[0017] The right storage portion 52R and the left storage portion 52L are formed in a symmetric shape with respect to the center in the vehicle width direction. Note that it is not limited to the case where the right storage portion 52R and the left storage portion 52L are formed in a symmetric shape. The right storage portion 52R and the left storage portion 52L may have different shapes.

[0018] In each of the right storage portion 52R and the left storage portion 52L, a plurality of batteries 12 are stored and held via battery holders 56. The number of batteries 12 stored in the right storage portion 52R is the same as the number of batteries 12 stored in the left storage portion 52L. The battery 12 is a replaceable low-voltage type battery 12. The battery 12 can be handled by a general user who does not have handling qualifications.

[0019] The battery 12 stored in the right storage portion 52R is disposed to be inclined rightward with respect to the vertical direction (virtual line L) of the vehicle body 14. The upper end portion 121 of the battery 12 is inclined and stored so as to face the right side of the vehicle body 14. The battery 12 stored in the left storage portion 52L is disposed to be inclined leftward with respect to the vertical direction (virtual line L) of the vehicle body 14. The upper end portion 121 of the battery 12 is inclined and stored so as to face the left side of the vehicle body 14.

[0020] The lid member 48 is provided to be able to open and close the storage opening 46 on the floor surface 34. The lid member 48 opens to release the storage opening 46 when taking out the battery 12 from the battery storage chamber 44. When the lid member 48 closes, the lid member 48 closes the storage opening 46 and the lid member 48 constitutes a part of the floor surface 34.

[0021] The cover member 48 includes a right cover 78R that covers the right storage portion 52R and a left cover 78L that covers the left storage portion 52L. The right cover 78R and the left cover 78L have substantially the same shape. Each of the right cover 78R and the left cover 78L has a cover body 80 and a support end 82 provided at an end of the cover body 80. The cover body 80 is formed in a flat plate shape and faces the storage opening 46. The support end 82 is provided at one end in the width direction of the cover body 80. The support end 82 is disposed at substantially the center in the vehicle width direction of the vehicle body 14. The support end 82 is rotatably supported with respect to the floor surface 34 of the vehicle body 14. The support end 82 is supported along the longitudinal direction of the vehicle body 14.

[0022] The other end in the width direction of the cover body 80 extends in a direction orthogonal to the cover body 80. The other end in the width direction of the cover body 80 is provided with a grip portion 84. The grip portion 84 can be gripped by a user when opening and closing the cover member 48.

[0023] In the vehicle width direction of the vehicle body 14, the right cover 78R and the left cover 78L are spaced apart. A land portion 86 is provided between the right cover 78R and the left cover 78L. The land portion 86 is formed with a constant width in the vehicle width direction and extends in the longitudinal direction of the vehicle body 14.

[0024] When the cover member 48 (right cover 78R, left cover 78L) is rotated toward the storage opening 46 with the support end 82 as a fulcrum, the cover body 80 is arranged in a horizontal state along the vehicle width direction of the vehicle body 14, and the storage opening 46 is closed by the cover bodies 80 of the right cover 78R and the left cover 78L. A part of the side of the battery storage chamber 44 is covered by the extending portion. When the cover member 48 is closed and the storage opening 46 of the battery storage portion 26 is closed by the cover member 48, the cover member 48 and the floor surface 34 of the vehicle body 14 are substantially in the same plane. The cover member 48 constitutes a part of the loading platform 30 together with the floor surface 34. In the passenger compartment 24, luggage B can be loaded on the loading platform 30 (see FIG. 1).

[0025] When the lid member 48 (right cover 78R, left cover 78L) rotates in a direction away from the storage port 46 with the support end 82 as a fulcrum (refer to the two-dot chain line shape in Fig. 2), the lid member 48 inclines so that the other end in the width direction of the cover body 80 becomes upward, and the cover body 80 moves away from the storage port 46 to open the storage port 46 (refer to the two-dot chain line shape in Fig. 2). At this time, the lid member 48 is held in an open state by the support rod 87 that supports the vehicle body 14 and the cover body 80. The support rod 87 prevents the lid member 48 from rotating toward the storage port 46 due to its own weight. That is, in the open state of the lid member 48 with the lid member 48 opened to open the storage port 46, the lid member 48 is positioned above the floor surface 34. At this time, the upper end 481 of the lid member 48 arranged at the uppermost position is the end in the width direction of the cover body 80.

