本发明的实施方式
下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能解释为对本发明的限制。
如图1至图6所示，电子成像设备M包括主组件170、托盘171和门盖11，主组件170中设置有容纳部、鼓驱动传递单元203、分离机构以及转印单元等，托盘171可容纳处理盒100，并能够相对主组件170移动以将处理盒100安装至主组件170的容纳部内。门盖11设置在主组件170的外侧，其能够打开或关闭主组件170的容纳部。
如图1所示，主组件170内设有四个处理盒100(100Y、100M、100C、100K)，即第一处理盒100Y、第二处理盒100M、第三处理盒100C和第四处理盒100K。四个处理盒100基本水平地布置。旋转驱动力分别从主组件170的驱动输出部分，主组件170向第一至第四处理盒100(100Y、100M、100C、100K)分别提供偏置电压(充电偏压、显影偏压等)。处理盒100是通过一个托盘171安装到主组件170内的。具体是托盘171构造成能够在主组件170安装于水平表面上的状态下沿着大致水平的方向移动，四个处理盒100分别安装到托盘171的每个定位部。当托盘171移动到主组件170中，多个处理盒100一并随托盘171移动到主组件170内。当处理盒100需要更换时候，多个处理盒100可以一起随托盘171移动到主组件170外部。
处理盒100具有显影联接部件(显影驱动力接收部分)和鼓联接部件(感光部件联接部件)。关闭主组件170的门盖11，用于将驱动力传递到处理盒的主组件侧鼓驱动传递单元203和显影驱动传递单元接合以将驱动传递到处理盒。
当打开门盖11的过程中，鼓驱动传递单元203、显影驱动传递单元缩回且脱离处理盒100的鼓联接部件和显影联接部件，进而托盘171和处理盒100可顺利从主组件170中取出。
如图2以及图4所示，设置在主组件170上的鼓驱动传递单元203包括驱动力传递组件和制动力施加组件，其中驱动力传递组件包括旋转构件201和鼓驱动件180，旋转构件201可旋转地支撑在支撑轴202上，鼓驱动件180的一端设置有用于接收驱动力的旋转止动部分180b，另一端设置有驱动力传递部180d，驱动力传递部180d为沿圆周方向分布在鼓驱动件180内壁的凸起部，鼓驱动件180的中轴位置还设有定位部180i。
鼓驱动件180以可沿轴向M1可移动的方式装配在旋转构件201上，通过设置在旋转构件201的旋转止动部分201b和设置在鼓驱动件180的旋转止动部分180b之间的配合，实现旋转构件201带动鼓驱动件180的旋转。
如图2至图6所示，制动力施加组件包括制动构件206、第一移动部件204、第二移动部件208、第一接合弹簧211、第二接合弹簧210以及制动传递构件207，其中制动构件206包括固定侧206a和旋转侧206b，固定侧206a与支撑轴202固定连接，旋转侧206b能够相对于固定侧206a旋转并产生制动力，产生制动力的方法可以从使用摩擦和粘度的那些方法中适当地选择。
第一移动部件204和第二移动部件208用于向处理盒100施加制动力，二者可通过旋转止动突起部208c和旋转止动凹部204c卡合的方式组装在一起，二者可以具有同步的动作过程。第二移动部件208位于第一移动部件204的内侧，第一移动部件204的接合部分204b能够与驱动力传递部180d贴合或相互抵靠。
制动传递构件207的轴部分207b穿过第一移动部件204和第二移动 部件208的中部的通孔并连接至制动构件206的旋转侧206b，以能够向第一移动部件204和第二移动部件208传递制动力。
具体的，制动传递构件207的凸缘部分207a设置有突起部207e，对应的在第一移动部件204的凸缘部分204a设置有突起部204e，当制动传递构件207的突起部207e与第一移动部件204的突起部204e接合时，制动传递构件207可向第一移动部件204传递制动力。
