Description

本発明は、例えば車両のヘッドライト、ワイパー、方向指示器等を操作するためのレバーコンビネーションスイッチなどとして用いられる多方向操作装置に関するものである。   The present invention relates to a multidirectional operation device used as, for example, a lever combination switch for operating a vehicle headlight, a wiper, a direction indicator, and the like.

この種の多方向操作装置として、例えば特許文献１〜６に示されるように、ノブが回動操作されたり、或いはレバーが傾動操作されたりすることに伴って、摺動式の有接点スイッチを通じて電流経路が切り替えられるとともに、それにより操作態様に応じたライト、ターン、ワイパーの動作が実現されるレバーコンビネーションスイッチが提案されている。
特開２０００−１１８１５号公報 特開平１１−３２９１６２号公報 特開２０００−２３１８４１号公報 特開２０００−２０８００３号公報 特開２０００−１８２４５７号公報 特開２００３−２７６５７３号公報 As this type of multi-directional operation device, for example, as shown in Patent Documents 1 to 6, through a sliding contact switch as a knob is rotated or a lever is tilted. A lever combination switch has been proposed in which the current path is switched and the operation of the light, turn, and wiper according to the operation mode is realized.

しかしながら、有接点スイッチが用いられる従来のレバーコンビネーションスイッチでは、接点が経年劣化に起因して摩耗してしまったり、スプレー等に混ざっている揮発したシリコーン分子等が接点部分に付着して接点に絶縁膜が形成されたりすると、操作態様に応じて接触した接点部分に電流が流れなくなって接点不良を生じてしまうおそれがある。このため、操作検出の信頼性の観点ではなお改善の余地が残されている。   However, in the conventional lever combination switch using a contact switch, the contact is worn due to deterioration over time, or volatilized silicone molecules mixed in the spray adheres to the contact part and insulates the contact. When a film is formed, there is a risk that current will not flow through the contact portion that is in contact with the operation mode, resulting in contact failure. For this reason, there is still room for improvement from the viewpoint of reliability of operation detection.

本発明は、このような問題点に着目してなされたものであって、その目的は、操作を高い信頼性で検出することができる多方向操作装置を提供することにある。   The present invention has been made paying attention to such problems, and an object of the present invention is to provide a multidirectional operation device capable of detecting an operation with high reliability.

上記の課題を解決するために、請求項１に記載の発明では、傾動方向を含む多方向に操作可能な操作軸と、その操作軸に設けられた被検出部と、該操作軸の操作に応じて移動する前記被検出部の近接または接触を個別に検知する無接点式検出部とを備え、該無接点式検出部は、前記操作軸の傾動方向において前記被検出部と対向配置されて該操作軸の傾動操作を検出する傾動検出部位と、前記操作軸の回転方向において前記被検出部と対向配置されて該操作軸の回転操作を検出する回転検出部位と、前記操作軸の軸方向において前記被検出部と対向配置されて該操作軸の軸方向への移動操作を検出する軸移動検出部位とを備えることを要旨とする。   In order to solve the above-described problems, in the invention described in claim 1, an operation shaft that can be operated in multiple directions including a tilting direction, a detected portion provided on the operation shaft, and an operation of the operation shaft. And a contactless detection unit that individually detects the proximity or contact of the detected part that moves in response to the contacted part, and the contactless detection part is disposed to face the detected part in the tilting direction of the operation shaft. A tilt detection part that detects a tilting operation of the operation shaft, a rotation detection part that is disposed opposite to the detected portion in the rotation direction of the operation shaft and detects a rotation operation of the operation shaft, and an axial direction of the operation shaft And a shaft movement detection part that is arranged to face the detected part and detects a movement operation of the operation shaft in the axial direction.

上記構成によると、操作軸の多方向への操作は無接点式検出部によって検出可能となるため、接点不良を生じてしまうことなく確実に該操作を検出可能となる。また、傾動検出部位によって操作軸の傾動方向が検出され、回転検出部位によって操作軸の回転操作が検出され、軸移動検出部位によって操作軸の軸方向への移動が検出される。すなわち、操作軸の種々の方向への操作が検出可能となる。よって、高い信頼性を有する多機能操作装置として適用することができる。   According to the above configuration, the operation of the operation shaft in multiple directions can be detected by the non-contact detection unit, so that the operation can be reliably detected without causing a contact failure. In addition, the tilt direction of the operation shaft is detected by the tilt detection part, the rotation operation of the operation shaft is detected by the rotation detection part, and the movement of the operation axis in the axial direction is detected by the axis movement detection part. That is, operations in various directions of the operation shaft can be detected. Therefore, it can be applied as a multi-function operating device having high reliability.

