Abstract

<P>PROBLEM TO BE SOLVED: To provide a coupling structure between a sensor and an operation lever requiring no mechanism holding the operation lever. <P>SOLUTION: Since a projection part 6 formed in a first rotational body 4 is brought into contact with a recess part 11 formed in a second rotational body without any gap in the rotational direction R, the first rotational body 4 and the second rotational body 8 rotate together. Therefore, rotational energization of one of the first rotational body 4 and the second rotational body to the other is not necessary, so that a mechanism holding the operation lever 1 can be omitted, and consequently, a structure around the operation lever 1 is simplified. Since the projection part 6 and the recess part 11 are resiliently deformable freely relatively in the rotational direction R, they can be brought into contact with each other without any gap while a positional shift between them is absorbed even if the positional shift occurs in the rotational direction R between the projection part 6 and the recess part 11. Consequently, coupling work between the first rotational body 4 and the second rotational body 8 can be facilitated. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

この発明は、操作レバーとセンサーの連結構造に関するものである。 The present invention relates to a connecting structure of an operation lever and a sensor.

例えば、車両用の自動変速装置には、車内側へ突出した操作レバーが設けられている。この操作レバーは基端部を中心に回転自在で、基端部には操作レバーの回転角度を検出するセンサーが設けられている。そして、センサーで検出した回転角度に相当する分だけ、アクチュエータが自動変速機のレンジ切換機構を作動させ、自動変速機のレンジ（Ｐ，Ｒ，Ｎ，Ｄなど）を自動的に切り換えるようになっている。 For example, an automatic transmission for a vehicle is provided with an operation lever that protrudes toward the inside of the vehicle. The operation lever is rotatable about a base end portion, and a sensor for detecting a rotation angle of the operation lever is provided at the base end portion. Then, the actuator operates the automatic transmission range switching mechanism by an amount corresponding to the rotation angle detected by the sensor, and automatically switches the automatic transmission range (P, R, N, D, etc.). ing.

操作レバーの基端部には、操作レバーと直交する回転軸を中心に操作レバーと一体的に回転自在な第１回転体が設けられている。また、センサーにも回転自在な第２回転体が設けられている。そして、第１回転体と第２回転体とを、同軸で且つ同回転するように連結している（例えば、特許文献１参照）。 The base end portion of the operation lever is provided with a first rotating body that is rotatable integrally with the operation lever around a rotation axis orthogonal to the operation lever. The sensor is also provided with a rotatable second rotating body. And the 1st rotary body and the 2nd rotary body are connected so that it may rotate coaxially and the same (for example, refer to patent documents 1).

第１回転体と第２回転体には、回転方向で互いに当接する突片が回転軸を挟んだ対向位置に対向状態で形成されている。そして、第２回転体とセンサーの内面との間には、第２回転体の突片を第１回転体の突片に押し当てて両者の当接状態を維持するためのバネが設けられている。従って、操作レバーにより第１回転体をどちらの方向に回転させても、第２回転体は第１回転体に追従して同じように回転する。また、別物である第１回転体と第２回転体を回転方向で当接させる構造のため、第１回転体と第２回転体とは、回転方向での位置ずれが吸収された状態で必ず当接状態となり、連結作業が容易である。
特開２００３−３０１９４２号公報 On the first rotating body and the second rotating body, projecting pieces that are in contact with each other in the rotational direction are formed in opposing states at opposing positions sandwiching the rotating shaft. And between the 2nd rotary body and the inner surface of a sensor, the spring for pressing the protrusion of a 2nd rotary body on the protrusion of a 1st rotary body, and maintaining both contact state is provided. Yes. Therefore, no matter which direction the first rotating body is rotated by the operating lever, the second rotating body follows the first rotating body and rotates in the same way. In addition, since the first rotating body and the second rotating body, which are separate objects, are brought into contact with each other in the rotation direction, the first rotation body and the second rotation body are always in a state where the positional deviation in the rotation direction is absorbed. The contact state is achieved, and the connecting work is easy.

しかしながら、このような従来の技術にあっては、バネにより、第２回転体の突片を第１回転体の突片に押し当てる構造のため、バネ力が第１回転体を介して操作レバーに伝わり、操作レバーを回転させようとする。そのため、操作レバーを、バネ力以上のトルクを有するチェック機構（弾性突出するボールでチェック山を乗り越える機構）により、レンジに対応する角度差ごとに保持する必要がある。従って、操作レバー周辺の構造が複雑であった。 However, in such a conventional technique, the structure is such that the projecting piece of the second rotating body is pressed against the projecting piece of the first rotating body by a spring, so that the spring force is operated via the first rotating body. And tries to rotate the control lever. For this reason, it is necessary to hold the operation lever for each angle difference corresponding to the range by a check mechanism having a torque equal to or greater than the spring force (a mechanism that climbs over the check mountain with an elastic protruding ball). Therefore, the structure around the operation lever is complicated.

