Description

ヘッドアップディスプレイ装置Head-up display device
　本発明は、本体部に対して出没可能なコンバイナを有するヘッドアップディスプレイ装置に関する。 The present invention relates to a head-up display device having a combiner capable of appearing and retracting with respect to a main body.
　例えば、車両の乗員にナビゲーション情報を提供するために、ヘッドアップディスプレイ装置が用いられる。ヘッドアップディスプレイ装置として、コンバイナが本体部に対して出没可能に設けられ、このコンバイナに情報を投射させるタイプのものが知られている。このようなコンバイナを有するヘッドアップディスプレイ装置として、特許文献１に開示される技術がある。 For example, a head-up display device is used to provide navigation information to vehicle occupants. As a head-up display device, there is known a type in which a combiner is provided so as to be able to appear in and out of a main body, and information is projected onto the combiner. As a head-up display device having such a combiner, there is a technique disclosed in Patent Document 1.
　特許文献１の図１、及び、図４に示されるような、ヘッドアップディスプレイ装置は、本体部に取り付けられたウォームホイール機構と、このウォームホイール機構によって駆動されるリンク機構と、このリンク機構に接続され本体部に対して昇降可能に設けられたコンバイナと、を有する。 A head-up display device as shown in FIG. 1 and FIG. 4 of Patent Document 1 includes a worm wheel mechanism attached to a main body, a link mechanism driven by the worm wheel mechanism, and a link mechanism. And a combiner that is connected and provided to be movable up and down with respect to the main body.
　ウォームホイール機構は、本体部に取り付けられたモータと、このモータのモータ軸に設けられたウォームと、このウォームに噛み合いリンク機構に接続されるホイールと、からなる。 The worm wheel mechanism includes a motor attached to the main body, a worm provided on the motor shaft of the motor, and a wheel meshing with the worm and connected to the link mechanism.
　このようなヘッドアップディスプレイ装置は、モータを駆動させることにより、モータ軸、及び、ウォームを回転させる。これにより、ウォームに噛み合うホイールが回転されて、リンク機構が駆動される。リンク機構が駆動されることにより、コンバイナが昇降する。 Such a head-up display device rotates a motor shaft and a worm by driving a motor. Thereby, the wheel meshing with the worm is rotated, and the link mechanism is driven. When the link mechanism is driven, the combiner moves up and down.
　コンバイナを上昇させると、コンバイナは本体部の外部に突出し、乗員に視認可能な状態となる。コンバイナに情報を投射させることにより、乗員は、情報を得ることができる。一方、停車時等においては、コンバイナを降下させる。これにより、コンバイナが本体部内に収納される。 When the combiner is raised, the combiner protrudes outside the main body and is visible to the occupant. By causing the combiner to project information, the occupant can obtain information. On the other hand, when the vehicle stops, the combiner is lowered. Thereby, a combiner is accommodated in a main-body part.
　例えば、コンバイナの使用時には、コンバイナを本体部から突出させた状態に保つ必要がある。このため、ウォームホイール機構は、セルフロックの機能を有していることが一般的である。即ち、ウォームとホイールの噛み合いによって、コンバイナを突出させた状態に保つことができる。このため、突出している状態のコンバイナを押し下げようとしても、ウォームによってホイールの回転が防止され、コンバイナを押し下げることができない。 For example, when using a combiner, it is necessary to keep the combiner protruding from the main body. For this reason, the worm wheel mechanism generally has a self-locking function. That is, the combiner can be kept protruding by the meshing of the worm and the wheel. For this reason, even if it is going to push down the combiner of the state which protrudes, rotation of a wheel is prevented by a worm and a combiner cannot be pushed down.
　ところで、ヘッドアップディスプレイ装置のメンテナンス時等において、モータへ電気を供給できない状況が考えられる。このような場合には、手動でコンバイナを動かすことができれば好ましい。取り扱い性に優れたヘッドアップディスプレイ装置の提供が望まれる。 By the way, there may be a situation where electricity cannot be supplied to the motor during maintenance of the head-up display device. In such a case, it is preferable if the combiner can be moved manually. It is desired to provide a head-up display device with excellent handling properties.

