Description

本発明は、ロック解除機構及び回転検出装置に関する。 The present invention relates to an unlocking mechanism and a rotation detection device.

従来、着脱作業が簡単なストッパ機構が提案されている（特許文献１を参照）。 Conventionally, a stopper mechanism that is easy to attach / detach has been proposed (see Patent Document 1).

このストッパ機構は、コード板を有する回転体に対してストッパ部材を着脱可能とし、このストッパ部材に拘束部（切欠部と規制突起）と保持部および取着部（ロック部）とを形成してあり、保持部を回転体の貫通孔に挿入すると、ロック部によって保持部が回転体に係止されると共に、拘束部によってハウジングに対する回転体の自由な回転が阻止される。ロック部から突出する駆動受が回転コネクタのロータ部材に当接して押圧されることにより、ロック部が内方へ変位して保持部と回転体の係止が自動的に解除される構成とされている。 This stopper mechanism makes it possible to attach / detach a stopper member to a rotating body having a cord plate, and a restraining portion (notch portion and regulating protrusion), a holding portion, and a mounting portion (locking portion) are formed on the stopper member. When the holding portion is inserted into the through hole of the rotating body, the holding portion is locked to the rotating body by the locking portion, and the restraining portion prevents the rotating body from freely rotating with respect to the housing. When the drive receiver protruding from the lock portion abuts on the rotor member of the rotary connector and is pressed, the lock portion is displaced inward and the lock between the holding portion and the rotating body is automatically released. ing.

特許文献１で示すような従来のストッパ機構は、組み付け後においては、ロック部が内方へ変位して保持部と回転体の係止が自動的に解除される。しかし、上記述べたように、ロック部が内方へ変位することから、特許文献１で示すような従来のストッパ機構は、板状のロック部を均一に押し当てて変位させてロック解除しなければならず、組付け性に問題があった。さらに、回転検知するためのセンサに電力を供給するため、コネクタ挿入の組付けも必要であり、組付けにかかる工数が多いという問題があった。 In the conventional stopper mechanism as shown in Patent Document 1, after assembly, the lock portion is displaced inward and the holding portion and the rotating body are automatically unlocked. However, as described above, since the lock portion is displaced inward, the conventional stopper mechanism as shown in Patent Document 1 must uniformly press and displace the plate-shaped lock portion to release the lock. There was a problem with the ease of assembly. Further, in order to supply electric power to the sensor for detecting rotation, it is necessary to assemble the connector, which causes a problem that the number of man-hours required for assembly is large.

［２］前記移動部材は回転部材である、上記［１］に記載のロック解除機構であってもよい。
［３］また、上記［２］に記載のロック解除機構と、前記回転部材の回転検出を行なう回転検出手段と、を有する回転検出装置であってもよい。 [1] In order to achieve the above object, a moving member having an engaging portion, a holding member for holding the moving member freely, a release position where the moving member is free to move, and the engaging portion are engaged. When it has an engaging member that can move between the locking positions that are combined and cannot be moved, and a connector insertion portion that allows the connector to be inserted, and the connector is attached to the connector insertion portion, the engagement member Provided is an unlocking mechanism in which the engaging member moves to the locking position when the mating member moves to the unlocking position and the connector is not attached to the connector insertion portion.
[2] The moving member may be the unlocking mechanism according to the above [1], which is a rotating member.
[3] Further, the rotation detecting device may include the unlocking mechanism according to the above [2] and the rotation detecting means for detecting the rotation of the rotating member.

Further, when the connector 400 is attached to the connector insertion portion 250, a part 460 of the connector housing 450 abuts on the end portion 330 of the main body portion 300a of the engaging member 300 and presses the connector 400. As a result, the engaging member 300 can rotate in the B direction about the rotation support portion 220.

（第２の実施の形態に係るロック解除機構１の動作）
図２（ａ）は、コネクタがコネクタ挿入部に非装着の状態の場合の図である。この状態では、係合部材３００が係止位置Ｌonへ移動した状態である。 (Operation of the unlocking mechanism 1 according to the second embodiment)
FIG. 2A is a diagram in the case where the connector is not attached to the connector insertion portion. In this state, the engaging member 300 has moved to the locking position Lon.

係合部材３００は、図２（ａ）に示すように、係止位置Ｌonにある。この状態では、係合部３１０は、図示省略する付勢力により、回転部材１００の係合部１１０と係合している。これにより、回転部材１００は、図２（ｂ）に示すＣ方向、すなわち、保持部材２００の内径部２１０で支持されて回転方向には移動できない。これにより、回転部材１００は、ロック状態とされている。 The engaging member 300 is at the locking position Lon, as shown in FIG. 2 (a). In this state, the engaging portion 310 is engaged with the engaging portion 110 of the rotating member 100 by an urging force (not shown). As a result, the rotating member 100 cannot move in the C direction shown in FIG. 2B, that is, is supported by the inner diameter portion 210 of the holding member 200 and cannot move in the rotating direction. As a result, the rotating member 100 is locked.

図２（ｂ）は、コネクタがコネクタ挿入部に装着されている場合の図である。この状態では、係合部材３００が解除位置Ｌoffへ移動した状態である。 FIG. 2B is a diagram when the connector is attached to the connector insertion portion. In this state, the engaging member 300 has moved to the release position Loff.

