Description

本発明は、車両等に適用されるアクセルペダル装置に関し、特に、アクセルペダルを休止位置に戻す複数の戻しバネを備えたアクセルペダル装置に関する。 The present invention relates to an accelerator pedal device applied to a vehicle or the like, and more particularly to an accelerator pedal device provided with a plurality of return springs for returning the accelerator pedal to a resting position.

従来のアクセルペダル装置としては、アクセルペダルに連結され支点を中心として回動するアクセルアームと、支点からの離隔距離がそれぞれ異なる位置においてアクセルアームに掛止された引張り型の二つのコイルバネを備えたアクセル機構が知られている（例えば、特許文献１）。 The conventional accelerator pedal device includes an accelerator arm that is connected to the accelerator pedal and rotates around a fulcrum, and two tension-type coil springs that are fastened to the accelerator arm at different distances from the fulcrum. The accelerator mechanism is known (for example, Patent Document 1).

この装置において、アクセルペダルの踏込みが小さい領域では、一方のコイルバネの張力が主として作用し、アクセルペダルの踏込みが大きい領域では、両方のコイルバネの張力が作用するものである。すなわち、踏力特性としては、踏込みが小さい領域で踏力が小さく、踏込みが大きい領域で踏力が大きくなるものの、二つのコイルバネの合成付勢力が常に作用する一つの踏力特性が得られるものである。
したがって、非力な運転者にとっては、特に踏込み量が大きい領域において、アクセルペダルが重く、操作性が悪いと感じる虞がある。 In this device, the tension of one coil spring mainly acts in the region where the depression of the accelerator pedal is small, and the tension of both coil springs acts in the region where the depression of the accelerator pedal is large. That is, as the pedaling force characteristic, although the pedaling force is small in the region where the depression is small and the pedaling force is large in the region where the depression is large, one pedaling force characteristic in which the combined urging force of the two coil springs always acts can be obtained.
Therefore, a weak driver may feel that the accelerator pedal is heavy and the operability is poor, especially in a region where the amount of depression is large.

また、他のアクセルペダル装置としては、アクセルペダルを有するペダルアームと、ペダルアームを軸部回りに回動自在に支持するハウジングと、ペダルアームの上端部に付勢力を及ぼすべく入れ子状に配置された圧縮型の二つのコイルバネを備えたアクセル装置が知られている（例えば、特許文献２）。 Further, as other accelerator pedal devices, a pedal arm having an accelerator pedal, a housing that rotatably supports the pedal arm around the shaft portion, and a nested arrangement for exerting a urging force on the upper end portion of the pedal arm. An accelerator device including two compression type coil springs is known (for example, Patent Document 2).

この装置においても、前述の従来例のように、二つのコイルバネの合成付勢力が常に作用する一つの踏力特性が得られるものである。
したがって、非力な運転者にとっては、特に踏込み量が大きい領域において、アクセルペダルが重く、操作性が悪いと感じる虞がある。 Also in this device, as in the above-mentioned conventional example, one pedaling force characteristic in which the combined urging force of the two coil springs always acts can be obtained.
Therefore, a weak driver may feel that the accelerator pedal is heavy and the operability is poor, especially in a region where the amount of depression is large.

It is equipped with a sub-return spring that generates an urging force that returns the arm to the resting position, and a switching unit that selectively switches between an acting state in which the sub-return spring exerts an urging force on the pedal arm and a non-acting state in which the sub-return spring exerts no urging force. , The switching unit is a movable member that can move following the rotation of the pedal arm while the first end of the secondary return spring is engaged, and the movement of the movable member is restricted in the working state and in the non-working state. It is configured to include an operation member that can be operated to allow the movement of the movable member.

A configuration may be adopted that includes a restricting portion that engages with the engaging portion to regulate the rotation of the rotating member.

上記アクセルペダル装置において、係合部は、ハウジング内に配置され、操作部材は、ハウジングの外側から内側に貫通して往復動自在に保持され、係合部から離脱して回動部材の回動を許容し、係合部と係合して回動部材の回動を規制する規制部を含む、構成を採用してもよい。 In the accelerator pedal device, the engaging portion is arranged inside the housing, and the operating member penetrates from the outside to the inside of the housing and is held reciprocally, and is separated from the engaging portion to rotate the rotating member.

上記アクセルペダル装置において、主戻しバネは、円筒部の近傍において上側アーム寄りに配置されている、構成を採用してもよい。 In the accelerator pedal device, the main return spring may be arranged near the upper arm in the vicinity of the cylindrical portion.

上記アクセルペダル装置において、アクセルペダルの踏込み操作及び戻し操作における踏力にヒステリシスを発生するヒステリシス発生機構をさらに含む、構成を採用いてもよい。 In the accelerator pedal device, a configuration may be adopted further including a hysteresis generation mechanism that generates a hysteresis in the pedaling force in the depression operation and the return operation of the accelerator pedal.

上記アクセルペダル装置において、ヒステリシス発生機構は、ハウジングの内壁を摺動するスライダと、スライダを押し戻しつつハウジングに押し付ける付勢力を及ぼす付勢バネを含み、スライダは、ペダルアームの上端部と係合するように配置されている、構成を採用してもよい。 In the accelerator pedal device, the hysteresis generating mechanism includes a slider that slides on the inner wall of the housing and an urging spring that exerts an urging force that pushes the slider back against the housing, and the slider engages with the upper end portion of the pedal arm. The configuration may be adopted so as to be arranged.

