Description

本発明は、移動体に設けた磁気発生素子と、固定部材に設けたスイッチ本体に配設し、前記磁気発生素子の磁気を感知可能に設けた磁気感応素子とを備え、移動体の移動に伴う磁気発生素子の磁気変化を磁気感応素子によって感知してスイッチ動作する非接触スイッチに関する。   The present invention includes a magnetism generating element provided on a moving body and a magnetism sensitive element provided on a switch body provided on a fixed member and capable of sensing the magnetism of the magnetism generating element. The present invention relates to a non-contact switch that performs a switching operation by detecting a magnetic change of a magnetic generation element with a magnetic sensing element.

磁気発生素子としてマグネット(永久磁石)を備え、磁気感応素子としてホール素子を備えた検出スイッチが実用化されている。
図9は、この種の検出スイッチの一例として示した車輌のストップランプスイッチを示す。
このストップランプスイッチは、ケーシング10がセンサ収納部11とロッド支持部12とから形成され、ロッド13がロッド支持部12内に移動可能に挿入されている。
A detection switch having a magnet (permanent magnet) as a magnetic generating element and a Hall element as a magnetic sensitive element has been put into practical use.
FIG. 9 shows a vehicle stop lamp switch shown as an example of this type of detection switch.
In this stop lamp switch, a casing 10 is formed of a sensor housing portion 11 and a rod support portion 12, and a rod 13 is movably inserted into the rod support portion 12.

上記ロッド13は、センサ収納部11内に設けられたスプリング14によってロッド支持部12から突出する方向の押動勢力を受けているが、足離し状態のブレーキペダルのレバー15によって押し戻されて図9に示す位置に保っている。
また、センサ収納部11内となっているロッド13の基部には、マグネット16が取付けられている。
さらに、センサ収納部11内には、ホール素子17を備える回路基板18が磁路板19と共に取付けられている。
The rod 13 receives a pushing force in a direction protruding from the rod support portion 12 by a spring 14 provided in the sensor housing portion 11, but is pushed back by a lever 15 of a brake pedal in a released state and is shown in FIG. It is kept in the position shown in.
A magnet 16 is attached to the base of the rod 13 in the sensor housing 11.
Further, a circuit board 18 including a hall element 17 is attached together with a magnetic path plate 19 in the sensor housing portion 11.

なお、このストップランプスイッチは、ブラケット20を用いて車体部に取付けられており、また、回路基板18がコネクタ21を介して外部装置に電気接続されている。 The stop lamp switch is attached to the vehicle body using a bracket 20, and the circuit board 18 is electrically connected to an external device via a connector 21.

上記したストップランプスイッチは、ブレーキペダルを踏み込まない状態では、このブレーキペダルに加わる復帰勢力でレバー15が復動するため、ロッド13が図9に示すように後退している。
この動作状態では、ホール素子17がマグネット16の一方磁極(例えば、N極)の磁界を受けることから、OFFのスイッチ動作となる。
In the stop lamp switch described above, when the brake pedal is not depressed, the lever 15 is moved backward by the return force applied to the brake pedal, so that the rod 13 is retracted as shown in FIG.
In this operation state, the Hall element 17 receives the magnetic field of one magnetic pole (for example, N pole) of the magnet 16, and therefore the switch operation is OFF.

一方、ブレーキペダルを踏み込むと、図10に示す如く、レバー15がロッド13から離れように移動するため、ロッド13がスプリング14のばね勢力によってロッド支持部12から突出方向に移動する。
この動作状態では、ホール素子17がマグネット16の他方磁極(例えば、S極)の磁界を受けることから、ONのスイッチ動作となる。
On the other hand, when the brake pedal is depressed, the lever 15 moves away from the rod 13 as shown in FIG. 10, so that the rod 13 moves in the protruding direction from the rod support portion 12 by the spring force of the spring 14.
In this operation state, the Hall element 17 receives the magnetic field of the other magnetic pole (for example, the S pole) of the magnet 16, and therefore the ON switch operation is performed.

