具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳的实施例。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
参考图1，本发明公开了一种具有拖地功能的清洁机器人100，其包括底盘10、驱动组件20和拖地组件30，拖地组件30、驱动组件20分别安装于底盘10。清洁机器人100可在地面移动，并利用拖地组件30实现拖地功能，以清洁地面。在一些实施方式中，清洁机器人100可包括控制器及多种传感器，传感器与控制器通信连接，以使清洁机器人100具备自动识别目标区域并自主规划清扫路径的功能。
在一实施例中，底盘10大致呈圆盘状，拖地组件30的至少部分凸出于底盘10以用于和地面接触。结合图2、图3和图4，拖地组件30包括清洁件支架31和清洁件33，清洁件33绕设于清洁件支架31。驱动组件20与清洁件支架31相联动，以驱使清洁件33绕清洁件支架31运动，并在清洁地面的过程中实现拖地功能。
参考图3，清洁件支架31包括相对的第一端31a和第二端31b，清洁件支架31能够在撑开状态和收拢状态之间切换，且在收拢状态时，第一端31a相比于撑开状态更靠近第二端31b。在撑开状态时，清洁件33撑开于第一端31a与第二端31b之间。在收拢状态时，清洁件33松弛且能够从清洁件支架31脱出。
具体地，清洁件支架31包括支架组件311和转轴313，支架组件311包括第一支架3111和第二支架3113，第一支架3111与第二支架3113活动连接以使第二支架3113能够相对第一支架3111移动，进而使得清洁件支架31在撑开状态与收拢状态之间切换。进一 步，第一支架3111与第二支架3113能够沿垂直于转轴313的轴线方向互相靠拢和相互远离，使得清洁件支架31在收拢状态与撑开状态之间切换。
在一些实施方式中，第二支架3113与第一支架3111滑动配合以使清洁件支架31能够在撑开状态和收拢状态之间切换。换言之，第一支架3111可相对第二支架3113滑动，以改变两者之间的相对位置。在收拢状态时，第一支架3111的远离第二支架3113的一端相比于撑开状态更靠近第二支架3113，或者说，第二支架3113的远离第一支架3111的一端相比撑开状态更靠近第一支架3111。简言之，撑开状态的清洁件支架31相比收拢状态占用更大的宽度。
转轴313可转动地设于第一支架3111。在一些实施方式中，转轴313设置于第一支架3111的远离第二支架3113的一端且转轴313位于整个清洁件支架31的第一端31a处，第一支架3111可以设置滚动轴承或者滑动轴承，转轴313安装于滚动轴承或滑动轴承，以使转轴313能够相对第一支架3111转动。驱动组件20的输出端连接于转轴313并用于驱使转轴313相对第一支架3111转动。在撑开状态时，第一支架3111与第二支架3113撑开清洁件33，如图2所示。清洁件33从清洁件支架31的一侧绕过第二支架3113的远离第一支架3111的一端至清洁件支架31的相对的另一侧，再绕过转轴313回清洁件支架31的一侧。在撑开状态时，第二支架3113的远离第一支架3111的一端及转轴313分别抵持清洁件33。驱动组件20驱使转轴313相对第一支架3111转动时，转轴313与清洁件33之间的摩擦力可带动清洁件33绕清洁件支架31同步运动，即实现转轴313与清洁件33之间的摩擦传动。当然，转轴313的周向也可以套设硅胶套或者橡胶套以增大转轴313与清洁件33之间的摩擦力，防止清洁件33在清洁件支架31打滑。
在另外一些实施方式中，转轴313可以不必设置于第一支架3111的远离第二支架3113的一端。例如，转轴313可设置于第一支架3111的远离第二支架3113的一端与第二支架3113之间。本发明以转轴313设于第一支架3111的远离第二支架3113的一端为例进行说明。
在收拢状态时，清洁件33松弛且能够从清洁件支架31脱出。清洁件33松弛可以简单地理解为，清洁件支架31在收拢状态时，清洁件支架31的周向的长度小于清洁件33的内侧的周长。清洁件33因松弛而与清洁件支架31之间产生间隙后，用户可以从清洁件33的端部或清洁件支架31的端部将清洁件33与清洁件支架31分离，即使得清洁件33从清洁件支架31脱出。当然，在一些实施方式中，可以将收拢状态的清洁件支架31竖直放置，使得转轴313的轴线方向与重力方向基本一致，在重力的作用下，清洁件33也可以从清洁件支架31脱出，从而可以避免手动拉伸清洁件33而带来的不便。安装清洁件33时，也可以将收拢状态的清洁件支架31穿设至清洁件33内，避免手动拉伸清洁件33带来的不便，从而提升清洁件33拆装的便捷性。
