技术领域
本申请涉及智能家居技术领域，尤其涉及一种过载保护装置及清洁设备。
背景技术
在机械传动过程中，主动件直接或者通过传动连接结构间接的与被动件传动连接，继而将动力传送给被动件，驱动被动件移动。如常见的清洁设备上，设置有清扫机构以及行走机构等，清扫机构用于旋转并与地面干涉，配合行走机构移动清洁设备，而进行移动清扫。诸如清扫机构、行走机构等为清洁设备上的被动件，需要主动件进行驱动。在被动件受到外力阻碍移动，或者外力撞击被动件时，主动件将过载，将会损伤主动件以及主动件和被动件之间的传动连接结构。
申请人发现，现有技术中，有采用位置检测器件进行被动件位置检测，避免位移过度导致的过载，但却无法保证外力撞击被动件时过载的发生。还有采用离合器，通过主动件和被动件之间的传动脱离而避免过载的发生，但离合器的成功分离和锁死对安装和摩擦片的性能要求均较高，会增加生产成本和难度。
申请内容
为解决上述至少一项技术问题，本申请提供一种过载保护装置及清洁设备。
一方面，本申请提供一种一种过载保护装置，包括：
第一传动件，第一传动件包括第一主体和至少一个第一作用件；

第一作用件和第二作用件其中至少一个包括作用位置和让位位置，第一作用件用于与第二作用件相互作用，以使第一作用件和第二作用件其中至少一个在作用位置和让位位置之间切换。
另一方面，本申请还提供一种清洁设备，包括如上述任一项的过载保护装置。
有益效果
本申请提出的过载保护装置及清洁设备，第一传动件连接主动件，第二传动件连接被动件，通过第一传动件的第一作用件和第二传动件的第二作用件其中至少一个可以在外力的作用下移动，继而可以实现在作用位置时，在移动方向上相互作用而同步移动，继而实现主动件和被动件之间的动力传动，而在被动件受到外力撞击或者阻碍时，第一传动件和第二传动件将会受到反向作用力，继而使得第一作用件与第二作用件之间的压力增加，使得其中至少一个移动至让位位置，使得第一作用件与第二作用件解除在移动方向上相互限位关系，并相对移动进行外部冲击力或者主动件传动位置的释放，避免主动件过载，保证传动性能。

具体实施方式
为更进一步阐述本申请为达成预定申请目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本申请提出的一种过载保护装置其具体实施方式、结构、特征及其功效，详细说明如后。
如图1所示，本申请实施例提供了一种过载保护装置，可用于各种机械设备中主动件与被动件的传动连接的使用场景，如可以用于机床、汽车、施工工具和电器设备等。如可用于电钻的钻头与驱动电机之间的传动连接，或者用于自动烹饪设备中的调料的投放轮与驱动电机之间的传动连接，又或者用于清洁设备中主动件10和被动件20之间的传动，此处不再一一例举。本申请以过载保护装置用于清洁设备为例，进行过载保护装置的具体说明。清洁设备又可称为清洁机器人、自清洁设备、清扫机、扫地机器人、洗地机或拖扫机等，可以在无使用者操作的情况下，进行自动清扫、收集杂物。被动件20为清洁设备中被移动的部件，主动件10为清洁设备中为被动件20提供移动动力的部件，主动件10用于驱动被动件20移动。主动件10可以为电机或者由电机驱动的相对被动件20主动移动的部件，如电机连接从动件，而从动件连接被动件20，电机直接驱动从动件移动，而从动件进一步驱动被动件20移动，则从动件也可以作为主动件10。移动可以是直线移动、旋转或者其他形式的移动。
结合更为具体的结构，清洁设备进一步的可以包括机器主体、运动系统、清洁系统和感测系统等，为使得清洁设备能够适应更多的清扫空间以及机体更加稳定平衡，机器主体通常呈扁平的圆形，或也可具有其他形状，如半圆形、方形等。感测系统设置于机器主体上，用于进行墙壁及障碍物的感测，并绘制地图，以及在机器主体移动清扫时，进行位置的确定。运动系统可包括多个移动轮以及移动轮驱动件，移动轮驱动件可为主动件10，移动轮则为被动件20，移动轮驱动件和移动轮通过本申请的过载保护装置传动连接，移动轮驱动件可驱动移动轮转动，继而避免移动轮受到外物阻碍旋转或者受到外力撞击导致的移动轮驱动件过载。清洁系统主要包括清洁单元、尘盒和抽风机和清洁驱动件，清洁单元可以为毛刷、胶刷等，清洁单元可为被动件20，清洁驱动件则为主动件10，清洁驱动件与清洁单元通过本申请的过载保护装置传动连接，机器主体上具有位于清洁单元后方的吸尘口，尘盒位于抽风机与吸尘口之间的风路上。