Abstract

PURPOSE:When securing a door trim to an inner trim of car door, to shield rain water or external noise by projecting beads of frame shape on the surface of inner panel while providing a resilient member pressure contacting against said beads on the rear face of door trim. CONSTITUTION:Frame-shaped beads 18 entirely surrounding the surface containing all of fixing holes 13 and working holes 12 are projected from the surface of door inner panel 11. While a resilient member 19 worked into a frame with correspondence to the beads 18 is sticked onto the rear face of door trim 16 to be fixed to the door inner panel 11. In order to fix the door trim 16 to the door inner panel 11, a sealing screen 14 having outer dimension slightly larger than that of beads 18 is applied on the beads 18 then resin clips 7 of door trim 16 are inserted into a plurality of stop holes formed at the outercircumference of beads 18 to contact and sealing screen 14 tightly and entirely over the beads 18 through resilient deformation of resilient member 19.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile door, and more particularly to a door lining structure.

As is well known, a large number of working holes 2, mounting holes 3, etc. are bored in the inner panel 1 of an automobile door as shown in FIG. There is a risk of rainwater etc. entering. Conventionally, this rounding is done by making the central part 1a of the surface of the inner panel 1 concave as shown in the second figure, and attaching the sealing screen 4 to the outer periphery 1b. Formed stop hole 5
The resin clip 7 of the door trim 6 is inserted into the door to complete the door. However, in such a structure, the outer peripheral part of the ceiling screen 4 is not necessarily completely adhered to the inner panel 1, and the central part 1a of the surface of the inner panel l
Rainwater accumulated between the ceiling screen 4 and the sealing screen 4 may flow into the vehicle interior as shown by the arrow, and this incomplete sealing structure also poses a problem in blocking noise from outside the vehicle.

In addition, if the center of the door trim 6 is deformed due to heat or the like, the outer periphery of the door will rise as shown by the imaginary line in FIG. 2, which is unfavorable in terms of quality.

In view of the above-mentioned problems with the door lining structure, the present invention aims to provide a structure that can completely block rainwater and sound that have entered the interior of the vehicle through the mounting holes and working holes in the door inner panel. The purpose is to form a frame-shaped bead on the surface of the inner panel that surrounds the entire surface, press the elastic material on the back of the door trim to the bead, and attach a resin clip around the outside of the bead to connect the door trim. This is a proposal to place a

Embodiments of the present invention will now be described in detail with reference to FIGS. 3 to 5.

3 and 4 show a first embodiment of the present invention. According to the present invention, the surface of the door inner panel 11 has mounting holes 13.
A frame-shaped bead 18 that surrounds the entire surface including all of the working holes 12 is formed in a protruding manner, and the door inner panel 11
An elastic material 19 (for example, urethane foam) processed into a frame shape corresponding to the bead 18 is glued to the back surface of the door trim 16 that is attached to the door trim 16 . Therefore, when attaching the door trim 16 to the door inner funnel 11, the bead 1
By placing a sealing screen 14 with external dimensions slightly larger than 8 on the bead 18 and inserting the resin clips 7 of the door trim 16 into the plurality of stop holes 15 formed around the outer periphery of the bead 18, the sealing screen 4 is brought into close contact with the entire bead 18 due to the elastic deformation of the elastic material 19. In this case, rainwater and sound that enter between the sealing screen 14 and the door inner panel 11 through the mounting hole 13 and the working hole 12 are completely blocked by the close contact between the bead 18 and the sealing screen 14. It is possible to completely prevent rainwater and external noise from entering the vehicle interior.

Further, in the structure of the first embodiment, the above-mentioned stop hole 15 is formed in the frame-shaped recess 20 formed between the outer peripheral part 11b of the door inner panel 11 applied to the outer peripheral part of the door trim 16 and the bead 18. It is characterized by That is, in this structure, the trim board 16 is connected by the resin clip 7.
When the space between the door inner panel a and the door inner panel 11 is strongly tightened, the trim board 16a deforms as shown in an exaggerated imaginary line in FIG. The adhesion between the bead 18 and the ceiling screen 14 is improved, and the outer periphery of the trim board 16a does not warp as in the conventional case.

FIG. 5 shows a second embodiment of the present invention, in which the skin 26b and elastic pad 26c of the door trim 26 are used in place of the elastic material 19 described above.

As shown in the figure, the skin 26b and elastic pad 26c of the door trim 26 extend to the inner peripheral position of the bead 18,
It covers the back surface of the trim board 26a. Therefore,
When the trim board 26a is attached using the resin clip 7, the sealing screen 14 is pressed against the bead 18 due to the elastic deformation of the extension part X of the elastic pad 26c.
It is possible to obtain the same effects as in the first embodiment.

In each of the above embodiments, the structure is explained in which the sealing screen is attached to the door inner panel, but the back side of the door trim itself is water resistant, and the elastic material is made of a material with sealing properties such as closed foam resin. In the end, according to the present invention, by making elastic contact between the bead formed on the door inner panel and the elastic material provided on the door trim, the relationship between the door inner panel and the door trim is improved.
The LL'/V' colors allow for reliable sealing, so even if you are using 1000 x 3, you only need to apply a small amount of adhesive.Strict precision is also required for the work of attaching the sealing screen. Therefore, a structure can be obtained that completely blocks out rainwater and external sounds.
