- FIG. 1 is a front view of a vehicle 100 equipped with a radiator grille (vehicle grille) according to this embodiment.
- the radiator grille 1 according to this embodiment is a front grille installed at the front of the vehicle 100, and is disposed in front of a radiator disposed inside an engine compartment.
- This radiator grille 1 is an exterior component formed mainly from resin.
- the vehicle 100 has two headlights 101 (first exterior part) arranged at a distance in the vehicle width direction (horizontal direction).
- the headlights 101 are lighting devices that illuminate the area ahead of the vehicle, and are exterior parts that are visible from outside the vehicle 100 and form the external appearance of the vehicle 100.
- the vehicle 100 also has an upper garnish 102 (second exterior part) located above the headlights 101.
- the upper garnish 102 is a plate-shaped exterior part whose longitudinal direction is the vehicle width direction. One longitudinal end of the upper garnish 102 is located above one of the two headlights 101, and the other longitudinal end is located above the other of the two headlights 101.
- the headlights 101 are fixed to, for example, the vehicle frame, and are not directly supported by the radiator grille 1.
- the upper garnish 102 is directly supported by the radiator grille 1, which is fixed to the bumper or the vehicle frame.
- the radiator grille 1 supports the upper garnish 102, which is a second exterior part located above the headlights 101, which is a first exterior part.
- the upper garnish 102 has a central part in the vehicle width direction connected to the radiator grille 1, and both ends in the vehicle width direction protrude outward in the vehicle width direction beyond the radiator grille 1.
- FIG. 2 is a front view showing the schematic configuration of the radiator grill 1 of this embodiment.
- FIG. 3 is a rear view showing the schematic configuration of the radiator grill 1 of this embodiment.
- FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 3.
- the radiator grille 1 of this embodiment comprises a grille body 2, a first decorative part 3, and a second decorative part 4.
- the grille body 2 is fixed to, for example, the bumper or body frame of the vehicle 100, and supports the first decorative part 3 and the second decorative part 4.
- the grille body 2 also supports the above-mentioned upper garnish 102 from below.
- the grill body 2 comprises an upper part 5, a lower part 6, and screws 7.
- Figure 5 is a schematic exploded view of the upper part 5 and the lower part 6 as viewed from the rear.
- the radiator grill 1 of this embodiment is formed by dividing it into the upper part 5 and the lower part 6.
- the upper part 5 and the lower part 6 are depicted spaced apart in the vertical direction.
- the upper part 5 is a resin part that forms the upper part of the grill body 2. At least a part of the upper part 5 is located above the lower part 6.
- the upper part 5 has a front part 5a and an upper wall part 5b, as shown in Figs. 4 and 5, for example.
- the front part 5a is a part that is fixed to the lower part 6.
- the front part 5a has a first part that extends in the vertical direction at a position above the lower part 6, a second part that extends rearward from the lower end of the first part, and a third part that extends downward from the rear end of the second part, and is formed in a crank shape when viewed in the width direction.
- Fig. 6 is a cross-sectional view taken along line VI-VI in Fig. 5 when the upper part 5 and the lower part 6 are fixed.
- the front portion 5a of the upper part 5 is located above the lower part 6 and has a wall surface 5a1 facing downward.
- the wall surface 5a1 corresponds to the lower surface of the second part.
- the wall surface 5a1 is provided with a height regulating protrusion 5c that protrudes downward.
- the upper part 5 has a height regulating protrusion 5c that protrudes downward.
- the height regulating protrusion 5c corresponds to a height regulating portion 10 that regulates the vertical position of the upper part 5 relative to the lower part 6.
- the height regulating portion 10 in this embodiment is provided with a height regulating protrusion 5c.
- the height-regulating protrusion 5c is a protrusion that abuts against the lower part 6 from above. In other words, the lower end of the height-regulating protrusion 5c abuts against the lower part 6 from above.
- This height-regulating protrusion 5c regulates the positional relationship between the upper part 5 and the lower part 6 in the vertical direction. For example, when the height-regulating protrusion 5c protrudes a large amount from the wall surface 5a1, the upper part 5 and the lower part 6 are positioned farther apart in the vertical direction than when the protrusion amount is small.
- multiple height regulating protrusions 5c are arranged in the width direction of the vehicle 100 (the vehicle width direction when the radiator grille 1 is attached to the vehicle 100).
- the height regulating protrusions 5c may be paired in pairs of two that are arranged close to each other, with multiple pairs provided along the vehicle width direction.
- each height-regulating protrusion 5c is provided extending linearly along the fore-and-aft direction of the vehicle 100 (the fore-and-aft direction of the vehicle when the radiator grille 1 is attached to the vehicle 100). This allows each height-regulating protrusion 5c to come into contact with the lower part 6 over a wide range in the fore-and-aft direction of the vehicle. This makes it possible to prevent the upper part 5 from tilting relative to the lower part 6 when viewed from the direction along the vehicle width direction.
- the upper wall portion 5b is formed to protrude rearward from the upper end of the front portion 5a, and is a plate-shaped portion to which the upper garnish 102 is fixed. That is, the upper wall portion 5b extends rearward from the upper end of the first portion of the front portion 5a.
- the upper wall portion 5b supports the upper garnish 102 from below. Since the upper garnish 102 is fixed to the upper wall portion 5b of the upper part 5 in this manner, it is also moved upward when the upper part 5 is moved upward. In other words, the greater the protrusion amount of the height-regulating protrusion 5c, the higher the position of the upper part 5, and therefore the upper garnish 102 is also positioned upward. Also, the smaller the protrusion amount of the height-regulating protrusion 5c, the lower the position of the upper part 5, and therefore the upper garnish 102 is also positioned downward.
- the headlights 101 are not directly connected to the radiator grille 1. Therefore, the greater the amount of protrusion of the height-regulating protrusion 5c, the more the upper garnish 102 supported by the radiator grille 1 is moved upward and away from the headlights 101. Also, the smaller the amount of protrusion of the height-regulating protrusion 5c, the more the upper garnish 102 supported by the radiator grille 1 is moved downward and closer to the headlights 101.
- a temporary holding opening 5a2 (retained portion) is provided in the front portion 5a of the upper part 5.
- two temporary holding openings 5a2 are provided in the upper part 5.
- Each temporary holding opening 5a2 is formed penetrating in the fore-and-aft direction of the vehicle 100, and a protrusion 6b1 of a temporary holding claw portion 6b (described later) of the lower part 6 is inserted into it.
- the number of temporary holding openings 5a2 and temporary holding claw portions 6b is not limited to two, and three or more may be provided.
- the front portion 5a of the upper part 5 is provided with a number of screw insertion holes 5d. These screw insertion holes 5d are holes through which screws 7 are inserted to fasten the upper part 5 and the lower part 6 together.
- the lower part 6 is a resin part that forms the lower part of the grill body 2.
- the lower part 6 is fixed to an external part 103 (a part that is provided on the vehicle 100 and is different from the radiator grill 1) such as a bumper or a body frame.
- the lower part 6 has a base 6a, a temporary holding claw part 6b, a support wall 6c, and a protruding wall 6d.
- the base 6a is the main structural part of the radiator grille 1 and has multiple openings 6a1 that penetrate in the front-rear direction.
- each opening 6a1 is formed in a rectangular shape with the vehicle width direction as the longitudinal direction.
- the multiple openings 6a1 are arranged in the vertical direction.
- Such a base 6a has multiple horizontal bar portions 6a2 provided between the openings 6a1.
- the shape of each opening 6a1 is not particularly limited. Also, for example, in an electric vehicle or the like that does not have an internal combustion engine, it is possible to adopt a configuration that does not have openings 6a1.
- Each horizontal bar portion 6a2 is provided with a plurality of mounting portions 6a3 for mounting the second decorative part 4.
- the upper edge portion 6a4 of the base portion 6a is the portion where the upper part 5 is mounted.
- This upper edge portion 6a4 is provided with claw openings 6a5 in accordance with the installation positions of each temporary holding claw portion 6b.
- These claw openings 6a5 are provided penetrating the base portion 6a in the fore-and-aft direction of the vehicle 100. By providing such claw openings 6a5, the temporary holding claw portions 6b can elastically deform in the fore-and-aft direction of the vehicle 100.
- the upper edge 6a4 of the base 6a is provided with a plurality of female threaded portions 6a6 into which the screws 7 are screwed.
- Each female threaded portion 6a6 is positioned so as to overlap with a screw insertion hole 5d of the upper part 5 when the upper part 5 is attached to the lower part 6.
- the lower part 6 and the upper part 5 are fastened together by screwing the screw 7 inserted into the screw insertion hole 5d into each female threaded portion 6a6.
- the upper edge 6a4 of the base 6a is also provided with a plurality of mounting portions 6a7 for mounting the first decorative part 3.
- Such a base 6a is fixed to an external part 103 such as a bumper or a vehicle frame via an attachment part (not shown).
- the lower part 6 is fixed to an external part 103 such as a bumper or a vehicle frame.
- each temporary retaining claw portion 6b is arranged to hang down from the upper edge (i.e., the inner surface facing downward) of each claw opening 6a5 of the base 6a.
- two temporary retaining claw portions 6b are also provided.
- Figure 7 is a cross-sectional view taken along line VII-VII in Figure 5 when the upper part 5 and the lower part 6 are fixed.
- each temporary retaining claw portion 6b is formed with a thickness dimension that allows it to bend and deform in the fore-and-aft direction of the vehicle 100.
- each temporary retaining claw portion 6b has a protrusion 6b1 that protrudes toward the rear of the vehicle 100.
- each temporary holding claw portion 6b When the upper part 5 is attached to the lower part 6, the protrusion 6b1 of each temporary holding claw portion 6b comes into contact with the upper part 5 moving downward, and the temporary holding claw portion 6b is elastically deformed toward the front side of the vehicle 100. Thereafter, when the temporary holding opening 5a2 provided in the upper part 5 reaches the protrusion 6b1, each temporary holding claw portion 6b restores its original shape. As a result, the protrusion 6b1 of the temporary holding claw portion 6b enters the temporary holding opening 5a2. The protrusion 6b1 of the temporary holding claw portion 6b enters the temporary holding opening 5a2, preventing the upper part 5 from being pulled out upward from the lower part 6.
- the vertical size of the temporary holding opening 5a2 is greater than the vertical width of the protrusion 6b1. Therefore, even when the protrusion 6b1 is inserted into the temporary holding opening 5a2, the upper part 5 can move slightly vertically relative to the lower part 6. Therefore, the protrusion 6b1 does not prevent the adjustment of the vertical position of the upper part 5 using the height-regulating protrusion 5c.
- FIG. 8 is a cross-sectional view taken along line VIII-VIII in FIG. 5 when the upper part 5 and the lower part 6 are fixed.
- the support wall 6c is connected to a portion of the base 6a located below the claw opening 6a5.
- the support wall 6c protrudes from the base 6a toward the rear of the vehicle 100, and is then bent upward.
- Such a support wall 6c has a vertical wall portion 6c1 parallel to the rear surface of the base 6a. That is, the support wall 6c has a front-rear extending portion 6c2 extending rearward from the base 6a, and a vertical wall portion 6c1 extending upward from the rear end of the front-rear extending portion 6c2.
- the vertical wall portion 6c1 is disposed rearward and spaced apart from the base 6a when viewed in the vehicle width direction.
- the distance between the rear surface of the base 6a and the front surface of the vertical wall portion 6c1 is set to a dimension that allows the lower edge portion of the front portion 5a of the upper part 5 (i.e., the third portion) to be inserted. Therefore, the lower edge of the upper part 5 can be inserted between the base 6a and the standing wall 6c1.
- the base 6a is located in front of the lower edge of the upper part 5, and the standing wall 6c1 is located behind the lower edge.
- the movement of the upper part 5 in the fore-and-aft direction of the vehicle 100 is restricted.
- the upper part 5 attached to the lower part 6 is sandwiched between the base 6a and the standing wall 6c1, thereby restricting the movement of the vehicle 100 in the fore-and-aft direction.
- the protruding wall 6d is a wall that protrudes upward from the lower edge of the claw opening 6a5 (i.e., the inner surface facing upward). This protruding wall 6d is located in front of the lower edge of the upper part 5, which is located between the base 6a and the standing wall 6c1. By providing such a protruding wall 6d, the forward movement of the upper part 5 attached to the lower part 6 is restricted not only by the base 6a but also by the protruding wall 6d. Therefore, the movement of the upper part 5 attached to the lower part 6 in the fore-and-aft direction of the vehicle 100 can be more reliably restricted.
- Each screw 7 is inserted into a screw insertion hole 5d provided in the upper part 5 and is screwed into the female threaded portion 6a6 of the lower part 6.
- the upper part 5 and the lower part 6 are fastened together by these screws 7 as described above.
- the fastening structure of the upper part 5 and the lower part 6 is not limited to the screw 7 screwed into the female threaded portion 6a6, but may be a fastening structure using a bolt and a nut, or a pin member having an elastically deformable locking claw.
- the vertical size of the screw insertion hole 5d in this embodiment is larger than the outer diameter of the screw 7, even if the screw 7 is inserted into the screw insertion hole 5d, the upper part 5 has a vertical movement margin relative to the lower part 6. Therefore, even after the vertical position of the upper part 5 is adjusted using the height regulation protrusion 5c, the screw 7 can be properly screwed into the female threaded portion 6a6.
