Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in the structure for fixing a striker to the body side for engaging with a door lock mechanism of an automobile to lock the door.

In a conventional automobile door lock striker fixing structure, for example, a luggage door lock striker 1 shown in FIG. 1 is attached to a body side panel 5 by a base plate 2 of the striker 1 with a bolt 3 and a nut 4 screwed thereto.

When this striker 1 is attached to the body side panel 5, it is necessary to align the positional relationship between the striker 1 and the lock mechanism on the door side, so the through hole for the bolt 3 of the body side panel 5 is formed large. As a result, the striker 1, which is fastened and fixed to the body side panel 5, can be applied with an impact force using a hammer or the like to adjust the mounting position.

However, such adjustment of the striker 1 has the problem that if the shaft diameter of the bolt 3 of a luggage door or the like is small and the body side panel 5 is also weak, the bolt 3 or the body side panel 5 may be deformed. be.

Also, as shown in Figure 2, the center pillar 6
When installing the striker 1 on the
There is one in which the bolt 3 is integrally welded to the center pillar 6 and the bolt 3 is screwed into the nut 4 which is integral with the nut plate 7.

In this case, with the base plate 2 of the striker 1 tightened by the bolt 3 and nut 4, an impact force is applied to the striker 1 so that the bolt 3 moves slightly within the through hole formed in the center pillar 6. Therefore, the nut plate 7 is used to adjust the position of the striker 1.
In order to prevent the plate from being deformed by the tightening force when tightening the bolts, it is necessary to increase the thickness of the plate, which poses a problem in that a corresponding impact force is required when adjusting the striker 1.

On the other hand, the welding point of the nut plate 7 to the body side is set at a position away from the nut 4, thereby making it easier for the nut 4 side to displace the nut plate 7 around the welding point, and the striker 1
A configuration has been proposed in which the mounting position of the striker 1 can be easily adjusted even if the striking force is small.

However, in this way, nut plate 7
If the nut 4 side of the nut 4 is easily displaced, the assembly force when screwing the bolt 3 into the nut 4 integrated with the nut plate 7 will cause the nut 4 of the nut plate 7 to displace easily.
There is a problem in that the sides are easily displaced or deformed, making it difficult to thread the bolt 3 into the nut 4.

Specifically, when the bolt 3 is pushed into the nut 4, the nut 4 is pushed into the nut plate 7.
It escapes backwards around the welding point, making assembly difficult.

This idea was made in view of the above problems, and is designed to prevent the nut side of the nut plate from escaping during assembly work, and to make the nut plate 7 thinner without reducing its strength. The object of the present invention is to provide a striker fixing structure for an automobile door lock.

This device is arranged on the back side of the mounting surface of the striker to the body of the vehicle to engage with the door lock mechanism of the automobile to lock the door, and is welded to the body side at a position away from the through hole formed in the mounting surface. a nut plate, a nut welded to the nut plate at a position substantially aligned with the through hole, a bolt inserted from the front side of the body into the through hole of the mounting surface and screwed into the nut, and the nut plate. a back panel disposed at a position on the back side of the lock and separated therefrom, and the striker, body, and nut plate are tightened by the bolt and nut to fix the striker. In the striker fixing structure, the nut plate stands near the nut in the thickness direction of the nut plate;
The above object is achieved by forming a flange whose tip reaches near the back panel.

Embodiments of the present invention will be described below with reference to the drawings.

In this embodiment, the same or corresponding parts as those of the conventional door lock striker fixing structure shown in FIGS. 1 and 2 will be designated by the same reference numerals, and a description thereof will be omitted.

As shown in FIGS. 3 and 4, this embodiment is a mounting surface of a striker 1 on a body side panel 5 for engaging with a door lock mechanism of an automobile to lock a door (none of which is shown). A nut plate 17 arranged on the back side of the mounting surface 5A and welded to the body side panel 5 at a welding point 11 remote from the through hole 8 formed in the mounting surface 5A;
A nut 4 is welded to 7 at a position substantially aligned with the through hole 8, and a bolt 3 is inserted into the through hole 8 of the mounting surface 5A from the front side of the body side panel 5 and is screwed into the nut 4. In the striker fixing structure for an automobile door lock, the striker 1 is fixed by tightening the striker 1, the body side panel 5, and the nut plate 17 with the bolt 3 and the nut 4. A flange 9 that stands up in the thickness direction of the nut plate 17 is formed near the nut 4 on the nut plate 17.

As shown in FIG. 4, the nut plate 17 extends left and right around the striker 1 so as to be aligned with the bolt through hole 2A formed in the base plate 2 of the striker 1 and the through hole 8 of the body side panel 5. A pair of flanges 9 are provided, and the upright height of the flanges 9 is slightly smaller than the distance from the back side of the mounting surface 5A to the back panel 10 behind it.

Further, in the nut plate 17, the periphery of the flange 9 and the nut 4 and the welding point 11 to the back surface of the body side panel 5 are connected by an elongated and curved weakened part 12. ,
The welding point 11 is around the nut 4 and flange 9.
It is designed so that it can be easily displaced.

In this embodiment, even if the force of pushing the nut 4 inward by the bolt 3 when tightening the striker 1 to the body side panel 5 is strong, the flange 9 of the nut plate 17 remains in the back panel 10.
Since the nut 4 is raised until it approaches the bolt 3, the nut 4 is prevented from escaping backwards from the bolt 3.
Therefore, the work of tightening the striker 1 becomes easier.

In addition, when adjusting the position of the striker 1 with respect to the door locking mechanism after tightening and fixing, since the welding point 11 and the nut 4 are connected by the fragile part 12, the striker 1 is not affected by a small impact force. Therefore, the position of the striker 1 can be adjusted very easily.

Further, in this embodiment, the nut plate 1
Since the flange 9 is formed to stand up at right angles to the main body of the nut plate 17, the rigidity of the nut plate 17 is greatly increased.
Even if it is made of a thin plate, it will not be easily deformed by the tightening force of the bolt 3.

Note that the above embodiment concerns the striker position with respect to the lock mechanism of the luggage door, but
The present invention can naturally be applied to a striker in a side door locking mechanism.

Further, in the above embodiment, the nut plate 17 has only one welding point 11, whereas the nut 4 has only one welding point 11.
are connected via two weak parts 12,
This is not limited to the configuration of the embodiment, as long as the nut 4 can be easily displaced with respect to the welding point 11.

Therefore, for example, the structure may be such that there are two welding points and one or three or more weak parts.

Since the present invention is constructed as described above, the nuts of the nut plate are prevented from escaping backwards when tightening the bolt, and the rigidity of the nut plate itself can be greatly increased. It has an excellent effect of being able to reduce the size and weight.
