Description

車両用リッドロック装置及び蓋開閉機構Lid lock device for vehicle and lid opening / closing mechanism
本発明は、充電ポート用リッドやフューエルリッド等のリッドを開閉するリッド開閉装置及び、開口部を開閉する蓋の開閉機構に関する。 The present invention relates to a lid opening / closing device that opens and closes a lid such as a charging port lid and a fuel lid, and an opening / closing mechanism of a lid that opens and closes an opening.
車両に設けられ、充電ポート用リッドやフューエルリッド等のリッドを開閉するリッドロック装置として、ハートカムを用いてリッドを閉状態からさらに押し込んでリッドを開状態にするリッドロック機構を備えたものがある（特許文献１参照）。 As a lid lock device provided in a vehicle for opening and closing a lid such as a charging port lid and a fuel lid, there is a lid lock mechanism that uses a heart cam to further push the lid from the closed state to open the lid ( See Patent Document 1).
特許文献１に記載のリッドロック装置は、ラッチ部品とハートカムが設けられている部品とが、それぞれの部品の回転軸となる部材で一体に固定され、ラッチ部品とハートカムが設けられている部品とが同軸で回動する。そして、ハートカムが設けられている部品において、ハートカムはラッチ部品の回転軸が直交する面に対して平行な面に設けられている。 In the lid lock device described in Patent Document 1, a latch component and a component provided with a heart cam are integrally fixed by a member serving as a rotation shaft of each component, and a component provided with a latch component and a heart cam. Rotates coaxially. Then, in the component provided with the heart cam, the heart cam is provided on a plane parallel to a plane on which the rotation axes of the latch components are orthogonal.
さらに、特許文献１に記載のリッドロック装置は、集中ロックと連動してハートカムが設けられている部品にロッキングピンを係合させることで、ハートカムが設けられている部品の回動を規制してラッチ部品の回動も規制することができる。ここで、ハートカムが設けられている部品にロッキングピンを係合させる機構は、モータの駆動力と複数の駆動部品とを用いて行うものであり、ラッチ部品の回転軸方向から見てラッチ部品の回転軸から離れた位置に配置されている。 Further, the lid lock device described in Patent Document 1 restricts the rotation of the component provided with the heart cam by engaging the locking pin with the component provided with the heart cam in conjunction with the central lock.

特許文献１に記載のリッドロック装置は、ラッチ部品の回転軸が直交する面とハートカムが設けられている部品のハートカムの面とが平行である。ここで、ラッチ部品及びハートカムが設けられている部品の回転軸となる部材で、ラッチ部品とハートカムが設けられている部品とを連結する場合、回転軸となる部材を固定する部分はハートカムが設けられている部品のハートカム部分を避ける必要がある。そうすると、ハートカムが設けられた部品に回転軸となる部材を固定するスペースが必要となる。また、ラッチ部品をロックに必要な角度で回動させるためにハートカムとして必要な大きさがあるため、ハートカムが設けられている部品にはハートカム自体のスペースも必要となる。したがって、ハートカムが設けられている部品は、ラッチ部品の回転軸方向から見てラッチ部品の回転軸から離れるように位置することとなり、リッドロック装置がより大きくなる原因となる。 In the lid lock device described in Patent Document 1, the surface of the latch component on which the rotation axes are orthogonal to each other and the surface of the heart cam of the component on which the heart cam is provided are parallel to each other. Here, in the case of connecting the latch part and the part provided with the heart cam with the member serving as the rotary shaft of the part provided with the latch part and the heart cam, the part for fixing the member serving as the rotary shaft is provided with the heart cam. It is necessary to avoid the heart cam part of the parts that are installed. Then, a space for fixing the member serving as the rotating shaft to the component provided with the heart cam is required. Further, since there is a size necessary for the heart cam in order to rotate the latch component at an angle required for locking, a space for the heart cam itself is required for the component provided with the heart cam. Therefore, the component provided with the heart cam is located away from the rotation axis of the latch component when viewed from the rotation axis direction of the latch component, which causes the lid lock device to become larger.