- the first decorative part 3 is a resin part that covers the connection between the upper part 5 and the lower part 6 from the front of the vehicle. As shown in FIG. 4, the first decorative part 3 has a locking claw 3a that protrudes toward the rear. There are multiple locking claws 3a. Each locking claw 3a is inserted into an attachment portion 6a7 provided on the lower part 6, and thereby locked to the lower part 6. The first decorative part 3 is fixed to the lower part 6 by locking these locking claws 3a to the lower part 6.
- the second decorative part 4 is a resin part that is placed in front of the horizontal bar portion 6a2 of the lower part 6. As shown in FIG. 4, multiple second decorative parts 4 are provided for each horizontal bar portion 6a2. Each second decorative part 4 has a locking claw 4a that protrudes rearward. Multiple locking claws 4a are provided for each second decorative part 4. Each locking claw 4a is inserted into an attachment portion 6a3 provided on the lower part 6, and thereby locked to the lower part 6. The second decorative part 4 is fixed to the lower part 6 by locking these locking claws 4a to the lower part 6.
- the upper part 5 is attached to the lower part 6.
- the lower edge of the front part 5a of the upper part 5 is inserted between the base part 6a of the lower part 6 and the vertical wall part 6c1 of the support wall 6c.
- the upper part 5 is moved downward relative to the lower part 6.
- the protrusion 6b1 of the temporary holding claw portion 6b of the lower part 6 fits into the temporary holding opening 5a2 provided in the front portion 5a of the upper part 5. This prevents the upper part 5 from slipping out of the lower part 6 in the vertical and width directions.
- the front portion 5a of the upper part 5 is sandwiched between the base portion 6a of the lower part 6 and the vertical wall portion 6c1 of the support wall 6c, movement of the upper part 5 in the front-to-rear direction relative to the lower part 6 is restricted. Therefore, even before fastening with the screws 7, the upper part 5 is temporarily held by the lower part 6.
- the height-direction position of the upper part 5 relative to the lower part 6 is determined by the height-regulating protrusion 5c provided on the upper part 5 abutting against the upper end of the base 6a of the lower part 6.
- the amount of protrusion of the height-regulating protrusion 5c is set in advance so that the upper garnish 102 does not interfere with the headlight 101. Therefore, by the height-regulating protrusion 5c abutting against the upper end of the base 6a of the lower part 6, the height-direction position of the upper part 5 is determined at a position where the upper garnish 102 does not interfere with the headlight 101.
- the upper part 5 and the lower part 6 are fastened together with the screws 7. Furthermore, the first decorative part 3 is attached to the lower part 6. Furthermore, the second decorative part 4 is attached to the lower part 6. Note that the timing of attaching the first decorative part 3 and the second decorative part 4 can be changed.
- the method for designing the radiator grille 1 described below is a method for designing a radiator grille 1 that supports a second exterior part (upper garnish 102) that is located above a first exterior part (headlight 101).
- the shapes of the upper part 5 and the lower part 6 are provisionally determined (provisional shape determination step S1).
- the amount of protrusion of the height regulating protrusion 5c provided on the upper part 5 is provisionally determined.
- the amount of protrusion of the height regulating protrusion 5c here to an amount that can be decreased later.
- positional relationship confirmation process S2 the positional relationship between the headlight 101 and the upper garnish 102 is confirmed using the upper part 5 and lower part 6 whose shapes have been provisionally determined in the shape provisional determination process S1.
- positional relationship confirmation process S2 the positional relationship between the headlight 101 and the upper garnish 102 may be confirmed by simulation. However, it is better to confirm the positional relationship between the headlight 101 and the upper garnish 102 by actually creating and assembling the actual parts.
- the amount of protrusion of the height-regulating protrusion 5c is adjusted (height adjustment process S3).
- the amount of protrusion of the height-regulating protrusion 5c is adjusted based on the confirmation result of the positional relationship confirmation process S2. For example, if the confirmation result obtained in the positional relationship confirmation process S2 is that the upper garnish 102 will interfere with the headlight 101, the amount of protrusion of the height-regulating protrusion 5c is increased. By increasing the amount of protrusion of the height-regulating protrusion 5c, the position of the upper part 5 is raised, and at the same time, the position of the upper garnish 102 can be raised. Therefore, interference between the upper garnish 102 and the headlight 101 can be avoided.
- the upper part 5 is formed by injection molding of resin. Therefore, the amount of protrusion of the height-regulating protrusion 5c can be adjusted by adjusting the shape of the mold used during injection molding. For example, if the amount of protrusion of the height-regulating protrusion 5c needs to be increased, the amount of protrusion of the height-regulating protrusion 5c can be easily increased by removing part of the mold.
- the amount of protrusion of the height-regulating protrusion 5c is reduced.
- the position of the upper part 5 is lowered, and at the same time, the position of the upper garnish 102 can be lowered. Therefore, the gap between the upper garnish 102 and the headlight 101 can be reduced.
- the shapes of the lower part 6 and the upper part 5 are determined (determination step S4).
- the shapes of the lower part 6 and the upper part 5 are determined so as to include the height-regulating protrusion 5c whose protrusion amount has been adjusted in the height adjustment step S3.
- the shape of the upper part 5 is determined based on the protrusion amount of the height-regulating protrusion 5c adjusted in the height adjustment step S3. Note that if there is no room to increase or decrease the protrusion amount of the height-regulating protrusion 5c, the shape of the lower part 6 may be changed to determine the height position of the upper part 5.
- the shapes of the first decorative part 3 and the second decorative part 4 can be determined, for example, separately from the process shown in FIG. 9. Therefore, the shapes of the first decorative part 3 and the second decorative part 4 can be determined after the shapes of the lower part 6 and the upper part 5 are determined. Also, the shapes of the first decorative part 3 and the second decorative part 4 may be determined before the shapes of the lower part 6 and the upper part 5 are determined. Furthermore, the shapes of the first decorative part 3 and the second decorative part 4 may be determined in parallel with the shapes of the lower part 6 and the upper part 5.
- radiator grill 1 designed using the design method of the radiator grill 1 of this embodiment, it is possible to mass-produce radiator grills 1 that can appropriately adjust the positional relationship between the upper garnish 102 and the headlights 101.
- the radiator grill 1 of this embodiment supports the upper garnish 102 located above the headlight 101.
- the radiator grill 1 of this embodiment also includes a lower part 6 and an upper part 5.
- the lower part 6 is fixed to an external part 103.
- the upper part 5 has the upper garnish 102 fixed thereto, and is located above the lower part 6 and fastened to the lower part 6.
- the radiator grill 1 of this embodiment also has a height-regulating protrusion 5c that is provided on the upper part 5, which is one of the lower part 6 and upper part 5, and abuts the lower part 6, which is the other, from above.
- the radiator grille 1 is divided into an upper part 5 and a lower part 6. Furthermore, by adjusting the height dimension of the height-regulating protrusion 5c, the heightwise position of the upper part 5 relative to the lower part 6 can be changed. Therefore, for example, if it becomes necessary to correct the positional relationship of the upper garnish 102 relative to the headlight 101, the heightwise position of the upper garnish 102 relative to the headlight 101 can be adjusted by adjusting only the height dimension (i.e., the amount of protrusion) of the height-regulating protrusion 5c, without having to reconsider the overall shape of the radiator grille 1. Therefore, according to the radiator grille 1 of this embodiment, the heightwise position of the upper garnish 102 can be easily adjusted.
- radiator grille 1 of this embodiment multiple height-regulating protrusions 5c are provided and arranged in the width direction of the vehicle 100. Therefore, in the radiator grille 1 of this embodiment, the upper part 5 and the lower part 6 abut at multiple points in the vehicle width direction, and it is possible to prevent the upper part 5 from tilting relative to the lower part 6 when viewed from the front of the vehicle 100.
- the height-regulating protrusion 5c is provided extending linearly in the fore-and-aft direction of the vehicle 100. This allows the height-regulating protrusion 5c to come into contact with the lower part 6 over a wide range in the fore-and-aft direction of the vehicle. Therefore, the radiator grille 1 of this embodiment can prevent the upper part 5 from tilting relative to the lower part 6 when viewed from the direction along the vehicle width direction.
- the radiator grille 1 of this embodiment also includes a temporary retaining claw portion 6b provided on the lower part 6, which is one of the lower part 6 and the upper part 5.
- the radiator grille 1 of this embodiment also includes a temporary retaining opening 5a2 provided on the upper part 5, which is the other of the lower part 6 and the upper part 5, and capable of engaging the temporary retaining claw portion 6b.
- the upper part 5 can be temporarily held relative to the lower part 6 before the lower part 6 and the upper part 5 are fastened together during assembly. This allows the lower part 6 and the upper part 5 to be fastened together with the positional relationship between them being stable.
- the radiator grille 1 of this embodiment also includes multiple decorative parts (first decorative part 3 and second decorative part 4) that are visible from the outside. These first decorative part 3 and second decorative part 4 are attached to the lower part 6. In other words, in the radiator grille 1 of this embodiment, all decorative parts are attached to the lower part 6. This prevents the weight of the decorative parts from being placed on the upper part 5, and by attaching the decorative parts, it is possible to prevent the position of the upper garnish 102 from changing.
- the design method for the radiator grille 1 of this embodiment is a design method for the radiator grille 1 that supports the upper garnish 102 located above the headlight 101.
- the design method for the radiator grille 1 of this embodiment includes a shape tentative determination process S1, a positional relationship confirmation process S2, a height adjustment process S3, and a determination process S4.
- the provisional shape determination process S1 is a process for provisionally determining the shape of the lower part 6 and the upper part 5.
- the positional relationship confirmation process S2 is a process for confirming the positional relationship between the headlight 101 and the upper garnish 102 in the shape provisionally determined in the provisional shape determination process S1.
- the height adjustment process S3 is a process for adjusting the protrusion amount of the height-regulating protrusion 5c based on the confirmation result of the positional relationship confirmation process S2.
- the determination process S4 is a process for determining the shape of the lower part 6 and the upper part 5, including the height-regulating protrusion 5c whose protrusion amount has been adjusted in the height adjustment process S3.
- the height dimension (i.e., the amount of protrusion) of the height-regulating protrusion 5c alone can be adjusted to adjust the height direction position of the upper garnish 102 relative to the headlight 101 without reconsidering the overall shape of the radiator grille 1. Therefore, according to the design method of the radiator grille 1 of this embodiment, the positional relationship between the upper garnish 102 and the headlight 101 can be appropriately set.

- the first through holes 8 and the second through holes 9 correspond to each other. That is, the first through hole 8a and the second through hole 9a correspond to each other, the first through hole 8b and the second through hole 9b correspond to each other, the first through hole 8c and the second through hole 9c correspond to each other, and the first through hole 8d and the second through hole 9d correspond to each other.
- “Corresponding" means that the pin member 11 can be inserted into the corresponding first through hole 8 and second through hole 9.
- a pin member 11 is inserted and engaged into the first through hole 8c and the second through hole 9c.
- the pin member 11 has a shaft portion 11a extending in the front-to-rear direction, a head portion 11b provided at the front end of the shaft portion 11a, and two engagement claws 11c provided at the rear end of the shaft portion 11a and whose spacing can be elastically changed.

- the multiple first through holes 8 formed in the upper part 5 are arranged in a direction slightly inclined from the width direction (i.e., the horizontal direction). That is, the first through hole 8a is located above the first through hole 8b in the vertical direction, the first through hole 8b is located above the first through hole 8c in the vertical direction, and the first through hole 8c is located above the first through hole 8d in the vertical direction. In this embodiment, among the multiple first through holes 8, two adjacent first through holes 8 are arranged at a certain distance in the vertical direction.
- the vertical distance h1 between the first through hole 8a and the first through hole 8b, the vertical distance h2 between the first through hole 8b and the first through hole 8c, and the vertical distance h3 between the first through hole 8c and the first through hole 8d are equal to each other.
- the values of the distances h1, h2, and h3 are, for example, 0.5 mm, but may be other values. In this embodiment, the values of distances h1, h2, and h3 are equal, but may be different from each other.
- the second through holes 9 formed in the lower part 6 are arranged in the width direction (i.e., horizontal direction).

Description
本発明は、車両用グリル及び車両用グリルの設計方法に関する。
本願は、2022年10月26日に日本に出願された特願2022-171323号に基づき優先権を主張し、その内容をここに援用する。 The present invention relates to a vehicle grille and a method for designing a vehicle grille.
This application claims priority based on Japanese Patent Application No. 2022-171323, filed in Japan on October 26, 2022, the contents of which are incorporated herein by reference.
本願は、2022年10月26日に日本に出願された特願2022-171323号に基づき優先権を主張し、その内容をここに援用する。 The present invention relates to a vehicle grille and a method for designing a vehicle grille.
This application claims priority based on Japanese Patent Application No. 2022-171323, filed in Japan on October 26, 2022, the contents of which are incorporated herein by reference.
