参考图1、图2和图3,在一实施例中,折叠式移动终端10为智能手机。在其他实施方式中,折叠式移动终端10也可以为平板等。同时参考图4,折叠式移动终端10包括壳体100、柔性屏200、折叠机构300和安装座400。壳体100包括第一壳组件110和第二壳组件120,第一壳组件110和第二壳组件120内设置有安装空间,安装空间用于安装折叠式移动终端10的电池、主板、处理器等电子元器件。第一壳组件110和第二壳组件120还可对柔性屏200、折叠机构300和安装座400及折叠式移动终端10的其他电子元器件起到支撑作用。参考图4,第一壳组件110开设有安装槽130,安装槽130贯穿第一壳组件110。同时参考图5和图6,壳体100包括限位柱140,限位柱140位于安装槽130。柔性屏200连接于第一壳组件110和第二壳组件120,柔性屏200具有可弯折显示的特性,其可用于显示信息并为用户提供交互界面。折叠机构300连接于第一壳组件110和第二壳组件120之间,第一壳组件110能够通过折叠机构300相对第二壳组件120转动,以带动 柔性屏200折叠和展开。参考图7,在一实施例中,当折叠式移动终端10折叠时,柔性屏200外露于壳体100。参考图1和图2,折叠式移动终端10处于展开状态,折叠式移动终端10具有大屏显示的效果。参考图7,折叠式移动终端10处于折叠状态,柔性屏200产生折叠,且柔性屏200外露于壳体100,在折叠状态时用户也可正常使用折叠式移动终端10。可以理解的是,作为另一种可实施方式,当折叠式移动终端10折叠时,柔性屏200可以隐藏于壳体100,以使柔性屏200不外露。
参考图4、图5和图6,第一壳组件110包括第一前壳111和第一后壳113,第二壳组件120包括第二前壳121和第二后壳123,第一前壳111位于第一后壳113和柔性屏200之间,第二前壳121位于第二后壳123和柔性屏200之间,柔性屏200连接于第一前壳111和第二前壳121。具体地,柔性屏200可以采用点胶的方式连接于第一前壳111和第二前壳121,以实现柔性屏200与壳体100的可靠连接。折叠机构300连接于第一前壳111和第二前壳121,第一前壳111和第一后壳113之间、第二前壳121与第二后壳123之间分别形成了用于安装电池、主板等电子元器件的安装空间。限位柱140连接于第一前壳111和第一后壳113中的至少一个,且安装槽130贯穿第一后壳113。
参考图8和图9,在一实施例中,折叠机构300包括折叠组件310和滑动组件320,滑动组件320包括第一滑块321、第二滑块323、第一支架325和第二支架327,折叠组件310包括轴套311、第一转轴312、第二转轴313、第一转接块314、第二转接块315、第一连杆316和第二连杆317。第一转轴312连接于第一滑块321,第二转轴313连接于第二滑块323,轴套311套设于第一转轴312和第二转轴313。第一连杆316连接于第一转接块314和第一前壳111,第二连杆317连接于第二转接块315和第二前壳121。第一转接块314套设于第一转轴312,第二转接块315套设于第二转轴313。第一支架325连接于第一滑块321并盖设于第一连杆316,第二支架327连接于第二滑块323并盖设于第二连杆317。第一滑块321至少部分收容于第一前壳111和第一后壳113之间,第二滑块323至少部分收容于第二前壳121和第二后壳123之间。
参考图1,以折叠式移动终端10的长度方向为x轴、宽度方向为y轴、厚度方向为z轴建立坐标系。在折叠式移动终端10折叠的过程中,第一壳组件110通过第一连杆316、第一滑块321带动第一转接块314相对第一转轴312转动,第一转接块314相对第一转轴312滑动以使第一连杆316在折叠式移动终端10的长度方向(x轴方向)的投影长度缩短,第一滑块321在第一后壳113上滑动并滑入第一壳组件110内;第二壳组件120通过第二连杆317、第二滑块323带动第二转接块315相对第二转轴313转动,第二转接块315相对第二转轴313滑动以使第二连杆317在折叠式移动终端10的长度方向的投影长度缩短,第二滑块323在第二后壳123上滑动并滑入第二壳组件120内。在折叠式移动终端10的长度方向上,第一后壳113与第二后壳123的间距缩短,折叠式移动终端10就能顺利折叠。