Description

进退移动装置 技术领域
本发明涉及进退移动装置。
背景技术
将覆盖车辆的燃料补给口的盖锁定的装置等杆构件相对于壳体移动的装置构成为，在杆构件以从壳体突出的方式前进的位置和以收容于壳体的方式后退的位置之间往复移动(例如，参照专利文献1)。
专利文献1的装置具备：壳体、在相对于壳体前进的位置与后退的位置之间移动的推杆(杆构件)、对推杆向突出方向施力的施力构件、在推杆被保持在后退的位置时锁定推杆的上锁部(锁定构件)。
在专利文献1中，推杆在盖打开时向前进方向移动后，被保持在规定的前进保持位置。另外，推杆在盖闭锁时向后退方向移动后，被保持在规定的后退保持位置。以下，对推杆从处于前进保持位置的状态到被保持在后退保持位置的过程进一步进行详细说明。当位于前进保持位置的推杆在盖闭锁时被向后退方向按压时，推杆在到达后退保持位置后，越过后退保持位置而进一步向后退方向移动。然后，推杆通过施力构件的作用力而向前进方向返回后，被保持在后退保持位置。另外，推杆在被保持在前进保持位置之前的过程中，从后退保持位置向后退方向移动后，通过施力构件的作用力向前进方向移动而被保持在前进保持位置。
另外，专利文献1的装置具有用于在后退保持位置锁定推杆的上锁部(锁定构件)。上锁部具有与推杆的销状的滑动件卡合的卡合构件，通过卡合构件在与推杆的轴垂直的方向上移动，与销状的滑动件卡合。具体而言，在推杆位于后退保持位置时，上锁部的卡定构件朝向设置 于推杆的外周的销状的滑动件移动。由此，卡合构件在推杆的前进/后退方向上与销状的滑动件卡合，锁定推杆。另一方面，在推杆位于前进保持位置时，即使上锁部的卡定构件朝向推杆移动，卡合构件也与销状的滑动件的端面抵接而阻止卡合构件的移动。由此，在推杆位于前进保持位置时，卡合构件不移动到锁定位置，防止推杆的误锁定。

发明内容
发明所要解决的课题
在专利文献1这样的装置的情况下，例如，在盖打开的状态等进退构件位于前进保持位置时，即使进行使锁定构件移动到锁定位置的操作，锁定构件也不会移动到锁定位置。因此，需要在使进退构件从前进保持位置移动到后退保持位置后，再次进行使锁定构件移动到锁定位置的操作。因此，进退构件的锁定操作繁琐。另外，在进退构件移动到后退保持位置的状态下用户忘记了锁定操作的情况下，进退构件成为不锁定的状态(例如，成为盖能够打开的状态)。

具体实施方式
以下，参照附图，对本发明的一个实施方式的进退移动装置进行说明。此外，以下所示的实施方式只不过是一例，本发明的进退移动装置不限于以下的实施方式。此外，在本说明书中，“与A垂直”及与其类似的表现不仅指相对于A完全垂直的方向，还包括相对于A大致垂直的方向。另外，在本说明书中，“与B平行”及与其类似的表现不仅指相对于B完全平行的方向，还包括相对于B大致平行的方向。另外，在本说明书中，“C形状”及与其类似的表现不仅指完全的C形状，还包括在外观上联想C形状的形状(大致C形状)。
如图1所示，进退移动装置1具备：壳体2；及进退构件3，能够相对于壳体2在从壳体2突出的前进方向D1以及作为与前进方向D1相反的方向的后退方向D2上一边绕轴X旋转一边移动。此外，将前进方向D1及后退方向D2这个两个方向统称为轴X方向。在本说明书中，轴X是指进退构件3沿着前进及后退(进退)的方向的轴即进退轴。在本实施方式中，轴X与成为在进退方向上细长的轴状的构件的进退构件3的长度方向轴相对应。
进退移动装置1在进退构件3相对于壳体2进退时，与规定的操作对象相互作用。此外，进退构件3与操作对象之间的相互作用既可以是进退构件3作用于操作对象，也可以是操作对象作用于进退构件3。在本实施方式中，通过操作作为操作对象的盖L(参照图2及图3)，进退构件3被操作。但是，进退构件3与操作对象之间的相互作用没有特别限定，也可以是通过进退构件3按压操作对象来操作操作对象等其他的作用。
进退移动装置1的用途只要在进退构件3相对于壳体2进退时能够与规定的操作对象相互作用，就没有特别限定。在本实施方式中，如图3所示，进退移动装置1适用于具备进退移动装置1、安装有进退 移动装置1且具有开口部Ba的基部B、能够开闭基部B的开口部Ba且能够与进退构件3的前进方向D1侧的端部(卡定部31)卡合的盖L的盖开闭装置D。更具体而言，盖L是车辆的燃料或供电用的盖，进退移动装置1适用于车辆的盖开闭装置D，构成为对作为操作对象的车辆的燃料或供电用的盖L进行开闭。此外，车辆的燃料不限于轻油、汽油，是指能够使车辆动作的所有的燃料。