第一移动部件204和第二移动部件208能够相对制动传递构件207和制动构件206在第一预设轴线M1上移动，当制动传递构件207的突起部207e与第一移动部件204的突起部204e在第一预设轴线M1上错开或分离时，第二移动部件208和第一移动部件204将不接收制动力。
继续的，参考图4和图5，第一接合弹簧211的一端抵压在制动构件206的端面206d，另一端抵压在第一移动部件204的凸缘部分204a上，第一接合弹簧211处于被压缩的状态，其沿M1B方向向第一移动部件204施加弹性力，该弹性力可使得制动传递构件207的突起部207e保持与第一移动部件204的突起部204e接合。
第二接合弹簧210是压缩螺旋弹簧，并且被设置成夹在并压缩在制动构件206的端面206d和制动传递构件207的凸缘部分207a之间，第二接合弹簧210将排斥力(推压力、弹力)施加到制动构件206的端面206d和制动传递构件207的凸缘部分207a中的每一者。
在上述鼓驱动传递单元203的各部件中，在第一接合弹簧211和第二接合弹簧210的作用下，制动传递构件207在轴向方向M1A上的端部处的突起部207f抵靠鼓驱动件180的接触表面108f。鼓驱动件180在箭头M1B方向上的运动被轴向方向限制部分212管制(限制)，使得鼓驱动件180不会从主组件170侧的鼓驱动传递单元203脱落。
在上述鼓驱动传递单元203的各部件中，鼓驱动件180是能够相对于旋转构件201在M1A和M1B方向上移动的，第一移动部件204和第二移动部件208能够相对于制动传递构件207和旋转构件201在M1A和M1B方向上移动，也能够相对于鼓驱动件180在M1A和M1B方向上移动。
如图2至图6所示，现有技术中，当鼓驱动件180转动而处理盒未与 鼓驱动件180配合时，也即鼓驱动件180空转时，鼓驱动件180在M1A方向一侧的凸起部挤压制动传递构件207在M1B方向一侧的凸起部，两者的凸起部均为斜面，使得制动传递构件207朝向鼓驱动件180内部移动(沿M1A方向移动)，且制动传递构件207带动第一移动部件204、第二移动部件208也朝向鼓驱动件180内部移动，当鼓驱动件180转动至其凸起部经过制动传递构件207的凸起部后，制动传递构件207、第一移动部件204、第二移动部件208在第一接合弹簧211、第二接合弹簧210的作用力下回弹(向M1B方向移动)并产生异响；当鼓驱动件180转动至驱动力传递部180d上的驱动传递面180d1与第一移动部件204接触时，带动第一移动部件204转动，而制动传递构件207不转动，当第一移动部件204转动至其上面的突起部204e与制动传递构件207的突起部207e接触时，第一移动部件204朝着鼓驱动件180内部的方向移动，当第一移动部件204的突起部204e经过制动传递构件207的突起部207e后，第一移动部件204回弹产生异响。
鼓驱动件180内设有装配槽213，装配槽213于鼓驱动件180的表面形成敞口，敞口面向联轴器106的位置设置，装配槽213的延伸方向与第一方向D1相平行，当处理盒100安装至图像形成装置内以后，鼓驱动件180沿第一方向D1朝向联轴器106移动，联轴器106可自敞口延伸进装配槽213内，驱动力传递部180d形成于装配槽213内。
驱动力传递部180d包括凸设于装配槽213内壁面上的块体结构，本实施例中，块体结构设有两个，两个块体结构对称设置于定位部180i的中心线的相对两侧。
实施例一
参照图7至图14所示，本发明提供了一种处理盒300，用于安装至图像形成装置内。
处理盒100，包括显影单元103、鼓单元104以及驱动组件。
显影单元103包括显影框架130、显影辊、显影联轴器132、显影辊齿轮、送粉辊、送粉辊齿轮和出粉刀。鼓单元104包括鼓框架131、感光鼓105、联轴器106和充电辊。
