(First embodiment)
Hereinafter, a first embodiment of a foam filler will be described with reference to FIGS.
As shown in FIGS. 1 and 2A, the foam filler 11 is attached to the first panel 91. The foam filler 11 has a support member 21 and a foamable member 31 that becomes a foam when heated. Further, the foam filler 11 has a housing member 41 that houses the foamable member 31 and a fixing member 51 that fixes the housing member 41 to the support member 21.

  The support member 21 includes a fixing portion 22 that is fixed to the first panel 91 by welding, and a standing portion 23 that is erected on the fixing portion 22. The fixing portion 22 and the standing portion 23 are made of a metal such as iron or an iron alloy, for example, and both are formed in a plate shape. The overall shape of the support member 21 is L-shaped, and can be easily formed using a metal plate. The standing portion 23 has a pair of through holes 24 and 24 used for fixing the accommodation member 41.

  The support member 21 is arranged so that the interior (hollow part) of the hollow structure formed using the first panel 91 is partitioned by the standing part 23. Such a support member 21 is used for reinforcing a hollow structure, for example.

  The foamable member 31 is heated and foamed and cured to form a foam. The foamable member 31 is obtained by molding a foamable material by a known molding method such as extrusion molding, press molding, or injection molding. The foamable material contains a base material and a foaming agent. The foamable material contains a crosslinking agent, a filler, a plasticizer, and the like as necessary. Examples of the substrate include synthetic resins, elastomers, and rubbers. Examples of the synthetic resin include polyolefin, epoxy resin, phenol resin, urethane resin, acrylic resin, styrene resin, and EVA (ethylene / vinyl acetate copolymer). Examples of the elastomer include RB (polybutadiene elastomer), SBS (styrene / butadiene / styrene block copolymer), SIS (styrene / isoprene / styrene block copolymer), and SEBS (styrene / ethylene / butylene / styrene block copolymer). ). Examples of rubber include NR (natural rubber), SBR (styrene / butadiene rubber), BR (butadiene rubber), NBR (nitrile rubber), CR (chloroprene rubber), IR (isoprene rubber), IIR (butyl rubber), EPDM.

  Examples of the foaming agent include azodicarbonamide and dinitropentamethylenetetramine. Examples of the crosslinking agent include dimethylurea and dicyandiamide. Examples of the filler include calcium carbonate, barium sulfate, ferrite, and silica.

  The housing member 41 includes a wall portion 42 that faces the standing portion 23, and a cover portion 43 that protrudes from the wall portion 42 toward the standing portion 23. The cover portion 43 includes a first side surface cover portion 44, a second side surface cover portion 45, and a bottom surface cover portion 46. The first side surface cover portion 44 and the second side surface cover portion 45 are provided on the wall portion 42 at a predetermined interval, and the first side surface cover portion 44 and the second side surface cover portion 45 are disposed to face each other. The first side surface cover portion 44 and the second side surface cover portion 45 are connected by a bottom surface cover portion 46, and the cover portion 43 is disposed so as to surround the periphery of the wall portion 42.

  The foamable member 31 is disposed inside the cover portion 43. The foamable member 31 is fixed to the housing member 41 using an adhesive, for example. The foamable member 31 can also be fixed by being fitted between the first side surface cover portion 44 and the second side surface cover portion 45. The foamable member 31 can also be fixed to the storage member 41 by providing the storage member 41 with a locking claw that locks the foamable member 31.

  In the foamable member 31 accommodated in the accommodating member 41, the pair of side surfaces are covered with the first side surface cover portion 44 and the second side surface cover portion 45, and the bottom surface located at the proximal end close to the fixing portion 22 is the bottom surface cover portion. 46.

  Here, the foaming direction of the foamable member 31 is regulated by the wall portion 42 facing the standing portion 23. For this reason, the foam comes into contact with the surface of the standing portion 23 that faces the wall portion 42. Thus, the standing part 23 has the contact surface 25 which contacts a foam.

The housing member 41 is made of a material that can withstand heating when the foamable member 31 becomes a foam. The housing member 41 of this embodiment is integrally formed using polyamide.
The fixing member 51 is provided integrally with the housing member 41. That is, the fixing member 51 is integrally formed from the same material as the housing member 41.

  As shown in FIG. 1, the fixing member 51 is inserted into the pedestal portion 52 that can come into contact with the erected portion 23, the insertion portion 53 that is inserted into the through hole 24, and the erected portion 23. And a locking portion 54 to be locked. The locking portion 54 includes a first locking portion 54 a that protrudes from one side surface of the insertion portion 53 and a second locking portion 54 b that protrudes from the other side surface of the insertion portion 53.

  As shown in FIGS. 2A and 2B, the housing member 41 is fixed to the support member 21 by a fixing member 51. As described above, the foamable member 31 positioned by the fixing of the accommodating member 41 is separated from the standing portion 23. The position of the foamable member 31 relative to the standing portion 23 can be set according to the size of the foamable member 31 and the distance between the wall portion 42 and the standing portion 23.

Next, the operation of the foam filler 11 will be described.
As shown in FIGS. 3A and 3B, the foam filler 11 is applied to a hollow structure 93 formed using a first panel 91 and a second panel 92. For example, the first panel 91 is an inner panel of the vehicle, and the second panel 92 is an outer panel of the vehicle.

  First, the foam filler 11 is fixed to the first panel 91 by welding the support member 21 to the first panel 91. As the welding, spot welding is preferably used from the viewpoint of easily increasing the efficiency when the foam filler 11 is attached.