特開2006−92777号公報JP 2006-92777 A

上記した従来の検出スイッチは、ブレーキペダルの復動により、そのレバー15が強い移動力でロッド13に衝突する構成であるため、レバーの衝突が多くなるにつれてロッド13が破壊し安いスイッチとなる。
また、ロッド13とロッド支持部12の摺動部の隙間から塵、埃や水などが浸入することにより、マグネット16や回路基板18に付着して、故障の原因となる恐れがある。
その上、このようなスイッチでは、ロッド13とロッド支持部12の摺動部に潤滑材を塗布されているが、その潤滑材がシリコン系の潤滑材である場合には、腐食性ガス等を発生する可能性があり、その腐食性ガス等が隙間から浸入して接点部が腐食されてしまう恐れもある。
The above-described conventional detection switch has a configuration in which the lever 15 collides with the rod 13 with a strong moving force when the brake pedal returns, so that the rod 13 is broken and becomes a cheap switch as the lever collision increases.
Further, when dust, dust, water, or the like enters from a gap between the sliding portion of the rod 13 and the rod support portion 12, it may adhere to the magnet 16 or the circuit board 18 and cause a failure.
In addition, in such a switch, a lubricant is applied to the sliding portion of the rod 13 and the rod support portion 12, but when the lubricant is a silicon-based lubricant, a corrosive gas or the like is used. There is also a possibility that the corrosive gas or the like may enter from the gap and the contact portion may be corroded.

さらに、ロッド13の移動距離が決まっているため、マグネット16が一定の範囲で移動するにすぎないために、ホール素子17が受ける磁界の強さを調整することができない。
この結果、スイッチの感度調整が困難であり、また、機械的な耐久性の低い検出スイッチとなる。
Furthermore, since the moving distance of the rod 13 is determined, the magnet 16 only moves within a certain range, so that the strength of the magnetic field received by the Hall element 17 cannot be adjusted.
As a result, it is difficult to adjust the sensitivity of the switch, and the detection switch has low mechanical durability.

本発明は、上記した実情にかんがみ、高い感度調整ができる上、機械的な耐久性に優れる非接触動作の検出スイッチを提案すること目的とする。 In view of the above circumstances, an object of the present invention is to propose a non-contact operation detection switch that can perform high sensitivity adjustment and is excellent in mechanical durability.

また、上記した第1又は第2の発明の非接触スイッチは、前記磁気感応素子をターミナルベースと共にスイッチケースの容状部に収納させる回路基板に設け、かつ、前記磁気調整部材の軸線上に配置する構成とすることが好ましい。 The non-contact switch according to the first or second aspect of the invention is provided on a circuit board that houses the magnetically sensitive element together with a terminal base in a container case, and is disposed on the axis of the magnetic adjustment member. It is preferable to adopt a configuration to do so.

上記した本発明は、磁気発生素子を移動部材に設け、磁気感応素子を固定部材に取付けたスイッチケースに設け、これら磁気発生素子と磁気感応素子との間に所定の距離を設けた非接触のスイッチとして構成したので、機械的に耐久性の高いスイッチとなる。   The present invention described above is a non-contact type in which a magnetism generating element is provided on a moving member, a magnetism sensitive element is provided on a switch case attached to a fixed member, and a predetermined distance is provided between the magnetism generating element and the magnetism sensitive element. Since it is configured as a switch, it becomes a mechanically durable switch.

このようにすれば、磁気調整部材による磁界調整に加えてスイッチ本体の取付位置による磁界調整が可能になるので、感度の微調整に適するスイッチとなる。
Furthermore, since the switch body can be mounted at different positions by the mounting adjustment member, this adjusts the distance between the cylindrical portion or the magnetic adjustment member relative to the magnetism generating element.
That is, the distance between the cylindrical part of the switch case or the magnetic adjustment member and the magnetic generation element is changed to adjust the strength of the magnetic field received by the magnetically sensitive element from the magnetic generation element.

次に、本発明をブレーキランプスイッチ(ストップランプスイッチ)として実施する一実施形態について図面に沿って説明する。
図1は、ブレーキランプスイッチを備えた車輌のブレーキペダルを示す概略構成図である。
Next, an embodiment in which the present invention is implemented as a brake lamp switch (stop lamp switch) will be described with reference to the drawings.
FIG. 1 is a schematic configuration diagram showing a brake pedal of a vehicle provided with a brake lamp switch.

図示するように、ブレーキペダル30は、ペダル部31を有するアーム部32が支軸33により車体の一部に回転可能に軸支された構成となっている。
なお、このブレーキペダル30の場合は、アーム部32と一体回転する回転レバー34を備え、この回転レバー34と車体固定部35との間に復動用のスプリング36を設け、また、このスプリング36のばね勢力によるアーム部32の回転(図1では左回転)を回転レバー34に設けたストッパー37と車体固定部35に設けたストッパー受け38とによって受け止めている。
As shown in the figure, the brake pedal 30 has a configuration in which an arm portion 32 having a pedal portion 31 is rotatably supported by a part of a vehicle body by a support shaft 33.
In the case of the brake pedal 30, a rotation lever 34 that rotates integrally with the arm portion 32 is provided, and a return spring 36 is provided between the rotation lever 34 and the vehicle body fixing portion 35. The rotation (left rotation in FIG. 1) of the arm portion 32 by the spring force is received by a stopper 37 provided on the rotation lever 34 and a stopper receiver 38 provided on the vehicle body fixing portion 35.