清洁单元与地面具有一定的干涉，清洁单元用于在清洁驱动件的作用下旋转，在旋转过程中可将地面上的垃圾扫起，并卷带到吸尘口下方，然后被抽风机产生的向尘盒回抽的气体吸入尘盒。通过过载保护装置可避免清洁单元受到外物阻碍旋转或者受到外力撞击导致的移动轮驱动件过载。此外，根据需要，清洁单元还可以连接升降机构，继而可相对机器人主体升降，实现地面障碍物的越障以及收纳，升降机构通常包括升降部件以及升降驱动件，升降驱动件与升降部件之间可通过过载保护装置连接，继而避免升降过程中清洁单元受到阻碍以及清洁单元受到外力撞击导致的升降驱动件过载。或者，一些其他的实施方式中，清洁单元还可以分别两个清洁件，两个清洁件其中至少一个连接伸缩驱动件，继而实现清洁单元的伸缩，伸缩驱动件和清洁件之间可通过过载保护装置连接，继而避免伸缩过程中清洁单元受到阻碍以及清洁件受到外力撞击导致的伸缩驱动件过载。此外，清洁设备上还可以有其他多种主动件10和被动件20的组合，此处不再一一赘述，旨在通过传动进行动力传递的部件之间，均可通过本申请的过载保护装置传动连接。
如图1-4所示，过载保护装置包括：第一传动件100，第一传动件100包括第一主体110和至少一个第一作用件120；
第二传动件200，第二传动件200包括第二主体210和至少一个第二作用件220；
第一作用件120和第二作用件220其中至少一个包括作用位置和让位位置，第一作用件120用于与第二作用件220相互作用，以使第一作用件120和第二作用件220其中至少一个在作用位置和让位位置之间切换。
其中，第一作用件120与第一主体110连接，第一主体110用于连接主动件10，以在主动件10的驱动下在移动方向上移动。第二作用件220与第二主体210连接，第二主体210用于连接被动件20。
第一作用件120与第一主体110固定连接，可以为一体成型。在主动件10为电机的实施方式中，第一主体110可以直接连接电机的输出轴，如可采用偏心安装，第一主体110用于在主动件10的作用下旋转。或者，第一主体110可以通过齿轮和齿条的配合间接连接于电机的输出轴，如第一主体110上设置齿条，电机的输出轴连接齿轮，则第一主体110用于在主动件10的作用下直线移动。根据第一主体110的移动方式的不同，第一主体110可以为多种形状，如第一主体110用于旋转的实施方式中，第一主体110可以为近似的圆盘状；在第一主体110用于直线移动的实施方式中，第一主体110可以为条形。
第二作用件220与第二主体210固定连接，可以为一体成型。第一传动件100用于将自身的运动传递给第二传动件200，如在第一主体110用于旋转的实施方式中，第二主体210用于被动旋转，继而驱动与第二主体210连接的被动件20移动。在第一主体110用于直线移动的实施方式中，第二主体210用于被动直线移动，继而驱动与第二主体210连接的被动件20移动。被动件20与第二主体210可以为直接连接，则第二主体210旋转时，被动件20跟随旋转，第二主体210直线移动时，被动件20跟随直线移动。或者，也可以是被动件20与第二主体210之间通过齿轮和齿条配合，使得第二主体210旋转时，被动件20可以直线移动，或者，第二主体210直线移动时，被动件20可以旋转。或者，还可以是被动件20与第二主体210通过两个齿轮啮合，继而第二主体210旋转时，驱动被动件20旋转。
第一作用件120与第二作用件220其中至少一个能在作用位置和让位位置之间切换的实现，可以是借助于主体形变实现，如第一主体110局部或者全部区域具有弹性，第一作用件120在第二作用件220的作用下，挤压第一主体110，使得第一主体110产生形变，继而使得第一作用件120由作用位置移动到让位位置，或者，第一主体110通过弹性形变恢复形状，使得第一作用件120由让位位置移动到作用位置。或者，第二主体210局部或者全部区域具有弹性，第二作用件220在第一作用件120的作用下，挤压第二主体210，使得第二主体210产生形变，继而使得第一作用件120由作用位置移动到让位位置，或者，第二主体210通过弹性形变恢复形状，使得第二作用件220由让位位置移动到作用位置。或者，也可以是第一主体110和第二主体210局部或者全部区域均有弹性，第一作用件120与第二作用件220相互作用,第一作用件120与第二作用件220分别挤压或者释放第一主体110和第二主体210，以在作用位置和让位位置之间切换。或者，还可以是第一主体110和第二主体210均至少局部有弹性或者全部区域均没有弹性，而第一作用件120和第二作用件220其中至少一个本身具有弹性，则作用位置和让位位置指的是第一作用件120和第二作用件220上任意一点的位置。如第一作用件120为弹性件，第一作用件120在第二作用件220的作用下，至少自身发生形变，继而使得第一作用件120由作用位置移动到让位位置，或者，第一作用件120通过弹性形变恢复形状，使得第一作用件120由让位位置移动到作用位置。第二作用件220为弹性件的实施方式不再赘述。
