Description

[Technical field]

[0001] The present invention relates to a vehicle interior structure having a drive battery case mounted above a floor panel in a vehicle such as a hybrid vehicle or an electric vehicle. [Background technology]

[0002] In vehicles such as hybrid cars and electric cars, a vehicle interior configuration in which a drive battery is mounted above a floor panel is known in which the battery is laid out (disposed) above the rear floor of the luggage compartment, as exemplified in Patent Document 1.

[0003] However, attempting to mount the drive battery above the rear floor of the luggage compartment while maintaining battery capacity would raise the luggage compartment floor level, resulting in an insufficient effective height of the luggage compartment space; this problem is particularly pronounced in style-oriented vehicles with low roof heights.

[0004] Also, as exemplified in Patent Document 2, a proposal has been made to lay out the drive battery, i.e., the drive battery case provided for the drive battery, in the area below the rear seat cushion located above the floor panel. However, this increases the height of the rear seat cushion, resulting in a problem of insufficient headroom for rear seat occupants.

[0005] Furthermore, even if one attempts to form a flat, expanded luggage compartment floor by tilting the rear seat backrest forward and expanding the luggage compartment floor to the area of ​​the vehicle interior floor where the rear seats are installed, as described above, it becomes difficult to form a flat, expanded luggage compartment floor because the drive battery case mounted above the floor panel is bulky. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2005-71759 A [Patent Document 2] JP 2009-29159 A Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention has been made in consideration of these problems, and aims to provide a vehicle interior structure that, in a configuration in which a drive battery case is mounted above the floor panel, ensures the height of the luggage compartment and the height of the rear seat arrangement area within the vehicle cabin without compromising battery capacity, and can increase the area of ​​the flat luggage compartment floor when the rear seat backrests are tilted forward. [Means for solving the problem]

[0008] The present invention relates to a vehicle interior structure having a floor panel forming a floor surface of a vehicle interior, a rear seat portion separated into left and right portions and disposed above the floor panel, a rear seat backrest portion separated into left and right portions and disposed on the side of the rear seat portion so as to be able to be tilted forward from above, and a first driving battery case disposed on the floor panel above a luggage compartment floor surface rearward of the rear seat portion, the first driving battery case being disposed above the floor panel between the left and right rear seat portions, a console covering an upper surface and left and right side surfaces of the second driving battery case, The vehicle is characterized in that it is equipped with an intermediate backrest portion that is disposed between the left and right rear seat backrest portions on the console side and can be tilted forward from above, the front-to-rear thickness of the intermediate backrest portion in an upright state is set to be smaller than the front-to-rear thickness of the left and right rear seat backrest portions, the front end portion of the first driving battery case is disposed close to the rear end portion of the rear seat backrest portion in the forward-tilted state, the upper surfaces of the left and right rear seat backrest portions and the intermediate backrest portion in the forward-tilted state are flush with each other in the vehicle width direction and, together with the upper surface portion of the first driving battery case, form an expanded luggage compartment floor surface.

[0009] According to the above configuration, the height inside the luggage compartment can be kept low when all of the left and right rear seat backrests and the intermediate backrest are tilted forward without compromising the battery capacity, and the area of ​​the flat luggage compartment floor can be increased.

[0010] Here, the above-mentioned phrase "forming an expanded luggage compartment floor surface together with the upper surface of the first driving battery case" also includes the case where the expanded luggage compartment floor surface is formed together with the substantial upper surface of the first driving battery case. Specifically, the upper surface of the first driving battery case is not limited to being exposed toward the luggage compartment space so as to form part of the expanded luggage compartment floor. Even if the upper surface is covered by a covering member such as a decorative panel, mat, luggage compartment partition board, etc., and these covering members form the actual upper surface of the first driving battery case, the upper surface of the first driving battery case is considered to form part of the expanded luggage compartment floor.

[0011] In one aspect of the invention, the floor panel includes a front floor panel having a tunnel portion extending fore and aft, a kick-up portion rising from the rear end of the front floor panel, and a rear seat cushion panel extending rearward from the upper end of the kick-up portion and on which the rear seat seat is mounted, and the second driving battery case is positioned above the rear seat cushion panel and extends forward of the kick-up portion above the tunnel portion.

[0012] According to the above configuration, the height between the left and right rear seats can be kept low while ensuring battery capacity by extending the second driving battery case forward from the kick-up portion. In addition, the top surface of the first driving battery case, which forms part of the expanded luggage compartment floor, extends forward, which contributes to expanding the expanded luggage compartment floor.

[0013] In another aspect of the invention, the upper surface of the console has an intermediate backrest placement section extending in the fore-and-aft direction capable of placing the intermediate backrest section when tilted forward, and a raised section in front of the intermediate backrest placement section that is raised higher than the intermediate backrest placement section, and the surface of the raised section that faces the rear seat occupant in a side view of the vehicle is provided with a functional surface that rises along the shape of the front part of the intermediate backrest section when tilted forward on the upper surface of the console in a side view of the vehicle.

[0014] According to the above configuration, the front portion of the folded-down intermediate backrest portion substantially abuts against or approaches from the rear side against the functional surface, so that the functional surface of the console can be protected by the front portion of the folded-down intermediate backrest portion. Furthermore, the intermediate backrest support portion can firmly support the intermediate backrest portion when it is placed on the intermediate backrest portion in a folded-down position.

[0015] In one embodiment of the present invention, the raised portion and the intermediate backrest portion tilted forward are provided so that their upper surfaces are substantially flush with each other in the fore-and-aft direction of the vehicle. According to the above configuration, the step between the raised portion and the intermediate backrest portion when tilted forward can be eliminated, contributing to a flat luggage compartment floor surface.

[0016] In another aspect of the present invention, the console comprises a base portion and a movable console installed on an upper surface of the base portion, and the movable console is configured to be able to be flipped up relative to the upper surface of the base portion further forward than a forward tilt trajectory that causes the intermediate backrest portion in an upright position to tilt forward onto the upper surface of the base portion.

[0017] According to the above-mentioned configuration, when the intermediate backrest is in the upright position, the rear seat passenger can use the movable console installed on the upper surface of the base, i.e., the rear seat passenger can use, for example, an item storage section, a cup holder, etc., that are appropriately provided on the movable console.

[0018] On the other hand, by flipping the movable console forward relative to the upper surface of the base portion, the intermediate backrest portion can be tilted forward while keeping the height of the upper surface of the intermediate backrest portion low without interfering with the movable console when tilted forward.

[0019] In one embodiment of the present invention, the intermediate backrest portion that is tilted forward is set to a height that allows a rear seat passenger to rest his or her elbows as an armrest for the rear seat. According to the above-mentioned configuration, the rear seat passenger can use the intermediate backrest as an armrest for the rear seat. At that time, since the intermediate backrest is supported from below by the base when tilted forward, the rear seat passenger can stably place his / her elbow on the intermediate backrest as the armrest for the rear seat. Effect of the Invention

[0020] According to the above configuration, in a configuration in which the driving battery case is mounted above the floor panel, the height of the luggage compartment and the height of the rear seat arrangement area within the vehicle cabin can be secured without compromising the battery capacity, and the area of ​​the flat luggage compartment floor when the rear seat backrests are tilted forward can be increased.

In addition, the floor panel 1 forms the floor surface of the passenger compartment 2 other than the luggage compartment 2a (i.e., the floor surface of the passenger compartment in front of the luggage compartment 2a) by the front floor panel 11, the kick-up portion 12, and the rear seat cushion panel 131.

[0028] As shown in FIG. 6, a rear end member 14b extending in the vehicle width direction is joined and fixed to the rear surface of the rear end panel 14a, and a rear end closed cross section 14s extending in the vehicle width direction is formed between this rear end member 14b and the rear end panel 14a, thereby ensuring rear body rigidity.

[0029] As shown in FIG. 6, the vehicle V of this embodiment is configured as a hatchback type having a rear gate opening 15 at the rear that opens toward the rear and a rear gate 16 that covers the rear gate opening 15 in an openable and closable manner.

[0030] The rear gate 16 includes a rear gate inner panel 17, a rear gate outer panel 18, and a rear window 19. Of these, the rear gate inner panel 17 is covered from the passenger compartment 2 side by a rear gate trim 171 serving as an interior member.

[0031] Further, the vehicle V is provided with a roof panel 20 made of a steel plate as a roof, and the roof panel 20 is covered from the inside of the passenger compartment 2 with a roof trim 21 as an interior member. The roof trim 21, the rear gate trim 171, the rear window 19, etc. define the height dimension of the interior of the vehicle compartment 2, including the luggage compartment 2a, excluding the front part.

