本申请提供的电子设备1000包括第一壳体组件200、第二壳体组件300和平衡驱动机构100,第二壳体组件300与第一壳体组件200滑动连接,平衡驱动机构100的驱动组件101驱动平衡组件102运动,以带动第二壳体组件300相对于第一壳体组件200滑动,可实现第二壳体组件300相对于第一壳体组件200的展开、闭合,而驱动组件101固定连接第一壳体组件200,平衡组件102的第一运动臂120的第一连接端120a活动连接驱动组件101,第一运动臂120的第二连接端120b活动连接第二壳体组件300,第二运动臂121的第三连接端121a活动连接第一壳体组件200,第二运动臂121的第四连接端121b活动连接第二壳体组件300,使得平衡组件102在带动第二壳体组件300相对于第一壳体组件200滑动的过程中可以提高电子设备1000的运动平衡、稳定性,从而能够提升电子设备1000的闭合效果,减少电子设备1000的外观缝隙。
其中,第一连接端120a与第三连接端121a间隔设置,第二连接端120b与第四连接端121b间隔设置,第一连接端120a与第三连接端121a之间的连线平行于第二连接端120b与第四连接端121b之间的连线。
在一种应用场景中,第一运动臂120在驱动组件101的作用下运动,并带动第二壳体组件300相对于第一壳体组件200滑动;第二壳体组件300在相对于第一壳体组件200滑动的过程中,受到第一运动臂120的第一连接端120a与第二运动臂121的第三连接端121a间隔设置,第一运动臂120的第二连接端120b与第二运动臂121的第四连接端121b间隔设置以及第一运动臂120的第一连接端120a与第二运动臂121的第三连接端121a之间的连线平行于第一运动臂120的第二连接端120b与第二运动臂121的第四连接端121b之间的连线的限制,使得第二壳体组件300在第一运动臂120与第二运动臂121的共同作用下相对于第一壳体组件200平行地滑动。在另一种应用场景中,第一运动臂120在驱动组件101的作用下运动,并带动第二运动臂121运动;第一运动臂120与第二运动臂121共同带动第二壳体组件300相对于第一壳体组件200滑动,第二壳体组件300在相对于第一壳体组件200滑动的过程中,受到第一运动臂120的第一连接端120a与第二运动臂121的第三连接端121a间隔设置,第一运动臂120的第二连接端120b与第二运动臂121的第四连接端121b间隔设置以及第一运动臂120的第一连接端120a与第二运动臂121的第三连接端121a之间的连线平行于第一运动臂120的第二连接端120b与第二运动臂121的第四连接端121b之间的连线的限制,从而相对于第一壳体组件200平行地滑动。其中,第一运动臂120可以理解为主动臂,第二运动臂121可以理解为从动臂。当然,在其他实施例中,还可以通过驱动组件101连接第二运动臂121,并驱动第二运动臂121运动,此时,第一运动臂120、第二运动臂121皆可以理解为主动臂。
由于驱动组件101固定连接第一壳体组件200,因此,第一连接端120a可以理解为平衡组件102连接 第一壳体组件200的连接端。平衡组件102连接第一壳体组件200的第一连接端120a与第三连接端121a之间的连线平行于平衡组件102连接第二壳体组件300的第二连接端120b与第四连接端121b之间的连线,即第二连接端120b与第四连接端121b之间的第二壳体组件300平行于第一连接端120a与第三连接端121a之间第一壳体组件200,从而可以通过设计第一连接端120a与第三连接端121a之间的间距、第二连接端120b与第四连接端121b之间的间距,平衡驱动机构100的数量,使第二壳体组件300在滑动过程中相对于第一壳体组件200平行。换言之,本申请提供的电子设备1000中,平衡驱动机构100的驱动组件101用于驱动平衡组件102运动,平衡组件102在运动的过程中用于带动第二壳体组件300平行地靠近或远离第一壳体组件200。

