Description
本発明は、ストライカと係脱する回転可能なフックと、フックの回転位置を固定及び固定解除する回転可能なポールと、を具備する車両用ロック装置に関する。
The present invention relates to a vehicle locking device including a rotatable hook that engages and disengages with a striker, and a rotatable pole that fixes and releases the rotational position of the hook.
自動車本体の背面開口部にストライカを突設し、該背面開口部を開閉するリアドアに上記ストライカと係脱するロック装置を設けた従来技術としては、例えば特許文献1に開示されたものがある。
このロック装置は、リアドアに固定した、一面が開口しかつ底壁にストライカが挿脱可能なストライカ進入溝を形成した箱形のベースプレート(支持ケース)と、ベースプレートの底壁に固定した一対の枢軸(支持軸)と、上記ストライカと非係合のアンロック位置とストライカと係合するロック位置との間を回転可能として一方の枢軸に取り付け、かつ付勢手段によってアンロック位置に向けて回転付勢されたフック(ラッチ)と、ロック位置に位置するフックと係合する係合位置とフックとの係合を解除する非係合位置との間を回転可能として他方の枢軸に取り付けたポール(ラチェット)と、ベースプレートの開口面を塞ぎ、かつ一対の枢軸の端部が嵌合する支持孔を有するカバープレート(カバー)と、を具備している。
このロック装置にはアクチュエータユニットが接続している。アクチュエータユニットは、電力によりウォームを回転させるモータと、ウォームと噛合しかつカム面を有するウォームホイルと、ウォームホイルのカム面に対して接触するカムフォロア、及び、ベースプレートとカバープレートの隙間からベースプレートの内部空間に進入してポールと対向する押圧部(出力部)を有する作動レバー(ロック解除レバー)と、を具備している。 For example, Patent Document 1 discloses a conventional technique in which a striker protrudes from a rear opening of an automobile body, and a lock device that engages and disengages the striker is provided at a rear door that opens and closes the rear opening.
This locking device has a box-shaped base plate (support case) that is fixed to the rear door and that has an opening on one side and a striker insertion groove on the bottom wall that can be inserted and removed, and a pair of pivots that are fixed to the bottom wall of the base plate. (Support shaft) is attached to one pivot so as to be rotatable between the unlocked position not engaged with the striker and the locked position engaged with the striker, and is rotated toward the unlocked position by the biasing means. A pole attached to the other pivot so as to be rotatable between a biased hook (latch) and an engagement position for engaging with a hook located at a lock position and a non-engagement position for releasing the engagement with the hook ( Ratchet) and a cover plate (cover) having a support hole that closes the opening surface of the base plate and fits the ends of a pair of pivots.
An actuator unit is connected to the lock device. The actuator unit includes a motor that rotates the worm with electric power, a worm wheel that meshes with the worm and has a cam surface, a cam follower that contacts the cam surface of the worm wheel, and a gap between the base plate and the cover plate. An operating lever (lock release lever) having a pressing portion (output portion) that enters the space and faces the pole.
このロック装置は、リアドアに固定した、一面が開口しかつ底壁にストライカが挿脱可能なストライカ進入溝を形成した箱形のベースプレート(支持ケース)と、ベースプレートの底壁に固定した一対の枢軸(支持軸)と、上記ストライカと非係合のアンロック位置とストライカと係合するロック位置との間を回転可能として一方の枢軸に取り付け、かつ付勢手段によってアンロック位置に向けて回転付勢されたフック(ラッチ)と、ロック位置に位置するフックと係合する係合位置とフックとの係合を解除する非係合位置との間を回転可能として他方の枢軸に取り付けたポール(ラチェット)と、ベースプレートの開口面を塞ぎ、かつ一対の枢軸の端部が嵌合する支持孔を有するカバープレート(カバー)と、を具備している。
このロック装置にはアクチュエータユニットが接続している。アクチュエータユニットは、電力によりウォームを回転させるモータと、ウォームと噛合しかつカム面を有するウォームホイルと、ウォームホイルのカム面に対して接触するカムフォロア、及び、ベースプレートとカバープレートの隙間からベースプレートの内部空間に進入してポールと対向する押圧部(出力部)を有する作動レバー(ロック解除レバー)と、を具備している。 For example, Patent Document 1 discloses a conventional technique in which a striker protrudes from a rear opening of an automobile body, and a lock device that engages and disengages the striker is provided at a rear door that opens and closes the rear opening.
This locking device has a box-shaped base plate (support case) that is fixed to the rear door and that has an opening on one side and a striker insertion groove on the bottom wall that can be inserted and removed, and a pair of pivots that are fixed to the bottom wall of the base plate. (Support shaft) is attached to one pivot so as to be rotatable between the unlocked position not engaged with the striker and the locked position engaged with the striker, and is rotated toward the unlocked position by the biasing means. A pole attached to the other pivot so as to be rotatable between a biased hook (latch) and an engagement position for engaging with a hook located at a lock position and a non-engagement position for releasing the engagement with the hook ( Ratchet) and a cover plate (cover) having a support hole that closes the opening surface of the base plate and fits the ends of a pair of pivots.
An actuator unit is connected to the lock device. The actuator unit includes a motor that rotates the worm with electric power, a worm wheel that meshes with the worm and has a cam surface, a cam follower that contacts the cam surface of the worm wheel, and a gap between the base plate and the cover plate. An operating lever (lock release lever) having a pressing portion (output portion) that enters the space and faces the pole.
リアドアが上記背面開口部を閉塞する全閉位置に位置すると、フックがストライカと係合しながらロック位置に位置し、かつポールが係合位置に位置してフックを該ロック位置に保持するので、ロック装置及びストライカによってリアドアが全閉位置に保持される。
この状態で、例えば自動車の車内に設けたロック解除スイッチを押すとモータに電力が供給されモータが回転するので、ウォームから回転力を受けたウォームホイルが回転し、さらにカムフォロアを通じてカム面から力を受けたロック解除レバーが回転するので、ロック解除レバーの押圧部がポールと係合してポールを非係合位置まで回転させる。すると、付勢手段によって回転付勢されているフックがアンロック位置まで回転してストライカを解放するので、リアドアが上記背面開口部を開放可能な状態になる。 When the rear door is located in the fully closed position that closes the rear opening, the hook is in the locked position while engaging the striker, and the pole is in the engaged position to hold the hook in the locked position. The rear door is held in the fully closed position by the lock device and the striker.
In this state, for example, when a lock release switch provided in an automobile is pressed, electric power is supplied to the motor and the motor rotates. Therefore, the worm wheel that receives the rotational force from the worm rotates, and further force is applied from the cam surface through the cam follower. Since the received lock release lever rotates, the pressing portion of the lock release lever engages with the pole to rotate the pole to the non-engagement position. Then, the hook that is urged to rotate by the urging means rotates to the unlock position and releases the striker, so that the rear door can open the back opening.

上記ロック装置のベースプレートには一対の取付片が突設してあり、カバープレートには各取付片とそれぞれ重なる一対の耳片が突設してある。そしてリアドアの固定部材及び取付片に形成したボルト挿通孔を挿通するボルトを耳片に形成したねじ孔に螺合することにより、ベースプレート及びカバープレートをリアドアに固定している。
しかし、取付片と耳片を重ねた分だけロック装置の厚みが大きくなるので、これに合わせてリアドアの厚みを大きくしなければならない。
またカバープレートに一対の耳片を設けているので、カバープレートを成形するためには多くの材料が必要となる。そのため高コストであり、かつ重量が重くなってしまう。 A pair of mounting pieces project from the base plate of the lock device, and a pair of ear pieces projecting from the mounting pieces project from the cover plate. Then, the base plate and the cover plate are fixed to the rear door by screwing a bolt that passes through a bolt insertion hole formed in the fixing member and the mounting piece of the rear door into a screw hole formed in the ear piece.
However, since the thickness of the locking device is increased by the amount of the mounting piece and the ear piece overlapped, the thickness of the rear door must be increased accordingly.
In addition, since a pair of ear pieces are provided on the cover plate, many materials are required to form the cover plate. Therefore, the cost is high and the weight is increased.

