【具体实施方式】
下面将结合本申请实施例中的附图,对本申请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申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域技术人员在没有付出创造性劳动前提下所获得的所有其他实施例,都属于本申请的保护范围。
本申请实施例提供了一种电机,请参阅图1和图2,图1为本申请实施例提供的电机的结构示意图,图2为图1所示的电机的截面示意图。电机100包括壳体110、第一驱动模组120、第二驱动模组130、联动组件140、第一输出轴150和第二输出轴160。
壳体110可以形成电机100的整体框架并作为其他部件的承载体。
第一驱动模组120设置于壳体110内。示例性地,第一驱动模组120可以为第一定子转子模组,第一定子转子模组内部可以包括第一转子、磁铁、第一定子等,转子可以相对定子转动,定子可以包括磁钢片和线圈等。第二驱动模组130设置于壳体110内,且与第一驱动模组120间隔设置。示例性地,第二驱动模组130可以为第二定子转子模组,第二定子转子模组内部可以包括转子、磁铁、定子等,转子可以相对定子转动,定子可以包括 磁钢片和线圈等。第二定子转子模组可以和第一定子转子模组为相同的结构(具体包括第二转子、磁铁、第二定子等,关于这部分的详细结构在本领域技术人员的理解范围内,此处不再赘述),在一些其他实施例中,第一驱动模组120和第二驱动模组130也可以为不同的结构,此处不作具体限定。
联动组件140设置于壳体110内,联动组件140与第一驱动模组120和第二驱动模组130连接。联动组件140可以根据需要包括不同数量和不同类型的齿轮。联动组件140与第一输出轴150连接并可以驱动第一输出轴150转动,联动组件140与第二输出轴160连接并可以驱动第二输出轴160转动。
其中,第一驱动模组120和第二驱动模组130通过联动组件140驱动第一输出轴150和第二输出轴160转动,且第一输出轴150和第二输出轴160的转速分别可调。例如,可以根据需要设置第一输出轴150的转速为第一转速,第二输出轴160的转速为第二转速,第一转速和第二转速均可以根据需要调整,如此,可以通过一个电机100得到两个转速可以可调的两个输出轴,相当于两个只有单输出轴的电机100。另外,通过同一个联动组件140驱动第一输出轴150和第二输出轴160,电机100的集成度高,相比与两个只有单输出轴的电机100方案,具有两个输出轴的电机100占用的空间更少,重量更轻。
为了方便理解,假设第一驱动模组120的输入转速为n1,第二驱动模组130的输入转速为n2,第一输出轴150的输出转速为n3,第二输出轴160的输出转速为n4,则其对应输入输出关系式为:
n3=k1*n1+k2*n2;
n4=k3*n1+k4*n2;
其中,k1、k2、k3、k4为四个固定的系数,四个系数根据联动组件140中对应齿轮的参数确定。例如,四个系数可以由联动组件140中对应齿轮的齿轮模数、齿数、齿轮中心距、齿轮变位系数等值综合确定。可以理解的是,驱动第一输出轴150转动的为联动组件140中的第一部分齿轮,驱动第二输出轴160转动的为联动组件140的第二部分齿轮,第一部分齿轮和第二部分齿轮至少部分不同,进而导致系数k1和系数k3不同,系数k2和系数k4不同。
需要说明的是,转速n3和转速n4可以互不影响,也可以不成比例关系,可以任意调整,方向也可以相同,也可以相反,数值也可以任意配置,只需通过计算出的耦合转速公式分配转速n3和转速n4即可。因此,第一输出轴150的转动方向能够在与第二输出轴160的转动方向同向和反向之间切换。例如,第一输出轴150的转动方向为顺时针,第二输出轴160的转动方向可以为顺时针也可以根据需要切换为逆时针。