　本発明は、取り扱い性に優れたヘッドアップディスプレイ装置の提供を課題とする。 An object of the present invention is to provide a head-up display device having excellent handling properties.
　請求項１による発明によれば、本体部に設けられた駆動機構と、この駆動機構によって駆動され前記本体部に対して出没可能なコンバイナと、を有するヘッドアップディスプレイ装置において、
　前記駆動機構は、モータと、このモータのモータ軸に設けられたウォームと、このウォームに噛み合うホイールと、を有し、
　前記本体部は、前記モータを取り付けるためのモータ取付部を有し、
　前記モータは、前記モータ取付部に締結部材を介して取り付けられ、
　前記モータ取付部は、前記モータ軸が貫通するモータ軸貫通孔、及び、前記締結部材が貫通する締結部材貫通孔、を有し、
　前記モータ軸貫通孔は、前記ウォームの前記ホイールへの噛み合いを解除するために、前記モータ軸の変位を許容するモータ軸逃げ部を有し、
　前記締結部材貫通孔は、前記モータ軸の変位を許容するよう、前記締結部材の変位を許容する締結部材逃げ部を有していることを特徴とするヘッドアップディスプレイ装置が提供される。 According to the invention of claim 1, in a head-up display device having a drive mechanism provided in a main body portion and a combiner driven by the drive mechanism and capable of appearing and retracting with respect to the main body portion,
The drive mechanism has a motor, a worm provided on the motor shaft of the motor, and a wheel meshing with the worm,
The main body has a motor mounting portion for mounting the motor,
The motor is attached to the motor attachment portion via a fastening member,
The motor mounting portion has a motor shaft through hole through which the motor shaft passes, and a fastening member through hole through which the fastening member passes,
The motor shaft through-hole has a motor shaft escape portion that allows displacement of the motor shaft in order to release the meshing of the worm with the wheel.
The head-up display device is provided in which the fastening member through hole has a fastening member escape portion that allows the displacement of the fastening member so as to allow the displacement of the motor shaft.
　請求項１に係る発明では、モータ軸貫通孔は、ウォームのホイールへの噛み合いを解除するために、モータ軸の変位を許容するモータ軸逃げ部を有している。加えて、締結部材貫通孔は、モータ軸の変位を許容するよう、締結部材の変位を許容する締結部材逃げ部を有している。これにより、締結部材を緩めることにより、モータをモータ軸逃げ部に逃がすと共に、締結部材を締結部材逃げ部に逃がすことができる。これにより、ウォームのホイールへの噛み合いを解除することができる。ウォームとホイールとの噛み合い状態を解除することにより、コンバイナを手動で動かすことができる。取り扱い性に優れたヘッドアップディスプレイ装置ということができる。 In the invention according to claim 1, the motor shaft through-hole has a motor shaft escape portion that allows displacement of the motor shaft in order to release the engagement of the worm with the wheel. In addition, the fastening member through hole has a fastening member relief portion that allows the displacement of the fastening member so as to allow the displacement of the motor shaft. Thereby, by loosening a fastening member, while letting a motor escape to a motor shaft escape part, a fastening member can escape to a fastening member escape part. As a result, the meshing of the worm with the wheel can be released. By releasing the meshing state between the worm and the wheel, the combiner can be moved manually. It can be said that the head-up display device is excellent in handleability.

And a return spring 57 for urging 51 toward the rear. The link mechanism 50 is provided on the right side surface of the main body 11 with substantially the same configuration. Description of the link mechanism provided on the right side surface portion is omitted.
　図４、及び、図５を参照する。モータ取付部６０には、ウォーム２２の直径よりも大きい円形状のモータ軸貫通孔６１と、このモータ軸貫通孔６１を囲う長円形状の締結部材貫通孔６２と、モータ軸貫通孔６１に対向した部位に位置する長円形状のモータ軸先端部貫通孔６３と、が形成されている。 Refer to FIG. 4 and FIG. The motor mounting portion 60 has a circular motor shaft through hole 61 larger than the diameter of the worm 22, an oblong fastening member through hole 62 surrounding the motor shaft through hole 61, and the motor shaft through hole 61. An oblong motor shaft tip portion through-hole 63 located at the above-mentioned part is formed.
