[0005] [Patent Document 1] JP 2020-58150 A Summary of the Invention [Problem to be solved by the invention]
[0006] In order to stabilize the vehicle's range, the battery (electricity storage device) installed in the vehicle may be replaced with a new battery. In this case, by attaching the battery to the bottom side of the vehicle body so that it can be replaced, the battery replacement work can be easily performed from outside the vehicle.
[0007] However, when the battery is attached to the bottom of the vehicle body, the bottom side of the battery may protrude below the bottom of the vehicle body, and the bottom of the vehicle body and the bottom of the battery may not be flush with each other. In this case, there is a concern that running resistance may be generated due to a step formed between the bottom of the vehicle body and the bottom of the battery.
[0008] The present disclosure has been made in consideration of the above-mentioned problems, and an object of the present disclosure is to provide a vehicle in which an energy storage device can be installed in a replaceable manner and which can reduce the rolling resistance caused by the portion of the energy storage device that protrudes downward from the bottom of the vehicle body. [Means for solving the problem]
[0009] The vehicle according to the present disclosure includes a vehicle body having a bottom, a main body having a front wall and a rear wall facing each other in the front-rear direction of the vehicle body, and a lower surface, and includes an electric storage device replaceably fixed to the bottom, and a straightening plate having a tip portion at a position away from the bottom. A protrusion protruding from the main body along the front-rear direction is provided on the lower surface side of the main body. In a fixed state in which the electric storage device is fixed to the vehicle body, the lower surface of the main body is located below the bottom. The straightening plate is provided so as to be able to face at least one of the front wall and the rear wall in the front-rear direction, and is provided so as to be able to rotate between a state in which the tip portion is close to the electric storage device and a state in which the tip portion is away from the electric storage device. In the fixed state, the protrusion abuts against the straightening plate, thereby maintaining a state in which the straightening plate covers at least one of the front wall and the rear wall portions located below the bottom.
[0010] According to the above configuration, when the electric storage device is removed and moved downward, the electric storage device can be easily moved by rotating the straightening plate in a direction away from the electric storage device (more specifically, the front wall portion or the rear wall portion). Furthermore, when the electric storage device is attached, the electric storage device is moved upward with the protruding portion provided on the electric storage device abutting against the straightening plate, and the electric storage device is fixed to a predetermined location on the vehicle body. At this time, the straightening plate rotates so as to approach the electric storage device (more specifically, the front wall portion or the rear wall portion), and the protruding portion supports the tip end side of the straightening plate, thereby maintaining a state in which the straightening plate covers at least one of the front wall portion and the rear wall portion of the portion located below the bottom of the vehicle body. This makes it possible to adjust the air flow along the electric storage device and reduce the running resistance. Furthermore, the straightening plate provided in such a rotatable manner makes it possible to replace the electric storage device, and when the electric storage device is attached, the straightening plate can be easily placed at a predetermined position by abutting the protruding portion against the straightening plate.
[0011] In the vehicle based on the present disclosure, the air straightening plate may be divided into a plurality of pieces in the left-right direction of the vehicle body.
[0012] According to the above configuration, the airflow can be adjusted over a wide range by using a plurality of air straightening plates, thereby reducing running resistance.
[0013] In the vehicle based on the present disclosure, the air straightening plate may include a first air straightening plate arranged to face the front wall portion from the front side. The front wall portion may include a protruding wall portion protruding toward the front side in a central portion in the left-right direction of the vehicle body. Fastening portions for fixing the power storage device to the bottom portion may be provided on both outer sides of the protruding wall portion in the left-right direction. The first air straightening plate may include overhanging portions that overhang both outer sides in the left-right direction beyond the protruding wall portion. In the fixed state, the overhanging portions may have a portion located forward of the fastening portions.
[0014] According to the above configuration, the protruding portion can prevent foreign matter from adhering to the fastening portion.
