Description

一种移动终端、控制系统和控制方法 技术领域
本公开涉及移动终端技术领域，更具体地，涉及一种移动终端、控制系统和控制方法。
背景技术
目前，大部分移动终端如智能手机的造型还是以直板为主，屏幕小点的智能手机，比如5寸左右的智能手机，方便携带，但是屏幕尺寸较小，无法满足人们日益增长的影音娱乐及其他多元化的需求；屏幕大点的智能手机，比如6寸屏甚至更大屏幕的智能手机，屏幕尺寸增加，用户体验更好，但整机尺寸大，携带不方便，而且人们也不是任何时候都需要使用大屏幕。
最近几年，柔性屏越来越多的出现在人们的视线中，柔性屏以其可以弯曲的特性，被设计人员越来越多的采用。但绝大部分使用柔性屏来进行屏幕扩展的技术方案，均是将柔性屏通过固定在两个手机壳体上，然后用不同的方式连接两个手机壳体，需要使用大屏模式的时候将两个连接的壳体展平，需要使用小屏模式的时候将两个壳体闭合。
这些方案与翻盖机类似，实际上是用“转轴”将两个屏幕连接起来而已，需要使用大屏幕的时候将翻盖打开即可。这些方案的核心都在于两个手机壳体中间的连接部分的设计，但其对柔性屏弯曲特性的使用，也局限于手机壳体中间部位的弯曲部分。在手机的壳体上，柔性屏实际和普通屏幕的作用是一样的，使得柔性屏弯曲特性的使用大打折扣，优势无法完全发挥。此外，这些方案的屏幕扩展不够自由。由于技术原理和翻盖机的原理非常相似，所以屏幕实际上只有单屏和双屏两个状态。人们无法根据自己的喜好，来自由设置屏幕的大小。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白，下文中将结合附图对本公开的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
实施例一：
如图1-图20所示，本实施例提供了一种移动终端，包括壳体和柔性屏2，柔性屏2包括固定在壳体上的固定部分20和可相对于壳体运动的扩展部分21。
移动终端还包括运动机构，运动机构能带动扩展部分21运动以使扩展部分21的至少一部分运动至壳体外，此时壳体外朝上的扩展部分21与固定部分20组成移动终端的显示屏，移动终端处于宽屏模式；并且运动机构还能带动扩展部分21反向运动以使处于壳体外的扩展部分21收回壳体内，此时固定部分20组成移动终端的显示屏，移动终端处于窄屏模式。
具体地，柔性屏2的结构如图4所示，其中矩形框内的部分为固定部分20，矩形框外的部分为扩展部分21。
如图1-图3和图5、图6所示，壳体包括固定壳体1，当柔性屏2处于窄屏模式或宽屏模式时，柔性屏2的固定部分20始终固定在固定壳体1的上表面上。
柔性屏2的扩展部分21可相对于壳体运动，通过扩展部分21的扩展或收纳动作实现显示屏在宽屏与窄屏之间的切换。其中，如图1和图3所示，当柔性屏2处于窄屏模式，即扩展部分21处于收纳状态时，柔性屏2的扩展部分21隐藏在壳体内部，无法用于显示信息，仅柔性屏2的固定部分20用于显示信息，因此此时固定部分20构成显示屏；在需要对显示 屏进行扩展时，扩展部分21的至少一部分会在运动机构的带动下逐渐运动至壳体外部，如运动至平铺于与固定部分20相水平的位置，完成对柔性屏2的扩展，此时运动至壳体外朝上的扩展部分21与固定部分20均可用于显示信息，二者共同构成移动终端的显示屏，使移动终端处于宽屏模式。需要进行柔性屏2的收纳时，只需要运动机构带动柔性屏2的扩展部分21进行一次相反方向(与柔性屏2扩展时的运动方向相反)的运动即可。
本实施例中，当扩展部分21完全扩展时，显示屏可达到最大，当扩展部分21完全收纳时，显示屏可达到最小，显示屏最大时的宽度可为显示屏最小时的宽度的两倍。
本实施例的移动终端，通过运动机构带动柔性屏2的扩展部分21进行扩展和收纳动作，实现了移动终端在宽屏和窄屏之间的切换；且扩展部分21可进行连续的扩展，使显示屏可处于最大尺寸和最小尺寸之间的任意尺寸，能够满足用户在不同情况下对不同尺寸的显示屏的需求，提升了用户的使用体验。
移动终端还包括支撑结构，支撑结构至少用于支撑运动至壳体外的扩展部分21，以便支持用户在扩展部分21上进行触摸或者其他相应操作，而扩展部分21不会发生明显的变形，保证了柔性屏结构的可靠性和强度。
可选地，支撑结构包括能够变形的支撑机构，支撑机构与扩展部分21相固定并用于支撑扩展部分21，且支撑机构与运动机构相连接并能在运动机构的带动下运动。
