Description

車両用サンルーフパネルSunroof panels for vehicles
　本発明は、車両用サンルーフパネルに関し、とくに、軽量化を達成しつつ十分に高い剛性を持たせた車両用サンルーフパネルに関する。 The present invention relates to a vehicle sunroof panel, and more particularly, to a vehicle sunroof panel having sufficiently high rigidity while achieving weight reduction.
　車体の上部開口に装着されるサンルーフパネルは、従来、ガラス製のパネルと、その周縁に沿って設けられた金属製のフレームで構成されたものが一般的なものであった。この金属製フレームは、車体側への装着構造を構成したり、それを構成しやすくするために設けられているとともに、車両走行時にサンルーフパネルにパネルを車体内部側から外部側へ向けて押し上げるように作用する押し上げ力によるパネルの変形を抑える機能を有している。近年、車両全体の軽量化のためにサンルーフパネルに対しても軽量化が要求され、ガラス製パネルをポリカーボネートなどの樹脂から構成したものや、金属製フレームを樹脂から構成したものが提案され始めている。 Conventionally, the sunroof panel mounted on the upper opening of the vehicle body is generally composed of a glass panel and a metal frame provided along the periphery thereof. This metal frame is provided to configure the mounting structure on the vehicle body side or to make it easier to configure, and to push up the panel on the sunroof panel from the vehicle body inner side to the outer side when the vehicle is traveling The panel has a function of suppressing the deformation of the panel due to the pushing force acting on the. In recent years, the weight of the sunroof panel has been required to reduce the overall weight of the vehicle, and glass panels made of resin such as polycarbonate and metal frames made of resin have begun to be proposed. .
　ガラス製パネルを樹脂製パネルにすると大きな軽量化効果が得られるが、樹脂製パネル自体はガラス製パネルに比べ剛性（面剛性）が低いため、上記のような押し上げ力による樹脂製パネルの変形を小さく抑えるためには、パネル周縁に沿って設けられるフレームにはより高い剛性が求められることになり、少なくともフレームの金属製構造をそのまま残す必要があるか、金属製フレームの剛性をより高める必要があり、いずれにしても金属製フレームを使用する限りサンルーフパネル全体の軽量化には限界を生じることになる。 If a glass panel is replaced with a resin panel, a large weight reduction effect can be obtained. However, since the resin panel itself has a lower rigidity (surface rigidity) than a glass panel, the resin panel can be deformed by the above-mentioned pushing force. In order to keep it small, the frame provided along the periphery of the panel is required to have higher rigidity, and at least the metal structure of the frame needs to be left as it is or the rigidity of the metal frame needs to be further increased. In any case, as long as a metal frame is used, there is a limit to reducing the weight of the entire sunroof panel.
　サンルーフパネル全体の軽量化のために、ガラス製パネルを樹脂製パネルにした上で、従来の金属製フレームを樹脂製フレームにすることも考えられるが、単に従来の高い剛性を有するガラス製パネルの場合を想定して設計されていた金属製フレーム形状のままで樹脂化すると、フレームの剛性が不足し、サンルーフパネルの変形を小さく抑えることは難しい。とくに、車両前後方向におけるパネルの変形を小さく抑えることが難しい。すなわち、サンルーフパネルは一般的に車両前後方向における長さよりも車両幅方向における長さの方が長い形状を有しているので、前述のような押し上げ力によるパネルの変形を抑えるために、変形量が大きくなりやすい車両幅方向における変形に対しては、従来の金属製フレームにおいても車両幅方向に延びる補強構造（例えば、補強横断面形状）が採用されていた。したがって、そのような金属製フレームの形状をそのまま採用して樹脂製フレームにした場合、車両幅方向におけるパネル変形についてはその補強構造によりある程度抑えることは可能であるが、そのような補強構造のない車両前後方向に対しては、その方向におけるパネル変形を小さく抑えることは極めて困難である。金属製フレームは元々ガラス製パネルの場合を想定して設計されており、車両前後方向における変形の抑制に関しては、その方向には長さの短いガラス製パネル自体の剛性に大きく頼っていたので、この方向に対してはリブ等の補強構造を考慮する必要がなかったと言え、さらに、必要があったとしても、金属製ではリブ等を立てるのは困難なことが多い。 