In addition, since a pair of ear pieces are provided on the cover plate, many materials are required to form the cover plate. Therefore, the cost is high and the weight is increased.
さらにベースプレートとカバープレートは、カバープレートの本体部(一対の耳片の間に位置する部分)をベースプレートの内部に位置させてベースプレートの一対の側壁の内面に接触させた上で、ベースプレートに突設した一対の凸部をカバープレートに形成した一対の位置決め孔に嵌合し、かつ、取付片と耳片をボルトで固定することにより、互いを位置決めしている。そのため、凸部、位置決め孔、取付片のボルト挿通孔、及び、耳片のねじ孔の形成位置の少なくと一つが設計位置からずれると、ベースプレートとカバープレートの相対位置が設計位置からずれてしまい、その結果、一端がカバープレートの支持孔に嵌合する一対の枢軸が傾いてしまうので、フックやポールの動作が不円滑になってしまう。しかし凸部、位置決め孔、取付片のボルト挿通孔、及び、耳片のねじ孔のすべての形成位置が設計位置と一致するようにベースプレート及びカバープレートを成形するのは容易でない。
また、ベースプレートとカバープレートを組み付けるときには、凸部と位置決め孔の位置、及び、取付片のボルト挿通孔と耳片のねじ孔の位置を合わせなければならないので、ベースプレートとカバープレートの組付作業は容易でない。 Furthermore, the base plate and the cover plate protrude from the base plate after the main body of the cover plate (the part located between the pair of ear pieces) is positioned inside the base plate and brought into contact with the inner surfaces of the pair of side walls of the base plate. The pair of convex portions are fitted into a pair of positioning holes formed in the cover plate, and the attachment piece and the ear piece are fixed with bolts to position each other. For this reason, if at least one of the formation positions of the convex portion, positioning hole, bolt insertion hole of the mounting piece, and screw hole of the ear piece is displaced from the design position, the relative position of the base plate and the cover plate is displaced from the design position. As a result, the pair of pivots whose one ends are fitted into the support holes of the cover plate are inclined, so that the operation of the hooks and poles becomes unsmooth. However, it is not easy to mold the base plate and the cover plate so that all the formation positions of the convex portion, the positioning hole, the bolt insertion hole of the mounting piece, and the screw hole of the ear piece coincide with the design position.
Also, when assembling the base plate and the cover plate, the position of the convex portion and the positioning hole, and the position of the bolt insertion hole of the mounting piece and the screw hole of the ear piece must be matched. Not easy.
また、ベースプレートとカバープレートを組み付けるときには、凸部と位置決め孔の位置、及び、取付片のボルト挿通孔と耳片のねじ孔の位置を合わせなければならないので、ベースプレートとカバープレートの組付作業は容易でない。 Furthermore, the base plate and the cover plate protrude from the base plate after the main body of the cover plate (the part located between the pair of ear pieces) is positioned inside the base plate and brought into contact with the inner surfaces of the pair of side walls of the base plate.

また、支持ケースとカバーを組み付けるときには、カバーの側面に形成した一対の位置規制面を支持ケースの一対の側壁の内面と対向させた上で、位置決め用凹部に係止片を嵌合させるだけでよいので、支持ケースとカバーの組付作業を容易に行うことが可能である。 In the vehicle locking device of the present invention, the cover is not overlapped with the fixing portion of the support case with respect to the vehicle main body or the door, and the locking piece of the cover is fitted into the positioning recess of the support case, and the side surface of the cover Since the (position regulating surface) is opposed to the inner surfaces of the pair of side walls, the overall thickness can be reduced.

請求の範囲第2項記載の発明によれば、係止片の一部である対向部と側壁が一対の係止片を結ぶ方向の位置規制を行うので、当該方向の位置決めがより確実になる。
According to the second aspect of the present invention, since the opposing portion which is a part of the locking piece and the side wall perform position regulation in the direction connecting the pair of locking pieces, positioning in the direction becomes more reliable. .
位置決め用凹部の底面の両端部を角形のコーナー部として正確に加工するのは容易でないので、角形のコーナー部として加工すると位置決め用凹部の底面側の幅が側壁の先端面側の幅より狭くなるおそれがある。しかし請求の範囲第3、4項記載の発明によれば、位置決め用凹部のすべての深さ方向位置における幅を確実に同一にできるので、係止片を確実に嵌合できる。
Since it is not easy to accurately process both ends of the bottom surface of the positioning concave portion as a square corner portion, the width of the bottom surface side of the positioning concave portion becomes narrower than the width of the front end surface side of the side wall when processed as a square corner portion. There is a fear. However, according to the third and fourth aspects of the invention, the widths of all the positioning recesses in the depth direction can be made the same, so that the locking pieces can be fitted securely.
請求の範囲第5~8項記載の発明によれば、係止片の幅を長手方向のいずれにおいても同じ寸法にできるので(基端側の幅が先端側より大きくなることがないので)、係止片を位置決め用凹部に確実に嵌合できる。
According to the inventions of claims 5 to 8, since the width of the locking piece can be made the same in any of the longitudinal directions (because the width on the base end side does not become larger than the tip end side), The locking piece can be reliably fitted into the positioning recess.
以下、添付図面を参照しながら本発明の一実施形態について説明する。なお、本実施形態の説明中の方向は図中に記載した矢線方向を基準とする。

In addition, the direction in description of this embodiment is based on the arrow line direction described in the figure.
Arear opening 11 is formed on the rear surface of the vehicle body of the automobile 10, and the upper edge of the back door 12 having the same shape as the rear opening 11 extends in the left-right direction at the upper edge of the rear opening 11. It is attached so as to be rotatable around the rotation axis. The back door 12 is between a fully closed position (a position indicated by a solid line in FIG. 1) that completely closes the back opening 11 and a fully open position (a position indicated by an imaginary line in FIG. 1) that is substantially horizontal and opens the back opening 11. Can be rotated. As shown in FIG. 1, a metal striker 15 protrudes upward at the bottom of the rear opening 11. Furthermore, a lock device 20 that can be engaged with and disengaged from the striker 15 is provided at a portion that forms the bottom surface of the back door 12 when the back door 12 is in the fully closed position.
自動車10の車両本体の背面には背面開口部11が形成してあり、背面開口部11の上縁部には背面開口部11と同じ形状であるバックドア12の上縁部が左右方向に延びる回転軸回りに回転自在として取り付けてある。バックドア12は背面開口部11を完全に閉じる全閉位置(図1の実線の位置)と、略水平状態となり背面開口部11を開放する全開位置(図1の仮想線の位置)との間を回転可能である。図1に示すように、背面開口部11の底部には金属製のストライカ15が上向きに突設してある。さらに、バックドア12が全閉位置に位置するときにバックドア12の底面をなす部分には、ストライカ15と係脱可能なロック装置20が設けてある。 Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

