下面结合附图具体描述根据本公开实施例的滑差收卷轴100。
如图1至图6所示，根据本公开实施例的滑差收卷轴100包括：驱动轴10、多个磁性件20和多个差速齿轮组件30。
具体而言，驱动轴10绕其自身的轴线可转动，多个磁性件20沿驱动轴10的轴向间隔开设于驱动轴10，每个差速齿轮组件30分别与对应的磁性件20相配合的设于驱动轴10，每个磁性件20分别与驱动轴10同步活动，以驱动对应的差速齿轮组件30绕驱动轴10的轴线转动，其中，相邻两个差速齿轮组件30中的至少一个，相对于对应的磁性件20沿驱动轴10的轴向在第一位置和第二位置之间可活动，在差速齿轮组件30处于第一位置的情况下，相邻两个磁性件20上的差速齿轮组件30彼此间隔开，在差速齿轮组件30处于第二位置的情况下，相邻两个磁性件20上的差速齿轮组件30彼此连接且同步运动。
换言之，根据本公开实施例的滑差收卷轴100主要由驱动轴10、多个 磁性件20和多个差速齿轮组件30构成。其中，滑差收卷轴100可以用于驱动收卷臂，对隔膜进行分切。
为了便于说明，可以定义驱动轴10的轴线方向为第一方向，驱动轴10可以绕自身的轴线转动。可选地，驱动轴10可以由驱动件驱动，在驱动件的驱动下绕自身轴线转动，驱动件包括但不限于电机。需要说明的是，通过调整驱动轴10的转速，可以达到不同的扭矩传递需求。
在驱动轴10的外周面上可以设有多个磁性件20，且多个磁性件20可以沿第一方向间隔开，每个磁性件20可以与驱动轴10同步绕驱动轴10的轴线转动。
在驱动轴10的外周侧还设有多个差速齿轮组件30，每个差速齿轮组件30可以与至少一个磁性件20相对应，当磁性件20在驱动轴10的驱动下进行转动时，磁性件20可以通过磁场驱动差速齿轮组件30绕驱动轴10的轴线转动。需要说明的是，差速齿轮组件30与磁性件20之间可以相对转动，磁性件20可以对差速齿轮组件30实现异步驱动。
另外，为了便于说明，可以定义驱动轴10上任意相邻两个差速齿轮组件30分别为第一差速组件和第二差速组件，对应的磁性件20分别为第一磁性件和第二磁性件。第一差速组件可以与第一磁性件相对，第二差速组件可以与第二磁性件相对。
其中，第一差速组件可以相对于第一磁性件沿第一方向活动，和/或第二差速组件可以相对于第二磁性件沿第一方向活动，以实现第一差速组件和/或第二差速组件在第一位置和第二位置之间切换。第一位置可以是第一差速组件和第二差速组件相远离的位置，第二位置可以是第一差速组件和第二差速组件相靠近的位置。
下面以第一差速组件可以在第一位置和第二位置之间可活动，第二差速组件保持固定为例对相邻的两个差速齿轮组件30之间的配合进行详细说明。
当第一差速组件处于第一位置时，第一差速组件可以与第二差速组件间隔开，此时，两个差速齿轮组件30可以独立转动。每个差速齿轮组件30可以分别驱动一个收卷臂，具有张力控制稳定，精度高的优点。
当第一差速组件处于第二位置时，第一差速组件可以与第二差速组件连接并构成一个整体，此时，两个差速齿轮组件30可以同步活动。构成整体的两个差速齿轮组件30可以驱动一个收卷臂，由于两个差速齿轮组件30受到对应的第一磁性件和第二磁性件驱动，因此，通过连接两个滑差齿轮组件可以实现收卷臂张力的翻倍，以便于适应不同收卷宽度对应的不同张力需求，提高滑差收卷轴100的适用性。
另外，在第一差速组件保持固定，第二差速组件在第一位置和第二位置之间可活动，或第一差速组件和第二差速组件均可在第一位置和第二位置之间可活动的情况下，也可以通过对应的差速齿轮组件30的活动，切换相邻两个差速齿轮组件30之间的连接状态，使得相邻两个差速齿轮组件30断开或连接，以实现两个差速齿轮组件30相对独立驱动对应的两个收卷臂或两个差速齿轮组件30构成整体后驱动一个收卷臂。
此外，还可以通过相邻的多个差速齿轮组件30在第一方向上的活动，使得三个或三个以上的差速齿轮组件30连接并构成一个整体，驱动一个收卷臂，以进一步提高张力，满足不同的张力需求。
