Description

Door lock device

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

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

The digital door lock device is classified into a main key door lock device having a handle and a door lock device having a sub key without a handle. The door lock device (not shown) in the form of an auxiliary key is widely known as a housing coupled to the interior side of the door, a clasp moving linearly in a direction protruding and immersing with respect to the housing, and a rotational force of the motor as a linear driving force of the clasp. It includes a power transmission means for transmitting, a keypad coupled to the outdoor side of the door and receiving a password for operating the motor, and a knob rotatably coupled to the housing and interlocked with the rotation about the housing to drive the clamp. . The power transmission means includes a reduction gear for reducing the rotational force of the motor and a rack pinion structure for converting the rotational force of the motor decelerated by the reduction gear into a linear driving force.

By the way, in the auxiliary lock-type door lock device configured as described above, the knob is configured to be connected to the motor via the power transmission means, so that the motor or knob also always rotates when the knob or the motor is rotated. For example, if the knob is rotated to unlock the door, the motor will also rotate by the angle necessary to unlock the door. As described above, the motor and the knob are configured to rotate together with each other, and thus, the motor and the knob must rotate up to the knob when the motor is rotated, thereby overloading the motor and ultimately deteriorating the life of the motor. In addition, since the knob must be driven with a power transmission means such as a reduction gear when the knob rotates, it causes a lot of force.

In addition, when the clamp is forcibly retracted by inserting a separate tool through a gap between the door and the door holder while the door is locked, there is a limit that the clamp is retracted and the door is unlocked even though there is no user authentication.

On the other hand, in recent years, a panic function that can be easily escaped from the room in a mentally panic state in an emergency to minimize human injury. That is, when a fire or an earthquake occurs on the indoor side of the door, the person on the indoor side becomes mentally panicked and rotates only the simplest operation, that is, the indoor handle or knob. It was necessary to unlock the door just by turning the knob. A door lock device capable of achieving such a panic function is already commercially available and has been disclosed in a number of patent documents such as Korean Patent No. 799,932.

However, in the door lock device that performs the above-described panic function, the indoor user can unlock the door by rotating only the indoor handle or the knob, so that a child or a patient suffering from mental illness such as dementia can easily escape. There was a need to disable the panic function.

In addition, the intruder who intruded into the window, etc. can also easily escape through the door simply by rotating the interior handle, there was a problem that there is a limit to security.

The present invention has been made to solve the above problems, the object of the present invention is that the overload is not applied to the motor or solenoid can increase the life of the motor or solenoid, so that less power is required to rotate the knob In addition, it is possible to selectively implement a panic function, which can minimize human injury in an emergency and effectively prevent an intruder from escaping through the door, thereby providing a door lock device having greatly improved security.

In order to achieve the above object, the door lock device according to the present invention comprises a housing coupled to the door; A lock for locking and unlocking the door, the lock being coupled to the housing to be movable in a direction protruding and immersing with respect to the housing; Coupled to the housing so as to be rotatable with respect to the housing, pressurizing the catch so that the catch moves in a direction protruding with respect to the housing, interlocked with rotation in one direction, interlocked with rotation in an opposite direction of the one direction; A pressing member which presses the catch so that the catch moves in a direction immersed with respect to the housing, and which is linearly movable between a reference position and a spaced position spaced apart from the reference position in the direction of the center of rotation with respect to the housing; The pressing member is coupled to the pressing member so as to be relatively rotatable within the relative rotation angle range with respect to the pressing member, and when the rotation is within the relative rotation angle range, the pressing member moves linearly from the reference position to the separation position. A first driving member for urging the member and urging the urging member to rotate together with the urging member when rotating at an angle outside the relative rotation angle range; Is coupled to the housing so as to be rotatable or linear movement with respect to the housing, to press the pressing member disposed in the reference position during rotation or linear movement with respect to the housing and to rotate or linear movement with respect to the pressing member disposed in the spaced position A second driving member connected to the pressing member and rotatable or linearly moving relative to the first driving member; And a locking position to which the catch is locked so as to move the catch lock which locks the door in a direction immersed with respect to the housing to prevent the door from being unlocked and to move the catch to prevent a catch with the catch when the catch is moved. It is coupled to the housing so as to be movable between the anti-locking positions spaced apart from the path, and is elastically biased toward the locking position, and interlocked with the rotation of the first drive member or the rotation or linear movement of the second drive member And a locking member pressurized by the first driving member or the second driving member to move from the position to the locking prevention position.

