【発明の属する技術分野】
本発明は、発泡硬化フォーム充填車体部材、更に詳しくは、閉断面構造を有する車体部材の閉断面内部に二液型発泡性材料を注入し、発泡硬化によって発泡硬化フォームを充填するに際し、上記閉断面内部の容積に見合った充填容量の適正を確認するための開口部を設置した発泡硬化フォーム充填車体部材および発泡硬化フォームの充填方法に関する。
【０００２】
【従来の技術と発明が解決しようとする課題】
我国の自動車業界では、車の衝突安全性向上が重要な課題となり、車体全体の剛性や強度の向上が必要となっている。このように、我国での自動車の衝突安全性の要求はますます厳しくなり、より安全度の高い車の生産が要求されつつある。
【０００３】
ところで、かかる衝突安全向上の対策として、各自動車メーカーでは鋼板での補強構造が検討され、独自の車体構造が開発されているが、車１台当りの重量増(一般に３０〜５０kg)は避けられない。
また、かかる構造補強とは別に、衝突など多くの負荷が加わる車体部材、たとえばシートベルト装置のベルトアンカーが装着され、閉断面構造を有するセンターピラーや、その他前部車体の閉断面構造を有するフロントピラー等に対し、それらの閉断面部分(通常、区画の仕切板を設置して閉断面を形成)に二液型発泡性材料を注入し、発泡硬化によって、補強材として機能する発泡硬化フォームを充填する検討が行われている。
【０００４】
この発泡硬化フォームの充填技術は、二液型発泡性材料の発泡倍率やその他発泡条件を考慮した上で、充填すべき閉断面内部の容積に見合う量で定量注入することにより、所望範囲で発泡硬化フォームを充填した、上記センターピラーやフロントピラー等の閉断面構造を有する車体部材を得ることができるようになっている。
しかしながら、不測の事態として注入装置等に故障が起こった場合、発泡硬化フォームの充填容量が所望範囲より不足すると空洞部が生じ、設計強度が得られなくなることが予測される。また、閉断面部分に設けた仕切板の不意の欠損によっても、充填容量の不足を来すことが考えられる。
実際には、このような充填容量の不足を未然に防止するすべはなく、生産ライン後に衝突試験や実車の剛性測定あるいは振動解析を行うことにより、初めて充填容量の適否を判断できるのが現状で、生産ライン途中で、車の設計強度や剛性を保証することはできなかった。
【０００５】
【課題を解決するための手段】
本発明者らは、かかる充填容量の不足による問題点を未然に防止せしめ、発泡硬化フォームを適正に充填して補強した閉断面構造を有する車体部材および充填硬化フォームの充填方法を提供するため鋭意検討を進めたところ、閉断面構造を有する車体部材の特定箇所に、閉断面内部の容積に見合った充填容量の適正を確認するための特定寸法の充填確認開口部を設置したことにより、所期目的が達成しうることを見出し、本発明を完成させるに至った。
【０００６】
すなわち、本発明は、閉断面構造を有する車体部材の閉断面内部に二液型発泡性材料を注入し、発泡硬化によって発泡硬化フォームを充填した車体部材において、上記閉断面内部の容積に見合った充填容量の適正を確認するため、発泡硬化フォームが最終的に到達する限界位置から５０mm以内の手前に、口径１０mm以下の充填確認開口部を設置したことを特徴とする発泡硬化フォーム充填車体部材;および
閉断面構造を有する車体部材の閉断面内部に二液型発泡性材料を注入し、発泡硬化によって発泡硬化フォームを充填する方法において、上記車体部材の発泡硬化フォームが最終的に到達する限界位置から５０mm以内の手前に、口径１０mm以下の充填確認開口部を設置することにより、上記閉断面内部の容積に見合った充填容量の適正を確認することを特徴とする発泡硬化フォームの充填方法を提供するものである。
【０００７】
本発明において閉断面構造を有する車体部材としては、たとえば図１に示される、フロントルーフ１(ルーフレールインナーとルーフレールアウターで構成)とフロントサイドルーフレール２(フロントサイドアウターパネルとサイドルーフレールインナーで構成)とフロントピラー３(フロントサイドアウターパネルとフロントピラーインナーで構成)とを連結した構造部材が挙げられ、フロントサイドルーフレール２およびフロントピラー３のそれぞれの内部に、仕切板４および５が設置され、かつフロントサイドルーフレール２には注入穴６が開設されている。
また他の例として図２の構造部材が挙げられ、該構造部材は、センターピラー７(センターピラーインナーとセンターピラーアウターで構成)とサイドルーフレール８(サイドルーフレールインナーとサイドルーフレールアウターで構成)とを連結したもので、それぞれに仕切板９,１０,１１が設置され、かつ注入穴１２が開設されている。