在本实施方式中，如图3所示，盖开闭装置D具备：经由铰链H可开闭地设置于作为基部的车身(以下，称为车身B)的盖(以下，有时称为燃料盖)L、安装于车身B且通过进退构件3的进退对燃料盖L进行卡定及卡定解除的进退移动装置1。燃料盖L具有供设置于进退构件3的前端的卡定部31卡定的操作对象侧被卡定部La。在本实施方式中，卡定部31为矩形板状的卡定片，操作对象侧被卡定部La是具有能够卡定卡定部31的矩形状的开口的卡定孔。如图2的单点划线所示，在成为卡定部31能够从操作对象侧被卡定部La的开口脱离的配置时，能够解除卡定部31与操作对象侧被卡定部La之间的卡定。另一方面，在卡定部31从图2的单点划线的状态旋转到由实线所示的状态，成为不能从操作对象侧被卡定部La的开口脱离的配置时，卡定部31与操作对象侧被卡定部La卡定。
虽详细内容后述，但在本实施方式中，通过从燃料盖L闭锁的状态按压燃料盖L而操作进退移动装置1，从而解除卡定部31与操作对象侧被卡定部La之间的卡定，打开燃料盖L。燃料盖L也可以在卡定部31与操作对象侧卡定部La之间的卡定被解除时，向燃料盖L打开的方向被弹簧施力而打开。或者，燃料盖L也可以在被进退构件3向打开方向按压而稍微打开后，利用手动打开。在从图3所示的燃料盖L打开的状态将燃料盖L闭锁的情况下，手动使燃料盖L向闭锁方向移动。由此，进退构件3被燃料盖L按压，从而进退构件3后退。此时，卡定部31从由图2的单点划线所示的状态旋转到由实线所示的状态，卡定在操作对象侧被卡定部La而维持燃料盖L闭锁的状态。
接着，对进退移动装置1的详情进行说明。
如图4～图9所示，进退移动装置1具备：施力构件4，对进退构件3向前进方向D1施力；凸轮机构C，构成为将进退构件3保持在向前进方向D1移动后的前进保持位置(参照图4及图7)和向后退方向D2移动后的后退保持位置(参照图5及图8)；锁定构件5，在进退构件3位于后退保持位置时，能够在限制进退构件3向前进保持位置的移动的锁定位置(参照图7～图9)、和允许进退构件3向前进保持位置的移动的解锁位置(参照图4～图6)之间移动。此外，在图4～图9中，为了容易观察壳体2的内部，将壳体2部分地拆下而进行图示。
壳体2在内部收容进退移动装置1的结构构件。在本实施方式中，如图4及图10所示，壳体2收容进退构件3的一部分、施力构件4、凸轮机构C、锁定构件5。此外，壳体2只要收容进退移动装置1的各结构构件的至少一部分即可，未必需要收容各结构构件的整体。壳体2只要能够在内部收容进退移动装置1的结构构件，其形状、构造就没有特别限定。另外，壳体2可以由一个构件构成，也可以由多个部件构成。
在本实施方式中，如图4及图10所示，壳体2具有收容进退构件3的进退构件收容部21和收容锁定构件5的锁定构件收容部22。进退构件收容部21具有可在轴X方向上进退地收容进退构件3的收容空间。在本实施方式中，如图4所示，进退构件收容部21由具有内部空间的筒状体构成。更具体而言，进退构件收容部21由具有后述的第二凸轮面Cb及引导部Cc的圆筒体构成。锁定构件收容部22以锁定构件5能够在锁定位置与解锁位置之间移动的方式收容锁定构件5。在本实施方式中，锁定构件收容部22收容锁定构件5的锁定主体51、驱动部52的电动机521及螺纹轴522。
另外，在本实施方式中，如图4所示，壳体2具有突出部23，突出部23从在轴X方向上与进退构件3的后退方向D2侧的端部相对的底面2a突出，具有后述的第一凸轮面Ca。突出部23设置于在轴X方向上与进退构件收容部21相对的位置。突出部23在绕轴X方向上分离地设置有多个(在本实施方式中为4个)。另外，在本实施方式中，壳体2具有从底面2a向前进方向D1突出且支承施力构件4的支承轴24。支承轴24与进退构件3的轴X在同轴上延伸。
进退构件3是相对于壳体2在轴X方向上进退的构件。在本实施方式中，进退构件3通过凸轮机构C向前进方向D1移动而被保持在前进保持位置(参照图4及图7)，并相对于前进保持位置向后退方向D2移动而被保持在后退保持位置(参照图5及图8)。如图4～图6、图13～图16所示，进退构件3构成为，在前进保持位置与后退保持位置之间移动时，通过相对于后退保持位置进一步靠后退方向D2侧的折回位置(参照图6、图14的双点划线及图16的双点划线)。进退构件3在轴X方向上进退时，一边通过凸轮机构C绕轴X旋转一边移动。具体而言，进退构件3构成为，在后退保持位置与折回位置之间移动时，通过凸轮机构C绕轴X旋转。
在本说明书中，“前进保持位置”是进退构件3相对于后退保持位置向前进方向D1移动而被保持的进退构件3的规定的位置(参照图4及图7)。在本实施方式中，前进保持位置是燃料盖L打开的状态时的进退构件3的位置，是进退构件3从壳体2向前进方向D1最突出的位置。“后退保持位置”是进退构件3相对于前进保持位置向后退方向D2移动而被保持的进退构件3的规定的位置(参照图5及图8)。在本实施方式中，后退保持位置是燃料盖L为闭锁状态时的进退构件3的位置。在本实施方式中，后退保持位置是相对于折回位置稍微靠前进方向D1侧的位置。此外，在本实施方式中，进退构件3的后退保持位置成为相对于前进保持位置在绕轴X的方向上错开90°的位置。“折 回位置”是相对于后退保持位置进一步靠后退方向D2侧的位置(参照图6)。在本实施方式中，折回位置是在通过凸轮机构C使进退构件3从前进保持位置向后退保持位置移动时或者使进退构件3从后退保持位置向前进保持位置移动时，进退构件3从后退方向D2向前进方向D1切换行进方向的轴X方向的位置。此外，在进退构件3从前进保持位置向后退保持位置移动时切换行进方向的折回位置(第一折回位置。参照图14的双点划线)的轴X方向的位置与在进退构件3从后退保持位置向前进保持位置移动时切换行进方向的折回位置(第二折回位置。参照图16的双点划线)的轴X方向的位置可以不同。
