以下、図面を参照しながら、本発明の一実施形態について説明する。
図1に示すように、部材の固定構造Mは、板状の第1部材1と、板状の第2部材2とを備えている。なお、第1部材1や第2部材2としては、どのような部材を採用してもよく、例えばドアライニングや当該ドアライングに取り付けるアームレストなどの部材を採用することができる。
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the member fixing structure M includes a plate-like first member 1 and a plate-like second member 2. In addition, as the 1st member 1 and the 2nd member 2, what kind of members may be employ | adopted, for example, members, such as a door lining and an armrest attached to the said door line, are employable.

第1部材1は、板状の基部11と、基部11から第2部材2に向けて突出するボス12と、基部11とボス12を繋ぐようにボス12から放射状(十字状)に延びる4つ(複数)のリブ13とを有している。   The first member 1 includes a plate-like base 11, four bosses 12 projecting from the base 11 toward the second member 2, and four radially extending from the boss 12 so as to connect the base 11 and the boss 12. And a plurality of ribs 13.

基部11は、内部に複数の気泡を有する発泡樹脂材料11aと、当該発泡樹脂材料11aを挟み込む一対のスキン層11bとで形成されている。なお、発泡樹脂材料11aとしては、どのような材料を採用してもよく、例えば発泡ポリプロピレンなどを採用することができる。   The base 11 is formed of a foamed resin material 11a having a plurality of bubbles therein and a pair of skin layers 11b that sandwich the foamed resin material 11a. In addition, as the foamed resin material 11a, any material may be employed, for example, foamed polypropylene or the like may be employed.

ボス12とリブ13は、一方(第2部材2側)のスキン層11bに一体に形成されている。なお、リブ13については、後で詳述する。   The boss 12 and the rib 13 are integrally formed on one (second member 2 side) skin layer 11b. The rib 13 will be described in detail later.

第2部材2は、樹脂で形成された板状の部材であり、板状の基部21を有している。   The second member 2 is a plate-like member made of resin and has a plate-like base portion 21.

基部21には、ボス12の先端12aを固定するための孔21aが形成されている。具体的に、ボス12の先端12aは、図2に示すように、基部21の孔21aを貫通した後、加熱された治具で溶融されることで基部21に固着される。より具体的には、基部21には、リブ13の縁部130(支持部131)が接触した状態でボス12の先端12aが固定されるようになっている。   A hole 21 a for fixing the tip 12 a of the boss 12 is formed in the base portion 21. Specifically, as shown in FIG. 2, the tip 12 a of the boss 12 passes through the hole 21 a of the base portion 21 and is then fixed to the base portion 21 by being melted by a heated jig. More specifically, the tip end 12a of the boss 12 is fixed to the base portion 21 in a state where the edge portion 130 (support portion 131) of the rib 13 is in contact.

<リブの詳細構造>
以下に、リブ13の詳細構造について説明する。
リブ13は、板状に形成されており、その縁部130が、第2部材2の基部21に接触する支持部131と、ボス12の先端12a側から基部11に向かって形成される側部132とを主に有した構成となっている。そして、側部132は、図2に示すように、第1部材1と第2部材2とが固定された状態において、第1部材1の基部11と第2部材2の基部21との間に露出しており、その第2部材2側には、段差状(直角)の切欠133が形成されている。
<Detailed structure of rib>
Below, the detailed structure of the rib 13 is demonstrated.
The rib 13 is formed in a plate shape, and the edge portion 130 of the rib 13 is in contact with the base portion 21 of the second member 2 and the side portion formed from the tip 12a side of the boss 12 toward the base portion 11. 132. As shown in FIG. 2, the side portion 132 is between the base portion 11 of the first member 1 and the base portion 21 of the second member 2 in a state where the first member 1 and the second member 2 are fixed. A stepped (right angle) notch 133 is formed on the second member 2 side.

これにより、図2に矢印で示すように、第1部材1側から第2部材2側に向けて第1部材1のボス12付近に軸方向に衝突荷重が加わって、第1部材1の基部11がボス12を中心に下側(第2部材2側)に凹むように撓んだ場合には、切欠133に応力が集中するようになっている。さらに、切欠133が形成されたリブ13は、弾性変形しやすくなっているため、衝突荷重をリブ13の弾性変形によっても吸収することができる。   Thereby, as indicated by an arrow in FIG. 2, a collision load is applied in the axial direction near the boss 12 of the first member 1 from the first member 1 side toward the second member 2 side. When 11 is bent so as to be recessed downward (second member 2 side) around the boss 12, stress is concentrated in the notch 133. Furthermore, since the rib 13 in which the notch 133 is formed is easily elastically deformed, the collision load can be absorbed also by elastic deformation of the rib 13.

また、切欠133は、4つのすべてのリブ13に形成されている。これにより、各リブ13の根元13aへの応力集中を確実に抑えることが可能となっている。   The notches 133 are formed in all four ribs 13. Thereby, it is possible to reliably suppress stress concentration on the root 13a of each rib 13.