上記構成をなすアクセルペダル装置によれば、構造の簡素化、小型化等を達成しつつ、安価で、簡単な操作により軽重の二種類の踏力特性のいずれかに選択的に切り換えることのできるアクセルペダル装置を得ることができる。 According to the accelerator pedal device having the above configuration, the accelerator can be selectively switched to one of two types of light and heavy pedaling force characteristics by simple operation at low cost while achieving simplification and miniaturization of the structure. You can get a pedal device.

主戻しバネ３０は、バネ鋼等により形成された伸縮コイルバネであり、第１端部３１が第１ハウジング１１のバネ受け部１１ｈに当接しかつ第２端部３２がペダルアーム２０のバネ受け部２９に当接するように所定の圧縮代に圧縮されて配置され、常にペダルアーム２０を休止位置に戻す付勢力を及ぼす。
このように、主戻しバネ３０は、ペダルアーム２０に直接係合して常にペダルアーム２０を休止位置に戻す付勢力を及ぼすため、ヒステリシス発生機構８０がスティックして停止したような作動不良の状態が生じ又副戻しバネ４０が非作用の状態であっても、ペダルアーム２０は、主戻しバネ３０の付勢力により休止位置へ確実に戻されて、安全性が保証される。 The main return spring 30 is a telescopic coil spring formed of spring steel or the like, and the first end portion 31 abuts on the spring receiving portion 11h of the first housing 11 and the second end portion 32 is the spring receiving portion of the pedal arm 20.

The pedal arm 20 is surely returned to the resting position by the urging force of the main return spring 30 even when the sub-return spring 40 is inactive, and the safety is guaranteed.

副戻しバネ４０は、バネ鋼等により形成された捩りコイルバネであり、図３及び図６に示すように、コイル部４１、第１端部４２、第２端部４３を備えている。

It is hooked in the hooking groove 23 as a part of the cylindrical portion 21 of the arm 20.
Then, the sub-return spring 40 exerts an urging force to return the pedal arm 20 to the resting position when the switching unit U selects the working state, and when the switching unit U selects the non-working state, the pedal arm 20 is pressed. The rotating member 50 is rotated by following the rotation of the pedal arm 10 without exerting the urging force to return to the rest position.

回動部材５０は、樹脂材料を用いて形成され、図６及び図７に示すように、円盤状の鍔部５１、軸部２４が嵌合される嵌合穴５２、副戻しバネ４０の第１端部４２が掛止される掛止部５３、当接部５４、操作部材６０の規制部６２の係合により回動が規制される係合部５５を備えている。 The rotating member 50 is formed by using a resin material, and as shown in FIGS. 6 and 7, a disk-shaped flange portion 51, a fitting hole 52 into which a shaft portion 24 is fitted, and a second return spring 40 are used.

当接部５４は、副戻しバネ４０がペダルアーム２０に対して付勢力を及ぼす作用状態においてペダルアーム２０が踏み込まれると受け部２５から離脱し、副戻しバネ４０がペダルアーム２０に対して付勢力を及ぼさない非作用状態において受け部２５に当接する。
係合部５５は、略矩形断をなす所定幅の二面幅部として形成され、第１ハウジング１１の開口部１１ｄを通して外側に配置され、操作部材６０の規制部６２と係合すると、回動部材５０の回動が規制され、操作部材６０の規制部６２から離脱すると、回動部材５０の回動が許容されるべく機能する。 The flange portion 51 is arranged so as to be sandwiched between the wall surface around the opening 11d of the first housing 11 and the wall surface of the region of the cylindrical portion 21 of the pedal arm 20.
The contact portion 54 is separated from the receiving portion 25 when the pedal arm 20 is stepped on while the sub-return spring 40 exerts a urging force on the pedal arm 20, and the sub-return spring 40 is attached to the pedal arm 20. It comes into contact with the receiving portion 25 in a non-acting state where no force is exerted.
The engaging portion 55 is formed as a two-sided width portion having a predetermined width forming a substantially rectangular cut, is arranged outside through the opening 11d of the first housing 11, and rotates when engaged with the restricting portion 62 of the operating member 60. When the rotation of the member 50 is restricted and the operating member 60 is separated from the regulating portion 62, the rotation of the rotating member 50 functions to be permitted.

そして、回動部材５０は、ペダルアーム２０の軸部２４が嵌合穴５２に嵌合されると共に環状溝２２に収容された副戻しバネ４０の第１端部４２が掛止部５３に掛止されて、係合部５５が開口部１１ｄを通して外部に突出するように、第１ハウジング１１とペダルアーム２０とに挟まれる領域に配置され、軸線Ｓ回りに回動自在に支持される。 Then, in the rotating member 50, the shaft portion 24 of the pedal arm 20 is fitted into the fitting hole 52, and the first end portion 42 of the auxiliary return spring 40 housed in the annular groove 22 is hooked on the hooking portion 53. It is stopped and arranged in a region sandwiched between the first housing 11 and the pedal arm 20 so that the engaging portion 55 projects outward through the opening 11d, and is rotatably supported around the axis S.