进退构件3如上所述在轴X方向上进退时，与规定的操作对象相互作用。在本实施方式中，在进退构件3移动到前进保持位置时解除与燃料盖L的卡合状态，使燃料盖L为打开状态，在移动到后退保持位置时，与燃料盖L卡合，使燃料盖L为闭锁状态。在本实施方式中，如图4所示，进退构件3构成为，被螺旋弹簧等施力构件4向前进方向D1施力，从而从后退保持位置向前进保持位置移动。相反，进退构件3通过抵抗施力构件4的向前进方向D1的作用力而被按压，从而从前进保持位置向后退保持位置移动。
在本实施方式中，如图11所示，进退构件3具备沿轴X方向延伸的主体32、在轴X方向上设置于主体32的一端(前端)侧的卡定部31。另外，进退构件3在进退构件3(主体32)的另一端侧(后退方向D2侧的端部侧)具有后述的凸部3a及凹部3b。另外，进退构件3在进退构件3的绕轴X的外周侧面具有被引导部Cd。
在本实施方式中，如图11所示，主体32是在轴X方向上延伸的筒状或柱状的构件。更具体而言，主体32形成为圆筒状，如图4～图9所示，被筒状的进退构件收容部21引导。另外，如图11及图12所示，主体32在主体32的内部具有施力构件收容部321，施力构件4的一部分被收容于施力构件收容部321。
卡定部31设置于主体32的一端侧(前进方向D1侧)，与燃料盖L等操作对象卡定。在本实施方式中，如图2所示，卡定部31与操作对象侧被卡定部La卡定。通过利用凸轮机构C使进退构件3绕轴X方向旋转，卡定部31在与操作对象侧被卡定部La卡定的卡定状态(参照图2的实线)与解除了卡定的卡定解除状态(参照图2的单点划线)之间移动。在本实施方式中，卡定部31是在壳体2的外侧设置于主体32的前进方向D1侧的端部的大致矩形的板状构件。此外，卡定部31及操作对象侧被卡定部La的形状、构造只要能够使卡定部31相对于操作对象侧被卡定部La形成卡定状态及卡定解除状态，能够开闭燃料盖L，就没有特别限定。
凸轮机构C使进退构件3在前进保持位置、折回位置及后退保持位置之间移动，将进退构件3保持在前进保持位置和后退保持位置。凸轮机构C在使进退构件3在前进保持位置与后退保持位置之间移动时，以使进退构件3通过相对于后退保持位置进一步靠后退方向D2侧的折回位置的方式引导进退构件3。更具体而言，如图13～图15所示，凸轮机构C构成为，在使进退构件3从前进保持位置向后退保持位置移动时，在进退构件3到达折回位置后，利用施力构件4使进退构件3从折回位置移动到后退保持位置而进行保持。另外，如图15及图16所示，凸轮机构C构成为，在使进退构件3从后退保持位置向前进保持位置移动时，在进退构件3从后退保持位置到达折回位置后，利用施力构件4使进退构件3从折回位置移动到前进保持位置而进行保持。此外，图13～图19是为了容易理解而将进退构件3及凸轮机构C在平面上展开的概略图，图13～图19中的上下方向为轴X方向(上方向为前进方向D1，下方向为后退方向D2)，左方向为绕轴X方向的一个方向D3。
凸轮机构C在进退构件3从前进保持位置向后退保持位置移动时及进退构件3从后退保持位置向前进保持位置移动时，使进退构件3 绕轴X旋转。更具体而言，进退构件3在从前进保持位置向后退保持位置移动时，通过凸轮机构C绕轴X向一个方向D3(图4参照)旋转，在从后退保持位置向前进保持位置移动时，也通过凸轮机构C绕轴X向一个方向D3(相同方向)旋转。从进退构件3保持在前进保持位置的状态到保持在后退保持位置的状态为止，或者从进退构件3保持在后退保持位置的状态到保持在前进保持位置的状态为止，进退构件3旋转的角度没有特别限定。在本实施方式中，从进退构件3保持在后退保持位置的状态到保持在前进保持位置的状态为止，进退构件3构成为旋转约90°。同样地，从进退构件3保持在前进保持位置的状态到保持在后退保持位置的状态为止，进退构件3构成为旋转约90°。