ブレーキランプスイッチ50は、スイッチ本体51とスイッチ移動体52とからなる非接触スイッチとして構成してある。
そして、スイッチ本体51は、取付調整部材53を介在させて車体固定部35に固着した取付板54に取付けてある。
また、スイッチ移動体52は、スイッチ本体51との間に距離Dを設けるようにしてアーム部32の一部に設けた突片55に固着してある。
The brake lamp switch 50 is configured as a non-contact switch including a switch body 51 and a switch moving body 52.
The switch body 51 is attached to an attachment plate 54 fixed to the vehicle body fixing portion 35 with an attachment adjustment member 53 interposed therebetween.
The switch moving body 52 is fixed to a projecting piece 55 provided on a part of the arm portion 32 so as to provide a distance D between the switch moving body 52 and the switch body 51.

図2は上記のスイッチ本体51を示し、(A)図は側面図、(B)図は正面図、(C)図は背面図である。
また、図3は図2(B)上のA―A線断面図である。
2A and 2B show the switch body 51, wherein FIG. 2A is a side view, FIG. 2B is a front view, and FIG. 2C is a rear view.
FIG. 3 is a cross-sectional view taken along line AA in FIG.

これらの図面より分かるように、このスイッチ本体51は、有底の容状部56と、この容状部56の底外面に延設した円筒状部57とで形成した合成樹脂材からなるスイッチケースと、このスイッチケースの容状部56に内装したターミナルベース58及びその円筒状部57内に挿入した磁気調整部材59とより構成してある。
そして、円筒状部57と容状部56との間には、壁部57bが形成されており、これら円筒状部57と容状部56とを分離させた構成としてある。
As can be seen from these figures, the switch case the switch body 51 is, to a volume-like portion 56 of the bottom, consisting of forming the synthetic resin material in a cylindrical portion 57 extending to the bottom outer surface of the volume-like portion 56 And a terminal base 58 housed in the container portion 56 of the switch case and a magnetic adjustment member 59 inserted into the cylindrical portion 57.
A wall portion 57b is formed between the cylindrical portion 57 and the container portion 56, and the cylindrical portion 57 and the container portion 56 are separated from each other.

ターミナルベース58は合成樹脂材などの電気絶縁材で形成し、電源回路やブレーキランプなどの外部装置と接続するコネクタ60を備えると共に、ホール素子61やスイッチ回路などを有する回路基板62が設けてある。
このターミナルベース58は、図3の断面図に示す如く、回路基板62を底面側にしてスイッチケースの容状部56に内装してあるが、その周囲の係止部58aを容状部56の係止孔に係止させて抜け止めしてある。
The terminal base 58 is formed of an electrical insulating material such as a synthetic resin material, and includes a connector 60 for connecting to an external device such as a power supply circuit and a brake lamp, and a circuit board 62 having a hall element 61 and a switch circuit. .
As shown in the cross-sectional view of FIG. 3, the terminal base 58 is housed in the switch case container 56 with the circuit board 62 on the bottom side. It is locked in the locking hole to prevent it from coming off.

また、このターミナルベース58は、容状部56内に収納させるとき、容状部56内周の断形部との間でパッキン63を挟持させることによって、容状部56内が密封構造となり、容状部56内に入り込む水や塵、埃、さらには腐食性ガス等の浸入を確実に防止するようにしてある。 Further, when the terminal base 58 is housed in the container part 56, the inside of the container part 56 becomes a sealed structure by sandwiching the packing 63 between the cut part of the inner periphery of the container part 56, Intrusion of water, dust, dust, corrosive gas, and the like entering the container 56 is reliably prevented.

さらに、ターミナルベース58が上記のように容状部56内に収納されると、回路基板62に設けたホール素子61が、スイッチケースの円筒状部57の筒軸線上に配設されるようになっている。 Further, when the terminal base 58 is housed in the container portion 56 as described above, the Hall element 61 provided on the circuit board 62 is disposed on the cylinder axis of the cylindrical portion 57 of the switch case. It has become.

