As shown in FIG. 2, the rear floor pan 12 is formed with a storage recess 12A, and a spare tire 14 and a jack (not shown) can be stored in the storage recess 12A. A rear bumper 16 is disposed on the vehicle rear side of the housing recess 12A, and the rear bumper 16 includes a rear bumper cover 16A disposed along the vehicle width direction at the rear end of the vehicle.

  A rear floor side member 18 whose longitudinal direction is substantially the longitudinal direction of the vehicle body is attached to the lower side of both sides of the rear floor pan 12 shown in FIG. 1 by welding or the like (in FIG. 1, the rear floor pan 12 is seen through). The rear floor side member 18 is shown in FIG. As shown in FIG. 3 (B), the rear floor side member 18 is formed in a cross-sectional hat shape with the vehicle upper direction side opened, and the left and right flange portions 18A are joined to the rear floor pan 12 to be closed. A cross section 20 is formed. Thus, the rear floor side member 18 reinforces the rear floor pan 12 and increases the body rigidity. Here, as shown in FIG. 4, the rear floor side member 18 is a component that receives a load directly via the rear bumper 16 at the time of rear collision (collision), and the input load from the rear bumper 16 is a predetermined value or more. Then, it is deformed and absorbs energy. In addition, the virtual line (two-dot chain line) in FIG. 4 has shown the deformation | transformation mode at the time of rear collision.

  As shown in FIGS. 1 and 2, a rear floor cross member 24 and a jack-up point member 26 are attached to the lower side of the rear floor pan 12 between the rear wheels 22 by welding or the like (in FIG. 1, The rear floor cross member 24 is shown with the rear floor pan 12 seen through). The rear floor cross member 24 and the jack-up point member 26 are not parts that receive a load directly at the time of a rear collision (at the time of a collision). As shown in FIG. 2, a fuel tank 32, an ORVR canister 34, an intermediate beam 36, and the like are disposed in the vicinity of the rear floor cross member 24.

  As shown in FIG. 1, the rear floor cross member 24 is arranged with the vehicle width direction as a longitudinal direction, and both ends of the rear floor cross member 24 are joined to the rear floor side member 18. As shown in FIG. 3A, the rear floor cross member 24 has a cross-sectional hat shape in which the vehicle upper direction side is opened, and the front end portion and the rear end flange portion 24A are joined to the rear floor pan 12. Yes. That is, a space 38 is formed by the rear floor pan 12 and the rear floor cross member 24. Thus, the rear floor cross member 24 reinforces the rear floor pan 12 and increases the body rigidity.

  The jack-up point member 26 is a high-strength member, and is disposed substantially below the rear floor cross member 24. In this embodiment, the jack-up point member 26 includes a garage jack bracket 28 and a garage jack reinforcement 30. The garage jack bracket 28 has a substantially container shape with the upper side opened, and the open end portion side is attached to the rear floor cross member 24 and the garage jack reinforcement 30 by welding or the like so that a garage jack (not shown) is applied. Yes. The garage jack reinforcement 30 has a substantially container shape with the upper side and one side opened, and the open end is attached to the rear floor pan 12 and the rear floor cross member 24 by welding or the like, and is integrated with the garage jack bracket 28. It has become.

  Here, a space 40 is formed by the rear floor pan 12, the garage jack reinforcement 30, and the rear floor cross member 24, and a space 42 is formed by the garage jack bracket 28, the garage jack reinforcement 30, and the rear floor cross member 24. Is separated from the exterior space 44 by a garage jack bracket 28. In the present embodiment, the space 40 is formed by three members of the rear floor pan 12, the garage jack reinforcement 30 and the rear floor cross member 24. However, the space 40 is formed by two members of the rear floor pan 12 and the garage jack reinforcement 30. (The open end (outer peripheral part) of the garage jack reinforcement 30 may be joined only to the rear floor pan 12 to form the space 40). Further, in this embodiment, the space 42 is formed by three members of the garage jack bracket 28, the garage jack reinforcement 30, and the rear floor cross member 24, but the space 42 is formed by the garage jack bracket 28 and the garage jack reinforcement 30. A space 42 may be formed as a structure in which the front end portion of the garage jack reinforcement 30 joined to the rear floor cross member 24 extends to the front side of the vehicle and joined to the garage jack bracket 28 in FIG. 3A. May be formed). In addition, as FIG. 1 shows, the joining range with the rear floor pan 12 in the member 26 for jackup points is a narrow range.

