实施例一
如图1、图2及图3所示，本发明实施例的驱动力接收组件包括动力接收部1、动力传递部2、驱动配合部3以及位置调节装置。本发明实施例驱动力接收组件用于接收图像形成装置中驱动头的旋转力，并将旋转力通过设置于感 光鼓端部的感光鼓齿轮传递给感光鼓，以带动感光鼓旋转，该旋转力同时还通过设置于感光鼓端部的感光鼓齿轮传递给处理盒中其它的旋转部件。本实施例的驱动配合部3为分体式结构，其包括与动力传递部2相配合的第一装配部3-1以及与感光鼓相配合的第二装配部3-2。本实施例第二装配部3-2是与设置于感光鼓端部的感光鼓齿轮10内壁相配合，但第二装配部3-2也可以直接和感光鼓本体配合，从而将驱动力传递给感光鼓，以带动感光鼓旋转。
一对对称设置的动力接收部1对称设置于动力传递部2上，动力接收部1向上突出于动力传递部2，动力接收部1用于与图像形成装置中的驱动头相卡合，并从图像形成装置侧接收动力。驱动力接收组件(动力传递部)的旋转中心线(轴线)与感光鼓的轴线重合。驱动力接收组件中可以包含多对对称设置的动力接收部1，多对动力接收部1之间在与驱动头啮合部相啮合时，只选择其中一对对称设置的动力接收部1与驱动头啮合部相啮合。由于动力接收部为对称布置，因此两个动力接收部的受力点A(与驱动头相接触的接触点)间的连线必然与驱动力接收组件(动力传递部)的旋转中心线b(轴线)垂直相交。
作为本发明的一个优选实施例，本实施例中动力接收部1的底部为球形的铰接部1-1，动力接收部1通过铰接部1-1铰接于动力传递部2上，受力时，动力接收部1可绕铰点转动，使得驱动力接收组件和驱动头脱离时可进行位置的微调节，更便于动力接收部与驱动头脱离。同时，在两动力接收部1之间设置有具有弹性的回弹装置5，回弹装置5的两端分别与动力接收部1相连，通过其弹力作用使两个动力接收部1处于一个固定的状态，当动力接收部1绕铰点转动并完成与驱动头的脱离后，可在回弹装置5的弹力作用下恢复至原位。本实施例的回弹装置5采用金属弹片，在金属弹片的两端加工有与动力接收部相配合的安装孔，金属弹片的两端套在动力接收部1的铰接部1-1的上方，与动力接收部1相连。回弹装置也可以采用弹簧或橡胶弹片或橡胶圈等具有弹性的构件，只要能为动力接受部提供复位的作用力即可。
动力传递部2上设置有一插销2-1，本实施例的插销位于动力传递部的中下部，插销2-1穿过动力传递部2且其轴线垂直于动力传递部2的轴线(旋转中心线)。另外，端部突出于动力传递部表面且轴线垂直于动力传递部轴线的 突起也可以理解为插销的另一种实现方式。本实施例的位置调节装置为扭簧，扭簧4作为动力传递部的回转力(预旋转力)提供装置，为动力传递部提供回转的作用力。扭簧4一端固定在插销2-1上(亦即动力传递部)，另一端固定在驱动配合部3上。插销的作用一方面用于接受使动力传递部偏转的作用力，另一方面也用于限位。本实施例的第一装配部3-1为具有一沿其轴线设置的容纳腔的圆柱体，动力传递部2插设于第一装配部3-1的容纳腔内、且上部伸出于第一装配部3-1外，动力传递部2可在第一装配部3-1内绕其自身的轴线转动。扭簧4套在第一装配部3-1外。
第一装配部3-1设置于第二装配部3-2之上，第一装配部3-1和第二装配部3-2之间通过单向啮合的面齿轮相连，即第一装配部的底面与第二装配部的上表面为单向啮合的齿面，当第一装配部受力沿预定的驱动旋转方向转动时，其与第二装配部间的啮合关系可带动第二装配部一同旋转(图8、图2)，从而带动感光鼓旋转；当第二装配部沿反向转动时，其与第二装配部之间会出现打滑现象，则无法带动第二装配部一同旋转，从而实现感光鼓只能单向旋转的目的。
