Hereinafter, a preferred embodiment of the present invention will be described in more detail as a preferred embodiment with reference to the accompanying drawings.

1 is an overall configuration diagram of a door lock device according to an embodiment of the present invention, Figure 2 is a perspective view illustrating a structure of the door lock device according to an embodiment of the present invention.

The door lock device of the present invention is a device suitable for using the smart stick of the Republic of Korea Utility Model Application No. 2003-9850, the applicant of the present application.

1 and 2, the smart stick 10 is made of a plastic body in the form of a key consisting of a knob 11 and a stick 13, the knob 11 is an integrated circuit device chip (12) is built in the chip mounting portion, the stick 13 is composed of an antenna coil mounting portion in which the antenna coil 14 connected to the chip 12 is embedded.

The door lock device of the present invention is composed of a stick hole unit 30 into which the stick 11 of the smart stick 10 is inserted, and a control unit 50 electrically connected to the stick hole unit 30.

The stick hole unit 30 is formed with a stick hole 31 into which the stick 11 of the smart stick 10 is inserted, and a sensor for detecting the stick 11 inserted into the stick hole 31. And an induction coil 14 which communicates data by electromagnetic induction to the antenna coil 14 and simultaneously transmits a high frequency current to form an electromagnetic field for powering the chip 12 of the smart stick 10. It is provided so that the hole 31 may be enclosed. In this case, it is sufficient that the high frequency adopts a proximity type of ISO / IEC 14443 standard having a transmission frequency of 13.56 mHz and an approaching distance of 10 to 20 cm.

The stick hole 31 is made to conform to the shape of the stick 13, and the sensor is an open type push switch 34 that is pushed and switched on by the contact pressure of the stick.

The control unit 50 is enabled by receiving power according to the switch-on of the push switch 34 to enable the coil 14 to supply a current for power supply of the smart stick 10 to the coil 14. It is configured to process the data transmitted and received with the antenna coil 14 to operate the door lock actuator 62.

The power source may be a battery 72 power source, and an external power input terminal 74 for charging the battery 72 is provided.

The door lock actuator 62 may be a motor or a cylinder for locking or unlocking the door lock.

In addition to the door lock actuator 62, an error display LED 64 for displaying an operation error when the smart stick 10 is inserted, a low voltage display LED 66 for displaying a battery charge state, is provided at an output end of the control unit 50. The normal operation display LED 68 indicating that the transaction operation is normal when the smart stick 10 is inserted, a buzzer 69 for generating an operation sound when the smart stick 10 is inserted, and the like may be provided.

The assembly structure of the above-described configuration of the present invention can be illustrated as shown in FIG. Referring to FIG. 2, the coil 36 is wound in a coil-embedded annular body 362 and fastened by a stick hole unit body 312 and threads 314 and 364. The coil 36 and the push switch 34 are connected by connectors CN1 and CN2 and electrically connected to the control unit. [0027] Reference numeral CN3 in the drawing denotes the control unit and the actuator 62, and various LEDs 64,66, 68), the buzzer 69 and the like.

Referring to the effect of the present invention configured as described above are as follows.

When the smart switch 10 is inserted into the stick hole 31 and the push switch 34 used as a sensor is pressed, the push switch 34 is switched on so that a DC main power supply from the battery 72 is applied to the push switch 34. It is supplied to the control unit 50 through the contact point and at this moment the high frequency signal current flows into the coil 36 to activate the chip 12 through the antenna coil 14 of the smart stick 10. Accordingly, the unique ID stored in the chip 12 is communicated with each other by an electromagnetic coupling induced by the coil 36 wrapping the stick 13 through the antenna coil 14 of the stick 13. If the ID does not differ from each other in communication with the smart stick 10, the door 50 operates the door lock actuator 62 to open and close the door lock.

Subsequently, when the user pulls out the smart stick 10 from the stick hole 31, the power supplied to the control unit 50 through the push switch 34 is cut off and power consumption is stopped.

In the current technical level related to this application, the time given for completing the transaction of the smart stick is very short, 200 mS or less, whereas the user pushes the push switch 34 only by inserting and removing the smart stick 10 into the stick hole 31. The time that power is supplied to the control unit 50 will be much longer than the 200mS, so that all the operations for the door locking will be sufficient to complete.

Of course, when such an operation error occurs, the error display LED 64 is turned on so that it can be operated again. The lighting time of the error indication LED 64 and the other LEDs 66, 68, and 69 may be delayed by capacitor elements provided in the control unit 50.

On the other hand, the door lock device of the present invention can be used not only for the smart stick 10, but also in the case of a conventional contactless smart card having a chip and an antenna coil. That is, the groove into which the card is inserted is configured in a slit form differently from the stick hole 31, and the coil 36 may be attached to one side of the groove into which the card is inserted, and on the card into which the push switch 34 is inserted. Of course, the structure such as being pressed by the same will be the same as the case of the smart stick in the operation if all the same.

As described above, the door lock device of the present invention uses power only for a moment using a non-contact smart stick or smart card, which has a high processing speed, and thus consumes very little power so that it can be used for a long time even after being used as a battery. Almost no work is required, and there is no need to connect a separate power line as the battery is used.
