Description

本発明は、自動車のスポイラーに関するものである。   The present invention relates to an automobile spoiler.

自動車を高速で走行させた際に発生する揚力を低減させる目的で、車体に装着されたバンパーにスポイラーを取り付けることは従来より周知である（特許文献１参照）。図８はバンパーに取り付ける前の従来のスポイラーを示す斜視図である。ここに示したスポイラー３Ａは硬質樹脂又は金属などの硬質材料により構成され、その上部に多数の取付孔１４Ａが形成されている。かかるスポイラー３Ａを、自動車の車体１Ａに装着されたバンパー２Ａに取り付けるには、スポイラー３Ａをバンパー２Ａの下方にもたらし、そのスポイラー３Ａに形成された各取付孔１４Ａを、図９に示すように、バンパー２Ａに形成された各取付孔９Ａに合致させ、互いに合致した各取付孔９Ａ，１４Ａにクリップ１５Ａを挿入し、そのクリップ１５Ａによってスポイラー３Ａをバンパー２Ａに固定する。   It has been well known that a spoiler is attached to a bumper mounted on a vehicle body for the purpose of reducing lift generated when an automobile is driven at high speed (see Patent Document 1). FIG. 8 is a perspective view showing a conventional spoiler before being attached to a bumper. The spoiler 3A shown here is made of a hard material such as hard resin or metal, and a large number of mounting holes 14A are formed in the upper part thereof. In order to attach the spoiler 3A to the bumper 2A attached to the vehicle body 1A of the automobile, the spoiler 3A is brought under the bumper 2A, and each attachment hole 14A formed in the spoiler 3A is, as shown in FIG. The clip 15A is inserted into the mounting holes 9A and 14A that match each mounting hole 9A formed in the bumper 2A, and the spoiler 3A is fixed to the bumper 2A by the clip 15A.

上述のように、従来のスポイラー３Ａをバンパー２Ａに取り付けるには、多数のクリップ１５Ａをそれぞれ取付孔９Ａ，１４Ａに嵌着する必要があるため、その取付作業が煩雑なものとならざるを得ない。   As described above, in order to attach the conventional spoiler 3A to the bumper 2A, it is necessary to fit a large number of clips 15A into the attachment holes 9A and 14A, respectively, so that the installation work must be complicated. .

しかも、スポイラー３Ａが硬質材料によって構成されているので、図９に二点鎖線で示すように、スポイラー３Ａの地上高を低くすると、道路の一般面よりも高さの高くなった路肩などの障害物１０Ａにスポイラー３Ａの下部が当ったとき、そのスポイラー３Ａとバンパー２Ａに大きな応力が発生し、これらが破損するおそれがある。スポイラー３Ａによる空力特性を向上させるために、スポイラー３Ａの高さ方向の幅ＨＡを大きくして、そのスポイラー３Ａの地上高を図９に二点鎖線で示したように低くすることが望ましいのであるが、このようにすると、スポイラー３Ａとバンパー２Ａが上述のように破損するおそれがあるので、図９に示すように、スポイラー３Ａの高さ方向の幅ＨＢを小さくせざるを得なかったのである。   Moreover, since the spoiler 3A is made of a hard material, as shown by a two-dot chain line in FIG. 9, when the ground height of the spoiler 3A is lowered, obstacles such as a shoulder that is higher than the general plane of the road. When the lower part of the spoiler 3A hits the object 10A, a large stress is generated in the spoiler 3A and the bumper 2A, which may be damaged. In order to improve the aerodynamic characteristics of the spoiler 3A, it is desirable that the width HA in the height direction of the spoiler 3A is increased so that the ground height of the spoiler 3A is lowered as shown by a two-dot chain line in FIG. However, if this is done, the spoiler 3A and the bumper 2A may be damaged as described above. Therefore, as shown in FIG. 9, the width HB in the height direction of the spoiler 3A has to be reduced. .

