Description

Vehicle with a steering wheel

Technical Field

The present disclosure relates to vehicles.

Background

For example, japanese patent application laid-open No. 2015-8585859 discloses a battery cooling structure for cooling a battery mounted on a vehicle. The battery cooling structure includes a battery pack, a blower for sending cooling air to the battery pack, and an air intake duct connected to an air intake side of the blower. The air suction port of the air suction passage is opened at the lower garnish located at the outer edge of the lower space of the seat cushion of the rear seat.

Further, japanese patent application laid-open No. 2008-221988 discloses a vehicle including a floor panel, a rear seat disposed above the floor panel, a battery pack, and an air supply duct disposed between the floor panel and the rear seat for supplying air into the battery pack.

Disclosure of Invention

In the battery cooling structure disclosed in the above-mentioned japanese patent laid-open publication No. 2015-8585859, an intake port of an intake passage for sending air into the battery pack is opened at a garnish provided below a rear seat cushion. However, a seat cover is sometimes fitted to a seat cushion of a vehicle. In such a case, if the seat cover sometimes covers the air intake port of the air intake duct, there is a possibility that air cannot be sufficiently sent into the battery pack.

Accordingly, an object of the present disclosure is to solve the above problems and provide a vehicle that sufficiently ensures cooling performance of a power supply device.

A vehicle according to the present disclosure includes: a power supply device; a seat cushion disposed in the vehicle interior; a garnish disposed below the seat cushion; and a side sill constituting a lower edge of an opening portion for an occupant to ride in the vehicle compartment. The decoration includes: a main body portion having an outer peripheral surface connected to a seat cushion; and a protruding portion provided below the outer peripheral surface and protruding from the main body portion toward the side sill. The vehicle further includes an intake duct including a first intake port opened in an outer peripheral surface and a second intake port opened in the protruding portion, and the intake duct introduces air in the vehicle interior toward the power supply device.

According to the vehicle configured as described above, even if the seat cover may block the first intake port when the seat cushion is equipped with the seat cover, the air introduced into the power supply device can be compensated by the intake air from the second intake port. This can sufficiently ensure the cooling performance of the power supply device.

Further, it is preferable that the protruding portion has a front surface facing the front of the vehicle. The second suction port opens in the front surface.

According to the vehicle configured as described above, since the second intake port opens to the front surface of the protruding portion that faces the front of the vehicle, it is possible to suppress the entry of foreign matter into the intake duct through the second intake port.

Preferably, the vehicle further includes a fan. The suction passage includes: a first duct portion extending from the first air intake port and connected to the fan; and a second pipeline part extending from the second air suction port and connected to the pipeline of the first pipeline part between the first air suction port and the fan.

According to the vehicle configured as described above, the air intake duct can be configured more compactly than in the case where the duct connecting the first air intake port and the fan and the duct connecting the second air intake port and the fan are provided by different paths.

Preferably, the opening area of the first intake port is larger than the opening area of the second intake port.

According to the vehicle thus configured, when the seat cover is not provided so as to close the first intake port, the cooling performance of the power supply device can be ensured mainly by the intake air from the first intake port having a relatively large opening area. On the other hand, in the case where the seat cover is provided so as to partially close the first intake port, the cooling performance of the power supply device can be ensured by compensating for the intake air from the first intake port by the intake air from the second intake port having a relatively small opening area.

The above and other objects, features, aspects and advantages of the present invention will become apparent from the following detailed description of the present invention, which is to be read in connection with the accompanying drawings.

Referring to fig. 3 and 4, the vehicle 10 further includes a garnish 61 and a fender 27.

The garnish 61 is provided below the seat cushion 23. The garnish 61 constitutes an inner lining of the vehicle interior below the seat cushion 23. The garnish 61 is made of a resin plate material. The garnish 61 is provided at a corner between the front portion and the left side portion of the seat cushion 23.

