具体实施方式
为使本发明的目的、技术方案及优点更加清楚、明确，以下同时参照图 1- 图 9 ，并举实施例对本发明进一步详细说明。 应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
柔性屏具有可弯曲、柔韧性佳的特性，也被称为 OLED 屏。本发明所述可曲直转换的柔性屏可以适用于手机、电视、平板电脑等终端设备，用作终端设备的显示屏幕。
如图 1 所示，图 1 为本发明所述可曲直转换的柔性屏的较佳实施例的结构示意图。本发明所述可曲直转换的柔性屏，包括：柔性屏 1 及设置于所述柔性屏 1 的一侧、用于使所述柔性屏 1 进行曲直转换的动力机构。
现实使用中，将柔性屏 1 供用户观看的一侧称为柔性屏 1 的正面，将柔性屏 1 的正侧所对立的一侧称为背面，则所述动力机构设置于柔性屏 1 的背面，且位于柔性屏 1 的中部，使得动力机构运作时，能够带动整个柔性屏 1 进行一致的曲直转换，而不致于产生由于动力机构未在柔性屏 1 中部所导致的柔性屏 1 曲直转换不一致，即柔性屏 1 只有一端曲直转换，而另一端变形微弱，使得用户无法正常观看的问题。
如图 2 所示，图 2 是本发明所述可曲直转换的柔性屏中所述动力机构的较佳实施例的结构示意图。所述动力机构包括：伸缩臂和伸缩动力单元，所述伸缩动力单元与所述伸缩臂连接，当所述伸缩动力单元运作时，可以带动与其连接的伸缩臂产生水平方向的延伸和收缩，从而使得柔性屏 1 随着伸缩臂的延伸而弯曲，随着伸缩臂的收缩而拉直。
进一步的，如图 3 所示，图 3 是本发明所述可曲直转换的柔性屏中所述伸缩臂的较佳实施例的结构示意图。所述伸缩臂包括结构相同的第一伸缩臂 211 和第二伸缩臂 212 ， 所述第一伸缩臂 211 和第二伸缩臂 212 呈相对平行设置，即 第一伸缩臂 211 与第二伸缩臂 212 呈水平排列在一条直线上，且第一伸缩臂 211 与第二伸缩臂 212 之间具有第一间隙 213 ，所述伸缩动力单元设置于所述第一伸缩臂 211 与所述第二伸缩臂 212 之间的第一间隙 213 内。较佳的，所述伸缩臂为钢片。
本发明中，所述伸缩臂的伸缩是由第一间隙 213 的长度的增加和减少来决定的，即若第一间隙 213 的长度增加，则自第一伸缩臂 211 的顶端 A 至第二伸缩臂 212 的顶端 B 的总长度发生延伸；若第一间隙 213 的长度减少，则自第一伸缩臂 211 的顶端 A 至第二伸缩臂 212 的顶端 B 的总长度产生收缩，因此第一伸缩臂 211 与第二伸缩臂 212 在所述伸缩动力单元的动力传导下产生的运动为反向运动。当第一间隙 213 的长度增加，即第一伸缩臂 211 与第二伸缩臂 212 在伸缩动力单元的动力传导下均向远离对方的一端移动时，所述伸缩臂均对柔性屏 1 施加外力，其中第一伸缩臂 211 对与其连接处的柔性屏 1 施加向第二伸缩臂 212 反方向的外力，第二伸缩臂 212 对与其连接处的柔性屏 1 施加向第一伸缩臂 211 反方向的外力，而由于柔性屏 1 的长度不改变，因此柔性屏 1 在伸缩臂延伸所产生的外力作用下曲率发生改变，即柔性屏 1 发生弯曲。此时，若第一间隙 213 的长度减少，即第一伸缩臂 211 与第二伸缩臂 212 在伸缩动力单元的动力传导下均向靠近对方的一端移动时，所述伸缩臂均对柔性屏 1 施加外力，其中第一伸缩臂 211 对与其连接处的柔性屏 1 施加朝向第二伸缩臂 212 的外力，第二伸缩臂 212 对与其连接处的柔性屏 1 施加朝向第一伸缩臂 211 的外力，柔性屏 1 在伸缩臂总长度缩短所产生的外力作用下曲率发生改变，即柔性屏 1 由弯曲状态变直。
