Description

車両の前部構造Vehicle front structure
　本発明は車両の前部構造に関する。 The present invention relates to a front structure of a vehicle.
　日本国実開平０２－９３１２４号公報は、ダッシュパネルの前方の車両前部空間にエンジン及びエアクリーナが配置され、フロントピラーから車両前方に延在するアッパーフレームと、アッパーフレームの車幅方向外側に設けられたフェンダーパネルとの間に、エアクリーナの空気取り入れ口が配置された車両、を開示する。
　この車両では、走行時に、フロントグリルの開口から車両前部空間に導入された空気が、フェンダーパネルの車幅方向内側とアッパーフレームとの間を通り、エアクリーナの空気取り入れ口に至る。 In Japanese Utility Model Laid-Open No. 02-93124, an engine and an air cleaner are arranged in a vehicle front space in front of a dash panel, and an upper frame extending from a front pillar to a vehicle front side is provided outside a vehicle width direction of the upper frame. A vehicle in which an air intake port of an air cleaner is disposed between the fender panel and the fender panel.
In this vehicle, the air introduced into the vehicle front space from the opening of the front grill during traveling travels between the vehicle width direction inner side of the fender panel and the upper frame and reaches the air intake port of the air cleaner.
　ところで、このような車両において、アッパーフレームの上端の上方に、フェンダーパネルの上端フランジが配置される場合、フェンダーパネルの上端フランジとアッパーフレームの上端との間には、フェンダーパネルおよびアッパーフレームの製造上の誤差を吸収するために、ある程度の隙間が形成される。
　そのため、車両前部空間内でエンジンにより暖められた温度の高い空気が、フェンダーパネルの上端フランジとアッパーフレームの上端との間の隙間から、フェンダーパネルとアッパーフレームとの間の空間に流れ込み、温度の高い空気が空気取り入れ口からエアクリーナに吸い込まれるおそれがある。
　このように温度の高い空気がエアクリーナに供給されると、燃焼効率の低下を招き燃費が低下することが懸念される。 By the way, in such a vehicle, when the upper end flange of the fender panel is arranged above the upper end of the upper frame, the fender panel and the upper frame are manufactured between the upper end flange of the fender panel and the upper end of the upper frame. A gap is formed to some extent to absorb the above error.
Therefore, high-temperature air warmed by the engine in the vehicle front space flows into the space between the fender panel and the upper frame from the gap between the upper flange of the fender panel and the upper end of the upper frame, High air may be drawn into the air cleaner through the air intake.
When the air having such a high temperature is supplied to the air cleaner, there is a concern that the combustion efficiency is lowered and the fuel efficiency is lowered.
　本発明の実施の形態は、エンジンの燃焼効率が確保されて燃費が向上し、フードの変形ストロークが確保されて歩行者保護性能が向上した車両の前部構造、に関する。 Embodiments of the present invention relate to a front structure of a vehicle in which combustion efficiency of an engine is secured, fuel consumption is improved, and a hood deformation stroke is secured to improve pedestrian protection performance.
　本発明の実施の形態によれば、車両前部に位置するエンジンルームの車幅方向外側で車両前後方向に延在するアッパーフレームと、前記アッパーフレームの車幅方向外側に設けられるフェンダーパネルとの間にエアクリーナの空気取り入れ口が配置される。前記フェンダーパネルの上部で車幅方向内側に延びたフランジ部が、ブラケットを介して前記アッパーフレームの上面に対して上方に隙間を有して固定される。フェンダーガーニッシュが、前記アッパーフレームと前記フランジ部との前記隙間を車幅方向内側から覆うように車両の前後方向に延在する。フェンダーガーニッシュが、前記エンジンルームを開閉するフードを下方から支持する。前記フェンダーガーニッシュは、前記アッパーフレームに取り付けられる取付部と、前記アッパーフレームの車幅方向内側から前記隙間を覆う遮蔽部と、前記フェンダーパネルの前記フランジ部の上方に所定の間隔を設けて配設されて前記フードを支持する支持部と、を含む。 According to the embodiment of the present invention, an upper frame extending in the vehicle front-rear direction on the vehicle width direction outer side of the engine room located in the vehicle front portion, and a fender panel provided on the vehicle width direction outer side of the upper frame. The air intake of the air cleaner is arranged between them. A flange portion extending inward in the vehicle width direction at an upper portion of the fender panel is fixed to the upper surface of the upper frame via a bracket with an upward gap. A fender garnish extends in the front-rear direction of the vehicle so as to cover the gap between the upper frame and the flange portion from the inside in the vehicle width direction. A fender garnish supports a hood that opens and closes the engine room from below. The fender garnish is provided with a mounting portion mounted on the upper frame, a shielding portion covering the gap from the vehicle width direction inner side of the upper frame, and a predetermined gap provided above the flange portion of the fender panel. And a support portion that supports the hood.
