Description

本発明は、キャブの後方に荷箱が搭載される車両のルーフ構造に関する。   The present invention relates to a vehicle roof structure in which a cargo box is mounted behind a cab.

特許文献１には、荷台にバンが設置されたバン型トラックが記載されている。このトラックのキャブのルーフ前端部には、略全幅にわたって樹脂製で板状の基材が取付けられ、さらに、該基材の前端部中央には別体のエアベーンが突設されている。基材は、キャブのルーフに形成した凹部を覆うようにして取付けられ、フロントガラスの上端とルーフ面との間に連続感をもたらすように配慮されている。エアベーンは、樹脂を成形した長さＬの細長い部品であり、その前壁が走行風の気流を斜め上方へ変化させるような断面形状になっている。エアベーンの長さＬは、バンの幅Ｗに対して中央部の１８％〜４０％程度とする。   Patent Document 1 describes a van type truck in which a van is installed on a loading platform. A plate-like base material made of resin is attached to the front end portion of the roof of the cab of this truck, and a separate air vane projects from the center of the front end portion of the base material. The base material is attached so as to cover a recess formed in the roof of the cab, and consideration is given to providing a continuity between the upper end of the windshield and the roof surface. The air vane is a long and thin part having a length L formed by molding a resin, and its front wall has a cross-sectional shape that changes the airflow of the traveling wind obliquely upward. The length L of the air vane is about 18% to 40% of the central portion with respect to the width W of the van.

実開平５−６４０７９号公報Japanese Utility Model Publication No. 5-64079

特許文献１に記載のトラックでは、基材がキャブのルーフ前端部の略全幅にわたって配慮され、エアベーンがバンの幅Ｗに対して中央部の１８％〜４０％程度の長さＬで基材の前端部中央に突設されるので、キャブの車幅方向外側の斜め前方（以下、単に斜め前方という）からの走行風をキャブの前面に受けると、基材とエアベーンとの境目（以下、エアベーンの両端という）に車幅方向の両端部に走行風が当たる。このため、エアベーンの両端の形状によっては、斜め前方からの走行風を上方へ案内することができず、走行風が荷箱の前面に衝突して車両が受ける空気抵抗が増大するおそれがある。例えば、エアベーンの両端が開口している場合には、斜め前方からの走行風が、エアベーンの両端からエアベーンの内部に入り込み、空気抵抗が増大するおそれがある。   In the truck described in Patent Document 1, the base material is considered over substantially the entire width of the front end portion of the roof of the cab, and the air vane has a length L of about 18% to 40% of the central portion with respect to the width W of the van. Since it is projected at the center of the front end, when the driving wind from the diagonally forward side of the cab in the vehicle width direction (hereinafter simply referred to as diagonally forward) is received on the front surface of the cab, the boundary between the base material and the air vane (hereinafter referred to as air vane) Traveling wind hits both ends in the vehicle width direction. For this reason, depending on the shape of both ends of the air vane, it is not possible to guide the traveling wind from diagonally forward, and the traveling wind may collide with the front surface of the cargo box and increase the air resistance received by the vehicle. For example, when both ends of the air vane are open, traveling wind from obliquely forward may enter the air vane from both ends of the air vane, and air resistance may increase.

そこで、本発明は、キャブの斜め前方からの走行風による空気抵抗を低減させることが可能なキャブのルーフ構造の提供を目的とする。   Therefore, an object of the present invention is to provide a roof structure of a cab that can reduce air resistance caused by traveling wind from diagonally forward of the cab.

