1 is a view showing the structure before operation of the door lock mortis according to an embodiment of the present invention. The door lock mortise 20 according to an embodiment of the present invention may include a dead bolt driving unit 300 for operating the dead bolt, a latch bolt driving unit 400 for operating the latch bolt, and a connection unit 200 .

The dead bolt driving unit 300 may include a first dead bolt operating gear 310 and a second dead bolt operating gear 320 . The first dead bolt operation gear 310 may have a cam member 315 . The cam member 315 may be integrally formed with the first dead bolt operation gear 310 . The cam member 315 may be seated on the seating part 250 of the connection part 200 to be described later. That is, the cam member 315 may be formed in a shape corresponding to the shape of the seating part 250 . The cam member 315 has a curved surface corresponding to the seating part 250 so that it can be smoothly removed when the connection part 200 rotates, and when the connection part 200 returns to its original position, it can be smoothly seated.

The cam member 315 may be connected to the seating part 250 disposed on the connection part 200 so that the first dead bolt operation gear slides and rotates as the connection part 200 rotates. The direction in which the first dead bolt operation gear 310 rotates may be clockwise or counterclockwise with respect to the hinge h1. In detail, the cam member 315 slides from the seating part 250 and can be separated in the opposite direction to the rotation direction of the connection part 200, and as the cam member 315 is separated, the first deadbolt operation gear 310 is can be rotated. The second dead bolt operation gear 320 may be connected to the first dead bolt operation gear 310 so as to rise according to the rotation of the first dead bolt operation gear 310 . As the second dead bolt operation gear 320 rises, the dead bolt 21 is drawn into the door lock mortis 20 to unlock the door lock state.

The latch bolt driving unit 400 has a restraining means 420 capable of maintaining the protruding state of the latch bolt and one end 410 on which the engaging unit 230 disposed on the connecting unit 200 is caught as the connecting unit 200 is rotated. may include Although the restraining means 420 and the one end 410 are distinguished as separate terms in this specification, the restraining means and the one end 410 may be integrally formed. In addition, in the present specification, the first locking part 230 and the second locking part 240 are illustrated and described, but the number is not limited and the latch 170 is rotated in any of the clockwise and counterclockwise directions. It is sufficient if the latch bolt 22 can be drawn in by operating the bolt driving unit 400 . The connection unit 200 may be positioned between the dead bolt driving unit 300 and the latch bolt driving unit 400 . In addition, it may be rotatably disposed, and the dead bolt driving unit 300 and the latch bolt driving unit 400 may be operated according to the rotation radius. The operation here is not only to directly transmit the force, but also separate components are appropriately arranged in a range that is easy for a person skilled in the art between the dead bolt driving unit 300 and the latch bolt driving unit 400 and the connecting unit 200 to operate. can mean to be

The connection unit 200 may include a first rotating body 210 and a second rotating body 220 . The first rotating body 210 The first rotating body 210 and the second rotating body 220 may be integrally formed, and for convenience of description, the terms may be arbitrarily used to distinguish them.

Locking parts 230 and 240 may be formed on the outer peripheral surface of the first rotating body 210 . The locking parts 230 and 240 may include a first locking part 230 and a second locking part 240 . The first locking part 230 and the second locking part 240 may be protrusions formed around the first rotating body 210 . Also, the shapes of the first locking part 230 and the second locking part 240 may be different from each other. In addition, the first locking part 230 and the second locking part 240 may be integrally formed and operated regardless of the rotational direction. However, hereinafter, for convenience of description, the case in which the two locking parts 230 and 240 are separately located on the outer circumferential surface of the first rotating body 210 will be described.

The first locking part 230 may operate the latch bolt driving part 400 through one end 410 when the connecting part 200 , that is, the first rotating body 210 is rotated in one direction. The second locking part 240 may operate the latch bolt driving part 400 through one end 410 when the connection part 200 , ie, the second rotating body 220 rotates. The principle of the first locking part 230 and the second locking part 240 operating the latch bolt driving unit 400 will be described later.

In addition, the connection part 200 may have a seating part 250 formed in a groove shape on the outer circumferential surface of the second rotating body 220 , and when the door lock motive 20 does not operate, the deadbolt driving part 300 of the first The cam member 315 of the dead bolt operation gear 310 may be in contact.

2 is a view illustrating a case in which a connection part is rotated in one direction in a door lock mortis according to an embodiment of the present invention.