　本発明の実施の形態によれば、温度の高い空気が空気取り入れ口からエアクリーナに吸い込まれることが、フェンダーガーニッシュにより防止される。この結果、エンジンの燃焼効率が確保され、燃費が向上する。
　また、本発明の実施の形態によれば、フードの上方から斜め後方に向かって例えば歩行者の頭部が衝突した際、フードはフェンダーガーニッシュを変形させながら下方に変形する。このため、フードがフェンダーパネルに当接する前に衝突エネルギーが吸収される。この結果、衝撃吸収性能が向上し、歩行者保護性能が向上する。 According to the embodiment of the present invention, the fender garnish prevents high temperature air from being sucked into the air cleaner from the air intake port. As a result, the combustion efficiency of the engine is secured and the fuel economy is improved.
Further, according to the embodiment of the present invention, when the head of a pedestrian collides from the upper side of the hood diagonally rearward, the hood deforms downward while deforming the fender garnish. Therefore, the collision energy is absorbed before the hood contacts the fender panel. As a result, the impact absorption performance is improved and the pedestrian protection performance is improved.

The lower plate portion 46 projects inward in the vehicle width direction from the upper portion of the mounting portion 44.
The vertical plate portion 47 extends upward from the end of the horizontal plate portion 46 on the inner side in the vehicle width direction.
The upper plate portion 48 extends outward from the upper end of the vertical plate portion 47 in the vehicle width direction. Further, the upper plate portion 48 is inclined in the front portion 42A of the fender garnish 42 so as to be gradually displaced upward toward the outer side in the vehicle width direction.
In other words, the vertical plate portion 47 faces the gap S2 and extends in the vertical direction. The lower plate portion 46 extends outward from the lower end of the vertical plate portion 47 in the vehicle width direction and is connected to the mounting portion 44. The upper plate portion 48 extends outward from the upper end of the vertical plate portion 47 in the vehicle width direction and is connected to a support portion 50 described later.

　言い換えると、支持部５０は、フェンダーパネル１６のフランジ部１６０２の上方に所定の間隔を設けて配設されてフード１８を支持する。
　なお、図５に示すように、フェンダーガーニッシュ４２の車両後方の箇所である後部４２Ｂでは、下板部４６の突出量が前部４２Ａに比べ小さく、縦板部４７が前部４２Ａに比べ車幅方向外側に位置している。また、上板部４８は傾斜していない。
　フェンダーガーニッシュ４２の前部４２Ａと後部４２Ｂとの境界では、縦板部４７が後方に至るにつれて車幅方向外側に傾斜した縦板傾斜部４７０２となっており、前部４２Ａと後部４２Ｂとを連結している。 The support portion 50 is provided on the upper end of the shielding portion 45, extends above the flange portion 1602 of the fender panel 16 and extends outward in the vehicle width direction, contacts the hood 18 on the upper surface, and connects the hood 18 and the fender garnish 42. A weather strip 54 that seals the gap is supported. That is, the support portion 50 supports the hood 18 from below via the weather strip 54.
In other words, the support portion 50 is disposed above the flange portion 1602 of the fender panel 16 with a predetermined space therebetween to support the hood 18.
As shown in FIG. 5, in the rear portion 42B, which is the vehicle rear portion of the fender garnish 42, the amount of protrusion of the lower plate portion 46 is smaller than that in the front portion 42A, and the vertical plate portion 47 is in the vehicle width compared to the front portion 42A. It is located outside the direction. Further, the upper plate portion 48 is not inclined.
At the boundary between the front portion 42A and the rear portion 42B of the fender garnish 42, the vertical plate portion 47 is a vertical plate inclined portion 4702 that is inclined outward in the vehicle width direction toward the rear, connecting the front portion 42A and the rear portion 42B. is doing.
　図３、図５、図６、図８に示すように、ウェザーストリップ支持板部５０の下面には、フランジ部１６０２に当接する脚部５００２が垂設されている。
　脚部５００２は、下方に至るにつれて車両後方に変位するよう傾斜して形成されている。 As shown in FIG. 3, FIG. 5, FIG. 6, and FIG. 8, leg portions 5002 that abut the flange portion 1602 are vertically provided on the lower surface of the weather strip support plate portion 50.
The leg portion 5002 is formed so as to be inclined so as to be displaced rearward of the vehicle as it goes downward.