例えば、特許文献1には、車両用フロントグリルを備える車両が開示されている。特許文献1に示すように、車両用フロントグリルは、車両の前部に配置されている。また、このような車両用フロントグリルは、一般的に、車両の前部に2つ配置されるヘッドライトの間に位置する。
For example, Patent Document 1 discloses a vehicle equipped with a vehicle front grille. As shown in Patent Document 1, the vehicle front grille is disposed at the front of the vehicle. Furthermore, such a vehicle front grille is generally positioned between two headlights disposed at the front of the vehicle.
ところで、特許文献1に開示された車両用フロントグリル等の車両用グリルは、車両の外部から視認可能な外装部品である。このような車両用グリルは、他の外装部品を支持する支持体として用いられる場合もある。例えば、2つのヘッドライトの間に配置される車両用グリルは、2つのヘッドライトの上方に位置するアッパーガーニッシュを支持する支持体として用いられる場合がある。しかしながら、車両用グリル自体の変形や、車両用グリルを支持する車両部品の変形により、組み立て後のアッパーガーニッシュが本来の設置位置よりも僅かに下方にずれる場合がある。このような場合には、アッパーガーニッシュがヘッドライトと干渉してしまうことがある。つまり、車両用グリルが、第1外装部品の上方に位置する第2外装部品を支持する場合に、第2外装部品が第1外装部品と干渉する場合がある。このように第1外装部品と第2外装部品とが干渉する場合には、車両用グリルの全体形状を設計し直す必要が生じ、必要に応じて金型を作り直す等の大規模な対策を要する。
However, a vehicle grille such as the vehicle front grille disclosed in Patent Document 1 is an exterior part that can be seen from outside the vehicle. Such a vehicle grille may be used as a support for supporting other exterior parts. For example, a vehicle grille disposed between two headlights may be used as a support for supporting an upper garnish located above the two headlights. However, due to deformation of the vehicle grille itself or deformation of the vehicle parts supporting the vehicle grille, the upper garnish after assembly may be shifted slightly downward from its original installation position. In such a case, the upper garnish may interfere with the headlight. In other words, when the vehicle grille supports a second exterior part located above a first exterior part, the second exterior part may interfere with the first exterior part. In such a case where the first exterior part and the second exterior part interfere with each other, it becomes necessary to redesign the overall shape of the vehicle grille, and large-scale measures such as remaking a mold are required as necessary.
本発明は、上述する問題点に鑑みてなされたもので、第1外装部品の上方に位置する第2外装部品を支持する車両用グリルにおいて、第2外装部品の高さ方向の位置を容易に調整可能とすることを目的とする。

本発明の第10の態様は、前記第9の態様において、前記高さ規定部が、前記下方パーツと前記上方パーツの一方に設けられると共に他方に上下方向から当接する高さ規定突部を備え、前記高さ調整工程では、前記高さ規定突部の上下方向の突出量を調整し、前記決定工程では、前記高さ調整工程で突出量が調整された前記高さ規定突部を含んで前記下方パーツと前記上方パーツの形状を決定する。

本発明によれば、車両用グリルが上方パーツと下方パーツとに分割形成されている。さらに高さ規定部によって、下方パーツに対する上方パーツの高さ方向の位置を変更することができる。したがって、例えば、第2外装部品の第1外装部品に対する位置関係を修正する必要が生じた場合には、高さ規定部によって下方パーツに対する上方パーツの高さ方向の位置を調整することで、車両用グリルの全体形状を見直すことなく、第2外装部品の第1外装部品に対する高さ方向の位置調整を行うことができる。よって、本発明によれば、第1外装部品の上方に位置する第2外装部品を支持する車両用グリルにおいて、第2外装部品の高さ方向の位置を容易に調整することができる。
According to the present invention, the vehicle grille is divided into an upper part and a lower part. Furthermore, the height-direction position of the upper part relative to the lower part can be changed by the height-regulating unit. Therefore, for example, if it becomes necessary to correct the positional relationship of the second exterior part relative to the first exterior part, the height-direction position of the second exterior part relative to the first exterior part can be adjusted by adjusting the height-direction position of the upper part relative to the lower part by the height-regulating unit, without having to reconsider the overall shape of the vehicle grille. Therefore, according to the present invention, in a vehicle grille that supports the second exterior part located above the first exterior part, the height-direction position of the second exterior part can be easily adjusted.

本発明の第1実施形態について以下に説明する。
図1は、本実施形態のラジエータグリル(車両用グリル)を備える車両100の正面図である。本実施形態のラジエータグリル1は、車両100の前部に設置されたフロントグリルであり、エンジンルームの内部に配置されたラジエータの前方に配置されている。このラジエータグリル1は、主として樹脂によって形成された外装部品である。 A first embodiment of the present invention will be described below.
1 is a front view of avehicle 100 equipped with a radiator grille (vehicle grille) according to this embodiment. The radiator grille 1 according to this embodiment is a front grille installed at the front of the vehicle 100, and is disposed in front of a radiator disposed inside an engine compartment. This radiator grille 1 is an exterior component formed mainly from resin.
図1は、本実施形態のラジエータグリル(車両用グリル)を備える車両100の正面図である。本実施形態のラジエータグリル1は、車両100の前部に設置されたフロントグリルであり、エンジンルームの内部に配置されたラジエータの前方に配置されている。このラジエータグリル1は、主として樹脂によって形成された外装部品である。 A first embodiment of the present invention will be described below.
1 is a front view of a
図1に示すように、車両100は、車幅方向(水平方向)に離れて配列された2つのヘッドライト101(第1外装部品)を有している。ヘッドライト101は、車両の前方を照らす照明装置であると共に、車両100の外部から視認されて車両100の外観を形成する外装部品である。また、車両100は、ヘッドライト101の上方に位置するアッパーガーニッシュ102(第2外装部品)を備える。アッパーガーニッシュ102は、車幅方向を長手方向とする板状の外装部品である。アッパーガーニッシュ102は、長手方向の一端部が2つのヘッドライト101の一方の上方に位置し、長手方向の他端部が2つのヘッドライト101の他方の上方に位置する。
As shown in FIG. 1, the vehicle 100 has two headlights 101 (first exterior part) arranged at a distance in the vehicle width direction (horizontal direction). The headlights 101 are lighting devices that illuminate the area ahead of the vehicle, and are exterior parts that are visible from outside the vehicle 100 and form the external appearance of the vehicle 100. The vehicle 100 also has an upper garnish 102 (second exterior part) located above the headlights 101. The upper garnish 102 is a plate-shaped exterior part whose longitudinal direction is the vehicle width direction. One longitudinal end of the upper garnish 102 is located above one of the two headlights 101, and the other longitudinal end is located above the other of the two headlights 101.
ヘッドライト101は、例えば、車体フレームに対して固定されており、ラジエータグリル1によって直接的に支持されていない。一方で、アッパーガーニッシュ102は、バンパや車体フレームに固定されたラジエータグリル1によって直接的に支持されている。つまり、本実施形態において、ラジエータグリル1は、第1外装部品であるヘッドライト101の上方に位置する第2外装部品であるアッパーガーニッシュ102を支持している。アッパーガーニッシュ102は、車幅方向の中央部がラジエータグリル1に接続されており、車幅方向の両端部がラジエータグリル1よりも車幅方向の外側に突出している。
The headlights 101 are fixed to, for example, the vehicle frame, and are not directly supported by the radiator grille 1. On the other hand, the upper garnish 102 is directly supported by the radiator grille 1, which is fixed to the bumper or the vehicle frame. In other words, in this embodiment, the radiator grille 1 supports the upper garnish 102, which is a second exterior part located above the headlights 101, which is a first exterior part. The upper garnish 102 has a central part in the vehicle width direction connected to the radiator grille 1, and both ends in the vehicle width direction protrude outward in the vehicle width direction beyond the radiator grille 1.
図2は、本実施形態のラジエータグリル1の概略構成を示す正面図である。また、図3は、本実施形態のラジエータグリル1の概略構成を示す背面図である。また、図4は、図3のIV-IV線視断面図である。
FIG. 2 is a front view showing the schematic configuration of the radiator grill 1 of this embodiment. FIG. 3 is a rear view showing the schematic configuration of the radiator grill 1 of this embodiment. FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 3.
図2~4に示すように、本実施形態のラジエータグリル1は、グリル本体部2と、第1加飾用パーツ3と、第2加飾用パーツ4とを備えている。グリル本体部2は、例えば車両100のバンパや車体フレームに対して固定されると共に、第1加飾用パーツ3及び第2加飾用パーツ4を支持する。また、グリル本体部2は、上述のアッパーガーニッシュ102を下方から支持する。
As shown in Figures 2 to 4, the radiator grille 1 of this embodiment comprises a grille body 2, a first decorative part 3, and a second decorative part 4. The grille body 2 is fixed to, for example, the bumper or body frame of the vehicle 100, and supports the first decorative part 3 and the second decorative part 4. The grille body 2 also supports the above-mentioned upper garnish 102 from below.
例えば、図2~4に示すように、グリル本体部2は、上方パーツ5と、下方パーツ6と、ネジ7とを備える。図5は、上方パーツ5と下方パーツ6とを後方から見た模式的な分解図である。図5に示すように、本実施形態のラジエータグリル1は、上方パーツ5と、下方パーツ6とに分割形成されている。図5において、上方パーツ5と下方パーツ6は、上下方向に離間して記載されている。
For example, as shown in Figures 2 to 4, the grill body 2 comprises an upper part 5, a lower part 6, and screws 7. Figure 5 is a schematic exploded view of the upper part 5 and the lower part 6 as viewed from the rear. As shown in Figure 5, the radiator grill 1 of this embodiment is formed by dividing it into the upper part 5 and the lower part 6. In Figure 5, the upper part 5 and the lower part 6 are depicted spaced apart in the vertical direction.
上方パーツ5は、グリル本体部2の上部を形成する樹脂パーツである。上方パーツ5の少なくとも一部が、下方パーツ6の上方に位置している。上方パーツ5は、例えば図4、5に示すように、前部5aと、上壁部5bとを有する。前部5aは、下方パーツ6に固定される部位である。本実施形態の前部5aは、下方パーツ6よりも上方の位置で上下方向に延びる第1部分と、当該第1部分の下端から後方に延びる第2部分と、当該第2部分の後端から下方に延びる第3部分とを備えており、幅方向に見た際にクランク状に形成されている。なお、前部5aはこのような形状に限定されず、下方を向きかつ下方パーツ6の上方に位置する面(本実施形態では前記第2部分の下面に相当する)を有していれば、どのような形状であってもよい。図6は、上方パーツ5と下方パーツ6が固定された状態における図5のVI-VI線視断面図である。
The upper part 5 is a resin part that forms the upper part of the grill body 2. At least a part of the upper part 5 is located above the lower part 6. The upper part 5 has a front part 5a and an upper wall part 5b, as shown in Figs. 4 and 5, for example. The front part 5a is a part that is fixed to the lower part 6. In this embodiment, the front part 5a has a first part that extends in the vertical direction at a position above the lower part 6, a second part that extends rearward from the lower end of the first part, and a third part that extends downward from the rear end of the second part, and is formed in a crank shape when viewed in the width direction. Note that the front part 5a is not limited to this shape, and may have any shape as long as it has a surface that faces downward and is located above the lower part 6 (corresponding to the lower surface of the second part in this embodiment). Fig. 6 is a cross-sectional view taken along line VI-VI in Fig. 5 when the upper part 5 and the lower part 6 are fixed.
図6に示すように、上方パーツ5の前部5aは、下方パーツ6の上方に位置すると共に下方に向けられた壁面5a1を有する。すなわち、壁面5a1は、前記第2部分の下面に相当する。壁面5a1には、下方に向けて突出した高さ規定突部5cが設けられている。つまり、本実施形態においては、上方パーツ5は、下方に向けて突出した高さ規定突部5cを有している。高さ規定突部5cは、下方パーツ6に対する上方パーツ5の上下方向の位置を規定する高さ規定部10に相当する。言い換えれば、本実施形態の高さ規定部10は、高さ規定突部5cを備える。
As shown in FIG. 6, the front portion 5a of the upper part 5 is located above the lower part 6 and has a wall surface 5a1 facing downward. In other words, the wall surface 5a1 corresponds to the lower surface of the second part. The wall surface 5a1 is provided with a height regulating protrusion 5c that protrudes downward. In other words, in this embodiment, the upper part 5 has a height regulating protrusion 5c that protrudes downward. The height regulating protrusion 5c corresponds to a height regulating portion 10 that regulates the vertical position of the upper part 5 relative to the lower part 6. In other words, the height regulating portion 10 in this embodiment is provided with a height regulating protrusion 5c.
高さ規定突部5cは、下方パーツ6に対して上方から当接する突起である。つまり、高さ規定突部5cの下端が下方パーツ6に上方から当接している。この高さ規定突部5cは、上方パーツ5と下方パーツ6との上下方向における位置関係を規定する。例えば、高さ規定突部5cの壁面5a1からの突出量が大きい場合には、突出量が小さい場合よりも上方パーツ5と下方パーツ6とが上下方向にて遠くなるように位置する。
The height-regulating protrusion 5c is a protrusion that abuts against the lower part 6 from above. In other words, the lower end of the height-regulating protrusion 5c abuts against the lower part 6 from above. This height-regulating protrusion 5c regulates the positional relationship between the upper part 5 and the lower part 6 in the vertical direction. For example, when the height-regulating protrusion 5c protrudes a large amount from the wall surface 5a1, the upper part 5 and the lower part 6 are positioned farther apart in the vertical direction than when the protrusion amount is small.
