Abstract
Description
[Technical Field]
[0001] The present invention relates to a vehicle interior structure that includes, for example, a floor panel having a floor pan, a kick-up portion rising from the rear end of the floor pan, and a rear seat cushion pan extending rearward from the upper end of the kick-up portion, front seats installed separately on the left and right above the front part of the floor pan, a front seat center console portion positioned between the seat portions of the left and right front seats, and rear seats installed separately on the left and right above the rear seat cushion pan. [Background technology]
[0002] In vehicles such as hybrid vehicles and electric vehicles, a known vehicle interior configuration in which a drive battery is mounted above a floor panel is one in which the battery is laid out (placed) above the rear floor of the luggage compartment, as exemplified in Patent Document 1.
[0003] However, if the drive battery case attached to the drive battery is mounted above the rear floor of the luggage compartment while maintaining battery capacity, the floor of the luggage compartment becomes higher, resulting in a problem of insufficient effective height within the luggage compartment. This problem is particularly pronounced in style-oriented vehicles with low roof heights.
[0004] However, for example, in a configuration in which the drive battery case is positioned between the left and right rear seat cushions, if it is made bulky to ensure battery capacity, the height between the left and right rear seat cushions will be high, just like in the case of the luggage compartment floor.
[0005] Therefore, while extending the drive battery case between the left and right rear seat cushions further forward than the front ends of the left and right rear seat cushions is effective in reducing the height between the left and right rear seat cushions while ensuring sufficient battery capacity, it also raises the risk of dividing the foot space of the left and right rear seat passengers in the vehicle width direction.In that case, a drive battery case that extends further forward than the front ends of the left and right rear seat cushions could impede the airflow in the foot space of the left and right rear seat passengers, causing them to feel closed in or oppressed.

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-71759 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 can ensure the battery capacity of the drive battery case while achieving excellent exterior design, such as increasing the sense of openness around the feet of the rear seats, and can improve air circulation in the foot spaces of the left and right rear seats. [Means for solving the problem]
[0008] This invention is a vehicle interior structure comprising: a floor panel having a floor pan, a kick-up portion rising from the rear end of the floor pan, and a rear seat cushion pan extending rearward from the upper end of the kick-up portion; front seats installed separately on the left and right above the front part of the floor pan; a front seat center console portion located between the seating portions of the left and right front seats; and rear seats installed separately on the left and right above the rear seat cushion pan, wherein a drive battery case is located above the rear seat cushion pan between the seating portions of the left and right rear seats, the drive battery case is fixed to the rear seat cushion pan, and extends upward and apart from the floor pan toward the space forward of the kick-up portion, and the rear of the front seat center console portion and the front end of the drive battery case are attached to the floor pan via a common mounting member.
[0009] With this configuration, it is possible to ensure the battery capacity of the drive battery case while achieving an excellent exterior design, such as enhancing the sense of openness around the feet of the rear seats, and to improve the air circulation in the foot spaces of the left and right rear seats.
[0010] In one aspect of the present invention, the rear portion of the front seat center console portion and the front end portion of the drive battery case are fastened together to the mounting member by the same fastener.
[0011] According to this configuration, the mounting portion where the front seat center console portion and the drive battery case are mounted to the floor pan via the mounting members can be made more compact.
[0012] In another aspect of the present invention, the driving battery case extends forward from the rear end of the front seat center console portion and is attached via the mounting member forward of the rear end of the front seat center console portion.
[0013] According to the above configuration, the mounting portion is located forward of the rear end of the front seat center console portion, so the drive battery case can be extended forward of the rear end of the front seat center console portion, ensuring greater battery capacity compared to when the battery case is mounted on the floor pan behind the rear end of the seat center console.
[0014] Furthermore, by attaching the front end of the drive battery case further forward than the rear end of the center console for the front seats, the space that communicates in the vehicle width direction between the forward extension of the drive battery case and the floor pan can be made wider in the fore-and-aft direction.