操作部材６０は、樹脂材料等を用いて略矩形の板状に形成され、図９に示すように、操作部６１、規制部６２、位置決め溝６３を備えている。
操作部６１は、図２に示すように、車両の運転者等が指で掴めるように半円柱状に形成され、外部に露出して配置される。
規制部６２は、略Ｕ字状の切欠きを画定し、回動部材５０の係合部５５の二面幅部が嵌合する切欠き幅に形成されている。
位置決め溝６３は、Ｖ字状の断面をなすと共に軸線Ｓに平行な直線溝として形成され、操作部材６０の往復動方向において離隔して配置された第１位置決め溝６３ａ及び第２位置決め溝６３ｂを備えている。 The operation member 60 is formed in a substantially rectangular plate shape using a resin material or the like, and includes an operation unit 61, a regulation unit 62, and a positioning groove 63 as shown in FIG.
As shown in FIG. 2, the operation unit 61 is formed in a semi-cylindrical shape so that a driver or the like of a vehicle can grasp it with a finger, and is arranged so as to be exposed to the outside.
The restricting portion 62 defines a substantially U-shaped notch, and is formed to have a notch width into which the width across flats of the engaging portion 55 of the rotating member 50 fits.
The positioning groove 63 has a V-shaped cross section and is formed as a straight groove parallel to the axis S. I have.

そして、図９に示すように、操作部材６０は、第１位置決め溝６３ａが保持部１１ｑの位置決め突起１１ｑ２と係合したとき、規制部６２が係合部５５に係合して、回動部材５０の回動を規制する位置に位置決めされる。これにより、副戻しバネ４０がペダルアーム２０に対して付勢力を及ぼす作用状態が設定される。
一方、操作部材６０は、第２位置決め溝６３ｂが保持部１１ｑの位置決め突起１１ｑ２と係合したとき、規制部６２が係合部５５から離脱して、回動部材５０の回動を許容する位置に位置決めされる。これにより、副戻しバネ４０がペダルアーム２０に対して付勢力を及ぼさない非作用状態が設定される。 Then, as shown in FIG. 9, when the first positioning groove 63a engages with the positioning projection 11q 2 of the holding portion 11q, the regulating portion 62 engages with the engaging portion 55 and rotates. It is positioned at a position that restricts the rotation of the member 50. As a result, the action state in which the sub-return spring 40 exerts a urging force on the pedal arm 20 is set.
On the other hand, when the second positioning groove 63b engages with the positioning projection 11q 2 of the holding portion 11, the operating member 60 disengages the regulating portion 62 from the engaging portion 55 and allows the rotating member 50 to rotate. Positioned in position. As a result, the non-acting state in which the sub-return spring 40 does not exert a urging force on the pedal arm 20 is set.

上記構成をなす回動部材５０及び操作部材６０は、副戻しバネ４０がペダルアーム２０に対して付勢力を及ぼす作用状態と、当該付勢力を及ぼさない非作用状態とを、手動操作により選択的に切り換える切換ユニットＵを構成するものである。
すなわち、操作部材６０が押し込まれると、規制部６２が係合部５５に係合して回動部材５０の回動を規制し、副戻しバネ４０がペダルアーム２０に対して付勢力を及ぼす作用状態となる。これにより、回動部材５０は、図１０及び図１２に示すように、ペダルアーム２０が休止位置から最大踏込み位置まで踏み込まれても、休止位置に対応する位置に停止する。それ故に、副戻しバネ４０は踏込み量に応じた付勢力をペダルアーム２０に及ぼす。
一方、操作部材６０が引き出されると、規制部６２が係合部５５から離脱して回動部材５０の回動を許容し、副戻しバネ４０がペダルアーム２０に対して付勢力を及ぼさない非作用状態となる。これにより、回動部材５０は、図１０及び図１１に示すように、ペダルアーム２０が休止位置から最大踏込み位置まで踏み込まれると、ペダルアーム２０に追従して回転する。それ故に、副戻しバネ４０は回動部材５０と一緒に回転して付勢力をペダルアーム２０に及ぼさない。 The rotating member 50 and the operating member 60 having the above configuration selectively select the acting state in which the secondary return spring 40 exerts an urging force on the pedal arm 20 and the non-acting state in which the urging force is not exerted. It constitutes a switching unit U for switching to.
That is, when the operating member 60 is pushed in, the restricting portion 62 engages with the engaging portion 55 to restrict the rotation of the rotating member 50, and the auxiliary return spring 40 exerts an urging force on the pedal arm 20. It becomes a state. As a result, as shown in FIGS. 10 and 12, the rotating member 50 stops at the position corresponding to the resting position even if the pedal arm 20 is stepped on from the resting position to the maximum stepping position. Therefore, the sub-return spring 40 exerts an urging force on the pedal arm 20 according to the amount of depression.
On the other hand, when the operating member 60 is pulled out, the regulating portion 62 disengages from the engaging portion 55 to allow the rotating member 50 to rotate, and the sub-return spring 40 does not exert an urging force on the pedal arm 20. It becomes an working state. As a result, as shown in FIGS. 10 and 11, when the pedal arm 20 is stepped on from the resting position to the maximum stepping position, the rotating member 50 rotates following the pedal arm 20. Therefore, the secondary return spring 40 rotates together with the rotating member 50 and does not exert an urging force on the pedal arm 20.

