特開２０１２－２５１５８７号公報JP 2012-251587 A

特許文献１の手動操作ユニットは、非常時に非常操作ケーブルの他端の***作部に取付けて使用される工具である。このため、通常時に工具を格納する場所を車両に設ける必要がある。また、車両のレイアウト上の理由等から工具の格納場所が非常操作ケーブルの***作部から離れている場合、作業者は工具を探す必要があり煩雑である。 The manual operation unit disclosed in Patent Literature 1 is a tool that is used by being attached to an operated portion at the other end of an emergency operation cable in an emergency. For this reason, it is necessary to provide a place in the vehicle for storing the tool during normal operation. In addition, when the tool is stored away from the operated portion of the emergency operation cable due to reasons such as the layout of the vehicle, the operator has to search for the tool, which is troublesome.

そこで本開示は、工具の格納場所が不要であり、且つ非常時に工具を探す必要がない電動パーキングブレーキの非常操作ケーブルのキャップの提供を目的とする。 SUMMARY OF THE INVENTION Accordingly, an object of the present disclosure is to provide an emergency operation cable cap for an electric parking brake that does not require a tool storage space and does not require searching for a tool in an emergency.

上記目的を達成すべく、本開示の一態様は、チューブ状のケーブル外装部材の内部をケーブル本体が挿通する非常操作ケーブルの***作部に装着されるキャップであって、キャップ本体と可動体とを備える。非常操作ケーブルの一端では、ケーブル本体の一端が電動パーキングブレーキのアクチュエータに接続され、***作部は、非常操作ケーブルの他端に設けられる。***作部は、円筒状の外装端部と係止突部とを有する。外装端部は、ケーブル外装部材の他端に設けられ、外装端部の外周面には、雄ネジが形成される。係止突部は、ケーブル本体の他端に設けられ、外装端部から突出する。外装端部に対して係止突部を回転させることにより、ケーブル本体が回転して電動パーキングブレーキが作動し又は作動が解除される。 In order to achieve the above object, one aspect of the present disclosure is a cap attached to an operated portion of an emergency operation cable having a cable main body inserted through the inside of a tubular cable armor member, the cap main body and a movable body. Prepare. At one end of the emergency operation cable, one end of the cable body is connected to the actuator of the electric parking brake, and the operated portion is provided at the other end of the emergency operation cable. The operated portion has a cylindrical exterior end portion and a locking protrusion. The armor end is provided at the other end of the cable armor member, and a male screw is formed on the outer peripheral surface of the armor end. The locking protrusion is provided at the other end of the cable body and protrudes from the exterior end. Rotating the locking projection with respect to the exterior end rotates the cable body to activate or deactivate the electric parking brake.

キャップ本体は、第１方向の一側が開口する円柱状の収容空間を、筒状の周壁部と周壁部の第１方向の他側を閉止する底壁部とが区画する有底筒形状である。周壁部の少なくとも一側の内周面には、***作部の雄ネジと螺合可能な雌ネジが形成される。キャップ本体は、一側から収容空間へ***作部の係止突部を挿入して雌ネジを雄ネジに螺合することにより、係止突部を覆った状態で***作部に装着される。 The cap body has a bottomed cylindrical shape in which a cylindrical housing space with one side open in the first direction is partitioned by a cylindrical peripheral wall portion and a bottom wall portion closing the other side of the peripheral wall portion in the first direction. . A female thread that can be screwed with the male thread of the operated portion is formed on the inner peripheral surface of at least one side of the peripheral wall portion. The cap main body is attached to the operated part in a state in which the engaging protrusion is covered by inserting the locking projection of the operated part into the accommodation space from one side and screwing the female screw into the male screw. .

可動体は、底壁部の端面に第１方向の他側から対向し、収納位置と使用位置との間を傾動するようにキャップ本体に回転自在に支持される。可動体には、使用位置で第１方向と交叉する第２方向に凹み、雌ネジと雄ネジとの螺合を解除してキャップ本体を***作部から取外した状態で、***作部の係止突部と係合可能な係合穴が設けられる。収納位置の可動体の係合穴の開口端は、底壁部の端面によって第１方向の他側から覆われる。 The movable body faces the end surface of the bottom wall portion from the other side in the first direction and is rotatably supported by the cap body so as to tilt between the storage position and the use position. The movable body is recessed in a second direction that intersects with the first direction at the use position, and is engaged with the operated part in a state in which the female screw and the male screw are disengaged and the cap main body is removed from the operated part. An engagement hole is provided that can be engaged with the stop protrusion. The open end of the engagement hole of the movable body at the retracted position is covered from the other side in the first direction by the end face of the bottom wall portion.

