本実施形態の区画用部材１１は、発泡性部材２１を支持するとともに中空構造部材６１に取り付けられる支持部材３１をさらに備えている。支持部材３１は、発泡性部材２１を支持する支持本体部３２と、中空構造部材６１の有する貫通孔６１ｂに取り付けられる係止部３３とを備えている。支持本体部３２には、発泡性部材２１が嵌合、接着、粘着等により取り付けられる。このように区画用部材１１は、支持部材３１と発泡性部材２１とが一体となった構造を有している。支持部材３１の係止部３３は、中空構造部材６１の貫通孔６１ｂに挿入されるとともに中空構造部材６１の外面に係止される。 The partition member 11 of the present embodiment further includes a support member 31 that supports the foamable member 21 and is attached to the hollow structure member 61. The support member 31 includes a support main body portion 32 that supports the foamable member 21 and a locking portion 33 that is attached to the through hole 61 b of the hollow structural member 61. The foamable member 21 is attached to the support main body 32 by fitting, adhesion, adhesion, or the like. Thus, the partition member 11 has a structure in which the support member 31 and the foamable member 21 are integrated. The locking portion 33 of the support member 31 is inserted into the through hole 61 b of the hollow structure member 61 and locked to the outer surface of the hollow structure member 61.
支持部材３１は、発泡性部材２１の加熱及び発泡させる際の熱に耐え得る材料から構成される。支持部材３１の材質としては、例えば、樹脂系材料、及び金属系材料が挙げられる。支持部材３１は、車両の軽量化の観点から、ポリアミド等の樹脂系材料から構成されることが好ましい。 The support member 31 is made of a material that can withstand heat when the foamable member 21 is heated and foamed. Examples of the material of the support member 31 include a resin material and a metal material. The support member 31 is preferably made of a resin-based material such as polyamide from the viewpoint of weight reduction of the vehicle.
第１区画用部材１２及び第２区画用部材１３は、中空構造部材６１の長さ方向において離間して配置される。第２区画用部材１３を構成する支持部材３１（支持本体部３２）は、中空構造部材６１の縦断面において、第１区画用部材１２を構成する平板状の支持部材３１（支持本体部３２）との間隔を調整する傾斜部３２ａを有している。第２区画用部材１３の支持本体部３２と、第１区画用部材１２の支持本体部３２との間隔は、第１の間隔Ｄ１と、この第１の間隔Ｄ１よりも広い第２の間隔Ｄ２とを有している。 The first partition member 12 and the second partition member 13 are spaced apart from each other in the length direction of the hollow structural member 61.

The distance between the support main body 32 of the second partition member 13 and the support main body 32 of the first partition member 12 is a first distance D1 and a second distance D2 wider than the first distance D1. And have.
なお、中空構造部材６１は、第１パネル６２と第２パネル６３とを、例えばスポット溶接等により接合することで形成される。中空構造部材６１としては、例えば、長さ方向を有するピラー、メンバ、リインフォース等が挙げられる。区画用部材配置工程では、第１パネル６２及び第２パネル６３の少なくとも一方（本実施形態では第１パネル６２）に、区画用部材１１を取り付けた後、第１パネル６２と第２パネル６３とを接合することで、中空構造部材６１を形成するとともに区画用部材１１を中空部６１ａに配置することができる。 The hollow structural member 61 is formed by joining the first panel 62 and the second panel 63 by, for example, spot welding. Examples of the hollow structural member 61 include a pillar having a length direction, a member, and reinforcement. In the partition member arranging step, after the partition member 11 is attached to at least one of the first panel 62 and the second panel 63 (the first panel 62 in the present embodiment), the first panel 62 and the second panel 63 By joining, the hollow structural member 61 can be formed and the partition member 11 can be disposed in the hollow portion 61a.
ここで、第１パネル６２と第２パネル６３とを組み付ける際に、区画用部材１１が第１パネル６２又は第２パネル６３に当接すると、第１パネル６２又は第２パネル６３に部分的に不要な外力が加わり、第１パネル６２又は第２パネル６３を変形させるおそれがある。こうした変形を回避するために、区画用部材１１は、中空構造部材６１の内面との間に間隙が形成される寸法に設定される。 Here, when the partitioning member 11 comes into contact with the first panel 62 or the second panel 63 when the first panel 62 and the second panel 63 are assembled, the first panel 62 or the second panel 63 is partially Unnecessary external force may be applied to deform the first panel 62 or the second panel 63. In order to avoid such a deformation, the partitioning member 11 is set to a dimension in which a gap is formed between the inner surface of the hollow structural member 61.