In order to reduce the weight of the entire sunroof panel, it is conceivable to replace the conventional metal frame with a resin frame after making the glass panel into a resin panel. If the resin is made in the shape of a metal frame designed for the case, the rigidity of the frame is insufficient, and it is difficult to suppress the deformation of the sunroof panel. In particular, it is difficult to reduce the deformation of the panel in the vehicle longitudinal direction. That is, since the sunroof panel generally has a shape that is longer in the vehicle width direction than in the vehicle front-rear direction, the amount of deformation is limited in order to suppress the deformation of the panel due to the pushing-up force as described above. For the deformation in the vehicle width direction, in which the deformation tends to be large, a reinforcing structure (for example, a reinforcing cross-sectional shape) extending in the vehicle width direction has been adopted even in a conventional metal frame. Therefore, when such a metal frame shape is adopted as it is to make a resin frame, panel deformation in the vehicle width direction can be suppressed to some extent by the reinforcing structure, but there is no such reinforcing structure. For the vehicle front-rear direction, it is extremely difficult to keep panel deformation in that direction small. The metal frame was originally designed assuming the case of a glass panel, and for restraining deformation in the longitudinal direction of the vehicle, because it relied heavily on the rigidity of the short glass panel itself in that direction, It can be said that there is no need to consider a reinforcing structure such as a rib in this direction, and even if necessary, it is often difficult to make a rib or the like made of metal.
　上記のような変形抑制の困難性のためか、従来、ガラス製パネルを樹脂製パネルにした上で、フレーム部材を樹脂のみから構成したものは見当たらない。ただし、鋼板からなる取付部材で補強した樹脂製フレーム部材（例えば、特許文献１）や、金属等からなるインサート片で補強した樹脂製フレーム部材（例えば、特許文献２）は知られている。しかしこのように補強された樹脂製フレーム部材の構造では、軽量化をはかる上で限界が生じる。また、これら特許文献１、２では、上述したような車両前後方向におけるパネル変形の抑制の困難性については、言及されていない。 Due to the difficulty of suppressing deformation as described above, there is no conventional structure in which the glass panel is made of a resin and the frame member is made of resin alone. However, a resin frame member reinforced with an attachment member made of a steel plate (for example, Patent Document 1) and a resin frame member reinforced with an insert piece made of metal or the like (for example, Patent Document 2) are known. However, the structure of the resin frame member reinforced in this way has a limit in reducing the weight. Further, these Patent Documents 1 and 2 do not mention the difficulty of suppressing panel deformation in the vehicle longitudinal direction as described above.

　本発明の課題は、大幅な軽量化を達成しつつ、車両幅方向のみならず車両前後方向におけるパネル変形を小さく抑えることのできる十分に高い剛性を持つフレームを備えた車両用サンルーフパネルを提供することにある。 An object of the present invention is to provide a vehicle sunroof panel including a frame having a sufficiently high rigidity that can suppress panel deformation not only in the vehicle width direction but also in the vehicle front-rear direction while achieving significant weight reduction. There is.
　上記課題を解決するために、本発明に係る車両用サンルーフパネルは、樹脂製のパネルと、該パネルに固着され該パネルの周縁に沿って車両幅方向と車両前後方向に延びる部位を有するＦＲＰ製のフレームとからなり、前記フレームの車両前後方向に延びる部位に、該部位の車両前後方向における曲げ剛性を高める車両前後方向に延びる補強部材が設けられていることを特徴とするものからなる。 In order to solve the above-described problems, a vehicle sunroof panel according to the present invention is made of FRP having a resin panel and a portion that is fixed to the panel and extends in the vehicle width direction and the vehicle front-rear direction along the periphery of the panel. And a reinforcing member extending in the vehicle front-rear direction is provided at a portion of the frame extending in the vehicle front-rear direction to increase the bending rigidity of the portion in the vehicle front-rear direction.
