Description

本発明は、車両用のヘッドアップディスプレイ装置（以下、「ＨＵＤ装置」という）に関する。   The present invention relates to a head-up display device for vehicles (hereinafter referred to as “HUD device”).

従来、車両情報を表す発光像を投射口から車両のフロントウインドシールドへ投射することにより、当該発光像の虚像を表示させるＨＵＤ装置が、知られている。一般に、ＨＵＤ装置の投射口は、車両においてフロントウインドシールと向き合うインストルメントパネルの上面に開口させられるため、当該上面の見栄えを低下させることが懸念される。   Conventionally, a HUD device that displays a virtual image of a light emission image by projecting a light emission image representing vehicle information from a projection port to a front windshield of the vehicle is known. Generally, since the projection port of the HUD device is opened on the upper surface of the instrument panel facing the front wind seal in the vehicle, there is a concern that the appearance of the upper surface may be lowered.

そこで、特許文献１には、インストルメントパネルの上面に開口するデフロスタグリル内において、フロントウインドシールドに吹き付ける空気が流通するデフロスタ通路に対し、投射口を並んで配設させたＨＵＤ装置が、開示されている。このようにしてデフロスタ通路と並ぶことで投射口がデフロスタグリル内に収められることによれば、インストルメントパネル上面の見栄えを損なうことないので、車両内の意匠性を高め得るのである。   Therefore, Patent Document 1 discloses a HUD device in which projection ports are arranged side by side with respect to a defroster passage through which air blown to a front windshield circulates in a defroster grill opened on the upper surface of an instrument panel. ing. If the projection port is accommodated in the defroster grill by being aligned with the defroster passage in this manner, the appearance of the upper surface of the instrument panel is not impaired, and the design in the vehicle can be improved.

特開平１１−３４６５２号公報JP 11-34652 A

しかし、特許文献１に開示のＨＵＤ装置において投射口は、デフロスタグリル内にて車幅方向にデフロスタ通路と並んで配設されているため、フロントウインドシールドのうち投射口からの発光像の投射領域に対して、デフロスタ通路の出口部を向き合わせることができない。こうした構成では、デフロスタ通路の流通空気を投射領域に吹き付けて曇りを防止及び除去することが困難となるため、当該曇りの領域に投射された発光像の虚像表示は不鮮明となり、車両情報の視認性の低下を招いてしまうおそれがあった。   However, in the HUD device disclosed in Patent Document 1, since the projection port is arranged in the defroster grille along with the defroster passage in the vehicle width direction, the projection area of the light emission image from the projection port in the front windshield On the other hand, the exit part of a defroster channel | path cannot be faced. In such a configuration, it is difficult to prevent and remove fogging by blowing the circulating air in the defroster passage to the projection area, so that the virtual image display of the luminescent image projected on the cloudy area becomes unclear and the visibility of the vehicle information There was a risk of lowering.

本発明は、以上説明した問題に鑑みてなされたものであって、その目的は、車両情報の判読性と車両内の意匠性とを共に高めたＨＵＤ装置を、提供することにある。   The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a HUD device that enhances both the legibility of vehicle information and the design in the vehicle.

請求項１に記載の発明は、発光像を投射口から車両のフロントウインドシールドへ投射することにより、当該発光像の虚像を表示させるＨＵＤ装置であって、車両のインストルメントパネルの上面に開口するデフロスタグリル内において、フロントウインドシールドに吹き付ける空気が流通するデフロスタ通路に対し、投射口が車両の前後方向に並んで配設されるヘッドアップディスプレイ装置は、フロントウインドシールドのうち発光像の投射領域側へ向かってデフロスタ通路の流通空気を整流する整流板により、車幅方向に複数区画に仕切られるデフロスタグリル内において、整流板の間の各区画毎にデフロスタ通路及び投射口が個別に配設されるように、複数設置されることを特徴とする。 The invention according to claim 1 is a HUD device that displays a virtual image of the light emission image by projecting the light emission image from the projection port to the front windshield of the vehicle, and opens to the upper surface of the instrument panel of the vehicle. In the defroster grill, the head-up display device in which the projection ports are arranged in the front-rear direction of the vehicle with respect to the defroster passage through which the air blown to the front windshield circulates is the projection area side of the luminescent image in the front windshield In the defroster grill divided into a plurality of compartments in the vehicle width direction by the rectifying plate that rectifies the circulating air in the defroster passage toward the defroster passage, the defroster passage and the projection port are individually arranged for each compartment between the rectifying plates. A plurality of installations are provided.