[0026] As shown in Fig. 2, the door 18 includes a right door 88R arranged on the right side in the vehicle width direction of the vehicle body 14, a left door 88L arranged on the left side in the vehicle width direction of the vehicle body 14, and a rear door 88B (refer to Fig. 1) arranged behind the vehicle body 14.

[0027] As shown in Fig. 1, the right door 88R includes a front door 881 arranged on the right side and a rear door 882 arranged behind the front door 881. The left door 88L includes a front door 881 arranged on the left side and a rear door 882 arranged behind the front door 881.

[0028] The drive unit 20 is electrically connected to a plurality of batteries 12 by an electrical component (not shown). The drive unit 20 includes a front-wheel motor 90 that drives each of the front wheels 32F and a rear-wheel motor 92 that drives the rear wheels 32R. The front-wheel motor 90 is arranged on the front side of the vehicle body 14. The drive shaft (not shown) of the front-wheel motor 90 is connected to each front wheel 32F. The rear-wheel motor 92 is arranged on the rear side of the vehicle body 14. The drive shaft (not shown) of the rear-wheel motor 92 is connected to the rear wheels 32R.

[0029] The shelf structure 22 is provided above the lid member 48 in the passenger compartment 24. The shelf structure 22 includes a shelf board 94 formed in a flat plate shape and a support portion 96 provided on the vehicle body 14 and capable of horizontally supporting the shelf board 94.

[0030] The shelf board 94 is formed, for example, from a plate material having strength. The shelf board 94 is formed in a rectangular shape with a certain thickness. As shown in FIG. 3, in the vehicle width direction of the vehicle body 14, the width of the shelf board 94 is formed to be substantially equal to or slightly smaller than the width of both side portions 141 of the vehicle body 14. As shown in FIG. 1, luggage B can be loaded on the upper surface of the shelf board 94.

[0031] The shelf board 94 is detachably provided with respect to the support portion 96. The shelf board 94 includes a front board 98F disposed behind the seat 28 and a rear board 98R disposed behind the front board 98F.

In the open state of the lid member 48 where the lid member 48 is opened to open the storage port 46, the front board 98F is disposed at a position higher than the upper end 481 of the lid member 48. That is, as shown in FIG. 2, the height H1 of the lower surface of the front board 98F (shelf board 94) with respect to the floor surface 34 is greater than the height H2 of the upper end 481 of the lid member 48 with respect to the floor surface 34 (H1 > H2). The upper end 481 of the lid member 48 and the lower surface of the front board 98F are separated in the vehicle height direction. The front board 98F is horizontally supported above the battery storage portion 26 by the support portion 96.

[0032] The rear board 98R is disposed in the luggage compartment 241. For example, the front board 98F and the rear board 98R are formed in a substantially rectangular shape. The rear board 98R is horizontally supported in the luggage compartment 241 by the support portion 96. In the vehicle height direction, the front board 98F and the rear board 98R are supported at the same height. Note that the front board 98F and the rear board 98R may be supported at different heights.

[0033] The front plate 98F and the rear plate 98R are provided with stoppers 100 that protrude upward from the upper surface. The stoppers 100 prevent the luggage B stacked on the upper surface of the shelf board 94 from moving in the front-rear direction of the vehicle body 14. The stoppers 100 are provided at the front end and the rear end of the front plate 98F and the rear end of the rear plate 98R on the upper surface of the shelf board 94, respectively. The stoppers 100 extend in the vehicle width direction on the shelf board 94. When viewed from the front-rear direction of the vehicle body 14, the stoppers 100 are U-shaped and open toward the shelf board 94. A pair of open ends 1001 of the stoppers 100 are inserted and fixed to the upper surfaces of the front plate 98F and the rear plate 98R.

[0034] As shown in FIG. 3, the area of the shelf board 94 is larger than the area of the lid member 48. Specifically, the total area of the shelf board 94, which is the sum of the areas of the front plate 98F and the rear plate 98R, is larger than the total area of the lid member 48, which is the sum of the areas of the right cover 78R and the left cover 78L. The area of the shelf board 94 may be smaller than the area of the lid member 48, but it is preferably 90% or more of the area of the lid member 48.

[0035] The support portion 96 includes a front support member 102F and a rear support member 102R. The shelf board 94 is supported by the front support member 102F and the rear support member 102R.

[0036] The front support member 102F is provided between the seat 28 and the luggage compartment 241 in the passenger compartment 24. The front end portion of the front plate 98F is supported by the front support member 102F.

