Description

本発明は、車両下部構造に関するものである。 The present invention relates to a vehicle lower structure.

近年、車両に対して、衝突時の安全性能に関する要求が増々高くなっている。例えば、前面衝突の対策として、車両前部のパワーユニットルームにクラッシャブルゾーンと呼ばれる部位を設け、このクラッシャブルゾーンを積極的に変形させることで後方の客室の変形を抑える技術が開発されている。 In recent years, there have been increasing demands on vehicles for safety performance in the event of a collision. For example, as a countermeasure against a frontal collision, a technology has been developed in which a part called a crushable zone is provided in the power unit room at the front of the vehicle, and the crushable zone is positively deformed to suppress deformation of the rear cabin.

上記のクラッシャブルゾーンの採用によって、特に寸法の小さな車両では、パワーユニットルーム内における部品の配置スペースが減りつつある。そのため、従来はパワーユニットルームに配置されていた部品であっても、現在では他の場所へ移動して配置される場合が増えてきている。 Due to the adoption of the crushable zone described above, the space for arranging parts in the power unit room is decreasing, especially in small-sized vehicles. Therefore, even if the parts were conventionally placed in the power unit room, they are now increasingly moved to other places and placed.

従来のパワーユニットルームに設けられていた部品の１つに、キャニスタがある。キャニスタは、燃料タンク等で発生する有害な燃料蒸発ガスを捕集する機器であって、主に円筒状や矩形状の容器に活性炭等の吸着材を内蔵した構造になっている。キャニスタは、燃料タンクおよびパワーユニットに配管で繋がれていて、燃料蒸発ガスをいったん吸着し、その燃料蒸発ガスをパワーユニットに引き込ませて燃料とともに燃焼させている。 One of the parts provided in the conventional power unit room is the canister. The canister is a device that collects harmful fuel evaporative gas generated in a fuel tank or the like, and has a structure in which an adsorbent such as activated carbon is mainly built in a cylindrical or rectangular container. The canister is connected to the fuel tank and the power unit by a pipe, and once adsorbs the fuel evaporative gas, the fuel evaporative gas is drawn into the power unit and burned together with the fuel.

キャニスタにおける燃料蒸発ガスの脱離性能は、キャニスタの温度が高いときのほうが向上する。そのため、車両によって、キャニスタの温度を維持する工夫が施されている。例えば、特許文献１では、シートの後方に設けられた二次電池に対し、その近傍であってフロアパネルの下側にキャニスタを配置して、キャニスタを二次電池の熱で温める技術が開示されている。 The desorption performance of the fuel evaporative gas in the canister is improved when the temperature of the canister is high. Therefore, some vehicles are devised to maintain the temperature of the canister. For example, Patent Document 1 discloses a technique of arranging a canister near the secondary battery provided behind the seat and below the floor panel to heat the canister with the heat of the secondary battery. ing.

特許第５０５６９５７号公報Japanese Patent No. 5056957

特許文献１のようにキャニスタをフロアパネルの下側に設置する構成であれば、キャニスタをパワーユニットルームから問題なく移動させることが可能である。しかしながら、特許文献１では、キャニスタは車両の後方にて燃料タンクと共に設置されていて、車両前方のパワーユニットから離れた位置となる。キャニスタがパワーユニットから離れると、キャニスタとパワーユニットを繋ぐ配管が長くなって圧力損失が大きくなるため、キャニスタの性能に影響が出るおそれがあり、例えばキャニスタを大型化するなどの対応が必要になる場合がある。 If the canister is installed under the floor panel as in Patent Document 1, the canister can be moved from the power unit room without any problem. However, in Patent Document 1, the canister is installed at the rear of the vehicle together with the fuel tank, and is located at a position away from the power unit at the front of the vehicle. If the canister is separated from the power unit, the piping connecting the canister and the power unit becomes long and the pressure loss increases, which may affect the performance of the canister. For example, it may be necessary to increase the size of the canister. be.

本発明は、このような課題に鑑み、キャニスタをパワーユニットルーム以外の場所に設置しつつその性能維持が可能な車両下部構造を提供することを目的としている。 In view of such problems, it is an object of the present invention to provide a vehicle lower structure capable of maintaining the performance of a canister while installing it in a place other than the power unit room.