另外,根据功率=扭矩×转速,本申请实施例中的电机,其单个输出轴其获得的输出功率,是可大于单个驱动模组的输出的。其中,最极端情况,两个驱动模组的输出功率,可以均集中在其中一个输出轴上,比如在一个输出轴不转(或者转动,但输出扭矩为零),另一个输出轴转(或者不转,输出转速为零)的时候,相当于两个驱动模组的功率(通过联动组件140对转速和扭矩进行调配)均输出到了一个转动的输出轴上。总之,两个驱动模 组的功率(包括转速和扭矩)能够分配,便于形成合力,输出的功率(扭矩和转速在两个输出轴之间的分配)更加灵活。通过选择合适的转速和转矩方向,可以实现把两个电机的功率都分配到一个输出轴上进行输出,以大于单个驱动模组的输出。
请结合图3和图4,图3为图1所示电机中联动组件的结构示意图,图4为图3所示联动组件的爆炸图。联动组件140可以包括中心轴140a(作为联动组件140的一个输入端)和齿轮组140b,第一驱动模组120与中心轴140a连接,且能够驱动中心轴140a转动。中心轴140a通过齿轮组140b驱动第一输出轴150转动,第二驱动模组130与齿轮组140b连接,并通过齿轮组140b驱动第二输出轴160转动。
中心轴140a可以穿设于第一驱动模组120,第一驱动模组120可以驱动中心轴140a转动,中心轴140a驱动联动组件140中的齿轮转动,以实现第一输出轴150转动。第一驱动模组120的转子内表面与中心轴140a固定连接。例如,中心轴140a与转子内表面设有的周向凸起和凹槽结构定位压紧,以实现固定连接。第二驱动模组130可以驱动齿轮组140b中一个齿轮转动,该齿轮再带动其他齿轮转动,以实现第二输出轴160转动。
联动组件140的结构可以根据需要设置。示例性地,中心轴140a(也即第一驱动齿轮的连接轴)的端部具有齿部140a1(也即第一驱动齿轮);齿轮组140b(齿轮模组)可以包括第一齿轮141(也即第二驱动齿轮,也即联动组件140的一个输入端)、多个第二齿轮142、多个第三齿轮143、齿圈144和后行星架145。第一齿轮141套设于中心轴140a并可相对于中心轴140a转动。多个第二齿轮142围绕第一齿轮141设置且均与第一齿轮141啮合。多个第三齿轮143围绕中心轴140a设置且与中心轴140a的齿部140a1啮合,多个第三齿轮143还与多个第二齿轮142一一对应啮合。多个第二齿轮142均设置于齿圈144内且与齿圈144啮合,齿圈144与第一输出轴150固定连接。后行星架145套设于中心轴140a,后行星架145与第二输出轴160固定连接,后行星架145上设有多个第一安装部1452和多个第二安装部1454,多个第一安装部1452与多个第二齿轮142一一对应安装,多个第二安装部1454与多个第三齿轮143一一对应安装。
中心轴140a的齿部可以带动第三齿轮143转动,第三齿轮143带动第二齿轮142转动,第二齿轮142带动齿圈144转动,齿圈144带动第一输出轴150转动;第二驱动模组130驱动第一齿轮141转动,第一齿轮141带动第二齿轮142转动,第二齿轮142在齿圈144内转动,第二齿轮142带动后行星架145转动,后行星架145带动第二输出轴160转动,其中,第一齿轮141、第二齿轮142、齿圈144和后行星架145形成齿轮模组。
通过联动组件140可以配合第一驱动模组120和第二驱动模组130驱动第一输出轴150和第二输出轴160转动,并且第一输出轴150和第二输出轴160的转速可以根据需要调整。联动组件140的多个齿轮都设置在齿圈144内,联动组件140结构紧凑,集成度高,体积小,从而使电机100的整体体积也小。其中,本实施例中的第一输出轴150和第二输出轴160均为环状结构且第一输出轴150和第二输出轴160的轴心重合。