　モータ軸貫通孔６１には、モータ軸２１ａが貫通している。モータ軸貫通孔６１は、モータ軸２１ａの直径に対して十分に大きく形成されている。このため、モータ軸２１ａを変位させることができる。即ち、モータ軸貫通孔６１は、モータ軸２１ａの変位を許容するモータ軸逃げ部６１ａを有しているということができる。 The motor shaft 21a passes through the motor shaft through hole 61. The motor shaft through hole 61 is formed sufficiently large with respect to the diameter of the motor shaft 21a. For this reason, the motor shaft 21a can be displaced. That is, it can be said that the motor shaft through hole 61 has the motor shaft escape portion 61a that allows the displacement of the motor shaft 21a.
　締結部材貫通孔６２には、それぞれ、ボルト３１が貫通している。締結部材貫通孔６２の短手方向の幅Ｗ１は、ボルト３１の直径Ｄ１と略同じ大きさである。ここで、略同じ大きさとは、締結部材貫通孔６２の縁に沿ったボルト３１の移動を許容する程度に、締結部材貫通孔６２の短手方向の幅Ｗ１がボルト３１の直径Ｄ１よりも僅かに大きいことを言う。 The bolts 31 penetrate the fastening member through holes 62, respectively. The width W1 in the short direction of the fastening member through-hole 62 is substantially the same as the diameter D1 of the bolt 31. Here, the substantially same size means that the width W1 in the short direction of the fastening member through-hole 62 is slightly smaller than the diameter D1 of the bolt 31 to the extent that the movement of the bolt 31 along the edge of the fastening member through-hole 62 is allowed. Say great to you.
　ボルト３１は、締結部材貫通孔６２に沿って移動可能である。即ち、締結部材貫通孔６２は、ボルト３１の変位を許容する締結部材逃げ部６２ａを有している。組み付け状態を基準として、ボルト３１は、締結部材貫通孔６２の端部に位置している。換言すれば、ウォーム２２と、ホイール２３と、が噛み合っているとき、ボルト３１は、締結部材貫通孔６２の端部に位置している。 The bolt 31 is movable along the fastening member through hole 62. That is, the fastening member through-hole 62 has a fastening member escape portion 62 a that allows displacement of the bolt 31. Based on the assembled state, the bolt 31 is located at the end of the fastening member through-hole 62. In other words, when the worm 22 and the wheel 23 are engaged with each other, the bolt 31 is located at the end of the fastening member through hole 62.
　モータ軸先端部貫通孔６３の縁において、モータ軸２１ａの先端部が支持されている。モータ軸先端部貫通孔６３の形状についても、締結部材貫通孔６２の形状と同様である。即ち、モータ軸先端部貫通孔６３には、モータ軸２１ａの先端部が貫通している。モータ軸先端部貫通孔６３の短手方向の幅は、モータ軸２１ａの直径と略同じ大きさである。ここで、略同じ大きさとは、モータ軸先端部貫通孔６３の縁に沿ったモータ軸２１ａの移動を許容する程度に、モータ軸先端部貫通孔６３の短手方向の幅がモータ軸２１ａの直径よりも僅かに大きいことを言う。 The tip of the motor shaft 21 a is supported at the edge of the motor shaft tip through hole 63. The shape of the motor shaft tip through hole 63 is also the same as the shape of the fastening member through hole 62. That is, the front end portion of the motor shaft 21 a passes through the motor shaft front end portion through hole 63. The width of the motor shaft tip end through hole 63 in the short direction is substantially the same as the diameter of the motor shaft 21a. Here, the substantially same size means that the width of the motor shaft tip through-hole 63 in the short direction of the motor shaft 21a is such that the movement of the motor shaft 21a along the edge of the motor shaft tip through-hole 63 is allowed. Say that it is slightly larger than the diameter.
