Mode for Carrying Out the Invention

[0011] An example of a vehicle for explaining an embodiment of the present invention will be described based on the attached drawings. In the drawings, the direction of view shall be in the direction of the reference numerals. In addition, in this specification and the like, for the sake of simplicity and clarity of explanation, the front, rear, left, and right, and up and down directions are described according to the direction seen from the driver of the vehicle, and in the drawings, the front of the vehicle is shown as Fr, the rear as Rr, the left as L, the right as R, the upper as U, and the lower as D.

[0012] The vehicle 1 shown in FIG. 1 is an electric vehicle such as, for example, a battery-powered electric vehicle, a hybrid vehicle (including a plug-in hybrid vehicle), a fuel cell vehicle, etc. This vehicle 1 includes a vehicle body 2, a seat 3, and a battery pack 10. The vehicle body 2 constitutes the skeleton of the vehicle 1, and the battery pack 10 stores and discharges electric power to be supplied to a motor M or the like that serves as a drive source of the vehicle.

[0013] The vehicle body 2 includes a floor panel 4. The floor panel 4 constitutes a part of the skeleton at the lower part of the vehicle. Although not shown in the figure, the vehicle body 2 may also include, as members constituting the skeleton at the lower part of the vehicle, a pair of side sills extending in the longitudinal direction of the vehicle along both side portions of the floor panel 4, a cross member spanned between the pair of side sills, and the like. The seat 3 is installed on the floor panel 4 and is configured to be movable in the longitudinal direction of the vehicle.

[0014] The battery pack 10 is also installed on the floor panel 4 and is disposed below the seat 3 in the example shown in FIG. 1. A recess 5 is formed in the floor panel 4, and the battery pack 10 is housed in the recess 5. By housing the battery pack 10 in the space under the seat that becomes a dead space, the interior space of the vehicle 1 can be expanded.

[0015] FIGS. 2 and 3 show the positional relationship between the battery pack 10 and the seat 3. FIG. 2 shows a state in which the seat 3 movable back and forth is disposed at the most forward position, and FIG. 3 shows a state in which the seat 3 is disposed at the most backward position. In the state where the seat 3 is disposed at the most forward position, the battery pack 10 is covered by the seat 3. On the other hand, in the state where the seat 3 is disposed at the most backward position, the front portion of the battery pack 10 is exposed from the seat 3. Basically, it is preferable that the battery pack 10 is covered by the seat 3 regardless of the forward and backward movement of the seat 3, but depending on the installation conditions of the seat 3 and the battery pack 10, the amount of movement of the seat 3, etc., a part of the battery pack 10 may be exposed from the seat 3 as shown in FIG. 3, for example.

[0016] As shown in Figures 4 and 5, the battery pack 10 comprises a battery 11 and a case 12 that houses the battery 11. The battery 11 includes a plurality of battery cells. The battery cells are, for example, lithium-ion batteries or nickel-metal hydride batteries using a liquid electrolyte, or all-solid-state batteries using a solid electrolyte. The battery 11 is typically modularized with a plurality of battery cells connected in series and / or parallel.

[0017] The case 12 includes a case body 13 and a case cover 14. The case body 13 is formed in a tray shape capable of accommodating the battery 11. The case body 13 is made of a metal plate material such as aluminum alloy or steel. The case cover 14 covers the case body 13 from above.

[0018] Case 12 further houses an intake fan 15, electrical equipment such as a junction box and busbars. The junction box controls the connection between the vehicle's charging system and the battery pack 10, and the connection between the inverter that drives the motor M and the battery pack 10. The busbars connect the modular batteries 11 to each other and also connect the batteries 11 to the junction box. The intake fan 15 introduces outside air into the case 12 to cool the batteries 11 and electrical equipment.

[0019] The case cover 14 is provided with an opening 16, and an attachment 17 is mounted so as to cover the opening 16 from above. The case cover 14 and the attachment 17 constitute the top plate portion of the case 12, and the attachment 17 is provided with an outside air inlet 18 that leads to the inside of the case 12. The outside air inlet 18 is located at the front of the top plate portion of the case 12, and the front of the top plate portion of the case 12 is the part that is exposed from the sheet 3 when the sheet 3 is in its most retracted position. Note that the case cover 14 and the attachment 17 may be made of a single component.

