Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel automobile door. More specifically, it relates to an automobile door having a ventilation function (with the window closed).

Conventionally, ventilation in the interior of an automobile has been achieved by taking in air from the front of the body and discharging it to the outside through air exhaust holes provided on both sides of the rear of the body. However, this alone is not sufficient for ventilation, so windows are opened to let in fresh air. However, opening windows every time ventilation is required is troublesome, and there are problems such as hair becoming messy and dust getting into the eyes.

In view of this, the present invention provides an automobile door that has a ventilation function when the window is closed.

That is, the present invention is such that a gap is formed between a door trim having a rigid reinforcing member having a U-shaped cross section fitted to the lower end of a substrate of the door trim and an inner panel having a service hole at the lower end. The present invention relates to an automobile door which is attached to an automobile door and has an air exhaust hole provided in an inner panel.

Next, the automobile door of the present invention will be explained with reference to the drawings. FIG. 1 is a perspective view showing the inside of an embodiment of the door of the present invention, FIG. 2 is a perspective view showing the outside, and FIG. 3 is a partially enlarged sectional view taken along line X-X in FIG.
FIG. 4 is a perspective view showing the door with the door trim and service hole cover removed. In the drawings, 1 is an outer panel of the door, 2 is an inner panel, and 3 is a window. The inner panel 2 is equipped with a specific reinforcing member at the lower end as described later, and the inner panel has a plurality of service holes 2a, 2b, 2c for installing a window regulator or the like inside the door inner.
is provided. 4 is a service hole cover, which is used to close the service holes 2a, 2b, and 2c after installing a window regulator or the like. Service hole cover 4
is usually a resin sheet, and is attached to the inner panel 2 with double-sided adhesive tape such as double-sided butyl rubber tape. Reference numeral 5 denotes a door trim, which is attached to the inner panel 2 with a locking means such as a clip 6. 7 is a window opening/closing handle, 8 is a door lock, and 9 and 10 are handles.

One of the features of the present invention is that the door trim 5 is installed so that a gap is formed between it and the inner panel 2 at its lower end, and
An air exhaust hole 11 is provided in the door, and indoor air is passed through the inside of the door and is discharged to the outside from the air exhaust hole 11. The service hole cover 4 is provided with an opening, preferably a one-way check valve 12 from the indoor to the outdoor, at a location corresponding to at least one service hole (for example, 2b).

As shown by the arrow in FIG. 3, indoor air enters the door inner through the check valve 12 from the gap between the lower end of the door trim 5 and the inner panel 2, and then enters the inner door through the check valve 12.
The air is discharged to the outside from an air exhaust hole 11 provided in the air.

The check valve 12 allows indoor air to pass into the door inner and prevents dust from entering the room from outside. The check valve 12 can be formed, for example, by making a tongue-shaped cut in a part of the service hole cover 4 and inserting the tongue-shaped piece into the door inner through the service hole 2b as shown in FIG. The location where the air exhaust hole 11 is provided is not particularly limited, and may be, for example, the rear lower end of the inner panel 2.

As a means for providing a gap between the lower end of the door trim 5 and the inner panel 2, as shown in FIG. For example, the mounting surface 6a of the door trim clip 6 may be raised.

The second feature of the present invention is the improvement of the door trim 5. As mentioned above, in order to provide a gap between the lower end of the door trim 5 and the inner panel 2 from the viewpoint of improving ventilation, the mounting seat surface 6a of the clip 6 at the lower end of the inner panel 2 is installed as shown in FIG. When the door trim 5 is raised up, a problem arises in that the door trim 5 becomes wavy over time as shown in FIG. The present invention solves this waving phenomenon in the door trim 5 by attaching a reinforcing member to the lower end of the door trim 5.

FIG. 7 is a plan view showing one embodiment of the door trim used in the present invention, FIG. 8 is a partially cutaway rear view thereof, and FIG. 9 is a sectional view taken along the Z-Z line in FIGS. FIG. 10 is a perspective view showing one embodiment of the reinforcing member used in the present invention. In Figures 7 to 9,
51 is a substrate, 52 is a cushion layer, and 53 is a skin layer. The substrate 51, the cushion layer 52, and the skin layer 53 are laminated in this order and bonded to each other by thermal welding at desired locations. 54 is a heat welded portion. A plurality of reinforcing members 55 having a U-shaped cross section as shown in FIG. 10 are fitted to the lower end of the substrate 51. As shown in FIG. Adhesion may also be used to attach the reinforcing member 55. The peripheral edge of the skin layer 53 is folded back to the back side and fixed to the substrate 51 using fastening means 56 such as a tack. Note that 57 is a clip attachment hole, and 58 is a clip attachment hole.
59 is a door lock mounting hole, and 60 is a handle mounting hole.

However, in the door trim having the above structure, the reinforcing member 5 having a U-shaped cross section is fitted at the lower end thereof.
5, the inner panel 2
Even if it is installed with a gap between the two, the waving phenomenon described above can be completely prevented.

Materials for the reinforcing member 55 used in the present invention include metals such as steel and aluminum alloy, and plastics such as hard polyvinyl chloride.

Substrate 51, cushion layer 52 and skin layer 53
etc. are not particularly limited, and any conventional door trim can be used, for example, the board 51.
Examples of the material include hardboard, particle board, plywood, and plastic honeycomb board. Examples of the cushion layer 52 include foam such as polyurethane foam. Examples of the skin layer 53 include a soft polyvinyl chloride sheet made of leather. .
