In addition, the foaming molding of this invention may be comprised with materials other than hard urethane.

  In this embodiment, as shown in FIGS. 1 and 2, the EA material body 2 has a substantially truncated pyramid shape. A clip 20 is provided on the bottom surface of the EA material main body 2 (the surface facing the vehicle body sheet metal 10). The clip 20 is preferably disposed in the vicinity of the center of gravity of the bottom surface of the EA material main body 2 (preferably within a radius of 70 mm or less, particularly 30 mm or less from the center of gravity) when the EA material main body 2 is viewed in plan. In this embodiment, as shown in FIG. 2, the bottom surface of the EA material main body 2 is substantially rectangular when the EA material main body 2 is viewed in plan, and the clip 20 is disposed near the center of the rectangle. ing. The detailed configuration of the clip 20 will be described later. The shape of the EA material main body 2 is not limited to the shape shown in the drawing.

The clip locking hole 11 penetrates the vehicle body sheet metal 10 in the thickness direction. In this embodiment, only one clip locking hole 11 is provided at the center of the EA material mounting area of the vehicle body sheet metal 10. In FIG. 1, the vehicle body sheet metal 10 has a strip shape having a width substantially equal to that of the EA material body 2, but the shape of the vehicle body sheet metal 10 is not limited to this. In this embodiment, the clip locking hole 11 includes a substantially circular opening, but the shape of the clip locking hole 11 is not limited to this.

  In this embodiment, convex portions 12 as positioning means for the EA material 1 are provided on both sides of the EA material mounting region of the vehicle body sheet metal 10. The interval between the protrusions 12 is equal to or slightly more than the width of the bottom surface of the EA material body 2 in the direction connecting these (hereinafter referred to as the width direction of the bottom surface of the EA material body 2) (preferably 0.1 to 0.1). 4 mm, especially about 0.1 to 2 mm). In this embodiment, each convex portion 12 has a tongue-like portion formed on the side edges on both sides of the body sheet metal 10 from the vicinity of the base end of the body sheet metal 10 on the EA material mounting surface side (hereinafter referred to as the front side). It is formed by bending. However, the formation method of each convex part 12 is not limited to this. As shown in FIGS. 2 and 3 (a), when the clip 20 is inserted into the clip locking hole 11 and the EA material 1 is installed in the EA material mounting region of the vehicle body sheet metal 10, the EA material body 2 Each convex part 12 opposes a pair of side surfaces which face each other. As shown in FIG. 2, in a state where the body sheet metal 10 is viewed in plan, the facing surface of each convex portion 12 with the EA material body 2 is substantially parallel to each side surface of the EA material body 2 that faces each other. It is extended.

As shown in FIG. 2, in a state where the vehicle body sheet metal 10 is viewed in plan, the width W ₁ of the facing surface of each convex portion 12 to the EA material body 2 is preferably 3 mm or more, particularly 10 mm or more. When the width W ₁ is less than 3 mm, when the EA material body 2 is in contact with the convex portion 12 by the vibration or the like during the vehicle running, locally excessive load on the EA material body 2 from the protrusions 12 May be added. There is no particular restriction on the upper limit of the width W _1, the width W ₁ may be larger or equal than the width W ₂ of each side of the EA material body 2 in which each convex portion 12 is facing. In this embodiment, as shown in FIG. 2, in a state in which the body sheet metal 10 is viewed in plan, each convex portion 12 is arranged on one end side from the middle in the width direction of each side surface of the EA material main body 2 facing each other. However, the arrangement of the convex portions 12 is not limited to this. For example, each convex part 12 may be arrange | positioned in the middle vicinity of the width direction of each side surface of the EA material main body 2 which each opposes. Alternatively, the width W ₁ of each convex portion 12 and equal to or more than the width W ₂ of each side of the EA material body 2 as described above, the convex portions 12 over substantially the entire width direction of each side of the EA member body 2 You may comprise so that it may confront. In this embodiment, the protrusions 12 are arranged so as to face each other with the EA material main body 2 interposed therebetween, but may not face each other.