また、特許文献１に記載のリッドロック装置は、モータに接続されたウォームギアによって駆動される複数の駆動部品でハートカムが設けられている部品の回動を規制するものであるが、これらの駆動部品はラッチ部品の回転軸から離れた場所に配置されている。そうすると、リッドロック装置において、これらの駆動部品をラッチ部品の回転軸から離れた場所に配置するためのスペースが必要となる。さらに、ハートカムが設けられている部品の回動を規制するための駆動部品が複数あるため部品点数も増加してしまう。したがって、リッドロック装置を小型化することができない。 Further, the lid lock device described in Patent Document 1 restricts the rotation of a component provided with a heart cam among a plurality of drive components driven by a worm gear connected to a motor. Is arranged at a position away from the rotation axis of the latch component. Then, in the lid lock device, a space for arranging these drive components at a position apart from the rotation axis of the latch component is required. Further, since there are a plurality of driving parts for restricting the rotation of the part provided with the heart cam, the number of parts also increases. Therefore, the lid lock device cannot be downsized.

When the lid in the closed state is pushed in the closing direction again by the heart cam 54, the lid 3 is flipped up in the opening direction by the latch 3 so that the lid can be opened. As a result, the operation of opening the lid can be performed without using the operation lever or the operation button in the vehicle interior. Here, the heart cam refers to a groove portion in which a substantially heart-shaped groove is dug, and the tip of a component that engages with the heart cam is guided along the heart cam. Then, depending on the position of the tip of the part that engages with the heart cam in the heart cam, the part provided with the heart cam can be moved or fixed at a specific position. In the present embodiment, a substantially heart-shaped groove dug into the side surface portion 52 of the shaft-shaped member 5 described later serves as the heart cam 54.

（車両用リッドロック装置の動作）
開状態のリッドを閉じてラッチ３をロック位置へ回動させると、ロックピン７の先端部７１がハートカム５４の第１位置５４０ａから第２位置５４０ｂに到達してラッチ３がロック位置で固定されてリッドが閉状態となり、閉状態となったリッドを再度押し込んでラッチ３を押し込み位置へ回動させると、ロックピン７の先端部７１がハートカム５４の第２位置５４０ｂから脱出して第１位置５４０ａに誘導されることでラッチ３がアンロック位置まで回動しリッドが開状態となる。 (Operation of lid lock device for vehicle)
When the opened lid is closed and the latch 3 is rotated to the lock position, the tip portion 71 of the lock pin 7 reaches the second position 540b from the first position 540a of the heart cam 54 and the latch 3 is fixed at the lock position. Then, the lid is closed, and when the closed lid is pushed again to rotate the latch 3 to the pushing position, the tip 71 of the lock pin 7 comes out of the second position 540b of the heart cam 54 and moves to the first position. By being guided by 540a, the latch 3 is rotated to the unlock position and the lid is opened.
さらに、車両用リッドロック装置１の動作について詳しく説明する。図４Ａ及び図５Ａ～図５Ｃに示すように、リッドが開状態でロックピン７の先端部７１がハートカム５４の第１位置５４０ａに位置する場合、トーションバネ６が軸状部材５を右回りのＡ方向に回動させるバネ力を加えることで、第２ストッパ４７にスイッチ押圧部５３の側面が当接し軸状部材５がそれ以上回動できなくなる。これにより、ラッチ３がアンロック位置を維持することができる。一方で軸状部材５の回動が止まることで、ロックピン７の先端部７１はハートカム５４の第１位置５４０ａに留まることとなる。 Further, the operation of the vehicle lid lock device 1 will be described in detail. As shown in FIGS. 4A and 5A to 5C, when the tip 71 of the lock pin 7 is located at the first position 540a of the heart cam 54 with the lid open, the torsion spring 6 rotates the shaft member 5 clockwise. By applying a spring force to rotate in the A direction, the side surface of the switch pressing portion 53 contacts the second stopper 47, and the shaft-shaped member 5 cannot rotate any more. As a result, the latch 3 can maintain the unlocked position. On the other hand, when the rotation of the shaft member 5 is stopped, the tip portion 71 of the lock pin 7 remains at the first position 540a of the heart cam 54.