　このような本発明に係る車両用サンルーフパネルにおいては、樹脂製パネルの周縁に沿って延びるフレームが、ＦＲＰから構成されているので、樹脂のみからなるフレームに比べ、極めて高い剛性を有し、該ＦＲＰ製フレームが固着されている樹脂製パネルの変形を十分に小さく抑えることが可能になる。そして、とくに、上記ＦＲＰ製フレームの車両前後方向に延びる部位に、該部位の車両前後方向における曲げ剛性を高める車両前後方向に延びる補強部材が設けられているので、該フレームの車両前後方向に延びる部位の曲げ剛性が的確に効率よく高められ、車両前後方向における樹脂製パネルの変形が効率よく小さく抑えられることになる。このようなＦＲＰ製フレームは、従来の金属製補強材を組み込んだ樹脂製フレームに比べても、高剛性を維持しながら十分に軽く構成可能であるので、フレームの軽量化、ひいては樹脂製パネルと併せてサンルーフパネル全体の大幅な軽量化が可能になる。 In such a vehicle sunroof panel according to the present invention, since the frame extending along the periphery of the resin panel is made of FRP, it has extremely high rigidity compared to a frame made only of resin, The deformation of the resin panel to which the FRP frame is fixed can be suppressed sufficiently small. In particular, a reinforcing member extending in the vehicle front-rear direction is provided at a portion of the FRP frame extending in the vehicle front-rear direction so as to increase the bending rigidity of the portion in the vehicle front-rear direction, so that the frame extends in the vehicle front-rear direction. The bending rigidity of the portion is accurately and efficiently increased, and the deformation of the resin panel in the vehicle front-rear direction is efficiently suppressed to a small size. Such an FRP frame can be configured to be light enough while maintaining high rigidity, compared to a conventional resin frame incorporating a metal reinforcing material. In addition, the entire sunroof panel can be significantly reduced in weight.
　また、本発明に係る車両用サンルーフパネルにおいては、上記フレームの車両前後方向に延びる部位に、上記補強部材が一体に設けられている構造を採ることができる。このような構造の採用は、金属製フレームの場合には難しかったが、ＦＲＰ製フレームはそのマトリックス樹脂の型内への流動を利用して成形できるので、容易にフレーム面上等に補強部材を設けることが可能である。車両前後方向に延びる補強部材を一体に設けることにより、フレームの車両前後方向に延びる部位の曲げ剛性が少ない素材量で効率よく高められ、車両前後方向における樹脂製パネルの変形が効率よく小さく抑えられることになる。この補強部材の形態は、フレーム面上から単に板状の補強部材が立ち上がる構造でもよく、横断面形状的により高い剛性を有する形態の補強部材が車両前後方向に延びる構造としてもよい。 In the vehicle sunroof panel according to the present invention, a structure in which the reinforcing member is integrally provided at a portion of the frame extending in the vehicle front-rear direction can be employed. The adoption of such a structure was difficult in the case of a metal frame, but the FRP frame can be molded by utilizing the flow of the matrix resin into the mold, so that a reinforcing member can be easily placed on the frame surface or the like. It is possible to provide. By integrally providing the reinforcing member extending in the vehicle longitudinal direction, the bending rigidity of the portion of the frame extending in the vehicle longitudinal direction can be efficiently increased with a small amount of material, and the deformation of the resin panel in the vehicle longitudinal direction can be efficiently suppressed to a small level. It will be. The form of this reinforcing member may be a structure in which a plate-like reinforcing member rises from the frame surface, or a structure in which a reinforcing member having a higher rigidity in the cross-sectional shape extends in the vehicle front-rear direction.
　サンルーフパネルは、前述したように、通常、車両前後方向における長さよりも車両幅方向における長さの方が長い平面形状を有しているので、フレームの車両幅方向に延びる部位には、この方向における樹脂製パネルの変形を十分に小さく抑える構造が採られていることが好ましい。従来の金属製フレームの場合にあっても、このような構造は採用されていたので、樹脂製パネルとＦＲＰ製フレームとを組み合わせた本発明に係る車両用サンルーフパネルにおいても、そのような構造が採用されることが好ましい。例えば、上記ＦＲＰ製フレームの車両幅方向に延びる部位に、断面の形状（横断面の形状）によって該部位の車両幅方向における曲げ剛性を高める車両幅方向に延びる高剛性構造部が設けられていることが好ましい。ここで、「高剛性構造部」の「高剛性」とは、断面視にて一部がハット形等の凹凸状に隆起あるいは屈曲している部位を有することで、そのような部位を有していない場合に比べて高剛性であることをいう。例えば、横断面形状がハット形や箱形、Ｚ形、Ｉ形等に形成された、車両幅方向に延びる高剛性構造部を設けることができ、このような高剛性構造部によって、ＦＲＰ製フレームの車両幅方向における曲げ剛性が大幅に高められる。 As described above, the sunroof panel usually has a planar shape in which the length in the vehicle width direction is longer than the length in the vehicle front-rear direction. It is preferable to adopt a structure in which the deformation of the resin panel is sufficiently reduced. Even in the case of a conventional metal frame, such a structure has been adopted. Therefore, such a structure is also applied to the vehicle sunroof panel according to the present invention in which a resin panel and an FRP frame are combined. It is preferable to be adopted. For example, a high-rigidity structure portion extending in the vehicle width direction is provided at a portion extending in the vehicle width direction of the FRP frame so as to increase the bending rigidity in the vehicle width direction of the portion by the shape of the cross section (the shape of the cross section). It is preferable. Here, “high rigidity” of “high rigidity structure” means that a part of the structure is raised or bent in an uneven shape such as a hat shape in a cross-sectional view. This means that it is more rigid than if it is not. For example, a high-rigidity structure portion extending in the vehicle width direction and having a cross-sectional shape formed into a hat shape, a box shape, a Z shape, an I shape, or the like can be provided. The bending rigidity in the vehicle width direction is greatly increased.
