机壳110的一端为与电池包113结合的电池包结合部115，另一端包裹着切割部210。在电池包结合部115和切割部210之间，机壳110包裹着电路板114、马达111和齿轮箱116，并且向切割部210延伸形成供操作者握持的握持部220。机壳110形成的容纳空间1100，容纳空间1100容纳有马达111、齿轮箱116、含电路板114的控制系统、输出轴117、第一驱动组件120、转动组件130和第二驱动组件400(见图11)。
握持部220处还设置有开关112，开关112用于控制马达111的启停。开关112附近设置有拨钮1121，通过拨动拨钮来调节马达111的旋转方向。需要注意的是，管道切割机100也可以市电为能量来源。在本实施例中，马达111是一种电机。需要说明的是，切割部210至少包括切割片143。
如图2所示，切割部210的右侧的齿轮组件为第一驱动组件120，第一驱动组件120被机壳110包裹。输出轴117从齿轮箱116伸出，延伸至切割部210。输出轴117的旋转激活第一驱动组件120，从而驱动转动组件130转动。
如图3和图4所示，被切割的管道104被放置在转动组件130的切割片143、第 一滚轮151和第二滚轮152围成的区域中，且转动组件130基本绕被切割管道104被卡紧在切割部210时的中心轴线旋转。当转动组件130旋转时，切割片143绕管道104的外侧表面切割，最终将其切穿。在切割作业中，第一滚轮151和第二滚轮152在被切割的管道104上滚动，以防止被切割的管道104被过度摩擦。
如图4所示，第一驱动组件120包括第一安装板128，第一安装板128上安装有第一齿轮121、第二齿轮122和第三齿轮123，输出轴117的旋转驱动第一齿轮121旋转，然后经第二齿轮122和第三齿轮123，将旋转运动传递至第四齿轮124。第四齿轮124通过螺钉127与转动组件130固定。当第四齿轮124转动时，转动组件130与第四齿轮124同步转动。
在本实施方式中，第一齿轮121的转动由驱动块125驱动。图5A至图5C示出了驱动块125可能出现的不同转动位置。通过设置驱动块125，使得第一齿轮121的旋转可滞后于驱动块125的转动。驱动块125可在第一齿轮121内部旋转。第一齿轮121上具有一个凸台1211，当驱动块125的凸起部未接触第一齿轮121上的凸台1211时，驱动块125不驱动第一齿轮121旋转，此时驱动块125处于空行程。
以图5A至图5C为例，若图5A中的驱动块125为初始状态，当驱动块125以第一方向R1旋转至图5B中的驱动块125b时，驱动块125的凸出部始终未接触凸台1211，在此过程中第一齿轮121未被驱动块的旋转而驱动。当图5B中的驱动块125b继续以第一方向R1运动至图5C的驱动块125时，驱动块125的凸出部开始与凸台1211接触，从而驱动第一齿轮121转动。第一齿轮121、第二齿轮122和第三齿轮123的端部由卡圈126固定。
如图6和图7所示，转动组件130包括第一壳体131和第二壳体132，第一壳体131位于第二壳体132的右侧。由于第一壳体131与第四齿轮124固定，当第一驱动组件120驱动第四齿轮124转动时，转动组件130与第四齿轮124同步转动。
如图8至图10所示，转动组件130的第一壳体131和第二壳体132形成的容纳空间容纳有托架组件和上锁组件160。在一种实施例中，托架组件包括第一托架组件140、第二托架组件150。第一托架组件140位于第二托架组件150的上方，上锁组件160将第一托架组件140和第二托架组件150连接。通过给上锁组件160“上锁”，使第一托架组件140和第二托架组件150共同将管道104夹紧，从而避免管道104在切割过程中被松开。第一托架组件140与第二托架组件150形成切割区域105(见图3)，被切割管道104放置在切割区域105内，转动组件130可驱动切割片143对管道104进行旋转切割。可以理解的是，图3示出的切割区域105只 是一个大致的示意区域，表示第一托架组件140与第二托架组件150能切割的区域的最大范围。