  In such welding, for example, heat generated at an electrode portion or an energized portion or heat of sputtering is generated. When this heat is transmitted to the foamable member 31, the outer surface of the foamable member 31 may be thermally denatured. In this regard, in the foam filler 11 of the present embodiment, at least a part of the foamable member 31 is covered with the cover portion 43. For this reason, the heat generated along with the welding of the fixing portion 22 and the first panel 91 is not easily transmitted to the foamable member 31.

  Subsequently, the hollow structure 93 is formed by joining the first panel 91 and the second panel 92. The hollow structure 93 constitutes a part of the vehicle. Examples of the vehicle include a pillar, a door panel, a roof panel, a trunk lid, a front hood panel, various reinforcements, and the like.

  The vehicle to which the foam filler 11 is attached is subjected to a process (drying process) for baking the coating after the electrodeposition coating. The foamable member 31 starts to foam and harden when heated by the drying process. At this time, since the foamable member 31 is provided between the standing part 23 and the wall part 42, the foaming member 31 is restricted in the direction in which the foamable member 31 foams. Thereby, the foaming which goes to the internal peripheral surface of a structural member (hollow structure 93) can be promoted easily. The foam 94 is formed by performing this heating for a predetermined time. The foam 94 according to the present embodiment is formed so as to connect between the standing portion 23 and the second panel 92.

  Thus, in the component member (hollow structure 93) to which the foam filler 11 is applied, strength, rigidity, vibration damping properties, and the like are improved. For example, the load from the outside of the second panel 92 is distributed to the standing portion 23 via the foam 94.

The effects exhibited by the first embodiment described above will be described below.
(1) The accommodating member 41 included in the foam filler 11 includes a cover portion 43 that protrudes from the wall portion 42 facing the standing portion 23 toward the standing portion 23, and the foamable member 31 includes the wall portion 42. It is provided between the standing portion 23. According to this configuration, heat generated along with the welding of the fixing portion 22 and the first panel 91 is not easily transmitted to the foamable member 31 and the direction in which the foamable member 31 foams is restricted. That is, since the foamable member 31 is not easily affected by unnecessary heat when the fixing portion 22 and the first panel 91 are welded, for example, the foam 94 is stably formed by heating in the drying process. become. In the formation process of the stable foam 94 as described above, the foaming direction is restricted between the standing portion 23 and the wall portion 42, so that foaming to the inner peripheral surface of the component member (hollow structure 93) is performed. Is suitably performed. For this reason, according to the foam filler 11 of this embodiment, it becomes easy to form the foam 94 efficiently in the specified area | region.

  (2) Since the foamable member 31 is separated from the standing portion 23, the coating liquid used for electrodeposition coating can enter between the foamable member 31 and the standing portion 23. Thereby, coating of the standing part 23 comes to be performed suitably. Therefore, corrosion of the standing portion 23 is easily suppressed.

  (3) The standing portion 23 has a contact surface 25 that comes into contact with the foam 94. According to this configuration, for example, when a load or vibration is applied from the second panel 92 to the foam 94, the load or vibration is easily transmitted to the standing portion 23. That is, since the load and vibration are easily dispersed between the foam 94 and the standing portion 23, the reinforcing effect and the vibration damping effect by the foam filler 11 are more easily obtained.

(4) The standing portion 23 has a through hole 24, and the fixing member 51 includes an engaging portion that engages with the through hole 24. In this case, complication in the shape of the standing portion 23 can be avoided as much as possible.
(5) The fixing member 51 is provided integrally with the housing member 41. In this case, the number of parts of the foam filler 11 can be reduced.

The locking tool 83 has a head portion 84, an insertion portion 85 inserted into the locking hole 82 a and the through hole 24, and a locking portion 86 locked to the standing portion 23. That is, the locking tool 83 that is the fixing member 81 of the second embodiment is configured as an engaging portion that engages with the through hole 24. The locking tool 83 is made of a material that can withstand heating when the foamable member 61 becomes a foam.

The standing portion 23 is disposed between the first foamable member 62 and the second foamable member 63. In addition, the first foamable member 62 and the second foamable member 63 are separated from the standing portion 23.
In the standing portion 23, the foam formed from the first foamable member 62 contacts the surface facing the first wall portion 72 a, while the second foamable property is formed on the surface facing the second wall portion 73 a. The foam formed from the member 63 comes into contact. Thus, the standing part 23 of 2nd Embodiment is the contact surface 25 in which the both surfaces contact a foam.

According to the foam filler 12 of 2nd Embodiment mentioned above, the effect similar to the effect as described in (1)-(4) of 1st Embodiment is exhibited. Furthermore, the following effects are exhibited in the second embodiment.
(6) The standing portion 23 is disposed between the first foamable member 62 and the second foamable member 63. And both surfaces of the standing part 23 are comprised as the contact surface 25 which contacts a foam. According to this structure, it becomes easy to ensure the contact surface 25 of the standing part 23 and a foam wider than the foaming filler 11 of 1st Embodiment. For this reason, the reinforcing effect and the vibration damping effect by the foam filler 12 are more easily obtained than the foam filler 11 of the first embodiment.

  (7) The connecting portion 74 has a shape straddling the standing portion 23. When comprised in this way, the accommodating member 71 with which the 1st accommodating part 72 and the 2nd accommodating part 73 were united can be comprised easily. Further, according to the housing member 71 having the connecting portion 74, the assembly to the standing portion 23 is facilitated. For this reason, the productivity of the foam filler 12 can be improved.

  For example, when an external force toward the fixing portion 22 is applied to the housing member 71, the connecting portion 74 straddling the standing portion 23 comes into contact with the standing portion 23 and resists the external force. For this reason, the reinforcing effect by the foam filler 12 can be more easily obtained.