　また、前述したように、ＦＲＰ製フレームの車両前後方向に延びる部位に車両前後方向に延びる補強部材を設けることにより、フレームの車両前後方向における曲げ剛性を高めることができるが、この補強部材が、上記車両幅方向に延びる高剛性構造部に接続されていると、補強部材と高剛性構造部とで互いに直交する枠組み構造を形成できるので、一層高い剛性を発現させることが可能になる。とくに、元来高い剛性を持つように設計されている高剛性構造部の高い剛性を補強部材側に波及させることができ、単に板状の立設補強部材であっても、その補強部材に容易に望ましい高剛性を付与することが可能になって、車両前後方向におけるパネル変形が一層効率よく小さく抑えられることになる。 In addition, as described above, by providing a reinforcing member extending in the vehicle front-rear direction in the portion of the FRP frame extending in the vehicle front-rear direction, the bending rigidity of the frame in the vehicle front-rear direction can be increased. When connected to the high-rigidity structure portion extending in the vehicle width direction, a frame structure orthogonal to each other can be formed by the reinforcing member and the high-rigidity structure portion, so that higher rigidity can be expressed. In particular, the high rigidity of the high rigidity structural part originally designed to have high rigidity can be propagated to the reinforcing member side, and even a plate-like standing reinforcing member can be easily applied to the reinforcing member. The desired high rigidity can be imparted to the vehicle, and the panel deformation in the vehicle front-rear direction can be more effectively suppressed and reduced.
　また、車両用サンルーフパネルにおいては、車体側への装着、脱着のために、フレームの車両前後方向に延びる部位に、車体側への取付部を設けることがあるが、このような取付部に前述の車両前後方向に延びる補強部材が接続されていると、取付部の剛性と補強部材の剛性を相乗的に高めることが可能になり、その補強部材に容易に望ましい高剛性を付与することが可能になって、車両前後方向におけるパネル変形が一層効率よく小さく抑えられることになる。 In addition, in a vehicle sunroof panel, an attachment portion to the vehicle body side may be provided at a portion extending in the vehicle front-rear direction of the frame for attachment to and removal from the vehicle body side. When a reinforcing member extending in the vehicle longitudinal direction is connected, it is possible to synergistically increase the rigidity of the mounting portion and the rigidity of the reinforcing member, and it is possible to easily impart the desired high rigidity to the reinforcing member. Thus, the panel deformation in the vehicle front-rear direction can be more effectively suppressed and reduced.
　上記のような車両前後方向に延びる補強部材は、複数設けることができる。複数設けることにより、ＦＲＰ製フレームの車両前後方向に延びる部位の剛性がさらに高められる。とくに、該部位を全体にわたって高剛性化でき、剛性的に問題を生じるような部分の発生を防止できる。このように効率よく高剛性化されたＦＲＰ製フレームの車両前後方向に延びる部位によって、車両前後方向におけるパネル変形が一層小さく抑えられる。 A plurality of reinforcing members extending in the vehicle front-rear direction as described above can be provided. By providing a plurality, the rigidity of the portion of the FRP frame extending in the vehicle front-rear direction is further enhanced. In particular, it is possible to increase the rigidity of the entire part and prevent the occurrence of a part that causes a problem in rigidity. The panel extending in the vehicle front-rear direction is further suppressed by the portion extending in the vehicle front-rear direction of the frame made of FRP that is efficiently and highly rigid in this way.