[0032] Furthermore, as shown in Figures 1, 5 and 6, the above-mentioned front floor panel 11 has a tunnel portion 22 extending in the fore-and-aft direction between the dash lower panel 4 (dash panel) (see Figure 6) and the vertical wall-shaped kick-up portion 12 and protruding toward the inside of the passenger compartment 2.

[0033] The tunnel portion 22 is the center of the vehicle body rigidity, and its rear end portion is joined to the kick-up portion 12. The kick-up portion 12 is formed in a vertical wall shape that is higher than the rear end portion of the tunnel portion 22.

[0034] A plurality of cross members 23, 24 (vehicle body rigidity members) spaced apart in the front-rear direction are joined from above to both sides of the tunnel portion 22 of the front floor panel 11. The cross members 23, 24 extend in the vehicle width direction so as to connect the left and right vertical wall portions of the tunnel portion 22 to the left and right side sills 5 (more specifically, side sill inners 5a) (only the left side of the vehicle is shown in FIG. 5) as vehicle body rigidity members, and closed cross sections 23s, 24s extending in the vehicle width direction are formed between the cross members 23, 24 and the front floor panel 11, as shown in FIGS. 1 and 6.

[0035] 1 and 6, multiple rear cross members 25, 26 (vehicle body rigidity members) spaced apart in the fore-and-aft direction are joined to the rear floor panel 13. The front-end rear cross member 25 (No. 3 cross member) is joined downward to the front end of the rear floor panel 13 (i.e., the front end of the rear seat cushion panel 131) and from behind the kick-up portion 12, and a closed cross section 25s extending in the vehicle width direction is formed between the corner portion of the rear floor panel 13 and the kick-up portion 12.

[0036] The intermediate rear cross member 26 (No. 4 cross member) faces the rear floor panel 13 on both the top and bottom sides and is equipped with an intermediate rear cross member upper 26a which has a hat-shaped cross section that opens downward, and an intermediate rear cross member lower 26b which faces the rear floor panel 13 on both the top and bottom sides and is also equipped with a hat-shaped cross section that opens upward.

[0037] The intermediate rear cross member upper 26a and the intermediate rear cross member lower 26b are joined so as to sandwich the rear end of the rear seat cushion panel 131 between their respective front end flange portions, and are also joined so as to sandwich the front end of the luggage compartment floor panel 132 between their respective rear end flange portions, forming a closed cross-section 26s extending in the vehicle width direction between them.

[0038] Of the pair of left and right front seats 27, 28 mentioned above, the driver's seat 27 (in this example, the front seat 27 on the right side of the vehicle) is equipped with a seat cushion 27C that forms the seating surface for the occupant, a seat back 27B that extends upward from the rear end of the seat cushion 27C to form the backrest surface for the occupant, and a headrest 27H that is provided on the upper part of the seat back 27B to support the head of the occupant.

[0039] Similarly, as shown in Figures 1 and 5, the passenger seat 28 (in this example, the front seat 28 on the left side of the vehicle) of the pair of left and right front seats 27, 28 described above is equipped with a seat cushion 28C that forms a seating surface for the occupant, a seat back 28B that extends upward from the rear end of the seat cushion 28C to form a backrest surface for the occupant, and a headrest 28H that is provided on the upper part of the seat back 28B and supports the head of the occupant.

[0040] 1 to 6, a front seat center console portion 50 is provided between the driver's seat 27 and the passenger seat 28, i.e., in the middle in the vehicle width direction, to separate the seat cushions 27C, 28C of the left and right front seats 27, 28 in the vehicle width direction. The front seat center console portion 50 will be described in detail later.

[0041] 1 and 5, the pair of left and right rear seats 30, 31 are provided behind the pair of left and right front seats 27, 28 and disposed above the rear seat cushion panel 131. The pair of left and right rear seats 30, 31 include seat cushions 30C, 31C forming a seating surface for an occupant, seat backs 30B, 31B extending upward from the rear ends of the seat cushions 30C, 31C forming a backrest surface for the occupant, and headrests 30H, 31H provided on the upper parts of the seat backs 30B, 31B to support the head of the occupant.

[0042] In addition, between the left and right rear seats 30, 31, i.e., in the middle in the vehicle width direction, a rear seat center console portion 70 is provided that separates the seat cushions 30C, 31C of the left and right rear seats 30, 31 in the vehicle width direction, and between the seat backs 30B, 31B of the left and right rear seats 30, 31, i.e., in the middle in the vehicle width direction, an intermediate backrest portion 32 is provided.

[0043] The left and right rear seats 30, 31 are separated in the vehicle width direction and partitioned by the rear seat center console portion 70 and the intermediate seat backrest portion 32, ensuring their independence from each other. The rear seat center console portion 70 will be described in detail later.

[0044] The intermediate backrest portion 32 includes an intermediate backrest main body portion 33 and a rear seat armrest 34. The rear seat armrest 34 is configured to be able to rise and fall (to collapse forward or stand up) around a fulcrum 36 (armrest fulcrum) shown in FIG. 6 that is provided at the bottom of the intermediate backrest main body portion 33.

[0045] 1, the rear seat armrest 34 normally stands up and forms the front surface of the upper part of the intermediate backrest portion 32. On the other hand, as shown in FIGS. 4 and 7, the rear seat armrest 34 becomes a horizontal armrest when it is folded forward (i.e., folded forward).

[0046] Incidentally, each of the seat backs 30B, 30B of the pair of left and right rear seats 30, 31 described above is configured to be movable so as to be tiltable forward as shown in FIG. 4 via a fulcrum 37 (seat back rotation fulcrum) (see FIG. 6) provided independently of each other at the lower part.

[0047] Similarly, the intermediate backrest portion 32 is configured to be movable so as to be tiltable forward as shown in FIG. 4 via another fulcrum 38 (seatback rotation fulcrum) (see FIG. 6) located lower than the above-mentioned fulcrum 36 (armrest rotation fulcrum).

[0048] The lower part of the intermediate backrest portion 32 is pivotally supported via the above-mentioned fulcrum 38 to a bracket (not shown) erected from the rear seat cushion panel 131, but this configuration is not limited thereto, and the lower part may be pivotally supported directly via the fulcrum 38 to the left and right rear seats 30, 31 or the second driving battery case 44 described later, or indirectly by using a bracket or the like.

[0049] 7, the front-to-rear thickness (L32) of the intermediate backrest portion 32 in the upright state is set to be smaller than the front-to-rear thickness (L30B) of the seat backs 30B, 31B of the left and right rear seats 30, 31. Although not shown, the front-to-rear thickness of the seat back 31B of the left rear seat 31 is set to be the same as the front-to-rear thickness (L30B) of the seat back 30B of the right rear seat 31. As a result, as shown in Figures 4 and 8, in the vehicle V of this embodiment, when the seat backs 30B, 31B are folded forward onto the upper parts of the corresponding pair of left and right seat cushions 30C, 31C and the intermediate backrest portion 32 is folded forward onto the upper part of the corresponding rear seat center console portion 70, the upper surface portions 30Bu, 31Bu of the pair of left and right seat backs 30B, 31B and the upper surface portion 32u of the intermediate backrest portion 32 become approximately flush with each other.

[0050] (Basic structure of first and second drive batteries 41, 42) 1, 2, and 7, the vehicle V of this embodiment is a plug-in hybrid electric vehicle (PHEV) and is therefore equipped with drive batteries 41, 42. The vehicle V of this embodiment is equipped with a first drive battery 41 and a second drive battery 42 as the drive batteries 41, 42, both of which are disposed above the floor panel 1.

[0051] Each of the first and second driving batteries 41, 42 includes one or more battery packs (not shown). The battery packs of this embodiment are housed in battery cases 43, 44, and are configured by connecting a large number of batteries (cells) in series inside the battery cases 43, 44.

[0052] The batteries constituting the battery pack may be any of lead-acid batteries, lithium-ion batteries, and nickel-metal hydride batteries, or may be secondary batteries other than these. Furthermore, the battery mounted on the vehicle V may be not only a secondary battery, but also a fuel cell or the like. The battery cases 43, 44 of the first and second driving batteries 41, 42 are each formed, for example, by aluminum die casting to ensure a predetermined rigidity, and as shown in FIG. 5, the upper surface portions 43u, 44u of each are formed in a horizontal plane.