[0020] The battery pack 10 further includes a cover member 20 that covers the outside air inlet 18 from above. The cover member 20 has a side wall 21 that surrounds the outside air inlet 18 and a top wall 22. The side wall 21 is provided with an air intake port 23 that leads to the outside air inlet 18. The outside air drawn in through the air intake port 23 flows into the duct 19 through the outside air inlet 18 and is guided by the duct 19 to the intake fan 15.

[0021] Figures 6 and 7 show examples of configurations around the outside air inlet 18 and the air intake 23. In the examples shown in Figures 6 and 7, the attachment 17 has two outside air inlets 18 spaced apart in the vehicle width direction. Two cover members 20, provided for each outside air inlet 18, are attached to the attachment 17.

[0022] The side walls 21 of the cover member 20 include a left wall 24 and a right wall 25 that face each other in the vehicle width direction with the outside air intake 18 in between, and a rear wall 26 (see Figure 5) positioned behind the outside air intake 18. The front wall 27 that surrounds the outside air intake 18 together with the left wall 24, the right wall 25, and the rear wall 26 extends from the attachment 17, but may also be provided on the cover member 20.

[0023] The left wall 24 and the right wall 25 are inclined so as they move from the lower end to the upper end, approaching the central axis C1 of the outside air inlet 18. The intake port 23 consists of a first intake port 30 provided in the left wall 24 and a second intake port 31 provided in the right wall 25. The first intake port 30 and the second intake port 31 are provided with grids that divide the openings vertically and horizontally, and these grids prevent foreign matter from entering the cover member 20 from the outside to the inside.

[0024] The cover member 20 further comprises a first canopy wall 32 and a second canopy wall 33. The first canopy wall 32 protrudes from the left wall 24 above the first air intake 30 in the direction of opening the first air intake 30 (to the left). The second canopy wall 33 protrudes from the right wall 25 above the second air intake 31 in the direction of opening the second air intake 31 (to the right). In the examples shown in Figures 6 and 9, the ceiling wall 22 is extended to the left and right, and the first canopy wall 32 and the second canopy wall 33 are formed from the extended portion of the ceiling wall 22. However, the first canopy wall 32 and the second canopy wall 33 may be formed separately from the ceiling wall 22.

[0025] As described above, the left wall 24 and the right wall 25 are inclined so that they approach the central axis C1 of the outside air inlet 18 from the lower end to the upper end. Therefore, the lower end of the first air intake 30 provided in the left wall 24 is located furthest from the central axis C1. And, as viewed from the central axis C1, the tip of the first canopy wall 32 is located further away than the distal end (lower end) of the first air intake 30. Similarly, the lower end of the second air intake 31 provided in the right wall 25 is located furthest from the central axis C1, and as viewed from the central axis C1, the tip of the second canopy wall 33 is located further away than the distal end (lower end) of the second air intake 31.

[0026] The battery pack 10, which is installed on the floor panel 4, is at risk of being exposed to foreign objects such as pebbles attached to the soles of occupants' shoes or liquids such as beverages that fall onto the floor. However, since the tip of the first visor wall 32 is located further away from the distal end of the first air intake 30, and the tip of the second visor wall 33 is located further away from the distal end of the second air intake 31, the first air intake 30 and the second air intake 31 are shielded from above by the first visor wall 32 and the second visor wall 33. This prevents foreign objects that fall onto the floor from entering the inside of the case 12 through the first air intake 30 and the second air intake 31.

[0027] Furthermore, foreign objects may move across the floor in the longitudinal direction of the vehicle due to the forward or backward tilting of the vehicle 1, or due to acceleration or deceleration. However, the first air intake 30 and the second air intake 31 are provided on the left wall 24 and the right wall 25 of the cover member 20 and open in the vehicle width direction. This prevents foreign objects moving across the floor in the longitudinal direction of the vehicle from entering the interior of the case 12 through the first air intake 30 and the second air intake 31.

[0028] Furthermore, the battery pack 10 is positioned below the seat 3, which is movable forward and backward, and as shown in Figure 3, the cover member 20 located at the front of the battery pack 10 is exposed when the seat 3 is moved to its furthest back position. However, since the first air intake 30 and the second air intake 31 are shielded from above by the first and second visor walls 32 and 33, it is possible to prevent the inside of the case 12 from being seen through the first and second air intake 30 and 31.

[0029] In particular, since the first air intake 30 and the second air intake 31 are located on the left wall 24 and the right wall 25 of the cover member 20, rather than on the front wall 27, which is highly likely to be peered into by the occupants, it is possible to more reliably prevent the inside of the case 12 from being seen through the first air intake 30 and the second air intake 31.