　上述した補強部材は、例えば、リブの形態に構成することができる。ＦＲＰ製フレームに対し、上記補強部材がリブの形態とされることにより、所望の補強部材を容易に形成することが可能になり、とくにＦＲＰ製フレームと容易に一体成形することが可能になる。 The reinforcing member described above can be configured in the form of a rib, for example. When the reinforcing member is in the form of a rib with respect to the FRP frame, a desired reinforcing member can be easily formed, and in particular, it can be easily formed integrally with the FRP frame.
　本発明においては、上記フレームのＦＲＰは、とくに、強化繊維と熱可塑性樹脂からなることが好ましい。マトリックス樹脂に熱可塑性樹脂を用いることにより、射出成形が可能になるので、高い生産性をもって大量生産することが可能になる。マトリックス樹脂として使用する熱可塑性樹脂としては、とくに限定されず、使用可能な樹脂を例示すると、ポリアミド（ナイロン６、ナイロン６６等）、ポリオレフィン（ポリエチレン、ポリプロピレン等）、ポリエステル（ポリエチレンテレフタレート、ポリブチレンテレフタレート等）、ポリカーボネート、ポリアミドイミド、ポリフェニレンサルファイド、ポリフェニレンオキシド、ポリスルホン、ポリエーテルスルホン、ポリエーテルエーテルケトン、ポリエーテルケトンケトン、ポリエーテルイミド、ポリスチレン、ＡＢＳ、液晶ポリエステルや、アクリロニトリルとスチレンの共重合体等を挙げることができる。これらの混合物でもよい。また、ナイロン６とナイロン６６との共重合ナイロンのように共重合したものであってもよい。さらに得たい成形品の要求特性に応じて、難燃剤、耐候性改良剤、その他酸化防止剤、熱安定剤、紫外線吸収剤、可塑剤、滑剤、着色剤、相溶化剤、導電性フィラー等を添加しておくことができる。また、強化繊維の種類としては、とくに限定されず、炭素繊維やガラス繊維、アラミド繊維など、さらにはこれらを組み合わせたハイブリッド構成の強化繊維の使用が可能である。 In the present invention, the FRP of the frame is particularly preferably made of reinforcing fibers and a thermoplastic resin. By using a thermoplastic resin as the matrix resin, it becomes possible to perform injection molding, so that mass production with high productivity becomes possible. The thermoplastic resin used as the matrix resin is not particularly limited, and examples of usable resins include polyamide (nylon 6, nylon 66, etc.), polyolefin (polyethylene, polypropylene, etc.), polyester (polyethylene terephthalate, polybutylene terephthalate). Etc.), polycarbonate, polyamideimide, polyphenylene sulfide, polyphenylene oxide, polysulfone, polyether sulfone, polyether ether ketone, polyether ketone ketone, polyether imide, polystyrene, ABS, liquid crystal polyester, acrylonitrile and styrene copolymer, etc. Can be mentioned. A mixture of these may also be used. Moreover, what was copolymerized like the copolymer nylon of nylon 6 and nylon 66 may be used. Furthermore, depending on the required properties of the molded product to be obtained, flame retardants, weather resistance improvers, other antioxidants, heat stabilizers, UV absorbers, plasticizers, lubricants, colorants, compatibilizers, conductive fillers, etc. It can be added. Further, the type of the reinforcing fiber is not particularly limited, and carbon fiber, glass fiber, aramid fiber, and the like, or a reinforcing fiber having a hybrid configuration in which these are combined can be used.
　とくに、上記強化繊維と熱可塑性樹脂からなるＦＲＰの強化繊維に短繊維が使用されていると、上述したような高剛性構造部や補強部材などを有し、部分的に比較的複雑な形状を有する場合にあっても、比較的容易に前記ＦＲＰ製フレームを射出成形することが可能になる。 In particular, when short fibers are used for the reinforcing fiber of FRP made of the above reinforcing fiber and thermoplastic resin, it has a high-rigidity structure part or a reinforcing member as described above, and has a relatively complicated shape partially. Even in such a case, the FRP frame can be injection molded relatively easily.