为使第一托架组件140与第二托架组件150之间弹性件被设置能相互靠近，以夹紧管道104。如图8所示，第二托架组件150包括第一弹性件153，第一弹性件153能使第二托架组件150向第一托架组件140靠近。在本实施例中，第一弹性件153为一种弹簧。在将管道104装入切割部210时，管道104向下挤压第二托架组件150，第一弹性件153被压缩。当管道104装入第一托架组件140与第二托架组件150之间后，在第一弹性件153的作用下，第二托架组件150向第一托架组件140靠近，以夹紧管道104。为了保证第二托架组件150移动的稳定性以及防止第二托架组件150向第一托架组件140移动过度，还设置了第二弹性件165。第一弹性件153的一端与转动组件130抵接，另一端与第二托架组件150抵接。第二弹性件165的一端与转动组件130抵接，另一端与第一托架组件140抵接。第二弹性件165套设于锁定板164上。
如图9和图10所示，第一托架组件140包括第一支撑架141和第二支撑架142和安装于两个支撑架之间的切割片143。上锁组件160包括摇臂161、顶杆162、锁定块163和锁定板164。锁定板164的一侧为锯齿状，当锁定板164的延伸方向与锁定块163的延伸方向基本垂直时，锁定块163内的开口使锁定板164可以上下运动。锁定块163被顶杆162顶至倾斜时能卡在锁定板164上的锯齿上，使第二托架组件150相对于第一托架组件140固定，实现第二托架组件150的锁定。
如图9所示，摇臂161a位于放松位置，锁定板164的延伸方向与锁定块163的延伸方向基本垂直。当摇臂161a被拨动至如图10所示的锁紧位置时，摇臂161b将顶杆162的底面顶起，顶杆162又进一步将锁定块163a顶至163b，使得锁定板164的延伸方向与锁定块163的延伸方向呈小于90度的夹角。在此状态下，锁定块163和锁定板164相互锁死，锁定块163无法再向上运动，第二托架150与第一托架140相对静止。
需要说明的是，锁定板164可以与第一托架组件140或第二托架组件150连接，或者与第一托架组件140或第二托架组件150一体成型。
如图11所示，管道切割机100的切割部210可进一步被拆分为上文描述过的第一驱动组件120、转动组件130，以及下文即将描述的输出轴组件300和第二驱动组件400。其中，输出轴组件300驱动位于第二驱动组件400旋转，进而驱动转动组件130上的摇臂161转动，进而实现上锁组件160的上锁加压。第一驱动组件 120和第二驱动组件400分别设置在转动组件130的两侧。
图12和图13揭示了输出轴组件300的具体实施方式。输出轴组件300容纳在壳体结构中。在本实施例中，输出轴117以第一直线301方向延伸，第一驱动轴312以第二直线302方向延伸，第二驱动轴321以第三直线303方向延伸。第一直线301基本垂直于第二直线302和第三直线303，且第二直线302与第三直线303基本平行。第一驱动轴312驱动第一驱动组件120运动，第二驱动轴321驱动第二驱动组件400运动。
输出轴组件300由第一组件310、第二组件320和第三组件330构成。第一组件310由第一驱动轴312、第六齿轮311和第七齿轮313装配而成，第二组件320由第二驱动轴321和第八齿轮323装配而成，第三组件330由输出轴117和第五齿轮119装配而成。输出轴117的一端连接有第五齿轮119，该第五齿轮119与第六齿轮311相啮合，从而驱动与第一驱动轴312配合的驱动块125转动，驱动块125再驱动第一齿轮121转动。第七齿轮313随第一驱动轴312转动，从而驱动第八齿轮323转动。第一轴承118设置在输出轴117的末端，第二轴承314设置在第二齿轮311的外侧。第二组件320又可被称作跳档组件或离合组件，其具体结构见图14至图16。
图15和图16分别为第二组件320在两种视角下的爆炸图，图15省略了第三弹性件324和位于第二驱动轴321两端的两个轴承。
如图15所示，第二驱动轴321的一侧为具有扁位的第一端部3211，该第一端部3211与第二驱动组件400外侧的第九齿轮401(见图11)相连。第二驱动轴321的另一侧为具有扁位的第二端部3212，第二端部3212驱动转动件322转动。如图16所示，转动件322的一侧为凹凸的表面。在本实施方式中，转动件322包括凸起的凸起面3221，位于相邻两个凸起面3221之间的是凹下的下凹面3222，相邻的凸起面3221和下凹面3222由过渡面3223连接。如图15所示，第八齿轮323与转动件322相配合的一侧也为与转动件322类似的凹凸结构，在此不在赘述。第三弹性件324设置在止挡部3211和转动件322之间，使得转动件322第一凹凸面3220与第八齿轮323的第二凹凸面3230基本吻合，以传递扭矩。
