Description

本発明は、車体の下部を被うアンダーカバーに関し、特に基板にその剛性を確保するためのリブが設けられた構成のアンダーカバーに関する。   The present invention relates to an under cover that covers a lower portion of a vehicle body, and more particularly to an under cover having a configuration in which a rib is provided on a substrate to ensure its rigidity.

車体の下部を被うアンダーカバーが知られている。アンダーカバーは、車体に搭載された部材を石跳ねなどから保護するとともに、車両走行時の空気の流れを整流する。そのため、アンダーカバーには車両走行時に受ける風圧に耐える剛性が要求される。
特許文献１に開示されたアンダーカバーでは、基板の上面（車体と対向する側の面）に車幅方向に延びたリブが一体成形されている。このアンダーカバーは、基板を薄型化することで軽量化を図りつつ、リブを設けることによって基板の剛性を確保している。 An undercover that covers the bottom of the car body is known. The under cover protects a member mounted on the vehicle body from rock splashes and rectifies the air flow when the vehicle travels. For this reason, the undercover is required to have a rigidity that can withstand the wind pressure that is received when the vehicle travels.
In the undercover disclosed in Patent Document 1, a rib extending in the vehicle width direction is integrally formed on the upper surface of the substrate (the surface facing the vehicle body). The under cover secures the rigidity of the substrate by providing ribs while reducing the weight by reducing the thickness of the substrate.

特開２０１３−１４４４７４号公報JP 2013-144474 A

特許文献１のアンダーカバーでは、基板に所定の剛性を確保できるようにリブの高さが大きく設定されている。しかし、基板が衝撃荷重を受けて変形し、それに伴いリブが上下方向に撓む際には、リブが高く設定されている分、リブの先端側での変形量が大きくなってリブが破断しやすい。   In the under cover of Patent Document 1, the height of the rib is set large so that a predetermined rigidity can be ensured in the substrate. However, when the substrate is deformed by an impact load and the rib is bent in the vertical direction, the rib is set higher, so the amount of deformation at the tip end of the rib increases and the rib breaks. Cheap.

本発明は、この課題を解決しようとするものであって、その目的は、基板にその剛性を確保するためのリブが設けられたアンダーカバーにおいて、基板が衝撃荷重を受けたときの変形に伴うリブの破断を防ぎ、かつ、リブの役割である基板の剛性は確保することである。   An object of the present invention is to solve this problem, and an object of the present invention is to provide an undercover in which a rib is provided on a substrate to ensure its rigidity, accompanied by deformation when the substrate receives an impact load. It is to prevent the rib from being broken and to ensure the rigidity of the substrate which is the role of the rib.

本発明は、上記の目的を達成するためのもので、以下のように構成されている。本発明のアンダーカバーは、車体の下部を被う基板にその剛性を確保するためのリブが設けられた構成である。リブは、基板の上面に設けられた上リブと、基板の下面に設けられた下リブとによって構成されている。上リブと下リブとの個々の高さは、基板が衝撃荷重を受けた際の基板の変形に伴う上リブと下リブとの個々の変形を、上リブと下リブとがそれぞれ破断しない所定範囲に抑える寸法に設定されている。上リブと下リブとの高さの和は、上リブと下リブとによって基板に要求される剛性を確保できる寸法に設定されている。   The present invention is for achieving the above object, and is configured as follows. The under cover of the present invention has a configuration in which a rib for ensuring rigidity is provided on a substrate covering a lower portion of a vehicle body. The rib is composed of an upper rib provided on the upper surface of the substrate and a lower rib provided on the lower surface of the substrate. The individual heights of the upper rib and the lower rib are determined so that the upper rib and the lower rib are not ruptured due to the individual deformation of the upper rib and the lower rib accompanying the deformation of the substrate when the substrate receives an impact load. The dimensions are set to be within the range. The sum of the heights of the upper rib and the lower rib is set to a dimension that can ensure the rigidity required for the substrate by the upper rib and the lower rib.