[0053] (First drive battery 41) As shown in FIGS. 1, 5 and 7, the first driving battery 41 is disposed in a space below the luggage compartment 2a located behind the left and right rear seats 30, 31. The battery case 43 of the first driving battery 41 (hereinafter referred to as the "first driving battery case 43") extends linearly in the vehicle width direction and is disposed from above over substantially the entire length in the vehicle width direction in the front part of the luggage compartment floor panel 132 that forms the floor surface of the luggage compartment 2a. The first driving battery case 43 is formed so that the rear central part in the vehicle width direction bulges downward relative to the front part, and the rear downward bulging part of the luggage compartment floor panel 132 is housed in the front part of a recess 132a for accommodating a spare tire.

[0054] As shown in FIG. 5, the first driving battery case 43 is attached to the intermediate rear cross member 26 and the rear side frames 3, which serve as vehicle body rigidity members on both sides of the luggage compartment floor panel 132, via appropriate brackets 45 or the like using bolts and nuts as fastening members.

[0055] As shown in Figures 4 and 8, the first driving battery case 43 has its front end 43f positioned close to the rear end portions 30Br, 31Br of the seat backs 30B, 31B in the forward-tilted state of the rear seats 30, 31, and is positioned with almost no gap in the fore-and-aft direction relative to the seat backs 30B, 31B in the forward-tilted state.

[0056] Furthermore, as shown in FIG. 4, the first driving battery case 43 is positioned so that the upper surface portion 43u is flush in the fore-and-aft direction with the respective upper surface portions 30Bu, 31Bu, 32u of the seat backs 30B, 31B and intermediate backrest portion 32 of the left and right rear seats 30, 31 when tilted forward.

[0057] 1, 4 and 6, a luggage compartment partition board 40 that separates the rear of the luggage compartment 2a into upper and lower parts is removably provided horizontally above the luggage compartment floor panel 132 and behind the rear end of the first driving battery case 43. The height of the luggage compartment partition board 40 is set so that the upper surface 40u is approximately the same height as the upper surface 43u of the first driving battery case 43.

[0058] Therefore, when the luggage compartment partition board 40 is installed above and behind the luggage compartment floor panel 132, the flat upper surfaces 43u, 40u of the first driving battery case 43 and the luggage compartment partition board 40 form an actual luggage compartment floor surface 2F that is different from the luggage compartment floor surface formed by the upper surface portion of the luggage compartment floor panel 132 (see Figures 6 and 7).

[0059] Furthermore, as shown in Figures 4 and 8, when the seat backs 30B, 31B and the intermediate backrest portions 32 of the left and right rear seats 30, 31 are tilted forward, the upper surfaces 30Bu, 31Bu, 32u of these members 30B, 31B, 32 (i.e., the back surfaces under normal conditions) become approximately flush with the upper surfaces 43u, 40u of the first driving battery case 43 and the luggage compartment partition board 40.

[0060] In other words, the actual luggage compartment floor surface 2F formed by each upper surface portion 43u, 40u is expanded to the space around the rear seats 30, 31 by each upper surface portion 30Bu, 31Bu, 32u, and is configured to form a flat expanded luggage compartment floor surface 2Fa capable of carrying a large amount of cargo, as shown in Figures 4 and 8.

[0061] Although not shown, the seat backs 30B, 31B and the middle backrest portion 32 of the left and right rear seats 30, 31 can be folded forward independently, so it is not necessary to fold forward any one of the seat backs 30B, 31B, 32. This allows the passenger to sit on the rear seats 30, 31 without folding forward any of the seat backs 30B, 31B, and expands the space of the luggage compartment 2a. The luggage compartment partition board 40 is not essential, and may be omitted. Furthermore, the luggage compartment partition board 40 may be extended forward so as to be installed from above on the upper surface portion 43u of the first driving battery case 43, and the forward extension portion of the luggage compartment partition board 40 may form the substantial upper surface portion (43u) of the first driving battery case 43.

[0062] (Second drive battery 42) As shown in FIGS. 2, 5 and 7, the second driving battery 42 is disposed between the seat cushions 30C, 31C of the left and right rear seats 30, 31 in the vehicle width direction. In detail, the second driving battery 42 is arranged above the rear seat cushion panel 131, but is not arranged, for example, below the seat cushions 30C, 31C of the left and right rear seats 30, 31, but is arranged in a straight line in the fore-and-aft direction only between the seat cushions 30C, 31C of the left and right rear seats 30, 31 in the vehicle width direction of the rear seat cushion panel 131.

[0063] The battery case 44 of the second driving battery 42 (hereinafter referred to as the "second driving battery case 44") is attached and fixed to the upper surface of the rear seat cushion panel 131 with fastening members consisting of bolts and nuts (not shown). As shown in Fig. 7, the rear end 44r of the second driving battery case 44 is located close to the front end 43f of the middle part in the vehicle width direction of the first driving battery case 43, and extends forward in a straight line.

[0064] As a result, the first and second driving battery cases 43, 44 are configured as a whole in a roughly T-shape in plan view. Furthermore, as shown in Figures 2, 5, and 7, the front portion of the second driving battery case 44 extends horizontally forward of the kick-up portion 12 along the tunnel portion 22, and is positioned above and spaced apart from the upper surface portion 22u of the tunnel portion 22 (see Figure 2). Although not shown, in this embodiment, the battery pack inside the second driving battery case 44 is configured by arranging multiple batteries in series in the front-rear direction to correspond to the second driving battery case 44 extending in the front-rear direction. Therefore, by extending the second driving battery case 44 forward from the kick-up portion 12, the battery capacity of the second driving battery 42 is ensured.

[0065] 1, 2, 5, 7 and 8, particularly FIG. 8, the second driving battery case 44 has a front end 44F that extends forward of the rear end 50r of the front seat center console portion 50 so as to be fitted into the front seat center console portion 50 from the rear. The front end 44F of the second driving battery case 44 is supported inside the front seat center console portion 50 by the tunnel portion 22 via a mounting member 67 (FIG. 7) described later. As a result, the front portion of the second driving battery case 44 (that is, the portion extending forward from the kick-up portion 12) is horizontally bridged (suspended) between the mounting member 67 and the rear seat cushion panel 131.

[0066] (Front seat center console part 50) As shown in Figures 1 and 5, the above-mentioned front seat center console section 50 is erected on the upper surface 22u of the tunnel section 22, and a portion near its front end is connected to the lower part of the central portion in the vehicle width direction of the instrument panel 7 (see Figure 6) which extends in the vehicle width direction at the front side of the passenger compartment 2.

[0067] As shown in Figures 1, 5, 6 and 7, the front seat center console section 50 mainly includes a cover member 51 as an interior member having a hollow box shape, a shift lever 52, an item storage section 53, a lid 57, an attachment member 67 (see Figure 7) that supports the item storage section 53, and a rear seat supply duct 62 (see Figures 6 and 7).

[0068] As shown in Figures 1 and 5, the cover member 51 comprises a pair of left and right side portions 511 (see Figure 10) that face each other in the vehicle width direction and form the sides of the front seat center console portion 50, a top surface portion 512 that is disposed between the left and right side portions 511 and forms the front portion of the upper surface of the front seat center console portion 50, and a rear surface portion 513 (see Figure 5) that is disposed above the rear end portion 50r of the front seat center console portion 50, all of which are decorative panels.

[0069] The shift lever 52 is a lever that receives an operation by a passenger to change the gears of a transmission (not shown) of the vehicle V. The shift lever 52 is disposed in a position on the front side of the top surface portion 512 and on the central side in the vehicle width direction.

[0070] As shown in Fig. 7, the item storage section 53 is provided at the rear of the front seat center console section 50. The item storage section 53 has a bottom wall 531, a pair of left and right side walls 352 (see Fig. 10) rising from both side edges of the bottom wall 531, a front wall 533 rising from the front edge of the bottom wall 531, and a rear wall 534 rising from the rear edge of the bottom wall 531, and is formed in a bottomed rectangular tube shape provided with an opening 56 that opens upward. The opening 56 of the item storage section 53 is provided rearward of the top surface section 512 of the front seat center console section 50. In addition, the item storage section 53 in this embodiment has a depth that allows a tablet terminal to be placed vertically.

[0071] The lid 57 is provided on the upper part of the item storage section 53 so as to be able to close the opening 56 . The lid 57 includes a pair of left and right split lids 571, 571 capable of opening and closing the opening 56 above the item storage section 53. As shown in Fig. 10, pivotal attachment parts 58 are provided on the left and right side edges 156 of the opening 56 on the rear upper surface of the front seat center console section 50, which pivotally attach the left and right split lids 571, 571 to the side edges 156 via shafts 58a extending along the front-rear direction. As a result, the pair of left and right split lids 571, 571 are configured as double doors (double-door type) that open the opening 56 from the center.