上記構成では、電動パーキングブレーキのアクチュエータが正常に作動する通常時には、キャップ本体の収容空間へ非常操作ケーブルの***作部の係止突部を挿入し、キャップ本体の雌ネジを***作部の雄ネジに螺合して、キャップを***作部に装着する。これにより、***作部の係止突部がキャップ本体によって覆われるので、係止突部を保護することができる。 In the above configuration, when the actuator of the electric parking brake operates normally, the locking protrusion of the operated portion of the emergency operation cable is inserted into the accommodation space of the cap body, and the female screw of the cap body is inserted into the male portion of the operated portion. Attach the cap to the operated part by screwing it onto the screw. As a result, the locking protrusion of the operated portion is covered with the cap body, so that the locking protrusion can be protected.

電動パーキングブレーキのアクチュエータが正常に作動しない非常時には、非常操作ケーブルの***作部の雄ネジとキャップ本体の雌ネジとの螺合を解除してキャップを***作部から取外し、可動体を収納位置から使用位置へ傾動させた後、キャップの可動体の係合穴を***作部の係止突部に係合する。キャップの係合穴を***作部の係止突部に係合した係合状態では、非常操作ケーブルのケーブル本体の軸方向（係止突部の突出方向、第２方向）とキャップ本体の長手方向（第１方向）とが交叉するので、作業者は、一方の手で非常操作ケーブルの外装端部を把持し、他方の手でキャップ本体を掴んで回転させる。これにより、ケーブル本体が回転して電動パーキングブレーキが作動し又は作動が解除される。 In an emergency when the actuator of the electric parking brake does not operate normally, the male screw on the operated part of the emergency operation cable and the female screw on the cap body are unscrewed, the cap is removed from the operated part, and the movable body is moved to the retracted position. After tilting from the upper position to the use position, the engaging hole of the movable body of the cap is engaged with the locking protrusion of the operated part. In the engaged state in which the engaging hole of the cap is engaged with the locking projection of the operated part, the axial direction of the cable body of the emergency operation cable (projection direction of the locking projection, second direction) and the longitudinal direction of the cap body Since the direction (first direction) intersects, the operator grasps the exterior end of the emergency operation cable with one hand and grasps and rotates the cap body with the other hand. As a result, the cable body rotates to activate or deactivate the electric parking brake.

このように、通常時に非常操作ケーブルの***作部に装着されて係止突部を保護するキャップを、非常時にケーブル本体を回転させるための工具として用いるので、部品点数を削減することができる。また、通常時の工具の格納場所が不要であり、且つ作業者は非常時に工具を探す必要がない。 In this way, the cap that is normally attached to the operated portion of the emergency operation cable and protects the locking protrusion is used as a tool for rotating the cable body in an emergency, so that the number of parts can be reduced. In addition, there is no need for a place to store tools in normal times, and workers do not need to search for tools in an emergency.

また、係合穴をキャップ本体ではなくキャップ本体に回転自在に支持される可動体に設けているので、可動体を収納位置に設定した状態でのキャップ全体の形状を、複雑ではない単純な形状に構成することができる。このため、形状が複雑なキャップを用いる場合に比べて、通常時の非常操作ケーブルの収納場所を車両側に確保し易い。 In addition, since the engaging hole is provided not in the cap body but in the movable body that is rotatably supported by the cap body, the shape of the entire cap when the movable body is set at the retracted position is a simple shape that is not complicated. can be configured to Therefore, compared to the case where a cap having a complicated shape is used, it is easier to secure a storage place for the emergency operation cable in the normal state on the vehicle side.

本開示の電動パーキングブレーキの非常操作ケーブルのキャップによれば、工具の格納場所が不要であり、且つ非常時に工具を探す必要がない。 According to the cap of the emergency operation cable of the electric parking brake of the present disclosure, there is no need to store the tool, and there is no need to search for the tool in an emergency.

以下、本発明の一実施形態について図面を参照して説明する。 An embodiment of the present invention will be described below with reference to the drawings.

