A digital lock cylinder

Abstract

The invention discloses a digital lock core. The invention realizes that when a key is inserted into the lock hole, the system is powered on, the identification control circuit starts to work, and the electronic locking device is controlled to complete the function of the electronic lock when the key is inserted into the lock hole. Pull out the lock hole, and the system will power off after completing the corresponding operation. Therefore, compared with the traditional electronic lock, the present invention only connects to the power for the necessary time, and cuts off the power when it is not needed, so that the electronic lock consumes power The power consumption is greatly reduced, the power supply mode is more reasonable, and the battery can be directly used for power supply; the power-taking switch device and the electronic locking device of the present invention can be set very small, and are directly installed in the lock cylinder or the lock cylinder, so no new installation is required. Design and manufacture, just can use traditional mechanical type lock cylinder as the lock cylinder element of the present invention, manufacturing cost is greatly reduced, and structure is also smaller.

Description

technical field [0001] The invention relates to a lockset, in particular to a digital lock cylinder in a door lock. Background technique [0002] Locks play an important role in people's daily life and work. A good lock is the guarantee of people's life and property safety. At present, the locks on the market can be mainly divided into mechanical structure and electronic lock structure. The mechanical structure is controlled by the key. Twisting to unlock or close the lock is a relatively common structure, and it is easy to be cracked accordingly, and the anti-theft performance is not ideal. The electronic lock structure mainly realizes the opening and closing of the lock by driving the lock cylinder structure by electromagnetic force, and the principle is usually more complicated. , and the reliability is low, it is easy to respond to power failure or other unexpected situations, so that the lock structure is stuck in a certain action and cannot be used normally, forming a ...

[0002] Locks play an important role in people's daily life and work. A good lock is the guarantee of people's life and property safety. At present, the locks on the market can be mainly divided into mechanical structure and electronic lock structure. The mechanical structure is controlled by the key. Twisting to unlock or close the lock is a relatively common structure, and it is easy to be cracked accordingly, and the anti-theft performance is not ideal. The electronic lock structure mainly realizes the opening and closing of the lock by driving the lock cylinder structure by electromagnetic force, and the principle is usually more complicated. , and the reliability is low, it is easy to respond to power failure or other unexpected situations, so that the lock structure is stuck in a certain action and cannot be used normally, forming a locked situation, which is not convenient for people's normal use

[0003] In view of this, a kind of simple structure, safe and convenient and reliable digital lock has appeared on the market at present. A power-taking switch device and an electronic locking device are installed inside. When the digital key is inserted into the lock cylinder, the control unit can be connected to the digital key through the power-taking switch device, and the password information of the digital chip in the digital key and the original password information in the memory In comparison, by judging whether the password information is consistent, unlocking or locking is realized through the electronic locking device; wherein, the electronic locking device is used to brake the lock cylinder, and when the locking state machine is inserted into an illegal key, the electronic locking device is in the lock state. Between the core and the lock cylinder, the lock cylinder cannot be rotated. When a legal digital key is inserted, the electronic locking device will withdraw from the lock cylinder, so that the lock cylinder can rotate, and then open the lock. This brake is braked by braking the lock body. The structure of the lock cylinder, its electronic locking device is usually a component such as a relay, which is large in size and needs to be installed in the lock body, which makes the structure of the lock body change greatly, and the whole needs to be redesigned and manufactured, which increases the cost and consumes electricity It is also relatively large, and usually needs to be directly connected to the mains for work, especially the pop-up and reset actions of the electronic locking device in the lock body, which consume power, which will increase the burden on the energy consumption of the digital lock
