JP 2012-245870 A JP-A-4-283141

  The radiator grille is a resin member extending in the vehicle width direction, and its thickness is reduced in order to reduce the weight. For this reason, the radiator grille may be deformed, for example, bent due to vibration during traveling, and it is difficult to stabilize the shape.

  The headlamp has a transparent lens surface, and if the lens surface is scratched, the light irradiation direction (angle) may be disturbed. The headlamp is supported by the vehicle frame and is fixed in position.

  In Patent Document 1, since the opening of the radiator grille exposes the headlamp, both ends provided with the opening may be deformed to contact the headlamp and damage the lens surface. In Patent Document 2, when the radiator grille is mounted between the headlamps, the fin portion comes into contact with each headlamp, so that the lens surface may be damaged.

  It is also conceivable to provide a cushion member between the headlamp and the radiator grill to prevent the lens surface from being damaged. However, with this measure, the number of parts increases and the manufacturing cost increases as the cushion member is added.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a vehicle radiator grille structure that can prevent the radiator grille from coming into contact with the headlamp during traveling or the like and prevent the headlamp from being damaged.

  In order to solve the above problems, a typical structure of a radiator grille structure for a vehicle according to the present invention is a radiator grille structure for a vehicle including a radiator grille assembled to a front bumper of the vehicle. A resin main body portion that extends, and a first opening that is formed at both ends of the main body portion and exposes the headlamp fixed to the vehicle body, and forms a first gap in the front-rear direction between the headlamp. An opening, a second opening formed in the center of the main body, and a connecting portion attached to the main body from the edge of the first opening to the edge of the second opening to reinforce the main body. And

  According to the above configuration of the present invention, the position of the headlamp fixed to the vehicle body is fixed. On the other hand, the thickness of the main body of the radiator grille is reduced in order to reduce the weight. Further, the radiator grill is made of resin extending in the vehicle width direction. Therefore, although the position of the headlamp is fixed, the radiator grill may be deformed when vibrated. In particular, since both ends of the radiator grill main body provided with the first opening are free ends, they are easily deformed by vibration.

  However, since the radiator grille is reinforced by the connecting portion from the edge of the first opening to the edge of the second opening, both ends of the radiator grille body provided with the first opening are easily deformed. It connects with the 2nd opening which is hard to change. Therefore, the shape of the radiator grill becomes more stable. As a result, the first gap between the first opening and the headlamp is maintained, the radiator grille does not contact the headlamp, and the headlamp can be more reliably prevented from being damaged.

  The connecting portion connects the first end connected to the edge of the first opening, the second end connected to the edge of the second opening, and the first end and the second end. It is good to have the intermediate part spaced apart from the main-body part of a radiator grille. Thereby, when the main body part of the radiator grill is going to be deformed to the rear side of the vehicle, the deformation of the main body part can be further suppressed by stretching the intermediate part separated from the main body part. Therefore, the shape of the radiator grill is more stable and the headlamp can be more reliably prevented from being damaged.

  The radiator grille structure for a vehicle includes a grill cover extending in the vehicle width direction fixed to a vehicle body or a rigid part fixed to the vehicle body, which is installed on the back surface of the main body and exposed through the second opening, and the grill An extension portion extending from both ends of the cover and overlapping the connection portion; and a fixing member for fixing the extension portion to the connection portion. The connection portion protrudes from the intermediate portion toward the extension portion, and the meat to which the fixing member is fixed The extension portion further includes a seat surface that is in contact with the top of the thick portion and to which the fixing member is fixed, and a first end portion of the connecting portion that is continuous from the seat surface and a second gap in the front-rear direction. The second gap is preferably smaller than the first gap.

  Here, after attaching the grill cover to the radiator grill, fixing the extension portion of the grill cover to the coupling portion of the radiator grill by the fixing member, and further assembling the front bumper to the vehicle body to secure the first gap and the second gap Suppose that the radiator grill vibrates during traveling. In such a situation, the position of the headlamp fixed to the vehicle body and the grill cover fixed to the vehicle body or a rigid part fixed to the vehicle body is fixed. On the other hand, the radiator grille is reinforced by the connecting part, and although the connecting part is fixed to the extension part of the grill cover, the first opening is still deformed so as to approach the headlamp due to vibration, and is in contact with the headlamp. There is a risk.

  However, since the second gap is smaller than the first gap, even if the first opening of the radiator grill is deformed, first, the first end of the connecting portion located at the edge of the first opening is first. It will contact the tip of the extension of the grill cover. For this reason, the first opening of the radiator grille is less likely to come into contact with the headlamp, and the headlamp can be more reliably prevented from being damaged. Further, when the grill cover is attached to the radiator grill, the radiator grill can be easily aligned by covering the connecting portion of the radiator grill with the extension portion of the grill cover. Furthermore, since the extension portion includes a seat surface for fixing the fixing member and a tip portion continuous from the seat surface, the fixing member cannot be seen from the outside even through the transparent lens surface of the headlamp, and the appearance is impaired. Absent.

In the following description, the first opening 110 and the connecting portion 116 located in the region A out of the pair of first opening portions 108 and 110 and the pair of connecting portions 114 and 116 will be mainly described. 108 and the connecting portion 114 also have the same configuration.

