Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mounting structure for fixing an article to a mounting position. The mounting structure of the present invention can be used when attaching a radiator grill of an automobile to a vehicle body.

[Prior Art] For example, a radiator grill of an automobile has a designed surface on the front surface, and as seen in Publication of Utility Model Publication No. 61-35468, a flange portion protruding almost parallel to the designed surface is attached to the vehicle body in front of the radiator. It is attached via screws, etc. In other words, it is usually fixed with screws or bolts so that the shaft extends from the front to the rear of the vehicle body.

However, in the case of a structure in which the radiator grille is attached from the front to the rear as described above, the heads of screws and the like are exposed on the designed surface of the radiator grille, which is not desirable in terms of appearance. Therefore, in recent years, as shown in FIG.
01 is provided so as to protrude from the design surface 102 toward the back side, and is installed, for example, from the top to the bottom. In many cases, the installation direction of the door 103 is orthogonal to the conventional installation direction. It has become.

In this way, the heads of the screws 103 and the like are located on the back side of the radiator grille 100, making them difficult to see from the front, which is preferable in terms of appearance.

[Problems to be Solved by the Invention] By the way, in the radiator grill, as shown in FIG. It may be fixed. However, both the radiator support 104 and the bumper 105 are formed separately from the vehicle body, and are attached to the vehicle body in an assembly process. Therefore, if there is a dimensional error during manufacturing or an error during assembly, the radiator grill 1
There will be a difference in the interval dimension (L) between the flange portions 101 in the vertical direction of 00 and the interval dimension (52) between the radiator support 104 and the retainer 106.

In the case of the above-mentioned conventional mounting structure that is mounted from the front to the rear, such dimensional errors can be easily accommodated by making the mounting holes of the flange portions elongated holes. However, in the case of a structure in which the mounting hole is mounted from the top to the bottom as shown in FIG. Can not. Further, since the radiator grill is generally made of hard resin, it is difficult to deform it enough to absorb dimensional errors. Therefore, it is necessary to readjust the position of the radiator support 104, which increases the number of man-hours required for assembly.

The present invention was made in view of these circumstances, and
°The objective is to provide a mounting structure that allows easy mounting even if a dimensional error occurs in the mounting position.

[Means for Solving the Problems] A mounting structure for an article of the present invention that solves the above problems includes a base body, a design surface formed on one surface of the base body, and a design surface that protrudes from the base body toward the back side with respect to the design surface. A mounting structure in which a plurality of mounting parts of an article consisting of a plurality of mounting parts are each fixed to a mounting position by a fixing means having an axial direction substantially perpendicular to a protruding direction of the mounting parts, the plurality of mounting parts At least one of the fixing means is fixed to the mounting position via a displacement member that is deformable in the axial direction of the fixing means.

The attachment part means, for example, a 7-run part, which protrudes from the base to the back side with respect to the design surface.

Conventional means such as screws, bolts/nuts, and clips can be used as the fixing means. The axial direction of this fixing means is approximately perpendicular to the protruding direction of the attachment portion.

The most important feature of the present invention is that at least one of the attachment parts is fixed to the attachment position via a displacement member that is deformable in the axial direction of the fixing means.

As this displacement member, a resin hinge member, a spring member, etc. made of polypropylene or the like can be used. By deforming this displacement member, it is possible to absorb dimensional errors in the mounting position.

[Operations and Effects of the Invention] In the article mounting structure of the present invention, at least one of the mounting portions is fixed to the mounting position via the displacement member. In other words, if a dimensional error occurs and the dimensions of the mounting position differ from the dimensions of the mounting part, a displacement member is interposed and the displacement member deforms to absorb the error and move the mounting part to the mounting position. can be fixed to.

Therefore, according to the mounting structure of the present invention, by fixing one end of the displaceable member to the base of the article in advance, it is only necessary to fix the other end of the displaceable member to the position to be attached. The number of man-hours required can be made the same as in the past. Since dimensional errors can be easily absorbed, the number of assembly steps can be reduced and costs can be reduced.

[Example] Hereinafter, the present invention will be explained in detail using an example. In this embodiment, a lattice-shaped radiator grill 1 as shown in FIG.
As shown in the figure, this is a mounting structure that is attached to the front of a car.

The radiator grill 1 is formed from ABS by injection molding, and includes a base body 10, four first flange portions 11 that protrude and extend from one end of the base body 10 to the back side, and four first flange portions 11 that protrude and extend from the other end of the base body 10 to the back side. It has two second flange parts 12. The first flange portion 11 and the second flange portion 12 each extend in parallel, and each has a mounting hole 13 formed in the center. The surface of the base body 10 opposite to the protruding surfaces of the 17th flange portion 11 and the 27th flange portion 12 serves as a design surface 14.

(Example 1) FIGS. 1 and 3 show the mounting structure of this example. In this mounting structure, a radiator grille 1 is attached to a radiator support 2 and a bumper 3.

The radiator grill 1 is arranged so that the design surface 14 faces forward, and has a first flange portion 11 and a second flange portion 1.
2 extend horizontally. First flange part 1
1 is fixed to a radiator support 2 via a displacement member 4 with screws 20. Further, the twenty-seventh flange portion 12 is fixed to a retainer 30 held at the lower part of the bumper 3 with screws 31.

The displacement member 4 is made of PP, and has thick portions 41 at both ends as shown in FIG. 2, and a deformable hinge portion 42 is formed between the thick portions 41. The thick wall portions 41 at both ends have mounting holes 40, respectively, and as shown in an enlarged view in FIG.
1, and the other thick portion 41 is fixed to the radiator support 2 with screws 20. Therefore, even if there is a misalignment between the position of the first flange part 11 and the position of the radiator support 2, the displacement member 4 deforms at the hinge part 42, so that the two can be easily connected and fixed.

To form this mounting structure, first the first flange portion 11
Prepare a radiator grille 1 in which one thick wall portion 41 of the displacement member 4 is fixed with a rivet 43, and attach the other thick wall portion 41 and second flange portion 12 of the displacement member 4 to the radiator support 2 and the retainer 30, respectively. It can be easily formed by fixing with screws 20.31.

In the mounting structure of this embodiment, no matter which of the distances between the radiator support 2 and the retainer 30 and the distance between the first flange portion 11 and the second flange portion 12 is larger, the hinge portion 42 is deformed in the vertical direction. The dimensional error is absorbed, and the radiator grill 1 can be easily fixed within the range of deformation of the hinge portion 42. Therefore, since there is no need to adjust the position of the radiator support 2, the number of assembly steps can be reduced.

Although only the first flange portion 11 is fixed via the displacement member 4 in this embodiment, it is of course possible to fix the second flange portion 12 and the retainer 30 via the displacement member 4.

(Embodiment 2) FIG. 6 shows the mounting structure of the second embodiment. This mounting structure is the same as in Example 1 except that the configuration of the displacement member is different.

That is, the displacement member 4- is made of spring steel and has a substantially S-shaped cross section, and has a first flange portion 11 in a groove portion having an O-shaped cross section on one end side.
The whole body is fixed with screws 20 so that the other end is in contact with the radiator support 2 and a spring elastic part 44 having a zero-shaped cross section is interposed between the first flange part 11 and the radiator support 2. There is.

In this embodiment, the 17th flange portion 11 and the second flange portion 1
When the distance between the radiator support 2 and the retainer 30 is larger than the distance between the radiator support 2 and the retainer 30, the spring elastic portion 44 is elastically deformed to absorb the dimensional difference and connect and fix the two.