　モータ軸２１ａは、モータ軸先端部貫通孔６３に沿って移動可能である。即ち、モータ軸先端部貫通孔６３は、モータ軸２１ａの先端部の変位を許容するモータ軸先端部逃げ部６３ａを有している。組み付け状態を基準として、モータ軸２１ａは、モータ軸先端部貫通孔６３の端部に位置している。換言すれば、ウォーム２２と、ホイール２３と、が噛み合っているとき、モータ軸２１ａの先端部は、モータ軸先端部貫通孔６３の端部に位置している。 The motor shaft 21a is movable along the motor shaft tip end through hole 63. That is, the motor shaft tip portion through-hole 63 has a motor shaft tip portion relief portion 63a that allows displacement of the tip portion of the motor shaft 21a. The motor shaft 21 a is located at the end of the motor shaft tip end through hole 63 with the assembled state as a reference. In other words, when the worm 22 and the wheel 23 are engaged with each other, the tip of the motor shaft 21 a is located at the end of the motor shaft tip through hole 63.
　図１に示された、本体部１１の内部にコンバイナ１４が収納されている収納状態から、図２に示された、本体部１１の上方にコンバイナ１４が突出した突出状態までの作用について説明する。 The operation from the housed state in which the combiner 14 is housed in the main body 11 shown in FIG. 1 to the projecting state in which the combiner 14 protrudes above the body 11 shown in FIG. 2 will be described. .
　例えば、車両のイグニッションスイッチがオフにされた状態では、コンバイナ１４は、本体部１１の内部に収納されている。このとき、イグニッションスイッチがオンにされると、コンバイナ１４は、本体部１１の上方に向かって進出する。 For example, in a state where the ignition switch of the vehicle is turned off, the combiner 14 is housed inside the main body 11. At this time, when the ignition switch is turned on, the combiner 14 advances toward the upper side of the main body 11.
　図３を参照する。イグニッションスイッチがオンにされることにより、モータ２１が駆動され、モータ軸２１ａ、及び、ウォーム２２が回転する。これにより、ウォーム２２に噛み合うホイール２３と、このホイール２３の回転軸ＣＬ２上に設けられた駆動ギヤ２４と、が回転する。これにより、駆動ギヤ２４に噛み合っている従動ギヤ２５と、この従動ギヤ２５の回転軸ＣＬ３上に設けられたピニオンギヤ２６と、が回転する。ピニオンギヤ２６が回転すると、ピニオンギヤ２６に噛み合うラック部４１ａを介して押圧板４０が前進する。押圧板４０が前進することにより、当接部４３，４３を介して、第１のアーム５２（図１参照）が前方に向かって押される。 Refer to FIG. When the ignition switch is turned on, the motor 21 is driven, and the motor shaft 21a and the worm 22 rotate. As a result, the wheel 23 meshing with the worm 22 and the drive gear 24 provided on the rotation axis CL2 of the wheel 23 rotate. As a result, the driven gear 25 meshed with the drive gear 24 and the pinion gear 26 provided on the rotation shaft CL3 of the driven gear 25 rotate. When the pinion gear 26 rotates, the pressing plate 40 moves forward via the rack portion 41a that meshes with the pinion gear 26. As the pressing plate 40 moves forward, the first arm 52 (see FIG. 1) is pushed forward via the contact portions 43 and 43.
　図１を参照する。イグニッションスイッチをオンにすることにより、第１のアーム５２は、戻しばね５７の付勢力に抗して前方に向かって移動する。第１のアーム５２は、端部に設けられた第１のピン５１がガイド部１１ａに案内されながら前進する。第１のアーム５２が前進するのに合わせて、第２のアーム５５がスイングする。第２のアーム５５は、第３のピン５４を中心にスイングする。コンバイナ１４は、第４のピン５６のスイングの軌道に沿って本体部１１の上方に進出する。 Refer to FIG. By turning on the ignition switch, the first arm 52 moves forward against the biasing force of the return spring 57. The first arm 52 moves forward while the first pin 51 provided at the end is guided by the guide portion 11a. As the first arm 52 moves forward, the second arm 55 swings. The second arm 55 swings around the third pin 54. The combiner 14 advances above the main body 11 along the swing path of the fourth pin 56.
