Description

[Technical Field]

[0001] The present disclosure relates to vehicles. [Background technology]

[0002] In a conventional vehicle, JP 2020-059359 A (Patent Document 1) describes a vehicle in which an electric storage device and an exhaust pipe are arranged adjacent to each other in the width direction of the vehicle below a floor panel, and when viewed from above, one side of the electric storage device is fixed to a vehicle frame member located between the exhaust pipe and a side wall portion of the electric storage device located on one side of the width direction, and the other side of the electric storage device is fixed to a vehicle frame member located on the other side of the width direction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-059359 Summary of the Invention [Problem to be solved by the invention]

[0004] The exhaust pipe extends along the front-to-rear direction of the vehicle, but includes a portion at the front that faces inward in the vehicle width direction. Because the electric power storage device is positioned so as not to interfere with the exhaust pipe, if the electric power storage device is large, there may be a location on one side in the width direction between the exhaust pipe and a side wall of the electric power storage device where it is difficult to provide a fixed portion. On the other hand, because no exhaust pipe is positioned on the other side in the width direction, the other side of the electric power storage device can be fixed to a vehicle frame member without being restricted by the exhaust pipe.

[0005] In this way, if an area is formed in the width direction where one side of the storage device is not fixed but the other side of the storage device is fixed, there is a concern that the storage device will be more likely to deform when a load is input to the storage device.

[0006] 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 that can suppress deformation of an electricity storage device when an external load is input to the electricity storage device. [Means for solving the problem]

[0007] A vehicle according to a first aspect of the present disclosure includes a vehicle body including a floor panel and a frame member, an electric power storage device disposed below the floor panel, and a plurality of fastening portions for fastening the electric power storage device to the frame member. The frame member includes a first member and a second member extending along the front-rear direction of the vehicle and spaced apart in the width direction of the vehicle. The electric power storage device has a first side wall portion and a second side wall portion spaced apart in the width direction, and a front wall portion located on the front side and connecting the first side wall portion and the second side wall portion. The plurality of fastening portions include a plurality of first fastening portions located on the first side wall portion side and fixed to the first member, and a plurality of second fastening portions located on the second side wall portion side and fixed to the second member. The first fastening portion located most forward of the plurality of first fastening portions is located forward of the second fastening portion located most forward of the plurality of second fastening portions. The electric power storage device has a protrusion that protrudes upward on the front wall portion side. The protrusion is disposed so as to overlap a portion of the vehicle body in the vertical direction.

[0008] Generally, when the most forward first fastening portion of the plurality of first fastening portions arranged on the first side wall portion is located forward of the most forward second fastening portion of the plurality of second fastening portions arranged on the second side wall portion, the power storage device is likely to deform upward in a portion forward of an imaginary line connecting the most forward first fastening portion and the most forward second fastening portion. However, as in the above configuration, the protruding portion provided on the front wall portion so as to protrude upward is positioned to overlap a portion of the vehicle body in the vertical direction, so that when an upward load is input to the power storage device, the protruding portion abuts against the vehicle body. This makes it possible to suppress upward deformation of the power storage device in a portion forward of the most forward second fastening portion.

[0009] A vehicle according to a second aspect of the present disclosure includes a vehicle body including a floor panel and a frame member, an electric power storage device disposed below the floor panel, and a plurality of fastening portions for fastening the electric power storage device to the frame member. The frame member includes a first member and a second member extending along the front-rear direction of the vehicle and spaced apart in the width direction of the vehicle. The electric power storage device has a first side wall portion and a second side wall portion spaced apart in the width direction, and a front wall portion located on the front side and connecting the first side wall portion and the second side wall portion. The plurality of fastening portions include a plurality of first fastening portions located on the first side wall portion side and fixed to the first member, and a plurality of second fastening portions located on the second side wall portion side and fixed to the second member. The first fastening portion located most forward of the plurality of first fastening portions is located forward of the second fastening portion located most forward of the plurality of second fastening portions. The power storage device further includes a fixed portion provided with at least a first fastening portion located most forward among the plurality of fastening portions. A protruding portion that protrudes outward in the width direction is provided on the front wall side of the power storage device. The fixed portion extends in the front-rear direction and has a portion that overlaps with the protruding portion in the width direction.

