Abstract: A smart sunshade curtain with a replaceable battery is provided which comprises a cross beam and mounting components covered on both ends of the cross beam; a power mechanism is disposed in the cross beam and has a drawer that may be pulled out of or pushed into one end of the cross beam, and battery assemblies are arranged in the drawer; a drive mechanism is disposed at the other end of the cross beam opposed to the power mechanism; the power mechanism transmits power to the drive mechanism to drive an output mechanism to move a curtain cloth. In the above structure, the batteries are arranged in sequence in the drawer mounted inside the cross beam, which facilitates spatial arrangement design of internal elements of the cross beam and prevents the batteries from being exposed to the outside, thereby improving aesthetics of the smart curtain.
