Description

Digital door lock}

The present invention relates to a digital door lock.

Particularly, the present invention is characterized in that the number of cases in which gears are damaged by eliminating the coupling relationship between the dead lever and the drive module when the indoor handle is operated is eliminated. In the case where the auxiliary dead lever is forcibly operated by the emergency key, The present invention relates to a digital door lock having a second feature in that an emergency key can be smoothly operated by releasing a coupling relationship between a lever and a drive module.

Generally, a digital door lock can be opened by using a button-type or a touch-type key in place of the conventional method of locking or opening the door using an insertion key, and automatically opening the door when the door is closed It is an electronic door lock system that locks the door. It has the advantage of simplifying the process of opening or locking the door in comparison with the conventional door lock system, and enhancing the security function.

These digital door locks have a double locking structure with automatically activated deadbolts and manually operated latch bolts. In addition, the dual lock status of the dead bolt and latch bolt can be released at the same time when the inside handle is operated. There is also an early panic function.

1 to 3 are schematic perspective views of a general digital door lock having a panic function, which is a perspective view taken from the main part of the Korean Patent Registration No. 10-543831 (Prior Document 1).

1, the interior door handle 1, the connecting pin 3, and the inner latch lever 5 are interconnected and interlocked with each other, and the outdoor handle (not shown) 7, the connecting shaft 9, and the outer latch lever 11 are interconnected and interlocked.

In order to open the digital door lock on the outdoor side, when the electronic key is used or a password is inputted, the dead bolt 13 protruding out of the case as shown in Fig. 2 is inserted into the case by the dead lever 17 The latch bolt 15 protruding out of the case is also immersed into the case by the outer latch lever 11. As a result, when the door 7 is rotated, So that it can be opened. That is, on the outdoor side, the dead bolt 13 and the latch bolt 15 are individually operated.

On the other hand, when the interior handle 1 is rotated in one direction on the indoor side, the inner latch lever 5 and the dead lever 17 are interlocked as shown in Fig. 3, and the dead bolt 13 and the latch bolt 15 The door is immersed in the case, thereby exhibiting a panic function capable of opening the door by only one operation, so that it can be quickly evacuated to the outside in case of emergency.

On the other hand, a driving means of the dead lever 17 is disclosed in Korean Patent Registration No. 10-0543829 (Prior Document 2).

Although not shown separately in this application, the dead-lever drive means disclosed in the preceding document 2 includes a drive motor incorporated in the case, a drive gear coupled to the shaft of the drive motor and rotated in normal and reverse directions, A second driven gear meshed with the first driven gear, a third driven gear meshed with the second driven gear, and a second driven gear meshed with the third driven gear and integrally formed with the dead lever And a fourth type synchronous word.

According to this configuration, when the drive motor is operated, the dead lever integral with the fourth driven gear rotates as the drive gear and the first to fourth driven gears in the interconnection relationship rotate in a chain, The dead bolt connected to the lever is linearly moved to perform locking and opening actions.

However, since the above-mentioned conventional dead-lever drive means keeps the gears always engaged with each other, the following problems may arise.

For example, when the user operates the indoor knob during the process of operating the dead bolt, the gears between the drive motor and the dead lever may be damaged.

Specifically, for example, when the deadbolt is immobilized by the drive motor, when the indoor knob is operated, the dead bolt is operated in the direction in which the dead bolt is drawn out. Therefore, if the gears are rotated by the driving motor in the direction in which the dead bolt is immersed (forward), when the indoor knob is operated, the gears are subjected to a load in the reverse direction, which causes a gear breakage.

As another example, if the digital door lock becomes inoperable due to a fault, the dead bolt must be forcibly operated using the emergency key. In this case, when the emergency key is inserted into the keyhole formed in the dead lever and rotated, the deadbolt can be forcibly operated while the dead lever rotates.

However, since each of the above-mentioned gears is directly or indirectly connected to the stopped drive motor, if the dead lever is forcibly operated, a load is applied to the gears to shorten the service life and difficulty in forcibly operating the dead lever there was.

A main object of the present invention is to provide a digital door lock in which a number of cases where a gear is damaged by disengaging a coupling relation between a dead lever and a drive module when operating an interior handle is provided have.

