In each figure, the arrow FR indicates the vehicle body front direction, the arrow RE indicates the vehicle body rear direction, the arrow UP indicates the vehicle body upward direction, the arrow IN indicates the vehicle body inner direction, and the arrow OUT indicates the vehicle body outer direction.

図１〜図３には、本発明の実施形態に係る車体前部の導風構造が示されている。図１に示すように、車体前部の導風構造１０は、車体１１、フロントバンパ２７に設けられた移動手段２８、移動手段２８で車体上下方向に移動可能に支持される板状部材１２、車体１１の前端部下側に設けられ、走行風１８をエンジンルーム１３に導入するラジエータ取風口１４、ラジエータ取風口１４の車幅方向両脇に設けられ、走行風１９を図示しないフロントブレーキ近傍に導入するブレーキ取風口１６から構成されている。   1 to 3 show a wind guide structure for a front portion of a vehicle body according to an embodiment of the present invention. As shown in FIG. 1, the wind guide structure 10 at the front of the vehicle body includes a vehicle body 11, a moving means 28 provided on the front bumper 27, a plate-like member 12 supported by the moving means 28 so as to be movable in the vertical direction of the vehicle body, Provided below the front end of the vehicle body 11 and provided on both sides in the vehicle width direction of the radiator air inlet 14 and the radiator air inlet 14 for introducing the traveling air 18 into the engine room 13. It is comprised from the brake air inlet 16 which carries out.

図２に示すように、フロントバンパ２７には移動手段２８が設けられ、板状部材１２を車体上下方向に移動可能に支持している。移動手段２８は例えばモータにラックギアとピニオンギアを組み合わせた往復運動装置でも、あるいはギアで駆動されるタイミングベルト上に固定された移動ステージでもよく、または油圧装置を用いたアクチュエータでも、電磁石とスプリングを用いた駆動機構などでもよい。   As shown in FIG. 2, the front bumper 27 is provided with a moving means 28, and supports the plate member 12 so as to be movable in the vertical direction of the vehicle body. The moving means 28 may be, for example, a reciprocating motion device in which a rack gear and a pinion gear are combined with a motor, a moving stage fixed on a timing belt driven by a gear, or an actuator using a hydraulic device, and an electromagnet and a spring. The drive mechanism used may be used.

図２（Ａ）、図３（Ａ）に示すように、板状部材１２が高い位置にあり、車体前方視でラジエータ取風口１４に重ならないとき、車体前方からの走行風１８はエンジンルーム１３に導入される。エンジンルーム１３に導入された走行風１８はコンデンサ２０、ラジエータ２２等に吹き付けられる。   As shown in FIGS. 2A and 3A, when the plate-like member 12 is at a high position and does not overlap the radiator air inlet 14 when viewed from the front of the vehicle body, the traveling wind 18 from the front of the vehicle body is generated in the engine room 13.

図２（Ｂ）、図３（Ｂ）に示すように、板状部材１２が低い位置にあり、車体前方視でラジエータ取風口１４に重なるとき、車体前方からの走行風１８は板状部材１２により堰き止められ、高圧部分２４が形成され、その結果としてエンジンルーム１３へ導入される走行風１８の風量は減少する。   As shown in FIGS. 2 (B) and 3 (B), when the plate-like member 12 is in a low position and overlaps with the radiator air inlet 14 when viewed from the front of the vehicle body, the traveling wind 18 from the front of the vehicle body becomes the plate-like member 12. As a result, the air volume of the traveling wind 18 introduced into the engine room 13 is reduced.

また図３に示すように、ブレーキ取風口１６には走行風１９が導入される。図３（Ｂ）に示すように、板状部材１２が低い位置にあるときは、ラジエータ取風口１４に導入されなかった走行風１８の一部がブレーキ取風口１６に導入される。   As shown in FIG. 3, traveling wind 19 is introduced into the brake air intake 16.

＜作用効果＞
次に本発明の実施形態の作用および効果について説明する。 <Effect>
Next, operations and effects of the embodiment of the present invention will be described.

