Portions denoted by like reference numerals denote like elements throughout the specification.

Hereinafter, with reference to the accompanying drawings according to an embodiment of the present invention 1 to 8 will be described in more detail. In the drawings, the same reference numerals are given to components that perform the same function.

1 and 2 are views showing the configuration of a digital door lock according to an embodiment of the present invention.

1 and 2, the digital door lock 100 of the present invention is largely divided into an outdoor operation unit 110, an indoor operation unit 120, and a lock case unit 130.

The indoor control unit 120 is installed on the inner surface of the door, the open / close button 122, the inner handle 124 to open the door from the inside, the manual lever to release the dead pin manually ( Thumb turn 126 and the human body sensor 128 is installed. In addition, the indoor control unit 120 has a known selection button 125 formed to select a manual mode and an automatic mode by an artificial operation.

For example, in the automatic mode, the dead pin can be opened and closed through an external key input, an internal open / close button or a manual lever. When the selection switch is selected in the manual mode, the motor described below is not operated, and the dead pin can be released only through the manual lever.

On the other hand, the indoor control unit 120 is provided with a controller 190 for electrically controlling the operation of each component, a detailed description of this portion will be described later.

The digital door lock of the present invention has a light emitting part 119 in the indoor handle so that the user can identify whether the digital door lock is locked or unlocked even in a room (living room or a room) far from the door. The light emitting part is composed of LEDs emitting light in blue and red (different colors), and the light emitting part is controlled by the controller 190. For example, when the digital door lock is locked, the light emitting part shines in blue at intervals of several seconds, and when the door lock is unlocked, the light shines in red (warning indication). It can be identified whether the lock.

The outdoor operation unit 110 is installed on the outer surface of the door, a plurality of keypads 112 for inputting a password, and an external handle 114 for opening the door from the outside is installed. Here, the connecting members 124a and 114a of the inner / outer handles 124 and 114 are fitted with fitting pieces 124a 'and 114a' fitted to the rotating body 150 of the lock case 130, and the manual lever The shaft 126a of 126 is connected to the operating gear of the lock case 130. (See Figures 1 and 3A)

3A to 3B, the lock case 130 includes a dead pin 132, a prepin 134, a gear assembly 140, and a clutch means 150. The dead pin 132 is moved back and forth by the operating rod 146 mounted on the fifth gear 145 of the gear assembly 140. The gear assembly 140 has first to fifth gears (only some of the gears are shown in FIG. 5) that are sequentially connected to reduce the rotational force of the motor M to increase torque. The motor M is connected to the first gear 141, and the fifth gear 145 is connected to an operation gear 148 connected to the shaft 126a of the manual lever 126.

 In a conventional digital door lock, it is common to set the gear reduction ratio low so that the manual lever can be easily turned with little force to release the dead pin. However, in the present invention, the gear reduction ratio of the gear assembly 140 is set high so that the user cannot turn the manual lever with a general force. In addition, in order to turn the manual lever 126, a clutch means 160 is further provided to separate the motor M and the gear assembly 140 so that the gear assembly 140 is in a no-load state. The clutch means 160 is actuated by the rotation of the interior handle 124. The clutch means will be described below.

As such, in the digital door lock 100 of the present invention, after the interior handle 124 is rotated to make the gear assembly 140 in a no-load state, the manual lever 126 should be rotated, but the dead pin 132 Determination is possible. In other words, in order to release the door lock (dead pin) using the manual lever 126, first, the interior handle 124 is rotated with one hand, and then the manual lever 126 is rotated with the other hand. . This may be inconvenient for the user, but on the contrary, there is an advantage in that the external intruder cannot easily operate the manual lever.

Meanwhile, the prepin 134 is moved back and forth by turning the indoor / outdoor handles 124 and 114 to open and close the door. The fitting pieces 124a 'and 114a' of the indoor / outdoor handle are coupled to the rotating body 50 of the lock case 130, and the rotating body 150 is a slider 152. And a slider 152 is connected to a link 154 connected to the prepin 134. That is, when the knob 124 is rotated, the rotor 150 rotates, the slider 152 is moved by the rotation of the rotor 150, and the link 154 is moved by the movement of the slider 152. While rotating the prepin 134 to the rear.

Referring to Figures 3a to 4b will be described the clutch means which is the most important component in the present invention.