显影框架130围成存储碳粉的粉仓，显影框架130大致为长条盒子形状，显影框架130在长度方向的两端分别设有驱动侧轴承和导电侧轴承，送粉辊、显影辊可旋转的支撑在显影框架130长度方向两端的驱动侧轴承和导电侧轴承上，送粉辊、显影辊可在驱动组件的作用下旋转，送粉辊和显影辊的轴向均沿显影框架130的长度方向。送粉辊将碳粉输送到显影辊且被带电的显影辊吸附。
鼓框架131也具有长度方向，其长度方向与显影框架130的长度方向一致，鼓框架131长度方向的两端分别设置有驱动侧端盖102和导电侧端盖101，感光鼓105可旋转的支撑在鼓框架131在长度方向上的两端，具体是支撑在驱动侧端盖102和导电侧端盖101上，感光鼓105轴向的两端分别设置驱动轴承和导电轴承，感光鼓105通过驱动轴承和导电轴承分别支撑在驱动侧端盖102和导电侧端盖101的通孔上。感光鼓105设置在鼓框架131在高度方向上的下端侧。显影单元103和鼓单元104通过驱动侧端盖102和导电侧端盖101彼此联接。显影辊和感光鼓105相互靠近，显影辊吸附的碳粉通过与感光鼓105之间的电势差将碳粉转移给感光鼓105，充电辊用于对感光鼓105表面充上均匀电荷，从而使感光鼓105能够吸附碳粉。
显影联轴器132、显影辊齿轮、送粉辊齿轮、搅拌架齿轮设置于驱动侧轴承的外侧，具体的，驱动侧轴承上设有用于支撑显影联轴器132的支撑孔，显影联轴器132用于与电子成像设备的显影驱动传递单元啮合并接收驱动力；显影辊齿轮套设在显影辊的轴伸出于驱动侧轴承的一端，送粉辊齿轮套设在送粉辊的轴伸出于驱动侧轴承的一端，显影辊齿轮、送粉辊齿轮直接或间接与显影联轴器132啮合，以将显影联轴器132接收到的驱动力传递，从而带动显影辊、送粉辊旋转。
联轴器106设置在感光鼓105在长度方向(轴向)的端部，联轴器106用于接收电子成像设备的驱动力(通过与鼓驱动件180接合传递)从而带动感光鼓105旋转。
参照图9所示，本实施例中的联轴器106的第一端连接于感光鼓105的轴端，联轴器106的第一端设置有凹陷(图中未示出)可以与感光鼓 105起到卡合作用或者是二者在安装时起到安装方位识别点的作用。联轴器106的第二端设有分离部107以及接合部108，分离部107与接合部108沿预设旋转方向A依次分布。
分离部107包括凸设于联轴器106第二端的环状凸起结构，接合部108凹陷形成于环状凸起结构端面的凹槽结构，接合部108的位置与尺寸与驱动力传递部180d的位置与尺寸相对应。
本实施例中，参照图4以及图10所示，装配槽213内设有定位部180i，联轴器106上设有定位配合部109，定位配合部109用于与定位部180i之间形成定位配合，一种可行的实施方式中，定位部180i为凸设于驱动力传递部180d上的定位凸柱，定位凸柱的轴线与驱动力传递部180d的轴线相重合，定位凸柱朝向装配槽213的敞口方向延伸，定位配合部109为凸设于联轴器106第二端的定位凸环，定位凸环的内环面与定位凸柱的外周面相间隙配合，优选地，定位凸环的内环面可以设置圆锥形倒角，使得在定位凸柱与定位凸环相接合的过程中起到引导的作用。
分离部107的厚度沿第一方向D1不均匀设置，有利于分离部107与活动件之间产生摩擦力或过盈力，使得鼓单元104与图像形成装置安装更牢固，打印过程中接合更稳定。
如图11-14对联轴器106与鼓驱动件180的接合过程做详细描述。联轴器106与鼓驱动件180的初始姿势(初始的相对位置)有2种，分为第一种姿态和第二种姿态。第一种姿态指联轴器106上设置的接合部108位于驱动力传递部180d上设置的驱动力传递部180d对应位置的沿旋转方向A的上游侧，需要经过鼓驱动件180沿A方向旋转一定距离，达到第二种姿态，即接合部108位于驱动力传递部180d相对应的正上方，接合部108与驱动力传递部180d可直接接合。
本实施例的工作过程为：
