Hereinafter, an indoor unlocking type digital door lock according to the present invention will be described with reference to the accompanying drawings.

The present invention relates to an indoor unlocking type digital door lock that allows the door to be locked and unlocked. As shown in Figs. 1 to 5, only a user authorized from the indoor side unlocks the dead bolt 21 It includes an indoor unit (IB) that enables the indoor unit (IB), and a dead bolt operating means (20) for locking and unlocking the door (D) in connection with the security release of the indoor unit (IB).

In the present specification, a digital door lock in a form in which a mortise M having the dead bolt operating means 20 is embedded and installed inside the door D is representatively shown, but the mortise M is omitted like a glass door The present invention can also be applied to the digital door lock of, in this case, the dead bolt operating means 20 will be built into the indoor unit (IB).

The indoor unit IB is installed on one side of the interior of the door D like a conventional digital door lock,

However, while a conventional indoor unit is provided with a thumb-turn knob, an open button, and a panic handle, any indoor resident can open the door (D).

The indoor unit (IB) of the present invention does not have a thumb-turn knob, an open button, a handle for a panic function, etc., without contacting a security medium (card, tag, etc.), fingerprint recognition, password input, wired, wireless security release (wired to the management room). It is provided with one or more security release means (such as an open button, wireless remote control, etc.) connected to the motor 23 to release the dead bolt 21 by reversing the door when the security is released. ) To unlock and open.

The indoor unit (IB) includes a housing (10) installed in the door (D), and a PCB control board for operating the security releasing means, various electronic components, batteries, etc. are built into the housing (10). ,

In the drawings of the present specification, a first unlocking unit 11 to which a security medium (card key, etc.) comes into contact with the front portion of the housing 10, and a second unlocking unit 12 for performing fingerprint recognition are provided as security release means. An embodiment can be confirmed, and Jimin recognition can be added with a separate numeric button or a touch panel.

This security releasing means is connected to the control plate of the dead bolt operating means 20, and when the security is released, the motor 23 is operated so that the dead bolt 21 moves backward to unlock the door D, and the door D When closing is detected, the motor 23 automatically advances the dead bolt 21 again to lock the door D.

Meanwhile, the indoor unit IB includes key insertion holes 13 formed through both front and rear surfaces.

The key insertion hole 13 communicates with the hole provided in the housing of the door D and the mortise M, and the security key inserted into the key insertion hole 13 is an operating hole of the operation lever 25 to be described later ( When the user directly rotates the security key by being inserted into 25a), the operation lever 25 of the dead bolt operation means 20 is manually rotated and the door D is unlocked.

Next, the dead bolt operating means 20,

A motor 23 with a drive gear 22,

A driven gear 24 engaged in a bevel gear structure with the driving gear 22, and an operating lever that is connected to protrude from the driven gear 24 to one side and inserted into the locking groove 21a of the dead bolt 21 Including a turn knob unit 26 consisting of 25,

When the motor 23 is operated by the security releasing means, the dead bolt 21 moves backward while the operation lever 25 rotates.

First, the dead bolt 21 operates backwards and forwards so that the lock at the outer end appears to the outside of the mortise (M), locks and unlocks the door (D), and transmits the forward and backward power from the motor 23 An inverted triangle-shaped locking groove 21a with an open top surface is provided at the inner end for receiving.

Non-explained reference numeral 21b is a sensing unit that allows the detection sensor of the mortise (M) to detect the current position of the dead bolt 21, and the driving gear by the motor 23 according to the detected position of the dead bolt 21 ( 22) rotation direction is switched.

The motor 23 is mounted on the motor M so that the rotation shaft faces a vertical direction, and when the motor 23 is operated, the drive gear 22 provided on the rotation shaft rotates in both directions.

The turn knob unit 26 converts and transmits the rotational force of the motor 23 to the forward and backward motion of the dead bolt 21, and the driven gear 24 having a shaft hole 24A, and the shaft hole ( It consists of a two-piece structure consisting of an actuating lever 25 provided with a rotating shaft 25A that is fitted and axially coupled to 24A).

Specifically, the driven gear 24 is engaged so as to be aligned in a direction orthogonal to the gear portion of the driving gear 22, and transmits the rotational force of the motor 23 to the operation lever 25, thus in a bevel gear structure. The engaged drive gear 22 and the driven gear 24 reduce the number of power transmission parts and allow the gears to be arranged more compactly, thereby improving operational stability by the motor 23.

