具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明，若本发明实施例中有涉及方向性指示(诸如上、下、左、右、前、后……)，则该方向性指示仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，若本发明实施例中有涉及“第一”、“第二”等的描述，则该“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。
本发明提出一种清洁设备，在一些实施例中，该清洁设备可以为扫地机器人、拖地机器人、扫拖一体机器人或擦窗机器人等等清洁用的机器人，在此不做具体限制。
请参阅图1和图2，具体地，该清洁设备包括机体200、升降装置100以及清洁件300，当清洁设备为扫地机器人时，清洁件300可以为适配该扫地机器人的地刷，当清洁设备为拖地机器人时，清洁件300可以为适配该拖地机器人的拖布，当清洁设备为擦窗机器人时，清洁件300可以为适配该擦窗机器人的抹布或纸类清洁用品等。
升降装置100安装在机体200的一侧，清洁件300安装在升降装置100的安装部21上，升降装置100用于驱动清洁件300做升降运动。需要说明的是，当清洁设备为扫地机器人、拖布机器人或扫拖一体机器人时，升降装置100一般安装在机体 200的底部，以用于驱动清洁件300在机体200的高度方向上移动，当清洁设备为擦窗机器人时，升降装置100可以安装在机体200的前侧，以用于驱动清洁件300在机体200的前后方向上移动，在清洁设备对一些间隔设置于地面且有底面清洁需求的物件(例如但不限于床、沙发等物件)进行清洁时，升降装置100也可以设置在机体200的顶部，在此不做具体限制。
在一些使用场景中，当机体200检测到自身的移动路径上摆放有如毛毯等会对清洁件300的移动造成干扰的物品时，为防止清洁件300上所携带的污渍污染到这些物品和保证机体200的顺畅移动，升降装置100可以带动清洁件300往靠近机体200的方向移动，以使清洁件300与这些物品相间隔。
在另一些使用场景中，当清洁设备完成清洁任务后，为防止清洁件300上所携带的污渍污染到清理干净的地面，升降装置100可以带动清洁件300往靠近机体200的方向移动，以使清洁件300与地面相间隔。
市面上出现了具备清洁件300升降功能的清洁设备，但是市面上的清洁设备需要设置至少两个驱动器，一个驱动器用于驱动清洁件300进行转动以进行清洁工作，另一个驱动器用于驱动清洁件300做升降运动，由于采用两个驱动器会导致机体200的体积增大，这会使得清洁设备无法进行狭窄的空间进行清洁工作，且采用两个驱动器会导致清洁设备的制造成本变高，不利于提高清洁设备在同类产品中的竞争性。
为解决上述问题，本发明提出一种升降装置100。
在本发明实施例中，如图2至图10所示，该升降装置100包括驱动电机1、转动轴2、传动组件3以及牵引件4。具体而言，在一些实施例中，升降装置100还包括壳体，该壳体用于作为驱动电机1、转动轴2、传动组件3、牵引件4以及下文所提及的开关5等部件的载体，其可以安装在机体200上，由于壳体的结构形状可根据实际使用需求而作适应性的修改，在此不做具体限定；在另一些实施例中，驱动电机1、转动轴2、传动组件3、牵引件4以及下文所提及的开关5等部件也可以直接地安装在机体200上，在此不做具体限制。