電動パーキングブレーキ（図示省略）のアクチュエータ１には、図１に示すように、コントロールケーブル２の一端と非常操作ケーブル３の一端とが接続される。コントロールケーブル２の他端には、電動パーキングブレーキが接続され、アクチュエータ１によりコントロールケーブル２が引張られると電動パーキングブレーキが作動し、アクチュエータ１によりコントロールケーブル２の引張りが戻されると、電動パーキングブレーキの作動が解除される。 As shown in FIG. 1, one end of a control cable 2 and one end of an emergency operation cable 3 are connected to an actuator 1 of an electric parking brake (not shown). An electric parking brake is connected to the other end of the control cable 2. When the control cable 2 is pulled by the actuator 1, the electric parking brake operates. When the control cable 2 is released by the actuator 1, the electric parking brake is applied. Operation is canceled.

非常操作ケーブル３は、チューブ状のケーブル外装部材４と、ケーブル外装部材４の内部を挿通するケーブル本体５とから概略構成される。非常操作ケーブル３の一端では、ケーブル本体５の一端がアクチュエータ１に接続され、非常操作ケーブル３の他端には、***作部６が設けられる。***作部６は、円筒状の外装端部７と、矩形軸状の係止突部８とを有する。外装端部７は、ケーブル外装部材４の他端に設けられ、外装端部７の先端の外周面には、雄ネジ９が形成される。係止突部８は、ケーブル本体５の他端に一体的に設けられ、外装端部７から突出する。係止突部８は外装端部７に回転自在に支持され、外装端部７に対して係止突部８を回転させるとケーブル本体５が回転する。ケーブル本体５が回転することによってアクチュエータ１が操作され、コントロールケーブル２が引張られて電動パーキングブレーキが作動し、又は、コントロールケーブル２の引張りが戻されて電動パーキングブレーキの作動が解除される。従って、アクチュエータ１が故障等により作動しなくなった場合、作業者は、非常操作ケーブルの***作部６を操作する（外装端部７に対して係止突部８を手動で回転させる）ことによって、電動パーキングブレーキを作動させ、又は作動を解除することができる。 The emergency operation cable 3 is roughly composed of a tubular cable armoring member 4 and a cable main body 5 inserted through the cable armoring member 4 . One end of the cable body 5 is connected to the actuator 1 at one end of the emergency operation cable 3 , and the operated portion 6 is provided at the other end of the emergency operation cable 3 . The operated portion 6 has a cylindrical exterior end portion 7 and a rectangular shaft-shaped locking protrusion 8 . The exterior end portion 7 is provided at the other end of the cable exterior member 4 , and a male screw 9 is formed on the outer peripheral surface of the tip of the exterior end portion 7 . The locking protrusion 8 is integrally provided at the other end of the cable body 5 and protrudes from the exterior end 7 . The locking projection 8 is rotatably supported by the exterior end 7 , and the cable body 5 rotates when the locking projection 8 is rotated with respect to the exterior end 7 . By rotating the cable body 5, the actuator 1 is operated, the control cable 2 is pulled to operate the electric parking brake, or the control cable 2 is released to release the operation of the electric parking brake. Therefore, when the actuator 1 becomes inoperable due to a failure or the like, the operator operates the operated portion 6 of the emergency operation cable (manually rotates the locking protrusion 8 with respect to the exterior end portion 7). , the electric parking brake can be activated or deactivated.

図３～図５に示すように、***作部６には、キャップ１１が着脱可能に装着される。キャップ１１は、キャップ本体１２と可動体１３とを有する。 As shown in FIGS. 3 to 5, a cap 11 is detachably attached to the operated portion 6. As shown in FIGS. The cap 11 has a cap body 12 and a movable body 13 .