进一步的，如图 4 所示，图 4 是本发明所述可曲直转换的柔性屏中所述伸缩动力单元的较佳实施例的结构示意图。所述伸缩动力单元包括 分别设置在所述第一伸缩臂和所述第二伸缩臂的相对面上、并且齿的位置相对的第一齿条 22 1 和第二齿条 222 ，其中，所述第一齿条 221 的一端通过螺钉固定连接于第一伸缩臂 211 上，且位于第一伸缩臂 211 上朝向柔性屏 1 的一侧，另一端位于所述第一间隙 213 内；所述第二齿条 222 的一端固定连接于第二伸缩臂 212 上，且位于第一伸缩臂 211 上朝向柔性屏 1 的一侧，另一端也位于所述第一间隙 213 内。较佳的，所述第一齿条 221 与所述第二齿条 222 上下平行设置，即所述第一齿条 221 位于所述第二齿条 222 的上方，且平行于所述第二齿条 222 ，所述第一齿条 221 位于第一间隙 213 内的一端与所述第二齿条 222 位于第一间隙 213 内的一端之间具有第二间隙。进一步的，所述第一齿条 221 的齿与所述第二齿条 222 的齿的位置相对，即所述第一齿条 221 的齿位于其下表面；所述第二齿条 222 的齿位于其上表面。
所述伸缩动力单元还包括用于带动所述第一齿条 221 与所述第二齿条 222 进行反向运动的蜗杆传动单元。由于所述第一齿条 221 与第一伸缩臂 211 通过螺钉固定连接，所述第二齿条 222 与第二伸缩臂 212 通过螺钉固定连接，因此所述第一齿条 221 与所述第二齿条 222 在所述蜗杆传动单元的带动下进行反向运动时，所述第一伸缩臂 211 与所述第二伸缩臂 212 在第一齿条 221 与第二齿条 222 的反向运动的带动下，产生同样的方向相向的运动，实现伸缩臂总长度的增加或减少，从而将柔性屏 1 顶弯或拉直。
其中，所述蜗杆传动单元包括：相互配合的蜗杆 224 和蜗轮 225 ；延伸设置于蜗轮 225 的中心处、用于与所述第一齿条 221 及所述第二齿条 222 啮合传动的齿轮 226 。所述蜗轮 225 和蜗杆 224 相互配合，且位于所述第一间隙 213 内，当蜗杆 224 发生旋转时，与其相配合的蜗轮 225 同时产生旋转运动。在所述蜗轮 225 的中心处延伸设置有齿轮 226 ，即所述齿轮 226 的外表面超出所述蜗轮 225 的外表面，较佳的，所述蜗轮 225 与所述齿轮 226 连为一体，且所述齿轮 226 超出所述蜗轮 225 外表面的部分位于所述第二间隙内，且齿轮 226 与位于第一齿条 221 的下表面的齿、位于第二齿条 222 的上表面的齿均相配合。
当蜗轮 225 在蜗杆 224 的旋转带动下产生转动时，与蜗轮 225 一体化连接的齿轮 226 产生与蜗轮 225 相同方向的转动。较佳的，所述蜗杆 224 为右旋蜗杆，即当所述蜗杆 224 顺时针旋转时，所述蜗轮 225 逆时针旋转，则所述齿轮 226 产生与所述蜗轮 225 同样的逆时针转动，当齿轮 226 产生逆时针方向转动时，所述第一齿条 221 和所述第二齿条 222 均产生远离对方方向的运动，此时所述伸缩臂的总长度增加，所述伸缩臂均对柔性屏 1 施加外力，其中第一伸缩臂 211 对与其连接处的柔性屏 1 施加向第二伸缩臂 212 反方向的外力，第二伸缩臂 212 对与其连接处的柔性屏 1 施加向第一伸缩臂 211 反方向的外力，而由于柔性屏 1 的长度不改变，因此柔性屏 1 在伸缩臂延伸所产生的外力作用下曲率发生改变，即柔性屏 1 发生弯曲。所述蜗杆 224 逆时针旋转时，所述蜗轮 225 顺时针旋转，则所述齿轮 226 产生与所述蜗轮 225 同样的顺时针转动，当齿轮 226 产生顺时针方向转动时，所述第一齿条 221 和所述第二齿条 222 均产生朝向对方方向的运动，此时所述伸缩臂的总长度减少，所述伸缩臂均对柔性屏 1 施加外力，其中第一伸缩臂 211 对与其连接处的柔性屏 1 施加朝向第二伸缩臂 212 方向的外力，第二伸缩臂 212 对与其连接处的柔性屏 1 施加朝向第一伸缩臂 211 方向的外力，从而将弯曲的柔性屏 1 拉直。
进一步的，所述蜗杆 224 的一端设置有用于带动其转动的电机 227 。较佳的，所述电机 227 设置于所述蜗杆 224 的底端。
若所述动力机构偏向于所述柔性屏 1 的一侧，例如偏向于柔性屏 1 的左侧，则伸缩臂带动柔性屏 1 弯曲时，柔性屏 1 会产生左侧弯曲程度强于右侧弯曲程度的现象，不适宜用户观看，因此，较佳的，所述动力机构通过螺钉居中连接于所述柔性屏 1 的一侧，使得柔性屏 1 在居中设置于其一侧的动力机构的带动下，产生左右相同的弯曲，给用户提供较佳的曲屏观看视野。