[0015] In another aspect of the present invention, the rear of the front seat center console section is provided with an item storage section, and a rear seat air outlet is provided behind the item storage section of the front seat center console section and above the top surface of the drive battery case, and the front end of the drive battery case is positioned near the rear of the rear end of the item storage section, and the rear seat air outlet protrudes forward so as to be able to be supported from directly below.
[0016] According to the above configuration, the rear seat air outlet is supported by the drive battery case, which is spaced above the floor pan, so that it can be installed stably while ensuring a predetermined height facing the rear seat occupants. Furthermore, since the drive battery case can be extended forward up to the rear of the rear end of the item storage section, sufficient battery capacity can be ensured.
[0017] In another aspect of the present invention, a tunnel section is provided in the center of the floor pan in the vehicle width direction, extending along the fore-and-aft direction and bulging upward relative to the surrounding area, and the mounting member is fixed to the upper surface of the tunnel section so as to be able to support the rear of the front seat center console section and the front end of the drive battery case from below.
[0018] According to the above configuration, by fixing the mounting member to the upper surface of the tunnel portion, it is possible to firmly support the mounting member in a compact form in the vertical direction by utilizing the height of the highly rigid tunnel portion without having to form it bulky in the vertical direction.
[0019] In one embodiment of the present invention, a rear seat armrest is provided directly above the drive battery case. According to this configuration, by extending the drive battery case further forward as described above, it is possible to keep the height low while ensuring the battery capacity.
[0020] Therefore, even though the drive battery case is provided between the seat portions of the left and right rear seats, the rear seat armrest above the drive battery case can be set at an appropriate height where rear seat passengers can rest their elbows without interfering with the drive battery case or the rear seat console portion that covers the drive battery case.
[0021] In another aspect of the present invention, an intermediate backrest portion is provided between the backrest portions of the left and right rear seats, and the drive battery case is extended forward so as to be able to support the intermediate backrest portion from below when it is tilted forward.
[0022] With this configuration, the drive battery case can be extended further forward, as described above, to maintain the battery capacity while keeping the height low. Therefore, when the middle backrest is tilted forward so that it can be supported from below by the drive battery case, the vehicle interior height, i.e., the height between the tilted middle backrest and the vehicle interior ceiling, can be maintained. [Effects of the Invention]
[0023] With this configuration, it is possible to ensure the battery capacity of the drive battery case while achieving an excellent exterior design, such as enhancing the sense of openness around the feet of the rear seats, and to improve the air circulation in the foot spaces of the left and right rear seats.

[0025] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the figure, arrow F indicates the front of vehicle V, arrow U indicates the top of vehicle V, arrow Ri indicates the right side of vehicle V, and arrow Le indicates the left side of vehicle V. In the following explanation, "front," "rear," "right," "left," "up," and "down" indicate directions relative to vehicle V unless otherwise specified.
[0026] The vehicle V of this embodiment is a plug-in hybrid electric vehicle (PHEV), which is a hybrid vehicle that combines an internal combustion engine and an electric motor to obtain driving force, and which is capable of charging a power storage device from a commercial household power source.
[0027] (basic structure) As shown in Figures 1 to 6, particularly Figures 1, 5 and 6, the vehicle V of this embodiment mainly comprises a steel floor panel 1 that forms the floor surface (bottom surface) of the passenger compartment 2, a pair of left and right front seats 27, 28, and a pair of left and right rear seats 30, 31.
[0028] The floor panel 1 is integrally or integrally formed with a front floor panel 11 that supports a pair of left and right front seats 27, 28, a vertical wall-like kick-up portion 12 that rises upward from the rear end of the front floor panel 11, and a rear floor panel 13 that extends rearward from the kick-up portion 12.
[0029] The rear floor panel 13 is integrally or integrally formed with a rear seat cushion panel 131 (rear seat pan) that supports the seat cushions 30C, 31C of the rear seats 30, 31 described later, and a luggage compartment floor panel 132 that is connected to the rear seat cushion panel 131 so as to extend rearward and forms the floor surface of the luggage compartment 2a.
