Technical Field

The present invention relates to a vehicle equipped with an intake grille for sucking air into a vehicle interior.

Background

An electric Vehicle such as an HEV (Hybrid electric Vehicle) or an EV (electric Vehicle) is equipped with a battery unit that houses a battery (high-voltage battery) for driving a motor. Such a vehicle has a cooling structure for cooling the battery, and an air-cooled cooling structure is widely adopted.

For example, a vehicle is known in which a battery unit is disposed under a seat in a vehicle cabin, and a battery is cooled by air introduced into the battery unit from the vehicle cabin (hereinafter, appropriately referred to as cabin air). A dust filter or the like is provided in an intake portion for taking in air in the vehicle interior in order to remove foreign matter and the like. However, in the case where the dust-proof filter is provided, a pressure loss may occur and the cooling efficiency may be lowered.

In recent years, a grid-shaped intake grill is disposed in the intake portion to remove foreign matter and the like (see, for example, patent document 1).

Effects of the invention

According to the means described in (1), the flow rate of the air taken into the intake grill can be adjusted. That is, since the flow of air becomes faster in the region close to the intake port and becomes slower in the region away from the intake port, the total opening area of the ventilation portion located in the region away from the intake port is made larger than the total opening area of the ventilation portion located in the region close to the intake port, and the flow velocity of air taken into the intake grille can be averaged in the vehicle width direction.

According to the aspect described in (2), since the intake grill and the intake port are offset in the vehicle width direction, it is possible to prevent foreign matter entering from the intake grill from entering the intake port, and to guide air taken in from the intake grill to the intake port.

According to the aspect described in (3), since the flow of air becomes faster in the region on the intake port side and slower in the region on the opposite side to the intake port, the total sum of the opening areas of the ventilation portions in the region on the opposite side to the intake port is made larger than the total sum of the opening areas of the ventilation portions in the region on the intake port side, and the flow velocity of the air taken into the intake grille can be equalized in the vehicle width direction.

According to the aspect described in (4), since the flow of air becomes faster in the region on the intake port side and slower in the region on the opposite side from the intake port, the total opening area of the ventilation portion located in the central region is made smaller than the total opening area of the ventilation portion located in the region on the opposite side from the intake port and larger than the total opening area of the flow rate adjustment window in the region on the intake port side, and the flow velocity of air taken into the intake grille can be equalized in the vehicle width direction.

According to the aspect described in (5), since the intake grill opens toward the front or the rear of the vehicle, it is possible to prevent foreign matter from entering from above when an occupant drops an object.

According to the aspect described in (6), since the intake grille is disposed at the foot side of the occupant, the sense of discomfort given to the occupant by the intake air can be reduced as compared with the case where the intake grille is disposed at the upper side of the seat.

According to the aspect described in (7), since the intake grill is disposed in the upward bent portion at the center of the rear seat that is less frequently used, it is possible to reduce the frequency at which the intake grill is closed and dust is rolled up from the side of the passenger's foot.

According to the means described in (8), even when water droplets enter the intake passage or dew condensation occurs in the intake passage, the water droplets and the dew condensation can be prevented from entering the intake port.

An intake grill 40 for taking in air in the vehicle interior is provided in the kick portion 33 so as to open forward, and the kick portion 33 is positioned above the center tunnel 34 and below the center of the rear seat 10. As shown in fig. 3, the intake grill 40 is mounted to the intake passage 50 that guides the cabin air toward the battery unit 20 by means of a sealing member 54.

[ Battery cell ]

In the battery unit 20, a battery as the electrical device D, a cooling mechanism for cooling the electrical device D, and the like are housed inside the case 21. The electric device D is not limited to a battery, and may be a DC/DC converter, an inverter, or the like, or a combination thereof. The cooling mechanism includes a cooling fan that sucks in the vehicle interior air. The cooling fan may be disposed upstream of the electrical device D or may be disposed downstream of the electrical device D.

The housing 21 is a resin member having a horizontally long substantially rectangular parallelepiped shape and an upward opening, and includes a box-shaped housing main body 22 opening upward and a cover member 23 closing the opening of the housing main body 22, and the cover member 23 supports the seat front side (the front side with respect to the hip) of the rear seat 10 on the upper surface thereof.

An intake port 25 into which an extended portion 51 of the intake duct 50 enters on the left side in the vehicle width direction is provided in the front wall portion 24 of the cover member 23.

[ intake air passage ]

In the intake duct 50, an extension portion 51 is provided to enter the intake port 25 provided in the front wall portion 24 of the cover member 23 from the intake grill 40 provided at the vehicle width direction center of the vehicle V, and the extension portion 51 extends rearward from the vehicle width direction center toward the vehicle width direction left side along the front wall portion 24 of the housing main body 22. That is, the intake grill 40 is provided on one side (the center in the vehicle width direction) of the intake duct 50, the intake port 25 of the battery unit 20 is provided on the other side (the left side in the vehicle width direction) of the intake duct 50, and the intake grill 40 and the intake port 25 are disposed offset in the vehicle width direction.