つまり、下方パーツ6の位置が固定されているとすると、高さ規定突部5cの突出量が大きいほど上方パーツ5が上方に位置することになる。また、下方パーツ6の位置が固定されているとすると、高さ規定突部5cの突出量が小さいほど、上方パーツ5が下方に位置することになる。
In other words, if the position of the lower part 6 is fixed, the greater the amount of protrusion of the height-regulating protrusion 5c, the higher the upper part 5 will be positioned. Also, if the position of the lower part 6 is fixed, the smaller the amount of protrusion of the height-regulating protrusion 5c, the lower the upper part 5 will be positioned.
また、本実施形態においては、図5に示すように、高さ規定突部5c(すなわち高さ規定部10)は、車両100の幅方向(ラジエータグリル1が車両100に取り付けられた状態での車幅方向)に配列されて複数設けられている。高さ規定突部5cは、互いに近接して配置される2つをペアとし、複数のペアが車幅方向に沿って設けられているようにしてもよい。このように高さ規定突部5cが複数設けられていることで、上方パーツ5と下方パーツ6とが複数箇所で高さ規定突部5cを介して当接することになり、下方パーツ6に対して上方パーツ5が車両前方から見て傾くことを抑止することができる。
In addition, in this embodiment, as shown in FIG. 5, multiple height regulating protrusions 5c (i.e., height regulating portions 10) are arranged in the width direction of the vehicle 100 (the vehicle width direction when the radiator grille 1 is attached to the vehicle 100). The height regulating protrusions 5c may be paired in pairs of two that are arranged close to each other, with multiple pairs provided along the vehicle width direction. By providing multiple height regulating protrusions 5c in this manner, the upper part 5 and the lower part 6 come into contact with each other at multiple points via the height regulating protrusions 5c, preventing the upper part 5 from tilting relative to the lower part 6 when viewed from the front of the vehicle.
また、図6に示すように、各々の高さ規定突部5cは、車両100の前後方向(ラジエータグリル1が車両100に取り付けられた状態での車両前後方向)に沿って直線状に延伸して設けられている。このため、各々の高さ規定突部5cが車両前後方向の広い範囲で下方パーツ6と接触することができる。したがって、車幅方向に沿った方向から見て、下方パーツ6に対して上方パーツ5が傾くことを抑止することができる。
Also, as shown in FIG. 6, each height-regulating protrusion 5c is provided extending linearly along the fore-and-aft direction of the vehicle 100 (the fore-and-aft direction of the vehicle when the radiator grille 1 is attached to the vehicle 100). This allows each height-regulating protrusion 5c to come into contact with the lower part 6 over a wide range in the fore-and-aft direction of the vehicle. This makes it possible to prevent the upper part 5 from tilting relative to the lower part 6 when viewed from the direction along the vehicle width direction.
図4に戻り、上壁部5bは、前部5aの上端から後方に突出して形成されており、アッパーガーニッシュ102が固定される板状の部位である。すなわち、上壁部5bは、前部5aの前記第1部分における上端から後方に向けて延びている。上壁部5bは、下方からアッパーガーニッシュ102を支持する。このようにアッパーガーニッシュ102は、上方パーツ5の上壁部5bに固定されているため、上方パーツ5が上方に移動されることで、同様に上方に移動される。つまり、高さ規定突部5cの突出量が大きいほど上方パーツ5が上方に位置するため、アッパーガーニッシュ102も上方に位置することになる。また、高さ規定突部5cの突出量が小さいほど上方パーツ5が下方に位置するため、アッパーガーニッシュ102も下方に位置することになる。
Returning to FIG. 4, the upper wall portion 5b is formed to protrude rearward from the upper end of the front portion 5a, and is a plate-shaped portion to which the upper garnish 102 is fixed. That is, the upper wall portion 5b extends rearward from the upper end of the first portion of the front portion 5a. The upper wall portion 5b supports the upper garnish 102 from below. Since the upper garnish 102 is fixed to the upper wall portion 5b of the upper part 5 in this manner, it is also moved upward when the upper part 5 is moved upward. In other words, the greater the protrusion amount of the height-regulating protrusion 5c, the higher the position of the upper part 5, and therefore the upper garnish 102 is also positioned upward. Also, the smaller the protrusion amount of the height-regulating protrusion 5c, the lower the position of the upper part 5, and therefore the upper garnish 102 is also positioned downward.
上述のようにヘッドライト101は、ラジエータグリル1と直接的に接続されていない。このため、高さ規定突部5cの突出量が大きいほど、ラジエータグリル1に支持されたアッパーガーニッシュ102は、ヘッドライト101から離れるように上方に移動される。また、高さ規定突部5cの突出量が小さいほど、ラジエータグリル1に支持されたアッパーガーニッシュ102は、ヘッドライト101に近づくように下方に移動される。
As mentioned above, the headlights 101 are not directly connected to the radiator grille 1. Therefore, the greater the amount of protrusion of the height-regulating protrusion 5c, the more the upper garnish 102 supported by the radiator grille 1 is moved upward and away from the headlights 101. Also, the smaller the amount of protrusion of the height-regulating protrusion 5c, the more the upper garnish 102 supported by the radiator grille 1 is moved downward and closer to the headlights 101.
図5に示すように、上方パーツ5の前部5aには、仮保持用開口部5a2(被係止部)が設けられている。本実施形態においては、2つの仮保持用開口部5a2が上方パーツ5に設けられている。各々の仮保持用開口部5a2は、車両100の前後方向に貫通して形成されており、下方パーツ6の後述する仮保持爪部6bの突出部6b1が挿入される。なお、仮保持用開口部5a2及び仮保持爪部6bの数は、2つに限定されず、3つ以上設けてもよい。
As shown in FIG. 5, a temporary holding opening 5a2 (retained portion) is provided in the front portion 5a of the upper part 5. In this embodiment, two temporary holding openings 5a2 are provided in the upper part 5. Each temporary holding opening 5a2 is formed penetrating in the fore-and-aft direction of the vehicle 100, and a protrusion 6b1 of a temporary holding claw portion 6b (described later) of the lower part 6 is inserted into it. Note that the number of temporary holding openings 5a2 and temporary holding claw portions 6b is not limited to two, and three or more may be provided.
また、上方パーツ5の前部5aには、複数のネジ挿通孔5dが設けられている。これらのネジ挿通孔5dは、上方パーツ5と下方パーツ6とを締結するためのネジ7が挿通される孔である。
The front portion 5a of the upper part 5 is provided with a number of screw insertion holes 5d. These screw insertion holes 5d are holes through which screws 7 are inserted to fasten the upper part 5 and the lower part 6 together.
図4に示すように、下方パーツ6は、グリル本体部2の下部を形成する樹脂パーツである。下方パーツ6は、バンパや車体フレーム等の外部部品103(車両100が備える部品であってラジエータグリル1と異なる部品)に対して固定される。下方パーツ6は、例えば図5に示すように、基部6aと、仮保持爪部6bと、支持壁6cと、突出壁6dとを有している。
As shown in FIG. 4, the lower part 6 is a resin part that forms the lower part of the grill body 2. The lower part 6 is fixed to an external part 103 (a part that is provided on the vehicle 100 and is different from the radiator grill 1) such as a bumper or a body frame. As shown in FIG. 5, for example, the lower part 6 has a base 6a, a temporary holding claw part 6b, a support wall 6c, and a protruding wall 6d.
基部6aは、ラジエータグリル1の主構造部であり、前後方向に貫通する開口部6a1を複数有している。本実施形態においては、各々の開口部6a1は、車幅方向を長手方向とする長方形状に形成されている。複数の開口部6a1は、上下方向に配列されている。このような基部6aは、開口部6a1同士の間に設けられた横桟部6a2を複数備えている。なお、各々の開口部6a1の形状は、特に限定されるものではない。また、例えば、内燃機関を備えない電気自動車等では、開口部6a1を設けない構成を採用することも可能である。
The base 6a is the main structural part of the radiator grille 1 and has multiple openings 6a1 that penetrate in the front-rear direction. In this embodiment, each opening 6a1 is formed in a rectangular shape with the vehicle width direction as the longitudinal direction. The multiple openings 6a1 are arranged in the vertical direction. Such a base 6a has multiple horizontal bar portions 6a2 provided between the openings 6a1. The shape of each opening 6a1 is not particularly limited. Also, for example, in an electric vehicle or the like that does not have an internal combustion engine, it is possible to adopt a configuration that does not have openings 6a1.
各々の横桟部6a2には、第2加飾用パーツ4を取り付けるための取付部6a3が複数設けられている。基部6aの上縁部6a4は、上方パーツ5が取り付けられる部位である。この上縁部6a4には、各々の仮保持爪部6bの設置位置に合わせて爪用開口部6a5が設けられている。これらの爪用開口部6a5は、基部6aを車両100の前後方向に貫通して設けられている。このような爪用開口部6a5が設けられることで、仮保持爪部6bは、車両100の前後方向に弾性変形可能である。
Each horizontal bar portion 6a2 is provided with a plurality of mounting portions 6a3 for mounting the second decorative part 4. The upper edge portion 6a4 of the base portion 6a is the portion where the upper part 5 is mounted. This upper edge portion 6a4 is provided with claw openings 6a5 in accordance with the installation positions of each temporary holding claw portion 6b. These claw openings 6a5 are provided penetrating the base portion 6a in the fore-and-aft direction of the vehicle 100. By providing such claw openings 6a5, the temporary holding claw portions 6b can elastically deform in the fore-and-aft direction of the vehicle 100.
なお、基部6aの上縁部6a4には、ネジ7が螺合される雌ネジ部6a6が複数設けられている。各々の雌ネジ部6a6は、下方パーツ6に上方パーツ5が取り付けられた状態で、上方パーツ5のネジ挿通孔5dと重なる位置に配置されている。各々の雌ネジ部6a6に、ネジ挿通孔5dに挿通されたネジ7が螺合されることで、下方パーツ6と上方パーツ5とが締結される。また、基部6aの上縁部6a4には、第1加飾用パーツ3を取り付けるための取付部6a7が複数設けられている。
The upper edge 6a4 of the base 6a is provided with a plurality of female threaded portions 6a6 into which the screws 7 are screwed. Each female threaded portion 6a6 is positioned so as to overlap with a screw insertion hole 5d of the upper part 5 when the upper part 5 is attached to the lower part 6. The lower part 6 and the upper part 5 are fastened together by screwing the screw 7 inserted into the screw insertion hole 5d into each female threaded portion 6a6. The upper edge 6a4 of the base 6a is also provided with a plurality of mounting portions 6a7 for mounting the first decorative part 3.
このような基部6aは、不図示の取付部を介して、バンパや車体フレーム等の外部部品103に対して固定されている。つまり、本実施形態においては、下方パーツ6がバンパや車体フレーム等の外部部品103に対して固定されている。
Such a base 6a is fixed to an external part 103 such as a bumper or a vehicle frame via an attachment part (not shown). In other words, in this embodiment, the lower part 6 is fixed to an external part 103 such as a bumper or a vehicle frame.
仮保持爪部6bは、基部6aの各々の爪用開口部6a5の上縁(すなわち、下方を向く内面)から垂下するように設けられている。本実施形態においては、爪用開口部6a5が2つ設けられているため、仮保持爪部6bも2つ設けられている。図7は、上方パーツ5と下方パーツ6が固定された状態における図5のVII-VII線視断面図である。図7に示すように、各々の仮保持爪部6bは、車両100の前後方向に撓み変形が可能な厚さ寸法に形成されている。また、各々の仮保持爪部6bは、車両100の後方に向けて突出した突出部6b1を有している。
The temporary retaining claw portions 6b are arranged to hang down from the upper edge (i.e., the inner surface facing downward) of each claw opening 6a5 of the base 6a. In this embodiment, since two claw openings 6a5 are provided, two temporary retaining claw portions 6b are also provided. Figure 7 is a cross-sectional view taken along line VII-VII in Figure 5 when the upper part 5 and the lower part 6 are fixed. As shown in Figure 7, each temporary retaining claw portion 6b is formed with a thickness dimension that allows it to bend and deform in the fore-and-aft direction of the vehicle 100. In addition, each temporary retaining claw portion 6b has a protrusion 6b1 that protrudes toward the rear of the vehicle 100.