支撑机构，一方面能够对扩展部分21进行支撑，以便在扩展部分21运动至壳体外后使用户能够在扩展部分21上进行触摸操作；另一方面还具有柔性，能够变形，因此在扩展部分21进行扩展或收纳运动时，与扩展部分21相固定的支撑机构能够随之运动变形，与扩展部分21一起进行扩展或收纳动作。
运动机构与支撑机构相连接，这样可通过带动支撑机构运动来带动扩展部分21运动。运动机构与支撑机构直接连接，而不是与扩展部分21直接连接，一方面动力结构与支撑机构的连接操作更加简便易实施，另一方面使得柔性屏2的拆卸方便，便于用户更换柔性屏2。
支撑机构即要具有支撑作用，同时整体要具体柔性，可有两种方式，一种是用刚性材料拼接；另一种是采用柔性材料，如皮带，柔性板等。
具体地，在本实施例中，支撑机构采用第一种方式实现，如图8和图10所示，支撑机构为类似履带式结构，包括多个支撑板条30，多个支撑板条30的长度方向垂直于支撑机构的运动方向，且多个支撑板条30依次活动连接使相邻的支撑板条能够相对运动(即相邻的支撑板条之间的连接结构使得相邻的支撑板条具有相对运动的)，这样支撑机构整体能够变形，以便在运动机构的带动下，支撑机构和柔性屏2的扩展部分21一起进行扩展和收纳动作。此外，支撑板条30具有一定的刚性，这样多个支撑板条30组成的支撑机构也具有一定刚性，能够对柔性屏2的扩展部分21进行支撑，以便在扩展部分21上进行操作。
其中，多个支撑板条30实现活动连接可以通过以下两种方式实现，一种是：多个支撑板条30之间依次铰接，以实现活动连接；另一种是：多个支撑板条30固定在一柔性支撑带上，利用柔性支撑带具有柔性、可变形的特性，实现固定在柔性支撑带上的多个支撑板条30可以相对运动，进而实现多个支撑板条30的活动连接。
应当理解，支撑机构也可以包括一个整体采用柔性材料制成的柔性支撑带或柔性支撑板，该柔性支撑带或柔性支撑板需要具有足够的支撑强度，以便能够支撑在扩展部分21上进行触屏操作。
可选地，支撑结构还包括滑动支撑部件，壳体包括固定壳体1，滑动支撑部件与固定壳体1通过滑动副滑动连接，并且滑动支撑部件与运动机构相连接并能在运动机构的带动下运动，支撑机构支撑在滑动支撑部件上。
在运动机构带动柔性屏2的扩展部分21和支撑机构进行扩展时，滑动支撑部件也在运动机构的带动下相对于固定壳体1发生滑动，并且滑动支撑部件的滑动动作与支撑机构的扩展动作相适配，以便滑动支撑部件对支撑机构进行支撑，进而便于支撑机构对扩展部分21进行支撑。
具体地，在本实施例中，如图9和图11所示，固定壳体1上固定连接有固定板10，固定板10上设有滑轨100；滑动支撑部件为滑动支撑板31，用刚性和强度较好的材料制成，以保证其结构可靠性，且滑动支撑板31上设有凸出的滑动部310，滑动部310与滑轨100滑动配合并构成滑动副，滑动支撑板31可相对于固定壳体1滑动。在柔性屏2扩展的时候，滑动支撑板31在固定板10中滑动到相应位置，以支撑展开的柔性屏的相关结构，如运动至壳体外的支撑机构可支撑在滑动支撑板31的上表面上(见图10)。
应当理解，也可以在固定板10上设置滑动部310，在滑动支撑板31上设置滑轨100。
为了防止滑动支撑板31滑动时与固定板10脱离，因此设置了防止滑动支撑板31滑脱的防脱结构。
可选地，如图12所示，防脱结构包括固定在固定壳体1上的第一防脱凸起101以及固定在滑动支撑板31上的第二防脱凸起311。
在滑动支撑板31滑动的过程中，第一防脱凸起101能够与第二防脱凸起311发生运动干涉，阻止滑动支撑板31继续滑动、与固定板10脱离。第一防脱凸起101能够与第二防脱凸起311对滑动支撑板21的滑动距离进行限制，使扩展部分在一个相对可靠的范围内进行扩展，既保证了柔性屏2能够进行扩展，同时又保证了扩展以后整个显示屏结构的稳定和可靠。
应当理解，还可以设置其他形式的防脱结构，如：将滑轨100一端的开口设置为封闭的，当滑动支撑板31滑动到与该封闭的端部相抵时，该封闭的端部阻止滑动支撑板31继续滑动、与固定板10脱离。
可选地，支撑结构上设有能够对柔性支撑板的运动进行导向的导向结构。这样在运动机构带动柔性支撑板运动时，导向结构使柔性支撑板和柔性屏2的扩展部分21沿特定的轨迹运动，使得柔性屏2的扩展部分21的扩展和收纳动作能够更顺畅地进行。
具体地，如图13所示，在本实施例中，滑动支撑板31上设有导轨312，导轨312整体大致呈跑道形，包括沿滑动支撑板31的滑动方向设置的两个导向段3120和将两个导向段3120连接的连接段3121，可选地，该连接段3121呈弧形。进一步，支撑机构上设有导向部，导向部与导轨312配合，以对支撑机构的运动进行导向，进而对固定在支撑机构上的扩展部 分21进行导向，使支撑机构和扩展部分21在限定的轨迹上运动。