図２には本発明の実施形態に係る車体前部の導風構造の動作を示す断面図が、図３には平面図と正面図が示されている。   2 is a cross-sectional view showing the operation of the wind guide structure at the front of the vehicle body according to the embodiment of the present invention, and FIG. 3 is a plan view and a front view.

図２（Ａ）に示すように、走行中の車体１１において板状部材１２が車体上方にあり、ラジエータ取風口１４と正面視で重なっていないとき、すなわち車体前方からの走行風１８の、ラジエータ取風口１４への流入を妨げない位置にある場合は、図３（Ａ）に示されるように走行風１８はラジエータ取風口１４へ、また走行風１９はラジエータ取風口１４の車幅方向両脇に設けられたブレーキ取風口１６へ導入される。   As shown in FIG. 2A, when the plate-like member 12 is above the vehicle body in the traveling vehicle body 11 and does not overlap the radiator air inlet 14 in front view, that is, the radiator of the traveling wind 18 from the front of the vehicle body. When it is in a position that does not hinder the inflow to the air intake 14, as shown in FIG. 3A, the traveling air 18 is directed to the radiator air intake 14, and the traveling air 19 is located on both sides of the radiator air intake 14 in the vehicle width direction. Is introduced into the brake air intake 16 provided in the vehicle.

このときエンジンルーム１３内に設けられたラジエータ２２には走行風１８が十分に吹き付けられるので、ラジエータ２２のエンジン冷却能力は最も効率よく発揮され、通常走行時すなわち定常速度での走行に適した状態となる。   At this time, since the running wind 18 is sufficiently blown to the radiator 22 provided in the engine room 13, the engine cooling capacity of the radiator 22 is most efficiently exhibited, and is a state suitable for running at normal speed, that is, at steady speed. It becomes.

ここで乗員がブレーキを踏むことにより車体１１が減速すると、図示しない保持部材で車体上下方向に移動可能に支持された板状部材１２は、図２（Ｂ）に示すように車体下方へ移動し、ラジエータ取風口１４を閉塞する。   Here, when the vehicle body 11 decelerates when the occupant steps on the brake, the plate-like member 12 supported so as to be movable in the vertical direction of the vehicle body by a holding member (not shown) moves downward as shown in FIG. The radiator air inlet 14 is closed.

これにより車体前方からの走行風１８はラジエータ取風口１４に導入されにくくなり、板状部材１２の車体前方には周囲よりも気圧の高い、高圧部分２４が形成され、走行風１８は車体上下方向あるいは車幅方向に流れる。   This makes it difficult for the traveling wind 18 from the front of the vehicle body to be introduced into the radiator air inlet 14, and a high-pressure portion 24 having a higher atmospheric pressure than the surroundings is formed in front of the vehicle body of the plate-like member 12. Or it flows in the vehicle width direction.

このとき図３（Ｂ）に示すように、車幅方向に流れた走行風１８の一部は走行風１９とともにブレーキ取風口１６へ導入される。このためフロントブレーキ３０へ導入される走行風の風量が増加し、フロントブレーキ３０はより強く冷却される。このため車体１１を制動するブレーキの性能は効率よく発揮される。   At this time, as shown in FIG. 3B, a part of the traveling wind 18 flowing in the vehicle width direction is introduced into the brake air intake 16 together with the traveling wind 19. For this reason, the amount of traveling wind introduced into the front brake 30 increases, and the front brake 30 is cooled more strongly. Therefore, the performance of the brake that brakes the vehicle body 11 is efficiently exhibited.

さらに、エンジンルーム１３への走行風１８の流入量が減少することで、車体前方のダウンフォースなど、車体１１の車体前側の空力性能が向上し、操縦安定性を向上させることができる。   Furthermore, since the inflow amount of the traveling wind 18 into the engine room 13 is reduced, the aerodynamic performance on the front side of the vehicle body 11 such as the downforce in front of the vehicle body is improved, and the steering stability can be improved.