在本发明实施方式中，撑开状态和收拢状态可以理解为第一支架3111相对第二支架3113滑动的两个极限位置。在正常使用时，在撑开状态时第一支架3111不能相对第一支架3111继续做相对远离的运动；在收拢状态时第一支架3111不能相对第二支架3113继续做相对靠近的运动。
这种极限位置可以通过结构来限定。例如，参考图5，在一些实施方式中，第一支架3111和第二支架3113中的一者设有限位柱311a，另一者开设有限位孔311b，限位柱311a穿设于限位孔311b。参考图6，限位柱311a的末端可以设有限位部311c，限位部311c用于在撑开状态时与限位孔311b的端壁相抵持，以限制第一支架3111相对第二支架3113的移动范围。
在一些实施方式中，限位部311c为螺钉并螺纹连接于限位柱311a的端部，螺钉的头部的宽度大于限位孔311b的宽度。这种结构的限位部311c有利于第一支架3111与第二支架3113的组装，即在组装过程中，可以将限位柱311a插入限位孔311b内，再在限位 柱311a的端部连接限位部311c。在其他实施方式中，限位部311c可以采用其他方式制成。例如，限位部311c可以为铆压形成的结构，或者为粘接、焊接形成的结构。
继续参考图3，在一些实施方式中，清洁件支架31包括引导件315，引导件315设于第二支架3113的远离第一支架3111的一端，也即引导件315设置于支架组件311的远离转轴313的一端，引导件315位于整个清洁件支架31的第二端31b处且用于在撑开状态时引导清洁件33运动。
在本发明实施方式中，第一端31a、第二端31b可以按照以下方式理解：整个清洁件支架31大致呈矩形块状，在清洁件支架31的伸缩变形方向上，矩形块的一端为第一端31a，矩形块的相对的另一端为第二端31b。第一端31a处安装了清洁件支架31的转轴313，第二端31b处安装了清洁件支架31的引导件315。
参考图3，在一些实施方式中，引导件315呈圆柱状，其可转动地设于第二支架3113。引导件315可以为整段式的结构，即从第二支架3113的一端沿平行于转轴313的轴线方向(图中Y轴方向)延伸至第二支架3113的相对的另一端。参考图7，在另一些实施方式中，引导件315也可以为分段式的结构，即引导件315可以设置为两段以上，两段以上的引导件315分别与第二支架3113转动连接。图7即示出了引导件315设置为两段的情形。当然，可以理解的是，转轴313也可以采用类似结构，即转轴313也不限于整段式结构，转轴313也可以设置两段以上。
清洁件支架31在撑开状态时，引导件315与转轴313分别与清洁件33相抵持，转轴313带动清洁件33绕清洁件支架31运动时，清洁件33带动引导件315相对第二支架3113转动，从而利用滚动摩擦减小清洁件33在清洁件支架31的运动阻力。在这种实施方式中，引导件315的周向表面可以呈光滑的圆柱面状，也可以设置防滑纹路。在这种实施方式中，可转动的引导件315通过实体轴实现与第二支架3113的转动连接。换言之，引导件315与第二支架3113的转动连接可简单地理解为：引导件315与第二支架3113中的一者设有转轴，另一者设有轴孔，转轴与轴孔转动配合以实现两者的转动连接。
当然，引导件315还可以为轮或者辊等结构，其能够相对第二支架3113转动即可。
参考图8、图9和图10，在另一些实施方式中，引导件315可滚动地设于第二支架3113。换言之，可滚动的引导件315不需设置实体轴。在这种实施方式中，引导件315可包括一个或者两个以上的滚动体例如滚珠或者滚柱，滚动体可滚动地设于第二支架3113的远离第一支架3111的一端。在滚动体设置为两个以上的实施方式中，两个以上的滚动体可以沿平行于转轴313的轴线方向间隔分布。图8示出了引导件315包括三个以上滚珠的情形，图9示出了引导件315包括三个以上滚柱的情形，图10则示出了引导件315包括两个滚柱的情形。在其他实施方式中，滚柱可设置为一个，且滚柱可沿平行于转轴313的方向从第二支架3113的一端延伸至相对的另一端。
