所述滑动导向结构包括导向轴33和与导向轴33配合的导向套54，导向套设置在左侧连接板51和右侧连接板52的侧边。
所述运动机构还设置有转动打开和折拢柔性屏终端时增加阻力的结构，该机构可以用来提供随时停止转动随时定位功能的作用或仅起到提供操作手感的作用。如图8所示，该结构可以利用同步机构来设置，将齿轮连接架2的对应齿轮 21、24的齿轮轴的孔设置为簧管结构，用簧管结构夹紧齿轮21、24的齿轮轴，来提供阻力。
优选地，所述增加阻力的结构可以设置在滑动导向结构处，该结构包括簧管55，所述簧管55分别连接在左侧连接板51和右侧连接板52的侧边上，在簧管55的前后分别设置有所述导向套54，所述导向轴33分别连接在左侧支撑架和右侧支撑架上，所述簧管55夹紧导向轴33。这样，更有利于消除结构的间隙、提高品质，同时，阻力调节更加简单方便。
本发明应用于内折柔性屏终端时，柔性屏100处在移动终端的内侧，所述左侧机壳71和左侧连接板51通过螺丝连接，右侧机壳72和右侧连接板52连接，柔性屏分别与左侧机壳71和右侧机壳72固定连接，在柔性屏终端展平时，两侧由左侧机壳和右侧机壳中的支撑板对柔性屏支撑，中部有所述柔性屏支撑面10，在它们之间可由左侧活动支撑板61和右侧活动支撑板62支撑，在柔性屏终端从展平状态折拢时，柔性屏的两端能和左侧机壳71和右侧机壳72分别一起运动，而不是相对运动，无需再为遮蔽柔性屏的伸缩产生的间隙而增加机壳两端边框的宽度。
以上所述仅为本发明的具体实施例，但本发明的结构特征并不局限于此，可以预见本发明的运动机构可以应用于各种柔性屏移动终端中，任何本领域的技术人员在本发明的领域内，所作的变化或修饰皆涵盖在本发明的保护范围之中。