Prior to the description, in this specification, with respect to the rotation direction of the connection unit 200, one direction is a case of clockwise rotation, and the other direction is described based on a case of rotating in a counterclockwise direction, but this is to help the understanding of the invention. It is clear that the name of the direction is only named, and the description of FIG. 2 to be described later does not apply only when it is rotated in a clockwise direction. That is, depending on the shape or internal structure of the door lock motive, the direction of rotation that the one direction and the other direction mean may vary, and this is commonly applied to the case described with reference to FIG. 3 as well.

Figure 2 (a) is a view showing when the connection part 200 is rotated by a first angle in the clockwise direction, Figure 2 (b) is a view showing when the connection part is rotated by a second angle in the clockwise direction . When the connection part 200 is rotated by a first angle in the clockwise direction, the cam member 315 of the first dead bolt operation gear 310 that is in contact with the seating part 250 disposed on the second rotation body 220 is It can slide away from the seating part 250 , and as the cam member 315 slides, the first dead bolt operation gear 310 can rotate counterclockwise around the hinge h1 . When the first dead bolt operation gear 310 rotates counterclockwise, the second dead bolt operation gear 320 may rise, and as the second dead bolt operation gear 320 rises, the dead bolt 21 may be introduced into the door lock mortis 20 . However, when the connecting part 200 rotates by the first angle, the first locking part 230 may only approach the latch bolt driving part 400 and may not directly transmit the rotational force.

The case in which the connection unit 200 rotates the second angle may refer to a case in which the connection unit 200 rotates by the second angle based on the initial state. That is, it may refer to a case in which the connection unit 200 rotates the first angle and further rotates by the difference between the second angle and the first angle.

When the connection part 200 rotates at a second angle in the clockwise direction, the first locking part 230 comes into contact with one end 410 of the latch bolt driving unit 400, and pushes up the one end 410 of the latch bolt driving unit 400 can be rotated. The latch bolt driving unit 400 may rotate in a counterclockwise direction with respect to the hinge h2. When the latch bolt driving unit 400 is rotated counterclockwise, the restraining means 420 holding the latch bolt 22 to protrude may move counterclockwise to descend. Therefore, before the operation of the latch bolt driving unit 400, the latch bolt 22 did not enter even with the restoring force of the elastic member 23 by the restraining means 420, but the restraining means is removed and the latch bolt 22 is the door lock motive 20 ) can be drawn inside.

When the door lock mortise 20 does not operate, the entry of the latch bolt 22 may be restricted by the restraining means 420 formed on the other side of the latch bolt driving unit 400 . The restraining means 420 may be integrally formed on the other side of the latch bolt driving unit 400 . The restraining means 420 may have a shape capable of maintaining the latch bolt 22 in a protruding state despite the restoring force of the elastic member 23 . In addition, when the restraining means 420 rotates, the restraining means 420 may be formed so as not to limit the entry of the latch bolt 22 . Accordingly, when the latch bolt driving unit 400 rotates, the latch bolt 22 may be drawn into the door lock mortis 20 by the restoring force of the elastic member 23 .

3 is a view showing a state in which the connection part of the door lock mortise rotates in another direction according to an embodiment of the present invention. 3 (a) is a view showing when the connection part 200 is rotated by a first angle in the counterclockwise direction, Figure 3 (b) is a view showing when the connection part is rotated by a second angle in the counterclockwise direction It is a drawing. When the connection part 200 rotates by a first angle in the counterclockwise direction, the first dead bolt operation gear 310 in contact with the seating part 250 disposed on the second rotating body 220 is the seating part 250 . It can slide away from the first dead bolt operation gear 310 and can rotate counterclockwise around the hinge h1 as the sliding gear 310 slides. When the first dead bolt operation gear 310 rotates counterclockwise, the second dead bolt operation gear 320 may rise, and as the second dead bolt operation gear 320 rises, the dead bolt 21 may be introduced into the door lock mortis 20 . However, when the connection part 200 rotates by the first angle, the second locking part 240 may only approach one end 410 of the latch bolt driving part 400 and may not directly transmit force.

