手推式割草机100还设置有控制装置16，用于控制马达14的运转，包括控制马达14启动、停止以及调节马达14的转速等。在一些实施例中，控制装置16包括与马达14实现电连接或者通信连接的操作开关，用于可以通过操作操作开关使得马达14启动或者停止转动。控制装置16还包括供用户操作以调节马达14转速的调速开关；作为一种可选择的实施方式，操作开关和调速开关集成为一个操作件。作为一种可选方式，控制装置16还包括信号收发装置，用于接收操作开关发出的信号并传递给马达14，马达14对该信号作出相应的反应。控制装置16还包括启动模块，启动模块能发出一个控制马达14正转的第一信号且能发出一个控制马达14停止转动的第二信号；控制装置16还包括控制模块，控制模块在启动模块发出第二信号时控制马达14在一个预设时长内反转，预设时长约为2秒至20秒，可选为5秒。在一些实施例中，控制模块与操作开关构成通信连接或电连接。当用于操作操作开关时，操作开关向控制模块发出信号，控制模块控制马达14响应。
本实施例中采用如下控制方式实现离合件151状态的切换：当用户触发操作开关时，操作开关向电控元件发出信号，电控元件接收到该信号后控制马达14正转，也即是绕第一轴线101沿第一方向11’转动；当用户释放操作开关，操作开关向电控元件发出信号，电控元件则控制马达14反转，也即是绕第一轴线101沿第二方向转动，从而实现离合件151在第一位置和第二位置之间切换；也即是说，在此控制方式下，只要用户释放操作开关，轮子13便能相对于马达轴141自由转动，此时在不触发操作开关的前提下用户可手推机器前进或者后退。 作为一种可选择的实施方式，操作开关具有分别控制马达14正转和反转的两个档位；作为另一种可选择的实施方式，控制装置16还包括独立与操作开关的用于控制电机反转的第二开关。操作开关和第二开关的结构，可以是扳机、拨扭等形式的机械开关也可以是信号开关。
传动装置15包括主动件152和从动件153，主动件152直接或间接连接至马达轴141且被马达轴141驱动，从动件153直接或间接连接至轮子13且驱动轮子13，主动件152驱动从动件153转动；在一些实施例中，传动装置15为齿轮传动；在一些实施例中，主动件152为直齿轮，从动件153为棘轮。离合件151用于实现主动件152和从动件153之间的动力传动；在离合件151位于第一位置时，离合件151允许主动件152将动力传输至从动件153，在离合件151位于第二位置时，离合件151断开马达14和轮子13之间的动力的传递路径；在一些实施例中，当离合件151处于第一位置，离合件151连接主动件152和从动件153；当离合件151处于第二位置，离合件151不连接主动件152和从动件153；在一些实施例中，当离合件151处于第二位置，离合件151不与主动件152或者从动件153相连。本实施例中，离合件151可转动地安装至主动件152，当离合件151处于第一位置，离合件151同时接触至从动件153，当离合件151处于第二位置，离合件151与从动件153脱离。
如图5至图8所示，在一些实施例中，离合件151包括连接部151a和活动部151b；活动部151b连接至连接部151a，连接部151a连接至主动件152；当离合件151在第一位置和第二位置之间切换时，马达14驱动主动件152转动，连接部151a与主动件152构成同步转动；活动部151b相对主动件152发生相对运动。在一些实施例中，活动部151b具有断开位置和驱动位置，分别对应离合件151的第一位置和第二位置；活动部151b在断开位置和驱动位置之间切换使得离合件151能够在第二位置和第一位置之间切换；在一些实施例中，当马达14沿第一方向11’转动时，离合件151由第二位置被切换至第一位置，活动部151b相对主动件152由断开位置运动至驱动位置；当马达14沿第二方向转动时，离合件151由第一位置被切换至第二位置，活动部151b相对主动件152由驱动位置运动至断开位置。当活动部151b处于驱动位置时，马达轴141能够驱动轮子13转动，当活动部151b处于断开位置时，轮子13能相对于马达轴141自由转动。
