Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a vehicle door lock device.

(Prior Art) It is well known that a vehicle door lock device generally has a function of securing a door in a closed state by engagement of a latch and a striker. In addition to the above, for example, there is one having ancillary functions such as self-lock, self-cancel, and keyless lock, and further having an override function.

What does this override function look like?
When the door lock knob provided on the indoor side is pushed down to the locked state, the inside handle is manipulated by mischief, or even if the outside handle is operated from outside, the door lock knob is swung freely and the door lock knob is pulled up directly.
It has a mechanism that cannot be unlocked except to unlock it by operating the key from the outside, but by operating the inside handle only in the front door of the driver side even if the door lock knob is pushed down. It can be unlocked.

More specifically, in the functional parts of the door lock device, the door lock knob is connected to the knob lever, the outside handle is connected to the sub lever, and the inside handle is connected to the inside lever. Further, when the latch is in a latched state in which it meshes with the striker, the latch is engaged and restrained by the open lever, and the latch can be switched to the unlatched state by rotating the open lever to release the restraint.
The sub-lever is linked to the cancel lever and the knob lever, and the cancel lever is linked to the inside lever via the open lever.

Therefore, when the door lock knob is pushed down, the sub-lever that rotates the open lever enters a locked state in which the knob lever switches the open lever operating position to the idling position.
That is, when the inside lever is fully operated to the full operation position, the inside lever is rotated by the inside lever, the latch is in the unlatched state, and the door can be opened. At the same time, the cancel lever is actuated by the rotation of the open lever, and by this actuation of the cancel lever, the sub-lever at the idling position is pushed to the open lever actuating position and returned.

(Problems to be solved by the invention) As described above, the override mechanism is a mechanism for pushing the inside lever → open lever → cancel lever → sub-lever in the order of operating the inside handle to the full operating position to release the latch. Therefore, the operation is completed only after the full operating position, that is, the inside handle is fully operated until it hits, so the impact at the time of contact when the handle is operated is transmitted to the hand, and the operation feeling is very bad.

Generally, the inside handle such as the outside handle is unlatched immediately before the operation is completed, and no impact occurs, and the operation feeling leaves a play allowance in the handle operation, so the inside handle collides. There is a problem that the operation feeling is uncomfortable in the override operation in which the operation is fully performed, and a unified operation feeling cannot be obtained.

Therefore, an object of the present invention is to provide a door lock device for an automobile, which can provide an operation feeling that is comfortable even when an overriding operation is performed.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, in the present invention, a latch that is rotatable between a latched state in which a striker is engaged and an unlatched latched state is provided. , An open lever that engages with a latch in a latched state in a disengageable manner, a knob lever that is rotatable between a locked position and an unlocked position, and an interlocking linkage with the knob lever that operates the open lever to engage with the latch. A sub-lever that is rotatable between an open lever operating position and a swinging position to release the engagement, a cancel lever that is rotatable to a standby position and a pressing position that abuts the sub-lever in the swinging position and presses the open lever operating position, It has an inside lever which is interlockingly linked with an open lever and is rotatable from a non-operating position to an operating position, and when the sub-lever is in an idle position, By rotating the inside lever from the neutral position to the full operating position, the open lever, the cancel lever, and the sub-lever are contacted in this order to put the latch in the unlatched state, and the sub-lever at the idle position is returned to the operating position. In a vehicle door lock device, a stopper on the side of the sub-lever and a stopper on which an abutment part of a cancel lever is pressed from an idle position to an open lever operating position when the inside lever is in the process of moving from a neutral position to a full operating position. And a stopper portion on the sub-lever side outside the contact portion area on the cancel lever side at a position immediately before the completion of operation of the inside lever while engaging with the locking portion on the sub-lever side on the inside lever. Provide a locking part to move to and make a play with the abutting part It is.

(Operation) According to such an automobile door lock device, when the inside lever is rotated in the locked state where the latch engages with the open lever and the sub-lever is in the idling position, the inside lever is in operation. At times, the open lever disengages from the latch and an unlatched condition is obtained. At this time, the sub-lever is pressed from the idling position to the open lever operating position by the contact portion of the cancel lever that contacts the stopper portion. At the position immediately before the completion of the operation of the inside handle, the stopper portion of the sub-lever moves to the outside of the contact area of the cancel lever by the locking portion, and play is created between the contact portion and the operation, leaving a play allowance. Feeling comes to be acquired.

(Embodiment) An embodiment of the present invention will be described below in detail with reference to the drawings of FIGS. 1 to 9.

In FIG. 6, reference numeral 1 denotes a latch capable of engaging with the striker 3 when the door is fully closed. The latch 1 is attached to the base plate 5 and is always in a standby position facing the striker entry path 7 as shown by the chain line in the figure.
When it enters, the latch shaft rotates around the latch shaft 1a to the meshing position and engages with the engaging portion 11 of the open lever 9 to be in a latched state (solid line in the figure).

The open lever 9 is provided with the aforementioned engaging portion 11 via the lever shaft 9a and is constantly urged to the latch restrained position (solid line in FIG. 6) by the urging spring (not shown).
The locking portion 11 is rotated by 13 or the inside lever 15 (arrow B in FIG. 6) so that the engagement with the latch 1 is released. As a result, the latch 1 can be switched from the latched state to the unlatched state (chain line in FIG. 6).

The inside lever 15 is rotatably supported by a lever shaft 15a as a fulcrum, and one end is an inside handle inside the door.
The inside handle 17 is interlocked and linked via a linking mechanism 19, and can be rotated from the non-operating position a to the operating position a ₁ by operating the inside handle 17. Inside lever 15 lever
Reference numeral 21 denotes a first contact portion 25 of a cancel lever 23, which will be described later, and a locking portion 27 which is opposed to the first contact portion 25 with the open lever 9 interposed therebetween and has an angled cross section.

