请结合图1、图2和图3,本实施方式的电子设备100包括壳组件10、柔性显示屏20和引导件30。壳组件10为中空结构,柔性显示屏20、引导件30等均可设置在壳组件10。电子设备100还可以包括电路板(未图示)、电池(未图示),电路板、电池均可以设置于壳组件10。电路板可以集成电子设备100的处理器、电源管理模块、存储单元和基带芯片等。柔性显示屏20与电路板通信连接,电池能够为柔性显示屏20及电路板上的电子元件供电。当然,电子设备100还可以包括摄像头模组(未图示),摄像头模组与电路板通信连接,电池能够为摄像头模组供电。可以理解的是,本申请实施方式的电子设备100包括但不限于手机、平板电脑等终端设备或者其它便携式电子设备100。在本申请实施方式中,以手机为例进行说明。
壳组件10包括第一壳体12和第二壳体14,第二壳体14和第一壳体12能够相对运动。具体地,在本实施方式中,第二壳体14和第一壳体12滑动连接。换言之,第二壳体14能够相对第一壳体12滑动,以使第二壳体14的远离第一壳体12的一端与第一壳体12的远离第二壳体14的一端产生相互靠近或者相背远离的运动。
进一步,第二壳体14能够相对第一壳体12滑动至第一位置和第二位置。结合图1,第二壳体14在第一位置时,电子设备100可以获得相对较大的显示面积,以提升电子设备100的使用体验;结合图2,第二壳体14在第二位置时,电子设备100具有相对较小的外形尺寸,便于携带。可以理解的是,在本申请后文的实施方式中,第一位置、第二位置及类似的表述均是指第二壳体14与第一壳体12的相对位置。为简化表述,“第二壳体14位于第一位置”或者“在第一位置时”这种类似的表述是指第二壳体14相对第一壳体 12处于第一位置,“第二壳体14位于第二位置”或者“在第二位置时”这种类似的表述是指第二壳体14相对第一壳体12处于第二位置。
在本实施方式中,以第一位置作为参考,可以更清楚地确定第二壳体14的远离第一壳体12的一端、以及第一壳体12的远离第二壳体14的一端的位置。以图3为例,当第二壳体14处于第一位置时,电子设备100的宽度方向的最左侧即是第二壳体14的远离第一壳体12的一端,电子设备100的宽度方向的最右侧即是第一壳体12的远离第二壳体14的一端。
在本实施方式中,第二壳体14在第一位置时,电子设备100的整机宽度大于在第二位置的宽度,以使暴露的柔性显示屏20的宽度尺寸可变。换言之,电子设备100在宽度方向的尺寸可变。在这种实施方式中,电子设备100的接口例如数据线插孔或者充电线插孔或者耳机插孔可以设置于宽度方向的端部。在其他实施方式中,第二壳体14在第一位置时,电子设备100的整机长度大于在第二位置的长度,以使暴露的柔性显示屏20的长度尺寸可变。换言之,电子设备100在长度方向的尺寸可变。在这种实施方式中,电子设备100的接口例如数据线插孔或者充电线插孔或者耳机插孔可以设置于长度方向的端部。
再参阅图1和图2,柔性显示屏20可以包括相对设置的固定部20a和自由部20b,固定部20a设置于第一壳体12并与第一壳体12的位置相对固定。在第二位置时柔性显示屏20绕过引导件30,且柔性显示屏20的自由部20b容纳于壳组件10内,以使部分柔性显示屏20隐藏于壳组件10,隐藏于壳组件10内的部分柔性显示屏20可不用于显示。换言之,第一壳体12相对第二壳体14的移动可以使得至少部分自由部20b展开于第二壳体14,或使展开于第二壳体14的自由部20b收回壳组件10内。
可以理解的是,在本申请实施方式中,两物的位置相对固定意即两物在正常情况下不能产生相对运动,位置相对固定的两物可以存在物理上的直接连接,也可以通过中间结构实现间接连接。以固定部20a与第一壳体12为例,固定部20a与第一壳体12的位置相对固定,可以是固定部20a与第一壳体12直接接触,例如采用螺纹紧固件或者卡持等方式实现固定部20a与第一壳体12的直接固定,也可以是固定部20a通过粘胶层、中间连接板等结构实现固定部20a与第一壳体12的间接固定。