[0030] The trunk floor panel 132 has a recess 132a at the rear of the center of the trunk floor panel 132 in the vehicle width direction, which is stepped down so that a spare tire can be accommodated, and a rear end panel 14a (see FIG. 6) extending in the vehicle width direction is attached to the open rear end of the recess 132a. The floor panel 1 forms the floor surface of the passenger compartment 2 other than the trunk 2a (i.e., the floor surface of the passenger compartment in front of the trunk 2a) with the front floor panel 11, kick-up portion 12, and rear seat cushion panel 131.
[0031] 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.
[0032] 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 rearward and a rear gate 16 that covers the rear gate opening 15 in an openable and closable manner.
[0033] The rear gate 16 includes a rear gate inner panel 17, a rear gate outer panel 18, and a rear window 19, and of these, the rear gate inner panel 17 is covered from the passenger compartment 2 side by a rear gate trim 171 as an interior member.
[0034] The vehicle V is also provided with a roof panel 20 made of 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 portion.
[0035] Furthermore, as shown in Figures 1, 5, and 6, the above-mentioned front floor panel 11 has a tunnel portion 22 that extends 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 protrudes toward the inside of the passenger compartment 2.
[0036] This tunnel section 22 is the center of the vehicle body rigidity, and its rear end is joined to the kick-up section 12. The kick-up section 12 is formed in the shape of a vertical wall that is higher than the rear end of the tunnel section 22.
[0037] A plurality of cross members 23, 24 (vehicle body rigidity members) spaced apart in the front-to-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) serving as vehicle body rigidity members, and as shown in FIGS. 1 and 6, 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.
[0038] 1 and 6, a plurality of 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 below 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 of the rear floor panel 13 and the kick-up portion 12.
[0039] The intermediate rear cross member 26 (No. 4 cross member) faces the rear floor panel 13 on both the upper and lower 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 upper and lower sides and is also a hat-shaped cross section that opens upward.
[0040] 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.
[0041] 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 and supports the head of the occupant.
[0042] Similarly, as shown in Figures 1 and 5, of the pair of left and right front seats 27, 28, the passenger seat 28 (in this example, the front seat 28 on the left side of the vehicle) is equipped with a seat cushion 28C that forms the seating surface for the occupant, a seat back 28B that extends upward from the rear end of the seat cushion 28C to form the 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.
[0043] 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.
[0044] 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 are equipped with seat cushions 30C, 31C that form a seating surface for the occupant, seat backs 30B, 31B that extend upward from the rear end of the seat cushions 30C, 31C and form a backrest surface for the occupant, and headrests 30H, 31H that are provided on the upper part of the seat backs 30B, 31B and support the head of the occupant.
[0045] In addition, a rear seat center console portion 70 is provided between the left and right rear seats 30, 31, i.e., in the middle portion in the vehicle width direction, to separate the seat cushions 30C, 31C of the left and right rear seats 30, 31 in the vehicle width direction, and an intermediate backrest portion 32 is provided between the seat backs 30B, 31B of the left and right rear seats 30, 31, i.e., in the middle portion in the vehicle width direction.
[0046] The left and right rear seats 30, 31 are separated and partitioned in the vehicle width direction 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.
[0047] 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.
[0048] 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., tilted forward).
[0049] Incidentally, each seat back 30B, 30B of the pair of left and right rear seats 30, 31 described above is configured to be able to move forward as shown in Figure 4 via a fulcrum 37 (seat back rotation fulcrum) (see Figure 6) provided independently of each other at the bottom.
[0050] Similarly, the intermediate backrest portion 32 is configured to be movable forward as shown in Figure 4 via another fulcrum 38 (seatback rotation fulcrum) (see Figure 6) located below the above-mentioned fulcrum 36 (armrest rotation fulcrum).
[0051] 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 using a bracket or the like.
[0052] 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.
[0053] (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.
[0054] Each of the first and second drive 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.
[0055] The batteries constituting the battery pack may be lead-acid batteries, lithium-ion batteries, or nickel-metal hydride batteries, or may be secondary batteries other than these. Furthermore, the battery installed in the vehicle V may not only be 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 surfaces 43u, 44u of both are formed in a horizontal, flat shape.