[0072] The lid 57 is configured to have sufficient strength and cushioning properties to function as an armrest when the opening 56 is closed. Furthermore, the upper surface of the lid 57 of the item storage section 53 is positioned so as to be located at a position higher than the top surface 512, and is set to a size and height sufficient to accommodate the forearm (from elbow to wrist) of a front seat occupant (occupant sitting in the front seats 27, 28).

[0073] In addition, the front seat center console unit 50 of this embodiment not only includes the shift lever 52, but also an operation unit (not shown) that accepts operations related to various settings of the vehicle V, such as operation of a navigation system, and a support bracket that supports shift operation mechanisms such as the shift lever 52.

[0074] As shown in FIG. 5, the front seat center console portion 50 is a console with a rear vent for rear seat passengers, and a rear seat air outlet 60 for rear seat passengers (passengers seated in the rear seats 30, 31) is formed in the rear surface portion 513 of the cover member 51 described above.

[0075] As shown in FIG. 7, the rear surface 513 is positioned rearward of the item storage section 53 and at approximately the same height as the top surface 512, and the rear seat air outlet 60 provided in the center of the rear surface 513 when viewed from the front is formed as an inclined surface that slopes downward and backward so as to face the head and chest of the rear seat occupant. The rear seat air outlet 60 is provided with louvers that enable rear seat passengers to manually open and close the rear seat air outlet 60 and change the airflow direction.

[0076] As shown in FIG. 6, an air conditioning unit 100 (air conditioner) and a front seat supply duct 101 for supplying temperature-controlled air (cool air / warm air) from the air conditioning unit 100 to a front seat outlet (not shown) provided on the dashboard are provided inside the instrument panel 7 at the front side of the passenger compartment 2.

[0077] The rear seat supply duct 62 is connected to the upstream side of the air flow of the front seat supply duct 101, and a portion of the temperature-controlled air flowing from the air conditioning unit 100 through the front seat supply duct 101 to the front seat outlet (not shown) is branched into the rear seat supply duct 62.

[0078] The rear seat supply duct 62 is disposed (extends) so as to penetrate the interior of the front seat center console portion 50 in the front-rear direction, and a rear end portion (66b) is connected to the rear seat outlet 60 provided on the rear surface portion 513 of the front seat center console portion 50. A rear blower 102 is disposed in the rear seat supply duct 62 near the connection portion with the front seat supply duct 101, i.e., in the upstream portion of the air flow.

[0079] When the air conditioning unit 100 is operating, a portion of the temperature-controlled air is blown out from the front seat outlet (not shown), and the remainder is sent to the rear seat supply duct 62 side and then pressurized by the rear blower 102 through the rear seat supply duct 62 to the rear seat outlet 60 side.

[0080] Next, the routing of the rear seat supply duct 62 will be described in detail. 6, 7, and 9, the rear seat supply duct 62 has a rear routing portion 63, a vehicle width outer routing portion 64, an upper routing portion 65, and an upper rear routing portion 66, in this order from the upstream side to the downstream side in the air flow direction. Of these routing portions 63, 64, 65, and 66, each of the routing portions other than the rear routing portion 63 is provided in a pair on the left and right.

[0081] The rear routing portion 63 is routed rearward from the connection portion with the front seat supply duct 101 along the upper surface portion 22u of the tunnel portion 22. As shown in Fig. 7 and Fig. 9, the rear portion of the rear routing portion 63 is routed rearward from the front of the front wall 533 of the item storage portion 53 to directly below the bottom wall 531 of the item storage portion, that is, to slip between the bottom wall 531 and the upper surface portion 22u of the tunnel portion 22.

[0082] 7 and 9, the rear portion of the rear routing portion 63 that is recessed immediately below the bottom wall 531 of the article storage portion 53 is disposed approximately horizontally rearward in the middle of the article storage portion in the vehicle width direction up to a position just forward of the rear wall 534 (see FIG. 7) of the article storage portion 53. That is, the rear end portion 63a of the rear routing portion 63 is located immediately below the bottom wall 531 of the article storage portion 53.

[0083] 9 and 10, the pair of left and right vehicle width outer wiring portions 64 extend substantially horizontally from the rear end portion 63a of the rear wiring portion 63 to both left and right outer sides in a direction that coincides with the vehicle width direction, and the vehicle width direction inner end portions of both of them are connected in communication with the rear end portion 63a of the rear wiring portion 63. As a result, the rear seat supply duct 62 branches out to the left and right sides directly below the bottom wall 531 of the item storage portion 53.

[0084] That is, the pair of left and right vehicle width outside routing portions 64 are routed in opposite vehicle width directions from the rear end portion 63a of the rear routing portion 63. The vehicle width outside end portions 64b of the left and right vehicle width outside routing portions 64 are located in the space S between the side portion 511 of the front seat center console portion 50 and the side wall 532 of the item storage portion 53 on each of the left and right sides of the item storage portion 53.

[0085] The upper routing portion 65 is routed vertically upward along the side wall 532 of the item storage portion 53 in the space S between the side surface portion 511 of the front seat center console portion 50 and the side wall 532 of the item storage portion 53, the space being located on both the left and right outer sides of the item storage portion 53. Furthermore, the lower end portion 65a of the upper routing portion 65 is connected in communication with the vehicle width outer end portions 64b of the left and right vehicle width outer routing portions 64, and is routed upward up to a height equivalent to the rear seat air outlet 60, as shown in Figs.

[0086] Here, as shown in FIG. 10, at the rear of the front seat center console portion 50, directly below the left and right side edges 156 of the opening 56 that opens upward in the item storage portion 53, there exists a space S as dead space between the side surface portion 511 of the front seat center console portion 50 and the side wall 532 of the item storage portion 53. In this embodiment, the pivot parts 58 that pivotally mount the divided lid 571 so as to be able to open and close are provided on the left and right side parts 156 of the opening 56 of the front seat center console part 50, as described above. Therefore, the space S between the side surface part 511 of the front seat center console part 50 and the side wall 532 of the item storage part 53, which is located directly below the left and right side parts 156, is formed wider than in a configuration in which the pivot parts 58 are not provided on the left and right side parts 156 of the opening 56.

[0087] In this embodiment, as described above, the upper routing section 65 is arranged over the entire vertical length of the space S between the side portion 511 of the front seat center console section 50 and the side wall 532 of the item storage section 53, thereby making effective use of the space S, i.e., a wide dead space (wasted space) (see Figure 10).

[0088] In addition, the upper routing portion 65 is not limited to being routed vertically upward as in this example (see Figures 7 and 9), but may also be routed along the side wall 532 of the item storage section 53, slanting toward the rear as it moves upward in a side view of the vehicle V, although this is not shown in the figure. In any case, the upper routing portion 65 is located forward of the rear wall 534 of the item storage section 53 over the entire vertical length, including the upper end portion 65b (see Figure 9).

[0089] 7, the upper routing sections 65 are routed forward of the front end section 44F of the second driving battery case 44, which is located rearward of the rear wall 534 of the item storage section 53. Therefore, the second driving battery 42 does not have the upper routing sections 65 arranged on both sides of the front end section 44F, so the length in the vehicle width direction is not restricted by the pair of left and right upper routing sections 65, and the battery capacity can be ensured.

[0090] The pair of left and right upper rear routing portions 66 are routed in the front-rear direction at a height equivalent to the rear seat air outlet 60, in other words, above the upper surface portion 44u of the front end portion 44F of the second driving battery case 44. As shown in Fig. 9, the front end portion 66a of the upper rear routing portions 66 is connected in communication with the upper end portion 65b of the upper routing portion 65 described above.

[0091] The upper rear routing portion 66 is routed approximately horizontally in the rear direction from the upper end portion 65b of the upper routing portion 65 to the rear seat outlet 60 which is located rearward of the rear wall 534 of the item storage section 53, and the rear end portion 66b is connected in communication with the rear seat outlet 60. The left and right upper rear routing sections 66 are routed with their rear portions routed inward in the vehicle width direction behind the rear wall 534 of the item storage section 53 and in front of the rear seat air outlet 60, and their respective rear end portions 66b (inner end portions in the vehicle width direction) may be connected separately to the rear seat air outlet 60, or the left and right sides may be connected in a state where they merge with each other.

[0092] 7, as described above, the second driving battery case 44 extends forward beyond the rear end 50r of the front seat center console portion 50 so that the front end 44F is fitted inside the front seat center console portion 50, and the panel-like rear surface portion 513 in which the rear seat outlet 60 is provided is disposed above the upper surface portion 44u of the front end 44F of the second driving battery case 44. The rear end (66b) of the rear seat supply duct 62 connected to the rear seat outlet 60, i.e., the rear end 66b of the upper rear routing portion 66, is supported directly below by the front end 44F of the second driving battery case 44 (not shown).