进一步的，为了保持所述柔性屏 1 弯曲时的曲率一致，本发明中，在所述柔性屏 1 上设置有若干个螺钉柱 3 。如图 8 所示，图 8 是本发明中所述可曲直转换的柔性屏 1 中所述柔性屏 1 的背部的结构示意图。由于所述动力机构是通过螺钉连接于所述柔性屏 1 的一侧，因此在所述柔性屏 1 上设置螺钉柱 3 ，将动力机构与柔性屏 1 隔离开，即动力机构与柔性屏 1 之间相隔有若干个螺钉柱 3 ，且螺钉柱 3 的高度均相等，从而当动力机构带动柔性屏 1 弯曲时，由于动力机构与柔性屏 1 之间高度相等的螺钉柱 3 的设置，得以保持整个柔性屏 1 的弯曲曲率一致，从而给用户以最佳视角。
所述伸缩臂上间隔设置有若干个用于穿设螺钉的第一通孔 214 和第二通孔 215 ；所述第一通孔 214 设置于所述伸缩臂上远离所述伸缩动力单元的一端，且所述第一通孔 214 的内表面与螺钉的外表面相贴合；所述伸缩臂靠近所述伸缩动力单元的一端与所述第一通孔 214 之间间隔设置有所述第二通孔 214 ，且所述第二通孔 214 大于螺钉的外径。
所述螺钉柱 3 上设置有用于拧螺钉的凹槽。为了使得柔性屏 1 能在伸缩臂的动力带动下进行曲直转换运动，需要将伸缩臂的两端与柔性屏 1 固定连接，而伸缩臂的两端之间与柔性屏 1 的连接不能锁死，需要预留伸缩臂能够进行延伸和收缩的移动空间，因此在所述伸缩臂上远离所述伸缩动力单元的一端设置第一通孔 214 ，所述第一通孔 214 的内表面与螺钉的外表面相贴合，即所述第一通孔 214 刚好紧紧包裹螺钉，将伸缩臂远离所述伸缩动力单元的一端紧紧固定在柔性屏 1 上；在所述伸缩臂上靠近所述伸缩动力单元的一端与所述第一通孔 214 之间间隔设置若干个第二通孔 214 ，第二通孔 214 大于螺钉的外径，较佳的，所述第二通孔 214 为能够防止伸缩臂锁死，保持伸缩臂能水平移动的腰型孔。
进一步的，所述柔性屏 1 上还设置有用于固定蜗杆 224 和蜗轮 225 的定位座 4 ，其中，用于固定所述蜗杆 224 的为两个第一定位座 41 ，用于固定蜗轮 225 的为第二定位座 42 。所述蜗杆 224 通过第一定位座 41 及与所述第一定位座 41 相配合的定位帽 43 固定于柔性屏 1 的一侧。两个所述第一定位座 41 一上一下设置在柔性屏 1 上，所述第一定位座 41 的中部设置有与蜗杆 224 相配合的第一凹槽 411 ，所述第一定位座 41 的两端均设置有用于固定螺钉的第二凹槽 412 ，如图 5 和图 6 所示，图 5 是本发明所述可曲直转换的柔性屏 1 中所述定位帽的较佳实施例的结构示意图，图 6 是本发明所述可曲直转换的柔性屏 1 中所述第一定位座的较佳实施例的结构示意图。所述定位帽的两端设置有用于穿设螺钉的第三通孔 431 ，所述第三通孔与所述第二凹槽 412 的位置相配合。将蜗杆 224 置于第一凹槽 411 内，然后把定位帽与所述第一定位座 41 配合放置后，通过螺钉穿过所述定位帽上的第三通孔与所述第一定位座 41 上的第二凹槽 412 配合拧紧，从而将蜗杆 224 牢牢的固定在柔性屏 1 的一侧。
如图 7 所示，图 7 是本发明所述可曲直转换的柔性屏 1 中所述第二定位座的较佳实施例的结构示意图。用于固定蜗轮 225 的第二定位座 42 包括 : 与所述柔性屏 1 固定连接的底板 421 ；设置于所述底板的上下两端、用于防止所述第一齿条 221 及所述第二齿条 222 发生偏移的定位筋 422 ；设置于所述底板的中心、用于固定所述蜗轮 225 的旋转中心的定位柱 423 。