位置センサ７０は、図８に示すように、ペダルアーム２０の軸線Ｓの周りの領域に配置された非接触式の磁気式センサであり、環状のアマチャ７１、一対の永久磁石７２、二つのステータ７３、二つのホール素子７４を備えている。
アマチャ７１は、磁性材料により環状に形成されて、ペダルアーム２０の凹部２６に埋設されている。

二つのホール素子７４は、二つのステータ７３の間に配置されて第２ハウジング１２の埋設部１２ｑに埋設されている。 As shown in FIG. 8, the position sensor 70 is a non-contact magnetic sensor arranged in a region around the axis S of the pedal arm 20, and is an annular armature 71, a pair of permanent magnets 72, and two stators. 73, two Hall elements 74 are provided.
The Amacha 71 is formed in an annular shape by a magnetic material and is embedded in a recess 26 of the pedal arm 20.
The pair of permanent magnets 72 are formed in an arc shape and are coupled to the inner peripheral surface of the Amacha 71 so as to be exposed on the inner peripheral surface 26a of the recess 26.
The two stators 73 are formed of a magnetic material and are embedded in the embedded portion 12q of the second housing 12.
The two Hall elements 74 are arranged between the two stators 73 and embedded in the embedded portion 12q of the second housing 12.

また、回路基板ＣＢが、第２ハウジング１２の収容部１２ｒに配置されて、封止樹脂材Ｇにより封止されている。
回路基板ＣＢは、ホール素子７４を電気的に接続する回路を備えると共に、種々の電子部品を実装するものである。
そして、位置センサ７０は、ペダルアーム２０が回動することにより生じる磁束密度の変化をホール素子７４で検出して電圧信号として出力する。この出力信号は、コネクタ１２ｓに接続された検出器（不図示）により、ペダルアーム２０の角度位置の情報として検出される。 Further, the circuit board CB is arranged in the accommodating portion 12r of the second housing 12 and is sealed by the sealing resin material G.
The circuit board CB includes a circuit for electrically connecting the Hall element 74 and mounts various electronic components.
Then, the position sensor 70 detects the change in the magnetic flux density caused by the rotation of the pedal arm 20 by the Hall element 74 and outputs it as a voltage signal. This output signal is detected as information on the angular position of the pedal arm 20 by a detector (not shown) connected to the connector 12s.

ヒステリシス発生機構８０は、図３及び図５に示すように、含油ポリアセタール等の高摺動性樹脂材料により形成された第１スライダ８１及び第２スライダ８２、バネ鋼等により形成された付勢バネ８３を備えている。
第１スライダ８１は、第１ハウジング１１の下側の摺動面１１ｆに摺動自在に接触する接触面８１ａ、第２スライダ８２の傾斜面８２ｂと接触する傾斜面８１ｂ、上側アーム部２７の上端部２７ｂが離脱可能に係合し得る係合面８１ｃを有する。
第２スライダ８２は、第１ハウジング１１の上側の摺動面１１ｅに摺動自在に接触する接触面８２ａ、第１スライダ８１の傾斜面８１ｂと接触する傾斜面８２ｂ、付勢バネ８３の第２端部８３ｂを受ける受け面８２ｃを有する。
付勢バネ８３は、伸縮コイルバネであり、第１端部８３ａが第１ハウジング１１のバネ受け部１１ｇに当接しかつ第２端部８３ｂが第２スライダ８２の受け面８２ｃに当接して圧縮された状態で配置される。 As shown in FIGS. 3 and 5, the hysteresis generation mechanism 80 includes a first slider 81 and a second slider 82 formed of a highly slidable resin material such as oil-impregnated polyacetal, and an urging spring formed of spring steel or the like. It is equipped with 83.
The first slider 81 has a contact surface 81a that slidably contacts the lower sliding surface 11f of the first housing 11, an inclined surface 81b that contacts the inclined surface 82b of the second slider 82, and the upper end of the upper arm portion 27. The portion 27b has an engaging surface 81c to which the portion 27b can be disengaged and engaged.
The second slider 82 has a contact surface 82a that slidably contacts the upper sliding surface 11e of the first housing 11, an inclined surface 82b that comes into contact with the inclined surface 81b of the first slider 81, and a second urging spring 83. It has a receiving surface 82c that receives the end portion 83b.
The urging spring 83 is a telescopic coil spring, and the first end portion 83a abuts on the spring receiving portion 11g of the first housing 11 and the second end portion 83b abuts on the receiving surface 82c of the second slider 82 and is compressed. It is placed in a state of being.

そして、付勢バネ８３は、第２スライダ８２の傾斜面８２ｂを第１スライダ８１の傾斜面８１ｂに押し付けて、第１スライダ８１及び第２スライダ８２を摺動面１１ｅ，１１ｆに向けて押し付けるようなくさび作用を及ぼし、又、第１スライダ８１及び第２スライダ８２を介してペダルアーム２０を休止位置に戻す付勢力を及ぼす。 Then, the urging spring 83 presses the inclined surface 82b of the second slider 82 against the inclined surface 81b of the first slider 81, and presses the first slider 81 and the second slider 82 toward the sliding surfaces 11e and 11f. It exerts a rusting action and also exerts a urging force to return the pedal arm 20 to the resting position via the first slider 81 and the second slider 82.