本实施例在第一装配部3-1底部设置有扭簧固定部3-1b，扭簧的另一端固定在第一装配部3-1的扭簧固定部3-1b上。第二装配部3-2外壁上设置有一对向外突出的固定部3-2a，感光鼓齿轮内设置有与固定部3-2a配合的安装槽(未图示)，驱动配合部3安装在感光鼓齿轮10内时，固定部3-2a设置于感光鼓齿轮10内的安装槽内，从而与感光鼓齿轮装配固定在一起，当第二装配部3-2转动时可带动感光鼓齿轮一起转动。当第二装配部与感光鼓本体直接配合时，安装槽可设置于感光鼓本体端部内壁上，驱动配合部安装在感光鼓本体端部内，固定部设置于安装槽内，从而与感光鼓装配固定在一起，当第二装配部转动时带动感光鼓一起转动。
作为一个优选的实施方案，本实施例在第一装配部3-1周壁上与插销2-1位置对应处加工有沿周向设置的通槽，通槽的端壁构成本实施例的旋转限位部3-1a。插销2-1的两端穿出通槽并伸出于第一装配部3-1之外，当动力传递部2沿自身轴线转动时，插销2-1可在通槽内移动，当插销2-1抵到通槽的端壁 3-1a时，因受端壁3-1a的限制而无法单独移动，从而动力传递部2可推动第一装配部3-1一起转动。
驱动力接收组件通过齿轮端盖11和压环12装配在感光鼓齿轮10上，感光鼓齿轮10固定在处理盒感光鼓的端部。压环12作为轴向限位构件，装配在第二装配部3-2位置处，通过限制第二装配部在轴向上的移动，防止驱动力接收组件轴向脱出。进一步的，在驱动配合部3和感光鼓齿轮10之间设置有轴向作用力装置6，本实施例的轴向作用力装置6为弹簧，其位于第二装配部3-2(驱动配合部3)底部与感光鼓齿轮10端壁之间(图4)，轴向作用力装置6可使驱动力接收组件沿感光鼓轴线产生轴向位移。轴向作用力装置6也可以为弹片或橡胶弹簧或橡胶圈等具有弹性的构件。
下面结合附图对本发明驱动力接收组件与图像形成装置的驱动头的配合过程进行说明。参照图6和图7A、7B，图像形成装置的驱动头100上通常设置有一对突出的啮合部100a，啮合部与驱动力接收组件的动力接收部卡合后进行驱动力的传递。驱动头上两个啮合部100a的中心点间的连线a1与驱动头的旋转中心线a垂直相交(图6)。设驱动头100的直径为D，啮合部100a突出于驱动头侧面的高度为H，图7B中的a为驱动头100的旋转中心线a垂直于纸平面的投影(形成驱动头在纸平面投影的旋转中心)，b为动力传力部2的旋转中心线垂直于纸平面的投影(形成动力传动部在纸平面投影的旋转中心)。当处理盒(驱动力接收组件)在落入机器、并即将与驱动头100接触时，本发明的动力传递部2在没有受到外力的情况下，只有扭簧的弹力作用于动力传递部2上，位置调节装置采用扭簧等具有弹性的构件通过自身积蓄回转势能，在动力传递部上施加作用力，使动力传递部2保持在某一预定位置，将处理盒落入机器后驱动力接收组件处于该预定位置时的状态定义为未装配状态。
如图7A，驱动力接收组件处于未装配状态时，驱动头100上两个啮合部100a的中心点间的连线a1与两个动力接收部1的受力点A之间的连线M形成一个夹角C，亦即，过任意一个啮合部100a的中心点与驱动头旋转中心线的垂直相交线a1与过任意一个动力接收部的受力点和动力传递部旋转中心线的垂直相交线M形成一个固定的夹角C。本实施例中，所述过啮合部的中心点和驱动头旋转中心线的垂直相交线和驱动头旋转中心线与动力传递部旋转中心线间 的垂直连线在垂直于驱动头旋转中心线与动力传递部旋转中心线的平面上的投影重合(在本实施例的图7A中为在纸平面上的投影重合)。