Abstract

This utility model provides an electric lifting window using a chain-type servo motor, including a window frame, a lifting window sash, a fixed window sash, a servo motor, and a chain-type drive mechanism. The window frame includes an upper frame, a lower frame, a horizontal stile, and vertical frames. The lifting window sash is positioned between the upper frame, the horizontal stile, and the two vertical frames. The fixed window sash is positioned between the horizontal stile, the lower frame, and the two vertical frames. The servo motor is fixed inside the upper frame, and its motor shaft is powered by a sprocket assembly. The chain-type drive mechanism includes a drive chain, a chain fixing block, and a counterweight. The drive chain meshes with the sprocket assembly. A chain fixing block is fixed to the side of the lifting window sash, and one end of the drive chain is fixedly connected to the chain fixing block. A guide wheel mechanism is fixedly connected to the side of the lifting window sash, and a guide groove mechanism is fixedly connected to the inner side of the vertical frames. By using a chain-type servo motor to drive the lifting window sash to rise and fall, combined with the guide groove mechanism, the lifting accuracy is high, the stability is good, and the window sash is wear-resistant, resulting in a longer maintenance cycle.