すなわち、スイッチケースの円筒状部57と容状部56との間に壁部57bを設け、この壁部57bに円筒状部57を突設形成し、かつ、この円筒状部57に磁気調整部材59を挿入する構成としたので、ホール素子61を磁気調整部材59と対応する位置に配置することができるようになっている。   That is, a wall portion 57b is provided between the cylindrical portion 57 and the container portion 56 of the switch case, the cylindrical portion 57 is formed to project from the wall portion 57b, and the magnetic adjustment member is provided on the cylindrical portion 57. 59 is inserted, the Hall element 61 can be disposed at a position corresponding to the magnetic adjustment member 59.

このようにホール素子61を磁気調整部材59の軸線上に配置することにより、ホール素子61の感度を低下させることがない(従来技術のように磁気調整部材59の軸線に対して垂直となるように配置すると、磁界が回りこまないと検出できない場合がある。)ので、後述するマグネット66の磁力を不必要に強くする必要がなくなるため、マグネット66への塵(特に砂鉄)の付着を防止することができる。   By arranging the Hall element 61 on the axis of the magnetic adjustment member 59 in this way, the sensitivity of the Hall element 61 is not reduced (so as to be perpendicular to the axis of the magnetic adjustment member 59 as in the prior art). In this case, since it is not necessary to increase the magnetic force of the magnet 66 which will be described later unnecessarily, the adhesion of dust (especially iron sand) to the magnet 66 is prevented. be able to.

上記した磁気調整部材59は、強磁性材で形成した円形断面の長形体で、図4に示してある通り、その一方側に雄ねじ59aが形成してあり、さらに、その一端面には、操作部としての凹形溝59bが設けてある。
この磁気調整部材59は、スイッチケースの円筒状部57内周に形成した雌ねじ57aにねじ込むようにして、この円筒状部57内に挿入してある。
なお、円筒状部57の雌ねじ57aは、磁気調整部材59の雄ねじ59aのねじ範囲L0に比べて充分に長くしたL1の範囲に形成してある。
The above-described magnetic adjustment member 59 is a long section having a circular cross section formed of a ferromagnetic material. As shown in FIG. 4, a male screw 59a is formed on one side of the magnetic adjustment member 59. A concave groove 59b is provided as a part.
The magnetic adjustment member 59 is inserted into the cylindrical portion 57 so as to be screwed into a female screw 57a formed on the inner periphery of the cylindrical portion 57 of the switch case.
The female screw 57a of the cylindrical portion 57 is formed in a range L1 that is sufficiently longer than the screw range L0 of the male screw 59a of the magnetic adjustment member 59.

また、磁気調整部材59は、後述するマグネット66の磁力をホール素子61に効率よく伝達するため、調整移動量を考慮して、できるだけホール素子61の近傍となる位置に一端部が延設されるように構成することが好ましい。   In addition, the magnetic adjustment member 59 has one end extending as close to the Hall element 61 as possible in consideration of the adjustment movement amount in order to efficiently transmit the magnetic force of the magnet 66 described later to the Hall element 61. It is preferable to configure as described above.

なお、磁気調整部材59の雄ねじ59aは、磁気調整部材59の全体に亘って形成してもよく、円筒状部57の雌ねじ57aの形成範囲も適宜に調整移動量を考慮して適宜に決定すればよい。   The male screw 59a of the magnetic adjustment member 59 may be formed over the entire magnetic adjustment member 59, and the formation range of the female screw 57a of the cylindrical portion 57 is appropriately determined in consideration of the adjustment movement amount. That's fine.

さらに、スイッチケースの円筒状部57の外周には、図2(A)、図2(B)、図3に示す如く、円筒軸方向に沿って長く形成した突条部64とねじ状部65とが設けてある。
つまり、2つの突条部64が筒軸線を挟んで対称的に形成し、同様に2つのねじ状部65が筒軸線を挟んで対称的に形成してある。
この突条部64とねじ状部65は、後述する取付調整部材とでスイッチ本体51の取付位置を調整するためのものである。
Further, on the outer periphery of the cylindrical portion 57 of the switch case, as shown in FIGS. 2A, 2B, and 3, a protruding ridge portion 64 and a screw-like portion 65 formed long along the cylindrical axis direction. Are provided.
That is, the two protrusions 64 are formed symmetrically with the cylinder axis line in between, and similarly, the two screw-like parts 65 are formed symmetrically with the cylinder axis line in between.
The protrusion 64 and the threaded portion 65 are for adjusting the mounting position of the switch body 51 with an attachment adjusting member described later.

