Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal structure around a door lock for an automobile door, and more particularly, in a case where an inner panel of a door has a corner portion composed of an end piece and a side piece. Relates to a seal structure around a door lock arranged in.

[0002]

2. Description of the Related Art A sealing structure has been proposed in which a casing of a door lock is made of resin, and a fin piece is integrally provided at a portion of the casing that contacts a door panel (Actually published Japanese Utility Model Publication 56-846).
No. 58). According to this seal structure, the sealing property between the flat door panel and the casing can be enhanced by the fin piece, but when the door lock is arranged in the corner portion, the fin piece does not fit in the corner portion, I can not use it.

By the way, in order to strengthen the resistance against the impact applied to the door of the automobile from the side and suppress the deformation of the door,
An impact beam that extends in the front-rear direction may be attached to the door.However, in such a door, it is necessary to increase the rigidity of the attachment portion between the door lock and the inner panel of the door. Place the reinforcement into.

As shown in FIGS. 5 and 6, an end piece 13a and a side piece 1 of an inner panel 12 of an automobile door 10 are shown.
3b and the door lock 14 is attached to the corner portion and the reinforce 16 is arranged, the reinforce 16 to which the seal material 18 is attached is attached to the end piece 13a of the corner portion and the seal material 18 is attached to the end piece 13a. The door lock 14 is placed so as to face the piece 13a, and the sealing material 20 is attached to the door lock 14 and the side piece 13b of the corner portion. Apply to face the piece 13b. After that, the bolts passed through the bolt holes 22 of the end piece 13a and the bolt holes 24 of the reinforcement 16 are locked in the door lock 14
The door lock 14 is attached to the inner panel 12 of the door.

[0005]

[Problems to be Solved by the Invention] Reinforce 16
Since both the side piece 13b of the inner panel 12 and the side piece 13b of the inner panel 12 are made of metal, a gap is likely to occur, and the sealing material 18 only extends to the outer peripheral edge 17 of the reinforcement 16 as shown in FIG. , A gap 28 is formed between the inner panel 12 and the reinforcement 16 and the sealing material 18, and water easily leaks.

An object of the present invention is to attach a door lock to a corner portion of an inner panel of a door and dispose a reinforce for a door lock in the corner portion, wherein the reinforcement and the inner panel of the door are combined. It is to provide a seal structure around a door lock that prevents water leakage from a gap.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a line-in structure in which an inner panel of a door of an automobile has a first seal member interposed between the end pieces of a corner portion including end pieces and side pieces. A force is applied, and a sealing structure around a door lock is applied in which a second sealing material is interposed between the reinforcement and the side piece of the corner portion. The first sealing material extends over the outer peripheral edge of the reinforcement to the second sealing material, and the outer peripheral edge, the side piece of the corner portion, and the second sealing material. Has an extended portion that contacts with.

[0008]

FUNCTION AND EFFECT The extended portion of the first sealing material contacts the outer peripheral edge of the reinforcement, the side piece of the inner panel and the second sealing material to close the gap.

The extension portion of the first sealing material can close the gap between the reinforcement and the inner panel, thereby preventing water leakage. However, the cost increase for the first sealing material is It is only a few because it only has an extension.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A seal structure 30, as shown in FIGS. 1, 2 and 4, of an inner panel 12 of a vehicle door 10,
The door lock 14 is attached to the corner portion composed of the end piece 13a and the side piece 13b, and the reinforcement 16
In the case of the arrangement described above, the area around the door lock 14 is kept liquid-tight. In addition to bolt holes 22, striker holes 23 are provided in the corners.

The door 10 comprises an inner panel 12 and an outer panel 32, and is equipped with an impact beam 34 attached to the inner side surface of the outer panel 32 and extending in the front-rear direction of the vehicle body. The extension 36 is connected to the impact beam 34 and the inner panel 12, and the reinforcement 16 is connected to the extension 36.

A first seal material 38 is attached to the reinforcement 16. As shown in FIG. 1, the sealing material 38 has a straight portion 39a and an extension portion 39b extending obliquely with respect to the straight portion 39a. In the illustrated embodiment, a stamp sealer formed by punching is used. is there. The spot sealer is adhesive with synthetic rubber as the main component, but it can be punched or extruded.
It adheres to metal as it is. As the spot sealer, for example, Orotex SS-25H (sales destination: Iida Sangyo) can be used.

The straight portion 39a of the first seal member 38 has the same length as that of the conventional one, but the extension portion 39b extends beyond the outer peripheral edge 17 of the reinforcement 16 and extends to the second seal member described later. Extended to 40 and the outer edge 17,
The length of the extension portion 39b and the straight portion 39a are in contact with the side piece 13b of the corner portion and the second sealing material 40.
Determine the tilt angle with respect to.

The second sealing material 40 is attached to the door lock 14. The second sealing material 40 is the door lock 1
The striker hole 15 provided in 4 is surrounded above and on the side. In the embodiment shown in detail in FIG. 3, the sealing material 4
0 is formed by a sponge and has a seal portion 41a that extends downward to the left across the ridgeline with the hole 15 and
And a seal portion 41b extending downward to the right.

The second sealing material 40, as shown in FIG.
Since the seal portion 41a comes into contact with the side piece of the corner portion, the extension portion 39b of the first seal member 38 is
When the door lock 14 is viewed from a direction of about 45 ° as shown in FIG. 3, the extension portion 39b is determined so as to sufficiently overlap with the sealing portion 41a of the second sealing material 40.

To attach the door lock 14, first,
Reinforce 16 with the first sealing material 38 attached
To the end piece 13a of the corner portion and the sealing material 38 to the end piece 1a.
Apply to face 3a. Then, the extension portion 39b of the sealing material 38 is in a state of protruding beyond the outer peripheral edge 17 of the reinforcement 14. Further, the door lock 14 to which the second sealing material 40 is attached is applied to the reinforce 16 and the side piece 13b of the corner so that the sealing material 40 faces the reinforce 16 and the side piece 13b. Guga. As a result, the extended portion 39b of the sealing material 38 contacts the outer peripheral edge 17, the side piece 13b, and the sealing material 40. Then, the bolts passed through the bolt holes 22 of the end piece 13a and the bolt holes 24 of the reinforcement 16 are screwed into the screw holes 26 of the door lock 14,
The door lock 14 is attached to the inner panel 12 of the door.
