Definitions
- the present invention relates to a vehicle lower structure in which a floor member, a fuel tank, and an exhaust pipe are arranged in a lower portion of the vehicle.
- Patent Document 1 Japanese Patent Laid-Open No. 2007-276614 discloses that a substantially U-shaped recess extending in the vehicle front-rear direction is formed in the center of the lower surface of the fuel tank, and the exhaust pipe is located in the recess. The arranged structure is described.
- the lower part is a liquid layer and the upper part is a gas layer with the liquid level of the fuel as a boundary.
- the amount of fuel that can be stored in the fuel tank is reduced accordingly.
- the enlargement of a fuel tank is caused.
- an object of the present invention is to obtain a vehicle lower structure capable of securing a capacity while suppressing an increase in the size of a fuel tank.
- a floor member constituting a floor portion of the vehicle, a fuel tank disposed below the vehicle with respect to the floor member, and extending in the vehicle front-rear direction, and partially with the fuel tank in a plan view of the vehicle
- An overlapping portion is provided, and an exhaust pipe disposed between the fuel tank and the floor member is provided at the overlapping portion.
- the exhaust pipe extending in the vehicle front-rear direction includes an overlapping portion that partially overlaps the fuel tank in a plan view of the vehicle.
- the exhaust pipe is disposed between the fuel tank and the floor member. Since it is not necessary to form a recess or the like for disposing the exhaust pipe on the lower surface of the fuel tank, the volume of the liquid layer in the lower portion of the fuel tank, that is, in the fuel tank does not decrease. Therefore, it is possible to secure a necessary capacity while suppressing an increase in the size of the fuel tank.
- At least a portion of the upper surface of the fuel tank immediately below the overlapping portion may be positioned above the liquid level in the fuel tank.
- an air layer in the fuel tank exists between the liquid layer in the fuel tank and the overlapping portion of the exhaust pipe, and the heat of the exhaust pipe is transferred to the liquid layer (fuel) in the fuel tank by this gas layer. It becomes difficult to be transmitted.
- the “liquid level” in the fuel tank in this configuration is the “full tank level” set in the fuel tank, it is possible to ensure that the air layer in the fuel tank immediately below the overlapped portion exists. it can.
- a recess that accommodates at least a part of the overlapping portion of the exhaust pipe may be formed on at least the upper surface of the fuel tank.
- Space efficiency can be increased by accommodating at least a part of the overlapping portion of the exhaust pipe in the recess.
- the concave portion is formed on the upper surface of the fuel tank, and does not reduce the volume of the liquid layer in the fuel tank. Therefore, there is no influence or little influence on securing the capacity of the fuel tank.
- the lower surface of the fuel tank may be flat.
- the aerodynamic characteristic of the vehicle can be improved without using a member such as an undercover.
- the exhaust pipe may be disposed below the overlapping portion on the vehicle front side of the overlapping portion. Thereby, the space efficiency in the front side rather than an overlap part can be made high.
- the recess may be formed continuously from the upper surface to the front surface of the fuel tank. Since the exhaust pipe can be partially accommodated in the recess also on the front surface of the fuel tank, the space efficiency can be further increased.
- the exhaust pipe may be arranged in non-contact with the fuel tank. Thereby, transmission of heat from the exhaust pipe to the fuel tank can be suppressed, and generation of evaporated fuel in the fuel tank can be suppressed.
- the present invention is configured as described above, it is possible to secure a capacity while suppressing an increase in the size of the fuel tank.
- FIG. 1 is a plan view schematically showing a lower part of a vehicle to which a vehicle lower part structure of a first embodiment of the present invention is applied.

- the front floor 18 is provided at a position lower than the center floor 20, and the front floor 18 and the center floor 20 are continuous by the step portion 24.
- a seat 26 having a seat cushion 28 and a seat back 30 is attached to the center floor 20.
- a fuel tank 32 is attached behind the front floor 18 and below the center floor 20. Fuel supplied to the engine (not shown) of the vehicle 14 is accommodated in the fuel tank 32.
- the upper surface 32U of the fuel tank 32 is formed with a recess 34 in which a plate material constituting the fuel tank is recessed downward at a position substantially in the center in the vehicle width direction. That is, the fuel tank 32 is locally thin due to the recess 34.
- the upper surface 32U of the fuel tank 32 is disposed at a position closer to the center floor 20 on both sides in the vehicle width direction than the recess 34.
- a recess 48 is also formed on the front surface 32F of the fuel tank 32, and the recess 34 and the recess 48 are continuous.
- such a recess is not formed in the lower surface 32L of the fuel tank 32, and is flat.
