Description

本発明は、スロットルグリップの回転操作に基づいて車両の駆動源が制御されるスロットルグリップ装置に関するものである。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a throttle grip device for controlling a driving source of a vehicle based on rotating operation of a throttle grip.

近時の二輪車においては、スロットルグリップの回転角度をポテンショメータ等のスロットル開度センサにて検出し、その検出値を電気信号として当該二輪車が搭載する電子制御装置等に送るよう構成されたものが普及されるに至っている。そして、かかる検出信号に基づき電子制御装置が所定の演算を行い、その演算結果に基づいてエンジンの点火時期、吸気バルブ若しくはスロットルバルブの開閉が制御されるようになっている。 In recent motorcycles, the rotation angle of the throttle grip is detected by a throttle opening sensor such as a potentiometer, and the detected value is sent as an electric signal to the electronic control device mounted on the motorcycle. It has reached the point where it is done. Based on the detection signal, the electronic control unit performs a predetermined calculation, and based on the result of the calculation, the ignition timing of the engine and the opening and closing of the intake valve or throttle valve are controlled.

例えば、特許文献1には、スロットルグリップと連動して回転する連動部材と、連動部材に取り付けられた磁石と、磁石からの磁力の変化を検出することによりスロットルグリップの回転角度を検出可能な磁気センサと、スロットルグリップに対して初期位置に戻る方向に付勢するリターンスプリングとを具備し、これら連動部材、磁石、磁気センサ及びリターンスプリングがハンドルパイプ内に配設されたものが開示されている。かかる従来のスロットルグリップ装置によれば、主な構成部品をハンドルパイプ内に配設するので、ハンドルパイプ内のスペースを有効活用することができ、装置全体を小型化することができる。 For example, Patent Document 1 describes an interlocking member that rotates in conjunction with a throttle grip, a magnet attached to the interlocking member, and a magnet that can detect the rotation angle of the throttle grip by detecting a change in the magnetic force from the magnet. It has a sensor and a return spring that biases the throttle grip in the direction of returning to the initial position, and the interlocking member, the magnet, the magnetic sensor and the return spring are arranged in the handle pipe. . According to such a conventional throttle grip device, since the main components are arranged inside the handle pipe, the space inside the handle pipe can be effectively utilized, and the entire device can be made compact.

本実施形態に係る選択部材2は、上述の如く第1付勢手段S1の一端部及び第2付勢手段S2の一端部がそれぞれ取り付けられるとともに、スロットルグリップGが正回転したとき、第2付勢手段S2の付勢力を連動部材1に付与させずに第1付勢手段S1の付勢力を連動部材1に付与させ、スロットルグリップGが逆回転したとき、第1付勢手段S1の付勢力を連動部材1に付与させずに第2付勢手段S2の付勢力を連動部材1に付与し得るよう構成されている。 The selection member 2 according to the present embodiment has one end portion of the first urging means S1 and one end portion of the second urging means S2 respectively attached as described above, and when the throttle grip G rotates forward, the second attachment member 2 The biasing force of the first biasing means S1 is applied to the interlocking member 1 without applying the biasing force of the biasing means S2 to the interlocking member 1, and when the throttle grip G rotates in the reverse direction, the biasing force of the first biasing means S1 is applied. is applied to the interlocking member 1, and the urging force of the second urging means S2 can be applied to the interlocking member 1.

具体的には、連動部材1と選択部材2とは、図8、9で示すように組み付けられており、スロットルグリップGが初期位置(回転操作前の状態)にあるとき、連動部材1の当接部1cは、選択部材2における被当接部2aの間に位置している。そして、スロットルグリップGを正回転させると、連動部材1の当接部1cが被当接部2aと当接して押圧するので、選択部材2が同方向に回転することとなり、第1付勢手段S1による付勢力が連動部材1を介してスロットルグリップGに付与されることとなる。このとき、連動部材1及び選択部材2が共に回転するので、第2付勢手段S2による付勢力は付与されない。 Specifically, the interlocking member 1 and the selection member 2 are assembled as shown in FIGS. The contact portion 1c is located between the contacted portions 2a of the selection member 2. As shown in FIG. When the throttle grip G is rotated forward, the abutting portion 1c of the interlocking member 1 abuts and presses the abutted portion 2a, so that the selection member 2 rotates in the same direction as the first urging means. The biasing force of S1 is applied to the throttle grip G through the interlocking member 1. As shown in FIG. At this time, since the interlocking member 1 and the selection member 2 rotate together, no biasing force is applied by the second biasing means S2.