The protector plate 27 is provided so as to cover the side sill 20. The trim 27 is a plate material for protecting or decorating the side sill 20. The fender 27 extends in the vehicle front-rear direction while covering the side sill 20. The guard plate 27 (side sill 20) is provided in parallel with the garnish 61 in the vehicle width direction. The protector plate 27 may be made of resin or metal.

The shield 27 has an upper surface 28. The upper surface 28 faces upward. The upper surface 28 constitutes a tread surface for an occupant who gets into the vehicle compartment through the opening 16.

The seat cushion 23 has a front surface 23f, side surfaces 23m, and an intermediate surface 23 g. The front surface 23f faces the front of the vehicle. The side surface 23m faces the vehicle left direction. The side surface 23m faces the opening surface of the opening portion 16 in the vehicle width direction. The intermediate surface 23g connects the front surface 23f and the side surface 23 m. The intermediate surface 23g extends in the diagonally forward direction of the vehicle from the side surface 23m toward the front surface 23 f. The length from the opening surface of the opening portion 16 to the intermediate surface 23g in the vehicle width direction becomes larger as approaching from the side surface 23m to the front surface 23 f.

The garnish 61 has a main body portion 62 and an extension portion 66. The main body 62 and the extension 66 are integrally molded from resin.

The main body portion 62 is provided directly below the seat cushion 23. The body portion 62 has an outer peripheral surface 63. The outer peripheral surface 63 is disposed parallel to the vertical direction. The outer peripheral surface 63 is connected to the seat cushion 23. The outer peripheral surface 63 is continuous with the front surface 23f, the intermediate surface 23g, and the side surface 23m of the seat cushion 23. The outer peripheral surface 63 is disposed coplanar with the front surface 23f, the middle surface 23g, and the side surfaces 23m of the seat cushion 23.

The outer peripheral surface 63 does not necessarily have to be in a coplanar relationship with the front surface 23f, the intermediate surface 23g, and the side surfaces 23m of the seat cushion 23, and for example, the outer peripheral surface 63 may be positioned further inward than the front surface 23f, the intermediate surface 23g, and the side surfaces 23m of the seat cushion 23.

The protruding portion 66 is provided below the outer peripheral surface 63. The protruding portion 66 protrudes from the main body portion 62 toward the side sill 20 (the apron 27).

The protruding portion 66 is provided between the main body portion 62 and the side sill 20 (the apron 27) in the vehicle width direction so as to fill in a level difference generated in the floor panel 26.

The projection 66 has an upper surface 67 and a front surface 68. The upper surface 67 is arranged parallel to the horizontal direction. The upper surface 67 faces upward. The upper surface 67 is continuous from the lower end of the outer peripheral surface 63. The upper surface 67 is connected to the upper surface 28 of the shield 27. The upper surface 67 is disposed coplanar with the upper surface 28 of the shield 27. The width of the upper surface 67 in the vehicle width direction becomes larger from the vehicle rear toward the vehicle front.

The front surface 68 is disposed parallel to the vertical direction. The front surface 68 faces the front of the vehicle. The front surface 68 faces a space under the feet of an occupant seated in the rear seat 22 in the vehicle front-rear direction. The front surface 68 is provided at a position bent downward from the front end of the upper surface 67. The left end of the front surface 68 is connected to the protector plate 27. The right end of the front surface 68 is continuous with the outer peripheral surface 63 of the main body 62.

The length (lengthwise) of the front surface 68 in the up-down direction is smaller than the length (widthwise) of the front surface 68 in the horizontal direction. The longitudinal length of the front surface 68 is smaller than the longitudinal length of the outer peripheral surface 63.

Referring to fig. 2 to 4, the intake passage 41 has a first intake port 51 and a second intake port 56. The intake passage 41 is opened to the space in the vehicle interior through the first intake port 51 and the second intake port 56.

