JP, 2011-83111, A

  As disclosed in Patent Document 1 described above, a vehicle equipped with a plug-in type charger is known. In such a vehicle, from the viewpoint of reducing the influence on the space of the luggage room (luggage compartment), it is conceivable to arrange the charger below the spare tire stored under the floor of the luggage room. However, in this case, the ambient temperature in the storage space for the spare tire may excessively rise due to the exhaust heat from the charger.

  Therefore, an object of the present disclosure is to solve the above problems, and to provide a vehicle capable of appropriately treating exhaust heat from a charger with a simple configuration.

  A vehicle according to the present disclosure includes an interior material that defines a luggage room of the vehicle, a body provided outside the interior material when viewed from the inside of the luggage room, a spare tire stored under the floor of the luggage room, and a body. And a support material for supporting the spare tire. A first space is provided between the support material and the body below the spare tire. The vehicle further includes a charger arranged in the first space. A second space is provided between the interior material and the body. The support member forms an intake passage that sucks air toward the first space and an exhaust passage that discharges air from the first space toward the second space.

  According to the vehicle configured as described above, the exhaust heat from the charger is transferred from the first space to the second space by forming the air flow that sequentially flows through the intake passage, the first space, the exhaust passage, and the second space. It is possible to guide and further radiate heat to the outside of the vehicle through the body in the second space. At this time, since the intake passage and the exhaust passage are formed by the support material that supports the spare tire, the exhaust heat from the charger can be appropriately treated with a simple configuration.

  As described above, according to the present disclosure, it is possible to provide a vehicle capable of appropriately processing the exhaust heat from the charger with a simple configuration.

  The vehicle 10 further includes a support member 37. The support member 37 is configured to support the spare tire 41 under the floor of the luggage room 20. The support member 37 is provided on the rear floor panel 31p so as to receive the weight of the spare tire 41. The support material 37 is formed of a foam material. The support material 37 is provided as a cushioning material that suppresses the transmission of vibration and shock to the spare tire 41.

  The support member 37 is provided on the body 31 (more specifically, the rear floor panel 31p). The support member 37 is fitted in the recess 32.

  The structure of the support member 37 will be specifically described. The support member 37 includes a tire receiving portion 37i and a disc portion 37h as its constituent parts.

  The tire receiving portion 37i has an annular saucer shape capable of accommodating the tire portion 43. The tire receiving portion 37i is in contact with the inner wall of the body 31 defining the recess 32 on the outer periphery thereof. The disc portion 37h is provided inside the tire receiving portion 37i. The disc portion 37h extends in a disc shape (disc shape) immediately below the wheel portion 42 of the spare tire 41.

  The vehicle 10 further includes a lid member 36. The lid member 36 is combined with the support member 37 so as to cover the spare tire 41 supported by the support member 37.

  A first space 51 is provided between the support material 37 and the body 31. More specifically, the first space 51 is provided between the disc portion 37h and the rear floor panel 31p. The first space 51 is provided inside the annular tire receiving portion 37i.

  The charger 28 is arranged in the first space 51. The charger 28 is fixed to the rear floor panel 31p in the first space 51. The vehicle 10 further includes a fan 29. The fan 29 is arranged in the first space 51 together with the charger 28.

  As shown in FIG. 1, the support member 37 forms an intake passage 40. The intake passage 40 is formed by a gap between the support member 37 and the inner wall of the body 31 defining the recess 32. The intake passage 40 is formed so that the accommodation space 53 of the battery 26 and the first space 51 communicate with each other.

  As shown in FIGS. 1 and 4, the support member 37 further forms an exhaust passage 38 and an exhaust passage 39. The exhaust passage 38 and the exhaust passage 39 are formed by a gap between the support member 37 and the inner wall of the body 31 defining the recess 32. In order to provide a gap between the support material 37 and the inner wall of the body 31 that defines the recess 32, the support material 37 (more specifically, the tire receiving portion 37i) is provided with a cutout portion. The notch has a concave shape that is recessed from the outer peripheral edge of the tire receiving portion 37i. The exhaust passage 38 and the exhaust passage 39 are formed to communicate between the first space 51 and the second space 52 (more specifically, the second space 52A).

  The intake passage 40 is located on the vehicle front side of the support member 37. The exhaust passage 38 and the exhaust passage 39 are located on the vehicle rear side of the support member 37. The exhaust passage 38 and the exhaust passage 39 are located apart from each other in the vehicle width direction. The intake passage 40 and the exhaust passage 38 and the exhaust passage 39 are located apart from each other in the vehicle front-rear direction.

  As shown by the arrow in FIG. 1, as the fan 29 is driven, an air flow that flows in order through the intake passage 40, the first space 51, the exhaust passages 38, 39, and the second space 52 is formed.

  More specifically, air is introduced from the accommodation space 53 of the battery 26 toward the first space 51 through the intake passage 40. The air whose temperature has risen due to the exhaust heat from the charger 28 in the first space 51 is discharged to the second space 52A through the exhaust passage 38 and the exhaust passage 39. Further, as shown by the arrows in FIGS. 2 and 3, the high-temperature air discharged from the first space 51 flows from the second space 52A to the second space 52B and the second space 52C. While the air flows through the second spaces 52, the exhaust heat from the charger 28 is radiated to the outside of the vehicle via the body 31.

  If the exhaust heat from the charger 28 is sucked and exhausted only in the first space 51, the ambient temperature of the first space 51 may extremely rise, which may adversely affect the operation of the charger 28. Further, it is conceivable to provide a duct to exhaust the exhaust heat from the charger 28 into the luggage room 20, but in this case, the temperature of the luggage (particularly food) loaded in the luggage room 20 excessively rises. .. Further, it is conceivable to provide a duct to exhaust the exhaust heat from the charger 28 into the vehicle interior, but in this case, the temperature inside the vehicle interior may rise and the occupant may feel uncomfortable.

  On the other hand, in the present embodiment, by providing the intake passage 40 and the exhaust passages 38, 39, the exhaust heat from the charger 28 can be radiated to the outside of the vehicle via the body 31. At this time, since the interior material 21 generally has high heat insulation performance, the temperature inside the luggage room 20 does not extremely rise due to the exhaust heat from the charger 28. Further, since the intake passage 40 and the exhaust passages 38, 39 are formed by the support material 37 that supports the spare tire 41, it is not necessary to provide a new duct under the floor of the luggage room 20.

  The structure of the vehicle 10 according to the embodiment of the present disclosure described above will be collectively described. The vehicle 10 according to the present embodiment includes the interior material 21 that partitions and forms the luggage room 20 of the vehicle and the inside of the luggage room 20. As seen, the body 31 is provided outside the interior material 21, a spare tire 41 stored under the floor of the luggage room 20, and a support material 37 provided on the body 31 and supporting the spare tire 41. A first space 51 is provided below the spare tire 41 between the support material 37 and the body 31. The vehicle 10 further includes the charger 28 arranged in the first space 51. A second space 52 is provided between the interior material 21 and the body 31. The support member 37 forms an intake passage 40 for sucking air toward the first space 51 and exhaust passages 38, 39 for discharging air from the first space 51 toward the second space 52.

  According to vehicle 10 in the embodiment of the present disclosure configured as described above, exhaust heat from charger 28 can be appropriately processed with a simple configuration.

  The embodiments disclosed this time are to be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description but by the claims, and is intended to include meanings equivalent to the claims and all modifications within the scope.
