具体实施方式
下面将结合附图对本发明的实施例进行详细描述。为便于理解,除了驱动力接收件,背景技术所述专利申请中提及的处理盒及其各部件的编号和结构将在下文中直接引用。
可以理解的是,背景技术所述专利申请中所述的第一旋转件11和/或第二旋转件21既可以被驱动力接收件X4直接驱动,也可以被间接驱动;处理盒C既可以同时包括第一单元100和第二单元200,也可以仅包括第一单元100和第二单元200中的任何一个,显影剂被容纳在第一单元壳体1中设置有驱动力接收件X4的一侧被称为驱动端C1,与之相对的另一端被称为非驱动端C2,驱动端盖/第一端盖300安装在驱动端C1,驱动力接收件X4从驱动端C1暴露,非驱动端盖/第二端盖400安装在非驱动端C2,所述第一单元100和第二单元200可通过第一端盖300和第二端盖400相互结合,也可通过诸如销钉、卡扣等方式结合,第一端盖300、第二端盖400既可以作为第一单元100或第二单元200的一部分,也可以作为独立于第一单元100或第二单元200的部件,只要能够将第一单元100和第二单元200结合起来即可,第一端盖300与第一单元壳体1和第二单元壳体2结合,第二端盖400也与第一单元壳体1和第二单元壳体2结合;第一旋转件11可以是可旋转地设置在第一单元壳体1中的显影辊,第二旋转件21可以是可旋转地设置在第二单元壳体2中的感光鼓,然而,第一旋转件11和第二旋转件21还可以是处理盒中其他需要旋转的部件,例如,用于为感光鼓充电的充电件24,用于为显影辊供应显影剂的供应件102,用于搅拌显影剂的搅 拌件等,只要该驱动力接收件X4能够从成像设备中设置的力输出件接收驱动力并驱动旋转件旋转即可,也就是说,可旋转地安装在处理盒C中的感光鼓21、充电件24、显影辊11、供应件102、搅拌件等均可被称为旋转件,驱动力接收件X4通过从设备接收驱动力以驱动旋转件旋转,因而,所述旋转件和驱动力接收件X4的结合体可被统称为旋转组件。
处理盒C工作时,感光鼓21与显影辊11接触,显影辊11将显影剂供应至感光鼓21,下文中,驱动力接收件以数字4表示,所述驱动力接收件4被固定安装在旋转件的一个纵向末端,因而,驱动力接收件4与旋转件具有相同的旋转轴线。
图3A和图3B是本发明涉及的处理盒的立体图。
为使得下文描述方便,在此定义,处理盒C中安装有感光鼓21和显影辊11的一侧指向未安装感光鼓21和显影辊11的一侧为上方,与上方相对的一侧为下方,由第一单元100指向第二单元200的方向为前方,与前方相对的一侧为后方,接收驱动力的一侧为左方,与左方相对的一侧为右方,处理盒C沿上下方向从上向下被安装至设备,左方即为驱动端C1,右方即为非驱动端C2,第一端盖300被安装在驱动端C1,第二端盖400被安装在非驱动端C2,用于为显影辊11接收驱动力的第一驱动力接收件3(又可被称为“显影驱动力接收件3”)以及用于为感光鼓21接收驱动力的驱动力接收件4均从第一端盖300暴露。
下文中,以驱动力接收件4被直接安装在感光鼓21的末端为例进行描述。
【成像设备中的力输出件】
为使得下文的描述更清楚,在此有必要结合背景技术所述专利申请(引用专利申请)的附图对力输出件203做进一步描述。
图2A是现有力输出件的立体图;图2B是现有力输出件的局部立体图;图2C是现有力输出件中的制动力输出件被隐藏后的局部立体图;图2D是沿现有力输出件的旋转轴线观察时的俯视图。
如本专利申请图2A-图2D所示,驱动力输出件180包括圆柱形部分180c以及分别位于圆柱形部分180c两端的凸缘部分180a和驱动部180h,制动力输出件包括相互结合的第一制动接合构件204和第二制动结合构件208。如引用专利申请图48和本专利申请图32和图34B所示,驱动力输出件180和制动力输出件可绕旋转轴线M1沿旋转方向r同向旋转,且制动力输出件可随着驱动力输出件180一起旋转,在处理盒C安装至设备前,驱动力输出件180和制动力输出件部分重叠。
驱动力输出件180包括沿力输出件的径向方向相对布置的第一驱动力输出部180h和第二驱动力输出部180m,制动力输出件包括沿力输出件的径向方向相对布置的第一制动力输出部203a和第二制动力输出部203b,如图2D所示,沿旋转方向,第一驱动力输出部180h、第一制动力输出部203a、第二驱动力输出部180m和第二制动力输出部203b依次布置。
如图2D所示,经过旋转轴线M1、并经过第一制动力输出部203a和第二驱动力输出部180m之间以及 经过第一驱动力输出部180h和第二制动力输出部203b之间做一条分割线x,在图2D中,所述分割线x将力输出件203分隔为第一力输出部2031和第二力输出部2032,其中,第一力输出部2031包括第一驱动力输出部180h和第一制动力输出部203a,第二力输出部2032包括第二驱动力输出部180m和第二制动力输出部203b。所述第一驱动力输出部180h和第二驱动力输出部180m的结构相同,第一制动力输出部203a和第二制动力输出部203b的结构相同,驱动力接收件4与第一力输出部2031、第二力输出部2032的结合过程相同。
为便于描述,下文以第一力输出部2031与驱动力接收件4的结合过程为例进行描述;进一步的,第一力输出部2031中的第一驱动力输出部180h被简称为驱动力输出部/驱动部180h,第一力输出部2031中的第一制动力输出部203a被简称为制动部203a,沿旋转方向r,制动部203a位于驱动部180h的下游,驱动部180h和制动部203a可绕旋转轴线M1同向旋转,且制动部203a可随着驱动部180h一起旋转,在处理盒被安装至设备前,驱动部180h和制动部203a部分重叠。
制动部203a包括第一制动接合构件204和第二制动结合构件208,沿力输出件203的径向方向,第一制动结合构件204位于第二制动结合构件208的外侧,如引用专利申请图43所示,第一制动结合构件204和第二制动结合构件208通过旋转止动凹部204c和旋转止动突起部208c结合,因而,第一制动结合构件204和第二制动结合构件208可共同绕轴线M1旋转。
进一步的,力输出件203还包括第一弹簧(鼓驱动联轴器弹簧)210和第二弹簧(制动结合弹簧)211,第一弹簧210抵接制动传递构件207,制动传递构件207的凸缘部分207a与第二制动结合构件208抵接,同时,制动传递构件207的突起部207f还与驱动力输出件的接触表面180f(如引用专利申请图44)抵接;第二弹簧211抵接第一制动结合构件204的凸缘部分204a。沿轴线M1,第一制动结合构件204、第二制动结合构件208和驱动部180h被设置为均可沿轴线M1缩进和伸出,即沿所述引用专利申请图48的M1A和M1B所示方向运动,其中,第一制动结构件204和第二制动结合构件208既可以同时沿轴线M1缩进和伸出,在一些成像设备中二者也可以分别沿轴线M1缩进和伸出;当第二制动结合构件208沿轴线M1向着M1A所示方向(靠近凸缘部分180a/成像设备内部的方向)运动时,通过旋转止动凹部204c和旋转止动突起部208c,第一制动结合构件204也将沿轴线M1向着M1A所示方向运动,第一制动结合构件的凸起部204e与制动传递构件的凸起部207e沿旋转轴线L21脱离,最后,第一制动结合构件204和第二制动结合构件208均可绕轴线M1自由旋转,制动力不能通过制动力传递构件207被传递至第一制动结合构件204,第一制动结合构件204和第二制动结合构件208均不再输出制动力;同样的,当第一制动结合构件204沿轴线M1向着M1A所示方向运动时,通过第一制动结合构件204和第二制动结合构件208之间在旋转轴线L21方向上的结合机构,第一制动结合构件204也与制动传递构件的凸起部207e沿旋转轴线L21脱离,制动力也不能通过制动力传递构件207被传递至第一制动结合构件204,第一制动结合构件204和第二制动结合构 件208均不再输出制动力,因而,第一制动结合构件204和第二制动结合构件208至少之一沿轴线M1向着M1A所示方向运动时,均可达到屏蔽制动部203a的目的,此时,力输出件203将不再输出制动力。
进一步的,如所述引用专利申请图47和本专利申请图2D所示,第二制动结合构件208还具有从联轴器结合部分208b径向向内突出的内突起部208e,沿与M1A所示方向相反的M1B(如引用专利申请图48所示)所示方向,内突起部208e位于第二制动结合构件208的自由端处。如图2A-图2D所示,驱动力输出面180d位于驱动部180h上,沿力输出件203的旋转方向,驱动部180h与第一制动结合构件204相对,也就是说,以旋转轴线M1经过的点为圆心,在与旋转轴线M1垂直的平面中做一个圆,该圆将同时经过驱动部180h的至少一部分和第一制动结合构件204的至少一部分。
继续参考图2A-2D,所述第二制动结合构件208具有向着旋转轴线M1突出的内突起部208e,进一步的,沿力输出件203的旋转方向r,第一制动结合构件204具有位于第一制动结合构件主体204z下游的外输出面204g,第二制动结合构件208具有位于第二制动结合构件主体208z下游的内输出面208f,内突起部208e从第二制动结合构件主体208z径向向内/向着旋转轴线M1突出,沿旋转方向r,内突起部208e具有位于下游的平面208g,所述平面208g与内输出面208f相邻;进一步的,如图2B所示,沿旋转轴线M1,驱动部180h具有位于末端的驱动末端面180y,第一制动结合构件204具有位于末端的第一制动末端面204y,第二制动结合构件208具有位于末端的第二制动末端面208y,所述末端是指驱动部180h、第一制动结合构件204和第二制动结合构件208最远离凸缘部分180a的一端。
当驱动部180h与制动部203a相互靠近时,驱动部180h与制动部203a并不会相互紧贴,如图2D所示,沿旋转方向r,第一制动末端面204y与驱动部180h之间形成有间隙,该间隙的最小值为s,即第一制动末端面204y与驱动部180h之间最近的距离为s。
如图2C所示,驱动部180h设置为沿驱动力输出件180的径向相对布置的两个,驱动力输出件180还包括连接两个驱动部的连接件180k,所述连接件180k包括中间件183以及分别位于中间板183径向两侧的第一连接件181和第二连接件182,下述定位凸台180i从中间板183沿旋转轴线M1突出,所述第一连接件181和第二连接件182的结构相同,并分别与一个驱动部连接。
进一步的,驱动部180h面向第一制动结合构件204的一侧表面(驱动力输出面)180d设置有下突出部180g,沿旋转方向r,驱动部180h还设置有与驱动力输出面180d相邻的倾斜面180j,第一制动结合构件204面向驱动部180h的一侧表面设置有上突出部204f,在处理盒100被安装前,驱动部180h与第一制动结合构件204沿旋转方向r相互靠近,沿旋转轴线M1,上突出部204f和下突出部180g相对/重叠。
