Themirror device 1 includes a concave mirror 10 having a reflective film 11c formed on the front surface 11a of a substrate 11, and a case body 50 that supports the concave mirror 10 so that the reflection angle of the projection light L incident on the concave mirror 10 can be adjusted. The mirror device 1 includes a vibration damping body 20 that suppresses vibration of the concave mirror 10 by contacting the back surface 11 b of the substrate 11.
ミラー装置1は、基板11の前面11aに反射膜11cが形成された凹面鏡10と、凹面鏡10に入射される投影光Lの反射角度を調整可能に、凹面鏡10を支持するケース体50と、を有するミラー装置1であって、基板11の背面11bに接することで、凹面鏡10の振動を抑える制振体20を備えて構成される。 Next, the
The
凹面鏡10は、合成樹脂材料、例えばPC(ポリカーボネート)からなる基板11の前面11aの表面に、蒸着等の手段によりアルミニウム等の金属からなる反射膜11cを形成したものである。基板11は、前面11a及び裏側の背面11bがともに所定の曲率を有して前面11aが背面11bに向かって凹んだ凹状の曲面となっている。凹状の曲面を備えた基板11は、射出成形によって成形される。
凹面鏡10は、図2に示すように、前面11aから見た(正面視)した形状が横長の略矩形状に形成され、右辺の中央側から外側に突き出す軸部11dが基板11と一体に形成されている。左右の一直線上の軸部11d(左辺の軸部は図示せず)は、ケース体50に一体に形成された軸支部(図示せず)で回動可能に支持されている。一方の軸部11dには、図1に示すように、歯車11eが一体に形成され、ケース体50に取り付けたステッピングモータ11fのピニオン11gが噛み合っている。ステッピングモータ11fを駆動することで、ピニオン11gを介して歯車11eを回転することができ、凹面鏡10の角度を変えることができる。
これにより、凹面鏡10は、平面鏡80を介して入射される投影光Lの反射角度を調整することができる。つまり、フロントガラス70に対する投影光Lの出射方向を調整し、虚像Vの位置を運転者の視線に合わせることができる。 Theconcave mirror 10 is obtained by forming a reflective film 11c made of a metal such as aluminum on the front surface 11a of a substrate 11 made of a synthetic resin material such as PC (polycarbonate) by means of vapor deposition or the like. The substrate 11 has a concave curved surface in which both the front surface 11a and the back surface 11b have a predetermined curvature, and the front surface 11a is recessed toward the back surface 11b. The substrate 11 having a concave curved surface is formed by injection molding.
As shown in FIG. 2, theconcave mirror 10 is formed in a substantially rectangular shape when viewed from the front surface 11 a (front view), and a shaft portion 11 d that protrudes outward from the center side of the right side is formed integrally with the substrate 11. Has been. The left and right straight shaft portions 11 d (the left-hand shaft portion is not shown) are rotatably supported by a shaft support portion (not shown) formed integrally with the case body 50. As shown in FIG. 1, a gear 11 e is integrally formed with one shaft portion 11 d and a pinion 11 g of a stepping motor 11 f attached to the case body 50 is engaged. By driving the stepping motor 11f, the gear 11e can be rotated via the pinion 11g, and the angle of the concave mirror 10 can be changed.
Thereby, theconcave mirror 10 can adjust the reflection angle of the projection light L incident through the plane mirror 80. That is, the emission direction of the projection light L with respect to the windshield 70 can be adjusted to match the position of the virtual image V with the driver's line of sight.
凹面鏡10は、図2に示すように、前面11aから見た(正面視)した形状が横長の略矩形状に形成され、右辺の中央側から外側に突き出す軸部11dが基板11と一体に形成されている。左右の一直線上の軸部11d(左辺の軸部は図示せず)は、ケース体50に一体に形成された軸支部(図示せず)で回動可能に支持されている。一方の軸部11dには、図1に示すように、歯車11eが一体に形成され、ケース体50に取り付けたステッピングモータ11fのピニオン11gが噛み合っている。ステッピングモータ11fを駆動することで、ピニオン11gを介して歯車11eを回転することができ、凹面鏡10の角度を変えることができる。
これにより、凹面鏡10は、平面鏡80を介して入射される投影光Lの反射角度を調整することができる。つまり、フロントガラス70に対する投影光Lの出射方向を調整し、虚像Vの位置を運転者の視線に合わせることができる。 The
As shown in FIG. 2, the

制振体20は、基板11の背面11bに沿って形成されるとともに、基板11の背面11bに対して隙間を持って対面した状態で基板11に固定される、基板11より剛性の高い剛性板21と、剛性板21と基板11の背面11bとの間の隙間に位置する押え部材22と、を備える。
制振体20は、凹面鏡10の振動の発生を抑えるものであり、図3に示すように、凹面鏡10より剛性の高い材料、例えば、SPCC(冷間圧延鋼板)やSUS(ステンレス鋼)等の金属製の金属制振プレート(剛性板)21で形成されている。
凹面鏡10の振動は、基板11の両端部の軸部11dを支点として基板11が弓のように曲がる曲げ振動、2つの軸部11dを結ぶ直線を中心とする回転振動、軸部11dに沿う往復振動、の3つの振動が組み合わされて発生する。
デッドアップディスプレイ装置100では、特にミラー装置1の凹面鏡10の曲げ振動が問題となり、ヘッドアップディスプレイ装置100での虚像Vが前後にずれるようなぶれが発生する。 The damping body 20 is formed along theback surface 11b of the substrate 11 and is fixed to the substrate 11 in a state of facing the back surface 11b of the substrate 11 with a gap. 21 and a pressing member 22 positioned in a gap between the rigid plate 21 and the back surface 11 b of the substrate 11.
The damping body 20 suppresses the occurrence of vibration of theconcave mirror 10, and as shown in FIG. 3, a material having higher rigidity than the concave mirror 10, such as SPCC (cold rolled steel plate) or SUS (stainless steel), is used. It is formed of a metal damping plate (rigid plate) 21 made of metal.
The vibration of theconcave mirror 10 includes bending vibration in which the substrate 11 bends like a bow with the shaft portions 11d at both ends of the substrate 11 as fulcrums, rotational vibration about a straight line connecting the two shaft portions 11d, and reciprocation along the shaft portion 11d. The three vibrations are generated in combination.

