Fingerprint padlock

Abstract

The invention relates to the technical field of padlocks, in particular to a fingerprint padlock. The fingerprint padlock comprises an unequal-arm U-shaped lock ring, a lock shell, a support shaft, arotary plunger latch, a clamp spring, a power unlocking device, a driving controller and a fingerprint identifier, wherein a guiding lock cavity and a lock hole are arranged in the lock shell; the rotary plunger latch comprises a shaft sleeve part and an abutting-pressing latch arm, a lock opening is arranged in the side wall of the guiding lock cavity, a locking wedge opening is arranged in a long arm portion of the unequal-arm U-shaped locking ring, and in the locking state, the abutting-pressing latch arm abuts against the locking wedge opening; the clamping spring is used for driving the abutting-pressing latch arm to be close to the lock opening; the power unlocking device is used for driving the abutting-pressing latch arm to be away from the lock opening. According to the fingerprint padlock, the fingerprint identifier is used as an identification device for opening and closing the lock, the user only needs to carry out fingerprint verification by using fingers, so that the locking and unlocking operations can be carried out, and meanwhile, under the locking state, the abutting-pressing latch arm stably locks the unequal-arm U-shaped locking ring in the lock shell, the locking force of the lock and the safety of the lock are greatly improved, and the service life of the electric component in the lock shell is prolonged.

Description

technical field [0001] The invention relates to the technical field of padlocks, in particular to a fingerprint padlock. Background technique [0002] Padlocks are one of the most traditional and oldest types of locks. Traditional padlocks are usually composed of main components such as a lock body, a lock cylinder, a lock rod, and a key. The key is used to control the lock core to rotate in the lock body to control the lock rod to be locked into the lock hole or to be pulled out from the lock hole, thereby Realize the locking or unlocking of the padlock; however, the traditional padlock has the following defects: 1, the key is easy to lose, and it is easy to forget the key and the lock cannot be unlocked; 2, the key is easy to copy, and it is relatively unsafe to use. [0003] With the continuous improvement and development of technology, the intelligent fingerprint padlock with human fingerprint as the identification carrier and means is being continuously improved, and h...

Traditional padlocks are usually composed of main components such as a lock body, a lock cylinder, a lock rod, and a key. The key is used to control the lock core to rotate in the lock body to control the lock rod to be locked into the lock hole or to be pulled out from the lock hole, thereby Realize the locking or unlocking of padlocks; however, the traditional padlocks have the following defects: 1. The key is easy to lose, and it is easy to forget the key so that the lock cannot be unlocked; 2. The key is easy to copy, and it is not safe to use

[0003] With the continuous improvement and development of technology, the intelligent fingerprint padlock with human fingerprint as the identification carrier and means is being continuously improved, and has made important contributions in the fields of security and anti-theft, but it still has certain defects such as: 1. Its internal The electronically controlled lock cylinder uses a driving device such as a motor to drive the lock bolt to move to realize the unlocking or locking action. In the locked state, the locking force of the locking structure of the existing lock cylinder is not high. Under the action of force, it is easy to be pried open and cannot achieve a stable locking effect; 2. Simply relying on the electronically controlled lock cylinder to unlock the lock will also cause problems such as motor failure or damage to other electrical components. Unable to continue to use, which brings inconvenience to users; 3. There are too many internal locking and transmission parts, and the structure is relatively complicated, resulting in the inability to reduce the volume and high production costs