鼓驱动件180处于第一姿态时，当处理盒100需要安装到图像形成装置上时，处理盒100安装到托盘上，然后，处理盒100与托盘一起推入图像形成装置内，关闭前门，鼓驱动件180沿第一方向D1伸出与鼓单元104上的联轴器106相接合。当鼓驱动件180沿第一方向D1伸出过程中，联 轴器106上设置的分离部107插入活动件(第一移动部件204与第二移动部件208)之间。由于此时联轴器106上设置的接合部108位于鼓驱动件180上设置的驱动力传递部180d对应位置的沿预设旋转方向A的上游侧，即接合部108与驱动力传递部180d并未对应接合，此时分离部107下端面与驱动力传递部180d上端面抵接，此时鼓驱动件180与联轴器106可以相对运动。
而后，鼓驱动件180在电机驱动下，开始沿预设旋转方向A旋转，由于联轴器106上设置的接合部108位于鼓驱动件180上设置的驱动力传递部180d对应位置的沿预设旋转方向A的上游侧，且鼓驱动件180与联轴器106可以相对运动，因此在经过鼓驱动件180沿预设旋转方向A旋转一定距离后，鼓驱动件180到达第二姿态，即接合部108位于驱动力传递部180d相对应的位置。此时鼓驱动件180沿第一方向D1移动伸出一定距离，接合部108与驱动力传递部180d卡接，从而使得联轴器106能接受鼓驱动件180施加的第一作用力，与鼓驱动件180沿预设旋转方向A同步旋转。联轴器106带动活动件旋转，进而鼓单元104旋转，从而完成驱动动作。
鼓驱动件180处于第二姿态时，当处理盒100需要安装到图像形成装置上时，处理盒100安装到托盘上，然后，处理盒100与托盘一起推入图像形成装置内，关闭前门，鼓驱动件180沿第一方向D1伸出与鼓单元104上的联轴器106相接合，当鼓驱动件180沿第一方向D1伸出过程中，联轴器106上设置的分离部107插入活动件(第一移动部件204与第二移动部件208)之间，接合部108对应于驱动力传递部180d的位置，所以联轴器106可以与鼓驱动件180可直接接合，而后，鼓驱动件180开始沿预设旋转方向A旋转。接合部108与驱动力传递部180d卡接，从而使得联轴器106能接受鼓驱动件180施加的第一作用力，与鼓驱动件180沿预设旋转方向A同步旋转。联轴器106带动活动件旋转，进而鼓单元104旋转，从而完成驱动动作。
当需要将处理盒100从图像形成装置上拆卸下时，鼓驱动件180停止转动，并沿第一方向D1回退，由于联轴器106的分离部107与接合部108均不会对鼓驱动件180的移动造成干涉，从而既可以在保证打印过程正常、 稳定进行的同时，又有利于联轴器106与鼓驱动件180的脱离，防止联轴器106与鼓驱动件180无法顺利脱离的情况，保证使用者可以顺利完成拆卸的动作。
使用此结构，有利于联轴器106与鼓驱动件180的脱离，没有卡扣点或者反向卡合点，防止联轴器106与鼓驱动件180无法顺利脱离的情况，保证使用者可以顺利完成拆卸的动作。
实施例二
参照图15至图20所示，本实施例中，与实施例一不同的是，联轴器106包括第一联轴体110和第二联轴体111，第一联轴体110的第一端与感光鼓105连接，第一联轴体110与第二联轴体111之间设置有弹性件114，使得第二联轴体111的第一端与第一联轴体110的第二端弹性连接，以使得第二联轴体111能沿第一方向D1弹性往复移动，分离部107以及接合部108均形成于第二联轴体111的第二端。
一种可行的实施方式中，第一联轴体110上设有过孔112，第二联轴体111的面向第一联轴体110的一侧凸设有连接轴113，连接轴113间隙配合于过孔112内，弹性件114优选为拉伸弹簧，弹性件114圈套于连接轴113上，弹性件114的相对两端分别与第一联轴体110和第二联轴体111抵接，第二联轴体111向第一联轴体110移动过程中，挤压弹性件114，弹性件114积蓄弹性回复力，使得第二联轴体111能回到初始位置。
