Description

[Detailed Description of the Invention] The present invention relates to a double-structured radiator grill for automobiles, etc.

Synthetic resin materials are increasingly being used in radiator grills for automobiles and the like due to design requirements.

Polycarbonate in particular has an excellent appearance, but
It has the property of being prone to cracking when it comes into contact with oil, gasoline, etc. in a state with large thermal distortion and internal stress.

Therefore, since it is not possible to mount the grille directly opposite the radiator, it is conceivable to have a double structure in which an inner grille is provided on the engine room side and an outer grille made of polycarbonate is supported by this inner grille.

In this case, if the polycarbonate is made transparent, an excellent appearance can be obtained, but if water droplets, dust, etc. adhere to the back side, the appearance will be impaired.

As a countermeasure to this problem, an inner seal may be considered, but since the thermal distortion is large, a seal that allows this has the problem of being expensive. Also, simply 2
There is a problem in that it is difficult to remove water droplets and dust adhering to the back surface of the outer grille only by using a layered structure.

The present invention was developed in view of the above-mentioned problems, and even when an outer grill made of resin such as polycarbonate is provided, water droplets and
An object of the present invention is to provide a radiator grille with a double structure from which dust etc. can be easily removed.

This invention consists of an inner grille placed on the outside of the radiator facing the radiator, and a structure that can be thermally expanded and contracted in the vehicle width direction and in the longitudinal direction so as to cover the part of the inner grille that is not provided with cooling air passage holes on the outside of the inner grille. The above object is achieved by including a resin outer grille attached to the inner grille, and the inner grille is provided with an opening that allows the backside of the outer grille to be cleaned from the inside of the vehicle body.

Further, the above object is achieved by forming the opening into a lattice-like opening provided with longitudinal ribs.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, this embodiment includes an inner grille 2 disposed on the outside of a radiator 1 facing the radiator 1 of an automobile (overview not shown), and cooling air passage holes 3 on the outside of the inner grille 2. The inner grille 2 has an outer grille 4 made of polycarbonate attached to the inner grille 2 so as to be able to expand and contract thermally in the width direction and longitudinal direction of the vehicle body so as to cover the parts that are not provided. An opening 6 is provided to enable cleaning of the back surface 5 of the outer grille 4.

The inner grille 2 is long in the vehicle width direction and divided into upper and lower sections by a boundary wall 7 which is horizontal in the vehicle width direction, and has a number of lattice-shaped cooling air passage holes 3 in its lower half, and a large number of cooling air passage holes 3 in its upper half. The openings 6 are arranged respectively.

The opening 6 is long in the width direction of the vehicle body and consists of five lattice-shaped openings 9 partitioned by longitudinal ribs 8 at four locations in the inner width direction. This lattice-shaped opening 9 has a width and height that allow insertion from behind the finger.

The boundary wall 7 is provided on the upper part of the inner grille 2.
An upper surface 10 is formed parallel to the upper surface 10, which rises substantially perpendicularly to the inner end of the vehicle body, and has a rising portion 10.
A is formed, and vertical seats 11, 12A, and 12B are formed at the widthwise central portion and both ends of this rising portion 10A at positions that further protrude into the vehicle body.

This seat 11 is provided with a mounting hole 11A,
Further, pins 13 are provided on the seats 12A and 12B to protrude outward in the longitudinal direction of the vehicle body.

An inner grille 2 is located at the lower surface of the boundary wall 7.
Seat seats 14, 15A, 15 consisting of rectangular recesses opening outward to the vehicle body at the center and both ends in the width direction.
B is formed.

The seat 14 is provided with a mounting hole 14A,
Further, pins 13 protruding outward in the longitudinal direction of the vehicle body are provided on the seats 15A and 15B.

The outer grille 4 has the same length as the inner grille 2 in the width direction of the vehicle body, and has an inverted U-shape in longitudinal section in the longitudinal direction of the vehicle body.

When attached to the inner grille 2, the upper side of this inverted U-shape, that is, the outer grille upper surface portion 20A, protrudes inward to the vehicle body so as to cover the inner grille upper surface 10, and extends further into the vehicle body at the center and both end positions in the width direction. Attachment seats 21, 22A, and 22B are provided at protruding positions that stand up in the vertical direction.

These mounting seats 21, 22A, 22B are provided with mounting holes 21A, 23, 23 provided corresponding to the seats 11, 12A, 12B, respectively.

The lower side of the inverted U-shape of the outer grille 4, that is, the lower surface portion 20B of the outer grille, is provided with a catch seat 14 on the inner grille 2 side, when attached to the inner grille 2.
Mounting seats 24, 25A, 25B that stand up vertically at positions protruding inward of the vehicle body are further provided at the center and both ends in the width direction corresponding to 15A and 15B, and both ends in the width direction of the lower half of the inner grille 2 are covered. A protrusion 26 is provided.

The mounting seats 24, 25A, 25B are connected to the mounting holes 14A and pins 13 of the seats 14, 15A, 15B.
Attachment holes 24A and 27 are provided correspondingly to each other.

The mounting holes 23, 27 in the mounting seats 22A, 22B, 25A, 25B are elongated in the width direction,
When the pins 13 are fitted, the outer grille 4 is allowed to expand and contract in the width direction relative to the inner grille 2.

Mounting holes 11A, 1 in the seats 11, 14
4A is made larger than the outer diameter of a mounting bolt (not shown), so that the mounting position of the outer grille 4 relative to the vehicle body (not shown) can be adjusted.

When attaching the outer grille 4 to the inner grille 2, attach the mounting seats 22A, 2 on the left and right sides of the outer grille 4.
Mounting holes 23, 27 in 2B, 25A, 25B
Inner grill 2 left and right catch seats 12A, 12B, 1
5A, 15B, and bolts (not shown) into the mounting holes 21A, 24A in the mounting seats 21, 24 in the center of the outer grille 4 and the mounting holes 11A, 14A in the seats 11, 14 in the center of the inner grille 4. (omitted) and tighten to secure.

The upper surface portion 20A of the outer grille 4 and the upper surface portion 10 of the inner grille 2 are connected to each other in the attached state.
As shown in the figure, they are slightly spaced apart in the vertical direction.

In the embodiment described above, since the inner grille 2 is provided with the grid-shaped opening 9 into which fingers can be inserted, it is possible to easily wipe off adhering substances such as water droplets and dust on the back surface 5 of the outer grille 4 from the inside of the vehicle body. becomes.

Furthermore, since the outer grille 4 is placed in a floating state with respect to the inner grille 2, it has the advantage that distortion due to the heat of the radiator can be tolerated within a certain range, and the accumulation of internal stress within the outer grille 4 can be prevented. .

In addition, in the above embodiment, by providing the vertical ribs 8 in the opening 6, even if a part of the worker's weight is applied to the upper surface portion 20A of the outer grille or the rising portion 10A of the inner grille 2 during cleaning of the outer grille 4, it will not easily break. However, as long as the opening allows the rear surface to be cleaned, it is not limited to having vertical ribs, and may have diagonal ribs, or may not have ribs.

Since the present invention is configured as described above, even when a transparent resin outer grill is provided, water droplets, dust, etc. attached to the back surface can be easily removed, and thermal expansion and contraction of the outer grill is allowed. This has an excellent effect in that an outer grille made of a resin such as polycarbonate, which has large heat expansion and contraction and is easily broken, can be easily attached.
