従来より、蛍光表示管等の発光型表示器が発した表示光を反射させて虚像を表示するヘッドアップディスプレイ装置が種々提案されており、例えば特許文献１に開示されている。ヘッドアップディスプレイ装置は、車両のダッシュボード１に配設されており、発光型表示器２が発した表示光Ｌを反射手段３に備えられる反射ミラー４で反射させて虚像Ｖを表示させるものである（図５参照）。反射手段３は、反射ミラー４が貼着される保持部材５を有しており、この保持部材５は回動可能な状態でハウジング６に支持され、反射手段３が開閉できる構成になっている（図６参照）。
実開昭６３−９０４１号公報 Conventionally, various head-up display devices that display a virtual image by reflecting display light emitted from a light-emitting display device such as a fluorescent display tube have been proposed. The head-up display device is disposed on the dashboard 1 of the vehicle, and displays the virtual image V by reflecting the display light L emitted from the light-emitting display device 2 with the reflection mirror 4 provided in the reflection means 3. Yes (see FIG. 5).

(See FIG. 6).
Japanese Utility Model Publication No. 63-9041

保持部材５には歯車７が固定されており、この歯車７にはモータ８の回動軸８ａに固定された歯車９が噛合されている。反射手段３は保持部材５の回動軸５ａを中心にして開閉できるようになっており、ヘッドアップディスプレイ装置を使用しない時には反射手段３を閉じておき、使用する時にモータ８の駆動力により反射手段３を所定の角度位置まで開くことができる。また、運転者の目の高さに応じて反射手段３の角度位置を調整するため、図示しない押ボタンスイッチの操作によってモータ８を駆動し、反射手段３を回動させることができる。   A gear 7 is fixed to the holding member 5, and a gear 9 fixed to the rotating shaft 8 a of the motor 8 is engaged with the gear 7.

以下、添付の図面に基づいて、本発明の一実施形態であるヘッドアップディスプレイ装置について説明する。なお、本実施形態における「右向き」或いは「左向き」とは、図１及び図２で図示した側面から見た方向である。   Hereinafter, a head-up display device according to an embodiment of the present invention will be described with reference to the accompanying drawings. Note that “rightward” or “leftward” in the present embodiment is a direction viewed from the side surface illustrated in FIGS. 1 and 2.

図１に示すように、ヘッドアップディスプレイ装置は、反射手段１０，第一の駆動手段（駆動手段）２０，第二の駆動手段（他の駆動手段）３０及びハウジング４０から主に構成されている。   As shown in FIG. 1, the head-up display device mainly includes a reflection means 10, a first drive means (drive means) 20, a second drive means (other drive means) 30, and a housing 40. .

The reflection mirror 11 is formed by depositing a reflective layer on a resin substrate made of polycarbonate, and reflects display light emitted from a light emitting display (not shown). The holding member 12 includes a base portion 12a, a shaft portion 12b that is pivotally supported by the housing 40, a holding portion 12c that adheres the reflection mirror 11, and a sliding portion 12d. In the sliding portion 12d, when the reflecting means 10 is opened to a predetermined angular position, the first recess (first positioning portion) 12e facing the protruding portion of the lever, which will be described later, and the reflecting means 10 are closed. There is formed a second recess 12f (third positioning portion) facing a protruding portion of the lever which will be described later. The reflecting means 10 is supported by the housing 40 so as to be rotatable by the shaft portion 12b.

第一の駆動手段２０は、ステッピングモータ２１と、このステッピングモータ２１の回動軸２１ａに固定された歯車２２と、この歯車２２に噛合する歯車２３と、を有している。歯車２３は、保持部材１２の軸部１２ｂと同軸状に配置され、保持部材１２の基部１２ａに固定されている。   The first drive means 20 includes a stepping motor 21, a gear 22 fixed to the rotating shaft 21 a of the stepping motor 21, and a gear 23 that meshes with the gear 22. The gear 23 is disposed coaxially with the shaft portion 12 b of the holding member 12 and is fixed to the base portion 12 a of the holding member 12.

