Description

【0001】
【発明の属する技術分野】
本発明は、自動車のドアロック検出スイッチ機構などのスイッチ機構に関する。
【0002】
【従来の技術】
従来、ドアロック検出スイッチはルームランプの点滅を制御するために1箇所・1接点の検出点のみでよかったので、通例としてリミットスイッチを用いていた。しかし近年、電動ドアクローザー機構の導入により、半ドアの検出とECU信号の取出しなども必要となり、2箇所・2接点以上の検出点が要求されるようになってきた。
【0003】
【発明が解決しようとする課題】
そうすると、リミットスイッチが2個以上必要となってコストアップになる上、微妙な半ドア位置の検出精度に問題があった。本発明では、比較的低コストで精度のよいロータリースイッチ方式によるスイッチ機構を提供することを目的とする。
【0004】
【課題を解決するための手段】
本発明を要約すると、作動ピンの移動に基づいて開閉されるスイッチを備えたスイッチ機構であって、前記作動ピンの移動により回転される回転板と、この回転板に固定された伝達ピンと、前記回転板の回転による前記伝達ピンの移動によりバネによる付勢力に逆らってスライドされるアームと、このアームのスライドにより回転動作されるロータリースイッチと、前記アーム、ロータリースイッチ及びバネを収めるケースとを備えたスイッチ機構である。また、他の発明として、作動ピンの移動に基づいて開閉されるスイッチを備えたスイッチ機構であって、前記作動ピンの移動により回転される回転板と、この回転板に固定された伝達ピンと、前記回転板の回転による前記伝達ピンの移動によりスライドされるアームと、このアームのスライドにより回転動作されるロータリースイッチと、前記アーム及びロータリースイッチを収めるケースとを備え、前記アームには前記伝達ピンが戻る時に当該アームを元の位置に引っ掛けて戻す引掛部を設けたスイッチ機構がある。
【0005】
【発明の実施の形態】
次に、本発明の実施形態を説明するが、それはあくまで本発明に基づいて採択された例示的な実施形態であり、本発明をその実施形態に特有な事項に基づいて限定解釈してはならず、本発明の技術的範囲は、請求項に示した事項さらにはその事項と実質的に等価である事項に基づいて定めなければならない。
【0006】
図1〜3の実施形態は、作動ピン1の移動に基づいて開閉されるスイッチ2を備えたスイッチ機構である。そして、前記作動ピン1の移動により回転される回転板3と、この回転板3に固定された伝達ピン4と、前記回転板3の回転による前記伝達ピン4の移動によりバネ5による付勢力に逆らってスライドされるアーム6と、このアーム6のスライドにより回転動作されるロータリースイッチ2と、前記アーム6、ロータリースイッチ2及びバネ5を収めるケース7とを備えている。
【0007】
さらに詳述すれば、作動ピン1は例えば、図外のドア開閉に伴って移動するストライカーであり、回転板3の切り欠き8に位置され、ケース7のガイド溝9に沿って移動する作動ピン1の移動に伴い、回転板3が所定角度の範囲で回転する。なお、回転板3はケース7に設けた軸10の周りに回転され、軸10には巻きつけられたバネ11が伝達ピン4を元の位置に戻りやすくしている。ロータリースイッチ2は、内部に複数の固定接片(非図示)とこれらに対向した複数の回転接片12を備える。図1の作動ピン1がガイド溝9の入口から内奥に移動して図2のようになる際、回転板3は反時計回りに回転して、伝達ピン4はアーム6を押し込み、アーム6の先端の凹部14はロータリースイッチ2の凸部13を回転させ、ロータリースイッチ2を回転動作させる。また、作動ピン1がガイド溝9の入口に戻ると、バネ5の付勢力でロータリースイッチ2は元の位置に戻り、回転板3も時計回りに回転する。このように、アーム6の進退に伴って回転接片12が回転して、回転接片12と固定接片との接離状態が決まる。
【0008】
図4〜6では、前記バネ5を省き、アーム6には伝達ピン4が戻る時に当該アーム6を元の位置に引っ掛けて戻す引掛部14を設けたスイッチ機構である。
【0009】
本実施形態によれば、作動ピン1により回転する回転板3とアーム6を介してロータリースイッチ2を作動できたため、ロータリースイッチ2本来の精度のよい接離状態を利用可能となり、比較的低コストで製造できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a switch mechanism such as an automobile door lock detection switch mechanism.