この発明によると、インストルメントパネル上面に開口するデフロスタグリル内において、車両前後方向にＨＵＤ装置の投射口と並ぶデフロスタ通路の出口部は、フロントウインドシールドのうち当該投射口からの発光像の投射領域に対して、向き合い得る。これによれば、投射領域にデフロスタ通路の流通空気が吹き付けられて、曇りの防止作用乃至は除去作用が発揮されることになるので、当該領域に投射された発光像の虚像表示を鮮明なものとして、車両情報の判読性を高めることができる。しかも、投射口がデフロスタ通路と並ぶことでデフロスタグリル内に収められることによれば、インストルメントパネル上面の見栄えを損なうことがないので、車両内の意匠性を高めることもできるのである。   According to the present invention, in the defroster grille opened on the top surface of the instrument panel, the exit portion of the defroster passage aligned with the projection port of the HUD device in the vehicle front-rear direction is the projection region of the light emission image from the projection port of the front windshield. Can face each other. According to this, since the circulation air of the defroster passage is blown to the projection area, and the anti-fogging action or the removal action is exhibited, the virtual image display of the luminescent image projected on the area is clear. As a result, the legibility of vehicle information can be improved. Moreover, if the projection opening is accommodated in the defroster grill by being aligned with the defroster passage, the appearance of the top surface of the instrument panel is not impaired, and the design in the vehicle can be improved.

また、請求項１に記載の発明のように、デフロスタグリル内を仕切る整流板により、フロントウインドシールドのうち発光像の投射領域側へ向かって整流されるデフロスタ通路の流通空気は、当該投射領域に確実に吹き付けられ得る。しかも、投射口が間に配設される整流板は、当該投射口の近くにて空気を整流し得るので、当該投射口からの発光像の投射領域に空気の吹き付け領域を正確に合わせ易い。これらによれば、投射領域の曇りに対する防止作用及び除去作用の発揮を確固たるものとして、虚像表示の鮮明さ、ひいては車両情報の判読性を高めることができるのである。  In addition, as in the first aspect of the present invention, the circulation air in the defroster passage that is rectified toward the projection area side of the light emission image in the front windshield by the rectifying plate that partitions the inside of the defroster grille is directed to the projection area. Can be reliably sprayed. In addition, since the rectifying plate with the projection opening disposed therebetween can rectify the air near the projection opening, it is easy to accurately match the air blowing area with the projection area of the luminescent image from the projection opening. According to these, it is possible to improve the clearness of the virtual image display and, consequently, the legibility of the vehicle information, as a firm effect of preventing and removing the clouding of the projection area.

