The invention provides a novel power shaft assembly for a sunshade curtain and a sunshade curtain system. The power shaft assembly comprises an outer rotating shaft used for installing curtain cloth, a coil spring arranged in the outer rotating shaft, a first end block and a second end block, wherein the first end block and the second end block are arranged at the two ends of the outer rotating shaft respectively. At the first end block, one end of the outer rotating shaft and one end of the coil spring extend to the first end block, the coil spring is fixedly matched with the first end block in the rotating direction of the coil spring, and the outer rotating shaft is rotationally matched with the coil spring; at the second end block, the other end of the outer rotating shaft extends to the second end block and is rotatably installed on the second end block, and the other end of the coil spring does not extend to the second end block and is fixedly connected with the outer rotating shaft. The end, away from the first end block, of the coil spring does not extend to the end of the outer rotating shaft, that is, only the coil spring is arranged on the single side of the outer rotating shaft, so that the coil spring is short, the coil spring can evenly disperse pre-tightening torsion to all independent coils when releasing force, operation is more stable, and the coil spring has the long service life.

    本发明提供一种新型遮阳帘用的动力轴总成及遮阳帘系统,动力轴总成包括用于安装帘布的外转轴、设置在外转轴内的卷簧、以及分别设置在外转轴两端的第一端块和第二端块;在第一端块处:外转轴的一端和卷簧的一端都延伸至第一端块处,卷簧与第一端块在卷簧的转动方向上固定配合,外转轴与卷簧转动配合;在第二端块处:外转轴的另一端延伸至第二端块处、并可转动地安装于第二端块,卷簧的另一端未延伸至第二端块处、且与外转轴固定连接。卷簧远离第一端块的一端未延伸至外转轴的端部,即仅在外转轴的单侧设置了卷簧,使得卷簧长度较短,也就使得卷簧在释放力时能够均匀地将预紧扭力分散到各个单独线圈上,运行更加稳定,且卷簧具有较长的使用寿命。