[0037] As shown in FIG. 2, the front support member 102F is a separation member 104 provided on the floor surface 34 in the passenger compartment 24. The separation member 104 is arranged along the vehicle width direction of the vehicle body 14. The separation member 104 can separate the seat 28 and the luggage compartment 241 in the front-rear direction of the vehicle body 14. The separation member 104 is arranged behind the seat 28 and protrudes upward with respect to the floor surface 34. The separation member 104 is arranged between the seat 28 and the battery storage portion 26. The separation member 104 has a pair of leg portions 106 and a horizontal portion 108 connecting the upper ends of the leg portions 106. The pair of leg portions 106 are arranged at intervals in the vehicle width direction of the vehicle body 14. The lower ends of the leg portions 106 are inserted and fixed to the floor surface 34. The lower ends of the pair of leg portions 106 are insertable and removable with respect to the floor surface 34.

[0038] The horizontal portion 108 is arranged horizontally along the vehicle width direction. The height from the floor surface 34 to the upper part of the horizontal portion 108 is higher than the height H2 of the upper end 481 of the lid member 48 when the lid member 48 is opened. The front end portion of the front plate 98F is placed on the upper part of the horizontal portion 108. The front end portion of the front plate 98F is horizontally supported by the horizontal portion 108.

[0039] By inserting and removing the leg portions 106 of the front support member 102F with respect to the floor surface 34, the front support member 102F is detachable with respect to the floor surface 34. When the shelf structure 22 is not used, the front support member 102F is removed from the floor surface 34.

[0040] As shown in FIG. 2, the rear support member 102R is arranged in the luggage compartment 241. The rear support member 102R is fixed to both side portions 141 of the vehicle body 14 in the passenger compartment 24, respectively. As shown in FIG. 3, the rear support member 102R includes a fixing portion 110 fixed to both side portions 141 of the vehicle body 14, and first and second movable portions 1121 and 1122 that are movable in the horizontal direction with respect to the fixing portion 110. The fixing portion 110 has a mounting member 114 extending in the front-rear direction of the vehicle body 14. The mounting member 114 is formed of, for example, a metal plate. The front end portion and the rear end portion of the mounting member 114 are fixed to both side portions 141 of the vehicle body 14 by fastening members 116. The upper part of the mounting member 114 is fixed to the mounting surface 142 of both side portions 141 of the vehicle body 14.

[0041] The first movable part 1121 and the second movable part 1122 are arranged at intervals in the front-rear direction of the vehicle body 14. The first movable part 1121 is arranged close to the front end of the mounting member 114. The first movable part 1121 supports the rear end of the front plate 98F and the front end of the rear plate 98R. The second movable part 1122 is arranged close to the rear end of the mounting member 114. The second movable part 1122 supports the rear end of the rear plate 98R.

[0042] Each of the first and second movable parts 1121, 1122 has a fixed end 118 and a movable end 120. In the first and second movable parts 1121, 1122, the fixed end 118 and the movable end 120 are arranged linearly with a separation therebetween. The fixed ends 118 of the first and second movable parts 1121, 1122 are arranged on the front side of the vehicle body 14. The fixed ends 118 of the first and second movable parts 1121, 1122 are received in the accommodation holes 122 of the mounting member 114. The accommodation holes 122 open inward in the vehicle width direction in the mounting member 114. The fixed ends 118 of the first and second movable parts 1121, 1122 are supported by the mounting member 114 via the support shafts 124.

[0043] When the shelf structure 22 is not used, that is, when the shelf plate 94 is not supported by the support part 96, with the support shafts 124 as the fulcrums, the movable ends 120 of the first and second movable parts 1121, 1122 rotate toward both side parts 141 of the vehicle body 14, and the first and second movable parts 1121, 1122 are arranged at positions respectively received in the accommodation holes 122 (refer to the two-dot chain line shape in FIG. 3). At this time, the first and second movable parts 1121, 1122 do not protrude inward in the vehicle width direction from the mounting member 114. Incidentally, when the first and second movable parts 1121, 1122 are received in the accommodation holes 122, the first and second movable parts 1121, 1122 may protrude inward in the vehicle width direction from the mounting member 114.

[0044] When the shelf structure 22 is used, with the support shaft 124 as a fulcrum, the movable ends 120 of the first and second movable parts 1121 and 1122 rotate so as to face inward in the vehicle width direction of the vehicle body 14, and the first and second movable parts 1121 and 1122 are in a position substantially orthogonal to the fixed part 110. The first and second movable parts 1121 and 1122 are arranged at positions protruding inward in the vehicle width direction from both side parts 141 of the vehicle body 14.

