EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated in detail. The embodiment described below is an example for realizing the present invention, and should be modified or changed as appropriate depending on the configuration of the device to which the present invention is applied and various conditions. The invention is not limited to this embodiment. Further, in each figure, the same components are denoted by the same reference numerals, and redundant explanations will be omitted as appropriate.

<This embodiment>
[Front grill configuration]
FIG. 1 is a front view of a front grill according to this embodiment. FIG. 2 is a back view of the front grill. Further, FIG. 3 is a cross-sectional view taken along the line III--III shown in FIG.

The front grill 30 according to the present embodiment is a plate-shaped member that constitutes the front surface of the vehicle body, as shown in FIGS. 1 to 3. The front grill 30 includes a grill panel 10, a grill base 20, and a front bumper 3. The grill panel 10 and the front bumper 3 are arranged on the vehicle front side of the front grill 30. On the other hand, the grill base 20 is arranged on the vehicle rear side of the front grill 30. Further, the front bumper 3 extends in the vehicle width direction below the grill panel 10.

The grill panel 10 is formed into a plate shape on the vehicle front side. The grille panel 10 is formed into a plate shape on the front side of the vehicle, so that marks, logos, three-dimensional shapes, etc. representing the face of the automobile manufacturer are applied to the front side of the vehicle.

The grill panel 10 is made of resin that is easy to process, such as ABS resin. ABS resin is a resin that combines three types of ingredients: acrylonitrile, butadiene, and styrene, and by changing the composition of the three types of ingredients, resins with different characteristics can be produced. .

Meanwhile, the grill base 20 is made of impact-resistant resin, such as polypropylene (PP). Thereby, the grill base 20 reinforces the strength of the grill panel 10 and supports the grill panel 10 from the rear side of the vehicle. With such a configuration, the front grill 30 is configured by combining the grill panel 10 and the grill base 20.

A plurality of first holes 1 are formed in the upper half of the grill panel 10, as shown in FIGS. 1 to 3. In addition to the function of supplying air to the power chamber, the first hole 1 has the function of decorating the front of the vehicle. As shown in FIG. 1, the first holes 1 are arranged in two rectangular areas separated from each other in the left and right directions. Each of the plurality of left and right first holes 1 is arranged in a grid pattern, and is regularly arranged on the grill panel 10 in the vehicle width direction and the vehicle vertical direction.

Each of the plurality of first holes 1 penetrates the grill panel 10 from the front to the back. Further, as shown in FIG. 2, through holes ER are also formed in regions of the grill base 20 corresponding to some of the plurality of first holes 1. The air that has passed through these is then supplied to a radiator (not shown) or the like. In addition, some of the air and rainwater that have passed through the plurality of first holes 1 enter between the grill panel 10 and the grill base 20. The space between the grill panel 10 and the grill base 20 is difficult to clean, so it is dirty with mud and dust, and the dirt is likely to mix with rainwater.

Further, as shown in FIGS. 2 and 3, first ribs 2 extending toward the rear of the vehicle are formed below the plurality of first holes 1. As shown in FIG. 2, below the plurality of first holes 1 formed in the left rectangular area, two first ribs 2 are provided spaced apart from each other in the left and right directions. The structure of the first rib 2 corresponding to the rectangular area on the right side is the same as that on the left side, so a description thereof will be omitted.

The grille base 20 is formed with a bulging portion 11 that bulges toward the rear of the vehicle. As shown in FIG. 2, the bulging portion 11 is formed in a so-called funnel shape in which the upper end of the vehicle is wide in the vehicle width direction and the width becomes narrower toward the lower side of the vehicle. As a result, the bulge 11 collects rainwater and mud flowing along the inner wall of the grill base 20 to the lower side of the bulge 11 . Further, among the two bulging portions 11, the right bulging portion 11 becomes larger as the distance from the grill panel 10 goes downward (see the rectangular area on the right).

Further, a second hole 12 is formed in the grill base 20 at a position facing the first rib 2. The second hole 12 is provided in the bulge 11 . The bulging portion 11 discharges collected rainwater and mud from the second hole portion 12. By providing the second hole 12 in the bulge 11, the bulge 11 efficiently discharges collected rainwater and mud to the back side of the grill base 20 through the second hole 12.

The first rib 2 of the grill panel 10 extends toward the second hole 12. Further, the first rib 2 has a flat upper surface. The first rib 2 guides rainwater and mud flowing along the inner walls of the grill panel 10 and the grill base 20 to the second hole 12. Since the upper surface of the first rib 2 is flat, rainwater and mud can be easily guided into the second hole 12.

Note that the first rib 2 only needs to have a flat upper surface, and may have a downward slope, for example. The first rib 2 is provided with a downward slope by providing a draft during manufacturing of the grill panel 10. Since the first rib 2 is provided with a downward slope, rainwater and mud flowing out along the inner walls of the grill panel 10 and the grill base 20 can be easily guided to the second hole portion 12.

