Passive intelligent lock

Abstract

The invention discloses a passive intelligent lock. The passive intelligent lock comprises a lock body and a key. A U-shaped lock beam and a spring bolt used for locking or unlocking the lock beam are arranged in the lock body in a sliding manner. A key insertion hole is formed in the bottom of the lock body. A plug is correspondingly arranged at one end of the key. A power supply battery is arranged in the key. The U-shaped lock beam is connected with a reset device enabling the U-shaped lock beam to move upwards. A lock cylinder with a control mainboard is arranged in the lock body and connected with the spring bolt through a titanium alloy memory wire. When the key is inserted into or pulled out of the key insertion hole, the key is powered on or powered off to the titanium alloy memory wire through the lock cylinder, the titanium alloy memory wire is powered on to shrink to pull the spring bolt to leave the U-shaped lock beam, and the titanium alloy memory wire is powered off to recover to control the spring bolt to move towards one side of the U-shaped lock beam. According to the passive intelligent lock, the titanium alloy memory wire which is a novel material is adopted as a driving material in a lock cylinder module, the lock is unlocked or locked through powering-on shrinkage and powering-off recovery of the physical characteristics of the titanium alloy memory wire, the service life is longer, the application range is wider, and the safety performance is higher.

Description

technical field [0001] The invention relates to a lock, in particular to a passive intelligent lock, which belongs to the technical field of electronic locks. Background technique [0002] An electronic lock is an electronic lock that controls the operation of a circuit or a chip (access control system) through password input or signal input, thereby controlling the closing of a mechanical switch and completing the tasks of unlocking and locking. This type of electronic lock generally requires a paired electronic key to be turned on. At present, passive electronic locks are an emerging technology in the world, and there are not many companies involved in them. However, its electronic and mechanical double encryption and idling lock cylinder technology stand out. [0003] The motors used in traditional passive locks have short service life and are more limited by the environment. For example, when the motor is in an environment below -20°C, the lubricating fluid on the motor...

Problems solved by technology

[0003] The motors used in traditional passive locks have short service life and are more limited by the environment. For example, when the motor is in an environment below -20°C, the lubricating fluid on the motor shaft will solidify, making it difficult to work.