各々の仮保持爪部6bは、下方パーツ6に対して上方パーツ5を取り付ける場合に、上方から下方に移動する上方パーツ5に突出部6b1が接触することで、車両100の前方側に向けて弾性変形する。その後、各々の仮保持爪部6bは、上方パーツ5に設けられた仮保持用開口部5a2が突出部6b1に到達すると、元の形状に復元する。この結果、仮保持爪部6bの突出部6b1が仮保持用開口部5a2に入り込む。このような仮保持爪部6bの突出部6b1が仮保持用開口部5a2に入り込むことで、上方パーツ5を下方パーツ6から上方に抜き出すことが防止される。なお、仮保持用開口部5a2の上下方向の大きさは、突出部6b1の上下方向の幅よりも大きい。このため、突出部6b1が仮保持用開口部5a2に挿入されている状態でも、上方パーツ5は下方パーツ6に対して僅かに上下移動可能となっている。このため、高さ規定突部5cを用いた上方パーツ5の上下方向の位置の調整が、突出部6b1によって妨げられることがない。
When the upper part 5 is attached to the lower part 6, the protrusion 6b1 of each temporary holding claw portion 6b comes into contact with the upper part 5 moving downward, and the temporary holding claw portion 6b is elastically deformed toward the front side of the vehicle 100. Thereafter, when the temporary holding opening 5a2 provided in the upper part 5 reaches the protrusion 6b1, each temporary holding claw portion 6b restores its original shape. As a result, the protrusion 6b1 of the temporary holding claw portion 6b enters the temporary holding opening 5a2. The protrusion 6b1 of the temporary holding claw portion 6b enters the temporary holding opening 5a2, preventing the upper part 5 from being pulled out upward from the lower part 6. The vertical size of the temporary holding opening 5a2 is greater than the vertical width of the protrusion 6b1. Therefore, even when the protrusion 6b1 is inserted into the temporary holding opening 5a2, the upper part 5 can move slightly vertically relative to the lower part 6. Therefore, the protrusion 6b1 does not prevent the adjustment of the vertical position of the upper part 5 using the height-regulating protrusion 5c.
図8は、上方パーツ5と下方パーツ6が固定された状態における図5のVIII-VIII線視断面図である。図7及び図8に示すように、支持壁6cは、爪用開口部6a5の下方に位置する基部6aの部位に接続されている。支持壁6cは、基部6aから車両100の後方に向けて突出した後、上方に向けて屈曲されている。このような支持壁6cは、基部6aの後面と平行な立壁部6c1を有している。すなわち、支持壁6cは、基部6aから後方に延びる前後延在部6c2と、前後延在部6c2の後端から上方に延びる立壁部6c1とを有している。立壁部6c1は、車幅方向から見て基部6aから後方に離間して配置されている。基部6aの後面と立壁部6c1の前面との離間寸法は、上方パーツ5の前部5aの下縁部(すなわち前記第3部分)が挿入可能な寸法とされている。このため、上方パーツ5の下縁部を基部6aと立壁部6c1との間に差し込むことができる。基部6aと立壁部6c1との間に差し込まれた上方パーツ5は、基部6aが上方パーツ5の下縁部の前側に位置し、立壁部6c1が当該下縁部の後側に位置することになる。この結果、上方パーツ5は、車両100の前後方向への移動が規制される。つまり、本実施形態においては、下方パーツ6に取り付けられた上方パーツ5が、基部6aと立壁部6c1との間に挟まれることで、車両100の前後方向への移動が規制される。
8 is a cross-sectional view taken along line VIII-VIII in FIG. 5 when the upper part 5 and the lower part 6 are fixed. As shown in FIGS. 7 and 8, the support wall 6c is connected to a portion of the base 6a located below the claw opening 6a5. The support wall 6c protrudes from the base 6a toward the rear of the vehicle 100, and is then bent upward. Such a support wall 6c has a vertical wall portion 6c1 parallel to the rear surface of the base 6a. That is, the support wall 6c has a front-rear extending portion 6c2 extending rearward from the base 6a, and a vertical wall portion 6c1 extending upward from the rear end of the front-rear extending portion 6c2. The vertical wall portion 6c1 is disposed rearward and spaced apart from the base 6a when viewed in the vehicle width direction. The distance between the rear surface of the base 6a and the front surface of the vertical wall portion 6c1 is set to a dimension that allows the lower edge portion of the front portion 5a of the upper part 5 (i.e., the third portion) to be inserted. Therefore, the lower edge of the upper part 5 can be inserted between the base 6a and the standing wall 6c1. When the upper part 5 is inserted between the base 6a and the standing wall 6c1, the base 6a is located in front of the lower edge of the upper part 5, and the standing wall 6c1 is located behind the lower edge. As a result, the movement of the upper part 5 in the fore-and-aft direction of the vehicle 100 is restricted. In other words, in this embodiment, the upper part 5 attached to the lower part 6 is sandwiched between the base 6a and the standing wall 6c1, thereby restricting the movement of the vehicle 100 in the fore-and-aft direction.
突出壁6dは、爪用開口部6a5の下縁(すなわち、上方を向く内面)から上方に向けて突出した壁部である。この突出壁6dは、基部6aと立壁部6c1との間に位置する上方パーツ5の下縁部の前方に位置する。このような突出壁6dが設けられることで、下方パーツ6に取り付けられた上方パーツ5は、基部6aに加えて突出壁6dによっても、前方への移動を規制される。このため、下方パーツ6に取り付けられた上方パーツ5の車両100の前後方向への移動をより確実に規制することができる。
The protruding wall 6d is a wall that protrudes upward from the lower edge of the claw opening 6a5 (i.e., the inner surface facing upward). This protruding wall 6d is located in front of the lower edge of the upper part 5, which is located between the base 6a and the standing wall 6c1. By providing such a protruding wall 6d, the forward movement of the upper part 5 attached to the lower part 6 is restricted not only by the base 6a but also by the protruding wall 6d. Therefore, the movement of the upper part 5 attached to the lower part 6 in the fore-and-aft direction of the vehicle 100 can be more reliably restricted.
各々のネジ7は、上方パーツ5に設けられたネジ挿通孔5dに挿通された状態で、下方パーツ6の雌ネジ部6a6に螺合される。これらのネジ7によって、上述のように上方パーツ5と下方パーツ6とが締結される。上方パーツ5と下方パーツ6の締結構造としては、雌ネジ部6a6に螺合されるネジ7に限定されず、ボルトとナットを用いた締結構造や、弾性変形可能な係止爪を有するピン部材等を用いてもよい。なお、本実施形態のネジ挿通孔5dの上下方向の大きさは、ネジ7の外径よりも大きいため、ネジ7がネジ挿通孔5dに挿通されていても、上方パーツ5は下方パーツ6に対する上下方向の移動代を有している。このため、高さ規定突部5cを用いた上方パーツ5の上下方向の位置の調整を行った後であっても、ネジ7を雌ネジ部6a6に適切に螺合できる。
Each screw 7 is inserted into a screw insertion hole 5d provided in the upper part 5 and is screwed into the female threaded portion 6a6 of the lower part 6. The upper part 5 and the lower part 6 are fastened together by these screws 7 as described above. The fastening structure of the upper part 5 and the lower part 6 is not limited to the screw 7 screwed into the female threaded portion 6a6, but may be a fastening structure using a bolt and a nut, or a pin member having an elastically deformable locking claw. In addition, since the vertical size of the screw insertion hole 5d in this embodiment is larger than the outer diameter of the screw 7, even if the screw 7 is inserted into the screw insertion hole 5d, the upper part 5 has a vertical movement margin relative to the lower part 6. Therefore, even after the vertical position of the upper part 5 is adjusted using the height regulation protrusion 5c, the screw 7 can be properly screwed into the female threaded portion 6a6.
第1加飾用パーツ3は、上方パーツ5と下方パーツ6との接続部分を車両の前方から覆う樹脂パーツである。図4に示すように、第1加飾用パーツ3は、後方に向けて突出した係止爪3aを有している。この係止爪3aは複数設けられている。各々の係止爪3aは、下方パーツ6に設けられた取付部6a7に挿入されることで、下方パーツ6に係止されている。これらの係止爪3aが下方パーツ6に係止されることで、第1加飾用パーツ3は、下方パーツ6に固定されている。
The first decorative part 3 is a resin part that covers the connection between the upper part 5 and the lower part 6 from the front of the vehicle. As shown in FIG. 4, the first decorative part 3 has a locking claw 3a that protrudes toward the rear. There are multiple locking claws 3a. Each locking claw 3a is inserted into an attachment portion 6a7 provided on the lower part 6, and thereby locked to the lower part 6. The first decorative part 3 is fixed to the lower part 6 by locking these locking claws 3a to the lower part 6.
第2加飾用パーツ4は、下方パーツ6の横桟部6a2の前方に配置される樹脂パーツである。図4に示すように、第2加飾用パーツ4は、横桟部6a2ごとに複数設けられている。各々の第2加飾用パーツ4は、後方に向けて突出した係止爪4aを有している。係止爪4aは、第2加飾用パーツ4ごとに複数設けられている。各々の係止爪4aは、下方パーツ6に設けられた取付部6a3に挿入されることで、下方パーツ6に係止されている。これらの係止爪4aが下方パーツ6に係止されることで、第2加飾用パーツ4は、下方パーツ6に固定されている。
The second decorative part 4 is a resin part that is placed in front of the horizontal bar portion 6a2 of the lower part 6. As shown in FIG. 4, multiple second decorative parts 4 are provided for each horizontal bar portion 6a2. Each second decorative part 4 has a locking claw 4a that protrudes rearward. Multiple locking claws 4a are provided for each second decorative part 4. Each locking claw 4a is inserted into an attachment portion 6a3 provided on the lower part 6, and thereby locked to the lower part 6. The second decorative part 4 is fixed to the lower part 6 by locking these locking claws 4a to the lower part 6.
このような構成の本実施形態のラジエータグリル1を組み立てる場合には、まず下方パーツ6に対して、上方パーツ5を取り付ける。このとき、上方パーツ5の前部5aの下縁部が、下方パーツ6の基部6aと支持壁6cの立壁部6c1との間に挿入される。この状態で、上方パーツ5を下方パーツ6に対して下方に相対移動させる。
When assembling the radiator grille 1 of this embodiment with such a configuration, first the upper part 5 is attached to the lower part 6. At this time, the lower edge of the front part 5a of the upper part 5 is inserted between the base part 6a of the lower part 6 and the vertical wall part 6c1 of the support wall 6c. In this state, the upper part 5 is moved downward relative to the lower part 6.
これによって、上方パーツ5の前部5aに設けられた仮保持用開口部5a2に、下方パーツ6の仮保持爪部6bの突出部6b1が入り込む。このため、上方パーツ5が下方パーツ6から上下方向及び幅方向に抜けることが防止される。また、上方パーツ5の前部5aが下方パーツ6の基部6aと支持壁6cの立壁部6c1とで挟み込まれるため、上方パーツ5が下方パーツ6に対して前後方向に移動することが規制される。したがって、ネジ7による締結前であっても、上方パーツ5が下方パーツ6に仮保持された状態となる。
As a result, the protrusion 6b1 of the temporary holding claw portion 6b of the lower part 6 fits into the temporary holding opening 5a2 provided in the front portion 5a of the upper part 5. This prevents the upper part 5 from slipping out of the lower part 6 in the vertical and width directions. In addition, because the front portion 5a of the upper part 5 is sandwiched between the base portion 6a of the lower part 6 and the vertical wall portion 6c1 of the support wall 6c, movement of the upper part 5 in the front-to-rear direction relative to the lower part 6 is restricted. Therefore, even before fastening with the screws 7, the upper part 5 is temporarily held by the lower part 6.
さらに、上方パーツ5に設けられた高さ規定突部5cが下方パーツ6の基部6aの上端に当接することで、下方パーツ6に対する上方パーツ5の高さ方向の位置が定まる。高さ規定突部5cの突出量は、予めアッパーガーニッシュ102がヘッドライト101と干渉しないように設定されている。このため、高さ規定突部5cに下方パーツ6の基部6aの上端に当接することで、上方パーツ5の高さ方向の位置は、アッパーガーニッシュ102がヘッドライト101と干渉しない位置に定まる。
Furthermore, the height-direction position of the upper part 5 relative to the lower part 6 is determined by the height-regulating protrusion 5c provided on the upper part 5 abutting against the upper end of the base 6a of the lower part 6. The amount of protrusion of the height-regulating protrusion 5c is set in advance so that the upper garnish 102 does not interfere with the headlight 101. Therefore, by the height-regulating protrusion 5c abutting against the upper end of the base 6a of the lower part 6, the height-direction position of the upper part 5 is determined at a position where the upper garnish 102 does not interfere with the headlight 101.
その後、ネジ7によって上方パーツ5と下方パーツ6とを締結する。さらに、第1加飾用パーツ3を下方パーツ6に取り付ける。また、第2加飾用パーツ4を下方パーツ6に取り付ける。なお、第1加飾用パーツ3と第2加飾用パーツ4の取り付けタイミングは変更可能である。
Then, the upper part 5 and the lower part 6 are fastened together with the screws 7. Furthermore, the first decorative part 3 is attached to the lower part 6. Furthermore, the second decorative part 4 is attached to the lower part 6. Note that the timing of attaching the first decorative part 3 and the second decorative part 4 can be changed.
続いて、図9を参照して、本実施形態のラジエータグリル1の設計方法について説明する。つまり、以下に説明するラジエータグリル1の設計方法は、第1外装部品(ヘッドライト101)の上方に位置する第2外装部品(アッパーガーニッシュ102)を支持するラジエータグリル1の設計方法である。
Next, a method for designing the radiator grille 1 of this embodiment will be described with reference to FIG. 9. In other words, the method for designing the radiator grille 1 described below is a method for designing a radiator grille 1 that supports a second exterior part (upper garnish 102) that is located above a first exterior part (headlight 101).