このように円筒状部57にねじ状部65を設けてスイッチ本体51の取付位置を調整するようにした場合でも、円筒状部57には強磁性体で形成された強度のある磁気調整部材59が挿入されているので、特に強度を持たせる構造とする必要はなく、さらに円筒状部57を細く形成することができる。
特に、ブレーキスイッチ等のように取付場所が狭い場合には、スイッチ本体51を小型化することができるので好適である。
Thus, even when the screw portion 65 is provided in the cylindrical portion 57 and the mounting position of the switch body 51 is adjusted, the cylindrical portion 57 has a strong magnetic adjustment member 59 formed of a ferromagnetic material. Therefore, it is not necessary to make the structure particularly strong, and the cylindrical portion 57 can be formed thinner.
In particular, when the mounting location is narrow, such as a brake switch, the switch body 51 can be downsized, which is preferable.

一方、スイッチ移動体52は、図5、図6に示す構成としてある。
なお、図5(A)はスイッチ移動体52の側面図、図5(B)は同スイッチ移動体52の正面図、図5(C)は同スイッチ移動体52の背面図であり、また、図6は図5(B)上のB−B線断面図である。
On the other hand, the switch moving body 52 is configured as shown in FIGS.
5A is a side view of the switch moving body 52, FIG. 5B is a front view of the switch moving body 52, FIG. 5C is a rear view of the switch moving body 52, and FIG. 6 is a cross-sectional view taken along line BB in FIG.

このスイッチ移動体52は、マグネット(永久磁石)66の一面を背面に露出させた合成樹脂材からなる円盤状部52aと、円盤状部52aの正面中央に一体に設けた突設部52bとから構成してある。   The switch moving body 52 includes a disc-shaped portion 52a made of a synthetic resin material with one surface of a magnet (permanent magnet) 66 exposed on the back surface, and a projecting portion 52b integrally provided at the front center of the disc-shaped portion 52a. It is configured.

なお、このスイッチ移動体52は、突設部52bに首部52cを形成し、突設部52bをアーム部32に形成にした取付孔(図示せず)に突入させ、その首部52cによって抜け止めするようになっている。
なお、突設部52bに設けた長孔52dは、突設部52bを弾性的に細形縮小させるためのものである。
The switch moving body 52 has a neck portion 52c formed in the projecting portion 52b, and the projecting portion 52b is projected into an attachment hole (not shown) formed in the arm portion 32, and is prevented from being detached by the neck portion 52c. It is like that.
The elongated hole 52d provided in the protruding portion 52b is for elastically reducing the size of the protruding portion 52b.

上記したスイッチ本体は、取付板54に取付けた取付調整部材53に差し入れるようにして取付ける。
この取付調整部材53については、図7(A)に正面図、図7(B)に側面図として示し、図7(C)には図7(A)上のC−C線断面図として示してある。
The switch body described above is attached so as to be inserted into the attachment adjusting member 53 attached to the attachment plate 54.
The mounting adjustment member 53 is shown as a front view in FIG. 7 (A), as a side view in FIG. 7 (B), and as a cross-sectional view along line CC in FIG. 7 (A). It is.

これらの図面より分かる通り、この取付調整部材53は、円形板部53aと、この円形板部53aに一体形成した短筒部53bとから構成してある。
そして、短筒部53bの外周囲には、取付回転位置を決める凸形部53cと、抜け止めを計る弾性係止部53dとが設けてある。
As can be seen from these drawings, the attachment adjusting member 53 includes a circular plate portion 53a and a short cylindrical portion 53b integrally formed with the circular plate portion 53a.
And the outer periphery of the short cylinder part 53b is provided with the convex part 53c which determines an attachment rotation position, and the elastic latching | locking part 53d which measures removal prevention.

さらに、この取付調整部材53の短筒部53bの内面には、その筒軸方向にそって形成し、上記した円筒状部57のねじ状部65を係合させるねじ状部67を設け、また、短筒部53bに連通する円形板部53aの孔縁には、上記円筒状部57を挿入する挿入孔縁68と、円筒状部57の突条部64を係止する係止孔縁69が設けてある。 Further, on the inner surface of the short cylindrical portion 53b of the attachment adjusting member 53, there is provided a screw-like portion 67 that is formed along the cylindrical axis direction and engages the screw-like portion 65 of the cylindrical portion 57 described above. The hole edge of the circular plate portion 53a that communicates with the short cylinder portion 53b has an insertion hole edge 68 for inserting the cylindrical portion 57 and a locking hole edge 69 for locking the protruding portion 64 of the cylindrical portion 57. Is provided.