所述定位柱的中心处设置有用于固定螺钉的凹槽 424 ；由于所述蜗轮 225 的中部向外延伸设置有齿轮 226 ，因此，在蜗轮 225 的中部设置有通孔，所述通孔用于穿设螺钉，且贯穿蜗轮 225 的中心及所述齿轮 226 的中心。由于所述第一齿条 221 设置在所述齿轮 226 的上方，所述第二齿条 222 设置于所述齿轮 226 的下方，且所述第一齿条 221 及所述第二齿条 222 与所述齿轮 226 啮合传动，所述第一齿条 221 及所述第二齿条 222 均只有一段固定连接于伸缩臂上，因此所述第一齿条 221 及所述第二齿条 222 在与齿轮 226 的啮合传动过程中可能会发生外涨即产生向上或向下的偏移，本发明中，在用于固定蜗轮 225 的第二定位座 42 上设置定位筋，可以有效的防止所述第一齿条 221 及所述第二齿条 222 在与齿轮 226 的啮合传动过程中发生偏移，限制第一齿条 221 及第二齿条 222 在垂直方向的移动，保持第一齿条 221 及第二齿条 222 与齿轮 226 始终啮合，从而保持所述伸缩动力单元的正常运行。如图 9 和图 10 所示，图 9 是本发明中所述可曲直转换的柔性屏 1 曲屏状态时的俯视图，图 10 是本发明中所述可曲直转换的柔性屏 1 的爆炸示意图。
本发明还提供一种电视机，其包括所述的可曲直转换的柔性屏。较佳的，本发明还提供一用于与对所述电视机进行信号控制的遥控器；所述电视机还包括设置于所述电视机的内部，用于与所述遥控器及所述电机 227 进行信号传输的 MCU 控制芯片，所述 MCU 控制芯片与所述电机 227 电连接。
进一步的，所述遥控器上包括曲屏按键和直屏按键。当用户按下遥控器上的曲屏按键时，电视机内部的 MCU 控制芯片控制与蜗杆 224 相连的电机 227 进行顺时针旋转，从而带动蜗杆 224 产生顺时针的旋转运动，柔性屏 1 在伸缩臂延伸所述产生的外力作用下，发生弯曲，变为曲屏电视机；当用户按下遥控器上的直屏按键时，电视机内部的 MCU 控制芯片控制与蜗杆 224 相连的电机 227 进 行逆时针旋转，从而带动蜗杆 224 产生逆时针的旋转运动，柔性屏 1 在伸缩臂收缩所述产生的外力作用下被拉直，变为曲直屏电视机。用户可以根据实际需要，通过对遥控器上按键的简单操作，即可实现电视机曲屏和直屏的转换，方便快捷。
当电视机的当前状态为曲屏时，遥控器上的曲屏按键为不可用状态，遥控器上的直屏按键为可用状态，当用户使用曲屏按键时，遥控器可以对用户进行语音提醒，提示用户当前曲屏按键不可用；当电视机的当前状态为直屏时，遥控器上的曲屏按键为可用状态，遥控器上的直屏按键为不可用状态，当用户使用直屏按键时，遥控器可以对用户进行语音提醒，提示用户当前直屏按键不可用。
较佳的，所述电机 227 设置于所述蜗杆 224 的底端，所述蜗杆 224 的顶端还设置有圆环把手 228 ，所述圆环把手 228 伸出所述电视机的外表面，圆环把手 228 旋转时，蜗杆 224 产生与圆环把手 228 相同方向的旋转，即用户可以通过旋转圆环把手 228 ，自行调节柔性屏 1 的曲直转换。当柔性屏 1 在直屏状态时，若用户顺时针旋动所述圆环把手 228 ，柔性屏 1 由直屏转为曲屏；若用户逆时针旋动所述圆环把手 228 ，此时圆环把手 228 不会产生旋转运动，即用户不能旋动圆环把手 228 。当柔性屏 1 在曲屏状态时，用户逆时针旋动所述圆环把手 228 ，柔性屏 1 由曲屏转为直屏；若用户顺时针旋动所述圆环把手 228 ，此时圆环把手 228 不会产生旋转运动，即用户不能旋动圆环把手 228 。
综上所述，本发明提供 一种可曲直转换的柔性屏及电视机，其 包括：柔性屏及设置于所述柔性屏的一侧、用于使所述柔性屏进行曲直转换的动力机构；所述动力机构包括：伸缩臂及在所述伸缩臂上设置的用于使所述伸缩臂沿水平方向伸缩的伸缩动力单元。用户可以通过遥控器遥控或圆环把手自行手动调节柔性屏的曲直状态：在想要曲屏观看效果时，通过遥控器上的曲屏按键或者转动圆环把手，将柔性屏由直变曲，以达到良好的视觉效果；也可通过遥控器上的曲屏按键或者转动圆环把手，将柔性屏由曲变直，以供多人观看。
应当理解的是，本发明的应用不限于上述的举例，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，所有这些改进和变换都应属于本发明所附权利要求的保护范围。
技术领域
本发明涉及电视机技术领域，尤其涉及一种 可曲直转换的柔性屏及电视机 。
背景技术