应当理解，导轨312不限于包括两个导向段3120，还可以包括多于两个的导向段3120，连接段3121将多于两个的导向段3120依次连接；或者，导轨312还可以呈其他形状。
优选地，为了对支撑机构进行更好地支撑，可设置多个滑动支撑板31。具体地，如在本实施例中，柔性屏2的扩展部分21可在固定部分20的左侧进行扩展，支撑机构的支撑板条30沿着前后方向设置，故需设置前后两个滑动支撑板31分别对支撑板条30的前后两端进行支撑；进一步，在固定壳体1的前后两端均设置固定板10，以便与前后两个滑动支撑板31滑动连接，如图17所示。
可选地，壳体包括保护壳体32，保护壳体32包围在扩展部分21的至少一部分外，以对显示屏的扩展部分21进行保护，如用于在宽屏模式下对柔性屏的扩展部分21进行必要的保护，防止意外情况发生造成柔性屏的损伤。
具体地，在本实施例中，如图14、图17和图18所示，保护壳体32包括底板320、第一侧板321、第二侧板322和第三侧板323。其中，第一侧板321和第二侧板322分别与底板320的前后两端固定，并且第一侧板321和第二侧板322大致垂直于底板320，第一侧板321和第二侧板322沿滑动支撑板31的滑动方向设置；第三侧板323与底板320的左端相固定，且第三侧板323为具有弧度的弯板。
进一步，保护壳体32的前后两端分别与前后两个滑动支撑板31固定(如通过金属粘胶的方式固定)。具体地，底板320的前后两端可以分别与前后两个滑动支撑板31固定，和/或第一侧板321和第二侧板322可以分别与前后两个滑动支撑板31固定。
在宽屏模式和窄屏模式下，扩展部分21的左侧和背侧均隐藏在保护壳体32内，从而保护壳对扩展部分21起到相应的保护作用，同时保护壳的设置，使得整机的外观更美观。
可选地，运动机构包括动力源和传动机构，动力源安装在壳体或支撑结构上，动力源与传动机构连接并带动传动机构运动，传动机构与支撑结构连接并带动支撑结构运动。
具体地，在本实施例中，运动机构包括电机，电机安装在滑动支撑板31上并位于滑动支撑板31的内侧。通电后，电机转动，并带动传动机构运动，传动机构带动支撑机构和其上的扩展部分21进行扩展和收纳动作。
采用电机提供动力可以使柔性屏的扩展及收纳过程自动化，运动过程中的施力均匀化，不管是用户体验还是对柔性屏幕的寿命保护，都具有很明显的优势。
可选地，传动机构为链传动机构或皮带传动机构或者齿轮齿带传动机构。
具体地，在本实施例中，如图15和图16所示，动机构为链传动机构，其具体包括链轮41和链条43。其中，链轮41安装在滑动支撑板31上，链条43与链轮41啮合配合。
进一步，链条43包括交替设置的外链板431和内链板430、以及将外链板431和内链板430转动连接的销轴432。支撑机构的支撑板条30固定(如通过铆钉固定连接或者烧焊固定连接)在外链板431和内链板430上。
当柔性屏2的扩展部分21进行扩展时，电机带动链轮41转动，链轮41带动链条43运动，从而带动固定于链板上的支撑机构运动，支撑机构带动其上固定的扩展部分21进行扩 展运动；当柔性屏2的扩展部分21进行收纳时，电机反向转动，并带动链轮41反向转动，链轮41带动链条43反向运动，从而带动固定于链板上的支撑机构反向运动，支撑机构带动其上固定的扩展部分21反向进行收纳运动。
具体地，在本实施例中，如图16所示，链传动机构的销轴432的一端突出于外链板431和内链板430，销轴432的该突出部分可充当导向部，与滑动支撑板31上的导轨312配合，起到导向作用。导轨312为链传动机构中的销轴432提供运动限制，使销轴432在限定的轨迹上运动，使整个链传动机构的运动更加流畅和可靠，从而实现整个链传动机构中的核心——链条43的展开与收纳，进而带动支撑机构以及柔性屏2实现展开和收纳。需要说明的是，支撑机构的支撑板条30固定在链条43上并通过链条43实现了多个支撑板条30的柔性连接，因此可将链条43视为支撑机构的连接机构，故链条43的销轴432的突出部分充当导向部时，可视为在支撑机构上设置导向部。
应当理解，导向部不限于销轴432的突出部分，还可以为其他形式，如直接在支撑板条30设置导向部，或者在链传动机构上另设置导向部。
可选地，动力机构包括两个链传动机构，两个链传动机构的链轮41通过传动轴42连接。