如图1中所示，第二作用件220的位置包括作用位置和让位位置。作用位置时，第一作用件120与第二作用件220在移动方向上相互限位，如在第一主体110围绕转轴旋转的实施方式中，第一作用件120与第二作用件220在围绕转轴的周向上限位，继而驱动第二主体210同轴旋转。在第一主体110直线移动的实施方式中，第一作用件120与第二作用件220在直线移动的方向上限位，继而驱动第二主体210同步移动。
在第一作用件120与第二作用件220相互限位继而驱动第二主体210移动时，由于第二主体210以及被动件20具有惯性，需要一定的外力带动第二主体210以及被动件20移动，在正常传动过程中，第一作用件120与第二作用件220之间会有一定压力，但压力不至于过大。但是，当第二主体210以及被动件20在移动方向上受到阻碍，如移动到极限位置，或者外力撞击等，均会导致第一主体110和第二主体210受到的反向外力增加，这就使得第一作用件120与第二作用件220之间的压力增加，第一作用件120与第二作用件220的形状设置为，当压力增加，第一作用件120与第二作用件220之间相互作用产生使得第一作用件120与第二作用件220相互远离移动的作用力，继而推动第一作用件120与第二作用件220其中能够移动的一个或者两个移动至让位位置，使得第一作用件120与第二作用件220处于位置错开的临界位置，第一作用件120与第二作用件220相互让位，继而实现第一主体110和第二主体210中断传动，第一主体110可自由移动，如受到外力撞击瞬时快速移动，而第二主体210保持原有移动状态。或者，第一主体110可停止，如移动到极限位置，而第二主体210可继续驱动。第一作用件120与第二作用件220位于作用位置时，第一作用件120与第二作用件220的连接关系可以是嵌入连接，下文中将结合具体实施例进行详细描述。
本申请实施例提出的过载保护装置及清洁设备，第一传动件连接主动件，第二传动件连接被动件，通过第一传动件的第一作用件和第二传动件的第二作用件其中的一个可以在外力的作用下移动，继而可以实现在作用位置时，在移动方向上相互作用而同步移动，继而实现主动件和被动件之间的动力传动，而在被动件受到外力撞击或者阻碍时，第一传动件和第二传动件将会受到反向作用力，继而使得第一作用件与第二作用件之间的压力增加，使得其中至少一个移动至让位位置，使得第一作用件与第二作用件解除在移动方向上相互限位关系，并相对移动进行外部冲击力或者主动件传动位置的释放，避免主动件过载，保证传动性能。
一种实施方式中，第二作用件220的数量为多个，多个第二作用件220在移动方向上布设，且相邻第二作用件220衔接，第一作用件120脱离当前第二作用件220后，第一作用件120和第二作用件220其中至少一个由让位位置移动至作用位置，第一作用件120与当前第二作用件220的相邻第二作用件220作用；或，第一作用件120的数量为多个，多个第一作用件120在移动方向上布设，且相邻第一作用件120衔接，第二作用件220脱离当前第一作用件120后，第一作用件120和第二作用件220其中至少一个由让位位置移动至作用位置，第一作用件120与当前第一作用件120的相邻第一作用件120作用。
第二作用件220的位置包括作用位置和让位位置为例，第二作用件220在第一作用件120的作用下移动至让位位置后，第二作用件220将相对第一作用件120移动，继而将越过第一作用件120，移动至第一作用件120的一侧，为使得过载保护后，第一传动件100和第二传动件200仍可以正常传动，设置第一作用件120密排，继而在第二作用件220越过当前的第一作用件120后，可以落入与当前的第一作用件120相邻的第一作用件120内，第二作用件220将通过第二主体210的的弹性回弹回到作用位置，继而与相邻的第一作用件120继续作用而实现传动。如仍存在过载的现象，则第二作用件220将继续与第一作用件120相互挤压，使得第二作用件220又一次移动至让位位置，如此往复，直到过载消失。