整体上看,下突出部180g与第一连接件181一体形成,驱动力输出面180d从下突出部180g沿旋转轴线M1突出,沿旋转方向r,下突出部180g还可以被视为从第一连接件181/驱动力输出面180d突出,所述下突出部180g的末端形成为可跟随驱动部180h旋转的前表面180g1;进一步的,沿旋转方向r,第 一连接件181还具有位于旋转方向下游的子前表面180g2,所述前表面180g1与子前表面180g2连接,且前表面180g1和子前表面180g2均位于第一连接件181的下游末端,因而,前表面180g1和子前表面180g2可被合称为第一连接件181的下游末端面。
沿旋转方向r,力输出件203具有第一空间K1、第二空间K2和第三空间K3,其中,第一空间K1是指前表面180g1和制动部203a之间的空间,第二空间K2是指制动部203a与位于该制动部下游的驱动部180h之间的空间,具体的,如图2D所示,第二空间K2是指第一制动力输出部203a和第二驱动力输出部180m之间的空间,或第二制动力输出部203b和第一驱动力输出部180h之间的空间,第三空间K3是指驱动部180h/驱动力输出面180d与第一制动结合构件204之间的空间;当驱动部180h和制动部203a部分重叠时,如图2D所示,沿旋转方向r,第二空间K2大于第一空间K1/第三空间K3。
如图4A所示,本发明涉及的驱动力接收件4具有旋转轴线L21,包括连接部41、底盘42、基座43和结合部44,沿旋转轴线L21,连接部41、底盘42、基座43和结合部44依次排列,连接部41与旋转件直接或间接结合,用于将驱动力传递至旋转件,以驱动旋转件旋转,底盘42与旋转件抵接,使得驱动力接收件4相对于旋转件定位,基座43从底盘42延伸,且基座43和连接部41分别位于底盘42的两侧,结合部44从基座43向远离底盘42的方向延伸;作为简化结构的,底盘42可被省略,基座43直接从连接部41延伸,更简化的,基座43也可被省略,结合部44从连接部41延伸。
下文将对结合部44的结构进行描述,驱动力接收件4的其他结构在此不做限制。为更清楚的展示本发明涉及的驱动力接收件的结构,下文均只示出了驱动力接收件4,然而应当理解的是,驱动力接收件4可适用于处理盒中的各个旋转件。
【驱动力接收件】
[实施例一]
图4A是本发明实施例一涉及的驱动力接收件的感光鼓立体图;图4B是本发明实施例一涉及的第一种驱动力接收件的立体图;图4C是本发明实施例一涉及的第一种驱动力接收件沿其旋转轴线观察时的侧视图。
感光鼓21具有旋转轴线L21,驱动力接收件4包括连接部41(如图4B所示)、底盘42、基座43和结合部44,连接部41通过嵌入感光鼓21内部的方式实现驱动力接收件4与感光鼓21的连接,底盘42与感光鼓21抵接,使得驱动力接收件4相对于感光鼓21定位,基座43从底盘42延伸,结合部44从基座43向远离底盘42的方向延伸;作为简化结构的,底盘42可被省略,基座43直接从连接部41延伸,更简化的,基座43也可被省略,结合部44从连接部41延伸,只要结合部44接收到的驱动力能够驱动感光鼓21旋转即可。
下文将对结合部44的结构进行描述,驱动力接收件4的其他结构在此不做限制。
结合部44包括中心柱45以及从中心柱45径向向外延伸的驱动力接收部46,旋转轴线L21穿过中心柱45,优选的,两个驱动力接收部46径向相对设置在中心柱45的外围,可理解的,在中心柱45的径向外侧仅设置一个驱动力接收部46也能够达到从力输出件203接收驱动力并驱动感光鼓21旋转的目的。如图4A和图4B所示,每个驱动力接收部46包括与中心柱45连接的基部461以及位于基部461径向外侧的凸块462,沿驱动力接收件4的径向方向,凸块462位于基部461的径向外侧,导引面463从基部461向着凸块462延伸,凸块462具有与导引面463相邻的第一表面/驱动面464和第二表面/制动面465,且第一表面464和第二表面465均与旋转轴线L21平行。
随着处理盒C向着设备安装,导引面463导引制动部203a相对于驱动部180h移动,使得驱动力接收部46到达驱动部180h和制动部203a之间,即驱动力接收部46进入第三空间K3,如图4C所示,驱动力输出面180d与第一表面464抵接,第二表面465与制动部203a相互间隔,当驱动部180h沿旋转方向r转动时,驱动力通过第一表面464被传递至结合部44,进而,感光鼓21被驱动而绕旋转轴线L21转动。
由于第二表面465与制动部203a相互间隔,也就是说,驱动力接收件4停止工作时不再需要被制动,处理盒C从工作状态回到不工作状态的过程中或感光鼓21从旋转状态回到不旋转状态的过程中,沿感光鼓21的圆周方向,制动部203a不向驱动力接收件4施加作用力/制动力,相当于制动部203a被屏蔽,有利于减小驱动力接收件4工作时的磨损,所述工作状态是指处理盒C/成像设备进行显影操作,所述不工作状态是指处理盒C/成像设备不进行显影操作。进一步的,采用了本实施例涉及的驱动力接收件4后,设备中的制动部203a不再需要回到与驱动部180h相互靠近或部分重叠的位置,有利于简化设备的结构,对于已经处于分离状态的驱动部180h和制动部203a来说,下一个处理盒的驱动力接收件4可不必设置导引面463,处理盒C的结构也可被简化。
[实施例二]
图5A是本发明实施例二涉及的驱动力接收件的立体图;图5B是本发明实施例二涉及的驱动力接收件沿其旋转轴线观察时的侧视图。
为便于理解,与上述第一种驱动力接收件4相同的结构将采用相同的编号。本实施例中的驱动力接收部46的结构与实施例一不同。如图所示,本实施例中的驱动力接收部46形成为至少一对相互间隔的凸块46a和凸块46b,所述凸块46a和凸块46b从中心柱45向着远离旋转轴线L21的方向延伸,二者之间形成驱动空间46c,每个凸块均具有相对的第一表面464和第二表面465,如图5B所示,凸块46a的第二表面465与凸块46b的第一表面464形成为驱动空间46c的边缘,当处理盒C被安装时,驱动部180h进入驱动空间46c,制动部203a位于驱动空间46c的外部,或者说,第二凸块46b进入第三空间K3,当处理盒C工作时,驱动部180h与凸块46b的第一表面464抵接,制动部203a远离凸块46b的第二表面465,驱动力接收件4在驱动部180h的驱动作用下绕旋转轴线L21沿r所示方向旋转。
与实施例一不同的,本实施例涉及的驱动力接收件4具有被制动功能,具体为,当驱动部180h停止向凸块第一表面464施加驱动力时,感光鼓21/驱动力接收件4可能会在惯性作用下继续沿r所示方向转动,此时,凸块46a的第二表面465将与驱动部180h抵接,由于驱动部180h已停止转动,驱动力接收件4在驱动部180h的制动作用下被制动,也就是说,处理盒C从工作状态回到不工作状态的过程中或感光鼓21从旋转状态回到不旋转状态的过程中,沿感光鼓21的圆周方向,制动部203a不向驱动力接收件施加作用力/制动力,相当于制动部203a被屏蔽,驱动力接收件4的制动由驱动部180h与凸块46a的抵接完成。
同样的,采用了本实施例涉及的驱动力接收件4后,设备中的制动部203a不再需要回到与驱动部180h相互靠近或部分重叠的位置,有利于简化设备的结构,对于已经处于分离状态的驱动部180h和制动部203a来说,下一个处理盒的驱动力接收件4可不必设置导引面463,处理盒C的结构也可被简化。
其中,为便于区分,凸块46a可被称为第一凸块,凸块46b可被称为第二凸块,沿感光鼓21/驱动力接收件4的旋转方向r,第一凸块46a位于第二凸块46b的上游;可理解的,如图5B所示,当处理盒C在设备中工作时,第一凸块的第二表面465与驱动部180h之间的最小距离小于第二凸块的第二表面465与制动部203a之间的最小距离,以确保驱动力接收件4在被制动的过程中,第一凸块46a与驱动部180h抵接,而第二凸块46b不会与制动部203a抵接。
[实施例三]
图6A是本发明实施例三涉及的驱动力接收件的立体图;图6B是本发明实施例三涉及的驱动力接收件沿其旋转轴线观察时的侧视图。
为便于理解,与上述第一种驱动力接收件4相同的结构将采用相同的编号。
本实施例中的驱动力接收部46的结构与实施例一不同。如图6A所示,本实施例中,驱动力接收部46被简化为至少一个独立的凸块462,所述凸块462也具有相对的第一表面464和第二表面465,沿旋转方向r,第一表面464位于第二表面465的上游,当处理盒C被安装至设备预定位置时,第一表面464到达制动部203a的下游空间K2(第二空间K2),此时,第一表面464与制动部203a相对。
当处理盒C开始工作时,制动部203a随着驱动部180h一起旋转,此时,制动部203a与第一表面464抵接,并驱动所述驱动力接收件4沿旋转方向r转动,同实施例一的,本实施例中的驱动力接收件4在停止工作时也不需要被制动部制动,有利于减小驱动力接收件4工作时的磨损;处理盒C从工作状态回到不工作状态的过程中或感光鼓21从旋转状态回到不旋转状态的过程中,沿感光鼓21的圆周方向,驱动部180h不向驱动力接收件施加作用力/制动力,相当于驱动部180h被屏蔽。
本实施例中的驱动力接收件4的结构被简化,同时驱动力接收部46与力输出件203的接触面增大,提升了驱动力接收部46和力输出件203的结合稳定性和驱动力接收部46的受力稳定性,驱动力接收部46和力输出件203不易脱离。
另一方面,由于第二空间K2最大,相比于驱动力接收部46进入第一空间K1或第三空间K3,所述驱动力接收部46更容易进入第二空间K2,因而,采用制动部203a驱动所述驱动力接收件4的方案还可提高驱动力接收件4与力输出件203的结合效率,防止驱动力接收件4与力输出件203的结合错位。
[实施例四]
图7是本发明实施例四涉及的驱动力接收件的立体图;图8A和图8B是本发明实施例四涉及的驱动力接收件与设备中的驱动部、制动部结合前后的状态示意图;图9是本发明实施例四涉及的驱动力接收件与设备中的驱动部、制动部结合后,沿该驱动力接收件的旋转轴线垂直的平面剖切的剖视图。
本实施例中,驱动力接收件4仍然包括连接部41、底盘42、基座43和结合部44,连接部41与感光鼓连接,底盘42与感光鼓抵接,驱动力接收件4被固定在感光鼓21上,基座43从底盘42延伸,结合部44从基座43向远离底盘42的方向延伸;同实施例一的,底盘42和基座43至少之一可被省略。结合部44包括中心柱45以及从中心柱45径向向外延伸的驱动力接收部46,旋转轴线L21穿过中心柱45,两个驱动力接收部46径向相对的设置在中心柱45的外围,在设置有基座43的情况下,优选的,驱动力接收部46与基座43一体形成,沿驱动力接收件4的圆周方向,两个驱动力接收部46之间形成两个驱动空间46c,每个驱动空间46c能够同时容纳设备中的力输出件203的一部分,第一力输出部2031的至少一部分进入其中一个驱动空间46c,第二力输出部2032的至少一部分进入另一个驱动空间46c。
