[0002] The balcony sliding window is opened by pulling up and down, which has the advantages of good ventilation effect, good air tightness, no space occupation, and easy cleaning. The balcony sliding window can be controlled by electric means to further improve the portability of the sliding window. However, the existing electric balcony sliding window usually installs the driving device on the movable window sash. When the movable window sash moves up and down, it will drive the power line, control line and other circuit structures of the driving device to move back and forth. It is necessary to set a wire winding or avoidance structure on the sliding window; or install the driving device above the window frame, and use a wire rope, chain or synchronous belt to drive the movable window sash to move. The overall structure of the electric balcony sliding window is relatively complicated and bloated, and it has high requirements for installation technicians and is difficult to install. There is no way to perform split assembly at the installation site. The entire electric balcony sliding window must be assembled and debugged in the factory, and then transported to the installation site for overall installation. This leads to the storage and transportation of the electric balcony sliding window. The transportation and installation costs are very high, especially for the electric balcony lifting windows as balcony windows of high-rise residential buildings. Due to the large size and complex structure of the lifting windows, the entire electric balcony lifting windows need to be hoisted to the installation site of the high-rise residential building, which greatly increases the installation cost and difficulty; moreover, due to the complex structure of the electric balcony lifting windows, the loading and unloading are difficult, the production cost and the subsequent maintenance cost are relatively high, and the subsequent maintenance is difficult to implement for high-rise balcony scenes; at the same time, when the movable window sash moves up and down, it will drive the power line, control line and other circuit structures of the driving device to move back and forth, which will cause the circuit structure to be repeatedly bent and easily cause fatigue damage, shorten the service life, and affect the safety and stability.