上記課題を解決するため、本発明は、キャブの後方に荷箱が搭載され、荷箱の前面がキャブのルーフよりも上方に露出する車両のルーフ構造であって、ルーフ前面部とルーフ上面部とルーフ前上角部とを備える。ルーフ前面部は、キャブのフロントガラスの上端縁部から上方へ延びる。ルーフ上面部は、ルーフ前面部よりも後上方に配置されて上下方向と交叉する。ルーフ前上角部は、断面弧状の左右１対の湾曲面部と断面略Ｌ字状の突出面部と左右１対の側面部とを有し、ルーフ前面部の上方且つルーフ上面部の前方で車幅方向に延びてルーフ前面部とルーフ上面部とを連結する。左右１対の湾曲面部は、ルーフ前上角部の車幅方向両端部に上側に湾曲した状態で配置されてルーフ前面部とルーフ上面部との間を閉止する。断面略Ｌ字状の突出面部は、左右の湾曲面部の間の略全域で車幅方向に延びて左右の湾曲面部よりも上側に突出してルーフ前面部とルーフ上面部との間を閉止する。左右１対の側面部は、車幅方向と交叉して突出面部の車幅方向両端縁と左右の湾曲面部の車幅方向内端縁との間を閉止する。   In order to solve the above problems, the present invention provides a vehicle roof structure in which a cargo box is mounted on the rear side of a cab, and the front surface of the cargo box is exposed above the roof of the cab. And an upper front corner of the roof. The front surface of the roof extends upward from the upper edge of the windshield of the cab. The roof upper surface portion is disposed rearward and upper than the roof front surface portion and intersects the vertical direction. The upper front corner portion of the roof has a pair of left and right curved surface portions having an arcuate cross section, a protruding surface portion having a substantially L-shaped cross section, and a pair of left and right side portions, and is positioned above the roof front portion and in front of the roof upper surface portion. It extends in the width direction and connects the roof front surface portion and the roof upper surface portion. The pair of left and right curved surface portions are arranged in a state of being curved upward at both ends in the vehicle width direction of the upper front corner portion of the roof, and closes between the roof front surface portion and the roof upper surface portion. The projecting surface portion having a substantially L-shaped cross section extends in the vehicle width direction in substantially the entire region between the left and right curved surface portions, projects upward from the left and right curved surface portions, and closes between the roof front surface portion and the roof upper surface portion. The pair of left and right side portions intersects the vehicle width direction and closes between the both ends of the protruding surface portion in the vehicle width direction and the inner edges of the left and right curved surface portions in the vehicle width direction.

上記構成では、ルーフ前上角部の左右の側面部が、車幅方向と交叉して突出面部の車幅方向両端縁と左右の湾曲面部の車幅方向内端縁との間を閉止するので、ルーフが斜め前方からの走行風を受けた際に、左右の湾曲面部に沿って上方の車幅方向内側へ流れる走行風が左右の側面部に当たると、左右の側面部によって走行風が上方へ案内される。このように、斜め前方からの走行風を左右の側面部によって上方へ案内することができるので、荷箱の前面への走行風の衝突を抑えて空気抵抗を低減することができる。また、ルーフ前上角部の左右の側面部が、車幅方向と交叉して突出面部の車幅方向両端縁と左右の湾曲面部の車幅方向内端縁との間を閉止するので、突出面部の内部への走行風の入り込みを防止することができ、空気抵抗を低減することができる。   In the above configuration, the left and right side surfaces of the upper front corner of the roof cross the vehicle width direction and close the space between both ends of the protruding surface portion in the vehicle width direction and the inner edges of the left and right curved surface portions in the vehicle width direction. When the driving wind flowing diagonally forward from the front and the driving wind flowing inward in the vehicle width direction along the left and right curved surface portions hits the left and right side portions, the driving wind is moved upward by the left and right side portions. Guided. Thus, since the traveling wind from diagonally forward can be guided upward by the left and right side portions, the collision of the traveling wind with the front surface of the cargo box can be suppressed and the air resistance can be reduced. In addition, the left and right side surfaces of the upper front corner of the roof cross the vehicle width direction and close the space between both ends of the protruding surface portion in the vehicle width direction and the inner edge in the vehicle width direction of the left and right curved surface portions. It is possible to prevent the traveling wind from entering the inside of the surface portion, and to reduce the air resistance.