In addition, the driven gear 24 has a shaft hole 24A penetrating through the center of the gear portion, and a rotation shaft 25A of the operating lever 25 is inserted into the shaft hole 24A to be built.

The operating lever 25 receives the rotational force of the motor 23 and rotates together with the driven gear 24 or separately from the driven gear 24 through physical pressurization of a security key, so that the dead bolt ( 21) forward and backward.

This operation lever 25 includes an operation hole 25a in the center of the rotation shaft 25A in communication with the key insertion hole 13 to insert a security key,

It is possible to manually reverse the dead bolt 21 by using a security key indoors.

In addition, the turn knob unit 26 is provided with a moving groove 24a concavely formed in a predetermined length on a part of the inner circumferential surface of the shaft hole 24A, and protruding from the outer circumferential surface of the rotation shaft 25A to the moving groove 24a. ) And including a locking projection (25b) that is fitted to be in contact with one end of the.

The motor 23 operates to return to the original position by rotating in the other direction after the driven gear 24 rotates in one direction,

When unlocking using the security key, the dead bolt 21 moves backward while only the operation lever 25 is idle with respect to the driven gear 24.

Specifically, when explaining the operating mechanism of the dead bolt operating means 20,

First, as shown in FIG. 2, when the dead bolt 21 is advanced by the motor 23 and the door D is wound, the locking protrusion 25b is at one end of the moving groove 24a (left side in the drawing). It is hung on, and the operation lever 25 is caught in one end of the locking groove 21a to prevent the dead bolt 21 from reversing.

In addition, when an authorized user on the indoor side releases security by contacting the security medium of the indoor unit IB, fingerprint recognition, or inputting a password, the motor 23 operates and the drive gear 22 rotates.

The driven gear 24, which has received the rotational force from the driving gear 22, rotates in the other direction (counterclockwise in the drawing), and one end of the moving groove 24a moves the locking protrusion 25b in the other direction. And, accordingly, the operation lever 25 rotating in the other direction together with the driven gear 24 pushes the other end of the locking groove 21a, so that the dead bolt 21 moving backward as shown in FIG. The door (D) is unlocked by entering the interior of the mortise (M).

And when the door (D) is closed after the door (D) is unlocked, the motor (23) operates again, and the driven gear (24), which has received the rotational force from the drive gear (22), moves in one direction. As shown in Fig. 4, the other end of the moving groove 24a pushes the locking protrusion 25b in one direction while the operation lever 25 pushes the other end of the locking groove 21a, thereby moving forward. The dead bolt 21 is pulled out of the mortise (M) to lock the door (D).

When the door (D) is locked, that is, when the dead bolt (21) is detected, the motor (23) is re-operated in the opposite direction, and the driven gear (24) is rotated in the other direction by the driving gear (22). At this time, since the locking protrusion 25b is not caught on the moving groove 24a as shown in FIG. 4, the operation lever 25 does not rotate in the locked position, and only the driven gear 24 is After rotation, the motor 23 is stopped, and when the door D is locked, the locking protrusion 25b comes into contact with one end of the moving groove 24a again as shown in FIG. 2.

And in the locked state of the door (D), when the operation using the motor 23 is impossible, such as battery discharge or fire, the indoor user inserts the security key into the key insertion hole 13 When the security key is turned after being inserted into (25a), the other side of the locking projection (25b) is not caught on the moving groove (24a), and the driven gear (24) does not rotate as shown in FIG. Only (25) rotates, and accordingly, the dead bolt 21 moves backward and the door D is unlocked.

When the door (D) is unlocked and then locked using the security key, only the locking protrusion (25b) is moved on the moving groove (24a) and the driven gear (24) does not rotate, and the operation lever (25) ) Only rotates, and thus the driven gear 24, which is bitten by the drive gear 22 during manual operation, does not rotate, so the driven gear 24, the drive gear 22, and the motor connected in a gear engagement structure No load is applied to (23), so no damage or breakdown of parts such as abrasion occurs.

Meanwhile, the indoor unit IB may be provided with a louver in the rim portion 10a so as to prevent a gap between the door D and the indoor unit IB while increasing adhesion when the door D is installed.