  A large-capacity battery 46 in which a large number of batteries (for example, a lithium battery, a nickel hydride storage battery, a nickel cadmium storage battery, etc.) are connected in series is mounted on the rear floor pan 12 in the vehicle compartment between the rear wheels 22. Since the battery 46 is a heavy part, steering stability can be improved by disposing it at a position close to the center of gravity of the vehicle (position close to the center). When the battery 46 enters a predetermined state (for example, an overcharge state or an overdischarge state), the battery 46 discharges a gas such as hydrogen. For this reason, the power supply device having the battery 46 is provided with a device for discharging these gases.

  An exhaust hose 48 is connected to the battery 46 as an exhaust pipe through which gas (exhaust gas) from the battery flows. As shown in FIG. 3, the front end portion 48 </ b> A of the exhaust hose 48 passes through the rear floor pan 12 and is inside the rear floor cross member 24 (in the space 38), in other words, in the passenger compartment 60 and the outer space 44. It is arranged in the middle space (a place that becomes a middle point). In the present embodiment, the distal end portion 48 </ b> A of the exhaust hose 48 is located above the garage jack bracket 28 in the jackup point member 26.

  A discharge hole 24 </ b> B is formed through the bottom 24 </ b> Z constituting the lower portion of the rear floor cross member 24 at a position substantially opposite to the tip 48 </ b> A of the piped exhaust hose 48. The garage jack bracket 28 is formed with a plurality of discharge holes 28 </ b> A communicating with the space 42 and the outside space 44, and the garage jack reinforcement 30 is also formed with a plurality of discharge holes 30 </ b> A. Yes.

  As a result, the rear floor pan 12, the rear floor cross member 24, and the jack-up point member 26 form an exhaust passage 50, and the exhaust hose 48 communicates with the outside space 44 to exhaust the exhaust from the exhaust hose 48 to the outside of the vehicle. Released. That is, the rear floor pan 12, the rear floor cross member 24, and the jack-up point member 26 form a gas tank structure in which the exhaust from the exhaust hose 48 is temporarily retained, and the exhaust from the exhaust hose 48 is transferred to the rear floor pan 12. And a space 38 formed by the rear floor cross member 24 and the spaces 42 and 40 separated from the vehicle exterior space 44 by the jack-up point member 26, and then discharged to the outside of the vehicle (FIG. 3 (A) arrow A and arrow B indicate the flow direction of the exhaust gas). The exhaust passage 50 can be regarded as an exhaust duct, and also functions as a mudguard for preventing mud from being applied to the exhaust hose 48.

  In FIG. 3A, the exhaust hole is not shown in the portion where the garage jack reinforcement 30 separates the space 40 and the outside space 44, but the garage jack reinforcement 30 separates the space 40 and the outside space 44 from each other. A discharge hole may be formed through the formed portion. Further, in the present embodiment, the discharge hole 30 </ b> A is formed through the garage jack reinforcement 30, but the discharge hole 30 </ b> A may not be formed in the garage jack reinforcement 30.

(Action / Effect)
Next, the operation and effect of the above embodiment will be described.

  As shown in FIG. 3, since the exhaust passage 50 communicates the exhaust hose 48 and the outside space 44, the exhaust from the battery 46 (battery) mounted in the passenger compartment 60 is exhausted from the exhaust hose. 48 is discharged from the vehicle through the exhaust passage 50. By interposing the exhaust passage 50, it is possible to prevent the exhaust hose 48 from being blocked by mud or the like outside the vehicle.

  Further, the exhaust air from the exhaust hose 48 passes through the space 38 formed by the rear floor pan 12 and the rear floor cross member 24, and the spaces 42 and 40 separated from the vehicle exterior space 44 by the jack-up point member 26. After that, since the exhaust gas is discharged to the outside of the vehicle, the exhaust gas is diluted in the space 38 formed by the rear floor pan 12 and the rear floor cross member 24 and then separated from the vehicle outer space 44 by the jack-up point member 26. , 40 and discharged outside the vehicle in a more diluted state.

  Here, since the exhaust passage 50 is formed by the rear floor pan 12, the rear floor cross member 24, and the jack-up point member 26, for example, the rear floor pan 12 and the rear floor side member 18 connected to the rear floor pan 12 at a long distance. Compared to the case where the exhaust passage is formed, the joining range with the rear floor pan 12 (the range sealed by the sealer, etc.) is narrower, and the mounting hole to the rear floor pan 12 (the portion where bolts are fastened, etc.) Such holes (portions sealed by plug holes, etc.) are significantly reduced, and leakage (back flow) into the vehicle compartment 60 due to poor sealing performance can be reliably suppressed. Incidentally, with respect to the jack-up point member 26, it is possible to make the position of the hole that needs to be sealed zero.

