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.

Connected to the catch so that the catch moves in a direction immersed with respect to the housing in association with rotation in an opposite direction, the straight line between a reference position and a spaced apart position away from the reference position in the direction of the center of rotation relative to the housing; A movable pressing member; The pressing member is coupled to the housing so as to be rotatable with respect to the housing, and rotates relative to the pressing member within a predetermined relative rotation angle range and rotates together with the pressing member within an angle range outside the relative rotation angle range. Is connected to, and when the rotation within the relative rotation angle range presses the pressure member so that the pressing member moves linearly from the reference position to the spaced apart position, the rotation within an angle range outside the relative rotation angle range A first driving member pressurizing the pressing member so that the pressing member rotates in the direction in which the pressing member is pressed; And a second drive coupled to the housing so as to be rotatable or linearly movable relative to the housing, and pressurizing the urging member such that the urging member rotates in a direction in which the urging member presses the clamping lever in association with the rotational or linear movement of the housing. And the pressing member is disposed away from the rotational or linear movement path of the second driving member at the separation position, and the pressing member is disposed on the rotational or linear movement path of the second driving member at the reference position. The first driving member is pressed by the second driving member when the stopper is moved in a direction protruding and immersed with respect to the housing in association with the rotation or linear movement of the second driving member. It is pressed by the member and characterized by rotating.

Are arranged sequentially so as to form an angle of 90 °.

The pressing member 60 drives the rotation of the first rotating member 30 and the second rotating member 40. That is, when the pressing member 60 is rotated in one direction, for example clockwise in the state shown in Figure 2, the first pressing portion 611 and the second pressing portion 621 is the blood of the first rotating member, respectively Since the pressing part 33 and the pressurized part 52 of the intermediate rotating member are pressed, the first rotating member 30 and the second rotating member 40 rotate in a direction away from each other and are shown in FIG. 8. The door 1 is unlocked as is. Meanwhile, in the state shown in FIG. 8, the pressing member 60 rotates in a direction opposite to one direction, for example, counterclockwise, and the second pressing portion 621 and the third pressing portion 631 each rotate first. Since the member to be pressurized 33 and the member 52 to be pressurized are rotated, the first rotating member 30 and the second rotating member 40 rotate in a direction approaching each other, respectively. The door 1 is locked as shown in FIG.

On the other hand, the body portion 64 of the pressing member is formed with a through hole 641 and a pair of insertion grooves 642 disposed at both sides of the through hole 641, respectively.

The pair of inclined portions 644 are disposed to be spaced apart from each other by a predetermined distance, and are formed to be inclined with respect to the linear movement direction of the pressing member 60, respectively, and face-symmetric. In the present embodiment, the inclined portion 644 is formed in a convex curved shape, but is not necessarily limited to this, the pressing portion of the first driving member such as a plane inclined with respect to the linear movement direction of the pressing member 60 ( 72 may be any shape as long as the pressing member 60 is configured to linearly move to a spaced position. In addition, a pair of pressurized portions 65 are disposed on the inner surface of each insertion groove portion 642, respectively. The pair of pressurized parts 65 are respectively connected to a pair of inclined parts 644, the pair of pressurized parts 65 face each other, and the normal vector of each pressurized part 65 is a horizontal part. Orthogonal to the normal vector of (643).

The first driving member 70 is rotatably coupled to the indoor side housing 10. The first driving member 70 includes a pivot portion 71 and a pair of pressing portions 72.

The pivot portion 71 is rotatably inserted into the through hole 641 formed in the body portion 64 of the pressing member. The pivot portion 71 becomes a rotation center of the first driving member 70. The first driving member 70 is disposed coaxially with the pressing member 60.

The pair of pressing portions 72 are formed to protrude from the pivot portion 71, respectively. The protruding directions of the pair of pressing portions 72 face in opposite directions to each other, and the pair of pressing portions 72 constitute 180 °. The pair of pressing portions 72 are inserted into the insertion groove portions 642 of the pressing member, respectively, as shown in FIG. Each pressing portion 72 is disposed between the pair of inclined portions 644 in the insertion groove portion 642.