[0002]
[Prior art]
Conventionally, since the door lock detection switch only needs to detect one point and one contact point to control the blinking of the room lamp, a limit switch is usually used. However, in recent years, with the introduction of the electric door closer mechanism, it has become necessary to detect a half-door and take out an ECU signal, so that two or more detection points are required.
[0003]
[Problems to be solved by the invention]
Then, two or more limit switches are required, which increases the cost, and also has a problem in the detection accuracy of the delicate half-door position. It is an object of the present invention to provide a relatively low-cost and accurate switch mechanism using a rotary switch system.
[0004]
[Means for Solving the Problems]
In summary, the present invention provides a switch mechanism including a switch that is opened and closed based on movement of an operation pin, the rotation plate being rotated by movement of the operation pin, a transmission pin fixed to the rotation plate, An arm that slides against a biasing force of a spring by movement of the transmission pin due to rotation of the rotating plate, a rotary switch that is rotated by the sliding of the arm, and a case that houses the arm, the rotary switch, and the spring. Switch mechanism. According to another aspect of the present invention, there is provided a switch mechanism including a switch that is opened and closed based on movement of an operation pin, wherein the rotation plate is rotated by movement of the operation pin, and a transmission pin fixed to the rotation plate; An arm slid by the movement of the transmission pin due to the rotation of the rotary plate, a rotary switch rotated by sliding the arm, and a case for accommodating the arm and the rotary switch; There is a switch mechanism provided with a hook portion that hooks the arm back to the original position when the arm returns.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described. However, it is an exemplary embodiment adopted based on the present invention, and the present invention should not be interpreted in a limited manner based on matters specific to the embodiment. Instead, the technical scope of the present invention should be determined on the basis of the matters stated in the claims and matters substantially equivalent to the matters.
[0006]
The embodiment of FIGS. 1 to 3 is a switch mechanism including a switch 2 that is opened and closed based on movement of an operation pin 1. The rotating plate 3 rotated by the movement of the operating pin 1, the transmission pin 4 fixed to the rotating plate 3, and the urging force of the spring 5 due to the movement of the transmission pin 4 due to the rotation of the rotating plate 3. An arm 6 is slid in the opposite direction, a rotary switch 2 rotated by the sliding of the arm 6, and a case 7 for accommodating the arm 6, the rotary switch 2 and the spring 5.
[0007]
More specifically, the operating pin 1 is, for example, a striker that moves in accordance with opening and closing of a door (not shown), and is located in the notch 8 of the rotating plate 3 and moves along the guide groove 9 of the case 7. With the movement of 1, the rotating plate 3 rotates within a predetermined angle range. The rotating plate 3 is rotated around a shaft 10 provided on the case 7, and a spring 11 wound around the shaft 10 makes it easy for the transmission pin 4 to return to its original position. The rotary switch 2 includes a plurality of fixed contact pieces (not shown) and a plurality of rotary contact pieces 12 opposed thereto. When the operating pin 1 of FIG. 1 moves inward from the entrance of the guide groove 9 to become as shown in FIG. 2, the rotating plate 3 rotates counterclockwise, and the transmission pin 4 pushes the arm 6 and the arm 6 The concave portion 14 at the tip of the rotary switch 2 rotates the convex portion 13 of the rotary switch 2 to rotate the rotary switch 2. When the operating pin 1 returns to the entrance of the guide groove 9, the rotary switch 2 returns to the original position by the urging force of the spring 5, and the rotary plate 3 also rotates clockwise. In this manner, the rotating contact piece 12 rotates with the advance and retreat of the arm 6, and the contact / separation state between the rotating contact piece 12 and the fixed contact piece is determined.
[0008]
FIGS. 4 to 6 show a switch mechanism in which the spring 5 is omitted, and the arm 6 is provided with a hook portion 14 which hooks the arm 6 to the original position when the transmission pin 4 returns.
[0009]
According to the present embodiment, the rotary switch 2 can be operated via the rotary plate 3 and the arm 6 which are rotated by the operating pin 1, so that the original accurate contact / separation state of the rotary switch 2 can be used, and the cost is relatively low. It can be manufactured by