可以理解的是,固定部20a和自由部20b可以按照以下方式进行区分,参考图2,在第二壳体14相对第一壳体12处于第二位置时,外露于壳组件10外的那部分柔性显示屏20即为柔性显示屏20的固定部20a,收容于壳组件10内的那部分柔性显示屏20即可视为自由部20b。在一些实施方式中,第二壳体14位于第二位置时,暴露于壳组件10外的固定部20a大致呈矩形状,其尺寸可以为5~6英寸,即与一般的智能手机的显示屏的尺寸相当,以使电子设备100便于携带且使用较为方便。
第二壳体14还可以包括后盖(未图示),在第二位置时后盖覆盖柔性显示屏20的自由部20b。后盖可以设置透光区域,在第二位置时收容于壳组件10的那部分柔性显示屏20也可以用于显示,以使用户能够从透光区域查看柔性显示屏20显示的信息,进而拓展电子设备100的使用场景。例如,在这种实施方式中,电子设备100无需设置前置摄像头,采用后置式的摄像头模组40即可实现自拍、视频通话等功能。透光区域可以由透明玻璃构成,亦可以是后盖的开孔形成。第二壳体14相对第一壳体12滑动至第一位置后,收容于壳组件10的至少部分柔性显示屏20暴露。暴露的柔性显示屏20可用于显示,以使得电子设备100具有相对较大的显示面积,以提升用户的使用体验。
继续参阅图3,在本实施方式中,引导件30设置于第二壳体14的远离第一壳体12的一端,在第二壳体14相对第一壳体12从第二位置切换至第一位置的过程中,引导件30可以引导柔性显示屏20变形并展开于第二壳体14。引导件30可以将柔性显示屏20的弯曲半径限制在适宜的范围内,以避免弯曲半径过小造成柔性显示屏20的损伤。当然,引导件30也可以避免柔性显示屏20弯曲半径过大造成电子设备100厚度过大。
在一些实施方式中,引导件30可为带有凸齿的转轴结构,柔性显示屏20通过啮合等方式与引导件30相联动。第二壳体14相对第一壳体12滑动时,通过引导件30带动啮合于引导件30上的部分柔性显示屏20移动并展开或收回壳组件10内。
如图3所示,在另一些实施方式中,引导件30为不附带齿的圆轴。在第二壳体14由第二位置切换至第一位置的过程中,通过引导件30将贴合于引导件30上的部分柔性显示屏20撑开,以使更多的柔性显示屏20暴露于壳组件10外侧,并处于平展状态。在这种实施方式中,引导件30可以转动地设置于第二壳体14,在逐步展开柔性显示屏20的过程中,引导件30可随柔性显示屏20的移动而转动,以减小柔性显示屏20在展开过程中所受到的阻力,并减小引导件30与柔性显示屏20的接触部位的磨损。
在其他实施方式中,引导件30也可固定在第二壳体14上,引导件30具有光滑的表面。在将柔性显示屏20展开至第二壳体14的过程中,引导件30通过其光滑的表面与柔性显示屏20可滑动接触。换言之,在这种实施方式中,引导件30可以和第二壳体14一体成型或者焊接成型,引导件30可以视为第二壳体14的一部分,柔性显示屏20的自由部20b绕过第二壳体14的远离第一壳体12的一端并伸入壳组件10内。
在第二壳体14由第一位置切换至第二位置的过程中,柔性显示屏20可通过引导件30带动收回,即使得展开于第二壳体14的那部分柔性显示屏20收回壳组件10内。参考图3,电子设备100可以包括驱动机构40,驱动机构40可设置在壳组件10内,驱动机构40可与第一壳体12或者第二壳体14相联动,以驱动第二壳体14相对第一壳体12移动,进而带动柔性显示屏20展开或收回。在一些实施方式中,驱动机构40采用了螺纹传动机构,即驱动机构40可以包括与电路板通信连接的电机41、与电机41的输出端联动的螺杆43,以及与螺杆43螺纹传动的螺母45。电机41可以连接于第一壳体12,螺母45可以连接于第二壳体14,以通过驱动机构40驱使第二壳体14相对第一壳体12移动。在另一些实施方式中,驱动机构40也可以采用齿轮传动机构,例如通过齿轮驱动齿条移动,即可实现第二壳体14相对第一壳体12的移动。可以理解的是,驱动机构40可以省略,用户可以直接通过手动等方式来使得第二壳体14和第一壳体12相对移动。