　図３、図６、図７に示すように、フェンダーガーニッシュ４２の前端は、フェンダーガーニッシュ４２の遮蔽部４５とアッパーフレーム３４とで囲まれる空間Ｓ１が車両前方に開放されるように開口部５６が形成されている。これにより、車両前方からフェンダーガーニッシュ４２に向かい流れる空気を、空間Ｓ１内に取り込むことが可能となっている。
　すなわち、図５、図６、図７に示すように、フェンダーガーニッシュ４２の車両前方側端部４２０２は、フェンダーガーニッシュ４２とアッパーフレーム３４とで囲まれる空間Ｓ１に車両前方側から空気を取り込み可能となるように車両前方に開放されている。
　また、フェンダーガーニッシュ４２とアッパーフレーム３４との間の空間Ｓ１は、車両前方側（前部４２Ａ）の大きさが車両後方側（後部４２Ｂ）の大きさに比べ大きくなるように形成されている。本実施形態では、後部４２Ｂの縦板部４７が前部４２Ａの縦板部４７よりも車幅方向外側に位置している、すなわち、アッパーフレーム３４に接近していることによって、空間Ｓ１を小さくしている。 As shown in FIGS. 3, 6, and 7, the front end of the fender garnish 42 has an opening 56 so that the space S1 surrounded by the shielding portion 45 of the fender garnish 42 and the upper frame 34 is opened to the front of the vehicle. Has been formed. As a result, the air flowing from the front of the vehicle toward the fender garnish 42 can be taken into the space S1.
That is, as shown in FIGS. 5, 6, and 7, the vehicle front side end portion 4202 of the fender garnish 42 can take in air from the vehicle front side into the space S1 surrounded by the fender garnish 42 and the upper frame 34. It is open to the front of the vehicle.
The space S1 between the fender garnish 42 and the upper frame 34 is formed such that the size of the vehicle front side (front part 42A) is larger than the size of the vehicle rear side (rear part 42B). In the present embodiment, the vertical plate portion 47 of the rear portion 42B is located outside the vertical plate portion 47 of the front portion 42A in the vehicle width direction, that is, close to the upper frame 34, thereby reducing the space S1. is doing.
　したがって、フロントグリル１４の開口１４０２から導入された空気Ａの一部は、車幅方向の右側部のフェンダー空間Ｓ３に導かれ、エアクリーナ２２の空気取り入れ口２２０２に吸入される。
　また、フロントグリル１４の開口１４０２から車両前部空間Ｓに導入された空気Ａの一部は、フェンダーガーニッシュ４２の開口部５６から空間Ｓ１に導かれ、フランジ部１６０２とアッパーフレーム３４の上横板部３８の間の隙間Ｓ２を通り、エアクリーナ２２の空気取り入れ口２２０２に吸入される。 Therefore, a part of the air A introduced from the opening 1402 of the front grill 14 is guided to the fender space S3 on the right side in the vehicle width direction and is sucked into the air intake 2202 of the air cleaner 22.
Further, a part of the air A introduced into the vehicle front space S from the opening 1402 of the front grill 14 is guided to the space S1 from the opening 56 of the fender garnish 42, and the flange portion 1602 and the upper horizontal plate of the upper frame 34. It is sucked into the air intake 2202 of the air cleaner 22 through the gap S2 between the portions 38.
　本実施の形態によれば、図３に示すように、フェンダーガーニッシュ４２が、空気取り入れ口２２０２の上方でアッパーフレーム３４の上端の車幅方向内側およびフランジ部１６０２の車幅方向内側を通って車両の前後方向に延在している。このため、車両前部空間Ｓ内でエンジン２０により暖められた温度の高い空気が、フェンダーパネル１６のフランジ部１６０２とアッパーフレーム３４の上横板部４６との間の隙間Ｓ２から、フェンダーパネル１６とアッパーフレーム３４との間のフェンダー空間Ｓ３に流れ込み、温度の高い空気が空気取り入れ口２２０２からエアクリーナ２２に吸い込まれることが、フェンダーガーニッシュ４２により防止される。
　したがって、エンジン２０の燃焼効率が確保され、燃費が向上する。
　また、フェンダーガーニッシュ４２の支持部５０が、フェンダーパネル１６のフランジ部１６０２よりも上方でフード１８を支持する。このため、フード１８の上方から斜め後方に向かって例えば歩行者の頭部が衝突した際、フード１８はフェンダーガーニッシュ４２を変形させながら下方に変形する。この結果、フード１８がフェンダーパネル１６に当接する前に衝突エネルギーを吸収することができ、衝撃吸収性能が向上して歩行者保護性能が向上する。 According to the present embodiment, as shown in FIG. 3, the fender garnish 42 passes through the vehicle width direction inner side of the upper end of the upper frame 34 and the vehicle width direction inner side of the flange portion 1602 above the air intake 2202. It extends in the front-back direction. Therefore, the high-temperature air warmed by the engine 20 in the vehicle front space S passes through the gap S2 between the flange portion 1602 of the fender panel 16 and the upper lateral plate portion 46 of the upper frame 34 to the fender panel 16. The fender garnish 42 prevents the high-temperature air from flowing into the fender space S3 between the upper frame 34 and the upper frame 34 and being sucked into the air cleaner 22 from the air intake 2202.