具体地，如图15和图17所示，传动轴42的前后两端分别支撑在前后两个滑动支撑板31上，两个链传动机构一前一后设置，且两个链传动机构的链轮41分别安装在传动轴42的前后两端上；支撑机构的支撑板条30的前后两端分别固定在两个链传动机构的链条43上。
传动轴42的设置，保证了两个链轮41之间的转动保持同步，从而保证两个链条43同步运动，进而保证支撑机构及其上的扩展部分21的前后两端运动同步，防止因前后两根链条43之间发生明显的传动错位而导致扩展部分21发生扭曲不良。为了保证传动轴42能够在两个链轮41之间同步地传递运动，故需要使用较好的刚性材料制成。
需要说明的是，为了保证在操作显示屏时，扩展部分21不会因为左右的滑动操作而发生扩展或收纳操作，需对显示屏进行锁止。可以通过对运动机构的锁止，来对显示屏进行锁止。具体地，如：可以采用具有锁止功能的电机，通过电机的自锁，将链传动机构限位固定，进而将扩展部分21固定，从而实现对显示屏的锁止；或者，可以利用链轮41、链条43传动时的摩擦力将链传动机构锁止，进而实现对显示屏的锁止。
可选地，固定壳体1上固定有限位结构，限位结构将链传动机构的靠近固定部分20的一端限位固定。
可选地，在一示例中，限位结构可以为单向限位结构，该单向限位结构用于在扩展部分21向外运动时对链传动机构的靠近固定部分20的一端限位固定，而在扩展部分21向内运动时不对链传动机构的靠近固定部分20的一端限位固定。
具体地，在本实施例中，如图19和图20所示，限位结构设置为单向限位结构，单向限位结构包括设置在固定壳体1上的限位凸起11，限制链传动机构的最上侧靠近边缘的一根销轴432的运动，使其在柔性屏2的扩展部分21进行扩展运动的过程中保持不动。具体而言，电机驱动链轮41顺时针方向转动，链轮41带动链条43顺时针方向传动，最上侧靠近边缘的销轴432受到固定壳体1上的限位凸起11的限制，不能朝右运动，因此整个链条43会在 该限位凸起11的推力作用下向左展开。链条43向右展开会同步带动支撑机构、柔性屏2的扩展部分21以及滑动支撑板31向左展开。以上过程为柔性屏2的扩展部分21的扩展运动过程。
柔性屏2的扩展部分21的收纳运动过程刚好和柔性屏2的扩展部分21的展开过程相反。首先电机逆时针方向旋转，驱动链轮41逆时针方向旋转，进而带动链条43支撑机构、柔性屏2的扩展部分21、滑动支撑板31逆时针方向运动，由于柔性屏2的扩展部分21与固定部分20固定连接，连接力会限制扩展部分21向左运动，因此，链条43、支撑机构、下方的扩展部分21、滑动支撑板31会收纳于固定壳体1中。以上过程为柔性屏2的扩展部分21的收纳运动过程。
柔性屏2的扩展部分21的收纳运动过程与柔性屏2的扩展部分21的扩展运动过程的不同点在于，在收纳过程中，固定壳体1上的限位凸起11没有起到限位固定的作用，而是依靠扩展部分21与固定部分20的连接来实现该收纳运动过程。
可选地，在另一示例中，该限位结构可以为双向限位结构，双向限位结构用于在扩展部分21向外以及向内运动时对链传动机构的靠近固定部分20的一端限位固定。
具体地，如：双向限位结构可以包括固定件，该固定件将链传动机构的最上侧靠近边缘的一根销轴432与固定壳体1固定连接。
作为替代方案，当传动机构采用皮带传动机构时，只需用带轮替代链轮，用皮带替代链条即可；或者，当传动机构采用齿轮齿带传动机构时，只需用齿轮替代链轮，用齿带替代链条即可。
进一步，若皮带或齿带在拉紧到一定程度时，可以达到支撑柔性屏要求，可以用该皮带或齿带作为支撑机构，同时用作传动机构，进一步简化移动终端的结构。
可选地，在本实施例中，移动终端的显示屏为平面显示屏。
为了确保移动终端的显示屏为平面显示屏，将固定板10上的滑轨100与滑动支撑板31上的导轨312的导向段3120均设置成直线状。如图12所示，固定板10上的滑轨100为水平直线状，使滑动支撑板31相对于固定壳体1水平直线滑动；如图13所示，滑动支撑板31上的导轨312的导向段3120为水平直线状，使运动至壳体外的支撑机构也呈水平状，进而保证支撑在支撑机构上的扩展部分21呈水平状，这样在宽屏模式下壳体外的扩展部分21与固定部分20相水平，使固定部分20和至少部分扩展部分21构成的显示屏为平面显示屏。
可选地，移动终端还包括检测装置，检测装置用于检测柔性屏2的扩展程度。