上記課題を解決するために、本発明にかかる車両下部構造の代表的な構成は、車両のフロアパネルと、フロアパネルの前方に設置されるパワーユニットと、フロアパネルの下側に設置される燃料タンクと、フロアパネルのうち燃料タンクよりも前方の領域の上側に設置される二次電池と、二次電池の下方にフロアパネルを隔てて設置されて燃料タンクおよびパワーユニットに配管で繋がれるキャニスタとを備えることを特徴とする。 In order to solve the above problems, a typical configuration of the vehicle lower structure according to the present invention is a vehicle floor panel, a power unit installed in front of the floor panel, and a fuel tank installed under the floor panel. And the secondary battery installed on the upper side of the area in front of the fuel tank of the floor panel, and the canister installed below the secondary battery with the floor panel separated and connected to the fuel tank and the power unit by piping. It is characterized by being prepared.

It is characterized by including a secondary battery installed above the area in front of the secondary battery and a canister installed below the secondary battery with a floor panel separated and connected to a fuel tank and a power unit by a pipe.

上記構成によれば、二次電池の放射熱によってキャニスタを温めることができ、キャニスタの脱離性能を向上させることが可能になる。また、キャニスタを、従来のパワーユニットルームではなく、フロアパネルのうち燃料タンクより前方の領域、例えば客室の下方に配置することで、パワーユニットルーム内の空間に余裕を生じさせつつ、キャニスタをパワーユニットから遠ざけすぎないよう配慮している。この構成によって、キャニスタからパワーユニットへガスを引き込むときの圧力損失を抑え、キャニスタの性能維持を図ることができる。 According to the above configuration, the canister can be heated by the radiant heat of the secondary battery, and the desorption performance of the canister can be improved. In addition, by arranging the canister in the area of the floor panel in front of the fuel tank, for example, below the cabin, instead of the conventional power unit room, the canister is kept away from the power unit while creating a space in the power unit room. I am careful not to go too far. With this configuration, it is possible to suppress the pressure loss when drawing gas from the canister to the power unit and maintain the performance of the canister.

上記のフロアパネルは、車幅方向中央に形成され上方へ膨出し前後方向に延びているセンタートンネルを有し、当該車両下部構造はさらに、センタートンネルを通る排気管を備え、キャニスタは、フロアパネルの側縁よりもセンタートンネル寄りに設置されてもよい。 The above floor panel has a center tunnel formed in the center in the vehicle width direction and bulging upward and extending in the front-rear direction, the vehicle lower structure further includes an exhaust pipe passing through the center tunnel, and the canister is a floor panel. It may be installed closer to the center tunnel than the side edge of the.

上記構成によれば、排気管の放射熱も利用してキャニスタを温めることができ、キャニスタの脱離性能をさらに向上させることが可能になる。 According to the above configuration, the canister can be heated by utilizing the radiant heat of the exhaust pipe, and the desorption performance of the canister can be further improved.

上記の排気管は、前後方向の途中箇所に消音室を有していて、キャニスタは、消音室の側方に設置されてもよい。 The above exhaust pipe has a muffling chamber in the middle of the front-rear direction, and the canister may be installed on the side of the muffling chamber.

上記構成によれば、排気管のうち特に消音室からの放射熱を利用して、キャニスタを効率よく温めることが可能になる。 According to the above configuration, the canister can be efficiently heated by utilizing the radiant heat from the exhaust pipe, especially from the anechoic chamber.

当該車両下部構造はさらに、キャニスタの下方にてフロアパネルを覆うアンダカバーを備えてもよい。 The vehicle undercarriage may further include an undercover that covers the floor panel below the canister.

上記のアンダカバーを備えることで、キャニスタを走行風から保護し、キャニスタの温度低下、ひいては脱離性能の低下を防ぐことが可能になる。また、走行中のキャニスタへの飛び石の衝突（チッピング）を防ぐことも可能になる。 By providing the above-mentioned undercover, it is possible to protect the canister from the running wind and prevent the temperature of the canister from decreasing and the desorption performance from decreasing. In addition, it is possible to prevent a stepping stone from colliding with a running canister (chipping).

上記のキャニスタは、フロアパネルの下側のうち燃料タンクよりもパワーユニット寄りに設置されてもよい。 The canister may be installed closer to the power unit than the fuel tank under the floor panel.

上記構成によれば、キャニスタからパワーユニットへガスを引き込むときの圧力損失をより低減し、キャニスタの性能維持を図ることが可能になる。 According to the above configuration, it is possible to further reduce the pressure loss when drawing gas from the canister to the power unit and maintain the performance of the canister.