- the term “flat” refers to a flatness that does not affect the amount of fuel that can be stored in the fuel tank 32 (the volume of the liquid layer LP portion). Beads, ribs, and the like for reinforcing 32L may be formed.
- the position of the fuel tank 32 is adjusted so that the lower surface 32L of the fuel tank 32 is substantially flush with the front floor 18 (substantially the same height in the vertical direction), and is attached to the vehicle body. It has been.
- the lower surface 40L of the muffler 40 and the rear floor 22 are also at the same height, and the entire vehicle body from the front floor 18 to the lower surface of the fuel tank 32 and the lower surface of the muffler 40 to the rear floor 22 is substantially flattened. ing.
- An exhaust pipe 36 is extended from an engine (not shown). As shown in FIGS. 1 and 2, the exhaust pipe 36 extends in the vehicle front-rear direction. When the exhaust pipe 36 is traced from the front side of the vehicle, the exhaust pipe 36 passes under the front floor 18 at the approximate center in the vehicle width direction. From the position past the front floor 18, the exhaust pipe 36 is raised obliquely upward toward the rear of the vehicle.
- the exhaust pipe 36 extends to the rear of the vehicle and partially overlaps the fuel tank 32 when the vehicle 14 is viewed in plan (see FIG. 1).
- the exhaust pipe 36 is located between the fuel tank 32 and the floor member 16 (center floor 20) in the overlapping portion 36P.
- the exhaust pipe 36 is accommodated in the recess 34 of the fuel tank 32 in the overlapping portion 36P. In this way, the exhaust pipe 36 maintains a state where it is located between the fuel tank 32 and the floor member 16 (center floor 20). When viewed in a cross section in the vehicle width direction, a part (or all) of the overlapping portion 36P is accommodated in the recess 34 and extends toward the rear of the vehicle.
- the exhaust pipe 36 is partially accommodated in the recess 48 on the front side of the fuel tank 32.
- the exhaust pipe 36 is further disposed at a position relatively lower than the overlapping portion 36P on the front side thereof.
- the space efficiency of the vehicle 14 is increased by disposing the exhaust pipe 36 below the front side of the overlapping portion 36P.
- the front floor 18 can be positioned below the center floor 20.
- the exhaust pipe 36 is supported by the vehicle body by a support member (not shown) so that a gap is formed between the exhaust pipe 36 and the fuel tank 32. . That is, the exhaust pipe 36 and the fuel tank 32 are not in contact with each other. Air is present between the exhaust pipe 36 and the fuel tank 32, and heat transfer from the exhaust pipe 36 to the fuel tank 32 is suppressed.
- the structure shown in FIG. 3B may be particularly used. In this structure, the upper surface 32U is shaped such that the recess 34 is positioned above the liquid level LS set in the fuel tank 32, and immediately below the overlapping portion 36P of the exhaust pipe 36.
- a gas layer GP (heat insulation layer) in the fuel tank 32 exists.
- the liquid level LS in this case is, for example, a full tank liquid level set by a full tank regulating valve (not shown) in the fuel tank 32 (a position lower than the upper surface of the fuel tank 32 by a predetermined amount).
- the concave portion 34 is formed in the shape of the upper surface 32U so as to be positioned above the full liquid level, the liquid layer in the exhaust pipe 36 and the fuel tank 32 immediately below the overlapping part 36P of the exhaust pipe 36. A state in which the gas phase GP exists between the LP and the LP can be more reliably realized.
- the center floor 20 is also provided with a recess 50 that is recessed upward at a substantially central portion in the vehicle width direction.
- the exhaust pipe 36 is partially accommodated in the recess 50 or is disposed at a position where a gap is generated between the exhaust pipe 36 and the center floor 20. For this reason, transmission of heat from the exhaust pipe 36 to the center floor 20 is suppressed.
- a muffler 40 is disposed on the vehicle rear side of the fuel tank 32. Further, rear suspensions 44 (only a part of which is shown in FIG. 2) are provided at positions on both sides of the muffler 40 in the vehicle width direction.
- the muffler 40 is placed horizontally so that the longitudinal direction thereof coincides with the vehicle width direction, and the exhaust pipe 36 is connected to the muffler 40 at the approximate center in the vehicle width direction.
- the exhaust pipe 36 is connected to the muffler 40, and an exhaust pipe 46 (see FIG. 1) extends from the muffler 40 toward the rear of the vehicle.
- FIG. 5 shows a vehicle lower structure 112 in which the exhaust pipe 136 is disposed below the fuel tank 132 as a comparative example.
