Description

另外，目前的手机游戏分为横屏游戏和竖屏游戏，带全键盘的上翻机型在竖屏游戏中游戏体验比较好；而带全键盘的侧翻机型在横屏游戏中游戏体验比较好；然而，目前并没有一种方案能够使得用户在玩需要键盘的横屏游戏和竖屏游戏时都能够带来好的游戏体验。

需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在本实施例中提供了一种移动终端，图1是根据本发明实施例的移动终端的结构示意图，如图1所示，该移动终端包括：第一主体12和第二主体13，以及连接第一主体12和第二主体13的转轴结构14，其中，
转轴结构14的第一转向部件与第一主体12的第一角连接，其中，第一转向部件设置为 使得第一主体12以第一角为中心转动。
通过上述结构，第一主体和第二主体通过在第一角处以转轴结构连接的方式，使得第一主体可以以第一角为中心转动，从而实现了第一主体的多角度旋转，解决了折叠式移动终端的键盘和屏幕之间无法实现多角度转动导致用户体验差的问题，提升了用户体验。
可选地，转轴结构还包括第二转向部件，第二转向部件与第二主体的第二角连接，其中，第二转向部件设置为使得第二主体以第二角为中心转动。
可选的，上述的第一主体和第二主体可以是移动终端的屏幕和键盘中的一个和另一个。较优地，键盘可以是全键盘，也可以是非全键盘；第一主体和第二主体的形状为长方体，且第一主体和第二主体的长相等、宽相等；高度可以不同也可以相同。
可选地，第一转向部件可以为球型转轴，例如：第一转向部件包括具有第一开口的第一外球转体和位于第一外球转体形成的空腔内的第一内球转体；其中，第一开口小于第一内球转体的直径，从而使得第一内球转体不能够从空腔中脱离，另外，第一开口还限制第一内球转体的转动范围。
第二转向部件也可以为球型转轴，例如，第二转向部件包括具有第二开口的第二外球转体和位于第二外球转体形成的空腔内的第二内球转体；其中，第二开口小于第二内球转体的直径，从而使得第二内球转体不能够从空腔中脱离，另外，第二开口还限制第二内球转体的转动范围。
其中，第一外球转体或者第一内球转体中的一个转体与第一主体连接，第一外球转体或者第一内球转体中的另一个转体与第二外球转体或者第二内球转体中的一个转体连接，第二外球转体或者第二内球转体中的另一个转体与第二主体连接。即两个球型转轴的连接方式可以是多种的，可以内球转体与内球转体连接，也可以外球转体与外球转体连接，或者可以是外球转体和内球转体连接。
另外，第一开口和第二开口的切口方向可以不是水平切口，而是具有一定角度的斜向切口，较优地，第一开口的切口平面与旋转杆呈第一预设夹角；第二开口的切口平面与旋转杆呈第二预设夹角。这个斜向切口可以达到下列效果：假设在一个转向部件中，外球转体(以外球转体为例，或者内球转体)在垂直方向放置，则内球转体(或者外球转体)可以转动到垂直方向，并可以使得内球转体(或者外球转体)向水平方向旋转的角度最大(即内球转体与水平方向的夹角达到最小)。在这种情况下，第一外球转体或者第一内球转体中的另一个转体通过旋转杆与第二外球转体或者第二内球转体中的一个转体连接。
可选地，旋转杆包括：与第一外球转体或者第一内球转体中的另一个转体连接的第一柱状转体，和与第二外球转体或者第二内球转体中的一个转体连接的第二柱状转体，第一柱状转体套接在第二柱状转体外，以使第一柱状转体和第二柱状转体沿旋转杆的中心轴线旋转。这样可以使得第一转向部件和第二转向部件分别具有最大的旋转角度，进而使得转轴结构具有更广阔的旋转角度。
