Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a molding mounting structure for an automobile grill.

[Prior Art] A radiator grille that guides cooling air to an engine room of an automobile, particularly to a radiator, is generally molded from synthetic resin. Headlamp rims, also made of synthetic resin, are placed on both sides of the radiator grille to cover the periphery of the headlamp. The radiator grille and headlamp rim are fixed across the front wall of the vehicle body, specifically across three members: the front fender, the radiator core support, and the front apron.

A gap is provided between the radiator grill and the headlamp rim to prevent the radiator grill from deforming after molding or due to heat from the radiator.

In the mounting structure disclosed in Japanese Unexamined Patent Publication No. 56-34542, in order to eliminate the gap between the radiator grille and the headlamp rim, the two are integrally molded via a bellows-shaped connecting portion. However, if the left and right head lamp rims are the same, integrally molding them is not necessarily advantageous in terms of cost.

In the mounting structure disclosed in Japanese Utility Model Application Publication No. 55-16904, a radiator grill is constructed by combining common parts divided into a plurality of parts.

In the mounting structure disclosed in Utility Model Publication No. 58-1381, the frame of the radiator grille has a U-shaped cross section,
A number of holes are provided at intervals in the vehicle width direction on a rising wall formed integrally with the upper wall of the frame, and a number of insertion pieces are formed on the rear edge of the molding having a U-shaped cross section. When the stopper cut upward from the stopper is pushed into the hole in the rising wall, the stopper elastically restores itself and hits the rising wall and cannot be passed through. However, with the above-described mounting structure, when the radiator grille comes into contact with an obstacle, cracks tend to occur around the upright wall of the radiator grille, and there is a risk that the molding may partially come off from the frame.

[Problems to be solved by the invention] The purpose of the invention is to connect the radiator grille and the head lamp rims on both sides by a molding, suppress excessive thermal deformation, and obtain a well-balanced assembly with a sense of unity as a whole. An object of the present invention is to provide a molding mounting structure for an automobile grill.

[Means for Solving the Problems] In order to achieve the above object, the configuration of the present invention is such that the front surface of the radiator grille and headlamp rim has a cross section S in which the upper half is recessed rearward and the lower half protrudes forward. A projecting strip extending in the width direction of the vehicle is formed, and a projecting wall protruding upward is integrally formed on the rear edge of the lower wall of each of the projecting strips, and a projecting wall protruding upward is integrally formed on the rear edge of the lower wall of the metal molding having a U-shaped cross section. A retaining wall having an inverted U-shaped cross section is integrally formed, the molding is engaged with the lower half of each protrusion, and the retaining wall is engaged so as to sandwich the protruding wall.

[Function] The radiator grille and headlamp rim are each integrally molded with a protrusion that extends in the vehicle width direction and has an S-shaped cross section, with the upper half recessed and the lower half protruding forward.
Engage each ridge with a single metal molding. This restricts the mutual positional relationship between the radiator grill and headlamp rim, provides a sense of unity, and avoids excessive deformation of the radiator grill and unbalanced attachment to the headlamp rim.

[Embodiment of the invention] Fig. 1 shows a radiator grille 1 molded from synthetic resin, a headlamp rim 2 arranged on both sides of the radiator grille 1, and a vehicle width that is engaged with the protrusions 7 and 6 on both sides. It is a perspective view which disassembles and shows the metal molding 3 extended in the direction. radiator grill 1
is equipped with a grid-like opening 4 for feeding air into a radiator (not shown). A protrusion 7 extending in the vehicle width direction and protruding forward is integrally formed on the front lower edge of the radiator grille 1. The headlamp rim 2 is provided with an opening 5 in which the headlamp engages,
A protrusion 6 having the same shape as the above-mentioned protrusion 7 is integrally formed on the lower edge of the front surface.

As shown in FIG. 2, each of the protrusions 7 and 6 actually has an S-shaped cross section, with the upper half concave backward and the lower half protruding forward, so as to have the same wall thickness as the other parts. Eggplant. That is, the upper wall 7d and the intermediate wall 7a form a concave wall, and the intermediate wall 7a and the lower wall 7b form a projecting wall that projects forward. At the rear edge of the lower wall 7b of the protrusion 7,
A projecting wall 7c that projects upward is integrally formed.

The molding 3 is made of a metal plate having a C-shaped or U-shaped cross section and has an upper wall 3a and a lower wall 3b so as to cover the intermediate wall 7a and the lower wall 7b of the protrusion 7. A U-shaped retaining wall 3c is integrally formed.

The automobile grill having the above-mentioned configuration is molded 3
is slid in the longitudinal direction and engaged with the ridges 7 of the radiator grille 1 and the ridges 6 of the headlamp rim 2, and then assembled to the vehicle body by known means. At this time, the upper wall 3a of the molding 3 is the intermediate wall 7a of the protrusion 7.
The lower wall 3b of the molding 3 overlaps with the lower wall 7 of the protrusion 7.
b, and the retaining wall 3c engages with the projecting wall 7c so as to sandwich it therebetween.

In the embodiment shown in FIG. 3, the upper wall 3a of the molding 3
is separated from the intermediate wall 7a of the protrusion 7, and the upper wall 7 of the protrusion 7
d. In this embodiment, the strength of the radiator grill 1 is improved because a closed cross-sectional structure with upper and lower stages is obtained by coupling the protrusions 7 of the radiator grille with the molding 3.

[Effects of the invention] As mentioned above, in this invention, the protrusions of the radiator grille and headlamp rim are connected by a molding, so an overall appearance with a sense of unity can be obtained, and assembly errors between the radiator grille and headlamp rim can be reduced. can be reduced.

Since the mutual positional relationship between the radiator grille and the headlamp rim is regulated by the molding, there is no need to create an unnecessarily large gap between the radiator grille and the headlamp rim in consideration of the complex thermal deformation of the radiator grille. .

The lower wall of the molding and the retaining wall engage with each other so as to wrap around the lower wall of the radiator grille and the retaining wall, and the retaining wall, which has a U-shaped cross section, approaches or comes into contact with the intermediate wall of the ridge to form a closed section. Because of this, there is no fear that the protrusions will be deformed by heat or that the molding will partially come off.

Increasing the thickness of the molding and increasing its rigidity will help improve the strength of the radiator grille, preventing complicated distortions and cracks, and expansion and contraction of the radiator grille in the vehicle width direction will be absorbed by relative movement in the longitudinal direction of the molding. .