請求項２に記載の発明は、投射口を形成するハウジングを備え、ハウジングの外面は、デフロスタ通路に露出することにより、フロントウインドシールドのうち発光像の投射領域側へ向かって当該デフロスタ通路の流通空気を整流する。この発明のように、デフロスタ通路が露出するハウジングの外面により、フロントウインドシールドのうち発光像の投射領域側へ向かって整流されるデフロスタ通路の流通空気は、当該投射領域に確実に吹き付けられ得る。しかも、投射口を形成するハウジングの外面は、当該投射口の近くにて空気を整流し得るので、当該投射口からの発光像の投射領域に空気の吹き付け領域を正確に合わせ易い。これらによれば、投射領域の曇りに対する防止作用及び除去作用の発揮を確固たるものとして、虚像表示の鮮明さ、ひいては車両情報の判読性を高めることができるのである。  The invention according to claim 2 includes a housing that forms a projection opening, and the outer surface of the housing is exposed to the defroster passage so that the flow of the defroster passage toward the projection region side of the luminescent image in the front windshield. Rectify air. As in the present invention, the circulating air in the defroster passage that is rectified toward the projection region side of the luminescent image in the front windshield can be reliably blown to the projection region by the outer surface of the housing where the defroster passage is exposed. In addition, since the outer surface of the housing forming the projection port can rectify air near the projection port, it is easy to accurately match the air blowing region with the projection region of the luminescent image from the projection port. According to these, it is possible to improve the clearness of the virtual image display and, consequently, the legibility of the vehicle information, as a firm effect of preventing and removing the clouding of the projection area.

請求項３に記載の発明によると、デフロスタグリル内において、インストルメントパネルの上面よりも下方に投射口が配設される。この発明のように、インストルメントパネル上面に開口するデフロスタグリル内にて当該上面よりも下方の投射口は、車両内の乗員により視認され難い。故に、インストルメントパネル上面の見栄え、ひいては車両内の意匠性を高めることができるのである。 According to the third aspect of the present invention, the projection port is disposed below the upper surface of the instrument panel in the defroster grill. As in the present invention, the projection port below the upper surface in the defroster grill that opens to the upper surface of the instrument panel is difficult to be visually recognized by a passenger in the vehicle. Therefore, the appearance of the upper surface of the instrument panel can be improved, and consequently the design in the vehicle can be improved.

（第一実施形態）
図１，２は、本発明の第一実施形態によるＨＵＤ装置１０の車両１への搭載状態を示している。 (First embodiment)
1 and 2 show a mounted state of the HUD device 10 according to the first embodiment of the present invention on the vehicle 1.

車両１内において運転席前方のインストルメントパネル２には、デフロスタグリル３が装着されている。樹脂により矩形筒状に形成されているデフロスタグリル３は、インストルメントパネル２の上面２ａのうち車両１のフロントウインドシールド４と向き合う箇所に、開口している。デフロスタグリル３内は、車幅方向に所定間隔をあけて並ぶ複数の整流板３ａにより、仕切られている。デフロスタグリル３内において各整流板３ａ間には、車両のデフロスタダクト５と連通するデフロスタ通路６が、それぞれ個別に形成されている。ここで特に本実施形態では、各整流板３ａの表面を含むデフロスタグリル３の内面３ｂにより、各デフロスタ通路６の全体が区画されている。   A defroster grill 3 is mounted on an instrument panel 2 in front of the driver's seat in the vehicle 1. The defroster grill 3 formed in a rectangular cylindrical shape with resin is opened at a position facing the front windshield 4 of the vehicle 1 on the upper surface 2 a of the instrument panel 2. The inside of the defroster grill 3 is partitioned by a plurality of rectifying plates 3a arranged at predetermined intervals in the vehicle width direction. In the defroster grill 3, defroster passages 6 communicating with the defroster ducts 5 of the vehicle are individually formed between the rectifying plates 3a. Here, particularly in the present embodiment, the entire defroster passage 6 is partitioned by the inner surface 3b of the defroster grill 3 including the surface of each rectifying plate 3a.

