Description
【０００１】[0001]
本考案は、自動車のバックミラーの構造に関する。 The present invention relates to a rearview mirror structure for an automobile.
【０００２】[0002]
周知のように、バックミラー後面には、走行風による渦流が発生し、そのため ミラー表面に水滴が付着して後方視界が妨げられる。 As is well known, a vortex is generated by the traveling wind on the rear surface of the rearview mirror, which causes water droplets to adhere to the surface of the mirror and hinder rearward visibility.
【０００３】 上記水滴の付着を防止するため図４に示すように、バックミラー１０の本体１ １の後縁の上部中央にワイパ１２を設け、ミラー１３の表面の水滴を除去する機 構が知られている。As shown in FIG. 4, in order to prevent the water droplets from adhering, a mechanism for removing water droplets on the surface of the mirror 13 by providing a wiper 12 at the upper center of the rear edge of the main body 11 of the rearview mirror 10 is known. Has been.
【０００４】[0004]
上記のワイパによる機構は、構造が複雑で高価であり、一部の高級車に用いら れているが、大衆車や貨物車、商業車には普及していない。また、実開昭５９− １５１７４６号公報にはバックミラー後面の渦流を防止するために、バックミラ ーの側面から走行風を導入する技術が示されている。しかしながら、この公知技 術では両側面から走行風を導入しているので、バックミラーの中心部は導入風が 達せず、水滴をふきとることはできない。 The wiper mechanism described above has a complicated structure and is expensive, and is used in some luxury vehicles, but it is not popular in mass vehicles, freight vehicles, and commercial vehicles. Further, Japanese Utility Model Laid-Open No. 59-151746 discloses a technique of introducing a running wind from the side surface of the back mirror in order to prevent a vortex flow on the rear surface of the rearview mirror. However, in this known technique, since the running wind is introduced from both sides, the introduced wind does not reach the central part of the rearview mirror and the water droplets cannot be wiped off.
【０００５】 本考案は、走行風を用いてバックミラー全面に付着した水滴を効果的に除去す る自動車のバックミラーの構造を提供することを目的としている。An object of the present invention is to provide a structure of an automobile rearview mirror that effectively removes water droplets attached to the entire surface of the rearview mirror by using traveling wind.
【０００６】[0006]
本考案によれば、バックミラー本体の一側に前方が開いて後方が狭くなってい る案内部材を設け、その案内部材の後端はバックミラー本体の鏡面に走行風を案 内する折り曲げ部を有している。 According to the present invention, a guide member whose front part is open and rear part is narrow is provided on one side of the rearview mirror body, and the rear end of the guide member has a bent portion on the mirror surface of the rearview mirror body that allows the traveling wind. Have
【０００７】 上記案内部材は、バックミラー本体と一体に形成するのが好ましいが、別体に 形成し、ステーにより既存のミラーに装着するようにしてもよい。Although the guide member is preferably formed integrally with the rearview mirror body, it may be formed as a separate body and attached to an existing mirror by a stay.
【０００８】[0008]
上記のように構成された自動車のバックミラーの構造において、走行風は案内 部材に案内されて鏡面に沿って流れ、そのときに水滴を除去する。ディフューザ 効果により鏡面に沿う流速が早くなり効果的である。 In the structure of the automobile rearview mirror configured as described above, the traveling wind is guided by the guide member and flows along the mirror surface, and at that time, water droplets are removed. The diffuser effect is effective because the flow velocity along the mirror surface becomes faster.
【０００９】[0009]
以下図面を参照して本考案の実施例を説明する。 An embodiment of the present invention will be described below with reference to the drawings.
【００１０】 図１及び図２において、バックミラー本体１のミラーカバー２の後縁部には、 ミラー９が嵌着されている。そのミラーカバー２の一側（図示の例では右側）に は、案内部材である整流板３が一体に形成されており、この整流板３で前面に開 口部４を備え、後方に向けて断面積が小さくなる整流溝５が画成されている。そ して、整流板３の後縁部６は、ミラー９の表面より突出され、ミラー９側に略直 角に折り曲げ形成されており、その後縁部６には、ミラー９側に向けた複数（図 示の例では７個）の吹き出し口７が形成されている。In FIGS. 1 and 2, a mirror 9 is fitted on the rear edge of the mirror cover 2 of the rearview mirror body 1. A rectifying plate 3 that is a guide member is integrally formed on one side of the mirror cover 2 (on the right side in the illustrated example). The rectifying plate 3 has an opening 4 on the front surface and faces rearward. A rectifying groove 5 having a small cross-sectional area is defined. The rear edge 6 of the rectifying plate 3 is projected from the surface of the mirror 9 and is bent to form a substantially right angle on the mirror 9 side. The rear edge 6 has a plurality of edges facing the mirror 9 side. (7 in the illustrated example) blowout ports 7 are formed.
【００１１】 したがって、開口部４から矢印ａのように流入した走行風は、後方に向けて断 面積が小さくなる整流溝５のディフューザー効果で流速が高められ、吹き出し口 ７からミラー９の表面に沿って高速で吹き出される。そのため、ミラー９の全表 面付着した水滴は、すべて確実に吹き飛ばされ除去される。Therefore, the traveling wind that has flowed in from the opening 4 as shown by the arrow a has a higher flow velocity due to the diffuser effect of the straightening groove 5 having a smaller cross-sectional area toward the rear, and flows from the outlet 7 to the surface of the mirror 9. It is blown out at high speed. Therefore, all the water droplets attached to the entire surface of the mirror 9 are surely blown off and removed.
【００１２】 図３は本考案の別の実施例を示し、このバックミラー１Ａでは案内部材を前記 整流板３と略同形で別体の整流板３Ａで形成し、ステー８ａ、８ｂでミラーカバ ー２Ａに取付け、開口部４Ａ、整流溝５Ａ及び吹き出しスリット７Ａを画成した 例である。この実施例では、前記と同様の作用効果を奏するほか、既存のバック ミラーに簡単に実施することができる。FIG. 3 shows another embodiment of the present invention. In this rearview mirror 1A, the guide member is formed of a separate flow straightening plate 3A having substantially the same shape as the flow straightening plate 3, and the stays 8a and 8b are provided with a mirror cover 2A. It is an example in which the opening 4A, the rectifying groove 5A, and the blowing slit 7A are defined by being attached to the. In this embodiment, in addition to the same effects as the above, the present invention can be easily applied to an existing rearview mirror.
【００１３】[0013]
本考案は、以上説明したように構成されているので、構造簡単で安価な構造で 走行風を利用しバックミラー全面に付着した水滴を効果的に除去することができ る。 Since the present invention is configured as described above, it is possible to effectively remove water droplets adhering to the entire surface of the rearview mirror by using traveling wind with a simple and inexpensive structure.