清洁件支架31处于撑开状态时，滚动体可与清洁件33的内侧相抵接。在转轴313带动清洁件33绕清洁件支架31运动的过程中，清洁件33能够带动滚动体在第二支架3113滚动，滚动体与清洁件33之间的滚动摩擦也能够减小清洁件33的运动阻力。
参考图11，在其他实施方式中，引导件315可以缺省，第二支架3113的远离第二支架3113的一端构成第二端31b，且第二端31b处设有引导弧面3113a，引导弧面3113a用于在撑开状态时引导清洁件33运动即可。在这种实施方式中，第二支架3113的远离第一支架3111的一端可以加工成圆柱面，圆柱面的表面粗糙度可以设置得相对较小，圆柱面构成引导弧面3113a的部分或全部，且引导弧面3113a的轴线方向平行于转轴313的轴线方向。
换言之，在支架组件311的厚度方向上，引导弧面3113a的一端与第二支架3113的上侧表面相连，引导弧面3113a的相对的另一端与第二支架3113的下侧表面相连。进一步，引导弧面3113a的与第二支架3113的上侧表面相连的一端可以与第二支架3113的上 侧表面相切，以使清洁件33在运动过程中可以在第二支架3113的上侧表面与引导弧面3113a之间平稳地滑动，改善清洁件33的在第二端31b处的受力，防止清洁件33在运动过程中出现抖动。当然，引导弧面3113a的与第二支架3113的下侧表面相连的一端也可以与第二支架3113的下侧表面相切，以使清洁件33在运动过程中可以在第二支架3113的下侧表面与引导弧面3113a之间平稳地滑动，改善清洁件33的在第二端31b处的受力，防止清洁件33在运动过程中出现抖动。
在清洁件支架31处于撑开状态时，清洁件33与引导弧面3113a相抵接并可被转轴313带动而相对引导弧面3113a滑动，表面粗糙度较小的引导弧面3113a也可以减小清洁件33绕清洁件支架31的运动阻力。
第一支架3111与第二支架3113能够沿垂直于转轴313的轴线方向互相靠拢和相互远离的配合方式由很多种结构形似，例如第一支架3111与第二支架3113滑动配合。再参考图5和图6，在一些实施方式中，第一支架3111和第二支架3113中的一者设有凸块311d，另一者开设有凹槽311e，凸块311d滑动配合于凹槽311e。换言之，第一支架3111可以设有凸块311d，第二支架3113设有与凸块311d滑动配合的凹槽311e。第一支架3111也可以设有凹槽311e，第二支架3113设有与凹槽311e滑动配合的凸块311d。当然，第一支架3111可以既设置凸块311d，又设置凹槽311e，第二支架3113对应第一支架3111的凸块311d的位置设有与凸块311d滑动配合的凹槽311e，第二支架3113对应第一支架3111的凹槽311e的位置则设有与凹槽311e滑动配合的凸块311d。
在一些实施方式中，如图5所示，凸块311d大致呈矩形盒状并沿第一支架3111相对第二支架3113的滑动方向延伸，凹槽311e与凸块311d的形状匹配。这种结构的凸块311d在平行于转轴313的轴线方向上可以具有相对较大的宽度，以提升凸块311d与凹槽311e的槽壁的接触面积，进而提升第一支架3111相对第二支架3113的滑动稳定性。
凸块311d与凹槽311e的配合还可对第二支架3113相对第一支架3111的滑动起到导向和限位作用，防止第一支架3111在相对第二支架3113的滑动过程中发生偏斜。在另一些实施方式中，凸块311d可以采用直条状的筋条代替。参考图12和图13，在一些实施方式中，第二支架3113设置沿第一支架3111相对第二支架3113的滑动方向延伸的筋条311f，第一支架3111设置与筋条311f匹配的条形槽311g即可。当然，筋条311f可以设置于第二支架3113，第一支架3111设置与筋条311f匹配的条形槽311g；或者第一支架3111设置有筋条311f和条形槽311g，第二支架3113的与第一支架3111的筋条311f对应的位置设有用于与筋条311f滑动配合的条形槽311g，第二支架3113的与第一支架3111的条形槽311g对应的位置设有与条形槽311g滑动配合的筋条311f即可。
在参考图5和图6，清洁件支架31可以包括第一复位件316，在收拢状态时，第一复位件316的一端抵持于第一支架3111，第一复位件316的相对的另一端抵持于第二支架3113，以使第一支架3111与第二支架3113具有相对远离的运动趋势。第一复位件316可以为弹簧，或者弹片，或者弹性柱。