一方、スロットルグリップGを逆回転させると、連動部材1の当接部1cは、被当接部2aの間で移動するだけで当該被当接部2aと当接しないので、連動部材1の回転に伴う選択部材2の回転は行われない。また、選択部材2における被当接部2aの一方の縁部は、当該選択部材2が逆方向に回転しようとすると、先端部材9のストッパ部(不図示)と当接して回転が規制されるようになっている。これにより、連動部材1が回転しつつ選択部材2の回転が規制されるので、第2付勢手段S2による付勢力が連動部材1を介してスロットルグリップGに付与されることとなる。このとき、選択部材2は回転しないので、第1付勢手段S1による付勢力は付与されない。 On the other hand, when the throttle grip G is reversely rotated, the abutting portion 1c of the interlocking member 1 only moves between the abutted portions 2a and does not abut against the abutted portion 2a. The rotation of the selection member 2 associated with is not performed. One edge of the abutted portion 2a of the selection member 2 contacts a stopper portion (not shown) of the tip member 9 when the selection member 2 tries to rotate in the reverse direction, and the rotation is restricted. It's like As a result, the rotation of the selection member 2 is restricted while the interlocking member 1 rotates, so that the urging force of the second urging means S2 is applied to the throttle grip G via the interlocking member 1. At this time, since the selection member 2 does not rotate, no biasing force is applied by the first biasing means S1.

磁気センサ4(回転角度検出手段)は、連動部材1における回転軸の延長線上の位置に配設されたセンサから成り、ハンドルパイプH内に取り付けられるとともに、連動部材1に取り付けられた磁気部材Mから生じる磁気の変化を検出することにより、連動部材1及びスロットルグリップGの回転角度を検出可能とされている。具体的には、磁気センサ4は、磁気部材Mの磁場変化(磁束密度の変化)に応じた出力電圧を得ることができるもので、例えばホール効果を利用した磁気センサであるホール素子(具体的には、磁気部材Mの磁場(磁束密度)に比例した出力電圧を得ることができるリニアホールIC)等により構成されている。 The magnetic sensor 4 (rotational angle detection means) consists of a sensor arranged at a position on the extension line of the rotating shaft of the interlocking member 1, and is attached inside the handle pipe H, and the magnetic member M attached to the interlocking member 1. Rotation angles of the interlocking member 1 and the throttle grip G can be detected by detecting a change in magnetism generated from. Specifically, the magnetic sensor 4 can obtain an output voltage corresponding to a change in the magnetic field of the magnetic member M (change in magnetic flux density). is composed of a linear Hall IC capable of obtaining an output voltage proportional to the magnetic field (magnetic flux density) of the magnetic member M, or the like.

磁気部材Mは、磁気を生じた部材から成り、連動部材1に取り付けられて当該連動部材1と共に回転可能なものである。本実施形態に係る磁気部材Mは、保持部材8に保持されるとともに、当該保持部材8を介して連動部材1の取付部1dに取り付けられている。具体的には、磁気部材Mは、図27、28に示すように、少なくとも先端側が着磁された円筒状の樹脂部品から成り、軸部3bを挿通する挿通孔Mcが中央に形成されるとともに、基端側に第1被係止部Ma及び第2被係止部Mbが形成されている。なお、磁気部材Mは、本実施形態の如く着磁させた樹脂部品の他、永久磁石であってもよい。 The magnetic member M is made of a member that generates magnetism, and is attached to the interlocking member 1 so as to be rotatable together with the interlocking member 1 . The magnetic member M according to this embodiment is held by a holding member 8 and attached to the attachment portion 1 d of the interlocking member 1 via the holding member 8 . Specifically, as shown in FIGS. 27 and 28, the magnetic member M is made of a cylindrical resin part magnetized at least at the tip side, and has an insertion hole Mc in the center through which the shaft portion 3b is inserted. , a first engaged portion Ma and a second engaged portion Mb are formed on the base end side. The magnetic member M may be a permanent magnet as well as a magnetized resin component as in the present embodiment.