凸轮机构C的构造只要能够使进退构件3在前进保持位置、折回位置及后退保持位置之间移动，并使进退构件3保持在前进保持位置和后退保持位置，就没有特别限定。在本实施方式中，如图13～图16所示，凸轮机构C具有设置于壳体2的第一凸轮面Ca、设置于壳体2的第二凸轮面Cb、设置于壳体2且沿进退构件3的轴X方向延伸的引导部Cc、设置于进退构件3的外周，具有与第一凸轮面Ca接触的第一接触面Cd1及与第二凸轮面Cb接触的第二接触面Cd2且能够被引导部Cc引导的被引导部Cd。此外，在本说明书中，在某个构件/部位被称为“设置于壳体2”的情况下，意味着某个构件/部位可以与壳体2的其他部位一体地设置，也可以与壳体2的其他部位分体设置。在某个构件/部位与壳体2的其他部位分体设置的情况下，只要能够达到发明的目的，就可以固定于壳体2的其他部位，也可以是相对于壳体2的其他部位能够相对移动。
如图14及图16所示，第一凸轮面Ca以如下方式倾斜：在进退构件3向后退方向D2移动而向折回位置移动时，与被引导部Cd的第一接触面Cd1接触，而使进退构件3在绕轴X方向上向一个方向D3旋转。第一凸轮面Ca以如下方式倾斜：在与第一接触面Cd1接触的状态下，当进退构件3欲向后退方向D2(被按压)进一步移动时，产生使 进退构件3绕轴X向一个方向D3旋转的力。第一凸轮面Ca的倾斜角只要是在第一凸轮面Ca与第一接触面Cd1接触的状态下，进退构件3欲向后退方向D2(被按压)进一步移动时，产生使进退构件3绕轴X向一个方向D3旋转的力的倾斜角，就没有特别限定。
在本实施方式中，第一凸轮面Ca设置于壳体2。更具体而言，如图4所示，第一凸轮面Ca由从壳体2的底面2a突出的突出部23的前进方向D1侧的端部(上端)构成。在本实施方式中，在绕轴X的方向上以等间隔分离地在壳体2的底面2a设置有4个突出部23，在4个突出部23的每一个设置有第一凸轮面Ca。另外，在本实施方式中，如图13所示，第一凸轮面Ca中的一个设置在与进退构件3被保持在前进保持位置时的被引导部Cd的绕轴X方向上的位置对应的位置。另外，在本实施方式中，如图15所示，第一凸轮面Ca中的另一个设置在与进退构件3被保持在后退保持位置时的被引导部Cd的绕轴X方向上的位置对应的位置。因此，在进退构件3从前进保持位置或后退保持位置向后退方向D2移动时，能够使第一凸轮面Ca与被引导部Cd的第一接触面Cd1可靠地接触。
如图14及图15所示，第二凸轮面Cb以如下方式倾斜：在进退构件3从前进保持位置经由折回位置被保持在后退保持位置时，在进退构件3从折回位置向前进方向D1移动时，与被引导部Cd的第二接触面Cd2接触，而使进退构件3在绕轴X方向上向一个方向D3旋转。如图15所示，第二凸轮面Cb以下方式倾斜：在与第二接触面Cd2接触的状态下，当进退构件3(通过施力构件4的作用力)欲向前进方向D1进一步移动时，产生使进退构件3在绕轴X方向上向一个方向D3旋转的力。第二凸轮面Cb的倾斜角只要是在第二凸轮面Cb与第二接触面Cd2接触的状态下，在进退构件3欲向前进方向D1进一步移动时，产生使进退构件3在绕轴X方向上向一个方向D3旋转的力的倾斜角，就没有特别限定。
在本实施方式中，第二凸轮面Cb设置于壳体2。更具体而言，如图4～图9所示，第二凸轮面Cb设置于壳体2的进退构件收容部21。在本实施方式中，第二凸轮面Cb由设置在由筒状体构成的进退构件收容部21的倾斜面(后退方向D2侧的端部的倾斜面)构成。在本实施方式中，如图13所示，在进退构件收容部21的后退方向D2侧的端部，在绕轴X的方向上分离地设置有2个第二凸轮面Cb。在本实施方式中，如图13所示，1个第二凸轮面Cb从1个第一凸轮面Ca(突出部23)的在绕轴X的方向上的一个方向D3侧的端部(图13的左侧的端部)延伸至相邻的另1个第一凸轮面Ca(突出部23)的绕轴X的方向上的一个方向D3侧的端部。第二凸轮面Cb在绕轴X的方向上的一个方向D3侧的端部(在图13中，第二凸轮面Cb的左侧的端部)具有使沿着第二凸轮面Cb向一个方向D3移动的被引导部Cd停止在规定的位置(后退保持位置)的停止部ST(参照图13)。停止部ST由相对于第二凸轮面Cb的倾斜面向后退方向D2延伸的壁部构成。另外，第二凸轮面Cb在绕轴X的方向上的另一个方向侧的端部(在图13中，第二凸轮面Cb的右侧的端部)，与引导部Cc的后退方向D2侧的开放的端部相连。
引导部Cc在轴X方向上引导进退构件3的被引导部Cd。引导部Cc在轴X方向上延伸，在进退构件3从前进保持位置朝向后退方向D2移动时，或者在进退构件3朝向前进保持位置向前进方向D1移动时，在轴X方向上引导被引导部Cd，辅助进退构件3在轴X方向上顺畅地移动。
在本实施方式中，引导部Cc设置于壳体2。更具体而言，引导部Cc设置于壳体2的进退构件收容部21。在本实施方式中，如图4～图9所示，引导部Cc由引导槽构成，该引导槽在由筒状体构成的进退构件收容部21的侧面在轴X方向上以规定的宽度切缺而成。引导部Cc为了能够在引导部Cc内引导被引导部Cd，沿轴X方向延伸的一对侧缘的间隔即引导部Cc的宽度(绕轴X的方向的宽度)大于绕轴X的 方向上的被引导部Cd的宽度。引导部Cc的前进方向D1侧的端部具有能够与被引导部Cd抵接的停止部ST2(参照图13)，通过停止部ST2与被引导部Cd的第二接触面Cd2接触，进退构件3在前进保持位置停止而被保持。引导部Cc的后退方向D2侧的端部开放，被引导部Cd能够从引导部Cc的内侧朝向第一凸轮面Ca向后退方向D2移动，从引导部Cc的后退方向D2侧朝向引导部Cc的内侧向前进方向D1移动。