具体地，检测装置可包括距离传感器和辅助检测装置，其中，距离传感器可发射检测脉冲，辅助检测装置可接收该检测脉冲，并通过测量检测脉冲的发射与接收之间的时间间隔来计算距离。该距离传感器可安装在滑动支撑板31上，辅助检测装置设置在移动终端的主板上。通过检测距离传感器和辅助检测装置之间的距离，可以得出滑动支撑板31的滑动伸出固定壳体1的距离，进而获得柔性屏2的扩展部分21的扩展程度，即柔性屏2的扩展程度，得出显示屏的大小。
可选地，移动终端还包括显示模块，用于显示柔性屏2的扩展程度。
可选地，柔性屏2的扩展部分21的扩展和收纳动作可自动控制实现。具体地，移动终端还包括自动控制模块，自动控制模块包括指令输入单元和控制单元。其中，指令输入单元用于接收扩展柔性屏2或收纳柔性屏2的指令；控制单元用于根据指令控制运动机构的电机动作，使柔性屏2的扩展部分21进行相应的扩展或收纳动作。
可选地，指令输入单元包括分别用于控制扩展柔性屏2和收纳柔性屏2的两个按键。具体地，该两个按键可以为实体按键，如可设置在固定壳体1上；或者可以为该自动控制模块对应的软件上的两个虚拟按键，实现柔性屏展开与收纳的一键操作控制。
可选地，当检测装置检测到柔性屏2的实际扩展程度与用户输入的指令不一致，控制单元可控制运动机构的电机进行动作，以调整柔性屏2的实际扩展程度，使其与用户输入的指令相一致。
可选地，当检测装置检测到柔性屏2的实际扩展程度达到最大，且此时输入的指令仍为对柔性屏2进行扩展的指令，则电机不动作；或者当检测装置检测到扩展部分21的扩展程度达到最小，且此时输入的指令仍为对柔性屏2进行收纳的指令，则电机不动作。
本实施例，通过设置支撑结构和运动机构两个核心结构，并充分利用柔性屏的优势，实现了柔性屏连续地展开与收纳，使显示屏可以在大屏和小屏之间自由变换，使用户在不同的使用需求下，在一定的范围内可以自由地设置显示屏的大小，从而可以满足人们日益丰富的需求。
本实施例还设置了检测装置，用以判断柔性屏的扩展百分比，即判断显示屏的大小，该检测装置可以采用距离传感器与相应的辅助检测装置实现。
本申请的实施例还设置了自动控制模块并通过软件控制实现，只需要在软件界面上设置两个按键(扩展柔性屏和收纳柔性屏)，外加一个显示模块供用户明确柔性屏的扩展程度即可，控制操作简单。
应当理解，支撑结构除了可以为本实施例所述的支撑机构加滑动支撑板的形式，还可以为其他形式，如可以为刚性支撑板加滑动支撑板的形式，其中在宽屏模式下，刚性支撑板可以随滑动支撑板的滑动移动至壳体外，并对运动至壳体外的扩展部分进行支撑，在窄屏模式下，刚性支撑板可以随滑动支撑板的滑动移动至壳体内。
实施例二：
本实施例提供了一种移动终端，其与实施例一所述的移动终端的不同之处主要在于，本实施例中，运动控制机构的动力源为手动驱动的动力源。
具体地，在本实施例中，如图21和图22所示，运动机构的动力源包括手动的驱动部40，该手动驱动部40可运动地安装在滑动支撑板31上，这样驱动部分40运动后可带动传动机构运动，传动机构带动支撑机构和扩展部分21进行扩展和收纳动作，同时带动滑动支撑板31滑动。
其中，该驱动部40可以相对于滑动支撑板31转动，转动的驱动部40带动传动机构运动，此时驱动部40的工作原理类似于电机；该驱动部40也可以相对于滑动支撑板31平移， 平移的驱动部40带动传动机构运动，传动机构一方面带动支撑机构和扩展部分21进行扩展和收纳动作，另一方面带动滑动支撑板31滑动，但是滑动支撑板31的滑动距离与驱动部40的平移距离不相等，故驱动部40会相对于滑动支撑板31发生平移。
应理解，该驱动部40也可以相对于滑动支撑板31固定安装，此时，可通过驱动部40带动滑动支撑板31移动，然后通过滑动支撑板31带动运动机构运动。
可选地，为了便于驱动该驱动部40进行运动，使该驱动部40的至少一部分凸出于滑动支撑板31的外侧，以便手动驱动该驱动部40。
可选地，驱动部40上设有防滑结构。如在本实施例中，驱动部40的外形为规则的凹凸形状，以避免转动驱动部40时打滑。
具体地，在本实施例中，如图21和图22所示，滑动支撑板31上设有安装孔313，以便传动轴42通过安装孔313后与驱动部40连接；传动轴42和驱动部40上设有相配合的旋转限位结构420和400，使传动轴42和驱动部40的周向固定，以便手动转动驱动部40后可带动传动轴42转动；传动轴42和链轮41上设有相配合的旋转限位结构421和410，以便实现传动轴42和链轮41的周向固定，以便传动轴42带动链轮41转动；驱动部40和滑动支撑板31上分别设有锁止凸起401和锁止凹槽314，以便在完成柔性屏2的扩展或者收纳后，使锁止凸起401和锁止凹槽314配合，从而可以阻止驱动部40旋转，进而达到锁定显示屏大小的目的。