一方、保持部材8は、図29、30に示すように、磁気部材Mと略同一の径寸法とされた円筒状部品から成り、軸部3bを挿通する挿通孔8dが中央に形成されるとともに、連動部材1の取付部1dを嵌入させて連動部材1と係止可能な第1係止部8aが形成されている。また、保持部材8は、磁気部材Mの第2被係止部Mbを嵌入させて係止可能な係止凹部8bと、磁気部材Mの第1係止部Maに嵌入して係止可能な係止凸部8cとを有して構成されている。なお、これら係止凹部8b及び係止凸部8cは、磁気部材Mと係止可能な第2係止部を構成している。 On the other hand, as shown in FIGS. 29 and 30, the holding member 8 is made of a cylindrical part having substantially the same diameter as the magnetic member M, and has an insertion hole 8d in the center through which the shaft portion 3b is inserted. , a first locking portion 8a that can be locked with the interlocking member 1 by inserting the mounting portion 1d of the interlocking member 1 is formed. Further, the holding member 8 includes a locking recess 8b into which the second locked portion Mb of the magnetic member M can be fitted and locked, and a locking recess 8b into which the first locking portion Ma of the magnetic member M can be fitted and locked. It is configured to have a locking convex portion 8c. The locking concave portion 8b and the locking convex portion 8c constitute a second locking portion that can be locked with the magnetic member M. As shown in FIG.

そして、磁気部材Mの第1被係止部Maに保持部材8の係止凸部8cを嵌入させつつ保持部材8の係止凹部8bに磁気部材Mの第2被係止部Mbを嵌入させることにより、図31、32に示すように、保持部材8に磁気部材Mを保持させることができる。このように、磁気部材Mを保持した保持部材8の第1係止部8aに対して、連動部材1の取付部1dを嵌入させることにより、図33、34に示すように、連動部材1、保持部材8及び磁気部材MをハンドルパイプH内における軸方向に組み付けることができ、連動部材1の回転に伴って、保持部材8及び磁気部材Mが一体として回転可能とされている。また、収容部材3の軸部3bは、連動部材1の挿通孔1b、保持部材8の挿通孔8d及び磁気部材Mの挿通孔Mcにそれぞれ挿通して組み付けられるので、連動部材1の回転に伴って、連動部材1、保持部材8及び磁気部材Mが一体として軸部3bを中心として回転可能とされている。 Then, the second locked portion Mb of the magnetic member M is fitted into the locking concave portion 8b of the holding member 8 while the locking convex portion 8c of the holding member 8 is fitted into the first locked portion Ma of the magnetic member M. Thereby, as shown in FIGS. 31 and 32, the holding member 8 can hold the magnetic member M. FIG. By fitting the mounting portion 1d of the interlocking member 1 into the first locking portion 8a of the holding member 8 holding the magnetic member M, as shown in FIGS. The holding member 8 and the magnetic member M can be assembled in the axial direction in the handle pipe H, and the holding member 8 and the magnetic member M can be rotated together as the interlocking member 1 rotates. Further, since the shaft portion 3b of the housing member 3 is assembled by being inserted into the insertion hole 1b of the interlocking member 1, the insertion hole 8d of the holding member 8, and the insertion hole Mc of the magnetic member M, the shaft portion 3b is assembled as the interlocking member 1 rotates. Thus, the interlocking member 1, the holding member 8 and the magnetic member M are integrally rotatable about the shaft portion 3b.

