Description

The present invention relates to an assembled structure including a front grille for a vehicle.

Various other members are conventionally assembled to the front grill for vehicles. As a method of assembling other members to the front grille, a method using clips or screws is generally used. For example, Patent Document 1 discloses that the front grille 8 and the bumper 2 are assembled with clips, and the weight 13 is screwed to the front grille 8 .

In recent years, various functions and designs have been required for the front grille, and along with this, the shape and design of the front grille have also become complicated. As the shape and design of the front grille become more complicated, the front grille is sometimes divided into two parts, an outer grille exposed on the front side of the vehicle and an inner grille arranged on the back side of the outer grille.

By the way, when the outer grille and the inner grille are assembled with clips or screwed together, it is necessary to provide mounting seats for the clips and screws on the rear surface of the outer grille. However, the rear surface of the grille outer has a complicated shape with various vertical walls represented by reinforcing ribs. For this reason, the rear surface of the grille outer is subject to considerable restrictions in terms of molding, and in particular, there is a problem that it is difficult to provide the mounting seat on the portion of the rear surface of the grille outer surrounded by the vertical wall. On the other hand, if the relative positions of the ends of the grille outer and the grille inner change freely, abnormal noise may be generated during running, and damage may occur in some cases.
Therefore, there is a demand for a structure capable of suppressing free relative positional changes of the grille outer and the grille inner, particularly at the end portion.

Hereinafter, the vehicle front grill in the assembly structure of the present invention may be simply referred to as the front grill of the present invention, the front grill of the embodiments, or the like.

The assembly structure of the present invention includes a vehicle front grill having an outer grille and an inner grille, as well as a body side member.

The grille outer of the vehicle front grill has an outer body and a terminal portion of the outer body, that is, a standing wall extending from the outer body to the rear side at the terminal portion of the outer body. Of the grill outer, the area surrounded by the outer terminal portion and the vertical wall is a region that is more difficult to remove from the mold than other areas due to the convenience of being surrounded by the outer terminal portion and the vertical wall.

Here, in the assembly structure of the present invention, the inner end portion of the grill inner is arranged in the surrounding area of the grill outer. Since the inner end portion is the end portion of the grille inner, it is a portion that is likely to change in state due to deformation during running, etc., and such an inner end portion is likely to change in position relative to the outer end portion. I can say.

If the relative positions of the inner terminal portion and the outer terminal portion change freely, problems such as abnormal noise will occur. Therefore, it is necessary to suppress free positional changes of both. However, due to the molding restrictions described above, it is difficult to provide a mounting seat for fixing the inner terminal portion to the outer terminal portion in the vicinity of the surrounding area of the outer terminal portion.

In the assembly structure of the present invention, by sandwiching the inner terminal portion under such conditions between the outer terminal portion and the restricting portion of the body-side member, the relative movement of the inner terminal portion to the outer terminal portion is achieved. Suppress position change. In addition, in the assembly structure of the present invention, the inner terminal portion is sandwiched between the outer terminal portion and the restricting portion instead of being fixed to the outer terminal portion. There is no need to provide a mounting seat.
The assembled structure of the present invention will be described below for each component.

Various vehicle components such as an air intake duct, a radiator, and an engine are arranged behind a vehicle front grill mounted on the vehicle. A grille outer in a typical vehicle front grill is provided with through holes for supplying air thereto. The grille outer in the front grille of the present invention can also have through holes.

The grill outer has an outer body and vertical walls as described above. Although the shape of the outer body is not particularly limited, it is preferable that the outer body has a substantially plate shape with through holes. When the outer body has through holes, the number of through holes may be singular or plural. When having a plurality of through-holes, the outer main body may have a shape such as a grid shape or a net shape, for example.

The outer body has an outer terminal portion. The outer terminal portion is the terminal portion of the outer main body, and is the portion where the vertical wall is provided. That is, only a part of the terminal portion of the outer main body may be the outer terminal portion, or the entire terminal portion of the outer main body may be the outer terminal portion. In other words, the standing wall may be provided only on a portion of the terminal portion of the outer main body, or may be provided on the entire terminal portion of the outer main body.

The vertical wall may extend from the outer main body to the back side at the outer terminal portion, and may extend from the front surface of the outer main body toward the back side, or may extend further from the back side of the outer main body toward the back side. In any case, the length and shape of the standing wall are not particularly limited.

The angle formed by the vertical wall and the outer body is also not particularly limited. It can be said that the superiority of Preferable ranges of the angle θ are 0°<θ<90°, 10°<θ<70°, and 15°<θ<50°.

By the way, when the grille outer has a through hole, when the vehicle is viewed from the front side of the vehicle, vehicle components such as an air intake duct are visible through the through hole of the grille outer, which may impair the design of the vehicle as a whole. For this reason, it is desired that the inner grille, which is arranged on the back side of the outer grille, has a blinding function to cover the components of the vehicle.
In addition to air, rainwater and the like may also enter the through holes of the grill outer. For this reason, the grill inner has a water receiving function to prevent rainwater from entering the back side of the grill outer through the through hole, and a function to adjust the flow of air supplied to the intake duct, radiator, etc. through the through hole. A rectifying function is also desired.
Therefore, the grille inner in the front grille of the present invention can have a blindfold function, a water receiving function, and a rectifying function.