[0010] Generally, the first fastening portion located most forward among the plurality of first fastening portions arranged on the first side wall portion is located forward of the second fastening portion located most forward among the plurality of second fastening portions arranged on the second side wall portion, which makes it easier for the energy storage device to deform in the width direction in front of the second fastening portion located most forward. However, as in the above configuration, the protruding portion provided on the front wall portion so as to protrude outward in the width direction is positioned to overlap a portion of the fixed portion in the width direction, so that when a load is input from the fixed portion toward the second side wall portion, the fixed portion abuts against the protruding portion. This makes it possible to suppress widthwise deformation of the energy storage device in front of the second fastening portion located most forward.

[0011] A vehicle according to a third aspect of the present disclosure includes a vehicle body including a floor panel and a frame member, an electric power storage device disposed below the floor panel, and a plurality of fastening portions for fastening the electric power storage device to the frame member. The frame member includes a first member and a second member extending along the front-rear direction of the vehicle and spaced apart in the width direction of the vehicle. The electric power storage device has a first side wall portion and a second side wall portion spaced apart in the width direction, and a front wall portion located on the front side and connecting the first side wall portion and the second side wall portion. The plurality of fastening portions include a plurality of first fastening portions located on the first side wall portion side and fixed to the first member, and a plurality of second fastening portions located on the second side wall portion side and fixed to the second member. The first fastening portion located most forward of the plurality of first fastening portions is located forward of the second fastening portion located most forward of the plurality of second fastening portions. The vehicle further includes an exhaust pipe disposed along the second side wall portion, and a heater insulator disposed between the exhaust pipe and the second side wall portion. The front wall portion of the power storage device is provided with a protrusion that fits between the second side wall portion and the heater insulator and suppresses a flow of gas from a tip side of the heater insulator toward a space between the second side wall portion and the heater insulator.

[0012] According to the above configuration, the protrusion can suppress the flow of gas from the tip side of the heater insulator toward the space between the first side wall and the heater insulator, thereby suppressing high-temperature gas heated by the exhaust pipe from entering between the second side wall and the heater insulator and suppressing a rise in temperature inside the power storage device via the second side wall.

[0013] In the vehicle according to the first to third aspects of the present disclosure, the power storage device may include a connector block provided on the front wall portion. The connector block may be integrally formed from the same material. The protrusion may be a part of the connector block.

[0014] According to the above configuration, by configuring the protrusion as part of the connector block, it is possible to ensure the rigidity of the protrusion, reduce the number of parts, and suppress upward deformation of the power storage device.

[0015] In the vehicle based on the first to third aspects of the present disclosure, the protruding portion may be provided with a rib.

[0016] According to the above configuration, the provision of the rib can increase the rigidity of the protrusion.

[0017] The vehicle according to the first aspect of the present disclosure may further include a buffer member disposed between the part of the vehicle body and the protruding portion.

[0018] According to the above configuration, the buffer member can suppress transmission of vibrations to the vehicle body side. [Effects of the Invention]

[0019] According to the present disclosure, it is possible to provide a vehicle that can suppress deformation of the power storage device when an external load is input to the power storage device. [Brief explanation of the drawings]

The first member 3 and the second member 4 extend along the front-to-rear direction of the vehicle. The first member 3 and the second member 4 are arranged with a gap between them in the width direction of the vehicle. The first member 3 is located on one side of the vehicle in the width direction, and the second member 4 is located on the other side of the vehicle in the width direction. When viewed from above, the second member 4 is located between the exhaust pipe 101 and a second side wall portion 122B described later. The electricity storage device 10 is fixed to the first member 3 and the second member 4.

[0026] An electric power storage device 10, an exhaust pipe 101, and a fuel tank 102 are disposed below the floor panel 6. One end of a vehicle wire harness 90 connected to the electric power storage device 10 is also routed below the floor panel 6.

[0027] The power storage device 10 includes a casing 11, an electric device 21, a power storage module 22, and a plurality of fixed portions 71 to 74, 81 to 83. The casing 11 accommodates the electric device 21 and the power storage module 22 therein. The casing 11 includes an upper member 13 and a lower case 12.