  As shown in FIG. 3 (b), at least the base end side of each convex portion 12 facing the EA material main body 2 is curved so as to be closer to the front surface of the body sheet metal 10 toward the EA material main body 2 side. Thus, a curved surface smoothly connected to the front surface of the vehicle body sheet metal 10 is formed. The convex corners of the bottom surface and the side surface of the EA material main body 2 are in contact with the curved surface on the proximal end side of the convex portion 12. The curvature radius R (FIG. 3 (b)) of the curved surface on the proximal end side of the convex portion 12 is preferably 2 to 50 mm, particularly 10 to 20 mm. The protruding height of each convex portion 12 from the front surface of the vehicle body sheet metal 10 is preferably 5 to 50 mm, particularly 10 to 30 mm.

  Each convex portion 12 is formed so that the end portion of the sheet metal on the leading end side (the leading end side in the protruding direction from the front surface of the vehicle body sheet metal 10; the same applies hereinafter) does not contact the EA material body 2. preferable. If the end portion of the sheet metal on the tip side of each convex portion 12 contacts the outer surface of the EA material main body 2, the outer surface of the EA material main body 2 is scraped by the edge (corner edge) of the end portion, and the EA material main body 2 is deformed. Or it may be damaged. In particular, when the EA material body 2 is made of hard urethane, this breakage is likely to occur. In this embodiment, as shown in FIGS. 3 (a) and 3 (b), each convex portion 12 stands up at a substantially right angle to the front surface of the vehicle body sheet metal 10, but each of the EA material main bodies 2 facing each other. Since the side surface is inclined so as to be separated from each convex portion 12 toward the upper side, the end portion of the sheet metal on the tip side of each convex portion 12 does not contact the outer surface of the EA material main body 2. For example, if each side surface of the EA material main body 2 facing each convex portion 12 is substantially perpendicular to the front surface of the vehicle body sheet metal 10, each convex portion 12 is separated from the EA material main body 2 toward the front end side. Thus, it is preferable to stand up obliquely with respect to the front surface of the body sheet metal 10 or to bend the tip side of each convex portion 12 to the opposite side to the EA material body 2 so as not to contact the outer surface of the EA material body 2. .

  Next, the configuration of the clip 20 will be described with reference to FIGS. In this embodiment, the clip 20 is the same as that disclosed in the aforementioned Japanese Patent Application Laid-Open No. 2007-161109.

  The clip 20 is made of an integrally molded product of synthetic resin. As shown in FIGS. 4 and 5, the clip 20 includes a flange 21 disposed along the bottom surface of the EA material body 2, a shaft portion 22 projecting from the flange 21 toward the EA material body 2, and the shaft 20. Expanded from the tip of the portion 22, the anchor 23 embedded in the EA material main body 2, the notch 24 provided in the anchor 23, and the flange 21 project from the opposite side to the shaft portion 22. The locking body 30 is provided.

  The locking body 30 has a cylindrical rising body 31 that stands up from the flange 21, and a locking piece 32 that protrudes laterally from the side surface of the rising body 31 and that can elastically advance and retract in the protruding direction. Have

  The locking piece 32 extends in a direction parallel to the rising direction of the rising body 31. The middle part of the extending direction of the locking piece 32 is the most convex part 40 projecting to the most side, and the tip side of the raised body 31 from the most convex part 40 is the projecting direction toward the tip side. The first slope 41 becomes smaller, and the flange 21 side of the most convex portion 40 becomes the second slope 42 whose height in the projecting direction becomes smaller as the flange 21 side. Yes.

  The cross angle between the first inclined surface 41 and the cylinder axis direction of the raised solid 31 is preferably about 15 to 25 °, and the intersection angle between the second inclined surface 42 and the cylinder axis direction of the raised solid 31 is About 20 to 30 ° is preferable.

  The most flange 21 side of the locking piece 32 is an end face 32 e parallel to the flange 21. The distance (interval) between the end face 32e and the flange 21 is preferably about 1 to 5 mm.

