The invention relates to a clutch transmission assembly of an electric sunshade curtain. The clutch transmission assembly is used in the electric sunshade curtain and connected between an electric motor of an electric driving mechanism and curtain cloth, the clutch transmission assembly comprises a transmission shaft pipe capable of unfolding and rolling the curtain cloth, and a ratchet wheel part and a transmission shaft sleeve which can be separated and combined relatively are arranged in the transmission shaft pipe. A space is reserved between the ratchet wheel part and the transmission shaft pipe, the transmission shaft sleeve can rotate along with the transmission shaft pipe and can axially and linearly move in the transmission shaft pipe, an elastic part is connected between the ratchet wheel part and the transmission shaft sleeve, so that the clutch transmission assembly is connected with the electric motor, and the transmission shaft pipe is connected with the curtain cloth. When a motor vehicle has an emergency shading requirement during running, a user can directly pull the curtain cloth by hand to be quickly unfolded, meanwhile, when the transmission shaft pipe is driven to rotate, the transmission shaft sleeve arranged in the transmission shaft pipe can be automatically separated from the ratchet wheel part, so that the pull-down force of the curtain cloth cannot be directly transmitted to the electric motor, and the electric motor is prevented from being damaged.
本发明涉及一种电动遮阳帘的离合传动组件,其用于电动遮阳帘中,且连接于电动驱动机构的电动马达与帘布之间,离合传动组件包括能展开与卷收帘布的传动轴管,于传动轴管内装设能相对离合的棘轮部件与传动轴套,棘轮部件与传动轴管之间具有间距,传动轴套则能与传动轴管一同旋转且能于传动轴管内部轴向直线移动,并以弹性部件连接棘轮部件与传动轴套之间,由此离合传动组件连接电动马达,传动轴管连接帘布,当机动车辆于行进间有紧急遮光需求时,使用者能够直接手拉帘布快速展开,同时,传动轴管被带动旋转时,设于传动轴管内部的传动轴套能自动与棘轮部件脱离,故能使帘布被下拉的力量不会直接传递至电动马达,确保电动马达不致损坏。