[0028] The upper member 13 has a box-like shape that opens downward. The upper member 13 includes a top plate portion 131, a peripheral wall portion 132, and a flange portion 133. The top plate portion 131 forms the top wall of the storage case 11. The peripheral wall portion 132 extends downward from the peripheral edge of the top plate portion 131. The flange portion 133 extends from the lower end of the peripheral wall portion 132 to the outside of the storage case. Note that the upper member 13 may be in the shape of a lid, without the peripheral wall portion 132.

[0029] The lower case 12 has a box-like shape that opens upward. The lower case 12 includes a bottom plate portion 121, a peripheral wall portion 122, and a flange portion 123. The bottom plate portion 121 faces the top plate portion 131 in the vertical direction. The vertical direction is parallel to the up-down direction of the vehicle. The peripheral wall portion 122 extends upward from the peripheral edge of the bottom plate portion 121. The flange portion 123 extends from the upper end of the peripheral wall portion 122 to the outside of the storage case.

[0030] The flange portion 133 and the flange portion 123 are fastened together in the vertical direction with a plurality of fastening members 150 (see FIG. 3 ), so that the upper member 13 and the lower case 12 are joined together as a single unit, and form a space therein for accommodating the electric device 21 and the electricity storage module 22.

[0031] A partition member 23 is provided in the lower case 12. The partition member 23 separates an area in which the electrical device 21 is disposed from an area in which the power storage module 22 is disposed. The partition member 23 connects, for example, a first side wall portion 122A and a second side wall portion 122B, which will be described later.

[0032] The electrical device 21 is, for example, a junction box. The power storage module 22 includes a plurality of power storage stacks. Each power storage stack is configured by arranging a plurality of power storage cells. The power storage cells are secondary batteries such as nickel-metal hydride batteries or lithium-ion batteries. The power storage cells may use a liquid electrolyte or a solid electrolyte. The power storage cells may be chargeable and dischargeable capacitors.

[0033] The peripheral wall portion 122 includes a first side wall portion 122A, a second side wall portion 122B, a front wall portion 122C, and a rear wall portion 122D. The first side wall portion 122A and the second side wall portion 122B are arranged with a gap in the width direction of the vehicle. The first side wall portion 122A is located on one side in the width direction of the vehicle. The first side wall portion 122A is approximately parallel to the front-rear direction of the vehicle.

[0034] A plurality of fixed portions 71 to 74 are provided on the first side wall portion 122A side. The plurality of fixed portions 71 to 74 are arranged at intervals in the front-to-rear direction of the vehicle. The plurality of fixed portions 71 to 74 are fixed to the first member 3 by fastening members such as bolts and nuts, and a plurality of first fastening portions 31 to 34 are formed at fastening positions of the respective fixed portions. In other words, the plurality of first fastening portions 31 to 34 are portions where the energy storage device 10 is fixed to the first member 3. The plurality of fixed portions 71 to 74 are made of, for example, metal pieces.

[0035] The second side wall portion 122B is located on the other side in the width direction of the vehicle. The second side wall portion 122B has a first portion 122B1 and a second portion 122B2. The first portion 122B1 is located on the front side of the second side wall portion 122B. The first portion 122B1 approaches one side in the width direction of the vehicle as it moves forward. The second portion 122B2 is located behind the first portion 122B1. The second portion 122B2 is approximately parallel to the front-to-rear direction of the vehicle. The distance between the first side wall portion 122A and the second side wall portion 122B on the front side is smaller than the distance between the first side wall portion 122A and the second side wall portion 122B on the rear side.

[0036] A plurality of fixed portions 81 to 83 are provided on the second side wall portion 122B side. The plurality of fixed portions 81 to 83 are arranged at intervals in the front-to-rear direction of the vehicle. The plurality of fixed portions 81 to 83 are arranged on the second portion 122B2 side of the second side wall portion 122B. No fixed portions or second fastening portions are provided on the first portion 122B1 side. The plurality of fixed portions 81 to 83 are fixed to the second member 4 with fastening members such as bolts and nuts, and a plurality of second fastening portions 41 to 43 are formed at fastening positions of the respective fixed portions. In other words, the plurality of second fastening portions 41 to 43 are portions where the power storage device 10 is fixed to the second member 4. The plurality of fixed portions 81 to 83 are formed, for example, from metal pieces.

