Description

Digital door lock device {Digital door lock device}

The present invention relates to a digital door lock device, and more particularly to a digital door lock device for locking and unlocking the door.

In general, the digital door lock device is widely used in general home houses or public buildings. Typically, digital door locks are used for entrance doors, bank vaults, and access control devices to restrict access to specific areas. In recent years, a digital door lock device that can lock and unlock a door by linearly moving a dead bolt by operating a motor or a solenoid after authenticating a user through a password input or a fingerprint recognition method has been widely used.

On the other hand, in recent years, attempts to hack digital door lock devices have become more intelligent. For example, after a hole is drilled in the door, the wire is inserted from the outside of the door and the end of the inserted wire is pressed to press the operation button installed in the indoor housing of the door. In particular, the more the hole is formed near the interior housing of the door, the more easily the operation button can be pressed using the wire.

As such, recently, hacking attempts to disable the digital door lock device by using the own operation of the digital door lock device without damaging the digital door lock device have emerged. Therefore, there is a need to effectively block such hacking attempts.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a digital door lock device having improved security by effectively blocking hacking attempts made by pressing an operation button of the door lock device after forming a hole in the door. To provide.

In order to achieve the above object, the digital door lock device according to the present invention includes a locking key coupled to the door to lock and unlock the door; A drive source for driving the clamp and driven by a power source; A user interface for receiving an authentication command from a user and outputting a driving signal for driving the driving source to operate the catch; An indoor housing coupled to an indoor side of the door; A substrate coupled to an indoor side or an outdoor side of the door; A circuit formed on the substrate and to which power is applied; And a controller for controlling the operation of the driving source based on a driving signal output from the user interface and detecting a change in electrical characteristics of the circuit generated when the circuit is physically damaged.

According to the present invention, it is possible to effectively block the hacking attempt made by pressing the operation button of the door lock device after forming a hole in the door, thereby improving the security of the door lock device.

In addition, the door can be beautifully decorated through the patterns and patterns formed on the base and the lights installed on the base, so that the user can feel aesthetics.

1 is a schematic side view of a digital door lock device according to an embodiment of the present invention, FIG. 2 is a schematic front view of the digital door lock device shown in FIG. 1 as viewed from an indoor side, and FIG. 3 is a substrate shown in FIG. Is the rear view of.

1 to 3, the digital door lock device according to the present embodiment includes a mortis, an outdoor housing 20, a user interface 30, an indoor housing 40, a substrate 50, and a base ( 60 and a control unit (not shown).

The mortis is a case 11 inserted into the side of the door 1 so as not to protrude and immerse, and a clamp 12 and a latch bolt installed in the case so as to be linearly movable in a direction protruding and immersed with respect to the case 11. 13 and a drive source (not shown) for driving the linear movement of the clamp 12.

The clamp 11 and the latch bolt 13 is inserted into and detached from the clamp receiving hole 3 or the latch bolt receiving hole (4) formed in the door holder (2). Then, the door 1 is locked when the clamp 12 is inserted into the clamp receiving hole 3, and on the contrary, the door 1 is unlocked when the clamp 12 is released from the clamp receiving hole 3. The latch bolt 13 is for preventing the door 1 from being arbitrarily opened due to wind or weak vibration, and is elastically biased in the direction to be inserted into the latch bolt receiving hole 4. And in conjunction with the rotation of the interior handle 41 is moved away from the latch bolt receiving hole (4).

Moreover, the drive source is for linearly driving the clamp 12, and is comprised by the motor, solenoid, etc. which operate by a power supply. When the motor rotates or the solenoid is in a linear motion, the clamp 12 is in linear motion in conjunction with the operation of the motor or solenoid.

The outdoor housing 20 is coupled to the outdoor side of the door 1. The outdoor handle 21 is rotatably coupled to the outdoor housing 20. The outdoor handle 21 is provided with a key hole (not shown) into which a key is inserted.

The user interface 30 is installed in the outdoor housing 20. The user interface authenticates a user and outputs a driving signal to the controller when authentication is performed. The user interface may be configured in various ways such as a keypad having a plurality of buttons or a fingerprint reader for recognizing a fingerprint. In particular, the user interface may include a keypad. Therefore, when the user's authentication command is input to the keypad through a method of inputting a preset password, the user authentication is made and the driving source is driven to operate the lock 12.