在清洁件支架31设有凸块311d和凹槽311e的实施方式中，如图5所示，在收拢状态时，第一复位件316的一端可以抵持于凸块311d，第一复位件316的相对的另一端可以抵持于凹槽311e的槽壁，以使第一支架3111与第二支架3113具有相对远离的运动趋势。
在另一些实施方式中，如图6所示，第一支架3111和第二支架3113中的至少一者设有凸柱311h，第一复位件316套设于凸柱311h。在收拢状态时，第一复位件316的一端抵持于第一支架3111，第一复位件316的相对的另一端抵持于第二支架3113。换言之，第一支架3111可以设置凸柱311h，或者第二支架3113设置凸柱311h，或者第一支架3111、第二支架3113均设置凸柱311h，第一复位件316套设于凸柱311h，以利用凸柱311h对第一复位件316的伸缩起到限位和导向作用。在第一支架3111、第二支架3113均设置凸 柱311h的实施方式中，第一支架3111的凸柱311h与第二支架3113的对应位置的凸柱311h可以相对接，以用于套设第一复位件316。
第一复位件316的一端可以连接于第一支架3111，相对的另一端可以连接于第二支架3113，在撑开状态时，第一复位件316可以处于压缩量相对较小的状态，使得第二支架3113的远离第一支架3111的一端及转轴313能够可靠地抵持于清洁件33，从而在清洁件33内形成适宜的张紧力，以利于清洁件33绕清洁件支架31的运动，防止清洁件33在清洁件支架31打滑。在另一些实施方式中，在撑开状态时，第一复位件316可以处于无压缩状态即自然状态。
可以理解的是，第一复位件316的端部无需与第一支架3111或者第二支架3113固定连接。例如，在一些实施方式中，在撑开状态时，第一复位件316的端部无需抵持于第一支架3111或第二支架3113，在清洁件支架31处于收拢状态时，第一支架3111与第二支架3113压缩第一复位件316以使第一支架3111与第二支架3113具有相对远离的运动趋势即可。
再参考图4，清洁件支架31可以包括滑块317，滑块317滑动配合于第一支架3111和第二支架3113中的一者，第一支架3111和第二支架3113中的另一者开设有卡槽311k。在清洁件支架31从撑开状态向收拢状态切换的过程中，滑块317能够进入卡槽311k，以使清洁件支架31保持在收拢状态。
清洁件支架31可以包括第二复位件318，第二复位件318、滑块317设于第一支架3111和第二支架3113中的同一者，且第二复位件318与滑块317相抵持。换言之，滑块317与第二复位件318可以均设于第一支架3111，也可以均设于第二支架3113。在清洁件支架31从撑开状态向收拢状态切换的过程中，第二复位件318用于驱使滑块317进入卡槽311k。
第二复位件318可以为弹簧，也可以为弹片或者弹性柱。参考图4，在一实施例中，第二复位件318、滑块317均设于第二支架3113，卡槽311k设于第一支架3111的凸块311d。第二复位件318的一端抵持于第二支架3113，第二复位件318的相对另一端抵持于滑块317。在第一复位件316与第二复位件318从撑开状态向收拢状态切换即第一支架3111与第二支架3113做相对靠近运动时，第一支架3111抵压滑块317，以使滑块317沿平行于转轴313的轴线方向向外运动时，滑块317压缩第二复位件318，第二复位件318积蓄弹性势能；当滑块317在第一支架3111相对第二支架3113的移动方向移动至卡槽311k所在位置时，第二复位件318释放弹性势能，滑块317进入卡槽311k内。滑块317与卡槽311k的配合即可限制第一支架3111相对第二支架3113的移动，以使清洁件支架31保持在收拢状态，以便于清洁件33的拆装。
进一步，结合图14，第一支架3111、滑块317中的至少一者具有第一导向面A1。第一导向面A1可以为平面且与转轴313的轴线方向以及第二支架3113相对第一支架3111的移动方向倾斜设置。在清洁件支架31从撑开状态向收拢状态切换的过程中，第一支架3111、滑块317于第一导向面A1处相抵持，进而可驱使滑块317在平行于转轴313的轴线方向上向第二支架3113外侧移动并压缩第二复位件318。在滑块317沿第一支架3111相对第二支架3113的移动方向运动至卡槽311k后，第二复位件318即可驱使滑块317进入卡槽311k，从而使得清洁件支架31保持在收拢状态。