続いてロック装置20の構造について詳しく説明する。なお、ロック装置20を説明するときの上下方向及び前後方向は、バックドア12が全閉位置に位置するときの方向である。
図2から図8に示すように、ロック装置20はロックユニット25とアクチュエータユニット80を具備している。
ロックユニット25はバックドア12が全閉位置に位置するときに略水平方向に延在するユニットである。金属製の支持ケース26は、その中央部に凹設した収納凹部27と、バックドア12に固定するための左右一対の取付片28とを備えたプレス成形品である。収納凹部27の後部は開放しており、かつ収納凹部27の底壁26aには前端から後方に向かって延びるストライカ進入溝29が形成してある。また、収納凹部27の底壁26aには曲線形状をなす曲線状突条32が突設してある。
底壁26aの両側縁部に立設した底壁26aに対して略直交する左右一対の側壁26bの上縁部には位置決め用凹部31が凹設してある。図3及び図5に示すように、位置決め用凹部31の下縁部の前後両端部には側面視で半円形をなす溝部31aが、該下縁部の中央部よりも低い位置まで凹設してある。位置決め用凹部31の下縁部の前後両端部をプレス成形により角形のコーナー部として正確に加工するのは容易でないので(該コーナー部がR形状になり易いので)、角形のコーナー部として加工しようとすると位置決め用凹部31の下部の前後幅が上部の前後幅より狭くなるおそれがある。しかし、このような溝部31aを形成すれば、位置決め用凹部31のすべての上下位置における前後幅を確実に同一にできる。 Next, the structure of thelock device 20 will be described in detail. In addition, the vertical direction and the front-rear direction when describing the locking device 20 are directions when the back door 12 is located at the fully closed position.
As shown in FIGS. 2 to 8, thelock device 20 includes a lock unit 25 and an actuator unit 80.
Thelock unit 25 is a unit that extends in a substantially horizontal direction when the back door 12 is located at the fully closed position. The metal support case 26 is a press-molded product that includes a storage recess 27 that is recessed in the center thereof, and a pair of left and right attachment pieces 28 that are fixed to the back door 12. The rear portion of the storage recess 27 is open, and a striker entry groove 29 extending rearward from the front end is formed in the bottom wall 26a of the storage recess 27. In addition, a curved ridge 32 having a curved shape projects from the bottom wall 26 a of the storage recess 27.
Apositioning recess 31 is provided in the upper edge of the pair of left and right side walls 26b that are substantially orthogonal to the bottom wall 26a provided upright on both side edges of the bottom wall 26a. As shown in FIGS. 3 and 5, groove portions 31 a having a semicircular shape in a side view are recessed at the front and rear end portions of the lower edge portion of the positioning recess portion 31 so as to be lower than the center portion of the lower edge portion. It is. Since it is not easy to accurately process the front and rear ends of the lower edge of the positioning recess 31 by press molding as a rectangular corner (since the corner tends to be rounded), let's process it as a rectangular corner. Then, the front-rear width of the lower portion of the positioning recess 31 may be narrower than the front-rear width of the upper portion. However, if such a groove portion 31a is formed, the front-rear width in all the vertical positions of the positioning recess 31 can be reliably made the same.

また、バネ支持部材52の嵌合保持溝54には硬質ゴム製の押さえ部材67が回転規制された状態で嵌合している。押さえ部材67の左側面から突出する押さえ用突部68は切欠63を通ってバネ収納空間55内に位置しており、押さえ用突部68の下面は被押圧突起50の上端面に接触している。 Thehook 35 and the pole 45 are located in the lower half of the storage recess 27, and a synthetic resin spring support member 52 having a planar shape substantially the same as the storage recess 27 is stored in the upper half of the storage recess 27. It is.
Astriker entry groove 53 extending rearward is recessed in the front edge of the spring support member 52, and a fitting holding groove 54 communicating with the rear part of the striker entry groove 53 is formed in the center of the spring support member 52. The spring support member 52 is formed as a through-hole penetrating in the vertical direction. The spring support member 52 is formed with a pair of left and right spring storage spaces 55 and 56 which are separated from the striker entry groove 53 and the fitting holding groove 54 by a wall. A cylindrical rotation support cylinder 57 having upper and lower ends opened is provided on the bottom surface of the left spring storage space 55, and a cylindrical rotation support cylinder 58 having upper and lower ends opened on the bottom surface of the right spring storage space 56. It is provided. An arc groove 60 centering on the rotation support cylinder 57 is formed as a through groove on the bottom surface of the spring storage space 55, and an arc groove 61 centering on the rotation support cylinder 58 is formed on the bottom surface of the spring storage space 56. It is formed as. Further, an insertion hole 62 penetrating the spring support member 52 in the vertical direction is formed at the rear end portion of the spring support member 52, and a notch 63 is formed at the upper end of the wall partitioning the fitting holding groove 54 and the spring storage space 55. It is formed.
When thespring support member 52 is stored in the upper half of the storage recess 27, the spring support member 52 cannot rotate with respect to the storage recess 27 (around the vertical axis), and the lower surface of the spring support member 52 is the upper surface of the hook 35.

On the other hand, a torsion coil spring 65 is housed in the spring housing space 55, and a winding portion of the torsion coil spring 65 is positioned around the rotation support cylinder 57. Since one end of the torsion coil spring 64 is engaged with the spring support member 52 and the other end of the torsion coil spring 64 is engaged with the spring hooking projection 40 of the hook 35, the hook 35 is always driven by the biasing force of the torsion coil spring 64. It is urged to rotate toward the unlock position. On the other hand, one end of the torsion coil spring 65 is engaged with the spring support member 52, and the other end of the torsion coil spring 65 is engaged with the pressed protrusion 50 of the pole 45. Thus, the rotation bias is always applied to the engagement position side.
Further, a holdingmember 67 made of hard rubber is fitted in the fitting holding groove 54 of the spring support member 52 in a state where the rotation is restricted. The pressing protrusion 68 protruding from the left side surface of the pressing member 67 is positioned in the spring housing space 55 through the notch 63, and the lower surface of the pressing protrusion 68 is in contact with the upper end surface of the pressed protrusion 50.

バネ支持部材52の前縁部には後方に向かって延びるストライカ進入溝53が凹設してあり、バネ支持部材52の中央部にはストライカ進入溝53の後部と連通する嵌合保持溝54が、バネ支持部材52を上下方向に貫通する貫通孔として形成してある。バネ支持部材52には壁によってストライカ進入溝53及び嵌合保持溝54と区切られた左右一対のバネ収納空間55、56が形成してある。左側のバネ収納空間55の底面には上下両端が開口する円筒状の回転支持筒57が設けてあり、右側のバネ収納空間56の底面には上下両端が開口する円筒状の回転支持筒58が設けてある。バネ収納空間55の底面には回転支持筒57を中心とする円弧溝60が貫通溝として形成してあり、バネ収納空間56の底面には回転支持筒58を中心とする円弧溝61が貫通溝として形成してある。さらにバネ支持部材52の後端部にはバネ支持部材52を上下方向に貫通する挿通孔62が形成してあり、嵌合保持溝54とバネ収納空間55を仕切る壁の上端には切欠63が形成してある。
収納凹部27の上半部にバネ支持部材52を収納すると、バネ支持部材52は収納凹部27に対して(上下方向の軸回りに)回転不能となり、バネ支持部材52の下面がフック35の上面とポール45の上面に接触する。さらに、フック支持軸34とポール支持軸42の上部が回転支持筒58と回転支持筒57にそれぞれ挿入し、バネ掛け突起40と被押圧突起50が円弧溝61と円弧溝60にそれぞれ相対移動可能に挿入する。
バネ収納空間56には捻りコイルバネ64が収納してあり、捻りコイルバネ64の巻回部が回転支持筒58の周囲に位置している。一方、バネ収納空間55には捻りコイルバネ65が収納してあり、捻りコイルバネ65の巻回部が回転支持筒57の周囲に位置している。捻りコイルバネ64の一端はバネ支持部材52に係止してあり、捻りコイルバネ64の他端はフック35のバネ掛け突起40に係止してあるので、フック35は捻りコイルバネ64の付勢力により常にアンロック位置側に回転付勢されている。一方、捻りコイルバネ65の一端はバネ支持部材52に係止してあり、捻りコイルバネ65の他端はポール45の被押圧突起50に係止してあるので、ポール45は捻りコイルバネ65の付勢力により常に係合位置側に回転付勢されている。
また、バネ支持部材52の嵌合保持溝54には硬質ゴム製の押さえ部材67が回転規制された状態で嵌合している。押さえ部材67の左側面から突出する押さえ用突部68は切欠63を通ってバネ収納空間55内に位置しており、押さえ用突部68の下面は被押圧突起50の上端面に接触している。 The