请参阅图3、图6或图8，转动轴2包括相连接的安装部21和升降驱动部22，安装部21用于与清洁件300连接。具体地，为便于清洁件300的维修与更换，安装部21与清洁件300可拆连接，在具体实施时，在一些实施例中，可以如图4所示的，在清洁件300上设置插接槽(图未标识)，安装部21的端部可拆卸地插接于该插接槽；在另一些实施例中，可以在安装部21和清洁件300中的一者设置第一磁吸件，在另一者设置与第一磁吸件磁性配合的第二磁吸件，安装部21通过第一磁吸件和第二磁吸件之间的磁吸连接而与清洁件300相装配；在又一些实施例中，可以在安装部21的端部设置可抓取清洁件300的机械爪，以抓取清洁件300并带动清洁件300移动清洁，由于实现安装部21和清洁件300之间装配的结构有很多种，在此不一一列举。
传动组件3分别与驱动电机1的输出端和转动轴2相连，以将驱动电机1的动力传递至转动轴2。在具体实施时，传动组件3可以为在驱动电机1的输出端和转动轴2之间进行传动的齿轮、齿条或者皮带等等零部件，由于实现传动的结构有很多种，在此不一一列举，只要该部件满足可将驱动电机1的转动传递至转动轴2以使转动轴2转动即可，对此不做具体限制。
牵引件4与升降驱动部22螺纹连接。
在具体实施时，在一些实施例中，升降驱动部22的周壁设有沿自身的轴线方向螺旋延伸的外螺纹(该外螺纹可如图7中所示的螺纹23)，牵引件4包括套设于升降驱动部22的筒体(图未示)，筒体的内周壁设有与外螺纹相配合的内螺纹部，筒体通过内螺纹与外螺纹之间的配合而与升降驱动部22螺纹连接。
在另一些实施例中，可以在升降驱动部22远离安装部21的一端设置螺纹孔(图未示)，牵引件4包括与螺纹孔螺纹配合的螺纹柱(图未示)，螺纹柱螺纹连接于螺纹孔中。
在又一些实施例中，请参阅图7，升降驱动部22的周壁设有沿自身的轴线方向螺旋延伸的螺纹23，牵引件4包括设于升降驱动部22的一侧的牵引滑块41，牵引滑块41的至少部分结构可滑动地设于螺纹23的沟槽231内。可以理解的是，采用牵引滑块41与螺纹23配合的方式，相较于上述两种实施例而言，能够简化牵引件4的结构，在降低牵引件4的用料成本的同时，也有利于缩小升降装置100的体积，进而有利于清洁设备进入狭窄的空间进行清洁工作。
当转动轴2在驱动电机1的驱动下沿第一旋转方向旋转时，升降驱动部22相对牵引件4转动，并沿靠近安装部21的方向移动；当转动轴2在驱动电机1的驱动下沿与第一旋转方向相反的第二旋转方向旋转时，升降驱动部22相对牵引件4转动，并沿远离安装部21的方向移动。
以升降装置100安装在机体200的底部为例，请参阅图3、图4和图5，牵引件4不动，当转动轴2沿第一旋转方向转动时，也即转动轴2在图3中绕自身的轴线逆时针旋转时，转动轴2在牵引件4的反作用力下下降，在上述牵引件4包括筒体或螺纹柱的实施例中，当转动轴2下降至清洁件300与地面接触时，转动轴2可以与筒体或螺纹柱螺纹锁紧，在清洁件300旋转拖地时，转动轴2可以与筒体或与螺纹柱一起旋转，而在上述牵引件4包括牵引滑块41的实施例中，当转动轴2下降至清洁件300与地面接触时并持续旋转的过程中，牵引滑块41可以在螺纹23最后两圈螺牙232上往复移动。
当转动轴2沿第二旋转方向转动时，也即转动轴2在图3中绕自身的轴线顺时针旋转时，转动轴2在牵引件4的反作用力下上升，在上述牵引件4包括筒体或螺纹柱的实施例中，当转动轴2上升至清洁件300与地面相间隔时，此时可通过制停驱动电机1以防止筒体或螺纹柱与转动轴2脱离配合，同理，在上述牵引件4包括牵引滑块41的实施例中，也可以在转动轴2上升至清洁件300与地面相间隔时，制停驱动电机1，以防止牵引滑块41从螺纹23靠近安装部21的一端脱出。