在滑块317设置于第二支架3113的实施方式中，清洁件支架31可以包括按键3193，按键3193设于第二支架3113。在清洁件支架31处于收拢状态时，按键3193用于被按压并与滑块317相抵持，以驱使滑块317在平行于转轴313的轴线方向上移动并退出卡槽311k。
结合图14和图15，在按键3193被按压过程中，按键3193用于和滑块317抵接并驱使滑块317退出卡槽311k，以解除清洁件支架31的收拢状态，即使得第二支架3113能 够再次相对第一支架3111移动。
在清洁件支架31处于收拢状态时，滑块317与卡槽311k的配合实现了第一支架3111与第二支架3113的卡合。按压按键3193时，按键3193向滑块317方向缩进，以使滑块317退出卡槽311k。滑块317退出卡槽311k后，在第一复位件316的作用下，第一支架3111与第二支架3113做相互远离运动，进而可以回复至撑开状态。
参考图16，在另一实施例中，滑块317、第二复位件318设于第一支架3111，按键3193、卡槽311k设于第二支架3113，按键3193可沿Y轴方向伸缩移动。第二支架3113可以开设容置槽(图未标)，按键3193滑动配合于容置槽。清洁件支架31还可以包括回位件3115，回位件3115设于第二支架3113，且回位件3115可以为弹簧且一端抵持于按键3193，相对的另一端抵持于第二支架3113。在清洁件支架31处于收拢状态时，按键3193用于被按压并在平行于转轴313的轴线方向上移动，以与滑块317相抵持，并驱使滑块317退出卡槽311k，在第一复位件316的作用下，第一支架3111能够相对第二支架3113移动并切换至撑开状态。按键3193被按压后，回位件3115被压缩而积蓄弹性势能，在释放按键3193后，回位件3115驱使按键3193在第二支架3113复位。
在其他实施方式中，回位件3115可以为弹片或者弹性柱，此处不再赘述。滑块317与卡槽311k的配合结构与在前的实施例类似，此处不再赘述。
在一些实施方式中，底盘10还可以开设卡孔(未图示)，清洁件支架31安装在底盘10时，按键3193穿设于卡孔，使得拖地组件30被进一步限位在底盘10。在需要将拖地组件30从底盘10拆下时，用户可以按压按键3193，以使按键3193从卡孔退出，再将整个拖地组件30绕第一支架3111和第二支架3113中的一者的端部旋转，再将另一者从底盘10拆离，即可将拖地组件30从底盘10拆下。例如用户按压按键3193后，可以将整个拖地组件30绕第一支架3111旋转以使得第二支架3113所在端远离底盘10，再将第一支架3111从底盘10拆离。这种结构可以提升拖地组件30与底盘10拆装的便利性。
参考图17和图18，在一实施例中，清洁件33呈环状且用于绕设置清洁件支架31，清洁件33的用于接触地面的一侧可以设置软毛，软毛可以带动平坦地面上的灰尘向底盘10的吸尘口移动，进而对地面进行清洁。具体地，在一些实施方式中，清洁件33的背向清洁件支架31的一侧包括布质材料。在这种实施方式中，清洁件33可以包括内圈和环绕于内圈外侧并与内圈连接的外圈，外圈为布质材料，内圈为柔性体和弹性体中的至少一种。内圈呈闭合的环状且可用于绕设至清洁件支架31。
参考图19和图20，在另一实施例中，清洁件33为柔性体且包括主体331和凸设于主体331的刮条333，也即主体331和刮条333可以均为柔性体。主体331呈环状且绕设于清洁件支架31，刮条333位于主体331的背向清洁件支架31的一侧，也即刮条333位于主体331的外侧。刮条333可以设置为多条且多条刮条333沿清洁件33在清洁件支架31的运动方向间隔排布，也即刮条333沿主体331的环形延伸方向间隔排布。刮条333可以间隔均匀地排布于主体331的表面，也可以不均匀的设置于主体331的表面。
相关技术中，配备有清洁件33的清洁机器人100的清洁件33表面一般为软毛，清洁机器人100在清洁毛毯等粗糙表面时，表面为软毛的清洁件33难以扬起毛毯等粗糙表面的灰尘，造成清洁效率偏低，清洁机器人100的适用环境也受到了限制。