支持ケース26の上面には金属板のプレス成形品である上部カバー(カバー)70が被せてある。上部カバー70の前縁部には後方に向かって延びるストライカ進入溝71が凹設してある。さらに、上部カバー70の後部には傾斜接続片72が形成してあり、上部カバー70の左右両側部には左右の位置決め用凹部31にそれぞれ係合する断面略L字形の係止片73が突設してある。係止片73は左右方向に延びる嵌合部74と、嵌合部74の先端から下方に延びる対向部75とを具備している。図3に示すように上部カバー70の側縁部には、嵌合部74の基端に連なりかつ平面視で半円形をなす溝部70aが形成してある。この溝部70aの技術的意義は溝部31aと同様である。即ち、仮にこの溝部70aを形成しない場合はプレス成形完了時に嵌合部74の基端側の幅(前後寸法)が先端側に比べて大きくなる(嵌合部74の基端と上部カバー70の側縁部の接続部がR形状になる)おそれがあるが、溝部70aを形成すれば嵌合部74の幅を左右方向のいずれにおいても確実に同一にできる。また、ストライカ進入溝71の両側には左右一対の支持孔76が貫通孔として形成してある。また上部カバー70の傾斜接続片72に接続する部分の両側面は、左右の側壁26bの内側面に当接する位置規制面77を構成している。
係止片73の嵌合部74の前後幅は位置決め用凹部31と略同一(僅かに短い)である。そして、位置決め用凹部31の下縁部の前後両端部に半円形の溝部31aを形成することにより、位置決め用凹部31のすべての上下位置における前後幅を同一にし、かつ上部カバー70に溝部70aを形成することにより嵌合部74のすべての左右位置における前後幅を同一にしているので、左右の係止片73の嵌合部74は左右の位置決め用凹部31に円滑に係合でき、係合させると嵌合部74の前後両面と位置決め用凹部31の前後両面との間には微小クリアランスが形成される。さらに一対の対向部75と左右の側壁26bが微小クリアランスを形成しながら左右方向に対向する。そのため、上部カバー70を支持ケース26に被せると上部カバー70は支持ケース26に対して前後及び左右に殆ど移動不能となり、支持ケース26に対して位置決めされる。さらに上部カバー70を支持ケース26に被せると、フック支持軸34のかしめ部34bとポール支持軸42のかしめ部42bが対応する支持孔76にそれぞれ嵌合し、かつ上部カバー70の下面が押さえ部材67の上面に接触する。また、平面視において傾斜接続片72は挿通孔62より前方に位置するので、上部カバー70を支持ケース26に被せても挿通孔62は上方に露出する。さらに、フック支持軸34のかしめ部34bとポール支持軸42のかしめ部42bを対応する支持孔76に挿入した後に支持孔76の周縁部に対してかしめて(図示略)固定しているので、上部カバー70が支持ケース26から脱落することはない。 The upper surface of thesupport case 26 is covered with an upper cover (cover) 70 which is a press-formed product of a metal plate. A striker entry groove 71 extending rearward is recessed in the front edge of the upper cover 70. Further, inclined connecting pieces 72 are formed at the rear part of the upper cover 70, and locking pieces 73 having a substantially L-shaped cross section that respectively engage with the left and right positioning recesses 31 protrude from the left and right sides of the upper cover 70. It is set up. The locking piece 73 includes a fitting portion 74 extending in the left-right direction and a facing portion 75 extending downward from the tip of the fitting portion 74. As shown in FIG. 3, a groove portion 70 a that is continuous with the base end of the fitting portion 74 and has a semicircular shape in plan view is formed on the side edge portion of the upper cover 70. The technical significance of the groove 70a is the same as that of the groove 31a. That is, if this groove 70a is not formed, the width (front-rear dimension) of the fitting portion 74 is larger than the tip side when the press molding is completed (the proximal end of the fitting portion 74 and the upper cover 70). However, if the groove portion 70a is formed, the width of the fitting portion 74 can be reliably made the same in both the left and right directions. A pair of left and right support holes 76 are formed as through holes on both sides of the striker entry groove 71. Further, both side surfaces of a portion of the upper cover 70 connected to the inclined connection piece 72 constitute a position restricting surface 77 that abuts against the inner surface of the left and right side walls 26b.
The front-rear width of thefitting portion 74 of the locking piece 73 is substantially the same (slightly shorter) as the positioning recess 31. Then, by forming semicircular groove portions 31 a at both front and rear end portions of the lower edge portion of the positioning recess 31, the front and rear widths at all the vertical positions of the positioning recess 31 are made the same, and the groove portion 70 a is formed in the upper cover 70. Since the front and rear widths in all the left and right positions of the fitting part 74 are made the same by forming, the fitting parts 74 of the left and right locking pieces 73 can be smoothly engaged with the left and right positioning recesses 31, As a result, a minute clearance is formed between the front and rear surfaces of the fitting portion 74 and the front and rear surfaces of the positioning recess 31. Further, the pair of facing portions 75 and the left and right side walls 26b face in the left-right direction while forming a minute clearance. Therefore, when the upper cover 70 is put on the support case 26, the upper cover 70 becomes almost immovable forward and backward and left and right with respect to the support case 26 and is positioned with respect to the support case 26. Further, when the upper cover 70 is put on the support case 26, the caulking portion 34b of the hook support shaft 34 and the caulking portion 42b of the pole support shaft 42 are fitted into the corresponding support holes 76, respectively, and the lower surface of the upper cover 70 is the pressing member. It contacts the upper surface of 67. In addition, since the inclined connection piece 72 is positioned in front of the insertion hole 62 in plan view, the insertion hole 62 is exposed upward even when the upper cover 70 is put on the support case 26. Further, since the caulking portion 34b of the hook support shaft 34 and the caulking portion 42b of the pole support shaft 42 are inserted into the corresponding support holes 76 and then caulked (not shown) to the peripheral portion of the support hole 76, they are fixed. The upper cover 70 does not fall off from the support case 26.
係止片73の嵌合部74の前後幅は位置決め用凹部31と略同一(僅かに短い)である。そして、位置決め用凹部31の下縁部の前後両端部に半円形の溝部31aを形成することにより、位置決め用凹部31のすべての上下位置における前後幅を同一にし、かつ上部カバー70に溝部70aを形成することにより嵌合部74のすべての左右位置における前後幅を同一にしているので、左右の係止片73の嵌合部74は左右の位置決め用凹部31に円滑に係合でき、係合させると嵌合部74の前後両面と位置決め用凹部31の前後両面との間には微小クリアランスが形成される。さらに一対の対向部75と左右の側壁26bが微小クリアランスを形成しながら左右方向に対向する。そのため、上部カバー70を支持ケース26に被せると上部カバー70は支持ケース26に対して前後及び左右に殆ど移動不能となり、支持ケース26に対して位置決めされる。さらに上部カバー70を支持ケース26に被せると、フック支持軸34のかしめ部34bとポール支持軸42のかしめ部42bが対応する支持孔76にそれぞれ嵌合し、かつ上部カバー70の下面が押さえ部材67の上面に接触する。また、平面視において傾斜接続片72は挿通孔62より前方に位置するので、上部カバー70を支持ケース26に被せても挿通孔62は上方に露出する。さらに、フック支持軸34のかしめ部34bとポール支持軸42のかしめ部42bを対応する支持孔76に挿入した後に支持孔76の周縁部に対してかしめて(図示略)固定しているので、上部カバー70が支持ケース26から脱落することはない。 The upper surface of the