However, if the louver is exposed to the outside of the indoor unit (IB), it is not good for the eye and there is a risk of damage to the louver, so the present invention mounts the quadring (R) shown in FIG. 6 to the indoor unit (IB) instead of the general circular cross-section O-ring. Thus, it was possible to more easily mount the quad ring (R) while increasing the adhesion and airtightness.

Specifically, first, the housing 10 of the indoor unit IB is provided with a ring mounting groove G formed in the circumferential direction along the rim portion 10a on the inner surface (rear surface).

And it is fitted into the ring mounting groove (G), including a quad-ring (R) having a lip portion (R1) formed by protruding the corner portion of the square cross-section in an arc shape,

The quad ring (R) includes a fitting hole (R2) formed in the longitudinal direction at the center of the lip portions (R1), and an insertion groove (R3) formed by opening to one side of the fitting hole (R2),

A circular elastic ring part (E1) in close contact with the inner circumferential surface of the fitting hole (R2), a connection part (E2) connected to be inserted into the insertion groove (R3) by crossing an'X' shape at both ends of the elastic ring part (E1) , Including an elastic deformable member (E) consisting of a pressing portion (E4) connected to protrude than the lip portion (R1) at the outer end of the connection portion (E2)

When the indoor unit IB is mounted on the door D, one surface of the door D covering the ring mounting groove G presses the pressing part E4 and the elastic ring part E1 opens, and each lip part ( It is characterized in that R1) is in close contact with the edge of the ring mounting groove (G).

The quadring (R) is a flexible material such as rubber or silicone, and the outer surface of the concave portion between the lip portions (R1) on one side is cut into the insertion groove (R3), so that the lip portion (R1) is centered on the fitting hole (R2). ) Can happen.

In this quad ring (R), a plurality of insertion grooves (R3) are arranged at a predetermined distance along the fitting hole (R2), and the inner diameter of the quad ring (R) is greater than the outer diameter of the ring mounting groove (G). While large, the outer diameter of the quad ring R is formed smaller than the inner diameter of the ring mounting groove (G). That is, the quad ring R has a smaller width than the ring mounting groove G.

The elastic deformable member (E) is mounted by fitting the circular ring-shaped elastic ring portion (E1) corresponding to the quad ring (R) into the fitting hole (R2) in a pipe shape, and at this time, the elastic ring portion (E1) along the The connecting portion E2 and the pressing portion E4 are connected to be arranged at a predetermined interval.

In addition, the connecting part E2 and the pressing part E4 are connected by an extension part E3 formed longer than the distance between the inner circumferential surface of the fitting hole R2 and the outer circumferential surface of the lip part R1, so that the elastic deformable member E When mounted in the fitting hole R2 of the quad ring R, the pressing portion E4 exposed to the insertion groove R3 protrudes more than the outer surface of the lip portion R1.

Therefore, if the housing (10) of the indoor unit (IB) is mounted on one side of the door (D) while the assembly of the quad ring (R) and the elastic deformable member (E) is assembled in the ring mounting groove (G), the ring is mounted. One surface of the door D covering the groove G presses the pressing portion E4 that protrudes more than the one-side lip portions R1.

When the pressing part E4 is pressed in this way, the connection part E2 intersecting in an'X' shape opens the elastic ring part E1, and when the elastic ring part E1 opens and expands in diameter, the quadring R The lip portions E1 of) are in close contact with the corners of the ring mounting groove G, and accordingly, the indoor unit IB is in close contact with the door D by the quad ring R, thereby increasing airtightness.

At this time, compared to the general circular cross-section O-ring, it is difficult to fit the quad ring (R) into the ring mounting groove (G) due to the lip portion (R1), but the quad ring (R) of the present invention is Since it has a width smaller than the width, the quad ring (R) can be easily inserted and mounted,

When the indoor unit (IB) equipped with the quad ring (R) is mounted on one side of the door (D), the width of the quad ring (R) is widened by the elastic deformable member (E), and the lip portion (R1) becomes the ring mounting groove ( It is in close contact with the corner of G) and the door D to provide an effect of improving adhesion and airtightness using the quad ring R.

In the above description of the present invention, the indoor unlocking type digital door lock has been mainly described with reference to the accompanying drawings, but the present invention can be variously modified, changed, and substituted by those skilled in the art, and such modifications, changes and substitutions are the protection of the present invention. It should be construed as falling within the scope.
