In addition, the vehicle front side end portion of the luggage door hinge arm 310 is rotatably attached with the rotation shaft 302 as an axis. Although not shown, the luggage door hinge arms 310 are provided at two locations in the vehicle width direction.

  A luggage door 320 is attached to the rear end of the luggage door hinge arm 310 in the vehicle. The luggage door 320 can open and close the opening portion of the rear portion of the vehicle 100.

  A luggage door hinge torsion bar 304 is attached to the rotation shaft 302 of the hinge mechanism 300. The luggage door 320 is urged in the opening direction by the urging force of the luggage door hinge torsion bar 304. Note that the luggage door 320 constitutes part of the upper wall and the rear wall of the rear portion of the luggage compartment 100 in a state in which the luggage door 320 is closed.

  The upper end portion of the room partition panel 102 is bent in a hat shape in cross section on the vehicle rear side, and the tip end portion is joined to the upper back panel 110. In addition, the vehicle front portion of the upper back panel 110 is curved downward, and the tip portion is joined to the room partition panel 102. The room partition panel 102 and the upper back panel 110 form a closed section structure portion 112 extending in the vehicle width direction. Note that the cross-sectional shape of the closed cross-section structure portion 112 is a substantially square shape.

  An upper back panel reinforcement 114 having a cross-sectional hat shape and extending in the vehicle width direction is joined between the closed cross-section structure portion 112 and the hinge mechanism 300 in the upper back panel 110. The upper back panel reinforcement 114 and the upper back panel 110 form a closed cross section having a substantially square cross section.

  The vehicle battery device 350 has a substantially rectangular parallelepiped shape as a whole. The vehicle battery device 350 includes a battery main body 351 and a holding portion 353 that holds the battery main body 351. Attachment portions 352 and 354 are provided on the vehicle front side and the vehicle rear side of the holding portion 353 of the vehicle battery device 350, respectively. Then, a vehicle front side mounting portion 352 of the vehicle battery device 350 is bolted to the closed cross-section structure portion 112 (lower portion of the front end of the upper back panel 110), and the vehicle rear side mounting portion 354 is an upper back panel lean. A bolt is fastened to the force 114.

  The vehicle battery device 350 is disposed close to the lower surface 110 </ b> A of the upper back panel 110. The upper surface 350A of the vehicle battery device 350 and the lower surface 110A of the upper back panel 110 are not in contact with each other, and a gap is provided.

  Next, the operation of this embodiment will be described. FIG. 4 shows a vehicle battery device mounting structure to which the present invention is not applied, specifically, a luggage compartment 910 in which the vehicle battery device 950 is mounted on the rear floor panel 906.

  Conventionally, the space below the upper back panel 110 (see the space X in FIG. 4) could not be effectively used as a luggage compartment. On the other hand, in the present embodiment, as shown in FIG. 1, since the vehicle battery device 350 is disposed close to the lower surface 110 </ b> A of the upper back panel 110, a space below the upper back panel 110 is provided. Effective use. And the space above the floor surface 104 that can be effectively used as a cargo space is widened in this embodiment, corresponding to the space effectively used in this way (see the space X in FIG. 4). Furthermore, the floor surface 104 is flat up to the back of the luggage compartment 100 (the front end of the vehicle). Therefore, the utility of the luggage compartment 100 is improved. That is, the convenience of the luggage room 100 is good.

  For example, as shown in FIG. 4, in a vehicle battery device mounting structure to which the present invention is not applied, a long and large luggage M does not enter the luggage compartment 910 (the luggage M protrudes from the luggage compartment 910). ).

  On the other hand, when the vehicle battery device mounting structure of the present embodiment is applied, the luggage M protrudes from the luggage compartment 100 even if it is a long and large luggage M, as shown in FIG. It can be installed without. In addition, since the floor surface 104 is flat to the back (vehicle front end), the luggage M can be mounted horizontally. That is, the utility is improved in the luggage room 100 than in the luggage room 910. That is, the luggage room 100 is more convenient to use.

  In recent years, as a tendency of design for improving aerodynamic performance, the rear window glass 16 has a tendency to be set at an angle closer to the horizontal (the rear window glass 16 has a tendency to be sprinkled). For this reason, the upper back panel 110 tends to become larger (wider) in the vehicle front-rear direction. Therefore, the space (area X in FIG. 4) that could not be effectively used as a cargo room below the upper back panel 110 also tends to increase. Therefore, it is preferable to apply this mounting structure in a tendency that the rear window glass 16 is set at an angle closer to the horizontal.

  In order to increase the utility of the luggage compartment 100 as much as possible and to secure the space of the hinge mechanism 300 (for example, to secure the movable space of the luggage door hinge torsion bar 304), It is desirable to arrange it as far as possible in the front of the vehicle.

  Further, the closed cross-section structure portion 112 has high rigidity. Further, the upper back panel 110 is reinforced by the upper back panel reinforcement 114 to increase its rigidity. The mounting portion 352 of the vehicle battery device 350 is bolted to the closed cross-section structure portion 112, and the mounting portion 354 is bolted to the upper back panel reinforcement 114. Therefore, for example, the vehicle battery device 350 that is heavier than the vehicle battery device 350 attached directly to the upper back panel 110 can be attached.

  Moreover, since the upper back panel 110 is reinforced by the upper back panel reinforcement 114 and the vehicle battery device 350 functions as a strength member, the rigidity of the upper back panel 110 and the room partition panel 102 is increased. . Therefore, the vibrations of the upper back panel 110 and the room partition panel 102 are reduced. Therefore, the transmitted sound level to the vehicle compartment 12 is improved (the quietness of the vehicle compartment 12 is improved).