[0093] Specifically, the rear end portion 66b of the upper rear routing portion 66 connected to the rear seat air outlet 60 is attached and fixed to the upper surface portion 44u of the front end portion 44F of the second driving battery case 44 via a bracket or the like (not shown).

[0094] (Attachment member 67 between item storage section 53 and second driving battery case 44) 7, 11, and 13, the attachment member 67 supporting the item storage portion 53 is provided inside the front seat center console portion 50, between the bottom wall 531 (see FIG. 13) of the item storage portion 53 and the upper surface portion 22u of the tunnel portion 22. That is, the item storage portion 53 is supported by the upper surface portion 22u of the tunnel portion 22 via the attachment member 67.

[0095] 7 and 11 to 13, the front end 44F of the second driving battery case 44 extends forward until it is located near the rear of the rear wall 534 of the item storage section 53. Furthermore, the attachment member 67 that supports the item storage section 53 also serves as an attachment member that supports the front end 44F of the second driving battery case 44. That is, the item storage section 53 of the front seat center console section 50 and the front end section 44F of the second driving battery case 44 are attached to the upper surface section 22u of the tunnel section 22 via a common attachment member 67.

[0096] Specifically, as shown in Figures 11 to 13, the mounting member 67 is a steel plate member integrally formed with a generally hat-shaped cross section and including a support portion 671 extending in the vehicle width direction along the upper surface 22u of the tunnel portion 22 so as to be able to accommodate the rear portion of the bottom wall 531 of the item storage section 53 and the front end portion 44F of the second driving battery case 44, left and right leg portions 672 extending downward from both left and right ends of the support portion 671 in the vehicle width direction, and left and right flange portions 673 extending outward in the vehicle width direction from the outer ends of the legs 672 to be able to be installed on both sides of the upper surface 22u of the tunnel portion 22. As shown in FIG. 13, for example, bolt insertion holes 671a are formed on both sides of the support portion 671 of the mounting member 67, and bolt insertion holes 673a are formed in the left and right flange portions 673, each penetrating in the up-down direction.

[0097] As shown in Figures 11 to 13, the front end 44F of the second driving battery case 44 is provided with flange portions 144 extending forward from both the left and right sides of the lower end, and a bolt insertion hole 144a is formed vertically through each tip (front end) of the pair of left and right flange portions 144, as shown in Figure 13.

[0098] As shown in Figs. 11 to 13, a box support bracket 68 is provided below the item storage section 53 and above the mounting member 67. The box support bracket 68 supports at least a rear portion in the front-rear direction of the bottom wall 531 of the item storage section 53 and includes a bottom wall reinforcing portion 681 (see Figs. 11 and 13) joined to the lower surface of the bottom wall 531 so as to be reinforced, a pair of left and right support legs 682 extending downward from both the left and right sides of the bottom wall reinforcing portion 681, and left and right flange portions 683 extending outward in the vehicle width direction from lower ends of the support legs 682. As shown in Fig. 13, a bolt insertion hole 683a is formed to penetrate in the up-down direction at the tip portions of the pair of left and right flange portions 683 of the box support bracket 68.

[0099] The flange portion 673 of the mounting member 67 described above is installed with the bolt insertion holes 673a, 22a (see FIG. 13) communicating in the up-down direction on each of the left and right sides of the upper surface portion 22u of the tunnel portion 22 facing the flange portion 673. The flange portion 673 and the upper surface portion 22u facing the flange portion 673 are fastened and fixed on each of the left and right sides using bolts B1 and nuts N1 inserted through the bolt insertion holes 673a, 22a.

[0100] Furthermore, the flange portion 144 provided on the front end portion 44F of the second driving battery case 44 and the flange portion 683 provided on the box support bracket 68 are installed in this order from above, with the bolt insertion holes 144a, 683a, 671a formed therein respectively communicating in the vertical direction with respect to the left and right sides of the support portion 671 of the mounting member 67. These flange portions 144, 683 are fastened together on both the left and right sides of the support portion 671 of the mounting member 67 by using bolts B2 and nuts N2 which communicate with the bolt insertion holes 144a, 683a, 671a.

[0101] Although the mounting member 67 is provided immediately below the item storage section 53, the present invention is not limited to this and may be provided immediately below the front end portion 44F of the second driving battery case 44. In either case, the front end 44F of the second driving battery case 44 can be extended from rear to front so as to be closer to the rear wall 534 of the item storage section 53 than when the mounting member 67 is installed between the rear wall 534 of the item storage section 53 and the front surface of the front end 44F of the second driving battery case 44, thereby ensuring the battery capacity of the second driving battery 42.

[0102] (Rear seat center console 70) As shown in Figures 1, 5 and 6, the rear seat center console portion 70 described above is erected from the rear seat cushion panel 131, and is provided with a cover member 71, which is an interior member mainly made of resin, comprising a top surface portion 711 forming the upper surface, and a pair of left and right side portions 712 (only the left side is shown) extending downward from both the left and right ends of the upper end, both of which are decorative panels.

[0103] The above-mentioned second driving battery case 44 is accommodated inside the rear seat center console portion 70 defined by the top surface portion 711 and the left and right side surface portions 712. In other words, the second driving battery case 44 is provided inside the rear seat center console portion 70 over approximately its entire length in the fore-and-aft direction, and functions as a skeletal member of the rear seat center console portion 70 to reinforce the rear seat center console portion 70.

[0104] For this reason, the top surface 711 and the left and right side surface portions 712 of the rear seat center console portion 70 may be supported by the rear seat cushion panel 131 via a bracket (not shown) provided inside the rear seat center console portion 70, or may be appropriately attached and fixed to the second driving battery case 44 (not shown). Specifically, the top surface 711 of the rear seat center console portion 70 disposed directly above the second driving battery case 44 may be supported by the second driving battery case 44.

[0105] As shown in Figs. 1, 5 and 6, the rear seat center console portion 70 is provided continuous with the front seat center console portion 50 in the front-rear direction at the middle portion of the passenger compartment 2 in the vehicle width direction. In detail, as shown in Figures 5 and 6, the front end of the top surface 711 of the rear seat center console unit 70 and the lower end of the rear surface 513 provided on the rear seat air outlet 60 of the front seat center console unit 50 are connected by engaging with each other, and similarly, the front end of the right side surface portion (not shown) of the rear seat center console unit 70 and the rear end of the right side surface portion 511 (see Figure 10) of the front seat center console unit 50 are connected (not shown), and the front end of the left side surface portion 712 of the rear seat center console unit 70 and the rear end of the left side surface portion 511 of the front seat center console unit 50 are connected. The left and right side surfaces 511 of the front seat center console portion 50 and the left and right side surfaces 712 of the rear seat center console portion 70 are connected to each other at their boundaries so as to be substantially flush in the front-rear direction.

[0106] In other words, the rear seat center console portion 70 comprises a rear seat center console rear portion 72 that is positioned above the rear seat cushion panel 131 in the fore-and-aft direction, and a rear seat center console front portion 73 that extends forward of the kick-up portion 12. Furthermore, the rear seat center console front portion 73, like the rear seat center console rear portion 72, is provided with an upper portion 74 which has the second driving battery case 44 inside, and a lower portion 75 which is located directly below the upper portion 74 and the second driving battery case 44 but does not have the second driving battery case 44 inside.

[0107] The above-mentioned top surface portion 711 and left and right side surface portions 712 (only the left side is shown) of the rear seat center console portion 70 are formed across the rear seat center console rear portion 72 and the rear seat center console front portion 73 (upper portion 74 and lower portion 75).

[0108] Further, the lower portion 75, which does not have the second driving battery case 44 inside, is provided with an opening 76 (through hole) that penetrates in the vehicle width direction. The opening 76 ensures ventilation in the width direction of the vehicle in the foot spaces of the left and right rear seat passengers, and is an exterior design that allows the rear seat passengers to feel a sense of openness.

[0109] In other words, by providing an opening 76 in the lower portion 75 which corresponds to the height of the feet of the rear seat passengers, the independence of the rear seats 30, 31 obtained by separating the left and right rear seats 30, 31 with the rear seat center console portion 70 can be maintained, while preventing the rear seat passengers from feeling oppressed and increasing comfort.

[0110] In addition, decorative panels (not shown) are provided on the inner surfaces of the opening 76 in the lower portion 75, which is formed in a cylindrical shape extending in the vehicle width direction, i.e., the upper inner surface, lower inner surface, front inner surface and rear inner surface, to ensure the external design of the inner surface of the opening 76.