可以理解的是,在本实施方式中,第一位置、第二位置可以视为第二壳体14相对第一壳体12运动的两个极限位置。在第一位置时,柔性显示屏20的显示面积达到最大状态,在正常情况下,第二壳体14不能再相对第一壳体12做相对远离运动。在第二位置时,柔性显示屏20的显示面积达到最小状态,在正常情况下,第二壳体14不能再相对第一壳体12做相向靠近运动。第一位置和第二位置可以通过在设置限位结构来实现。例如,第一壳体12和第二壳体14中的一者可以设置弹片,另一者设有卡槽,在第一位置和第二位置时,弹片卡合于卡槽,以使第一壳体12和第二壳体14的位置相对固定。
可以理解的是,在第一位置和第二位置之间还可以设置多个中间位置,以实现第二壳体14相对第一壳体12在多个中间位置的定位,并使得柔性显示屏20在不同的中间位置具有不同的显示面积,从而拓展电子设备100的使用场景。多个中间位置同样可以采用限位结构来实现。
参考图4和图5,联动机构50包括第一支架51a、第二支架51b、第一轮52a、第二轮52b、驱动件53和两个第一支臂54a。第一支架51a、第二支架51b、第一支臂54a大致呈杆状,且两个第一支臂54a的长度可以相等,第一支架51a与第二支架51b的长度可以相等。第一支架51a的长度方向、第二支架51b的长度方向可以与第二壳体14相对第一壳体12的滑动方向垂直。第一支架51a连接于第一壳体12,第二支架51b连接于第二壳体14,驱动件53连接于第二支架51b且驱动件53连接于驱动机构40的输出端。例如,参考图3,在驱动机构40采用螺纹传动机构的实施方式中,驱动件53连接于螺母45。驱动机构40可以通过螺母45带动第二支架51b沿螺杆43的长度方向移动,即使得第二支架51b相对第一支架51a移动,并带动第二壳体14相对第一壳体12移动。
其中一个第一支臂54a与第一壳体12相联动且设有第一轮52a,第一轮52a可与第一支臂54a转动连接。另一个第一支臂54a与第二壳体14相联动且设有第二轮52b,第二轮52b可与另一第一支臂54a转动连接,第二轮52b与第一轮52a相联动。在第二壳体14相对第一壳体12滑动以带动至少部分柔性显示屏20进出壳组件10的过程中,第二支架51b带动两个第一支臂54a同步摆动。在本实施方式中,第一支架51a固定连接于第一壳体12,第二支架51b固定连接于第二壳体14。与第一支架51a联动的第一支臂54a转动连接于第一支架51a,与第二支架51b联动的第一支臂54a转动连接于第二支架51b。
在第二壳体14相对第一壳体12滑动以带动柔性显示屏20进出壳组件10的过程中,在第二壳体14相对远离第一壳体12时,第二壳体14可通过第二支架51b拉动与第二支架51b连接的第一支臂54a,并通过第一轮52a与第二轮52b的联动带动另一第一支臂54a同步摆动;在第二壳体14相对靠近第一壳体12时,第二壳体14可通过第二支架51b推动与第二支架51b连接的第一支臂54a,并通过第一轮52a与第二轮52b的联动带动另一第一支臂54a同步摆动。在本实施方式中,第一轮52a和第二轮52b均为齿轮,且两者啮合传动。在另一些实施方式中,第一轮52a和第二轮52b可以为摩擦轮以实现摩擦传动。在其他实施方式中,第一轮52a和第二轮52b之间还可设置两个以上的中间轮,这种设置同样能够实现第一轮52a与第二轮52b的同步转动,此处不再赘述。