  Two openings 33 extending in the direction parallel to the cylinder axis direction are provided on the side surface of the cylindrical raised body 31. Each locking piece 32 is elastically connected to a portion on the opposite side of the flange 21 among the edges of the openings 33, 33.

  In this embodiment, the opening body 32 is provided with two openings 33 and locking pieces 32 facing each other in the diametrical direction, but three or more openings are spaced apart in the circumferential direction of the body body 31. 33 and the locking piece 32 may be provided. The number of the locking pieces 32 is practically about 2 to 4.

  The tip of the raising body 31 is tapered. In this embodiment, the cylindrical raised body 31 has a cylindrical outer peripheral surface, but since the inner hole has a cross shape, four protrusions 35 protrude from the tip of the raised body 31.

  As shown in FIG. 4, the clip 20 has the shaft portion 22 and the anchor 23 made of the EA material so that the flange 21 is disposed along the bottom surface of the EA material body 2 and the locking body 30 protrudes from the EA material body 2. It is embedded in the main body 2.

  Although detailed illustration is omitted, when the EA material body 2 is foam-molded with a mold, the locking body 30 of the clip 20 is inserted into the clip holding hole provided on the inner surface of the mold, and the flange 21 overlaps the inner surface of the mold. The clip is set on the inner surface of the mold so that the shaft portion 22 and the anchor 23 are exposed in the cavity, and foam molding is performed. Thereby, the EA material 1 provided with the EA material main body 2 and the clip 20 integrated with the EA material main body 2 is manufactured.

  Since the anchor 23 of the clip 20 is provided with the notch 24, a resin such as urethane sufficiently enters between the flange 21 and the anchor 23, and the clip 20 is firmly integrated with the EA material.

  In attaching the EA material 1 to the vehicle body sheet metal 10, the EA material main body 2 is disposed between the convex portions 12, and the leading end side of the raised body 31 of the clip 20 is inserted into the clip locking hole 11, thereby EA. The material body 2 is pressed against the body sheet metal 10. The raised body 31 has a tapered tip, and the protrusion 35 protrudes from the distal end. Therefore, the raised body 31 can be easily inserted into the clip locking hole 11. In addition, since the clip locking hole 11 can be searched for by the protrusion 35, the clip locking hole 11 can be quickly found even in the work of work, and the workability is high.

  When the raised body 31 is inserted into the clip locking hole 11, the first slope 41 of each locking piece 32 of the clip 20 hits the inner peripheral edge of the clip locking hole 11. Then, as the raised solid 31 is pushed into the clip locking hole 11, each locking piece 32 moves backward in the diameter reducing direction of the raised solid 31 and passes through the clip locking hole 11. When the most convex portion 40 passes through the clip locking hole 11, the locking piece 32 elastically returns to its original shape and expands in the diameter increasing direction of the raised body 31, so that the second inclined surface 42 is clipped. It engages with the edge of the stop hole 11 opposite to the EA material body 2. Accordingly, the clip 20 is locked in the clip locking hole 11, and the EA material 1 is attached to the vehicle body sheet metal 10 via the clip 20.

  At this time, the second inclined surface 42 is formed on the edge of the clip locking hole 11 opposite to the EA material main body 2 due to the force that the locking piece 32 elastically expands in the diameter increasing direction of the raised body 31. Pressed. Since the second inclined surface 42 is inclined so that the height in the protruding direction becomes smaller toward the EA material main body 2 side, the clip 20 has the clip locking hole 11 to the side opposite to the EA material main body 2. The force to get out acts. As a result, the EA material body 2 is attracted to the body sheet metal 10 side by the clip 20, and the EA material body 2 comes into close contact with the front surface of the body sheet metal 10. Further, in this way, the EA material body 2 side of the locking piece 32 is the second inclined surface 42 that is inclined so that the height in the protruding direction becomes smaller toward the EA material body 2 side. Therefore, even when the thickness of the vehicle body sheet metal 10 is relatively small or when the thickness of the vehicle body sheet metal 10 is relatively large, the edge of the clip engagement hole 11 opposite to the EA material body 2 is the second edge. The EA material 1 is firmly held by the vehicle body sheet metal 10 as long as it hits the slope 42 of the vehicle body.