[0037] The first fastening portion 31, which is located most forward among the multiple first fastening portions 31-34, is located further forward than the second fastening portion, which is located most forward among the multiple second fastening portions 41-44. The first fastening portion 32 and the second fastening portion 41 are located at a distance in the width direction of the vehicle. The first fastening portion 33 and the second fastening portion 42 are located at a distance in the width direction of the vehicle. The first fastening portion 34 and the second fastening portion 43 are located at a distance in the width direction of the vehicle.

[0038] The front wall 122C and the rear wall 122D are spaced apart in the front-to-rear direction. The front wall 122C connects the front ends of the first side wall 122A and the second side wall 122B. The rear wall 122D connects the rear ends of the first side wall 122A and the second side wall 122B.

[0039] A connector block 14 is provided on the front wall portion 122C. A vehicle-side wire harness 90 or the like is connected to the connector block 14. The connector block 14 is made of a metal member such as aluminum. The connector block 14 is integrally formed from the same material. Specifically, the connector block 14 is manufactured by die-casting.

[0040] The connector block 14 includes a main body 141 and a protruding portion 142 that protrudes upward from the main body 141. The protruding portion 142 overlaps the floor panel 6 in the vertical direction. A buffer member 60 is disposed between the upper end of the protruding portion 142 and the floor panel 6. The buffer member 60 is made of an elastic material such as rubber. The buffer member 60 can suppress transmission of vibrations and the like from the protruding portion 142 to the floor panel 6. In addition, as will be described later, when an upward load is applied to the power storage device 10, the buffer member 60 can also absorb part of the external force transmitted to the floor panel 6.

[0041] Although the present embodiment illustrates the case where buffer member 60 is provided, buffer member 60 may be omitted. In this case, protrusion 142 may be in contact with floor panel 6. Furthermore, a gap may be formed between protrusion 142 and floor panel 6 as long as protrusion 142 hits floor panel 6 due to an upward load.

[0042] The exhaust pipe 101 extends in the front-to-rear direction of the vehicle. The exhaust pipe 101 is disposed adjacent to the second side wall portion 122B in the width direction of the vehicle. A gap is formed between the exhaust pipe 101 and the second side wall portion 122B. The above-mentioned multiple fixed portions 81 to 83 are located in this gap. The exhaust pipe 101 includes, on its front side, a portion that extends toward one side in the width direction as it moves forward, and this portion is aligned with the above-mentioned first portion 122B1.

[0043] The fuel tank 102 is disposed behind the rear wall portion 122D. Fuel such as gasoline is stored in the fuel tank 102. The fuel is supplied from the fuel tank 102 to an engine (not shown).

[0044] FIG. 3 is a plan view showing the positions of the protruding portions in the vehicle according to the first embodiment. As shown in FIG. 3, flange portion 133 includes a plurality of bulging portions 134 that bulge forward. The plurality of bulging portions 134 are spaced apart in the width direction of the vehicle on the front and rear sides of the vehicle, and are spaced apart in the front-rear direction of the vehicle on the lateral sides of the vehicle. FIG. 3 shows a portion of flange portion 133 that is located on the front wall portion 122C side. When viewed from above, protruding portions 142 are located in gaps between adjacent bulging portions 134. Providing protruding portions 142 in this manner prevents protruding portions 142 from being located forward of flange portion 133, thereby suppressing an increase in the length of power storage device 10 in the front-rear direction of the vehicle. Furthermore, protruding portions 142 may be provided with ribs 142r along the protruding direction. This increases the rigidity of protruding portions 142.

[0045] Generally, the first fastening portion 31 located most forward among the multiple first fastening portions 31 to 34 arranged on the first side wall portion 122A side is located further forward than the second fastening portion 41 located most forward among the multiple second fastening portions 41 to 43 arranged on the second side wall portion 122B side, so that the storage device 10 is more likely to deform upward in front of the imaginary line connecting the first fastening portion 31 located most forward and the second fastening portion 41 located most forward.