[0045] In the vehicle width direction, a pair of first movable parts 1121 face each other, and the first movable parts 1121 protrude inward in the vehicle width direction from each other. In the vehicle width direction, a pair of second movable parts 1122 face each other, and the 2 movable part 112 2 protrudes inward in the vehicle width direction from each other. The upper surfaces of the first and second movable parts 1121 and 1122 serve as support surfaces for supporting the shelf board 94 (front board 98F, rear board 98R). The height of the upper surface of the first movable part 1121 with respect to the floor surface 34 is the same as the height of the upper surface of the second movable part 1122. The height of the upper surfaces of the first and second movable parts 1121 and 1122 with respect to the floor surface 34 is substantially the same as the height up to the upper part of the front support member 102F (horizontal part 108). The shelf board 94 is horizontally supported by the upper part of the horizontal part 108 in the front support member 102F, the upper surfaces of the pair of first movable parts 1121, and the upper surfaces of the pair of second movable parts 1122. In the vehicle width direction of the vehicle body 14, the shelf board 94 is supported between the fixed end 118 and the movable end 120 of the first movable part 1121 and between the fixed end 118 and the movable end 120 of the second movable part 1122.

[0046] Next, the case of replacing the battery 12 in the electric vehicle 10 will be described.

[0047] When replacing the battery 12, the user moves the placed luggage B to the shelf structure 22. The user grips the luggage B and moves the luggage B from the upper surface of the lid member 48 used as the floor surface 34 of the luggage compartment 241 to the upper surface of the shelf board 94 arranged above the battery storage part 26 (see FIG. 1).

[0048] The user grips the gripping portion 84 of the lid member 48 and rotates the left cover 78L of the lid member 48 about the support end 82 such that the other end in the width direction faces upward. When the left cover 78L rotates, the storage opening 46 is opened. At this time, the upper end 481 of the lid member 48 does not contact the lower surface of the shelf board 94. The user pulls out the battery 12 upward from the opened storage opening 46, takes it out into the passenger compartment 24, and then takes it out to the outside of the vehicle body 14 through the vehicle body opening 16. After loading a new battery 12 into the battery storage chamber 44 through the storage opening 46, when the user closes the lid member 48, the lid member 48 becomes substantially flush with the floor surface 34 and forms part of the loading platform 30.

[0049] When the shelf structure 22 is not used, after removing the front plate 98F and the rear plate 98R upward from the support portion 96, the separating member 104, which is the front support member 102F, is pulled out upward from the floor surface 34. As shown in FIG. 3, by rotating the first and second movable portions 1121, 1122 of the rear support member 102R about the fixed end 118 such that the movable end 120 faces the vehicle body 14 side, the first and second movable portions 1121, 1122 are accommodated in the accommodation holes 122 (refer to the two-dot chain line shape in FIG. 3). The shelf board 94 (front plate 98F and rear plate 98R) and the separating member 104 may be accommodated in the passenger compartment 24 or taken out to the outside of the electric vehicle 10 through the vehicle body opening 16.

[0053] The shelf structure 22 includes a shelf board 94 formed in a flat plate shape and a support portion 96 provided on the vehicle body 14 in the passenger compartment 24 and capable of horizontally supporting the shelf board 94. By horizontally supporting the shelf board 94 by the support portion 96 provided in the passenger compartment 24, the luggage B moved from the lid member 48 can be loaded on the shelf board 94.

[0054] As shown in FIG. 3, the passenger compartment 24 includes a seat 28 arranged on the front side in the passenger compartment 24 for the passenger to board and a luggage compartment 241 arranged on the rear side in the passenger compartment 24 and having a floor surface 34. The support portion 96 includes a front support member 102F provided between the seat 28 and the luggage compartment 241 and a rear support member 102R arranged in the luggage compartment 241 and fixed to both side portions 141 in the vehicle width direction of the vehicle body 14. The shelf board 94 is supported by the front support member 102F and the rear support member 102R. Accordingly, the front support member 102F and the rear support member 102R can support the shelf board 94 along the front-rear direction in the passenger compartment 24, so that a large loading space for the luggage B in the passenger compartment 24 can be secured.