アクチュエータユニット80の後部ケース81には、その後面及び下面が開放する収納凹部82が形成してある。さらに収納凹部82には、後部ケース81の周縁部の壁や収納凹部82内部に設けた壁等によって仕切られた正面視略矩形のモータ収納空間83と正面視略円形のウォームホイル収納空間84とが形成してあり、モータ収納空間83とウォームホイル収納空間84の間には両者を仕切り、かつ軸支用凹部86を有する仕切り壁85が突設してある。ウォームホイル収納空間84の底面(前面)には円形の支持台座88が前向きに突設してあり、支持台座88には前面が開口する円筒形状の回転支持筒89と、回転支持筒89を中心とする円弧形状のバネ支持突条90とが突設してある。さらに、収納凹部82の底面には回転支持軸92と雌ネジ孔93と支持用凹部94が形成してある。
さらに収納凹部82の底面の上部には回転支持筒89を略中心とする円弧形状の保持用突条95が突設してある。 Theactuator unit 80 is a unit that is substantially orthogonal to the lock unit 25 and extends substantially in the vertical direction when the back door 12 is located at the fully closed position.
Therear case 81 of the actuator unit 80 is formed with a storage recess 82 whose rear surface and lower surface are open.

モータ収納空間83にはモータ(アクチュエータ)97が嵌合(収納)してある。モータ97の左下側の端面には左下側に向かって直線的に延び、その軸線周りに回転する出力軸98が突設してある。出力軸98は仕切り壁85の軸支用凹部86を通ってウォームホイル収納空間84内に位置しており、その先端部は支持用凹部94によって回転可能に支持されている。出力軸98のウォームホイル収納空間84内に位置する部分の周面には、出力軸98と平行なウォーム99が一体的に形成してある。モータ97は図示を省略した電源と接続しており、自動車10の車内の運転パネルに設けたロック解除スイッチS(図1参照)を押すと、該電源から電力を受けたモータ97が所定角度だけ正転するので、出力軸98及びウォーム99が一方向に特定の回転角度だけ正転する。
ウォームホイル収納空間84に形成した支持台座88には、バネ支持突条90の外周側に位置する態様でコイルバネ100が載置してある。コイルバネ100の一方の端部は支持台座88上に形成した係止突部(図示略)に係止してある。
回転支持筒89には回転支持軸92と略平行な回転中心軸102の後端部が嵌合固定してあり、回転中心軸102の前部には、合成樹脂製であるウォームホイル104の中心部に形成した貫通支持孔105が相対回転可能に嵌合している。ウォームホイル104の後面の円形をなす周縁部の内周側はコイルバネ100を受け入れるための凹部となっており(図10参照)、該凹部の底面(前面)には略円弧状をなし、かつコイルバネ100に相対回転可能に接触する円弧状突部106が突設してある(図2及び図10参照)。また、コイルバネ100の他方の端部はウォームホイル104の該凹部に形成した係止突部に係止してある。図2等に示すように、ウォームホイル104の前面にも略円形の前側凹部108が形成してある。前側凹部108の底面(後面)には貫通支持孔105の周囲に位置するカム部109が突設してあり、カム部109の周面は貫通支持孔105からの径方向距離がその周方向位置に応じて変化するカム面110となっている。さらに前側凹部108の底面には、後述するカムフォロア119の前側凹部108内での回転範囲を規制するための第1ストッパ111と第1ストッパ1第2ストッパ112が突設してある。
回転中心軸102を介してウォームホイル104をウォームホイル収納空間84に装着すると、ウォームホイル104の周面に形成した歯部(図示略)がウォーム99と噛合する。ウォームホイル104はウォーム99から回転力を受けないときは、コイルバネ100の回転付勢力によって図6~図8に示す初期位置に保持されるが、ロック解除スイッチSを押すことによりウォーム99が上記一方向に正転すると、コイルバネ100の付勢力に抗して図9に示す作動位置まで回転する。 A motor (actuator) 97 is fitted (stored) in themotor storage space 83. An output shaft 98 that protrudes linearly toward the lower left side and rotates around its axis projects from the lower left end surface of the motor 97. The output shaft 98 is located in the worm wheel storage space 84 through the shaft support recess 86 of the partition wall 85, and its tip end portion is rotatably supported by the support recess 94. A worm 99 parallel to the output shaft 98 is integrally formed on a peripheral surface of a portion of the output shaft 98 located in the worm wheel storage space 84. The motor 97 is connected to a power source (not shown), and when a lock release switch S (see FIG. 1) provided on the driving panel in the vehicle 10 is pressed, the motor 97 that receives power from the power source has a predetermined angle. Since it rotates forward, the output shaft 98 and the worm 99 rotate forward by a specific rotation angle in one direction.
Acoil spring 100 is placed on the support base 88 formed in the worm wheel storage space 84 in a manner located on the outer peripheral side of the spring support protrusion 90. One end of the coil spring 100 is locked to a locking projection (not shown) formed on the support base 88.
Therotation support cylinder 89 is fitted and fixed to the rear end portion of the rotation center shaft 102 substantially parallel to the rotation support shaft 92, and the center of the worm wheel 104 made of synthetic resin is located at the front portion of the rotation center shaft 102. A through-supporting hole 105 formed in the portion is fitted so as to be relatively rotatable. The inner peripheral side of the circular peripheral portion of the rear surface of the worm wheel 104 is a recess for receiving the coil spring 100 (see FIG. 10), and the bottom surface (front surface) of the recess has a substantially arc shape, and the coil spring An arc-shaped protrusion 106 that is in contact with 100 is rotatably provided (see FIGS. 2 and 10). The other end of the coil spring 100 is locked to a locking protrusion formed in the recess of the worm wheel 104. As shown in FIG. 2 and the like, a substantially circular front recess 108 is also formed on the front surface of the worm wheel 104. A cam portion 109 located around the through support hole 105 projects from the bottom surface (rear surface) of the front recess 108, and the circumferential distance of the cam portion 109 from the through support hole 105 is the circumferential position. The cam surface 110 changes in accordance with the above. Further, a first stopper 111 and a first stopper 1 and a second stopper 112 for restricting the rotation range of the cam follower 119 (described later) within the front concave portion 108 project from the bottom surface of the front concave portion 108.
When theworm wheel 104 is mounted in the worm wheel storage space 84 via the rotation center shaft 102, teeth (not shown) formed on the peripheral surface of the worm wheel 104 mesh with the worm 99. When the worm wheel 104 receives no rotational force from the worm 99, the worm 99 is held at the initial position shown in FIGS. 6 to 8 by the rotational biasing force of the coil spring 100. When it rotates forward in the direction, it rotates to the operating position shown in FIG. 9 against the urging force of the coil spring 100.
ウォームホイル収納空間84に形成した支持台座88には、バネ支持突条90の外周側に位置する態様でコイルバネ100が載置してある。コイルバネ100の一方の端部は支持台座88上に形成した係止突部(図示略)に係止してある。
回転支持筒89には回転支持軸92と略平行な回転中心軸102の後端部が嵌合固定してあり、回転中心軸102の前部には、合成樹脂製であるウォームホイル104の中心部に形成した貫通支持孔105が相対回転可能に嵌合している。ウォームホイル104の後面の円形をなす周縁部の内周側はコイルバネ100を受け入れるための凹部となっており(図10参照)、該凹部の底面(前面)には略円弧状をなし、かつコイルバネ100に相対回転可能に接触する円弧状突部106が突設してある(図2及び図10参照)。また、コイルバネ100の他方の端部はウォームホイル104の該凹部に形成した係止突部に係止してある。図2等に示すように、ウォームホイル104の前面にも略円形の前側凹部108が形成してある。前側凹部108の底面(後面)には貫通支持孔105の周囲に位置するカム部109が突設してあり、カム部109の周面は貫通支持孔105からの径方向距離がその周方向位置に応じて変化するカム面110となっている。さらに前側凹部108の底面には、後述するカムフォロア119の前側凹部108内での回転範囲を規制するための第1ストッパ111と第1ストッパ1第2ストッパ112が突設してある。
回転中心軸102を介してウォームホイル104をウォームホイル収納空間84に装着すると、ウォームホイル104の周面に形成した歯部(図示略)がウォーム99と噛合する。ウォームホイル104はウォーム99から回転力を受けないときは、コイルバネ100の回転付勢力によって図6~図8に示す初期位置に保持されるが、ロック解除スイッチSを押すことによりウォーム99が上記一方向に正転すると、コイルバネ100の付勢力に抗して図9に示す作動位置まで回転する。 A motor (actuator) 97 is fitted (stored) in the

