1 is an internal cross-sectional view of the inner body portion 100 of the door lock device according to the present invention. As shown in FIG. 1, the inner body 100 includes an inner frame 105, a main board 110, an emergency control board 120, a drive mechanism module 130, a dead bolt 160, And a door lock detection sensor 170. And one side of the inner body portion 100 is formed with a slot for the dead bolt 160 to advance and retreat. The main board 110 and the emergency control board 120 are fixed to the inner frame 105 by screws or the like.

5 is a control system diagram of the door locking device according to an embodiment of the present invention. The main board 110 includes a main microprocessor 1 and a memory 6. The emergency control board 120 includes an emergency microprocessor 20, a motor driver 21, and a relay 22.

On the other hand, the inner body portion 110 has an internal button 7 for the user to manually lock or unlock the door in the room, a sensor 5 for detecting the closed state of the door, and the user ID The apparatus further includes an ID input button 8 for inputting an ID, an ID delete button 9 for deleting an recorded ID, an ultra-high frequency receiver 3, and a long wave transmitter 4. The internal button 7, the sensor 5, the ID input button 8, the ID delete button 9, the microwave receiver 3, and the long wave transmitter 4 are connected to the main microprocessor 1. It is connected to send and receive signals.

The drive mechanism module 130 is connected to the motor 135, the output shaft of the motor 135, and the second bevel gear (131a) to the first bevel gear 131a and the first bevel gear 131a. And a rotating arm 133 rotatably connected to the axis of the secondary bevel gear 131b. The dead bolt 160 has a guide slot 161 is formed, the groove is formed of a "-" shaped to accommodate one end side of the rotary arm 133 is formed. As illustrated in FIG. 3, the guide pin 166 penetrates the guide slot 161 to guide the dead bolt 160.

The outer body portion 200 includes an outer frame 205, an antenna portion 220, an outer button 230, an emergency board electrode 250, and an emergency battery 260. The antenna unit 220 includes a microwave antenna 33, a long wave antenna 34, and a communication start button 40. The microwave antenna 33 is configured to transmit the microwaves received by the microwave receiver 3 of the inner body portion 100, and the long wave antenna 34 from the long wave transmitter 4 of the inner body portion 100. It receives a signal and transmits a long wave. On the other hand, the lower portion of the outer body portion 200 is provided with an insertion hole (not shown) for inserting the emergency key in an emergency. And the outer body portion 200 may be provided with an external call button 32 to call from the outside. According to the present invention, only when the communication start button 40 is pressed, the long wave is transmitted through the long wave antenna 34 to start communication with the wireless card 1200. The antenna unit 220 may be disposed inside the door instead of the outer body unit 200. In addition, the communication start button 40 may also be replaced by another input means such as an input sensor, for example, an infrared sensor, which allows a user to input various types of inputs.

The key means used for the door lock according to the present embodiment is a portable wireless card capable of wireless communication with the door lock. As shown in FIG. 6, the wireless card 1200 includes a card-side microprocessor 1201, a long wave receiver 1202, a long wave receiving antenna 1203, a microwave transmitter 1204, and a microwave transmitting antenna ( 1205).

Hereinafter, the operation of the door locking device according to the present embodiment will be described.

When no signal is received from the wireless card 1200 or no control is performed, the main microprocessor 1 sends a door lock command to the motor 135 so that the dead bolt 160 protrudes out of the door. The door lock state is maintained by engaging the groove of the door frame formed at the position corresponding to the dead bolt 160.

When the user holding the wireless card 1200 enters a predetermined range while the user has started to transmit the long wave through the long wave transmitter 4 by pressing the communication start button 40, the long wave antenna 34 transmits it. The long wave receiver 1202 receives the received long wave through the long wave receiving antenna 1203 of the wireless card 1200, and the internal power of the wireless card 1200 is turned on and transmits a signal including the ID code of the wireless card. 1205). When the signal is received via the microwave receiving antenna 33, the ID code included in the signal is decoded and it is determined whether there is a match among the stored ID codes. The user inputs the ID of the previously authenticated person through the ID input button 8 and records it in the memory 6.

If there is a matching ID code, it is determined that the user is a legitimate person and a door unlocking command is sent to the motor 135. When the motor 135 is driven, the first bevel gear 131a connected to the output shaft of the motor 135 is rotated, and has a rotation shaft perpendicular to the axis of the first bevel gear 131a and the first bevel gear 131a. The second bevel gear 131b meshed with the bevel gear 131a also rotates. The rotation arm 133 connected to the shaft of the second bevel gear 131b is rotated to a predetermined range by the rotation of the second bevel gear 131b, and the rotation arm 133 is a dead bolt 160. Since it is caught in the groove, the dead bolt 160 is retracted into the door in accordance with the rotation of the rotary arm 133. The dead bolt 160 is guided and slides by the guide pin 166 passing through the guide slot 161. When the dead bolt 160 retreats inside the door, engagement with the groove formed in the door frame is released, and the door lock is released.

On the other hand, when the user holding the wireless card 1200 closes the door opened and is separated from the door, when the operation of transmitting the microwave containing the ID code is terminated, the main microprocessor 1 sends a door lock command. In response to this command, the motor 135 is driven in a direction opposite to the driving direction when the door is unlocked. The bevel gear 131 connected to the output shaft of the motor 135 rotates in the opposite direction to the above-described door unlocking process, and the dead bolt 160, which has been retracted into the door, slides in the direction protruding to the outside of the door. Done.

The drive mechanism module 130 further includes a first sensor 134a and a second sensor 134b that detect the position of the dead bolt 160 to detect the door locking and unlocking state. The first sensor 134a detects that the door is locked, and the second sensor 134b detects that the door is unlocked. The results detected by the sensors 134a and 134b are reported to the main microprocessor 1, so that the main microprocessor 1 grasps the state of the door. In FIG. 2, the locked state or the unlocked state of the door is detected by the position of the dead bolt, but the locked state and the unlocked state of the door may be detected by detecting the positions of the bevel gears 131a and 131b.

The inner frame 170 of the door locking device according to the present embodiment is provided with a door closing detection sensor 170 for detecting a closed state of the door. As the door closing detection sensor 170, a magnetic sensor is mainly used. A magnet is installed in the door frame at a position corresponding to the door closing detection sensor 170 and detects whether the door is closed with the magnetic sensor.

In the state in which the communication start button 40 is not pressed, the long wave is not transmitted through the long wave antenna 34, so even if the user roams around the door, the door is locked and is not unlocked. Thus, the inconveniences of the prior art described above are also eliminated.

Although the present invention has been described with respect to the door lock device for transmitting the long wave from the door lock device and receiving the ultra-short wave from the wireless card side receiving the same, performing the user authentication to lock the door or release the lock state. The scope of the right extends to any door lock that locks or unlocks the door in any form. In addition, the present invention is not limited to the above-described embodiment is determined by the appended claims.

According to the present invention, wireless communication is initiated only when the communication start button is pressed, and the door is locked or released by such radio communication, so that the user repeats the door locking operation or the unlocking operation when the user roams around the door. By not doing so, a convenient effect is provided.