可选地，驱动部40可伸缩地安装在滑动支撑板31上。即驱动部40能够向外伸出使驱动部40的至少一部分凸出于滑动支撑板31的外侧，并且驱动部40能够向内缩回使驱动部40的至少一部分位于滑动支撑板31内。
为了确保驱动部40拔出后不脱落，可以设置限位结构，如在滑动支撑板31上粘贴一个限位钢片或pc片等。
装配完成后，旋转限位结构420和400、旋转限位结构421和410始终处于相配合状态，使驱动部40、传动轴42和链轮41之间无法发生相对旋转。在需要对柔性屏2的扩展部分21进行扩展或者收纳的情况下，将驱动部40拔出，使锁止凸起401和锁止凹槽314脱离，用户可手动转动驱动部40，达到驱动链轮41的目的。在完成柔性幕的扩展或者收纳以后，可将驱动部40压回，使锁止凸起401和锁止凹槽314配合，从而可以阻止驱动部40旋转，进而达到锁定屏幕大小的目的。
在上述的结构中，锁止凸起401和/或锁止凹槽314可以设置有多个，以达到接近于在任意位置可锁定显示屏，提升用户体验的效果。
应当理解，也可以在驱动部40设置锁止凹槽314，在滑动支撑板31上设置锁止凸起401；或者可以利用其它结构实现驱动部40的锁止，如驱动部40与安装孔过盈配合，利用驱动部40与安装孔313之间的摩擦力将驱动部40锁止。
本实施例中，运动机构采用手动驱动，控制方式简单，结构实现方式也相对电机驱动要简单，使得移动终端整体结构简单，成本低。
实施例三：
如图23-图25所示，本实施例提供了一种移动终端，其与实施例一或实施例二所述的移动终端的不同之处主要在于，本实施例中，柔性屏2可以向两侧扩展。
具体地，在本实施例中，柔性屏2包括两扩展部分21、21’，两扩展部分21、21’位于柔性屏2的左右两侧，固定部分20位于柔性屏2的中部。相应地，运动机构和支撑结构的设置数量均为两个，且两运动机构分别用于带动两扩展部分21、21’运动，两支撑结构分别用于支撑两扩展部分21、21’。
进一步，两支撑结构的两滑动支撑板31、31’均与固定板10的内板面滑动连接。
如图25所示，固定板10的内板面上设置有滑轨100，两个滑动支撑板31、31’均与滑轨100滑动配合；并且两滑动支撑板31、31’的宽度(沿左右方向)之和与固定板10的宽度(沿左右方向)大致相等，以便两滑动支撑板31、31’能够带动扩展部分21、21’收纳会固定壳体1内。优选地，每一滑动支撑板31、31’的宽度为固定板10的宽度的一半，使得扩展部分21、21’扩展至最大后，显示屏为原来的2倍。
应当理解，也可以在固定板10的内板面上设置有两个滑轨，两个滑动支撑板31、31’分别与一个滑轨滑动配合。
本实施例实现了单个滑轨、向两侧扩展的方案，相对于实施例一或实施例二的方案，多了一套支撑结构和运动机构，使得移动终端在结构上的复杂程度提高，但本实施例的柔性屏2在两侧均可展开，用户可自主选择柔性屏2在左侧展开还是在右侧展开，或者在两侧同时展开，柔性屏2的展开方式将更加自由，用户体验效果更好。
实施例四：
如图26-图28所示，本实施例提供了一种移动终端，其柔性屏2可以向两侧扩展，但与实施例三所述的移动终端的不同之处主要在于，本实施例中，两支撑结构的两滑动支撑板31、31’分别与固定板10的内板面和外板面滑动连接。
相比于实施例三的单个滑轨、向两侧扩展的方案，本实施例实现了双滑轨、向两侧扩展的方案。
具体地，在本实施例中，固定板10的内板面和外板面上均设有滑轨100、100’，其中，内板面上的滑轨100支持柔性屏2的扩展部分21向左(或向右)扩展，外板面上的滑轨100’支持柔性屏2的扩展部分21’向右(或向左)扩展。
与实施例三的技术方案不同的是，本实施例的方案中，每一滑轨100、100’的长度(沿左右方向)均能与固定板10的宽度相等，每一滑动支撑板31、31’的宽度(沿左右方向)均与固定板10的宽度(沿左右方向)相等，因此左侧或右侧的扩展部分21、21’扩展至最大后，均能达到原始显示屏(即固定部分20)的大小，使得左右两侧的扩展部分21、21’分别向左侧和右侧完全扩展以后，整机的显示屏大小可以达到原始显示屏大小的三倍。