さらに好ましくは、つぎのような構成とすることである。アンダーカバーにおいて、基板の複数箇所には、この基板を車体に結合する結合部が設けられている。上リブは、基板の上面に沿って車両の前後方向または左右方向へ延び、かつ、複数の結合部同士を結ぶように配置されている。下リブは、基板の下面に沿って車両の前後方向へのみ延びた状態に配置されている。   More preferably, the following configuration is adopted. In the under cover, coupling portions for coupling the substrate to the vehicle body are provided at a plurality of locations on the substrate. The upper rib extends in the front-rear direction or the left-right direction of the vehicle along the upper surface of the substrate, and is arranged so as to connect a plurality of coupling portions. The lower rib is disposed so as to extend only in the front-rear direction of the vehicle along the lower surface of the substrate.

さらに好ましくは、下リブの一部が車両の前後方向に関して傾斜しており、この傾斜が、車両走行時に基板の下面に沿って流れる空気を、所定の狙いを達成可能に機能させうる方向へ導くように設定されていることである。   More preferably, a part of the lower rib is inclined with respect to the front-rear direction of the vehicle, and this inclination guides the air flowing along the lower surface of the board when the vehicle is traveling in a direction in which the predetermined aim can be achieved. It is set as follows.

本発明では、上リブと下リブとの個々の高さが、基板が衝撃荷重を受けて変形しても上リブと下リブとがそれぞれ破断しない寸法に設定されている。そのため、例えば石跳ね等で基板が衝撃荷重を受けて変形し、それに伴って両リブが上下方向に大きく撓んでそれぞれ破断するのを回避できる。また、本発明では、上リブと下リブとの高さの和が、上リブと下リブとによって基板に要求される剛性を確保できる寸法に設定されている。そのため、リブの役割である基板の剛性は確保される。   In the present invention, the individual heights of the upper rib and the lower rib are set such that the upper rib and the lower rib are not broken even when the substrate is deformed by receiving an impact load. Therefore, for example, it is possible to avoid that the substrate is deformed by receiving an impact load due to, for example, stone jumping, and that both ribs are greatly bent in the vertical direction and broken. In the present invention, the sum of the heights of the upper rib and the lower rib is set to a dimension that can ensure the rigidity required for the substrate by the upper rib and the lower rib. Therefore, the rigidity of the substrate, which is the role of the ribs, is ensured.

本発明では、上リブが、基板を車体に結合する結合部同士を結ぶように配置されていることから、車両走行時の空気抵抗によって基板にかかる荷重を、結合部を通じて車体に受け持たせることができる。そのため、効率的に基板の剛性を向上させることができる。また、本発明では、下リブが車両の前後方向へ延びた状態に配置されていることから、車両走行時に下リブによって空気の流れを効率よく車両後方に導くことができる。そのため、車両走行時の空気抵抗を低減できる。   In the present invention, since the upper rib is arranged so as to connect the coupling portions that couple the board to the vehicle body, the vehicle body can receive the load applied to the board due to the air resistance during vehicle travel through the coupling portion. Can do. Therefore, the rigidity of the substrate can be improved efficiently. In the present invention, since the lower rib is arranged in a state extending in the front-rear direction of the vehicle, the air flow can be efficiently guided to the rear of the vehicle by the lower rib when the vehicle is traveling. Therefore, the air resistance during vehicle travel can be reduced.

本発明では、下リブの一部が、車両走行時に基板の下面に沿って流れる空気を、所定の狙いを達成可能に機能させうる方向へ導くように設定されている。例えば、下リブは、基板の下面に沿って流れる空気を、車両にかかる空気抵抗が低減される方向へ導くように設定される。これによって、車両走行時の空気抵抗を低減できる。   In the present invention, a part of the lower rib is set so as to guide the air flowing along the lower surface of the substrate when the vehicle travels in a direction in which the predetermined aim can be achieved. For example, the lower rib is set so as to guide the air flowing along the lower surface of the substrate in a direction in which the air resistance applied to the vehicle is reduced. As a result, air resistance during vehicle travel can be reduced.

以下、本発明を実施するための形態を、図面を用いて説明する。図１,２に示すように、車両１０は、車体１２、前輪１４、後輪１６、エンジンマフラー１８、アンダーカバー２０を含んで構成されている。   Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the vehicle 10 includes a vehicle body 12, a front wheel 14, a rear wheel 16, an engine muffler 18, and an under cover 20.