  The first opening 110 exposes a headlamp lens surface 118 (see FIG. 5), not shown here. As shown in FIG. 3, the connecting portion 116 is integrally formed and attached to the main body portion 106 from the edge 110 a of the first opening portion 110 to the edge 112 a of the second opening portion 112, and reinforces the main body portion 106.

  Further, as shown in FIG. 2, the vehicle radiator grill structure 100 includes a grill cover 120, extensions 122 and 124 extending from both ends of the grill cover 120, fixing members 126 and 128 such as screws, and a garnish 130. Further prepare. The grill cover 120 is a member that is fixed to the vehicle body or a rigid part that is fixed to the vehicle body and extends in the vehicle width direction. The grill cover 120 is installed on the back surface 104a of the main body portion 106 of the radiator grill 104, as shown in FIG. Exposed by the second opening 112.

  Although details will be described later, the extension portions 122 and 124 overlap the connecting portions 114 and 116 in a state where the grill cover 120 is installed on the back surface 104a of the main body portion 106 of the radiator grill 104, respectively. The fixing members 126 and 128 fix the extending portions 122 and 124 to the connecting portions 114 and 116, respectively. The garnish 130 is attached to the grill cover 120 exposed from the second opening 112 from the design surface side (surface side) of the radiator grill 104. In this way, the radiator grille 104 to which the above members are attached is assembled to the upper part of the front bumper 102 as shown in FIG.

  As shown in FIG. 3, the connecting part 116 includes a first end 132 connected to the edge 110 a of the first opening 110, a second end 134 connected to the edge 112 a of the second opening 112, and An intermediate portion 136. The intermediate portion 136 connects the first end portion 132 and the second end portion 134 and is separated from the main body portion 106 of the radiator grill 104, and forms a bridge shape with the first end portion 132 and the second end portion 134. Yes. The intermediate portion 136 is formed with a thick portion (boss 138) to which the fixing member 128 is fixed.

  In the figure, the back surface 130a of the garnish 130 attached to the grill cover 120 is shown. A plurality of claw portions 140 a and 140 b are formed on the back surface 130 a of the garnish 130. A plurality of claw portions 142 a, 142 b, 142 c are formed on the back surface 104 a of the radiator grill 104 along the edge 112 a of the second opening 112.

  FIG. 4 is a view showing a state where the grill cover 120 is installed on the back surface 104a of the radiator grill 104 of FIG. FIG. 4A is a plan view of the back surface 104a of the radiator grill 104 as viewed from the vehicle body side. FIG. 4B is a perspective view of the back surface 104a of the radiator grill 104 viewed from a direction different from that in FIG. FIG. 5 is a cross-sectional view of the vehicle radiator grill structure 100 shown in FIG.

  As shown in FIGS. 4A and 4B, the grill cover 120 has holes 144a, 144b, 146a, 146b, and 146c corresponding to the plurality of claw portions 140a, 140b, 142a, 142b, and 142c. Have each. In the vehicle radiator grill structure 100, a plurality of claw portions 140a, 140b, 142a, 142b, 142c are engaged with the holes 144a, 144b, 146a, 146b, 146c, respectively, and then extended by a fixing member 128. The portion 124 is fixed to the connecting portion 116 having the bridge shape. In this way, the grill cover 120 is attached not only to the radiator grill 104 but also to the garnish 130.

  As shown in FIG. 5, the first opening 110 exposes the headlamp lens surface 118. The headlamp lens surface 118 is supported by the housing 148. The headlamp lens surface 118 and the housing 148 form a headlamp unit 150. The position of the headlamp lens surface 118 is fixed because the housing 148 is supported by a vehicle body frame (not shown).

  On the other hand, the main body portion 106 of the radiator grill 104 is made of resin extending in the vehicle width direction, and the plate thickness thereof is thin in order to reduce the weight. For this reason, the radiator grill 104 may be deformed, for example, by bending due to vibration during traveling. In particular, the end 110b of the first opening 110 is a free end, and only forms a first gap L1 in the front-rear direction with the headlamp lens surface 118 as shown in FIG. Absent.

  That is, if the radiator grill 104 is deformed by vibration and the end portion 110b of the first opening 110 approaches the headlamp lens surface 118 by the first gap L1 or more, the transparent headlamp lens surface 118 may be damaged. is there. If the headlamp lens surface 118 is scratched, the light irradiation direction (angle) may be disturbed.

  Therefore, in the vehicle radiator grill structure 100, a second gap L2 in the front-rear direction having a dimension in the front-rear direction smaller than the first gap L1 is set between the radiator grill 104 and the grill cover 120.

