The present invention relates to an automobile door locking device, and more particularly, a connection lever for setting the central lock state of the locking device is configured to be dualized into a central lock lever and a dead lock lever, and the dualized central lock lever and the dead lock lever are electrically connected. The present invention relates to a vehicle door locking device configured to selectively interlock at the time of lock / unlock switching by a signal and a mechanical operation to implement a deadlock function.

As is well known, a door lock device installed on a door of a vehicle and controlling the safety of the door is generally connected to a latch assembly including a latch, a foul and a foul open lever, and an inside or outside handle lever. A release portion including a release lever for providing an external operating force transmitted by the latch assembly to release the restrained state of the latch assembly, and an external operation force being selectively applied or not applied to the latch assembly through the release lever. It is configured to include the central lock structure to be controlled by. The central lock structure has a structure in which the locked and unlocked state is set by switching the connection lever made by the operation of the central lock motor or the lock knob.

However, in recent years, as more reliable door lock specifications are required, so-called mold door locks having a mold over the entire door lock have been proposed. Such a molded door lock device is not only excellent in corrosion resistance and durability, but also has a full cover structure, so that artificial manipulation of the door lock body through the mouth is difficult, and it is expected to have high security.

However, even if such a molded door latch is implemented, the lock knob connected to the lock lever for switching the connection lever is displayed inside the vehicle, and for the purpose of theft, another person inserts the door into the gap of the window from the outside and then locks the door. By operating the knob, the connection lever can be switched to set the central unlock of the door lock, so the risk of theft remains.

However, removing the lock knob itself, which can be easily set in the car by the central operation, can cause many problems for safety and convenience, which is not a desirable method.

Therefore, the concept of deadlock has been introduced and developed under the circumstances that it is impossible to set up the central lock through the lock lever as needed.

The present invention has been made to solve the problem of the vehicle door locking device provided with only the central lock structure as described above, and provides an automobile door locking device which further improves the anti-theft property of the vehicle by the addition of a structure expressing the deadlock function. It aims to do it.                         

In addition, the operation is smooth and stable, taking a planar action structure can be installed in an integrated form on the upper portion of the latch assembly to provide an automobile door lock device having a deadlock function of the mold door lock device is easy to implement. It is done.

The above object is achieved by the following configuration provided in the present invention.

By the displacement of the lock pin in the slot holes in accordance with the transfer of the deadlock link, the rotation of the deadlock lever through the lock lever is applied or not applied to the central lock lever, thereby enabling the setting of the central unlock state through the lock lever. It is characterized by being configured to be impossible.

On the other hand, according to a preferred embodiment of the present invention, the deadlock driving unit,

Hereinafter, with reference to the accompanying drawings will be described in detail the deadlock-type vehicle door latch according to this embodiment.

1 and 2 are views showing the overall appearance and internal components of the automobile door lock device according to an embodiment of the present invention, Figure 3 is a central lock by expanding the 'A' portion of FIG. It shows the operating status at unlock. 4 and 5 are a perspective view and a plan view showing the deadlock structure and the mechanical backup structure in the vehicle door locking device of FIG. 2, and FIGS. 6A and 6B are 'B' in FIGS. 4 and 5. It is enlarged to show the operation status at the deadlock / unlock setting.

1 to 2, the automobile door locking device 1 according to the present embodiment includes a latch assembly for restraining / releasing a striker installed in a vehicle body; A release part having a release lever 20 for transmitting an external action force to the latch assembly 10 to release the restrained state of the latch assembly; And a central lock structure 30 for setting a selective interlocking / non-interlocking structure between the release lever 20 and the latch assembly 10 by switching the connection lever 31. One side of the lock structure 30 is provided with a deadlock structure 40 for controlling the switching action of the connection lever 31 and a mechanical backup structure 50 for mechanical release of the deadlock state.

First, the configuration and operation of the latch assembly 10, the release portion and the central lock structure 30 of the door lock device 1 according to the present embodiment equipped with a deadlock structure 40 according to the present invention 1 Referring to Figure 3, the latch assembly 10, as in the conventional door lock device for a vehicle, the latch 11 that restrains when a striker (not shown) installed in the vehicle body enters the base plate of the housing The shaft 11a is elastically installed in the pivoting structure, and the pawl 12 is also elastically installed in the pivoting structure in the pivoting structure on the base plate, so as to maintain or release the restraint state of the latch. Will act.

In this configuration, the foul 12 is supported by an elastic means such as a spring (not shown) so that once the latch 11 restrains the striker, it is engaged on one side of the latch to maintain the restrained state.

On the other hand, when the fouling 12 is rotated by an external force, the engagement with the latch 11 is released to release the restrained state of the striker by the latch 11, this release action protrudes on one side of the fouling 12 An operation of an inside handle or an outside handle (not shown) is transmitted to the formed foul open lever 12a through a release unit described later. At this time, the foul open lever 12a may be formed integrally with the body of the foul, or may be disposed on the same axis as the foul to rotate the foul by making a separate lever shape as shown in FIG.

The inside handle lever 21 is coupled to the left end 20a at the release part for rotating the fouling 12, and a binding part for binding the outside handle lever to the right end 20b is formed at the center end. In the 20c, a T-shaped release lever 20 having a long hole 20c-a is elastically axially installed by sharing the fouling shaft 12 and the pivot shaft 12b. The steering wheel is rotated counterclockwise on the drawing. In this case, the foul open lever 12a of the fouling 12 is disposed under the center end 20c of the release lever 20, and the foul open lever 12a is disposed in the long hole 20c-a. The middle part corresponding to the inner side is bent to form a recessed part 12a-a having a predetermined depth, and the distal end corresponding to the right end of the long hole 20c-a protrudes up to the position of the long hole 20c-a so that the locking end ( 12a-b) take the form formed.