請求項２に記載の発明では、請求項１に記載の多方向操作装置において、前記被検出部は、前記操作軸の軸側面に設けられた複数の突部によって構成され、前記無接点式検出部は、前記操作軸の周辺において各突部と対応する箇所にそれぞれ離間して設けられるとともに、前記傾動検出部位は前記各突部と対向配置され、前記回転検出部位はその傾動検出部位から前記操作軸の回転に伴う前記各突部の回転軌跡に干渉する位置まで延出され、前記軸移動検出部位は該傾動検出部位から前記各突部の軸移動軌跡の延長線上に干渉する位置まで延出されていることを要旨とする。   According to a second aspect of the present invention, in the multidirectional operation device according to the first aspect, the detected portion is constituted by a plurality of protrusions provided on a shaft side surface of the operation shaft, and the contactless detection The portion is provided at a position corresponding to each protrusion around the operation shaft, and the tilt detection part is disposed to face each protrusion, and the rotation detection part is separated from the tilt detection part. Extending to a position that interferes with the rotation trajectory of each of the protrusions as the operating shaft rotates, the axial movement detection site extends from the tilt detection site to a position that interferes with the extension line of the axial movement trajectory of each of the projections. The summary is that it has been issued.

上記構成によると、傾動検出部位、回転検出部位及び軸移動検出部位は一体に構成されているため、無接点式検出部の設置を容易に行うことができる。また、こうした無接点式検出部は、操作軸の軸側面に設けられた被検出部としての複数の突部にそれぞれ対応して複数個設けられているため、操作軸の各種操作をより確実に検出可能となる。   According to the above configuration, since the tilt detection part, the rotation detection part, and the axial movement detection part are integrally configured, the contactless detection unit can be easily installed. In addition, since there are a plurality of such contactless detectors corresponding to a plurality of protrusions as detected portions provided on the side surface of the operation shaft, various operations of the operation shaft can be performed more reliably. It can be detected.

請求項３に記載の発明では、請求項１または請求項２に記載の多方向操作装置において、前記無接点式検出部を構成する各種の検出部位とそれぞれ個別に電気的に接続され、それら検出部位による前記被検出部の検出パターンに基づいて前記操作軸の操作方向を判断して対応する制御を行う制御手段を備えることを要旨とする。   According to a third aspect of the present invention, in the multi-directional operation device according to the first or second aspect, each of the various detection parts constituting the non-contact type detection unit is electrically connected individually and detected. The gist of the present invention is to provide control means for determining the operation direction of the operation axis based on the detection pattern of the detected part by the part and performing corresponding control.

上記構成によると、各種検出部位による検出信号は一旦制御手段に入力され、該制御手段により、各種検出部位による検出パターンに基づく制御が行われる。このため、操作軸の多方向への操作に基づく個別の制御を確実に行うことができる。   According to the above configuration, detection signals from various detection parts are once input to the control means, and control based on detection patterns from the various detection parts is performed by the control means. For this reason, the individual control based on the operation of the operation shaft in multiple directions can be reliably performed.

以上詳述したように、本発明によれば、操作を高い信頼性で検出することができる。   As described above in detail, according to the present invention, an operation can be detected with high reliability.

（傾動操作時における検出態様）
詳しくは、例えば図６（ａ）に示すように、操作軸１２が矢印Ａ１方向に傾動操作されると、図７にも併せ示すように、第１突部１８ａが第１検出部１３の第１傾動検出部位１３ａに当接し、該第１傾動検出部位１３ａがＯＮ状態（検出状態）となる。なお、この状態において他の検出部位１３ｂ，１３ｃ，１４ａ〜１４ｃ，１５ａ〜１５ｃ，１６ａ〜１６ｃは、各突部１８ａ〜１８ｄが当接されないためＯＦＦ状態（非検出状態）となる。すなわち、操作軸１２が矢印Ａ１方向に傾動操作された際には、第１傾動検出部位１３ａのみがＯＮ状態となる。 (Detection mode during tilting operation)
Specifically, for example, as shown in FIG. 6A, when the operation shaft 12 is tilted in the direction of the arrow A1, the first protrusion 18a is connected to the first detection unit 13 as shown in FIG. The first tilt detection part 13a comes into contact with the first tilt detection part 13a and is turned on (detected state). In this state, the other detection portions 13b, 13c, 14a to 14c, 15a to 15c, and 16a to 16c are in the OFF state (non-detection state) because the protrusions 18a to 18d are not in contact with each other. That is, when the operation shaft 12 is tilted in the direction of the arrow A1, only the first tilt detection portion 13a is turned on.

