Description

  The present invention relates to a structure of a food mall that is attached to a hood of a vehicle.

  For example, as shown in FIG. 5, a hood 3 that covers an upper surface of an engine room in which an engine or the like is accommodated is attached to the front portion of the vehicle 1 so as to be openable and closable.

  In order to reduce damage to a pedestrian or the like at the time of a hood collision as much as possible, for example, in Patent Document 1, the hood hinge portion in front of the hood 3 is deformed by the deformation of the hood 3 at the time of the collision. In order to prevent the shaft portion tip of the bolt 7 to be fastened from becoming an outward projection, the shaft portion tip of the bolt 7 is surrounded by a lid-like portion 6h as shown in FIG. It has been proposed.

JP 2009-190581 A

  Recently, as shown in FIG. 5, a hood 3 is sometimes attached to a hood 3 from the viewpoint of design (design), and the hood 3 is made of resin. The mainstream is a structure integrally formed by the above.

  Here, when it is desired to extend the food mall 2 in the longitudinal direction (in the vehicle width direction in FIG. 5) in order to respond to a request for a design (design) change, etc. It is assumed that it is difficult to obtain satisfactory quality, for example, undulation or the like is generated on the surface from the aspect of rigidity, etc. and the appearance is deteriorated.

  In such a case, after the food molding is divided into a plurality of pieces in the thickness direction and then molded, the plurality of molded products are assembled by a method such as fastening while interposing a bracket or the like. By adopting a food mall structure, it is now possible to provide a good-looking food mall with improved surface undulations.

  An example of the divided food mall structure as described above is shown in FIG. 4. In such a divided food mall structure, the front side food mall 20 disposed on the front side and the hood 3 (vehicle) side are provided. The vehicle-side hood molding 30 on the side to be attached is fastened by a screw 50 via a bracket 40.

  In the divided food molding structure having such a configuration, the conventional resin-molded food molding structure is not a problem. However, the shaft of the screw 50 is deformed by the deformation of the hood 3 at the time of collision. It is necessary from the viewpoint of pedestrian protection (from the viewpoint of reducing damage to a pedestrian or the like at the time of a collision) to prevent the front end 51 from being an outward projection.

  From such a point of view, referring to the technique shown in FIG. 6, for example, as shown in FIG. 4, the shaft portion tip 51 of the screw 50 is surrounded by a lid-like portion 60 such as a protective cap. It can be envisaged.

However, it is assumed that a sufficient space (for example, the gap H in FIG. 4) in which the lid-like portion 60 is disposed cannot be secured.
Furthermore, since the lid-like member 60, which is a separate member, is attached to the back side of the front-side food molding 20, the number of parts increases and access to the lid-like member 60 is difficult, and the number of assembly steps increases. There is a risk that it may be difficult to keep product costs low.

  The present invention has been made in view of such circumstances, and has a simple and low-cost configuration, and in a split type food mall in which a plurality of parts are integrally configured by fastening or the like, surface undulation is suppressed and looks good. An object of the present invention is to provide a food mall that can provide a good appearance and can reduce damage to a pedestrian or the like at the time of a collision and is excellent in protection of the pedestrian or the like.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the accompanying drawings. The present invention is not limited to the embodiments described below.

  As shown in FIG. 1, a split hood molding 100 according to an embodiment of the present invention includes a front side hood molding 120 disposed on the front side (outer side) of the vehicle and a vehicle side hood attached to the vehicle side. A molding 130 and a bracket 140 are included.

  The front side hood molding 120 can be made of a resin such as ABS resin having a relatively low rigidity, and the vehicle side hood molding 130 can be made of a resin such as PP (polypropylene) having a relatively high rigidity. .

  The bracket 140 can be formed of a metal material such as aluminum, iron, or titanium, a resin material having relatively high rigidity, or a composite material of carbon fiber or the like and a resin material (plastic).

  The decorative resin hood molding 160 may be attached to the front side of the front hood molding 120 by fitting engagement or the like so as to cover the front hood molding 120.

  As shown in FIG. 2, the vehicle-side hood molding 130 is attached to the front end portion of a hood 110 (engine hood or trunk hood) attached to the front portion of the vehicle so as to be openable and closable by a conventional technique.