このような各デフロスタ通路６は、車両１の空調装置（図示しない）により温度調節されてデフロスタダクト５から送られてくる空気を、それら各デフロスタ通路６を挟む整流板３ａの表面に沿って流通させる。このとき各デフロスタ通路６の流通空気は、デフロスタグリル３の上方のフロントウインドシールド４のうち、それら各デフロスタ通路６の出口部６ａと向き合う領域側へ向かって整流されることにより、当該領域へと吹き付けられる。したがって、温度調節された空気の吹付領域においては、フロントウインドシールド４に曇りが生じるのを防止することや、フロントウインドシールド４の曇りが生じていても除去することが、できるのである。   Each such defroster passage 6 circulates the air sent from the defroster duct 5 with the temperature adjusted by an air conditioner (not shown) of the vehicle 1 along the surface of the rectifying plate 3 a sandwiching each defroster passage 6. Let At this time, the circulating air in each defroster passage 6 is rectified toward the region of the front windshield 4 above the defroster grill 3 that faces the outlet portion 6a of each defroster passage 6 to the region. Be sprayed. Therefore, in the temperature-controlled air blowing region, it is possible to prevent the front windshield 4 from being fogged or to remove even if the front windshield 4 is fogged.

車両１においてＨＵＤ装置１０は、デフロスタグリル３内のうち各デフロスタ通路６の後方に、それぞれ個別に設置されている。第一実施形態において各ＨＵＤ装置１０の構成は、実質的に互いに同一であるので、以下では、一つのＨＵＤ装置１０の構成を代表して説明する。   In the vehicle 1, the HUD device 10 is individually installed behind each defroster passage 6 in the defroster grill 3. In the first embodiment, the configuration of each HUD device 10 is substantially the same as each other, and therefore, the configuration of one HUD device 10 will be described as a representative.

ＨＵＤ装置１０は、ハウジング１１、光源１２及びカバーレンズ１３を備えている。樹脂により中空箱状に形成されているハウジング１１は、ＨＵＤ装置１０に対応するデフロスタ通路６の後方において、デフロスタグリル３に装着されている。ハウジング１１は、デフロスタグリル３内のうちインストルメントパネル２の上面２ａよりも下方においてフロントウインドシールド４と向き合う上部１１ａに、投射口１１ｂを形成している。これにより、本実施形態の投射口１１ｂは、デフロスタグリル３内において車両の前後方向にデフロスタ通路６と並ぶ形態に、且つインストルメントパネル２の上面２ａよりも下方に、配設されている。   The HUD device 10 includes a housing 11, a light source 12, and a cover lens 13. A housing 11 formed in a hollow box shape with resin is attached to the defroster grill 3 behind the defroster passage 6 corresponding to the HUD device 10. The housing 11 forms a projection port 11 b in an upper part 11 a facing the front windshield 4 below the upper surface 2 a of the instrument panel 2 in the defroster grill 3. Thereby, the projection port 11b of this embodiment is arrange | positioned in the form lined up with the defroster channel | path 6 in the front-back direction of a vehicle in the defroster grill 3, and below the upper surface 2a of the instrument panel 2. FIG.

光源１２は、本実施形態では発光ダイオード（ＬＥＤ）からなり、ハウジング１１の内部空間１１ｃに収容されている。光源１２は、車両１の表示制御回路（図示しない）により通電制御されて発光することで、所定色の光を出射する。樹脂により板状に形成されているカバーレンズ１３は、ハウジング１１の投射口１１ｂに装着されている。カバーレンズ１３は、所定の車両情報を図柄や文字等により表すインジケータを、形成している。図１の矢印の如く、カバーレンズ１３が光源１２からの出射光により透過照明されることで、インジケータの発光像が投射口１１ｂから上方のフロントウインドシールド４へ投射される。このとき特に本実施形態では、ＨＵＤ装置１０に対応するデフロスタ通路６を挟んだ整流板３ａが空気を整流する側に、フロントウインドシールド４における発光像の投射領域４ａが位置するようになっている。こうしてフロントウインドシールドに投影される発光像は、車両１において当該シールド４の前方にて結像されることで、図１の矢印の如く、虚像として運転席側へと向かって表示されることになる。   In this embodiment, the light source 12 is formed of a light emitting diode (LED), and is accommodated in the internal space 11 c of the housing 11. The light source 12 emits light of a predetermined color by being energized and controlled by a display control circuit (not shown) of the vehicle 1. The cover lens 13 formed in a plate shape with resin is attached to the projection port 11 b of the housing 11. The cover lens 13 forms an indicator that represents predetermined vehicle information by a pattern, characters, or the like. As the arrow of FIG. 1 shows, the cover lens 13 is transmitted and illuminated by the light emitted from the light source 12, so that the light emission image of the indicator is projected onto the upper front windshield 4 from the projection port 11b. At this time, particularly in the present embodiment, the projection region 4a of the luminescent image in the front windshield 4 is positioned on the side where the rectifying plate 3a sandwiching the defroster passage 6 corresponding to the HUD device 10 rectifies air. . The light emission image projected onto the front windshield in this manner is formed in front of the shield 4 in the vehicle 1 and is displayed as a virtual image toward the driver's seat as shown by the arrow in FIG. Become.

