Description

本発明は、車両のスライドドア用のステップ構造体に関し、とくに、必要な剛性・強度を確保しつつ軽量化をはかった車両スライドドア用ステップ構造体に関する。   The present invention relates to a step structure for a sliding door of a vehicle, and more particularly to a step structure for a sliding door of a vehicle that achieves the required rigidity and strength while reducing the weight.

スライドドアを有する車両においては、スライドドア開口部におけるステップ側パネル（スライドドア開口部の下部側に設けられ、乗降する際に踏台となるパネル）を構成するステップ構造体が設けられ、このステップ構造体の下面側に、スライドドアのドアスライド機構が配置され、ドア開閉のための駆動機構が連結されることが多い（例えば、特許文献１）。   In a vehicle having a slide door, a step structure is provided which constitutes a step side panel (a panel provided on the lower side of the slide door opening and serving as a platform when getting on and off) at the slide door opening. A door slide mechanism of a slide door is disposed on the lower surface side of the body, and a drive mechanism for opening and closing the door is often coupled (for example, Patent Document 1).

従来のステップ構造体は、スチールで構成されており、重量が大きく、また、部品点数も多い。したがって、ステップ構造体の軽量化、部品点数の削減が要求されることが多いが、現行のスチール製のままでは、現状以上の軽量化、部品点数の削減が難しいのが実情である。   The conventional step structure is made of steel, is heavy, and has a large number of parts. Therefore, it is often required to reduce the weight of the step structure and reduce the number of parts. However, it is actually difficult to reduce the weight and reduce the number of parts if the current steel is used.

ステップ構造体の軽量化、部品点数の削減を達成するために、ステップ構造体を樹脂化し、一体成形により作製することも考えられるが、ステップ構造体においては、ステップ側パネルとしての部位に加え、とくにスライドドアを案内するするためのガイドレールの設置部やその近傍部位には、相当高い剛性や強度が求められることから、単に樹脂化するだけではこれらの要求に応えることが困難である。   In order to reduce the weight of the step structure and reduce the number of parts, it is conceivable that the step structure is made of resin and manufactured by integral molding, but in the step structure, in addition to the part as the step side panel, In particular, since the installation portion of the guide rail for guiding the sliding door and its vicinity are required to have considerably high rigidity and strength, it is difficult to meet these requirements simply by making it resin.

また、単なる樹脂ではなく、複合材料、例えばガラス繊維を用いた射出材やＧＭＴ（Glass-Mat reinforced Thermoplastics)でステップ構造体を構成することも考えられるが、このように強化繊維としてガラス繊維を用いた材料では、高い軽量化率と高い剛性・強度を両立させることは、一般的に難しい。   In addition, it is conceivable that the step structure is composed of a composite material, for example, an injection material using glass fiber or GMT (Glass-Mat reinforced Thermoplastics) instead of a resin. In this way, glass fiber is used as the reinforcing fiber. With conventional materials, it is generally difficult to achieve both a high weight reduction ratio and high rigidity and strength.

特開２００７−１３２１４１号公報JP 2007-132141 A

そこで本発明の課題は、高い軽量化効果が得られるとともに、スチール製の場合と同等の剛性および必要な強度を有することが可能な車両スライドドア用ステップ構造体を提供することにある。   Accordingly, an object of the present invention is to provide a step structure for a vehicle sliding door that can obtain a high weight reduction effect and can have the same rigidity and necessary strength as those made of steel.