　このように、本発明に係る車両用サンルーフパネルによれば、従来のガラス製パネルを樹脂製パネルにした上で、フレーム部材をＦＲＰ製フレームから構成し、かつ、ＦＲＰ製フレームの車両前後方向に延びる部位に補強部材を設けたので、サンルーフパネル全体の大幅な軽量化を達成できるとともに、フレーム部材に車両幅方向のみならず車両前後方向におけるパネル変形を十分に小さく抑えることができるだけの剛性を容易に付与できるようになり、軽量化とパネル変形抑制とをともに達成可能となる。また、とくに特定の設置形態の補強部材を設ければ、パネル変形抑制のための望ましい剛性をより確実に達成できる。さらに、ＦＲＰ製フレームのマトリックス樹脂に熱可塑性樹脂を使用することにより、さらには強化繊維に短繊維を使用することにより、所望のＦＲＰ製フレームを容易に射出成形することが可能になり、大量生産にも対応できるようになる。 As described above, according to the vehicle sunroof panel according to the present invention, the conventional glass panel is made of a resin panel, the frame member is composed of the FRP frame, and the FRP frame is arranged in the vehicle front-rear direction. Since the reinforcing member is provided at the extended part, the overall weight of the sunroof panel can be significantly reduced, and the frame member can be easily rigid enough to suppress panel deformation not only in the vehicle width direction but also in the vehicle longitudinal direction. Thus, both weight reduction and panel deformation suppression can be achieved. In particular, if a reinforcing member having a specific installation form is provided, a desirable rigidity for suppressing panel deformation can be achieved more reliably. Furthermore, by using a thermoplastic resin for the matrix resin of the FRP frame, and by using short fibers for the reinforcing fibers, it becomes possible to easily injection-mold the desired FRP frame for mass production. It will be possible to respond to.

　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。
　図１は、本発明の適用対象となるサンルーフパネルの一例を示す車両の上部１を示しており、車両用サンルーフパネル２は、車体３のルーフ部に設置される。このような車両用サンルーフパネル２に対して本発明が適用される。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an upper portion 1 of a vehicle showing an example of a sunroof panel to which the present invention is applied. The present invention is applied to such a vehicle sunroof panel 2.
　本発明の一実施態様に係る車両用サンルーフパネルを、図２、図３、図５に示す。図２は、本発明の一実施態様に係る車両用サンルーフパネル１０を上面側(車両外部側)から見るとともに車両幅方向における片側半分を実線で示した分解斜視図であり、サンルーフパネル１０は、樹脂製のパネル１１と、該パネル１１に固着されパネル１１の周縁に沿って車両幅方向Ｘ－Ｘに延びる部位１２ａと車両前後方向Ｙ－Ｙに延びる部位１２ｂとを有するＦＲＰ製のフレーム１２とからなる。ＦＲＰ製フレーム１２のＦＲＰは、強化繊維(好ましくは炭素繊維)と熱可塑性樹脂からなり、該強化繊維には短繊維が使用されて、ＦＲＰ製フレーム１２全体が射出成形されている。車両幅方向Ｘ－Ｘに延びる部位１２ａには、断面の形状によって該部位１２ａの車両幅方向Ｘ－Ｘにおける曲げ剛性を高める車両幅方向Ｘ－Ｘに延びる高剛性構造部１３が設けられており、本実施態様では高剛性構造部１３は、横断面形状がハット形の形状に形成されることにより、高い剛性が付与されている。 A vehicle sunroof panel according to an embodiment of the present invention is shown in FIGS. FIG. 2 is an exploded perspective view of the vehicle sunroof panel 10 according to an embodiment of the present invention viewed from the upper surface side (the vehicle exterior side) and one half in the vehicle width direction indicated by a solid line. An FRP frame 12 having a resin panel 11, a portion 12a that is fixed to the panel 11 and extends in the vehicle width direction XX along the periphery of the panel 11, and a portion 12b that extends in the vehicle front-rear direction YY; Consists of. The FRP of the FRP frame 12 is made of a reinforcing fiber (preferably carbon fiber) and a thermoplastic resin, and short fibers are used as the reinforcing fiber, and the entire FRP frame 12 is injection-molded. The portion 12a extending in the vehicle width direction XX is provided with a high-rigidity structure portion 13 extending in the vehicle width direction XX, which increases the bending rigidity of the portion 12a in the vehicle width direction XX depending on the shape of the cross section. In the present embodiment, the high-rigidity structure portion 13 is provided with high rigidity by forming the cross-sectional shape into a hat shape.