可以理解的是，本发明技术方案升降装置100，通过设置与转动轴2螺纹连接的牵引件4，这样，在转动轴2沿不同的旋转方向旋转时，不动的牵引件4便可通过螺纹连接处的螺牙232向转动轴2施加反作用力以带动转动轴2上升或下降，在牵引件4下降至清洁件300可进行清洁的高度时，牵引件4可与转动轴2螺纹锁紧，或者在转动轴2上最后两圈的螺牙232往复移动，以便于转动轴2持续转动以带动清洁件300旋转清洁，由此可见，本申请的设计仅通过一个驱动电机1便可实现驱动清洁件300旋转清洁，以及带动清洁件300升降的技术效果，这有利于缩小升降装置100的体积，进而缩小使用该升降装置100的清洁设备的体积，有利于清洁设 备进行狭窄的空间进行清洁和有利于降低清洁设备的制造成本。
为减少牵引滑块41与沟槽231的槽壁之间的摩擦，提高牵引滑块41在沟槽231内的滑动顺畅性，在一些实施例中，牵引滑块41上位于螺纹23的沟槽231内的部分呈圆柱状设置。
基于上述牵引件4包括牵引滑块41的实施例，进一步地，螺纹23的沟槽231靠近安装部21的一端设有限位结构221，限位结构221用于限制牵引滑块41从螺纹23的沟槽231中脱出。具体而言，当转动轴2沿第二旋转方向转动时，随着升降驱动部22向远离安装部21的方向移动，牵引滑块41和限位结构221会相互靠近，直至牵引滑块41与限位结构221相抵接，当牵引滑块41与限位结构221抵接时，此时清洁件300移动至与地面相间隔的位置，在此之后，在一些实施方式中，可以通过制停驱动电机1的方式，使转动轴2停止转动以节约能源，在另一些实施方式中，也可以不制停驱动电机1，可以将牵引滑块41可移动地安装在壳体上，以使牵引滑块41可在限位结构221的抵推下随转动轴2一起转动。可以理解的是，通过限位结构221对牵引滑块41的移动进行限制，能够有效防止牵引滑块41与螺纹23之间的配合中断，有利于保证产品运行的可靠性。
在具体实施时，该限位结构221为设置在沟槽231内的限位壁、限位凸棱或者是限位凸点等等结构，在此不作具体限制。
在一些实施例中，升降装置100还包括开关5，开关5与驱动电机1电连接，开关5在被触发时制停驱动电机1；开关5的触发位置设于转动轴2的移动路径上，在升降驱动部22沿远离安装部21的方向移动时，转动轴2可触发开关5。具体而言，当转动轴2沿第二旋转方向转动时，转动轴2会带动清洁件300远离清洁面(例如地面、玻璃表面等等)，当清洁件300移动至距离清洁面一定高度时，开关5可被转动轴2所触发，进而制停驱动电机1以节约能源。
在螺纹23的沟槽231内设置有限位结构221，以及升降装置100包括开关5的实施例中，开关5可在牵引滑块41与限位结构221抵接之前，或者是牵引滑块41刚好与限位结构221相抵接时被触发。
在具体实施时，在一些实施方式，开关5也可以为接触式开关5，例如但不限于微动开关5等，转动轴2包括从升降驱动部22的周壁凸出的触发部24，触发部24与螺纹23间隔设置；开关5具有按键51，按键51设于触发部24背向安装部21的一侧，在升降驱动部22沿远离安装部21的方向移动时，触发部24可按压按键51。可以理解的是，采用机械式的方式触发开关5，具有易于实施，操控逻辑简单等优点。值得说明的是，本申请的设计不限于此，于其他实施例中，开关5也可以是感应式开关5，例如但不限于红外线感应开关5等。
请参阅图9和图10，触发部24为套设于升降驱动部22的周壁设置的第一齿轮25；传动组件3包括与转动轴2并行延伸的第二齿轮31，第二齿轮31与驱动电机1传动连接，且第二齿轮31与第一齿轮25相啮合。可以理解的是，采用齿轮啮合进行传动的方式，具有实施简单，传动可靠性高等优点，同时，第一齿轮25一轮两用，即第一齿轮25一方面用于与传动组件3啮合传动，另一方面用于随升降驱动部22的移动而触发开关5，这样，有利于简化转动轴2的结构，便于产品的小型化设计。
值得说明的是，除了用开关5制停驱动电机1外，在一些实施例中，可以通过 在驱动电机1的输出端设置霍尔元件以计算转动轴2沿第二旋转方向的转动圈数，以在牵引滑轮快从螺纹23上脱离时，通过预设程序及时地制停驱动电机1。