Specifically, as shown in FIG. 5, the extension portion 124 includes a mounting seat surface 152, a side portion 154, and a tip portion 156. The mounting seat surface 152 is a seat surface on which the fixing member 128 is fixed by contacting the top portion 138a of the boss 138 of the connecting portion 116. The mounting seat surface 152 is formed with an insertion hole 152a through which the fixing member 128 is inserted. The boss 138 of the connecting portion 116 is formed with a fixing hole 138b at a position overlapping the insertion hole 152a. The fixing member 128 is screwed and fixed to the fixing hole 138b. The side portion 154 of the extension portion 124 is curved along the boss 138 from the mounting seat surface 152 and extends to the vicinity of the intermediate portion 136 of the connecting portion 116. For example, as illustrated in FIG. 4B, the extension portion 124 has a box shape that covers the coupling portion 116 with the mounting seat surface 152 and the side portion 154.

  The distal end portion 156 is continuous from the side portion 154 and overlaps the first end portion 132 of the connecting portion 116 via the second gap L2. In addition, when the dimension of the 1st gap | interval L1 will become small by component precision or assembly | attachment precision, you may adjust suitably so that the dimension of the 2nd gap | interval L2 may be made still smaller.

  As described above, in the vehicle radiator grill structure 100 according to the present embodiment, since the dimension in the front-rear direction of the second gap L2 is smaller than the first gap L1, the first opening of the radiator grill 104 is caused by vibrations during traveling. Even if the end portion 110 b of the portion 110 is deformed, first, the first end portion 132 of the connecting portion 116 comes into contact with the distal end portion 156 of the extension portion 124 of the grill cover 120.

  That is, even if the end 110b of the first opening 110 is deformed and the second gap L2 becomes narrower and eventually disappears, the first gap L1 is larger than the second gap L2, so that the end 110b does not contact the headlamp lens surface 118.

  Therefore, according to the present embodiment, the end portion 110b of the first opening 110 in the radiator grill 104 is difficult to contact the headlamp lens surface 118, and the headlamp lens surface 118 can be prevented from being damaged. . In addition, since the end 110b of the first opening 110 does not contact the headlamp lens surface 118, the headlamp lens surface 118 remains at an appropriate position even when the radiator grill 104 vibrates. The parting with the surrounding parts, that is, the dimension between the parts is stabilized.

  As described above, the headlamp lens surface 118 is fixed to the vehicle body via the housing 148, and the grill cover 120 is also fixed to the vehicle body or a rigid component fixed to the vehicle body. For this reason, even if the radiator grill 104 vibrates and the end portion 110b of the first opening 110 is deformed, the relative position between the grill cover 120 and the headlamp lens surface 118 does not change. Therefore, even when the radiator grille 104 vibrates, the magnitude relationship between the first gap L1 and the second gap L2 is maintained. First, the first end 132 of the connecting portion 116 is first connected to the extension 124. It will come into contact with the tip 156.

  In the present embodiment, since the connecting portion 116 has a bridge shape including the intermediate portion 136, for example, when the main body portion 106 is about to be deformed on the rear side of the vehicle, the intermediate portion separated from the main body portion 106 of the radiator grill 104. Since the portion 136 is stretched, the deformation of the main body portion 106 can be further suppressed. Therefore, the shape of the radiator grille 104 is more stable, and the headlamp lens surface 118 can be more reliably prevented from being damaged.

  Further, when the grill cover 120 is attached to the radiator grill 104, the coupling portion 116 of the radiator grill 104 is covered with the extension portion 124 of the grill cover 120, so that both can be easily aligned. Further, since the extension portion 124 includes a mounting seat surface 152 that fixes the fixing member 128 and a tip portion 156 that continues from the mounting seat surface 152 via the side portion 154, even through the transparent headlamp lens surface 118, The fixing member 128 cannot be visually recognized from the outside, and the appearance is not impaired.

  In the above embodiment, by setting the second gap L2 whose dimension in the front-rear direction is smaller than the first gap L1, the end portion 110b of the first opening 110 is prevented from contacting the headlamp lens surface 118. However, it is not limited to this. That is, even if the radiator grill 104 vibrates during traveling or the like, if the first gap L1 can be maintained, the second gap L2 is not set and the first of the connecting portion 116 is set. It is good also as interference setting which makes the front-end | tip part 156 of the extension part 124 contact the edge part 132. FIG.

  That is, the radiator grill 104 is reinforced by the connecting portion 116 from the edge 110 a of the first opening 110 to the edge 112 a of the second opening 112. For this reason, the easily deformable end portion 110 b provided with the first opening 110 in the main body portion 106 of the radiator grill 104 is connected to the second opening 112 that is difficult to deform. As a result, as long as the shape of the radiator grill 104 is more stable and the first gap L1 between the first opening 110 and the headlamp lens surface 118 is maintained, the radiator grill 104 does not contact the headlamp lens surface 118. It is possible to prevent the headlamp lens surface 118 from being damaged.

  Further, in the above embodiment, the radiator grill 104 has a bridge shape including the intermediate portion 136 in which the connecting portion 116 is separated from the main body portion 106, but is not limited to this. That is, if the radiator grill 104 is reinforced by the connecting portion 116 from the edge 110a of the first opening 110 to the edge 112a of the second opening 112, the intermediate portion 136 is not separated from the main body portion 106, and the main body portion 106 may overlap.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  INDUSTRIAL APPLICABILITY The present invention can be used for a vehicle radiator grill structure including a radiator grill assembled to a vehicle front bumper.