しかして、スロットルグリップGが正回転するのに伴って連動部材1が同方向に回転すると、保持部材8を介して当該連動部材1に取り付けられた磁気部材Mも同方向に回転する。これにより、その回転角度によって磁場が変化するので、当該回転角度に応じた磁気センサ4の出力電圧を得ることができ、当該出力電圧に基づき連動部材1の回転角度(即ち、スロットルグリップGの回転角度)を検出することが可能とされている。このように検出されたスロットルグリップGの回転角度は、二輪車に搭載されたECU(エンジン・コントロール・ユニット)に対して電気信号として送信され、送信されたスロットルグリップGの回転角度に応じて車両のエンジン(駆動源)が制御され得るようになっている。 Thus, when the interlocking member 1 rotates in the same direction as the throttle grip G rotates forward, the magnetic member M attached to the interlocking member 1 via the holding member 8 also rotates in the same direction. As a result, the magnetic field changes depending on the rotation angle, so that the output voltage of the magnetic sensor 4 corresponding to the rotation angle can be obtained. angle) can be detected. The rotation angle of the throttle grip G thus detected is transmitted as an electric signal to an ECU (engine control unit) mounted on the motorcycle, and the vehicle is controlled according to the transmitted rotation angle of the throttle grip G. The engine (driving source) can be controlled.

一方、スロットルグリップGが逆回転するのに伴って連動部材1が同方向に回転すると、保持部材8を介して当該連動部材1に取り付けられた磁気部材Mも同方向に回転する。これにより、その回転角度によって磁場が変化するので、当該回転角度に応じた磁気センサ4の出力電圧を得ることができ、スロットルグリップGの逆回転を検出することができる。このように、スロットルグリップGの逆回転が検出されると、二輪車が具備する所定の機能を作動又は非作動とすることができるようになっている。本実施形態においては、走行速度を一定に保持する定車速保持装置(オートクルーズ装置)を備えた二輪車に適用されており、スロットルグリップGを逆回転(初期位置からスロットルを全開させる正回転の方向とは逆方向の回転操作)させると、当該定車速の保持制御を停止(キャンセル)させ得るよう構成されている。 On the other hand, when the interlocking member 1 rotates in the same direction as the throttle grip G rotates in the reverse direction, the magnetic member M attached to the interlocking member 1 via the holding member 8 also rotates in the same direction. As a result, the magnetic field changes according to the rotation angle, so that the output voltage of the magnetic sensor 4 corresponding to the rotation angle can be obtained, and the reverse rotation of the throttle grip G can be detected. In this way, when reverse rotation of the throttle grip G is detected, a predetermined function of the two-wheeled vehicle can be activated or deactivated. This embodiment is applied to a two-wheeled vehicle equipped with a constant vehicle speed holding device (auto-cruise device) that holds the running speed constant. ), the constant vehicle speed holding control can be stopped (cancelled).

Furthermore, as shown in FIG. 18, a plurality of wirings h (electrical cords) capable of transmitting the detection signal of the magnetic sensor 4 to the outside are connected to the second portion 5b of the flexible substrate 5 by soldering or the like. The extension surface 6ba of the base member 6 is integrally formed with holding portions 6c and 6d capable of guiding and holding the wiring h. That is, each of the holding portions 6c and 6d is formed of a pair of protrusions separated by a predetermined distance from the extended surface 6ba of the base member 6, and the wiring h is positioned and held at the separated portions.

しかして、収容部材3内に台部材6がスナップフィットにて固定されると、図20、21に示すように、フレキシブル基板5の第1部位5aに形成された磁気センサ4が収容部材3の底部3e(底面)と対向して配置されるとともに、軸方向に亘って第2部位5b及び第3部位5cが配置されることとなる。しかして、収容部材3の収容空間α1がハンドルパイプHの軸方向に細長い空間であっても、磁気センサ4及びフレキシブル基板5を効率よく配設することができる。 20 and 21, the magnetic sensor 4 formed on the first portion 5a of the flexible substrate 5 is attached to the housing member 3. The second portion 5b and the third portion 5c are arranged along the axial direction so as to face the bottom portion 3e (bottom surface). Therefore, even if the accommodation space α1 of the accommodation member 3 is elongated in the axial direction of the handle pipe H, the magnetic sensor 4 and the flexible substrate 5 can be arranged efficiently.