在第一作用件120包括作用位置和让位位置的实施方式中，为使得第一作用件120可在作用位置和让位位置之间移动，第一主体110可以为弹性主体，如可为整体具有弹性，或者采用多种材料加工而成，连接有第一作用件120的局部区域具有弹性，继而实现第一作用件120可在作用位置和让位位置之间移动。
或者，第一主体110上开设有第一镂空，第一作用件120与第一镂空靠近第二作用件220一侧的第一主体110连接，第一镂空使得第一主体110具有弹性。第一镂空与第一作用件120可以为一一对应关系，第一镂空可以为条形或者带有弧度，第一镂空使得与第一镂空两侧的第一主体110之间有间隙，继而实现通过间隙形变，继而使得第一作用件120可在作用位置和让位位置之间移动。
在第二作用件220包括作用位置和让位位置时的实施方式中，第二主体210具有弹性，或者，如图2-4所示，第二主体210上开设有第二镂空211，第二作用件220与第二镂空211靠近第一作用件120一侧的第二主体210连接，第二镂空211使得第二主体210具有弹性。具体可参照前述第一主体110和第一作用件120的实施方式，此处不再赘述。
第一主体110可以在主动件10的驱动旋转或者直线移动，以下分别进行两种移动方式对应实施例的具体描述：
主动件10驱动第一主体110和第二主体210围绕转轴旋转的实施方式中，作用位置时，第一作用件120和第二作用件220至少在围绕转轴的周向上限位，继而使得第二主体210可以跟随第一主体110同步旋转。让位位置时，第一作用件120与第二作用件220至少在围绕转轴的周向上相互让位，以在第一主体110旋转时，允许第二主体210因到达极限位置等原因静止，或者，第一主体110静止时，允许第二主体210因受到外力冲击旋转。
可由多种结构实现第一作用件120和第二作用件220在围绕转轴的周向上相互作用，
其一，第一作用件120和第二作用件220在垂直于转轴的同一平面内分布，即第一作用件120和第二作用件220对应转轴的轴向的同一位置，但与转轴的距离不同，第一作用件120和第二作用件220其中至少一个用于在垂直于转轴的平面内靠近或者远离转轴移动，以在作用位置和让位位置之间切换。如仅第二作用件220的位置包括作用位置和让位位置，第二作用件220靠近转轴移动时，将远离第一作用件120，继而在移动到让位位置时，实现第一作用件120和第二作用件220在周向上可相对移动。
为实现第一作用件120和第二作用件220在垂直于转轴的同一平面内分布，可以采用以下两种实施方式：一种实施方式中，第一主体110上开设有第一嵌入槽111，第一嵌入槽111为圆形槽，第一作用件120设置于第一嵌入槽111的槽壁，第二作用件220位于第二主体210的周侧，第二主体210嵌入第一嵌入槽111，以使第二作用件220与第一作用件120相互作用。更为具体的，在前述第二主体210上开设至少一个第二镂空211的实施方式中，第二主体210的外轮廓为圆盘形，且外径小于第一嵌入槽111的内径，继而使得第二主体210可嵌入第一嵌入槽111，且与第一嵌入槽111的内壁之间有空隙。第二镂空211可以为弧形镂空，第二主体210与第一嵌入槽111之间的空隙，实现为第二主体210位于第二镂空211靠近第一作用件120一侧的形变提供形变空间。
第二种实施方式中，第二主体210上开设有第二嵌入槽，第二嵌入槽为圆形槽，第二作用件220设置于第二嵌入槽的槽壁，第一作用件120位于第一主体110的周侧，第一主体110嵌入第二嵌入槽，以使第一作用件120与第二作用件220相互作用。具体实现方式可参照前述第一主体110上开设有第一嵌入槽111的描述。
其二，第一作用件120和第二作用件220在转轴的延伸方向上堆叠设置。
如第一作用件120和第二作用件220在围绕于转轴的同一周面内分布，即第一作用件120和第二作用件220与转轴的距离相同，第一作用件120和第二作用件220对应转轴的轴向的不同位置，以实现在轴向上堆叠设置。第一作用件120和第二作用件220其中至少一个用于在转轴的轴向上移动，以在作用位置和让位位置之间切换。如仅第二作用件220的位置包括作用位置和让位位置，第二作用件220沿着转轴移动时，将远离第一作用件120，继而在移动到让位位置时，实现第一作用件120和第二作用件220在周向上可相对移动。