The first air intake port 51 opens at the outer peripheral surface 63 of the body portion 62. The outer peripheral surface 63 is provided in a lattice shape at a position where the first intake port 51 opens. The opening surface of the first air intake port 51 has a rectangular shape as a whole. The opening face of the first intake port 51 faces in the oblique front direction of the vehicle.

The second suction port 56 opens at the protruding portion 66. The second suction port 56 opens at the front surface 68 of the projection 66. The front surface 68 is provided in a lattice shape at a position where the second suction port 56 opens. The opening surface of the second air inlet 56 has a rectangular shape as a whole. The opening surface of the second air inlet 56 has a rectangular shape whose lateral length is larger than the longitudinal length as a whole. The opening surface of the second intake port 56 faces the vehicle front.

The first intake port 51 is provided below the middle surface 23g of the seat cushion 23. The first air intake port 51 is provided above the upper surface 67 of the protruding portion 66. The second intake port 56 is provided at a position away from the first intake port 51. The second intake port 56 is provided below the first intake port 51. The second air inlet 56 is provided below the upper surface 67 of the protruding portion 66. The second suction opening 56 is provided above the floor 26. The second intake port 56 is provided closer to the side sill 20 (the shroud 27) than the first intake port 51 in the vehicle width direction. The second intake port 56 is provided closer to the vehicle front side than the first intake port 51 in the vehicle front-rear direction.

The opening area of the first intake port 51 is larger than the opening area of the second intake port 56. The longitudinal length of the opening surface of the first intake port 51 is greater than the longitudinal length of the opening surface of the second intake port 56. The lateral length of the opening surface of the first intake port 51 is smaller than the lateral length of the opening surface of the second intake port 56.

A seat cover may be attached to the seat cushion 23 for the purpose of keeping the rear seat 22 clean. In such a case, if the seat cover is not of a proper size or if the seat cover is displaced from the seat cushion 23, the air intake port of the air intake duct is blocked by the seat cover, and thus there is a possibility that air is not sufficiently introduced into the battery pack 31. For example, when the vehicle 10 is a hybrid vehicle, if the amount of air introduced into the battery pack 31 is insufficient, the battery temperature in the battery pack 31 rises. Accordingly, it is assumed that the output of the motor that receives the electric power supply from the battery pack 31 is limited, and the fuel economy of the vehicle 10 is deteriorated.

In contrast, in the present embodiment, the intake passage 41 includes the first intake port 51 and the second intake port 56. The first intake port 51 opens to an outer peripheral surface 63 of a main body portion 62 connected to the seat cushion 23, and the second intake port 56 opens to a protruding portion 66 provided below the outer peripheral surface 63.

With this configuration, even if the seat cover attached to the seat cushion 23 sometimes covers the first intake port 51, the air introduced into the battery pack 31 can be compensated by the intake air from the second intake port 56. This can sufficiently ensure the cooling performance of the battery pack 31. As a result, when the vehicle 10 is a hybrid vehicle, the output limit of the electric motor can be suppressed to maintain the fuel efficiency of the vehicle 10.

In the present embodiment, the opening area of the first intake port 51 is larger than the opening area of the second intake port 56.

With such a structure, in the case where the seat cover is not provided so as to close the first intake port 51, the cooling performance of the battery pack 31 can be ensured mainly by the intake air from the first intake port 51 having a relatively large opening area. On the other hand, in the case where the seat cover is provided so as to partially block the first intake port 51, the cooling performance of the battery pack 31 can be ensured by compensating for the intake air from the first intake port 51 by the intake air from the second intake port 56 having a relatively small opening area.

In addition, in the present embodiment, the second suction port 56 opens at the front surface 68 in the protruding portion 66.

According to such a configuration, since the front surface 68 of the second air inlet 56 opens is directed forward, it is possible to suppress the entry of foreign matter into the air intake duct 41 through the second air inlet 56, compared to the case where the second air inlet 56 opens at the upper surface 67 of the protruding portion 66. In addition, since the second air inlet 56 is not directly stepped on by the occupant, the durability of the garnish 61 is easily maintained.

