Description
Technical Field
The present invention relates to an electric vehicle, and more particularly to an electric vehicle having a cooling mechanism for cooling a power storage device by circulating air in a vehicle interior.
Background
An electrically powered vehicle such as an electric vehicle or a hybrid vehicle, which uses a motor as a drive source, is equipped with a power storage device as a power source. In such a vehicle, a battery cooling mechanism is provided for maintaining the temperature of the power storage device within an appropriate range in order to prevent deterioration of the performance of the battery due to abnormal temperature rise. Conventionally, a process of discharging air after cooling the power storage device into the vehicle interior has been performed, but since there is a possibility that the occupant feels uncomfortable when the exhaust gas (exhaust heat) hits the occupant, it is required to ensure a comfortable vehicle interior environment by dispersing the exhaust gas into the vehicle interior and performing the exhaust, etc., so as not to lose the comfort of the occupant. In the vehicle described in patent document 1, a battery cooling structure is adopted in which cooling exhaust gas of a power storage device disposed in a luggage room is discharged into the luggage room, and further, the exhaust gas is discharged to the seat front side via a partition plate between the luggage room and a passenger room. In patent document 2, an exhaust duct of a power storage device in a vehicle interior is connected to a side garnish and is guided to the rear of the vehicle through an exhaust flow passage formed by the side garnish and a side sill.

However, according to the battery cooling structure of patent document 1, since the air is discharged downward of the seat, when the occupant sits on the seat, the exhaust wind may hit the feet of the occupant, which may give the occupant a sense of discomfort. Further, since it is assumed that there is a space below the rear seat, a similar configuration cannot be adopted in a vehicle in which a seat is directly placed on a floor, such as a sedan type vehicle. Further, according to patent document 2, the vehicle in which the power storage device is disposed on the floor of the passenger compartment is not directly adopted in the vehicle in which the power storage device is mounted behind the seat.

Detailed Description
Hereinafter, an electric vehicle according to an embodiment of the present invention will be described with reference to the drawings. In the following description, the front, the rear, the left, the right, the upper, and the lower of the vehicle are shown as Fr, Rr, L, R, U, and D in the drawings, respectively, in terms of the directions of the driver.
< vehicle >
As shown in fig. 1 to 3, an electric vehicle 10 according to the present embodiment includes a luggage room 12 behind a rear seat 11 disposed in a vehicle compartment. The rear seat 11 includes a seat cushion 11a and a seat back 11b erected from behind the seat cushion 11 a. A battery housing space 14 is provided below the luggage room 12 by bending a bottom plate 13 into a concave shape, and a battery unit 20 as a power storage device is disposed in the battery housing space 14. The battery storage space 14 is partitioned from the luggage compartment 12 by a rear floor, not shown, that covers the upper side of the battery unit 20.
Further, the electric vehicle 10 includes: vehicle body side plates 15 which are vehicle body members provided on both right and left sides of the rear seat 11; and a side member 16 that is connected to the vehicle body side panel 15 and extends in the front-rear direction on the side of and below the rear seat 11. The side member 16 is covered with a side garnish 50 on the indoor side, and a space is formed between the side member 16 and the side garnish 50, and an exhaust gas flow passage 51 described later is formed by the space.
The battery unit 20 includes a battery module, a DC-DC converter, a duct fan, and the like, which are not shown, a battery case 21 that houses these components, and a cooling mechanism 22 that is a battery cooling mechanism. The cooling mechanism 22 includes an intake duct 30 and an exhaust duct 40.
< intake duct >
The intake duct 30 extends forward from the battery case 21 through a space formed between the right side vehicle body side panel 15 and a side garnish (not shown) of the luggage compartment 12, and an intake port 31 formed at one end thereof opens near the right shoulder of the rear seat 11. A connection portion 32 formed at the other end of the intake duct 30 is connected to the power storage device inlet 23 provided at the rear portion of the battery case 21.
< exhaust gas duct >
The exhaust duct 40 includes: a duct upstream portion 41 that branches in the right-left direction behind the rear seat 11 and extends in the vehicle width direction; and a pair of duct downstream portions 42(42L, 42R) connected to the left and right ends of the branched duct upstream portion 41 and extending forward. A duct inflow port 45 provided at one end of the duct upstream portion 41 is connected to the power storage device discharge port 24 formed at the front portion of the battery case 21. As shown in fig. 3, at least a part of power storage device discharge port 24 and duct upstream portion 41 is disposed at a position overlapping seat back 11b when viewed from above. The duct upstream portion 41 can be disposed by utilizing the space below the seat back 11b that is tilted backward in this way, and the dead space can be effectively utilized.
The duct downstream portion 42 is constituted by a left duct downstream portion 42L connected to the left end portion of the duct upstream portion 41 and a right duct downstream portion 42R connected to the right end portion of the duct upstream portion 41. The left duct downstream portion 42L and the right duct downstream portion 42R are respectively disposed so as to extend in the front-rear direction through a narrow space between the left and right rear seats 11 and the vehicle body side panel 15 in the vehicle width direction and sandwiched between the rear seats 11 and the floor panel 13 in the up-down direction.