 And in the long hole (20c-a) of the release lever 20, one end protrudes downward on the other end of the central lock link 32, which is bounded by a hinge (H) structure on one side of the connection lever (31) The lock pin 32a formed so that it penetrates is inserted.

Accordingly, as shown in (a) of FIG. 3, the release lever 20 is operated counterclockwise by operating the handle in a state where the lock pin 32a inserted in the long hole 20c-a is located on the outer side of the unlocked position. When rotated, the engaging ends 12a-b formed in the foul open lever 12a of the foul are interfered with the lock pin 32a to interlock in the direction of the arrow. On the other hand, even when the release lever 20 rotates counterclockwise by operating the handle in the state where the lock pin 32a inserted in the long hole 20c-a is located on the inner side of the lock position as shown in (b), Since the lock pin 32a moves toward the concave portion 12a-a formed in the foul open lever 12a of the foul and does not interfere with the locking end 12a-b, the foul open lever 12a does not rotate. Therefore, no restraint of the latch 11 is made.

In the door lock device 1 according to the present embodiment, the lock pin 32a of the central lock link 32 is selectively locked or unlocked in the long hole 20c-a in the release portion. The central lock structure 30 which is set to take the lock has a connection lever 31 in which one end of the central lock link 32 is engaged and lock / unlock switching is performed by rotation, and the connection lever 31 is rotated. It comprises a central lock drive 33 and the lock lever 34 to provide a force to carry.

As shown in FIG. 2, the connection lever 31 is coupled to the central lock driving unit 33 and the other end to the lock lever 34 so as to share the latch 11 and the rotation shaft 11a. In addition, one end of the central lock link 32 is bound to the hinge (H) structure on one side, and is rotated by the action force provided from the lock lever 34 or the central lock drive unit 33 to the central lock link. The lock pin 32a of (32) is located in the inner end or the outer end side in the long hole 20c-a of the release lever 20, and it is comprised so that a central lock or unlocked state may be set.

In this embodiment, the connection lever 31 is dualized into a central lock lever 31B and a deadlock lever 31A in order to implement the deadlock structure 40 according to the present invention as described below. This dual structure is not necessary to set up the lock / unlock of the central lock.

Now, the structure of binding to both ends of the connection lever 31 and rotating it will be described. First, the central lock driver 33 includes a central lock motor 33A for generating an electric driving force, and the central lock motor ( The pinion gear 33A-a formed on the output shaft of 33A and the rack gear 33B-a meshing with the pinion gear 33A-a are provided on one surface of the body, and one end of the connection lever 31 is provided. The transfer arm 33B, which has a hinge structure at one end, is pivoted so that the transfer arm 33B is transferred in a straight line by the forward and reverse driving of the central lock motor 33A, thereby turning one end of the connection lever 31. The central lock link 32 having one end connected to the connection lever 31 is set to set the central lock / unlock state.

The central lock driving unit 33 of the rack and pinion structure can not only stably transfer the electric force of the central lock motor 33A to the connection lever 31, but also constitute a planar operation structure. It can be installed in an integrated form at the top of the), it is easy to implement a molded door lock device, and thus it is advantageous to the implementation of the door lock device to improve the anti-theft purpose of the present invention.

On the other hand, the lock lever 34 is coupled to the other end of the connection lever 31 is installed on the shaft 34a in a rotatable structure on the side wall of the door lock device 1, one end 34b is It is attached to the other end of the connection lever 31, and the other end 34c is comprised so that it may be normally bound to manual operation means, such as a lock knob. Therefore, in the locked state, when the user operates the lock knob (not shown) bound to the other end 34c of the lock lever 34, the lock lever 34 is rotated clockwise about the pivot shaft 34a. One end 34b of the lock lever 34 bound to the other end of the connection lever 31 moves to the left side of the drawing to rotate the connection lever 31 counterclockwise to set the central unlock state. On the contrary, when the other end 34c of the lock lever 34 rotates counterclockwise, the connection lever 31 and the central lock link 32 are sequentially linked to set the central lock state.

When the deadlock lever 31A is rotated by operating 34, the first overlapping end 31A-a and the second overlapping hole in which the first slot hole 31A-aa and the second slot hole 31A-aa are formed, respectively. Since the stages 31B-a are rotated counterclockwise by the lock pins 41a together to be in the same state as (B), the central lock lever 31B is also rotated counterclockwise to enter the central unlocked state. Thus, in the state where the lock pin 41a of the deadlock rod 41 is located in the short hole s of the first slot hole 31A-aa formed in the deadlock lever 31A, the lock lever 34 is operated. You can set the central unlock to the dead unlock state.

However, as shown in (a) of FIG. 6B, in the state where the lock pin 41a of the deadlock link 41 is located in the long hole part 1 of the second slot hole 31B-aa, the lock lever 34 Even if the deadlock lever 31A is rotated by manipulating the lock, only the deadlock lever 31A rotates idly so that the lock pin 41a is the other side of the long hole l of the second slot hole 31B-aa as shown in (b). It is located only at the end, and the central lock lever 31B, to which the lock pin 41a and the second overlapping end 31B-a are bound, is not interfering with the deadlock lever 31A and remains fixed. Thus, in this state, the central lock lever 31B is rotated by the operation of the lock lever 34 to become a dead lock state in which the central unlock state cannot be set.

On the other hand, the other end of the deadlock link 41 is delivered to the deadlock driving unit 42, the lock pin (41a) formed at one end of the long hole (l) or short hole of the first slot hole (31A-aa) as described above The deadlock driving unit 42 may include a deadlock motor 42A for forming an electric driving force, pinion gears 42A-a provided on an output shaft of the deadlock motor 42A, and the deadlock driving unit 42.
