The electronic control circuit is operated by electronic circuits and sensors formed on the PCB 140 (FIG. 4), and has a key input readout unit for decrypting a signal input through the keys of the outside housing 60. This drives the motor 126 in the direction of reconstruction when the key input signal matches the preset code. Instead of key input, an RF card decryption unit for decrypting a signal of an RF card, a fingerprint decryption unit for decrypting a fingerprint, or a wireless communication decryption unit for receiving and decrypting a wireless signal from a remote location are installed and the signal of such a decryption unit is determined in advance. Of course, it can also be configured to drive the motor in the direction of reconstruction if matched with the binary code.

The rack gear 124 is engaged with the drive gear 126 coupled to the motor shaft to drive the rack gear 124-1 to linearly move the rack gear 124 according to the rotation of the drive gear, and the driven of the one-touch cam 122. A drive rack gear 124-2 for rotating the gear 127 is formed. An intermediate gear 123 may be provided between the drive rack gear 124-2 and the driven gear 127 to set the rotation ratio and torque.

In addition, a long hole is formed in the rack gear 124 and guided so that the linear movement can be moved only by a predetermined distance by the boss 128.

In addition, a magnet 130 is attached to the rack gear 124 as shown in FIG. 4, and magnetic sensing reed switches are installed at upper and lower and middle points of the moving distance of the rack gear. The first sensor 132 and the upper limit is the second sensor 131, the lower limit is the third sensor 133. The reed switch is an electric switch having an operating characteristic that is turned on or off when the magnetic force is over a certain intensity.

Using the reed switch to position the rack gear reduces the battery power consumption. In the prior art, since the photocoupler is mainly used as a position catching sensor for detecting the position of a rack gear or other driving device, power must always be supplied to the photo coupler. Is generated, so it is relatively power-saving.

Control signals are processed by the control electronics to control the direction and amount of rotation of the motor.

As shown in FIG. 5, when the position of the rack gear 124 is in the position where the first sensor is operated (for example, the on position), the electronic control assembly determines that the dead bolt is open. Such a state can also be displayed on a display panel or the like.

After installation on the door, the power is supplied and the dead bolt is locked with the handle by the first time by manual operation. As shown in Fig. 6, the rack gear 124 is moved to the position where the second sensor 131 is turned on. . At this time, it is recognized that the electronic control circuit is caused by an even handle. If you want to open the dead bolt, move the rack gear by moving the motor to move the rack gear to the first sensor position, and if you want to lock the dead bolt, move the rack gear to the position with the second sensor. do.

When the dead bolt is installed and locked by the left hand handle for the first time after the door is installed in the door, the rack gear 124 is moved to the position where the third sensor 131 is turned on as shown in FIG. At this time, the electronic control circuit recognizes that it is caused by the left-handed handle, and when the dead bolt is opened, the motor is moved to the rack gear to move the rack gear to the first sensor position, and when the dead bolt is to be locked. The rack gear is controlled to move to the position where the third sensor is located.

One-touch cam 122 is coupled to the dead bolt shaft 93 of the mortise lock device serves to move the dead bolt to the locked position or the open position.

The inner handle (110: installed in the position where anyone can open the locking device) inside the door is coupled to the latch drive shaft 92, the latch is opened by turning the inner handle, and at the same time one-touch drive mechanism 121 ) Rotates the one-touch cam 122 to rotate the dead bolt shaft 93 in the opening direction. One-touch drive mechanism 121 has a cam rotating portion formed on both sides so as to rotate the one-touch cam 122, whether the door installed by the left hand handle or the door installed by the rain handle.

So inside the door, you can open the door with one touch even if the dead bolt is locked by turning the inner handle, and if you enter the password by pressing the key button outside the door, if the code is matched, the motor will be driven and the dead bolt will open and the outer handle ( 50), the latch can be opened to open the door.

If the electronic circuit breaks outside the door or forgets the password, the door can be opened with an emergency key. The operating part is the emergency rescue mechanism.

The emergency disengagement mechanism comprises: a dismissal cam 87 for rotating the dead bolt driving shaft 93 of the mortise lock locking device 90; A hawage cam tumbler 86 for rotating the hawage cam 87 to an open position or a locked position; An outer handle 50 coupled to the latch shaft of the mortise lock locking device 90; The haze cam dowel 86 is coupled to the groove 51-1 formed in the shaft 51 of the outer handle 50 and the groove 86-1 formed in the haze cam tumbler 86 by the rotation of the outer handle 50. ) So that the rotation cam is not coupled to the groove 51-1 formed on the shaft 51 of the outer handle and the groove formed on the haul cam tumbler. )Wow; It includes a lock mechanism 70 for moving the latch to a position formed in the groove formed in the outer handle shaft and the groove formed in the lock cam cam, and to return to the position that is not engaged.

