技术领域
本发明涉及电子照相成像领域，具体地说，涉及电子照相成像设备内的用于传递驱动力的一种驱动组件及具有该驱动组件的显影盒。
背景技术
电子照相成像设备，还可以称为电子成像装置，其成像原理为，首先在涂有光敏材料的感光鼓或感光带上均匀充电，然后用激光束对其表面进行曝光，受照射部分的电荷消失，未受照射部分仍然携带电荷形成静电潜像，然后利用显影辊等构件将碳粉等显影剂提供至该静电潜像，以进行显影，然后再转印至打印介质上，并通过加热进行定影，从而在打印介质上形成稳定的图像。
电子照相成像设备内一般会可拆卸地安装有显影盒，出于不同的设计理念，各电子照相设备生产厂商会将或多或少的处理构件集成在显影盒内，如有的将感光鼓、显影装置、充电装置及清洁装置都集成在一起形成一体盒，有的将感光鼓和充电装置集成在一起或将感光鼓和显影装置集成在一起各种的分体盒，无论何种集成方式，只要盒内具有在成像过程中需要旋转的处理构件，都需要从电子照相成像设备接收驱动力，具体地，显示盒从电子照相成像设备主体侧的驱动头或驱动部件接收驱动力，以驱动处理构件旋转。
现有一种驱动件为万向节式设计，一端设置在显影盒端部的一圆筒件内，另一端向显影盒外突出，用于与电子照相成像设备内的驱动轴接合，在安装至电子照相成像设备或从电子照相成像设备拆卸时，相对于圆筒件的轴向，驱动件向一侧倾斜，以避免与驱动轴形成干涉。圆筒件可设置在感光鼓或显影辊的端部，万向节接收驱动力后可直接带动感光鼓或显影辊旋转，圆筒件也可设置在与感光鼓或显影辊轴向平行的其他位置，然后通过齿轮组等将驱动力传递至感光鼓或显影辊等处理构件。但这种万向节驱动件极易从圆筒件内脱落，从而无法稳定地传递驱动力。
为解决万向节驱动件易于脱落的问题，现有不少显影盒的驱动件采用的可轴向移动的联接件设置在圆筒件内，安装或拆卸时，受电子照相成像设备内的驱动轴(即驱动头)抵接， 联接件向内运动以避免与驱动轴干涉，当显影盒安装到位时，利用弹簧或气压方式使得联接件向外运动并与电子照相成像设备的驱动轴接合，从而驱动感光鼓或显影辊以及其他接受旋转驱动力的部件。但有时由于联接件的轴向移动受电子照相成像设备内其他结构的限制，从而显影盒不易顺利拆卸。若采用强力装入或者取出会使得驱动件与电子照相成像设备的驱动轴的接合存在不稳定风险，无法稳定地传递驱动力。
201120045210.4号中国发明专利公开一种驱动组件，驱动触头通过枢轴和回弹复位件连接在支架体的缺口处。当驱动组件从成像设备驱动头接受驱动力旋转时，作用力通过驱动触头、枢轴传递到支架体，驱动力传递不稳定。另外，由于缺口处的空间限制，枢轴通常较细，当驱动组件从成像设备驱动头接受驱动力旋转时，旋转产生的扭矩极易损坏枢轴。受缺口空间限制，驱动触头及回弹复位件的安装亦不方便。
发明内容
本发明的主要目的是提供一种操作简便、结构稳定、显影盒安装及拆卸方便，并实现驱动力传递稳定的驱动组件；
本发明的另一目的是提供一种具有操作简便、结构稳定、显影盒安装及拆卸方便，并实现驱动力传递稳定的显影盒。
为实现上述主要目的，本发明提供了一种驱动组件，驱动组件适于设置在显影盒的一个端部，至少包括一个可与电子成像装置的驱动头相配合的联接件，其中，联接件包括：套筒，在套筒的远离显影盒的端部设有径向向外突出的突出部分，突出部分上设置有开口向外的限位槽；导杆，与套筒同轴且可相对于套筒的轴向往复移动，具有位于套筒内腔的第一端和能够从套筒内腔伸出的第二端；至少一个接合爪，铰接在导杆的第二端；在驱动组件接收驱动力转动时，限位槽的侧面与接合爪的侧面接触。