The grill inner has an inner end. The inner terminal portion is the terminal portion of the grill inner and is a portion arranged in the area surrounding the grill outer on the back side of the outer body. Therefore, it can be said that at least the inner terminal portion of the grill inner is arranged on the rear side of the grill outer. The other portion of the grill inner may be arranged on the rear side of the grill outer like the inner terminal portion, but its position is not particularly limited. For example, the portion of the grill inner other than the inner terminal portion may enter the through hole of the grill outer, or may be exposed on the front side of the grill outer through the through hole.
By the way, the inner terminal portion may be any terminal portion of the grill inner, but when the amount of positional change of the inner terminal portion is large, the effect of the present invention of suppressing the relative positional change of the inner terminal portion is particularly remarkable. be. From this point of view, it can be said that the inner terminal portion of the front grill of the present invention is preferably the longitudinal terminal portion of the grill inner.
The grill inner may cover the entire rear surface of the grill outer, or may cover only a portion of the rear surface of the grill outer.

The inner terminal portion of the grill inner is not particularly limited as long as it has a shape that can be arranged in the surrounding area of the grill outer, that is, a shape that can be inserted between the outer terminal portion and the vertical wall. The inner terminal portion may have, for example, a substantially flat plate shape having an inner facing portion facing the outer terminal portion. Alternatively, it may be in the shape of a bent plate or a curved plate having the inner facing portion and the inner standing wall portion facing the standing wall.

The body-side member is a member different from the front grille of the present invention, and at least the restricting portion of the body-side member is arranged on the body side with respect to the front grille, that is, on the back side of the front grille.
The body-side member may be the body itself, or may be a vehicle component other than the body, such as an intake duct or radiator. Alternatively, the body-side member may be a member that is separate from the vehicle component and attached to the vehicle component.

The restricting portion of the body-side member may have any shape as long as it can sandwich the inner terminal portion between it and the outer terminal portion of the grille outer.
Here, the inner terminal portion may be sandwiched between the outer terminal portion and the restricting portion, and may be in contact with one or both of the outer terminal portion and the restricting portion, or may not be in contact with both of them. Also good. Even if the inner terminal portion is not in contact with the outer terminal portion and the restricting portion, if it is sandwiched between them, it is possible to suppress relative positional change of the inner terminal portion with respect to the outer terminal portion. Of course, the smaller the distance between the inner terminal portion and the outer terminal portion and the distance between the inner terminal portion and the restricting portion, the smaller the amount of change in the position of the inner terminal portion relative to the outer terminal portion. Therefore, from this point of view, it is preferable that the distance between the inner terminal portion and the outer terminal portion and the distance between the inner terminal portion and the restricting portion be small.

Specifically, the preferred distance between the inner terminal portion and the outer terminal portion is in the range of 10 mm or less, 7 mm or less, 5 mm or less, and 3 mm or less. Similarly, the preferred distance between the inner terminal portion and the restricting portion is within the range of 10 mm or less, 7 mm or less, 5 mm or less, and 3 mm or less.
If the distance between the inner terminal portion and the outer terminal portion and/or the distance between the inner terminal portion and the restricting portion are within the above ranges, the relative positional change of the inner terminal portion with respect to the outer terminal portion can be effectively controlled. can be suppressed. Further, since the inner terminal portion is simply sandwiched between the outer terminal portion and the restricting portion, a mounting seat or the like for fixing the inner terminal portion is not required. That is, it can be said that the inner end portion of the mounting structure of the present invention is a free end without a mounting seat.

The shape of the outer terminal portion and the restricting portion sandwiching the inner terminal portion is preferably a shape capable of effectively inhibiting the positional change of the inner terminal portion.
Specifically, the outer terminal portion preferably has a side that can make line contact with the inner terminal portion or a surface that can make surface contact with the inner terminal portion on the front side of the direction in which the inner terminal portion can move. In this case, it is preferable that the inner terminal also have a side that can be in line contact with the outer terminal or a surface that can be in surface contact.
It is also preferable that the restricting portion has a side that can make line contact with the inner terminal portion or a surface that can make surface contact with the inner terminal portion on the front side in the direction in which the inner terminal portion can move. In this case, it is preferable that the inner terminal portion also has a side that can be in line contact with the regulating portion or a surface that can be in surface contact.

It is also preferable to interpose an elastic member such as rubber or polyurethane foam in a compressed state between the inner terminal portion and the outer terminal portion and/or between the inner terminal portion and the restricting portion. In this case, the inner terminal portion can be fixed between the outer terminal portion and the restricting portion due to the elasticity of the elastic member. Alternatively, it is also preferable to bond the inner terminal portion and the outer terminal portion and/or the inner terminal portion and the restricting portion with an adhesive such as a double-sided tape.
In these cases, it can be considered that the inner terminal portion and the outer terminal portion and/or the inner terminal portion and the restricting portion are in contact with each other.
Also, in these cases, it is possible to efficiently suppress relative positional changes of the inner terminal portion with respect to the outer terminal portion.

In order to stably sandwich the inner terminal portion of the grill inner, it is preferable that at least the regulating portion of the body-side member and at least the outer terminal portion of the grill outer have a certain degree of rigidity. Furthermore, it is preferable that the restricting portion and the outer terminal portion are light to some extent for the convenience of being mounted on the vehicle. Taking these into consideration, resin materials typified by acrylonitrile-butadiene-styrene copolymer synthetic resin (ABS), polycarbonate (PC), polymethyl methacrylate (PMMA), etc. are used as materials for the restricting portion and the outer terminal portion. is preferred.
For reference, the rigidity of the inner terminal portion of the grill inner may be lower than that of the restricting portion and the outer terminal portion. Therefore, the material of the inner terminal portion may be the same as the material of the restricting portion and the outer terminal portion, or may be lower in rigidity than the material of the restricting portion and the outer terminal portion, such as polypropylene (PP) or elastomer. It can be.

In the assembly structure of the present invention, a mounting seat may be appropriately provided in a region other than the enclosing region, that is, in a region where a mounting seat may be provided. The mounting seat provided in the area other than the enclosing area may be provided on the grill outer or may be provided on the grill inner. In this case, the inner grille can be fixed to the outer grille by means of mounting seats provided in areas other than the enclosing area.