The space for passing the duct downstream portion 42 between the rear seat 11 through which the left duct downstream portion 42L and the right duct downstream portion 42R pass and the vehicle body side panel 15 can be formed by cutting the cushion portions of the seat cushion 11a and the seat back 11b while avoiding the seat frame that is a framework member of the rear seat 11.
By passing the left duct downstream portion 42L and the right duct downstream portion 42R through the cushion portion of the seat cushion 11a, wind noise caused by exhaust gas can be absorbed by the elastic material of the cushion portion to achieve quietness. Since the left duct downstream portion 42L and the right duct downstream portion 42R are formed symmetrically with respect to the center in the vehicle width direction of the vehicle 10, the left duct downstream portion 42L will be described below, and the description of the right duct downstream portion 42R will be omitted.
As shown in fig. 4 and 6, the left duct downstream portion 42L has a vertically long shape having a length L1 in the vertical direction longer than a length L2 in the vehicle width direction. This allows the left duct downstream portion 42L to be disposed in a narrow space between the rear seat 11 and the vehicle body side panel 15. Further, the flow passage area of the left duct downstream portion 42L is ensured, and the exhaust flow velocity can be reduced to suppress wind noise.
As shown in fig. 4, the duct connecting portion 43 of the exhaust duct 40 is connected to the side garnish 50 from the vehicle interior side. As shown in fig. 5, when the duct connection portion 43 is cut in the front-rear direction in a side view, the duct connection portion 43 is disposed between the side member 16 and the rear seat 11. Thereby, the exhaust duct 40 communicates with the exhaust flow path 51, and the exhaust flow path 51 is formed in a space between the side member 16 and the side garnish 50. The exhaust passage 51 communicates with the inside of a pillar garnish, not shown, disposed forward of the rear seat 11, and an exhaust port is provided in the pillar garnish, for example. The position of the exhaust port is not limited to the pillar garnish, and may be a position forward of the rear seat 11.
By disposing the duct connection portion 43 between the side member 16 and the rear seat 11 in this manner, the duct connection portion 43 can be hidden from the vehicle interior, and the interior appearance can be kept from being impaired. Further, the exhaust gas can be discharged from the exhaust port that opens to the vehicle interior in front of the rear seat 11, and the occupant is not given a feeling of discomfort by the exhaust gas contacting the occupant.
The duct connection portion 43 is provided with a partition portion 44 that blocks the exhaust flow path 51 at the rear of the duct connection portion 43. The partition 44 blocks the exhaust gas discharged from the duct connection 43 to the exhaust gas flow passage 51 from flowing to the exhaust gas flow passage 51 behind the duct connection 43. Therefore, exhaust gas can be suppressed from being discharged into the vehicle interior from the webbing through hole through which the seat belt passes, which is provided at a position rearward of the duct connecting portion 43.
< flow of Cooling air >
Next, the flow of cooling air for cooling battery cell 20 will be described.
The air taken into the vehicle interior of the intake duct 30 from the intake port 31 opened near the right shoulder of the occupant of the rear seat flows into the battery case 21 through the connection portion 32 of the intake duct 30 and the power storage device inflow port 23 of the battery case 21. The air having cooled the battery module, the DC-DC converter, and the like flows into the duct upstream portion 41 connected to the power storage device discharge port 24 of the battery case 21, and branches off to the left and right in the duct upstream portion 41.
The branched air flows forward in the left duct downstream portion 42L and the right duct downstream portion 42R, respectively. The left duct downstream portion 42L, which is a long duct, flows forward through a narrow space between the left rear seat 11 and the vehicle body side panel 15 and sandwiched between the left rear seat 11 and the floor panel 13, and flows into the exhaust flow passage 51 through the duct connecting portion 43 disposed at a position overlapping the left rear seat 11 in a side view. The air that has flowed into the exhaust passage 51 flows forward in the exhaust passage 51, and is discharged into the vehicle interior from an exhaust port provided in the left pillar garnish, not shown, at a position forward of the left rear seat 11.
Similarly, the right duct downstream portion 42R flows forward through a narrow space between the right rear seat 11 and the vehicle body side panel 15 and sandwiched between the right rear seat 11 and the floor panel 13, and flows into the exhaust passage 51 through the duct connecting portion 43 disposed at a position overlapping the right rear seat 11 in a side view. The air that has flowed into the exhaust passage 51 flows forward in the exhaust passage 51, and is discharged into the vehicle interior from an exhaust port provided in the right pillar garnish, not shown, at a position forward of the right rear seat 11.
At this time, when the exhaust gas flowing into the exhaust flow path 51 from the pipe connection portion 43 flows rearward, the exhaust gas is discharged from the webbing hole of the seatbelt to the vicinity of the head of the occupant, and the exhaust gas may be accumulated in the vicinity of the headrest of the rear seat 11. In addition, since the vicinity of the headrest is a portion where the temperature is likely to rise by incident light, there is a possibility that the occupant feels a sense of discomfort. However, since the partition portion 44 blocks the exhaust gas to the rear of the duct connecting portion 43, the exhaust gas is not discharged from the webbing hole, and the uncomfortable feeling given to the occupant is prevented.
The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and modifications, improvements, and the like can be appropriately made.