フレーム部材３３は、バネ３４によって右向きに引っ張られており、当接部３３ａがカム３２に接触している。フレーム部材３３は、カム３２の回動にしたがってスライド移動する。   The frame member 33 is pulled rightward by the spring 34, and the contact portion 33 a is in contact with the cam 32. The frame member 33 slides as the cam 32 rotates.

レバー３５は、突出部（第二の位置決め部，第四の位置決め部）３５ａを有しており、後端部に設けられた軸部３５ｂによって回動可能な状態でフレーム部材３３に軸支されている。レバー３５は、先端部に設けられたバネ３６によって上向きに押し上げられており、突出部３５ａが保持部材１２の摺動部１２ｄに接触している。また、レバー部３５の先端部には回動部材３７の凹凸形状に対応した凹凸形状の噛合部３５ｃが形成されている。   The lever 35 has a projecting portion (second positioning portion, fourth positioning portion) 35a, and is pivotally supported by the frame member 33 in a state of being rotatable by a shaft portion 35b provided at the rear end portion. ing. The lever 35 is pushed upward by a spring 36 provided at the tip, and the protruding portion 35 a is in contact with the sliding portion 12 d of the holding member 12. Further, a concave and convex engaging portion 35 c corresponding to the concave and convex shape of the rotating member 37 is formed at the tip of the lever portion 35.

回動部材３７は、フレーム部材３３に軸支される軸部３７ａを備えるロータリーダンパ（緩衝部材）からなり、軸部３７ａによって回動可能な状態でフレーム部材３３に支持されるものである。また、回動部材３７は、レバー３５との当接個所が凹凸状に形成されており、レバー３５の先端部に形成される噛合部３５ｃと噛合している。   The rotating member 37 includes a rotary damper (buffer member) including a shaft portion 37a that is pivotally supported by the frame member 33, and is supported by the frame member 33 so as to be rotatable by the shaft portion 37a. Further, the rotating member 37 is formed in an uneven shape at the contact point with the lever 35, and meshes with a meshing portion 35 c formed at the tip of the lever 35.

次に、反射手段１０の開閉について詳述する。ヘッドアップディスプレイ装置を使用しない時には反射手段１０を閉じておき、使用する時に第一の駆動手段２０によって反射手段１０を所定の角度位置まで開くことができる。図２は反射手段１０が所定の角度位置まで開いた状態を示している。反射部材１０を開くときには、ステッピングモータ２１の回動軸２１ａが右に回り、ステッピングモータ２１の駆動力が歯車２２及び歯車２３を介して保持部材１２に伝達される。保持部材１２の摺動部１２ｄは、レバー３５の突出部３５ａに当接しながら左回りに回動し、反射手段１０が所定の角度位置まで起き上がったときに、保持部材１２の第一の凹部１２ｅがレバー３５の突出部３５ａに対向する。このとき、レバー３５の先端部がバネ３６によって上向きに押し上げられるため、レバー３５は軸部３５ｂを中心として右回りに回動して突出部３５ａが第一の凹部１２ｅに係合され、反射手段１０が位置決めされる。また、突出部３５ａの係合動作に際して、レバー３５の先端部は噛合部３５ｃと噛合する回動部材３７を左回りに回動させながら上方に移動することとなる。したがって、回動部材３７は、レバー３５の先端部に上方への移動に対向する一定の負荷が掛けることで突出部３５ａと第一の凹部１２ｅとの衝突に緩衝し、突出部３５ａの係合動作を減速させることで、突出部３５ａと第一の凹部１２ｅとの衝突を緩和して衝突音が発生することを抑制している。   Next, opening and closing of the reflecting means 10 will be described in detail. The reflective means 10 can be closed when the head-up display device is not used, and the reflective means 10 can be opened to a predetermined angular position by the first driving means 20 when used. FIG. 2 shows a state in which the reflecting means 10 is opened to a predetermined angular position. When the reflecting member 10 is opened, the rotation shaft 21 a of the stepping motor 21 rotates to the right, and the driving force of the stepping motor 21 is transmitted to the holding member 12 via the gear 22 and the gear 23. The sliding portion 12d of the holding member 12 rotates counterclockwise while coming into contact with the protruding portion 35a of the lever 35, and when the reflecting means 10 rises to a predetermined angular position, the first concave portion 12e of the holding member 12 is obtained. Faces the protrusion 35a of the lever 35. At this time, since the tip end of the lever 35 is pushed upward by the spring 36, the lever 35 rotates clockwise around the shaft portion 35b, and the projecting portion 35a is engaged with the first recess 12e. 10 is positioned. Further, during the engaging operation of the protruding portion 35a, the tip end portion of the lever 35 moves upward while rotating the rotating member 37 engaged with the engaging portion 35c counterclockwise. Therefore, the rotating member 37 buffers the collision between the projecting portion 35a and the first recessed portion 12e by applying a constant load on the distal end portion of the lever 35 to oppose the upward movement, and the engagement of the projecting portion 35a. By decelerating the operation, the collision between the protrusion 35a and the first recess 12e is alleviated and the occurrence of a collision sound is suppressed.