When the connection part 200 rotates the second angle, the second locking part 240 may come into contact with one end 410 of the latch bolt driving part 400 . After the second locking part 240 and the one end 410 come into contact, the second locking part 240 may slide from the top to the bottom of the one end 410 . The second locking part 240 may lift the one end 410 while sliding from the top to the bottom of the one end 410 . That is, as the second locking part 240 slides from the top to the bottom of the one end 410 , the latch bolt driving part 400 may be rotated counterclockwise. The latch bolt 22 may be retracted while the latch bolt driving unit 400 rotates counterclockwise. Since the process in which the latch bolt 22 is retracted has been described above, it will be omitted.

The first angle and the second angle may be arbitrarily set by the designer, preferably in consideration of the user's convenience, and the first angle and the second angle of the first locking part 230 and the second locking part 240 are Since it can be determined according to the arrangement position, it can be freely determined. For example, when the first angle is set to about 15 degrees and the second angle is set to about 25 degrees, when the user or the motor rotates the connection part 200, the dead bolt 21 is released at about 15 degrees, and about If it moves further by 10 degrees, the latch bolt 22 may be released.

2 and 3, the door lock mortise 20 according to an embodiment of the present invention can be conveniently used regardless of the left or right. This is because the connection part 200 can be formed so that the dead bolt 21 and the latch bolt 22 can be drawn into the door lock motive even when the connection part 200 is rotated in any of the clockwise and counterclockwise directions.

4 is a perspective view of a digital door lock included in the digital door lock system according to an embodiment of the present invention. Referring to FIG. 1 , it is possible to grasp the state of the front and rear surfaces of the indoor part of the digital door lock, and it is possible to grasp where the components shown in FIGS. 5 to 8 can be located inside the digital door lock 10 .

The digital door lock 10 may automatically release the lock state of the dead bolt 21 and the latch bolt 22 by recognizing the user's intention to go out. At this time, various methods may be used as a method of unlocking the dead bolt 21 and the latch bolt 22 by identifying the user's intention to go out, and the method is not limited. For example, an IR sensor may be disposed to detect the movement of the human body to determine the user's intention to go out, and a PIR sensor may be preferably used. If the user's intention to go out is recognized by the above-described sensor, the digital door lock 10 can be put on standby in an operable state. When the digital door lock (10) is in operation standby state in an operable state, if you hold the handle placed on the door, the user is recognized through temperature, pressure or fingerprint, or a part of the human body approaches the handle and exists within a certain distance. If necessary, a method to unlock the dead bolt and latch bolt, or a signal to unlock the dead bolt and latch bolt inside the digital door lock 10 by pressing a button that can be disposed on the digital door lock 10 There are no restrictions on how to send

According to an embodiment of the present invention, the digital door lock 10 of the digital door lock system may not release the latch bolt by rotating or pushing and pulling the handle differently from the lever handle type or push/pull type door lock. The handle disposed on the door exists only for the convenience of opening and closing the door, and may have nothing to do with unlocking the latch bolt.

The digital door lock 10 shown in FIG. 4 may be a door lock installed indoors based on the door. The user may not need to re-authenticate when going out. This is because the door lock prevents intrusion from the outside and can be the primary means of protecting the body and property from external dangers, so there is no need to obtain authentication for the user who is already inside the room to go out. In addition, if authentication is performed for the user to escape in an emergency such as a robbery as well as a fire, earthquake, and natural disaster, it may cause inconvenience to the user as well as threaten the safety.

Therefore, the digital door lock 10 may have a structure capable of releasing the dead bolt 21 and the latch bolt 22 without a separate authentication procedure when the user goes out from the inside, ie, an anti-panic structure.

5 is an exploded front view of a digital door lock included in the digital door lock system according to an embodiment of the present invention, and FIG. 6 is a rear exploded view of the digital door lock included in the digital door lock system according to an embodiment of the present invention.

The digital door lock 10 may include a motor 110 , a link drive gear 120 , a link driven gear 130 , a shaft gear 140 , a thumb turn knob 150 , and a thumb turn gear 160 .

The motor 110 may rotate by converting electrical energy into mechanical force. According to the user's intention to go out, the dynamics that provide the driving force to release the dead bolt and latch bolt can be performed. An appropriate number of motors 110 may be disposed as needed, and although two are shown in FIG. 5 , the present invention is not limited thereto. As the number of motors 110 increases, the load applied to each motor may decrease, so that the number of advantageous motors 110 may be selected according to the user's convenience.