また、従来のスポイラー３Ａは硬質材料により構成されているので、或る型式の自動車用のスポイラーを他の型式の自動車に流用することは難しく、汎用性に劣る欠点を有していた。   In addition, since the conventional spoiler 3A is made of a hard material, it is difficult to divert a certain type of automobile spoiler to another type of automobile, and there is a disadvantage that it is inferior in versatility.

特開２００５−６７３０８号公報JP 2005-67308 A

本発明の目的は、上記従来の欠点を除去した自動車のスポイラーを提供することにある。   An object of the present invention is to provide an automobile spoiler that eliminates the above-mentioned conventional drawbacks.

本発明に係る自動車のスポイラーは、軟質弾性材料より成るスポイラー本体と、該スポイラー本体の上部に一体に固着されていて、車体に取り付けられたバンパーに形成された複数の取付孔にそれぞれ嵌着される複数の取付部とを有し、該取付部は、前記スポイラー本体よりも硬質な材料により構成されていることを特徴とする。   An automobile spoiler according to the present invention is integrally fixed to a spoiler body made of a soft elastic material and an upper portion of the spoiler body, and is fitted into a plurality of attachment holes formed in a bumper attached to a vehicle body. A plurality of attachment portions, and the attachment portions are made of a material harder than the spoiler body.

その際、前記スポイラー本体の上部の縁部に前記バンパーに密着するリップを形成することもできる。   At this time, a lip that is in close contact with the bumper may be formed at the upper edge of the spoiler body.

また、上記各自動車のスポイラーにおいて、前記スポイラー本体内に補強用のインサートを埋設することもできる。   Further, in the spoiler of each of the above automobiles, a reinforcing insert can be embedded in the spoiler body.

本発明によれば、クリップを用いることなく簡単にスポイラーをバンパーに取り付けることができる。   According to the present invention, a spoiler can be easily attached to a bumper without using a clip.

しかも、スポイラー本体が軟質弾性材料により構成されているので、そのスポイラー本体が障害物に当っても、該スポイラーが弾性変形する。このため、スポイラーとバンパーに大きな応力が発生することはなく、当該スポイラーとバンパーが破損することはない。このため、スポイラーの地上高を低くして、スポイラーによる空力特性を高めることができる。   Moreover, since the spoiler body is made of a soft elastic material, even if the spoiler body hits an obstacle, the spoiler is elastically deformed. Therefore, no great stress is generated in the spoiler and the bumper, and the spoiler and the bumper are not damaged. For this reason, the ground height of a spoiler can be made low and the aerodynamic characteristic by a spoiler can be improved.

さらに、本発明に係るスポイラーの本体は軟質弾性材料より成るので、そのスポイラーを装着する自動車の形態に応じてスポイラー本体を容易に弾性変形させることができる。このため、スポイラーを各種型式の自動車に装着することができる。   Furthermore, since the main body of the spoiler according to the present invention is made of a soft elastic material, the spoiler main body can be easily elastically deformed according to the form of the automobile on which the spoiler is mounted. For this reason, the spoiler can be mounted on various types of automobiles.

以下、本発明の実施形態例を図面に従って詳細に説明する。   Embodiments of the present invention will be described below in detail with reference to the drawings.

図１は、自動車の車体１の前部に取り付けられた前側のバンパー２にスポイラー３を装着した状態を示す斜視図であり、図２は図１のII−II線拡大断面図である。また図３は図１に示したスポイラー３をバンパー２に取り付ける前の様子を示す斜視図であり、図４は図３の部分拡大図である。   FIG. 1 is a perspective view showing a state in which a spoiler 3 is mounted on a front bumper 2 attached to a front portion of a vehicle body 1 of an automobile, and FIG. 2 is an enlarged sectional view taken along line II-II in FIG. 3 is a perspective view showing a state before the spoiler 3 shown in FIG. 1 is attached to the bumper 2, and FIG. 4 is a partially enlarged view of FIG.