【０００８】
本発明において上記注入穴６,１２に注入される二液型発泡性材料としては、常温下で発泡硬化しうるものであれば特にその種類に制限はなく、たとえばポリオール主剤[多価アルコール,ビスフェノール類,各種アミンなどの活性水素含有化合物に、アルキレンオキシドを付加反応させて得られるポリエーテルポリオールが好ましい]と、ポリイソシアネート硬化剤[芳香族ポリイソシアネート、脂肪族または脂環式ポリイソシアネート、芳香脂肪族ポリイソシアネート、これらの各種変性物、ポリオール類と過剰のポリイソシアネート化合物との反応で得られる末端ＮＣＯ基含有ウレタンプレポリマーなど]からなり、該主剤側に発泡剤[水、熱分解型化学発泡剤(アゾジカルボジアミド、p,p'−オキシビスベンゼンスルホニルヒドラジドなど)、熱分解型無機発泡剤(炭酸水素ナトリウムなど)、熱膨張型マイクロバルーン(ポリマーカプセルにペンタン、ヘプタンなどの低沸点溶剤を包み込んだもの)等]を配合し、さらに必要に応じて反応触媒、鎖延長剤、整泡剤、着色剤、可塑剤、充填剤、難燃剤、老化防止剤、抗酸化剤などを加えた二液型発泡性ウレタン材料の使用が好適である。
【０００９】
【発明の実施の形態】
本発明に係る発泡硬化フォーム充填車体部材および発泡硬化フォームの充填方法は、上記図１,２に示されるような構造部材の所定箇所に１つまたは２つ以上の充填確認開口部を設置したことを特徴とする。たとえば図１において、注入穴６から二液型発泡材料を注入すると、該発泡材料は最初にフロントピラー３の方へ発泡硬化しながら進み、次いでフロントサイドルーフレール２へと広がり、その間上端部やコーナー部を回って、最終的にフロントルーフ１の上方へと進み、図示の限界位置Ｐに到達する。
従って、かかる限界位置Ｐから５０mm以内、好ましくは１〜３０mm以内の手前に当該充填確認開口部Ｈを設置すれば、形成される発泡硬化フォームの充填容量が不足しているか否かを目視にて確認することができる。この場合、該開口部Ｈから見て、一般に黄色乃至黄褐色であると、発泡硬化フォームの通過を意味し、そうでない場合は空洞状態の暗黒色を示す。
なお、充填確認開口部Ｈの位置が限界位置Ｐの手前５０mmを越えると、発泡硬化フォームの通過を確認しても、その後に適正な充填容量が得られたかどうかの正確な判断が難かしい。
また充填確認開口部Ｈの口径は、１０mm以下、好ましくは１〜７．５mmに設定する。口径が１０mmを越えると、発泡硬化フォームの漏出が見られ、また車体剛性の低下の点で望ましくない。
かかる充填確認開口部Ｈと同様な観点から、図２の構造部材においても、２つの充填確認開口部Ｈ1,Ｈ2を設置する。
【００１０】
このように充填確認開口部の設置により、目視にて発泡硬化フォームの充填容量の適否を確認すると同時に、設計上の強度や剛性の保証が可能となる。また、充填不足の予測される車のむやみの生産を未然に回避できる。しかしながら、上記目視確認において、充填不足が発覚した場合、該充填確認開口部から、たとえば針金などを通し、大体の不足量を計算した上で、別途注入穴を設けて二液型発泡材料の補充注入を行えばよい。
【００１１】

次に実施例を挙げて、本発明をより具体的に説明する。

BACKGROUND OF THE INVENTION
The present invention relates to a foam-cured foam-filled vehicle body member, and more specifically, when a two-component foamable material is injected into a closed cross-section of a vehicle body member having a closed-section structure, and the foam-cured foam is filled by foam curing. The present invention relates to a foam-cured foam-filled vehicle body member provided with an opening for confirming appropriate filling capacity corresponding to the volume inside a cross section, and a foam-cured foam filling method.