  In this structure for attaching the EA material 1 to the vehicle body metal plate 10, the EA material body 2 is attached to the vehicle body metal plate 10 by only one clip 20, but a pair protruding from the vehicle body metal plate 10. Since the convex portions 12 of the EA material body 2 face each other on a pair of opposing side surfaces of the EA material main body 2, even if the EA material main body 2 tries to rotate around the clip 20 due to vibration during vehicle traveling, Each convex part 12 contacts the side surface of the EA material main body 2 to prevent the EA material main body 2 from rotating. Thereby, even if only one clip 20 is provided on the EA material 1, the EA material body 2 can be attached to the vehicle body metal plate 10 with high accuracy. Moreover, since the EA material main body 2 is supported by the clip 20 and each convex part 12, the load applied to these from the EA material main body 2 is disperse | distributed, and the load applied to the clip 20 by vibration etc. is also reduced.

  As described above, in this EA material mounting structure, one clip 20 for mounting the EA material body 2 to the vehicle body sheet metal 10 is sufficient, and there is no need to provide a plurality of clips 20. Thereby, it becomes possible to reduce the manufacturing cost of the EA material 1 and simplify the manufacturing process.

  In this embodiment, the base end side of the facing surface of each convex portion 12 to the EA material body 2 is curved so as to be closer to the EA material body 2 side as it approaches the front surface of the body sheet metal 10. 10 is a curved surface smoothly connected to the front surface, and the convex corners of the bottom surface and the side surface of the EA material main body 2 are in contact with the curved surface. Further, each convex portion 12 is formed so that the end portion of the sheet metal on the tip side does not contact the EA material main body 2. Therefore, even if the EA material main body 2 abuts on each convex portion 12, it is possible to prevent an excessive load from being locally applied from each convex portion 12 to the EA material main body 2. Thereby, even if the EA material main body 2 repeatedly contacts the convex portions 12 due to vibration or the like during traveling of the vehicle, the EA material main body 2 is prevented from being deformed or damaged, so that the EA material main body 2 has high durability. It becomes. Further, rattling of the EA material body 2 is also prevented over a long period of time.

  In addition, by forming each convex portion 12 so that the base end side of the facing surface of each convex portion 12 to the EA material body 2 is a curved surface smoothly connected to the front surface of the vehicle body sheet metal 10, for example, each convex portion Compared with the case in which each convex portion 12 is formed so that the base end side of the facing surface of the portion 12 facing the EA material body 2 intersects the front surface of the vehicle body sheet metal 10 at a right angle, the processing accuracy is eased and simpler processing is possible. Since each convex part 12A can be formed by the method, it is possible to facilitate the machining operation and simplify the processing equipment for forming this convex part 12A. Further, in this embodiment, tongue-like portions are formed on the side edges on both sides of the vehicle body sheet metal 10, and each protrusion 12 is formed by bending them on the front side of the vehicle body sheet metal 10. Therefore, when the body sheet metal 10 is formed by press molding or the like, each convex portion 12 can be formed simultaneously (that is, in one process), and the manufacturing work of the body sheet metal 10 having the convex portion 12 is facilitated. Is possible.

  In this EA material mounting structure, the body sheet metal 10 is provided with the convex portion 12 for positioning the EA material main body 2, but conversely, the EA material main body 2 is provided with the convex portion 12, It is also conceivable that the EA material body 2 is positioned by engaging the convex portion 12 of the EA material body 2 with the vehicle body sheet metal 10. However, in general, foamed synthetic resin such as rigid urethane foam constituting the EA material main body 2 is a brittle material compared to the vehicle body sheet metal 10, so that the convex portion 12 is provided on the EA material main body 2 to form the body sheet metal 10. When engaged, the convex portion 12 is easily worn or damaged by contact with the vehicle body sheet metal 10 and has poor durability. Therefore, it is desirable that the convex portion 12 is provided on the vehicle body sheet metal 10.