通过夹角C，在处理盒装机时驱动头100可以顺畅的进入两个动力接收部1之间，不会被动力接收部卡住。优选的，过两驱动头100上啮合部100a的中心点和驱动头旋转中心线的垂直相交线a1与过两个动力接收部1的受力点A和动力传递部旋转中心线间的垂直连线M沿顺时针方向的夹角C大于30度、小于90度。驱动力接收组件以过啮合部100a的中心点和驱动头旋转中心线的垂直相交线a1与过动力接收部的受力点和动力传递部旋转中心线的垂直相交线M形成固定角度的方式与驱动头进行啮合，此处所说的进行啮合是指处理盒装入图像形成装置后，驱动力接收组件即将与驱动头接触时的状态，此时驱动头与驱动力接收组件还没有接触配合在一起。
如图7B，当驱动力接收组件处于未装配状态时，两个动力接收部1在与处理盒安装方向垂直的平面S上的投影区域不重合(无交集，无重叠部分)，且两个动力接收部1在与处理盒安装方向垂直的平面S上的投影区域中任意两点间连线长度的最小值L满足：D/2≤L≤D+H，即在同一投影平面上一个投影区域中的任意一点与另一投影区域中的任意一点间连线长度的最小值L满足：D/2≤L≤D+H。其中，D为驱动头垂直于驱动头旋转轴线的最大外径，H为驱动头啮合部突出于啮合部安装位置的驱动头轮廓面最外点的高度。通过向动力传递部2施加一个使其旋转的作用力，使动力传递部处于一个预定的位置，处理盒装机时驱动头100可以顺畅的进入两个动力接收部1之间，不会被动力接收部卡住。驱动力接收组件以两个动力接收部1在与处理盒安装方向垂直的平面S上的投影区域不重合且两投影区域上任意两点间连线长度的最小值L满足D/2≤L≤D+H的方式与驱动头进行啮合，此处所说的进行啮合是指处理盒装入图像形成装置后，驱动力接收组件即将与驱动头接触时的状态，此时驱动头与驱动力接收组件还没有接触配合在一起。
当处理盒装入完毕后，驱动头100先自行转动一定角度，如图8所示，随着驱动头100的旋转，驱动头的啮合部100a与动力接收部1在动力接收部的受力点位置处相接触，并卡合在一起，此时驱动头与驱动力接收组件的装配完成，装配完成后过啮合部100a的中心点与驱动头旋转中心线的垂直相交线a1 与过动力接收部的受力点与动力传递部旋转中心线的垂直相交线L形成角度会改变，但在进行啮合时动力传递部在只受位置调节装置的作用力作用时，过啮合部100a的中心点与驱动头旋转中心线的垂直相交线a1与过动力接收部的受力点与动力传递部旋转中心线的垂直相交线M间均保持形成固定角度C的状态不变；驱动头100继续转动时，就会带动动力传递部2一起旋转，此时动力传递部2上的插销2-1也会随动力传递部一起旋转，直至动力传递部2上的插销2-1移动至旋转限位部3-1a处，动力传递部2进一步带动驱动配合部3旋转，将驱动头的旋转驱动力传递给感光鼓齿轮，从而实现通过驱动力接收组件带动感光鼓旋转。
本实施例中设置插销来固定扭簧，但扭簧也可以直接固定在动力传递部2上，只要实现可以为动力传递部提供偏转的作用力，使过啮合部100a的中心点与驱动头旋转中心线的垂直相交线a1与过动力接收部的受力点与动力传递部旋转中心线的垂直相交线M始终保持固定的角度C，和/或，使两个动力接收部1在与处理盒安装方向垂直的平面s上的投影区域不重合且两投影区域上任意两点间连线长度的最小值L满足D/2≤L≤D+H即可。除了可以采用扭簧作为提供偏转力的位置调节装置外，也可以采用弹片、橡胶圈等其他弹性构件。本发明过啮合部的中心点与驱动头旋转中心线的垂直相交线a1与过动力接收部的受力点与动力传递部旋转中心线的垂直相交线L之间形成的角度C是固定的，不是处理盒在装机过程中随意形成的，并且通过该角度，使得驱动力接收组件的动力接收部在与驱动头啮合的过程中可以形成供驱动头顺利通过的空间，驱动头不会此过程中与驱动力接收组件发生卡住等情况，从而保证处理盒落机顺畅。