在连接轴113凸出于过孔112的一端的外周面上凹设有环形卡槽115，环形卡槽115内嵌设有卡环116，卡环116的直径大于过孔112的内径，卡环116起到了限位作用，以防止第二联轴体111在移动过程中移位脱落。
本实施例的工作过程为：
鼓驱动件180处于第一姿态时，当处理盒100需要安装到图像形成装置上时，处理盒100安装到托盘上，然后，处理盒100与托盘一起推入图像形成装置内，关闭前门，鼓驱动件180沿第一方向D1伸出与鼓单元104相接合。当鼓驱动件180沿第一方向D1伸出过程中，联轴器106上设置的分离部107插入活动件(第一移动部件204与第二移动部件208)之间。由于此时联轴器106上设置的接合部108位于鼓驱动件180上设置的驱动 力传递部180d对应位置的沿预设旋转方向A的上游侧，即接合部108与驱动力传递部180d并未对应接合，此时分离部107下端面与驱动力传递部180d上端面抵接，此时弹性件114被压缩，积蓄弹性回复力，此时鼓驱动件180与联轴器106可以相对运动。
而后，鼓驱动件180在电机驱动下，开始沿预设旋转方向A旋转，由于联轴器106上设置的接合部108位于鼓驱动件180上设置的驱动力传递部180d对应位置的沿预设旋转方向A的上游侧，且鼓驱动件180与联轴器106可以相对运动，因此在经过鼓驱动件180沿预设旋转方向A旋转一定距离后，鼓驱动件180到达第二姿态，即接合部108位于驱动力传递部180d相对应的位置。第一联轴体110不再与鼓驱动件180相抵，此时弹性件114的弹性回复力释放，使得第二联轴体111朝向鼓驱动件180的一侧移动，接合部108与驱动力传递部180d卡接，从而使得联轴器106能接受鼓驱动件180施加的第一作用力，与鼓驱动件180沿预设旋转方向A同步旋转。联轴器106带动活动件旋转，进而鼓单元104旋转，从而完成驱动动作。
鼓驱动件180处于第二姿态时，当处理盒100需要安装到图像形成装置上时，处理盒100安装到托盘上，然后，处理盒100与托盘一起推入图像形成装置内，关闭前门，鼓驱动件180沿第一方向D1伸出与鼓单元104相接合，当鼓驱动件180沿第一方向D1伸出过程中，联轴器106上设置的分离部107插入活动件(第一移动部件204与第二移动部件208)之间，接合部108对应于驱动力传递部180d的位置，所以联轴器106可以与鼓驱动件180可直接接合，而后，鼓驱动件180开始沿预设旋转方向A旋转。接合部108与驱动力传递部180d卡接，从而使得联轴器106能接受鼓驱动件180施加的第一作用力，与鼓驱动件180沿预设旋转方向A同步旋转。联轴器106带动活动件旋转，进而鼓单元104旋转，从而完成驱动动作。
本实施例的处理盒100的其他结构与实施例一相同，在此不再赘述。
实施例三
参照图21至图28所示，本实施例中，与实施例一不同的是，联轴器106包括第一联轴体110和第二联轴体111，第一联轴体110的第一端与 感光鼓105连接，第一联轴体110与第二联轴体111之间设置有弹性件114，使得第二联轴体111的第一端与第一联轴体110的第二端弹性连接，以使得第二联轴体111能沿第一方向D1弹性往复移动，分离部107以及接合部108均形成于第二联轴体111的第二端。
一种可行的实施方式中，第一联轴体110上设有过孔112，第二联轴体111的面向第一联轴体110的一侧凸设有连接轴113，连接轴113间隙配合于过孔112内，弹性件114优选为拉伸弹簧，弹性件114圈套于连接轴113上，弹性件114的相对两端分别与第一联轴体110和第二联轴体111抵接，第二联轴体111向第一联轴体110移动过程中，挤压弹性件114，弹性件114积蓄弹性回复力，使得第二联轴体111能回到初始位置。
在连接轴113凸出于过孔112的一端的外周面上凹设有环形卡槽115，环形卡槽115内嵌设有卡环116，卡环116的直径大于过孔112的内径，卡环116起到了限位作用，以防止第二联轴体111在移动过程中移位脱落。