图17至图19揭示了第二驱动组件400的具体结构。第二安装板420的一侧装有齿圈410，另一侧装有第一推动组件430和第二推动组件440。在本实施例中，第一推动组件430包括第一推动件431，第一推动件431的第一连接件432穿过齿圈410上的第一孔位412，实现紧固。在本实施例中，第一连接件432和第一孔位 412的个数为两个。在其他实施例中，第一连接件432和/或第一孔位412也可以为多个。当齿圈410转动时，第一推动件431随齿圈410同步转动。
如图17所示，第二安装板420上具有第一轨道421和第二轨道422，第一推动组件430沿第一轨道421运动，第二推动组件440沿第二轨道422运动。
如图19所示，第二推动组件440包括第二推动件441和第三推动件442。第二推动件441和第三推动件442通过第二连接件443连接，使得第三推动件442可绕第二连接件443的第二轴线445旋转。第二推动件441通过第三连接件446与齿圈410相连，使得第二推动件441可随齿圈410同步转动。在本实施例中，第三连接件446的个数为2。因此，当齿圈410转动时，第一推动件431和第二推动件441随齿圈410同步转动。第二推动组件440还包括第一扭簧447和第二扭簧444。
图20为图11中的结构装配起来的立体图。结合图11、图20和图21，立柱423设置在第一安装板128和第二安装板420之间。一方面，立柱423用于在装配过程中使安装人员可以快速将第二安装板420进行准确的定位；另一方，立柱423限定了第三推动件442的旋转角度。下面结合图22至图27进行进一步的详细描述。
现在描述管道切割机100的锁紧过程。
图22至图27揭示了通过第二驱动组件400的变化驱动转动组件130进行上锁加压的过程。其中，图22和图23示出了齿圈410相对于第二安装板420可移动至的第一位置和第二位置，图24和图25为当齿圈410按照图22和图23分别移动至第一位置和第二位置时，摇臂161被推动到的位置示意图，图26和图27分别为图24和图25的左视图。
结合图11至图16所示的输出轴组件300，此时马达111从静止开始启动，驱动输出轴117沿第二方向R2(见图11)旋转，齿圈410开始以第三方向R3(见图22)旋转，齿圈410的旋转驱动第一推动件431旋转，进而驱动摇臂161的外端向上移动，实现锁紧功能。如图22至图25所示，从未锁紧到锁紧的过程中，齿圈410从图22所示的第一位置旋转到图23所示的第二位置，摇臂161从图24所示的解锁位置被拨动到图25所示的锁紧位置。
需要说明的是，在不受到额外推力作用时，第二推动组件440中的第二推动件441和第三推动件442处于如图24所示的状态。也就是说，在自然状态下(如图26所示)，第三推动件442受到扭簧的力，使其与第二推动件441之间的夹角近似于直角。然而，结合图21、图25和图27所示，当第一推动件431随齿圈410旋转时，第二推动件441也随齿圈410旋转，第三推动件442在上移过程中遇到立柱 423，使得第三推动件442被立柱423“挡住”，而不会高出切割部210的机壳顶端。在此情况下，第二推动件441和第三推动件442之间的夹角逐渐变大。具体来说，如图26所示，第二推动件441以第一延伸线4411的方向延伸，第三推动件442以第二延伸线4421的方向延伸。在从图26到图27所示的位置，第一延伸线4411和第二延伸线4421之间的夹角变大，也就是第二推动件441和第三推动件442之间的夹角变大。当第二推动件441随齿圈旋转，使得第三推动件442逐渐离开立柱423时，第二推动件441和第三推动件442之间的夹角又逐渐减小，回归至自然状态。
结合图4至图5C，在摇臂161从解锁位置(图24)被拨动到锁紧位置(图25)的过程中，驱动块125从图5A中的位置以第一方向R1旋转至图5B中的位置，在此空行程中，第一齿轮121未被马达111驱动旋转。随着马达111的继续在转动，驱动块125从图5B中的位置继续以第一方向R1旋转至图5C中的位置，从而驱动第一齿轮121开始转动。
在摇臂161从图24所示的解锁位置被拨动到图25所示的锁紧位置时，受到第一轨道421或第二轨道422(见图17)的限制，无法继续再相对于转动组件130旋转。但此时马达111依然在绕第二方向R2转动，第二组件320被激活，齿圈410保持在图23所示的锁紧位置，第二组件320重复离合跳档的动作。