上記課題を解決するために、本発明に係る車両スライドドア用ステップ構造体は、車両のスライドドアのドアスライド機構の一部を構成するとともに、スライドドア開口部におけるステップ側パネルを構成するステップ構造体において、該ステップ構造体が炭素繊維強化プラスチックから構成されており、該ステップ構造体は、その平面形状の外形に沿って少なくとも部分的に延びる略Ｃ形断面形状の外枠部と、ステップ構造体内において前記外枠部の内側に接続され車両内側から車両外側に向かって延びるように配置された略Ｃ形断面形状の梁部とを有し、かつ、少なくともスライドドアを開閉方向に案内するためのガイドレールがステップ構造体に一体成形されていることを特徴とするものからなる。   In order to solve the above problems, a step structure for a vehicle sliding door according to the present invention constitutes a part of a door sliding mechanism of a sliding door of a vehicle and a step structure constituting a step side panel at an opening of the sliding door. The step structure is made of a carbon fiber reinforced plastic, and the step structure includes an outer frame portion having a substantially C-shaped cross section extending at least partially along an outer shape of the planar shape, and a step structure. A beam portion having a substantially C-shaped cross section connected to the inside of the outer frame portion and extending from the inside of the vehicle toward the outside of the vehicle in the body, and at least for guiding the sliding door in the opening / closing direction The guide rail is integrally formed with the step structure.

このような本発明に係るステップ構造体においては、ステップ構造体が炭素繊維強化プラスチック（以下、ＣＦＲＰ（Carbon Fiber Reinforced Plastic)と呼ぶこともある。）から構成されているので、ガラス繊維強化プラスチックなどから構成される場合に比べ、軽量化を達成しつつ、ＣＦＲＰ自体の特性により、より高い剛性、強度の発現が可能となる。このＣＦＲＰから構成されるステップ構造体は、略Ｃ形断面形状の外枠部と、その外枠部に接続され車両内側から車両外側に向かって延びる略Ｃ形断面形状の梁部とを有するが、これら略Ｃ形断面形状部位では、とくに厚肉部を設けずに、したがって、軽量化を促進しつつ、構造的に高い剛性・強度を確保できる。そして、ステップ構造体は、これら略Ｃ形断面形状を有する外枠部と梁部との接続構造を有する一体成形品に構成されるので、ステップ構造体全体として軽量化を促進しつつ、構造的に、スチール比同等の剛性を保持しながら、必要な強度の発現が可能となる。また、ステップ構造体には、スライドドアを開閉方向に案内するためのガイドレールの設置が求められるが、従来基本的に別部品としてステップ構造体本体に取り付けられていたガイドレール（通常、一対のガイドレール）が、本発明では、ＣＦＲＰ製ステップ構造体に一体成形されているので、ガイドレール付きのＣＦＲＰ製ステップ構造体が成形されることになる。その結果、少なくともガイドレールが別部品として製作されていた場合に比べ、部品点数が削減される。   In such a step structure according to the present invention, the step structure is made of carbon fiber reinforced plastic (hereinafter also referred to as CFRP (Carbon Fiber Reinforced Plastic)). Compared to the case of being constructed from the above, it is possible to achieve higher rigidity and strength due to the characteristics of CFRP itself while achieving weight reduction. The step structure made of CFRP includes an outer frame portion having a substantially C-shaped cross section and a beam portion having a substantially C-shaped cross section that is connected to the outer frame portion and extends from the vehicle inner side toward the vehicle outer side. In these substantially C-shaped cross-sections, it is possible to ensure structurally high rigidity and strength without particularly providing a thick portion and thus promoting weight reduction. Since the step structure is formed as an integrally molded product having a connection structure between the outer frame portion and the beam portion having a substantially C-shaped cross-sectional shape, the step structure as a whole is structurally promoted in weight reduction. In addition, the required strength can be expressed while maintaining the rigidity equivalent to the steel ratio. In addition, the step structure is required to be provided with a guide rail for guiding the sliding door in the opening and closing direction. Conventionally, the guide rail (usually a pair of guide rails, which is conventionally attached to the step structure body as a separate part) In the present invention, since the guide rail is integrally formed with the CFRP step structure, the CFRP step structure with the guide rail is formed. As a result, the number of parts is reduced as compared with the case where at least the guide rail is manufactured as a separate part.