本実施形態のラジエータグリル1の設計方法では、まず、上方パーツ5と下方パーツ6との形状を仮決定する(形状仮決定工程S1)。ここでは、上方パーツ5に設けられた高さ規定突部5cの突出量を仮決定する。例えば、ここでの高さ規定突部5cの突出量は、高さ規定突部5cの突出量を後に増加可能な量に設定しておくことが好ましい。つまり、上方パーツ5の形状は、後に下方パーツ6に対して上方に移動できる余地を残した形状とすることが好ましい。さらに、ここでの高さ規定突部5cの突出量は、高さ規定突部5cの突出量を後に減少可能な量に設定しておくことが好ましい。つまり、上方パーツ5の形状は、後に下方パーツ6に対して下方に移動できる余地を残した形状とすることが好ましい。
In the design method of the radiator grille 1 of this embodiment, first, the shapes of the upper part 5 and the lower part 6 are provisionally determined (provisional shape determination step S1). Here, the amount of protrusion of the height regulating protrusion 5c provided on the upper part 5 is provisionally determined. For example, it is preferable to set the amount of protrusion of the height regulating protrusion 5c here to an amount that can be increased later. In other words, it is preferable to set the shape of the upper part 5 to a shape that leaves room for it to move upward relative to the lower part 6 later. Furthermore, it is preferable to set the amount of protrusion of the height regulating protrusion 5c here to an amount that can be decreased later. In other words, it is preferable to set the shape of the upper part 5 to a shape that leaves room for it to move downward relative to the lower part 6 later.
続いて、ヘッドライト101とアッパーガーニッシュ102との位置関係を確認する(位置関係確認工程S2)。ここでは、形状仮決定工程S1で形状が仮決定された上方パーツ5と下方パーツ6を用いて、ヘッドライト101とアッパーガーニッシュ102との位置関係を確認する。位置関係確認工程S2は、シミュレーションによって、ヘッドライト101とアッパーガーニッシュ102との位置関係を確認してもよい。ただし、実際に実物を作成すると共に組み立てることで、ヘッドライト101とアッパーガーニッシュ102との位置関係を確認するとよりよい。
Next, the positional relationship between the headlight 101 and the upper garnish 102 is confirmed (positional relationship confirmation process S2). Here, the positional relationship between the headlight 101 and the upper garnish 102 is confirmed using the upper part 5 and lower part 6 whose shapes have been provisionally determined in the shape provisional determination process S1. In the positional relationship confirmation process S2, the positional relationship between the headlight 101 and the upper garnish 102 may be confirmed by simulation. However, it is better to confirm the positional relationship between the headlight 101 and the upper garnish 102 by actually creating and assembling the actual parts.
続いて、高さ規定突部5cの突出量を調整する(高さ調整工程S3)。ここでは、位置関係確認工程S2の確認結果に基づいて、高さ規定突部5cの突出量を調整する。例えば、位置関係確認工程S2にて、アッパーガーニッシュ102がヘッドライト101と干渉するとの確認結果が得られた場合には、高さ規定突部5cの突出量を増加させる。高さ規定突部5cの突出量を増加させることで、上方パーツ5の位置が上昇し、同時にアッパーガーニッシュ102の位置を上昇させることができる。したがって、アッパーガーニッシュ102とヘッドライト101との干渉を回避できる。
Next, the amount of protrusion of the height-regulating protrusion 5c is adjusted (height adjustment process S3). Here, the amount of protrusion of the height-regulating protrusion 5c is adjusted based on the confirmation result of the positional relationship confirmation process S2. For example, if the confirmation result obtained in the positional relationship confirmation process S2 is that the upper garnish 102 will interfere with the headlight 101, the amount of protrusion of the height-regulating protrusion 5c is increased. By increasing the amount of protrusion of the height-regulating protrusion 5c, the position of the upper part 5 is raised, and at the same time, the position of the upper garnish 102 can be raised. Therefore, interference between the upper garnish 102 and the headlight 101 can be avoided.
なお、上方パーツ5は、樹脂の射出成形によって形成される。したがって、射出成形時に用いる金型の形状を調整することで、高さ規定突部5cの突出量を調整することができる。例えば、高さ規定突部5cの突出量を増加させる場合には、金型の一部を削ることで、容易に高さ規定突部5cの突出量を増加させることができる。
The upper part 5 is formed by injection molding of resin. Therefore, the amount of protrusion of the height-regulating protrusion 5c can be adjusted by adjusting the shape of the mold used during injection molding. For example, if the amount of protrusion of the height-regulating protrusion 5c needs to be increased, the amount of protrusion of the height-regulating protrusion 5c can be easily increased by removing part of the mold.
また、アッパーガーニッシュ102がヘッドライト101に対して上方に離れすぎているとの確認結果が得られた場合には、高さ規定突部5cの突出量を減少させる。高さ規定突部5cの突出量を減少させることで、上方パーツ5の位置が下降し、同時にアッパーガーニッシュ102の位置を下降させることができる。したがって、アッパーガーニッシュ102とヘッドライト101との隙間を減少させることができる。
In addition, if it is determined that the upper garnish 102 is too far above the headlight 101, the amount of protrusion of the height-regulating protrusion 5c is reduced. By reducing the amount of protrusion of the height-regulating protrusion 5c, the position of the upper part 5 is lowered, and at the same time, the position of the upper garnish 102 can be lowered. Therefore, the gap between the upper garnish 102 and the headlight 101 can be reduced.
続いて、下方パーツ6と上方パーツ5との形状を決定する(決定工程S4)。ここでは、高さ調整工程S3で突出量が調整された高さ規定突部5cを含むようにして、下方パーツ6と上方パーツ5との形状を決定する。つまり、高さ調整工程S3で調整された高さ規定突部5cの突出量に基づいて、上方パーツ5の形状が決定される。なお、高さ規定突部5cの突出量が増加余地あるいは減少余地がない場合には、下方パーツ6の形状を変更して、上方パーツ5の高さ位置を決定してもよい。
Next, the shapes of the lower part 6 and the upper part 5 are determined (determination step S4). Here, the shapes of the lower part 6 and the upper part 5 are determined so as to include the height-regulating protrusion 5c whose protrusion amount has been adjusted in the height adjustment step S3. In other words, the shape of the upper part 5 is determined based on the protrusion amount of the height-regulating protrusion 5c adjusted in the height adjustment step S3. Note that if there is no room to increase or decrease the protrusion amount of the height-regulating protrusion 5c, the shape of the lower part 6 may be changed to determine the height position of the upper part 5.
なお、第1加飾用パーツ3及び第2加飾用パーツ4の形状は、例えば、図9に示す工程と別に決定することができる。したがって、第1加飾用パーツ3及び第2加飾用パーツ4の形状は、下方パーツ6及び上方パーツ5の形状が決定した後に決定することができる。また、第1加飾用パーツ3及び第2加飾用パーツ4の形状は、下方パーツ6及び上方パーツ5の形状が決定する前に決定してもよい。さらに、第1加飾用パーツ3及び第2加飾用パーツ4の形状は、下方パーツ6及び上方パーツ5の形状と並行して決定してもよい。
The shapes of the first decorative part 3 and the second decorative part 4 can be determined, for example, separately from the process shown in FIG. 9. Therefore, the shapes of the first decorative part 3 and the second decorative part 4 can be determined after the shapes of the lower part 6 and the upper part 5 are determined. Also, the shapes of the first decorative part 3 and the second decorative part 4 may be determined before the shapes of the lower part 6 and the upper part 5 are determined. Furthermore, the shapes of the first decorative part 3 and the second decorative part 4 may be determined in parallel with the shapes of the lower part 6 and the upper part 5.
このような本実施形態のラジエータグリル1の設計方法に設計されたラジエータグリル1を製造することで、アッパーガーニッシュ102とヘッドライト101との位置関係を適切にすることが可能なラジエータグリル1を量産することができる。
By manufacturing a radiator grill 1 designed using the design method of the radiator grill 1 of this embodiment, it is possible to mass-produce radiator grills 1 that can appropriately adjust the positional relationship between the upper garnish 102 and the headlights 101.
以上のような本実施形態のラジエータグリル1は、ヘッドライト101の上方に位置するアッパーガーニッシュ102を支持する。また、本実施形態のラジエータグリル1は、下方パーツ6と、上方パーツ5とを備える。下方パーツ6は、外部部品103に対して固定される。上方パーツ5は、アッパーガーニッシュ102が固定されると共に、下方パーツ6の上方に位置して下方パーツ6に締結されている。また、本実施形態のラジエータグリル1は、下方パーツ6と上方パーツ5との一方である上方パーツ5に設けられると共に他方である下方パーツ6に上方向から当接する高さ規定突部5cを有する。
The radiator grill 1 of this embodiment as described above supports the upper garnish 102 located above the headlight 101. The radiator grill 1 of this embodiment also includes a lower part 6 and an upper part 5. The lower part 6 is fixed to an external part 103. The upper part 5 has the upper garnish 102 fixed thereto, and is located above the lower part 6 and fastened to the lower part 6. The radiator grill 1 of this embodiment also has a height-regulating protrusion 5c that is provided on the upper part 5, which is one of the lower part 6 and upper part 5, and abuts the lower part 6, which is the other, from above.
本実施形態のラジエータグリル1によれば、ラジエータグリル1が上方パーツ5と下方パーツ6とに分割形成されている。さらに高さ規定突部5cの高さ寸法を調整することで、下方パーツ6に対する上方パーツ5の高さ方向の位置を変更することができる。したがって、例えば、アッパーガーニッシュ102のヘッドライト101に対する位置関係を修正する必要が生じた場合には、高さ規定突部5cの高さ寸法(すなわち突出量)のみを調整することで、ラジエータグリル1の全体形状を見直すことなく、アッパーガーニッシュ102のヘッドライト101に対する高さ方向の位置調整を行うことができる。よって、本実施形態のラジエータグリル1によれば、アッパーガーニッシュ102の高さ方向の位置を容易に調整することができる。
According to the radiator grille 1 of this embodiment, the radiator grille 1 is divided into an upper part 5 and a lower part 6. Furthermore, by adjusting the height dimension of the height-regulating protrusion 5c, the heightwise position of the upper part 5 relative to the lower part 6 can be changed. Therefore, for example, if it becomes necessary to correct the positional relationship of the upper garnish 102 relative to the headlight 101, the heightwise position of the upper garnish 102 relative to the headlight 101 can be adjusted by adjusting only the height dimension (i.e., the amount of protrusion) of the height-regulating protrusion 5c, without having to reconsider the overall shape of the radiator grille 1. Therefore, according to the radiator grille 1 of this embodiment, the heightwise position of the upper garnish 102 can be easily adjusted.
また、本実施形態のラジエータグリル1において高さ規定突部5cは、車両100の幅方向に配列されて複数設けられている。このため、本実施形態のラジエータグリル1は、上方パーツ5と下方パーツ6とが車幅方向において複数箇所で当接することになり、下方パーツ6に対して上方パーツ5が車両100の前方から見て傾くことを抑止することができる。
Furthermore, in the radiator grille 1 of this embodiment, multiple height-regulating protrusions 5c are provided and arranged in the width direction of the vehicle 100. Therefore, in the radiator grille 1 of this embodiment, the upper part 5 and the lower part 6 abut at multiple points in the vehicle width direction, and it is possible to prevent the upper part 5 from tilting relative to the lower part 6 when viewed from the front of the vehicle 100.
また、本実施形態のラジエータグリル1において高さ規定突部5cは、車両100の前後方向に直線状に延伸して設けられている。このため、高さ規定突部5cが車両前後方向の広い範囲で下方パーツ6と接触することができる。したがって、本実施形態のラジエータグリル1は、車幅方向に沿った方向から見て、下方パーツ6に対して上方パーツ5が傾くことを抑止することができる。
In addition, in the radiator grille 1 of this embodiment, the height-regulating protrusion 5c is provided extending linearly in the fore-and-aft direction of the vehicle 100. This allows the height-regulating protrusion 5c to come into contact with the lower part 6 over a wide range in the fore-and-aft direction of the vehicle. Therefore, the radiator grille 1 of this embodiment can prevent the upper part 5 from tilting relative to the lower part 6 when viewed from the direction along the vehicle width direction.
また、本実施形態のラジエータグリル1は、下方パーツ6と上方パーツ5との一方である下方パーツ6に設けられる仮保持爪部6bを備える。また、本実施形態のラジエータグリル1は、下方パーツ6と上方パーツ5との他方である上方パーツ5に設けられると共に仮保持爪部6bを係止可能な仮保持用開口部5a2を備える。
The radiator grille 1 of this embodiment also includes a temporary retaining claw portion 6b provided on the lower part 6, which is one of the lower part 6 and the upper part 5. The radiator grille 1 of this embodiment also includes a temporary retaining opening 5a2 provided on the upper part 5, which is the other of the lower part 6 and the upper part 5, and capable of engaging the temporary retaining claw portion 6b.
このような本実施形態のラジエータグリル1は、組み立て時において、下方パーツ6と上方パーツ5とを締結する前に、下方パーツ6に対して上方パーツ5を仮保持することができる。このため、下方パーツ6と上方パーツ5との位置関係が安定した状態で、下方パーツ6と上方パーツ5とを締結作業を行うことができる。
In the radiator grille 1 of this embodiment, the upper part 5 can be temporarily held relative to the lower part 6 before the lower part 6 and the upper part 5 are fastened together during assembly. This allows the lower part 6 and the upper part 5 to be fastened together with the positional relationship between them being stable.