可选的,联动组件140还可以包括第一轴承146、第二轴承147和第三轴承148。第一轴承146设置于中心轴140a和第一齿轮141之间,以使第一齿轮141通过第一轴承146围 绕中心轴140a转动。第二轴承147设置于第二齿轮142和第一安装部1452之间,以使第二齿轮142可通过第二轴承147围绕第一安装部1452转动。第三轴承148设置于第三齿轮143和第二安装部1454之间,以使第三齿轮143可通过第三轴承148围绕第二安装部1454转动。通过第一轴承146、第二轴承147和第三轴承148,第一齿轮141可以更好的围绕中心轴140a转动,第二齿轮142可以更好的围绕第一安装部1452转动,第三齿轮143可以更好的围绕第二安装部1454转动。
其中,中心轴140a可以为中空结构,中心轴140a具有中空腔,电机100还包括连接线,连接线穿设于中空腔,第一驱动模组120和第二驱动模组130通过连接线连接外部电路。利用中心轴140a中间的中空腔布设连接线,即方便连接线的设置,中心轴140a可以很好的保护连接线,而且连接线又不容易外露而导致卷绕。
中心轴140a的中空腔内的连接线也可以用于连接第一外部电路和第二外部电路。例如,第一外部电路可以为控制电机的控制电路,第二外部电路可以为用于检测的传感器,控制电路通过穿设于中心轴140a内的连接线与传感器连接,中心轴140a可以很好的保护连接线,而且连接线又不容易外露和卷绕。
第一输出轴150和第二输出轴160设置于壳体110的同一侧。两个输出轴都在最外端且在同一侧,方便外接转动件,同时降低负载惯量,减少功耗。
为了方便更好地了解本实施例的电机,下面对电机的整体结构进行详细说明。请结合图5,图5为图1所示电机的爆炸图。本实施例的电机100还可以包括第一主板170和第二主板180第一输出轴承150a、第二输出轴承160a。壳体110包括后壳112、主壳114和前端盖116,后壳112和前端盖116设置于主壳114的两侧,主壳114、后壳112和前端盖116构成了电机100的主体结构,并用于承载其他结构。第一驱动模组120和第二驱动模组130均安装于主壳114,第一主板170、第二主板180设置于主壳114内且对应第一驱动模组120和第二驱动模组130设置。例如,第一驱动模组120为中空结构,第一主板170设置于第一驱动模组120的中空结构内,第二驱动模组130为中空结构,第二主板180设置于第二驱动模组130的中空结构内,且与第一主板170相邻设置,第一轴承146设置于主壳114内,中心轴140a穿设于第一驱动模组120、第二驱动模组130、第一主板170、第二主板180和第一轴承146。电机100还可以包括第四轴承120a和第五轴承130a,第四轴承120a设置在主壳114和第一驱动模组120之间,第五轴承130a设置在主壳114和后行星架145之间。
为了更好的理解本实施例的电机100,下面详细说明电机100的装配过程:
首先,以主壳114为承载基体,主壳114为中空结构,将第一驱动模组120装入主壳114并将其与主壳114进行定位,再将第一主板170、第二主板180装配进入主壳114的内腔体内。
其次,将第二驱动模组130装入主壳114,同样将其与主壳114进行定位;其中,第一主板170设置于第一驱动模组120的中空区域内,第二主板180设置于第二驱动模组130的中空区域内。
第三,先将中心轴140a、第一轴承146、第一齿轮141预装配,如将第一齿轮141通过第一轴承146安装于中心轴140a;再将此装配好后模组装配进主壳114内,并将中心轴140a远离第一齿轮141的一端穿过第二驱动模组130、第一驱动模组120、第一主板170和第二主板180,并且将中心轴140a与第一驱动模组120的转子上的周向凸起、凹槽结构定位压紧。
