Technical Problem
电子设备在折叠状态和展开状态之间切换时，柔性显示屏的弯曲半径变化，导致柔性显示屏在折叠前后被拉扯或挤压，影响电子设备的使用寿命
Benefits of technology
[0011]在本申请提供的电子设备中，通过设置第一支撑体和第三支撑体转动连接，使得第三支撑体能够相对于第二支撑体的旋转，从而实现支撑结构随着柔性显示屏一并折叠或展开，通过设置第一牵引绳和第二牵引绳，使得随着第一支撑体和第三支撑体相对转动，第一牵引绳和第二牵引绳能够牵引第二支撑体相对于第一支撑体滑动，以支撑具有不同弯曲半径的柔性显示屏，折叠状态和展开状态下的柔性显示屏均能被支撑结构良好支撑，在一定程度上避免或减小柔性显示屏被拉扯或挤压。相较于相关技术中的铰链组件，本申请中的第一牵引绳和第二牵引绳零部件少、结构简单，能够减轻支撑结构的重量，从而有利于支撑结构的轻薄化发展。采用第一牵引绳和第二牵引绳牵引第一支撑体相对第二支撑体平移，避免了相关技术中铰链组件的链环装配间隙较小，导致铰链组件连接的转动结构转动不畅或卡死的现象，避免了链环装配间隙较大，导致的铰链组件和其连接的转动结构存在的错动、松垮的现象。

Abstract
The application discloses an electronic device, and relates to the technical field of communication. The electronic device comprises a supporting structure and a flexible display screen, the supporting structure supports the flexible display screen, the supporting structure comprises a first supporting body, a second supporting body, a third supporting body and a traction assembly, the second supporting body is in sliding connection with the first supporting body; the third supporting body is in rotary connection with the first supporting body through a rotating shaft; the traction assembly comprises a first traction rope and a second traction rope, one end of the first traction rope and one end of the second traction rope are connected with the second supporting body, and the other end of the first traction rope and the other end of the second traction rope can be wound on the circumferential side of the rotating shaft in opposite directions; when the first supporting body and the third supporting body relatively rotate, the electronic device is switched between an unfolded state and a folded state, and the traction assembly drives the second supporting body to slide relative to the first supporting body so as to support the flexible display screen.
