また、第２吸気ダクト４３の下流側端部の上側壁面４３Ａには凸状湾曲面４４が形成されている。凸状湾曲面４４は、第２吸気ダクト４３の上方に向って突出する湾曲形状をなしており、内部ダクト５０の上側部に接続している。   A convex curved surface 44 is formed on the upper wall surface 43 </ b> A at the downstream end of the second intake duct 43. The convex curved surface 44 has a curved shape protruding upward from the second intake duct 43, and is connected to the upper portion of the internal duct 50.

第１冷却風導入口５４は、第２冷却風導入口５６よりも凸状湾曲面４４側に近接して配置されている。また、第１冷却風導入口５４の開口面積は、第２冷却風導入口５６の開口面積よりも小さく設定されている。   The first cooling air introduction port 54 is disposed closer to the convex curved surface 44 side than the second cooling air introduction port 56. The opening area of the first cooling air introduction port 54 is set smaller than the opening area of the second cooling air introduction port 56.

第２吸気ダクト４３は傾斜部４６を有しており、この傾斜部４６は、吸気ファン２０から第２冷却風導入口５６に向って下り勾配で傾斜している。また、第２吸気ダクト４３は水平部４７を有しており、この水平部４７は、傾斜部４６の下端部から第１冷却風導入口５４および第２冷却風導入口５６との上方側まで水平方向に延伸している。   The second intake duct 43 has an inclined portion 46, and the inclined portion 46 is inclined downwardly from the intake fan 20 toward the second cooling air introduction port 56.

Stretched horizontally.

水平部４７と傾斜部４６とが交差する部位の上面には、凹状湾曲面４５が形成されており、この凹状湾曲面４５は、下方側に向って凸状となるように湾曲している。   A concave curved surface 45 is formed on the upper surface of the portion where the horizontal portion 47 and the inclined portion 46 intersect, and the concave curved surface 45 is curved so as to be convex downward.

ここで、凸状湾曲面４４は、冷却風の流れ方向を急激に下向きに変化させるような小さな曲率半径を有している。一方、凹状湾曲面４５の曲率半径は、凸状湾曲面４４の曲率半径よりも大きく設定されている。このため、空気が凹状湾曲面４５に沿って流れることができ、凹状湾曲面４５から空気が剥離することが防止される。   Here, the convex curved surface 44 has a small radius of curvature that rapidly changes the flow direction of the cooling air downward. On the other hand, the radius of curvature of the concave curved surface 45 is set larger than the radius of curvature of the convex curved surface 44. For this reason, air can flow along the concave curved surface 45, and air is prevented from peeling off from the concave curved surface 45.

次に、作用を説明する。本実施例の空気取り込み構造は、車体２の車体フレーム７におけるラゲッジルーム５側の面に装着され、内部空間６１をその内部に形成するトリム６０を備えている。   Next, the operation will be described. The air intake structure of this embodiment includes a trim 60 that is attached to the surface of the body frame 7 of the vehicle body 2 on the side of the luggage room 5 and that forms an internal space 61 therein.

そして、トリム６０は、内部空間６１に空気を吸気するトリム吸気口６３、６４、６５と、内部空間６１の空気を排出するトリム排気口６２と、を有し、トリム排気口６２とダクト吸気口４０Ａとが接続されている。   The trim 60 includes trim inlets 63, 64, 65 for taking air into the internal space 61, and a trim exhaust port 62 for discharging air from the internal space 61. 40A is connected.