アンダーカバー２０は、車体１２の下部の前側、中央両側、および後側に計４個配置されている（図１参照）。これら４個のアンダーカバー２０を説明するとき、それらの個々については前側のアンダーカバー２０Ａ、中央両側のアンダーカバー２０Ｂおよび後側のアンダーカバー２０Ｃとして区別し、これらを総称するときにはアンダーカバー２０として説明する。   A total of four undercovers 20 are disposed on the front side, the center both sides, and the rear side of the lower portion of the vehicle body 12 (see FIG. 1). When these four under covers 20 are described, each of them is distinguished as a front under cover 20A, a central under cover 20B, and a rear under cover 20C. To do.

アンダーカバー２０は、車両１０の走行時の空気の流れを整流するとともに、配置された車体１２の各部分を保護している（図１参照）。車両１０の前側のアンダーカバー２０Ａは、両前輪１４の間から車体１２の前端にかけて配置されてエンジンを保護している。   The under cover 20 rectifies the air flow when the vehicle 10 travels, and protects each portion of the vehicle body 12 that is disposed (see FIG. 1). An under cover 20A on the front side of the vehicle 10 is disposed from between the front wheels 14 to the front end of the vehicle body 12 to protect the engine.

アンダーカバー２０は車体１２の下部を被う基板３０を骨格としている（図１乃至３参照）。基板３０の複数個所には、基板３０と車体１２とを結合するための結合部４０が設けられている。結合部４０は基板３０の外周の各頂点近傍および、隣合う頂点の中間に主として配置されている。各結合部４０には挿通孔Ｈを有する取付座４２が設けられ、これらの取付座４２の挿通孔Ｈに挿通された図示しない結合手段（例えばボルト、クリップ）によって、基板３０と車体１２とが結合されている。   The under cover 20 has a base plate 30 that covers the lower portion of the vehicle body 12 (see FIGS. 1 to 3). At a plurality of locations of the substrate 30, coupling portions 40 for coupling the substrate 30 and the vehicle body 12 are provided. The coupling portion 40 is mainly disposed in the vicinity of each vertex on the outer periphery of the substrate 30 and in the middle between adjacent vertices. Each coupling portion 40 is provided with a mounting seat 42 having insertion holes H, and the substrate 30 and the vehicle body 12 are connected to each other by coupling means (not shown) (for example, bolts and clips) inserted into the insertion holes H of the mounting seats 42. Are combined.

基板３０には、その剛性を確保するためのリブ５０が設けられている（図１乃至４参照）。リブ５０は、基板３０の上面（車体１２と対向する側の面）および下面（路面と対向する側の面）からそれぞれ突出する上リブ５２と下リブ５４とによって構成されている。なお上リブ５２および下リブ５４は、図３,４で示す車両１０の中央右側のアンダーカバー２０Ｂと同様にして、前側のアンダーカバー２０Ａ、中央左側のアンダーカバー２０Ｂおよび後側のアンダーカバー２０Ｃにおいても、これらの基板３０の上面および下面から突出形成されている。   The substrate 30 is provided with ribs 50 for ensuring its rigidity (see FIGS. 1 to 4). The rib 50 includes an upper rib 52 and a lower rib 54 that respectively protrude from the upper surface (the surface facing the vehicle body 12) and the lower surface (the surface facing the road surface) of the substrate 30. The upper rib 52 and the lower rib 54 are formed in the front under cover 20A, the center left under cover 20B, and the rear under cover 20C in the same manner as the center right under cover 20B of the vehicle 10 shown in FIGS. Also, these substrates 30 are formed so as to protrude from the upper and lower surfaces.

上リブ５２と下リブ５４との個々の高さは、基板３０が衝撃荷重を受けた際の基板３０の変形に伴う上リブ５２と下リブ５４との個々の変形を、上リブ５２と下リブ５４とがそれぞれ破断しない所定範囲に抑える寸法に設定されている。上リブ５２と下リブ５４との高さの和は、上リブ５２と下リブ５４とによって基板３０に要求される剛性を確保できる寸法に設定されている。   The individual heights of the upper rib 52 and the lower rib 54 correspond to the individual deformations of the upper rib 52 and the lower rib 54 accompanying the deformation of the substrate 30 when the substrate 30 receives an impact load. The dimensions are set so that the ribs 54 are kept within a predetermined range so as not to break. The sum of the heights of the upper rib 52 and the lower rib 54 is set to a dimension that can ensure the rigidity required for the substrate 30 by the upper rib 52 and the lower rib 54.