另外，凸轮机构C具有导入部Ce，导入部Ce在进退构件3从后退保持位置经由折回位置朝向前进保持位置时(参照图15及图16)，将被引导部Cd向引导部Cc引导。导入部Ce以如下方式倾斜：在与被引导部Cd的第二接触面Cd2接触的状态下，当进退构件3(通过施力构件4的作用力)欲向前进方向D1进一步移动时，产生进退构件3在绕轴X的方向上向一个方向D3旋转的力。导入部Ce的倾斜角只要是在导入部Ce与第二接触面Cd2接触的状态下，在进退构件3欲向前进方向D1进一步移动时，产生进退构件3在绕轴X的方向上向一个方向D3旋转的力的倾斜角，就没有特别限定。
在本实施方式中，导入部Ce设置于壳体2。更具体而言，导入部Ce设置于壳体2的进退构件收容部21。在本实施方式中，如图4所示，导入部Ce由设置于由筒状体构成的进退构件收容部21的倾斜面(后退方向D2侧的端部的倾斜面)构成。在本实施方式中，如图13所示，在进退构件收容部21的后退方向D2侧的端部，在绕轴X的方向上分离地设置有2个导入部Ce。在本实施方式中，导入部Ce在绕轴X的方向上隔着停止部ST与第二凸轮面Cb相邻地设置。另外，导入部Ce在绕轴X的方向上设置在引导部Cc与第二凸轮面Cb之间。
被引导部Cd设置于进退构件3。如图13～图16所示，被引导部Cd被第一凸轮面Ca、第二凸轮面Cb、引导部Cc等引导，由此，进退构件3向前进保持位置、后退保持位置、折回位置移动。在本实施方 式中，如图11及图12所示，被引导部Cd设置于进退构件3的外周。更具体而言，被引导部Cd从在进退构件3的主体32的绕轴X的方向上延伸的侧面突出设置。被引导部Cd具有与第一凸轮面Ca接触的第一接触面Cd1及与第二凸轮面Cb接触的第二接触面Cd2。另外，被引导部Cd与引导部Cc的一对侧缘相对，具有在轴X方向上延伸的一对相对侧缘。在进退构件3的被引导部Cd被引导部Cc引导时，一对相对侧缘能够相对于引导部Cc的一对侧缘滑动。
被引导部Cd的形状只要能够是被引导部Cd被第一凸轮面Ca、第二凸轮面Cb、引导部Cc等引导而进退构件3能够向前进保持位置、后退保持位置、折回位置移动，就没有特别限定。在本实施方式中，如图13所示，被引导部Cd形成为绕轴X的方向的一方为上底、另一方为下底的等腰梯形形状。
第一接触面Cd1是在进退构件3向后退方向D2移动时与第一凸轮面Ca接触的面。如图14所示，在第一接触面Cd1与第一凸轮面Ca接触的状态下，进退构件3进一步向后退方向D2移动，由此进退构件3在绕轴X的方向上向一个方向D3旋转。第一接触面Cd1的形状及构造只要在与第一凸轮面Ca接触的状态下，通过进退构件3进一步向后退方向D2移动，能够使进退构件3在绕轴X的方向上向一个方向D3旋转，就没有特别限定。在本实施方式中，第一接触面Cd1以与第一凸轮面Ca的倾斜角对应的角度向相同方向倾斜。
在进退构件3从前进保持位置向后退保持位置移动时从折回位置向前进方向D1移动时，第二接触面Cd2与第二凸轮面Cb接触。另外，在本实施方式中，当进退构件3从后退保持位置向前进保持位置移动时从折回位置向前进方向D1移动时，第二接触面Cd2与导入部Ce接触。如图15及图16所示，在第二接触面Cd2与第二凸轮面Cb或导入部Ce接触的状态下，通过进退构件3进一步向前进方向D1移动，从而进退构件3在绕轴X的方向上向一个方向D3旋转。第二接触面Cd2 的形状及构造只要是在与第二凸轮面Cb或导入部Ce接触的状态下，通过进退构件3进一步向前进方向D1移动，能够使进退构件3在绕轴X的方向上向一个方向D3旋转，就没有特别限定。在本实施方式中，第二接触面Cd2以与第二凸轮面Cb及导入部Ce的倾斜角对应的角度向相同方向倾斜。
锁定构件5在位于锁定位置时，限制进退构件3从后退保持位置向前进保持位置移动(参照图9及图19)。更具体而言，锁定构件5通过限制进退构件3从后退保持位置朝向折回位置向后退方向D2移动，限制进退构件3从后退保持位置向前进保持位置移动。