In addition, another type of door lock device according to the present invention comprises a housing coupled to the door; A lock for locking and unlocking the door, the lock being coupled to the housing to be movable in a direction protruding and immersing with respect to the housing; Coupled to the housing so as to be rotatable with respect to the housing, pressurizing the catch so that the catch moves in a direction protruding with respect to the housing, interlocked with rotation in one direction, interlocked with rotation in an opposite direction of the one direction; A pressing member for urging the catch so that the catch moves in a direction immersed with respect to the housing; A first driving member coupled to the housing so as to be rotatable with respect to the housing, the first driving member being coupled to the rotation about the housing and connected to the pressing member so that the pressing member rotates in the one direction or the other direction; Coupled to the housing so as to be rotatable or linearly movable relative to the housing, pressurizing the urging member so that the urging member rotates in the one or the other direction when rotating or linearly moving with respect to the housing, and with respect to the first driving member.

FIG. 6 is a schematic perspective view of the pressing member, the first driving member, and the second driving member, and FIG. 6 is a schematic view for explaining a coupling relationship between the pressing member and the first driving member shown in FIG. 3.

1 to 6, the door lock device according to the present embodiment includes an outdoor side unit (not shown) and an indoor side unit 100.

The outdoor side unit (not shown) includes an outdoor side housing coupled to the outdoor side of the door 2 as well known, and a user authentication unit coupled to the outdoor side housing to authenticate the user. The user authentication unit includes a keypad for entering a number, a biometric device for recognizing a fingerprint or eyeball, and the like, and when a preset password is input to the keypad or a fingerprint or eyeball registered in advance is recognized by the biometric device. User authentication is successfully performed and the motor described below is operated.

The indoor unit 100 is coupled to the indoor side of the door 2, the indoor housing 10, the clamp 20, the pressing member 30, the first driving member 40, The second driving member 50, the locking member 60, and the moving member 70 are included.

The interior housing 10 is coupled to the interior side of the door 2 and includes a case 11 and a cover 12 that are coupled to each other. The case 11 is formed in a rectangular box shape as a whole, and the cover 12 is formed in a plate shape to close the case internal space. The case 11 is formed with a fastener insertion hole 111 into which the fastener 20 is inserted. In addition, the cap member 3 is coupled to the door post 1 so as to face the indoor housing 10. The cap member 3 is formed with a locking key insertion hole (4).

The catch 20 is for locking and unlocking the door 2. The catch 20 is installed to be linearly movable in the horizontal direction in a direction projecting and immersed with respect to the housing 10. When the clamp 20 is inserted into the clamp insertion hole 4 formed in the cap member 3 as shown in FIG. 1, the door 2 is locked, and the clamp 20 is shown in FIG. The door 2 is unlocked when it is disengaged from the clamping hole 4 of the cap member. The clasp 20 is formed with a long hole 21 along the linear movement direction of the clasp 20 long. A bolt 211 is inserted into the long hole 21, and the bolt 211 is screwed to the case 11. Therefore, the linear movement of the clamp 20 is guided by the bolt 211 inserted into the long hole 21. In addition, the clamping groove 20 is formed with a pressing groove 22 to be opened downward. Then, the locking jaw (20) is formed with a locking jaw (23).

The pressing member 30 is rotatably coupled to the indoor side housing 10. The pressing member 30 is formed to protrude in the rotational radius direction of the pressing member 30 on the main body 31 and the outer circumferential surface of the main body 31, respectively, and the cross section with respect to a plane perpendicular to one direction has a rectangular shape. It includes a pressing portion (32). The end portion of the pressing portion 32 is inserted into the pressing groove portion 22 of the clamp. When the pressing member 30 is rotated about the center of the body portion 31, it is interlocked with it, the locking clamp 20 is linearly moved in a direction protruding or immersed with respect to the indoor housing (10). That is, in the state in which the bar 2 shown in FIG. 1 is locked, when the pressing member 30 rotates clockwise, the pressing portion 32 of the pressing member is one inner side surface of the pressing groove portion 22. The door 2 is unlocked as shown in FIG. On the contrary, when the pressing member 30 rotates in the counterclockwise direction in the state shown in FIG. 14, the pressing part 32 of the pressing member presses the other inner side surface of the pressurized groove part 22 to protrude the clamp. As a result, the door 2 is locked.