図４〜図９には、本発明の実施形態に係る車体前部の導風構造の動作制御を示すフロー図が示されている。   4 to 9 are flowcharts showing the operation control of the wind guide structure at the front part of the vehicle body according to the embodiment of the present invention.

車速をＶ、ブレーキ踏力をβ、ラジエータ水温をｔとし、それぞれ所定の閾値をＶ１、β１、ｔ１としたとき、車体１１の空力性能、ブレーキ冷却、エンジン冷却についての優先順位によって、板状部材１２の位置を上（ラジエータ取風口１４を開放）、下（ラジエータ取風口１４を閉塞）のどちらとするかの制御フローが複数種類考えられる。図示しない車速センサ、ブレーキスイッチおよびラジエータ温度計により検出される車速Ｖ、ブレーキ踏力β、ラジエータ温度ｔより、空力性能、ブレーキ冷却、エンジン冷却の何れを優先させるかに従って図示しない制御装置が移動手段２８を制御し、板状部材１２の位置決定を行う。   When the vehicle speed is V, the brake pedaling force is β, the radiator water temperature is t, and the predetermined threshold values are V1, β1, and t1, respectively, the plate-like member 12 depends on the aerodynamic performance of the vehicle body 11, brake cooling, and engine cooling. A plurality of types of control flows can be conceived to determine whether the position is up (the radiator air inlet 14 is opened) or lower (the radiator air inlet 14 is closed). A control device (not shown) moves according to whether aerodynamic performance, brake cooling or engine cooling is prioritized over vehicle speed V, brake pedal force β, and radiator temperature t detected by a vehicle speed sensor, brake switch and radiator thermometer (not shown). To determine the position of the plate-like member 12.

すなわち図４に示すように、空力性能、ブレーキ冷却、エンジン冷却の順に優先する制御としたときは、まず車速Ｖが閾値Ｖ１より速ければ定常速度での運転中と判断し、車体の空力性能が優先され、制御装置の判断に従い移動手段２８は板状部材１２を下（ラジエータ取風口１４閉じ位置）に位置させる。   That is, as shown in FIG. 4, when the control is given priority in the order of aerodynamic performance, brake cooling, and engine cooling, first, if the vehicle speed V is higher than the threshold value V1, it is determined that the vehicle is operating at a steady speed, and the aerodynamic performance of the vehicle body is Priority is given, and the moving means 28 positions the plate-like member 12 downward (the radiator air inlet 14 closing position) according to the judgment of the control device.

車速Ｖが閾値Ｖ１より遅ければブレーキ踏力βについて、閾値β１との比較が行われる。ここでブレーキ踏力βが閾値β１より大きければ大きく減速中であり、板状部材１２は下（ラジエータ取風口１４閉じ位置）位置とされ、ブレーキ取風口１６へ走行風１８、１９が導入され、より強くブレーキ冷却が行われることでフロントブレーキ３０の制動能力が向上する。   If the vehicle speed V is slower than the threshold value V1, the brake pedal force β is compared with the threshold value β1. Here, if the brake pedaling force β is larger than the threshold value β1, the vehicle is decelerating greatly, the plate-like member 12 is set at the lower position (the radiator air intake 14 closed position), and the traveling winds 18 and 19 are introduced into the brake air intake 16. The braking ability of the front brake 30 is improved by the strong brake cooling.

ブレーキ踏力βが閾値β１より低い場合、ラジエータ温度ｔについて閾値ｔ１との比較が行われる。ラジエータ温度ｔが閾値ｔ１よりも高い場合はエンジン冷却のため板状部材１２の位置は上位置（ラジエータ取風口１４開き位置）とされ、ラジエータ取風口１４に走行風１８が導入されることでラジエータ２２がより冷却され、よりエンジン温度を下げることができる。   When the brake pedal force β is lower than the threshold value β1, the radiator temperature t is compared with the threshold value t1. When the radiator temperature t is higher than the threshold value t1, the position of the plate-like member 12 is set to the upper position (opening position of the radiator air intake 14) for engine cooling, and the running air 18 is introduced into the radiator air intake 14 to thereby provide the radiator. 22 is cooled more and the engine temperature can be further lowered.