采用包括主体331和刮条333结构的清洁件33后，由于主体331和刮条333均为柔性体，在清洁机器人100清洁地面的过程中，清洁件33被驱使相对底盘10运动，且清洁件33相对地面运动，刮条333可以拍打毛毯等粗糙表面，进而扬起毛毯等粗糙表面的灰尘，且刮条333可以带动灰尘向底盘10的吸尘口移动，进而对毛毯等粗糙表面进行更有效地清洁。当然，设有刮条333的清洁件33同样可以对平坦地面进行有效清洁。
参考图21，在一些实施方式中，主体331可以包括内圈3311和环绕于内圈3311外且与内圈3311连接的外圈3313，外圈3313的材质与内圈3311的材质可以相同，刮条333 设置于外圈3313的背向内圈3311的一侧。例如，内圈3311的材质可以为硅胶或橡胶等材质，外圈3313的材质可以和内圈3311相同。当然，外圈3313的材质可以和内圈3311不同，例如内圈3311的材质为硅胶或橡胶等材质，外圈3313为其他类型的软胶材质。内圈3311的材质的弹性系数可以小于外圈3313，也即内圈3311可以更加柔软、易变形而套设至清洁件支架31上。当然，内外圈3313的设置不是必须的，内圈3311和外圈3313中的一者可以缺省。
主体331与刮条333可以一体成型，且为弹性体，这种结构可以提升清洁件33加工的便利性。在主体331无内圈3311的实施方式中，刮条333与主体331一体成型即可。在主体331包括内圈3311和外圈3313的实施方式中，主体331可以与外圈3313一体成型。
参考图22，在一些实施方式中，在平行于转轴313的轴线方向上，刮条333延伸呈V形。换言之，在平行于清洁件33的绕设轴线方向上，刮条333延伸呈V形。在清洁件33安装于清洁件支架31且拖地组件30安装于底盘10后，V形状的刮条333的开口可以朝向清洁机器人100的前进方向，以使扬起的灰尘具有向V形“尖端”集中的趋势，进而便于刮条333收集灰尘，提升清洁机器人100的清洁效率。可以理解的是，清洁机器人100的前进方向可简单地理解为清洁机器人100正常工作时的行进方向，本发明所指出的前进方向仅用于示例说明。
进一步，在一些实施方式中，清洁件33相对清洁件支架31的绕行方向可以与清洁机器人100的前进方向相反。换言之，V形状的刮条333的开口朝向可以与清洁件33相对清洁件支架31的绕行方向相反。例如，清洁机器人100可相对于地面以速度V1向前移动，即底盘10相对于地面以速度V1向前移动。驱动组件20驱使转轴313转动，带动清洁件33绕清洁件支架31运动，清洁件33与地面贴合的一侧相对于地面向后移动的速度为V2。由于清洁件33通过清洁件支架31安装于底盘10上，清洁件33与地面贴合的一侧相对于地面的移动速度即可达到(V1+V2)。相比于底盘10的前进方向与清洁件33相对地面的移动方向一致的情况，上述设置方式在相同的时间内清洁件33可以相对地面移动更长的距离，因而可以提高清洁机器人100的清洁效率。
在其他实施方式中，在平行于转轴313的轴线方向上，刮条333可以延伸呈波浪形，或直条形。换言之，在平行于清洁件33的绕设轴线方向上，刮条333可以延伸呈波浪形，或直条形。这类刮条333的设置同样可以扬起毛毯等粗糙表面的灰尘，进而对毛毯等粗糙表面进行更有效地清洁以提升清洁效率。
在一些实施方式中，在平行于转轴313的轴线方向上，任一刮条333从主体331的一端延伸至主体331的相对的另一端。在其他实施方式中，刮条333的相对的两端可以与主体331的同侧边缘存在间隔。
可以理解的是，在清洁件33包括主体331和凸设于主体331的刮条333的实施方式中，清洁件支架31可以不具备可相对滑动的第一支架3111和第二支架3113。换言之，在清洁件33包括主体331和凸设于主体331的刮条333、清洁件33与清洁件支架31组合形成拖地组件30并应用于清洁机器人100的实施方式中，清洁件支架31不限于能够在撑开状态和收拢状态之间切换的结构形式。由于清洁件包括主体331和刮条333，在清洁机器人100清洁地面的过程中，刮条333可以拍打毛毯等粗糙表面，进而对毛毯等粗糙表面进行更有效地清洁。当然，设有刮条333的清洁件33同样可以对平坦地面进行有效清洁。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能 因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