また、ルーフ前上角部は、その車幅方向両端部に配置される断面弧状の左右の湾曲面部と、左右の湾曲面部の間の略全域で車幅方向に延びて左右の湾曲面部よりも上側に突出する断面略Ｌ字状の突出面部とを有する。このため、車両の走行中のキャブの正面からの走行風は、ルーフの車幅方向外端部では、左右の湾曲面部によって後方へ案内され、ルーフの車幅方向外端部の間の車幅方向中央部の略全域では、突出面部によって上方へ案内される。このように、ルーフ前上角部の車幅方向両端部を除く車幅方向中央部の略全域で、走行風を上方へ案内することができるので、荷箱の前面への走行風の衝突を抑えて空気抵抗を低減することができる。   Further, the upper front corner portion of the roof extends in the vehicle width direction substantially over the entire area between the left and right curved surface portions, and the left and right curved surface portions between the left and right curved surface portions. And a projecting surface portion having a substantially L-shaped cross section projecting upward. For this reason, the traveling wind from the front of the cab during traveling of the vehicle is guided rearward by the left and right curved surface portions at the outer end portion in the vehicle width direction of the roof, and the vehicle width between the outer end portions in the vehicle width direction of the roof In substantially the entire region in the center of the direction, the projection is guided upward by the protruding surface portion. In this way, the traveling wind can be guided upward in substantially the entire vehicle width direction except for both ends in the vehicle width direction of the upper corner in front of the roof. It can suppress and can reduce air resistance.

また、ルーフ前上角部の車幅方向両端部が断面弧状の湾曲面部であり、鋭角の角部ではないので、例えば、ルーフを金属製の板体によって構成し、ルーフ前上角部の車幅方向両端部に対して他の板体（ルーフの車幅方向両側で起立する側板等）を前後方向に重ねた状態で接合する際には、その接合面を合わせ易く、接合作業を容易に行うことができる。   In addition, since both ends in the vehicle width direction of the upper corner in front of the roof are curved surface portions having a cross-sectional arc shape and not acute corners, for example, the roof is formed of a metal plate, and the vehicle in the upper corner in front of the roof When joining other plate bodies (side plates that stand on both sides in the vehicle width direction of the roof) in the front-rear direction to the both ends in the width direction, it is easy to match the joining surfaces and facilitate the joining work. It can be carried out.

また、上記ルーフ前面部は、フロントガラスの上端縁部からフロントガラスの延設方向に沿って上方へ延びてもよく、上記ルーフ前上角部の突出面部は、ルーフ前面部を延設方向に沿って上方へ延長した上側前面部と、上側前面部の上端縁から後方のルーフ上面部へ連続する前側上面部とを有してもよい。   The roof front portion may extend upward from the upper edge of the windshield along the windshield extending direction, and the projecting surface portion of the upper front corner of the roof may extend the roof front portion in the extending direction. You may have an upper side front part extended upward along, and a front side upper part which continues from the upper end edge of an upper side front part to the back roof upper surface part.

上記構成では、ルーフ前面部と、ルーフ前上角部の突出面部の上側前面部とが、フロントガラスの延設方向に沿って延びるので、キャブの前面の凹凸を抑えることができ、キャブの前面の空気抵抗を低減することができる。   In the above configuration, since the roof front surface and the upper front surface of the projecting surface portion of the upper front corner of the roof extend along the extending direction of the windshield, unevenness on the front surface of the cab can be suppressed, and the front surface of the cab The air resistance can be reduced.

本発明によれば、キャブの斜め前方からの走行風による空気抵抗を低減させることができる。   According to the present invention, it is possible to reduce the air resistance due to the traveling wind from diagonally forward of the cab.

Both ends in the vehicle width direction of the projecting surface portion 20 are disposed on the outer side in the vehicle width direction with respect to the large beads 18a at both ends in the vehicle width direction of the top panel 12a. The projecting surface portion 20 includes an upper front portion 22 extending upward along the extending direction of the windshield 5 and the roof front portion 15 from the upper end 15b of the center portion in the vehicle width direction of the roof front portion 15, and the upper end of the upper front portion 22. It has a front upper surface portion 23 that curves backward from the edge and continues to the front end 16a of the center portion in the vehicle width direction of the roof upper surface portion 16, and is formed in a substantially L-shaped cross section. The curved portion where the upper front surface portion 22 and the front upper surface portion 23 intersect is curved upward, and the curvature radius thereof is smaller than the curvature radius of the left and right curved surface portions 19. The rear end edge portion of the front upper surface portion 23 is inclined rearward and downward and continues to the front end 16 a of the roof upper surface portion 16. The upper surface of the front upper surface portion 23 of the protruding surface portion 20 is disposed at substantially the same height as the upper surfaces of the plurality of beads 18. That is, a recess 26 extending in the vehicle width direction is formed between the upper surface of the front upper surface portion 23 of the protruding surface portion 20 and the upper surfaces of the plurality of beads 18. In the present invention, the term “curve upward” refers to a virtual plane connecting the upper end 15b of the roof front surface portion 15 and the front end 16a of the roof upper surface portion 16 (a line indicated by a one-dot chain line 9 in FIG. 4 is extended in the vehicle width direction). It is used in the sense that it curves so as to protrude upward from the surface.