  For example, the vehicle-side hood molding 130 can be attached to the vehicle-side hood 110 by a conventional method such as engagement with a double-sided tape, a clip, or the like, or fastening with a screw or the like.

  In this embodiment, as shown in FIGS. 1 and 2, the vehicle-side hood molding 130 is screwed on the vehicle side (inside) near both ends of the front-side hood molding 120 with the bracket 140 interposed therebetween. 150 is fixed.

  For example, the screw 150 is screwed into a screwing hole 155A of a rectangular case nut 155 that is inserted and fixed so as to be prevented from turning to the front side food molding 120 side.

  The case nut 155 can be constituted by a folded metal plate, for example, as shown in FIGS. 1 to 3, and the folded metal plate has a screwing hole 155 </ b> A that can be screwed with the screw 150. 1 and 3, the open end side of the folded metal plate is bridged from the lateral side (longitudinal direction of the front side food molding 120) as shown in FIGS. By attaching so as to sandwich the rib portion 121, the screw 150 is attached so as to be able to prevent rotation when the screw 150 is screwed into the screw fixing hole 155A. A hole for allowing the screw 150 to pass through is opened in the rib portion 121 of the front side food molding 120.

In this way, by attaching the bracket 140 having higher rigidity than the front surface food molding 120 made of resin such as ABS between the front side food molding 120 and the vehicle side food molding 130, Rigidity in the vicinity of both ends is increased, so that the occurrence of waviness on the surface is suppressed, contributing to improvement in appearance.
That is, the bracket 140 functions as a reinforcing member (reinforcing plate) and corresponds to an example of the bracket according to the present invention.

  As shown in FIG. 1, the portion of the front side hood molding 120 where the bracket 140 is attached at both ends and the rigidity is increased is not attached to the vehicle side hood molding 130 via the mounting bolt 170. It is done.

  As shown in FIG. 1, the mounting bolt 170 is attached by attaching its rectangular head 171 to the rib portion 122 of the front side food molding 120 from the lateral direction (longitudinal direction of the front side food molding 120). Thus, when the nut 180 is fastened to the mounting bolt 170, the rotation is stopped.

  The mounting bolt 170 attached to the rib portion 122 of the front side food molding 120 is inserted into the bolt hole 132 provided in the rib portion 131 of the vehicle side food molding 130 and then fastened and fixed by the nut 180. In addition, the surface side food molding 120 side of the head of the mounting | wearing bolt 170 can be formed flat.

  Also, similar mounting bolts 170 are mounted on the rib portions 123 near both ends of the front side food molding 120, and the mounting bolts 170 near both ends are respectively inserted into the bolt holes 141 provided in the bracket 140. The nut is inserted and fixed by a nut 180.

  In this way, the front side food molding 120 and the bracket 140 are fastened to the vehicle side food molding 130 by the screw 150 and the mounting bolt 170, so that the front side food molding 120 and the vehicle side food molding 130 are substantially omitted. It is integrated and attached to the hood 110 of the vehicle.

  Even when a relatively long food molding is adopted and a soft surface side food molding 120 having a relatively low rigidity as in the present embodiment is adopted, both ends thereof are relatively rigid. Since the bending rigidity and the torsional rigidity can be ensured by attaching to the vehicle-side hood molding 130 via the high bracket 140, it is possible to provide an appearance that suppresses the undulation of the surface and the like and has a good appearance.

  Here, in the present embodiment, the shaft tip 151 of the screw 150 is prevented from becoming an outward projection due to deformation of the hood 110 or the front side hood molding 120 at the time of collision. It is comprised so that damage to a pedestrian etc. can be reduced.

  Specifically, a protrusion restraining rib 200A that protrudes in the same direction as the distal end side of the shaft portion distal end 151 of the screw 150 from the rib portion 121 of the front side food molding 120 to which the case nut 155 to which the screw 150 is screwed is attached. , 200B are formed integrally with the rib portion 121 on both sides of the case nut 155 of the rib portion 121 by, for example, resin molding.

  The rib portion 121 of the front side food molding 120 is a bridge-like shape that once branches from the back side of the front side food molding 120, protrudes toward the vehicle side food molding 130, and merges with the back side of the front side food molding 120 again. It has a portion.