其中,第二连接端120b转动连接第二壳体组件300的方式与上述实施例中第二连接端120b转动连接第二壳体组件300的方式可以相同,第三连接端121a滑动连接第一壳体组件200的方式与上述实施例中第三连接端121a滑动连接第一壳体组件200的方式可以相同,此处不再赘述。与上述实施例不同的是:第四连接端121b与第二壳体组件300之间的连接方式。本实施例中,第四连接端121b与第二壳体组件300之间为转动连接。可选的,第四连接端121b与第二壳体组件300之间可以通过转轴与轴孔的配合、转轴与轴套的配合转动连接。在一种可能的实施方式中,平衡组件102还包括第六轴承和第六销轴。第四连接端121b与第二壳体组件300之间通过第六轴承和第六销轴转动连接。具体的,第二运动臂121的第四连接端121b设有第十一轴孔。第二壳体组件300设有第十二轴孔,第二销轴125穿设于第十一轴孔和第十二轴孔内。第二轴承124位于第十一轴孔内,并固定于第二销轴125与第三轴孔1215的内壁之间。第二 运动臂121通过第六轴承相对于第二壳体组件300转动。
第一运动臂120与第二运动臂121可以交叉设置,也可以平行设置。当第一运动臂120与第二运动臂121可以交叉设置时,第一运动臂120与第二运动臂121可以在交叉位置处转动连接。
可选的,如图22所示,第一连接端120a滑动连接驱动组件101,第二连接端120b转动连接第二壳体组件300,第三连接端121a转动连接第一壳体组件200,第四连接端121b滑动连接第二壳体组件300。可以理解的,驱动组件101可以驱动第一连接端120a滑动;第二连接端120b可以相对于第二壳体组件300转动;第三连接端121a可以相对于第一壳体组件200转动;第四连接端121b可以相对于第二壳体组件300滑动。第一连接端120a在驱动组件101的驱动下的滑动方向,第四连接端121b相对于第二壳体组件300的滑动方向相互平行。本申请中,第一连接端120a在驱动组件101的驱动下的滑动方向、第四连接端121b相对于第二壳体组件300的滑动方向皆垂直于第二壳体组件300相对于第一壳体组件200的滑动方向。换言之,第一连接端120a在驱动组件101的驱动下沿Y轴方向滑动。第四连接端121b相对于第二壳体组件300的滑动方向沿Y轴方向。通过使第一连接端120a在驱动组件101的驱动下沿垂直于第二壳体组件300相对于第一壳体组件200的滑动方向滑动,第四连接端121b相对于第二壳体组件300的滑动方向垂直于第二壳体组件300相对于第一壳体组件200的滑动方向,可以使平衡组件102在运动过程中第一连接端120a与第三连接端121a之间的连线始终平行于第二连接端120b与第四连接端121b之间的连线,从而使第二壳体组件300始终与第一壳体组件200保持平行,实现第二壳体组件300在任意位置时的平衡。
其中,第二连接端120b转动连接第二壳体组件300的方式与上述实施例中第二连接端120b转动连接第二壳体组件300的方式可以相同,第四连接端121b滑动连接第二壳体组件300的方式与上述实施例中第四连接端121b滑动连接第二壳体组件300的方式可以相同,此处不再赘述。与上述实施例不同的是:第三连接端121a与第一壳体组件200之间的连接方式。本实施例中,第三连接端121a与第一壳体组件200之间为转动连接。可选的,第三连接端121a与第一壳体组件200之间可以通过转轴与轴孔的配合、转轴与轴套的配合转动连接。在一种可能的实施方式中,平衡组件102还包括第七轴承和第七销轴。第三连接端121a与第一壳体组件200之间通过第七轴承和第七销轴转动连接。具体的,第二运动臂121的第三连接端121a设有第十三轴孔。第一壳体组件200设有第十四轴孔,第三销轴穿设于第十三轴孔和第十四轴孔内,并与第十四轴孔的内壁固定连接。第二轴承124位于第十三轴孔内,并固定于第二销轴125与第五轴孔的内壁之间。第二运动臂121通过第三轴承相对于第一壳体组件200转动。
第一运动臂120与第二运动臂121可以交叉设置,也可以平行设置。当第一运动臂120与第二运动臂121可以交叉设置时,第一运动臂120与第二运动臂121可以在交叉位置处转动连接。