由以上方案可见，驱动组件通过联接件与电子照相成像设备的驱动轴接合以接受来自电子照相成像设备的驱动力。在传递驱动力的过程中，通过限位槽的侧面和接合爪的侧面相接触，驱动力直接由接合爪传递至套筒，一方面减少了驱动力传递的环节，另一方面亦可保证接合爪不易于从限位槽中脱出，从而确保驱动力的传递更稳定。接合爪的一端铰接在导杆的第二端，使接合爪可绕垂直于导杆轴向的轴线转动，在显影盒从电子照相成像设备内拆卸时，驱动组件相对驱动轴运动，驱动轴迫使接合爪偏转，可避免接合爪与驱动轴形成干涉，使驱动轴与驱动组件脱离，方便显影盒的拆卸。接合爪的偏转使导杆轴向向外移动，使接合爪的偏转角度变大，进一步避免与驱动轴形成干涉。
在其中一个实施例中，接合爪至少为两个，至少两个所述接合爪相对于所述导杆对称设置，通过枢轴或铰链铰接在导杆的第二端，接合爪的自由端沿导杆的轴向向外突出。
由以上方案可见，至少两个接合爪对称设置并通过枢轴或铰链安装在导杆的第二端，不但安装方便，且可使导杆及驱动组件受力平衡，驱动力传递进一步稳定。枢轴连接时，枢轴可以设置为与导杆的轴线相垂直。限位槽的侧面与接合爪抵接实现驱动力自导杆向套筒的传递，导杆的接合爪可绕枢轴转动，在与驱动轴抵接时，接合爪绕枢轴转动，导杆轴向向外移动，接合爪的偏转角度变大，接合爪的轴向突出距离变小，可进一步避免与驱动轴形成干涉，驱动轴与驱动组件脱离，从而操作简便、结构稳定、显影盒安装及拆卸方便，并可实现驱动力的稳定传递。
在其中一个实施例中，伴随导杆向外的轴向移动，相对于导杆的第二端，接合爪相对所述导杆的轴线的偏转角度变大，接合爪沿导杆的轴向向外突出的距离变小。
由以上方案可见，在接合爪绕枢轴转动时，接合爪在导杆轴线所在的平面内或与导杆轴线平行的平面内转动，在导杆相对套筒的位置改变时，接合爪的偏转角度改变幅度较大，接合爪的轴向突出距离改变幅度较大，从而易于实现驱动轴与驱动组件的脱离或接合。
在其中一个实施例中，驱动组件还包括适于设置在显影盒一端部的圆筒件，圆筒件内设置有作用力装置；其中，联接件具有位于圆筒件内的连接端和从圆筒件伸出至显影盒外的自由端，联接件在作用力装置施加在联接件的连接端的力的作用下可沿圆筒件的轴向移动；圆筒件上设置有用于防止联接件的连接端从圆筒件内脱出的第一限位结构。
从以上方案可见，安装或拆卸时，受电子照相成像设备内的驱动轴抵接，联接件向内运动以避免与驱动轴干涉，当显影盒安装到位时，利用作用力装置推动联接件向外运动并与电子照相成像设备的驱动轴接合，稳定地传递驱动力。在圆筒件上设置用于防止联接件的连接端从圆筒件内脱出的第一限位结构，以使联接件不易从圆筒件内脱落。
在其中一个实施例中，套筒内设置有向导杆施加轴向作用力的偏压装置。由以上方案可见，利用偏压装置使导杆相对于套筒位于初始位置。偏压装置向导杆施加的轴向作用力可以是轴向向外的作用力也可以是轴向向内的作用力。当偏压装置向导杆施加的是轴向向外的作用力时，偏压装置使导杆位于轴向靠外的位置，此时接合爪的偏转角度大，接合爪的轴向突出距离小，在与驱动轴接合时，驱动轴与接合爪抵接使导杆向内移动，突出部分抵接接合爪使接合爪偏转角度变小，接合爪的轴向突出距离变大并与驱动轴的突起接触以传递驱动力。当偏压装置向导杆施加的是轴向向内的作用力时，偏压装置使导杆位于轴向靠内的位置，此时接合爪的偏转角度小，接合爪的轴向突出距离大，在驱动轴与驱动组件脱离时，驱动轴与接合爪抵接并使接合爪转动，带动导杆克服偏压装置的偏压力轴向向外移动，接合爪的轴向突出距离变小，驱动轴可与接合爪实现相互脱离。其中，偏压装置还可以起到限位的作用，限制导杆相对所述套筒的轴向移动距离。另外，套筒内或导杆上也可以设置有用于限制导杆相对套筒轴向移动的第二限位结构。第二限位结构可使导杆不易于从套筒内脱出，保持套筒 与导杆的连接并可相对轴向移动。其中，偏压装置也可为第二限位结构的一种实施方式。