在折叠式移动终端10展开的过程中,第一壳组件110通过第一连杆316、第一滑块321带动第一转接块314相对第一转轴312转动,第一转接块314相对第一转轴312滑动以使第一连杆316在折叠式移动终端10的长度方向(x轴方向)的投影长度增加,第一滑块321在第一后壳113上滑动并从第一壳组件110内滑出;第二壳组件120通过第二连杆317、第二滑块323带动第二转接块315相对第二转轴313转动,第二转接块315相对第二转轴313滑动以使第二连杆317在折叠式移动终端10的长度方向的投影长度增加,第二滑块323在第二后壳123上滑动并从第二壳组件120内滑出。第一后壳113与第二后壳123的间距增大,折叠式移动终端10就能顺利展开。在一实施例中,第一壳组件110与第二壳组件120在外观上轴对称地分布于折叠机构300的中轴线的两侧,以使得折叠式移动终端10能够对半展开或合拢,以增强折叠式移动终端10的美观性和实用性。
参考图10、图11和图12,安装座400大致呈矩形块状,其包括相背设置的前端面411、后端面413,及连接于前端面411、后端面413之间的侧端面415。安装座400包括 第一摄像头模组420,第一摄像头模组420具有第一入光面421,第一入光面421外露于前端面411所在一侧,环境光线能够穿过第一入光面421并入射至第一摄像头模组420的感光元件上。同时参考图13和图14,安装座400开设有弧形槽430,弧形槽430贯穿前端面411和后端面413中的至少一个,且弧形槽430位于侧端面415所围设的区域内。限位柱140穿设于弧形槽430,安装座400能够通过弧形槽430与限位柱140的滑动配合在安装槽130内转动至第一位置和第二位置。再参考图1,在第一位置时第一入光面421隐藏于壳体100。参考图10,在第二位置时第一入光面421外露于壳体100。上述折叠式移动终端10,第一摄像头模组420在第二位置时可以执行前置摄像头的功能,例如,用户可通过第一摄像头模组420进行自拍、视频通话等操作。上述结构可以避免前置摄像头占用柔性屏200所在一侧的面积,从而可以提升折叠式移动终端10的屏占比。例如,上述结构的移动终端10的屏占比可以在85%以上。
在图10所示实施例中,当折叠式移动终端10处于展开状态时,在第二位置时第一摄像头模组420外露于柔性屏200所在的一侧,第一摄像头模组420可以执行前置摄像头的功能。在图7所示实施例中,当折叠式移动终端10处于折叠状态时,在第二位置时由于壳体100两相背设置的侧面上均有柔性屏200,第一摄像头模组420既可用于执行前置摄像头的功能,也可用于执行后置摄像头的功能。进一步,参考图10,在一实施例中,安装座400可以包括受话器和补光灯,受话器可用于接听语音信息。补光灯可以为LED灯,补光灯可在用户自拍时进行补光,以获得更好的拍照效果。在第一位置时补光灯的出光面隐藏于壳体100,在第二位置时补光灯的出光面外露于壳体100。上述设置,受话器和补光灯无需占用柔性屏200所在一侧的面积,因此可以提升折叠式移动终端10内的屏占比,此处不再赘述。
参考图12,折叠式移动终端10可以包括设于安装座400的第二摄像头模组440,第二摄像头模组440具有第二入光面441,第二入光面441外露于后端面413。在第一位置时第二入光面441隐藏于壳体100,在第二位置时第二入光面441外露于壳体100。当折叠式移动终端10处于展开状态时,在第二位置时第二摄像头模组440外露于背向柔性屏200的一侧,第二摄像头模组440可以执行后置摄像头的功能。例如,用户可以通过第二摄像头模组440进行远景拍摄、视频录制等操作。可以理解的是,第二摄像头模组440不是必须的,因而可以省略。
参考图5和图6,在一实施例中,侧端面415包括相背设置的左端面412、右端面414,和相背设置的顶端面416、底端面418,左端面412、右端面414位于顶端面416、底端面418之间,顶端面416、底端面418位于左端面412、右端面414之间,弧形槽430位于左端面412、顶端面416、右端面414和底端面418所围设的区域内。在第一位置时顶端面416与第一后壳113的顶面平齐,在第二位置时顶端面416与第一后壳113的顶面错位。上述结构的折叠式移动终端10,安装座400位于第一位置时折叠式移动终端10具有较高的外观整体性。
进一步,参考图5和图6,作垂直于终端设备的厚度方向(z轴方向)的几何平面,并以该几何平面为基准平面。弧形槽430的槽壁在基准平面上的正投影为圆弧形。安装座400的转动轴线与安装座400的侧端面415相切,且安装座400的转动轴线穿过弧形槽430的槽壁在基准平面上的正投影的圆心。上述折叠式移动终端10,由于弧形槽430位于安装座400的侧端面415围设的区域内,弧形槽430的圆心可以位于安装座400的侧端面415上。安装座400能够通过弧形槽430相对限位柱140滑动以转动至第一位置和第二位置,当限位柱140在弧形槽430内滑动时,安装座400可以以弧形槽430的圆心为转动中心转动,第一壳组件110上对应转动中心所在的位置处无需设置避让空间以避免机构产生干涉,因此间隙可以做得极小,有利于提升折叠式移动终端10的外观整体性。由于限位柱140穿设于弧形槽430内,限位柱140利用了安装座400的厚度,因而有利于折叠式移 动终端10的轻薄化。
