Further, the lower electromagnet 111D is fixed to the lower surface of the lower plate 114, respectively.

左右のガイド部材１１５，１１５の内面には、図３に示すように、往復動方向に延びるスライド溝１１５Ａ，１１５Ａが設けられ、両スライド溝１１５Ａ，１１５Ａに移動子１１２を保持する保持プレート１２０がスライド自在に支持されている。保持プレート１２０は、コロやベアリングによりガイド溝１１５Ａ内を滑動自在とできる。保持プレート１２０の前端には水平姿勢で往復動方向に延びる従動軸１２１の一端が取り付けられている。従動軸１２１は支持部１１３の外側に位置する軸受１２２にスライド自在に支持されている。 As shown in FIG. 3, slide grooves 115A and 115A extending in the reciprocating direction are provided on the inner surfaces of the left and right guide members 115 and 115, and a holding plate 120 for holding the moving element 112 in both slide grooves 115A and 115A.

The driven shaft 121 is slidably supported by a bearing 122 positioned outside the support portion 113.

保持プレート１２０に挟持された移動子１１２は、上面側がＮ極および下面側がＳ極となる磁石で、図１に示すように、平面視して往復動方向と直交する方向が長手方向となる直方体形状をなしている。移動子１１２の磁極に対応して、上側の電磁石１１１Ｕは、通電下で下面側がＳ極および上面側がＮ極となるように設定され、下側の電磁石１１１Ｄは、通電下で上面側がＮ極および下面側がＳ極となるように設定されている。 The moving element 112 sandwiched between the holding plates 120 is a magnet having an N pole on the upper surface side and an S pole on the lower surface side, and as shown in FIG. 1, a rectangular parallelepiped whose longitudinal direction is perpendicular to the reciprocating direction in plan view.

In the reciprocating section M of the moving element 112, the timing at which the intermittent switch unit 140 operates (current supply) and the timing at which the coil 118 enters the winding section L are synchronized.

回転部１３０は、ベース１０１上の他方側（図１の左側）に設置された一対の軸受１３１，１３１間に、クランク軸１３２の回転軸１３３，１３３が回転自在に支持され、クランク軸１３２の自由端側のクランクピン１３２Ａと従動軸１２１の他端が連結部材１３４により互いに連結された構成とされている。従動軸１２１の他端と連結部材１３４は連結ピン１３４Ａを介して屈曲可能に連結されている。間欠スイッチ部１４０の反対側に位置して、一方の回転軸１３３に始動レバー１３５の基端部が同軸的に連結されている。同始動レバー１３５はクランク軸１３２を回転始動させる役目をする。 The rotating unit 130 includes a pair of bearings 131 and 131 installed on the other side (the left side in FIG. 1) on the base 101. The rotating shafts 133 and 133 of the crankshaft 132 are rotatably supported. The crank pin 132A on the free end side and the other end of the driven shaft 121 are connected to each other by a connecting member 134. The other end of the driven shaft 121 and the connecting member 134 are connected via a connecting pin 134A so that they can be bent. Located on the opposite side of the intermittent switch part 140, the base end part of the start lever 135 is coaxially connected to one rotating shaft 133. The start lever 135 serves to start rotation of the crankshaft 132.

間欠スイッチ部１４０は、クランク軸１３２の回転に伴い往復動する移動子１１２の動きに連動して、各電磁石１１１Ｕ，１１１Ｄのコイル１１８に流れる電流の供給と遮断を一定のタイミングで間欠的に繰り返すもので、他方の回転軸１３３回りに回転子１４１が取り付けられ、回転子１４１の回転面の１８０度対称位置に一対の電極板１４２，１４２が設けられ、回転子１４１の前後一方に前記電極板１４２，１４２に所定の回転タイミングで接触し、通電を可能とする一対の接触ブラシ１４３，１４３が配置されている。接触ブラシ１４３，１４３はベース１０１上に支持されている。 The intermittent switch section 140 intermittently repeats the supply and interruption of the current flowing through the coils 118 of the electromagnets 111U and 111D at a fixed timing in conjunction with the movement of the moving element 112 that reciprocates as the crankshaft 132 rotates. A rotor 141 is attached around the other rotating shaft 133, and a pair of electrode plates 142, 142 are provided at 180 ° symmetrical positions on the rotating surface of the rotor 141. A pair of contact brushes 143 and 143 that are in contact with 142 and 142 at a predetermined rotation timing and enable energization are arranged. The contact brushes 143 and 143 are supported on the base 101.