第四,先将3个第二齿轮142与3个第二轴承147、3个第三齿轮143与3个第三轴承148一一对应装配起来,然后将后行星架145装配进入主壳114并套设在中心轴140a之后,将3套第二齿轮142与第二轴承147、3套第三齿轮143与第三轴承148分别装配于后行星架145上。其中,中心轴140a端面的齿与3个第三齿轮143啮合,3个第三齿轮143分别与3个第二齿轮142相互啮合,第一齿轮141与3个齿轮第二啮合。
第五,将第二输出轴160装配进入,并利用螺丝将第二输出轴160与后行星架145锁紧。
第六,先将齿圈144与第一输出轴150配合装配,如通过螺丝锁紧,再将齿圈144与3个第二齿轮142啮合装入。
第七,装配第一输出轴承150a和第二输出轴承160a,以使第一输出轴150通过第一输出轴承150a与主壳114连接,第二输出轴160通过第二输出轴承160a与第一输出轴150的内圈连接。
第八,在主壳114靠近第一输出轴一侧装入前端盖116,并将前端盖116与主壳114锁紧;在主壳114远离第一输出轴一侧装入后壳112,并将后壳112和主壳114锁紧。
本申请实施例还提供一种电子设备,电子设备包括电机,电机为上述任意一个实施例的电机,在此不再赘述。具体的,请一并参阅图1和图6,图6为本申请实施例提供的电子设备的结构示意图。电子设备10可以包括运动机构200,运动机构200可以包括相互连接的第一运动肢体220和第二运动肢体240,电机100设置于运动机构200内,并能够驱动第一运动肢体220和第二运动肢体240。具体的,请结合图1至图5,电机100的第一输出轴150可以驱动第一运动肢体220运动,电机100的第二输出轴160驱动第二运动肢体240运动。
为了更好的理解电子设备10,下面以电子设备10可以为机器人为例进行说明。运动机构200可以为腿部,第一运动肢体220可以为大腿,第二运动肢体240为小腿,第一输出轴150驱动大腿运动,第二输出轴160驱动小腿运动。另外,在一些其他实施例中,运动机构还可以是机器人的手臂等其他具有关联运动的机械结构,譬如第一运动肢体可以是机器人的大臂,而第二运动肢体则可以是机器人的小臂等,关于运动机构的更多应用场景,在本领域技术人员的理解范围内,此处不再一一列举并详述。
相关技术的机器人中,腿部可以包括大腿和小腿两部分。大腿和小腿需要两个外转子直流无刷电机提供动力,驱动大腿运动的大腿电机在大腿内侧,驱动小腿运动的小腿电机通过法兰盘连接在大腿电机输出端,小腿电机输出端通过四连杆或皮带传动至小腿端,驱动小腿旋转。因为大腿和小腿的运动分别由各自的电机驱动,正常走路或跑步状态下,需 要分别控制对应的电机做一定的运动,功耗较大;小腿电机、大腿模块、小腿组件均成为大腿电机的负载,大腿电机的负载惯量大;大腿和小腿两个电机,导致整机重量、体积和厚度都比较大。
相比于两个电机分别驱动大腿和小腿的机器人,本实施例的电机100具有两个输出轴,可以分别控制大腿和小腿,集成度高,使整机的重量、体积和厚度都较小。在正常走路或跑步状态下,电机100内部双驱动模组同时承载,共同分担大小腿的功耗,相比于两个电机分别控制大腿和小腿,功耗更低,功率分配更合理。电机100的两个输出轴均在最外端且位于同一侧,电机100的负载仅包括大腿及小腿模块,负载惯量降低,也可以降低运动时的功耗。驱动大腿和小腿的电机集成后,相比于两个电机分别控制大腿和小腿,减少了大腿电机至小腿电机的走线,避免了在待改进的两个电机组合的方案中,线束经过另一电机导致卷绕的问题,提高了连接的可靠性、稳定性。
示例性地,假设第一输出轴150外部连接的是大腿端,第二输出轴160外端通过四连杆机构连接至小腿端。当需要小腿不动,只旋转大腿时,其运动形式如下:小腿不动,即需要第二输出轴160和后行星架145保持不转动,需要第二齿轮142和第三齿轮143不公转,只需要自传,此时,由第一驱动模组120提供动力,第一驱动模组120驱动中心轴140a转动,假设为顺时针转动,此时,第三齿轮143以对应的速度逆时针转动,第二齿轮142以对应的速度顺时针转动,此时将运动传递至齿圈144,齿圈144以对应的速度顺时针转动,驱动第一输出轴150也同样保持同样的速度顺时针转动,从而驱动大腿转动。