[0030] From the viewpoint of suppressing the intrusion of foreign matter into the case 12, the attachment 17 has a cylindrical portion 40 that extends upward from the edge of the outside air inlet 18. A recess 41 is formed between the cylindrical portion 40 and the left wall 24, right wall 25, rear wall 26, and front wall 27 that surround the cylindrical portion 40. Even if foreign matter enters the interior of the cover member 20 through the first air intake port 30 and the second air intake port 31, the foreign matter will accumulate in the recess 41. This makes it possible to more reliably suppress the intrusion of foreign matter into the case 12.

[0031] Foreign matter that accumulates in the recess 41 is discharged through an outlet provided in the side wall 21 of the attachment 17 or cover member 20. At least one outlet is sufficient, but in the example shown in Figures 6 and 7, outlets are provided in the rear wall 26 and the front wall 27, which are opposite each other in the vehicle's longitudinal direction, among the left wall 24, right wall 25, rear wall 26, and front wall 27 surrounding the cylindrical portion 40. Foreign matter accumulated in the recess 41 is discharged, for example, through a first outlet 42 provided in the rear wall 26 when the vehicle 1 tilts backward or accelerates. Also, foreign matter accumulated in the recess 41 is discharged, for example, through a second outlet 43 provided in the front wall 27 when the vehicle 1 tilts forward or decelerates.

[0032] Figure 8 shows the airflow flowing into the outside air inlet 18 through the first air intake port 30 and the second air intake port 31. As described above, the first eaves wall 32 and the second eaves wall 33 prevent foreign matter from entering the inside of the case 12 through the first air intake port 30 and the second air intake port 31, and also prevent visibility into the inside of the case 12, thus making it possible to simplify the flow path of outside air from the first air intake port 30 and the second air intake port 31 to the outside air inlet 18.

[0033] Therefore, in the example shown in Figure 8, there is no partition wall to shield the upper end opening of the cylindrical portion 40 leading to the outside air inlet 18 from the first air intake port 30 and the second air intake port 31. That is, the upper end opening of the cylindrical portion 40 is exposed when viewed from the first air intake port 30 and the second air intake port 31. This allows for a smoother airflow through the first air intake port 30 and the second air intake port 31 to the outside air inlet 18, increasing the amount of outside air introduced into the case 12 and improving the cooling efficiency of the battery 11 and electrical equipment.

[0034] Preferably, the upper end of the cylindrical portion 40 is located below the lower ends of the first air intake port 30 and the second air intake port 31. This prevents outside air flowing in from the lower parts of the first air intake port 30 and the second air intake port 31 from colliding with the outer surface of the cylindrical portion 40, thereby suppressing turbulence in the airflow.

[0035] Preferably, the cylindrical portion 40 has a funnel shape that gradually approaches the central axis C1 of the outside air inlet 18 from the upper end to the lower end of the cylindrical portion 40. This straightens the airflow flowing into the outside air inlet 18 through the upper end opening of the cylindrical portion 40, further increasing the amount of outside air introduced into the case 12. In the example shown in Figure 8, the cylindrical portion 40 has an annular extension 44 extending downward from the upper end of the cylindrical portion 40 on the inside of the cylindrical portion 40, and the extension 44 is formed in a funnel shape. Alternatively, the thickness of the cylindrical portion 40 may be gradually increased from the upper end to the lower end of the cylindrical portion 40, so that the entire cylindrical portion 40 has a funnel shape.

[0036] Figures 9 and 10 show modified versions of the cover member 20, in which the first canopy wall 32 has a funnel shape that gradually approaches the central axis C2 of the first air intake port 30 from its tip to its base. Similarly, the second canopy wall 33 has a funnel shape that gradually approaches the central axis C3 of the second air intake port 31 from its tip to its base. This straightens the airflow that flows into the outside air inlet 18 through the first air intake port 30 and the second air intake port 31, and further increases the amount of outside air introduced into the case 12.

[0037] In the example shown in Figure 9, the ceiling wall 22 of the cover member 20 is extended to the left and right, and the first canopy wall 32 and the second canopy wall 33 are formed from the extended portion of the ceiling wall 22. On the other hand, in the example shown in Figure 10, the first canopy wall 32 and the second canopy wall 33 are made of a flexible sheet material such as felt and are joined to the ceiling wall 22 by an appropriate method such as adhesive.