同様に図５に示すように、空力性能、エンジン冷却、ブレーキ冷却の順に優先する制御としたときは、まず車速Ｖが閾値Ｖ１より速ければ定常速度での運転中と判断し、車体の空力性能が優先され板状部材１２は下（ラジエータ取風口１４閉じ位置）となる。次いでラジエータ温度ｔが閾値ｔ１よりも高ければラジエータ２２冷却のため板状部材１２の位置は上（ラジエータ取風口１４開き位置）とされ、更にブレーキ踏力βが閾値β１より高ければブレーキ冷却のため板状部材１２は下（ラジエータ取風口１４閉じ位置）となる。   Similarly, as shown in FIG. 5, when the control is given priority in the order of aerodynamic performance, engine cooling, and brake cooling, first, if the vehicle speed V is higher than the threshold value V1, it is determined that the vehicle is operating at a steady speed, and the aerodynamic performance of the vehicle body is determined. Is given priority, and the plate-like member 12 is located at the lower position (the radiator air inlet 14 is closed). Next, if the radiator temperature t is higher than the threshold value t1, the plate-like member 12 is moved upward for cooling the radiator 22. If the brake pedal force β is higher than the threshold value β1, the plate is used for cooling the brake. The shaped member 12 is at the bottom (position where the radiator air inlet 14 is closed).

以下、同様に図６ではエンジン冷却、空力性能、ブレーキ冷却の順に優先する制御として制御手段が板状部材１２の位置を決定し、図７ではエンジン冷却、ブレーキ冷却、空力性能の順に優先する制御として板状部材１２の位置を決定し、図８ではブレーキ冷却、空力性能、エンジン冷却の順に優先する制御として板状部材１２の位置を決定し、図９ではブレーキ冷却、エンジン冷却、空力性能の順に優先する制御として板状部材１２の位置を決定する場合のフロー図が示されている。   Similarly, in FIG. 6, the control means determines the position of the plate-like member 12 as priority control in order of engine cooling, aerodynamic performance, and brake cooling. In FIG. 7, control priority is given to engine cooling, brake cooling, and aerodynamic performance in this order. The position of the plate-like member 12 is determined as shown in FIG. 8. In FIG. 8, the position of the plate-like member 12 is determined as priority control in the order of brake cooling, aerodynamic performance, and engine cooling. A flow diagram in the case of determining the position of the plate-like member 12 as the priority control is shown.

以上、実施形態を挙げて本発明の実施の形態を説明したが、これらの実施形態は一例であり、要旨を逸脱しない範囲内で種々変更して実施できる。また、本発明の権利範囲がこれらの実施形態に限定されず、本発明の要旨を逸脱しない範囲において種々なる態様で実施し得ることは言うまでもない。   The embodiments of the present invention have been described above with reference to the embodiments. However, these embodiments are merely examples, and various modifications can be made without departing from the scope of the invention. Further, it goes without saying that the scope of rights of the present invention is not limited to these embodiments and can be implemented in various modes without departing from the gist of the present invention.

すなわち、上記各実施形態では車体前方にラジエータの存在する構造を例としたが、これに限定せずエンジンルーム１３に代えて車体前方にトランクルームが設けられていてもよい。あるいは板状部材としてのガーニッシュやライセンスプレートホルダ以外にも、フロントグリル自体を開閉可能とする構造や、ラジエータ取風口がバンパ下に設けられた構造に応用してもよい。   That is, in each of the above embodiments, the structure in which the radiator is present in the front of the vehicle body is taken as an example, but the present invention is not limited to this, and a trunk room may be provided in front of the vehicle body instead of the engine room 13. Alternatively, besides the garnish or license plate holder as a plate-like member, the present invention may be applied to a structure in which the front grill itself can be opened or closed, or a structure in which a radiator air inlet is provided below the bumper.