　図２を参照する。コンバイナ１４が本体部１１の上方に突出したら、モータ２１への通電を終了する。モータ２１への通電を終了した場合であっても、ウォーム２２のセルフロック機能によって、コンバイナ１４の突出状態が保たれる。ウォーム２２は、戻しばね５７の付勢力に抗してコンバイナ１４を突出状態に保つ。 Refer to FIG. When the combiner 14 protrudes above the main body 11, energization of the motor 21 is terminated. Even when energization of the motor 21 is finished, the protruding state of the combiner 14 is maintained by the self-locking function of the worm 22. The worm 22 keeps the combiner 14 in a protruding state against the urging force of the return spring 57.
　イグニッションスイッチがオフにされると、コンバイナ１４は、突出位置から収納位置まで変位される。モータ２１は、収納状態から突出状態のときとは逆方向に回転する。これにより、コンバイナ１４は、突出位置から収納位置まで変位される。 When the ignition switch is turned off, the combiner 14 is displaced from the protruding position to the storage position. The motor 21 rotates in the opposite direction to the protruding state from the housed state. Thereby, the combiner 14 is displaced from the protruding position to the storage position.
　図４、及び、図５を参照する。ヘッドアップディスプレイ装置１０のメンテナンス時等において、モータ２１へ電気を供給できない状況が考えられる。このような場合には、手動でコンバイナ１４（図２参照）を動かすことができれば好ましい。本発明によるヘッドアップディスプレイ装置１０では、ウォーム２２とホイール２３との噛み合いを容易に解除することができる構成を採用することにより、コンバイナ１４を手動で変位させることができるようにした。 Refer to FIG. 4 and FIG. There may be a situation where electricity cannot be supplied to the motor 21 during maintenance of the head-up display device 10 or the like. In such a case, it is preferable if the combiner 14 (see FIG. 2) can be moved manually. In the head-up display device 10 according to the present invention, the combiner 14 can be manually displaced by adopting a configuration in which the engagement between the worm 22 and the wheel 23 can be easily released.
　より具体的には、ナット３２を緩めた後に、モータ２１をホイール２３から離間する方向（図面右）に移動させる。モータ２１、ウォーム２２、ステー２８、ボルト３１、及び、ナット３２は、一体的に移動する。モータ２１は、締結部材貫通孔６２やモータ軸先端部貫通孔６３の形成されている方向に沿って移動される。締結部材貫通孔６２の短手方向の幅Ｗ１は、ボルト３１の直径よりも僅かに大きい。このため、モータ２１を移動させる際には、締結部材貫通孔６２がモータ２１の移動方向のガイドとなる。モータ軸先端部貫通孔６３についても同様、モータ２１の移動方向のガイドとなる。 More specifically, after loosening the nut 32, the motor 21 is moved in a direction away from the wheel 23 (right of the drawing). The motor 21, the worm 22, the stay 28, the bolt 31, and the nut 32 move integrally. The motor 21 is moved along the direction in which the fastening member through hole 62 and the motor shaft tip portion through hole 63 are formed. The width W <b> 1 in the short direction of the fastening member through hole 62 is slightly larger than the diameter of the bolt 31. For this reason, when the motor 21 is moved, the fastening member through hole 62 serves as a guide in the moving direction of the motor 21. Similarly, the motor shaft tip end through hole 63 serves as a guide in the moving direction of the motor 21.
　図６、及び、図７を参照する。モータ軸２１ａ（先端部を含む）、及び、ボルト３１をそれぞれの逃げ部６１ａ，６２ａ，６３ａまで移動させることにより、ウォーム２２と、ホイール２３との噛み合いが解除される。 Refer to FIG. 6 and FIG. By moving the motor shaft 21a (including the tip portion) and the bolt 31 to the respective relief portions 61a, 62a, 63a, the meshing between the worm 22 and the wheel 23 is released.