図8は、前記の取付調整部材53を介在させて上記のスイッチ本体51を取り付ける上記取付板54の部分図である。
図示するように、この取付板54には、取付調整部材53を取付ける取付孔54aが形成してある。
FIG. 8 is a partial view of the mounting plate 54 for mounting the switch body 51 with the mounting adjustment member 53 interposed.
As shown in the figure, the mounting plate 54 is formed with a mounting hole 54a for mounting the mounting adjusting member 53.

そして、この取付孔54aには、図示の如く、取付調整部材53の短筒部53bを挿入する円形状の孔縁54bと、その凸形部53cを挿入する角状凹形縁54cとが中心軸上に対称的に設けてある。 As shown in the figure, the mounting hole 54a has a circular hole edge 54b into which the short cylindrical portion 53b of the attachment adjusting member 53 is inserted and a rectangular concave edge 54c into which the convex portion 53c is inserted. It is provided symmetrically on the axis.

取付調整部材53は、その短筒部53bを前記の取付孔54aに挿入して取り付けるが、この場合、短筒部53bの凸形部53cを凹形縁54cに嵌合させ、また、弾性係止部53dが一旦内方向に曲がりながら孔縁54bを通り越すようにする。 The attachment adjusting member 53 is attached by inserting the short cylinder portion 53b into the attachment hole 54a. In this case, the convex portion 53c of the short cylinder portion 53b is fitted to the concave edge 54c, and the elastic engagement member 53 is provided. The stopping portion 53d passes through the hole edge 54b while bending inward once.

このように短筒部53bを取付孔54aに挿入すると、凸形部53cと凹形縁54cによって取付調整部材53が非回転となり、また、弾性係止部53dが取付板54の裏面によって係止されるため、取付調整部材53が抜け止めされる。 When the short cylindrical portion 53b is inserted into the mounting hole 54a in this way, the mounting adjustment member 53 is not rotated by the convex portion 53c and the concave edge 54c, and the elastic locking portion 53d is locked by the back surface of the mounting plate 54. Therefore, the attachment adjusting member 53 is prevented from coming off.

取付調整部材53を取付板54に取付けた後、スイッチ本体51の円筒状部57をこの取付調整部材53の短筒部53b内に挿入する。
円筒状部57を挿入するに当たっては、その突条部64とねじ状部65を挿入孔縁68より挿入し、続いてスイッチ本体51を回転し、円筒状部57の突条部64が係止孔縁69を乗り越えるようにする。
After the attachment adjustment member 53 is attached to the attachment plate 54, the cylindrical portion 57 of the switch body 51 is inserted into the short cylinder portion 53 b of the attachment adjustment member 53.
In inserting the cylindrical portion 57, the protruding portion 64 and the threaded portion 65 are inserted from the insertion hole edge 68, and then the switch body 51 is rotated so that the protruding portion 64 of the cylindrical portion 57 is locked. Get over the hole edge 69.

このように回転すると、円筒状部57のねじ状部65が短筒部53b内のねじ状部67に嵌合し、この嵌合によって取付孔54aからの円筒状部57の抜け止めがなされ、さらに、円筒状部57の突条部64が係止孔縁69により係止され、円筒状部57の戻り回転が防止されるため、スイッチ本体51が取付板54に確実に取付けられる。 When rotating in this way, the threaded portion 65 of the cylindrical portion 57 is fitted into the threaded portion 67 in the short tubular portion 53b, and this fitting prevents the cylindrical portion 57 from coming off from the mounting hole 54a. Furthermore, since the protrusion 64 of the cylindrical portion 57 is locked by the locking hole edge 69 and the return rotation of the cylindrical portion 57 is prevented, the switch body 51 is securely attached to the mounting plate 54.

なお、取付調整部材53は、ねじ状部67のみを有するナット部材としてもよい。例えば、2つのナット部材により、取付板54を挟み込んで円筒状部57のねじ状部65を締め付けるようにスイッチ本体51を取り付けるようにしてもよく、上記した円筒状部57と取付調整部材53との取付構造に限られるものではなく、適宜に設定することができる。   Note that the attachment adjusting member 53 may be a nut member having only the threaded portion 67. For example, the switch body 51 may be attached by two nut members so as to sandwich the attachment plate 54 and tighten the screw-like portion 65 of the cylindrical portion 57. The cylindrical portion 57 and the attachment adjusting member 53 described above The mounting structure is not limited to this, and can be set as appropriate.