第一联轴体110与第二联轴体111之间可以沿第一方向D1发生相对移动，但限制第一联轴体110与第二联轴体111之间的相对旋转运动，第一联轴体110与第二联轴体111保持同步转动，一种可行的实施方式中，在第二联轴体111上凸设有引导柱117，引导柱117的外周面上设置有引导肋条118，第一联轴体110的面向第二联轴体111的一侧凹陷设置有引导腔119，过孔112设置的于引导腔119的底壁，引导腔119的侧壁上凹陷设置有引导槽120，引导槽120与引导肋条118均沿着第一方向D1延伸，引导槽120与引导肋条118的位置相对应，引导柱117延伸进引导腔119内，引导肋条118与引导槽120形成间隙配合，从而限制了第二联轴体111与第一联轴体110之间的相对转动，第二联轴体111只能沿第一方向D1往复移动。
本实施例中，分离部107为环状凸起结构，圆环外径大致为10.9mm、内径10.5mm，厚度大致为0.2mm。有利于分离部107插入活动件之间。圆环柱的厚度可沿第一方向D1均匀设置，也可以沿第一方向D1不均匀设置，圆环柱的厚度沿第一方向D1不均匀设置，有利于分离部107与活动件产生摩擦力或过盈力，使得处理盒100与图像形成装置安装更牢固，打印过 程中接合更稳定。
分离部107沿第一方向D1的长度大于等于驱动力传递部180d上表面与鼓驱动件180上表面之间的距离，以确保驱动力传递部180d与接合部108卡接，用于接受驱动力传递部180d施加的第一作用力。具体地，分离部107沿第一方向D1的长度大致为5mm。
接合部108沿预设旋转方向A宽度大于等于驱动力传递部180d沿预设旋转方向A的宽度，有利于接合部108适应驱动力传递部180d宽度，与驱动力传递部180d接合。具体地，接合部108沿预设旋转方向A的周向长度大于等于3.8mm。
接合部108沿第一方向D1的深度大于等于驱动力传递部180d沿第一方向D1的厚度，有利于接合部108与驱动力传递部180d稳定接合，接收驱动力传递部180d施加的驱动力。具体地，接合部108沿第一方向D1的深度大致为0.5mm，以确保接合部108与驱动力传递部180d稳定接合，并能稳定地接受驱动力传递部180d施加的驱动力。
本实施例的工作过程为：
鼓驱动件180处于第一姿态时，当处理盒100需要安装到图像形成装置上时，处理盒100安装到托盘上，然后，处理盒100与托盘一起推入图像形成装置内，关闭前门，鼓驱动件180沿第一方向D1伸出与鼓单元104相接合。当鼓驱动件180沿第一方向D1伸出过程中，联轴器106上设置的分离部107插入活动件(第一移动部件204与第二移动部件208)之间。由于此时联轴器106上设置的接合部108位于鼓驱动件180上设置的驱动力传递部180d对应位置的沿预设旋转方向A的上游侧，即接合部108与驱动力传递部180d并未对应接合，此时分离部107下端面与驱动力传递部180d上端面抵接，此时弹性件114被压缩，积蓄弹性回复力，此时鼓驱动件180与联轴器106可以相对运动。
而后，鼓驱动件180在电机驱动下，开始沿预设旋转方向A旋转，由于联轴器106上设置的接合部108位于鼓驱动件180上设置的驱动力传递部180d对应位置的沿预设旋转方向A的上游侧，且鼓驱动件180与联轴器106可以相对运动，因此在经过鼓驱动件180沿预设旋转方向A旋转一 定距离后，鼓驱动件180到达第二姿态，即接合部108位于驱动力传递部180d相对应的位置。第一联轴体110不再与鼓驱动件180相抵，此时弹性件114的弹性回复力释放，使得第二联轴体111朝向鼓驱动件180的一侧移动，接合部108与驱动力传递部180d卡接，从而使得联轴器106能接受鼓驱动件180施加的第一作用力，与鼓驱动件180沿预设旋转方向A同步旋转。联轴器106带动活动件旋转，进而鼓单元104旋转，从而完成驱动动作。