図１（ｂ）に示すように、区画壁形成工程では、上述した発泡性部材２１を加熱することで発泡及び硬化させて中空部６１ａ内を区画する区画壁４１を形成する。本実施形態では、第１区画用部材１２から第１区画壁４２を形成するとともに、第２区画用部材１３から第２区画壁４３を形成する。第１区画壁４２及び第２区画壁４３は、それぞれ支持部材３１と、発泡性部材２１から形成された発泡体（以下、区画用発泡体２２という。）を備えている。 As shown in FIG. 1B, in the partition wall forming step, the foamable member 21 described above is heated to be foamed and cured to form the partition wall 41 that partitions the hollow portion 61a. In the present embodiment, the first partition wall 42 is formed from the first partition member 12, and the second partition wall 43 is formed from the second partition member 13. Each of the first partition wall 42 and the second partition wall 43 includes a support member 31 and a foam formed from the foamable member 21 (hereinafter referred to as a partition foam 22).
詳述すると、発泡性部材２１は、中空部６１ａ内に露出しており、区画壁形成工程における外部からの加熱により、区画用部材１１（支持部材３１）と中空構造部材６１の内面との間隙に入り込んだ部分を有する区画用発泡体２２を形成する。区画用発泡体２２は、支持部材３１と中空構造部材６１とを連結している。 More specifically, the foamable member 21 is exposed in the hollow portion 61 a, and the gap between the partition member 11 (support member 31) and the inner surface of the hollow structure member 61 due to external heating in the partition wall forming step. A partition foam 22 having an intruded portion is formed. The partition foam 22 connects the support member 31 and the hollow structural member 61.
区画壁形成工程は、区画用部材配置工程の後に行われる車両の塗装工程において塗料を加熱乾燥させる際の加熱により行われることが好ましい。詳述すると、中空構造部材６１を備えた車両の塗装工程では、例えば、防錆を目的とした電着液等の塗料を付着させた後、塗料の加熱乾燥（焼き付け）が行われる。すなわち、車両の塗装工程において、塗料を加熱乾燥させる際に、車両の中空構造部材６１が加熱されるため、この加熱を利用して発泡性部材２１を発泡及び硬化させることができる。 The partition wall forming step is preferably performed by heating when the paint is heated and dried in the vehicle coating step performed after the partition member arranging step. More specifically, in the painting process of the vehicle provided with the hollow structural member 61, for example, after a paint such as an electrodeposition liquid for the purpose of rust prevention is adhered, the paint is heated and dried (baked). That is, when the paint is heated and dried in the vehicle painting process, the hollow structural member 61 of the vehicle is heated, so that the foamable member 21 can be foamed and cured using this heating.
なお、区画壁形成工程前の区画用部材１１と中空構造部材６１の内面との間の間隙は、車両の塗装工程において車両を電着液で塗装する際に電着液の流通路となる。
図２（ａ）及び図２（ｂ）に示すように、発泡体充填工程では、中空部６１ａに液状の発泡性材料５１を流入し、発泡性材料５１が発泡する範囲を区画壁４１により制限しながら充填用発泡体５２を充填する。
Note that the gap between the partition member 11 and the inner surface of the hollow structural member 61 before the partition wall forming process becomes a flow path for the electrodeposition liquid when the vehicle is coated with the electrodeposition liquid in the vehicle coating process.
As shown in FIGS. 2A and 2B, in the foam filling process, the liquid foamable material 51 flows into the hollow portion 61 a and the range in which the foamable material 51 foams is limited by the partition wall 41. While filling, the filling foam 52 is filled.
液状の発泡性材料５１としては、周知の常温硬化性材料（発泡体原料）を用いることができる。発泡性材料５１としては、例えば、ポリオール成分を含有する第１液と、イソシアネート成分を含有する第２液とから構成される２液硬化型ウレタン系材料が挙げられる。 As the liquid foamable material 51, a known room temperature curable material (foam raw material) can be used. Examples of the foamable material 51 include a two-component curable urethane material composed of a first liquid containing a polyol component and a second liquid containing an isocyanate component.
発泡体充填工程では、中空構造部材６１の有する注入孔６１ｃに挿入されたノズルＮから、第１区画壁４２と第２区画壁４３との間に位置する中空部６１ａに液状の発泡性材料５１を流入する。これにより、液状の発泡性材料５１が発泡する範囲を第１区画壁４２及び第２区画壁４３により制限しながら充填用発泡体５２を充填することができる。本実施形態の中空部６１ａでは、一対の支持部材３１と区画用発泡体２２と充填用発泡体５２とが連結された構造が形成されている。 In the foam filling step, the liquid foamable material 51 is supplied from the nozzle N inserted into the injection hole 61 c of the hollow structural member 61 to the hollow portion 61 a located between the first partition wall 42 and the second partition wall 43. Inflow. Accordingly, the filling foam 52 can be filled while the range in which the liquid foamable material 51 is foamed is limited by the first partition wall 42 and the second partition wall 43. In the hollow portion 61a of the present embodiment, a structure in which the pair of support members 31, the partition foam 22, and the filling foam 52 are connected is formed.