図１乃至図４に示すように、本例の自動車のスポイラー３は、これがバンパー２に取り付けられたとき、車体１の車幅方向Ｗに延びるスポイラー本体４と、そのスポイラー本体４の上部に一体に固着された複数の取付部５とにより構成されている。複数の取付部５はスポイラー本体４の上部より上方に突出した突部として構成されている。   As shown in FIGS. 1 to 4, the spoiler 3 of the automobile according to the present embodiment is integrated with a spoiler body 4 extending in the vehicle width direction W of the vehicle body 1 and an upper portion of the spoiler body 4 when the spoiler 3 is attached to the bumper 2. And a plurality of mounting portions 5 fixed to each other. The plurality of attachment portions 5 are configured as protrusions that protrude upward from the upper portion of the spoiler body 4.

スポイラー本体４は、軟質弾性材料、例えば加硫ゴムなどのエラストマーにより構成され、各取付部５は、スポイラー本体４よりも硬質な材料、例えばポリプロピレンなどの硬質樹脂、或いはアルミニウムなどの金属により構成されている。   The spoiler body 4 is made of a soft elastic material, for example, an elastomer such as vulcanized rubber, and each mounting portion 5 is made of a material harder than the spoiler body 4, for example, a hard resin such as polypropylene, or a metal such as aluminum. ing.

また、本例の取付部５は、図２に明示するように、基部６と、その基部６に一体に形成された一対の係止部７とから構成され、その各係止部７は、段状の爪８を有している。一方、バンパー２の下部には、図２及び図４に示すように、スポイラー３の各取り付け部５に対応した位置に複数の取付孔９が形成されている。   Further, as shown in FIG. 2, the mounting portion 5 of this example includes a base portion 6 and a pair of locking portions 7 formed integrally with the base portion 6. It has a stepped claw 8. On the other hand, as shown in FIGS. 2 and 4, a plurality of attachment holes 9 are formed in the lower portion of the bumper 2 at positions corresponding to the attachment portions 5 of the spoiler 3.

上述したスポイラー３を、車体１に対して既に固定されているバンパー２に取り付けるには、図３に矢印Ａで示すように、スポイラー本体４をバンパー２の下部の形態に合せて弾性変形させ、そのスポイラー本体４の上部をバンパー２の下方にもたらし、次いでスポイラー本体４の上部に固着された各取付部５を、バンパー２の下部に形成された各取付孔９に下方から押し込む。このとき、各取付部５の一対の係止部７が、取付孔９の縁部から受ける外力によって互いに接近する向きに弾性変形しながら、各取付孔９に挿入され、図２に示したように、各係止部７の爪８が各取付孔９の縁部に係合する。このとき一対の係止部７は元の形態に弾性復帰する。このようにして、各取付部５の爪８が各取付孔９の縁部に係合することによりスポイラー３がバンパー２に取り付けられる。   In order to attach the above-described spoiler 3 to the bumper 2 that is already fixed to the vehicle body 1, as shown by an arrow A in FIG. 3, the spoiler body 4 is elastically deformed according to the form of the lower portion of the bumper 2, The upper part of the spoiler body 4 is brought below the bumper 2, and then the attachment parts 5 fixed to the upper part of the spoiler body 4 are pushed into the attachment holes 9 formed at the lower part of the bumper 2 from below. At this time, the pair of locking portions 7 of each mounting portion 5 is inserted into each mounting hole 9 while being elastically deformed in a direction approaching each other by an external force received from the edge of the mounting hole 9, as shown in FIG. Further, the claw 8 of each locking portion 7 engages with the edge portion of each mounting hole 9. At this time, the pair of locking portions 7 are elastically restored to the original form. In this way, the spoiler 3 is attached to the bumper 2 by engaging the claw 8 of each attachment portion 5 with the edge portion of each attachment hole 9.