如图8A所示,安装有驱动力接收件4的感光鼓21随着处理盒C被安装,在处理盒C向着设备安装的过程中,如果驱动部180h和制动部203a正好与驱动空间46c相对,那么驱动部180h和制动部203a将直接进入驱动空间46c,如果驱动部180h和制动部203a不能完全与驱动空间46c相对,随着驱动部180h/制动部203a的旋转,驱动部180h和制动部203a最终可进入驱动空间46c中。
沿旋转方向r,制动部203a向驱动力接收部46输出驱动力,进而驱动所述驱动力接收件4旋转,同实施例二的,当制动部203a停止向驱动力接收部46传递驱动力时,驱动部180h将对继续旋转的驱动力接收件4进行制动,也就是说,当处理盒C采用本实施例涉及的驱动力接收件4时,设备中的驱动部180h和制动部203a的功能将相互对调,即在处理盒C的工作过程中,设备中的制动部203a起驱动作用,在处理盒C需要回到不工作状态时或感光鼓21从旋转状态回到不旋转状态的过程中,设备中的驱动部180h起制动作用,因而,驱动力接收件的结构和设备的结构均得到简化,且驱动力接收部46也能够容易的进入第二空间K2。
[实施例五]
图10A和图10B是本发明实施例五涉及的驱动力接收件与设备中的驱动部、制动部结合前后的状态示意图。
本实施例中,设备中的驱动部180h和制动部203a至少之一被设置成可沿旋转轴线M1伸缩,驱动力 接收件4的两个驱动力接收部46之间仍然具有驱动空间46c,当驱动力接收件4随着处理盒C被安装时,驱动力接收件4的末端面4w将与驱动部180h和制动部203a至少之一抵接,因而,驱动部180h和制动部203a至少之一被压迫而向着设备内缩回。
如图10B所示,当驱动部180h或制动部203a进入驱动空间46c时,所述驱动部180h或制动部203a将随着设备的启动而驱动所述驱动力接收件4绕旋转轴线L21沿r所示方向转动;当驱动部180h和制动部203a同时被压迫时,随着设备的启动,驱动部180h和制动部203a同时开始旋转,但驱动力接收件4不被驱动,直至驱动部180h和制动部203a之一进入驱动空间46c。
本实施例中的驱动力接收件4可被驱动部180h或制动部203a驱动,当驱动力接收件4被驱动部180h驱动时,制动部203a被所述末端面4w压迫而缩回,相当于制动部203a被屏蔽,在处理盒C处于工作状态时,以及处理盒C从工作状态回到不工作状态的过程中,制动部203a不再起作用,沿感光鼓21的圆周方向,制动部203a不再向驱动力接收件传递作用力/制动力;当驱动力接收件4被制动部203a驱动时,驱动部180h被所述末端面4w压迫而缩回,相当于驱动部180h被屏蔽,在处理盒C处于工作状态时,以及处理盒C从工作状态回到不工作状态的过程中或感光鼓21从旋转状态回到不旋转状态的过程中,沿感光鼓21的圆周方向,驱动部180h不再向驱动力接收件4传递作用力/驱动力,即驱动部180h不再起作用;同样的,驱动力接收件4的结构和设备的结构均得到简化。
由上述实施例可知,驱动部180h或制动部203a均可向驱动力接收件4传递驱动力,当采用驱动部180h向驱动力接收件4传递驱动力的方式时,在处理盒从工作状态回到不工作状态的过程中或感光鼓21从旋转状态回到不旋转状态的过程中,沿感光鼓21的圆周方向,制动部203a不向驱动力接收件传递作用力/制动力,此时,制动部203a被屏蔽,具体而言,所述被屏蔽的方式可以是沿旋转方向r,使得制动部203a远离驱动力接收件4中的驱动力接收部46,还可以是沿旋转轴线L21,利用驱动力接收件4的末端面4w将制动部203a压迫至缩回状态,同样的,所述屏蔽方式也适用于驱动部180h。
为便于理解,下述实施例的各部件与前述实施例相同功能的部件将使用相同的名称和编号。
[实施例六]
图11A是本发明实施例六涉及的驱动力接收件的立体图;图11B是沿与本发明实施例六涉及的驱动力接收件的旋转轴线垂直的方向观察驱动力接收件的侧视图;图11C是沿本发明实施例六涉及的驱动力接收件的旋转轴线观察该驱动力接收件的侧视图。
结合部44包括中心柱45以及沿着中心柱45/驱动力接收件4的径向向外延伸的驱动力接收部46,优选的,驱动力接收部44从中心柱45向外延伸,旋转轴线L21穿过中心柱45,驱动力接收部46既可以设置为沿中心柱45圆周方向布置的一个,也可以是多个;进一步的,驱动力接收部46还可以被视为沿旋转轴线L21从基座43延伸形成。
以其中一个驱动力接收部46为例,所述驱动力接收部46包括与中心柱45连接的基部461以及设置在基部461的驱动面464、制动面465和接触面463,沿驱动力接收件4的旋转方向,驱动面464和制动面465相对布置,在驱动力接收件4随着处理盒C向着成像设备安装的过程中,接触面463与第一制动结合构件204的联轴器结合部分204b和第二制动结合构件208的联轴器结合部分208b至少之一抵接,使得驱动力接收部46到达驱动力输出面180d和驱动面464相对的位置,当力输出件203旋转时,驱动力接收件4/驱动力接收部46沿图11C中r所示方向旋转。
沿驱动力接收件4的旋转方向,基部461包括相邻的第一部分461a(即下述凸块462)和第二部分461b,其中,驱动面464和制动面465位于第一部分,接触面463在第一部分461a和第二部分461b同时延伸,沿驱动力接收件4的径向方向,第一部分461a比第二部分461b突出的更远,优选的,第一部分461a和第二部分461b一体形成。
本实施例中,接触面463形成为基部461的末端面,如图11B所示,当沿着与旋转轴线L21垂直的方向观察时,接触面463与旋转轴线L21相互垂直,具体的,沿驱动力接收件4的旋转方向,接触面463包括与第一部分461a对应的第一接触面463a以及与第二部分461b对应的第二接触面463b,所述第一接触面463a和第二接触面463b均与旋转轴线L21相互垂直,这样,驱动力接收部46的结构可被简化,有利于提升该驱动力接收部46和包括该驱动力接收部46的驱动力接收件4的生产效率。
当具有该驱动力接收件4的处理盒C安装时,接触面463与制动部203a(第一制动结合构件204和第二制动结合构件208)的末端抵接,随着处理盒C的继续安装,制动部203a被向着成像设备内部压缩,第一制动结合构件204与背景技术所述专利申请中的制动传递构件207脱离结合,沿旋转方向r,驱动面464到达与驱动力输出面180d相对的位置,制动面465不与制动部203a相对,在处理盒C停止工作时,驱动力输出面180d不再向驱动面464输出驱动力,本实施例中,接触面463起着将制动部203a向着成像设备内部压迫进而引导驱动力接收件4与力输出件203相互结合的作用,因而,接触面463也可被称为压迫面或导引面;在处理盒C的工作过程中,制动部203a既可以被设置成向制动面465施加制动力,也可以被设置成不向制动面465施加制动力。
当沿着与沿旋转轴线L21垂直的方向观察时,第一接触面463a和第二接触面463b可以对齐设置,也可以错位设置,当二者错位设置时,第一接触面463a和第二接触面463b之间将形成高度差,在处理盒C的安装过程中,第一接触面463a和第二接触面463b仍然将制动部203a向着成像设备内部压缩,但由于第一接触面463a和第二接触面463b仍被设置为与旋转轴线L21相互垂直的平面,相对于现有设置为螺旋状的导引面X463,该结构仍然有利于提升该驱动力接收部46以及包括该驱动力接收部46的驱动力接收件4的生产效率。
沿旋转轴线L21,当第二接触面463b比第一接触面463a更远离连接部41时,在驱动力接收件4与 力输出件203的结合过程中,制动部203a将先被第二接触面463b抵接而缩回,这样,沿旋转方向r,驱动面464将能够更顺利的到达与驱动部180h相对的位置。
优选的,当沿着与沿旋转轴线L21垂直的方向观察时,第一接触面463a和第二接触面463b对齐设置,更优选的,当沿着与沿旋转轴线L21垂直的方向观察时,第一接触面463a和第二接触面463b连为一体,也就是说,第一接触面463a和第二接触面463b共同构成驱动力接收部46的末端面,且该末端面与旋转轴线L21相互垂直,以处理盒壳体在非驱动端C2最远离驱动端C1的表面CP为准,当沿着旋转轴线L21的方向测量时,第一接触面463a到表面CP的距离为h1,第二接触面463b到表面CP的距离为h2,h1=h2,从而,驱动力接收部46的结构可被简化,有利于提升该驱动力接收部46以及包括该驱动力接收部46的驱动力接收件4的生产效率。
(变形结构一)
图12A是本发明实施例六涉及的驱动力接收件的一种变形结构的立体图;图12B是沿图12A所示驱动力接收件的旋转轴线观察该驱动力接收件的侧视图。
发明如图所示,所述第二部分461b被切除,第一部分461a被保留,驱动力接收部46的整体结构被进一步简化,同样的,沿旋转轴线L21,第一部分461a的末端面463a即为接触面,该接触面463a还与旋转轴线L21相互垂直;沿驱动力接收件4的径向方向,接触面463a、驱动面464和制动面465均延伸至基部461的末端,如图12B所示,沿驱动力接收件4的径向方向,接触面463a、制动面465和驱动面464在径向最外侧点分别为E、F、G,旋转轴线L21到点E、F、G的距离相等,因而,驱动力接收部46以及包括该驱动力接收部46的驱动力接收件4的生产效率可被提升。
(变形结构二)
图13A是本发明实施例六涉及的驱动力接收件的另一种变形结构的立体图;图13B是沿与图13A所示驱动力接收件的旋转轴线垂直的方向观察该驱动力接收件的侧视图。
发明与上述变形结构一类似的,第一部分461a的末端面463a被设置为不与旋转轴线L21相互垂直,而是设置为相对于旋转轴线L21倾斜的斜面或设置为沿驱动力接收件4的旋转方向延伸的螺旋面,且沿驱动力接收件4的径向方向,末端面463a、驱动面464和制动面465均延伸至基部461的末端,旋转轴线L21分别到接触面463a、制动面465和驱动面464在径向方向最外侧的点之间的距离相等,因而,驱动力接收部46以及包括该驱动力接收部46的驱动力接收件4的生产效率可被提升。
[实施例七]
图14A是本发明实施例七涉及的驱动力接收件的立体图;图14B是沿与本发明实施例七涉及的驱动力接收件的旋转轴线垂直的方向观察驱动力接收件的侧视图。
与背景技术不同的是,本实施例中的驱动力接收部46还包括设置在导引面463的突出部463c,如图 14B所示,当沿着旋转轴线L21的方向测量时,导引面463到驱动力接收件4的某一个固定面(例如,基座43、底盘42和连接部41之一与旋转轴线L21垂直的表面)或者到处理盒的某一个固定面(如上述表面CP)的距离将不再是一个固定值或渐变值,而是随着突出部463c的突起而在大小之间转换,所述固定面还可以被视为第一特定面,该第一特定面为不同于导引面463,且第一特定面还与旋转轴线L21垂直。
