Description

[Detailed Description of the Invention] This invention relates to a trunk room trim that lines each panel forming the trunk room of an automobile.

Examples of conventional trunk room trims for automobiles include those shown in Figs.
-Refer to Publication No. 120019).
That is, the trunk floor panel 2 forming the trunk room 1, the rear fender panels 3, 3, the panels 4 for the trunk wheel house, and the gasoline tank 5 arranged on the front side of the trunk room 1.
The trunk floor trim 6, trunk side trim 7, trunk wheel house trim 8, trunk front trim 9, trunk rear trim 10, etc. are used as linings to prevent exposure of the panel 5', etc. of the vehicle as separate parts. It is attached to the panels of each part forming the trunk room 1 on the assembly line. It is unavoidable that some assembly errors will occur when each panel forming the trunk compartment 1 is assembled on the vehicle assembly line, and in particular, the fender panels 3, 3 have a trunk floor side panel 12 that is different from the trunk floor panel 2. As shown in the arrow X in Figure 3A, this assembly has a horizontal joint (the flange protrudes in the vertical direction and is dangerous), so when assembling by spot welding, the horizontal joint Discrepancies inevitably occur. Furthermore, since this lateral misalignment occurs on both sides of the luggage compartment 1, the dimension between the two fender panels 3, 3 is either large as shown in Figure 4 (a), or small as shown in Figure 4 (b). In some cases, the size is l, and this size differs from car to car. and,
Even in the longitudinal direction of the vehicle, there are variations in the joints between the trunk floor panel 2 and the trunk rear panel 13, and variations in the attachment of the gasoline tank 5 to the panel 5'. For this reason, in the past, in order to absorb the assembly error of each panel forming the trunk room 1, each trim 6, 7, 8,
9 and 10 are prepared as separate parts and attached to corresponding parts, and the mating parts 14 of each trim part are wrapped to prevent the panel from being exposed (see FIGS. 5 to 7).

However, in the case of such conventional trunk room trim for automobiles, it is necessary to prepare many trim parts depending on the installation location, a large amount of storage space is required on the side of the vehicle assembly line, and there are many types of parts. This requires a lot of management effort, and additionally, an extra lap allowance is required to absorb assembly errors of each panel, which requires the use of additional materials, which is also uneconomical.

This idea was made by focusing on such conventional trunk room trims for automobiles, and the trunk room trim is pre-integrated, and the parts corresponding to the conventional individual component joints, that is, the seams of each panel forming the trunk room, are Multiple folding lines are provided at the corresponding parts, and each panel can be folded and pulled up freely via these folding lines, and each panel can be assembled by selecting and using any of the multiple folding lines. The aim is to solve the problems of the conventional technology by making it possible to absorb errors.

The details of this invention will be explained below based on FIGS. 8 to 12. First, to explain the structure, this automobile trunk room trim 30 includes at least a trunk floor trim part 15, trunk side trim parts 16, 16, and a trunk front trim part 1.
7 are integrally formed.

This state is shown in FIG. That is, FIG. 8 shows an example in which the trunk wheel house trim part and the rear trim part are excluded. However, the invention is not limited to this, and it is also possible to form these parts integrally with the trunk floor trim part 15, trunk side trim parts 16, 16, and trunk front trim part 17.

A trunk floor trim portion 15 corresponding to the joints of each panel forming the trunk room 1
A plurality of bending lines 18 are provided between the trim portion 16 and the other trim portions 16, 16, 17, respectively. For example, three bending lines 18a, 18b, 18c are provided on the base material 19 by pressing, and the skin material 20 is provided with three bending lines 18a, 18b, 18c.
8c does not appear [Figure 9a]. This is preferable in terms of appearance.
For example, hardboard can be used as the base material 19, and vinyl leather, for example, can be used as the skin material 20, and the surface material 20 does not have streaks when bent along an arbitrary bending line 18b. [Figure 9 b]. Furthermore, when a three-layer plastic cardboard is used as the base material 19', as shown in FIG. The height of the three layers is set so that there are streaks, so that there are no streaks on the front side of the skin material 20', the lower mold 21 is preheated, and the upper mold 2 is heated.
By pressing according to step 2, it is possible to create a crease similar to that shown in Fig. 9A. In the example shown in FIG. 10A, two bending lines 18a' and 18b' are provided on the base material 19',
When the skin material 20' is bent along an arbitrary bending line 18b', no streaks appear on the surface of the skin material 20'.
Figure B]. Furthermore, when a two-layer plastic corrugated board is used as the base material instead of the three-layer plastic corrugated board, the base material can be subjected to the creasing process in the same manner as described above.

The plurality of bending lines 18 provided by such creasing or other processes are
It has a function for folding and raising other trim parts [trunk side trim parts 16, 16 and trunk front trim part 17] for the trunk compartment 1, and also for absorbing dimensional errors in assembling each panel forming the trunk compartment 1. . In addition to this bending line 18, in the example shown in FIG. 8, an intermediate bending line 23 is provided from the trunk floor trim part 15 to the trunk front trim part 17. The intermediate bending line 23 is the trunk room trim 3 for this automobile.
0 can be folded in half to reduce the overall size and make it easier to handle, so it may be formed at any location other than the illustrated example, or it may be formed at a plurality of locations.

The trunk floor trim part 15 has an H-shaped slit 2 in a part corresponding to the storage part 25 for the spare tire 24 provided in the trunk floor panel 2.
6 is cut out, and a lid body 28 that can be opened and closed via a bending line 27 is provided there. Note that 29 is a handle.

Next, the effect will be explained. At least trunk floor trim section 15, trunk side trim section 16, 1
6. This automobile trunk room trim 30 in which the trunk front trim part 17 is integrally formed
initially exhibited a flat state as shown by the solid line in Figure 8,
Next, the package is folded inward along the folding line 18 (in the direction of arrow A in the figure) to reduce the packaging area, and if necessary, the entire package can be folded in half via the intermediate folding line 23. In this way, the package area is reduced and prepared on the line side of the automobile assembly line, inserted into the trunk room 1, and there again, the trunk side trim is connected to the trunk floor trim portion 15 via the bending line 18. Part 1
6, 16 and the trunk front trim section 17 (in the direction of arrow B in the figure) and attach them to the corresponding panels, respectively. At this time, since each panel has some assembly dimensional error, one of the plurality of bending lines 18a, 18b, and 18c is selectively used to absorb the assembly dimensional error. For example, if the distance between both fender panels 11 and 11 is small, the bending line 18c is selected and used [first
1], and in the case of a large dimension L, the bending line 18a is selected and used [FIG. 12]. Incidentally, when the trunk side trim parts 16, 16 and the trunk front trim part 17 are raised relative to the trunk floor trim part 15, no streaks appear on the surfaces of the skin materials 20, 20'.

As explained above, according to this invention, at least the trunk floor trim part, the trunk side trim part, and the trunk front trim part are integrally formed, and the structure corresponds to the joint of each panel forming the trunk room. In the area between the trunk floor trim part and other trim parts, there are multiple bending lines for folding and raising other trim parts with respect to the trunk floor trim part, and for absorbing dimensional errors in assembling each of the above panels. This reduces the number of parts compared to conventional trunk trims, simplifies parts management, reduces storage space on the assembly line side, and saves on materials by eliminating the need for extra wrapping. Furthermore, when inserting and installing the panel into the trunk compartment on an automobile assembly line, it is possible to select and use one of the multiple bending lines according to the precision of the car body to absorb errors in the assembly dimensions of each panel. Another effect is that the appearance quality of the interior lining of a trunk room can be expected to be improved since no lines from the bending lines appear.