目前，家庭中观看使用的电视机是普通直面电视机，适合多人观看，但是不能给用户提供最佳的视角，因此当用户想要提升视觉体验感时就要重新安置一台拥有一定曲面形态的曲面电视机（例如 OLED 电视机），以提供给用户良好的视觉效果，但是，曲面电视机不适合多人观看。普通直面电视机与曲面电视机均无法兼顾多人观看及良好的视觉效果，普通曲面电视机虽然采用的是可弯曲的柔性屏，但是其不可在曲面和直面之间相互转换，以满足用户在不同时刻的不同需求。
因此，现有技术还有待于改进和发展。

具体实施方式
为使本发明的目的、技术方案及优点更加清楚、明确，以下同时参照图 1- 图 9 ，并举实施例对本发明进一步详细说明。 应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
柔性屏具有可弯曲、柔韧性佳的特性，也被称为 OLED 屏。本发明所述可曲直转换的柔性屏可以适用于手机、电视、平板电脑等终端设备，用作终端设备的显示屏幕。
如图 1 所示，图 1 为本发明所述可曲直转换的柔性屏的较佳实施例的结构示意图。本发明所述可曲直转换的柔性屏，包括：柔性屏 1 及设置于所述柔性屏 1 的一侧、用于使所述柔性屏 1 进行曲直转换的动力机构。
现实使用中，将柔性屏 1 供用户观看的一侧称为柔性屏 1 的正面，将柔性屏 1 的正侧所对立的一侧称为背面，则所述动力机构设置于柔性屏 1 的背面，且位于柔性屏 1 的中部，使得动力机构运作时，能够带动整个柔性屏 1 进行一致的曲直转换，而不致于产生由于动力机构未在柔性屏 1 中部所导致的柔性屏 1 曲直转换不一致，即柔性屏 1 只有一端曲直转换，而另一端变形微弱，使得用户无法正常观看的问题。
如图 2 所示，图 2 是本发明所述可曲直转换的柔性屏中所述动力机构的较佳实施例的结构示意图。所述动力机构包括：伸缩臂和伸缩动力单元，所述伸缩动力单元与所述伸缩臂连接，当所述伸缩动力单元运作时，可以带动与其连接的伸缩臂产生水平方向的延伸和收缩，从而使得柔性屏 1 随着伸缩臂的延伸而弯曲，随着伸缩臂的收缩而拉直。
进一步的，如图 3 所示，图 3 是本发明所述可曲直转换的柔性屏中所述伸缩臂的较佳实施例的结构示意图。所述伸缩臂包括结构相同的第一伸缩臂 211 和第二伸缩臂 212 ， 所述第一伸缩臂 211 和第二伸缩臂 212 呈相对平行设置，即 第一伸缩臂 211 与第二伸缩臂 212 呈水平排列在一条直线上，且第一伸缩臂 211 与第二伸缩臂 212 之间具有第一间隙 213 ，所述伸缩动力单元设置于所述第一伸缩臂 211 与所述第二伸缩臂 212 之间的第一间隙 213 内。较佳的，所述伸缩臂为钢片。
本发明中，所述伸缩臂的伸缩是由第一间隙 213 的长度的增加和减少来决定的，即若第一间隙 213 的长度增加，则自第一伸缩臂 211 的顶端 A 至第二伸缩臂 212 的顶端 B 的总长度发生延伸；若第一间隙 213 的长度减少，则自第一伸缩臂 211 的顶端 A 至第二伸缩臂 212 的顶端 B 的总长度产生收缩，因此第一伸缩臂 211 与第二伸缩臂 212 在所述伸缩动力单元的动力传导下产生的运动为反向运动。当第一间隙 213 的长度增加，即第一伸缩臂 211 与第二伸缩臂 212 在伸缩动力单元的动力传导下均向远离对方的一端移动时，所述伸缩臂均对柔性屏 1 施加外力，其中第一伸缩臂 211 对与其连接处的柔性屏 1 施加向第二伸缩臂 212 反方向的外力，第二伸缩臂 212 对与其连接处的柔性屏 1 施加向第一伸缩臂 211 反方向的外力，而由于柔性屏 1 的长度不改变，因此柔性屏 1 在伸缩臂延伸所产生的外力作用下曲率发生改变，即柔性屏 1 发生弯曲。此时，若第一间隙 213 的长度减少，即第一伸缩臂 211 与第二伸缩臂 212 在伸缩动力单元的动力传导下均向靠近对方的一端移动时，所述伸缩臂均对柔性屏 1 施加外力，其中第一伸缩臂 211 对与其连接处的柔性屏 1 施加朝向第二伸缩臂 212 的外力，第二伸缩臂 212 对与其连接处的柔性屏 1 施加朝向第一伸缩臂 211 的外力，柔性屏 1 在伸缩臂总长度缩短所产生的外力作用下曲率发生改变，即柔性屏 1 由弯曲状态变直。
