The pressing piece 65 is mainly installed in the lock of the driver's seat door to lock the other seat door. It is preferable that the press piece 65 is not provided in an apparatus.

The lock link 62 is provided with an interlocking hole 62b into which the blocking member 69 is inserted, and an elastic member is installed between the interlocking hole 62b and the blocking member 69, and the key locking portion 70 to be described later. Is connected to the connection hole 62a is formed.

When the blocking member 69 and the lock pin 69a are rotated when the second release lever 34 is rotated, the elastic member is compressed to prevent the blocking member 69 and the lock link 62 from interfering with each other.

The door lock device for a vehicle according to the present embodiment further includes a key lock part 70 which transmits a manipulation force of a key inserted into the door to the driven gear part 60.

When the user inserts the key into the door and rotates it, the operating force of the key is transferred to the driven gear part 60 so that the driven gear part 60 is rotated so that the blocking member 69 is set forward or backward and set or release the set roll lock state. do.

The key lock portion 70 is slidably installed on the protrusion 16a formed on the back plate 16 on which the lock link 62 is rotatably installed and connected to the connection hole 62a of the lock link 62. The key link 71 and the key lever 72 rotatably installed on one side of the back plate 16 so as to be rotated by the operation force of the key, and the other side of the back plate 16 connected to the key lever 72. It is rotatably installed on the side and includes a key transfer lever 74 is formed with a driving projection (74a) for moving the key link (71).

When the key lever 72 is rotated by the operation force of the key, the key transfer lever 74 is rotated and the driving protrusion 74a moves the key link 71. Therefore, the operating force of the key is transmitted to the lock link 62, The lock operation or release operation can be performed.

The key link 71 is formed in a long panel shape in the left and right direction, the plurality of operating holes 71a are formed long in the left and right direction, and the protrusions 16a of the back plate 16 are installed to be inserted into the operating hole 71a. .

Therefore, the key link 71 is slidably installed in the left and right directions on the front surface of the back plate 16.

The connecting protrusion 71b formed at one end of the key link 71 is inserted into the connecting hole portion 62a of the lock link 62, so that when the key link 71 slides in the left and right directions, one side of the lock link 62 is opened. Pulling or pushing the linear movement of the key link 71 is converted to the rotational movement of the lock link (62).

The other side of the key link 71 is formed with a driving groove 71c in which the driving protrusion 74a is slidably seated, and the width of the driving groove 71c is sufficiently wider than the thickness of the driving protrusion 74a. .

Therefore, when the operating force of the lock knob is transmitted and the lock link 62 is rotated, the key link 71 connected to the lock link 62 slides in the left and right directions, and the driving protrusion 74a is formed within the driving groove 71c. Since sliding, the key link 71 and the driving protrusion 74a can be prevented from interfering.

When the locking operation or the release operation is performed by the key locking portion 70, the driving link 74a presses the driving groove 71c in a state in which the driving protrusion 74a is in close contact with one side of the driving groove 71c, so that the key link 71 slides. While rotating the lock link 62 to perform the locking operation or release operation.

Since the pressing lever 72a is formed in the key lever 72 to transmit the actuation force of the key to the deadlock unit 90, the key lever 72 rotates while the deadlock unit 90 restrains the driving cam 54. Since the operating force of the key is transmitted to the deadlock portion 90 by the pressing protrusion 72a, the restraint of the driving cam 54 is released.

9 is an exploded perspective view showing the inner release portion 30 of the door lock device for a vehicle according to an embodiment of the present invention.

4 and 9, the internal release part 80 may include a first internal lever 81 rotated by the operating force of the internal handle and a second internal lever transferring the operating force of the internal handle to the release part 30. 82 and a third internal lever 83 for transmitting the operating force of the first internal lever 81 to the second internal lever 82.

When the inner handle is operated by the occupant, the first inner lever 81 is rotated, and the rotational force of the first inner lever 81 is transmitted to the second inner lever 82 by the third inner lever 83, thereby releasing the release portion. 30 is operated to release the restraint of the latch gear 20.

The first inner lever 81 is rotatably installed on the inner rotating shaft 88 installed on the back plate 16 and the pressing groove 81a is formed.