[0015] In the vehicle according to the present disclosure, the main body may include a housing case having the front wall and the rear wall and housing the power storage module, and a panel member covering the housing case from below and constituting the lower surface. In this case, the protrusion may be provided on the panel member.
[0016] According to the above configuration, the storage case can be protected by the panel member that covers the storage case from below.
[0017] In the vehicle according to the present disclosure, the protrusion may have an insertion portion that is inserted into the air straightening plate in the fixed state. The air straightening plate may have an insertion receiving portion into which the insertion portion is inserted.
[0018] According to the above configuration, the insertion portion of the protrusion is inserted into the inserted portion of the air straightening plate, thereby making it possible to suppress flapping of the air straightening plate during traveling.
[0019] In the vehicle based on the present disclosure, the straightening plate may include a first straightening plate having a first tip portion at a position spaced downward from the bottom portion and provided to be able to face the front wall portion from the front side, and a second straightening plate having a second tip portion at a position spaced downward from the bottom portion and provided to be able to face the rear wall portion from the rear side. The protrusion may include a front protrusion protruding forward from the main body portion and a rear protrusion protruding rearward from the main body portion. The first straightening plate may be provided so as to be rotatable between a state in which the first tip portion is close to the front wall portion and a state in which the first tip portion is away from the front wall portion. The second straightening plate may be provided so as to be rotatable between a state in which the second tip portion is close to the rear wall portion and a state in which the second tip portion is away from the rear wall portion. In this case, in the fixed state, the front protrusion may abut against the first current plate, thereby maintaining a state in which the first current plate covers a portion of the front wall portion located below the bottom portion. Also, in the fixed state, the rear protrusion may abut against the second current plate, thereby maintaining a state in which the second current plate covers a portion of the rear wall portion located below the bottom portion.
[0020] According to the above configuration, by covering the front wall portion located below the bottom with the first airflow straightening plate, the airflow flowing from the front side of the vehicle can be straightened and running resistance can be reduced. Also, by covering the rear wall portion located below the bottom with the second airflow straightening plate, turbulence of the airflow on the rear wall side can be suppressed. This can further reduce running resistance. Effect of the Invention
[0021] According to the present disclosure, it is possible to provide a vehicle in which an electricity storage device can be attached in a replaceable manner and in which the running resistance caused by a portion of the electricity storage device that protrudes downward from the bottom of the vehicle body can be reduced.

[0043] Furthermore, the protruding portion may be formed of a plate-like member, or may be formed of a thin member such as a pin. When the protruding portion is formed of a thin member such as a pin, the running resistance caused by the protruding portion can be reduced.
[0044] The air straightening plate 20 adjusts the airflow that flows along the bottom 200b of the vehicle body 200 during traveling. The air straightening plate 20 has a tip portion at a position spaced downward from the bottom 200b. The air straightening plate 20 is provided so as to be rotatable between a state in which the tip portion is close to the electricity storage device 10 and a state in which the tip portion is away from the electricity storage device 10. The air straightening plate 20 includes a first air straightening plate 21 and a second air straightening plate 22.
[0045] The first straightening plate 21 has a plate-like shape. The first straightening plate 21 is provided so as to be able to face the front wall portion 11f from the front side. More specifically, the first straightening plate 21 is provided so as to be able to face the protruding wall portion 11f1 from the front side.
[0046] The first straightening plate 21 has a first tip 21t at a position spaced downward from the bottom 200b. The first straightening plate 21 is provided so as to be rotatable between a state in which the first tip 21t is close to the front wall 11f and a state in which the first tip 21t is away from the front wall 11f.
[0047] The second straightening plate 22 has a plate-like shape and is provided so as to be able to face the rear wall portion 11r from the rear side.
[0048] The second straightening plate 22 has a second tip portion 22t at a position spaced downward from the bottom portion 200b. The second straightening plate 22 is provided so as to be rotatable between a state in which the second tip portion 22t is close to the rear wall portion 11r and a state in which the second tip portion 22t is away from the rear wall portion 11r.