The sub-lever 13 has a protruding stopper portion 29, and an elongated hole 35 slidably fitted with the engaging pin 33 of the knob lever 31.
And an engaging portion 37 that engages with the engaging portion 27 on the inside lever 15 side in a disengageable manner, and the upper end portion is interlockingly connected with the outside handle 39 on the outside of the door through a connecting mechanism 41. ing. As a result, the sub-lever 13 moves vertically (in the direction of arrow B in FIG. 3) within the elongated hole 35 by operating the outside handle 39, and as shown in FIG. When operating the direction,
By the movement (solid line and chain line) of the knob lever 31 interlockingly linked with the engaging pin 31, it is possible to rotate between the open lever operating position b and the idling position b1 with the connecting portion 13a as a fulcrum.

The locking portion 37 of the sub-lever 13 is formed in an angled cross-section, faces the locking portion 27 of the inside lever 15, and has an upper surface serving as an operating surface 37a for pressing the open lever 9. When it is in the operating position b, it faces the operating locus W line of the open lever 9, and as shown in FIG. 2, it is set so as to be out of the operating locus W in the idling position b ₁ .

The elongated hole 35 of the sub-lever 13 allows the sub-lever 13 to move up and down when the outside handle 39 is operated, but at this time, the operating surface 37a of the locking portion 37 is opened without affecting the knob lever 31. It has a vertically long shape that allows the lever 9 to move in the vertical direction along the operation restriction W of the lever 9.

The knob lever 31 is rotatable between a lock position C and an unlock position C ₁ with a lever shaft 31a as a fulcrum, and one end of the knob lever 31 is interlocked with a door lock knob 43 inside the door through an interlocking mechanism 45, and When the lock knob 43 is pushed down, it becomes the lock position C, and when the door lock knob 43 is pulled up, it is switched to the lock release position C ₁ .

The relationship between the knob lever 31 and the sub-lever 13 that is interlockingly linked via the engagement pin 33 is that when the knob lever 31 is in the unlocked position C ₁ , the sub-lever 13 is in the open lever operating position b and the knob lever 31 is When in the lock position C, the sub-lever 13 is set to the idling position b ₁ .

On the other hand, the cancel lever 23 has the above-mentioned first contact portion 25.
Of a second contact portion 47 to the outside, and can rotate in a pressing position d and the standby position d ₁ of the lever shaft 47a as a fulcrum.
As described above, the first contact portion 25 faces the lever portion 21 of the inside lever 15 with the open lever 9 interposed therebetween, but the second contact portion 47 is the stopper portion of the sub-lever 13. It faces 29.

Next, the operation will be described. When the door is open, as shown in Fig. 1, the sub-lever 13 is the open lever operating position b, the inside lever 15 is the non-operating position a, the knob lever.
31 is the unlocked position C ₁ and the cancel lever 23 is the standby position
at d ₁ . When the door is fully closed in this state, the latch 1 engages with the engaging portion 11 of the open lever 9 through the half latch that meshes with the striker 3 and becomes the latched state (full latch) as shown by the solid line in FIG. In this latched state, when the door lock knob 43 is pushed down, the knob lever 31 becomes the lock position C as shown in FIG. At the same time, the sub-lever switches to the idling position b ₁ . Therefore, even if the outside handle 39 is operated, the operating surface 37a of the sub-lever 13 is swung with respect to the open lever 9 and is not released. In this case, pull up the door lock knob 43 or operate the key from the outside to move the knob lever 31 to the unlocked position.
By setting to C ₁ , the latch release state by the outside handle 39 can be obtained.

Further, in the state (FIG. 2), when the inside handle 17 is operated, the lever portion 21 of the inside lever 15 rotates clockwise about the lever shaft 15a as a fulcrum, and the locking portion 27
Engage with the locking portion 37 of the sub-lever 13. When the rotation further continues, the lever portion 21 presses the open lever 9 and the first contact portion 25 of the cancel lever 23, and the cancel lever 23 rotates clockwise. As a result, the latch 1 is in the unlatched state (chain line in FIG. 6), the second contact portion 47 of the cancel lever 13 hits the stopper portion 29, and the sub-lever 13 pushes from the idle position b ₁ to the open lever operating position b. To be done. At the same time, the sub-lever 13 is a locking part.
When the inside lever 15 is moved upward by 37 and 27, the stopper portion 29 is disengaged from the area of the second contact portion 47 at the position immediately before the completion of the full operation of the inside lever 15 (I in FIG. 4), and the stopper portion 29 is moved to the second
A play α is created between the contact portion 47 and the contact portion 47.

Therefore, the inside handle 15 is in the full operating position a ₁
You will be able to perform an override operation that leaves a play allowance.

When the sub lever 13 is in the idling position b ₁ and the knob lever 31 is in the lock position C as shown by the chain line in FIG. 5, when the door is fully closed, the open lever 9 and the cancel lever 23 are moved by the movement of the latch 1 that meshes with the striker 3. By rotating the cancel lever 23 (arrow C), the sub-lever 13 is returned to the open lever operating position b, and the knob lever 31 is returned to the unlocked state C ₁ in a self-cancelled state.

[Effect of the Invention] As described above, according to the vehicle door lock device of the present invention, a play is created between the contact portion of the cancel lever and the position immediately before the completion of the full operation of the inside lever during the override operation. As a result, it is possible to obtain a comfortable operation feeling.