参照图5，进一步的，本实施例还包括限位调整装置7，限位调整装置7为固定在齿轮端盖11上的卡簧，卡簧的一端抵在齿轮端盖的侧壁上。动力传递部2上设置有突出于其外壁的限位凸起2-2，卡簧的另一端抵在动力传递部2的限位凸起2-2上，通过限位调整装置调整动力传递部与感光鼓轴线间的位置。限位凸起2-2包括与卡簧抵顶的第一表面s1和与第一表面s1顶部相连的第二表面s2，第一表面和第二表面均与动力传递部的侧面相连，第一表面s1为限位凸起的正面时，则第二表面s2为限位凸起的背面。第一表面s1为限位 抵顶面，本实施例的第一表面s1沿动力传递部2的径向设置，第二表面s2为一斜面，从第一表面s1顶部倾斜延伸。卡簧7的一端卡合抵接在限位凸起2-2的第一表面s1上，可避免动力传递部2的轴线偏离感光鼓的轴线；而且动力传递部2转动时，由于第二表面s2为斜面，卡簧端部可沿着第二表面s2顺利通过，不会被卡住。
实施例二
如图10所示，图10中箭头所示方向为预定的旋转驱动方向。本实施例与实施例一不同的地方在于：本实施例的限位调整装置7为一端固定在齿轮端盖11上的弹性摆臂，弹性摆臂由具有弹性的材料制成，例如金属弹片或橡胶体等。动力传递部2上设置有突出于其外壁的限位凸起2-2，本实施例的限位凸起2-2沿垂直于动力传递部轴线方向的截面形状为梯形，但也可以为矩形。弹性摆臂的轴线a2与限位凸起中心点和动力传递部旋转中心线间的连线a3沿动力传递部旋转方向上的夹角大于0度，小于90度。弹性摆臂的一端固定在齿轮端盖11上，当动力传递部2旋转过程中，限位凸起2-2经过弹性摆臂时，弹性摆臂被限位凸起2-2向外顶，从而限位凸起2-2可顺利通过弹性摆臂，限位凸起2-2离开弹性摆臂后，弹性摆臂在自身弹力作用下恢复原位。当动力传递部2停止旋转时，弹性摆臂的自由端抵在限位凸起2-2上，对其进行限位。
实施例三
如图11所示，图11中箭头所示方向为预定的旋转驱动方向。本实施例与实施例二不同的地方在于，限位调整装置包括旋转摆臂7和一弹性构件7a，旋转摆臂铰接于齿轮端盖11上，并可绕铰点转动，弹性构件7a设置于旋转摆臂与齿轮端盖侧壁之间、分别与旋转摆臂及齿轮端盖侧壁相连。旋转摆臂的轴线与限位凸起中心点和动力传递部旋转中心线间的连线沿动力传递部旋转方向上的夹角大于0度，小于90度。动力传递部2在旋转过程中，限位凸起2-2经过旋转摆臂时，旋转摆臂会被限位凸起2-2向外顶，从而限位凸起2-2可顺利通过旋转摆臂，当动力传递部2经过旋转摆臂后，旋转摆臂在弹性构件7a的 作用下回位。当动力传递部2停止旋转时，旋转摆臂的自由端抵在限位凸起2-2上，对其进行限位。
实施例四
如图12所示，图12中箭头所示方向为预定的旋转驱动方向。本实施例与实施例一不同的地方在于：本实施例的驱动配合部3为一体式结构，在驱动配合部3上设置有突出于其表面的单向限位部3a，本实施例在驱动配合部3上设置了一对对称布置的单向限位部3a。在感光鼓齿轮10内设置有位置与驱动配合部3上的单向限位部3a位置相对应的弹性限位部10a，弹性限位部10a铰接于感光鼓齿轮10内壁的安装部10c上，弹性限位部10a可绕其铰点转动，在弹性限位部10a与安装部10c之间设置有弹性件10b，弹性件10b的弹力作用于弹性限位部10a上，使其与安装部10c相接触。弹性限位部10a靠近安装部10c时的移动方向与预定的驱动旋转方向为同向，弹性限位部10a远离安装部10c时的移动方向与预定的驱动旋转方向相反。