本実施形態の第２区画壁４３は、傾斜部３２ａを有しているため、充填用発泡体５２が充填された中空構造部材６１は、充填用発泡体５２の充填量が異なる複数の横断面を有している。例えば、図２（ｂ）に示すＡ−Ａ線に沿った横断面における充填用発泡体５２の充填量に対してＢ−Ｂ線に沿った横断面における発泡体の充填量は多い。 Since the second partition wall 43 of the present embodiment has the inclined portion 32a, the hollow structural member 61 filled with the filling foam 52 has a plurality of cross sections with different filling amounts of the filling foam 52. have. For example, the filling amount of the foam in the cross section along the line BB is larger than the filling amount of the filling foam 52 in the cross section along the line AA shown in FIG.
上述した実施形態によって発揮される作用効果について以下に記載する。
（１）発泡体の充填方法は、加熱により発泡及び硬化する発泡性部材２１を備えた区画用部材１１を中空部６１ａに配置する区画用部材配置工程と、発泡性部材２１を加熱することで発泡及び硬化させて中空部６１ａ内を区画する区画壁４１を形成する区画壁形成工程とを備えている。発泡体の充填方法は、中空部６１ａに発泡性材料５１を流入し、発泡性材料５１が発泡する範囲を区画壁４１により制限しながら充填用発泡体５２を充填する発泡体充填工程を備えている。

Accordingly, it is possible to inject the liquid foamable material 51 while reducing the complexity when the hollow portion 61a of the hollow structural member 61 is partitioned.
また、区画壁形成工程において、発泡性部材２１の発泡及び硬化により形成された区画壁４１は、例えば、従来の粒状体のように流動性を有しないため、発泡体充填工程において区画壁４１の位置ずれが発生し難い。これにより、発泡性材料５１が発泡する範囲を好適に制限することができる。 Further, in the partition wall forming step, the partition wall 41 formed by foaming and curing of the foamable member 21 does not have fluidity like, for example, a conventional granular material. Misalignment is unlikely to occur. Thereby, the range which the foamable material 51 foams can be restrict | limited suitably.

（５）発泡体の充填方法は、区画用部材配置工程の後に行われる車両の塗装工程において塗料を加熱乾燥させる際の加熱により行われることが好ましい。この場合、既存の塗装設備を利用して区画壁形成工程を行うことができるため、塗装と発泡体の充填を含む車両の製造設備を簡略化することができる。 (5) The foam filling method is preferably performed by heating when the paint is heated and dried in the vehicle coating process performed after the partition member arranging process. In this case, since the partition wall forming step can be performed using the existing painting equipment, the vehicle production equipment including painting and foam filling can be simplified.
（６）発泡体の充填方法において第２区画用部材１３の支持部材３１は、傾斜部３２ａを有している。この場合、中空構造部材６１において充填用発泡体５２の充填量が異なる複数の横断面を有するように構成することができる。すなわち、傾斜部３２ａにより中空構造部材６１の長さ方向における充填用発泡体５２の充填量を変更することができるため、中空構造部材６１を備えた車両の補強性能や制振性能を容易に調整することができる。 (6) In the foam filling method, the support member 31 of the second partition member 13 has an inclined portion 32a. In this case, the hollow structural member 61 can be configured to have a plurality of cross sections in which the filling amount of the filling foam 52 is different. That is, since the filling amount of the filling foam 52 in the length direction of the hollow structural member 61 can be changed by the inclined portion 32a, the reinforcing performance and the vibration damping performance of the vehicle including the hollow structural member 61 are easily adjusted. can do.
（変更例）
上記実施形態を次のように変更して構成してもよい。
・前記第２区画用部材１３を省略してもよい。すなわち、区画用部材１１（区画壁４１）の数は、単数であってもよい。また、区画用部材１１（区画壁４１）は、第３区画用部材（第３区画壁）等を含む３つ以上から構成してもよい。
(Example of change)
The above embodiment may be modified as follows.
The second partition member 13 may be omitted. That is, the number of partition members 11 (partition walls 41) may be singular. Further, the partition member 11 (partition wall 41) may be composed of three or more members including a third partition member (third partition wall) and the like.
・前記区画用部材１１の支持部材３１における係止部３３を省略してもよい。すなわち、支持本体部３２に必要に応じて取付部を設けた支持部材を溶接や接着等により中空構造部材６１に取り付けてもよい。 The locking portion 33 in the support member 31 of the partition member 11 may be omitted. That is, you may attach the support member which provided the attaching part to the support main body part 32 as needed to the hollow structure member 61 by welding, adhesion | attachment, etc.