在其中一个实施例中，偏压装置为金属弹性结构、非金属弹性材料、磁性装置、气压或液压密封装置中的一种或多种。由以上可见，偏压装置只向可提供轴向方向的偏压力即可。
为实现本发明另一目的，本发明提供了显影盒，包括上述任一项所述的驱动组件。。
在其中一个实施例中，显影盒还包括感光鼓，驱动组件设置在所述感光鼓的端部，其中导杆与感光鼓同轴。
在其中一个实施例中，显影盒还包括显影辊，驱动组件设置在所述显影辊的端部，导杆与显影辊同轴。

具体实施方式
以下结合附图及实施例对本发明作进一步说明。
如图1所示，显影盒100包括盒体101和驱动组件10，驱动组件10设置在盒体101纵向的一端部，以与电子照相成像设备的驱动轴200接合以传递驱动力至显影盒100内的处理构件，驱动轴200(即驱动头)的端部具有径向突起201。显影盒内可具有感光鼓、显影辊、送粉辊等构件，驱动组件可设置在感光鼓或显影辊端部并与其同轴，从而接收驱动力直接带动感光鼓或显影辊旋转，也可设置为与任一构件都不同轴，但其轴与感光鼓、显影辊的轴平行设置，驱动组件接收驱动力后再通过齿轮组带动其他构件转动。本发明显影盒实施例中，除驱动组件与现有技术中的显影盒不同外，其他结构基本相同，因此以下将针对驱动组件的实施例对本发明进一步进行描述，本发明显影盒实施例中可具有任一驱动组件实施例中的驱动组件。
参见图2、图3、图4和图5，驱动组件10包括同轴设置的圆筒件1和联接件2，联接件2的连接端设置在圆筒件1内，自由端自圆筒件1内轴向向外伸出。圆筒件1的固定端与 其同轴地固定至显影盒的感光鼓端部或显影辊端部，也可固定至显影盒的其他结构上，圆筒件1的中间位置的外壁上设置有齿轮以与其他构件的齿轮啮合，以将驱动组件接收的驱动力传递至其他构件，圆筒件1的自由端设置有开口，联接件2从开口内轴向向外突出，且开口处设置有限位盖12，联接件2设置有限位突起35，限位盖12和限位突起35可以防止联接件2从圆筒件1内脱出，限位盖12及限位突起35为第一限位结构的实施例之一，可以理解的是，第一限位结构还可以其他方式设置。弹簧31作为作用力装置的一种实施例对联接件2施加轴向向外的作用力，在其他实施例中，作用力装置可设置为磁性装置、非金属弹性材料等。
联接件2包括同轴设置的导杆22和套筒3，其中导杆22可相对套筒3沿轴向往复移动，套筒3或导杆22上设置有限制导杆22相对套筒3轴向移动的第二限位结构，以防止导杆22从套筒内脱出。导杆22设置在套筒3内，且具有位于套筒3内的第一端和从套筒内露出的第二端，第二端设置有枢轴24，两个接合爪21可绕枢轴24转动地安装(即铰接)在导杆22的第二端，枢轴24与导杆22的轴线垂直，即接合爪21可在一包含导杆22的轴线的平面内转动，其自由端沿轴向向外突出。在导杆22的第二端接合爪21相对导杆22的轴线的偏转角度变大时，接合爪21轴向向外突出的距离变小。举例说明，相对于导杆22的第二端，接合爪21相对导杆22轴线的偏转角度可由接合爪21相对一平面所形成的锐角角度α来界定，该平面与导杆22的轴线平行或包含该轴线且与接合爪21转动时形成的面垂直，或者说该平面包含接合爪21的枢轴且与导杆22的轴线平行或包含该轴线。套筒3的连接端设置有使套筒连接端封闭的端头33，套筒3的自由端(即远离显影盒的端部)设置有径向向外突出的突出部分32，突出部分32上设置有开口向外的限位槽34。导杆22的第一端设置有径向外突的端头25，导杆22外套有弹簧23，弹簧23的一端与端头25抵接，另一端与套筒3的内壁抵接，弹簧23为偏压装置的一种实施方式，以向导杆22施加轴向向内的偏压力。接合爪21部分地容纳在限位槽34内，突出部分32一定程度上也可以限制接合爪21的最大偏转角度，进而限制接合爪21的轴向突出距离。弹簧23和突出部分32为第二限位结构的一种实施方式。