另一示例中,为了保持后行星架145转动,同步地,需要第一齿轮141保持一定的速度逆时针旋转,即需要第二驱动模组130提供对应的速度值。当第二驱动模组130的转动速度值小于此值时,小腿顺时针进行转动,当第二驱动模组130的转动速度值大于此值时,小腿逆时针进行转动。此例仅为其一种运动形式,在机器人走路或跑步状态下,一般都是两个驱动模组共同作用,协同作用驱动第一输出轴150、第二输出轴160以对应的速度进行旋转,且输出速度与两个驱动模组的转子的转速都成确定的关系值。
本申请实施例中的电机,可以将两个驱动模组的功率(扭矩和转速)协调地输入到一个新型齿轮减速器(本申请实施例中的联动组件),该齿轮减速器具有两个输入端和两个输出端,并在输入和输出端之间,由齿轮机构本身形成一定的速比关系,即雅克比矩阵。通过设计齿轮减速器的传动关系,可以使两个电机的功率在两个关节之间动态分配,并且峰值力矩/功率可以大于单个电机,以此来实现降低电机功率选型的目的。
需要说明的是,本实施例的电机还可以应用于手臂,如第一输出轴驱动上臂,第二输出轴驱动下臂。
本实施例的电子设备可以为需要两个输出轴控制的设备。例如,电子设备可以为移动终端,移动设备具有内置的摄像头,电机的第一输出轴可以驱动摄像头在移动终端内部和外部之间移动,电机的第二输出轴可以驱动摄像头在移动终端外部旋转。
其中,电机100还包括第一霍尔传感器(未示出)和第二霍尔传感器182,第一霍尔传感器用于检测第一驱动模组120的第一磁通量,第二霍尔传感器182用于检测第二驱动模 组130的第二磁通量。例如,第一驱动模组120的转子上可以设置第一磁片122,第二驱动模组130的转子可以设置第二磁片132,第一霍尔传感器设置在第一主板170上,第二霍尔传感器182设置在第二主板180上,第一磁片122跟随第一驱动模组120的转子转动,第一霍尔传感器可以检测第一磁片122的磁通量变化,从而得到第一磁通量。第二磁片132跟随第二驱动模组130的转子转动,第二霍尔传感器182可以检测第二磁片132的磁通量变化,从而得到第二磁通量。
电子设备10还包括处理器300,处理器300与第一霍尔传感器和第二霍尔传感器182连接以得到第一磁通量和第二磁通量,并根据第一磁通量用于得到第一驱动模组120的转子的第一转动值,以及根据第二磁通量用于得到第二驱动模组130的转子的第二转动值。
当第一转动值与第一目标转动值的第一差值大于第一差值阈值时,处理器300根据第一转动值调节第一驱动模组120,以使调节后的第一驱动模组120的转动值与第一目标转动值的差值小于第一差值。
当第二转动值与第二目标转动值的第二差值大于第二差值阈值时,处理器300根据第二转动值调节第二驱动模组130,以使调节后的第二驱动模组130的转动值与第二目标转动值的差值小于第二差值。
处理器300得到第一转动值和第二转动值后可以检测第一驱动模组120和第二驱动模组130是否按照预设转动值转动,若没有则可以调整输出以使第一驱动模组120和第二驱动模组130的转子的转动值达到或接近预设转动值,即通过第一霍尔传感器和第二霍尔传感器182测试得到的第一磁通量和第二磁通量实现反馈控制。
在上述实施例中,对各个实施例的描述都各有侧重,某个实施例中没有详述的部分,可以参见其他实施例的相关描述。
在本申请的描述中,术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示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一个或者更多个特征。