次にリッドを閉じる動作について説明する。図５Ａ～図５Ｂ及び図６Ａ～図６Ｂに示すように、リッドを押して開状態から閉状態に向かって移動させるとラッチ３に係合したストライカ２１がラッチ３を押し、ラッチ３がトーションバネ６のバネ力に逆らって左回りのＢ方向に回動する。そうすると、ラッチ３に固定されている軸状部材５もトーションバネ６のバネ力に逆らってＢ方向に回動する。これにより、図５Ｃ及び図６Ｃに示すように、ロックピン７の先端部７１が、第１位置５４０ａから第１経路５４５を経由し第１段差５４１を経て第１押し込み位置５４６に到達する。ここで、リッドは開口部２において一旦押し込まれた位置となる。 Next, the operation of closing the lid will be described. As shown in FIGS. 5A to 5B and 6A to 6B, when the lid is pushed and moved from the open state to the closed state, the striker 21 engaged with the latch 3 pushes the latch 3, and the latch 3 pushes the torsion spring 6 It rotates counterclockwise in the B direction against the spring force. Then, the shaft-shaped member 5 fixed to the latch 3 also rotates in the B direction against the spring force of the torsion spring 6. As a result, as shown in FIGS. 5C and 6C, the tip portion 71 of the lock pin 7 reaches the first pushing position 546 from the first position 540a via the first path 545 and the first step 541. Here, the lid is at a position once pushed in the opening 2.
そして、押し込み位置のリッドから手を放すとラッチ３及び軸状部材５は、トーションバネ６のバネ力によりＡ方向に回動する。そうすると、図６Ｂ～図６Ｃに示すように、ハートカム５４がロックピン７の先端部７１を図６Ｃの右方向に誘導することとなる。しかし、ハートカム５４は第１段差５４１によりロックピン７の先端部７１を第１経路５４５方向には誘導できないため、ロックピン７の先端部７１を第２段差５４２を経て第２位置５４０ｂに誘導することとなる。ここで、トーションバネ６が軸状部材５を右回りのＡ方向に回動させるバネ力を加えているので、ハートカム５４はロックピン７の先端部７１を第２位置５４０ｂから左方向に誘導できない。これにより、ラッチ３がロック位置を維持しリッドは閉状態となる。 Then, when the hand is released from the lid at the pushing position, the latch 3 and the shaft-shaped member 5 are rotated in the A direction by the spring force of the torsion spring 6. Then, as shown in FIGS. 6B to 6C, the heart cam 54 guides the tip portion 71 of the lock pin 7 to the right in FIG. 6C. However, since the heart cam 54 cannot guide the tip portion 71 of the lock pin 7 toward the first path 545 by the first step 541, the tip portion 71 of the lock pin 7 is guided to the second position 540b via the second step 542. It will be. Here, since the torsion spring 6 applies a spring force for rotating the shaft-shaped member 5 in the clockwise direction A, the heart cam 54 cannot guide the tip portion 71 of the lock pin 7 leftward from the second position 540b. .. As a result, the latch 3 maintains the locked position and the lid is closed.