以下实施例以第一连接端120a转动连接驱动组件101,第二连接端120b滑动连接第二壳体组件300,第三连接端121a滑动连接第一壳体组件200,第四连接端121b滑动连接第二壳体组件300,第二连接端120b相对于第二壳体组件300的滑动方向、第三连接端121a相对于第一壳体组件200的滑动方向、以及第四连接端121b相对于第二壳体组件300的滑动方向相互平行,且皆垂直于第二壳体组件300相对于第一壳体组件200的滑动方向为例,对本申请的驱动组件101以及第一连接端120a与驱动组件101的转动连接方式进行详细的描述。
请参照图23和图24,平衡驱动机构100还包括传动组件103。传动组件103用于将驱动组件101输出的运动和动力传递至第一运动臂120,以驱动第一运动臂120运动。传动组件103包括第一齿轮130和第二齿轮131。第一齿轮130可以为圆柱形齿轮、锥形齿轮、蜗轮等。第二齿轮131可以为圆柱形齿轮、锥形齿轮、蜗轮等。第一齿轮130固定连接驱动组件101。第一齿轮130可以通过粘接、卡扣连接、螺纹连接等固定连接方式与驱动组件101连接。第二齿轮131固定连接第一连接端120a。第二齿轮131可以通过粘接、卡扣连接、螺纹连接等固定连接方式与第一运动臂120连接。本实施例中,第二齿轮131转动中心处形成第一运动臂120的第一连接端120a;当然,在其他实施例中,当第一运动臂120与驱动组件101通过转轴与轴孔的配合,转轴与轴套的配合转动连接时,可近似将第一运动臂120与驱动组件101的连接处,或者两者的转动中心理解为第一连接端120a。第二齿轮131的齿数大于第一齿轮130的齿数。通过使第二齿轮131的齿数大于第一齿轮130的齿数可以减小第一运动臂120运动时的速度,增大第一运动臂120的扭矩,从而实现省力的效果。第二齿轮131与第一齿轮130啮合以使第一连接端120a转动连接驱动组件101。
通过传动组件103实现第一运动臂120的第一连接端120a与驱动组件101的转动连接,可提高平衡驱动机构100的运动可靠性,降低平衡驱动机构100的尺寸,且适用于第一运动臂120、驱动组件101在空间的多种摆放场景。
在一种可能的实施例中,第一齿轮130为柱形齿轮。第二齿轮131为扇形齿轮。第二齿轮131与第一齿轮130外啮合。第二齿轮131与第一齿轮130外啮合是指第二齿轮131的外部与第一齿轮130的外部啮合,即第二齿轮131的外表面具有用于啮合的凸齿和齿槽,第一齿轮130的外表面具有用于啮合的凸齿和齿槽,第二齿轮131与第一齿轮130啮合时,第二齿轮131的凸齿与第一齿轮130的齿槽配合,第二齿轮131的齿槽与第一齿轮130的凸齿配合。本实施例通过使第一齿轮130为柱形齿轮,第二齿轮131为扇形齿轮,第二齿轮131与第一齿轮130外啮合可以缩减第二齿轮131的尺寸,从而有利于降低平衡驱动机构100占用的空间,便于电子设备1000内部器件的排布。
进一步地,如图25所示,第二齿轮131的内侧设有至少一个棘齿1310。电子设备1000还包括棘爪1311。在第二壳体组件300相对于第一壳体组件200静止时,棘爪1311与一个棘齿1310相配合以使第二壳体组件300与第一壳体组件200之间形成自锁。本申请对于棘齿1310的数量不做具体的限定。当棘齿1310的数量为一个时,可以实现平衡驱动机构100在一个位置的自锁。当棘齿1310的数量为多个时,可以实现平衡驱动机构100在多个位置的自锁,即实现平衡驱动机构100的无极自锁。
在一种应用场景中,当第二壳体组件300相对于第一壳体组件200从闭合状态切换为展开状态的过程中,第二齿轮131正向转动,棘齿与棘爪之间接触但未配合,此时第二壳体组件300与第一壳体组件200未形成自锁,可实现第二壳体组件300相对于第一壳体组件200的滑动。当第二壳体组件300相对于第一壳体组件200运动至展开状态时,第二壳体组件300相对于第一壳体组件200静止,第二齿轮131停止转动,棘齿与棘爪配合,实现自锁,可避免电子设备1000在展开状态时发生碰撞、跌落或者受到用户握力时自动闭合。当第二壳体组件300相对于第一壳体组件200从展开状态切换为闭合状态的过程中,第二齿轮131反向转动,此时可通过驱动结构(例如:电机)驱动棘爪,使棘爪与棘齿分离,从而避免棘爪对棘齿的运动阻碍,此时第二壳体组件300与第一壳体组件200之间也未形成自锁,可实现第二壳体组件300相对于第一壳体组件200的滑动。当第二壳体组件300相对于第一壳体组件200运动至闭合状态时,第二壳体组件300相对于第一壳体组件200静止,第二齿轮131停止转动,此时可通过驱动件再次驱动棘爪,使棘爪与棘齿配合,实现自锁,可避免电子设备1000在闭合状态时发生碰撞、跌落时自动展开。其中,当棘齿的数量为多个时,在第二壳体组件300相对于第一壳体组件200从闭合状态切换为展开状态的过程中,若第二壳体组件300停止滑动,此时,棘爪与棘齿也可以配合,实现第二壳体组件300与第一壳体组件200在中间状态(闭合状态与展开状态之间的一种状态)的自锁。