また、操作軸１２が矢印Ａ２方向に操作された場合には、第３突部１８ｃの当接により第３傾動検出部位１５ａのみがＯＮ状態となる。同様に、操作軸１２が矢印Ａ３方向に操作された場合には第２突部１８ｂの当接により第２傾動検出部位１４ａのみがＯＮ状態となり、操作軸１２が矢印Ａ４方向に操作された場合には第４突部１８ｄの当接により第４傾動検出部位１６ａのみがＯＮ状態となる。   When the operation shaft 12 is operated in the direction of the arrow A2, only the third tilt detection part 15a is turned on by the contact of the third protrusion 18c. Similarly, when the operation shaft 12 is operated in the arrow A3 direction, only the second tilt detection portion 14a is turned on by the contact of the second protrusion 18b, and the operation shaft 12 is operated in the arrow A4 direction. Only the fourth tilt detection portion 16a is turned on by the contact of the fourth protrusion 18d.

（回動操作における検出態様）
一方、図６（ｂ）に示すように、操作軸１２が矢印Ｂ１方向に回転操作されると、図７にも併せ示すように、第１突部１８ａが第１検出部１３の第１回転検出部位１３ｂに当接するとともに、第３突部１８ｃが第３検出部１５の第３回転検出部位１５ｂに当接することにより、第１回転検出部位１３ｂ及び第３回転検出部位１５ｂがＯＮ状態となる。 (Detection mode in turning operation)
On the other hand, as shown in FIG. 6B, when the operation shaft 12 is rotated in the direction of the arrow B <b> 1, the first protrusion 18 a is rotated by the first rotation of the first detection unit 13 as shown in FIG. 7. The first rotation detection part 13b and the third rotation detection part 15b are turned on by contacting the detection part 13b and the third protrusion 18c coming into contact with the third rotation detection part 15b of the third detection part 15. .

また、操作軸１２が矢印Ｂ２方向に操作された場合には、第２突部１８ｂが第２検出部１４の第２回転検出部位１４ｂに当接するとともに、第４突部１８ｄが第４検出部１６の第４回転検出部位１６ｂに当接することにより、第２回転検出部位１４ｂ及び第４回転検出部位１６ｂがＯＮ状態となる。   When the operation shaft 12 is operated in the direction of the arrow B2, the second protrusion 18b comes into contact with the second rotation detection portion 14b of the second detector 14, and the fourth protrusion 18d is the fourth detector. The second rotation detection part 14b and the fourth rotation detection part 16b are turned on by coming into contact with the 16th fourth rotation detection part 16b.

（軸移動操作における検出態様）
さらに、図６（ｃ）及び図７に示すように、操作軸１２が矢印Ｃ方向に軸移動操作されると、第１〜第４突部１８ａ〜１８ｄの全てが、対応する検出部１３〜１６の第１〜第４軸移動検出部位１３ｃ，１４ｃ，１５ｃ，１６ｃに当接することにより、それら第１〜第４軸移動検出部位１３ｃ，１４ｃ，１５ｃ，１６ｃが全てＯＮ状態となる。 (Detection mode in axis movement operation)
Further, as shown in FIGS. 6C and 7, when the operation shaft 12 is operated to move in the direction of arrow C, all of the first to fourth protrusions 18 a to 18 d are detected by the corresponding detection units 13 to 13. By contacting the sixteenth first to fourth axis movement detection parts 13c, 14c, 15c, and 16c, all of the first to fourth axis movement detection parts 13c, 14c, 15c, and 16c are turned on.