最後に、リッドを開く動作について説明する。閉状態となったリッドを再度押し込んでラッチ３を押し込み位置へ回動させると、ラッチ３及び軸状部材５はトーションバネ６のバネ力に逆らってＢ方向に回動する。そうすると、図７Ｂ～図７Ｃに示すように、ハートカム５４がロックピン７の先端部７１を図７Ｃの左方向に誘導することとなる。
しかし、ハートカム５４は第２段差５４２によりロックピン７の先端部７１を第１押し込み位置５４６方向には誘導できないため、ロックピン７の先端部７１を第３段差５４３を経て第２押し込み位置５４７に誘導することとなる。 Finally, the operation of opening the lid will be described. When the closed lid is pushed again and the latch 3 is turned to the pushing position, the latch 3 and the shaft-like member 5 turn in the B direction against the spring force of the torsion spring 6. Then, as shown in FIGS. 7B to 7C, the heart cam 54 guides the tip portion 71 of the lock pin 7 to the left in FIG. 7C.
However, since the heart cam 54 cannot guide the tip 71 of the lock pin 7 toward the first push position 546 by the second step 542, the tip 71 of the lock pin 7 moves to the second push position 547 through the third step 543. You will be guided.
そして、押し込み位置のリッドから手を放すとラッチ３及び軸状部材５は、トーションバネ６のバネ力によりＡ方向に回動する。そうすると、図８Ｂ～図８Ｃに示すように、ハートカム５４はロックピン７の先端部７１をハートカム５４の右方向に誘導することとなる。しかし、ハートカム５４は第３段差５４３によりロックピン７の先端部７１を第２位置５４０ｂ方向には誘導できないため、ロックピン７の先端部７１を第４段差５４４を経て第１位置５４０ａに誘導することとなる。これにより、軸状部材５がトーションバネ６のバネ力でＡ方向に回動すると共に、軸状部材５に固定されているラッチ３が同時にＡ方向に回動してラッチ３に係合しているストライカ２１を押すことでリッド３を外方に押し開きリッドが開状態となる。 Then, when the hand is released from the lid at the pushing position, the latch 3 and the shaft-shaped member 5 are rotated in the A direction by the spring force of the torsion spring 6. Then, as shown in FIGS. 8B to 8C, the heart cam 54 guides the tip portion 71 of the lock pin 7 to the right of the heart cam 54. However, since the heart cam 54 cannot guide the tip 71 of the lock pin 7 toward the second position 540b by the third step 543, the tip 71 of the lock pin 7 is guided to the first position 540a via the fourth step 544. It will be. As a result, the shaft member 5 rotates in the A direction by the spring force of the torsion spring 6, and the latch 3 fixed to the shaft member 5 simultaneously rotates in the A direction and engages with the latch 3. By pushing the striker 21 that is present, the lid 3 is pushed outward and the lid is opened.
（ロックギアの詳細）
本実施の形態の車両用リッドロック装置１は、ロックギア８を備えている。ロックギア８は、ラッチ３の回転軸と同軸に回動可能に配置されるものであって、ロックギア８が非規制位置から規制位置に回動した場合、ロックギア８に設けられた抑止部８４がハートカム５４の一部を覆うことでロックピン７の先端部７１が第２位置５４０ｂから脱出することを妨げることによりリッドが閉状態から開状態へ移動することを規制することができる。 (Details of lock gear)
The vehicle lid lock device 1 according to the present embodiment includes a lock gear 8. The lock gear 8 is rotatably arranged coaxially with the rotation axis of the latch 3, and when the lock gear 8 is rotated from the non-restricted position to the restricted position, the restraining portion provided in the lock gear 8 is provided. The fact that 84 covers a part of the heart cam 54 prevents the tip portion 71 of the lock pin 7 from escaping from the second position 540b, so that the lid can be restricted from moving from the closed state to the open state.
ロックギア８の動作についてさらに詳しく説明する。図９Ａ～図９Ｃに示すように、ロックギア８をモータ９の駆動力によりウォーム９１を介して規制位置まで回動させると、ロックギア８が非規制位置にある場合に比べてロックギア８の抑止部８４及び側壁部８５によってハートカム５４の一部がさらに覆われることとなる。 The operation of the lock gear 8 will be described in more detail. As shown in FIGS. 9A to 9C, when the lock gear 8 is rotated by the driving force of the motor 9 to the regulated position via the worm 91, the lock gear 8 is rotated more than when the lock gear 8 is in the non-regulated position. A part of the heart cam 54 is further covered by the restraining portion 84 and the side wall portion 85.