进一步的，如图 4 所示，图 4 是本发明所述可曲直转换的柔性屏中所述伸缩动力单元的较佳实施例的结构示意图。所述伸缩动力单元包括 分别设置在所述第一伸缩臂和所述第二伸缩臂的相对面上、并且齿的位置相对的第一齿条 22 1 和第二齿条 222 ，其中，所述第一齿条 221 的一端通过螺钉固定连接于第一伸缩臂 211 上，且位于第一伸缩臂 211 上朝向柔性屏 1 的一侧，另一端位于所述第一间隙 213 内；所述第二齿条 222 的一端固定连接于第二伸缩臂 212 上，且位于第一伸缩臂 211 上朝向柔性屏 1 的一侧，另一端也位于所述第一间隙 213 内。较佳的，所述第一齿条 221 与所述第二齿条 222 上下平行设置，即所述第一齿条 221 位于所述第二齿条 222 的上方，且平行于所述第二齿条 222 ，所述第一齿条 221 位于第一间隙 213 内的一端与所述第二齿条 222 位于第一间隙 213 内的一端之间具有第二间隙。进一步的，所述第一齿条 221 的齿与所述第二齿条 222 的齿的位置相对，即所述第一齿条 221 的齿位于其下表面；所述第二齿条 222 的齿位于其上表面。
所述伸缩动力单元还包括用于带动所述第一齿条 221 与所述第二齿条 222 进行反向运动的蜗杆传动单元。由于所述第一齿条 221 与第一伸缩臂 211 通过螺钉固定连接，所述第二齿条 222 与第二伸缩臂 212 通过螺钉固定连接，因此所述第一齿条 221 与所述第二齿条 222 在所述蜗杆传动单元的带动下进行反向运动时，所述第一伸缩臂 211 与所述第二伸缩臂 212 在第一齿条 221 与第二齿条 222 的反向运动的带动下，产生同样的方向相向的运动，实现伸缩臂总长度的增加或减少，从而将柔性屏 1 顶弯或拉直。
其中，所述蜗杆传动单元包括：相互配合的蜗杆 224 和蜗轮 225 ；延伸设置于蜗轮 225 的中心处、用于与所述第一齿条 221 及所述第二齿条 222 啮合传动的齿轮 226 。所述蜗轮 225 和蜗杆 224 相互配合，且位于所述第一间隙 213 内，当蜗杆 224 发生旋转时，与其相配合的蜗轮 225 同时产生旋转运动。在所述蜗轮 225 的中心处延伸设置有齿轮 226 ，即所述齿轮 226 的外表面超出所述蜗轮 225 的外表面，较佳的，所述蜗轮 225 与所述齿轮 226 连为一体，且所述齿轮 226 超出所述蜗轮 225 外表面的部分位于所述第二间隙内，且齿轮 226 与位于第一齿条 221 的下表面的齿、位于第二齿条 222 的上表面的齿均相配合。
当蜗轮 225 在蜗杆 224 的旋转带动下产生转动时，与蜗轮 225 一体化连接的齿轮 226 产生与蜗轮 225 相同方向的转动。较佳的，所述蜗杆 224 为右旋蜗杆，即当所述蜗杆 224 顺时针旋转时，所述蜗轮 225 逆时针旋转，则所述齿轮 226 产生与所述蜗轮 225 同样的逆时针转动，当齿轮 226 产生逆时针方向转动时，所述第一齿条 221 和所述第二齿条 222 均产生远离对方方向的运动，此时所述伸缩臂的总长度增加，所述伸缩臂均对柔性屏 1 施加外力，其中第一伸缩臂 211 对与其连接处的柔性屏 1 施加向第二伸缩臂 212 反方向的外力，第二伸缩臂 212 对与其连接处的柔性屏 1 施加向第一伸缩臂 211 反方向的外力，而由于柔性屏 1 的长度不改变，因此柔性屏 1 在伸缩臂延伸所产生的外力作用下曲率发生改变，即柔性屏 1 发生弯曲。所述蜗杆 224 逆时针旋转时，所述蜗轮 225 顺时针旋转，则所述齿轮 226 产生与所述蜗轮 225 同样的顺时针转动，当齿轮 226 产生顺时针方向转动时，所述第一齿条 221 和所述第二齿条 222 均产生朝向对方方向的运动，此时所述伸缩臂的总长度减少，所述伸缩臂均对柔性屏 1 施加外力，其中第一伸缩臂 211 对与其连接处的柔性屏 1 施加朝向第二伸缩臂 212 方向的外力，第二伸缩臂 212 对与其连接处的柔性屏 1 施加朝向第一伸缩臂 211 方向的外力，从而将弯曲的柔性屏 1 拉直。