[0111] The size, location, number, and other aspects of the openings 76 are not limited to those in this embodiment. For example, the openings 76 are provided in the center of the lower portion 75 in a front view (i.e., a side view of the vehicle V), but at least a portion of the periphery of the openings 76, such as the front edge, rear edge, or lower edge, may not be provided, and the openings 76 may be formed in the entire lower portion 75, or a plurality of openings may be disposed in the lower portion 75. Furthermore, the upper portion 74 and the lower portion 75 may be spaced apart in the vertical direction, and the openings 76 may be provided between them.

[0112] In addition, the thickness of the lower portion 75 in the vehicle width direction is not limited to the thickness corresponding to the second driving battery case 44, and the left and right side portions 712 (only the left side is shown) that form the lower portion 75 may be arranged so that the distance between these left and right side portions 712 in the vehicle width direction is narrower than the length of the second driving battery case 44 in the vehicle width direction.

[0113] (Top surface 711 of rear seat center console 70) As shown in Figures 1, 5, and 7, the top surface 711 of the rear seat center console portion 70 is provided with a shallow tray 77 on which items such as a mobile terminal can be placed, and a raised portion 80 that protrudes upward in front of the tray 77.

[0114] As shown in FIG. 5, the tray 77 has a bottom surface portion 78 that is horizontal in the vehicle width direction, and left and right vertical wall portions 79 that rise from both left and right edges of the bottom surface portion 78 and extend continuously at the same height along the side edges in the fore-and-aft direction, and is formed with a concave cross section that opens upward.

[0115] As shown in FIG. 8, the tray 77 serves as an intermediate backrest support portion on which the intermediate backrest portion 32 can be placed, extends in the fore-and-aft direction by a length equivalent to the fore-and-aft direction of the intermediate backrest portion 32 when tilted forward, and has a length in the vehicle width direction that is approximately the same as the length of the intermediate backrest portion 32 in the vehicle width direction.

[0116] The raised portion 80 is raised above the upper ends of the left and right vertical wall portions 79 of the tray 77. The upper surface of the raised portion 80 includes a raised upper surface rear portion 81 that extends forward from the front end of the tray 77 and is inclined so as to be positioned higher toward the front, and a raised upper surface front portion 82 that extends forward from the front end of the raised upper surface rear portion 81 and is gently inclined downward toward the front.

[0117] 5, the bottom surface portion 78 of the tray 77 is formed horizontally except for the front region, and the front region of the bottom surface portion 78 is formed sloping forward and upward from the front end of the rear horizontal portion to the height of the vertical wall portion 79. The raised upper surface rear portion 81 of the raised portion 80 is formed sloping forward and upward from the front end of the bottom surface portion 78 so as to be continuous with the front region of the bottom surface portion 78 of the tray 77 and to face the rear seat occupant in a side view of the vehicle V.

[0118] In addition, the raised upper surface rear portion 81 of the raised portion 80 is provided in an area within reach of the rear seat passengers, and is formed as a functional panel surface having at least one of an input function for the rear seat passengers to input various information and an output function for outputting information to the rear seat passengers.

[0119] Specifically, the output function is a display (display unit) or an audio output unit such as a speaker, etc. When the output function is a display, the display is disposed so that the entire image displayed on the display can be seen by the rear seat passengers.

[0120] The display is a device that projects an image by emitting light from a screen, and various displays can be used, such as a liquid crystal display, an organic electroluminescence display, etc. The display may be equipped with a touch panel that can be operated by a passenger by touching it.

[0121] The input function includes an operation input unit and a socket (connection terminal) for operating various on-board electronic devices such as audio equipment and rear seat heaters. The operation input unit includes a push button, a dial, a joystick, etc., and the socket includes a USB socket, an AC socket, and a DC socket, but there is no particular limit to the number or type of these operation input units and sockets.

[0122] As shown in FIG. 5, in this embodiment, the raised upper surface rear portion 81 serving as a functional panel surface is provided with an operation input unit 83 for audio equipment, rear seat heaters, etc., two USB sockets 84, and an AC socket 85.

[0123] Also, as shown in FIG. 8, the above-mentioned raised upper surface rear portion 81 of the raised portion 80 rises up to a height approximately equal to the vertical thickness of the front portion of the forward-tilted intermediate backrest portion 32, in line with the side view shape of the vehicle V at the front portion of the forward-tilted intermediate backrest portion 32, on the top surface portion 711 of the rear seat center console portion 70.

[0124] The top surface 711 of the rear seat center console portion 70 of this embodiment smoothly rises upward from the front region of the bottom surface portion 78 of the tray 77 to the raised upper surface rear portion 81 toward the front. As a result, as shown in FIG. 8, when the intermediate backrest portion 32 is tilted forward, its front portion faces the rear portion 81 of the raised portion 80 from near the rear, thereby protecting the rear portion 81 from external factors such as external forces.

[0125] Furthermore, as described above, when the intermediate backrest portion 32 is in the forward-tilted position, it is supported approximately horizontally by at least the tray 77 on the top surface 711 of the rear seat center console portion 70, and the upper surface portion 32u is flush with the upper surfaces 30Bu, 31Bu of the seat backs 30B, 31B of the left and right forward-tilted rear seats 30, 31 in the vehicle width direction (see FIG. 4), and is also flush with the upper surface 43u of the first driving battery case 43 in the front-rear direction (see FIGS. 4 and 8).

[0126] 1, 5, 6 and 8, the raised upper surface front portion 82 of the raised portion 80 is formed to gently incline in a front-down direction from the front end of the raised upper surface rear portion 81 until its front end is located near the lower edge of the rear seat air outlet 60, i.e., at the lower edge of the rear surface portion 513. This allows the wind blown out from the rear seat air outlet 60 to flow toward the rear seat occupants without being obstructed by the raised portion 80.

[0127] Furthermore, as shown in Figs. 4 and 8, the above-mentioned raised upper surface front portion 82 of the raised portion 80 is provided so as to be substantially flush with the upper surface portion 32u of the intermediate backrest portion 32 when tilted forward in the front-rear direction. As a result, the raised upper surface front portion 82 of the raised portion 80 can also be formed as part of the flat expanded luggage compartment floor surface 2Fa described above.

[0128] As shown in FIG. 1, the vehicle V of the present embodiment described above has a vehicle interior structure including a floor panel 1 forming a floor surface of the vehicle interior 2, seat cushions 30C, 31C of the rear seats 30, 31 arranged separately on the left and right above the floor panel 1, seat backs 30B, 31B of the rear seats 30, 31 arranged separately on the left and right sides so as to be able to be folded forward from above on the sides of the seat cushions 30C, 31C of the rear seats 30, 31, and a first driving battery case 43 arranged above a luggage compartment floor panel 132 forming the floor surface (bottom surface) of the luggage compartment 2a behind the seat cushions 30C, 31C on the floor panel 1, and a second driving battery case 44 arranged above the floor panel 1 between the left and right seat cushions 30C, 31C, a rear seat center console portion 70 (console) covering an upper surface portion 44u and left and right side portions of the second driving battery case 44, and ... 7, the intermediate backrest portion 32 is pivotally supported at its lower portion and can be tilted forward from above toward the rear seat center console portion 70, and is disposed between the seat backs 30B, 31B of the left and right rear seats 30, 31. As shown in FIG. 7, the front-to-rear thickness (L32) of the intermediate backrest portion 32 in an upright state is set to be smaller than the front-to-rear thickness (for example, L30B) of the seat backs 30B, 31B of the left and right rear seats 30, 31. As shown in FIG. The front end 43f of the driving battery case 43 is arranged close to the rear end portions 30Br, 31Br of the seat backs 30B, 31B of the rear seats 30, 31 in the forward-tilted state, and the seat backs 30B, 31B of the left and right rear seats 30, 31 in the forward-tilted state and the upper surface portions 30Bu, 31Bu, 32u of the intermediate backrest portion 32 are flush with each other in the vehicle width direction and form an expanded luggage compartment floor surface 2Fa together with the upper surface portion 43u of the first driving battery case 43.

[0129] According to the above configuration, the height of the flat expanded luggage compartment floor surface 2Fa formed by tilting forward all of the seat backs 30B, 31B and the intermediate backrest portion 32 of the left and right rear seats 30, 31 can be kept low without compromising the battery capacity, and the floor area of ​​the luggage compartment 2a can be expanded.

[0130] Specifically, by providing not only the first drive battery case 43 above the floor panel 1 but also the second drive battery case 44 disposed between the left and right seat cushions 30C and 31C, the battery capacity can be ensured.