[0056] (first drive battery 41) As shown in FIGS. 1, 5, and 7, the first driving battery 41 is disposed in the space below the luggage compartment 2a located behind the left and right rear seats 30, 31. The battery case 43 of the first drive battery 41 (hereinafter referred to as the "first drive battery case 43") extends linearly in the vehicle width direction and is arranged 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 drive 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 downward bulging part in the rear part of the luggage compartment floor panel 132 is housed in the front part of a recess 132a that is used to store a spare tire.
[0057] As shown in Figure 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.
[0058] As shown in Figures 4 and 8, the first driving battery case 43 is positioned such that its front end 43f is close to the rear end 30Br, 31Br of the seat backs 30B, 31B in the forward-folded 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-folded state.
[0059] 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 front-to-rear direction with the upper surface portions 30Bu, 31Bu, 32u of the seat backs 30B, 31B and the intermediate backrest portion 32 of the left and right rear seats 30, 31 when they are folded forward. 1, 4, and 6, a luggage compartment partition board 40 that separates the rear of the luggage compartment 2a into upper and lower sections is removably and horizontally installed above the luggage compartment floor panel 132 and behind the rear end of the first drive battery case 43. The luggage compartment partition board 40 is positioned at a height such that the upper surface 40u is at approximately the same height as the upper surface 43u of the first drive battery case 43.
[0060] 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 of the luggage compartment floor panel 132 (see Figures 6 and 7).
[0061] Furthermore, as shown in Figures 4 and 8, when the seat backs 30B, 31B and intermediate backrest portions 32 of the left and right rear seats 30, 31 are folded 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.
[0062] That is, 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 become a flat expanded luggage compartment floor surface 2Fa capable of carrying a large amount of cargo, as shown in Figures 4 and 8.
[0063] Although not shown, the seatbacks 30B, 31B and the intermediate backrests 32 of the left and right rear seats 30, 31 can be folded forward independently, so it is not necessary to fold one of these seatbacks 30B, 31B, 32 forward. This allows for both occupants to sit in the rear seats 30, 31 without folding forward one of the seatbacks 30B, 31B, and expand the space of the luggage compartment 2a. The luggage compartment divider board 40 is not essential and may be omitted. Furthermore, the luggage compartment divider board 40 may extend forward so as to be installed from above on the upper surface 43u of the first drive battery case 43, with the forward extension of the luggage compartment divider board 40 essentially forming the upper surface (43u) of the first drive battery case 43.
[0064] (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 linearly in the front-to-rear 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.
[0065] 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 Figure 7, the rear end 44r of the second driving battery case 44 is located close to the front end 43f of the first driving battery case 43 in the middle in the vehicle width direction, and extends linearly forward.
[0066] 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 drive battery case 44 is configured by arranging multiple batteries in series in the front-to-rear direction to correspond to the second drive battery case 44, which extends in the front-to-rear direction. Therefore, by extending the second drive battery case 44 forward beyond the kick-up portion 12, the battery capacity of the second drive battery 42 is ensured.
[0067] 1, 2, 5, 7, and 8, particularly FIG. 8, the front end 44F of the second driving battery case 44 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 by the tunnel portion 22 inside the front seat center console portion 50 via a mounting member 67 (FIG. 7), which will be 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 (bridged) between the mounting member 67 and the rear seat cushion panel 131.
[0068] (Front seat center console 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 is connected near its front end to the lower part of the central part 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.

[0085] Specifically, as shown in Figures 9 to 11, the mounting member 67 is a steel plate member integrally formed with an approximately hat-shaped cross section and including a support portion 671 extending in the vehicle width direction along the upper surface portion 22u of the tunnel portion 22 so as to be able to install the rear portion of the bottom wall 531 of the item storage section 53 and the front end portion 44F of the second drive battery case 44, left and right leg portions 672 extending downward from both left and right end portions 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 leg portions 672 and able to be installed on both sides of the upper surface portion 22u of the tunnel portion 22. As shown in FIG. 11, 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 vertical direction.