[0046] In vehicle 1 according to the present embodiment, first fastening portion 31 and second fastening portion 42 have the positional relationship described above, but protrusion 142 provided on front wall portion 122C in a state where it protrudes upward is positioned to overlap a part of vehicle body 2 (specifically, floor panel 6) in the vertical direction, so that when an upward load is input to power storage device 10, protrusion 142 abuts against vehicle body 2. This makes it possible to suppress upward deformation of power storage device 10 forward of second fastening portion 41, which is located most forward. This also makes it possible to suppress deformation of floor panel 6.

[0047] (Embodiment 2) Fig. 4 is a plan view showing an electricity storage device fixed to a vehicle frame member in a state adjacent to an exhaust pipe in the width direction of the vehicle in a vehicle according to embodiment 2. Fig. 5 is an enlarged view showing the structure around a third member in a vehicle according to embodiment 2. Vehicle 1A according to embodiment 2 will be described with reference to Figs. 4 and 5.

[0048] Vehicle 1A according to embodiment 2 differs from the vehicle according to embodiment 1 in that it is provided with third member 5 and protrusion 142 is provided so as to be able to abut against third member 5. The other configurations are substantially the same.

[0049] The third member 5 constitutes a part of the frame member included in the vehicle body 2. The third member 5 is located above the upper member 13. The third member 5 extends along the front-rear direction of the vehicle. The third member 5 is disposed between the first member 3 and the second member 4 in the width direction of the vehicle. In this embodiment, the third member 5 is illustrated as being located approximately in the center between the first member 3 and the second member 4, but is not limited to this. The third member 5 may be located closer to the first member 3 or closer to the second member 4, as long as it includes a portion located above the connector block 14.

[0050] A space is formed between the third member 5 and the upper member 13. Wiring may be routed within the space. The third member 5 has a ceiling portion 51, a pair of wall portions 52, and a flange portion 53.

[0051] The pair of wall portions 52 are spaced apart from each other in the vehicle width direction. The upper ends of the pair of wall portions 52 are connected to both ends of the ceiling portion 51 in the vehicle width direction. The flange portions 53 extend from the lower ends of each of the pair of wall portions 52 toward the outside in the vehicle width direction. The flange portions 53 are connected to root portions 52r of the pair of wall portions 52. In the third member 5, the flange portions 53 are bent at the root portions 52r, so that the root portions 52r have high rigidity.

[0052] In the present embodiment, the protrusions 142 overlap the root portions 52r of the pair of wall portions 52 in the vertical direction. Therefore, when a load is input from below to above the energy storage device 10, the protrusions 142 abut against the root portions 52r, thereby suppressing deformation of the energy storage device 10 in the width direction in a region forward of the second fastening portion 41, which is located most forward. As described above, the root portions 52r have high rigidity, and therefore the above effect can be exhibited significantly. Note that a buffer member 60 may be disposed between the root portions 52r and the protrusions 142.

[0053] As described above, the vehicle 1A according to the second embodiment also provides substantially the same effects as the vehicle 1 according to the first embodiment.

[0054] (Embodiment 3) Fig. 6 is a plan view showing an electricity storage device fixed to a vehicle frame member in a state adjacent to an exhaust pipe in the width direction of the vehicle in a vehicle according to embodiment 3. Fig. 7 is an enlarged view showing the structure around a protrusion of a connector block in a vehicle according to embodiment 3. Vehicle 1B according to embodiment 3 will be described with reference to Figs. 6 and 7.

[0055] Vehicle 1B according to embodiment 3 differs from vehicle 1 according to embodiment 1 in the protruding direction of protruding portion 142A and the configuration of fixed portion 70. The other configurations are substantially the same.

[0056] The protruding portion 142A protrudes toward one side in the width direction of the vehicle from the main body 141. When viewed from above, the tip of the protruding portion 142A is located on one side in the width direction of the end portion 21a of the electrical device 21, which is located on the one side in the width direction.

[0057] The fixed portion 70 extends in the front-rear direction. The fixed portion 70 is provided with at least first fastening portions 31, 32. In the present embodiment, the case where the fixed portion 70 is provided with the first fastening portions 31 to 34 is illustrated as an example, but is not limited to this. It is preferable that the position of the front end 70a of the fixed portion 70 is substantially the same as the position of the front end of the protruding portion 142A in the front-rear direction. This allows the fixed portion 70 to be configured short, and reduces a decrease in the strength and rigidity of the fixed portion 70.