马达14可以直接通过马达轴141驱动主动件152转动，也可以通过其他传动结构驱动主动件152。连接部151a与主动件152构成活动连接，活动部151b与连接部151a一体成型或构成固定连接；作为一种可选择的实施方式，连接部151a与主动件152构成固定连接，活动部151b与连接部151a构成活动连接。在本实施例中，连接部151a与主动件152构成转动连接，活动部151b与连接 部151a一体成型或者构成固定连接。
离合件151还包括驱动部151c，当离合件151在第一位置和第二位置之间切换时，驱动部151c驱动活动部151b相对主动件152运动。也即是说，当离合件151在第一位置和第二位置之间切换时，马达14沿第一方向11’转动以驱动主动件152转动，主动件152的转动带动驱动部151c运动，进而驱动部151c驱动活动部151b相对主动件152运动，从而实现活动部151b在驱动位置和断开位置之间的切换。在一些实施例中，驱动部151c与活动部151b构成联动；在主动件152沿第一方向11’转动时，驱动部151c自发运动至与活动部151b的驱动位置相对应的位置；在主动件152沿第二方向转动时，驱动部151c自发运动至与活动部151b的断开位置相对应的位置。需要说明的是，如果活动部151b本身处于驱动位置，主动件152沿第一方向11’转动时，驱动部151c则不发生位移；如果活动部151b本身处于断开位置，主动件152沿第二方向转动时，驱动部151c也不发生位移。
传动装置15还包括用于容纳主动件152和从动件153的壳体154，在轴向上壳体154安装至轮子13的一侧，壳体154与主动件152和从动件153在轴向上位于轮子13的同侧。壳体154包括一个与驱动部151c接触的接触面154a，在本实施例中，接触面154a为壳体154的一个端面，端面在垂直于轴向的平面内延伸。
本实施例中离合件151在第一位置与第二位置之间切换的运动原理如下：马达轴141沿第一方向11’转动时，主动件152被马达轴141驱动，由于连接部151a连接至主动件152并与主动件152同步转动，驱动部151c在连接部151a的拉力和接触面154a的摩擦力的合力作用下相对主动件152运动，从而带动活动部151b相对主动件152运动。驱动部151c在转动过程中所受到的接触面154a的摩擦力和连接部151a的拉力的方向不断发生变化导致驱动部151c的受力不断变化，在无其他阻挡的情况下驱动部151c将运动至受力平衡的平衡位置为止。在驱动部151c运动至平衡位置之前，活动部151b在驱动部151c的驱动下运动至驱动位置，受到从动件153的阻力不再继续运动，驱动部151c受到活动部151b的阻力也停止运动。反之，当马达轴141沿第二方向转动时，驱动部151c在连接部151a的拉力和接触面154a的摩擦力的作用下相对主动件152运动，从而带动活动部151b发生相对运动，脱离与从动件153的接触，运动至断开位置。需要说明的是，活动部151b不与从动件153构成连接或接触的任意位置均为断开位置。
为了说明驱动部151c和活动部151b相对主动件152发生的运动的原理，采用以下原理模型进行解释：
如图9所示，在虚线矩形框所示的竖直面10’内有连杆机构，连接机构包括 长杆和短杆，长杆和短杆构成转动连接，短杆的一端固定有小球P’，小球设置在竖直面10’上。当长杆以O’为转轴在平面10’内逆时针转动时，在忽略重力与离心力的条件下：小球P’在A点受到短杆的拉力T以及与平面10’之间的摩擦力f，在两者合力作用下相对于长杆沿着图中箭头所示方向运动，直到小球P’运动至相对平衡位置B点，此时小球P’受到方向相反大小相等的短杆的拉力T’和静摩擦力f’，因此相对于长杆不再继续运动，此时短杆位于以点O’为圆心的小球P’所在的圆周的切线上。反之，当长杆以O’为转轴在平面10’内逆时针转动时，小球P’相对于长杆从C点运动至相对平衡位置B点。