参考图5和图6,在安装座400呈矩形块状的实施例中,顶端面416与左端面412的交线形成第一侧棱,顶端面416与右端面414的交线形成第二侧棱,在第一位置时第一侧棱和第二侧棱外露于第一壳组件110的顶面,且第一侧棱穿过弧形槽430的槽壁在基准平面上的正投影的圆心。上述设置,安装座400以第一侧棱为转动轴线在第一位置和第二位置之间转动,安装槽130对应第一侧棱所在位置处的边缘与第一侧棱之间的间隙可以做得极小,从而提升折叠式移动终端10的外观整体性。
可以理解的是,安装座400的右端面414所朝向的安装槽130的槽壁可以加工为圆弧面,以使安装座400的对角线能够顺利从安装座400摆出,安装槽130的对应第二侧棱所在位置处的间隙也可以做得极小,从而使得折叠式移动终端10具有较高的外观整体性。进一步,右端面414在基准平面上的正投影可以为弧形,即将左端面412加工为弧面,且安装座400的转动轴线穿过右端面414在基准平面上的正投影的圆心。上述设置,安装座400与第一壳组件110之间的间隙可以做得极小,因此可以减小灰尘或水滴等异物进入折叠式终端设备内的概率,有利于折叠式终端设备的防水防尘。
进一步,参考图13和图14,第一摄像头模组420包括图像传感器423,图像传感器423可以为CCD(电荷耦合器件)或者CMOS(互补金属氧化物半导体)。图像传感器423在基准平面上的正投影为矩形状。例如,图像传感器423在基准平面上的正投影可以为正方形或者长方形。参考图14,在第二位置时图像传感器423在基准平面上的正投影具有距离第一壳组件110的顶面较近的侧边,且侧边与折叠式移动终端10的长度方向(x轴方向)平行。参考图13,在第一位置时,图像传感器423在基准平面上的正投影的侧边与折叠式移动终端10的长度方向(x轴方向)倾斜设置。上述设置,相比于前置摄像头直接固定连接在折叠式移动终端10的方案,在第二位置时第一摄像头模组420的图像传感器423的姿态没有变化,因此无需对第一摄像头模组420的成像的算法进行大的调整,因而可以节省折叠式移动终端10的开发成本。
参考图13和图14,折叠式移动终端10可以包括驱动机构500,驱动机构500包括动力件510和推杆520,动力件510与第一壳组件110连接,动力件510能够驱动推杆520沿折叠式移动终端10的宽度方向(y轴方向)移动,以推动安装座400由第一位置转动至第二位置。进一步,在一实施例中,动力件510为电机。驱动机构500包括第一齿轮530、第二齿轮540、丝杆550和滚动件560,第一齿轮530与动力件510连接,第二齿轮540与第一齿轮530啮合,丝杆550与第二齿轮540连接,丝杆550上开设有螺旋槽,滚动件560与推杆520转动连接,且滚动件560可滚动地设于螺旋槽内,推杆520与安装座400滑动连接,动力件510能够驱动第一齿轮530转动,第一齿轮530能够通过第二齿轮540带动丝杆550转动,丝杆550能够带动推杆520沿折叠式移动终端10的宽度方向移动,以使安装座400由第一位置转动至第二位置。驱动机构500的设置,有利于安装座400运动的电动化以提升用户使用的便利性。例如,可以在折叠式移动终端10设置实体按键,通过实体按键控制动力件510的通电和断电,从而实现安装座400运动的电动化。又如,可以在折叠式移动终端10设置虚拟按键,通过虚拟按键控制动力件510的通电和断电,从而实现安装座400运动的电动化,此处不在赘述。
作为一种可实施方式,安装座400由第一位置推动至第二位置后,可以采用手动的方式将安装座400从第二位置推回至第一位置。参考图14,作为另一种可实施方式,折叠式移动终端10可以包括弹性回位件460,弹性回位件460的一端连接安装座400,另一端连接第一壳组件110,弹性回位件460能够带动安装座400由第二位置转动至第一位置。弹性回位件460可以为弹簧或者弹性柱等,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发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