ここで、ロックギア８が規制位置にある場合におけるロックギア８の抑止部８４及び側壁部８５がハートカム５４の一部を覆う部分について、リッドの状態に応じてそれぞれ説明する。図９Ａに示すようにロックギア８の抑止部８４及び側壁部８５がハートカム５４の一部を覆っている。ここで、ロックギア８の側壁部８５は第１経路５４５を覆っているが、軸状部材５が回動することで側壁部８５は第１経路５４５を覆わなくなり、ハートカム５４がロックピン７の先端部７１を第１経路５４５に沿って誘導する。また、図９Ｂのリッド開状態から閉状態の途中の押し込み位置においては、少なくとも第２位置５４０ｂが抑止部８４または側壁部８５に覆われないようにする必要がある。そして、図９Ｃのリッド閉状態においては、少なくとも第２押し込み位置５４７が抑止部８４で覆われるようにする。 Here, a description will be given of the portions where the restraining portion 84 and the side wall portion 85 of the lock gear 8 that cover a part of the heart cam 54 when the lock gear 8 is in the restricted position, depending on the state of the lid. As shown in FIG. 9A, the restraining portion 84 and the side wall portion 85 of the lock gear 8 cover a part of the heart cam 54. Here, the side wall portion 85 of the lock gear 8 covers the first path 545, but the side wall portion 85 no longer covers the first path 545 as the shaft-shaped member 5 rotates, and the heart cam 54 of the lock pin 7 moves. The tip 71 is guided along the first path 545. 9B, it is necessary to prevent at least the second position 540b from being covered by the restraining portion 84 or the side wall portion 85 at the pushing position in the middle of the lid open state to the closed state. Then, in the lid closed state of FIG. 9C, at least the second pushing position 547 is covered with the restraining portion 84.
そうすると、図９Ｃに示すようにロックピン７の先端部７１が第２位置５４０ｂにある場合、閉状態となったリッドを再度押し込もうとしても、ロックギア８の抑止部８４がハートカム５４の第２押し込み位置５４７を覆っているため、ハートカム５４はロックピン７の先端部７１を第２押し込み位置５４７方向に誘導することができない。これにより、リッドを押し込むことが規制されリッドを開状態にすることができない。 Then, as shown in FIG. 9C, when the tip portion 71 of the lock pin 7 is in the second position 540b, even if the closed lid is pushed in again, the restraining portion 84 of the lock gear 8 causes the lock cam 8 to move to the second position 540b. Since the second push-in position 547 is covered, the heart cam 54 cannot guide the tip portion 71 of the lock pin 7 toward the second push-in position 547. As a result, pushing of the lid is restricted, and the lid cannot be opened.
そして、モータ９の駆動はドアロックの施錠と連動させることもできる。これにより、ドアロックを施錠した場合に、モータ９を駆動してロックギア８の抑止部８４がハートカム５４の一部を覆うようにする。そうすると、ドアロックが施錠されている場合はリッドの閉状態においてリッドを再度押し込んで開状態にできなくなり、ドアロックが開錠されている場合はリッドの閉状態においてリッドを再度押し込んで開状態にすることが可能となる。なお、モータ９の駆動をドアロックの施錠と連動させる以外にリモコンキーに別途設けた操作ボタンで行うようにしてもよい。 The driving of the motor 9 can be linked with the locking of the door lock. As a result, when the door lock is locked, the motor 9 is driven so that the inhibition portion 84 of the lock gear 8 covers a part of the heart cam 54. Then, if the door lock is locked, you cannot push the lid again to open it when the lid is closed.If the door lock is unlocked, push the lid again to open it when the lid is closed. It becomes possible to do. The driving of the motor 9 may be performed by an operation button separately provided on the remote control key, other than interlocking with the locking of the door lock.