The lock mechanism 70 includes a magnetic locking module 70 using a magnet dot card key 71 and a magnetic connecting rod 82 for magnetically coupling the magnetic locking module and the latch 84 to the magnetic locking module. When the 70 is raised, the latch 84 is also raised to be coupled to the groove 51-1 formed in the shaft 51 of the outer handle and the groove 86-1 formed in the hackham cam clamp 86 to rotate the outer handle. After the hacking cam is rotated, and the magnetic locking module 70 is moved to its original position, the latch 84 is attracted by the magnetic force of the magnet 83 formed or attached to the magnet connecting rod 82, and then the original position. The hackle cam is not coupled to the groove 51-1 formed in the shaft 51 of the outer handle and the groove 86-1 formed in the hauling cam tow 86 by returning to the shaft. Will not be rotated.

The clasp 84 and the magnet connecting rod 82 are moved while being supported and guided by the clasp support 85. Then, the magnetic locking module 70 is pushed up by the card key and then returned to its original position by the restoring spring 81. Restoration spring 81 is installed between the latch support 85 and the magnetic locking module 70.

The magnet connecting rod 82 is composed of an iron bar 82 integrally coupled to the magnetic locking module and a magnet 83 integrally coupled to the iron rod 82.

The outer handle 50 is shown in FIG. 8 as shown in FIG. 8 to show the shape of the handle shaft in detail for convenience of description in FIG. 8, but is actually indicated at 50 on the left side of the drawing as in FIG. 1.

After the handle is rotated by a predetermined angle by the handle shaft holding mechanism, the handle is returned to its original position when there is no external force.

The holding mechanism includes a support fixing plate for supporting and fixing the spring hook 64 formed on the inner circumference of the projection 64-1 inserted into the groove 52 formed in the handle and the spring 63 caught by the spring hook on the housing 60. 65, which is fixed to the housing by a piece (66). When the handle 50 is rotated, the spring hanger 64 is rotated. The spring hanger 64-2 is bent on the spring hanger so that the spring is not caught by the spring but also by the fixing protrusion formed on the housing. It cannot be rotated. In addition, the handle shaft 51 is formed with a square groove 51-1 at the center of the shaft, which is a hole for engaging the latch shaft connecting piece 91.

The emergency rescue organization operates as follows.

When the handle 50 is rotated, the hatch driving shaft is rotated to move the latch 96 from the locked position to the open position. Thus, when the door is not locked with a dead bolt, the handle can be opened and closed at will.

When the dead bolt 95 is locked, the door cannot be opened by the handle alone, and the magnetic locking module 70 is operated by inserting the card key 71 to be pushed and moved by the card key. (82) is moved together and the brace (84) magnetically attached to the magnet connecting rod is also moved to the groove (51-1) formed on the shaft 51 of the outer handle and the groove (86) formed in the hackham cam claw 86 -1) It gets stuck. When the handle 50 is turned in this state, the haen cam tumbler 86 is rotated to turn the haen cam and eventually the dead bolt is moved to the open position. At this time, since the latch driving shaft coupled to the handle shaft is rotated as well, the latch is opened and the door lock is opened as a whole.

After the card key is removed, the magnetic lock module returns to its original position and the magnet connecting rod moves together. In addition, when the handle is released and the hands are released, the haen cam tumbler is returned to its original position. In this case, the latch comes to the same position as the magnet connecting rod and is attached to the magnet connecting rod by magnetic force. The handle is separated from the groove (51-1) formed in the) and the groove (86-1) formed in the camouflage cam 86, the handle and the haul-dock is released to move independently. In this state, only the latch can be moved to the open position no matter how much the handle is turned, but the dead bolt cannot be moved.

However, the mortise lock is locked by the dead bolt locking cam coupled to the latch shaft when the handle is rotated in a direction opposite to the opening direction. That is, the dead bolt can be locked by turning the external handle, but not opened. Therefore, in order to open the dead bolt with the external handle, the emergency rescue device using the card key must be operated. Also, as described above, the dead bolt can be opened by the electronic discharging mechanism using the key button.

When the door lock device of the present invention described above is used, even if a failure occurs in the electronic circuit or the battery is consumed and the lock device cannot be opened due to the failure of the rated voltage, the door lock device can be reactivated by operating the emergency rescue mechanism. have.

The battery consumption for operating the electronic lock can be reduced.

Even if the battery voltage is discharged below the operating voltage, the door can be opened by operating the emergency rescue device from the outside.

When the door lock is installed on the door, it is convenient to set left and right for the first time automatically by eliminating the inconvenience of having to set rainwater or left water separately according to the door opening direction.

When the door is open, it can be locked by one touch, and when it is locked, it can be opened by one touch, which is very useful for emergency escape and very convenient for everyday use.