下面描述管道切割机100的解锁过程。
在切割过程结束后，转动组件130停止时，转动组件130的开口1324(见图24)可能朝向任意方向，并且摇臂161可能停止在多种位置。
如图28和图29所示，作为一种可能的情况，摇臂161的停止位置处在第二驱动组件400以第六方向R6(见图23)运动时的运动路径上。这样，在解锁过程中，齿圈410从第二位置(如图23)运动至第一位置(如图22)，第一推动组件430和第二推动组件440推动摇臂161运动至图29所示的位置，实现解锁。然后，齿圈410受到第一轨道421或第二轨道422(见图17)的限制，无法继续沿第六方向R6(见图23)旋转，此时离合组件(即第二组件320)被激活。
在解锁过程中，马达111驱动输出轴117沿与第二方向R2相反的第四方向R4旋转，也可称为反转。如图5C所示，马达111反转时，驱动块125以与第一方向R1相反的第五方向R5旋转。在驱动块125从图5C中的位置旋转至图5A中的位置的过程中，驱动块125处于空行程，第一齿轮121未被驱动转动。如图23所示，齿圈410从第二位置，以与第三方向R3相反的第六方向R6旋转，运动至如图22所示 的第一位置。
图27至图31示出了摇臂161从锁紧位置被拨动至解锁位置的侧视图。如图28所示，第三推动件442逐渐远离立柱423，且第二推动件441的一侧抵住摇臂161的外圆周1611(见图8)，并推动摇臂161旋转。如图29所示，第三推动件442彻底离开立柱423，第三推动件442恢复至其自然状态，并下压摇臂161，使上锁组件160被解锁。
作为另一种可能的情况，摇臂161停止在图30所示的停止位置，在此情况下，第二驱动组件400以第六方向R6运动至第一轨道421的边界。当第二驱动组件400运动至停止时，到达如图22所示的位置，但无法经过摇臂161的停止位置，也就无法触发摇臂161运动。第二组件320重复跳档动作，转动组件130以第七方向R7旋转(如图31)。摇臂161的外圆周1611接触并推动第二推动件441，从而实现解锁。
如图32和图33所示，在切割作业完成、管道104还被锁紧在切割部210内时，操作者通过操作开关112和拨钮1121，改变马达111的旋转方向。在管道切割机100进行解锁之前，操作者已放开控制单马达111启停的开关112，转动组件130停止转动，此时转动组件130的开口1324可能朝向任何方位停止。如图34所示，开口1324可能朝上，使得管道104也无法被拿出。因此，在第二壳体132上设置有一个止转部1321，止转部1321的作用在于限定转动组件130转动停止时的位置，使转动组件130的开口1324与机壳110的开口1101对齐。
结合图7、图32和图33所示，止转部1321设置有止转面1322和斜面1323。见图35，止挡件450设置在机壳110的限位槽内，因此止挡件450位置固定。当转动组件130以第三方向R3(见图22)转动时，第二壳体132受到止挡件450的阻挡，只能旋转至图32所示的位置，在此位置处，转动组件130的开口1324与机壳110的开口1101对齐。当转动组件130以第六方向R6(见图23)转动时，止挡件450的止挡头451从第二壳体132上的斜面1323上滑过。所以当马达111正转时，止挡件450并不会阻止转动组件130的转动。
图32揭示了一种止挡件450的实施方式，即止挡件450a；图33揭示了另一种止挡件450的实施方式，即止挡件450b。止挡件450包括弹簧，使得止挡头451可以沿弹簧的轴向移动。
需要说明的是，在本申请揭示的实施方式中，马达111既可以驱动第一驱动组件120，也可以驱动第二驱动组件400。在一些实施方式中，第一驱动组件120 和第二驱动组件400可以以不同的动力源来驱动。比如，第一驱动组件120以马达111驱动，二驱动组件400以不同于马达111的第二马达驱动。在一些实施方式中，二驱动组件400的第一推动组件430和/或第二推动组件440可由手动调节驱动的方式实现位置的变化。在一些实施方式中，也可以使用螺线圈来调节第二驱动组件400的位置。
结合图3所示，输出轴117的一端连接切割部210，另一端连接动力部215。也可以说，输出轴117的一端连接驱动切割片143旋转的转动组件300，另一端连接齿轮箱116内的齿轮减速机构。握持部220为由机壳110包裹输出轴117及开关112而形成的部位。