ここで、ヒステリシス発生機構８０が発生するヒステリシス特性について説明する。
先ず、ペダルアーム２０が、休止位置から最大踏込み位置に向けて踏み込まれる場合は、上端部２７ｂが付勢バネ８３の付勢力に抗して第１スライダ８１を図５中の左向きに押圧する。
この踏込み操作のとき、付勢バネ８３が及ぼす付勢力により、第１スライダ８１及び第２スライダ８２が互いにくさび作用を及ぼし、ハウジング１０に対して摩擦力（摺動抵抗）が生じる。踏込み操作時の摩擦力は、踏込み操作と対抗する向きに作用すると共に付勢バネ８３の圧縮量の増加に伴って増加する。
したがって、踏込み操作時の摩擦力と踏込み操作に応じて増加する付勢バネ８３の付勢力との合力により、踏込み時の踏力は、図１３のヒステリシスをなす踏力線ＮＬにおいて、上側の踏力線ＤＮＬとして示され、踏込み量（アクセルペダルの開度）の増加に伴って直線的に増加する。 Here, the hysteresis characteristic in which the hysteresis generation mechanism 80 is generated will be described.
First, when the pedal arm 20 is stepped on from the resting position toward the maximum stepping position, the upper end portion 27b presses the first slider 81 to the left in FIG. 5 against the urging force of the urging spring 83.
During this stepping operation, the urging force exerted by the urging spring 83 causes the first slider 81 and the second slider 82 to wedge each other, and a frictional force (sliding resistance) is generated with respect to the housing 10. The frictional force during the stepping operation acts in a direction opposite to the stepping operation and increases with an increase in the amount of compression of the urging spring 83.
Therefore, due to the resultant force of the frictional force during the stepping operation and the urging force of the urging spring 83 increasing in response to the stepping operation, the pedaling force at the time of stepping is the upper pedaling force line DNL in the pedaling force line NL forming the hysteresis of FIG. It is shown as, and increases linearly with an increase in the amount of depression (opening of the accelerator pedal).

一方、ペダルアーム２０が、休止位置に向けて戻される場合は、第１スライダ８１及び第２スライダ８２は、付勢バネ８３の付勢力により上側アーム部２７に追従して図５中の右向きに移動する。
この戻し操作のときも、付勢バネ８３が及ぼす付勢力により、第１スライダ８１及び第２スライダ８２が互いにくさび作用を及ぼし、ハウジング１０に対して摩擦力（摺動抵抗）が生じる。戻し操作時の摩擦力は、踏込み操作の場合と逆向きに作用すると共に付勢バネ８３の圧縮量の減少に伴って減少する。
したがって、逆向きに作用する戻し操作時の摩擦力と戻し操作に応じて減少する付勢バネ８３の付勢力との合力により、戻し時の踏力は、図１３のヒステリシスをなす踏力線ＮＬにおいて、下側の踏力線ＲＮＬとして示され、踏込み量（アクセルペダルの開度）の減少に伴って直線的に減少する。
ここで、戻り動作の際の踏力は、踏込み操作の際の踏力よりも小さくなるため、図１３中の踏力線ＤＮＬ，ＲＮＬで示すように、踏込み操作から戻し操作までの全体において、踏力にヒステリシスが発生する。 On the other hand, when the pedal arm 20 is returned toward the resting position, the first slider 81 and the second slider 82 follow the upper arm portion 27 by the urging force of the urging spring 83 and turn to the right in FIG. Moving.
Even during this return operation, the urging force exerted by the urging spring 83 causes the first slider 81 and the second slider 82 to wedge each other, and a frictional force (sliding resistance) is generated with respect to the housing 10. The frictional force during the return operation acts in the opposite direction to that during the stepping operation, and decreases as the amount of compression of the urging spring 83 decreases.
Therefore, due to the resultant force of the frictional force during the return operation acting in the opposite direction and the urging force of the urging spring 83 that decreases in response to the return operation, the pedaling force at the time of returning is the pedaling force line NL forming the hysteresis of FIG. It is shown as a lower pedaling force line RNL, and decreases linearly as the depression amount (opening of the accelerator pedal) decreases.
Here, since the treading force during the return operation is smaller than the treading force during the stepping operation, as shown by the treading force lines DNL and RNL in FIG. Occurs.

次に、アクセルペダル装置及び切換ユニットＵの動作を、図１１ないし図１３を参照しつつ説明する。
先ず、運転者は、運転に先立って、アクセルペダル２８ａを踏込み、アクセルペダル２８ａの反力が重いと感じれば「軽いモード」を選択し又は軽いと感じれば「重いモード」を選択するべく、切換ユニットＵの操作部材６０を手動により適宜操作する。 Next, the operation of the accelerator pedal device and the switching unit U will be described with reference to FIGS. 11 to 13.
First, the driver depresses the accelerator pedal 28a prior to driving, and switches to select the "light mode" if the reaction force of the accelerator pedal 28a is felt to be heavy, or to select the "heavy mode" if the reaction force is felt to be light. The operation member 60 of the unit U is manually operated as appropriate.

ここで、「重いモード」を選択する場合、操作部材６０を押し込んで規制部６２を回動部材５０の係合部５５に係合させる。これにより、回動部材５０は回動が規制されて休止位置に対応する位置に保持される。これにより、副戻しバネ４０は、ペダルアーム２０に対して付勢力を及ぼす作用状態に設定される。 Here, when the "heavy mode" is selected, the operating member 60 is pushed in to engage the regulating portion 62 with the engaging portion 55 of the rotating member 50. As a result, the rotating member 50 is restricted from rotating and is held at a position corresponding to the resting position. As a result, the sub-return spring 40 is set to an action state in which a urging force is applied to the pedal arm 20.

