Description

この発明は、車両の走行によって受ける風をドアミラーの表面に誘導して吹きつけ、ドアミラーの表面に付着した水滴を速やかに除去できるドアミラーに関する。   The present invention relates to a door mirror that can guide and blow wind received by traveling of a vehicle to the surface of a door mirror and quickly remove water droplets attached to the surface of the door mirror.

従来、外部から取り入れた空気がドアミラー表面への空気吹き出し口につながる空気誘導通路に入る前の段階で雨水を分離し、空気誘導通路にはごくわずかな雨水しか入らないようにすることによって、効率よくドアミラー表面に付着した水滴を除去できるドアミラーが考案されている。(例えば、特許文献1参照。) Conventionally, rainwater is separated before entering the air induction passage where the air taken from the outside leads to the air outlet to the door mirror surface, so that only a small amount of rainwater enters the air induction passage. A door mirror that can remove water droplets well attached to the surface of the door mirror has been devised. (For example, see Patent Document 1.)

これは、雨水を開口部の正面の壁面又は雨水付着板に付着させ、開口部から取り入れた空気の一部を使って、雨水排出通路内を吹送してドアミラー本体の側面又は下面の雨水排出口からドアミラー本体外に排出するものであるが、空気及び雨水が効率よく雨水排出通路を通過する必要がある。   This is because rainwater is attached to the front wall of the opening or the rainwater adhering plate, and a part of the air taken in from the opening is used to blow through the rainwater discharge passage to open the rainwater outlet on the side or bottom of the door mirror body. However, air and rainwater must pass through the rainwater discharge passage efficiently.

本発明(請求項1)のドアミラーは、車両の走行により空気を取り入れるための走行方向に開いた開口部、開口部から取り入れた空気を空気分流仕切りで空気誘導通路と雨水排出通路に分流する構造、空気とともに取り入れた雨水を開口部の正面の壁面に付着させる構造、その雨水を開口部から取り入れ雨水排出通路に分流された空気で吹送しドアミラー本体の側面外部に排出する構造、ドアミラー側面を流れる空気が雨水排出口の走行方向側の突起から雨水排出口の走行方向とは反対側まで覆い、内側になる雨水排出口の気圧が相対的に低くなる円弧を描いて流れるように曲げるために雨水排出口の走行方向側で雨水排出口に接してドアミラー本体外側に設けた突起及び雨水を取り除いた空気を空気誘導通路を経由してミラー表面方向に開口した空気吹き出し口からミラー表面に吹き付ける構造を有する構成とした。 The door mirror of the present invention (Claim 1) has an opening that opens in the running direction for taking in air by running of the vehicle, and a structure that diverts the air taken in from the opening into an air induction passage and a rainwater discharge passage by an air shunting partition. A structure that attaches rainwater taken together with air to the wall surface in front of the opening, a structure that blows in rainwater from the opening and diverts it into the rainwater discharge passage, and discharges it outside the side surface of the door mirror body. To bend so that the air flows from a projection on the running direction side of the rainwater outlet to the opposite side of the running direction of the rainwater outlet and flows in a circular arc in which the pressure of the rainwater outlet on the inside becomes relatively low the air removing protrusions and rainwater provided outside the door mirror body in contact with rainwater discharge port mirror surface direction through the air induction passage running direction of the rainwater discharge port And configured to have a structure which blows from the mouth air outlet on the mirror surface.

本発明(請求項2)のドアミラーは、車両の走行により空気を取り入れるための走行方向に開いた開口部、開口部から取り入れた空気を空気誘導通路と雨水排出通路に分流する構造、空気とともに取り入れた雨水を開口部の正面に設けた雨水付着板に付着させる構造、その雨水を開口部から取り入れた空気で雨水排出通路に吹送し、さらに、ドアミラー本体の下面外部に排出する構造、ドアミラー下面を流れる空気が雨水排出口の走行方向側の突起から雨水排出口の走行方向とは反対側まで覆い、内側になる雨水排出口の気圧が相対的に低くなる円弧を描いて流れるように曲げるために雨水排出口の走行方向側で雨水排出口に接してドアミラー本体外側に設けた突起及び雨水を取り除いた空気を空気誘導通路を経由してミラー表面方向に開口した空気吹き出し口からミラー表面に吹き付ける構造を有する構成とした。 The door mirror of the present invention (Claim 2) has an opening that is opened in the running direction for taking in air by running the vehicle, a structure that diverts the air taken in from the opening into the air induction passage and the rainwater discharge passage, and takes in together with the air A structure that attaches rainwater to a rainwater adhesion plate provided in front of the opening, a structure in which the rainwater is blown into the rainwater discharge passage with air taken in from the opening, and is further discharged to the outside of the lower surface of the door mirror body. Because the flowing air covers from the projection on the running direction side of the rainwater discharge port to the side opposite to the running direction of the rainwater discharge port, and bends so as to flow in an arc where the atmospheric pressure of the rainwater discharge port on the inside is relatively low open the air by removing the protrusion and rainwater provided outside the door mirror body in contact with rainwater outlet in the running direction of the rainwater discharge port through the air induction passage on the mirror surface direction And configured to have a structure which blows from the air outlet on the mirror surface.