　高剛性構造部１３は、樹脂製のパネル１１に対して略平行に延びる底面部１３ａと、底面部１３ａの前方端から車両上方に立設された第１立設部１３ｂと、底面部１３ａの後方端から車両上方に立設されるとともに第１立設部１３ｂと対向する第２立設部１３ｃとにより構成されている。そのため、断面視にて底面部１３ａから第１立設部１３ｂ又は第２立設部１３ｃにかけて屈曲した屈曲部位となっている。このように、高剛性構造部１３は屈曲部位を有しており、屈曲部位を有していない場合に比べて高剛性となっている。また、底面部１３ａ、第１立設部１３ｂ及び第２立設部１３ｃを連結するリブ１３ｄが車両幅方向Ｘ－Ｘに並設されており、リブ１３ｄは高剛性構造部１３を補強している。このように、高剛性構造部１３は、底面部１３ａ、第１立設部１３ｂ、第２立設部１３ｃ及びリブ１３ｄを有する。 The high-rigidity structure portion 13 includes a bottom surface portion 13a that extends substantially parallel to the resin panel 11, a first standing portion 13b that is erected above the vehicle from the front end of the bottom surface portion 13a, and a bottom surface portion 13a. The second upright portion 13c is erected from the rear end above the vehicle and is opposed to the first upright portion 13b. Therefore, it is a bent portion bent from the bottom surface portion 13a to the first standing portion 13b or the second standing portion 13c in a cross-sectional view. Thus, the high-rigidity structure part 13 has a bending part, and is highly rigid compared with the case where it does not have a bending part. A rib 13d that connects the bottom surface portion 13a, the first standing portion 13b, and the second standing portion 13c is arranged in parallel in the vehicle width direction XX, and the rib 13d reinforces the high-rigidity structure portion 13. Yes. Thus, the highly rigid structure part 13 has the bottom face part 13a, the 1st standing part 13b, the 2nd standing part 13c, and the rib 13d.
　図３、図５は、図２に示した車両用サンルーフパネル１０のＦＲＰ製フレーム１２部分を下面側(車両内部側)から見た斜視図である。ＦＲＰ製フレーム１２の車両前後方向Ｙ－Ｙに延びる部位１２ｂには、該部位１２ｂの車両前後方向Ｙ－Ｙにおける曲げ剛性を高める車両前後方向Ｙ－Ｙに延びる補強部材としてのリブ１４が、該部位１２ｂと一体に設けられている（一体に成形されている）。本実施態様では、リブ１４は、実質的に同方向に延びる複数のリブ、とくに本実施態様では２本のリブ１４ａ、１４ｂから構成されており、リブ１４ａ、１４ｂのいずれかの一部が、上記高剛性構造部１３と一体に接続されるように成形されている。また、車両前後方向Ｙ－Ｙに延びる部位１２ｂには、車体３(図１に図示)側への取付部１５が設けられており、該取付部１５に上記リブ１４ａが接続されている。 3 and 5 are perspective views of the FRP frame 12 portion of the vehicle sunroof panel 10 shown in FIG. 2 as viewed from the lower surface side (vehicle interior side). In the portion 12b of the FRP frame 12 extending in the vehicle longitudinal direction YY, a rib 14 as a reinforcing member extending in the vehicle longitudinal direction YY is provided to increase the bending rigidity of the portion 12b in the vehicle longitudinal direction YY. It is provided integrally with the part 12b (molded integrally). In this embodiment, the rib 14 is composed of a plurality of ribs extending in substantially the same direction, in particular, in this embodiment, two ribs 14a and 14b, and a part of either of the ribs 14a and 14b is It is molded so as to be integrally connected to the high-rigidity structure portion 13. Further, a mounting portion 15 on the vehicle body 3 (shown in FIG. 1) side is provided at a portion 12b extending in the vehicle longitudinal direction YY, and the rib 14a is connected to the mounting portion 15.