In addition, the pressing member 30 is linearly movable between the reference position shown in FIG. 5 and the separation position shown in FIG. 12. Of course, to be precise, FIG. 12 illustrates a state in which the pressing member is rotated at an angle in a spaced position. Here, the linear movement direction between the reference position and the spaced apart position of the pressing member 30 is parallel to the direction of rotational axis of the pressing member 30 and also parallel to the thickness direction of the door 2. As such, when the pressing member 30 is linearly moved between the reference position and the separation position, the pressing member 30 is disposed at different heights from the bottom surface of the case 11. The pressing member 30 is elastically biased toward the reference position by the compression coil spring 34. One end of the compression coil spring 34 is in contact with the plate portion 43 of the first drive member, the other end of the compression coil spring 34 is in contact with the main body 31 of the pressing member. In addition, the plate-shaped portion 43 and the main body portion 31 is formed with a groove in which the compression coil spring is seated so as to prevent the compression coil spring 34 from being separated. Then, the linear movement of the pressing member 30 is made in conjunction with the rotation of the first drive member (40). For reference, in FIGS. 5 and 12, the compression coil spring 34 is omitted for the sake of simplicity, and the grooves formed in the plate portion 43 and the main body portion 31 are also omitted. 9, only the pressing member 30, the first driving member 40, and the second driving member 50 are illustrated in FIG. 9. 4, only the pressing member 30 is shown.

On the other hand, the body portion 31 of the pressing member is formed with a through hole 311 and a pair of insertion grooves 312 respectively disposed at both sides of the through hole 311. The through hole 311 is formed through the main body 31, and the first driving member 40 is rotatably inserted into the through hole 311. The inner surface of each of the insertion grooves 312 includes a horizontal portion 313 and a pair of inclined portions 314 disposed on both sides of the horizontal portion 313 and connected to the horizontal portion 313. The horizontal portion 313 has a normal vector orthogonal to the thickness direction of the door 2. The pair of inclined portions 314 are disposed to be spaced apart from each other by a predetermined distance, and are each formed in a plane inclined with respect to the linear movement direction of the pressing member 30 to form a plane symmetry. In the present embodiment, the inclined portion 314 is formed in a planar shape, but is not necessarily limited thereto, such as a convex curved shape is pressed by the first driving member 40 to the pressing member 30 to the spaced position. Any shape may be used as long as it is configured to move linearly. In addition, a pair of pressurized portions 315 are disposed on inner surfaces of the respective insertion grooves 312. The pair of pressurized portions 315 are respectively connected to a pair of inclined portions 314, the pair of pressurized portions 315 face each other, and the normal vector of each of the pressurized portions 315 is a horizontal portion. Orthogonal to the normal vector of (313).

The first driving member 40 is rotatably coupled to the indoor housing 10. The first drive member 40 includes a cylinder portion 41 and a pair of pressing portions 42.

The cylinder portion 41 is rotatably inserted into the through hole 311 formed in the body portion 31 of the pressing member. The cylinder portion 41 becomes the rotation center of the first driving member 40. The first driving member 40 is disposed coaxially with the pressing member 30. And the cylinder part 41 is rotatably inserted in the indoor side housing 10, The cylinder part 41 is being fixed so that it may not move in the thickness direction of the housing 10, ie, the thickness direction of the door 2. In FIG. .

The pair of pressing portions 42 are formed to protrude from the outer circumferential surface of the cylinder portion 41, respectively. The protruding directions of the pair of pressing portions 42 face in opposite directions to each other, and the pair of pressing portions 42 form 180 °. A pair of pressing portions 42 are inserted into the insertion groove portion 312 of the pressing member, respectively, as shown in FIG. Each pressing portion 42 is disposed between the pair of inclined portions 314 in the insertion groove portion 312. For reference, FIG. 6 is a front view of the door 2, that is, the rear surface of the first driving member shown in FIG. 1, and the interlocking operation of the pressing member 30 and the first driving member 40. All other components are omitted to explain the structure.

The first driving member 40 rotates relative to the pressing member 30 within a preset relative rotation angle range. That is, in the state shown in FIG. 6, when the first driving member 40 rotates in the counterclockwise direction, as shown in FIG. 8, the pressure of the pressing member 42 of the first driving member is reduced. The first driving member 40 rotates relative to the pressing member 30 until the moment of contact with the pressing unit 315. As such, while the first driving member 40 relatively rotates, since the pressing portion 42 of the first driving member presses the inclined portion 314 of the pressing member, the pressing member 30 is shown in FIG. 5. Ascend in the closed state and are placed in the spaced position. When the first driving member 40 continues to rotate counterclockwise even after the pressing part 42 of the first driving member is in contact with the pressing part 315 of the pressing member, the first driving member is pressed. Since the part 42 presses the pressurized part 315 of the pressing member, the pressing member 30 rotates to the position shown in FIG. 11 while being disposed at a spaced position. At this time, the state of the pressing member 30 is also shown in FIG.