鼓驱动件180处于第二姿态时，当处理盒100需要安装到图像形成装置上时，处理盒100安装到托盘上，然后，处理盒100与托盘一起推入图像形成装置内，关闭前门，鼓驱动件180沿第一方向D1伸出与鼓单元104相接合，当鼓驱动件180沿第一方向D1伸出过程中，联轴器106上设置的分离部107插入活动件(第一移动部件204与第二移动部件208)之间，接合部108对应于驱动力传递部180d的位置，所以联轴器106可以与鼓驱动件180可直接接合，而后，鼓驱动件180开始沿预设旋转方向A旋转。接合部108与驱动力传递部180d卡接，从而使得联轴器106能接受鼓驱动件180施加的第一作用力，与鼓驱动件180沿预设旋转方向A同步旋转。联轴器106带动活动件旋转，进而鼓单元104旋转，从而完成驱动动作。
本实施例的处理盒100的其他结构与实施例一相同，在此不再赘述。
实施例四
参照图29以及图30所示，本实施例中，接合部108包括相连通的第一槽段121和第二槽段122，第二槽段122的宽度大于第一槽段121的宽度，第二槽段122较第一槽段121更靠近感光鼓105，第二槽段122的宽度与驱动力传递部180d的宽度相适应，当联轴器106与鼓驱动件180接合时，第二槽段122与驱动力传递部180d卡接，用于接受驱动力传递部180d施加的驱动力，此时第二槽段122的底壁与驱动力传递部180d的表面抵接，产生一定的摩擦力，力的方向与驱动力传递部180d施加的第一作用力方向相反，保证打印过程中联轴器106与鼓驱动件180稳定接合。
本实施例的处理盒100的其他结构与实施例一相同，在此不再赘述。
实施例五
参照图31以及图32所示，本实施例中，与实施例二不同的是，本实施例中，联轴器106上的接合部108只设有一个，分离部107包括凸设于联轴器106第二端的环状凸起结构，接合部108为凸设于环状凸起结构端面的片状凸起结构。
本实施例中，分离部107为环状凸起结构，其外径大致为10.9mm、内径10.5mm，厚度大致为0.2mm。有利于分离部107插入活动件之间。圆环柱的厚度沿第一方向D1均匀设置，也可以沿第一方向D1不均匀设置，圆环柱的厚度沿第一方向D1不均匀设置，有利于分离部107与活动件产生摩擦力或过盈力，使得处理盒100与图像形成装置安装更牢固，打印过程中接合更稳定。
分离部107沿第一方向D1的长度大于等于驱动力传递部180d上表面与鼓驱动件180上表面之间的距离，以确保驱动力传递部180d与接合部108卡接，用于接受驱动力传递部180d施加的第一作用力。具体地，分离部107沿第一方向D1的长度大致为5mm。
优选地，分离部107沿第一方向D1有一定宽度，有利于接合部108接受驱动力传递部180d施加的第一作用力。具体地，接合部108凸设形成于分离部107端面，使得分离部107在接合部108的周向形成片状凸起结构，片状凸起结构沿预设旋转方向A的周向长度大于等于5mm。优选地，片状凸起结构沿第一方向D1的高度大于等于驱动力传递部180d沿第一方向D1的厚度，有利于接合部108与驱动力传递部180d稳定接合，用于稳定接受驱动力传递部180d施加的第一作用力。具体地，分离部107的片状凸起结构沿第一方向D1的高度大于0.5mm，以确保所接合部108的槽体结构与驱动力传递部180d稳定接合，并且能稳定地接受驱动力传递部180d施加的第一作用力。

定位部180i上还设有传递斜面215。当鼓驱动件200沿第一方向D1伸出与联轴器106接合时，挤压部123推压活动件向与第一方向D1相反的方向移动，以减小或消除鼓驱动件200转动时产生的异响，分离部107插入到第一移动部件204和第二移动部件208之间的第一间隙214中，传递斜面215与驱动力接收块124的驱动力接收面125抵接，以接收驱动力。