・前記第１区画用部材１２の支持部材３１と第２区画用部材１３の支持部材３１の形状は、適宜変更してもよく、例えば、互いに同じ形状であってもよい。例えば、第１区画用部材１２の支持部材３１が傾斜部を有していてもよいし、第２区画用部材１３の支持部材３１における傾斜部３２ａを省略してもよい。 The shapes of the support member 31 of the first partition member 12 and the support member 31 of the second partition member 13 may be appropriately changed. For example, the shapes may be the same. For example, the support member 31 of the first partition member 12 may have an inclined portion, or the inclined portion 32a of the support member 31 of the second partition member 13 may be omitted.
・前記区画用部材１１の支持部材３１（支持本体部３２）は、車両の塗装工程において塗料を流通させる流通孔を有していてもよい。なお、区画壁形成工程において前記流通孔を閉塞してもよい。 The support member 31 (support main body portion 32) of the partition member 11 may have a flow hole through which paint is circulated in the vehicle painting process. Note that the flow hole may be closed in the partition wall forming step.
・前記区画壁形成工程において、発泡性部材２１から形成された区画用発泡体２２は、支持部材３１と中空構造部材６１との間隙を内周面の全周にわたって閉塞していてもよいし、前記間隙を部分的に閉塞していてもよい。区画壁４１は、前記間隙を狭めたり、部分的に閉塞したりすることで、前記間隙から漏れ出して形成される充填用発泡体５２を削減することができる。なお、例えば、第２区画壁４３と中空構造部材６１との間の間隙（第２区画壁４３を挟んで連通する連通部分）を部分的に残しておくことで、液状の発泡性材料５１の過剰な発泡圧を放圧させることができる。これにより、例えば、発泡圧を要因とした中空構造部材６１（第１パネル６２又は第２パネル６３）の変形を抑制することが可能となる。 In the partition wall forming step, the partition foam 22 formed from the foamable member 21 may close the gap between the support member 31 and the hollow structure member 61 over the entire inner peripheral surface, The gap may be partially closed. The partition wall 41 can reduce the filling foam 52 formed by leaking from the gap by narrowing or partially closing the gap. In addition, for example, by leaving a gap between the second partition wall 43 and the hollow structural member 61 (a communication portion communicating with the second partition wall 43 in between), the liquid foamable material 51 Excessive foaming pressure can be released. Thereby, for example, it is possible to suppress the deformation of the hollow structural member 61 (the first panel 62 or the second panel 63) due to the foaming pressure.
・前記区画用部材１１の支持部材３１を省略し、発泡性部材のみから区画用部材１１を構成してもよい。この場合、例えば、自己粘着性を有するシート状の発泡性部材に変更し、この発泡性部材を中空構造部材６１（第１パネル６２又は第２パネル６３）に貼り付けることで中空部６１ａに配置することができる。また、例えば、発泡性を有するペーストを中空構造部材６１（第１パネル６２又は第２パネル６３）に塗布することで中空部６１ａにペーストの塗布層からなる発泡性部材を配置することもできる。 The support member 31 of the partition member 11 may be omitted, and the partition member 11 may be configured only from the foamable member. In this case, for example, it is changed to a sheet-like foaming member having self-adhesiveness, and this foaming member is attached to the hollow structural member 61 (the first panel 62 or the second panel 63) and arranged in the hollow portion 61a. can do. Further, for example, by applying a foaming paste to the hollow structural member 61 (the first panel 62 or the second panel 63), a foaming member made of a paste coating layer can be disposed in the hollow portion 61a.
・前記発泡体充填工程において、第２区画壁４３を挟んだ両側の中空部６１ａに充填用発泡体を充填してもよい。例えば、第１区画壁４２と第２区画壁４３との間の中空部６１ａに充填する充填用発泡体５２と、第２区画壁４３で区画されるとともに第１区画壁４２と反対側となる中空部６１ａに充填する充填用発泡体とを異なる組成にすることで、車両の補強性能や制振性能を調整することもできる。 In the foam filling step, the filling foam may be filled in the hollow portions 61a on both sides of the second partition wall 43. For example, the filling foam 52 that fills the hollow portion 61 a between the first partition wall 42 and the second partition wall 43 and the second partition wall 43 and the opposite side of the first partition wall 42 are provided. The reinforcing performance and damping performance of the vehicle can be adjusted by making the filling foam filled in the hollow portion 61a have a different composition.
・前記中空構造部材６１の長さ方向は、鉛直方向、水平方向、又は、鉛直方向及び水平方向の両方向に対して傾斜する傾斜方向のいずれの方向であってもよい。 The length direction of the hollow structural member 61 may be any of a vertical direction, a horizontal direction, or an inclination direction that is inclined with respect to both the vertical direction and the horizontal direction.