In addition, the present invention provides a digital door lock capable of reducing a load applied to a gear and smoothly operating an emergency key by disengaging the coupling relationship between the main dead lever and the drive module when the auxiliary dead lever is forcibly operated by the emergency key .

The dead bolt 200 is horizontally installed on the upper side of the case 100 so as to protrude and retract from the case 100. This deadbolt 200 is the main locking element of the digital door lock.

The main dead lever 300 is rotatably supported in the case 100 and receives power from the drive module 700 to linearly move the dead bolt 200.

The latch bolt 400 is installed inside the case 100 so as to protrude in the same direction as the dead bolt 200 while being disposed below the dead bolt 200.

The panic lever 600 is rotatably supported inside the case 100. The panic lever 600 can be operated by the outside handle not shown by itself or by the handle lever (not shown) 500 and the main dead lever 300 at the same time. The specific configuration thereof will be described later.

The drive module 700 serves to provide rotational power to the main dead lever 300 in a forward or reverse direction. Its specific configuration will be described later.

From this configuration, the main feature of the present invention is to improve the configuration of the main dead lever 300, the panic lever 600, and the drive module 700 to prevent the gear failure.

The improved structure is as follows.

First, the main dead lever 300 includes a cylindrical case 310 and a key block 320, as shown in FIG.

A lever portion 311 is formed at one side of the outer circumferential surface of the cylindrical case 310 so as to be fitted into a connection groove 210 of the dead bolt 200 An idle dead gear gear 312 is formed on the main surface of the cylindrical case 310 and an operation protrusion 313 is integrally formed on the circumferential surface of the cylindrical case 310.

The lever portion 311 serves as a connector for connecting the cylindrical case 310 to the main dead lever 300 and the dead lever gear 312 is connected to the driven gear of the drive module 700 The actuating protrusion 313 serves to rotate the auxiliary dead lever of the panic lever 600 (to be described later). The actuating protrusion 313 rotates the cylindrical case 310 by the power provided from the driving module 700, So that the cylindrical case 310 rotates in conjunction with the rotation of the auxiliary dead lever.

Further, the cylindrical case 310 has a protrusion 314 formed at one end (right end in the drawing). The protrusion 314 is inserted into the groove of the key block 320 to be described later.

The key block 320 has a cylindrical shape loosely inserted into the cylindrical case 310 as shown in FIG. Therefore, the inner case 310 is rotatable.

In addition, the key block 320 has a key groove 321 formed at its central portion in the axial direction. When the digital door lock is in a disabled state, the key groove (321) inserts the emergency key to forcibly rotate the key block (320), and the cylindrical case (310) and the main dead lever ) To be forced to operate.

The key block 320 has a flange portion 322 formed at one end (right end in the drawing) of the key block 320 to be in contact with one end (right end in the drawing) of the cylindrical case 310.

The key block 320 has an arcuate groove 323 in which the protrusion 314 is inserted on a surface of the flange portion 322 which is in contact with one end of the cylindrical case 310. Here, the protrusion 314 can flow within the length of the groove 321.

A semi-moon shaped groove 324 is formed on the outer circumferential surface of the flange portion 322 of the key block 320 to selectively contact the surface of the driving module 700.

The main dead lever 300 described above is an important component of the protrusion 314 formed in the cylindrical case 310 and the grooves 323 and recesses 324 formed in the key block 320. The necessity of this configuration will be described later.

Next, the panic lever 600 has a configuration in which the latch lever 500 and the auxiliary dead lever 610 are coaxially combined as shown in Fig.

The latch lever 500 is for operating the latch bolt 400, and a pair of the latch bolt 500 is arranged coaxially.

The auxiliary dead lever 610 is coaxially disposed between the pair of latch levers 500 and rotates the cylindrical case 310 by pushing the operation protrusion 313 of the main dead lever 300 when the auxiliary dead lever 610 rotates It plays a role.

Here, among the pair of latch levers 500, the latch lever disposed on the outdoor side is coupled to an outdoor handle (not shown), and the latch lever and the main dead lever 300, which are disposed on the indoor side, Time. Therefore, when the outdoor knob is rotated, only the latch lever disposed on the outdoor side rotates, and when the indoor knob is rotated, the latch lever and the main dead lever 300 disposed on the indoor side can be simultaneously operated. This is a convenient function that allows the door to be opened quickly in the room by allowing the dead bolt 200 and the latch bolt 400 to be immersed at once as a panic function as described above.