Meanwhile, even when the first driving member 40 rotates clockwise in the state shown in FIG. 15 (the pressing member 30 is disposed at a reference position by the elastic force of the compression coil spring 34), the same as described above. The first driving member 40 and the pressing member 30 is to operate. That is, the first driving member 40 moves relative to the pressing member 30 and moves the pressing member 30 until the pressing portion 42 of the first driving member contacts the pressed portion 315 of the pressing member. The position of the first driving member 40 is rotated clockwise even after the pressing portion 42 of the first driving member contacts the to-be-pressed portion 315 of the pressing member. 40 and the pressing member 30 is rotated together. As described above, the first driving member 40 has a predetermined relative rotation angle range, that is, the pressing portion 42 of the first driving member rotates clockwise or counterclockwise within the insertion groove 312 to be pressurized. Relatively rotates with respect to the pressing member 30 within the angle range before contacting with), and rotates with the pressing member 30 when it exceeds the relative rotating angle range.

Then, after the first driving member 40 rotates out of the relative rotation angle range and rotates together with the pressing member 30, the pressurized portion 315 of the pressing member by the pressing portion 42 of the first driving member. When the pressure is released, the pressing member 30 tries to move linearly toward the reference position by the elastic force of the compression coil spring 34. At this time, the protrusion 33 of the first driving member moves to the second driving member 50. In the positional relationship that can be inserted into the groove portion 55 of the), the pressing member 30 is moved to the reference position. In this process, the pressing portion 42 of the first driving member rotates in a direction opposite to the direction in which the pressing portion 42 is rotated together with the pressing member 30 while being in contact with the inclined portion 314 of the pressing member. ) Is placed between. On the other hand, when the projection 33 of the first driving member is in a positional relationship that cannot be inserted into the groove portion 55 of the second driving member 50 as shown in FIG. 12, the first driving member 40 Subsequently, it is disposed at a spaced position, and by rotating the second driving member 50 through a separate operation it is possible to move the first driving member to the reference position.

Meanwhile, the first driving member 40 is connected to the knob 80. The knob 80 is rotatably coupled to the indoor housing 10. The knob is inserted into the cylinder portion of the first driving member to be one body with the first driving member and includes a main body (not shown) formed long in the thickness direction of the door, thereby rotating together with the first driving member. Knob 80 is provided with a handle 81 for the user to hold and turn to drive the clamp 20. The handle portion 81 protrudes from the knob body portion 82 and is formed in a substantially rectangular shape. The handle portion 81 is set so that its longitudinal direction is rotated by an angle to the right with respect to the vertical direction while the door 2 is locked. In particular, in the present embodiment, the first drive member 40 and the knob 80 is formed in one body. When the knob 80 is rotated, the first driving member 40 is rotated, and thus the pressing member 30 can be rotated along with the linear movement.

The second driving member 50 is rotatably coupled to the interior of the indoor housing 10. The second driving member 50 is fitted to the cylinder portion 41 of the first driving member, and the second driving member 50 is disposed coaxially with the first driving member 40. The second driving member 50 is arranged to have an annular shape around the cylinder portion 41 of the first driving member, and includes a gear portion 51 composed of a plurality of teeth, a first pressing protrusion 52 and a second. The pressure protrusion 53 is formed. The gear unit 51 directly engages with the gear member 86 coupled to the output shaft of the motor 85, so that the second driving member 50 rotates when the motor 85 is operated. Here, the motor 85 operates when the user is authenticated by the user authentication unit, and the shape display of the gear unit 51 is omitted in FIGS. 5 and 12 to simplify the drawing. The first pressurizing protrusions 52 and the second pressurizing protrusions 53 are formed in a substantially semi-circular shape with their respective ends facing each other. Since the first pressing protrusion 52 and the second pressing protrusion 53 are disposed on the rotation path of the pressing part 32 of the pressing member when the pressing member 30 is disposed at the reference position, the second driving member ( When the 50 is rotated, the first pressing protrusion 52 or the second pressing protrusion 53 presses the pressing part 32 of the pressing member to rotate clockwise or counterclockwise. On the other hand, when the pressing member 30 is disposed in the spaced apart position, the first pressing projection 52 and the second pressing projection 53 is a rotation path of the pressing portion 32 of the pressing member as shown in FIG. Since the second drive member 50 is rotated relative to the pressing member 30 when the second drive member 50 is rotated.

