CROSS REFERENCE TO THE RELATED APPLICATIONS 
     This application is based upon and claims priority to Chinese Patent Application No. 202110112251.9, filed on Jan. 27, 2021, the entire contents of which are incorporated herein by reference. 
     TECHNICAL FIELD 
     The present invention relates to the technical field of louvres, particularly relates to an electric louvre, in particular to a rechargeable electric externally-hung venetian blind assembly. 
     BACKGROUND ART 
     Louvres are a style of windows, which originate from China. Mullion windows are applied to ancient Chinese buildings and are used in all dynasties from the Warring States Period to the Han Dynasty. The vertical bars are called mullion windows, and the horizontal bars are called horizontal lattice windows. The horizontal lattice window is an original style of the louvres, or, it can be called the original state of the louvres. 
     The modern louvres are invented by the Americans, named John Hampson, and a patent for the invention is granted on Aug. 21, 1841. The louvres are generally relatively wide, and are generally used for indoor and outdoor shading and ventilation. Louvre curtain walls that more and more people agree with also evolve from the louvres. The louvre curtain walls have many functional advantages and are very beautiful, and thus are generally used in high-rise buildings. Louvre is a window with louvres installed, which is different from a venetian blind. The venetian blind is similar to a curtain, which has smaller leaves, can be folded up and is common on our TVs or in daily lives. 
     However, in the process of implementing the technical solution in the prior art, the applicant finds the following technical problems in the technical solution in the prior art: 
     The main function of the electric louvres in the prior art is to electrically open and close up and down. Before the installation of the common electric louvres on the market at present, grooves need to be dug on walls to pre-bury wires, holes are drilled to reserve controller installation slots, then electric louvre controllers and electric louvres are installed, and the electric louvres are connected to the electric louvre controllers, thereafter the electric louvres can be controlled to ascend, descend and turn over, therefore the installation is very inconvenient, and sometimes the electric louvres cannot be controlled at all without electricity. 
     In addition, the common electric externally-hung curtains on the market at present are equipped with batteries in motors. It is inconvenient to connect charging wires when charging, and when the batteries are damaged, the batteries cannot be repaired or replaced. The venetian blinds are easily deformed and damaged during transportation.
