Description

Description: TECHNICAL FIELD The present invention relates to a trunk lid lock device for an automobile.

(Prior Art) A locking device for a trunk lid of an automobile generally includes a striker provided on a vehicle body side, a latch and a claw lever provided on a lid side, and a cylinder lock.

The latch is rotatably pivotally attached to a base fixed to the lid, and engages with the striker. The claw lever is pivotally attached to the base so as to be rotatable, and engages with the latch to maintain the engagement between the latch and the striker. When the claw lever is rotated by the key operation of the cylinder lock or the lever operation from the driver's seat to disengage the latch, the engagement between the latch and the striker is released and the lid is opened. .

(Problems to be Solved by the Invention) However, in the conventional device, the end faces of the latch and the claw lever come into contact with each other and engage with each other, so that an abnormal impact, for example, a rear-end collision or a collision, has a large effect on the opening direction of the lid. In this case, the latch may be displaced in the plate thickness direction, disengagement from the claw lever, the lock may be released, and the lid may be opened.

Then, after attaching a latch and a claw lever to a base, there is a thing which put a cover plate on these so that a latch and a claw lever might not mutually shift in a board thickness direction, but in this case, a cover plate was added. There is a problem that the weight is increased by that much and the mounting work is complicated.

The present invention has been made in view of the above problems, and has a simple structure that does not involve an increase in weight or complexity of installation, and that can prevent the latch from being disengaged from a claw lever. The purpose is to provide.

(Means for Solving the Problems) In order to achieve the above object, the present invention is configured such that a latch is rotatably pivoted on a base surface, and a latch is engaged with a striker; In a trunk lid lock device including a claw lever that engages with the latch to maintain the engagement between the latch and the striker, a protruding portion that protrudes on the upper surface of the latch near an engagement portion between the latch and the claw lever is provided on the craw lever. It is provided.

(Operation) According to the configuration, in the engaging portion between the latch and the claw lever, the displacement of the latch in the plate thickness direction is prevented by the projecting portion and the base.

Next, an embodiment of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, a U-shaped striker 1 is fixed in a gate shape to an edge 2 on the vehicle body side of a trunk room of an automobile, and is attached to the inside of the trunk lid 3 when the trunk lid 3 (see FIG. 2) is closed. The cutout 5 of the base 4 is fitted.

The latch 6 is pivotally connected to the base 4 by a support shaft 7 so as to be rotatable, and engages with a meshing portion 8 intersecting the cutout 5 of the base 4 and an engaging claw 15 of a claw lever 13 described later. Recess 9
And a bent portion 11 to which one end of the spring 10 is hooked. When the latch 6 rotates clockwise in FIG. 1 and meshes with the striker 1, the meshing portion 8 closes the cutout 5 of the base 4, and when the latch 6 rotates counterclockwise, one end surface thereof The notch 5 of the base 4 is opened by contacting and locking the edge bent portion 12 of the base 4.

The claw lever 13 is pivotally attached to the base 4 by a support shaft 14 so as to be freely rotatable, and engages with an engagement claw portion which engages with the engagement recess 9 of the latch 6.
15 and a bent portion 16 near the engaging claw portion 15 at which the other end of the spring 10 is hooked. The bent portion 16 has a projection 17 formed on the surface of the latch 6 when the engagement claw 15 is engaged with the engagement recess 9 of the latch 6. The overhang portion 17 comes into contact with a substantially intermediate portion of the spring 10 hooked on the bent portion 16. One end of the claw lever 13 is connected to a cylinder lock (not shown) by a rod 18, and the other end is connected to an open lever in a driver's seat by a wire (not shown).

The latch 6 and the claw lever 13 are urged by a spring 10 to attract each other. That is,
The latch 6 is biased counterclockwise about the support shaft 7 in FIG. 1, and the claw lever 13 is biased clockwise about the support shaft 14 in FIG.

In the cylinder lock having the above configuration, in the locked state, as shown in FIG. 1, the engagement concave portion 9 of the latch 6 engages with the engagement claw portion 15 of the claw lever 13, and the striker 1 engages with the engagement portion of the latch 6. 8 and is confined in the cutout 5 of the base 4. Also, the projecting portion 17 of the craw lever 13 is
As shown in the drawing, since the latch 6 projects over the surface of the latch 6 and is close to the latch 6, even if the latch 6 is displaced in the plate thickness direction, the latch 6 is blocked by the projecting portion 17 and the base 4 so that the engagement claw 15 And the engagement recess 9 is not disengaged.

In this locked state, when the cylinder lock is unlocked by a key operation, the rod 18 is pushed in the direction of arrow A, and the claw lever 13 rotates counterclockwise around the support shaft 14 and the engagement claw portion 15 is The latch 6 is released from the engagement recess 9. The same is true when the driver pulls in the direction of arrow B by operating the lever from the driver's seat. This causes the latch 6 to rotate counterclockwise by the urging force of the spring 10, as shown in FIG.
The notch 5 of the base 4 is opened, the striker 1 is detached from the notch 5 and becomes an unlocked state, and the lid 3 can be opened. At this time, one end of the latch 6 is connected to the base 4
The spring 10 vibrates due to the impact, but the projection 17 of the claw lever 13
, Vibration is reduced and generation of abnormal noise is prevented.

Subsequently, when the lid 3 is pushed down from the state shown in FIG. 2, the striker 1 comes into contact with the meshing portion 8 of the latch 6, and the latch 6 is pushed by the striker 1 and the second striker is pressed against the biasing force of the spring 10. The lever rotates clockwise in the figure, and the engaging claw 15 of the claw lever 13 is fitted into and engaged with the engaging recess 9 of the latch 6. At the same time, the meshing portion 8 of the latch 6 meshes with the striker 1 to close the cutout 5 of the base 4, and the locked state shown in FIG. 1 is established. Although the spring 10 vibrates due to the impact at this time, the vibration is alleviated by the contact of the overhanging portion 17 as described above, so that no abnormal noise is generated.

(Effects of the Invention) As is apparent from the above description, according to the present invention, the engagement between the latch and the claw lever is prevented from being disengaged by a simple structure in which the claw lever is provided with a protruding portion projecting from the upper surface of the latch. This has the effect of preventing an increase in weight and the complexity of assembly work.