Particularly, part of the contact area of the auxiliary dead lever 610 with the drive module 700 is provided with auxiliary dead lever 610 A pushing protrusion 611 for pushing the drive module 700 in a direction in which the dead lever gear 312 and a driven gear (to be described later), which is an accessory of the drive module 700, are separated from each other is formed.

The push projection 611 is an important component of the panic lever 600, and the necessity of this configuration will be described later.

Next, the drive module 700 has a housing 710 disposed at a lower side of the case 100, as shown in FIG.

Here, the housing 710 is installed to flow from the dead lever gear 312 in a direction in which the driven gear, which will be described later, is spaced apart, as shown by the arrow in FIG. In the embodiment of the present invention, the lower portion of the housing 710 is configured such that the upper portion of the housing 710 is rotated from the hinge axis h.

The housing 710 is elastically supported by a spring 720 at a position opposite to the direction in which the housing 710 is separated from the dead lever gear 312. The spring 720 exerts an elastic force to push the upper portion of the housing 710 toward the dead lever gear 312.

Further, the driving module 700 has a driving motor 730 disposed at an inner lower portion of the housing 710.

The driving module 700 has a worm gear type driving gear 740 coupled to the shaft of the driving motor 730.

The drive module 700 has one or more driven gears 750 that are housed in the upper portion of the inside of the housing 710 and engage with the drive gear 740. In the present invention, two driven gears are shown as an example.

Hereinafter, the operation of the digital door lock according to the present invention will be described. The operation of the main dead lever 300, the panic lever 600, and the drive module 700 will be mainly described.

First, referring to FIG. 8, the operation of the panic lever 600 will be described.

When the main body deadbolt 300 is rotated by the driving module 700 and the deadbolt 200 is pulled out, when the indoor handle is rotated, the latch lever 500 of the panic lever 600 and the auxiliary dead lever The main dead lever 300 is rotated in the clockwise direction in the drawing as the main dead lever 300 pushes the operation protrusion 313 as shown in the lower view of FIG. The connected dead bolts 210 are forcibly moved in the immersion direction on the right side in the figure.

That is, the pulling direction of the deadbolt 210 by the driving module 700 and the pulling-in direction of the deadbolt 210 by the indoor knob are operated in opposite directions to each other so that the dead lever gear 312, the driven gear 750, It may act as a large load to the gear 740 and cause gear failure.

8, since the auxiliary protrusion 611 is formed on the contact surface of the auxiliary dead lever 610 with the driving module 700, the auxiliary dead lever 610 rotates, (611) pushes the driving module (700). Accordingly, the driving module 700 rotates in the clockwise direction (arrow direction) as viewed from the hinge axis h, and the subsidiary gear 750, which is an appendage thereof, is separated from the dead lever gear 312, The power to the motor 210 is cut off.

Thus, the dead bolt 210 is released from the restraint of the drive module 700, and is operated only by the panic lever 600, so that the damage to the gear can be prevented.

On the other hand, the rotated driving module 700 is returned to its home position by the elastic force of the spring 720. [

Next, a case where the main dead lever 300 is operated manually will be described with reference to FIG.

9, when the key block 320 is rotated clockwise in the drawing after the emergency key is pulled into the key groove 321 of the key block 320, as shown in the middle diagram of FIG. 9, The groove 324 formed on the outer peripheral surface of the flange portion 322 of the drive module 700 is released from the contact state with the outer surface of the drive module 700 and the outer peripheral surface of the flange portion 322 comes into contact with the outer surface of the drive module 700, The module 700 is rotated in the left-hand direction in the figure from its hinge axis h as its starting point. As a result, the dead lever gear 312 and the driven gear 750 of the drive module 700 are separated from each other as shown in FIG. 8, so that the main dead lever 300 can be operated thereafter without interfering with gears .

9, when the protrusion 314 of the cylindrical case 310 is caught at the end of the groove 323 of the key block 320 in a state where the gear is separated from the key block 320, The dead bolt 200 can be smoothly operated by the lever portion 311 formed in the cylindrical case 310. [