[0058] The connector block 14 is fastened and fixed to the front wall portion 122C by fastening members 151 and 152. The fastening member 151 fixes an end portion of the main body portion 141 located on one side in the vehicle width direction to the front wall portion 122C. The fastening member 152 fixes an end portion of the main body portion 141 located on the other side in the vehicle width direction to the front wall portion 122C.

[0059] A gap is formed between the protruding portion 142A and the front wall portion 122C, and a buffer member 61 is disposed in the gap. The buffer member 61 is made of an elastic material such as rubber. This can prevent the protruding portion 142A from flapping.

[0060] Here, the first fastening portion 31 located most forward among the multiple first fastening portions 31-34 arranged on the first side wall portion 122A side is located further forward than the second fastening portion 41 located most forward among the multiple second fastening portions 41-43 arranged on the second side wall portion 122B side, and therefore no fastening portion is present on the opposite side in the width direction from the first fastening portion 31 located most forward. Generally, in such a case, when an external force is applied from the first side wall portion 122A side to the second side wall portion 122B side, the energy storage device 10 is likely to deform inward in the width direction (the other side in the width direction) at the side of the first fastening portion 31 located most forward.

[0061] In vehicle 1 according to the present embodiment, first fastening portion 31 and second fastening portion 42 have the positional relationship as described above, but protruding portion 142A provided on front wall portion 122C in a state protruding outward in the width direction of the vehicle is positioned to overlap a portion of fixed portion 70 in the width direction of the vehicle, so that when a load is input from fixed portion 70 toward second side wall portion 122B, fixed portion 70 abuts against protruding portion 142A. This makes it possible to prevent power storage device 10A from deforming in the width direction at the side of first fastening portion 31, which is located most forward.

[0062] In this embodiment, the protrusion 142A, the electric device 21, and the partition member 23 are arranged in this order in the front-rear direction. When an external force is applied in the direction of arrow AR1 in FIG. 7 due to a side collision or the like, the protrusion 142A and the partition member 23 are stretched, thereby suppressing bending deformation of the fixed portion 70 and the first side wall 122A, as indicated by the two-dot chain line in FIG. 7. Furthermore, as described above, the tip of the protrusion 142A is located outward of the end 21a of the electric device 21 in the width direction, thereby suppressing the deformed first side wall 122A from colliding with the electric device 21. This suppresses damage to the electric device 21.

[0063] Furthermore, because the end of main body portion 141 located on one side in the width direction of the vehicle is fastened with fastening member 151, when an external force is applied in the direction of arrow AR1 in FIG. 7, the load is also transmitted to fastening member 151 via protruding portion 142A that abuts against fixed portion 70. The load can be supported by shear of fastening member 151. Note that the number of fastening members 151 is not limited to one, and multiple fastening members 151 may be provided at the same position in the width direction. In this case, the strength can be increased by using multiple fastening members 151.

[0064] In addition, by extending the fixed portion 70 in the front-rear direction, the fixed portion 70 can also function as a shock-absorbing material.

[0065] (Fourth embodiment) Generally, a heater insulator is disposed between the side wall of the power storage device and the exhaust pipe. A gap exists between the heater insulator and the side wall of the power storage device, and unless some measures are taken, there is a concern that high-temperature gas heated by the exhaust pipe through which the high-temperature gas passes will enter the gap and rise in temperature inside the power storage device via the side wall of the power storage device.

[0066] The vehicle according to this embodiment is configured to prevent the temperature inside the power storage device from rising due to high-temperature gas flowing outside.

[0067] Fig. 8 is an enlarged plan view showing the structure around the connector block in a vehicle according to embodiment 4. Fig. 9 is a perspective view showing the structure around the connector block in a vehicle according to embodiment 4. Fig. 10 is a cross-sectional view taken along line XX shown in Fig. 9. A vehicle 1C according to embodiment 4 will be described with reference to Figs. 8 to 10.

[0068] Vehicle 1C according to the fourth embodiment differs from vehicle 1 according to the first embodiment in that it includes heater insulator 190, heat insulating member 17, and the direction in which protrusion 142 protrudes. The other configurations are substantially the same.