[0086] As shown in Figures 9 to 11, the front end 44F of the second driving battery case 44 is provided with flange portions 144 that extend forward from both the left and right sides of the lower end, and bolt insertion holes 144a are formed in the vertical direction at each tip end (front end) of the pair of left and right flange portions 144, as shown in Figure 11.
[0087] 9 to 11, 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 the rear portion in the front-to-rear direction of the bottom wall 531 of the item storage section 53 and includes a bottom wall reinforcing portion 681 (see FIGS. 9 and 11) joined to the underside of the bottom wall 531 to provide reinforcement, 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 the lower end portions of the support legs 682. As shown in FIG. 11, bolt insertion holes 683a are formed to pass through 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.
[0088] The flange portion 673 of the mounting member 67 described above is installed with bolt insertion holes 673a, 22a (see FIG. 11) on each of the left and right sides communicating in the vertical direction with respect to 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.
[0089] 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 using bolts B2 and nuts N2 which communicate with the bolt insertion holes 144a, 683a, 671a.
[0090] Although the mounting member 67 is provided directly below the item storage section 53, the present invention is not limited to this and the mounting member 67 may be provided directly 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.
[0091] (Rear seat center console 70) As shown in Figures 1, 5, and 6, the rear seat center console section 70 described above is erected from the rear seat cushion panel 131 and comprises a cover member 71, which is an interior component made mainly of resin, and includes 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.
[0092] The second driving battery case 44 described above is housed inside the rear seat center console portion 70, which is 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.
[0093] For this reason, the top surface 711 and 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 brackets (not shown) provided inside the rear seat center console portion 70, or may be appropriately attached and fixed to the second drive battery case 44 (not shown). Specifically, the top surface 711 of the rear seat center console portion 70, which is disposed directly above the second drive battery case 44, may be supported by the second drive battery case 44.
[0094] As shown in Figures 1, 5 and 6, the rear seat center console section 70 is provided continuous with the front seat center console section 50 in the front-to-rear direction at the middle of the vehicle width direction of the passenger compartment 2. More specifically, 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 of the rear seat center console unit 70 and the rear end of the right side surface of the front seat center console unit 50 are connected (not shown), and the front end of the left side surface 712 of the rear seat center console unit 70 and the rear end of the left side surface 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 at their boundaries so as to be substantially flush in the front-to-rear direction.
[0095] 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 front part 73 of the rear seat center console, like the rear part 72 of the rear seat center console, is provided with an upper part 74 which has the second driving battery case 44 inside, and a lower part 75 which is located directly below the upper part 74 and the second driving battery case 44 and does not have the second driving battery case 44 inside.
[0096] 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).
[0097] Furthermore, the lower section 75 that 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.
[0098] That is, by providing an opening 76 in the lower portion 75 at the height corresponding to 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 the rear seat passengers do not feel oppressed and comfort can be increased.
[0099] In addition, decorative panels (not shown) are provided on the inner surfaces of the cylindrical opening 76 in the lower portion 75 that extends 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.
[0100] The size, location, number, and other aspects of the openings 76 are not limited to those of the present embodiment. For example, openings 76 are provided in the center of lower portion 75 when viewed from the front (i.e., when viewed from the side of vehicle V), but openings 76 may not be provided on at least a portion of the periphery, such as the front edge, rear edge, or lower edge, and may be formed over the entire lower portion 75, or multiple openings may be arranged in lower portion 75. Furthermore, openings 76 may be provided between upper portion 74 and lower portion 75, spaced apart in the vertical direction.
[0101] Furthermore, 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 positioned 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.
[0102] (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 section 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.
[0103] As shown in Figure 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 front-to-rear direction, and is formed with a concave cross section that opens upward.
[0104] As shown in Figure 8, the tray 77 serves as an intermediate backrest support portion on which the intermediate backrest portion 32 can be placed when it is folded forward, and extends in the front-to-rear direction by a length equivalent to the front-to-rear direction of the intermediate backrest portion 32 when folded 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.
[0105] 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 that it is 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 inclined gently downward toward the front.