The link driving gear 120 and the link driven gear 130 may be referred to as a motor driving unit (not shown). However, the link driving gear 120 and the link driven gear 130 may not be integrally formed, and may be expressed as one word for convenience in describing the embodiments of the present invention. In addition, the motor driving unit may additionally include a separate part or configuration within a range that can be easily derived by a person skilled in the art other than the link driving gear 120 and the link driven gear 130 .

The link driving gear 120 rotates by receiving the rotational force transmitted from the motor 110 , and may serve to rotate the link driven gear 130 . The link driving gear 120 may be disposed so as not to be directly affected by the rotation of the thumb turn knob 150 when the thumb turn knob 150 is rotated. If an anti-panic structure is formed in which the user manually rotates the thumb turn knob 150 to release the lock state of the dead bolt 21 and the latch bolt 22, a greater force must be applied to turn it because a load to the motor is generated. This is because it may cause inconvenience to users. Therefore, the link driving gear 120 rotates based on the rotation axis of the thumb turn knob 150 in order not to be directly affected by the rotation of the thumb turn knob 150, but may be spaced apart so as not to be connected to the rotation shaft.

The link driven gear 130 may be disposed to mesh with the link driving gear 120 . In addition, the link driven gear 130 may have a protrusion 131 disposed on the outer circumferential surface. The protrusion 131 may be fitted into the groove 141 disposed on the shaft gear 140, and may be moved in the groove 141 according to the shape of the groove 141, and the protrusion 131 may be inserted into the groove ( When the link driven gear 130 rotates even after reaching the end of the 141 , the link driven gear 130 and the shaft gear 140 may rotate together.

The shaft gear 140 and the sum turn gear 160 may be referred to as a shaft driving unit. However, the shaft gear 140 and the sum turn gear 160 may not be integrally formed, and may be expressed as one word for convenience in describing embodiments of the present invention. In addition, in addition to the shaft gear 140 and the sum turn gear 160, the shaft driving unit may additionally include a separate part or configuration within a range that can be easily derived by a person skilled in the art.

The shaft gear 140 may be disposed to mesh with the sum turn gear 160 , and the shaft 170 may be a part connected to the digital door lock 10 . The shaft 170 may be connected to the mortise into which the dead bolt and the latch bolt may be introduced, so that the dead bolt 21 and the latch bolt 22 may be introduced into the mortise. Accordingly, as the shaft gear 140 rotates, the locked state of the dead bolt 21 and the latch bolt 22 may be released. That is, when the shaft driving unit connected to the thumb turn knob 150 and rotating the shaft connected to the connection unit 200 is driven, the shaft 170 rotates, and the dead bolt and the latch bolt are locked by the rotation of the shaft 170 . can be turned off. As described above, the groove 141 may be formed in the shaft gear 140 , and the protrusion 131 formed in the link driven gear 130 may be fitted. A rotation angle at which the link driven gear 130 and the shaft gear 140 can rotate independently of each other may be determined according to the shape of the groove 141 . When the rotation is more than a predetermined rotation angle, the link driven gear 130 and the shaft gear 140 may rotate together. In addition, as will be described later, when the sum turn gear 160 rotates according to the rotation of the sum turn knob 150 and the shaft gear 140 meshed with the sum turn gear 160 rotates, the protrusion 131 and the groove 141 . A shape that does not affect the link driven gear 130 may be selected. That is, the shape of the groove 141 may vary depending on various factors such as the user's convenience or the size of the digital door lock 10 .

The shaft gear 140 does not need to be arranged so that the link driven gear 130 and the outer peripheral surface are in contact. However, if the shaft gear 140 and the link driven gear 130 rotate based on the same rotation axis, the rotation angle at which the protrusion 131 of the link driven gear 130 moves inside the groove 141 of the shaft gear 140 . There may be fewer restrictions in selecting

The sum turn knob 150 corresponds to a handle for rotating the sum turn gear 160 by a user applying a physical force.

7 is a view showing the inside of the digital door lock when the digital door lock included in the digital door lock system according to an embodiment of the present invention operates normally. The progress of unlocking the lock state and returning to the original state of the digital door lock 10 can be identified by arranging in the order of FIGS. 7 (a), 7 (b), 7 (c) and 7 (d).