The intake passage 52 of the intake passage 50 may be inclined upward from the intake grill 40 toward the intake port 25.

As shown by arrows in fig. 2 and 3, the vehicle interior air taken into the intake duct 50 from the intake grille 40 flows along the front wall portion 24 of the cover member 23 from the center in the vehicle width direction toward the left side in the vehicle width direction, and is sent from the extended portion 51 toward the electrical device D located below, the extended portion 51 entering the interior of the housing 21 from the intake port 25.

[ air-intake grille ]

Next, the intake grill 40 will be described in detail with reference to fig. 3 to 5.

The intake grille 40 includes: a rectangular frame 41, the upper two corners of which are cut away; a plurality of first grid forming parts 42 and a plurality of second grid forming parts 43 arranged in a grid shape inside the frame body 41; and a flow rate adjustment plate 44 disposed inside the housing 41 so as to be orthogonal to the first grill forming portion 42 and the second grill forming portion 43. The frame 41, the first grill forming portion 42, the second grill forming portion 43, and the flow rate adjusting plate 44 are preferably integrally formed by injection molding or the like.

The first grill forming portion 42 is a plate-like body that is long in the vertical direction and has a predetermined width in the front-rear direction, and a plurality of first grill forming portions are provided at equal intervals along the vehicle width direction. On the other hand, the second grill forming portion 43 is a plate-like body that is long in the left-right direction and has a predetermined width in the front-rear direction, and a plurality of the second grill forming portions are provided at equal intervals along the up-down direction. The first grid forming part 42 and the second grid forming part 43 are arranged in a grid shape by being orthogonal to each other when viewed from the front-rear direction, and a plurality of rectangular openings 45 are formed.

The flow rate adjustment plate 44 is a plate-shaped body extending in the left-right direction and the up-down direction, and when the vehicle compartment side is set as the front surface of the intake grille 40, the flow rate adjustment plate 44 is connected to the first grille-forming portion 42 and the second grille-forming portion 43 on the rear surface side of the intake grille 40, and has a flow rate adjustment window 46 having an opening area smaller than that of the opening 45 in the entire opening 45 or a part of the opening 45. In the local intake grill 40, the opening area of the opening 45 and the opening area of the flow rate adjustment window 46 may be the same. In fig. 4, the flow adjustment window 46 is represented by dots.

As described above, since the intake grill 40 and the intake port 25 are arranged offset in the vehicle width direction, when the flow rate adjustment windows 46 are arranged uniformly in the vehicle width direction of the entire intake grill 40, the flow velocity of the vehicle interior air taken into the intake grill 40 becomes faster on the intake port 25 side (the left side of the vehicle V in the present embodiment, the right side in fig. 4) and becomes slower as the vehicle moves away from the intake port 25 in the vehicle width direction.

In order to eliminate such variation in the flow velocity, when the intake grille 40 is divided into a region close to the intake port 25 and a region distant from the intake port 25 in the vehicle width direction, the sum total of the opening areas of the flow rate adjustment windows 46 located in the region distant from the intake port 25 is larger than the sum total of the opening areas of the flow rate adjustment windows 46 located in the region close to the intake port 25. More specifically, when the intake grill 40 is divided into two regions P1, P2 by the center O in the vehicle width direction, the sum of the opening areas of the flow rate adjustment windows 46 in the region P1 located on the opposite side from the intake port 25 is larger than the sum of the opening areas of the flow rate adjustment windows 46 in the region P2 located on the intake port 25 side.

By changing the opening area of the flow rate adjustment window 46 in accordance with the position of the intake port 25 in this way, it is possible to adjust the variation in the flow velocity of the vehicle interior air taken into the intake grill 40 in the vehicle width direction, and to equalize the flow velocity of the air taken into the intake grill 40.

Further, when the intake grill 40 is divided into three regions Q1 to Q3 in the vehicle width direction, the sum of the opening areas of the flow rate adjustment windows 46 located in the central region Q2 is smaller than the sum of the opening areas of the flow rate adjustment windows 46 located in the region Q1 located on the side opposite to the intake port 25 and is larger than the sum of the opening areas of the flow rate adjustment windows 46 located in the region Q3 located on the side of the intake port 25. In the example of fig. 4, the opening area of the flow rate adjustment windows 46 decreases in order from the region Q1 toward the region Q3, and the number of the flow rate adjustment windows 46 decreases toward the intake port 25 side in the region Q3.

By appropriately changing the total opening area of the flow rate adjustment window 46 in this way, for example, the flow velocity of air taken in at the center of the intake grille 40 in the vehicle width direction can be made faster than the flow velocity of air taken in at the left and right sides of the intake grille 40 in the vehicle width direction. Conversely, the flow velocity of the air taken in to the left and right sides of the intake grill 40 in the vehicle width direction can be made slower than the flow velocity of the air taken in to the center of the intake grill 40 in the vehicle width direction.

In general, in the rear seats 10, the left and right rear seats 10 are frequently used and the center rear seat 10 is frequently used, so that the flow rate of air taken into the intake grill 40 is slow on the left and right of the rear seat 10 frequently used, compared to the center of the rear seat 10 frequently used. Therefore, the discomfort given to the occupant seated in the rear seat 10 can be further reduced.