[0106] 5, the bottom surface 78 of the tray 77 is formed horizontally except for its front region, and the front region of the bottom surface 78 is formed to be inclined in an upper-front direction 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 to be inclined in an upper-front direction from the front end of the bottom surface 78 so as to be continuous with the front region of the bottom surface 78 of the tray 77 and to face the rear seat occupant in a side view of the vehicle V.
[0107] 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.
[0108] 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, it is arranged so that the entire image displayed on the display can be seen by rear seat passengers.
[0109] The display is a device that projects an image by emitting light from the screen, and various displays can be used, such as a liquid crystal display, an organic EL display, etc. The display may be equipped with a touch panel that can be operated by the occupant by touching it.
[0110] The input function includes an operation input unit and a socket (connection terminal) for operating various electronic devices mounted on the vehicle, 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 the number and types of these operation input units and sockets are not particularly limited.
[0111] As shown in FIG. 5, in this embodiment, the rear portion 81 of the raised upper surface, which serves 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.
[0112] As shown in FIG. 8, the raised upper surface rear portion 81 of the raised portion 80 rises to a height approximately equal to the vertical thickness of the front portion of the forward-folded intermediate backrest portion 32, along the side view shape of the vehicle V at the front portion of the forward-folded intermediate backrest portion 32 on the top surface portion 711 of the rear seat center console portion 70.
[0113] The top surface 711 of the rear seat center console portion 70 of this embodiment rises smoothly upward from the front region of the bottom surface 78 of the tray 77 to the raised upper surface rear portion 81 toward the front. As a result, as shown in Figure 8, when the intermediate backrest portion 32 is folded forward, the front portion faces the rear portion 81 of the raised upper surface of the raised portion 80 from near the rear, thereby protecting the rear portion 81 of the raised upper surface from external factors such as external forces.
[0114] Furthermore, as described above, when the intermediate backrest portion 32 is folded forward, 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 surface portions 30Bu, 31Bu of the seat backs 30B, 31B of the left and right forward-folded rear seats 30, 31 in the vehicle width direction (see Figure 4), and is also flush with the upper surface portion 43u of the first driving battery case 43 in the front-to-rear direction (see Figures 4 and 8).
[0115] 1, 5, 6, and 8, the raised upper surface front portion 82 of the raised portion 80 is formed to be gently inclined downward and forward 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, that is, at the lower edge of the rear surface portion 513. As a result, the air blown out from the rear seat air outlet 60 is not obstructed by the raised portion 80 and can flow toward the rear seat occupants.
[0116] Furthermore, as shown in FIGS. 4 and 8, the 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.
[0117] As shown in FIG. 1, the vehicle V of the present embodiment described above has a vehicle interior structure including a floor panel 1 having a front floor panel 11 (floor pan), a kick-up portion 12 rising from the rear end of the front floor panel 11, and a rear seat cushion panel 131 (rear seat cushion pan) extending rearward from the upper end of the kick-up portion 12, front seats 27, 28 installed separately on the left and right above the front part of the front floor panel 11, a front seat center console portion 50 disposed between seat cushions 27C, 28C of the left and right front seats 27, 28, and rear seats 30, 31 installed separately on the left and right above the rear seat cushion panel 131. As shown in FIG. A second drive battery case 44 (drive battery case) is disposed above the cushion panel 131, between the seat cushions 30C, 31C of the left and right rear seats 30, 31. The second drive battery case 44 is fixed to the rear seat cushion panel 131 and, as shown in Figures 2 and 7, extends upward and away from the front floor panel 11 toward the space forward of the kick-up portion 12. As shown in Figures 7, 9 to 11, the item storage section 53 provided at the rear of the front seat center console section 50 and the front end portion 44F of the second drive battery case 44 are attached to the front floor panel 11 via a common mounting member 67.
[0118] According to the above configuration, it is possible to ensure the battery capacity of the second driving battery 42 equipped with the second driving battery case 44, while achieving an excellent exterior design, such as enhancing the sense of openness around the feet of the rear seats 30, 31, and also to improve the air circulation between the feet of the left and right rear seats 30, 31.
[0119] In detail, by attaching the front end portion 44F of the second driving battery case 44 to the front floor panel 11 via the mounting member 67, the second driving battery case 44, which extends forward in a cantilevered manner from the kick-up portion 12, can be efficiently supported from the front.