上記本発明に係る車両スライドドア用ステップ構造体においては、ステップ構造体を構成する炭素繊維強化プラスチックのマトリックス樹脂が熱可塑性樹脂からなることが好ましい。マトリックス樹脂として熱硬化性樹脂を使用することも可能ではあるが、ステップ構造体は通常かなり複雑な形状を有しているので、マトリックス樹脂として熱可塑性樹脂を使用することにより、複雑形状の場合にあっても大きな困難性を伴うことなく成形することが可能になる。   In the vehicle sliding door step structure according to the present invention, the matrix resin of the carbon fiber reinforced plastic constituting the step structure is preferably made of a thermoplastic resin. Although it is possible to use a thermosetting resin as the matrix resin, the step structure usually has a fairly complicated shape, so by using a thermoplastic resin as the matrix resin, Even if it exists, it becomes possible to shape | mold without a big difficulty.

また、本発明に係る車両スライドドア用ステップ構造体においては、ステップ構造体を構成する炭素繊維強化プラスチックの強化繊維に炭素繊維の短繊維が使用されていることが好ましい。ただし本発明において、短繊維とは、長さ３０ｍｍ以下の繊維のことをいう。このような短繊維はマトリックス樹脂と複合された場合に、マトリックス樹脂とともに流動する性能が高く、高い流動性によって、より均質なＣＦＲＰの成形が可能になるとともに、複雑形状への一体成形が行いやすくなる。   Moreover, in the vehicle slide door step structure according to the present invention, it is preferable that carbon fiber short fibers are used as the reinforcing fibers of the carbon fiber reinforced plastic constituting the step structure. However, in the present invention, the short fiber means a fiber having a length of 30 mm or less. When such short fibers are combined with a matrix resin, the ability to flow with the matrix resin is high, and the high fluidity makes it possible to form a more uniform CFRP and facilitates integral molding into complex shapes. Become.

また、本発明に係る車両スライドドア用ステップ構造体においては、ステップ構造体が、さらに、車体への取付け用ボス部を有し、該取付け用ボス部もステップ構造体に一体成形されている構造を採用することができる。ステップ構造体を車体に取り付けるには、通常、何らかのボス状取付け用部材が必要となるが、この車体への取付け用ボス部もステップ構造体に一体成形しておくことにより、取り付け作業が簡素化されるとともに、取り付け部も含めた全体としての部品点数がより削減される。   In the vehicle sliding door step structure according to the present invention, the step structure further includes a boss portion for attachment to the vehicle body, and the attachment boss portion is also integrally formed with the step structure. Can be adopted. In order to attach the step structure to the vehicle body, some kind of boss-like mounting member is usually required, but the mounting work is simplified by forming the boss part for attachment to the vehicle body integrally with the step structure. In addition, the number of parts as a whole including the mounting portion is further reduced.

さらに、本発明に係る車両スライドドア用ステップ構造体においては、ステップ構造体が、さらに、上記ドアスライド機構に設けられスライドドアを開閉方向に駆動する索状体を案内するための案内板を有し、該周回ベルトの案内板もステップ構造体に一体成形されている構造を採用することもできる。このように、ガイドレールに加え、その他の周辺部品までステップ構造体に一体成形することで、より一層部品点数を削減することが可能になる。   Further, in the vehicle slide door step structure according to the present invention, the step structure further includes a guide plate for guiding a cord-like body that is provided in the door slide mechanism and drives the slide door in the opening / closing direction. In addition, it is possible to adopt a structure in which the guide plate of the circulating belt is also integrally formed with the step structure. In this way, by integrally molding the step structure with other peripheral parts in addition to the guide rail, the number of parts can be further reduced.