The clutch means 160 includes a clutch gear 162, a spring 164, and a clutch plate 166. The clutch gear 162 is installed between the first gear 141 and the second gear 142 (see FIGS. 3B and 5). The rotational force of the motor M is determined by the first gear 141. The clutch gear 162 is transmitted to the second gear 142. The spring 164 is installed between the clutch gear 162 and the first gear 151. The spring 164 provides an elastic force to separate the clutch gear 162 from the first gear 141. The clutch plate 166 controls the clutch gear 162 to be separated from the first gear 141 by the spring 164. The clutch plate 166 is slidably installed outside the case 140a of the gear assembly 140 and is connected to the slider 152. The clutch plate 166 is moved together with the slider 152. In other words, when the inner handle 124 is turned, the prepin 134 is released and the clutch plate 166 is also moved.

The clutch plate 166 has a first portion 166a and a second portion 166b. As shown in FIGS. 3A and 3B, when the first portion 166a is positioned on the clutch gear 162 (clutched / loaded state), the clutch is driven by the first portion 166a. The gear 162 is pressed to maintain the state connected to the first gear 141. 4A and 4B, when the second portion 166b is positioned on the clutch gear 162 (the clutch is dropped / no load state), the clutch gear 162 is connected to the spring. 164 is separated from the first gear 141.

Next, referring to FIGS. 5 and 6, when the manual lever 126 is rotated in that state, the operating gear 148 connected to the shaft 126a of the manual lever 126 is rotated, and the operating gear 148 is rotated. The connected fifth gear 145 and the operating rod 146 are rotated. The dead pin 132 is moved rearward by the operating rod 146.

As such, in the digital door lock 100 of the present invention, after the interior handle 124 is rotated to make the gear assembly 140 in a no-load state, the manual lever 126 should be rotated, but the dead pin 132 Determination is possible.

In addition, the indoor manipulation unit 120 is provided with a human body sensor 128. The human body sensor 128 detects whether the subject that rotates the indoor handle and the manual lever is a person. The controller 190 drives the solenoid valve 180 only when the main body is a human, thereby lowering the stopper 182. When the main body that rotates the indoor handle 124 and the manual lever 126 is a mechanical device, the stopper 182 does not allow the dead pin 132 to be released. Therefore, even if the external intruder puts a mechanical device into the milk inlet to operate the indoor handle and the manual lever, the dead body 132 may not be finally detected by the human body sensor 128. It cannot be resolved. The stopper 182 blocks the release of the dead pin only in the manual mode (when the user selects the manual mode therein).

As such, the digital door lock 100 of the present invention has a double / triple locking function so that the door cannot be opened even if an outsider operates the inside operation unit using a mechanical device from the outside.

FIG. 7 is a view illustrating a connection body of an inner / outer handle, and second and first limit switches 127 and 117 are installed at the connection bodies 124a and 114a of the inner / outer handle 124.114. The limit switches 127 and 117 check which knob is turned and inform the control unit 190. For example, when the manual lever 126 is rotated while the external knob 114 is turned, the controller recognizes an intrusion of an outsider and responds appropriately.

See also FIG. 8. In particular, when the outer handle 114 is rotated in the state in which the dead pin 132 is released (only the door is closed), the first limit switch 117 detects this, and the detection signal from the first limit switch 117 Receiving the control unit 190 locks the dead pin 132 by operating the motor. This safety function can prevent external intrusion that may occur when the user goes out without locking the door lock.

8 is a block diagram showing the configuration of a digital door lock according to the present invention. Referring to FIG. 8, the controller 190 controls the motor M to open and close the dead pin 132. In addition, the controller 190 may control the opening and closing of the dead pin 132 by controlling the solenoid valve 180. That is, the controller 190 controls the solenoid valve 180 to prevent the dead pin 132 from moving backward by the stopper 182 when the human body is not detected by the human body sensor 128 in the manual mode. do. When the human body is detected by the human body sensor 128, the stopper 182 is moved by operating the solenoid valve 180 so that the dead pin 132 is moved backward.

In the above, the configuration and operation of the digital door lock according to the present invention has been shown in accordance with the above description and drawings, but this is only an example, and various changes and modifications are possible within the scope without departing from the spirit of the present invention. Of course.

As described in detail above, even if the door lock is operated through the milk inlet or the like outside the door, it is possible to prevent the door lock from being released. In addition, in the present invention, in order to release the door lock (dead pin) using the manual lever, since the first step is to rotate the interior handle with one hand, then rotate the manual lever with the other hand, the external intruder is manual The advantage is that the lever is not easily operated. In addition, in the manual mode, since the dead pin can be released only when a person operates the door lock indoors, the door lock cannot be released even if the indoor operation unit is operated by any method from the outside. There is this.