  By the way, the protrusion restraining ribs 200A and 200B can be integrally formed with the rib portion 121 and the surface side food molding 120, but after being formed separately, they are integrally attached by a method such as adhesion and engagement. It is also possible to have a typical configuration.

  Further, as shown in FIGS. 2 and 3, the protrusion suppression ribs 200 </ b> A and 200 </ b> B are disposed on both sides of the case nut 155 in the vertical direction, so that the function of the case nut 155 as a detent when the screw 150 is fastened. Can be combined.

  In this manner, the protrusion suppression ribs 200A and 200B extend along the width direction of the rib portion 121 of the front surface side food molding 120 (longitudinal direction of the front surface side food molding 120) and on both sides in the vertical direction of the case nut 155. Thus, the protrusion restraining ribs 200A and 200B are present in the vicinity of the shaft portion tip 151 of the screw 150 to be screwed with the case nut 155. Therefore, as shown in FIG. Even when 120 is deformed, it is possible to effectively prevent the tip of the shaft portion tip 151 of the screw 150 from protruding outward.

  The height of the protrusion restraining ribs 200A and 200B (the amount of protrusion of the rib portion 121 from the vehicle outer surface) is larger than the amount of protrusion of the shaft portion tip 151 of the screw 150. It is preferable from the viewpoint.

  On the other hand, from the viewpoint of appearance from the outside of the front surface side food molding 120, the inside (back surface) of the front side food molding 120 and the protrusion suppression rib in a state where no deformation due to collision or the like has occurred (normal time). It is preferable that there is a gap A between the tips of 200A and 200B. For example, if the inner side (back surface) of the front surface side food molding 120 and the tip of the protrusion suppression rib 200 are brought into contact (contact), the front ends of the protrusion suppression ribs 200A and 200B press the front surface side food molding 120. The slight deformation caused by this will appear as irregularities on the surface of the front side food molding 120 when viewed from the front side of the front side food molding 120 and deteriorate the appearance, but the gap A is provided. Thus, such a phenomenon can be avoided.

  In addition, when the inner side (back surface) of the front surface side food molding 120 and the tip of the protrusion suppression rib 200 are integrally formed during resin molding so as to be continuous, the resin flow cannot be made uniform. When viewed from the front side of the front side food molding 120, it appears as irregularities on the surface of the front side food molding 120 and deteriorates the appearance. However, the gap A is provided, and the inner side (back side) of the front side food molding 120 Such a phenomenon can be avoided by separating the protrusion prevention rib 200 from the tip.

  In the present embodiment, the case where the protrusion suppression ribs 200A and 200B are provided on both sides of the case nut 155 in the vertical direction (the short axis direction of the front side food molding 120) has been described. However, the present invention is not limited to this. Alternatively, the case nut 155 may be provided on both sides in the left-right direction (the long axis direction of the front side food molding 120).

  As described above, according to the split type food molding 100 according to the present embodiment, in the split type food molding in which a plurality of parts are integrally configured by fastening or the like while having a simple and low-cost configuration, surface undulation is performed. In addition, it is possible to provide an appearance that is suppressed and the appearance is good, and that it is possible to reduce damage to pedestrians and the like during a collision, and to provide a food mall that is excellent in protecting pedestrians and the like.

  In the present embodiment, the case where the case nut 155 is used when the front side hood molding 120, the bracket 140, and the vehicle side hood molding 130 are fastened and fixed by the screw 150 has been described. For example, a metal thin plate (functioning as a nut) can be cast when the front side food molding 120 is molded.

  In the present embodiment, the case where the front side hood molding 120, the bracket 140, and the vehicle side hood molding 130 are fastened and fixed by the screw 150 is described as an example. The present invention is also applicable to the case where only the front side hood molding 120 and the bracket 140 are fastened and fixed to the rib portion 121 by the screw 150 without fastening the molding 130 together.

  That is, according to the present invention, the bracket 140 is disposed on the vehicle-side hood molding 130 side of the surface-side hood molding 120, the screw 150 is branched from the surface-side hood molding 120, protrudes toward the vehicle-side hood molding 130, and again on the surface side. The bracket 140 is fastened and fixed to the rib part 121 of the front side food molding 120 by screwing the rib part 121 joining the food molding 120 from the vehicle side food molding 130 side toward the front side food molding 120 side. Applicable to
