Description
【０００１】
【発明の属する技術分野】
本発明は、自動車のドアミラーの化粧カバー部分に嵌着して使用するドアミラーカバーに関するものである。
【０００２】
【従来の技術】
ドアミラーを有する自動車においては、ドアミラーの付根部近辺で風切り音が発生することが知られている。殊に、フロントガラスと側窓との間に位置するＡピラー（側窓の前縁に沿って位置する前下がりに傾斜したピラー）に沿った前下がりのバイザー部分を有するサイドバイザーを装着した場合、その傾向が顕著である。これは、図６に示すように、自動車の走行時に、ドアミラー上を流れる気流Ｋ1が、ドアミラーの化粧カバー部分Ｂ（自動車メーカーにより予め車の一部として組み付けられている部分）の付根部によってドア側に押し曲げられ、ドア間の狭小な部位を勢い良く流れると共に、バイザー部分の先端部に当たる風量が増すためである。
【０００３】
【発明が解決しようとする課題】
上記の現状に鑑み、本発明は、ドアミラー上を流れる気流のうち、ドア側に押し曲げられる気流を減少させて、風切り音の発生を低減できるようにしたドアミラーカバーを提供するものである。
【０００４】
【課題を解決するための手段】
上記の課題を解決するために、本発明が講じた技術手段は、次のとおりである。即ち、本発明によるドアミラーカバーは、ドアミラーの化粧カバー部分に外嵌するように凹入した断面形状を有する内面板部と、それよりも前方へ突出し且つ上面が後ろ上がりに傾斜した断面形状を有する外面板部とを備えた中空構造のドアミラーカバーであって、前記外面板部におけるドアミラーの付根側の端部に立上がり面を形成し、当該立上がり面によって、走行時にドアミラー上を流れる気流がドア側に向かうのを抑制するように構成してあることを特徴としている。
【０００５】
上記の構成によれば、自動車の走行時に、ドアミラー上を流れる気流がドア側に向かうのをドアミラーカバー外面板部の立上がり面によって抑制するため、ドア側に向かう気流が減少し、ドアミラー付根部での風切り音の発生が低減されることになり、Ａピラーに沿った前下がりのバイザー部分を有するサイドバイザーを装着した場合に、特に効果的である。
【０００６】
【発明の実施の形態】
本発明の実施の形態を図面に基づいて説明すると、図１〜図５は、本発明に係るドアミラーカバーＡの一例を示す。このドアミラーカバーＡは、合成樹脂の成形品であって、ドアミラーの化粧カバー部分Ｂに外嵌するように凹入した断面形状を有する内面板部１と、それよりも前方へ突出し且つ上面が後ろ上がりに傾斜した断面形状を有する外面板部２とを備えた中空構造とされており、内面板部１をドアミラーの化粧カバー部分Ｂに略全面が密着する状態に外嵌させ、両面テープ等で接着して固定するようになっている。
【０００７】
前記外面板部２におけるドアミラーの付根側の端部には、立上がり面Ｓが形成されており、当該立上がり面Ｓによって、走行時にドアミラー上を流れる気流がドア側に向かうのを抑制するように構成されている。
【０００８】
尚、立上がり面Ｓは、自動車の進行方向に沿った平面状に形成してもよいが、図示の例では、後端側に行くにつれて外側に位置するような曲面状に形成されている。
【０００９】
上記の構成によれば、後ろ上がりに傾斜した外面板部２によって、ドアミラー背面側への空気の巻き込みを抑制して、ドアミラーの化粧カバー部分による空力特性を改善できるのみならず、自動車の走行時に、ドアミラー上を流れる気流がドア側に向かうのをドアミラーカバー外面板部２の立上がり面Ｓによって抑制することができるため、図５に示すように、ドアミラー上を流れる気流Ｋ1のうち、ドア側に向かう気流Ｋ2が極端に減少し、ドアミラー付根部での風切り音の発生を低減することが可能である。
【００１０】
また、ドアミラーカバーＡの内面板部１をドアミラーの化粧カバー部分Ｂに外嵌するように凹入した断面形状に形成してあるため、化粧カバー部分Ｂに対する接着面積が大きくて、強固な取付けが可能であり、しかも、ドアミラーカバーＡを中空構造に成形してあるので、全体を略均一な肉厚に成形して、成形直後の冷却時における合成樹脂のヒケによる変形を防止でき、且つ、全体の重量を軽減できる利点がある。
【００１１】
【発明の効果】
本発明は、上述した構成よりなるから、ドアミラー上を流れる気流のうち、ドア側に押し曲げられる気流を減少させて、風切り音の発生を低減できる効果がある。
【図面の簡単な説明】

BACKGROUND OF THE INVENTION
The present invention relates to a door mirror cover that is used by being fitted to a decorative cover portion of a door mirror of an automobile.
[0002]
[Prior art]
In an automobile having a door mirror, it is known that wind noise is generated near the root of the door mirror. In particular, when a side visor having a front-lowering visor portion along an A-pillar located between the windshield and the side window (a forward-tilting pillar positioned along the front edge of the side window) is mounted, The tendency is remarkable. This is because, as shown in FIG. 6, during running of the vehicle, the air flow K 1 flowing on the door mirror, the base portion of the door mirror of the decorative cover portion B (portion are assembled as part of the advance car by car manufacturers) This is because it is pushed and bent toward the door side and vigorously flows through a narrow portion between the doors, and the air volume hitting the tip of the visor portion increases.
[0003]
[Problems to be solved by the invention]
In view of the above-described present situation, the present invention provides a door mirror cover that can reduce the generation of wind noise by reducing the airflow that is pushed and bent to the door side out of the airflow that flows on the door mirror.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, the technical means taken by the present invention are as follows. That is, the door mirror cover according to the present invention has an inner surface plate portion having a cross-sectional shape that is recessed so as to be fitted on a decorative cover portion of the door mirror, and a cross-sectional shape that protrudes forward and the upper surface is inclined rearward and upward. A door mirror cover having a hollow structure provided with an outer surface plate portion, wherein a rising surface is formed at an end portion of the outer surface plate portion on a root side of the door mirror, and the rising surface allows an airflow flowing on the door mirror during traveling to the door side It is characterized by being configured to suppress heading to.
[0005]
According to the above configuration, the airflow flowing on the door mirror is prevented from moving toward the door side by the rising surface of the door mirror cover outer surface plate during driving of the automobile. This is particularly effective when a side visor having a front-lowering visor portion along the A pillar is attached.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. FIGS. 1 to 5 show an example of a door mirror cover A according to the present invention. The door mirror cover A is a synthetic resin molded product, and has an inner surface plate portion 1 having a cross-sectional shape that is recessed so as to be fitted on a decorative cover portion B of the door mirror, and protrudes further forward and has an upper surface at the back. It has a hollow structure including an outer
[0007]
A rising surface S is formed at the base end of the door mirror in the outer
[0008]
The rising surface S may be formed in a planar shape along the traveling direction of the automobile, but in the illustrated example, the rising surface S is formed in a curved shape that is located on the outer side as it goes to the rear end side.
[0009]
According to the above-described configuration, the outer
[0010]
Further, since the inner surface plate portion 1 of the door mirror cover A is formed in a cross-sectional shape that is recessed so as to be fitted around the decorative cover portion B of the door mirror, the adhesion area to the decorative cover portion B is large, and a firm attachment is possible. Moreover, since the door mirror cover A is formed in a hollow structure, the whole is formed into a substantially uniform thickness, and deformation due to sink marks of the synthetic resin during cooling immediately after molding can be prevented. There is an advantage that can reduce the weight.
[0011]