Fig. 5 is a perspective view showing the garnish and the air intake passage when viewed in the direction indicated by the arrow V in fig. 4. Referring to fig. 2, 4 and 5, the intake passage 41 includes a first duct portion 43, a second duct portion 44 and a third duct portion 45.

The first duct portion 43 extends from the first air intake port 51 and is connected to the fan 42. The second duct portion 44 extends from the second air inlet 56 and is connected to the duct of the first duct portion 43 between the first air inlet 51 and the fan 42. The third duct portion 45 extends from the fan 42 and is connected to the battery pack 31. Third duct portion 45 branches off at the front side extending from fan 42, and is connected to first battery module 33 and second battery module 34.

The fan 42 is disposed at the vehicle rear of the second intake port 56 in the vehicle front-rear direction. The first duct portion 43 extends from the first intake port 51 toward the vehicle rear, and is bent in the vehicle left direction to be connected to the fan 42. The second duct portion 44 extends from the second intake port 56 toward the vehicle rear directly below the upper surface 67 of the projecting portion 66, and is bent upward to be connected to the first duct portion 43.

A filter 46 is provided in the first pipe section 43. The filter 46 removes dust from air introduced into the battery pack 31. The second pipe section 44 is connected to the pipe of the first pipe section 43 between the first suction port 51 and the filter 46. Fig. 5 shows the first pipe section 43 in the section from the first intake port 51 to the filter 46.

In the present embodiment, the intake passage 41 includes the first duct portion 43 extending from the first intake port 51 and connected to the fan 42, and the second duct portion 44 extending from the second intake port 56 and connected to the duct of the first duct portion 43 between the first intake port 51 and the fan 42. With such a configuration, the intake duct 41 can be configured more compactly than in the case where the duct connecting the first intake port 51 and the fan 42 and the duct connecting the second intake port 56 and the fan 42 are provided by different paths.

Although the structures of the seat cushion 23, the garnish 61, and the intake duct 41(41L) on the vehicle left side have been described above, the seat cushion 23, the garnish 61, and the intake duct 41(41R) on the vehicle right side also have the same structure that is bilaterally symmetrical.

Note that, not limited to the above, either one of the intake passage 41L and the intake passage 41R may have the first intake port 51 and the second intake port 56, and the other of the intake passage 41L and the intake passage 41R may have only the first intake port 51.

The vehicle 10 in the present embodiment includes a battery pack 31 as a power supply device, a seat cushion 23 provided in a vehicle interior, a garnish 61 provided below the seat cushion 23, and a side sill 20 constituting a lower edge of an opening portion 16 for an occupant to ride in the vehicle interior. The garnish 61 includes a main body portion 62 having an outer peripheral surface 63 connected to the seat cushion 23, and a protruding portion 66 provided below the outer peripheral surface 63 and protruding from the main body portion 62 toward the side sill 20. The vehicle 10 further includes an intake duct 41, and the intake duct 41 includes a first intake port 51 opened in an outer peripheral surface 63 and a second intake port 56 opened in a protruding portion 66, and introduces air in the vehicle interior toward the battery pack 31.

According to such a configuration, even if the seat cover may block the first intake port 51 when the seat cover is attached to the seat cushion 23, the cooling performance of the battery pack 31 can be sufficiently ensured by the intake air from the second intake port 56.

The power supply device in the present disclosure is not limited to a power storage device using a battery, and may be a power storage device using a capacitor, for example. In addition, the power supply device in the present disclosure may also be a fuel cell. In this case, the vehicle in the present disclosure may also be a fuel cell automobile. In addition, the seat cushion in the present disclosure is typically a seat cushion of a rear seat, but is not limited thereto.

The present disclosure is applied to, for example, a hybrid vehicle or an electric vehicle.

While the embodiments of the present invention have been described, the embodiments disclosed herein are to be considered in all respects as illustrative and not restrictive.