The interior housing 40 is coupled to the interior side of the door 1, and the interior handle 41 is rotatably coupled to the interior housing 40. The indoor housing 40 houses a battery for supplying power. The battery supplies power to the driving source, the user interface 30 and the controller. The indoor housing 40 is provided with an operation button 42 for operating a drive source and a knob 43 for manually driving the clamp 12.

The substrate 50 is coupled to the interior side of the door 1. The substrate 50 is formed in a plate shape, and a circuit 51 to which power is applied is formed on the rear surface of the substrate 50, that is, the surface facing the indoor side of the door 1. Here, the circuit 51 may be configured in various forms as long as the electrical characteristics of the circuit change in response to physical damage to a portion of the circuit. In particular, in the present embodiment, the circuit 51 is evenly formed in a zigzag form on the entire back surface of the substrate 50. It consists of a conducting line through which current flows. In addition, a pair of terminals 511 and 512 are provided on one side and the other side of the conductive line 51 to receive power from a battery, respectively. The conducting wire 51 is more preferably formed densely in the entire back surface of the substrate 50. This is because, as the intruder penetrates the door 1 and the substrate 50 to make a hole, the denser the conductive line 51 is formed, the higher the probability that the conductive line will be damaged. In addition, a protective film (not shown) may be attached to the substrate 50 to protect the circuit.

On the other hand, when the circuit 51 is comprised by an energized line, the electrical characteristic change of a circuit says disconnection. That is, when a part of the electricity supply wire 51 is damaged by the hole 5 which penetrates through the door 1 as shown by the dotted line in FIG. 3, a disconnection will arise in the electricity supply wire 51. FIG. .

In addition, the size of the substrate 50 may be variously set according to a user's selection. In particular, as the size of the substrate 50 increases, it becomes more difficult to form a hole in the door 1 that is accessible near the interior housing 40, and thus the operation button provided in the interior housing 40 42) It is also difficult to press using a wire or the like. Therefore, as long as the substrate 50 is formed to have the same size as that of the door 1, the hacking attempt as described in the related art can be blocked at the source.

The base 60 is formed to have the same size as or larger than the size of the substrate 50. Base 60 is also made of a plate shape, it is coupled to the substrate 50. The substrate 50 is disposed between the base 60 and the door 1 so that the substrate 50 is not visible from the outside. In addition, the indoor housing 40 is directly coupled to the base 60.

The base 60 is formed so that a pattern or pattern 61 such as a flower, a mountain or a tree pattern is visible from the outside. Here, the pattern or pattern is formed by printing on the surface of the base 60, or by attaching a thin sheet on which the pattern or pattern is printed on the base.

In addition, a pair of indicators 62 for emitting light are coupled to the base 60. Each indicator 62 is preferably composed of a light emitting diode (LED) with low power consumption. In addition, each indicator 62 is preferably in harmony with the pattern or pattern 61 formed on the base 60 to create an aesthetic sense. For example, when the pattern or pattern 61 of the base is formed of a tree as shown in FIG. 2, the light 62 is configured to emit red light so that it can be represented by the sun. You can feel the nature. And, the pattern or pattern may be configured in various ways different from that shown in FIG. In addition, the substrate 50 is provided with a pair of power supply lines 52 and 53 for supplying power to each of the indicators 62.

The controller (not shown) performs an operation of controlling the driving source. That is, when a drive signal output from the user interface 30 is output to the controller, when a drive signal corresponding to user authentication is output, the drive is operated to unlock the door, and the drive signal corresponding to the user's authentication failure. If is outputted, the driving source is not operated to keep the locked state of the door 1 continuously. And, if the user authentication fails, if the number of authentication failures is excessive, such as sending out a signal to the security company by wire or wireless as needed or alarm signal to the alarm device (not shown) built in the door lock device 100 Output

In addition, the controller is electrically connected to the terminals 511 and 512 of the circuit, respectively, to perform an operation of preventing the hacking of the door 1. That is, when the intruder damages the circuit 51 by drilling a hole in the door 1, a disconnection occurs and no current flows in the circuit 51, so that the controller detects the disconnection. Output the dispatch signal to the security company by wire or wireless or output the alarm signal to the alarm device (not shown) built in the door lock device.

On the other hand, the terminals 511 and 512 of the circuit are directly connected to the control unit by the terminal contact connection method or the connector connection method together with the terminals of the power supply lines 52 and 53 for supplying power to the indicator 62.