キャップ本体１２は、周壁部１４と底壁部１５とを一体的に有する有底筒形状であり、長手方向（第１方向）の一側が開口する円柱状の収容空間１６を区画する。周壁部１４は円筒状であり、底壁部１５は周壁部１４の長手方向の他側を閉止する。周壁部１４の少なくとも一側（開口１７側）の内周面には、***作部６の雄ネジ９と螺合可能な雌ネジ１８が形成される。キャップ１１（キャップ本体１２）は、一側の開口１７から収容空間１６へ***作部６の係止突部８を挿入して雌ネジ１８を雄ネジ９に螺合することにより、係止突部８を覆った状態で***作部６に装着される。 The cap main body 12 has a cylindrical shape with a bottom and integrally includes a peripheral wall portion 14 and a bottom wall portion 15, and defines a cylindrical housing space 16 that is open on one side in the longitudinal direction (first direction). The peripheral wall portion 14 is cylindrical, and the bottom wall portion 15 closes the other longitudinal side of the peripheral wall portion 14 . A female thread 18 that can be screwed with the male thread 9 of the operated portion 6 is formed on the inner peripheral surface of at least one side (opening 17 side) of the peripheral wall portion 14 . The cap 11 (cap main body 12) inserts the locking projection 8 of the operated portion 6 into the accommodation space 16 from the opening 17 on one side, and screws the female screw 18 into the male screw 9 to form the locking projection. It is attached to the operated portion 6 while covering the portion 8 .

キャップ本体１２の長手方向の他側の端部には、長手方向と略直交する径方向（第１方向と交叉する第２方向）に離間して相対向し、各々が長手方向に沿って延びる1対の対向壁部２０が設けられている。対向壁部２０は、底壁部１５の端面１９から一体的に延びる。 At the end on the other side of the longitudinal direction of the cap main body 12 , they are spaced apart in a radial direction substantially perpendicular to the longitudinal direction (the second direction intersecting with the first direction), and each extend along the longitudinal direction. A pair of opposing walls 20 are provided. The opposing wall portion 20 integrally extends from the end surface 19 of the bottom wall portion 15 .

可動体１３は、２つの対向壁部２０の間に配置され、底壁部１５の端面１９にキャップ本体１２の長手方向の他側から対向する。可動体１３は、収納位置（図４参照）と使用位置（図５参照）との間を傾動可能に、回転軸２１を中心として回転自在に対向壁部２０に支持される。キャップ本体１２（対向壁部２０）と可動体１３との相対回転は、可動体１３が自重によって傾動せず、作業者が所定の力で可動体１３を回すことによって傾動するように、摩擦等によって規制されている。なお、可動体１３を収納位置と使用位置とに仮保持する機構を設けてもよい。また、図示の可動体１３は円柱状であるが、可動体１３の形状はこれに限定されず、他の形状（例えば角柱状など）であってもよい。 The movable body 13 is arranged between the two opposing walls 20 and faces the end surface 19 of the bottom wall 15 from the other longitudinal side of the cap body 12 . The movable body 13 is supported by the opposing wall portion 20 so as to be tiltable between a storage position (see FIG. 4) and a use position (see FIG. 5) and to be rotatable about a rotating shaft 21. As shown in FIG. The relative rotation between the cap main body 12 (facing wall portion 20) and the movable body 13 is controlled by friction or the like so that the movable body 13 does not tilt due to its own weight, but tilts when an operator rotates the movable body 13 with a predetermined force. regulated by A mechanism for temporarily holding the movable body 13 at the storage position and the use position may be provided. Further, although the illustrated movable body 13 is cylindrical, the shape of the movable body 13 is not limited to this, and may be other shapes (for example, a prismatic shape).

可動体１３には、可動体１３を使用位置に設定した状態で、キャップ本体１２の径方向に凹む矩形状の係合穴２２が設けられる。可動体１３を収納位置に設定した状態で、係合穴２２の開口端２３は、底壁部１５の端面１９によってキャップ本体１２の長手方向の他側から覆われる。雌ネジ１８と雄ネジ９との螺合を解除してキャップ１１を***作部６から取外し、可動体１３を使用位置に設定した状態で、係合穴２２は、***作部６の係止突部８と係合可能である。係止突部８の断面形状及び係合穴２２の穴形状は矩形状に限定されず、他の形状（例えば六角形状など）であってもよい。 The movable body 13 is provided with a rectangular engagement hole 22 recessed in the radial direction of the cap main body 12 when the movable body 13 is set at the use position. The opening end 23 of the engaging hole 22 is covered with the end face 19 of the bottom wall portion 15 from the other longitudinal side of the cap body 12 when the movable body 13 is set at the retracted position. The engagement between the female screw 18 and the male screw 9 is released, the cap 11 is removed from the operated portion 6, and the movable body 13 is set to the use position. It is engageable with the protrusion 8 . The cross-sectional shape of the locking protrusion 8 and the hole shape of the engaging hole 22 are not limited to a rectangular shape, and may be other shapes (for example, a hexagonal shape).