如上所述，锁定构件5在锁定位置(参照图10的实线的位置)与解锁位置(参照图10的双点划线的位置)之间移动。锁定构件5的锁定位置是在进退构件3位于后退保持位置时能够限制进退构件3向前进保持位置的移动的位置。更具体而言，锁定位置是在进退构件3欲从后退保持位置朝向折回位置向后退方向D2移动时能够阻挡进退构件3向后退方向D2的移动以使进退构件3无法从后退保持位置到达折回位置的位置(参照图19)。如图4及图17～图19所示，锁定构件5具有设置于锁定构件5的前进方向D1侧的被抵接部5a。被抵接部5a与后述的进退构件3的抵接部CT抵接，限制进退构件3向后退方向D2的移动。此外，在本实施方式中，处于锁定位置的锁定构件5限制进退构件3向后退方向D2的移动，但进退构件3的前进方向D1的移动及绕轴X的方向的旋转不受限制。另外，解锁位置是锁定构件5从前进保持位置与后退保持位置之间的进退构件3的移动轨迹上脱离而允许进退构件3向前进保持位置的移动的位置。
在本实施方式中，如图10所示，锁定构件5从与轴X垂直的方向向接近轴X的方向移动，从解锁位置(参照图10的双点划线)向锁定位置(参照图10的实线)移动。但是，锁定构件5的移动方向只要设置为能够在锁定位置与解锁位置之间移动，就没有特别限定。例如， 锁定构件5也可以从解锁位置向锁定位置在轴X方向上移动(例如锁定构件5也可以从解锁位置向前进方向D1(在图4中从下向上)移动而到达锁定位置)。
锁定构件5的形状及构造只要能够在锁定位置与解锁位置之间移动，就没有特别限定。在本实施方式中，如图4～图10所示，锁定构件5具有能够与进退构件3抵接的锁定主体51、使锁定主体51移动到锁定位置及解锁位置的驱动部52。
锁定主体51在位于锁定位置时，通过与进退构件3的抵接部CT抵接，将进退构件3向后退方向D2的移动限制在规定范围，限制进退构件3到达折回位置。如图4～图9所示，锁定主体51具有在位于锁定位置时与进退构件3的抵接部CT在轴X方向上相对的被抵接部5a。
锁定主体51的形状及构造只要能够通过与进退构件3的抵接部CT抵接，将进退构件3向后退方向D2的移动限制在规定范围，限制进退构件3到达折回位置，就没有特别限定。在本实施方式中，如图4～图10所示，锁定主体51具有被驱动部52驱动的被驱动部511、从被驱动部511延伸且具有被抵接部5a的延伸设置部512。在本实施方式中，被驱动部511具有与驱动部52的螺纹轴522的外周螺合的内螺纹部。被驱动部511在螺纹轴522绕轴旋转时，被限制与螺纹轴522一起旋转。由此，当螺纹轴522绕轴旋转时，根据螺纹轴522的旋转方向，包含被驱动部511的锁定主体51沿螺纹轴522的轴向移动。由此，锁定主体51能够向锁定位置、解锁位置移动。延伸设置部512的形状没有特别限定，但在本实施方式中，以L字状延伸。被抵接部5a作为平坦面设置于延伸设置部512的前端的前进方向D1侧。此外，如图7～图9所示，延伸设置部512构成为，在锁定构件5位于锁定位置时，进入在绕轴X的方向上相邻的一对突出部23之间的空间。
驱动部52使锁定主体51移动到锁定位置及解锁位置。驱动部52 的构造只要能够使锁定主体51移动到锁定位置及解锁位置，就没有特别限定。在本实施方式中，驱动部52是电动的驱动部，但也可以是手动的驱动部。
在本实施方式中，如图4～图10所示，驱动部52具备能够正反旋转的电动机521、通过电动机521的驱动力旋转的螺纹轴522。螺纹轴522是在外周形成有外螺纹的轴构件。如上所述，螺纹轴522与设置于锁定主体51的被驱动部511的内螺纹螺合。当螺纹轴522通过电动机521的驱动力向一个方向旋转时，与螺纹轴522的共同旋转被限制的锁定主体51沿着螺纹轴522的轴向朝向锁定位置(从由图10的双点划线所示的位置朝向由实线所示的位置)移动。另外，当螺纹轴522通过电动机521的驱动力向另一个方向旋转时，锁定主体51沿着螺纹轴522的轴向朝向解锁位置(从由图10的实线所示的位置朝向由双点划线所示的位置)移动。由此，锁定主体51能够移动到锁定位置及解锁位置。
接着，对进退构件3进行更详细的说明。
如图11～图13所示，进退构件3的后退方向D2侧的端部具有在轴X方向上向后退方向D2突出的凸部3a、相对于凸部3a在前进方向D1上形成为凹状的凹部3b。凹部3b在进退构件3的绕轴X的方向上与凸部3a相邻。
凸部3a是在进退构件3的后退方向D2侧的端部相对于凹部3b在轴X方向上向后退方向D2突出的部位。凸部3a的数量没有特别限定，但在本实施方式中，如图11～图13所示，凸部3a在绕轴X的方向上设置有多个(在本实施方式中，相对于轴X对称地设置有2个)。
如图11～图13所示，凸部3a具有在进退构件3处于后退保持位置时能够与处于锁定位置的锁定构件5的被抵接部5a抵接的抵接部 CT。如后所述，在进退构件3处于后退保持位置时，在进退构件3向后退方向D2移动的情况下，通过凸部3a的抵接部CT与锁定构件5的被抵接部5a抵接，抑制进退构件3到达折回位置，限制进退构件3从后退保持位置移动到前进保持位置。