間欠スイッチ部１４０は、回転子１４１の回転途中で、一対の電極板１４２，１４２が接触ブラシ１４３，１４３に同時に接触すると、その間通電し（作動オン）、電源部１５０からの電流が各コイル１１８に供給されるようになっている。また、一対の電極板１４２，１４２が接触ブラシ１４３，１４３から離間すると、その間通電が不可となり（作動オフ）、電源部１５０からの各コイル１１８への電流が遮断されるようになっている。より具体的には、移動子１１２の往復動区間Ｍにおいて、移動子１１２が一対の電磁石１１１Ｕ，１１１Ｄ間、すなわちコイル１１８の巻回区間Ｌに進入するタイミングで、各電極板１４２が接触ブラシ１４３に接触し、これにより電流供給が開始され、移動子１１２が一対の電磁石１１１Ｕ，１１１Ｄ間、すなわちコイル１１８の巻回区間Ｌの中心付近を通過するタイミングで各電極板１４２が接触ブラシ１４３から離間し、これにより電流の供給が遮断されるようになっている。 When the pair of electrode plates 142 and 142 are simultaneously in contact with the contact brushes 143 and 143 during the rotation of the rotor 141, the intermittent switch unit 140 is energized (operation is turned on) during that time, and the current from the power supply unit 150 is supplied to each coil 118. To be supplied. Further, when the pair of electrode plates 142 and 142 are separated from the contact brushes 143 and 143, energization is disabled during that time (operation is turned off), and the current from the power supply unit 150 to each coil 118 is cut off. More specifically, in the reciprocating section M of the moving element 112, each electrode plate 142 is connected to the contact brush 143 at the timing when the moving element 112 enters between the pair of electromagnets 111U and 111D, that is, the winding section L of the coil 118. Thus, current supply is started, and each electrode plate 142 is separated from the contact brush 143 at a timing when the moving element 112 passes between the pair of electromagnets 111U and 111D, that is, near the center of the winding section L of the coil 118. As a result, the supply of current is cut off.

電源部１５０は、各コイル１１８に電流を供給するもので、ケーブル１５１を介して各コイル１１８の一端にプラス側が、各コイル１１８の他端にマイナス側が接続されている。ケーブル１５１の途中には電源スイッチ１５２が接続されている。電力消費量が極めて少なく、電気の消耗が少ないことから、電源部１５０には１．５Ｖ程度の乾電池や小型バッテリーを用いることができる。 The power supply unit 150 supplies current to each coil 118, and a plus side is connected to one end of each coil 118 and a minus side is connected to the other end of each coil 118 via a cable 151. A power switch 152 is connected in the middle of the cable 151. Since the power consumption is extremely small and the consumption of electricity is small, a dry battery or a small battery of about 1.5 V can be used for the power supply unit 150.

図４および図５は、上記構成の補助動力装置１００において、クランク軸１３２の回転に連動して作動する間欠スイッチ部１４０に基づき、上下の電磁石１１１Ｕ，１１１Ｄ間の移動子１１２が持続的に往復動区間Ｍを往復ピストン運動する様子を示している。 4 and 5 show that the movable element 112 between the upper and lower electromagnets 111U and 111D continuously reciprocates based on the intermittent switch 140 that operates in conjunction with the rotation of the crankshaft 132 in the auxiliary power unit 100 configured as described above. A state in which the reciprocating piston motion is performed in the moving section M is shown.

最初に、手動で図１に示す始動レバー１３５を図２の反時計回りに回してクランク軸１３２を始動（回動）させる。往復動区間Ｍの往路において、図４（Ａ）に示すように、クランク軸１３２が始動してクランクピン１３２Ａが上死点から反時計回りに９０度を越えると、その途中で（このとき移動子１１２は上下の電磁石１１１Ｕ，１１１Ｄの隙間に左から進入する手前、すなわちコイル１１８の巻回区間Ｌに進入する手前に位置する）、間欠スイッチ部１４０の各電極板１４２が接触ブラシ１４３に同時に接触して通電可能となり、電源部１５０からの電流が各コイル１１８に供給開始される。 First, the crankshaft 132 is started (turned) by manually turning the start lever 135 shown in FIG. 1 counterclockwise in FIG. As shown in FIG. 4A, when the crankshaft 132 starts and the crankpin 132A exceeds 90 degrees counterclockwise from the top dead center in the forward path of the reciprocating section M, it moves in the middle (at this time, it moves The child 112 is positioned before entering the gap between the upper and lower electromagnets 111U and 111D from the left, that is, before entering the winding section L of the coil 118), and each electrode plate 142 of the intermittent switch unit 140 is simultaneously applied to the contact brush 143. The power supply unit 150 can be energized by contact, and supply of current from the power supply unit 150 to each coil 118 is started.

