the lock body to achieve the purpose of locking or unlocking. In order to achieve the purpose of mechanical unlocking, electronic locks are generally equipped with There is a mechanical unlocking device, and the purpose of mechanical unlocking is achieved through a key. However, after the existing electronic lock is unlocked, the square tongue transmission de...

[0002] The electronic lock includes a square tongue assembly, a square tongue transmission device, a motor assembly, a PCB board, and a lock body control module. The PCB board is connected to the lock body control module, and the square tongue transmission device is connected to the square tongue assembly and the motor assembly. The signal of the lock body control module drives the motor assembly to act on the square tongue transmission device, so that the square tongue of the square tongue assembly protrudes or retracts into the lock body to achieve the purpose of locking or unlocking. In order to achieve the purpose of mechanical unlocking, electronic locks are generally equipped with There is a mechanical unlocking device, and the purpose of mechanical unlocking is achieved through a key. However, after the existing electronic lock is unlocked, the square tongue transmission device is still in a state of linkage with the square tongue assembly. At this time, if a key is used for mechanical unlocking, the key’s The rotation needs to drive the square tongue transmission device to rotate to realize the extension and locking of the square tongue. The entire locking process requires a lot of force. Therefore, there is a need for improvement in the existing structure.