[0069] The heater insulator 190 is disposed between the second side wall portion 122B and the exhaust pipe 101. The heater insulator 190 is provided along the second side wall portion 122B. The front side of the heater insulator 190 is provided along the first portion 122B1. The heater insulator 190 is disposed away from the second side wall portion 122B, and a space is formed between the heater insulator 190 and the second side wall portion 122B.

[0070] The protruding portion 142C is inserted between the second side wall portion 122B and the heater insulator 190. The protruding portion 142C includes a first extending portion 143 and a second extending portion 144. The first extending portion 143 extends outward in the width direction from an end portion of the main body portion 141 located on the other side in the vehicle width direction along the front wall portion 122C. The second extending portion 144 extends from an end portion of the first extending portion 143 located on the other side in the vehicle width direction toward the heater insulator 190. The second extending portion 144 extends in a direction perpendicular to the extending direction of the first portion 122B1. The tip of the second extending portion 144 may be in contact with the heater insulator 190 or may be slightly separated from the heater insulator 190. The protruding portion 142C suppresses the flow of gas from the tip side of the heater insulator 190 toward the space between the second side wall portion 122B and the heater insulator 190.

[0071] The heat insulating member 17 covers the front side of the accommodation case 11. On the front side, the heat insulating member 17 covers the top plate portion 131, the peripheral wall portion 132, and the flange portion 133 of the upper member 13. The heat insulating member 17 is disposed between the floor panel 6 and the connector block 14 and the upper member 13. The heat insulating member 17 preferably abuts against the floor panel 6. This prevents outside air heated by the exhaust pipe 101, through which high-temperature gas flows, from entering between the heat insulating member 17 and the floor panel 6.

[0072] Heat insulating member 17 is engaged with connector block 14. Specifically, for example, convex portion 149 of connector block 14 is inserted into through hole 17h provided in heat insulating member 17. Note that the engagement is not limited to through hole 17h and convex portion 149, and convex portion 149 may be inserted into a recess provided on the lower surface side of heat insulating member 17, or heat insulating member 17 and connector block 14 may be engaged with each other by a labyrinth structure.

[0073] As described above, in vehicle 1C according to the present embodiment, protrusion 142C can suppress the flow of gas from the tip side of heater insulator 190 toward the space between second side wall portion 122B and heater insulator 190. This prevents high-temperature gas heated by exhaust pipe 101 from entering between second side wall portion 122B and heater insulator 190, and can suppress a rise in the temperature inside power storage device 10 via second side wall portion 122B.

[0074] (Embodiment 5) 11 is a perspective view showing the structure around the connector block in a vehicle according to embodiment 5. A vehicle 1D according to embodiment 5 will be described with reference to FIG.

[0075] Vehicle 1D according to embodiment 5 differs from vehicle 1C according to embodiment 4 in that it is provided with third member 5 and that heat insulating member 17 is provided with airflow guiding portion 17c. The other configurations are substantially the same. In embodiment 5, heat insulating member 17 does not contact floor panel 6.

[0076] A cutout is provided in the heat insulating member 17, and the cutout constitutes the airflow guide portion 17c. The airflow guide portion 17c guides the outside air heated by the exhaust pipe 101 on the front side of the power storage device 10 to the space between the third member 5 and the upper member 13. The cutout has a shape that slopes or curves upward as it extends toward the rear.

[0077] Even when configured as described above, vehicle 1D according to embodiment 5 can achieve substantially the same effects as vehicle 1C according to embodiment 4. Furthermore, by providing airflow guiding portion 17c, high-temperature gas can be guided rearward through the inside of third member 5.

[0078] Although the heater insulator 190 is omitted in the above-described first to third embodiments, the heater insulator 190 may be provided as in the fourth and fifth embodiments.

[0079] In the above-described first to fifth embodiments, the protrusion is configured as part of the connector block 14, but this is not limited to this and the protrusion may be provided as a separate member on the front wall portion 122C.

[0080] The embodiments disclosed herein are illustrative in all respects and are not restrictive. The scope of the present invention is defined by the claims, and includes all modifications within the meaning and scope of the claims. [Explanation of symbols]