電源部１５０からの電流が各コイル１１８に流れると、上下の各コイル１１８に図６に示すように磁力線が生じ、図４（Ａ）に示すように移動子１１２を各コイル１１８，１１８間の隙間Ｓ_０に引き込む引張力Ｆ_１が生じる。すなわち、通電により、上側の電磁石１１１Ｕにはコイル１１８下側にＳ極が、下側の電磁石１１１Ｄにはコイル１１８上側にＮ極が形成され、移動子１１２の上側のＮ極とコイル１１８下側のＳ極が、移動子１１２の下側のＳ極とコイル１１８上側のＮ極がそれぞれ互いに引き合い、移動子１１２に右方向への引張力Ｆ_１すなわち往路の前進力が生じる。 When the current from the power supply unit 150 flows to each coil 118, magnetic lines of force are generated in the upper and lower coils 118 as shown in FIG. 6, and the moving element 112 is connected between the coils 118 and 118 as shown in FIG. A tensile force F ₁ that pulls into the gap S ₀ is generated. That is, by energization, the upper electromagnet 111U forms an S pole below the coil 118, and the lower electromagnet 111D forms an N pole above the coil 118. The upper N pole of the mover 112 and the lower side of the coil 118 are formed. The south pole of the moving element 112 and the north pole of the upper side of the coil 118 are attracted to each other, and a pulling force F ₁ in the right direction, that is, a forward traveling force is generated in the moving element 112.

次いで、図４（Ｂ）に示すように、クランク軸１３２のクランクピン１３２Ａが下死点に近づくと、その途中で（このとき移動子１１２は電磁石１１１Ｕ，１１１Ｄ間の中央付近を右に通過する）、間欠スイッチ部１４０の各電極板１４２が接触ブラシ１４３から離間し、電源部１５０からの電流供給が遮断される。クランク軸１３２および移動子１１２には慣性力が働いているから、クランク軸１３２は下死点から反時計回りに回動して上死点に向かうと共に、移動子１１２は往路を電磁石１１１Ｕ，１１１Ｄの隙間から外へと図４（Ｂ）の右方向へ移動する。 Next, as shown in FIG. 4B, when the crank pin 132A of the crankshaft 132 approaches the bottom dead center, the moving element 112 passes to the right near the center between the electromagnets 111U and 111D. ), Each electrode plate 142 of the intermittent switch unit 140 is separated from the contact brush 143, and the current supply from the power source unit 150 is cut off. Since the inertial force is acting on the crankshaft 132 and the mover 112, the crankshaft 132 rotates counterclockwise from the bottom dead center toward the top dead center, and the mover 112 travels forward in the electromagnets 111U and 111D. It moves to the right of FIG.

次いで、往復動区間Ｍの復路において、図５（Ａ）に示すように、クランク軸１３２のクランクピン１３２Ａが下死点を過ぎて９０度を越えると、その途中で（このとき移動子１１２は上下の電磁石１１１Ｕ，１１１Ｄの隙間に右から進入する手前、すなわちコイル１１８の巻回区間Ｌに進入する手前に位置する）、間欠スイッチ部１４０の各電極板１４２が接触ブラシ１４３に再び接触して、電源部１５０からの電流が各コイル１１８に供給される。同時に、各コイル１１８に流れる電流により、上下の各コイル１１８に磁力線が生じ、図５（Ａ）に示すように移動子１１２を各電磁石１１１Ｕ，１１１Ｄ間の隙間に引き込む引張力Ｆ_２が生じる。すなわち、通電により、再び上側の電磁石１１１Ｕにはコイル１１８下側にＳ極が、下側の電磁石１１１Ｄにはコイル１１８上側にＮ極が形成され、移動子１１２の上側のＮ極とコイル１１８下側のＳ極が、移動子１１２の下側のＳ極とコイル１１８上側のＮ極がそれぞれ互いに引き合い、移動子１１２に左方向への引張力Ｆ_２すなわち復路の前進力が生じる。 Next, in the return path of the reciprocating section M, as shown in FIG. 5A, when the crank pin 132A of the crankshaft 132 passes the bottom dead center and exceeds 90 degrees, on the way (at this time, the moving element 112 Each electrode plate 142 of the intermittent switch unit 140 comes into contact with the contact brush 143 again, and is positioned before entering the gap between the upper and lower electromagnets 111U and 111D from the right, that is, before entering the winding section L of the coil 118). The current from the power supply unit 150 is supplied to each coil 118. At the same time, the current flowing through each coil 118, magnetic force lines occur in the upper and lower coils 118, FIG. 5 (A) the electromagnets movers 112 as shown in 111U, the tensile force _{F 2} drawn into the gap between 111D occurs. That is, by energization, the upper electromagnet 111U again forms an S pole below the coil 118, and the lower electromagnet 111D forms an N pole above the coil 118. side S pole, tensile force F ₂ ie backward advancing force of the lower S-pole and the coil 118 above the N pole attract each other, the moving member 112 to the left of the moving element 112 occurs.