由于第一轮52a与第二轮52b相联动,在第二壳体14相对第一壳体12滑动的过程中,在考虑工程误差的情况下,可以认为在任意时间段内,与第二支架51b连接的第一支臂54a相对第二支架51b的转动角度、与第一支架51a连接的第一支臂54a相对第一支架51a的转动角度相等,因此只需保证初始位置例如第一位置或者第二位置时,与第二支架51b连接的第一支臂54a与第二支架51b的夹度、与第一支架51a连接的第一支臂54a与第一支架51a的夹角相等,也即保证初始位置时第二壳体14相对第一壳体12的滑动方向与两个第一支臂54a的夹角相等,即可在进出壳组件10的过程中,保证第二壳体14相对第一壳体12的滑动方向与两个第一支臂54a的夹角保持相等。
参考图6,在一些实施方式中,第一支架51a可以设有滑槽51a1,驱动件53穿设于滑槽51a1并与滑槽51a1滑动配合。滑槽51a1至少可以在电子设备100的厚度方向对驱动件53的移动进行导向和限位,以防止驱动件53在移动过程中发生偏斜。当然,滑槽51a1也可以用于在垂直于第二壳体14相对第一壳体12的移动方向上对驱动件53进行导向和限位,以进一步提升驱动件53的运动平稳性。
在一些实施方式中,第一支架51a可以包括本体511和挡板(未图示),挡板可拆卸地连接于本体511并覆盖滑槽51a1。例如,挡板可以采用螺纹紧固件实现与本体511的可拆卸连接,亦可采用卡接等方式实现与本体511的可拆卸连接。这种结构设置有利于联动机构50的组装、拆卸和维修。本体511可连接于第一壳体12,两个第一支臂54a可以分别转动连接于本体511。
参考图7,在一些实施方式中,驱动件53还可以设有限位筋531,限位筋531可以视为驱动件53的一部分。在驱动件53设有限位筋531的一侧,驱动件53的除限位筋531以外的部分可以形成平整的表面,限位筋531凸出于该平整表面。限位筋531可用于抵持于滑槽51a1的槽壁,以限制驱动件53在第一支架51a的移动范围。例如,在图7所示实施方式中,限位筋531设置于驱动件53的远离第二支架51b的一端。在第二壳体14相对第一壳体12移动至第一位置时,限位筋531抵接于滑槽51a1处的第一支架51a,进而限定了驱动件53的移动范围,也限定了第二壳体14的移动范围。
可以理解的是,第一支架51a、第二支架51b的设置有利于整个联动机构50的组装及模块化设计,从而可以将联动机构50组装成为独立的部件再与第一壳体12、第二壳体14进行组装,以提升电子设备100的组装效率,并提升联动机构50的通用性。当然,第一支架51a、第二支架51b不是必须的,驱动件53可以直接连接在第二壳体14上,其中 一个第一支臂54a可连接在第一壳体12上,另一个第一支臂54a可连接在第二壳体14上。
参考图5,联动机构50还可以包括设于第一支架51a和第二支架51b之间的第一连接件55,第一轮52a和第二轮52b分别转动连接于第一连接件55,在第二壳体14相对第一壳体12滑动的过程中,两个第一支臂54a带动第一连接件55运动。第一连接件55可用于保证第一轮52a与第二轮52b的传动连接,防止第一轮52a与第二轮52b脱离。
继续参阅图4和图5,联动机构50还可包括第三轮56a、第四轮56b、第二连接件57和两个第二支臂58a,在垂直于第二壳体14相对第一壳体12的运动方向上,第一轮52a、第二轮52b位于驱动件53的一侧,第三轮56a、第四轮56b位于驱动件53的相对的另一侧。其中一个第二支臂58a转动连接于第一支架51a且设有第三轮56a,第三轮56a可与第二支臂58a转动连接,另一个第二支臂58a转动连接于第二支架51b且设有第四轮56b,第四轮56b可与另一第二支臂58a转动连接。第三轮56a、第四轮56b分别转动连接于第二连接件57且相联动。在第二壳体14相对第一壳体12滑动的过程中,第二支架51b带动第二连接件57及两个第二支臂58a同步摆动,且与第一壳体12联动的第一支臂54a、第二支臂58a的摆动方向相反,与第二壳体14联动的第一支臂54a、第二支臂58a的摆动方向相反。