[Second Embodiment]
FIG. 9 is an exploded perspective view of the attachment structure of the EA material 1 to the vehicle body sheet metal 10 as the attachment structure of the foam molded member according to the second embodiment, and FIG. 10 is a plan view of the attachment structure. FIG. 11A is a sectional view taken along the line XI-XI in FIG. 9, and FIG. 11B is an enlarged view of a portion B in FIG.

  The convex portion 12 in the first embodiment described above is formed by bending the tongue-like portions formed on the side edges on both sides of the body sheet metal 10 to the front side of the body sheet metal 10 respectively. The convex portion 12A in this embodiment is formed by causing both side portions of the EA material mounting region of the vehicle body metal plate 10 to bulge to the front side of the vehicle body metal plate 10 by extrusion processing such as press molding. Each convex portion 12 </ b> A is formed at a position separated from both side edges of the vehicle body sheet metal 10.

  Also in this embodiment, the convex portions 12A are arranged with an interval equal to or slightly larger than the width of the bottom surface of the EA material main body 2 in the direction connecting them. In this embodiment, each convex portion 12A has a substantially rectangular parallelepiped shape extending in a direction substantially parallel to each side surface of the EA material main body 2 facing each other. Also in this embodiment, as shown in FIG. 11 (b), the proximal end side of the facing surface of each convex portion 12 </ b> A with the EA material body 2 is closer to the EA material body 2 side as it approaches the front surface of the vehicle body sheet metal 10. The curved surface is curved so as to be smoothly connected to the front surface of the vehicle body sheet metal 10, and the convex corner portions of the bottom surface and the side surface of the EA material main body 2 are in contact with the curved surface. The curvature radius R (FIG. 11 (b)) of the curved surface on the proximal end side of the convex portion 12A is preferably 2 to 50 mm, particularly 10 to 20 mm. The protruding height of each convex portion 12A from the front surface of the vehicle body sheet metal 10 is preferably 5 to 50 mm, particularly 10 to 30 mm.

  In this embodiment, the front end side of each convex portion 12A facing the EA material main body 2 is curved so as to separate from the EA material main body 2 toward the front end side, and smoothly on the front end surface of each convex portion 12A. It is a continuous curved surface. The radius of curvature R ′ (FIG. 11B) of the curved surface on the distal end side of the convex portion 12A is preferably 2 to 50 mm, particularly 5 to 30 mm.

  The other configuration of this embodiment is the same as that of the first embodiment described above. In FIGS. 9 to 11, the same reference numerals as those in FIGS. 1 to 8 denote the same parts. The preferable specification value of each convex part 12A other than the above is the same as that of each convex part 12 in 1st Embodiment.

  Even in this embodiment, the EA material main body 2 is attached to the vehicle body sheet metal 10 by only one clip 20, but the pair of convex portions 12A protruding from the vehicle body sheet metal 10 has the EA material. Since the EA material main body 2 tries to rotate around the clip 20 due to vibrations or the like when the vehicle travels, each convex portion 12A remains at the EA material main body because it faces the pair of opposing side surfaces of the main body 2. The EA material main body 2 is prevented from rotating by coming into contact with the side surface of the EA. Thereby, even if only one clip 20 is provided on the EA material 1, the EA material body 2 can be attached to the vehicle body metal plate 10 with high accuracy. Moreover, since the EA material main body 2 is supported by the clip 20 and each convex part 12A, the load applied to these from the EA material main body 2 is disperse | distributed, and the load applied to the clip 20 by vibration etc. is also reduced. Therefore, even in this embodiment, only one clip 20 for attaching the EA material body 2 to the vehicle body sheet metal 10 is sufficient, and there is no need to provide a plurality of clips 20. Thereby, it is possible to reduce the manufacturing cost of the EA material 1 and simplify the manufacturing process.