The first driving member 70 rotates relative to the pressing member 60 within a predetermined relative rotation angle range. That is, in the state shown in FIGS. 5 and 6, when the first driving member 70 rotates clockwise, the pressing portion 72 of the first driving member is shown in FIGS. 11 and 12. The first driving member 70 rotates relative to the pressing member 60 until the moment of contact with the pressurized member 65 of the pressing member. As described above, while the first driving member 70 relatively rotates, the pressing portion 72 of the first driving member presses the inclined portion 644 of the pressing member, so that the pressing member 72 is shown in FIGS. 10 and 12. Move to the spaced position as shown in When the first driving member 70 continues to rotate clockwise even after the pressing portion 72 of the first driving member contacts the pressure portion 65 of the pressing member, the pressing portion of the first driving member Since the 72 is to press the to-be-pressed portion 65 of the pressing member, the pressing member 60 is rotated clockwise like a body together with the first driving member 70 in a state in which it is disposed at a spaced apart position. Meanwhile, even when the first driving member 70 rotates counterclockwise in the state shown in FIG. 5, the first driving member 70 and the pressing member 60 operate in the same manner as described above. That is, the first driving member 70 moves relative to the pressing member 60 and the pressing member 60 until the pressing portion 72 of the first driving member contacts the pressurized portion 65 of the pressing member. The position of the first driving member 70 is rotated counterclockwise even after the pressing portion 72 of the first driving member is in contact with the pressurized portion 65 of the pressing member. 70 and the pressing member 60 is rotated together. As described above, the first driving member 70 has a predetermined relative rotation angle range, that is, the pressing portion 72 of the first driving member rotates clockwise or counterclockwise in the insertion groove 642 to be pressed. Relatively rotates with respect to the pressing member 60 within the angle range before contacting with), and rotates with the pressing member 60 when it exceeds the relative rotating angle range.

Then, after the first driving member 70 rotates out of the relative rotation angle range and rotates together with the pressing member 60, the pressurized portion 65 of the pressing member by the pressing portion 72 of the first driving member. When the pressure is released, the pressing member 60 is linearly moved toward the reference position by the elastic force on the compression coil spring 66, and in the process, the pressing portion 72 of the first driving member is inclined portion of the pressing member. It is disposed between the pair of inclined portions 644 in a direction opposite to the direction in which it has rotated with the pressing member 60 while being in contact with 644, for example, as shown in FIG. 11. As a result, since the pressurization by the first drive member 70 is always released after the first drive member 70 is operated, the pressing portion 72 of the first drive member is independent of the locked state of the door 1. It is disposed between the pair of inclined portion 644 formed in the pressing member.

On the other hand, the first driving member 70 is connected to the knob 75. The knob 75 is rotatably coupled to the indoor housing 10, and is coupled to the first driving member 70 to rotate together as a body. A knob 751 is formed with a handle 751 for the user to grasp and turn to drive the clamp 20. The knob portion protrudes from the knob body 752 and is formed in a substantially rectangular shape. The handle portion 751 is set so that its longitudinal direction is rotated by an angle to the right with respect to the vertical direction while the door is locked. In particular, in the present embodiment, the first driving member 70 and the knob 75 are formed in one body. When the knob 75 is rotated, the first driving member 70 rotates, and thus the pressing member 60 can be rotated along with the linear movement.