[0002]
[Prior art and problems to be solved by the invention]
In Japan's automobile industry, improving the collision safety of cars is an important issue, and it is necessary to improve the rigidity and strength of the entire vehicle body. In this way, the demand for automobile crash safety in Japan has become increasingly severe, and production of vehicles with higher safety is being demanded.
[0003]
By the way, as a measure to improve the collision safety, each automobile manufacturer has studied the reinforcement structure with steel plate and developed its own body structure, but the weight increase per car (generally 30-50kg) is avoided. Absent.
In addition to such structural reinforcement, a vehicle body member to which a lot of loads such as a collision are applied, for example, a center pillar having a closed cross-section structure and a front pillar having a closed cross-section structure of the front vehicle body, which is mounted with a belt anchor of a seat belt device. A foam-cured foam that functions as a reinforcing material by injecting a two-component foamable material into pillars, etc., into their closed section (usually installing partition partitions to form a closed section) Consideration is being made to fill.
[0004]
This foam-cured foam filling technology takes into account the foaming ratio and other foaming conditions of a two-part foamable material, and injects in a desired range by quantitatively injecting it in an amount commensurate with the volume inside the closed section to be filled. A vehicle body member having a closed cross-sectional structure such as the center pillar or the front pillar filled with the hardened foam can be obtained.
However, when a failure occurs in the injection device or the like as an unexpected situation, it is predicted that if the filling capacity of the foam-cured foam is insufficient below the desired range, a cavity portion is generated and the design strength cannot be obtained. Further, it is conceivable that the filling capacity is insufficient due to an unexpected loss of the partition plate provided in the closed cross section.
Actually, there is no way to prevent such a shortage of filling capacity, and it is currently possible to determine the suitability of the filling capacity for the first time by performing a crash test, measuring the rigidity of the actual vehicle, or analyzing the vibration after the production line. In the middle of the production line, the design strength and rigidity of the car could not be guaranteed.
[0005]
[Means for Solving the Problems]
In order to prevent the problems caused by the shortage of the filling capacity and to provide a vehicle body member having a closed cross-sectional structure in which the foam-cured foam is properly filled and reinforced, and a method for filling the fill-cured foam, As a result of investigations, the installation of a filling confirmation opening with a specific size for confirming the appropriateness of the filling capacity corresponding to the volume inside the closed cross section was established at a specific location of the vehicle body member having a closed cross section structure. The inventors have found that the object can be achieved and have completed the present invention.
[0006]
That is, according to the present invention, a two-component foamable material is injected into a closed cross section of a vehicle body member having a closed cross section structure, and the volume inside the closed cross section is commensurate with a vehicle body member filled with foam cured foam by foam curing. A foam-curing foam-filled vehicle body member characterized in that a filling confirmation opening having a diameter of 10 mm or less is installed in front of the limit position where the foam-curing foam finally reaches in order to confirm the proper filling capacity; In the method of injecting a two-component foamable material into a closed cross section of a vehicle body member having a closed cross-section structure and filling the foam cured foam by foam curing, the limit position where the foam cured foam of the vehicle body member finally reaches By installing a filling confirmation opening with a diameter of 10 mm or less in front of 50 mm from the front, confirm the appropriate filling capacity corresponding to the volume inside the closed section. It is intended to provide a method of filling the foamed cured form, wherein.