  When the upper back panel 110 has a sufficiently high rigidity, the upper back panel reinforcement 114 may not be joined to the upper back panel 110. In this case, the attachment portion 354 of the vehicle battery device 350 may be bolted to the upper back panel 110 via a bracket or the like.

  Next, the vehicle 11 on which the vehicle battery device is mounted will be described with reference to FIG. 3 using the mounting structure for the vehicle battery device according to the second embodiment of the present invention. The arrow UP indicates the vehicle upward direction, and the arrow OUT indicates the vehicle width direction outer side. In addition, the same members as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 3 is a longitudinal sectional view along the vehicle width direction of the luggage compartment 200 disposed in the rear portion of the vehicle 11. The direction orthogonal to the drawing is the vehicle front-rear direction. More specifically, the rear side of the figure is the front direction of the vehicle, and the front side of the figure is the rear side of the vehicle.

  Wheel houses 202 and 212 are provided on both outer sides of the vehicle rear portion of the vehicle 11 in the vehicle width direction. The wheel houses 202 and 212 include wheel house inners 204 and 206 that constitute an inner side in the vehicle width direction and wheel house outers 206 and 216 that constitute an outer side in the vehicle width direction.

  The wheel house outers 206 and 216 have extension portions 206B and 216B extending upward from the joint portions 206A and 216A with the wheel house inners 204 and 214, respectively. Further, wheel house cassettes 208 and 218 are disposed outside the wheel house outers 206 and 216 in the vehicle width direction. The wheel house inners 204 and 214 and the extension portions 206B and 216B of the wheel house outers 206 and 216 constitute part of the side walls 220 and 222 on the outer side in the vehicle width direction of the luggage compartment 200.

  In addition, brackets 230 and 232 are joined to the extending portions 206B and 216B of the wheel house outer 206 and 216 by spot welding or the like.

  The vehicle battery device 360 has a substantially rectangular parallelepiped shape as a whole. The vehicle battery device 360 includes a battery main body 361 and a holding portion 363 that holds the battery main body 361. Note that the overall shape of the vehicle battery device 360 of the present embodiment is thinner in the vertical direction and longer in the vehicle width direction than the vehicle battery device 350 of the first embodiment (see FIG. 1).

  Attachment portions 362 and 364 are provided on both outer sides of the holding portion 363 of the vehicle battery device 360 in the vehicle width direction. The mounting portions 362 and 364 of the vehicle battery device 360 are bolted to the brackets 230 and 232 joined to the extending portions 206B and 216B of the wheel house outers 206 and 216, respectively.

  The vehicle battery device 360 is disposed close to the lower surface 210 </ b> A of the upper back panel 210 that constitutes the upper wall of the luggage compartment 200. The upper surface 360A of the vehicle battery device 360 and the lower surface 210A of the upper back panel 210 are not in contact with each other, and a gap is provided.

  The wheel houses 202 and 204 are integrally formed with a rear suspension tower (not shown), and the rear suspension tower is configured to connect a wheel (rear wheel) (not shown) of the vehicle 11 to a suspension (rear suspension) (not shown). Support through.

  Next, the operation of this embodiment will be described.

  This embodiment also has the same effect as the first embodiment, but the vehicle battery device 360 of this embodiment is thinner in the vertical direction than the vehicle battery device 350 of the first embodiment (see FIG. 1). Therefore, the space between the lower surface 360B of the vehicle battery device 360 and the rear floor panel 209 constituting the floor surface 211 of the luggage compartment 200 is increased accordingly. Therefore, the utility is further improved.

  Further, the wheel houses 202 and 204 have a rigidity capable of receiving a rear suspension input since a rear suspension tower (not shown) is integrally formed. That is, the wheel houses 202 and 204 have high rigidity. Therefore, the heavy vehicle battery device 360 can be attached without requiring additional reinforcement for attaching the vehicle battery device 360. Furthermore, the brackets 230 and 232 joined to the extending portions 206B and 216B of the wheel house outer 206 and 216 are the wheel houses 202 and 204 as in the upper back panel reinforcement 114 (see FIG. 1) of the first embodiment. The function to reinforce is not necessary. Therefore, the brackets 230 and 232 are lighter than the upper back panel reinforcement 114 of the first embodiment, and can be provided at a low cost.

  In addition, this invention is not limited to the said embodiment.

  For example, in both the first embodiment and the second embodiment, only the vehicular electric devices 350 and 360 are mounted, but a vehicular electric device different from the vehicular electric devices 350 and 360 is used as the luggage compartment 100, 200 may be mounted. For example, a vehicle electrical device different from the vehicle electrical devices 350 and 360 may be arranged on the rear floor panels 106 and 209.

  For example, in the case where the number of vehicle battery devices is increased by plug-in HV or the like that can be charged from a household outlet, the configuration in which two vehicle battery devices are arranged vertically on the rear floor panel is arranged. However, when one vehicle battery device is disposed in contact with or close to the upper back panel and the other is disposed on the rear floor panel, the convex portion of the floor surface is lowered. That is, the space that can be effectively used as a cargo room above the floor surface is increased, compared to a configuration in which two vehicle battery devices are arranged in the vertical direction on the rear floor panel. Thus, the utility is improved.

  Further, for example, in both the first embodiment and the second embodiment, the vehicle electrical devices 350 and 3608 (the upper surfaces 350A and 360A thereof) and the lower surfaces 110A and 210A of the upper back panels 110 and 210 are not in contact with each other. However, the gap is provided, but the present invention is not limited to this. The vehicle electrical devices 350 and 360 and the lower surfaces 110A and 210A of the upper back panels 110 and 210 may be in contact with each other.