进一步的，所述蜗杆 224 的一端设置有用于带动其转动的电机 227 。较佳的，所述电机 227 设置于所述蜗杆 224 的底端。
若所述动力机构偏向于所述柔性屏 1 的一侧，例如偏向于柔性屏 1 的左侧，则伸缩臂带动柔性屏 1 弯曲时，柔性屏 1 会产生左侧弯曲程度强于右侧弯曲程度的现象，不适宜用户观看，因此，较佳的，所述动力机构通过螺钉居中连接于所述柔性屏 1 的一侧，使得柔性屏 1 在居中设置于其一侧的动力机构的带动下，产生左右相同的弯曲，给用户提供较佳的曲屏观看视野。
进一步的，为了保持所述柔性屏 1 弯曲时的曲率一致，本发明中，在所述柔性屏 1 上设置有若干个螺钉柱 3 。如图 8 所示，图 8 是本发明中所述可曲直转换的柔性屏 1 中所述柔性屏 1 的背部的结构示意图。由于所述动力机构是通过螺钉连接于所述柔性屏 1 的一侧，因此在所述柔性屏 1 上设置螺钉柱 3 ，将动力机构与柔性屏 1 隔离开，即动力机构与柔性屏 1 之间相隔有若干个螺钉柱 3 ，且螺钉柱 3 的高度均相等，从而当动力机构带动柔性屏 1 弯曲时，由于动力机构与柔性屏 1 之间高度相等的螺钉柱 3 的设置，得以保持整个柔性屏 1 的弯曲曲率一致，从而给用户以最佳视角。
所述伸缩臂上间隔设置有若干个用于穿设螺钉的第一通孔 214 和第二通孔 215 ；所述第一通孔 214 设置于所述伸缩臂上远离所述伸缩动力单元的一端，且所述第一通孔 214 的内表面与螺钉的外表面相贴合；所述伸缩臂靠近所述伸缩动力单元的一端与所述第一通孔 214 之间间隔设置有所述第二通孔 214 ，且所述第二通孔 214 大于螺钉的外径。
所述螺钉柱 3 上设置有用于拧螺钉的凹槽。为了使得柔性屏 1 能在伸缩臂的动力带动下进行曲直转换运动，需要将伸缩臂的两端与柔性屏 1 固定连接，而伸缩臂的两端之间与柔性屏 1 的连接不能锁死，需要预留伸缩臂能够进行延伸和收缩的移动空间，因此在所述伸缩臂上远离所述伸缩动力单元的一端设置第一通孔 214 ，所述第一通孔 214 的内表面与螺钉的外表面相贴合，即所述第一通孔 214 刚好紧紧包裹螺钉，将伸缩臂远离所述伸缩动力单元的一端紧紧固定在柔性屏 1 上；在所述伸缩臂上靠近所述伸缩动力单元的一端与所述第一通孔 214 之间间隔设置若干个第二通孔 214 ，第二通孔 214 大于螺钉的外径，较佳的，所述第二通孔 214 为能够防止伸缩臂锁死，保持伸缩臂能水平移动的腰型孔。
进一步的，所述柔性屏 1 上还设置有用于固定蜗杆 224 和蜗轮 225 的定位座 4 ，其中，用于固定所述蜗杆 224 的为两个第一定位座 41 ，用于固定蜗轮 225 的为第二定位座 42 。所述蜗杆 224 通过第一定位座 41 及与所述第一定位座 41 相配合的定位帽 43 固定于柔性屏 1 的一侧。两个所述第一定位座 41 一上一下设置在柔性屏 1 上，所述第一定位座 41 的中部设置有与蜗杆 224 相配合的第一凹槽 411 ，所述第一定位座 41 的两端均设置有用于固定螺钉的第二凹槽 412 ，如图 5 和图 6 所示，图 5 是本发明所述可曲直转换的柔性屏 1 中所述定位帽的较佳实施例的结构示意图，图 6 是本发明所述可曲直转换的柔性屏 1 中所述第一定位座的较佳实施例的结构示意图。所述定位帽的两端设置有用于穿设螺钉的第三通孔 431 ，所述第三通孔与所述第二凹槽 412 的位置相配合。将蜗杆 224 置于第一凹槽 411 内，然后把定位帽与所述第一定位座 41 配合放置后，通过螺钉穿过所述定位帽上的第三通孔与所述第一定位座 41 上的第二凹槽 412 配合拧紧，从而将蜗杆 224 牢牢的固定在柔性屏 1 的一侧。
如图 7 所示，图 7 是本发明所述可曲直转换的柔性屏 1 中所述第二定位座的较佳实施例的结构示意图。用于固定蜗轮 225 的第二定位座 42 包括 : 与所述柔性屏 1 固定连接的底板 421 ；设置于所述底板的上下两端、用于防止所述第一齿条 221 及所述第二齿条 222 发生偏移的定位筋 422 ；设置于所述底板的中心、用于固定所述蜗轮 225 的旋转中心的定位柱 423 。
