The invention discloses an automatic rebounding roller shutter mechanism. A rotatable winding drum is arranged outside a fixed and non-rotating central shaft in a sleeving manner through bearings at the two ends; a spring is arranged on the central shaft in a sleeving manner; one end of the spring and the end part of one side of the winding drum are fixed and can synchronously rotate; the other end of the spring is fixed on a guide sleeve which can axially slide along the central shaft but cannot rotate; and the free length of the spring is smaller than that of the central shaft. According to the invention, the fixed end of the spring is fixed to one end of the winding drum, the movable end of the spring is arranged on the guide sleeve capable of moving in the axial direction the, and the torsion of the winding drum is converted into the thrust moving in the axial direction, so that stretching and retracting of the spring and sliding of the guide sleeve are achieved; the guide sleeve at the movable end only passively bears the thrust, and the stress is relatively low and even, so that sliding is smooth, jamming or damage is not easy, the sliding end is prevented from being damaged due to overlarge stress, and a sliding section can be protected to have the relatively long service life; and meanwhile, radial deformation of the spring is relieved, so that the spring is protected.
本发明公开了一种自动回弹的卷帘机构，可旋转的卷筒通过两端轴承套设在固定不旋转的中心轴外部；弹簧套设在中心轴上，弹簧的一端与卷筒的一侧端部固定可同步旋转，另一端固定在可沿中心轴轴向滑动、但不可转动的导向套上，弹簧的自由长度短于中心轴。本发明通过将弹簧的固定端与卷筒一端固定，弹簧活动端设置在可沿轴向移动的导向套上，将卷筒扭力转化为沿轴向移动的推力，实现弹簧的伸缩与导向套的滑移，活动端的导向套仅被动承受推力，受力较为舒缓平均，因而滑移顺畅，不易卡死或者损坏，从而避免滑动端受力过大导致损坏，也可以保护滑移段具有较长的使用寿命；同时缓解弹簧的径向形变，保护弹簧。