また、本実施形態のラジエータグリル1は、外部から視認可能な複数の加飾用パーツ(第1加飾用パーツ3及び第2加飾用パーツ4)を備える。これらの第1加飾用パーツ3及び第2加飾用パーツ4は、下方パーツ6に取り付けられている。つまり、本実施形態のラジエータグリル1は、全ての加飾用パーツが下方パーツ6に取り付けられている。このため、加飾用パーツの重量が上方パーツ5に掛かることを防止でき、加飾用パーツを取り付けることで、アッパーガーニッシュ102の位置が変化することを防止することができる。
The radiator grille 1 of this embodiment also includes multiple decorative parts (first decorative part 3 and second decorative part 4) that are visible from the outside. These first decorative part 3 and second decorative part 4 are attached to the lower part 6. In other words, in the radiator grille 1 of this embodiment, all decorative parts are attached to the lower part 6. This prevents the weight of the decorative parts from being placed on the upper part 5, and by attaching the decorative parts, it is possible to prevent the position of the upper garnish 102 from changing.
また、本実施形態のラジエータグリル1の設計方法は、ヘッドライト101の上方に位置するアッパーガーニッシュ102を支持するラジエータグリル1の設計方法である。本実施形態のラジエータグリル1の設計方法は、形状仮決定工程S1と、位置関係確認工程S2と、高さ調整工程S3と、決定工程S4とを有する。
The design method for the radiator grille 1 of this embodiment is a design method for the radiator grille 1 that supports the upper garnish 102 located above the headlight 101. The design method for the radiator grille 1 of this embodiment includes a shape tentative determination process S1, a positional relationship confirmation process S2, a height adjustment process S3, and a determination process S4.
形状仮決定工程S1は、下方パーツ6と上方パーツ5との形状を仮決定する工程である。位置関係確認工程S2は、形状仮決定工程S1で仮決定された形状にて、ヘッドライト101とアッパーガーニッシュ102との位置関係を確認する工程である。高さ調整工程S3は、位置関係確認工程S2の確認結果に基づいて、高さ規定突部5cの突出量を調整する工程である。決定工程S4は、高さ調整工程S3で突出量が調整された高さ規定突部5cを含んで下方パーツ6と上方パーツ5との形状を決定する工程である。
The provisional shape determination process S1 is a process for provisionally determining the shape of the lower part 6 and the upper part 5. The positional relationship confirmation process S2 is a process for confirming the positional relationship between the headlight 101 and the upper garnish 102 in the shape provisionally determined in the provisional shape determination process S1. The height adjustment process S3 is a process for adjusting the protrusion amount of the height-regulating protrusion 5c based on the confirmation result of the positional relationship confirmation process S2. The determination process S4 is a process for determining the shape of the lower part 6 and the upper part 5, including the height-regulating protrusion 5c whose protrusion amount has been adjusted in the height adjustment process S3.
このような本実施形態のラジエータグリル1の設計方法によれば、位置関係確認工程S2にて、アッパーガーニッシュ102のヘッドライト101に対する位置関係を修正する必要が生じた場合には、高さ規定突部5cの高さ寸法(すなわち突出量)のみを調整することで、ラジエータグリル1の全体形状を見直すことなく、アッパーガーニッシュ102のヘッドライト101に対する高さ方向の位置調整を行うことができる。よって、本実施形態のラジエータグリル1の設計方法によれば、アッパーガーニッシュ102とヘッドライト101との位置関係を適切に設定できる。
According to the design method of the radiator grille 1 of this embodiment, if it becomes necessary to modify the positional relationship of the upper garnish 102 relative to the headlight 101 in the positional relationship confirmation step S2, the height dimension (i.e., the amount of protrusion) of the height-regulating protrusion 5c alone can be adjusted to adjust the height direction position of the upper garnish 102 relative to the headlight 101 without reconsidering the overall shape of the radiator grille 1. Therefore, according to the design method of the radiator grille 1 of this embodiment, the positional relationship between the upper garnish 102 and the headlight 101 can be appropriately set.
続いて、本発明の第2実施形態について以下に説明する。
本実施形態において、前記第1実施形態と同等の構成については同一の符号を付し、その説明を省略または簡略化する。 Next, a second embodiment of the present invention will be described below.
In this embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted or simplified.
本実施形態において、前記第1実施形態と同等の構成については同一の符号を付し、その説明を省略または簡略化する。 Next, a second embodiment of the present invention will be described below.
In this embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted or simplified.
図10は、本実施形態におけるラジエータグリル1の上方パーツ5の一部及び下方パーツ6の一部を示す正面図である。図10は、上方パーツ5と下方パーツ6とが、後述するピン部材11によって互いに連結された状態を示している。図11は、図10のXI-XI線視断面図である。図12は、本実施形態における複数の第1貫通孔8及び複数の第2貫通孔9の配置を示す正面図であって、(a)は、上方パーツ5に形成された複数の第1貫通孔8の配置を示し、(b)は、下方パーツ6に形成された複数の第2貫通孔9の配置を示している。本実施形態の上方パーツ5及び下方パーツ6は樹脂によって形成されているが、これに限定されず金属や木材等によって形成されてもよい。
FIG. 10 is a front view showing a part of the upper part 5 and a part of the lower part 6 of the radiator grille 1 in this embodiment. FIG. 10 shows the upper part 5 and the lower part 6 connected to each other by a pin member 11 described later. FIG. 11 is a cross-sectional view taken along line XI-XI in FIG. 10. FIG. 12 is a front view showing the arrangement of the first through holes 8 and the second through holes 9 in this embodiment, where (a) shows the arrangement of the first through holes 8 formed in the upper part 5 and (b) shows the arrangement of the second through holes 9 formed in the lower part 6. The upper part 5 and the lower part 6 in this embodiment are made of resin, but are not limited to this and may be made of metal, wood, etc.
図10、11に示すように、上方パーツ5の前部5aの下端部(すなわち前記第3部分)には、前後方向に貫通する複数の第1貫通孔8が形成されている。下方パーツ6の基部6aの上端部には、前後方向に貫通する複数の第2貫通孔9が形成されている。なお、本実施形態の第1貫通孔8及び第2貫通孔9はいずれも前後方向(すなわち水平方向)に貫通して延びているが、水平方向から僅かに傾斜した方向に延びていてもよく、言い換えれば、鉛直方向以外の方向に延びていればよい。
As shown in Figures 10 and 11, a plurality of first through holes 8 penetrating in the front-rear direction are formed in the lower end of the front portion 5a of the upper part 5 (i.e., the third portion). A plurality of second through holes 9 penetrating in the front-rear direction are formed in the upper end of the base 6a of the lower part 6. Note that although the first through holes 8 and second through holes 9 in this embodiment both extend in the front-rear direction (i.e., the horizontal direction), they may extend in a direction slightly inclined from the horizontal direction, in other words, they may extend in a direction other than the vertical direction.
本実施形態の複数の第1貫通孔8は、4つの第1貫通孔8a、8b、8c及び8dを備え、複数の第2貫通孔9は、4つの第2貫通孔9a、9b、9c及び9dを備える。本実施形態において、複数の第1貫通孔8及び複数の第2貫通孔9の個数はそれぞれ4であるが、これに限定されず、2個、3個、及び5個以上であってもよい。複数の第1貫通孔8及び複数の第2貫通孔9は、それぞれ互いに対応している。すなわち、第1貫通孔8aと第2貫通孔9aが互いに対応し、第1貫通孔8bと第2貫通孔9bが互いに対応し、第1貫通孔8cと第2貫通孔9cが互いに対応し、第1貫通孔8dと第2貫通孔9dが互いに対応している。「対応する」とは、対応するとされる第1貫通孔8及び第2貫通孔9にピン部材11を挿通可能であることを意味する。
In this embodiment, the first through holes 8 include four first through holes 8a, 8b, 8c, and 8d, and the second through holes 9 include four second through holes 9a, 9b, 9c, and 9d. In this embodiment, the number of the first through holes 8 and the number of the second through holes 9 are four, but this is not limited to four, and the number may be two, three, or five or more. The first through holes 8 and the second through holes 9 correspond to each other. That is, the first through hole 8a and the second through hole 9a correspond to each other, the first through hole 8b and the second through hole 9b correspond to each other, the first through hole 8c and the second through hole 9c correspond to each other, and the first through hole 8d and the second through hole 9d correspond to each other. "Corresponding" means that the pin member 11 can be inserted into the corresponding first through hole 8 and second through hole 9.
本実施形態では、第1貫通孔8cと第2貫通孔9cとに、ピン部材11が挿通して係止されている。ピン部材11は、前後方向に延びる軸部11aと、この軸部11aの前端に設けられた頭部11bと、軸部11aの後端に設けられると共にその間隔を弾性的に変更可能な2つの係止爪11cとを有している。頭部11bは、基部6aの前面に係止され、2つの係止爪11cは、前部5aの下端部の後面に係止されている。ピン部材11の係止により、上方パーツ5と下方パーツ6とは互いに連結され、下方パーツ6に対する上方パーツ5の上下方向の位置が規定されている。なお、本実施形態において、ピン部材11の軸部11aの外径は、第1貫通孔8や第2貫通孔9の内径とほぼ同一であるが、位置決め精度上問題が生じない範囲で、軸部11aの外径が、第1貫通孔8や第2貫通孔9の内径より小さくてもよい。
In this embodiment, a pin member 11 is inserted and engaged into the first through hole 8c and the second through hole 9c. The pin member 11 has a shaft portion 11a extending in the front-to-rear direction, a head portion 11b provided at the front end of the shaft portion 11a, and two engagement claws 11c provided at the rear end of the shaft portion 11a and whose spacing can be elastically changed. The head portion 11b is engaged with the front surface of the base portion 6a, and the two engagement claws 11c are engaged with the rear surface of the lower end portion of the front portion 5a. By engaging the pin member 11, the upper part 5 and the lower part 6 are connected to each other, and the vertical position of the upper part 5 relative to the lower part 6 is determined. In this embodiment, the outer diameter of the shaft portion 11a of the pin member 11 is approximately the same as the inner diameter of the first through hole 8 and the second through hole 9, but the outer diameter of the shaft portion 11a may be smaller than the inner diameter of the first through hole 8 and the second through hole 9 as long as no problems arise in terms of positioning accuracy.
本実施形態では、係止爪11cを備えるピン部材11が用いられているが、これに限定されず、ピン部材11に代えて、ボルト及びナットからなる締結部材を用いてもよいし、第1貫通孔8及び第2貫通孔9のいずれか一方を雌ネジ穴として構成し、当該雌ネジ穴に雄ネジを螺合する構成であってもよい。
In this embodiment, a pin member 11 having a locking claw 11c is used, but this is not limited thereto. Instead of the pin member 11, a fastening member consisting of a bolt and a nut may be used, or one of the first through hole 8 and the second through hole 9 may be configured as a female threaded hole into which a male screw is screwed.
図12(a)に示すように、上方パーツ5に形成された複数の第1貫通孔8は、幅方向(すなわち水平方向)から僅かに傾斜した方向に配列されている。すなわち、第1貫通孔8aは上下方向において第1貫通孔8bの上方に位置し、第1貫通孔8bは上下方向において第1貫通孔8cの上方に位置し、第1貫通孔8cは上下方向において第1貫通孔8dの上方に位置している。本実施形態では、複数の第1貫通孔8のうち、隣り合う2つの第1貫通孔8は、上下方向に一定の距離をあけて配置されている。すなわち、第1貫通孔8aと第1貫通孔8bの間の上下方向の距離h1と、第1貫通孔8bと第1貫通孔8cの間の上下方向の距離h2と、第1貫通孔8cと第1貫通孔8dの間の上下方向の距離h3とが、互いに同等となっている。距離h1、h2及びh3の値は例えば0.5mmであるが、これ以外の値であってもよい。本実施形態の距離h1、h2及びh3の値は同等であるが、互いに異なっていてもよい。
12(a), the multiple first through holes 8 formed in the upper part 5 are arranged in a direction slightly inclined from the width direction (i.e., the horizontal direction). That is, the first through hole 8a is located above the first through hole 8b in the vertical direction, the first through hole 8b is located above the first through hole 8c in the vertical direction, and the first through hole 8c is located above the first through hole 8d in the vertical direction. In this embodiment, among the multiple first through holes 8, two adjacent first through holes 8 are arranged at a certain distance in the vertical direction. That is, the vertical distance h1 between the first through hole 8a and the first through hole 8b, the vertical distance h2 between the first through hole 8b and the first through hole 8c, and the vertical distance h3 between the first through hole 8c and the first through hole 8d are equal to each other. The values of the distances h1, h2, and h3 are, for example, 0.5 mm, but may be other values. In this embodiment, the values of distances h1, h2, and h3 are equal, but may be different from each other.