由此，通过本公开实施例提供的滑差收卷轴100，在驱动轴10上设置磁性件20驱动对应的差速齿轮组件30，利用相邻差速齿轮组件30中的至少一个沿驱动轴10的轴向可活动，可以实现相邻差速齿轮组件30之间的断开或连接，使得相邻差速齿轮32既可以相对独立转动，独立驱动对应的收卷臂，也可以连接形成一个整体，共同驱动一个收卷臂，实现张力提升，以满足不同收卷宽度对应的不同张力需求，提高滑差收卷轴100的适用性。
根据本公开的一个实施例，每个差速齿轮组件30分别包括导磁转子31和差速齿轮32。具体地，导磁转子31绕驱动轴10的轴线可转动地设于驱动轴10，导磁转子31与对应的磁性件20配合以由磁性件20驱动，差速齿轮32设于导磁转子31且与导磁转子31同步转动。
换句话说，本实施例的差速齿轮组件30可以主要由导磁转子31和差速齿轮32构成。其中，导磁转子31可以与驱动轴10同轴设置，并可以绕驱动轴10的轴线转动，另外，导磁转子31还可以相对于磁性件20转动，也就是说，导磁转子31可以相对于驱动轴10转动。
具体地，导磁转子31可以具有磁性，磁性件20可以是套设在驱动轴10上的永磁转子，永磁转子的外周或端面可以镶嵌有与导磁转子31配合的永磁体，且永磁转子上的永磁体的NS极交错布置。
在驱动轴10驱动磁性件20转动时，导磁转子31可以和磁性件20产生相对转动，导磁转子31可以切割磁性件20的磁力线，从而产生感应涡流，感应涡流的磁场与磁性件20的磁场之间可以产生推动导磁转子31转动的作用力，使得导磁转子31绕驱动轴10的轴线转动。需要说明的是，导磁转子31和磁性件20的转动的方向相同。
另外，差速齿轮32可以套设在导磁转子31上，并与导磁转子31固定连接，在导磁转子31转动时，差速齿轮32可以与导磁转子31同步转动，实现驱动轴10到差速齿轮32之间的扭矩传递。差速齿轮32可以与收卷臂连接，以驱动收卷臂工作。
可选地，导磁转子31的内周侧可以设有用于容纳永磁转子的容置腔312，且永磁转子和容置腔312的槽壁之间具有间隙，以便于永磁转子和导磁转子31进行相对运动。
在本实施例中，将差速齿轮组件30设置为包括导磁转子31和差速齿轮32，可以利用导磁转子31与磁性件20的配合，通过磁场驱动导磁转子31转动，实现导磁转子31与驱动轴10之间的差速转动。另外，在导磁转子31上设置与导磁转子31同步转动的差速齿轮32，方便通过差速齿轮32与收卷臂连接，驱动收卷臂工作，实现扭矩的传递。
根据本公开的其他一些实施例，差速齿轮32相对于导磁转子31在第一位置和第二位置之间可活动。
具体地，在第一方向上，每个差速齿轮组件30中的差速齿轮32可以相对于导磁转子31在第一位置和第二位置之间活动。
当差速齿轮32处于第一位置时，差速齿轮32可以与相邻的差速齿轮32之间间隔开，以使得相邻的两个差速齿轮组件30独立转动。
当差速齿轮32处于第二位置时，差速齿轮32可以与相邻的差速齿轮32固定连接，从而使得相邻两个差速齿轮组件30连接构成一个整体进行同步转动，实现张力翻倍。
在本实施例中，通过设置差速齿轮32相对于导磁转子31在第一位置和第二位置之间活动，可以连接或断开相邻两个差速齿轮32，以实现相邻两个差速齿轮组件30的连接或断开，操作简单，可靠性高。
在本公开的一些具体实施方式中，导磁转子31的外周面设有沿驱动轴10的轴向延伸的滑槽311，差速齿轮组件30还包括锁紧件，锁紧件与差速齿轮32连接，且锁紧件的一部分穿过差速齿轮32伸入滑槽311，锁紧件沿滑槽311的延伸方向可活动。
具体而言，滑槽311可以设置在导磁转子31外周面，且滑槽311可以沿第一方向延伸，差速齿轮32的内壁面可以与导磁转子31的外周面相对，滑槽311的开口可以朝向差速齿轮32的内壁面。
差速齿轮32上可以连接有锁紧件，锁紧件的一部分可以穿过差速齿轮32的内壁面伸入滑槽311中，并与滑槽311的槽底面相对。锁紧件在锁紧位置和解锁位置之间可活动。
在锁紧件处于锁紧位置时，锁紧件可以将差速齿轮32和导磁转子31锁紧，使差速齿轮32和导磁转子31固定连接并同步转动。