升降装置100包括第一弹性件6，第一弹性件6设于升降驱动部22背向安装部21的一侧，并与升降驱动部22连接，以在升降驱动部22沿靠近安装部21方向移动时向升降驱动部22提供驱动力。具体而言，在具体实施式，该第一弹性件6可以为弹簧、橡皮筋等弹性部件。可以理解的是，在第一弹性件6的驱动下，能够使安装部21快速地靠近清洁面上，这有利于缩短清洁件300下降至清洁面所耗费的时间。
在安装第一弹性件6的过程中，在一些实施方式中，升降驱动部22背向安装部21的一端凹设有安装槽222，第一弹性件6的至少部分结构设于安装槽222内，且第一弹性件6的端部弹性抵压安装槽222的槽底壁。具体地，第一弹性件6远离安装槽222的槽底壁的一端可以与壳体相连，或者与机体200相连，在此不做限制。可以理解的是，安装槽222内的腔体可以对第一弹性件6的伸缩形变起到一定的约束作用，即是说，第一弹性件6在安装槽222的约束下仅能够在安装槽222的深度方向上形变，这有利于保证第一弹性件6的使用可靠性。当然，本申请的设计不限于此，于其他实施例中，也可以不在升降驱动部22的端部设置安装槽222，而将第一弹性件6的端部直接固定在升降驱动部22的端部上。
因为清洁面难免会存在着凹凸不平的情况，当清洁件300从低洼处移动到平坦处或陡立处时，或从平坦处或陡立处移动到低洼处时，清洁件300难免会发生抖动现象，进而带动转动轴2、牵引滑块41在可以内晃动，导致转动轴2和牵引滑块41容易与其他部件(例如壳体的内壁)发生刚性磕碰，为降低抖动所带来的不良影响，在一些实施例中，升降装置100包括第二弹性件7，第二弹性件7设于牵引件4背向安装部21的一侧，并与牵引件4连接，以使牵引件4在转动轴2的轴线方向上可移动。如此，当清洁件300发生抖动时，在第一弹性件6的弹性缓冲下，能够有效降低转动轴2往远离清洁面的方向的移动幅度，同理，在第二弹性件7的弹性缓冲下，能够有效降低牵引滑块41往远离清洁面的方向的移动幅度，进而避免转动轴2、牵引滑块41与其他部件之间的磕碰，及降低抖动过程中升降装置100所造成的噪音。
因为牵引滑块41会对转动轴2往远离清洁面的方向的移动起到限制，若当抖动力度已经能够促使第一弹性件6压缩形变，却无法促使第二弹性件7压缩形变，此时转动轴2会在牵引滑块41的限制下而无法移动，进而造成清洁件300无法通过坡度较大的清洁面，为避免上述情况的发生，于本实施例中，第一弹性件6的弹性系数大于或等于第二弹性件7的弹性系数。当然，本申请的设计不限于此，于其他实施例中，第一弹性件6的弹性系数也可以大于第二弹性件7的弹性系数。
为保证第二弹性件7能够在转动轴2的移动方向上伸缩形变，于本实施例中，牵引件4包括设于升降驱动部22的一侧的安装壳42，安装壳42形成有与升降驱动部22同向延伸的导向槽421，导向槽421在安装壳42朝向升降驱动部22的一侧敞口设置，牵引滑块41可滑动地安装于导向槽421，且牵引滑块41的部分结构通过敞口插入螺纹23的沟槽231内，第二弹性件7的至少部分结构设于导向槽421内，并与牵引滑块41连接。
本发明还提出一种清洁系统，该清洁系统包括清洁设备，该清洁设备的具体结 构可参照上述实施例，由于本清洁系统采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
具体地，该清洁系统可包括与清洁设备配套使用服务站，该服务站可供清洁设备停泊，以向清洁设备提供充电、清洁等等服务中的一者或多者。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
