Abstract

(57) [Summary] (with modifications) [Purpose] To prevent contact noise between reinforcement members and reinforcements. [Structure] A reinforcing member 5 is arranged in the front-rear direction between the door outer panel 2 and the door inner panel 3, and a reinforcement 9 is arranged in the direction intersecting this reinforcing member, and facing the reinforcing member. A hole 10 is bored in the plate surface of the reinforcement, and a part of the filler 11 filled at a predetermined interval between the reinforcement and the door outer panel is extruded through the hole to the reinforcing member side. The reason lies in the fact that a filler material is interposed between the reinforcements.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a reinforcing structure for automobile doors.

0002

[Conventional technology]

In order to improve the side strength of automobile doors, reinforcing materials are placed inside them. There is something. As a reinforcing structure, as shown in Figures 9 and 10, the door panel Between the outer panel 101 and the inner panel 102 that make up the Reinforcement structure in which Reinforcement 103 is inserted for reinforcement -116215) and vertical lean as shown in Figures 11 and 12. A lateral reinforcement 104 is inserted in place of the forcement 103 to compensate. A reinforced structure (Japanese Unexamined Patent Publication No. 62-255221) is known. .

0003 However, if the reinforcement 103 is inserted vertically, the outer panel Although the strength of the belt line portion 105 of the belt line 101 is improved, the strength in the horizontal direction is insufficient. becomes. Also, the upper end flange 101a of the outer panel 101 is attached to a door facing downward. In this case, the welding of the reinforcement 103 is not spot welding but arc welding. Since it is welded, there are many problems in terms of quality, workability, and appearance. On the other hand, the horizontal reinforcement Inserting the seat 104 improves the strength in the horizontal direction, but the belt line portion 1 The strength of 05 is insufficient.

0004 Also, both reinforcement 103 and reinforcement 104 are used. Sometimes used.

[0005]

[Problem that the idea aims to solve]

However, reinforcement 103 and reinforcement 104 When used, interference occurs between the two parts, causing contact noise, a so-called chattering sound. this To prevent chattering noise, reinforcements 103 and 104 should be fixed together by welding, etc. However, there is a problem that the number of man-hours increases and the cost increases.

[0006] The present invention solves the above problems and improves the rigidity of the door outer panel. A reinforcement structure for automobile doors that can eliminate chattering noise between reinforcements The purpose is to provide.

[0007]

[Means to solve the problem]

In order to solve the above problems, the present invention has been developed to A reinforcing member is placed in the front-rear direction, and a lean leaf is placed in the direction that intersects this reinforcing member. In the reinforcement structure of an automobile door equipped with a forcement, the above-mentioned reinforcement member is A hole is drilled in the facing plate surface of the reinforcement, and the reinforcement and driver are connected. A part of the filler to be filled between the outer panel and the outer panel is inserted through the hole mentioned above. A filler material is inserted between the reinforcing member and the reinforcement by extruding it to the strong member side. There is a reason for this.

[0008]

【Example】

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

[0009] 1 to 3, a door panel 1 has a door outer panel 2 and a door inner panel. between the door outer panel 2 and the door inner panel 3. The door glass 4 is raised and lowered.

0010 A pipe-shaped reinforcing member 5 is provided between the door outer panel 2 and the door inner panel 3. are arranged in the front-rear direction, and this reinforcing member 5 has both sides as shown in FIGS. 4(a) and (b). The ends are supported on both sides of the door panel 1 via brackets 6 and 7.

[0011] In the middle of the reinforcement member 5, there is a reinforcement member that reinforces the belt line portion 8. 9 are arranged in the vertical direction. This reinforcement 9 is shown in Figure 5. In addition, a hole 10 is bored at a position facing the reinforcing member 5.

0012 A foamed silicone is used as a filler between the reinforcement 9 and the door outer panel 2. The rollers 11 are filled at predetermined intervals. A portion 11a of this foamed sealer 11 is It is filled between the reinforcement member 5 and the reinforcement member 5 through the hole 10 of the reinforcement 9.

[0013] Next, the reinforcing member 5 and the reinforcement 9 are assembled in FIGS. 6 to 8. Explain according to the following.

[0014] Apply foam sealer 11 to the reinforcement 9 and apply it to the door outer panel 2. Press down (see Figure 6). In this way, the foamed sealer 11 is applied to the reinforcement 9. A portion is pushed out from the hole 10 (see FIG. 7). Next, reinforcing member 5 is It is pressed against the forcement 9 and adhered via the foam sealer 11 (see FIG. 8).

[0015]

[Effect of the idea]

As described above, according to the reinforcing structure for automobile doors according to the present invention, the reinforcing member A hole is drilled in the plate surface of the reinforcement member facing the reinforcement member. Pass some of the filler material that will be filled between the door and the door outer panel at specified intervals through the hole. and extrude it to the reinforcing member side to insert a filler material between the reinforcing member and the reinforcement. By applying the filler, the reinforcing members and reinforcement It is possible to eliminate the contact noise between the two.