When the second driving member 50 is rotated while the pressing member 30 is disposed at the reference position, the first pressing protrusion 52 or the second pressing protrusion 53 of the second driving member presses the pressing member. Pressing the portion 32 to rotate the pressing member (30). For example, when the door is locked, as shown in FIG. 1 or 17, when the second driving member 50 is rotated in the clockwise direction, the first pressing protrusion 52 may move the pressing part 32. The pressing member 30 is rotated in a clockwise direction by pressing, and the pressing part 32 presses the inner surface of the pressurized groove part 22 in the rotation process, so that the clamp 20 is immersed with respect to the housing 10. The door 2 is released. At this time, that is, when the pressing member 30 is pressed by the second driving member 50 and rotates, the pressing portion 42 of the first driving member is pressed in contact with the inclined portion 314 of the pressing member. In addition, the first driving member 40 also rotates together, and eventually, the knob 80 forming the body with the first driving member 40 also rotates. In addition, while the pressing member 42 of the first driving member is pressed by the inclined portion 314 of the pressing member when the pressing member 30 rotates, the pressing member 30 is pressed by the elastic force of the compression coil spring 34. Since the elastic bias toward the reference position, the pressing member 30 does not move to the spaced apart position when the second driving member 50 rotates. That is, the elastic force of the compression coil spring 34 prevents the movement of the pressing member 30.

In addition, the third driving protrusion 54 is also formed on the second driving member 50. The third pressurizing protrusion 54 protrudes in a direction opposite to the first pressurizing protrusion 52. The third pressurizing protrusion 54 has an arc shape.

The locking member 60 is rotatably coupled to the indoor side housing 10. The rotation center of the locking member 60 is a pivot pin 63 coupled to the locking member 60 and the indoor housing 10. The locking member 60 is divided into a locking part 61 and a pressurized part 62 with respect to the pivot pin 63. The locking member 60 is rotatable between the locking position and the unlocking position.

When the locking member 60 is disposed at the locking position shown in FIG. 1, the locking portion 61 is inserted into the locking jaw 23 of the clamp when the door 2 is locked, thereby locking the door 2. The retraction of the catch 20 is prevented and the locked state of the door is maintained continuously. In particular, as shown in FIG. 3, even when the direction in which the locking jaw 23 pushes the locking portion 61 does not pass through the rotation center of the locking member 60, when the locking clamp 20 is retracted, the locking member Even if it retreats slightly in the state shown in FIG. 3, since the to-be-pressed part 62 of the catching member will be caught by the 3rd pressurizing protrusion 54 of the 2nd drive member, rotation of the catching member 60 counterclockwise will be performed. This prevents the locking state of the door 2 from being maintained. At this time, the pressurized part 62 presses the third pressurizing protrusion 54, but the friction force between the gear part 51 and the gear member 86 of the second driving member is appropriately set so that the second driving member ( The rotation of 50) is also prevented. Therefore, the hacking tool is inserted through the gap between the door 2 and the door holder 1 so that the clamp 20 cannot be forcibly retracted. In addition, the first driving member 40 is rotated in the state shown in FIG. 7 and the pressing member 30 is disposed at a spaced apart position, and then further rotated in the same direction to move the clamp 20 over the position shown in FIG. 10. Even if it tries to rotate to a position that can be retracted, the catching portion 61 is caught by the catching jaw 23 and the pressurized portion 62 of the catching member is caught by the third pressing projection 54 of the second driving member. Thus, the locked state of the door 2 continues to be maintained.

And, when the locking member 60 is disposed in the locking position shown in Fig. 15 or 17, the locking portion 61 of the locking member is completely separated from the movement path of the clamp 20. In addition, the pressing portion 62 of the locking member is also separated from the rotation path of the third pressing projection 54 of the second driving member. Therefore, even when the first driving member 40 is rotated, the door can be unlocked.

The locking member 60 is elastically biased toward the locking position. Here, applying the elastic force to the locking member is a torsion spring (not shown), one side of the torsion spring is fixed to the indoor housing 10 and the other side of the torsion spring is fixed to the locking portion 61 of the locking member.

Then, in conjunction with the rotation of the second drive member 50 of the locking member 60 moves from the locking position to the locking position. That is, when the second driving member 50 is rotated in the clockwise direction in the state shown in FIG. 1 (in the state shown in FIG. 3, the second driving member 50 is rotated in the counterclockwise direction). The third pressing projection 54 of the second driving member is in primary contact with the pressurized portion 62 of the locking member and then pressurizes the wave pressing portion 62 of the locking member, the locking member 60 1 rotates counterclockwise in the state shown in FIG. 1, so that the locking portion 61 is separated from the locking jaw 23, as shown in FIG. 13, and the pressurized portion 62 includes the third pressing protrusion ( Deviation from the rotation path of 54). Thereafter, when the second driving member 50 is further rotated in the clockwise direction, the locking portion 61 of the locking member presses the pressurized groove portion 22 of the clamp, so that the door 2 is shown in FIG. It is unlocked as shown.