[0007]
As a vehicle body member having a closed cross-sectional structure in the present invention, for example, as shown in FIG. 1, a front roof 1 (configured by a roof rail inner and a roof rail outer) and a front side roof rail 2 (configured by a front side outer panel and a side roof rail inner) are shown. Examples include a structural member in which a front pillar 3 (consisting of a front side outer panel and a front pillar inner) is connected, and partition plates 4 and 5 are installed inside the front side roof rail 2 and the front pillar 3, respectively. An injection hole 6 is formed in the side roof rail 2.
Another example is the structural member shown in FIG. 2, which includes a center pillar 7 (consisting of a center pillar inner and a center pillar outer) and a side roof rail 8 (comprising a side roof rail inner and a side roof rail outer). In this connection, partition plates 9, 10, and 11 are installed, and an injection hole 12 is opened.
[0008]
In the present invention, the two-component foamable material to be injected into the injection holes 6 and 12 is not particularly limited as long as it can be foam-cured at room temperature. For example, a polyol main agent [polyhydric alcohol, bisphenol] A polyether polyol obtained by addition reaction of an alkylene oxide with an active hydrogen-containing compound such as various amines, and a polyisocyanate curing agent [aromatic polyisocyanate, aliphatic or cycloaliphatic polyisocyanate, aromatic fat] Group polyisocyanates, various modified products thereof, terminal NCO group-containing urethane prepolymers obtained by reaction of polyols with an excess of polyisocyanate compounds, etc.], and a foaming agent [water, thermal decomposition type chemical foaming on the main agent side] Agents (azodicarbodiamide, p, p'-oxybisbenzenesulfonylhydrazide, etc.), heat Type inorganic foaming agent (sodium bicarbonate, etc.), thermal expansion type microballoon (polymer capsule encapsulating a low boiling point solvent such as pentane, heptane, etc.), etc., and reaction catalyst, chain extender if necessary It is preferable to use a two-component foamable urethane material to which a foam stabilizer, a colorant, a plasticizer, a filler, a flame retardant, an anti-aging agent, an antioxidant and the like are added.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
In the foam cured foam-filled vehicle body member and the foam cured foam filling method according to the present invention, one or more filling confirmation openings are installed at predetermined positions of the structural member as shown in FIGS. It is characterized by. For example, in FIG. 1, when a two-component foam material is injected from the injection hole 6, the foam material first proceeds while being foam-cured toward the front pillar 3, and then spreads to the front side roof rail 2, while the upper end portion and corners are expanded. Around the part, finally proceeding upward of the front roof 1 and reaching the limit position P shown in the figure.
Accordingly, if the filling confirmation opening H is installed within 50 mm, preferably within 1 to 30 mm from the limit position P, it is visually confirmed whether or not the foaming and foaming foam to be formed has insufficient filling capacity. Can be confirmed. In this case, when viewed from the opening H, generally yellow to tan color means passage of the foam-cured foam, and otherwise, a dark black color in a hollow state is indicated.
When the position of the filling confirmation opening H exceeds 50 mm before the limit position P, it is difficult to accurately determine whether or not an appropriate filling capacity has been obtained even after the passage of the foam-cured foam is confirmed.
The diameter of the filling confirmation opening H is set to 10 mm or less, preferably 1 to 7.5 mm. If the diameter exceeds 10 mm, leakage of the foam-cured foam is observed, and it is not desirable from the viewpoint of a decrease in vehicle body rigidity.
From the same viewpoint as the filling confirmation opening H, two filling confirmation openings H 1 and H 2 are also provided in the structural member of FIG.
[0010]
Thus, the installation of the filling confirmation opening allows visual confirmation of the suitability of the filling capacity of the foam-cured foam, and at the same time guarantees the strength and rigidity of the design. In addition, it is possible to avoid the unnecessary production of vehicles that are predicted to be insufficiently filled. However, in the above visual confirmation, if insufficient filling is detected, the filling confirmation opening is filled with, for example, a wire, and the approximate shortage amount is calculated, and then a separate injection hole is provided to replenish the two-component foam material. Injection may be performed.
[0011]