本発明に係る車両スライドドア用ステップ構造体によれば、ステップ構造体をＣＦＲＰから構成し、略Ｃ形断面形状の外枠部と梁部とを設けるとともにそれらを接続し、しかも、少なくともガイドレールまでステップ構造体に一体成形するようにしたので、ステップ構造体に求められる必要最小限の機能を満足させつつ、ガイドレールまで含めたステップ構造体全体の望ましい軽量化と、スチール比同等の剛性を保持しながら必要な強度を確保することができ、さらに一体成形により部品点数の大幅な削減が可能になる。例えば、スチール比同等の剛性・強度を確保しつつ、スチール比５０％もの軽量化が可能となる。   According to the vehicle sliding door step structure according to the present invention, the step structure is made of CFRP, the outer frame portion and the beam portion having a substantially C-shaped cross section are provided and connected, and at least the guide rail Since the step structure is integrally molded, the desired weight reduction of the entire step structure including the guide rail and the rigidity equivalent to the steel ratio are achieved while satisfying the minimum required functions required for the step structure. The required strength can be ensured while holding, and the number of parts can be greatly reduced by integral molding. For example, it is possible to reduce the weight of steel by 50% while ensuring rigidity and strength equivalent to steel.

以下に、本発明の望ましい実施の形態について、図面を参照しながら説明する。
まず図１に、本発明による車両スライドドア用ステップ構造体の車両搭載位置を例示する。図１に示す車両１においては、その側部に、矢印で示す車両前方側、車両後方側に向けてのスライドにより開閉されるスライドドア２が設けられている。スライドドア開口部３には、スライドドア２のドアスライド機構４の一部を構成するとともに、スライドドア開口部３において下側のステップ側パネルを構成するステップ構造体５が配置、固定されている。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
First, FIG. 1 illustrates a vehicle mounting position of a vehicle sliding door step structure according to the present invention. In the vehicle 1 shown in FIG. 1, a slide door 2 that is opened and closed by sliding toward the vehicle front side and the vehicle rear side indicated by arrows is provided on the side portion thereof. In the sliding door opening 3, a part of the door sliding mechanism 4 of the sliding door 2 and a step structure 5 constituting a lower step side panel in the sliding door opening 3 are arranged and fixed. .

このステップ構造体５は、例えば、図２〜図６に示すように構成されている。図２（Ａ）は、ステップ構造体５を上面側（ステップ面側）から見た斜視図、図２（Ｂ）は、ステップ構造体５を下面側から見た斜視図、図３はステップ構造体５を上面側から見た平面図を、それぞれ示している。   This step structure 5 is configured, for example, as shown in FIGS. 2A is a perspective view of the step structure 5 viewed from the upper surface side (step surface side), FIG. 2B is a perspective view of the step structure 5 viewed from the lower surface side, and FIG. 3 is the step structure. The top view which looked at the body 5 from the upper surface side is shown, respectively.

ステップ構造体５は、図２〜図６に示されている部分の全体が、炭素繊維強化プラスチック（ＣＦＲＰ）の一体成形品として構成されている。この一体成形は、例えば、いわゆるシート抄造法と同様の方法で行うことができる。例えば、炭素繊維の短繊維と熱可塑性樹脂からなるマトリックス樹脂とを複合したシート状基材原料を、所定の温度に加熱した状態にて、金型からなる下型の所定形状に形成されたキャビティ内に配置し、上型を閉じてプレス圧を加え、キャビティ内で複合材料を流動させる。自然放冷または強制冷却を行って樹脂を硬化させた後、成形品を脱型する。また上述したようなプレス成形に限らず、射出成形などの方法によっても成形することが可能である。なお、炭素繊維とマトリックス樹脂との複合材料においては、成形すべきステップ構造体５の全体に対して炭素繊維の短繊維を用いてもよく、意図的に、一部の成形箇所に対しては長繊維（前述した短繊維よりも長い繊維）または連続繊維からなる炭素繊維を使用し、残りの成形箇所に対して炭素繊維の短繊維を用いるようにすることも可能である。長繊維または連続繊維からなる炭素繊維は、より剛性・強度を向上したい部位に配置すればよい。   The entire structure of the step structure 5 shown in FIGS. 2 to 6 is configured as an integrally molded product of carbon fiber reinforced plastic (CFRP). This integral molding can be performed, for example, by a method similar to a so-called sheet making method. For example, a cavity formed in a predetermined shape of a lower mold made of a mold in a state where a sheet-like base material made by combining a short fiber of carbon fiber and a matrix resin made of a thermoplastic resin is heated to a predetermined temperature It is placed inside, the upper die is closed, press pressure is applied, and the composite material flows in the cavity. After natural cooling or forced cooling to cure the resin, the molded product is demolded. Further, the present invention is not limited to press molding as described above, and can be molded by a method such as injection molding. In the composite material of carbon fiber and matrix resin, short fibers of carbon fiber may be used for the entire step structure 5 to be molded. It is also possible to use carbon fibers made of long fibers (fibers longer than the short fibers described above) or continuous fibers, and use the short fibers of carbon fibers for the remaining molding locations. Carbon fibers made of long fibers or continuous fibers may be disposed at a site where it is desired to improve rigidity and strength.