そして、運転者がアクセルペダル２８ａを休止位置から踏み込むと、図１２に示すように、回動部材５０の回動が規制された状態で、ペダルアーム２０のみが、主戻しバネ３０及び副戻しバネ４０の付勢力に抗して反時計回りに回転し、ヒステリシス発生機構８０が発生する抵抗荷重は増加しつつ、図１３中の実線で示す上側の踏力線ＤＮＬに沿って踏力が増加する。そして、ペダルアーム２０は、最大踏込み位置まで回転し、当接部２８ｂが全開ストッパ１１ｊに当接して停止する。 Then, when the driver depresses the accelerator pedal 28a from the resting position, as shown in FIG. 12, only the pedal arm 20 has the main return spring 30 and the sub-return spring in a state where the rotation of the rotating member 50 is restricted. It rotates counterclockwise against the urging force of 40, and while the resistance load generated by the hysteresis generation mechanism 80 increases, the pedaling force increases along the upper pedaling force line DNL shown by the solid line in FIG. Then, the pedal arm 20 rotates to the maximum stepping position, and the contact portion 28b comes into contact with the fully open stopper 11j and stops.

一方、運転者が踏力を緩めると、アクセルペダル２８ａは、踏み込み時の抵抗荷重よりも小さい抵抗荷重を運転者に及ぼしながら、ペダルアーム２０は、主戻しバネ３０及び副戻しバネ４０の付勢力により休止位置に向けて回転し、ヒステリシス発生機構８０が発生する抵抗荷重は減少しつつ、図１３中の実線で示す上側の踏力線ＲＮＬに沿って踏力が減少する。そして、ペダルアーム２０は、当接部２７ａが休止ストッパ１１ｉに当接して休止位置に停止する。 On the other hand, when the driver relaxes the pedaling force, the accelerator pedal 28a exerts a resistance load smaller than the resistance load at the time of depression on the driver, while the pedal arm 20 is subjected to the urging force of the main return spring 30 and the sub-return spring 40. Rotating toward the rest position, the resistance load generated by the hysteresis generation mechanism 80 decreases, and the pedaling force decreases along the upper pedaling force line RNL shown by the solid line in FIG. Then, in the pedal arm 20, the contact portion 27a comes into contact with the rest stopper 11i and stops at the rest position.

尚、運転者がアクセルペダル２８ａを戻す際に、ヒステリシス発生機構８０がスティック等によりハウジング１０の内壁に固着して戻らない場合であっても、主戻しバネ３０及び副戻しバネ４０の付勢力により、上端部２７ｂが第１スライダ８１から離脱して、ペダルアーム２０は確実に休止位置に戻る。
したがって、位置センサ７０は、ペダルアーム２０が休止位置に戻ったことを検出するため、運転者の戻し動作と連動して所望の制御を行うことができる。 Even if the hysteresis generation mechanism 80 is stuck to the inner wall of the housing 10 by a stick or the like and does not return when the driver returns the accelerator pedal 28a, the urging force of the main return spring 30 and the sub return spring 40 causes the driver to return. , The upper end portion 27b is separated from the first slider 81, and the pedal arm 20 surely returns to the rest position.
Therefore, since the position sensor 70 detects that the pedal arm 20 has returned to the resting position, it is possible to perform desired control in conjunction with the return operation of the driver.

一方、運転者が「軽いモード」を選択する場合、操作部材６０を引き出して規制部６２を回動部材５０の係合部５５から離脱させる。これにより、回動部材５０は回動が許容された状態となる。これにより、副戻しバネ４０は、ペダルアーム２０に対して付勢力を及ぼさない非作用状態に設定される。 On the other hand, when the driver selects the "light mode", the operating member 60 is pulled out to disengage the regulating portion 62 from the engaging portion 55 of the rotating member 50. As a result, the rotating member 50 is in a state where rotation is permitted. As a result, the sub-return spring 40 is set in a non-acting state in which no urging force is exerted on the pedal arm 20.

そして、運転者がアクセルペダル２８ａを休止位置から踏み込むと、図１１に示すように、回動部材５０はペダルアーム２０の回転に追従して回転する状態となり、ペダルアーム２０が、主戻しバネ３０の付勢力に抗して反時計回りに回転し、ヒステリシス発生機構８０が発生する抵抗荷重は増加しつつ、図１３中の一点鎖線で示す下側の踏力線ＤＮＬに沿って踏力が増加する。そして、ペダルアーム２０は、最大踏込み位置まで回転し、当接部２８ｂが全開ストッパ１１ｊに当接して停止する。 Then, when the driver depresses the accelerator pedal 28a from the resting position, as shown in FIG. 11, the rotating member 50 is in a state of rotating following the rotation of the pedal arm 20, and the pedal arm 20 is in a state of rotating following the rotation of the pedal arm 20. Rotates counterclockwise against the urging force of the above, and while the resistance load generated by the hysteresis generation mechanism 80 increases, the pedaling force increases along the lower pedaling force line DNL shown by the alternate long and short dash line in FIG. Then, the pedal arm 20 rotates to the maximum stepping position, and the contact portion 28b comes into contact with the fully open stopper 11j and stops.