Therefore, the combustion efficiency of the engine 20 is ensured and the fuel consumption is improved.
Further, the support portion 50 of the fender garnish 42 supports the hood 18 above the flange portion 1602 of the fender panel 16. Therefore, for example, when the head of a pedestrian collides from the upper side of the hood 18 obliquely rearward, the hood 18 deforms downward while deforming the fender garnish 42. As a result, the collision energy can be absorbed before the hood 18 comes into contact with the fender panel 16, the impact absorption performance is improved, and the pedestrian protection performance is improved.
　また、フェンダーガーニッシュ４２の遮蔽部４５が、下板部４６と縦板部４７と上板部４８を有するＵ字状に形成されている。このため、フード１８の上方から斜め後方に向かって歩行者の頭部が衝突した際、フード１８と共にフェンダーガーニッシュ４２が下方に変形しやすい。したがって、フード１８の変形ストロークが確保され、衝撃吸収性能が向上する。
　このとき、上板部４８を車幅方向外側に向かって次第に上方へ変位するよう傾斜させることによって、フード１８の変形ストロークが更に確保され、衝撃吸収性能が向上する。 Further, the shielding portion 45 of the fender garnish 42 is formed in a U shape having a lower plate portion 46, a vertical plate portion 47, and an upper plate portion 48. For this reason, when the head of a pedestrian collides diagonally rearward from above the hood 18, the fender garnish 42 is likely to be deformed downward together with the hood 18. Therefore, the deformation stroke of the hood 18 is secured, and the shock absorbing performance is improved.
At this time, the deformation stroke of the hood 18 is further secured by inclining the upper plate portion 48 so as to gradually move upward toward the vehicle width direction outer side, and the shock absorbing performance is improved.
　また、エンジン２０により暖められた温度の高い空気のエアクリーナ２２への吸い込みを防止するフェンダーガーニッシュ４２を利用して、ウェザーストリップ５４が支持される。このため、ウェザーストリップ５４を支持する専用の支持部材を設ける場合に比べ部品点数が削減される。 Also, the weather strip 54 is supported by using the fender garnish 42 that prevents the high temperature air warmed by the engine 20 from being sucked into the air cleaner 22. Therefore, the number of parts is reduced as compared with the case where a dedicated support member for supporting the weather strip 54 is provided.
　また、フェンダーガーニッシュ４２の車両前方に位置する前端には、フェンダーガーニッシュ４２とアッパーフレーム３４とで囲まれる空間Ｓ１が車両前方に開放された開口部５６が形成されている。このため、走行時、フロントグリル１４の開口１４０２から車両前部空間Ｓに導かれた温度の低い空気が、効率よくフェンダーガーニッシュ４２の内側（フェンダー空間Ｓ３）に導かれる。この結果、温度の低い空気Ａが、空気取り入れ口２２０２からエアクリーナ２２に吸い込まれ、エンジン２０の燃焼効率が確保されて燃費が向上する。 At the front end of the fender garnish 42 located in front of the vehicle, an opening 56 is formed in which a space S1 surrounded by the fender garnish 42 and the upper frame 34 is open to the front of the vehicle. Therefore, when the vehicle is traveling, the air of low temperature introduced into the vehicle front space S from the opening 1402 of the front grill 14 is efficiently introduced into the inside of the fender garnish 42 (fender space S3). As a result, the low temperature air A is sucked into the air cleaner 22 from the air intake 2202, the combustion efficiency of the engine 20 is secured, and the fuel consumption is improved.