図１は、本発明の実施例にかかる車両下部構造１００の概要を示す図である。以下、図１その他の本願のすべての図面において、車両前後方向をそれぞれ矢印F(Forward)、B(Backward)、車幅方向の左右をそれぞれ矢印L(Leftward)、R(Rightward)、車両上下方向をそれぞれ矢印U(Upward)、D(Downward)で例示する。 FIG. 1 is a diagram showing an outline of a vehicle lower structure 100 according to an embodiment of the present invention. Hereinafter, in FIG. 1 and all other drawings of the present application, the front-rear direction of the vehicle is indicated by arrows F (Forward) and B (Backward), and the left and right directions of the vehicle width are indicated by arrows L (Leftward) and R (Rightward), respectively. Are illustrated by arrows U (Upward) and D (Downward), respectively.

車両下部構造１００は、車両の床を構成するフロアパネルとして、客室を形成する領域にメインフロアパネル１０２ａを備え、その後方の客室の後側から荷室にかけての範囲を形成する領域にリアフロアパネル１０２ｂを備えている。パワーユニット１０４は、エンジンや電気モータなどの動力を発生させる装置であって、メインフロアパネル１０２ａの前方に設置されている。パワーユニット１０４で使用する燃料は、リアフロアパネル１０２ｂの下側に設置された燃料タンク１０６に貯留されている。また、メインフロアパネル１０２ａの下方は、空気の整流および小石等からの保護を行うアンダカバー１０８で覆われている。 The vehicle lower structure 100 includes a main floor panel 102a in an area forming a passenger compartment as a floor panel constituting the floor of the vehicle, and a rear floor panel 102b in an area forming a range from the rear side of the passenger compartment to the luggage compartment behind the main floor panel 102a. It is equipped with. The power unit 104 is a device for generating power such as an engine and an electric motor, and is installed in front of the main floor panel 102a. The fuel used in the power unit 104 is stored in the fuel tank 106 installed under the rear floor panel 102b. Further, the lower part of the main floor panel 102a is covered with an undercover 108 that rectifies air and protects it from pebbles and the like.

図２は、図１の車両下部構造１００の概略的なＡ－Ａ断面図である。図２に示すように、メインフロアパネル１０２ａの上側には二次電池１１０が設置されている。二次電池１１０は、例えば電装品に電気を供給する蓄電池として実施される。 FIG. 2 is a schematic cross-sectional view taken along the line AA of the vehicle lower structure 100 of FIG. As shown in FIG. 2, a secondary battery 110 is installed on the upper side of the main floor panel 102a. The secondary battery 110 is implemented as, for example, a storage battery that supplies electricity to electrical components.

キャニスタ１１２は、燃料タンク１０６等で発生する燃料蒸発ガスを、大気中に放出しないよう吸着し、パワーユニット１０４に引き込ませる機器である。キャニスタ１１２は、容器の内部に活性炭等の吸着材を充填させた構造になっていて、配管（図示省略）で燃料タンク１０６およびパワーユニット１０４と繋がれる。 The canister 112 is a device that adsorbs the fuel evaporative gas generated in the fuel tank 106 or the like so as not to be released into the atmosphere and draws it into the power unit 104. The canister 112 has a structure in which the inside of the container is filled with an adsorbent such as activated carbon, and is connected to the fuel tank 106 and the power unit 104 by a pipe (not shown).

当該車両下部構造１００では、キャニスタ１１２を、二次電池１１０の下方にメインフロアパネル１０２ａを隔てて設置している。キャニスタ１１２の吸着材からの燃料蒸発ガスの脱離性能は、温度が影響する。本実施例の構成によれば、キャニスタ１１２が、二次電池１１０に対してメインフロアパネル１０２ａを隔てて隣接して設けられているため、二次電池１１０からの放射熱によってキャニスタ１１２を温めることができ、キャニスタ１１２の脱離性能を向上させることが可能になる。 In the vehicle lower structure 100, the canister 112 is installed below the secondary battery 110 with the main floor panel 102a interposed therebetween. The desorption performance of the fuel evaporative gas from the adsorbent of the canister 112 is affected by the temperature. According to the configuration of this embodiment, since the canister 112 is provided adjacent to the secondary battery 110 with the main floor panel 102a interposed therebetween, the canister 112 is heated by the radiant heat from the secondary battery 110. This makes it possible to improve the desorption performance of the canister 112.