一方、運転者が踏力を緩めると、アクセルペダル２８ａは、踏み込み時の抵抗荷重よりも小さい抵抗荷重を運転者に及ぼしながら、ペダルアーム２０は、主戻しバネ３０の付勢力により休止位置に向けて回転し、ヒステリシス発生機構８０が発生する抵抗荷重が減少しつつ、図１３中の一点鎖線で示す下側の踏力線ＲＮＬに沿って踏力が減少する。そして、ペダルアーム２０は、当接部２７ａが休止ストッパ１１ｉに当接して休止位置に停止する。 On the other hand, when the driver relaxes the pedaling force, the accelerator pedal 28a exerts a resistance load smaller than the resistance load at the time of depression on the driver, while the pedal arm 20 is directed toward the resting position by the urging force of the main return spring 30. While rotating and the resistance load generated by the hysteresis generation mechanism 80 is reduced, the pedaling force is reduced along the lower pedaling force line RNL shown by the alternate long and short dash line in FIG. Then, in the pedal arm 20, the contact portion 27a comes into contact with the rest stopper 11i and stops at the rest position.

尚、運転者がアクセルペダル２８ａを戻す際に、ヒステリシス発生機構８０がスティック等によりハウジング１０の内壁に固着して戻らない場合であっても、主戻しバネ３０の付勢力により、上端部２７ｂが第１スライダ８１から離脱して、ペダルアーム２０は確実に休止位置に戻る。
したがって、位置センサ７０は、ペダルアーム２０が休止位置に戻ったことを検出するため、運転者の戻し動作と連動して所望の制御を行うことができる。
上記のように、運転者は、車両を運転する前に、切換ユニットＵを手動により操作して、アクセルペダル２８ａの反力を「重いモード」又は「軽いモード」のいずれかに選択的に切り換えることができる。 Even if the hysteresis generation mechanism 80 is stuck to the inner wall of the housing 10 by a stick or the like and does not return when the driver returns the accelerator pedal 28a, the upper end portion 27b is caused by the urging force of the main return spring 30. The pedal arm 20 surely returns to the resting position after being separated from the first slider 81.
Therefore, since the position sensor 70 detects that the pedal arm 20 has returned to the resting position, it is possible to perform desired control in conjunction with the return operation of the driver.
As described above, the driver manually operates the switching unit U before driving the vehicle to selectively switch the reaction force of the accelerator pedal 28a to either "heavy mode" or "light mode". be able to.

上記実施形態においては、切換ユニットＵが、回動部材５０及び操作部材６０により構成されているため、構造の簡素化、小型化等を達成しつつ、安価で、簡単な手動操作により軽重の二種類の踏力特性のいずれかを選択できるアクセルペダル装置を得ることができる。
また、ペダルアーム２０は、上記作用状態において回動部材５０が離脱しかつ上記非作用状態において副戻しバネ４０の付勢力により回動部材５０が当接する受け部２５を含むため、非作用状態において回動部材５０をペダルアーム２０の回動に確実に追従させて回動させることができ、副戻しバネ４０がペダルアーム２０に対して付勢力を及ぼさない非作用状態を確実に設定することができる。 In the above embodiment, since the switching unit U is composed of the rotating member 50 and the operating member 60, it is inexpensive and light and heavy by simple manual operation while achieving simplification and miniaturization of the structure. It is possible to obtain an accelerator pedal device that can select one of the types of pedaling force characteristics.
Further, since the pedal arm 20 includes a receiving portion 25 in which the rotating member 50 is detached in the operating state and the rotating member 50 is in contact with the urging force of the auxiliary return spring 40 in the non-acting state, the pedal arm 20 is in the non-acting state. The rotating member 50 can be reliably rotated by following the rotation of the pedal arm 20, and a non-acting state in which the secondary return spring 40 does not exert a urging force on the pedal arm 20 can be reliably set. can.

上記実施形態においては、主戻しバネ３０が伸縮コイルバネであり、副戻しバネ４０がペダルアーム２０の円筒部２１の領域に配置される捩りコイルバネであり、可動部材が副戻しバネ４０と同軸（軸線Ｓ）上において回動する回動部材５０であるため、部品の集約化、小型化等を達成することができる。
特に、回動部材５０の係合部５５がハウジング１０を通して外側に配置され、操作部材６０がハウジング１０の外側に往復動自在に保持されて、回動部材５０の回動を規制又は規制を解除できるように形成されているため、切換ユニットＵを、簡単な構造で安価に提供することができる。 In the above embodiment, the main return spring 30 is a telescopic coil spring, the sub-return spring 40 is a torsion coil spring arranged in the region of the cylindrical portion 21 of the pedal arm 20, and the movable member is coaxial with the sub-return spring 40 (axis line). Since the rotating member 50 rotates on S), it is possible to achieve integration of parts, miniaturization, and the like.
In particular, the engaging portion 55 of the rotating member 50 is arranged outside through the housing 10, and the operating member 60 is reciprocally held outside the housing 10 to restrict or release the rotation of the rotating member 50. Since it is formed so as to be capable, the switching unit U can be provided at low cost with a simple structure.