なお、球面受け部33は、支持プレート33aとは別体に成形し、支持プレート33aの中心部に接着などで取り付けることもできる。
凹面鏡10の基板11の背面11bには、支持プレート33aを接着することで、球面受け部33が凹面鏡10の背面11bの中心部に設けられる。
球面受け部33には、ブラケット32の固定孔32aに固定された制振アーム31の球状部31cが接触した状態で当接される。 Aspherical receiving portion 33 that supports the spherical portion 31 c of the damping arm 31 is provided on the back surface 11 b of the substrate 11 of the concave mirror 10. The spherical surface receiving portion 33 has a concave spherical surface with which the convex spherical surface of the spherical portion 31c comes into contact, and is formed integrally with the central portion of the support plate 33a, for example, as shown in FIG.

図示しないケース体50に固定したブラケット32、凹面鏡10の基板11の背面11bの球面受け部33を、連結機構30の制振アーム31で連結することで、制振アーム31と球面受け部33により、凹面鏡10の基板11の背面11bが支持プレート33aの球面受け部33及び制振アーム31の球状部31cを介して図示しないケース体50に支持された状態となる。
これにより、凹面鏡10に発生する振動は、制振アーム31及びブラケット32を介して図示しないケース体50に伝達されて減衰され、振動が抑えられる。こうすることで、金属制振プレート21や樹脂制振プレート24の場合と同様に、例えば、シンバルなどの打楽器で振動して音が出ているときに、指を当てると、音(振動)が止まるのと同様にして、制振アーム31及びブラケット32で振動を抑えることができ、耐振動性を向上することができる

Thereby, the vibration generated in theconcave mirror 10 is transmitted to the case body 50 (not shown) via the damping arm 31 and the bracket 32 and is attenuated, thereby suppressing the vibration. By doing so, as in the case of the metal damping plate 21 and the resin damping plate 24, for example, when a sound is produced by vibrating with a percussion instrument such as a cymbal, the sound (vibration) is generated when the finger is applied. Similarly to stopping, vibration can be suppressed by the vibration control arm 31 and the bracket 32, and vibration resistance can be improved. Also, the concave mirror by providing the coupling mechanism 30 including the vibration control arm 31 and the bracket 32. The adjustment of the reflection angle of 10 can be permitted by being bent by the substantially S-shaped shape of the vibration control arm 31, and the angle can be adjusted without hindrance.
By bringing thespherical receiving portion 33 into contact with the back surface 11b of the substrate 11 of the concave mirror 10 via the supporting plate 33a, the supporting force is not concentrated on the portion of the spherical receiving portion 33, but is dispersed on the supporting plate 33a. It is possible to prevent the reflection film 11c from being distorted.
これにより、凹面鏡10に発生する振動は、制振アーム31及びブラケット32を介して図示しないケース体50に伝達されて減衰され、振動が抑えられる。こうすることで、金属制振プレート21や樹脂制振プレート24の場合と同様に、例えば、シンバルなどの打楽器で振動して音が出ているときに、指を当てると、音(振動)が止まるのと同様にして、制振アーム31及びブラケット32で振動を抑えることができ、耐振動性を向上することができる
また、制振アーム31及びブラケット32からなる連結機構30を設けることによる凹面鏡10の反射角度の調整は、制振アーム31の略S字状の形状によって撓むことで、許容することができ、支障なく角度調整を行うことができる。
凹面鏡10の基板11の背面11bに支持プレート33aを介して球面受け部33を当接させることで、球面受け部33の部分に支持力が集中することなく、支持プレート33aに分散され、凹面鏡10の反射膜11cのゆがみなどを防止することができる。 By connecting the

Thus, the vibration of the concave mirror 10 is transmitted to the highly rigid metal damping plate 21, and the vibration can be damped more reliably. Further, by abutting the presser member 22 against the central portion of the back surface 11b of the concave mirror 10, the antinodes of the amplitude of the vibration mode of the concave mirror 10 can be suppressed, and the vibration can be attenuated more effectively.
Further, by forming a rigid plate having a rigidity higher than that of thesubstrate 11 with the resin damping plate 24 made of synthetic resin, the vibration of the concave mirror 10 via the pressing member 25 is performed as in the case of the metal damping plate 21.

また、凹面鏡10自体に角度調整用の軸部を設けることなく、制振体20に軸部24cを設けることで、凹面鏡10の基板11と制振体20との材料を自由に選択することができ、それぞれに適した材料を用いることが可能となる。 According to the
