The present invention relates to a lock release structure of a magnetic door lock device, and more particularly, a storage compartment in which a fixed magnet is installed on an upper portion of the front side, a cover hinged to an upper portion of the rear side of the storage compartment, and a magnetic button insertion groove formed on the front surface thereof; A first torsion spring installed in the hinge portion of the cover, a magnet button hinged to the magnet button insertion groove, and a second torsion spring installed in the magnet button insertion groove. The cover can be easily opened from the storage compartment to further enhance the magnetic performance of the magnetic door lock device, thereby improving the locking performance. Also, the cover can be easily opened from the storage compartment with a small force. It relates to a lock structure of the magnetic door lock device that can be used conveniently.

The magnetic door lock is a lock that prevents the cover from being opened unless a force that is stronger than the magnetic force of the magnet is applied by allowing the cover fixed to the storage compartment to be in close contact with the storage compartment by using the attraction force of the magnet. And in order to prevent the spilled goods, etc., is mainly applied to the ashes or storage boxes of the car with a lot of vibration.

As an example, a conventional magnetic door locking device will be described with reference to FIG. 1, and the cover 120 is hingedly fixed to the upper portion of the storage chamber 110, and the magnet 111 is disposed above the open surface of the storage chamber 110. Is installed, the iron plate 121 is attached to the lower portion of the open surface of the cover 120.

By such a structure, the cover 120 hinged to the storage compartment 110 is to be attached to the magnet 111 of the storage compartment 110, the iron plate 121 attached to the cover 120, The cover 120 is not opened until the cover 120 is opened with a force greater than the magnetic force of the magnet 111.

However, the conventional magnetic door lock device as described above requires more force to open the cover as the magnetic force of the magnet increases, so it is very difficult to open and close the cover with one hand when discarding a cigarette butt in a storage compartment. It was uncomfortable.

In addition, in order to solve such a problem, when the magnetic force of the magnet is weakened, the attraction force of the magnet is weakened, so that the cover is opened too easily from the storage chamber, and the contents of the storage chamber are spilled.

Therefore, the present invention is to solve the problems as described above, to improve the locking performance by reinforcing the magnetic force of the magnetic door lock device, and to facilitate the opening of the cover from the storage compartment with a small force. The object of the present invention is to provide an unlocking structure of a magnetic door lock device that allows a user to easily open the cover as well as a user who is inconvenient for hands.

The object of the present invention is a storage compartment in which a fixed magnet is installed on an upper portion of the front surface, a cover which is hinged to an upper portion of the rear surface of the storage chamber, and a magnetic button insertion groove is formed on the front surface, a first torsion spring installed on the hinge portion of the cover, It is achieved by the unlocking structure of the magnetic door lock device consisting of a magnet button hinged to the button insertion groove, and a second torsion spring installed in the magnet button insertion groove.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the subject innovation.

As shown in FIGS. 2 and 4, the unlocking structure of the magnetic door locking device according to the present invention includes a storage compartment 10 in which a fixed magnet 11 is installed in an upper portion of the front surface, and a rear surface of the storage compartment 10. A cover 20 having a magnet button insertion groove 21 formed on the front is coupled to the upper side by a left and right hinge shaft 22.

The hinge shaft 22 of the cover 20 is provided with a first torsion spring 23 for applying a force upwardly to the cover 20 and both inner surfaces of the magnet button insertion groove 21 of the cover 20. The guide shaft 24 is formed to protrude.

" 형태의 원 호홈(25a)이 양측 면에 형성된 자석 버튼(25)이 힌지 결합된다.The magnetic button insertion groove 21 has a high front and a low rear "

"A circular arc groove 25a of the shape is formed on both sides of the magnet button 25 is hinged.

The guide shaft 24 of the magnet button insertion groove 21 is provided with a second torsion spring 26 for applying a force upwardly to the rear end of the magnet button 25.

Here, the magnet button 25 and the fixed magnet 11 installed in the storage chamber 10 is installed so that different polarities are located on the opposite surface.

Hereinafter, the operation of the unlocking structure according to the present invention configured as described above will be described with reference to FIGS. 5 and 5a.

First, when the cover 20 of the storage compartment 10 is closed, the magnet button 25 hinged to the cover 20 by pressing the cover 20 is fixed to the fixed magnet 11 installed in the storage compartment 10. When the cover 20 is in close contact, the cover 20 is tightly fixed to the storage chamber 10 by an attractive force acting between the magnet button 25 and the fixed magnet 11.

Subsequently, when the cover 20 of the storage chamber 10 is to be opened, the magnetic button 11 is moved to the rear so that the magnetic button is along the arc grooves 25a formed on both sides of the magnetic button 11. The rear end of the magnet button 25 is lifted up by the second torsion spring 26 installed at the guide shaft 24 of the cover 20 while the 25 is moved backwards.

At this time, the tip portion of the magnet button 25 is still in contact with the fixed magnet 11 of the storage chamber 10. However, in this state, only a part of the magnet button 25 is in contact with the fixed magnet 11, so that the cover 20 is pushed up with a slight force by the first torsion spring 23. The cover 20 is completely open.

According to the present invention as described above, the cover can be easily opened from the storage compartment with a small force in the magnetic door lock device to further enhance the magnetic force of the magnetic door lock device to improve the locking performance.

In addition, since the cover can be easily opened from the storage compartment even with a small force, the cover can be easily opened by a user as well as a user who is inconvenient for hands.
