Utility Model Registration No. 2590842 (2nd page, FIG. 1) Japanese Utility Model Publication No. 6-844 (first page, FIG. 1)

特許文献１，２に記載のいずれの従来例も、スイッチの操作に当たっては、目視、触手によるスイッチ位置の確認が必要であり、運転操作の妨げになるばかりでなく、安全運転遂行上の問題となる懸念がある。   In any of the conventional examples described in Patent Documents 1 and 2, when the switch is operated, it is necessary to visually check the position of the switch with a tentacle, which not only hinders the driving operation but also a problem in performing safe driving. There are concerns.

そこで、本発明は、運転操作を妨げることなく、バイザーなどのベースに内蔵した照明装置のオン／オフを図ることができる自動車用車室内照明装置を提供することを目的とする。   SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle interior lighting device that can turn on / off a lighting device built in a base such as a visor without hindering driving operation.

本発明に係る自動車用車室内照明装置は、支軸をヒンジ部として開閉可能に取り付けられるベースと、前記ベースの表面側から光を照射する第１の光源と、前記ベースの裏面側から光を照射する第２の光源と、前記ベースに内蔵した検知電極により前記ベースの表面側及び裏面側の静電容量の変化を検出する静電容量センサと、前記ベースの開閉状態を検出するベース開閉検出手段とを備え、前記静電容量センサの検出結果と前記開閉検出手段の検出結果とに基づき、前記第１及び第２の光源を選択的にオン／オフ制御することを特徴とする。A vehicle interior lighting device according to the present invention includes a base that can be opened and closed with a support shaft as a hinge portion, a first light source that emits light from the front surface side of the base, and light from the back surface side of the base. A second light source to be irradiated; a capacitance sensor for detecting a change in capacitance on the front surface side and the back surface side of the base by a detection electrode built in the base; and a base open / close detection for detecting an open / closed state of the base Means for selectively on / off controlling the first and second light sources based on the detection result of the capacitance sensor and the detection result of the open / close detection means.
また、上記発明において、前記ベースが開状態の場合は、前記静電容量センサの検出結果に応じて前記第２の光源をオン／オフ制御し、前記ベースが閉状態の場合は、前記静電容量センサの検出結果に応じて前記第１の光源をオン／オフ制御することを特徴とする。  In the above invention, when the base is open, the second light source is turned on / off according to the detection result of the capacitance sensor, and when the base is closed, the electrostatic The first light source is on / off controlled in accordance with a detection result of a capacitance sensor.
さらに、上記発明において、前記ベース開閉検出手段は、前記ベースのヒンジ部に設けられた機械的なスイッチ、または前記ベースの内側に設置され明暗を検知する光センサ、または前記ベースの傾きを検出する傾きセンサによって、前記ベースの開閉状態を検出することを特徴とする。  Further, in the above invention, the base opening / closing detection means detects a mechanical switch provided in a hinge portion of the base, an optical sensor installed inside the base to detect light or dark, or an inclination of the base. An opening / closing state of the base is detected by an inclination sensor.

本発明によれば、天井側からウィンド側に反転するバイザー本体をベースとしたとき、このベースの片面又は両面に光源を設け、この光源のオン／オフをバイザー本体に内蔵した静電容量センサで行うようにしたので、運転者が運転中であってもバイザー本体に触れるだけで、すなわち運転者のアバウトな操作で光源のオン／オフ操作を行うことができ、安全運転を妨げない。   According to the present invention, when a visor body that is inverted from the ceiling side to the window side is used as a base, a light source is provided on one or both sides of the base, and the on / off of the light source is a capacitance sensor built in the visor body. Thus, even when the driver is driving, the light source can be turned on / off only by touching the visor body, that is, the driver's about operation, and safe driving is not hindered.

以下に、本発明の実施形態について図面を参照にして説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は、ベース（バイザー本体）１を天井側からウィンド側に反転した状態の図であり、支軸２にベース１を反転可能（開閉可能）に取り付けてあり、この支軸２をヒンジ部としてベース１を反転させることができる。このベース１の裏面側にバニティミラー３を取り付けてあり、このバニティミラー３の両側に電球あるいはＬＥＤを用いた光源４を設けてある。また、図２は、ベース１の表面側を示し、すなわち天井側にベース１を格納した状態である。ベース１の表面側にはマップランプ５を取り付けてある。   FIG. 1 is a view of a state in which a base (visor main body) 1 is inverted from the ceiling side to the window side, and the base 1 is attached to a support shaft 2 so as to be able to be inverted (openable and closable). The base 1 can be inverted. A vanity mirror 3 is attached to the back side of the base 1, and a light source 4 using a light bulb or LED is provided on both sides of the vanity mirror 3. Moreover, FIG. 2 shows the surface side of the base 1, that is, a state in which the base 1 is stored on the ceiling side. A map lamp 5 is attached to the surface side of the base 1.