図３は、反射手段１０が閉じられた状態を示している。反射手段１０が閉じられるときには、ステッピングモータ２１の回動軸２１ａが左に回り、ステッピングモータ２１の駆動力が歯車２２及び歯車２３を介して保持部材１２に伝達される。保持部材１２の摺動部１２ｄは、レバー３５の突出部３５ａに当接しながら右回りに回動し、反射手段１０が閉じられたときに、保持部材１２の第二の凹部１２ｆがレバー３５の突出部３５ａに対向する。このとき、レバー３５の先端部がバネ３６によって上向きに押し上げられるため、レバー３５は軸部３５ｂを中心として右回りに回動して突出部３５ｄが第二の凹部１２ｆに係合され、反射手段１０が位置決めされる。また、突出部３５ａの係合動作に際して、レバー３５の先端部は噛合部３５ｃと噛合する回動部材３７を左回りに回動させながら上方に移動することとなる。したがって、回動部材３７は、レバー３５の先端部に上方への移動に対向する一定の負荷が掛けることで突出部３５ａと第二の凹部１２ｆとの衝突に緩衝し、突出部３５ａの係合動作を減速させることで、突出部３５ａと第二の凹部１２ｆとの衝突を緩和して衝突音が発生することを抑制している。なお、反射手段１０が閉じられた状態とは、反射手段１０の角度位置が、反射ミラー１１の表示面が利用者の視線から外れる程度の角度位置にある状態をいう。   FIG. 3 shows a state where the reflecting means 10 is closed. When the reflecting means 10 is closed, the rotation shaft 21a of the stepping motor 21 rotates to the left, and the driving force of the stepping motor 21 is transmitted to the holding member 12 via the gear 22 and the gear 23. The sliding portion 12d of the holding member 12 rotates clockwise while contacting the protruding portion 35a of the lever 35, and when the reflecting means 10 is closed, the second recess 12f of the holding member 12 is Opposite to the protrusion 35a. At this time, since the tip of the lever 35 is pushed upward by the spring 36, the lever 35 rotates clockwise around the shaft 35b, and the protrusion 35d is engaged with the second recess 12f, and the reflecting means. 10 is positioned. Further, during the engaging operation of the protruding portion 35a, the tip end portion of the lever 35 moves upward while rotating the rotating member 37 engaged with the engaging portion 35c counterclockwise. Therefore, the rotation member 37 buffers the tip 35 of the lever 35 against a collision between the protrusion 35a and the second recess 12f by applying a constant load that opposes the upward movement, and the engagement of the protrusion 35a. By decelerating the operation, the collision between the protrusion 35a and the second recess 12f is alleviated and the occurrence of a collision sound is suppressed. The state in which the reflecting means 10 is closed refers to a state in which the angular position of the reflecting means 10 is at an angular position such that the display surface of the reflecting mirror 11 deviates from the user's line of sight.