  Also in this embodiment, the base end side of the facing surface of each convex portion 12A with the EA material main body 2 is curved so as to be closer to the EA material main body 2 side as the front surface of the vehicle body metal plate 10 is approached. 10 is a curved surface smoothly connected to the front surface, and the convex corners of the bottom surface and the side surface of the EA material main body 2 are in contact with the curved surface. Moreover, in this embodiment, each convex part 12A is formed by bulging the part separated from the side edge of the both sides of the body metal plate 10 to the front side of the body metal plate 10 by extrusion processing. Therefore, the end portion of the sheet metal does not exist on the surface of each convex portion 12 </ b> A facing the EA material body 2. Furthermore, in this embodiment, the front end side of the facing surface of each convex portion 12A with the EA material main body 2 is a curved surface that is curved so as to be farther from the EA material main body 2 toward the front end side. Therefore, even if the EA material main body 2 comes into contact with each convex portion 12A due to vibration or the like during traveling of the vehicle, it is possible to prevent an excessive load from being applied locally to the EA material main body 2 from each convex portion 12A. Thereby, even if the EA material main body 2 repeatedly comes into contact with each convex portion 12A, the deformation and breakage of the EA material main body 2 are prevented, so that the durability of the EA material main body 2 becomes high. Further, rattling of the EA material body 2 is also prevented over a long period of time.

  In this way, the base end side of the facing surface of each convex portion 12A with the EA material main body 2 is a curved surface smoothly connected to the front surface of the vehicle body sheet metal 10, and the front end side of this facing surface is the front end surface of each convex portion 12A. By forming the convex portions 12A so as to form curved surfaces that are smoothly connected to each other, the processing accuracy is reduced as compared with the case where the convex portions 12A are formed so that these surfaces intersect at right angles, for example. Since each convex part 12A can be formed by a simpler processing method, it is possible to facilitate the processing work for forming this convex part 12A and simplify the processing equipment. In the embodiment, each convex portion 12A is formed by extruding the body sheet metal 10 by press molding or the like. Therefore, when the body sheet metal 10 is molded by press molding or the like, each projection 12A is also simultaneously formed. It can be formed (in one step), and the manufacturing work of the vehicle body sheet metal 10 having the convex portions 12A can be facilitated.

Are formed with a pair of recesses 3 for receiving the respective protrusions 12A. In this embodiment, each concave portion 3 is formed so as to partially cut out a convex corner portion between the bottom surface of the EA material main body 2 and each side surface facing each convex portion 12A. As shown in FIGS. 13 (a) and 13 (b), the inner surface shape of each recess 3 is substantially the same as the outer surface shape of each protrusion 12A on the EA material body 2 side. That is, in this embodiment, when the EA material 1 is attached to the vehicle body sheet metal 10, each convex portion 12A engages with each concave portion 3 of the EA material main body 2, and each convex portion 12A corresponds to each concave portion 3. Confront the inside.

  The other configuration of this embodiment is the same as that of the second embodiment described above. In FIGS. 12 and 13, the same reference numerals as those in FIGS. 9 to 11 denote the same parts.

  In this embodiment, since each convex part 12A is engaged with each concave part 3 formed in the EA material main body 2, the positioning accuracy of the EA material main body 2 is improved.

  As described above, the base end side of the facing surface of each convex portion 12 </ b> A with the EA material body 2 is curved so as to be closer to the EA material body 2 side as it approaches the front surface of the body sheet metal 10. 10 is a curved surface that is smoothly connected to the front surface of 10, and the distal end side of the opposing surface is a curved surface that is curved so as to be separated from the EA material body 2. Therefore, even if each convex portion 12 </ b> A contacts the inner surface of each recess 3, it is possible to prevent an excessive load from being applied locally to the inner surface of each recess 3. Thereby, even if each convex part 12A repeatedly contacts the inner surface of each concave part 3 due to vibration or the like during traveling of the vehicle, the inner surface of each concave part 3 is prevented from being deformed or damaged. In addition, the EA material body 2 is prevented from rattling over a long period of time.