The second inner lever 82 is rotatably installed on the same inner rotation shaft 88 as the first inner lever 81, and a stopper 82a is formed to face the fixed rib 16c of the back plate 16 and protrudes. An 82b is formed and a pressing portion for operating the second release lever 34 is formed.

The third inner lever 83 is rotatably installed on the second inner lever 82 so as to be spaced apart from the inner rotation shaft 88, and a rotation protrusion 83a is formed.

In addition, the first inner elastic member 84 is installed between the back plate 16 and the second inner lever 82 so that the stopper 82a is pressed toward the fixed rib 16c, and the rotary protrusion 83a is provided with the stopper (a). A second internal elastic member 85 is installed between the second internal lever 82 and the third internal lever 83 so as to be pressed toward 82a).

When the operating force of the inner handle is transmitted and the first inner lever 81 is rotated, the rotating protrusion 83a is pressed by the pressing groove 81a, so that the third inner lever 83 is rotated, and the rotating protrusion 83a is a protrusion. Since the second inner lever 82 is rotated by pressing 82b, the pressing portion 82c rotates the second release lever 34 to release the restraint of the latch gear 20.

When the locking operation proceeds, since the rotation protrusion 83a is moved outwardly by the interlocking lock 96, the pressing groove 81a is rotated even when the first inner lever 81 is rotated by the operating force of the inner handle. The rotation force of the first inner lever 81 is not transmitted to the second inner lever 82 because it is not in contact with the protrusion 83a.

Therefore, when the interlocking lock 96 is driven and the door is locked, the door is not opened even when the jig is inserted into the gap between the window and the door plate to operate the inner handle.

The protrusion 82b is formed as a curved surface protruding in the outward direction of the inner rotation shaft 88, and the protrusion 82b does not interfere with the rotation radius of the rotation protrusion 83a and interferes with the rotation radius of the pressing groove 81a.

In the state where the interlocking lock 96 is not driven, the stopper 82a is pushed toward the fixed rib 16c by the first internal elastic member 84 and the rotation protrusion 83a is driven by the second internal elastic member 85. A state in which the pressing groove 81a is inserted into the inside is achieved.

Accordingly, when the first inner lever 81 is rotated, the pressing groove 81a and the rotation protrusion 83a press the protrusion 82b to compress the first inner elastic member 84, thereby compressing the first inner lever 81 and the first. The two inner levers 82 and the third inner lever 83 are rotated at the same time.

When the rotary protrusion 83a is moved outwardly by the interlocking lock 96, the third internal lever 83 is rotated while the second internal elastic member 85 is compressed to rotate the rotary protrusion 83a to the pressing groove 81a. And projections 82b are spaced outward.

At this time, even if the first inner lever 81 is rotated, since the rotational force of the pressing groove 81a is not transmitted to the second inner lever 82, the door is not opened even when the door is locked and the inner handle is operated.

Since the rotation protrusion 83a is disposed to face the interlocking lock 96, when the pressure link 96b (see FIG. 2) of the interlocking lock 96 to be described below presses the rotation protrusion 83a, the second elastic member 67 may be formed. The third inner lever 83 is rotated while being compressed, and the rotation protrusion 83a is spaced outward from the pressing groove 81a and the protrusion 82b.

In addition, since the kids lock protrusion 83b is formed on the third inner lever 83 by the operating force of the kids lock knob, when the kids lock knob is operated, the kids lock lever 86 is rotated and the kids lock protrusion 83b is rotated. By rotating, the third internal lever 83 is rotated.

Therefore, the rotation protrusion 83a is spaced apart from the pressing groove 81a and the protrusion 82b.

8 and 9, the deadlock unit 90 is connected to the locking member 16d of the back plate 16 on which the driving cam 54 is installed and the constraining protrusion 54a. And, the operating unit 91 for supplying the operating force to the connecting member 94, the rack gears geared in a rack and pinion manner to the rotary shaft of the operating unit 91 and the connecting member 94 is rotatably connected (93) ).

When power is applied to the operating unit 91 made of a motor, the rotary shaft of the operating unit 91 is rotated so that the rack gear 93 connected in a rack-and-pinion manner performs a linear movement of raising or lowering.

When the connecting member 94 is inserted between the locking protrusion 16d and the restraining protrusion 54a by the operating force transmitted from the rack gear 93, the rotational motion of the driving cam 54 is constrained, thereby blocking the power of the driving unit 41. Since the member 69 is not transmitted, the operating force of the outer handle is not transmitted to the release part 30.