在本实施例中，握持部220位于切割部210和电池包结合部115之间，握持部220位于切割部210和齿轮箱116之间，握持部220位于切割部210和马达111之间。输出轴117为一根长轴，输出轴117在介于齿轮箱116与第一轴承118之间的第一距离L大于或等于80mm且小于或等于115mm。
如图36所示，当管道切割机100安装有电池包113时，管道切割机100的整机重心G位于握持部220的握持区域221上。本申请揭示的管道切割机100呈“哑铃”状，前侧的切割部210和后侧的动力部215像哑铃的重量集中的两端，握持部220设置在切割部210和动力部215之间，有利于操作者在握持管道切割机100时获得较好的握持体验，不易因整机的前部过重而给操作者的手腕带来过度负荷，整机更易掌控。
握持部220的后端的第一线101的外周长大于或等于100mm且小于或等于140mm，第一线101在开关112所在的区域外。第二线102大致位于开关112的中心，因此，第二线102的外周长包括了开关112需要被手指按压的部分，第二线102的外周长大于或等于140mm且小于或等于175mm。握持部220的中端的第三线103的外周长大于或等于115mm且小于或等于145mm，第三线103在前后方向上位于第一线101和第二线102的中点处。
图37为图36中沿A-A方向的截面图，截面壳体的长径为L1，短径为L2。第四线104为握持部220上不包括开关112的部分的最前端，在一种实施方式中，当A-A截面位于第一线101和第四线104之间时，长径L1大于或等于35mm且小于或等于47mm，短径L2大于或等于25mm且小于或等于37mm。因此，本申请揭示的结构使得握持部220的外周长较小，握持部220在上下方向和左右方向上较细，方便操作者握持。
需要说明的是，管道切割机100的整机重心G位于握持部220的握持区域221上，是指当操作者的手指按压开关112时，按压开关112的手握持管道切割机100时所占的区域。也就是说，若操作者用与按压开关112不同的手去握持管道切割机100的其他位置，如马达111外部的壳体区域、或电池包113所处的位置，并不属于本申请揭示的握持区域221的范围。若电池包结合部115与按压开关112的握持区域部分重叠，则落在本申请揭示的范围内。
管道切割机100的电池包113的标称电压大于或等于10.8V且小于或等于36V，标称电压为电池包113的产品说明书或外包装上显示的电压值。表一示出了当电池包113的标称电压为24V时的电流测试数据，表二示出了当电池包113的标称电压为24V时的功率计算数据。
表一
表二
在表一中，管道直径指被切割的铜管的公称直径，其单位为英寸。此处的公称直径并非管道的外径，管道的外径比公称直径大1/8英寸。切割时长指将铜管彻底切断所需的总时间，其单位为秒。启动最大瞬时电流为马达初启时能达到的最大电流，该最大电流为一瞬时值。将切断一根管道的切割时长三等分，前1/3平均电流指在切割时长的最前1/3的时间内，管道切割机100的电流的平均 值；中1/3平均电流指在切割时长的中间1/3的时间内，管道切割机100的电流的平均值；后1/3平均电流指在切割时长的最后1/3的时间内，管道切割机100的电流的平均值。
表二中的参数含义与表一类似，在此不再赘述。表二中的功率值由表一中的电流值乘以电池包113的标称电压24V而得到。由表二可得，在切割五种不管径的管道104时，管道切割机100的全程平均功率由102.5W增加至159.2W。本申请揭示的管道切割机100的平均功率大于或等于100W。
下面描述管道切割机100在锁紧过程中涉及的控制方法。
管道切割机100可以配置有控制组件，控制组件能够检测握持部220的开关112是否开启、以及检测拨扭1121被拨动后所指示的马达111的旋转方向。
在上文描述的管道切割机100的锁紧过程中，随着用户拨动拨扭1121为正转方向并开启握持部的开关112，控制组件可以控制马达111正转，齿圈410相对第二安装板420将由图22所示的第一位置旋转至图23所示的第二位置，同时，摇臂161的外端受第一推动件431驱动，也将由图24所示的解锁位置上抬至图25所示的锁紧位置，进而实现锁紧功能；由于驱动块125需要与凸台1211接触后方能驱动第一齿轮121转动以带动转动组件130，在锁紧完成前，驱动块125处于空行程，直至齿圈410受第一轨道421和/或第二轨道422的限制而停止、第二组件320重复离合跳档的动作后，转动组件130方能驱动切割片143正转以对管道104进行旋转切割。