在本实施方式中，抵接部CT是凸部3a的后退方向D2侧的端部。如图19所示，在进退构件3处于后退保持位置时，在进退构件3欲向后退方向D2移动时，抵接部CT与位于锁定位置的锁定构件5的被抵接部5a抵接。此外，进退构件3被保持在后退保持位置时的进退构件3的抵接部CT与被抵接部5a之间的轴X方向的间隔被设定为进退构件3不能到达折回位置的间隔。由此，如后所述，进退构件3不能到达折回位置，限制进退构件3从后退保持位置移动到前进保持位置。
另外，如图17～图19所示，在进退构件3从前进保持位置经由折回位置向后退保持位置移动时，凸轮机构C以即使锁定构件5位于锁定位置，抵接部CT也不会与锁定构件5的被抵接部5a抵接的方式引导进退构件3。由此，如后所述，在锁定构件5位于锁定位置的情况下，进退构件3虽不能从后退保持位置移动到前进保持位置，但能够从前进保持位置移动到后退保持位置。此外，如图17～图19所示，凸部3a以在进退构件3从前进保持位置经由折回位置向后退保持位置移动时，在进退构件3绕轴X旋转时，不与位于锁定位置的锁定构件5碰撞的方式突出。凸部3a的绕轴X的方向的宽度只要构成为在位于后退保持位置的进退构件3向后退方向D2移动时与位于锁定位置的锁定构件5的被抵接部5a抵碰，就没有特别限定。
如图11～图13所示，凹部3b是在进退构件3的后退方向D2侧的端部相对于凸部3a在轴X方向上向前进方向D1凹陷的部位。通过凹部3b，在相对于凸部3a在绕轴X的方向上相邻的区域形成有凹状空间SP(参照图11)。在本实施方式中，凹部3b在绕轴X的方向上设置于一对凸部3a之间，在一对凸部3a之间形成有凹状空间SP。在本 实施方式中，凹部3b在绕轴X的方向上设置有多个(在本实施方式中，相对于轴X对称地设置有2个)。
虽详细内容后述，但凹部3b构成为，在锁定构件5位于锁定位置，并且进退构件3从前进保持位置到达折回位置时，锁定构件5配置于凹状空间SP内(参照图17及图18)。在本实施方式中，凹部3b以在从前进保持位置到达折回位置时能够将包含锁定构件5的被抵接部5a的部分收容在凹部3b的凹状空间SP这样的绕轴X的方向的宽度及轴X方向的深度形成。另外，在本实施方式中，凹部3b以在进退构件3朝向后退保持位置在绕轴X的方向上向一个方向D3旋转时锁定构件5不与凸部3a抵碰这样的绕轴X的方向的宽度及轴X方向的深度形成。
如图17及图18所示，在本实施方式中，在锁定构件5位于锁定位置且进退构件3从前进保持位置到达折回位置时，进退构件3的抵接部CT位于在轴X方向上不与被抵接部5a相对的位置，锁定构件5配置在凹状空间SP内。但进退构件3从前进保持位置到达折回位置时，如图17及18所示，凸部3a的抵接部CT在轴X方向上到达比被抵接部5a靠后退方向D2侧的位置，但抵接部CT位于在轴X方向上不与被抵接部5a相对的位置、即在绕轴X的方向上错开的位置。由此，在进退构件3从前进保持位置向折回位置移动时，处于锁定位置的锁定构件5的被抵接部5a与进退构件3的抵接部CT不抵接。另外，位于锁定位置的锁定构件5进入凹状空间SP内，因此在凹部3b的位置，被抵接部5a与进退构件3也不会接触。因此，进退构件3向后退方向D2的移动不会受到阻碍，进退构件3能够到达折回位置。因此，进退构件3能够到达折回位置，能够移动到后退保持位置。这样，即使在锁定构件5处于锁定位置的情况下，也能够进行进退构件3从前进保持位置到后退保持位置的操作。
另外，如图19所示，在进退构件3从折回位置绕轴X旋转而被保持在后退保持位置时，进退构件3的抵接部CT位于在轴X方向上与 处于锁定位置的锁定构件5的被抵接部5a相对的位置。另外，进退构件3保持在后退保持位置时的抵接部CT与被抵接部5a之间的轴X方向的间隔G1设定为进退构件3不能从后退保持位置到达折回位置的距离。此外，间隔G1只要是进退构件3不能从后退保持位置到达折回位置的距离，就没有特别限定，例如，优选进退构件3保持在后退保持位置时的抵接部CT与被抵接部5a之间的轴X方向的间隔G1(参照图19)小于进退构件3位于后退保持位置时的第一凸轮面Ca与第一接触面Cd1之间的轴X方向的间隔G2(参照图19)。在该情况下，能够更可靠地抑制进退构件3到达折回位置。
如上所述，在进退构件3保持在后退保持位置时，抵接部CT与被抵接部5a相对，抵接部CT与被抵接部5a之间的间隔G1设定为进退构件3不能到达折回位置的距离。由此，如图19所示，即使进退构件3向后退方向D2移动，进退构件3也不能到达折回位置。因此，进退构件3不能从后退保持位置移动到前进保持位置，能够通过锁定构件5将进退构件3锁定在后退保持位置。
另外，无论进退构件3的轴X方向的位置如何，锁定构件5都能够使锁定构件5移动到锁定位置。具体而言，如图13所示，在进退构件3处于前进保持位置时，进退构件3位于前进方向D1侧，在后退方向D2侧形成大的空间，因此能够使锁定构件5从解锁位置移动到锁定位置。另外，如图15所示，在进退构件3处于后退保持位置时，在凸部3a的抵接部CT的后退方向D2侧，形成有能够使锁定构件5移动到锁定位置的空间，能够以锁定构件5的被抵接部5a与进退构件3的抵接部CT相对的方式使锁定构件5移动到锁定位置。因此，无论进退构件3的轴X方向的位置如何，都能够使锁定构件5移动到锁定位置。