上記のように構成したブレーキランプスイッチ50は、運転者の足がブレーキペダル30から離れている状態では、図1に示すように、ブレーキペダル30が復動した状態となっているから、スイッチ移動体52がスイッチ本体51に最も接近した動作状態となっている。
したがって、スイッチ移動体52のマグネット66が距離Dの間隔で磁気調整部材59と対向するから、マグネット66の磁界が磁気調整部材59を通ってホール素子61に強く及ぶ状態となっている。
The brake lamp switch 50 configured as described above is in a state in which the brake pedal 30 is moved backward as shown in FIG. 1 when the driver's foot is away from the brake pedal 30. The body 52 is in the operating state closest to the switch body 51.
Accordingly, since the magnet 66 of the switch moving body 52 faces the magnetic adjustment member 59 at a distance D, the magnetic field of the magnet 66 is strongly applied to the Hall element 61 through the magnetic adjustment member 59.

これより、ホール素子61は所定レベル以上の磁束密度を検出しているため、検出信号SHを出力する。
そして、この検出信号SHは、スイッチ移動体52が図1に示す位置、つまり、ブルーキペダル30が復動している位置からブレーキペダルの遊び量を含む所定範囲(ブレーキ制御が行なわれない範囲)にブレーキペダル30が位置していることを示す検出信号である。
As a result, the Hall element 61 detects a magnetic flux density of a predetermined level or higher, and therefore outputs a detection signal SH.
The detection signal SH is a predetermined range including the play amount of the brake pedal from the position shown in FIG. 1, that is, the position where the brake pedal 30 is moved backward (the range where the brake control is not performed). ) Is a detection signal indicating that the brake pedal 30 is positioned.

ホール素子61の上記の検出信号SHは、回路基板62などに設けられているブレーキランプ回路に送られ、このランプ回路が上記の検出信号SHに応動してプレーキランプを消灯させる。 The detection signal SH of the Hall element 61 is sent to a brake lamp circuit provided on the circuit board 62 and the like, and the lamp circuit turns off the brake lamp in response to the detection signal SH.

運転者がブレーキペダル30を踏み込むと、アーム部32が支軸33を中心に時計方向に旋回し、スイッチ移動体52もアーム部32と一体に同方向に旋回することから、スイッチ移動体52がスイッチ本体51から遠ざかる。
つまり、マグネット66が円筒状部57の筒軸線上から外れた位置となり、さらに、磁気調整部材59より遠ざかるために、ホール素子61に及ぶマグネット66の磁界が弱くなる。
When the driver depresses the brake pedal 30, the arm portion 32 turns clockwise about the support shaft 33, and the switch moving body 52 also turns together with the arm portion 32 in the same direction. Move away from the switch body 51.
In other words, since the magnet 66 is positioned away from the cylinder axis of the cylindrical portion 57 and further away from the magnetic adjustment member 59, the magnetic field of the magnet 66 that extends to the Hall element 61 becomes weak.

この結果、ホール素子61は検出している磁束密度が所定レベル以下となるため検出信号SLを出力する。
この検出信号SLは、ブレーキペダル30が踏み込まれたことを示す検出信号であり、ブレーキランプ回路がその検出信号SLに応動してブレーキランプを点灯させる。
As a result, the Hall element 61 outputs a detection signal SL because the detected magnetic flux density is below a predetermined level.
The detection signal SL is a detection signal indicating that the brake pedal 30 has been depressed, and the brake lamp circuit lights the brake lamp in response to the detection signal SL.

なお、ブレーキランプ点灯のタイミングは、ホール素子61の磁界検出レベルとマグネット66の磁力を設定することによって基本的には調節されるものであるが、以下のように磁気調整部材59とホール素子61との距離を変えることによって容易に調整することができる。 The timing of turning on the brake lamp is basically adjusted by setting the magnetic field detection level of the hall element 61 and the magnetic force of the magnet 66, but the magnetic adjustment member 59 and the hall element 61 are as follows. It can be easily adjusted by changing the distance between.

上記した実施形態より分かるように、磁気調整部材59を回転し、この磁気調整部材59をねじ込み、或いは、ねじ戻しすれば、磁気調整部材59が円筒状部57内で移動するから、この磁気調整部材59とスイッチ移動体52との間及び磁気調整部材59とホール素子61の間の距離を変えることができる。 As can be seen from the above-described embodiment, if the magnetic adjustment member 59 is rotated and the magnetic adjustment member 59 is screwed or unscrewed, the magnetic adjustment member 59 moves in the cylindrical portion 57. The distances between the member 59 and the switch moving body 52 and between the magnetic adjustment member 59 and the Hall element 61 can be changed.

