Locking apparatus using dual power generation interlocking with a smartphone {Locking apparatus with dual power generation communicating with smart phone}

The present invention relates to a locking device using dual power generation interlocking with a smart phone, and more particularly, to a locking device that locks a locking object such as a drawer, a safe, or a door using induction power generated when a smart key is inserted into a locking device. In addition to performing authentication on the key, when authentication is successful, the actuator is operated with the generated power generated through the physical power generation by the insertion so that the lock is unlocked by the key structure of the smart key, but with a smartphone It relates to a locking device using dual power generation so that the authentication key of the smart key and the locking device can be changed using NFC communication.

A locking device that is unlocked only by an authenticated key is installed and used in order to restrict the access of the user's goods or an outsider, such as a storage box or a door for storing the user's goods.

In the past, such locking devices depend only on the physical structure of the key, and are configured to operate so that the lock is unlocked only when the physical structure of the key and the key bundle configured in the locking device into which the key is inserted are the same. Since the lock is easily unlocked only by duplication, there is a problem in that security is significantly lowered.

In addition, since only one locking device is installed in the case of a door used by multiple people, there is a problem that a plurality of keys having different physical structures cannot be applied to these locking devices, as well as a key capable of unlocking the locking device is lost. When exposed to a security risk, there is a problem that the entire lock has to be replaced.

A smart method that recently improved this and configures an IC-based authentication module in the key to unlock the lock, and unlocks the lock when the authentication information stored in the authentication module is successfully authenticated through wired/wireless communication with the authentication module in the lock. Locks are emerging.

Since such a smart lock operates irrespective of the physical key structure, it can be applied to a lock target used by a large number of people, such as an entrance door.

In addition, when it is difficult to install the smart lock device for each locker to supply external power to each lock device, or when the smart lock device is placed in an environment where it is difficult to supply external power to the smart lock device, the smart lock device Since a replaceable battery must be connected to the smart lock for each lock and used, when operating a number of smart locks, the battery purchase cost is high, which increases the maintenance cost. there is a problem.

Furthermore, in the case of such a smart lock, the authentication structure between the smart key and the lock is complicated, and it is difficult to change such authentication, or separate dedicated equipment is required. There is a problem that causes a lot of trouble.