本实施例由于设置了内外侧的两个滑轨100、100’，实现了显示屏更大程度地扩展，使得整机的宽度相比实施例三的方案会增大；另外由于要实现三屏(即左侧的扩展部分21、固 定部分20、右侧的扩展部分21’)，在整机厚度上需要更大空间来对扩大的屏幕进行容纳，因此厚度较实施例三的方案也增大。
需要说明的是，虽然在附图27中，左侧展开的扩展部分21和右侧展开的扩展部分21’的高度不一致，但是左侧展开的扩展部分21和右侧展开的扩展部分21’的高度可以做到一致，只要保证左侧的支撑机构与右侧的支撑机构的高度一致即可，这样可保证固定在左右两侧的支撑机构上的扩展部分21和21’的高度一致。
目前虽然存在有部分折叠形式的三屏手机，但很难实现三屏之间的无缝连接，导致显示屏的显示效果不佳，而本实施例和实施例三中，可以实现三屏之间的无缝连接，显示效果更佳，且控制方式简单，整体操作便捷，能更好地满足用户的需求。
实施例五：
本实施例也提供了一种移动终端，其具有非平面显示屏。
本实施例是在实施例一的基础上，提出了非平面显示屏。为实现非平面显示屏的扩展，本实施例提出了非平面扩展方式，通过改变滑动支撑板31上的导轨和/或固定板10上的滑轨100的形状，来改变显示屏的扩展效果。
在此扩展方式下，滑动支撑板31上的导轨的导向段3120以及固定板10上的滑轨100的外形不再是与整机相平行的直线形状，而是弯曲的顺滑曲线形状。
当移动终端的显示屏为曲面显示屏，固定板10上的滑轨100与滑动支撑板31上的导轨312的导向段3120二者中的至少一者呈弯曲的顺滑曲线状，使得滑动支撑板31相对于固定壳体1不能直线滑动，和/或支撑在支撑机构上的扩展部分21不呈水平状，导致在宽屏模式下，由固定部分20和至少部分扩展部分21构成的显示屏为曲面显示屏。
下面结合附图，具体说明本实施例。
在非平面扩展方式下，实现非平面扩展的各个主要部件的结构如图29和图30所示。固定板10可通过粘胶的方式固定于固定壳体1上，滑动支撑板31与固定板10滑动连接。其中，固定板10上的滑轨100与滑动支撑板31上的导向段3120均为顺滑的曲线形状。由于运动机构、支撑机构、壳体等部件的结构和实施例一基本一致，因此为简化表示，在图中并未画出。
如图29和图30所示，柔性屏的固定部分20在宽屏模式和窄屏模式下始终处于水平平铺状态，当然固定部分20的状态不限于水平平铺，如果设计造型需要，也可以做成弯曲状，这个需要通过改变整机的外形来实现。
柔性屏2的扩展部分21在宽屏模式下的状态如图30所示，由图中可知，由扩展部分21和固定部分20构成的显示屏为曲面屏。
为了保证宽屏模式下，柔性屏的扩展部分21和固定部分20之间保持顺滑连接，不产生台阶感，扩展部分21与固定部分20相连接的一端要保证和固定部分20相切。
由于在柔性屏2的扩展部分21逐步展开过程中，滑动支撑板31在固定板10上滑过的距离是变化的，支撑机构与滑动支撑板31也发生相对运动，为保证扩展部分21与固定部分 20相连接的一端总是和固定部分20相切，需要滑轨100与导向段3120相配合。在本实施例中，滑轨100与导向段3120为圆弧状，且圆弧所在的圆是同心圆，且滑轨100与导向段3120的弯曲方向一致，半径相同，因此扩展部分21与固定部分20连接的一端总是和固定部分20相切，使得显示屏在该连接部位处是平滑过渡的。
在非平面扩展的方式下，扩展后显示屏的弯曲程度由滑轨100与导向段3120的弯曲程度来决定，滑轨100与导向段3120的弯曲程度越小，则扩展后的显示屏的弯曲程度越小，所需要的容纳空间也越小，整机的厚度可以相对较小；相反，滑轨100与导向段3120的弯曲程度越大，则扩展后显示屏的弯曲程度就越大，所需要的容纳空间也越大，整机的厚度会相应变厚。
非平面扩展方式，是通过改变滑轨100与导向段3120的形状来实现了显示屏的曲面扩展，在不增加工艺以及装配复杂程度的情况下，实现了显示屏扩展效果的改变，使扩展效果多样化，丰富了移动终端的显示屏的样式。
实施例六：
本实施例提供了一种控制方法，用于控制移动终端的柔性屏的扩展和收纳。
如图31所示，该控制方法包括以下步骤：
步骤110，获取扩展柔性屏或收纳柔性屏的指令；
步骤120，根据所述指令，控制运动机构动作，使柔性屏的扩展部分进行扩展或收纳运动。
可选地，当移动终端还包括用于检测柔性屏的扩展程度的检测装置时，该控制方法还包括以下步骤：
若获取的指令为扩展柔性屏的指令，且检测装置检测到柔性屏的扩展百分比达到最大，则控制运动机构停止动作；
若获取的指令为收纳柔性屏的指令，且检测装置检测到柔性屏的扩展百分比达到最小，则控制运动机构停止动作。