[0055] As shown in FIG. 2, the front support member 102F is a separation member 104 provided on the floor surface 34 in the passenger compartment 24, protruding upward with respect to the floor surface 34 to separate the seat 28 and the luggage compartment 241 in the front-rear direction of the vehicle body 14, and detachable with respect to the floor surface 34. By using the separation member 104 that separates the seat 28 and the luggage compartment 241 as the front support member 102F, there is no need to newly set the front support member 102F, the interior space of the vehicle can be effectively utilized, and moreover, the manufacturing cost can be reduced. When the shelf structure 22 is not used, the space in the passenger compartment 24 can be effectively utilized by removing the separation member 104.

[0056] As shown in FIG. 3, the rear support member 102R includes a fixing portion 110 fixed to both side portions 141, and first and second movable portions 1121 and 1122 that are provided so as to be rotatable in a horizontal direction with respect to the fixing portion 110 and inward in the vehicle width direction with respect to the fixing portion 110. When supporting the shelf board 94 on the rear support member 102R, the first and second movable portions 1121 and 1122 are arranged at positions protruding inward in the vehicle width direction with respect to the fixing portion 110, and the shelf board 94 is supported by the first and second movable portions 1121 and 1122. Thereby, by rotating the first and second movable portions 1121 and 1122 inward in the vehicle width direction, the shelf board 94 can be supported by the rear support member 102R. When the shelf structure 22 is not used, by rotating the first and second movable portions 1121 and 1122 toward the fixing portion 110 side, the first and second movable portions 1121 and 1122 do not protrude inward in the vehicle width direction, so that the space in the passenger compartment 24 can be effectively utilized.

[0057] In a plan view of the vehicle body 14, the shelf board 94 is arranged at a position overlapping the battery storage compartment 44, and in an open state of the lid member 48 in which the lid member 48 is opened to open the storage port 46, a part of the lid member 48 is located above the floor surface 34.

Thereby, when the lid member 48 is opened to replace the battery 12, the lid member 48 is prevented from contacting the shelf board 94 disposed above the battery storage compartment 44, and the replacement work of the battery 12 can be performed.

[0058] Since the shelf board 94 is detachably provided with respect to the support portion 96, when the shelf structure 22 is not used, the space in the passenger compartment 24 can be effectively utilized by removing the shelf board 94 from the support portion 96. When the shelf structure 22 is not used, the space in the passenger compartment 24 can be effectively utilized by removing the shelf board 94.

[0059] As shown in FIG. 3, since the area of the shelf board 94 is 90% or more of the area of the lid member 48, it is possible to effectively move substantially all of the luggage B loaded on the lid member 48 to the shelf board 94.

One of the first engaging portion and the second engaging portion may be a protrusion (220), and the other may be a recess (224) with which the protrusion is engaged. According to such a configuration, the movement of the shelf board along the upper surface of the support is effectively prevented by the first and second engaging portions formed by the protrusion and the recess.

[0102] (Supplementary Note 10) In the electric vehicle described in Supplementary Note 7 or 8, a plurality of fastening holes (2141, 2142) are provided along the vehicle height direction on both side portions of the vehicle body, and the support may be fixed by a fastening member (116) to any one of the plurality of fastening holes having different height positions from each other. According to such a configuration, the support can be easily fixed or removed with respect to the vehicle body by the fastening member. Furthermore, by selecting the fastening hole to be fastened from among the plurality of fastening holes having different heights, the support can be fixed at different heights in the vehicle height direction. The height of the shelf board in the vehicle interior can be easily changed.

[0103] (Supplementary Note 11) In the electric vehicle according to any one of Appendices 2 to 10, in plan view, the shelf board is disposed at a position overlapping the battery storage chamber, and in the open state of the lid member where the lid member is opened to open the storage port, a part of the lid member is located above the floor surface. In the open state of the lid member, the lid member has an upper end located at the uppermost position, and the height (H1) of the lower surface of the shelf board with respect to the floor surface may be greater than the height (H2) of the upper end of the lid member with respect to the floor surface. According to such a configuration, when the lid member is opened to replace the battery, the lid member is prevented from contacting the shelf board disposed above the battery storage chamber, and the battery replacement work can be performed.

[0104] (Appendix 12) In the electric vehicle according to any one of Appendices 2 to 11, the shelf board may be detachably provided with respect to the support portion. According to such a configuration, when the shelf structure is not used, the space in the vehicle interior can be effectively utilized by removing the shelf board from the support portion. When the shelf structure is not used, the space in the vehicle interior can be effectively utilized by removing the shelf member.

[0105] Note that the present invention is not limited to the above-described disclosure, and various configurations can be adopted without departing from the gist of the present invention.