如图14B所示,以表面CP为参考面,沿旋转方向r,选取导引面463位于突出部463c上游的一个点B1、突出部463c上游与导引面463相交处的一个点B2以及突出部463c的最高点B3,所述点B1位于旋转方向r的最上游,点B3位于旋转方向r的最下游,沿旋转轴线L21测量,点B1到表面CP的距离为h3,点B2到表面CP的距离为h4,点B3到表面CP的距离为h5,h3>h5>h4;在处理盒C的安装过程中,该突出部463c与制动部203a抵接,可减小驱动力接收件4与制动部203a之间的摩擦力,使得驱动力接收部46能够更容易的与力输出件203结合,同时,该突出部463c还能够减缓制动面465与制动部203a中的联轴器结合部分204b/208b的结合速度,从而,驱动力接收件4与制动部203a结合过程中的噪音可被减小,还有利于防止制动部203a被损坏。
基于本实施例中结合部44的结构,突出部463c还可以被设置为,在突出部463c与制动部203a抵接后,制动部203a一直保持在被抵接的状态,此时,制动部203a向着成像设备内部缩回而不会与制动面465抵接,也就是说,力输出件203中仅驱动部180h向驱动力接收件4输出驱动力,制动部203a不再向驱动力接收件4输出制动力。
在处理盒C的安装过程中,当驱动部180h与制动部203a相互靠近的情况下,导引面463用于将驱动力输出面180d和制动部203a中的联轴器结合部分204b/208b相互分离,使得驱动力输出面180d与驱动力面464相对,联轴器结合部分204b/208b与制动面465相对;在处理盒C的工作过程中,驱动力输出面180d向驱动面464施加驱动力,在处理盒C停止工作时,驱动力输出面180d不再向驱动面464输出驱动力,联轴器结合部分204b/208b在驱动力接收部46旋转方向的下游侧向制动面465施加制动力,驱动力接收件4/驱动力接收部46停止旋转。
(变形结构)
图15A是本发明实施例七涉及的驱动力接收件的一种变形结构的立体图;图15B是沿与本发明实施例七涉及的驱动力接收件的旋转轴线垂直的方向观察驱动力接收部的侧视图。
该变形结构中,从导引面463突出的突出部463c被凹陷部463d代替,当沿着旋转轴线L21的方向测量时,导引面463c到驱动力接收件4的某一个固定面(例如,基座43、底盘42和连接部41之一与旋转轴线L21垂直的表面)或者到处理盒的某一个固定面(如上述表面CP)的距离将不再是一个固定值或渐变值,而是随着凹陷部463d的凹陷而在大小之间转换,如图15B所示,以表面CP为参考面,沿旋转方向r,选取导引面463位于凹陷部463d上游的一个点B1’、凹陷部463d的最低点B2’以及导引面463位于 凹陷部463d下游的一个点B3’,所述点B1’位于旋转方向r的最上游,点B3’位于旋转方向r的最下游,沿旋转轴线L21测量,点B1’到表面CP的距离为h3’,点B2’到表面CP的距离为h4’,点B3’到表面CP的距离为h5’,h3’>h5’>h4’。
同样的,凹陷部463d还可以被设置为,在凹陷部463d与制动部203a抵接后,制动部203a一直保持在被抵接的状态,此时,制动部203a向着成像设备内部缩回而不会与制动面465抵接,也就是说,力输出件203中仅驱动部180h向驱动力接收件4输出驱动力,制动部203a不再向驱动力接收件4输出制动力。
[实施例八]
图16A是本发明实施例八涉及的驱动力接收件的立体图;图16B是沿与图16A中旋转轴线垂直并经过制动面的平面剖切后的剖视图。
与背景技术不同的是,本实施例中的驱动力接收部46还包括位于驱动面464和制动面465至少之一径向外侧的凸缘部47,优选的,所述凸缘部47沿导引面463的径向外侧向外延伸,沿旋转轴线L21,凸缘部47的远离基座43/底盘42/连接部41的表面与导引面463共面,因而,导引面463的至少一部分还可以被视为位于驱动面464和制动面465至少之一的径向外侧。
具有本实施例所述驱动力接收部46/驱动力接收件4的处理盒C在向着成像设备的安装过程中,制动部203a中的联轴器结合部分204b/208b可通过与凸缘部47结合而更容易的到达与制动面465相对的位置。
[实施例九]
图17是本发明实施例九涉及的驱动力接收件的立体图。
本实施例中,上述制动面465被取消,如图所示,驱动力接收部46仅设置有驱动面464和导引面463,所述导引面463从基座43螺旋向上延伸,在具有该驱动力接收部46/驱动力接收件4的处理盒C被安装至成像设备后,导引面463还可与制动部203a的联轴器结合部分204b/208b相对而起到与制动面465相同的作用,因而,驱动力接收部46的结构被简化,有利于提升驱动力接收部46以及具有该驱动力接收部46的驱动力接收件4的生产效率。
进一步的,凸缘部47沿中心柱45的外圆周设置,或者说,凸缘部47从中心柱45的外圆周表面径向向外突出形成,优选的,沿旋转轴线L21,凸缘部47位于/靠近中心柱45的自由末端451(远离连接部41的一端),当沿着与旋转轴线L21垂直的方向观察时,驱动力接收部46与凸缘部47不重合,沿驱动力接收件4的径向方向,凸缘部47的突出尺寸不超过基部461/驱动面464/导引面463的尺寸,具有该结构的驱动力接收件4与力输出件203结合的过程中,制动部203a的联轴器结合部分204b/208b勾住凸缘部47而实现驱动力接收件4与力输出件203的结合,能够有效防止驱动力接收件4的驱动面464与力输出件203的驱动力输出面180d脱离结合,从而确保驱动力接收件4能够稳定的从力输出件接收驱动力。
(变形结构)
图18是本发明实施例九涉及的驱动力接收件的一种变形结构的立体图。
该变形结构中,沿旋转轴线L21,相对于中心柱45的自由末端451,凸缘部47向着靠近连接部41的位置(远离中心柱自由末端451的位置)设置,沿驱动力接收件4的径向方向,凸缘部47的突出尺寸不超过基部461/驱动面464/导引面463的尺寸。
如背景技术所述专利申请的图44所示,力输出件203除了具有上述驱动部180h和制动部203a,还具有位于驱动部180h中的定位柱(定位凸台)180i,当驱动力接收件4与力输出件结合时,如背景技术所述专利申请的图51所示,位于力输出件的定位柱180i进入中心柱45的定位孔452中,凸缘部47将随着驱动力接收部46逐渐靠近制动部203a,直至联轴器结合部分204b/208b勾住凸缘部47,因而,将凸缘部47向着靠近连接部41的位置设置将使得联轴器结合部分204b与凸缘部47能够结合的更紧密,能够更有效的防止驱动面464与驱动力输出面180d脱离结合,从而,驱动力接收件4能够更稳定的从力输出件接收驱动力。
[实施例十]
图19是本发明实施例十涉及的驱动力接收件的立体图;图20A是本发明实施例十涉及的驱动力接收件开始与力输出件结合的立体图;图20B是本发明实施例十涉及的驱动力接收件与力输出件结合后的立体图;图20C是本发明实施例十涉及的驱动力接收件与力输出件结合后,沿与驱动力接收件的旋转轴线垂直的方向观察的侧视图。
本实施例中的驱动力接收件4被设置成,结合部44的至少一部分可沿与旋转轴线L21相交的方向运动,如图所示,当沿着驱动力接收件的旋转轴线L21从结合部44向着连接部41的方向观察时,驱动力接收件4可绕旋转轴线L21沿r所示方向(顺时针方向)旋转,沿着所述旋转方向r,结合部44被分割为相互间隔的多个子结合部。
下文以设置有四个子结合部为例,沿旋转方向r,依次设置有第一子结合部4a、第二子结合部4b、第三子结合部4c和第四子结合部4d,其中,第一子结合部4a和第三子结合部4c径向相对,第二子结合部4b和第四子结合部4d径向相对,且第二子结合部4b和第四子结合部4d至少之一的一部分被设置为相对于第一子结合部4a和第三子结合部4c可活动,每个子结合部包括中心柱45的一部分;第一子结合部4a和第三子结合部4c又可被称为固定结合部,第二子结合部4b和第四子结合部4d又可被称为活动结合部,活动结合部相对于固定结合部可活动。
优选的,第一子结合部4a的结构和第三子结合部4c的结构相同,第二子结合部4b的结构和第四子结合部4d的结构相同;固定结合部和活动结合部均从连接部41/底盘42/基座43延伸形成,其中,活动结合部被设置为从连接部41/底盘42/基座43延伸形成的悬臂,例如,沿驱动力接收件4的径向方向,活 动结合部与连接部41/底盘42/基座43的连接处的尺寸小于固定结合部与连接部41/底盘42/基座43的连接处的尺寸;更优选的,固定结合部和活动结合部均从基座43远离连接部41的一侧延伸形成。
固定结合部包括基板450、基部461和凸块462,沿与旋转轴线L21垂直的径向方向,基板450、基部461和凸块462依次布置,并逐渐远离旋转轴线L21,基板450为中心柱45的一部分,基部461上设置有导引面463,凸块462上设置有驱动面464,沿旋转方向r,驱动面464位于导引面463的上游,沿旋转轴线L21,基部461还形成有抵接面466;活动结合部包括基板450、设置在基板450的凸缘部47和压迫部48,所述压迫部48从基板450向着远离旋转轴线L21的方向延伸,在远离连接部41的一端形成有压迫面481;本实施例中的凸缘部47也具有防止驱动力接收件4与力输出件203脱离结合的作用,因而,凸缘部47可被视为防脱部的一个实施例,具体的,本实施例中的凸缘部47设置为从基板450的自由末端(中心柱的自由末端)451径向向外突出形成。
优选的,当沿与旋转轴线L21垂直的方向观察时,抵接面466与压迫面481基本齐平,并与旋转轴线L21垂直,进一步的,沿旋转轴线L21,抵接面466和压迫面481均与中心柱的自由末端451分离,或者说,抵接面466和压迫面481均比中心柱的自由末端451更加靠近连接部41,压迫面481与中心柱的自由末端451之间形成限位空间482。
为更清楚的展示驱动力接收件4与力输出件203的结合过程,本实施例以及下述实施例中的力输出件203均被切除一部分,使得驱动部180h和制动部203a均暴露出来。
如图20A、图20B和图20C所示,当驱动力接收件4随着处理盒C沿旋转轴线L21逐渐靠近力输出件203时,导引面463开始与第二制动结合构件208的内突起部208e抵接,随着处理盒C的继续安装,第二制动结合构件208开始沿旋转方向r被导引面463引导,因而,第一制动结合构件204也将一起沿旋转方向r运动,即整个制动部203a一起沿旋转方向r逐渐远离驱动部180h,同时,沿旋转轴线L21,上突出部204f和下突出部180g不再相对而逐渐错开,整个制动部203a还向着圆柱形部分180c/成像设备的内部缩回(缩回状态),这样,驱动部180h不会被制动部203a带动而一起向着圆柱形部分180c的内部缩回。
沿旋转方向r,随着驱动部180h与制动部203a相互分离,凸块462进入驱动部180h与制动部203a之间,驱动力输出面180d与驱动面464相对;制动部203a(第二制动结合构件204)至少被抵接面466抵接而保持在缩回状态,驱动力接收件4与力输出件203完成结合,当驱动部180h开始旋转时,驱动力输出面180d向驱动面464输出驱动力,驱动力接收件4开始绕旋转轴线L21旋转。