本発明は、このような従来の技術に着目してなされたものであり、操作レバーを保持する機構が不要な操作レバーとセンサーの連結構造を提供するものである。 The present invention has been made paying attention to such a conventional technique, and provides a connection structure of an operation lever and a sensor that does not require a mechanism for holding the operation lever.

請求項１記載の発明は、回転軸を中心に該回転軸に直交する回転方向で回転自在な操作レバーに、回転軸を中心に操作レバーと一体的に回転する第１回転体を設け、センサーに、該センサーにより回転角度を検出自在な第２回転体を回転自在に設け、第１回転体と第２回転体とを、同軸で且つ同回転するように連結する操作レバーとセンサーの連結構造であって、前記第１回転体又は第２回転体の、一方側に他方側へ向けて突出する凸部を形成し、他方側に凸部と回転方向で隙間なく接する凹部を形成すると共に、凸部と凹部とは、回転方向において相対的に弾性変位自在であることを特徴とする。 According to a first aspect of the present invention, a first rotating body that rotates integrally with an operation lever about a rotation axis is provided on an operation lever that is rotatable about a rotation axis in a rotation direction orthogonal to the rotation axis, and a sensor. In addition, a second rotating body whose rotation angle can be detected by the sensor is rotatably provided, and an operating lever and sensor connecting structure for connecting the first rotating body and the second rotating body so as to rotate in the same axis. In the first rotating body or the second rotating body, a convex portion that protrudes toward the other side is formed on one side, and a concave portion that is in contact with the convex portion without any gap in the rotation direction is formed on the other side, The convex part and the concave part are characterized by being relatively elastically displaceable in the rotational direction.

請求項１記載の発明によれば、第１回転体又は第２回転体の、一方側に形成された凸部が、他方側に形成された凹部と、回転方向で隙間なく接するため、第１回転体と第２回転体とは同じ回転をする。従って、第１回転体と第２回転体の一方を他方に対して回転付勢する必要がなく、操作レバーを保持する機構が不要となり、操作レバー周辺の構造が簡略化される。また、凸部と凹部とは、回転方向において相対的に弾性変位自在であるため、凸部と凹部との間に回転方向において位置ずれがあったとしても、その位置ずれを吸収した状態で、両者は隙間なく接することができる。従って、第１回転体と第２回転体との連結作業が容易である。 According to the first aspect of the present invention, the convex portion formed on one side of the first rotating body or the second rotating body is in contact with the concave portion formed on the other side without any gap in the rotation direction. The rotating body and the second rotating body rotate the same. Therefore, it is not necessary to urge one of the first rotating body and the second rotating body with respect to the other, and a mechanism for holding the operating lever becomes unnecessary, and the structure around the operating lever is simplified. Further, since the convex portion and the concave portion are relatively elastically displaceable in the rotational direction, even if there is a positional deviation in the rotational direction between the convex portion and the concave portion, Both can touch without a gap. Therefore, the connecting operation between the first rotating body and the second rotating body is easy.

操作レバーを保持する機構が不要な操作レバーとセンサーの連結構造を提供する、という目的を、回転軸を中心に該回転軸に直交する方向で回転自在な操作レバーに、回転軸を中心に操作レバーと一体的に回転する第１回転体を設け、センサーに、該センサーにより回転角度を検出自在な第２回転体を回転自在に設け、第１回転体と第２回転体とを、同軸で且つ同回転するように連結する操作レバーとセンサーの連結構造であって、前記第１回転体又は第２回転体の、一方側に他方側へ向けて突出する凸部を形成し、他方側に凸部と回転方向で隙間なく接する凹部を形成すると共に、凸部と凹部とが、回転方向において相対的に弾性変位自在であることで、実現した。以下、本発明の最良の実施形態を図面に基づいて説明する。 The purpose of providing a connection structure between the operation lever and the sensor that does not require a mechanism to hold the operation lever is to operate the operation lever around the rotation axis as the operation lever that can rotate around the rotation axis in the direction perpendicular to the rotation axis. A first rotating body that rotates integrally with the lever is provided, a second rotating body that can detect a rotation angle by the sensor is rotatably provided, and the first rotating body and the second rotating body are coaxially arranged. And a connecting structure of an operation lever and a sensor connected so as to rotate in the same manner, wherein a convex portion projecting toward the other side is formed on one side of the first rotating body or the second rotating body, and the other side is formed. This is realized by forming a concave portion that is in contact with the convex portion without any gap in the rotational direction, and that the convex portion and the concave portion are relatively elastically displaceable in the rotational direction. DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings.