以上説明の第一実施形態によると、デフロスタグリル３内にて各ＨＵＤ装置１０の投射口１１ｂと車両前後方向に並ぶ各デフロスタ通路６の出口部６ａは、フロントウインドシールド４のうち、それら投射口１１ｂからの発光像の投射領域４ａに対して向き合う状態となる。これによれば、各ＨＵＤ装置１０による発光像の投射領域４ａに各デフロスタ通路６の流通空気が吹き付けられて、曇りの防止作用及び除去作用が発揮されることで、それら発光像の虚像表示が鮮明となるので、車両情報の判読性を高めることができるのである。   According to the first embodiment described above, the projection ports 11 b of the respective HUD devices 10 and the outlet portions 6 a of the defroster passages 6 arranged in the vehicle front-rear direction in the defroster grill 3 are the projection ports of the front windshield 4. It will be in the state which faces with respect to the projection area | region 4a of the light emission image from 11b. According to this, the circulation air of each defroster passage 6 is blown to the projection area 4a of the luminescent image by each HUD device 10, and the effect of fogging prevention and removal is exhibited, so that the virtual image display of these luminescent images is performed. Since it becomes clear, the legibility of vehicle information can be improved.

また、第一実施形態によると、デフロスタグリル３内の整流板３ａは、各ＨＵＤ装置１０による発光像の投射領域４ａ側へ向かって各デフロスタ通路６の流通空気を整流するので、それら投射領域４ａには、各デフロスタ通路６の流通空気が確実に吹き付けられ得る。しかも、投射口１１ｂが間に配設される各整流板３ａは、当該投射口１１ｂの近くにて空気を整流し得るので、当該投射口１１ｂからの発光像の投射領域４ａに空気の吹き付け領域を正確に合わせ易い。これらによれば、各ＨＵＤ装置１０による発光像の投射領域４ａの曇りに対して、防止作用及び除去作用の発現を確固たるものとして、虚像表示の鮮明さ、ひいては車両情報の判読性を高めることができるのである。   Moreover, according to 1st embodiment, since the baffle plate 3a in the defroster grill 3 rectifies | circulates the distribution | circulation air of each defroster channel | path 6 toward the projection area | region 4a side of the light emission image by each HUD apparatus 10, these projection area | regions 4a The circulating air in each defroster passage 6 can be reliably blown.

Can be given to. Therefore, in combination with the rectifying action by each rectifying plate 3a, the air flowing through each defroster passage 206 can be reliably blown to the projection area 4a of the luminescent image by each HUD device 210. In addition, since the outer surface 211d of the housing 211 that forms the projection port 11b in each HUD device 210 can rectify the air near the projection port 11b, air is projected into the projection region 4a of the luminescent image from the projection port 11b. It is easy to match the spray area accurately. According to these, it is possible to improve the clearness of the virtual image display and, consequently, the legibility of the vehicle information, with the positive effect of preventing and removing the clouding of the projection area 4a of the emission image by each HUD device 210. It can be done.