根据以上原理模型，可以理解的，本实施例中的离合件15相当于小球P’和短杆构成的整体，主动件152相当于长杆，其中，驱动部151c与壳体154之间形成的摩擦相当于小球P’与竖直面10’构成的摩擦。
如图10至图15所示，传动装置15还包括止挡部155，止挡部155设置在活动部151b的运动轨迹内的某一个断开位置，即不与从动件153构成连接或接触的任意位置，用于在驱动部151c运动至平衡位置之前阻止活动部151b相对主动件152继续运动，从而使得驱动部151c也停止相对于主动件152的运动。由于主动件152的尺寸限制，因此本实施例中设置了止挡部155限制活动部151b的运动范围，避免活动部151b与其他部件发生干涉。也即是说，由于从动件153和止挡部155的限位，活动部151b只能在驱动位置和止挡部155所在位置对应的断开位置之间运动，从而限定了驱动部151c也只能在与这两个位置对应的位置之间运动。本实施例中，当活动部151b与从动件153啮合时活动部151b的位置为活动部151b的驱动位置，对应离合件151的第一位置；当活动部151b与从动件153分离时活动部151b的位置为活动部151b的断开位置，活动部151b的断开位置有多个，活动部151b只要不与从动件153啮合均处于断开位置，分别对应离合件151的多个第二位置。而当活动部151b运动至与止挡部155发生作用的位置时，其所对应的位置为活动部151b相对于主动件152可到达的最远的断开位置。在一些实施例中，止挡部155为设置在主动件152表面的限位销，当然止挡部155也可以采用其他限位结构。图10至图13所示为活动部151b和驱动部151c在两个极限位置的示意图，其中图10、图11中活动部151b处于驱动位置，驱动部151c处于与活动部151b的驱动位置相对应的位置，图12、图13中活动部151b处于断开位置且抵触至止挡部155，驱动部151c处于与活动部151b的该断开位置相对应的位置。
离合件151可以为一个由金属材质制成的离合件，可以是一体成型或者由多部分组装而成。主动件152为齿轮，驱动部151c和活动部151b分别沿主动件152的厚度方向安装至主动件152的两侧，驱动部151c始终与主动件152的表面相接触。连接部151a为连接轴，沿主动件152的厚度方向穿过主动件152， 与主动件152构成转动连接，连接轴的轴向长度约等于齿轮的厚度。活动部151b和驱动部151c分别固定连接至连接部151a的两端或者与连接部151a一体成型，三者构成同步运动。
驱动部151c为一个金属弹片，驱动部151c可以为勺形金属弹片，勺形金属弹片具有一个向外突出的凸面151d，凸面151d与壳体154的接触面154a构成挤压接触从而形成产生摩擦力的垂直于接触面154a的压力，在驱动部151c相对主动件152运动的过程中，凸面151d与壳体154的接触面154a发生滑动摩擦；作为一种可选择的实施方式，驱动部151c包括能够与壳体154构成磁性连接的磁性元件，通过磁吸力形成产生摩擦力的垂直于接触面154a的压力，此时，壳体154可以本身由磁性材料制成也可以在接触面154a安装有磁性元件。当然，可以理解的，驱动部151c与壳体154接触的结构，只要能够实现驱动部151c与壳体154的相对滑动即可。
活动部151b可以为金属棘爪，从动件153可以为棘轮，活动部151b位于驱动位置时，棘爪与棘轮配合，棘轮与轮子13相连，马达14驱动轮子13转动的过程中，马达轴141驱动主动件152转动，棘爪推动棘轮转动，棘轮驱动轮子13转动，从而实现整个传动装置15的运转。活动部151b和驱动部151c均沿垂直于连接部151a的轴线的方向延伸，且两者的延伸方式大致垂直。
在一些实施例中，轮子13与棘轮构成同轴固定连接。可以理解的，活动部151b和从动件153的结构也可以是除棘轮棘爪之外的其他配合结构，只要能够实现马达14正转时，活动部151b在驱动位置驱动从动件153转动即可。
