Abstract: A rechargeable electric externally-hung venetian blind assembly includes a venetian blind main body and a controller. The top of the venetian blind main body is provided with an upper cover, and the controller is detachably installed on the surface of the upper cover and controls the lifting and lowering of the venetian blind main body. Two ends of the upper cover are provided with a sealing cover, and the sealing cover and the upper cover enclose an accommodating space. When the venetian blind main body is in a tightened state, the venetian blind main body is accommodated in the accommodating space to avoid damage during transportation. The rechargeable electric externally-hung venetian blind assembly achieves the technical effects of convenient and safe transportation and easy installation, use and maintenance.