このように全体として一体成形されたステップ構造体５は、図２、図３に示すように、ステップ構造体５の平面形状の外形に沿って少なくとも部分的に延びる略Ｃ形断面形状の外枠部１１と、ステップ構造体５内において外枠部１１の内側（部材内の内側）に接続され、矢印で示す車両内側から車両外側に向かって延びるように配置された略Ｃ形断面形状の梁部１２とを有している。さらに、スライドドア２を開閉方向に案内するためのガイドレール１３（一対のレール構造を有するガイドレール）が、このステップ構造体５に一体成形されている。   As shown in FIGS. 2 and 3, the step structure 5 integrally formed as a whole as described above has a substantially C-shaped outer frame extending at least partially along the planar shape of the step structure 5. A beam having a substantially C-shaped cross section that is connected to the inside of the outer frame 11 (inside the member) in the step structure 5 and to extend from the vehicle inside to the vehicle outside as indicated by an arrow. Part 12. Further, a guide rail 13 (guide rail having a pair of rail structures) for guiding the slide door 2 in the opening / closing direction is integrally formed with the step structure 5.

また、本実施態様では、ステップ構造体５には、さらに、車体への取付け用ボス部１４が、複数、一体成形されている。さらに、ステップ構造体５には、ドアスライド機構に設けられスライドドア２を開閉方向に駆動する周回ベルトやケーブル等からなる索状体（図示略）を案内するために使用される索状体用案内板１５も、一体成形されている。   Further, in this embodiment, the step structure 5 is further integrally formed with a plurality of boss portions 14 for attachment to the vehicle body. Further, the step structure 5 is provided for a cord-like body used for guiding a cord-like body (not shown) that is provided in the door slide mechanism and that is configured to drive the slide door 2 in the opening / closing direction and is composed of a revolving belt or a cable. The guide plate 15 is also integrally formed.

上記の略Ｃ形断面形状の外枠部１１、略Ｃ形断面形状の梁部１２の形態をより明確に示すために、図３のＡ−Ａ断面図、Ｂ−Ｂ断面図、Ｃ−Ｃ断面図を、図４、図５、図６に示す。略Ｃ形断面形状の外枠部１１は、本実施態様に示すように、ステップ構造体５の平面形状の外形の全周に沿って延びているのではなく、ステップ構造体５の平面形状の外形に沿って部分的に延びており、図６に示すように、略Ｃ形断面形状の外枠部１１ではなく、単なる一定厚みの外枠部１６に形成されている箇所もある。   In order to more clearly show the form of the outer frame portion 11 having the substantially C-shaped cross section and the beam portion 12 having the substantially C-shaped cross section, the AA cross-sectional view, BB cross-sectional view, and CC cross-sectional view of FIG. Cross-sectional views are shown in FIGS. 4, 5, and 6. As shown in the present embodiment, the outer frame portion 11 having a substantially C-shaped cross section does not extend along the entire circumference of the planar shape of the step structure 5, but has a planar shape of the step structure 5. As shown in FIG. 6, there is a portion formed not on the outer frame portion 11 having a substantially C-shaped cross section but on the outer frame portion 16 having a mere constant thickness.