図１〜図３は、本発明の第１実施例を示す図である。自動車の自動変速装置の操作レバー１は、先端側の図示せぬノブを操作することにより、基端部に形成された回転軸２を中心に、該回転軸２に直交する回転方向Ｒに回転させることができる。図１は、操作レバー１の実際の搭載状態を９０度変換して図示している。以下、実際の搭載方向でなく、図１の方向性で説明する。 1 to 3 are views showing a first embodiment of the present invention. An operation lever 1 of an automatic transmission of an automobile is rotated in a rotation direction R perpendicular to the rotation shaft 2 around a rotation shaft 2 formed at a base end portion by operating a knob (not shown) on the distal end side. Can be made. FIG. 1 shows the actual mounting state of the operation lever 1 converted by 90 degrees. Hereinafter, description will be made with reference to the directionality of FIG. 1 instead of the actual mounting direction.

回転軸２の上面に非円形のボス部３が形成されている。このボス部３に、第１回転体４の中心に形成された係合孔５が係合している。係合孔５はボス部３に合致した形状で、相対的に回転することはできず、第１回転体４は回転軸２と一体的に回転する。第１回転体４は金属製で、係合孔５を挟んだ両側位置に上向きに折り曲げた突片状の凸部６が形成されている。 A non-circular boss portion 3 is formed on the upper surface of the rotating shaft 2. An engagement hole 5 formed at the center of the first rotating body 4 is engaged with the boss portion 3. The engagement hole 5 has a shape matching the boss portion 3 and cannot rotate relatively, and the first rotating body 4 rotates integrally with the rotating shaft 2. The first rotating body 4 is made of metal, and projecting piece-like convex portions 6 bent upward are formed at both side positions sandwiching the engagement hole 5.

一方、センサー７には内部に第２回転体８が回転自在に設けられる。センサー７は第２回転体８の回転角度を検出することができる。そして、検出した角度に応じ、図示せぬレンジ切換機構のアクチュエータに信号を出力する。 On the other hand, a second rotating body 8 is rotatably provided in the sensor 7. The sensor 7 can detect the rotation angle of the second rotating body 8. Then, a signal is output to an actuator of a range switching mechanism (not shown) according to the detected angle.

第２回転体８は、樹脂製の中心筒９の両側に、弾性体（弾性ゴム）製の両端部１０を一体成形した構造をしており、中心筒９を利用してセンサー７の内部に回動自在に組み付けられる。両端部１０の下面には、回転軸２を中心したラジアル方向に沿うスリット状の凹部１１が形成されている。この凹部１１は、第１回転体４の凸部６に相応する幅を有し、凸部６よりも長い長さを有している。そして、この凹部１１内に、凸部６を挿入することにより、第１回転体４と第２回転体８とを連結することができる。凹部１１内に挿入された凸部６は、凹部１１の内面と隙間なく接する。 The second rotating body 8 has a structure in which both end portions 10 made of an elastic body (elastic rubber) are integrally formed on both sides of a resin center tube 9. It can be assembled freely. On the lower surfaces of the both end portions 10, slit-like concave portions 11 are formed along the radial direction centering on the rotation shaft 2. The concave portion 11 has a width corresponding to the convex portion 6 of the first rotating body 4 and has a length longer than the convex portion 6. And the 1st rotary body 4 and the 2nd rotary body 8 can be connected by inserting the convex part 6 in this recessed part 11. FIG. The convex portion 6 inserted into the concave portion 11 is in contact with the inner surface of the concave portion 11 without a gap.

この実施例によれば、凸部６と凹部１１とが、回転方向Ｒにおいて、隙間なく接するため、操作レバー１と一体的に回転する第１回転体４に合わせて、第２回転体８も同じ回転をする。従って、従来のように、第２回転体８を第１回転体４に対して回転付勢する必要がなく、操作レバー１を保持する機構が不要となる。そのため、操作レバー１の周辺の構造が簡略になる。また、凹部１１の方が凸部６よりも長いため、回転方向Ｒにおける回転動作の間に、凸部６の位置が凹部１１の長手方向（ラジアル方向）において変位しても、その変位を吸収することができる。 According to this embodiment, since the convex portion 6 and the concave portion 11 are in contact with each other in the rotation direction R without a gap, the second rotating body 8 is also adapted to the first rotating body 4 that rotates integrally with the operation lever 1. Do the same rotation. Therefore, unlike the prior art, it is not necessary to urge the second rotating body 8 to rotate with respect to the first rotating body 4, and a mechanism for holding the operation lever 1 becomes unnecessary. Therefore, the structure around the operation lever 1 is simplified. Further, since the concave portion 11 is longer than the convex portion 6, even if the position of the convex portion 6 is displaced in the longitudinal direction (radial direction) of the concave portion 11 during the rotation operation in the rotation direction R, the displacement is absorbed. can do.

