DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower door molding mounting structure provided at the lower end of a door of an automobile or the like for sealing between the lower end of the door and a rocker.

[0002]

2. Description of the Related Art Conventionally, at the lower end of a door of an automobile or the like, when the door is opened and closed, the lower end of the door interferes with the curb to prevent the hemming portion from being damaged, and muddy water and the like jumped up during traveling run. A molding under the door is attached so that it does not stick to the lower part of the door opening of the vehicle body.
No. 28625.

[0003] As shown in FIG. 3, in this door lower molding mounting structure, the door lower molding 70 is connected to a lower end 72 of a door 72.
A, and an extending portion 70B extending downward from the attaching portion 70A. The extending portion 70B has a vehicle width of the rocker panel 74 facing the lower end portion 72A of the door 72. It overlaps outward in the direction to protect the lower end of the door at the time of curb interference, and prevents muddy water and the like jumped up during traveling from sticking to the lower part 80 of the door opening of the vehicle body.

[0004] In this door lower molding mounting structure, a base 70C extends from the extension 70B of the door lower molding 70 to cover the mounting portion 70A upward of the door.
With the shaft 76 provided at the lower end of the base 70C as the center of rotation, the extension 70B and the base 70C are integrally formed as shown in FIG.
In the clockwise direction (direction of arrow M in FIG. 3) and the counterclockwise direction (direction of arrow N in FIG. 3). For this reason, when the door 72 is opened, even if the extension 70B of the lower molding 70 interferes with the curb 82 or the like, the extension 70B and the base 70C swing in the direction of the arrow M, and FIG. 3 from the position of the imaginary line of FIG. 3 to the position of the solid line in FIG.

[0005]

However, in this door lower molding mounting structure, the mounting portion 7 of the door lower molding 70 is not provided.
0A is fixed to the lower end 72A of the door 72 by a screw 80. Therefore, in this door lower molding mounting structure,
Since it is necessary to secure a sufficient space for attaching the screw 80 to the mounting portion 70A of the door lower molding 70, it is difficult to reduce the size of the door lower molding 70, and at the time of assembly, the screw 80
The mounting work is not good because the tightening work is required.

The present invention has been made in consideration of the above-described circumstances, and has as its object to provide a molding structure under a door that can be reduced in size and has good assembling workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the under door molding mounting structure of the present invention will be described with reference to FIGS.

In the drawings, an arrow FR indicates a forward direction of the vehicle body, an arrow IN indicates an inward direction of the vehicle width, and an arrow UP indicates an upward direction of the vehicle body.

As shown in FIG. 2, a side door 1 of a vehicle body is provided.
Reference numeral 0 includes a door outer panel 12 that forms the vehicle width direction outside portion of the side door 10 and a door inner panel 14 that forms the vehicle width direction inside portion of the side door 10.

As shown in FIG. 1, a door outer panel 1 is provided.
2 and lower end 1 of door inner panel 14
4A is connected to each other by hemming, and the connecting portion is a hemming portion 16 extending along the lower end of the side door 10 in the front-rear direction of the door. A hemming sealer 18 for preventing corrosion is applied to a portion of the door outer panel 12 that covers the folded end 12B of the lower end 12A.

In a portion of the door inner panel 14 near the upper side of the hemming portion 16, a bead 20 is formed along the door front-rear direction as a protrusion having a mountain-like cross section toward the inside in the vehicle width direction.

As shown in FIG. 2, a lower molding 22 extending in the front-rear direction of the door is attached to the lower end of the side door 10, and the lower molding 22 is made of vinyl chloride or rubber.

As shown in FIG. 1, the door lower molding 22
Is a mounting portion 24 mounted on the lower end of the side door 10.
And an extended portion 28 extending downward from the attachment portion 24 and abutting on the rocker outer panel 26.
A mounting recess 30 having a U-shaped cross section is formed from above. The outside of the mounting recess 30 of the mounting portion 24 has a cross section U
Insert 3 made of stainless steel or spring steel
2 are buried. A fold 34 inclined in the direction of the bottom 30 </ b> A protrudes from the inner facing surface of the mounting recess 30, and the hemming portion 1 of the side door 10 is formed in the mounting recess 30.
6, these folds 34 sandwich the hemming part 16 of the side door 10, and the hemming part 16 and the mounting recess 3
0 is fitted.

The folds 34 are provided at positions not in contact with the hemming sealer 18.

The inner wall 30B of the mounting recess 30 in the vehicle width direction.
A claw portion 36 as a protrusion is formed on the upper end of the mounting recess 30 toward the inside of the mounting recess 30. The claw portion 36 is formed along the door front-rear direction, and the door inner panel 14
To bead 20 from above the door.

The extension portion 28 gradually becomes thinner toward the lower end portion 28A. When the extension portion 28 comes into contact with the rocker outer panel 26, the portion extends from an imaginary line position in FIG. 1 to a solid line position in FIG. To move to.

As shown in FIG. 1, the door inner panel 1
The weather strip 40 is attached to the lower surface 14B of the rocker outer panel 2 when the side door is closed.
6 so as to be in close contact therewith.

Next, the operation of this embodiment will be described. In the under door molding mounting structure of the present embodiment, the door under molding 2
2 is attached to the lower end of the side door 10, the mounting recess 30 of the lower door molding 22 fits into the hemming portion 16 between the door outer panel 12 and the door inner panel 14 at the lower end of the door, and the projection of the lower door molding 22. 36 engages with the bead 20 formed in the vehicle width direction inward in the vicinity of the upper side of the hemming portion 16 at the lower end of the door, and formed into a mountain shape in cross section. Fixation is ensured.

Therefore, in the under door molding mounting structure of this embodiment, the fixing screw is not used unlike the conventional structure, so that the area required for attaching the screw to the mounting portion 24 of the door lower molding 22 is not used. Need not be secured, and the size of the door lower molding 22 can be reduced. And mall under door 2
At the time of assembling, screwing work is not required at the time of assembling, so that assembling workability is improved, and since a fastening element such as a screw is not required, low cost and light weight can be achieved.

In the door lower molding mounting structure of this embodiment, the vertical positioning of the door lower molding 22 to the lower end of the door is performed by the bead 20 at the lower end of the door. To prevent the hemming sealer 18 from being damaged at the time of assembly, which occurs when positioning the door lower molding 22. Further, since the height of the bead 20 is constant as compared with the thickness of the hemming sealer 18, stable fitting is possible.

Furthermore, in the lower door molding mounting structure of the present embodiment, when the hemming sealer 18 is applied, the lower end of the door is formed near the upper side of the hemming portion 16 in the shape of a cross section toward the inside in the vehicle width direction. Since the bead 20 also functions as a guide and a dam, the application work of the hemming sealer 18 becomes easy.

In the under door molding mounting structure of this embodiment, the door under molding 22 is formed of vinyl chloride or rubber, and the insert 32 made of stainless steel or spring steel is embedded outside the mounting recess 30. Instead, the door lower molding 22 may have a two-layer structure of a soft resin and a hard resin in place of the insert 32.