The length of the first rib 2 toward the rear of the vehicle may extend through the second hole 12 as shown in FIG. The length may extend to the front of the portion 12.

A lower portion of the grill base 20 is formed with unevenness 15 extending in the vehicle width direction. The unevenness 15 increases the rigidity of the lower part of the grill base 20, and the grill base 20 reinforces and supports the grill panel 10 from the rear side of the vehicle.

Further, as shown in FIGS. 2 and 3, a gap 13 is provided between the first rib 2 and the periphery of the second hole 12. As shown in FIGS. Rainwater and mud guided by the first rib 2 are discharged from this gap 13 to the rear side of the vehicle at the bottom of the grill base 20. The size of the gap 13 is not particularly limited.

As shown in FIGS. 2 and 3, the front grill 30 further includes a second rib 14 on the back surface of the grill base 20. The second rib 14 is provided below the portion of the grill base 20 where the second hole portion 12 is formed, and protrudes toward the rear of the vehicle. Further, the second rib 14 extends in the vehicle width direction, and is inclined downward in the vehicle direction as the distance from the second hole portion 12 increases.

The second rib 14 is provided below the second hole 12 to catch rainwater and mud discharged from the second hole 12 of the bulge 11 . In addition, the second rib 14 extends in the vehicle width direction and is inclined downwardly toward the vehicle as it becomes farther away from the second hole 12, so that rainwater and mud discharged from the second hole 12 can be absorbed by the second rib 14. flows out to the end portion 22 in the vehicle width direction along the slope. The vehicle widthwise end portions 22 are both ends of the rectangular capacitor opening 21 in the vehicle width direction (see FIG. 2).

As shown in FIGS. 1 and 2, an opening 24 is formed in the front grill 30. As shown in FIGS. The opening 24 is formed to penetrate the grill panel 10 and the grill base 20. Behind the opening 24, for example, a capacitor is provided on the left side in the vehicle width direction, and an engine intake port is provided on the right side in the vehicle width direction. Furthermore, a louver 23 is provided at the front of the intake port. The louver 23 is a part of the grill base 20, is provided in a rectangular intake opening 25 (see FIG. 1), and is exposed from the opening 24. A condenser opening 21 provided in the grill base 20 is provided in front of the condenser and communicates with the opening 24 as well as the intake opening 25 .

As shown in FIG. 3, the opening 24 of the front grill 30 forms a terminal end with the lower end of the grill panel 10 and the lower end of the grill base 20. When rainwater flows between the grill panel 10 and the unevenness 15 of the grill base 20, rainwater, mud, etc. may drip through the opening 24. In this case, rainwater, mud, etc. dripping from the opening 24 may adhere to the louver 23 and the grill panel 10 below the condenser opening 21, as shown in FIG.

In this embodiment, by providing the grill panel 10 with the first rib 2, rainwater is prevented from entering between the unevenness 15 of the grill panel 10 and the grill base 20. This prevents rainwater, mud, etc. from adhering to the grill panel 10 on the lower side of the section 24.

The capacitor opening 21 has a wide opening in the vehicle width direction, and is formed to have a larger dimension in the vehicle width direction than the second hole 12 . Further, the capacitor opening 21 is formed below the second hole 12 of the grill base 20. Further, the second rib 14 extends from the lower side of the second hole 12 to the end 22 of the capacitor opening 21 in the vehicle width direction.

As a result, rainwater and mud discharged from the second hole portion 12 flow out along the slope of the second rib 14 to the end portion 22 of the capacitor opening 21 in the vehicle width direction. In this way, the second rib 14 prevents rainwater and mud from adhering to the area around the louver 23 on the front side of the grill panel 10. In addition, the second rib 14 guides rainwater and mud to the end 22 in the vehicle width direction of the condenser opening 21 on the vehicle rear side (back side) of the grill base 20, so it is not visible to the public and is sloped. Rainwater and mud are flushed out along the vehicle width direction end portion 22. Note that the end portion in the vehicle width direction of the intake opening 25 (not shown) can have the same configuration as the end portion 22 in the vehicle width direction of the capacitor opening 21.

FIG. 4 is a partially enlarged view showing the back side of the grill panel 10. A plurality of first ribs 2 are formed on the grill panel 10. As shown in FIG. 4, the grill panel 10 is provided with two or more first ribs 2, and between adjacent first ribs 2, third ribs 4 that protrude rearward are formed. Moreover, the third rib 4 is formed so as to connect the adjacent first ribs 2. This makes it difficult for rainwater and mud to flow between the grill panel 10 below the third rib 4 and the unevenness 15 at the bottom of the grill base 20 (see FIGS. 2 and 3).

Further, the third rib 4 is formed to be shorter than the first rib 2 while extending toward the rear of the vehicle, and is formed so as not to come into contact with the grill base 20. The shape of the periphery of the bulge 11 changes by, for example, disposing a hook, a sensor, etc. (not shown) on the grill base 20. Therefore, the third rib 4 is made to follow the shape of the grill base 20 and close the space between the adjacent first ribs 2 by a predetermined length in the front and rear direction so that rainwater and mud do not fall on the lower part of the grill base 20. There is.