下面描述管道切割机100在解锁过程中涉及的控制方法。
在上文描述的管道切割机100的解锁过程中，随着用户拨动拨扭1121为反转方向并开启握持部的开关112，控制组件可以控制马达111反转，齿圈410相对第二安装板420将由图23所示的第二位置旋转至图22所示的第一位置；由于驱动块125需要与凸台1211接触后方能驱动第一齿轮121转动以带动转动组件130，直至齿圈410受第一轨道421和/或第二轨道422的限制而停止、第二组件320重复离合跳档的动作后，转动组件130方能反转，与转动组件130一同转动的摇臂161的外端受第二推动件441驱动，也将由图25所示的锁紧位置下压至图24所示的解锁位置，进而实现解锁功能；此外，转动组件130将在受到止挡件450的阻挡后停止转动。
下面描述管道切割机100在关停过程中涉及的控制方法。
管道切割机100还可以配置有参数检测组件，其中，参数检测组件可以包括 位置传感器，位置传感器能够对转动组件130等进行诸如角度等位置参数的测量并将测得的位置参数传输至控制组件。一个实施例中，位置传感器为霍尔传感器，霍尔传感器被装配在诸如第一安装板128等位置固定的组件上，同时，在转动组件130上装配磁铁以供霍尔传感器感应测量转动组件130当前所在的位置。
在上文描述的管道切割机100的锁紧过程中，拨钮1121拨为正转方向，随着用户关闭开关112，控制组件可以控制马达111继续正转，同时，基于参数检测组件所传输的位置参数检测转动组件130是否处于第一目标位置，继而在转动组件130处于第一目标位置或用户关闭开关112已达第一预设时长的情况下，控制马达111停机。一个实施例中，第一目标位置为转动组件130的开口方向与第一安装板128、第二安装板420的开口方向错开并呈第一预设角的位置，第一预设角可以为90°，即，转动组件130处于开口方向与第一安装板128、第二安装板420开口方向相垂直的位置，从而在本机解锁前避免管道104脱离管道切割机100的意外危险。
在上文描述的管道切割机100的解锁过程中，拨钮1121拨为反转方向，随着用户关闭开关112，作为一种实施方式，由于反转转动组件130受到止挡件450的阻挡后已经停止在第二目标位置，控制组件可以控制马达111停机。一个实施例中，第二目标位置为转动组件130的开口方向与第一安装板128、第二安装板420的开口方向对应一致的位置，以使本机解锁后用户能够方便地从管道切割机100中取出已切割的管道104。
作为另一实施方式，如不采用止挡件450阻挡方式使转动组件130停驻，也可由控制组件控制马达111继续反转，同时，基于参数检测组件所传输的位置参数检测转动组件130是否处于第二目标位置，继而在转动组件130处于第二目标位置或用户关闭开关112已达第一预设时长的情况下，控制马达111停机。
下面描述管道切割机100在自保护过程中涉及的控制方法。
管道切割机100所配置的参数检测组件还能够对上文描述过的电池包113等进行诸如电压、电流、温度等参数的检测，并将测得的参数传输至控制组件，控制组件可以基于参数检测组件所传输的参数对管道切割机进行欠压保护、过流保护、过温保护中的一或多项。
作为一种实施方式，控制组件可以检测电池包113的电压参数是否为第一目标压值，并在是的情况下，控制马达111停机。
作为另一实施方式，控制组件可以检测电池包113的电压参数是否为第一目 标电压值，并在是的情况下，进一步确定马达111当前所处的状态，继而针对马达111当前所处的状态对马达111执行对应操作。一个实施例中，在检测到电池包113电压为2.5V/Cell且马达111处于运转状态的情况下，控制马达111停机。另一实施例中，在检测到电池包113电压为2.5V/Cell且马达111处于待启动正转状态的情况下，控制马达111停机，而在检测到电池包113电压为2.5V/Cell且马达111处于待启动反转状态的情况下，控制马达111反转预设次数或反转第二预设时长后，控制马达111停机。
以上显示和描述了本申请的基本原理、主要特征和优点。本行业的技术人员应该了解，上述实施例不以任何形式限制本申请，凡采用等同替换或等效变换的方式所获得的技术方案，均落在本申请的保护范围内。