後部ケース81の回転支持軸92には、金属からなる薄板状の棒状部材であるロック解除レバー115に形成した回転支持孔116が嵌合している。ロック解除レバー115は回転支持軸92によって支持されることにより、回転支持軸92の軸線に対して直交する平面上を後部ケース81に対して回転可能である。ロック解除レバー115の下端部には押圧部117が突設してある。回転支持孔116より上側の部分は全体として略直線状の跨ぎ部118を構成しており、跨ぎ部118の中間部にはカムフォロア119が突設してある。さらに跨ぎ部118の先端部(上端部)には被押圧突起120が上向きに突設してある。
回転支持孔116を回転支持軸92に嵌合することによりロック解除レバー115を後部ケース81に装着すると、図5~図10に示すようにカムフォロア119はウォームホイル104の前側凹部108内に位置する。さらに跨ぎ部118がウォームホイル104の直前に位置する(ウォームホイル104と前後方向に対向する)とともにウォームホイル104を上方に跨ぎ、跨ぎ部118の後面の先端部近傍が保持用突条95の前面によって摺動可能に支持される(図10参照)。
後部ケース81の前面には、正面形状が後部ケース81と略同一である前部カバー122が被せてある。図示するように回転支持軸92の後部には、ロック解除レバー115と前部カバー122の間に位置する捻りコイルバネ125の巻回部が取り付けてある。捻りコイルバネ125の一端はロック解除レバー115に係止してあり、他端は前部カバー122の後面に形成した係止突起(図示略)に係止してある。このようにロック解除レバー115は捻りコイルバネ125から図6~図9の反時計方向の回転付勢力を受けているため、カムフォロア119はカム部109のカム面110に常に(回転中心軸102に対して略直交する方向に)接触する。従って、ロック解除スイッチSを押さない(モータ97が非作動状態にある)ことによりウォームホイル104が初期位置に位置するとき、ロック解除レバー115は図6~図8に示すロック許容位置に位置し、上記ロック解除スイッチを押す(モータ97が正転する)ことによりウォームホイル104が作動位置まで回転すると、カムフォロア119がカム面110から回転力を受けることにより、ロック解除レバー115は捻りコイルバネ125の回転付勢力に抗して図9に示すロック解除位置まで回転する。ロック解除レバー115がロック解除位置まで移動すると、上記電源からモータ97への給電が遮断されるのでモータ97は停止する。すると、捻りコイルバネ125の付勢力によりロック解除レバー115がロック許容位置まで回転復帰し、かつコイルバネ100の回転付勢力によりウォームホイル104が上記初期位置に戻るので、出力軸98(及びモータ97)が初期位置まで逆転する。 Arotation support hole 116 formed in a lock release lever 115 which is a thin plate-like rod-shaped member made of metal is fitted in the rotation support shaft 92 of the rear case 81. The lock release lever 115 is supported by the rotation support shaft 92 and can rotate with respect to the rear case 81 on a plane orthogonal to the axis of the rotation support shaft 92. A pressing portion 117 protrudes from the lower end portion of the lock release lever 115. A portion above the rotation support hole 116 forms a substantially linear straddling portion 118 as a whole, and a cam follower 119 projects from an intermediate portion of the straddling portion 118. Further, a pressed protrusion 120 projects upward at the tip end (upper end) of the straddling portion 118.
When thelock release lever 115 is attached to the rear case 81 by fitting the rotation support hole 116 to the rotation support shaft 92, the cam follower 119 is positioned in the front recess 108 of the worm wheel 104 as shown in FIGS. . Further, the straddling portion 118 is located immediately before the worm wheel 104 (opposite the worm wheel 104 in the front-rear direction), straddles the worm wheel 104 upward, and the vicinity of the front end portion of the straddling portion 118 is the front surface of the holding projection (See FIG. 10).
Afront cover 122 whose front shape is substantially the same as that of the rear case 81 is covered on the front surface of the rear case 81. As shown in the drawing, a winding portion of a torsion coil spring 125 located between the lock release lever 115 and the front cover 122 is attached to the rear portion of the rotation support shaft 92. One end of the torsion coil spring 125 is locked to the lock release lever 115, and the other end is locked to a locking protrusion (not shown) formed on the rear surface of the front cover 122. As described above, the lock release lever 115 receives the counterclockwise rotational urging force of FIGS. 6 to 9 from the torsion coil spring 125, so that the cam follower 119 is always applied to the cam surface 110 of the cam portion 109 (with respect to the rotation center shaft 102). In a direction substantially orthogonal). Therefore, when the worm wheel 104 is positioned at the initial position by not pressing the lock release switch S (the motor 97 is in an inoperative state), the lock release lever 115 is positioned at the lock allowable position shown in FIGS. When the worm wheel 104 is rotated to the operating position by pushing the lock release switch (the motor 97 is rotated forward), the cam follower 119 receives the rotational force from the cam surface 110, so that the lock release lever 115 is rotated by the torsion coil spring 125. It rotates to the unlocking position shown in FIG. 9 against the rotational biasing force. When the lock release lever 115 moves to the lock release position, the power supply from the power source to the motor 97 is cut off, so the motor 97 stops. Then, the unlocking lever 115 rotates and returns to the lock allowable position by the biasing force of the torsion coil spring 125, and the worm wheel 104 returns to the initial position by the rotation biasing force of the coil spring 100, so that the output shaft 98 (and the motor 97) Reverse to the initial position.
回転支持孔116を回転支持軸92に嵌合することによりロック解除レバー115を後部ケース81に装着すると、図5~図10に示すようにカムフォロア119はウォームホイル104の前側凹部108内に位置する。さらに跨ぎ部118がウォームホイル104の直前に位置する(ウォームホイル104と前後方向に対向する)とともにウォームホイル104を上方に跨ぎ、跨ぎ部118の後面の先端部近傍が保持用突条95の前面によって摺動可能に支持される(図10参照)。
後部ケース81の前面には、正面形状が後部ケース81と略同一である前部カバー122が被せてある。図示するように回転支持軸92の後部には、ロック解除レバー115と前部カバー122の間に位置する捻りコイルバネ125の巻回部が取り付けてある。捻りコイルバネ125の一端はロック解除レバー115に係止してあり、他端は前部カバー122の後面に形成した係止突起(図示略)に係止してある。このようにロック解除レバー115は捻りコイルバネ125から図6~図9の反時計方向の回転付勢力を受けているため、カムフォロア119はカム部109のカム面110に常に(回転中心軸102に対して略直交する方向に)接触する。従って、ロック解除スイッチSを押さない(モータ97が非作動状態にある)ことによりウォームホイル104が初期位置に位置するとき、ロック解除レバー115は図6~図8に示すロック許容位置に位置し、上記ロック解除スイッチを押す(モータ97が正転する)ことによりウォームホイル104が作動位置まで回転すると、カムフォロア119がカム面110から回転力を受けることにより、ロック解除レバー115は捻りコイルバネ125の回転付勢力に抗して図9に示すロック解除位置まで回転する。ロック解除レバー115がロック解除位置まで移動すると、上記電源からモータ97への給電が遮断されるのでモータ97は停止する。すると、捻りコイルバネ125の付勢力によりロック解除レバー115がロック許容位置まで回転復帰し、かつコイルバネ100の回転付勢力によりウォームホイル104が上記初期位置に戻るので、出力軸98(及びモータ97)が初期位置まで逆転する。 A

