The pawl lever 31 is connected to a lock button on the inner side of the door through the lock link 30 so that when the lock button is pushed or when operation is performed from outside the vehicle through a key or other locking device, The link 30 maintains the locked state of the door latch irrespective of the pulling-out of the outward handle or the inner handle.

That is, the lock of the door latch is released through the operation of the out handle and the inner handle only when the lock link 30 is in the release position.

On the other hand, when the vehicle door is unintentionally opened during the traveling, the passenger may suffer a serious injury, so the door should never be opened. However, when the vehicle side collision occurs when the lock link 30 is in the released state during operation, the outer panel 10 of the door is deformed to strike the out lever 20, There is a possibility that the lock of the door latch may be released as the lever 31 rotates in conjunction with it.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a vehicle lock device capable of preventing unintentional opening of a door by switching a lock link to a lock position (locked position) It is a main object to provide a locking structure of a door latch.

In order to achieve the above object, according to the present invention, when the lock of the door latch is released by the rotation of the out lever and the locked state of the door latch is maintained regardless of the rotation of the out lever when the lock link is in the lock position The locking structure of the door latch includes an operation lever whose one end faces the outer panel of the door, and when an impact is applied to the outer panel (due to a side collision of the vehicle body) So that the operation lever slides so that the lock link is moved to the lock position.

The operation lever may further include a lock lever coupled to the spring so as to be held in position by an elastic force, one end rotatably connected to the operation lever, and the other end disposed to face the lock link.

In addition, the operation lever according to the present invention is formed with a bend bent at one end toward the outer panel so that the contact area with the outer panel can be increased.

The present invention as described above has the effect of restricting the door opening due to the side collision, thereby preventing the possibility that the passenger is separated from the vehicle and the secondary gear is caused to occur.

The operation lever is engaged with the spring to suppress unnecessary movement in the door, and the lock lever can be further disposed and spaced apart from the lock link so that the operation lever does not interfere with other components.

In addition, the operating lever may be formed in a shape of a curved one end toward the outer panel of the door to increase the contact area with the outer panel, thereby preventing the operating lever from penetrating through the outer panel upon contact with the outer panel. .

FIG. 1 is a view showing a conventional door latch structure. FIG. 1 is a view showing a state in which a door latch is released by rotation of an out lever by deformation of an outer panel when a side collision occurs,
2 is a view illustrating a door latch structure according to a preferred embodiment of the present invention.
Fig. 3 is a view showing a state in which the lock link is switched to the lock position as the operation lever is slid due to side collision of the vehicle in the door latch structure of Fig. 2; Fig.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings in order that the present invention can be easily carried out by those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