需要说明的是,在驱动力接收件4与力输出件203结合的过程中,如果制动部203a(第二制动结合构件204)被导引面463导引后滑过抵接面466而到达与压迫面481相对的位置时,制动部203a(第二制动结合构件204)仍然能够保持在缩回状态,也就是说,压迫面481等同于抵接面466而具有防止制动部203a(第二制动结合构件204)从缩回状态伸出而回到初始状态(伸出状态)的作用。
本实施例中,将制动部203a保持在缩回状态,在处理盒工作过程中,制动部203a将不再向驱动力接收件4输出制动力,还可在处理盒取出过程中,减小制动部203a与驱动力接收件4之间的摩擦力;进一步的,在驱动力接收件4与力输出件203的结合过程中,活动结合部被制动部203a(第二制动结合构件204)压迫而向着靠近旋转轴线L21的方向变形,直至向内突出部208e越过凸缘部47进入限位空间482,驱动部的定位柱180i进入中心柱45的定位孔452中,随后,活动结合部复位,向内突出部208e与凸缘部47结合(卡接),同时,定位柱180i还将中心柱45/基板450向着远离旋转轴线L21的方向迫推/挤压,沿轴线M1,第一制动结合构件208在驱动力接收件4中被稳定的定位,第一制动结合构件208与凸缘部47实现紧密的结合,力输出件203可能的轴向移动被制止,力输出件203不会向着远离驱动力接收件4的方向缩回而与驱动力接收件4脱离结合,可见,本实施例中的活动结合部可相对于固定结合部在靠近旋转轴线L21和远离旋转轴线L21之间摆动,同时,向内突出部208e还与抵接面466保持抵接,力输出件203与驱动力接收件4的稳定结合可被保持。
[实施例十一]
图21A是本发明实施例十一涉及的驱动力接收件的立体图;图21B是本发明实施例十一涉及的驱动力接收件的分解示意图。
本实施例中的驱动力接收件4仍然包括所述固定结合部和活动结合部,与实施例五的不同之处在于,本实施例中的活动结合部的运动方式设置为滑动,具体为,活动结合部可相对于固定结合部在与旋转轴线L21相交的方向滑动,优选的,活动结合部的滑动方向与旋转轴线L21相互垂直。
如图所示,本实施例中的基座43也被切割,也就是说,本实施例中的固定结合部和活动结合部还包括基座43的一部分,为便于描述,将位于固定结合部中的基座称为第一基座43a,位于活动结合部中的基座称为第二基座43b,基部461和凸块462均位于第一基座43a的上方(远离连接部41的方向),中心柱45的一部分从第二基座43b向上延伸,凸缘部47位于中心柱45的自由末端,第二基座43b还设置有被导引部431,底盘42设置有导引部421,通过导引部421与被导引部431的配合,活动结合部可实现在与旋转轴线L21相交的方向滑动;优选的,被导引部431设置为被导引凹部,导引部421设置为导引突起,在所述被导引凹部431和导引突起至少之一还设置有限制活动结合部向着靠近旋转轴轴线L21运动的限制突起422。
在一些实施例中,被导引凹部和导引突起的位置还可以互换。
在一些实施例中,防脱部被设置为用于限制活动结合部向着远离旋转轴线L21的方向运动,所述防脱部和限制突起422共同在驱动力接收件4的径向方向对活动结合部的运动范围进行限制,一方面使得驱动力接收件4与力输出件203的结合更为稳定,另一方面,使得驱动力接收件4与力输出件203能够更容易脱离结合;如图21B所示,基座43设置有用于与防脱部4f结合的安装部483,优选的,防脱部为套接在 基座43外表面的弹性件4f,安装部483为设置在基座43的安装槽,防脱部4f被安装在安装槽483中,当活动结合部被作用力(如下述迫推件施加的迫推力)迫使向着远离旋转轴线L21的方向运动时,活动结合部迫使弹性件发生弹性变形,当作用力撤销时,弹性件迫推活动结合部向着靠近旋转轴线L21的方向运动。
在一些实施例中,驱动力接收件4还设置有用于将活动结合部向着远离旋转轴线L21迫推的迫推件,优选的,迫推件设置为具有弹性的弹性件,当驱动力接收件4与力输出件203完成结合时,驱动部的定位柱180i进入中心柱45的定位孔452中,迫推件发生弹性变形而产生向着远离旋转轴线L21的迫推力,在迫推件的迫推力作用下,凸缘部47与第二制动结合构件的向内突出部208e可结合的更紧密,力输出件203可能的轴向移动被制止,力输出件203不会向着远离驱动力接收件4的方向缩回而与驱动力接收件4脱离结合;当处理盒需要被取出时,随着驱动力接收件4向着远离力输出件203的方向被拉动,向内突出部208e挤压凸缘部47以克服迫推件的迫推力,活动结合部向着靠近旋转轴线L21的方向运动,直至向内突出部208e与凸缘部47脱离结合,随后,迫推件再次迫使活动结合部向着远离旋转轴线L21的方向运动。
与实施例十类似的,进入定位孔452中的定位柱180i也可以起着将活动结合部向着远离旋转轴线L21的方向挤压/迫推的作用,因而,即使在不设置所述弹性件的情况下,凸缘部47与向内突出部208e也能够实现紧密的结合,可见,定位柱180i也可以被视为迫推件的一种。
[实施例十二]
图22是本发明实施例十二涉及的驱动力接收件的立体图;图23A是本发明实施例十二涉及的驱动力接收件开始与力输出件结合的立体图;图23B是本发明实施例十二涉及的驱动力接收件与力输出件结合后的立体图;图23C是本发明实施例十二涉及的驱动力接收件与力输出件结合后,沿与驱动力接收件的旋转轴线垂直的方向观察的侧视图。
如图22所示,结合部44包括中心柱45、基部461和凸块462,沿与驱动力接收件的旋转轴线L21垂直的径向方向,中心柱45、基部461和凸块462依次远离旋转轴线L21,本实施例中,基部461绕中心柱45的外圆周表面延伸一周,即中心柱45被基部461包围,因而,所述基部461还可被视为压迫部48,基部461的末端面即为压迫面481/抵接面466;沿旋转轴线L21,凸块462比基部461延伸的更加远离连接部41,即凸块462超出压迫面481,同时,凸块462上还形成有接收驱动力的驱动面464。
进一步的,结合部44还包括设置在中心柱45的防脱部,优选的,防脱部为设置在或靠近中心柱45自由末端的凸缘部47,沿旋转轴线L21,凸缘部47与压迫面481之间形成限位空间482。
如图23A所示,在驱动力接收件4与力输出件203结合前,沿旋转方向r,驱动部180h与制动部203a相互分离,结合部44不必设置用于将制动部203a与驱动部180h分离的导引面,结合部44的结构可被简化。
在驱动力接收件4与力输出件203结合的过程中,制动部203a(第二制动结合构件的向内突出部208e)先是被凸缘部47压迫而缩回,随着处理盒C的安装,第二制动结合构件的向内突出部208e与凸缘部47相互挤压并最终越过凸缘部47进入限位空间482,同样的,驱动部的定位柱180i进入中心柱45的定位孔452中,制动部203a(第二制动结合构件的向内突出部208e)被所述压迫面481压迫而不能伸出,向内突出部208e与凸缘部47结合,力输出件203可能的轴向移动被制止,力输出件203不会向着远离驱动力接收件4的方向缩回而与驱动力接收件4脱离结合,凸块462进入驱动部180h与制动部203a之间,沿旋转方向,驱动力输出面180d与驱动面464相对,驱动力接收件4与力输出件203完成结合,随着驱动部180h开始沿r所示方向旋转,驱动力输出面180d向驱动面464输出驱动力,驱动力接收件4也沿r所示方向旋转,制动部203a将不再向驱动力接收件4输出制动力。
[实施例十三]
图24是本发明实施例十三涉及的驱动力接收件的分解示意图;图25A是本发明实施例十三涉及的驱动力接收件开始与力输出件结合的立体图;图25B是本发明实施例十三涉及的驱动力接收件与力输出件结合后的立体图;图25C是本发明实施例十三涉及的驱动力接收件与力输出件结合后,沿与驱动力接收件的旋转轴线垂直的方向观察的侧视图。
本实施例中,结合部44被设置成可沿旋转轴线L21相对于第二旋转件/感光鼓21或连接部41运动,即,结合部44可在靠近连接部41的位置(结合部缩回状态)和远离连接部41的位置(结合部伸出状态)之间运动。
如图所示,结合部44与基座43分体形成,驱动力接收件4还包括形成在基座43内部的活动腔432以及用于将结合部44保持在远离第二旋转件/感光鼓21或连接部41的位置的保持件49,保持件49优选设置为压缩弹簧;此时,驱动力接收件4可被分解为包括连接部41、底盘42和基座43的被结合部4z、与被结合部4z分体形成的结合部44以及位于被结合部和结合部之间的保持件49,被结合部4z用于将结合部44接收到的驱动力传递出去,所述保持件49用于沿旋转轴线L21将结合部44向着远离被结合部4z的方向迫推。结合部44包括底板441、从底板441一侧延伸的中心柱45和驱动力接收部46、从底板441另一侧延伸的驱动力传递部442,沿旋转轴线L21,中心柱45和驱动力接收部46向着远离连接部41的方向延伸,驱动力传递部442向着靠近连接部41的方向延伸。
驱动力接收部46仍然设置有导引面463和驱动面464,其中,在驱动力接收件4和力输出件203的结合过程中,导引面463用于迫使制动部203a相对于驱动部180h转动而使得制动部203a和驱动部180h相互分离,驱动面464用于接收驱动力。本实施例中的驱动力接收部46不设置用于接收制动力的制动面。
驱动力传递部442用于与基座43结合,以将驱动力接收部46接收到的驱动力传递至基座43,进而驱动与连接部41连接的旋转件21旋转。在一些实施例中,驱动力传递部442设置为沿旋转轴线L21从底板 441向着靠近连接部41的方向延伸的突起,相应的,活动腔432的侧壁设置有可与突起配合的凹槽433,或者,突起与凹槽的位置互换;底盘42形成为活动腔432的底壁,压缩弹簧49的一端与底盘42抵接,另一端与底板441面向连接部41的一侧表面抵接。
进一步的,结合部44还包括与驱动力传递部442同侧设置的导向结合柱443,相应的,底盘42上设置有与导向结合柱443配合的导向孔421,所述导向结合柱443被设置成可在与旋转轴线L21相交的方向弹性变形的悬臂,悬臂的末端设置有卡接突起444,在结合部44的安装过程中,导向结合柱443被挤压而发生弹性变形,卡接突起444与导向孔421卡接,结合部44与连接部41/基座43可实现稳定的结合;在结合部44沿旋转轴线L21运动的过程中,导向结合柱443与导向孔421的配合可确保结合部44的运动轨迹不发生偏移。
驱动力接收件4与力输出件203结合时,导引面463迫使制动部203a沿旋转方向r旋转而与驱动部180h相互分离,随后,沿旋转方向r,驱动面464与驱动力输出面180d相对,驱动力接收件4与力输出件203结合完成,驱动力接收件4即可接收驱动部180h输出的驱动力。