[0120] Furthermore, since the portion of the second driving battery case 44 that extends forward from the kick-up portion 12 is spaced upward relative to the front floor panel 11, as shown in Figures 1 and 7, a space that communicates in the vehicle width direction, i.e., an opening 76, can be provided between the forward extending portion of the second driving battery case 44 and the front floor panel 11.
[0121] This allows for an excellent exterior design, such as an increased sense of openness around the feet of the rear seats 30, 31, and also improves air circulation between the feet of the left and right rear seats 30, 31.
[0122] Furthermore, as shown in Figures 7 and 9 to 11, by attaching 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 to the front floor panel 11 via a common mounting member 67, the space required for attaching the front seat center console section 50 and the second driving battery case 44 to the front floor panel 11 can be made compact. Therefore, the second driving battery case 44 can be extended further forward, ensuring sufficient battery capacity.
[0123] Additionally, because the height of the second drive battery case 44 can be kept low, there is increased freedom in the height of the top surface 711 of the rear seat center console unit 70, which serves as a decorative surface covering the second drive battery case 44. For example, without being affected by the height of the second drive battery case 44, the top surface 711 of the rear seat center console unit 70 can be set to an appropriate height that allows rear seat passengers to easily access the operation input unit 83 for audio and the like provided on the top surface 711 and does not interfere with the rear seat armrest 34, which can be folded forward.
[0124] In one embodiment of the present invention, as shown in FIG. 11, the item storage section 53 provided at the rear of the front seat center console section 50 and the front end section 44F of the second driving battery case 44 are fastened together to the mounting member 67 using the same fasteners, bolt B2 and nut N2.
[0125] According to the above configuration, the attachment portion where the front seat center console portion 50 and the second driving battery case 44 are attached to the front floor panel 11 via the attachment members 67 can be made more compact.
[0126] In one embodiment of the present invention, as shown in Figures 7, 9 to 11, the second driving battery case 44 extends forward from the rear end 50r of the front seat center console portion 50, and the front end 44F is attached to the front floor panel 11 via an attachment member 67 in front of the rear end 50r of the front seat center console portion 50.
[0127] According to the above configuration, the mounting member 67 is positioned forward of the rear end 50r of the front seat center console portion 50, so the second driving battery case 44 can be extended forward of the rear end 50r of the front seat center console portion 50, thereby ensuring more battery capacity than when the second driving battery case 44 is attached to the front floor panel 11 behind the rear end 50r of the front seat center console portion 50.
[0128] Furthermore, by attaching the front end 44F of the second driving battery case 44 to the front floor panel 11 via an attachment member 67 forward of the rear end 50r of the front seat center console portion 50, the fore-and-aft length of the opening 76 that communicates in the vehicle width direction between the forward extension portion of the second driving battery case 44 and the front floor panel 11 can be secured.
[0129] In one embodiment of the present invention, as shown in FIG. 7, a front seat center console section 50 is provided with an item storage section 53 inside, and has a rear seat air outlet 60 located rearward of a rear wall 534 of the item storage section 53 of the front seat center console section 50 and above an upper surface 44u of a front end portion 44F of a second drive battery case 44, and the front end portion 44F of the second drive battery case 44 is positioned close to the rear of the rear wall 534 of the item storage section 53, and the rear seat air outlet 60 protrudes forward so as to be supportable from directly below.
[0130] Additionally, the rear end (66b) of the rear seat supply duct 62 is connected to the rear seat air outlet 60 and is supported from directly below by the second driving battery case 44 via a bracket (not shown). As a result, the second driving battery case 44 protrudes forward so as to be able to support the rear seat air outlet 60 from directly below.
[0131] According to the above configuration, the rear seat air outlet 60 is supported by the second driving battery case 44, which is spaced upward from the front floor panel 11, and can therefore be stably installed while ensuring a predetermined height facing the rear seat occupants.
[0132] The second driving battery case 44 can be extended forward up to the rear of the rear wall 534 of the item storage section 53, so that the battery capacity can be ensured.