雨水排出口の走行方向側に設けられた突起により、ドアミラー本体の外部を流れる空気が雨水排出口の走行方向側の突起から雨水排出口の走行方向とは反対側までを覆う円弧を描いて流れることにより、流線曲率の定理により円弧の内側になる雨水排出口の気圧が相対的に低くなり、雨水排出通路から雨水排出口に向かう空気の流れが強められる。 Due to the protrusion on the running direction side of the rainwater discharge port, the air flowing outside the door mirror body flows in an arc that covers from the protrusion on the running direction side of the rainwater discharge port to the side opposite to the running direction of the rainwater discharge port. As a result, the atmospheric pressure of the rainwater discharge port located inside the arc is relatively lowered by the streamline curvature theorem, and the air flow from the rainwater discharge passage toward the rainwater discharge port is strengthened.

以下、本発明の実施の形態を図1〜図8に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to FIGS.

走行中の車両は、前面から風を受けるが、ドアミラーも同様に前面から風を受ける。空気取り入れ口3の前方から来る空気は、ドアミラー本体1の中に入り、空気誘導通路6又は雨水排出通路7のいずれかを経由して空気吹き出し口8か雨水排出口9のいずれかからドアミラー本体1の外部に排出される。空気吹き出し口8は、ミラー10の表面に向いており、ミラー10の表面の水滴を吹き飛ばすか速やかに蒸発させて除去する。   A running vehicle receives wind from the front, but a door mirror receives wind from the front as well. Air coming from the front of the air intake 3 enters the door mirror main body 1, and passes through either the air guide passage 6 or the rainwater discharge passage 7 from either the air outlet 8 or the rainwater discharge port 9. 1 is discharged to the outside. The air outlet 8 faces the surface of the mirror 10 and removes water droplets on the surface of the mirror 10 by blowing off or quickly evaporating.

降雨時には、空気とともに雨滴が空気取り入れ口3からドアミラー本体1の中に入るが、雨滴は空気に比べて重いので大半の雨滴は慣性力により空気取り入れ口3の正面の雨水付着壁4又は雨水付着板11に付着する。雨水付着壁4又は雨水付着板11に付着した雨滴は、空気取り入れ口3から取り入れられた空気の一部によって雨水排出通路7に吹送され、ミラー本体1の側面又は下面に設けられた雨水排出口9からミラー本体1の外に排出される。大半の雨水が除去された空気が空気誘導通路6を経由して空気吹き出し口8に送られる。   When it rains, raindrops enter the door mirror body 1 from the air intake 3 together with air, but since raindrops are heavier than air, most raindrops adhere to the rainwater adhering wall 4 or rainwater adhering to the front of the air intake 3 due to inertia. It adheres to the plate 11. Raindrops adhering to the rainwater adhering wall 4 or the rainwater adhering plate 11 are blown into the rainwater discharge passage 7 by a part of the air taken in from the air intake 3, and are provided on the side surface or the lower surface of the mirror body 1. 9 is discharged out of the mirror body 1. The air from which most of the rainwater has been removed is sent to the air outlet 8 via the air guide passage 6.

雨水排出口9の走行方向側で雨水排出口9に接してドアミラー本体1の外側に設けられた突起15によってドアミラー本体1の外部を流れる空気は、図6又は図8のように、雨水排出口9の走行方向側の突起15から雨水排出口9の走行方向とは反対側までを覆う円弧を描いて流れる。流線が曲がるときには、流線の外側の圧力が高く内側の圧力が低くなるため、雨水排出通路7の中の雨水排出口9に向かう空気の流れが強められる。 Air by a projection 15 provided on the outside of the door mirror body 1 in contact with rainwater outlet 9 in the traveling direction of the rainwater discharge port 9 through the outside of the door mirror body 1, as shown in FIG. 6 or FIG. 8, rainwater outlet 9 flows in a circular arc covering from the projection 15 on the traveling direction side to the side opposite to the traveling direction of the rainwater discharge port 9 . When the streamline is bent, the pressure on the outside of the streamline is high and the pressure on the inside is low, so that the air flow toward the rainwater discharge port 9 in the rainwater discharge passage 7 is strengthened.
