[0002] like Figure 1 and Figure 2 The figure shows the installation position diagram of the existing electric lifting window (lifting) power system. The power system is installed in the hollow crossbeam at the top of the electric lifting window. When installing, first install the sprocket box and connect the coupling to the main shaft of the sprocket box, then connect an L-shaped or T-shaped mounting bracket to the reduction motor (the drive shaft of the reduction motor penetrates the hole preset in the middle of the mounting bracket), move the reduction motor, make the drive shaft of the reduction motor dock with the coupling, and then fix the mounting bracket to the upper beam of the crossbeam from bottom to top with the fastening screws through the inspection hole preset in the bottom beam of the crossbeam; however, this installation method has the following disadvantages:

[0003] (1) The maintenance is difficult, time-consuming and laborious. Since the fastening screws are fastened from the bottom beam to the top beam, but there is an electric screen under the beam (blocking the inspection hole), the gap between the beam and the screen is limited (5mm). When the window reduction motor or sprocket box needs to be repaired or replaced, the electric screen must be removed before the reduction motor or sprocket box can be replaced. In addition, the maintenance difficulty is greatly increased (2-3 people are required to work together, and the replacement time is more than 4 hours);