本実施形態によれば、電動パーキングブレーキのアクチュエータ１が正常に作動する通常時には、可動体１３を収納位置に設定し、キャップ本体１２の収容空間１６へ非常操作ケーブル３の***作部６の係止突部８を挿入し、キャップ本体１２の雌ネジ１８を***作部６の雄ネジ９に螺合して、キャップ１１を***作部６に装着する。これにより、***作部６の係止突部８がキャップ本体１２によって覆われるので、係止突部８を保護することができる。 According to this embodiment, when the actuator 1 of the electric parking brake normally operates, the movable body 13 is set to the storage position, and the operated portion 6 of the emergency operation cable 3 is engaged with the storage space 16 of the cap body 12 . The locking protrusion 8 is inserted, and the female thread 18 of the cap main body 12 is screwed into the male thread 9 of the operated section 6 to attach the cap 11 to the operated section 6 . As a result, the locking protrusion 8 of the operated portion 6 is covered with the cap body 12, so that the locking protrusion 8 can be protected.

電動パーキングブレーキのアクチュエータ１が正常に作動しない非常時には、非常操作ケーブル３の***作部６の雄ネジ９とキャップ本体１２の雌ネジ１８との螺合を解除してキャップ１１を***作部６から取外し、可動体１３を収納位置から使用位置へ傾動させた後、キャップ１１の可動体１３の係合穴２２を***作部６の係止突部８に係合する。キャップ１１の係合穴２２を***作部６の係止突部８に係合した係合状態では、非常操作ケーブル３のケーブル本体５の軸方向（係止突部８の突出方向、第２方向）とキャップ本体１２の長手方向（第１方向）とが略直交するので、作業者は、一方の手で非常操作ケーブル３の外装端部７を把持し、他方の手でキャップ本体１２を掴んで回転させる。これにより、ケーブル本体５が回転して電動パーキングブレーキが作動し又は作動が解除される。 In an emergency when the electric parking brake actuator 1 does not operate normally, the male thread 9 of the operated portion 6 of the emergency operation cable 3 and the female thread 18 of the cap body 12 are unscrewed to release the cap 11 from the operated portion 6 . After tilting the movable body 13 from the storage position to the use position, the engagement hole 22 of the movable body 13 of the cap 11 is engaged with the locking protrusion 8 of the operated portion 6 . In the engaged state where the engagement hole 22 of the cap 11 is engaged with the locking projection 8 of the operated portion 6, the axial direction of the cable main body 5 of the emergency operation cable 3 (the projecting direction of the locking projection 8, the second direction) and the longitudinal direction (first direction) of the cap body 12 are substantially perpendicular to each other. grab and rotate. As a result, the cable body 5 rotates and the electric parking brake is activated or deactivated.

このように、通常時に非常操作ケーブル３の***作部６に装着されて係止突部８を保護するキャップ１１を、非常時にケーブル本体５を回転させるための工具として用いるので、部品点数を削減することができる。また、通常時の工具の格納場所が不要であり、且つ作業者は非常時に工具を探す必要がない。 In this way, the cap 11 that is normally attached to the operated portion 6 of the emergency operation cable 3 to protect the locking protrusion 8 is used as a tool for rotating the cable body 5 in an emergency, thus reducing the number of parts. can do. In addition, there is no need for a place to store tools in normal times, and workers do not need to search for tools in an emergency.

また、係合穴２２をキャップ本体１２ではなくキャップ本体１２に回転自在に支持される可動体１３に設けているので、可動体１３を収納位置に設定した状態でのキャップ１１全体の形状を、複雑ではない単純な形状に構成することができる。このため、形状が複雑なキャップを用いる場合に比べて、通常時の非常操作ケーブルの収納場所を車両側に確保し易い。 Further, since the engaging hole 22 is provided not in the cap main body 12 but in the movable body 13 rotatably supported by the cap main body 12, the shape of the entire cap 11 with the movable body 13 set at the retracted position is It can be configured into simple shapes that are not complicated. Therefore, compared to the case where a cap having a complicated shape is used, it is easier to secure a storage place for the emergency operation cable in the normal state on the vehicle side.