次に、反射手段１０の角度調整について詳述する。反射手段１０が所定の角度位置まで開いているときは、図示しない押ボタンスイッチを操作することによって第二の駆動手段３０を駆動させ、反射手段１０の角度Ａを調整することができる（図４参照）。第二の駆動手段３０は、ステッピングモータ３１の駆動力をカム３２，フレーム部材３３及びレバー３５を介して保持部材１２に伝達させて反射手段１０の角度位置を変位させるものである。すなわち、反射部材１０の角度Ａを大きくする場合には、ステッピングモータ３１の回動軸３１ａと共にカム３２が左に回り、フレーム部材３３及びレバー３５が左にスライド移動し、保持部材１２が左回りに回動する。   Next, the angle adjustment of the reflecting means 10 will be described in detail. When the reflecting means 10 is opened to a predetermined angular position, the second driving means 30 can be driven by operating a push button switch (not shown) to adjust the angle A of the reflecting means 10 (FIG. 4). reference). The second driving means 30 is configured to transmit the driving force of the stepping motor 31 to the holding member 12 via the cam 32, the frame member 33, and the lever 35 to displace the angular position of the reflecting means 10. That is, when the angle A of the reflecting member 10 is increased, the cam 32 rotates to the left together with the rotating shaft 31a of the stepping motor 31, the frame member 33 and the lever 35 slide to the left, and the holding member 12 rotates counterclockwise. To turn.

また、反射部材１０の角度Ａを小さくする場合には、ステッピングモータ３１の回動軸３１ａと共にカム３２が右に回り、フレーム部材３３及びレバー３５が右にスライド移動し、保持部材１２が右回りに回動する。   When the angle A of the reflecting member 10 is decreased, the cam 32 rotates to the right together with the rotation shaft 31a of the stepping motor 31, the frame member 33 and the lever 35 slide to the right, and the holding member 12 rotates clockwise. To turn.

かかるヘッドアップディスプレイ装置は、反射手段１０に備えられる第一の凹部１２ｅ及び第二の凹部１２ｆに対応する突出部３５ａを有し、反射手段１０が所定の角度位置で開いた状態で突出部３５ａを第一の凹部１２ｅに係合させ、また、反射手段１０が閉じた状態で突出部３５ａを第二の凹部１２ｆに係合させるレバー３５を備えてなるものである。また、反射手段１０は、レバー３５の突出部３５ａと当接した状態で回動する摺動部１２ｄを備え、摺動部１２ｄに第一の凹部１２ｅ及び第二の凹部１２ｆが形成されるものである。以上の構成により、反射手段１０を開いたときの位置決めを第一の凹部１２ｅと突出部３５ａとの係合によって行い、また、反射手段１０を閉じたときの位置決めを第二の凹部１２ｆと突出部３５ａとの係合によって行うことから、第一の駆動手段２０に備えられるステッピングモータ２１の動作環境や歯車２２，２３の噛合状態等に関わらず、反射手段１０を開いたときあるいは反射手段１０を閉じたときに、反射手段１０を精度よく所定の角度位置で停止させることが可能となる。   Such a head-up display device has a protrusion 35a corresponding to the first recess 12e and the second recess 12f provided in the reflection means 10, and the protrusion 35a is opened in a state where the reflection means 10 is opened at a predetermined angular position. Is engaged with the first recess 12e, and a lever 35 is provided for engaging the protrusion 35a with the second recess 12f with the reflecting means 10 closed. The reflecting means 10 includes a sliding portion 12d that rotates in contact with the protruding portion 35a of the lever 35. The sliding portion 12d is formed with a first concave portion 12e and a second concave portion 12f. It is. With the above configuration, the positioning when the reflecting means 10 is opened is performed by the engagement between the first recess 12e and the projecting portion 35a, and the positioning when the reflecting means 10 is closed is projected with the second recess 12f. Since it is performed by engaging with the portion 35a, when the reflecting means 10 is opened or the reflecting means 10 regardless of the operating environment of the stepping motor 21 provided in the first driving means 20 or the meshing state of the gears 22 and 23, etc. When is closed, the reflecting means 10 can be accurately stopped at a predetermined angular position.