このように構成されたステップ構造体５においては、ＣＦＲＰから構成されることにより、ガラス繊維強化プラスチックなどから構成される場合に比べ、軽量化を達成しつつ、ＣＦＲＰ自体の物性により、より高い剛性、強度の発現が可能となる。つまり、望ましい状態にて、軽量化と高い剛性、強度の両立が可能となる。とくに、外枠部１１の略Ｃ形断面形状によりステップ構造体５の外縁部が少なくとも部分的に強化され、梁部１２を配置してその断面形状を略Ｃ形断面形状とすることにより、ステップ構造体５の部材内部の剛性・強度が向上され、これら略Ｃ形断面形状の外枠部１１と車両内側から車両外側に向かって延びる略Ｃ形断面形状の梁部１２とを接続した構造により、ステップ構造体５全体としての剛性・強度が大幅に向上される。しかも、このような略Ｃ形断面形状部位では、とくに厚肉部を形成することなく、比較的薄肉にて断面形状的に剛性・強度の向上を達成できるから、軽量化を促進しつつ、構造的に高い剛性・強度を確保できるようになる。その結果、従来のスチール製のステップ構造体に比べ、大幅な軽量化を達成しつつ、スチール比同等の剛性を確保でき、必要な強度を発現できる。   The step structure 5 configured as described above is made of CFRP, so that it is lighter than the case of glass fiber reinforced plastic or the like, and has higher rigidity due to the physical properties of the CFRP itself. , Strength can be expressed. That is, in a desirable state, it is possible to achieve both weight reduction and high rigidity and strength. In particular, the outer edge portion of the step structure 5 is at least partially reinforced by the substantially C-shaped cross-sectional shape of the outer frame portion 11, and the step is performed by arranging the beam portion 12 to make the cross-sectional shape a substantially C-shaped cross-sectional shape. The structure 5 has improved rigidity and strength inside the member, and has a structure in which the outer frame portion 11 having a substantially C-shaped cross section and the beam portion 12 having a substantially C-shaped cross section extending from the vehicle inner side toward the vehicle outer side are connected. The rigidity and strength of the step structure 5 as a whole are greatly improved. Moreover, in such a substantially C-shaped cross-section portion, it is possible to achieve improvement in rigidity and strength in a cross-sectional shape with a relatively thin wall without particularly forming a thick-walled portion. High rigidity and strength can be secured. As a result, compared to the conventional steel step structure, it is possible to secure a rigidity equivalent to the steel ratio while achieving a significant weight reduction, and to exhibit the necessary strength.

また、ガイドレール１３が、さらには車体への取り付け用ボス部１４、周回ベルト用案内板１５まで、ステップ構造体５に一体成形されているので、部品点数の大幅な削減が可能となり、組み付け作業性の向上も可能となる。   In addition, since the guide rail 13 is integrally formed with the step structure 5 up to the boss 14 for attachment to the vehicle body and the guide plate 15 for the circulating belt, the number of parts can be greatly reduced, and the assembling work It is also possible to improve the performance.

さらに、マトリックス樹脂として熱可塑性樹脂を使用することにより、複雑な形状を有するステップ構造体５を、とくに困難性を伴うことなく一体成形することが可能になる。また、前述したように、上型、下型からなる成形型のキャビティ内で一体成形とすることにより、射出成形等の場合に比べ、成形品質の向上、材料の歩留りの改善を狙うことが可能になる。   Furthermore, by using a thermoplastic resin as the matrix resin, the step structure 5 having a complicated shape can be integrally formed without any particular difficulty. In addition, as described above, it is possible to aim to improve molding quality and material yield compared to injection molding, etc., by performing integral molding in the cavity of the molding die consisting of the upper die and the lower die. become.

本発明に係る車両スライドドア用ステップ構造体は、スライドドアを備えたあらゆる車両に対して適用できる。   The vehicle sliding door step structure according to the present invention can be applied to any vehicle having a sliding door.