[0131] Furthermore, as shown in FIG. 8, the front end portion 43f of the first drive battery case 43 is disposed close to the rear end portions 30Br and 31Br of the seat backs 30B and 31B of the rear seats 30 and 31 in the forward-falling state, and the second drive battery case 44 is disposed between the left and right seat cushions 30C and 31C of the rear seats 30 and 31. Thus, in a state where all of the seat backs 30B and 31B of the left and right rear seats 30 and 31 and the middle backrest portion 32 are in the forward-falling state, a substantially flat (fully flat) enlarged luggage compartment floor surface 2Fa can be formed.

[0132] And, by disposing the second drive battery case 44 disposed above the floor panel 1 between the left and right seat cushions 30C and 31C of the rear seats 30 and 31 in this way, for example, compared with the case of disposing it below the left and right seat cushions 30C and 31C of the rear seats 30 and 31, the height of the upper surface portions 30Bu and 31Bu of the left and right seat backs 30B and 31B in the forward-falling state can be suppressed to be low.

[0133] On the other hand, between the left and right seat cushions 30C and 31C of the rear seats 30 and 31, the second drive battery case 44 is disposed, but the front-rear thickness of the middle backrest portion 32 in the upright state is set to be smaller than the front-rear thickness of the seat backs 30B and 31B of the left and right rear seats 30 and 31 (L32 < L30B (see FIG. 7)). Thus, the height between the left and right rear seats 30 and 31 when the middle backrest portion 32 is in the forward-falling state can be suppressed to be low.

[0134] Therefore, without impairing the battery capacity, the height of the flat enlarged luggage compartment floor surface 2Fa in a state where all of the seat backs 30B and 31B of the left and right rear seats 30 and 31 and the middle backrest portion 32 are in the forward-falling state can be suppressed to be low, and the floor area of the luggage compartment 2a can be enlarged.

[0135] In one embodiment of the invention, as shown in FIG. 2, the floor panel 1 has a front floor panel 11 having a tunnel portion 22 extending fore and aft, a kick-up portion 12 rising from the rear end of the front floor panel 11, and a rear seat cushion panel 131 extending rearward from the upper end of the kick-up portion 12 and on which the seat cushions 30C, 31C of the rear seats 30, 31 are mounted, and the second driving battery case 44 is positioned above the rear seat cushion panel 131 and extends forward of the kick-up portion 12 above the tunnel portion 22.

[0136] According to the above configuration, the second driving battery case 44 is extended forward from the kick-up portion 12, so that the battery capacity can be ensured while the height between the seat cushions 30C, 31C of the left and right rear seats 30, 31 can be kept low.

[0137] In one embodiment of the invention, as shown in FIG. 5, the top surface 711 of the rear seat center console portion 70 has a tray 77 extending in the fore-and-aft direction as an intermediate backrest placement portion onto which the folded-down intermediate backrest portion 32 can be placed, and a raised portion 80 which is raised higher than the tray 77 in front of the tray 77, and the surface of the raised portion 80 which faces the rear seat occupant in a side view of the vehicle V, i.e., the raised upper surface rear portion 81, is provided with a functional surface which rises along the shape of the front part of the folded-down intermediate backrest portion 32 on the top surface 711 of the rear seat center console portion 70 in a side view of the vehicle V.

[0138] According to the above-described configuration, as shown in FIG. 5, the front portion of the folded-down intermediate backrest portion 32 substantially abuts or is close from the rear side to the raised upper surface rear portion 81, which serves as a functional surface, so that the functional surface of the rear seat center console portion 70 can be protected by the front portion of the folded-down intermediate backrest portion 32. Furthermore, the tray 77 can firmly support the intermediate backrest portion 32 when it is placed on it and tilted forward.

[0139] In one embodiment of the present invention, as shown in FIG. 8, the raised portion 80 and the folded-down intermediate backrest portion 32 are provided so that the raised upper surface front portion 82 and the upper surface portion 32u are substantially flush in the front-rear direction. According to the above-described configuration, the step between the raised portion 80 and the forward-tilted intermediate backrest portion 32 is eliminated, which contributes to a flat floor surface of the luggage compartment 2a.

[0140] The present invention is not limited to the configurations of the above-described embodiments, and many other embodiments can be obtained. For example, the rear seat center console portion of the present invention is not limited to the configuration of the rear seat center console portion 70 described above, and may have other configurations. FIG. 14 is an enlarged side view of a vehicle V equipped with a rear seat center console portion 70A of the first modified example of the rear seat center console portion 70 described above, the portion corresponding to the main portion of FIG.

[0141] 14, the rear seat center console portion 70A of the first modified example includes a cover member 71A that covers the second driving battery case 44, and a movable rear seat center console 90A and a swing arm 91 that are installed (placed) on a flat top surface portion 711A that forms the upper surface of the cover member 71A. Note that the intermediate backrest portion 32A is configured without being divided into an intermediate backrest main body portion 33 and a rear seat armrest 34.

[0142] The movable rear seat center console 90A extends in the front-rear direction so that its rear end is located at the rear end of the second driving battery case 44 and its front end is located forward of the front end of the rear seat cushion panel 131, and its lower surface over its entire front-rear direction length is installed on the upper surface 44u of the second driving battery case 44 via the top surface 711A of the cover member 71A. The top surface 711A of the cover member 71A is supported directly below by the upper surface 44u of the second driving battery case 44.

[0143] The front portion of the movable rear seat center console 90A is formed with a front end inclined surface portion 95 that is inclined downward and forward. The rear portion of the movable rear seat center console 90A is provided with an item storage portion 92 capable of storing items such as a tablet terminal, and a lid 93. The item storage portion 92 is formed in a bottomed rectangular tube shape having an opening portion 94 that opens upward.

[0144] The lid 93 is capable of closing the opening 94, and has a pair of left and right divided lids 931, 931 of a double-door type (double-door type) that opens the opening 94 from the center, similar to the lid 57 provided on the upper part of the item storage section 53 of the front seat center console section 50. Furthermore, the lid 93 has an upper surface portion on which a rear seat passenger can place their elbows so as to function as an armrest, similar to the lid 57 of the front seat center console section 50.

[0145] The swing arms 91 are formed linearly, and a pair of left and right swing arms 91 are provided on the front of the top surface 711A of the cover member 71A, both of which extend in the front-rear direction while placed on the top surface 711A of the cover member 71A.

[0146] Furthermore, the oscillating arm 91 is configured with a fixed pivot portion 91a whose front end is supported by an axis (pin) extending in the vehicle width direction on the upper surface 44u of the second driving battery case 44, and a movable pivot portion 91b whose rear end is supported by an axis (pin) extending in the vehicle width direction on the lower front end of the movable rear seat center console 90A.

[0147] As a result, the oscillating arm 91 is configured to support the rear seat center console section 70A so that it can swing between a placement position Pa where the rear seat center console section 70A is placed on the top surface 711A of the cover member 71A, and a forward flip-up position Pb where the rear seat center console section 70A is flipped up forward from the placement position Pa.

[0148] When the movable rear seat center console 90A moves from the placement position Pa to the front flip-up position Pb, the swing arm 91 rotates counterclockwise in the right side view of the vehicle V (as viewed from the state of FIG. 14) with the fixed pivot portion 91a as the rotation center.

[0149] Accordingly, the movable center console 90A for the rear seat rotates forward and upward so as to invert forward while moving away from the top surface portion 711A of the cover member 71A and the rear end becomes higher than the front end. At this time, the swing arm 91 is disposed so that the movable pivot portion 91b is located forward of the fixed pivot portion 91a. At the same time, the movable center console 90A for the rear seat rotates clockwise in the right side view of the vehicle V (as viewed from the state of FIG. 14) with the movable pivot portion 91b as the rotation center relative to the swing arm 91.

[0150] As a result, the movable rear seat center console 90A is installed at the front end of the top surface portion 711A at a position forward of the fixed pivot portion 91a in the forward flip-up position Pb, as shown by the virtual line in Figure 14, and is in an upright position tilted upward and rearward, and is positioned so that at least a portion of it fits into the space between the seat backs 27B, 28B of the left and right front seats 27, 28 from the rear. That is, since the space between the seat backs 27B, 28B of the left and right front seats 27, 28 can be blocked by the movable rear seat center console 90A, the independence of the rear seats 30, 31 can be improved.

[0151] Furthermore, when the movable rear seat center console 90A is in the forward flip-up position Pb, the front end inclined surface portion 95 abuts or faces closely to the rear portion 513 of the front seat center console portion 50, on which the rear seat air outlet 60 is provided, from the rear, thereby protecting the rear portion 513 from external factors.