The second driving member 80 is rotatably coupled to the indoor housing 10. The second driving member 80 is fitted to the pivot portion 71 of the first driving member, and the second driving member 80 is disposed coaxially with the first driving member 70. The second driving member 80 has a plate-shaped portion 81 formed in a plate shape, a gear portion 82 formed in a circular shape at the edge of the plate-shaped portion 81, and composed of a plurality of teeth, and a plate-shaped portion ( 81 has a first pressing portion 83 and a second pressing portion 84 protruding in the thickness direction of the door 1. The gear portion 82 directly engages with the gear member 86 coupled to the output shaft of the motor 85, so that the second driving member 80 rotates when the motor 85 is operated. Here, the motor 85 operates when the user is authenticated by the authentication unit. The first pressing unit 83 and the second pressing unit 84 are arranged to be spaced apart from the rotation center of the second driving member 80 by a predetermined distance, and spaced apart by a predetermined distance along the rotation direction of the second driving member 80. Is placed. The first pressing part 83 is not in contact with the second extension part 62 as shown in FIG. 7 when the second driving member 80 rotates, but the first extension part 61 or the third extension part ( 63). That is, the vertical distance between the plate portion 81 and the first extension portion 61 and the vertical distance between the plate portion 81 and the third extension portion 63 are the second extension portion 62 from the plate portion 81. It is formed smaller than the vertical distance between. In addition, the emergency opening / closing protrusion 841 is formed in the second pressing part 84 in the same direction as the protruding direction of the second pressing part 84.

When the second driving member 80 is rotated with the pressing member 60 disposed at the reference position, the first pressing portion 83 and the second pressing portion 84 of the second driving member are formed of the pressing member. The pressing member 60 is rotated by pressing the first extension part 61 and the third extension part 63. For example, in the state shown in FIG. 3, when the second driving member 80 is rotated clockwise, the first pressing portion 83 and the second pressing portion 84 are respectively the third extension portion 63. And pressing the first extension portion 61 to rotate the pressing member 60 clockwise to release the locking of the door 1 as shown in FIG. 9. At this time, that is, when the pressing member 60 is pressed by the second driving member 80 to rotate, the pressing portion 72 of the first driving member is pressed in contact with the inclined portion 644 of the pressing member. , First driving member Rotate together, and eventually rotate the knob 75 that forms the body with the first driving member 70. do. In addition, although the pressing portion 72 is pressed by the inclined portion 644 when the pressing member 60 rotates, the pressing member 60 is elastically biased toward the reference position by the elastic force of the compression coil spring. When the rotation of the 80, the pressing member 600 is not moved to the spaced position.

On the other hand, when the second driving member 80 is rotated in a state where the pressing member 60 is disposed at a spaced apart position, the first pressing portion 83 and the second pressing portion 84 do not meet the pressing member 60. Only the emergency opening and closing protrusion 841 may meet the first extension part 61 or the third extension part 63 of the pressing member. In particular, when the second coil member 80 is rotated even in an emergency in which the pressurizing member 60 does not move to the reference position and is continuously disposed at a spaced position because of the reason that the compression coil spring 66 does not operate properly. , Ultimately, since the pressing member 60 may be pressurized by the emergency opening / closing protrusion 841, the door 1 may be locked or unlocked.

And in the door lock apparatus of this embodiment, you may comprise so that the key bundle rotating body 130 may be further provided. The key bundle rotating body 130 is rotatably coupled to the outdoor housing 110. The key ball rotating body 130 is formed so that the key hole 140 is exposed to the outside. A key corresponding to the shape of the key hole 140 is inserted into the key hole 140, and when the key inserted into the key hole 131 is rotated, the key bundle rotating body 130 rotates. The key bundle rotating body 130 is connected to the second driving member 80, and interlocked with the rotation of the key bundle rotating body 130 to rotate the second driving member 80 as well. Accordingly, when the key is inserted into the key hole 140 and rotated in the state shown in FIG. 3, the door 1 can be unlocked as shown in FIG. 9.

And, the member number 87 is an operation button installed in the indoor housing (10). When the operation button 87 is pressed, the motor can be rotated forward and backward, so that the door 1 can be locked or unlocked by rotating the second driving member 80.

In the door lock device configured as described above, when the knob 75 is rotated to unlock the door 1 in the state shown in Fig. 3, the pressing portion 72 of the first driving member is inclined portion of the pressing member. The pressure member 60 is rotated after the pressing member 644 is sequentially pressed to place the pressing member 60 at a spaced position, so that the pair of catches 20 move linearly in a direction away from each other. As shown in FIG. 8, the door 1 is unlocked. At this time, since the pressing member 60 does not come into contact with the second driving member 80 when the pressing member 60 rotates, the second driving member 80 maintains a stopped state.