Figure 7 (a) shows a neutral state in which the locked state of the digital door lock 10 of the digital door lock system according to an embodiment of the present invention is maintained. In Figure 7 (a), it is expressed that the motor 110 rotates in a counterclockwise direction, but it is not limited thereto, and it is revealed that the rotation direction can be selected differently depending on the internal structure of the digital door lock 10, and in the present specification, the operation In describing the principle, it will be described based on the bar shown in the drawings for convenience.

When the digital door lock 10 detects the user's intention to go out, the motor 110 is driven and the motor 110 may rotate counterclockwise. The rotational force generated from the motor 110 may rotate the link driving gear 120 clockwise. Since the link driving gear 120 rotates in the clockwise direction when the motor 110 rotates in the counterclockwise direction, there may be a gear directly receiving the rotational force from the motor 110 in the drawing. However, the present invention is not limited thereto. In transmitting the rotational force generated by the motor 110, there is no limitation, such as a method through a gear and a method that is directly connected to transmit the rotational force.

Referring to FIG. 7B , the link driving gear 120 is meshed with the link driven gear 130 . Accordingly, the link driven gear 130 rotates together as the link driving gear 120 rotates. In the neutral state, the protrusion 131 of the link driven gear 130 is inserted into the end of the groove 141 of the shaft gear 140, so that when the link driven gear 130 rotates, the shaft gear 140 also rotates accordingly. do. Since the shaft gear 140 can mesh with the sum turn gear 160, as the shaft gear 140 rotates, the sum turn gear 160 rotates, and the sum turn gear 160 is connected to the sum turn knob 150, The thumb turn knob 150 also rotates. When the shaft gear 140 rotates, the shaft 170 connected to the shaft gear 140 can rotate, and since the shaft 170 is connected to the mortis, the dead bolt 21 and the latch according to the rotation of the shaft 170 are rotated. The lock state of the bolt 22 can be released.

Referring to FIG. 7( c ), when the user's entry/exit action is finished, the motor 110 may rotate the link driving gear 120 counterclockwise again. The link driven gear 130 capable of meshing with the link driving gear 120 may rotate clockwise as the link driving gear 120 rotates counterclockwise. At this time, the protrusion 131 of the link driven gear 130 may be disposed at one end of the groove 141 disposed on the shaft gear 140, and as shown in FIG. Accordingly, when moving from one end of the groove 141 to the other end, it can rotate separately from the shaft gear 140 . If the link driving gear 120 continues to rotate even after the protrusion 131 formed on the link driven gear 130 reaches the other end of the groove, the shaft gear 140 also rotates clockwise, and accordingly, the sum turn gear 160 ) also rotates counterclockwise. When the sum turn knob 150 returns to the neutral state, the motor 110 rotates the link driving gear 120 clockwise again, so that the protrusion 131 disposed on the link driven gear 130 becomes the shaft gear 140 . It can be moved from the other side to one end, and through this process, the internal gears of the digital door lock 10 can be made to be arranged in a neutral position as shown in FIG. 4(d).

8 is a view showing the inside of the digital door lock included in the digital door lock system according to an embodiment of the present invention when manually operating the thumb turn knob.

Figure 8 (a) shows a state in which all of the internal gears are arranged in a neutral position as shown in Figure 7 (a). In case of moving from inside to outside, separate authentication is not required, so a simple anti-panic structure may be required. The user can release the lock state of the dead bolt 21 and the latch bolt 22 by rotating the thumb turn knob 150 disposed on the digital door lock 10 .

Specifically, when the user rotates the sum turn knob 150, the sum turn gear 160 rotates, and when the sum turn gear 160 rotates, the shaft gear 140 meshed with the sum turn gear 160 rotates. do. As the shaft gear 140 rotates, the locked state of the dead bolt 21 and the latch bolt 22 may be released.

More specifically, when the sum turn gear 160 rotates in a clockwise direction, the shaft gear 140 rotates in a counterclockwise direction. Since the groove 141 is disposed in the shaft gear 140 and the protrusion 131 of the link driven gear 130 is disposed at one end, the shaft gear 140 until the protrusion 131 moves to the other end. is not affected by the rotation of Accordingly, the link driven gear 130 does not rotate and thus does not apply a load to the motor 110 . In addition, when rotating the sum turn knob 150, the rotation angle of the shaft gear 140 may be smaller than the rotation angle of the sum turn gear 160. Therefore, the user rotates the thumb turn knob 150 with a small force to rotate the dead bolt 21 ) and the latch bolt 22 can be unlocked.