上記実施形態においては、回動部材５０、副戻しバネ４０、及び位置センサ７０が、軸線Ｓを中心とする同軸上に配置されて部品が集約されているため、装置の小型化に寄与する。また、主戻しバネ３０が、ペダルアーム２０の円筒部２１の近傍において上側アーム２７寄りに配置されているため、切換ユニットＵ（回動部材５０、副戻しバネ４０）及び位置センサ７０と併せて部品の集約化がなされ、装置全体としての小型化が達成される。 In the above embodiment, the rotating member 50, the sub-return spring 40, and the position sensor 70 are arranged coaxially with the axis S as the center, and the parts are integrated, which contributes to the miniaturization of the device. Further, since the main return spring 30 is arranged near the upper arm 27 in the vicinity of the cylindrical portion 21 of the pedal arm 20, the switching unit U (rotating member 50, sub-return spring 40) and the position sensor 70 are combined. The parts are integrated and the size of the device as a whole is reduced.

図１４及び図１５は、本発明の他の実施形態に係る切換ユニットＵ２を示すものであり、前述の実施形態と同一の構成については同一の符号を付して説明を省略する。

It is provided with a positioning protrusion 111q 2 that snap-engages the groove 163.
Then, the holding portion 111q exposes the operating portion 161 and penetrates the operating member 160 from the outside to the inside of the housing 10 to reciprocally hold the operating member 160 in the S direction of the axis.

回動部材１５０は、鍔部５１、嵌合穴５２、掛止部５３、当接部５４、係合部１５５を備えている。
係合部１５５は、ハウジング１０内に配置されて、軸線Ｓ方向に開口する係合穴として形成されている。 The rotating member 150 includes a flange portion 51, a fitting hole 52, a hooking portion 53, a contact portion 54, and an engaging portion 155.
The engaging portion 155 is arranged in the housing 10 and is formed as an engaging hole that opens in the axis S direction.

操作部１６１は、車両の運転者等が指で掴めるように外部に露出して配置される。
規制部１６２は、係合部１５５の係合穴に嵌合するように形成されている。
位置決め溝１６３は、Ｖ字状の断面をなすと共に軸線Ｓに垂直な方向に伸長する直線溝として形成され、操作部材１６０の往復動方向において離隔して配置された第１位置決め溝１６３ａ及び第２位置決め溝１６３ｂを備えている。 The operation member 160 is formed in a substantially rectangular rod shape using a resin material, a metal material, or the like, and includes an operation unit 161, a regulation unit 162, and a positioning groove 163.
The operation unit 161 is arranged so as to be exposed to the outside so that the driver of the vehicle or the like can grasp it with his / her fingers.
The restricting portion 162 is formed so as to fit into the engaging hole of the engaging portion 155.
The positioning groove 163 is formed as a linear groove having a V-shaped cross section and extending in a direction perpendicular to the axis S, and the first positioning groove 163a and the second positioning groove 163a and the second are arranged apart from each other in the reciprocating direction of the operating member 160. It is provided with a positioning groove 163b.

そして、図１５に示すように、操作部材１６０は、第１位置決め溝６３ａが保持部１１１ｑの位置決め突起１１１ｑ２と係合したとき、規制部１６２が係合部１５５に係合して、回動部材１５０の回動を規制する位置に位置決めされる。これにより、副戻しバネ４０がペダルアーム２０に対して付勢力を及ぼす作用状態が設定される。
一方、操作部材１６０は、第２位置決め溝１６３ｂが保持部１１１ｑの位置決め突起１１１ｑ２と係合したとき、規制部１６２が係合部１５５から離脱して、回動部材１５０の回動を許容する位置に位置決めされる。これにより、副戻しバネ４０がペダルアーム２０に対して付勢力を及ぼさない非作用状態が設定される。 Then, as shown in FIG. 15, when the first positioning groove 63a engages with the positioning projection 111q 2 of the holding portion 111q, the regulating portion 162 engages with the engaging portion 155 and rotates. It is positioned at a position that restricts the rotation of the member 150. As a result, the action state in which the sub-return spring 40 exerts a urging force on the pedal arm 20 is set.
On the other hand, when the second positioning groove 163b engages with the positioning projection 111q 2 of the holding portion 111q, the operating member 160 disengages the regulating portion 162 from the engaging portion 155 and allows the rotating member 150 to rotate. Positioned in position. As a result, the non-acting state in which the sub-return spring 40 does not exert a urging force on the pedal arm 20 is set.

この実施形態においても、切換ユニットＵ２が、回動部材１５０及び操作部材１６０により構成されているため、構造の簡素化、小型化等を達成しつつ、安価で、簡単な手動操作により軽重の二種類の踏力特性のいずれかを選択できるアクセルペダル装置を得ることができる。
特に、回動部材１５０の係合部１５５がハウジング１０の内側に配置され、操作部材１６０がハウジング１０の外側から内側に貫通して往復動自在に保持されて、回動部材１５０の回動を規制又は規制を解除できるように形成されているため、切換ユニットＵ２を、簡単な構造で安価に提供することができる。 Also in this embodiment, since the switching unit U2 is composed of the rotating member 150 and the operating member 160, it is inexpensive and light and heavy by simple manual operation while achieving simplification and miniaturization of the structure. It is possible to obtain an accelerator pedal device that can select one of the types of pedaling force characteristics.
In particular, the engaging portion 155 of the rotating member 150 is arranged inside the housing 10, and the operating member 160 penetrates from the outside to the inside of the housing 10 and is reciprocally held to rotate the rotating member 150. Since it is formed so that the regulation or the regulation can be lifted, the switching unit U2 can be provided at low cost with a simple structure.