本実施例では、キャニスタ１１２を、従来のパワーユニットルームではなく、客室の下方に配置することで、パワーユニットルーム内の空間に余裕を生じさせつつ、キャニスタ１１２をパワーユニット１０４から遠ざけすぎないよう配慮している。これによって、キャニスタ１１２からパワーユニット１０４にガスを引き込むときの圧力損失を抑え、キャニスタ１１２の性能維持を図ることが可能になっている。また、本実施例であれば、パワーユニットルーム等の車両のレイアウトの自由度を向上させることができ、例えばクラッシャブルゾーンの拡大を図ることも可能になる。 In this embodiment, by arranging the canister 112 below the guest room instead of the conventional power unit room, the canister 112 is not moved too far from the power unit 104 while creating a space in the power unit room. There is. This makes it possible to suppress the pressure loss when drawing gas from the canister 112 to the power unit 104 and maintain the performance of the canister 112. Further, in the present embodiment, the degree of freedom in the layout of the vehicle such as the power unit room can be improved, and for example, the crushable zone can be expanded.

上述したように、メインフロアパネル１０２ａの下方にはアンダカバー１０８が設けられていて、キャニスタ１１２は下方をアンダカバー１０８によって覆われている。この構成であれば、アンダカバー１０８によってキャニスタ１１２を走行風から保護し、キャニスタ１１２の温度低下、ひいては脱離性能の低下を防ぐことができる。また、アンダカバー１０８を利用することによって、専用のカバー等を設けずとも、走行中のキャニスタ１１２への飛び石の衝突（チッピング）を防ぐことができる。 As described above, the undercover 108 is provided below the main floor panel 102a, and the canister 112 is covered with the undercover 108 below. With this configuration, the canister 112 can be protected from the running wind by the undercover 108, and the temperature of the canister 112 can be prevented from being lowered, and the desorption performance can be prevented from being lowered. Further, by using the under cover 108, it is possible to prevent a stepping stone from colliding with the canister 112 during traveling (chipping) without providing a dedicated cover or the like.

図３は、図１の車両下部構造１００からアンダカバー１０８を省略した図である。メインフロアパネル１０２ａの車幅方向中央には、センタートンネル１１４が設けられている。センタートンネル１１４は、上方へ膨出したトンネル状の部位であり、車両の前後方向に延びて形成されている。センタートンネル１１４の内側には、パワーユニット１０４から延びる排気管１１６が通っている。排気管１１６は、前後方向の途中箇所に、ガスを排出する際の音を低減する消音室１１８を有している。 FIG. 3 is a diagram in which the undercover 108 is omitted from the vehicle lower structure 100 of FIG. A center tunnel 114 is provided at the center of the main floor panel 102a in the vehicle width direction. The center tunnel 114 is a tunnel-shaped portion that bulges upward, and is formed so as to extend in the front-rear direction of the vehicle. An exhaust pipe 116 extending from the power unit 104 passes through the inside of the center tunnel 114. The exhaust pipe 116 has a muffling chamber 118 in the middle of the front-rear direction to reduce noise when exhausting gas.

本実施例では、キャニスタ１１２は、車幅方向において、メインフロアパネル１０２ａの側縁のサイドシル１２０よりもセンタートンネル１１４寄りに設置されている。特にキャニスタ１１２は、消音室１１８の側方に位置するよう設置されている。この構成によれば、排気管１１６の放射熱、特に消音室１１８からの放射熱を利用してキャニスタ１１２を効率よく温めることができ、キャニスタ１１２の脱離性能をさらに向上させることができる。また、キャニスタ１１２を車幅方向中央寄りに配置することで、側面衝突等の衝撃からキャニスタ１１２を保護することが可能になる。 In this embodiment, the canister 112 is installed closer to the center tunnel 114 than the side sill 120 on the side edge of the main floor panel 102a in the vehicle width direction. In particular, the canister 112 is installed so as to be located on the side of the muffling chamber 118. According to this configuration, the canister 112 can be efficiently heated by utilizing the radiant heat of the exhaust pipe 116, particularly the radiant heat from the muffling chamber 118, and the desorption performance of the canister 112 can be further improved. Further, by arranging the canister 112 closer to the center in the vehicle width direction, it becomes possible to protect the canister 112 from an impact such as a side collision.

また、キャニスタ１１２は、車両前後方向において、後方の燃料タンク１０６よりも、前方のパワーユニット１０４寄りに設置されている。キャニスタ１１２をパワーユニット１０４寄りに配置することで、キャニスタ１１２からパワーユニット１０４へガスを引き込むときの圧力損失を低減し、キャニスタ１１２の性能維持を図ることが可能になる。 Further, the canister 112 is installed closer to the power unit 104 in front of the fuel tank 106 in the rear in the front-rear direction of the vehicle. By arranging the canister 112 closer to the power unit 104, it is possible to reduce the pressure loss when drawing gas from the canister 112 to the power unit 104 and maintain the performance of the canister 112.
