More specifically, an electromagnet and an electronic circuit part are added to a card key type lock device that has been used conventionally mechanically, and an electronic circuit part is added to a card key to apply both a mechanical authentication method and an electronic authentication method. It relates to a mechanical hybrid locking device.

In general, a lock is widely used in homes, businesses and shops for the method and security. However, in recent years, as the technique of criminals is advanced and the safety of the mechanical lock is threatened, it is being replaced with a digital lock. There are many authentication methods in such a mechanical lock and a digital lock. Recently, a method of improving security, such as a password input through a keypad, an authentication method, an authentication method using a button key, an authentication method using a card key, and an authentication method using a fingerprint, is frequently used.

Among them, the authentication method using a card key may be implemented by a mechanical lock device, and in such a device, the authentication method is released through a mechanical authentication method using a magnet.

1 is a view of a mechanical locking device using magnets currently in use.

The mechanical locking device using a magnet includes a card key 110 for unlocking and a card key input unit 120 into which the card key 110 is inserted. In the card key 110 and the card key input unit 120, magnets 140 having magnetisms of N and S poles used for unlocking and ruledness are arranged, and at least one non-polar part 130 having no magnetism is arranged. .

As shown in FIG. 1, the card key 110 and the card key input unit 120 are arranged such that each of the magnets 140 and each of the non-polar parts 130 correspond one-to-one. That is, the magnet 140 is positioned in place of the card key input unit 120 corresponding to the portion where the magnet 140 is located in the card key 110. In addition, the non-polar part 130 is positioned at the position of the card key input part 120 corresponding to the portion where the non-polar part 130 is positioned in the card key 110.

2A is a side view for explaining a method of operating a mechanical locking device using a magnet.

2A is a side view before the card key 110 is inserted into the card key input unit 120.

The card key 110 includes a magnet 140. The magnet 140 is a permanent magnet. The polarity of one of the N pole 210 and the S pole 220 is directed upward, and the other polarity is downward. It is inserted to face.

The card key input unit 120 includes a slot accommodating portion 230, an inner magnet 240, and a lock outer portion 250.

The slot accommodating part 230 is a part into which the card key 110 is inserted and moves back and forth within the card key input part 120. Grooves are recessed in the upper portion of the slot accommodating portion 230, and the inner magnets 240 are usually hung in the grooves so that they cannot be moved back and forth.

The inner magnet 240 is positioned above the slot accommodating portion 230 and is located in a one-to-one correspondence with the magnet 140 of the legitimate card key 110 used for unlocking. In addition, the same polarity as that set upward from the card key 110 is set to face. That is, when the N pole 210 is set upward in the card key 110, the inner magnet 240 of the one-to-one correspondence seat is set so that the N pole 210 faces downward. On the contrary, if the S-pole 220 is set upward in the card key 110, the inner magnet 240 of the one-to-one correspondence seat is set so that the S-pole 220 faces downward.

The outer groove 250 has a groove in which the inner magnet 240 can move. The groove is large enough to allow the inner magnet 240 to be fully inserted.

When the card key 110 is inserted in the situation of Fig. 2A, it becomes the same as Fig. 2B. In FIG. 2A, since the magnet 140 and the inner magnet 240 inserted into the card key 110 are set to face the same polarity, when the card key 110 is inserted, between the magnet 140 and the inner magnet 240. The repulsive force acts on the inner magnet 240, and thus the inner magnet 240 floats into the empty space of the lock outer part 250. When the inner magnet 240 floats into the empty space of the lock outer part 250, the slot accommodating part 230 may move back and forth.

When the slot accommodating portion 230 is pushed backward, the situation is as shown in Fig. 2C, and the mechanical locking device using the magnet is released.

2B is a plan view for explaining a method of operating a mechanical locking device using a magnet.

Payment 230 is pushed back, as shown in FIG. 2E. Here, the slot accommodating part 230 has protrusions 250 on both sides thereof, so that the slot accommodating part 230 is pushed only to a part where the protruding part is caught inside the lock outer part 250.

As the slot housing 230 is pushed backward, the spring 260 connected to the slot housing 230 and the lock outer portion 250 is extended, and the mechanical locking device is released. When the mechanical lock is released and the card key 110 is removed, the extended spring 260 is reduced again to return to its original state, and the inner magnet 240 floating by the repulsive force between the magnets is disposed in the slot accommodating portion 230. The slot accommodating portion 230 falls back into the groove and serves to support the module not to be pushed. That is, it is in the locked state as shown in Fig. 2A.

The mechanical lock device released through the above process has the polarities of the card key input unit and the magnet used in the card key in advance, so it is impossible to change the arrangement of the magnets. If the card key is lost, the card key input unit is secured. There is a problem that needs to be replaced. In addition, there is a security problem that a duplicate key can be generated when the magnetization detection sensor is pushed into the slot into which the card key is inserted to obtain the position and polarity information of the internal magnet.