另外，在进退构件3处于前进保持位置的状态下使锁定构件5移动到锁定位置的情况下，如图17及图18所示，在进退构件3从前进保持位置到折回位置之间，抵接部CT与被抵接部5a在轴X方向上不 相对。然后，如图18及图19所示，通过进退构件3绕轴X旋转，在从折回位置到后退保持位置的移动过程中，抵接部CT转移到与被抵接部5a在轴X方向上相对的位置。因此，即使在前进保持位置使锁定构件5移动到锁定位置，进退构件3也能够移动到后退保持位置，并且在移动到后退保持位置的时间点，锁定构件5对进退构件3的锁定完成。因此，与以往那样在进退构件处于前进保持位置时不能进行锁定构件的锁定动作，如果不使进退构件移动到后退保持位置则无法进行锁定动作的情况不同，本实施方式的进退移动装置1能够简单地进行进退构件3的锁定。
接着，列举进退移动装置1适用于盖开闭装置D的示例，对本实施方式的进退移动装置1的动作进行说明。此外，以下的说明只不过是一例，本发明不被以下的说明限定。
如图15、图19所示，盖L(参照图3)被闭锁的状态与进退部材3位于后退保持位置的状态对应。在图19所示的状态下，由于进退构件3向前进保持位置的移动被锁定构件5限制，因此盖L的打开被锁定。为了从该状态进行供油等，在打开盖L的情况下，首先解除锁定构件5的锁定状态。具体而言，使用远程钥匙等操作单元，如图15所示，使锁定构件5移动到解锁位置(例如，向驱动部52发送解锁信号，通过驱动部52使锁定主体51移动到解锁位置)。当锁定构件5移动到解锁位置时，通过按压盖L，能够打开盖L。
当按压盖L时，进退构件3被盖L向后退方向D2按压而向后退方向D2移动。在进退构件3从后退保持位置向后退方向D2移动时，如图16所示，被引导部Cd的第一接触面Cd1与第一凸轮面Ca接触的同时，被引导部Cd向绕轴X的方向的一个方向D3移动，从而进退构件3到达折回位置。在进退构件3到达折回位置后，在盖L的按压操作解除时，通过施力构件4的向前进方向D1的作用力，进退构件3向前进方向D1移动。在进退构件3向前进方向D1移动时，如图16所示， 被引导部Cd的第二接触面Cd2与导入部Ce接触的同时，被引导部Cd向绕轴X的方向的一个方向D3移动，从而被引导部Cd进入引导部Cc。在被引导部Cd进入引导部Cc时，通过施力构件4的作用力，进退构件3向前进方向D1移动，从而到达前进保持位置(参照图13)。在进退构件3到达前进保持位置时，如图3所示，盖L打开，能够从供油口进行供油。此外，在该状态下，由于车辆的驾驶者离开驾驶席，因此有时为了在供油过程中车辆不被盗而锁定车门。车门的锁定例如可以使用远程钥匙等操作单元发送车门的锁定信号来进行。在本实施方式中，驱动部52被控制为根据车辆的车门的锁定信号使锁定主体51移动到锁定位置。在该情况下，在盖L打开的供油过程中进行车门的锁定时，盖L成为基于锁定构件5的锁定的准备状态(参照图7及图17)，能够在闭锁了盖L的时间点完成盖L的锁定(参照图8及图19)。
在盖L打开的状态下完成供油时，关闭供油口而将盖L闭锁。在盖L被闭锁时，进退构件3被盖L向后退方向D2按压而从前进保持位置向后退方向D2移动。在进退构件3从前进保持位置向后退方向D2移动时，如图17所示，被引导部Cd的第一接触面Cd1与第一凸轮面Ca接触的同时，被引导部Cd向绕轴X的方向的一个方向D3移动，从而进退构件3到达折回位置。此时，即使在锁定构件5如图17所示那样位于锁定位置的情况下，由于进退构件3具有凹部3b，因此锁定构件5进入凹部3b的凹状空间SP内，凸部3a的抵接部CT不与锁定构件5的被抵接部5a相对，因此进退构件3能够到达折回位置。如图18所示，在进退构件3到达折回位置后，当解除盖L的按压操作时，通过施力构件4的向前进方向D1的作用力，进退构件3向前进方向D1移动。在进退构件3向前进方向D1移动时，如在图18中由双点划线所示，被引导部Cd的第二接触面Cd2与第二凸轮面Cb接触的同时，被引导部Cd向绕轴X的方向的一个方向D3移动，从而被引导部Cd与停止部ST接触而停止(参照图19)。由此，进退构件3被保持在后退保持位置。
如图19所示，在进退构件3保持在后退保持位置的状态下，进退构件3的凸部3a的抵接部CT与锁定构件5的被抵接部5a相对。在本实施方式中，抵接部CT与被抵接部5a之间的间隔G1小于第一凸轮面Ca与第一接触面Cd1之间的轴X方向的间隔G2。因此，在被引导部Cd越过停止部ST之前，凸部3a的抵接部CT与锁定构件的被抵接部5a抵接。由此，进退构件3不能到达折回位置。因此，即使盖L被按压，进退构件3也不能到达折回位置，因此能够抑制盖L打开。