可选地，为了适应移动终端的旋转对第一主体和第二主体之间的距离变化，旋转杆支持沿中心轴线方向的长度伸缩。
可选地，第一柱状转体的内壁上设有环状台阶，第二柱状转体的外壁上设有环状台阶或者凸点，以限制旋转杆的最大拉伸长度；或者第一柱状转体的内壁上设有凸点，第二柱状转体的外壁上设有环状台阶，以限制旋转杆的最大拉伸长度；或者第一柱状转体的内壁上设有多个第一凸点，第二柱状转体的外壁上设有多个第二凸点，多个第一凸点之间的距离小于第二凸点的宽度或者多个第二凸点之间的距离小于第一凸点的宽度，以限制旋转杆的最大拉伸长度。通过该方式，可以避免由于过度拉伸导致旋转杆的第一柱状转体和第二柱状转体的分离。
例如，环状台阶可以是连续的台阶，也可以是由具有一定间隔的多个凸点构成的不连续的台阶。并且，第一柱状转体的内壁上凸点之间的间隔小于第二柱状转体的外壁上凸点的宽度；和/或第一柱状转体的内壁上凸点的宽度大于第二柱状转体外壁上凸点之间的间隔。
可选地，第一内球转体的球体的外径比第一外球转体的球体的内径小0.04毫米至0.06毫米；第二内球转体的球体的外径比第二外球转体的球体的内径小0.04毫米至0.06毫米。
可选地，第一角设置有连接并容纳第一转向部件的第一凹槽；第二角设置有连接并容纳第二转向部件的第二凹槽。通过第一凹槽和第二凹槽，可以使得转轴结构嵌入第一角和第二角中，从而节约了空间，减小了移动终端的体积。
可选地，转轴结构为实心结构或者空心结构。
例如，转轴结构为空心结构，第一主体或者第二主体中设置有储能电源，第一主体和第二主体通过穿过转轴结构的空心结构的供电线和数据线实现电连接。
或者，第一主体和第二主体中分别设置有储能电源和无线数据收发器，通过无线数据收发器可以实现第一主体和第二主体之间的数据通信。
可选地，移动终端还包括：限位结构，其中，当转轴结构转动到预定位置，使得第一角的第一边与第二角的第二边相邻接的情况下，限位结构设置为铰接第一主体的第三边和第二主体的第四边，以使第一主体和第二主体在转轴结构和限位结构的限制下仅能沿第一边或者第二边为翻转轴翻转；其中，第三边为与第一角除第一边之外的另一条边相对的一条边，第四边为与第二角除第二边之外的另一条边相对的一条边。
上述的限位结构设置为起辅助支撑的作用，例如，在移动终端通过转轴结构的旋转，要实现上翻时，限位结构设置为支持上翻的限位；在移动终端通过转轴结构的旋转，要实现侧翻时，限位结构设置为支持侧翻的限位。限位结构可以采用铰链式连接装置实现，也可以通过在移动终端的侧边上增加可以相互吸合的材料来实现：例如，在第一主体的侧边和第二主体的侧边中增加磁体，使得两条侧边靠近后相互吸合，从而实现限位的功能，配合转轴结构实现折叠式移动终端的上翻或者侧翻。
可选地，以限位结构采用铰链式连接装置为例，限位结构包括：第一铰接端、第二铰接端和连接第一铰接端和第二铰接端的连接杆，其中，第一铰接端通过固定的铰链结构与第三边铰接，第二铰接端包括一个凸起结构；凸起结构设置为嵌入第四边上与凸起结构适配的第一凹槽结构，以实现可拆卸的铰链连接。
可选地，凸起结构由弹性材料制成，第一凹槽结构为开口且凸起结构大于第一凹槽结构的开口，设置为嵌入第四边上与凸起结构适配的凹槽结构，以实现可拆卸的铰链连接。