Since the connecting member 94 is formed with a curved groove portion 94a into which the fixing protrusion 16b of the back plate 16 is slidably inserted, the fixing protrusion 16b is curved when the rack gear 93 is lowered. Sliding along the connecting member 94 performs a pivoting motion.

Accordingly, the connecting member 94 converts the vertical linear motion of the rack gear 93 into the horizontal linear motion of the interlocking lock 96 and transmits the linear motion.

The rack gear 93 and the interlocking lock 96 connected to one end and the other end of the connecting member 94 are rotatably connected to the connecting member 94, respectively, so that the rack gear 93 is connected by the connecting member 94. Interference between the members is prevented when the linear motion of is converted into the linear motion of the interlocking lock 96.

The interlocking lock 96 is rotatably installed on the connecting member 94 and slidably installed on the back plate 16 and rotatably installed on the rotatable link 96a. And a pressing link 96b for moving the lever 83 to the first inner lever 81 outward direction.

When the rack gear 93 descends, the connecting member 94 pivots and presses the coming out link 96a in the direction of the rotation protrusion 83a of the third internal lever 83, and the pressurized link (96a). As the 96b) is moved, the rotation protrusion 83a is pushed outward of the pressing groove 81a of the first inner lever 81.

10 is an exploded perspective view illustrating a sensing unit of a door locking device for a vehicle according to an embodiment of the present invention.

Referring to FIG. 10, the sensing unit 100 includes a switch 102 that transmits a lock state of the latch gear 20 as an electrical signal, and is provided between the latch gear 20 and the switch 102 and the latch gear 20. The control unit 110 for changing the pressing force transmitted to the switch 102 in accordance with the position of the).

When the latch gear 20 is in the locked state and the released state, the pressing force transmitted from the operation unit 110 to the switch 102 changes, so that the switch 102 is operated when the latch gear 20 is locked or released. The control unit can detect the opening or closing of the door.

The operation unit 110 is rotatably installed in the guide rib 112 formed in the latch gear 20 and the housing 14 for accommodating the latch gear 20, and the guide rib 112 is slidably inserted therein. The link unit 120 includes a plurality of pressing surfaces.

When the latch gear 20 is rotated, the position of the guide rib 112 is changed and the link unit 120 is rotated, and the pressing force for pressing the switch 102 is changed by the plurality of pressure surfaces, so the switch 102 is transmitted from the switch 102. The locking or releasing of the latch gear 20 is determined by the electrical signal.

Since the guide rib 112 is formed by connecting a plurality of curved ribs constituting different curvatures in succession, when the latch gear 20 is rotated, the position of the guide rib 112 is changed, and the link portion 120 is guide rib 112. Sliding along, when the sliding portion of the link unit 120 enters another portion of curvature, the amount of rotation is changed and the amount of rotation of the link unit 120 is increased or decreased.

The link unit 120 is formed in a cylindrical shape and rotatably installed in the housing 14, and a first guide protrusion extending from the main body 122 to one side of the guide rib 112. 124, the second guide protrusion 126 extending from the main body 122 to contact the other side of the guide rib 112, the first pressing surface 128 formed on the upper surface of the main body 122, The second pressing surface 129 is formed on the upper surface of the main body 122.

When the latch gear 20 is rotated while the guide rib 112 is inserted between the first guide protrusion 124 and the second guide protrusion 126, the guide rib 112 whose position is variable is the first guide protrusion ( 124 and the second guide protrusion 126 to press the main body 122 is rotated.

At this time, the switch 102, which is in contact with the first pressing surface 128 and maintained in a pressed state, slides along the first pressing surface 128, and the switch 102 moves to face the second pressing surface 129. When the pressing force provided to the switch 102 is variable, the switch 102 is turned on or off.

Since the second pressing surface 129 includes an inclined surface inclined downward from the first pressing surface 128, the switch 102 which is in contact with the first pressing surface 128 faces the second pressing surface 129. When moved, the switch 102 is turned off while releasing the pressing force of the switch 102.

Looking at the operation of the door lock device for a vehicle according to an embodiment of the present invention configured as described above are as follows.