如图26所示,驱动组件101包括底座110、设于底座110上的驱动电机112和设于底座110上的减速器113。底座110固定连接第一壳体组件200。减速器113的输入轴连接驱动电机112的输出轴,减速器113的输出轴与第一齿轮130同轴设置且固定连接。减速器113可以是齿轮减速器113、蜗杆减速器113和行星齿轮减速器113等。通过底座110固定连接第一壳体组件200,使电机、减速器113设于底座110上,可增加驱动组件101与第一壳体组件200之间的连接面积,提高驱动组件101与第一壳体组件200之间的连接可靠性。驱动电机112作为驱动平衡组件102运动的动力源,可以降低平衡驱动组件101的重量,提高平衡驱动组件101的响应速度。减速器113可以降低平衡组件102转速,增大驱动电机112的输出扭矩,降低负载的惯量。
在一种可能的实施例中,减速器113为蜗杆-涡轮式减速器。减速器113包括相啮合的蜗杆和涡轮,蜗杆连接减速器113的输入轴,涡轮连接减速器113的输出端,蜗杆的导程角小于涡轮和蜗杆之间的当量摩擦角,在第二壳体组件300相对于第一壳体组件200静止时,蜗杆和涡轮相配合以使第二壳体组件300与第一壳体组件200之间形成自锁。本实施例中,蜗杆停止转动时,蜗轮给蜗杆的反向作用力,不能使蜗杆反向转动,从而可以实现电子设备1000在展开状态时的自锁功能,避免电子设备1000在展开状态时发生碰撞、跌落或者受到用户握力时自动闭合。
进一步地,如图27所示,驱动组件101还包括弹性件114。弹性件114可以是弹簧、弹片、波纹管等。弹性件114的一端连接底座110,弹性件114的另一端连接第一运动臂120。弹性件114与底座110之间可以直接连接,也可以通过其他结构件连接;弹性件114与第一运动臂120之间可以直接连接,也可以通过其他结构件连接。在第二壳体组件300远离第一壳体组件200的过程中,弹性件114逐渐伸展以带动第一运动臂120运动,在第二壳体组件300靠近第一壳体组件200的过程中,弹性件114逐渐压缩以缓冲第一运动臂120的运动。在第二壳体组件300与第一壳体组件200处于闭合状态时,弹性件114压缩于底座110与第一运动臂120之间。在第二壳体组件300与第一壳体组件200处于展平状态时,弹性件114可恢复至平衡状态。
在一种可能的实施例中,底座110的一端与第一运动臂120通过插销转动连接,第一运动臂120与插销固定连接,底座110还包括限位壁,弹性件114为扭矩弹簧,弹性件114的一端连接限位壁,另一端连接插销。在第二壳体组件300与第一壳体组件200处于闭合状态时,弹性件114压缩于限位壁与插销之间。当第二壳体组件300远离第一壳体组件200时,弹性件114在限位壁与插销之间逐渐伸展,恢复弹力以带动第一运动臂120运动,从而与驱动电机112共同驱动平衡组件102运动。当第二壳体组件300靠近第一壳体组件200时,弹性件114在限位壁与插销之间逐渐缩紧,以阻碍第一运动臂120的运动,从而起到缓冲的作用,使得平衡组件102、第二壳体组件300在运动过程中更平稳。
请参照图28至图31,电子设备1000还包括柔性显示屏400,其中,图30为柔性显示屏400处于展开状态时的结构示意图,图31为柔性显示屏400处于闭合状态时的结构示意图。柔性显示屏400处于展开状态时对应电子设备1000处于展开状态,柔性显示屏400处于闭合状态对应电子设备1000处于闭合状态。在一种实施例中,柔性显示屏400包括彼此相连的第一显示部401和第二显示部402。其中,第一显示部401为正常显示部,第二显示部402为扩展显示部。可以理解的,第一显示部401在柔性显示屏400处于展开状态以及闭合状态时皆可以进行显示,第二显示部402仅在柔性显示屏400处于展开状态时进行显示。第一显示部401固定连接第一壳体组件200,第二显示部402随第二壳体组件300相对于第一壳体组件200的滑动而展开或收卷。