The moving member 70 is for fixing the position of the locking member 60 to the locking prevention position. The moving member 70 is exposed to the indoor housing 10, the holding element 71 that the user can hold and drive linearly, the plate-like element 72 to which the holding element 71 is fixed, the plate-like element 72 It includes a pressing element (73) fixed to and disposed inside the case (11).

The moving member 70 is linearly movable between the pressure release position and the pressure position. When the movable member 70 is disposed at the pressure release position shown in FIGS. 1 and 2, the pressing element 73 of the movable member does not press the locking member 60, and thus the locking member 60 is torsioned. It is arranged in the locking position by the elastic force of the spring. On the other hand, when the movable member 70 is linearly moved to the left side from the pressure release position and disposed in the pressing position shown in FIG. 17, the pressing element 73 of the movable member is caught by the locking member 60 in the process of moving the movable member 70. Press) to rotate the locking member 60 counterclockwise. Therefore, the locking portion 61 of the locking member is separated from the locking jaw 23 of the clamp as shown in FIG. Then, the moving member 70 overcomes the elastic force of the torsion spring in the pressing position and maintains its position. In particular, in the present embodiment, the moving member 70 is caught by the locking jaw 611 formed on the locking portion 61 of the locking member, and its position is maintained.

In addition, the door lock device 100 of the present embodiment, the button unit 90, the user authentication unit 91, the position detection sensor 92, the door opening and closing detection sensor 93, the door locking detection sensor 94 And a control unit 95.

The button unit 90 is coupled to the indoor housing 10 and exposed to the indoor side of the door 2. The button unit 90 outputs an operation signal for operating the motor 85. Here, the button unit 90 is composed of a dome switch.

The user authentication unit 91 is coupled to the outdoor side housing (not shown). The user authentication unit 91 is for authenticating the user so that only the authenticated user can open and close the door lock device. The user authentication unit 91 may include a keypad for inputting a preset password or a biometric unit for scanning biometric information such as eyeballs or fingerprints. When user authentication is made, an operation signal for operating the motor 85 is output.

The position detection sensor 92 detects the position of the moving member 70. The position sensor 92 may be configured in various forms such as a push switch or a photo sensor including a light emitting element and a light receiving element. The position detecting sensor 92 outputs a signal corresponding to the moving member 70 when the moving member 70 is disposed at the pressing position, and does not output a signal when the moving member 70 is disposed at the pressing release position. For example, when the position detecting sensor 92 is configured as a push switch, when the push switch is disposed in the movement path of the moving member 70 and the moving member is placed in the press position, the push switch is pressed to output a signal. When the moving member 70 is separated from the pressing position, the pressing of the push switch is released and no signal is output. In addition, the projection 721 is formed on the plate-like element 72 of the moving member, and the position detecting sensor 92 may be implemented by disposing the light emitting element and the light receiving element with the protrusion 721 interposed therebetween.

The door open / close detection sensor 93 outputs a signal corresponding to the opening and closing of the door 2, respectively. The door opening / closing detection sensor 93 indirectly detects the opening and closing of the door by detecting the position of the exiting member 13 which is coupled to the indoor housing 10 so as to be projected. The projecting member 13 is elastically biased in a direction protruding with respect to the indoor housing 10 by a compression coil spring (not shown) installed inside the indoor housing 10. When the projecting member 13 protrudes, the opening of the door 2 is detected, and when the projecting member 13 is pressed by the cap member 3, the closing of the door 2 is sensed. The sunken member 13 is formed to be inclined to the side so that the door (1) is closed by the edge of the cap member 3 can be moved in the immersion direction. The door opening and closing detection sensor 93 may be configured in various forms, such as a push switch or a photo sensor, similarly to the position detection sensor 92.

It is fixed to the door of the combined appearance member and detects a magnet (not shown) fixed to the door holder when the door is closed and outputs a signal. However, the door open / close detection sensor 93 does not detect a magnet when the door is opened and does not output a signal.

The door locking detection sensor 94 detects the position of the clamp 20 and outputs signals corresponding to the locking and unlocking of the door, respectively. The door locking detection signal detects the position of the clamp 20 and outputs a signal. Like the position detection sensor 92, the door locking detection signal may be configured in various forms such as a push switch or a photo sensor.

The controller 95 receives a signal output from the position sensor 92, the door open / close detection sensor 93, and the door locking detection sensor 94 to control the operation of the motor 85.

First, when a signal corresponding to that the moving member 70 is disposed in the pressing position is input, the locking between the locking portion 61 of the locking member and the locking jaw 23 of the clamp is released as shown in FIG. When the operation signal for operating the motor 85 is input by pressing the button unit 90 on the indoor side of the door 2 or the user authentication is performed on the outdoor side of the door, the door is unlocked by operating the motor. As such, when the state in which the movable member 70 is disposed at the pressing position is referred to as the first mode, the user can set the first mode by driving the movable member 70, and in the first mode, the clamping mechanism of the knob 80 is set. In addition to driving (20), the clasp driving through the button unit 90 or the user authentication unit 91 can be performed.