左右の側面部２１は、第１パネル１１の一部であって、車幅方向と交叉して、左右の湾曲面部１９の車幅方向内端縁と、突出面部２０の上側前面部２２の車幅方向外端縁と、突出面部２０の前側上面部２３の車幅方向外端縁との間を閉止する。左右の側面部２１は、左右の湾曲面部１９の車幅方向内端縁から上方の車幅方向内側へ僅かに傾斜した状態で起立する。   The left and right side surfaces 21 are part of the first panel 11, intersecting the vehicle width direction, the vehicle width direction inner edges of the left and right curved surface portions 19, and the vehicle on the upper front surface portion 22 of the protruding surface portion 20. The space between the outer edge in the width direction and the outer edge in the vehicle width direction of the front upper surface portion 23 of the protruding surface portion 20 is closed. The left and right side surfaces 21 stand in a state where the left and right curved surface portions 19 are slightly inclined from the inner edge in the vehicle width direction to the inner side in the upper vehicle width direction.

上記のように構成されたトラック１のルーフパネル１０では、ルーフ前上角部１７の左右の側面部２１が、車幅方向と交叉して、左右の湾曲面部１９の車幅方向内端縁と、突出面部２０の上側前面部２２の車幅方向外端縁と、突出面部２０の前側上面部２３の車幅方向外端縁との間を閉止するので、ルーフパネル１０が斜め前方からの走行風を受けた際に、左右の湾曲面部１９に沿って上方の車幅方向内側へ流れる走行風が左右の側面部２１に当たると、左右の側面部２１によって走行風が上方へ案内される。このように、斜め前方からの走行風を左右の側面部２１によって上方へ案内することができるので、荷箱４の前面４ａへの走行風の衝突を抑えて空気抵抗を低減することができる。また、左右の側面部２１が、車幅方向と交叉して左右の湾曲面部１９の車幅方向内端縁と、突出面部２０の上側前面部２２の車幅方向外端縁と、突出面部２０の前側上面部２３の車幅方向外端縁との間を閉止するので、突出面部２０の内部への走行風の入り込みを防止することができ、空気抵抗を低減することができる。   In the roof panel 10 of the truck 1 configured as described above, the left and right side surfaces 21 of the upper front corner portion 17 of the roof intersect with the vehicle width direction and the inner edge in the vehicle width direction of the left and right curved surface portions 19. In addition, since the space between the outer edge in the vehicle width direction of the upper front surface portion 22 of the projecting surface portion 20 and the outer edge in the vehicle width direction of the front upper surface portion 23 of the projecting surface portion 20 is closed, the roof panel 10 travels obliquely from the front. When traveling wind that flows inward in the vehicle width direction along the left and right curved surface portions 19 hits the left and right side portions 21 when the wind is received, the traveling wind is guided upward by the left and right side portions 21. Thus, since the traveling wind from diagonally forward can be guided upward by the left and right side portions 21, the collision of the traveling wind with the front surface 4a of the cargo box 4 can be suppressed and the air resistance can be reduced. In addition, the left and right side portions 21 intersect with the vehicle width direction, the vehicle width direction inner end edges of the left and right curved surface portions 19, the vehicle width direction outer end edges of the upper front portion 22 of the protrusion surface portion 20, and the protrusion surface portions 20. Since the space between the front upper surface portion 23 and the outer edge in the vehicle width direction is closed, it is possible to prevent the traveling wind from entering the projecting surface portion 20 and to reduce the air resistance.

従って、本実施形態によれば、キャブ２の斜め前方からの走行風による空気抵抗を低減させることができる。   Therefore, according to the present embodiment, the air resistance due to the traveling wind from diagonally forward of the cab 2 can be reduced.