以上構成のロックユニット25とアクチュエータユニット80は、アクチュエータユニット80の下端部をロックユニット25の傾斜接続片72の後方部分に位置させた状態で、止めネジ124を傾斜接続片72及び前部カバー122の貫通孔に挿通した上で後部ケース81の雌ネジ孔93に螺合することによって、傾斜接続片72、前部カバー122、及び、後部ケース81を互いに固定している。
ロックユニット25とアクチュエータユニット80を結合することによりロック装置20を構成すると、図6~図9に示すように、ロック解除レバー115の押圧部117がバネ支持部材52の挿通孔62を通って支持ケース26の収納凹部27内に進入し、ポール45の被押圧部49の右側に位置する。 In thelock unit 25 and the actuator unit 80 configured as described above, the set screw 124 is attached to the inclined connection piece 72 and the front cover 122 in a state where the lower end portion of the actuator unit 80 is positioned at the rear portion of the inclined connection piece 72 of the lock unit 25. The inclined connecting piece 72, the front cover 122, and the rear case 81 are fixed to each other by being screwed into the female screw hole 93 of the rear case 81 after being inserted into the through hole.
When thelock device 20 is configured by coupling the lock unit 25 and the actuator unit 80, the pressing portion 117 of the lock release lever 115 is supported through the insertion hole 62 of the spring support member 52, as shown in FIGS. It enters the housing recess 27 of the case 26 and is positioned on the right side of the pressed portion 49 of the pole 45.

次に以上構成のロック装置20の動作について説明する。
図1の仮想線で示すようにバックドア12が開放状態にあるとき、ロック装置20は図6に示すアンロック状態となる。即ち、ストライカ15は支持ケース26のストライカ進入溝29の外部に位置し(図6ではストライカ15の図示略)、フック35は捻りコイルバネ64の付勢力によりアンロック位置に位置し、ポール45は捻りコイルバネ65により係合位置側に回転付勢されているので、アンロック時係合面47がフック35のハーフロック用突部39に係合する。
この状態からバックドア12を閉じ、ストライカ15がストライカ進入溝29(及びストライカ進入溝53、71)に進入すると、ストライカ15によりフック35が捻りコイルバネ64の付勢力に抗して図6の時計方向に回転する。すると図7に示すように、ストライカ15がストライカ進入溝29(及びストライカ進入溝53、71)の内部に進入し、かつフック35が図7に示すハーフロック位置まで回転する。図7に示すように、このときフック35のハーフロック用突部39がポール45の係合突部48に当接するので、仮にこの状態でバックドア12の閉動作を停止すると、フック35はハーフロック位置に保持される。
このハーフロック状態からバックドア12を全閉位置まで閉じると、図8に示すようにストライカ15がストライカ進入溝29(及びストライカ進入溝53、71)のさらに奥側に進入し、かつフック35がロック位置まで回転する。さらに、フック35のロック用突部38がポール45の係合突部48と係合し、フック35の反時計方向の回転を規制するので、ストライカ15がフック35のロック溝37によってロックされる(フック35のストライカ進入溝29、53、71からの脱出が不能となる)。 Next, the operation of thelock device 20 configured as described above will be described.
When theback door 12 is in the open state as shown by the phantom line in FIG. 1, the lock device 20 is in the unlocked state shown in FIG. That is, the striker 15 is positioned outside the striker entry groove 29 of the support case 26 (not shown in FIG. 6), the hook 35 is positioned in the unlocked position by the biasing force of the torsion coil spring 64, and the pole 45 is twisted. Since the coil spring 65 is urged to rotate toward the engagement position, the unlocking engagement surface 47 engages with the half-lock protrusion 39 of the hook 35.
When theback door 12 is closed from this state and the striker 15 enters the striker entry groove 29 (and the striker entry grooves 53 and 71), the hook 35 is twisted by the striker 15 against the urging force of the coil spring 64 in the clockwise direction of FIG. Rotate to. Then, as shown in FIG. 7, the striker 15 enters the striker entry groove 29 (and the striker entry grooves 53 and 71), and the hook 35 rotates to the half-lock position shown in FIG. As shown in FIG. 7, at this time, the half lock projection 39 of the hook 35 comes into contact with the engagement projection 48 of the pole 45. If the closing operation of the back door 12 is stopped in this state, the hook 35 is half Held in the locked position.
When theback door 12 is closed from this half-locked state to the fully closed position, the striker 15 enters further into the striker entry groove 29 (and the striker entry grooves 53 and 71) as shown in FIG. Rotates to the locked position. Further, since the locking projection 38 of the hook 35 engages with the engagement projection 48 of the pole 45 and restricts the counterclockwise rotation of the hook 35, the striker 15 is locked by the lock groove 37 of the hook 35. (The hook 35 cannot escape from the striker entry grooves 29, 53, 71).
図1の仮想線で示すようにバックドア12が開放状態にあるとき、ロック装置20は図6に示すアンロック状態となる。即ち、ストライカ15は支持ケース26のストライカ進入溝29の外部に位置し(図6ではストライカ15の図示略)、フック35は捻りコイルバネ64の付勢力によりアンロック位置に位置し、ポール45は捻りコイルバネ65により係合位置側に回転付勢されているので、アンロック時係合面47がフック35のハーフロック用突部39に係合する。
この状態からバックドア12を閉じ、ストライカ15がストライカ進入溝29(及びストライカ進入溝53、71)に進入すると、ストライカ15によりフック35が捻りコイルバネ64の付勢力に抗して図6の時計方向に回転する。すると図7に示すように、ストライカ15がストライカ進入溝29(及びストライカ進入溝53、71)の内部に進入し、かつフック35が図7に示すハーフロック位置まで回転する。図7に示すように、このときフック35のハーフロック用突部39がポール45の係合突部48に当接するので、仮にこの状態でバックドア12の閉動作を停止すると、フック35はハーフロック位置に保持される。
このハーフロック状態からバックドア12を全閉位置まで閉じると、図8に示すようにストライカ15がストライカ進入溝29(及びストライカ進入溝53、71)のさらに奥側に進入し、かつフック35がロック位置まで回転する。さらに、フック35のロック用突部38がポール45の係合突部48と係合し、フック35の反時計方向の回転を規制するので、ストライカ15がフック35のロック溝37によってロックされる(フック35のストライカ進入溝29、53、71からの脱出が不能となる)。 Next, the operation of the