[0049] The support portion 30 rotatably supports the straightening vane 20. In the first embodiment, the support portion 30 supports the straightening vane 20 so that the vane can rotate about a rotation axis parallel to the left-right direction of the vehicle body 200. The support portion 30 is provided on the bottom portion 200b.
[0050] The support portion 30 has a first support portion 31 and a second support portion 32. The first support portion 31 is provided on the front side of the power storage device 10 and rotatably supports the first current rectifying plate 21. The second support portion 32 is provided on the rear side of the power storage device 10 and rotatably supports the second current rectifying plate 22.
[0051] As shown in FIG. 2, when the energy storage device 10 is fixed to the vehicle body 200, the protrusion abuts against the air straightening plate 20, thereby maintaining the air straightening plate 20 covering at least one of the front wall portion 11f and the rear wall portion 11r located below the bottom portion 200b.
[0052] Specifically, in the above-mentioned fixed state, the front protrusion 16 abuts against the first straightening plate 21, i.e., the front protrusion 16 supports the first tip portion 21t side, thereby maintaining the first straightening plate 21 covering the portion of the front wall portion 11f that is located below the bottom portion 200b.
[0053] In addition, in the fixed state, the rearward protrusion 17 abuts against the second straightening plate 22, i.e., the rearward protrusion 17 supports the second tip portion 22t side, thereby maintaining the second straightening plate 22 covering the portion of the rear wall portion 11r that is located below the bottom portion 200b.
[0054] In a state in which the first rectifying plate 21 covers the front wall portion 11f, the first rectifying plate 21 controls the air flowing along the bottom portion 200b. Specifically, the first rectifying plate 21 controls the flow of air so that the air flowing from the front side of the power storage device 10 toward the power storage device 10 flows along the lower surface of the power storage device 10.
[0055] In addition, the second airflow straightening plate 22 controls the air flowing along the bottom portion 200b when covering the rear wall portion 11r. Specifically, the second airflow straightening plate 22 controls the air flow from the lower surface of the electricity storage device 10 to the bottom portion 200b of the vehicle body 200 located on the rear side.
[0056] In this way, the first straightening plate 21 straightens the airflow from the front side of the vehicle, thereby reducing the running resistance. Also, the second straightening plate 22 can suppress turbulence of the airflow on the rear wall side, thereby further reducing the running resistance.
[0057] In addition, the first air straightening plate 21 allows air to flow along the lower surface 11b of the electricity storage device 10, thereby effectively cooling the lower surface 11b of the main body 11. As a result, the cooling efficiency of the electricity storage module 19 housed in the main body 11 can also be improved.
[0058] Fig. 3 is a schematic diagram showing how to replace the power storage device in the vehicle according to the embodiment 1. When replacing the power storage device 10 with a new power storage device, as shown in Fig. 3, the fastening of the power storage device 10 to the vehicle body 200 by the above-mentioned multiple fastening members 80 is released. The release of the fastening may be performed automatically by a tool.
[0059] The energy storage device 10, which has been released from the fastening members 80, is moved downward and transported to a predetermined storage location. When the energy storage device 10 is moved downward, the front protrusion 16 and the rear protrusion 17 move away from the first current rectifying plate 21 and the second current rectifying plate 22.
[0060] As a result, the first current rectifying plate 21 rotates from a state close to the front wall portion 11f to a state away from the front wall portion 11f. The second current rectifying plate 22 rotates from a state close to the rear wall portion 11r to a state away from the rear wall portion 11r. As a result of the first current rectifying plate 21 and the second current rectifying plate 22 rotating in this manner, the upper side of the new electricity storage device can pass through the gap between the first tip portion 21t of the first current rectifying plate 21 and the second tip portion 22t of the second current rectifying plate 22.