次いで、図５（Ｂ）に示すように、クランク軸１３２のクランクピン１３２Ａが上死点に近づくと、その途中で（このとき移動子１１２は電磁石１１１Ｕ，１１１Ｄ間の中央付近を左に通過する）、各電極板１４２が接触ブラシ１４３から再び離間して、電源部１５０からの電流供給が遮断される。クランク軸１３２および移動子１１２には慣性力が働いているから、クランク軸１３２はクランクピン１３２Ａが上死点に向かいかつ上死点を越えるように反時計回りに回動し、電磁石１１１Ｕ，１１１Ｄの隙間から外へと図５（Ｂ）の左方向へ移動する。 Next, as shown in FIG. 5B, when the crank pin 132A of the crankshaft 132 approaches the top dead center, the moving element 112 passes to the left near the center between the electromagnets 111U and 111D. ), The electrode plates 142 are separated from the contact brush 143 again, and the current supply from the power supply unit 150 is cut off. Since the inertial force is acting on the crankshaft 132 and the moving element 112, the crankshaft 132 rotates counterclockwise so that the crankpin 132A is directed to the top dead center and exceeds the top dead center, and the electromagnets 111U and 111D. It moves to the left of FIG.

移動子１１２は、ガイド部材１１５，１１５の各内面のガイド溝１１５Ａ内にスライド自在に支持された保持プレート１２０に保持されているから、安定した水平姿勢で円滑に往復動できる。 Since the mover 112 is held by the holding plate 120 slidably supported in the guide grooves 115A on the inner surfaces of the guide members 115 and 115, it can smoothly reciprocate in a stable horizontal posture.

このようにして、本発明の補助動力装置１００によると、クランク軸１３２の回転に連動して間欠的に電流の供給と遮断を行わせる間欠スイッチ部１４０の作動のタイミングと、上下の電磁石１１１Ｕ，１１１Ｄ間の隙間Ｓ_０に進入する移動子１１２のタイミングとを合わせることにより、移動子１１２をして上下の電磁石１１１Ｕ，１１１Ｄ間の隙間Ｓ_０を往復動させる磁力を断続的に移動子１１２に作用せしめ、これによって移動子１１２を持続的に往復ピストン運動させることができる。 Thus, according to the auxiliary power unit 100 of the present invention, the operation timing of the intermittent switch unit 140 that intermittently supplies and interrupts the current in conjunction with the rotation of the crankshaft 132, the upper and lower electromagnets 111U, by combining the timing of the moving element 112 entering into the gap _{S 0} between 111D, the upper and lower electromagnets 111U and the movable element 112, a magnetic force for reciprocating the gap _{S 0} between 111D to intermittently moving element 112 By acting, it is possible to continuously move the moving element 112 in the reciprocating piston motion.

さらに、本発明の補助動力装置１００によると、装置を小型化したまま、動力の出力増大を容易に図ることができる。すなわち、上下の電磁石１１１Ｕ，１１１Ｄおよび移動子１１２は、往復動方向および高さ方向に延在させることなく、図１に示すように往復動方向と直交する方向に延在させる（その結果、電磁石および移動子が左右方向に長い形状となり、コイルの巻回量も増大する）だけで、両方の磁力が増大し、移動子１１２の往復ピストン運動による動力の出力を増大させることができる。上下の電磁石１１１Ｕ，１１１Ｄおよび移動子１１２は、往復動方向に延在させないので、往復運動距離の範囲が長くなることがなく、装置が大型化しない。 Furthermore, according to the auxiliary power device 100 of the present invention, it is possible to easily increase the power output while the device is downsized. That is, the upper and lower electromagnets 111U and 111D and the moving element 112 are not extended in the reciprocating direction and the height direction, but are extended in a direction orthogonal to the reciprocating direction as shown in FIG. And the moving element has a shape that is long in the left-right direction, and the amount of winding of the coil increases), both magnetic forces increase, and the output of power by the reciprocating piston movement of the moving element 112 can be increased. Since the upper and lower electromagnets 111U and 111D and the mover 112 do not extend in the reciprocating direction, the range of the reciprocating distance is not increased, and the apparatus is not enlarged.

図７は、本発明の補助動力装置１００を自転車のフレーム２００に設置した例を示している。 FIG. 7 shows an example in which the auxiliary power device 100 of the present invention is installed on a bicycle frame 200.