具体地，当检测装置检测到扩展部分的扩展程度达到最大，即柔性屏的扩展百分比达到100％，扩展部分已完全扩展时，柔性屏无法继续扩展，因此，若此时仍获取对柔性屏进行扩展的指令，则运动机构不动作；当检测装置检测到扩展部分的扩展程度达到最小，即柔性屏的扩展百分比达到0％，扩展部分已完全收纳时，柔性屏无法继续收纳，因此，若此时仍获取对柔性屏进行收纳的指令，则运动机构不动作。
可选地，所述指令包括为柔性屏指定的扩展程度(如可用扩展百分比来表示)；所述控制方法还包括：
当所述检测装置检测到的所述柔性屏的扩展程度与所述指定的扩展程度不一致时，控制所述运动机构动作，将所述柔性屏的扩展程度调整到所述指定的扩展程度。
具体而言，当获取的指令为扩展柔性屏且将柔性屏扩展到如30％时，若检测装置检测到柔性屏的实际扩展百分比与指令显示的扩展百分比30％不一致时，则控制运动机构动作来调 整柔性屏的实际扩展百分比，使实际扩展百分比与指令显示的扩展百分比一致。
下面结合图31，具体说明本实施例的控制方法。
本申请实施例的柔性屏的展开与收纳在使用电机驱动的驱动方式时，可以通过软件来实现一键操作。
想要用软件实现柔性屏展开与收纳的一键操作，首先需要在柔性屏的滑动支撑板上安装一个距离传感器，并在主板上设置一个辅助检测装置，通过检测传感器和辅助检测装置之间的距离，进而得出滑动支撑板伸出固定壳体的长短，进而得出柔性屏的扩展部分扩展的大小。
软件界面上只需要设置两个按键：一个是扩展柔性屏的按键，一个是收纳柔性屏的按键，并设置一个柔性屏扩展百分比的显示窗口即可。要得出柔性屏扩展的百分比，需要明确两个值，一个是柔性屏扩展到最大程度的时候距离传感器与辅助检测装置之间的距离Lmax(此时柔性屏扩展100％)，另一个是柔性屏没有扩展的时候距离传感器与辅助检测装置之间的距离Lmin(此时柔性屏扩展0％)。在任意具体的位置时，柔性屏扩展的百分比可以通过该距离传感器与辅助检测装置之间的距离L与两者之间的最大距离Lmax和最小距离Lmin之间通过简单的插值运算即可得出。
如图32所示，本实施例一个示例性的控制柔性屏扩展或收纳方法的流程如下：
首先，检测用户的输入；
若用户输入扩展屏幕的指令，则先检测柔性屏是否扩展到最大，即柔性屏的扩展百分比是否小于100％，若扩展百分比小于100％，则驱动电机顺时针旋转进行柔性屏的扩展；若扩展百分比不小于100％，则电机断电，显示柔性屏扩展到100％，并提示柔性屏已扩展到最大；
若用户输入收纳屏幕的指令，则先检测柔性屏是否扩展到最小，即柔性屏的扩展百分比是否大于0％，若扩展百分比大于0％，则驱动电机逆时针旋转进行柔性屏的收纳；若扩展百分比不大于0％，则电机断电，显示柔性屏扩展到0％，并提示柔性屏已完全收纳；
若未检测到用户的输入，则显示柔性屏的扩展百分比。
对于实施例二所示的使用手动驱动方式来作为链轮的驱动动力时，同样需要用距离传感器和相应的辅助检测装置来辅助判断柔性屏扩展或者收纳的程度，但控制方法和软件流程相对要简单很多，而且软件界面只能负责提示用户柔性屏扩展的程度，功能较为单一，无法用软件来控制柔性屏扩展的动作。在用户达到了自己所需要的柔性屏的大小的时候，需要手动停止对柔性屏的扩展或者收纳动作，使柔性屏的大小锁定在需要的显示屏状态。
本实施例还提供了一种控制系统，可实现本实施例的对柔性屏的控制方法。
如图33所示，该控制系统包括：
指令输入单元1001，其用于接收扩展柔性屏或收纳柔性屏的指令；
控制单元1003，其用于根据所述指令控制运动机构的动作。
可选地，指令输入单元包括分别用于控制扩展柔性屏和收纳柔性屏的两个按键。
可选地，所述控制系统还包括显示处理单元，用于接收检测装置对所述柔性屏扩展程度的检测结果并通过所述移动终端的显示屏显示，所述检测装置设置在所述移动终端上，用于检测所述柔性屏的扩展程度。
可选地，所述控制单元根据所述指令控制所述运动机构的动作，包括：
若接收的指令为扩展柔性屏的指令，且检测装置的检测结果为柔性屏的扩展程度达到最大，则控制单元控制运动机构停止动作；
若指令为收纳柔性屏的指令，且检测装置的检测结果为柔性屏的扩展程度达到最小，则控制单元控制运动机构停止动作。
可选地，所述指令中包括为所述柔性屏指定的扩展程度；所述控制单元根据所述指令控制所述运动机构的动作，包括：当所述检测装置检测到的所述柔性屏的扩展程度与所述指定的扩展程度不一致时，控制所述运动机构动作，将所述柔性屏的扩展程度调整到所述指定的扩展程度。