　また、車幅方向および上下方向を通る仮想平面で切断した、フェンダーガーニッシュ４２の前部４２Ａの断面形状は、フェンダーガーニッシュ４２の後部４２Ｂの断面形状よりも大きく形成されており、空気取り入れ口２２０２が前部４２Ａ側に設けられている。
　言い換えると、フェンダーガーニッシュ４２の車両前方箇所における空間（フェンダーガーニッシュ４２とアッパーフレーム３４とで囲まれる空間Ｓ１）を車幅方向および上下方向を通る仮想平面で切断した断面形状は、フェンダーガーニッシュ４２の車両後方箇所における空間を車幅方向および上下方向を通る仮想平面で切断した断面形状よりも大きく形成されている。空気取り入れ口２２０２は、フェンダーガーニッシュ４２の車両前方箇所の下方に位置している。
　したがって、走行時、フロントグリル１４の開口１４０２から車両前部空間Ｓに導かれた温度の低い空気が、積極的にフェンダー空間Ｓ３に導かれる。この結果、温度の低い空気が、空気取り入れ口２２０２からエアクリーナ２２に吸い込まれ、エンジン２０の燃焼効率が確保されて、燃費が向上する。
　フェンダーガーニッシュ４２の縦板部４７は、車両後方に至るにつれて車幅方向外側に傾斜する縦板傾斜部４７０２を有する。縦板傾斜部４７０２により、空間Ｓ１は車両後方に至るにつれて小さくなる。このため、温度の低い空気を空気取り入れ口２２０２に導く上で有利となる。 Further, the cross-sectional shape of the front portion 42A of the fender garnish 42 cut along a virtual plane passing through the vehicle width direction and the vertical direction is formed larger than the cross-sectional shape of the rear portion 42B of the fender garnish 42, and the air intake port 2202 is It is provided on the front portion 42A side.
In other words, the cross-sectional shape obtained by cutting the space (the space S1 surrounded by the fender garnish 42 and the upper frame 34) at the vehicle front part of the fender garnish 42 by a virtual plane passing through the vehicle width direction and the vertical direction is the vehicle of the fender garnish 42. It is formed to be larger than a cross-sectional shape obtained by cutting the space at the rear portion with an imaginary plane passing through the vehicle width direction and the vertical direction. The air intake 2202 is located below the vehicle front portion of the fender garnish 42.
Therefore, when the vehicle is traveling, the low temperature air introduced into the vehicle front space S from the opening 1402 of the front grill 14 is positively introduced into the fender space S3. As a result, low-temperature air is sucked into the air cleaner 22 from the air intake 2202, the combustion efficiency of the engine 20 is ensured, and the fuel consumption is improved.
The vertical plate portion 47 of the fender garnish 42 has a vertical plate inclined portion 4702 that inclines outward in the vehicle width direction toward the rear of the vehicle. Due to the vertical plate inclined portion 4702, the space S1 becomes smaller toward the rear of the vehicle. Therefore, it is advantageous for guiding the air having a low temperature to the air intake port 2202.
　また、取付部４４には、取付部４４をアッパーフレーム３４に取着するための取り付け具挿通孔４４０２が設けられ、取り付け具挿通孔４４０２は、上方に至るにつれて車両前方に変位する傾斜の長孔４４０２Ａで形成されている。このため、歩行者の頭部がフード１８に衝突した際、フード１８と共にフェンダーガーニッシュ４２が下方および車両後方に変位しやすい。したがって、フード１８の変形ストロークが確保され、衝撃吸収性能が向上する。 Further, the mounting portion 44 is provided with a mounting tool insertion hole 4402 for mounting the mounting part 44 to the upper frame 34, and the mounting tool insertion hole 4402 is a slender long hole that is displaced toward the front of the vehicle as it goes upward. It is formed of 4402A. Therefore, when the head of a pedestrian collides with the hood 18, the fender garnish 42 is likely to be displaced downward and rearward of the vehicle together with the hood 18. Therefore, the deformation stroke of the hood 18 is secured, and the shock absorbing performance is improved.
　また、支持部５０に、フランジ部１６０２に当接する脚部５００２が垂設され、脚部５００２は、下方に至るにつれて車両後方に変位する傾斜で形成されている。このため、歩行者の頭部がフード１８に衝突した際、フード１８と共にフェンダーガーニッシュ４２が下方および車両後方に変形しやすい。したがって、フード１８の変形ストロークが確保され、衝撃吸収性能が向上する。 Further, a leg portion 5002 that abuts the flange portion 1602 is vertically provided on the support portion 50, and the leg portion 5002 is formed with an inclination that is displaced rearward of the vehicle as it goes downward. Therefore, when the head of the pedestrian collides with the hood 18, the fender garnish 42 is likely to be deformed downward and rearward of the vehicle together with the hood 18. Therefore, the deformation stroke of the hood 18 is secured, and the shock absorbing performance is improved.