可选地，连接杆由具有弹性的刚性材料制成。
可选地，移动终端还包括：收纳结构，其中，收纳结构为第三边上的第二凹槽结构，第二凹槽结构的形状与限位结构相同，以使限位结构绕第一铰接端转动至预设位置时限位结构被收纳至收纳结构中。通过该方式，减少了移动终端的体积。
本实施例还提供了一种转轴结构，转轴结构的第一转向部件与移动终端的第一主体的第一角和移动终端的第二主体连接，其中，第一转向部件设置为使得第一主体以第一角为中心转动。
可选地，转轴结构还包括第二转向部件，其中，第二转向部件与移动终端的第二主体的第二角连接，第二转向部件设置为使得第二主体以第二角为中心转动。

为了使本发明实施例的描述更加清楚，下面结合优选实施例进行描述和说明。
本发明优选实施例提供了一种屏幕可多角度旋转的双屏终端产品，包含主旋转轴设计、双屏幕的多角度旋转可以实现多角度的拍照(不仅限与拍照，还包括媒体播放等其他功能)、全键盘终端产品主机(相当于第一主体)和屏幕(相当于第二主体)配合可使终端产品很快的变为侧翻(或上翻)全键盘终端产品，增加终端产品游戏的键盘快感等三个方面。
其中，主旋转轴采用可伸缩式的双球形连接器(相当于上述转轴结构)设计思想，其中双球形设计可以使终端产品实现多角度的旋转，主旋转轴的伸缩功能主要为了解决主旋转轴与辅旋转轴配合形成上翻和侧翻产品时主旋转轴长度的问题，其主旋转轴的可以采用空心设计也可以采用实心设计，采用空心设计时可将屏幕的供电与数据线放置在空心部分以实现数据的传输，采用实心设计时实心部分可采用超导材料对屏幕进行供电和数据传输，另外屏幕与主机之间也可通过无线信号进行供电和数据传输。
主旋转轴定义及构造介绍
主旋转轴14即终端产品进行多角度旋转所依赖的主要旋转轴，该轴采用双球形设计思想和伸缩杆原理满足产品的多角度旋转和旋转轴杆长度的调节，进而可以满足各种情况下旋转的轴长需求。图2是根据本发明优选实施例的主旋转轴的局部剖面图，如图2所示，主旋转轴14包括五部分，即图2中的外球伸缩杆一1、外球伸缩杆二2、内球连接杆一3、内球连接杆二4、供电与数据传输线5等五部分组成。其中内球连接杆一3和屏幕(或终端产品主机)部分13连接，内球连接杆二4和终端产品主机(或屏幕)部分12连接。

主旋转轴14在设计时外球伸缩杆一1的球体部分与内球连接杆一3的球体部分有一定的空隙(参考图4主旋转轴局部放大效果图)，较优的空隙为0.04mm-0.06mm，并在两个球体的缝隙之间可以增加可提高转动的润滑物质，同时保证两球体的表面平整度，这样可以避免两球体直接接触对主轴的损坏，同时也可使主轴转14的更加的轻松方便。
主旋转轴伸缩的实现
图5是根据本发明优选实施例的主旋转轴伸缩前后局部放大对比图；图6是根据本发明优选实施例的主旋转轴伸缩后的局部放大效果图，其中，图5和图6中的1均为外球伸缩杆一；图5和图6中的2均为外球伸缩杆二。
主旋转轴14的伸缩功能是图5中的外球伸缩杆一1和外球伸缩杆二2进行伸缩。
为保证主旋转轴14在伸缩过程中主旋转轴14不给拉开，因此在设计主轴连杆是在外球伸缩杆一1和外球伸缩杆二2上分别设置了一个小的环形台阶或一些小的凸点以保证主旋转轴14在伸缩时不被拉开，参见图6主旋转轴伸缩后的局部放大效果图。
对于外球伸缩杆一1则要求其内壁平整度较好，对于外球伸缩杆二2则要求其外壁平整度较好，且在外球伸缩杆一1和外球伸缩杆二2之间的缝隙内可以增加可提高拉伸效果的润滑物质。