As shown in fig. 5, in the opening 45 provided with the flow rate adjustment window 46, the vehicle interior air taken into the intake grille 40 flows from the opening 45 to the intake passage 50 through the flow rate adjustment window 46. At this time, since the opening area of the flow rate adjustment window 46 is smaller than the opening area of the opening portion 45, the flow velocity becomes small on the vehicle compartment side of the opening portion 45, and the flow velocity becomes large at the flow rate adjustment window 46.

When the opening area of the opening 45 on the vehicle compartment side is a1, the wind speed of the air flowing through the opening 45 on the vehicle compartment side is V1, the opening area of the flow rate adjustment window 46 is a2, and the wind speed of the air flowing through the flow rate adjustment window 46 is V2, the amount of wind on the vehicle compartment side of the opening 45 and the opposite side thereof is the same, and therefore a1 · V1 is established as a2 · V2. The opening area a2 of the flow rate adjustment window 46 is smaller than the opening area a1 of the opening portion 45, that is, V1 < V2 is derived from a2< a1, and the flow velocity V1 at the vehicle compartment side of the opening portion 45 becomes smaller than the flow velocity V2 at the flow rate adjustment window 46. Therefore, the vibration characteristics around the intake grill 40 are improved, and the discomfort given to the occupant can be further reduced.

[ conclusion ]

As described above, according to the present embodiment, when the air grille 40 is divided into the region close to the air intake port 25 and the region distant from the air intake port 25 in the vehicle width direction, the total sum of the opening areas of the flow rate adjustment windows 46 located in the region distant from the air intake port 25 is larger than the total sum of the opening areas of the flow rate adjustment windows 46 located in the region close to the air intake port 25, and therefore the flow velocity of the air taken into the air grille 40 can be adjusted. That is, since the flow of air becomes faster in the region close to the intake port 25 and becomes slower in the region away from the intake port 25, the total sum of the opening areas of the flow rate adjustment windows 46 in the region away from the intake port 25 is made larger than the total sum of the opening areas of the flow rate adjustment windows 46 in the region close to the intake port, and the flow velocity of the air taken into the intake grille 40 can be averaged in the vehicle width direction.

Further, since the intake grill 40 and the intake port 25 are offset in the vehicle width direction, it is possible to guide the air taken in from the intake grill 40 to the intake port 25 while preventing foreign matter entering from the intake grill 40 from entering the intake port 25.

In addition, in the case where the air intake grill 40 and the intake port 25 are offset in the vehicle width direction, the flow of air is fast in the region P2 on the intake port 25 side, and the flow of air is slow in the region P1 on the opposite side of the intake port 25, so the flow velocity of air taken into the air intake grill 40 can be averaged in the vehicle width direction by making the total sum of the opening areas of the flow rate adjustment windows 46 in the region P1 on the opposite side of the intake port 25 larger than the total sum of the opening areas of the flow rate adjustment windows 46 in the region P2 on the intake port 25 side.

In addition, when the intake grill 40 is disposed below the center of the rear seat 10, the sum of the opening areas of the flow rate adjustment windows 46 located in the central region Q2 is smaller than the sum of the opening areas of the flow rate adjustment windows 46 located in the region Q1 located on the side opposite to the intake port 25 and is larger than the sum of the opening areas of the flow rate adjustment windows 46 located in the region Q3 located on the side of the intake port 25, so that the flow rate of air taken into the intake grill 40 on the left and right of the rear seat 10 that is frequently used can be made slower than the flow rate of air taken into the intake grill 40 at the center of the rear seat 10 that is less frequently used, and discomfort given to an occupant seated in the rear seat 10 can be further reduced.

In addition, since the intake grill 40 opens toward the front of the vehicle, it is possible to prevent foreign matter from entering from above when an occupant drops an object. The intake grill 40 may be opened toward the rear of the vehicle.

Further, since the intake grill 40 is disposed at the kick portion 33, that is, at the foot of the occupant, it is possible to reduce the discomfort given to the occupant by the intake air as compared with the case where the intake grill 40 is disposed above the seat.

Further, since the step 53 is provided in the intake passage 52 of the intake duct 50 so as to extend upward from the intake grill 40 toward the intake port 25, even when water droplets enter the intake duct 50 or condensation occurs in the intake duct 50, the water droplets and condensation can be prevented from entering the intake port 25.

The present invention is not limited to the above-described embodiments and modifications, improvements, and the like can be appropriately made.

For example, the number and shape of the openings 45 and the flow rate adjustment windows 46 can be set arbitrarily.

In the above embodiment, the flow rate adjustment window 46 is used as the ventilation portion, but the flow rate adjustment plate 44 is not essential, and the opening 45 formed by the first grill forming portion 42 and the second grill forming portion 43 may be used as the ventilation portion, and the opening area of the ventilation portion may be adjusted according to the number and size of the openings 45.

It should be noted that the present application is completed based on japanese patent application (japanese patent application 2017-132868) filed on 7/6/2017, the contents of which are incorporated herein by reference.