上リブ５２は、基板３０の上面に沿って車両１０の前後方向または左右方向へ延び、かつ、隣り合う結合部４０同士を結ぶように配置されている（図２,３参照）。なお、上リブ５２の一部は、車両１０の前後方向または左右方向に関して傾斜した状態で前後方向または左右方向へ延びている。各結合部４０の位置に対応して、上リブ５２は、基板３０の外周にほぼ沿って外周全体にわたって設けられ、また、基板３０の中央を適宜またいでいる。   The upper rib 52 extends in the front-rear direction or the left-right direction of the vehicle 10 along the upper surface of the substrate 30 and is disposed so as to connect adjacent coupling portions 40 (see FIGS. 2 and 3). A part of the upper rib 52 extends in the front-rear direction or the left-right direction while being inclined with respect to the front-rear direction or the left-right direction of the vehicle 10. Corresponding to the position of each coupling portion 40, the upper rib 52 is provided over the entire outer periphery substantially along the outer periphery of the substrate 30, and appropriately straddles the center of the substrate 30.

下リブ５４は、基板３０の下面に沿って車両１０の前後方向へのみ延びた状態に配置される前後リブ５４Ａと、前後方向に関して傾斜した傾斜リブ５４Ｂとによって構成されている（図１参照）。前後リブ５４Ａは、車両１０の左右方向に所定間隔をおいて基板３０に複数設けられている。傾斜リブ５４Ｂは、車両１０の中央両側のアンダーカバー２０Ｂにおいてこれらの基板３０の後輪１６近傍に設けられている。傾斜リブ５４Ｂの傾斜は、車両走行時に基板３０の下面に沿って流れる空気を、車両１０にかかる空気抵抗が低減される方向へ導くように設定されている。詳述すると、傾斜リブ５４Ｂは、車両１０の後方ほど車幅方向の内方へ向かうように延び、基板３０の下面に沿って流れる空気が後輪１６を避けた箇所に導かれるように設定されている。   The lower rib 54 includes a front / rear rib 54A arranged in a state extending only in the front / rear direction of the vehicle 10 along the lower surface of the substrate 30 and an inclined rib 54B inclined with respect to the front / rear direction (see FIG. 1). . A plurality of front and rear ribs 54 </ b> A are provided on the substrate 30 at predetermined intervals in the left-right direction of the vehicle 10. The inclined ribs 54 </ b> B are provided in the vicinity of the rear wheels 16 of these substrates 30 in the under covers 20 </ b> B on both sides of the center of the vehicle 10. The inclination of the inclined rib 54B is set so as to guide the air flowing along the lower surface of the substrate 30 during traveling of the vehicle in a direction in which the air resistance applied to the vehicle 10 is reduced. More specifically, the inclined rib 54B extends toward the inside in the vehicle width direction toward the rear of the vehicle 10, and is set so that the air flowing along the lower surface of the substrate 30 is guided to a location that avoids the rear wheel 16. ing.

本発明は以上のように構成される。アンダーカバー２０では、上リブ５２と下リブ５４との個々の高さが、基板３０が衝撃荷重を受けて変形しても上リブ５２と下リブ５４とがそれぞれ破断しない寸法に設定されている。そのため、例えば石跳ね等で基板３０が衝撃荷重を受けて変形し、それに伴って両リブ５２,５４が上下方向に大きく撓んでそれぞれ破断するのを回避できる。また、アンダーカバー２０では、上リブ５２と下リブ５４との高さの和が、上リブ５２と下リブ５４とによって基板３０に要求される剛性を確保できる寸法に設定されている。そのため、リブ５０の役割である基板３０の剛性は確保される。   The present invention is configured as described above. In the under cover 20, the individual heights of the upper rib 52 and the lower rib 54 are set such that the upper rib 52 and the lower rib 54 do not break even when the substrate 30 is deformed by receiving an impact load. . Therefore, for example, it is possible to avoid that the substrate 30 is deformed by receiving an impact load due to, for example, stone jumping, and the ribs 52 and 54 are greatly bent in the vertical direction and broken accordingly. In the undercover 20, the sum of the heights of the upper rib 52 and the lower rib 54 is set to a dimension that can ensure the rigidity required for the substrate 30 by the upper rib 52 and the lower rib 54. Therefore, the rigidity of the substrate 30 that is the role of the rib 50 is ensured.