其中,第一显示部401可以固定连接于第一壳体201、第一支撑件202上。第二显示部402与第二壳体301、第二支撑件302之间未连接。第一支撑件202可以在展开状态和闭合状态时支撑第一显示部401,以提高第一显示部401承受按压的能力,提高柔性显示屏400的使用寿命。第二支撑件302可以在展开状态支撑第二显示部402,以提高第二显示部402承受按压的能力,提高柔性显示屏400的使用寿命。此外,由于本申请实施例中,第二支撑件302与第一支撑件202之间通过滑槽220与支撑杆320的配合滑动连接。
在一种实施例中,请参照图32和图33,电子设备1000还包括回收组件500。回收组件500包括滚轮501和绕设于滚轮501上的连接带502。滚轮501设于第二壳体组件300上。可选的,滚轮501固定于第二壳体301上。连接带502的一端连接第一壳体组件200,连接带502的另一端连接第二显示部402。在第二壳体组件300相对于第一壳体组件200的滑动时,第二壳体组件300带动滚轮501滚动,以通过连接带502辅助第二显示部402展开或收卷。
在一种应用场景中,当电子设备1000从闭合状态切换为展开状态的过程中,第二壳体组件300逐渐远离第一壳体组件200,并带动滚轮501逐渐远离第一壳体组件200,滚轮501与连接带502之间产生摩擦力,使得连接带502的另一端逐渐远离第一壳体组件200,从而辅助第二显示部402展开。当电子设备1000从展开状态切换为闭合状态的过程中,第二壳体组件300逐渐靠近第一壳体组件200,并带动滚轮501逐渐靠近第一壳体组件200,滚轮501与连接带502之间产生摩擦力,使得连接带502的另一端逐渐靠近第一壳体组件200,从而辅助第二显示部402收卷。
进一步地,电子设备1000还可以包括电连接组件。电连接组件可以包括柔性电路板、电连接线等。至少部分电连接组件固定于平衡机构上,电连接组件用于第一壳体组件200与第二壳体组件300之间的多个电子元器件的电连接。第一壳体组件200与第二壳体组件300之间的多个电子元器件可以包括主板、其他电路板、听筒、扬声器、摄像头模组、各种传感器、天线、震动器等。通过将电连接组件固定于平衡驱动机构100上,可以提高多个电子元器件的电连接可靠性。
本申请提供的电子设备1000由于第一壳体组件200与第二壳体组件300之间设有平衡驱动机构100,平衡驱动机构100可驱动第二壳体组件300相对于第一壳体组件200滑动,且在第二壳体组件300相对于第一壳体组件200滑动过程中使第二壳体组件300与第一壳体组件200保持平行,避免第二壳体组件300发生倾斜,从而可提高电子设备1000的运动平稳性、外观合拢效果。平衡驱动机构100包括驱动组件101和平衡组件102,平衡组件102的结构简单,有利于电子设备1000的安装和拆卸,且平衡组件102的重量小,有利于电子设备1000的轻量化。平衡驱动机构100还包括传动组件103,驱动组件101包括驱动电机112和减速器113,传动组件103与减速器113可以降低平衡组件102的转动速度,提高扭矩,有利于省力。此外,平衡驱动机构100与第一壳体组件200、第二壳体组件300之间的转动连接通过轴承实现,可以降低电子设备1000的摩擦,从而减少负载,节省电量。第二壳体组件300的第二支撑件302、第二壳体组件300的第一支撑件202可分别支撑柔性显示屏400的第二显示部402、第一显示部401,提高柔性显示屏400的受力性能,减小柔性显示屏400的变形。
上述在说明书、权利要求书以及附图中提及的特征,只要在本申请的范围内是有意义的,均可以任意相互组合。尽管上面已经示出和描述了本申请的实施例,可以理解的是,上述实施例是示例性的,不能理解为对本申请的限制,本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型,这些改进和润饰也视为本申请的保护范围。