第二连接件57和两个第二支臂58a可以分别呈杆状,且第二支臂58a的长度可以和第一支臂54a的长度相等。在本实施方式中,第三轮56a和第四轮56b均为齿轮且转动连接于第二连接件57,第三轮56a和第四轮56b的啮合传动即可实现两个第二支臂58a的同步摆动。在另一些实施方式中,第三轮56a和第四轮56b可以为摩擦轮以实现摩擦传动。在其他实施方式中,第三轮56a和第四轮56b之间还可设置两个以上的中间轮,这种设置同样能够实现第三轮56a与第四轮56b的同步转动,此处不再赘述。第二连接件57可用于保证第三轮56a和第四轮56b的传动连接,防止第三轮56a和第四轮56b脱离。
在第二壳体14相对第一壳体12滑动以带动柔性显示屏20进出壳组件10的过程中,在第二壳体14相对远离第一壳体12时,第二壳体14可通过第二支架51b拉动与第二支架51b连接的第二支臂58a,并通过第三轮56a与第四轮56b的联动带动另一第二支臂58a同步摆动;在第二壳体14相对靠近第一壳体12时,第二壳体14可通过第二支架51b推动与第二支架51b连接的第二支臂58a,并通过第三轮56a与第四轮56b的联动带动另一第二支臂58a同步摆动。
由于第三轮56a与第四轮56b相联动,在第二壳体14相对第一壳体12滑动的过程中,在考虑工程误差的情况下,可以认为在任意时间段内,与第二支架51b连接的第二支臂58a相对第二支架51b的转动角度、与第一支架51a连接的第二支臂58a相对第一支架51a的转动角度相等,因此只需保证初始位置例如第一位置或者第二位置时,与第二支架51b连接的第二支臂58a与第二支架51b的夹度、与第一支架51a连接的第二支臂58a与第一支架51a的夹角相等,也即保证初始位置时第二壳体14相对第一壳体12的滑动方向与两个第二支臂58a的夹角相等,即可在进出壳组件10的过程中,保证第二壳体14相对第一壳体12的滑动方向与两个第一支臂54a的夹角保持相等。
参阅图5,在第二壳体14相对第一壳体12滑动的过程中,连接于第一支架51a的第一支臂54a相对第一支架51a的转动方向、与连接于第一支架51a的第二支臂58a相对第一支架51a的转动方向相反,连接于第二支架51b的第一支臂54a相对第二支架51b的转动方向、与连接于第二支架51b的第二支臂58a相对第二支架51b的转动方向相反。
例如,在图4所示实施例中,在第二支架51b相对远离第一支架51a时,连接于第一支架51a的第一支臂54a相对第一支架51a的转动方向为逆时针,连接于第一支架51a的第二支臂58a相对第一支架51a的转动方向为顺时针;连接于第二支架51b的第一支臂54a相对第二支架51b的转动方向为顺时针,连接于第二支架51b的第二支臂58a相对第二支架51b的转动方向为逆时针。
又如,在图5所示实施例中,在第二支架51b相对靠近第一支架51a时,连接于第一支架51a的第一支臂54a相对第一支架51a的转动方向为顺时针,连接于第一支架51a的第二支臂58a相对第一支架51a的转动方向为逆时针;连接于第二支架51b的第一支臂54a相对第二支架51b的转动方向为逆时针,连接于第二支架51b的第二支臂58a相对第二支架51b的转动方向为顺时针。
这种设置可以实现较好的力平衡效果,使得连接于第一支架51a的第一支臂54a对第一支架51a的作用力,与连接于第一支架51a的第二支臂58a对第一支架51a的作用力,在垂直于第二壳体14相对第一壳体12的移动方向上的分力相抵消;且使得连接于第二支架51b的第一支臂54a对第二支架51b的作用力,与连接于第二支架51b的第二支臂58a对第二支架51b的作用力,在垂直于第二壳体14相对第一壳体12的移动方向上的分力相抵消,进而保证第二支架51b相对第一支架51a的运动平稳性,并保证第二壳体14相对第一壳体12的滑动平稳性。