図７に示すように、回転軸１３３の一端に連結された始動レバー１３５の自由端には運転者の足を乗せる回転自在なペダル２０１が連結され、回転軸１３３の他端には始動レバー１３５と１８０度反対向きに補助レバー２０２が連結されている。補助レバー２０２の自由端には運転者の足を乗せる他方の回転自在なペダル（図示せず）が連結されている。このとき往復作動部１１０は、フレーム２００に沿ってサドル部（図示せず）に向けて起立するように配置してよい。 As shown in FIG. 7, a free pedal 201 connected to one end of the rotating shaft 133 is connected to a rotatable pedal 201 on which the driver's foot can be put, and the other end of the rotating shaft 133 is connected to the starting lever 135. The auxiliary lever 202 is connected in the opposite direction of 180 degrees. The free end of the auxiliary lever 202 is connected to the other rotatable pedal (not shown) for placing the driver's foot. At this time, the reciprocating operation unit 110 may be arranged to stand along the frame 200 toward a saddle unit (not shown).

図４に示す補助動力装置１００によると、最初に電源部１５０の電源スイッチ１５２を入れ、運転者がペダル２０１をこいでクランク軸１３２を回動させると、図４に示すように、運転者がペダル２０１を強く踏み込むタイミングで、間欠スイッチ部１４０が作動し、各コイル１１８に電流が供給されて、一対の電磁石１１１Ｕ，１１１Ｄが、運転者のペダル２０１の踏み込み動作を助けるように移動子１１２を引っ張り、また、図５に示すように、ペダル２０１が持ち上がるタイミングで（他方のペダルを強く踏み込むタイミングでもある）、間欠スイッチ部１４０が再び作動し、各コイル１１８に電流が供給されて、一対の電磁石１１１Ｕ，１１１Ｄが、運転者のペダル２０１の踏み込み動作を助けるように移動子１１２を引っ張る。その結果、運転者が左右のペダルを踏み込む動作を常に助けるように、移動子１１２が持続的に往復ピストン運動する。 According to the auxiliary power unit 100 shown in FIG. 4, when the driver first turns on the power switch 152 of the power supply unit 150 and turns the crankshaft 132 by pushing the pedal 201, as shown in FIG. 4, the driver At the timing when the pedal 201 is strongly depressed, the intermittent switch unit 140 is activated, current is supplied to each coil 118, and the pair of electromagnets 111U and 111D causes the mover 112 to assist the driver 201 in depressing the pedal 201. As shown in FIG. 5, when the pedal 201 is lifted (also when the other pedal is strongly depressed), the intermittent switch unit 140 is actuated again, current is supplied to each coil 118, The electromagnets 111U and 111D pull the moving element 112 so as to assist the driver's stepping operation of the pedal 201. As a result, the moving element 112 continuously performs the reciprocating piston movement so as to always help the driver to depress the left and right pedals.

このように、移動子１１２に生じる往復ピストン運動は、従動軸１２１からクランク軸１３２の回転運動に変換され、運転者がペダルをこぐ際の補助動力として用いられる。これにより、従来の電動アシスト自転車に比べて、より軽量かつコンパクトで簡易な補助動力装置付きのアシスト自転車を安価に実現することができる。 As described above, the reciprocating piston motion generated in the moving element 112 is converted from the driven shaft 121 to the rotational motion of the crankshaft 132 and used as auxiliary power when the driver steps on the pedal. Thereby, compared with the conventional electrically assisted bicycle, a lighter, more compact and simple assist bicycle with an auxiliary power device can be realized at low cost.

なお、移動子１１２の従動軸１２１と反対側に出力軸を設け、往復ピストン運動を出力軸により外部に出力するようにしてよい。例えばミシン針の縫製作業に応用できる。出力軸を軸受で支えることにより、従動軸側の軸受との間で移動子が水平姿勢に保持され、左右のガイド部材を不要とする。 Note that an output shaft may be provided on the opposite side of the movable element 112 from the driven shaft 121, and the reciprocating piston motion may be output to the outside through the output shaft. For example, it can be applied to sewing operations of sewing needles. By supporting the output shaft with the bearing, the moving element is held in a horizontal posture with the bearing on the driven shaft side, and the left and right guide members are unnecessary.

本発明の補助動力装置は、例えば自転車、カート、芝刈り機、農業用機械、ミシン等の補助動力装置として、広く利用可能である。 The auxiliary power device of the present invention can be widely used as an auxiliary power device for bicycles, carts, lawnmowers, agricultural machines, sewing machines, and the like.