安装部10c突出于感光鼓齿轮10的内壁，当驱动配合部3沿预定的驱动旋转方向转动、并转至单向限位部3a与弹性限位部10a相接触时，单向限位部3a会被弹性限位部10a及安装部10c阻挡，从而带动感光鼓齿轮10一起旋转；而当驱动配合部3不按驱动旋转方向旋转(反向旋转)、并转至单向限位部3a与弹性限位部10a相接触时，单向限位部3a可将弹性限位部10a顶开，使其远离安装部10c，从而单向限位部3a可以通过弹性限位部10a，当单向限位部3a离开后，弹性限位部10a在弹性件10b的弹力作用下回到原位，此时驱动配合部3不能带动感光鼓齿轮10一同旋转，实现了感光鼓只能单向旋转的目的。
实施例五
如图13所示，本实施例与实施例四不同的地方在于：本实施例的弹性限位部10a可沿感光鼓齿轮10径向往复移动地设置于感光鼓齿轮10内。感光鼓齿轮10内设置有沿其径向布置的安装部10c，弹性限位部10a设置于安装部10c上，并可在安装部10c上(内)沿径向移动，弹性件10b设置于弹性限位 部与安装部10c底壁(或感光鼓齿轮内壁)之间。弹性限位部10a的自由端部具有与驱动配合部3上的单向限位部3a相接触的抵接面s3，以及与抵接面s3相连的顶端斜面s4，顶端斜面s4可以是平面或弧面。弹性限位部往复移动方向与顶端斜面s4之间沿预定驱动旋转方向上的夹角小于90°。
当驱动配合部3沿预定驱动旋转方向绕其轴线旋转时，单向限位部3a与抵接面s3相接触，从而被弹性限位部10a挡住，使其可以带动感光鼓齿轮10一起转动；当驱动配合部3不沿预定驱动旋转方向绕其轴线旋转时(反向旋转)，单向限位部3a与顶端斜面s4相接触，单向限位部3a可顺着顶端斜面s4继续转动，从而将弹性限位部10a向感光鼓齿轮内壁方向压，使弹性限位部10a靠近感光鼓齿轮内壁，便可顺利通过弹性限位部10a，单向限位部3a离开弹性限位部10a后，弹性限位部10a在弹性件10b的作用下向远离感光鼓齿轮内壁的方向移动回位，此时驱动配合部3不能带动感光鼓齿轮10一同旋转，实现了感光鼓只能单向旋转的目的。
实施例六
如图14所示，本实施例与实施例四不同的地方在于：本实施例的弹性限位部10a为弹性臂，弹性限位部10a的一端连接于感光鼓齿轮10内壁上，在弹性限位部10a与感光鼓齿轮内壁之间设置有弹性件10b。在驱动配合部3上设置有突出于其表面的单向限位部3a。弹性限位部10a和单向限位部3a之间的接触点B与驱动配合部3中心线间的连线a4与弹性臂的轴线a5间沿反向上的夹角小于100度。这里的反向是指与预定驱动旋转方向相反。
当驱动配合部3沿预定驱动旋转方向(图14中箭头所示方向)绕其轴线旋转时，单向限位部3a与弹性臂相接触，从而被弹性臂挡住，使其可以带动感光鼓齿轮10一起转动；当驱动配合部3不沿预定驱动旋转方向绕其轴线旋转时(反向旋转)，单向限位部3a会将弹性臂向感光鼓齿轮内壁方向压，将其顶开，从而单向限位部3a可继续转动，单向限位部3a离开弹性臂后，弹性臂在弹性件10b的作用下向远离感光鼓齿轮内壁的方向移动回位，此时驱动配合部3不能带动感光鼓齿轮10一同旋转，实现了感光鼓只能单向旋转的目的。
实施例七