在锁紧件处于解锁位置时，锁紧件可以解除差速齿轮32和导磁转子31之间的锁定，使差速齿轮32可以相对于导磁转子31在第一位置和第二位置之间活动，且在差速齿轮32相对于导磁转子31活动时，锁紧件伸入滑槽311的一部分可以沿滑槽311的延伸方向活动，即沿第一方向活动，以引导差速齿轮32沿第一方向活动。
在本实施例中，利用差速齿轮32上设置的锁紧件与导磁转子31外周面的滑槽311配合，可以引导差速齿轮32沿驱动轴10的轴线方向活动，提高差速齿轮32活动的稳定性，避免差速齿轮32在活动过程中发生偏移或抖动而影响相邻两个差速齿轮32之间的连接。另外，通过设置锁紧件还可以锁紧或解锁差速齿轮32，在实现差速齿轮32与导磁转子31同步活动的同时，还便于在需要调整张力时移动差速齿轮32。
根据本公开的一些可选实施例，锁紧件为沿差速齿轮32的径向可活动的锁紧螺钉33，在锁紧件的一端止抵滑槽311的内壁面时，差速齿轮32与导磁转子31固定连接，在锁紧件的一端脱离滑槽311的内壁面时，差速 齿轮32相对于导磁转子31可活动。
具体地，本实施例中的锁紧件可以为锁紧螺钉33，差速齿轮32上可以设有沿自身的径向延伸的螺纹孔，锁紧螺钉33可以与螺纹孔连接，通过旋转锁紧螺钉33可以使锁紧螺钉33在差速齿轮32的径向上活动。锁紧螺钉33的一端可以穿过差速齿轮32的内壁面伸入滑槽311中。
当锁紧螺钉33的一端与滑槽311的内壁面止抵时，锁紧螺钉33可以处于锁紧位置，将差速齿轮32和导磁转子31锁紧在一起，实现差速齿轮32与导磁转子31的固定连接，使得差速齿轮32与导磁转子31同步转动。
当锁紧螺钉33的一端与滑槽311的内壁面脱离，即锁紧螺钉33与滑槽311的内壁面间隔开时，锁紧螺钉33可以处于解锁位置，使得差速齿轮32可以相对于导磁转子31在第一位置和第二位置之间活动。
在本实施例中，将锁紧件设置为锁紧螺钉33，通过锁紧螺钉33在差速齿轮32的径向上活动可以对差速齿轮32和导磁转子31进行锁定或解锁，具有结构简单，易于操作的优点。
根据本公开的其他一些实施例，相邻两个差速齿轮32的一个差速齿轮32设有第一配合部，相邻两个差速齿轮32的另一个差速齿轮32设有第二配合部，在差速齿轮32位于第一位置时，第一配合部与第二配合部脱离，在差速齿轮32位于第二位置时，第一配合部与第二配合部连接。
具体而言，第一差速组件可以包括第一差速齿轮，第一差速齿轮上可以设有第一配合部，第二差速组件可以包括第二差速齿轮，第二差速齿轮上可以设有第二配合部，第一配合部和第二配合部可以相对设置。
当差速齿轮32位于第一位置时，第一配合部和第二配合部之间可以间隔可以使得两个配合部之间脱离，从而使得两个差速齿轮32可以独立被对应的导磁转子31驱动。
当差速齿轮32位于第二位置时，第一配合部和第二配合部可以配合连接，从而将两个差速齿轮32之间可以固定连接，使得两个差速齿轮32的同步活动，实现张力的翻倍。
可选地，第一配合部和第二配合部之间的配合包括但不限于卡扣配合、卡槽配合。
在本实施例中，通过在相邻差速齿轮32上分别设置第一配合部和第二配合部，通过差速齿轮32在第一位置和第二位置之间的活动以及两个配合部之间的配合，可以实现相邻两个差速齿轮32之间的连接或断开，方便根据不同的收卷宽度改变差速齿轮32的位置，以改变差速齿轮32提供的张力。
可选的，每个差速齿轮32上可以分别设有第一配合部和第二配合部，且第一配合部可以设置在差速齿轮32的一端，第二配合部可以设置在差速齿轮32的另一端，以使得差速齿轮32可以和任意一端所对应的相邻的差速齿轮32通过第一配合部和第二配合部连接。

当差速齿轮32位于第一位置时，凸起部321可以与凹部322分离，即凸起部321可以与凹部322的开口间隔开，以使得两个差速齿轮32可以独立转动。
当差速齿轮32位于第二位置时，凸起部321可以插入凹部322中，使得两个差速齿轮32连接并同步转动。
在本实施例中，将第一配合部设置为凸起部321，将第二配合部设置为与凸起部321相对的凹部322，通过凸起部321与凹部322的配合，可以实现相邻两个差速齿轮32的连接或断开，具有结构简单，可靠性高的优点。