结合两个第一支臂54a的摆动,只需使得与第二支架51b连接的第二支臂58a与第二支架51b的初始夹角、与第二支架51b连接的第一支臂54a与第二支架51b的初始夹角相等,即使得初始位置时第一支架51a与第二支架51b相互平行,即可在第二壳体14相对第一壳体12的滑动过程中,保证第一支架51a相对第二支架51b的平行移动,防止第一支架51a相对第二支架51b产生偏斜或偏斜趋势,进而防止第二壳体14在相对第一壳体12滑动过程中产生偏斜或偏斜趋势。这种结构设置既能保证相关运动机构(例如第一壳体12、第二壳体14、第一支架51a、第二支架51b、两个第一支臂54a、两个第二支臂58a)的运动平稳性,又能防止运动偏斜导致零部件的磨损或产生卡顿。
继续参阅图4和图5,联动机构50还可以包括两个第三支臂54b,两个第三支臂54b大致呈直杆状,且两个第三支臂54b的长度可以相等,第三支臂54b的长度也可以与第一支臂54a的长度相等。其中一个第三支臂54b转动连接于第一支架51a以实现与第一壳体12的联动,另一个第三支臂54b转动连接于第二支架51b以实现与第二壳体14的联动。两个第三支臂54b与两个第一支臂54a一一对应,且相互对应的第一支臂54a与第三支臂54b平行且间隔地设于第一连接件55的同侧。在第二壳体14相对第一壳体12滑动的过程中,第二壳体14带动两个第三支臂54b摆动。
在第二壳体14相对第一壳体12滑动以带动柔性显示屏20进出壳组件10的过程中,在第二壳体14相对远离第一壳体12时,第二壳体14可通过第二支架51b拉动与第二支架51b连接的第三支臂54b,并通过第一连接件55带动另一第三支臂54b同步摆动;在第二壳体14相对靠近第一壳体12时,第二壳体14可通过第二支架51b推动与第二支架51b连接的第三支臂54b,并通过第一连接件55带动另一第三支臂54b同步摆动。
在第二壳体14相对第一壳体12的移动方向上,第一连接件55与第二支架51b及连接于两者之间的第一支臂54a、第三支臂54b可以共同形成平行四边形机构,第一连接件55与第一支架51a及连接于两者之间的第一支臂54a、第三支臂54b可以共同形成另一平行四边形机构,以在第二壳体14相对第一壳体12的滑动过程中实现第一连接件55的平移,即使得第一连接件55与第一支架51a或者第二支架51b保持平行,从而提升第一支架51a、第二支架51b移动的平稳性。而且,结合图4,在第二位置时,第一连接件55的相对两侧的第一支臂54a、第三支臂54b可以折叠于第一连接件55,以缩减联动机构50的占用空间,提升电子设备100内部结构的紧凑性。
在一些实施方式中,联动机构50还可以包括两个第四支臂58b,两个第四支臂58b大致呈直杆状,且两个第四支臂58b的长度可以相等,第四支臂58b的长度也可以与第二支臂58a的长度相等。其中一个第四支臂58b转动连接于第一支架51a,另一个第四支臂58b转动连接于第二支架51b。两个第四支臂58b与两个第二支臂58a一一对应,且相互对应的第四支臂58b与第二支臂58a平行且间隔地设于第二连接件57的同侧。在第二壳 体14相对第一壳体12滑动的过程中,第二壳体14带动两个第四支臂58b摆动。
在第二壳体14相对第一壳体12滑动以带动柔性显示屏20进出壳组件10的过程中,在第二壳体14相对远离第一壳体12时,第二壳体14可通过第二支架51b拉动与第二支架51b连接的第四支臂58b,并通过第二连接件57带动另一第四支臂58b同步摆动;在第二壳体14相对靠近第一壳体12时,第二壳体14可通过第二支架51b推动与第二支架51b连接的第四支臂58b,并通过第二连接件57带动另一第四支臂58b同步摆动。