上述のように、本例のスポイラー３は、そのスポイラー本体４に複数の取付部５が一体に固着され、その各取付部５を、車体１に取り付けられたバンパー２に形成されている複数の取付孔９にそれぞれ嵌着して、スポイラー３をバンパー２に装着するように構成されている。このため、従来のスポイラーのように多数のクリップを用いてスポイラーをバンパーに取り付ける必要はない。工具などを用いることなく、簡単にスポイラー３をバンパー２に取り付けることができるのである。   As described above, in the spoiler 3 of this example, a plurality of attachment portions 5 are integrally fixed to the spoiler body 4, and each of the attachment portions 5 is formed on the bumper 2 attached to the vehicle body 1. The spoiler 3 is mounted on the bumper 2 by being fitted into the mounting holes 9 respectively. For this reason, it is not necessary to attach a spoiler to a bumper using many clips like the conventional spoiler. The spoiler 3 can be easily attached to the bumper 2 without using a tool or the like.

また、スポイラー本体４が軟質弾性材料により構成されているので、スポイラー本体４が図示していない障害物に当って、図２に矢印Ｆで示した外力を受けても、そのスポイラー本体４は図２に二点鎖線で示すように弾性変形するだけで、スポイラー本体４とバンパー２に過大な応力が発生することはなく、これらが破損することを防止できる。従って、図２に示すように、スポイラー本体４の高さ方向の幅Ｈを従来よりも大きくして、スポイラー３の地上高を低くすることができる。これによりスポイラー３による空力特性を高めることができる。   Further, since the spoiler body 4 is made of a soft elastic material, even if the spoiler body 4 hits an obstacle (not shown) and receives an external force indicated by an arrow F in FIG. By simply elastically deforming as shown by a two-dot chain line in FIG. 2, excessive stress is not generated in the spoiler body 4 and the bumper 2, and they can be prevented from being damaged. Therefore, as shown in FIG. 2, the height H of the spoiler body 4 in the height direction can be made larger than before, and the ground height of the spoiler 3 can be lowered. Thereby, the aerodynamic characteristic by the spoiler 3 can be improved.

さらに、スポイラー本体４が軟質弾性材料により構成されているので、図３に示した形態以外のバンパーを有する自動車にも、そのバンパーの形態に合せてスポイラー本体４を弾性変形させて、該スポイラー３をその自動車に取り付けることができる。また、必要に応じて、スポイラー本体４をバンパーの形態に合せてカットしたり、バンパーに取付孔を追加することにより、スポイラー３を広範囲の型式の自動車に対して装着することが可能である。   Further, since the spoiler body 4 is made of a soft elastic material, an automobile having a bumper other than the form shown in FIG. 3 is also elastically deformed in accordance with the form of the bumper. Can be attached to the car. Further, if necessary, the spoiler 3 can be mounted on a wide range of types of vehicles by cutting the spoiler body 4 according to the form of the bumper or adding an attachment hole to the bumper.

また、図２に示すように、本例のスポイラー３においては、そのスポイラー本体４の上部の縁部に、バンパー２の下面に密着するリップ１１が形成されている。このため、バンパー２の厚さＴが多少異なっている場合でも、その各厚さのバンパー２にスポイラー３をがたつくことなく、取り付けることができる。すなわち、図２に示すように、バンパー２の厚さＴが比較的薄い場合にも、リップ１１がバンパー２の下面に密着するので、スポイラー３をがたつくことなくそのバンパー２に取り付けることができる。逆に、図５に示すように、バンパー２の厚さＴが比較的厚い場合も、これに応じてリップ１１が弾性変形して、バンパー２の下面に密着するので、スポイラー３を支障なく、そのバンパー２に取り付けることができる。   As shown in FIG. 2, in the spoiler 3 of this example, a lip 11 that is in close contact with the lower surface of the bumper 2 is formed at the upper edge of the spoiler body 4. For this reason, even when the thickness T of the bumper 2 is slightly different, the spoiler 3 can be attached to the bumper 2 of each thickness without rattling. That is, as shown in FIG. 2, even when the thickness T of the bumper 2 is relatively thin, the lip 11 is in close contact with the lower surface of the bumper 2, so that the spoiler 3 can be attached to the bumper 2 without rattling. On the contrary, as shown in FIG. 5, even when the thickness T of the bumper 2 is relatively thick, the lip 11 is elastically deformed in accordance with this and adheres closely to the lower surface of the bumper 2, so that the spoiler 3 is not hindered. It can be attached to the bumper 2.