FIG. 11 is a front view illustrating a centrol lock portion and a key lock portion of a door lock device for a vehicle according to an embodiment of the present invention, and FIG. 12 illustrates a centrol lock portion and key lock portion of a door lock device for a vehicle according to an embodiment of the present invention. FIG. 13 is a front view illustrating a deadlock part and an interlocking lock part of a door lock device for a vehicle according to an exemplary embodiment of the present invention.

14 is a state diagram illustrating a deadlock part and an interlocking lock part of a door lock device for a vehicle according to an embodiment of the present invention, and FIG. 15 shows a switch-on state of the door lock device for a vehicle according to an embodiment of the present invention. 16 is a perspective view of FIG. 16 is a perspective view illustrating a switch-off state of a door locking device for a vehicle according to an exemplary embodiment of the present invention.

11 to 16, when the user closes the door, the striker installed in the vehicle body is inserted into the latch gear 20 to rotate the latch gear 20 to close the door.

At this time, since the position of the guide rib 112 is changed when the latch gear 20 is rotated by the striker, the first guide protrusion 124 and the second guide protrusion 126 slide along the guide rib 112 and thus the main body ( 122).

If the latch gear 20 is further rotated after the latch gear 20 is first restrained by the pearl gear 22 (see FIG. 10), the secondary gear is restrained by the pearl gear 22. The rotation amount of the first guide protrusion 124 and the second guide protrusion 126 that has been slid along the 112 passes into a section having different curvatures.

When the rotation of the main body 122 is completed by the operation of the guide rib 112, the first guide protrusion 124, and the second guide protrusion 126 as described above (the switch that was in contact with the first pressing surface 128 ( Since 102 is moved to face the second pressing surface 129, the pressing force used to press the switch 102 is changed to detect the secondary restraint of the latch gear 20.

As described above, since the state of the secondary restraint of the latch gear 20 is determined as the closed state of the door, the malfunction of opening the door while driving the vehicle can be prevented.

When the user locks the door by using the remote control switch while the door is closed, the driving shaft 54 and the main gear 52 are rotated while power is applied to the driving unit 41, so that the driving cam 54, the lock link 62 and As the override lever 64 is rotated, the blocking member 69 is pushed outward of the second release lever 34 (see FIG. 3).

When the blocking member 69 is moved outwardly of the second release lever 34, the lock pin 69a is moved along the sliding groove 34a, so that the lock pin 69a and the step 36a are spaced apart from each other. (See Figure 6)

Therefore, when the first release lever 32 is rotated by manipulating an external handle, only the second release lever 34 is rotated, and the pearl gear lever 36 is not rotated, thereby preventing the door from being opened. Reference)

After the centrol lock state is made, power is applied to the operation unit 91 so that the rack gear 93 descends, and the connecting member 94 connected to the rack gear 93 is a fixing protrusion 16b (see FIG. 8). Sliding while sliding along the insertion is inserted into the space between the restraining projection (54a) and the locking projection (16d).

When the operating force of the lock knob is transmitted to the override lever 64, the first elastic member 66 (see FIG. 7) is compressed, and only the override lever 64 is rotated, and the lock link 62 is not rotated.

Therefore, a deadlock state is achieved in which the operating force of the lock knob is not transmitted to the blocking member 69.

When the deadlock state is made, the releasing link 96a and the pressure link 96b rotatably connected to the connecting member 94 are linearly moved in the direction of the rotation protrusion 83a, so that the rotation protrusion 83a is pressed against the pressing groove ( 81a) pushed outward.

When the rotation protrusion 83a and the pressing groove 81a are spaced apart, when the operating force of the inner handle is transmitted to the first inner lever 81, only the first inner lever 81 is rotated, and the rotational force of the first inner lever 81 is rotated. Since the second inner lever 82 is not transmitted, the operating force of the inner handle is not transmitted to the release unit 30.

When the user operates the kids lock switch, the kids lock lever 86 (FIG. 2) is rotated to rotate the kids lock protrusion 83b of the third inner lever 83, so that the rotation protrusion 83a is the pressing groove 81a. It moves to the outside to block the operating force of the inner handle.

As a result, it is possible to provide a door lock device for a vehicle in which the door cannot be opened by operating the lock knob or the inner handle while the door is locked.