したがって、磁気調整部材59によってホール素子61に及ぶマグネット66の磁界の強さを調整することができるから、ホール素子の動作感度の違いによる調整、その他のスイッチの動作感度の調整などについて上記の磁気調整部材59によって容易に行うことができる。 Therefore, the magnetic adjustment member 59 can adjust the strength of the magnetic field of the magnet 66 that reaches the Hall element 61. Therefore, the above-described magnetism is adjusted with respect to the adjustment due to the difference in the operation sensitivity of the Hall element, the adjustment of the operation sensitivity of other switches, and the like. This can be easily performed by the adjustment member 59.

なお、実験の結果、磁気調整部材59のねじ込みを深くしてホール素子61と磁気調整部材59の間の距離を短くするにしたがいホール素子61の出力レベルが高くなることが確認された。   As a result of the experiment, it was confirmed that the output level of the Hall element 61 increases as the screwing of the magnetic adjustment member 59 is deepened to shorten the distance between the Hall element 61 and the magnetic adjustment member 59.

したがって、ブレーキペダルの踏込み直後にブレーキランプを点灯させるようにする場合は、ホール素子61と磁気調整部材59との間の距離を長くするように、磁気調整部材59のねじ込み深さを浅くし、他方、ブレーキペダルを十分に踏込んだときにブレーキランプを点灯させるようにする場合は、ホール素子61と磁気調整部材59との間の距離を短くするように、磁気調整部材59のねじ込みを深くするように調整すればよい。   Therefore, when the brake lamp is turned on immediately after the brake pedal is depressed, the screwing depth of the magnetic adjustment member 59 is made shallow so that the distance between the hall element 61 and the magnetic adjustment member 59 is increased. On the other hand, when the brake lamp is lit when the brake pedal is fully depressed, the magnetic adjustment member 59 is deeply screwed so as to shorten the distance between the hall element 61 and the magnetic adjustment member 59. You just have to adjust it.

また、取付調整部材53によってスイッチ本体51の取付け位置を変え、円筒状部57または磁気調整部材59とスイッチ移動体52との間の距離Dを変えて感度調整することができる。 Further, it is possible to adjust the sensitivity by changing the mounting position of the switch body 51 by the mounting adjusting member 53 and changing the distance D between the cylindrical portion 57 or the magnetic adjusting member 59 and the switch moving body 52.

すなわち、取付板54に取付けた取付調整部材53にスイッチ本体51を取付けるに際し、円筒状部57又は磁気調整部材59の先端とスイッチ移動体52との間の距離Dを予め調整した距離となるように、スイッチ本体51の円筒状部57を磁気調整部材59に挿入した後、既に述べたようにスイッチ本体を回転させて取付ける。 That is, when the switch body 51 is attached to the attachment adjustment member 53 attached to the attachment plate 54, the distance D between the tip of the cylindrical portion 57 or the magnetic adjustment member 59 and the switch moving body 52 is adjusted in advance. In addition, after inserting the cylindrical portion 57 of the switch body 51 into the magnetic adjustment member 59, the switch body is rotated and attached as described above.

距離Dを変えれば、マグネット66と磁気調整部材59との間の距離が変わるので、ホール素子61に及ぶ磁界の強さが変わり、スイッチの感度調整を行うことができる。 If the distance D is changed, the distance between the magnet 66 and the magnetic adjustment member 59 is changed, so that the strength of the magnetic field reaching the Hall element 61 is changed, and the switch sensitivity can be adjusted.

したがって、上記距離Dの予定値に対して好適なホール素子61とマグネット66を設定したうえで、磁気調整部材59を移動させることによって細かく感度調整することが可能になる。
なお、上記実施形態では、磁気感応素子をホール素子としたが、ホール素子以外の磁気抵抗素子等の磁気を検出するものであれば、適宜に磁気感応素子として利用することができる。
Therefore, it is possible to finely adjust the sensitivity by moving the magnetic adjustment member 59 after setting a suitable Hall element 61 and magnet 66 for the predetermined value of the distance D.
In the above embodiment, the magnetically sensitive element is a Hall element. However, any element that detects magnetism such as a magnetoresistive element other than the Hall element can be appropriately used as the magnetically sensitive element.