辅旋转轴设计实现
辅旋转轴(相当于限位结构)连接杆10&11即为了配合主旋转轴14使产品变为上翻或侧翻产品而设计的，其作用是与是与主旋转轴14形成上翻或侧翻的类似于转轴的部件(也可称为上翻转轴或侧翻转轴)。
图7是根据本发明优选实施例的辅旋转轴组件分解图；图8是根据本发明优选实施例的辅旋转轴连接杆的结构示意图。辅旋转轴主要由三部分组成，即图7中所指示的主机上面的辅旋转轴放置空间部分8&9、辅旋转轴连接杆10&11(参见图8辅旋转轴连接杆)和屏幕上面的辅旋转轴转动连接孔部分6&7，其中，辅旋转轴连接杆10&11采用高弹性的刚性材料，如弹性较好的塑料、钢片、合成材料等，较优地为高弹性的塑钢材料。
其中，辅旋转轴连接杆10&11依靠连接杆两端的小圆球连接屏幕和主机，且在与主机部分12连接的小圆球与连接杆的连接借助于一小截圆柱进行连接(参见图8辅旋转轴连接杆)，且与主机部分12连接的小圆球直径略大于主机部分12连接孔的开孔直径，这样可以使辅旋转轴连接杆10&11不会掉落丢失。
主旋转轴与辅旋转轴配合形成上翻或侧翻产品的实现
图9是根据本发明优选实施例的主旋转轴与辅旋转轴配合形成的上翻产品效果图；图10是根据本发明优选实施例的主旋转轴与辅旋转轴配合形成的侧翻产品效果图。
本实例主要采用主旋转轴14和辅旋转轴连接杆10&11进行配合，并连接终端产品的主机部分12和屏幕部分13，形成上翻和侧翻旋转轴从而使产品变为上翻或侧翻产品，具体实现效果参考图9；其中，图9和图10中的12均为主机部分，图9和图10中的13均为屏幕部分，图9和图10中的14均为主旋转轴，图9和图10中的10为上翻辅旋转轴连接杆，图9和图10中的11为侧翻辅旋转轴连接杆。
上翻产品的实现是借助于图9中的主旋转轴14与上翻辅旋转轴连接杆10连接终端产品的主机部分12和屏幕部分13，从而在图9中的主机部分12和屏幕部分13之间形成了一个上翻旋转轴，从而使得产品可以方便的变为上翻产品。
侧翻产品的实现借助于图10中的主旋转轴14与侧翻辅旋转轴连接杆11连接终端产品的主机部分12和屏幕部分13，从而在图10中的主机部分12和屏幕部分13之间形成了一个侧 翻旋转轴，从而使得产品可以方便的变为侧翻产品。
多角度旋转的实现
图11是根据本发明优选实施例的多角度旋转效果及局部放大图。本实例仅采用主旋转轴进行多角度旋转，无需与辅旋转轴进行配合，实现效果参考图11。其中，图11中的12是主机部分，图11中的13是屏幕部分，图11中的14是主旋转轴。
本实例中的主机部分12与屏幕部分13通过主旋转轴14连接，并同时主旋转轴采用的双球形设计可以实现多角度旋转的问题。
应用场景实施例
用户在进行拍照的时候，则可以将手机转化为上翻或侧翻手机，利用像素比较高的后置摄像头和外屏幕进行自拍，同时也可在屏幕上点击进行拍照，避免用户为了获取像素较高的照片而采用后置摄像头拍照的点击和拍照过程中的预览问题。
或者，用户在玩游戏的时候则可将终端类产品转化为侧翻产品，将产品放置在桌面上使用两个手玩游戏，增强了玩游戏的手感，也避免了单手玩游戏的操作动作比较慢的情况。
该发明实施例采用的多角度主旋转轴使终端产品实现了多角度的旋转，可以完成任意角度的拍照功能，同时也克服了传统上翻手机和侧翻手机的局限性，将多个产品的优越性集中在一个产品上进行实现，很大程度的方便了用户的使用，提供用户体验效果。