これにより、トリム６０のトリム吸気口６３、６４、６５から内部空間６１に導入された空気が、吸気ダクト４０に取り込まれる。このため、吸気ダクト４０内で吸気ファン２０から発生する機械音、またはトリム６０内から吸気ダクト４０に空気を取り込む際の風切り音、等のノイズが、トリム６０の内部空間６１で反射して減衰する。したがって、吸気ダクト４０の内部で発生する吸気ファン２０の機械音や風切り音等のノイズがラゲッジルーム５内に漏れることを抑制できる。   Thereby, the air introduced into the internal space 61 from the trim intake ports 63, 64, 65 of the trim 60 is taken into the intake duct 40. Therefore, noise such as mechanical noise generated from the intake fan 20 in the intake duct 40 or wind noise when air is taken into the intake duct 40 from the trim 60 is reflected by the internal space 61 of the trim 60 and attenuated. To do. Therefore, it is possible to suppress noise such as mechanical noise and wind noise from the intake fan 20 generated inside the intake duct 40 from leaking into the luggage room 5.

また、本実施例の空気取り込み構造において、トリム吸気口６３、６４、６５の面積が、ダクト吸気口４０Ａの面積よりも大きい。   Further, in the air intake structure of the present embodiment, the area of the trim intake ports 63, 64, 65 is larger than the area of the duct intake port 40A.

これにより、トリム吸気口６３、６４、６５を通過する空気の流速が、ダクト吸気口４０Ａを通過する空気の流速より遅くなる。このため、ダクト吸気口４０Ａをトリム排気口６２に接続せずにラゲッジルーム５内またはラゲッジルーム５外に露出した場合と比較して、空気をトリム６０の内部空間６１に取り込むときの風切り音を抑制できる。   Thereby, the flow velocity of the air passing through the trim intake ports 63, 64, 65 is slower than the flow velocity of the air passing through the duct intake port 40A. For this reason, compared with the case where the duct intake port 40A is not connected to the trim exhaust port 62 and is exposed outside the luggage room 5 or outside the luggage room 5, the wind noise when the air is taken into the internal space 61 of the trim 60 is reduced. Can be suppressed.

また、本実施例の空気取り込み構造において、トリム吸気口６３、６４、６５は、トリム６０における互いに異なる部位に分割して配置されている   Further, in the air intake structure of the present embodiment, the trim intake ports 63, 64, 65 are divided and arranged at different portions in the trim 60.

これにより、トリム６０が複数のトリム吸気口６３、６４、６５を有するため、複数のトリム吸気口６３、６４、６５のうち何れかのトリム吸気口が障害物等で遮蔽された場合に、残りのトリム吸気口から空気を吸気できる。   Thus, since the trim 60 has a plurality of trim inlets 63, 64, 65, when any one of the plurality of trim inlets 63, 64, 65 is shielded by an obstacle or the like, it remains. Air can be drawn from the trim inlet.

また、複数のトリム吸気口６３、６４、６５が、トリム６０における互いに異なる部位にそれぞれ配置されているため、トリム６０内に空気を吸気する際の風切り音の発生部位を分散することができ、風切り音を小さくすることができる。   Further, since the plurality of trim inlets 63, 64, 65 are arranged in different parts of the trim 60, wind noise generation parts when air is sucked into the trim 60 can be dispersed, Wind noise can be reduced.

また、本実施例の空気取り込み構造において、トリム６０は、車室の内壁面を形成するサイドトリムであり、ダクト排気口４０Ｂの下流側に、空気が供給される電装品としてバッテリパック１０が配置されている。   Further, in the air intake structure of the present embodiment, the trim 60 is a side trim that forms the inner wall surface of the passenger compartment, and the battery pack 10 is disposed as an electrical component to which air is supplied on the downstream side of the duct exhaust port 40B. Has been.

これにより、空気取り込み構造を電装品の冷却構造に用いているため、図示しない天面側のトリムと比較して太陽光の照射量が少ないサイドトリムとしてのトリム６０から空気を取り込んでいるので、取り込む空気の温度が太陽光の照射により上昇することを抑制できる。   Thereby, since the air intake structure is used for the cooling structure of the electrical component, air is taken in from the trim 60 as a side trim with a small amount of sunlight irradiation compared to the trim on the top surface (not shown). It can suppress that the temperature of the air taken in rises by irradiation of sunlight.