Then, when a signal corresponding to the moving member 70 is disposed at the pressure release position, a signal corresponding to the closing of the door and a signal corresponding to the locking of the door are input, As shown in Figure 1 it is caught by the locking jaw 23 of the clamp. In this state, even if the button unit 90 is pressed or the user authentication 91 is made, the control unit 95 does not operate the motor 85, so that the lock 20 is stopped. Thus, the locked state of the door 2 is maintained continuously. As such, when the movable member 70 is disposed at the pressure release position and the locked door is closed, the user operates the movable member 70 while the door 2 is locked and closed. In the second mode, the clasp driving by the knob 80 is impossible, and further, the clasp 20 driving through the button unit 90 or the user authentication unit 91 becomes impossible.

Further, in a state in which a signal corresponding to that the moving member 70 is disposed at the pressure release position, a signal corresponding to the opening of the door, and a signal corresponding to the unlocking of the door are input, the control unit 95 is configured to authenticate the user. If it is made by the authentication unit 91 can operate the motor 85 to drive the clamp 20, it is possible to lock the door (2). However, even if the button unit 90 is pressed, the control unit 95 does not operate the motor 85, so that the door maintains the unlocked state. As such, when the moving member 70 is disposed at the pressure release position and the unlocked door 2 is opened in the third mode, the user drives the moving member 70 while the door is unlocked and opened. Three modes can be set, and in the third mode, the clasp 20 can not be driven by the button unit 90, but the clasp can be driven by the user authentication unit 95, and the clasp can be driven by the knob.

On the other hand, the user may carry a separate remote control and use the remote control to unlock the door by operating the motor even when the door lock device is set in the second mode or the third mode.

Hereinafter, the operation mechanism of the door lock device 100 configured as described above will be described.

As shown in FIG. 1, when the door 2 is locked and the moving member 70 is disposed at the pressure release position and the locking member 60 is disposed at the locking position, unlocking the door from the indoor side of the door. In order to rotate the knob 80, the pressing portion 42 of the first driving member sequentially presses the inclined portion 314 and the pressurized portion 315 of the pressing member, so that the pressing member 40 is shown in FIG. To the spaced apart position. If the knob is continuously rotated thereafter, the first driving member 40 presses the pressing part 32 of the pressing member, so that the first driving member 40 and the pressing member 30 rotate together, as shown in FIG. 10. Are placed in a state. However, even if the pressing member 30 rotates the knob 80 in this state to press the inner surface of the pressing groove 22 of the clamp, the locking portion 61 of the locking member is caught by the locking jaw 23 of the clamp. Since the locked state continues to be maintained, the clamp 20 cannot be retracted. Thus, the locked state of the door is maintained.

On the other hand, in the state shown in Figure 1, holding the holding element 71 of the moving member and moving the moving member 70 to the left, the moving member is disposed in the pressing position shown in Figure 17, the locking member 60 Is placed in the locking position. Therefore, when the knob 80 is rotated, the pressing member 30 presses the inner surface of the pressurized groove 22 of the clamping body after the pressing member 30 linearly moves to a spaced apart position as described above, thereby releasing the locking of the door. When the knob 80 is released after the door 2 is unlocked, the elastic force of the compression coil spring acts, so that the pressing member moves back to the reference position. In particular, since the first driving member 40 and the second driving member 50 are coupled to rotate relatively, the second driving member 50 maintains a stopped state when the first driving member 40 is rotated.

As described above, in the present embodiment, when the knob 80 is rotated to lock or unlock the door 2, the second driving member 50 does not rotate, so that the motor 85 is not overloaded. The service life of the motor is increased, and furthermore, less power is required to rotate the knob 80, thereby increasing convenience of use.