In the digital door lock device 100 configured as described above, the substrate 50 and the base 60 on which the circuit 51 is formed on the indoor side of the door 1 are coupled, and the indoor housing 40 on the base 60. ) Is coupled to each other, and as described in the prior art, when the intruder makes a hole in the vicinity of the indoor housing 40, the circuit 51 of the substrate is damaged and a disconnection is generated. Such disconnection is detected by the control unit, and accordingly, the security company is dispatched or an alarm sounds. Therefore, it is possible to effectively prevent the intruder attempt to intrude without breaking the digital door lock device.

In particular, when the substrate 50 is formed in the same size as the interior side of the door and coupled to the interior side of the door 1, intrusion of the intruder may be fundamentally blocked.

In addition, a pattern or a pattern 61 is formed on the base 60, and an indicator 62 is installed to harmonize with the pattern or the pattern of the base, so that when the user looks at the door, the user feels the picture as if it were a picture. You will feel the aesthetics you can get. Thus, the door 1 is more luxuriously decorated.

On the other hand, in the present embodiment, the circuit formed on the substrate is simply composed of a conductive line, but as shown in FIG. 4, a plurality of resistors may be arranged in parallel.

In other words, the circuit 51a of the present embodiment includes the conducting wire 54 and a plurality of resistors 55 arranged in parallel. Thus, when the circuit 51a is comprised and an intruder drills the hole 5 in a door and damages the electricity supply line 54 of a circuit, as shown by the dotted line in FIG. 4, power is supplied to the circuit 51a. The resistance value between the terminals 511 and 512 is changed. Such a change in resistance value is detected by the control unit, and eventually a security company is dispatched or an alarm sounds. In addition, even if the resistance is damaged when the hole 5 is drilled in the door, the resistance value of the circuit 51a is changed as described above.

On the other hand, if the circuit is configured differently from the previous embodiment, the change in the electrical characteristics of the circuit, in addition to the change in the disconnection or the resistance value described in the previous embodiment, such as a change in the voltage applied to the circuit, a change in the current flowing through the circuit or a short Can be set.

And, in the above embodiment, the indoor housing is configured to be coupled to the base, but as shown in FIG. 5, the indoor housing 40 is directly coupled to the indoor side of the door 1, and the base 60 is indoor. It may be configured to be arranged around the side housing 40, in particular above the indoor housing 40. At this time, the substrate (not shown) is also formed in the same size as the base 60 is disposed between the base 60 and the interior side of the door (1).

As mentioned above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the technical idea of the present invention. It is obvious.

For example, in the present embodiment, the clasp is configured to be linearly movable, but the clasp may be configured to rotate. And, as is widely known, the door may be locked and unlocked by applying a magnetic field around the clamp or not applying the magnetic field in a state where the clamp is fixed to the door so as not to move.

In addition, in the present embodiment, the handle is provided in the outdoor housing and the indoor housing, respectively, but it is not necessarily configured to be provided with the handle. In general, a door lock device with a handle is called a primary key, but a door lock device without a handle is called an auxiliary key. The door lock device, which is called an auxiliary key, does not have a handle, a case, and a latch bolt, unlike the embodiment described above, and a fastener is installed in the indoor housing. Then, the clamp receiving hole is inserted into and separated from the clamp is formed in a separate part that is coupled to the door jamb. In addition, a motor for driving the clamp is also installed in the indoor housing.

In addition, in the present embodiment, the substrate and the base are configured to be coupled to the indoor side of the door, but the substrate and the base may be configured to be coupled to the outdoor side of the door.

In addition, although the outdoor housing is installed in the outdoor side of the door and the user interface is installed in the outdoor housing in the present embodiment, the digital door lock device may be configured not to include the outdoor housing. As described above, in the digital door lock device having no outdoor housing, the user interface is embedded in the indoor housing and the antenna which receives the authentication signal output from the remote controller of the user and the signal received by the antenna are processed and transmitted to the controller. It can be configured as a module. Therefore, in the door lock device having no outdoor housing, the drive source can be operated wirelessly only by using the remote control in the outdoor side of the door, and no component of the digital door lock device is exposed on the outdoor side of the door. On the other hand, even if the digital door lock device has an outdoor housing, as described above, the user interface may be configured as an antenna and an antenna module and embedded in the indoor housing.