  As shown in FIG. 4, at the time of a rear collision, the collision load F is input to the rear bumper 16 and transmitted to the rear floor side member 18 disposed on the front side of the vehicle. At this time, as indicated by a virtual line (two-dot chain line) in FIG. 4, the rear floor side member 18 is deformed so that the rear end side is lifted while being compressed in the axial direction. Due to the deformation of the rear floor side member 18, energy at the time of collision is absorbed. Here, the rear floor cross member 24 and the jack-up point member 26 are not structural members such as the rear floor side member 18 that directly receive a load and absorb energy at the time of rear collision, so that at the time of rear collision (at the time of collision). However, the amount of deformation is minimized. Therefore, the exhaust passage 50 can be prevented from being blocked, and the exhaust hose 48 can be effectively prevented from being compressed in the closing direction by the rear floor cross member 24 and the jack-up point member 26.

  Furthermore, since the rear floor cross member 24 and the jack-up point member 26 are not members that receive a load directly at the time of rear-end collision, there is very little possibility that the seal portion between the rear floor pan 12 will break.

  As described above, according to the present embodiment, the gas from the battery 46 (see FIG. 3) can be properly discharged to the outside of the passenger compartment not only during normal times but also during a collision with a simple configuration.

Further, the second embodiment except for the points described below, because it is almost the same configuration as the first preferred embodiments, substantially the same components, omitted with the same reference numerals To do.

  As shown in FIG. 5, the distal end portion 48 </ b> A of the exhaust hose 48 is disposed in a space 40 formed by the rear floor pan 12, the garage jack reinforcement 30, and the rear floor cross member 24 while penetrating the rear floor pan 12. ing. Further, the rear floor cross member 24 is not formed with the discharge hole 24B (see FIG. 3) in the first embodiment.

  As a result, the rear floor pan 12, the rear floor cross member 24, and the jack-up point member 26 form an exhaust passage 52, and the exhaust hose 48 communicates with the outside space 44 to exhaust the exhaust from the exhaust hose 48 to the outside of the vehicle. Released.

  According to the above configuration, the exhaust from the exhaust hose 48 is separated from the vehicle exterior space 44 by the garage jack bracket 28 via the space 40 formed by the rear floor pan 12, the garage jack reinforcement 30, and the rear floor cross member 24. The air is discharged outside the vehicle through the space 42 (arrows C and B in FIG. 5 indicate the flow direction of the exhaust gas). Therefore, the exhaust gas is diluted in the space 40 formed by the rear floor pan 12, the garage jack reinforcement 30, and the rear floor cross member 24, and then flows into the space 42 that is separated from the vehicle exterior space 44 by the garage jack bracket 28. It is discharged outside the vehicle in a more diluted state.

  Although illustration is omitted, the space 40 may be formed by two members of the rear floor pan 12 and the garage jack reinforcement 30, and the space 42 is formed by two members of the garage jack bracket 28 and the garage jack reinforcement 30. May be.

  As shown in FIG. 6, the exhaust hose 48 is directed outward from the side of the battery 46 in the vehicle width direction, and the intermediate part is bent to extend downward in the vehicle (exhaust hose in the present embodiment). In FIG. 1, the arrangement of 48 is indicated by reference numeral 48 of an imaginary line (two-dot chain line). The front end portion 48A of the exhaust hose 48 is disposed inside the rear floor cross member 24 (in the space 38) while penetrating the rear floor pan 12, and is displaced from the upper side of the garage jack bracket 28 in the jack up point member 26. It is arranged at the position.

  In the bottom 24Z of the rear floor cross member 24, no discharge hole (discharge hole 24B in the first embodiment (see FIG. 3)) is formed above the garage jack bracket 28 in the jack-up point member 26. A discharge hole 24 </ b> C is formed through the position shifted from the attachment portion of the jack-up point member 26. Moreover, the discharge holes 28A and 30A (refer FIG. 3) in 1st Embodiment are not formed in the member 26 for jackup points.

  As a result, the rear floor pan 12 and the rear floor cross member 24 form an exhaust passage 54, and the exhaust hose 48 is communicated with the outside space 44 to release the exhaust from the exhaust hose 48 to the outside of the vehicle. .

  According to the above configuration, the exhaust from the exhaust hose 48 is discharged outside the vehicle through the discharge hole 24C from the space 38 formed by the rear floor pan 12 and the rear floor cross member 24 (an arrow D in FIG. Indicates the direction of exhaust flow.)