在第二壳体14相对第一壳体12的移动方向上,第二连接件57与第二支架51b及连接于两者之间的第二支臂58a、第四支臂58b可以共同形成平行四边形机构,第二连接件57与第一支架51a及连接于两者之间的第二支臂58a、第四支臂58b可以共同形成另一平行四边形机构,以在第二壳体14相对第一壳体12的滑动过程中实现第二连接件57的平移,即使得第二连接件57与第一支架51a或者第二支架51b保持平行,从而提升第一支架51a、第二支架51b移动的平稳性。而且,在第二位置时,第二连接件57的相对两侧的第二支臂58a、第四支臂58b可以折叠于第二连接件57,以缩减联动机构50的占用空间,提升电子设备100内部结构的紧凑性。
相关技术中,柔性显示屏20伸缩的电子设备100的滑动机构一般采用平行滑轨或梳齿式滑轨结构。一方面,滑动机构一般布局在壳组件10的内部,并需要与其他零部件例如电路板、电池等隔开。这种结构设置对电路板的布局产生了不利影响,降低了电子设备100内部空间的利用率。本方案的联动机构50可布局在壳组件10外部例如设置在展开状态的柔性显示屏20与壳组件10之间,因此可以不占用内部空间,有利于电路板的布局,并可提高内部空间的利用率。
另一方面,相关技术中,为保证第二壳体14与第一壳体12的相对滑动稳定性,需要在第二壳体14或者第二支架51b的整个行程中设置定位约束,定位约束的长度相对较长,占用空间大,且易受间隙影响,导致结构精度较差,因此这种结构设置的限制也较多。本方案的通过联动机构50的第一支臂54a、第二支臂58a、第一轮52a、第二轮52b、第三轮56a以及第四轮56b,可以实现第二支架51b相对第一支架51a的平稳移动,第二壳体14相对第一壳体12的滑动不易出现偏移,因此能保证柔性显示屏20伸缩过程中的运动稳定性及可靠性。
参阅图5,在一些实施方式中,在垂直于第二壳体14相对第一壳体12的移动方向上,第三支臂54b、第四支臂58b设置于驱动件53的相对的两侧,且第三支臂54b、第四支臂58b位于第一支臂54a、第二支臂58a之间。在第二壳体14相对第一壳体12滑动的过程中,连接于第一支架51a的第三支臂54b相对第一支架51a的转动方向、与连接于第一支架51a的第四支臂58b相对第一支架51a的转动方向相反。例如,在图4所示实施例中,在第二支架51b相对远离第一支架51a时,连接于第一支架51a的第三支臂54b相对第一支架51a的转动方向为逆时针,连接于第一支架51a的第四支臂58b相对第一支架51a的转动方向为顺时针。在图5所示实施方式中,在第二支架51b相对靠近第一支架51a时,连接于第一支架51a的第三支臂54b相对第一支架51a的转动方向为逆时针,连接于第一支架51a的第四支臂58b相对第一支架51a的转动方向为顺时针。这种设置可以实现更好地力平衡效果,使得连接于第一支架51a的第三支臂54b对第一支架51a的作用力,与连接于第一支架51a的第四支臂58b对第一支架51a的作用力,在垂直于第二壳体14相对第一壳体12的移动方向上的分力相抵消,进而保证第二支架51b相对第一支架51a的运动平稳性,并保证第二壳体14相对第一壳体12的滑动平稳性。连接于第二支架51b的第三支臂54b相对第二支架51b的转动方向,与连接于第二支架51b的第四支臂58b相对第二支架51b的转动方向相反的设置,可以起到类似的效果,此处不再赘述。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛 盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对申请专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干变形和改进,这些都属于本申请的保护范围。因此,本申请专利的保护范围应以所附权利要求为准。