所述定位柱的中心处设置有用于固定螺钉的凹槽 424 ；由于所述蜗轮 225 的中部向外延伸设置有齿轮 226 ，因此，在蜗轮 225 的中部设置有通孔，所述通孔用于穿设螺钉，且贯穿蜗轮 225 的中心及所述齿轮 226 的中心。由于所述第一齿条 221 设置在所述齿轮 226 的上方，所述第二齿条 222 设置于所述齿轮 226 的下方，且所述第一齿条 221 及所述第二齿条 222 与所述齿轮 226 啮合传动，所述第一齿条 221 及所述第二齿条 222 均只有一段固定连接于伸缩臂上，因此所述第一齿条 221 及所述第二齿条 222 在与齿轮 226 的啮合传动过程中可能会发生外涨即产生向上或向下的偏移，本发明中，在用于固定蜗轮 225 的第二定位座 42 上设置定位筋，可以有效的防止所述第一齿条 221 及所述第二齿条 222 在与齿轮 226 的啮合传动过程中发生偏移，限制第一齿条 221 及第二齿条 222 在垂直方向的移动，保持第一齿条 221 及第二齿条 222 与齿轮 226 始终啮合，从而保持所述伸缩动力单元的正常运行。如图 9 和图 10 所示，图 9 是本发明中所述可曲直转换的柔性屏 1 曲屏状态时的俯视图，图 10 是本发明中所述可曲直转换的柔性屏 1 的爆炸示意图。
本发明还提供一种电视机，其包括所述的可曲直转换的柔性屏。较佳的，本发明还提供一用于与对所述电视机进行信号控制的遥控器；所述电视机还包括设置于所述电视机的内部，用于与所述遥控器及所述电机 227 进行信号传输的 MCU 控制芯片，所述 MCU 控制芯片与所述电机 227 电连接。
进一步的，所述遥控器上包括曲屏按键和直屏按键。当用户按下遥控器上的曲屏按键时，电视机内部的 MCU 控制芯片控制与蜗杆 224 相连的电机 227 进行顺时针旋转，从而带动蜗杆 224 产生顺时针的旋转运动，柔性屏 1 在伸缩臂延伸所述产生的外力作用下，发生弯曲，变为曲屏电视机；当用户按下遥控器上的直屏按键时，电视机内部的 MCU 控制芯片控制与蜗杆 224 相连的电机 227 进 行逆时针旋转，从而带动蜗杆 224 产生逆时针的旋转运动，柔性屏 1 在伸缩臂收缩所述产生的外力作用下被拉直，变为曲直屏电视机。用户可以根据实际需要，通过对遥控器上按键的简单操作，即可实现电视机曲屏和直屏的转换，方便快捷。
当电视机的当前状态为曲屏时，遥控器上的曲屏按键为不可用状态，遥控器上的直屏按键为可用状态，当用户使用曲屏按键时，遥控器可以对用户进行语音提醒，提示用户当前曲屏按键不可用；当电视机的当前状态为直屏时，遥控器上的曲屏按键为可用状态，遥控器上的直屏按键为不可用状态，当用户使用直屏按键时，遥控器可以对用户进行语音提醒，提示用户当前直屏按键不可用。
较佳的，所述电机 227 设置于所述蜗杆 224 的底端，所述蜗杆 224 的顶端还设置有圆环把手 228 ，所述圆环把手 228 伸出所述电视机的外表面，圆环把手 228 旋转时，蜗杆 224 产生与圆环把手 228 相同方向的旋转，即用户可以通过旋转圆环把手 228 ，自行调节柔性屏 1 的曲直转换。当柔性屏 1 在直屏状态时，若用户顺时针旋动所述圆环把手 228 ，柔性屏 1 由直屏转为曲屏；若用户逆时针旋动所述圆环把手 228 ，此时圆环把手 228 不会产生旋转运动，即用户不能旋动圆环把手 228 。当柔性屏 1 在曲屏状态时，用户逆时针旋动所述圆环把手 228 ，柔性屏 1 由曲屏转为直屏；若用户顺时针旋动所述圆环把手 228 ，此时圆环把手 228 不会产生旋转运动，即用户不能旋动圆环把手 228 。
综上所述，本发明提供 一种可曲直转换的柔性屏及电视机，其 包括：柔性屏及设置于所述柔性屏的一侧、用于使所述柔性屏进行曲直转换的动力机构；所述动力机构包括：伸缩臂及在所述伸缩臂上设置的用于使所述伸缩臂沿水平方向伸缩的伸缩动力单元。用户可以通过遥控器遥控或圆环把手自行手动调节柔性屏的曲直状态：在想要曲屏观看效果时，通过遥控器上的曲屏按键或者转动圆环把手，将柔性屏由直变曲，以达到良好的视觉效果；也可通过遥控器上的曲屏按键或者转动圆环把手，将柔性屏由曲变直，以供多人观看。