当显影盒安装至电子照相成像设备时，联接件2在弹簧31的作用下向外伸出至最大距离，导杆22在弹簧23的作用下轴向向内至最大距离，在联接件2与驱动轴200端部的弧形突起抵接时，在弧形突起202的推动下联接件2克服弹簧31的作用力向圆筒件1内移动，至导杆22的端部与弧形突起202相对时，联接件2在弹簧31的作用下向外移动。弧形突起202挤压导杆22，接合爪21更贴近驱动轴200，在驱动轴200转动时，接合爪21与驱动轴200的径向突起201接合，接合爪21的侧面与限位槽34的侧面抵接并接触，带动导杆22及套筒3转动，进而驱动组件转动。本实施例中，在旋转方向上，抵接面S位于旋转方向的下游，参见图6。在实际应用时，接触可为点接触、线接触或面接接触，在本实施例中为面接触，使驱动力的传递更为稳固。
图7a至图7c示出了在驱动组件从电子照相成像设备内拆卸时，驱动组件相对驱动轴的运动。在显影盒处于工作位置时，由于弧形突起202挤压导杆22，而套筒3在弹簧31的作用下轴向向外，即导杆22相对套筒3轴向向内移动距离最大，突出部分32使接合爪的偏转角度最小，并使接合爪21压向驱动轴200，以稳定地传递驱动力。当显影盒沿A向从电子照相成像设备内取出时，驱动轴200的弧形突起202推动接合爪21沿方向C转动，拉动导杆克服弹簧23的偏压力轴向向外移动，接合爪21的偏转角度变大，接合爪21的轴向突出距离变小，当套筒3的轴向移动不受阻时，联接件2克服弹簧31的作用力沿轴向向圆筒件1内移动，同时接合爪21沿方向C径向向外摆动，从而沿联接件2轴向突出的距离变小，与驱动轴200的径向突起201在径向上脱离，联接件2的自由端沿弧形突起202以A向移动，进而与驱动轴200脱离接合，然后导杆22在弹簧23的作用下轴向向内移动，突出部分32使接合爪向内偏转，并沿D向恢复至其初始位置，联接件2也在弹簧31的作用下向外推出。显影盒可从电子照相成像设备内取出。当联接件2的轴向移动受阻时，依靠接合爪21的偏转而减小轴向突出距离，也可使联接件2沿驱动轴200的弧形突起202移动而使显影盒从电子照相成像设备内拆卸下来。
图8a至图8d示出了驱动组件的偏压装置的几种实施例。如图8a所示，偏压装置为一拉簧，一端与套筒底部连接，另一端与导杆端部连接，以向导杆施加轴向向内的偏压力。图8b中的偏压装置由非金属弹性材料制成，可向导杆施加轴向向内或轴向向外的偏压力。图8c中的偏压装置122可为气体或液体密封装置，可向导杆施加轴向向内或轴向向外的偏压力。图8d中的偏压装置为磁性装置，其中，偏置装置可为上述实施方式中的一种或几种。可以理解的是，磁性装置的位置也可有所改动，只要能稳定施加偏压力即可。在偏压装置向导杆施加向内的偏压力时，接合爪受套筒的限制位于偏转角度小的较为闭合的位置，从而在初始位置时，接合爪的轴向突出距离较大。在偏压装置向导杆施加向外的偏压力时，接合爪位于偏转角度大的较为开放的位置，在驱动组件与驱动轴接合时，驱动轴推动导杆轴向向内移动，接合爪向轴线偏转，进而贴紧驱动轴并稳定传递驱动力。
在其他实施例中，接合爪可只有一个，通过枢轴或铰链铰接在导杆的第二端，在设置为多个时，优选的相对导杆对称地设置。在其他实施例中，偏压装置也可为弹片等的金属弹性结构。