　図４は、図３との比較のために示した従来の金属製のフレーム３１の車両幅方向における片側半分を例示している。車両幅方向に延びる部位３１ａには、断面の形状によって該部位３１ａの車両幅方向における曲げ剛性を高める車両幅方向に延びる高剛性構造部３２(例えば、上記同様の横断面形状がハット形の高剛性構造部)が設けられているが、車両前後方向に延びる部位３１ｂには、該部位３１ｂの車両前後方向における曲げ剛性を高めるための上記のような補強部材としてのリブは設けられていない。また、車体側への取付部３３は設けられているものの、金属製の板の一部を折り曲げて立ち上げた構造に構成されている。 FIG. 4 illustrates a half on one side in the vehicle width direction of a conventional metal frame 31 shown for comparison with FIG. The portion 31a extending in the vehicle width direction has a high-rigidity structure portion 32 extending in the vehicle width direction that increases the bending rigidity of the portion 31a in the vehicle width direction depending on the shape of the cross-section (for example, a cross-sectional shape similar to the above has a hat-shaped height). However, the portion 31b extending in the vehicle front-rear direction is not provided with a rib as a reinforcing member as described above for increasing the bending rigidity of the portion 31b in the vehicle front-rear direction. Moreover, although the attachment part 33 to the vehicle body side is provided, it is comprised by the structure which bent and started up a part of metal board.
　図２、図３、図５に示した本実施態様に係る車両用サンルーフパネル１０においては、フレーム部材がＦＲＰ製フレーム１２に構成され、とくにその車両前後方向Ｙ－Ｙに延びる部位１２ｂに一体に成形された補強部材としてのリブ１４が設けられることにより、車両前後方向Ｙ－Ｙにおける曲げ剛性が大幅に高められている。さらに、リブ１４の一部が、車両幅方向Ｘ－Ｘに延びる部位１２ａに設けられた高剛性構造部１３に接続されることにより、さらには車体３側への取付部１５に接続されることにより、車両前後方向Ｙ－Ｙにおける曲げ剛性が一層大幅に高められている。 In the vehicle sunroof panel 10 according to the present embodiment shown in FIGS. 2, 3 and 5, the frame member is configured as an FRP frame 12, and is integrated with a portion 12b extending in the vehicle longitudinal direction YY. By providing the molded rib 14 as the reinforcing member, the bending rigidity in the vehicle longitudinal direction YY is greatly enhanced. Further, a part of the rib 14 is connected to the high-rigidity structure portion 13 provided in the portion 12a extending in the vehicle width direction XX, and further connected to the mounting portion 15 on the vehicle body 3 side. As a result, the bending rigidity in the vehicle longitudinal direction YY is further greatly increased.
　本発明においては上記のように曲げ剛性が高められる結果、図６（上記実施態様）と図７(図４に示したような従来のフレームを用いた従来構造の車両用サンルーフパネル４１)に比較して示すように、サンルーフに生じる前述したような車両内部側から外部側に向かう方向Ｚ－Ｚに浮き上がるような変形の変形量が、小さく抑制されることになる(ただし、図６、図７では、分かりやすいように、変形量は誇張して示してある)。 In the present invention, as a result of increasing the bending rigidity as described above, it is compared with FIG. 6 (the above embodiment) and FIG. 7 (the conventional vehicle sunroof panel 41 using the conventional frame shown in FIG. 4). As shown, the amount of deformation of the sunroof that is lifted in the direction ZZ from the vehicle inner side toward the outer side as described above is suppressed to a small value (however, FIG. 6 and FIG. 7). (The deformation is exaggerated for the sake of clarity.)
　図６、図７に示すように、本発明におけるパネル変形量は、車両幅方向Ｘ－Ｘにおける上下方向Ｚ－Ｚの変形量に関しては従来構造とそれほど変わらないが、車両前後方向Ｙ－Ｙにおける上下方向Ｚ－Ｚの変形量に関しては、大幅に抑制される。 As shown in FIGS. 6 and 7, the panel deformation amount in the present invention is not much different from the conventional structure with respect to the deformation amount in the vertical direction ZZ in the vehicle width direction XX, but in the vehicle longitudinal direction YY. The amount of deformation in the vertical direction ZZ is greatly suppressed.
　本発明は、軽量化と高剛性化が要求されるあらゆる車両用サンルーフパネルに適用可能である。 The present invention can be applied to any vehicle sunroof panel that requires light weight and high rigidity.