さらに、図２に示したように、本例のスポイラー３においては、そのスポイラー本体４内に硬質樹脂板又は金属板などから成る補強用のインサート１２が埋設されている。これにより、スポイラー３に適度な剛性を付与することができるので、スポイラー３が自動車の走行時に風圧などによって過度に弾性変形して、空力特性が低下する不具合を阻止することができる。   Further, as shown in FIG. 2, in the spoiler 3 of this example, a reinforcing insert 12 made of a hard resin plate or a metal plate is embedded in the spoiler body 4. As a result, moderate rigidity can be imparted to the spoiler 3, so that it is possible to prevent the spoiler 3 from being excessively elastically deformed by wind pressure or the like when the automobile is running, thereby reducing the aerodynamic characteristics.

また、本例のスポイラー３は、例えば射出成形によって簡単に製造することができる。すなわち、予め成形して得た各取付部５を成形型にセットし、次いでスポイラー本体４用の溶融材料を成形型に注入することにより、スポイラー本体４に各取付部５が固着されたスポイラー３を製造することができる。   Moreover, the spoiler 3 of this example can be easily manufactured by injection molding, for example. That is, the spoiler 3 in which each mounting portion 5 is fixed to the spoiler body 4 by setting each mounting portion 5 obtained by molding in advance into a molding die and then injecting a molten material for the spoiler body 4 into the molding die. Can be manufactured.

さらに、図６に示すように、軟質弾性材料より成るスポイラー本体４と、このスポイラー本体４に一体の硬質材料より成る取付相当部１３を押出成形機によって成形し、次いで取付相当部１３の内の符号Ｂで示した不要部分をカットすることによって、図４に示したスポイラー３と同じスポイラーを製造することもできる。取付相当部１３の不要部分Ｂ以外の部分が取付部５として残されるのである。その際、取付相当部１３をカットする部分を適宜選択することによって、完成したスポイラー３の取付部５の位置を自由に設定することができる。   Further, as shown in FIG. 6, a spoiler body 4 made of a soft elastic material and an attachment equivalent portion 13 made of a hard material integral with the spoiler body 4 are formed by an extrusion molding machine. By cutting the unnecessary portion indicated by the symbol B, the same spoiler as the spoiler 3 shown in FIG. 4 can be manufactured. A portion other than the unnecessary portion B of the attachment equivalent portion 13 is left as the attachment portion 5. In that case, the position of the attachment part 5 of the completed spoiler 3 can be freely set by appropriately selecting a part to cut the attachment equivalent part 13.

また、図７に示すように、取付部５の横断面形状を円形とし、バンパー２に形成された取付孔９も円形に形成すると、バンパー２に、ドリルなどによって、後加工で容易に取付孔９を形成できるので、既に使用している自動車にも、容易にスポイラー３を取り付けることができる。   Also, as shown in FIG. 7, when the mounting section 5 has a circular cross-sectional shape and the mounting hole 9 formed in the bumper 2 is also formed in a circular shape, the mounting hole 5 can be easily mounted by post-processing on the bumper 2 by a drill or the like. 9 can be formed, the spoiler 3 can be easily attached to an automobile already used.

以上、車体１の前部に設けられたバンパー２に取り付けられるスポイラー３の例を説明したが、本発明は、車体後部に設けられたバンパーに取り付けられるスポイラーにも適用できるものである。   The example of the spoiler 3 attached to the bumper 2 provided at the front portion of the vehicle body 1 has been described above, but the present invention can also be applied to a spoiler attached to the bumper provided at the rear portion of the vehicle body.