- the exhaust pipe 136 does not protrude below the lower surface 132L of the fuel tank 132, or a recess 134 is formed on the lower surface 132L in order to reduce the protruding amount.
- the fuel tank 132 having the structure in which the concave portion 134 is formed on the lower surface 132L as described above, the amount of fuel that can be accommodated inside is reduced. That is, in the fuel tank 132, since the lower layer is the liquid layer LP and the upper layer is the gas layer GP with the liquid level LS as a boundary, the concave portion 134 has entered the portion of the liquid layer LP. Accordingly, in order to secure the amount of fuel that can be accommodated in the fuel tank 132, the fuel tank 132 needs to be enlarged in the vehicle front-rear direction, the vehicle width direction, or the vertical direction, so the fuel tank 132 becomes large.
- a concave portion for accommodating the exhaust pipe 136 is formed on the side surface of the fuel tank 132 is considered, but even in this case, a part of the concave portion greatly extends to the liquid layer LP in the fuel tank. The amount of fuel that can be stored in the fuel tank 132 is reduced.
- a recess 34 is provided on the upper surface 32U of the fuel tank 32, and a part of the exhaust pipe 36 is accommodated in the recess 34.
- the fuel tank 32 is disposed so as to be close to the center floor 20 at both side portions of the recess 34 in the vehicle width direction. In other words, the gap between the fuel tank 32 and the center floor 20 is reduced, and the fuel tank 32 is also present in this gap portion. For this reason, the fuel tank 32 can be further downsized (the amount of fuel that can be accommodated is ensured), and space efficiency in the case where other members are arranged around the fuel tank 32 is increased.
- the recess 34 is formed not only on the upper surface 32U of the fuel tank 32 but also on the front surface 32F, and the exhaust pipe 36 is partially accommodated in the recess 34 of the front surface 32F.
- the exhaust pipe 36 is located on the vehicle rear side in this portion as much as it enters the recess 34. For this reason, the space efficiency in the vehicle front side of the fuel tank 32 becomes high.
- the lower surface 32L of the fuel tank 32 is flat and has the same height as the front floor 18.
- the entire vehicle body from the front floor 18 to the rear floor 22 through the lower surface 32L of the fuel tank 32 and the lower surface of the muffler 40 is substantially flattened, that is, has substantially the same height.
- a gap is formed between the exhaust pipe 36 and the fuel tank 32 so as to be non-contacting, and direct heat transfer from the exhaust pipe 36 to the fuel tank 32 is suppressed. Also by this, it is possible to suppress the temperature rise of the fuel in the fuel tank 32 and the generation of evaporative fuel accompanying this temperature rise.

Abstract
Description
本発明において、たとえば、前記燃料タンクの少なくとも上面に、前記排気管の前記重なり部の少なくとも一部を収容する凹部が形成されていてもよい。この凹部に排気管の重なり部の少なくとも一部を収容することで、スペース効率を高くすることができる。なお、凹部は燃料タンクの上面に形成されており、燃料タンク内において液層の部分の容積を小さくしないので、燃料タンクの容量を確保する点では影響がないか、若しくは影響が少ない。
本実施形態において、特に、図3Bに示す構造としてもよい。この構造では、燃料タンク32内において設定されている液面LSに対し、これよりも上方に凹部34が位置するような上面32Uの形状とされており、排気管36の重なり部36Pの直下において、燃料タンク32内の気層GP(断熱層)が存在している。このように、燃料タンク32内の気層GPが重なり部36Pの直下に存在することで、排気管36から燃料への熱の伝わりがさらに抑制されている。なお、この場合の液面LSとしては、たとえば、燃料タンク32内において満タン規制バルブ(図示省略)等により設定される満タン液面(燃料タンク32の上面よりも所定量低い位置とされる)を考慮し、凹部34を満タン液面よりも上方に位置させるような上面32Uの形状とすれば、排気管36の重なり部36Pの直下において、排気管36と燃料タンク32内の液層LPとの間に気層GPが存在している状態をより確実に実現できる。
また、図13に示すように、フロア部材16に凹部50が形成されていない構成でもよい。燃料タンク32に形成する凹部34の位置としても、排気管36との位置関係で決められるものであり、たとえば図14に示すように、燃料タンク32における車幅方向端部に凹部34が形成されていてもよい。
図13及び図14のいずれの構造においても、図3Bに示した構造と同様に、排気管36の重なり部36Pの直下において、排気管36と燃料タンク32内の液層(満タン液位時)との間に、気層が存在するような凹部34(上面32U)の形状とすることが可能である。