このように、操作軸１２の傾動操作、回転操作、軸移動操作のそれぞれにおいて、各種検出部位１３ａ〜１３ｃ，１４ａ〜１４ｃ，１５ａ〜１５ｃ，１６ａ〜１６ｃの検出パターンが全て異なるため、制御部２１は、該検出パターンに基づいて操作軸１２の操作を認識可能となる。そして、制御部２１は、その認識した操作に基づいて、対応する制御対象の駆動等を制御する。   As described above, since the detection patterns of the various detection portions 13a to 13c, 14a to 14c, 15a to 15c, and 16a to 16c are all different in each of the tilt operation, the rotation operation, and the axis movement operation of the operation shaft 12, the control unit 21 Can recognize the operation of the operation shaft 12 based on the detection pattern. And the control part 21 controls the drive of a corresponding control object, etc. based on the recognized operation.

したがって、本実施形態によれば以下のような効果を得ることができる。
（１）操作軸１２の多方向（図１に示す矢印Ａ１〜Ａ４，Ｂ１，Ｂ２，Ｃの各方向）への操作は、無接点式検出センサによって構成された第１検出部１３〜第４検出部１６によって検出可能となる。このため、経年劣化や絶縁物の付着等に起因する接点不良の発生を確実に防止することができ、該操作軸１２の操作を検出することができる。 Therefore, according to the present embodiment, the following effects can be obtained.
(1) The operation of the operation shaft 12 in multiple directions (the directions of arrows A1 to A4, B1, B2, and C shown in FIG. 1) is performed by the first detection unit 13 to the fourth configured by contactless detection sensors. Detection is possible by the detector 16. For this reason, it is possible to reliably prevent the occurrence of contact failure due to deterioration over time, adhesion of an insulator, and the like, and the operation of the operation shaft 12 can be detected.

また、第１〜第４傾動検出部位１３ａ，１４ａ，１５ａ，１６ａによって操作軸１２の矢印Ａ１〜Ａ４方向への傾動方向が検出され、第１〜第４回転検出部位１３ｂ，１４ｂ，１５ｂ，１６ｂによって矢印Ｂ１，Ｂ２方向への操作軸の回転操作が検出され、第１〜第４軸移動検出部位１３ｃ，１４ｃ，１５ｃ，１６ｃによって矢印Ｃ方向への操作軸の軸方向への移動が検出される。すなわち、第１〜第４検出部１３〜１６を操作軸１２の近傍に配設することにより、操作軸１２の種々の方向への操作を検出することができる。よって、多方向操作装置４を、高い信頼性を有する多機能操作装置として好適に用いることができる。   In addition, the first to fourth tilt detection parts 13a, 14a, 15a and 16a detect the tilt direction of the operation shaft 12 in the directions of arrows A1 to A4, and the first to fourth rotation detection parts 13b, 14b, 15b and 16b. Is used to detect the rotation of the operation shaft in the directions of arrows B1 and B2, and the first to fourth axis movement detection portions 13c, 14c, 15c, and 16c detect the movement of the operation shaft in the direction of arrow C in the axial direction. The That is, by arranging the first to fourth detection units 13 to 16 in the vicinity of the operation shaft 12, the operation of the operation shaft 12 in various directions can be detected. Therefore, the multidirectional operating device 4 can be suitably used as a multifunctional operating device having high reliability.

Therefore, the detection units 13 to 16 can be easily installed. Moreover, since these detection parts 13-16 are provided with two or more corresponding to each of the some protrusions 18a-18d as a to-be-detected part provided in the axial side surface of the operating shaft 12, various kinds of the operating shaft 12 are provided. The operation can be detected more reliably.

（３）各種検出部位１３ａ〜１３ｃ，１４ａ〜１４ｃ，１５ａ〜１５ｃ，１６ａ〜１６ｃによる検出信号は制御部２１に個別に入力され、該制御部２１により、各種検出部位１３ａ〜１３ｃ，１４ａ〜１４ｃ，１５ａ〜１５ｃ，１６ａ〜１６ｃによる検出パターンに基づく制御が行われる。このため、操作軸１２の多方向への操作に基づく個別の制御を確実に行うことができる。   (3) Detection signals from the various detection sites 13a to 13c, 14a to 14c, 15a to 15c, and 16a to 16c are individually input to the control unit 21, and the control unit 21 causes the various detection sites 13a to 13c and 14a to 14c to be detected. , 15a to 15c and 16a to 16c are controlled based on the detection pattern. For this reason, individual control based on the operation of the operation shaft 12 in multiple directions can be reliably performed.