また、本実施例の空気取り込み構造において、トリム６０は、車室の一部であるラゲッジルーム５の内壁面を形成し、電装品としてのバッテリパック１０がラゲッジルーム５に配置されている。   In the air intake structure of the present embodiment, the trim 60 forms the inner wall surface of the luggage room 5 that is a part of the passenger compartment, and the battery pack 10 as an electrical component is disposed in the luggage room 5.

このように、トリム６０は、開閉されるドアの内壁面を形成するドアトリムではなく、ラゲッジルームの内壁面を形成するサイドトリムである。これにより、吸気ダクト４０とトリム６０とを常時接続することができる。   Thus, the trim 60 is not a door trim that forms the inner wall surface of the door that is opened and closed, but a side trim that forms the inner wall surface of the luggage room. Thereby, the intake duct 40 and the trim 60 can always be connected.

また、バッテリパック１０がラゲッジルーム５に配置されているため、トリム６０とバッテリパック１０との距離を短くでき、吸気ダクト４０の長さも短くできるため、吸気ダクト４０内での圧力損失を低減できる。   Further, since the battery pack 10 is disposed in the luggage room 5, the distance between the trim 60 and the battery pack 10 can be shortened, and the length of the intake duct 40 can be shortened, so that the pressure loss in the intake duct 40 can be reduced. .

なお、図４に示すように、内部空間６１がトリム６０のみによって完全に覆われるように、トリム６０を袋状に形成してもよい。   As shown in FIG. 4, the trim 60 may be formed in a bag shape so that the internal space 61 is completely covered only by the trim 60.

また、図５に示すように、トリム６０の内部空間６１が車体フレーム７の内部に連通するように開口部６６を形成し、この開口部６６を開閉するバルブ６７を設けてもよい。図５において、バルブ６７は開状態となっており、この開状態では、車体フレーム７の内部の空気が開口部６６を介して内部空間６１へ取り込まれている。また、バルブ６７が開状態のとき、このバルブ６７は、トリム吸気口６３から内部空間６１へ至る空気の経路を閉じている。このように、バルブ６７は、車体フレーム７の内部から内部空間６１に空気を取り込む位置と、トリム吸気口６３から内部空間６１へ空気を取り込む位置と、の間で揺動可能に構成されている。バルブ６７は、車両１に搭載された図示しない制御部およびアクチュエータにより開閉される。バルブ６７は手動操作によって開閉可能に構成されていてもよい。   Further, as shown in FIG. 5, an opening 66 may be formed so that the internal space 61 of the trim 60 communicates with the inside of the vehicle body frame 7, and a valve 67 for opening and closing the opening 66 may be provided. In FIG. 5, the valve 67 is in an open state, and in this open state, air inside the vehicle body frame 7 is taken into the internal space 61 through the opening 66. When the valve 67 is open, the valve 67 closes the air path from the trim air inlet 63 to the internal space 61. As described above, the valve 67 is configured to be swingable between a position where air is taken into the internal space 61 from the inside of the vehicle body frame 7 and a position where air is taken into the internal space 61 from the trim intake port 63. . The valve 67 is opened and closed by a control unit and an actuator (not shown) mounted on the vehicle 1. The valve 67 may be configured to be opened and closed by manual operation.

また、車体フレーム７の内部は、車両外部と連通しても良い。   Further, the inside of the body frame 7 may communicate with the outside of the vehicle.

また、室内の内気温度を検出する内気温度センサと、車体フレーム７の内部または外気温度を検出する外気温度センサを設け、内気温度センサおよび外気温度センサの検出結果に応じて、バルブ６７を開閉すれば、取り込み空気の温度を調節できる。   Further, an inside air temperature sensor for detecting the inside air temperature in the room and an outside air temperature sensor for detecting the inside or outside air temperature of the body frame 7 are provided, and the valve 67 is opened and closed according to the detection results of the inside air temperature sensor and the outside air temperature sensor. If so, the temperature of the intake air can be adjusted.