[0061] Next, a new electric storage device is placed below the insertion area 200c, and the new electric storage device is moved upward and attached to the vehicle body 200 using the fastening member 80. When the new battery is moved upward, the front side protrusion 16 and the rear side protrusion 17 move upward while abutting against the first current plate 21 and the second current plate 22, so that the first current plate 21 rotates to approach the front wall portion 11f, and the second current plate 22 rotates to approach the rear wall portion 11r. In this state, the electric storage device 10 is fixed to the vehicle body 200, so that the first current plate 21 maintains a state of covering the portion of the front wall portion 11f located below the bottom portion 200b, and the second current plate 22 maintains a state of covering the portion of the rear wall portion 11r located below the bottom portion 200b.
[0062] As described above, in the vehicle 100 according to this embodiment, by providing the above-described straightening plate 20, the energy storage device 10 can be mounted in a replaceable manner, and the running resistance caused by the portion of the energy storage device 10 that protrudes downward from the bottom 200b of the vehicle can be reduced.

[0065] The protrusion has an insertion portion that is inserted into the straightening plate 20 when the power storage device 10 is fixed to the vehicle body 200, and the straightening plate 20 has an inserted portion into which the insertion portion is inserted.
[0066] Specifically, the front side protrusion 16 has a first extending portion 16p that extends upward as an insertion portion, and the rear side protrusion 17 has a second extending portion 17p that extends upward as an insertion portion.
[0067] The first current rectifying plate 21 has a first recess 21c recessed upward as an inserted portion, and the second current rectifying plate 22 has a second recess 22c recessed upward as an inserted portion.
[0068] In the above-mentioned fixed state, the first extension portion 16p is inserted into the first recess 21c and the second extension portion 17p is inserted into the second recess 22c, thereby suppressing fluttering of the first straightening plate 21 and the second straightening plate 22 during driving.
[0069] (Embodiment 3) Fig. 5 is a schematic diagram showing a fixed state in which the power storage device is fixed to the vehicle in the vehicle according to the embodiment 3. With reference to Fig. 5, a vehicle 100B according to the embodiment 3 will be described.

[0072] The panel member 50 covers the lower side of the storage case 110. The panel member 50 may be made of a metal member such as SUS. In the present embodiment, the panel member 50 forms the lower surface 11b of the main body portion 11B.
[0073] The cooling device 40 is disposed between the panel member 50 and the housing case 110. The cooling device 40 cools the power storage module 19 that is in thermal contact with the housing case 110 within the housing case 110 from outside the housing case 110.
[0074] In this embodiment, the protrusions are provided on the panel member 50. Specifically, the front protrusion 16 is provided on the front portion of the panel member 50 so as to protrude forward. The rear protrusion 17 is provided on the rear portion of the panel member 50 so as to protrude rearward.
[0075] In the third embodiment, it is possible to obtain substantially the same effects as in the first embodiment. In addition, by providing the panel member 50, the storage case 110 can be protected.
[0076] (Embodiment 4) Fig. 6 is a bottom view of a vehicle according to embodiment 4. With reference to Fig. 6, a vehicle 100C according to embodiment 4 will be described.
[0077] 6, the vehicle 100C according to the fourth embodiment differs from the vehicle 100 according to the first embodiment in the configuration of the airflow straightening vane 20 (more specifically, the first airflow straightening vane 21C). The other configurations are substantially the same.
[0078] The first straightening plate 21C has overhanging portions 215 that overhang both outside in the left-right direction beyond the protruding wall portion 11f1. The overhanging portions 215 are provided so as to extend toward the front fastening portions 14, 15.
[0079] In the above-described fixed state, the overhanging portion 215 includes a portion located on the front side of the front fastening portions 14, 15. When the front fastening portions 14, 15 are located lower than the bottom portion 200b of the vehicle body, the front fastening portions 14, 15 may be covered from the front side by the portion.
[0080] In this case, the overhanging portion 215 can prevent foreign matter from adhering to the front fastening portions 14, 15.
[0081] (Embodiment 5) Fig. 7 is a bottom view of a vehicle according to embodiment 5. With reference to Fig. 7, a vehicle 100D according to embodiment 5 will be described.