　即ち、モータ軸貫通孔６１は、ウォーム２２のホイール２３への噛み合いを解除するために、モータ軸２１ａの変位を許容するモータ軸逃げ部６１ａを有している、ということができる。締結部材貫通孔６２、及び、モータ軸先端部貫通孔６３についても同様である。締結部材貫通孔６２は、モータ軸２１ａの変位を許容するよう、ボルト３１の変位を許容する締結部材逃げ部６２ａを有している。モータ軸先端部貫通孔６３は、ウォーム２２のホイール２３への噛み合いを解除するために、モータ軸２１ａの先端部の変位を許容するモータ軸先端部逃げ部６３ａを有している。 That is, it can be said that the motor shaft through hole 61 has a motor shaft escape portion 61a that allows displacement of the motor shaft 21a in order to release the engagement of the worm 22 with the wheel 23. The same applies to the fastening member through hole 62 and the motor shaft tip portion through hole 63. The fastening member through-hole 62 has a fastening member escape portion 62a that allows displacement of the bolt 31 so as to allow displacement of the motor shaft 21a. The motor shaft tip portion through-hole 63 has a motor shaft tip portion relief portion 63a that allows displacement of the tip portion of the motor shaft 21a in order to release the engagement of the worm 22 with the wheel 23.
　ウォーム２２と、ホイール２３と、の噛み合いが解除されることにより、ウォーム２２のセルフロック機能も解除される。このため、コンバイナ１４（図２参照）を手動で変位させることができる。コンバイナ１４を手動で変位させた際には、ホイール２３が空回りする。 When the meshing between the worm 22 and the wheel 23 is released, the self-lock function of the worm 22 is also released. For this reason, the combiner 14 (refer FIG. 2) can be displaced manually. When the combiner 14 is manually displaced, the wheel 23 rotates idle.
　本発明のヘッドアップディスプレイ装置１０は、以下の効果を奏する。 The head-up display device 10 of the present invention has the following effects.
　図３を参照する。モータ軸貫通孔６１は、ウォーム２２のホイール２３への噛み合いを解除するために、モータ軸２１ａの変位を許容するモータ軸逃げ部６１ａを有している。加えて、締結部材貫通孔６２は、モータ軸２１ａの変位を許容するよう、ボルト３１の変位を許容する締結部材逃げ部６２ａを有している。 Refer to FIG. The motor shaft through hole 61 has a motor shaft escape portion 61a that allows displacement of the motor shaft 21a in order to release the engagement of the worm 22 with the wheel 23. In addition, the fastening member through hole 62 has a fastening member escape portion 62a that allows displacement of the bolt 31 so as to allow displacement of the motor shaft 21a.
　図６を併せて参照する。これにより、ボルト３１を緩めることにより、モータ２１をモータ軸逃げ部６１ａに逃がすと共に、ボルト３１を締結部材逃げ部６２ａに逃がすことができる。これにより、ウォーム２２のホイール２３への噛み合いを解除することができる。ウォーム２２とホイール２３との噛み合い状態を解除することにより、コンバイナ１４（図５参照）を手動で動かすことができる。取り扱い性に優れたヘッドアップディスプレイ装置１０ということができる。 Referring also to FIG. Thereby, by loosening the bolt 31, the motor 21 can escape to the motor shaft escape portion 61a and the bolt 31 can escape to the fastening member escape portion 62a. Thereby, the meshing of the worm 22 with the wheel 23 can be released. By releasing the meshed state between the worm 22 and the wheel 23, the combiner 14 (see FIG. 5) can be moved manually. It can be said that the head-up display device 10 is excellent in handleability.
　図５を参照する。締結部材貫通孔６２は、長円形状を呈する。締結部材貫通孔６２の短手方向の幅Ｗ１は、ボルト３１（締結部材３１）の変位を許容する程度に、ボルト３１の直径Ｄ１よりも僅かに大きい。ボルト３１は、長円形状の端部に位置する。ボルト３１の配置される位置を容易に認識することができると共に、長円形状の孔の縁がストッパとなるため、ヘッドアップディスプレイ装置１０の組み立て作業が容易になる。モータ軸先端部貫通孔６３についても同様である。 Refer to FIG. The fastening member through hole 62 has an oval shape. The width W1 in the short direction of the fastening member through-hole 62 is slightly larger than the diameter D1 of the bolt 31 to the extent that the displacement of the bolt 31 (fastening member 31) is allowed. The bolt 31 is located at the end of the oval shape. The position where the bolt 31 is disposed can be easily recognized, and the edge of the oval hole serves as a stopper, so that the assembly work of the head-up display device 10 is facilitated. The same applies to the motor shaft tip end through hole 63.