図12(b)に示すように、下方パーツ6に形成された複数の第2貫通孔9は、幅方向(すなわち水平方向)に配列されている。すなわち、複数の第2貫通孔9a、9b、9c及び9dの上下方向の位置は一定である。このため、複数の第1貫通孔8のうちの隣り合う2つの第1貫通孔8の上下方向の距離は、当該2つの第1貫通孔8に対応する、複数の第2貫通孔9のうちの隣り合う2つの第2貫通孔9の上下方向の距離と異なっている。しかし、このような構成に限定されず、複数の第1貫通孔8と同様に、複数の第2貫通孔9も幅方向(すなわち水平方向)から僅かに傾斜した方向に配列されてもよいが、この場合でも、配列の傾斜角は、第1貫通孔8における配列の傾斜角とは異ならせる必要がある。すなわち、複数の第1貫通孔8のうちの隣り合う2つの第1貫通孔8の上下方向の距離は、当該2つの第1貫通孔8に対応する、複数の第2貫通孔9のうちの隣り合う2つの第2貫通孔9の上下方向の距離と異なっていればよい。
12(b), the second through holes 9 formed in the lower part 6 are arranged in the width direction (i.e., horizontal direction). That is, the vertical positions of the second through holes 9a, 9b, 9c, and 9d are constant. Therefore, the vertical distance between two adjacent first through holes 8 among the first through holes 8 is different from the vertical distance between two adjacent second through holes 9 among the second through holes 9 corresponding to the two first through holes 8. However, this is not limited to such a configuration, and the second through holes 9 may also be arranged in a direction slightly inclined from the width direction (i.e., horizontal direction) like the first through holes 8, but even in this case, the inclination angle of the arrangement needs to be different from the inclination angle of the arrangement of the first through holes 8. That is, the vertical distance between two adjacent first through holes 8 among the first through holes 8 may be different from the vertical distance between two adjacent second through holes 9 among the second through holes 9 corresponding to the two first through holes 8.
複数の第1貫通孔8a、8b、8c及び8dの幅方向の位置と、複数の第2貫通孔9a、9b、9c及び9dの幅方向の位置は、それぞれ同等となっている。
The widthwise positions of the first through holes 8a, 8b, 8c, and 8d are the same as the widthwise positions of the second through holes 9a, 9b, 9c, and 9d.
このような構成において、複数の第1貫通孔8のうちの1つの第1貫通孔8及び複数の第2貫通孔9のうちの1つの第2貫通孔9にピン部材11を挿通して係止すると、下方パーツ6に対する上方パーツ5の上下方向の位置を規定することができる。例えば、第1貫通孔8a及び第2貫通孔9aにピン部材11を挿通した場合は、第1貫通孔8b及び第2貫通孔9bにピン部材11を挿通した場合に比べて、下方パーツ6に対して上方パーツ5を相対的に下方に位置させることができる。すなわち、複数の第1貫通孔8のうちの1つの第1貫通孔8を選択し、複数の第2貫通孔9のうちの1つの第2貫通孔9を選択し、選択した1つの第1貫通孔8と1つの第2貫通孔9にピン部材11を挿通することで、下方パーツ6に対する上方パーツ5の上下方向の位置を調整して規定することができる。
In this configuration, when the pin member 11 is inserted and engaged into one of the first through holes 8 and one of the second through holes 9, the vertical position of the upper part 5 relative to the lower part 6 can be determined. For example, when the pin member 11 is inserted into the first through hole 8a and the second through hole 9a, the upper part 5 can be positioned lower relative to the lower part 6 compared to when the pin member 11 is inserted into the first through hole 8b and the second through hole 9b. In other words, by selecting one of the first through holes 8 among the multiple first through holes 8, selecting one of the second through holes 9 among the multiple second through holes 9, and inserting the pin member 11 into the selected one of the first through holes 8 and one of the second through holes 9, the vertical position of the upper part 5 relative to the lower part 6 can be adjusted and determined.
なお、前記第1実施形態と同様に、本実施形態において、上方パーツ5が仮保持用開口部5a2を備え、下方パーツ6が仮保持爪部6bや支持壁6cを備えていてもよい。
In this embodiment, similar to the first embodiment, the upper part 5 may have a temporary holding opening 5a2, and the lower part 6 may have a temporary holding claw portion 6b and a support wall 6c.
続いて、本実施形態のラジエータグリル1の設計方法について説明する。設計法の説明においても、前記第1実施形態と同等の工程においては、その説明を省略または簡略化する。
まず、前記第1実施形態と同様に、形状仮決定工程S1及び位置関係確認工程S2を実施する。 Next, a method for designing theradiator grille 1 of this embodiment will be described. In the description of the design method, the description of the same steps as those in the first embodiment will be omitted or simplified.
First, similarly to the first embodiment, the shape tentative determination step S1 and the positional relationship confirmation step S2 are carried out.
まず、前記第1実施形態と同様に、形状仮決定工程S1及び位置関係確認工程S2を実施する。 Next, a method for designing the
First, similarly to the first embodiment, the shape tentative determination step S1 and the positional relationship confirmation step S2 are carried out.
次に、位置関係確認工程S2の確認結果に基づいて、ピン部材11を挿通するための、複数の第1貫通孔8から1つの第1貫通孔8を選択すると共に、複数の第2貫通孔9から1つの第2貫通孔9を選択する(高さ調整工程S3)。すなわち、アッパーガーニッシュ102がヘッドライト101に対して適切な上方位置に配置されるような、1つの第1貫通孔8と1つの第2貫通孔9とが選択される。第1貫通孔8と第2貫通孔9の選択においては、ピン部材11をこれらの貫通孔に仮に挿通させてもよいし、ピン部材11の軸部11aと同等の外径を有する棒部材をこれらの貫通孔に挿通して、適切な貫通孔を選択してもよい。
Next, based on the confirmation result of the positional relationship confirmation process S2, one first through hole 8 is selected from the multiple first through holes 8 for inserting the pin member 11, and one second through hole 9 is selected from the multiple second through holes 9 (height adjustment process S3). That is, one first through hole 8 and one second through hole 9 are selected so that the upper garnish 102 is positioned at an appropriate upper position relative to the headlight 101. In selecting the first through hole 8 and the second through hole 9, the pin member 11 may be provisionally inserted into these through holes, or a rod member having an outer diameter equivalent to the shaft portion 11a of the pin member 11 may be inserted into these through holes to select the appropriate through hole.
次に、選択された1つの第1貫通孔8と1つの第2貫通孔9とにピン部材11を挿通して係止する(決定工程S4)。これにより、下方パーツ6に対する上方パーツ5の上下方向の位置が規定され、上方パーツ5に支持されるアッパーガーニッシュ102が、ヘッドライト101に対して適切な上方位置に配置される。
Next, the pin member 11 is inserted into one of the selected first through holes 8 and one of the selected second through holes 9 and engaged (determination step S4). This determines the vertical position of the upper part 5 relative to the lower part 6, and the upper garnish 102 supported by the upper part 5 is positioned at an appropriate upper position relative to the headlight 101.
この時点で本実施形態のラジエータグリル1の設計方法は完了するが、本実施形態のラジエータグリル1において、非選択の第1貫通孔8及び第2貫通孔9にはピン部材11は挿通されず、利用されない。第1貫通孔8及び第2貫通孔9の前方には、第1加飾用パーツ3や第2加飾用パーツ4が設けられるため、車両100の外部から第1貫通孔8及び第2貫通孔9を視認することはできず、大量生産時のラジエータグリル1において非選択の第1貫通孔8及び第2貫通孔9が残されていてもよい。一方、高さ調整工程S3及び決定工程S4の実施により、どの第1貫通孔8及び第2貫通孔9が非選択であるかが明確になるため、非選択の第1貫通孔8及び第2貫通孔9を無くすために、射出成型用の金型を修正してもよい。すなわち、非選択の貫通孔を形成するための、キャビティ内に突出する金型の突部を削って除去してもよい。
At this point, the design method of the radiator grille 1 of this embodiment is completed, but in the radiator grille 1 of this embodiment, the pin member 11 is not inserted into the unselected first through hole 8 and second through hole 9, and they are not used. Since the first decoration part 3 and the second decoration part 4 are provided in front of the first through hole 8 and second through hole 9, the first through hole 8 and second through hole 9 cannot be seen from the outside of the vehicle 100, and the unselected first through hole 8 and second through hole 9 may remain in the radiator grille 1 during mass production. On the other hand, by performing the height adjustment process S3 and the determination process S4, it becomes clear which first through hole 8 and second through hole 9 are unselected, so the injection molding mold may be modified to eliminate the unselected first through hole 8 and second through hole 9. In other words, the protrusions of the mold protruding into the cavity to form the unselected through holes may be removed by grinding.
本実施形態のラジエータグリル1(車両用グリル)は、ヘッドライト101(第1外装部品)の上方に位置するアッパーガーニッシュ102(第2外装部品)を支持し、外部部品103に対して固定される下方パーツ6と、アッパーガーニッシュ102が固定されると共に、少なくとも一部が下方パーツ6の上方に位置し、下方パーツ6に締結された上方パーツ5と、下方パーツ6に対する上方パーツ5の上下方向の位置を規定する高さ規定部10とを備える。
高さ規定部10が、下方パーツ6と上方パーツ5のいずれか一方に形成された複数の第1貫通孔8と、複数の第1貫通孔8にそれぞれ対応して、下方パーツ6と上方パーツ5の他方に形成された複数の第2貫通孔9と、複数の第1貫通孔8のうちの1つの第1貫通孔8と、複数の第2貫通孔9のうちの1つの第2貫通孔9と、に挿通して係止されたピン部材11とを備える。複数の第1貫通孔8のうちの隣り合う2つの第1貫通孔8の上下方向の距離は、当該2つの第1貫通孔8に対応する、複数の第2貫通孔9のうちの隣り合う2つの第2貫通孔9の上下方向の距離と異なる。
複数の第1貫通孔8のうちの隣り合う2つの第1貫通孔8が、上下方向に一定の距離をあけて配置され、複数の第2貫通孔9の上下方向の位置は一定であってもよい。
高さ規定部10が、車両100の幅方向に配列されて複数設けられてもよい。
ラジエータグリル1が、下方パーツ6と上方パーツ5との一方に設けられる仮保持爪部6bと、下方パーツ6と上方パーツ5との他方に設けられると共に仮保持爪部6bを係止可能な仮保持用開口部5a2(被係止部)とを備えてもよい。
ラジエータグリル1が、外部から視認可能な複数の加飾用パーツ3、4を備え、複数の加飾用パーツ3、4は、下方パーツ6に取り付けられてもよい。 The radiator grille 1 (vehicle grille) of this embodiment supports an upper garnish 102 (second exterior part) located above a headlight 101 (first exterior part) and comprises alower part 6 fixed to an external part 103, an upper part 5 to which the upper garnish 102 is fixed and at least a portion of which is located above the lower part 6 and fastened to the lower part 6, and a height determining part 10 which determines the vertical position of the upper part 5 relative to the lower part 6.
Theheight defining portion 10 includes a plurality of first through holes 8 formed in either the lower part 6 or the upper part 5, a plurality of second through holes 9 formed in the other of the lower part 6 or the upper part 5 corresponding to the plurality of first through holes 8, and a pin member 11 inserted into and engaged with one of the plurality of first through holes 8 and one of the plurality of second through holes 9. The vertical distance between two adjacent first through holes 8 of the plurality of first through holes 8 is different from the vertical distance between two adjacent second through holes 9 of the plurality of second through holes 9 corresponding to the two first through holes 8.
Among the plurality of first throughholes 8, two adjacent first through holes 8 may be disposed at a fixed distance in the vertical direction, and the positions of the plurality of second through holes 9 in the vertical direction may be constant.
A plurality ofheight defining portions 10 may be provided and arranged in the width direction of the vehicle 100 .
Theradiator grille 1 may have a temporary holding claw portion 6b provided on one of the lower part 6 and the upper part 5, and a temporary holding opening 5a2 (retained portion) provided on the other of the lower part 6 and the upper part 5 and capable of engaging the temporary holding claw portion 6b.
Theradiator grille 1 includes a plurality of decorative parts 3, 4 that are visible from the outside, and the decorative parts 3, 4 may be attached to a lower part 6.
高さ規定部10が、下方パーツ6と上方パーツ5のいずれか一方に形成された複数の第1貫通孔8と、複数の第1貫通孔8にそれぞれ対応して、下方パーツ6と上方パーツ5の他方に形成された複数の第2貫通孔9と、複数の第1貫通孔8のうちの1つの第1貫通孔8と、複数の第2貫通孔9のうちの1つの第2貫通孔9と、に挿通して係止されたピン部材11とを備える。複数の第1貫通孔8のうちの隣り合う2つの第1貫通孔8の上下方向の距離は、当該2つの第1貫通孔8に対応する、複数の第2貫通孔9のうちの隣り合う2つの第2貫通孔9の上下方向の距離と異なる。
複数の第1貫通孔8のうちの隣り合う2つの第1貫通孔8が、上下方向に一定の距離をあけて配置され、複数の第2貫通孔9の上下方向の位置は一定であってもよい。
高さ規定部10が、車両100の幅方向に配列されて複数設けられてもよい。
ラジエータグリル1が、下方パーツ6と上方パーツ5との一方に設けられる仮保持爪部6bと、下方パーツ6と上方パーツ5との他方に設けられると共に仮保持爪部6bを係止可能な仮保持用開口部5a2(被係止部)とを備えてもよい。