このようなロック状態を解除するためにはロック解除スイッチSを押す。すると上記電源からモータ97に電流が流れてモータ97が正転するので、モータ97の動力によってウォーム99が正転する。するとウォーム99からウォームホイル104に回転力が伝わり、初期位置に位置していたウォームホイル104が図8の反時計方向に回転し図9に示す作動位置まで回転する。そのため、ウォームホイル104のカム面110によって押圧されたロック解除レバー115が図8のロック許容位置から時計方向に回転して図9に示すロック解除位置に移動する。すると、ロック解除レバー115の押圧部117がポール45の被押圧部49を左側に押圧するので、図9に示すようにポール45が捻りコイルバネ65の付勢力に抗して非係合位置まで回転する。その結果、捻りコイルバネ64の回転付勢力によりフック35がアンロック位置側に回転するので、バックドア12を全開位置側に回転させれば、フック35がアンロック位置まで回転し、ストライカ15がロック溝37(及びストライカ進入溝53、71)から脱出する(ロックが解除される)。
そして、フック35がアンロック位置まで回転したことを図示を省略した検出手段が検出すると、上記電源からモータ97への電流の供給が自動的に遮断されるのでモータ97が回転を停止する。すると、捻りコイルバネ65の回転付勢力によりポール45が図6の係合位置まで時計方向に回転し、捻りコイルバネ125の付勢力によりロック解除レバー115が図6に示すロック許容位置まで回転する。さらに、コイルバネ100の付勢力によりウォームホイル104が初期位置まで回転復帰するので、ウォーム99が初期位置まで逆転する。 In order to release such a locked state, the lock release switch S is pressed. Then, a current flows from the power source to themotor 97 and the motor 97 rotates in the normal direction, so that the worm 99 rotates in the normal direction by the power of the motor 97. Then, the rotational force is transmitted from the worm 99 to the worm wheel 104, and the worm wheel 104 located at the initial position rotates counterclockwise in FIG. 8 to the operation position shown in FIG. Therefore, the lock release lever 115 pressed by the cam surface 110 of the worm wheel 104 rotates clockwise from the lock allowable position in FIG. 8 and moves to the lock release position shown in FIG. Then, the pressing portion 117 of the lock release lever 115 presses the pressed portion 49 of the pole 45 to the left, so that the pole 45 rotates to the disengaged position against the biasing force of the torsion coil spring 65 as shown in FIG. To do. As a result, the hook 35 rotates to the unlocked position side by the rotational biasing force of the torsion coil spring 64. Therefore, if the back door 12 is rotated to the fully open position side, the hook 35 rotates to the unlocked position and the striker 15 is locked. Escape from the groove 37 (and striker entry grooves 53, 71) (the lock is released).
When detection means (not shown) detects that thehook 35 has been rotated to the unlock position, the supply of current from the power source to the motor 97 is automatically cut off, so that the motor 97 stops rotating. Then, the rotation of the torsion coil spring 65 causes the pole 45 to rotate clockwise to the engagement position in FIG. 6, and the urging force of the torsion coil spring 125 rotates the lock release lever 115 to the lock allowable position shown in FIG. Further, since the worm wheel 104 is rotated and returned to the initial position by the urging force of the coil spring 100, the worm 99 is reversed to the initial position.
そして、フック35がアンロック位置まで回転したことを図示を省略した検出手段が検出すると、上記電源からモータ97への電流の供給が自動的に遮断されるのでモータ97が回転を停止する。すると、捻りコイルバネ65の回転付勢力によりポール45が図6の係合位置まで時計方向に回転し、捻りコイルバネ125の付勢力によりロック解除レバー115が図6に示すロック許容位置まで回転する。さらに、コイルバネ100の付勢力によりウォームホイル104が初期位置まで回転復帰するので、ウォーム99が初期位置まで逆転する。 In order to release such a locked state, the lock release switch S is pressed. Then, a current flows from the power source to the
When detection means (not shown) detects that the
なお、モータ97の故障等によりロック解除スイッチSを押してもモータ97が回転しない場合は、バックドア12の底面と背面開口部11の隙間にドライバー等の棒状部材(図示略)を挿入し、該棒状部材をバックドア12の底面に形成した孔(図示略)に通す。すると、該棒状部材の先端部が後部ケース81と前部カバー122の間に形成された隙間A(図4参照)を通って被押圧突起120を押圧するので、ロック解除レバー115がロック解除位置まで回転する。そのため、このような非常事態においてもロック装置20によるロックを解除することが可能である。
If the motor 97 does not rotate even when the lock release switch S is pressed due to a failure of the motor 97 or the like, a rod-like member (not shown) such as a screwdriver is inserted into the gap between the bottom surface of the back door 12 and the back opening 11. The rod-shaped member is passed through a hole (not shown) formed in the bottom surface of the back door 12. Then, the tip of the rod-shaped member presses the pressed protrusion 120 through a gap A (see FIG. 4) formed between the rear case 81 and the front cover 122, so that the lock release lever 115 is unlocked. Rotate until. Therefore, it is possible to unlock the lock device 20 even in such an emergency situation.
以上説明したように本実施形態では、支持ケース26の左右の取付片28に対して重ねる突片を上部カバー70に形成しておらず、しかも係止片73(嵌合部74)を位置決め用凹部31に嵌合することにより上部カバー70(傾斜接続片72を除く部分)の上面を側壁26bの上面と略同一平面上に位置させている(側壁26bの上面の上方に位置させてない)ので、全体の厚みが薄くなっている。そのためバックドア12の厚みを薄くすることが可能である。
また、上部カバー70が取付片28に対して重なる突片を具備していないので、その分だけ上部カバー70を軽量化及び低コスト化できる。
さらに支持ケース26と上部カバー70の位置決め手段(支持ケース26の側壁26bと上部カバー70の位置規制面77を除いた、特許文献1の凸部、位置決め孔、取付片のボルト挿通孔、及び、耳片のねじ孔に相当する位置決め手段)は、支持ケース26の位置決め用凹部31と上部カバー70の係止片73のみなので、支持ケース26と上部カバー70を成形する際は位置決め用凹部31と係止片73の成形位置精度にのみ注意すればよい。そのため支持ケース26と上部カバー70の成形は比較的容易である。
しかも支持ケース26と上部カバー70を組み付けるときには、位置決め用凹部31に係止片73を嵌合させるだけでよいので、支持ケース26と上部カバー70の組付作業を容易に行うことが可能である。 As described above, in this embodiment, theupper cover 70 is not formed with protruding pieces that overlap the left and right mounting pieces 28 of the support case 26, and the locking piece 73 (fitting portion 74) is used for positioning. By fitting into the recess 31, the upper surface of the upper cover 70 (the portion excluding the inclined connection piece 72) is positioned substantially flush with the upper surface of the side wall 26 b (not positioned above the upper surface of the side wall 26 b). So the overall thickness is thin. Therefore, the thickness of the back door 12 can be reduced.
In addition, since theupper cover 70 does not include a protruding piece that overlaps the attachment piece 28, the upper cover 70 can be reduced in weight and cost accordingly.
Further, positioning means for thesupport case 26 and the upper cover 70 (excluding the side wall 26b of the support case 26 and the position restricting surface 77 of the upper cover 70, the convex portion of Patent Document 1, the positioning hole, the bolt insertion hole of the mounting piece, and The positioning means (corresponding to the screw hole of the ear piece) is only the positioning recess 31 of the support case 26 and the locking piece 73 of the upper cover 70, and therefore when positioning the support case 26 and the upper cover 70, the positioning recess 31 It is only necessary to pay attention to the molding position accuracy of the locking piece 73. Therefore, the forming of the support case 26 and the upper cover 70 is relatively easy.
In addition, when thesupport case 26 and the upper cover 70 are assembled, it is only necessary to fit the locking piece 73 into the positioning recess 31, so that the assembly operation of the support case 26 and the upper cover 70 can be easily performed. .
また、上部カバー70が取付片28に対して重なる突片を具備していないので、その分だけ上部カバー70を軽量化及び低コスト化できる。