[0152] Furthermore, when the movable rear seat center console 90A is placed in an upright position at the forward flip-up position Pb as described above, the intermediate backrest portion 32A can be tilted forward, so that the intermediate backrest portion 32A can be placed horizontally on the top surface portion 711A of the cover member 71A, as shown by the virtual line in Figure 14.

[0153] At that time, the front portion of the forward-tilted intermediate backrest portion 32A abuts from behind against the lower portion (front portion) of the movable rear seat center console 90A that stands up in the forward flip-up position Pb, thereby preventing the movable rear seat center console 90A from inadvertently falling backward.

[0154] Furthermore, in the rear seat center console portion 70A of the first modified example, the movable rear seat center console 90A is flipped forward and then the intermediate backrest portion 32A is tilted forward, so that the tilted intermediate backrest portion 32A can be directly installed on the top surface portion 711A of the cover member 71A without going through the movable rear seat center console 90A. In other words, the tilted intermediate backrest portion 32A can be installed in a position closer to the upper surface portion 44u of the second driving battery case 44.

[0155] This allows the second driving battery case 44, which is located below the folded-down intermediate backrest portion 32A, to be located higher while keeping the height of the upper surface portion 32Au of the folded-down intermediate backrest portion 32A low. Therefore, the height of the space above the folded-down intermediate backrest portion 32A in the vehicle interior 2 can be secured, and the battery capacity of the second driving battery 42 can be secured.

[0156] Furthermore, when the upper surface portion 32Au is set to a height at which the elbows of a rear seat passenger can be placed, the forward-tilted intermediate backrest portion 32A may be used as an armrest for the rear seat. In the forward-tilted state, the intermediate backrest portion 32A is supported by a top surface portion 711A of the rear seat center console portion 70A (cover member 71A) serving as an intermediate backrest support portion. On the other hand, the top surface portion 711A is supported from directly below by the top surface portion 44u so as to form a substantial upper surface portion of the second driving battery case 44. Therefore, the intermediate backrest portion 32A can function as an armrest for the rear seat, on which the elbows can be stably placed.

[0157] When the present invention is provided with a movable rear seat center console in the rear seat center console section, it may be provided with a long type movable rear seat center console 90B that is longer in the front-to-rear direction than the movable rear seat center console 90A of variant 1, such as the rear seat center console section 70B of variant 2 shown in Figure 15.

[0158] As shown in FIG. 15, a movable rear seat center console 90B of the second modified example does not include a swing arm 91, and is capable of swinging at its front end relative to a top surface 711A of a cover member 71A. More specifically, the movable center console 90B for a rear seat in the second modified example is provided with a fixed pivotal attachment part 98 at the front end part of the top surface part 711A of the cover member 71A. The fixed pivotal attachment part 98 supports the front end of the movable center console 90B for a rear seat in the mounting position Pa and the top surface part 711A facing the front end via a pivotal attachment shaft extending in the vehicle width direction.

[0159] Here, the movable rear seat center console 90A of the above-mentioned modified example 1 is shorter in the front-rear direction than the movable rear seat center console 90B of the modified example 2, as shown in Fig. 14, so that when it is raised in the front flip-up position Pb, it can be suppressed to a lower height than the movable rear seat center console 90B of the modified example 2. Therefore, the movable rear seat center console 90A of the modified example 1 closes the space between the seat backs 27B, 28B of the left and right front seats 27, 28 in the front flip-up position Pb, while relieving a feeling of oppression and claustrophobia. In contrast, the movable rear seat center console 90B of the modified example 2 can be raised at approximately the same height as the seat backs 27B, 28B of the front seats 27, 28 in the front flip-up position Pb, as shown in Fig. 15, so that the independence of the rear seats 30, 31 can be further improved.

[0160] As in the first modification, the rear seat center console portion 70B of the second modification may be configured so that the lower portion (front portion) of the movable rear seat center console 90B, which stands up in the forward flip-up position Pb, comes into contact with the front portion of the forward-tilted intermediate seat backrest portion 32A from behind, thereby preventing the movable rear seat center console 90B from inadvertently tipping rearward, as shown by the imaginary line in FIG. 15.

[0161] Furthermore, needless to say, in the rear seat center console portion 70B of variant 2, as in variant 1, the forward-tilted intermediate backrest portion 32A may be used as a rear seat armrest when the upper surface portion 32Au is set to a height at which the elbows of a rear seat passenger can be placed.

[0162] As described above in detail, the rear seat center console section 70A according to variant example 1 shown in FIG. 14 and the rear seat center console section 70B according to variant example 2 shown in FIG. 15 include a cover member 71A and movable rear seat center consoles 90A, 90B installed on a top surface 711A of the cover member 71A, and the movable rear seat center consoles 90A, 90B are configured to be able to be flipped up relative to the top surface 711A of the cover member 71A further forward than the forward tilt trajectory that causes the intermediate backrest portion 32A in an upright position to tilt forward onto the top surface 711A of the cover member 71A.

[0163] According to the above-mentioned configuration, when the intermediate backrest portion 32A is in the upright state, the rear seat passenger can use the movable rear seat center consoles 90A, 90B installed on the top surface portion 711A of the cover member 71A. That is, the rear seat passenger can use the item storage portion 92 provided in the movable rear seat center consoles 90A, 90B.

[0164] On the other hand, by flipping the movable rear seat center consoles 90A, 90B forward relative to the top surface 711A of the cover member 71A, the intermediate backrest portion 32A can be tilted forward while keeping the height of the upper surface 32Au of the intermediate backrest portion 32A low without interfering with the movable rear seat center consoles 90A, 90B when tilted forward.

[0165] In one embodiment of the present invention, when the folded-down intermediate backrest portion 32A is set to a height at which the rear seat passenger can place their elbows, the rear seat passenger can use the intermediate backrest portion 32A as a rear seat armrest. At that time, the folded-down intermediate backrest portion 32A is supported by the highly rigid second driving battery case 44 via the top surface portion 711A of the cover member 71A. Therefore, the intermediate backrest portion 32A can function as an armrest for the rear seat, on which the elbows can be stably placed.

[0166] In the above-described embodiment, the second driving battery case 44 disposed between the left and right rear seats 30, 31 is configured so that its front portion extends forward of the kick-up portion 12, but the present invention is not limited to this configuration, and the second driving battery case 44 may be configured so that its front portion does not extend forward of the kick-up portion 12.

[0167] Furthermore, in this embodiment, the second driving battery case 44 has its front portion extending horizontally forward from the kick-up portion 12 and positioned above and spaced apart from the upper surface portion 22u of the tunnel portion 22, but this is not limited to this and the second driving battery case 44 may be configured to be installed without being spaced apart from the upper surface portion 22u of the tunnel portion 22.

[0168] Furthermore, the floor panel 1 of this embodiment is equipped with a tunnel portion 22 that protrudes upward from the front floor panel 11, and a vertical wall-like kick-up portion 12 that rises upward from the rear end of the front floor panel 11, but the present invention is not limited to such floor panels, and may, for example, be equipped with a front floor panel that does not have the tunnel portion 22 or kick-up portion 12, but is formed entirely flat, such as the front floor panel of an electric vehicle. In other words, the first and second drive batteries 41, 42 may be configured to be installed on the upper surface of such a flat front floor panel.

[0169] Furthermore, the vehicle of the present invention may be any vehicle equipped with a drive battery, and may be a normal hybrid vehicle that does not support plug-in charging, or may be an electric vehicle or a fuel cell vehicle.

[0170] In the configuration of the present invention and the above-described embodiment, the rear seat backrest portion corresponds to the seat backs 30B and 31B. The rear seat cushions correspond to the seat cushions 30C and 31C of the rear seats 30 and 31. The floor surface of the luggage compartment behind the rear seat of the floor panel corresponds to the luggage compartment floor panel 132. The upper surface of the intermediate backrest portion that has been tilted forward corresponds to the upper surface 32u of the intermediate backrest portion 32. The console corresponds to the rear seat center console parts 70, 70A, and 70B. The upper surface of the console corresponds to the top surface 711 of the rear seat center console 70. The middle backrest placement area is compatible with Tray 77. The surface of the raised portion that faces the rear seat passenger in a side view of the vehicle corresponds to the raised upper surface rear portion 81, the upper surface of the raised portion corresponds to the raised upper surface front portion 82; The base portion corresponds to the cover member 71A, The top surface of the base portion corresponds to the top surface portion 711A. The movable consoles correspond to the movable rear seat center consoles 90A, 90B, but as described above, the present invention is not limited to the configurations of the above-mentioned embodiments.
