Abstract
Description
本発明は、2つの部材をボスを介して固定するための部材の固定構造に関する。 The present invention relates to a member fixing structure for fixing two members via a boss.
従来、基部から突出するボスを有する第1部材と、ボスの先端が固定される基部を有する第2部材とを備えた部材の固定構造が知られている(特許文献1参照)。具体的に、この構造では、ボスの周囲に、ボスの補強用もしくは2つの部材の間隔を保持するためのリブが、基部とボスを繋ぐように放射状に形成されている。 2. Description of the Related Art Conventionally, a member fixing structure including a first member having a boss protruding from a base and a second member having a base to which the tip of the boss is fixed is known (see Patent Document 1). Specifically, in this structure, ribs for reinforcing the boss or maintaining the distance between the two members are radially formed around the boss so as to connect the base and the boss.
しかしながら、従来技術では、第1部材のボス付近に、ボスの軸方向に沿った荷重が第1部材側から第2部材側に向けて加わると、リブの根元(リブと基部の間の隅部)に応力が集中するおそれがあったので、応力を確実に分散することが望まれていた。 However, in the related art, when a load along the axial direction of the boss is applied near the boss of the first member from the first member side toward the second member side, the root of the rib (the corner between the rib and the base) ), There is a possibility that the stress is concentrated. Therefore, it has been desired to distribute the stress reliably.
そこで、本発明は、ボスの軸方向に荷重が加わった場合であっても、リブの根元に応力が集中するのを確実に抑えることができる部材の固定構造を提供することを目的とする。 Therefore, an object of the present invention is to provide a member fixing structure capable of reliably suppressing stress concentration at the base of a rib even when a load is applied in the axial direction of the boss.
前記した課題を解決するため、本発明の請求項1に係る発明は、基部から突出するボスと、基部とボスを繋ぐようにボスから放射状に延びる複数のリブとを有する第1部材と、
前記リブの縁部が接触した状態で前記ボスの先端が固定される基部を有する第2部材とを備えた部材の固定構造であって、前記リブの縁部のうち、前記ボスの先端側から前記第1部材の基部に向かって形成される部位であり、前記第1部材の基部と前記第2部材の基部との間に露出する部位には、切欠が形成されていることを特徴とする。
In order to solve the above-described problem, the invention according to
A member fixing structure including a second member having a base to which the tip of the boss is fixed in a state where the edge of the rib is in contact with the edge of the rib, from the tip of the boss It is a site | part formed toward the base of the said 1st member, The notch is formed in the site | part exposed between the base of the said 1st member, and the base of the said 2nd member, It is characterized by the above-mentioned. .
請求項1に係る発明によれば、リブの縁部のうちの第1部材の基部と第2部材の基部との間に露出する部位に切欠が形成されるので、第1部材のボス付近に軸方向に沿った荷重が加わった場合には、切欠に応力を集中させることができる。そのため、リブの根元部分に応力が集中するのを確実に抑えることができる。 According to the first aspect of the present invention, since the notch is formed in the exposed portion between the base portion of the first member and the base portion of the second member in the edge portion of the rib, in the vicinity of the boss of the first member. When a load along the axial direction is applied, stress can be concentrated in the notch. Therefore, it is possible to reliably suppress stress concentration on the root portion of the rib.
請求項2に係る発明は、前記第1部材の基部が、内部に複数の気泡を有する発泡樹脂材料で形成されていることを特徴とする。
The invention according to
請求項2に係る発明によれば、発泡樹脂材料により軽量化を図ることができるとともに、リブの根元付近に発生する応力を切欠によって小さくすることで強度が低い発泡樹脂材料に対する荷重の影響を少なくすることができる。
According to the invention of
請求項3に係る発明は、前記第1部材の基部が、前記発泡樹脂材料を挟み込む一対のスキン層を有し、前記切欠を、前記リブの根元から前記リブが形成されている側のスキン層の厚み以上の高さに設けたことを特徴とする。 According to a third aspect of the present invention, the base portion of the first member has a pair of skin layers sandwiching the foamed resin material, and the cutout is formed on the side where the ribs are formed from the base of the ribs. It is characterized by being provided at a height higher than the thickness.
ここで、リブの根元からリブが形成されている側のスキン層の厚み以上の高さに切欠を設けた場合には、リブの根元に応力が集中しにくいことが実験やシミュレーション等で確認されている。そのため、請求項3に係る発明によれば、リブの根元へ加わる応力を確実に小さくすることができる。 Here, when a notch is provided at a height higher than the thickness of the skin layer on the side where the rib is formed from the rib base, it has been confirmed by experiments, simulations, etc. that stress is unlikely to concentrate at the rib root. ing. Therefore, according to the invention which concerns on Claim 3, the stress added to the base of a rib can be made small reliably.
請求項4に係る発明は、前記切欠を1つのリブに対して複数設けたことを特徴とする。 The invention according to claim 4 is characterized in that a plurality of the notches are provided for one rib.
請求項4に係る発明によれば、応力を複数の切欠に分散させることができるので、応力をより分散させて、リブの根元へ加わる応力をより小さくすることができる。 According to the invention which concerns on Claim 4, since stress can be disperse | distributed to a some notch, stress can be disperse | distributed more and the stress added to the root of a rib can be made smaller.
請求項1に係る発明によれば、ボスの軸方向に荷重が加わった場合であっても、リブの根元部分に応力が集中するのを確実に抑えることができる。 According to the first aspect of the present invention, even when a load is applied in the axial direction of the boss, it is possible to reliably suppress stress concentration at the root portion of the rib.
請求項2に係る発明によれば、軽量化を図ることができるとともに、発泡樹脂材料への荷重の影響を、切欠によって少なくすることができる。
According to the invention which concerns on
請求項3に係る発明によれば、応力が集中する切欠をリブの根元から遠く離すため、リブの根元へ加わる応力を確実に小さくすることができる。 According to the invention which concerns on Claim 3, since the notch where stress concentrates is separated away from the base of a rib, the stress added to the base of a rib can be made small reliably.
請求項4に係る発明によれば、応力をより分散させて、リブの根元へ加わる応力をより小さくすることができる。 According to the invention which concerns on Claim 4, a stress can be disperse | distributed more and the stress added to the base of a rib can be made smaller.
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
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
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
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
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
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
<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
The
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
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
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
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
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
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
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
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
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。