さらに、ロックギア８は、解除レバー１２を操作することで規制位置から非規制位置に回動することができる。これにより、モータ９が故障してロックギア８を規制位置から非規制位置にモータ９の駆動力で回動させられなくなったとしても、解除レバー１２を操作してロックギア８を非規制位置に回動することでリッドを押し込んで開状態にすることができる。 Further, the lock gear 8 can be rotated from the restricted position to the non-restricted position by operating the release lever 12. As a result, even if the motor 9 fails and the lock gear 8 cannot be rotated from the restricted position to the non-restricted position by the driving force of the motor 9, the release lever 12 is operated to move the lock gear 8 to the non-restricted position. By rotating the lid, the lid can be pushed into the open state.
なお、本実施の形態においてロックギア８により、ハートカム５４がロックピン７の先端部７１を誘導できないようにしてリッドの押し込みを規制しているが、ロックギア８が直接リッドに係合する等してリッドの押し込みを規制するようにしてもよい。また、軸状部材５またはラッチ３が押し込み位置に回動しないように、ロックギア８が軸状部材５またはラッチ３に直接係合する等してリッドの押し込みを規制してもよい。 In the present embodiment, the lock gear 8 prevents the heart cam 54 from guiding the tip portion 71 of the lock pin 7 to restrict pushing of the lid, but the lock gear 8 is directly engaged with the lid. You may make it regulate the pushing of the lid. Further, the lock gear 8 may be directly engaged with the shaft-shaped member 5 or the latch 3 so as to prevent the shaft-shaped member 5 or the latch 3 from rotating to the push-in position, thereby restricting the pushing-in of the lid.
（実施の形態の作用及び効果）
以上説明した本実施の形態の車両用リッドロック装置１によれば、ラッチ３と同軸で回動する軸状部材５の側面部５２にハートカム５４を設けているため、軸状部材５においてラッチ３を固定する部分とハートカム５４を設ける部分とがラッチ３の回転軸方向から見て重なることがない。さらに軸状部材５においてラッチ３を固定する部分とハートカム５４を設ける部分とを、ラッチ３の回転軸方向から見て近接して配置することができる。また、軸状部材５の側面部５２にハートカム５４やスイッチ押圧部５３を設けているため、軸状部材５を太くする必要はあるものの、ラッチ３の回転軸方向から見てラッチ３の回転軸と直交する平面上にハートカム５４を設ける場合と比べて軸状部材５が大きくなることはない。したがって、車両用リッドロック装置１をより小型化することができる。 (Operation and Effect of Embodiment)
According to the vehicle lid lock device 1 of the present embodiment described above, since the heart cam 54 is provided on the side surface portion 52 of the shaft-shaped member 5 that rotates coaxially with the latch 3, the latch 3 in the shaft-shaped member 5 is provided. The portion for fixing and the portion for providing the heart cam 54 do not overlap with each other when viewed from the rotation axis direction of the latch 3. Further, the portion of the shaft-shaped member 5 where the latch 3 is fixed and the portion where the heart cam 54 is provided can be arranged close to each other when viewed from the rotation axis direction of the latch 3. Further, since the heart cam 54 and the switch pressing portion 53 are provided on the side surface portion 52 of the shaft-shaped member 5, it is necessary to make the shaft-shaped member 5 thick, but the rotation shaft of the latch 3 is viewed from the rotation shaft direction of the latch 3. The shaft-shaped member 5 does not become large as compared with the case where the heart cam 54 is provided on the plane orthogonal to. Therefore, the lid lock device 1 for a vehicle can be further downsized.
