Description

[Detailed Description of the Invention] The present invention relates to an automobile door lining structure that expands direct lateral visibility through the door.

In order to expand the direct field of view from the driver's seat, especially the side view through the door located on the passenger's seat, and to further improve the reliability of safety confirmation, it is effective to provide a see-through window in the door body. It is said that there is.

However, in order to form a see-through window in a door body, it is necessary to either attach window glass to each opening in the outer panel and inner panel that make up the door body and cover the area between the edges of the openings of both panels with another member to create a double window structure, or to bend the edge of the opening of the inner panel to the inside of the outer panel and join and fix joining flanges provided on the opening edges of both panels and attach the window glass to this joint.

However, in a double-glazed window structure in which both panels are fitted with window glass, the weight of the door body becomes too heavy, so the opening edge of the inner panel is generally bent and joined to the opening edge of the outer panel. This joint flange is fixed and a window glass is attached to this joint flange.

By the way, if the opening edge of the inner panel is deeply bent (narrowed down), cracks will appear at the corner. Therefore, in the past, the corners were notched and bent in advance, and a separate member was welded to the cutout for finishing, or the opening edges of both panels were joined with a separate member to avoid cracks. However, in both cases, the joint between the inner panel and another member is exposed inside the vehicle interior, impairing its appearance (beauty of the vehicle interior) and increasing the number of parts. There is a problem that manufacturing costs increase.

This invention was developed to solve the above problems, and improves the appearance of the door (the aesthetics of the passenger compartment) by making it possible to line the inside of the door body, which was impossible with doors equipped with see-through windows. It is an object of the present invention to increase the rigidity of this inner lining while improving the workability of installing it and the workability of joining the inner panel and the outer panel.

In order to achieve the above object, the present invention provides an opening in the door body composed of an inner panel and an outer panel, and attaches a weather strip to the joint flange of the outer panel and inner panel joined to form the opening. In an automobile door in which a window glass is attached to form a see-through window, an indoor end of a frame-shaped lining formed to cover an indoor side peripheral wall of the see-through window is bent along the surface of the inner panel. Then, the bent portion is fixed to the inner panel with a retainer. Further, the outdoor end of the lining is bent parallel to the joining flange to form a flange, and at least the inner peripheral edge of the flange is covered with an indoor lip provided on the weather strip to form the joining flange. It has a configuration in which it is pressed and fixed.

By adopting such a configuration, bent portions are provided at the indoor end and the outdoor end of the frame-shaped lining, respectively, to increase the rigidity (strength) of the lining, while also increasing the rigidity (strength) of the lining. The inner peripheral wall and the joint between the inner panel and the outer panel are covered with a lining.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In FIGS. 1 and 2 showing an embodiment of the present invention, a door body 2 having a sash 1 forming a door window mounted on the top thereof is composed of an outer panel 3 and an inner panel 4, each of which has a door window. 3 and 4 are provided with openings for forming a see-through window 5.

Further, a joining flange 6 is formed on the opening edge of the outer panel 3 by being slightly recessed from the outer surface of the panel 3, and a joining flange 7 is formed on the opening edge of the inner panel 4 to be joined and fixed to the joining flange 6. is formed.

Here, the joining flange 7 of the inner panel 4
is formed by the method described below.

First, as shown by the two-dot chain line in FIG. 5, a predetermined position of the inner panel 4 is punched out. During this punching, the corner portions are pre-cut according to the bending depth of the inner panel 4, that is, the drawing depth from the general surface of the inner panel 4 to the joining flange 7 (generally the thickness of the door body 2). Make a cutout larger than the transparent window 5.

Next, the periphery of the punched portion is bent toward the outer panel side, and the joining flange 7 is bent to form the joining flange 7. Since a notch has been formed in the corner portion in advance, the joining flange 7 is bent onto the general surface of the inner panel 4. It can be sufficiently displaced to the outside of the room. It should be noted that the periphery of the opening of the inner panel 4 where the joining flange 7 is formed in this way, that is,
The indoor peripheral wall of the see-through window 5 is not continuous, and as shown in FIGS. 4 and 5, a notch 8 is left due to the punching process. covered with.