また、ルーフパネル１０の前上方のルーフ前上角部１７が、車幅方向両端部の左右の湾曲面部１９と、左右の湾曲面部１９の間の略全域で車幅方向に延びて左右の湾曲面部１９よりも上側に突出する突出面部２０とを有する。このため、トラック１の走行中のキャブ２の正面からの走行風は、ルーフパネル１０のルーフ前上角部１７の車幅方向外端部では、左右の湾曲面部１９によって後方へ案内され、ルーフ前上角部１７の車幅方向外端部の間の車幅方向中央部の略全域では、突出面部２０によって上方へ案内される。このように、ルーフ前上角部１７の車幅方向両端部を除く車幅方向中央部の略全域で、走行風を上方へ案内することができるので、荷箱４の前面４ａへの走行風の衝突を抑えて空気抵抗を低減することができる。   In addition, the upper front corner 17 of the roof upper front portion of the roof panel 10 extends in the vehicle width direction in substantially the entire region between the left and right curved surface portions 19 at both ends in the vehicle width direction and the left and right curved surface portions 19. And a projecting surface portion 20 projecting upward from the surface portion 19. For this reason, the traveling wind from the front of the cab 2 while the truck 1 is traveling is guided rearward by the left and right curved surface portions 19 at the vehicle width direction outer end portion of the roof front upper corner portion 17 of the roof panel 10. In the substantially entire region of the vehicle width direction central portion between the vehicle width direction outer end portions of the front upper corner portion 17, it is guided upward by the protruding surface portion 20. In this way, since the traveling wind can be guided upward in substantially the entire vehicle width direction central portion excluding both ends in the vehicle width direction of the upper front corner portion 17 of the roof, the traveling wind toward the front surface 4a of the packing box 4 can be guided. The air resistance can be reduced by suppressing the collision.

また、ルーフ前面部１５とルーフ前上角部１７の突出面部２０の上側前面部２２とが、フロントガラス５の延設方向に沿って延びるので、キャブ２の前面の凹凸を抑えることができ、キャブ２の前面の空気抵抗を低減することができる。   Moreover, since the front surface portion 15 of the roof and the upper front surface portion 22 of the projecting surface portion 20 of the upper front corner portion 17 of the roof extend along the extending direction of the windshield 5, the unevenness on the front surface of the cab 2 can be suppressed. The air resistance on the front surface of the cab 2 can be reduced.

また、ルーフ前上角部１７の車幅方向両端部が断面弧状の湾曲面部１９であり、鋭角の角部ではないので、第１パネル１１の車幅方向両端部と、第３パネル１３及び第４パネル１４の前湾曲部１３ｂ，１４ｂとを接合する際に、前後方向に重ね易く、接合作業を容易に行うことができる。   In addition, since both ends in the vehicle width direction of the upper front corner portion 17 of the roof are curved surface portions 19 having an arc cross section and not acute corner portions, both end portions in the vehicle width direction of the first panel 11, the third panel 13, When joining the front curved portions 13b and 14b of the four panel 14, it is easy to overlap in the front-rear direction, and the joining work can be easily performed.

また、本実施形態では、突出面部２０の上側前面部２２を、フロントガラス５及びルーフ前面部１５の延設方向に沿って延ばしたが、上側前面部２２を延ばす方向は、これに限定されるものではない。   Moreover, in this embodiment, although the upper front part 22 of the protrusion surface part 20 was extended along the extending direction of the windshield 5 and the roof front part 15, the direction which extends the upper front part 22 is limited to this. It is not a thing.

また、本実施形態では、ルーフパネル１０の第１パネル１１とフロントガラス５の上端縁部とを固定したが、これに限定されるものではない。例えば、図６に示すように、フロントガラス５の上方にフロントガラス５の上端縁部を支持する枠部３０が設けられる場合には、枠部３０に対してルーフパネル１０の第１パネル１１を固定してもよい。この場合、キャブ２の前面のうちフロントガラス５よりも上方且つ所定の高さ位置よりも下方の領域を構成する部分であるルーフ前面部には、第１パネル１１の前面を構成する部分の他に枠部３０の前面部３０ａも含まれる。   Moreover, in this embodiment, although the 1st panel 11 of the roof panel 10 and the upper end edge part of the windshield 5 were fixed, it is not limited to this. For example, as shown in FIG. 6, when the frame portion 30 that supports the upper edge of the windshield 5 is provided above the windshield 5, the first panel 11 of the roof panel 10 is attached to the frame portion 30. It may be fixed.