[0133] In one embodiment of the present invention, as shown in Figures 2 and 6, a tunnel section 22 is provided in the center of the front floor panel 11 in the vehicle width direction, extending along the fore-and-aft direction and bulging upward relative to the surrounding area, and as shown in Figures 7, 9 to 11, an attachment member 67 is fixed to the upper surface 22u of the tunnel section 22 so as to be able to support 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 from below.
[0134] According to the above configuration, by fixing the mounting member 67 to the upper surface portion 22u of the tunnel portion 22, the height of the tunnel portion 22, which is highly rigid without being made bulky in the vertical direction, can be used to firmly support both the item storage section 53 and the front end portion 44F of the second driving battery case 44 in a compact form in the vertical direction.
[0135] In one embodiment of the present invention, a rear seat armrest 34 that can be folded forward is provided directly above the second driving battery case 44, as shown in FIG. 3 and indicated by phantom lines in FIG. 7.
[0136] With this configuration, as described above, the second drive battery case 44 can be extended further forward, thereby ensuring battery capacity while keeping its height low. Therefore, even though the second drive battery case 44 is provided above the floor panel 1 and between the seat cushions 30C, 31C of the left and right rear seats 30, 31, the rear seat armrest 34, which is folded forward above the second drive battery case 44, can be set to an appropriate height where rear seat passengers can rest their arms without interfering with the second drive battery case 44 or the rear seat center console portion 70 that covers the second drive battery case 44.
[0137] In one embodiment of the present invention, as shown in Figures 4 and 8, an intermediate backrest portion 32 is provided between the seat backs 30B, 31B of the left and right rear seats 30, 31, and the second driving battery case 44 extends forward so as to be able to support the folded-down intermediate backrest portion 32 from below.
[0138] With this configuration, as described above, the second driving battery case 44 can be extended further forward, thereby ensuring battery capacity while keeping its height low. Therefore, when the intermediate backrest 32 is tilted forward so that it can be supported from below by the second driving battery case 44, the height of the passenger compartment 2, i.e., the height between the tilted intermediate backrest 32 and the ceiling of the passenger compartment 2, can be ensured.
[0139] Furthermore, in this embodiment, 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 (e.g., L30B) of the seat backs 30B, 31B of the left and right rear seats 30, 31 (see Figure 7), so when the seat backs 30B, 31B and the intermediate backrest portion 32 of the left and right rear seats 30, 31 are all folded forward, an expanded luggage compartment floor surface 2Fa that is approximately flush (fully flat) can be formed, as shown in Figures 4 and 8.
[0140] In the configuration of this invention and the correspondence with the above-mentioned embodiment, the floor pan corresponds to the front floor panel 11, and similarly The left and right rear seat backs are compatible with seatbacks 30B, 30B. The left and right rear seats are compatible with seat cushions 30C and 31C. The drive battery case corresponds to the second drive battery case 44, The front end of the driving battery case corresponds to the front end 44F of the second driving battery case 44, The upper surface of the driving battery case corresponds to the upper surface 44u of the second driving battery case 44, The rear of the center console for the front seats corresponds to the storage compartment 53. The rear end of the storage compartment corresponds to the rear wall 534 of the storage compartment 53. The rear seat cushion pan is compatible with the rear seat cushion panel 131. The same fasteners correspond to the bolt B2 and nut N2, but the present invention is not limited to the configuration of the above-described embodiment, and many other embodiments can be obtained.
[0141] For example, in the above-described embodiment, the upper surface 43u of the first driving battery case 43 is exposed toward the space of the luggage compartment 2a so as to form part of the expanded luggage compartment floor 2Fa, as in the present embodiment. However, the present invention is not limited to this, and even when the upper surface 43u is covered with a covering member such as a decorative panel, mat, luggage compartment partition board, or the like, and these covering members form the actual upper surface of the first driving battery case 43, the upper surface 43u of the first driving battery case 43 is still considered to form part of the expanded luggage compartment floor 2Fa.
[0142] Furthermore, the vehicle of the present invention may be, for example, a 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. [Explanation of symbols]