如图15所示，本实施例与实施例一不同的地方在于：本实施例的动力传递部上没有设置扭簧，位置调节装置为设置于齿轮端盖11上的摆杆联动机构，摆杆联动机构包括摆杆4-1、连杆4-2、复位部件4-3、碰触块4-4及转轴4-5。摆杆4-1通过转轴4-5设置于齿轮端盖11上，摆杆4-1可绕转轴4-5转动。摆杆4-1上设置有滑槽4-1a。碰触块4-4与连杆4-2相连，碰触块4-4可在垂直于动力传递部件旋转中心线的平面内移动，碰触块4-4同时还位于摆杆4-1上的滑槽4-1a内。本实施例的碰触块4-4位于开设在齿轮端盖11上的导轨或导槽(未图示)内，并可沿导轨或导槽往复移动，导轨或导槽可以是直线形或弧形。复位部件4-3一端固定在齿轮端盖11上、另一端与摆杆4-1相连，用于使连杆4-2回位。
如图16所示，当处理盒装机时，摆杆4-1会碰到机器上的挡块200，并被挡块200所阻挡，随着处理盒沿安装方向移动，摆杆4-1因受挡块200的阻挡而绕转轴4-5转动，并推动碰触块4-5移动，碰触块4-5移动时带动连杆4-2沿处理盒的安装方向移动，从而使连杆4-2与动力传递部2上的插销2-1相接触，并随着连杆4-2的移动推动动力传递部2绕自身轴线旋转，使得驱动头上两个啮合部的中心点间的连线与两个动力接收部1的受力点之间的连线形成夹角C，和/或，使得两个动力接收部在与处理盒安装方向垂直的平面上的投影区域不重合，且两个动力接收部在与处理盒安装方向垂直的平面上的投影区域上任意两点间连线长度的最小值L满足：D/2≤L≤D+H。
如图17所示，当将处理盒取出时，摆杆4-1也会碰到机器上的挡块200，随着处理盒沿取出方向移动，摆杆4-1绕转轴4-5转动，此时的转动方向与装机时的转动方向相反，并同时推动碰触块4-5移动，以带动连杆沿处理盒的去处方向移动，此时，可顺利将处理盒取出。
实施例八
如图18所示，本实施例与实施例七不同的地方在于：本实施例的复位部件4-3一端固定于齿轮端盖11上、另一端与连杆4-2相连，复位部件4-3的 轴线与连杆4-2的轴线平行。摆杆4-1绕转轴4-5转动时，可通过位于其滑槽4-1a内的碰触块4-4带动连杆4-2沿处理盒的安装方向(图18中实心箭头所示方向)平动，从而使连杆4-2与动力传递部2上的插销2-1相接触，使得驱动头上两个啮合部的中心点间的连线与两个动力接收部1的受力点之间的连线形成夹角，和/或，使得两个动力接收部在与处理盒安装方向垂直的平面上的两投影区域上任意两点间连线长度的最小值L满足：D/2≤L≤D+H。
本发明通过设置位置调节装置，使得在处理盒装机后、即将与驱动头接触时，动力接收部处于特定的位置，在该位置处啮合部的中心点与驱动头旋转中心线间垂直于驱动头旋转中心线的连线与动力接收部的受力点与动力接收部旋转中心线间垂直于驱动力接收组件的旋转中心线的连线形成夹角，和/或，在该位置处两个动力接收部在与处理盒安装方向垂直的平面上的投影区域不重合，且两个动力接收部在与处理盒安装方向垂直的平面上的投影区域上任意两点间连线长度的最小值L满足：D/2≤L≤D+H，从而可以在动力接收部之间形成空间，让驱动头可以顺畅的进入，不会发生动力接收部与驱动头卡住的情况，而且可以稳定地进行驱动力传递。
本说明书中各个部分采用递进的方式描述，每个部分重点说明的都是与其它部分的不同之处，各个部分之间相同或相似部分互相参见即可。这些零部件之间的组合关系并不只是实施例所公开的形式，对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽范围。