本实施例中,制动部203a在被导引面463迫推导引的同时还会逐渐向着缩回状态缩回,当驱动面464与驱动力输出面180d相对时,制动部203a既可以处于被导引面463压迫的状态,也可以不再被导引面463压迫而处于伸出的伸出状态,无论制动部203a处于何种状态均不会影响驱动力输出面180d向驱动面464输出驱动力,此时的制动部203a不会向驱动力接收件4施加制动力而可被视为被屏蔽。
与上述实施例不同的是,本实施例中的结合部44设置为可伸缩,在驱动力接收件4与力输出件203的结合过程中,制动部203a被导引面463压迫,反过来,导引面463也被制动部203a压迫,结合部44将向着靠近连接部41/感光鼓21的方向缩回,所述压缩弹簧49也会发生弹性变形,这样,驱动力接收部46将被压缩弹簧49向着力输出件203迫推,也就是说,驱动力接收部46可跟随驱动部180h/制动部203a运动,最后同样可使得驱动力接收件4与力输出件203保持稳定紧密的结合。
[实施例十四]
图26是本发明实施例十四涉及的驱动力接收件的分解示意图;图27A是本发明实施例十四涉及的驱动力接收件与力输出件结合前,驱动力接收件在处理盒中的状态图;图27B是本发明实施例十四涉及的驱动力接收件与力输出件结合前的立体图;图28是本发明实施例十四涉及的驱动力接收件与力输出件结合后,驱动力接收件在处理盒中的状态图。
实施例十三中的结合部44可在压缩弹簧49的迫推力作用下跟随驱动部180h/制动部203a运动而确保驱动力接收件4与力输出件203保持稳定紧密的结合,即结合部44可主动跟随驱动部180h/制动部203a运动,本实施例中的结合部44将被设置为被动跟随驱动部180h/制动部203a运动。
如图所示,保持件49优选设置为拉簧,所述拉簧49用于将结合部44保持在结合部缩回状态。驱动 力接收件4还包括结合部结合的作用件4e,所述作用件4e可活动地安装在驱动端盖300/非驱动端盖400/第一单元壳体1/第二单元壳体2,作用件4e用于在接收外部作用力时迫使结合部44从结合部缩回位置向着结合部伸出位置运动。
结合部44的结构以及结合部44与基座43结合的结构与实施例十三相同,在此将重点描述作用件4e及其运动过程。
作用件4e优选为可活动地设置在处理盒中的作用杆,作用杆4e包括中间杆4e1以及分别位于中间杆4e1两端的受力部4e2和迫推部4e3,迫推部4e3设置为叉状,包括与中间杆4e1连接的两个迫推杆4e31,至少一个迫推杆4e31设置有相对于旋转轴线L21倾斜的迫推面4e32,两个迫推杆4e31之间形成容纳空间4e30。
图27A示出了作用杆4e被安装在驱动端盖300的示例,在驱动力接收件4与力输出件203结合前,结合部44处于结合部缩回状态,迫推面4e32与底板441面向连接部41一侧的表面相对;随着受力部4e2接收到外部作用力F,迫推面4e32开始迫推底板441,进而使得结合部44逐渐向着结合部伸出状态运动,如图27B所示,设置在结合部44中的导引面463迫使制动部203a沿旋转方向r远离驱动部180h,随后,驱动面464与驱动力输出面180d相对;如上所述,力输出件203可沿轴线M1向着凸缘部分180a的方向(远离驱动力接收件4的方向)运动,在驱动力接收件4与力输出件203结合的过程中,如果力输出件203被压迫而向着凸缘部分180a的方向运动,那么在迫推杆4e31的迫推作用下,结合部44也将被动的跟随力输出件203运动,直至力输出件203不再沿轴线M1向着凸缘部分180a的方向运动,最后,结合部44与力输出件203可保持稳定紧密的结合。
优选的,驱动力接收件4还包括用于迫使作用杆4e复位的复位件(未示出),例如,该复位件为安装在作用杆4e与处理盒壳体/端盖之间的压缩弹簧或拉簧;如图28所示,结合部44处于结合部伸出状态,复位件发生弹性变形,当施加至受力部4e2的外部作用力F撤销时,复位件释放复位力,作用杆4e复位,同时,拉簧49将结合部44从伸出状态拉回至缩回状态。
在一些实施例中,所述外部作用力F可以来自于成像设备的门盖,在门盖关闭的过程中,门盖向受力部4e2施加作用力。
在一些实施例中,所述外部作用力F还可以来自于成像设备的内壁,现有一种设置有抽屉式容纳部的成像设备,处理盒被安装在所述抽屉式容纳部中,在需要安装或取出处理盒时,门盖打开,抽屉式容纳部先随着门盖的打开而上升一段距离,然后被拉出,当安装或取出处理盒后,抽屉式容纳部被向着成像设备内部推动至预定位置,最后在关闭门盖的过程中,抽屉式容纳部再下降一端距离而与成像设备中设置的转印装置相互靠近。对于此种成像设备,所述外部作用力可以是抽屉式容纳部被向着成像设备内部推动的过程中,成像设备内壁与受力部4e2相互干涉所产生,也可以是在关闭门盖的过程中,抽屉式容纳部下降 时,转印装置与受力部4e2相互干涉所产生;在一些实施例中,关闭门盖的过程中,抽屉式容纳部不下降,而是与抽屉式容纳部相对的转印装置上升实现与抽屉式容纳部相互靠近,所述外部作用力则是转印装置上升时,转印装置与受力部4e2相互干涉所产生。
[实施例十五]
图29是本发明实施例十五涉及的驱动力接收件的立体图;图30A是本发明实施例十五涉及的驱动力接收件与处于第一种状态下的力输出件结合前,沿与驱动力接收件的旋转轴线相交的方向观察时的立体图;图30B是本发明实施例十五涉及的驱动力接收件与处于第一种状态下的力输出件结合后,沿与驱动力接收件的旋转轴线相交的另一方向观察时的立体图;图31A是本发明实施例十五涉及的驱动力接收件与处于第一种状态下的力输出件结合后的立体图;图31B是本发明实施例十五涉及的驱动力接收件与处于第一种状态下的力输出件结合后,沿与驱动力接收件的旋转轴线垂直的方向观察时的立体图;图32是本发明实施例十五涉及的驱动力接收件开始与处于第二种状态下的力输出件结合时,沿与驱动力接收件的旋转轴线垂直的方向观察时的立体图。
以上描述了利用驱动部180h中设置的驱动力输出面180d向驱动力接收件4施加驱动力的实施例,然而,在力输出件203的工作过程中,制动部203a也将跟随驱动部180h转动,因而,制动部203a也可以作为向驱动力接收件4施加驱动力的部件,下面将描述制动部203a与驱动力接收件4结合传递驱动力的实施例。
如图29所示,驱动力接收部46仍然包括位于中心柱45径向外侧的基部461和凸块462,其中,凸块462比基部461更远离旋转轴线L21,凸块462设置有用于接收驱动力的驱动面464,该驱动面464既可以与第一制动结合构件204结合,也可以与第二制动结合构件208结合,本实施例将对驱动面464与第二制动结合构件208结合进行描述。
如上所述,沿力输出件203的径向方向,第二制动结合构件208位于第一制动结合构件204的内侧,优选的,沿旋转方向r,驱动面464将与第二制动结合构件208相对。
如图所示,沿旋转方向r,第二制动结合构件208具有位于下游的内输出面208f,相对于旋转轴线L21,内输出面208f向着与旋转方向r相反的方向呈螺旋上升设置,优选的,驱动面464被设置为与内输出面208f配合的螺旋面。
如图30A、图30B、图31A和图31B所示,其中,为更清楚的展示第二制动结合构件208与驱动力接收件2的结合状态,图31B中隐藏了驱动部180h和第一制动结合构件204。
在驱动力接收件4与力输出件203结合前,沿旋转方向r,驱动部180h和制动部203a相互远离,在驱动力接收件4与力输出件203结合的过程中,如果制动部203a与凸块462抵接,那么制动部203a将被压迫而缩回,随着力输出件203旋转,当驱动部180h与制动部203a抵接时,驱动部180h和制动部203a 一起沿r所示方向旋转,直至凸块462不再与制动部203a和驱动部180h抵接,制动部203a和驱动部180h将伸出,如图31B所示,内输出面208f与驱动面464抵接,第二制动结合构件208开始向驱动力接收件4输出驱动力,且制动部203a将不再向驱动力接收件4施加制动力。
如图32所示,在驱动力接收件4与力输出件203结合前,沿旋转方向r,驱动部180h和制动部203a相互靠近,随着处理盒C的安装,凸块462挤压驱动部180h和/或制动部203a,驱动部180h和/或制动部203a缩回;随着驱动部180h旋转,驱动部180h将推动制动部203a一起旋转,当驱动部180h和/或制动部203a不再被凸块462挤压时,力输出件203内设置的第一弹簧/鼓驱动联轴器弹簧210和/或第二弹簧/制动结合弹簧211释放弹力而使得驱动部180h和/或制动部203a伸出,随后,内输出面208f与驱动面464抵接,第二制动结合构件208开始向驱动力接收件4输出驱动力,且制动部203a将不再向驱动力接收件4施加制动力。
进一步的,基部461还设置有保持面4611,沿旋转轴线L21,保持面4611面向连接部41,沿与旋转轴线L21垂直的径向方向,保持面4611比驱动面464更靠近旋转轴线L21,内输出面208f与驱动面464抵接时,第二制动结合构件的内突起部208e与保持面4611抵接,制动部203a可被保持在与驱动力接收件4稳定紧密结合的状态,因而,保持面4611可被视为防脱部47的一个实施例。
更进一步的,基部461还包括与保持面4611相邻设置的导引面463,如图30A和图30B所示,在驱动力接收件4与力输出件203的结合过程中,导引面463与制动部203a抵接而将内突起部208e导引至与保持面4611结合的位置以及将外输出面204g/内输出面208f导致至与驱动面464相对的位置。
[实施例十六]
图33是本发明实施例十六涉及的驱动力接收件的立体图;图34A是本发明实施例十六涉及的驱动力接收件与驱动部结合后的立体图;图34B是本发明实施例十六涉及的驱动力接收件与驱动部结合后,沿与驱动力接收件的旋转轴线垂直的方向观察时的侧视图。
与实施例十五不同的是,本实施例中的驱动力接收件4被第一制动结合构件204驱动,沿旋转方向r,第一制动结合构件204具有位于下游的外输出面204g,所述外输出面204g也被设置为沿与旋转方向r相反的方向向上螺旋延伸。
如图33所示,本实施例中的驱动力接收部46包括位于中心柱45径向外侧的基部461和凸块462,所述凸块462比基部461更远离旋转轴线L21,可与外输出面204g配合的驱动面464设置在凸块462上,沿与旋转轴线L21垂直的径向方向,驱动面464与中心柱45之间还形成有避让部468,具体的,避让部468形成在凸块462上。
如图34A所示,为更清楚展示避让部468的功能,图中隐藏了第一制动结合构件204,本实施例中的结合部44/驱动力接收件4与力输出件203的结合过程与实施例十五相同,在此不再赘述,但当驱动力接 收件4与力输出件203完成结合时,第二制动结合构件208的至少一部分进入避让部468,如图34B所示,外输出面204g与驱动面464抵接,第一制动结合构件204开始向驱动力接收件4输出驱动力,且制动部203a将不再向驱动力接收件4施加制动力。