図３は、フレキシブル配線板１０上に静電容量センサ（検知電極）６と照明回路（制御回路）７を統合して配設し、このフレキシブル配線板１０のマップランプ５用の光源５Ａの近傍を折曲個所Ａで折り曲げてベース１に内蔵するようにしたものである。この静電容量センサ６の個所に触れると光源４、５Ａがオンするようになっている。この例では、その構造上、表面側、裏面側ともに静電容量の変化（人体や指などの導電物の接近）を検出することができるため、自動車用バイザーのような薄いものに内蔵することで、対象物の表面側、裏面側の双方で静電容量の変化を検出することが可能となる。   FIG. 3 shows an arrangement in which a capacitance sensor (detection electrode) 6 and an illumination circuit (control circuit) 7 are integrated on a flexible wiring board 10 and in the vicinity of the light source 5A for the map lamp 5 of the flexible wiring board 10. Is bent at a bent portion A and incorporated in the base 1. When the location of the electrostatic capacitance sensor 6 is touched, the light sources 4 and 5A are turned on. In this example, because of the structure, it is possible to detect changes in capacitance on both the front and back sides (approach of conductive materials such as human bodies and fingers), so it should be built into a thin object such as an automobile visor. Thus, it is possible to detect a change in capacitance on both the front side and the back side of the object.

本発明の上記実施形態では、ベース１の展開時（反転時）はバニティミラー照明のオン／オフを、またベース１の格納時にはマップランプ５のオン／オフを、ベース１の内部に内蔵した静電容量センサ６を用いて行っている。このときに問題となるのは、ベース１の表裏双方の照明回路７を同時に点灯すると、特にベース１の展開時にマップランプ５の照明が点灯することで、対向車を幻惑する危険性があるため、ベース１の展開／格納状態に従って点灯するべき照明を選択する必要がある。一方で、ベース１の展開／格納状態を検出することによって、静電容量センサ６でオン／オフすべき照明は排他的に選択可能であるため、比較的高価な静電容量センサ６はひとつだけで、２つの照明回路をオン／オフすることが可能となる。そのための、フローチャートを図４に示す。図４では、ベース（バイザー本体）１の開閉の検出には、ベース（バイザー本体）１のヒンジ部に機械的なスイッチ（マイクロスイッチなど）を用いて開閉を検出する方式や、光センサをベース（バイザー本体）１の内側（バニティミラー側）に設置して明暗を検出する方式、あるいは傾きセンサ（加速度センサ）を用いてベース（バイザー本体）１の傾きを検出する方式などが考えられる。図４のフローチャートの実現に関しては、ＣＰＵなどを利用したデジタル回路でも実現可能であるし、フリップフロップＩＣなどのロジックＩＣを利用した方式でも実現が可能である。   In the above embodiment of the present invention, when the base 1 is deployed (inverted), vanity mirror illumination is turned on / off, and when the base 1 is retracted, the map lamp 5 is turned on / off inside the base 1. This is performed using the capacitance sensor 6. The problem at this time is that if both the front and back lighting circuits 7 of the base 1 are turned on at the same time, the illumination of the map lamp 5 is turned on, particularly when the base 1 is deployed, and there is a risk of dazzling oncoming vehicles. It is necessary to select the lighting to be turned on according to the deployed / retracted state of the base 1. On the other hand, since the illumination to be turned on / off by the capacitance sensor 6 can be exclusively selected by detecting the deployed / retracted state of the base 1, there is only one relatively expensive capacitance sensor 6. Thus, the two lighting circuits can be turned on / off. A flowchart for this purpose is shown in FIG. In FIG. 4, the detection of opening / closing of the base (visor main body) 1 is based on a method of detecting opening / closing using a mechanical switch (such as a micro switch) on the hinge portion of the base (visor main body) 1 or an optical sensor as a base. A method of detecting the light and darkness by installing inside the (visor main body) 1 (vanity mirror side) or a method of detecting the inclination of the base (visor main body) 1 using an inclination sensor (acceleration sensor) is conceivable. 4 can be realized by a digital circuit using a CPU or the like, or by a method using a logic IC such as a flip-flop IC.

本発明の適用事例としては、自動車用バイザーの表裏両面の照明用途以外にも、グローブボックス内部照明と助手席足元照明の兼用（グローブボックスの蓋をベースとする）、コンソールボックス上のトレイ照明とボックス内部の照明の兼用（コンソールボックスの開閉蓋をベースとする）、その他車室内の蓋付きのボックス類に応用が可能である。   As an application example of the present invention, in addition to the illumination use on both the front and back sides of the visor for automobiles, the glove box internal illumination and the front passenger's foot illumination can be combined (based on the lid of the glove box), the tray illumination on the console box, It can also be used for lighting inside the box (based on the opening / closing lid of the console box) and other boxes with lids in the vehicle compartment.