第一作用件120和第二作用件220在围绕于转轴的同一周面内分布的实施方式，可以是第一主体110和第二主体210在转轴的轴向上分布，第一作用件120和第二作用件220位于第一主体110和第二主体210之间，如第一作用件120突出于第一主体110相对第二主体210的表面，而第二作用件220突出于第二主体210相对第一主体110的表面。
一种实施方式中，第一作用件120的数量为多个，多个第一作用件120相对转轴对称布设，和/或，第二作用件220的数量为多个，多个第二作用件220相对转轴对称布设。可保证第一主体110和第二主体210的径向受力平衡，避免第一主体110和第二主体210径向上单侧受力导致的相对歪斜。一种更为具体的实施方式中，如图1-4所示，第二主体210上开设有相对转轴对称布设的两个第二镂空211，第二作用件220的位置包括作用位置和让位位置，第二作用件220的数量为两个，相对转轴对称布设，且对应于第二镂空211延伸方向的中间位置。第一主体110形态固定，第一作用件120相对第一主体110的位置固定。第一主体110上开设有嵌入槽111，第一作用件120的数量为多个，第一作用件120沿着嵌入槽111内壁的周向上布设，相邻第一作用件120紧密衔接。
主动件10驱动第一主体110和第二主体210其中之一直线移动的实施方式中，作用位置时，第一作用件120和第二作用件220至少在直线移动的方向上限位，让位位置时，第一作用件120与第二作用件220至少在直线移动的方向上相互让位。
如第一主体110和第二主体210均直线移动，则第一主体110和第二主体210可以为直条状，第一作用件120和第二作用件220均可以为多个，多个第一作用件120以紧密衔接的方式沿着第一主体110的长度方向分布，多个第二作用件220以紧密衔接的方式沿着第二主体210的长度方向分布。或者，第一主体110可以在主动件10驱动下旋转，而第二主体210用于直线移动，则第一主体110的圆盘形，而第二主体210为直条状，第一作用件120和第二作用件220均为多个，多个第一作用件120以紧密衔接的方式沿着第一主体110的周向分布，多个第二作用件220以紧密衔接的方式沿着第二主体210的长度方向分布。
第一作用件120和第二作用件220相互作用，以使第一作用件120和第二作用件220其中至少一个移动到让位位置的实现方式可以为多种，可通过第一作用件120和第二作用件220相互接触位置的面型实现。如第一作用件120包括第一作用面，第二作用件220包括第二作用面。在第一主体110和第二主体210的反向外力的作用下，第一作用面与第二作用面相对滑动，以使第一作用件120和第二作用件220其中至少一个由作用位置移动至让位位置。第一作用面与第二作用面之间相互施加的外力，应满足第一作用件120和第二作用件220相互推动以使得第一作用件120和第二作用件220相互远离。如一种实施方式中，第一作用面和第二作用面其中之一为内V形面，另一个为外V形面，内V形面与外V形面的形状相适配，作用位置时，内V形面与外V形面抵接。V面可以设置于第一作用件120和第二作用件220的端部，通过内V形面和外V形面的导向作用，迫使第一作用件120和第二作用件220其中之一向让位位置移动。
或者，另一种实施方式中，第一作用面和第二作用面其中之一为凹弧面，另一个为凸弧面，凹弧面与凸弧面的形状相适配，作用位置时，凹弧面与凸弧面抵接。如第一作用件120相背第一主体110的端部上设置有凹弧面，第二作用件220相背第二主体210的端部上设置有凸弧面，通过凹弧面和凸弧面的弧面作用，相较V形面，避免第一作用面和第二作用面上的尖角，使得第一作用件120越过第二作用件220更加顺畅，不会有尖角过度的卡顿。此外，作用位置时，第一作用面与第二作用面的面抵接，使得第一作用件120和第二作用件220之间位置更加稳定，使得第一主体110和第二主体210之间的传动更加紧密。
一种实施方式中，过载保护装置还包括传动连接件300，第一主体110上设置有传动连接件300，传动连接件300用于连接主动件10，如传动连接件300可以为偏心连接件，偏心连接件与主动件10的输出轴偏心安装，实现第一主体110与主动件10的输出轴轴向限位。
和/或，第二主体210上设置有传动连接件300，传动连接件300用于连接被动件20，如传动连接件300为齿轮，可以与被驱动件齿接。
另一方面，本申请还提供一种清洁设备，包括如上述任一项的过载保护装置，包括上述任一项过载保护装置的优点，此处不再赘述。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