优选的,本实施例中的基部461也可以设置上述保持面4611或设置粗糙面或设置附加有弹性橡胶的表面,在外输出面204g与驱动面464抵接的同时,进入避让部468的第二制动结合构件208的内突起部208e还与保持面4611/粗糙面/附加有弹性橡胶的表面结合,因而,制动部203a可被保持在与驱动力接收件4稳定紧密结合的状态。
可选的,当结合部44中不设置保持面4611时,所述形成保持面4611的基部461也可以被省却,但沿驱动力接收件4的径向方向,位于中心柱45与凸块462之间的底板441可以被视为基部461,结合部44的结构可被简化。
如上所述,保持面4611可用于防止驱动力接收件4与力输出件203脱离结合,因而,保持面4611或设置为粗糙面或设置附加有弹性橡胶的表面也可被视为防脱部47的一个实施例;在防脱部47的各个实施例中,本领域技术人员可根据设计需求进行选择,以确保驱动力接收件4和力输出件203稳定紧密的结合。

类似实施例十三和实施例十四的,本实施例中,结合部44与被结合部4z也分体形成,这样,结合部44与被结合部4z可采用不同的材质制造,例如,结合部44由金属制成,被结合部4z由树脂材料制成,用于与力输出件203结合和脱离结合的结合部44将变得更耐磨,硬度更高;在一些实施例中,结合部44和被结合部4z还可以由同一种材质制成。
如图36所示,结合部44具有底板441以及从底板441的一侧延伸形成的驱动力传递部442,相应的,被结合部4z设置有可与驱动力传递部442结合的活动腔432,中心柱45和驱动力接收部46均从底板441的另一侧延伸形成,也就是说,驱动力接收部46通过底板441与中心柱45连接,因而,底板441的至少一部分还可以被视为基部461。
驱动力接收部46包括位于中心柱45径向外侧的基部461和凸块462,所述凸块462比基部461更远离旋转轴线L21,所述驱动力接收部46被设置为与制动部203a结合,当力输出件203沿旋转方向r旋转时,制动部203a中的外输出面204g和内输出面208f至少之一向驱动力接收部46输出驱动力。
与实施例十六类似的,沿与旋转轴线L21垂直的径向方向,驱动面464与中心柱45之间还形成有避让部468,具体的,避让部468设置在凸块462上,当驱动力接收件4与力输出件203结合时,第二制动结合构件208进入避让部468,第一制动结合构件204与驱动面464相对,因而,力输出件203向驱动力接收件4输出驱动力的方式有下面三种:
第一种,第一制动结合构件204的外输出面204g与驱动面464结合,第二制动结合构件208不与避让部468中的表面接触,力输出件203的驱动力由第一制动结合构件204传递至驱动力接收件4;
第二种,第一制动结合构件204的外输出面204g不与驱动面464结合,第二制动结合构件208与避让部468中的表面接触,力输出件203的驱动力由第二制动结合构件208传递至驱动力接收件4,此时,驱动力接收部46中用于接收驱动力的面将是避让部468中的所述表面;
第三种,第一制动结合构件204的外输出面204g与驱动面464结合,第二制动结合构件208也与避让部468中的表面接触,力输出件203的驱动力由第一制动结合构件204和第二制动结合构件208同时传递至驱动力接收件4,此时,驱动面464和避让部468中的所述表面均为用于接收驱动力的面。
进一步的,驱动力接收部46还包括设置在用于接收驱动力的面上的突起469,当驱动力接收件4与力输出件203结合时,突起469与制动部203a结合,在制动部203a向驱动力接收件4输出驱动力的过程中,制动部203a将受到来自驱动力接收件4的反作用力而具有与驱动力接收件4脱离结合的趋势,上述突起469的设置,可增大制动部203a与驱动力接收件4之间的摩擦力,进而防止驱动力接收件4与制动部203a脱离结合,因而,突起469也可被视为上述防脱部47的一种实施例。
用于接收驱动力的面(以驱动面464为例)具有与外输出面204g和/或内输出面208f匹配的形状,且多个突起469设置在用于接收驱动力的面上,如图37和图38所示,用于接收驱动力的面设置为绕旋转轴线L21延伸的螺旋面。当沿着与旋转轴线L21垂直的方向观察时,突起469整体向着感光鼓21/连接部41的一侧倾斜,并具有面向感光鼓21/连接部41的表面4691,从而增大力输出件203与驱动力接收件4之间的摩擦力;可替换的,所述多个突起469还可以由粗糙面、弹性橡胶等替换。
当结合部44和被结合部4z不需要由不同材质制成时,所述结合部44和被结合部4z还可以一体形成,因而,驱动力接收件4的制造将变得更容易。
[实施例十八]
图39是本发明实施例十八涉及的驱动力接收件的立体图。
本实施例在实施例十七的基础上将凸块462的结构进一步简化,如图所示,沿与旋转轴线L21垂直的径向方向,驱动面464与中心柱45之间也形成有避让部468,但该避让部468不再形成在凸块462上,而是位于凸块462与中心柱45之间,也就是说,沿与旋转轴线L21垂直的径向方向,凸块462与中心柱45之间的空间即为避让部468。
当驱动力接收件4与力输出件203结合时,第二制动结合构件208进入避让部468,设置在凸块462上的驱动面464与外输出面204g相对,力输出件203输出的驱动力由外输出面204g传递至驱动面464。
可变换的是,驱动力接收件4还可以设置成,当驱动力接收件4与力输出件203结合时,驱动面464与内输出面208f相对,力输出件203输出的驱动力由内输出面208f传递至驱动面464。
[实施例十九]
图40是本发明实施例十九涉及的驱动力接收件的立体图;图41是本发明实施例十九涉及的驱动力接收件与力输出件结合后的立体图。
根据力输出件203的结构,本实施例中的驱动力接收件4被设置成,当驱动力接收件4与力输出件203结合时,驱动力接收件4与所述第二制动结合构件208的平面208g结合。
驱动力接收部46包括设置在凸块462的导引面463以及与导引面463相邻设置的驱动面464,其中,驱动面464为与平面208g匹配的表面,如图40所示,驱动面464与旋转轴线L21平行。
优选的,导引面463设置为绕旋转轴线L21延伸的螺旋面,如图41所示,在驱动力接收件4与力输出件203结合的过程中,导引面463被外输出面204g或内输出面208f导引,因而,驱动力接收部46可顺利的到达平面208g与驱动面464相对的位置,随着力输出件203的旋转,驱动力从平面208g被传递至驱动464。
[实施例二十]
图42A是本发明实施例二十涉及的驱动力接收件的立体图;图42B是沿本发明实施例二十涉及的驱动力接收件的旋转轴线观察时的侧视图;图43是本发明实施例二十涉及的驱动力接收件与力输出件结合后的立体图;图44是本发明实施例二十涉及的驱动力接收件与力输出件结合后,沿图43中的AA方向剖切的剖视图。
根据力输出件203的结构,本实施例中的驱动力接收件4被设置成,当驱动力接收件4与力输出件203结合时,驱动力接收件4与所述驱动部180h的前表面180g1结合。
如图42A和图42B所示,驱动力接收部46包括位于中心柱45径向外侧的基部461和凸块462,所述凸块462比基部461更远离旋转轴线L21,凸块462形成沿旋转轴线L21延伸的条状体,并仍然设置有导引面463和驱动面464,其中,导引面463设置为相对于旋转轴线L21倾斜的斜面或螺旋面,驱动面464与导引面463相邻设置,且驱动面464能够与前表面180g1匹配。
如图43所示,当驱动力接收件4与力输出件203结合时,导引面463在倾斜面180j的导引作用下进入到驱动部180h/驱动力输出面180d与制动部203a之间,且驱动面464与前表面180g1相对,随着力输出件203的旋转,驱动力通过前表面180g1被传递至驱动面464,优选的,前表面180g1和驱动面464 均被设置为相对于旋转轴线L21/M1平行。
进一步的,驱动力接收部46还包括加强部46e,沿旋转方向r,凸块462与加强部46e间隔设置,其中,凸块462用于接收驱动力而可被称为被驱动部46d,加强部46e用于增强驱动力接收件4的强度,防止驱动力接收件4在接收驱动力的过程中被折断,还可以防止驱动力接收件4在与力输出件203结合前被以外碰撞而翻滚折断。
如图44所示,当驱动力接收件4与力输出件203结合时,设置在第一连接件181的前表面180g1与被驱动部46d抵接,加强部46e与第二连接件182抵接,不仅可确保被驱动部46d与前表面180g1稳定的结合,还能起到为被驱动部46d定位的作用。
在本实施例的变形方式中,继续如图44所示,驱动面464还可以被设置成通过与子前表面180g2抵接而接收驱动力,沿旋转方向r,子前表面180g2与第一制动接合构件208相对并相互分离,当驱动面464与子前表面180g2抵接时,凸块462不会与第一制动结合构件208接触,可见,在该变形方式中,不需要将驱动部180h与制动部203a相互分离也能由驱动部180h向凸块462输出驱动力。
[实施例二十一]
图45是本发明实施例二十一涉及的驱动力接收件的立体图;图46A是本发明实施例二十一涉及的驱动力接收件与力输出件结合前,沿与驱动力接收件的旋转轴线垂直的方向观察时的侧视图;图46B是本发明实施例二十一涉及的驱动力接收件与力输出件的结合过程中,沿与驱动力接收件的旋转轴线垂直的方向观察时的侧视图;图46C是本发明实施例二十一涉及的驱动力接收件与力输出件结合后,沿与驱动力接收件的旋转轴线垂直的方向观察时的侧视图。
本实施例中的驱动力接收件4仍然被设置为与力输出件203中的驱动部180h结合,同时,制动部203a被压迫而向着设备内缩回,驱动力接收件4不再接收制动部203a输出的制动力;本实施例中的结合部44的结构被进一步完善,驱动力接收件4的其他结构可参照上述实施例。
结合部44包括中心柱45位于中心柱45径向外侧的驱动力接收部46,旋转轴线L21穿过中心柱45,两个驱动力接收部46径向相对设置,每个驱动力接收部46的结构相同,下面描述其中一个。
驱动力接收部46包括与中心柱45连接的基部461以及位于基部461径向外侧的凸块462,导引面463从基部461向着凸块462延伸,沿旋转方向r,导引面463具有位于上游末端的末端部(末端分隔线)463f,其中,位于凸块462上的导引面被称为第一接触面463a,位于基部461上的导引面被称为第二接触面463b,沿驱动力接收件4的径向方向,所述第一接触面463a位于第二接触面463b的径向外侧,所述第一接触面463a和第二接触面463b可以是一整个连续的面,也可以是两个间断的面,所述第一接触面463a和第二接触面463b可以形成为平面、曲面、螺旋面至少之一,只要能够起到下述的导引作用即可。
进一步的,驱动力接收部46还设置有抵接面466,沿旋转方向r,抵接面466与接触面463相邻设 置,在驱动力接收件4和力输出件203的结合过程中以及完成结合后,抵接面466用于与制动部203a抵接,使得制动部203a向着成像设备内缩回,可理解的,抵接面466与导引面463可以形成为一个连续的表面,也可以在二者之间形成间隙,使得二者不连续,但只要导引面463能够将制动部203a导引至抵接面466即可。