In the state shown in FIG. 1, when the motor 80 is operated using the button unit 90 or the user authentication unit 91, and the second driving member 50 is rotated in the clockwise direction, the second driving member 50 is rotated. The first pressing protrusion 52 of the drive member rotates the pressing member by pressing the pressing portion 32 of the pressing member from the moment shown in FIG. 13, whereby the pressing portion of the pressing member 22 is the pressed groove 22 of the clamp. Press the inner surface. In addition, when the second driving member 50 rotates from the position shown in FIG. 1 to the position shown in FIG. 13, the third pressing protrusion 54 of the second driving member is configured to press the pressurized part 62 of the locking member. By pressing, the locking member 60 is rotated in the counterclockwise direction, thereby releasing the locking between the pressing member 62 of the locking member and the locking jaw 23 of the clamp. As a result, the second driving member 50 first presses the locking member in the rotation process to position the locking member 60 in the locking prevention position, and then presses the locking key to retract the locking clamp 20 as shown in FIG. 14. Let's do it. Therefore, even when the locking member 60 is located at the locking position, the door can be unlocked by driving the second driving member 50. On the other hand, when the door 2 is unlocked, as shown in FIG. 14, when the knob is rotated to rotate the first drive member 40 counterclockwise, the pressure member is pressed by the first drive member. And pressurizes the inner surface of the pressurized groove portion 22 of the clamp after moving to a spaced position, so that the clamp can protrude with respect to the indoor housing 10 as shown in FIG. Of course, even when the second driving member 50 is rotated counterclockwise in the state shown in FIG. 14, the second pressing protrusion 53 of the second driving member pressurizes by pressing the pressing part 32 of the pressing member. The member also rotates in a counterclockwise direction, and the pressing portion 32 of the pressing member presses the inner surface of the pressurized groove portion 22 of the clamp, so that the clamp 20 can protrude from the interior housing 10.

In addition, in the door lock device 100 of the present embodiment, the user can easily select the first mode, the second mode, and the third mode by driving the moving member 70. The first mode is a mode in which the door lock device operates normally with the movable member 70 in a normal state. In addition, the second mode is a mode in which the clasp driving by the motor 85 is basically blocked, and when the authentication method through the user authentication unit is exposed, for example, the user authentication unit 91 is configured as a keypad, but the password is exposed. Even if it is, the intruder who intrudes from the outside of the door 2 cannot unlock the door by inputting a password. In addition, when the user selects the third mode and closes the door again, the door lock device is automatically locked, and an intruder who intrudes through a window or the like can lock the door even when using the button unit 90 or the knob 85. Since there is no, the security of the door lock device is improved. In the present embodiment, when the locking door 20 is closed again, the locking mechanism 20 protrudes, so that the door is locked again, that is, the automatic locking configuration is already well known, and thus a detailed description thereof will be omitted. As described above, in the present embodiment, the door lock device can be easily changed to the first mode, the second mode, and the third mode as needed, and thus the user can easily select the advantages of each mode. In particular, in the first mode, the locking of the door can be released only by the rotation of the knob, so that a panic function can be implemented, thereby minimizing human injury in an emergency. Then, when the door is locked in the second mode and the third mode, the intruder who invades the indoor side is prevented from opening the door in the normal way and escaping.

Meanwhile, in the present embodiment, the first driving member is configured to be linearly movable between the reference position and the separation position, but the first driving member may be configured to only rotate the motion without linearly moving between the reference position and the separation position. have. As described above, when the first driving member only rotates, the inclined portion is not formed on the inner side of the insertion groove of the pressing member, and the pressurized portions are directly connected to both sides of the horizontal portion. The first driving member and the pressing member can rotate together by the pressing portion of the member directly pressing the pressed portion.

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 second driving member is configured to be driven by the rotational force of the motor, but the second driving member may be configured to linearly move by the operation of the solenoid. In this case, it is preferable that a power transmission unit including a plurality of links is installed between the solenoid and the second driving member. In addition, a power transmission unit for converting the linear movement force of the solenoid into the rotational force is provided, it is also possible to configure the second drive member to rotate during operation of the solenoid.

In addition, in the present embodiment, the clasp is configured to move linearly in the horizontal direction, but the clasp may be configured to move linearly in the vertical direction. In addition, the clasp may be configured to perform horizontal linear movement and vertical linear movement together or horizontal linear movement and rotation together.

In addition, although the knob is provided as an operation member for driving the first driving member in the present embodiment, it may be configured to include a linear driving member coupled to the housing in addition to the knob. In this case, a power converting means for converting the linear driving force of the linear driving member to the rotary driving force for rotating the first driving member should be provided. Since the power conversion means is widely known in other technical fields as well as the door lock device, a detailed description thereof will be omitted.

In addition, in the present embodiment, a digital door lock apparatus using a motor, a user authentication unit, etc. is disclosed, but may be configured as a mechanical door lock apparatus. In this case, the outdoor housing is not provided with an authentication unit, and the outdoor housing is rotatably coupled to the key bundle rotating body which rotates in association with the rotation of the inserted key. Then, the key assembly rotating body is linked to the rotation of the second drive member is connected to rotate.

In addition, the present embodiment discloses a door lock device in the form of an auxiliary key in which the handle is not rotatably coupled to the outdoor housing and the indoor housing.