另外，如图2至图4所示，传动装置15还包括减速装置156，可以为减速齿轮箱，减速装置156设置于容纳主动件152和从动件153的壳体154的外部，马达14经过减速装置156减速后再传递动力至主动件152，在一些实施例中，减速装置156包括三级减速。
如图16至图18所示，与第一实施例中的手推式自驱行进机器100的离合件151一致，本申请的第二实施例的手推式自驱行进机器的离合件251也具有第一位置和第二位置，且离合件251在第一位置和第二位置之间切换，在离合件251位于第一位置时，离合件251允许主动件252将动力传输至从动件253，在离合件251位于第二位置时，离合件251断开马达和轮子之间的动力的传递路径；另外，本实施例中离合件251在第一位置和第二位置之间的切换也是通过电机的正反转实现的。不同的是，本实施例中离合件251可转动地安装至从动件253，在离合件251运动至第一位置时，离合件251与主动件252接触，在离合件251运动至第二位置时，离合件251与主动件252脱离。另外，本实施例中的主动件252由齿轮和棘轮构成同轴固定连接或者一体成型而成，在一些实施例中，主动件252由直齿轮和棘轮构成同轴固定连接或者一体成型而成， 本实施例中的从动件253的结构，只要是能够与轮子配接并能驱动轮子转动即可。
同样地，离合件251包括驱动部251c，连接部251a和活动部251b，连接部251a可转动地安装至主动件252或从动件253，活动部251b和驱动部251c分别连接至连接部251a或者与连接部251a一体成型。所述活动部251b具有断开位置和驱动位置，驱动部251c能够驱动活动部251b在断开位置和驱动位置之间切换；当活动部251b处于驱动位置时，马达轴能够驱动轮子转动，当活动部251b处于断开位置时，轮子能相对于马达轴自由转动。本实施例中的离合件251与第一实施例中的离合件251的结构排布不同且驱动部251c驱动活动部251b相对主动件252发生的运动的原理也不同。本实施例中的离合件251的连接部251a可转动地安装至从动件253，驱动部251c与活动部251b位于从动件253沿其厚度方向的同一侧。驱动部251c与主动件252的靠近驱动部251c的表面构成接触。在一些实施例中，从动件253沿其厚度方向开有连接孔253a，连接部251a配接至连接孔253a，驱动部251c与主动件252的棘轮的外表面构成接触且形成有垂直于该接触面252a的正压力。本实施例中的驱动部251c为一个金属弹片，与主动件252之间构成挤压接触从而形成产生摩擦的垂直于接触面252a的压力；作为一种可选择的实施方式，驱动部251c可以包括能够与主动件252构成磁性连接的磁性元件，通过磁吸力形成产生摩擦的垂直于接触面252a的压力，此时，主动件252可以本身由磁性材料制成也可以在接触面252a安装有磁性元件。
需要说明的是，本实施例中离合件251在第一位置与第二位置之间切换的运动原理与第一实施例中的离合件251不同。由于本实施例中的离合件251安装至从动件253，当马达驱动主动件252转动时，连接至从动件253的连接部251a并不跟随主动件252一起转动，仅仅是接触至主动件252的驱动部251c受到滑动摩擦力相对于主动件252发生位移，从而带动活动部251b相对于主动件252发生位移。在一些实施例中，当主动件252被马达驱动沿方向201’转动，驱动部251c在滑动摩擦力的作用下向前运动，从而带动活动部251b向下运动直到与棘轮啮合实现啮合驱动。反之，当主动件252被马达驱动沿与方向201’相反的方向转动，驱动部251c在滑动摩擦力的作用下向后运动，从而带动活动部251b向上运动实现离合断开。当然，主动件252上也可以设置有止挡部对活动部251b进行限位，第一实施例中可以适用于本实施例中的内容均能够应用到本实施例中，在此不作过多介绍。