可见,沿旋转方向r,抵接面466与第一接触面463a和第二接触面463b至少之一位于同一个圆周上即可,换句话说,当将驱动部44投影在与旋转轴线L21垂直的平面上时,以旋转轴线L21的投影点为圆心,经过抵接面466的一个圆周经过第一接触面463a,经过抵接面466的另一个圆周经过第二接触面463b,还可以是,经过抵接面466的任意圆周仅经过第一接触面463a或第二接触面463b。
如上所述,抵接面466与制动部203a抵接,使得制动部203a向着成像设备内部缩回而被屏蔽,在一些实施方式中,结合部44还包括位于抵接面466径向外侧的非抵接部,在驱动力接收件4与力输出件203/驱动部180h结合的过程中,抵接面466与第二制动结合构件208抵接,第一制动结合构件204与非抵接部相对,制动部203a被屏蔽而不再输出制动力;在另一些实施方式中,结合部44还包括位于抵接面466径向内侧的非抵接部,在驱动力接收件4与输出件203/驱动部180h结合的过程中,抵接面466与第一制动结合构件204抵接,第二制动结合构件208与非抵接部相对,制动部203a被屏蔽而不再输出制动力,可见,非抵接部和抵接面466在驱动力接收件4的径向方向相邻设置即可,具体的,非抵接部可以被设置为凹槽、缺口等形状,还可以被设置为能够与制动部203a接触的弹性件,但该弹性件的弹力不足以迫使制动部203a向着成像设备内部缩回;在另一些实施例中,抵接面466同时抵接第一制动结合构件204和第二制动结合构件208,制动部203a被屏蔽而不再输出制动力。
沿旋转方向r,抵接面466包括与第一接触面463a相对的第一抵接面466a以及与第二接触面463b相对的第二抵接面466b,其中,第一抵接面466a位于第二抵接面466b的径向外侧,同样的,沿驱动力接收件4的径向方向,第一抵接面466a和第二抵接面466b可以是一整个连续的面,也可以是两个间断的面,所述第一抵接面466a和第二抵接面466b可以形成为平面、曲面、螺旋面至少之一,只要能够起到压迫制动部203a,使得制动部203a不再向驱动力接收件4输出制动力的作用即可。
当第一抵接面466a和第二抵接面466b为两个间断的面时,根据力输出件203的结构,沿旋转轴线L21测量,驱动力接收件4还具有不同于抵接面466,且与旋转轴线L21垂直的第二特定面,第一抵接面466a到第二特定面的距离和第二抵接面466b到第二特定面的距离不同,可见,第一特定面和第二特定面可以是同一个面,也可以是不同的面,优选的,第二抵接面466b到所述第二特定面的距离大于第一抵接面466a到第二特定面的距离,即沿旋转轴线L21,第一抵接面466a比第二抵接面466b更靠近连接部41。
在一些实施方式中,所述离连接部41更远的抵接面466a/466b还可以是驱动力接收件的末端面。
进一步的,凸块462设置有用于与驱动部180h抵接的驱动面464,所述驱动面464可被设置成与驱 动部180h中的驱动力输出面180d和前表面180g1至少之一配合,从而,驱动部180h能够驱动所述驱动力接收件4绕旋转轴线L21沿旋转方向r旋转。
沿驱动力接收件4的径向方向,驱动面464位于基部461的径向外侧,如图45所示,凸块462设置有驱动空间46c,沿驱动力接收件4的径向方向,基部461面向驱动空间46c,驱动面464形成为驱动空间46c的一个表面,沿旋转方向r,驱动面464位于驱动空间46c的下游末端。所述驱动空间46c用于容纳驱动部180h,优选的,沿旋转方向r,驱动空间46c与驱动部180h为松配合,这样,驱动部180h能够顺利的出入驱动空间46c。
当驱动力接收件4沿旋转轴线L21向着力输出件203运动时,沿旋转轴线L21,将制动部203a向着驱动力接收件4投影,优选的,如图46A所示,沿旋转方向r,制动部203a位于末端部463f的下游,具体的,第二制动结合构件的内突起部208e位于末端部463f的下游,另外,当沿着旋转轴线L21观察时,末端部463f与第三空间K3相对。
当驱动力接收件4继续沿旋转轴线L21运动时,如图46B所示,定位凸台180i进入定位孔452中,第二制动接合构件的内突起部208e与第二接触面463b抵接而被导引,制动部203a沿旋转方向r转动,或者驱动力接收件4反转(沿与旋转方向r相反的方向转动),第一制动结合构件204逐渐与第一接触面463a抵接而被导引,同时,驱动面464逐渐进入第三空间K3,如图46C所示,制动部203a被导引至与抵接面466抵接,随着驱动力接收件4的继续运动,制动部203a被抵接面466向着成像设备内部(图中M1A所示方向)压迫而缩回,沿旋转方向r,驱动力输出面180d和前表面180g1至少之一与驱动面464相对。当驱动部180h随着力输出件203沿旋转方向r转动时,驱动力接收件4通过驱动面464从驱动部180h接收到驱动力而旋转,制动部203a处于被抵接面466压迫的状态而不会向驱动力接收件4输出作用力/制动力。
在一些实施方式中,导引面463还包括设置在基部461上的第三接触面463e,沿旋转方向r,第三接触面463e的延伸方向与第一接触面463a/第二接触面463b的延伸方向相反,在驱动力接收件4与力输出件203开始结合时,如果末端部463f不与第三空间K3相对,此时,在第三接触面463e的导引下,力输出件203与驱动力接收件4相互干涉的风险可被降低。
[实施例二十二]
图47是本发明实施例二十二涉及的驱动力接收件的立体图;图48A是本发明实施例二十二涉及的驱动力接收件与力输出件结合前,沿与驱动力接收件的旋转轴线垂直的方向观察时的侧视图;图48B是本发明实施例二十二涉及的驱动力接收件与力输出件的结合过程中,沿与驱动力接收件的旋转轴线垂直的方向观察时的侧视图;图48C是本发明实施例二十二涉及的驱动力接收件与力输出件结合后,沿与驱动力接收件的旋转轴线垂直的方向观察时的侧视图。
在实施例二十一的基础上,本实施例中的驱动部44还设置有凸缘部47以及由两个相邻的凸缘部47形成的具有定位导向面471的导向槽472,优选的,所述凸缘部47设置在中心柱45的径向外侧。
为更清楚的观察到制动部203a在导向槽472中运动,图48A、图48B和图48C分别在各自状态下,经过与旋转轴线L21垂直且经过中心柱的自由末端451的平面对力输出件203进行了剖切。
如图48A所示,定位柱180i进入到定位孔452中,制动部203a进入到导向槽472中,并被导向面471导向,随着驱动力接收件4与力输出件203的继续结合,力输出件203沿旋转方向r转动,或者驱动力接收件4沿与旋转方向r相反的方向转动;如图48B所示,制动部203被导引至与导引面463抵接,具体的,第二制动结合构件208或所述内突起部208e与第二接触面463b抵接,第一制动结合构件204与第一接触面463a抵接,驱动部180h开始进入驱动空间46c;随后,制动部203a逐渐与被抵接面466抵接,驱动部180h进入驱动空间46c,沿旋转方向r,驱动力输出面180d和前表面180g1至少之一与驱动面464相对,驱动力接收件4与力输出件203完成结合,且制动部203保持在被所述抵接部466抵接而向着成像设备内部缩回的状态,驱动部180h通过驱动力输出面180d和前表面180g1至少之一向驱动面464输出驱动力,进而使得驱动力接收件4绕旋转轴线L21沿旋转方向r旋转。
本实施例中的导向槽472的设置,一方面,可使得驱动力接收件4与力输出件203更顺利的结合,在驱动力接收件4与力输出件203的结合过程中,如果制动部203不能直接与导引面463相对/抵接,随着力输出件203的旋转,制动部203进入到导向槽472并被导引,最后,制动部203顺利的到达与导引面463相对/抵接的位置;另一方面,通过导向槽472,驱动部180h相对于驱动力接收件4的位置可被定向,优选的,沿旋转轴线L21观察或者沿与旋转轴线L21垂直的方向观察,驱动空间46c的至少一部分与导向槽427相对,或者说,沿旋转方向r,驱动面464位于导向槽472的至少一部分的下游,这样,当制动部203a进入到导向槽472后,与制动部203a相邻的驱动部180h也能够与驱动空间46c在旋转轴线L21的方向上相对。
如上所述,凸缘部47被设置为在驱动力接收件4的径向方向突出,因而,凸缘部47的设置还可以起到防止制动部203a/力输出件203与驱动力接收件4相互脱开的作用,即,凸缘部47相当于上述防脱部,如图48C所示,当驱动力接收件4与力输出件203完成结合后,第二制动接合机构的内突起部208e到达凸缘部47与抵接面466之间,制动部203a/力输出件203沿图62C中M1A所示方向向着成像设备内部运动的趋势可被凸缘部47制止。
[实施例二十三]
图49是本发明实施例二十三涉及的驱动力接收件的立体图。
在实施例二十二的基础上,本实施例对结合部44做进一步改善,以提升驱动部180h与驱动力接收件4的结合稳定性,如图49所示,结合部44还包括从导引面463向着自由末端451(远离连接部41的方向) 延伸的延伸部463g,沿旋转方向r,所述延伸部463g与驱动空间46c相邻,延伸部463g面向驱动空间46c的表面463g1比驱动面464更靠近自由末端451,从而,驱动力接收件4与驱动部180h接触位置的强度得到加强。
基于本实施例的发明构思,沿旋转方向r,所述表面463g1可以位于驱动面464的上游或下游,优选的,沿旋转方向r,所述表面463g1与驱动面464重合,沿驱动力接收件4的旋转轴线L21,所述表面463g1与驱动面464形成为一整个连续的面,此时,驱动力接收件4与驱动部180h的接触面积得到增大,驱动力接收件4和驱动部180h的磨损可被减小,且驱动部180h与驱动面464之间的驱动力传递更平稳。
如上所述,本发明中的驱动力接收件被设置为,当驱动力接收件4与力输出件203结合后,制动部203a被驱动力接收件4屏蔽而不向驱动力接收件4施加制动力,沿驱动力接收件4的旋转方向r,结合部44中用于接收驱动力的表面与驱动部180h相对,所述制动部203a被屏蔽,即制动部203a不再向驱动力接收件4输出制动力,有利于减小驱动力接收件4受到的磨损;另一方面,由于制动部203a被驱动部180h驱动而旋转,当制动部203a被屏蔽后,驱动部180h将不再需要驱动制动部203a,此时,成像设备的输出功率可减小,或者在成像设备的输出功率不变的情况下,驱动部180h将能够向驱动力接收件输出更大的驱动力,有利于处理盒C中另外设置更多被驱动的部件,例如,在处理盒C中增加在驱动端C1和非驱动端C2之间传递驱动力的部件,以丰富非驱动端C2的功能等。可理解的,本领域的技术人员可以根据设计需求将上述各个实施例相互交叉结合以实现本发明的目的。