That is, as shown in FIGS. 1 and 2, the inner lining 9 is formed into a frame shape that covers the indoor side peripheral wall of the see-through window 5 formed in the door body 1, and its indoor side end is It is bent along the general surface of the inner panel 4. Further, the outer panel 3 and the inner panel 4 are attached to the outdoor end of the lining 9.
Flanges parallel to the joining flanges 6 and 7 provided on the front side are provided, and these are integrally molded from synthetic resin.

The outer circumferential portion of the inner lining 9 is made of a resin material or the like, and is fixed to the general surface of the inner panel 4 with a retainer 10. In addition, by recessing the part of the inner panel 4 where it overlaps with the lining 9 more shallowly than other parts, consideration is given so that the surface (inner surface) of the lining 9 and the surface (inner surface) of the inner panel 4 are approximately on the same plane. has been done. Additionally, the outdoor end of the lining 9 (the flange provided at the edge of the opening) is attached to the inner panel 4 using an adhesive 13 such as double-sided adhesive tape or the like.
It is temporarily fixed to the joint flange 7 of. 11 is a mounting hole for the retainer 10, and 12 is a bag-shaped sheet made of soft resin that improves the sealing performance of the retainer 10.

On the other hand, a weather strip 1 is attached to the joined flanges 6 and 7 (hereinafter referred to as the joined flange portion).
A window glass 14 is attached via 5. During this installation, the flange provided on the inner lining 9 along with the joining flange portion is also covered with the lip 16 of the weather strip 15.
The flange of the inner lining 9 is pressed and fixed to the joining flange portion using the pinching force of 6. 17 is a sealing material such as butyl tape for sealing between the inner panel 4 and the lining 9; 18 is a stiffener attached to the inner panel 4 to reinforce the door body 2; 19
20 is an armrest that also serves as the inside handle of the door, and 20 is an inside handle.

That is, the window glass 14 covering the see-through window 5 formed in the door body 2 is attached on substantially the same plane as the outer panel 3, and the opening edge of the inner panel 4 (joint flange 7) is attached to the opening edge of the outer panel 3 (joint flange 6). In order to reduce the number of parts by directly connecting the window to the window, the present invention covers the indoor side peripheral wall of the see-through window 5 with a frame-shaped lining 9. For this reason, there is no need to finish the joint between the outer panel 3 and the inner panel 4 and the periphery of the opening of the inner panel 4, which is narrowed deeply toward the outer panel 3. At the same time, it is possible to reduce the manufacturing cost of the door. The appearance of the vehicle (the aesthetic appearance of the vehicle interior) can be improved.

In addition, the inner lining 9 is formed into a frame shape, and its indoor end is bent along the surface of the inner panel 4, and its outdoor end is provided with a flange parallel to the joining flange 7. The bending increases the rigidity of the lining 9 and improves the ease of handling when assembling the lining 9 to the door body 2.

Furthermore, the indoor side end of the lining 9 is fixed to the inner panel 4 by the retainer 10, and the indoor side end (flange) is pressed and fixed to the joint flange part by the lip 16 of the weather strip 15. In addition, due to the synergistic effect with the above-mentioned improvement in structural rigidity, it is possible to prevent deformation due to external forces or thermal changes, and to prevent falling off from the inner panel 4. Moreover, the flange of the inner lining 9 is covered with the lip 16. There is no need to use separate parts for terminal processing.

In the above embodiment, the flange of the inner lining 9 is temporarily fixed to the joint flange using double-sided adhesive tape, etc., and these are sandwiched and locked by the lip 16, but the double-sided adhesive tape or the like may be omitted, or the third As in the embodiment shown in the figure, the lip that sandwiches the joining flange portion and the lip 16 that covers and locks the flange of the lining 9 may be made independent.

As explained above, according to the present invention, since the indoor peripheral wall of the transparent window and its vicinity are covered with the frame-shaped lining, the joint between the inner panel and the outer panel, The indoor side peripheral wall of the see-through window (the narrowed part of the inner panel) is not exposed indoors. Therefore, there is no need to finish the joint between the inner panel and the outer panel and the vicinity thereof, so manufacturing costs can be reduced without impairing the appearance of the door body. In addition, the lining that covers the indoor peripheral wall of the see-through window and its vicinity is formed into a frame shape, and has bent portions at the indoor and outdoor ends, so that the lining alone has high rigidity. Become.
Therefore, even if the inner panel is simply fixed to the inner panel using the retainer and the weather strip, deformation and falling off of the inner panel can be reliably prevented.
