Description

The present invention relates to a resin door for a vehicle, which is excellent in fixing strength, weight reduction and dimensional accuracy of a window frame.

As a conventional vehicle door, an iron door whose outer panel and inner panel are made of steel plate has been generally used. However, in recent years, there has been a demand for weight reduction of vehicles, and a resin door in which an outer panel and an inner panel are molded by using a resin material instead of a steel plate has been proposed. Further, in a specific type of vehicle door such as a back door, there is an example in which a resin door is actually put into practical use.

Patent Documents 1 and 2 disclose an automobile panel structure in which the outer panel material is made of a specific resin material and the inner panel is made of a specific fiber reinforced resin material. Further, it is explained that this automobile panel structure is used as a panel structure for a side door, a back door, a sliding door, a hood, a roof and the like.

Patent Document 3 discloses a reinforcing structure of a resin door in which a groove formed by ribs is provided in the outer panel and a reinforcing member is attached to the groove. Further, the drawing shows a swing door (hinge door) to which the reinforcing member is attached.

Patent Document 4 discloses a resin door in which a rib is provided on an outer panel and a side impact bar is attached to the rib. Further, the drawing shows a swing door (hinge door) to which the side impact bar is attached.

Resin doors are superior in terms of weight reduction, but are usually inferior in strength to iron doors. Therefore, in order to put the resin door to practical use, it is necessary to devise a way to improve its strength.

For example, regarding the method of attaching the window frame of a sliding door, in an iron sliding door, the outside of the window frame is fixed by wrapping the outer panel, but the inside (glass side) is fixed without fixing, but the required strength (rigidity). ) Is obtained, so it is generally not fixed. On the other hand, since the resin sliding door is inferior in strength to the iron door, the present inventors considered that it is not preferable to adopt the same configuration as the iron sliding door.

The present invention has been made to solve the above problems. That is, an object of the present invention is to provide a resin door for a vehicle which is excellent in fixing strength, weight reduction and dimensional accuracy of a window frame.

As a result of diligent studies to achieve the above object, the present inventors have found that it is very effective to fix the peripheral edge of the window frame on the outer panel side and the peripheral edge of the window frame on the inner panel side by rivets. The invention was completed. That is, the present invention is specified by the following matters.

[1] A resin door for a vehicle provided with an outer panel and an inner panel, wherein the peripheral edge of the window frame is formed by the peripheral edge of the window frame on the outer panel side and the peripheral edge of the window frame on the inner panel side.
A resin door for a vehicle, characterized in that the peripheral edge of the window frame on the outer panel side and the peripheral edge of the window frame on the inner panel side are fixed by rivets.

[2] The outer panel side window frame peripheral edge has an outer panel side protrusion projecting toward the inside of the door, and the inner panel side window frame peripheral edge projectes toward the inside of the door. The vehicle resin door according to [1], which has a portion, and the outer panel side protrusion and the inner panel side protrusion are fixed by rivets.

[3] The vehicle resin door according to claim 1 or 2, which is a sliding door.

According to the present invention, it is possible to provide a resin door for a vehicle which is excellent in terms of fixing strength, weight reduction and dimensional accuracy of a window frame.

It is a figure which shows one Embodiment (the resin slide door for a vehicle) of the resin door for a vehicle of this invention. It is sectional drawing of the line AA' at the position of the rivet 31.

FIG. 1 is a diagram showing an embodiment of a vehicle resin door of the present invention (vehicle resin sliding door). The vehicle resin slide door 1 shown in FIG. 1 includes an outer panel 11 and an inner panel 12, and is slidably connected to a vehicle body (not shown) by two fixing points 11. One of the fixing points 21 is located in the clevis portion on the front side of the vehicle body, and the other one of the fixing points 21 is a portion where the door striker on the rear side of the vehicle body and the lock are engaged and fixed.

In FIG. 1, the peripheral edge of the window frame is formed by the outer panel side window frame peripheral edge 11a (not shown in FIG. 1) and the inner panel side window frame peripheral edge 12a around the window 13 of the vehicle resin slide door 1. The part is composed. Then, the window frame peripheral edge portion 11a on the outer panel side and the window frame peripheral edge portion 12a on the inner panel side are fixed by the rivet 31. The rivets 31 are used at two locations on the upper side of the window 13 and at three locations on the left and right sides of the window.

FIG. 2 is a sectional view taken along line AA'at the position of the rivet 31. As shown in FIG. 2, the outer panel side protrusion 11b projecting toward the door inner side of the window frame peripheral portion 11a on the outer panel side and the window frame peripheral portion 12a on the inner panel side toward the door inner side. The protruding inner panel side protruding portion 12b is fixed by the rivet 31. As a result, the fixing strength of the window frame is improved. Elastic members 32 for holding the window glass are provided below the peripheral edges 11a and 12a of the window frame, whereby the window glass 33 is held.

In the present invention, the type of the rivet 31 is not limited, and various rivets known to be usable for fixing the resin member and other members can be used.

In the present invention, the fixed position by the rivet 31 is preferably the position shown in FIG. However, the present invention is not limited to this position, as long as the fixing strength of the window frame is improved by fixing the window frame peripheral edge portion 11a on the outer panel side and the window frame peripheral edge portion 12a on the inner panel side. good. For example, the position where the rivet 31 is used on the upper side of the window 13 may be three or more, or may be one in some cases. Further, the positions where the rivets 31 are used on the left side and the right side of the window may be four or more, and in some cases, two or one. Further, it is also possible to use the rivet 31 only on the upper side of the window 13 and use other fixing means (or not use the fixing means in some cases) on the left side and the right side of the window 13 without using the rivet 31. Yes, and conversely, use rivets 31 only on the left and right sides of the window 13 and use other fixing means (or in some cases, do not use fixing means) on the upper side of the window without using rivets 31. Is also possible. Further, it is also possible to use the rivet 31 on only one of the left side and the right side of the window 13 and use another fixing means (or not use the fixing means in some cases) without using the rivet 31 on the other side. is there.

Further, in FIG. 1, a reinforcing member 22 is provided between the two fixed points 21. The shape of the reinforcing member 22 is a band shape extending in the lateral direction, and both ends of the reinforcing member 22 are fixed at the positions of two fixing points 21. The portions (tensioned portions) other than both ends of the reinforcing member 22 are not fixed. The cross-sectional shape of the reinforcing member 12 has two recesses. The reinforcing member 22 is a member that suppresses a movement that tends to rotate about a fixed point 21 due to a pressing force from the inner side surface of the slide door. Providing such a reinforcing member 22 on the sliding door is very effective in improving the strength.

As the resin door for a vehicle of the present invention, the resin sliding door 1 as shown in FIGS. 1 and 2 is preferable, but the present invention is not limited thereto. Since the resin door for vehicles of the present invention is excellent in fixing strength and dimensional accuracy of the window frame, it is also useful as a resin door other than the resin sliding door, for example, a resin swing door (hinge door).

The vehicle resin door of the present invention is advantageous in terms of weight reduction because the main part is made of resin. In the resin door, polypropylene compound is preferable as the material constituting the outer panel 11. As a material constituting the inner panel 12, a sheet molding compound (SMC: a sheet in which fibers are impregnated with a resin) is preferable. Specific examples of the resin for the sheet molding compound include unsaturated polyester resins. Specific examples of the fibers of the sheet molding compound include glass fibers and carbon fibers.

Since the resin door for vehicles of the present invention is excellent in fixing strength, weight reduction and dimensional accuracy of the window frame, resin doors of various vehicles such as automobiles, for example, resin sliding doors and resin swing doors ( It is very useful as a hinged door).