更に、第２回転体８において、凹部１１が弾性体製の両端部１０に形成されているため、凸部６と凹部１１とは、回転方向Ｒにおいて相対的に弾性変位自在である。従って、凸部６を凹部１１内に挿入する際に、凸部６と凹部１１との間に回転方向Ｒにおける位置ずれがあったとしても、その位置ずれを吸収した状態で、凸部６を凹部１１内へ確実に挿入することができる。従って、第１回転体４と第２回転体８との連結作業が容易である。 Furthermore, in the 2nd rotary body 8, since the recessed part 11 is formed in the both ends 10 made from an elastic body, the convex part 6 and the recessed part 11 are relatively elastically displaceable in the rotation direction R. As shown in FIG. Accordingly, when the convex portion 6 is inserted into the concave portion 11, even if there is a positional deviation in the rotation direction R between the convex portion 6 and the concave portion 11, the convex portion 6 is inserted in a state in which the positional deviation is absorbed. It can be reliably inserted into the recess 11. Therefore, the connection work of the 1st rotary body 4 and the 2nd rotary body 8 is easy.

図４及び図５は、本発明の第２実施例を示す図である。この実施例では、第２回転体１２の両端部１３を中心筒１４と一体の樹脂製とし、且つ下方が開放したケース状にした。そして、このケース状の両端部１３内に、相応する形状の弾性ゴムによる弾性体１５を挿入する。弾性体１５には、下面から凹部１１が貫通状態で形成されている。 4 and 5 are views showing a second embodiment of the present invention. In this embodiment, both end portions 13 of the second rotating body 12 are made of a resin integral with the central cylinder 14 and are formed in a case shape with the lower part opened. Then, an elastic body 15 made of elastic rubber having a corresponding shape is inserted into both end portions 13 of the case shape. The elastic body 15 is formed with a recess 11 penetrating from the lower surface.

この実施例によれば、第２回転体１２を樹脂部材と弾性部材で一体成形せず、互いに分けて成形した樹脂部材と弾性部材とを組み合わせて形成したため、製造コストの面で有利である。その他の構成及び作用効果は、先の実施例と同様に付き、共通する部分には同一の符号を付し、重複する説明は省略する。 According to this embodiment, the second rotating body 12 is not integrally formed with the resin member and the elastic member, but is formed by combining the resin member and the elastic member that are separately molded, which is advantageous in terms of manufacturing cost. Other configurations and operational effects are the same as those in the previous embodiment, and common portions are denoted by the same reference numerals, and redundant description is omitted.

図６及び図７は、本発明の第３実施例を示す図である。この実施例の第２回転体１６も、第２実施例と同様に、樹脂製の中心筒１４とケース状の両端部１３を有している。異なるのは、両端部１３内に金属クリップ状の弾性体１７を挿入している点である。すなわち、弾性体１７は両端に互いに弾接する押返部１７ａを有し、この押返部１７ａの間で凹部１８を形成している。従って、凸部６は押返部１７ａ間の凹部１８内に挿入され、押返部１７ａが凸部６に対して隙間なく接する。押返部１７ａの長さは、凸部６の長さよりもあり、回転時における凸部６のラジアル方向での変位を吸収する。その他の構成及び作用効果は、先の実施例と同様に付き、共通する部分には同一の符号を付し、重複する説明は省略する。 6 and 7 are views showing a third embodiment of the present invention. Similarly to the second embodiment, the second rotating body 16 of this embodiment also has a resin center tube 14 and case-shaped end portions 13. The difference is that a metal clip-like elastic body 17 is inserted into both end portions 13. That is, the elastic body 17 has pressing portions 17a that elastically contact each other at both ends, and a recess 18 is formed between the pressing portions 17a. Accordingly, the convex portion 6 is inserted into the concave portion 18 between the push-back portions 17a, and the push-back portion 17a contacts the convex portion 6 without a gap. The length of the pushing-back portion 17a is longer than the length of the convex portion 6, and absorbs the displacement of the convex portion 6 in the radial direction during rotation. Other configurations and operational effects are the same as those in the previous embodiment, and common portions are denoted by the same reference numerals, and redundant description is omitted.

以上の実施例では、第１回転体４に凸部６を形成し、第２回転体８、１２、１６に凹部１１、１８を形成したが、第１回転体４と第２回転体８、１２、１６の形状を逆にしても良い。 In the above embodiment, the convex portion 6 is formed on the first rotating body 4 and the concave portions 11 and 18 are formed on the second rotating bodies 8, 12, and 16. However, the first rotating body 4 and the second rotating body 8, The shapes of 12 and 16 may be reversed.