Moreover, the third rib 4 is formed between the adjacent first ribs 2, thereby increasing the rigidity of the grill panel 10. The third rib 4 dams up rainwater and mud by blocking the rainwater and mud from falling to the lower part of the grill base 20. The third rib 4 can drain the dammed rainwater and mud from the second hole 12 along the first rib 2. Moreover, the third rib 4 may be provided with a downward slope or a draft angle similarly to the first rib 2.

As described above, the front grill 30 according to the present embodiment is configured by combining the plate-shaped grill panel 10 and the grill base 20 arranged on the vehicle rear side of the grill panel 10.
A first hole 1 is formed in the grill panel 10, and a first rib 2 extending toward the rear of the vehicle is formed below the first hole 1. A first rib 2 is formed in the grill base 20. A second hole 12 is formed at a position facing the second hole 12 , and the first rib 2 extends toward the second hole 12 . A gap 13 is provided between.

According to this configuration, rainwater and mud that have passed through the first holes 1 flow out below the first holes 1 along the inner walls of the grill panel 10 and the grill base 20. Rainwater and mud flowing down the first hole 1 flow on the upper surface of the first rib 2 of the grill panel 10, are guided to the second hole 12, and are discharged from the gap 13. In this way, the first rib 2 can guide rainwater and mud flowing down the first hole 1 to the second hole 12. Moreover, the first rib 2 extends toward the second hole 12 to prevent rainwater and mud from flowing below the first rib 2. This makes it difficult for traces of dirty water to adhere to the surface of the front grill 30, making it possible to maintain the surface of the front grill in a clean state. Therefore, front grille 30 can suppress deterioration in appearance quality.

Further, the grill base 20 is formed with a bulge 11 that bulges toward the rear of the vehicle, and the second hole 12 is provided in the bulge 11 .

According to this configuration, rainwater and mud that have passed through the first hole 1 are discharged from the second hole 12 of the bulge 11 along the inner wall of the grill base 20. By providing the bulging portion 11, the front grill 30 can prevent jamming between the grill panel 10 and the grill base 20. Furthermore, the bulging portion 11 allows water to easily flow between the grill panel 10 and the grill base 20. Note that the bulging portion 11 is not an essential component but an optional component.

Further, a second rib 14 is formed below the location where the second hole portion 12 of the grill base 20 is formed, protruding toward the rear of the vehicle and slanting downward in the vehicle width direction.

According to this configuration, the front grill 30 has the second rib 14 formed on the grill base 20, thereby directing rainwater and mud discharged from the second holes 12 toward the vehicle width direction and toward the vehicle bottom. can lead. Thereby, rainwater and mud discharged from the second holes 12 can be prevented from accumulating in the grill base 20.

Further, a capacitor opening 21 having a larger dimension in the vehicle width direction than the second hole 12 is formed below the second hole 12 of the grill base 20, and the second rib 14 is connected to the second hole 12. It extends from the lower side to the end 22 in the vehicle width direction of the capacitor opening 21.

According to this configuration, the second rib 14 guides rainwater and mud discharged from the second hole portion 12 in the vehicle width direction and toward the vehicle width direction, and guides the rainwater and mud discharged from the second hole portion 12 to the vehicle width direction end portion of the capacitor opening portion 21. It flows out on the 22nd. Rainwater and mud that have flowed out to the end portion 22 in the vehicle width direction flow out below the end portion 22 in the vehicle width direction, so that they do not adhere to the grill panel 10. Thereby, the surface of the front grill 30 can be maintained in a clean state.

Further, the grill base 20 is provided with two or more first ribs 2, and between adjacent first ribs 2, a third rib 4 is formed that extends toward the rear of the vehicle. It has a shorter length in the longitudinal direction of the vehicle than the first rib 2, and does not come into contact with the grill base 20.

According to this configuration, rainwater and mud flowing down between the adjacent first ribs 2 are dammed up by the third ribs 4. The dammed rainwater and mud are then discharged from the second hole 12 via the first rib 2. Further, since the third rib 4 does not come into contact with the grill base 20, friction with the grill base 20 can be prevented. This prevents friction noise and distortion as well as damage.

Next, a modification of this embodiment will be described.
5 and 6 are explanatory diagrams showing a grill base without a bulge in a cross-sectional view taken along the line III--III in FIG. 1 as a modified example.
As shown in FIGS. 5 and 6, the front grills 31 and 32 each have a second hole 12 formed in the grill base 20 without the grill base 20 having the bulge 11. As shown in FIGS.

Even with such a configuration, the second hole portion 12 can discharge rainwater and mud guided by the first rib 2 from the second hole portion 12 . Therefore, even with the grill base 20 that does not have the bulging portion 11 like the front grills 31 and 32, the same effects as in this embodiment can be obtained.