そして、本実施の形態の車両用リッドロック装置１によれば、軸状部材５のトーションバネ収容部５７を円形の溝形状として設けることにより、トーションバネ６を軸状部材５の内側に収めることができるようになる。これにより、軸状部材５の回転軸方向にトーションバネ６を収容する空間が不要になるため、車両用リッドロック装置１の回転軸方向の長さを抑制すると共に、太くした軸状部材５の内側のスペースも有効活用できる。 Further, according to the vehicle lid lock device 1 of the present embodiment, the torsion spring 6 is housed inside the shaft-shaped member 5 by providing the torsion spring housing portion 57 of the shaft-shaped member 5 in the shape of a circular groove. Will be able to. As a result, a space for accommodating the torsion spring 6 in the rotation axis direction of the shaft-shaped member 5 becomes unnecessary, so that the length of the vehicle lid lock device 1 in the rotation axis direction can be suppressed and the thickened shaft-shaped member 5 can be prevented. The inner space can also be used effectively.
また、本実施の形態の車両用リッドロック装置１によれば、ハートカム５４を設けた軸状部材５の回転軸と同軸で回動するロックギア８により軸状部材５の回動を規制することができる。そうすると、ロックギア８をロックギア８の回転軸と軸状部材５及びラッチ３の回転軸とが同軸になるように配置することができるため、ラッチ３の回転軸方向から見てロックギア８を配置するためのスペースを最小限にすることができる。さらに、ロックギア８はモータ９に接続されたウォーム９１によって直接駆動される１つの部品である。したがって、車両用リッドロック装置１をより少ない部品で構成できると共に、より小型化することができる。 Further, according to the vehicle lid lock device 1 of the present embodiment, the rotation of the shaft-shaped member 5 is restricted by the lock gear 8 that rotates coaxially with the rotation shaft of the shaft-shaped member 5 provided with the heart cam 54. You can Then, the lock gear 8 can be arranged so that the rotation shaft of the lock gear 8 and the rotation shafts of the shaft-shaped member 5 and the latch 3 are coaxial with each other. The space for placement can be minimized. Further, the lock gear 8 is one component that is directly driven by the worm 91 connected to the motor 9. Therefore, the lid lock device 1 for a vehicle can be configured with fewer parts and can be further downsized.
さらに本実施の形態の車両用リッドロック装置１によれば、車両のドアロックの施錠とリッドロックの施錠とが連動できるため、ドアロックが施錠されている場合に第三者がリッドを開くことができない。これにより、第三者が車両の充電ポートの内部にアクセスして車両を破損させたり、バッテリ―に充電されている電力を充電ポートから盗んだりすることを防ぐことが可能となる。 Further, according to the vehicle lid lock device 1 of the present embodiment, locking of the vehicle door lock and locking of the lid lock of the vehicle can be linked, so that a third person can open the lid when the door lock is locked. I can't. This makes it possible to prevent a third party from accessing the inside of the charging port of the vehicle and damaging the vehicle, or stealing the electric power charged in the battery from the charging port.
加えて本実施の形態の車両用リッドロック装置１によれば、ロックギア８は規制位置において、リッドが開状態から閉状態へ移動することを許容することができる。具体的には図９Ａ～図９Ｃに示すように、リッドが開状態でモータ９を駆動してロックギア８を規制位置に回動したとしても、ハートカム５４がロックピン７の先端部７１を誘導できるのでリッドを開状態から閉状態にすることが可能である。これにより、リッドを閉じる前にドアロックを施錠した場合でもリッドを閉状態にすることができると共に、閉状態から再度リッド押し込んで開状態にすることを防ぐことが可能となる。 In addition, according to the vehicle lid lock device 1 of the present embodiment, the lock gear 8 can allow the lid to move from the open state to the closed state in the regulation position. Specifically, as shown in FIGS. 9A to 9C, even when the motor 9 is driven and the lock gear 8 is rotated to the regulation position with the lid open, the heart cam 54 guides the tip portion 71 of the lock pin 7. As a result, the lid can be changed from the open state to the closed state. This makes it possible to close the lid even when the door lock is locked before closing the lid, and to prevent the lid from being pushed again from the closed state to the open state.