アンダーカバー２０では、上リブ５２が、基板３０を車体１２に結合する結合部４０同士を結ぶように配置されていることから、車両１０の走行時の空気抵抗によって基板３０にかかる荷重を、結合部４０を通じて車体１２に受け持たせることができる。そのため、効率的に基板３０の剛性を向上させることができる。   In the under cover 20, the upper rib 52 is disposed so as to connect the coupling portions 40 that couple the substrate 30 to the vehicle body 12, so that the load applied to the substrate 30 due to the air resistance when the vehicle 10 travels is coupled. It can be carried on the vehicle body 12 through the portion 40. Therefore, the rigidity of the substrate 30 can be improved efficiently.

アンダーカバー２０では、前後リブ５４Ａが車両１０の前後方向へ延びた状態に配置されていることから、車両１０の走行時に前後リブ５４Ａによって空気の流れを効率よく車両１０の後方に導くことができる。そのため、車両１０の走行時の空気抵抗を低減できる。   In the under cover 20, the front / rear ribs 54 </ b> A are arranged in a state extending in the front / rear direction of the vehicle 10, so that the air flow can be efficiently guided to the rear of the vehicle 10 by the front / rear ribs 54 </ b> A when the vehicle 10 is traveling. . Therefore, the air resistance when the vehicle 10 is traveling can be reduced.

アンダーカバー２０では、傾斜リブ５４Ｂが、車両１０の走行時に基板３０の下面に沿って流れる空気を、車両１０にかかる空気抵抗が低減される方向へ導くように設定されている。そのため、車両１０の走行時の空気抵抗を低減できる。   In the under cover 20, the inclined rib 54 </ b> B is set so as to guide the air flowing along the lower surface of the substrate 30 when the vehicle 10 is traveling in a direction in which the air resistance applied to the vehicle 10 is reduced. Therefore, the air resistance when the vehicle 10 is traveling can be reduced.

以上は本発明を実施するための最良の形態を図面に関連して説明したが、この実施の形態は本発明の趣旨から逸脱しない範囲で容易に変更または変形できるものである。上述の実施形態において、傾斜リブ５４Ｂは、車両１０の走行時に基板３０の下面に沿って流れる空気が車両１０の後輪１６を避けた箇所に導かれるように設定されていた。しかしながら、傾斜リブ５４Ｂの傾斜方向はこれに限定されるものではなく、車両１０の走行時に基板３０の下面に沿って流れる空気が、例えば車両１０後部のサステンションメンバーのような後輪１６以外の特定の部材を避けた箇所に導かれるように設定されていてもよい。これによって、車両１０の走行時の空気抵抗を低減できる。   Although the best mode for carrying out the present invention has been described above with reference to the drawings, this embodiment can be easily changed or modified without departing from the spirit of the present invention. In the above-described embodiment, the inclined rib 54 </ b> B is set so that the air flowing along the lower surface of the substrate 30 when the vehicle 10 travels is guided to a location that avoids the rear wheel 16 of the vehicle 10. However, the inclination direction of the inclined rib 54B is not limited to this, and the air flowing along the lower surface of the base plate 30 when the vehicle 10 travels is other than the rear wheel 16 such as the suspension member at the rear of the vehicle 10. It may be set to be guided to a place where a specific member is avoided. As a result, the air resistance during travel of the vehicle 10 can be reduced.

また、傾斜リブ５４Ｂは、車両１０の走行時に基板３０の下面に沿って流れる空気が、車両１０を構成する特定の部材が設けられた箇所にあえて導かれるように設定してもよい。これにより、基板３０の下面に沿って流れる空気によって当該特定の部材を冷却できる。   In addition, the inclined rib 54 </ b> B may be set so that air flowing along the lower surface of the substrate 30 when the vehicle 10 is traveling is guided to a place where a specific member constituting the vehicle 10 is provided. Thereby, the specific member can be cooled by the air flowing along the lower surface of the substrate 30.