なお、この切欠133は、第2部材2を支持するための切欠ではなく、リブ13の根元13aに応力が集中しないようにするための切欠であるため、第2部材2に接触しない限り、リブ13の根元13a(基部11の裏面111)から遠く離れた位置に設けるのが好ましい。   The notch 133 is not a notch for supporting the second member 2 but a notch for preventing stress from concentrating on the root 13a of the rib 13. It is preferable to provide it at a position far from 13 roots 13a (back surface 111 of the base 11).

具体的には、切欠133は、リブ13の根元13aからリブ13が形成されている側のスキン層11bの厚み以上の高さとなる位置に設けるのが好ましい。その理由の1つは、実験やシミュレーション等によって、リブ13が形成されている側のスキン層11bの厚み以上の高さ位置に切欠133を設けると、リブ13の根元13aへの応力集中が分散されて基部11への荷重の影響が小さくなることが確認されているからである。また、第2の理由は、リブ13が形成されている側のスキン層11bの厚み未満の高さ位置に切欠を設けると、リブの根元への応力集中は分散されるが切欠に応力が集中しすぎて基部に対して荷重の影響が出るおそれがあることが確認されているからである。   Specifically, the notch 133 is preferably provided at a position that is higher than the thickness of the skin layer 11 b on the side where the rib 13 is formed from the base 13 a of the rib 13. One of the reasons is that if a notch 133 is provided at a height position higher than the thickness of the skin layer 11b on the side where the ribs 13 are formed by experiments or simulations, the stress concentration on the roots 13a of the ribs 13 is dispersed. This is because it is confirmed that the influence of the load on the base 11 is reduced. The second reason is that if a notch is provided at a height position less than the thickness of the skin layer 11b on the side where the rib 13 is formed, the stress concentration at the root of the rib is dispersed, but the stress is concentrated at the notch. This is because it has been confirmed that there is a possibility that the load may be affected by the excessive load.

以上、本実施形態によれば、切欠133に応力を集中させることができるので、リブ13の根元13aに応力が集中するのを確実に抑えることができる。また、本実施形態では、このようにリブ13の根元13aへの応力集中を抑えることができるので、薄いスキン層11bを有する発泡樹脂材料11aを用いることができ、軽量化を図ることが可能となっている。   As described above, according to the present embodiment, stress can be concentrated on the notch 133, so that it is possible to reliably suppress stress concentration on the root 13 a of the rib 13. Moreover, in this embodiment, since the stress concentration on the root 13a of the rib 13 can be suppressed in this way, the foamed resin material 11a having the thin skin layer 11b can be used, and the weight can be reduced. It has become.

以上に本発明の実施形態について説明したが、本発明は、以下の他の形態に示すように、適宜変形して実施することが可能である。なお、以下の説明では、前記実施形態と略同様の構成要素については、同一符号を付し、その説明を省略することとする。   Although the embodiments of the present invention have been described above, the present invention can be implemented with appropriate modifications as shown in other embodiments below. In the following description, components that are substantially the same as those in the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

前記実施形態では、1つのリブ13に1つの切欠133を設けたが、本発明はこれに限定されず、例えば図3に示すように、1つのリブ13に2つ(複数)の切欠133を設けてもよい。これによれば、2つの切欠133に応力を分散させることができるので、リブ13の根元13aに加わる応力をより小さくすることができる。なお、切欠は、3つ以上設けてもよい。   In the embodiment, one notch 133 is provided in one rib 13, but the present invention is not limited to this. For example, as shown in FIG. 3, two (plural) notches 133 are provided in one rib 13. It may be provided. According to this, since the stress can be dispersed in the two notches 133, the stress applied to the root 13a of the rib 13 can be further reduced. Three or more notches may be provided.

前記実施形態では、すべてのリブ13に切欠133を設けたが、本発明はこれに限定されず、少なくとも1つのリブに切欠を設ければよい。また、切欠の形状は、リブの途中で応力分散することが可能であれば、どのような形状であってもよい。   In the above-described embodiment, the notches 133 are provided in all the ribs 13. However, the present invention is not limited to this, and the notches may be provided in at least one rib. Further, the shape of the notch may be any shape as long as stress can be dispersed in the middle of the rib.

前記実施形態では、ボス12の先端12aを溶着することで第2部材2の基部21に固定させたが、本発明はこれに限定されず、例えばボスを第2部材の基部にネジによって締結することで固定してもよい。   In the said embodiment, although it fixed to the base 21 of the 2nd member 2 by welding the front-end | tip 12a of the boss | hub 12, this invention is not limited to this, For example, a boss | hub is fastened to the base of a 2nd member with a screw | thread. You may fix it.

なお、前記実施形態では、基部11を発泡樹脂材料11aで形成したが、本発明はこれに限定されず、非発泡のポリプロピレンのような樹脂材料で形成してもよい。ただし、前記実施形態のように発泡樹脂材料11aを使用した場合には、軽量化を図ることができるが、荷重が加わったときの強度が発泡しない樹脂材料よりも劣る分、本発明の効果による強度向上が特に有効となっている。   In the embodiment, the base 11 is formed of the foamed resin material 11a. However, the present invention is not limited to this, and the base 11 may be formed of a resin material such as non-foamed polypropylene. However, when the foamed resin material 11a is used as in the above-described embodiment, the weight can be reduced. However, the strength of the resin material when the load is applied is inferior to the resin material that does not foam. Strength improvement is particularly effective.
