这样设计的好处在于，支撑杆123可以避免可挠屏幕140在第二壳体120的所述收合过程中因行程差而产生挤压或皱折等不良状态，其中行程差是指在收合过程中，由于齿轮G1与齿条R1、R2的间隙，所以在微观上，可挠屏幕140的收合行程会落后第二壳体120的收合行程。一如前述，可挠屏幕140的可挠特性会因其不同状态而产生形状、尺寸的变化。为了让装置机构(例如第一壳体110与第二壳体120)的机构行程能与可挠屏幕140的变形量得以相符，本实施例通过提供可相对移动的第一壳体110与第二壳体120，且通过支撑杆123搭配轴承124、弹簧160用以支撑可挠屏幕140，以让可挠屏幕140因张力而被拉紧而达到所需。The advantage of this design is that the support rod 123 can avoid bad states such as squeezing or wrinkling of the flexible screen 140 due to stroke difference during the folding process of the second casing 120, wherein the stroke difference refers to During the process, due to the gap between the gear G1 and the racks R1 , R2 , the retraction stroke of the flexible screen 140 will lag behind the retraction stroke of the second housing 120 microscopically. As mentioned above, the flexible characteristics of the flexible screen 140 will produce changes in shape and size due to different states. In order to make the mechanism travel of the device mechanism (such as the first housing 110 and the second housing 120) consistent with the deformation of the flexible screen 140, this embodiment provides relatively movable first housing 110 and second housing 110. The housing 120 is used to support the flexible screen 140 through the supporting rod 123 with the bearing 124 and the spring 160, so that the flexible screen 140 can be tightened due to the tension to meet the requirement.

由于可挠屏幕能受到第二壳体的边框由上而下的压制及局限，所以在第二壳体的抽出过程中，可挠屏幕只需朝单方向展开。在其他实施例中，可挠式显示设备可朝左右方向拉开而得到更大的显示画面。一如前述，可挠屏幕的可挠特性会因其不同状态而产生形状、尺寸的变化。为了让装置机构(例如第一壳体与第二壳体)的机构行程能与可挠屏幕的变形量得以相符，本发明通过提供可相对移动的第一壳体与第二壳体并配合框架而达到所需。Since the flexible screen can be suppressed and limited by the frame of the second housing from top to bottom, the flexible screen only needs to unfold in one direction when the second housing is pulled out. In other embodiments, the flexible display device can be pulled apart in left and right directions to obtain a larger display screen. As mentioned above, the flexible characteristics of the flexible screen will produce changes in shape and size due to different states. In order to make the mechanism travel of the device mechanism (such as the first housing and the second housing) consistent with the deformation of the flexible screen, the present invention provides relatively movable first housing and second housing and cooperates with the frame And achieve the required.