係合部材３００は、図２（ｂ）に示すように、コネクタ４００がコネクタ挿入部２５０に装着されることにより、本体部３００ａの端部３３０はコネクタ４００により押圧され、係合部材３００はＢ方向に回転して、解除位置Ｌoffまで移動する。この状態では、係合部３１０は、回転部材１００の係合部１１０と係合していない。これにより、回転部材１００は、図２（ｂ）に示すＣ方向、すなわち、保持部材２００の内径部２１０で支持されて回転方向に移動自由となる。これにより、回転部材１００は、ロック解除状態とされている。 In the engaging member 300, as shown in FIG. 2B, when the connector 400 is attached to the connector insertion portion 250, the end portion 330 of the main body portion 300a is pressed by the connector 400, and the engaging member 300 is B. It rotates in the direction and moves to the release position Loff. In this state, the engaging portion 310 is not engaged with the engaging portion 110 of the rotating member 100. As a result, the rotating member 100 is supported by the inner diameter portion 210 of the holding member 200 in the C direction shown in FIG. 2B, that is, is free to move in the rotating direction. As a result, the rotating member 100 is in the unlocked state.

（本発明の第３の実施の形態）
第３の実施の形態は、上記説明したロック解除機構１と、回転部材の回転検出を行なう回転検出手段と、を有する回転検出装置５００である。図３（ａ）は、回転部材を平面視した上平面図であり、図３（ｂ）は、図３（ａ）のＤ−Ｄ断面を示す断面図である。 (Third Embodiment of the present invention)
A third embodiment is a rotation detecting device 500 having the unlocking mechanism 1 described above and a rotation detecting means for detecting the rotation of the rotating member. FIG. 3A is an upper plan view of the rotating member in a plan view, and FIG. 3B is a cross-sectional view showing a DD cross section of FIG. 3A.

図３（ａ）、（ｂ）に示すように、回転検出装置５００には、回転検出手段として、回転部材１００の回転検出を行なう磁気センサ６０を備えた基板６５が装着されている。なお、回転検出手段としては、上記のものには限定されず、例えば、ロータリエンコーダ等の光学式のもの等、他の回転検出手段を用いることが可能である。 As shown in FIGS. 3A and 3B, the rotation detecting device 500 is equipped with a substrate 65 provided with a magnetic sensor 60 for detecting the rotation of the rotating member 100 as a rotation detecting means. The rotation detecting means is not limited to the above, and other rotation detecting means such as an optical type such as a rotary encoder can be used.

磁気センサ６０は、回転部材１００の回転（磁石の回転）を検出するためのもので、例えば、ＭＲ素子、ホール素子等の磁気検出素子を使用することができる。 The magnetic sensor 60 is for detecting the rotation of the rotating member 100 (rotation of the magnet), and for example, a magnetic detection element such as an MR element or a Hall element can be used.

回転部材１００に取り付けられるマグネット６３は、例えば、円板状の永久磁石であり、例えば、図３（ｂ）に示すように、板厚と直交する方向にＮ極、Ｓ極が着磁されている。このマグネット６３の磁界は、回転部材１００の回転と共に回転し、上記した磁気センサ６０により、磁界の方向変化、磁界の強度変化等が検出される。
The magnet 63 attached to the rotating member 100 is, for example, a disk-shaped permanent magnet. For example, as shown in FIG. 3B, the north and south poles are magnetized in the direction orthogonal to the plate thickness. There is. The magnetic field of the magnet 63 rotates with the rotation of the rotating member 100, and the above-mentioned magnetic sensor 60 detects a change in the direction of the magnetic field, a change in the strength of the magnetic field, and the like.

回転検出装置５００が対象機器に取り付けられ、コネクタ４００がコネクタ挿入部２５０に装着されると、回転部材１００のロックが解除される。この状態で、回転部材１００の回転と共にマグネット６３も回転し、磁気センサ６０により、磁界の方向変化、磁界の強度変化等が検出される。これにより、回転検出装置５００は、回転検出（回転角度、回転方向）が可能になる。 When the rotation detection device 500 is attached to the target device and the connector 400 is attached to the connector insertion portion 250, the rotation member 100 is unlocked. In this state, the magnet 63 also rotates with the rotation of the rotating member 100, and the magnetic sensor 60 detects a change in the direction of the magnetic field, a change in the strength of the magnetic field, and the like. As a result, the rotation detection device 500 can detect rotation (rotation angle, rotation direction).

回転検出装置５００は、組み付け前の回転部材１００の位置、また、取り外す場合の回転部材１００の位置がロック機構により規定されているので、対象機器への組み付け時において回転部材１００の位置がイニシャルポジションにある。したがって、組み付け時、取外し時において、回転部材１００の回転位置の再調整が不要である。 In the rotation detection device 500, the position of the rotating member 100 before assembly and the position of the rotating member 100 when removed are defined by the lock mechanism, so that the position of the rotating member 100 is the initial position when assembling to the target device. It is in. Therefore, it is not necessary to readjust the rotation position of the rotating member 100 at the time of assembling and disassembling.

回転検出装置５００は、車両への適用例として、ブレーキペダルの操作角度を検出するペダルセンサ等が挙げられる。 An example of application of the rotation detection device 500 to a vehicle is a pedal sensor that detects an operating angle of a brake pedal.
